In this article, I examine A. John Simmons’s philosophical anarchism, and specifically, the problems that result from the combination of its three foundational principles: the strong correlativity of legitimacy rights and political obligations; the strict distinction between justified existence and legitimate authority; and the doctrine of personal consent, more precisely, its supporting assumptions about the natural freedom of individuals and the non-natural states into which individuals are born. As I argue, these assumptions, when combined with the strong correlativity and strict distinction theses, undermine Simmons’s claim, which is central to his philosophical anarchism, that a state may be justified in enforcing the law, even if illegitimate or unjustified in existing.  相似文献

Across all languages studied to date, audiovisual speech exhibits a consistent rhythmic structure. This rhythm is critical to speech perception. Some have suggested that the speech rhythm evolved de novo in humans. An alternative account--the one we explored here--is that the rhythm of speech evolved through the modification of rhythmic facial expressions. We tested this idea by investigating the structure and development of macaque monkey lipsmacks and found that their developmental trajectory is strikingly similar to the one that leads from human infant babbling to adult speech. Specifically, we show that: (1) younger monkeys produce slower, more variable mouth movements and as they get older, these movements become faster and less variable; and (2) this developmental pattern does not occur for another cyclical mouth movement--chewing. These patterns parallel human developmental patterns for speech and chewing. They suggest that, in both species, the two types of rhythmic mouth movements use different underlying neural circuits that develop in different ways. Ultimately, both lipsmacking and speech converge on a ~5 Hz rhythm that represents the frequency that characterizes the speech rhythm of human adults. We conclude that monkey lipsmacking and human speech share a homologous developmental mechanism, lending strong empirical support to the idea that the human speech rhythm evolved from the rhythmic facial expressions of our primate ancestors.  相似文献

ABSTRACT The purpose of this study was to measure the specificity of the 21-Item Test for detecting malingering in an elderly sample. The 21-Item Test was administered to 20 community-dwelling elderly individuals with means for age, education, and Short Portable Mental Status Questionnaire (SPMSQ) error scores of 76.25 years (SD?=?7.19), 14.30 years (SD?=?3.89), and 0.30 (SD?=?4.70). None of these healthy elderly participants were cognitively impaired. A second group of 53 nursing home residents had means for age, education, and SPMSQ error scores of 82.79 years (SD?=?8.56), 11.14 years (SD = 2.46), and 3.17 (SD?=?2.46). Approximately 60% of the nursing home participants had cognitive impairment based on the SPMSQ. The cut offs provided by Iverson (1998 , 21 Item Test Research Manual) for interpretation of the forced-choice component of the 21-Item Test were insensitive to age and relatively insensitive to cognitive deficits. Specificity was 100% since no elderly participant from either group scored in the range indicative of sub-optimal effort or biased responding.  相似文献

Pigs are a valuable animal model for studying neurodevelopment in humans due to similarities in brain structure and growth. The development and validation of behavioral tests to assess learning and memory in neonatal piglets are needed. The present study evaluated the capability of 2-week old piglets to acquire a novel place and direction learning spatial T-maze task. Validity of the task was assessed by the administration of scopolamine, an anti-cholinergic drug that acts on the hippocampus and other related structures, to impair spatial memory. During acquisition, piglets were trained to locate a milk reward in a constant place in space, as well as direction (east or west), in a plus-shaped maze using extra-maze visual cues. Following acquisition, reward location was reversed and piglets were re-tested to assess learning and working memory. The performance of control piglets in the maze improved over time (P < 0.0001), reaching performance criterion (80 % correct) on day 5 of acquisition. Correct choices decreased in the reversal phase (P < 0.0001), but improved over time. In a separate study, piglets were injected daily with either phosphate-buffered saline (PBS; control) or scopolamine prior to testing. Piglets administered scopolamine showed impaired performance in the maze compared to controls (P = 0.03), failing to reach performance criterion after 6 days of acquisition testing. Collectively, these data demonstrate that neonatal piglets can be tested in a spatial T-maze task to assess hippocampal-dependent learning and memory.  相似文献

Objectives

This study was designed to assess developmental outcomes underserved youth report from their sports participation; identify perceptions of the sports climate their coaches create; and, measure the relationships between participants reported gains and perceptions of the psychosocial sports climate.

Method

Participants were 239 urban youth sports participants from an underserved community who completed the Youth Experiences Scale (YES-2), Sport Motivational Climate Scale, Caring Climate Scale and measures of the importance their coaches placed on life skills.

Results

Multivariate analyses revealed a number of significant relationships between YES-2 outcomes and motivation and caring climate predictor variables, which clearly show that the more coaches create caring, mastery-oriented environments, the more likely positive developmental gains result.

Conclusion

These findings are consistent with the previous motivational (Smith, Smoll, & Cumming, 2007) and caring climate (Fry & Gano-Overway, 2010) research and shows that coaching actions and climates have an important influence on personal and social development of young people.  相似文献

Finding a job has become a critical challenge to many youth. Immigrant youth, who have been a key part of the global migrants, are particularly vulnerable when entering the job market of the host country due to various structural barriers. However, in both public policy discourse and research, their labour market experience tends to be overlooked. In this paper, we report the employment experience of recently arrived immigrant youth based on an analysis of the LSIC and findings of in-depth interviews of 82 immigrant youth in four cities in Canada. Our results reveal that recently arrived immigrant youth tend to work in lower-skilled employment, experience significant delays in finding employment, have difficulties with foreign credential recognition, and have fewer means to access to job markets.  相似文献

The current study examined the relation between perceiving a calling, living a calling, and job satisfaction among a diverse group of employed adults who completed an online survey (N = 201). Perceiving a calling and living a calling were positively correlated with career commitment, work meaning, and job satisfaction. Living a calling moderated the relations of perceiving a calling with career commitment and work meaning, such that these relations were more robust for those with a stronger sense they were living their calling. Additionally, a moderated, multiple mediator model was run to examine the mediating role of career commitment and work meaning in the relation of perceiving a calling and job satisfaction, while accounting for the moderating role of living a calling. Results indicated that work meaning and career commitment fully mediated the relation between perceiving a calling and job satisfaction. However, the indirect effects of work meaning and career commitment were only significant for individuals with high levels of living a calling, indicating the importance of living a calling in the link between perceiving a calling and job satisfaction. Implications for research and practice are discussed.  相似文献

Theistic and spiritually based beliefs and behaviors have been demonstrated to consistently predict physical and mental health, although the psychological processes underlying these relationships are unclear. This study investigated associative relationships and pathways of mediation between religious functioning, locus of control (LOC) and health. The sample consisted of 122 Christians (79 women, 43 men) who were predominately Catholic, ranging in age from 18 to 80 (M = 45.47, SD = 15.0). Participants were recruited from churches in the Western suburbs of Melbourne, Australia, and completed a questionnaire package measuring (1) psychological and physical health, (2) the religious variables of awareness of God, instability and impression management, and (3) God, internal and external LOC domains. Results indicated that awareness of God and internal LOC were associated with better health, whereas external LOC and instability were associated with poorer health. God LOC and impression management were not significantly associated with health. Sobel tests were used to analyse mediation hypotheses. Internal LOC was found to mediate the relationship between awareness of God and better psychological health, and external LOC was found to mediate the relationship between instability and poorer psychological health. These findings are of considerable clinical significance.  相似文献
