Occupational Balance: A Time Use Study of Industrial Shift Workers

Despiteresearch providing evidence for an increased prevalence of ill-health conditions, cognitive difficulties, sbcial difficulties, and impaired work performance among night shift -workers, few researchers have irtvestigated potential causes. Grounded in occupational science theory,-occupational bal*"i lOnl and subjective quality of life (SQOL) were investigated among shift workers. Additional analysis included an examination of health . status, cognitive Aifficulties, social difficulties, and lifestyle choices in relation to work shift, OB, and SQOL. Twenty-one full time workers of a car parts manufacturing plant completed survey packets containing a demographic sheet, time diary, and the Psychological General Wel-being Index (PGWBI). Statistically significant relationships between work shift and SQOL were found, specifically with anxiety, self-control, general health, vitality, and overall SQOL. There was no statistically significant difference between day and night shift workers for prevalence of OB. There were no statistically significant differences for work shift, OB, oTSQOL scores in relation to the listed health variables. There were statistically silnificant relationships bbtween work shift and SQOL with some of the cognitive and Social diffiCulties. Occupational balance was measured in two ways as a post hoc analysis of the relationship between SQOL and OB. There was no statistically significant relationship between SQoiland:Marino-Schorn's time-based definition of OB. There wefe statistically significint relationships between 3 out of 6 SQOL domains and Matuska and Christiansen's needs-based definition, Life Balance (LB). Results indicated that there was poor occupationu, Our*"" among the total sample of shift workers and poor subjective quality of life among night shift workers in this study. It is recommended that shift workers of various emplbyment aieas remain a target population for occupational therapy researchers.
Telephone versus Face-to-Face Interviewing of National Probability Samples with Long Questionnaires: Comparisons of Respondent Satisficing and Social Desirability Response Bias

The last 50 years have seen a gradual replacement of face-to-face interviewing with telephone interviewing as the dominant mode of survey data collection in the United States. But some of the most expensive and large-scale nationally funded, long-term survey re- search projects involving national area-probability samples and long questionnaires retain face-to-face interviewing as their mode. In this article, we propose two ways in which shifting such surveys to random digit dialing (RDD) telephone interviewing might affect the quality of data acquired, and we test these hypotheses using data from three na- tional mode experiments. Random digit dialing telephone respondents were more likely to satisfice (as evidenced by no-opinion responding, nondifferentiation, and acquiescence), to be less cooperative and en- gaged in the interview, and were more likely to express dissatisfaction with the length of the interview than were face-to-face respondents, despite the fact that the telephone interviews were completed more quickly than the face-to-face interviews. Telephone respondents were also more suspicious about the interview process and more likely to present themselves in socially desirable ways than were face-to-face respondents. These findings shed light on the nature of the survey re- sponse process, on the costs and benefits associated with particular survey modes, and on the nature of social interaction generally.
Geometrically uniform TCM codes over groups based on multidimensional 4-PSK and 8-PSK signals

The theory of geometrically uniform (GU) signal constellations and linear codes over groups is applied to the case of multidimensional phase shift keying (PSK) signals. Tables of GU partitions of multidimensional PSK constellations are used to construct good GU codes over nonbinary abelian groups. The authors consider L /spl times/ 4 PSK and L /spl times/ 8 PSK constellations used to transmit information rates of 1 and 2 bits per signaling interval, respectively, and present a systematic constructive procedure to search for good codes over generating groups (Z/sub 4/)/sup L/ and (Z/sub 8/)/sup L/. Rotational invariance conditions for the codes are easily incorporated into the search algorithm. In some cases, the codes found improve over the codes known so far. The geometrical uniformity of codes allows a very easy performance evaluation. A set of curves of error event probability for some selected codes is presented. <<ETX>>
A numerical study of submarine–landslide–generated waves and run–up

A mathematical model is derived to describe the generation and propagation of water waves by a submarine landslide. The model consists of a depth–integrated continuity equation and momentum equations, in which the ground movement is the forcing function. These equations include full nonlinear, but weak frequency–dispersion, effects. The model is capable of describing wave propagation from relatively deep water to shallow water. Simplified models for waves generated by small seafloor displacement or creeping ground movement are also presented. A numerical algorithm is developed for the general fully nonlinear model. Comparisons are made with a boundary integral equation method model, and a deep–water limit for the depth–integrated model is determined in terms of a characteristic side length of the submarine mass. The importance of nonlinearity and frequency dispersion in the wave–generation region and on the shoreline movement is discussed.
Ligand based virtual screening to find novel inhibitors against plant toxin Ricin by using the ZINC database

Ricin is known as a potent toxin against animals. It consists of two chains, Ricin Toxin A (RTA) and Ricin Toxin B (RTB). The toxic effect is known to be caused by RTA. Inhibitors for RTA with less efficiency have been reported. Hence, it is of interest to identify new inhibitors. Virtual screening methods (computer aided drug designing) to find similar molecules in drug database were used for screening new inhibitors against RTA. We used the structure of RTA in complex with Pteroic acid (PDB code: 1BR6) as target molecule. Ligand based virtual screening approach was used in which the known inhibitory molecule Pteroic acid (PTA) served as a template to identify similar ligands from the ZINC database. These ligands were docked inside the binding pocket of RTA by using the MVD (Molegro Virtual Docker). This approach successfully identified six novel compounds. These docked ligands interacted with Asn78, Ala79, Val81, Gly121 and Ser176 amino acids, which are key residues of the RTA active site. Three compounds in particular, ZINC05156321 (6, 7 diphenylpteridin-4-ol), ZINC05156324 (6, 7-bis (3-fluorophenyl) pteridin-4-ol) and ZINC08555900 (6, 7-bis (4-fluorophenyl)-1H-pteridin-4-one), showed higher binding affinity in comparison to PTA, with high interaction energy, better space fitting and electrostatic interactions. These molecules should be tested for in vitro and in vivo activities in future for consideration as effective inhibitors.

Accurate Liver Extraction Using a Local-Thickness-Based Graph-Cut Approach

— This article presents an accurate and automatic approach to extract a liver from CT images for oncologic surgery planning. Our algorithm exploits graph cut segmentation, which perform global optimization. The quality of graph cut segmentation strongly depends on the edge image that gives prior knowledge about locations of foreground and background regions. In order to get a good edge image, a liver candidate region is extracted based on three types of liver structure models: intensity model, shape model, and blood vessel model. Moreover, the "local-thickness" image of the liver candidate region is used as the edge image. The experimental results show that the use of local-thickness edge image can avoid the over-extraction of anatomical structures surrounding the liver.
Studies on the Electrical Potential Profile across Rabbit Ileum

When isolated strips of mucosal rabbit ileum are bathed by physiological electrolyte solution the electrical potential difference (PD) across the brush border (ψmc) averages 36 mv, cell interior negative. Rapid replacement of Na in the mucosal solution with less permeant cations, Tris or choline, results in an immediate hyperpolarization of ψmc. Conversely, replacement of choline in the mucosal solution with Na results in an abrupt depolarization of ψmc. These findings indicate that Na contributes to the conductance across the brush border. The presence of actively transported sugars or amino acids in the mucosal solution brings about a marked depolarization of ψmc and a smaller increase in the transmural PD (Δψms). It appears that the Na influx that is coupled to the influxes of amino acids and sugars is electrogenic and responsible for the depolarization of ψmc. Under control conditions Δψms can be attributed to the depolarization of ψmc together with the presence of a low resistance transepithelial shunt, possibly the lateral intercellular spaces. However, quantitatively similar effects of amino acids on ψmc are also seen in tissues poisoned with metabolic inhibitors or ouabain. Under these conditions Δψmc is much smaller than under control conditions. Thus, the depolarization of ψmc might not account for the entire Δψms, observed in nonpoisoned tissue. An additional electromotive force which is directly coupled to metabolic processes might contribute to the normal Δψms.
Designing Innovative Learning Activities Using Ubiquitous Computing

In this paper we present our pedagogical and technological approach for supporting the design of novel situated learning activities that can be conducted both, outside the school and in the classroom. One main goal is to enhance the content of the curricula by bringing multimedia resources and mobile support to outdoor settings thus enriching the field experience. In order to illustrate these ideas we describe the outcomes of a trial we have conducted with thirty elementary school children. Moreover, we present the ubiquitous computing solutions we developed in order to support learning activities in the field of history. The results of our experiments indicate that children enjoyed learning in these kinds of environments where mobile devices are used in situ, thus supporting the learning activities in the context of which they are taking place.
Dorsal hindbrain ablation results in rerouting of neural crest migration and changes in gene expression, but normal hyoid development.

Our previous studies have shown that hindbrain neural tube cells can regulate to form neural crest cells for a limited time after neural fold removal (Scherson, T., Serbedzija, G., Fraser, S. E. and Bronner-Fraser, M. (1993). Development 188, 1049-1061; Sechrist, J., Nieto, M. A. , Zamanian, R. T. and Bronner-Fraser, M. (1995). Development 121, 4103-4115). In the present study, we ablated the dorsal hindbrain at later stages to examine possible alterations in migratory behavior and/or gene expression in neural crest populations rostral and caudal to the operated region. The results were compared with those obtained by misdirecting neural crest cells via rhombomere rotation. Following surgical ablation of dorsal r5 and r6 prior to the 10 somite stage, r4 neural crest cells migrate along normal pathways toward the second branchial arch. Similarly, r7 neural crest cells migrate primarily to the fourth branchial arch. When analogous ablations are performed at the 10-12 somite stage, however, a marked increase in the numbers of DiI/Hoxa-3-positive cells from r7 are observed within the third branchial arch. In addition, some DiI-labeled r4 cells migrate into the depleted hindbrain region and the third branchial arch. During their migration, a subset of these r4 cells up-regulate Hoxa-3, a transcript they do not normally express. Krox20 transcript levels were augmented after ablation in a population of neural crest cells migrating from r4, caudal r3 and rostral r3. Long-term survivors of bilateral ablations possess normal neural crest-derived cartilage of the hyoid complex, suggesting that misrouted r4 and r7 cells contribute to cranial derivatives appropriate for their new location. In contrast, misdirecting of the neural crest by rostrocaudal rotation of r4 through r6 results in a reduction of Hoxa-3 expression in the third branchial arch and corresponding deficits in third arch-derived structures of the hyoid apparatus. These results demonstrate that neural crest/tube progenitors in the hindbrain can compensate by altering migratory trajectories and patterns of gene expression when the adjacent neural crest is removed, but fail to compensate appropriately when the existing neural crest is misrouted by neural tube rotation.
Potential Role of Carotenoids as Antioxidants in Human Health and Disease

Carotenoids constitute a ubiquitous group of isoprenoid pigments. They are very efficient physical quenchers of singlet oxygen and scavengers of other reactive oxygen species. Carotenoids can also act as chemical quenchers undergoing irreversible oxygenation. The molecular mechanisms underlying these reactions are still not fully understood, especially in the context of the anti- and pro-oxidant activity of carotenoids, which, although not synthesized by humans and animals, are also present in their blood and tissues, contributing to a number of biochemical processes. The antioxidant potential of carotenoids is of particular significance to human health, due to the fact that losing antioxidant-reactive oxygen species balance results in “oxidative stress”, a critical factor of the pathogenic processes of various chronic disorders. Data coming from epidemiological studies and clinical trials strongly support the observation that adequate carotenoid supplementation may significantly reduce the risk of several disorders mediated by reactive oxygen species. Here, we would like to highlight the beneficial (protective) effects of dietary carotenoid intake in exemplary widespread modern civilization diseases, i.e., cancer, cardiovascular or photosensitivity disorders, in the context of carotenoids’ unique antioxidative properties.
Fostering EFL learners´ literacies through local inquiry in a multimodal experience

Addressing students’ social reality through the exploration of community inquiries in the English language class can create learning environments for developing students´ language and literacies. This paper addresses the question in what ways community inquiries create opportunities for students to explore social and cultural issues in their neighborhoods using multimodality. It discusses the role community inquiries play in the development of literacy practices of a group of 10 th graders in their EFL class. This descriptive qualitative project carried out at a public institution in the south of Bogota, Colombia involved 40 participants. The goal of the institutional project is to transform the way students relate to the community in order to create local knowledge. Data was collected through videotape recordings of students´ presentations, teacher´s journal, students´ interactions in Facebook and students´ blogs in a 2-year period. The findings reveal that teachers and students enacted a critical pedagogy through an inquiry curriculum that explored community issues and allowed participants to become inquirers of their own realities. Students´ language learning was evident in multimodal texts in English in their blogs, in the use of EFL in their oral presentations and in their comments in response to peers in Facebook and their blogs.
Does Java Have Alternatives ?

At first sight, Java’s position as the de-facto standard for portable software distributed across the Internet seems virtually unassailable. Interestingly enough, however, it is surprisingly simple to provide alternatives to the Java platform, using the plug-in mechanism supported by the major commercial World Wide Web browsers. We are currently developing a comprehensive infrastructure for mobile software components. This is a long-term research activity and not directly related to Java and the World Wide Web. However, purely as a technology demonstration, we have r ecently started a s mall spin-off project called “Juice” with the intent of extending our experimental mobile-code platform into the realm of the commercial Internet. Juice is implemented in the form of a browser plug-in that generates native code on-the-fly. Although our software distribution format and run-time architecture are fundamentally different from Java’s, once that the appropriate Juice plug-in has been installed on a Windows PC or a Macintosh computer, end-users can no longer distinguish between applets that are based on Java and those that are based on Juice. The two kinds of applets can even coexist on the same web-page. This, however, means that Java can in principle be complemented by alternative technologies (or even gradually be displaced by something better) with far fewer complications than most people seem to assume. As dynamic code generation technology matures further, it will become less important which code-distribution format has the largest “market share”; many such formats can be supported concurrently. Future executable-content developers may well be able to choose from a wide range of platforms, probably including several dialects of Java itself.
Misuse Intrusion Detection Using a Fuzzy-Metaheuristic Approach

In this paper, we use simulated annealing heuristics for constructing an intrusion detection system (IDS). The proposed IDS combines the learning ability of simulated annealing heuristics with the approximate reasoning method of fuzzy systems. The use of simulated annealing is an effort to effectively explore the large search space related to intrusion detection problems, and find the optimum set of fuzzy if-then rules. The aim of this paper is to present the capability of simulated annealing based fuzzy system to deal with intrusion detection classification problem as a new real-world application area. Experiments were performed with KDD-Cup99 intrusion detection benchmark data set.
Institutional Logics: The Next Big Challenge for Information Systems Cross-Cultural Research?

ABSTRACT While there is continued interest in traditional culture studies in global IS research, the theoretical foundation of culture studies is shifting to the newer Theory of Institutional Logics. Institutional Logics are socially constructed, historical patterns of both symbolic systems (i.e., culture) and material practices that legitimize social order. Typical institutions include family, religion, the state, the market, professions, community, and the corporation. This article unpacks the definition of Institutional Logics in order to provide an introduction to the theory and provides methodological guidelines in pursuing this type of research. It also provides suggestions for areas of future global research in IS. A call is made for further research in IS using the Theory of Institutional Logics in order to address the predominantly Western-centric point of view in IS research.
Improving throughput for heterogeneous traffic in IEEE802.11e EDCA

An analytical model is proposed to describe the priority schemes of the Enhanced Distributed Channel Access (EDCA) mechanism of the IEEE 802.11e standard. EDCA provides class-based differentiated Quality of Service (QoS) to IEEE 802.11 wireless local area networks (WLANs). However, One of the main challenges with 802.11e EDCA is the configuration of the open parameters of this mechanism, namely Arbitration Inter Frame Space (AIFS), Contention Window(CW) and transmission opportunity (TXOP). In this paper, we focus on the optimal configuration of parameter CW in order to improve the throughput performance of the WLAN. We present an approach to set parameter CW according to channel status. Then, based on this model, we search for the optimal throughput with EDCA. Finally, we show the model is calculated numerically and validated against simulation results.
Contributor's Performance, Participation Intentions, Its Influencers and Project Performance

Software project performance largely depends on the software development team. Studies have shown that interest and activity levels of contributors at any time significantly affect project success measures. This dissertation provides suggestions to enhance contributors' performance and participation intentions to help improve project performance. To do so, we mine historical data in software repositories from a two-pronged approach: 1) To assess contributors' performance to identify strengths and areas of improvement. 2) To measure the influence of factors on contributors' participation and performance, and provide suggestions that help advance contributor's engagement. The methodology used in this study leverage empirical techniques, both quantitative and qualitative, to conduct the analysis. We believe that the insights presented here will help contributors improve their performance. Also, we expect managers and business analysts to benefit from the suggestions to revise factors that negatively influence contributors' engagement and hence improve project performance.
Effects of zero-filled interpolation on cervical magnetic resonance angiographic measurement.

BACKGROUND AND PURPOSE The aim of this study was to assess the effect of zero-filled interpolation (ZIP) on measurements of the cervical arteries because its benefits on the accuracy and precision of measurements in medium-sized arteries remains unknown. METHODS Three observers measured 36 computer-simulated vessels (2-6.8 mm) and 130 normal cervical vessels (assessed with two-dimensional time-of-flight MR angiography) from 512-, 256-, and 256-ZIP matrix source images. The accuracy and precision of measurement was assessed for each matrix by using the Student t test and F test of variance, respectively. The effect of vessel size and matrix placement on measurement error was determined by means of linear regression and the Student t test, respectively. RESULTS No significant difference was observed between simulated measurements obtained on the 512 matrix and their true value. The 256 matrix caused overestimation of vessel diameter compared with 512 matrix (mean bias, 0.3 mm for computer-simulated vessels and 0.1 mm for normal vessels). This effect was reduced with ZIP, by a mean of 0.1 mm for both groups (P <.03). Precision was not affected by the matrix size or ZIP, and vessel size and matrix placement did not alter the measurement error. CONCLUSION Vessel diameter is overestimated on 256-matrix MR angiographic source images. ZIP reduces this overestimation; however, the effect is small and unlikely to be clinically important.
