In this essay several virtues are discussed that are needed in people who work in participatory design (PD). The term PD is used here to refer specifically to an approach in designing information systems with its roots in Scandinavia in the 1970s and 1980s. Through the lens of virtue ethics and based on key texts in PD, the virtues of cooperation, curiosity, creativity, empowerment and reflexivity are discussed. Cooperation helps people in PD projects to engage in cooperative curiosity and cooperative creativity. Curiosity helps them to empathize with others and their experiences, and to engage in joint learning. Creativity helps them to envision, try out and materialize ideas, and to jointly create new products and services. Empowerment helps them to share power and to enable other people to flourish. Moreover, reflexivity helps them to perceive and to modify their own thoughts, feelings and actions. In the spirit of virtue ethics—which focuses on specific people in concrete situations—several examples from one PD project are provided. Virtue ethics is likely to appeal to people in PD projects because it is practice-oriented, provides room for exploration and experimentation, and promotes professional and personal development. In closing, some ideas for practical application, for education and for further research are discussed.  相似文献

Verbal responses, gestures, and other physical stimuli are often used to prompt children to pay attention to their teacher, participate in group responding, and engage in independent activities in the classroom. Prompts can be intrusive and draw attention to the problem, however. In the present study, unobtrusive vibrating pagers were used to discreetly alert children to attend directly to the teacher or the ongoing activity, thus reducing the number of disruptions the children created in their classrooms. The children were then able to learn more effectively and with less interference to others in the vicinity. Specifically, 5 male children, between 4 and 7 years old, who attended a regular education preschool or regular education first-grade classroom, participated. An alternating baseline and treatment conditions design was used, in which periods of overt traditional prompting were alternated with periods of covert tactile and overt traditional prompting. The data showed that covert tactile prompting was successful in reducing the amount of overt traditional prompting that was needed for attention to a teacher, group responding, and engagement in independent activities.  相似文献

Serotonergic and opiate interactions in the modulation of drug- and environmental-induced analgesia were assessed in 6-day-old Sprague-Dawley-derived rat pups using tail-flick testing procedures. In these experiments the serotonergic antagonist metergoline was observed to attenuate both the analgesia induced by the opiate agonist morphine and the analgesia induced by isolation from siblings and the dam, an environmental manipulation which has previously been shown to be associated with increases in opiate activity. In contrast, the opiate antagonist naloxone was observed to be ineffective in blocking not only analgesia induced by the serotonergic agonist quipazine, but also analgesia induced by long-term deprivation from the dam and food, a manipulation that has been previously reported to induce increases in serotonergic utilization. These results suggest that in the neonate, as in the adult, the serotonergic modulation of nociception appears to occur "downstream" from the opiate systems serving to regulate nociception following both drug- and environmental-induced alterations in pain sensitivity. Analgesia induced by long-term deprivation from food and the dam appears to be strongly related to increases in serotonergic activity and relatively unaffected by opiate antagonism, whereas analgesia induced by isolation from siblings and the dam may be related to increases in opiate activity, but modulated by serotonergic systems serving to regulate pain responsivity. Thus alterations in the environment, mediated at least in part by alterations in opiate and serotonergic activity, appear to play an important role in influencing the sensitivity of the neonate to pain stimuli.  相似文献

This study explored differences between homeless male veterans in metropolitan and micropolitan cities in Nebraska on sociodemographic, housing, clinical, and psychosocial characteristics as well as health service use. A convenience sample of 151 homeless male veterans (112 metropolitan, 39 micropolitan) were recruited from Veterans Affairs facilities and area shelters in Omaha, Lincoln, Grand Island, and Hastings in Nebraska. Research staff conducted structured interviews with homeless veterans. Results showed that compared to homeless veterans in metropolitans, those in micropolitans were more likely to be White, unmarried, living in transitional settings, and were far more transient but reported greater social support and housing satisfaction. Veterans in micropolitans also reported more medical problems, diagnoses of anxiety and personality disorders, and unexpectedly, were more likely to report using various health services and less travel time for services. Together, these findings suggest access to homeless and health services for veterans in micropolitan areas may be facilitated through Veterans Affairs facilities and community providers that work in close proximity to one another. Many homeless veterans in these areas are transient, making them a difficult population to study and serve. Innovative ways to provide outreach to homeless veterans in micropolitan and more rural areas are needed.  相似文献

The author reports on a series of integrated studies on melodic contours in infant-directed (ID) speech. ID melodies in speech are taken as an instructive example of intuitive parenting in order to review current evidence on its forms, functions and determinants. The forms and functions of melodic prototypes are compared in terms of universal properties and individual and/or cultural variability across samples of German, Chinese and American mothers, and German mothers and fathers with their 2- and 3-month-old infants. Microanalyses of interactional contexts show that forms and functions of ID melodies are intimately related to typical dimensions of intuitive caregiving–arousing/soothing, turnyielding/turn-closing, approving/disapproving. The communicative functions of ID melodies as both categorical and graded signals are discussed with respect to the current knowledge on infant responses to ID speech and on early speech perception. According to a comprehensive longitudinal study of ID speech in relation to stages of infant vocalization, ID speech results from fine-tuned adjustments in various prosodic and linguistic features to developmental changes in infants' perceptual and vocal competence. ID melodies evidently have the potential to draw infant attention to caregivers' speech, to regulate arousal and affect in infants, to provide models for imitation, to guide infants in practising communicative subroutines and to mediate linguistic information. Current evidence suggests that the melodies in caregivers' speech provide a species-specific guidance towards language acquisition.  相似文献

Underdiagnosis and undertreatment of late-life depression is common, especially in primary care settings. To help assess whether physicians attitude and confidence in diagnosing and managing depression serve as barriers to care, a total of 176 physicians employed in 18 primary care groups were administered surveys to assess attitudes towards diagnosis, treatment, and management of depression in elderly patients, (individuals over 65 years of age). Logistic regression was performed to assess the association of physician characteristics on attitudes. Nearly all of the physicians surveyed felt that depression in the elderly was a primary care problem, and 41% reported late-life depression as the most common problem seen in older patients. Physicians were confident in their ability to diagnose and manage depression, yet 45% had no medical education on depression in the previous three years. Physicians confidence in their ability to diagnose, treat, and manage depression, and their reported adequacy of training, do not appear to correspond to the amount of continuing medical education in depression, suggesting that physician overconfidence may potentially be serving as a barrier to care.  相似文献

The self as a psychological construct, and the self in relation to the other has been discussed in psychological and sociological literature for decades, but not much attention has been given to the psychological development of the self in relation to the social construction of prejudice. The primary aim of this article is to explore the self in prejudice and thus the psychological processes involved in the development of self within the social context. Consequently, the aim is to explore the self in the construction and expression of prejudice from both a social and psychological approach, and to explain selfhood influences at the individual, group and community levels. I use the conceptual framework of Kohut's self psychology as a lens to present the development of the self and thus the idea of the development of the self in relation to the other. In such exploration of self in prejudice, I present some of my ideas which include prejudice as an outcome of self-definition in the context of the other, as well as linking self in prejudice and group dynamics to attachment theory and the notion of “selfgroup’ in terms of overidentification with the in-group. While the social and the psychological in terms of the development of the self cannot be separated, I have therefore attempted to merge at some point the two bodies of thought in relation to the self in prejudice.  相似文献

ne important class of actions concerns tasks. Questions may be raised about whether we have succeeded or failed to do what we were trying to do. Not all the things we call actions are open to considerations of such success or failure. And questions of succeeding or failing are not raised solely about what we may have been trying to do. The paper attempts to classify various ways in which one may fail in an action; the array that results is explored in terms of evaluations rendered, responsibility, character, deliberate decision, and the like. The analysis of failing in what one has tried to do is made central. To be said to be trying to do something, one must have done the requisite things that constitute trying to do something and not to have succeeded yet in doing what one may have tried to do. “Trying to succeed”; in doing something is a redundant expression except for special cases; and though one may decide to try to do something, one cannot decide to succeed in this. One may actually succeed in doing what one has tried to do but one cannot deliberately succeed. Further distinctions are made between trying to do something and wishing to do something and believing that one is trying to do something; also, between failing in what one has tried to do, failing to try, failing to do something without failing in what one has tried to do, and failing to do something in respects in which one could never be said to have tried to do it.  相似文献

Here we tested whether exposure to either tailshock or swim stress alters ovarian hormone levels, estrogen and progesterone, in females and whether the effects are persistent. Adrenal hormone levels were also measured in males and females. Estradiol levels were elevated in unstressed females during proestrus relative to females in other stages of estrous, and exposure to the stressors enhanced estradiol beyond basal levels. For females stressed during diestrus 2, estradiol levels were elevated immediately after stressor cessation and up to 24 hrs. Exposure to tailshock, but not swim-stress, transiently enhanced progesterone in females stressed during the stage of proestrus and estrus. Glucocorticoid levels were elevated in response to both stressors and were supraelevated in females under both basal and stress conditions relative to males, particularly in blood from females exposed to acute swim stress. These results indicate that exposure to a relatively acute stressful event immediately and persistently enhances serum estradiol and are discussed in the context of reports that exposure to the same stressors immediately and persistently impairs associative learning in the female rat.  相似文献

Two studies were conducted to assess appearance-related visual processing mechanisms in populations at risk of disorders characterized by body image disturbance. Using inverted stimuli, Experiment 1 assessed visual processing mechanisms associated with body, face, and house viewing in adolescents. Experiment 2 applied the same protocol to assess appearance-related configural processing in high- and low-risk adolescent women, and women recovering from disorders characterized by body image disturbance. Experiment 1 found evidence for typical configural face and body processing, although adolescent women reported higher levels of body image concern (BIC) and self-objectified to a greater extent than adolescent men. In Experiment 2, typical body inversion effects were seen in the low-risk group, whilst there was some evidence to suggest a disruption to the configural processing of body stimuli in high-risk adolescents and in women recovering from body image disorders. Women in recovery were also quicker to respond to all stimuli, whilst high-risk adolescents took longer to respond to bodies than to other stimuli. Configural face processing was intact in all groups, and effects did not directly relate to BIC or self-objectification. These findings have implications for future research looking to inform early interventions and treatment, suggesting that there could be a tendency to visually process individual body parts at the expense of the whole-body form in women at risk of developing body image disorders, as well as those in recovery.  相似文献

Gender and victimization by intimates   总被引:1,自引:0,他引:1  
Recent data demonstrate that, although gender has an impact upon the experience of being a victim of an intimate's violence, there is no particular personality pattern that leads one to become a victim. Rather, women--who are socialized to adapt and submit, and who are likely to become victims of men's sexual violence or physical abuse--may not develop adequate self-protection skills as children, especially if they come from childhood homes in which females are victimized, leading to a later vulnerability to physical and sexual abuse. Men, however, socialized to express anger and aggression in an outward manner, learn to model the abuse witnessed or experienced in childhood and often learn that women are the "appropriate" recipients of this violence. Social learning theories of modeling and aggression are used to explain how such personality patterns develop, and the theory of learned helplessness is used to explain battered women's coping responses to their partners' abusive behavior. The extreme situation, in which a battered woman kills her partner in self-defense, is analyzed in order to understand women victims' sense of desperation and entrapment in severely abusive relationships and the extent to which their behaviors are in reaction to the abuse perpetrated by the mate.  相似文献

Blocking progesterone’s metabolism to 5α -pregnan-3α -ol-20-one (3α ,5α -THP) with finasteride, a 5α -reductase inhibitor, and effects on anxiolytic, exploratory, and antinociceptive behaviors of rats in behavioral estrus were examined. Rats in behavioral estrus received finasteride systemically (SC), to the hippocampus, or to control implant sites, the nucleus accumbens (NA) or ventral tegmental area (VTA), and were tested in horizontal crossing, open-field, elevated plus-maze, emergence, holeboard, social interaction, tailflick, pawlick, and defensive freezing tasks. Finasteride, SC or intrahippocampally, reduced 3α ,5α -THP in the hippocampus relative to vehicle implants or finasteride to the NA or VTA. Systemic or intrahippocampal finasteride decreased central entries in the open field and open-arm time on the elevated plus-maze and increased freezing in response to shock relative to vehicle. Finasteride to the hippocampus decreased emergence latencies and increased social interaction, pawlick, and tailflick latencies relative to all other groups. Finasteride to the hippocampus of rats in behavioral estrous decreased anxiolysis and enhanced exploration and analgesia. In summary, these data demonstrate that decreases in anxiolytic behavior of behavioral estrous rats can be produced by reductions in 3α ,5α -THP in the hippocampus, which suggest that elevations in 3α ,5α -THP in the hippocampus may give rise to anxiolysis seen during behavioral estrus.  相似文献

To prevent youth violence, the GREAT Families program was implemented with a selective sample of 1,196 families of sixth-grade children from low-income schools in 4 cities making the transition to adolescence. To assess intervention effects, we used pre- and posttest data to estimate a structural model to test the hypothesis that random assignment to the intervention would predict changes in parenting practices, which in turn would predict changes in exposure to violence (i.e., a mediational model). We found that participation in GREAT was significantly related to changes in parenting practices and these changes significantly predicted changes in violence exposure. Furthermore, adolescents who reported greater increases in exposure to violence also tended to experience greater decreases in parental monitoring, discipline, and involvement. Implications for future research and prevention efforts are discussed.  相似文献

Previous research on preference between variable-interval terminal links in concurrent chains has most often used variable-duration terminal links ending with a single reinforcer. By contrast, most research on resistance to change in multiple schedules has used constant-duration components that include variable numbers of reinforcers in each presentation. Grace and Nevin (1997) examined both preference and resistance in variable-duration components; here, preference and resistance were examined in constant-duration components. Reinforcer rates were varied across eight conditions, and a generalized-matching-law analysis showed that initial-link preference strongly over-matched terminal-link reinforcer ratios. In multiple schedules, baseline response rates were unaffected by reinforcer rates, but resistance to intercomponent food, to extinction, and to intercomponent food plus extinction was greater in the richer component. The between-component difference in resistance to change exhibited additive effects for the three resistance tests, and was systematically related to reinforcer ratios. However, resistance was less sensitive to reinforcer ratios than was preference. Resistance to intercomponent food and to intercomponent food plus extinction was more sensitive to reinforcer ratios in the present study than in Grace and Nevin (1997). Thus, relative to variable-duration components, constant-duration components increased the sensitivity of both preference and relative resistance, supporting the proposition that these are independent and convergent measures of the effects of a history of reinforcement.  相似文献

The purpose of this study was to investigate coming out to family and friends and their relationships to shame, internalized heterosexism, lesbian identity, and perceived social support in Chinese lesbians from 2 different cultural settings-Mainland China (N = 244) and Hong Kong (N = 234). Results of structural equation modeling showed that, in both samples, a sense of shame was related to internalized heterosexism and a devaluation of one's lesbian identity, which in turn was related to a decreased likelihood of coming out to others. Shame was also associated with a reduced perception of support from friends, which seemed in turn to exacerbate internalized heterosexism among lesbians. Family support was generally unrelated to outness, except for outness to friends in the Hong Kong sample. Results are discussed in relation to the cultural stigma attached to same-sex orientation and the cultural practice of shaming that parents use to socialize children.  相似文献

The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions.  相似文献

Reactions to moral transgressions are subject to influence at both the cultural and individual levels. Transgressions against an individual's rights or against social conventions of hierarchy may elicit different reactions in individualistic and collectivistic cultures. In the current study, affective and behavioural reactions to transgressions of autonomy (rights) and community (hierarchy) were examined in India and Britain. Results revealed that although reactions to autonomy transgressions are similar in India and Britain, Indian participants express more moral outrage than do Britons in response to transgressions of community. Results also supported the contention of emotion‐specificity in affective moral reaction: Participants in both India and Britain reported anger in response to autonomy transgressions, but contempt in response to violations of community. Importantly, these results extend previous research by demonstrating the importance of emotion specificity in moral reactions, as opposed to categorization or dilemma resolution. In addition, an individual difference measure of respect for persons was shown to moderate reactions to moral transgressions. Specifically, participants with high respect for persons were less negative to violators of the community ethic, but not the autonomy ethic. These findings highlight the importance of examining emotion‐specific responses in the moral domain and introduce a significant individual difference variable, respect for persons, into the psychology of morality.  相似文献

Participants with elevated anxiety sensitivity and a history of panic attacks were compared to a low anxiety comparison group with respect to physiological and subjective reactivity to false heart-rate feedback and reactivity to a priming procedure. Whereas accurate heart-rate feedback elicited minimal responses, participants across groups showed significant physiological and subjective responses to false feedback. High risk and low risk participants did not differ in heart-rate responses to false feedback, though panic attack frequency did predict physiological and subjective reactions to false feedback in the high risk group. Self-reported nonspecific anxiety was significantly higher in high risk female participants than in low risk female participants, while males did not different in general subjective anxiety. However, high risk participants reported more panic-specific symptoms during the false feedback task than low risk participants, regardless of the sex of the participant. Therefore, although the experimental paradigm appeared to trigger nonspecific anxiety in high risk female participants, panic attack symptoms in reaction to the task were specific to risk group, not sex, and consistent with hypotheses. Surprisingly, the priming procedure did not influence physiological or subjective responses to false feedback in either group. These results raise additional questions regarding the process and impact of interoception in individuals with panic attacks, and suggest that false perception of internal changes may contribute to risk for panic disorder when exposed to believable cues.  相似文献
