Rings whose proper factors are right perfect

We show that practically all the properties of almost perfect rings discovered by Bazzoni and Salce in "Almost perfect domains" (Colloq. Math. 95 (2) (2003), 285-301) for commutative rings hold in the non-commutative setting

Attachment Theory and Maternal Drug Addiction: The Contribution to\ua0Parenting interventions.

Children\u2019s emotional and relational development can be negatively influenced bymaternal substance abuse, particularly through a dysfunctional caregiving environment. Attachment Theory offers a privileged framework to analyze how drug addiction can affect the quality of adult attachment style, parenting attitudes and behaviors toward the child, and how it can have a detrimental effect on the co-construction of the attachment bond by the mother and the infant. Several studies, as a matter of fact, have identified a prevalence of insecure patterns among drug-abusing mothers and their children. Many interventions for mothers with Substance Use Disorders have focused on enhancing parental skills, but they have often overlooked the emotional and relational features of the mother\u2013infant bond. Instead, in recent years, a number of protocols have been developed in order to strengthen the relationship between drug-abusing mothers and their children, drawing lessons from Attachment Theory. The present study reviews the literature on the adult and infant attachment style in the context of drug addiction, describing currently available treatment programs that address parenting and specifically focus on the mother\u2013infant bond, relying on Attachment Theory

Applying Augmented Survey Data to Produce More Accurate, Precise, and Internationally Comparable Estimates of Poverty within the 50 United States

This paper introduces a series of augmentations to the Current Population Survey to allow for more accurate estimations of American poverty outcomes and a more fruitful integration of the U.S. into comparative research. The augmentations address three shortcomings in recent poverty research, including (1) severe measurement error in the data from which U.S. poverty estimates are most often derived, (2) the conceptualizations of poverty adopted within U.S.-centric research, and (3) the masking of substantial cross-state variation in poverty outcomes across the 50 United States. Specifically, the augmentations, made public for future researchers to apply, partially correct for the underreporting of four means-tested transfers, establish an internationally comparable conceptualization of poverty, and increase sample sizes for more-precise state-level estimates. The findings illustrate the extent to which prior studies have overestimated the incidence of poverty within the U.S. and have conceptually undervalued the immense heterogeneity of poverty outcomes across the 50 states

Implicit attitude toward caregiving: The moderating role of adult attachment styles

Attachment and caregiving are separate motivational systems that share the common evolutionary purpose of favoring child security. In the goal of studying the processes underlying the transmission of attachment styles, this study focused on the role of adult attachment styles in shaping preferences toward particular styles of caregiving. We hypothesized a correspondence between attachment and caregiving styles: we expect an individual to show a preference for a caregiving behavior coherent with his/her own attachment style, in order to increase the chance of passing it on to offspring. We activated different representations of specific caregiving modalities in females, by using three videos in which mothers with different Adult Attachment states of mind played with their infants. Participants' facial expressions while watching were recorded and analyzed with FaceReader software. After each video, participants' attitudes toward the category "mother" were measured, both explicitly (semantic differential) and implicitly (single target-implicit association task, ST-IAT). Participants' adult attachment styles (experiences in close relationships revised) predicted attitudes scores, but only when measured implicitly. Participants scored higher on the ST-IAT after watching a video coherent with their attachment style. No effect was found on the facial expressions of disgust. These findings suggest a role of adult attachment styles in shaping implicit attitudes related to the caregiving system

The Role of Father Involvement and Marital Satisfaction in the Development of Family Interactive Abilities: A Multilevel Approach.

The study aims to investigate the development of family interactions from pregnancy to preschool age in a longitudinal perspective, using multilevel analysis. Also, it explored the impact of couple relationship and father involvement in childcare on the developmental trend of the quality of mother\u2013father\u2013child interactions. One hundred and three primiparous families were assessed at 7th month of pregnancy, 4th, 9th, and 18th months of child\u2019s life and during preschool age (36\u201348th), using the observational procedure named, Lausanne Trilogue Play. Parents\u2019 perception of marital satisfaction was assessed with the Dyadic Adjustment Scale at each point of measure; moreover, in the postnatal assessment, parents completed the Father Involvement Questionnaire. Results showed that family interactions increase over time. Secondly, a decrease of marital adjustment is associated with an improvement of the quality of family interactions. Moreover, father involvement predicts the quality of family interactions from the earliest stages of child\u2019s life. In a longitudinal perspective, family interactions and marital quality show opposite developmental trends and father\u2019s involvement represents a particularly important feature of the family

Infant massage and quality of early mother-infant interactions: Are there associations with maternal psychological wellbeing, marital quality, and social support?

Infant massage programs have proved to be effective in enhancing post-natal development of highly risk infants, such as preterm newborns and drug or HIV exposed children. Less studies have focused on the role of infant massage in supporting the co-construction of early adult–child relationships. In line with this lack of literature, the present paper reports on a pilot study aimed at investigating longitudinally the quality of mother–child interactions, with specific reference to emotional availability (EA), in a group of mother–child pairs involved in infant massage classes. Moreover, associations between mother–child EA, maternal wellbeing, marital adjustment, and social support were also investigated, with the hypothesis to find a link between low maternal distress, high couple satisfaction and high perceived support and interactions of better quality in the dyads. The study involved 20 mothers and their children, aged between 2 and 7 months, who participated to infant massage classes. The assessment took place at three stages: at the beginning of massage course, at the end of it and at 1-month follow-up. At the first stage of assessment self-report questionnaires were administered to examine the presence of maternal psychiatric symptoms (SCL-90-R), perceived social support (MSPSS), and marital adjustment (Dyadic Adjustment Scale); dyadic interactions were observed and rated with the Emotional Availability Scales (Biringen, 2008) at each stage of data collection. The results showed a significant improvement in the quality of mother–child interactions, between the first and the last evaluation, parallel to the unfolding of the massage program, highlighting a general increase in maternal and child’s EA. The presence of maternal psychological distress resulted associated with less optimal mother–child emotional exchanges, while the hypothesis regarding couple satisfaction and social support influence were not confirmed. These preliminary results, if replicated, seem to sustain the usefulness of infant massage and the importance of focusing on early mother–infant interactions

La stima dei benefici del traffico divertito

In alcuni paesi europei (ad esempio Italia, Francia) è prassi comune, nella valutazione dei progetti di trasporto pubblico, stimare i benefici per gli utenti che passano da un modo di trasporto all’altro come la differenza tra il costo generalizzato del modo originale e quello del nuovo modo. In questo paper si sottolinea che tale metodologia di stima è scorretta e si punta ad aprire un dibattito sulla questione. Dato l’uso diffuso dei questa metodologia, la questione sollevata ha conseguenze significative in termini di policy, soprattutto perché gli investimenti in progetti di trasporto pubblico possono in realtà generare benefici per gli utenti sostanzialmente inferiori rispetto a quelli stimati, e quindi la loro giustificazione in termini di benessere può essere messa in discussione

Cognitive functioning, clinical profile and life events in young adults addicted to drugs. Does being a girl make a difference?

Objective: Gender features play a fundamental role as risk factors in drug addiction, entailing differences in vulnerability, onset, drug use and clinical trajectories. Even if increasing empirical evidence has attested that drug abuse in emerging adulthood is associated with cognitive impairments, personality disorders and psychological distress, limited research has analyzed these aspects from a gender perspective. The present research focuses on gender differences in youths (18–24 years of age) diagnosed with substance use disorders (SUDs), in order to detect possible differences between females and males as regards their neuropsychological functioning, clinical profiles and past life experiences. Method: Neuropsychological functioning (neuropsychological battery Esame Neuropsicologico Breve-2), the severity of the symptomatology (Symptom Checklist-90-Revised), personality profile and disorders (Shedler Westen Assessment Procedure-200) and life history were assessed in two groups of young adults with SUDs, 20 males and 20 females (mean age = 21 years, SD = 2.2). Participants were recruited in a therapeutic community in Venice, Italy. Results: Girls showed less cognitive impairment but higher psychological distress with respect to boys; between the two groups, no differences emerged regarding the personality profiles. The girls’ life histories presented more experiences of abuse and maltreatment; they also moved more quickly from substance use to dependence. Boys, instead, were more involved in criminal activity. Conclusions: Given our results, it seems that gender differences manifest early, at emerging adulthood. Consequently, a gender-oriented treatment for drug addiction should be offered even at an early age, focusing on early adverse experiences and their potential traumatic effect on girls. By contrast, young men seem to rely on compromised cognitive functions, which require a specific treatment approach, since they constitute a crucial factor for individual adjustment and treatment outcomes. Results should be interpreted relative to some limitations (such as the small sample size and the preliminary and cross-sectional nature of the research), and future studies are require

Alexithymia in young adults with substance use disorders: Critical issues about specificity and treatment predictivity

Several studies have reported high rates of alexithymia in drug-dependent individuals, but supporting evidence attests association between alexithymia and a variety of psychiatric disorders, raising doubts about its specificity. Moreover, controversies are emerging about alexithymia assessment: self-report measures present shortcomings with respect to discriminant validity and reliability. As regards treatment for substance use disorders (SUDs), alexithymia has been linked to poorer outcomes, but the results are inconsistent. The aim of the present study is to investigate alexithymia in substance-dependent young adults by examining: (a) the specificity of alexithymia in drug-dependent inpatients, compared to healthy individuals and patients with psychiatric disorders (behavioral and emotional disorders) and (b) the predictivity of alexithymia in determining treatment outcomes in terms of relapses, drop outs from treatment and the rate of relapse per month of treatment. Two studies were conducted to fulfill these aims: Study 1 and Study 2. Study 1 involved 90 late adolescents, aged 17-21. To fulfill the first aim, 30 inpatients diagnosed with SUD were compared with 30 healthy controls and 30 individuals referred to an outpatient neuropsychiatric unit (a). The participants completed the Toronto Alexithymia Scale-20 (TAS-20) and the Symptom Checklist-90-Revised (SCL-90-R). The results indicated that both clinical groups reported higher TAS-20 scores than the non-clinical subjects, but they did not differ from each other (a); moreover, a large correlation was detected between alexithymia and depressive symptoms, as assessed by the SCL-90-R. Study 2 involved 55 inpatients with SUD recruited in a therapeutic community. The participants completed the TAS-20, and clinicians filled out the Observer Alexithymia Scale (OAS). No association was found between self-report and observational measures. Neither self-reported nor observed alexithymia predicted the number of relapses, drop-out from treatment, or the rate of relapses per month of treatment (b). When the interaction with gender was explored, the global score of alexithymia and the "Distant" OAS subscale predicted the number rate relapses only in males. The TAS-20 did not discriminate between the clinical groups. The limited ability of both observed and self-reported measures in predicting treatment outcome raises questions on the specificity of alexithymia among the substance-dependent inpatient population
