A study of follower's personality,implicit leadership perceptions,and leadership ratings

This research was designed to test the theoretical relationship between personality, implicit leadership, and leadership style suggested in past studies. Specifically, it was designed to link traits from the five‐factor model of personality (the Big Five), by utilizing the International Personality Item Pool (IPIP), to a follower's perception of the leadership style of George W. Bush, based on Bass and Avolio's (1997) MLQ5X. A voluntary sample was taken consisting of undergraduate and graduate students from three universities in southern Texas in 2006, with a sample size of N = 303. Respondents who scored high in neuroticism rated the leader as less transformational than those who did not. Also, the ancillary variable good leadership had a positive effect on the respondent's ratings of the leader as a transformational leader, and as a less passive leader, than subjects who did not rate the leader as being a good leader. There was a significant relationship found between respondents' political party affiliation and their transformational and passive leadership ratings. Implications of these findings are discussed in terms of the Obama versus McCain presidential race.     

Virtual communication,transformational leadership,and implicit leadership

This research was designed to test the theoretical relationship among personality, implicit leadership, and transformational leadership in a setting devoid of face‐to‐face communication, which we entitled virtual communication. Specifically, the study was designed to link, by using the International Personality Item Pool (IPIP), traits from the 5‐factor model of personality (the Big 5) to followers' perception of the leadership style of a virtual leader on the basis of Bass and Avolio's MLQ‐5X (1994). A voluntary sample consisted of undergraduate and graduate students from two universities in the south Texas area (N = 306). Respondents to the virtual communication rated Leader 1's communication, which used previously identified transformational language (Salter, Carmody‐Bubb, Duncan, & Green, 2007), as significantly more transformational than Leader 2's communication, using words not associated with transformational leaders. Participants who scored high in the Big 5 personality traits of agreeableness, openness to experience, conscientiousness, and extraversion rated the leader as more transformational while those high in neuroticism rated the leader as less transformational.     

High-frequency financial data modeling using Hawkes processes

Intraday Value-at-Risk (VaR) is one of the risk measures used by market participants involved in high-frequency trading. High-frequency log-returns feature important kurtosis (fat tails) and volatility clustering (extreme log-returns appear in clusters) that VaR models should take into account. We propose a marked point process model for the excesses of the time series over a high threshold that combines Hawkes processes for the exceedances with a generalized Pareto distribution model for the marks (exceedance sizes). The conditional approach features intraday clustering of extremes and is used to calculate instantaneous conditional VaR. The models are backtested on real data and compared to a competitor approach that proposes a nonparametric extension of the classical peaks-over-threshold method. Maximum likelihood estimation is computationally intensive; we use a differential evolution genetic algorithm to find adequate starting values for the optimization process.     

The Variation of Homeowner Tax Preferences by Income, Age and Leverage

It is well known that owner-occupied housing has long received favorable tax treatment in the U.S. federal income tax system relative to a system in which all income, regardless of its source, is subject to taxation. As a result, many economists have argued that the United States overinvests in owner-occupied housing relative to the investment that would result from a neutral income tax system. In addition, the distribution of the subsidy is often viewed as inequitable because high-income households receive the largest subsidy per dollar of housing. This article uses the 2005 American Housing Survey, conducted by the U.S. Department of Commerce, to perform a microlevel analysis of the current magnitude and distribution of homeowner tax preferences. We then assess how the magnitude and distribution of tax preferences would be altered by replacement of the mortgage interest deduction with a 15% credit.     

HMTS: Improving the quality of public service announcements through standardized pretesting

Traditionally, health message producers have relied on their own creative communication skills to reach and affect the public with health information. The Health Message Testing Service provides additional input regarding target audience response to health messages. Paired with creative PSA production, these data can more reliaby ensure audience receptivity and response. By testing messages in a pre-finished form, the producer can identify and correct potential weaknesses while corrections are still timeand-budget affordable.

NEW ESTIMATES OF GROSS NATIONAL PRODUCT FOR THE UNITED KINGDOM 1830–1914

This paper presents a new annual series for United Kingdom gross national product, at current and constant prices, calculated from the expenditure side. These results differ significantly from previous estimates in that they go back to the beginning of the railway age on an annual basis and also in that the constant price estimates involve a detailed deflation of the main components of expenditure on consumption and capital formation. The implications of the new results are summarised, with particular reference to rates of growth and relative price changes, and an appendix describes the sources of the estimates.     

Predicting consumers' reactions to product failure: Do responsibility judgments follow from consumers' causal explanations?

Recent research in psychology suggests that people's causal attributions for an occurrence may not reflect the entirety of their beliefs about how the event transpired but rather which subset of this information has explanatory relevance given the context of the causal question. The present research examines the implications of this proposition for causal judgments about product failure and manufacturer responsibility. An experiment is presented which shows that consumers' attributions for product failure — to manufacturer-related vs. consumer-related factors — may vary with the causal background or reference case against which the occurrence is considered. These findings are discussed in light of previous research in marketing which suggests responsibility judgments should be related to the locus of consumers' attributions.     

An Analysis of Potential Legal Liability Incurred Through Audit Expert Systems

The introduction of expert systems technology into the audit environment has opened a new avenue of auditor legal liability. This paper examines the potential impact expert systems will have on auditor liability. The presentation of this new avenue of auditors' legal liability explores both the potential for litigation under failure of auditor/expert system collaboration to yield prudent decisions and the failure to use an available expert system. The risks evolving from failure to use an available expert system include the possibility that the system could be used against the auditor in the courtroom. While case law will ultimately determine the bounds of this liability, this paper acquaints the reader with the important legal issues involved and the varied outcomes that could emerge. It should also be noted that while the specific example presented in this paper relates to the audit profession, the legal concepts are of equivalent concern to other professions enduring broad implementation of expert systems.     

Examining the overseas staffing options utilized by Australian headquartered multinational corporations

MNCs need to use a range of options to manage their international operations. The aim of this study was to enhance understanding of how MNCs staff international management positions using a sample of top Australian MNCs across a range of industries. The rationales executives gave for their MNCs' staffing of international management supported selecting managers with higher competency levels for complex overseas assignments. Staffing options were chosen to reduce risks from cultural friction, divergent goals, and asymmetry in knowledge between the parent company and the host operation, chiefly through staffing by parent country nationals (i.e. long-term expatriates, Australians or Westerners already living in the host country or abroad, domestic international managers). Host country managers were used to reduce risks that arose from not being responsive to the host environment and to avoid costs, and when they were least risky to the firm. By contrast, the staffing options also served practical purposes, including deploying expatriate managers to provide skills (competencies) and, less frequently, to develop managers for future management positions in the organization.     

Researching expatriate types: the quest for rigorous methodological approaches

International talent flow is critical to meeting the needs for skilled human capital in global and multinational organisations and in developed and developing countries. Recent decades have witnessed a boom in research into long‐term skilled international mobility, especially the traditional category of international assignees, but also skilled immigrants and a relatively new expatriate type: self‐initiated expatriates. The upsurge in empirical interest has highlighted a number of issues relating to the way the research has been conducted. This article examines methodological issues associated with research into the three expatriate types and seeks to advise researchers on how future research can be conducted to improve the robustness of results. In this way, practitioners and policy makers may be able to make more use of the empirical evidence.
