Community responses to domestic violence typically involve the introduction of multiple interventions. Yet very little is known about the impact of the timing and sequencing of these interventions on community outcomes. A reason for this is the inherent limitations of traditional methods in social science. New methods are needed to understand the effect of varying the sequence and timing of interventions. This study responds to the issue by introducing system dynamics as a method for modeling community interventions. The paper presents a model of domestic violence cases moving through a criminal justice response, and uses the simulation model to evaluate the impact of implementing three interventions—mandatory arrest, victim advocacy, and changes in level of cooperation—on two system-level outcomes: improving offender accountability and increasing victim safety. Results illustrate the complex nature of these relationships. Implications for community practice and future research are also discussed.  相似文献

ABSTRACT— Many local and global environmental challenges are tragedies-of-the-commons dilemmas in which private and collective interests are frequently at odds. Recent developments in social psychological theory and research suggest that in such commons dilemmas people are not just motivated by narrow (economic) self-interest but that they also consider the broader implications of their decisions for others and for the natural environment. Based on a core-motives analysis, I identify four necessary components for designing interventions to protect the environment: (a) information, (b) identity, (c) institutions, and (d) incentives, and discuss their utility and the feasibility of incorporating them.  相似文献

ABSTRACT— Humans seem unique in their consideration of others' goals, motivations, intentions, and needs. But the human form of social awareness did not spring from nowhere; certain mechanisms shared across primates formed the foundation from which these processes derived. A review of recent nonhuman primate research points to particular ancestral mechanisms, including an interest in images moving in synchrony with self, a mirror neuron system that responds in the same way to actions made by the self and by others, and inherited social tolerance that provided the bases for social thinking. Still there is a gap in tracking social awareness from these basic beginnings to the ability to think about self and other with respect to intentions and goals. Comparative and clinical work will fill in this gap and will map brain processes onto social thinking.  相似文献

In his book Religion Is Not About God, Loyal Rue presents an evolutionarily based explanation of religion as a means to further the personal and social fulfillment of human beings. Rue argues that religions in the form of myths, adaptive falsities, provide an account of the connection between what is (facts) and what matters (values). Myths are false because they attribute subjectively based values to valueless facts, but adaptive because they motivate personally and socially beneficial actions. He maintains that the current crises of humankind, evidenced by both social conflict and environmental degradation, indicate that the major religious traditions—all of which project values onto some transcendent reality—are failing to serve humanity. To overcome these crises, Rue maintains that we need a new, scientifically based naturalized religion, one that attributes subjectively based values to Nature instead of a transcendent reality. I accept Rue's naturalism about values but reject his subjectivist account of them. Contrary to Rue, I show that the naturalistic fallacy sets no barrier to the existence of objective moral values. Modeling my view on the selection theories used in biology and psychology, I offer a scientifically based explanation of the origin and existence of objective values and support it with empirical findings from developmental psychology. Whether this account can count as religious, I do not address.  相似文献

Summary  In the biological realm, a complete explanation of a trait seems to include an explanation in terms of function. It is natural to ask of some trait, “What is its function?” or “What purpose in the organism does the particular trait serve?” or “What is the goal of its activity?” There are several views concerning the appropriate definition of function for biological matters. Two popular views of function with respect to living things are Cummins’ organizational account and the Griffiths/Godfrey-Smith modern history account. Whereas Cummins argues that a trait functions so as to contribute to the general organization of some organism’s present structure, Griffiths, and Godfrey-Smith argue that a trait functions because of its fitness with respect to the organism’s recent evolutionary history. In this paper, I show how these accounts can be made compatible and compliment one another. Given that structure, organization, operational flexibility, function, and evolutionary history are all factors to be considered in an organism’s makeup, we should expect that the traits of an organism function the way they do because such traits presently contribute to the overall organization of the organism (Cummins) as well as were selected for in the organism’s species’ recent ancestry (Griffiths/Godfrey-Smith).  相似文献

Languages are transmitted from person to person and generation to generation via a process of iterated learning: people learn a language from other people who once learned that language themselves. We analyze the consequences of iterated learning for learning algorithms based on the principles of Bayesian inference, assuming that learners compute a posterior distribution over languages by combining a prior (representing their inductive biases) with the evidence provided by linguistic data. We show that when learners sample languages from this posterior distribution, iterated learning converges to a distribution over languages that is determined entirely by the prior. Under these conditions, iterated learning is a form of Gibbs sampling, a widely-used Markov chain Monte Carlo algorithm. The consequences of iterated learning are more complicated when learners choose the language with maximum posterior probability, being affected by both the prior of the learners and the amount of information transmitted between generations. We show that in this case, iterated learning corresponds to another statistical inference algorithm, a variant of the expectation-maximization (EM) algorithm. These results clarify the role of iterated learning in explanations of linguistic universals and provide a formal connection between constraints on language acquisition and the languages that come to be spoken, suggesting that information transmitted via iterated learning will ultimately come to mirror the minds of the learners.  相似文献

股骨头坏死、髋关节脱位是骨科常见病,随着人们生活模式的改变发病率有所上升。对该病的成因、流行病学、病理转归、临床治疗策略与髋关节严重病损后功能重建等问题,学术界存在很大争议。作者提出从生物进化的角度、用自然重建理念做指导,应用髋关节分离牵拉术治疗股骨头坏死、骨盆补充截骨术重建青少年严重病损的髋关节功能人、组合性矫形手术治疗年长儿先天性髋关节脱位,获得了优良效果。因此呼吁:用自然重建理念治疗青少年股骨头坏死、髋关节脱位,降低人工假体置换对此类疾病的手术指证。  相似文献

“慎独”论来源于孔子及其儒门对《诗》之解读与阐发,然后由诗学话语转化为整个儒学的重要理论之一,即“慎独”儒学理论的形成经历了一个从无到有、从简单到复杂、从感性到理性、从诗学到哲学的渐次发展的过程,在这个“层累”递进的过程中,“慎独”被赋予了许多新的不同层次的内涵。  相似文献
