Dynamic properties of an ultrafine-grained Mg–Zn–Zr alloy

The effect of ultrafine-grained structure formation in Mg–Zn–Zr alloy ZK60 on its mechanical response was investigated at strain rates ranging from quasi-static to dynamic regimes. The study demonstrated that the strength characteristics of the material rise significantly with increasing strain rate, while its ductility is reduced. These effects are particularly pronounced in the dynamic loading regime, at strain rates in the (1?5)?×?10²?s^?1 range. In the ultrafine-grained alloy ZK60, the energy absorption per unit volume, W, is enhanced by grain refinement by a factor as high as eight for the highest strain rate of 5?×?10²?s^?1 investigated. The analysis is focused on the microstructure features that bring about the observed improvement of the tensile characteristics, as well as the deformation and fracture modes prevalent at different strain rates. The results obtained contribute to the exploration and understanding of dynamic behaviour of magnesium alloys.     

EDUCATION,SOCIAL CREATIVITY,AND THE EVOLUTION OF SOCIETY

The evolution of society, the transcendence of existing social structures, and how society creates itself rests in a function of education. In this article the author examines education's work as that of social creativity. The need for pedagogies of “educate hope” and “imaginative possibilities” is explored. Social epistemology and social imaginary are discussed as dimensions of social creativity within the postmodern society. The aesthetic imperative in education is argued as important to developing the capacities and capabilities in youth to imagine alternative future possibilities of democratic society. The author concludes by examining the role of education in the evolution of society.     

Validation of a Coping Scale in an African Context

The research aims were to compile and validate a multi-dimensional coping measure, taking African-centred coping behaviour into consideration. In a pilot study the Setswana-COPE (S-COPE) and the Africultural Coping Systems Inventory (ACSI) were administered to Setswana-speaking participants (N = 274). Selected items from these measures were combined into a single 35-item measure, the N-COPE, which was administered to another group of Setswana-speaking participants (N = 1050) together with a number of measures of psychological well-being. Reliability coefficients yielded a Cronbach alpha of.74 for the N-COPE total. Criterion-related validity was determined by correlating the N-COPE with other measures of psychological well-being. It was concluded that the N-COPE showed promising results for use in this context, but further refinement and validation is necessary.     

Primitivism and the Analogy between Colors and Values

The analogy between colors and values is strongly interlinked with the idea that these properties are by nature dispositions or response‐dependent properties. Indeed, that colors are essentially visible, and values are inherently motivational, cries out for a dispositional or a response‐dependent account. Recently, Primitivism has challenged the viability of the dispositional account of colors, taking the apple, for instance, to be “gloriously, perfectly, and primitively red.” Unsurprisingly, the attack on the dispositional account of colors has found a moral analogue in the view that values are sui generis irreducibly primitive properties. The question this article addresses is whether given Primitivism the analogy between colors and values is preserved; or in other words, whether Primitivism breaks the bond between the dispositional account and the analogy between colors and values.     

Action across emptiness

This paper examines how autism may affect the processing and containing of emotions and sensations. At the beginning of life we can hypothesise that the baby develops two means of processing experience: containment that involves a sensory and mimetic trace of relational experience (proto-containment) and containment which, through the α function and projective and introjective functions translates feelings into meaning (♀/♂). Both these means of processing emotional experience remain active throughout life but oscillate the one with the other. The main hypothesis of this work is that the autistic child is not able to oscillate between real containment (♀/♂) and a primitive form of proto-containment. The author aims to explore, through clinical material, the factors which may promote this oscillation. Autistic children often use non-verbal communication. The author examines how a particular type of action can cross the relational void in the therapeutic relationship through a process that can transform feelings of great distress in the analyst via acts that can be described as an Act of Faith, as described by Bion. This form of action that can cross the void is like an artistic performance.

Knowledge ascriptions and the psychological consequences of changing stakes

One of the many ways that ‘deflationary’ and ‘inflationary’ theories of truth are said to differ is in their attitude towards truth qua property. This difference used to be very easy to delineate, with deflationists denying, and inflationists asserting, that truth is a property, but more recently the debate has become a lot more complicated, owing primarily to the fact that many contemporary deflationists often do allow for truth to be considered a property. Anxious to avoid inflation, however, these deflationists are at pains to point out that the truth property, on their view, is not a property of any significant interest. Correspondingly, inflationists have seen this as an opportunity to refine what kind of property they think truth is, which—according to them—moves their views beyond deflationism. The upshot of this is that there are number of different accounts in the literature of what distinguishes an inflationary truth property from a deflationary one, or—as it is sometimes put—what distinguishes a ‘substantive’ property from an ‘insubstantive’ one. This has made it hard to pin down exactly what is at issue at the metaphysical level between deflationists and inflationists, which makes it increasingly hard to see how debates between them are properly phrased. Given that these positions represent the two central attitudes towards truth in contemporary debates, this makes for a serious obstacle for the project of discerning the correct theory of truth. The aim of this paper is to discern the best way to distinguish between substantive and insubstantive properties, and thus to restore some focus to these debates. I argue that the three central distinctions in the literature fail, and offer what I take to be a more promising distinction in terms of a graded distinction between abundant and sparse properties.

Assessment of dispositional forgiveness in adolescence: a contribution to the Italian validation of the Forgiveness Likelihood Scale

ABSTRACT

The current study investigated the factor structure, factorial invariance, and reliability of the Italian version of the Forgiveness Likelihood Scale (FLS) among 604 adolescents in Italy (217 boys and 387 girls) with a mean age of 16.6 years (SD?=?1.3). The FLS is a 10-item Likert-type scale created to assess the predisposition to forgive across situations. The sample was randomly split into two subsamples to investigate the FLS structure. Results indicated a unidimensional structure, and factorial invariance was found for the factor solution across gender. Scale reliability was adequate, revealing appropriate internal consistency (α?=?.75). Evidence for convergent validity was also found. The results suggested that the Italian version of the FLS can be reliably used to measure forgiveness among Italian adolescents. Practice implications and future research directions are discussed.     

Towards Gratitude to Nature: Global Environmental Ethics for China and the World

This paper asks what should be the basis of a global environmental ethics.As Gao Shan has argued,the environmental ethics of Western philosophers such as Holmes Rolston and Paul Taylor is based on extending the notion of intrinsic value to that of objects of nature,and as such it is not very compatible with Chinese ethics.This is related to Gao's rejection of most—if not all—Western "rationalist" environmental ethics,a stance that I grant her for pragmatic reasons (though I remain neutral about it theoretically).Gao argues that the Daoist notion of living in harmony with nature can instead become the basis of a Chinese environmental ethics.However,the involved Daoist conception of living in harmony with nature is,in my view,based on an aesthetic property.The paper argues that despite the appeal of the Daoist view for a Chinese environmental ethics,an aesthetic property cannot provide the basis for a global environmental ethics.The paper also considers another version of Daoist environmental ethics,which does not rely on an aesthetic notion,but I argue that it too fails as such a candidate.As an alternative,the paper considers and applies contemporary Western thinkers on gratitude (such as Robert Emmons and Elizabeth Loder),proposing that gratitude to nature (environmental gratitude)can indeed provide the needed basis.
