Coaches constantly encounter ambiguity, as they are unable to have complete certainty regarding the perspectives and expectations of stakeholders. Moreover, the coaching environment is characterised by its dynamic nature and intricate micro-political dynamics which further add to the complexity that coaches must navigate. This research study offers a unique perspective on the practical manifestation of coaching effectiveness in the South African (SA) context, where the sport is in its early stages of development. With a predominant presence of male coaches training female players and players originating from diverse sporting backgrounds, including a majority of those who commence their rugby careers at the university level, this exploration, along with practical recommendations, becomes essential. It allows for a nuanced understanding of coaching practices within a rugby system that concurrently focuses on development and high performance. By integrating the views of both players and coaches, insights are gained that extend traditional assessments, enabling a comprehensive understanding of coaching effectiveness and its implications in this evolving Women’s Rugby landscape. Through semi-structured interviews, the research delves into their assessments of coaching strategies, methodologies, and outcomes, aiming to understand coaching efficacy and its impact on player development. The findings contribute to a nuanced understanding of coaching effectiveness, paving the way for evidence-based recommendations to enhance coaching development and positively impact the sport's growth and success in SA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=women%E2%80%99s%20rugby" title="women’s rugby">women’s rugby</a>, <a href="https://publications.waset.org/abstracts/search?q=coaching%20effectiveness" title=" coaching effectiveness"> coaching effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=coaching" title=" coaching"> coaching</a>, <a href="https://publications.waset.org/abstracts/search?q=rugby" title=" rugby"> rugby</a>, <a href="https://publications.waset.org/abstracts/search?q=coaching%20education" title=" coaching education"> coaching education</a> </p> <a href="https://publications.waset.org/abstracts/185219/enhancing-coaching-development-in-south-african-womens-rugby-insights-from-coaches-and-players-on-effectiveness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185219.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">53</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> A Simple Device for in-Situ Direct Shear and Sinkage Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Jerves">A.

It consists of a box nested within a larger box. Both have open bottoms, allowing them to be lowered into the material. Afterwards, two rotating plates on opposite sides of the outer box will rotate outwards in order to clear regolith on either side, providing room for the inner box to move relative to the plates and perform a shear test without the resistance of the surrounding soil. From this test, Coulomb parameters, including cohesion and internal friction angle, as well as, Bekker parameters can be inerred. This device has been designed for a laboratory setting, but with few modications, could be put on the underside of a rover for use in a remote location. The goal behind this work is to ultimately create a compact, but accurate measuring tool to put onto a rover or any kind of exploratory vehicle to test for regolith properties of celestial bodies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=simple%20shear" title="simple shear">simple shear</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20angle" title=" friction angle"> friction angle</a>, <a href="https://publications.waset.org/abstracts/search?q=Bekker%20parameters" title=" Bekker parameters"> Bekker parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=device" title=" device"> device</a>, <a href="https://publications.waset.org/abstracts/search?q=regolith" title=" regolith"> regolith</a> </p> <a href="https://publications.waset.org/abstracts/20915/a-simple-device-for-in-situ-direct-shear-and-sinkage-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20915.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">509</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> A Machine Learning Decision Support Framework for Industrial Engineering Purposes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anli%20Du%20Preez">Anli Du Preez</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Bekker"> James Bekker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data is currently one of the most critical and influential emerging technologies. However, the true potential of data is yet to be exploited since, currently, about 1% of generated data are ever actually analyzed for value creation. There is a data gap where data is not explored due to the lack of data analytics infrastructure and the required data analytics skills. This study developed a decision support framework for data analytics by following Jabareen’s framework development methodology. The study focused on machine learning algorithms, which is a subset of data analytics. The developed framework is designed to assist data analysts with little experience, in choosing the appropriate machine learning algorithm given the purpose of their application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Data%20analytics" title="Data analytics">Data analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=Industrial%20engineering" title=" Industrial engineering"> Industrial engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=Machine%20learning" title=" Machine learning"> Machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Value%20creation" title=" Value creation"> Value creation</a> </p> <a href="https://publications.waset.org/abstracts/116912/a-machine-learning-decision-support-framework-for-industrial-engineering-purposes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116912.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">168</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> Multivariate Simulations of the Process of Forming the Automotive Connector Forging from ZK60 Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Dziubinska">Anna Dziubinska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article presents the results of numerical simulations of the new forging process of the automotive connector forging from cast preform. The high-strength ZK60 alloy (belonging to the Mg-Zn-Zr group of Mg alloys) was selected for numerical tests. Currently, this part of the industry is produced by multi-stage forging consisting of operations: bending, preforming, and finishing. The use of the cast preform would enable forging this component in one operation. However, obtaining specific mechanical properties requires inducing a certain level of strain within the forged part. Therefore, the design of the preform, its shape, and volume are of paramount importance. In work presented in this article, preforms of different shapes were designed and assessed using Finite Element (FE) analysis.

The population of this research included all personnel of the National Iranian Gas Company's sports personnel (150 people). For collecting information, library resources and three questionnaires, organizational political behavior by Kaspar and Carlsen (1997), Lewall's moral values questionnaire (1986) and job enthusiasm questionnaire Schaufeli & Bekker (2003) have been used. Validity of the questionnaires was confirmed by university professors. Using Cronbach alpha correlation coefficient, the reliability of the organizational political behavior questionnaire was 0.92, the moral values questionnaire was 0.86 and the Schaufeli & Baker job enthusiasm questionnaire was 0.91-0.96. The results of this research show a significant, direct and positive relationship between the components of job aspiration with political behavior and ethical values. Therefore, managers of organizations should, as far as possible, remove political behaviors from the organization and be able to institutionalize ethical values in their organization so that they can increase employee eagerness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20behavior" title="political behavior">political behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=ethical%20values" title=" ethical values"> ethical values</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20enthusiasm" title=" job enthusiasm"> job enthusiasm</a>, <a href="https://publications.waset.org/abstracts/search?q=staff" title=" staff"> staff</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20Iranian%20gas%20company" title=" national Iranian gas company"> national Iranian gas company</a> </p> <a href="https://publications.waset.org/abstracts/122558/the-relationship-between-organizational-political-behavior-and-moral-values-with-work-engagement-in-sport-employees-of-national-iranian-gas-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122558.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">118</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> Mobile Application Interventions in Positive Psychology: Current Status and Recommendations for Effective App Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gus%20Salazar">Gus Salazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeremy%20Bekker"> Jeremy Bekker</a>, <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Linford"> Lauren Linford</a>, <a href="https://publications.waset.org/abstracts/search?q=Jared%20Warren"> Jared Warren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Positive psychology practices allow for its principles to be applied to all people, regardless of their current level of functioning. To increase the dissemination of these practices, interventions are being adapted for use with digital technology, such as mobile apps. However, the research regarding positive psychology mobile app interventions is still in its infancy. In an effort to facilitate progress in this important area, we 1) conducted a qualitative review to summarize the current state of the positive psychology mobile app literature and 2) developed research-supported recommendations for positive psychology app development to maximize behavior change. In our literature review, we found that while positive psychology apps varied widely in content and purpose, there was a near-complete lack of research supporting their effectiveness. Most apps provided no rationale for the behavioral change techniques (BCTs) they employed in their app, and most did not develop their app with specific theoretical frameworks or design models in mind. Given this problem, we recommended four steps for effective positive psychology app design. First, developers must establish their app in a research-supported theory of change. Second, researchers must select appropriate behavioral change techniques which are consistent with their app’s goals. Third, researchers must leverage effective design principles. These steps will help mobile applications use data-driven methods for encouraging behavior change in their users. Lastly, we discuss directions for future research. In particular, researchers must investigate the effectiveness of various BCTs in positive psychology interventions. Although there is some research on this point, we do not yet clearly understand the mechanisms within the apps that lead to behavior change. Additionally, app developers must also provide data on the effectiveness of their mobile apps. As developers follow these steps for effective app development and as researchers continue to investigate what makes these apps most effective, we will provide millions of people in need with access to research-based mental health resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavioral%20change%20techniques" title="behavioral change techniques">behavioral change techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20app" title=" mobile app"> mobile app</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20intervention" title=" mobile intervention"> mobile intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20psychology" title=" positive psychology"> positive psychology</a> </p> <a href="https://publications.waset.org/abstracts/139080/mobile-application-interventions-in-positive-psychology-current-status-and-recommendations-for-effective-app-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139080.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">224</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> Psychometric Properties of Several New Positive Psychology Measures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Benyo%20Linford">Lauren Benyo Linford</a>, <a href="https://publications.waset.org/abstracts/search?q=Jared%20Warren"> Jared Warren</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeremy%20Bekker"> Jeremy Bekker</a>, <a href="https://publications.waset.org/abstracts/search?q=Gus%20Salazar"> Gus Salazar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to accurately identify areas needing improvement and track growth, the availability of valid and reliable measures of different facets of well-being is vital. Because no specific measures currently exist for many facets of well-being, the purpose of this study was to construct and validate measures of the following constructs: Purpose, Values, Mindfulness, Savoring, Gratitude, Optimism, Supportive Relationships, Interconnectedness, Compassion, Community, Contribution, Engaged Living, Personal Growth, Flow Experiences, Self-Compassion, Exercise, Meditation, and an overall measure of subjective well-being—the Survey on Flourishing. In order to assess their psychometric properties, each measure was examined for internal consistency estimates, and items with poor item-test correlations were dropped. Additionally, the convergent validity of the Survey on Flourishing (SURF) was assessed. Total score correlations of SURF and other commonly used measures of well-being such as the Positive and Negative Affect Schedule (PANAS), The Satisfaction with Life Scale (SWLS), the PERMA Profiler (measure of Positive Emotion, Engagement, Relationships, Meaning, and Achievement) were examined to establish convergent validity. The Kessler Psychological distress scale (K6) was also included to determine the divergent validity of the SURF measure. Three week test-retest reliability was also assessed for the SURF measure. Additionally, normative data from general population samples was collected for both the Self-Compassion and Survey on Flourishing (SURF) measures. The purpose of this study is to introduce each of these measures, divulge the psychometric findings of this study, as well as explore additional psychometric properties of the SURF measure in particular. This study will highlight how these measures can be used in future research exploring these positive psychology constructs. Additionally, this study will discuss the utility of these measures to guide individuals in their use of the online self-directed, self-administered My Best Self 101 positive psychology resources developed by the researchers. The goal of My Best Self 101 is to disseminate real, research-based measures and tools to individuals who are seeking to increase their well-being. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=measurement" title="measurement">measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=psychometrics" title=" psychometrics"> psychometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20validation" title=" test validation"> test validation</a>, <a href="https://publications.waset.org/abstracts/search?q=well-Being" title=" well-Being"> well-Being</a> </p> <a href="https://publications.waset.org/abstracts/139083/psychometric-properties-of-several-new-positive-psychology-measures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139083.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">188</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> Empirical Analysis of the Effect of Cloud Movement in a Basic Off-Grid Photovoltaic System: Case Study Using Transient Response of DC-DC Converters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asowata%20Osamede">Asowata Osamede</a>, <a href="https://publications.waset.org/abstracts/search?q=Christo%20Pienaar"> Christo Pienaar</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Bekker"> Johan Bekker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mismatch in electrical energy (power) or outage from commercial providers, in general, does not promote development to the public and private sector, these basically limit the development of industries. The necessity for a well-structured photovoltaic (PV) system is of importance for an efficient and cost-effective monitoring system. The major renewable energy potential on earth is provided from solar radiation and solar photovoltaics (PV) are considered a promising technological solution to support the global transformation to a low-carbon economy and reduction on the dependence on fossil fuels. Solar arrays which consist of various PV module should be operated at the maximum power point in order to reduce the overall cost of the system. So power regulation and conditioning circuits should be incorporated in the set-up of a PV system. Power regulation circuits used in PV systems include maximum power point trackers, DC-DC converters and solar chargers. Inappropriate choice of power conditioning device in a basic off-grid PV system can attribute to power loss, hence the need for a right choice of power conditioning device to be coupled with the system of the essence. This paper presents the design and implementation of a power conditioning devices in order to improve the overall yield from the availability of solar energy and the system’s total efficiency. The power conditioning devices taken into consideration in the project includes the Buck and Boost DC-DC converters as well as solar chargers with MPPT. A logging interface circuit (LIC) is designed and employed into the system. The LIC is designed on a printed circuit board. It basically has DC current signalling sensors, specifically the LTS 6-NP. The LIC is consequently required to program the voltages in the system (these include the PV voltage and the power conditioning device voltage). The voltage is structured in such a way that it can be accommodated by the data logger. Preliminary results which include availability of power as well as power loss in the system and efficiency will be presented and this would be used to draw the final conclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tilt%20and%20orientation%20angles" title="tilt and orientation angles">tilt and orientation angles</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20chargers" title=" solar chargers"> solar chargers</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20panels" title=" PV panels"> PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20devices" title=" storage devices"> storage devices</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20solar%20radiation" title=" direct solar radiation"> direct solar radiation</a> </p> <a href="https://publications.waset.org/abstracts/98764/empirical-analysis-of-the-effect-of-cloud-movement-in-a-basic-off-grid-photovoltaic-system-case-study-using-transient-response-of-dc-dc-converters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98764.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">135</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> Exposure to Nature: An Underutilized Component of Student Mental Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeremy%20Bekker">Jeremy Bekker</a>, <a href="https://publications.waset.org/abstracts/search?q=Guy%20%20Salazar"> Guy Salazar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Nature-exposure interventions on university campuses may serve as an effective addition to overburdened counseling and student support centers. Nature-exposure interventions can work as a preventative well-being enhancement measure on campuses, which can be used adjacently with existing health resources. Specifically, this paper analyzes how spending time in nature impacts psychological well-being, cognitive functioning, and physical health. The poster covers the core findings and recommendations of this paper, which has been previously published in the BYU undergraduate psychology journal Intuition. Research Goals and Method: The goal of this paper was to outline the potential benefits of nature exposure for students’ physical health, mental well-being, and academic success. Another objective of this paper was to outline potential research-based interventions that use campus green spaces to improve student outcomes. Given that the core objective of this paper was to identify and establish research-based nature exposure interventions that could be used on college campuses, a broad literature review focused on these areas. Specifically, the databases Scopus and PsycINFO were used to screen for research focused on psychological well-being, physical health, cognitive functioning, and nature exposure interventions. Outcomes: Nature exposure has been shown to help increase positive affect, life satisfaction, happiness, coping ability and subjective well-being. Further, nature exposure has been shown to decrease negative affect, lower mental distress, reduce cognitive load, and decrease negative psychological symptoms. Finally, nature exposure has been shown to lead to better physical health. Findings and Recommendations: Potential interventions include adding green space to university buildings and grounds, dedicating already natural environments as nature restoration areas, and providing means for outdoor excursions. Potential limitations and suggested areas for future research are also addressed. Many campuses already contain green spaces, defined as any part of an environment that is predominately made of natural elements, and these green spaces comprise an untapped resource that is relatively cheap and simple. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nature%20exposure" title="nature exposure">nature exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=preventative%20care" title=" preventative care"> preventative care</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20mental%20health" title=" undergraduate mental health"> undergraduate mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=well-being%20intervention" title=" well-being intervention"> well-being intervention</a> </p> <a href="https://publications.waset.org/abstracts/139012/exposure-to-nature-an-underutilized-component-of-student-mental-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139012.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">214</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> Switching of Series-Parallel Connected Modules in an Array for Partially Shaded Conditions in a Pollution Intensive Area Using High Powered MOSFETs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osamede%20Asowata">Osamede Asowata</a>, <a href="https://publications.waset.org/abstracts/search?q=Christo%20Pienaar"> Christo Pienaar</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Bekker"> Johan Bekker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Photovoltaic (PV) modules may become a trend for future PV systems because of their greater flexibility in distributed system expansion, easier installation due to their nature, and higher system-level energy harnessing capabilities under shaded or PV manufacturing mismatch conditions. This is as compared to the single or multi-string inverters. Novel residential scale PV arrays are commonly connected to the grid by a single DC–AC inverter connected to a series, parallel or series-parallel string of PV panels, or many small DC–AC inverters which connect one or two panels directly to the AC grid. With an increasing worldwide interest in sustainable energy production and use, there is renewed focus on the power electronic converter interface for DC energy sources. Three specific examples of such DC energy sources that will have a role in distributed generation and sustainable energy systems are the photovoltaic (PV) panel, the fuel cell stack, and batteries of various chemistries. A high-efficiency inverter using Metal Oxide Semiconductor Field-Effect Transistors (MOSFETs) for all active switches is presented for a non-isolated photovoltaic and AC-module applications. The proposed configuration features a high efficiency over a wide load range, low ground leakage current and low-output AC-current distortion with no need for split capacitors. The detailed power stage operating principles, pulse width modulation scheme, multilevel bootstrap power supply, and integrated gate drivers for the proposed inverter is described. Experimental results of a hardware prototype, show that not only are MOSFET efficient in the system, it also shows that the ground leakage current issues are alleviated in the proposed inverter and also a 98 % maximum associated driver circuit is achieved. This, in turn, provides the need for a possible photovoltaic panel switching technique. This will help to reduce the effect of cloud movements as well as improve the overall efficiency of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grid%20connected%20photovoltaic%20%28PV%29" title="grid connected photovoltaic (PV)">grid connected photovoltaic (PV)</a>, <a href="https://publications.waset.org/abstracts/search?q=Matlab%20efficiency%20simulation" title=" Matlab efficiency simulation"> Matlab efficiency simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20power%20point%20tracking%20%28MPPT%29" title=" maximum power point tracking (MPPT)"> maximum power point tracking (MPPT)</a>, <a href="https://publications.waset.org/abstracts/search?q=module%20integrated%20converters%20%28MICs%29" title=" module integrated converters (MICs)"> module integrated converters (MICs)</a>, <a href="https://publications.waset.org/abstracts/search?q=multilevel%20converter" title=" multilevel converter"> multilevel converter</a>, <a href="https://publications.waset.org/abstracts/search?q=series%20connected%20converter" title=" series connected converter"> series connected converter</a> </p> <a href="https://publications.waset.org/abstracts/107062/switching-of-series-parallel-connected-modules-in-an-array-for-partially-shaded-conditions-in-a-pollution-intensive-area-using-high-powered-mosfets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107062.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">127</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">1</span> Disseminating Positive Psychology Resources Online: Current Research and Future Directions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Warren%20Jared">Warren Jared</a>, <a href="https://publications.waset.org/abstracts/search?q=Bekker%20Jeremy"> Bekker Jeremy</a>, <a href="https://publications.waset.org/abstracts/search?q=Salazar%20Guy"> Salazar Guy</a>, <a href="https://publications.waset.org/abstracts/search?q=Jackman%20Katelyn"> Jackman Katelyn</a>, <a href="https://publications.waset.org/abstracts/search?q=Linford%20Lauren"> Linford Lauren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Positive Psychology research has burgeoned in the past 20 years; however, relatively few evidence-based resources to cultivate positive psychology skills are widely available to the general public. The positive psychology resources at www.mybestself101.org were developed to assist individuals in cultivating well-being using a variety of techniques, including gratitude, purpose, mindfulness, self-compassion, savoring, personal growth, and supportive relationships. These resources are empirically based and are built to be accessible to a broad audience. Key Objectives: This presentation highlights results from two recent randomized intervention studies of specific MBS101 learning modules. A key objective of this research is to empirically assess the efficacy and usability of these online resources. Another objective of this research is to encourage the broad dissemination of online positive psychology resources; thus, recommendations for further research and dissemination will be discussed. Methods: In both interventions, we recruited adult participants using social media advertisements. The participants completed several well-being and positive psychology construct-specific measures (savoring and self-compassion measures) at baseline and post-intervention. Participants in the experimental condition were also given a feedback questionnaire to gather qualitative data on how participants viewed the modules. Participants in the self-compassion study were randomly split between an experimental group, who received the treatment, and a control group, who were placed on a waitlist. There was no control group for the savoring study. Participants were instructed to read content on the module and practice savoring or self-compassion strategies listed in the module for a minimum of twenty minutes a day for 21 days. The intervention was semi-structured, as participants were free to choose which module activities they would complete from a menu of research-based strategies. Participants tracked which activities they completed and how long they spent on the modules each day. Results: In the savoring study, participants increased in savoring ability as indicated by multiple measures. In addition, participants increased in well-being from pre- to post-treatment. In the self-compassion study, repeated measures mixed model analyses revealed that compared to waitlist controls, participants who used the MBS101 self-compassion module experienced significant improvements in self-compassion, well-being, and body image with effect sizes ranging from medium to large. Attrition was 10.5% for the self-compassion study and 71% for the savoring study. Overall, participants indicated that the modules were generally helpful, and they particularly appreciated the specific strategy menus. Participants requested more structured course activities, more interactive content, and more practice activities overall. Recommendations: Mybestself101.org is an applied positive psychology research program that shows promise as a model for effectively disseminating evidence-based positive psychology resources that are both engaging and easily accessible. Considerable research is still needed, both to test the efficacy and usability of the modules currently available and to improve them based on participant feedback. Feedback received from participants in the randomized controlled trial led to the development of an expanded, 30-day online course called The Gift of Self-Compassion and an online mindfulness course currently in development called Mindfulness For Humans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=positive%20psychology"
