Spousal relations and well‐being: A comparative analysis of Jewish and Arab dual‐earner families in Israel

The study examined differences in division of household tasks and spousal support among a sample of educated dual-earner families from two national groups in Israel: Jews (n = 116), and Arabs (n = 163). The contribution of the spousal interaction variables (household roles and spousal support) toward explaining two dimensions of psychological well-being (burnout and life satisfaction) was also examined. The research findings indicate that in general, the Arabs maintain a more traditional orientation toward gender roles than their Jewish counterparts. Arab men showed a greater tendency to perform outside tasks than their Jewish counterparts who participate more in domestic chores. By contrast, no differences were found between the two groups with regard to the mutual support provided by spouses. Gender role attitudes were found to be a key predictor of the two psychological well-being dimensions in both national groups. Regarding sex differences, men of both nationalities were more likely than women to report that they perform all types of household tasks. Concomitantly, the women reported higher levels of burnout, while no differences between the sexes were found with respect to life satisfaction. © 2003 Wiley Periodicals, Inc.
Validation of the CHORES: a measure of school-aged children's participation in household tasks

The CHORES (Children Helping Out: Responsibilities, Expectations, and Supports) is a clinical and research tool that measures school-aged children's participation in household tasks. Separate performance and assistance scores enable examination of changes in children's responsibilities for household tasks as they mature and the work of families to promote their participation. The Self-Care and Family-Care subscales afford study of cultural aspects of household tasks that may influence children's participation and opportunities for learning. Thirty-two parents from diverse backgrounds participated in the first part of the study. Twenty-one of these parents participated in the test–retest study. The sample was culturally diverse and included parents of 6- to 11-year-old children with and without disabilities who have average or above intellect. Results from the psychometric analyses show that the CHORES has strong reliability and validity. The variance in children's task performance and overall levels of assistance supports the utility of this measure for capturing differences among children in the extent of their participation. Stability of parents’ responses over time is strong both for performance (ICC, r=0.88) and for assistance (ICC, r=0.92) scores. The validity of the CHORES is supported by the parents’ judgments of the importance of involving their children in household tasks. The CHORES is easy to complete, considers the parent's perspective, and provides a way to collect information on children's participation in household tasks. The CHORES provides a mechanism to learn more about factors that influence children's participation in household tasks, changes in their responsibilities over time, and outcomes from their participation in these tasks.
A rapid and precise method for sampling and determining the oxygen isotope ratio of atmospheric water vapor.

A quantitative method for cryogenically sampling atmospheric water vapor on the temporal scale of 10 to 15 min in the field or laboratory is described. The sample apparatus is lightweight, affordable, and easy to assemble. The method allows for H2O:CO2 equilibration within the same sampling tubes and hence increases turnaround time for delta18O analysis. Quantitative analysis in the laboratory showed recovery of a vaporized, known, 18O water standard to 0.2 per thousand precision.
Establishment of a Poliovirus Oral Infection System in Human Poliovirus Receptor-Expressing Transgenic Mice That Are Deficient in Alpha/Beta Interferon Receptor

ABSTRACT Poliovirus (PV) is easily transferred to humans orally; however, no rodent model for oral infections has been developed because of the alimentary tract's low sensitivity to the virus. Here we showed that PV is inactivated by the low pH of the gastric contents in mice. The addition of 3% NaHCO3 to the viral inoculum increased the titer of virus reaching the small intestine through the stomach after intragastric inoculation of PV. Transgenic mice (Tg) carrying the human PV receptor (hPVR/CD155) gene and lacking the alpha/beta interferon receptor (IFNAR) gene (hPVR-Tg/IfnarKO) were sensitive to the oral administration of PV with 3% NaHCO3, whereas hPVR-Tg expressing IFNAR were much less sensitive. The virus was detected in the epithelia of the small intestine and proliferated in the alimentary tract of hPVR-Tg/IfnarKO. By the ninth day after the administration of a virulent PV, the mice had died. These results suggest that IFNAR plays an important role in determining permissivity in the alimentary tract as well as the generation of virus-specific immune responses to PV via the oral route. Thus, hPVR-Tg/IfnarKO are considered to be the first oral infection model for PV, although levels of anti-PV antibodies were not elevated dramatically in serum and intestinal secretions of surviving mice when hPVR-Tg/IfnarKO were administered an attenuated PV.
Temporal Information Extraction

Research on information extraction (IE) seeks to distill relational tuples from natural language text, such as the contents of the WWW. Most IE work has focussed on identifying static facts, encoding them as binary relations. This is unfortunate, because the vast majority of facts are fluents, only holding true during an interval of time. It is less helpful to extract PresidentOf(Bill-Clinton, USA) without the temporal scope 1/20/93 — 1/20/01. This paper presents TIE, a novel, information-extraction system, which distills facts from text while inducing as much temporal information as possible. In addition to recognizing temporal relations between times and events, TIE performs global inference, enforcing transitivity to bound the start and ending times for each event. We introduce the notion of temporal entropy as a way to evaluate the performance of temporal IE systems and present experiments showing that TIE outperforms three alternative approaches.
Two Listeria monocytogenes Vaccine Vectors That Express Different Molecular Forms of Human Papilloma Virus-16 (HPV-16) E7 Induce Qualitatively Different T Cell Immunity That Correlates with Their Ability to Induce Regression of Established Tumors Immortalized by HPV-161

Two recombinant Listeria monocytogenes (rLm) strains were produced that secrete the human papilloma virus-16 (HPV-16) E7 protein expressed in HPV-16-associated cervical cancer cells. One, Lm-E7, expresses and secretes E7 protein, whereas a second, Lm-LLO-E7, secretes E7 as a fusion protein joined to a nonhemolytic listeriolysin O (LLO). Lm-LLO-E7, but not Lm-E7, induces the regression of the E7-expressing tumor, TC-1, established in syngeneic C57BL/6 mice. Both recombinant E7-expressing rLm vaccines induce measurable anti-E7 CTL responses that stain positively for H-2Db E7 tetramers. Depletion of the CD8+ T cell subset before treatment abrogates the ability of Lm-LLO-E7 to impact on tumor growth. In addition, the rLm strains induce markedly different CD4+ T cell subsets. Depletion of the CD4+ T cell subset considerably reduces the ability of Lm-LLO-E7 to eliminate established TC-1 tumors. Surprisingly, the reverse is the case for Lm-E7, which becomes an effective anti-tumor immunotherapeutic in mice lacking this T cell subset. Ab-mediated depletion of TGF-β and CD25+ cells improves the effectiveness of Lm-E7 treatment, suggesting that TGF-β and CD25+ cells are in part responsible for this suppressive response. CD4+ T cells from mice immunized with Lm-E7 are capable of suppressing the ability of Lm-LLO-E7 to induce the regression of TC-1 when transferred to tumor-bearing mice. These studies demonstrate the complexity of L. monocytogenes-mediated tumor immunotherapy targeting the human tumor Ag, HPV-16 E7.
Evidence from Molecular Fingerprinting of Limited Spread of Drug-Resistant Tuberculosis in Texas

ABSTRACT To determine the contribution of recent transmission to spread of drug-resistant tuberculosis in Texas, we performed IS6110-based and pTBN12-based restriction fragment length polymorphism (RFLP) analyses on Mycobacterium tuberculosisisolates. Isolates collected from 201 patients in Texas between 1992 and 1994 were studied. The distribution of cases was strikingly focal. All cases were reported from 35 of the 254 counties in Texas, and 74% (148 of 201) were reported from only 9 counties. One hundred sixty-one (80%) of the patients had M. tuberculosis isolates with unique RFLP patterns, and 41 (20%) patients were in 20 clusters, each comprising 2 to 3 patients. The largest number of cases of drug-resistant tuberculosis were reported in counties bordering Mexico, but the percentage of clustered cases was highest in northeast Texas and in counties that included the cities of Dallas, Fort Worth, and Houston. Compared to nonclustered patients, clustered patients were more likely to be African American and to have been born in the United States. Clustered patients were significantly more likely to be from the same geographic area, and clustered patients from the same geographic area were more likely to have isolates with identical drug susceptibility patterns, suggesting that they were linked by recent transmission. In 11 of 20 clusters, clustered patients were from geographically separate regions, and most isolates did not have identical drug susceptibility patterns, suggesting that tuberculosis was contracted from a common source in the remote past. Based on the low percentage of clustered cases and the small cluster size, we conclude that there is no evidence for the extensive transmission of drug-resistant tuberculosis in Texas.
Unified Approach to Pore Size Characterization of Microporous Carbonaceous Materials from N2, Ar, and CO2 Adsorption Isotherms†

We present a unified approach to pore size characterization of microporous carbonaceous materials such as activated carbon and carbon fibers by nitrogen, argon, and carbon dioxide adsorption at standard temperatures, 77 K for N2 and Ar and 273 K for CO2. Reference isotherms of N2, Ar, and CO2 in a series of model slit-shaped carbon pores in the range from 0.3 to 36 nm have been calculated from the nonlocal density functional theory (NLDFT) using validated parameters of intermolecular interactions. Carbon dioxide isotherms have also been generated by the grand canonical Monte Carlo (GCMC) method based on the 3-center model of Harris and Yung. The validation of model parameters includes three steps: (1) prediction of vapor−liquid equilibrium data in the bulk system, (2) prediction of adsorption isotherm on graphite surface, (3) comparison of the NLDFT adsorption isotherms in pores to those of GCMC simulations, performed with the parameters of fluid-fluid interactions, which accurately reproduce vapor−liqui.
Neurogenesis by Progenitor Cells in the Ischemic Adult Rat Hippocampus

Background and Purpose— Recently, there has been great interest in adult neurogenesis. We investigated whether transient forebrain ischemia could influence the proliferation of neuronal progenitor in the subgranular zone (SGZ) of the rat hippocampus and whether aging could influence the neurogenesis after ischemia. Methods— Male Wistar rats were subjected to 4-vessel occlusion model. We used a bromodeoxyuridine (BrdU) labeling method to identify the postproliferation cells and double-immunostaining with confocal microscopy to determine the cell phenotype. Results— The number of BrdU-positive cells in the SGZ increased ≈5.7-fold 8 days after ischemia, compared with the control. BrdU-positive cells formed clusters, which suggested that these cells had divided from an original progenitor cell, and expressed Musashi1 (Msi1), a marker of neural stem/progenitor cells. Although astrocytes also expressed Msi1 in the adult brain, Msi1-positive cells that formed clusters in the SGZ did not express glial fibrillary acidic protein, an astrocyte marker. About 70% of all BrdU-positive cells in the SGZ represented the neuronal phenotype 4 weeks after the BrdU injection. Although proliferation of progenitor cells was stimulated in both young and older animals, aging accelerated the reduction in newborn cells after ischemia. Conclusions— Our results indicate that ischemic stress stimulated the proliferation of neuronal progenitor cells in the SGZ of both young and old rats but resulted in increased neurogenesis only in young animals. Our findings will be important in developing therapeutic intervention to enhance endogenous neurogenesis after brain injury.
Load-Dependent Increases in Delay-Period Alpha-Band Power Track the Gating of Task-Irrelevant Inputs to Working Memory

Studies exploring the role of neural oscillations in cognition have revealed sustained increases in alpha-band power (ABP) during the delay period of verbal and visual working memory (VWM) tasks. There have been various proposals regarding the functional significance of such increases, including the inhibition of task-irrelevant cortical areas as well as the active retention of information in VWM. The present study examines the role of delay-period ABP in mediating the effects of interference arising from on-going visual processing during a concurrent VWM task. Specifically, we reasoned that, if set-size dependent increases in ABP represent the gating out of on-going task-irrelevant visual inputs, they should be predictive with respect to some modulation in visual evoked potentials resulting from a task-irrelevant delay period probe stimulus. In order to investigate this possibility, we recorded the electroencephalogram while subjects performed a change detection task requiring the retention of two or four novel shapes. On a portion of trials, a novel, task-irrelevant bilateral checkerboard probe was presented mid-way through the delay. Analyses focused on examining correlations between set-size dependent increases in ABP and changes in the magnitude of the P1, N1 and P3a components of the probe-evoked response and how such increases might be related to behavior. Results revealed that increased delay-period ABP was associated with changes in the amplitude of the N1 and P3a event-related potential (ERP) components, and with load-dependent changes in capacity when the probe was presented during the delay. We conclude that load-dependent increases in ABP likely play a role in supporting short-term retention by gating task-irrelevant sensory inputs and suppressing potential sources of disruptive interference.
Effect of Ouabain on Endothelium‐Dependent Relaxation of Human Resistance Arteries

Inhibition of active sodium transport by ouabain was found to cause concentration- and time-dependent impairment of acetylcholine-induced relaxation in human resistance arteries with a significant effect at 100 pM. The reduced acetylcholine response was attributable to inhibition of the A^-monomethyl L-argjnine-sensItive but not the indomethacin-sensitive component of relaxation. Relaxation by sodium nitroprusside was not affected by ouabain, suggesting that inhibition of sodium transport, directly or indirectly, must affect synthesis or release of endothelium-derived relaxing factor rather than its effector pathway. These results do not support the existence of an additional endothelium-derived relaxing factor other than endothelium- derived relaxing factor, which is dependent on sodium pump activity. The finding that inhibition of sodium transport has a profound effect on vascular relaxation may have implications in the pathogenesis of certain forms of hypertension.
Emotional Expression Online

Laughter “punctuates” speech, occurring during pauses, at phrase boundaries, and before and after statements and questions—the places where punctuation would be placed in a transcript of a conversation. Such punctuation indicates that language is dominant over laughter in competition for the vocal tract because laughter seldom interrupts spoken phrases. The punctuation effect is shown here to extend to emoticon placement in website text messages, a nonvocal linguistic medium. As in earlier studies of speaking and manual signing, the phrase structure of language was preserved, indicating the regulation of emotional expression by a common, higher-order linguistic process.
The ratio index for budgeted learning, with applications

In the budgeted learning problem, we are allowed to experiment on a set of alternatives (given a fixed experimentation budget) with the goal of picking a single alternative with the largest possible expected payoff. Constant factor approximation algorithms for this problem were developed by Guha and Munagala by rounding a linear program that couples the various alternatives together. In this paper we present an index for this problem, which we call the ratio index, which also guarantees a constant factor approximation. Index-based policies have the advantage that a single number (i.e. the index) can be computed for each alternative irrespective of all other alternatives, and the alternative with the highest index is experimented upon. This is analogous to the famous Gittins index for the discounted multi-armed bandit problem. The ratio index has several interesting structural properties. First, we show that it can be computed in strongly polynomial time. Second, we show that with the appropriate discount factor, the Gittins index and our ratio index are constant factor approximations of each other, and hence the Gittins index also gives a constant factor approximation to the budgeted learning problem. Finally, we show that the ratio index can be used to create an index-based policy that achieves an O(1)-approximation for the finite horizon version of the multi-armed bandit problem. Moreover, the policy does not require any knowledge of the horizon (whereas we compare its performance against an optimal strategy that is aware of the horizon). This yields the following surprising result: there is an index-based policy that achieves an O(1)-approximation for the multi-armed bandit problem, oblivious to the underlying discount factor.
The relationship of deep and surface study approaches on factual and applied test‐bank multiple‐choice question performance

With the advent of online test banks and large introductory classes, instructors have often turned to textbook publisher‐generated multiple‐choice question (MCQ) exams in their courses. Multiple‐choice questions are often divided into categories of factual or applied, thereby implicating levels of cognitive processing. This investigation examined the influence student study approaches have on performance of shallow compared to deep, cognitive process outcomes measured by scores on factual versus application MCQ test bank questions respectively. Fifty‐six introduction to psychology students, aged 18–52 years, completed a modified version of the Revised Two‐Factor Study Process Questionnaire (R‐SPQ‐2F) to access deep or surface study approaches. Mid‐term and final exam MCQ were equally divided between factual and application questions from the textbook publisher test bank. Overall, students performed significantly better on factual MCQ, with older students achieving higher factual and applied scores. Results suggest younger students tend to use a surface approach to study, with reproduction of what was taught to meet minimum requirements. With age statistically controlled, analyses demonstrated that the surface learning approach negatively impacts MCQ performance on questions categorised as factual and applied more than a deep learning approach benefits MCQ performance.
Escape from the GDR, 1961–1989: Hybrid Exit Repertoires in a Disintegrating Leninist Regime1

Leading theorists contend that "exit" and its many manifestations do not fit the "contentious collective action" model. This article argues, however, that exit is frequently the only collective action available to average people in authoritarian regimes. In such regimes, collective exit may take a variety of forms, hybridized here from the elements of traditional and modern repertoires under varying conditions of opportunity and framing. Descriptions of hybrid exit episodes from the German Democratic Republic, 1961–89, are based on annual reports by Amnesty International, on secondary sources before 1989, and, primarily, on accounts from six international presses for 1989.
The Attributional Approach to Emotion and Motivation: Introduction to a Special Section of Emotion Review

In this introduction to the special section on the attributional approach to emotion and motivation, the character of Weiner’s attributional theory as an appraisal theory is discussed. I argue that the theory, although focusing on appraisal dimensions related to causal attribution, is actually a fairly general appraisal theory of emotion. Distinctive features of the attributional approach are its pioneering role in emotion research, its emphasis on the functional role of emotions, particularly for the motivation of action, and the existence of a large supportive data base. Given the solid evidence compiled by attributional researchers for emotion-specific effects of emotion on motivation, I propose that future research should focus on the details of the mental mechanisms through which emotions affect motivation, and formulate five questions that could guide this inquiry.
Researching 40 years of learning for work: the experiences of one cohort of workers

Using previously unanalysed data from a lost study—the Adjustment of Young Workers to Work Situations and Adult Roles (1962–1964)—and data from a subsequent restudy, this paper contributes to debates on vocational education by examining three themes. First, the methodological issues raised by undertaking a restudy are discussed. Second, the young workers’ initial workplace learning experiences in the 1960s are examined with an emphasis on commitment to learning and training. Third, links between initial training experiences and the subsequent learning experiences in later careers are explored. We conclude that high levels of commitment to workplace learning were evident throughout the life‐course of this group. However, significantly, this commitment existed only when the training available was on‐the‐job and the links between learning and working practice were clear. Formal learning opportunities were deemed unimportant and seen as existing for the benefit of the employer, not the employee.
