Published: January 2016

AbstractHigher monetary diet cost is associated with healthier food choices and better weight management. How changes in diet cost affect changes in diet quality and weight remains unknown. The aim of this study was to assess the impact of changes in individual monetary diet cost on changes in diet quality, measured by the modified Mediterranean diet score recommendations (MDS-rec) and by energy density (ED), as well as changes in weight and BMI. We conducted a prospective, population-based study of 2181 male and female Spaniards aged between 25 and 74 years, who were followed up to the 2009–2010 academic year. We measured weight and height and recorded dietary data using a validated FFQ. Average food cost was calculated from official Spanish government data. We fitted multivariate linear and logistic regression models. The average daily diet cost increased from 3·68(SD0.0·89)€/8·36 MJ to 4·97(SD1·16)€/8·36 MJ during the study period. This increase was significantly associated with improvement in diet quality (Δ ED and Δ MDS-rec; P<0·0001). Each 1€ increase in monetary diet cost per 8·36 MJ was associated with a decrease of 0·3 kg in body weight (P=0·02) and 0·1 kg/m2 in BMI (P=0·04). These associations were attenuated after adjusting for changes in diet quality indicators. An improvement in diet quality and better weight management were both associated with an increase in diet cost; this could be considered in food policy decisions.

AbstractThere is limited evidence on the prospective association of time spent in activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) physical activity) and dietary intake with adiposity indicators in young people. This study aimed to assess associations between (1) baseline objectively measured activity intensity, dietary energy density (DED) and 4-year change in adiposity and (2) 4-year change in activity intensity/DED and adiposity at follow-up. We conducted cohort analyses including 367 participants (10 years at baseline, 14 years at follow-up) with valid data for objectively measured activity (Actigraph), DED (4-d food diary), anthropometry (waist circumference (WC), %body fat (%BF), fat mass index (FMI), weight status) and covariates. Linear and logistic regression models were fit, including adjustment for DED and moderate-to-vigorous physical activity. Results showed that baseline DED was associated with change in WC (β for 1kJ/g difference: 0·71; 95% CI 0·26, 1·17), particularly in boys (1·26; 95% CI 0·41, 2·16 v. girls: 0·26; 95% CI −0·34, 0·87), but not with %BF, FMI or weight status. In contrast, baseline SED, MPA or VPA were not associated with any of the outcomes. Change in DED was negatively associated with FMI (β for 1kJ/g increase: −0·86; 95% CI −1·59, −0·12) and %BF (−0·86; 95% CI −1·25, −0·11) but not WC (−0·27; 95% CI −1·02, 0·48). Change in SED, MPA and VPA did not predict adiposity at follow-up. In conclusion, activity intensity was not prospectively associated with adiposity, whereas the directions of associations with DED were inconsistent. To inform public health efforts, future studies should continue to analyse longitudinal data to further understand the independent role of different energy-balance behaviours in changes in adiposity in early adolescence.

AbstractThe aim of this study was to investigate the effect of providing supplementary Cr-enriched Bacillus subtilis (CEBS) to mice with regard to their growth performance, caecal microbiology, tissue Cr concentration, insulin receptor (IR) expression and plasma biochemical profile. A total of ninety-six Kunming strain mice were allocated to four different groups: control, CEBS, inorganic Cr and B. subtilis. After 15 d of treatment, mice that received CEBS or normal B. subtilis had higher body weights than control mice, and after 30 d mice given either CEBS or B. subtilis had greater body weights than control mice or those given inorganic Cr. The concentration of Cr in tissues (heart, liver, spleen, kidney and skeletal muscle) increased after CEBS supplementation. B. subtilis and CEBS supplementation caused a significant increase in the numbers of Lactobacillus and Bifidobacterium in the caecum, whereas the numbers of Escherichia coli and Staphylococcus decreased significantly compared with the control. The levels of IR RNA and protein in skeletal muscles increased significantly. Plasma glucose, total cholesterol, TAG and LDL-cholesterol levels declined significantly in the CEBS group compared with the control group, whereas plasma insulin and HDL-cholesterol levels increased significantly. In conclusion, CEBS supplementation enhanced the regulation of body growth, increased tissue organic Cr concentrations, altered caecal microbiota and enhanced IR expression to produce significant changes in plasma biochemistry.

AbstractInitial successful weight loss is often followed by weight regain after the dietary intervention. Compared with lean people, cellular stress in adipose tissue is increased in obese subjects. However, the relation between cellular stress and the risk for weight regain after weight loss is unclear. Therefore, we determined the expression levels of stress proteins during weight loss and weight maintenance in relation to weight regain. In vivo findings were compared with results from in vitro cultured human Simpson–Golabi–Behmel syndrome (SGBS) adipocytes. In total, eighteen healthy subjects underwent an 8-week diet programme with a 10-month follow-up. Participants were categorised as weight maintainers or weight regainers (WR) depending on their weight changes during the intervention. Abdominal subcutaneous adipose tissue biopsies were obtained before and after the diet and after the follow-up. In vitro differentiated SGBS adipocytes were starved for 96 h with low (0·55 mm) glucose. Levels of stress proteins were determined by Western blotting. WR showed increased expressions of β-actin, calnexin, heat shock protein (HSP) 27, HSP60 and HSP70. Changes of β-actin, HSP27 and HSP70 are linked to HSP60, a proposed key factor in weight regain after weight loss. SGBS adipocytes showed increased levels of β-actin and HSP60 after 96 h of glucose restriction. The increased level of cellular stress proteins in the adipose tissue of WR probably resides in the adipocytes as shown by in vitro experiments. Cellular stress accumulated in adipose tissue during weight loss may be a risk factor for weight regain.
Local participation and partnership development in Canada's Arctic research: challenges and opportunities in an age of empowerment and self-determination

Published: January 2016

ABSTRACTAn important component of northern research in Canada has been a strong emphasis on local participation. However, the policy and permit landscape for community participation therein is heterogeneous and presents specific challenges in promoting effective partnerships between researchers and local participants. We conducted a survey of northern research stakeholders across Canada in order better to understand the benefits and challenges associated with research partnerships with a view to informing northern research policy and practice. We found that local engagement at the proposal and research design phases, the hiring of community researchers and engagement of local persons at the results dissemination phase were important factors affecting success. Respondents also indicated a lack of social capital (trust and reciprocity) between researchers and communities as placing a negative impact on science partnerships. Overall, researchers were perceived to benefit more from research partnerships than their community counterparts. Partnerships in northern research will possibly require further decentralisation of power to achieve the policy objectives of local community participation. This could be achieved, in part, by allowing non-academic principal investigators to receive funding, or by involving communities in research priority-setting, proposal review and funding allocation processes.
Shaping nursing home mealtimes

Published: January 2016

ABSTRACTA number of studies stress the importance of positive mealtime experiences for nursing home residents. However, the components that comprise an ideal nursing home meal remain unclear, reflecting the ambiguity of whether nursing homes should be framed as institutions, domestic settings or a type of hotel. In this study, nursing home meals were viewed as situations that the involved parties could continuously modify and ‘work on’. The aim was to analyse how the staff and residents shaped mealtimes by initiating frames and acting according to established social scripts. The study was based on semi-structured interviews with staff and residents and on ethnographic data, consisting of 100 hours of observations at two nursing home settings in Sweden. The analysis revealed how staff and residents interactively shaped meals using institutional, private or restaurant frames. There were three important findings: (a) an institutional meal frame was dominant; (b) there were substantial difficulties in introducing private frames and established private scripts for meals, since such meal versions are personal and not easy to transport into collective settings; (c) successful creation of private or home-like meal situations illustrates an often overlooked skill in care work. Making meals as ‘care-free’ as possible can be viewed as a way to operationalise the goal of providing a non-institutional environment in nursing homes.
Global accountability communities: NGO self-regulation in the humanitarian sector
Authors: Zarnegar Deloffre Maryam 
Published: January 2016

AbstractHow do humanitarian non-governmental organisations (NGOs) define and institutionalise global accountability standards? This article process-traces the case of the Humanitarian Accountability Partnership-International (HAP-I), a voluntary, self-regulatory collective accountability initiative, to investigate the processes through which NGOs define collective rules, standards, and practices for accountability. This article shows the limitations of traditional representative and principal-agent models of NGO accountability when applied to the global inter-organisational realm and argues that mutual accountability better conceptualises these relationships. In this important case, the article finds that transnational coordination of NGO accountability practices results from social learning that generates a global accountability community (GAC) constituted by mutual engagement, joint enterprise, and a shared repertoire of practices. Data from the process tracing shows a collaborative not hierarchical or coercive relationship between NGOs and states, where salient donors changed their understandings and practices of accountability during the process of developing the HAP-I benchmarks. Thus, GACs both regulate the behaviour of members and constitute their social identities, interests, and practices.

AbstractWe report on the experimental observation of Smith–Purcell (SP) radiation generation by charged particle beam from laser–matter interactions. High-power laser pulses were focused onto a thin metal foil target to generate proton beams with energies up to 1.7 MeV via the target normal sheath acceleration (TNSA) process. The particle beam from the TNSA process was sent close to a periodic structure to generate SP radiation. Sub-μJ terahertz pulses were recorded using a pyroelectric detector. Simultaneous measurement of the ion spectra allowed us to estimate the power of the emitted radiation and compare it with the experimental results. The distance between the grating and the particle beam was varied and its effect on the emitted radiation was studied.

AbstractIn this study, snow particle size variability was investigated along a transect in Dronning Maud Land from the coast to the polar plateau. The aim of the study was to better understand the spatial and temporal variations in surface snow properties. Samples were collected twice daily during a traverse in 2007–08 to capture regional variability. Local variability was assessed by sampling in 10×10 m grids (5 m spacing) at selected locations. The particle size and shape distributions for each site were analysed through digital image analysis. Snow particle size variability is complex at different scales, and shows an internal variability of 0.18–3.31 mm depending on the sample type (surface, grid or pit). Relationships were verified between particle size and both elevation and distance to the coast (moisture source). Regional seasonal changes were also identified, particularly on the lower elevations of the polar plateau. This dataset may be used to quantitatively analyse the optical properties of surface snow for remote sensing. The details of the spatial and temporal variations observed in our data provide a basis for further studies of the complex and coupled processes affecting snow particle size and the interpretation of remote sensing of snow covered areas.
‘Your Salvation is the Struggle Against Fascism’: Yugoslav Communists and the Rescue of Jews, 1941–1945
Authors: KERENJI EMIL 
Published: January 2016

AbstractThis article recounts a little-known episode in which Yugoslav partisans, led by the Communist Party of Yugoslavia, rescued some 2,500 Jews from the former Italian camp for Jews in the northern Adriatic in the autumn of 1943. By focusing on this historical event, the article argues for broadening the notion of rescue of Jews during the Holocaust. Rather than locating ‘rescue’ in the motivations of individuals, the article takes as a point of departure the collective aspect of rescue and investigates the importance of the ideological considerations of the Communist Party of Yugoslavia in its decision to rescue the Jews. Rather than in abstract ethical notions, the partisan rescue of the Jews was rooted in their political vision of the future socialist federation, of which the Jews were part.

AbstractIntroductionUsing the Medical Priority Dispatch System (MPDS) – a systematic 911 triage process – to identify a large subset of low-acuity patients for secondary nurse triage in the 911 center is a largely unstudied practice in North America. This study examines the ALPHA-level subset of low-acuity patients in the MPDS to determine the suitability of these patients for secondary triage by evaluating vital signs and necessity of lights-and-siren transport, as determined by attending Emergency Medical Services (EMS) ambulance crews.ObjectivesThe primary objective of this study was to determine the clinical status of MPDS ALPHA-level (low-acuity) patients, as determined by on-scene EMS crews’ patient care records, in two US agencies. A secondary objective was to determine which ALPHA-level codes are suitable candidates for secondary triage by a trained Emergency Communication Nurse (ECN).MethodsIn this retrospective study, one full year (2013) of both dispatch data and EMS patient records data, associated with all calls coded at the ALPHA-level (low-acuity) in the dispatch protocol, were collected. The primary outcome measure was the number and percentage of ALPHA-level codes categorized as low-acuity, moderate-acuity, high-acuity, and critical using four common vital signs to assign these categories: systolic blood pressure (SBP), pulse rate (PR), oxygen saturation (SpO2), and Glasgow Coma Score (GCS). Vital sign data were obtained from ambulance crew electronic patient care records (ePCRs). The secondary endpoint was the number and percentage of ALPHA-level codes that received a “hot” (lights-and-siren) transport.ResultsOut of 19,300 cases, 16,763 (86.9%) were included in the final analysis, after excluding cases from health care providers and those with missing data. Of those, 89% of all cases did not have even one vital sign indicator of unstable patient status (high or critical vital sign). Of all cases, only 1.1% were transported lights-and-siren.ConclusionWith the exception of the low-acuity, ALPHA-level seizure cases, the ALPHA-level patients are suitable to transfer for secondary triage in a best-practices, accredited, emergency medical dispatch center that utilizes the MPDS at very high compliance rates. The secondary nurse triage process should identify the few at-risk patients that exist in the low-acuity calls.ScottG, ClawsonJ, FivazMC, McQueenJ, GardettMI, SchultzB, YoungquistS, OlolaCHO.

Photoluminescence Studies of Both the Neutral and Negatively Charged Nitrogen-Vacancy Center in Diamond

Published: January 2016

AbstractIn this study low temperature micro-photoluminescence technology was employed to investigate effects of the irradiation and nitrogen concentration on nitrogen-vacancy (NV) luminescence, with the photochromic and vibronic properties of the NV defects. Results showed that the NV luminescence was weakened due to recombination of self-interstitials created by electron irradiation in diamond and the vacancies within the structure of NV centers. For very pure diamond, the vacancies migrated the long distance to get trapped by N atoms only after sufficient high temperature annealing. As with the increase in nitrogen content, the migration distance of vacancies got smaller. The nitrogen also favored the formation of negatively charged NV centers with the donating electrons. Under the high-energy ultraviolet laser excitation, the photochromic property of the NV− center was also observed, though it was not stable. Besides, the NV centers showed very strong broad sidebands, and the vibrations involved one phonon with energy of ~42 meV and another with ~67 meV energy.
Fractal and Lacunarity Analyses: Quantitative Characterization of Hierarchical Surface Topographies

Published: January 2016

AbstractBiomimetic hierarchical surface structures that exhibit features having multiple length scales have been used in many technological and engineering applications. Their surface topographies are most commonly analyzed using scanning electron microscopy (SEM), which only allows for qualitative visual assessments. Here we introduce fractal and lacunarity analyses as a method of characterizing the SEM images of hierarchical surface structures in a quantitative manner. Taking femtosecond laser-irradiated metals as an example, our results illustrate that, while the fractal dimension is a poor descriptor of surface complexity, lacunarity analysis can successfully quantify the spatial texture of an SEM image; this, in turn, provides a convenient means of reporting changes in surface topography with respect to changes in processing parameters. Furthermore, lacunarity plots are shown to be sensitive to the different length scales present within a hierarchical structure due to the reversal of lacunarity trends at specific magnifications where new features become resolvable. Finally, we have established a consistent method of detecting pattern sizes in an image from the oscillation of lacunarity plots. Therefore, we promote the adoption of lacunarity analysis as a powerful tool for quantitative characterization of, but not limited to, multi-scale hierarchical surface topographies.
Pension reform in a worst case scenario: public finance versus political feasibility

Published: January 2016

AbstractThis paper uses a quantitative overlapping generation model to suggest a pension reform able to sustain a retirement system, in the face of deep demographic changes. We derive the reform design from an optimization program that selects one or more policy instruments – and their values – among a predefined set, to minimize the welfare loss of the median voter while keeping sound public finances, sustaining gross domestic product growth and considering the welfare of the newborn generation. We calibrate the model to the Luxembourg economy. The European Commission (2012) forecasts that, among all euro area countries, Luxembourg will experience the largest increase in pension costs between now and 2060. Our simulations show that a single instrument reform would imply severe backlashes on the rest of the economy. The suggested pension reform instead consists of a policy mix including taxation, benefits and the effective retirement age. We stress the need to design pension reforms based on optimization programs that lead to the achievement of desired targets. Indeed, the reform implemented by the Luxembourg government in 2013, which does not result from an optimization program, will not keep public finances sound over the medium term.
