Spousal support for personal goals and relationship satisfaction among women during the transition to parenthood
2010
The aim of this three-wave cross-lagged longitudinal study was to examine the prospective relationships between women’s goal-related spousal support and their relationship satisfaction during the transition to parenthood. Two-hundred and forty-six Finnish women who were either married or cohabited (45% primiparous; 55% multiparous) filled in questionnaires on personal projects (Little, 1983) and related spousal support, relationship satisfaction (Spanier, 1976), and background data three times: in their early pregnancy; one month before childbirth; and three months after childbirth. Among the primiparous women the results showed a cumulative cycle of goal-related spousal support and relati…
Separating mismatch negativity (MMN) response from auditory obligatory brain responses in school-aged children
2013
Mismatch negativity (MMN) overlaps with other auditory event-related potential (ERP) components. We examined the ERPs of 50 9- to 11-year-old children for vowels /i/, /y/ and equivalent complex tones. The goal was to separate MMN from obligatory ERP components using principal component analysis and equal probability control condition. In addition to the contrast of the deviant minus standard response, we employed the contrast of the deviant minus control response, to see whether the obligatory processing contributes to MMN in children. When looking for differences in speech deviant minus standard contrast, MMN starts around 112 ms. However, when both contrasts are examined, MMN emerges for …
Reflection 2008: The State of Science, Religion and Consciousness
2008
2008 is a year in which the world’s economical, financial and even political systems are going through unprecedented turmoil and earth-shaking transformations. Yet, it seems that nothing has changed in Science except that many scientists are sadly loosing there jobs and/or funding. Religion also seems to be stagnant with the exceptions that various hastened prophecies of 2012 are flourishing and charitable contributions are in drastic declines. Under these historical, uncertain, sad but hopeful circumstances, it is appropriate and even urgent that we further reflect on the state of Science and Religion. It is also appropriate that we reflect on the state of consciousness research because ou…
Mothers' parenting stress and adolescents' emotional separation: The role of youngsters' self orientation
2015
The study examined the association among mothers’ parenting stress, adolescents’ emotional separation and self-orientation toward connectedness. Participants were 194 Italian adolescents, aged from 15 to 19 years (mean age = 17.39, SD = 1.18), and their mothers, aged from 33 to 64 years (mean age = 44.35, SD = 5.40). General findings showed that adolescents’ emotional separation may not necessarily be associated with their mothers’ parenting stress, but both of these variables may be related to adolescents’ personal characteristics, which may contribute to define parent-child relationship. Particularly, adolescents’ orientation towards a connected self was associated negatively with emotion…
Chemogenetic Suppression of the Subthalamic Nucleus Induces Attentional Deficits and Impulsive Action in a Five-Choice Serial Reaction Time Task in M…
2020
The subthalamic nucleus (STN), a key component of the basal ganglia circuitry, receives inputs from broad cerebral cortical areas and relays cortical activity to subcortical structures. Recent human and animal studies have suggested that executive function, which is assumed to consist of a set of different cognitive processes for controlling behavior, depends on precise information processing between the cerebral cortex and subcortical structures, leading to the idea that the STN contains neurons that transmit the information required for cognitive processing through their activity, and is involved in such cognitive control directly and dynamically. On the other hand, the STN activity also …
Perinatal and Wharton's jelly-derived mesenchymal stem cells in cartilage regenerative medicine and tissue engineering strategies
2011
Stem cells can be found in embryonic and extraembryonic tissues as well as in adult organs. In particular, research in the last few years has delineated the key features of perinatal stem cells derived from fetus-associated tissues. These cells show multiple differentiation potential, can be easily expanded ex vivo, and raise no ethical concerns as regards their use. Several reports indicate that cells isolated from Wharton's jelly (WJ), the main component of umbilical cord extracellular matrix, are multipotent stem cells that express markers shared by other mesenchymal stem cells (MSC) and give rise to different mature cell types belonging to all three germ layers. Moreover, WJ-MSC display…
Non-coding RNAs and other determinants of neuroinflammation and endothelial dysfunction: regulation of gene expression in the acute phase of ischemic…
2021
Ischemic stroke occurs under a variety of clinical conditions and has different pathogeneses, resulting in necrosis of brain parenchyma. Stroke pathogenesis is characterized by neuroinflammation and endothelial dysfunction. Some of the main processes triggered in the early stages of ischemic damage are the rapid activation of resident inflammatory cells (microglia, astrocytes and endothelial cells), inflammatory cytokines, and translocation of intercellular nuclear factors. Inflammation in stroke includes all the processes mentioned above, and it consists of either protective or detrimental effects concerning the “polarization” of these processes. This polarization comes out from the intera…
Selecting between Competitors in Multiplication Tasks: An Explanation of the Errors Produced by Adolescents with Learning Difficulties
1997
Two experiments were conducted in order to determine the nature of the difficulties encountered by learning disabled (LD) adolescents in the resolution of multiplication problems ( a b, where a and b vary between 2 and 9). A response production task (Experiment 1) revealed that the incorrect responses generally belonged to the table of one of the two operands, and that the order of difficulty of the problems was the same for the LDs as for normal children, adolescents, and educated adults as reported in the literature. This result suggests that the difficulties are not solely due to memory problems. Experiment 2 tested the hypothesis that these difficulties were caused by a problem in inhi…
Identity Processing Orientation, Cognitive and Behavioural Strategies and Well-being
1997
The aim of this study was to investigate interrelationships among the identity negotiation styles that people use, the cognitive and behavioural strategies they deploy, and their sense of subjective well-being. To examine this, 198 American and 109 Finnish college students completed the Identity Style Inventory, the Strategy and Attribution Questionnaire, Rosenberg’s Self-esteem Scale, and the revised Beck’s Depression Inventory. Results showed that people with an information-oriented identity style reported the highest level of self-esteem, those with a normative style had the most stable self-conceptions, and those with a diffuse/avoidant style displayed the highest level of depressive s…
The accumulation of problems of social functioning as a long-term process: Women and men compared
2000
Structural equation modelling was used to analyse the developmental processes involved in the accumulation of problems of social functioning from age 8 to age 36 in men ( n = 152) and women ( n = 145). The accumulation of risk factors in childhood and adolescence, including low control of emotions (aggressiveness and anxiety), school problems (poor adjustment, success, and motivation), and problems in the family (parental drinking and low socioeconomic status), predicted career instability, early timing of parenthood, and a sense of failure at age 27 in both sexes. Similarly, the accumulation of problems of social functioning (e.g. poor financial standing, poor intimate relationships, and d…
