Memory and correlation effects in the exciton-phonon kinetics

Memory and correlation effects in the interband absorption from quantum wells due to exciton-phonon dynamics are investigated. They are traced back to the frequency dependence and matrix character of the self energy arising in a 2nd Born theory. It is found that interpeak absorption increases with respect to the case in which this memory and correlation effects are neglected.Comment: NOEKS8 Proceeding

Making sense of ourselves and others: a contribution to the community-diversity debate

In recent years, a debate has played out concerning the relationship between two of Community Psychology's core values: promoting diversity and promoting a sense of community. To elaborate on this dialectical relationship, we propose to inscribe it within the broader framework of the identity-otherness dynamics, which currently underpins a variety of disruptive socio-political processes across Europe (e.g., the decrease of solidarity in dealing with the refugee crisis, the spreading of eurosceptic attitudes, and the waves of xenophobia and populism). All these phenomena entail, either as a premise or as a consequence, the negation of otherness and diversity. Some theories in cultural and semiotic psychology suggest that a deeper understanding of the community-diversity dialectics would benefit from taking into account not only the traditional socio-cognitive processes, but also the symbolic and meaning-making processes that envelop the experience of self and the experience of otherness. This perspective would also help in developing community interventions that acknowledge both the need for belonging and identity, and the need for diversity

Emotion Regulation and Parental Bonding in Families of Adolescents With Internalizing and Externalizing Symptoms

Parental bonding and emotional regulation, while important to explain difficulties that may arise in child development, have mainly been studied at an individual level. The present study aims to examine alexithymia and parental bonding in families of adolescents with psychiatric disorders through different generations. The sample included a total of 102 adolescent patients with psychiatric disorders and their parents. In order to take a family level approach, a Latent Class Analysis was used to identify the latent relationships among alexithymia (Toronto Alexithymia Scale), perceived parental bonding (Parental Bonding Instrument) and the presence of adolescent internalizing or externalizing psychiatric symptoms (Youth Self-Report). Families of internalizing and externalizing adolescents present different and specific patterns of emotional regulation and parenting. High levels of adolescent alexithymia, along with a neglectful parenting style perceived by the adolescent and the father as well, characterized the families of patients with internalizing symptoms. On the other hand, in the families with externalizing adolescents, it was mainly the mother to remember an affectionless control parental style. These results suggest the existence of an intergenerational transmission of specific parental bonding, which may influence the emotional regulation and therefore the manifestation of psychiatric symptoms

An Attempt to Conceptualize the Phenomenon of Stigma toward Intimate Partner Violence Survivors: A Systematic Review

The objectives of the present manuscript were to review the literature on stigma toward survivors of intimate partner violence (IPV) and to identify the most widely used assessment techniques to investigate this issue. The PRISMA guidelines were followed, and the systematic review was registered in PROSPERO, registration number: CRD42022327410. PsycINFO, Scopus, Web of Science, and PubMed were searched. Two authors selected and extracted data from eligible studies. In total, 4220 hits were returned from the database search, and of them, 24 articles met the inclusion criteria. The articles included in the review confirm the presence of stigma toward IPV survivors, which can be divided into public stigma and self-stigma. Specifically, 17 studies were related only to public stigma, 1 study focused only on self-stigma, and 6 articles investigated aspects related to both public and self-stigma. Both qualitative and quantitative studies have been conducted on this topic. The considerations on the methodologies and assessment measures used in the included studies will be discussed in the results section. Based on the research included, it was possible to develop a contribution to the definition of stigma, which will be discussed in the article

Parent\u2019s perception of children\u2019s fear: from FSSC-IT to FSSC-PP

Studies involving parents' reports about children's fears and multiple informant comparisons are less extended than investigations on children's self-reporting fear schedules. Starting with the Italian version of FSSC-R, the FSSC-IT, the main aims of this study were to adapt a schedule for parents' perception of their children's fear: the FSSC-Parent Perception. Its psychometric properties were examined in a large sample of parents (N = 2970) of children aged 8-10 years. Exploratory and confirmatory factorial structures were examined and compared with the Italian children's ones. Mother vs. father, children's gender and school age group effects were analyzed. The confirmatory factor analysis confirmed a four correlated factors solution model (Fear of Danger and Death; Fear of Injury and Animals; Fear of Failure and Criticism; Fear of the unknown and Phobic aspects). Some effects related to child gender, age group, mother vs. father, were found. The FSSC-PP properties supported its use by parents to assess their children's fears. A qualitative analysis of the top 10 fears most endorsed by parents will be presented and compared with children's fears. Clinical implications about the quality of parent-child relationships where discussed, comparing mothers and fathers, and parents' perception about daughters' and sons' most endorsed fears

Near-field spectra of quantum well excitons with non-Markovian phonon scattering

The excitonic absorption spectrum for a disordered quantum well in presence of exciton-acoustic phonon interaction is treated beyond the Markov approximation. Realistic disorder exciton states are taken from a microscopic simulation, and the deformation potential interaction is implemented. The exciton Green's function is solved with a self energy in second order Born quality. The calculated spectra differ from a superposition of Lorentzian lineshapes by enhanced inter-peak absorption. This is a manifestation of pure dephasing which should be possible to measure in near-field experiments.Comment: 8 pages, 7 figure

Rorschach assessment in suicide survivors: Focus on suicidal ideation

Background: The study of Suicidal ideation (SI) in people bereaved through suicide (Suicide Survivors, SSs) could be hampered by the person's willingness to admit it, or by their limited awareness of it. Our main hypothesis is that SI is common in these people, especially if they are parents or children of the victim. For its potential in shedding light on specific unconscious processes, Rorschach test was chosen for our investigation, for the first time in SSs literature. Rorschach suicide ideation and selected variables were further analyzed to better delineate their psychological profile. Method: Rorschach according to Exner's Comprehensive System was administered to 21 people bereaved through suicide presenting as outpatients at SOPROXI Project Service-Padova Mental Health Center- and 23 healthy controls. Beck Depression Inventory (BDI) was routinely administered to SSs and considered in the study. Results: T-tests showed significantly higher mean SI score (S-Con) as it emerged from the Rorschach test S-Con scores in SSs compared to control participants. SI found only weak correlation with the BDI item in which SSs can explicitly state the desire for their death. Within-group analysis revealed higher S-Con mean scores in bereaved children and parents of the victim compared to other kind of kinships. Morbid content (MOR) has been fund as the most characterizing variable in SSs' S-Con in terms of effect size, followed by a low number of responses with an ordinary form (X +%). Human movements (M), Special Scores related to thought slippage (ALOG, FABCOM2, INCOM2, and CONTAM) and poor human representations (PHR) have been shown to be more significantly present in SSs compared controls. Discussion: Psychodynamic interpretations of our results are provided. Clinical practice should consider Rorschach as one of eligible tools of investigation on this field
