Cohabitation with a romantic partner has become common in recent decades. This meta-analysis examined the link between premarital cohabitation and marital stability (k = 16) and marital quality (k = 12). Cohabitation had a significant negative association with both marital stability and marital quality. The negative predictive effect on marital stability, however, did not remain when only cohabitation with the eventual marital partner was analyzed, suggesting that these cohabitors may attach more long-term meaning to living together. Moderator analyses demonstrated that effects of cohabitation have remained consistent over time, despite the fact that cohabitation has become more normative.

In the context of bone fractures, the influence of the mechanical environment on the healing outcome is widely accepted, while its influence at the cellular level is still poorly understood. This study explores the influence of mechanical load on naïve mesenchymal stem cell (MSC) differentiation, focusing on hypertrophic chondrocyte differentiation. Unlike primary bone healing, which involves the direct differentiation of MSCs into bone-forming cells, endochondral ossification uses an intermediate cartilage template that remodels into bone. A high-throughput uniaxial bioreactor system (StrainBot) was used to apply varying percentages of strain on naïve MSCs encapsulated in GelMa hydrogels. This research shows that cyclic uniaxial compression alone directs naïve MSCs towards a hypertrophic chondrocyte phenotype. This was demonstrated by increased cell volumes and reduced glycosaminoglycan (GAG) production, along with an elevated expression of hypertrophic markers such as MMP13 and Type X collagen. In contrast, Type II collagen, typically associated with resting chondrocytes, was poorly detected under mechanical loading alone conditions. The addition of chondrogenic factor TGFβ1 in the culture medium altered these outcomes. TGFβ1 induced chondrogenic differentiation, as indicated by higher GAG/DNA production and Type II collagen expression, overshadowing the effect of mechanical loading. This suggests that, under mechanical strain, hypertrophic differentiation is hindered by TGFβ1, while chondrogenesis is promoted. Biochemical analyses further confirmed these findings. Mechanical deformation alone led to a larger cell size and a more rounded cell morphology characteristic of hypertrophic chondrocytes, while lower GAG and proteoglycan production was observed. Immunohistology staining corroborated the gene expression data, showing increased Type X collagen with mechanical strain. Overall, this study indicates that mechanical loading alone drives naïve MSCs towards a hypertrophic chondrocyte differentiation path. These insights underscore the critical role of mechanical forces in MSC differentiation and have significant implications for bone healing, regenerative medicine strategies and rehabilitation protocols.

Today, more corporations disclose information about their environmental performance in response to stakeholder demands of environmental responsibility and accountability. What information do corporations disclose on their websites? This paper investigates the environmental management policies and practices of the 200 largest corporations in the world. Based on a content analysis of the environmental reports of Fortune's Global 200 companies, this research analyzes the content of corporate environmental disclosures with respect to the following seven areas: environmental planning considerations, top management support to the institutionalization of environmental concerns, environmental structures and organizing specifics, environmental leadership activities, environmental control, external validations or certifications of environmental programs, and forms of corporate environmental disclosures.

Peripartum individuals with substance misuse are a high-risk population that challenge clinicians and child welfare specialists alike. Federal legislation was updated in 2016 with the Comprehensive Addiction Recovery Act (CARA) to improve care via expanded screening and treatment referrals for peripartum women with substance misuse. The implementation of CARA requires providers to update their policies and procedures in order to meet the requirements outlined by this legislation. As this is a new process, this paper reviews the new administrative reporting and safety planning requirements relevant to obstetrical care providers and provides examples of best practice for different clinical scenarios. Given the variable state laws, confidentiality concerns, influence of stigma and health inequities on substance use treatment, and the fragmented healthcare system, implementation of CARA will challenge obstetric, pediatric, and mental health care providers along with child welfare services. All entities involved must work together to create effective and efficient protocols to address the CARA requirements. Health systems must also evaluate and update methods and interventions to assure that policies improve family stability and well-being.

This study tests a model of physical aggression in a sample of 194 men being treated for physical or psychological aggression in the greater Madrid area of Spain. The prevalence of aggression in this sample was lower than in a US batterer sample. In the path model highlighted here, borderline personality traits and alcohol problems were identified as risk factors for physical aggression perpetration and the role of borderline traits was mediated by psychological aggression. A reciprocal relationship was found between psychological perpetration and victimization but not physical perpetration and victimization. These findings are discussed within a cross-cultural context; conceptual and treatment implications are also addressed.

Corporate America is institutionalizing ethics through a variety of structures, systems, and processes. This study sought to identify managerial perceptions regarding the institutionalization of ethics in organizations. Eighty-six corporate-level marketing and human resource managers of American multinational corporations responded to a mail survey regarding the various implicit and explicit ways by which corporations institutionalize ethics. The results revealed that managers found ethics to be good for the bottom line of the organizations, that they did not perceive the need for additional formalization of ethics, and that they perceived implicit forms of institutionalizing ethics (e.g., leadership, corporate culture, top management support) to be more effective than the explicit forms of institutionalizing ethics (e.g., ethics officers, ethics committees, ethics newsletters). Implications of the survey and future research directions conclude the paper.

Despite the amount of research on partner aggression, the field lacks a unified theory. Personality problems, substance use, marital distress, and psychological aggression are consistently included in models of physical aggression but these variables have not been incorporated into one concise model with a strong theoretical rationale. We hypothesize that psychopathic traits, borderline traits, and alcohol use problems are each risk factors for psychological aggression and physical aggression during relationship conflict. We also hypothesize that borderline traits suggest poorer relationship quality due to the interpersonal difficulties central to Borderline Personality Disorder, which in turn is a risk factor for greater psychological aggression. Finally, we suggest that psychological aggression is likely to escalate into physical aggression regardless of the associated psychopathology. This study tests a model of physical aggression in a sample of 194 men in treatment for physical or psychological aggression in the Madrid area of Spain. Results suggest the prevalence of aggression in this Spanish batterer sample is lower than in batterer samples in the US. In the path model highlighted in this paper, borderline traits were risk factors for poor relationship quality, psychological and physical aggression perpetration, and alcohol problems. Alcohol problems were associated with physical aggression. Psychological aggression and alcohol problems significantly mediated the association between borderline traits and physical aggression. These findings are discussed within a culture-sensitive context and we also address conceptual and treatment implications.
