Food and water intake as functions of resource consumption costs in a closed economy.

In two experiments, rats living in a closed economy were offered continuous, concurrent access to four resources: food, water, a nest, and a running wheel. Costs of consuming food and water were imposed with bar-press requirements, and the price of either one or both resources was raised. As the consumption cost increased, less was consumed in each bout of resource use. Bout frequency increased, but not sufficiently to compensate for the fall in bout size, and total intake fell. Food and water tended to be complementary resources, in that as intake of one fell with its price, intake of the other also decreased. This interaction was accounted for by the defense of the ratio of body water to lean body mass. As amount consumed decreased, increases in feed efficiency (weight gain per unit of food ingested) and the use of stored calories compensated for the reduced energy intake. There was evidence of competition between feeding and drinking at the higher costs: When both commodities were expensive, the decline in the intake of each one was greater than when only one commodity was expensive. Although the time spent nesting, running, and in unmonitored activity was adjusted when feeding or drinking took more of the rat's day, there was no particular activity that was sacrificed.     

Shifting the focus from what to why

After 4 decades of research on infant behavior and development, the time has come to shift our focus from What infants do to Why they do it when they do—to move beyond the single-minded search for mechanism and to consider the larger question of function. Infants are not merely incomplete adults who simply get better with age, but they are different organisms altogether, perfectly adapted at every point in ontogeny. For this reason, answers to the Why question will necessarily build upon an evolutionary framework that reflects the infant's changing “occupations” or ecological niches. Through this pursuit, infancy researchers will develop a more integrative science and a greater sense of community.     

Living alone,marital status,gender and health

Non-married people have generally been found to be less healthy than the married. It has been suggested that this difference may be brought about by the greater lack of social integration of those living alone. This hypothesis was tested by comparing the health of those living alone with those living with another person in the four non-married categories of never married, separated, divorced and widowed for women and men separately, initially controlling for age, education and income and subsequently adding five proximate indices of social integration. The person lived with was further categorized as an adult, cohabitee, child aged 4 or under, child aged 5 to 17, adult child, parent, relative or non-relative. The three indices of health were the 30-item General Health Questionnaire of psychological distress. a 15-item checklist of common physical symptoms and alcohol intake. The main differences obtained were that women living alone drank more alcohol than those cohabiting or living with a child aged 4 or under, and that widowers living alone were more psychologically distressed than those living with an adult child, even when social integration was controlled. The results suggested that living alone was not generally associated with poor health and so could not account for the difference between the married and non-married.     

Effects of television modeling on residential energy conservation

A combination of social marketing, communications, social learning (particularly modeling), and behavior analysis may provide an effective framework for behavior change via films and television. We used this approach in developing special television programs about residential energy conservation. The programs were tailored and directed to preselected middle-class homeowners (N = 150), and delivered over a public access channel of a cable TV system. The results indicated that after one program exposure (about 20 minutes), viewers adopted simple strategies modeled in the programs which led to savings of approximately 10% on their home energy use for a substantial part of the cooling and heating season. Although the potential benefits to costs of large-scale media efforts seemed great, institutional barriers for such programs were identified. Less expensive, more local programs seem more viable.     

A practitioner's notes on the free-associative method as existential praxis

Freud's pre-1914 texts demonstrate why he consistently asserted that his free-associative method was the sine qua non of his discipline. Prior to 1914, Freud's theorizing was intimately and inextricably connected to his lived experience with the discovery of this method. After 1914, he became more speculative in this thinking and writing; his models of the “mental apparatus” and its functioning drew increasingly on conceptual sources other than his experience with free association. The four fundamental coordinates of his discipline (the methodical disclosure that self-consciousness is repressive, the nonlinear “time of the mind,” the significance of our sensual embodiment or libidinality, and the formation of the repression barrier by the incest taboo) are all closely tied to free-associative experience. By contrast, post-1914 theoretical preoccupations (from object relations to the structural-functional model, and other formulations generated after Freud's life) are comparatively divorced from such experience. These conceptual edifices imply a conventional depiction of the theory–practice relationship, which is radically challenged by free-associative discourse. The notion of praxis is introduced as contesting the prevailing depiction of practice as an application of theory, and as serving to rescue psychoanalysis from the somewhat “sterile debates” over its scientific status and over the relevance of metapsychological speculation to clinical treatment. Against the normative ideology of theory and practice, the lived experience of free-associative discourse, with its potential for change and healing, can only be understood in terms of this notion of praxis, and this justifies Freud's claim to have initiated “a critical new direction in science.”     

时间知觉的脑机制:时钟模型的困境和新导向

长期以来人们认为神经系统是通过类似于时钟的方式来实现对一段时间的知觉的,并认为多巴胺能系统(基地神经节)和时钟的快慢有关。与多巴胺信号有关的药物的动物实验的结果以及帕金森氏症(parkinson’s disease)患者的行为表现被看作是支持以上看法的证据。然而,最近的大量研究对这个理论提出了挑战,结合行为研究和脑机制研究的新成果,研究者提出了知觉信息可以通过神经活动状态或加工中的能量消耗来表达。     

“Working with Couples: Satir and the Tao,”

SUMMARY

One of Virginia Satir's greatest gifts to the world was the use of herself as an instrument of healing. By daring to use all of her-self-body, mind and spirit-the connections Virginia made with others were warm and real. Besides being authentically caring, Satir worked out of a pluralistic and comprehensive theoretical base to individualize each intervention. By co-creating strong, trusting relationships she inspirited others with her own life-force energy, and enabled them to become more fully human. Able to put her own ego needs aside, Virginia modeled how to join common sense with a sense of high purpose.     

Positive fantasies or negative contrasts: The effect of media body ideals on restrained eaters’ mood,weight satisfaction,and food intake

Although viewing media body ideals promotes body dissatisfaction and problematic eating among women (e.g., extreme restraint/overeating), some argue that women only report such negative effects because they think that they are meant to (i.e., demand characteristics). Because restrained eaters are trying to lose weight, they might be vulnerable to such media exposure. However, because of demand characteristics, evidence is mixed. Therefore, we minimized demand characteristics and explored whether media body ideals would trigger restrained eaters to report negative (negative mood, weight dissatisfaction) or positive (positive mood, weight satisfaction) effects. We also hypothesized that this change (negative or positive) would encourage food intake. Restrained and unrestrained eaters (n = 107) memorized media or control images. Restrained eaters exposed to media images reported decreased weight satisfaction and increased negative mood, but their food intake was not significantly affected. Perhaps paying advertent attention to the images caused goal-related negative affect, which triggered restraint.     

Imagining ethical globalization: The contributions of a care ethic

Approaches to global ethics have drawn on a number of diverse theoretical traditions, such as Kantianism and utilitarianism. While emerging frameworks contribute to a growing awareness of and interest in ethics within a global society, the values that they prioritize are not adequate for realizing a just, equitable and fair system of global governance. This article considers the possibilities of an alternative ethic—a feminist ethic of care—and explores how it can bear on present circumstances, including global inequity and injustice. This care ethic has been put forward as a viable normative approach to politics and policy. Little attention, however, has been paid to the potential of a care ethic within the globalization and ethics debate. This article illustrates how the values and corresponding principles of care, grounded in relationships and responsibilities, are essential to responding adequately to the current challenges of globalization. By examining the relevance of care in this context, the article seeks to broaden dominant ethical worldviews and contribute to the articulation of normative tools for examining globalization while at the same time avoiding the trappings of conventional universality—the abstract and a priori thinking typically associated with conceptions of global ethics.     

Relational dynamics of charismatic organization: The complementarity of love and power

Abstract: This paper outlines a new theory of structural transformation in charismatic systems by postulating a complementary relationship between love and power. Radical reorganization of social organization, the function of charismatic systems, requires mobilizing and realigning enormous amounts of social energy. The source of this social energy is love. When patterned as communion, love fuses the group into an undifferentiated whole and releases the social energy previously locked up as institutionalized structure.

Released from structure or form, however, social energy is highly volatile and produces immense pressures towards instability. Counterbalancing the pressure from communion, a strong, collective order of power functions to harness and align the energy, thereby promoting group stability and enhancing the prospects for structural transformation. Data from a national study of sixty urban communal organizations are used to ground key aspects of the theory.
