自然与文化:悲观哲学经验

人存在于自然之中,但人不是一般意义上的自然之物,因为人拒绝接受肉体腐烂后思想的荒芜,于是,人开始对自身存在的价值进行深度思考,其结果是,人拒绝承认自己和动植物具有相同的属性,因为人既是自然之子,也是文化的产物。只有当人的精神发展从意识自己是种群的组成部分返回到意识自己作为个体存在的价值和意义之时,文化的作用才有可能发生。人类的发展伴随着野蛮的状态,也伴随着对命运一词的不断认识。人的伟大之处在于能够意识到死亡的不可避免,但同时在文化的帮助下去克服死亡的恐惧,最后让死亡成为有意义的文化事件。     

The Socioeconomic Basis of Farm Enterprise Diversification Decisions1

Abstract In contrast to earlier studies, recent research on socioeconomic and ecological factors affecting farm decision making suggests that, at the microlevel, farm size is inversely related to specialization and directly related to diversification decisions but empirical tests have been limited. Using a social behavioral, farming systems perspective, we examine factors affecting diversification and specialization decisions, including land tenure, off-farm work, and education (which are crucial to successful management) and environmental variation (which affects the decision to select appropriate enterprises). Data from a random sample of Kentucky farmers were used to test the model. Diversification, whether defined according to crops or commodities, is significantly related to farm size, human capital, and regional variation in land and soil types. The study clarifies the relationship between diversification and farm size issues and broadens understanding of farm diversification decisions. The findings indicate that increased farm size and better farm management reduce the rate of increase in farm specialization.     

Disposable dispositions: reflections upon the work of Iris Marion Young in relation to the social oppression of autistic people

This brief commentary piece looks to apply the theories of Iris Marion Young to the social position and oppression of autistic people, as previously theorised by Milton. The concepts of ‘Asymmetrical symmetry’ and the ‘Five faces of oppression’ are explored in this regard. The article concludes by arguing that autistic people, particularly those who have significant intellectual impairments, can be socially marginalised to the extent of occupying the social position of ‘non-human’ with the staggering consequences for social well-being that this implies.     

Modeling U‐Shaped Exposure‐Response Relationships for Agents that Demonstrate Toxicity Due to Both Excess and Deficiency

Essential elements such as copper and manganese may demonstrate U‐shaped exposure‐response relationships due to toxic responses occurring as a result of both excess and deficiency. Previous work on a copper toxicity database employed CatReg, a software program for categorical regression developed by the U.S. Environmental Protection Agency, to model copper excess and deficiency exposure‐response relationships separately. This analysis involved the use of a severity scoring system to place diverse toxic responses on a common severity scale, thereby allowing their inclusion in the same CatReg model. In this article, we present methods for simultaneously fitting excess and deficiency data in the form of a single U‐shaped exposure‐response curve, the minimum of which occurs at the exposure level that minimizes the probability of an adverse outcome due to either excess or deficiency (or both). We also present a closed‐form expression for the point at which the exposure‐response curves for excess and deficiency cross, corresponding to the exposure level at which the risk of an adverse outcome due to excess is equal to that for deficiency. The application of these methods is illustrated using the same copper toxicity database noted above. The use of these methods permits the analysis of all available exposure‐response data from multiple studies expressing multiple endpoints due to both excess and deficiency. The exposure level corresponding to the minimum of this U‐shaped curve, and the confidence limits around this exposure level, may be useful in establishing an acceptable range of exposures that minimize the overall risk associated with the agent of interest.     

Eco-Six Sigma: integration of environmental variables into the Six Sigma technique

The impressive results achieved by several companies through the Six Sigma technique have motivated other organisations to follow their footsteps in search for competitiveness. As noticed in the literature, most Six Sigma projects in manufacturing have aimed to obtain process enhancements, focusing mostly on optimising product cycle times with almost none taking into consideration environmental aspects as part of their developments. Furthermore, organisations have been worrying worldwide about environmental issues, seeking to foster their eco-efficiency. As a result, the main objective of this paper is to formally introduce the environmental considerations into the Six Sigma technique by proposing a procedure to incorporate environmental variables into the DMAIC process as a way to increase the eco-efficiency level of the firms. Based on the literature review, a conceptual procedure to incorporate environmental variables into the Six Sigma DMAIC technique is proposed. To verify its possible application to real-life situations an action research was developed and could verify that the traditional Six Sigma approach (dealing only with the manufacturing process variables) was capable of improving the eco-efficiency level of the process area under study by 11%. The consideration of the environmental variables as part of the DMAIC technique as per the proposed approach allowed an additional 20% gain, which demonstrates its adequacy to increase the eco-efficiency level of the manufacturing area under evaluation.     

On the ontological status of autism: the ‘double empathy problem’

In recent decades there has been much debate over the ontological status of autism and other neurological ‘disorders’, diagnosed by behavioural indicators, and theorised primarily within the field of cognitive neuroscience and psychological paradigms. Such cognitive-behavioural discourses abstain from acknowledging the universal issue of relationality and interaction in the formation of a contested and constantly reconstructed social reality, produced through the agency of its ‘actors’. The nature of these contested interactions will be explored in this current issues piece through the use of the term the ‘double empathy problem’, and how such a rendition produces a critique of autism being defined as a deficit in ‘theory of mind’, re-framing such issues as a question of reciprocity and mutuality. In keeping with other autistic self-advocates, this piece will refer to ‘autistic people’, and ‘those who identify as on the autism spectrum’, rather than ‘people with autism’.     

Realistic Empathy and Active Nonviolence Confront Political Reality

This article employs three concepts to integrate the prior articles in this issue: political reality, realistic empathy, and active nonviolence. People of wealth and power define political reality, making their interests coterminous with national interests. Episodic and structural violence are used to maintain political reality. The prior articles report on diverse means to counter political reality, mitigate the effects of violence and lay the groundwork for peacebuilding. Basic to those means are realistic empathy and active nonviolence.     

A New Formulation For The Multinomial Selection Problem

The two approaches to a multinomial ranking and selection problem (for selecting the t best cells out of k are combined to form a new apprach. In this new approach there is a preference zone (PZ) and an indifference zone (IZ), and the concept of a correct selection (CS) is defined differentlv in eac of these zones. Lower bounds for the probability of correct selection p(CS) are then guaranteed in each of these zones using a single experiment. The procedure on the ordered frequencies in the cells. The principle tool used to derive expressins for the p(CS). for the expected sample size EN, for the expected subsct size ES and for other probabilities. is the Dirichlet integral (Type 2) which was recent tabulated. These Dirichlet integrals are used to prove that the multiplicative slippage configuratin is leas favorable in the PZ and, for t = l, that the IZ. Numerical calculations are carried out for an illustrative example but extensive tables are not yet avalable
