We analysed observations from 31 neighbourhood parks, with each park mapped into smaller target areas for study, across five US cities generated using the System for Observing Play and Recreation in the Community (SOPARC). In areas where at least two people were observed, less than one-third (31.6%) were populated with at least one white and one non-white person. Park areas that were supervised, had one or more people engaged in vigorous activity, had at least one male and one female present, and had one or more teens present were significantly more likely to involve interracial groups (p<0.01 for each association). Observations in parks located in interracial neighbourhoods were also more likely to involve interracial groups (p<0.05). Neighbourhood poverty rate had a significant and negative relationship with the presence of interracial groups, particularly in neighbourhoods that are predominantly non-white. Additional research is needed to confirm the impact of these interactions. Urban planning and public health practitioners should consider the health benefits of interracial contact in the design and programming of neighbourhood parks.

We explore the existence and underlying neural mechanism of a new norm endorsed by both black and white Americans for managing interracial interactions: "racial paralysis', the tendency to opt out of decisions involving members of different races. We show that people are more willing to make choices--such as who is more intelligent, or who is more polite-between two white individuals (same-race decisions) than between a white and a black individual (cross-race decisions), a tendency which was evident more when judgments involved traits related to black stereotypes. We use functional magnetic resonance imaging to examine the mechanisms underlying racial paralysis, to examine the mechanisms underlying racial paralysis, revealing greater recruitment of brain regions implicated in socially appropriate behavior (ventromedial prefrontal cortex), conflict detection (anterior cingulate cortex), deliberative processing (dorsolateral prefrontal cortex), and inhibition (ventrolateral prefrontal cortex). We also discuss the impact of racial paralysis on the quality of interracial relations.

Perspective taking combats automatic expressions of racial bias.

Todd, Andrew R; Bodenhausen, Galen V; Richeson, Jennifer A; Galinsky, Adam D

2011-06-01

Five experiments investigated the hypothesis that perspective taking--actively contemplating others' psychological experiences--attenuates automatic expressions of racial bias. Across the first 3 experiments, participants who adopted the perspective of a Black target in an initial context subsequently exhibited more positive automatic interracial evaluations, with changes in automatic evaluations mediating the effect of perspective taking on more deliberate interracial evaluations. Furthermore, unlike other bias-reduction strategies, the interracial positivity resulting from perspective taking was accompanied by increased salience of racial inequalities (Experiment 3). Perspective taking also produced stronger approach-oriented action tendencies toward Blacks (but not Whites; Experiment 4). A final experiment revealed that face-to-face interactions with perspective takers were rated more positively by Black interaction partners than were interactions with nonperspective takers--a relationship that was mediated by perspective takers' increased approach-oriented nonverbal behaviors (as rated by objective, third-party observers). These findings indicate that perspective taking can combat automatic expressions of racial biases without simultaneously decreasing sensitivity to ongoing racial disparities. 2011 APA, all rights reserved

Is love colorblind? Political orientation and interracial romantic desire.

PubMed

Eastwick, Paul W; Richeson, Jennifer A; Son, Deborah; Finkel, Eli J

2009-09-01

The present research examined the association of political orientation with ingroup favoritism in two live romantic contexts. In Study 1, White participants had sequential interactions with both a White and Black confederate and reported their romantic desire for each. In Study 2, both White and Black participants speed-dated multiple potential romantic partners and reported whether they would be interested in meeting each speed-dating partner again. In both studies, White participants' political conservatism positively predicted the strength of the ingroup-favoring bias: White conservatives were less likely than White liberals to desire Black (interracial) relative to White potential romantic partners. In contrast, Black participants' political conservatism negatively predicted the strength of the ingroup-favoring bias: Consistent with system-justification theory, Black conservatives were more likely than Black liberals to desire White (interracial) relative to Black potential romantic partners. Political orientation may be a key factor that influences the initiation of interracial romantic relationships.

Circulating angiogenic cell function is inhibited by cortisol in vitro and associated with psychological stress and cortisol in vivo.

2016-05-01

Psychological stress and glucocorticoids are associated with heightened cardiovascular disease risk. We investigated whether stress or cortisol would be associated with reduced circulating angiogenic cell (CAC) function, an index of impaired vascular repair. We hypothesized that minority-race individuals who experience threat in interracial interactions would exhibit reduced CAC function, and that this link might be explained by cortisol. To test this experimentally, we recruited 106 African American participants for a laboratory interracial interaction task, in which they received socially evaluative feedback from Caucasian confederates. On a separate day, a subset of 32 participants (mean age=26years, 47% female) enrolled in a separate biological substudy and provided blood samples for CAC isolation and salivary samples to quantify the morning peak in cortisol (the cortisol awakening response, CAR). CAC function was quantified using cell culture assays of migration to vascular endothelial growth factor (VEGF) and secretion of VEGF into the culture medium. Heightened threat in response to an interracial interaction and trait anxiety in vivo were both associated with poorer CAC migratory function in vitro. Further, threat and poorer sustained attention during the interracial interaction were associated with a higher CAR, which in turn, was related to lower CAC sensitivity to glucocorticoids. In vitro, higher doses of cortisol impaired CAC migratory function and VEGF protein secretion. The glucocorticoid receptor antagonist RU486 reversed this functional impairment. These data identify a novel, neuroendocrine pathway by which psychological stress may reduce CAC function, with potential implications for cardiovascular health. Copyright © 2016 Elsevier Ltd.

A Little Similarity Goes a Long Way: The Effects of Peripheral but Self-Revealing Similarities on Improving and Sustaining Interracial Relationships

West, Tessa V.; Magee, Joe C.; Gordon, Sarah H.; Gullett, Lindy

2017-01-01

Integrating theory on close relationships and intergroup relations, we construct a manipulation of similarity that we demonstrate can improve interracial interactions across different settings. We find that manipulating perceptions of similarity on self-revealing attributes that are peripheral to the interaction improves interactions in cross-race dyads and racially diverse task groups. In a getting-acquainted context, we demonstrate that the belief that one’s different-race partner is similar to oneself on self-revealing, peripheral attributes leads to less anticipatory anxiety than the belief that one’s partner is similar on peripheral, nonself-revealing attributes. In another dyadic context, we explore the range of benefits that perceptions of peripheral, self-revealing similarity can bring to different-race interaction partners and find (a) less anxiety during interaction, (b) greater interest in sustained contact with one’s partner, and (c) stronger accuracy in perceptions of one’s partners’ relationship intentions. By contrast, participants in same-race interactions were largely unaffected by these manipulations of perceived similarity. Our final experiment shows that among small task groups composed of racially diverse individuals, those whose members perceive peripheral, self-revealing similarity perform superior to those who perceive dissimilarity. Implications for using this approach to improve interracial interactions across different goal-driven contexts are discussed. PMID:24956315

Interracial roommate relationships: negotiating daily interactions.

PubMed

Trail, Thomas E; Shelton, J Nicole; West, Tessa V

2009-06-01

Jobs, social group memberships, or living arrangements lead many people to interact every day with another person from a different racial background. Given that research has shown that interracial interactions are often stressful, it is important to know how these daily interactions unfold across time and what factors contribute to the success or failure of these interactions. Both members of same-race and mixed-race college roommate pairs completed daily questionnaires measuring their emotional experiences and their perceptions of their roommate. Results revealed that roommates in mixed-race dyads experienced less positive emotions and intimacy toward their roommates than did roommates in same-race dyads and that the experience of positive emotions declined over time for ethnic minority students with White roommates. Mediation analyses showed that the negative effects of roommate race were mediated by the level of intimacy-building behaviors performed by the roommate. Implications for future research and university policies are discussed.

Education and black-white interracial marriage.

PubMed

Gullickson, Aaron

2006-11-01

This article examines competing theoretical claims regarding how an individual's education will affect his or her likelihood of interracial marriage. I demonstrate that prior models of interracial marriage have failed to adequately distinguish the joint and marginal effects of education on interracial marriage and present a model capable of distinguishing these effects. I test this model on black-white interracial marriages using 1980, 1990, and 2000 U.S. census data. The results reveal partial support for status exchange theory within black male-white female unions and strong isolation of lower-class blacks from the interracial marriage market. Structural assimilation theory is not supported because the educational attainment of whites is not related in any consistent fashion to the likelihood of interracial marriage. The strong isolation of lower-class blacks from the interracial marriage market has gone unnoticed in prior research because of the failure of prior methods to distinguish joint and marginal effects.

The Joint Effect of Bias Awareness and Self-Reported Prejudice on Intergroup Anxiety and Intentions for Intergroup Contact

Perry, Sylvia P.; Dovidio, John F.; Murphy, Mary C.; van Ryn, Michelle

2015-01-01

Two correlational studies investigated the joint effect of Bias Awareness—a new individual difference measure that assesses Whites’ awareness and concern about their propensity to be biased—and prejudice on Whites’ intergroup anxiety and intended intergroup contact. Using a community sample (Study 1), we found the predicted Bias Awareness × Prejudice interaction. Prejudice was more strongly related to interracial anxiety among those high (vs. low) in Bias Awareness. Study 2 investigated potential behavioral consequences in an important real world context: medical students’ intentions for working primarily with minority patients. Study 2 replicated the Bias Awareness × Prejudice interaction and further demonstrated that interracial anxiety mediated medical students’ intentions to work with minority populations. PMID:25111552

Ebony and Ivory?:Interracial Dating Intentions and Behaviors of Disadvantaged African American Women in Kentucky

Luke, David J.; Oser, Carrie B.

2015-01-01

Using data from 595 predominantly disadvantaged African American women in Kentucky, this study examines perceptions about racial/ethnic partner availability, cultural mistrust, and racism as correlates of interracial dating intentions and behaviors with both white and Hispanic men. Participants reported levels of dating intentions and behaviors were significantly higher with whites than Hispanics. The multivariate models indicate less cultural mistrust and believing it is easier to find a man of that racial/ethnic category were associated with higher interracial dating intentions. Women were more likely to have dated a white man if they believed it was easier to find a white man and had interracial dating intentions; however, interracial dating intentions was the only significant correlate of having dated a Hispanic man. Findings suggest a shrinking social distance between racial groups, broadening the MMPI for African American women; yet, the low levels of interracial relationships are likely driven by preferences of men.

Structural effect of size on interracial friendship

PubMed Central

Cheng, Siwei; Xie, Yu

2013-01-01

Social contexts exert structural effects on individuals’ social relationships, including interracial friendships. In this study, we posit that, net of group composition, total context size has a distinct effect on interracial friendship. Under the assumptions of (i) maximization of preference in choosing a friend, (ii) multidimensionality of preference, and (iii) preference for same-race friends, we conducted analyses using microsimulation that yielded three main findings. First, increased context size decreases the likelihood of forming an interracial friendship. Second, the size effect increases with the number of preference dimensions. Third, the size effect is diluted by noise, i.e., the random component affecting friendship formation. Analysis of actual friendship data among 4,745 American high school students yielded results consistent with the main conclusion that increased context size promotes racial segregation and discourages interracial friendship.

Reducing negative affect and increasing rapport improve interracial mentorship outcomes

Ayduk, Özlem; Boykin, C. Malik; Mendoza-Denton, Rodolfo

2018-01-01

Research suggests that interracial mentoring relationships are strained by negative affect and low rapport. As such, it stands to reason that strategies that decrease negative affect and increase rapport should improve these relationships. However, previous research has not tested this possibility. In video-chats (Studies 1 and 2) and face-to-face meetings (Study 3), we manipulated the degree of mutual self-disclosure between mentees and mentors, a strategy that has been shown to reduce negative affect and increase rapport. We then measured negative affect and rapport as mediators, and mentee performance (quality of speech delivered; Studies 1 and 3) and mentor performance (warmth and helpfulness; Studies 2 and 3) as key outcomes. Results revealed that increased self-disclosure decreased negative affect and increased rapport for both mentees and mentors. Among mentees, decreased negative affect predicted better performance (Studies 1 and 3). Among mentors, increased rapport predicted warmer feedback (Studies 2 and 3). These effects remained significant when we meta-analyzed data across studies (Study 4), and also revealed the relationship of rapport to more helpful feedback. Findings suggest that affect and rapport are key features in facilitating positive outcomes in interracial mentoring relationships. PMID:29617368

The intercultural and interracial therapeutic relationship: challenges and recommendations.

PubMed

Qureshi, Adil; Collazos, Francisco

2011-01-01

Although research has demonstrated that mental health services function with patients from different cultural backgrounds, a variety of culture- and race-related factors can result in services being of lower quality than that which occurs when the clinician and patient are from the same culture. The provision of culturally competent care requires many institutional and organizational adaptations that lie beyond the control of most mental health professionals. The therapeutic relationship, however, remains a key factor of mental healthcare that can be attended to by individual therapists. The therapeutic relationship plays an important role in almost every therapeutic approach, and has been increasingly recognized as representing a means to the provision of quality intercultural and interracial treatment. At the same time, a host of cultural and racial factors relating to both the patient and clinician can compromise the development of the therapeutic relationship. This paper will explore some of the key issues that complicate therapeutic contact and communication, and will outline means by which to strengthen key components of the therapeutic relationship.

How couples manage interracial and intercultural differences: implications for clinical practice.

This study focused on how couples managed their interracial and intercultural differences. To understand their experiences, a qualitative grounded theory analysis was used (n=17). Analysis revealed that couples experienced most issues as cultural issues; race only occurred during their interactions with "others." They appeared to organize their responses according to four relationship structures: Integrated, Singularly Assimilated, Coexisting, and Unresolved. Couples in each of these structures managed daily process through four sets of relationship strategies: (a) creating a "we," (b) framing differences, (c) emotional maintenance, and (d) positioning in relationship to familial and societal context. These findings are a step toward a strength-based and research-informed education and clinical interventions for this population.

2011-06-01

The purpose of this study was to examine the "lived experience" of Asian Indian (AI)-White couples in interracial marriages. Ten highly educated AI-White professional couples were individually interviewed about their subjective experience of being in an interracial marriage, the challenges and strengths of this marriage, and the potential role of culture in their marriages. Data were analyzed using the Consensual Qualitative Research methodology. Results indicated that the couples' marital experiences were influenced by a complex intersection of ecosystemic factors with significant psychological impacts. These findings highlight shortcomings in drawing simplistic conclusions regarding the success or failure of an interracial marriage and have important implications for theory, research, and clinical practice. 2011 © FPI, Inc.

Racially diverse classrooms: effects of classroom racial composition on interracial peer relationships.

Barth, Joan M; McDonald, Kristina L; Lochman, John E; Boxmeyer, Carolyn; Powell, Nicole; Dillon, Casey; Sallee, Meghann

2013-01-01

The purpose of this study was to examine the interactive effects that a child's race and the racial composition of a classroom have on a variety of sociometric measures. Sociometric nominations were collected from 872 fifth-grade students (48% male, 48% Black) who were in classrooms that ranged from nearly all Black to nearly all White students. Hierarchical Linear Modeling analyses indicated that the race of the child, the race of the rater, and the classroom race composition each impacted sociometric nominations. Results suggest that schools that are more balanced in the distribution of Black and White students might promote more positive interracial peer relationships. However, opportunities to be highly liked and to be perceived as a leader might be greatest in a school in which the child is in the clear racial majority. © 2013 American Orthopsychiatric Association.

A Perceptual Pathway to Bias: Interracial Exposure Reduces Abrupt Shifts in Real-Time Race Perception That Predict Mixed-Race Bias.

PubMed

Freeman, Jonathan B; Pauker, Kristin; Sanchez, Diana T

2016-04-01

In two national samples, we examined the influence of interracial exposure in one's local environment on the dynamic process underlying race perception and its evaluative consequences. Using a mouse-tracking paradigm, we found in Study 1 that White individuals with low interracial exposure exhibited a unique effect of abrupt, unstable White-Black category shifting during real-time perception of mixed-race faces, consistent with predictions from a neural-dynamic model of social categorization and computational simulations. In Study 2, this shifting effect was replicated and shown to predict a trust bias against mixed-race individuals and to mediate the effect of low interracial exposure on that trust bias. Taken together, the findings demonstrate that interracial exposure shapes the dynamics through which racial categories activate and resolve during real-time perceptions, and these initial perceptual dynamics, in turn, may help drive evaluative biases against mixed-race individuals. Thus, lower-level perceptual aspects of encounters with racial ambiguity may serve as a foundation for mixed-race prejudice. © The Author(s) 2016.

'A Change of Heart': Racial Politics, Scientific Metaphor and Coverage of 1968 Interracial Heart Transplants in the African American Press.

PubMed

Koretzky, Maya Overby

2017-05-01

This paper explores the African American response to an interracial heart transplant in 1968 through a close reading of the black newspaper press. This methodological approach provides a window into African American perceptions of physiological difference between the races, or lack thereof, as it pertained to both personal identity and race politics. Coverage of the first interracial heart transplant, which occurred in apartheid South Africa, was multifaceted. Newspapers lauded the transplant as evidence of physiological race equality while simultaneously mobilising the language of differing 'black' and 'white' hearts to critique racist politics through the metaphor of a 'change of heart'. While interracial transplant created the opportunity for such political commentary, its material reality-potential exploitation of black bodies for white gain-was increasingly a cause for concern, especially after a contentious heart transplant from a black to a white man in May 1968 in the American South.

Family identity: black-white interracial family health experience.

PubMed

Byrd, Marcia Marie; Garwick, Ann Williams

2006-02-01

The purpose of this interpretive descriptive study was to describe how eight Black-White couples with school-aged children constructed their interracial family identity through developmental transitions and interpreted race to their children. Within and across-case data analytic strategies were used to identify commonalities and variations in how Black men and White women in couple relationships formed their family identities over time. Coming together was the core theme described by the Black-White couples as they negotiated the process of forming a family identity. Four major tasks in the construction of interracial family identity emerged: (a) understanding and resolving family of origin chaos and turmoil, (b) transcending Black-White racial history, (c) articulating the interracial family's racial standpoint, and (d) explaining race to biracial children across the developmental stages. The findings guide family nurses in promoting family identity formation as a component of family health within the nurse-family partnership with Black-White mixed-race families.

‘A Change of Heart’: Racial Politics, Scientific Metaphor and Coverage of 1968 Interracial Heart Transplants in the African American Press

PubMed Central

Koretzky, Maya Overby

2017-01-01

Abstract This paper explores the African American response to an interracial heart transplant in 1968 through a close reading of the black newspaper press. This methodological approach provides a window into African American perceptions of physiological difference between the races, or lack thereof, as it pertained to both personal identity and race politics. Coverage of the first interracial heart transplant, which occurred in apartheid South Africa, was multifaceted. Newspapers lauded the transplant as evidence of physiological race equality while simultaneously mobilising the language of differing ‘black’ and ‘white’ hearts to critique racist politics through the metaphor of a ‘change of heart’. While interracial transplant created the opportunity for such political commentary, its material reality—potential exploitation of black bodies for white gain—was increasingly a cause for concern, especially after a contentious heart transplant from a black to a white man in May 1968 in the American South.

A facial attractiveness account of gender asymmetries in interracial marriage.

PubMed

Lewis, Michael B

2012-01-01

In the US and UK, more Black men are married to White women than vice versa and there are more White men married to Asian women than vice versa. Models of interracial marriage, based on the exchange of racial status for other capital, cannot explain these asymmetries. A new explanation is offered based on the relative perceived facial attractiveness of the different race-by-gender groups. This explanation was tested using a survey of perceived facial attractiveness. This found that Black males are perceived as more attractive than White or East Asian males whereas among females, it is the East Asians that are perceived as most attractive on average. Incorporating these attractiveness patterns into the model of marriage decisions produces asymmetries in interracial marriage similar to those in the observed data in terms of direction and relative size. This model does not require differences in status between races nor different strategies based on gender. Predictions are also generated regarding the relative attractiveness of those engaging in interracial marriage.

Relationship stigma and relationship outcomes in interracial and same-sex relationships: Examination of sources and buffers.

PubMed

Rosenthal, Lisa; Starks, Tyrel J

2015-12-01

Interracial and same-sex romantic relationships are more common and socially accepted in the United States than ever before; yet, stigmatization of these relationships persists, with consequences for relationship dynamics. We conducted an online survey study with adults living in the United States in interracial and same-sex relationships to examine associations of relationship stigma from family, friends, and public with several relationship outcomes (i.e., investment, satisfaction, intimate partner aggression victimization and perpetration, commitment, intimacy, trust, passion, love, sexual communication, and sexual satisfaction), as well as the potential buffering roles of egalitarianism and dyadic coping. Regression analyses with 480 participants support that above and beyond individually experienced discrimination and other well-known predictors of relationship outcomes, relationship stigma from friends in particular was associated with lower relationship commitment, trust, love, and sexual communication, as well as greater odds of intimate partner aggression victimization. Egalitarianism and dyadic coping moderated some of the associations of relationship stigma from family, friends, and public with relationship outcomes, supporting their potential roles as buffers. These findings suggest many avenues for future research and implications for clinicians working with interracial and same-sex couples, individuals in those couples, and their families. Given increasing prevalence of interracial and same-sex relationships and marriages, more work should continue to explore these couples' experiences and how best to support them.

A Dyadic Analysis of Relationships and Health: Does Couple-Level Context Condition Partner Effects?

PubMed Central

Barr, Ashley B.; Simons, Ronald L.

2014-01-01

Adding to the growing literature explicating the links between romantic relationships and health, this study examined how both couple-level characteristics, particularly union type (e.g. dating, cohabiting, or marriage) and interracial pairing, and interpersonal characteristics (e.g. partner strain and support) predicted young adults’ physical and mental health. Using dyadic data from a sample of 249 young, primarily African American couples, we hypothesized and found support for the importance of couple-level context, partner behavior, and their interaction in predicting health. Interracial couples (all Black/non-Black pairings) reported worse health than monoracial Black couples. Union type, however, did not directly predict health but was a significant moderator of partner strain. That is, the negative association between partner strain and self-reported health was stronger for cohabiting and married couples versus their dating counterparts, suggesting that coresidence more so than marital status may be important for understanding partner effects on physical health. For psychological distress, however, partner support proved equally beneficial across union types. PMID:25090254

Effects of racism on perceptions and punishment of intra- and interracial crimes.

Saucier, Donald A; Hockett, Jericho M; Zanotti, Danielle C; Heffel, Sarah

2010-10-01

The majority of hate crimes in the United States are driven by racial bias. However, extra-legal factors such as the perpetrators' motivations, the races of the victims and perpetrators, and the presence or absence of hate symbols or slurs often result in ambiguity in the classification of crimes as hate crimes. This uncertainty evokes consideration of how such crimes are characterized and of how violent intra- and interracial crimes are perceived and responded to. The current study used violent crime vignettes to explore the effects of participants' levels of racism, perpetrator and victim race, and assault severity on perceptions of crimes as "hate crimes," victim blame, and sentence recommendations. These results contribute to the understanding of how intra- and interracial crimes are perceived and how individuals' levels of racism affect these perceptions.

Denial of service to same-sex and interracial couples: Evidence from a national survey experiment.

PubMed

Powell, Brian; Schnabel, Landon; Apgar, Lauren

2017-12-01

Legislatures and courts are debating whether businesses can deny services to same-sex couples for religious reasons. Yet, little is known about public views on this issue. In a national survey experiment, Americans ( n = 2035) responded to an experimental vignette describing a gay or interracial couple refused service. Vignettes varied the reason for refusal (religion/nonreligious) and by business type (individual/corporation). Results confirm greater support of service refusal by the self-employed than by corporations and to gay couples than to interracial couples. However, religious reasons for refusal to gay couples elicit no more support than do nonreligious reasons. In the first national study to experimentally analyze views on service refusal to sexual minorities, we demonstrate that views vary by several factors but not by whether the refusal was for religious reasons.

Interracial relationships in Canada have increased over the years. However, little research has focused on comparing STI/HIV risk and condom use between those in intra- and interracial relationships, specifically among Middle Eastern-Canadians. A web-based survey was administered to Middle Eastern-Canadians. Logistic regression analysis was used to assess factors associated with consistent condom use. Analyses were stratified by partner's race (Middle Eastern or non-Middle Eastern). The analysis sub-sample consisted of 92 participants. Factors associated with consistent condom use varied between the stratified groups. Among those with Middle Eastern partners, attitude towards marriage and the family and control in the relationship were associated with condom use. Among participants with non-Middle Eastern partners, acculturation and HIV knowledge were found to be associated with condom use. Factors associated with condom use varied between Middle Eastern-Canadians in intra- and interracial relationships. These differences illustrate the need for tailored interventions aimed at increasing condom use among this racial group.

Stereotype threat is the unpleasant psychological experience of confronting negative stereotypes about race, ethnicity, gender, sexual orientation, or social status. Hundreds of published studies show how the experience of stereotype threat can impair intellectual functioning and interfere with test and school performance. Numerous published interventions derived from this research have improved the performance and motivation of individuals targeted by low-ability stereotypes. Stereotype threat theory and research provide a useful lens for understanding and reducing the negative health consequences of interracial interactions for African Americans and members of similarly stigmatized minority groups. Here we summarize the educational outcomes of stereotype threat and examine the implications of stereotype threat for health and health-related behaviors.

Brain Network Activity During Face Perception: The Impact of Perceptual Familiarity and Individual Differences in Childhood Experience.

PubMed

Cloutier, Jasmin; Li, Tianyi; Mišic, Bratislav; Correll, Joshua; Berman, Marc G

2017-09-01

An extended distributed network of brain regions supports face perception. Face familiarity influences activity in brain regions involved in this network, but the impact of perceptual familiarity on this network has never been directly assessed with the use of partial least squares analysis. In the present work, we use this multivariate statistical analysis to examine how face-processing systems are differentially recruited by characteristics of the targets (i.e. perceptual familiarity and race) and of the perceivers (i.e. childhood interracial contact). Novel faces were found to preferentially recruit a large distributed face-processing network compared with perceptually familiar faces. Additionally, increased interracial contact during childhood led to decreased recruitment of distributed brain networks previously implicated in face perception, salience detection, and social cognition. Current results provide a novel perspective on the impact of cross-race exposure, suggesting that interracial contact early in life may dramatically shape the neural substrates of face perception generally. © The Author 2016.

Gendered races: implications for interracial marriage, leadership selection, and athletic participation.

PubMed

Galinsky, Adam D; Hall, Erika V; Cuddy, Amy J C

2013-04-01

Six studies explored the overlap between racial and gender stereotypes, and the consequences of this overlap for interracial dating, leadership selection, and athletic participation. Two initial studies captured the explicit and implicit gender content of racial stereotypes: Compared with the White stereotype, the Asian stereotype was more feminine, whereas the Black stereotype was more masculine. Study 3 found that heterosexual White men had a romantic preference for Asians over Blacks and that heterosexual White women had a romantic preference for Blacks over Asians; preferences for masculinity versus femininity mediated participants' attraction to Blacks relative to Asians. The pattern of romantic preferences observed in Study 3 was replicated in Study 4, an analysis of the data on interracial marriages from the 2000 U.S. Census. Study 5 showed that Blacks were more likely and Asians less likely than Whites to be selected for a masculine leadership position. In Study 6, an analysis of college athletics showed that Blacks were more heavily represented in more masculine sports, relative to Asians. These studies demonstrate that the gender content of racial stereotypes has important real-world consequences.

I was being myself but being an actor too: the experience of a Black male in interracial psychotherapy.

PubMed

Qureshi, Adil

2007-12-01

In recent years, investigators have indicated that the psychotherapy process is of considerable importance in the context of interracial psychotherapy. Despite the interest in the area, minimal research has examined how racial difference impacts the psychotherapy process. This study examines the lived experience of interracial psychodynamic psychotherapy via an in-depth interview with an African-American man who had been in therapy with a European American therapist. This qualitative study utilizes a hermeneutic phenomenological approach, which accepts that understanding is contingent on both sociohistorical situatedness and relational dynamics. The study participant was chosen because of his interest in the area and willingness to explore it in detail with the interviewer. A number of themes emerged, the most salient of which are the multidimensionality of the experience and the 'absent presence' of race in the therapy process. This client's experience was both positive and negative, and in many cases, the same process-related variables contributed both positively and negatively to the client's therapeutic experience. Issues of trust, perceived cultural issues and therapy focus contributed to and detracted from the therapy experience. The depth of the therapy experience was limited by the therapist not explicitly addressing race.

Othering Processes and STS Curricula: From Nineteenth Century Scientific Discourse on Interracial Competition and Racial Extinction to Othering in Biomedical Technosciences

NASA Astrophysics Data System (ADS)

Arteaga, Juan Manuel Sánchez; El-Hani, Charbel N.

2012-05-01

This paper analyzes the debates on "interracial competition" and "racial extinction" in the biological discourse on human evolution during the second half of the nineteenth century. Our intention is to discuss the ideological function of these biological concepts as tools for the naturalization and scientific legitimation of racial hierarchies during that period. We argue that the examination of these scientific discussions about race from a historical perspective can play the role of a critical platform for students and teachers to think about the role of science in current othering processes, such as those related to biomedical technosciences. If they learn how biological ideas played an ideological function concerning interracial relationships in the past, they can be compelled to ask which ideological functions the biological knowledge they are teaching and learning might play now. If this is properly balanced, they can eventually both value scientific knowledge for its contributions and have a critical appraisal of some of its implications. We propose, here, a number of initial design principles for the construction of teaching sequences about scientific racism and science-technology-society relationships, yet to be empirically tested by iterative cycles of implementation in basic education and teacher education classrooms.

The costume of Shangri-La: thoughts on white privilege, cultural appropriation, and anti-asian racism.

PubMed

Kleisath, C Michelle

2014-01-01

This piece poses cultural appropriation as an undertheorized aspect of white privilege in White Privilege Studies. By way of narrative exploration, it asserts that a paucity of scholarship on Orientalism and anti-Asian racism has created a gap in White Privilege Studies that curbs its radical transformative potential. It argues for the value of a structural and historically focused lens for understanding the issue of cultural appropriation, and extends questions of culture and race relations beyond the borders of the United States. It also explores the complex ways that interracial and transnational relationships can influence white racial identity, and illustrates the disruptive potential that queer interracial relationships can offer to dominant historical patterns of white behavior.

Selected correlates of white nursing students' attitudes toward black American patients.

PubMed

Morgan, B S

1983-01-01

Multivariate analyses were used to examine the relationships between white nursing students' attitudes toward black American patients and variables selected within a theoretical framework of prejudice which included socialization factors and personality-based factors. The variables selected were: authoritarianism and self-esteem (personality-based factors), parents' attitudes toward black Americans, peer attitudes toward black Americans, interracial contact and socioeconomic status (socialization factors). The study also examined the differences in the relationship among white nursing students enrolled in baccalaureate degree, associate degree and diploma nursing programs. Data were collected from 201 senior nursing students enrolled in the three types of nursing programs in Rhode Island during the late fall and winter of 1979-1980. Although baccalaureate degree, associate degree and diploma students were similar in terms of peer attitudes toward black Americans, fathers' attitudes toward black Americans, self-esteem and attitudes toward black American patients, they were significantly different in terms of age, socioeconomic status, mothers' attitudes toward black Americans, interracial contact and authoritarianism. The major findings of this study indicate that the socialization explanation of prejudice is more significant than the personality-based explanation. The variables socioeconomic status, interracial contact and peer attitudes toward black Americans (all socialization variables) accounted for 22.0% of the total variance in attitudes toward black American patients for the total sample of nursing students. However, this relationship was not generalizable across the three different types of nursing programs.

Across racial/ethnic boundaries: investigating intimate violence within a national sample.

PubMed

Carbone-Lopez, Kristin

2013-01-01

The number of interracial relationships in the United States continues to increase. The fact is, though, that race remains a significant influence in the lives of individuals and in their relationships. Although there is evidence that relationships that cross racial/ethnic boundaries may be at greater risk for conflict and dissolution, there have been few investigations as to whether such relationships are at greater risk for violence. Using data from the National Violence Against Women Survey, I find that there are differences in risk of intimate violence depending on the racial/ethnic dyad of the couple. Ethnic monoracial relationships demonstrate the greatest risk for physical and nonphysical forms of violence, controlling for structural factors, whereas women in interracial relationships report higher rates of nonphysical violence, as compared with women in White monoracial relationships. Implications for theory and practice are discussed.

The sexual erotic market as an analytical framework for understanding erotic-affective exchanges in interracial sexually intimate and affective relationships.

PubMed

Vigoya, Mara Viveros

2015-01-01

This paper examines the way in which erotic-affective exchanges in interracial relationships have been analysed in Latin America. It considers how race, gender and class operate within a market of values such that erotic, affective and economic status are shaped by racial, gender and class hierarchies. In this paper I analyse historical and social arrangements that embody the region's political economy of race and sex. Such a perspective allows me to address the simultaneous co-existence of socio-racial exclusion and inclusion and the repressive and productive effects of power, attraction and anxiety as aspects of lived experiences in relation to sexuality. From there, I outline an analytical framework that references an erotic or pleasure-based market in which capital and other resources are exchanged from a structural perspective stressing relationship alliances. I conclude by identifying the scope and limits of such an approach.

Does ethno-cultural betrayal in trauma affect Asian American/Pacific Islander college students' mental health outcomes? An exploratory study.

PubMed

Gómez, Jennifer M

2017-01-01

Interpersonal trauma has deleterious effects on mental health, with college students experiencing relatively high rates of lifetime trauma. Asian American/Pacific Islanders (AAPIs) have the lowest rate of mental healthcare utilization. According to cultural betrayal trauma theory, societal inequality may impact within-group violence in minority populations, thus having implications for mental health. In the current exploratory study, between-group (interracial) and within-group (ethno-cultural betrayal) trauma and mental health outcomes were examined in AAPI college students. Participants (N = 108) were AAPI college students from a predominantly white university. Data collection concluded in December 2015. Participants completed online self-report measures. A multivariate analysis of variance revealed that when controlling for interracial trauma, ethno-cultural betrayal trauma significantly impacted dissociation, hallucinations, posttraumatic stress symptoms, and hypervigilance. The results have implications for incorporating identity, discrimination, and ethno-cultural betrayal trauma victimization into assessments and case conceptualizations in therapy.

A characterization of pain in racially and ethnically diverse older adults: a review of the literature.

PubMed

Lavin, Robert; Park, Juyoung

2014-04-01

This article presents a critical review of the influence of interracial and ethnic variation on pain prevalence, intensity, interference/function/disability, and treatment in older adults. A search of scientific databases published from 1900 to 2011, using key words associated with pain, geriatrics, and race/ethnicity, identified 180 articles, of which 27 empirical studies met the inclusion criteria. Of the retained articles, 17 reported that race/ethnicity was a statistically significant factor at p < .05. Minority older adults reported a higher prevalence of pain and higher pain intensity, and variable responses regarding function/disability compared with responses by non-Hispanic White older adults. Minority older adults were less likely to receive prescription pharmacologic treatments and surgery, and they were more likely to use complementary and alternative medicine treatments. There are interracial/ethnic differences in pain assessment and treatment interventions among older adults.

Since 1993, following the National Thalassemia Major Prevention Program and an increase in immigration and interracial marriages, especially in southern Taiwan, the distribution of hemoglobinopathies may have changed. This study investigates the epidemiologic transition of hemoglobinopathies. We analyzed 1870 specimens collected between 2003 and 2012 in southern Taiwan, used gap-polymerase chain reaction and PCR-restriction fragment length polymorphism-based methods, and confirmed genotypes of hemoglobinopathies by DNA sequencing. We found a 91% reduction in the incidence of thalassemia major compared with samples from between 1986 and 1995. The most common genotypes of α-thalassemia and α Hb variants were the SEA type (69.4%) and Hb Quong Sze (1.54%). The most common genotypes of β-thalassemia and β Hb variants were IVS-II-654 (46.2%) and Hb E (2.2%), respectively. Compared with studies performed in different areas of and time intervals in Taiwan, a higher prevalence of -α 3.7 , Hb Quong Sze, and Hb E and a lower prevalence of the SEA type were found in this study. However, the SEA type remained the most common genotype observed. In addition, an increasing number of cases with an -α 3.7 type carrier, Hb Quong Sze carrier, and G γ (A γ δβ)° were identified following a peak of interracial marriages between 2003 and 2005, reflecting a regional difference and the impact of interracial marriage. In conclusion, global migration and international marriage have changed the distribution of hemoglobinopathies in Taiwan. A more comprehensive prenatal screening for new immigrants with a longer follow-up is warranted.

Health, trust, or "just understood": explicit and implicit condom decision-making processes among black, white, and interracial same-sex male couples.

Among gay and bisexual men, primary partners are a leading source of HIV infection. Trust, intimacy, and advancements in HIV treatment may impact same-sex male (SSM) couples' decisions to engage in unprotected anal intercourse (UAI). This qualitative study explored how Black, White and interracial couples discussed, and made decisions regarding condoms. Qualitative interviews were conducted with 48 SSM couples in the New York and San Francisco metropolitan areas. Stratified purposive sampling was used to include Black (n = 16), White (n = 17), and interracial (Black-White) (n = 15) couples. Twenty-six couples were concordant HIV-negative and 22 were HIV-discordant. Interviews were recorded, transcribed, coded, and analyzed using a grounded theory approach. Some couples described explicit processes, which involved active discussion, while others described implicit processes, where condom-use decisions occurred without any explicit discussion. These processes also differed by race and HIV status. Black couples tended to report condom-use as "just understood." White, HIV-discordant couples decided not to use condoms, with some identifying the HIV-positive partner's suppressed viral load and high CD4 count as deciding factors. After an unplanned episode of UAI, White, HIV-negative couples tended to discontinue condom use while Black HIV-negative couples decided to revert to using condoms. HIV prevention efforts focused on same-sex, male couples must consider the explicit/implicit nature of condom decision-making processes. Understanding differences in these processes and considering relationship dynamics, across race and HIV status, can promote the development of innovative couple-level, HIV prevention interventions.

Gonadal expression of aromatase and estrogen receptor alpha genes in two races of Tunisian mice and their hypofertile hybrids.

House mice (Mus musculus domesticus) in Tunisia consists of two races, one carries the 40-acrocentric standard karyotypes and the other one is a robertsonian race (2n=22) homozygous for nine centric fusions (Rb). The F1 hybrids between the two chromosomal races showed a significant decrease in reproductive success and litter size. Such results can be related to the formation of meiotic trivalent in the hybrids leading to the production of viable aneuploid gametes and post-zygotic elimination of embryos due to chromosomal non disjunction events at meiosis. Moreover, testicular histology of F1 and backcross males showed in some cases a breakdown in spermatogenesis. In both females and males, androgens but also estrogens play an important role in gametogenesis. In this study, we have studied aromatase and estrogen receptor alpha (ERalpha) gene expression in the gonads of the two parental races and their chromosomal hybrids. The results showed that aromatase and ERalpha mRNAs are expressed in hybrid males of inter-racial crosses (female22Rb x male40Std and female40Std x male22Rb) and in hybrid females of inter-racial crosses (female22Rb x male40Std) as in the two parental races. However, in hybrid females of inter-racial crosses (female40Std x male22Rb) the amount of aromatase transcripts decreased sharply suggesting that this gene is involved in the breakdown of hybrid fertility in females, but not in males. However, in hybrid males, a putative post-translational modification of this enzyme, in terms of activity, should be verified.

Stress and coping in interracial contexts: The influence of race-based rejection sensitivity and cross-group friendship in daily experiences of health

PubMed Central

Page-Gould, Elizabeth; Mendoza-Denton, Rodolfo; Mendes, Wendy Berry

2014-01-01

We examined the interplay of psychosocial risk and protective factors in daily experiences of health. In Study 1, the tendency to anxiously expect rejection from racial outgroup members, termed race-based rejection sensitivity (RS-race), was cross-sectionally related to greater stress-symptoms among Black adults who reported fewer cross-race friends but not among participants who had more cross-race friends. In Study 2, we experimentally manipulated the development of a same- versus cross-race friendship among Latino/a-White dyads prior to collecting daily experiences of stress-symptoms using a diary methodology. While RS-race predicted more psychosomatic symptoms in the same-race friendship condition, RS-race was unrelated to symptomatology among participants who made a cross-race friend. These findings suggest that experiences of intergroup stress can spill over into everyday life in the absence of positive contact, but cross-race friendships may be a resource that mitigates the expression of interracial stress.

Contagious Anxiety: Anxious European Americans Can Transmit Their Physiological Reactivity to African Americans.

PubMed

West, Tessa V; Koslov, Katrina; Page-Gould, Elizabeth; Major, Brenda; Mendes, Wendy Berry

2017-12-01

During interracial encounters, well-intentioned European Americans sometimes engage in subtle displays of anxiety, which can be interpreted as signs of racial bias by African American partners. In the present research, same-race and cross-race stranger dyads ( N = 123) engaged in getting-acquainted tasks, during which measures of sympathetic nervous system responses (preejection period, PEP) and heart rate variability were continuously collected. PEP scores showed that African American partners had stronger physiological linkage to European American partners who evidenced greater anxiety-greater cortisol reactivity, behavioral tension, and self-reported discomfort-which suggests greater physiological responsiveness to momentary changes in partners' affective states when those partners were anxious. European Americans showed physiological linkage to African American and European American partners, but linkage did not vary as a function of their partner's anxiety. Using physiological linkage offers a novel approach to understanding how affective responses unfold during dynamic intergroup interactions.

Maeder, Evelyn M; Mossière, Annik; Cheung, Liann

2013-03-01

This study manipulated the race of the defendant and the victim (White/White, White/Asian, Asian/Asian, and Asian/White) in a domestic violence case to examine the potential prejudicial impact of race on juror decision making. A total of 181 undergraduate students read a trial transcript involving an allegation of spousal abuse in which defendant and victim race were manipulated using photographs. They then provided a verdict and confidence rating, a sentence, and responsibility attributions, and completed various scales measuring attitudes toward wife abuse and women. Findings revealed that female jurors were harsher toward the defendant than were male jurors. When controlling for attitudes toward Asians, jurors found the defendant guilty more often in cases involving interracial couples, as compared to same-race couples. Path analyses revealed various factors and attitudes involved in domestic violence trial outcomes. Findings contribute to the scarce literature on legal proceedings involving Asians, particularly in domestic violence cases. Outcomes also provide a model for relevant factors and characteristics of jurors in domestic violence cases. Roadblocks inherent in jury research are also discussed.

Breaking the Silence: Time to Talk About Race and Racism.

PubMed

Acosta, David; Ackerman-Barger, Kupiri

2017-03-01

Recent events in the United States have catalyzed the need for all educators to begin paying attention to and discovering ways to dialogue about race. No longer can health professions (HP) educators ignore or avoid these difficult conversations. HP students are now demanding them. Cultural sensitivity and unconscious bias training are not enough. Good will and good intentions are not enough. Current faculty development paradigms are no longer sufficient to meet the educational challenges of delving into issues of race, power, privilege, identity, and social justice.Engaging in such conversations, however, can be overwhelmingly stressful for untrained faculty. The authors argue that before any curriculum on race and racism can be developed for HP students, and before faculty members can begin facilitating conversations about race and racism, faculty must receive proper training through intense and introspective faculty development. Training should cover how best to engage in, sustain, and deepen interracial dialogue on difficult topics such as race and racism within academic health centers (AHCs). If such faculty development training-in how to conduct interracial dialogues on race, racism, oppression, and the invisibility of privilege-is made standard at all AHCs, HP educators might be poised to actualize the real benefits of open dialogue and change.

Identification of facial shape by applying golden ratio to the facial measurements: an interracial study in malaysian population.

Packiriswamy, Vasanthakumar; Kumar, Pramod; Rao, Mohandas

2012-12-01

The "golden ratio" is considered as a universal facial aesthetical standard. Researcher's opinion that deviation from golden ratio can result in development of facial abnormalities. This study was designed to study the facial morphology and to identify individuals with normal, short, and long face. We studied 300 Malaysian nationality subjects aged 18-28 years of Chinese, Indian, and Malay extraction. The parameters measured were physiognomical facial height and width of face, and physiognomical facial index was calculated. Face shape was classified based on golden ratio. Independent t test was done to test the difference between sexes and among the races. The mean values of the measurements and index showed significant sexual and interracial differences. Out of 300 subjects, the face shape was normal in 60 subjects, short in 224 subjects, and long in 16 subjects. As anticipated, the measurements showed variations according to gender and race. Only 60 subjects had a regular face shape, and remaining 240 subjects had irregular face shape (short and long). Since the short and long shape individuals may be at risk of developing various disorders, the knowledge of facial shapes in the given population is important for early diagnostic and treatment procedures.

Gender and racial favouritism in black and white preschool girls.

PubMed

Kurtz-Costes, Beth; Defreitas, Stacie C; Halle, Tamara G; Kinlaw, C Ryan

2011-06-01

The authors examined gender and racial preferential behaviour in 108 3- and 5-year-old Black and White girls. Children set up a birthday party for dolls that differed in gender and racial physical characteristics. Whereas White girls showed favouritism towards the doll most closely resembling themselves in both gender and race, Black girls showed most favouritism towards the White girl doll. Black girls were more likely to show preference based on gender rather than race, whereas White girls were equally likely to show race- or gender-based favouritism. Among White 5-year-olds, greater prior interaction with Blacks was positively associated with race-related favouritism (i.e., secondary preference to the White boy doll rather than the Black girl doll). Interracial contact was unrelated to racial favouritism among the other three groups. Results demonstrate the salience of gender identity during the preschool years, and indicate that majority/minority status and intergroup contact shape the development of collective identity and social behaviour.

2002-01-01

This article compares interracial or gender differences of six intraoral dental parameters among six racial groups (African American, Caucasian, Chinese, Hispanic, Japanese, and Korean). The same 253 patients participating in part 1 were included in this portion of the study to evaluate six intraoral parameters. The data were collected and analyzed using a one-way analysis of variance, followed by the Tukey-Kramer test for honestly significant difference when statistically significant differences were found (P < .05). Women displayed significantly more gingival tissue in four of the six races, and African Americans displayed significantly more gingival tissue than any other race. Women had significantly more missing teeth than men in three of the six races studied. Japanese subjects had significantly fewer missing teeth and smaller maxillary central incisors than all other groups except Caucasians. Women had significantly narrower maxillary central incisors in three of the races. There was a significantly higher prevalence of Angle Class III relationships in Chinese subjects. The Japanese had significantly more Class II molar relationships than other races. Racial and gender differences were found in gingival tissue display, the number of missing teeth, maxillary right central incisor crown width, and Angle molar classification, but not in the amount of vertical or horizontal overlap of the anterior teeth.

The N400 as an index of racial stereotype accessibility.

PubMed

Hehman, Eric; Volpert, Hannah I; Simons, Robert F

2014-04-01

The current research examined the viability of the N400, an event-related potential (ERP) related to the detection of semantic incongruity, as an index of both stereotype accessibility and interracial prejudice. Participants' EEG was recorded while they completed a sequential priming task, in which negative or positive, stereotypically black (African American) or white (Caucasian American) traits followed the presentation of either a black or white face acting as a prime. ERP examination focused on the N400, but additionally examined N100 and P200 reactivity. Replicating and extending previous N400 stereotype research, results indicated that the N400 can indeed function as an index of stereotype accessibility in an interracial domain, as greater N400 reactivity was elicited by trials in which the face prime was incongruent with the target trait than when primes and traits matched. Furthermore, N400 activity was moderated by participants' self-reported explicit bias. More explicitly biased participants demonstrated greater N400 reactivity to stereotypically white traits following black faces than black traits following black faces. P200 activity was additionally associated with participants' implicit biases, as more implicitly biased participants similarly demonstrated greater P200 reactivity to stereotypically white traits following black faces than black traits following black faces.

Convergent RANK- and c-Met-mediated signaling components predict survival of patients with prostate cancer: an interracial comparative study.

We reported (PLoS One 6 (12):e28670, 2011) that the activation of c-Met signaling in RANKL-overexpressing bone metastatic LNCaP cell and xenograft models increased expression of RANK, RANKL, c-Met, and phosphorylated c-Met, and mediated downstream signaling. We confirmed the significance of the RANK-mediated signaling network in castration resistant clinical human prostate cancer (PC) tissues. In this report, we used a multispectral quantum dot labeling technique to label six RANK and c-Met convergent signaling pathway mediators simultaneously in formalin fixed paraffin embedded (FFPE) tissue specimens, quantify the intensity of each expression at the sub-cellular level, and investigated their potential utility as predictors of patient survival in Caucasian-American, African-American and Chinese men. We found that RANKL and neuropilin-1 (NRP-1) expression predicts survival of Caucasian-Americans with PC. A Gleason score ≥ 8 combined with nuclear p-c-Met expression predicts survival in African-American PC patients. Neuropilin-1, p-NF-κB p65 and VEGF are predictors for the overall survival of Chinese men with PC. These results collectively support interracial differences in cell signaling networks that can predict the survival of PC patients.

Suspicion of Motives Predicts Minorities' Responses to Positive Feedback in Interracial Interactions.

PubMed

Major, Brenda; Kunstman, Jonathan W; Malta, Brenna D; Sawyer, Pamela J; Townsend, Sarah S M; Mendes, Wendy Berry

2016-01-01

Strong social and legal norms in the United States discourage the overt expression of bias against ethnic and racial minorities, increasing the attributional ambiguity of Whites' positive behavior to ethnic minorities. Minorities who suspect that Whites' positive overtures toward minorities are motivated more by their fear of appearing racist than by egalitarian attitudes may regard positive feedback they receive from Whites as disingenuous. This may lead them to react to such feedback with feelings of uncertainty and threat. Three studies examined how suspicion of motives relates to ethnic minorities' responses to receiving positive feedback from a White peer or same-ethnicity peer (Experiment 1), to receiving feedback from a White peer that was positive or negative (Experiment 2), and to receiving positive feedback from a White peer who did or did not know their ethnicity (Experiment 3). As predicted, the more suspicious Latinas were of Whites' motives for behaving positively toward minorities in general, the more they regarded positive feedback from a White peer who knew their ethnicity as disingenuous and the more they reacted with cardiovascular reactivity characteristic of threat/avoidance, increased feelings of stress, heightened uncertainty, and decreased self-esteem. We discuss the implications for intergroup interactions of perceptions of Whites' motives for nonprejudiced behavior.

Broken boundaries or broken marriages? Racial intermarriage and divorce in the United States.

PubMed

Fu, Vincent Kang; Wolfinger, Nicholas H

2011-01-01

Several recent studies have investigated the consequences of racial intermarriage for marital stability. None of these studies properly control for first-order racial differences in divorce risk, therefore failing to appropriately identify the effect of intermarriage. Our article builds on an earlier generation of studies to develop a model that appropriately identifies the consequences of crossing racial boundaries in matrimony. We analyze the 1995 and 2002 National Survey of Family Growth using a parametric event-history model called a sickle model. To appropriately identify the effect of interracial marriage we use the interaction of wife's race and husband's race. We find elevated divorce rates for Latino/white intermarriages but not for black/white intermarriages. Seventy-two percent of endogamous Latino marriages remain intact at 15 years, but only 58 percent of Latino husband/white wife and 64 percent of white husband/Latina wife marriages are still intact. We have identified an important deficiency in previous studies and provide a straightforward resolution. Although higher rates of Latino/white intermarriage may indicate more porous group boundaries, the greater instability of these marriages suggests that these boundaries remain resilient.

White Anglo-Saxon hopes and black Americans' Atlantic dreams: Jack Johnson and the British boxing colour bar.

PubMed

Runstedtler, Theresa

2010-01-01

This article examines the controversy surrounding Jack Johnson's proposed world heavyweight title fight against the British champion Bombardier Billy Wells in London (1911). In juxtaposing African Americans' often glowing discussions of European tolerance with the actual white resistance the black champion faced in Britain, including the Home Office's eventual prohibition of the match, the article explores the period's transnational discourses of race and citizenship. Indeed, as white sportsmen on both sides of the Atlantic joined together in their search for a "White Hope" to unseat Johnson, the boxing ring became an important cultural arena for interracial debates over the political and social divisions between white citizens and nonwhite subjects. Although African Americans had high hopes for their hero's European sojourn, the British backlash against the Johnson-Wells match underscored the fact that their local experiences of racial oppression were just one facet of a much broader global problem. At the same time, the proposed prizefight also made the specter of interracial conflict in the colonies all the more tangible in the British capital, provoking public discussions about the merits of U.S. racial segregation, along with the need for white Anglo-Saxon solidarity around the world. Thus, this article not only exposes the underlying connections between American Jim Crow and the racialized fault lines of British imperialism, but it also traces the "tense and tender ties" linking U.S. and African American history with the new imperial history and postcolonial studies.

Crowds include allegiances that may be distinguished by visual cues to shared behavior and mental states, providing perceivers with direct information about social groups and thus a basis for learning social categories. Here, emotion expressions signaled group membership: to the extent that a crowd exhibited emotional segregation (i.e., was segregated into emotional subgroups), a visible characteristic (race) that incidentally distinguished emotional subgroups was expected to support categorical distinctions. Participants were randomly assigned to view interracial crowds in which emotion differences between (black vs. white) subgroups were either small (control condition) or large (emotional segregation condition). On each trial, participants saw crowds of 12 faces (6 black, 6 white) for roughly 300 ms and were asked to estimate the average emotion of the entire crowd. After all trials, participants completed a racial categorization task and self-report measure of race essentialism. As predicted, participants exposed to emotional segregation (vs. control) exhibited stronger racial category boundaries and stronger race essentialism. Furthermore, such effects accrued via ensemble coding, a visual mechanism that summarizes perceptual information: emotional segregation strengthened participants' racial category boundaries to the extent that segregation limited participants' abilities to integrate emotion across racial subgroups. Together with evidence that people observe emotional segregation in natural environments, these findings suggest that crowd perception mechanisms support racial category boundaries and race essentialism.

Previous research suggests that people show increased self-referential processing when they provide criticism to others, and that this self-referential processing can have negative effects on interpersonal perceptions and behavior. The current research hypothesized that adopting a self-distanced perspective (i.e. thinking about a situation from a non-first person point of view), as compared with a typical self-immersed perspective (i.e. thinking about a situation from a first-person point of view), would reduce self-referential processing during the provision of criticism, and in turn improve interpersonal perceptions and behavior. We tested this hypothesis in an interracial context since research suggests that self-referential processing plays a role in damaging interracial relations. White participants prepared for mentorship from a self-immersed or self-distanced perspective. They then conveyed negative and positive evaluations to a Black mentee while electroencephalogram (EEG) was recorded. Source analysis revealed that priming a self-distanced (vs self-immersed) perspective predicted decreased activity in regions linked to self-referential processing (medial prefrontal cortex; MPFC) when providing negative evaluations. This decreased MPFC activity during negative evaluations, in turn, predicted verbal feedback that was perceived to be more positive, warm and helpful. Results suggest that self-distancing can improve interpersonal perceptions and behavior by decreasing self-referential processing during the provision of criticism. © The Author (2016).

Workplace discrimination has grown more ambiguous, with interracial interactions often perceived differently by different people. The present study adds to the literature by examining a key individual difference variable in the perception of discrimination at work, namely individual color-blind attitudes. We examined relationships between 3 dimensions of color-blind attitudes (Racial Privilege, Institutional Discrimination, and Blatant Racial Issues) and perceptions of racial microaggressions in the workplace as enacted by a White supervisor toward a Black employee (i.e., discriminatory actions ranging from subtle to overt). Findings showed that observer views on institutional discrimination fully mediated, and blatant racial issues partially mediated, the relationships between racial group membership and the perception of workplace microaggressions. Non-Hispanic Whites endorsed color blindness as institutional discrimination and blatant racial issues significantly more than members of racioethnic minority groups, and higher levels of color-blind worldviews were associated with lower likelihoods of perceiving microaggressions. Views on racial privilege did not differ significantly between members of different racial groups or affect microaggression perceptions. Implications for organizations concerned about promoting more inclusive workplaces are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Culture Connection Project: promoting multiculturalism in elementary schools.

To promote multiculturalism among grade school students through drama education. Grade 3-6 students (N = 665) from 6 targeted schools including lead-class students (n = 158) representing each school. Elementary schools in Windsor-Essex County, Ontario, Canada. In this non-experimental design study, group discussions conducted with each lead class to explore students' understanding of multiculturalism were developed into an interactive drama performance and performed for all grades 3-6 students in their respective schools. A follow-up drama workshop was offered to each lead class one week after the drama performance. All students completed a 7-item questionnaire before and after the drama performance and after the drama workshop. Pre-test and post-test data collected were analyzed using T-test and ANOVA to determine the effects of drama education on students' attitudes toward multiculturalism. Statistical analysis at 0.05 significance level revealed that both the performance and the drama workshop heightened students' awareness of racism, and instilled cultural respect through "talking with others", "accepting others", and "believing that they can make a difference" in multiculturalism promotion. Drama education was an effective experiential tool for promoting multiculturalism in a school setting. The key to promoting inter-racial harmony is to respect and accept individual differences and to broaden the social determinants of health by providing culture safety care.

The present study is the first to apply Trawalter, Richeson, and Shelton's (2009) stress and coping framework to qualitatively examine interracial interactions in initial sessions of psychotherapy. The sample included 22 dyads: 15 therapists of color administering various treatment modalities to 15 treatment-seeking non-Latino White (NLW) patients and a comparison group of 7 intraracial (NLW-NLW) dyads. In Phase 1, videorecordings of the first session of treatment were analyzed using inductive thematic analysis (TA) to describe patient and therapist behaviors. In Phase 2, a deductive TA approach was used to interpret and cluster those dyadic behaviors according to Trawalter et al.'s (2009) framework. NLW patients paired with therapists of color made more efforts to bridge differences and more often questioned the therapist's professional qualifications compared with those matched with NLW therapists. Therapists of color made more self-disclosures than NLW therapists and maintained a more formal stance, compared with NLW therapists. The deductive TA operationalized 4 of Trawalter and colleagues' (2009) coping responses within a therapeutic framework. Findings highlight the ability of therapists' of color to engage positively with their NLW patients even in the face of challenges to their expertise and credibility.

D'Eichthal and Urbain's "Lettres sur la race noire et la race blanche": race, gender, and reconciliation after slave emancipation.

PubMed

Andrews, Naomi J

2011-01-01

This article is a close reading of Gustave D'Eichthal and Ishmayl Urbain's Lettres sur la race noire et la race blanche (1839), written during the decade prior to the "second" French emancipation in 1848. The article argues that the hierarchical gendering of race described in the letters is reflective of metropolitan concerns about potential for social disorder accompanying slave emancipation in the French colonies. In arguing for social reconciliation through interracial marriage and its offspring, the symbolically charged figure of the mulatto, the authors deployed gendered and familial language to describe a stable post-emancipation society.

Over the past decades, several studies have shown that tumor-related somatic and germline alterations predicts tumor prognosis, drug response and toxicity. Latin American populations present a vast geno-phenotypic diversity due to the great interethnic and interracial mixing. This genetic flow leads to the appearance of complex characteristics that allow individuals to adapt to endemic environments, such as high altitude or extreme tropical weather. These genetic changes, most of them subtle and unexplored, could establish a mutational profile to develop new pharmacogenomic therapies specific for Latin American populations. In this review, we present the current status of research on somatic and germline alterations in Latin America compared to those found in Caucasian and Asian populations.

Race Making in a Penal Institution.

PubMed

Walker, Michael L

2016-01-01

This article provides a ground-level investigation into the lives of penal inmates, linking the literature on race making and penal management to provide an understanding of racial formation processes in a modern penal institution. Drawing on 135 days of ethnographic data collected as an inmate in a Southern California county jail system, the author argues that inmates are subjected to two mutually constitutive racial projects--one institutional and the other microinteractional. Operating in symbiosis within a narrative of risk management, these racial projects increase (rather than decrease) incidents of intraracial violence and the potential for interracial violence. These findings have implications for understanding the process of racialization and evaluating the effectiveness of penal management strategies.

Structural, magnetic and optical properties of Y bFe{sub 2}O{sub 4} films deposited by spin coating

Rare-earth iron oxides (RFe{sub 2}O{sub 4}) have attracting attention as new electronic device materials because of their numerous functionalities, such as electronic ferroelectricity, ferrimagnetism, and high infrared absorption. In this paper, nearly monophasic Y bFe{sub 2}O{sub 4} films were prepared on α-Al{sub 2}O{sub 3}(001) substrates by the spin coating method using an aqueous-based Y bFe{sub 2}O{sub 4} solution. The solution was composed of a stoichiometric ratio of Y b(CH{sub 3}COO){sub 3} and Fe(NO{sub 3}){sub 3} with excess chelating agents. After heat treatment above 800 °C, well-crystallized and highly (001)-oriented Y bFe{sub 2}O{sub 4} started to epitaxially form on the substrate undermore » controlled oxygen partial pressure with H{sub 2}/CO{sub 2} gas mixtures. X-ray pole figure analysis confirmed the following epitaxial relationship: Y bFe{sub 2}O{sub 4}[100](001)//α-Al{sub 2}O{sub 3}[100](001). Moreover formation of an Fe{sub 3}O{sub 4} interracial layer between Y bFe{sub 2}O{sub 4} and α-Al{sub 2}O{sub 3} was detected by high-resolution transmission electron microscopy. Presence of the Fe{sub 3}O{sub 4} interracial layer seemed to release the lattice misfit with the substrate. The Fe{sup 2+}/Fe{sup 3+} ratio in the obtained Y bFe{sub 2}O{sub 4} films was nearly stoichiometric and the indirect bandgap assigned to Fe{sup 2+} → Fe{sup 3+} charge transfer excitation was found to be ∼0.4 eV by optical spectroscopy. A clear magnetic transition from the paramagnetic state to the ferrimagnetic state occurred at ∼230 K.« less

Graziano, Kevin J

2004-08-01

Guided by photovoice, a form of participatory action research that uses documentary photography and storytelling, this study examines how Black gay men and lesbians view themselves in relation to White gay men and lesbians in South Africa. Participants were from 4 South African townships and included 4 women, and 3 men. Participants discussed interracial dating, a lack of education, and information regarding differing sexualities and health care. They reported being sexually and physically assaulted for challenging the heterosexual status quo. Other themes that emerged from this study were classism, cultural traditions of visiting African healers, and segregated social spaces. Amidst oppression and despair, participants showed signs of strength, hope, and optimism.

Is there an own-race preference in attractiveness?

2013-08-15

Even in multicultural nations interracial relationships and marriages are quite rare, one reflection of assortative mating. A relatively unexplored factor that could explain part of this effect is that people may find members of their own racial group more attractive than members of other groups. We tested whether there is an own-race preference in attractiveness judgments, and also examined the effect of familiarity by comparing the attractiveness ratings given by participants of different ancestral and geographic origins to faces of European, East Asian and African origin. We did not find a strong own-race bias in attractiveness judgments, but neither were the data consistent with familiarity, suggesting an important role for other factors determining the patterns of assortative mating observed.

Human leukocyte antigen class I (A, B and C) allele and haplotype variation in a South African Mixed ancestry population.

South Africa has a large (∼53million), ethnically diverse population (black African, Caucasian, Indian/Asian and Mixed ancestry) and a high disease burden (particularly HIV-1 and Mycobacterium tuberculosis). The Mixed ancestry population constitutes ∼9% of the total population and was established ∼365years ago in the Western Cape region through interracial mixing of black Africans, Europeans and Asians. Admixed populations present unique opportunities to identify genetic factors involved in disease susceptibility. Since HLA genes are important mediators of host immunity, we investigated HLA-A, -B and -C allele and haplotype diversity in 50 healthy, unrelated individuals recruited from the Mixed ancestry population.

Neurocognitive Basis of Racial Ingroup Bias in Empathy.

PubMed

Han, Shihui

2018-05-01

Racial discrimination in social behavior, although disapproved of by many contemporary cultures, has been widely reported. Because empathy plays a key functional role in social behavior, brain imaging researchers have extensively investigated the neurocognitive underpinnings of racial ingroup bias in empathy. This research has revealed consistent evidence for increased neural responses to the perceived pain of same-race compared with other-race individuals in multiple brain regions and across multiple time-windows. Researchers have also examined neurocognitive, sociocultural, and environmental influences on racial ingroup bias in empathic neural responses, as well as explored possible interventions to reduce racial ingroup bias in empathic brain activity. These findings have important implications for understanding racial ingroup favoritism in social behavior and for improving interracial communication. Copyright © 2018 Elsevier Ltd.

X-ray and neutron reflectivity are two non destructive techniques which provide a wealth of information on thickness, structure and interracial properties in nanometer length scale. Combination of X-ray and neutron reflectivity is well suited for obtaining physical parameters of nanostructured thin films and superlattices. Neutrons provide a different contrast between the elements than X-rays and are also sensitive to the magnetization depth profile in thin films and superlattices. The real space information is extracted by fitting a model for the structure of the thin film sample in reflectometry experiments.

In 1938, President Franklin D. Roosevelt and his law partner Basil O'Connor formed the National Foundation for Infantile Paralysis (NFIP) to battle the viral disease poliomyelitis. Although the NFIP program was purported to be available for all Americans irrespective of "race, creed, or color," officials encountered numerous difficulties upholding this pledge in a nation divided by race. In 1944, NFIP officials hired educator Charles H. Bynum to head a new department of "Negro Activities." Between 1944 and 1954, Bynum negotiated the NFIP bureaucracy to educate officials and influence their national health policy. As part of the NFIP team, he helped increase interracial fund-raising in the March of Dimes, improve polio treatment for black Americans, and further the civil rights movement.

Racial stereotypes and interracial attraction: phenotypic prototypicality and perceived attractiveness of Asians.

PubMed

Wilkins, Clara L; Chan, Joy F; Kaiser, Cheryl R

2011-10-01

What does it take to find a member of a different race attractive? In this research, we suggest that for Whites, attraction to Asians may be based, in part, on stereotypes and variations in Asians' racial appearance. Study 1 reveals that Asians are stereotyped as being more feminine and less masculine than other racial groups-characteristics considered appealing for women but not for men to possess. Study 2 examines how variation in racial appearance, phenotypic prototypicality (PP), shapes the degree to which Asians are gender stereotyped and how PP relates to perceptions of attractiveness. Higher PP Asian men are perceived as being less masculine and less physically attractive than lower PP Asian men. These findings inform theory on how within-group variation in racial appearance affects stereotyping and other social outcomes.

They don't all look alike: individuated impressions of other racial groups.

Reliability, content, and homogeneity of own- and other-race impressions were assessed: U.S. White, U.S. Black, and Korean students rated faces of White, Black, or Korean men. High intraracial reliabilities revealed that people of 1 race showed equally high agreement regarding the traits of own- and other-race faces. Racially universal appearance stereotypes--the attractiveness halo effect and the babyface overgeneralization effect--contributed substantially to interracial agreement, which was only marginally lower than intraracial agreement. Moreover, similar attention to variations in appearance yielded similar degrees of own- and other-race trait differentiation. When own- and other-race differences in the differentiation of faces on babyfaceness were statistically controlled, differences in trait differentiation were eliminated. Despite the individuated impressions of other-race faces, certain racial stereotypes persisted.

Elderly homicide in Chicago: a research note.

2007-01-01

There is a body of knowledge about elderly crime victims, but we know little about the characteristics of elderly perpetrators, especially of homicide. The few studies that have been published are based on small samples and are somewhat dated. In an examination of homicides committed in Chicago over a 31-year period, we compared cases involving perpetrators aged over 60 years (n = 443) with those involving younger perpetrators (n = 24,066). There were a number of significant differences. Elderly killers were more likely to be White and to commit suicide afterwards. Their victims were more likely to be spouses, females, and aged over 60 years. Inter-racial homicide was more common for younger offenders. The low number of homicides involving the elderly is explained by reference to routine activity theory. Copyright 2007 John Wiley & Sons, Ltd.

This research investigated the relation between racial categorization and implicit racial bias in majority and minority children. Chinese and Indian 3- to 7-year-olds from Singapore (N = 158) categorized Chinese and Indian faces by race and had their implicit and explicit racial biases measured. Majority Chinese children, but not minority Indian children, showed implicit bias favoring own race. Regardless of ethnicity, children's racial categorization performance correlated positively with implicit racial bias. Also, Chinese children, but not Indian children, displayed explicit bias favoring own race. Furthermore, children's explicit bias was unrelated to racial categorization performance and implicit bias. The findings support a perceptual-social linkage in the emergence of implicit racial bias and have implications for designing programs to promote interracial harmony. © 2017 The Authors.

Color-blind racial ideology: theory, training, and measurement implications in psychology.

PubMed

Neville, Helen A; Awad, Germine H; Brooks, James E; Flores, Michelle P; Bluemel, Jamie

2013-09-01

Synthesizing the interdisciplinary literature, we characterize color-blind racial ideology (CBRI) as consisting of two interrelated domains: color-evasion (i.e., denial of racial differences by emphasizing sameness) and power-evasion (i.e., denial of racism by emphasizing equal opportunities). Mounting empirical data suggest that the color-evasion dimension is ineffective and in fact promotes interracial tension and potential inequality. CBRI may be conceived as an ultramodern or contemporary form of racism and a legitimizing ideology used to justify the racial status quo. Four types of CBRI are described: denial of (a) race, (b) blatant racial issues, (c) institutional racism, and (d) White privilege. We discuss empirical findings suggesting a relationship between CBRI and increased racial prejudice, racial anger, and racial fear. Implications for education, training, and research are provided. © 2013 APA, all rights reserved.

Mixing against culture vs mixing against nature: ontologization of prohibited interethnic relationships.

PubMed

Roncarati, Alessandra; Pérez, Juan A; Ravenna, Marcella; Navarro-Pertusa, Esperanza

2009-02-01

In this paper, we develop the theory of ontologization: Social representations that prevent members of minority and majority groups who are living in contact with each other to mingle. The process of ontologization consists of separating some humans from their own species, and anchoring them in another environment, that of an animal, for example. We propose that underlying the famous slogan "equal but separate" is the social representation of interracial mixing as a "counter-nature" phenomenon. It is predicted that a sexual relationship between people of different "races" leads to a greater degree of ontologization, and, as such, this miscegenation will be explained in terms of biologistic thinking, like an instinctive nature or atavistic animal impulse. An experiment (N = 360) features the case of a woman who, though already in a stable relationship, is unfaithful to her partner. In a 2×3 factor design, the ethnic-national identity of this woman (in-group: Spanish/Italian vs out-group: Senegalese) and the ethnic-national identity of her lovers (in-group: Spanish/Italian vs out-group: Rumanian vs out-group: Senegalese) were manipulated. In general, results fit the hypothesis of ontologization in interracial conditions better, rather than the customary in-group favouritism and/or out-group discrimination bias. We then go on to discuss the way in which a biologistic way of thinking enables a differentiation at the human level, in terms of culture groups and nature groups, in "races," so that an interracial sexual relationship is seen as evidence of a wild and irrepressible impulse, which stigmatizes the people involved in these relationships. This research was supported by the Italian/Spanish Integrated Action Program HI2004_0241 and the Spanish Ministerio de Ciencia y Tecnología BSO2003-00476/PSCE. Dans cet article, nous développons la théorie de l'ontologisation: des représentations sociales qui empêchent les membres des groupes minoritaire et majoritaire qui vivent en contact les uns avec les autres d'intergir ensemble. Le processus d'ontologisation consiste à séparer quelques humains de leur propre espèce et de les ancrer dans un autre environnement, celui des animaux, à titre d'exemple. Nous proposons que ce qui est sous-jacent au fameux slogan «égaux mais distincts» est la représentation sociale de mélange inter-racial comme un phénomène «contre-nature». Il est prédit qu'une relation sexuelle entre des gens de différentes «races» amènerait à un plus grand degré d'ontologisation et en tant que tel, ce mélange sera expliqué en termes de pensée biologistique, à l'instar d'une nature instinctuelle ou une impulsion animale atavistique. Une expérimentation (N = 360) présente le cas d'une femme qui, même si elle est déjà dans une relation stable, elle est infidèle à son partenaire. Dans un devis 2×3, l'identité ethno-nationale de cette femme (endogroupe-espagnol/italien vs. exogroupe-sénégalais) et l'identité ethno-nationale de ses amants (endogroupe-espagnol/italien vs. exogroupe-roumain vs. exogroupe-sénégalais) ont été manipulées. En général, les résultats soutiennent l'hypothèse de l'ontologisation mieux dans les condition inter-raciales plutôt que le favoritisme de l'endogroupe coutumier et/ou le biais de la discrimination de l'exogroupe. Ensuite, nous poursuivons en discutant la manière dont la façon de penser biologistique permet une différentiation au niveau humain, en termes de groupes culturels et de groupes naturels, dans des «races», de manière à ce qu'une relation sexuelle inter-raciale est vue comme une preuve d'une impulsion sauvage et irrépressible qui peut stigmatiser les gens impliqués dans ces relations. En el presente artículo se discute la teoría de la ontologización: representaciones sociales que prevenien la fusión entre los miembros de grupos minoritarios o mayoritarios que viven en contacto unos con otros. El proceso de ontologización consiste en la separación de algunos seres humanos de sus propias especies y en la reubicación de estos en otro medio ambiente, por ejemplo el de un animal. Nosotros suponemos basados en el famoso eslogan "igual pero diferente" que la representación social de una mixtura interracial es un fenómeno "antinatural". Se ha observado que relaciones sexuales entre personas de "razas" diferentes conllevan a un elevado nivel de ontologización. Desde una perspectiva biologista se explica esta mezcla racial en términos de un instinto natural o de impulsos animales ancestrales. En un experimento (N =  360) se presenta el caso de una mujer, que a pesar de estar en una relación estable, no es fiel a su pareja. En un dieseño con 2×3 factores se manipuló la identidad étnica-nacional de esta mujer (intragrupo español/italiano vs. exogrupo senegalés) y la identidad étnica-nacional de sus amantes (intragrupo español/italiano vs. exogrupo rumano vs. exogrupo senegalés). En general los resultados apoyan más claramente la hipótesis de la ontologización en condiciones interraciales, que la acostumbrada hipótesis relacionada con sesgos de favoritismo hacia el intragrupo y/o de discriminación hacia el exogrupo. Posteriormente se discutió en que medida un aproximación de tipo biologista posibilita una diferenciación a nivel humano, en términos de grupos culturales y grupos naturales, en "razas", de tal medida que relaciones sexuales interraciales son vistas como evidencia de un impulso salvaje e incontrolable, el cual estigmatiza a las personas envueltas en estas relaciones.

Wetting Behavior of Mold Flux Droplet on Steel Substrate With or Without Interfacial Reaction

NASA Astrophysics Data System (ADS)

Zhou, Lejun; Li, Jingwen; Wang, Wanlin; Sohn, Il

2017-08-01

The slag entrapment in mold tends to cause severe defects on the slab surface, especially for casting steels containing active alloy elements such as Al, Ti, and Mn. The wetting behavior of molten mold flux on the initial solidified shell is considered to be a key factor to determine the entrapment of mold slag on the shell surface. Therefore, the wetting behavior of mold flux droplet on the steel substrate with or without interfacial reaction was investigated by the sessile drop method. The results indicated that the melting process of mold flux has a significant influence on the variation of contact angle, and the final contact angle for Flux1 droplet on 20Mn23AlV is only 15 deg, which is lower than the other two cases due to the intensive interracial reactions occurring in this case. In addition, the thickness of the interaction layer for the case of Flux1 on 20Mn23AlV is 10- μm greater than the other two cases, which confirms that the most intensive reactions occurred at the interface area. The microstructure and element distribution at the interface analyzed by a scanning electron microscope (SEM) and energy dispersive spectrum (EDS) suggested that the increase of wettability of mold flux droplet on the steel substrate is caused by the migration of Al, Mn, and Si elements occurring in the vicinity of the interface. The results obtained in this article can reveal the mechanism of flux entrapment by hook or shell and provide theoretic guidance for mold flux design and optimization.

Precious African American memories, post-racial dreams & the American nation.

PubMed

Martin, Waldo E

2011-01-01

This interdisciplinary essay explores a fundamental paradox at the heart of American race relations since the 1960s: "the changing same." The more things change; the more they remain the same. Combining historical and social-scientific evidence with autobiographical reflections, this discussion critically probes the paradoxical decline and persistence of two dimensions of our enduring racial quagmire: racial inequality and white supremacy. The essay argues that these powerful and interrelated elements of America's continuing racial dilemma demand a massive democratic movement to alleviate both at once. This wide-ranging struggle to realize the promise of American democracy requires more than just a revitalized African American Freedom Struggle that is both intraracial and interracial. Progress toward resolving the seemingly intractable problem of racial inequality in the United States demands far more than intensified efforts to alleviate economic inequality; it requires alleviating white supremacy as well.

Discrimination and psychiatric disorder among Asian American immigrants: a national analysis by subgroups.

PubMed

Li, Miao

2014-12-01

Although considerable evidence suggests that discrimination negatively affects mental health for Asian American (AA) immigrants, few studies have disaggregated this heterogeneous community and/or differentiated effects of different forms of discrimination. Using the first nationally representative data on AA immigrants in US, this study examines whether perceived racial discrimination, perceived language discrimination, and vicarious racism experiences increase the risk of psychiatric disorder for different Asian immigrant groups in the past 12 months. Results from group specific logistic regressions show that both perceived racial and language discrimination have strong deleterious effects on mental health only for Filipinos, while Vietnamese and Chinese are more likely to be affected by vicarious racism experiences. No significant association was found between racial discrimination and the mental health outcome for Vietnamese and Chinese. Findings were discussed in the light of inter-racial contact pattern and acculturation status for each group.

Social-Contextual Influences on Adolescent Romantic Involvement: The Constraints of Being a Numerical Minority

2009-01-01

This research explores white-black differences in adolescent heterosexual romantic involvement and how these differences are shaped by social context. We find that, parallel to patterns of marriage in adulthood, Non-Hispanic white girls are more likely to be in a romantic relationship than African American girls. This is particularly true when we focus on heterosexual romantic relationships formed with schoolmates. Among boys, African Americans are more likely to be romantically involved than Non-Hispanic whites. We investigate the contribution of two broad types of social-demographic factors to these race-ethnic differences, population composition and normative climate. We develop theory about why being a numerical minority should lead to lower levels of relationship formation, especially when interracial relationships are rare. Results support the population composition hypotheses but not the idea that race-ethnic differences arise because of differences in normative climate. PMID:20161469

To provide a database of the auricular measurements of Chinese infants born in Hong Kong. Prospective cross-sectional study. A total of 2384 healthy singleton, born consecutively at the Prince of Wales Hospital and the Union Hospital from October 1998 to September 2000, were included in the study. The range of gestation was 33-42 weeks. Measurements included ear width (EW), ear length (EL) and ear position (EP). The data show generally higher values for males in the parameters measured. When compared with previously published data for Caucasian and Jordanian term babies, Chinese babies have shorter EL. The ears were within normal position in nearly all our infants. The human ear appears to grow in a remarkably constant fashion. This study establishes the first set of gestational age-specific standard of the ear parameters for Chinese new-borns, potentially enabling early syndromal diagnosis. There are significant inter-racial differences in these ear parameters.

Historical Trends and Regional Differences in All-Cause and Amenable Mortality Among American Indians and Alaska Natives Since 1950

American Indian and Alaska Native (AI/AN) death rates declined over most of the 20th century, even before the Public Health Service became responsible for health care in 1956. Since then, rates have declined further, although they have stagnated since the 1980s. These overall patterns obscure substantial regional differences. Most significant, rates in the Northern and Southern Plains have declined far less since 1949 to 1953 than those in the East, Southwest, or Pacific Coast. Data for Alaska are not available for the earlier period, so its trajectory of mortality cannot be ascertained. Socioeconomic measures do not adequately explain the differences and rates of change, but migration, changes in self-identification as an AI/AN person, interracial marriage, and variations in health care effectiveness all appear to be implicated.

Poor sleep quality and depression negatively impact the health-related quality of life of patients with type 2 diabetes, but the combined effect of the two factors is unknown. This study aimed to assess the interactive effects of poor sleep quality and depression on the quality of life in patients with type 2 diabetes. Patients with type 2 diabetes (n = 944) completed the Diabetes Specificity Quality of Life scale (DSQL) and questionnaires on sleep quality and depression. The products of poor sleep quality and depression were added to the logistic regression model to evaluate their multiplicative interactions, which were expressed as the relative excess risk of interaction (RERI), the attributable proportion (AP) of interaction, and the synergy index (S). Poor sleep quality and depressive symptoms both increased DSQL scores. The co-presence of poor sleep quality and depressive symptoms significantly reduced DSQL scores by a factor of 3.96 on biological interaction measures. The relative excess risk of interaction was 1.08. The combined effect of poor sleep quality and depressive symptoms was observed only in women. Patients with both depressive symptoms and poor sleep quality are at an increased risk of reduction in diabetes-related quality of life, and this risk is particularly high for women due to the interaction effect. Clinicians should screen for and treat sleep difficulties and depressive symptoms in patients with type 2 diabetes.

Face-blind for other-race faces: Individual differences in other-race recognition impairments.

We report the existence of a previously undescribed group of people, namely individuals who are so poor at recognition of other-race faces that they meet criteria for clinical-level impairment (i.e., they are "face-blind" for other-race faces). Testing 550 participants, and using the well-validated Cambridge Face Memory Test for diagnosing face blindness, results show the rate of other-race face blindness to be nontrivial, specifically 8.1% of Caucasians and Asians raised in majority own-race countries. Results also show risk factors for other-race face blindness to include: a lack of interracial contact; and being at the lower end of the normal range of general face recognition ability (i.e., even for own-race faces); but not applying less individuating effort to other-race than own-race faces. Findings provide a potential resolution of contradictory evidence concerning the importance of the other-race effect (ORE), by explaining how it is possible for the mean ORE to be modest in size (suggesting a genuine but minor problem), and simultaneously for individuals to suffer major functional consequences in the real world (e.g., eyewitness misidentification of other-race offenders leading to wrongful imprisonment). Findings imply that, in legal settings, evaluating an eyewitness's chance of having made an other-race misidentification requires information about the underlying face recognition abilities of the individual witness. Additionally, analogy with prosopagnosia (inability to recognize even own-race faces) suggests everyday social interactions with other-race people, such as those between colleagues in the workplace, will be seriously impacted by the ORE in some people.

A new methodology to decorate the surface of polyimide (PI) fiber with carbon nanotubes (CNTs) has been developed in this study. This surface decoration was carried out through a surface alkali treatment, a carboxylation modification, surface functionalization with acyl chloride groups and then with amino groups, and a surface graft of CNTs onto PI fiber. Fourier-transform infrared and X-ray photoelectron spectroscopic characterizations confirmed that CNTs were chemically grafted onto the surface of PI fiber, and scanning electron microscopic observation demonstrated the fiber surface was uniformly and densely covered with CNTs. The surface energy and wettability of PI fiber were improved in the presence of CNTs on the fiber surface, which made a contribution to enhance the interfacial adhesion of PI fiber with other inorganic matrices when used as a reinforcing fiber. The application of CNTs-decorated PI fiber for the reinforcement of phosphoric acid-based geopolymers was investigated, and the results indicated that the geopolymeric composites gained a noticeable reinforcement. Compared to unreinforced geopolymer, the geopolymeric composites achieved a remarkable increase in compressive strength by 120% and in flexural strength by 283%. Fractography investigation demonstrated that the interaction adhesion between the fibers and matrix was enhanced due to the surface decoration of PI fiber with CNTs, which contributed to an improvement in fracture-energy dissipation by fiber pullout and fiber debonding from the matrix. As a result, a significant reinforcement effect on geopolymeric composites was achieved through a fiber-bridging mechanism. This study provided an effective methodology to improve the interracial bonding force for PI fiber and also proves a highly efficient application of CNTs-decorated PI fiber for the mechanical enhancement of geopolymeric composites.

After Early Autism Diagnosis: Changes in Intervention and Parent-Child Interaction.

Suma, Katharine; Adamson, Lauren B; Bakeman, Roger; Robins, Diana L; Abrams, Danielle N

2016-08-01

This study documents the relation between an autism spectrum disorder (ASD) diagnosis, increases in intervention, and changes in parent-child interaction quality. Information about intervention and observations of interaction were collected before diagnosis and a half year after diagnosis for 79 low-risk toddlers who had screened positive for ASD risk during a well-baby checkup. Children diagnosed with ASD (n = 44) were 2.69 times more likely to increase intervention hours. After ASD diagnosis, the relation between intervention and interaction quality was complex: although increases in intervention and interaction quality were only modestly related, the overall amount of intervention after diagnosis was associated with higher quality interactions. Moreover, lower quality interactions before diagnosis significantly increased the likelihood that intervention would increase post-diagnosis.

To explore the interaction of sleep quality and depression among patients with type 2 diabetes mellitus (T2DM). With multistage cluster sampling, the living quality of all participants was investigated. The indicator of interaction was calculated according to the delta method and non-conditional logistic regression model. There were 944 residents involved in the final analysis including 365 males and 579 females. The average age was (64 ± 10.2) years. The rate of poor sleep quality and poor sleep quality combined depression were 33.6% and 40.1%, respectively. Due to poor sleep quality and depression in patients with T2DM, the combined interaction index was 2.48 (95% CI 1.44-4.29), the relative excess risk was 3.42 (95% CI 2.16-4.67), and the attributable proportion was 0.51 (95% CI 0.32-0.70). An additive interaction rather than a multiplicative interaction of poor sleep quality and depression in affecting the quality of life was found in T2DM patients. When both factors existed at the same time, the interaction effect of these 2 factors was greater than the sum of the two factors.

To examine the association between marital interaction quality during daily life and subclinical cardiovascular disease (CVD). Studies have shown that marital status and quality of marriage are associated with cardiovascular health. However, little is known about the role of marital interaction quality during daily life in contributing to these effects. The sample consisted of 281 healthy, employed middle-aged adults who were married or living with a partner in a marital-like relationship (mean age = 42.0 years, 88% white, 52% men). Marital interaction quality was assessed using hourly real-time ecological momentary assessments for 4 days, with participants rating their current or recent partner interactions on positive and negative characteristics (e.g., agreeableness and conflict). Carotid artery intima-medial thickness (IMT) was assessed using ultrasound imaging. Adjusting for demographics, positive marital interaction was inversely associated with IMT (b = -0.02, F(1,275) = 9.18, p = .002), and negative marital interaction was positively associated with IMT (b = 0.02 F(1,275) = 10.29, p = .001). These associations were not accounted for by behavioral and biological CVD risk factors and were consistent across age, sex, race, and education. The associations were also independent of marital interaction frequency, nonmarital social interaction quality, and personality factors. Global reports of marital quality, in contrast, were not associated with IMT. Marital quality as measured during real-time interactions between partners was associated with subclinical CVD in healthy middle-aged adults. This study supports the use of real-time social interaction assessment for characterizing links between social relationships and cardiovascular health.

Positive expectations encourage generalization from a positive intergroup interaction to outgroup attitudes.

The current research reveals that while positive expectations about an anticipated intergroup interaction encourage generalization of positive contact to outgroup attitudes, negative expectations restrict the effects of contact on outgroup attitudes. In Study 1, when Blacks and Whites interacted with positive expectations, interaction quality predicted outgroup attitudes to a greater degree than when groups interacted with negative expectations. When expectations (Studies 2 and 3) and the actual interaction quality (Study 4) were manipulated orthogonally, negative expectations about the interaction predicted negative outgroup attitudes, regardless of actual interaction quality. By contrast, participants holding positive expectations who experienced a positive interaction expressed positive outgroup attitudes, whereas when they experienced a negative interaction, they expressed outgroup attitudes as negative as those with negative expectations. Across all four studies, positive expectations encouraged developing outgroup attitudes consistent with interaction quality. © 2014 by the Society for Personality and Social Psychology, Inc.

School-based social and emotional learning (SEL) programs are presented to educators with little understanding of the program components that have the greatest leverage for improving targeted outcomes. Conducted in the context of a randomized controlled trial, the present study used variation in treatment teachers' (N = 143) implementation of four core components of the Responsive Classroom approach to examine relations between each component and the quality of teachers' emotional, organizational, and instructional interactions in third, fourth, and fifth grade classrooms (controlling for pre-intervention interaction quality and other covariates). We also examined the extent to which these relations varied as a function of teachers' baseline levels of interaction quality. Indices of teachers' implementation of Morning Meeting, Rule Creation, Interactive Modeling, and Academic Choice were derived from a combination of teacher-reported surveys and classroom observations. Ratings of teacher-student classroom interactions were aggregated across five observations conducted throughout the school year. Structural path models indicated that teachers' use of Morning Meeting and Academic Choice related to higher levels of emotionally supportive interactions; Academic Choice also related to higher levels of instructional interactions. In addition, teachers' baseline interaction quality moderated several associations such that the strongest relations between RC component use and interaction quality emerged for teachers with the lowest baseline interaction quality. Results highlight the value of examining individual program components toward the identification of program active ingredients that can inform intervention optimization and teacher professional development.

Children's racial bias in perceptions of others' pain.

Previous research indicates that American adults, both Black and White, assume a priori that Black people feel less pain than do White people (Trawalter, Hoffman, & Waytz, 2012, PLoS One, 7[11], 1-8). The present work investigates when in development this bias emerges. Five-, 7-, and 10-year-olds first rated the amount of pain they themselves would feel in 10 situations such as biting their tongue or hitting their head. They then rated the amount of pain they believed two other children - a Black child and a White child, matched to the child's gender - would feel in response to the same events. We found that by age 7, children show a weak racial bias and that by age 10, they show a strong and reliable racial bias. Consistent with research on adults, this bias was not moderated by race-related attitudes or interracial contact. This finding is important because knowing the age of emergence can inform the timing of interventions to prevent this bias. © 2014 The British Psychological Society.

Minority Stress and Stress Proliferation Among Same-Sex and Other Marginalized Couples

PubMed Central

LeBlanc, Allen J.; Frost, David M.; Wight, Richard G.

2014-01-01

Drawing from 2 largely isolated approaches to the study of social stress—stress proliferation and minority stress—the authors theorize about stress and mental health among same-sex couples. With this integrated stress framework, they hypothesized that couple-level minority stressors may be experienced by individual partners and jointly by couples as a result of the stigmatized status of their same-sex relationship—a novel concept. They also consider dyadic minority stress processes, which result from the relational experience of individual-level minority stressors between partners. Because this framework includes stressors emanating from both status- (e.g., sexual minority) and role-based (e.g., partner) stress domains, it facilitates the study of stress proliferation linking minority stress (e.g., discrimination), more commonly experienced relational stress (e.g., conflict), and mental health. This framework can be applied to the study of stress and health among other marginalized couples, such as interracial/ethnic, interfaith, and age-discrepant couples. PMID:25663713

Rejection as a call to arms: inter-racial hostility and support for political action as outcomes of race-based rejection in majority and minority groups.

Both majority and minority group members fear race-based rejection, and respond by disparaging the groups that they expect will reject them. It is not clear, however, how this process differs in minority and majority groups. Using large representative samples of White (N= 4,618) and Māori (N= 1,163) New Zealanders, we found that perceptions of race-based rejection predicted outgroup negativity in both groups, but in different ways and for different reasons. For White (but not Māori) New Zealanders, increased intergroup anxiety partially mediated the relationship between cognitions of rejection and outgroup negativity. Māori who expected to be rejected on the basis of their race reported increased ethnic identification and, in part through this, increased support for political action benefiting their own group. This finding supports collective-action models of social change in historically disadvantaged minority groups. © 2011 The British Psychological Society.

Psychosocial Costs of Racism to Whites: Understanding Patterns among University Students

This investigation adds to the growing body of scholarship on the psychosocial costs of racism to Whites (PCRW), which refer to consequences of being in the dominant position in an unjust, hierarchical system of societal racism. Extending research that identified five distinct constellations of costs of racism (Spanierman, Poteat, Beer, & Armstrong, 2006), we used multinomial logistic regression in the current study to examine what factors related to membership in one of the five PCRW types during the course of an academic year. Among a sample of White university freshmen (n = 287), we found that (a) diversity attitudes (i.e., universal diverse orientation and unawareness of privilege) explain PCRW type at entrance; (b) PCRW type at entrance explained participation in interracial friendships at the end of the year; (c) 45% of participants changed PCRW type during the course of the year; and (d) among those who changed type, particular PCRW types at entrance resulted in greater likelihood of membership in particular PCRW types at the end of the year.

Relationship Quality and Alcohol-Related Social Reinforcement during Couples Interaction.

PubMed

Fairbairn, Catharine E; Testa, Maria

2016-01-01

Individuals who are unhappy in their intimate partnerships are at risk for developing alcohol problems. But little is known about the mechanisms underlying this link. One possibility is that couples with poor relationship quality gain more reinforcement from alcohol in certain contexts-a possibility that has never previously been empirically examined. In the current study, 304 individuals (152 couples) were assigned to receive alcohol (target BAC .08%) or a non-alcoholic beverage. They then engaged in a conflict-resolution interaction with their partners. Videotaped interactions were coded by trained observers. Results revealed a significant interaction between alcohol and relationship quality across multiple measures. Alcohol decreased negative behaviors, decreased negative reciprocity, and enhanced self-reported experience to a greater extent during interactions involving individuals reporting low relationship quality and had comparatively little effect among those reporting high relationship quality. Findings point to a potential mechanism underlying problem drinking among couples with poor relationship quality.

Maternal mental health has enduring effects on children's life chances and is a substantial cost driver for child health, education and social services. A key linking mechanism is the quality of mother-infant interaction. A body of work associates maternal depressive symptoms across the antenatal and postnatal (perinatal) period with less-than-optimal mother-infant interaction. Our study aims to build on previous research in the field through exploring the association of a maternal personality trait, interpersonal sensitivity, measured in early pregnancy, with subsequent mother-infant interaction quality. We analysed data from the Avon Longitudinal Study of Parents and Children (ALSPAC) to examine the association between antenatal interpersonal sensitivity and postnatal mother-infant interaction quality in the context of perinatal depressive symptoms. Interpersonal sensitivity was measured during early pregnancy and depressive symptoms in the antenatal year and across the first 21 months of the postnatal period. In a subsample of the ALSPAC, mother-infant interaction was measured at 12 months postnatal through a standard observation. For the subsample that had complete data at all time points (n = 706), hierarchical regression examined the contribution of interpersonal sensitivity to variance in mother-infant interaction quality. Perinatal depressive symptoms predicted little variance in mother-infant interaction. Antenatal interpersonal sensitivity explained a greater proportion of variance in mother-infant interaction quality. The personality trait, interpersonal sensitivity, measured in early pregnancy, is a more robust indicator of subsequent mother-infant-interaction quality than perinatal depressive symptoms, thus affording enhanced opportunity to identify vulnerable mother-infant relationships for targeted early intervention.

To explore the interactions of sleep quality and sleep duration and their effects on impaired fasting glucose (IFG) in Chinese adults. Cross-sectional survey. Community-based investigation in Xuzhou, China. 15 145 Chinese men and women aged 18-75 years old who fulfilled the inclusion criteria. The Pittsburgh Sleep Quality Index was used to produce sleep quality categories of good, common and poor. Fasting blood glucose levels were assessed for IFG. Sleep duration was measured by average hours of sleep per night, with categories of <6, 6-8 and >8 h. The products of sleep and family history of diabetes, obesity and age were added to the logistic regression model to evaluate the addictive interaction and relative excess risk of interaction (RERI) on IFG. The attributable proportion (AP) of the interaction and the synergy index (S) were applied to evaluate the additive interaction of two factors. Bootstrap measures were used to calculate 95% CI of RERI, AP and S. The prevalence of IFG was greatest in those with poor sleep quality and short sleep duration (OR 6.37, 95% CI 4.66 to 8.67; p<0.001) compared with those who had good sleep quality and 6-8 h sleep duration, after adjusting for confounders. After adjusting for potential confounders RERI, AP and S values (and their 95% CI) were 1.69 (0.31 to 3.76), 0.42 (0.15 to 0.61) and 2.85 (2.14 to 3.92), respectively, for the interaction between poor sleep quality and short sleep duration, and 0.78 (0.12 to 1.43), 0.61 (0.26 to 0.87) and -65 (-0.94 to -0.27) for the interaction between good sleep quality and long sleep duration. The results suggest that there are additive interactions between poor sleep quality and short sleep duration.

The quality of staff-patient interactions underpins the overall quality of patient experience and can affect other important outcomes. However no studies have been identified that comprehensively explore both the quality and quantity of interactions in general hospital settings. To quantify and characterise the quality of staff-patient interactions and to identify factors associated with negative interaction ratings. Data were gathered at two acute English NHS hospitals between March and April 2015. Six wards for adult patients participated including medicine for older people (n=4), urology (n=1) and orthopaedics (n=1). Eligible patients on participating wards were randomly selected for observation. Staff-patient interactions were observed using the Quality of Interactions Schedule. 120h of care were observed with each 2h observation session determined from a balanced random schedule (Monday-Friday, 08:00-22:00h). Multilevel logistic regression models were used to determine factors associated with negative interactions. 1554 interactions involving 133 patients were observed. The median length of interaction was 36s with a mean of 6 interactions per patient per hour. Seventy three percent of interactions were categorized as positive, 17% neutral and 10% negative. Forty percent of patients had at least one negative interaction (95% confidence interval 32% to 49%). Interactions initiated by the patient (adjusted Odds Ratio [OR] 5.30), one way communication (adjusted OR 10.70), involving two or more staff (adjusted OR 5.86 for 2 staff, 6.46 for 3+ staff), having a higher total number of interactions (adjusted OR 1.09 per unit increase), and specific types of interaction content were associated with increased odds of negative interaction (p<0.05). In the full multivariable model there was no significant association with staff characteristics, skill mix or staffing levels. Patient agitation at the outset of interaction was associated with increased odds of negative interaction in a reduced model. There was no significant association with gender, age or cognitive impairment. There was substantially more variation at ward level (variance component 1.76) and observation session level (3.49) than at patient level (0.09). These findings present a unique insight into the quality and quantity of staff-patient interactions in acute care. While a high proportion of interactions were positive, findings indicate that there is scope for improvement. Future research should focus on further exploring factors associated with negative interactions, such as workload and ward culture. Copyright © 2016 The Authors. Published by Elsevier Ltd..

Brooks, Joanna Veazey; Gorbenko, Ksenia; Bosk, Charles

Implementing quality improvement in hospitals requires a multifaceted commitment from leaders, including financial, material, and personnel resources. However, little is known about the interactional resources needed for project implementation. The aim of this analysis was to identify the types of interactional support hospital teams sought in a surgical quality improvement project. Hospital site visits were conducted using a combination of observations, interviews, and focus groups to explore the implementation of a surgical quality improvement project. Twenty-six site visits were conducted between October 2012 and August 2014 at a total of 16 hospitals that agreed to participate. All interviews were recorded, transcribed, and coded for themes using inductive analysis. We interviewed 321 respondents and conducted an additional 28 focus groups. Respondents reported needing the following types of interactional support during implementation of quality improvement interventions: (1) a critical outside perspective on their implementation progress; (2) opportunities to learn from peers, especially around clinical innovations; and (3) external validation to help establish visibility for and commitment to the project. Quality improvement in hospitals is both a clinical endeavor and a social endeavor. Our findings show that teams often desire interactional resources as they implement quality improvement initiatives. In-person site visits can provide these resources while also activating emotional energy for teams, which builds momentum and sustainability for quality improvement work. Policymakers and quality improvement leaders will benefit from developing strategies to maximize interactional learning and feedback for quality improvement teams. Further research should investigate the most effective methods for meeting these needs.

In-person site visits can provide these resources while also activating emotional energy for teams, which builds momentum and sustainability for quality improvement work. IMPLICATIONS Policymakers and quality improvement leaders will benefit from developing strategies to maximize interactional learning and feedback for quality improvement teams. Further research should investigate the most effective methods for meeting these needs. PMID:28375951

Bodily movements are an essential component of social interactions. However, the role of movement in early mother-infant interaction has received little attention in the research literature. The aim of the present study was to investigate the relationship between automatically extracted motion features and interaction quality in mother-infant interactions at 4 and 13 months. The sample consisted of 19 mother-infant dyads at 4 months and 33 mother-infant dyads at 13 months. The coding system Coding Interactive Behavior (CIB) was used for rating the quality of the interactions. Kinetic energy of upper-body, arms and head motion was calculated and used as segmentation in order to extract coarse- and fine-grained motion features. Spearman correlations were conducted between the composites derived from the CIB and the coarse- and fine-grained motion features. At both 4 and 13 months, longer durations of maternal arm motion and infant upper-body motion were associated with more aversive interactions, i.e., more parent-led interactions and more infant negativity. Further, at 4 months, the amount of motion silence was related to more adaptive interactions, i.e., more sensitive and child-led interactions. Analyses of the fine-grained motion features showed that if the mother coordinates her head movements with her infant's head movements, the interaction is rated as more adaptive in terms of less infant negativity and less dyadic negative states. We found more and stronger correlations between the motion features and the interaction qualities at 4 compared to 13 months. These results highlight that motion features are related to the quality of mother-infant interactions. Factors such as infant age and interaction set-up are likely to modify the meaning and importance of different motion features. PMID:29326626

In the ever-increasing competitive market of private hospital industry, creating a strong relationship with the customers that shapes patients' loyalty has been considered a key factor in obtaining market share. The purpose of this paper is to test a model of customer loyalty among patients of private hospitals in Iran. This cross-sectional study was carried out in Tehran, the capital of the Islamic Republic of Iran in 2010. The study samples composed of 969 patients who were consecutively selected from eight private hospitals. The survey instrument was designed based on a review of the related literature and included 36 items. Data analysis was performed using structural equation modeling. For the service quality construct, three dimensions extracted: Process, interaction, and environment. Both process and interaction quality had significant effects on perceived value. Perceived value along with the process and interaction quality were the most important antecedents of patient overall satisfaction. The direct effect of the process and interaction quality on behavioral intentions was insignificant. Perceived value and patient overall satisfaction were the direct antecedents of patient behavioral intentions and the mediators between service quality and behavioral intentions. Environment quality of service delivery had no significant effect on perceived value, overall satisfaction, and behavioral intentions. Contrary to previous similar studies, the role of service quality was investigated not in a general sense, but in the form of three types of qualities including quality of environment, quality of process, and quality of interaction.

Spirituality has demonstrated a significant impact on quality of life in nursing-home patients. Likewise, as essential aspects of spirituality, hope, self-transcendence, and meaning are found to be vital resources to nursing-home patients' global well-being. Further, nurse-patient interaction has demonstrated a powerful influence on patient's hope, self-transcendence, and meaning-in-life, as well as on anxiety and depression. The present study investigated the associations of hope, self-transcendence, meaning, and perceived nurse-patient interaction with quality of life. In a cross-sectional design, a sample of 202 cognitively intact nursing-home patients in Mid-Norway responded to the Herth Hope Index, the Self-Transcendence scale, the Purpose-in-Life test, the Nurse-Patient Interaction scale, and a one-item overall measure on quality of life. Using SPSS ordinal regression, bivariate and multivariate analyses were conducted with quality of life as dependent variable. Controlling for gender, age, and residential time, all the scales were significantly related to quality of life in the bivariate analyses. Intrapersonal self-transcendence showed an exceptional position presenting a very high odds ratio in the bivariate analysis, and also the strongest association with quality of life in multivariate analyses. Meaning and nurse-patient interaction also showed independent and significant associations with quality of life. The associations found encourage the idea that intrapersonal self-transcendence, meaning-in-life, and nurse-patient interaction are powerful health-promoting factors that significantly influence on nursing-home patients' quality of life. Therefore, pedagogical approaches for advancing caregivers' presence and confidence in health-promoting interaction should be upgraded and matured. Proper educational programs for developing interacting skills including assessing and supporting patients' intrapersonal self-transcendence and meaning-in-life should be utilised and their effectiveness evaluated. © 2016 Nordic College of Caring Science.

Self-construal, affective valence of the encounter, and quality of social interactions: Within and cross-culture examination.

In two samples, one from Greece and another from Germany, we examined relationships between self-construal, emotional experience, and the quality of social interactions. In Greece, a more collectivistic culture, the negative affect people experienced in social interactions was more weakly related to the quality of social interactions for those higher in interdependent self-construal than it was for those lower in interdependent self-construal. In Germany, a more independent culture, a contrasting pattern was observed such that the positive affect people experienced in social interaction was more strongly related to the quality of social interactions for those higher in independent self-construal than it was for those lower in independent self-construal. These findings suggest that positive and negative affect in social encounters can have different effects for persons with independent and interdependent cultural orientations within different cultural settings.

The quality of children's social interactions and their attachment security with a primary caregiver are two widely studied indices of socioemotional functioning in early childhood. Although both Bowlby and Ainsworth suggested that the parent-child interactions underlying the development of attachment security could be distinguished from other aspects of parent-child interaction (e.g., play), relatively little empirical research has examined this proposition. The aim of the current study was to explore this issue by examining concurrent relations between toddler's attachment security in the Strange Situation Procedure and quality of mother-child social interaction in a high-risk sample of toddlers characterized by prenatal cocaine exposure and low levels of maternal education. Analyses of variance suggested limited relations between attachment security and quality of social interaction. Further research examining the interrelations among various components of the parent-child relationship is needed. Copyright © 2011 Elsevier Inc. All rights reserved.

Assessing reliability of protein-protein interactions by integrative analysis of data in model organisms.

PubMed

Lin, Xiaotong; Liu, Mei; Chen, Xue-wen

2009-04-29

Protein-protein interactions play vital roles in nearly all cellular processes and are involved in the construction of biological pathways such as metabolic and signal transduction pathways. Although large-scale experiments have enabled the discovery of thousands of previously unknown linkages among proteins in many organisms, the high-throughput interaction data is often associated with high error rates. Since protein interaction networks have been utilized in numerous biological inferences, the inclusive experimental errors inevitably affect the quality of such prediction. Thus, it is essential to assess the quality of the protein interaction data. In this paper, a novel Bayesian network-based integrative framework is proposed to assess the reliability of protein-protein interactions. We develop a cross-species in silico model that assigns likelihood scores to individual protein pairs based on the information entirely extracted from model organisms. Our proposed approach integrates multiple microarray datasets and novel features derived from gene ontology. Furthermore, the confidence scores for cross-species protein mappings are explicitly incorporated into our model. Applying our model to predict protein interactions in the human genome, we are able to achieve 80% in sensitivity and 70% in specificity. Finally, we assess the overall quality of the experimentally determined yeast protein-protein interaction dataset. We observe that the more high-throughput experiments confirming an interaction, the higher the likelihood score, which confirms the effectiveness of our approach. This study demonstrates that model organisms certainly provide important information for protein-protein interaction inference and assessment. The proposed method is able to assess not only the overall quality of an interaction dataset, but also the quality of individual protein-protein interactions. We expect the method to continually improve as more high quality interaction data from more model organisms becomes available and is readily scalable to a genome-wide application.

Objectives Prior studies have established disparities by race/ethnicity and socioeconomic status (SES) in the kind, quantity, and technical quality of SLE care and outcomes. In this study we evaluate whether disparities exist in assessments of interactions with health care providers and health plans and whether such interactions affect the technical quality of SLE care. Methods Data derive from the Lupus Outcomes Study (LOS). Principal data collection is an annual structured phone interview including items from the Consumer Assessment of Health Plans and Interpersonal Processes of Care Scale measuring dimensions of health care interactions. We use general estimating equations to assess whether disparities exist by race/ethnicity and SES in being in the lowest quartile of ratings of such interactions and whether ratings in the lowest quartile of interactions are associated with technical quality of care after adjustment for sociodemographic and disease characteristics. Results In the 2012 LOS interview, there were 793 respondents, of whom 640 had ≥1 visits to their principal SLE provider. Non-white race/ethnicity and education were not associated with low ratings on any dimension of provider or system interaction; poverty was associated only with low ratings of health plan interactions. After adjustment for demographics, SLE status, and health care variables, ratings in the lowest quartile on all dimensions were associated with significantly lower technical quality of care. Conclusions Ratings in the lowest quartile on all dimensions of interactions with providers and the health care system were associated with lower technical quality of care, potentially resulting in poorer SLE outcomes.

Objectives To explore the interactions of sleep quality and sleep duration and their effects on impaired fasting glucose (IFG) in Chinese adults. Design Cross-sectional survey. Setting Community-based investigation in Xuzhou, China. Participants 15 145 Chinese men and women aged 18–75 years old who fulfilled the inclusion criteria. Primary and secondary outcome measures The Pittsburgh Sleep Quality Index was used to produce sleep quality categories of good, common and poor. Fasting blood glucose levels were assessed for IFG. Sleep duration was measured by average hours of sleep per night, with categories of <6, 6–8 and >8 h. The products of sleep and family history of diabetes, obesity and age were added to the logistic regression model to evaluate the addictive interaction and relative excess risk of interaction (RERI) on IFG. The attributable proportion (AP) of the interaction and the synergy index (S) were applied to evaluate the additive interaction of two factors. Bootstrap measures were used to calculate 95% CI of RERI, AP and S. Results The prevalence of IFG was greatest in those with poor sleep quality and short sleep duration (OR 6.37, 95% CI 4.66 to 8.67; p<0.001) compared with those who had good sleep quality and 6–8 h sleep duration, after adjusting for confounders. After adjusting for potential confounders RERI, AP and S values (and their 95% CI) were 1.69 (0.31 to 3.76), 0.42 (0.15 to 0.61) and 2.85 (2.14 to 3.92), respectively, for the interaction between poor sleep quality and short sleep duration, and 0.78 (0.12 to 1.43), 0.61 (0.26 to 0.87) and −65 (−0.94 to −0.27) for the interaction between good sleep quality and long sleep duration. Conclusions The results suggest that there are additive interactions between poor sleep quality and short sleep duration. PMID:24625639

This study examined the stability of maternal punitive/high-power discipline (PD) and inductive/authoritative discipline (ID) over the second and third years of life and the effect of maternal discipline on quality of mother-child interactions. Data from a longitudinal sample with 179 mother-toddler dyads were analyzed, and selected factors (i.e., child sex, temperament) that might moderate the association between maternal discipline and quality of mother-child interactions were also examined. Maternal discipline, quality of mother-child interactions, and temperamental moderators were measured at 16-18 months (Time 1) and 34-37 months (Time 2). Results showed that the stability of maternal use of discipline strategies over the toddler years was moderate. Lower maternal use of PD, higher maternal use of ID, and higher preference/reliance on ID (relative to PD) were associated with higher quality of mother-child interactions. Moderation effects of child temperament were also found. High ID and PD were associated with low quality of mother-child relationships in non-temperamentally difficult children but not in temperamentally difficult children.

Panning for the gold in health research: incorporating studies' methodological quality in meta-analysis.

PubMed

Johnson, Blair T; Low, Robert E; MacDonald, Hayley V

2015-01-01

Systematic reviews now routinely assess methodological quality to gauge the validity of the included studies and of the synthesis as a whole. Although trends from higher quality studies should be clearer, it is uncertain how often meta-analyses incorporate methodological quality in models of study results either as predictors, or, more interestingly, in interactions with theoretical moderators. We survey 200 meta-analyses in three health promotion domains to examine when and how meta-analyses incorporate methodological quality. Although methodological quality assessments commonly appear in contemporary meta-analyses (usually as scales), they are rarely incorporated in analyses, and still more rarely analysed in interaction with theoretical determinants of the success of health promotions. The few meta-analyses (2.5%) that did include such an interaction analysis showed that moderator results remained significant in higher quality studies or were present only among higher quality studies. We describe how to model quality interactively with theoretically derived moderators and discuss strengths and weaknesses of this approach and in relation to current meta-analytic practice. In large literatures exhibiting heterogeneous effects, meta-analyses can incorporate methodological quality and generate conclusions that enable greater confidence not only about the substantive phenomenon but also about the role that methodological quality itself plays.

The Tri-Trophic Interactions Hypothesis: Interactive Effects of Host Plant Quality, Diet Breadth and Natural Enemies on Herbivores

PubMed Central

Mooney, Kailen A.; Pratt, Riley T.; Singer, Michael S.

2012-01-01

Several influential hypotheses in plant-herbivore and herbivore-predator interactions consider the interactive effects of plant quality, herbivore diet breadth, and predation on herbivore performance. Yet individually and collectively, these hypotheses fail to address the simultaneous influence of all three factors. Here we review existing hypotheses, and propose the tri-trophic interactions (TTI) hypothesis to consolidate and integrate their predictions. The TTI hypothesis predicts that dietary specialist herbivores (as compared to generalists) should escape predators and be competitively dominant due to faster growth rates, and that such differences should be greater on low quality (as compared to high quality) host plants. To provide a preliminary test of these predictions, we conducted an empirical study comparing the effects of plant (Baccharis salicifolia) quality and predators between a specialist (Uroleucon macolai) and a generalist (Aphis gossypii) aphid herbivore. Consistent with predictions, these three factors interactively determine herbivore performance in ways not addressed by existing hypotheses. Compared to the specialist, the generalist was less fecund, competitively inferior, and more sensitive to low plant quality. Correspondingly, predator effects were contingent upon plant quality only for the generalist. Contrary to predictions, predator effects were weaker for the generalist and on low-quality plants, likely due to density-dependent benefits provided to the generalist by mutualist ants. Because the TTI hypothesis predicts the superior performance of specialists, mutualist ants may be critical to A. gossypii persistence under competition from U. macolai. In summary, the integrative nature of the TTI hypothesis offers novel insight into the determinants of plant-herbivore and herbivore-predator interactions and the coexistence of specialist and generalist herbivores.

Objective Pregnancy, birth and health complications, maternal mental health problems following preterm birth and their possible impact on early mother–infant interaction at 6 and 18 months corrected age (CA) were explored. Predictors of mother–infant interaction at 18 months CA were identified. Design and methods This prospective longitudinal and observational study included 33 preterm mother–infant (<33 gestational age (GA)) interactions at 6 and 18 months CA from a socioeconomic low-risk, middle-class sample. The Parent–Child Early Relational Assessment (PCERA) scale was used to assess the mother–infant interaction. Results ‘Bleeding in pregnancy’ predicted lower quality in preterm mother–infant interaction in 6 PCERA scales, while high ‘maternal trait anxiety’ predicted higher interactional quality in 2 PCERA scales and ‘family size’ predicted lower interactional quality in 1 PCERA scale at 18 months CA. Mothers with symptoms of post-traumatic stress reactions, general psychological distress and anxiety at 2 weeks postpartum (PP) showed significantly better outcome than mothers without symptoms in 6 PCERA subscales at 6 months CA and 2 PCERA subscales at 18 months CA. Conclusions Our study detected a correspondence between early pregnancy complications and lower quality of preterm mother–infant interaction, and an association between high levels of maternal mental health problems and better quality in preterm mother–infant interaction.

To investigate patient-professional interactions and identify the association between quality of care, productivity of patient-professional interaction, and chronically ill patients' well-being. Questionnaires were distributed to chronically ill patients [T1 (2011), 2,191/4,693 (47 %) respondents; T2 (2012), 1,722/4,350 (40 %) respondents]. Patients perceived a higher degree of productive interaction with general practitioners compared to other professionals. Bivariate analyses showed that patients' well-being at T2 was positively related to well-being at T1 (r = 0.70), quality of care (r = 0.12), and productive patient-professional interaction (r = 0.31; all p ≤ 0.001). Single status (r = -0.14), low education (r = -0.11), and female gender (r = -0.11; all p ≤ 0.001) were negatively associated with well-being. Multivariate analyses showed that after controlling for background characteristics and well-being at baseline quality of care is associated with patients' well-being at T2 (p ≤ 0.01). When productive patient-professional interactions were entered into the equation, they not only were related to patients' well-being (p ≤ 0.001) but also mediated the relationship between the quality of care and well-being. More productive patient-professional interactions were related to better well-being at T2 (B = 0.11), assuming that all other factors in the model remained constant. Productive patient-professional interactions are associated with chronically ill patients' well-being over time and mediate the relationship between well-being and quality of care. Improvement of the quality of chronic care delivery should always be accompanied by investment in the quality of relationships and communication between patients and professionals.

[Patient-doctor interaction in rehabilitation: is there a relationship between perceived interaction quality and long term treatment results?].

Dibbelt, S; Schaidhammer, M; Fleischer, C; Greitemann, B

2010-10-01

A body of evidence suggests that good interaction is crucial for high-quality medical practice and that it has a considerable impact on treatment outcomes. Less is known about the role and significance of doctor-patient interaction in rehabilitation. The study's aim was to capture perceived quality of doctor-patient interaction in rehabilitation by a rating instrument (P.A.INT-Questionnaire) and to examine the relationship between perceived quality of interaction and long-term treatment outcomes. Referring to the approach of Bensing (1990) and Rogers (1972) we defined "quality of interaction" in terms of 3 dimensions: (1) affective behaviour, i. e., empathy, positive regard and coherence; (2) instrumental behaviour: providing and collecting information, structuring and reinforcement; (3) participation and involvement of patients. 2 parallel versions of the Questionnaire were developed for patients and physicians. 7 rehabilitation clinics in north-western Germany participated in the multi-centre study. 61 doctors and their 470 patients evaluated both their shared dialogues upon admission, discharge and at least one ward round. Furthermore, patients rated their health status on admission (t0), discharge (t1) and 6 months after discharge (t2) using the IRES-3 (Indicators of Rehabilitation Status Questionnaire Version 3). (1) Comparisons of patient and physician evaluations on admission revealed the following: Affective quality of contact (empathy and coherence) was rated positively and without discrepancies by both patients and physicians. On the other hand, instrumental behaviour (information and structuring) was rated less positively by patients than by physicians. (2) Patients who rated the dialogue on admission more positively showed stronger treatment effects with respect to pain, to anxiety and depression 6 months after discharge. Also disability days decreased about 40% stronger in the group of positive raters. (3) Patient ratings of quality of interaction showed low but significant correlations with patient-related aspects like coping with disease, health-related knowledge and former positive experiences with physicians. A stepwise regression analysis revealed that interaction quality seems to contribute to enhanced treatment results independently of patients' competences. Our results suggest a positive relationship between perceived interaction quality as defined by the P.A.INT-Questionnaire and treatment effects 6 months after discharge. Comparisons of patient and physician evaluations showed that physicians seem to be successful in building relationships on the affective level but less successful on the instrumental level (i. e., information, structuring and reinforcement). Our data underline the importance of interaction quality for the success of rehabilitation and thus the importance of specific skills such as providing and collecting information, recognizing patients' concerns and goals as well as reinforcement of health-related action. This is especially important when knowledge of disease and coping with disease on patients' side is poor. Interaction quality seems to contribute to better treatment results independently of patients' competences. © Georg Thieme Verlag KG Stuttgart · New York.

[The structure of interaction in romantic relationships: hierarchical data analysis of inter-subjectivity between partners].

PubMed

Shimizu, Hiroshi; Daibo, Ikuo

2008-02-01

A hierarchical data analysis was conducted using data from couples to examine how self-reports of interactions between partners in romantic relationships predict the quality of the relationships. Whereas the social exchange theory has elucidated the quality of relationships from the individual level of subjectivity, this study focused on the structure of interactions between the partners (i.e., the frequency, strength, and diversity) through a process of inter-subjectivity at the couple level. A multilevel covariance structure analysis of 194 university students involved in romantic relationships revealed that the quality of relationships was mainly related to the strength and the diversity of interactions at the couple level, rather than the strength of interactions at the individual level. These results indicate that the inter-subjective process in romantic relationships may primarily explain the quality of relationships.

A staged theoretical model designed to explain the quality of elder caring by family members was tested. The model posits how the situational context, interactional process, and caregiving burden perceived by the caregiver affect the quality of elder caring. The purpose was to determine the amount of variance explained by the interactional process beyond that explained by the situational context and caregiving burden. Data were collected from 209 elder-caregiver dyads using interviews, observations, and caregiver self-reports. The strongest predictors of caregiving burden were the caregiver's stressful negative life events (situational context) and discrepancy between past and present image of elder (interactional process). The strongest predictors of quality of elder caring were the caregiver's perception of subjective burden and a monitoring role definition on the part of the caregiver (interactional process).

Pulse interactions affect pulse qualities during the propagation. Interactions between butterfly-shaped pulses are investigated to improve pulse qualities in the inhomogeneous media. In order to describe the interactions between butterfly-shaped pulses, analytic two-soliton solutions are derived. Based on those solutions, influences of corresponding parameters on pulse interactions are discussed. Methods to control the pulse interactions are suggested. - Highlights: • Interactions between butterfly-shaped pulses are investigated. • Methods to control the pulse interactions are suggested. • Analytic two-soliton solutions for butterfly-shaped pulses are derived.

The Role of Interactional Quality in Learning from Touch Screens during Infancy: Context Matters.

Zack, Elizabeth; Barr, Rachel

2016-01-01

Interactional quality has been shown to enhance learning during book reading and play, but has not been examined during touch screen use. Learning to apply knowledge from a touch screen is complex for infants because it involves transfer of learning between a two-dimensional (2D) screen and three-dimensional (3D) object in the physical world. This study uses a touch screen procedure to examine interactional quality measured via maternal structuring, diversity of maternal language, and dyadic emotional responsiveness and infant outcomes during a transfer of learning task. Fifty 15-month-old infants and their mothers participated in this semi-naturalistic teaching task. Mothers were given a 3D object, and a static image of the object presented on a touch screen. Mothers had 5 min to teach their infant that a button on the real toy works in the same way as a virtual button on the touch screen (or vice versa). Overall, 64% of infants learned how to make the button work, transferring learning from the touch screen to the 3D object or vice versa. Infants were just as successful in the 3D to 2D transfer direction as they were in the 2D to 3D transfer direction. A cluster analysis based on emotional responsiveness, the proportion of diverse maternal verbal input, and amount of maternal structuring resulted in two levels of interactional quality: high quality and moderate quality. A logistic regression revealed the level of interactional quality predicted infant transfer. Infants were 19 times more likely to succeed and transfer learning between the touch screen and real object if they were in a high interactional quality dyad, even after controlling for infant activity levels. The present findings suggest that interactional quality between mother and infant plays an important role in making touch screens effective teaching tools for infants' learning.

The use and abuse of religious beliefs in dividing and conquering between socially marginalized groups: the same-sex marriage debate.

PubMed

Greene, Beverly

2009-11-01

This article discusses the use and abuse of religious beliefs and their role in divide-and-conquer strategies. Divide-and-conquer strategies are engaged to disrupt potential coalitions between and among marginalized group members, specifically sexual minority groups and people of color. Tensions between these groups have been exacerbated by the debate on same-sex marriage and comparisons between the discriminatory treatment of each group. A component of this discussion includes a brief exploration of one of the historical abuses of religious doctrine used to legitimize the marginalization of people of color and sexual minorities in the United States. For African Americans, one form of marginalization was reflected in criminalizing interracial marriage, and for members of sexual minority groups, a form of marginalization is denying group members the right to marry. The author also explores culturally competent and respectful disciplinary and clinical responses to religiously derived prejudice against sexual minority group members and people of color and discusses the implications for multicultural discourse.

To provide a database of the craniofacial measurements of Chinese infants born in Hong Kong. Prospective cross-sectional study. A total of 2371 healthy singleton, born consecutively at the Prince of Wales Hospital and the Union Hospital from June 1998 to June 2000, were included in the study. The range of gestation was 33-42 weeks. Measurements included facial width (FW), facial height (FH), nasal length (NL), nasal width (NW), and length of the philtrum (PhilL). The facial, nasal, nasofacial and nasozygomatic indices were derived. The data show generally higher values for males in the parameters measured. The various indices remained remarkably constant and did not vary significantly between the two genders or with gestation. When compared with previously published data for white people term babies, Chinese babies have similar NW but shorter philtrum length. The human face appears to grow in a remarkably constant fashion as defined by the various indices of facial proportions. This study establishes the first set of gestational age-specific standard of such craniofacial parameters for Chinese new-borns, potentially enabling early syndromal diagnosis. There are significant inter-racial differences in these craniofacial parameters.

Epidemiology of Helicobacter pylori infection in Malaysia--observations in a multiracial Asian population.

PubMed

Goh, K L

2009-09-01

Observations of racial differences in the prevalence of Helicobacter pylori in Malaysia have been intriguing. The Indians and Chinese consistently have a higher prevalence compared to the Malays. The racial cohort theory has been proposed to explain these differences where transmission and perpetuation of infection takes place within a racial group rather than between races, races being separate owing to the low rate of interracial marriages. Studies have demonstrated distinctive bacterial strains between races. Phylogenetic studies have shown that H. pylori isolates amongst Chinese and Indians are distinctive while Malays have Indian and other strains suggesting a more recent acquisition of the bacterium from Indians. H. pylori is recognized as the major causative factor in peptic ulcer disease and gastric cancer. Despite the high prevalence of H. pylori, Indians have a relatively low prevalence of peptic ulcer disease and a low incidence of gastric cancer. This paradox with regards to gastric cancer has been termed the "Indian enigma". Bacterial strain differences between races may be putative but this observation may also indicate gastroprotective environmental factors or a lower genetic susceptibility to develop cancer in the Indians.

The Role of Father Involvement and Marital Satisfaction in the Development of Family Interactive Abilities: A Multilevel Approach.

The study aims to investigate the development of family interactions from pregnancy to preschool age in a longitudinal perspective, using multilevel analysis. Also, it explored the impact of couple relationship and father involvement in childcare on the developmental trend of the quality of mother-father-child interactions. One hundred and three primiparous families were assessed at 7th month of pregnancy, 4th, 9th, and 18th months of child's life and during preschool age (36-48th), using the observational procedure named, Lausanne Trilogue Play. Parents' perception of marital satisfaction was assessed with the Dyadic Adjustment Scale at each point of measure; moreover, in the postnatal assessment, parents completed the Father Involvement Questionnaire. Results showed that family interactions increase over time. Secondly, a decrease of marital adjustment is associated with an improvement of the quality of family interactions. Moreover, father involvement predicts the quality of family interactions from the earliest stages of child's life. In a longitudinal perspective, family interactions and marital quality show opposite developmental trends and father's involvement represents a particularly important feature of the family.

The article aims to study mother-child and father-child interactions with 24-month-old children during feeding, considering the possible influence of time spent by the parent with the child, the infantile temperament, and the parental psychological profile. The families were recruited from 12 preschools in Italy (N = 77 families). Through an observation of the feeding [Scala di Valutazione dell'Interazione Alimentare (SVIA - Feeding Scale; I. Chatoor et al., ; L. Lucarelli et al., )], self-reporting [Symptom Checklist-90-Revised (SCL-90-R; L.R. Derogatis, ), and report-form questionnaires [Italian Questionnaires on Temperament (QUIT; G. Axia, )], and information provided by the parents about the amount of time spent with their children, results showed that the overall quality of father-child interactions during feeding is lower than that of mother-child interactions. Fathers showed higher psychological symptoms than did mothers. No associations were found between the fathers' psychopathological risk and the quality of interactions with their children during feeding. Mothers' psychopathological risks predicted less contingent exchanges interactions with their children during feeding. Children's temperaments significantly influence mother-child interactions, but no association exists between maternal involvement and the quality of interactions with their children. Paternal involvement predicts a better quality of father-infant interactions when associated with a child's higher scores on Social Orientation. The quality of parents' interactions with their children during feeding are impacted by different issues originating from the parent's psychological profile, the degree of involvement, and from the child's temperament. © 2014 Michigan Association for Infant Mental Health.

Pregnancy, birth and health complications, maternal mental health problems following preterm birth and their possible impact on early mother-infant interaction at 6 and 18 months corrected age (CA) were explored. Predictors of mother-infant interaction at 18 months CA were identified. This prospective longitudinal and observational study included 33 preterm mother-infant (<33 gestational age (GA)) interactions at 6 and 18 months CA from a socioeconomic low-risk, middle-class sample. The Parent-Child Early Relational Assessment (PCERA) scale was used to assess the mother-infant interaction. 'Bleeding in pregnancy' predicted lower quality in preterm mother-infant interaction in 6 PCERA scales, while high 'maternal trait anxiety' predicted higher interactional quality in 2 PCERA scales and 'family size' predicted lower interactional quality in 1 PCERA scale at 18 months CA. Mothers with symptoms of post-traumatic stress reactions, general psychological distress and anxiety at 2 weeks postpartum (PP) showed significantly better outcome than mothers without symptoms in 6 PCERA subscales at 6 months CA and 2 PCERA subscales at 18 months CA. Our study detected a correspondence between early pregnancy complications and lower quality of preterm mother-infant interaction, and an association between high levels of maternal mental health problems and better quality in preterm mother-infant interaction.

It is not clearly understood how the quality of early mother-child interaction influences language development in very-low-birth-weight children (VLBW). We aim to analyze associations between early language and the quality of mother-child interaction, and, the predictive value of the features of early mother-child interaction on language development at 24 months of corrected age in VLBW children. A longitudinal prospective follow-up study design was used. The participants were 28 VLBW children and 34 full-term controls. Language development was measured using different methods at 6, 12 and at 24 months of age. The quality of mother-child interaction was assessed using PC-ERA method at 6 and at 12 months of age. Associations between the features of early interaction and language development were different in the groups of VLBW and full-term children. There were no significant correlations between the features of mother-child interaction and language skills when measured at the same age in the VLBW group. Significant longitudinal correlations were detected in the VLBW group especially if the quality of early interactions was measured at six months and language skills at 2 years of age. However, when the predictive value of the features of early interactions for later poor language performance was analyzed separately, the features of early interaction predicted language skills in the VLBW group only weakly. The biological factors may influence on the language development more in the VLBW children than in the full-term children. The results also underline the role of maternal and dyadic factors in early interactions. Copyright © 2014 Elsevier Ltd. All rights reserved.

To determine if the quality of CPR had a significant interaction with the primary study intervention in the NIH PRIMED trial. The public access database from the NIH PRIMED trial was accessed to determine if there was an interaction between quality of CPR performance, intervention, and outcome (survival to hospital discharge with modified Rankin Score (mRS) ≤ 3). Multi-centered prehospital care systems across North America. Of 8719 adult patients enrolled, CPR quality was electronically recorded for compression rate, depth, and fraction in 6199 (71.1%), 3750 (43.0%) and 6204 (71.2%) subjects, respectively. "Acceptable" quality CPR was defined prospectively as simultaneous provision of a compression rate of 100/min (± 20%), depth of 5 cm (± 20%) and fraction of > 50%. Significant interaction was considered as p < 0.05. Standard CPR with an activated versus sham (inactivated) ITD. Overall, 848 and 827 patients, respectively, in the active and sham-ITD groups had "acceptable" CPR quality performed (n = 1675). There was a significant interaction between the active and sham-ITD and compression rate, depth and fraction as well as their combinations. The strongest interaction was seen with all three parameters combined (unadjusted and adjusted interaction p-value, < 0.001). For all presenting rhythms, when "acceptable" quality of CPR was performed, use of an active-ITD increased survival to hospital discharge with mRS ≤ 3 compared to sham (61/848 [7.2%] versus 34/827 [4.1%], respectively; p = 0.006). The opposite was true for patients that did not receive "acceptable" quality of CPR. In those patients, use of an active - ITD led to significantly worse survival to hospital discharge with mRS ≤ 3 compared to sham (34/1012 [3.4%] versus 62/1061 [5.8%], p = 0.007). There was a statistically significant interaction between the quality of CPR provided, intervention, and survival to hospital discharge with mRS ≤ 3 in the NIH PRIMED trial. Quality of CPR delivered can be an underestimated effect modifier in CPR clinical trials. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The role of mother-infant interaction quality is studied in the relation between prenatal maternal emotional symptoms and child behavioral problems. Healthy pregnant, Dutch women (N = 96, M = 31.6, SD = 3.3) were allocated to the "exposed group" (n = 46), consisting of mothers with high levels of prenatal feelings of anxiety and depression, or the "low-exposed group" (n = 50), consisting of mothers with normal levels of depressive or anxious symptoms during pregnancy. When the children (49 girls, 47 boys) were 23 to 60 months of age (M = 39.0, SD = 9.6), parents completed the Child Behavior Checklist (T.M. Achenbach & L.A. Rescorla, ), and mother-child interaction quality during a home visit was rated using the Emotional Availability Scales. There were no differences in mother-child interaction quality between the prenatally exposed and low-exposed groups. Girls exposed to high prenatal emotional symptoms showed more internalizing problems, if maternal interaction quality was less optimal. No significant effects were found for boys. © 2017 Michigan Association for Infant Mental Health.

Objective The chronic care model is an increasingly used approach to improve the quality of care through system changes in care delivery. While theoretically these system changes are expected to increase productive patient–professional interaction empirical evidence is lacking. This study aims to identify the influence of quality of care on productive patient–professional interaction. Setting Longitudinal study in 18 Dutch regions. Participants Questionnaires were sent to all 5076 patients participating in 18 Disease Management Programmes (DMPs) in 2010 (2676 (53%) respondents). One year later (T1), 4693 patients still participating in the DMPs received a questionnaire (2191 (47%) respondents) and 2 years later (in 2012; T2) 1722 patients responded (out of 4350; 40% response). Interventions DMPs Primary outcome measure Patients’ perceptions of the productivity of interactions (measured as relational coordination/coproduction of care) with professionals. Patients were asked about communication dimensions (frequent, accurate, and problem-solving communication) and relationship dimensions (shared goals and mutual respect). Findings After controlling for background characteristics these results clearly show that quality of chronic care (T0), first-year changes in quality of chronic care (T1—T0) and second-year changes in quality of chronic care (T2—T1) predicted productive interactions between patients and professionals at T2 (all at p≤0.001). Furthermore, we found a negative relationship between lower educational level and productive interactions between patients and professionals 2 years later. Conclusions We can conclude that successfully dealing with the consequences of chronic illnesses requires proactive patients who are able to make productive decisions together with their healthcare providers. Since patients and professionals share responsibility for management of the chronic illness, they must also share control of interactions and decisions. The importance of patient-centeredness is growing and this study reports a first example of how quality of chronic care stimulates productive interactions between patients and professionals.

Wen, Xiaozhong; Shenassa, Edmond D

To conduct the first study to examine potential interaction between parenting style and neighborhood quality on the risk of adolescent regular smoking. We analyzed data from a nationally representative sample of U.S. adolescents (n = 1,213 pairs of adolescents and their parents) who participated in the Panel Study of Income Dynamics during 2002-2003. Regular smoking behavior and parental monitoring level were reported by adolescents. Parenting style (i.e., authoritative, authoritarian, permissive, and uninvolved) was defined by cross-classifying self-reported parental warmth and control. Based on parents' perceived neighborhood quality regarding raising children, neighborhoods were identified as either higher quality or lower quality. Adolescents in lower-quality neighborhoods were more likely to be regular smokers (13.7% vs. 8.5%; adjusted odds ratio [AOR] = 1.93, 95% CI = 1.02-3.65) than those in higher-quality neighborhoods. In lower-quality neighborhoods, adolescents of authoritarian parents (16.9%; AOR = 10.97, 95% CI = 3.36-35.84) were more likely and those of uninvolved parents (20.3%; AOR = 3.47, 95% CI = 0.91-13.17) were marginally more likely to be regular smokers than those of authoritative parents (4.3%). However, among adolescents in higher-quality neighborhoods, parenting style was independent of the risk of regular smoking. There was marginally significant interaction between authoritarian parenting style and neighborhood quality. Parental monitoring was associated with reduced risk of adolescent smoking, regardless of neighborhood quality. There was no interaction between parental monitoring and neighborhood quality. Authoritative parenting is associated with reduced risk of adolescent regular smoking in lower-quality neighborhoods but not in higher-quality neighborhoods. Authoritative parenting style and parental monitoring may buffer adverse influences of low-quality neighborhood.

To test and refine a model examining relationships among leadership, interactional justice, quality of the nursing work environment, safety climate and patient and nurse safety outcomes. The quality of nursing work environments may pose serious threats to patient and nurse safety. Justice is an important element in work environments that support safety initiatives yet little research has been done that looks at how leader interactional justice influences safety outcomes. A cross-sectional survey was conducted with 600 acute care registered nurses (RNs) to test and refine a model linking interactional justice, the quality of nurse leader-nurse relationships, work environment and safety climate with patient and nurse outcomes. In general the hypothesized model was supported. Resonant leadership and interactional justice influenced the quality of the leader-nurse relationship which in turn affected the quality of the work environment and safety climate. This ultimately was associated with decreased reported medication errors, intentions to leave and emotional exhaustion. Quality relationships based on fairness and empathy play a pivotal role in creating positive safety climates and work environments. To advocate for safe work environments, managers must strive to develop high-quality relationships through just leadership practices. © 2010 The Authors.

Chronically ill patients' self-management abilities to maintain overall well-being: what is needed to take the next step in the primary care setting?

PubMed

Cramm, Jane Murray; Nieboer, Anna Petra

2015-09-15

Although widespread problems in patient-professional interaction and insufficient support of patients' self-management abilities have been recognized, research investigating the relationships among care quality, productive interaction, and self-management abilities to maintain overall well-being is lacking. Furthermore, studies have revealed differences in these characteristics among certain groups (e.g., less-educated and older patients). This longitudinal study thus aimed to identify relationships among background characteristics, quality of care, productivity of patient-professional interaction, and self-management abilities to maintain overall well-being in chronically ill patients participating in 18 Dutch disease management programs. This longitudinal study included patients participating in 18 Dutch disease management programs. Surveys were administered in 2011 (T1; n = 2191 (out of 4693), 47 % response rate) and 2012 (T2: n = 1722 (out of 4350), 40 % response rate). A total of 1279 patients completed questionnaires at both timepoints (T1 and T2) (27 % response rate). Self-management abilities to maintain well-being were measured using the short (18-item) version of the Self-Management Ability Scale (SMAS-S), patients' perceptions of the productivity of interactions with health care professionals were assessed with the relational coordination instrument and the short (11-item) version of the Patient Assessment of Chronic Illness Care (PACIC-S) was used to assess patients' perceptions of the quality of chronic care delivery. Perceived and objective quality of care and the productivity of patient-professional interaction were found to be related to patients' self-management abilities to maintain overall well-being. These abilities were related negatively to and significantly predicted by low educational level, single status, and older age, despite the mediating role of productive interaction in their relationship with patients' perceptions of care quality. These findings suggest that patient-professional interaction is not yet sufficiently productive to successfully protect against the deterioration of self-management abilities in some groups of chronically ill patients, although such interaction and high-quality care are important factors in such protection. Improvement of the quality of chronic care delivery should thus always be accompanied by investment in high-quality communication and patient-professional relationships.

Two studies found positive relationships between the ability to manage emotions and the quality of social interactions, supporting the predictive and incremental validity of an ability measure of emotional intelligence, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). In a sample of 118 American college students (Study 1), higher scores on the managing emotions subscale of the MSCEIT were positively related to the quality of interactions with friends, evaluated separately by participants and two friends. In a diary study of social interaction with 103 German college students (Study 2), managing emotions scores were positively related to the perceived quality of interactions with opposite sex individuals. Scores on this subscale were also positively related to perceived success in impression management in social interactions with individuals of the opposite sex. In both studies, the main findings remained statistically significant after controlling for Big Five personality traits.

Preterm birth may leave long-term effects on the interactions between caregivers and children. Language skills are sensitive to the quality of caregiver-child interactions. Compare the quality of caregiver-child play interactions in toddlers born preterm (PT) and full term (FT) at age 22months (corrected for degree of prematurity) and evaluate the degree of association between caregiver-child interactions, antecedent demographic and language factors, and subsequent language skill. A longitudinal descriptive cohort study. 39 PT and 39 FT toddlers individually matched on sex and socioeconomic status (SES). The outcome measures were dimensions of caregiver-child interactions, rated from a videotaped play session at age 22months in relation to receptive language assessments at ages 18 and 36months. Caregiver intrusiveness was greater in the PT than FT group. A composite score of child interactional behaviors was associated with a composite score of caregiver interactional behaviors. The caregiver composite measure was associated with later receptive vocabulary at 36months. PT-FT group membership did not moderate the association between caregiver interactional behavior and later receptive vocabulary. The quality of caregiver interactional behavior had similar associations with concurrent child interactional behavior and subsequent language outcome in the PT and FT groups. Greater caregiver sensitivity/responsiveness, verbal elaboration, and less intrusiveness support receptive language development in typically developing toddlers and toddlers at risk for language difficulty.

Williford, Amanda P.; Maier, Michelle F.; Downer, Jason T.; Pianta, Robert C.; Howes, Carolee

2015-01-01

This study examined the quality of preschool classroom experiences through the combination of teachers’ interactions at the classroom level and children’s individual patterns of engagement in predicting children’s gains in school readiness. A sample of 605 children and 309 teachers participated. The quality of children’s engagement and teacher interactions was directly observed in the classroom setting, and direct assessments of children’s school readiness skills were obtained in the fall and again in the spring. The quality of teacher interactions was associated with gains across all school readiness skills. The effect of children’s individual classroom engagement on their gains in school readiness skills (specifically phonological awareness and expressive vocabulary) was moderated by classroom level teacher interactions. The results suggest that if teachers provide highly responsive interactions at the classroom level, children may develop more equitable school readiness skills regardless of their individual engagement patterns.

To explore the effects related to quality and duration of sleep and their interactions on the prevalence of type-2 diabetes (T2DM). 9 622 people aged 18 years and over were recruited for our cross-sectional study during March 2013 to May 2013. Unconditional logistic regression was used to analyze the relationship between quality and duration of sleep on T2DM. Bootstrap was used to calculate the relative excess risk of interaction (RERI), the attributable proportion (AP) of interaction and the synergy index (SI). 95% confidence intervals (CI) of RERI, AP and SI were estimated. Concerning the comparison between cases and controls on both individual and total scores, other scores were all significantly different (P < 0.01), except for two items (time for falling asleep and drugs for hypnosis). The prevalence of T2DM in volunteers with poor sleeping quality was higher than that in volunteers with good sleeping quality (P < 0.01). Individuals with sleep duration <6 hours had a higher prevalence of T2DM, when compared with individuals with sleep duration of 6-8 hours (P < 0.01). After adjusting for age, gender, level of education, occupation, family history of diabetes, status on cigarette smoking, alcohol intake, physical activities and body mass index (BMI), the prevalence of T2DM appeared the highest in those with poor sleeping quality and short duration (OR = 4.78, 95% CI:3.32-6.99; P < 0.01), when compared with those who had good sleep quality and 6-8 h sleep duration. The risk of T2DM still increased in people who had poor sleep or long duration (OR = 1.92, 95% CI:1.18-3.31; P < 0.01). Values of RERI, AP and SI (with 95% CI) were 2.33 (1.23-8.79), 0.67(0.21-0.83) and 6.87 (2.33-10.75), respectively, for the interaction between poor sleep quality and short sleep duration, while 0.33 (-0.12-1.13), 0.17 (-0.03-0.51), 1.56 (0.76-2.74) for the interaction between good sleep quality and long sleep duration. Our results suggested that there were additive interactions between poor quality and shorter duration of sleep.

Eco-evolutionary processes affecting plant-herbivore interactions during early community succession.

PubMed

Howard, Mia M; Kalske, Aino; Kessler, André

2018-06-01

The quality and outcome of organismal interactions are not only a function of genotypic composition of the interacting species, but also the surrounding environment. Both the strength and direction of natural selection on interacting populations vary with the community context, which itself is changed by these interactions. Here, we test for the role of interacting evolutionary and ecological processes in plant-herbivore interactions during early community succession in the tall goldenrod, Solidago altissima. We use surveys in a large-scale field experiment with repeated plots representing 6 years of early oldfield succession and reciprocal transplant common garden experiments to test for the relative importance of rapid evolution (genetic) and environmental changes (soil quality) in affecting mean plant resistance and growth phenotypes during community succession. While plant growth varied strongly with soil quality over the first 5 years of agricultural abandonment, plant secondary metabolism, and herbivore resistance varied minimally with the soil environment. Instead, mean composition and abundance of plant secondary compound bouquets differed between S. altissima plants from populations collected in communities in the first ("early") and sixth ("intermediate") years of oldfield succession, which was reflected in the feeding preference of the specialist herbivore, Trirhabda virgata, for early succession lines. Moreover, this preference was most pronounced on poorer quality, early succession soils. Overall, our data demonstrate that plant quality varies for insect herbivores during the course of early succession and this change is a combination of altered genotypic composition of the population and phenotypic plasticity in different soil environments.

Qualities of Peer Relations on Social Networking Websites: Predictions from Negative Mother-Teen Interactions

Szwedo, David E.; Mikami, Amori Yee; Allen, Joseph P.

2010-01-01

This study examined associations between characteristics of teenagers’ relationships with their mothers and their later socializing behavior and peer relationship quality online. At age 13, teenagers and their mothers participated in an interaction in which mothers’ and adolescents’ behavior undermining autonomy and relatedness was observed, and indicators of teens’ depressive symptoms and social anxiety were assessed. At age 20, youth self-reported on their online behaviors, youths’ social networking webpages were observationally coded to assess peer relationship quality online, and symptoms of depression and social anxiety were reassessed. Results suggested that problematic mother-teen relationships were predictive of youths’ later preference for online communication and greater likelihood of forming a friendship with someone met online, yet poorer quality in online relationships. Findings are discussed within a developmental framework suggesting the importance of considering youths’ family interactions during early adolescence as predictors of future online socializing behavior and online interactions with peers.

Analysis of psychological factors for quality assessment of interactive multimodal service

NASA Astrophysics Data System (ADS)

Yamagishi, Kazuhisa; Hayashi, Takanori

2005-03-01

We proposed a subjective quality assessment model for interactive multimodal services. First, psychological factors of an audiovisual communication service were extracted by using the semantic differential (SD) technique and factor analysis. Forty subjects participated in subjective tests and performed point-to-point conversational tasks on a PC-based TV phone that exhibits various network qualities. The subjects assessed those qualities on the basis of 25 pairs of adjectives. Two psychological factors, i.e., an aesthetic feeling and a feeling of activity, were extracted from the results. Then, quality impairment factors affecting these two psychological factors were analyzed. We found that the aesthetic feeling is mainly affected by IP packet loss and video coding bit rate, and the feeling of activity depends on delay time and video frame rate. We then proposed an opinion model derived from the relationships among quality impairment factors, psychological factors, and overall quality. The results indicated that the estimation error of the proposed model is almost equivalent to the statistical reliability of the subjective score. Finally, using the proposed model, we discuss guidelines for quality design of interactive audiovisual communication services.

The purpose of the current study was to predict the development of aggressive behavior from young children’s respiratory sinus arrhythmia (RSA) and environmental quality. In a longitudinal sample of 213 children, baseline RSA, RSA suppression in response to a film of crying babies, and a composite measure of environmental quality (incorporating socioeconomic status and marital adjustment) were measured, and parent-reported aggression was assessed from 18 to 54 months of age. Predictions based on biological sensitivity-to-context/differential susceptibility and diathesis-stress models, as well as potential moderation by child sex, were examined. The interaction of baseline RSA with environmental quality predicted the development (slope) and 54-month intercept of mothers’ reports of aggression. For girls only, the interaction between baseline RSA and environmental quality predicted the 18-month intercept of fathers’ reports. In general, significant negative relations between RSA and aggression were found primarily at high levels of environmental quality. In addition, we found a significant Sex × RSA interaction predicting the slope and 54-month intercept of fathers’ reports of aggression, such that RSA was negatively related to aggression for boys but not for girls. Contrary to predictions, no significant main effects or interactions were found for RSA suppression. The results provide mixed but not full support for differential susceptibility theory and provide little support for the diathesis-stress model. PMID:22182294

In Your 20s it’s Quantity, in Your 30s it’s Quality: The Prognostic Value of Social Activity Across 30 Years of Adulthood

Social connection, a leading factor in the promotion of health, well-being, and longevity, requires social knowledge and the capacity to cultivate intimacy. Lifespan development theorists have speculated that social information-seeking goals, emphasized at the beginning of early adulthood, give way to emotional closeness goals in later stages of early adulthood. Drawing on developmental theory (Baltes, 1997; Baltes & Carstensen, 2003), this 30-year prospective study assessed social activity at age-20 and age-30 with experience sampling methods, and psychosocial outcomes (social integration, friendship quality, loneliness, depression, and psychological well-being) at age-50. Results supported the hypothesis that the quantity (but not the quality) of social interactions at age-20, and the quality (but not the quantity) of social interactions at age-30 predict midlife psychosocial outcomes. Longitudinal structural models revealed that age-20 interaction quantity had a direct, unmediated effect on age-50 social and psychological outcomes. The effects of age-20 interaction quality on midlife outcomes, on the other hand, were mediated by age-30 interaction quality. Our findings are consistent with the idea that selection and optimization serve important functions in early adulthood, and that engaging in developmentally appropriate social activity contributes to psychosocial adjustment in the decades that follow.

The purpose of the current study was to examine the mutual relationships between dyadic level (i.e., marital quality and parenting stress) and individual level factors (i.e., children and parental depressive symptoms) in families of children with Oppositional Defiant Disorder (ODD). Specifically, we explored whether marital interaction (marital quality) was associated with symptoms of child depression through parent-child interaction (parenting stress) and parent depressive symptoms. We also explored whether parent-child interaction was associated with symptoms of parent depression through marital interaction and child depressive symptoms. This study was conducted with 256 parent-child dyads, consisting of children with ODD and one of each child's parents. Participants were recruited from 14 primary schools located in northern, eastern, and southwestern China. Results revealed that marital quality predicted symptoms of child depression through the parenting stress, but not parent depressive symptoms; and parenting stress predicted symptoms of parent depression through marital quality, but not through child depressive symptoms. Also, parenting stress significantly and directly predicted parent depressive symptoms. We concluded in families of children with ODD, the association of marital interaction and parent-child interaction on both symptoms of parent and child depression highlighted the mutual effects of the couple subsystem and the parent-child subsystem. Furthermore, in regard to parental and child depressive symptoms, implications for intervention are provided. PMID:29104548

The chronic care model is an increasingly used approach to improve the quality of care through system changes in care delivery. While theoretically these system changes are expected to increase productive patient-professional interaction empirical evidence is lacking. This study aims to identify the influence of quality of care on productive patient-professional interaction. Longitudinal study in 18 Dutch regions. Questionnaires were sent to all 5076 patients participating in 18 Disease Management Programmes (DMPs) in 2010 (2676 (53%) respondents). One year later (T1), 4693 patients still participating in the DMPs received a questionnaire (2191 (47%) respondents) and 2 years later (in 2012; T2) 1722 patients responded (out of 4350; 40% response). DMPs Patients' perceptions of the productivity of interactions (measured as relational coordination/coproduction of care) with professionals. Patients were asked about communication dimensions (frequent, accurate, and problem-solving communication) and relationship dimensions (shared goals and mutual respect). After controlling for background characteristics these results clearly show that quality of chronic care (T0), first-year changes in quality of chronic care (T1-T0) and second-year changes in quality of chronic care (T2-T1) predicted productive interactions between patients and professionals at T2 (all at p≤0.001). Furthermore, we found a negative relationship between lower educational level and productive interactions between patients and professionals 2 years later. We can conclude that successfully dealing with the consequences of chronic illnesses requires proactive patients who are able to make productive decisions together with their healthcare providers. Since patients and professionals share responsibility for management of the chronic illness, they must also share control of interactions and decisions. The importance of patient-centeredness is growing and this study reports a first example of how quality of chronic care stimulates productive interactions between patients and professionals.

Interaction-focussed therapy for aphasia: Effects on communication and quality of life.

PubMed

Barnes, Scott; Nickels, Lyndsey

2017-07-06

This study examined the effects of an interaction-focussed therapy for aphasia, which involved both people with aphasia and their familiar conversation partners. It was hypothesised the interaction-focussed therapy would lead to positive changes in targeted conversation behaviours, and improved quality of life for participants with aphasia. Three people with chronic aphasia and three of their familiar conversation partners completed an 8-week interaction-focussed therapy programme. A series of single case multiple-baseline ABA experiments were conducted. Outcome measures focussed on changes in targeted behaviours between pre- and post-therapy conversation samples, and changes in quality of life. All participant dyads improved their conversations. Familiar conversation partners demonstrated significant changes in targeted behaviours, while only one participant with aphasia achieved significant improvements. There was little evidence of a positive impact on quality of life for participants with aphasia. Interaction-focussed therapy enhances everyday communication for people with aphasia and their conversation partners. However, the complex nature of learning in this intervention means that further, likely interdisciplinary work is required to better understand what mediates skill acquisition and therapeutic change and its psychosocial impact. This information is particularly important for optimising interaction-focussed therapy for people with aphasia.

Sensory impacts of food-packaging interactions.

Duncan, Susan E; Webster, Janet B

2009-01-01

Sensory changes in food products result from intentional or unintentional interactions with packaging materials and from failure of materials to protect product integrity or quality. Resolving sensory issues related to plastic food packaging involves knowledge provided by sensory scientists, materials scientists, packaging manufacturers, food processors, and consumers. Effective communication among scientists and engineers from different disciplines and industries can help scientists understand package-product interactions. Very limited published literature describes sensory perceptions associated with food-package interactions. This article discusses sensory impacts, with emphasis on oxidation reactions, associated with the interaction of food and materials, including taints, scalping, changes in food quality as a function of packaging, and examples of material innovations for smart packaging that can improve sensory quality of foods and beverages. Sensory evaluation is an important tool for improved package selection and development of new materials.

Social interactions between staff and clients with an intellectual disability contain synchronized turn-taking patterns. Synchrony can increase rapport and cooperation between individuals. This study investigated whether verbal interactional dominance and balance, an indication of attunement between staff and clients with ID, are associated with synchrony of turn-taking patterns during staff-client interactions and whether the level of dominance and balance is related to the observed quality of the social interactions. Nineteen staff members video-recorded a social interaction with one of their clients in which the client asked for support. The recordings were analyzed using Cross Recurrence Quantification Analysis and Initiative Response Analysis. Fifteen staff observers as well as client observers completed a questionnaire on the quality of the video-recorded interactions. Staff and clients' patterns of verbal interactional dominance and balance were associated with the synchrony of their turn-taking behaviors. Staff's dominance was associated with a higher level of synchrony of turn taking, whereas client's dominance was associated with a lower level of synchrony. The patterns of verbal interactional dominance and balance were associated with staff observer reports about the quality of the interactions. The study suggested that staff and clients have a tendency to be sensitive to different aspects of interactions, which in turn may have different functions.

In young children with type 1 diabetes mellitus (T1DM) parents have full responsibility for the diabetes-management of their child (e.g. blood glucose monitoring, and administering insulin). Behavioral tasks in childhood, such as developing autonomy, and oppositional behavior (e.g. refusing food) may interfere with the diabetes-management to achieve an optimal blood glucose control. Furthermore, higher blood glucose levels are related to more behavioral problems. So parents might need to negotiate with their child on the diabetes-management to avoid this direct negative effect. This interference, the negotiations, and the parent's responsibility for diabetes may negatively affect the quality of parent-child interaction. Nevertheless, there is little knowledge about the quality of interaction between parents and young children with T1DM, and the possible impact this may have on glycemic control and psychosocial functioning of the child. While widely used global parent-child interaction observational methods are available, there is a need for an observational tool specifically tailored to the interaction patterns of parents and children with T1DM. The main aim of this study is to construct a disease-specific observational method to assess diabetes-specific parent-child interaction. Additional aim is to explore whether the quality of parent-child interactions is associated with the glycemic control, and psychosocial functioning (resilience, behavioral problems, and quality of life). First, we will examine which situations are most suitable for observing diabetes-specific interactions. Then, these situations will be video-taped in a pilot study (N = 15). Observed behaviors are described into rating scales, with each scale describing characteristics of parent-child interactional behaviors. Next, we apply the observational tool on a larger scale for further evaluation of the instrument (N = 120). The parents are asked twice (with two years in between) to fill out questionnaires about psychosocial functioning of their child with T1DM. Furthermore, glycemic control (HbA1c) will be obtained from their medical records. A disease-specific observational tool will enable the detailed assessment of the quality of diabetes-specific parent-child interactions. The availability of such a tool will facilitate future (intervention) studies that will yield more knowledge about impact of parent-child interactions on psychosocial functioning, and glycemic control of children with T1DM.

Microbial assemblage as biofilm around the aquatic plant forms a firm association that largely depends upon the mutual supplies of nutrients, e.g., microbes interact with plants in an aquatic system most likely for organic carbon and oxygen, whereas plants receive defensive immunity and mineral exchange. Apart from the mutual benefits, plant-microbe interactions also influence the water quality especially at rhizosphere providing inherent ability to the aquatic system for the mitigation of pollution from the water column. The review presents and in-depth information along with certain research advancements made in the field of ecological and bio/chemical aspects of plant-microbe interactions and the underlying potential to improve water quality.

Patient-doctor interaction in rehabilitation: the relationship between perceived interaction quality and long-term treatment results.

2009-09-01

A body of evidence suggests that good interaction is crucial for high-quality medical practice and has a considerable impact on treatment outcomes. Less is known about the role and significance of doctor-patient interaction in rehabilitation. The study aim was to capture perceived quality of doctor-patient interaction in rehabilitation by a rating instrument (P.A.INT-Questionnaire. P.A.INT is the abbreviation for Patient-Arzt-Interaktion (German)) and to examine the relationship between perceived quality of interaction and long-term treatment outcomes. Referring to the approach of Bensing [Bensing JM. Doctor patient communication and the quality of care. Utrecht: NIVEL; 1990] we defined "quality of interaction" in terms of three dimensions: (1) affective behaviour, i.e. empathy, positive regard and coherence [Rogers CR. Die nicht direktive Beratung München: Kindler Studienausgabe [Counselling and psychotherapy, 1942]. Boston; 1972]; (2) instrumental behaviour: providing and collecting information, structuring and reinforcement; (3) participation and involvement of patients. Two parallel versions of the questionnaire were developed for patients and physicians. Seven rehabilitation clinics in north western Germany participated in the multi-centre study. Sixty-one doctors and their four hundred and seventy patients evaluated both their shared dialogues upon admission, discharge and ward round. Furthermore, patients rated their health status on admission (t0), discharge (t1) and six months after discharge (t2) with the IRES-3 (Indicators of Rehabilitation Status Questionnaire, Version 3). (1) Comparisons of patient and physician evaluations on admission revealed the following: affective quality of contact (empathy and coherence) was rated positively and without discrepancies by both patients and physicians. On the other hand, instrumental behaviour (information and structuring) was rated less positively by patients than by physicians. (2) Patients who rated the dialogue on admission more positively showed stronger treatment effects with respect to pain as well as to anxiety at discharge and six months after discharge. Analysis for single scales of the P.A.INT-Questionnaire revealed that this is due to affective and instrumental quality of the dialogues. Our results suggest a correlation between perceived interaction quality, as defined by our questionnaire and treatment effects six months after discharge. Comparisons of patient and physician evaluations showed that physicians seem to be successful in building relationships on the affective level, but less successful on the instrumental level (i.e. information, structuring and reinforcement). They also perceive disturbances on the relational and organisational level more strongly than patients. Our data underline the importance of interaction quality for the success of rehabilitation and thus the importance of specific skills such as providing and collecting information, recognizing patients' concerns and goals as well as reinforcement of health related action. Regular training and supervision should be provided to support physicians and to enhance their competence in dealing with patients concerns.

A new framework for interactive quality assessment with application to light field coding

Viola, Irene; Ebrahimi, Touradj

2017-09-01

In recent years, light field has experienced a surge of popularity, mainly due to the recent advances in acquisition and rendering technologies that have made it more accessible to the public. Thanks to image-based rendering techniques, light field contents can be rendered in real time on common 2D screens, allowing virtual navigation through the captured scenes in an interactive fashion. However, this richer representation of the scene poses the problem of reliable quality assessments for light field contents. In particular, while subjective methodologies that enable interaction have already been proposed, no work has been done on assessing how users interact with light field contents. In this paper, we propose a new framework to subjectively assess the quality of light field contents in an interactive manner and simultaneously track users behaviour. The framework is successfully used to perform subjective assessment of two coding solutions. Moreover, statistical analysis performed on the results shows interesting correlation between subjective scores and average interaction time.

Caregiver-Child Verbal Interactions in Child Care: A Buffer against Poor Language Outcomes when Maternal Language Input is Less

Recent research has suggested that high quality child care can buffer young children against poorer cognitive and language outcomes when they are at risk for poorer language and readiness skills. Most of this research measured the quality of parenting and the quality of the child care with global observational measures or rating scales that did not specify the exact maternal or caregiver behaviors that might be causally implicated in the buffering of these children from poor outcomes. The current study examined the actual language by the mother to her child in the home and the verbal interactions between the caregiver and child in the child care setting that might be implicated in the buffering effect of high quality childcare. The sample included 433 rural children from the Family Life Project who were in child care at 36 months of age. Even after controlling for a variety of covariates, including maternal education, income, race, child previous skill, child care type, the overall quality of the home and quality of the child care environment; observed positive caregiver-child verbal interactions in the child care setting interacted with the maternal language complexity and diversity in predicting children’s language development. Caregiver-child positive verbal interactions appeared to buffer children from poor language outcomes concurrently and two years later if children came from homes where observed maternal language complexity and diversity during a picture book task was less.

OBJECTIVE: To simplify risk assessment, we have developed a way to present critically appraised drug interaction information through a chart. DATA SOURCES: Fifty drugs most frequently prescribed by Canadian family physicians and 16 drugs and substances that frequently interact with these drugs were the basis for a literature review. Drug interaction textbooks and MEDLINE (from 1966 to 1994) were searched for documented interactions. Reports of additive effects and animal or in vitro studies were excluded. STUDY SELECTION: All reports of interactions were evaluated for clinical effect, clinical significance, and quality of evidence. SYNTHESIS: Of the 464 drug-drug or drug-substance pairs evaluated, 387 (83.4%) demonstrated an interaction, 59 (12.7%) documented no effect, and 18 (3.9%) pairs had conflicting evidence. Five percent of interactions were of major clinical significance; only 1.3% were of major clinical significance and supported by good-quality evidence. By using symbols, colours, and legends in a "grid-map" format, a large amount of drug interaction information was reduced to a single-page chart suitable for a desk reference or wall mounting. CONCLUSIONS: Our chart organizes a large amount of drug interaction information in a format that allows for rapid appreciation of outcome, clinical significance, and quality of evidence.

Food-packaging interactions influencing quality and safety.

PubMed

Hotchkiss, J H

1997-01-01

Interactions between foods and packaging can be detrimental to quality and/or safety. Changes in product flavour due to aroma sorption and the transfer of undesirable flavours from packaging to foods are important mechanisms of deterioration when foods are packaged in polymer-based materials. Careful consideration must be given to those factors affecting such interactions when selecting packaging materials in order to maximize product quality, safety, and shelf-life while minimizing undesirable changes. Product considerations include sensitivity to flavour and related deteriorations, colour changes, vitamin loss, microbial activity, and amount of flavour available. Storage considerations include temperature, time, and processing method. Polymer considerations include type of polymer and processing method, volume or mass of polymer to product ratio, and whether the interaction is Fickian or non-Fickian. Methodology to determine the extent of such interactions must be developed. Direct interactions between food and packaging are not necessarily detrimental. The same principles governing undesirable interactions can be used to affect desirable outcomes. Examples include films which directly intercept or absorb oxygen, inhibit microorganisms, remove undesirable flavours by sorption, or indicate safety and product shelf-life.

Consumer-Resource Dynamics: Quantity, Quality, and Allocation

PubMed Central

Getz, Wayne M.; Owen-Smith, Norman

Background The dominant paradigm for modeling the complexities of interacting populations and food webs is a system of coupled ordinary differential equations in which the state of each species, population, or functional trophic group is represented by an aggregated numbers-density or biomass-density variable. Here, using the metaphysiological approach to model consumer-resource interactions, we formulate a two-state paradigm that represents each population or group in a food web in terms of both its quantity and quality. Methodology and Principal Findings The formulation includes an allocation function controlling the relative proportion of extracted resources to increasing quantity versus elevating quality. Since lower quality individuals senesce more rapidly than higher quality individuals, an optimal allocation proportion exists and we derive an expression for how this proportion depends on population parameters that determine the senescence rate, the per-capita mortality rate, and the effects of these rates on the dynamics of the quality variable. We demonstrate that oscillations do not arise in our model from quantity-quality interactions alone, but require consumer-resource interactions across trophic levels that can be stabilized through judicious resource allocation strategies. Analysis and simulations provide compelling arguments for the necessity of populations to evolve quality-related dynamics in the form of maternal effects, storage or other appropriate structures. They also indicate that resource allocation switching between investments in abundance versus quality provide a powerful mechanism for promoting the stability of consumer-resource interactions in seasonally forcing environments. Conclusions/Significance Our simulations show that physiological inefficiencies associated with this switching can be favored by selection due to the diminished exposure of inefficient consumers to strong oscillations associated with the well-known paradox of enrichment. Also our results demonstrate how allocation switching can explain observed growth patterns in experimental microbial cultures and discuss how our formulation can address questions that cannot be answered using the quantity-only paradigms that currently predominate.

2008-01-01

Variation between individuals is an essential component of natural selection and evolutionary change, but it is only recently that the consequences of persistent differences between individuals on population dynamics have been considered. In particular, few authors have addressed whether interactions exist between individual quality and environmental variation. In part, this is due to the difficulties of collecting sufficient data, but also the challenge of defining individual quality. Using a long-established study population of red deer, Cervus elaphus, inhabiting the North Block of the Isle of Rum, and three quality measures, this paper investigates how differences in maternal quality affect variation in birth body mass and date, as population density varies, and how this differs depending on the sex of the offspring and the maternal quality measure used. Significant interactions between maternal quality, measured as a hind's total contribution to population growth, and population density are reported for birth mass, but only for male calves. Analyses using dominance or age at primiparity to define maternal quality showed no significant interactions with population density, highlighting the difficulties of defining a consistent measure of individual quality.

Previous studies demonstrated conflicting results about the association of sleep duration and hypertension. Given the potential relationship between sleep quality and hypertension, this study aimed to investigate the interaction of self-reported sleep duration and sleep quality on hypertension prevalence in adult Chinese males. We undertook a cross-sectional analysis of 4144 male subjects. Sleep duration were measured by self-reported average sleep time during the past month. Sleep quality was evaluated using the standard Pittsburgh Sleep Quality Index. Hypertension was defined as blood pressure level ≥140/90 mm Hg or current antihypertensive treatment. The association between hypertension prevalence, sleep duration, and sleep quality was analyzed using logistic regression after adjusting for basic cardiovascular characteristics. Sleep duration shorter than 8 hours was found to be associated with increased hypertension, with odds ratios and 95% confidence intervals (CIs) of 1.25 (95% CI, 1.03-1.52) for 7 hours, 1.41 (95% CI, 1.14-1.73) for 6 hours, and 2.38 (95% CI, 1.81-3.11) for <6 hours. Using very good sleep quality as the reference, good, poor, and very poor sleep quality were associated with hypertension, with odds ratios of 1.20 (95% CI, 1.01-1.42), 1.67 (95% CI, 1.32-2.11), and 2.32 (95% CI, 1.67-3.21), respectively. More importantly, further investigation of the association of different combinations of sleep duration and quality in relation to hypertension indicated an additive interaction. There is an additive interaction of poor sleep quality and short sleep duration on hypertension prevalence. More comprehensive measurement of sleep should be performed in future studies.

Relations among early adolescents' parent-adolescent attachment, perceived social competence, and friendship quality.

Boling, Melissa W; Barry, Carolyn McNamara; Kotchick, Beth A; Lowry, Jen

2011-12-01

To assess whether the relation between attachment and friendship quality may be explained by social competence, 113 students in Grades 7 and 8 from the Baltimore metropolitan area completed self-report questionnaires on the variables of interest. In hierarchical regression analyses, both maternal Affective Quality of Attachment and the interaction of School with paternal Affective Quality of Attachment predicted social competence. Also, the interaction of School with paternal Affective Quality of Attachment predicted negative friendship features, whereas social competence predicted positive friendship features. These findings provide support for a pathway between adolescents' attachment to both parents and adolescents' perceived social competence and, in turn, their friendship quality.

This study evaluated the quality of Web-based information on cannabis use and addiction and investigated particular content quality indicators. Three keywords ("cannabis addiction," "cannabis dependence," and "cannabis abuse") were entered into two popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability, and content quality. "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. Of the 94 Websites identified, 57 were included. Most were commercial sites. Based on outcome measures, the overall quality of the sites turned out to be poor. A global score (the sum of accountability, interactivity, content quality and esthetic criteria) appeared as a good content quality indicator. While cannabis education Websites for patients are widespread, their global quality is poor. There is a need for better evidence-based information about cannabis use and addiction on the Web.

Shomaker, Lauren B.; Furman, Wyndol

2010-01-01

This study examined how current parent-adolescent relationship qualities and adolescents’ representations of relationships with parents were related to friendship interactions in 200 adolescent-close friend dyads. Adolescents and friends were observed discussing problems during a series of structured tasks. Negative interactions with mothers were significantly related to adolescents’ greater conflict with friends, poorer focus on tasks, and poorer communication skills. Security of working models (as assessed by interview) was significantly associated with qualities of friendship interactions, whereas security of attachment styles (as assessed by questionnaire) was not. More dismissing (vs. secure) working models were associated with poorer focus on problem discussions and weaker communication skills with friends, even after accounting for gender differences and current parent-adolescent relationship qualities. We discuss possible mechanisms for the observed links between dimensions of parent-adolescent relationships and friendships. We also consider methodological and conceptual differences between working model and style measures of attachment representations. PMID:20174459

Interaction between bacterial outer membrane proteins and periplasmic quality control factors: a kinetic partitioning mechanism.

The OMPs (outer membrane proteins) of Gram-negative bacteria have to be translocated through the periplasmic space before reaching their final destination. The aqueous environment of the periplasmic space and high permeability of the outer membrane engender such a translocation process inevitably challenging. In Escherichia coli, although SurA, Skp and DegP have been identified to function in translocating OMPs across the periplasm, their precise roles and their relationship remain to be elucidated. In the present paper, by using fluorescence resonance energy transfer and single-molecule detection, we have studied the interaction between the OMP OmpC and these periplasmic quality control factors. The results of the present study reveal that the binding rate of OmpC to SurA or Skp is much faster than that to DegP, which may lead to sequential interaction between OMPs and different quality control factors. Such a kinetic partitioning mechanism for the chaperone-substrate interaction may be essential for the quality control of the biogenesis of OMPs.

The effects on handling qualities of elastic modes interaction with the rigid body dynamics of a large flexible aircraft are studied by a mathematical computer simulation. An analytical method to predict the pilot ratings when there is a severe modes interactions is developed. This is done by extending the optimal control model of the human pilot response to include the mode decomposition mechanism into the model. The handling qualities are determined for a longitudinal tracking task using a large flexible aircraft with parametric variations in the undamped natural frequencies of the two lowest frequency, symmetric elastic modes made to induce varying amounts of mode interaction.

Constraint on the second functional derivative of the exchange-correlation energy

NASA Astrophysics Data System (ADS)

Joubert, D. P.

2012-09-01

Using the density functional adiabatic connection approach for an N-electron system it is shown that ? γ is the coupling constant that scales the electron-electron interaction strength. For the non-interacting Kohn-Sham Hamiltonian γ = 0 and for the fully interacting system γ = 1. ? is the Hartree plus exchange-correlation energy while f 0(r) and fγ(r) are the Fukui functions of the non-interacting and interacting systems, respectively. This identity can serve to test the internal self-consistency or quality of approximate functionals. The quality of some popular approximate exchange and correlation functionals are tested for a simple model system.

A conceptual account to the quality of the user experience that interactive storytelling intends to facilitate is introduced. Building on socialscientific research from 'old' entertainment media, the experiential qualities of curiosity, suspense, aesthetic pleasantness, self-enhancement, and optimal task engagement ("flow") are proposed as key elements of a theory of user experience in interactive storytelling. Perspectives for the evolution of the model, research and application are briefly discussed.

2013-08-01

This study examined the direct and indirect effects between training in the Responsive Classroom® (RC) approach, teachers' uptake of RC practices, and teacher-student interaction quality, using a structural equation modeling framework. A total of 24 schools were randomly assigned to experimental or control conditions. Third- and fourth-grade teachers in treatment schools (n=132) received training in the RC approach, whereas teachers in control schools (n=107) continued "business as usual." Observers rated teachers' fidelity of implementation (FOI) of RC practices 5 times throughout the year using the Classroom Practices Observation Measure. In addition, teachers completed self-report measures of FOI, the Classroom Practices Teacher Survey and Classroom Practices Frequency Survey, at the end of the school year. Teacher-student interactions were rated during classroom observations using the Classroom Assessment Scoring System. Controlling for teachers' grade level and teacher-student interaction quality at pretest, RC training was expected to predict posttest teacher-student interaction quality directly and indirectly through FOI. Results supported only a significant indirect effect, β=0.85, p=.002. Specifically, RC teachers had higher levels of FOI of RC practices, β=1.62, p<.001, R2=.69. In turn, FOI related to greater improvement in teacher-student interaction quality, β=0.52, p=.001, R2=.32. Discussion highlights factors contributing to variability in FOI and school administrators roles in supporting FOI. Copyright © 2013 Society for the Study of School Psychology.

Mangunsong, N. I.

2018-01-01

The existence of social interactions park in Jakarta is an oasis in the middle of a concrete jungle. Parks is a response to the need for open space as a place of recreation and community interaction. Often the social interaction parks built by the government does not function as expected, but other functions such as a place to sell, trash, unsafe so be rarely visited by visitors. The purpose of this study was to analyze the factors that affect the quality of social interaction parks in Jakarta by conducting descriptive analysis and correlation analysis of the variables assessment. The results of the analysis can give an idea of social interactions park based on community needs and propose the development of social interactioncity park. The object of study are 25 social interaction parks in 5 municipalities of Jakarta. The method used is descriptive analysis method, correlation analysis using SPSS 19 and using crosstab, chi-square tests. The variables are 5 aspects of Design, Plants composition: Selection type of plant (D); the beauty and harmony (Ind); Maintenance and fertility (P); Cleanliness and Environmental Health (BS); Specificity (Drainage, Multi Function garden, Means, Concern/Mutual cooperation, in dense settlements) (K). The results of analysis show that beauty is the most significant correlation with the value of the park followed by specificity, cleanliness and maintenance. Design was not the most significant variable affecting the quality of the park. The results of this study can be used by the Department of Parks and Cemeteries as input in managing park existing or to be developed and to improve the quality of social interaction park in Jakarta.

Exploring the additive effects of stimulus quality and word frequency: the influence of local and list-wide prime relatedness.

PubMed

Scaltritti, Michele; Balota, David A; Peressotti, Francesca

2013-01-01

Stimulus quality and word frequency produce additive effects in lexical decision performance, whereas the semantic priming effect interacts with both stimulus quality and word frequency effects. This pattern places important constraints on models of visual word recognition. In Experiment 1, all three variables were investigated within a single speeded pronunciation study. The results indicated that the joint effects of stimulus quality and word frequency were dependent upon prime relatedness. In particular, an additive effect of stimulus quality and word frequency was found after related primes, and an interactive effect was found after unrelated primes. It was hypothesized that this pattern reflects an adaptive reliance on related prime information within the experimental context. In Experiment 2, related primes were eliminated from the list, and the interactive effects of stimulus quality and word frequency found following unrelated primes in Experiment 1 reverted to additive effects for the same unrelated prime conditions. The results are supportive of a flexible lexical processor that adapts to both local prime information and global list-wide context.

Children's interactions with peers in early childhood have been consistently linked to their academic and social outcomes. Although both child and classroom characteristics have been implicated as contributors to children's success, there has been scant research linking child temperament, teacher-child relationship quality, and peer interactions in the same study. The purpose of this study is to examine children's early temperament, rated at preschool age, as a predictor of interactions with peers (i.e., aggression, relational aggression, victimization, and prosociality) in third grade while considering teacher-child relationship quality in kindergarten through second grades as a moderator and mediator of this association. The sample (N=1364) was drawn from the NICHD Study of Early Child Care and Youth Development. Results from structural equation models indicated that teacher-child conflict in early elementary grades mediated links between children's temperament and later peer interactions. Findings underscore the importance of considering children's temperament traits and teacher-child relationship quality when examining the mechanisms of the development of peer interactions. © 2013.

Anthropogenic shift of planktonic food web structure in a coastal lagoon by freshwater flow regulation

2017-03-01

Anthropogenic modification of aquatic systems has diverse impacts on food web interactions and ecosystem states. To reverse the adverse effects of modified freshwater flow, adequate management of discharge is required, especially due to higher water requirements and abstractions for human use. Here, we look at the effects of anthropogenically controlled freshwater flow regimes on the planktonic food web of a Ramsar listed coastal lagoon that is under recovery from degradation. Our results show shifts in water quality and plankton community interactions associated to changes in water flow. These shifts in food web interactions represent modifications in habitat complexity and water quality. At high flow, phytoplankton-zooplankton interactions dominate the food web. Conversely, at low flow, bacteria, viruses and nano/picoplankton interactions are more dominant, with a substantial switch of the food web towards heterotrophy. This switch can be associated with excess organic matter loading, decomposition of dead organisms, and synergistic and antagonistic interactions. We suggest that a lower variability in flow amplitude could be beneficial for the long-term sustaining of water quality and food web interactions, while improving the ecosystem health of systems facing similar stresses as the Coorong.

People that watch today's 3D visual programs, such as 3D cinema, 3D TV and 3D games, experience wide and dynamically varying ranges of 3D visual immersion and 3D quality of experience (QoE). It is necessary to be able to deploy reliable methodologies that measure each viewers subjective experience. We propose a new methodology that we call Multimodal Interactive Continuous Scoring of Quality (MICSQ). MICSQ is composed of a device interaction process between the 3D display and a separate device (PC, tablet, etc.) used as an assessment tool, and a human interaction process between the subject(s) and the device. The scoring process is multimodal, using aural and tactile cues to help engage and focus the subject(s) on their tasks. Moreover, the wireless device interaction process makes it possible for multiple subjects to assess 3D QoE simultaneously in a large space such as a movie theater, and at di®erent visual angles and distances.

The cultivated bread wheat (Triticum aestivum L.) possesses unique flour quality, which can be processed into many end-use food products such as bread, pasta, chapatti (unleavened flat bread), biscuit, etc. The present wheat varieties require improvement in processing quality to meet the increasing demand of better quality food products. However, processing quality is very complex and controlled by many genes, which have not been completely explored. To identify the candidate genes whose expressions changed due to variation in processing quality and interaction (quality x development), genome-wide transcriptome studies were performed in two sets of diverse Indian wheat varieties differing for chapatti quality. It is also important to understand the temporal and spatial distributions of their expressions for designing tissue and growth specific functional genomics experiments. Gene-specific two-way ANOVA analysis of expression of about 55 K transcripts in two diverse sets of Indian wheat varieties for chapatti quality at three seed developmental stages identified 236 differentially expressed probe sets (10-fold). Out of 236, 110 probe sets were identified for chapatti quality. Many processing quality related key genes such as glutenin and gliadins, puroindolines, grain softness protein, alpha and beta amylases, proteases, were identified, and many other candidate genes related to cellular and molecular functions were also identified. The ANOVA analysis revealed that the expression of 56 of 110 probe sets was involved in interaction (quality x development). Majority of the probe sets showed differential expression at early stage of seed development i.e. temporal expression. Meta-analysis revealed that the majority of the genes expressed in one or a few growth stages indicating spatial distribution of their expressions. The differential expressions of a few candidate genes such as pre-alpha/beta-gliadin and gamma gliadin were validated by RT-PCR. Therefore, this study identified several quality related key genes including many other genes, their interactions (quality x development) and temporal and spatial distributions. The candidate genes identified for processing quality and information on temporal and spatial distributions of their expressions would be useful for designing wheat improvement programs for processing quality either by changing their expression or development of single nucleotide polymorphisms (SNPs) markers.

Genome-wide transcriptome study in wheat identified candidate genes related to processing quality, majority of them showing interaction (quality x development) and having temporal and spatial distributions

Background The cultivated bread wheat (Triticum aestivum L.) possesses unique flour quality, which can be processed into many end-use food products such as bread, pasta, chapatti (unleavened flat bread), biscuit, etc. The present wheat varieties require improvement in processing quality to meet the increasing demand of better quality food products. However, processing quality is very complex and controlled by many genes, which have not been completely explored. To identify the candidate genes whose expressions changed due to variation in processing quality and interaction (quality x development), genome-wide transcriptome studies were performed in two sets of diverse Indian wheat varieties differing for chapatti quality. It is also important to understand the temporal and spatial distributions of their expressions for designing tissue and growth specific functional genomics experiments. Results Gene-specific two-way ANOVA analysis of expression of about 55 K transcripts in two diverse sets of Indian wheat varieties for chapatti quality at three seed developmental stages identified 236 differentially expressed probe sets (10-fold). Out of 236, 110 probe sets were identified for chapatti quality. Many processing quality related key genes such as glutenin and gliadins, puroindolines, grain softness protein, alpha and beta amylases, proteases, were identified, and many other candidate genes related to cellular and molecular functions were also identified. The ANOVA analysis revealed that the expression of 56 of 110 probe sets was involved in interaction (quality x development). Majority of the probe sets showed differential expression at early stage of seed development i.e. temporal expression. Meta-analysis revealed that the majority of the genes expressed in one or a few growth stages indicating spatial distribution of their expressions. The differential expressions of a few candidate genes such as pre-alpha/beta-gliadin and gamma gliadin were validated by RT-PCR. Therefore, this study identified several quality related key genes including many other genes, their interactions (quality x development) and temporal and spatial distributions.

Garneau, Chelsea L; Higginbotham, Brian; Adler-Baeder, Francesca

2015-12-01

Using an Actor-Partner Interdependence Model, we examined remarriage beliefs as predictors of marital quality and positive interaction in a sample of 179 stepcouples. Three beliefs were measured using subscales from the Remarriage Belief Inventory (RMBI) including success is slim, children are the priority, and finances should be pooled. Several significant actor and partner effects were found for both wives' and husbands' beliefs. Wives' marital quality was positively associated with their own beliefs that finances should be pooled and negatively associated with their own beliefs that success is slim. Wives' reports of their own and spouses' positive interaction were both positively associated with their beliefs that finances should be pooled. Their reports of spouses' positive interaction were also negatively associated with husbands' beliefs that success is slim. Husbands' marital quality was positively associated with wives' beliefs that children are the priority, positively associated with their own beliefs that finances should be pooled, and negatively with success is slim. Positive interaction for husbands was positively associated with wives' beliefs that finances should be pooled and negatively associated with their own beliefs that success is slim. Finally, husbands' reports of positive interaction for their spouses were positively associated with wives' beliefs that finances should be pooled. Implications for future research utilizing dyadic data analysis with stepcouples are addressed. © 2015 Family Process Institute.

Additive interaction between heterogeneous environmental ...

BACKGROUND Environmental exposures often occur in tandem; however, epidemiological research often focuses on singular exposures. Statistical interactions among broad, well-characterized environmental domains have not yet been evaluated in association with health. We address this gap by conducting a county-level cross-sectional analysis of interactions between Environmental Quality Index (EQI) domain indices on preterm birth in the Unites States from 2000-2005.METHODS: The EQI, a county-level index constructed for the 2000-2005 time period, was constructed from five domain-specific indices (air, water, land, built and sociodemographic) using principal component analyses. County-level preterm birth rates (n=3141) were estimated using live births from the National Center for Health Statistics. Linear regression was used to estimate prevalence differences (PD) and 95% confidence intervals (CI) comparing worse environmental quality to the better quality for each model for a) each individual domain main effect b) the interaction contrast and c) the two main effects plus interaction effect (i.e. the “net effect”) to show departure from additive interaction for the all U.S counties. Analyses were also performed for subgroupings by four urban/rural strata. RESULTS: We found the suggestion of antagonistic interactions but no synergism, along with several purely additive (i.e., no interaction) associations. In the non-stratified model, we observed antagonistic interac

Background Quality of the parent-child relationship is a robust predictor of behavioral and emotional health for children and adolescents; the application to physical health is less clear. Methods We investigated the links between observed parent-child relationship quality in an interaction task and antibody response to meningococcal conjugate vaccine in a longitudinal study of 164 ambulatory 10-11 year-old children; additional analyses examine associations with cortisol reactivity, BMI, and somatic illness. Results Observed negative/conflict behavior in the interaction task predicted a less robust antibody response to meningococcal serotype C vaccine in the child over a 6 month-period, after controlling for socio-economic and other covariates. Observer rated interaction conflict also predicted increased cortisol reactivity following the interaction task and higher BMI, but these factors did not account for the link between relationship quality and antibody response. Conclusions The results begin to document the degree to which a major source of child stress exposure, parent-child relationship conflict, is associated with altered immune system development in children, and may constitute an important public health consideration.

Beyond image quality: designing engaging interactions with digital products

de Ridder, Huib; Rozendaal, Marco C.

2008-02-01

Ubiquitous computing (or Ambient Intelligence) promises a world in which information is available anytime anywhere and with which humans can interact in a natural, multimodal way. In such world, perceptual image quality remains an important criterion since most information will be displayed visually, but other criteria such as enjoyment, fun, engagement and hedonic quality are emerging. This paper deals with engagement, the intrinsically enjoyable readiness to put more effort into exploring and/or using a product than strictly required, thus attracting and keeping user's attention for a longer period of time. The impact of the experienced richness of an interface, both visually and degree of possible manipulations, was investigated in a series of experiments employing game-like user interfaces. This resulted in the extension of an existing conceptual framework relating engagement to richness by means of two intermediating variables, namely experienced challenge and sense of control. Predictions from this revised framework are evaluated against results of an earlier experiment assessing the ergonomic and hedonic qualities of interactive media. Test material consisted of interactive CD-ROM's containing presentations of three companies for future customers.

We address this gap by conducting a county-level cross-sectional analysis of interactions between Environmental Quality Index (EQI) domain indices on preterm birth in the Unites States from 2000 to 2005. The EQI, a county-level index constructed for the 2000-2005 time period, was constructed from five domain-specific indices (air, water, land, built, and sociodemographic) using principal component analyses.

Analyses were also performed for subgroupings by four urban/rural strata. We found the suggestion of antagonistic interactions but no synergism, along with several purely additive (i.e., no interaction) associations. In the non-stratified model, we observed antagonistic interactions, between the sociodemographic/air domains [net effect (i.e., the association, including main effects and interaction effects) PD: -0.004 (95% CI: -0.007, 0.000), interaction contrast: -0.013 (95% CI: -0.020, -0.007)] and built/air domains [net effect PD: 0.008 (95% CI 0.004, 0.011), interaction contrast: -0.008 (95% CI: -0.015, -0.002)]. Most interactions were between the air domain and other respective domains. Interactions differed by urbanicity, with more interactions observed in non-metropolitan regions. Observed antagonistic associations may indicate that those living in areas with multiple detrimental domains may have other interfering factors reducing the burden of environmental exposure. This study is the first to explore interactions across different environmental domains and demonstrates the utility of the EQI to examine the relationship between environmental domain interactions and human health. While we did observe some departures from additivity, many observed effects were additive. This study demonstrated that interactions between environmental domains should be considered in future analyses.

This study investigated different environmental and contextual factors associated with maltreated children's adjustment in foster care. Participants included 83 children (52 boys), ages 1-7 years, and their foster caregivers. Quality of interaction with the foster caregiver was assessed from direct observation of a free-play situation; foster caregiver attachment state of mind and commitment toward the child were assessed using two interviews; disruptive behavior symptoms were reported by foster caregivers. Results showed that quality of interaction between foster caregivers and children were associated with behavior problems, such that higher-quality interactions were related to fewer externalizing and internalizing problems. Foster caregivers' state of mind and commitment were interrelated but not directly associated with behavior problems of foster children. Type of placement moderated the association between foster caregiver commitment and foster child behavior problems. Whereas greater foster caregiver commitment was associated with higher levels of adjustment for children in foster families (kin and non-kin), this was not the case in foster-to-adopt families. Finally, the associations between foster child behavior problems and history of maltreatment and placement related-risk conditions fell below significance after considering child age and quality of interaction with the foster caregiver. Findings underscore the crucial contribution of the foster caregiver-child relationship to fostering child adjustment and, thereby, have important implications for clinical services offered to this population.

The interactive effects of housing and neighbourhood quality on psychological well-being.

Jones-Rounds, McKenzie L; Evans, Gary W; Braubach, Matthias

2014-02-01

Many individuals are subject to the physically and mentally detrimental effects of living in substandard housing and inadequate neighbourhoods. We propose that better physical neighbourhood quality can partially offset some of the negative effects of poor housing quality on psychological well-being. Interviews and questionnaires were used to collect data in a cross-sectional study of housing quality, the state of the surrounding environment, and individual health and well-being for 5605 European adults from the Large Analysis and Review of European housing and health Status conducted by WHO in eight European cities. Multilevel random coefficient modelling was used to statistically analyse the main and interactive effects of housing quality and neighbourhood quality on psychological well-being. Socioeconomic status, employment status, gender and marital status were included as statistical controls. Substandard housing quality and poor neighbourhood quality each contribute to lower psychological well-being. Furthermore better neighbourhood quality buffers against the negative effects of poor housing quality on psychological well-being. These results fill a gap in research concerning the ability of neighbourhood quality to amplify or attenuate housing quality impacts on well-being.

Interaction between 5-HTTLPR genotype and cognitive stress vulnerability on sleep quality: effects of sub-chronic tryptophan administration.

PubMed

van Dalfsen, Jens H; Markus, C Rob

2015-02-02

Abundant evidence suggests that allelic variation in the serotonin transporter-linked polymorphic region (5-HTTLPR) influences susceptibility to stress and its affective consequences due to brain serotonergic vulnerability. Based on recent assumptions, the present study examined whether the 5-HTTLPR genotype may also interact with a vulnerability to chronic stress experience (conceptualized by trait neuroticism) in order to influence sleep quality and, additionally, whether this is influenced by brain serotonergic manipulations. In a well-balanced experimental design, homozygous S-allele (n = 57) and L-allele (n = 54) genotypes with high and low chronic stress vulnerability (neuroticism) were first assessed for general past sleep quality during a month before onset of the experiment. Then subjects were assessed for sleep quality following 7 days of tryptophan (3.0g/day) or placebo intake. Although high neuroticism was significantly related to a higher frequency of stressful life events and daily hassles, it did not interact with the 5-HTTLPR genotype on general past sleep quality. However, as expected, a 7 day period of tryptophan administration was exclusively associated with better sleep quality scores in the S'/S' genotype with high trait neuroticism. Current findings suggest that 5-HTTLPR does not directly interact with stress vulnerability in order to influence sleep quality. Instead, based on current and previous findings, it is suggested that the S'/S' 5-HTTLPR genotype promotes the risk for stress-related sleep disturbances because of an increased susceptibility to the depressogenic consequences of stress. Accordingly, by way of reducing depressive symptomatology, tryptophan augmentation may particularly improve sleep quality in stress-vulnerable individuals carrying the 5-HTTLPR S-allele. © The Author 2015.

To identify elements of the physiotherapist-patient interaction considered by patients when they evaluate the quality of care in outpatient rehabilitation settings. A qualitative study with nine focus groups, Two researchers conducted the focus groups, and a topic guide with predetermined questions was used. Each group discussion was audiotaped,, transcribed verbatim and analyzed thematically according to a modified grounded theory approach. Three postacute ambulatory centers in Barcelona, Madrid and Seville (Spain). Fifty-seven adults undergoing outpatient rehabilitation for musculoskeletal conditions/injuries. Patients based their evaluations of quality of care on their assessment of physiotherapists' willingness to provide information and education, technical expertise and interpersonal manners (eg. respect, emotional support and sensitivity changes in the patient's status). Both positive and negative aspects of the physiotherapist-patient interaction emerged under all these themes, except for friendly and respectful communication. This study identified which elements of the physiotherapist-patient interaction are considered by patients when evaluating the quality of care in rehabilitation outpatient settings. Further research should work to develop self-report questionnaires about patients' experiences of the physiotherapist-patient interaction in rehabilitation services to provide empirical and quantitative evidence.

Background China has a large population with cardiovascular disease (CVD) that requires extensive self-management. Mobile health (mHealth) apps may be a useful tool for CVD self-management. Little is currently known about the types and quality of health information provided in Chinese CVD mobile apps and whether app functions are conducive to promoting CVD self-management. Objective We undertook a systematic review to evaluate the types and quality of health information provided in Chinese CVD mobile apps and interactive app functions for promoting CVD self-management. Methods Mobile apps targeting end users in China with CVD conditions were selected in February 2017 through a multi-stage process. Three frameworks were used to evaluate the selected apps: (1) types of health information offered were assessed using our Health Information Wants framework, which encompasses 7 types of information; (2) quality of information provided in the apps was assessed using the 11 guidelines recommended by the National Library of Medicine of the National Institutes of Health; and (3) types of interactive app functions for CVD self-management were assessed using a 15-item framework adapted from the literature, including our own prior work. Results Of 578 apps identified, 82 were eligible for final review. Among these, information about self-care (67/82, 82%) and information specifically regarding CVD (63/82, 77%) were the most common types of information provided, while information about health care providers (22/82, 27%) and laboratory tests (5/82, 6%) were least common. The most common indicators of information quality were the revealing of apps’ providers (82/82, 100%) and purpose (82/82, 100%), while the least common quality indicators were the revealing of how apps’ information was selected (1/82, 1%) and app sponsorship (0/82, 0%). The most common interactive functions for CVD self-management were those that enabled user interaction with the app provider (57/82, 70%) and with health care providers (36/82, 44%), while the least common interactive functions were those that enabled lifestyle management (13/82, 16%) and psychological health management (6/82, 7%). None of the apps covered all 7 types of health information, all 11 indicators of information quality, or all 15 interactive functions for CVD self-management. Conclusions Chinese CVD apps are insufficient in providing comprehensive health information, high-quality information, and interactive functions to facilitate CVD self-management. End users should exercise caution when using existing apps. Health care professionals and app developers should collaborate to better understand end users’ preferences and follow evidence-based guidelines to develop mHealth apps conducive to CVD self-management.

Predator-Prey Interactions are Context Dependent in a Grassland Plant-Grasshopper-Wolf Spider Food Chain.

PubMed

Laws, Angela N; Joern, Anthony

2015-06-01

Species interactions are often context dependent, where outcomes vary in response to one or more environmental factors. It remains unclear how abiotic conditions like temperature combine with biotic factors such as consumer density or food quality to affect resource availability or influence species interactions. Using the large grasshopper Melanoplus bivittatus (Say) and a common wolf spider [Rabidosa rabida (Walkenaer)], we conducted manipulative field experiments in tallgrass prairie to examine how spider-grasshopper interactions respond to manipulations of temperature, grasshopper density, and food quality. Grasshopper survival was density dependent, as were the effects of spider presence and food quality in context-dependent ways. In high grasshopper density treatments, predation resulted in increased grasshopper survival, likely as a result of reduced intraspecific competition in the presence of spiders. Spiders had no effect on grasshopper survival when grasshoppers were stocked at low densities. Effects of the experimental treatments were often interdependent so that effects were only observed when examined together with other treatments. The occurrence of trophic cascades was context dependent, where the effects of food quality and spider presence varied with temperature under high-density treatments. Temperature weakly affected the impact of spider presence on M. bivittatus survivorship when all treatments were considered simultaneously, but different context-dependent responses to spider presence and food quality were observed among the three temperature treatments under high-density conditions. Our results indicate that context-dependent species interactions are common and highlight the importance of understanding how key biotic and abiotic factors combine to influence species interactions. © The Authors 2015.

Though park presence and access disparities are well studied for their associations with physical activity (PA), disparities in the availability and quality of amenities and facilities within parks have been infrequently examined. Five hundred forty-three parks from 472 block groups in the Seattle, WA and Baltimore, MD regions were audited using the Environmental Assessment of Public Recreation Spaces (EAPRS) to assess presence and quality (e.g., condition, cleanliness) of amenities (e.g., restrooms, seating) and facilities (e.g., fields, courts). General linear model regressions investigated Census 2000-derived neighborhood race/ethnicity and income main effect and interactive relationships with 7 park quality summary scores: 1) trails, 2) open space, 3) sports facilities, 4) PA facilities count, 5) PA facilities quality, 6) aesthetics, and 7) overall amenities, controlling for park size. The regions were analyzed separately due to differing race/ethnicity distributions. In the Seattle region, neighborhood income was significantly negatively associated with sports quality score (p < .043), PA facilities total count (p < .015) and the overall amenities quality score (p < .004) (unexpected direction). In the Baltimore region, neighborhood race/ethnicity (percent White/non-Hispanic) was significantly positively related to the open spaces quality score (p < .011) (expected direction). A significant income-by-race/ethnicity interaction was found for PA facilities quality (p = .014), with high-percent minority neighborhoods having higher quality parks in high- vs. low-income neighborhoods, yet was opposite in mostly White/non-Hispanic neighborhoods. The other income-by-race/ethnicity interaction was for overall amenities quality score (p = .043), where scores in high-percent minority neighborhoods were best in high- vs. low-income neighborhoods. There was little difference in scores within mostly White or mixed neighborhoods by income. Patterns of association of neighborhood race/ethnicity and income with park qualities differed between regions. In the Seattle region, "equitable differences" were found, where lower income neighborhoods had better park quality on average. In the Baltimore region, park quality was more consistently negatively associated with income and race/ethnic diversity, and complex interactions of race/ethnicity by income were detected. These findings emphasize the need to explore other factors that may explain variations in park quality, like local policy, citizen involvement in park decision-making, park funding and allocation, sources of funding and park priorities.

Urinary incontinence (UI) is a prevalent health issue that has significant detrimental effects on quality of life. The Internet offers a unique vehicle for incontinent women to access information that could facilitate conservative self-help therapy. An evaluation of Canadian websites offering female UI information was conducted to determine their quality and readability. We evaluated websites using published general quality criteria for health sites and a quality assessment tool compiled by the authors for specific UI information derived from published, peer-reviewed clinical practice guidelines. Three health care professionals reviewed sites for quality, Canadian content, and interactivity. The readability of health information was also evaluated. Fifty-six Canadian sites (18 professional, 22 organizational, 16 commercial) were evaluated. Significant agreement was found among the raters' evaluations on all measures. For all sites, the mean scores were general quality, 9/14; specific UI quality, 30/122; reading ease, 37/100; grade level, 10.9. The median score for Canadian content was high, but for interactivity it was low. The only significant difference between site types was for general quality (F [2,165]=3.38, P=0.036). Post hoc Tukey's tests showed a significant difference between organizational and commercial sites, with organizational sites having higher general quality. Canadian websites providing female UI information have moderately high general quality, low specific UI information quality, minimal interactivity, and more than minimal Canadian content. The reading level of most sites is too high for average consumers. A webliography of the best sites has been developed to guide patients.

Children's aesthetic understanding of photographic art and the quality of art-related parent-child interactions.

PubMed

Szechter, Lisa E; Liben, Lynn S

2007-01-01

This research was designed to examine the quality of children's aesthetic understanding of photographs, observe social interactions between parents and children in this aesthetic domain, and study whether qualitatively different dyadic interactions were associated with children's own aesthetic understanding. Parents and children (7-13 years; 40 dyads) individually completed measures of aesthetic understanding and jointly selected photographs for a souvenir scrapbook. Parents' artistic experience varied widely and was associated with their own performance on aesthetic understanding measures. Children's performance on the individual aesthetic tasks was related to age, but not to parents' art experience nor to the qualities of parent-child discussions of aesthetic concepts. Among both parents and children, artistic experience was associated with aesthetic preferences for photographs.

Ergonomics and quality management--humans in interaction with technology, work environment, and organization.

PubMed

Eklund, J A

1999-01-01

In many studies, ergonomics has been shown to influence human performance. The aim of this paper was to demonstrate important ergonomics influences on quality in industrial production, from the perspective of interactions between humans, technology, organization, and work environment. A second aim was to elaborate on the implications of these findings for the development of quality management strategies. This paper shows that ergonomics problems in terms of adverse work environmental conditions, inappropriate design of technology, and an unsuitable organization are important causes of quality deficiencies. Problem solving aimed at improving ergonomics, quality, and productivity simultaneously is likely to obtain support from most of the interest parties of the company, and may also enhance participation. Ergonomics has the potential of becoming a driving force for the development of new quality management strategies.

2014-01-01

There is compelling evidence that the quality of maternal and paternal parenting behavior bears critical importance for child development. Yet, less is known of the degree of similarity between maternal and paternal parenting behavior in families, and especially little is known about the factors that may explain variation in degrees of similarity. This article aims to examine (a) the concordance (similarity) between the quality of mothers' and fathers' interactive behavior with their child and (b) the sociodemographic determinants of this concordance. The sample included 74 families (mother, father, and their child). The quality of maternal and paternal interactive behavior was assessed independently, and rated with the Maternal Behavior Q-Sort (mother-infant, 12 months; D. R. Pederson et al., 1990) or the Mutually Responsive Orientation scale (father-toddler, 18 months; N. Aksan et al., 2006). The results indicated that the overall correlation between the quality of mothers' and fathers' behavior was moderate. The concordance was greater among higher socioeconomic status families or when interacting with a boy, but did not differ according to the presence or absence of siblings in the family.

Staying Connected: Computer-Mediated and Face-to-Face Communication in College Students' Dating Relationships.

Boyle, Andrea M; O'Sullivan, Lucia F

2016-05-01

Little is known about the features, depth, and quality of communication in heterosexual dating relationships that include computer-mediated communication (CMC). This study examined these features as well as CMC's potential to facilitate self-disclosure and information-seeking. It also evaluated whether partner CMC interactions play a role in partner intimacy and communication quality. Young adults (N = 359; 18-24) attending postsecondary education institutions completed an online survey about their CMC use. To be included in the study, all participants were in established dating relationships at the time of the study and reported daily communication with their partner. CMC was linked to partners' disclosure of nonintimate information. This personal self-disclosure was linked positively to relationship intimacy and communication quality, beyond contributions from face-to-face interactions. Breadth (not depth) of self-disclosure and positively valenced interactions, in particular, proved key to understanding greater levels of intimacy in dating relationships and better communication quality as a function of CMC. CMC provides opportunities for partners to stay connected and to improve the overall quality of their intimacy and communication.

2014-11-01

Preterm birth may represent a traumatic situation for both parents and a stressful situation for the infant, potentially leading to difficulties in mother-infant relationships. This study aimed to investigate the impact of an early intervention on maternal posttraumatic stress symptoms, and on the quality of mother-infant interactions, in a sample of very preterm infants and their mothers. Half of the very preterm infants involved in the study (n=26) were randomly assigned to a 3-step early intervention program (at 33 and 42 weeks after conception and at 4 months' corrected age). Both groups of preterm infants (with and without intervention) were compared to a group of full-term infants. The impact of the intervention on maternal posttraumatic stress symptoms was assessed 42 weeks after conception and when the infants were 4 and 12 months of age. The impact of the intervention on the quality of mother-infant interactions was assessed when the infants were 4 months old. Results showed a lowering of mothers' posttraumatic stress symptoms between 42 weeks and 12 months in the group of preterm infants who received the intervention. Moreover, an enhancement in maternal sensitivity and infant cooperation during interactions was found at 4 months in the group with intervention. In the case of a preterm birth, an early intervention aimed at enhancing the quality of the mother-infant relationship can help to alleviate maternal post-traumatic stress symptoms and may have a positive impact on the quality of mother-infant interactions.

2006-06-01

Genetic exchange among chromosomal races of the common shrew Sorex araneus and the problem of reproductive barriers have been extensively studied by means of such molecular markers as mtDNA, microsatellites, and allozymes. In the present study, the interpopulation and interracial polymorphism in the common shrew was derived, using fingerprints generated by amplified DNA regions flanked by short interspersed repeats (SINEs)-interSINE PCR (IS-PCR). We used primers, complementary to consensus sequences of two short retroposons: mammalian element MIR and the SOR element from the genome of Sorex araneus. Genetic differentiation among eleven populations of the common shrew from eight chromosome races was estimated. The NP and MJ analyses, as well as multidimensional scaling showed that all samples examined grouped into two main clusters, corresponding to European Russia and Siberia. The bootstrap support of the European Russia cluster in the NJ and MP analyses was respectively 76 and 61%. The bootstrap index for the Siberian cluster was 100% in both analyses; the Tomsk race, included into this cluster, was separated with the bootstrap support of NJ/MP 92/95%.

"The Civil Rights Movement of the 1990s?": The anti-abortion movement and the struggle for racial justice.

PubMed

Hughes, Richard L

2006-01-01

In 1964, Claude and Jeanne Nolen, who were white, joined an interracial NAACP team intent on desegregating local restaurants in Austin, Texas as a test of the recently passed Civil Rights ACt. Twenty-five years later, the Nolens pleaded "no contest" in a courtroom for their continued social activism. This time the issue was not racial segregation, but rather criminal trespassing for blockading abortion clinics with Operation Rescue. The Nolens served prison sentences for direct action protests that they believe stemmed from the same commitment to Christianity and social justice as the civil rights movements. Despite its relationship to political and cultural conservatism, the anti-abortion movement since Roe v. Wade (1973) was also a product of the progressive social movements of the turbulent sixties. Utilizing oral history interviews and organizational literature, the article explores the historical context of the anti-abortion movement, specifically how the lengthy struggle for racial justice shaped the rhetoric, tactics, and ideology of the anti-abortion activists. Even after political conservatives dominated the movement in the 1980s, the successes and failures of the sixties provided a cultural lens through which grassroots anti-abortion activists forged what was arguably the largest movement of civil disobedience in American history.

A new chromosome race of Calycadenia pauciflora (Asteraceae: Heliantheae-Madiinae) from Butte County, California.

PubMed

Carr, G D; Carr, R L

2000-10-01

We initiated a biosystematic study of a recently discovered population of Calycadenia pauciflora in order to evaluate its cytogenetic relationship to previously characterized chromosome races of that species. Cytogenetic analyses of six or more artificially produced individuals of each of the five possible interracial hybrid combinations indicated that the new race (designated Wurlitzer) is differentiated from the other races (Elegans, Healdsburg, Pauciflora, Ramulosa, and Tehama) by the equivalent of 2-4 reciprocal chromosome translocations and in one instance apparently a pericentric inversion. Mean pollen stainability in the hybrids ranged from 13 to 26%. The floral and vegetative features of the new race are very similar to those of races Pauciflora, Ramulosa, and Tehama of C. pauciflora. We ascribe the apparent lack of single-step cytogenetic events in the evolution of the races of C. pauciflora to one or more of the following: (1) (in some cases) the occurrence of saltational chromosome reorganization; (2) extinction of or failure to detect intermediate populations in C. pauciflora; and (3) an insufficient consideration of the possibility of the existence of intermediate races in the closely related species, C. fremontii. We conclude that the C. fremontii-C. pauciflora alliance is one of the most complex and potentially instructive examples of diploid chromosome evolution in plants.

2017-09-01

Research is clear that power differentials between women and men shape women's human immunodeficiency virus (HIV) risks; however, little research has attempted to examine power differentials within same-sex male (SSM) couples and whether these influence sexual risk outcomes. To produce the first quantitative scale that measures power in SSM relationships, the current work was a Phase 1 qualitative study that sought to understand domains of relationship power and how power operated in the relationship among 48 Black, White, and interracial (Black-White) SSM couples recruited from San Francisco and New York. Interview domains were focused on definitions of power and perceptions of how power operated in the relationship. Findings revealed that couples described power in three key ways: as power exerted over a partner through decision-making dominance and relationship control; as power to accomplish goals through personal agency; and as couple-level power. In addition, men described ways that decision-making dominance and relationship control could be enacted in the relationship-through structural resources, emotional and sexual influence, and gender norm expectations. We discuss the implications of these findings for sexual risks and HIV care and treatment with SSM couples that are focused on closing gaps in power.

The implicit power motive in intergroup dialogues about the history of slavery.

This research demonstrates that individual differences in the implicit power motive (i.e., the concern with impact, influence, and control) moderate how African Americans communicate with White Americans in challenging intergroup dialogues. In a study with African American participants we find that the higher their implicit power motive, the more they use an affiliation strategy to communicate with a White American partner in a conversation context that evokes the history of slavery (Study 1). In a study with White American participants we find that, in the same conversation context, they are more engaged (i.e., open, attentive, and motivated) if they receive an affiliation message rather than a no-affiliation message from an African American partner (Study 2). In interracial dyads we find that African American participants' implicit power motives moderate how much they intend to signal warmth to a White American discussion partner, how much they display immediacy behaviors and use affiliation imagery in the discussion, and with what level of engagement White American participants respond (Study 3). High but not low implicit power African Americans thus employ a communication strategy-expressing affiliation and warmth-that can be effective for engaging White Americans with uncomfortable, race-identity-relevant topics.

A Novel Microcharacterization Technique in the Measurement of Strain and Orientation Gradient in Advanced Materials

NASA Technical Reports Server (NTRS)

Garmestai, H.; Harris, K.; Lourenco, L.

1997-01-01

Representation of morphology and evolution of the microstructure during processing and their relation to properties requires proper experimental techniques. Residual strains, lattice distortion, and texture (micro-texture) at the interface and the matrix of a layered structure or a functionally gradient material and their variation are among parameters important in materials characterization but hard to measure with present experimental techniques. Current techniques available to measure changes in interred material parameters (residual stress, micro-texture, microplasticity) produce results which are either qualitative or unreliable. This problem becomes even more complicated in the case of a temperature variation. These parameters affect many of the mechanical properties of advanced materials including stress-strain relation, ductility, creep, and fatigue. A review of some novel experimental techniques using recent advances in electron microscopy is presented here to measure internal stress, (micro)texture, interracial strength and (sub)grain formation and realignment. Two of these techniques are combined in the chamber of an Environmental Scanning Electron Microscope to measure strain and orientation gradients in advanced materials. These techniques which include Backscattered Kikuchi Diffractometry (BKD) and Microscopic Strain Field Analysis are used to characterize metallic and intermetallic matrix composites and superplastic materials. These techniques are compared with the more conventional x-ray diffraction and indentation techniques.

Facial anthropometric measurement is considered an essential concern of surgeons, orthodontists, artists and forensic scientists. The aim of this study is to investigate facial anthropometric norms of the young Iranian population. The study participants consisted of 200 healthy Iranian students (100 males, 100 females) aged 18-25 years old. Twenty-three liner and four angular measurements were investigated twice by a dentist. Independent-samples t test was used to compare indices between males and females and also between countries. A p value less than 0.05 was considered statistically significant. It was found that the mean measurements of c'-sn' of both sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were statistically greater in Iranian males than in females ( p  < 0.05). Comparing Iranian anthropometric norms with North American Whites, Malays, Turkish and African American women demonstrated that there were statistically significant differences in most anthropometric measurements between Iranians and other populations ( p  < 0.05). In Iranians, mean measurements of c'-sn' of the right and left sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were greater in men than in women. Comparing Iranian males and females with different ethnicities indicated several interracial differences, which should be taken into consideration when dealing with patients or also practitioners originated in this region.

New realities of the American family.

Ahlburg, D A; De Vita, C J

1992-08-01

The demographic, social, and economic characteristics of American families have changed dramatically over the past few decades. While the male breadwinner/female homemaker model was long traditionally typical,l contemporary families may be openly made up of single-parents, remarried couples, unmarried couples, stepfamilies, foster families, extended or multigenerational families, or 2 families within 1 household. Families are now most likely to have 3 or fewer children, a mother employed outside of the home, and a 50% chance of parental divorce before the children are grown. These trends are common not only in America, but in most industrialized nations around the world. In fact, family trends are so fluid that the US Census Bureau and workplace policy find it difficult to keep pace. This report presents and discusses social and demographic trends behind the ever-changing face of the American family. Households and types of families are further defined, as are the living arrangements of children, young adults, and the elderly. Marriage, divorce, and remarriage trends, age at marriage rates, and interracial marriage are then discussed. Next examined are declining family size, teenage parents, contraception and abortion, unwed mothers, and technological routes to parenthood. The changing roles of family members and family economic well-being are discussed in sections preceding closing comments on the outlook for the American family.

2003-09-01

Inspired by recently published NDA II: The Story of America's Second National Dental Association and sponsored jointly by the National Dental Association Foundation and the Colgate-Palmolive Company, an historical exhibit on dentistry in the African-American community was one of the celebrations for the Golden Anniversary of the American Academy of the History of Dentistry. This exhibit premiered on Sept. 27, 2002 in the National Museum of Dentistry located on the medical/dental campus of the University of Maryland in Baltimore. The Museum recently became an affiliate of the Smithsonian Institution. Contents of the exhibit were photographs, charts, artifacts, memorabilia, etc. These materials presented an overview of African-American activities in dental education, research, patient care, general practice, dental specialities, military service, and public health. Also included were inter-racial relationships, socioeconomic developments, and participation in civil rights endeavors that played a major role in changing out-dated accepted customs. The exhibit's purpose was to celebrate dentistry's ministrations as a health professional among African Americans in particular and the nation at large over the past two centuries. Respect for and progress of black dentists paralleled that of black physicians who were instrumental in including dentist and pharmacists as equal members in the National Medical Association since the latter's inception in 1895.

2009-01-01

Eukaryotic cells have evolved quality control mechanisms to degrade aberrant mRNA molecules and prevent the synthesis of defective proteins that could be deleterious for the cell. The exosome, a protein complex with ribonuclease activity, is a key player in quality control. An early quality checkpoint takes place cotranscriptionally but little is known about the molecular mechanisms by which the exosome is recruited to the transcribed genes. Here we study the core exosome subunit Rrp4 in two insect model systems, Chironomus and Drosophila. We show that a significant fraction of Rrp4 is associated with the nascent pre-mRNPs and that a specific mRNA-binding protein, Hrp59/hnRNP M, interacts in vivo with multiple exosome subunits. Depletion of Hrp59 by RNA interference reduces the levels of Rrp4 at transcription sites, which suggests that Hrp59 is needed for the exosome to stably interact with nascent pre-mRNPs. Our results lead to a revised mechanistic model for cotranscriptional quality control in which the exosome is constantly recruited to newly synthesized RNAs through direct interactions with specific hnRNP proteins.

Basic principles of drug--excipients interactions.

PubMed

Vranić, Edina

2004-05-01

Excipients are generally considered inert additives included in drug formulation to help in the manufacturing, administration or absorption. Other reasons for inclusion concern product differentiation, appearance enhancement or retention of quality. Excipients can initiate, propagate or participate in chemical or physical interactions with an active substance, possibly leading to compromised quality or performance of the medication. Understanding the chemical and physical nature of excipients, the impurities or residues associated with them and how they may interact with other materials, or with each other, forewarns the pharmaceutical technologist of possibilities for undesirable developments.

Herb–drug interactions: an overview of systematic reviews

Posadzki, Paul; Watson, Leala; Ernst, Edzard

2013-01-01

OBJECTIVES The aim of this overview of systematic reviews (SRs) is to evaluate critically the evidence regarding interactions between herbal medicinal products (HMPs) and synthetic drugs. METHODS Four electronic databases were searched to identify relevant SRs. RESULTS Forty‐six SRs of 46 different HMPs met our inclusion criteria. The vast majority of SRs were of poor methodological quality. The majority of these HMPs were not associated with severe herb–drug interactions. Serious herb–drug interactions were noted for Hypericum perforatum and Viscum album. The most severe interactions resulted in transplant rejection, delayed emergence from anaesthesia, cardiovascular collapse, renal and liver toxicity, cardiotoxicity, bradycardia, hypovolaemic shock, inflammatory reactions with organ fibrosis and death. Moderately severe interactions were noted for Ginkgo biloba, Panax ginseng, Piper methysticum, Serenoa repens and Camellia sinensis. The most commonly interacting drugs were antiplatelet agents and anticoagulants. CONCLUSION The majority of the HMPs evaluated in SRs were not associated with drug interactions with serious consequences. However, the poor quality and the scarcity of the primary data prevent firm conclusions. PMID:22670731

Identifying risk and protective factors for language development informs interventions for children with developmental language disorder (DLD). Maternal responsive and intrusive communicative behaviours are associated with language development. Mother-child interaction quality may influence how children use these behaviours in language learning. To identify (1) communicative behaviours and interaction quality associated with language outcomes; (2) whether the association between a maternal intrusive behaviour (directive) and child language scores changed alongside a maternal responsive behaviour (expansion); and (3) whether interaction quality modified these associations. Language skills were assessed at 24, 36 and 48 months in 197 community-recruited children who were slow to talk at 18 months. Mothers and 24-month-olds were video-recorded playing at home. Maternal praise, missed opportunities, and successful and unsuccessful directives (i.e., whether followed by the child) were coded during a 10-min segment. Interaction quality was rated using a seven-point fluency and connectedness (FC) scale, during a 5-min segment. Linear regressions examined associations between these behaviours/rating and language scores. Interaction analysis and simple slopes explored effect modification by FC. There was no evidence that missed opportunities or praise were associated with language scores. Higher rates of successful directives in the unadjusted model and unsuccessful directives in the adjusted model were associated with lower 24-month-old receptive language scores (e.g., unsuccessful directives effect size (ES) = -0.41). The association between unsuccessful directives and receptive language was weaker when adjusting for co-occurring expansions (ES = -0.34). Both types of directives were associated with poorer receptive and expressive language scores in adjusted models at 36 and 48 months (e.g., unsuccessful directive and 48-month receptive language, ES = -0.66). FC was positively associated with 24-, 36- and 48-month language scores in adjusted models (e.g., receptive language at 24 months, ES = 0.21, at 48 months, ES = 0.18). Interaction analysis showed the negative association between successful directives and 24-month receptive language existed primarily in poorly connected dyads with low FC levels. These findings illustrate the effects of the combined interaction between different maternal communicative behaviours and features of the interaction itself on child language development, and the need to consider both in research and practice. Whilst more intrusive directives were associated with poorer language scores, this association attenuated when adjusting for co-occurring responsive expansions, and the association was strongest for children in lower quality interactions. This work may inform clinical practice by helping clinicians target the most appropriate communicative behaviours for specific mother-child dyads. © 2017 Royal College of Speech and Language Therapists.

Interspecific relationships such as mutualism and parasitism are major drivers of biodiversity. Because such interactions often comprise more than two species, ecological studies increasingly focus on complex multispecies systems. However, the spatial heterogeneity of multi-species interactions is often poorly understood. Here, we investigate the unusual interaction of a bat (Kerivoula hardwickii hardwickii) and two pitcher plant species (Nepenthes hemsleyana and N. bicalcarata) whose pitchers serve as roost for bats. Nepenthes hemsleyana offers roosts of higher quality, indicated by a more stable microclimate compared to N. bicalcarata but occurs at lower abundance and is less common than the latter. Whereas N. hemsleyana benefits from the roosting bats by gaining nitrogen from their feces, the bats' interaction with N. bicalcarata seems to be commensal or even parasitic. Bats stayed longer in roosts of higher quality provided by N. hemsleyana and preferred them to pitchers of N. bicalcarata in a disturbance experiment. Moreover, bats roosting only in pitchers of N. hemsleyana had a higher body condition and were less infested with parasites compared to bats roosting in pitchers of N. bicalcarata. Our study shows how the local supply of roosts with different qualities affects the behavior and status of their inhabitants and-as a consequence-how the demand of the inhabitants can influence evolutionary adaptations of the roost providing species.

The study purposes were to (a) describe interaction behaviors and factors that may effect communication and (b) explore associations between interaction behaviors and nursing care quality indicators among 38 mechanically ventilated patients (age ≥60 years) and their intensive care unit nurses (n = 24). Behaviors were measured by rating videorecorded observations from the Study of Patient-Nurse Effectiveness with Communication Strategies (SPEACS). Characteristics and quality indicators were obtained from the SPEACS dataset and medical chart abstraction. All positive behaviors occurred at least once. Significant (p < 0.05) associations were observed between (a) positive nurse and positive patient behaviors, (b) patient unaided augmentative and alternative communication (AAC) strategies and positive nurse behaviors, (c) individual patient unaided AAC strategies and individual nurse positive behaviors, (d) positive nurse behaviors and pain management, and (e) positive patient behaviors and sedation level. Findings provide evidence that nurse and patient behaviors effect communication and may be associated with nursing care quality. Copyright 2014, SLACK Incorporated.

Cornelius, Talea; Birk, Jeffrey L; Edmondson, Donald; Schwartz, Joseph E

Social interaction quality is related to cardiovascular functioning. Trait emotional reactivity may amplify cardiovascular responses to social interactions, but is often examined as a tendency to react to negative events. We took a broader approach by examining the joint effects of positive and negative emotional reactivity and social interaction quality on ambulatory blood pressure (ABP) and heart rate (HR) responses to daily social interactions. Participants were part of a larger study on BP and cardiovascular health (N = 805; M Age  = 45.3; 40.1% male). Participants completed a measure of emotional reactivity (BIS/BAS) and 24-hour ABP monitoring accompanied by ecological momentary assessments (EMA) about just-experienced social interactions and their pleasantness. Multilevel models tested the associations of emotional reactivity, average pleasantness, and momentary pleasantness with BP and HR. Participants who reported more pleasant interactions on average had lower BP (systolic BP: B = -0.51 mmHg; diastolic BP: B = -0.46 mmHg). These effects did not depend on emotional reactivity. The effect of momentary pleasantness depended on BIS/BAS; in less reactive participants, greater pleasantness was associated with lower HR, B = -0.13 bpm; in more reactive participants, greater pleasantness was associated with increased HR, B = 0.16). Participants who had more pleasant social interactions throughout the day had lower mean ABP. The acute effect of a given social interaction on HR depended on emotional reactivity: HR increased for participants high in emotional reactivity during pleasant interactions. Thus, emotional reactivity may influence cardiovascular responses to social stimuli. Copyright © 2018 Elsevier Inc. All rights reserved.

Evaluating Land-Atmosphere Interactions with the North American Soil Moisture Database

NASA Astrophysics Data System (ADS)

Giles, S. M.; Quiring, S. M.; Ford, T.; Chavez, N.; Galvan, J.

2015-12-01

The North American Soil Moisture Database (NASMD) is a high-quality observational soil moisture database that was developed to study land-atmosphere interactions. It includes over 1,800 monitoring stations the United States, Canada and Mexico. Soil moisture data are collected from multiple sources, quality controlled and integrated into an online database (soilmoisture.tamu.edu). The period of record varies substantially and only a few of these stations have an observation record extending back into the 1990s. Daily soil moisture observations have been quality controlled using the North American Soil Moisture Database QAQC algorithm. The database is designed to facilitate observationally-driven investigations of land-atmosphere interactions, validation of the accuracy of soil moisture simulations in global land surface models, satellite calibration/validation for SMOS and SMAP, and an improved understanding of how soil moisture influences climate on seasonal to interannual timescales. This paper provides some examples of how the NASMD has been utilized to enhance understanding of land-atmosphere interactions in the U.S. Great Plains.

This study examined the relationship between team emotional intelligence, quality of team interactions, and gender. Psychiatry clerkship students participating in Team-Based Learning (TBL, n = 484) or no TBL (control, n = 265) completed the Workgroup Emotional Intelligence Profile (WEIP-S) and the Team Performance Scale (TPS). Significant correlations (p < 0.01) existed between quality of team interactions (i.e., TPS) and team emotional intelligence (i.e., WEIP-S) subscales, but not gender. Control and TBL groups experienced significant increases in WEIP-S subscales pre to post (p < 0.01, η (2) = .08), with the TBL group experiencing significantly higher gains in three of four subscales. Control group scored higher on TPS. A significant relationship exists between team emotional intelligence and quality of team interactions. Gender was unrelated to TPS or WEIP-S subscales. TBL group experienced higher gains in WEIP-S subscales while the control group experienced slightly higher TPS scores. Results suggest implications for medical educators who use TBL.

Socially Interactive and Passive Technologies Enhance Friendship Quality: An Investigation of the Mediating Roles of Online and Offline Self-Disclosure.

PubMed

Desjarlais, Malinda; Joseph, Jessica J

2017-05-01

Previous studies indicate that characteristics of social-based technologies (STs) stimulate the sharing of intimate information online, which in turn enhances the quality of friendships. In addition, intimate online self-disclosure has been positively associated with offline self-disclosure. One objective of the current study was to combine the literature and test a model which postulates that STs use stimulates online self-disclosure which facilitates offline self-disclosure and, thereby, enhances the quality of close friendships. A second objective of this study was to examine if the aforementioned model applies to two categories of STs, including socially interactive technologies (SITs; e.g., instant messaging) and socially passive technologies (SPTs; e.g., reading posts on social networking sites). An online survey was conducted with 212 young adults between 18 and 25 years of age. The proposed indirect positive effects of SITs and SPTs use on the quality of friendships were supported. The positive effect of SITs use on the quality of friendships was explained entirely by the young adults' disclosure of personal information when using SITs which facilitated intimate self-disclosure during face-to-face interactions. Although there was not a direct effect of SPTs use on the quality of friendships, SPTs use was positively related to SPTs self-disclosure, which had a positive effect on offline self-disclosure. The current study enhances our understanding regarding the positive effects associated with the use of STs among close friends and identifies the contribution of online self-disclosure for offline interactions.

The main aim of this study was to investigate the quality of social interaction between 60 foster parents and their foster children compared to a group of 55 non-foster families at 2 (T1) and again at 3 (T2) years of age. Video observations were used to investigate child-parent interaction at both time-points. "This is My Baby" interview was administered to investigate foster parents' commitment at T1. The main results revealed significant group differences at T1 on all child-parent social interaction measures, although not at T2. Further, a significant group by time interaction was identified for parental sensitivity, revealing a positive development over time in the foster group. Finally, a significant positive relation was found between commitment at T1 and parental sensitivity. The results convey an optimistic view of the possibilities for foster dyads to develop positive patterns of social interaction over time.

A dementia care management intervention: which components improve quality?

2012-02-01

To analyze whether types of providers and frequency of encounters are associated with higher quality of care within a coordinated dementia care management (CM) program for patients and caregivers. Secondary analysis of intervention-arm data from a dementia CM cluster-randomized trial, where intervention participants interacted with healthcare organization care managers (HOCMs), community agency care managers (CACMs), and/ or healthcare organization primary care providers (HOPCPs) over 18 months. Encounters of 238 patient/caregivers (dyads) with HOCMs, CACMs, and HOPCPs were abstracted from care management electronic records. The quality domains of assessment, treatment, education/support, and safety were measured from medical record abstractions and caregiver surveys. Mean percentages of met quality indicators associated with exposures to each provider type and frequency were analyzed using multivariable regression, adjusting for participant characteristics and baseline quality. As anticipated, for all 4 domains, the mean percentage of met dementia quality indicators was 15.5 to 47.2 percentage points higher for dyads with HOCM--only exposure than for dyads with none (all P < .008); not anticipated were higher mean percentages with increasing combinations of provider-type exposure-up to 73.7 percentage points higher for safety (95% confidence interval 65.2%-82.1%) with exposure to all 3 provider types compared with no exposure. While greater frequency of HOCM-dyad encounters was associated with higher quality (P < .04), this was not so for other provider types. HOCMs' interactions with dyads was essential for dementia care quality improvement. Additional coordinated interactions with primary care and community agency staff yielded even higher quality.

2008-08-01

To evaluate the quality of web-based information on cocaine use and addiction and to investigate potential content quality indicators. Three keywords: cocaine, cocaine addiction and cocaine dependence were entered into two popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability and content quality. "Health on the Net" (HON) quality label, and DISCERN scale scores aiding people without content expertise to assess quality of written health publication were used to verify their efficiency as quality indicators. Of the 120 websites identified, 61 were included. Most were commercial sites. The results of the study indicate low scores on each of the measures including content quality. A global score (the sum of accountability, interactivity, content quality and aesthetic criteria) appeared as a good content quality indicator. While cocaine education websites for patients are widespread, their global quality is poor. There is a need for better evidence-based information about cocaine use and addiction on the web. The poor and variable quality of web-based information and its possible impact on physician-patient relationship argue for a serious provider for patient talk about the health information found on Internet. Internet sites could improve their content using the global score as a quality indicator.

Multiple Interactive Pollutants in Water Quality Trading

NASA Astrophysics Data System (ADS)

Sarang, Amin; Lence, Barbara J.; Shamsai, Abolfazl

2008-10-01

Efficient environmental management calls for the consideration of multiple pollutants, for which two main types of transferable discharge permit (TDP) program have been described: separate permits that manage each pollutant individually in separate markets, with each permit based on the quantity of the pollutant or its environmental effects, and weighted-sum permits that aggregate several pollutants as a single commodity to be traded in a single market. In this paper, we perform a mathematical analysis of TDP programs for multiple pollutants that jointly affect the environment (i.e., interactive pollutants) and demonstrate the practicality of this approach for cost-efficient maintenance of river water quality. For interactive pollutants, the relative weighting factors are functions of the water quality impacts, marginal damage function, and marginal treatment costs at optimality. We derive the optimal set of weighting factors required by this approach for important scenarios for multiple interactive pollutants and propose using an analytical elasticity of substitution function to estimate damage functions for these scenarios. We evaluate the applicability of this approach using a hypothetical example that considers two interactive pollutants. We compare the weighted-sum permit approach for interactive pollutants with individual permit systems and TDP programs for multiple additive pollutants. We conclude by discussing practical considerations and implementation issues that result from the application of weighted-sum permit programs.

We examined whether risks of 32 birth defects were higher than expected in the presence of overweight or obese body mass index (BMI) and low diet quality, based on estimating individual and joint effects of these factors and calculating relative excess risk due to interaction. Analyses included mothers of 20,250 cases with birth defects and 8617 population-based controls without birth defects born from 1997 to 2009 and interviewed for the National Birth Defects Prevention Study. We used logistic regression to generate adjusted odds ratios (AORs) reflecting the combined effects of BMI and diet quality. We focused analyses on 16 birth defects (n = 11,868 cases, 8617 controls) for which initial results suggested an association with BMI or diet quality. Relative to the reference group (normal weight women with not low diet quality, i.e., >lowest quartile), AORs for low diet quality among normal weight women tended to be >1, and AORs for overweight and obese women tended to be stronger among women who had low diet quality than not low diet quality. For 9/16 birth defects, AORs for obese women who had low diet quality-the group we hypothesized to have highest risk-were higher than other stratum-specific AORs. Most relative excess risk due to interactions were positive but small (<0.5), with confidence intervals that included zero. These findings provide evidence for the hypothesis of highest birth defect risks among offspring to women who are obese and have low diet quality but insufficient evidence for an interaction of these factors in their contribution to risk. © 2015 Wiley Periodicals, Inc.

2017-02-01

The quality of wheat depends on a large complex of genes and environmental factors. The objective of this study was to identify quantitative trait loci controlling technological quality traits and their stability across environments, and to assess the impact of interaction between alleles at loci Glu-1 and Glu-3 on grain quality. DH lines were evaluated in field experiments over a period of 4 years, and genotyped using simple sequence repeat markers. Lines were analysed for grain yield (GY), thousand grain weight (TGW), protein content (PC), starch content (SC), wet gluten content (WG), Zeleny sedimentation value (ZS), alveograph parameter W (APW), hectolitre weight (HW), and grain hardness (GH). A number of QTLs for these traits were identified in all chromosome groups. The Glu-D1 locus influenced TGW, PC, SC, WG, ZS, APW, GH, while locus Glu-B1 affected only PC, ZS, and WG. Most important marker-trait associations were found on chromosomes 1D and 5D. Significant effects of interaction between Glu-1 and Glu-3 loci on technological properties were recorded, and in all types of this interaction positive effects of Glu-D1 locus on grain quality were observed, whereas effects of Glu-B1 locus depended on alleles at Glu-3 loci. Effects of Glu-A3 and Glu-D3 loci per se were not significant, while their interaction with alleles present at other loci encoding HMW and LMW were important. These results indicate that selection of wheat genotypes with predicted good bread-making properties should be based on the allelic composition both in Glu-1 and Glu-3 loci, and confirm the predominant effect of Glu-D1d allele on technological properties of wheat grains.

Cardiovascular disease is the leading cause of mortality and morbidity in the United States. Primary care teams can be best suited to improve quality of care and lower costs for patients with cardiovascular disease. This study evaluates the associations between primary care team communication, interaction, and coordination (ie, social networks); quality of care; and costs for patients with cardiovascular disease. Using a sociometric survey, 155 health professionals from 31 teams at 6 primary care clinics identified with whom they interact daily about patient care. Social network analysis calculated variables of density and centralization representing team interaction structures. Three-level hierarchical modeling evaluated the link between team network density, centralization, and number of patients with a diagnosis of cardiovascular disease for controlled blood pressure and cholesterol, counts of urgent care visits, emergency department visits, hospital days, and medical care costs in the previous 12 months. Teams with dense interactions among all team members were associated with fewer hospital days (rate ratio [RR] = 0.62; 95% CI, 0.50-0.77) and lower medical care costs (-$556; 95% CI, -$781 to -$331) for patients with cardiovascular disease. Conversely, teams with interactions revolving around a few central individuals were associated with increased hospital days (RR = 1.45; 95% CI, 1.09-1.94) and greater costs ($506; 95% CI, $202-$810). Team-shared vision about goals and expectations mediated the relationship between social network structures and patient quality of care outcomes. Primary care teams that are more interconnected and less centralized and that have a shared team vision are better positioned to deliver high-quality cardiovascular disease care at a lower cost. © 2015 Annals of Family Medicine, Inc.

Infant massage programs have proved to be effective in enhancing post-natal development of highly risk infants, such as preterm newborns and drug or HIV exposed children. Less studies have focused on the role of infant massage in supporting the co-construction of early adult–child relationships. In line with this lack of literature, the present paper reports on a pilot study aimed at investigating longitudinally the quality of mother–child interactions, with specific reference to emotional availability (EA), in a group of mother–child pairs involved in infant massage classes. Moreover, associations between mother–child EA, maternal wellbeing, marital adjustment, and social support were also investigated, with the hypothesis to find a link between low maternal distress, high couple satisfaction and high perceived support and interactions of better quality in the dyads. The study involved 20 mothers and their children, aged between 2 and 7 months, who participated to infant massage classes. The assessment took place at three stages: at the beginning of massage course, at the end of it and at 1-month follow-up. At the first stage of assessment self-report questionnaires were administered to examine the presence of maternal psychiatric symptoms (SCL-90-R), perceived social support (MSPSS), and marital adjustment (Dyadic Adjustment Scale); dyadic interactions were observed and rated with the Emotional Availability Scales (Biringen, 2008) at each stage of data collection. The results showed a significant improvement in the quality of mother–child interactions, between the first and the last evaluation, parallel to the unfolding of the massage program, highlighting a general increase in maternal and child’s EA. The presence of maternal psychological distress resulted associated with less optimal mother–child emotional exchanges, while the hypothesis regarding couple satisfaction and social support influence were not confirmed. These preliminary results, if replicated, seem to sustain the usefulness of infant massage and the importance of focusing on early mother–infant interactions. PMID:28144222

Background Pharmaceutical company representatives likely influence the prescribing habits and professional behaviors of physicians. The objective of this study was to systematically review the association between physicians’ interactions with pharmaceutical companies and their clinical practices. Methods We used the standard systematic review methodology. Observational and experimental study designs examining any type of targeted interaction between practicing physicians and pharmaceutical companies were eligible. The search strategy included a search of MEDLINE and EMBASE databases up to July 2016. Two reviewers selected studies, abstracted data, and assessed risk of bias in duplicate and independently. We assessed the quality of evidence using the GRADE approach. Results Twenty articles reporting on 19 studies met our inclusion criteria. All of these studies were conducted in high-income countries and examined different types of interactions, including detailing, industry-funded continuing medical education, and receiving free gifts. While all included studies assessed prescribing behaviors, four studies also assessed financial outcomes, one assessed physicians’ knowledge, and one assessed their beliefs. None of the studies assessed clinical outcomes. Out of the 19 studies, 15 found a consistent association between interactions promoting a medication, and inappropriately increased prescribing rates, lower prescribing quality, and/or increased prescribing costs. The remaining four studies found both associations and lack of significant associations for the different types of exposures and drugs examined in the studies. A meta-analysis of six of these studies found a statistically significant association between exposure and physicians’ prescribing behaviors (OR = 2.52; 95% CI 1.82–3.50). The quality of evidence was downgraded to moderate for risk of bias and inconsistency. Sensitivity analysis excluding studies at high risk of bias did not substantially change these results. A subgroup analysis did not find a difference by type of exposure. Conclusion There is moderate quality evidence that physicians’ interactions with pharmaceutical companies are associated with their prescribing patterns and quality. PMID:28406971

This report describes a secondary analysis of data from a comprehensive intervention project which included training and structural changes in three Baby Homes in St. Petersburg, Russian Federation. Multiple mediator models were tested according to the R.M. Baron and D.A. Kenny () causal-steps approach to examine whether caregiver-child interaction quality, number of caregiver transitions, and group size mediated the effects of the intervention on children's attachment behaviors and physical growth. The study utilized a subsample of 163 children from the original Russian Baby Home project, who were between 11 and 19 months at the time of assessment. Results from comparisons of the training and structural changes versus no intervention conditions are presented. Caregiver-child interaction quality and number of caregiver transitions fully mediated the association between intervention condition and attachment behavior. No other mediation was found. Results suggest that the quality of interaction between caregivers and children in institutional care is of primary importance to children's development, but relationship context may play a less direct mediational role, supporting caregiver-child interactions. © 2017 Michigan Association for Infant Mental Health.

Problematic mobile phone use (PMPU) is a risk factor for both adolescents' sleep quality and mental health. It is important to examine the potential negative health effects of PMPU exposure. This study aims to evaluate PMPU and its association with mental health in Chinese college students. Furthermore, we investigated how sleep quality influences this association. In 2013, we collected data regarding participants' PMPU, sleep quality, and mental health (psychopathological symptoms, anxiety, and depressive symptoms) by standardized questionnaires in 4747 college students. Multivariate logistic regression analysis was applied to assess independent effects and interactions of PMPU and sleep quality with mental health. PMPU and poor sleep quality were observed in 28.2% and 9.8% of participants, respectively. Adjusted logistic regression models suggested independent associations of PMPU and sleep quality with mental health ( p < 0.001). Further regression analyses suggested a significant interaction between these measures ( p < 0.001). The study highlights that poor sleep quality may play a more significant role in increasing the risk of mental health problems in students with PMPU than in those without PMPU.

Procedural justice and quality of life in compensation processes.

There is considerable evidence that being involved in compensation processes has a negative impact on claimants' health. Previous studies suggested that this negative effect is caused by a stressful compensation process: claimants suffered from a lack of communication, a lack of information, and feelings of distrust. However, these rather qualitative findings have not been quantitatively investigated yet. This observational study aimed to fill this gap of knowledge, investigating the claimants' perceived fairness of the compensation process, the provided information, and the interaction with lawyers and insurance companies, in relation to the claimants' quality of life. Participants were individuals injured in traffic accidents, older than 18 years, who were involved in a compensation process in the Netherlands. They were recruited by three claims settlement offices. Outcome measures were procedural, interactional, and informational justice, and quality of life. Participants (n=176) perceived the interaction with lawyers to be fairer than the interaction with insurance companies (p<.001). The length of hospital stay was positively associated with procedural justice (β=.31, p<.001). Having trunk/back injury was negatively related to procedural justice (β=-.25, p=.001). Whiplash injury and length of time involved in the claim process were not associated with any of the justice scales. Finally, procedural justice was found to be positively correlated with quality of life (rs=.22, p=.004). The finding that the interaction with insurance companies was considered less fair than the interaction with lawyers may imply that insurers could improve their interaction with claimants, e.g. by communicating more directly. The result that claimants with mild injuries and with trunk/back injuries considered the compensation process to be less fair than those with respectively severe injuries and injuries to other body parts suggests that especially the former two require an attentive treatment. Finally, the fact that procedural justice was positively correlated with quality of life could implicate that it is possible to improve claimants' health in compensation processes by enhancing procedural justice, e.g. by increasing the ability for claimants to express their views and feelings and by involving claimants in the decision-making process.

In young children with type 1 diabetes mellitus (T1DM), parents have complete responsibility for the diabetes-management. In toddlers and (pre)schoolers, the tasks needed to achieve optimal blood glucose control may interfere with normal developmental processes and could negatively affect the quality of parent-child interaction. Several observational instruments are available to measure the quality of the parent-child interaction. However, no observational instrument for diabetes-specific situations is available. Therefore, the aim of the present study was to develop a qualitative observation instrument, to be able to assess parent-child interaction during diabetes-specific situations. First, in a pilot study (n = 15), the observation instrument was developed in four steps: (a) defining relevant diabetes-specific situations; (b) videotaping these situations; (c) describing all behaviors in a qualitative observation instrument; (d) evaluating usability and reliability. Next, we examined preliminary validity (total n = 77) by testing hypotheses about correlations between the observation instrument for diabetes-specific situations, a generic observation instrument and a behavioral questionnaire. The observation instrument to assess parent-child interaction during diabetes-specific situations, which consists of ten domains: "emotional involvement", "limit setting", "respect for autonomy", "quality of instruction", "negative behavior", "avoidance", "cooperative behavior", "child's response to injection", "emphasis on diabetes", and "mealtime structure", was developed for use during a mealtime situation (including glucose monitoring and insulin administration). The present study showed encouraging indications for the usability and inter-rater reliability (weighted kappa was 0.73) of the qualitative observation instrument. Furthermore, promising indications for the preliminary validity of the observation instrument for diabetes-specific situations were found (r ranged between |.24| and |.45| for significant correlations and between |.10| and |.23| for non-significant trends). This observation instrument could be used in future research to (a) test whether parent-child interactions are associated with outcomes (like HbA1c levels and psychosocial functioning), and (b) evaluate interventions, aimed at optimizing the quality of parent-child interactions in families with a young child with T1DM.

Demographic characteristics, family financial strain, neighborhood-level economic disadvantage, and state of residence were tested as predictors of observed warmth, hostility, and self-reported marital quality. Participants were 202 married African American couples who resided in a range of neighborhood contexts. Neighborhood-level economic disadvantage predicted lower warmth during marital interactions, as did residence in the rural south. Consistent with the family stress model (e.g., Conger & Elder, 1994), family financial strain predicted lower perceived marital quality. Unexpectedly, neighborhood-level economic disadvantage predicted higher marital quality. Social comparison processes and degree of exposure to racially based discrimination are considered as explanations for this unexpected result. The importance of context in relationship outcomes is highlighted. PMID:17955056

Dual redundant arm system operational quality measures and their applications - Static measures

Lee, Sukhan; Kim, Sungbok

1990-01-01

The authors present dual-arm system static operational quality measures which quantify the efficiency and capability of a dual-arm system in generating Cartesian velocities and static forces. First, they define and analyze the kinematic interactions between the two arms incurred by the various modes of dual-arm cooperation, such as transport, assembly, and grasping modes of cooperation, and specify the kinematic constraints imposed on individual arms in Cartesian space due to the kinematic interactions. Dual-arm static manipulability is presented. Finally, dual-arm operational quality is scaled by a task-oriented operational quality measure (TOQs) obtained by the comparison between the desired and actual static manipulabilities. TOQs is used in the optimization of dual-arm joint configurations. Simulation results are shown.

Maternal Resolution of Grief After Preterm Birth: Implications for Infant Attachment Security

Clements, Melissa; Poehlmann, Julie

2011-01-01

OBJECTIVE: This study explored the association between mothers' unresolved grief regarding their infant's preterm birth and infant-mother attachment security. We hypothesized that mothers with unresolved grief would be more likely to have insecurely attached infants at 16 months and that this association would be partially mediated by maternal interaction quality. METHODS: This longitudinal study focused on 74 preterm infants (age of <36 weeks) and their mothers who were part of a larger study of high-risk infants. The present analysis included assessment of neonatal and socioeconomic risks at NICU discharge; maternal depression, Reaction to Preterm Birth Interview findings, and quality of parenting at a postterm age of 9 months; and infant-mother attachment at postterm age of 16 months. Associations among findings of grief resolution with the Reaction to Preterm Birth Interview, quality of parenting interactions, and attachment security were explored by using relative risk ratios and logistic and multivariate regression models. RESULTS: The relative risk of developing insecure attachment when mothers had unresolved grief was 1.59 (95% confidence interval: 1.03–2.44). Controlling for covariates (adjusted odds ratio: 2.94), maternal feelings of resolved grief regarding the preterm birth experience were associated with secure infant-mother attachment at 16 months. Maternal grief resolution and interaction quality were independent predictors of attachment security. CONCLUSION: Maternal grief resolution regarding the experience of preterm birth and the quality of maternal interactions have important implications for emerging attachment security for infants born prematurely.

Child healthy development is largely influenced by parent-child interaction and a secure parent-child attachment is predictively associated with positive outcomes in numerous domains of child development. However, the parent-child relationship can be affected by several psychosocial and socio-demographic risk factors that undermine its quality and in turn play a negative role in short and long term child psychological health. Prevention and intervention programs that support parenting skills in at-risk families can efficiently reduce the impact of risk factors on mother and child psychological health. This study examines predictors of mother-child interaction quality and child attachment security in a sample of first-time mothers with psychosocial and/or socio-demographic risk factors. Forty primiparous women satisfying specific risk criteria participated in a longitudinal study with their children from pregnancy until 18 month of child age. A multiple psychological and socioeconomic assessment was performed. The Emotional Availability Scales were used to measure the quality of emotional exchanges between mother and child at 12 months and the Attachment Q-Sort served as a measure of child attachment security at 18 months. Results highlight both the effect of specific single factors, considered at a continuous level, and the cumulative risk effect of different co-occurring factors, considered at binary level, on mother-child interaction quality and child attachment security. Implication for the selection of inclusion criteria of intervention programs that support parenting skills in at-risk families are discussed.

Identification of water quality management policy of watershed system with multiple uncertain interactions using a multi-level-factorial risk-inference-based possibilistic-probabilistic programming approach.

In this study, a multi-level-factorial risk-inference-based possibilistic-probabilistic programming (MRPP) method is proposed for supporting water quality management under multiple uncertainties. The MRPP method can handle uncertainties expressed as fuzzy-random-boundary intervals, probability distributions, and interval numbers, and analyze the effects of uncertainties as well as their interactions on modeling outputs. It is applied to plan water quality management in the Xiangxihe watershed. Results reveal that a lower probability of satisfying the objective function (θ) as well as a higher probability of violating environmental constraints (q i ) would correspond to a higher system benefit with an increased risk of violating system feasibility. Chemical plants are the major contributors to biological oxygen demand (BOD) and total phosphorus (TP) discharges; total nitrogen (TN) would be mainly discharged by crop farming. It is also discovered that optimistic decision makers should pay more attention to the interactions between chemical plant and water supply, while decision makers who possess a risk-averse attitude would focus on the interactive effect of q i and benefit of water supply. The findings can help enhance the model's applicability and identify a suitable water quality management policy for environmental sustainability according to the practical situations.

The physical environment mediates male harm and its effect on selection in females.

Recent experiments indicate that male preferential harassment of high-quality females reduces the variance in female fitness, thereby weakening natural selection through females and hampering adaptation and purging. We propose that this phenomenon, which results from a combination of male choice and male-induced harm, should be mediated by the physical environment in which intersexual interactions occur. Using Drosophila melanogaster , we examined intersexual interactions in small and simple (standard fly vials) versus slightly more realistic (small cages with spatial structure) environments. We show that in these more realistic environments, sexual interactions are less frequent, are no longer biased towards high-quality females, and that overall male harm is reduced. Next, we examine the selective advantage of high- over low-quality females while manipulating the opportunity for male choice. Male choice weakens the viability advantage of high-quality females in the simple environment, consistent with previous work, but strengthens selection on females in the more realistic environment. Laboratory studies in simple environments have strongly shaped our understanding of sexual conflict but may provide biased insight. Our results suggest that the physical environment plays a key role in the evolutionary consequences of sexual interactions and ultimately the alignment of natural and sexual selection. © 2017 The Author(s).

Probing the interaction between nanoparticles and lipid membranes by quartz crystal microbalance with dissipation monitoring

NASA Astrophysics Data System (ADS)

Yousefi, Nariman; Tufenkji, Nathalie

2016-12-01

There is increasing interest in using quartz crystal microbalance with dissipation monitoring (QCM-D) to investigate the interaction of nanoparticles (NPs) with model surfaces. The high sensitivity, ease of use and the ability to monitor interactions in real-time has made it a popular technique for colloid chemists, biologists, bioengineers and biophysicists. QCM-D has been recently used to probe the interaction of NPs with supported lipid bilayers (SLBs) as model cell membranes. The interaction of NPs with SLBs is highly influenced by the quality of the lipid bilayers. Unlike many surface sensitive techniques, using QCM-D, the quality of SLBs can be assessed in real-time, hence QCM-D studies on SLB-NP interactions are less prone to the artefacts arising from bilayers that are not well formed. The ease of use and commercial availability of a wide range of sensor surfaces also have made QCM-D a versatile tool for studying NP interactions with lipid bilayers. In this review, we summarize the state-of-the-art on QCM-D based techniques for probing the interactions of NPs with lipid bilayers.
