Abstract

The discrete element method (DEM) was used to stimulate creep processes in granular materials. The authors present the main features of the numerical model, which include a new viscous mechanism for particle sliding, a new feedback technique for maintaining constant stress during creep, and a scaling technique that allowed monitoring the long‐term creep behaviour of a granular assembly. The creep behaviour of the numerical model exhibited the essential characteristics of soil creep—a creep rate that decreased rapidly with time, an increase in the creep rate with the applied deviator stress, and the beginning of creep rupture. The model's numerical performance is discussed, and representative results are presented.

Abstract

Purpose: Grandparents are common providers of childcare within the Caribbean region. Yet research on the implications of grandparent caregiving for older adults’ well-being is limited. This study examined gender differences in the relationship between grandparent caregiving and the life satisfaction of older adults in Jamaica.

Methodology: Using a sample of 1,622 grandparents 60 years and older drawn from the 2012 study “The Health and Social Status of Older Jamaicans,” we estimated binary logistic regression models to examine the association between the frequency of grandparent caregiving and the life satisfaction of grandparents.

Findings: Grandmothers were more likely than grandfathers to provide care. We did not find a statistically significant gender difference in the life satisfaction of caregiving grandparents. Yet, gender differences in the patterns of association between grandparent caregiving and life satisfaction were evident. Among grandmothers, both occasional and regular caregiving was associated with higher life satisfaction relative to non-caregivers. Among grandfathers, however, only regular caregiving was positively associated with life satisfaction.

Originality: This is the first population-based study within the Caribbean to examine gendered patterns of grandparent caregiving and the association with grandparents’ well-being. The findings of this study suggest that grandparent caregiving is beneficial to the well-being of older Jamaican men and women. This study challenges assumptions of gender norms that typically do not position men to be involved in caregiving roles, and to derive satisfaction from such roles, within Caribbean households. The authors suggest more attention should be given to interventions to encourage men to be actively involved in family caregiving.

Abstract

Following the disasters of 9/11/01 the U.S. government has embarked on what is intended to be a comprehensive response to the hazard of further terrorist attacks on Americans at home and abroad. This paper addresses the homeland component of the response and asserts that both the general approach and the measures being deployed are neither comprehensive nor well-balanced. The broad goal of security is losing ground to the narrower objective of defense; mitigation strategies are being overshadowed by preparedness and response alternatives; expert systems are preferred over grass-roots bottom-up ones; and possibilities for reducing human vulnerability are being ignored in favor of programs that aim to reduce risks or lessen the vulnerability of built structures and infrastructures. Preferences for the use of sophisticated technologies that are intended to quarantine terrorism and minimize its consequences far outnumber efforts to engage with the messier realm of ideas and behaviors related to terrorism. Yet it is the latter that shape the public interpretation of terrorism risks, structure patterns of exposure and affect the coping capabilities of threatened communities. Without substantial changes to policy that take account of these deficiencies, Americans are likely to find themselves little better prepared to confront the challenges of future terrorist attacks on targets in U.S. territory and the nation’s ability to address other kinds of hazards may be seriously compromised.

Abstract

Stakeholder thinking has contributed considerably to the organizational literature by demonstrating the significance of the environment in managing organizations. Stakeholders affect and are affected by organizations’ daily operations and decisions. They have varied and often conflicting interests, making it necessary for managers and organizations to know who they are as well as their attributes. Consequently, Mitchell et al. (1997) developed the stakeholder salience theory to help managers and organizations identify the power of certain stakeholders and their salience to the organization. With a few exceptions, the mainstream stakeholder salience theory is in many ways still largely static, short-term oriented, and firm-centered. The aim of this paper is to revisit certain conformist assumptions concerning the role of marginalized stakeholders, or “dormant” stakeholders, in stakeholder thinking. Overall, this chapter is a call to a new conceptualization of stakeholders that reintroduces stakeholder dynamics at the core of stakeholder thinking to overcome its restrictive shortcomings. We argue that managing stakeholder relationships is not simply meeting stakeholder demands but also involves taking into account the long-term dynamics of stakeholder interactions.
