The effects of technostress within the context of employee use of ICT

The main purpose of the present study is to help managers cope with the negative effects of technostress on employee use of ICT. Drawing on transaction theory of stress (Cooper, Dewe, & O’Driscoll, 2001) and information systems (IS) continuance theory (Bhattacherjee, 2001) we investigate the effects of technostress on employee intentions to extend the use of ICT at work. Our results show that factors that create and inhibit technostress affect both employee satisfaction with the use of ICT and employee intentions to extend the use of ICT. Our findings have important implications for the management of technostress with regard to both individual stress levels and organizational performance. A key implication of our research is that managers should implement strategies for coping with technostress through the theoretical concept of technostress inhibitors. 2014 Elsevier Ltd.

Workplace bullying and the risk of cardiovascular disease and depression.

AIMS
To examine exposure to workplace bullying as a risk factor for cardiovascular disease and depression in employees.


METHODS
Logistic regression models were related to prospective data from two surveys in a cohort of 5432 hospital employees (601 men and 4831 women), aged 18-63 years. Outcomes were new reports of doctor diagnosed cardiovascular disease and depression during the two year follow up among those who were free from these diseases at baseline.


RESULTS
The prevalence of bullying was 5% in the first survey and 6% in the second survey. Two per cent reported bullying experiences in both surveys, an indication of prolonged bullying. After adjustment for sex, age, and income, the odds ratio of incident cardiovascular disease for victims of prolonged bullying compared to non-bullied employees was 2.3 (95% CI 1.2 to 4.6). A further adjustment for overweight at baseline attenuated the odds ratio to 1.6 (95% CI 0.8 to 3.5). The association between prolonged bullying and incident depression was significant, even after these adjustments (odds ratio 4.2, 95% CI 2.0 to 8.6).


CONCLUSIONS
A strong association between workplace bullying and subsequent depression suggests that bullying is an aetiological factor for mental health problems. The victims of bullying also seem to be at greater risk of cardiovascular disease, but this risk may partly be attributable to overweight.
Silver alloy wire bonding

In semiconductor packaging, wire bonding is the main technology for electrical connections between chip and leadframe or substrate. Gold wire bonding has the advantages of a fast bonding process, excellent electrical property and stable chemical property. It has been widely used in various electronic packages. Gold prices have been raised significantly over the last few years. Many manufactures have been investigating ways to replace the conventional gold wire with various new materials. Copper wire bonding is an alternative interconnection technology. Cu wire has superior electrical and thermal conductivities as well as higher tensile strength, elongation and better “ball neck” strength. On the other hand, the higher hardness of Cu wire requires higher ultrasonic power and bonding force, which lead to high risk of cratering for ball bonding and tearing for wedge bonding. These will cause some package limitation and wire bonder machine downtime or low units per hour (UPH). Ag alloy wire has low Young's modulus and hardness property. It is a low cost wire bonding solution other than gold wire. In this study, Ag alloy wire is proposed as an alternative to Au bonding wire. Emphasis is placed on the wire bonding workability and reliability of using Ag-Au-Pd alloy wire for TSOP package. Also, wire bonding parameter such as electronic flame off (EFO), bond force, ultrasonic power, heat block temperature and time for ball and wedge bonding are optimized. Furthermore, the response for parameter optimization is determined by the Dage bond tester. Package reliability is determined through environmental tests that include pressure cooker test (PCT), temperature cycle test (TCT) and high temperature storage life test (HTSL). The tested samples were studied by focused ion beam (FIB), scanning electron microscopy (SEM) and energy dispersive spectrometer analyses (EDS). Intermetallic compound growth behavior during reliability test is characterized and compared to Al-Au and Al-Cu systems. Ag-Al didn't have excessive volume variation and void occurrence to get better bonding performance during various reliability tests.
Twelve Years of National Football League Concussion Data

BACKGROUND
Concussion in the National Football League (NFL) remains an important issue. An initial description of the injury epidemiology involved 6 years from 1996 to 2001.


HYPOTHESIS
The increased attention to concussions may have resulted in team physicians being more conservative in treating players in recent years.


STUDY DESIGN
Two consecutive 6-year periods (1996-2001 and 2002-2007) were compared to determine changes in the circumstances associated with the injury, the patterns of signs and symptoms, and the players' time loss from participation in the NFL.


METHODS
During 2002-2007, concussions were recorded by NFL team physicians and athletic trainers using the same standardized reporting form used from 1996 to 2001. Player position, type of play, concussion signs and symptoms, loss of consciousness, and medical action taken were recorded.


RESULTS
There were 0.38 documented concussions per NFL game in 2002-2007-7.6% lower than the 0.42 in the earlier period (1996-2001). The injury rate was lower in quarterbacks and wide receivers but significantly higher in tight ends during the second 6 years. The most frequent symptoms were headaches and dizziness; the most common signs were problems with information processing and immediate recall. During 2002-2007, a significantly lower fraction of concussed players returned to the same game, and more were removed from play. Most concussed players (83.5%) returned to play in < 7 days; the percentage decreased to 57.4% with loss of consciousness. The number of players returning in < 7 days was 8% lower during 2002-2007 and 25% lower for those with loss of consciousness.


CONCLUSION
The most recent 6 years of NFL concussion data show a remarkable similarity to the earlier period. However, there was a significant decrease in the percentage of players returning to the same game, and players were held out of play longer.


CLINICAL RELEVANCE
There was a more conservative management of concussion in NFL players from 2002 to 2007 even though the clinical signs and symptoms remained similar to the earlier 6-year period.
Qualitative Process Theory

Objects move, collide, flow, bend, heat up, cool down, stretch, compress, and boil. These and other things that cause changes in objects over time are intuitively characterized as processes. To understand commonsense physical reasoning and make programs that interact with the physical world as well as people do we must understand qualitative reasoning about processes, when they will occur, their effects, and when they will stop. Qualitative process theory defines a simple notion of physical process that appears useful as a language in which to write dynamical theories. Reasoning about processes also motivates a new qualitative representation ]:or quantity in terms of inequalities, called the quantity space. This paper describes the basic concepts of qualitative process theory, several different kinds of reasoning that can be performed with them, and discusses its implications for causal reasoning. Several extended examples illustrate the utility of the theory, including figuring out that a boiler can blow up, that an oscillator with friction will eventually stop, and how to say that you can pull with a string, but not push with it. I . I n t r o d u c t i o n Many kinds of changes occur in physical situations. Objects move, collide, flow, bend, heat up, cool down, stretch, compress, and boil. These and the other things that cause changes in objects over time are intuitively characterized by processes. Much of formal physics consists of characterizations of processes by differential equations that describe how the parameters of objects change over time. But the notion of process is richer and more structured than this. We often reach conclusions about physical processes based on very little information. For example, we know that if we heat water in a sealed container the water can eventually boil, and if we continue to do so the container can explode. To understand commonsense physical reasoning we must understand how to reason qualitatively about processes, when they will occur, their effects, and when they will stop. This paper describes qual i ta t ive process theory, which I have been developing for this purpose.

The efficacy of pneumatic compression stockings in the prevention of pulmonary embolism after cardiac surgery.

INTRODUCTION
Pneumatic compression stocking (PCS) devices have been introduced to decrease the incidence of postoperative deep venous thrombosis (DVT). However, their role in the prophylaxis against pulmonary embolism (PE) remains unclear. This study was undertaken to compare the prophylactic effectiveness of subcutaneous heparin (SCH) alone vs the combined use of PCS and SCH in the prevention of PE following cardiac surgery.


METHODS
We studied 2,551 consecutive patients who underwent cardiac surgery over a 10-year period. They were randomly allocated to two groups. Group A included 1,196 patients who were treated with 5,000 U of SCH every 12 h and group B included 1,355 patients treated with a combined prophylactic regimen of PCS and SCH.


RESULTS
The diagnosis of PE was established in 69 patients by either high-probability ventilation perfusion scan, pulmonary angiogram, or autopsy. The incidence of PE in group A patients was 4% (48/1,196) and in group B was 1.5% (21/1,355). The concomitant use of bilateral PCS and SCH reduced the frequency of postoperative PE in 62% in comparison to the prophylaxis with SCH alone (p < 0.001).


CONCLUSIONS
These data suggest that the combined prophylactic method of bilateral PCS and SCH is superior to SCH alone in the prevention of PE after cardiac surgery.
Segmentation techniques for recognition of Arabic-like scripts: A comprehensive survey

Arabic script based text recognition system has been a popular field of research for many years that can be used in the learning and teaching process to the students and educators how to read and understand educational contents of Arabic script. The challenging nature of Arabic script recognition has attracted the attention of researchers from both industry and academic circles but these efforts have not achieved good results until now. Segmentation of Urdu script when written in Nasta’liq writing style is very difficult task due to the complexity of writing style as compare to Naskh writing style. Good segmentation is one of the reasons for high accuracy. Character segmentation has been a critical phase of the OCR process. The higher recognition rates for isolated characters as compare to results of words or connected character well illustrate the importance of segmentation. Current study investigates the recent work for character segmentation and challenges for segmentation for Arabic script based languages.
Effects of pantoprazole on dual antiplatelet therapy in stable angina pectoris patients after percutaneous coronary intervention.

BACKGROUND
Our aim was to prospectively assess the potential influence of pantoprazole therapy on the antiplatelet effects of acetylsalicylic acid (ASA) and clopidogrel (CLO) in stable angina pectoris (SAP) patients after percutaneous coronary intervention (PCI).


METHODS
Forty-four patients with SAP (CCS I-III) and successful PCI with stent implantation were enrolled into the study. The patients were divided into group proton pump inhibitors (PPI): 23 patients with indications for PPI (F/M = 9/14; age = 64 ± 9; standard therapy + 20 mg pantoprazole) and the control group (group C): 21 patients (F/M = 6/15; age = 64 ± 8; standard therapy). The platelet function analysis in whole blood based on impedance aggregometry (ASPI, COL, ADP, TRAP tests) using Multiplate--V2.02.11 was performed 18-24 h after the PCI + CLO loading dose (600 mg) and 30 days after PCI.


RESULTS
Both baseline patient characteristics and clinical outcomes were comparable between the study groups. There were no differences in the mean values of the platelets (PTL) tests measured at the 30(th) day after PCI between both groups (PPI vs. C: ASPI: 24.6 ± 10.0 vs. 42.1 ± 14.8 U, COL: 32.9 ± 8.6 vs. 34.0 ± 7.7 U, ADP: 26.8 ± 12.4 vs. 30.4 ± 8.1 U, TRAP: 78.7 ± 16.6 vs. 78.1 ± 22.6 U, p = ns). The mean delta values of the PTL tests (18-24 h post-PCI/30 days post-PCI) were also comparable between the groups. The PTL aggregometry results were related to time (ADP, ASPI, TRAP vs. time, p = 0.001; COL vs. time, p = 0.03)--the baseline values of ADP, ASPI, COL and TRAP tests were smaller than those measured after the one-month observation.


CONCLUSION
Pantoprazole treatment does not impair the efficacy of dual antiplatelet therapy in patients with SAP after PCI.
Web searching for sexual information: an exploratory study

Sexuality on the Internet takes many forms and channels, including chat rooms discussions, accessing Websites or searching Web search engines for sexual materials. The study of Web sexual queries provides insight into sexual-related information-seeking behavior, of value to Web users and providers alike. We qualitatively analyzed 58,027 queries from a log of 1,025,910 Excite Web user queries from 1999. We found that sexual and non-sexual-related queries exhibited differences in session duration, query outcomes, and search term choices. Implications for sexual information seeking and Web systems are discussed.
Solid Waste Management Planning using GIS and Remote Sensing Technologies Case Study Aurangabad City, India

There is a tremendous amount of loss in terms of environmental degradation, health hazards and economic descend due to direct disposal of waste. It is better to segregate the waste at the initial generation stages rather than going for a later option which is inconvenient and expensive as well. There has to be an appropriate planning for proper waste management by means of analysing the waste situation of the area. This paper deals with, how geographical information system can be used as a decision support tool for planning waste management. A model is designed for the case study area in an Indian city for the purpose of planning waste management. Waste management issues are considered to solve some of the present situation problems like proper allocation and relocation of waste bins, check for unsuitability and proximity convenience due to waste bins to the users. Proposal of recyclable waste bins for the required areas and future suggestions in this regard. The designed model has been implemented on the data prepared from the satellite images for the analysis. The results suggest some modification in the existing system which is expected to reduce the waste management workload to a certain extent
Scaling behavior of kinetic orientational distributions for dilute nematic polymers in weak shear

Analytical descriptions of shear-aligned nematic monodomains have a long history across continuum, mesoscopic and mean-field kinetic models. Their value lies in the prediction of explicit scaling properties of the orientational distribution and of normal and shear stresses, with respect to molecular and flow parameters. At the coarsest scale of continuum Leslie-Ericksen theory [1, 2], an explicit macroscopic alignment angle formula always exists in terms of bulk Miesowicz viscosities; the theory applies only to nematic (highly concentrated) liquids with low molecular weight and in the weak flow limit [3, 4, 5, 6]. At mesoscales, orientation tensor models [7, 8, 9, 10, 11] apply at all concentrations and shear rates; explicit ”Leslie angle” formulas exist only in the weak shear limit [12, 13, 14, 15, 16, 17, 18, 19], inheriting hysteresis in alignment properties from the quiescent isotropic-nematic transition. Since the fundamental results of Onsager [20] for quiescent nematic equilibria, exact probability distribution functions (PDFs) of kinetic theory have proven elusive for flow-driven nematic states. In their stead, flow-aligned and unsteady PDF formulas, elegant though implicit, have been derived by Kuzuu-Doi [3, 4] and Semenov [21] by weak flow asymptotic analysis, and by Marrucci and Maffettone [22] by restriction to two dimensions. A simpler problem concerns the dilute concentration regime where the quiescent equilibrium is isotropic, non-degenerate, and stable, which is the focus of this paper. Using weak-flow asymptotics, we explicitly construct, and establish stability of, stationary, shear-perturbed PDFs for dilute concentrations; our formulas prove unsteady tumbling of perturbed isotropic states cannot occur. Exact scaling properties are predicted, including explicit Leslie alignment angle and degree-of-alignment (birefringence) formulas, as well as normal and shear stresses, in terms of molecular parameters and normalized shear rate for dilute nematic polymers. Our formulas apply except in a neighborhood of the isotropic instability transition, which
A shortened postpartum magnesium sulfate prophylaxis regime in pre-eclamptic women at low risk of eclampsia.

OBJECTIVE
To determine whether magnesium sulfate (MgSO(4)) prophylaxis is needed for up to 24 hours postpartum in all patients with pre-eclampsia.


METHODS
In a randomized open clinical trial conducted in a tertiary health center in India between September 2008 and April 2010, 150 women with severe pre-eclampsia who received intrapartum MgSO(4) and delivered at more than 2 weeks gestation were enrolled. After 6hours postpartum, the participants were randomized to continue receiving (control group) or to discontinue (intervention group) MgSO(4), and outcomes were compared.


RESULTS
Administration of MgSO(4) had to be reinstituted for 1 woman in the intervention group. Under the current protocol in the institution, all 75 women in the intervention group would have received MgSO(4) for 24 hours postpartum. A significant reduction in time spent by the doctors (P<0.001) and nurses (P<0.001) was seen in the intervention group. The pain score in the intervention group was significantly less (P<0.001), and women in the intervention group were able to look after themselves better (P<0.001).


CONCLUSION
For women at low risk for postpartum eclampsia, a shortened (6-hour) MgSO(4) regime was as effective for seizure prophylaxis as the conventional 24-hour regime, with significant benefits in terms of cost and morbidity.
Event Studies in Information Systems Research: A Review

Event studies, which look at stock market reactions to assess corporate business events, represent a relatively new research approach in the information systems field. In this paper we present a systematic review of thirty event studies related to information technology. After a brief discussion of each of the papers included in our review, we call attention to several limitations of the published studies and propose possible future research avenues.
Madison Avenue Meets Wall Street : Mutual Fund Families , Competition and Advertising

We examine the effects of mutual fund families’ strategic decisions on investor flows into the families. Similar to evidence found at the individual fund level, investor flows as a function of a family’s past performance display an increasing and convex relation for high performing families. We also find an association between a family’s flows and its relative levels of advertising expenditures with a significant positive effect for high relative advertisers only. Also a relation exists between family flows and choice of distribution channels and expense ratios. Madison Avenue Meets Wall Street: Mutual Fund Families, Competition and Advertising Investment companies, particularly open-end mutual funds, have been the fastest growing segment of the institutional investor community in recent years. Despite the importance of this institutional investor class, questions still remain concerning the supply and demand for the financial services they provide. Regarding the supply, although early research tended to focus on individual funds (primarily growth funds), more recent research has considered the mutual fund family as the relevant unit of measure. This is an important distinction because many decisions are made from a family, rather than individual fund, perspective since most mutual funds are managed by an investment advisory company that manages a family of such funds. Decisions such as advertising budget, what and when to advertise, the types and number of funds to offer, which distribution channels to pursue, service quality, or individual manager appointments primarily originate on the mutual fund family level. Thus, to fully understand the motivation and impact of these types of decisions, one needs to focus on the mutual fund family complex. In this paper we address the supply and demand issues by testing hypotheses concerning how the fund family strategic decisions affect investor demand. That is, we examine how the family’s strategic decisions affect aggregate net flows of assets under management. Although the investment management company that sponsors the funds is certainly interested in the level of flows to each of their individual funds, they view those funds as a series of products, with the central interest being in the aggregate flows to the entire family of funds. We focus in particular on the advertising decision, but in 1 Recent papers on mutual fund families include Khorana and Servaes (1999, 2003), Mamaysky and Spiegel (2002), Gaspar, Massa and Matos (2003), Massa (2003), Sigglekow (2003), Nanda, Wang and Zheng (2004), Elton, Gruber and Green (2004) and Kempf and Ruenzi (2004, 2005).
