Social behavior effects of diphenyl dimethyl bicarboxylate (DDB) in the sensory contact model

Sensory contact model (SCM) permits the evolution of diverse psychopathological states by the repeated antagonistic interactions between male mice. Biphenyl dimethyl dicarboxylate (DDB) is used as a hepatoprotective agent. The present work aimed to study the possible effects of DDB on social behavior developed by SCM by studying its effects on the transformation process to aggressive and submissive behaviors. Besides, measuring behavioral changes using the open field test (OFT) and the elevated plus maze test (EPM), neurochemical parameters [serotonin (5HT), norepqinephrine (NE), and dopamine(DA)], and immunological changes (total leucocyte count, differential leucocytic count, and evaluation of bone marrow lymphocytes count and viability assessment). Adult male Swiss mice were used; DDB was given in a dose of 100mg/kg by oral gavage daily for 2weeks from the fifth day to the last day of the SCM. The present study concluded that administration of DDB to the SCM involved animals was shown to be associated with significant positive impacts on the behavior of depressed partner in the SCM which were manifested by decreased latency and increased ambulation and rearing in OFT, increased number of entry in the open arm/total no of entries in EPM. This was associated with changes in brain levels of neurotransmitters which were manifested by increased NE and decreased DA, as well as the examined immunity related parameters which were manifested by increased total leucocyte count, bone marrow lymphocytes, and monocytes. So DDB can be used as a supportive antidepressant agent in patients with liver impairment and should be avoided in aggressive ones. However, more randomized controlled trials should be carried out to ascertain these effects.

Boundary spanner relational behavior and inter-organizational control in supply chain relationships

Boundary spanner relational behavior is considered critical in the successful management of buyer–supplier relationships and may help avoiding high costs of more formal inter-organizational controls. Yet, the influence of partners' boundary spanners on effective supply chain collaboration has had much less inquiry than the influence of broader inter-organizational controls. We use survey data of 200 buyer–supplier relationships to examine how these individual and organizational control mechanisms influence the performance effects of interfirm collaborations that vary in scope of activities undertaken. Findings show that collaboration scope as well as boundary spanner relational behavior and inter-organizational controls are positively associated with performance. The effect of collaboration scope on firm performance, however, also depends on both mechanisms but in opposite directions: while its influence on performance is enhanced by inter-organizational controls, relational behavior of partners' boundary spanners has a negative moderating effect, indicating that such behavior contributes more to the effective management of collaborations of narrow scope than those of broader scope.

Health Behaviors of Student Community Research Partners When Designing and Implementing a Healthy Lifestyle Intervention on College Campuses.

Few studies work with college students as equal partners in all aspects of Community-Based Participatory Research (CBPR) and even less evaluate behaviors of those college partners. The current study aimed to examine health behaviors of students by designing and implementing a peer-led, social marketing campaign (Get Fruved) to promote healthier lifestyles on their campuses. Enrolled students (n = 376) were trained to either design and implement a health promotion intervention (Social Marketing and Environmental Interventionists; SMEI, n = 78), be peer mentors (PM; n = 205), or serve as control participants (n = 93). Students’ behaviors (dietary, activity, and stress) and anthropometrics were assessed at baseline, 6 months, and 12 months. The population was predominately Caucasian, female, and between 19 and 20 years old. On average, fruit and vegetable consumption slightly decreased across all time points for each group with control at a larger decline. Students International Physical Activity Questionnaire (IPAQ) scores showed students met recommended amounts of activity throughout the intervention, with males reporting higher activity levels. Cohen’s Perceived Stress Scale (PSS) analyses indicated 19 year olds had higher stress along with females had higher than males. Students involved in a CBPR approach to be trained, design, and implement a lifestyle intervention can achieve maintenance of health behaviors throughout a college year when compared to control students.

A new way to look at an old problem: International joint venture partner selection via constrained systematic search

Although international joint ventures (IJVs) provide many benefits to multinational enterprises (MNEs), IJVs continue experiencing high dissolution rates; there is a pressing need to re-evaluate the partner selection process for IJVs. In this article, I utilize constrained systematic search (CSS) as the proposed process by which to improve the partner selection process and reduce IJV dissolution rates. CSS is a process MNEs can utilize to gain private information about potential IJV partners. The implementation of CSS can improve the success rates for an MNE entering an IJV in two ways: MNEs can more effectively identify (1) information withholding/misleading behavior of potential partners and (2) complementary resources in potential partners.

Effects of Informal Contracts on Innovative Cooperation among Enterprises in Industrial Clusters: An Evolutionary Game Analysis

Industrial cluster theory has important guiding significance for regional industrial development and industrial agglomeration advantages. Cooperation among enterprises is the corner stone of industrial clusters. The purpose of the paper is to explore the effects of cluster informal contracts on cluster enterprises and the behavior of external partners. Based on the dynamic evolutionary game theory, this paper constructs a model, which incorporates several main factors influencing the innovative cooperation among local and external cluster enterprises. By calculating the replicator dynamics equations and analyzing the evolutionary stable strategies, this paper discusses the evolution process of cooperation strategies of enterprises in different situation. Furthermore, by using MATLAB software to simulate the model, this paper verifies the accuracy and reliability of the game model. Results show that, in addition to the formal market contract, effective implementations of cluster informal contracts can reduce opportunistic behavior in innovative cooperation among internal and external enterprises. Meanwhile, we should pay attention to strengthen the external innovative cooperation, increase severity of penalties, enhance the credit network externality, and avoid the relevant risks. The paper enriches our understanding about how informal contracts can help promote and cultivate good cooperative order in innovative cooperation of clusters.

Sexual behavior and sexually transmitted diseases among the female partners of inmates.

ABSTRACTObjective:to analyze the sexual behavior of the female partners of inmates and estimate the prevalence of sexually transmitted diseases. Method:cross-sectional, quantitative study involving 349 female partners of inmates. The Estudo de Comportamento Sexual [Sexual Behavior Study], an instrument validated in Brazil, was used to collect the data. The Statistical Package for the Social Sciences, version 20 was used in the statistical analysis. Results:41.2% of the female partners of inmates reported a prior history of sexually transmitted disease. Association was found between having more than one partner in the last 12 months (<0.006), sexual violence (<0.001), having sex for money (<0.001), under the influence of alcohol (<0.001), and under the influence of drugs (<0.005). The variables associated with sexually transmitted infections in the logistic regression were: having more than one partner in the last 12 months, sexual violence, sex for money, and under the effect of alcohol or drugs. Conclusion:The number of partners, sexual violence, sex for money, and under the influence of alcohol or drugs are sexual risk behaviors that increase the prevalence of sexually transmitted infections among the female partners of inmates.

Links Between Communication and Relationship Satisfaction Among Patients With Cancer and Their Spouses: Results of a Fourteen-Day Smartphone-Based Ecological Momentary Assessment Study.

Cancer treatment poses significant challenges not just for those diagnosed with the disease but also for their intimate partners. Evidence suggests that couples' communication plays a major role in the adjustment of both individuals and in the quality of their relationship. Most descriptive studies linking communication to adjustment have relied on traditional questionnaire methodologies and cross-sectional designs, limiting external validity and discernment of temporal patterns. Using the systemic-transactional model of dyadic coping as a framework, we examined intra- and inter-personal associations between communication (both enacted and perceived) and relationship satisfaction (RS) among patients with stage II–IV breast or colorectal cancer and their spouses (N = 107 couples). Participants (mean age = 51, 64.5% female patients, and 37.4% female spouses) independently completed twice-daily ecological momentary assessments (EMA) via smartphone for 14 consecutive days. Items assessed RS and communication (expression of feelings, holding back from expression, support and criticism of partner, and parallel ratings of partner behavior). Linear mixed models employing an Actor Partner Interdependence Model were used to examine concurrent, time-lagged, and cross-lagged associations between communication and RS. Expressing one's feelings was unassociated with RS. Holding back from doing so, in contrast, was associated with lower RS for both patients and spouses in concurrent models. These effects were both intrapersonal and interpersonal, meaning that when individuals held back from expressing their feelings, they reported lower RS and so too did their partner. Giving and receiving support were associated with one's own higher RS for both patients and spouses in concurrent models, and for patients in lagged models. Conversely, criticizing one's partner and feeling criticized were maladaptive, associated with lower RS (own and in some cases, partner's). Cross-lagged analyses (evening RS to next-day afternoon communication) yielded virtually no effects, suggesting that communication may have a stronger influence on short-term RS than the reverse. Findings underscore the importance of responsive communication, more so than expression per se, in explaining both concurrent and later relationship adjustment. In addition, a focus on holding back from expressing feelings may enhance the understanding of RS for couples coping with cancer.

PFIs involving multiple public partners: a case study from the Italian healthcare sector

The financial crisis experienced by many countries since 2008 has given new importance to private finance initiatives (PFIs) for providing public services. This paper analyses the relationships between multiple public and private sector actors participating in a PFI in the healthcare sector in order to better understand the motives and behaviour of public and private sector partners. High levels of trust and the active participation of a regulatory body were found to be significant factors in terms of creating a partnership that benefits all sides.

Decay behavior of the strange and beauty partners of Pc hadronic molecules

We extend our previous study on the decay behavior of Pc hadronic molecules to their strange and beauty partners. While Pc(4380) and Pc(4450) locate just below the D¯Σc⁎ and D¯⁎Σc thresholds, respectively, their proposed strange partners N(1875) and N(2080) sit just below the KΣ⁎ and K⁎Σ thresholds, respectively. Using the effective Lagrangian approach as the same as for the study of Pc hadronic molecular states and with the couplings determined by the SU(3) flavor symmetry, the decay patterns of N(1875) and N(2080) are obtained assuming them to be the S-wave KΣ⁎ and K⁎Σ molecules, respectively. It is found that the measured decay properties of N(1875) and N(2080) are reproduced well. Our results suggest that both N(1875) and N(2080) can be described as the hadronic molecular pentaquark states in the hidden strangeness sector with quantum number I(JP)=1/2(3/2−). Further checks on their hadronic molecule nature by various experiments are proposed. With the same approach, we also give our predictions for the decay behavior of the possible beauty partners of the Pc hadronic molecular states. The B⁎Λb is found to be the largest decay mode for both BΣb⁎ and B⁎Σb hadronic molecules, hence can be used to look for the hidden beauty pentaquark states in forthcoming experiments.

Quantitative Matching of Clutch Size in Reciprocating Hermaphroditic Worms

Reciprocity [1] is one of the most controversial evolutionary explanations of cooperation among non-kin [2, 3]. For some authors, cognitive capacity of non-human organisms is limiting, and more parsimonious mechanisms should apply [3-5]; for others, the debate is mainly semantic [2, 6], and empirical evidence can be found in a wide range of taxa [7]. However, while the ability to alternate cooperative behaviors does not settle the reciprocity controversy, the capacity to adjust cooperative behavior to the value of received help could prove decisive. Marine polychaete worms Ophryotrocha diadema, as several simultaneous hermaphrodites, do not self-fertilize and have unilateral mating (i.e., they behave either as females or as males during each mating event). They are also external fertilizers and thus cannot store allosperm, which contribute to make them ideal model organisms to investigate reciprocity, since partners usually alternate sexual roles with each other, repeatedly exchanging egg clutch of variable size [8-12]. However, whether the alternation of sexual roles is the result of conditional reciprocity rather than by-product reciprocity has never been tested [13]. Here, we show that O.diadema worms reciprocate eggs conditionally to the partner's behavior and adjust the quality of cooperation according to that of their partners. Moreover, only egg reciprocation offers similar fitness returns via both the female and the male function with respect to non-reciprocating laying strategies. These results document that fine-tuned forms of conditional reciprocity can emerge in cognitively unsophisticated animals, broadening the criteria to recognize conditional reciprocity among animals.

Who are the male sexual partners of adolescent girls and young women? Comparative analysis of population data in three settings prior to DREAMS roll-out.

BackgroundThe DREAMS (Determined Resilient Empowered AIDS-free, Mentored and Safe) Partnership aims to reduce HIV incidence among adolescent girls and young women (AGYW,15-24y) with a core package of evidence-based interventions. Some interventions, including voluntary HIV counselling and testing and circumcision, will be targeted at the male sexual partners of AGYW. A priority of DREAMS is to characterise the male partners for effective targeting.MethodsUsing population-based data (2010–2015) in three DREAMS impact evaluation settings in Kenya and South Africa, we describe the demographic characteristics and sexual behaviour of male partners reported by AGYW, and the characteristics of males who report sexual activity with AGYW.ResultsIn all settings, over 90% of recent male partners reported by AGYW were aged <35 years. Median ages of spousal and non-spousal partners were 29 and 23 years respectively in uMkhanyakude (rural South Africa) and 21 and 20 years respectively in Nairobi (urban Kenya). Most males reporting an AGYW partner had never been married (89%) and many were in school (39%). Most male partners reported only 1 AGYW partner in the past year; in Gem (rural Kenya) and Nairobi 25%-29% reported 2+(AGYW or older female) partners. Concurrent partners were reported by 16% of male partners in Gem and 3–4% in uMkhanyakude. Two thirds of male partners in Gem reported testing for HIV in the past 6 months and under half in uMkhanyakude reported testing for HIV in the past year. Almost all (96%) partners in Nairobi were circumcised, compared to 45% in Gem and 43% in uMkhanyakude.ConclusionsWith almost all AGYW’s sexual partners aged 15–34 years, this is an appropriate target group for DREAMS interventions. Encouraging young men to reduce their number of partners and concurrency, and uptake prevention and treatment services such as HIV testing, circumcision and ART is crucial in the effort to reduce HIV among both AGYW and young men.

Who are the male partners of adolescent girls and young women in Swaziland? Analysis of survey data from community venues across 19 DREAMS districts.

BackgroundAdolescent girls and young women (AGYW, ages 15–24) are at high risk of HIV in Swaziland. Understanding more about their male sexual partners can inform HIV prevention efforts for both.MethodsUsing the PLACE methodology across all 19 DREAMS implementation districts, 843 men ages 20–34 were surveyed between December 2016-February 2017. Surveys were conducted at 182 venues identified by community informants as places where AGYW and men meet/socialize. Descriptive and multivariate analyses examined characteristics and risk behaviors of male partners of AGYW.ResultsMen’s average age was 25.7. Sixty-three percent reported female partners ages 15–19, and 70% reported partners ages 20–24 in the last year; of those, 12% and 11% respectively had five or more such partners. Among the 568 male partners of AGYW, 36% reported consistent condom use with their current/last partner. Forty-two percent reported testing for HIV in the last year; 6% were HIV-positive, and of those, 97% were currently on treatment. One-third (37%) reported being circumcised; among uncircumcised, 81% were not considering it. In multivariate analyses, men who reported three or more AGYW partners in the last year were more likely to be HIV-positive (aOR 3.2, 95% CI 1.1,8.8). Men were also less likely to disclose their HIV status to adolescent versus older partners (aOR 0.6, 95% CI 0.4,0.9) and partners more than 5 years younger than themselves (aOR 0.6, 95% CI 0.4,0.9). Results also revealed relatively high unemployment and mobility, substantial financial responsibilities, and periodic homelessness.ConclusionsMost men identified through community venues reported relationships with AGYW, and these relationships demonstrated substantial HIV risk. Challenging life circumstances suggest structural factors may underlie some risk behaviors. Engaging men in HIV prevention and targeted health services is critical, and informant-identified community venues are promising intervention sites to reach high-risk male partners of AGYW.

Bacterial Sexuality at the Nanoscale.

Understanding the basic mechanisms of bacterial sexuality is an important topic in current microbiology and biotechnology. While classical methods used to study gene transfer provide information on whole cell populations, nanotechnologies offer new opportunities for analyzing the behavior of individual mating partners. We introduce an innovative atomic force microscopy (AFM) platform to study and mechanically control DNA transfer between single bacteria, focusing on the large conjugative pXO16 plasmid of the Gram-positive bacterium Bacillus thuringiensis. We demonstrate that the adhesion forces between single donor and recipient cells are very strong (∼2 nN). Using a mutant plasmid, we find that these high forces are mediated by a pXO16 aggregation locus that contains two large surface protein genes. Notably, we also show that AFM can be used to mechanically induce plasmid transfer between single partners, revealing that transfer is very fast (<15 min) and triggers major cell surface changes in transconjugant cells. We anticipate that the single-cell technology developed here will enable researchers to mechanically control gene transfer among a wide range of Gram-positive and Gram-negative bacterial species and to understand the molecular forces involved. Also, the method could be useful in nanomedicine for the design of antiadhesion compounds capable of preventing intimate cell-cell contacts, therefore providing a means to control the resistance and virulence of bacterial pathogens.

Environment-adaptive interaction primitives through visual context for human\u2013robot motor skill learning

In situations where robots need to closely co-operate with human partners, consideration of the task combined with partner observation maintains robustness when partner behavior is erratic or ambiguous. This paper documents our approach to capture human–robot interactive skills by combining their demonstrative data with additional environmental parameters automatically derived from observation of task context without the need for heuristic assignment, as an extension to overcome shortcomings of the interaction primitives framework. These parameters reduce the partner observation period required before suitable robot motion can commence, while also enabling success in cases where partner observation alone was inadequate for planning actions suited to the task. Validation in a collaborative object covering exercise with a humanoid robot demonstrate the robustness of our environment-adaptive interaction primitives, when augmented with parameters directly drawn from visual data of the task scene.

Male partners of young women in Uganda: Understanding their relationships and use of HIV testing.

BackgroundSubstantial concern exists about the high risk of sexually transmitted HIV to adolescent girls and young women (AGYW, ages 15–24) in Eastern and Southern Africa. Yet limited research has been conducted with AGYW’s male sexual partners regarding their perspectives on relationships and strategies for mitigating HIV risk. We sought to fill this gap in order to inform the DREAMS Partnership and similar HIV prevention programs in Uganda.MethodsWe conducted 94 in-depth interviews, from April-June 2017, with male partners of AGYW in three districts: Gulu, Mukono, and Sembabule. Men were recruited at community venues identified as potential transmission areas, and via female partners enrolled in DREAMS. Analyses focused on men’s current and recent partnerships and HIV service use.ResultsMost respondents (80%) were married and 28 years old on average. Men saw partner concurrency as pervasive, and half described their own current multiple partners. Having married in their early 20s, over time most men continued to seek out AGYW as new partners, regardless of their own age. Relationships were highly fluid, with casual short-term partnerships becoming more formalized, and more formalized partnerships characterized by periods of separation and outside partnerships. Nearly all men reported recent HIV testing and described testing at distinct relationship points (e.g., when deciding to continue a relationship/get married, or when reuniting with a partner after a separation). Testing often stemmed from distrust of partner behavior, and an HIV-negative status served to validate respondents’ current relationship practices.ConclusionsAcross the three regions in Uganda, findings with partners of AGYW confirm earlier reports in Uganda of multiple concurrent partnerships, and demonstrate substantial HIV testing. Yet they also unearth the degree to which these partnerships are fluid (switching between casual and/or more long-term partnerships), which complicates potential HIV prevention strategies. Context-specific findings around these partnerships and risk are critical to further tailor HIV prevention programs.

I hear but I don't see you: Interacting over phone reduces the accuracy of perceiving affiliation in the other

In-person interactions are characterized by better psychological and interpersonal outcomes than technology-mediated interactions. These benefits are thought to stem from the presence of more communication channels for the expression and reception of affiliative cues and the effortless processing of these cues. We investigated whether in-person versus phone-mediated interactions are characterized by higher accuracy of perceiving the other's affiliation and higher bias of assumed similarity with this other regarding affiliation. Using an event-contingent recording methodology, cohabitating romantic partners reported their perception of the other's affiliative behavior and their affiliative behavior in interactions with each other during a 20-day interval. Participants during in-person interactions (1) were more accurate in perceiving affiliative behavior and (2) assumed greater similarity between their own and their partner's affiliative behavior. Findings suggest that greater accuracy in perceiving affiliation and assumption of similarity with the romantic partner with respect to affiliation may in part explain the benefits of in-person interactions.

Avoidant romantic attachment in adolescence: Gender, excessive internet use and romantic relationship engagement effects.

Romantic development is a distinctive characteristic of puberty. However, a significant proportion of adolescents present with avoidant romantic attachment (ARA) tendencies, which have significant impact on their general adaptation. ARA variations have been suggested in relation to age, gender, engagement with a romantic partner and Excessive Internet Use (EIU) behaviours. In this longitudinal, two-wave study of a normative sample of 515 Greek adolescents at 16 and 18 years, ARA was assessed with the relevant subscale of the Experiences in Close Relationships-Revised and EIU with the Internet Addiction Test. A three-level hierarchical linear model found ARA tendencies to decrease between 16 and 18 while engagement in a romantic relationship and EIU were associated with lower and higher ARA tendencies respectively. Gender did not differentiate ARA severity either at the age of 16 or its changes over time. Results highlight the need of adopting a longitudinal-contextualized approach and provide implications for prevention and intervention initiatives in relation to the romantic development of adolescents.

Expanding and Validating a Typology of Intimate Partner Violence: Intersections of Violence and Control Within Relationships.

This research explored an expanded typology of intimate partner violence (IPV), intersecting violent and controlling behaviors of partners. Secondary data were analyzed ( n = 714). Cluster analyses indicated that elements of IPV (control perpetration, control victimization, violence victimization, and violence perpetration) all clustered in high/low patterns, which intersected to form 10 unique categories of IPV. Support for all of Johnson's categories of IPV was found, but there was also evidence for the three control-related categories: Unidirectional Control, Bidirectional Control, and Control Resistance. This expanded typology can move research, practice, and policies beyond the gender symmetry debate.

Prevalence and factors associated with syphilis, HIV and hepatitis B virus infections among men who have sex with men in Togo in 2017

Introduction Hepatitis B and other sexually transmitted infections (STIs) have been linked to an increased risk of HIV transmission and disease progression among men who have sex with men (MSM), but their frequency and distribution in this community have not been extensively studied in Togo. In addition, a holistic understanding of transmission patterns of these STIs is required in order to develop sustainable prevention strategies and reduce transmission among MSM. The objective of the study was to estimate the prevalence and factors associated with syphilis, HIV and hepatitis B virus (HBV) infections among men who have sex with men (MSM) in Togo in 2017. Method A cross-sectional study was conducted in eight main cities in Togo from August 1 to September 30, 2017. MSM aged 18 years and above were recruited using the respondent driven sampling method. Data including socio-demographic characteristics, human immunodeficiency virus (HIV) testing history, condom use patterns, sexual partners characteristics and behaviors were collected using a questionnaire during face-to-face interviews. Blood samples were drawn after the interview for STIs screening using rapid tests. Multivariate logistic regression analyses were performed to identify factors associated with syphilis, HBV and HIV infections among MSM. Results Out of a total of 711 MSM recruited, 69.7% were living in Lome, which is the capital city of Togo. Median age of study participants was 23 years, interquartile range (21–27 years) and 91.4% had at least secondary education level. At least three MSM over ten reported having condomless anal sex during the last month. The prevalence of syphilis, HIV, and HBV infection among 678 (95.3%) MSM who accepted the screening test was 0.0% [upper limit of 95% confidence interval (95% CI) 0.9%], 21.9% (95% CI [18.9–25.3%]), and 7.1% (95% CI [5.3–9.3%]), respectively. Among them, 7 (1.0%) (95% CI [0.4–2.2]) had HIV and HBV co-infection. The prevalence of HBV infection was not associated with HIV infection status (4.7% among MSM infected with HIV and 7.8% among MSM not infected with HIV, P = 0.199). Age, place of residency, nationality, MSM membership, previous HIV screening, and living with a male partner were significantly associated with HIV infection (P Conclusion Our findings emphasize the importance of targeting HIV and viral hepatitis testing and prevention efforts to populations at risk for STIs. Despite all the awareness campaigns, the prevalence of STIs among MSM remains high. This urges the implementation of routine screening, vaccine-based prevention, and education programs for this most-at-risk population.
