Antecedents of Shareholder Activism in Target Firms: Evidence from a Multi-Country Study

CORPORATE GOVERNANCE, Issue 4 2010
William Q. Judge
ABSTRACT Manuscript Type: Empirical Research Question/Issue: This study seeks to better understand the antecedents of shareholder activism targeted at firms located in three common law countries (i.e., USA, UK, and Australia) and three civil law countries (Japan, Germany, and South Korea) during the 2003,07 time period. Research Findings/Insights: Our findings suggest that the antecedents of shareholder activism vary by the motivation of the activist. We demonstrate that activists target firms with two motives (a) to improve the financial performance, and (b) to improve the social performance of the firm. With respect to the target firm level antecedents, we find that firm size is unrelated to financial activism, but positively related to social activism; ownership concentration is negatively related to both financial and social activism; and prior profitability is negatively related to financial activism, but positively related to social activism. Further, these relationships in the case of financial activism are generally stronger in common law legal systems, whereas those in the case of social activism are generally stronger in environments with a greater level of income inequality. Theoretical/Academic Implications: Our findings suggest that future research should differentiate between the motivations of the activism event. Further, we find that while agency logic works well for financial activism, institutional theory provides stronger explanations for social activism. Overall, we demonstrate the complementary nature of these two theories in explaining shareholder activism. Practitioner/Policy Implications: We found that the "exposure" to shareholder activism varies by the motivation of the activist, and the nature of the firm and its national context. An understanding of these issues would help firms develop proper response strategies to activism events. [source]

Looking beyond food aid to livelihoods, protection and partnerships: strategies for WFP in the Darfur states

DISASTERS, Issue 2007
Helen Young
The humanitarian crisis in Darfur remains extremely serious. The optimism that followed the signing of the Abuja Peace Accord was followed by a rapid deterioration in security on the ground in part associated with increasing factionalism in various rebel movements. This paper briefly reviews the evolution of the crisis, its impact on lives and livelihoods and the response by the World Food Programme (WFP) to June 2006. The major challenges and issues facing the food aid programme in the previous 18 months included: dealing with insecurity while maintaining or even extending programme outreach; the need to link protection with assistance more explicitly; and determining the wider impact of food aid programming on the processes and institutions linked with the conflict. The paper discusses the main strategic issues facing WFP in the future such as: integrating security and protection with needs assessments and operational decisions, broadening response strategies beyond food aid and bringing livelihoods to the fore, the need to review cost-efficiency, promoting partnerships and strengthening national and regional capacities.

Cholinergic and noncholinergic septal neurons modulate strategy selection in spatial learning

EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 11 2001
Jonathan F. X. Cahill
Abstract Rats solving a simple spatial discrimination task in a plus maze initially employ a place-learning strategy, then switch to a motor response strategy. The hippocampus is required for the use of a place-learning strategy in this task. Rats with 192 IgG-saporin lesions of the medial septum/vertical limb of the diagonal band (MS/VDB), that selectively removed cholinergic neurons projecting to the hippocampus, were significantly facilitated in acquisition of the spatial discrimination, and switched from place to response strategies just as control rats did. Rats with ibotenic acid lesions of the MS/VDB, that produced cell loss in the MS/VDB but little damage to cholinergic neurons, were significantly impaired in acquiring the spatial discrimination and did not reliably employ either a place or response strategy at any point in training. This suggests that the MS/VDB modulates hippocampal involvement in place learning, but that cholinergic MS/VDB neurons are neither necessary nor sufficient for using a place strategy to solve a spatial discrimination.

Personality, expectations, and response strategies in multiple-choice question examinations, in university students: a test of Gray's hypotheses

EUROPEAN JOURNAL OF PERSONALITY, Issue 1 2004
César Ávila
The relation between personality and type of error made in multiple-choice examinations when correction for guessing is applied was investigated across two studies. Our general hypothesis was that disinhibited subjects (those scoring high on the Sensitivity to Reward (SR) scale and/or low on the Sensitivity to Punishment (SP) scale) would make more incorrect responses and fewer omission errors (blanks) than inhibited subjects (those with high SP and/or low SR scores). The meta-analyses of 19 examinations in study 1 confirmed our hypotheses for SP, SR, and extraversion. Regression analyses on effect sizes revealed that SP differences were obtained in examinations with low marks, whereas SR differences were obtained in examinations with more responses and fewer questions. Study 2 showed that a low-mark expectation increased omissions in high-SP subjects, whereas a high-mark expectation increased incorrect responses in high-SR subjects. These results suggest two different mechanisms mediating inhibition/disinhibition: one associated with aversive motivation, and the other with appetitive motivation.

Employer strategies in the face of a national minimum wage: an analysis of the hotel sector

INDUSTRIAL RELATIONS JOURNAL, Issue 3 2000
Donna Brown
The introduction of the National Minimum Wage provides an opportunity to examine whether hotel managers act strategically. Most of our sample are affected by this wage floor, and their managers have selected clear response strategies. The majority, 55 per cent, planned to adopt cost minimisation techniques and one third the quality enhancement route. [source]

Building the Other, Constructing Ourselves: Spatial Dimensions of International Humanitarian Response

INTERNATIONAL POLITICAL SOCIOLOGY, Issue 3 2008
Lisa Smirl
Humanitarian reconstruction after a large-scale natural disaster has become a key site of international politics; a site where global assumptions, relationships, and responsibilities are negotiated, solidified and questioned. While post-crisis response strategies and institutional practices have strong spatial and material characteristics, these are rarely considered as significant,either to the reconstruction effort, or to international politics more generally. This article identifies and examines the "auxiliary space" created by the everyday practices of international aid workers and asks whether its effects may lead to unanticipated and potentially transformative outcomes not only for the reconstruction effort, but also for global North-South relations at large. The article concludes that post-crisis reconstruction sites may offer both cautionary and emancipatory potential for the evolution of international relations. [source]

The Politics of Hostage Rescue: Is Violence a Route to Political Success?

JOURNAL OF CONTINGENCIES AND CRISIS MANAGEMENT, Issue 2 2001
Joseph Scanlon
Over the years, law enforcement agencies have acquired extensive experience with hostage incidents, and most Western countries have officers trained in all aspects of hostage resolution. There are also articles and manuals outlining how to deal with the media coverage of hostage takings (Scanlon, 1989). However, because hostage rescue efforts can provide dramatic visuals that attract enormous audiences, the media have steadily intensified their coverage of such incidents. Today, a group of previously obscure persons can suddenly dominate the media agenda by successfully resisting an armed assault or by seizing hostages and calling themselves terrorists. After defining a hostage incident and looking at the strategy for dealing with such incidents, this article examines the implications of two fatal incidents: the stand-off involving religious fanatics at Waco, Texas; and the Air France hijacking that started in Algiers and ended in Marseille, France. Both became number one on the Western media agenda, and both became political crises involving the head of state; one threatening a president's credibility, the other enhancing a president's status. Together they suggest that the escalating media coverage of such incidents raises questions not only about the effectiveness of current response strategies, but also about political leadership. This article discusses a number of strategies that have been tried or suggested. It also debates whether involvement has a positive or negative effect on political leaders. It concludes that, from the evidence available, a successful hostage rescue can yield political rewards. [source]

Coping with variability and change: Floods and droughts

NATURAL RESOURCES FORUM, Issue 4 2002
Zbigniew W. Kundzewicz
Floods and droughts are natural phenomena for which the risks of occurrence are likely to continue to grow. Increasing levels of exposure and insufficient adaptive capacity are among the factors responsible for the rising vulnerability. The former is conditioned by anthropopressure (e.g., economic development of flood,prone areas) and adverse effects of climate change; scenarios for future climates indicate the possibility of amplified water,related extremes. This article presents the current situation of coping with extreme hydrological events within the pressure,state,response framework. Among promising response strategies, the role of forecast and warning, and of watershed management are reviewed. Sample success stories and lessons learnt related to hydrological extremes are given and policy implications discussed. [source]

CANDIDATE PERSISTENCE AND PERSONALITY TEST PRACTICE EFFECTS: IMPLICATIONS FOR STAFFING SYSTEM MANAGEMENT

PERSONNEL PSYCHOLOGY, Issue 2 2010
JOHN P. HAUSKNECHT
Candidates persist in selection settings for numerous reasons, prompting several concerns regarding staffing-system management. Predictors of the propensity to retest and personality test practice effects were investigated among a sample of 15,338 candidates who applied for supervisory positions (and 357 who repeated the selection process) over a 4-year period with a large organization in the service industry. Results reveal greater likelihood of retesting among internal candidates and overall evidence of small-to-moderate personality test practice effects. Compared to passing candidates who retested for various reasons, failing candidates pursued alternative response strategies upon retesting and generated dimension-level practice effects that reached .40 to .60, whereas passing candidates generally replicated their initial profiles. For several subscales, low initial scores were associated with practice effects that exceeded a full standard deviation. Implications for research, practice, and policy are discussed. [source]

Characterizing a Brownfields recreational reuse scenario using the Triad Approach,Assunpink Creek Greenways project

REMEDIATION, Issue 4 2003
James Mack
Since the early 1990s the U.S. government has been developing and implementing public policies that advance the redevelopment of brownfields, and the recent passage of the Small Business Liability Relief and Brownfields Revitalization Act (SBLRBRA) will significantly advance efforts to integrate environmental contamination mitigation and redevelopment. Experience has demonstrated that successful redevelopment requires the collection, analysis, and interpretation of environmental data in a timely and cost-effective manner in order to allow developers and lenders to efficiently use cleanup resources, develop response strategies that integrate cleanup with redevelopment, and support meaningful outreach to involved stakeholders. Recent advances in the science and technology of site characterization hold the promise of improved site characterization outcomes while saving time and money. One such advancement, the Triad Approach, combines systematic up-front planning with the use of a dynamic field investigation process and the generation of real time data to allow in-field decision making on sample location selection. This article describes an application of the Triad Approach to redevelopment of an urban greenway in Trenton, New Jersey. The Triad Approach, initiated through a partnership between the City of Trenton, New Jersey Department of Environmental Protection, New Jersey Institute of Technology, and the U.S. Environmental Protection Agency, demonstrated that this approach could accelerate the characterization of the 60-acre, 11-parcel project area. Environmental issues that were solved using the Triad Approach included the delineation of the extent of historic fill, determination of no further action for several areas of concern, detailed investigation of specific impacted areas and the acquisition of sufficient data to allow the city to make important decisions regarding remediation costs and property acquisition. © 2003 Wiley Periodicals, Inc.

Perception of a cetacean mass stranding in Italy: the emergence of compassion

AQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 6 2010
Giovanni Bearzi
Abstract 1The view that whales are malicious monsters has been pervasive throughout history. Conversely, the idea that these animals experience suffering has emerged only recently. One way of investigating perceptual, as well as behavioural, shifts is assessing general public reactions to mortality events involving wild, rare and charismatic animals. 2Here, the responses of 118 individuals to questions regarding the mass stranding of seven sperm whales (Physeter macrocephalus) along the Adriatic Sea coast of Italy in December 2009 are reported through interviews taken at the stranding site and in the direct proximity of the dead animals. 3When asked why the whales were stranded, 44.1% of the respondents suggested anthropogenic causes and 21.2% non-anthropogenic. The remaining 34.7% mentioned a generic ,disorientation' or stated they did not know. When asked how they felt about the whales, 68.6% expressed feelings of compassion or care towards the animals. Clearly non-compassionate attitudes accounted for only 4.1% of the sample. Finally, 21.2% expressed feelings that were ambiguous in terms of being suggestive of compassionate or non-compassionate attitudes, including 11.9% amazement, 4.2% deprecation and 5.1% powerlessness. 4These results are in stark contrast with information obtained from accounts of similar events that have occurred in historical times, up until the first half of the 20th century. For centuries, responses to cetacean live strandings,typically including killing and harming of the animals,were either utilitarian or characterized by feelings including fear and a desire to ,subjugate the beast', with no apparent concern for their suffering and death. 5It is concluded that attitudes towards whales,today strikingly revolving around sadness, compassion and a sense of loss,have changed dramatically over time, with a steep turnaround in the 1970/1980s. Full appreciation of the ongoing evolution in public perception can channel marine conservation efforts and assist in the design of response strategies to marine mammal strandings.

Single Crossing Properties and the Existence of Pure Strategy Equilibria in Games of Incomplete Information

ECONOMETRICA, Issue 4 2001
Susan Athey
This paper analyzes a class of games of incomplete information where each agent has private information about her own type, and the types are drawn from an atomless joint probability distribution. The main result establishes existence of pure strategy Nash equilibria (PSNE) under a condition we call the single crossing condition (SCC), roughly described as follows: whenever each opponent uses a nondecreasing strategy (in the sense that higher types choose higher actions), a player's best response strategy is also nondecreasing. When the SCC holds, a PSNE exists in every finite-action game. Further, for games with continuous payoffs and a continuum of actions, there exists a sequence of PSNE to finite-action games that converges to a PSNE of the continuum-action game. These convergence and existence results also extend to some classes of games with discontinuous payoffs, such as first-price auctions, where bidders may be heterogeneous and reserve prices are permitted. Finally, the paper characterizes the SCC based on properties of utility functions and probability distributions over types. Applications include first-price, multi-unit, and all-pay auctions; pricing games with incomplete information about costs; and noisy signaling games. [source]

Cholinergic and noncholinergic septal neurons modulate strategy selection in spatial learning

A Statistical Sediment Yield Prediction Model Incorporating the Effect of Fires and Subsequent Storm Events,

JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 3 2008
Jang Hyuk Pak
Abstract:, Alluvial fans are continuously being developed for residential, industrial, commercial, and agricultural uses in southern California. Development and alteration of alluvial fans need to consider the possibility of mud and debris flows from upstream mountain watersheds affected by fires. Accurate prediction of sediment yield (or hyper-concentrated sediment yield) is essential for the design, operation, and maintenance of debris basins to safeguard properly the general populace. This paper presents a model for the prediction of sediment yields that result from a combination of fire and subsequent storm events. The watersheds used in this analysis are located in the foothills of the San Gabriel Mountains in southern California. A multiple regression analysis is first utilized to establish a fundamental statistical relationship for sediment yield as a function of relief ratio, drainage area, maximum 1-h rainfall intensity and fire factor using 45 years of data (1938-1983). In addition, a method for multi-sequence sediment yield prediction under fire conditions was developed and calibrated using 17 years of sediment yield, fire, and precipitation data for the period 1984-2000. After calibration, this model was verified by applying it to provide a prediction of the sediment yields for the 2001-2002 fire events in southern California. The findings indicate a strong correlation between the estimated and measured sediment yields. The proposed method for sequence sediment yield prediction following fire events can be a useful tool to schedule cleanout operations for debris basins and to develop an emergency response strategy for the southern California region where plentiful sediment supplies exist and frequent fires occur.

Focused attention in anhedonia: A P3 study

PSYCHOPHYSIOLOGY, Issue 5 2000
Stephanie Dubal
Attentional and information processing impairments have been evidenced in nonclinical anhedonic subjects. However, the extent of attentional deficit has not been determined. We studied focused attention, the ability to reject irrelevant or distracting messages, in anhedonic nonclinical subjects. The event-related potentials and behavioral performances of anhedonic subjects were compared with those of control subjects during the Eriksen focused attention task (C.W. Eriksen & B.A. Eriksen, 1974); the task combined one compatible and one incompatible condition, the latter causing an interference. Anhedonic subjects exhibited a smaller P300 and slower reaction times than control subjects. Varying task conditions had different effects on anhedonic subjects and controls, suggesting that anhedonic subjects may have developed a conservative response strategy. In view of previous works, these results suggest that attentional impairment is not ascribed to specific processes, but may involve a more global deficit, that is, a resource allocation deficit.

Learning to Cooperate: Learning Networks and the Problem of Altruism

AMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 3 2009
John T. Scholz
We explore how two populations learn to cooperate with each other in the absence of institutional support. Individuals play iterated prisoner's dilemmas with the other population, but learn about successful strategies from their own population. Our agent-based evolutionary models reconfirm that cooperation can emerge rapidly as long as payoffs provide a selective advantage for nice, retaliatory strategies like tit-for-tat, although attainable levels of cooperation are limited by the persistence of nonretaliatory altruists. Learning processes that adopt the current best response strategy do well only when initial conditions are very favorable to cooperation, while more adaptive learning processes can achieve high levels of cooperation under a wider range of initial conditions. When combined with adaptive learning, populations having larger, better connected learning relationships outperform populations with smaller, less connected ones. Clustered relationships can also enhance cooperation, particularly in these smaller, less connected populations. [source]
