Social Class Predicts Generalized Trust But Only in Wealthy Societies

This research examined the relationship between social class and generalized trust, or a belief that others have a benign intention in social interactions, in a diverse set of societies represented in the World Values Survey. The strength of the relationship varied significantly across societies: Although social class was a positive predictor of generalized trust in wealthy countries, as reported in past research, among less wealthy countries social class was uncorrelated with trust. These results indicate that resources available to individuals of high social class may make a trusting belief more rewarding; nevertheless, in less wealthy societies, the socio-political-economic infrastructure that supports generalized trust is unavailable, and therefore even individuals of high social class are reluctant to trust others. This finding extends prior theorizing on trust in finding the interactive relationship between an individual-level factor and a society-level factor in shaping individuals’ inclination toward trust.
WordNet improves text document clustering

Text document clustering plays an important role in providing intuitive navigation and browsing mechanisms by organizing large amounts of information into a small number of meaningful clusters. The bag of words representation used for these clustering methods is often unsatisfactory as it ignores relationships between important terms that do not co-occur literally. In order to deal with the problem, we integrate background knowledge — in our application Wordnet — into the process of clustering text documents. We cluster the documents by a standard partitional algorithm. Our experimental evaluation on Reuters newsfeeds compares clustering results with pre-categorizations of news. In the experiments, improvements of results by background knowledge compared to the baseline can be shown for many interesting tasks.
Some theoretical results concerning O3‐NOx‐VOC chemistry and NOx‐VOC indicators

[1] A series of model results is shown pertaining to ozone, reactive nitrogen (NOy), and peroxides in polluted regions. The results focus on ratios such as O3/NOy and H2O2/HNO3 that have been proposed as indicators for O3-NOx-VOC sensitivity. These ratios are shown to correlate with predicted NOx-VOC sensitivity for a variety of zero-dimensional (0-D) and 3-D models, but the correlation varies in situations ranging from relatively clean to highly polluted. The previously identified NOx-VOC transition values for indicators appear to be valid for moderately polluted conditions with 80–150 ppb O3. Changes in indicator behavior are linked to odd hydrogen chemistry and in particular to changes in the ratio of O3 to primary radical production. Changes in indicator behavior are also correlated with the values of a test ratio, O3/(2H2O2+NOz) which can be evaluated against measurements. Ratios of the form ΔO3/ΔNOy, representing differences relative to background values, are proposed for analyzing NOx-VOC sensitivity in individual urban plumes. Comparisons are made to extent-of-reaction parameters, which have been proposed for evaluating NOx-VOC sensitivity.
The acquisition and development of language by bilingual children

ABSTRACT Analysing the gradual learning process through which a child becomes bilingual from early infancy, three stages can be distinguished: (1) the child has one lexical system which includes words from both languages; (2) the child distinguishes two different lexicons but applies the same syntactic rules to both languages; (3) the child has two linguistic codes, differentiated both in lexicon and in syntax, but each language is exclusively associated with the person using that language. Only at the end of this stage, when the tendency to categorize people in terms of their language decreases, can one say that a child is truly bilingual.
Taxometric Analysis: II. Detecting Taxonicity Using Covariance of Two Quantitative Indicators in Successive Intervals of a Third Indicator (Maxcov Procedure)

Given three quantitative indicators of a conjectured latent taxon, a statistical function defined as the covariance of two indicators (designated for the procedure as the “output” indicators) computed within successive intervals along the third (designated as “input”) indicator reveals whether the latent structure of the data is taxonic or not. If it is taxonic, latent parameters (base rate, hit rates, complement and taxon means) can be estimated, the latent distributions drawn, and subjects assigned to the taxon or the complement group. Several consistency tests are described. MAXCOV (MAXimum COVariance) is one of a related family of taxometric procedures in Meehl's Coherent Cut Kinetics Method.
Risk for Psychiatric Disorder Among Immigrants and Their US-Born Descendants: Evidence From the National Comorbidity Survey Replication

Although previous research has consistently documented that immigrants to the United States have better mental health than US natives, little is known about why this difference occurs. DSM-IV anxiety, mood, impulse control, and substance use disorders were assessed in a nationally representative survey of the US household population, the National Comorbidity Survey Replication. Differences in risk for disorder between immigrants (N = 299) and 5124 natives (N = 5124) were examined using discrete time survival models. Differences were estimated by generation, age of immigration, and duration of residence in the United States. Immigrants had lower lifetime risk of disorder than natives (OR = 0.7; 95% CI, 0.5–0.9). Risk was equally large for natives who were children of immigrants as for natives of subsequent generations. For mood and impulse control disorders, risk equal to that of natives was also found among immigrants who arrived in the United States as children (12 years of age or younger). Immigrants had lower risk than natives prior to arrival in the United States, but there was a trend toward equalization of risk with longer duration of residence in the United States. Differences in risk for disorder emerge within a single generation following immigration, consistent with a strong effect of environmental factors on changes in risk among immigrant populations. This pattern is consistent with either of two causal processes, one involving early socialization in the United States and the other involving postmigration experiences among immigrants who arrive in the United States as adults.
The Criminology of Downsizing

It is worth pausing a moment to let the enormity and swiftness of today’s changes sink in. A few years ago, around 2011, even as correctional populations had just started their ever-so-slight decline, most observers believed that the underlying political dynamics of incarceration policy remained as they had been for almost a half-century. The main elements of the politics of penal policy have not been a mystery. First, it has been thought that political leaders need to anchor proposals for crime policy on a foundation of deterrence and incapacitation. Second, prisons must remain central to the agenda of public protection. And third, to succeed, a politician must avoid at all costs being branded as “soft on crime. ” That the politics of crime lead inexorably to more prisons has been taken as a kind of law of nature, a gravitational pull that makes meaningful prison reform in the United States a nonstarter. So it has come as an understandable shock to see the avalanche of news running contrary to this received wisdom. The people we have elected to office are daily announcing proposals they think will reduce the number of people behind bars, and the people who want to take their place are pushing and even more aggressive agenda, sometimes calling for an end to “mass incarceration. ” Left-right public interest coalitions have formed to engage a national agenda to reduce the prion population. Major private sources have invested substantial capital in this work. The emerging political wind is matched by repeated editorials, news stories, and documentaries that now make “reducing prison populations” a mainstream public idea.
Patients' attitudes to wearing of gloves by dentists in Nigeria.

OBJECTIVE To evaluate patient's attitudes to the use of gloves by dentists. DESIGN This consisted of a four-item questionnaire administered to 445 consecutive patients attending our dental clinic. SETTING . Obafemi Awolowo University Teaching Hospitals' Complex, Ile-Ife, Nigeria. SUBJECTS Four hundred and forty five patients above the age of fifteen years attending the dental clinic for the first time. RESULTS Majority of the patients were in the 20-30 year age group and over 93% had formal education. Most of the respondents (88.8%) stated that glove wearing was essential and over 63% considered that glove wearing protected both the operator and the patient. Whilst about one-third of respondents would attend for treatment when gloves were not worn, 81.3% felt that gloves should be changed after each patient. There were statistically significant differences (p<0.05) in responses in relation to age-groups and educational attainment, however no sex differences (p>0.05) were reported. CONCLUSION This survey showed a high level of awareness by patients on the use of gloves by dentists. It also found that age-groups and levels of educational attainment influenced patients attitude to glove use.
Original Investigation

Rationale Rats will lever press to deliver nanolitre quantities of nicotine or the muscarinic agonist carbachol directly into the ventral tegmental area (VTA). The purpose of these experiments was to investigate further the characteristics of nicotine self-administration directly into the VTA. Objectives This study aimed to confirm previous data relating to intra-VTA self-administration of nicotine and carbachol and then test two hypotheses: (a) that pre-sensitisation of nicotinic receptors is needed for robust intra-VTA self administration and (b) that rats will lever press for intra-VTA nicotine if pre-trained to associate lever pressing with a rewarding outcome. Methods Rats were equipped with cannulae aimed at posterior VTA and allowed five sessions to self-administer nicotine or carbachol. In different experiments, rats were either pre-sensitised to nicotine by subcutaneous (s.c.) injections or pre-trained to lever press for food and a simultaneous conditioned stimulus light. Results We confirmed that carbachol had strong activating effects when self-administered into the VTA; selective responding for nicotine developed over five sessions by reduction in the amount of pressing on an inactive lever. Prior sensitisation did not improve responding for intra-VTA nicotine but training rats to lever press before putting them on the drug regime did potentiate pressing. Conclusions The action of nicotine in the VTA might be better considered as reinforcement enhancing and that its intrinsic rewarding property here is at best weak. Identification of the VTA as a target for the reinforcement enhancing effects of nicotine is compatible with the reinforcement-related functions of VTA dopamine neurons and their cholinergic inputs.
Dobutamine magnetic resonance imaging as a predictor of myocardial functional recovery after revascularisation

OBJECTIVE To assess the use of dobutamine magnetic resonance imaging (MRI) as a preoperative predictor of myocardial functional recovery after revascularisation, comparing wall motion and radial wall thickening analyses by observer and semi-automated edge detection. PATIENTS 25 men with multivessel coronary disease and resting wall motion abnormalities were studied with preoperative rest and stress MRI. MAIN OUTCOME MEASURES Observer analysis for radial wall thickening was compared with a normal range, while wall motion analysis used a standard four point scale. Semi-automated analysis was performed using an edge detection algorithm. Segments displaying either improved or worsened thickening or motion with dobutamine were considered viable. Postoperative rest images were performed 3–6 months after coronary artery bypass grafting (CABG) for comparison. RESULTS For observer analysis the values for sensitivity and specificity were 50% and 72% for wall motion, with respective values of 50% and 68% for thickening. With semi-automated edge detection the figures for motion were 60% and 73%, with corresponding values of 79% and 58% for thickening. Combining thickening and motion for the semi-automated method to describe any change in segmental function yielded a sensitivity of 71% and specificity of 70%. CONCLUSIONS Dobutamine MRI is a reasonably good predictor of myocardial functional recovery after CABG. The use of semi-automated edge detection analysis improved results.
AT2 receptor stimulation increases aortic cyclic GMP in SHRSP by a kinin-dependent mechanism.

In the present study we tested the hypothesis whether an angiotensin AT2 receptor-mediated stimulation of the bradykinin (BK)/nitric oxide (NO) system can account for the effects of AT1 receptor antagonism on aortic cGMP described previously in SHRSP. Adult SHRSP were treated for 4 hours with angiotensin II (ANG II) (30 ng/kg per min IV) or vehicle (0.9% NaCl I.V.). Animals were pretreated with vehicle, losartan (100 mg/kg P.O.), PD 123319 (30 mg/kg I.V.), losartan plus PD 123319, icatibant (500 microg/kg I.V.), N(G)-nitro-L-arginine methyl ester (L-NAME; 1 mg/kg I.V.), or minoxidil (3 mg/kg I.V.). Mean arterial blood pressure (MAP) was continuously monitored over the 4-hour experimental period, and plasma ANG II and aortic cGMP were measured by RIA at the end of the study. ANG II infusion over 4 hours raised MAP by about 20 mm Hg. Losartan alone or losartan plus ANG II as well as minoxidil plus ANG II markedly reduced blood pressure when compared to vehicle-treated or ANG II-treated animals, respectively. Plasma levels of ANG II were increased 2-fold by ANG II infusion alone or by ANG II in combination with icatibant, L-NAME, or minoxidil. The increase in plasma ANG II levels was even more pronounced after losartan treatment. Aortic cGMP content was significantly increased by ANG II, losartan, losartan plus ANG II, and minoxidil plus ANG II by 60%, 45%, 68%, and 52%, respectively (P<.05). The effects of ANG II and of losartan plus ANG II on aortic cGMP content were both blocked by cotreatment with the AT2 receptor antagonist PD 123319. Icatibant and L-NAME abolished the effects of ANG II on aortic cGMP. Our results demonstrate the following: (1) ANG II increases aortic cGMP by an AT2 receptor-mediated action because the effect could be prevented by an AT2 receptor antagonist; (2) the effect of ANG II was not secondary to blood pressure increase because it remained under reduction of MAP with minoxidil; (3) losartan increased aortic cGMP most likely by increasing plasma ANG II levels with a subsequent stimulation of AT2 receptors; and (4) the effects of AT2 receptor stimulation are mediated by BK and, subsequently, NO because they were abolished by B2 receptor blockade as well as by NO synthase inhibition.
An investigation of role salience and linkages to work-family conflict

An Investigation of Role Salience and Linkages to Work-Family Conflict. (May 2011) Tomika Wilson Greer, B.S., North Carolina State University; M.Ed., Texas Tech University Chair of Advisory Committee: Dr. Toby Marshall Egan This dissertation contains reports of three separate studies in which the connections between work role salience, family role salience, stereotype threat, and work-family conflict were explored. In the first study, findings from a systematic review of the role salience literature were reported. Following a search of four Human Resource Development (HRD) journals, the PsycINFO database, and the Academic Search Complete database, 69 articles and papers were identified for inclusion in the literature review. The literature mostly pertained to career development, with a notable emphasis on life-span, life-space theory. Though, very little of the research in the sample of literature pertained specifically to how individuals negotiate their lives as they occupy multiple life roles. In the second study, meta-analytic techniques were used to identify the nature of the relationships between work role salience, family role salience, and work-family conflict. Hypothesized relationships were based on conservation of resources theory. Data were collected from fourteen papers and articles to test the hypothesized
Microsatellite instability analysis in typical and progressed mantle cell lymphoma and B-cell chronic lymphocytic leukemia.

BACKGROUND AND OBJECTIVES Microsatellite instability (MSI) is characterized by tumor-associated alterations in the germline size of microsatellite repeats caused by a reduced efficacy of the DNA mismatch repair machinery. The aim of this study was to investigate the presence of MSI in a number of cases of indolent and aggressive mantle cell lymphoma (MCL) and B-cell chronic lymphocytic leukemia (B-CLL) to determine its possible role in the initial development and progression of these disorders. DESIGN AND METHODS We examined the presence of MSI in 28 B-CLL, 24 typical and 4 transformed B-CLL (Richter's syndrome) and 29 MCL, 19 typical and 10 blastoid variants by using a panel of 10 microsatellite markers and analyzed them using an AbiPrism 310 DNA sequencer. Fisher's exact test was used to compare categorical variables and Mann-Whitney's U-test for continuous variables. RESULTS MSI alterations were not observed in any case of MCL or Richter's syndrome and in only three (13%) patients with typical B-CLL. Two of these patients also had loss of heterozygosity in one of the 10 sites examined. These patients presented with a more advanced stage, diffuse bone marrow involvement, and poorer performance status than patients without these alterations. INTERPRETATION AND CONCLUSIONS These findings indicate that MSI is not involved in the pathogenesis or progression of B-CLL and MCL but may appear in a small subset of patients with advanced B-CLL.
Age-related effects on speech production: A review

In discourse, older adults tend to be more verbose and more disfluent than young adults, especially when the task is difficult and when it places few constraints on the content of the utterance. This may be due to (a) language-specific deficits in planning the content and syntactic structure of utterances or in selecting and retrieving words from the mental lexicon, (b) a general deficit in inhibiting irrelevant information, or (c) the selection of a specific speech style. The possibility that older adults have a deficit in lexical retrieval is supported by the results of picture naming studies, in which older adults have been found to name objects less accurately and more slowly than young adults, and by the results of definition naming studies, in which older adults have been found to experience more tip-of-the-tongue (TOT) states than young adults. The available evidence suggests that these age differences are largely due to weakening of the connections linking word lemmas to phonological word forms, though adults above 70 years of age may have an additional deficit in lemma selection.
Social embeddedness in a harmonized Europe: the social networks of European migrants with a native partner in Belgium and the Netherlands

Although intra-European migration is often considered relatively easy to realize given European citizens' right to freedom of movement, settlement in another European country can still be experienced as socially disruptive. Insights in the insertion processes of European migrants, nevertheless, remain rather scarce. In this study, we analyse the social networks of European nationals with a native partner in Belgium and the Netherlands. The analysis is based on survey data from the EUMARR project (n = 576). First, we study the size and composition of European migrants' local family and friendship networks, and the frequency of contact with these networks. Second, we connect intra-EU movers' insertion routes to investments in transnational networks in their home country. The results reveal how size, composition and contact with the local and transnational network change over time. Children help to maintain contact with both the local and transnational family network and form a bridge for parents to meet own friends in the host country. Moreover, having own friends and own family around matters for contact frequency with the local networks.
Distributed and Parallel Algorithms for Set Cover Problems with Small Neighborhood Covers

In this paper, we study a class of set cover problems that satisfy a special property which we call the {\em small neighborhood cover} property. This class encompasses several well-studied problems including vertex cover, interval cover, bag interval cover and tree cover. We design unified distributed and parallel algorithms that can handle any set cover problem falling under the above framework and yield constant factor approximations. These algorithms run in polylogarithmic communication rounds in the distributed setting and are in NC, in the parallel setting.
Reconciling Normative and Behavioural Economics

The aim of this thesis is to address from a methodological, philosophical and theoretical perspective the problem of how to reconcile normative and behavioural economics — the “reconciliation problem”. The first part develops a methodological assessment of behavioural welfare economics (and more specifically of libertarian paternalism), which currently constitutes the most accepted approach to deal with the reconciliation problem. We argue that behavioural welfare economics is in the direct continuation of neoclassical welfare economics, and that its conception of individual behaviour is tightly connected to Pareto’s reductionist model of the Homo economicus. It is assumed that an individual can be defined by “true” preferences — distinct from her revealed preferences — and that those preferences are consistent and context-independent. The satisfaction of those true preferences is taken as the normative criterion. The existence of true preferences requires accepting that people have access to a latent mode of reasoning able to generate consistent and context-independent preferences, and to treat individual decision-making as if it was the result of an optimisation problem faced by an inner rational agent trapped in an outer psychological shell. We argue on the contrary that we cannot define unambiguously such true preferences. We then argue that the normative challenge raised by behavioural economics is that individuals may lack of autonomy: rather than focusing on the satisfaction of one’s preferences, we argue that what matters is the ability to choose one’s own preferences. Since we suggest that the difficulties of behavioural welfare economics are related to its commitment to an implausible model of individual preferences, we provide in the second part of the thesis a model of preferences compatible with our methodological analysis: we take Bacharach’s variable frame theory as the primitive of our analysis, and build a model of endogenous preferences, in which individuals can choose to some extent their own preferences. The main contributions of this model are that (i) it does not require the existence of latent true preferences, and (ii) the individuals are allowed to team reason. We assume that collective preferences are strategically chosen, and show that team reasoners tend to be aggressive (cooperative) with other teams in submodular (supermodular) games. We finally show that team reasoning can be empirically justified as an ecologically rational heuristic.
