Being a Man With an Invisible Disability: College Men's Experiences

In many important ways, having a disability challenges traditional masculinity ideology. Understanding how men conceptualize and negotiate their identities both as men and as individuals with disabilities is important as men comprise a large percentage of students with disabilities, specifically invisible disabilities. The prevalence of invisible disabilities, which are disabilities not visibly apparent to others, has been increasing across all levels of education, including higher education (Marder et al., 2003). Previous studies have explored the intersections between masculinity and disability, however they were narrowly focused on men with visible impairments (e.g., Gershick & Miller, 1995) and men with chronic illnesses (e.g., Charmaz, 1995; Gibbs, 2005). Furthermore, none of these studies examined men within the context of higher education, which is important as college plays a significant role in the development of masculinity (Harris, 2010; Kimmel, 2008). The present study used grounded theory, a qualitative research approach, to explore the experiences of 22 college men with invisible disabilities through the use of in-depth interviews. This study examined how these men conceptualized their dual identities as men with invisible disabilities and how they engaged with the academic accommodations process. A grounded theory was developed providing a framework for understanding the experiences of these men that captured four central themes of (a) embodying masculinity, (b) losing masculinity, (c) preserving masculinity, and (d) cultivating masculinity.
Motivation and barriers to participation in virtual knowledge-sharing communities of practice

This paper reports the results of a qualitative study of motivation and barriers to employee participation in virtual knowledge‐sharing communities of practice at Caterpillar Inc., a Fortune 100, multinational corporation. The study indicates that, when employees view knowledge as a public good belonging to the whole organization, knowledge flows easily. However, even when individuals give the highest priority to the interests of the organization and of their community, they tend to shy away from contributing knowledge for a variety of reasons. Specifically, employees hesitate to contribute out of fear of criticism, or of misleading the community members (not being sure that their contributions are important, or completely accurate, or relevant to a specific discussion). To remove the identified barriers, there is a need for developing various types of trust, ranging from the knowledge‐based to the institution‐based trust. Future research directions and implications for KM practitioners are formulated.
Maybe She Is Relatable

In the current research, we explored whether informing women about gender bias in science, technology, engineering, and mathematics (STEM) would enhance their identification with a female scientist and whether this increased identification would in turn protect women from any adverse effects of gender bias information. We found that, relative to a control information condition, gender bias information promoted beliefs that a successful woman (but not a man) scientist had encountered bias and encouraged identification with that woman scientist. Feelings of empathic concern was an important mechanism underlying this increased identification (Experiments 2 and 3). Moreover, when presented with a man scientist, information about gender bias in STEM decreased female participants’ anticipated belonging and trust in a STEM environment, compared to participants in a control information condition (Experiment 1a and 1b). However, identifying with a woman scientist after learning about sexism in STEM fields alleviated this harmful effect. Finally, compared to those in the control condition, women college students who learned about gender bias reported greater interest in interacting with a woman STEM professor at their university (Experiment 3). Our results suggest that interventions that teach women about gender bias in STEM will help women identify with women scientists.

Feelings and phenomenal experiences

Following an initial emphasis on " cold " cognitive processes, which could be conceptualized within the computer metaphor of the information processing paradigm, social cognition researchers rediscovered " hot " cognition in the 1980's. Two decades later, their interest in the interplay of feeling and thinking is shared by researchers in decision making, cognitive psychology, and related fields. This chapter reviews what has been learned; it focuses on basic theoretical principles and empirical regularities, rather than complete coverage of the literature. We first introduce three broad approaches to the interface of feeling and thinking and subsequently evaluate them in light of empirical findings in three key domains, namely, human judgment, strategies of information processing, and memory. Throughout, we emphasize the influence of feelings on cognitive processes; the reverse influence of cognition on emotion is Three general approaches to the role of feelings in human cognition focus on the experiential, cognitive, and somatic components of feelings, respectively. The first approach emphasizes the experiential quality of feelings and addresses their informational functions. A second approach emphasizes the thoughts that accompany feelings, whereas a third approach emphasizes hard-wired processes, focusing on the somatic components of affective states. Central to the experiential approach is the assumption that feelings can serve as a source of information in their own right. This assumption is consistent with traditional theorizing on emotions and has been fruitfully extended to other subjective experiences. Social psychologists often subsume moods and emotions under the generic term affect. This term, however, can also refer simply to valence-the positive and negative aspect of things. All emotions are affective, but not all affective things are emotions. Emotions arise in response to ongoing, implicit appraisals of situations with respect to positive or negative implications for one's goals and concerns (e. have an identifiable referent (what the emotion is "about"), a sharp rise time, limited duration, and often high intensity. Emotion researchers commonly assume that "emotions exist for the Feelings-2 sake of signaling states of the world that have to be responded to, or that no longer need response and action" (Frijda, 1988, p. 354). What exactly emotions signal can be derived from their underlying appraisal patterns. Sadness, for example, signals a loss or lack of reward that is not attributed to the causal action of another agent; when it is attributed to the causal action of another agent, it gives rise to anger. Accordingly, sadness and …
Sexually Explicit Internet Material and Adolescents’ Sexual Performance Orientation: The Mediating Roles of Enjoyment and Perceived Utility

ABSTRACT Little is known about how exposure to sexually explicit Internet material (SEIM) relates to a performance-focused orientation toward sex. Based on a three-wave panel study among adolescents (N = 1,022), we found that watching SEIM predicted a sexual performance orientation from Wave (W) 2 to W3, but not from W1 to W2. A sexual performance orientation at W2 predicted adolescents’ exposure to SEIM at W3. The relationship between exposure to SEIM and a sexual performance orientation was explained by a two-step mediation model. The more adolescents were exposed to SEIM at W1, the more they enjoyed consuming this content at W2. In turn, enjoyment of SEIM (W2) predicted adolescents’ perceived utility of SEIM (W2). This increased perceived utility at W2 predicted a more intense performance orientation towards SEIM at W3. Within this 2-step model, we also found full support for a reciprocal relationship between using SEIM (W1/W2/W3) and enjoyment of SEIM (W1/W2/W3) and partial support for a reciprocal relationship between sexual performance orientation (W2) and perceived utility of SEIM (W3).
Synchrotron Self-Compton Model for Rapid Nonthermal Flares in Blazars with Frequency-dependent Time Lags

We model rapid variability of multifrequency emission from blazars occurring across the electromagnetic spectrum (from radio to gamma rays). Lower energy emission is produced by the synchrotron mechanism, whereas higher energy emission is due to inverse Compton scattering of the synchrotron emission. We take into account energy stratification established by particle acceleration at shock fronts and energy losses due to synchrotron emission. We also consider the effect of light-travel delays for the synchrotron emission that supplies the seed photons for inverse Compton scattering. The production of a flare is caused by the collision between a relativistic shock wave and a stationary feature in the jet (e.g., a Mach disk). The collision leads to the formation of forward and reverse shocks, which confine two contiguous emission regions resulting in complex profiles of simulated flares. Simulations of multifrequency flares indicate that relative delays between the inverse Compton flares and their synchrotron counterparts are dominated by energy stratification and geometry of the emitting regions, resulting in both negative and positive time delays depending on the frequency of observation. Light-travel effects of the seed photons may lead to a noticeable delay of the inverse Compton emission with respect to synchrotron variability if the line of sight is almost perfectly aligned with the jet. We apply the model to a flare in 3C 273 and derive the properties of shocked plasma responsible for the flare. We show that the pronounced negative time delay between the X-ray and IR light curves (X-rays peak after the maximum in the synchrotron emission) can be accounted for if both forward and reverse shocks are considered.
Rigorous Mathematical Thinking Approach to Enhance Students’ Mathematical Creative and Critical Thinking Abilities

The ability of mathematical creative and critical thinking are two abilities that need to be developed in the learning of mathematics. Therefore, efforts need to be made in the design of learning that is capable of developing both capabilities. The purpose of this research is to examine the mathematical creative and critical thinking ability of students who get rigorous mathematical thinking (RMT) approach and students who get expository approach. This research was quasi experiment with control group pretest-posttest design. The population were all of students grade 11th in one of the senior high school in Bandung. The result showed that: the achievement of mathematical creative and critical thinking abilities of student who obtain RMT is better than students who obtain expository approach. The use of Psychological tools and mediation with criteria of intentionality, reciprocity, and mediated of meaning on RMT helps students in developing condition in critical and creative processes. This achievement contributes to the development of integrated learning design on students’ critical and creative thinking processes.
Fatty Acids in Membranes as Homeostatic, Metabolic and Nutritional Biomarkers: Recent Advancements in Analytics and Diagnostics

Fatty acids, as structural components of membranes and inflammation/anti-inflammatory mediators, have well-known protective and regulatory effects. They are studied as biomarkers of pathological conditions, as well as saturated and unsaturated hydrophobic moieties in membrane phospholipids that contribute to homeostasis and physiological functions. Lifestyle, nutrition, metabolism and stress—with an excess of radical and oxidative processes—cause fatty acid changes that are examined in the human body using blood lipids. Fatty acid-based membrane lipidomics represents a powerful diagnostic tool for assessing the quantity and quality of fatty acid constituents and also for the follow-up of the membrane fatty acid remodeling that is associated with different physiological and pathological conditions. This review focuses on fatty acid biomarkers with two examples of recent lipidomic research and health applications: (i) monounsaturated fatty acids and the analytical challenge offered by hexadecenoic fatty acids (C16:1); and (ii) the cohort of 10 fatty acids in phospholipids of red blood cell membranes and its connections to metabolic and nutritional status in healthy and diseased subjects.
OGLE 2004–BLG–254: a K3 III Galactic bulge giant spatially resolved by a single microlens

Aims. We present an analysis of OGLE 2004-BLG-254, a high-magnification (A? 60) and relatively short duration (t_E? 13.2 days) microlensing event in which the source star, a Bulge K-giant, has been spatially resolved by a point-like lens. We seek to determine the lens and source distance, and provide a measurement of the linear limb-darkening coefficients of the source star in the I and R bands. We discuss the derived values of the latter and compare them to the classical theoretical laws, and furthermore examine the cases of already published microlensed GK-giants limb-darkening measurements. Methods: . We have obtained dense photometric coverage of the event light curve with OGLE and PLANET telescopes, as well as a high signal-to-noise ratio spectrum taken while the source was still magnified by A ? 20, using the UVES/VLT spectrograph. We have performed a modelling of the light curve, including finite source and parallax effects, and have combined spectroscopic and photometric analysis to infer the source distance. A Galactic model for the mass and velocity distribution of the stars has been used to estimate the lens distance. Results: . From the spectrum analysis and calibrated color-magnitude of the event target, we found that the source was a K3 III Bulge giant, situated at the far end of the Bulge. From modelling the light curve, we have derived an angular size of the Einstein ring ? _E? 114 ? as, and a relative lens-source proper motion ? = ? _E/t_E? 3.1 mas/yr. We could also measure the angular size of the source, ? _*? 4.5 ? as, whereas given the short duration of the event, no significant constraint could be obtained from parallax effects. A Galactic model based on the modelling of the light curve then provides us with an estimate of the lens distance, mass and velocity as D_L? 9.6 kpc, M? 0.11 M? and v ? 145~km s-1 (at the lens distance) respectively. Our dense coverage of this event allows us to measure limb darkening of the source star in the I and R bands. We also compare previous measurements of linear limb-darkening coefficients involving GK-giant stars with predictions from ATLAS atmosphere models. We discuss the case of K-giants and find a disagreement between limb-darkening measurements and model predictions, which may be caused by the inadequacy of the linear limb-darkening law.
Loss functions for estimation of extrema with an application to disease mapping

It is often of interest to find the maximum or near maxima among a set of vector‐valued parameters in a statistical model; in the case of disease mapping, for example, these correspond to relative‐risk “hotspots” where public‐health intervention may be needed. The general problem is one of estimating nonlinear functions of the ensemble of relative risks, but biased estimates result if posterior means are simply substituted into these nonlinear functions. The authors obtain better estimates of extrema from a new, weighted ranks squared error loss function. The derivation of these Bayes estimators assumes a hidden‐Markov random‐field model for relative risks, and their behaviour is illustrated with real and simulated data.
Assessment of Morphological and Functional Changes in Organs of Rats after Intramuscular Introduction of Iron Nanoparticles and Their Agglomerates

The research was performed on male Wistar rats based on assumptions that new microelement preparations containing metal nanoparticles and their agglomerates had potential. Morphological and functional changes in tissues in the injection site and dynamics of chemical element metabolism (25 indicators) in body were assessed after repeated intramuscular injections (total, 7) with preparation containing agglomerate of iron nanoparticles. As a result, iron depot was formed in myosymplasts of injection sites. The quantity of muscle fibers having positive Perls' stain increased with increasing number of injections. However, the concentration of the most chemical elements and iron significantly decreased in the whole skeletal muscle system (injection sites are not included). Consequently, it increased up to the control level after the sixth and the seventh injections. Among the studied organs (liver, kidneys, and spleen), Caspase-3 expression was revealed only in spleen. The expression had a direct dependence on the number of injections. Processes of iron elimination from preparation containing nanoparticles and their agglomerates had different intensity.
Evaluation of Apolipoprotein A1 and Posttranslationally Modified Forms of Transthyretin as Biomarkers for Ovarian Cancer Detection in an Independent Study Population

Background: Although overall 5-year survival rates for ovarian cancer are poor (10-30%), stage I/IIa patients have a 95% 5-year survival. New biomarkers that improve the diagnostic performance of existing tumor markers are critically needed. A previous study by Zhang et al. reported identification and validation of three biomarkers using proteomic profiling that together improved early-stage ovarian cancer detection. Methods: To evaluate these markers in an independent study population, postdiagnostic/pretreatment serum samples were collected from women hospitalized at the Mayo Clinic from 1980 to 1989 as part of the National Cancer Institute Immunodiagnostic Serum Bank. Sera from 42 women with ovarian cancer, 65 with benign tumors, and 76 with digestive diseases were included in this study. Levels of various posttranslationally forms of transthyretin and apolipoprotein A1 were measured in addition to CA125. Results: Mean levels of five of the six forms of transthyretin were significantly lower in cases than in controls. The specificity of a model including transthyretin and apolipoprotein A1 alone was high [96.5%; 95% confidence interval (95% CI), 91.9-98.8%] but sensitivity was low (52.4%; 95% CI, 36.4-68.0%). A class prediction algorithm using all seven markers, CA125, and age maintained high specificity (94.3%; 95% CI, 89.1-97.5%) but had higher sensitivity (78.6%; 95% CI, 63.2-89.7%). Conclusions: We were able to replicate the findings reported by Zhang et al. in an independently conducted blinded study. These results provide some evidence that including age of patient and these markers in a model may improve specificity, especially when CA125 levels are ≥35 units/mL. Influences of sample handling, subject characteristics, and other covariates on biomarker levels require further consideration in discovery and replication or validation studies.

Communication from above and below: Media, Protest and Democracy

ABSTRACT Since the end of apartheid, there has been a steady rise in community protests in South Africa. Many of these protests – often cumulatively grouped under the rubric of 'service delivery protests' are not only about the delivery of basic services, but equally about the closing down of democratic/institutional space and process when communities try to raise issues related to services and corruption. If protests are a way for the poor and the marginal to let their voices be heard, these protests should be seen as a form of communication from below with the aim of attaining greater social transformation and inclusion for those sections of society who still feel excluded from the democratic public sphere more than two decades after the arrival of formal democracy in South Africa. The coverage of these protests that the mainstream media provides, the way they are framed and the discourses constructed around them, can be considered communication from above. This paper investigates both these perspectives – from above and below – on community protests, through a three-fold methodology: a quantitative content analysis of print media coverage of community protests; qualitative in-depth interviews with journalists; and qualitative interviews with activists who were involved in the protests.
Maternal Age at Delivery Is Associated with an Epigenetic Signature in Both Newborns and Adults

Offspring of older mothers are at increased risk of adverse birth outcomes, childhood cancers, type 1 diabetes, and neurodevelopmental disorders. The underlying biologic mechanisms for most of these associations remain obscure. One possibility is that maternal aging may produce lasting changes in the epigenetic features of a child’s DNA. To test this, we explored the association of mothers’ age at pregnancy with methylation in her offspring, using blood samples from 890 Norwegian newborns and measuring DNA methylation at more than 450,000 CpG sites across the genome. We examined replication of a maternal-age finding in an independent group of 1062 Norwegian newborns, and then in 200 US middle-aged women. Older maternal age was significantly associated with reduced methylation at four adjacent CpGs near the 2nd exon of KLHL35 in newborns (p-values ranging from 3x10-6 to 8x10-7). These associations were replicated in the independent set of newborns, and replicated again in women 40 to 60 years after their birth. This study provides the first example of parental age permanently affecting the epigenetic profile of offspring. While the specific functions of the affected gene are unknown, this finding opens the possibility that a mother’s age at pregnancy could affect her child’s health through epigenetic mechanisms.
Prior Selection for Vector Autoregressions

Abstract Vector autoregressions (VARs) are flexible time series models that can capture complex dynamic interrelationships among macroeconomic variables. However, their dense parameterization leads to unstable inference and inaccurate out-of-sample forecasts, particularly for models with many variables. A solution to this problem is to use informative priors in order to shrink the richly parameterized unrestricted model toward a parsimonious naıve benchmark, and thus reduce estimation uncertainty. This paper studies the optimal choice of the informativeness of these priors, which we treat as additional parameters, in the spirit of hierarchical modeling. This approach, theoretically grounded and easy to implement, greatly reduces the number and importance of subjective choices in the setting of the prior. Moreover, it performs very well in terms of both out-of-sample forecasting—as well as factor models—and accuracy in the estimation of impulse response functions.
