While more studies are exploring the ways in which gender structures the family experiences of American‐born children of immigrants, there is less attention to how gender shapes later views on ethnicity and culture. Based on interviews with Korean, Chinese, and Taiwanese Americans in the New York–New Jersey metropolitan area, this article examines the different ways second‐generation children learn, interpret, and pass on the cultural values and family traditions in their adulthood. Because their family roles center on their roles as leaders and carriers of the family name through male heirs, sons—especially oldest sons—can fulfill their filial obligations through relatively orthodox and nonengaging cultural practices that although restrictive, do not threaten their personal goals and privileged status. However, daughters must negotiate more emotionally burdensome expectations and responsibilities by preserving family honor, acting as family caretakers, and juggling multiple responsibilities; thus, they tend to re‐create more subtle, self‐empowering, and emotionally engaging ways of interpreting and preserving their parents’ expectations on family culture. I argue that the gendered ways daughters and sons are taught to practice cultural values and protect family honor has significant bearing on their later views on ethnicity and culture but in complex ways that transcend the generational divide.  相似文献

Due to Godambe (1985 Godambe, V.P. (1985). The foundation of finite sample estimation in stochastic processes. Biometrika 72:419428.[Crossref], [Web of Science ®] [Google Scholar]), one can obtain the Godambe optimum estimating functions (EFs) each of which is optimum (in the sense of maximizing the Godambe information) within a linear class of EFs. Quasi-likelihood scores can be viewed as special cases of the Godambe optimum EFs (see, for instance, Hwang and Basawa, 2011 Hwang, S.Y., Basawa, I.V. (2011). Godambe estimating functions and asymptotic optimal inference. Stat. Probab. Lett. 81:11211127.[Crossref], [Web of Science ®] [Google Scholar]). The paper concerns conditionally heteroscedastic time series with unknown likelihood. Power transformations are introduced in innovations to construct a class of Godambe optimum EFs. A “best” power transformation for Godambe innovation is then obtained via maximizing the “profile” Godambe information. To illustrate, the KOrea Stock Prices Index is analyzed for which absolute value transformation and square transformation are recommended according to the ARCH(1) and GARCH(1,1) models, respectively.  相似文献

城乡迁移与精神健康:基于上海的实证研究   总被引:6,自引:0,他引:6  
改革开放以来,中国见证了规模甚巨的城乡迁移运动,社会学界对这一现象进行了广泛的研究,但对进入城市的移民的精神健康问题则少有涉及。本研究基于对上海城乡迁移群体的多阶段抽样调查以了解这一群体的精神健康状况。问卷的分析结果显示,25%的男性和6%的女性精神健康状态不好。进一步的路径分析显示,移民压力、社会支持和迁移意义以不同的路径影响精神健康。论文建议政府和社会各界要充分回应移民群体的精神健康需求。  相似文献

Summary  In this paper a basic model for analyzing the inventory placement problem in a supply chain is developed. The problem will be studied for a capacitated, multi-stage supply chain facing a continuous, stochastic demand for a single period for a single product — a specialty item with a very short selling season. The objective is to maximize the probability of achieving a set profit level. We prove that finding an optimal stock investment at the stages entails solving a mixed binary integer linear program. We characterize properties of the stock investment, examine two interesting cases where the stock investments have a simple structure, and develop a branch and bound approach for solving the more general case.
Zusammenfassung  In diesem Beitrag wird ein Grundmodell entwickelt, um das Problem der Lagerplatzierung in einer Lieferkette analysieren zu k?nnen. Das Problem wird für eine kapazitierte mehrstufige Lieferkette untersucht, wobei unterstellt wird, dass es um die Nachfrage nach einem einzigen Produkt für eine einzige Periode (einen Sonderartikel mit sehr kurzer Verkaufszeit) geht und diese Nachfrage stetig und stochastisch ist. Unter diesen Bedingungen soll die Wahrscheinlichkeit maximiert werden, ein vorgegebenes Gewinnniveau zu erreichen. Die Suche nach der optimalen Vorratsinvestition auf den Stufen der Lieferkette führt zur Formulierung eines gemischten ganzzahligen linearen Programmierungsproblems mit Bin?rvariablen. Die Eigenschaften der Bevorratungsinvestition werden charakterisiert, zwei interessante F?lle mit einer einfachen Struktur der Bevorratungsinvestition untersucht und ein Branch-and-Bound-Ansatz zur L?sung eines allgemeineren Problemfalls entwickelt.

Summary The co-worker approach offers workers additional armamentarium in working with families. Such advantages may never become manifest unless the workers both recognize possible limitations inherent in team endeavor and develop and even maximize the use of the co-worker relationship.The impact of the co-worker approach, as compared with other approaches, offers both personal and professional advantages. Personally, the worker engages in a continuing educational, self-awareness, and self-enhancing activity that contributes to his growth as a professional and as a person. The joy of relationships, mutual and reciprocal, is a part of this personal enhancement. Professionally, the promotion of therapy through examination and testing of new knowledge and skills based upon another professional's confirmation enhances the professional aspects of therapy. The use of co-workers further develops new styles of working with and in family constellations.  相似文献

Two conceptual models are proposed in this article—one for work discrimination and the other for discrimination coping strategies pertaining to lesbian, gay, and bisexual workers. The work discrimination model includes 3 dimensions (formal vs. informal, potential vs. encountered, and perceived vs. real). The coping strategies model outlines methods that deal with potential and encountered discriminations. It includes vocational choice and work adjustment strategies; the latter are further categorized under identity management or discrimination management strategies.  相似文献

The use of ambulatory assessment (AA) and related methods (experience sampling, ecological momentary assessment) has greatly increased within the field of adolescent psychology. In this guide, we describe important practices for conducting AA studies in adolescent samples. To better understand how researchers have been implementing AA study designs, we present a review of 23 AA studies that were conducted in adolescent samples from 2017. Results suggest that there is heterogeneity in how AA studies in youth are conducted and reported. Based on these insights, we provide recommendations with regard to participant recruitment, sampling scheme, item selection, power analysis, and software choice. Further, we provide a checklist for reporting on AA studies in adolescent samples that can be used as a guideline for future studies.  相似文献

We consider a make‐to‐stock, finite‐capacity production system with setup cost and delay‐sensitive customers. To balance the setup and inventory related costs, the production manager adopts a two‐critical‐number control policy, where the production starts when the number of waiting customers reaches a certain level and shuts down when a certain quantity of inventory has accumulated. Once the production is set up, the unit production time follows an exponential distribution. Potential customers arrive according to a Poisson process. Customers are strategic, i.e., they make decisions on whether to stay for the product or to leave without purchase based on their utility values, which depend on the production manager's control decisions. We formulate the problem as a Stackelberg game between the production manager and the customers, where the former is the game leader. We first derive the equilibrium customer purchasing strategy and system performance. We then formulate the expected cost rate function for the production system and present a search algorithm for obtaining the optimal values of the two control variables. We further analyze the characteristics of the optimal solution numerically and compare them with the situation where the customers are non‐strategic.  相似文献
