Free or paid: the uses of Roses Citadel (Catalonia)
Authors: Burch Josep , Fluvià Modest , Rigall Ricard , Saló Albert , Alcalde Gabriel 
Published: September 2018

PurposeThe Roses Citadel is a bastioned fortification that has archaeological remains from the Greek, Roman and medieval periods in its interior. Currently, the area inside the Citadel is used for a wide range of activities; some directly related with the heritage item, others associated with its use as a public space for the town. The purpose of this paper is to analyse the economic interest of charging an entrance fee vs the alternative of free access and offers a framework to address this issue.Design/methodology/approachThe proposal is to consider the marginal cost of increasing the number of users and to carry out a travel cost analysis. It is vital to take into account the results of specifically economic analyses, but the evaluations of social policies should also be considered, and should have a considerable weight in decision making.FindingsIt is proposed that free entry would bring about an increase in the number of visitors and users of Roses Citadel. In turn, this increase would lead to a greater social use of this heritage asset, and a chance for the least privileged sectors of society to use the site more. Financial resources for the maintenance of the asset would not be raised through entry fees, but through contributions relating to the increase in the social consideration of the site.Originality/valueIn the context of a discussion on the advantages and disadvantages of paying an entry fee for heritage assets, the example of Roses Citadel provides several factors for consideration. It shows that payment of an entry fee affects use of the site by society, and particularly by the local community, whereas free access leads to a wide range of opportunities for use.

Authors: Deveci Muhammet , Akyurt Ibrahim Zeki , Yavuz Selahattin 
Published: September 2018

Purpose
The purpose of this paper is to present a new public bread factory location selection for Istanbul Metropolitan Municipality (IMM).

Design/methodology/approach
A two-stage methodology is proposed to determine the location for the public bread factory facility. This framework is based on both geographic information systems (GIS) and multi-criteria decision-making (MCDM) techniques. The first stage of the methodology aims to decrease the number of possible alternative locations to simplify the selection activity by applying GIS; the second stage utilises interval type-2 fuzzy MCDM approach to exactly determine the public bread factory site location.

Findings
In this study, the authors present weighted normalised-based interval type-2 hesitant fuzzy and interval type-2 hesitant fuzzy sets (IT2HFSs)-based compressed proportional assessment (COPRAS) methods to overcome facility location selection problem for a fourth public bread factory in Istanbul.

Practical implications
The results show that the proposed approach is practical and can be employed by the bakery industry.

Originality/value
In this study, the authors present a two-stage methodology for public bread factory site selection. In the first stage, the number of alternatives is reduced by the GIS. In the second stage, an interval type-2 fuzzy set is implemented for the evaluation of public bakery factory site alternatives. A new integrated approach based on COPRAS method and weighted normalised with IT2HFSs is proposed.
Analytical approach of membrane-type acoustic metamaterial with ring masses
Authors: Tian Hongyan , Tong Ding , Tao Yourui 
Published: September 2018

Purpose
Membrane-type acoustic metamaterials (MAMs) recently have been emerged to display useful sound attenuation properties in a low-frequency regime. The purpose of this paper is to present an analytical approach to investigate the transmission loss (TL) of a square membrane-ring structure of MAM. The geometrical effects of ring mass on the TL peak and dip frequencies of the MAM are obtained and discussed.

Design/methodology/approach
In this paper, based on the wave propagation and vibration theory, considering the effects of ring mass and acoustic pressure on the membrane, an analytical model is presented to analyze acoustic response of MAM.

Findings
Multiple peak frequencies and wide bandwidth appear in the membrane-ring structure, and they can be tuned by changing the location or numbers of the ring mass on the membrane. It is a useful method for designing such type of metamaterial.

Originality/value
In this paper, an analytical method is presented to evaluate the effects of ring geometric on the TL performance of square membrane-type locally resonant metamaterial. It is proved that achieving broadband and multi-peak TL profile in a single cell can indeed happen by increasing additional ring mass. The TL and frequency bandwidth can be tuned by changing the location, adding numbers and varying mass distribution of the ring masses on the membrane.
Doing good does not preclude doing well: corporate responsibility and financial performance
Authors: Lee Jegoo , Graves Samuel B. , Waddock Sandra 
Published: September 2018

PurposeThis paper aims to propose and test a modified interpretation of long-standing issues on the corporate responsibility (CR)–corporate financial performance (CFP) relationship: companies involved in CR are in general no better and no worse in their level of financial performance than companies without such engagement because of the trade-off between benefit and cost at firm level and imbalance between supply and demand at industry (market) level.Design/methodology/approachThe authors apply this frame to a data set with more than 12,000 observations over a 14-year period, using confidence intervals, as a useful and statistically valid approach for testing the null hypothesis.FindingsThe present study’s findings support neutrality between CR and CFP at the firm and industry levels, implying that a firm’s CR involvement neither penalizes nor improves its CFP.Research limitations/implicationsCR activities may provide windows of opportunity for companies but do not systematically improve financial performance.Practical implications“Doing good” is not a panacea for corporate achievement with respect to market-facing activities. For firms to succeed, instead, they need to create and implement their business cases and models by converting their involvement in CR activities into drivers for better outcomes because investments in CR practices do alone not guarantee improved financial performance.Originality/valueThe innovations in this study are twofold. Conceptually, this paper proposes a comprehensive approach for a neutral CR–CFP linkage. Empirically, it introduces a novel and appropriate method for testing neutrality. These will mark an important advance in the theoretical and empirical debates over CR and CFP.

Published: September 2018

AbstractIntroductionWell‐being is an important component of health, while informal care plays a vital role in daily care of the elderly. However, the effects of informal care on the well‐being of the elderly remain unclear. This study was aimed to estimate such effects, in which well‐being was measured by 2 subjective indicators: happiness and life satisfaction.MethodsPotential endogeneity was purified using instrumental variables. Data were collected from national baseline China Health and Retirement Longitudinal Study (CHARLS).ResultsReceiving informal care would decrease the elderly's happiness score and life satisfaction score significantly. The health produced from informal care cannot offset the health depreciation caused by aging.DiscussionTo improve the well‐being of the elderly, caregivers have more to do and policymakers can design designated care policies based on our results.
Computational fracture mechanics: An overview from early efforts to recent achievements
Authors: Sedmak Aleksandar 
Published: September 2018

AbstractAn overview of the state of the art of computational fracture mechanics is presented, starting from early efforts and going all the way up to recent achievements. Some specific aspects of linear elastic and elastic plastic fracture mechanics problems have been discussed, including the fact that even for a static loading, numerical simulation is not a simple task because of complex geometries, material nonlinearity, and heterogeneity, and especially if crack growth is considered. Therefore, micromechanical modelling of elastic‐plastic crack growth is presented as new and promising approach to overcome some of the shortages of traditional approach. Besides static loading, couple of other important practical problems are tackled, like fatigue crack growth, with remaining life in the focus of investigation, using the empirical laws for crack growth rates. Numerical simulation of fatigue crack growth is inherently complex both because of complex material damage processes and lack of sound theoretical basis to define them. Therefore, combination of theoretical, experimental, and numerical approach is presented here to get reliable and efficient estimation of life under fatigue loading.
Economic and environmental performance of miscanthus cultivated on marginal land for biogas production

Published: September 2018

AbstractEnvironmental issues surrounding conventional annual biogas crops have led to growing interest in alternative crops, such as miscanthus. In addition to the better environmental performance, miscanthus can be grown on marginal land where no competition with feed and food crops is anticipated. On marginal land however, biomass yields are significantly lower than on good agricultural land. This raises the question of the economic and environmental sustainability of miscanthus cultivated on marginal land for biogas production. This study assessed the environmental and economic performance of miscanthus cultivated on marginal land for biogas production by conducting a Life‐Cycle Assessment and complementary Life‐Cycle Cost analysis. The functional unit chosen was 1 GJ of electricity (GJel.). The substitution of a fossil reference was included using a system expansion approach. Electricity generated by the combustion of miscanthus‐based biogas in a combined heat and power has considerably lower impacts on the environment than the fossil reference in most of the categories assessed. In the impact category “climate change”, the substitution of the marginal German electricity mix leads to a carbon mitigation potential of 256 kg CO2e/GJel.. At 45.12 €/GJel., the costs of miscanthus‐based biogas generation and utilization are considerably lower than those of maize (61.30 €/GJel.). The results of this study clearly show that it can make economic and environmental sense to cultivate miscanthus on marginal land as a substrate for biogas production. The economic sustainability is however limited by the biomass yield. By contrast, there are no clear thresholds limiting the environmental performance. The decision needs to be made on a case‐by‐case basis depending on site‐specific conditions such as local biodiversity.
Patients’ experiences of coping with multiple chronic conditions: A meta‐ethnography of qualitative work
Authors: Cheng Cheng , Inder Kerry , Chan Sally Wai‐Chi 
Published: September 2018

AbstractMultiple chronic conditions (MCCs) pose a major and growing burden on the individuals’ health. The ways in which people cope with their stresses related to their chronic conditions are significant to their health outcomes. This review sought to understand lived experiences of coping with MCCs by a meta‐ethnography of qualitative studies. Twenty‐six studies were identified in four electronic databases including PubMed, PsycINFO, EMBASE, and CINAHL that were searched from 1966 to 2017. A seven‐step analytic method was used after a quality evaluation based on Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI‐QARI). The findings illustrated that experiences of coping with MCCs were interacted with (i) appraisals of MCCs, (ii) strategies to maintain a normal life, (iii) strategies to keep the spirits up, and (iv) coping in the social context. To sum up, this review provided a collection of narratives on coping with MCCs. The findings would help to recognize the high complexity experienced by these patients, also potentially offered a foundation for the design of a feasible intervention to more optimally highlight the demands of managing MCCs.
How does the smartphone usage of college students affect academic performance?
Authors: Han Sunyoung , Yi Yong Jeong 
Published: September 2018

AbstractThe present study aims to investigate the effects of smartphone use by college students on their perceived academic performance. Using five hypotheses derived from the literature related to smartphone use, the initial model was set up for path analysis to reveal the relationships among variables regarding college students' smartphone use in the academic setting. Moreover, multiple group analyses were additionally conducted to verify whether students exhibited different relationships in the hypothesized model depending on their majors. The results from path analyses showed that all path coefficients were positive and statistically significant, which indicated that all five hypothesized paths were supported. Above all, the results from multiple group analysis showed that one path (from Behavioural Intention to Use Smartphone to Academic Performance) differed significantly across groups. The findings from the current study provide educational policymakers and educators with information on how smartphone utilization in learning activities influences students' academic performance.

AbstractAims/IntroductionRisk factors of type 2 diabetes mellitus in Japanese women with recent gestational diabetes mellitus are unknown. The objective of the present study was to investigate the clinical and genetic characteristics associated with postpartum abnormal glucose tolerance in Japanese women with gestational diabetes mellitus.Materials and MethodsA total of 213 Japanese women with recent gestational diabetes mellitus who underwent a postpartum 2‐h oral glucose tolerance test were investigated. The association between antepartum clinical characteristics and postpartum abnormal glucose tolerance (diabetes or prediabetes based on the Japan Diabetes Society criteria) was examined. Frequencies of 45 known type 2 diabetes mellitus‐associated genetic variants were also compared between women with and without postpartum abnormal glucose tolerance.ResultsA total of 59 women showed postpartum abnormal glucose tolerance (prediabetes, n = 51; diabetes, n = 8). Plasma glucose levels at 1 or 2 h, the insulinogenic index and the insulin secretion‐sensitivity index‐2 of the antepartum oral glucose tolerance test were independent of postpartum abnormal glucose tolerance risk factors (P = 0.006, P = 0.00002, P = 0.01 and P = 0.006, respectively). Four genetic variants (rs266729 [ADIPOQ], rs6017317 [HNF4A], rs5215 [KCNJ11] and rs7177055 [HMG20A]) showed a nominally significant association with postpartum abnormal glucose tolerance (P < 0.05, respectively). Among these, three were related to insulin secretion. Postpartum abnormal glucose tolerance risk significantly increased with increasing risk‐allele number (P = 0.0005; odds ratio 1.91).ConclusionsClinical features and genetic variants related to impaired insulin secretion are risk factors of postpartum abnormal glucose tolerance in Japanese women with recent gestational diabetes mellitus.

AbstractTo improve the quality and functionality of emulsified surimi gels, the effect of pH and heating conditions on the properties of surimi gel fortified with fish oil was investigated. Results showed that pH conditions influenced the solubility and emulsifying properties of surimi proteins and that the gel properties were associated with the protein properties. Under direct heating, the highest gel strength was achieved at pH 8.0, in which condition the solubility was significantly higher than others. Higher emulsifying stability resulted in enhanced gel strength relative to that of the control group. However, the changes in the gel strength were not consistent under two‐step heating. In addition, the expressible moisture and oil content were found to vary depending on the pH values under both heating conditions. The corresponding changes in expressible moisture and oil content could be attributed to the high protein solubility and emulsifying properties of surimi proteins. Analysis of the dynamic rheological properties of the resulting surimi paste revealed that the gelation properties varied depending on the pH conditions during the heating process. In addition, the temperatures of myosin cross‐linking changed according to the structure of surimi proteins, which in turn varied depending on the pH conditions.Practical applicationsTo improve the functionality of surimi‐based product, the fish oil was added to prepare surimi gel. pH and heating conditions play important roles in the gelation of fish proteins. Therefore, this study investigated the effect of combined pH and heating condition on the property of surimi gel fortified with fish oil. The emulsified surimi gel with fine texture was obtained at pH of 8–8.5; moreover, heating conditions (direct heating and two‐step heating) also influenced texture of emulsified surimi gel. These results provide the evidence to produce the emulsified surimi‐based product with the high gel strength, water‐ and oil‐holding capacity.

AbstractMaternal vitamin D deficiency during pregnancy may have persistent adverse effects on childhood growth and development. We examined whether 25‐hydroxyvitamin D (25(OH)D) concentrations during pregnancy and at cord blood were associated with childhood body composition and cardiovascular outcomes. This study was embedded in a population‐based prospective cohort in Rotterdam, The Netherlands, among 4,903 mothers and their offspring. We measured 25(OH)D concentrations at a median gestational age of 20.4 weeks (95% range 18.5–23.4 weeks) and at birth (40.1 weeks [95% range 35.8–42.3 weeks]). 25(OH)D concentrations were categorized into severely deficient (<25.0 nmol/L); deficient (25.0 to 49.9 nmol/L); sufficient (50.0 to 74.9 nmol/L) and optimal (≥75.0 nmol/L). At 6 years, we measured childhood body mass index; fat and lean mass by Dual‐energy X‐ray Absorptiometry; blood pressure; and serum cholesterol, triglycerides, and insulin concentrations. Compared with children from mothers with optimal 25(OH)D concentrations (≥75.0 nmol/L), those of severely deficient vitamin D (<25.0 nmol/L) mothers had a 0.12 standard deviation score (SDS); (95% Confidence Interval (CI) [0.03, 0.21]) higher fat mass percentage and a 0.13 SDS (95% CI [−0.22, −0.04]) lower lean mass percentage. These associations remained after adjustment for current child vitamin D status. Maternal and cord blood 25(OH)D concentrations were not associated with cardiovascular risk factors in childhood. In conclusion, severe maternal 25(OH)D deficiency (<25.0 nmol/L) during pregnancy is associated with an adverse childhood body composition profile, but we did not observe evidence for an association with childhood cardiovascular risk factors. Further studies are needed to replicate our findings, to examine the underlying mechanisms, the causality of the associations, and the potential for public health interventions.

Authors: Dinh Ha , Bonner Ann , Ramsbotham Joanne , Clark Robyn 
Published: September 2018

AbstractGlobally, the increasing prevalence of heart failure is a burden on health‐care systems, especially in under‐resourced countries, such as Vietnam. We describe a prospective single‐site, cluster randomized controlled trial of an intervention designed to teach adult patients about heart failure and how to undertake self‐care activities. The intervention, delivered by a nurse, comprises of an individual teaching session using teach‐back, a heart failure booklet, weighing scales, a diary to document daily weight, and a follow‐up phone call 2 weeks after hospital discharge. Teach‐back is a process of asking patients to repeat information and for the nurse to fill any gaps or misunderstanding until adequate understanding is demonstrated. The control group will receive usual education plus the heart failure (HF) booklet. A total of 140 participants will be allocated into two study groups.The level of randomization is at the ward level. The primary outcome (HF knowledge) and secondary outcomes (self‐care behaviors and all‐cause hospitalizations) will be measured at 1 and 3 months. This study will make an important contribution regarding a protocol of teach‐back and chronic disease self‐management.

Published: September 2018

ContentsSperm vitrification as alternative to conventional freezing is increasing in popularity in many species. It has been achieved by direct exposure of diluted semen to liquid nitrogen in spheres or straws. Both techniques have been successfully developed, but they had not been compared yet in donkeys. The aim of this study was to compare these two methods of vitrification for donkey semen. Ejaculates from six Andalusian donkeys were collected and extended in Gent without glycerol supplemented with sucrose 0.1 M (Molar). Samples were slowly cooled at 5°C. For vitrification, 30 μl suspensions (spheres) were dropped directly into liquid nitrogen (LN2) or filled in covered 0.25 ml straws and then plunged into the LN2 (straws). For warming, straws and spheres were directly immersed in 3 ml of INRA‐96 at 43°C. Total (TM, %) and progressive motility (PM, %) were objectively evaluated by computer‐assisted sperm analysis and plasma membrane integrity (PMI, %) by epifluorescence microscopy. Results showed the straw method resulted in significantly higher values than spheres for: TM (54.7% ± 10.1 vs. 28.6% ± 6.5) and PM (44.2% ± 9.4 vs. 17.7% ± 6.4), but no significant differences were found between straws or spheres for PMI (31.5 ± 10.7 vs. 41.6 ± 14.3) respectively. In conclusion, donkey sperm could be vitrified in straws obtaining better sperm motility parameters after warming in comparison to the sphere method.
