Quakers’ early relations with American Indians (especially the Lenne Lenape, later known as the Delaware Indians) were generally positive. Core Quaker principles were simplicity, integrity, equality and peace – principles that could coincide well with those of the similarly egalitarian Lenne Lenape, who had been designated peacekeepers by the Iroquois Confederacy. Although the relationship was different than that of other settlers and American Indians, it was still suffused with colonial ideology. From the founding of Pennsylvania to the period of Grant’s ‘Peace Policy’, Quakers had to negotiate two wars and changing attitudes to North American Indians by American Presidents and government. The paper focuses on corresponding shifts in Quaker attitudes and policies. Our interest is in Quaker responses to Native Americans over time, finding that Quakers became increasingly distanced from the Indians and focused on acculturation. In their zeal to become acceptable to American Governments and through that, assist Native Americans, Quakers had, in fact, assimilated themselves.  相似文献

Team-based working has become a popular model of work organization. One of the expected yields of working in teams is collective learning. As team members work closely together they are likely to exchange information, which can enhance learning. One of the processes that may facilitate team learning is team conflict. In this study, 471 respondents, working in 84 teams in 38 organizations, indicated their perceptions of task conflict, relationship conflict, team learning, and their rating of the performance of the team. Task conflict was not related to team learning but was negatively related to the team members' rating of team performance. As was hypothesized, relationship conflict negatively affected team learning. Importantly, team learning was a strong predictor of the perceived team performance and partially mediated the relation between relationship conflict and performance.  相似文献

Many studies have reported on the adverse effects of maternal depression on offspring. Infants of depressed mothers are found to be more likely at risk to develop mental and socioemotional problems. In this study, an early intervention program is presented that aims to improve the interaction between depressed mothers and their infants to prevent developmental problems in the children. The program has recently been introduced in the Dutch Community Mental Health Centers as part of a national multicomponent program to reduce the risk of psychiatric and social problems in the offspring of parents with a mental disorder. The intervention for depressed mothers with babies is based on a transactional model in which the mother–child interaction plays a key role in explaining the development of socioemotional problems in the children. The model as discussed in the first part of this article addresses a range of evidenced‐based parental, child, and contextual risk factors that effect the quality of the interactions between depressed mothers and their infants and that contribute to both vulnerability and resilience of the children during later childhood and adolescence. ©2005 Michigan Association for Infant Mental Health.  相似文献

Differences in speaking time during a group interaction are hypothesized to reflect differences in individual dominance. In order to test this assumption and to identify potential moderator variables influencing the strength of the predicted association, a meta‐analysis was conducted. Whether speaking time is used to convey dominance to the same extent that it is used in inferring dominance was tested by contrasting studies concerned with dominance expressed in speaking time with studies of inferred dominance based on speaking time. Overall, and for the investigated subcategories of studies, the relationship between dominance and speaking time was significant. The strength of the associations, however, differed considerably due to the influence of moderator variables. The results showed that inferred dominance studies showed stronger associations between speaking time and dominance as opposed to the expressed dominance studies. Additionally, if dominance was expressed due to dominance‐role assignments, the association between speaking time and dominance was stronger than if individuals with different levels of trait dominance interacted. For men, the association between speaking time and dominance was stronger than for women, and same‐gender groups showed stronger associations than opposite‐gender groups. Also, increasing group size intensified the strength of the association linearly.  相似文献

The movement advocating the formal certification of clinical ethics consultants may result in major changes to the field of clinical ethics consultation by creating a new standard of care. The actual certification process is still in the development phase, but unanswered questions include: What will certification cost, and, Who will pay? Currently there is little salary support for ethics consultants and no regulation requiring healthcare institutions to offer clinical ethics consultation. Without the support of healthcare administrators and accreditation bodies, this may remain unchanged. Healthcare administrators may be unwilling to pay for certification or professional services if accreditation bodies do not require healthcare institutions to provide certified ethics consultants' services. If consultants will not be reimbursed or paid, they may not seek certification. If certified consultants are required, healthcare administrators may look for ways to cover the costs for providing this service, including insurance or third-party reimbursement and direct billing of patients for consultations, which may affect who performs and who participates in ethics consultation. However, this is less than ideal, as bioethicists believe ethics consultation should be available to all as part of providing safe, quality ethical care and support and guidance for patients, families, and healthcare staff. Going forward, bioethicists should study quality improvement, patient safety, and cost-savings resulting from certification-eligible clinical ethics consultants' activities. Administrators and financial personnel can be surveyed regarding their support for the certification process. Bioethicists should enlist the help of patient rights and safety advocacy groups, professional medical associations, and healthcare administrators. Bioethicists should invite accreditation bodies, healthcare administrators, and financial personnel to collaborate in the development of the certification process. Without their support, certification may be of value only to the bioethics community, and may have little standing in actual clinical healthcare institution settings.  相似文献

Internal models are constantly updated based on the actions and experiences of a person in the world. In the present study, we proposed to assess the updating process of internal models of action by providing new environmental constraints for motor planning, postural control, and execution processes in daily tasks such as STS and BTS. STS and BTS tasks were performed with different inclinations of the support surface on which the participant and the chair were positioned: horizontal support, support tilted 10° to the right, or forward. Twelve healthy adults participated in this experiment. Kinematic characteristics were recorded using an optoelectronic motion analysis system. Movement duration and trunk inclination amplitudes were analyzed for STS and BTS as well as trunk orientation and strategies of head stabilization. Concerning the movement analysis our results showed (1) temporal asymmetry between STS and BTS, attributed mainly to the integration of the mechanical effects of gravity, and (2) a decrease of trunk movements when the support was tilted forward, attesting to an immediate adaptation process. Concerning the postural analysis our study revealed that adults adopted selective head stabilization on space strategy with respect to balance constraints. To conclude, young adults were able to immediately update their internal model of action in order to optimize motor control and vertical body orientation.  相似文献

Women typically outperform men on the ability to assess other people??s nonverbal behavior. This difference might occur because women are taught to be more sensitive to emotional and nonverbal cues at a very early age compared to men. As a consequence, women might use a more favorable cognitive processing style than men during nonverbal decoding. The present study investigated whether this gender difference is due to the use of different cognitive information processing styles (global or local). Participants (N?=?137) were Swiss undergraduate students that were randomly assigned to either a global (focusing on the whole) or a local (focusing on details) priming of information processing style, or to a control group. They then performed a nonverbal decoding task. Results showed that compared to the control group, local priming had beneficial and global priming detrimental effects for nonverbal decoding accuracy. This was due to an improved performance in men after the local priming; women??s performance was not significantly affected by the local priming. Global priming increased nonverbal decoding accuracy in men and decreased performance in women. We conclude that women already use the more beneficial local processing style by default and that men??s performance can be boosted when providing them a processing strategy.  相似文献

To identify aspects of parental burden associated with borderline personality disorder (BPD), an anonymous internet survey linked to BPD support websites was developed for parents to complete on their BPD offspring and unaffected siblings. The questions cover aspects of the child's life from pregnancy through young adulthood, and query about the impact of the child's BPD on six domains of the parent's life, including physical and emotional health, marriage, job, standard of living, social life, and career trajectory. Additionally, financial burden was assessed with questions pertaining to insurance and out-of pocket costs associated with the BPD disorder. BPD offspring were identified by meeting diagnostic criteria embedded within the survey and having been given a diagnosis of BPD by a professional at some point in their life. We report on 233 female offspring meeting strict criteria for BPD. Parents of daughters with BPD endorsed varying levels of impact on the six domains comprising burden with the largest impact on emotional health which was impacted in over 88% of the respondents. Over 50% of parents endorsed four or greater of the six burden items. Particular aspects of the offspring's BPD symptom profile correlated with intensity of parental burden included including problems in adolescence with acting out behavior (p < .000), property destruction (.003), delusional symptoms (.007), and hallucinatory symptoms (.008). A subgroup of respondents provided data on specific financial expenses. The average and median out-of-pocket expense was $60,087, and $10,000. Insurance costs totaled an average of $108,251 with a mean of $20,000. The average cost per year after diagnosis was $14,606 out-of-pocket and $45,573 billed to insurance. The median cost per year after diagnosis was $3,667 out-of-pocket, and $12,500 billed to insurance. After adjusting for household income, a female proband who had been raped incurred roughly $40,000 more in BPD-related costs, while a diagnosis of conduct disorder led to about $50,000 in additional costs. Parents of female offspring with BPD experience burden in multiple domains of their life and many have incurred substantial financial expense. Increasing awareness of co-morbid conditions in the BPD proband that significantly increase parental burden may be indicators for the provision of increased family support.  相似文献

The ability of recruiters and laypersons (students) to detect applicant personality traits and deception was studied. Participants viewed mock videotapes of target applicants answering interview questions. They subsequently judged the applicants' personality on the Big Five dimensions. Then, they viewed another videotape with other applicants presenting themselves either truthfully or not, and subsequently guessed which version was truthful. Personality judgments were compared with targets' self‐assessments and peer assessments to create an accuracy score. Both recruiters and students accurately detected applicants' global personality profile. Recruiters were better at this than students. However, students were better at judging the specific traits of openness, extraversion, and conscientiousness, whereas recruiters only accurately detected openness. Recruiters detected lies above chance whereas students did not.  相似文献

In recent years, several authors have argued that the desirability of novel technologies should be assessed early, when they are still emerging. Such an ethical assessment of emerging technologies is by definition focused on an elusive object. Usually promises, expectations, and visions of the technology are taken as a starting point. As Nordmann and Rip have pointed out in a recent article, however, ethicists should not take for granted the plausibility of such expectations and visions. In this paper, we explore how the quality of expectations on emerging technologies might be assessed when engaging in a reflection on the desirability of emerging technologies. We propose that an assessment of expectations’ plausibility should focus on statements on technological feasibility, societal usability, and desirability of the expected technology. Whereas the feasibility statement and, to a lesser extent, the usability statements are frequently quite futuristic, the claims on desirability, by contrast, often display a conservative stance towards the future. Assessing the quality of expectations and visions on behalf of emerging technologies requires, then, a careful and well-directed use of both skepticism and imagination. We conclude with a brief overview of the tools and methods ethicists could use to assess claims made on behalf of emerging technologies and improve the ethical reflection on them.  相似文献
