Conflict, facilitation, and individual coping styles across the work and family domains

Purpose – The purpose of this paper is to explore the relationships between four general coping styles, work and family conflict, and work and family facilitation in a simultaneous equations frameworkDesign/methodology/approach – Data from the MIDUS study were analyzed using two‐staged least squares regression to incorporate the reciprocity between the work and family domains into the model. Hypotheses about direct action, advice seeking, positive thinking, and cognitive reappraisal as they affect work family (W‐F) and family‐work (F‐W) conflict were tested. The impact of the coping styles on work and family facilitation has not been studied before and was also included.Findings – The efficacy of individual coping styles on conflict and the relationships between coping and facilitation were not uniform and varied depending on the source domain. Positive thinking was associated with higher W‐F and F‐W facilitation. Direct‐action was associated with lower F‐W conflict and higher F‐W facilitation. Reappraisa.
A New Approach to Online Testing of TGFSOP-based Ternary Toffoli Circuits

Previous work presented a simple technique for converting an ESOP-based Boolean reversible circuit into an online testable circuit. This paper builds on the previous work by extending its application to circuits consisting of cascades of ternary Toffoli gates. The technique is applied to an existing cascade of ternary Toffoli gates, and requires that a single additional line be added to facilitate the propagation of any faults that are identified, as well as modification and/or addition of some gates. The modified circuit can detect online any single-bit errors that occur within the circuit. Experimental results compare very favourably to the only other known approach.
Pareto Optima and Competitive Equilibria with Adverse Selection and Moral Hazard

This paper explores the extent to which standard, general equilibrium analysis of Pareto optima and of competitive equilibria can be applied to environments with moral hazard and adverse selection problems. Allowing for lotteries, contracts with random components, we first establish that an adverse-selection insurance economy, a moral-hazard insurance economy, a signaling economy, and a private-information labor market economy are all special cases of a simple, general structure. We then show that techniques for characterizing Pareto optimal contracts as solutions to concave programming problems are useful and nice and appear to be broadly applicable; allowing for lotteries, we show how to characterize the optimal allocations for the adverse-selection insurance and labor market economies. We then show that standard existence and optimality theorems for competitive equilibria apply in the linear space containing lotteries if agents with characteristics which are distinct and privately observed at the time of initial trading enter the economy-wide resource constraints in a homogeneous way (other kinds of diversity are not critical). For economies with moral hazard which satisfy the homogeneity condition, competitive contract markets single out a subset of the optima and thus can be consistent with apparent unemployment and with a random allocation of labor supplied though all households are averse to risk. The adverse-selection insurance and signaling economies, however, do not satisfy the homogeneity condition and are difficult to decentralize efficiently with a price system.
Handedness and hemispheric language dominance in healthy humans.

In most people the left hemisphere of the brain is dominant for language. Because of the increased incidence of atypical right-hemispheric language in left-handed neurological patients, a systematic association between handedness and dominance has long been suspected. To clarify the relationship between handedness and language dominance in healthy subjects, we measured lateralization directly by functional transcranial Doppler sonography in 326 healthy individuals using a word-generation task. The incidence of right-hemisphere language dominance was found to increase linearly with the degree of left-handedness, from 4% in strong right-handers (handedness = 100) to 15% in ambidextrous individuals and 27% in strong left-handers (handedness = -100). The relationship could be approximated by the formula: f1.gif" BORDER="0">. These results clearly demonstrate that the relationship between handedness and language dominance is not an artefact of cerebral pathology but a natural phenomenon.
Successful development of viable blastocysts from enhanced green fluorescent protein transgene‐microinjected mouse embryos: Comparison of culture media

To improve efficiency of transgenesis, we compared M16 and CZB embryo culture media, supporting development to blastocysts of FVB/N mouse pronuclear‐eggs, microinjected with enhanced green fluorescent protein (EGFP) transgene. When EGFP‐injected‐eggs were cultured (120 hr), blastocyst development was significantly (P < 0.03) higher in M16 medium (72.5 ± 2.4%) than that in CZB (13.2 ± 4.3%) or CZBG (CZB with 5.6 mM glucose at 48 hr culture) (62.1 ± 3.7%) media. Blastocyst development of noninjected embryos was higher in M16 (92.0 ± 2.6%) and CZBG (83.9 ± 3.9%) media than in CZB (31.9 ± 2.8%) medium (P < 0.0001). However, percentages of morulae at 72 hr were comparable in all treatments. Developed blastocysts were better in M16 than in CZB or CZBG media. Consistent with this, mean cell number per blastocyst, developed from injected embryos, was significantly (P < 0.002) higher in M16 medium (79.6), than those in CZB (31.3) or CZBG media (60.7); similar with noninjected embryos. Cell allocation to trophectoderm (TE) and inner cell mass (ICM), i.e., TE:ICM ratio, for injected blastocysts in M16 (3.0) was less than (P < 0.05) those in CZB (4.2) and CZBG (4.4) media; similar with noninjected blastocysts. Moreover, blastocysts, developed in M16 and CZBG media, hatched, attached, and exhibited trophoblast outgrowth; 18% of them showed EGFP‐expression. Importantly, blastocysts from M16 medium produced live transgenic “green” pups (11%) following embryo transfer. Taken together, our results indicate that supplementation of glucose, at 48 hr of culture (CZBG), is required for morula to blastocyst transition; M16 medium, containing glucose from the beginning of culture, is superior to CZB or CZBG for supporting development of biologically viable blastocysts from EGFP‐transgene‐injected mouse embryos.

Flow Control in High-Speed Networks with Long Delays

The flow control component of a transport layer protocol regulates the natural data transmission rate of an application to match the service rate offered by the network. In this paper, we study the problems that arise when a flow control protocol has to deal with long delays in receiving information about network state, and has large amounts of data transmitted but unacknowledged. We describe three representative flow control protocols, and study their behavior on a suite of three benchmark scenarios. Our simulations indicate that in networks with large delays, protocols that are insensitive to the state of the network, or that require multiple round trip times to attain the optimal transmission rate, will perform poorly. The packet-pair protocol, which avoids these problems, is shown to perform well under rather adverse conditions.
Intraspecific Variation in Zucchini Yellow Mosaic Virus Transmission by Myzus persicae and the Impact of Aphid Host Plant

Abstract Three isofemale lines of Myzus persicae (Sulzer), two lines collected from and reared on a brassicaceous host, and one line collected from and reared on a malvaceous host, were evaluated for their efficiency of transmitting Zucchini yellow mosaic virus (family Potyviridae, genus Potyvirus, ZYMV). In the first experiment, the transmission efficiencies of two clones from Brassicaceae (B1 and B2) were 52.0 and 60.8%, respectively, and these transmissions were not significantly different. In a second experiment, the transmission efficiencies of the clone on Malvaceae (M1) and clone B2 were significantly different at 35.6 and 55.7%, respectively. Further experiments evaluated host-related mechanisms that may have contributed to the differential transmissions observed between clones M1 and B2. Studies on short-term feeding showed that aphids continuously reared on okra, Abelmoschus esculentus (L.) Moench (malvaceous host), and those that were reared on okra and allowed a 24-h preacquisition feeding period on mustard, Brassica juncea (L.) Czern (brassicaceous host), had significantly lower transmission than aphids continuously maintained on mustard. Aphids reared on mustard and allowed a 24-h preacquisition feeding period on okra had intermediate transmission efficiency. In long-term host association studies, we found that aphids reared on mustard had significantly higher transmission efficiency than those reared on okra, and aphids reared first on okra and then switched to mustard had a transmission efficiency that was intermediate and not significantly different from the other two treatments. Our study reveals the existence of intraspecific variation in the transmission of ZYMV by M. persicae, and it suggests that to accurately assess the transmission capability of ZYMV by this species, multiple clones should be examined. Furthermore, the host plant on which the aphid is reared as well as the host plant on which it feeds just before virus acquisition contribute to ZYMV transmission efficiency of M. persicae.
Communication and Terrorism: A Terror Management Theory Perspective

As terrorism continues to raise the specter of death to levels of salience best measured on a global scale, terror management theory (TMT) offers valuable insights for communication theorists regarding the nature and psychology of terrorism. TMT provides a metatheoretic framework, which can help to unify a diverse range of communication theory perspectives. Following a review of TMT's analysis of certain socioemotional factors associated with the human potential for existential anxiety and intercultural conflict, this paper examines how TMT relates to and illuminates diverse communication theory orientations bearing on a range of issues related to the causes and costs of terrorism.
A study of the lived experiences of registered nurses who have provided end-of-life care within an intensive care unit.

BACKGROUND End-of-life care (EOLC) in the intensive care unit (ICU) has received little attention in the literature in comparison to the considerable amount of existing literature available on EOLC in other areas of nursing. The ethos of the ICU is to preserve life, but as many patients die in this environment, EOLC should be an integral part of the ICU nurse's role. This qualitative study explored the experiences of ICU nurses who had provided EOLC to patients and their families. METHOD Participants were purposively recruited within one local ICU (n=5). A semi-structured interview format was used to guide in-depth interviews. FINDINGS The themes identified from the interview analysis were; use of integrated care systems, communication, the environment, education and training, staff distress. CONCLUSIONS The findings suggest that ICU nurses do not feel adequately prepared to give proficient EOLC. Those who felt more confident in EOLC had learned what to do over time. Appropriate training, support and improved communication between staff, patients and families is necessary for good EOLC in ICUs.
Low prevalence of progranulin mutations in Finnish patients with frontotemporal lobar degeneration

Background and purpose: Mutations in the progranulin (PGRN) gene have recently been associated with frontotemporal lobar degeneration (FTLD). The frequency of these mutations varies between populations. The aim of this study was to determine mutations and genetic variations of the PGRN gene in Finnish patients with FTLD and FTLD with associated motor neuron disease (FTLD‐MND).
A two-dimensional click model for query auto-completion

Query auto-completion (QAC) facilitates faster user query input by predicting users' intended queries. Most QAC algorithms take a learning-based approach to incorporate various signals for query relevance prediction. However, such models are trained on simulat- ed user inputs from query log data. The lack of real user interaction data in the QAC process prevents them from further improving the QAC performance. In this work, for the first time we collect a high-resolution QAC query log that records every keystroke in a QAC session. Based on this data, we discover two user behaviors, namely the horizontal skipping bias and vertical position bias which are crucial for rele- vance prediction in QAC. In order to better explain them, we pro- pose a novel two-dimensional click model for modeling the QAC process with emphasis on these behaviors. Extensive experiments on our QAC data set from both PC and mobile devices demonstrate that our proposed model can accurate- ly explain the users' behaviors in interacting with a QAC system, and the resulting relevance model significant improves the QAC performance over existing click models. Furthermore, the learned knowledge about the skipping behavior can be effectively incorpo- rated into existing learning-based models to further improve their performance.
Torque vectoring system for improving manoeuvrability of light electric vehicles

Electric vehicles are already a reality although their development and spread in urban context are encountering resistance especially due to the lack of electric vehicle charging facilities. Small electric in-wheel motors are perfectly suited to urban driving and their low electric energy consumption can also guarantee a sufficient daily mileage. The present paper proposes a rear wheel drive electric vehicle powered by two hub motors whose torque requests can be independently commanded by two separate inverters. This torque management fits well with a torque vectoring (TV) system that can improve the vehicle manoeuvrability, even at low speed. The TV can be implemented in a low cost programmable control board that can be used in any type of vehicle. The considered TV system was tested in a prototype quadri-mobile developed in an industrial research and development program called HiQuad.
Majority Bootstrap Percolation on the Hypercube

In majority bootstrap percolation on a graph G, an infection spreads according to the following deterministic rule: if at least half of the neighbours of a vertex v are already infected, then v is also infected, and infected vertices remain infected forever. We say that percolation occurs if eventually every vertex is infected. The elements of the set of initially infected vertices, A ⊂ V(G), are normally chosen independently at random, each with probability p, say. This process has been extensively studied on the sequence of torus graphs [n]d, for n = 1,2, . , where d = d(n) is either fixed or a very slowly growing function of n. For example, Cerf and Manzo [17] showed that the critical probability is o(1) if d(n) ≤ log*n, i.e., if p = p(n) is bounded away from zero then the probability of percolation on [n]d tends to one as n → ∞. In this paper we study the case when the growth of d to ∞ is not excessively slow; in particular, we show that the critical probability is 1/2 + o(1) if d ≥ (log log n)2 log log log n, and give much stronger bounds in the case that G is the hypercube, [2]d.

Copulas for information retrieval

In many domains of information retrieval, system estimates of document relevance are based on multidimensional quality criteria that have to be accommodated in a unidimensional result ranking. Current solutions to this challenge are often inconsistent with the formal probabilistic framework in which constituent scores were estimated, or use sophisticated learning methods that make it difficult for humans to understand the origin of the final ranking. To address these issues, we introduce the use of copulas, a powerful statistical framework for modeling complex multi-dimensional dependencies, to information retrieval tasks. We provide a formal background to copulas and demonstrate their effectiveness on standard IR tasks such as combining multidimensional relevance estimates and fusion of results from multiple search engines. We introduce copula-based versions of standard relevance estimators and fusion methods and show that these lead to significant performance improvements on several tasks, as evaluated on large-scale standard corpora, compared to their non-copula counterparts. We also investigate criteria for understanding the likely effect of using copula models in a given retrieval scenario.
Changes in children’s time with parents: United States, 1981–1997

In this paper we examine changes in the time American children spent with their parents between 1981 and 1997, and the contribution to these changes made by shifting patterns of female labor force participation, family structure, and parental education. We decompose changes into the parts attributable to changes in demographic characteristics and the parts probably due to changes in behavior. In general, children’s time with parents did not decrease over the period; in two-parent families it increased substantially. Population-level changes in demographic characteristics exerted only small direct effects on the time children spent with parents.
Social Sampling Explains Apparent Biases in Judgments of Social Environments

How people assess their social environments plays a central role in how they evaluate their life circumstances. Using a large probabilistic national sample, we investigated how accurately people estimate characteristics of the general population. For most characteristics, people seemed to underestimate the quality of others’ lives and showed apparent self-enhancement, but for some characteristics, they seemed to overestimate the quality of others’ lives and showed apparent self-depreciation. In addition, people who were worse off appeared to enhance their social position more than those who were better off. We demonstrated that these effects can be explained by a simple social-sampling model. According to the model, people infer how others are doing by sampling from their own immediate social environments. Interplay of these sampling processes and the specific structure of social environments leads to the apparent biases. The model predicts the empirical results better than alternative accounts and highlights the importance of considering environmental structure when studying human cognition.
CaveUDK: a VR game engine middleware

Previous attempts at developing immersive versions of game engines have faced difficulties in achieving both overall high performance and preserving reusability of software developments. In this paper, we present a high-level VR middleware based on one of the most successful commercial game engines: the Unreal® Engine 3.0 (UE3). We describe a VR framework implemented as an extension to the Unreal® Development Kit (UDK) supporting CAVE"-like installations. Our approach relies on a distributed architecture reinforced by specific replication patterns to synchronize the user's point of view and interactions within a multi-screen installation. Our performance benchmarks indicated that our immersive port does not affect the game engine performance, even with complex real-time applications, such as fast-paced multiplayer First Person Shooter (FPS) games or high-resolution graphical environments with 2M+ polygons. A user study also demonstrated the capacity of our VR middleware to elicit high spatial presence while maintaining low cybersickness effects. With free distribution, we believe such a platform can support future Entertainment and VR research.
Survey Response Rates and Overall Patient Satisfaction Scores: What Do They Mean?

Within the health care community, more and more emphasis is being placed on patient satisfaction. This study was undertaken in a midwestern, nonprofit, 300-bed acute care hospital to gain a better understanding of how nonresponse rates and patient characteristics affect patient satisfaction scores. With a response rate of 34.2%, it appears that nonresponse bias may have an impact. When looking at variables that may affect the overall score, the multiple regression model used in this analysis was able to explain only 7.5% of the variability in the overall satisfaction score seeming to indicate the unpredictability of the score. This study supports the need to analyze groups of patients rather than patients as a whole to determine what affects their response, both within and between health care organizations.
More Schooling, More Children: Compulsory Schooling Reforms and Fertility in Europe

We study the relationship between education and fertility, exploiting compulsory schooling reforms in Europe as source of exogenous variation in education. Using data from 8 European countries, we assess the causal effect of education on the number of biological kids and the incidence of childlessness. We find that more education causes a substantial decrease in childlessness and an increase in the average number of children per woman. Our findings are robust to a number of falsification checks and we can provide complementary empirical evidence on the mechanisms leading to these surprising results.
Loss of TGF-b Responsiveness in Prostate Stromal Cells Alters Chemokine Levels and Facilitates the Development of Mixed Osteoblastic/Osteolytic Bone Lesions

Loss of TGF-b type II receptor (TbRII, encoded by Tgfbr2) expression in the prostate stroma contributes to prostate cancer initiation, progression, and invasion.We evaluated whether TbRII loss also affected prostate cancer bone metastatic growth. Immunohistologic analysis revealed that TbRII expression was lost in cancer-associated fibroblasts in human prostate cancer bone metastatic tissues. We recapitulated the human situation with a conditional stromal Tgfbr2 knockout (Tgfbr2-KO) mouse model. Conditioned media from primary cultured Tgfbr2-KOor control Tgfbr2-flox prostatic fibroblasts (koPFCMorwtPFCM, respectively) were applied toC4-2B prostate cancer cells before grafting the cells tibially.We found that koPFCMpromoted prostate cancer cell growth in the bone and development of early mixed osteoblastic/osteolytic bone lesions. Furthermore, the koPFCM promoted greater C4-2B adhesion to type-I collagen, themajor component of bonematrix, compared to wtPFCMtreated C4-2B. Cytokine antibody array analysis revealed that koPFCM had more than two-fold elevation in granulocyte colony-stimulating factor and CXCL1, CXCL16, and CXCL5 expression relative to wtPFCM. Interestingly, neutralizing antibodies of CXCL16 orCXCL1were able to reduce koPFCM-associatedC4-2B type-I collagen adhesion to that comparable with wtPFCM-mediated adhesion. Collectively, our data indicate that loss of TGF-b responsiveness in prostatic fibroblasts results in upregulation of CXCL16 and CXCL1 and that these paracrine signals increase prostate cancer cell adhesion in the bone matrix. These microenvironment changes at the primary tumor site can mediate early establishment of prostate cancer cells in the bone and support subsequent tumor development at the metastatic site.
