The reported birth of genetically modified twins in late 2018 has given new fuel to debates about the ethics of germline genome editing (GGE). There is a broad consensus among stakeholders that clinical uses of GGE should be temporarily banned as the technology is not yet deemed safe for use in humans. However, the idea of a complete ban is dismissed by many based on the expectation that more research will eventually allow scientists to make the technology safe without having to put humans at risk first. In this article, I will analyse this assumption and argue that it is undermined by recent developments in the postgenomic life sciences. In particular, I will argue that in a postgenomic view of germline editing a complete ban on specific uses of the technology is warranted, because the research needed to assess the safety of these interventions would not be morally defensible. 相似文献

This introduction to the special issue outlines key issues in research on inclusion—as the process of recognizing an individual’s needs for both belonging and distinctiveness. Whereas past research often focuses on diversity in relation to discrimination, this special issue attempts to offer a positive lens and asks how we can build inclusive societies. The answers range from emphasizing similarities based on multiple group memberships (intersectionality); creating inclusive workplaces by nurturing leadership that is authentic, respectful, creating belonging and valuing individuals’ unique contributions (ideas, skills, etc.); to developing bridging social capital as a means of cultural integration (vs. separation). The methodological approaches employed by the contributions in this special issue include an experimental vignette study, comparative studies of different ethnicities within a country and cross-culturally comparative work spanning multiple countries. The special issue is dedicated to the memory of Fons van de Vijver, who had initiated the special issue and sadly died last year. 相似文献

A series of studies examine the maintenance of the relative phase of simultaneous cyclic limb movements by the manipulation of the planes of motion during isofrequency and multifrequency conditions. To evaluate predictions from a dynamic pattern approach in which differences in the limbs' uncoupled frequencies give way to competitive interactions when the limbs are moved simultaneously, Experiment 1 determined the preferred frequencies of single-limb movements during sagittal and transverse planes of motions. The results revealed that the plane in which the motion was produced significantly affected the cycle frequencies. In investigating isofrequency coordination, Experiment 2 showed that homologous limbs were more accurate in attaining the relative phasing when moving in one as compared to two separate planes, whereas no such effect was observed for non-homologous limbs. Furthermore, the planes of motion significantly influenced the variability of relative phasing such thattwo-plane motionswere less stable than one-plane motions.Experiment 3 examined the effect of the planes of motion upon multifrequency coordination and demonstrated that the homologous and homolateral limbs were less successful in producing the relative phasing when the motions were produced in one as compared to two planes, whereas this effect was not observed for the heterolateral limbs. These findings indicate that frequency detuning resulting from the planes manipulation affects the quality of phase-locking during isofrequency and multifrequency conditions, even though it may be assumed that additional neural constraints are involved in the interlimb coordination process. 相似文献

This article introduces the concept of ‘counterproductive sustainability behaviors’ (CSB) as a novel expression of counterproductive work behaviors (CWB). It presents a short measure of CSB that applies the construct of counterproductivity to employee behaviors in the environmental sustainability domain. Personality assessments were administered to three independent samples—employed students, experienced employees, and job applicants—to investigate the relationship between personality and CSB (self-reports and other-rated), and to compare results to those obtained in the prediction of traditional CWB. 相似文献

According to Damasio’s somatic marker hypothesis, emotions are generated by conveying the current state of the body to the brain through interoceptive and proprioceptive afferent input. The resulting brain activation patterns represent unconscious emotions and correlate with subjective feelings. This proposition implies a corollary that the deliberate control of motor behavior could regulate feelings. We tested this possibility, hypothesizing that engaging in movements associated with a certain emotion would enhance that emotion and/or the corresponding valence. Furthermore, because motor imagery and observation are thought to activate the same mirror-neuron network engaged during motor execution, they might also activate the same emotional processing circuits, leading to similar emotional effects. Therefore, we measured the effects of motor execution, motor imagery and observation of whole-body dynamic expressions of emotions (happiness, sadness, fear) on affective state. All three tasks enhanced the corresponding affective state, indicating their potential to regulate emotions. 相似文献

Information changes as it is passed from person to person, with this process of cultural transmission allowing the minds of individuals to shape the information that they transmit. We present mathematical models of cultural transmission which predict that the amount of information passed from person to person should affect the rate at which that information changes. We tested this prediction using a function‐learning task, in which people learn a functional relationship between two variables by observing the values of those variables. We varied the total number of observations and the number of those observations that take unique values. We found an effect of the number of observations, with functions transmitted using fewer observations changing form more quickly. We did not find an effect of the number of unique observations, suggesting that noise in perception or memory may have affected learning. 相似文献

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions–PA relationship among older adults. Participants (N?=?143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception–behaviour relationship. 相似文献
