Trafficking women: Gendered impacts of Canadian immigration policies

Women and men are subject to different forms of human trafficking; sexual exploitation is more common for women than for men, and the purposes of trafficking follow gender roles. This article argues that Canadian immigration policies have differential and discriminatory impacts according to gender. We define human trafficking before critiquing two Canadian immigration programs that leave women vulnerable to exploitation. Interviews, questionnaires, and a review of official documents were employed in exploring the government's response to this phenomenon. Our findings suggest that given the nature of the international trafficking and exploitation of women in Canada, the government's focus on border control is ineffective in protecting trafficked women's human rights and the rights of migrants generally.     

Sex-dependent effects of neonatally administered morphiceptin and D-ala-D-leu-enkephalin on maze learning in rats

Newborn rats were injected (ip) with morphiceptin [72.7 micrograms/kg (a mu-type opioid receptor agonist)], D-alanine2-D-leucine5-enkephalin [79.4 micrograms/kg (a delta-receptor agonist)], or saline for 7 days after birth. Testing on a complex maze on Day 25 revealed a significant sex-dependent facilitation of performance by the opioid peptides. Peptide-treated females performed better than the males on the first day of training as measured by errors. Opioid treatment increased mortality, as three times as many peptide-treated animals died in comparison to the saline control group. Peptide treatment did not affect locomotor activity measured in an open field. Weight at Day 24 was also affected by the peptide treatment, females and males injected with the opioids being lighter and heavier, respectively, than the control group.     

Age-related memory deficits in rats and mice: enhancement with peripheral injections of epinephrine

Epinephrine peripherally administered to rats and mice immediately following avoidance and/or appetitive training enhances later memory retention in both young and old animals. These findings suggest a possible involvement of peripheral adrenergic systems in memory dysfunctions which accompany aging.     

Cartoons varying in low-level pain ratings,not aggression ratings,correlate positively with funniness ratings

In three studies, cartoons were rated for aggression, pain, and funniness in order to determine whether aggression, pain, or both correlated with funniness and whether a positive or inverted-U function described the relationship. Pain correlated more reliably with funniness than did aggression. A probable explanation for this is that cartoons showed greater variability in pain than in aggression ratings, since pain could be self-inflicted or could result from a mishap or from another's aggression. Funniness increased to asymptote within the first third of the pain dimension and was unaffected by further pain increases. No significant downward trend in funniness was observed with increased pain ratings. The results were interpreted by assuming that cartoon violence is a salient dimension, in which to create discrepancies, and that the discrepancies were reflected in the pain ratings.These studies were supported by Ball State University Research Grants.     

Determinants of tax evasion and compliance

The problem of tax evasion and subsequent revenue loss is an important one for our nation. Noncompliance with tax laws causes multibillion dollar annual losses for the U.S. treasury. An investigation of psychological variables is suggested as the most promising route to increase tax compliance. Hence, a review of the legal, economic, sociological, and psychological literature concerning the motivation and causes of noncompliance with tax laws is presented. Theoretical models and empirical studies addressing the issue of tax evasion are reviewed. An individual's feelings of equity and sense of norm commitment may be the crucial factors in the decision to comply or evade legally mandated taxes, superseding the notion of sanctions as the most effective deterrent. A legal reasoning model is one suggested alternative in the search for a causal explanation of noncompliance.     

关于同化和对比错觉的实验研究

本文以Delbouef同心圆错觉图为材料,应用认知方式,控制注意,改变刺激和注视条件等变量,在三个实验中考察了同化错觉和对比错觉在机制上的区别和联系。结果发现,场依存性认知方式特征与同化错觉有显著正相关,对比错觉反之。利用指示语控制被试注意于测验成分时,显著的错觉减弱只出现在对比图形中。此外,在一般指示下两种错觉都因背景成分减弱轮廓的亮度对比而减弱,但在选择性指示的条件下,类似减弱只出现在同化错觉中。视角加大时显著地减弱同化错觉,却加大对比错觉。使用“减弱错觉”方法,即在多次连续判断中减小错觉量只在超中央窝(大视角)的观看条件下有显著效应。所有这些结果都难于用错觉产生的生理学模式和单因素认知模式来说明。因此,我们认为错觉是一种复杂的知觉加工活动的产物。在已有的各种错觉理论中,合成的认知性“集合与存储”模式(“Pool and Store Model”,Coren & Girgus,1978)似乎是最好的解释。     

Vocal congruence in mother-infant play

Turn-taking is the fundamental temporal structure of adult dialogue. This structure defines two types of joint silence: intrapersonal pause (silence bounded by the vocalizations of a single speaker) and switching pause (silence bounded by the vocalizations of different speakers). Switching pauses mark the boundaries of the turn exchange. In adult conversation the mean durations of both types of pause are characteristically matched between partners. This matching, termed vocal congruence, occurs developmentally earlier in the case of switching pauses. We hypothesized and confirmed that mothers and infants match switching pauses but not intrapersonal pauses at 4 months, even though the infants' vocalizations are prelinguistic. Second, since there are known affective correlates of vocal congruence in adult conversation, we hypothesized a similar affective correlate for mother-infant vocal congruence. We found, for the intrapersonal pause only, that the degree of matching within a dyad correlated with infant affective engagement. We conclude, from switching pause congruence, that a turntaking dialogic structure is being regulated in the mother-infant pair at 4 months in the same way as seen in adult conversation. Thus, both the temporal structure of adult dialogue and its affective correlate are prelinguistic.Supported in part by NIMH grant No. 41675.
