在崩溃家庭中自我救赎——谈柳美里《家梦已远》中的人物和主题

《家梦已远》是柳美里的一部反映家庭崩溃主题的小说。主人公＂我＂面对＂改邪归正＂的父亲的＂热情＂,期望能借着留住新屋之际来追想失落的家庭,却在理想与现实中飘忽不定。小说通过描写母亲、妹妹、＂我＂、父亲对新居的对立看法及行为,揭示了崩溃家庭的不可挽回。作者用几乎不带感情色彩的客观叙述,突出了主人公对＂家梦已远＂的无奈,并由此体现柳美里作品的＂个人化＂特点和＂家庭＂主题。     

基于SVM的多生物特征融合识别算法

针对单生物特征识别的局限性,提出融合手背静脉和虹膜两种生物特征实现身份识别.基于尺度不变特征变换(SIFT)提取手背静脉的局部SIFT特征并对特征点进行匹配,利用特征匹配率作为手背静脉图像的相似度测度.通过Haar小波变换实现虹膜特征编码,利用加权汉明距对虹膜进行相似度测试.最后基于支持向量机(SVM)实现两种生物特征在匹配层的融合识别.利用CASIA虹膜数据库和TJU手背静脉数据库对算法性能进行测试,其等错率为0.02%,实验结果表明,该融合算法具有很高的识别性能,为生物特征识别研究提供了新思路.     

“I have always thought about death, a death that I might give myself”.

This article, as well as the publication of a previously unpublished personal letter written by Jacques Derrida in his youth, relate to my thinking and research regarding the existential questions raised by philosophy and the act of suicide. Both the personal letter and the correspondence between Derrida and his close friend Michel Monory invite us to reflect on death and the enigma that suicidal ideation can take when presenting itself to a subject, while at the same time they provide us with valuable information about the origins of Derrida's oeuvre to come. Giving us a glimpse into the universe of a young tormented soul, who has already dreamed of “a book of extraordinary philosophy,” Jacques Derrida confides some of his philosophical, psychological, and—interesting in light of what we know will be his future—autobiographical reflections to his friend. I situate the context of this correspondence more precisely and give shape to the distant, buried form of what will have been friendship allowing us to gain a greater understanding of the act of autobiography, as well as the autobiographical pact—as Philippe Lejeune has theorized it—and how it relates to the work of mourning.

Toward a more complete understanding of the effects of personal mastery on cardiometabolic health.

Objective: A great deal of research has been devoted to identifying the psychological factors that might be associated with reduced risk for cardiovascular diseases. In particular, coping resources such as personal mastery might attenuate stress-related pathophysiology. The purpose of the present review was to examine the existing literature reporting associations between personal mastery and cardiometabolic health outcomes to determine which outcomes have been studied to date, investigate the extent of inconsistency in the literature, and propose new directions for research. Design: Systematic review of articles examining the associations between personal mastery and cardiometabolic health. Main Outcome Measures: Studies were included if they examined objective measures of cardiometabolic function, cardiovascular events, and/or mortality. Results: Thirty-two studies were identified examining the effect of mastery on the following outcomes: mortality and/or cardiovascular events, psychoneuroendocrine stress systems, cardiovascular reactivity to acute stress, metabolic dysregulation, inflammation/coagulation, and evidence of large vessel disease from imaging methods. Conclusions: Overall, mastery was associated with better cardiometabolic health and reduced risk for disease and/or death, typically with a small-medium effect size. A relatively small proportion of studies reported contradictory findings that higher mastery was associated with poorer cardiometabolic outcomes. The state of the current research suggests that future investigations should focus on 1) clarifying the mediators and moderators most relevant in the association between mastery and downstream disease, 2) testing the association between mastery and biological outcomes longitudinally, 3) examining the physiological impact of mastery-increasing interventions, and 4) studying the relationship between mastery and disease risk in diverse ethnic or sociocultural groups.

Estimating person-to-person variability in VOC emissions from personal care products used during showering

An increasing fraction of volatile organic compounds (VOC) emissions come from the domestic use of solvents, contained within myriad commonplace consumer products. Emission rates are often poorly characterized and depend significantly on individual behavior and specific product formulation and usage. Time-concentration profiles of volatile organic compounds (VOCs) arising from the use of a representative selection of personal care products (PCPs) during showering are generated, and person-to-person variability in emissions calculated. A panel of 18 participants used a standardized set of products, dosages, and application times during showering in a controlled indoor bathroom setting. Proton transfer mass spectrometry was used to measure the in-room VOC evolution of limonene (representing the sum of monoterpenes), benzyl alcohol, and ethanol. The release of VOCs had reproducible patterns between users, but noticeable variations in absolute peak concentrations, despite identical amounts of material being used. The amounts of VOC emitted to air for one showering activity were as follows: limonene (1.77 mg ± 42%), benzyl alcohol (1.07 mg ± 41%), and ethanol (0.33 mg ± 78%). Real-world emissions to air were between 1.3 and 11 times lower than bottom-up estimates based on dynamic headspace measurements of product emissions rates, likely a result of PCPs being washed away before VOC evaporation could occur.

Personal resources and political uprooting: The Israeli experience.

The authors assessed distress in Israeli society before and after Israel’s disengagement from Gaza and the northern West Bank during the summer of 2005. Random samples of 701 Israelis residing in various parts of Israel (Study 1) and 246 Israelis residing in Gaza and the northern West Bank who were to be uprooted (Study 2) were interviewed by telephone several weeks before the disengagement (T1), with 462 and 124 of these respondents, respectively, reinterviewed several weeks after the disengagement (T2). Anxiety related to the national and security situation was lower at T2 than at T1 in both studies. A personal resource, namely mastery–optimism, contributed negatively to both anxiety and hostility before the disengagement in both studies. In Study 1, it also predicted lower postdisengagement anxiety. The findings underscore the importance of mastery–optimism in the adjustment to threatening political events such as forced uprooting.

Review of Revitalizng retirement: Reshaping your identity, relationships, and purpose.

Reviews the book, Revitalizng retirement: Reshaping your identity, relationships, and purpose by Nancy K. Schlossberg (2009). Therapists, counsellors, and life coaches working with older middle-age adults will find this handbook to happiness in retirement a useful working tool. The author introduces the book by stating that some content resembles notes she resurrected from a freshman undergraduate lecture on personal development; accordingly, both the format and the issues discussed in this book generalise to life span motivational needs, but the intended focus is on the transition to retirement. As a result, this book would make a useful tool for a support group or workshop on psychosocial transitions in postemployment life, with some limitations.

Emission rates and the personal cloud effect associated with particle release from the perihuman environment

Inhalation exposure to elevated particulate matter levels is correlated with deleterious health and well‐being outcomes. Despite growing evidence that identifies humans as sources of coarse airborne particles, the extent to which personal exposures are influenced by particle releases near occupants is unknown. In a controlled chamber, we monitored airborne total particle levels with high temporal and particle‐size resolution for a range of simulated occupant activities. We also sampled directly from the subject's breathing zone to characterize exposures. A material‐balance model showed that a sitting occupant released 8 million particles/h in the diameter range 1‐10 μm. Elevated emissions were associated with increased intensity of upper body movements and with walking. Emissions were correlated with exposure, but not linearly. The personal PM₁₀ exposure increment above the room‐average levels was 1.6‐13 μg/m³ during sitting, owing to spatial heterogeneity of particulate matter concentrations, a feature that was absent during walking. The personal cloud was more discernible among larger particles, as would be expected for shedding from skin and clothing. Manipulating papers and clothing fabric was a strong source of airborne particles. An increase in personal exposure was observed owing to particle mass exchange associated with a second room occupant.
