In the 1980s and early 1990s, the normativity of meaning was thought to be more-or-less ‘incontestable.’ But in the last 25 years, many philosophers of mind and language have contested it in several seemingly different ways. This, however, is somewhat illusory. There is an unappreciated commonality among most anti-normativist arguments, and this commonality, I argue, poses a problem for anti-normativism. The result, however, is not a wholesale rejection of anti-normativism. Rather, an insight from the anti-normativist position can be harnessed to reveal an unappreciated position in the normativity of meaning debate.  相似文献

Abstract

This study aimed to investigate the effect of problem-solving based family therapy on the emotional intimacy and marital quality of cultural couples in Tabriz. The research method was quasi-experimental by designing the pretest and post-test with the experimental group. The statistical population of this research consisted of all cultural couples with marital problems referring to counseling centers of Tabriz Education in 2019. The research sample based on The Cochran formula consisted of 32 couples that were selected by purposeful sampling and were randomly assigned into two experimental and control groups. The experimental group was exposed to 10 sessions of problem-solving based family therapy and the control group received no interventions. The research tool was the Marital Quality Index and the Intimacy Questionnaire, which was completed by both groups at the beginning and end of the intervention. The collected data were analyzed using SPSS software and inferential statistics of covariance analysis were also investigated. The results of covariance analysis showed that problem-solving based family therapy had a significant impact on the emotional intimacy and marital quality of cultural couples. Therefore, problem-solving based family therapy can be used as a treatment in couples with marital problems.  相似文献

A comprehensive analysis of clustering techniques is presented in this paper through their application to data on meteorological conditions. Six partitional and hierarchical clustering techniques (k-means, k-medoids, SOM k-means, Agglomerative Hierarchical Clustering, and Clustering based on Gaussian Mixture Models) with different distance criteria, together with some clustering evaluation measures (Calinski–Harabasz, Davies–Bouldin, Gap and Silhouette criterion clustering evaluation object), present various analyses of the main climatic zones in Spain. Real-life data sets, recorded by AEMET (Spanish Meteorological Agency) at four of its weather stations, are analyzed in order to characterize the actual weather conditions at each location. The clustering techniques process the data on some of the main daily meteorological variables collected at these stations over six years between 2004 and 2010.  相似文献

Despite its importance for well-being, surprisingly little is known about what determines how couples feel after a conflict. Using the peak-end rule, we examined whether partners’ post-conflict affect was mainly predicted by their most aversive or pleasant emotional experience (peaks) during the conflict, or by the emotional tone at the end of the interaction. One hundred and one couples engaged in a conflict interaction and afterwards evaluated their momentary affect during the interaction. Post-conflict affect (in terms of positive and negative feelings, and perceived partner responsiveness) was assessed immediately after the conflict, after a subsequent positive discussion, and upon returning to daily life (here, rumination about the relationship was assessed as well). Our results showed that the negative and positive peaks, but not the end emotion, predicted immediate and partly extended post-conflict affect in individuals. This finding has clinical implications for the mediation of couple conflict.  相似文献

Roads in developing countries carry mixed traffic with wide variations in static and dynamic characteristics of vehicles. The traffic flow is also generally devoid of lane discipline, with vehicles occupying any available road space ahead. In such a regime of traffic flow, the phenomena of merging of vehicles at intersections of two roads is complex, warranting further study. The merging maneuvers at T-intersections under congested traffic conditions were studied microscopically through video-recording. In congested situations, the merging vehicle attempts a complex merging maneuver to enter the main traffic stream. Two unique merging processes are commonly observed in mixed traffic: group and vehicle cover merging (these are generally not observed in countries such as US). The author is using these words first time in this study. These reflect the different types of driver behavior – merging in groups, and by taking cover of another vehicle. Probabilistic models for group and vehicle cover merging are developed that capture this unique merging behavior. Comprehensive microscopic data collection and extraction were carried out to study the merging process at T-intersection under congested conditions. Merging models were then estimated using maximum likelihood method with disaggregate data that was collected for a case study T-intersection in Chennai city, India. Such models can find applications in simulation of highly congested traffic flow in a realistic manner under mixed traffic conditions. They can also give insights on devising better traffic control measures at such intersections.  相似文献

The standard error (SE) stopping rule, which terminates a computer adaptive test (CAT) when the SE is less than a threshold, is effective when there are informative questions for all trait levels. However, in domains such as patient-reported outcomes, the items in a bank might all target one end of the trait continuum (e.g., negative symptoms), and the bank may lack depth for many individuals. In such cases, the predicted standard error reduction (PSER) stopping rule will stop the CAT even if the SE threshold has not been reached and can avoid administering excessive questions that provide little additional information. By tuning the parameters of the PSER algorithm, a practitioner can specify a desired tradeoff between accuracy and efficiency. Using simulated data for the Patient-Reported Outcomes Measurement Information System Anxiety and Physical Function banks, we demonstrate that these parameters can substantially impact CAT performance. When the parameters were optimally tuned, the PSER stopping rule was found to outperform the SE stopping rule overall, particularly for individuals not targeted by the bank, and presented roughly the same number of items across the trait continuum. Therefore, the PSER stopping rule provides an effective method for balancing the precision and efficiency of a CAT.  相似文献

This study examined the cost of substance use disorders treatment in a large healthcare organization. A survival analysis demonstrated that family therapy utilised the least number of sessions (M = 2.41) when treating substance use disorders followed by individual therapy (M = 3.38) and mixed therapy (M = 6.40). Family therapy was the least costly of the three types, at $124.55 per episode of care for a client, with individual therapy costing $170.22 and mixed therapy $319.55. The ratio of family therapists utilising family therapy was more than three to one compared to other licensed professionals. The percentages of clients coming back for more than one episode of care are fewest for family therapy (8.9%) followed by mixed therapy (9.5%) and individual therapy (12.0%).  相似文献

Why should I take care of my aging parents? How far will morality require me to sacrifice for this cause? I will study these questions from the perspectives of Confucianism and rule‐consequentialism. Confucians believe that the continuity of families and the interactions between members of different generations can enhance the integrity of society in the long run. However, since Confucianism may impose extreme demands on its followers, this theory may be problematic. In this paper, I argue that despite its demands, the Confucian doctrines are defensible and are worth upholding. To explain my view, I draw upon rule‐consequentialism and explain how the rule‐consequentialist analysis complements and enhances the Confucian claims. I believe that the consequentialist conception of Confucianism can provide a useful resource for responding to the moral challenge of population aging in the current state of the world.  相似文献
