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.     

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.     

The rise of information in an evolutionary universe

This paper outlines the grand scenario of cosmic evolution by examining the ongoing changes among radiation, matter and life in standard, big‐bang cosmology. Using aspects of non‐equilibrium thermodynamics and information science, we argue that it is the contrasting temporal behavior of various energy densities that have given rise to the environments needed for the emergence of galaxies, stars, planets, and life forms. We furthermore argue that a necessary (though perhaps not sufficient) condition—a veritable prime mover—for the emergence of such ordered structures of growing complexity is the expansion of the Universe itself. Neither demon‐strably new science nor appeals to non‐science are needed to explain the impressive hierarchy of developmental change, from quark to quasar, from microbe to mind.     

Electron spin resonance of hydrogenated amorphous silicon-carbon alloy films prepared by magnetron sputtering

Abstract

New electron spin resonance (ESR) lines with g¹ = 2·0017 and g₂ and g₃ = 2·0006 have been found in the ESR spectra of as-deposited a-Si_1–x C_x:H films prepared by magnetron sputtering of silicon in the gas mixtures of methane and argon. Similarities between the observed spectra and those for the E′ centre in glassy SiO₂ are discussed.     

Wind Power Planning Controversies and the Construction of ‘Expert’ and ‘Lay’ Knowledges

UK and Scottish planning policies include commitments to reflect the views of the public. However, this case study of one planning application for a wind farm in rural Scotland highlights the limited role played by lay knowledge within planning processes. The planning application process had two separate stages which structured the roles of lay and expert knowledge differently. Local objectors were able to influence the early planning application stage. However, this resulted in an appeals process (public inquiry) which was beyond the influence of lay people, and within which lay knowledge played only a marginal role. The early planning application stage enabled a wider range of knowledges to be relevant, perhaps even allowing lay knowledge to sideline expert knowledge. Within the inquiry such roles were reversed. Witnesses who could not back up their evidence with ‘reliable’ data or scientific reasoning were discredited as illegitimate and as having little to contribute to the inquiry process. Thus the inquiry constructed boundaries between expert and lay knowledge, in ways which diminished the role that lay knowledge might play. Whilst the construction of expert knowledge at the public inquiry played a central role in marginalising lay knowledge, it was central to all sides of the argument; the role of expert knowledge was reinforced by both the opposition group and the developers. Therefore, it is not only policy-makers and planning officials, but also lay people who act as though expert and lay knowledge can be clearly distinguished from one another.     

Modification of the optical band gap of polyethylene by irradiation with electrons and gamma rays

Irradiation of polymers has become an important technique in producing special materials for electronic applications. In this study, the effects of electron and gamma irradiation on ultra-high-molecular-weight polyethylene (UHMWPE) samples have been studied using UV–Vis absorption spectroscopy. The UHMWPE samples were irradiated with electron and gamma rays with doses ranging from 25 kGy up to 500 kGy. An increase in the optical absorption and a shifting from the UV–Vis towards longer wavelengths were observed. Concomitantly, a pronounced decrease in the optical band gap was recorded as a function of dose level. The optical band gap E _g varied from 2.86 eV for a pristine sample down to ～1.98 eV and ～2 eV for samples irradiated with gamma rays and electrons at the highest doses, respectively. A correlation between E _g and the number of carbon atoms N in a formed cluster is discussed in terms of a modified Tauc equation.
