Ex Ante versus Ex Post Optimal Promotion Rules: The Case of Internal Promotion

A firm deciding on its promotion practices will be concerned both with the efficient assignment of workers to tasks and with rewarding prior performance. This can result in a time-inconsistency problem because the promotion rule that is optimal at the time of the promotion decision may differ from the rule that is optimal before performance is determined. In this article I explore the role of time inconsistency in determining promotion practices. In particular, I show that the common practice of favoring internal candidates for promotion can be understood as a response by firms to the problem of time inconsistency.     

Conceptualizing and Measuring Financial Resilience: A Multidimensional Framework

Financial inclusion has become a policy priority. For many countries, this has meant focusing on the delivery and practical aspects of financial products and services. This paper argues that this approach is not sufficient to improve financial wellbeing more broadly. It suggests a more comprehensive approach moving away from asking whether people are excluded or not to asking whether they have access to accessible, acceptable and appropriate resources and supports in adverse financial circumstances. A better understanding of individuals’ financial resilience: how they bounce back from adverse financial events and the resources and supports they draw on; could help determine where resources can and should be invested to assist people to cope with financial adversity, assist the development of effective policy and, ultimately, improve financial wellbeing. This paper puts forward a definition of financial resilience and a methodology for measuring it. Australia is used as a case country from which to draw conclusions using a survey of 1496 representative adults (18+). The findings indicate that over 2 million Australian adults experienced severe or high levels of financial vulnerability raising very real concerns about financial wellbeing. Implications for academics and policy makers are presented.

     

MARKET STRUCTURE AND MEDIA DIVERSITY

We estimate a mixed logit model of the demand for local news service. Results provide evidence that suggest the representative consumer values more diverse news, more coverage of multicultural issues, and more information on community news, and has a distaste for advertising. Demand estimates are used to calculate the impact on consumer welfare from a marginal decrease in the number of independent television stations that lowers the amount of diversity, multiculturalism, community news, and advertising. Consumer welfare decreases, but the losses are smaller in large markets. For example, small‐market consumers lose $45 million annually while large‐market consumers lose $13 million.

Fostering Environmental Integration in Public Aid: Influence of Interactions Between Environmental NGOs and Aid Donors

In order to ensure sustainable development, aid donors need to improve the environmental effectiveness of their whole activity. This improvement seems to be influenced by their interactions with environmental NGOs (ENGOs). Faced with a diversity of interactions between these two kinds of actors, a strategic typology is proposed here to describe this multiplicity and, by doing so, to consider their environmental impact. Four relational postures have been identified: (i) external advocacy and (ii) the cooperation–criticism focus on the antagonistic link that exists between environment and development; (iii) environmental collaboration, and (iv) service provision, which focus on synergies that can exist between environment protection and development issues. Win–win solutions need to be continuously sought and enhanced. However, ENGOs and donors are called to recognize the necessity of maintaining a critical position in actors’ interactions vis-à-vis the implementation of development activities that are detrimental for the environment.     

Review of Chinese sex attitudes & applicability of sex therapy for Chinese couples with sexual dysfunction

Although sex therapy techniques have widely been used to help Western couples with sexual dysfunction, there has been little research on the applicability of these techniques among Chinese couples. This article discusses the Chinese views and concepts of sex and sexual dysfunction in the past and present, culturally bound sexual problems, and gender role stereotypes. We suggest that with careful integration of the therapeutic techniques with Chinese sex concepts, sex therapy can be applied to Chinese couples experiencing problems in sexual functioning.     

The choice among past trends as a basis for the prediction of future trends in old-age mortality

We explored the extent to which projections of future old-age mortality trends differ when different projection bases are used. For seven European countries, four alternative sets of annual rates of mortality change were estimated with age–period log-linear regression models, and subsequently applied to age-specific all-cause mortality rates (80+) in 1999 to predict mortality levels up to 2050. On average, up to 2050, e80 is predicted to increase further by 2.33 years among men and 4.03 years among women. Choosing a historical period of 25 instead of 50 years results in higher predicted gains in e80 for men but lower gains for women. Choosing non-smoking-related mortality instead of all-cause mortality leads to higher gains for women and mixed results for men. In all alternatives there is a strong divergence of predicted mortality levels between the countries. Future projections should be preceded by a thorough study of past trends and their determinants.     

The densest <Emphasis Type="Italic">k</Emphasis>-subgraph problem on clique graphs

The Densest k-Subgraph (DkS) problem asks for a k-vertex subgraph of a given graph with the maximum number of edges. The problem is strongly NP-hard, as a generalization of the well known Clique problem and we also know that it does not admit a Polynomial Time Approximation Scheme (PTAS). In this paper we focus on special cases of the problem, with respect to the class of the input graph. Especially, towards the elucidation of the open questions concerning the complexity of the problem for interval graphs as well as its approximability for chordal graphs, we consider graphs having special clique graphs. We present a PTAS for stars of cliques and a dynamic programming algorithm for trees of cliques. M.L. is co-financed within Op. Education by the ESF (European Social Fund) and National Resources.

VIOLENCE OR DISCIPLINE? WORKING WITH MULTICULTURAL COURT-ORDERED CLIENTS

Therapists working with court-ordered clients from cultures differing from the mainstream face challenging issues of compulsory therapy in the context of cultural diversity. This article reviews the literature on court-ordered and multicultural counseling, highlighting central elements of both. It then suggests guidelines that blend these elements. The author illustrates how using these guidelines can enable therapists to engage these clients in the therapeutic process and focus on culture as the context for change.     

Best practice in human rights education: The SHR Sport and Human Rights Olympics

Effective teachers differentiate their instruction to ensure that content is delivered to students in a way that is accessible and engaging. The differentiation of instruction in core classes such as math and English is becoming commonplace in education faculties across the United States. But what does ‘differentiated’ human rights education look like? This summary of a good practice describes the School for Human Rights Olympics that were held at the school in 2006. It was a unique activity—a new approach to teaching youth about human rights and a welcome move away from violation‐centered lessons.
