Bivariate deconvolution with SIMEX: an application to mapping Alaska earthquake density

Constructing spatial density maps of seismic events, such as earthquake hypocentres, is complicated by the fact that events are not located precisely. In this paper, we present a method for estimating density maps from event locations that are measured with error. The estimator is based on the simulation–extrapolation method of estimation and is appropriate for location errors that are either homoscedastic or heteroscedastic. A simulation study shows that the estimator outperforms the standard estimator of density that ignores location errors in the data, even when location errors are spatially dependent. We apply our method to construct an estimated density map of earthquake hypocenters using data from the Alaska earthquake catalogue.     

Standardisierungspotentiale lebenszyklusbasierter Modelle des strategischen Kostenmanagements

Tremendous increases in indirect costs can be found in many industries. Consequently, life cycle cost analysis models are getting more important in strategic cost management. However, existing models differ significantly from each other as they have been developed mainly for specific applications. In order to enable a common use of those models, a standardization of these models is required. We examine the potentials of standardizing models for life cycle cost analysis. In a first step, requirements regarding a standard model are derived from literature. As a second step, existing approaches found in literature are compared to the afore derived demands and it is analyzed to what extent they match the standardization requirements. Based on this comparison, we identify and discuss avenues for further research.     

The social relations of bereavement in the Caribbean

The objectives of this article are to discuss the various types of behaviors associated with grief and bereavement, and to examine the relationships, consequences, and outcomes of bereavement practices among the various religious and ethnic groups in the English-speaking Caribbean Islands of Jamaica, Trinidad, Grenada, and Barbados. The rituals associated with death and grief differs across cultures and is greatly influenced by religious beliefs and traditions. How these rituals are played out depend on the culture of origin and level of acculturation of the various groups into mainstream society. In the Caribbean region, expressions of grief represent religious and cultural traditions that may have a significant impact on social relations, particularly in multi-ethnic and multicultural societies. In the English-speaking Caribbean Islands of Jamaica, Trinidad, Grenada, and Barbados, mourning follows the patterns of traditional religious practices which have remained consistent over time. While families and friends may offer social support before and after burial or cremation, the social aspects of bereavement may also have implications for inter-group relations. Insights into bereavement practices and what it holds for ethnic and religious groups in contemporary Caribbean are presented.     

Supporting Disadvantaged Young People into Work: Insights from the Capability Approach

The Capability Approach (CA) offers a perspective on the employment activation of young people that is concerned with their freedom to make choices that they value rather than focusing solely on outcomes, such as having to take any job. It incorporates empowerment and the individual and external conversion factors that influence the conversion of resources into functionings for young people, such as getting a job that they value. This article considers the implications of using the CA as a lens for analyzing youth activation polices. A more capability informed approach to employment activation would not measure success solely by the transition into work, but rather by whether it has improved the young person's capabilities, and might focus, for example, on more sustainable and valued careers and develop individuals' freedom of choice in the labour market. Using data from two UK case studies of third sector organizations that support young people into work, it explores these issues empirically, including the extent to which these employment activation programmes, in their current form, can enhance the capabilities of beneficiaries. Conclusions on the implications of a CA for employment activation are made.     

The spatial distribution of smoking violations on a no-smoking campus: Implications for prevention

ABSTRACT

Objective: The present study extends research on campus smoking bans by examining where smokers are violating the policy at a large university in the southeastern region of the United States. Participants: The data collection was conducted by one graduate student from the university in August of 2014. Methods: A global positioning system device was used to collect the geo-coordinates of littered cigarette butts as a proxy measure for smoking violations. Results: A hot spot analysis found a number of spatial concentrations on campus, largely around classroom and administrative buildings along with parking lots and garages. Conclusions: The implications of such findings can direct enforcement to target these areas in order to reduce offenses and fulfill the initial goals of policy-makers and university administrators who support smoke-free campuses.     

Factorial Invariance of the Indecision Scale of the Career Decision Scale: A Multigroup Confirmatory Factor Analysis

Results of a multigroup confirmatory factor analysis (N= 686) indicated factorial invariance of a 3‐factor model of the Indecision scale of the Career Decision Scale (CDS; Osipow, Carney, Winer, Yanico, & Koschier, 1976 ). Differential item function was not observed when ΔCFI (comparative fit index) was used for comparison of models, thus indicating strong measurement invariance across gender. Men had significantly greater latent means for all 3 dimensions of career indecision. Given the multidimensional structure, use of the CDS may provide an initial step to help practitioners identify possible factors that are responsible for a client's career indecision. Clients may need assistance for initiating a career search, information to help them identify career possibilities for a chosen major, or detailed information concerning several possible careers that are under consideration.     

Multimedia Biographies: A Reminiscence and Social Stimulus Tool for Persons with Cognitive Impairment

The multimedia biography tells the story of the life of an elderly person with a cognitive impairment in motion picture format. The multimedia biography combines family photographs, film clips, audio narration, and music. It is intended to be screened on an ongoing basis to provide spaces for reminiscence and communication between cognitively impaired persons and their families. Using a production process in which we collaborated with family caregivers, we created 12 multimedia biographies for persons having Alzheimer's disease or mild cognitive impairment. This article describes our production and screening processes. We also share lessons learned from the multimedia biography research to assist practitioners, families, or researchers who wish to use similar technologies and processes for eliciting and sharing life stories.     

The Family Outreach Model: Tools for Engaging and Working With Families in Distress

The purpose of this article is to present a family intervention model to family service providers that builds on previous research in areas of social support and family problem solving. The Family Outreach Model provides a set of strategies for engaging and working with families in five phases of family coping at different points in time in the family's life. The strategies reflect intentional choices by family service providers about both collaborative and directive styles of therapeutic alliance and highlights ways to determine which style best fits with what specific families want and need, depending on the manner of family coping that it is using. Implications for programs and public policy are presented.     

The Usefulness of Social Capital Theory for Understanding the Academic Improvement of Young Children in Stepfamilies Over Two Points in Time

Data from the nationally representative Early Childhood Longitudinal Survey, Kindergarten Class of 1998–1999 (ECLS–K) involving more than 300 children residing in stepfamilies from kindergarten through 5th grade were used to test the usefulness of social capital theory for understanding the academic improvement of young children over 2 points in time. For change scores in reading, the model explained 34% of the variance and for math, 33% of the variance. Findings are summarized in light of implications for stepparents, researchers, and policymakers.     

WHEN YOU JUST CANNOT GET AWAY

The continuing evolution of information and communication technologies (ICTs), such as Internet-connected computers and cellular phones, provides a means for increased work/home permeability and for current work/home boundaries to be redefined as workers can potentially be accessible by employers and family/friends at all times. This transformation of work/home boundaries can open the individual to increased levels of negative spillover, wherein aspects of one role negatively impact or impede upon another. This investigation uses data from the Work-Life and Technology Use Survey to determine if ICT use plays a role in defining work/home boundaries and serves as a significant predictor of negative spillover in both the work-to-home and home-to-work directions. Results show that frequency of engaging in ICT-related activities (e.g. checking email and using Facebook) is associated with negative spillover in both directions, suggesting that ICTs may play a significant role in facilitating negative work/home spillover.
