纪念福柯逝世20周年——欲望与快感

德勒兹区分了自己的“欲望”概念与福柯的“快感”概念,从而划清了他们的思想界线。就权力装置而论,福柯在《监视与惩罚》中指出,欲望装配与压抑使事物标准化也使我们遵守纪律：德勒兹则认为它们将事物译成电码且再度疆域化。德勒兹提出“快感何以激活一些反权力?福柯何以构思这个快感概念?”这两个问题,认为关键在于福柯赋予了力量关系、真理、快感以全新意义。福柯的基本观念是,权力装置与身体具有直接而正面的关系,德勒兹则指出,权力装置恰恰在一定程度上把组织强加到了身体上。     

Treatment of panic disorder with agoraphobia: randomized placebo-controlled trial of four psychosocial treatments combined with imipramine or placebo

Few randomized controlled trials have included panic disorder patients with moderate to severe agoraphobia. Therefore, this population was studied using pharmacotherapy as well as psychotherapy. At the time of the study, imipramine was widely used as a pharmacological treatment. Also, current practice guidelines for patients with panic disorder find selective serotonin reuptake inhibitors and tricyclic antidepressants roughly comparable in terms of efficacy. Therefore, the main objective of this study is to compare four psychosocial treatments-cognitive and graded in vivo exposure treatments, graded in vivo exposure, cognitive treatment, and supportive therapy-to evaluate the benefits of combining cognitive therapy with exposure in vivo. These treatments were combined with imipramine or placebo for a total of eight experimental conditions. Participants presented moderate to severe agoraphobia. The method involved a randomized, double-blind, placebo-controlled trial with 137 participants who completed a 14-session protocol involving the treatments just mentioned. Measures were taken at baseline and posttreatment and at 3-, 6-, and 12-month follow-up. All treatment conditions were statistically and clinically effective in reducing self-reported panic-agoraphobia symptoms over the 1-year follow-up. No statistical differences were observed between imipramine and placebo conditions. This study found that all treatment modalities helped reduce panic and agoraphobic symptomatology over a 1-year follow-up period. These surprising results support the need to document the relations among the various components of an intervention. This would make it possible to assess the relative efficacy of the treatment components rather than of the intervention as a whole.     

Canadian Immigrants’ Access to a First Job in Their Intended Occupation

Using detailed information on employment trajectory provided by the Longitudinal Survey of Immigrants to Canada, this study examines the labor market outcomes of recent immigrants in terms of the duration until access to a first job in their intended occupation, as determined by a question in the first wave interview on labor market intentions. The matching between actual and intended occupations is obtained from the first two digits of the National Occupational Classification codes, which consider successively occupation type and skill level. Using a Cox proportional hazards model, the study investigates the roles of factors related to human and social capital in speeding up the matching process between actual and intended occupations. It is found that the initial year in Canada is critical for an immigrant to land a job in the intended field; after that period, the hazards of finding employment in the intended occupation flatten down. In general, those with intention to work in nonprofessional jobs, such as sales and services, trades, transport and equipment operators, primary industry, and processing and manufacturing occupations, enter the first job in the intended occupation more quickly. The results also show that education, English language ability, Canadian work experience, and friend networks facilitate access to the intended occupation.     

Priming outside of awareness and subsequent stimulus identification.

The influence of priming outside of awareness on performance of a color-recognition task was investigated. Using a tachistoscope, a color word that matched ("congruent prime") or did not match ("incongruent prime") the target color or a blank prime was followed by a pattern mask and the target color. Identification performance was superior on the blank prime trials to the congruent prime trials, with performance on the incongruent prime trials being the lowest. A subsequent study included a meaningless (XXX) prime condition, and it was found that meaningless primes interfered with target-color identification more than the congruent and blank prime conditions, but less than the incongruent prime condition, suggesting that primes, in addition to producing semantic activation, impose demands on information-processing capacity of the perceptual system.

Is the learning of goal-directed displacement effector-independent?

The present experiment was designed to investigate whether the learning of goal-directed locomotion is effector independent. To answer this question a bilateral transfer of learning paradigm was used. We wanted to find out whether learning can be transferred from a trained effector system to an untrained one. Sixteen participants were asked to proceed through virtual hallways, while walking on a treadmill or handling of a joystick, in order to cross a pair of oscillating doors. Participants received 1050 training trials on the specific effector system before being transferred to the untrained one. Results indicated a clear transfer from handling to walking and only a moderate transfer from walking to handling. This asymmetrical transfer provides partial support in favor of the effector independent hypothesis. Both the theoretical implications of this work and the possible mediating effect of calibration are discussed.     

Current status of intrathecal antifibrinolytic therapy with p-aminomethylbenzoic acid (PAMBA) in subarachnoid hemorrhages

The blood-brain barrier is barely affected by slight or moderate subarachnoidal bleeding so that the p-aminomethylbenzoic acid (PAMBA) administered systemically for antifibrinolytic therapy does not attain the continuous level necessary in the cerebrospinal fluid. Thus the antifibrinolytic agent should be applied intrathecally because this would totally inhibit fibrinolytic activity in cerebrospinal fluid containing blood and during the wound healing of ruptured aneurysmas. The improvement in wound healing reduces the occurrence of rebleeding, especially during the first 10 days, and improves conditions for successful surgical intervention.     

Spatial and temporal adaptations that accompany increasing catching performance during learning

The authors studied changes in performance and kinematics during the acquisition of a 1-handed catch. Participants were 8 women who took an intensive 2-week training program during which they evolved from poor catchers to subexpert catchers. An increased temporal consistency, shift in spatial location of ball-hand contact away from the body, and higher peak velocity of the transport of the hand toward the ball accompanied their improvement in catching performance. Moreover, novice catchers first adjusted spatial characteristics of the catch to the task constraints and fine-tuned temporal features only later during learning. A principal components analysis on a large set of kinematic variables indicated that a successful catch depends on (a) forward displacement of the hand and (b) the dynamics of the hand closure, thereby providing a kinematic underpinning for the traditional transport-manipulation dissociation in the grasping and catching literature.
