Ocena wzajemnego przyciągania i partnerstwa w okresie menopauzy

Wstęp. Menopauza jest złożonym procesem fizjologicznym pomiędzy okresem rozrodczym i starością (senium). Złożoność problemów menopauzy może prowadzić do powikłań w relacji małżeńskich / partnerskich oraz w ocenie osobistej atrakcyjności. Celem badania była ocena wzajemnego przyciągania i partnerstwa w okresie menopauzy. Materiał i metoda. Badanie przeprowadzono w klinice ginekologicznej Szpitala Wojskowego z Polikliniką w Lublinie z wykorzystaniem badań diagnostycznych. Narzędziem badawczym był kwestionariusz stosowany do oceny charakterystyki badanej grupie, dobre małżeństwo Questionnaire (KDM-2), menopauza Rating Scale (polska wersja MRS-II) i SKAT skali wzajemna atrakcyjność. Wyniki poddano analizie statystycznej. Wyniki. Wyniki pokazują, że kobiety i mężczyźni różnią się znacznie w ocenie jakości relacji tylko pod względem poczucia rozczarowania. W grupie kobiet, poczucie rozczarowania jest wyższe niż u mężczyzn, co oznacza, że coraz więcej kobiet cierpi z powodu braku przyjemności bycia ze swoim partnerem. Ponadto, istnieją umiarkowanie silne, ale statystycznie istotne, ujemne korelacje między stanem psychicznym, autonomicznym, objawami moczowo-płciowego a oceną atrakcyjności partnera, ale tylko w przypadku kobiet. Wyższa ocena objawów menopauzy była związana z niższą oceną atrakcyjności partnera i słabszą potrzebą budowania ścisłych relacji z nimi, zmniejszony poziom postrzegania własnej relacji jako spełnienia siebie i własnej wartości, a także słabszym przekonaniem, że partnerzy mają podobne poglądy na temat relacji. Wnioski. Atrakcyjność partnera i jakość relacji jest oceniana znacznie wyższa przez mężczyzn niż kobiety. Wyższe wskaźniki objawów uciążliwości i irytacji podczas menopauzy wiążą się z niższą oceną atrakcyjności partnera tylko u kobiet. Wyższa ocena jakości, wiąże się z wyższą oceną atrakcyjności partnera, zarówno w przypadku kobiet jak i mężczyzn. Im bardziej zadowoleni są partnerzy z tych relacji, tym bardziej przyciągają się wzajemnie.Introduction. Menopause is a complex physiological process between reproductive period and old age (senium). The complexity of menopausal problems can lead to complications in marital relationships/partnerships and in the assessment of interpersonal attractiveness. The aim of the study was to evaluate the mutual attraction and partnerships during menopause. Materials and methods. The study was conducted in the Gynaecologic Clinic of the First Military Hospital and Policlinic in Lublin with the use of a diagnostic survey. The research tool included an independently developed questionnaire used to evaluate characteristics of the study group, Good Marriage Questionnaire (KDM-2), Menopause Rating Scale (Polish Version of the MRS-II) and SKAT mutual attractiveness scale. The results were subject to statistical analysis. Results. Results show that women and men differ significantly in the assessment of the quality of relationships only in terms of the sense of disappointment. In the group of women, the sense of disappointment is higher than in men’s, which means that more women suffer from the lack of pleasure from being with their partner. In addition, there are moderately strong, but statistically significant, negative correlations between mental, autonomic, urogenital symptoms and the rating of the partner’s attractiveness, but only in case of women. Higher rating of menopause symptoms annoyance was associated with lower assessment of the partner’s attractiveness and a weaker need to build a close relationship with them, a reduced level of perceiving one’s own relationship as fulfilment of the self and own values, as well as a weaker conviction that the partners share similar views on the relationship. Conclusions. The partner’s attractiveness and the quality of the relationship is rated significantly higher by men than women. Higher ratings of symptom nuisance and annoyance during perimenopause are associated with lower assessment of the partner’s attractiveness only in women. Higher quality assessment, therefore, is associated with higher assessment of the partner’s attractiveness, both in case of women and men. The more satisfied partners are with their relationship, the more attracted to each other they are

Why place matters in residential care: the mediating role of place attachment in the relation between adolescents’ rights and psychological well-being

Little evidence exists on the relationship between rights’ perceptions and well-being outcomes during the adolescence, and particularly in care, as well as on the mediating role of place attachment. Young people in residential care are psychologically and socially vulnerable, showing greater difficulties than their peers do in the family. Youth’s rights fulfilment in residential care may positively affect their psychological functioning together with positive attachments to this place. A sample of 365 adolescents in residential care settings (M = 14.71, SD = 1.81) completed a set of self-reported measures, specifically, the Rights perceptions scale, the Place attachment scale and Scales of psychological well-being. Results revealed significant mediating effects of place attachment (Global scale and subscales of Friends Bonding and Place Dependence) on the relationship between Participation and Protection rights in residential care and Psychological well-being (Positive Relations with others, Personal Growth and Self-Acceptance). The positive role of rights fulfilment in residential care, specifically participation opportunities, as well as the role of youth’s attachment to the care setting are discussed based on previous evidence and theoretical assumptions. A set of practical implications is described.info:eu-repo/semantics/acceptedVersio

Early season N₂O emissions under variable water management in rice systems: source-partitioning emissions using isotope ratios along a depth profile

Soil moisture strongly affects the balance between nitrification, denitrification and N2O reduction and therefore the nitrogen (N) efficiency and N losses in agricultural systems. In rice systems, there is a need to improve alternative water management practices, which are designed to save water and reduce methane emissions but may increase N2O and decrease nitrogen use efficiency. In a field experiment with three water management treatments, we measured N2O isotope ratios of emitted and pore air N2O (δ15N, δ18O and site preference, SP) over the course of 6 weeks in the early rice growing season. Isotope ratio measurements were coupled with simultaneous measurements of pore water NO3-, NH4+, dissolved organic carbon (DOC), water-filled pore space (WFPS) and soil redox potential (Eh) at three soil depths. We then used the relationship between SP&thinsp;×&thinsp;δ18O-N2O and SP&thinsp;×&thinsp;δ15N-N2O in simple two end-member mixing models to evaluate the contribution of nitrification, denitrification and fungal denitrification to total N2O emissions and to estimate N2O reduction rates. N2O emissions were higher in a dry-seeded&thinsp;+&thinsp;alternate wetting and drying (DS-AWD) treatment relative to water-seeded&thinsp;+&thinsp;alternate wetting and drying (WS-AWD) and water-seeded&thinsp;+&thinsp;conventional flooding (WS-FLD) treatments. In the DS-AWD treatment the highest emissions were associated with a high contribution from denitrification and a decrease in N2O reduction, while in the WS treatments, the highest emissions occurred when contributions from denitrification/nitrifier denitrification and nitrification/fungal denitrification were more equal. Modeled denitrification rates appeared to be tightly linked to nitrification and NO3- availability in all treatments; thus, water management affected the rate of denitrification and N2O reduction by controlling the substrate availability for each process (NO3- and N2O), likely through changes in mineralization and nitrification rates. Our model estimates of mean N2O reduction rates match well those observed in 15N fertilizer labeling studies in rice systems and show promise for the use of dual isotope ratio mixing models to estimate N2 losses.</p

Shape programming for narrow ribbons of nematic elastomers

Using the theory of Γ-convergence, we derive from three-dimensional elasticity new one-dimensional models for non-Euclidean elastic ribbons, i.e., ribbons exhibiting spontaneous curvature and twist. We apply the models to shape-selection problems for thin films of nematic elastomers with twist and splay-bend texture of the nematic director. For the former, we discuss the possibility of helicoid-like shapes as an alternative to spiral ribbons

"Don't try to teach me, I got nothing to learn": Management students' perceptions of business ethics teaching

[EN] Interest is growing towards including business ethics in university curricula, aiming at improving ethical behaviour of future managers. Extant literature has investigated the impact of ethics education on different ethics-related students' cognitive and/or behavioural outcomes, considering variables related to training programmes and students' demographic aspects. Accordingly, we aim at assessing students' understanding of business ethics issues, by focusing on the differences in students' perceptions depending on gender, age, work experience, and ethics courses taken. Testing our hypotheses on a sample of 307 management students at a Polish university, and controlling for social desirability bias, we obtained mixed and partially surprising results. We found significant differences in students' understanding of business ethics depending on their gender and age (female and older students showed more ethical inclinations), but not depending on having taken ethics courses-actually perceptions of such courses worsened after taking them. Besides, work experience was not a significant variable. Moreover, course exposure intensiveness (i.e., number of ethics courses completed), and time passed since completion of the latest course, did not confirm hypothesized effects on most of the dependent (sub)variables. These findings stimulate further questions and challenges for future research (e.g., around course design and methodology, and social/cultural/contextual issues).Tormo-Carbó, G.; Oltra, V.; Klimkiewicz, K.; Seguí-Mas, E.

Nonlinear weakly curved rod by Γ-Convergence

We present a nonlinear model of weakly curved rod, namely the type of curved rod where the curvature is of the order of the diameter of the cross-section. We use an approach analogous to the one for rods and curved rods and start from the strain energy functional of three dimensional nonlinear elasticity. We do not impose any constitutional behavior of the material and work in a general framework. To derive the model, by means of Γ-convergence, we need to set the order of strain energy (i.e., its relation to the thickness of the body h). We analyze the situation when the strain energy (divided by the order of volume) is of the order h 4. This is the same approach as the one used in Föppl-von Kármán model for plates and the analogous model for rods. The obtained model is analogous to Marguerre-von Kármán for shallow shells and its linearization is the linear shallow arch model which can be found in the literature

Use of an Atrial Lead with Very Short Tip-To-Ring Spacing Avoids Oversensing of Far-Field R-Wave

The AVOID-FFS (Avoidance of Far-Field R-wave Sensing) study aimed to investigate whether an atrial lead with a very short tip-to-ring spacing without optimization of pacemaker settings shows equally low incidence of far-field R-wave sensing (FFS) when compared to a conventional atrial lead in combination with optimization of the programming.Patients receiving a dual chamber pacemaker were randomly assigned to receive an atrial lead with a tip-to-ring spacing of 1.1 mm or a lead with a conventional tip-to-ring spacing of 10 mm. Postventricular atrial blanking (PVAB) was programmed to the shortest possible value of 60 ms in the study group, and to an individually determined optimized value in the control group. Atrial sensing threshold was programmed to 0.3 mV in both groups. False positive mode switch caused by FFS was evaluated at one and three months post implantation.A total of 204 patients (121 male; age 73±10 years) were included in the study. False positive mode switch caused by FFS was detected in one (1%) patient of the study group and two (2%) patients of the control group (p = 0.62).The use of an atrial electrode with a very short tip-to-ring spacing avoids inappropriate mode switch caused by FFS without the need for individual PVAB optimization.ClinicalTrials.gov NCT00512915

LSD but not lisuride disrupts prepulse inhibition in rats by activating the 5-HT2A receptor

Compounds that activate the 5-HT2A receptor, such as lysergic acid diethylamide (LSD), act as hallucinogens in humans. One notable exception is the LSD congener lisuride, which does not have hallucinogenic effects in humans even though it is a potent 5-HT2A agonist. LSD and other hallucinogens have been shown to disrupt prepulse inhibition (PPI), an operational measure of sensorimotor gating, by activating 5-HT2A receptors in rats. We tested whether lisuride disrupts PPI in male Sprague–Dawley rats. Experiments were also conducted to identify the mechanism(s) responsible for the effect of lisuride on PPI and to compare the effects of lisuride to those of LSD. Confirming a previous report, LSD (0.05, 0.1, and 0.2 mg/kg, s.c.) reduced PPI, and the effect of LSD was blocked by pretreatment with the selective 5-HT2A antagonist MDL 11,939. Administration of lisuride (0.0375, 0.075, and 0.15 mg/kg, s.c.) also reduced PPI. However, the PPI disruption induced by lisuride (0.075 mg/kg) was not blocked by pretreatment with MDL 11,939 or the selective 5-HT1A antagonist WAY-100635 but was prevented by pretreatment with the selective dopamine D2/D3 receptor antagonist raclopride (0.1 mg/kg, s.c). The effect of LSD on PPI is mediated by the 5-HT2A receptor, whereas activation of the 5-HT2A receptor does not appear to contribute to the effect of lisuride on PPI. These findings demonstrate that lisuride and LSD disrupt PPI via distinct receptor mechanisms and provide additional support for the classification of lisuride as a non-hallucinogenic 5-HT2A agonist

Modern Clinical Research on LSD

All modern clinical studies using the classic hallucinogen lysergic acid diethylamide (LSD) in healthy subjects or patients in the last 25 years are reviewed herein. There were five recent studies in healthy participants and one in patients. In a controlled setting, LSD acutely induced bliss, audiovisual synesthesia, altered meaning of perceptions, derealization, depersonalization, and mystical experiences. These subjective effects of LSD were mediated by the 5-HT2A receptor. LSD increased feelings of closeness to others, openness, trust, and suggestibility. LSD impaired the recognition of sad and fearful faces, reduced left amygdala reactivity to fearful faces, and enhanced emotional empathy. LSD increased the emotional response to music and the meaning of music. LSD acutely produced deficits in sensorimotor gating, similar to observations in schizophrenia. LSD had weak autonomic stimulant effects and elevated plasma cortisol, prolactin, and oxytocin levels. Resting-state functional magnetic resonance studies showed that LSD acutely reduced the integrity of functional brain networks and increased connectivity between networks that normally are more dissociated. LSD increased functional thalamocortical connectivity and functional connectivity of the primary visual cortex with other brain areas. The latter effect was correlated with subjective hallucinations. LSD acutely induced global increases in brain entropy that were associated with greater trait openness 14 days later. In patients with anxiety associated with life-threatening disease, anxiety was reduced for 2 months after two doses of LSD. In medical settings, no complications of LSD administration were observed. These data should contribute to further investigations of the therapeutic potential of LSD in psychiatry
