This study examined whether international terrorism could be differentiated into different behavioural themes related to the way of using force. The sample consisted of 217 international terrorist organisations that had perpetrated five or more terrorist incidents. A non‐metric multidimensional scaling analysis revealed that all of the terrorist incidents could be assigned to one of three themes reflecting different styles of the use of force: ‘attack as threat’, ‘attack as means’, and ‘attack as violence’. In the current sample, 189 of the terrorist organisations repeated one theme in more than 50% of their series of incidents, suggesting their preference for one of the three themes.

Population counts and longitude and latitude coordinates were estimated for the 50 largest cities in the United States by computational linguistic techniques and by human participants. The mathematical technique Latent Semantic Analysis applied to newspaper texts produced similarity ratings between the 50 cities that allowed for a multidimensional scaling (MDS) of these cities. MDS coordinates correlated with the actual longitude and latitude of these cities, showing that cities that are located together share similar semantic contexts. This finding was replicated using a first-order co-occurrence algorithm. The computational estimates of geographical location as well as population were akin to human estimates. These findings show that language encodes geographical information that language users in turn may use in their understanding of language and the world. 相似文献

We explored differences in the mental representation of facial identity between 8-year-olds and adults. The 8-year-olds and adults made similarity judgments of a homogeneous set of faces (individual hair cues removed) using an “odd-man-out” paradigm. Multidimensional scaling (MDS) analyses were performed to represent perceived similarity of faces in a multidimensional space. Five dimensions accounted optimally for the judgments of both children and adults, with similar local clustering of faces. However, the fit of the MDS solutions was better for adults, in part because children’s responses were more variable. More children relied predominantly on a single dimension, namely eye color, whereas adults appeared to use multiple dimensions for each judgment. The pattern of findings suggests that children’s mental representation of faces has a structure similar to that of adults but that children’s judgments are influenced less consistently by that overall structure. 相似文献

A new nonmetric multidimensional scaling method is devised to analyze three-way data concerning inter-stimulus similarities obtained from many subjects. It is assumed that subjects are classified into a small number of clusters and that the stimulus configuration is specific to each cluster. Under this assumption, the classification of subjects and the scaling used to derive the configurations for clusters are simultaneously performed using an alternating least-squares algorithm. The monotone regression of ordinal similarity data, the scaling of stimuli and the K -means clustering of subjects are iterated in the algorithm. The method is assessed using a simulation and its practical use is illustrated with the analysis of real data. Finally, some extensions are considered. 相似文献

药物不良反应社会成本控制最优化的经济学分析 总被引:1,自引:0,他引:1
药物不良反应(adverse drug reaction,ADR)是导致患者住院的常见原因并造成高额的社会成本。由于避免ADR的边际成本是递增的,因此从经济学的角度来看,ADR的发生率不是最小化而是最优化问题,是在成本与效益之间找到最优平衡的问题,本文对ADR发生率的最优平衡点和相关的制度作了探讨。 相似文献

This paper will illustrate the utilization of systemic family therapy services inside a hospital in a war-affected region of the Central African Republic. Through an international non-governmental organization (NGO), the author, a family therapist, provided counselling supervision and services to hospital staff and patients in an area of open conflict in the northern region of the country. In circumstances of chronic insecurity fuelled by both government and rebel forces, families displaced in this region are vulnerable to numerous health conditions and social problems. Family therapy techniques and ideas were used to work with individuals, couples and families presenting with health and social problems resulting from HIV-TB, infections, chronic malnutrition, acute poisoning and beliefs about sorcery. Case examples illustrate the systems consultation model used with the mental health team in order to expand and promote the sustainability of patient mental healthcare in this underserved region. 相似文献

He, L., Cong, F., Liu, Y. & Zhou, X. (2010). The pursuit of optimal distinctiveness and consumer preferences. Scandinavian Journal of Psychology, 51, 411–417. This article investigates the effect of optimal distinctiveness on consumer product consumption. The authors argue that consumers acquire and display material possessions to restore their optimal levels of distinctiveness. Results showed that placing consumers in a state of low distinctiveness increased desire to acquire distinctive products, whereas perceptions of high distinctiveness reduced desire to acquire such products. Consumers’ desire for distinctiveness‐related products held true for various consumer choices, including willingness to pay more for limited‐edition products and preference for unpopular gifts. This finding has implications for understanding consumer choice in expressing identity. 相似文献

该研究从年龄效应这一独特视角探讨了内隐序列学习的表征机制。结果表明:(1)内隐序列学习存在具体联结和抽象层级编码双重表征机制,且在该研究中以抽象编码为主;(2)老、青、幼三组被试的内隐序列学习无显著差异,间接支持了具体联结机制不起主要作用的结论。该研究的推论是:(1)内隐序列学习的表征是一个遵循“最优级编码”的动态过程;(2)该过程不涉及注意机制和短时记忆。 相似文献
