[pt] Práticas empreendedoras motivadas por propósitos sociais e ambientais têm ganhado reconhecimento mundial. No entanto, ainda existem muitas lacunas no conhecimento científico a respeito desse fenômeno. Esta tese investiga atributos e processos de liderança que possibilitam os empreendimentos sociais a serem efetivos. Inclui dois ensaios autônomos que investigam empiricamente a liderança em empreendimentos sociais e o processo pelo qual ela permite inovações sociais. A questão de pesquisa do primeiro estudo está relacionada a quais características, comportamentos e habilidades de liderança são essenciais para que os líderes de empreendimentos sociais alcancem seus objetivos de negócios. Assim, uma pesquisa qualitativa com base no protocolo metodológico da Grounded Theory foi realizada. Foram entrevistados 36 atores - líderes de organizações sociais e seus stakeholders. Os resultados revelaram oito atributos essenciais dos líderes de empreendimentos sociais: impulso para causar impacto, integridade moral inabalável, comunicação centrada no outro, postura relacional construtiva, desenvolvimento da equipe, resolução co-criativa de problemas, desenvolvimento de redes estratégicas e compromisso com alta qualidade da entrega. Essas descobertas sugerem que uma perspectiva clássica de liderança sozinha não pode abranger totalmente todos os atributos essenciais da liderança em empreendimentos sociais. A questão de pesquisa do segundo estudo está relacionada a quais processos psicossociais habilitados por líderes de empreendimentos sociais promovem a criatividade e a inovação de suas equipes. Assim, foi realizada uma pesquisa quantitativa, no nível de análise das equipes, para verificar os mecanismos pelos quais a liderança servidora e empoderadora possibilitam a criatividade e a inovação das equipes em empreendimentos sociais. A pesquisa foi realizada com uma amostra de 41 líderes e 73 colaboradores de organizações socioambientais. As hipóteses foram avaliadas estatisticamente por meio da modelagem de equações estruturais (Partial Least Squares - PLS), utilizando o software SmartPLS 3.0. Todas as hipóteses foram confirmadas, exceto uma. A liderança servidora influencia positivamente a identidade e o comprometimento da equipe. No entanto, a conexão desses processos com a criatividade não foi estabelecida. A liderança empoderadora influencia positivamente a ampliação de fronteiras da equipe e as suas capacidades dinâmicas, que foram associadas à criatividade da equipe e à inovação em empreendimentos sociais. Essas descobertas são uma contribuição única para a literatura e possibilitam um entendimento mais profundo de quais processos de liderança são necessários para gerar inovações sociais para resolver problemas socioambientais. Ambos os estudos avançam o conhecimento sobre liderança e seu papel nos empreendimentos sociais. / [en] Entrepreneurial practices motivated by social and environmental purposes have gained worldwide recognition. Nevertheless, there are still many gaps in scientific knowledge regarding this phenomenon. This thesis investigates leadership attributes and processes that enable social endeavors. It encompasses two stand-alone essays that empirically investigate social venture leadership and the process through which it allows social innovations. Essay one research question concerned which characteristics, behaviors, and leadership skills are essential for social venture leaders to reach their business objectives. A qualitative research was conducted based on the Grounded Theory methodological protocol. Thirty-six actors were interviewed – social organizations leaders and their stakeholders. The results unveil eight essential attributes of social venture leaders: drive to cause impact, unswerving moral integrity, other-centered communication, constructive relational stance, team empowerment, co-creative problem solving, strategic network development, and high-quality delivery commitment. These findings suggest that one classic leadership perspective alone cannot fully encompass all the essential attributes of social venture leadership. Essay two research question concerned which psychosocial processes enabled by social venture leaders promote team creativity and innovation. A quantitative research was conducted, focusing on the team level of analyses, to verify the mechanisms through which servant and empowering leadership enable team creativity and team innovation in social ventures. A survey was conducted with a sample of 41 leaders and 73 team members from socioenvironmental organizations. The hypotheses were statistically evaluated through Partial Least Squares (PLS) structural equations modeling, using the SmartPLS 3.0 software. All hypotheses were confirmed but one. Servant leadership positively influences team identity and team commitment. However, the connection between these processes with creativity was not established. Empowering leadership positively influences team boundary spanning and team dynamic capabilities, which were associated with team creativity and innovation in social ventures. These findings are a unique contribution to the literature and contribute to a deeper understanding of which leadership processes are necessary to bring about social innovations to solve socio-environmental problems. Both studies advance knowledge on leadership and its role in social ventures.

[pt] Mais do que um ambiente de aprendizagem acadêmica, a escola é também espaço onde as e os jovens se desenvolvem comportamental, emocional e cognitivamente e estabelecem relacionamentos sociais positivos. Atitudes preconceituosas, como a homofobia e a misoginia, vão de encontro com os objetivos educacionais e impactam negativamente no aspecto relacional que compõe o clima escolar. A presente pesquisa busca compreender este impacto através de um estudo sobre as relações existentes entre climas escolares distintos com ambientes menos ou mais preconceituosos em relação à diversidade sexual e de gênero. Para cumprir estes objetivos, traçamos um desenho de investigação quantitativo a partir das respostas de estudantes a dois questionários. O primeiro, inserido em uma pesquisa maior sobre preconceito, forneceu dados sobre as atitudes contra a diversidade sexual e de gênero na visão de estudantes do sétimo ano de dez escolas públicas localizadas no município do Rio de Janeiro. A partir destes dados, selecionamos duas escolas com posicionamentos distintos, a Escola Iracema e a Escola Hora da Estrela, e aplicamos um segundo questionário, dessa vez voltado para todo o segundo segmento do Ensino Fundamental, com questões acerca do clima da escola, além de mais itens sobre preconceito em relação à diversidade sexual e de gênero. A partir da elaboração de índices, observamos que apesar de estarem geograficamente próximas e possuírem um corpo discente social e culturalmente parecido, oriundo dos mesmos bairros do entorno, as duas escolas possuem diferenças marcadamente significativas em relação ao clima e às visões e atitudes preconceituosas: as alunas e os alunos da Escola Iracema percebem um clima escolar menos positivo e indicam apresentar pensamentos mais preconceituosos contra a diversidade sexual e de gênero do que as e os estudantes da Escola Hora da Estrela. Observamos que as visões preconceituosas quanto à diversidade sexual e de gênero das e dos estudantes se associam positivamente com o bom relacionamento com seus pares e negativamente com: (i) a percepção do respeito à diversidade pela comunidade escolar; (ii) a compreensão do papel da gestão na resolução dos conflitos escolares; (iii) o comportamento e os sentimentos de engajamento e pertencimento na escola e (iv) a violência sofrida por bullying. Conclui-se que um ambiente escolar marcado por um clima mais positivo pode apresentar, ao mesmo tempo, estudantes menos misóginos e homofóbicos. / [en] More than an academic learning environment, the school is also a place where young people develop behaviorally, emotionally and cognitively and form positive social relationships. Prejudiced attitudes such as homophobia and misogyny are opposed to educational goals and negatively impact the school climate relational aspect. This research aimed to understand this impact through the relationships between different school climates with less or more prejudiced environments in terms to sexual and gender diversity. To fulfill these goals, we draw a quantitative research design from student responses to two surveys. The first, integrating a larger research on prejudice, provided data on attitudes against sexual and gender diversity in the view of 7th grade students from ten Rio de Janeiro city public schools. From these data, we selected two schools with different positions, Iracema School and Hora da Estrela School, and applied a second questionnaire, this time focused on the entire second segment of elementary school, with questions about the school climate, and more items on prejudice against sexual and gender diversity. Despite geographically close and with socially and culturally similar student configuration, coming from the same neighborhoods, the two schools have markedly significant differences in relation to its school climate and prejudiced views and attitudes: from the established indices, it is concluded that Iracema School students perceive a less positive school climate whereas indicate more prejudiced thoughts against sexual and gender diversity than Hora da Estrela School students. We observed that the prejudiced students’ views regarding sexual and gender diversity are positively associated with good peer relationships and negatively associated with: (i) the perception of respect for diversity by the school community; (ii) the school management role on conflict resolution; (iii) the behavior and the feelings of engagement and belonging at school and (iv) the peer victimization through bullying. It is concluded that a school environment marked by a more positive climate can have, at the same time, less misogynist and homophobic students.

Background: As businesses started to recognize the potential of live streaming platforms in reaching and engaging with their target audience, live streaming commerce (LSC) started to gain traction and popularity over the past few years. LSC, with its elements of time pressure, price promotion, and interaction, plays a significant role in influencing consumers’ impulsive buying behaviour. The live nature of these streams create a sense of urgency, making viewers feel like they need to act quickly before the opportunity is gone. Price promotions, such as limited-time discounts or exclusive deals, entice viewers to make impulsive purchases to take advantage of the savings. Moreover, the interactive aspect of live streaming allows viewers to ask questions and receive real-time responses, which enhances the overall shopping experience and can further stimulate impulsive buying. Purpose: The aim of this thesis is to investigate how Gen Z consumers’ impulsive buying behaviour of cosmetics through LSC is influenced by three factors, being; time pressure, price promotion, and interaction. As well as how emotions such as the feeling of urgency, the feeling of excitement, and perceived enjoyment could mediate this relationship. Methodology: A deductive research approach  and a quantitative method was selected and utilised for this research. To gather data, a self-completion questionnaire was developed in Google Forms, taking into consideration ethical and societal factors. A total of 312 valid responses were collected, which were then subjected to descriptive analysis, correlation analysis, reliability analysis, regression analysis, and mediation analysis.  Findings: The results of this research revealed that H2 and H3 were accepted, indicating that price promotion and interaction have a significant positive impact on Gen Z consumers’ impulsive buying behaviour in LSC. In the same vein, H1a, H2a, and H3a, i.e., the feeling of urgency, excitement, and perceived enjoyment were accepted. However, H1, measuring the influence of time pressure, was rejected.  Conclusion: This study concluded that price promotion (H2) and interaction (H3) have a positive influence on the impulsive buying behaviour of Generation Z consumers. However, time pressure (H1) was not found to have a significant impact. Additionally, the results indicate that the feeling of urgency (H1a) mediates the relationship between time pressure and impulsive buying behaviour, the feeling of excitement (H2a) mediates the relationship between price promotion and impulsive buying behaviour, and perceived enjoyment (H3a) mediates the relationship between interaction and impulsive buying behaviour among Gen Z consumers in Sweden.

The live music performance industry is growing tremendously in South Africa, with more and more international artists performing on our shores year after year. Competition is growing and various companies are beginning to identify this as a business opportunity to make money. However, managing live music performances is a complex task which involves managing various aspects (critical success factors) of the event in order to ensure that it is a success. Apart from this, visitors attend these performances hoping that their expectations will be exceeded and the performance is something which can be treasured and is worth remembering once everything is over. This is referred to as a memorable experience. In order to ensure a memorable visitor experience, it is essential for managers to be aware of what the visitors regard as important critical success factors. These are aspects that management can control and improve. Thus, the critical success factors should be implemented effectively in order to ensure that the event is memorable for visitors attending the live music performance. While various critical success factors are familiar to event organisers, they differ from event to event. Thus, the critical success factors of one event cannot be implemented at another with the same expectation of success. This is due to the heterogeneous groups of people who attend these events and who cannot be regarded as being the same, as each individual will have different expectations of the same event. Therefore, it is also important for the managers of live music performances to determine how the visitors to the different genre events regard the various critical success factors that are vital for a memorable experience. This is significant, as various music genres attract different attendees who each have their own expectations of a music genre and which may differ from those of visitors to other music genres. For example, the expectations for a memorable experience of individuals attending a classical live music performance will differ from individuals attending a rock or pop live music performance. In addition, it is also important for management to compare those critical success factors identified by the visitors to their own ideas of what is important for a successful event in order to identify any shortcomings. Thus, it was expedient to seek answers to the questions of what visitors to live music performances regard as important critical success factors as well as what the managers consider to be important for a memorable experience. Therefore, the purpose of this study was to determine the critical success factors for managing a memorable visitor experience at live music performances from both the demand and supply sides. The said factors were subsequently compared in order to establish whether any shortcomings exist. This thesis comprises three articles. Firstly, the research was conducted from a demand (visitors) side. Thus, the aim of Chapter 3 was to determine what attendees at live music performances regard as being critical success factors for different music genres so as to enhance memorable visitor experiences. Surveys were conducted at various genres of live music performances which included classical music (Il Divo), R&B (Usher), rock (Sting), blues (Michael Buble), pop (Roxette) and Afrikaans music (Steve Hofmeyr). A total of 4 110 questionnaires were administered and a general profile of the visitors in terms of the different genres was compiled. A factor analysis was subsequently performed in order to determine the critical success factors for all six genres. Thereafter, an Analysis of variance (ANOVA) was applied in order to compare the critical success factors of the various genres with one another. The results indicated significant statistical differences amongst the different music genres with regard to that which the visitors to the different live music performances regard as being important for a memorable visitor experience. Secondly, the research was conducted from a supply (managers) side and the objective of Chapter 4 was to determine what the managers consider to be important critical success factors in ensuring a memorable visitor experience at a live music performance. A qualitative research method, by means of interviews, was used to obtain the relevant information from the selected participants. All the data collected in the process were transcribed into text and presented in a narrative form. The six step method formulated by Cresswell (2009:185-189) for data analysis and interpretation was used to analyse the data. Four major themes emerged from the analysis where each theme was differentiated in terms of various categories and subcategories. This process contributed greatly towards gaining detailed information regarding the main purpose of organising a live music performance; identifying the aspects that managers consider to be important when organising a live music performance and those aspects that are important in pre-, during- and post-event planning phases as well as how managers define a memorable experience. Lastly, in Chapter 5 a comparison was performed between the demand and supply sides of live music performances in order to establish whether any differences exist amongst the aspects that management consider to be important compared to the critical success factors that the visitors regard as being important to achieve a memorable visitor experience. Both qualitative (supply side) and quantitative (demand side) research methods were implemented in this research. The results of the critical success factors drawn from the first and second articles were used to conduct this research. The results of both the demand and supply sides were subsequently compared with one another where significant differences had been identified. This was the first time that research was conducted from both the demand and supply sides within the live music performance environment. The results of this research contribute greatly to literature and to the music industry. In addition, this was also the first time that both a qualitative and a quantitative research method were applied in research conducted at live music performances and which were subsequently compared with one another. Determining the differences between the critical success factors identified contributes towards event specific education and information for current as well as future live music performance managers. Therefore, results of this research can be employed to educate and inform current and future managers in the live music performance industry regarding important aspects relating to the enhancement of the important critical success factors that contribute to a memorable experience when individuals attend a live music performance. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2014

Parental involvement (PI) greatly benefits learners of all ages. The implementation of a PI programme would provide an effective and affordable means to address the needs of learners in Swaziland. The purpose of this study was to develop a PI programme for urban primary education in Swaziland. The literature revealed that while comprehensive PI programmes are most effective, PI in learning activities in the home and an appropriate parenting style are particularly beneficial and correlate more closely with learning success than family background factors. Nevertheless, a relationship between family background factors and PI exists. Furthermore there are numerous barriers to PI. However, the most important determinant of PI is the effort of teachers to involve parents. PI is particularly important at senior primary level, the level at which PI drops off spontaneously. In order to gain a more complete understanding of PI in this community, which would form the basis for an effective PI programme, a combined quantitative and qualitative approach was undertaken. A parental questionnaire was used to test quantitatively the affects of family background factors on three measures of PI and to determine the ways in which parents were involved, their attitudes to the schools, and the schools' efforts to involve them. Teacher and parent interviews and focus discussions were conducted following a qualitative ethnographic approach. The integrated quantitative and qualitative findings revealed a low level of PI. As a result of a lack of relevant policy, Swazi teachers had very little understanding of PI or their role in establishing it. Thus, schools generally practiced Swap's Protective Model such that parents had very few opportunities, and little encouragement, to become involved. Consequently, parents did not fully appreciate the importance of their involvement and did not always choose to become involved. The study revealed a number of barriers that further interfered with their involvement. The implications of the findings were discussed and recommendations for a PI programme that harnesses the strengths and addresses the weaknesses of this community were made. In order to improve educational practice, recommendations targeted each role player and type of PI separately. / Educational Studies / D.Ed.(Psychology of Education)

Academic achievement in the context of the school necessarily involves a whole range of factors. The education system and schools in particular, have assumed the primacy of cognitive attributions in the learner over that of any other factors in the shaping and honing of individual academic achievement. However, the literature revealed that the learning process within the school environment feeds on a plethora of explanations for academic success or otherwise. Much work by researchers has focused on factors other than the cognitive, in an attempt to explain good or weak academic achievement. Certainly the separation of the cognitive from the affective in terms of achievement is impractical, as revealed by the literature. However the literature also contradicts received wisdom which suggests the omniscience of the cognitive as an explanatory tool for academic performance. This investigation focused on factors other than the cognitive in order to seek reasons for academic success. Three important affective factors were selected from the literature in order to ascertain whether these factors played a role in academic achievement or indeed if there was a relationship between these factors and scholastic success or otherwise. An empirical investigation was conducted which consisted primarily of a questionnaire for form four students in English classes. The questionnaire consisted of four sections with a total of 81 items. It was completed by 271 students attending five schools in Mutare Zimbabwe. Statistical analyses revealed that the affective factors attitudes towards English, self-concepts of academic ability and student perceptions of their teachers of English correlated significantly. The analyses also revealed that the selected factors took up 33% of the variance and that within that 33% the area in which students lived was the most important factor contributing to academic achievement whilst I.Q. and student self-concept of academic ability followed closely. The results of the literature study and the empirical investigation demonstrated that there are factors other than the cognitive which are important in terms of academic success in school As a result recommendations were made regarding school based programmes where the aim is to enhance affective factors and therefore achievement. / Educational Studies / D.Ed.
