Does acculturation predict interpersonal adjustment? It depends on who you talk to     

Andrew G. Ryder  Lynn E. Alden  Delroy L. Paulhus  Jessica Dere 《Int J Intercult Relat》2013

Much acculturation research has investigated links with depression or with general psychological adjustment. Social adjustment, although critical to the acculturation process, has been relatively neglected. The association between acculturation and interpersonal problems was assessed in two samples of Chinese-Canadian university students using the Vancouver Index of Acculturation (VIA) and the circumplex version of the Inventory of Interpersonal Problems (IIP-C). Sample 1 participants (N = 185) completed the standard IIP-C, yielding a single effect: Mainstream acculturation predicted fewer problems with nonassertiveness. Sample 2 (N = 187) completed a short-form of the IIP-C twice – once referring specifically to problems they experienced in interacting with Chinese-Canadians and once referring specifically to problems interacting with Euro-Canadians. In this case, heritage acculturation predicted a pattern of interpersonal problems with Chinese-Canadian others and mainstream acculturation predicted a similar pattern with Euro-Canadian others. These results support the use of interpersonal adjustment measures in acculturation research, and suggest that such instruments should be modified so that questions refer directly to salient cultural groups in the respondent's social world.  相似文献   

干散货运价指数与钢材价格的联动关系     

张永锋  赵刚  陈继红 《上海海事大学学报》2016,37(2):53-58

为探究干散货运费市场的波动规律,以研究干散货运价指数与钢材价格联动为基础,探究大宗原材料的海运成本与产品价格之间的联动关系和联动机制.以2003—2013年波罗的海海岬型指数（Baltic Capesize Index,BCI）与国际钢材价格指数（由Commodity Research Unit研发,记为CRU指数）的周度数据作为基础,用ADF和Johansen检验法验证数据的平稳性与协整特征;在符合平稳性要求基础上,引入Granger因果检验方法,探索BCI与CRU指数之间的因果关系.通过GARCH模型,评估运输成本与产品价格之间的溢出效应及其相关性影响程度.最后,结合数据分析结果,构建大宗原材料的运输成本与原材料价格之间的联动机制.研究表明：钢材价格对铁矿石海运运费有非常重要且直接的影响,而铁矿石海运运费对钢材价格并无直接的影响;BCI与CRU指数存在显著的自相关,但是BCI更容易受到其他因素变化的干扰;BCI和CRU指数都具有显著的ARCH效应,且BCI波动本身对未来的影响是逐步衰弱的;CRU指数对BCI的影响较小且综合影响为正相关,而BCI对CRU指数的影响较大且综合影响为负相关.  相似文献   

CPI、PPI、PMI对经济发展影响的实证研究--基于SVAR模型的分析     

赵怡 《保定学院学报》2016,(4):41-45

随着社会主义市场经济和经济全球化进程的深入发展,市场竞争日益激烈,影响经济发展的因素也日渐繁多。这一变化固然给国家经济发展带来了更多的机遇,但也增加了经济增长预测的难度。由此,及时准确地把握市场经济走向,了解经济运行态势显得尤为重要。将价格指数CPI、PPI与采购经理指数PMI相结合,且用月度的工业增加值来代替季度的GDP指标,运用结构向量自回归（SVAR）模型来建立一个新的经济增长预测模型。实证结果表明,综合考虑了CPI、PPI、PMI三个指标的新模型,具有更好的拟合效果和预测效果。  相似文献

Computing semantic similarity based on novel models of semantic representation using Wikipedia     

Rong Qu  Yongyi Fang  Wen Bai  Yuncheng Jiang 《Information processing & management》2018,54(6):1002-1021

Computing Semantic Similarity (SS) between concepts is one of the most critical issues in many domains such as Natural Language Processing and Artificial Intelligence. Over the years, several SS measurement methods have been proposed by exploiting different knowledge resources. Wikipedia provides a large domain-independent encyclopedic repository and a semantic network for computing SS between concepts. Traditional feature-based measures rely on linear combinations of different properties with two main limitations, the insufficient information and the loss of semantic information. In this paper, we propose several hybrid SS measurement approaches by using the Information Content (IC) and features of concepts, which avoid the limitations introduced above. Considering integrating discrete properties into one component, we present two models of semantic representation, called CORM and CARM. Then, we compute SS based on these models and take the IC of categories as a supplement of SS measurement. The evaluation, based on several widely used benchmarks and a benchmark developed by ourselves, sustains the intuitions with respect to human judgments. In summary, our approaches are more efficient in determining SS between concepts and have a better human correlation than previous methods such as Word2Vec and NASARI.  相似文献   

Automated estimation of item difficulty for multiple-choice tests: An application of word embedding techniques     

Fu-Yuan Hsu  Hahn-Ming Lee  Tao-Hsing Chang  Yao-Ting Sung 《Information processing & management》2018,54(6):969-984

Pretesting is the most commonly used method for estimating test item difficulty because it provides highly accurate results that can be applied to assessment development activities. However, pretesting is inefficient, and it can lead to item exposure. Hence, an increasing number of studies have invested considerable effort in researching the automated estimation of item difficulty. Language proficiency tests constitute the majority of researched test topics, while comparatively less research has focused on content subjects. This paper introduces a novel method for the automated estimation of item difficulty for social studies tests. In this study, we explore the difficulty of multiple-choice items, which consist of the following item elements: a question and alternative options. We use learning materials to construct a semantic space using word embedding techniques and project an item's texts into the semantic space to obtain corresponding vectors. Semantic features are obtained by calculating the cosine similarity between the vectors of item elements. Subsequently, these semantic features are sent to a classifier for training and testing. Based on the output of the classifier, an estimation model is created and item difficulty is estimated. Our findings suggest that the semantic similarity between a stem and the options has the strongest impact on item difficulty. Furthermore, the results indicate that the proposed estimation method outperforms pretesting, and therefore, we expect that the proposed approach will complement and partially replace pretesting in future.  相似文献   

Family profiles of maltreated children in Singapore: A latent class analysis     

《Child abuse & neglect》2018

Children who enter the child protection system often have complex family problems and have experienced early adverse experiences. Using latent class analysis, this study aimed to identify family classes of child protection cases in Singapore, to ascertain the prevalence of these family classes, and to test the association of family class membership to subsequent recurrence of harm. A sample of 440 cases who entered the Child Protective Service in Singapore was analyzed based on eight familial factors on the household and caregiver levels. A four-class solution was found to demonstrate the best fit: (a) the large household group was intergenerational and majority lived with extended family members, (b) the harsh parenting group showed high levels of parenting problems and the caregiver justifying his abuse/neglect, (c) the high criminality group had high levels of caregiver substance abuse and caregiver arrest and incarceration history, and (d) the low disadvantage group rated low on all the familial factors. A Cox Regression revealed that in comparison to the low disadvantage group, the harsh parenting group was twice as likely to have recurrence of harm. There were also differences across family classes with regard to age at entry into child protection, gender composition and abuse types. The findings and practice implications are discussed.  相似文献   

Maltreatment in childhood and intimate partner violence: A latent class growth analysis in a South African pregnancy cohort     

《Child abuse & neglect》2018

Intimate partner violence (IPV) is a significant global problem, prevalent in low and middle-income countries (LMICs). IPV is particularly problematic during the perinatal and early postnatal period, where it is linked with negative maternal and child health outcomes. There has been little examination of profiles of IPV and early life adversity in LMIC contexts. We aimed to characterize longitudinal IPV and to investigate maternal maltreatment in childhood as a predictor of IPV exposure during pregnancy and postnatally in a low resource setting. This study was nested in the Drakenstein Child Health Study, a longitudinal birth cohort. Maternal IPV (emotional, physical and sexual) was measured at six timepoints from pregnancy to two years postpartum (n = 832); sociodemographic variables and maternal maltreatment in childhood were measured antenatally at 28–32 weeks’ gestation. Associations between maternal maltreatment in childhood and IPV latent class membership (to identify patterns of maternal IPV exposure) were estimated using multinomial and logistic regression. We observed high levels of maternal maltreatment during childhood (34%) and IPV during pregnancy (33%). In latent class analysis separating by IPV sub-type, two latent classes of no/low and moderate sexual IPV and three classes of low, moderate, and high emotional and physical IPV (separately) were detected. In combined latent class analysis, including all IPV sub-types together, a low, moderate and high exposure class emerged as well as a high antenatal/decreasing postnatal class. Moderate and high classes for all IPV sub-types and combined analysis showed stable intensity profiles. Maternal childhood sexual abuse, physical abuse and neglect, and emotional abuse predicted membership in high IPV classes, across all domains of IPV (aORs between 1.99 and 5.86). Maternal maltreatment in childhood was associated with increased probability of experiencing high or moderate intensity IPV during and around pregnancy; emotional neglect was associated with decreasing IPV class for combined model. Intervening early to disrupt this cycle of abuse is critical to two generations.  相似文献   

Exploring the applicability of the Semantic Web for discovering and navigating Australian Indigenous knowledge resources     

Aaron Corn  with Steven Wantarri Jampijinpa Patrick 《档案与原稿》2019,47(1):131-152

ABSTRACT

Semantic Web ontology files can be flexibly programmed to delineate metadata relationships in machine-readable formats to create relational pathways for discovering resources both on and off the Internet. There is a global community of Semantic Web developers and users across a broad multi-disciplinary range of interests who create and share extensible open-source ontologies. In this article, the author will explore the functionality of Semantic Web techniques for representing the ontologies of relatedness through kinship that typically underpin Australian Indigenous knowledge systems, and investigate their potentials for meeting persistent demands among leading Australian Indigenous collections creators and users to be able to search and discover their hereditary knowledge resources in ways that reflect and reinforce their enduring cultural values, ways of knowing and rights-management concerns.  相似文献
