Global demand for human ova in in vitro fertilization has led to its expansion in countries with falling average incomes and rising female unemployment. Paid egg donation in the context of national, regional, and global inequalities has the potential to exploit women who are socioeconomically vulnerable, and indeed there is ample evidence that it does. Structural injustices that render women in middle-income countries – and even some high-income countries – economically vulnerable contribute to a context of ‘omissive coercion’ (Wilkinson 2003 Wilkinson, S. 2003. “The Exploitation Argument Against Commercial Surrogacy.” Bioethics 17 (2): 169187. doi: 10.1111/1467-8519.00331[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) that is morally troubling. When egg brokers or fertility clinics take advantage of these background structural injustices and prospective ova providers’ vulnerability in order to pay them less than they need to meet their livelihood needs, they engage in exploitation. Analyzing paid egg donation as a form of reproductive labor, however, can direct our attention to reforms that would reduce exploitative instances of this practice. In contrast to those who see egg provision as inescapably commodifying and harmful, I argue that compensated egg provision can be made less exploitative. I defend my approach against commodification-driven analyses of egg donation and concerns about undue inducement, and conclude by discussing some of the ways in which policy-makers and medical practitioners might reduce the harms that may result from this global practice.  相似文献

Using extensive diary data from people taking their driver's license exam, the authors investigated the role of time in affective forecasting accuracy. Replicating existing findings, participants grossly overestimated the intensity and duration of their negative affect after failure and only slightly overestimated the intensity and duration of their positive affect after success. Extending existing findings, participants accurately predicted a decrease of their affective reactions over time but underestimated the speed with which this decrease would occur. In addition, they showed greater forecasting accuracy for positive affect than negative affect when the exam was distant and greater forecasting accuracy for negative affect than positive affect when the exam was close. The motivational processes underlying these findings are being discussed.  相似文献

This study reports an investigation of the relationships of work hours, job complexity, and control over work time to satisfaction with work-family balance. Based on data from a sample of 570 telephone call center representatives, a moderated hierarchical regression analysis revealed that work hours were negatively related to satisfaction with work-family balance, consistent with the resource drain perspective. Job complexity and control over work time were positively associated with satisfaction with work-family balance. Control over work time moderated the relationship such that as work hours rose, workers with low control experienced a decline in work-family balance satisfaction, while workers with high control did not. Results encourage greater research attention to work characteristics, such as job complexity and control over work time, and skills that represent resources useful to the successful integration of work and family demands.  相似文献

Despite numerous body size estimation studies, it cannot be concluded that the disturbance of body image in anorexia nervosa (AN) is specifically one of the visual body images.We adopted a visual imagery method, the Distance Comparison task, to enable across-population testing of differences in visual body image with respect to shape. Participants were asked to mentally scan across two body widths (e.g. hips and shoulders) and to decide as quickly as possible which one was longer or shorter. If the mental representation accessed to make such comparisons is visual, an inverse relation would be expected between RT and distance difference on the body to be judged (i.e. actual difference in size between the two body widths), with accuracy increasing with increasing distance difference. Females with high body shape concern (scoring high on the Body Shape Questionnaire: BSQ, n = 23) were compared to females with low body shape concern (scoring low on the BSQ, n = 19).RT and distance differences on the body demonstrated standard distance differences effects: RT increased and accuracy decreased with decreasing distance differences on the body. Groups differed with respect to accuracy, in that females high on body shape concern were significantly less accurate than females low on body shape concern when making evaluations involving small (?9 cm) differences, which implies a less appropriate visual image of the own body in the former group. With respect to the relation between RT and body distance difference, on the other hand, there were no differences between groups. We concluded that evaluations of own body size employ visual imagery and that the distance comparison task holds promise for the assessment of visual disturbances in body image in clinical populations.  相似文献

In post‐Fordist economies, the nature of laboring activities can no longer be subsumed under a Taylorized model of labor, and the service sector now constitutes a larger share of the market. For Maurizio Lazzarato, Michael Hardt, Antonio Negri, and other theorists in the post‐Marxist tradition, labor has changed from a commodity‐producing activity to one that does not produce a material object. For these authors, this new type of labor is immaterial labor and entails communicative acts as well as added worker agency. This paper reflects on this new paradigm of labor by examining the paid practices of care defined as the activities performed by individuals who have a mandate to help another adult accomplish the tasks of self‐care. Because care workers take care of other bodies, care labor exemplifies an embodied practice. I make use of the corporeality of care to put forward the notion of thin and thick embodiment in order to examine critically the meaning of immaterial labor and to support my claim that immaterial labor, as conceptualized by Hardt and Negri, erases both the materiality and relationality of care labor. Furthermore, typifying care labor as immaterial only serves to maintain its marginalized status. Care Assistant. Required to work within a private residential center to assist nursing staff.

Children with 22q11.2 deletion syndrome (22q11DS; velo-cardio-facial-syndrome) are at risk for the developmental disorders, attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). In this study, the relation between executive functioning (EF) and the severity of ADHD and ASD symptoms is examined, since EF is known to be important in relation to emotional and behavioral problems. The participants consist of 58 children (38 females) with a mean age of 13.5 years (SD 2.6). Standardized assessment was used to evaluate the severity of ASD and ADHD symptomatology. The major aspects of EF, i.e., cognitive flexibility, inhibition, sustained attention, distractibility, working memory and reaction speed, were evaluated. The profile of EF in 22q11DS was found to be characterized by weaker performance compared to the norms on all subdomains of EF. Poor cognitive flexibility and inhibition, as well as high distractibility, were found to be related to more severe ASD symptoms, while poor quality of sustained attention and high distractibility were found to be related to more severe ADHD symptoms. It is concluded that children with 22q11DS experience impairments in EF, and that the degree of impairment on specific EF subdomains is related to the severity of ASD and/or ADHD symptomatology. These results may help in defining the mediating role of neurocognitive dysfunctions in the development of social and behavioral problems in 22q11DS.  相似文献

In patients with the callosal type of anarchic-hand syndrome, the left hand often does not act as intended and counteracts the right hand. Reports are scarce about the underlying neurophysiological mechanisms. We report the case G.H. who developed the syndrome after infarction of the left arteria pericallosa. It has been suggested that the syndrome arises out of lacking inhibition from the dominant left hemisphere on the right hemisphere. Yet, in tests of spatial intelligence G.H. performed much better with his “anarchic” left hand than with his dominant right hand, similar to observations commonly reported in split-brain patients. Left-right manual choice responses and event-related EEG potentials to laterally presented stimuli were measured. Asymmetries were evident in G.H.’s behavior and EEG potentials, different from age-matched healthy participants (n = 11). His right-hand responses were fast and unaffected by incompatibility with stimulus location, whereas his left-hand responses were variable and accompanied by a large negative central-midline EEG potential, probably reflecting efforts in initiating the response. G.H.’s visual N1 component peaked earlier and was larger at the right than the left side of the scalp, and the P3 component was distinctly reduced at the right side. Both features occurred independent of side of stimulus presentation and side of responding hand. The effort indicated by the midline negativity and the asymmetrically reduced P3 might directly reflect G.H.’s lack of control on his right hemisphere’s processing. The faster visual processing of the right hemisphere suggested by the N1 asymmetry might contribute to “anarchic” processing, making the right hemisphere process stimuli before control impulses exert their effect. These neurophysiological results tend to support the split-brain account which assumes that the syndrome arises by the lack of communication between hemispheres that act according to their respective competences.  相似文献
