Over the last few years, the estimation of energy expenditure with accelerometers has become more and more accurate due to
improvements in sensor technology. Significant enhancement could be reached by model-based estimation regarding different
activity types. The kmsMove-sensor (movisens GmbH, Karlsruhe, Germany) is a device that is used to compute human energy expenditure
using motion-dependent calculation models. It is outfitted with an accelerometer to measure body acceleration during certain
movements and activities. To validate its accuracy, the sensor was compared to indirect calorimetry as criterion measure.
For this experiment, nine subjects (all males, age 46.4 ± 10.9 years, 28–64 years) were equipped with the kmsMove-sensor as
well as a portable indirect calorimeter and their energy consumption was measured over a time period of 100 min. Additionally,
the energy consumption of seven out of the above-mentioned nine subjects was measured over an average of 7 h. The measurements
took place in a rehabilitation clinic, where the subjects completed their regular daily rehabilitation activities. An analysis
of the data revealed ICCs between the kmsMove-sensor and indirect calorimetry for the time period of 100 min of 0.82 (0.38–0.96;
p = 0.003) and for an averaged measuring time of 7 h of 0.81 (0.22–0.97; p = 0.01). Furthermore, a Bland–Altman analysis for the time period of 100 min led to a difference of the means of 4.3 kcal
(limits of agreement: −94.3 and 102.9 kcal) and for the time period of an average of 7 h to −14.0 kcal (limits of agreement:
−320.0 and 292.0 kcal). These findings indicate that the kmsMove-sensor is an appropriate measuring device with relatively
good accuracy to assess human energy expenditure in rehabilitation patients. However, this study has some limiting aspects
(small sample size, artificial setting) which could influence validity. 相似文献

This paper explores the political relevance of the Landcare movement in Australia in an attempt to understand the capacity of rural people to develop political outcomes through social action in civil society. We relate Claus Offe's notion of a politically relevant new social movement to movement development in Landcare and discuss the implications of this in terms of movement stability, relationships with the state and neo-liberal governance in Australia.Landcare has many of the characteristics attributed to new social movements. People involved in Landcare typically express a commitment to participatory forms of action and coordination, believe in a ‘win-win’ approach to conflict and are opposed to government ‘telling them what to do’. Forms of limited protest and conflict with government occur when core values of autonomy and participation are perceived to be under threat and these values are perceived to be universal rather than just applying to movement participants. However, in contrast to the attributes associated with new social movements, Landcare does not have an outwardly ‘oppositional’ character and a high proportion of movement members in Landcare are farmers and close to the imperatives of agricultural commodity production. Further, the state has had a central role in the initiation and ongoing support of the ‘movement’.These two latter points of difference, however, confer the most ‘political relevance’ to the movement. The role of the state in catalysing Landcare and promoting the ‘program’ in terms of its participatory values, confers significant legitimacy on the outcomes of participatory Landcare fora. Further, the increased transparency and learning of the environment through Landcare activities by farmers can lead to a questioning of the current economic orthodoxy that underpins rural policy. 相似文献

Purpose: While previous research has well-examined the stress reducing effects of mindfulness, much less is known, evidentially, about the impact that it might have on working behavior, particularly in the context of leadership. Against this background, the goal of our study was to examine whether mindfulness influences leadership behavior.Design: To answer this question, we used a two-source survey study consisting of 60 teams, examining trait mindfulness of leaders via self-evaluation and their leadership behavior through the eyes of their subordinates. To analyze the given data, we conducted regression analyses.Results: Our findings confirmed the hypothesized relationships. We found a negative relationship between leaders’ mindfulness and destructive leadership, as well as a positive one between leaders’ mindfulness and transformational leadership.Implications: The results of our study underline the importance of mindfulness as a potential tool to optimize leadership quality. In order to prevent destructive and promote transformational leadership, organizations should help to develop leaders’ mindfulness capacities. 相似文献

The contribution analyzes from a sociological perspective the development of the blog, passing through the different typologies, to define the relationship that develops in today's society between the network and the individual, through a theoretical comparison of the major scholars who have dealt with the issue of network. From Sherry Turkle to Manuel Castells up to the studies of Barry Wellman, we will define the development of the network as a new social space. The work incorporates some classical theories of Simmel, some by Goffman and Thompson about interaction, of community-society by Töennies and the action-system of Luhmann. The central part of the article focuses on how the space of the network can become, in some cases, a ‘place’ of sharing not only of entertainment topics but also of those that have some importance for public opinion. Then the blog becomes a ‘showcase’ in which to expose the peculiar characteristics of one's identity, but also a point of listening for those who do not have easy access to traditional media. Through the testimony of two young people, we will highlight those aspects that characterize the blog as a communication tool, from the diary to the letter, as well as the role played by these documentary sources in the past in sociology's field. In this way, some salient points arise about the use of the network space, compared to traditional media. The last part of the contribution proposes a comparison between America and Japan about the use of blogs and social networks, no longer in numerical terms, but proposing a reflection that brings out an individual who, as a sociable being, exploits all the possible ways to communicate, feeling in such situations freer to express his emotions, and able build a dialogue that turns out to be an added value to his person and in relationship with others outside. 相似文献

The domestic home plays an important role in the process of socialization. In the context of migration, home becomes even more meaningful as a site for socialization, since it provides—next to the Internet, cultural events and places of religious worship—one of the few sites where young children can learn about their parent’s cultural and religious traditions in their new homelands. Grounded in data gathered through ethnographic fieldwork, this article seeks to gain a deeper understanding of the ways in which the domestic space of home is involved in the process through which young Sikhs who are growing up in Finland are made familiar with their parents’ religion. To reach this objective, I will examine home as a “cosmos of senses” that has been created by its inhabitants and the practices they perform in the course of everyday life. Applying the ethnographic lens in the study of the domestic home of Sikhs will also help us to gain a more profound understanding of Sikhism as a lived religion, as the findings presented in this article show. 相似文献

This paper explores temporal constituents of the female self in terms of their role in underpinning ongoing gender inequality. Drawing on the work of Simone de Beauvoir and Iris Marion Young, together with sociological approaches to ambivalence, I suggest that these temporal subjectivities are embodied, arise from the split subjectivity associated with woman as simultaneously subject and object, and counterpose the neoliberal emphasis on “choice” and agency with a more traditional gendered “expectation,” or “waiting” style. The dialectic between both temporalities, in which neither is hegemonic, results in a chronic state of ambivalence which impedes women's ability to fully project themselves into the future, a skill significant to planning and career ambition and the absence of which suspends women instead in an extended present. The paper aims to do two things in particular. In conceptual terms it aims to explore aspects of the configuration of the gendered self that underlie the stalling and slowing down of the gender revolution and which can be seen to provide a “missing link” between structures, institutions, and micro-cultures. In empirical terms, it suggests a future research agenda, of which this paper constitutes a beginning, through which such gendered temporalities can be explored in greater detail via ethnographies of women's lived experience of time throughout the life course. 相似文献

The majority of youth in the foster care system have been removed from their homes as means of protection against parental maltreatment. Studies have shown, however, that foster youth may continue to experience maltreatment after they have entered the child welfare system (Poertner et al. in Child Youth Serv Rev 21(7):549–563, 1999; Tittle et al. in Urbana 51:61801, 2008). In this study, we explore how maltreatment prior to foster care entry may predict maltreatment while in care for youth who are preparing to emancipate. Using latent class analysis and multinomial logistic regression, we find that current or former foster youth with histories of multiple maltreatment (particularly, combined pre-foster care histories of neglect and physical abuse) are more likely to report neglect, physical abuse and sexual abuse in care than those with histories of low maltreatment. These youth should be the target of prevention efforts in child welfare agencies. 相似文献

In this paper, we evaluate the Swedish self-employment start-up program based on a matching approach using data from administrative records. In addition to information of labor market history, traditional human capital and socio-economic variables, the data at hand also include information on the self-employment history of participants and nonparticipants as well as that of their parents. Our results indicate that the start-up subsidy program for unemployed persons is a successful program regarding the integration of the unemployed into the mainstream of the labor market. We find that, relative to members of control groups, participants, on average, have an increased probability of unsubsidized employment. Our analysis of different educational backgrounds presents the strongest employment effects for the low educated unemployed. 相似文献

The founding of the SSSS in 1957 was perhaps one portent of the sexual revolution of the sixties, which would break some of the power of the antisex forces. At the time, the Society had no competititon, whereas now there are various splinter groups. It would be better had sexologists kept united in the common cause of founding a new academic discipline of sexology. Meantime, there is no department of sexology in any medical school or teaching hospital in the Western hemisphere. Sexology, because human beings are a sexually dimorphic species, deals basically with a partnership, not an indivisual. It has four branches: experimental and investigative; clinical and therapeutic; education and training; and standards and certification. The SSSS and the JOSR can contribute to a more systematic and less laissez faire growth of sexology as an academic discipline. 相似文献

This review discusses the measurement, antecedents, and consequents of erotophobia‐erotophilia—the disposition to respond to sexual cues along a negative‐positive dimension of affect and evaluation. Test construction procedures which resulted in a 21‐item measure of this personality construct are reported. Evidence indicates that the measure is internally consistent, shows acceptable degrees of convergent and discriminant validity, and is correlated as expected with related constructs such as authoritarianism, adherence to traditional sex roles, indices of value orthodoxy, and various measures of sex‐related evaluations. Retrospective surveys and group contrasts suggest that erotophobia‐erotophilia is a learned disposition based on one's exposure to sex‐related restrictiveness and punishment during socialization. Consequents of erotophobia‐erotophilia involve avoidance versus approach responses to sexuality in a wide range of situations; scores on this test predict differential sexual experience, responses to erotica, likelihood of engaging in sexual fantasy behavior, the tendency to learn about or teach others about sex, engaging in sex‐related health care, the probability of utilizing contraception, and behaving sexually during pregnancy and postpartum. Cross‐cultural research provides evidence for the generality of this construct beyond North America. 相似文献

Israel has known a very high inflation rate and two currency changes in thepast five years. Coin size estimation by 97 subjects reveals a general tendency to underestimate sizes. The specific pattern of results suggests that coin size estimation is influenced by the subject's attitude towards the coin in question, that inflation and actual value of the coin are not the only determinants of that attitude, and that the attitude remains unchanged if the coin is removed from circulation. 相似文献

This paper addresses the phenomenon of “psychic numbing” in the clinician, which interfered with the clinician’s capacity to understand and respond to the patient’s highly turbulent reaction to a personal crisis of the clinician. Through gaining an understanding of the meanings of the retraumatizations for both the patient and the clinician, the clinician became able to recapture the functioning of her mind, respond differently to the patient, and thus facilitate the calming of the turbulence of the treatment. The clinician’s understanding included her recognition of her own thwarted twinship longings with the patient. 相似文献

The network concept has become widely utilised in socioeconomic studies of economic life. Following the debates around exogenous and endogenous development, networks may also have particular utility in understanding diverse forms of rural development. This paper assesses whether networks provide a new paradigm of rural development. It seeks to capture a series of differing perspectives on economic networks — including political economy, actor-network theory and theories of innovation and learning — and attempts to show how these perspectives might be applied to different types of rural areas. The paper demarcates two main “bundles” of networks: “vertical” networks — that is, networks that link rural spaces into the agro-food sector — and “horizontal” networks — that is, distributed network forms that link rural spaces into more general and non-agricultural processes of economic change. It is argued that rural development strategies must take heed of network forms in both domains and that rural policy should be recast in network terms. 相似文献

This article presents the major results of a survey on the profession in Spain. An international research program previously conducted in eight European countries (Denmark, Finland, France, Italy, Norway, Portugal, Sweden and the United Kingdom) was adapted to Spain. The sample was made up of Spanish professionals who were members of professional organizations in sexology. The questionnaire used in the other European countries was translated and adapted into Spanish; its 89 questions inquired into: the sociodemographic profile of respondents, their initial academic and professional background, the specific training received in sexology or human sexuality, and their professional practices in sexology. In Spain, most sexologists are women from a nonmedical health profession. Most respondents received specific training in sexology and stated that it is not necessary to be a physician to be a sexologist. The findings bring to light many similarities with the data collected in the eight other European countries. 相似文献

The purpose of this article is to determine whether known cardiac risk factors are more prevalent among women veterans who report having sustained sexual assault while in the military. We surveyed a random sample of 3,632 women veterans using Veterans Administration (VA) ambulatory care nationally. Obesity, smoking, problem alcohol use, sedentary lifestyle, and hysterectomy before age 40 were found to be more common in women reporting a history of sexual assault while in the military than in women without such history. An association between myocardial infarction and prior sexual assault history may be mediated in part by known cardiac risk factors. 相似文献
