Measuring the use of information and communication technologies (ICTs) in the classroom

In 2003, the ICT Curriculum Integration Performance Measurement Instrument was developed from an extensive review of the contemporary international and Australian research pertaining to the definition and measurement of ICT curriculum integration in classrooms (Proctor, Watson, & Finger, 2003). The 45-item instrument that resulted was based on theories and methodologies identified by the literature review. This paper describes psychometric results from a large-scale evaluation of the instrument subsequently conducted, as recommended by Proctor, Watson and Finger (2003). The resultant 20-item, two-factor instrument, now called Learning With ICTs: Measuring ICT Use in the Curriculum is both statistically and theoretically robust. This paper should be read in association with the original paper published in Computers in the Schools (Proctor, Watson & Finger, 2003) that described in detail the theoretical framework underpinning the development of the instrument

The consistency of merger decisions at the South African Competition Commission

The South African Competition Commission’s merger decisions for fiscal year (FY) 2002 through FY2009 are analysed to empirically identify the factors historically influencing prohibition, conditional approval and unconditional approval, as well as the factors historically influencing whether merger applications are deemed non-complex, complex or very complex. The focus of the analysis is on whether or not the historical process has remained consistent through time, and whether or not that process can be obviously linked to the provisions of the 1998 Competition Act. Initial results point to behaviour that is not consistent over the time period considered; however, those inconsistencies are removed, once additional measures of market contestibility, associated with the 1998 Competition Act are included in the analysis. The final results suggest that the commission is less likely to approve mergers that they link to markets that are less contestable. In addition to protecting competition, the commission is simultaneously protecting other public interests. Therefore, our research supports the hypothesis that the commission consistently applies its legislative remit.http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1813-6982hb201

The effect of the Vaalkop replacement pegmatoid on the sulphide mineralogy at Western Platinum mine in the Mooinooi district

Western Platinum mine is situated 30 km due east of Rustenburg in the Western Bushveld Complex. Replacement pegmatoid areas occur sporadically at the mine and range in diameter from a few metres to approximately 250 m. The effect of the replacement pegmatoid was investigated in six profiles through the chromitite. The replacement pegmatoid footwall consists predominantly of amphibole with minor pyroxene, talc, clay-minerals, serpentine, olivine, and magnetite. A characteristic feature of the alteration in the UG-2 chromitite by replacement pegmatoid is the sintering of the bottom 5-10 cm. The sintered area consists of magnetite and Fe-Ti-oxides. Footwalls of “unaltered" UG-2 chromitite are anorthosite or pyroxenite. Pentlandite is the major sulphide in altered UG-2 chromitite. Chalcopyrite, chalcocite-group minerals, bomite, violarite, mackinawite, haezlewoodite, cubanite and pyrrhotite are minor constituents in altered UG-2. Trace amounts of sphalerite and millerite occur. The base metals sulphides in a reference profile of unaltered UG-2 consist primarily of pentlandite with minor chalcopyrite, pyrrhotite, and pyrite. The platinum group mineral assemblage of the altered UG-2 chromitite contains a considerable amount (36%-55%) of alloys, Bi-containing, As-containing and Te-containing platinum group minerals. The amount of arsenides increases with increasing alteration and is 2% (reference profile), 28% (average of altered UG-2 profiles 1, 3, 5, and 2) and 64% for the most intensely altered UG-2 chromitite (profile 8) respectively. The proportion of platinum group sulphides decreases from 96% to 18% with increasing alteration. Platinum group element association with sulphides decreases gradually from 87% for the reference profile to 20% for the most intensely altered UG-2 chromitite. The sulphide mineral assemblages, platinum group element assemblages, and the presence of hydrous silicates in the profiles of altered UG-2 chromitite is an indication of the presence of a late-stage hydrothermal fluid modifying a primary magmatic assemblage. This is further supported by the sintering of the oxides, the presence of Co-rich pentlandite in the sintered area, and the textural and chemical overprinting of the chromites.Dissertation (MSc)--University of Pretoria, 1995.GeologyMScUnrestricte

Exploring the adaptation challenges faced by novice foundation phase teachers in the Nelson Mandela Metropole

The challenges faced by novice teachers have been widely discussed in the last decade (Caspersen & Raaen, 2014; Burkman, 2012). It is believed that the first year of teaching is found to be exceedingly challenging to the novice teacher due to the complex demands of the profession, as well as a result of a lack of training and induction into the work environment (Burkman, 2012). Researchers highlight that some of the many challenges that novice teachers experience are shortcomings in curricular planning, classroom management and discipline, instructional techniques, access to materials, and dealing with parents (Burkman, 2012). These challenges, along with feelings of inadequacy due to lack of experience in the working world, often have a negative effect on novice teachers and their ability to cope, subsequently resulting in high stress levels and burnout (Caspersen & Raaen, 2014). This qualitative study incorporated an interpretivist paradigm and used both semistructured interviews and a focus group discussion to explore the adaptation challenges experienced by novice Foundation Phase teachers in the Nelson Mandela Metropole. Grossman‟s Teacher Knowledge Theory and Vygotsky‟s Social Constructivist Theory were used to frame and make meaning of the findings of this study. The findings of this study indicate that novice teachers experience a range of challenges upon entering the working world. The numerous factors influencing these challenges experienced by novices include: the work environment; prior training and education; personal knowledge, values and attitudes toward teaching; and professional and social support received within the workplace. These findings were used to formulate guidelines to help support novice teachers in their adaptation from university to the professional work environment.Thesis (MEd) -- Faculty of Education, 202

Teaching Teachers for the Future (TTF) Project: Development of the TTF TPACK survey instrument

This paper presents a summary of the key findings of the TTF TPACK Survey developed and administered for the Teaching the Teachers for the Future (TTF) Project implemented in 2011. The TTF Project, funded by an Australian Government ICT Innovation Fund grant, involved all 39 Australian Higher Education Institutions which provide initial teacher education. TTF data collections were undertaken at the end of Semester 1 (T1) and at the end of Semester 2 (T2) in 2011. A total of 12881 participants completed the first survey (T1) and 5809 participants completed the second survey (T2). Groups of like-named items from the T1 survey were subject to a battery of complementary data analysis techniques. The psychometric properties of the four scales: Confidence - teacher items; Usefulness - teacher items; Confidence - student items; Usefulness- student items, were confirmed both at T1 and T2. Among the key findings summarised, at the national level, the scale: Confidence to use ICT as a teacher showed measurable growth across the whole scale from T1 to T2, and the scale: Confidence to facilitate student use of ICT also showed measurable growth across the whole scale from T1 to T2. Additional key TTF TPACK Survey findings are summarised

The Mismatch between Australian Population and General Practice Medical Workforce

Aims: To review and analyse Australian general practitioner's workforce data for the 2000 to 2010 period by comparing this to Australian population trends and to make informed recommendations about GP workforce planning. Study Design: Descriptive analysis of the available Australian government data on GP workforce and the Australian population between 2000 and 2010. Place and Duration of Study: Griffith University, Australia, between April and November 2011. Methodology: Australian GP workforce data for the 2000 to 2010 period was obtained from the Australian Department of Health and Ageing (DoHA) website and population data was obtained from the Australian Bureau of Statistics website. A descriptive analysis of workforce trends using variables of interests such as overseas trained GPs, gender, age, professional services during the 11 year period was compared to population trends data. A new GP Workforce Index ratio (GPWIR = No. of GPs <35yrs 砎o. of GPs 35yrs to 64yrs of age) was derived from the data and calculated for each year of the study period. Results: The ratio of female to male GPs has increased by 35% and the percentage of overseas graduates has increased by nearly 35% in the 11 year period, an indication that the 0.12% number of GPs as a percentage of Australian population between 2000 and 2010 was only sustained by increasing the intake of foreign trained graduates. Vocationally registered GPs have increased by 20% in same period. The GP workforce index ratio (GPWIR) decreased from 0.223 in 2000 to 0.118 in 2007; this was followed by a slight increase from 0.120 in 2008 to 0.128 in 2010. Conclusion: The impact that an increase in the number of female GPs graduating from medical schools may have on the overall number of GP services available to the Australian population requires further study, since it was noted in the literature that female GPs are more likely to work part-time than male GPs. The GPWIR may be a useful indicator for evaluating the proportion of the <35yrs old GPs as a proportion of overall GP workforce. Lower GPWIR may be associated with GP workforce shortage. GPWIR increased in the last 3 years of the study corresponding with an improvement in GP supply. In this study, the GPWIR proved to be more effective in predicting overall National GP workforce shortage trend than the DoHA GP per Population ratio of 0.71:1000 (Primarily used for regional and rural workforce shortage prediction). The Department of Health and Ageing may need to keep supporting rural and remote migration of GPs and also maintain an increase in the number of students entering medical schools.Griffith Health, School of Nursing and MidwiferyFull Tex

Personality traits, brie' recurrent depression and attempted suicide

This study investigated the relationship between attempted suicide, personality factors and brief recurrent depression. Over a period of 1 year, the demographic and psychiatric factors of 307 patients who had attempted suicide and subsequently been hospitalised at H. F. Verwoerd Hospital and referred to its Department of Psychiatry were recorded. Their personality traits were evaluated clinically. After 5 years, 205 respondents were traced to complete a follow-up questionnaire and, where possible, a personality assessment was completed on clinical grounds. They were also evaluated for brief recurrent depression. Among the men, antisocial, dependent and histrionic personality traits, in that order, were most commonly noted and among the women, histrionic, dependent and antisocial traits. A clear relationship between suicidal behaviour and the syndrome of brief recurrent depression was established. The latter was also found to be related to histrionic personality traits in women. This underscores the relationship between suicide attempts and histrionic personality traits

Water stress affects the germination, emergence, and growth of different sorghum cultivars

Two experiments were conducted to study the effects of water deficit stress on the germination, emergence and seedling growth of sorghum [Sorghum bicolor (L.) Moench] using Completely Randomised Block Design in four replications. Five sorghum cultivars (Jigurti, Gambella 1107, Meko, 76 T1 #23 and P9403) were evaluated under three water deficit stress treatments (0, -0.20 and -0.85 MPa) using PEG as an osmoticum (Experiment I) and under four varying growing media water contents (100, 60, 40 and 20% of field capacity) using sand (Experiment II). In both experiments, water deficit stress significantly reduced the rate and percentage of germination and emergence and early seedlings growth. Coleoptile, mesocotyl, radicle, and seedling shoot and root lengths, as well as root area were adversely affected by water deficit stress. Cultivars differed in the rate and percentage of germination, and emergence and seedling growth. Gambella 1107, Meko and P9403 had significantly (
