Speed of Processing and Face Recognition at 7 and 12 Months

This research examined developmental and individual differences in infants' speed of processing faces and the relation of processing speed to the type of information encoded. To gauge processing speed, 7‐ and 12‐month‐olds were repeatedly presented with the same face (frontal view), each time paired with a new one, until they showed a consistent preference for the new one. Subsequent probe trials assessed recognition of targets that either preserved configural integrity (Study 1: 3/4 profile and full profile poses) or disrupted it while preserving featural information (Study 2: rotations of 160° or 200° and fracturings). There were developmental differences in both speed and in infants' appreciation of information about faces. Older infants took about 60% fewer trials to reach criterion and had more mature patterns of attention (i.e., looks of shorter duration and more shifts of gaze). Whereas infants of both ages recognized the familiar face in a 3/4 pose, the 12‐month‐olds also recognized it in profile and when rotated. Twelve‐month‐olds who were fast processors additionally recognized the fractured faces; otherwise, processing speed was unrelated to the type of information extracted. At 7 months then, infants made use of some configural information in processing faces; at 12 months, they made use of even more of the configural information, along with part‐based or featural information.     

Tempest-tost: Exile,ethnicity, and the politics of rescue

Refugees are individuals forced to flee from their homelands because of categorical persecution or because they are bystanders caught in the crossfire of war or civil strife. Such involuntary exile often leads to alienation in the most literal sense of the term. Whether expellees, escapees, or displaced persons, refugees share a common fate and, often, a common destiny: those who are dispossessed are dependent on others to provide care, succor, protection, and assistance. Yet responses to their plight are almost invariably highly selective, the quality of mercy being strained by considerations other than pure altruism. This paper, a commentary on the sociology of exile, attempts to convey the sense and significance of estrangement and responses to it in both historical and contemporary contexts. Early sections deal with concepts and concerns; later ones examine United States refugee policies and practices relating to exile, ethnicity, and the politics of rescue.Presidential address presented at the Eastern Sociological Society annual meeting, Arlington, Virginia, April 1992. Some parts of the address have appeared in different form in other publications by the author (see Rose, 1981, 1984, 1991).     

“You Just Might Get It Right One Day”: On Being Informed By Carl J. Couch

The founders of the intellectual tradition that became known as symbolic interaction theory were the first to articulate the principle that society exists in communication…. Let us focus our analytic powers on social acts.     

Two permutation tests of equality of variances

The F-ratio test for equality of dispersion in two samples is by no means robust, while non-parametric tests either assume a common median, or are not very powerful. Two new permutation tests are presented, which do not suffer from either of these problems. Algorithms for Monte Carlo calculation of P values and confidence intervals are given, and the performance of the tests are studied and compared using Monte Carlo simulations for a range of distributional types. The methods used to speed up Monte Carlo calculations, e.g. stratification, are of wider applicability.     

Living with the stigma of AIDS

This article uses interview data to explore how 23 gay and bisexual men who had AIDS were affected by and managed stigma. The article describes how stigma affects the relationships of persons with AIDS to their families, friends, lovers, colleagues, and health care providers. It explores how persons with AIDS avoid or reduce stigma by concealing their illnesses, learning when and to whom they should reveal their illnesses, changing their social networks, educating others about AIDS, developing nonstigmatizing theories of illness causation, and using bravado to convince others that they are still functioning social beings.     

Unemployment classifications and subjective well-being

Further research on the impact of unemployment on workers and their families requires greater refinement and more precise measurement of the concept. While previous studies have indicated the effects of unemployment on a wide range of variables, such as health and well-being, many of these studies suffer from imprecision by conceptualizing unemployment too narrowly and by using too strict a dichotomy between currently employed and currently unemployed workers. This research effort attempts to broaden and refine the concept of unemployment by defining it in terms of two job dimensions: current employment status and previous job loss. Using this conceptualization, the authors find that current unemployment after other job losses may have more devastating effects on well-being than losing one's job for the first time. Similarly, among the currently employed, those who have lost jobs in the past may experience more emotional difficulties than those who have never lost their jobs.     

大家都是过来人

最近跟朋友聊天,大家最关心的话题就是找工作了,因为都是初入职场,所以大家都渴望互相多交流一些情况。一般问起“工作、薪水”来,大家都挺愿意说的,不过至于说的内容里有没有水分我无法判断。我个人也只是问问,心里有个底,别人工作的好坏、薪水高低我是不会作评价的。因为我不看重这个,我想要的是经验,钱少点、工作累点都没     

A Modified Knox Test of Space-Time Clustering

Tests of space-time clustering such as the Knox test are used by epidemiologists in the preliminary analysis of datasets where an infectious aetiology is suspected. The Knox test statistic is the number of cases close in both space and time to another case. The test statistic proposed here is the excess number of such cases over that expected under H₀ of no infection. It is argued that this modified test is more powerful than the Knox test, because the test statistic is not heavily tied as is the Knox test statistic. The use of the test is illustrated with examples.
