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.     

Transformational education for psychotherapy and counselling: a relational dynamic approach

ABSTRACT

An evolving relational dynamic approach to psychotherapy and counselling education is described. Key themes integrated within the approach are the learning community and transformational relationships. Learning is a reciprocal change process involving students, teachers, supervisors and therapists in overlapping learning communities. Drawing on evidence that effective outcomes in therapy correlate with effective aspects of the therapeutic relationship, the relational dynamic approach emphasises the findings of attachment and intersubjectivity theorists. The intersubjective matrix of infant/caregiver and client/therapist is mirrored and embodied in the relational ethos of training and actively engaged in group supervision. An emphasis on embodied relating is discussed, drawing on infancy studies and recent neuroscientific findings     

The impact of the socio-economic crisis on intrapsychic and intersubjective processes within the therapeutic relationship: Implications for the ethical practice of counselling psychology and psychotherapy

Using attachment and mentalisation theories as a framework, the present paper aims to explore the impact of the current socio-economic crisis on the micro-processes and interpersonal dynamics that emerge between client and therapist as well as the ethical dilemmas that surface within the context of the therapeutic relationship. The first part of the paper focuses on the intrapsychic level and the subjective appraisal and experience of the crisis, as this may differ from individual to individual as well as the unique meaning-making processes that take place for clients and therapists alike. It is argued that the socio-economic crisis itself cannot be seen as an entity that is entirely independent and external to the individual but as a phenomenon that interacts in unique ways with the individual’s inner current and past experience. The second part focuses on the exploration of intersubjective processes that emerge between client and therapist, in particular the transference-countertransference dynamic, as this develops within conditions of increased arousal and anxiety. The role and responsibility of counselling psychologists in preserving reflexivity, empathy and a mentalising stance (through supervision and personal therapy) are highlighted in order to safeguard the ethical and competent practice of counselling psychology.     

The fieldwork model: An anthropological perspective on the process of change in long-term psychoanalytic psychotherapy

The question of what takes place in the psychoanalytic consulting room, and whether it has any therapeutic effect on the patient, has consistently been behind various criticisms of the long-term psychoanalytically informed therapies. When it comes to goal-oriented talking therapies –the only ones favoured by the state mechanism – statistical proof of their efficacy is thought of as proof of their scientific value. However, disciplines such as social anthropology have consistently based their complex understanding of social phenomena in qualitative data. This article draws upon the anthropological fieldwork model. It also looks at how anthropological theory has evolved as a result of the increasing centrality of the fieldwork model and a gradual acceptance of the inter-subjective process. It aims to highlight how lived experience, the paradigm on which the fieldwork model is based, constitutes a highly effective way of understanding in depth the patient and the patient's history. Such understanding is in turn the main factor behind profound and lasting psychological change. It is argued here that psychotherapy research and practice could be enhanced by following the example of anthropological qualitative research.     

Children in psychodynamic psychotherapy: changes in global functioning

This study was part of the Erica Process and Outcome Study. The aim was to investigate if children's global functioning improves after psychodynamic psychotherapy. Variables that may predict changes in global functioning were examined both statistically and qualitatively, for example, the child's age and gender; diagnosis and comorbidity; treatment variables. The sample consisted of 33 children (five to 10 years of age) who participated in psychodynamic psychotherapy with parallel work with parents. Twenty-nine children had at least one DSM-IV diagnosis, and 15 children had comorbid conditions. At the start of psychotherapy, the most frequent diagnoses were attention disorder and disruptive behaviour. Child psychotherapists rated the children's global functioning using CGAS and HCAM. Large effect sizes were obtained (d = 1.80 and d = 1.98). However, no statistical correlations were found between global functioning and the selected variables. In order to illuminate the complex connection between process and outcome the study was complemented with in-depth case studies where data were taken from questionnaires, completed by the child therapists every third month. Two child therapies were selected: one in which the therapist rated a large change and one in which a small change was rated (CGAS). The analysis showed that important individual change, for example, attainment of formulated goals, was not always reflected in the change rated using the CGAS. Findings suggest that psychodynamic child psychotherapy can be beneficial. However, further research is needed to identify factors that contribute to change in children's global functioning.

Chapter 10. Despite False Hopes,Forced Transition Creates Growth

SUMMARY

In this chapter, I discuss how each of six stages applied to the reported experiences of the volunteers, drawing examples from field logs and interviews and the data reflected in the previous chapters.     

权力基础理论:对应生存需要的权力

权力是社会关系和社会活动的核心,对应于生存需要,与人们的生活品质息息相关。采用心理–生态途径,权力基础理论将其界定为个体依据环境限制与供给满足自身需要的能力,并识别出6种基本权力类型,同时阐述了权力动态性如何通过增生性交易导致或加剧社会不平等。该理论试图从人际和群际心理层面探讨权力的起源问题,并将其与一般社会不平等现象建立联系,为权力的社会心理学研究提供了一个崭新的视角。     

Exploring the Non-objectified Character of Dao in the Laozi: A Modem Articulation

This article focuses on the interpretation of heng dao 恆 道 (sometimes translated as "the constant dao") and its fundamental character in the Laozi.It argues against the prevailing interpretation of dao as an unchanging metaphysical substance or reality,and maintains that the fundamental feature of heng dao is both dynamic and eternal.Heng dao is beyond language because of its dynamic character,but the Laozi nevertheless strives to express it in three aspects:1) its flexibility and adaptability as represented in the metaphor of water;2) its movement of reversal and return;3) and in its existential significance as a guide for life.Heng dao can be called the non-objectified dao,which produces law,principle,rule,method,and so on.Looked at in this way,the dynamic character of heng dao can be called non-objective.     

Nonlinear Growth Models as Measurement Models: A Second-Order Growth Curve Model for Measuring Potential

Recent methodological work has highlighted the promise of nonlinear growth models for addressing substantive questions in the behavioral sciences. In this article, we outline a second-order nonlinear growth model in order to measure a critical notion in development and education: potential. Here, potential is conceptualized as having three components—ability, capacity, and availability—where ability is the amount of skill a student is estimated to have at a given timepoint, capacity is the maximum amount of ability a student is predicted to be able to develop asymptotically, and availability is the difference between capacity and ability at any particular timepoint. We argue that single timepoint measures are typically insufficient for discerning information about potential, and we therefore describe a general framework that incorporates a growth model into the measurement model to capture these three components. Then, we provide an illustrative example using the public-use Early Childhood Longitudinal Study–Kindergarten data set using a Michaelis-Menten growth function (reparameterized from its common application in biochemistry) to demonstrate our proposed model as applied to measuring potential within an educational context. The advantage of this approach compared to currently utilized methods is discussed as are future directions and limitations.
