In matters of discontinuation of life-sustaining treatment, traditional role of the family to speak on behalf of the incompetent patient is questionable. We explore the reasons why physicians perceive patient autonomy to be transferrable to family members. Principle of patient autonomy may not suffice when futile treatment is demanded and may serve to erode the ethical integrity of medical profession. An enhanced role for bioethics committees is proposed when physicians propose to discontinue life-sustaining treatment against the wishes of the patient or their families. 相似文献

Daily worldwide newspapers print articles exposing government corruption. Yet these messages do not lead to a loss of votes for the corrupt parties. Sympathizers’ partisan bias, which respectively minimizes and maximizes corruption and positive messages of their own parties respectively, is widely considered the main cause of the loss of effectiveness of political communications. Despite the well-established existence of such bias when processing political information, little is known as to its psychological origin. Through the use of neuroscience (fMRI), this study explores the underlying brain mechanisms of negative (corruption) and positive political messages related to a conservative and a socialist Spanish political party, as well as the differences between their sympathizers. The findings reveal that negative (vs. positive) political messages exert the greatest neuroimaging impact on the electorate, as shown in aversive, risk, and disappointment-related brain regions. Interestingly, we show that there exists a main partisan bias against opposite parties (and not a positive bias toward one’s own party) that stems from a higher risk, ambiguity, and disbelief provoked by both positive and negative information about rival parties. Furthermore, this bias was more pronounced among conservative supporters. The current findings provide valuable insights for political parties to improve their communication campaigns. 相似文献

This study investigated the impact of acculturative stress on psychological well-being and body image disturbance in a sample of female and male Hispanic individuals. The unique protective effects of differing social support sources, including family and peer support, were examined against acculturative stress and body image disturbance. A total of 399 participants of Hispanic origin were recruited from Texas Tech University in West Texas. Students completed a battery of measures of acculturative stress and internalization of the thin ideal, as well as perceived social support. Hierarchical regression analyses indicated that acculturative stress is a significant positive predictor of body image disturbance among Hispanic college students. Thin ideal internalization was found to mediate this relationship such that acculturative stress was associated with heightened body image disturbance through its impact on thin ideal internalization. Social support significantly reduced acculturative stress as well as body image disturbance but did not moderate the relation between these 2 factors. Results highlight the importance of considering acculturative stress as a strong predictor of body image disturbance among college students of Hispanic origin. The mechanisms of influence of acculturative stress on body image disturbance are discussed in relation to thin ideal internalization. The protective role of social support on these negative psychological outcomes is also clarified. This study is the first to examine these issues in a sample of female and male Hispanic college students and provides avenues for clinical interventions and future trials with diverse populations. 相似文献

Response monitoring abnormalities have been reported in chronic schizophrenia patients, but it is unknown whether they predate the onset of psychosis, are present in early stages of illness, or are late-developing abnormalities associated with illness progression. Response-synchronized event-related potentials (ERP) recorded during a picture-word matching task yielded error-related negativity (ERN), correct-response negativity (CRN), and error positivity (Pe) from 84 schizophrenia patients (SZ), 48 clinical high risk patients (CHR), and their age-matched healthy controls (HC; n = 110 and 88, respectively). A sub-sample of 35 early illness schizophrenia patients (ESZ) was compared to 93 age-matched HC and the CHR patients (after statistically removing the effects of normal aging). Relative to HC, 1) SZ, ESZ, and CHR had smaller ERNs, and 2) SZ and ESZ had larger CRNs and smaller Pes. Within the SZ, longer illness duration was associated with larger CRNs but was unrelated to ERN or Pe. CHR and ESZ did not differ on ERN or CRN, although Pe was smaller in ESZ than CHR. These results indicate that while ERN, CRN, and Pe abnormalities are present early in the illness, only the ERN abnormality is evident prior to psychosis onset, and only the CRN abnormality appears to worsen progressively over the illness course. Brain regions subserving response monitoring may be compromised early in the illness and possibly during its clinical prodrome. 相似文献

In settings in developing countries, children often socialize with multiple socializing agents (peers, siblings, neighbors)
apart from their parents, and thus, a measurement of a child’s social interactions should be expanded beyond parental interactions.
Since the environment plays a role in shaping a child’s development, the measurement of child-socializing agents’ interactions
is important. We developed and used a computerized observational softwareBehavior and Social Interaction Software (BASIS) with a preloaded coding scheme installed on a handheld Palm device to record complex observations of interactions
between children and socializing agents. Using BASIS, social interaction assessments were conducted on 573 preschool children
for 1 h in their natural settings. Multiple screens with a set of choices in each screen were designed that included the child’s
location, broad activity, state, and interactions with child-socializing agents. Data were downloaded onto a computer and
systematically analyzed. BASIS, installed on Palm OS (M-125), enabled the recording of the complex interactions of child-socializing
agents that could not be recorded with manual forms. Thus, this tool provides an innovative and relatively accurate method
for the systematic recording of social interactions in an unrestricted environment. 相似文献

Corporate Sponsorships of Philanthropic Activities: When Do They Impact Perception of Sponsor Brand?
We examined the benefits to a corporate sponsor of two types of philanthropic activities — cause promotions and advocacy advertising. Results from 4 laboratory studies indicate that perceptions of corporate social responsibility (CSR) are affected by consumers’ elaboration levels. Consumer perceptions of CSR are more favorable for cause promotions, which do not receive much elaboration, than they are for advocacy advertising, which prompts more elaboration. In addition, perceived congruence between the sponsor and the social issue is shown to moderate these effects: Higher congruence between the sponsor and social issue increases favorable ratings of CSR for cause promotions but only if elaboration on the sponsorship activity is facilitated. On the other hand, lower congruence increases favorable ratings of CSR for advocacy advertising as long as elaboration on the sponsorship is not constrained. We also found that higher congruence enhances CSR ratings if participants are primed to focus their attention on the sponsor brand, whereas lower congruence enhances CSR if participants are primed to focus their attention on the social issue. 相似文献
