归谬法构成的理论探索

归谬法是论战性一类文体中运用得最多的一种推理方法,其构成具有逻辑基础,其语义类型包括理性义、情感义两种;归谬法的语用功能是证明,语用策略是避免正确评价,语用效果是无理而妙;联想是归谬法构成的主要心理基础。     

Caregiver Support Groups: Finding Common Ground

SUMMARY

Members of caregiver support groups for the elderly have much in common but also bring to the group different experiences and attitudes. This article explores how group workers knowledgeable about significant caregiver differences and their effects on the group can enrich the group experience for all members. The four caregiver issues examined are: (1) past history between the caregiver and care recipient, (2) ability of caregiver to privately pay for home care, (3) views on long-term care placement in a nursing home, and (4) stage of disease or level of care needed by care recipient. Essential beliefs regarding the value of differences described by Northen and Kurland provide a framework for the group worker.

也谈“现代性的三次浪潮”

本文比较了列奥·斯特劳斯与雅斯贝尔斯关于现代性问题的不同的解读角度,意在揭示现代性仍是我们今天不得不面对的极其重大的理论现实问题,其中涉及世俗化、功利化中的“应当”与“存在”、“理想”与“实际”、“传统”与“变革”以及价值相对主义、虚无主义等方面的问题;而在这些问题后面,还必须重新审视有关历史进步、社会平等、平民革命等“习以为常”了的观念。全部问题似乎可以归结为:无论西方现代性的道路多么曲折,也无论近代以来中国式的现代性特征多么异乎寻常,我们能否用现代性这个概念来说明问题之所在,并把现代性的追求视为一种无法逃脱的“宿命”     

Salmonella Prevalence Alone Is Not a Good Indicator of Poultry Food Safety

Salmonella is a leading cause of foodborne illness (i.e., salmonellosis) outbreaks, which on occasion are attributed to ground turkey. The poultry industry uses Salmonella prevalence as an indicator of food safety. However, Salmonella prevalence is only one of several factors that determine risk of salmonellosis. Consequently, a model for predicting risk of salmonellosis from individual lots of ground turkey as a function of Salmonella prevalence and other risk factors was developed. Data for Salmonella contamination (prevalence, number, and serotype) of ground turkey were collected at meal preparation. Scenario analysis was used to evaluate effects of model variables on risk of salmonellosis. Epidemiological data were used to simulate Salmonella serotype virulence in a dose‐response model that was based on human outbreak and feeding trial data. Salmonella prevalence was 26% (n = 100) per 25 g of ground turkey, whereas Salmonella number ranged from 0 to 1.603 with a median of 0.185 log per 25 g. Risk of salmonellosis (total arbitrary units (AU) per lot) was affected (p ≤ 0.05) by Salmonella prevalence, number, and virulence, by incidence and extent of undercooking, and by food consumption behavior and host resistance but was not (p > 0.05) affected by serving size, serving size distribution, or total bacterial load of ground turkey when all other risk factors were held constant. When other risk factors were not held constant, Salmonella prevalence was not correlated (r = ?0.39; p = 0.21) with risk of salmonellosis. Thus, Salmonella prevalence alone was not a good indicator of poultry food safety because other factors were found to alter risk of salmonellosis. In conclusion, a more holistic approach to poultry food safety, such as the process risk model developed in the present study, is needed to better protect public health from foodborne pathogens like Salmonella.

Functional regression concurrent model with spatially correlated errors: application to rainfall ground validation

In this paper, we give an extension of the functional regression concurrent model to the case of spatially correlated errors. We propose estimating the spatial correlation structure by using functional geostatistics. The estimation of the regression parameters is carried out by feasible generalized least squares. This modeling approach is motivated by the problem of validating rainfall data retrieved from satellite sensors. In this sense, we use the methodology to study the relationship between satellite and ground rainfall time series recorded in 82 weather stations from Department of Valle del Cauca, Colombia. The model obtained allows predicting pentadal rainfall curves in many sites of the region of interest by using as input the satellite information. A residual analysis shows a good performance of the methodology proposed.     

SPECIAL ISSUE： DIALOGUE,INTERACTION AND NEW.DEVELOPMENTS IN PHILOSOPHY IN CONTEMPORARY CHINA - SPECIALIST FORUM ON CHINESE,WESTERN AND MARXIST PHILOSOPHIES：Contemporariness： a common field for dialogue between Chinese,Western and Marxist philosophies

如果说当代中国哲学的新开展意味着中国哲学的当代性展开,那么首要的问题就是理解何渭当代性。当代性不是一个历史学的概念,而是一个历史哲学的观念。当代性既不同于现代性,也不同于后现代性,而是在当下生活中的同时发生、同时在场。既然当代中国哲学是中国哲学的当代性展开,这就意味着当代中国哲学乃是在当下生活情境中发生、而且是与当代西方哲学和当代马克思主义哲学同时在场的。这就是三者之间的对话之所以可能的共同场域。
