Published: September 2016

PurposeThe purpose of this paper is to explore the differences in consumers’ preferences to food safety label (FSL) on vegetables in central and south central Chile in terms of sociodemographic characteristics, consumers’ food safety knowledge and frequency of vegetables consumption.Design/methodology/approachA survey was applied to 1,201 consumers in charge of buying vegetables for their households. The questionnaire measured consumer preference for FSL using tomatoes as a case study.FindingsThe most important attributes for consumers were price (57.3 percent), FSL (19.7 percent), point of sale (11.86 percent) and production system (11.07 percent). Cluster analysis was used to differentiate three types of consumers. The majority (50.5 percent) are consumers oriented to price of tomatoes more than other attributes. A second group (30.1 percent) considers it important to purchase tomatoes at the lowest price with the existence of a FSL. A minority (19.4 percent) was oriented to purchasing tomatoes with a FSL. The groups differ according to sociodemographic characteristics, food safety knowledge and frequency of vegetables consumption.Research limitations/implicationsThe study was conducted in country in South America. The results revealed that the majority of consumers choose price over FSL. Nevertheless, a potential market niche was identified that was motivated by FSL as a potential risk-reduction strategy when making choices about fresh vegetables purchase.Practical implicationsFSL is a marketing tool to help the consumers about food decisions.Social implicationsTo avoid problems associated to unsafe vegetables, FSL is used as a potential risk-reduction strategy when making choices about fresh vegetables purchase.Originality/valueThe research provides information about a market niche of consumers interested in the existence of an explicit FSL, due to their awareness of the risks associated with the consumption of vegetables. This topic has received little research in Latin American developing countries.

Published: September 2016

Purpose
Cookies were not generally viewed as functional contributors to well-being as they are primarily perceived as confectionery products. The purpose of this paper is to evaluate the potential of flaxseed-enriched cookies as carriers of lignans and omega-3 fatty acids – functional compounds that are lacking in the western diet.

Design/methodology/approach
An online questionnaire collected data from Croatian consumers (n=1,035). The majority of the samples were women (73 per cent) in the age range 15-65 years (97 per cent). Most participants were employed, had a higher education degree, and lived in urban areas. Questions examined the consumption of cookies and flaxseed, interest for functional cookies, nutritional knowledge, and awareness.

Findings
Majority of subjects consumed cookies (93 per cent), while 61 per cent did not eat flaxseed or ate it less than once a month. The consumers showed elevated interest for the functional cookies with flaxseed, among which elderly women with higher nutrition awareness, and nutrition knowledge were the most interested. Functional cookies with flaxseed could be used for delivery of lignans and omega-3 fatty acids in everyday diet, but in order to reach wider range of consumers producers might benefit from employing nutritional educational marketing campaigns.

Originality/value
Data from the study decreased scarcity of information on consumer behaviour related to flaxseed consumption and on potential use of cookies as a functional food. Reported findings will be useful to dieticians, food industry, and food researchers in countries with a high prevalence of cookie consumption.
Entrepreneurial intention in the time of crisis: a field study
Authors: Arrighetti Alessandro , Caricati Luca , Landini Fabio , Monacelli Nadia 
Published: September 2016

Purpose
The purpose of this paper is to investigate the impact of a prolonged economic recession on the entrepreneurial intentions of young people (university students) distinguishing between propensity to start a new business (i.e. degree of interest in entrepreneurship) and perceived likelihood of becoming an entrepreneur (i.e. probability to start a business in the future). Furthermore this study verifies if the recession strengthens the orientation to exploit new market opportunities, or simply supports self-employment objectives.

Design/methodology/approach
Entrepreneurial intention was measured in terms of propensity to start a new business and perceived likelihood of becoming an entrepreneur. Psychosocial and economic variables were measured as well. Information was gathered through questionnaires distributed in both electronic and paper-and-pencil form to a sample of 3,684 Italian University students enrolled in 12 different faculties.

Findings
First, this study found that while the perception of the economic crisis as an obstacle to new business creation does not impact on the propensity toward entrepreneurship, it has a negative and highly significant impact on the likelihood to start a business. Second, when a distinction is made between opportunity- and necessity-based types, results show that while for the latter the crisis impacts only on the perceived likelihood to become an entrepreneur, for the former it affects both dimensions of entrepreneurship, i.e., both propensity and perceived likelihood. Moreover, neither family support nor economic institutions are perceived as relevant in sustaining entrepreneurial intentions. On the contrary, the university is considered as a key support entity.

Research limitations/implications
Reliance on cross-sectional questionnaires instead of an experimental design imposes caution about the causal relationships between predictors and entrepreneurial intent.

Originality/value
The present paper is one of the few studies concerning the influence of rapid worsening of external economic context (severe recession) on the entrepreneurial intent.
Study of the mechanical and the thermal insulation properties of polyurethane coating containing chicken eggshell and rice husk ash as fillers
Authors: Ang Bee Chin , Ahmad Norasikin , Ong Zhi Chao , Cheok Shun Chi , Chan Hui Fen 
Published: September 2016

Purpose
The main aim of this study was to examine the effects of chicken eggshell (CES) and rice husk ash (RHA) as fillers on the mechanical and the thermal insulation properties of polyurethane coatings.

Design/methodology/approach
CES and RHA were ground via ball milling set at different parameters, and the smallest particles size obtained were selected and used as fillers. Fillers of different weight proportions were mixed with other components such as binder, solvent and pigment to form various coating formulations and test samples were made via dip coating. A series of characterisations were conducted to analyse the thermal and mechanical properties of the coating.

Findings
The smallest particle size of CES and RHA was obtained after both of them had undergone grinding process at 400 rpm within 180 min. Morphological studies revealed that CES and RHA have irregular shape and high porosity. In crystallographic analysis, CES mainly composed of pure calcite crystal structure and RHA contained amorphous silica. Both of fillers were found thermally stable up to 520 and 710°C for RHA and CES, respectively. In RHA individual system, as the RHA proportion increases, the thermal conductivity of the coating declined. In contrast, in the CES coating system, the thermal conductivity demonstrated an opposite trend. Thermal gravimetric analysis results displayed that by adding hybrid fillers, the residue weight and the thermal stability of the coatings were increased. In addition, the adhesion strength of the coating was increased as the filler weight content increased.

Research limitations/implications
Fillers with nano-range size were expected to be produced in this research for better performance of the coating. However, the obtained fillers were limited to micron size through dry grinding method. Another drawback in this research was the coating technique which is dip coating. The coated substrates do not have uniform coating thickness and this subsequently influenced the performance.

Originality/value
A novel attempt has been made to study the formulation coating system by mixing CES and RHA as fillers which is also known as a hybrid system.

Published: September 2016

Purpose
Over the past decade, the United Arab Emirates (UAE) introduced several green regulatory guidelines, federal decrees, and a considerable number of environmentally friendly initiatives. Hence, the purpose of this paper is to investigate the top green materials and systems used currently in the UAE construction industry as per the new laws dictate as well as see if professionals are switching over to incorporate more green materials, systems, and/or designs.

Design/methodology/approach
The work involved reviewing internationally popular green materials and systems for construction, developing a questionnaire based on the literature review, surveying professionals in the seven UAE emirates, and ranking the findings based on the relative importance index.

Findings
Findings found the top used green materials and system in the UAE’s construction industry. As well as identified that there is a communication gap between the design and implementation phases that is possibly hindering the use of more green materials and systems.

Originality/value
This study sets a baseline to measure the UAE’s progress over the coming years in terms of integrating more green construction materials, systems, methodologies, and trends.

ABSTRACTA novel Legionella species was identified based on sequencing, cellular fatty acid analysis, biochemical reactions, and biofilm characterization. Strain D5610 was originally isolated from the bronchial wash of a patient in Ohio, USA. The bacteria were gram‐negative, rod‐shaped, and exhibited green fluorescence under long wave UV light. Phylogenetic analysis and fatty acid composition revealed a distinct separation within the genus. The strain grows between 26–45°C and forms biofilms equivalent to L. pneumophila Philadelphia 1. These characteristics suggest that this isolate is a novel Legionella species, for which the name Legionella clemsonensis sp nov. is proposed.
The modified generalized moveout approximation: a new parameter selection
Authors: Stovas Alexey , Fomel Sergey 
Published: September 2016

ABSTRACTNon‐hyperbolic generalised moveout approximation is a powerful tool to approximate the travel‐time function by using information obtained from two rays. The standard approach for parameter selection is using three parameters defined from zero‐offset ray and two parameters obtained from a reference ray. These parameters include the travel time and travel‐time derivatives of different order. The original parameter selection implies more fit at zero offset compared with offset from a reference ray. We propose an alternative approach for parameter selection within the frame of generalised moveout approximation by transferring more fit from the zero offset to a reference ray by changing in parameter selection. The modified approximation is tested against the original one in few analytical model examples, including the multi‐layered model.

ObjectiveTo investigate the factors associated with resilience among medical professionals.Data Sources/Study SettingAdministrative information from a rural health care network (1 academic medical center, 6 hospitals, 31 clinics, and 20 school health centers) was triangulated with self‐report data from 308 respondents (response rate = 65.1 percent) to a 9/2013–1/2014 survey among practitioners serving a nine‐county 5,600‐square‐mile area.Study DesignA cross‐sectional questionnaire survey comprising valid measures of resilience, practice meaningfulness, satisfaction, and risk/uncertainty intolerance, nested within a prospective, community‐based project.Data Collection/Extraction MethodsThe sampling frame included practitioners on institutional payroll, excluding voluntary/involuntary attritions and advisory board/research team members. In multivariable mixed‐effects models, we regressed full‐range and high‐/low‐resilience scores on demographics, professional satisfaction, workplace needs, risk/uncertainty intolerance, and service unit characteristics.Principal FindingsRelational needs, uncertainty intolerance, satisfaction ≥75 percent of the time, number of practitioners on a unit, and workload were significantly associated with resilience. Higher scores were most strongly associated with uncertainty tolerance, satisfaction, and practitioner numbers. Practitioner/unit demographics were mostly nonsignificant.ConclusionsMore resilient practitioners experienced frequent satisfaction, relational needs gratification, better uncertainty tolerance, lighter workloads, and practiced on units with more colleagues. Further studies should investigate well‐being interventions based on these mutable factors.
Caloric restriction increases brain mitochondrial calcium retention capacity and protects against excitotoxicity

Published: September 2016

SummaryCaloric restriction (CR) protects against many cerebral pathological conditions that are associated with excitotoxic damage and calcium overload, although the mechanisms are still poorly understood. Here we show that CR strongly protects against excitotoxic insults in vitro and in vivo in a manner associated with significant changes in mitochondrial function. CR increases electron transport chain activity, enhances antioxidant defenses, and favors mitochondrial calcium retention capacity in the brain. These changes are accompanied by a decrease in cyclophilin D activity and acetylation and an increase in Sirt3 expression. This suggests that Sirt3‐mediated deacetylation and inhibition of cyclophilin D in CR promote the inhibition of mitochondrial permeability transition, resulting in enhanced mitochondrial calcium retention. Altogether, our results indicate that enhanced mitochondrial calcium retention capacity underlies the beneficial effects of CR against excitotoxic conditions. This protection may explain the many beneficial effects of CR in the aging brain.

Published: September 2016

AbstractAimImportant factors typically associated with prognosis in brain metastases include Karnofsky performance status (KPS), extracranial or cerebellar localization and combination chemotherapy. However, few studies investigated the prognostic role of leptomeningeal metastases (LM) following whole brain radiotherapy (WBRT). On the basis of our experience suggesting better survival of asymptomatic patients with LM than those with brain metastases, we herein evaluated LM as a prognostic factor after WBRT.MethodsMedical records of 206 patients (median age, 65 years) who received WBRT in 2007–2015 were retrospectively reviewed. The two most common cancers were of lung, breast origin in 78.5%, 10%, patients, respectively. Patients received parallel‐opposed WBRT, with a dose of 20–40 Gy. Additional doses of 9–12 Gy were used in patients who were operated on or had single metastases. Overall survival (OS) was determined, and clinical parameters including age, KPS, symptoms, radiation dose, dose per fraction, type of metastasis, extracranial metastases, primary status and surgery plus WBRT were assessed as prognostic factors.ResultsThe median survival was 6 months (range, 1–100), and 1‐ and 2‐year survival rates were 28% and 17%, respectively. In univariate analysis, improved survival was associated with KPS of ≥70, absence of symptoms, radiation dose of ≥37.5 Gy, favorable primary lesion, LM, and surgery plus WBRT. Multivariate analysis revealed that these factors with the exception of radiation dose was significant prognostic factors for OS.ConclusionWe found that LM were independent prognostic factors for good clinical outcomes.

AbstractIntroductionThe first aim of this study was to ascertain the diagnostic performance of first‐trimester ultrasound in detecting congenital anomalies in twins. The secondary aim was to explore the strength of association between different pregnancy characteristics and early detection of structural anomalies in a large unselected population of twin pregnancies. A systematic review of the published literature was also carried out.Material and methodsRetrospective analysis of prospectively collected data from consecutive twin pregnancies booked for antenatal care between 1996 and 2014. Predictive accuracy of those covariates independently associated with the occurrence of fetal anomalies was assessed with logistic regression analysis and receiver operating characteristics curves.ResultsIn all, 1064 twin pregnancies (820 dichorionic and 264 monochorionic) were included in the analysis. Forty‐two pregnancies had one or more fetuses with structural abnormalities. Detection of structural abnormalities using ultrasound was possible in the first trimester in 27.3% (95% confidence interval 15.0–42.8) of twin pregnancies. Monochorionicity (odds ratio 2.3, 95% confidence interval 1.1–4.7) and discordance in crown–rump length and nuchal translucency were associated with an increased risk of fetal anomalies. However, their predictive accuracy was only moderate (areas under the curve 0.67, 95% confidence interval 0.6–0.8 and 0.68, 95% confidence interval 0.6–0.8, for crown–rump length and nuchal translucency discrepancy, respectively).ConclusionsFirst‐trimester detection of structural abnormalities in twin pregnancies is possible in 27.3% (95% confidence interval 15.0–42.8) of cases. The likelihood for first‐trimester detection of structural anomalies in twins was maximum for cranial vault, midline brain and abdominal wall defects. Monochorionicity and increasing discrepancy in crown–rump length and nuchal translucency were associated with fetal structural abnormalities, although their predictive performance was only moderately good.
At what age does the risk for adverse maternal and infant outcomes increase? Nationwide register‐based study on first births in Finland in 2005–2014
Authors: Klemetti Reija , Gissler Mika , Sainio Susanna , Hemminki Elina 
Published: September 2016

AbstractIntroductionIt is poorly understood if there are specific ages at which adverse outcomes during pregnancy and childbirth start to increase (threshold‐ages). The purpose of this study was to examine at which maternal ages the use of maternity care and the risks for adverse maternal and infant outcomes increase.Material and methodsNational data from the Finnish Medical Birth Register including all first‐time mothers aged 20 years or over with singleton pregnancies in 2005–2014 were analyzed (n = 228 348). Odds ratios for each outcome at different ages were calculated by logistic regression, using women aged 20–24 (n = 56 282) as the reference and adjusting for socioeconomic position and urbanity of residence. The threshold‐age was defined as the first significant adjusted odds ratio after which the risk remained significant.ResultsThe threshold‐ages for use of maternity care varied from 25 years for cesarean section (OR 1.08, 95% CI 1.03–1.14) to 38 years for having 16 or more antenatal visits (1.13, 1.04–1.21). Four threshold‐ages were found for maternal health outcomes: 25 years for gestational diabetes (OR 1.15, 1.09–1.23), 27 years for placenta previa (OR 1.75, 1.11–2.75), 33 years for gestational hypertension (1.14, 1.03–1.27), and 38 years for preeclampsia (OR 1.48, 1.12–1.96). The threshold‐ages for infant health outcomes varied from 28 years for preterm birth (37 weeks, OR 1.10, 1.02–1.19) to 36 years for perinatal mortality (OR 2.10, 1.44–3.07).ConclusionsDifferent threshold‐ages were identified. Most adverse outcomes occurred earlier than the traditional cut‐off ages for high risk pregnancy, which have been set at 35 or 40 years.
Is routine transvaginal cervical length measurement cost‐effective in a population where the risk of spontaneous preterm birth is low?

Published: September 2016

AbstractIntroductionA recent meta‐analysis has suggested that routine measurement of the cervical length should be performed in conjunction with the anomaly scan to identify a group of women at increased risk of preterm delivery. We decided to investigate whether this recommendation is justifiable in a population where the risk of preterm birth is low.Material and methodsWe reviewed 12 years of obstetric data from the Coombe Women and Infants University Hospital. Relative risks of adverse outcomes from the randomized controlled trial were applied and we extrapolated the possible numbers of women requiring intervention. We then used published neonatal data to estimate the cost of neonatal care and estimated the costs of providing the service.ResultsOver 12 years from 2000 until 2011, there were 94 646 singleton deliveries, 1776 happening before 34 weeks. Spontaneous onset occurred in 882 (49.7%) of this group. These 882 births were studied. If we apply the figures from a randomized controlled trial, 1609 women (1.7% from our total population) would be expected to have a cervical length 15 mm. If we gave vaginal progesterone to all women with a sonographically short cervix, we would reduce the delivery rate before 34 weeks by 27.7%. The annual costs of providing the service were estimated to be €109 249 and the cost of immediate neonatal care was estimated to be €380 514.ConclusionGiven the implications associated with preterm delivery, routine measurement of cervical length at the time of the anomaly scan may be justifiable from a cost point of view in a population where the risk of preterm birth is low.
