Limited Access: Disparities in Flexible Work Schedules and Work-at-home

This research tests predictions regarding potential disparities among the employed by personal characteristics in the ability to vary the starting and ending times of their workday and engage in work from home. Women and African-Americans possess less access to flexible work schedules, even when controlling for most job characteristics. Married men have more access, but only if they are parents, and mothers only if they have pre-school-age children. Workers with part-time or long hours gain far greater access. Work-at-home is more common among women, the married and parents-thus, relatively more reflective of family demands. The results suggest where public and organizational policies could be focused to spread flexible work arrangements more toward those who both most value it and lack it.     

Nonconglomerative coherent conditional probabilities in statistical inference

Noteworthy connections among conglomerability, countable additivity and coherence are discussed in detail, reaching the conclusion that nonconglomerable conditional probabilities must not be doomed and play a significant role in statistical inference. Extended and updated version of a contributed paper presented at the International Conference on “Information Processing and Management of Uncertainty in knowledge-based systems”, IPMU 2004, Perugia, Italy.     

Statistical consulting at German universities: Results of a survey

The article presents the results of a survey on statistical consulting at German universities, where the survey focused on obtaining information on when, where and to whom statistical consulting is provided. We investigate the financial frame of the activity and question the advantages and disadvantages from a consultant’s point of view.     

Some preservation results of NBUC aging property with applications

This paper develops a new characterization of NBUC aging property, and investigates its preservation properties both under monotonic anti-star-shaped transformations and under the non-homogeneous Poisson shock models.     

Cognitive Risk Factors to the Development of Anxiety and Depressive Disorders in Adolescents

This exploratory study examines cognitive risk factors, anxiety sensitivity, and positive and negative affect, as related to the development of anxiety and depression. In a mailed survey, adolescents completed the Child Anxiety Sensitivity Index and the Positive and Negative Affectivity Scale. Previous research utilized the broad and unified variable of anxiety sensitivity as a predictor of anxiety. In this study, we separate and examine the four specific factors of anxiety sensitivity: mental incapacitation concerns, social concerns, disease concerns, and unsteady concerns, and relate it to specific anxiety disorders and depression. Results indicate good convergent validity and improved divergent validity when utilizing the four factors of anxiety sensitivity as compared to using it as one construct. Results also suggest: (1) OCD and GAD share numerous similarities and (2) the importance of the role of negative affectivity in anxiety and depression. Being aware of the components of anxiety sensitivity and how they relate to specific anxiety disorders can help a social worker when rendering a diagnosis. Part of the data presented in this article was from David A. Dia’s doctoral dissertation.     

Fengshui theory in urban landscape planning

The spatial configuration of urban landscapes results from cumulative interactions between human activities and the physical environment. Traditional philosophies and cultural legacies have had important influences on urban development and planning in East Asia. In Seoul, traditional land use practices based on ‘Fengshui’ have significantly contributed to human-mediated patterns of landscape changes, in addition to the role of the socio-economic background (development) and other human activities. The concept of Fengshui was originally founded upon people’s empirical cognition of natural landscape patterns. Recently, however, advanced economic development, westernization and urbanization have been rapidly altering the old traditions of the holistic landscape systems through changing urban planning practices. Since the type, scale, frequency, distribution and spreading pattern of environmental and human disturbances have been changed, a new paradigm for urban landscape planning is necessary to maintain the ecological and cultural integrity of landscapes in Korea. In this paper, we discuss recent concepts and methods of landscape ecology and urban planning from the viewpoint of Fengshui, the traditional land use patterns in Seoul, whose application has so far been restricted only to traditional land evaluation. We conclude that, to maintain the sustainability of the urban landscape, it is necessary to develop a new urban planning framework for the region that is based on the integration between landscape ecology principles with the traditional concepts of Fengshui.     

The Economic Partnership Agreements: Rationale,Misperceptions and Non‐trade Aspects

The European Union and the African, Caribbean and Pacific (ACP) countries entered a new era in 2008. The Cotonou trade regime and the WTO waiver legitimising it have expired, and the long anticipated, and much debated, move to Economic Partnership Agreements (EPAs) has begun. This article explains the background and analyses the ‘alternatives’ to EPAs, in order to tackle common misperceptions. Moving on from what has been the focus of debates, namely, the reciprocal liberalisation required under WTO rules, it sheds some light on the non‐goods trade aspects of EPAs which, while integral to economic policy, are inherently hard to quantify and often skimmed over in existing studies or addressed in ideological terms.     

Wann werden Ehen getrennt?

With regard to marriages, numerous studies have reported a time-dependent course of the dissolution rate, which is characterized by an initial rise and a subsequent decline after a couple of years. The article at hand discusses potential explanations for the correlation of marital duration and the risk of dissolution and examines them on the basis of the Family Survey 2000. The results indicate, among other things, that the concentration of childbirths in an early stage of marriage leads to a slow-down of the initial rise of the dissolution rate whereas it weakens its later decline as the stabilizing effect of shared children on marriage decreases when the children become older. There are significant differences with respect to the dependency of the dissolution risk on marital duration between the successive marriage cohorts, depending on the wife’s occupation, age at marriage as well as between couples who did vs. those who did not cohabitate before marriage. The results suggest that relationship-specific processes as well as changes of the marital preconditions resulting from the partners’ respective ages contribute to the explanation of the course of the dissolution rate.     

Moral sentiments and social choice

We examine the implications, for social choice, of individuals having an intrinsic sense of fairness. Taking the viewpoint that social justice reflects the moral attitudes of the constituent members, we analyze the effect of the intensity of the individual sense of fairness on the solution of Nash bargaining over random allocation procedures. We use a stylized model of university admission policies to illustrate our approach. We show that even if social policies are ultimately determined by the bargaining power of the different groups, a society whose members have a common notion of fairness tends to implement fairer admission policies when the intensity of the sense of fairness of individual members increases.

Linking Financial Strain to Marital Instability: Examining the Roles of Emotional Distress and Marital Interaction

Using a sample consisting of 4,997 married couples from the National Survey of Families and Households, individual emotional distress, the occurrence of couple disagreements, couple fighting, and couple quality time together mediated the relationship between financial strain and personal assessments of marital instability. The overall results suggest that financial strain influences both positive and negative forms of couple interaction which are stronger mediators than personal emotional distress of the relationship between financial strain and marital instability. The results further suggest that there were no gender differences among these linkages.
