Attribute Charts for Zero-Inflated Processes

The classical Shewhart c-chart and p-chart which are constructed based on the Poisson and binomial distributions are inappropriate in monitoring zero-inflated counts. They tend to underestimate the dispersion of zero-inflated counts and subsequently lead to higher false alarm rate in detecting out-of-control signals. Another drawback of these charts is that their 3-sigma control limits, evaluated based on the asymptotic normality assumption of the attribute counts, have a systematic negative bias in their coverage probability. We recommend that the zero-inflated models which account for the excess number of zeros should first be fitted to the zero-inflated Poisson and binomial counts. The Poisson parameter λ estimated from a zero-inflated Poisson model is then used to construct a one-sided c-chart with its upper control limit constructed based on the Jeffreys prior interval that provides good coverage probability for λ. Similarly, the binomial parameter p estimated from a zero-inflated binomial model is used to construct a one-sided np-chart with its upper control limit constructed based on the Jeffreys prior interval or Blyth–Still interval of the binomial proportion p. A simple two-of-two control rule is also recommended to improve further on the performance of these two proposed charts.     

Records Properties of Non Stationary Time Series

This article proposes an asymptotic expansion for the Studentized linear discriminant function using two-step monotone missing samples under multivariate normality. The asymptotic expansions related to discriminant function have been obtained for complete data under multivariate normality. The result derived by Anderson (1973 Anderson , T. W. ( 1973 ). An asymptotic expansion of the distribution of the Studentized classification statistic W . The Annals of Statistics 1 : 964 – 972 .[Crossref], [Web of Science ®] , [Google Scholar]) plays an important role in deciding the cut-off point that controls the probabilities of misclassification. This article provides an extension of the result derived by Anderson (1973 Anderson , T. W. ( 1973 ). An asymptotic expansion of the distribution of the Studentized classification statistic W . The Annals of Statistics 1 : 964 – 972 .[Crossref], [Web of Science ®] , [Google Scholar]) in the case of two-step monotone missing samples under multivariate normality. Finally, numerical evaluations by Monte Carlo simulations were also presented.     

A Detrended Range Unit Root (DRUR) Test

We extend the Range Unit Root test in two directions. First, we consider the process with time trend and prove that the modified standardized number of new records converges to a sum of two Rayleigh distributions. Second, more general structures of autocorrelated disturbances are also taken into account. Monte Carlo experiments show the good sample properties of this nonparametric unit root test.     

马来班顿体和土生华人班顿体比兴中的自然物象

对某些学者而言,马来班顿体也许是马来世界和马来灵魂的完美镜像。班顿体是一种口头文学,它扎根于许多不同的族群中,通过口头方式代代相传。本文的研究焦点是马来和马来西亚土生华人班顿体,其中有些文本直接录自马六甲和新加坡的口述者,分析的重点是马来班顿体首联中对自然的偏爱是如何在土生华人班顿体中得到强调的。此外,强调自然比兴的这种手法是马来班顿体和土生华人班顿体冲突后产生的“镜像效应”。这两种班顿体中反复出现的自然景象强调了当时与之紧密相关的日常生活,同时也形成了班顿体独特的审美性。     

Bourdieu,ethics and symbolic power

This article critically discusses Pierre Bourdieu's views on ethics and normative evaluations. Bourdieu acknowledged that people hold ethical stances, yet sought to show that these stances are – unconsciously – conducive to obtaining symbolic power and legitimizing hierarchy. The first part of the article looks at this argument and charts the shifts it went through particularly in the early 1990s. The second part discusses ontological and empirical critiques of the ethics as ideology argument and suggests the latter to be more salient, as Bourdieu proposed his argument as an empirical rather than as an ontological point. The reason why he nevertheless found the ethics as ideology explanation fitting to nearly all the cases he studied, as the third part argues, is not simply that reality ‘obliged’ him to do so, but his circular definition of symbolic capital as qualities that are worthy of esteem. This definition makes his argument of ethics as ideology unfalsifiable and impedes him from distinguishing between cases when legitimate power is the aim of ethics and between those when it is merely their side effect. The article concludes by suggesting ways in which Bourdieu's work can be fruitfully incorporated into the study of ethics once the tautology is resolved.     

Les Écossais en France: a modern diaspora?

This paper examines the contemporary Scottish diaspora living and working in France. It considers the makeup, origins, drivers and influences of the diaspora, as well as considering the attitudes and behaviour of the diaspora itself. Through face to face interviews the paper considers the identity held by individuals within the diaspora, organisations they are (or are not) involved with and how they interact with the host country. It also considers diaspora attitudes held towards the homeland, and towards contemporary socio-political events taking place within Scotland today. The paper discusses the modern nature of the diaspora, the strong sense of national identity it holds, and how the Scottish Government may not be connecting with this diaspora at all.     

Are LGBT Populations at a Higher Risk for Suicidal Behaviors in Australia? Research Findings and Implications

The aim of this article is to review the Australian literature about suicidality in minority sexual identity and/or behavior groups in order to determine the evidence base for their reported higher vulnerability to suicidal behaviors than heterosexual and non-transgendered individuals in the Australian context, as well as to identify the factors that are predictive of suicidal behaviors in these groups in Australia. A literature search for all available years (until the end of 2012) was conducted using the databases Scopus, Medline, and Proquest for articles published in English in peer-reviewed academic journals. All peer-reviewed publications that provided empirical evidence for prevalence and predictive factors of suicidal behaviors among LGBT individuals (or a subset thereof) in Australia were included. Reference lists were also scrutinized to identify “gray” literature for inclusion. The results revealed that there is only limited research from Australia. Nevertheless, although no population-based studies have been published, research indicates that sexual minorities are indeed at a higher risk for suicidal behaviors. In order to further the understanding of suicidal behaviors and potential prevention among LGBT groups in the Australia, further research is needed, particularly on fatal suicidal behaviors.

Migrant narratives as photo stories: on the properties of photography and the mediation of migrant voices

This article examines how the properties of photography might mediate voice, defined as the capacity to speak and to be heard speaking about one’s life and the social conditions in which one’s life is embedded. It focuses on the affordances that the image provides for migrant cultural minorities to articulate such a voice within the context of collaborative research. I look at the case of Shutter Stories, a collaborative photography exhibition featuring the photo stories of Indian and Korean migrants from Manila, The Philippines. Using participant observation data, I show that it was photography’s ability to be all at once indexical, iconic, and symbolic that became important in voice as ‘speaking’. It allowed migrants to tell rich, multimodal narratives about their lives, albeit with some key limitations. I also show that it was photography’s inability to fix meanings with finality that mattered in voice as ‘being heard’. Although the locals who visited the exhibition engaged with the photo stories in an overwhelmingly positive manner, they often did not completely grasp the migrants’ complex narratives. All these data indicate that collaborative photography exhibition projects should not just be about how migrants speak and are heard. They should also be about how migrants can listen, so that they can adjust what they say to how they are being heard. This is a valuable reminder that in conceptualising photography and migrant cultural minority voices, we also need to take into account the broader process of multicultural dialogue.     

‘For the sake of the family and future’: the linked lives of highly skilled Indian migrants

ABSTRACT

While in Western literature, migration is generally considered an individual or (nuclear) household phenomenon, Indian context adds the strong presence of parents and extended family to the constellation. This paper addresses how significant others shape the life course events and the migration trajectories of highly skilled Indian migrants to the Netherlands and UK. We employ a qualitative approach to the life course framework to highlight the linked lives that can alter the migration decisions. Our findings are drawn from 47 semi-structured biographic interviews. The results underscore how further migration decisions are often informed by the implications of the different life stages of the linked lives, the key elements being care-giving by and for the parents. Furthermore, we also illustrate how migration provides space for negotiating social norms and expectations: due to the geographical distance between migrants and their parents, the local (non-Indian) context plays a bigger role and thus the need for and timing of conformity with norms can be postponed. The understanding of family life in transnational settings will be enriched when individuals are embedded within the cultural background and linked lives are extended beyond the immediate nuclear family.
