physicochemical properties and crystallization behavior. One to twenty mol% of YO3/2 were either added into the glass matrix or substituted for gallium oxide. The glass structure was studied by Raman spectroscopy, and the thermal, optical, thermo-mechanical and physical properties are examined. The introduction of yttrium ions in both glass series increases the glass transition temperature, crystallization temperature, softening temperature, coefficient of linear thermal expansion and density. Through differential scanning calorimetry and X-ray diffraction analyses, it was found that competition occurs between the gallo-germanate zeolite-type phase and the yttrium-containing phase. From 13 mol% of YO3/2, the yttrium introduction impedes the formation of surface crystallization in these glasses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photonic" title="photonic">photonic</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy-metal%20oxide" title=" heavy-metal oxide"> heavy-metal oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=glass" title=" glass"> glass</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a> </p> <a href="https://publications.waset.org/abstracts/167712/the-key-role-of-yttrium-oxide-on-devitrification-resilience-of-barium-gallo-germanate-glasses-physicochemical-properties-and-crystallization-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167712.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Gamma-Hydroxybutyrate (GHB): A Review for the Prehospital Clinician</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20Welch">Theo Welch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Gamma-hydroxybutyrate (GHB) is a depressant of the central nervous system with euphoric effects. It is being increasingly used recreationally in the United Kingdom (UK) despite associated morbidity and mortality. Due to the lack of evidence, healthcare professionals remain unsure as to the optimum management of GHB acute toxicity. Methods: A literature review was undertaken of its pharmacology and the emergency management of its acute toxicity.Findings: GHB is inexpensive and readily available over the Internet. Treatment of GHB acute toxicity is supportive. Clinicians should pay particular attention to the airway as emesis is common. Intubation is required in a minority of cases. Polydrug use is common and worsens prognosis. Conclusion: An inexpensive and readily available drug, GHB acute toxicity can be difficult to identify and treat. GHB acute toxicity is generally treated conservatively. Further research is needed to ascertain the indications, benefits, and risks of intubating patients with GHB acute toxicity. instructions give you guidelines for preparing papers for the conference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GHB" title="GHB">GHB</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma-hydroxybutyrate" title=" gamma-hydroxybutyrate"> gamma-hydroxybutyrate</a>, <a href="https://publications.waset.org/abstracts/search?q=prehospital" title=" prehospital"> prehospital</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency" title=" emergency"> emergency</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/141712/gamma-hydroxybutyrate-ghb-a-review-for-the-prehospital-clinician" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141712.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> The Capability of Organizational Leadership: Development of Conceptual Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kurmet%20Kivip%C3%B5ld">Kurmet Kivipõld</a>, <a href="https://publications.waset.org/abstracts/search?q=Maaja%20Vadi"> Maaja Vadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current paper develops the conceptual framework for organizational leadership capability. Organizational leadership here is understood as collective multi-level phenomenon which has been embedded into organizational processes as a capability at the level of the entire organization. The paper analyses and systematises the theo¬retical approaches to multi-level leadership in existing literature. This analysis marks the foundation of collective leadership at the organizational level, which forms the basis for the development of the conceptual framework of organi¬zational leadership capability. The developed conceptual framework of organiza¬tional leadership capability is formed from the synthesis of the three groups of base theories – traditional leadership theories, the resource-based view from strategic management and complexity theory from system theories. These conceptual sources present the main characteristics that determine the nature of organizational leadership capability and are the basis for its mea¬surement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leadership" title="leadership">leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20capability" title=" organizational capability"> organizational capability</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20leadership" title=" organizational leadership"> organizational leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=resource-based%20view" title=" resource-based view"> resource-based view</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20theory" title=" system theory"> system theory</a> </p> <a href="https://publications.waset.org/abstracts/77838/the-capability-of-organizational-leadership-development-of-conceptual-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> South Africa and U.S. AFRICOM: Reflections on a Lukewarm Relationship</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20Neethling">Theo Neethling</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The United States Africa Command (AFRICOM) was established in 2007 as a military and diplomatic entity and is intended to assist African states and military actors to address their security needs. At the same time, AFRICOM is clearly an extension of US strategic interests on the African continent. The challenge for the US Department of Defence is to project AFRICOM as a cooperative and willing partner. This implies a partner that offers needed services and resources, and supports African security and military priorities with no presumption of having a privileged role in defining the African future. However, one of AFRICOM’s main challenges relates to the point that it has not been able to secure a firm partnership with South Africa as a key player on the continent: South Africa has continuously taken a lukewarm, if not cold, approach towards AFRICOM since its formation. The main aim of this article is to examine and discuss South Africa’s political-military relations with AFRICOM and to assess the underlying reasons currently inhibiting AFRICOM from achieving a fully productive relationship with the South African government. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AFRICOM" title="AFRICOM">AFRICOM</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20African%20foreign%20policy" title=" South African foreign policy"> South African foreign policy</a>, <a href="https://publications.waset.org/abstracts/search?q=US%20interests" title=" US interests"> US interests</a>, <a href="https://publications.waset.org/abstracts/search?q=defence%20capabilities%20in%20Africa" title=" defence capabilities in Africa"> defence capabilities in Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=US-Africa%20relations" title=" US-Africa relations"> US-Africa relations</a> </p> <a href="https://publications.waset.org/abstracts/28650/south-africa-and-us-africom-reflections-on-a-lukewarm-relationship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Importance of Infrastucture Delivery and Management in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onyeka%20Nkwonta">Onyeka Nkwonta</a>, <a href="https://publications.waset.org/abstracts/search?q=Theo%20Haupt"> Theo Haupt</a>, <a href="https://publications.waset.org/abstracts/search?q=Karana%20Padayachee"> Karana Padayachee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims primarily to identify potential causes of the bottlenecks in the public sector that affect delivery and formulate evidence-based interventions to improve delivery and management of infrastructure projects. An initial literature review was carried out on infrastructural development and delivery in South Africa, with the aim to formulate evidence-based interventions to improve delivery within the sector. The infrastructure delivery management model was developed to map out best practice delivery processes. These will become the backbone on which improvement initiatives that will be developed within participating stakeholders. The model will, in turn, support a range of methodologies, including the risk system and a knowledge management framework. It will also look at key challenges facing departments with the ability to ensure knowledge and skills transfer at various sectors. The research is limited because the findings were based on existing literature. This study adopted an indirect approach for infrastructure management by focussing on the challenges faced and approaches adopted to overcome these challenges. This may narrow the consideration of some of the viewpoints, thereby limiting the richness of experience available to this research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title="infrastructure">infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges" title=" challenges"> challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/138074/importance-of-infrastucture-delivery-and-management-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138074.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Influence of the Coarse-Graining Method on a DEM-CFD Simulation of a Pilot-Scale Gas Fluidized Bed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20Ndereyimana">Theo Ndereyimana</a>, <a href="https://publications.waset.org/abstracts/search?q=Yann%20Dufresne"> Yann Dufresne</a>, <a href="https://publications.waset.org/abstracts/search?q=Micael%20Boulet"> Micael Boulet</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephane%20Moreau"> Stephane Moreau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The DEM (Discrete Element Method) is used a lot in the industry to simulate large-scale flows of particles; for instance, in a fluidized bed, it allows to predict of the trajectory of every particle. One of the main limits of the DEM is the computational time. The CGM (Coarse-Graining Method) has been developed to tackle this issue. The goal is to increase the size of the particle and, by this means, decrease the number of particles. The method leads to a reduction of the collision frequency due to the reduction of the number of particles. Multiple characteristics of the particle movement and the fluid flow - when there is a coupling between DEM and CFD (Computational Fluid Dynamics). The main characteristic that is impacted is the energy dissipation of the system, to regain the dissipation, an ADM (Additional Dissipative Mechanism) can be added to the model. The objective of this current work is to observe the influence of the choice of the ADM and the factor of coarse-graining on the numerical results. These results will be compared with experimental results of a fluidized bed and with a numerical model of the same fluidized bed without using the CGM. The numerical model is one of a 3D cylindrical fluidized bed with 9.6M Geldart B-type particles in a bubbling regime. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20dissipative%20mechanism" title="additive dissipative mechanism">additive dissipative mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=coarse-graining" title=" coarse-graining"> coarse-graining</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20element%20method" title=" discrete element method"> discrete element method</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed" title=" fluidized bed"> fluidized bed</a> </p> <a href="https://publications.waset.org/abstracts/176694/influence-of-the-coarse-graining-method-on-a-dem-cfd-simulation-of-a-pilot-scale-gas-fluidized-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176694.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Effectuating Theology of Culture: The Only Weapon to Confront 21st Century Global Godless Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hram%20Bik">Hram Bik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This is an analytical paper on how to apply theology to the global godless culture. The paper will analyze and materialize theology of culture and come up with theo-cultural principles which will enable Christians to properly engage with today godless culture. If theology and daily life are in any way split apart, Christians will lose the authenticity essential to their calling. Living out godliness in the ungodly culture requires materializing theology into daily life. To do that has become an unbeatable challenge for Christians in 21st century with the overtaking in of global godless culture enforced by Information Technology resulting in rapid and chaotic change of global lifestyles wherein Christianity stands in danger of being swallowed up. Staying away from the culture will rob Christianity of its mission to witness and staying with and like it will rob Christianity of its effectiveness. Thus the question is how should today Christians apply theology to the culture wherein what are said to be sins in the Bible no longer look like sins? Should we forge an all-out war against it or should distance ourselves away from it? The extreme response to it could fruit Christian Jihadism on the right and the apathetic response would let it booming with no one attempting to stop it on the left. This paper calls for global Christians to essentially make theology a part of their daily lives to form a united global force to influence the godless global culture by influencing our own family and community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christians" title="Christians">Christians</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20culture" title=" global culture"> global culture</a>, <a href="https://publications.waset.org/abstracts/search?q=godliness" title=" godliness"> godliness</a>, <a href="https://publications.waset.org/abstracts/search?q=theology" title=" theology"> theology</a> </p> <a href="https://publications.waset.org/abstracts/71780/effectuating-theology-of-culture-the-only-weapon-to-confront-21st-century-global-godless-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71780.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Graphene-Reinforced Silicon Oxycarbide Composite with Lamellar Structures Prepared by the Phase Transfer Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Yu">Min Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20T.%20Picot"> Olivier T.

With GO concentrations increasing up to 2 vol%, graphene-containing flakes self-assembled into a lamellar structure in the matrix leading to composite with the anisotropic property. Spark plasma sintering (SPS) was applied to densify the composites with four different GO concentrations (0, 0.5, 1 and 2 vol%) up to ~2.3 g/cm3. The fracture toughness of SiOC-2 vol% GO composites was significantly increased by ~91% (from 0.70 to 1.34 MPa·m¹/²), at the expense of a decrease in the flexural strength (from 85MPa to 55MPa), compared to SiOC-0 vol% GO composites. Moreover, the electrical conductivity in the perpendicular direction (σ┴=3×10⁻¹ S/cm) in SiOC-2 vol% GO composite was two orders of magnitude higher than the parallel direction (σ║=4.7×10⁻³ S/cm) owing to the self-assembled lamellar structure of graphene in the SiOC matrix. The composites exhibited increased electrical conductivity (σ┴) from 8.4×10⁻³ to 3×10⁻¹ S/cm, with the increasing GO content from 0.5 to 2 vol%. The SiOC-2 vol% GO composites further showed the better electrochemical performance of oxygen reduction reaction (ORR) than pure graphene, exhibiting a similar onset potential (~0.75V vs. RHE) and more positive half-wave potential (~0.6V vs. RHE). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20toughness" title=" fracture toughness"> fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20performance" title=" electrochemical performance"> electrochemical performance</a> </p> <a href="https://publications.waset.org/abstracts/87167/graphene-reinforced-silicon-oxycarbide-composite-with-lamellar-structures-prepared-by-the-phase-transfer-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87167.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Development of a Sensitive Electrochemical Sensor Based on Carbon Dots and Graphitic Carbon Nitride for the Detection of 2-Chlorophenol and Arsenic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20H.%20G.%20Moundzounga">Theo H.

An electrochemical sensor, based on graphitic carbon nitride (g-C₃N₄) and carbon dots (CDs), was fabricated and used for the determination of arsenic and 2-chlorophenol. The g-C₃N₄/CDs nanocomposite was prepared via microwave irradiation heating method and was dropped-dried on the surface of the glassy carbon electrode (GCE). Transmission electron microscopy (TEM), X-ray diffraction (XRD), photoluminescence (PL), Fourier transform infrared spectroscopy (FTIR), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS) were used for the characterization of structure and morphology of the nanocomposite. Electrochemical characterization was done by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The electrochemical behaviors of arsenic and 2-chlorophenol on different electrodes (GCE, CDs/GCE, and g-C₃N₄/CDs/GCE) was investigated by differential pulse voltammetry (DPV). The results demonstrated that the g-C₃N₄/CDs/GCE significantly enhanced the oxidation peak current of both analytes. The analytes detection sensitivity was greatly improved, suggesting that this new modified electrode has great potential in the determination of trace level of arsenic and 2-chlorophenol. Experimental conditions which affect the electrochemical response of arsenic and 2-chlorophenol were studied, the oxidation peak currents displayed a good linear relationship to concentration for 2-chlorophenol (R²=0.948, n=5) and arsenic (R²=0.9524, n=5), with a linear range from 0.5 to 2.5μM for 2-CP and arsenic and a detection limit of 2.15μM and 0.39μM respectively. The modified electrode was used to determine arsenic and 2-chlorophenol in spiked tap and effluent water samples by the standard addition method, and the results were satisfying. According to the measurement, the new modified electrode is a good alternative as chemical sensor for determination of other phenols. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title="electrochemistry">electrochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=limit%20of%20detection" title=" limit of detection"> limit of detection</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a> </p> <a href="https://publications.waset.org/abstracts/123651/development-of-a-sensitive-electrochemical-sensor-based-on-carbon-dots-and-graphitic-carbon-nitride-for-the-detection-of-2-chlorophenol-and-arsenic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123651.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Exploring the Relationship between Organisational Identity and Value Systems: Reflecting on the Values-Crafting Process in a Multi-National Organisation within the Entertainment Industry </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Veldsman">Dieter Veldsman</a>, <a href="https://publications.waset.org/abstracts/search?q=Theo%20Heyns%20Veldsman"> Theo Heyns Veldsman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The knowledge economy demands an organisation that is flexible, adaptable and able to navigate the ever-changing environment. This fast-paced environment has however resulted in an organizational landscape that battles to engage employees, retain top talent and create meaningful work for its members. In the knowledge economy, the concept of organizational identity has become an important consideration as organisations aim to create a compelling and inviting narrative for all stakeholders across the business value chain. Values are often seen as the behavioural framework that informs organisational culture, yet often values are perceived to be inauthentic and misaligned with the true character or identity of the organisation and how it is perceived by different role players. This paper focuses on exploring the relationship between organisational identity and value systems by focusing on a case study within a multi-national organisation within South Africa. The paper evaluates the implementation of mixed methods OD approach that gathered collaborative inputs of more than 4500 employees who participated in crafting the newly established values system post a retrenchment process. The paper will evaluate the relationship between the newly crafted value system and the identity of the organisation as described by various internal and external stakeholders in order to explore potential alignment, dissonance and key insights into understanding the relationship between organisational identity and values. The case study will be reported from the perspective of an OD consultant who supported the transformation process over a period of 8 months and aims to provide key insights into values and identity alignment within knowledge economy organisations. From a practical perspective, the paper provides insights into how values are created, perceived and lived within organisations and the impact on employee engagement and culture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=culture" title="culture">culture</a>, <a href="https://publications.waset.org/abstracts/search?q=organisational%20development" title=" organisational development"> organisational development</a>, <a href="https://publications.waset.org/abstracts/search?q=organisational%20identity" title=" organisational identity"> organisational identity</a>, <a href="https://publications.waset.org/abstracts/search?q=values" title=" values"> values</a> </p> <a href="https://publications.waset.org/abstracts/59224/exploring-the-relationship-between-organisational-identity-and-value-systems-reflecting-on-the-values-crafting-process-in-a-multi-national-organisation-within-the-entertainment-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59224.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> An Experimental Investigation of Chemical Enhanced Oil Recovery (Ceor) for Fractured Carbonate Reservoirs, Case Study: Kais Formation on Wakamuk Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jackson%20Andreas%20Theo%20Pola">Jackson Andreas Theo Pola</a>, <a href="https://publications.waset.org/abstracts/search?q=Leksono%20Mucharam"> Leksono Mucharam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hari%20Oetomo"> Hari Oetomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Budi%20Susanto"> Budi Susanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Wisnu%20Nugraha"> Wisnu Nugraha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> About half of the world oil reserves are located in carbonate reservoirs, where 65% of the total carbonate reservoirs are oil wet and 12% intermediate wet [1]. Oil recovery in oil wet or mixed wet carbonate reservoirs can be increased by dissolving surfactant to injected water to change the rock wettability from oil wet to more water wet. The Wakamuk Field operated by PetroChina International (Bermuda) Ltd. and PT. Pertamina EP in Papua, produces from main reservoir of Miocene Kais Limestone. First production commenced on August, 2004 and the peak field production of 1456 BOPD occurred in August, 2010. It was found that is a complex reservoir system and until 2014 cumulative oil production was 2.07 MMBO, less than 9% of OOIP. This performance is indicative of presence of secondary porosity, other than matrix porosity which is of low average porosity 13% and permeability less than 7 mD. Implementing chemical EOR in this case is the best way to increase oil production. However, the selected chemical must be able to lower the interfacial tension (IFT), reduce oil viscosity, and alter the wettability; thus a special chemical treatment named SeMAR has been proposed. Numerous laboratory tests such as phase behavior test, core compatibility test, mixture viscosity, contact angle measurement, IFT, imbibitions test and core flooding were conducted on Wakamuk field samples. Based on the spontaneous imbibitions results for Wakamuk field core, formulation of SeMAR with compositional S12A gave oil recovery 43.94% at 1wt% concentration and maximum percentage of oil recovery 87.3% at 3wt% concentration respectively. In addition, the results for first scenario of core flooding test gave oil recovery 60.32% at 1 wt% concentration S12A and the second scenario gave 96.78% of oil recovery at concentration 3 wt% respectively. The soaking time of chemicals has a significant effect on the recovery and higher chemical concentrations affect larger areas for wettability and therefore, higher oil recovery. The chemical that gives best overall results from laboratory tests study will also be a consideration for Huff and Puff injections trial (pilot project) for increasing oil recovery from Wakamuk Field <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wakamuk%20field" title="Wakamuk field">Wakamuk field</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20treatment" title=" chemical treatment"> chemical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20recovery" title=" oil recovery"> oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a> </p> <a href="https://publications.waset.org/abstracts/20988/an-experimental-investigation-of-chemical-enhanced-oil-recovery-ceor-for-fractured-carbonate-reservoirs-case-study-kais-formation-on-wakamuk-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20988.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">693</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Doing Durable Organisational Identity Work in the Transforming World of Work: Meeting the Challenge of Different Workplace Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20Heyns%20Veldsman">Theo Heyns Veldsman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Veldsman"> Dieter Veldsman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organisational Identity (OI) refers to who and what the organisation is, what it stands for and does, and what it aspires to become. OI explores the perspectives of how we see ourselves, are seen by others and aspire to be seen. It provides as rationale the ‘why’ for the organisation’s continued existence. The most widely accepted differentiating features of OI are encapsulated in the organisation’s core, distinctive, differentiating, and enduring attributes. OI finds its concrete expression in the organisation’s Purpose, Vision, Strategy, Core Ideology, and Legacy. In the emerging new order infused by hyper-turbulence and hyper-fluidity, the VICCAS world, OI provides a secure anchor and steady reference point for the organisation, particularly the growing widespread focus on Purpose, which is indicative of the organisation’s sense of social citizenship. However, the transforming world of work (TWOW) - particularly the potent mix of ongoing disruptive innovation, the 4th Industrial Revolution, and the gig economy with the totally unpredicted COVID19 pandemic - has resulted in the consequential adoption of different workplace strategies by organisations in terms of how, where, and when work takes place. Different employment relations (transient to permanent); work locations (on-site to remote); work time arrangements (full-time at work to flexible work schedules); and technology enablement (face-to-face to virtual) now form the basis of the employer/employee relationship. The different workplace strategies, fueled by the demands of TWOW, pose a substantive challenge to organisations of doing durable OI work, able to fulfill OI’s critical attributes of core, distinctive, differentiating, and enduring. OI work is contained in the ongoing, reciprocally interdependent stages of sense-breaking, sense-giving, internalisation, enactment, and affirmation. The objective of our paper is to explore how to do durable OI work relative to different workplace strategies in the TWOW. Using a conceptual-theoretical approach from a practice-based orientation, the paper addresses the following topics: distinguishes different workplace strategies based upon a time/place continuum; explicates stage-wise the differential organisational content and process consequences of these strategies for durable OI work; indicates the critical success factors of durable OI work under these differential conditions; recommends guidelines for OI work relative to TWOW; and points out ethical implications of all of the above. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organisational%20identity" title="organisational identity">organisational identity</a>, <a href="https://publications.waset.org/abstracts/search?q=workplace%20strategies" title=" workplace strategies"> workplace strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20world%20of%20work" title=" new world of work"> new world of work</a>, <a href="https://publications.waset.org/abstracts/search?q=durable%20organisational%20identity%20work" title=" durable organisational identity work"> durable organisational identity work</a> </p> <a href="https://publications.waset.org/abstracts/151531/doing-durable-organisational-identity-work-in-the-transforming-world-of-work-meeting-the-challenge-of-different-workplace-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151531.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Increases in Serum Erythropoietin Hormone in Recreational Breath-Hold Divers Following a Series of Repeated Apnoeas: Apnoea beyond Freediving</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonis%20Elia">Antonis Elia</a>, <a href="https://publications.waset.org/abstracts/search?q=Theo%20Loizou"> Theo Loizou</a>, <a href="https://publications.waset.org/abstracts/search?q=Gladys%20Onambele-Pearson"> Gladys Onambele-Pearson</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Barlow"> Matthew Barlow</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgina%20Stebbings"> Georgina Stebbings</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hypoxic conditions have been reported to enhance red blood cell production in both acclimatised low-landers and altitude adapted populations. This process is mediated by the erythropoietin hormone, which is released predominantly by the hypoxic kidney. A higher haemoglobin concentration was previously reported in elite breath-hold divers when compared to elite-skiers and untrained individuals. Therefore, the present study aimed to investigate whether apnoea induced hypoxia could induce a significant increase in serum erythropoietin concentration in recreational breath-hold divers which would provide an explanation to the higher haemoglobin levels observed in elite breath-hold divers. Identifying whether apnoea induced hypoxia induces a significant increase in serum erythropoietin might suggest that apnoea can be used as an alternative acclimatisation method to high altitude exposure. Seven healthy, recreational male breath-hold divers performed two sets of five 180 second breath-holds with a ten-minute supine rest between each set and a two-minute seated rest between each apnoea. During each breath-hold, participant’s heart rate and peripheral oxygen saturation levels were recorded every subsequent 10 seconds until the end of the 180 second breath-hold. After each 180 second breath-hold a capillary blood sample was collected from the finger to identify circulating haemoglobin levels. Following completion of the apnoeic protocol, three blood samples were collected at 30, 90 and 180 minutes to measure circulating erythropoietin levels. A significant interaction between erythropoietin and time was observed (F(3,18)= 4.72, p < 0.001), with significant increases in erythropoietin evident at 30 (t(6)= -5.035, p < 0.0590 (t(6)= -6.162, p < 0.05) and 180 (t(6)= - 7.232, p < 0.001) minutes post the last apnoea when compared to baseline. Corresponding average increases when compared to baseline were 16% at 30, 23% at 90 and 40% at 180 minutes post the last apnoea. A significant interaction between haemoglobin and time was observed (F(78,84)= 20.814, p < 0.001), with significant increases in haemoglobin evident at the fifth (t(29)= -1.124, p < 0.001), ninth (t(29)= -1.357, p < 0.001) and tenth (t(29)= -1.211, p < 0.05) apnoeas when compared to baseline. A significant interaction between peripheral oxygen saturation and time was observed (F(10,60)= 408.23, p < 0.001). The present study demonstrates that a series of ten 180 second breath-holds is sufficient to induce a significant increase in the circulating erythropoietin concentration of recreational breath hold divers. These observations may suggest that apnoea induced hypoxia may be used as an alternative acclimatisation method to high altitude exposure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apnoea" title="apnoea">apnoea</a>, <a href="https://publications.waset.org/abstracts/search?q=breath-holding" title=" breath-holding"> breath-holding</a>, <a href="https://publications.waset.org/abstracts/search?q=diving%20reflex" title=" diving reflex"> diving reflex</a>, <a href="https://publications.waset.org/abstracts/search?q=erythropoietin" title=" erythropoietin"> erythropoietin</a>, <a href="https://publications.waset.org/abstracts/search?q=haemoglobin" title=" haemoglobin"> haemoglobin</a> </p> <a href="https://publications.waset.org/abstracts/53069/increases-in-serum-erythropoietin-hormone-in-recreational-breath-hold-divers-following-a-series-of-repeated-apnoeas-apnoea-beyond-freediving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Navigating States of Emergency: A Preliminary Comparison of Online Public Reaction to COVID-19 and Monkeypox on Twitter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonia%20Egli">Antonia Egli</a>, <a href="https://publications.waset.org/abstracts/search?q=Theo%20Lynn"> Theo Lynn</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierangelo%20Rosati"> Pierangelo Rosati</a>, <a href="https://publications.waset.org/abstracts/search?q=Gary%20Sinclair"> Gary Sinclair</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The World Health Organization (WHO) defines vaccine hesitancy as the postponement or complete denial of vaccines and estimates a direct linkage to approximately 1.5 million avoidable deaths annually. This figure is not immune to public health developments, as has become evident since the global spread of COVID-19 from Wuhan, China in early 2020. Since then, the proliferation of influential, but oftentimes inaccurate, outdated, incomplete, or false vaccine-related information on social media has impacted hesitancy levels to a degree described by the WHO as an infodemic. The COVID-19 pandemic and related vaccine hesitancy levels have in 2022 resulted in the largest drop in childhood vaccinations of the 21st century, while the prevalence of online stigma towards vaccine hesitant consumers continues to grow. Simultaneously, a second disease has risen to global importance: Monkeypox is an infection originating from west and central Africa and, due to racially motivated online hate, was in August 2022 set to be renamed by the WHO. To better understand public reactions towards two viral infections that became global threats to public health no two years apart, this research examines user replies to threads published by the WHO on Twitter. Replies to two Tweets from the @WHO account declaring COVID-19 and Monkeypox as ‘public health emergencies of international concern’ on January 30, 2020, and July 23, 2022, are gathered using the Twitter application programming interface and user mention timeline endpoint. Research methodology is unique in its analysis of stigmatizing, racist, and hateful content shared on social media within the vaccine discourse over the course of two disease outbreaks. Three distinct analyses are conducted to provide insight into (i) the most prevalent topics and sub-topics among user reactions, (ii) changes in sentiment towards the spread of the two diseases, and (iii) the presence of stigma, racism, and online hate. Findings indicate an increase in hesitancy to accept further vaccines and social distancing measures, the presence of stigmatizing content aimed primarily at anti-vaccine cohorts and racially motivated abusive messages, and a prevalent fatigue towards disease-related news overall. This research provides value to non-profit organizations or government agencies associated with vaccines and vaccination programs in emphasizing the need for public health communication fitted to consumers' vaccine sentiments, levels of health information literacy, and degrees of trust towards public health institutions. Considering the importance of addressing fears among the vaccine hesitant, findings also illustrate the risk of alienation through stigmatization, lead future research in probing the relatively underexamined field of online, vaccine-related stigma, and discuss the potential effects of stigma towards vaccine hesitant Twitter users in their decisions to vaccinate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20marketing" title="social marketing">social marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health%20communication" title=" public health communication"> public health communication</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccines" title=" vaccines"> vaccines</a> </p> <a href="https://publications.waset.org/abstracts/155856/navigating-states-of-emergency-a-preliminary-comparison-of-online-public-reaction-to-covid-19-and-monkeypox-on-twitter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155856.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Hydroinformatics of Smart Cities: Real-Time Water Quality Prediction Model Using a Hybrid Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisa%20Coraggio">Elisa Coraggio</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawei%20Han"> Dawei Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiru%20Liu"> Weiru Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Theo%20Tryfonas"> Theo Tryfonas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water is one of the most important resources for human society. The world is currently undergoing a wave of urban growth, and pollution problems are of a great impact. Monitoring water quality is a key task for the future of the environment and human species.

Soft power refers to a country’s global reputation and their ability to leverage that reputation to achieve certain aims. South Korea has invested heavily in their soft power strategy for a multitude of predominantly historical and geopolitical reasons. On account of this investment and the global prominence of their strategy, South Korea was considered to be the optimal candidate for the aims of this investigation. Having isolated the entertainment industry as one of the most heavily funded segments of the South Korean soft power strategy, the analysis restricted itself to this sector. Within this industry, two entertainment products were selected as case studies. The case studies were chosen based on commercial success according to metrics such as streams, purchases, and subsequent revenue. This criterion was deemed to be the most objective and verifiable indicator of the products general appeal. The entertainment products which met the chosen criterion were Netflix’ “Squid Game” and BTS’ hit single “Butter”. The methodologies employed were chosen according to the medium of the entertainment products. For “Squid Game,” an aesthetic analysis was carried out to investigate how multi- layered meanings were mobilized in a show popularized by its visual grammar. To examine “Butter”, both music semiology and linguistic analysis were employed. The music section featured an analysis underpinned by denotative and connotative music semiotic theories borrowing from scholars Theo van Leeuwen and Martin Irvine. The linguistic analysis focused on stance and semantic fields according to scholarship by George Yule and John W. DuBois. The aesthetic analysis of the first case study revealed intertextual references to famous artworks, which served to augment the emotional provocation of the Squid Game narrative. For the second case study, the findings exposed a set of musical meaning units arranged in a patchwork of familiar and futuristic elements to achieve a song that existed on the boundary between old and new. The linguistic analysis of the song’s lyrics found a deceptively innocuous surface level meaning that bore implications for authority, intimacy, and commercial success. Whether through means of visual metaphor, embedded auditory associations, or linguistic subtext, the collective findings of the three analyses exhibited a desire to conjure a form of positive arousal in the spectator. In the synthesis section, this process is likened to that of branding. Through an exploration of branding, the entertainment products can be understood as cogs in a larger operation aiming to create positive associations to Korea as a country and a concept. Limitations in the form of a timeframe biased perspective are addressed, and directions for future research are suggested. This paper employs semiotic methodologies to examine two entertainment products as mechanisms of soft power. Through means of visual metaphor, embedded auditory associations, or linguistic subtext, the findings reveal a desire to conjure positive arousal in the spectator. The synthesis finds similarities to branding, thus positioning the entertainment products as cogs in a larger operation aiming to create positive associations to Korea as a country and a concept. <p
