  • an empirical Study of stock split announcements of select bse sectors using event Study Methodology
    SDMIMD Journal of Management, 2015
    Co-Authors: Asha Nadig
    Abstract:

    This Study examines the stock market reaction to stock splits between 2002 and 2013 of 6 sectors of BSE-Auto, Bankex, Consumer Durables, FMCG, Health Care and IT sectors to find out if the Indian stock market is semi-strong efficient or not. The Methodology used is event Study under the market model. Samples of 14 stock splits are considered spread across 6 sectors. The results indicate that there are significant positive abnormal returns prior to split announcements. On the day of split announcement, 1 sector reacts positively (Health Care-3.3%) and the 5 react negatively (Auto -1%, Bankex -0.9%, CD -0.3%, FMCG -1%, and IT-1%). The results indicate that the null hypothesis, H 0 1, that there is no significant AAR around the stock split announcement dates is accepted.

  • exploring the role of mental health first aid officers in workplaces a qualitative Study using case Study Methodology
    International Journal of Workplace Health Management, 2018
    Co-Authors: Nataly Bovopoulos, Anthony D Lamontagne, Angela Martin, Anthony F Jorm
    Abstract:

    An emerging trend in Australian workplaces is to appoint staff trained in mental health first aid as mental health first aid officers (MHFAOs), similar to physical first aid officers (PFAOs) focused on physical health emergencies. The purpose of this paper is to better understand the nature of MHFAO roles in workplaces and develop recommendations for other workplaces.,A case Study Methodology was used, with semi-structured qualitative interviews conducted with multiple individuals within five diverse organisations.,The results indicated that organisations tended to differ in their approach to implementation, based on their level of experience. There was a strong agreement across organisations on the benefits and challenges they have experienced with the role.,Organisational representatives highlighted some important differences between PFAO and MHFAO roles. Respondents across all organisations agreed that MHFA training should ideally be offered to all staff if feasible, not only MHFAOs. The greatest challenge experienced by respondents was inadequate support to, and internal resourcing for, MHFAO roles. Respondents suggested that workplaces provide more support and training to MHFAOs.,This is the first Study to explore and describe the experiences of workplaces with MHFAOs. Recommendations are made to assist interested organisations in these efforts.

  • transitions Study of predictors of illness progression in young people with mental ill health Study Methodology
    Early Intervention in Psychiatry, 2015
    Co-Authors: Rosemary Purcell, Anthony F Jorm, Ian B Hickie, Alison R Yung, Christos Pantelis, G P Amminger, Nick Glozier, Eoin Killackey, Lisa J Phillips
    Abstract:

    Aim An estimated 75% of mental disorders begin before the age of 24 and approximately 25% of 13–24-year-olds are affected by mental disorders at any one time. To better understand and ideally prevent the onset of post-pubertal mental disorders, a clinical staging model has been proposed that provides a longitudinal perspective of illness development. This heuristic model takes account of the differential effects of both genetic and environmental risk factors, as well as markers relevant to the stage of illness, course or prognosis. The aim of the Transitions Study is to test empirically the assumptions that underpin the clinical staging model. Additionally, it will permit investigation of a range of psychological, social and genetic markers in terms of their capacity to define current clinical stage or predict transition from less severe or enduring to more severe and persistent stages of mental disorder. Method This paper describes the Study Methodology, which involves a longitudinal cohort design implemented within four headspace youth mental health services in Australia. Participants are young people aged 12–25 years who have sought help at headspace and consented to complete a comprehensive assessment of clinical state and psychosocial risk factors. A total of 802 young people (66% female) completed baseline assessments. Annual follow-up assessments have commenced. Conclusions The results of this Study may have implications for the way mental disorders are diagnosed and treated, and progress our understanding of the pathophysiologies of complex mental disorders by identifying genetic or psychosocial markers of illness stage or progression.

  • research report a reexamination of it investment and the market value of the firm an event Study Methodology
    Information Systems Research, 2001
    Co-Authors: Kun Shin Im, Varun Grover
    Abstract:

    Evaluating the effectiveness of Information Technology (IT) investments has always been an elusive but important goal of IS researchers. This Study builds on a prior Study that examined changes in the market value of the firm as reflected by the stock price in response to IT investment announcements. Data on stock prices were analyzed for 238 publicly traded companies. In addition to the stock price analysis, reaction of trading volume to the announcements was also examined to identify whether IT investment announcements affect investors' beliefs about IT value. Potentially confounding factors such as industry, size, and time lag effects were also analyzed. Size and time lag effects were found for all IT investment announcements. Reactions of price and volume were negatively related to firm size and became more positive over time. The positive excess return for smaller firms shows that smaller firms can leverage the lower price/performance ratio of new IT and reap greater rewards from IT investments than larger firms. Also, the result of time lag effect demonstrates that the stock market has recently begun to identify both tangible and intangible benefits of IT investments. For recent IT investment announcements, industry classification and firm size also affected the reactions of stock price to the announcements. This Study provides optimism on the stock market reaction to IT investment announcements as well as further insight into the Study of IT impacts on organizational performance.

  • revisiting typhoid fever surveillance in low and middle income countries lessons from systematic literature review of population based longitudinal studies
    BMC Infectious Diseases, 2015
    Co-Authors: Vittal Mogasale, Enusa Ramani, Jungseok Lee, Ju Yeon Park, Kang Sung Lee, Thomas F Wierzba
    Abstract:

    The control of typhoid fever being an important public health concern in low and middle income countries, improving typhoid surveillance will help in planning and implementing typhoid control activities such as deployment of new generation Vi conjugate typhoid vaccines. We conducted a systematic literature review of longitudinal population-based blood culture-confirmed typhoid fever studies from low and middle income countries published from 1st January 1990 to 31st December 2013. We quantitatively summarized typhoid fever incidence rates and qualitatively reviewed Study Methodology that could have influenced rate estimates. We used meta-analysis approach based on random effects model in summarizing the hospitalization rates. Twenty-two papers presented longitudinal population-based and blood culture-confirmed typhoid fever incidence estimates from 20 distinct sites in low and middle income countries. The reported incidence and hospitalizations rates were heterogeneous as well as the Study Methodology across the sites. We elucidated how the incidence rates were underestimated in published studies. We summarized six categories of under-estimation biases observed in these studies and presented potential solutions. Published longitudinal typhoid fever studies in low and middle income countries are geographically clustered and the Methodology employed has a potential for underestimation. Future studies should account for these limitations.
