“Infiltrators” or Refugees? An Analysis of Israel's Policy Towards African Asylum-Seekers

This article adopts a genealogical approach in examining Israeli immigration policy by focusing on the situation confronting African asylum seekers who have been forced back into Egypt, detained and deported but who have not had their asylum claims properly assessed. Based on immigration policies formulated at the time of Israeli independence, whose principle objective was to secure a Jewish majority state, we argue that Israel's treatment of African asylum seekers as ‘infiltrators’/economic migrants stems from an insistence on maintaining immigration as a sovereign issue formally isolated from other policy domains. Such an approach is not only in violation of Israel's commitment to the Refugee Convention, it directly contributes to policies which are ineffective and unduly harsh.     

Information,Interactivity, and Social Media

The aim of this paper is to provide a conceptual theoretical framework to the term “social” in a social media context. This is done by exploring the relationship between three central terms in a social media environment: information, interactivity, and sociability. We suggest a model that describes the relations between these terms in a social media context. As the model suggests, information is the basic unit of a communication process, but social media users are the ones that decide whether and how much information to share, and when and whether to comment on a social media platform. Hence, not solely the technological features of a platform determine its level of interactivity and sociability, but the actual performances of its users.     

Just-in-time scheduling with controllable processing times on parallel machines

We study scheduling problems with controllable processing times on parallel machines. Our objectives are to maximize the weighted number of jobs that are completed exactly at their due date and to minimize the total resource allocation cost. We consider four different models for treating the two criteria. We prove that three of these problems are NP\mathcal{NP} -hard even on a single machine, but somewhat surprisingly, the problem of maximizing an integrated objective function can be solved in polynomial time even for the general case of a fixed number of unrelated parallel machines. For the three NP\mathcal{NP} -hard versions of the problem, with a fixed number of machines and a discrete resource type, we provide a pseudo-polynomial time optimization algorithm, which is converted to a fully polynomial time approximation scheme.     

Smartphones and young publics: A new challenge for public relations practice and relationship building

This study focuses on smartphones and their potential contribution to relationship building, between organizations and young publics. A survey among a representative sample of 550 young, Israelis, aged 21–31, and sixty personal in-depth interviews with undergraduate students were, conducted. The findings reveal that the smartphone satisfies both interaction-related and cognitive-related, needs, but organizations do not utilize the dialogic potential of the smartphone to engage and, to build relationships with young publics.     

Recognizing difference: in/visibility in the everyday life of individuals with facial limb absence

People who lack part(s) of their face have a visibly different appearance both due to their facial difference itself and the medical aids that they use to cover it (e.g. prostheses, bandages). In this article, we draw on interviews with affected individuals in order to investigate how visible difference features in their everyday experience. The visibility of their facial difference, we show, comes into play as they interact with various others in the contexts of their daily life. However, respondents’ visibility manifests in different ways, depending on whether they cover or uncover their facial difference. These different modes of visibility make for distinct ‘visibility experiences’, as participants meet others who notice – or fail to notice – their atypical appearance. By exploring these experiences, our article provides insights into the role of visibility in interviewees’ everyday life, and demonstrates how they actively negotiate their social recognition within encounters with various others.     

Finite-Sample Properties of Some Alternative GMM Estimators

We investigate the small-sample properties of three alternative generalized method of moments (GMM) estimators of asset-pricing models. The estimators that we consider include ones in which the weighting matrix is iterated to convergence and ones in which the weighting matrix is changed with each choice of the parameters. Particular attention is devoted to assessing the performance of the asymptotic theory for making inferences based directly on the deterioration of GMM criterion functions.     

Evaluating Cooperative Game Theory in water resources

Two empirical applications of Cooperative Game Theory concerned with regional cooperation in the use of irrigation water are presented. Both studies attempt to derive income maximizing solutions for the participants and the related income allocation schemes. Distinction is made between transferable and non-transferable utility situations. The reasonableness and the acceptability of the schemes derived are later critically evaluated. Main findings are: (1) use of utility functions leads to problems in gains allocations, (2) the Core concept may be useless in this application because since it is either difficult to calculate or is empty in many cases, (3) gains allocation and the derived core are heavily dependent on probabilities of coalitions formation in the Shapley value or the Generalized Shapley Value.During the course of this research in The Hebrew University of Jerusalem.On leave from The Hebrew University of Jerusalem.     

Comment on “The Law of Large Demand for Information”

Say that one information structure is eventually Blackwell sufficient for another if, for every large enough n, an n‐sample from the first is Blackwell sufficient (Blackwell (1951, 1954)) for an n‐sample from the second. This note shows that eventual Blackwell sufficiency lies strictly between (one‐shot) Blackwell sufficiency and the ordering of information structures formulated by Moscarini and Smith (2002), and thus offers a new criterion for comparing experiments. A characterization of eventual Blackwell sufficiency in terms of the one‐shot experiments remains an open question.
