The aim of this article is to obtain a simple and efficient estimator of the index parameter of symmetric stable distribution that holds universally, i.e., over the entire range of the parameter. We appeal to directional statistics on the classical result on wrapping of a distribution in obtaining the wrapped stable family of distributions. The performance of the estimator obtained is better than the existing estimators in the literature in terms of both consistency and efficiency. The estimator is applied to model some real life financial datasets. A mixture of normal and Cauchy distributions is compared with the stable family of distributions when the estimate of the parameter α lies between 1 and 2. A similar approach can be adopted when α (or its estimate) belongs to (0.5,1). In this case, one may compare with a mixture of Laplace and Cauchy distributions. A new measure of goodness of fit is proposed for the above family of distributions.

AbstractWe consider a cooperative game defined by an economic lot-sizing problem with heterogeneous costs over a finite time horizon, in which each firm faces demand for a single product in each period and coalitions can pool orders. The model of cooperation works as follows: ordering channels and holding and backlogging technologies are shared among the members of the coalitions. This implies that each firm uses the best ordering channel and holding technology provided by the participants in the consortium. That is, they produce, hold inventory, pay backlogged demand and make orders at the minimum cost of the coalition members. Thus, firms aim at satisfying their demand over the planing horizon with minimal operation cost. Our contribution is to show that there exist fair allocations of the overall operation cost among the firms so that no group of agents profit from leaving the consortium. Then we propose a parametric family of cost allocations and provide sufficient conditions for this to be a stable family against coalitional defections of firms. Finally, we focus on those periods of the time horizon that are consolidated and we analyze their effect on the stability of cost allocations.

We studied the stylistic features of autobiographical memory structure which can be significant for the understanding the sources of intrapersonal propensity for deviant behavior among young people. From the standpoint of the Vygotsky's theory we studied 102 "parent-teenager" dyads in order to examine the mechanisms of cultural determination of autobiographical memory macrostructure in context of reproducing the life scenarios. We differentiate the social influences of various levels on the formation of system characteristics of autobiographical memory, which constitute individual style of fixation personal stories of the past. We have found а stable family-reproduced indicators of autobiographical memories belonging to the "family life" scenario, these include the emotional profile of the memories of lives, the level of scenario (fixation of socially approved events); representation of memories of other people (social orientation). The low values of these indicators can be the risk factors for asocial behavior.

Kin recognition is a phenomenon with an important function in maintaining cohesive social groups in animals. Several studies have examined parent–offspring recognition in species with direct parental care. Few studies have, however, explored parent–offspring recognition in animals that, at best, only show apparent indirect parental care, such as some reptiles. In this study, we investigated reciprocal parent–offspring recognition in the fossorial amphisbaenian Trogonophis wiegmanni, a viviparous species that shows potential stable ‘family groups’ in the form of parent-offspring long-term associations. We examined whether adult males and females could discriminate via chemical cues between familiar juveniles which associate with them within their family groups, and are potentially their offspring, to that of unfamiliar juveniles, and whether juveniles could discriminate between familiar adult males and females of their family group (probably their parents) and unfamiliar unrelated adults. We measured tongue flick behavior to study chemosensory responses to the scent of conspecifics. We found that adult female amphisbaenians, but not males, could discriminate between scents of familiar and unfamiliar juveniles. Juvenile amphisbaenians did not discriminate between familiar and unfamiliar adult females, but recognize familiar from unfamiliar males. We discuss our results of parent–offspring recognition according to its potential social function in an ecological fossorial context where visibility is limited and chemosensory kin recognition may contribute to the establishment of stable family groups.

Isites for the introduction of the fuzzyprobabilistic approach in the construction of mathematical models in personality psychology. The specificity of this field of psychology lies in the impossibility of constructing effective mathematical models by deterministic methods, including statistical ones. The fact is that statistical methods are intended for processing a variety of initial data and are used successfully in social psychology, which describes the trends of a certain phenomenon of a group of people «in general and in the middle», but are not applicable to an individual personality. The main position of the authors is the need to use the knowledge and experience of highly qualified specialistspsychologists who practice direct counseling of clients to solve personal psychological problems. The proposed apparatus for constructing fuzzy probability models is presented in the form of an algorithm that describes all the necessary steps – from working with an expert to interpreting models and using them to obtain qualitatively new information about the client's psychological state. The application of the fuzzyprobability approach is illustrated by the example of the synthesis of a mathematical model for assessing and predicting the psychological state of a woman's readiness to create a stable family

To Receive

When is a liberal democratic state justified in enforcing an educational policy on its citizenry? This question is especially relevant in contexts where religious minorities wish to receive exemptions from mandatory educational policies. Parents in such groups argue that these educational demands threaten the traditional ways of life of their communities, infringing on their parental right to raise their children as they see fit. Parents may also claim that their free exercise rights, as granted by the First Amendment, are violated by an educational policy that requires them to breach a religious command specifying a certain type of religious upbringing for their children. The customary way that both the courts and commentators have addressed this issue is to represent it as a conflict among four divergent interests: 1) The child’s interest both in an adequate education and in the maintenance of a stable family and cultural community; 2) the parents’ interest in controlling the upbringing of their children and in protecting their right to the free exercise of religion; 3) the community’s interest in preserving its identity; 4) and, the State’s interest, on the one hand, in educating its children in order to maintain an informed citizenry capable of participating in the economic and political spheres, and on the other hand, in the maintenance of diversity.While each of these interests appears significant and relevant to the enforcement of an educational policy, I will challenge the traditional way of addressing this problem as a balancing of these interests. Instead, I argue that the interests of children should be given primacy, and only after these interests have been addressed can the interests of others be given weight in determining and enforcing an educational policy.

ABSTRACTThe paper examines the suitability of the stable family of distributions with the Maturity Guarantees Working Party's stochastic investment model (Ford et al, 1980). It then examines the effect of replacing the Gaussian assumption made by the working party with a more general stable distribution. It also explains how the appropriate stable distribution can be fitted.

Previous studies have indicated that older men often experience disconnection from the community after retirement. Social activities have been shown to be effective in preventing social isolation among older urban men. Nevertheless, it has been reported that they often do not participate in community social activities and tend to be reluctant to do so. We explored the values and meanings of social activities for retired older men living in an urban area of Japan to understand support using social activities that are more suitable for them. Semi-structured interviews were conducted with 15 older men (aged 68–80 years; M = 74.6 ± 3.79 years) about their interactions with family and non-family members, and their participation in various community social activities. The grounded theory approach was used for the analysis. As a result, the following five categories were derived as the values that participants place on the social activities that they engage in: “health as a resource and reward for social activities,” “feeling I am still useful,” “feeling that something is my responsibility,” “feeling of time well spent,” and “finding interest through interactions.” In addition, the following three categories were extracted as meanings of social activities: “fulfilling social life,” “maintaining stable family relationships,” and “maintaining safety and peace in the community.” When considering the social activities that older urban retired men are interested in and likely to participate in, these five values can be considered indicators. In contrast, to maintain stable family relationships and safety and peace in the community, participants sometimes used strategies to stop or abandon social activities. Therefore, in situations where a peaceful life within a family or neighborhood is threatened, it may be useful to help set aside sufficient time and allow for psychological leeway in advance to incorporate social activities into their lives.

SummaryBeing happy is associated not only with better health, higher earnings and a longer life, but also with a stable family upbringing, stable financial situation, employment, good health, freedom and personal values. Psychiatrists may increase their patients' happiness by promoting effective, evidence-based mental healthcare. Individuals may enhance their own happiness by optimising physical and mental health; recognising the importance of personal values and happy communities; and optimising their financial situation. Government may boost citizens' happiness by deepening democracy; providing effective healthcare; supporting evidence-based well-being initiatives in communities; and then leaving citizens to seek out personal happiness in their own way.
