Published: October 2015

[Formula: see text] (x = 0, 0.4, 0.8, 0.10, 0.12 and 0.16) samples have been synthesized by sol–gel method using polyvinyl alcohol (PVA) as chelating agent. The synthesized samples were sintered at 1000[Formula: see text]C for 1 h. The X-ray diffraction (XRD) confirms single phase spinel structure and scanning electron microscope (SEM) confirms the uniform grain with increasing grain growth with increase concentration of magnesium (Mg) (x). A slight increase in saturation magnetization (VSM) has been observed for low concentrations of magnesium which disappear for higher concentrations of magnesium [Formula: see text] in these materials. Decrease in room temperature DC resistivity with magnesium concentration has been attributed to grain growth. The permeability measured for the ferrites exhibits high permeability for increase in the magnesium content. The permeability behavior is understood on the basis of domain wall contribution and grain growth. Frequency dependence of permeability as measured suggests that the suitability of all the samples for high frequency core applications as the operating frequency lies beyond 110 MHz.

Published: October 2015

Background

Although patients with peripheral artery disease (
PAD)
are known to have an increased risk of adverse prognosis, simple techniques to further risk‐stratify
PAD
patients would be clinically useful. A plausible but unexplored factor to predict such risk would be greater disease burden, manifested as multiple lower extremity lesions. The aim of this study was to examine the association between having multiple versus isolated lower extremity PAD lesions and long‐term prognosis.

Methods and Results

A prospective cohort of 756 newly diagnosed
PAD
patients underwent duplex ultrasound testing to determine the number of lower extremity lesions. Cox regression models examined the independent association of lesion number (≥3 and 2 versus 1) and adverse prognosis (defined as a composite end point comprising first occurrence of either lower extremity amputation, admission for heart failure, nonfatal stroke, myocardial infarction, or unstable angina or mortality), adjusting for demographic and clinical risk factors. Analyses were replicated using an advanced Cox‐based model for multiple events. A total of 173 patients (23%) had ≥3 lesions, 197 (26%) had 2 lesions, and 386 (51%) had 1 lesion. After a median follow‐up of 3.2 years, patients with ≥3 lesions had an increased risk of experiencing a first adverse event (adjusted hazard ratio 1.60, 95%
CI
1.08–2.38,
P
=0.020) and an increased risk of having multiple events (adjusted hazard ratio 1.53, 95%
CI
1.08–2.18,
P
=0.018). Patients with 2 lesions had a prognosis similar to those with 1 lesion.

Conclusions

Among
PAD
patients, a greater number of lesions is associated with an increased risk of an adverse prognosis over 3 years of follow‐up. Assessing the number of lower extremity lesions might serve as a simple risk‐stratification tool at initial
PAD
diagnosis.
The Impact of Regional Arctic Sea Ice Loss on Atmospheric Circulation and the NAO
Authors: Pedersen Rasmus A. , Cvijanovic Ivana , Langen Peter L. , Vinther Bo M. 
Published: October 2015

AbstractReduction of the Arctic sea ice cover can affect the atmospheric circulation and thus impact the climate beyond the Arctic. The atmospheric response may, however, vary with the geographical location of sea ice loss. The atmospheric sensitivity to the location of sea ice loss is studied using a general circulation model in a configuration that allows combination of a prescribed sea ice cover and an active mixed layer ocean. This hybrid setup makes it possible to simulate the isolated impact of sea ice loss and provides a more complete response compared to experiments with fixed sea surface temperatures. Three investigated sea ice scenarios with ice loss in different regions all exhibit substantial near-surface warming, which peaks over the area of ice loss. The maximum warming is found during winter, delayed compared to the maximum sea ice reduction. The wintertime response of the midlatitude atmospheric circulation shows a nonuniform sensitivity to the location of sea ice reduction. While all three scenarios exhibit decreased zonal winds related to high-latitude geopotential height increases, the magnitudes and locations of the anomalies vary between the simulations. Investigation of the North Atlantic Oscillation reveals a high sensitivity to the location of the ice loss. The northern center of action exhibits clear shifts in response to the different sea ice reductions. Sea ice loss in the Atlantic and Pacific sectors of the Arctic cause westward and eastward shifts, respectively.

Purpose To explore the genetic landscape of tumors from patients enrolled on the BOLERO-2 trial to identify potential correlations between genetic alterations and efficacy of everolimus treatment. The BOLERO-2 trial has previously demonstrated that the addition of everolimus to exemestane prolonged progression-free survival by more than twofold in patients with hormone receptor–positive, human epidermal growth factor receptor 2–negative, advanced breast cancer previously treated with nonsteroidal aromatase inhibitors. Patients and Methods Next-generation sequencing was used to analyze genetic status of cancer-related genes in 302 archival tumor specimens from patients representative of the BOLERO-2 study population. Correlations between the most common somatic alterations and degree of chromosomal instability, and treatment effect of everolimus were investigated. Results Progression-free survival benefit with everolimus was maintained regardless of alteration status of PIK3CA, FGFR1, and CCND1 or the pathways of which they are components. However, quantitative differences in everolimus benefit were observed between patient subgroups defined by the exon-specific mutations in PIK3CA (exon 20 v 9) or by different degrees of chromosomal instability in the tumor tissues. Conclusion The data from this exploratory analysis suggest that the efficacy of everolimus was largely independent of the most commonly altered genes or pathways in hormone receptor–positive, human epidermal growth factor receptor 2–negative breast cancer. The potential impact of chromosomal instabilities and low-frequency genetic alterations on everolimus efficacy warrants further investigation.

Purpose In recent retrospective analyses of early-stage colorectal cancer (CRC), low and high body mass index (BMI) scores were associated with worsened outcomes. Whether BMI is a prognostic or predictive factor in metastatic CRC (mCRC) is unclear. Patients and Methods Individual data from 21,149 patients enrolled onto 25 first-line mCRC trials during 1997 to 2012 were pooled. We assessed both prognostic and predictive effects of BMI on overall survival and progression-free survival, and we accounted for patient and tumor characteristics and therapy type (targeted v nontargeted). Results BMI was prognostic for overall survival (P < .001) and progression-free survival (P < .001), with an L-shaped pattern. That is, risk of progression and/or death was greatest for low BMI; risk decreased as BMI increased to approximately 28 kg/m2, and then it plateaued. Relative to obese patients, patients with a BMI of 18.5 kg/m2 had a 27% increased risk of having a PFS event (95% CI, 20% to 34%) and a 50% increased risk of death (95% CI, 43% to 56%). Low BMI was associated with poorer survival for men than women (interaction P < .001). BMI was not predictive of treatment effect. Conclusion Low BMI is associated with an increased risk of progression and death among the patients enrolled on the mCRC trials, with no increased risk for elevated BMI, in contrast to the adjuvant setting. Possible explanations include negative effects related to cancer cachexia in patients with low BMI, increased drug delivery or selection bias in patients with high BMI, and potential for an interaction between BMI and molecular signaling pathways.
Adaptation to Information Technology: A Holistic Nomological Network from Implementation to Job Outcomes
Authors: Bala Hillol , Venkatesh Viswanath 
Published: October 2015

Information technology (IT) implementation is a major organizational change event that substantially disrupts an employee’s work environment. We develop a model of technology adaptation behaviors that employees perform to cope with a new IT that causes such disruptions. Our model posits technology adaptation behaviors as a key linking mechanism between IT implementation and employee job outcomes, thus offering a holistic nomological network of technology adaptation behaviors. Two field studies conducted over a period of six months, with four waves of data collection each, in two organizations (N = 211 and N = 181) implementing two different ITs, supported the model. We found that employees performed four different technology adaptation behaviors—exploration-to-innovate, exploitation, exploration-to-revert, and avoidance—based on whether they appraised an IT as an opportunity or a threat and whether they had perceptions of control over an IT. Employees’ experiential engagements (i.e., user participation and training effectiveness) and psychological engagements (i.e., user involvement and management support) during the implementation jointly determined their appraisal of an IT. Finally, we found that technology adaptation behaviors influenced changes in two key job outcomes, job performance and job satisfaction.

Nurses' knowledge and attitudes towards pain assessment for people with dementia in a nursing home setting
Authors: Burns Michelle , McIlfatrick Sonja 
Published: October 2015

Aim: The aim of this study was to determine nurses' knowledge and attitudes towards pain assessment for people with dementia in a nursing home setting. Background: Pain is highly prevalent among older people, yet is often under-recognised and undertreated in people with dementia. People with dementia can lose the ability to report pain and it is the role of the nurse to identify and appropriately assess pain, to provide effective treatment. This requires nurses to have sufficient knowledge and training in the assessment and management of pain in residents with dementia; however, research suggests deficits in this area. Methods: A cross-sectional survey design was used to determine nurses' knowledge and attitudes to pain assessment in dementia. A questionnaire comprising three sections was distributed to 96 registered nurses across 17 nursing homes in a health-care trust in a UK region. Results: A total of 32 responses were obtained (response rate 33%). The majority of nurses had a good knowledge in relation to the assessment and management of pain in residents with dementia. There was, however, some uncertainty among nurses over analgesic choice, the safety of opioid use in dementia, and the use of dementia-specific pain assessment tools for residents with no cognitive impairment. The main barriers to effective pain assessment for older people with dementia were workload pressures, poor staffing and lack of medical support. Conclusion: This study highlights the need to develop pain education programmes and clear guidance specifically designed for nurses caring for older people with dementia. It also emphasises the need for better communication and co-ordination of pain treatment for nursing home residents with dementia.
Clarifying the relationship between translingual practice and L2 writing: addressing learner identities
Authors: Canagarajah Suresh 
Published: October 2015

AbstractThis article re-examines the distinction between native and nonnative students that writing programs adopt in structuring their courses. It critiques the monolingual orientation based on ideologies of language ownership, homogeneity, and territoriality that this distinction is based on and develops a more expansive translingual orientation relevant to diversity in globalization and multilingualism. After articulating the changes involved in facilitating literacy acquisition, it examines the uptake of writing scholars to address their concerns. The article ends by illustrating how policy level changes can be made to accommodate the emerging orientations of translingualism by discussing how New York State secondary school teachers have implemented the Common Core State Standards.
Translanguaging and visuality: Translingual practices in literary art
Authors: Lee Tong-King 
Published: October 2015

Abstract
Translanguaging is a resource for linguistic creativity in communication and for critical engagement with one’s sociolinguistic or sociocultural reality. This article examines how translanguaging operates in two visual art installations by the contemporary Chinese artist Xu Bing. Square Word Calligraphy takes a visual turn on translanguaging by inventing a hybrid calligraphy that incorporates English words into the orthographic frame of Chinese. By physically tracing the alphabet through the character, viewers gain an embodied translingual experience, which encompasses an intercultural imaginary negotiating and transcending the English-Chinese divide. By contrast, Post Testament demonstrates an intralingual mode of translanguaging, whereby a biblical text is inflected with heterogeneous registers and rendered ineffectual as coherent discourse. Here the encounter and intertwining of text registers create a transformative space replete with ambiguity and mayhem. In these radical works of language art, translanguaging delineates borders while simultaneously interrogating them, creating liminal zones and articulating a politics of (mis)recognition, (un)readability, and (in)communicability.
Boycott or Buycott?: Internal Politics and Consumer Choices
Authors: Cuadras-Morató Xavier , Raya Josep Maria 
Published: October 2015

Abstract
Does politics affect economic relations? In particular, do political tensions significantly affect consumer choices? The main objective of the paper is to study the consequences of political conflicts between Spain and Catalonia (a region of Spain) and the subsequent boycott calls on sales of Catalan sparkling wine (cava) in the Spanish market. We use data from sales of sparkling wine in supermarkets and similar outlets. To determine with precision the boycott period we use data on the number of news on the issue that appeared in the main national Spanish daily newspapers. The results of our econometric analysis indicate that the boycott calls triggered different consumers’ reactions in different territories. While consumers in some Spanish regions followed them and reduced their purchases of Catalan cava, there was also an anti-boycott reaction of Catalan consumers which led them to increase their consumption of the product. As a consequence of this, the boycott calls had an insignificant impact at the Spanish aggregate level. These results can be rationalized by the predictions of theoretical models of boycotts that include both the free riding and animosity motives.

AbstractMid trimester fetal anatomy scan is a fundamental part of routine antenatal care. Some U/S soft markers or controversial U/S signs are seen during the scan and create some confusion regarding their relation to fetal chromosomal abnormalities. Example of these signs: echogenic focus in the heart, echogenic bowel, renal pyelectasis, ventriculomegaly, polydactely, club foot, choroid plexus cyst, single umbilical artery. We are presenting an evidence based approach from the literature for management of these controversial U/S signs.
Moving on and off the timeline in narratives of personal experience written in three languages: A form-function developmental study
Authors: Kupersmitt Judy R. 
Published: October 2015

AbstractThis paper explores the construal of temporality in personal narratives written in English, Spanish, and Hebrew, three languages that differ in their morphological marking of tense-aspect. Participants were native speakers of each language in four different age groups from middle childhood across adolescence into adulthood, so taking into account developmental facets of narrative temporality in each language. Focus is on distribution of situations on and off the timeline of the story from the point of view of the linguistic configurations employed by narrators to express the temporal domains of tense and aspect in the three languages at both the intra-clausal and inter-clausal levels. Hebrew was found to differ from Spanish and English, both of which have more enriched system of grammaticized aspect, in the distribution of situations on and off the timeline both developmentally across age groups and in the linguistic means conflated in expression of temporality. The more impoverished system of grammatical aspect in Hebrew led narrators writing in Hebrew to prefer a more linear temporal organization than their counterparts in Spanish and English. The study distinguishes between shared versus language-particular patterns of narrative-embedded temporality from the point of view of linguistic forms and their temporal functions in the context of extended discourse. Results of the study shed light on the interrelations between local linguistic means and the discourse-embedded expression of temporality in narrative development.
