Most theories about virtue cultivation fall under the general umbrella of the role model approach, according to which virtue is acquired by emulating role models, and where those role models are usually conceived of as superior in some relevant respect to the learners. I argue that although we need role models to cultivate virtue, we also need good and close relationships with people who are not our superiors. The overemphasis on role models is misguided and misleading, and a good antidote draws on the Aristotelian concept of character friendship. Character friendship (a) constitutes a unique form of experience in which we share a substantial way of seeing with a close other; (b) facilitates a unique form of knowledge, the knowledge of a particular person (my‐self and the other's self); (c) develops other emotions important for virtue cultivation besides admiration, such as love, shame, trust, and hope; and (d) is a praxis in which cooperative interactions and discussions function as a bridge between habituation of virtue at home and the public life. Character friendship provides necessary elements for human cultivation of virtue that the sole experience of having a role model does not. 相似文献

In 2020, Australia's successful COVID-19 public health restrictions comprised a national “initial lockdown” (March–May) and “ongoing lockdown” (July–November) for metropolitan Victorian residents only. We evaluated associations between ongoing lockdown and family finances and mental health. In the June and September 2020 Royal Children's Hospital National Child Health Polls, caregivers of children in Victoria and New South Wales (NSW) reported the following: job/income loss; material deprivation (inability to pay for essential items); income poverty; mental health (Kessler-6); perceived impact on caregiver/child mental health; and caregiver/child coping. Data from caregivers (N = 1207/902) in June/September were analysed using difference-in-difference modelling (NSW provided the comparator). During Victoria's ongoing lockdown, job/income loss increased by 11% (95%CI: 3%–18%); Kessler-6 poor mental health by 6% (95%CI: −0.3%–12%) and perceived negative mental health impacts by 14% for caregivers (95%CI: 6%–23%) and 12% for children (95%CI: 4%–20%). Female (vs. male) caregivers, metropolitan (vs. regional/rural) families, and families with elementary school-aged children (vs. pre-/high-school) were the most affected. The ongoing lockdown was associated with negative experiences of mental health, employment and income, but not deprivation or poverty, likely because of government income supplements introduced early in the pandemic. Future lockdowns require planned responses to outbreaks and evidence-informed financial and mental health supports. 相似文献

Given the high prevalence of tuberculosis (TB) and the mortality rate associated with the disease, numerous models, such as the Gammaitoni and Nucci (GN) model, were developed to model the risk of transmission. These models typically rely on a quanta generation rate as a measurement of infectivity. Since the quanta generation rate cannot be measured directly, the unique contribution of this work is to develop state estimators to estimate the quanta generation rate from available measurements. To estimate the quanta generation rate, the GN model is adapted into an augmented single-room GN model and a simplified two-room GN model. Both models are shown to be observable, i.e., it is theoretically possible to estimate the quanta generation rate given available measurements. Kalman filters are used to estimate the quanta generation rate. First, a continuous-time extended Kalman filter is used for both adapted models using a simulation and measurement sampling rate of 60 s. Accurate quanta generate rate estimates are achieved in both cases. A more realistic scenario is also considered with a measurement sampling rate of one day. For these estimates, a hybrid extended Kalman filter (HEKF) is used. Accurate quanta generation rate estimates are achieved for the more realistic scenario. Future work could potentially use the HEKFs, the adapted models, and real-time measurements in a control system feedback loop to reduce the transmission of TB in confined spaces such as hospitals. 相似文献

How do low socioeconomic status students navigate cross-class interactions in extremely unequal contexts? Previous research has described the high costs of college integration for underprivileged students, which in turn, negatively impact academic performance and general wellbeing. These studies tend to concentrate on cultural capital costs, such as catching up with assumed middle-class or elite capital and dealing with two worlds. Less has been said about social capital costs, the costs of making friends, especially more privileged friends. Through 61 in-depth interviews with various types of students as part of a broader ethnographic fieldwork, this article analyses the experiences of low-income scholarship holders in an elite institution in a very unequal society, Colombia. Rather than isolating themselves or resorting to safe homophilic relations, they faced their new elite environment engaging with the hidden relational cost of making friends with more affluent students. In so doing, they had to overcome fears and experiences of discrimination and micro-aggressions, as well as cultural and economic capital barriers, and employed either camouflaging or disclosure strategies, sometimes becoming culturally and socially omnivorous. Symbolic belonging to the institution and the acquisition of middle-class cultural capital were among the benefits that made overcoming the costs worthy. Our results shed light on what institutions can do to reduce the costs for underprivileged students and, theoretically, unveil an important mechanism and barrier for social mobility: building cross-class ties. 相似文献

A variable-centered and a person-centered approach were performed to examine the role of early memories of warmth and safeness (EMWS) and current experiences of warmth and safeness (CEWS) on depressive and anxious symptoms among adolescents from community and residential youth care (RYC) settings. Variable-centered results revealed EMWS were only indirectly (through CEWS) associated with depressive and anxious symptoms. Person-centered outcomes allowed to identify four different profiles based on EMWS and CEWS, which differed on depressive and anxious symptoms. EMWS and CEWS seem to play an important role in psychological distress during adolescence. CEWS seem to have a protective role on RYC adolescents' psychological distress, even when EMWS were poor. 相似文献
