The Quantitative Estimation of IT‐Related Risk Probabilities

How well can people estimate IT‐related risk? Although estimating risk is a fundamental activity in software management and risk is the basis for many decisions, little is known about how well IT‐related risk can be estimated at all. Therefore, we executed a risk estimation experiment with 36 participants. They estimated the probabilities of IT‐related risks and we investigated the effect of the following factors on the quality of the risk estimation: the estimator's age, work experience in computing, (self‐reported) safety awareness and previous experience with this risk, the absolute value of the risk's probability, and the effect of knowing the estimates of the other participants (see: Delphi method). Our main findings are: risk probabilities are difficult to estimate. Younger and inexperienced estimators were not significantly worse than older and more experienced estimators, but the older and more experienced subjects better used the knowledge gained by knowing the other estimators' results. Persons with higher safety awareness tend to overestimate risk probabilities, but can better estimate ordinal ranks of risk probabilities. Previous own experience with a risk leads to an overestimation of its probability (unlike in other fields like medicine or disasters, where experience with a disease leads to more realistic probability estimates and nonexperience to an underestimation).     

The Impact of Perceived Discrimination and Immigration Policies Upon Perceptions of Quality of Life Among Latinos in the United States

This study examined the impact of enforcement of US immigration policies and perceived discrimination on perceptions of quality of life for Latinos in the US. Data for this study were drawn from the 2007 Pew Hispanic Center survey of 2,000 Latino adults living in the US. Multinomial logistic regressions indicated that participants who had higher levels of perceived discrimination and who were personally affected by US immigration enforcement also perceived the following: (1) life was more difficult now for Latinos than in the past; (2) higher levels of fear of deportation for themselves or a loved one; (3) the lives of Latino children will be worse in the future; and (4) a lower quality of life for themselves. Female participants and participants with more years in the United States, and higher levels of linguistic acculturation generally had fewer issues regarding immigration policies or had a more positive outlook for Latinos in the United States.     

Engineer-to-order (ETO) production planning and control: an empirical framework for machinery-building companies

This paper illustrates the results of an empirical study involving 21 engineer-to-order (ETO) companies, operating in the machinery-building industry. The study investigates the needs and requirements of such companies in terms of software support for governing the businesses, with particular emphasis on production planning and control (PPC) processes. An empirical analysis investigated two main aspects: (i) the set of business activities performed by the companies in the analysed industry and (ii) the relevant, high-level software functionalities required for the execution of such activities. As an answer to the observed compelling need for reviewing the general approaches to PPC in machinery-building companies, we develop an empirical, high-level production planning and scheduling reference framework, encompassing all the activities involved in the order fulfilment process.     

A note on convergence rates for posterior distributions via large deviations techniques

This paper provides rates of convergence for a class of posterior distributions which are exchangeable with respect to a tree of partitions. The derivations rely on large deviations techniques.     

Dyadic Research in Marriage and Family Therapy: Methodological Considerations

With training that emphasizes relationship systems, marriage and family therapists are uniquely attuned to interpersonal dynamics, interdependence, and the influence of relationships on individuals’ perceptions, beliefs, and attitudes. While recent statistical advances have contributed to a proliferation of resources designed to introduce researchers to dyadic data analysis, guidelines related to the methodological aspects of dyadic research design have received less attention. Given the potential advantages of dyadic designs for examining couple and family relational and therapeutic processes, the purpose of this article is to introduce marriage and family therapy researchers to dyadic research methodology. Using examples from our own research, we discuss methodological considerations and lessons learned related to sampling, measurement, data collection, and ethics. Recommendations for future dyadic research are provided. Video Abstract     

History of Research on Process Relevant to Clinical Social Work

Case study research methods and holistic approaches have not appeared in the social work literature for at least two decades due to debate over what constitutes legitimate science. This debate has contributed to alienation of the work of the researcher and the day-to-day practice of the practitioner. Existing intellectual frameworks and measuring tools for understanding clients’ reactions and behaviors through case study research methods can help close the gap between researcher and practitioner. The purpose of this article is to provide a historical review highlighting certain tensions in the field of social work and to provide the foundation for a discussion of the contemporary state of process research—whereby new theory and methods from the natural sciences tender means for the field to pick up where previous process researchers have left off. The article concludes with recommendations for future work and anticipates novel and useful methods for process research.
