One goal of music theory is to describe the resources of a pitch system. Traditionally, the study of pitch intervals was done using frequency ratios of the powers of small integers. Modern mathematical music theory offers an independent way of understanding the pitch system by considering intervals as transformations. This thesis takes advantage of the historical emergence of algebraic structures in musicology and, in the spirit of transformational theory, treats operations that form mathematical groups. Aspects of Neo-Riemannian theory are explored and developed, in particular the T/I and PLR groups as dual. Pitch class spaces, such as 12, can also be defined as torsors. In addition to surveying the group theoretical tools for music analysis, this thesis provides detailed proofs of many claims that are proposed but seldom supported.

Darbe buvo siekiama atskleisti darbuotojų įsipareigojimo, etinio klimato organizacijoje ir transformacinio vadovavimo stiliaus sąsajų ypatumus. Tyrime dalyvavo 208 įvairiose organizacijose dirbantys tiriamieji (71 vyras ir 136 moterys). Įsipareigojimas organizacijai buvo vertinamas R. T. Mowday, R. M. Steers ir L. W. Porter (1979) įsipareigojimo organizacijai klausimynu, vadovavimo stilius - GTL skale (autoriai Carless, Wearing ir Mann, 2000) bei etinis klimatas – Etiniu klimato klausimynu, sudarytu B. Victor ir J. B. Cullen (1987, 1988). Rezultatai parodė, jog vienintelis sociodemografinis veiksnys, kuriuo galima būtų prognozuoti darbuotojų įsipareigojimą organizacijai, yra darbuotojo pareigos. Nustatyta, kad vadovaujantį darbą dirbantys asmenys yra labiau įsipareigoję organizacijai bei savo vadovo stilių suvokia kaip labiau transformacinį nei nevadovaujantį darbą dirbantys darbuotojai. Tyrimo rezultatai neatskleidė kitų individualių sociodemografinių veiksnių (amžiaus, lyties, šeimyninės padėties, darbo stažo) ir organizacinių veiksnių (organizacijos dydžio, organizacijos darbo srities, viešo/ privataus organizacijos sektoriaus) ryšių su įsipareigojimu organizacijai bei suvokiamu transformaciniu vadovavimo stiliumi. Nustatyta, jog organizacijoje, kurioje vyrauja globos etinis klimatas, darbuotojai yra labiau įsipareigoję organizacijai negu organizacijoje, kurioje vyrauja instrumentinis etinis klimatas ar taisyklėmis, įstatymais ir profesiniais kodeksais paremtas etinis...

The organizational commitment was measured by Mowday, Steers and Porter (1979) Organizational Commitment Questionnaire, the transformational leadership style was assessed using GTL scale developed by Carless, Wearing and Mann (2000). Ethical Climate Questionnaire, constructed by Victor and Cullen (1987, 1988) was used to assess ethical climate. The results revealed that the only predictive socio-demographic factor of the organizational commitment was the position of the employee. It was found that leading employees were more committed to their organizations and assessed the style of their leader as more transformational than non-leading employees. The results did not reveal any other socio demographic factors (such as gender, age, marital status, experience) and organizational factors (such as size and type of organization, public/private sector within the organization operates) relationships with organizational commitment and transformational leadership. It was identified that the employees are more committed to the organization containing care ethical climate than to the organization containing instrumental ethical climate or climate based on rules, law and codes. The more employees perceive their leaders as... [to full text]

This study examines the relationship between supervisors’ transformational leadership behaviors and their work groups’ subsequent affective well-being and job satisfaction under specific moderating conditions (collective efficacy and perceptions of meaningful work). Longitudinal data from 42 work groups in a Canadian government organization was used to test the proposed relationships. Work groups’ collective efficacy has a significant moderating effect on the relationship between transformational leadership and positive group affective well-being. Specifically, groups with lower levels of collective efficacy exhibit a stronger relationship between transformational leadership behaviours and both affective well-being and job satisfaction.

The purpose of this study is to determine if transformational leadership styles of agriculture teachers in Jessamine County has an impact on successful transitions of program completers. To be more specific, the focus was to look at agriculture teachers at Jessamine Career and Technology Center (JCTC) to see if they exhibit components of transformational leadership. If so, does transformational leadership of those teachers assist students with successful transitions after graduation? Successful transition is deemed by the Kentucky Department of Education as students that seek post-secondary education, employed full-time or enlist in a branch of armed services. The population for this study consists of graduates from Jessamine County between the years of 2010-2012. All participants were program completers in the agriculture career major. All participants also meet the criteria of successfully transitioning. The participants in the study indicated agriculture teachers at JCTC did exhibit all components of transformational leadership. Participants also indicated transformational leadership utilized by the agriculture teachers assisted them in successfully transitioning after high school. Relationships between participants and agriculture teachers at JCTC were an indicator of why transformational leadership was a successful leadership style of the agriculture teachers.

Syfte: Verksamheten har ställda mål som de inte uppnår, därför har en omorganisation genomförts. Syftet med undersökningen är att få kunskap om hur mellancheferna beskriver sitt arbetssätt med att utveckla sin personal och hur omorganisationen har påverkat mellanchefernas arbete. Frågeställningar: Hur beskriver mellancheferna sitt arbete med att utveckla sin personal mot övergångar? Hur upplever mellancheferna implementeringen av omorganisationen och dess påverkan på övergångsarbetet? Metod: I vår studie används främst teorier som berör ledarskap och förändring. Vi har utgått från ett fenomenologiskt perspektiv och en kvalitativ metod med en abduktiv ansats. Sammanlagt har tretton intervjuer genomförts. Vi har utgått från semistrukturerade intervjuer med öppna frågor, med en intervjuguide som grund. Huvudresultat: Undersökningen har visat att individer vågar ta steget ut på arbetsmarknaden genom att de upplever egenmakt. Chefer behöver dock tid och resurser för att de skall kunna arbeta för att skapa egenmakt bland personalen. För att få motiverade medarbetare krävs det av ledarna att ha tydliga mål och uppmuntra. Genom delegering av makt till driftledare utvecklas individer i sin arbetsroll och tid frigörs. För att en omorganisation skall implementeras fullt ut krävs målstyrning, där ledning och mellanchefer tillsammans definierar de nya rollerna. / Purpose: The organization do not achieve the goals, therefore, a reorganization has taken place. Our purpose with this survey is to gain knowledge about how the managers describe their approach to developing the staff to venture out onto the labor market and how the reorganization has affected their work. Questions: How do you describe the managers' efforts to develop their staff to leave the organization? How managers experience the implementation of the reorganization and its impact on the transition process? Method: We ́ve used theories that involve leadership and change. We have used a phenomenological perspective and a qualitative method with an abductive approach. Thirteen interviews has been conducted. We have used semi-structured interviews with an interview guide as a basis. Results: Individuals venture out onto the labor market when they feel empowered, but managers need time for it to be possible. To get motivated employees, leaders need to encourage and have clear goals. By delegation of authority to employees, individuals develop in their role and time is released. Management by objectives is required for a reorganization to be fully implemented, where managers and middle managers together define the new roles.

The advent of democracy in South Africa in 1994 led to new areas of research interest, not least in the field of educational leadership and management (ELM). However, besides the Project on Postgraduate Education Research (PPER), not much research has been conducted to investigate the trends in research conducted by postgraduate students in South African universities. This study therefore aimed to contribute by investigating the trends in postgraduate research in ELM at a selected institution in the decade 1995-2004. Working in the interpretivist paradigm, the study employed an institutional case-study approach to conduct a study of 53 M.Ed. dissertations in the PPER database from the selected institution. The dissertations dealt with ELM topics. Statistical analysis on this dataset and content analyses of three selected dissertations were used to identify trends in education research at the selected institution. Robin Usher’s four concepts of con-text, pre-text, sub-text and inter-text were employed as a framework within which to interpret the findings. From the analysis it is evident that the first ten years of the democratic era in South Africa witnessed a change in the demographic profile of postgraduate research. The trends are that Black students completed more dissertations followed by Indian, White and Coloured students; there are more dissertations from males than females, although by the end of the decade the number of woman writing dissertations had increased significantly; research of ELM is mostly qualitative in approach and of small-scale studies; dissertation topics cover a range of five ELM areas of interest, with few authors exploring the con-text of ELM within the broader socio-political context of the decade under consideration. / M.Ed.

Adapting to change in a constantly changing environment is a challenge that organisations face on a daily basis. In order to stay competitive globally, the management of resistance to change becomes crucial. Research done on leadership reveals the very strong effect that leaders have on followers’ behaviours and attitudes and it is emphasized the role leadership plays in the implementation and supporting of change. The purpose of this dissertation is to determine whether a relationship between leadership and resistance to change exist within the higher education sector. The study obtains data of 75 participants within the faculty of engineering. The survey was done by means of a questionnaire. The statistical analyses included frequency analysis, descriptive statistics, reliability analysis, correlations, independent t-tests, Mann-Whitney tests, ANOVAs and Kruskal-Wallis tests. Results indicated that employees’ reactions toward change could be influenced by the type of leadership style present in the organisation, therefore it is necessary that the correct leadership style within an organisation cannot be underestimated. It could mean the difference between success and failure. For the purpose of this study, the researcher considered the scales of the Resistance to Change questionnaire sufficiently reliable, but further exploration of the scales and its adaptation to this context may be needed in future to enhance reliability measures. An important insight of this research is that, to be more effective in creating and supporting change within organisations, managers need to learn to recognise and understand resistance within them as well as in others. This research contributes to the already vast content of research on leadership and resistance to change and does so by being focused on studying these constructs under a unique set of circumstances. / Thesis (MBA)--North-West University, Potchefstroom Campus, 2013

The title of the research is “How mentorship is perceived to contribute to the well-being of an employee in an explosives manufacturing organisation”. This research was conducted within AEL Mining Services, an explosives manufacturing organisation that is part of the AECI group of companies. The object of the research was to gain a better understanding of the association between mentorship and well-being, based on how the experience is perceived by the employee that was either part or not part of such a program, be it formal or informal. During the literature study authors such as Keating (2012:91), Govender and Parumasur (2010:2) and Masango (2011:1) felt very strongly that mentorship begins on the day of birth and continues throughout one‟s entire life where competencies in the mentor role entail understanding self and others, communicating effectively and developing employees and it is clear that great leaders would not have achieved their full potential without effective mentoring. During the literature study it was also found that advantages as well as disadvantage are linked to mentorship, but that the advantages outweigh the disadvantages. Research identifies the need for sustainable development and although a variety of mentorship models exist that are currently used, it is evident that mentorship does have an impact on whoever is subjected to it. The study adopted a quantitative methodology, in which more than one questionnaire was utilised. Mentorship was identified as the independent variable and well-being as the dependent variable. For this study, the respondents were required to disclose geographical information concerning themselves and in addition to this, the Mental Health Continuum and General Health Questionnaire was utilised in order to determine the level of well-being as perceived by the respondents, based on mentorship or the lack thereof. The Statistical Consultation Services of the North-West University determined the statistical methods and procedures for the analyses of the research. Ellis and Steyn (2003:51-53) make it clear that in many cases it is important to know whether a relationship between two variables is practically significant. The research made use of triangulation where Gratton and Jones (2010:121) propose that triangulation can strengthen the validity of research, and is useful as a means to demonstrate trustworthiness in the analysis. Based on the results generated from the statistical analysis, the mentored group has a better overall state of health and psychological well-being than the non-mentored group. The deduction is thus made that with mentorship there is a significant difference in the overall well-being of an employee that was subjected to such a program. Recommendations were made regarding further research that needs to be conducted, in which a mentorship program is tailored for a specific company/organisation within the explosives manufacturing industry, then implemented and the results of it measured over a period of time. / PhD, North-West University, Potchefstroom Campus, 2014
