金融市场间波动溢出效应研究——GC-MSV模型及其应用

在资本自由流动、信息充分的背景下,金融市场之间受相同宏观经济因素的影响,往往会表现出协同变化的特征,外汇市场和股票市场间波动溢出效应一直是经济金融界研究的热点。随机波动模型是随机微分方程的离散化表示形式,其通过一个不可观测的随机过程来描述金融时间序列的波动特征,更适合于金融领域的实际研究。本文引入GC-MSV模型对我国汇改后汇市与股市间的波动溢出效应进行研究。实证结果表明,整体上汇市与股市间存在负相关的动态价格溢出效应;在人民币持续升值阶段和持续震荡阶段均存在不对称的波动溢出效应,且随时间推移波动溢出效应有所减弱。     

Expanding the role of long-term care social workers: assessment and intervention related to urinary incontinence

Urinary incontinence (UI) is a common and stigmatizing problem faced by long-term care (LTC) residents. It is typically addressed by medical professionals, with social work rarely involved. The purpose of this article is to illustrate how social workers can address the psychosocial implications of UI while working with residents and their family members as part of an interdisciplinary team. Using a case example and the NASW objectives for LTC, recommendations on how the role of the LTC social workers can be expanded to better address both the needs of residents, families, and the larger LTC system are provided.     

False positives or hidden dimensions: What can monetary and multidimensional measurement tell us about child poverty in Vietnam?

Roelen K, Gassmann F, de Neubourg C. False positives or hidden dimensions: what can monetary and multidimensional measurement tell us about child poverty in Vietnam? A widely used division between poverty measures based on conceptual underpinnings and analytical outcomes is that of monetary versus multidimensional measures. Comparisons of the use and outcomes of the two methods have shown that they predominantly provide different pictures of poverty in terms of size, rank and group. This article contributes to the long‐standing and ongoing debate on poverty measurement by comparing the use of monetary and multidimensional poverty approaches, with a special focus on children in Vietnam and extending the empirical analysis beyond conventional methods. In addition to investigating whether poverty outcomes or groups of identified poor children differ when using the two different poverty measures, we also investigated the drivers underlying these differences. Findings confirm a considerable degree of mismatch: both poverty measures proved to be inadequate proxies for the other and factors underlying the identification by either one or both of the measures differed.     

Benchmarking and Monitoring International Warehouse Operations in Europe

We report on a cross‐sectional and longitudinal comparison of European distribution centers in the Netherlands. European distribution centers are responsible for the distribution of a manufacturer's (mostly Asian or American) products over customers in a large part of Europe, the Middle East, and Africa, often with strict service‐level agreements. In total, 65 physical warehouses, containing 140 European, Asian, and American European distribution center operations, in combination with different outsourcing relations (own‐account, dedicated outsourced, and public outsourced), were benchmarked in 2000 and monitored over the period 2000–2004. We conclude that both in 2000 and 2004, European warehouses are more efficient than Asian and American warehouses, and outsourced operations (particularly public warehouses) are more efficient than own‐account operations. Over the period 2000–2004, efficiency appears to have declined substantially; the most distinct differences are to be found among public outsourced warehouses and, because many European distribution center warehouse operations of European origin are run by public service providers, among European warehouses. This decline in efficiency also led to a decline in productivity, in spite of the fact that overall the available technology has improved. We conjecture potential causes for this decline.     

Clinical management of gender dysphoria in children and adolescents: the Dutch approach

The Dutch approach on clinical management of both prepubertal children under the age of 12 and adolescents starting at age 12 with gender dysphoria, starts with a thorough assessment of any vulnerable aspects of the youth's functioning or circumstances and, when necessary, appropriate intervention. In children with gender dysphoria only, the general recommendation is watchful waiting and carefully observing how gender dysphoria develops in the first stages of puberty. Gender dysphoric adolescents can be considered eligible for puberty suppression and subsequent cross-sex hormones when they reach the age of 16 years. Currently, withholding physical medical interventions in these cases seems more harmful to wellbeing in both adolescence and adulthood when compared to cases where physical medical interventions were provided.     

Indeterminate Responses to Attitudinal Questions About Intimate Partner Violence Against Women in Rural Bangladesh

Using data from 165 participants in a survey experiment in six Bangladeshi villages, we explored the levels and correlates of women??s indeterminate responses to a five-part attitudinal question on intimate partner violence (IPV) against women from the 2007 Bangladesh Demographic and Health Survey. Over 80?% had indeterminate responses to all five parts of the question. Indeterminate responses included silence or initial non-response (53?C58?%), misunderstanding the question (30?C37?%), and conditional opinions (7?C13?%). The percentages of women who justified IPV were lower when indeterminate responses were permitted (7?C12?%) than when they were not (37?C57?%). Older women (??26?years) with less schooling (??2 grades) whose husbands were older (??36?years), had less schooling (??8 grades), and were at least 7?years older than the respondent often had higher odds of giving indeterminate responses. Husbands?? attributes and spousal age gaps were most consistently associated with women??s indeterminate responses. Latent power, or fears of expressing transgressive views, may underlie women??s indeterminate responses to attitudinal questions about IPV against women. Recommendations for further research are discussed.     

The relevance of class in shaping authoritarian attitudes: A cross-national perspective

This study provides the first thorough and cross-national assessment of the concept of authoritarianism with regard to the distinction between the working and non-working classes. This pan-European study is the first to demonstrate that, because there are no substantial differences in interpretation between the working class and the non-working class, authoritarianism scores can be compared meaningfully across the two classes. We demonstrate that the working class is more strongly inclined to authoritarianism, as suggested by Lipset. Building further upon this assessment allows a clear picture of the mediating effects of some of Lipset's presumed drivers of this relationship. Although educational levels explain a major part of class differences in authoritarianism, income level, media use and psychological insecurity play a role as well, albeit to a lesser extent. In addition to examining the underlying processes at the individual level, country-level characteristics are studied. Results show that class and authoritarianism are more strongly related to each other in richer countries than they are in relatively poor countries.     

On a new test for autocorrelation in regression models under nonnormality

A new test for autocorrelation in a general regression model under departures from the assumption of normality is derived by applying a beta distribution and bootstrap approximation, Critical values of the test, can be computed for each given design matrix, irrespective of the form of the underlying error distribution, Monte Carlo simulations are conducted in order to illustrate the performance of the test. Among others, it. is found that the suggested test is more robust and far more powerful than existing nonparametric tests.     

A simple test for new better than used in expectation

We present a statistical procedure to test that a life distribution is exponential against the al ternative that it is continuous new better than used in expectation. The test is shown to be consistent and asymptotic relative efficiency resul ts are obtained against the competitor developed earlier by Hollander and Proschan [2], for certain families of alternatives.
