TL;DR: An interdependence analysis of social value orientation revealed that relative to individualists and competitors, prosocial individuals exhibited greater levels of secure attachment and reported having more siblings, especially sisters.
Abstract: The authors adopt an interdependen ce analysis of social value orientation, proposing that prosocial, individualistic, and competitive orientations are (a) partially rooted in different patterns of social interaction as experienced during the periods spanning early childhood to young adulthood and (b) further shaped by different patterns of social interaction as experienced during early adulthood, middle adulthood, and old age. Congruent with this analysis, results revealed that relative to individualists and competitors, prosocial individuals exhibited greater levels of secure attachment (Studies 1 and 2) and reported having more siblings, especially sisters (Study 3). Finally, the prevalence of prosocials increased—and the prevalence of individualist s and competitors decreased—from early adulthood to middle adulthood and old age (Study 4). Traditional theories and insights assume that the principle of rational self-interest or economic man reflects the prevailing motivation among humankind (Luce & Raiffa, 1957; Von Neuman & Morgenstern, 1947; cf. Roth, 1988). However, more recent theoretical developments have indicated that individuals systematically differ in the manner in which they approach interdependent others. Some people are inclined to give interdependent others the benefit of the doubt and approach them cooperatively, whereas other people are inclined to approach interdependent others in a less cooperative manner. Such individual differences are related to social value orientation, defined as stable preferences for certain patterns of outcomes for oneself and others (McClintock, 1978; Messick & McClintock, 1968). Although a variety of different social value orientations can be distinguished from a theoretical point of view (e.g., Knight & Dubro, 1984), in this article we address a three-category typology of social value orientation, examining differences between prosocial, individualistic, and competitive orientations. Prosocials tend to maximize outcomes for both themselves and others (i.e., cooperation) and to minimize differences between outcomes for

TL;DR: An analysis is presented of responses of a variety of normal tissues in animals to fractionated irradiations and it is shown that the influence of fractionation can be described on the basis of a simple formula relating the effectiveness for induction of cellular effects to the dose per fraction.
Abstract: An analysis is,,presented of responses of a variety of normal tissues in animals to fractionated irradiations. It is shown that the influence of fractionation can be described on the basis of a simple formula relating the effectiveness for induction of cellular effects to the dose per fraction: F(D) = 1D + a2D2. The ratio a 1 a 2 is derived as an essential parameter for, the description of fractionation effects. It is concluded that the values of a 1 a 2 for responses of various tissues range widely from 2 to 10 Gy. On the basis of the review of radiobiological data, a formalism is developed for the analysis and prediction of iso-effect relations for tissue tolerance, which can be used as an alternative to the nominal standard dose (NSD) formula of Ellis and its derived equations. An essential characteristic of the formalism is that three groups of tissue responses are distinguished which can be described with respect to fractionation effects by average values of a l a 2 = 10 ; 5 and 2.5 Gy, respectively. These groups comprise a l: a.o. skin and intestine; 2: connective tissue; 3:a.o. lung and vascular system. Dose rate effects can be described by a similar formalism. For the calculation of equivalent total doses to be applied in clinical treatments, a concept denoted Extrapolated Tolerance Dose (ETD) of Extrapolated Response Dose (ERD) is introduced. ETD is the tolerance dose for an infinite number of very small fractions. This concept is shown to be useful for the summation of different fractionated schedules and of low dose rate treatments. A number of examples is presented illustrating similarities and differences in comparison with calculations based on the NSD formula. An important feature of the described formalism is that it is directly based on radiobiological insights and it provides a more logical concept to account for the diversity of tissue responses than the assumption of different exponents of N and T in the NSD formula.

TL;DR: It is shown that the time dependence of correlation functions in an extended quantum system in d dimensions, which is prepared in the ground state of some Hamiltonian and then evolves without dissipation according to some other Hamiltonian, may be extracted using methods of boundary critical phenomena in d + 1 dimensions.
Abstract: We show that the time dependence of correlation functions in an extended quantum system in d dimensions, which is prepared in the ground state of some Hamiltonian and then evolves without dissipation according to some other Hamiltonian, may be extracted using methods of boundary critical phenomena in d + 1 dimensions For d = 1 particularly powerful results are available using conformal field theory These are checked against those available from solvable models They may be explained in terms of a picture, valid more generally, whereby quasiparticles, entangled over regions of the order of the correlation length in the initial state, then propagate classically through the system

TL;DR: The Task Force agreed on Good Practice Points to define clinical and electrophysiological diagnostic criteria for CIDP with or without concomitant diseases and investigations to be considered.
Abstract: BACKGROUND: Consensus guidelines on the definition, investigation, and treatment of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) have been previously published in European Journal of Neurology and Journal of the Peripheral Nervous System. OBJECTIVES: To revise these guidelines. METHODS: Disease experts, including a representative of patients, considered references retrieved from MEDLINE and Cochrane Systematic Reviews published between August 2004 and July 2009 and prepared statements that were agreed in an iterative fashion. RECOMMENDATIONS: The Task Force agreed on Good Practice Points to define clinical and electrophysiological diagnostic criteria for CIDP with or without concomitant diseases and investigations to be considered. The principal treatment recommendations were: (i) intravenous immunoglobulin (IVIg) (Recommendation Level A) or corticosteroids (Recommendation Level C) should be considered in sensory and motor CIDP; (ii) IVIg should be considered as the initial treatment in pure motor CIDP (Good Practice Point); (iii) if IVIg and corticosteroids are ineffective, plasma exchange (PE) should be considered (Recommendation Level A); (iv) if the response is inadequate or the maintenance doses of the initial treatment are high, combination treatments or adding an immunosuppressant or immunomodulatory drug should be considered (Good Practice Point); (v) symptomatic treatment and multidisciplinary management should be considered (Good Practice Point).
