What is A Philosophical Question?

There are many ways of understanding the nature of philosophical questions. One may consider their morphology, semantics, relevance, or scope. This article introduces a different approach, based on the kind of informational resources required to answer them. The result is a definition of philosophical questions as questions whose answers are in principle open to informed, rational, and honest disagreement, ultimate but not absolute, closed under further questioning, possibly constrained by empirical and logico‐mathematical resources, but requiring noetic resources to be answered. The article concludes with a discussion of some of the consequences of this definition for a conception of philosophy as the study (or “science”) of open questions, which uses conceptual design to analyse and answer them.     

超滤在小儿体外循环心脏手术中应用的临床决策

体外循环(CPB)技术的运用,使心脏直视手术的安全开展成为可能,但是体外循环可造成患者心肺功能的损伤,这种表现对心肺尚未发育成熟的婴幼儿的影响尤为严重。超滤已经成为低体重和危重患儿体外循环心脏手术中的一项重要技术,对患儿术后心肺功能的改善起着重要的作用。不同的超滤技术有各自的优缺点,需要我们在临床工作中合理应用。     

On the distinction between open and closed economies.

Open and closed economies have been assumed to produce opposite relations between responding and the programmed density of reward (the amount of reward divided by its cost). Experimental procedures that are treated as open economies typically dissociate responding and total reward by providing supplemental income outside the experimental session; procedures construed as closed economies do not. In an open economy responding is assumed to be directly related to reward density, whereas in a closed economy responding is assumed to be inversely related to reward density. In contrast to this predicted correlation between response-reward relations and type of economy, behavior regulation theory predicts both direct and inverse relations in both open and closed economies. Specifically, responding should be a bitonic function of reward density regardless of the type of economy and is dependent only on the ratio of the schedule terms rather than on their absolute size. These predictions were tested by four experiments in which pigeons' key pecking produced food on fixed-ratio and variable-interval schedules over a range of reward magnitudes and under several open- and closed-economy procedures. The results better supported the behavior regulation view by showing a general bitonic function between key pecking and food density in all conditions. In most cases, the absolute size of the schedule requirement and the magnitude of reward had no effect; equal ratios of these terms produced approximately equal responding.     

Relationship of social rank in mice to growth,endurance, and fertility

The influence of the social rank of male mice, determined by the outcome of fights, was assessed on their growth, treadmill performance, open-field behavior, and morphometric traits. Fertility of mated females was also investigated. Special attention was paid to the relationship between the male's social rank and body weight. Winners of fights were heavier than losers; their latencies were shorter, and they showed more locomotor activity in an open field test. Winners also had higher absolute testicular and epididymal weights. These males had a positive influence on the reproductive fitness of the females with which they were mated.     

Open live supervision in family therapy

This article reviews changes in models of supervision, resulting from technological developments and reflecting a variety of theoretical approaches. The focus is on open live supervision, conducted in the presence of the family. The supervisor and a therapeutic team join the therapist and the family, creating a complex supra-system that opens up several options for therapeutic intervention. Sessions are videotaped, and therapists use recordings for additional supervision and independent study. Therapists may also show recordings to the family as part of the therapeutic process. The advantages and disadvantages of the model are considered, and examples of some of the therapeutic options are described.This model was developed in the course of the author's work teaching and supervising students at the Counseling Department of the School of Education at the Hebrew University of Jerusalem, and supervising a multi-disciplinary team including physicians, psychologists, and social workers engaged in family therapy at the Municipal Psychological Services for Schools in Jerusalem. A shorter version of this article appeared in Hebrew inSihot 5 1991. Appreciation is expressed to Batya Stein for translating the final version of this article from Hebrew.

桡骨小头粉碎性骨折的两种治疗方法比较分析

分析比较切开复位内固定和人工桡骨小头置换方法治疗桡骨小头粉碎性骨折（MasonⅢ型）的临床疗效。回顾分析2012年10月～2014年3月收治的24例桡骨小头粉碎性骨折（MasonⅢ型）的临床资料,其中切开复位内固定治疗17例;桡骨小头置换7例,平均随访12个月（6个月～18个月）。根据Broberg Morrey评分系统以及术后影像进行评价比较,同时比较两组住院天数以及费用。结果评价比较显示两者疗效均佳,术后两者活动度和功能评分相近,两组住院天数相近,内固定组费用更低。桡骨小头粉碎性骨折须尽早进行解剖复住功能重建,切开复位内固定和桡骨小头置换疗效相当。
