Gender differences in the relationship between attachment styles, self-esteem and online deception: A mediation model

Online Deception is growing as a topic of research due to its potential risks for mental health and behaviors. This study explored the relationships between attachment styles and intentional misrepresentation of oneself in online dating (i.e., online deception) and investigated the mediating role of self-esteem. A cross-sectional online survey was conducted with voluntary Italian participants (N = 272) to test the proposed hypotheses. It was found that anxious attachment styles positively predicted online deception. Also, self-esteem was found to be mediator between anxious attachment styles and online deception, as well as between close attachment styles and online deception. Our results demonstrate the need to develop prevention interventions that target individuals’ styles of attachment that in turn foster self-esteem which co-contribute to promote a sensible and healthy use of online dating

Prenatal parental representations: Influences on perceived romantic couple adjustment and infant's temperament during pregnancy and after the infant's birth

Objective: The present work aimed to evaluate the differences between fathers' and mothers' prenatal parental representations, the differences between pre- and postnatal perceptions of couple adjustment, and whether the quality of prenatal parental representations is associated with the perception of couple adjustment and with the perception of infant temperament at 3 months. Background: Within a multifactorial, transactional model, several studies indicated that prenatal parental representations are relevant to the quality of infant–parent relationship and the child's development. Method: Couples experiencing their first pregnancy (n = 40) (mothers: Mage = 33.7 years, SD = 5,1 years; fathers: (Mage = 37.4 years, SD = 5.6 years) responded to the Parental Representations Interview During Pregnancy and the Dyadic Adjustment Scale during the seventh month of pregnancy. When couples' infant was 3 months of age, the parents completed the Infant Behavior Questionnaire-R to assess infant temperament. Results: Analyses revealed that mothers and fathers who had an unbalanced and unintegrated parental representation perceived their couple adjustment as less cohesive, and this was related to a more negative perception of the child's temperament. Conclusions: Prenatal parental representations were found to be a significant variable in terms of their influence on the quality of pre- and postnatal parents' romantic couple adjustment and on the infant's temperament. Implications: It is important to include both mothers and fathers to further our understanding of parental influence on a child's development and to enhance the efficacy of preventive programs since pregnancy

Analysis of S-band solid-state transmitters for the solar power satellite

The possibility of replacing the Reference System antenna in which thermionic devices are used for the dc-to-microwave conversion, with solid-state elements was explored. System, device, and antenna module tradeoff investigations strongly point toward the desirability of changing the transmitter concept to a distributed array of relatively low power elements, deriving their dc power directly from the solar cell array and whose microwave power outputs are combined in space. The approach eliminates the thermal, weight, and dc-voltage distribution problems of a system in which high power tubes are simply replaced with clusters of solid state amplifiers. The proposed approach retains the important advantages of a solid state system: greatly enhanced reliability and graceful degradation of the system

Gender and country differences in academic motivation, coping strategies, and academic burnout in a sample of Italian and Russian first-year university students

Background: The first year of university represents a challenging period that requires students to make significant investments in adaptive resources to face the new academic environment. The present study intends to contribute to the controversial discussion of gender differences in academic motivation, coping strategies, and academic burnout. This cross-sectional study examined above-mentioned constructs among first-year university students in a cross-cultural context. Methods: The sample consisted of 637 Italian and 496 Russian first-year university students (n = 1133), 40.3% of whom were females. The participants’ ages ranged from 17 to 23 years, with a mean age of 18.75 years (SD = 1.07). To assess academic motivation, coping strategies, and academic burnout, participants responded to the Academic Motivation Scale (AMS), the Coping Inventory for Stressful Situations (CISS), and the Maslach Burnout Inventory–Student Survey (MBI–SS) application. Results: The findings reveal gender and country differences in academic motivation, emotion and avoidance oriented coping strategies, and emotional exhaustion and expands previous studies in this educational area. Conclusion: Given the technical nature of the research topic, the target audience for our study is academic career guidance practitioners, who can apply the findings to the design of effective programmes aimed at improving positive academic goals and reducing the tendency to switch academic courses or abandon the university among first-year students

Perinatal Depression and Anxiety Symptoms, Parental Bonding and Dyadic Sensitivity in Mother–Baby Interactions at Three Months Post-Partum

The quality of the early parent-infant relationship is crucial for the child's optimal development, and parental sensitivity plays a key role in early interactions. The purpose of the study was to evaluate the influence of maternal perinatal depression and anxiety symptoms on dyadic sensitivity at three months post-partum, also considering a large set of maternal and infant variables. At the third trimester of pregnancy (T1) and at three months postpartum (T2), 43 primiparous women filled in a set of questionnaires evaluating symptoms of depression (CES-D) or anxiety (STAI), the woman's parental bonding experiences (PBI), alexithymia (TAS-20), maternal attachment to the baby (PAI, MPAS) and the perceived social support (MSPSS). At T2 mothers also completed a questionnaire on infant temperament and took part in the CARE-Index videotaped procedure. Dyadic sensitivity was predicted by higher maternal trait anxiety scores in pregnancy. In addition, the mother's experience of being cared for by her father in childhood was predictive of her infant's lower compulsivity, while paternal overprotection predicted higher unresponsiveness. The results highlight the influence of perinatal maternal psychological well-being and maternal childhood experiences on the quality of the dyadic relationship. The results may be useful to foster mother-child adjustment during the perinatal period

First-Time Mothers’ and Fathers’ Developmental Changes in the Perception of Their Daughters’ and Sons’ Temperament: Its Association With Parents’ Mental Health

Objective: Most studies investigating the role of parenting behaviors on a child’s development are directed to mothers. However, recent analyses show that mothers and fathers have a different influence on a child’s functioning, specifically her/his temperament. The present study explored the developmental change of parents’ perception of their daughters’ and sons’ temperament and its association with parental mental health problems. Methods: The sample included 188 parents (94 couples) and their at-term 94 babies (55.3% boys, 44.7% girls). Assessments by self-reports were conducted at 3 (Time 1) and 12 (Time 2) months after the children’s birth; at Time 1, mothers and fathers independently answered: the State–Trait Anxiety Inventory (STAI), the Edinburgh Postnatal Depression Scale (EPDS), and the Infant Behavior Questionnaire (IBQ-R). At Time 2, EPDS, STAI, and IBQ-R were again administered to mothers and fathers. Results: In general, mothers and fathers would give similar descriptions of their child’s temperament throughout the first year of life; however, infant temperament showed developmental changes as well as gender differences. Mother and father anxiety and depression symptoms are associated with the infants’ negative affectivity. Also, mothers with high anxiety and depression levels perceive their infants with a minor tendency to approach novelty, to seek environmental stimulation, and to express/experience positive emotions. Conclusion: The results highlight the need to screen for infants’ temperament vulnerabilities in the context of maternal and paternal depression in order to protect the child from behavioral, cognitive, and emotional difficulties and to create specific programs aimed at preventing dysfunctional parent–infant relationships

Estimation of (co)variance components of nematode parasites resistance and somatic cell count in dairy sheep

Nematode parasites and mastitis are the major animal health constraints in sheep. The aim of this study was estimating the genetic (co)variances of nematode parasites resistance and somatic cell count in dairy sheep. From 2000 to 2008, Somatic Cell Score (SCS) and Faecal Egg Count (FEC) records were available on an experimental population consisting of 949 backcross ewes and 806 their daughters. Data were processed independently for each subpopulation in order to adjust for specific environmental effects and to obtain lactation records for both traits to be used in the genetic analysis. Variance components estimation was performed by using the REML method applied to a bi-trait repeatability animal model. Heritabilities of lactation SCS (LSCS) and FEC were 0.19 and 0.16. Genetic correlation was 0.21, whereas phenotypic correlation was 0.01. The estimated heritabilities confirm that both traits could be selected by the classical quantitative approach. The genetic correlation estimate between LSCS and FEC suggests that selection for one of the two traits would not have any detrimental effect on the other one

Polyphenols rich diets and risk of type 2 diabetes

Type 2 diabetes is an increasing health concern worldwide. Both genetic and environmental risk factors as improper dietary habits or physical inactivity are known to be crucial in the pathogen-esis of type 2 diabetes. Polyphenols are a group of plant-derived compounds with anti-inflammatory and antioxidant properties that are associated with a low prevalence of metabolic conditions charac-terized by insulin resistance, including obesity, diabetes, and hypertension. Moreover, there is now full awareness that foods that are rich in phytochemicals and polyphenols could play an important role in preserving human cardiovascular health and substantial clinical evidence indicates that regu-lar dietary consumption of such foods affects favorably carbohydrate metabolism. This review briefly summarizes the evidence relating dietary patterns rich in polyphenols with glucose metabolism and highlights the potential benefits of these compounds in the prevention of type 2 diabetes

Association of arterial stiffness with a prothrombotic state in uncomplicated nondiabetic hypertensive patients

Background and aims: Past studies reported a significant contribution of a prothrombotic state to the development and progression of target organ damage in hypertensive patients. Stiffening of arterial vessels is associated with aging and hypertension, and additional factors could contribute to this process. This study was designed to examine the relationships between arterial stiffening and the hemostatic and fibrinolytic system. Methods: In 128 middle-aged, nondiabetic, essential hypertensive patients without major cardiovascular and renal complications, we measured coagulation markers that express the spontaneous activation of the hemostatic and fibrinolytic system and assessed stiffness of the arterial tree by measurement of the carotid/femoral pulse wave velocity (cfPWV) and pulse wave analysis with calculation of the brachial augmentation index (AIx). Results: Levels of fibrinogen (FBG), D-dimer (D-d), and plasminogen activator-inhibitor 1 (PAI-1) were significantly higher in patients with PWV and AIx above the median of the distribution. FBG, D-d, and PAI-1 were significantly and directly related with both cfPWV and AIx, and multivariate regression analysis indicated that the relationships of D-d and PAI-1 with both cfPWV and AIx and of FBG with AIx, were independent of age, body mass index, severity and duration of hypertension, use of antihypertensive drugs, blood glucose, and plasma lipids. Conclusion: In middle-aged, uncomplicated, nondiabetic patients with essential hypertension, spontaneous activation of plasma hemostatic cascade and impaired fibrinolysis is significantly and independently associated with stiffening of the arterial tree
