Student Performance in First Year, Mathematics, and Physics Courses: Implications for Success in the Study of Electrical and Computer Engineering

Mathematics and physics courses are recognized as a crucial foundation for the study of engineering, and often are prerequisite courses for the basic engineering curriculum. But how does performance in these prerequisite courses affect student performance in engineering courses? This study evaluated the relationship between grades in prerequisite math and physics courses and grades in subsequent electrical engineering courses. Where significant relationships were found, additional analysis was conducted to determine minimum grade goals for the prerequisite courses. Relationships were found between five course pairs: calculus II and differential equations; calculus II and physics I (mechanics); physics II (electricity and optics) and circuits analysis II; physics II (electricity and optics) and signals and systems; and circuits analysis II and signals and systems. The results indicate that a grade of C+ or higher in calculus II, and a grade of B- or higher in physics II and circuits analysis II will lead to higher grades in subsequent mathematics, circuits, and signals and systems courses. This information will be used to aid faculty in making decisions about imposing minimum grade requirements

Financial reporting on corporate real estate: a study of the annual reports of non-investment companies listed on the New Zealand Stock Exchange (NZSE)

Corporate Real Estate (CRE) is a significant asset, which has been shown to add value to businesses if it is efficiently and effectively managed. Globalisation of capital markets, advancements in technology and the current economic condition have again increased the awareness of the importance of CRE’s contribution. In order to be successful businesses need CRE to create and maintain their competitive edge in the marketplace. Advancement in terms of Corporate Real Estate Asset Management (CREAM) and the positive attitude shift of executives towards corporate real estate (CRE) have been made possible through research into the contribution CRE makes to a business’s bottom line. The objective of this study is to describe the financial reporting practices of companies (excluding investment companies) listed on the New Zealand Stock Exchange (NZSE) in order to reveal the current attitudes of management towards CRE. The results showed that information chaos exists behind the façade of the Balance Sheet, revealing that management have a surface level attitude and lack a real focus towards CRE assets. In New Zealand and overseas there is minimal literature that this study could build upon. The methodology involved an exploratory study of the 2008 annual reports; the results formed a snap shot of the current reporting practices of CRE and revealed the current attitudes of management in entities towards CRE

Intrapartum epidural analgesia and breastfeeding: a prospective cohort study

BACKGROUND Anecdotal reports suggest that the addition of fentanyl (an opioid) to epidural analgesia for women during childbirth results in difficulty establishing breastfeeding. The aim of this paper is to determine any association between epidural analgesia and 1) breastfeeding in the first week postpartum and 2) breastfeeding cessation during the first 24 weeks postpartum. METHODS A prospective cohort study of 1280 women aged > or = 16 years, who gave birth to a single live infant in the Australian Capital Territory in 1997 was conducted. Women completed questionnaires at weeks 1, 8, 16 and 24 postpartum. Breastfeeding information was collected in each of the four surveys and women were categorised as either fully breastfeeding, partially breastfeeding or not breastfeeding at all. Women who had stopped breastfeeding since the previous survey were asked when they stopped. RESULTS In the first week postpartum, 93% of women were either fully or partially breastfeeding their baby and 60% were continuing to breastfeed at 24 weeks. Intrapartum analgesia and type of birth were associated with partial breastfeeding and breastfeeding difficulties in the first postpartum week (p < 0.0001). Analgesia, maternal age and education were associated with breastfeeding cessation in the first 24 weeks (p < 0.0001), with women who had epidurals being more likely to stop breastfeeding than women who used non-pharmacological methods of pain relief (adjusted hazard ratio 2.02, 95% CI 1.53, 2.67). CONCLUSION Women in this cohort who had epidurals were less likely to fully breastfeed their infant in the few days after birth and more likely to stop breastfeeding in the first 24 weeks. Although this relationship may not be causal, it is important that women at higher risk of breastfeeding cessation are provided with adequate breastfeeding assistance and support.Christine Roberts is supported by a National Health and Medical Research Council (NHMRC) of Australia Public Health Practitioner Fellowship and Siranda Torvaldsen is supported by a NHMRC Australian Research Training Fellowship.

Social anxiety following traumatic brain injury:an exploration of associated factors

Social anxiety (SA) following traumatic brain injury (TBI) has the potential to affect an individual’s general psychological well-being and social functioning, however little research has explored factors associated with its development. The present study used hierarchical multiple regression to investigate the demographic, clinical and psychological factors associated with SA following TBI. A sample of 85 people who experienced TBI were recruited through social media websites and brain injury services across the North-West of England. The overall combined biopsychosocial model was significant, explaining 52–54.3% of the variance in SA (across five imputations of missing data). The addition of psychological variables (self-esteem, locus of control, self-efficacy) made a significant contribution to the overall model, accounting for an additional 12.2–13% of variance in SA above that explained by demographic and clinical variables. Perceived stigma was the only significant independent predictor of SA (B = .274, p = .005). The findings suggest that psychological variables are important in the development of SA following TBI and must be considered alongside clinical factors. Furthermore, the significant role of stigma highlights the need for intervention at both an individualised and societal level

Factors associated with self-esteem following acquired brain injury in adults:a systematic review

Self-esteem is potentially a key factor in psychological and psychosocial well-being following acquired brain injury (ABI). The current review aimed to identify, synthesise and appraise all existing quantitative empirical studies on predictors or correlates of self-esteem following ABI in adulthood. In total, 27 papers met the inclusion criteria. A range of clinical factors were related to self-esteem after ABI, including the degree of physical and functional impairment. It is unclear if cognitive impairment is related to high or low self-esteem. Additionally, psychological variables such as coping styles, adjustment and perception of problems or rehabilitation are related to self-esteem following ABI. Depression is strongly associated with low self-esteem, alongside anxiety, psychological distress and quality of life. Limitations of the available research and recommendations for clinical practice and further research are discussed. In particular, there is a need to engage with contemporary theoretical understandings of self-esteem, integrated with and supported by developments in how self-esteem is conceptualised and measured over time in an ABI population. The findings of the review suggest that self-esteem is an important factor to consider following ABI, particularly in the context of developing individualised, formulation-driven rehabilitation interventions that take into account biological, social and psychological factors

Free to bound to free? Interactions between pragmatics and syntax in the development of Australian pronominal systems

Data from dual pronoun systems in Australian languages is used to show the pragmatic basis for a cycle of pronoun creation - reduced pronouns from free forms and free from reduced - and the motivation to maintain both types in a linguistic system. Free pronouns become positionally restricted reduced forms by association of clause-initial position with discourse prominence (Swartz 1988, Choi 1999). The same pragmatic motivations result in the creation of new free pronouns, and the divergence of free and reduced pronouns with respect to ergative case marking. Examples of languages at different stages of the cycle include Garrwa (one set of free pronouns, with a strong preference for second position); Djambarrpuyngu and Gupapuyngu (two sets of pronouns transparently related in form and in complementary distribution); Ritharrngu, Djinang, and Djinba (two sets of pronouns transparently related in form but in which the reduced pronouns are becoming obligatory); Warlpiri (two sets of pronouns, which diverge in form, and the reduced set is obligatory); and Warumungu (one set of reduced pronouns, indicating how new free pronouns might emerge based on information-packaging principles). The creation of free pronouns from reduced pronouns argues against strict unidirectionality of change
