To model an hypothesis of double monotone dependence between two ordinal categorical variables A and B usually a set of symmetric odds ratios defined on the joint probability function is subject to linear inequality constraints. Conversely in this paper two sets of asymmetric odds ratios defined, respectively, on the conditional distributions of A given B and on the conditional distributions of B given A are subject to linear inequality constraints. If the joint probabilities are parameterized by a saturated log-linear model, these constraints are nonlinear inequality constraints on the log-linear parameters. The problem here considered is a non-standard one both for the presence of nonlinear inequality constraints and for the fact that the number of these constraints is greater than the number of the parameters of the saturated log-linear model.This work has been supported by the COFIN 2002 project, references 2002133957_002, 2002133957_004.

To understand outcomes for Pacific peoples in New Zealand we need to further our psychological knowledge of the relationship between Pacific identity and wellbeing. We map the hierarchical organization of Pacific identity and wellbeing using a novel top-down factor analytic approach applied to the Pacific Identity and Wellbeing Scale (PIWBS; N = 586). Analyses indicated that Pacific identity experiences were organized within two broad dimensions reflecting Identity Engagement and Cultural Wellbeing. Critically, our analysis showed that Religious Centrality and Embeddedness emerged jointly from these dual broad domains. Religious identification provides a bridging link between identity and wellbeing for Pacific peoples. Identifying the relationships of Pacific identity and wellbeing factors, and how religious identification emerges jointly from these two broad domains, provides valuable information in how the Pacific self may be cognitively organized and may assist in future research directions in this area. We assert that this general statistical model provides broad conceptual insights into how Pacific peoples experience their identity and culture, and how this relates to various social indicators of health and wellbeing at a broad, theoretical level. In particular, we offer a conceptual analysis of possible insights from our hierarchical model of identity and wellbeing for understanding Pacific suicide in New Zealand. 相似文献

Established management practices – such as Six Sigma or business process re‐engineering, as well as more recent practices such as agile management processes, HR analytics and beyond budgeting – are viewed by practitioners as the basic tools of their trade. Yet they have been known to wax and wane in popularity, often quite unpredictably, with one technique following the other in wave‐like fashion. The scholarly observation of this phenomenon has given rise to the literature on fads and fashions in management studies, which – building on earlier work in allied disciplines – has sought to explain the transience, persistence, and overall trajectory of management practices. In this paper, we review and integrate the existing literature on management fads and fashions, taking stock of the sizable body of work that has accumulated over the past three decades and which has, to our knowledge, never been reviewed comprehensively before. At the same time, we also note that technological change – with the advent of social media and the ubiquity of Internet connectivity, for example – has radically transformed how practitioners seek, consume, and engage with new practices, as well as the way in which such practices are broadcast and diffuse. In our review, therefore, we try to make this well‐established body of literature current by explicitly discussing how well its central tenets and theoretical arguments have stood the test of time, and propose useful directions for moving forward. 相似文献

This article investigates the determinants of remittance behaviours among foreigners in Italy and intends to gain a better understanding of the temporal pattern of remittances. The analysis is based on data from the 2009 “Italian Statistics on Income and Living Conditions of Households with Foreigners”. The decisions on whether to remit and how much to remit are separately yet simultaneously estimated using a zero‐inflated beta regression model. The findings reveal that remittances are driven by a mix of altruistic and self‐interest motives that may persist for many years. Many covariates included in the model have a different effect on the propensity to remit and on the relative amount of remittances. We find some evidence that the average propensity to remit follows an M‐shaped trajectory over time. However, the model specification including only time and time squared proves that the inverted‐U shape trajectory, well‐established in the literature, still remains a better choice in terms of parsimoniousness and flexibility. Among those who remit, time since migration does not have any significant effect on the normalized amount remitted. 相似文献

International regulatory authorities view risk management as an essential production need for the development of innovative, somatic cell‐based therapies in regenerative medicine. The available risk management guidelines, however, provide little guidance on specific risk analysis approaches and procedures applicable in clinical cell therapy manufacturing. This raises a number of problems. Cell manufacturing is a poorly automated process, prone to operator‐introduced variations, and affected by heterogeneity of the processed organs/tissues and lot‐dependent variability of reagent (e.g., collagenase) efficiency. In this study, the principal challenges faced in a cell‐based product manufacturing context (i.e., high dependence on human intervention and absence of reference standards for acceptable risk levels) are identified and addressed, and a risk management model approach applicable to manufacturing of cells for clinical use is described for the first time. The use of the heuristic and pseudo‐quantitative failure mode and effect analysis/failure mode and critical effect analysis risk analysis technique associated with direct estimation of severity, occurrence, and detection is, in this specific context, as effective as, but more efficient than, the analytic hierarchy process. Moreover, a severity/occurrence matrix and Pareto analysis can be successfully adopted to identify priority failure modes on which to act to mitigate risks. The application of this approach to clinical cell therapy manufacturing in regenerative medicine is also discussed. 相似文献

In this work a new type of logits and odds ratios, which includes as special cases the continuation and the reverse-continuation
logits and odds ratios, are defined. We prove that these logits and odds ratios define a parameterization of the joint probabilities
of a two way contingency table. The problem of testing equality and inequality constraints on these logits and odds ratios
is examined with particular regard to two new hypotheses of monotone dependence.

In this article, we revisit the importance of the generalized jackknife in the construction of reliable semi-parametric estimates of some parameters of extreme or even rare events. The generalized jackknife statistic is applied to a minimum-variance reduced-bias estimator of a positive extreme value index—a primary parameter in statistics of extremes. A couple of refinements are proposed and a simulation study shows that these are able to achieve a lower mean square error. A real data illustration is also provided. 相似文献

This exploratory study investigates the meaning that adults attribute to the facial expressions of neonates and young infants using different types of scales, and tries to assess whether adult judgments get more precise as the infants get older. We videotaped longitudinally six infants' facial expressions in 5 everyday life situations at 3 days, 1 month, and 3 months old. Untrained adult decoders had to assess the activation and pleasure/displeasure levels signaled by the isolated videotaped facial expressions, recognize the stimulus situations, and attribute a verbal label to each expression. Our results showed that inter-decoder agreement was higher when the babies' facial expressions were considered as signals of activation or of pleasure/displeasure, and decreased significantly when the expressions had to be interpreted as signals of specific situations or when a verbal label had to be ascribed. The specificity and the accuracy of the answers, and inter-decoder agreement, were higher for the older infants. 相似文献
