Transnational Tense: Immigration and Inequality in American Housing Markets

Spatial assimilation theory, the traditional framework for analysing urban immigration and housing, was deeply shaped by the historical–geographic contingencies of American urbanism in the 1950s and 1960s. Yet the most recent and forceful challenge to assimilationist research—transnational urbanism—is also influenced by distinctive contemporary circumstances and epistemological priorities, creating a tense and unproductive dichotomy. We contend that such apparently fundamental theoretical disputes are at least partially resolved through methodological pluralism. Understanding continuity and change in immigrant settlement and housing patterns requires that we draw on the distinct, complementary merits of transnational urbanist and spatial assimilation models—while also recognising the features of American urban development and race relations that create powerful incentives shaping the spatial trajectories of immigrant upward mobility. We evaluate these considerations through empirical case studies of the recent rise of home-ownership among Hmong immigrants in St Paul, Minnesota, and the interrelations between immigration and the intensified mortgage capitalisation of US housing markets.
Ciprofloxacin dry powder for inhalation in non-cystic fibrosis bronchiectasis: a phase II randomised study

This phase II, randomised, double-blind, multicentre study (NCT00930982) investigated the safety and efficacy of ciprofloxacin dry powder for inhalation (DPI) in patients with non-cystic fibrosis bronchiectasis. Adults who were culture positive for pre-defined potential respiratory pathogens (including Pseudomonas aeruginosa and Haemophilus influenzae) were randomised to ciprofloxacin DPI 32.5 mg or placebo administered twice daily for 28 days (with 56 days of follow-up). Bacterial density in sputum (primary end-point), pulmonary function tests, health-related quality of life and safety were monitored throughout the study. 60 subjects received ciprofloxacin DPI 32.5 mg and 64 received placebo. Subjects on ciprofloxacin DPI had a significant reduction (p<0.001) in total sputum bacterial load at the end of treatment (-3.62 log10 CFU·g−1 (range -9.78–5.02 log10 CFU·g−1)) compared with placebo (-0.27 log10 CFU·g−1 (range -7.96–5.25 log10 CFU·g−1)); the counts increased thereafter. In the ciprofloxacin DPI group, 14 (35%) out of 40 subjects reported pathogen eradication at end of treatment versus four (8%) out of 49 in the placebo group (p=0.001). No abnormal safety results were reported and rates of bronchospasm were low. Ciprofloxacin DPI 32.5 mg twice daily for 28 days was well tolerated and achieved significant reductions in total bacterial load compared with placebo in subjects with non-cystic fibrosis bronchiectasis.
An attachment and behavioral systems perspective on social support

In this article we explain how attachment theory characterizes the seeking, receipt, and provision of social support. In the first section, we explain attachment theory's perspective on support-seeking (or attachment behavior) and support-provision (or caregiving behavior). In the second section, we discuss what has been learned about attachment-style differences in perceived support, seeking support, and providing support. In the third section, we consider the empirically documented psychological benefits of receiving support, which we summarize in terms of a broaden-and-build cycle of attachment security. Throughout the article we offer several avenues for future research that can advance our understanding of the cognitive-affective and neural mechanisms underlying social support and the psychological benefits of supportive experiences.
Microglomerular Synaptic Complexes in the Sky-Compass Network of the Honeybee Connect Parallel Pathways from the Anterior Optic Tubercle to the Central Complex

While the ability of honeybees to navigate relying on sky-compass information has been investigated in a large number of behavioral studies, the underlying neuronal system has so far received less attention. The sky-compass pathway has recently been described from its input region, the dorsal rim area (DRA) of the compound eye, to the anterior optic tubercle (AOTU). The aim of this study is to reveal the connection from the AOTU to the central complex (CX). For this purpose, we investigated the anatomy of large microglomerular synaptic complexes in the medial and lateral bulbs (MBUs/LBUs) of the lateral complex (LX). The synaptic complexes are formed by tubercle-lateral accessory lobe neuron 1 (TuLAL1) neurons of the AOTU and GABAergic tangential neurons of the central body’s (CB) lower division (TL neurons). Both TuLAL1 and TL neurons strongly resemble neurons forming these complexes in other insect species. We further investigated the ultrastructure of these synaptic complexes using transmission electron microscopy. We found that single large presynaptic terminals of TuLAL1 neurons enclose many small profiles (SPs) of TL neurons. The synaptic connections between these neurons are established by two types of synapses: divergent dyads and divergent tetrads. Our data support the assumption that these complexes are a highly conserved feature in the insect brain and play an important role in reliable signal transmission within the sky-compass pathway.
Ethical leadership and organizational citizenship behavior: The mediating roles of cognitive and affective trust

I proposed that trust mediates the relationship between ethical leadership and organizational citizenship behavior, which is classified into 2 types: organizationally directed (OCBO) and individually directed (OCBI). Participants comprised 104 supervisor-subordinate dyads employed in public-sector organizations in a city in eastern China. The results showed that ethical leadership had a significant main effect on both OCBO and OCBI. In addition, cognitive trust had no significant mediating effect on the relationships between ethical leadership and OCBO and ethical leadership and OCBI, but affective trust fully mediated these relationships. The contribution of the results, limitations in the study, and future directions for research are also discussed.
Biological Activity of an Intravenous Preparation of Human Vaccinia Immune Globulin in Mouse Models of Vaccinia Virus Infection

ABSTRACT The biological activity of a new intravenous (i.v.) preparation of human vaccinia immune globulin (VIGIV) was evaluated in two mouse models of vaccinia virus (VV) infection. In a mouse tail lesion model, female CD-1 mice were inoculated i.v. with 7 × 104 PFU of VV to produce >10 lesions per tail 8 days later. In a mouse lethality model, female severe combined immunodeficient (SCID) mice were inoculated i.v. with 3 × 104 PFU of VV to produce 100% mortality within 45 days. The ability of VIGIV to reduce tail lesion formation in CD-1 mice and mortality in SCID mice was determined by (i) pretreatment of a lethal VV dose with VIGIV prior to i.v. inoculation into SCID mice and (ii) i.v. administration of VIGIV to CD-1 and SCID mice the day before and up to 8 days after VV infection. VIGIV reduced the proportion of CD-1 mice with >10 tail lesions in a dose-related manner when VIGIV was given 1 day before and up to 1 day after VV inoculation. The pretreatment of VV with VIGIV prolonged survival and decreased mortality. VIGIV (100 and 400 mg/kg) prolonged survival when given up to 4 days after VV inoculation, and the 400-mg/kg dose reduced the mortality rate by 80% when given the day before or immediately after VV inoculation. The biological activity of VIGIV was demonstrated in both the immunocompetent and immunocompromised murine models. The timing of treatment relative to VV inoculation appeared to be important for the demonstration of VIGIV's biological activity.
Family Function of the Families Consisting of Asian Immigrant Women Living in South Korea

Marriages between Korean men and immigrant women from elsewhere in Asia have increased rapidly during recent years. The aim of this study was to analyze the relationship within families consisting of immigrant women and to identify the relevant factors. The study subjects were 62 Asian immigrant women married to South Korean men living in South Korea. In a baseline study in August 2008, the socioeconomic factors and family APGAR (adaptation, partnership, growth, affection, and resolve) scores were measured. Family APGAR has been widely used to study the relationship of family function and health problems in the busy clinician’s office. A 3-year follow-up study was then conducted in August 2011, and the results were compared with the baseline study results. Family APGAR scores were higher at the 3-year follow-up than those at baseline. Changes in family APGAR scores were found to be influenced by the birthplace, reported subjective ability to read Korean, and Center for Epidemiologic Studies–Depression Scale score.
Trends in socioeconomic mortality differentials in post‐war Norway: evidence and interpretations

The aim of the study was to describe changes in socioeconomic mortality differentials among adults in post-war Norway and to examine some selected interpretations. Three separate data sets were obtained. In each set census information on occupational class was linked to subsequent mortality during three five-year periods 1960-65 1970-75 and 1980-85. The analysis showed a general decline in mortality but an increase in the socioeconomic mortality differentials among men. (EXCERPT)
Prioritizing health system and disease burden factors: an evaluation of the net benefit of transferring health technology interventions to different districts in Zimbabwe

Introduction Health-care technologies (HCTs) play an important role in any country’s health-care system. Zimbabwe’s health-care system uses a lot of HCTs developed in other countries. However, a number of local factors have affected the absorption and use of these technologies. We therefore set out to test the hypothesis that the net benefit regression framework (NBRF) could be a helpful benefit testing model that enables assessment of intra-national variables in HCT transfer. Method We used an NBRF model to assess the benefits of transferring cost-effective technologies to different jurisdictions. We used the country’s 57 administrative districts to proxy different jurisdictions. For the dependent variable, we combined the cost and effectiveness ratios with the districts’ per capita health expenditure. The cost and effectiveness ratios were obtained from HIV/AIDS and malaria randomized controlled trials, which did either a prospective or retrospective cost-effectiveness analysis. The independent variables were district demographic and socioeconomic determinants of health. Results The study showed that intra-national variation resulted in different net benefits of the same health technology intervention if implemented in different districts in Zimbabwe. The study showed that population data, health data, infrastructure, demographic and health-seeking behavior had significant effects on the net margin benefit for the different districts. The net benefits also differed in terms of magnitude as a result of the local factors. Conclusion Net benefit testing using local data is a very useful tool for assessing the transferability and further adoption of HCTs developed elsewhere. However, adopting interventions with a positive net benefit should also not be an end in itself. Information on positive or negative net benefit could also be used to ascertain either the level of future savings that a technology can realize or the level of investment needed for the particular technology to become beneficial.
A Cultural Perspective on the Structure of Student Interest in Science

In this paper, we examine the nature of interest in science as represented in the Programme for International Student Assessment (PISA) 2006 data. We discuss the interconnections between measures of knowledge, affect, and value as components of interest in science. Working from a perspective acknowledging that many of the models of motivation represented in the literature have been developed in Western countries, we investigated whether the ways that knowledge, affect, and value combine in the structure of students’ interest in science might vary in line with historical and cultural traditions. Four countries were chosen to represent contrasting cultural values as defined in analyses of the World Values Surveys and the European Values Surveys—Colombia, Estonia, USA, and Sweden. Models are described showing variations in fit across the four countries. Efforts to increase the attractiveness of science to students should take heed of the fact that all models indicated a central role for enjoyment of science in the paths linking personal value, interest, and current science activities with intentions for future participation in science. Differences in the strength of the associations between science knowledge and interest in science support the proposition that the interconnections between knowledge, affect, and value need to be understood in relation to students’ broader historical and cultural context.
Attention Decreases Phase-Amplitude Coupling, Enhancing Stimulus Discriminability in Cortical Area MT

Local field potentials (LFPs) in cortex reflect synchronous fluctuations in the synaptic activity of local populations of neurons. The power of high frequency (>30 Hz) oscillations in LFPs is locked to the phase of low frequency (<30 Hz) oscillations, an effect known as phase-amplitude coupling (PAC). While PAC has been observed in a variety of cortical regions and animal models, its functional role particularly in primate visual cortex is largely unknown. Here, we document PAC for LFPs recorded from extra-striate area MT of macaque monkeys, an area specialized for the processing of visual motion. We further show that directing spatial attention into the receptive field of MT neurons decreases the coupling between the low frequency phase and high frequency power of LFPs. This attentional suppression of PAC increases neuronal discriminability for attended visual stimuli. Therefore, we hypothesize that visual cortex uses PAC to regulate inter-neuronal correlations and thereby enhances the coding of relevant stimuli.
Reducing Iron Loss in Interior PM Machines under Field-Weakening Conditions

Field-weakening in interior PM machines is performed by using negative rf-axis current to oppose the magnet flux and hence reduce the total fundamental rf-axis flux at high speeds. Due to the rotor saliency, the rf-axis current produces large amplitude harmonic airgap flux density components which can cause large harmonic stator iron losses. Reducing the magnet flux density reduces the required rf-axis stator mmf to oppose it and hence reduces the field-weakening iron losses. However reducing the magnet flux density also reduces the magnet torque and hence increases the stator current requirement, particularly at lower speeds. This paper examines this trade-off for an automotive integrated starter/alternator using a graphical interior PM machine parameter plane approach.
Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction analyses of mineral and organic matrix during heating of mother of pearl (nacre) from the shell of the mollusc Pinctada maxima.

Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction patterns were used to analyze the mineral structure and organic matrix composition and thermal behavior of the internal nacreous layer (mother of pearl or nacre) of the shell of the giant oyster Pinctada maxima. Nacre is a natural biomaterial with osteogenic properties. The mineral of nacre is calcium carbonate crystallized as aragonite and it is highly crystallized. The FT-IR spectra showed amide, amine, and carboxylic acid groups in the organic matrix of the whole (organic and mineral) nacreous layer, with the HCO(-)(3) groups possibly at the organic-mineral interface. The insoluble organic matrix remaining after decalcification contained amide, amine, and carboxylic groups. The heated aragonite mineral structure of nacre underwent two transformations (X-ray diffraction), aragonite to calcite at 300-400 degrees C, and calcite to calcium oxide (CaO) at 500-600 degrees C. The organic matrix of nacre was destroyed around 550-600 degrees C, the same temperature as the calcite to CaO transformation, revealing the great thermal stability of the organic matrix and the organic-mineral bonding. This could be an useful feature for the in vivo use of this natural biomaterial as an implant.
Laid Off, But Still Loyal: The Influence of Perceived Justice and Organizational Support

Research on layoff victims reports that interactional justice judgments influence important work‐related attitudes, such as organizational commitment. In this paper, we build on this emerging literature through an examination of the role that both interactional justice and organizational support have in explaining the organizational commitment of 147 layoff victims at a major manufacturing plant. The results of structural equation analyses supported our hypothesis that organizational support mediates the relationship between interactional justice and organizational commitment.
25-Hydroxyvitamin D3-1α-hydroxylase Expression in Normal and Malignant Human Colon

1,25-dihydroxyvitamin D3 has anti-mitotic, pro-differentiating, and pro-apoptotic activity in tumor cells. We demonstrated that the secosteroid can be synthesized and degraded not only in the kidney but also extrarenally in intestinal cells. Evaluation of 1,25-dihydroxyvitamin D3-synthesizing CYP27B1 hydroxylase mRNA (real-time PCR) and protein (immunoblotting, immunofluorescence) showed enhanced expression in high- to medium-differentiated human colon tumors compared with tumor-adjacent normal mucosa or with colon mucosa from non-cancer patients. In high-grade undifferentiated tumor areas expression was lost. Many cells co-expressed CYP27B1 and the vitamin D receptor. We suggest that autocrine/paracrine antimitotic activity of 1,25-dihydroxyvitamin D3 could prevent intestinal tumor formation and progression. (J Histochem Cytochem 52:985–989, 2004)
Augmented Responses to Vasoconstrictor Stimuli in Hypercholesterolemic and Atherosclerotic Monkeys

We examined effects of hypercholesterolemia and atherosclerosis on vasoconstrictor responses to norepinephrine and serotonin. Responses were compared in normal, atherosclerotic, and hypercholesterolemic but non-atherosclerotic cynomolgus monkeys. The hindlimb was per fused at constant flow so that changes in perfusion pressure indicated changes in vascular resistance. We measured the pressure gradient from the iliac to the dorsal pedal artery so that responses of the large artery segment could be determined. Serotonin decreased total hindlimb resistance in normal and hypercholesterolemic monkeys, but increased total resistance in athero sclerotic monkeys. There was a greater than 10-fold increase in constrictor responses of large arteries to serotonin in atherosclerotic monkeys, compared with normal and hypercholesterolemic monkeys. In contrast, we found that vasoconstrictor responses tc norepinephrine are normal in atherosclerotic monkeys and increased in hypercholesterolemic monkeys prior to development of atherosclerosis. Hypercholesterolemia augmented responses of small vessels to norepinephrine. We conclude that, during early stages of hypercholesterolemia in cynomolgus monkeys, vasocon strictor responses to norepinephrine are increased in small vessels. At a later stage, as atheroscle rosis develops, responses to norepinephrine return to normal, but vasoconstrictor effects of large arteries to serotonin are greatly potentiated.
An examination of gender role portrayals in television commercials in Romania: A gender of nations approach

This study examines gender role portrayals in Romanian television commercials. Results reveal both progressive and traditional gender role portrayals for both women and men reflecting a society and economy in a state of transition toward European Union membership. The study also involves a test of the concept of gender of nations using Hofstede's Masculinity Index (MAS). Extending a methodological approach first used by Milner and Collins (1998, 2000) gender role portrayals in Romanian commercials (moderate MAS) were compared with those appearing in Japanese (high MAS) and Swedish (low MAS) commercials. The results, which are consistent with predictions based on the relative MAS scores of the three nations, are discussed along with managerial implications.
Antecedents of Job Stress and Its Impact on Job Satisfaction

Achieving the pleasures of successful work place is an art of coping with stress. Job stress is a very substantial issue at work place in this new era of competence. So this research is significantly emphasized on causes and effects of job stress and analyze its impact upon job satisfaction. This study also identifies the root causes of job stress (like work overload, role ambiguity, role conflict) and their influence on employees wellbeing, behavior and contribution towards effectiveness. A questionnaire (scales consisting thirty two items) is developed to assess the relationship between job stress and job satisfaction on the basis of Regression and ANOVA analysis. The findings describe very significant results between the variables. There is a very significant positive correlation between work overload and job stress and same is true for role conflict and role ambiguity. The negative correlation is found between job stress and job satisfaction. All the instruments and scales are taken from the standard sources. The results of study can be beneficial for the wide range of organizations, institutions, companies and departments for the better understanding of behavior and wellbeing of the employee’s. Practical implications of results are also having a very significant importance for training concern organizations. This research suggests the direction for future recommendation on the relationship between job stress and organizational performance more concisely and briefly.
Fundamental research by means of laboratory experiments is essential for a better understanding of organizational justice

Abstract In this paper, it is argued that because the bulk of justice research has employed correlational research methods within real-life situations, we know quite a lot about the effects justice perceptions can have on people in organizations and other situations. Yet, this may have been achieved at the expense of thorough insights into the two most fundamental issues of organizational justice: why do people care about fairness and how are fairness judgments formed? It is proposed that the fundamentals of the why and how of organizational justice should be investigated by means of research methods that are best suited to study fundamental issues: laboratory experiments.
A game theoretic approach to expander-based compressive sensing

We consider the following expander-based compressive sensing (e-CS) problem: Given Φ ∈ ℝM×N (M &#60; N), which is the adjacency matrix of an expander graph, and a vector y ∈ ℝM, we seek to find a vector x* with at most k-nonzero entries such that equation whenever it exists (k ≪ N). Such problems are not only nonsmooth, barring naive convexified sparse recovery approaches, but also are NP-Hard in general. To handle the non-smoothness, we provide a saddle-point reformulation of the e-CS problem, and propose a novel approximation scheme, called the game-theoretic approximate matching estimator (GAME) algorithm. We then show that the restricted isometry property of expander matrices in the ℓ1-norm circumvents the intractability of e-CS in the worst case. GAME therefore finds a sparse approximation x̂ to optimal solution such that equation. We also propose a convex optimization approach to e-CS based on Nesterov smoothing, and discuss its (dis)advantages.
