Temporal Aggregation And Risk-Return Relation, Xing Jin, Leping Wang, Jun Yu

Research Collection School Of Economics

The function form of a linear intertemporal relation between risk and return is suggested by Merton's [1973. Econometrica 41, 867–887] analytical work for instantaneous returns, whereas empirical studies have examined the nature of this relation using temporally aggregated data, i.e., daily, monthly, quarterly, or even yearly returns. Our paper carefully examines the temporal aggregation effect on the validity of the linear specification of the risk–return relation at discrete horizons, and on its implications on the reliability of the resulting inference about the risk–return relation based on different observation intervals. Surprisingly, we show that, based on the standard Heston's [1993. Review …

Modeling Transaction Data Of Trade Direction And Estimation Of Probability Of Informed Trading, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitch Warachka

Research Collection School Of Economics

This paper implements the Asymmetric AutoregressiveConditional Duration (AACD) model of Bauwens and Giot (2003) to analyzeirregularly spaced transaction data of trade direction, namely buy versus sellorders. We examine the influence of lagged transaction duration, lagged volumeand lagged trade direction on transaction duration and direction. Our resultsare applied to estimate the probability of informed trading (PIN) based on theEasley, Hvidkjaer and O’Hara (2002) framework. Unlike the Easley-Hvidkjaer-O’Hara model, which uses the daily aggregate number of buy and sellorders, the AACD model makes full use of transaction data and allows forinteractions between buy and sell orders.

Double lumen endotracheal tube was placed for lung isolation and episodes of hypertension during proximal and distal cross clamp were controlled with sodium nitropruside infusion (SNP). Extra pleural catheter was put in at the end of surgery before chest wall closure for postoperative pain control. Both upper and lower …

Anaesthesia For Interventional Neuroradiology, Aliya Ahmed

Department of Anaesthesia

There have been rapid and significant advances in diagnostic and interventional radiology, including interventional neuroradiology, in recent years. Many intracranial vascular pathologies are being successfully managed by endovascular interventional neuroradiology techniques. These techniques include procedures like embolization of vascular tumours and arterio-venous malformations, coiling of cerebral aneurysms. etc. The support of anaesthesia team is requested for these therapeutic endovascular neuroradiological procedures. The main aims of the anaesthesiologist during any interventional neuroradiology procedure are provision of a physiologically stable and immobile patient, alteration of arterial blood pressure as necessary, and appropriate and timely management of complications.

Fatigue's Influence On Workload, Situation Awareness, And Performance In A Military Simulation Of Combat, Carlotta M. Boone

Psychology Theses & Dissertations

Military operations routinely require military personnel to consistently perform their duties over several hours or days. Tasks that require prolonged work can lead to mental fatigue and decreased performance. The transactional model proposes that individuals cope with changes in the environment and maintain performance. This ability to cope is determined by factors of the environment and the individual's personality. One environmental factor that can influence coping is extended task performance. This study examined the effect of extended task performance and its interaction with task difficulty. Participants interacted with the military simulation game Command and Conquer: Generals™ for three hours. They …

The nonprobability purposeful sample of undergraduate students consisted of 122 preservice teachers who were attending a …

Investigation Of A Possible Lead-Lag Relationship Between The Innuitian And Laurentide Ice Sheets, Arctic Canada, Paula Zimmerman

OES Theses and Dissertations

Peaks of iron-rich grains in Arctic Ocean sediment cores matched to the Laurentide and Innuitian Ice Sheets appear to show a lead-lag relationship during the Late Pleistocene when grain abundances are plotted against time and depth below sea floor. Cores from across the Arctic have been analyzed to determine if this is the case. Of the six IRD events identified, the Innuitian leads 68% of the time with 26% of events in all cores occurring simultaneously. The Innuitian seems to lead 33.3% of the time when peaks from the Innuitian and Laurentide occur within close proximity (less than 1 cm), …

'Negotiated' Transparency? Corporate Citizenship Engagement And Environmental Disclosure, Scott Marshall, Darrell Brown, Marlene Plumlee

Business Faculty Publications and Presentations

Corporate stakeholder relations are historically typified by power imbalances and mistrust, but in recent times, they are increasingly characterized by 'dialogue' based on mutual understanding and creative action. In this paper we consider corporate engagements with two external stakeholder groups, citizenship-focused non-governmental organizations (NGO) and institutional investors, and examine the potential association between these engagements and corporate disclosure of environmental information. Based on a sample of 183 firms over a three-year time period, we analyze the relationships between NGO engagement, investor activism and the quality of corporate voluntary environmental disclosure. Our findings suggest that engagement with skills-focused NGOs and the …

21st Century Women Leaders: Uncharted Journey, S. Irene Matz

Iowa Journal of Communication

This study looked at women in three professional arenas-academe, business and government-and measured the degree of emphasis placed on six leadership styles. Results of the test indicated the six styles existed in all three arenas; however, an analysis demonstrated consensus was the most favored overall while academicians emphasized the consensual style to a greater extent than business and government professionals. Implications for women's leadership are discussed.

Feminist Film And The Dilemma Of Killing Us Softly, Joanne Morreale

Iowa Journal of Communication

This essay traces the trajectory of Killing Us Softly, the classic feminist film critique of images of women in advertising. All four versions of the film from 1979 to 2001 provide insight into the social/historical context of the women's movement and its influence on advertising while simultaneously illustrating the influence of advertising on feminist discourse. As the original 1979 film is transformed in 1987, 2000, and 2001, this article analyzes its formal and strategic shifts in order to assess how feminist pedagogical films can best serve as tools for achieving social and political change.

Abuse And Dissociation Disorder, Myrtle Godfrey

Graduate Research Papers

Child sexual abuse is widely regarded as a cause of mental problems in adult life. The damage inflicted by child sexual abuse.has an affect on the child's capacity to develop trust, intimacy and sexuality. Sexually abused children not only encounter assaults on their developing sense of sexual identity, but a blow to their interpretation of the world as a safe environment, and their developing sense of others as trustworthy. In addition, childhood sexual abuse is correlated with higher levels of dissociation. (Fleming, J. & Mullen, P. E., 1998). Of the victims that were abused by someone with whom he or …
