亚健康中抑郁程度人群分布特点的对应分析

为了分析亚健康人群抑郁的不同表现程度与不同人口学资料的关系,采用"亚健康状态的测量及诊断标准研究"课题组调查的中国人亚健康资料,利用对应分析对抑郁表现因子总分的不同等级与不同的年龄、婚姻、职业和学历的关系进行分析。结果显示,20岁～30岁、未婚、学生和大专及以上学历主要表现为中重度抑郁倾向,31岁～40岁、已婚、专业人士和高中专学历主要表现为中度抑郁倾向,41岁～60岁、工人、农民和初中以下学历的抑郁倾向较轻,结论为亚健康人群的心理不适,特别是抑郁倾向,主要集中在年龄较轻、学历较高的专业人士和白领人群当中,还包括大学生群体,我们应该针对这些群体采取相应的措施减轻他们的心身不适。     

Supercapacitor behaviour of cobalt-doped nickel oxide films

Ordered nanostructured cobalt-doped nickel oxide films were prepared on a conducting glass substrate via the sol–gel dip-coating method. X-ray diffraction analysis shows the films to be amorphous. Field-emission scanning electron microscope images showed well-defined, ordered grains with pores in between them. Supercapacitor behaviour was studied using cyclic voltammetry. A maximum specific capacitance of 1982?F/g at a scan rate of 5?mV/s with 1?M KOH was obtained for 5?wt% of cobalt-doped nickel oxide films. AC impedance analysis showed that the solution resistance was R _s?=?27?Ω and the charge transfer resistance R _ct?=?20?Ω.     

Deformation of nanograined Ni–60Co alloy with low stacking fault energy

The evolution of deformation texture in a Ni–60Co alloy with low stacking fault energy and a grain size in the nanometre range has been investigated. The analyses of texture and microstructure suggest different mechanisms of deformation in nanocrystalline as compared to microcrystalline Ni–60Co alloy. In nanocrystalline material, the mechanism responsible for texture formation has been identified as partial slip, whereas in microcrystalline material, a characteristic texture forms due to twinning and shear banding.     

Task-defined associations are mode specific for selection of relevant dimension but mode independent for selection of location mapping

When compatible and incompatible mappings of a location-relevant task are mixed, or a location-relevant task is mixed with a task for which stimulus location is irrelevant, the benefit of the compatible mapping is eliminated for physical locations and enhanced for location words. Two experiments examined the influence of presenting the location information for the mixed conditions in different stimulus modes (physical location or word). Experiment 1 showed that the effects of mixing location-relevant and location-irrelevant tasks on the spatial compatibility and Simon effects are reduced when the location information is presented in different modes for the two tasks. Experiment 2 showed, in contrast, that the mode distinction had little influence on the effects of mixed compatible and incompatible mappings for location-relevant tasks: The compatibility effect was eliminated for physical locations and enhanced for words, as when there is no mode distinction. Thus, when location is relevant for one task and colour for the other, the task-defined associations of locations to responses are mode specific, but when location is relevant for both tasks, the associations are mode independent.     

Rethinking Professional Ethics in the Cost-Sharing Era

Changes in healthcare financing increasingly rely upon patient cost-sharing to control escalating healthcare expenditures. These changes raise new challenges for physicians that are different from those that arose either under managed care or traditional indemnity insurance. Historically, there have been two distinct bases for arguing that physicians should not consider costs in their clinical decisions—an “aspirational ethic” that exhorts physicians to treat all patients the same regardless of their ability to pay, and an “agency ethic” that calls on physicians to be trustworthy advisors to their patients. In the setting of greater patient cost-sharing, physicians' aspiration and agency roles increasingly conflict. Satisfactorily navigating the new terrain of consumer-driven healthcare requires physicians to consider these two roles and how they can best be reconciled so as to maximize quality of care while respecting the heterogeneity of patients' financial resources and willingness to pay.     

Don't throw the bathwater in with the baby

The Presidential Address of the European Association of Developmental Psychology, Goossens (2012, this issue), this year concerned how genes and environments interplay to shape loneliness and other developmental psychological relevant outcomes. This is a very welcome. However, when developmental psychology is now ready to integrate recent genetic and neuroscience knowledge and methods, I think it would be very wise not to go uncritically through the mistakes that have been made in other disciplines and instead to learn from their hard lessons. I discuss some problems (genes vs. environments, identifying genes for a phenotype, environmental causes of developmental outcomes, and gene×environment interaction and epigenetics) and some suggestions for solutions that can be used to avoid throwing the bathwater in with the baby.     

Could Balint Have Done More for Ferenczi?

After Ferenczi's death of pernicious anemia in 1933 at the age of 59, Michael Balint became the greatest advocate of his late analyst, teacher, colleague, and friend. He was faced with widespread avoidance, a conspiracy of silence against Ferenczi in the psychoanalytic movement. Ernest Jones, in particular, an analysand of Ferenczi and fellow member of the Secret Committee founded by Freud before World War I, seriously attacked Ferenczi. In the third volume of the Freud biography, Jones alleged that in the last years of his life Ferenczi suffered mental deterioration caused by the pernicious anemia, and that this mental decline was the real cause of Ferenczi's technical experimentations, thereby belittling the importance of Ferenczi's independent work in the last phase of his life. This article answers whether Michael Balint, who later became the literary executor of Ferenczi, was devoted enough in countering the charges that lead to a fifty-year silence on Ferenczi's eminent place in psychoanalysis. Correspondence between Balint and Jones is cited, as are reports of Ferenczi's contemporaries; Balint's efforts are placed within the context of the psychoanalytic rivalries after Freud's death.     

Analysis of discriminative control by social behavioral stimuli

Visual discriminative control of the behavior of one rat by the behavior of another was studied in a two-compartment chamber. Each rat's compartment had a food cup and two response keys arranged vertically next to the clear partition that separated the two rats. Illumination of the leader's key lights signaled a “search” period when a response by the leader on the unsignaled and randomly selected correct key for that trial illuminated the follower's keys. Then, a response by the follower on the corresponding key was reinforced, or a response on the incorrect key terminated the trial without reinforcement. Accuracy of following the leader increased to 85% within 15 sessions. Blocking the view of the leader reduced accuracy but not to chance levels. Apparent control by visual behavioral stimuli was also affected by auditory stimuli and a correction procedure. When white noise eliminated auditory cues, social learning was not acquired as fast nor as completely. A reductionistic position holds that behavioral stimuli are the same as nonsocial stimuli; however, that does not mean that they do not require any separate treatment. Behavioral stimuli are usually more variable than nonsocial stimuli, and further study is required to disentangle behavioral and nonsocial contributions to the stimulus control of social interactions.     

Informant impressions of retardate personality: reliability with extraversion, emotionality, toughmindedness

To assess extraversion, emotionality and toughmindedness among retarded persons with limited linguistic skills the 18-item Personal Reactions and Habits Questionnaire (PRHQ) was created. The responses of 2 interviewed informants, each well acquainted with a target person, are summed to obtain scores for each of the personality factors identified by Eysenck and Eysenck (1975). To establish the reliability of this procedure 4 interviewers inquired of 35 informants about a total of 54 target Ss of a wide range of mental retardation and living variously in the natural home, a group home or in a large state-operated institution. One-week test-retest reliability coefficients, e.g. r=0.93 for Extraversion, r=0.86 for Emotionality and r=0.92 for Toughmindedness, suggest the PRHQ to be a promising instrument for research on personality of Ss unable to provide self-reports. The possible use of the PRHQ to assess concordance of self-reports with personality impressions of others is also discussed.
