The “raspberry task” represents a precision grip task that requires continuous adjustment of grip and pull forces. During this task subjects grip a specialized grip rod and have to increase the pull force linearly while the rod is locked. The aim of this study was to determine whether an associated, initially neutral cue is able to evoke pull-force changes in the raspberry task. A standard delay paradigm was used to study cued pull-force changes during an ongoing movement resulting in unloading. Pull force and EMG activity of hand and arm muscles were recorded from 13 healthy, young subjects. The cue was associated with a complex change in motor behavior.In this task, cued force changes take place more rapidly than in protective reflex systems (in median after the second presentation of the cueing stimulus). A cued force change was detectable in two-thirds of paired trials. Although the force change is produced by a decrease of the EMG activity in several grip- and pull-force-producing muscles, the most significant effect in the majority of the subjects was an increase of the activity of the flexor carpi ulnaris muscle which antagonises corresponding pull-force-producing muscles. Cued force changes require adequately and precisely controlled activation of the muscle groups involved in the movement. 相似文献

This paper is a systematic review of 39 empirical studies on family routines and rituals in the context of a chronic condition of a family member. The search strategy encompassed a wide spectrum of chronic conditions affecting family members from childhood/adolescence to adulthood. Twenty quantitative, 13 qualitative, 3 mixed‐methods, and 3 intervention studies published between 1995 and 2012 were reviewed. A conceptual framework of routines and rituals as key elements of family health was adopted, resulting in three main findings. First, a chronic condition in a family member impacted the frequency and nature of family's routines and rituals. Second, these whole‐family interactions held important functions for individuals and families, constituting strategic resources in the condition's management and opportunities for emotional support exchanges, and providing the family with a sense of normalcy amid the challenges posed by chronic conditions. Third, family routines and rituals were linked to positive health and adaptation outcomes for both patients and family members. Implications for future research include the need for the distinction between routines and rituals against a conceptual background, use of validated assessment methods, and empirical examination of predictors of changes in routines and rituals throughout the course of the condition and of the mechanisms linking these family events to positive outcomes. Conclusions support the inclusion of routines and rituals in a family‐centered care approach to the understanding and treatment of chronic conditions. 相似文献

Multiple losses can be associated with both infertility and child sexual abuse. This work seeks to explore the ways in which such connections can affect a survivor who subsequently experiences infertility and who may choose to pursue medical treatment. The potential consequences of such mirroring are explored from the perspective of counselling practice under the provisions of the Human Fertilisation and Embryology Act (1990). 相似文献

Based on Heinrich von Kleist’s drama Penthesilea and a clinical case, this study seeks to demonstrate a theoretical concept that is developed and identified as the anti‐oedipal condition. This state involves a regressive insistence on suffocating any form of oedipal maturation and, with it, any form of genital–sexual desire; it damages, even destroys, any form of intellectual–creative curiosity. A specific form of defensive organization, the anti‐oedipal condition, is sought out when psychic development, when oedipal–genital maturation requires re‐establishing contact with a sort of inner terra cremata, an emotional domain that once had been supposed to be eliminated due to catastrophic experiences that could not be integrated. This defensive organization dominated Kleist’s Amazons as well as Miss M. What happened first in both instances was a regression to and fixation at the anti‐oedipal condition, but the paths leading out of this incapsulation were antipodal. 相似文献

It is well known that we utilize internalized representations (or schemas) to direct our eyes when exploring visual stimuli. Interestingly, our schemas for human faces are known to reflect systematic differences that are consistent with one's level of racial prejudice. However, whether one's level or type of racial prejudice can differentially regulate how we visually explore faces that are the target of prejudice is currently unknown. Here, White participants varying in their level of implicit or explicit prejudice viewed Black faces and White faces (with the latter serving as a control) while having their gaze behaviour recorded with an eye-tracker. The results show that, regardless of prejudice type (i.e., implicit or explicit), participants high in racial prejudice examine faces differently than those low in racial prejudice. Specifically, individuals high in explicit racial prejudice were more likely to fixate on the mouth region of Black faces when compared to individuals low in explicit prejudice, and exhibited less consistency in their scanning of faces irrespective of race. On the other hand, individuals high in implicit racial prejudice tended to focus on the region between the eyes, regardless of face race. It therefore seems that racial prejudice guides target-race specific patterns of looking behaviour, and may also contribute to general patterns of looking behaviour when visually exploring human faces. 相似文献

ABSTRACTHuman microbial communities are bodies of microorganisms that reside in or on different body parts. Importantly, they have been found to affect human health. However, scientific research on human microbial communities has created new challenges for human subject recruitment. First, individuals are asked to collect samples of bodily substances that can be seen as repulsive (e.g. feces and urine). Second, because scientists want to understand how human microbial communities evolve over time, individuals are asked to commit to a regular sample collection for extended periods of time. A longitudinal qualitative study of the work of scientists, physicians, research staff, and study coordinators involved in a human microbiome research project has found that these actors can bypass some aspects of these recruitment and retention challenges through ‘tuning work’. Tuning work is a collaborative process where professionals agree to adjust their practices towards shared goals. Such professionals reconfigure their work practices, personal routines, and the study protocol in an effort to obviate cultural taboos against handling bodily substances. The burden of long-term participation provides fewer opportunities for tuning work for these professionals, however. As such, long-term commitment by human subjects remains a recruitment and retention obstacle. 相似文献

This article describes the Summer Institute in Global Mental Health and Psychosocial Support, a brief immersion training program for mental health, health, and allied professionals who work with populations that have endured severe adversities and trauma, such as domestic and political violence, extreme poverty, armed conflict, epidemics, and natural disasters. The course taught participants to apply collaborative and contextually sensitive approaches to enhance social connectedness and resilience in families, communities, and organizations. This article presents core training principles and vignettes which illustrate how those engaging in such interventions must: (1) work in the context of a strong and supportive organization; (2) appreciate the complexity of the systems with which they are engaging; and (3) be open to the possibilities for healing and transformation. The program utilized a combination of didactic presentations, hands‐on interactive exercises, case studies, and experiential approaches to organizational team building and staff stress management. 相似文献

This study tested a family‐based human immunodeficiency virus (HIV)/sexually transmitted infection (STI) prevention approach integrated within an empirically supported treatment for drug‐involved young offenders, Multidimensional Family Therapy (MDFT). A randomized, controlled, two‐site community‐based trial was conducted with 154 youth and their parents. Drug‐involved adolescents were recruited in detention, randomly assigned to either MDFT or Enhanced Services as Usual (ESAU), and assessed at intake, 3, 6, 9, 18, 24, 36, and 42‐month follow‐ups. Youth in both conditions received structured HIV/STI prevention in detention and those in MDFT also received family‐based HIV/STI prevention as part of ongoing treatment following detention release. Youth in both conditions and sites significantly reduced rates of unprotected sex acts and STI incidence from intake to 9 months. They remained below baseline levels of STI incidence (10%) over the 42‐month follow‐up period. At Site A, adolescents who were sexually active at intake and received MDFT showed greater reduction in overall frequency of sexual acts and number of unprotected sexual acts than youth in ESAU between intake and 9‐month follow‐ups. These intervention differences were evident through the 42‐month follow‐up. Intervention effects were not found for STI incidence or unprotected sex acts at Site B. Intensive group‐based and family intervention in detention and following release may reduce sexual risk among substance‐involved young offenders, and a family‐based approach may enhance effects among those at highest risk. Site differences in intervention effects, study limitations, clinical implications, and future research directions are discussed. 相似文献

This article focuses on political human rights and on the empirically assessed legitimation of these rights. This research considers the rights of refugees, the active and passive right to vote, and the right of protest. Given that the research is empirical research, respondents are requested to express agreement, disagreement or neutrality. The assumption is that contextual factors influence people’s assessment of rights. One contextual factor is, firstly, the concept of human dignity. International human rights covenants regard human dignity as the very foundation of all rights. That said, the concept of human dignity is subject to different understandings and – certainly in the past – the understanding of what constitutes human dignity has varied. Dignity can be related to the appreciation of the person given by others, to the moral behaviour of a person, and it can be understood as inherently related to the individual as a human being. It is this last understanding that forms the basis of modern declarations of human rights. Furthermore, the respondents’ value orientations and religious beliefs, along with society’s socio-political perception, will be examined to ascertain whether these factors have any influence on respondents’ attitudes towards political rights. The key question is: does human dignity influence people’s view of the legitimacy of political rights and do other factors also count? The empirical analysis was undertaken done with German youth (N=2244). Findings show that the concept of inherent human dignity is a strong predictor for respondents’ attitudes towards political rights, but that it is not the unique predictor; relevant concepts are the value orientation of youth and their socio-political orientation. The significance of religious beliefs as a predictor is low. 相似文献

The arrival of the electric vehicle (EV) on the market is one consequence of government measures to improve air quality and reduce CO2 emissions. However, the EV has specific properties of use associated with its limited range and relative silence compared to normal vehicles, influencing the mobility behaviours of drivers and requiring them to develop some new driving abilities. This paper examines the behavioural modifications brought about by daily use of an electric vehicle at three different levels of driving activity: strategic, tactical and operational. The study collected and analyzed the self-reported behaviours (via questionnaires and travels dairies) of 36 Parisian private drivers, each of whom drove for six months an electric MINI E prototype. The results of the study show that driving an EV requires a learning phase to acquire the skills and knowledge necessary to operate the vehicle. At the strategic level of driving, drivers take into account the restricted range of the EV, implement a daily charge process, and develop new behaviours related to trip planning. The study also examines driver behaviour at the tactical level, in terms of driver interactions with other road users to deal with the silent nature of the EV, and at the operational level of driving, in terms of braking behaviour to master the regenerative braking function of the EV. The paper discusses the interactions between these three levels of driving activity. 相似文献
