Is it simpler to leave or to stay put? Desired immobility in a Mexican village
Authors: Mata‐Codesal Diana 
Published: December 2017

AbstractThis paper ethnographically explores particular ways of staying put in a Mexican village that builds upon a myriad of present and past mobilities. By doing so, the research contributes to open the black box of rural immobility. Three broad types of stayers are identified: desired, acquiescent, and involuntary stayers. The ethnographic material supports the explanatory power of breaking down the aspiration phase from the realisation one to understand the (mis)matching between desires and capacities for situations of permanence. The research particularly explores how villagers willing to remain, have managed to stay put in a context of high physical mobility, and how staying villagers perceive the desirability and feasibility of staying put compared with that of migrating. Staying put, similarly to migration, is often part of complex life strategies that involve changing mobility–immobility articulations. In the particular ethnographic context, staying put is ascribed an intrinsic positive value. Migration (whether internal or international) has an instrumental value as the means to be able to remain in the village.
The Interplay of Product Involvement and Sustainable Consumption: An Empirical Analysis of Behavioral Intentions Related to Green Hotels, Organic Wines and Green Cars
Authors: Rahman Imran 
Published: December 2017

AbstractPrior research has not fully shown how type and level of product involvement can have different effects on behavioral intentions regarding different green products. The purpose of this study is to examine how consumer involvement affects purchase intentions, willingness to pay more and willingness to sacrifice for three green products – green hotels, organic wines and green cars. By applying consumer involvement and elaboration likelihood theory, this study investigates whether significant differences exist between high‐ and low‐involvement consumers' behavioral intentions for these three environmental products. Results reveal that consumers' behavioral intentions depend strongly on the type of environmental product considered and the underlying type and extent of involvement associated with the product category. As products can be distinctly different depending on the associated involvement, consumption dynamics and attributes, it is important for marketers to take note of the differences when designing marketing campaigns for green products.

Published: December 2017

The sputtering of bismuth (Bi/Si) thin films deposited onto silicon substrates and irradiated by swift Cuq+ heavy ions (q = +4 to +7) was investigated by varying both the ion energy over the 10 to 26‐MeV range and the ion fluence ϕ from 5.1 × 1013 cm−2 to 3.4 × 1015 cm−2. The sputtering yields were determined experimentally via the Rutherford backscattering spectrometry technique using a 2‐MeV He+ ion beam. The measured sputtering yields versus Cu7+ ion fluence for a fixed incident energy of 26 MeV exhibit a significant depression at very low ϕ‐values flowed by a steady‐state regime above ~1.6 × 1014 cm−2, similarly to those previously pointed out for Bi thin films irradiated by MeV heavy ions. By fixing the incident ion fluence to a mean value of ~2.6 × 1015 cm−2 in the upper part of the yield saturation regime, the measured sputtering yield data versus ion energy were found to increase with increasing the electronic stopping power in the Bi target material. Their comparison to theoretical predicted models is discussed. A good agreement is observed between the measured sputtering yields and the predicted ones when considering the contribution of 2 competitive processes of nuclear and electronic energy losses via, respectively, the SRIM simulation code and the inelastic thermal spike model using refined parameters of the ion slowing down with reduced thermophysical proprieties of the Bi thin films.

AbstractHybrid halide perovskite is one of the promising light absorber and is intensively investigated for many optoelectronic applications. Here, the first prototype of a self‐powered inorganic halides perovskite for chemical gas sensing at room temperature under visible‐light irradiation is presented. These devices consist of porous network of CsPbBr3 (CPB) and can generate an open‐circuit voltage of 0.87 V under visible‐light irradiation, which can be used to detect various concentrations of O2 and parts per million concentrations of medically relevant volatile organic compounds such as acetone and ethanol with very quick response and recovery time. It is observed that O2 gas can passivate the surface trap sites in CPB and the ambipolar charge transport in the perovskite layer results in a distinct sensing mechanism compared with established semiconductors with symmetric electrical response to both oxidizing and reducing gases. The platform of CPB‐based gas sensor provides new insights for the emerging area of wearable sensors for personalized and preventive medicine.

Published: December 2017

AbstractCarbon‐supported nickel selenide (Ni0.85Se/C) hollow nanowires are prepared from carbon‐coated selenium nanowires via a self‐templating hydrothermal method, by first dissolving selenium in the Se/C nanowires in hydrazine, allowing it to diffuse out of the carbon layer, and then reacting with nickel ions into Ni0.85Se nanoplates on the outer surface of the carbon. Ni0.85Se/C hollow nanowires are employed as anode materials for sodium‐ion batteries, and their electrochemical performance is evaluated via the cyclic voltammetry and electrochemical impedance spectroscopy combined with ex situ X‐ray photoelectron spectroscopy and X‐ray diffraction measurements. It is found that Ni0.85Se/C hollow nanowires exhibit greatly enhanced cycle stability and rate capability as compared to Ni0.85Se nanoparticles, with a reversible capacity around 390 mA h g−1 (the theoretical capacity is 416 mA h g−1) at the rate of 0.2 C and 97% capacity retention after 100 cycles. When the current rate is raised to 5 C, they still deliver capacity of 219 mA h g−1. The synthetic methodology introduced here is general and can easily be applied to building similar structures for other metal selenides in the future.

Published: December 2017

AbstractNanostructured materials make a considerable impact on the performance of lithium‐storage characteristics in terms of the energy density, power density, and cycle life. Direct experimental observation, by a comparison of controlled nanostructural uniformity of electrode materials, reveals that the lithium‐storage behaviors of mesoporous MoO2 and CuO electrodes are linearly correlated with their nanostructural uniformity. Reversible capacities of mesoporous MoO2 and CuO electrodes with well‐developed nanostructures (1569 mA h g−1 for MoO2 and 1029 mA h g−1 for CuO) exceed their theoretical capacity based on the conversion reaction (838 mA h g−1 for MoO2 and 674 mA h g−1 for CuO). Given that exact understanding of the origin of the additional capacity is essential in maximizing the energy density of electrode material, this work may help to gain some insights into the development of high energy‐density lithium‐storage materials for next‐generation lithium rechargeable batteries.

Published: December 2017

AbstractThe delivery of tumor‐suppressive noncoding RNAs (ncRNAs) including short ncRNAs (i.e., miRNAs) and long ncRNAs (lncRNAs) is put forward to treat tumors. In this work, novel rodlike supramolecular nanoassemblies (CNC @CB[8] @ PGEA) of degradable poly(aspartic acid) (PAsp) derivatives‐grafted cellulose nanocrystals (CNCs) and hydroxyl‐rich polycations (ethanolamine‐functionalized poly(glycidyl methacrylate), PGEA) are proposed via typical cucurbit[8]uril (CB[8])‐based host–guest interactions for delivery of different ncRNAs to treat hepatocellular carcinoma (HCC). Spindly CNCs, one kind of natural polysaccharide nanoparticles, possess good biocompatibility and unique physico‐chemical properties. PGEA with abundant hydroxyl groups is one promising gene carrier with low cytotoxicity. PAsp can benefit the disassembly and degradability of nanoassemblies within cells. CNC @ CB[8]@PGEA combines the different unique properties of CNC, PGEA, and PAsp. CNC @ CB[8] @ PGEA effectively complexes the expression constructs of miR‐101 (plasmid pc3.0‐miR‐101) and lncRNA MEG3 (plasmid pc3.0‐MEG3). CNC @ CB[8] @ PGEA produces much better transfection performances than PGEA‐containing assembly units. In addition, the codelivery system of CNC @ CB[8] @ PGEA/(pc3.0‐MEG3+pc3.0‐miR‐101) nanocomplexes demonstrates better efficacy in suppressing HCC than CNC @ CB[8] @ PGEA/pc3.0‐MEG3 or CNC @ CB[8] @ PGEA/pc3.0‐miR‐101 nanocomplexes alone. Such rodlike supramolecular nanoassemblies will provide a promising means to produce efficient delivery vectors of versatile tumor‐suppressive nucleic acids.

Published: December 2017

AbstractHerein, the hydrothermal synthesis of porous ultrathin ternary NiFeV layer double hydroxides (LDHs) nanosheets grown on Nickel foam (NF) substrate as a highly efficient electrode toward overall water splitting in alkaline media is reported. The lateral size of the nanosheets is about a few hundreds of nanometers with the thickness of ≈10 nm. Among all molar ratios investigated, the Ni0.75Fe0.125V0.125‐LDHs/NF electrode depicts the optimized performance. It displays an excellent catalytic activity with a modest overpotential of 231 mV for the oxygen evolution reaction (OER) and 125 mV for the hydrogen evolution reaction (HER) in 1.0 m KOH electrolyte. Its exceptional activity is further shown in its small Tafel slope of 39.4 and 62.0 mV dec−1 for OER and HER, respectively. More importantly, remarkable durability and stability are also observed. When used for overall water splitting, the Ni0.75Fe0.125V0.125‐LDHs/NF electrodes require a voltage of only 1.591 V to reach 10 mA cm−2 in alkaline solution. These outstanding performances are mainly attributed to the synergistic effect of the ternary metal system that boosts the intrinsic catalytic activity and active surface area. This work explores a promising way to achieve the optimal inexpensive Ni‐based hydroxide electrocatalyst for overall water splitting.
Experiments in systems engineering and design research

Published: December 2017

AbstractControlled experiments ranging from laboratory experiments to field experiments are becoming increasingly important within systems engineering and design (SE&D) research. Controlled experiments provide unique capabilities for testing hypotheses, and guiding the development of scientific theories, but their potential is not being fully exploited. As the systems engineering research community embraces different research methods commonly adopted in other domains, there is a need for understanding the role and appropriateness of those methods within the research process. While the design of experiments in SE&D research is not unique per se, we contend that aspects of representativeness in the SE&D context pose different experimental design challenges than do the problems typically studied by experimental social scientists. There is therefore a need to translate established practices to the SE&D context, and also belay widely held concerns about the value of experiments in SE&D research. To address this need, the goals of the paper are to discuss the potential role of controlled experiments in systems engineering and design research, to review the benefits and limitations of different types of experiments, and to highlight the key issues in validating experimental studies. The taxonomy and the discussion on validation build on the rich history in social and behavioral sciences, with specific adaptation to the SE&D context. The discussion is anchored in specific examples from the authors’ own research on open innovation in systems engineering.

Published: December 2017

AbstractBackgroundPre‐operative fasting leads to insulin resistance and increased metabolic stress in non‐diabetic patients. Consumption of a carbohydrate drink may alleviate these deleterious effects. Patients with diabetes mellitus represent over 15% of the surgical population, yet concerns over hyperglycemia and aspiration have excluded patients with diabetes mellitus from studies assessing the utility of pre‐operative carbohydrate drinks.ObjectiveTo assess for a clinically significant increase in pre‐operative blood glucose concentration (defined as >2 mmol/L) in patients with diabetes consuming a pre‐operative carbohydrate drink.MethodsA prospective observational non‐inferiority cohort study of 106 subjects with diabetes mellitus was undertaken to assess the effect of consuming a pre‐operative carbohydrate drink in surgical patients. All patients with diabetes mellitus undergoing surgery (including but not limited to cardiac, neurologic, urologic, and general surgical procedures) were enrolled. Subjects were instructed to consume two carbohydrate‐rich drinks, one before sleeping the evening prior to surgery and another on the day of surgery.ResultsIn total, 43% of subjects were fully compliant with the pre‐operative carbohydrate drink regimen. There were no significant differences between the fully compliant and non‐compliant subjects with respect to baseline characteristics. Consumption of a pre‐operative carbohydrate drink was determined to be non‐inferior to fasting in terms of pre‐operative blood glucose concentration (absolute difference 0.23 mmol/L, 95% CI: −1.00 to 1.45 mmol/L, pnon‐inferiority < 0.01). Neither group was found to be superior in terms of pre‐operative blood glucose concentration, hyperglycemia, or length of stay.ConclusionsThese findings function as a step toward ensuring pre‐operative carbohydrate drinks are safe in patients with diabetes undergoing surgery.

Published: December 2017

AbstractBackgroundTumor recurrence during the first year after oncological esophagectomy has been reported in up to 17–66% of patients. However, little is known as to the risk factors potentially associated with this adverse outcome. The aim of this retrospective observational study was to identify clinically relevant parameters associated with early recurrence.MethodsAll patients with squamous cell cancer or adenocarcinoma of the esophagus or gastroesophageal junction, operated with curative intent in our center from 2000 to 2014, were screened for this study. Univariate analysis was conducted to identify variables potentially associated with early recurrence, and clinically relevant parameters with P < 0.1 were included in multiple logistic regression. Survival analyses were conducted with the Kaplan–Meier method. Significance threshold was set at P < 0.05.ResultsAmong the 164 included patients, 46 (28%) presented early recurrence. Eight patients (17.4%) had locoregional and 38 patients (82.6%) metastatic recurrence. Advanced T and N stages, lymph node capsular effraction, a high positive‐to‐resected lymph node ratio, positive resection margins, poor response to neoadjuvant treatment, preoperative active smoking, malnutrition and dysphagia were associated with early recurrence on a univariate level. In multivariable analysis, preoperative smoking (OR 2.76, 95% CI 1.28–6.17), pT stage (OR 1.72, 95% CI 1.18–2.58) and an increased positive‐to‐resected lymph node ratio (OR 6.72, 95% CI 1.08–48.51) remained independently associated with ER.ConclusionOur study identified both patient‐ and tumor‐related parameters as risk factors for early recurrence after oncological esophagectomy. Of particular interest, active smoking was significantly associated with this adverse outcome, highlighting the importance of preoperative smoking cessation.
Can Increased Educational Attainment Among Lower-Educated Mothers Reduce Inequalities in Children’s Skill Development?
Authors: Augustine Jennifer March , Negraia Daniela V. 
Published: December 2017

Abstract
A rich tradition of stratification research has established a robust link between mothers’ education and the skills in children that forecast children’s own mobility. Yet, this research has failed to consider that many U.S. women are now completing their education after having children. Such a trend raises questions about whether increases in mothers’ educational attainment can improve their children’s skill development and whether these gains are enough to reduce inequalities in skills compared with children whose mothers completed the same degree before they were born. To answer these questions, we draw on a nationally representative sample of mothers and children participating in the National Longitudinal Surveys (NLSY79 and CNLY), random- and fixed-effects techniques, and repeated measures of children’s cognitive and noncognitive skills. Contrary to existing research and theory, our results reveal that educational attainment obtained after children’s births is not associated with an improvement in children’s skills. Such findings offer substantial refinement to a long-standing model of intergenerational mobility by suggesting that the intergenerational returns to mother’s education are weaker when education is acquired after children are born. Results also highlight the limits of two-generation policy approaches to reducing inequality in future generations.

AbstractIntroductionIncreased hospitalization is a major component of dementia impact on individuals and cost, but has rarely been studied in dementia with Lewy bodies (DLB). Our aim was to describe the risk and duration of hospital admissions in patients with DLB, and compare these to those in Alzheimer's disease (AD) and the general population.MethodsA large database of mental health and dementia care in South London was used to assemble a cohort of patients diagnosed with DLB. These were 1:4 matched with patients diagnosed with AD on age, gender, and cognitive status.ResultsRates of hospital admissions in the year after dementia diagnosis were significantly higher in 194 patients with DLB than in 776 patients with AD (crude incidence rate ratio 1.50; 95% confidence interval: 1.28–1.75) or the catchment population (indirectly standardized hospitalization rate 1.22; 95% confidence interval: 1.06–1.39). Patients with DLB had on average almost four additional hospital days per person‐year than patients with AD. Multivariate Poisson regression models indicated poorer physical health early in the disease course as the main driver of this increased rate of hospitalization, whereby neuropsychiatric symptoms additionally explained the higher number of hospital days.DiscussionPatients with DLB are more frequently admitted to general hospitals and utilize inpatient care to a substantially higher degree than patients with AD or the general elderly population. These data highlight an opportunity to reduce hospital days by identifying DLB earlier and providing more targeted care focused on the specific triggers for hospitalization and associations of prolonged stay.

AbstractIntroductionTo improve the detection of changes in Alzheimer's disease (AD), we designed the cognitive‐functional composite (CFC). As a first validation step, we investigated its test–retest reliability and feasibility of use.MethodsWe performed a test–retest study with 2–3 weeks between assessments, including patients with mild cognitive impairment (MCI) or mild AD dementia and cognitively healthy participants. We calculated intraclass correlation coefficients (ICCs) type absolute agreement for all CFC measures and compared baseline and retest scores using paired‐samples t‐tests. We evaluated feasibility by interviewing participants.ResultsForty‐three patients (40% female, mean age = 69.9) and 30 controls (50% female, mean age = 65) were included. Subtest intraclass correlation coefficients ranged from .70 to .96. We found negligible improvements after retesting on only two subtests. Overall, patients perceived the administration of the CFC as feasible.DiscussionThe CFC is a stable and feasible measure in MCI and mild AD dementia, and thereby meets important quality metrics for clinically meaningful outcome measures.
