Job embeddedness: a theoretical foundation for developing a comprehensive nurse retention plan.

OBJECTIVE
Using a new construct, job embeddedness, from the business management literature, this study first examines its value in predicting employee retention in a healthcare setting and second, assesses whether the factors that influence the retention of nurses are systematically different from those influencing other healthcare workers.


BACKGROUND
The shortage of skilled healthcare workers makes it imperative that healthcare providers develop effective recruitment and retention plans. With nursing turnover averaging more than 20% a year and competition to hire new nurses fierce, many administrators rightly question whether they should develop specialized plans to recruit and retain nurses.


METHODS
A longitudinal research design was employed to assess the predictive validity of the job embeddedness concept. At time 1, surveys were mailed to a random sample of 500 employees of a community-based hospital in the Northwest region of the United States. The survey assessed personal characteristics, job satisfaction, organizational commitment, job embeddedness, job search, perceived alternatives, and intent to leave. One year later (time 2) the organization provided data regarding voluntary leavers from the hospital.


RESULTS
Hospital employees returned 232 surveys, yielding a response rate of 46.4 %. The results indicate that job embeddedness predicted turnover over and beyond a combination of perceived desirability of movement measures (job satisfaction, organizational commitment) and perceived ease of movement measures (job alternatives, job search). Thus, job embeddedness assesses new and meaningful variance in turnover in excess of that predicted by the major variables included in almost all the major models of turnover.


CONCLUSIONS
The findings suggest that job embeddedness is a valuable lens through which to evaluate employee retention in healthcare organizations. Further, the levers for influencing retention are substantially similar for nurses and other healthcare workers. Implications of these findings and recommendations for recruitment and retention policy development are presented.
Feedback-Mediated Upper Extremities Exercise: Increasing Patient Motivation in Poststroke Rehabilitation

PURPOSE
This proof-of-concept study investigated whether feedback-mediated exercise (FME) of the affected arm of hemiplegic patients increases patient motivation and promotes greater improvement of motor function, compared to no-feedback exercise (NFE).


METHOD
We developed a feedback-mediated treatment that uses gaming scenarios and allows online and offline monitoring of both temporal and spatial characteristics of planar movements. Twenty poststroke hemiplegic inpatients, randomly assigned to the FME and NFE group, received therapy five days a week for three weeks. The outcome measures were evaluated from the following: (1) the modified drawing test (mDT), (2) received therapy time-RTT, and (3) intrinsic motivation inventory-IMI.


RESULTS
The FME group patients showed significantly higher improvement in the speed metric (P < 0.01), and smoothness metric (P < 0.01), as well as higher RTT (P < 0.01). Significantly higher patient motivation is observed in the FME group (interest/enjoyment subscale (P < 0.01) and perceived competence subscale (P < 0.01)).


CONCLUSION
Prolonged endurance in training and greater improvement in certain areas of motor function, as well as very high patient motivation and strong positive impressions about the treatment, suggest the positive effects of feedback-mediated treatment and its high level of acceptance by patients.

Comparison of distribution transformer losses and capacity under linear and harmonic loads

The significance of harmonics in power systems has increased substantially due to the use of solid state controlled loads and other high frequency producing devices. An important consideration when evaluating the impact of harmonics is their effect on power system components and loads. Transformers are major components in power systems. Supplying non-linear loads by transformer leads to higher losses, early fatigue of insulation, and reduction of the useful life of transformer. To prevent these problems rated capacity of transformer supplying non-linear loads must be reduced. This paper reviews the non linear loads effects on the transformers and the standard IEEE procedures for derating of the transformers which are under distorted currents. The equivalent losses and capacity of a typical 25 KVA single phase transformer is then evaluated using analysis and simulations in MATLAB/Simulink-based on useful model of transformer under harmonic condition- and results are compared.
Fibrosis in Chronic Hepatitis C Acquired in Infancy: Is It Only a Matter of Time?

OBJECTIVE:The natural history of chronic hepatitis C acquired in infancy is not well understood. The progression of fibrosis was analyzed in untreated children with chronic hepatitis C virus infection and no other hepatotoxic cofactors.METHODS:A total of 112 pediatric patients (13 with paired liver biopsies) were considered. Fibrosis was assessed by METAVIR score (i.e., stage F1 to F4). The ratio between the stage of fibrosis (METAVIR units) and the presumed duration of infection represented the “estimated” rate of fibrosis progression per year. In patients with paired biopsies, the “observed” rate of fibrosis progression was defined as the difference between the stage of fibrosis in the two biopsies divided by the time interval between them.RESULTS:Both age of patients at biopsy and duration of infection correlated with stage of fibrosis (p < 0.002 and p < 0.0005, respectively). Stage of fibrosis differed significantly between patients with infection lasting less or more than 10 yr (p < 0.0006). Sex, hepatitis C virus genotype, and route of infection did not correlate with stage of fibrosis. Among the 13 patients with paired biopsies, stage of fibrosis increased in seven and did not change in six; the median rate of estimated fibrosis progression per year was 0.142. The difference between estimated and observed fibrosis progression rates was significant (coefficient of determination, r2 = 0.031), which demonstrated that the prediction of the fibrosis progression was unreliable in 97% of patients.CONCLUSIONS:Chronic hepatitis C acquired in childhood is a progressive, slow-moving, fibrotic disease. Fibrosis progression inferred on the basis of linear mathematical models should be critically evaluated in the clinical practice.
Aprotinin decreases reperfusion injury and allograft dysfunction in clinical lung transplantation.

OBJECTIVE
Primary graft dysfunction caused by ischemia-reperfusion injury is one of the most frequent causes of early morbidity and death after lung transplantation. We hypothesized that the perioperative management with aprotinin decreases the incidence of allograft reperfusion injury and dysfunction after clinical lung transplantation.


METHODS
Lung transplant databases of two transplant centers were used to investigate the incidence of severe post-transplant reperfusion injury (PTRI). We examined data of 142 patients who underwent either single lung (81) or bilateral sequential lung (61) transplantation for COPD, idiopathic pulmonary fibrosis, cystic fibrosis, and miscellaneous lung disorders between 1997 and 2000. Thirty patients were excluded due to heart-lung transplantation or lung transplantation for Eisenmenger's disease, re-transplantation, rejection, or deviation from the standardized triple immunosuppression protocol. The data of remaining 112 patients (control group, 64% single lung, 36% sequential bilateral lung transplants) were compared to the prospectively collected data of 59 lung transplant patients over the last 5 years. All of these 59 patients were managed perioperatively with aprotinin infusion. In addition, Euro-Collins-aprotinin procurement solution (Apt-EC group) was used for 50 donor lungs (58% single lung, 42% sequential bilateral lung transplants). Aprotinin in combination with low-potassium dextran (LPD) flush solution (Apt-LPD group) was used for the procurement of 34 lungs (59% single lung, 41% sequential bilateral lung transplants). The International Society of Heart and Lung Transplantation (ISHLT) grade III injury score was used for the diagnosis of severe PTRI, which is based on a PaO(2)-FIO(2) ratio of less than 200 mmHg.


RESULTS
Severe reperfusion injury grade III was observed in 18% of the control group. ECMO support was required in 25% of these patients. The associated mortality rate was 40%. Correlating factors for PTRI were donor age greater than 35 years (45%, p=0.01, mean age 38+/-8) and recipient pulmonary artery systolic pressure greater than 60 mmHg (48%, p<0.05). Lung graft ischemic times (231+/-14 min) and intraoperative techniques (cardiopulmonary bypass in 12%) were not associated with negative outcomes. Despite longer ischemic times (258+/-36 min and 317+/-85 min, respectively) and older donors (42+/-12 years and 46+/-12 years, respectively) in the aprotinin patient groups (Apt-EC and Apt-LPD group), the incidence of PTRI was markedly lower (6% and 9%, respectively). There was no mortality in the Apt-EC group and one patient died in the Apt-LPD group due to PTRI-induced graft failure.


CONCLUSIONS
Severe PTRI increased short-term morbidity and mortality. The incidence of reperfusion injury was not dependent upon the duration of donor organ ischemia. The use of aprotinin in the perioperative patient management in lung transplantation had strong beneficial effects on the patient outcomes and decreased the incidence of post-transplant ischemia-reperfusion injury significantly.
Day-Ahead Deregulated Electricity Market Price Forecasting Using Recurrent Neural Network

This paper proposes a recurrent neural network model for the day ahead deregulated electricity market price forecasting that could be realized using the Elman network. In a deregulated market, electricity price is influenced by many factors and exhibits a very complicated and irregular fluctuation. Both power producers and consumers need a single compact and robust price forecasting tool for maximizing their profits and utilities. In order to validate the chaotic characteristic of electricity price, an Elman network is modeled. The proposed Elman network is a single compact and robust architecture (without hybridizing the various hard and soft computing models). It has been observed that a nearly state of the art Elman network forecasting accuracy can be achieved with less computation time. The proposed Elman network approach is compared with autoregressive integrated moving average (ARIMA), mixed model, neural network, wavelet ARIMA, weighted nearest neighbors, fuzzy neural network, hybrid intelligent system, adaptive wavelet neural network, neural networks with wavelet transform, wavelet transform and a hybrid of neural networks and fuzzy logic, wavelet-ARIMA radial basis function neural networks, cascaded neuro-evolutionary algorithm, and wavelet transform, particle swarm optimization, and adaptive-network-based fuzzy inference system approaches to forecast the electricity market of mainland Spain. Finally, the accuracy of the price forecasting is also applied to the electricity market of New York in 2010, which shows the effectiveness of the proposed approach.
Topology control in mobile Ad Hoc networks with cooperative communications

Cooperative communication has received tremendous interest for wireless networks. Most existing works on cooperative communications are focused on link-level physical layer issues. Consequently, the impacts of cooperative communications on network-level upper layer issues, such as topology control, routing and network capacity, are largely ignored. In this article, we propose a Capacity-Optimized Cooperative (COCO) topology control scheme to improve the network capacity in MANETs by jointly considering both upper layer network capacity and physical layer cooperative communications. Through simulations, we show that physical layer cooperative communications have significant impacts on the network capacity, and the proposed topology control scheme can substantially improve the network capacity in MANETs with cooperative communications.
Good stability but high periprosthetic bone mineral loss and late-occurring periprosthetic fractures with use of uncemented tapered femoral stems in patients with a femoral neck fracture

BACKGROUND AND PURPOSE
We previously evaluated a new uncemented femoral stem designed for elderly patients with a femoral neck fracture and found stable implant fixation and good clinical results up to 2 years postoperatively, despite substantial periprosthetic bone mineral loss. We now present the medium-term follow-up results from this study.


PATIENTS AND METHODS
In this observational prospective cohort study, we included 50 patients (mean age 81 (70-92) years) with a femoral neck fracture. All patients underwent surgery with a cemented cup and an uncemented stem specifically designed for fracture treatment. Outcome variables were migration of the stem measured with radiostereometry (RSA) and periprosthetic change in bone mineral density (BMD), measured with dual-energy X-ray absorptiometry (DXA). Hip function and health-related quality of life were assessed using the Harris hip score (HHS) and the EuroQol-5D (EQ-5D). DXA and RSA data were collected at regular intervals up to 4 years, and data concerning reoperations and hip-related complications were collected during a mean follow-up time of 5 (0.2-7.5) years.


RESULTS
At 5 years, 19 patients had either passed away or were unavailable for further participation and 31 could be followed up. Of the original 50 patients, 6 patients had suffered a periprosthetic fracture, all of them sustained after the 2-year follow-up. In 19 patients, we obtained complete RSA and DXA data and no component had migrated after the 2-year follow-up. We also found a continuous total periprosthetic bone loss amounting to a median of -19% (-39 to 2). No changes in HHS or EQ-5D were observed during the follow-up period.


INTERPRETATION
In this medium-term follow-up, the stem remained firmly fixed in bone despite considerable periprosthetic bone mineral loss. However, this bone loss might explain the high number of late-occurring periprosthetic fractures. Based on these results, we would not recommend uncemented femoral stems for the treatment of femoral neck fractures in the elderly.
Chapter 52 – 1979 Exaptations

Nearly all phenotypic features can be understood as adaptations to particular evolutionary challenges. Gould and Lewontin (1979) derisively referred to this dogma as the Panglossian paradigm of the adaptationist programme in evolutionary biology.
Management of splenic abscess: report on 16 cases from a single center.

OBJECTIVES
Splenic abscess is an uncommon disease, with a reported incidence of 0.14-0.7% in autoptic series. The best treatment option remains unclear. We report our experience of percutaneous drainage of splenic abscess under ultrasound (US) guidance.


METHODS
From 1979 to 2005, 16 consecutive patients (12 male and four female; mean age 39.9 years, range 16-72 years) were diagnosed with splenic abscess by means of US, and were treated with medical therapy alone or combined with US-guided percutaneous aspiration or catheter drainage.


RESULTS
Ten of 16 patients had bacterial abscesses (including one case of tubercular abscess), two had an amebic abscess, and four had fungal abscesses. Seven of ten patients with bacterial abscesses were successfully treated with fine needle aspiration alone, one patient was successfully treated with fine needle aspiration for one abscess and catheter drainage for another, and one patient, who subsequently required a splenectomy for an abdominal trauma, successfully underwent percutaneous catheter drainage alone. Four patients with fungal lesions were treated with medical therapy alone, and two patients later required a splenectomy. One patient with a bacterial abscess due to endocarditis was treated with medical therapy alone, and his recovery was uneventful.


CONCLUSIONS
US-guided percutaneous aspiration of splenic abscesses is a safe and effective procedure. It can be used as a bridge to surgery in patients who are critically ill or have several comorbidities. Percutaneous aspiration may allow complete non-operative healing of splenic abscesses or temporize patients at risk for surgery.

Heteropagus (parasitic) twins: a review.

Heteropagus, or "parasitic," twins are asymmetric conjoined twins in which the tissues of a severely defective twin (parasite) are dependent on the cardiovascular system of the other, largely intact twin (autosite) for survival. The estimated incidence of heteropagus twins is approximately 1 per 1 million live births. Isolated case reports comprise most of published work on this rare congenital anomaly. In the past, review articles have focused narrowly on one particular anatomical subtype of parasitic twin and/or on the anatomicopathology observed. Here, we present the epidemiology, proposed pathoembryogenic origins, anatomical abnormalities, management, and outcomes of the wide array of heteropagus twins described in the English language literature.
Charagram: Embedding Words and Sentences via Character n-grams

We present CHARAGRAM embeddings, a simple approach for learning character-based compositional models to embed textual sequences. A word or sentence is represented using a character n-gram count vector, followed by a single nonlinear transformation to yield a low-dimensional embedding. We use three tasks for evaluation: word similarity, sentence similarity, and part-of-speech tagging. We demonstrate that CHARAGRAM embeddings outperform more complex architectures based on character-level recurrent and convolutional neural networks, achieving new state-of-the-art performance on several similarity tasks. 1
Ultra-Low Power Radiation Hardened by Design Memory Circuits

A 3218 bit ultra-low power radiation-hardened by design (RHBD) register file is fabricated on a 130-nm bulk CMOS technology. Register file readout circuitry allows functionality down to . Dual interlocked cell (DICE) storage provides SEU immunity above in accelerated heavy ion testing. This memory is compared to a larger one using identical ultra low voltage circuit design techniques, but un-hardened, i.e., with conventional latch storage and using only two-edge transistor layout and no guard rings. The un-hardened ultra low voltage memory exhibits 100 lower leakage post-irradiation to 500 krad(Si), when irradiated and measured at , than when irradiated and measured with . Hence, for ultra-low power, ultra-low circuits, TID hardening techniques may be unnecessary. Read energy dissipated by the RHBD memory is 10.3 fJ per bit per operation when operated at 320 mV. The maximum operating frequency is 5 MHz at the same supply voltage.
Home blood pressure and cardiovascular outcomes in patients during antihypertensive therapy: primary results of HONEST, a large-scale prospective, real-world observational study.

UNLABELLED
This study aimed to investigate the relationship between on-treatment morning home blood pressure (HBP) and incidence of cardiovascular events using data from the Home Blood Pressure Measurement With Olmesartan Naive Patients to Establish Standard Target Blood Pressure (HONEST) study, a prospective observational study of 21 591 outpatients with essential hypertension (mean age, 64.9 years; women, 50.6%) enrolled between 2009 and 2010 at clinics and hospitals in Japan. They received olmesartan-based treatment throughout. The primary end point was major cardiovascular events. After a mean follow-up period of 2.02 years, cardiovascular events occurred in 280 patients (incidence, 6.46/1000 patient-years). The risk for the primary end point was significantly higher in patients with on-treatment morning HBP ≥145 to <155 mm Hg (hazard ratio [HR], 1.83; 95% confidence interval [CI], 1.12-2.99) and ≥155 mm Hg (HR, 5.03; 95% CI, 3.05-8.31) than <125 mm Hg and with on-treatment clinic blood pressure ≥150 to <160 mm Hg (HR, 1.69; 95% CI, 1.10-2.60) and ≥160 mm Hg (HR, 4.38; 95% CI, 2.84-6.75) than <130 mm Hg. Morning HBP associated with minimum risk was 124 mm Hg by spline regression analysis. Cardiovascular risk was increased in patients with morning HBP ≥145 mm Hg and clinic blood pressure <130 mm Hg (HR, 2.47; 95% CI, 1.20-5.08) compared with morning HBP <125 mm Hg and clinic blood pressure <130 mm Hg. In conclusion, it is essential to control morning HBP to <145 mm Hg, even in patients with controlled clinic blood pressure.

Application of wrapper approach and composite classifier to the stock trend prediction

The research on the stock market prediction has been more popular in recent years. Numerous researchers tried to predict the immediate future stock prices or indices based on technical indices with various mathematical models and machine learning techniques such as artificial neural networks (ANN), support vector machines (SVM) and ARIMA models. Although some researches in the literature exhibit satisfactory prediction achievement when the average percentage error and root mean square error are used as the performance metrics, the prediction accuracy of whether stock market goes or down is seldom analyzed. This paper employs wrapper approach to select the optimal feature subset from original feature set composed of 23 technical indices and then uses voting scheme that combines different classification algorithms to predict the trend in Korea and Taiwan stock markets. Experimental result shows that wrapper approach can achieve better performance than the commonly used feature filters, such as v-Statistic, Information gain, ReliefF, Symmetrical uncertainty and CFS. Moreover, the proposed voting scheme outperforms single classifier such as SVM, kth nearest neighbor, back-propagation neural network, decision tree, and logistic regression. 2007 Elsevier Ltd.
