An illusion of power: qualitative perspectives on abortion decision-making among teenage women in Sweden.

CONTEXT
Swedish law permits abortion at the request of a pregnant woman until the 18th week of gestation. However, the extent to which the decision is truly the woman's own is subject to debate; women are often influenced, directly or indirectly, by the attitudes of their partners, family and friends or by social norms.


METHODS
Individual in-depth interviews about the pregnancy and the abortion decision were conducted 3-4 weeks postabortion with 25 women aged 16-20 at different periods in 2003, 2005 and 2007. Interviews were audio-taped, transcribed verbatim and analyzed using latent content analysis.


RESULTS
The main reasons for unplanned pregnancy were underestimation of pregnancy risk and inconsistent contraceptive use. Pregnancy prevention was perceived as the woman's responsibility. The abortion decision was accompanied by mixed emotions, and was seen as a natural yet difficult choice. Social norms and the negative attitudes of family and friends strongly influenced the decision. Partners and parents were regarded as the most important sources of support. After the abortion, the women felt pressured by contraceptive counselors to use highly effective contraceptives despite their previous negative experiences or worries about side effects.


CONCLUSIONS
Swedish teenagers' basic right to decide whether to have an abortion may be limited by societal norms and disapproval of teenage childbearing. Given the perception that women are responsible for contraception, programs need to emphasize that pregnancy prevention is a shared responsibility; greater efforts to include males in prevention practices are needed.
The association of psoriasiform rash with anti-tumor necrosis factor (anti-TNF) therapy in inflammatory bowel disease: a single academic center case series.

BACKGROUND & AIMS
Anti-tumor necrosis factors (anti-TNF) including infliximab, adalimumab and certolizumab pegol are used to treat Crohn's disease (CD) and ulcerative colitis (UC). Paradoxically, while also indicated for the treatment of psoriasis, anti-TNF therapy has been associated with development of psoriasiform lesions in IBD patients and can compel discontinuation of therapy. We aim to investigate IBD patient, clinical characteristics, and frequency for the development of and outcomes associated with anti-TNF induced psoriasiform rash.


METHODS
We identify IBD patients on anti-TNFs with an onset of a psoriasiform rash. Patient characteristics, duration of anti-TNF, concomitant immunosuppressants, lesion distribution, and outcomes of rash are described.


RESULTS
Of 1004 IBD patients with exposure to anti-TNF therapy, 27 patients (2.7%) developed psoriasiform lesions. Psoriasiform rash cases stratified by biologic use were 1.3% for infliximab, 4.1% for adalimumab, and 6.4% for certolizumab. Average time on treatment (206.3weeks) and time on treatment until onset of psoriasiform lesions (126.9weeks) was significantly higher in the infliximab group. The adalimumab group had the highest need for treatment discontinuation (60%). The majority (59.3%) of patients were able to maintain on anti-TNFs despite rash onset. Among patients that required discontinuation (40.7%), the majority experienced improvement with a subsequent anti-TNF (66.7%).


CONCLUSION
27 cases of anti-TNF associated psoriasiform lesions are reported. Discontinuation of anti-TNF treatment is unnecessary in the majority. Dermatologic improvement was achieved in the majority with a subsequent anti-TNF, suggesting anti-TNF induced psoriasiform rash is not necessarily a class effect.
Timing discriminator for pulsed time-of-flight laser rangefinding measurements

A time-pickoff circuit based on constant fraction discriminator (CFD) timing principle has been developed for pulsed time-of-flight laser rangefinding. It is based on the detection of the crossing point of the trailing edge of the original timing pulse and the leading edge of its delayed replica with a fast ECL comparator. A simplified theory has been presented for the sources of the walk error in constant fraction time discriminators, and three different comparator types have been tested in the CFD developed. It has been noticed that if there are not any crosstalk disturbances, the walk error produced by the limited gain-bandwidth product of the comparator is the dominating walk error source and that walk error can be decreased to +/1 mm in a 1:10 dynamic range of input pulses by adding an external offset voltage between the input nodes of the comparator. The bandwidth of the preamplifier used was 100 kHz100 MHz.
Open-label, multicenter, phase 3 extension study of the safety and efficacy of donepezil in patients with Alzheimer disease.

BACKGROUND
Donepezil hydrochloride is a selective acetylcholinesterase inhibitor approved for the symptomatic treatment of mild to moderately severe Alzheimer disease (AD). Controlled clinical trials of up to 24 weeks have demonstrated that donepezil treatment (5 and 10 mg/d) significantly improves cognition and global function.


OBJECTIVE
To investigate the long-term benefits of donepezil treatment in patients with AD.


DESIGN
Multicenter, open-label, 144-week extension of 2 US phase 3, double-blind, placebo-controlled clinical trials: a 15-week study (12 weeks of treatment followed by a 3-week placebo washout) and a 30-week study (24 weeks of treatment followed by a 6-week placebo washout).


INTERVENTIONS
All patients (N = 763) initially received donepezil, 5 mg/d, for 6 weeks, after which an increase to 10 mg/d was encouraged.


MEASURES
Primary efficacy measures were the Alzheimer's Disease Assessment Scale-cognitive subscale and the Clinical Dementia Rating-Sum of the Boxes.


RESULTS
After the shorter 3-week placebo washout, donepezil-associated benefits remained above original baseline values for an additional 24 weeks of open-label treatment. Benefits on Alzheimer's Disease Assessment Scale-cognitive subscale scores for patients who received 10 mg/d in the double-blind study were evident compared with the other groups for 108 weeks of open-label treatment. In contrast, donepezil-associated benefits were lost after the 6-week placebo washout, and scores decreased below original baseline values for all patient groups. Although scores improved relative to the new open-label study baseline scores after drug use was restarted, patients remained below original baseline values. The most common adverse events were associated with the nervous and digestive systems and were generally mild and transient; 17% of patient discontinuations were associated with adverse events.


CONCLUSIONS
Donepezil is an effective and safe drug for the long-term symptomatic treatment of mild to moderately severe AD for up to 144 weeks (2.8 years), and sustained treatment may confer some advantages.
Time-motion characteristics and physiological responses of small-sided games in elite youth players: the influence of player number and rule changes.

The aim of this study was to examine acute physiological responses and time-motion characteristics associated with 4 soccer-specific small-sided game (SSG) formats (3 vs. 4 players, 3 vs. 3 players + floater, 5 vs. 6 players, and 5 vs. 5 players + floater) and 4 rule changes in elite youth soccer players. Sixteen male youth soccer players (mean +/- SD: age = 15.6 +/- 0.8 years, stature = 170.8 +/- 6.6 cm, body mass = 67.5 +/- 6.2 kg, and 20-m shuttle run estimated Vo2max = 57.4 +/- 3.7 mlxkgxmin) participated in the study, in which heart rate (HR), rating of perceived exertion (RPE), blood lactate (La), and time-motion characteristics were recorded. The rule change requiring extra sprint running had a greater effect on the time-motion characteristics than all other rule modifications but no effect on acute %HRmax, La, and RPE. Rule changes had no effect on RPE. Fixed underload teams (i.e., lower number of players compared with the opponent team) recorded a significantly higher RPE compared with the fixed overload teams, although there were no differences in %HRmax and La. The major practical findings are that subtle changes in SSGs playing rules can influence the physiological, perceptual, and time-motion responses in young elite soccer players. Rules that are related to a team's chances of scoring may improve player motivation and thereby increase training intensity during SSGs. There were no differences between fixed and variable formats in terms of physiological and perceptual responses, although both may provide useful technical-tactical training. Coaches should take care in designing different soccer SSGs as each rule or game format change may influence exercise intensity independently.
A novel VM workload prediction using Grey Forecasting model in cloud data center

In recent years, the resource demands in cloud environment have been increased incrementally. In order to effectively allocate the resources, the workload prediction of virtual machines (VMs) is a vital issue that makes the VM allocation more instantaneous and reduces the power consumption. In this paper, we propose a workload prediction method using Grey Forecasting model to allocate VMs, which is the first string in the research field. Firstly, we utilize the time-dependent of workload at the same period in every day, and forecast the VM workload tendency towards increasing or decreasing. Next, we compare the predicted value with previous time period on workload usage, then determine to migrate which VM wherein the physical machine (PM) for the balanced workload and lower power consumption. The simulation results show that our proposed method not only uses the fewer data to predict the workload accurately but also allocates the resource of VMs with power saving.
Umbilical Pilonidal Sinus, an Underestimated and Little-Known Clinical Entity: Report of Two Cases

BACKGROUND Umbilical pilonidal sinus (UPS) is a rare disease of young, hirsute, dark men with deep navels and poor personal hygiene. UPS could easily be misdiagnosed and mistreated due to its rarity and lack of awareness of the condition by physicians. However, the diagnosis is easy to establish with physical examination and a detailed history. Although it is being diagnosed and reported more frequently, there is still no consensus regarding best treatment options. CASE REPORT In this report, we present two cases of UPS, one in a man and one in a woman, who had typical symptoms of pain, swelling, and intermittent malodorous discharge from the umbilicus. They had small sinus openings with hair protruding deep in the navel. Because these two patients had previous histories of failed conservative treatments, an umbilicus preserving surgery was performed for both cases. Wounds were healed in 2-3 weeks with acceptable cosmetic results. During a more than 2 year follow-up period, there were no signs of recurrence. CONCLUSIONS In a patient presenting with a history of intermittent discharge, itching, pain, or bleeding from the umbilicus and the presence of granulation tissue with or without protruding hair and periumbilical dermatitis, the diagnosis should consider UPS, even in female patients. Treatment generally depends on the severity of the disease, ranging from good personal hygiene to surgical excision of umbilical complex. The treatment of choice for chronic intermittent cases is surgical removal of the affected portion; paying special attention to cosmetic appearance.
AutoFuzz: Automated Network Protocol Fuzzing Framework

Assessing software security involves steps such as code review, risk analysis, penetration testing and fuzzing. During the fuzzing phase, the tester " s goal is to find flaws in software by sending unexpected input to the target application and monitoring its behavior. In this paper we introduce the AutoFuzz [1]-extendable, open source framework used for testing network protocol implementations. AutoFuzz is a " smart " , man-in-the-middle, semi-deterministic network protocol fuzzing framework. AutoFuzz learns a protocol implementation by constructing a Finite State Automaton (FSA) which captures the observed communications between a client and a server [5]. In addition, AutoFuzz learns individual message syntax, including fields and probable types, by applying the bioinformatics techniques of [2]. Finally, AutoFuzz can fuzz client or server protocol implementations by intelligently modifying the communication sessions between them using the FSA as a guide. AutoFuzz was applied to a variety of File Transfer Protocol (FTP) server implementations, confirming old and discovering new vulnerabilities.
A framework of fuzzy information fusion for the segmentation of brain tumor tissues on MR images

A framework of fuzzy information fusion is proposed in this paper to automatically segment tumor areas of human brain from multispectral magnetic resonance imaging (MRI) such as T1-weighted, T2-weighted and proton density (PD) images. A priori knowledge about tumors described by radiology experts for different types of MRI are very helpful to guide a automatic and a precise segmentation. However, the terminology used by radiology experts are variable in term of image signal. In order to benefit of these descriptions, we propose to modellize them by fuzzy models. One fuzzy model is built for one type of MRI sequence. The segmentation is finally based on a fusion of different fuzzy information obtained from different types of MRI images. Our algorithm consists of four stages: the registration of multispectral MR images, the creation of fuzzy models describing the characteristics of tumor, the fusion based on fuzzy fusion operators and the adjustment by fuzzy region growing based on fuzzy connecting. The comparison between the obtained results and the hand-tracings of a radiology expert shows that the proposed algorithm is efficient. An average probability of correct detection 96% and an average probability of false detection 5% are obtained through studies of four patients. q 2006 Elsevier B.V. All rights reserved.
The long and bumpy road to glass-steagall reform: A historical and evolutionary analysis of banking legislation

This paper focuses on understanding the role of interest groups and markets in influencing regulatory change. To that end, it first identifies the interest groups surrounding the creation of legislation that separated commercial and investment banking in the 1930s and then identifies the interest groups involved in the more recent attempts to repeal the separation. Careful attention is also given to developments in the private market that affect the legislative process. This then becomes the case study for understanding how interest groups and market developments are able to influence regulatory policy. This particular case study finds that existing orthodox economic and political science literature gives too much credit to interest groups and not enough credit to private market developments when analyzing policy development and reform.

The implementation of the algebra in C++ is described, and several examples illustrating the use of this software are given.
Developing L2 Oral Proficiency Through Synchronous CMC: Output, Working Memory, and Interlanguage Development

A naturalistic experiment was conducted to test the hypothesis that synchronous computer-mediated communication (CMC) can indirectly improve L2 oral proficiency by developing the same cognitive mechanisms underlying spontaneous conversational speech. The theoretical framework guiding this inquiry consists of Levelt’s (1989) model of language production augmented by concepts from Working Memory theory. The findings show a significant difference between the experimental and control groups oral proficiency development with participants in the experimental condition (two of four contact hours per week were in a chatroom) scoring higher than participants in the control condition. Implications for language instruction and the second language oral proficiency development for different types of learners are discussed.
Data Cleansing: Beyond Integrity Analysis

The paper analyzes the problem of data cleansing and automatically identifying potential errors in data sets. An overview of the diminutive amount of existing literature concerning data cleansing is given. Methods for error detection that go beyond integrity analysis are reviewed and presented. The applicable methods include: statistical outlier detection, pattern matching, clustering, and data mining techniques. Some brief results supporting the use of such methods are given. The future research directions necessary to address the data cleansing problem are discussed.
Endoscopic versus laparoscopic management of noninvasive upper tract urothelial carcinoma: 20-year single center experience.

PURPOSE
We compare the outcomes of endoscopic surgery to laparoscopic nephroureterectomy for the management of specifically noninvasive upper tract urothelial carcinoma.


MATERIALS AND METHODS
A retrospective database review identified consecutive patients with clinically noninvasive upper tract urothelial carcinoma who underwent endoscopic surgery (59, via ureteroscopic ablation or percutaneous resection) or laparoscopic nephroureterectomy (70) at a single center during 20 years (1991 to 2011). Overall survival, upper tract urothelial carcinoma specific survival, upper tract recurrence-free survival, intravesical recurrence-free survival, progression-free survival and renal unit survival were estimated using Kaplan-Meier methods, with differences assessed using the log rank test.


RESULTS
Median age and followup were 74.8 years and 50 months, respectively. Overall renal preservation in the endoscopic group was high (5-year renal unit survival 82.5%), although this came at a cost of high local recurrence (endoscopic surgery 5-year recurrence-free survival 49.3%, laparoscopic nephroureterectomy 100%, p <0.0001). For G1 upper tract urothelial carcinoma, endoscopic surgery 5-year disease specific survival (100%) was equivalent to that of laparoscopic nephroureterectomy (100%). However, laparoscopic nephroureterectomy demonstrated superior disease specific survival to endoscopic surgery for G2 disease (91.7% vs 62.5%, p = 0.037) and superior progression-free survival for G3 disease (88.9% vs 55.6%, p = 0.033).


CONCLUSIONS
For G1 upper tract urothelial carcinoma, endoscopic management can provide effective oncologic control and renal preservation. However, endoscopic management should not be considered for higher grade disease except in compelling imperative cases or in patients with poor life expectancy as oncologic outcomes are inferior to those of laparoscopic nephroureterectomy.
Energy-Efficient and Adaptive Design for Wireless Power Transfer in Electric Vehicles

Wireless power transfer (WPT) could revolutionize global transportation and accelerate growth in the electric vehicle (EV) market, offering an attractive alternative to cabled charging. Coil misalignment is inevitable due to driver parking behavior and has a detrimental effect on power transfer efficiency (PTE). This paper proposes a novel coil design and adaptive hardware to improve PTE in magnetic resonant coupling WPT and mitigate coil misalignment, a crucial roadblock in the acceptance of WPT for EVs. The new design was verified using ADS, providing a good match to theoretical analysis. Custom designed receiver and transmitter circuitry was used to simulate vehicle and parking bay conditions and obtain PTE data in a small-scale setup. Experimental results showed that PTE can be improved by 30% at the array's center, and an impressive 90% when misaligned by three-fourths of the array's radius. The proposed novel coil array achieves overall higher PTE compared to the benchmark single coil design.
Infection control knowledge and practices related to HIV among Nigerian dentists.

BACKGROUND
Many diseases including HIV/AIDS can be transmitted in the dental setting when effective infection control procedures are ignored. The aim of this study, therefore, was to evaluate the infection control knowledge and practices of Nigerian dentists in the era of HIV/AIDS.


METHODOLOGY
Information on knowledge of transmission of HIV, occupational vulnerability, infection control practices, and opinion on adequacy of infection control facilities were gathered from dentists through a self-administered questionnaire. Knowledge was assessed on a total score of 20 questions.


RESULTS
Only 3.6% of the dentists had poor knowledge. Younger males and dentists working in teaching hospitals had significantly better knowledge than their counterparts. While 40.8% believed HIV could be transmitted through saliva, only 43.2% knew it could be transmitted through the conjunctiva. Most (93.2%) wore gloves routinely and the most common barrier to glove use was non-availability. Most (79.2%) used autoclaves for sterilization; however, chemical disinfectants and boiling were also used. The majority (72.4%) believed the facilities for infection control in their centres were inadequate. Close to half of the respondents (47.6%; n = 118) rated the occupational risk of becoming infected with HIV as high.


CONCLUSION
The results of this study have shown that while the level of knowledge of the dentists was generally acceptable, there were still some misconceptions on the transmission and occupational vulnerability of HIV. It also indicates only partial compliance with recommended infection control procedures among Nigerian dentists as a result of inadequate supplies.
Cool dudes : The denial of climate change among conservative white males in the United States

We examine whether conservative white males are more likely than are other adults in the U.S. general public to endorse climate change denial. We draw theoretical and analytical guidance from the identityprotective cognition thesis explaining the white male effect and from recent political psychology scholarship documenting the heightened system-justification tendencies of political conservatives. We utilize public opinion data from ten Gallup surveys from 2001 to 2010, focusing specifically on five indicators of climate change denial. We find that conservative white males are significantly more likely than are other Americans to endorse denialist views on all five items, and that these differences are even greater for those conservative white males who self-report understanding global warming very well. Furthermore, the results of our multivariate logistic regression models reveal that the conservative white male effect remains significant when controlling for the direct effects of political ideology, race, and gender as well as the effects of nine control variables. We thus conclude that the unique views of conservative white males contribute significantly to the high level of climate change denial in the United States. 2011 Elsevier Ltd. All rights reserved.
The Other Half of the Story: Effect Size Analysis in Quantitative Research

Statistical significance testing is the cornerstone of quantitative research, but studies that fail to report measures of effect size are potentially missing a robust part of the analysis. We provide a rationale for why effect size measures should be included in quantitative discipline-based education research. Examples from both biological and educational research demonstrate the utility of effect size for evaluating practical significance. We also provide details about some effect size indices that are paired with common statistical significance tests used in educational research and offer general suggestions for interpreting effect size measures. Finally, we discuss some inherent limitations of effect size measures and provide further recommendations about reporting confidence intervals.
