Abstract:

Abstract Objectives Within-couple similarities in personality traits tend to be positively associated with relationship well-being. However, research in this area is typically based on cross-sectional designs, thereby limiting examination of longitudinal personality concordance. Given that life experiences shape within-person change in personality, and that partners within a couple often experience similar life events, investigation of within-couple personality synchrony and associations with marital outcomes is warranted. Methods Using data from 3,988 couples (mean age at baseline = 67.0 years, SD = 9.6), multilevel dyadic growth models estimated within-couple similarity in baseline levels, change, and occasion-to-occasion variability for each of the Big Five personality traits over an 8-year follow-up. Bivariate growth models examined the effect of within-couple similarity on perceived spousal support, accounting for dependency within couples. Results Adjusting for baseline age, education, functional ability, and relationship length, analyses revealed within-couple concordance between baseline levels of all 5 personality traits, as well as correlated within-couple fluctuations in neuroticism, extraversion, and openness over time. Similarity in openness, agreeableness, and neuroticism trajectories predicted spousal support. Couples were most similar in openness, showing correlated intercepts, change, and variability, and this longitudinal synchrony was particularly important for perceived spousal support in women. Discussion These findings provide evidence for longitudinal personality synchrony over time within older adult couples. Further, concordance in neuroticism, extraversion, and openness predicted perceived spousal support, though there may be some gender differences in personality dynamics and relationship well-being. Effects of similarity were relatively small compared to actor and partner effects of these traits.

Abstract:

Researchers have suggested that apart from the actual division of household labor, housework ideology and spousal support also influence perceptions of fairness regarding the division of household labor. Furthermore, although only individual perceived fairness predictors are typically examined, researchers acknowledge that an individual’s perceived fairness is often contingent on a combination of characteristics within a couple. In addition to self-perceived fairness, we examined perceptions of fairness for spouse in 104 couples expecting their first child. Results indicate that couple-level actual division of housework and housework ideology significantly predict perceptions of fairness. Furthermore, our data provide evidence to suggest that some predictors’ influence may depend on the level of analysis (couple vs. individual), as well as the type of perceived fairness examined (self vs. spouse). Findings illustrate the importance of considering predictors at the dyadic level, as well as examining self-perceived fairness and spousal perceived fairness as separate constructs.

Abstract:

Research on the implications of varying measurement strategies for estimating levels and correlates of intimate partner violence (IPV) has been limited. This study explored measurement and correlates of IPV using a community sample of 168 couples who were expecting their first child. In line with prior research, couple agreement regarding the presence of violence was low, and maximum reported estimates revealed substantial IPV perpetrated by both expectant mothers and fathers. Different types of IPV scores predicted unique variance in mental health problems and couple relationship distress among both the whole sample and the subsamples who perpetrated any violence. Discussion focuses on the methodological and substantive implications of these findings for the study of IPV during the transition to parenthood.

Abstract:

Couples making the transition to parenthood experience challenges that can threaten the quality and stability of their relationships and the health of family members. Currently, the educational infrastructure to support the delivery of couple-relationship education during the transition to parenthood is limited. Because new-parent couples interact with the health care system at many points during this transition time, an opportunity exists for strengthening couple relationships within the system to improve the well-being of adults and children. In this article, we propose a productive collaboration between marriage/couple educators and health care systems to integrate couple-relationship education into the standard of perinatal care.

Abstract:

The transient two-dimensional natural convective couple stress fluid flow past a semi-infinite vertical flat plate in the presence of first-order homogenous chemical reaction is investigated. The analysis has been carried out by considering the effects of skin-friction coefficient and Nusselt and Sherwood numbers. The unsteady coupled nonlinear governing flow equations have been solved by applying the Crank–Nicolson implicit finite difference scheme. For the different set physical parameters, graphs are shown and examined. A relevant study with existing results is made in a limiting sense. The transient and steady-state velocity profiles decrease as the chemical reaction parameter, Schmidt number, and couple stress parameter increase. The deviations of concentration, temperature, and velocity contours of the couple stress fluid flow are considerably varied in comparison with the Newtonian fluid flow.

Abstract:

The hip joint envisages the prime load bearing structure among other joints in the human body. Hip joint failure leads to the replacement of the hip joint prosthesis. This research work focuses on the proper selection of bearing couple materials for the hip joint to improve the performance and life. Herein, the stress and deformation of different bearing couple materials are analysed in the perspective of transient dynamic analysis under jogging load cycle. Selective hip joint bearing (femoral head-liner) couples are SS316L on UHMWPE (MoP), CoCrMo on UHMWPE (MoP), Ti6Al4V on SrO-ZTA (MoC), SrO-ZTA on UHMWPE (CoP) and SrO-ZTA on SrO-ZTA (CoC) encountered, respectively. The SrO-ZTA on SrO-ZTA (CoC) bearing couple generates the less Von Mises stress of 180.88 MPa. Load bearing pressure and Archard law predict the wear depth of CoCrMo on UHMWPE (MoP) and SrO-ZTA on SrO-ZTA (CoC) bearing couples are 0.141 mm/year and 0.031 mm/year, respectively. In simultaneous, the theoretical wear volume for CoCrMo on UHMWPE (MoP) and SrO-ZTA on SrO-ZTA (CoC) bearing couples are found as 35.46[Formula: see text]mm3/year and 2.62[Formula: see text]mm3/year, respectively. The wear depth and wear volume are supporting the available clinical retrievals and exist in well acceptable range. Competitive wear analysis data ensures 15 years safe life of SrO-ZTA on SrO-ZTA (CoC) hip prosthesis bearing.

Abstract:

This study examined the mediating role of dyadic coping (DC) in the association between internalizing symptoms and dyadic adjustment in a sample of 184 couples expecting their first child. Each partner completed self-report questionnaires assessing symptoms of depression and anxiety, dyadic adjustment and DC during the second trimester of pregnancy. An extension of the actor-partner interdependence model for testing direct and indirect effects was used. Compared to men, women presented higher levels of internalizing symptoms and dyadic adjustment and engaged more in DC by self. Significant indirect effects of internalizing symptoms on dyadic adjustment via common DC and DC by one’s partner were found. Specifically, higher internalizing symptoms were associated with lower common DC and DC by one’s partner, which, in turn, were associated with lower dyadic adjustment. This mediation occurred either within person as well as across partners and occurred similarly for women and men. These results suggest that primiparous couples may benefit from DC-enhancing interventions, such as the cognitive-behavioral couple-based programs Couples Coping Enhancement Training (CCET) and Coping-Oriented Couple Therapy (COCT), to assist them in responding sensitively to their partners’ psychological symptoms, which may have a positive effect on marital adjustment.

Abstract:

We present a systematic and "from the ground up" analysis of the "minimal coupling" type of gauging of Yang–Mills symmetries in (2, 2)-supersymmetric (1+1)-dimensional space–time. Unlike in the familiar (3+1)-dimensional N=1 supersymmetric case, we find several distinct types of minimal coupling symmetry gauging, and so several distinct types of gauge (super)fields, some of which entirely novel. Also, we find that certain (quartoid) constrained superfields can couple to no gauge superfield at all, others (haploid ones) can couple only very selectively, while still others (nonminimal, i.e. linear ones) couple universally to all gauge superfields.

Abstract:

Purpose The predominant narrative is that contemporary organisations, motivated by economic-rationalist aspirations, adopt cloud applications on the premise of achieving cost-savings and efficiency gains. However, how they actually adopt and rollover such new or emerging technologies may be influenced by acts, patterns and processes of institutional legitimacy. Therefore, the purpose of this paper is to explore the dynamics surrounding decisions on how specific cloud applications are adopted from the context of institutional theory, with a particular focus on the concepts of coupling and decoupling. Design/methodology/approach To examine this phenomenon, two qualitative case studies, using a reflexive research approach, of an Australian and a Swedish university have been undertaken, both of which adopted commercial cloud applications for e.g. e-mail, collaboration and storage (as examples of software as a service) at different points in time. One of the universities was known for its early adoption of cloud applications, but had decelerated further deployment of such services, while the other, despite its conservative reputation, has made rapid strides in this regard. Findings The findings of the dual case studies reveal that organisations, contrary to economic-rationalist claims, may or may not decide to adopt particular commercial cloud-based offerings for the support of core operations, on the basis of how they perceive their institutional legitimacy being affected by a complex network of influential actors, both internally and in the external spaces. Therefore, this paper offers an institutional theory-based discourse and rich illustrations on how the role of technology is played out in enhancing relationships between an organisation and such actors in terms of legitimacy focusing acts of coupling and decoupling. Originality/value In the analysis and findings the authors, in a novel way, illustrate how organisations strive for: institutional legitimacy through acts of coupling, and the revelations of consequential decoupling. The value is based on a rich case description, analysis and application of institutional theory.

Abstract:

Informed by the Core and Balance Model of Family Leisure Functioning, we investigated the contribution of one type of family leisure—couple vacations—in enhancing couples’ cohesion and flexibility (i.e., functioning). Studying dyadic data from 112 couples (224 individuals) from across the United States of America, results of multilevel models showed that the variable “shared experiences during vacations” was positively associated with couples’ day-to-day functioning at home. Couples who engaged in higher levels of shared experiences during their vacations, such as effective communication, showing affection, or experiencing new things together, reported higher levels of couple flexibility and cohesion following their vacations, regardless of the number of vacations. We discuss the implications of these results for couples who spend quality time together away from home, as well as future use of our study model when examining benefits of vacationing for families.

Abstract:

This paper investigates couple-group consensus problems for multiagent first-order and second-order systems. Several consensus protocols are proposed based on the time-dependent distributed event-triggered control. For the case of no communication delays, the time-dependent event-triggered strategies are applied to couple-group consensus problems. Based on the matrix theory, algebraic conditions for couple-group consensus are established. For the system with communication delays, based on event-triggered strategies, a Lyapunov-Krasovskii functional is constructed to prove the input-to-state stability of the systems. Moreover, Zeno behavior is excluded. Finally, numeral examples are given to illustrate the effectiveness of these results.

Abstract:

Galvanic properties were evaluated on bare and anodized Ti-1023 titanium alloy which coupled to Ni-electroplated, Zn-electroplated, Cd-electroplated 30CrMnSiA and anodized LY12, respectively. Corrosion properties including open circuit potential (Eoc) of each material, galvanic corrosion potential (Eg), and corrosion current (Ig) of the couples were monitored in conjunction with a Model 263A potentiostat system. Corrosion current density (Īg) and average value of corrosion potential (Ēg) were calculated from Ig-time and Eg-time curves, respectively. Corrosion morphology was observed on a optical microscope (OM) and corrosion mechanisms were analyzed and discussed. The corrosion resistance of Ti-1023/LY12 couple was significantly improved by Ti-1023 anodized coating. However, the coating accelerated the dissolve of the three electroplated coatings in the other galvanic couples, resulting in a heavy corrosion attack on 30CrMnSiA steel.

Abstract:

The incremental diffusion couples are used for evaluating interdiffusion couples in a narrow composition range and these results are extrapolated to get an estimate of impurity diffusion coefficients. In fact, several incremental couples are needed to get impurity diffusion coefficients at different compositions. This process is generally tedious. The present method describes a relatively simple method for evaluating the diffusion coefficients using “step diffusion couples”. A simple experimental method is described to prepare a step diffusion couple. This method involves preparation of diffusion couples in two stages. In the first stage, diffusion couple is made between the two materials in a conventional way and annealed for extended period of time to have a large diffusion zone typically of the order of 2-3 mm. In the second stage, the starting materials are placed on the diffusion couple in a direction perpendicular to the diffusion zone and annealed at a suitable temperature for diffusion to occur between the diffusion zone and the starting materials. This method is applied to study the interdiffusion behavior in the b phase of the Ti-Zr system. Boltzmann-Matano and Hall’s methods were used to determine the interdiffusion coefficients and their composition dependence. Kirkendall shift is observed towards Ti side and the intrinsic diffusion coefficients of Ti is approximately three times that of Zr. The width of the diffusion zone is strongly dependent on the composition of the step diffusion couple. It is observed that the interdiffusion coefficients evaluated at the terminal compositions matched well those published values in the Ti-Zr system. This experimental technique offers an easy and elegant method to determine the diffusion parameters without the tedious preparation of incremental diffusion couples.

Abstract:

Background: The aim of this study was to investigate the association of physical activity (PA) with assisted reproductive technology (ART) treatment and pregnancy outcomes among couples seeking infertility treatment. Methods: This prospective cohort study was carried out among 128 infertile individuals (64 couples), entering the infertility clinic for ART procedures. Baseline PA (before entering any treatment) was assessed using accelerometry for both women and men. For every couple the infertility treatment outcomes were recorded. Results: The couples that required invasive ART procedures such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) spent less time in vigorous PA (−73 min/week per couple, woman + man) than those couples who became spontaneously pregnant after entering the study (p = 0.001). We observed no significant associations between the time spent in physical activities and positive pregnancy test or live birth. Conclusions: Our results do not support a positive nor negative relation between the time the couples spent in physical activities and the chances of getting pregnant or having a baby among patients seeking infertility treatment. However, couples undergoing invasive ART procedures did less vigorous PA than couples that became spontaneously pregnant, suggesting that PA may interfere with their reproductive health.

Abstract:

Abstract With the advance of the gender revolution, income dynamics in couples are changing. Nonetheless, in most Western societies, parenthood still promotes specialized gender roles. Utilizing Norwegian register data on all married and cohabiting couples born 1946–1989, we investigate possible changes in the associations between parenthood and within-couple inequality in earnings in the years 2005–2014. Precisely, using interactions and fixed effects models, we compare the development of within-couple gender gaps in earnings over time between childless couples and couples with children of different ages, and within couples before and after childbirth. Results showed that the gender gap in earnings in couples increased with the number of children and was most distinct among couples with children below 6 years. However, the association between parenthood and within-couple inequality in earnings was reduced across the study period, a development partly driven by a decreasing fatherhood premium evident from 2009 onwards. Not only women’s but also men’s income development is now negatively affected by having young children in the household. Our findings, thus, indicate important changes in how men and women prioritize paid labour after a childbirth.

Abstract:

As suggested by the conservation of resources theory, in contemporary societies time is considered as a limited resource in the same way as money and energy. In the current paper, a novel daily rhythm approach related to motility is presented, in order to highlight the effects of life acceleration on family life management and other professional, leisure, and consumption activities. The analysis is based on a qualitative survey involving 20 families (40 interviewees) that include long-distance commuters living in the suburban areas of Voiron and Thionville in France. These families are composed of an active couple and at least two children under 18 years of age, and the couple commutes at least 60 km every day between home and work. Based on this particularly stressful daily configuration, the qualitative survey deals with the modalities of managing daily time between and within these couples. The quantitative and qualitative analysis of the corpus of interviews shows first, a very high daily rhythm, and second, the diversity of strategies that lead to a typology of resources used to deal with daily time pressures. The results suggest that forms of time-related vulnerabilities depend on social, economic, and temporal resources, while confirming the importance of rhythms analysis in the daily mobility field and in the resource theory.

Abstract:

AbstractThe author argues for a conception of the oedipal complex that excludes the idea of a pre-oedipal phase which, according to him, comes from a confusion with the pre-genital. The author seeks to identify the existence of a “couple object” present early on in the young child whose pre-history he returns to in the first lineaments of a form of “being with”, as in the first form of recording relational models concerning the meeting with the first objects. This matrix will then be made more complex over time and brought into crisis in the “oedipal crisis”, and the way in which the child will be able to meet and go through this crisis, to organize himself and to organize the solutions to the crisis, will configure its model of “oedipal organization”.

Abstract:

Abstract Background Multiple chronic conditions may erode physical functioning, particularly in the context of complex self-management demands and depressive symptoms. Yet, little is known about how discordant conditions (i.e., those with management requirements that are not directly related and increase care complexity) among couples are linked to functional disability. Purpose We evaluated own and partner individual-level discordant conditions (i.e., discordant conditions within individuals) and couple-level discordant conditions (i.e., discordant conditions between spouses), and their links to levels of and change in functional disability. Methods The U.S. sample included 3,991 couples drawn from nine waves (1998–2014) of the Health and Retirement Study. Dyadic growth curve models determined how individual-level and couple-level discordant conditions were linked to functional disability over time, and whether depressive symptoms moderated these links. Models controlled for age, minority status, education, each partner’s baseline depressive symptoms, and each partner’s number of chronic conditions across waves. Results Wives and husbands had higher initial disability when they had their own discordant conditions and when there were couple-level discordant conditions. Husbands also reported higher initial disability when wives had discordant conditions. Wives had a slower rate of increase in disability when there were couple-level discordant conditions. Depressive symptoms moderated links between disability and discordant conditions at the individual and couple levels. Conclusions Discordant chronic conditions within couples have enduring links to disability that partly vary by gender and depressive symptoms. These findings generate valuable information for interventions to maintain the well-being of couples managing complex health challenges.

Abstract:

Galvanic corrosion of Nickel-Chrome alloy (Ni-Cr alloy) and Copper (Cu) coupled in 5% sulfuric acid solution was investigated. The effects of agitation velocity, temperature, and time on the galvanic corrosion current and the weight loss of both metals in both free corrosion and galvanic corrosion were investigated. The trends of open circuit potential (OCP) of each metal and galvanic potential (Eg) of the couple were also determined. The results showed that Cu was cathodic relative to Ni-Cr alloy in galvanic couple and the corrosion potential of the couple (Ni- Cr alloy /Cu) was between the values of the two single components because the OCP of copper shifted to positive with the increase in velocity. Under stagnant conditions initially the galvanic current was more negative then shifted to the positive with time. The corrosion of Ni-Cr alloy decreased with time because the passivation layer was formed on the surface. Under flow conditions, the galvanic current sharply shifted to the negative direction (increase galvanic current from Ni-Cr alloy (anode) to Cu (cathode) during the first few minutes.

Abstract:

Abstract This study examines the accumulation of personal wealth of husbands and wives and investigates the development of within-couple wealth inequalities over time in marriage. Going beyond previous research that mostly studied the marriage wealth premium using household-level wealth data and that conceptualized marriage as an instantaneous transition with uniform consequences over time, we argue that entry into marriage is a gendered life-course event that dynamically shapes husbands’ and wives’ wealth accumulation. Using high-quality data from the German Socio-Economic Panel Study (2002, 2007, 2012, and 2017), we apply fixed-effects regression models to describe wealth accumulation within marriage. We find evidence that wealth premiums are lower during early years of marriage, but increase steadily thereafter. The premium is mostly concentrated in housing wealth. Results from supplementary analyses with limited data, however, suggest that the premium may not be causal for men. Regarding within-couple wealth inequalities, we find a pronounced within-couple wealth gap prior to marriage during pre-marital cohabitation. This gap remains stable over time in marriage. In contrast to findings regarding income, our study indicates that the institution of marriage may not amplify within-couple wealth inequalities further.

Full text

Abstract:

The convention in Western societies of partners sharing a bed is symbolic of their status as a couple, their commitment to the relationship, and their desire for shared intimacy. Yet for many couples, incompatibility as sleeping partners may threaten to undermine romantic notions of the double bed. This paper draws on in-depth interview and audio diary data from research into sleep in couples aged 20-59 (N=40) to examine how couples negotiate the spatial, temporal and relational dimensions of the sleeping environment. The paper contends that the management of tensions inherent in the sleeping relationship plays a key role in framing the couple identity over time, as well as reinforcing the gendered roles, power relationships and inequalities which underpin everyday life.

Abstract:

Although research suggests that stressful marital experiences may lead to feelings of loneliness in later life, little is known about the influence of marital strain over an extended period of time on loneliness in later years. Thus, in the present study, drawing from family systems and cognitive theories along with common fate and actor–partner interdependence modeling approaches, we hypothesized a hybrid model comprised of two multilevel pathways explaining the persistent influence of marital strain on loneliness, including: (a) a couple-level pathway and (b) an individual pathway involving within-spouse and between-spouse effects. Specifically, we investigated the influences of individual- and couple-level trajectories of marital strain over a period of 25 years (from 1991 to 2015) on loneliness outcomes in later years with a sample of 257 couples in enduring, long-term (over 40 years) marriages. The results mostly supported both hypothesized pathways. Consistent with the pathway involving a couple-level process, couple-level trajectories of marital strain predicted couples’ later-life loneliness as reflected by both spouses’ reports of loneliness (shared perceptions). In addition, at the individual level, each spouses’ unexplained variances (unique perception) in marital strain trajectories predicted his/her own later-life loneliness outcomes (within-spouse effect or actor effect). Findings are discussed as they relate to intervention and prevention programs focusing on the well-being of married couples in later life.

Abstract:

AbstractAdverse effects of early exposure to parental mood disturbance on child adjustment have been documented for both mothers and fathers, but are rarely examined in tandem. Other under-researched questions include effects of changes over time in parental well-being, similarities and contrasts between effects of parental mood disturbance on children's internalizing versus externalizing problems, and potential mediating effects of couple relationship quality. The current study involved 438 couples who reported symptoms of depression and anxiety at each of four time points (i.e., last trimester of pregnancy and 4, 14, and 24 months postbirth). Mothers and fathers also rated their couple relationship quality and their child's socioemotional adjustment at 14 months, as well as internalizing and externalizing problems at 24 months. Latent growth models indicated direct effects of (a) maternal prenatal well-being on externalizing problems at 24 months, and (b) paternal prenatal well-being on socioemotional problems at 14 months. Internalizing symptoms at 24 months showed only indirect associations with parental well-being, with couple relationship quality playing a mediating role. Our findings highlight the importance of prenatal exposure to parental mood disturbance and demonstrate that, even in a low-risk sample, poor couple relationship quality explains the intergenerational stability of internalizing problems.

Abstract:

In the current study, the moderating effects of observed negative and positive affects on the association between intimate partner violence (IPV, physical aggression) and relationship satisfaction were examined over a 5-year period. Multiwave data were obtained from a sample of young adult men at risk for delinquency and their women partners (n = 121 couples; ages 21–26 years). The trajectory of each partner’s relationship satisfaction and the effects of dyadic IPV and affect were tested using HLM analyses and a two-level (within-couple and between-couple) dyadic growth model. Average levels of dyadic positive affect were associated with relationship satisfaction for both men and women. For men, increases in couples’ positive affect over time were linked to increases in relationship satisfaction, and increases in couples’ externalizing negative affect were linked to decreases in satisfaction. For women, higher levels of couples’ IPV predicted lower levels of satisfaction. Couples’ internalizing negative affect amplified the effects of IPV on satisfaction over time. Increases in IPV were associated with declines in satisfaction for couples with high levels of internalizing negative affect. Conversely, average levels of externalizing negative affect did not amplify the association between IPV and relationship satisfaction. In fact, the adverse influence of IPV on relationship satisfaction was greater for couples who displayed low levels of externalizing negative affect. Because of the inverse association between externalizing negative affect and relationship satisfaction, these findings were interpreted to suggest that the salience of IPV was greater in couples whose relationship satisfaction was not already impaired by high levels of negative affect.

Abstract:

Sn–In alloys are promising low-melting-point Pb-free solders. Cu and Ni are common substrates in the electronic products. This study examines the interfacial reactions in the Sn–20 at.% In(γ–InSn4)/Cu and Sn–20 at.% In/Ni couples at 160 °C. Only the η–Cu6Sn5 phase layer is formed in the Sn–20 at.% In/Cu couple, and the layer grows thicker with longer reaction time. The reaction path is γ–InSn4/η–Cu6Sn5/Cu. A peculiar phenomenon with the bulging of the couple near the Ni substrate is found in the Sn–20 at.% In/Ni couple. A liquid phase is formed by interfacial reaction in the solid/solid Sn–20 at.% In/Ni couple at 160 °C, and the reaction path is γ–InSn4/liquid/δ–Ni3Sn4 + liquid/(δ–Ni3Sn4)/Ni. Usually Ni has a slower reaction rate with solders; however, the consumption rates of Ni substrate are much higher than those of Cu substrate in this study when they are in contact with the Sn–20 at.% In alloy at 160 °C due to the formation of the liquid phase in the Sn–20 at.% In/Ni couple.

Abstract:

This study aims to determine the processes and problems in arranged marriages, the potential for violence experienced by couples and the pattern of solutions in overcoming the problems of paired couples. The research method used is a qualitative research method with a phenomenological approach. Data collection techniques are using interview techniques. The research used purposive that are chosen based on specific characteristics, namely a maximum age of one year of marriage and marriage to the matched system. This study involved three married couples who were married to the matchmaking system. The results of this study explain that the process of adjustment in an arranged marriage partner has different periods, from the data in the field of adjustment on the groom's shorter period is different from the period on the bride who needs a long time in adjustment. The adjustment process involved is not only on both sides but also the family, and the environment also contributes to the adjustment process. The couple adjusts to a way to stay in excellent communication, open, mutual respect, maintain the feelings of the couple, respect and discuss to solve the problems faced and finally the couple managed to adjust well.

Abstract:

By choosing appropriate annealing temperature and annealing time, diffusion couples made of aluminum bronze and tool materials were prepared to simulate the diffusion and phase formation during the actual machining. These results were compared to those obtained from turning experiments. In agreement with results obtained from diffusion couple experiments, all turning experiments showed that major elements in both tool materials and workpiece diffused into their counterparts. The diffusion of C away from the tool will reduce the tool strength. It is helpful to use diffusion couple results to comprehend the diffusion effect in the actual turning process.

A configuration with four attracting masses in the determination of Newtonian gravitational constant G by the time-of-swing method is proposed. One couple of attracting masses is put in the outer space of the two attracted masses and another couple one is put in the inner space. Because the signals of the two couples of attracted masses will be superposed while the noises due to the uncertainty of the attracted masses separation will be compensated. There exists an optimum separation between the attracted masses, in which the requirement of measuring this separation can be reduced by a factor of about 400.

Abstract:

In this paper, the weighted couple-group consensus of continuous-time heterogeneous multiagent systems with input and communication time delay is investigated. A novel weighted couple-group consensus protocol based on cooperation and competition interaction is designed, which can relax the in-degree balance condition. By using graph theory, general Nyquist criterion and Gerschgorin disc theorem, the time delay upper limit that the system may allow is obtained. The conclusions indicate that there is no relationship between weighted couple-group consensus and communication time delay. When the agents input time delay, the coupling weight between the agents, and the systems control parameters are satisfied, the multiagent system can converge to any given weighted coupling group consistent state. The experimental simulation results verify the correctness of the conclusion.

A de-couple control method with information feedback from other control channel and a method with double control loops were present for the hypersonic vehicle with non-linear, couple and lateral maneuver. The whole controller was divided into two parts: the computation of actuator which deal with control couple and design of control law which solve the problem of movement and aerodynamic couple. The time-varying controller parameter method and robust control law were present to solve the problem of quick time-varying model parameter and non-linear. Finally these two methods were analyzed contrastively; the simulation result show that these two methods present above can achieve the quick dynamic and high precise track of command.

Abstract:

The stress on couples who have a child die is tremendous. Fourteen couples who had a short or long preparation time for their child's death were interviewed. All parents expressed guilt. It was also discovered that because of this grief and the accompanying guilt, sexual intercourse was performed only by three couples within the first three days after the death, with sexual guilt occurring with one couple. Hugging and being held, however, became a comforting behavior found in all but one couple. This behavior was a new experience for the men. Although sex was perceived as undesirable, it was again initiated for a specific reason: to produce a replacement child. Although the literature indicates that replacement children could be potentially pathological, the question arises whether a replacement child could be a “normal” need for parents of childbearing years.

Abstract:

On 30 June 2016, the European Court of Human Rights (hereafter ‘European Court’) decided that a binational same-sex couple was discriminated against because they were not allowed to marry; and at the same time, they were unable to live in Italy as a couple. For nearly one decade, human rights non-governmental organizations (NGOs) have submitted third-party interventions asking the European Court to recognize that unmarried same-sex couples should be treated differently from unmarried different sex couples when the first have no possibility of marrying. This article argues that the European Court has finally accepted what the NGOs have suggested since 2007, and that the decision in Taddeucci and McCall v. Italy signals a positive step forward from the ‘analogous situation’ doctrine towards recognizing indirect discrimination on the grounds of sexual orientation for same-sex couples.

Abstract:

The COVID-19 pandemic and confinement, as a measure to stop the contagion, have had a strong impact on the mental health of the population. Emotions such as uncertainty, fear of contracting illness and anguish have increased. But, also, positive experiences have emerged that reinforce interdependence and social support, the appreciation of affections and a greater connection and reflection on the way of life. The objective of this article is to delve into the experience of some couples who have been able to constructively face quarantine and who express a positive assessment of what this time of confinement has contributed to their relationship. Three dimensions are identified in which resources have emerged during this crisis: family reorganization and multiplicity of roles, the appreciation of support networks and the strengthening of intimacy in the couple.

Abstract:

Purpose The purpose of this paper is to explore if an expatriate’s career situation at the level of the couple (single career couple (SCC)/dual career couple (DCC)) is related to the expatriate’s work-to-personal-life conflict (WLC) and if the expatriate’s gender is related to WLC. The authors also investigate if the level of WLC is different for men and women in a DCC or SCC (interaction). Design/methodology/approach The study was conducted among 393 Finnish expatriates who were in a relationship and were working. A moderated hierarchical regression was utilized in the data analysis. Findings Gender or DCC/SCC status was not separately related to WLC but an interaction effect between gender and a couple’s career status on WLC was significant. In DCC couples, women experienced more WLC than men. In SCC couples, women experienced less WLC than men. Practical implications The findings indicate that organizations should develop practices to support both DCCs and SCCs, for instance, by providing mentors for expatriates and their family members, or through organizing family events for company employees. Couples should also negotiate their roles and responsibilities in both the personal life and work-life spheres before moving abroad and also during the time they live abroad, especially women involved in a DCC and men involved in an SCC. Originality/value This is the first study focusing on expatriates’ WLC that simultaneously takes account of how the gender and career situation of the couple are related to it.

Abstract:

Objective and background: The present study tested whether the similarity levels of relationship-oriented values among Chinese couples would be higher than those among randomly matched male–female pairs. Furthermore, we examined whether couple similarity of relationship-oriented values would predict spouses’ marital satisfaction and life satisfaction above the actor and partner effects of relationship-oriented values over time and the potential marriage cohort differences. Method: Data were retrieved from the China Family Panel Studies data set in 2010–2014. Our study included a nationally representative sample of 10,860 first-married couples who provided data on relationship-oriented values, marital satisfaction, and life satisfaction. Results: The average profile similarity on relationship-oriented values of the real couples was higher than that of the randomly matched male–female pseudo couples. Actor–Partner Interdependence Model analyses showed that (1) couple similarity of relationship-oriented values was positively associated with husbands’ and wives’ life satisfaction indirectly through wives’ marital satisfaction among couples with short to medium marital duration, even after controlling for life satisfaction 4 years ago and a set of sociodemographic variables; (2) husbands’ relationship-oriented values were positively associated with couples’ life satisfaction indirectly through husbands’ marital satisfaction among couples with short to medium and long marital duration. Conclusion: With a large dyadic sample of Chinese couples, our findings expand the literature on the significant role of couple similarity of relationship-oriented values in personal and relational well-being.

Abstract:

AbstractA method for investigating the pure squeeze action in an isothermal elastohydrodynamically lubrication (EHL) problem, i.e., circular contacts lubricated with couple stress fluid, was developed. A constant load condition was used in the calculations. The initial conditions such as pressure profiles, normal squeeze velocities, and film shapes were obtained from the classical hydrodynamic lubrication theory at a specified large central film thickness. The coupled transient modified Reynolds, elasticity deformation, and load equilibrium equations are solved simultaneously. The simulation results reveal that the effect of the couple stress is equivalent to enhancing the lubricant viscosity, thus enlarging the film thickness. The effect of couple stress in thin film lubrication varies with film size. That is, the thinner the lubricating film is, the more obvious the effect of couple stress is. For larger characteristic length, materials parameter, and load, the central pressure, central film thickness, and rigid separation are larger than those of smaller characteristic length under the same load. The time needed to achieve maximum central pressure and the Hertzian pressure increases with increasing characteristic length.

Abstract:

Marriage is one of young adulthood’s developmental task. The beginning phase of marriage is often beyond expectation of the newlyweds, it is a hard adjustment time for the couples. Therefore, adjustment in this phase is crucial for future marriage quality. The aim of this research is to describe the dyadic adjustment of young adult couples in the beginning phase of their marriage, using Spanier’s dimension of dyadic adjustment. This reasearch use qualitative approach with interview and observation as data collection method. This research found that in dyadic consensus, one couple see a disagreement because of different way of thinking. In dyadic cohesion, one couple feel that they are lack of intimacy. In dyadic satisfaction, the couples tend to feel satisfied. While in affectional expression, the couples tend to express affection thruouh physical contact and behaviour that accord with their couple’s preference. Areas that could be improved are couple’s communication to reach dyadic concensus and couple’s intimacy to increase dyadic cohession.
