Dimensions et effets des activités informelles dans une très petite économie

Les auteurs évaluent l'emploi informel – et les revenus non déclarés qu'il engendre – dans une très petite économie à gouvernance médiocre. Les données d'une enquěte auprès des ménages et d'un recensement leur servent à estimer le nombre de travailleurs en emploi informel à Chypre‐Nord, ainsi que les caractéristiques de cet emploi, entre 2004 et 2011. Les travailleurs concernés sont essentiellement des citoyens non affiliés à la sécurité sociale, des immigrés employés illégalement ou des personnes ayant deux emplois dont un non déclaré. L'économie informelle aurait représenté 9,1 pour cent du PNB en 2006, et 12,2 en 2011.     

Inference in multivariate linear regression models with elliptically distributed errors

In this study we investigate the problem of estimation and testing of hypotheses in multivariate linear regression models when the errors involved are assumed to be non-normally distributed. We consider the class of heavy-tailed distributions for this purpose. Although our method is applicable for any distribution in this class, we take the multivariate t-distribution for illustration. This distribution has applications in many fields of applied research such as Economics, Business, and Finance. For estimation purpose, we use the modified maximum likelihood method in order to get the so-called modified maximum likelihood estimates that are obtained in a closed form. We show that these estimates are substantially more efficient than least-square estimates. They are also found to be robust to reasonable deviations from the assumed distribution and also many data anomalies such as the presence of outliers in the sample, etc. We further provide test statistics for testing the relevant hypothesis regarding the regression coefficients.

Genetic algorithms for optimization of a mine system under uncertainty

The production planning of a mine system associated with mining, processing and refining stages dictates to determine optimal system parameters such as optimal production rates, location of refining facility and the best reconstruction time of production rates. This paper proposes a combination of the chance constrained programming (CCP) and the genetic algorithms (GA) to find the optimal system parameters simultaneously. In generic form the problem is expressed as the maximization of net present value of future cash flows such that the capacity constraint and predefined specifications are satisfied. The blending requirements expressed in the CCP are transformed into deterministic equivalents. A new form of the problem is solved by the GA. The approach was demonstrated on extraction, processing and refining of four iron ore mines with varying reserves, ore qualities, geological and topographic conditions, four mineral processing units and one refining facility. The results showed that the proposed algorithm could be used to determine optimal production rates, the facility location and the best reconstruction time.     

Evaluation of the relationship between compliance with the follow-up and treatment protocol and health literacy in bladder tumor patients

Abstract

Objective: To investigate the relationship between the compliance of bladder cancer patients with cystoscopic follow-up and the treatment protocol, and their health literacy.

Methods: Patients who underwent transurethral resection surgery for bladder tumor were found to have non-muscular invasive bladder carcinoma on pathology examination and then underwent cystoscopic follow-up for 1?year or more were included in the study. Cystoscopic follow-up was recommended to the low- and high-risk groups in terms of progression and recurrence. The patients were evaluated with the Health Literacy Survey-European Union scale.

Results: The mean age of the patients was 67.13?±?10.77 years. The treatment continuity rate was 80.50% (n?=?33) in the adequate health literacy group (n?=?41) and significantly higher than the 56.50% (n?=?48) rate in the inadequate health literacy group (n?=?85) (p?=?.008). The health literacy results revealed that the health promotion and general index score was higher in the group of patients under the age of 65.

Conclusions: Adequate health literacy in bladder cancer patients is associated with better compliance with the treatment protocol. Young patients show better compliance with the follow-up protocol recommended by the physician. Increasing the follow-up protocol compliance of elderly patients with inadequate health literacy is necessary.     

Model,Event, Context: Globalization,Arab Social Movements,and the Modeling of Global Order

In this article I scrutinize a particular discursive strategy that attempts to straightjacket the new social movements in the Arab uprisings. Rather than being open to new forms of polities and alternative modes of economic and social organization, an emerging governmental and scholarly discourse calls for a model of development for the Arab world. I argue that this model limits political imagination; and that it is the effect of a late modern logic that seeks to impose a particular form of politics in global political life. In, and through, the language of an archetype, these social movements, and the emerging polities, are being tamed to inherit the tensions and fragilities of a certain form of political and economic globalization.

En este artículo examino detalladamente una estrategia particularmente divagadora, que trata de restringir los nuevos movimientos sociales en los levantamientos árabes. En vez de abrirse a nuevos sistemas de gobierno y medios alternativos de organización económica y social, un planteamiento de gobierno emergente y académico exige un modelo de desarrollo para el mundo árabe. Sostengo que este modelo limita la imaginación política y que es el efecto de una lógica moderna tardía que busca imponerse a una forma particular de política en la vida política global. Estos movimientos sociales y los sistemas de gobierno nacientes dentro y a través del lenguaje de un arquetipo, se han domado para heredar las tensiones y fragilidades de cierta forma de globalización política y económica.

本文中,我详细审视了一种特定的话语策略,它试图严格限定阿拉伯起义中的新社会运动。 一套新近兴起的政府和学术话语呼吁阿拉伯世界的发展模式,而非对新形式的政体及替代性经济和社会组织模式开放。我认为,这种模式限定了政治想象力,它是试图在全球政治生活中强加一种特定政治形式的晚期现代逻辑作用的结果。在原始类型的语言中,或通过这种语言,这些社会运动及新兴政体正被驯服,以继承某种形式的政治和经济全球化的紧张与脆弱。     

The Duality of an Atypical Leader in Diversity Management: The Legitimization and Delegitimization of Diversity Beliefs in Organizations

An atypical leader is often celebrated as an individual who is likely to support workforce diversity in organizations. Yet the verity of the assumption that an atypical leader will invariably promote workforce diversity remains underexplored. In this paper, we question this assumption and demonstrate the dualities of an atypical leader in legitimizing and delegitimizing workforce diversity. We define and examine the concept of atypicality among leaders, in terms of how they emerge, who they are (dispositions), what they say (discourses) and what they do (performative acts). We introduce a conceptual framework that maps out the emergence and constitution of an atypical leader, as well as their impact on diversity management within an organization. Our analysis incorporates the concept of habitus (class‐specific and reflexive), in order to reveal the dualities of an atypical leader which determine the management of diversity within an organization and cause continuity and change in diversity beliefs.
