The purpose of the study was to investigate the relevance of School Management Training (SMT) to school practice; present an overview of SMT in Zimbabwe; and identify and analyse relevant SMT models to school headship. The research methods involved a literature study of primary and secondary sources, as well as an empirical situation analysis of SMT in Zimbabwe. The secondary sources comprised books, journals, research dissertations and theses. The primary sources comprised official circulars, course outlines of the B.Ed (EAPPS) degree programme and the Heads Training Support Programme (HTSP) modules. The knowledge drawn from these sources was the basis for developing appropriate models for SMT. The empirical situation analysis comprised the use of questionnaires and interviews to examine the content, typology, the modes of SMT in Zimbabwe, as provided by a sample of 218 randomly selected school heads in Bulawayo, Matabeleland North and South regions. Personal and group interviews were conducted with selected school heads. The findings revealed the following strengths of SMT in Zimbabwe: • Induction SMT is offered to newly-appointed school heads in order to inspire their confidence in leadership. • Various forms of continuing on-site SMT on-the-job training opportunities to school heads. • Whilst off-site SMT workshops inculcate skills from school headship expenence, SMT conferences and seminars run by heads' professional associations cater for SMT needs of school heads. Weaknesses of SMT in Zimbabwe exposed by the study involve: • Lack of SMT newsletters to encourage self-induction • Lack of institutional provision for the smooth co-ordination of SMT • Little involvement of university experts in non-formal SMT (iii) A tripartite collaborative SMT model which integrates self-development, university tuition and HTSP tuition is recommended. For the smooth operation of the model a dedicated institute for SMT is recommended. Any further research study, local or in the Southern African Development Community (SADC) region, should investigate the feasibility of a tripartite collaborative model and the dedicated institute in SMT / Educational Leadership and Management / D.Ed.

This study investigates the role of transformational leadership in influencing students’ outcomes in public secondary schools using Kuwait as a case study. The standard of academic achievement in Kuwait’s public schools has been declining over the years, which calls for a different type of leadership to transform these schools. It is argued in this thesis that there is merit in bringing in private sector business models to the public education sector in order to transform the sector and improve the schools’ outcomes. Furthermore, not much research has been undertaken on the paths through which transformational leadership influences public school outcomes in developing countries such as Kuwait. Following a critical review of leadership literature, a theoretical model for leadership that is transformational was conceptualised and this formed the basis of hypotheses formation and data collection. The thesis is thus original in its attempt to understand the paths through which school heads’ transformational leadership influence student’s outcomes in public secondary schools in a developing country (Kuwait). The study adopted a positivist ontology and objective epistemology and obtained data from 495 school heads and staff from 86 public secondary schools in Kuwait via a structured questionnaire. Confirmatory factor analysis (CFA) and structural equation models (SEM) tested the direct and indirect effects of school heads’ transformational leadership in influencing students’ outcomes the student “achievement” and the student “engagement” via several mediating variables including “school culture”, “class room condition” and “academic emphasis”. The analysis identified idealized influence (attributes) and idealized influence (behaviour) as the underlying dimensions of transformational leadership that directly and indirectly influences both student engagement and student achievement as the final outcome. The findings also confirmed differences between males and females in their leadership styles and subsequent influence on students’ achievement, and student engagement with the latter appearing to be better school heads. Therefore, two structure equation models were built to investigate the characteristics of each gender leadership style on the outcome variables. The findings also revealed that males’ leadership style has significant effect on student achievement but not student on engagement, while female leader ship style has significant effect on both student achievement and student engagement stronger than the males’ effect counterpart. Generally however, transformational leadership style has significant effect on both student achievement and student engagement. The study objectives were met and the study contributes to understanding the role of transformational leadership and its influence on staff and students’ achievement, from a developing country in the GCC. Managerial recommendations and suggestions for policy makers are made. Study limitations are highlighted leading to suggestions for further study.

Doctor of Philosophy / Department of Biological & Agricultural Engineering / Naiqian Zhang / One of precision agriculture researches currently focuses on the relationship between plant phenotype, genotype, and ambient environment, including critical investigations of a multi-sensor-integrated phenotyping platform and data mining technology for big data. This study examined the designs of two phenotyping platforms and developed machine vision (MV) technology to estimate wheat growth status and count wheat head. The GreenSeeker, an infrared thermometer (IRT), a web camera, and a global positioning system (GPS) receiver were integrated into one handheld phenotyping platform, named as Phenocorn. The Phenocorn allowed simultaneous collection of the normalized difference vegetative index (NDVI) and canopy temperature (CT) with precise assignment of all measurements to plot location by GPS data points. The Phenocorn was tested using a field trial of 10 historical and current elite wheat (Triticum aestivium) breeding lines at the International Maize and Wheat Improvement Center (CIMMYT) in Ciudad Obregon, Mexico, during the 2013 and 2014 growing seasons. Results showed that the NDVI data, PVC (percent vegetation coverage) data, and temperature data obtained by the handheld phenocorn could availably reflect the wheat growing status in the field, and the handheld phenocorn could be used as an instrument to do plant phenotyping information collection. This study also used the modular design method to design the mechanical structures of a robot-based phenotyping platform, named as Phenorobot. Its control system was based on a Controller Area Network (CAN bus). The basic function performances such as steering function, lifter load, and movement features were tested in the laboratory. Proposed design indicators were achieved, demonstrating its potential utilization for field experiments. Image acquisition is one of the main data collection methods for plant phenotyping research. The method for extracting plant phenotyping traits based on MV was explored in this research. Experiments for detecting the wheat development based on the images taken in the field were designed and carried out from March to June 2015, and a method based on color analysis to estimate percent vegetation coverage (PVC) of wheat was developed. A wheat growth model based on the PVC was used for the wheat growth status analysis. In addition, a wheat head counting method was developed and divided into three steps: wheat head image segmentation, leaf debris elimination, and wheat head counting. This paper proposes the first wheat head counting model (WCM) based on the pixels group measurement of wheat heads. Compared to the Joint Points Counting (JPC) method (Liu et al., 2014) and the Wheatear Shape Index (WSI) method (Frédéric et al., 2012), the WCM more accurately counted wheat heads from images taken in the experiments.

The purpose of this study is to discover if there exists a difference between the perceived roles and functions of intensive English program (IEP) directors and what they actually are. The study is a partial replication of Matthies (1983). A total of 46 subjects participated in a nation-wide survey which asked the respondents to rate the importance of functions and skills in good job performance and in self-assessment of ability. The findings indicated that IEP directors rate the activities associated with administration higher in importance than teaching skills, yet rate themselves better at teaching overall. Additionally, the respondents have more and higher degrees in Linguistics and Applied Linguistics than previously seen by Matthies (1983).

The aim of this study was to investigate the conditions that Heads of Department are facing when conducting Systematic Work Environment Management (SWEM) within psychosocial work environment at Umeå University. The study has focused on the obstacles and tools that Heads of Department are experiencing in their efforts to investigate, assess, and measures to reduce risks and follow up actions in the psychosocial work environment. To investigate this, I conducted semi-structured interviews with four Heads of Department and a Head of Unit at Umeå University. The interviews were recorded, transcribed and analysed. The result of the study is that dialogue and cooperation on different levels of the workplace seems to be the foundation of their SWEM within psychosocial work environment. A relationship-oriented leadership, good communication climate at the workplace, and various support functions are also important tools. Some of the obstacles that they experience are heavy workload, performance cultures, and sometimes lack of central support. SWEM also seems to be more time-consuming within psychosocial work environment than within the physical environment. It is not possible to draw any general conclusions from this study, but it has indicated several tracks that might be interesting to investigate further to improve conditions for the Heads of Department. For example, to further map their psychosocial environment, if the central support is perceived as sufficient and how to safeguard the local support from, for example, human resources specialists and work safety representatives.

The importance of preschool quality in Sweden is a subject of concern for preschool workers, researchers, parents and other stakeholders internationally. After the revision of the national preschool curriculum in 2010, the examination of the role of heads in outlining and maintaining quality has become a topic of concern, in particular regarding systematic quality work and the responsibilities of the heads in relation to this work. The purpose of this literature review is therefore to examine the extant research on how preschool heads in Sweden understand and work with the issue of quality in Early Childhood Education and Care. The research questions are: What is preschool quality, and how can it be assessed in the eyes of the head preschool teachers in Sweden? And, how do the heads fulfil their responsibilities inrelation to quality work in preschool? Four studies were reviewed and analyzed based on three criteria of measuring quality: structural,result,and processual. The results showed that the preschool heads had broad areas of measuring quality work, covering all three areas of quality. However, their practical quality work only covered some of these areas. Collaboration with staff, parents and other preschools wasmost commonly mentioned by the heads, as they are also problematised on their daily tasks in practice. Generally, there was an emphasis on structural quality more than processual and result quality matters. The findings and implications are discussed also in terms of the three areas of measuring quality: structural,result,and processual. Overall, heads might need more support and guidance from experts in order to achieve quality work in relation to processual areas of quality matters in preschool. Future research ought to examine quality of care in preschool (rather than quality of education) from the perspective of preschool heads.

Mycobacterium tuberculosis (Mtb), one of the major pathogens of mankind, kills approximately 2 million people each year. Mtb induces inflammation at the site of infection, leading to leakage of serum proteins, which in turn, are likely to come in contact with the pathogen, thus modulate the pathogenesis of tuberculosis. We studied some of these proteins such as surfactant protein D (SP-D), complement protein C1q and fibronectin, which are either produced locally or they leak-out from serum during inflammation, for their interaction with M.smegmatis and BCG. These non-pathogenic mycobacteria were used as model for Mtb. In this study, the recombinant form of truncated human surfactant protein D (rhSP-D) and three globular heads of human C1q (ghA, ghB, and ghC) were expressed in E.coli. The interaction of each of these proteins with mycobacteria and human monocytic cell line THP-1, was examined via ELISA. We demonstrated that rhSP-D, C1q, three globular heads of C1q and fibronectin bind with both mycobacteria and THP-1 cells. Moreover, using rhSP-D and globular heads of C1q, the binding of SP-D and C1q was localised to C-terminal globular regions. The direct effect for each of these proteins on mycobacterial growth, their effect on the uptake and intracellular fate of mycobacteria inside THP-1 cells were also investigated. Direct interaction of rhSP-D and C1q inhibited mycobacterial growth, whereas fibronectin interaction with the mycobacteria increased their growth. RhSP-D inhibited the uptake and growth of mycobacteria inside THP-1 cells, whereas C1q and each individual globular heads of C1q enhanced the uptake of mycobacteria by THP-1 cells. However, C1q protein inhibited BCG growth but enhanced M.smegmatis growth inside these cells and the later activity was localised to ghA. Fibronectin increased the uptake and growth of mycobacteria inside THP-1 cells. Examining the gene expression of inducible nitric oxide synthase, pro-inflammatory and anti-inflammatory cytokines produced by THP-1 cells infected with the proteins treated and untreated mycobacteria, along with cytokine neutralization experiments, suggest that the nitric oxide components and cytokines could be responsible for mycobacterial growth control inside THP-1 cells. These novel and interesting functions of SP-D, C1q, and fibronectin on mycobacteria provide an insight into the modulatory function of these proteins on Mtb infection, and, therefore, in the pathogenesis of tuberculosis.

This thesis explores a novel technique for transceiver design in future wireless systems, which is cloud radio access networks (CRANs) with single radio frequency (RF) chain antennas at each remote radio head (RRH). This thesis seeks to make three contributions. Firstly, it proposes a novel algorithm to solve the oscillatory/unstable behaviour of electronically steerable parasitic array radiators (ESPAR) when it provides multi-antenna functionality with a single RF chain. This thesis formulates an optimization problem and derives closed-form expressions when calculating the configuration of an ESPAR antenna (EA) for arbitrary signals transmission. This results in simplified processing at the transmitter. The results illustrate that the EA transmitter, when utilizing novel closed-form expressions, shows significant improvement over the performance of the EA transmitter without any pre-processing. It performs at nearly the same symbol error rate (SER) as standard multiple antenna systems. Secondly, this thesis illustrates how a practical peak power constraint can be put into an EA transceiver design. In an EA, all the antenna elements are fed centrally by a single power amplifier. This makes it more probable that during use, the power amplifier reaches maximum power during transmission. Considering limited power availability, this thesis proposes a new algorithm to achieve stable signal transmission. Thirdly, this thesis shows that an energy efficiency (EE) optimization problem can be formulated and solved in CRANs that deploy single RF chain antennas at RRHs. The closed-form expressions of the precoder and power allocation schemes to transmit desired signals are obtained to maximise EE for both single-user and multi-user systems. The results show that the CRANs with single RF chain antennas provide superior EE performance compared to the standard multiple antenna based systems.
