The demand and supply of secondary school teachers in the Western CapeAyuk, Emmanuel Enow January 2012 (has links)
Thesis submitted in fulfillment of the requirement for the degree
Master of Education
in the Faculty of Education and Social Science
at the Cape Peninsula University of Technology, 2012 / Education has become an area of concern both in South Africa and the rest of the world. As a result there has been an increase of about one per cent on the average number of learners in South Africa schools (Collin, 2005), especially with the ‘education for all’ policy. Learner increase requires large numbers of teachers because they play a critical role in achieving the post-apartheid transformation and development agenda (Asmal, 1999). However, there are many disturbing reports that point towards large numbers of teachers leaving the education profession in both primary and secondary sectors. Many factors have rendered education an area of distress both in the Western Cape, South Africa and elsewhere in the world today. One of these factors is the mismatch between demand and supply of teachers which is arguably exacerbated by shortage of teachers.
The aim of this study is to (i) uncover factors that influence demand, supply and shortages of teachers among a select Western Cape Secondary Schools in order to (ii) primarily explore mechanisms and strategies that the selected schools employ for combating teacher demands, supply and shortages. The question following from these aims is: “How do some secondary schools in the Western Cape manage the tensions created by demand, supply and shortages of teachers?”
The study employs the qualitative research method that has utilised an exploratory research design to meet the research objectives. Secondary school teachers, principals, ex-secondary school teachers and deans/directors of schools/faculties of education make up the target population for this study. The sample constituted thirty participants that were purposefully and conveniently selected.
The finding in the study reveals that teacher demand and supply in the Western Cape is influenced by similar factors that occur elsewhere in the world. However the schools employ many ways to deal with teacher shortages, some of which are preventative or curative of the problem of teacher shortages. What is worth-noting is that since public schools in Western Cape are owned and funded by the provincial government, principals are limited in what they can do as most of the strategies require a high level of monetary commitment.

Get Legitimate: Achievements Promote Recovery from Addiction via Non-Addict IdentityCrutchfield, Daniel 01 January 2018 (has links)
Abstract
Despite decades of research, over 400 million people around the globe suffer from substance abuse and only 10% to 43% maintain abstinence after treatment. Social support, spirituality, self-regulation, and locus of control have all been examined for their efficacy and relationship with successful abstinence outcomes. Conceptually, educational/vocational achievement is believed to contribute to reforming an identity divorced from the previous lifestyle of active addiction. Educational and Vocational achievements as proxies for non-addict identity have only been investigated sporadically. The present study seeks to establish a quantitative link between successful long-term recovery and these types of goal-oriented achievements. A survey was administered to 195 participants in recovery and results showed that those who have achieved an advanced certification, license, or degree since getting clean report almost twice as must clean time as those who did not. Multiple regression revealed that educational/vocational achievement was a significant predictor and the overall model accounted for 49% of the variance in length of abstinence. These findings expose the importance of a neglected component of research in recovery from addiction. Implications include greater emphasis on vocational rehabilitation in recovery and future research should aim to examine and refine this concept further.

Putting the “Gay” in Gamers: Increasing Identification with Homosexuals Through Video GamesOlah, Matthew D. 01 January 2018 (has links)
Priming out-groups and taking the perspective of out-group members increases implicit and explicit identification with out-groups. Because the popularity of video games has increased dramatically over the past few decades and they have become an influential form of media, the current study investigated video games as another potential strategy to increase identification with and reduce prejudice against out-groups. Specifically, I investigated how manipulating the sexual orientation of the video game character participants used influenced implicit and explicit identification with homosexuals and implicit and explicit prejudice against homosexuals. Additionally, I investigated whether implicit and explicit identification with homosexuals would mediate the impact of video games on prejudice. Though I recruited enough participants to detect a medium effect size (169 participants in the final analyses), pre-registered analyses (osf.io/ynaw7) indicated that the sexual orientation of a video game character did not influence identification with or prejudice against homosexuals. Exploratory analyses demonstrated that among participants that identified with the video game character and played as a Gay character had increased explicit identification with and reduced prejudice against homosexuals. The possibility that increasing the strength of the manipulation by having participants play the game for multiple sessions, customize characters, and incorporating storytelling into the game are discussed.

Dermoscopy : An Evidence-Based Approach for the Early Detection of MelanomaArmstrong, Angela 01 January 2011 (has links)
The purpose of this project was to evaluate the effectiveness of a practice-based dermoscopy training program for dermatology healthcare providers in order to improve their technique of performing clinical skin exams for the early detection of melanomas. The overall incidence of melanoma continues to rise. More than 75% of all skin cancer deaths are from melanoma. Advanced melanoma spreads to lymph nodes and internal organs and can result in death. One American dies from melanoma almost every hour (American Cancer Society [ACS], 2009). Early diagnosis and excision are essential to reduce morbidity and to improve patient survival. This one-group before-and-after study design utilized a convenience sample of three dermatology healthcare providers (DHPs). The primary investigator conducted a retrospective review of the pathology logs for each provider. The time frame for the review was a three-month period in 2010, which represented the same time frame that the study was conducted in 2011. The DHPs participated in a four-hour training workshop that included pattern analysis recognition using dermoscopy. Following the workshop, each DHP was given a DermLite 3Gen DL100 to use in practice when performing clinical skin examinations. All DHPs completed a data collection sheet to document their pattern of decision making with and without a DermLite. The outcome of interest was the use of dermoscopy by DHPs to demonstrate an increased detection of melanoma when compared to naked-eye examination. The outcome was evaluated 12 weeks postworkshop training. There were 120 evaluations made with the DermLite as compared to the naked eye. The overall agreement was 0.52, AC1 coefficient (95% CI) was 0.36 (0.30, 0.42), p < .001, and kappa coefficient (95% CI) was 0.27 (0.20, 0.43), p < .001. Overall, the risk of lesion under exam being suspicion for skin cancer was higher on 27.5% (33 out of 120) of the evaluations and lower on 20.8% (25 out of 120) evaluations. The risk of lesion was evaluated the same on 51.7% (62 out of 120) of the evaluations. This is an indication of “Poor” agreement between the two methods. The diagnosis and disposition made using DermLite compared to naked-eye results for both coefficients provided an “Intermediate to Good” agreement between the two methods in assigning diagnosis and disposition. This indicates that there is no difference between DermLite and naked-eye evaluations. More studies are needed in order to provide better evidence on the value of dermoscopy in clinical practice at the Dermatology and Laser Center. Future projects should be more explicit regarding the methods used and lesion selection in order to better understand the benefits of dermoscopy.

Cross-Cultural Study of the Predictors of Learning in Children Ages 11-15 Years OldWilliams, Nadina Melina 01 January 2018 (has links)
Academic achievement is deemed a significant indicator for a successful future. Cognitive ability, home environment, and metacognition are among the many factors research has posited to contribute to academic achievement and later success (Alloway & Alloway, 2010; Bradley & Caldwell, 1984, Veenman, Wilhelm, & Beishuizen, 2004). The present study examines the relation between cognitive ability (working memory (WM) and nonverbal ability), metacognitive awareness, implicit theories of IQ, home environment (socioeconomic status (SES), home life, and parental involvement in homework), and learning outcomes (grades) in two distinct sample populations. The study used a sample of 11-15-year-olds and their parents from two high schools in Carriacou, Grenada (n=50) and Lakeshore Middle School in Florida (n=38). A stepwise regression revealed that cognitive ability, implicit theories of IQ, and home environment predicted overall grades of the Grenada sample. Several differences between the two cultures emerged including what predicted their implicit theories of IQ. The present study will benefit the educational community, as the findings could provide new insight into how students’ cognitive ability, implicit theories of IQ, and home life influence learning outcomes in a developed and developing population. The practical implications suggest more effective culturally responsive educational programs for students based on their learning style and learning needs. The present study has significance with reference to Grenada, in that because of little to no research available investigating this topic it will provide a basis for subsequent research to occur.

Treatment Analysis of a Captive Male Jaguar (Panthera onca)Morris, Megan Colleen 01 January 2018 (has links)
Large carnivores in human care have been reported to engage in stereotypic behaviors. Such behavior is thought to be correlated with high stress levels, in part, due to captive environments limiting opportunities for functional consequences and environmental stimuli. Moreover, there are several arguments stating that stereotypic behaviors can be indicative of poor welfare, as they can often have severe negative emotional and physical effects on the animal. The first portion of this study included a five-phase treatment analysis which evaluated whether environmental manipulations decrease the frequency of stereotypic behaviors including pacing, over-grooming and tail-sucking exhibited by a single male jaguar housed at Jacksonville Zoo and Gardens. The aim of the present study was to evaluate possible environmental variables that were reported by staff as likely variables maintaining or promoting stereotypic behavior. Data collection occurred during a 10-week evaluation and followed an ABCAD reversal design. Both behavioral data and fecal glucocorticoid metabolite levels were analyzed. The second portion of this analysis included a multi-institutional survey to assess the prevalence of the stereotypic behaviors exhibited by zoo-housed jaguars in North American AZA-accredited institutions. Results from the behavioral assessment revealed a decrease in stereotypic behaviors with the implementation of treatment conditions. Hormone analyses revealed that stereotypic pacing is not presently correlated with higher stress levels for this animal. Finally, survey results revealed that a significant portion of the North American jaguar population engages in stereotypic behaviors. Further analyses are necessary to identify potential patterns or environmental predictors for the development of stereotypic behaviors.

Pokémon Go as a Positive Virtual Reality Game: Promoting Cognitive, Affective, and Empathic BenefitsCarpenter, Rachel 01 January 2018 (has links)
Video game popularity and time playing in children, adolescents, and adults is steadily increasing due to heightened accessibility, advanced technological game design, and a rising sedentary lifestyle among Americans. The advent of exergames and virtual reality paradigms has led to a new wave of mobile video games that can be played anywhere, involve the combination of mobility and gaming, and may be used to improve cognition, affect, and perhaps empathy. The aim of the present study was to examine if the exergame Pokémon Go would improve visual and verbal working memory, attention, positive and negative affect, and empathy. Additionally, the current study is an extension of seminal research that discovered being in nature alone has positive effects on working memory and affect. Participants (N = 62) from a Florida University were assessed on the Alloway Working Memory Assessment (AWMA), the Positive and Negative Affect Schedule (PANAS), and the Interpersonal Reactivity Index (IRI) before and after playing Pokémon Go outdoors around the most natural parts of the campus (e.g., ponds, dense foliage). The participants then returned several days later, completed the assessments, and spent time outdoors not playing. The study was counterbalanced over the course of a year to control for seasonal differences. Main findings included increased verbal working memory scores and decreased negative affect after playing Pokémon Go with no changes in empathy. The results have important implications for those interested in using Pokémon Go to improve working memory and decrease stress and negative affect in adult populations.

Impressions of a Female Political Candidate Based on Political Party AffiliationVeilleux, Candice J. 01 January 2018 (has links)
There is a gender gap in United States politics; men are over represented, and prioritize issues/policies differently compared with women. Stereotypes may be associated depending on group memberships. Stereotypes of men (competent) are consistent and stereotypes of women (warm) are inconsistent with politicians (competent). I examined stereotypes of major/non-major political parties, and how party affiliation affects whether stereotypes about men/male politicians/women/female politicians predict female politicians’ traits. Stereotype valence ascribed to political parties is important because people vote for a positively viewed party/representative. I assessed the strength and valence of stereotypes associated with political parties, and found major parties were viewed more positively than non-major parties, and the Democratic and Republican parties were viewed more positively than the Independent Party (Study 1). I found warmth and competence attributes ascribed to women/female politicians/men/male politicians predicted Karen Johnson’s warmth and competence depending on whether Karen Johnson was a major or non-major party candidate. When men/male politicians were perceived as competent Karen Johnson was perceived as competent, but no relationship between men/male politicians’ warmth and Karen Johnson’s warmth emerged. When women/female politicians were perceived as warm/competent, Karen Johnson was perceived as warm/competent. As a major candidate, Karen Johnson was perceived as warm/competent when women/female politicians were perceived as warm/competent. However, when Karen Johnson was a non-major candidate, there was no relationship between women’s competence and Karen Johnson’s competence, and when women/female politicians were perceived as warm, Karen Johnson was perceived as warm (Study 2). Women in office and members of multiple social groups are discussed.

Hard Copy versus #Hashtag: Examining the Channels of Terrorist PropagandaCopello, Evan 01 January 2018 (has links)
In recent years, terrorism and radicalization has been a consistent issue that many countries have faced. The Islamic State of Iraq and Syria (ISIS) has been the most recent in a long trail of organizations that have sought to strike terror against the western world. However, ISIS is distinguished from other groups, like Al-Qaeda, in that ISIS supports a complex propaganda machine. Although ISIS is not the first organization to use the social media platform, they are the first to use it with such diversity. The two main channels that ISIS uses to spread their propaganda messages are through social media sites such as Twitter and through online journals such as the Dabiq. Recent research has attempted to determine how recruitment messages are being received and which messages trigger recruitment. It is the goal of this paper to determine which messages are salient, and the psychological constructs that support them. By coding messages for appeals to identity, need for cognitive closure, time pressure, and appeals to ideology, the researchers expect that the two main channels of ISIS propaganda differ in their messages. We hypothesize that Twitter messages will be targeted towards novice ISIS sympathizers, whereas the Dabiq will be focused on already-radicalized individuals who have moved past the introduction of the radical ideology.
