The Rate of Convergence of some Asymptotic Expansions for Distribution Approximations via an Esseen Type Estimate

Some asymptotic expansions not necessarily related to the central limit theorem are studied. We first observe that the smoothing inequality of Esseen implies the proximity, in the Kolmogorov distance sense, of the distributions of the random variables of two random sequences satisfying a sort of general asymptotic relation. We then present several instances of this observation. A first example, partially motivated by the the statistical theory of high precision measurements, is given by a uniform asymptotic approximation to (g(X + μ _n )) _n∈?, where g is some smooth function, X is a random variable and (μ _n ) _n∈? is a sequence going to infinity; a multivariate version is also stated and proved. We finally present a second class of examples given by a randomization of the interesting parameter in some classical asymptotic formulas; namely, a generic Laplace's type integral, randomized by the sequence (μ _n X) _n∈?, X being a Gamma distributed random variable.     

Resilience and Deviant Behavior Among Institutionalized Adolescents: The Relationship with Significant Adults

The transition to institutional care often implies the separation from a dysfunctional environment, marked by neglect, abandonment and lack of emotional responsiveness, which makes youth more vulnerable to the development of deviant behavior. The quality of the relationship established with significant figures within the institution as well as with teachers is suggested as a protective factor for the development of resilience and the detachment from deviant behaviour. The present study aims to test the predictive effect of the quality of relationship to institutional caregivers and teachers on the development of resilience and deviant behaviour in institutionalized adolescents. We also intend to test the mediating effect of resilience in the previous association. The sample was composed by 202 institutionalized adolescents, 12–18 aged (M = 14.96, SD = 1.80), and from both genders. Data were collected using self-report questionnaires. The results demonstrated that the quality of relationship with significant figures was positively associated with resilience and may play an important role in preventing deviant behaviour. There was also a total mediation effect of resilience on the association between quality of relationship with significant figures and development of deviant behaviour. The results suggest that the affective reorganization of institutionalized adolescents can be promoted by the establishment of safe havens, which reflect feelings of belonging and acceptance, facilitating a more adaptive experience.     

Board compensation and ownership structure: empirical evidence for Italian listed companies

This paper investigates the relationships among corporate ownership, the level of board compensation, and firms’ future performance within Italian listed companies. Board compensation could be related to corporate ownership characteristics, like the type of controlling shareholder, ownership concentration, the separation between cash flow and voting rights, and the presence of shareholders’ agreements. The evidence of high levels of board compensation associated with certain governance characteristics could signal, in a principal-agent framework, rent extraction by entrenched managers or by controlling shareholders versus minority shareholders; high board compensation, however, could be related to the need to hire directors with higher professional standing and also to the desire to create a network with other companies through the enlargement of the board, according to a social network view. In this paper we disentangle this issue showing the relationship between excess board compensation and future performance: examining firms listed on the Milan Stock Exchange over the period 1995–2002, we show that board compensation is linked to many governance characteristics, but excess compensation is never positively related to future performance. For founder family firms, in particular, high board compensation is associated with (a) smaller board size; (b) higher proportion of family members on the board; (c) lower future performance. The whole evidence therefore doesn’t support the hypothesis suggested by the social network view, but is consistent with a rent extraction hypothesis. These results could add new empirical evidence to the recent debate on the need for global remuneration reform. According to our results, some control mechanism and an increase in transparency of executive compensation schemes could be appropriate.     

A demand classification scheme for spare part inventory model subject to stochastic demand and lead time

In this study, we aim to develop a demand classification methodology for classifying and controlling inventory spare parts subject to stochastic demand and lead time. Using real data, the developed models were tested and their performances were evaluated and compared. The results show that the Laplace model provided superior performance in terms of service level, fill rate (FR) and inventory cost. Compared with the current system based on normal distribution, the proposed Laplace model yielded significant savings and good results in terms of the service level and the FR. The Laplace and Gamma optimisation models resulted in savings of 82 and 81%, respectively.     

Foreign direct investments in manufacturing by district firms: evidence from the Italian chair district

Manufacturing internationalisation is a phenomenon that currently involves several industrial districts. While the literature on industrial districts is wide, few works analyse the (manufacturing) internationalisation dynamics. This study tries to fill this lack by analysing forms, motivation, obstacles and results of the foreign direct investments carried out in one of the most important Italian districts. The research shows how some of the district leading firms have recently combined local presence with a strategy of internationalisation that also involves manufacturing activities through foreign direct investments. The readers can comprehend the main features of the international manufacturing path that is involving one of the most important Italian industrial districts, i.e. the chair district. The research offers a contribution to an area rather neglected in literature – the district (manufacturing) internationalisation dynamics.     

Building political competencies for the transformation of racism in Aotearoa

Abstract

In the face of enduring systemic racial disparities between Māori and non-Māori, we invite Pākehā health, education and social service professionals to review their ethical conduct and to enhance their political competencies to help transform racism. This paper examines how Pākehā became beneficiaries of racism and how libertarian discourses are used to distract attention away from the associated privileges. Based on experience in the anti-racism movement, we (the Pākehā authors) advocate for the grounding of Pākehā practitioners in a deeper understanding of colonial history. We invite closer attention to structural analysis as a means of gaining the understanding needed to strengthen political competence in order to avoid collusion with institutional racism. We make a case to develop co-intentional relationships with Māori through active whanaungatanga and the applications of the teachings of Freire as pathways for strengthened practice.     

Evolution and Dimensions of a Women's Clinic in a University Setting

Abstract

As theologian Henri Nouwen has pointed out, the opposite of love is not hate; it is fear. Nowhere is the fear which strips us of our capacity to behave rationally better evidenced than in relation to AIDS. Only as we allow ourselves to be moved from what Nouwen calls the house of fear into the house of love will responsible answers begin to be formulated to the emerging moral questions presented by AIDS. The questions are threefold. To those potentially at risk for AIDS or actually infected with it, it raises questions about honesty and love in sexual relations. For caregivers, it raises questions about the nature of our professional obligations. And for society at large, it raises questions about confidentiality and scapegoating. It is the author's contention that an experience of the divine love—unconditional, unmerited, unbounded—is alone sufficient to move us from fear, and its responses to AIDS, to a more loving (and courageous) stance. Only thus will we begin—whether as victims of AIDS, as caregivers, or as members of society at large—to exercise moral responsibility with respect to this dread disease.     

The Atlantic Slave Trade to Maranhão, 1680–1846: Volume,Routes and Organisation

Maranhão has the best documented slave trade in all Portuguese America. However, it is one of the least studied branches of the Atlantic slave trade. This article provides an assessment of the volume, routes and organisation of the slave trade to Maranhão, in northern Brazil. It shows that, although small in scale, the slave trade to Maranhão displayed important features concerning the routes and organisation of the Atlantic slave trade. Finally, because of the late European occupation and relative isolation, the slave trade to Maranhão offers ideal conditions for observing the rise and fall of African slavery in the New World.     

MALDITOS: STREET GANG SUBVERSIONS OF NATIONAL BODY POLITICS IN CENTRAL AMERICA

Since the mid-1980s, street gangs known as maras have emerged as a new social entity in Central America. In Honduras, these informal organizations are repeatedly represented in various forms of media as an aberration that is clearly separate from populace and state. Such representations render mareros as entities that possess a radically alien ontology, which is the sole locality of intervention of anti-mara programs. This article analyzes popular media and ethnographic observations to demonstrate that a) rather than being an alien ontology, marero subjectivities are co-constituted through nation and class-forming practices and b) despite such representations, Hondurans of various walks of life routinely subvert attempts to create a tripartite body politic of state-populace-marero. Continued emphasis on the marero as the sole site of intervention and rehabilitation deals with the mara issue at a symptomatic level and fails to address the quotidian processes that give form to this phenomenon.     

All Puerto Rico with Vieques: Mobilizing Support Through Social Skills and Field Dynamics

This article explains the success of All Puerto Rico with Vieques (TPRCV) in coordinating a broad-based coalition in support of the movement to remove the US Navy from Vieques. Considering the literatures on organizations, strategic fields and social movements, the analysis looks at how environmental conditions and the attributes of the leadership become relevant in the formation and sustainability of coalition work. The article argues that under the conditions of a vibrant political activist sector and a dynamic political field, TPRCV used accumulated social skills to take advantage of network intersection and frame adaptation. Though environmental dynamics may produce favorable conditions for coalition building, these will be limited to the capacity of the social actors to identify them, assimilate their potential and translate them into opportunities.
