Some Effects of Proportions on Group Life: Skewed Sex Ratios and Responses to Token Women

Proportions, that is, relative numbers of socially and culturally different people in a group, are seen as critical in shaping interaction dinamics, and four group types are identified in the basis of varying proportional compositions. "Skewed" groups contain a large preponderance of one type (the numerical "dominants") over another (the rare "tokens"). A framework is developed for conceptualizing the processes that occur between dominants and tokens. Three perceptual phenomena are associated with tokens: visibility (tokens capture a disproportionate awareness share), polarization (differences between tokens and dominants are exaggerated), and assimilation (tokens' attributes are distorted to fit preexisting generalizations about their social type). Visibility generates performance pressures; polarization leads dominants to heighten their group boundaries; and assimilation leads to the tokens' role entrapment. Illustrations are drawn from a field study in a large industrial corporation. Concepts are extended to tokens of all kinds, and research issues are identified.
The New Scroll Digital Devices, Bible Study and Worship

Using survey and focus group methodology, this study examined what highly religious people think about mobile technology as an enhancement to the individual and corporate spiritual life. Results indicated that even church members over 60 years old embraced newer technologies both within their place of worship as well as at home. Sunday school and Bible study teachers were more comfortable and enthusiastic about the uses of mobile technology for spiritual growth than nonteachers. Participants in the focus group not only understood the benefit of mobile technology but also acknowledged the distraction that often occurred. Regardless of their enthusiasm toward mobile technology, respondents also were adamant that the scripture had special meaning whether viewed electronically or within the well-worn pages of the family Bible.
Substance use and personality disorders

Abstract Studies in both population- and clinic-based settings show a higher prevalence of personality disorders among people with substance use disorders than among the general population, with particular prominence of antisocial and borderline personality disorders. Professionals providing treatment for people with drug and alcohol problems are highly accustomed to working with people with personality disorders, as estimates suggest that over half the patient population of such services will meet criteria for one or more personality disorders. There is evidence to suggest that people with personality disorders are able to gain as much benefit from standard evidence-based treatments for substance use disorders as people without personality disorder. Special treatment approaches designed for people with both personality disorders and substance use disorders are in the early stages of evaluation. Substance misusers seek and receive help in many settings other than the specialist clinics typically described in research studies; these include primary care, the non-statutory sector and self-help movements. The particular benefits and drawbacks of these different services for people with concurrent personality disorder are of interest, but are currently unknown.
Occupationaljustice and Client-Centred Practice: A Dialogue in Progress

Background. This paper describes an ongoing, international dialogue about the relationship between occupation, justice, and client-centred practice, prompted by the question: How do occupational therapists work for justice? Methods. The authors critically reflect on their own dialogue and culturally situated interests, dialogues with workshop participants, and a literature review. Results. Four cases of occupational injustice are proposed: occupational alienation, occupational deprivation, occupational marginalization, and occupational imbalance. The naming of these occupational injustices suggests four occupational rights: to experience meaning and enrichment in one's occupations; to participate in a range of occupations for health and social inclusion; to make choices and share decision-making power in daily life; and to receive equal privileges for diverse participation in occupations. Practice Implications. Since silence implies compliance with the status quo, the authors encourage occupational therapists to develop their own dialogue about occupational injustices in order to address them openly with others. Dialogue about occupational justice is timely as occupational therapists around the world articulate what distinguishes this numerically small, rather invisible profession and its contributions to individuals, populations, and societies.
Interferon-gamma modifies cytokine release in vitro by monocytes from surgical patients.

BACKGROUND Treatment with interferon-gamma (IFN-gamma), a key mediator for adequate forward-regulatory monocyte immune capability, has been advocated to overcome posttraumatic mononuclear leukocyte paralysis. Conversely, IFN-gamma also is a potent proinflammatory mediator contributing to capillary leakage in sepsis-driven organ failure. The objective of this investigation was to further define the potential of IFN-gamma as a modifier of monocyte activity before and after injury. METHODS Whole blood samples from 19 patients (7 female and 12 male patients; age, 68 +/- 5 years) before and after cardiac surgery with extracorporeal circulation were incubated under continuous rotation with lipopolysaccharide for 12 hours in the presence or absence of human recombinant IFN-gamma. Pro- and anti-inflammatory cytokines were determined in the plasma. RESULTS Lipopolysaccharide-induced release of tumor necrosis factor-alpha, interleukin (IL)-6, IL-12, and IL-1Ra, and prostaglandin E2 was clearly augmented with IFN-gamma most strikingly postoperatively (p < 0.05). There was no effect on IL-1beta, neopterin, and soluble tumor necrosis factor-R release. CONCLUSION Thus there is a wide spectrum of IFN-gamma activity on monocyte activation including anti-inflammatory properties. Since cellular preactivation facilitates monocyte reactivity toward IFN-gamma, we conclude that exogenous administration should be effective but must be carried out with great caution in patients with profound inflammation.
Vitamin D supplementation of initially vitamin D‐deficient mice diminishes lung inflammation with limited effects on pulmonary epithelial integrity

In disease settings, vitamin D may be important for maintaining optimal lung epithelial integrity and suppressing inflammation, but less is known of its effects prior to disease onset. Female BALB/c dams were fed a vitamin D3‐supplemented (2280 IU/kg, VitD+) or nonsupplemented (0 IU/kg, VitD−) diet from 3 weeks of age, and mated at 8 weeks of age. Male offspring were fed the same diet as their mother. Some offspring initially fed the VitD− diet were switched to a VitD+ diet from 8 weeks of age (VitD−/+). At 12 weeks of age, signs of low‐level inflammation were observed in the bronchoalveolar lavage fluid (BALF) of VitD− mice (more macrophages and neutrophils), which were suppressed by subsequent supplementation with vitamin D3. There was no difference in the level of expression of the tight junction proteins occludin or claudin‐1 in lung epithelial cells of VitD+ mice compared to VitD− mice; however, claudin‐1 levels were reduced when initially vitamin D‐deficient mice were fed the vitamin D3‐containing diet (VitD−/+). Reduced total IgM levels were detected in BALF and serum of VitD−/+ mice compared to VitD+ mice. Lung mRNA levels of the vitamin D receptor (VDR) were greatest in VitD−/+ mice. Total IgG levels in BALF were greater in mice fed the vitamin D3‐containing diet, which may be explained by increased activation of B cells in airway‐draining lymph nodes. These findings suggest that supplementation of initially vitamin D‐deficient mice with vitamin D3 suppresses signs of lung inflammation but has limited effects on the epithelial integrity of the lungs.
Premuneration Values and Investments in Matching Markets

We analyze a model in which agents make investments and then match into pairs to create a surplus. The agents can make transfers to reallocate their pretransfer ownership claims on the surplus. Mailath, Postlewaite, and Samuelson (2013) showed that when investments are unobservable, equilibrium investments are generally inefficient. In this paper we work with a more structured model that is sufficiently tractable to analyze the nature of the investment inefficiencies. We provide conditions under which investment is inefficiently high or low and conditions under which changes in the pretransfer ownership claims on the surplus will be Pareto improving, as well as examine how the degree of heterogeneity on either side of the market affects investment efficiency.
Neural correlates of risk perception: HIV vs. leukemia

Field studies on HIV risk perception suggest that people may rely on impressions they have about the safety of their partner. Previous studies show that individuals perceived as “risky” regarding HIV elicit a differential brain response in both earlier (~200–350 ms) and later (~350–700 ms) time windows compared to those perceived as safe. This raises the question whether this event-related brain potential (ERP) response is specific to contagious life-threatening diseases or a general mechanism triggered by life-threatening but non-contagious diseases. In the present study, we recorded dense sensor EEG while participants (N = 36) evaluated photographs of unacquainted individuals for either HIV or leukemia risk. The ERP results replicated previous findings revealing earlier and later differential brain responses towards individuals perceived as high risk for HIV. However, there were no significant ERP differences for high vs. low leukemia risk. Rather than reflecting a generic response to disease, the present findings suggest that intuitive judgments of HIV risk are at least in part specific to sexually transmitted diseases.
Blockade of Endogenous Neurotrophic Factors Prevents the Androgenic Rescue of Rat Spinal Motoneurons

Target-derived neurotrophic factors are assumed to regulate motoneuron cell death during development but remain unspecified. Motoneuron cell death in the spinal nucleus of the bulbocavernosus (SNB) of rats extends postnatally and is controlled by androgens. We exploited these features of the SNB system to identify endogenously produced trophic factors regulating motoneuron survival. Newborn female rat pups were treated with the androgen, testosterone propionate, or the oil vehicle alone. In addition, females received trophic factor antagonists delivered either into the perineum (the site of SNB target muscles) or systemically. Fusion molecules that bind and sequester the neurotrophins (trkA-IgG, trkB-IgG, and trkC-IgG) were used to block activation of neurotrophin receptors, and AADH-CNTF was used to antagonize signaling through the ciliary neurotrophic factor receptor-α (CNTFRα). An acute blockade of trkB, trkC, or CNTFRα prevented the androgenic sparing of SNB motoneurons when antagonists were delivered to the perineum. Trophic factor antagonists did not significantly reduce SNB motoneuron number when higher doses were injected systemically. These findings demonstrate a requirement for specific, endogenously produced trophic factors in the androgenic rescue of SNB motoneurons and further suggest that trophic factor interactions at the perineum play a crucial role in masculinization of this neural system.
Understanding the “Why” as Well as the “How”: Service Performance is a Function of Prosocial Motives and Emotional Labor

Which employees tend to better perform with customers? We suggest a combination of individual differences; specifically, we consider both why employees are working (prosocial motivation) and how (emotional labor). Deep acting should enhance the positive relationship between prosocial motivation and performance, while surface acting should dampen this relationship. Using a field sample of 214 grocery clerks and supervisor ratings of interpersonal performance with customers, we did not find the amplifying effect of deep acting. We do find the dampening effect for surface acting, such that surface acting buffers those with low prosocial motives, presumably by allowing them to “act” like they want to help others. This helps to explain the weak relationship of prosocial motives with performance and suggests implications for research and practice.
Gender, Race, and Perceived Environmental Risk: The “White Male” Effect in Cancer Alley, LA

Research on risk perceptions are replete with race- and gender-specific hypotheses attempting to account for attitudinal variation. However, race and gender differences may mask more notable patterns across subgroups, patterns that lie at the intersection of race and gender. Recent national studies suggest that being a White male leads to lower risk perceptions and greater willingness to accept risks. This article extends this research by examining the “White male” effect in a chronically polluted context, an area where industrial pollution is palpable and well-documented. Data are drawn from a survey of a population living in “Cancer Alley,” a stretch of the Mississippi River from Baton Rouge to New Orleans. We find that women more than men and Blacks more than Whites perceive environmental risks as serious. Further, evidence suggests that these differences are mostly due to the relatively extreme perceptions of risk accepting White males and risk adverse Black females. After controlling for select varia.
“It's Not What I Expected”

Although estimates are that only about half of youth mentoring relationships established through formal programs last beyond a few months, almost no attention has been paid to understanding mentoring relationship failures. In-depth semistructured interviews were conducted with 20 adult and 11 adolescent male and female participants in a community-based one-to-one mentoring program whose relationships ended early. Line-by-line coding and a narrative approach to a thematic analysis of the interview transcripts yielded six salient factors that contributed to the demise of these mentoring relationships: (a) mentor or protégé abandonment, (b) perceived lack of protégé motivation, (c) unfulfilled expectations, (d) deficiencies in mentor relational skills, including the inability to bridge cultural divides, (e) family interference, and (f) inadequate agency support.
On the Capacity of Multiple-Antenna Systems and Parallel Gaussian Channels With Amplitude-Limited Inputs

We propose upper and lower bounds on the capacity of multiple-input multiple-output (MIMO) systems with amplitude-limited inputs. The results are derived by considering an equivalent channel via singular value decomposition, and by enlarging and reducing the corresponding feasible region of the channel input vector, for the upper and lower bounds, respectively. We analytically characterize the asymptotic behavior of the derived bounds for high and low noise levels, and study the gap between them. We also consider parallel Gaussian channels with peak and average power-constrained inputs. For such channels, the capacity-achieving distribution has been reported in the literature to be discrete, which can be computed using numerical optimization techniques. However, there is no closed-form expression and finding the capacity-achieving distribution is computationally tedious. With this motivation, we derive approximate expressions for the capacity at low and high noise variance levels. We illustrate our findings on both MIMO channels and parallel Gaussian channels via several numerical examples.
Social Identity and Achievement Gaps: Evidence From an Affirmation Intervention

Abstract One provocative explanation for the continued persistence of minority achievement gaps involves the performance-dampening anxiety thought to be experienced by minority students in highly evaluative settings (i.e., “stereotype threat”). Recent field-experimental studies suggest that modest, low-cost “buffering” interventions informed by this phenomenon may be highly effective at reducing minority achievement gaps. This field-experimental study evaluates such an intervention in which students complete a self-directed “self affirmation” exercise that encourages them to identify and reflect upon their core personal values. This within-classroom randomized trial was conducted among 2,500 7th and 8th graders from six Philadelphia-area middle schools during the 2008–09 and 2009–10 academic years. Although this study failed to replicate the earlier findings indicating that the affirmation generated large increases in the academic performance of minority students, this treatment did lead to statistically significant improvements in the performance of the minority students in more supportive classroom environments. However, the treatment contrast also reduced the performance of female students in those settings.
Neuropsychological characteristics of dyslexic children

The aim of this study was to identify the neuropsychological characteristics of dyslexic children. Seventy-three children underwent neuropsychological assessment and were divided into two groups: a group with dyslexia (DG; n=39) and a control group (CG; n= 34). A general linear model showed a significant difference between the groups regarding the following abilities: reading, writing and mathematics; forward and backward digit span tasks; semantic and phonological fluency; number of completed categories and total number of cards in the Wisconsin Cards Sorting Test; as well as right and left discrimination on self and on other. These results suggest impairment in executive functions, phonological working memory and semantic memory among dyslexic children, rather than impairment of just phonological abilities, as suggested in previous studies.
Goal-directed fluid management in free flap surgery for cancer of the head and neck.

BACKGROUND Goal-directed fluid management using stroke volume variation (SVV) analysis is not well studied in free flap reconstruction surgery in patients with head and neck cancer. METHODS Patients operated due to cancer of the head and neck with free flap reconstruction during 2008-2010 and 2012-2014 in Oulu University Hospital were retrospectively evaluated to determine the impact of SVV-guided fluid management on perioperative fluid balance, postoperative complications and hospital length of stay (LOS). RESULTS A total of 104 patients were included in the study and in 48 of them SVV was used to guide intraoperative fluid management. The SVV-guided fluid management led to significant reduction in intraoperative fluid load (6070 mL vs. 8185 mL) and hospital length of stay (11.5 vs. 14.0 days). There was no difference in the number of postoperative complications between the groups. CONCLUSIONS The SVV-guided fluid management reduces fluid administration in free flap reconstruction surgery with head and neck cancer.
Exploring the relationships between principals’ life experiences and transformational leadership behaviours

The primary objective of this research study was to explore the relationships between principals’ life experiences and their transformational leadership behaviours. Over 212 public school principals completed both the lifetime leadership inventory (LLI) and the multifactor leadership questionnaire (MLQ). Exploratory and confirmatory factor analyses were used to identify the factors for validly interpreting principals’ responses for both the LLI and MLQ. Seven factors were interpreted for principal responses to the LLI while four factors best represented principals’ leadership assessed by the MLQ. Results from the analysis of the structural model representing the relationships between principals’ life experiences and their transformational leadership behaviours found that principals’ early leadership work experiences and interactions with mentors had the largest relationships with their transformational leadership behaviours. Outcomes from this study can be used as a foundation to support further investigations examining the relationship between school leaders’ life events and their leadership behaviours. In addition, these results suggest that information related to principals’ life experiences and their transformational leadership behaviours may help with decisions for admitting students to educational leadership programmes and with the recruitment of new and experienced principals.
Biomarkers of Human Exposure to Acrylamide and Relation to Polymorphisms in Metabolizing Genes

Acrylamide (AA) is formed in heat treated carbohydrate rich foods in the so-called Maillard reaction. AA is readily absorbed in the body and converted to glycidamide (GA) by epoxidation by the CYP2E1 (cytochrome P450 2E) enzyme. Both AA and GA may be detoxified through direct conjunction to glutathione by glutathione-S-transferases and GA by hydrolysis to glyceramide. Recently, we reported that biomarkers of AA exposure reflect intake of major food sources of AA; there were large interindividual variations in the blood ratio of GA-Hb/AA-Hb (GA- and AA-hemoglobin adducts). In this study we investigated whether the ratio of GA-Hb/AA-Hb in subjects could be related to polymorphic differences in genes coding for metabolizing enzymes CYP2E1, EPHX1 (microsomal epoxide hydrolase), GSTM1, GSTT1, and GSTP1, all being expected to be involved in the activation and detoxification of AA-associated adducts. We found significant associations between GSTM1 and GSTT1 genotypes and the ratio of GA-Hb/AA-Hb (p = 0.039 and p = 0.006, respectively). The ratio of GA-Hb/AA-Hb in individuals with the combined GSTM1- and GSTT1-null variants was significantly (p = 0.029) higher than those with the wild-type genotypes. Although the number of subjects was small, there were also significant associations with other combinations; CYP2E1 (Val179Val) plus GSTM1-null (p = 0.022); CYP2E1 (Val/Val), GSTM1-null plus GSTT1-null (p = 0.047); and CYP2E1 (Val/Val), GSTT1 null, EPHX1 (Tyr113Tyr) plus EPHX1 (His139Arg) (p = 0.018). Individuals with these combined genotypes had significantly higher blood ratio of GA-Hb/AA-Hb than other combinations. The observed associations correspond with what would be expected from the relative roles of these enzymes in activation and detoxification of AA, except for individuals with the EPHX1 (His139Arg) variant. The internal dose of genotoxic metabolite and also the concentration of AA in blood seem to be affected by these polymorphic genes. The genotypes and their combination may constitute useful biomarkers for the assessment of individual susceptibility to AA intake, and could add to the precision of epidemiological studies of dietary cancer.
Parenting and preschoolers’ executive functioning

A growing body of theoretical and empirical work has been attempting to answer the questions of how and how much of the effects of children’s early experience may depend on their inner characteristics. Theory and evidence suggest that some children, notably those with difficult temperaments, are more susceptible to both negative and positive aspects of parenting. The purpose of the current study was to investigate whether child temperament moderated the links between the quality of mother-infant interactions, observed when children were 1 year of age, and two components of child executive functioning (EF) at 3 years, namely impulse control and conflict EF, among 74 mother–child dyads. The results were consistent with the notion that children with more difficult temperaments may be more susceptible to maternal behaviors than children with less difficult temperaments, but only regarding the development of impulse control abilities. There was no clear evidence of such moderation for conflict EF. These results support the idea that distinct mechanisms may underlie the development of different dimensions of child EF.
