Motivated by the need to analyze the National Longitudinal Surveys data, we propose a new semiparametric longitudinal mean‐covariance model in which the effects on dependent variable of some explanatory variables are linear and others are non‐linear, while the within‐subject correlations are modelled by a non‐stationary autoregressive error structure. We develop an estimation machinery based on least squares technique by approximating non‐parametric functions via B‐spline expansions and establish the asymptotic normality of parametric estimators as well as the rate of convergence for the non‐parametric estimators. We further advocate a new model selection strategy in the varying‐coefficient model framework, for distinguishing whether a component is significant and subsequently whether it is linear or non‐linear. Besides, the proposed method can also be employed for identifying the true order of lagged terms consistently. Monte Carlo studies are conducted to examine the finite sample performance of our approach, and an application of real data is also illustrated.  相似文献

As part of a comprehensive environmental health strategic planning project initiated by the government of Abu Dhabi, we assessed potential dietary exposure in the United Arab Emirates (UAE) to methylmercury (in seafood) and pesticides (in fruits and vegetables) above international guideline levels. We present results for the UAE population by age, gender, and body mass index. Our results show very low daily risks of exposure to pesticides in fruits and vegetables at levels exceeding WHO guidelines even under the conservative assumption that no pesticides are removed during washing and food preparation. Thus, exposure to pesticides on fruits and vegetables does not appear to be a major public health concern in the UAE. The chances of exposure to methylmercury in seafood are much higher; our model estimates a mean 1 in 5 daily risk of exceeding the FAO/WHO provisional tolerable weekly intake. However, great caution should be used in interpreting these results, as we analyzed only the risks and not the substantial benefits of fish consumption. In fact, previous studies have demonstrated that exposure to the n‐3 polyunsaturated fatty acids in fish can increase IQ in developing children, and it can substantially decrease the risk in adults of coronary heart disease and stroke. Further research is warranted to compare the risk of Me‐Hg exposure from fish to the nutritional benefits of fish consumption in the UAE and to determine appropriate methods to communicate risk and benefit information to the UAE population.  相似文献

Person‐centred approaches place individuals with a disability at the centre of decision making, with their carers and family invited to be partners in the process. Rather than being required to fit within existing service programs, person‐centred approaches enable individuals to choose the support options that best meet their needs. In order to facilitate this, person‐centred approaches will be accompanied by the introduction of individualised funding. This means the individual will be provided with funding to purchase services of their choosing. Given these significant changes occurring in the disability sector, Carers NSW surveyed informal carers of people with a disability to identify what they knew about person‐centred approaches and how they felt about their introduction. Survey results indicate that there is a need to increase the capacity and willingness of carers significantly in order to engage with person‐centred approaches and individualised funding. Carers require targeted and comprehensive information about these concepts in order to understand fully the changes occurring within the disability sector. These findings also indicate specific areas that need to be addressed in order to increase carers' awareness of these concepts and also to address existing negativity and confusion.  相似文献

The purpose of this paper is to describe and illustrate with case examples a brief intervention termed Radical Exposure Tapping (RET). RET can be integrated with family therapy to address stuck points where the therapy is hindered by a family member's affective block, an intense and unchangeable emotional reactivity to a specific trigger. RET draws from the methodology of Eye Movement Desensitization and Reprocessing (EMDR) and combines it with the tapping sequence of the Emotional Freedom Technique (EFT) to produce an intervention that is more flexible than EMDR, provides greater rigor than using the EFT technique alone and can be effective in a single session within the context of family therapy. The paper puts this work into context by first over viewing definitions of trauma and Post‐Traumatic Stress Disorder, arguing that family members' emotional reactivity may be a symptom of PTSD even when they would not qualify for the diagnosis because they had not experienced a life threatening event.  相似文献

堪称当代日本中国学代表的村田雄二郎出版了大量涉华著述,从社会学、政治学等角度对鸦片战争至清末的清廷国家观的变迁做了阐释,由"天朝定制"、"家国同构"、"地方自治与中央集权"等论点构成了其理论架构,与我国史学界的相关研究相比,角度新颖,确有可借鉴之处。另一方面,日本学者的立场也不乏偏颇之处,作者在对其批驳的基础上提出了自己的观点。  相似文献

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs.  相似文献

Advocating acceptance, committed action, and value-guided behavior over experiential avoidance, Acceptance and Commitment Therapy (ACT) may aid lesbian, gay, bisexual and transgender (LGBT) clients affected by hetero/homonormative social pressure. By conceptualizing LGBT paradigms of internal/external control/responsibility (IC-IR; EC-IR; IC-ER; EC-IR), ACT may be adapted to a myriad of multicultural worldviews. This article presents locus of acceptance as the attributed worth of internal/external cues perceived necessary by the client to achieve self-acceptance. Recognizing visibility and isolation as recurrent LGBT issues, locus of acceptances balances identity as individual (internal acceptance) with identity as community (external acceptance).  相似文献

Work values might be proximal predictors of individuals' late‐career intentions because they serve as guiding principles for the selection, evaluation, and justification of vocational behavior. The purpose of this study was to examine the relationship between work values and post‐retirement work intentions. The authors investigated individual work values within the structure of 4 higher order values elaborated on by Schwartz et al. ( 2012 ). Relationships between work values and 4 types of post‐retirement work intentions were examined. Data from 1,071 employees of a German logistics company were used to test the hypotheses. The results of a structural equation model indicated that work values were differentially related to the 4 types of post‐retirement work intentions. The identified work value–work type combinations add to the literature on post‐retirement work. Practice implications for promoting positive individual and organizational outcomes are drawn from the results.  相似文献
