Formation of a 'splitting pattern' associated with L1 2 precipitates in Ir-Nb alloys

A cuboidal L1 2 phase forms in the fcc matrix of an Ir-Nb alloy. Under some conditions, a rod- or plate-like fcc structure can be observed in this phase. This is similar to the 'splitting pattern' observed in some Ni-based alloys. To understand the formation mechanism of this structure, samples were heated under different conditions. Microstructure evolution during ageing was observed by transmission electron microscopy. We observed a splitting pattern only when the L1 2 precipitates were already formed in the as-cast condition after additional heat treatment at the ageing temperature. In this case, the composition of the L1 2 phase was not equilibrated. We conclude that the splitting pattern appears owing to a kinetic phenomenon when the L1 2 phase changes to the equilibrium composition.     

On Impediments to the Process of Individuation

A clinical case is presented at length with a view to understanding how the healthy fear of incest, which favours the process of individuation, may come into conflict with the fear of leaving childhood and becoming adult. Among the consequences of this conflict is a sort of paralysis or impediment to living which may be converted into hate. The inquiry mainly regards anxiety, fear, hate and aggression as factors which conspire in holding an individual back from his path in life. The affects are taken into consideration in accordance with Fromm's theory of aggression and his ''syndrome of decay'' diagnostic scheme, which results from the confluence and interaction of incestuous symbiosis, narcissism and destructiveness. Emphasis is placed on mechanisms of repression and splitting of hate not employed in aggression. Repressed and split hate may sustain para-hallucinatory symptoms and produce terror. This view offers an explanation of the perturbing symptomatology that afflicted the patient presented here and also shows the power of hate as a bond, as concomitant cause of the mother fixation and as obstacle to the process of individuation.     

The perversion of language in the analyst's activity: Navigating the rhythms of embodiment and symbolization

Abstract

In this short text, the problem of how “the talking cure” itself can become a perverse relation is considered and illustrated with a brief clinical vignette. Contributions coming from the work of Stern in infant research and Lacan in post-Freudian thought illuminate the potential for experience to be split off through the use of language itself. These perspectives are brought to bear on thinking about representation, splitting, and perversion as a basis for considering a clinical instance in which patient and analyst enact a perverse relation constituted by the way in which the patient uses the analyst's language to construct a sado-masochistic perversion of the treatment process. Within the clinical episode, Stein's reformulation of perversion, informed by Ogden's observations and expanding Stoller's earlier contribution, provides a basis for considering how the analyst was able to use attention to the body-based countertransferential experience to repair a sense of “erasure” that was being accomplished for both analyst and analysand through the enactment.     

Individual and institutional defences against primitive anxieties: Counselling in prison

Abstract

This paper describes a counsellor's attempts to understand the unconscious dynamics affecting the process of counselling women in prison. The social system of the prison serves to defend both prisoners and officers against powerful anxieties about the potential for sadistic attack originating from primitive states of mind, that is persecution, helplessness and destructiveness. The implications of the rigid means of defence are considered, and die role of unconscious guilt motivating the need for external punishment is briefly explored. Emphasis is placed on the role of splitting and projection in the management of potentially overwhelming feelings of guilt, and fear of punishment. The author develops the premise that there is in effect an institutional requirement that prisoners remain in the paranoid-schizoid position because of the feared consequences were they to experience depressive anxieties.     

Dr John Hunter Padel 1913–1999

SUMMARY

With the help of clinical material from two female patients with whom acting out was a major feature of their treatment I have examined the connection between acting out behaviour and separation anxiety.

To begin with, I have drawn on Freud's conception of acting out and have shown that this kind of behaviour can be closely associated with transference in that both can act as a resistance as well as an aid to the psychoanalytic process.

The link between acting out and preverbal experience is commented on and attention is given to the defensive splitting of the primary object during early development.

It is then suggested that one of the essential roots associated with acting out behaviour is that of object loss and separation.

The clinical examples show that if the child separates in a strongly hostile manner from the mother then acting out associated with separations during analysis is going to be greater.

In view of the deficits in the early mother child relationships of the two patients described I adopted a therapeutic strategy based less on confrontation and limit setting and more on a consistent attempt to understand what was being communicated in the acting out behaviour.     

The cognitive structure of movements in classical dance

AimsThis study was designed to elicit differences in the mental representations of two basic movements from classical ballet, the Pirouette en dehors and the Pas assemblé, stored in long-term memory of dancers of different skill-levels.MethodThe movements were demonstrated and explained verbally to professional ballet dancers, amateur dancers, and non-dancers. Subsequently, participants were assigned to a hierarchical sorting (splitting) task in which Basic Action Concepts (BACs) of the movements had to be sorted according to their functional relevance in movement execution. The task was presented as verbal labels on a computer screen. The responses were subjected to the application of a new analytical method, called SDA-M, which includes a hierarchical cluster analysis. The method enabled eliciting cognitive structures of the movements in the participants' long-term memory, and thus enabled comparing these cognitive structures in subjects of different skill-level.ResultsParticipants of different skill-level showed movement-specific differences in their mental representation structures in long-term memory. A similar structure was noted in advanced amateurs and professionals for the Pirouette en dehors, which referred to the functional phases of the movement, and less functional representations were noted in beginners and novices. For the Pas assemblé, the experts' representation structure was different from that of amateurs and novices, pointing toward differences in movement execution. It is concluded that movement representations of this kind in long-term memory might provide the basis for motor control in skilled ballet movements in the form of suitably organized perceptual-cognitive reference structures.ImplicationsThe results point toward a unique mental representation as a function of skill-level and movement nature. Individual and group results obtained with the applied method can be implemented to support (mental) training methods in classical dance practice.     

Direct evidence that an apparent splitting pattern of gamma particles in Ni alloys is a stage of coalescence

High-resolution electron microscopy is used to determine the translation order domains of gamma particles in arrangements formed during Ostwald ripening in the alloy Ni-12at.%Al. Such arrangements have been often identified with the operation of a mechanism of particle splitting in the late stages of the coarsening process, that is when the elastic strain contribution becomes predominant. It is shown that the translation order domains are not identical in such a particle array. This leads to the conclusion that particle splitting is not necessarily the mechanism responsible for the formation of such characteristic particle arrangements. Instead, particle migration can also be considered to be the responsible mechanism for the formation of such a correlated gamma-particle spatial distribution observed in Ni-based alloys.     

Food and violence: Childhood violence and emotional abuse as complicating factors in the inpatient treatment of eating disorders

SUMMARY

This paper considers the treatment, on an inpatient eating disorders ward, of patients who have suffered violence and emotional abuse during childhood. The complex web of relationships surrounding these patients is discussed, and it is suggested that there are multiple transferences — to the institution, to various members of staff, and to other patients — and that splitting of these transferences is inevitable. Staff experience powerful countertransference feelings, related to the patient's violent history. A central task for the staff team as a whole is to understand and contain the patient's disturbance — taking on, tolerating, and processing the projections. This demands the close working-together of the members of the multidisciplinary team, so that staff can together openly examine the patient's interaction with them and their own emotional responses to the patient and to other members of staff. If these responses are not understood by the ward staff, they can lead to conflict and inappropriate decisions. On the other hand, if the staff team together can build up a picture of the patient's relationships on the ward, and their meaning for the patient, this picture, like a particular projection of the world in an atlas, provides a ‘map’ of the patient's inner world. This ‘map’ can be used by the staff team in navigating their interactions with the patient. It can also assist the psychotherapist in her work to help the patient recognise and, eventually, own the split-off parts of herself.     

Twinning in the structure of the ‘decagonal’ phase Al65Cu20Co15

Abstract

The existence of twinning in the pseudo-decagonal phase Al₆₅Cu₂₀Co₁₅ has been established through TEM studies. From electron diffraction patterns, a rhombic crystalline lattice with a very large unit cell is easily identified. Diffraction patterns for microtwinned regions exhibit splitting and distortion of the reflections which is a result of the overlap of lattices which are rotated by 36° with respect to one another. While patterns from single components of the twins exhibit only pseudo-tenfold symmetry, those from the microtwinned regions exhibit nearly perfect tenfold symmetry.     

The stability of a double-slab configuration of two-phase particles confined in a third phase

The stability of a double-slab configuration of two-phase particles confined in a third phase is studied as a function of shape in two and three dimensions. The condition of stability against splitting one phase in the particle into two separate identical slabs is shown to be the sum of the wetting factor and the change in the interface area relative to the shape of the two-phase particle. It is found that the double-slab configuration can be stable for a wide range of wetting factors and shapes.     

Secondary traumatization among former prisoners of wars' adult children: the mediating role of parental bonding

Background and Objectives: The aversive impact of combat and parents' combat-induced posttraumatic stress disorder (PTSD) on young children has been examined in a few studies. However, the long-term toll of war captivity on secondary traumatization (ST) and the parental bonding of adult children remain unknown. This study examined ST symptoms and parental bonding among adult children of former prisoners of war (ex-POWs' children) that were compared to adult children of comparable veterans (controls' children). Furthermore, we examined the mediating role of parental bonding and exposure to stress in the association between group and ST symptoms. Design: A correlative, cross-sectional study. Methods: Participants were Israeli ex-POWs' children (N = 98) and controls' children (N = 90), whose fathers fought in the 1973 Yom Kippur War. All participants completed a battery of self-reported questionnaires. Results: Ex-POWs' children reported a higher number of ST symptoms and lower levels of fathers' care, as compared to controls' children. Importantly, exposure to stress stemming from fathers' behaviors and fathers' care was found to mediate the association between research group and ST. Conclusions: Forty years after the war ended, the experience of living with ex-POWs is associated with ex-POWs' children psychological outcome.     

Doing it for the team: Soccer coaches' identity leadership predicts players' effort,turnover intentions,and performance

ObjectivesThe present research investigates how coaches' identity leadership predicts individual and team outcomes in soccer. Specifically, we tested hypotheses that coaches' identity leadership would be associated with players' perceptions of (a) higher team effort, (b) lower turnover intentions, (c) better individual performance, and (d) better team performance. In addition, we aimed to examine the relationship between coaches' identity leadership and increased team identification of players and the degree to which the associations of identity leadership with these various outcomes were mediated by players' strength of team identification.DesignWe conducted a cross-sectional study of male soccer players in Germany.MethodThe final sample consisted of 247 male soccer players nested in 24 teams that completed measures of their coaches' identity leadership, team identification, team effort, turnover intentions, and individual/team performance.ResultsAnalysis revealed a positive relationship between coaches' identity leadership and team effort, as well as individual and team performance. Moreover, coaches' identity leadership was associated with lower turnover intentions. There was also evidence that the relationships between identity leadership and the investigated outcomes were mediated by team identification.ConclusionsThese findings support claims that coaches' identity leadership is associated with better individual and team outcomes because it helps to build a sense of ‘we’ and ‘us’ in the team they lead.     

Interaction of athletes' resilience and coaches' social support on the stress-burnout relationship: A conjunctive moderation perspective

ObjectiveIn line with Smith's (1986) cognitive-affective model of athletic burnout, the purpose of this study was to examine the conjunctive effects of athletes' resilience and coaches' social support on the relationship between life stress and burnout.DesignCross-sectional, self-report survey.MethodsA total of 218 student-athletes (M_age = 20.04 yrs, SD = 1.32; males = 159, females = 59) participating in team and individual sports completed life stress, resilience, coaches' social support, and athlete burnout scales. Hierarchical multiple regression analyses with one- two- and three-way interactions examined disjunctive and conjunctive moderations.ResultsResilience and coaches' social support conjunctively moderated the stress-burnout relationship. Specifically the interaction of athletes' resilience with coaches' informational and tangible social support moderated athletes' stress-burnout relationship in high and low life stress conditions.ConclusionsWe suggest coaches provide useful social support and foster athletes' resilience to prevent stress-induced burnout in athletes.     

The (Neglected) role of the father in Children's mental health

BackgroundAlthough the bulk of the literature on child development, historically, has focused on the significant role of the mother, less attention has been given to that of the father. Therefore, more attention has been given to fathers’ roles in the last 20–30 years.AimThe aim of the current review was to explore the role of the father on a child's development.MethodsAn extensive literature search using 'Psycharticles', ‘PsychInfo’, and ‘Google Scholar’ databases using terms like 'father's role', 'child/children's', 'child development', and 'mental health' was conducted to achieve the objective of the study.ResultsFathers were found to play a significant role in nurturing their children. Fathers are considered to be important for the development of the child's autonomy, the shaping of gender identity, and the development of the moral system of the child. Usually, he is the one who establishes the feeling of security in the child's mind. He is considered to be the protector and defender of the family Freud's position is that the father is the symbol of security, power, and authority for the child.ConclusionAlthough the original aim of the research was to draw a line between parents' roles in the family and shed light on the father's role, the findings suggest that the fundamental concept in nurturing children depends on the complementary roles of parents as children need their parents equally.     

Measuring explicit attitude toward doping: Review of the psychometric properties of the Performance Enhancement Attitude Scale

ObjectivesDoping use is seldom an accident – it is a deliberate action often requiring considerable commitment. Attitudes are known to influence this type of action and hence they are likely to be predictive of doping-related behaviours. To measure ‘doping attitude’, a valid and reliable tool is required.DesignThis paper briefly reviews methodological issues in doping attitude research, introduces the Performance Enhancement Attitude Scale (PEAS) and provides a comparative analysis of its reliability and validity as a self-reported measure of a generalized doping attitude.MethodsThe scale's reliability was examined with Cronbach's internal consistency coefficient and test–retest correlations using data from 9 independent studies encompassing 7 years. Confirmatory factor analysis was performed to assess the scale's structure. Known-groups' validation strategy was employed to examine construct validity in 4 studies.ResultsEstimates of the PEAS' internal consistency (ranged between .71 and .91 across various samples) provided good evidence of the scale's simultaneous reliability. The chi-square/df ratio in all cases was below the threshold with an average of 1.85 (ranging from 1.370 to 2.291), indicating an acceptable measurement model fit. Theoretically expected difference in doping attitudes was found between doping users and non-users with elevated PEAS scores from users, as well as predictable dynamics of PEAS scores across the repeated measures, provided support for construct validity of the scale.ConclusionThe psychometric properties of the 17-item unidimensional PEAS suggest that the scale is a useful tool for measuring self-declared attitudes toward doping, with adequate reliability and promising validity estimates. Suggestions are discussed for the continuous scale development and validation process.     

The social context as a determinant of teacher motivational strategies in physical education

ObjectivesThe purpose of the study was to provide an in-depth analysis of how the Physical Education (PE) teaching context influences teachers' motivational strategies towards students.DesignQualitative semi-structured interviewsMethodsUsing Self-determination theory (Deci, E. L., & Ryan, R. M. (2000). Psychological Enquiry, 11, 227-268) as a guiding framework, semi-structured interviews of 22 PE teachers were examined using categorical content analysis.ResultsThe teachers perceived that an emphasis on student assessment and the time constraints associated with PE lessons often compelled them to use teaching strategies which conflicted with their beliefs about the most appropriate ways to motivate students. The teachers' own performance evaluations and pressure to conform to other teachers' methods also influenced the teachers' motivational strategies, but these influences were often congruent with their teaching beliefs. Additionally, the teachers discussed how perceived cultural norms associated with the teacher-student relationship impacted upon their chosen motivational strategies. These cultural norms were reported by different teachers as either in line, or in conflict with their teaching beliefs. Finally, the influence of the teachers' perceptions of their students helped produce strategies that were congruent with their beliefs, but often different to empirically suggested strategies.ConclusionsIt is important that teacher beliefs are targeted in education programs and that the teaching context aid in facilitating adaptive motivational strategies.     

Is it acceptable for a physician to break confidentiality in the case of sexually transmitted diseases? A mapping of young Kuwaiti's views

IntroductionConfidentiality is essential for the establishment of trust between physicians and their patients.ObjectivesThe circumstances under which it is acceptable to young Kuwaiti for a physician to break confidentiality to protect the spouse of a patient with a sexually transmitted disease (STD) were examined.MethodA sample of 263 young Kuwaiti indicated the acceptability of breaking confidentiality in 48 scenarios that were all possible combinations of five factors: disease severity, time taken by the physician to discuss with the patient, the patient's intent to inform the spouse about the disease, the patient's intent to adopt protective behaviors, and the decision to seek the advice of an expert in infectious diseases before breaking confidentiality.ResultsThrough cluster analysis, four qualitatively different positions were found: Quite never acceptable (6% of the sample, mostly males), Depends on husband's willingness to inform (3%), Depends on husband's protective behavior (29%, mostly females), and Quite always acceptable (32%). The remaining participants did not express any clear view.ConclusionIn Kuwait, students’ trust in the medical profession is, therefore, not likely to be seriously undermined if, from time to time, and in well-specified cases, individual physicians decide to break confidentiality when facing dilemmas of the kind examined in the current study.     

De l’efficacité d’un « exergame » sur le stress perçu et le sentiment d’auto-efficacité chez un patient atteint de la maladie de Parkinson : résultats d’un protocole à cas unique de type ABAB

IntroductionRehabilitation is of paramount importance in Parkinson's disease because it compensates for deficiencies in the body's structures and functions and preserves relative autonomy for as long as possible. Nevertheless, people with this disease report low adherence to physical activity.ObjectiveThe purpose of this research is to examine the potential psychological benefits of using an “exergame”, a “serious game” based on physical exercise in the functional rehabilitation of Parkinson's disease, including stress and self-efficacy.MethodA single case ABAB protocol (n = 1) over 4 weeks, 1 week per phase, 3 observation points per phase, was developed. Our variables were measured by questionnaires and we used visual and statistical analysis to interpret changes in scores between Phases A and B.OutcomesThe “exergame” intervention appears to improve perceived stress and self-efficacy. The results are accompanied by an exploratory interview, reporting qualitative changes.ConclusionThe use of “exergame” in Parkinson's disease seems promising, and does not harm the person. But the methodology used is not sufficient to conclude on its real effectiveness. Further studies are needed.
