College students (= 928) from small, medium, and large institutions with either a modified or no honor code were presented with cheating scenarios and asked to rate how dishonest they perceived the behavior to be and the likelihood that they would report it. No main effects were found for institution size or type of honor code. Student–faculty ratio was not correlated with responses to the cheating scenarios. Students from modified honor code schools perceived more severe punishments for cheating and understood the reporting process better than students from non–honor code schools. Implications for modified honor code systems are discussed.  相似文献

Digital medicine is a medical treatment that combines technology with drug delivery. The promises of this combination are continuous and remote monitoring, better disease management, self-tracking, self-management of diseases, and improved treatment adherence. These devices pose ethical challenges for patients, providers, and the social practice of medicine. For patients, having both informed consent and a user agreement raises questions of understanding for autonomy and informed consent, therapeutic misconception, external influences on decision making, confidentiality and privacy, and device dependability. For providers, digital medicine changes the relationship where trust can be verified, clinicians can be monitored, expectations must be managed, and new liability risks may be assumed. Other ethical questions include direct third-party monitoring of health treatment, affordability, and planning for adverse events in the case of device malfunction. This article seeks to lay out the ethical landscape for the implementation of such devices in patient care.  相似文献

Although receptive priming has long been used as a way to examine lexical access in adults, few studies have applied this method to children and rarely in an auditory modality. We compared auditory associative priming in children and adults. A testing battery and a Lexical Decision (LD) task was administered to 42 adults and 27 children (8;1-10; 11 years-old) from Spain. They listened to Spanish word pairs (semantically related/unrelated word pairs and word-pseudoword pairs), and tone pairs. Then participants pressed one key for word pairs, and another for pairs with a word and a pseudoword. They also had to press the two keys alternatively for tone pairs as a basic auditory control. Both groups of participants, children and adults, exhibited semantic priming, with significantly faster Reaction Times (RTs) to semantically related word pairs than to unrelated pairs and to the two word-pseudoword sets. The priming effect was twice as large in the adults compared to children, and the children (not the adults) were significantly slower in their response to word-pseudoword pairs than to the unrelated word pairs. Moreover, accuracy was somewhat higher in adults than children for each word pair type, but especially in the word-pseudoword pairs. As expected, children were significantly slower than adults in the RTs for all stimulus types, and their RTs decreased significantly from 8 to 10 years of age and they also decreased in relation to some of their language abilities development (e.g., relative clauses comprehension). In both age groups, the Reaction Time average for tone pairs was lower than for speech pairs, but only all adults obtained 100% accuracy (which was slightly lower in children). Auditory processing and semantic networks are still developing in 8-10 year old children.  相似文献

The use of maladaptive coping strategies following traumatic brain injury (TBI) is known to be associated with increased depression and a lower productivity status. What is not known is whether coping behaviours change following TBI and if they do change whether these changes account for significant variance in outcome. Seventy-three significant others of TBI survivors were recruited at the time their friend/family member was injured and followed prospectively. They reported on their friend/family member's pre-injury and 6-month coping behaviours using the Coping with Health Injuries and Problems Scale. The use of emotional pre-occupation coping (p = .02) increased significantly and approached significance for distraction coping(p = .08). These changes in coping also accounted for significant variance (22%, p = .02) in productivity status over and above that accounted for by demographics and injury severity. Whether maladaptive coping changes can be prevented with a view to improving outcomes is a question that now needs to be explored.  相似文献

The current study was conducted to ascertain the validity of two commonly used markers of acculturation (nativity and years in the receiving culture) in an enclave context. Relationships between these markers and a bidimensional measure of acculturation were examined in a convenience sample of Hispanic immigrant adolescents and their caregivers in Miami. Nativity was examined using adolescent-reported data; approximately half of the youth were U.S.-born and half foreign-born, but all of the caregivers were foreign-born. Years in the receiving culture was examined using both adolescent and caregiver data. Results indicated that nativity was significantly associated with adoption of receiving-culture practices, with a small to moderate effect size. Years in the receiving culture was significantly associated with adoption of receiving-culture practices only for adolescent girls and for female caregivers who immigrated as youth. Neither nativity nor years in the receiving culture explained even moderate amounts of variance in retention or loss of culture-of-origin practices.  相似文献

Ten adult male stutterers and ten adult male nonstutterers participated in six reaction-time tasks designed to measure manual, acoustic, and laryngeal-region response latencies. The analysis revealed statistically significant differences between the groups for the acoustic data only. The results indicated that acoustic reaction-time differences are not accounted for by the speed of the general laryngeal response.  相似文献
