Evaluating the nutritional and sensory quality of bread, cookies and noodles made from wheat supplemented with root tuber flour
Authors: Dankwa Kwame Obeng , Liu Yu-Jiao , Pu Zhi-En 
Published: March 2017

Purpose
Due to the rise in urbanization, demand for easily prepared foods such as pastries and noodles has risen. But the high price of wheat in the global market puts financial stress on low-income people, especially on those living in tropical regions, where wheat does not thrive well. They depend solely on imported wheat, which is expensive due to importation cost, or seek other relatively less-nutritious cereals. Therefore the purpose of this paper is to investigate the possibility of supplementing wheat flour with flour from relatively cheap and easy-to-produce root tuber, such as cassava, potato and sweet potato.

Design/methodology/approach
Strong-, medium- and weak-gluten wheat flours were supplemented with flour from cassava, potato and sweet potato at 10, 20 and 30 percent. Strong gluten composites were used to make bread, whereas medium and weak gluten composites were used for cookie and noodle production, respectively. Protein, ash, fat, crude fiber, moisture, carbohydrate, gluten, zeleny and energy contents of each composite were tested.

Findings
The nutritional and sensory quality of bread, cookies and noodles made from wheat flour supplemented with root tuber flour at 10, 20 and 30 percent was assessed. Results revealed that mixing wheat flour and root tuber flour has important effects on the moisture, protein, carbohydrate, fat, ash, gluten, zeleny sedimentation value and crude fiber content of the resulting mixture. Moisture and carbohydrate increased while protein and fat significantly (p<0.05) decreased with increasing root tuber flour levels in formulations. Gluten content also decreased significantly with rising root tuber flour concentrations. There was a mild reduction in bread’s general acceptability at 10 and 20 percent in potato composites; thus potato flour was still acceptable at 20 percent. Cassava flour composite also topped with a general acceptability score of 69.26 at 20 percent in cookies, whereas sweet potato composite achieved a score of 84.81 in noodles.

Originality/value
This work has successfully confirmed that wheat flour could be supplemented up to 20 percent with root tuber flour without compromising the nutritional and sensory quality of products. It has also demonstrated that different products require different root tuber flour substitution for optimum results. Potato at 10 percent substitution was found to be best for bread production. Cassava and sweet potato at 10 percent substitution were also best for cookies and noodles, respectively. With respect to protein content only, sweet potato substitution is better than cassava and potato.
Gaining insights into the measurement of value in industrial service network
Authors: Saunila Minna , Rantala Tero , Ukko Juhani , Pekkola Sanna 
Published: March 2017

Purpose
Nowadays, maintenance companies form networks, where multiple organizations and actors can deliver value to the customers. Current literature does not take into account how the value created by the entire network can be measured. The purpose of this paper is to address this research gap by identifying how the value created by the maintenance network as well as the participating individual organization can be measured simultaneously.

Design/methodology/approach
The research has been carried out using the qualitative research approach. The findings of the study are based on literature search as well as research processes carried out in two maintenance service networks.

Findings
The study presents a framework and propositions on how to measure network value in maintenance services. According to the results, the network value can be measured from the following five perspectives: financial capital, i.e., savings or growth; end customer capital such as the end customer satisfaction and recommending customers; network capital, i.e., know-how development and learning; sustainable capital such as business continuity and environmental safety; and relationship capital, such as reputation and new contacts.

Originality/value
Despite the increasing amount of literature on performance measurement in networks, theory is still lacking that reflects the complexity and dynamism when value is delivered to customers through maintenance networks. Significant novelty of the research is based on combining network, service, and value perspectives in performance measurement.
Safety management system in automotive and energy industries
Authors: Phusavat Kongkiti , Vongvitayapirom Bordin , Kess Pekka , Lin Binshan 
Published: March 2017

Purpose
The purpose of this paper is to report the key results and lessons of a study in Thailand. Occupational safety and health is the foundation of ISO 26000, which emphasizes on corporate social responsibility. This study underlines the needs on gradually preparing the industries for market integration.

Design/methodology/approach
Two leading companies in automotive and energy industries are selected. The automotive industry is one of Thailand’s largest clusters in terms of investment, employment, and sale turnovers. On the other hand, the energy industry is critical as Thailand seeks to import energies from neighboring and other countries. The in-depth analysis aims to identify excellent practices, elements, and success factors commonly shared by the two selected companies. The interviews with the companies’ executives follow this identification for the findings’ confirmation and possible extension.

Findings
The findings provide a description of the process of how an integrated safety management system is implemented and reports results such as the following. The two leading companies apparently share many common practices, elements, and success factors. They include safety culture (empowerment, behavior, communication, etc.), system and structure (processes, instruction, documentations, records, etc.), and use of external influences (e.g. safety audits by international partners and customers) to sustain the safety management system.

Originality/value
This study should inform executives and managers who are concerned with how to prepare an organization when attempting to adapt to Occupational Health and Safety Management Systems 18000 and subsequently to ISO 26000. Building a strong safety culture should be considered as the foundation, while relying on regulatory compliance and enforcement alone is not adequate.
Perceived quality of administrative services and its consequences on students’ behavioral intentions
Authors: Al-Kilani Mohammad Hani , Twaissi Naseem 
Published: March 2017

Purpose
This study aims to assess students’ perceived quality of university administrative services, and reconnoiter the disparities in their perceptions according to their gender and college. This study also scrutinizes the influences of students’ perceived quality of university administrative services on their behavioral intentions, and examines the moderating effects of students’ gender on these influences.

Design/methodology/approach
Achieving a reply rate of 68 per cent, this study was carried out in a public university in Jordan by using a stratified systematic random sample consisting of 10 per cent of the population, where 572 usable questionnaires were returned. Reliabilities of scales were assessed via Cronbach’s alpha, and hypotheses were tested via t-test, analysis of variance and hierarchical regressions.

Findings
The results showed that after controlling for other studied variables, students’ perceived quality of university administrative services explains 5.6 and 4.1 per cent of their behavioral intentions to transfer to a different university and to recommend their university, respectively. Further, when considering individually the five dimensions of students’ perceived quality of university administrative services, they explain 7.1 and 16.4 per cent of students’ behavioral intentions to transfer to a different university and to recommend their university, respectively. Furthermore, students’ gender moderates the influence of assurance on students’ intentions to recommend, as this moderating effect explains 2.7 per cent of students’ intentions to recommend.

Originality/value
This study addresses for the first time the influences for the perceived quality of the administrative services provided by a Jordanian public university on the behavior intentions after controlling for several variables including intention to leave university study and finding a moderating role for students’ gender.

PurposeThe purpose of this paper is to create a universal (asset-class-independent) portfolio risk index for a global private investor.Design/methodology/approachThe authors first discuss existing risk measures and desirable properties of a risk index. Then, they construct a universal (asset-class-independent) portfolio risk measure by modifying Financial Turbulence of Kritzman and Li (2010). Finally, the average portfolio of a representative global private investor is determined, and, by applying the new portfolio risk measure, they derive thePrivate investorRiskIndeX.FindingsThe authors show that this index exhibits commonly expected properties of risk indices, such as proper reaction to well-known historical market events, persistence in time and forecasting power for both risk and returns to risk.Practical implicationsA dynamic asset allocation example illustrates one potential practical application for global private investors.Originality/valueAs of now, a risk index reflecting the overall risk of a typical multi-asset-class portfolio of global private investors does not seem to exist.
Wear analysis on EN8, EN9 and EN24
Authors: R. Suraj , K.S. Jithish 
Published: March 2017

Purpose
This paper aims to present a comparative study of the wear properties of ferrous welded materials like EN8, EN9 and mild steel (MS).

Design/methodology/approach
The material is cut into specific dimension after hardfacing and is studied for the wear properties of the material. The wear testing is done on a pin-on-disc apparatus. The microhardness of the material is studied using the Vickers microhardness measuring apparatus.

Findings
The wear properties of ferrous welded materials like EN8, EN9 and MS are studied. It is found the MS has the least wear when compared to EN8 and EN9. The microhardness of MS is higher than EN8 and EN9, thus making it more wear-resistant than EN8 and EN9. The coefficient of friction in the dry sliding condition is found to be constant throughout the experiment.

Research limitations/implications
Major restriction is the amount of time required for use-wear analysis and replication experiments that are necessary to produce reliable results. These limitations mean that the analysis of total assemblages with the intention of producing specific results, especially of worked materials, is not feasible.

Practical implications
Generally, the complexity and rigour of the analysis depend primarily on the engineering needs and secondarily on the wear situation. It has been the author’s experience that simple and basic wear analyses, conducted in the proper manner, are often adequate in many engineering situations. Integral and fundamental to the wear analysis approach is the treatment of wear and wear behaviour as a system property. As a consequence, wear analysis is not limited to the evaluation of the effects of materials on wear behaviour. Wear analysis often enables the identification of nonmaterial solutions or nonmaterial elements in a solution to wear problems. For example, changes in or recommendations for contact geometry, roughness, tolerance and so on are often the results of a wear analysis.

Originality/value
The value of the work lies in the utility of the results obtained to researchers and users of the EN8, EN9 and EN24 material for their components.

Authors: Pourjavaheri Firoozeh , Mohades Farzad , Jones Oliver , Sherkat Frank , Kong Ing , Gupta Arun , Shanks Robert A. 
Published: March 2017

Purpose
This paper aims to use the solvent–casting–evaporation method to prepare new bio-composites with thermoplastic poly(ether urethane) (TPU-polyether) as the polymer matrix and reinforced with natural chicken feather fibre (CFF).

Design/methodology/approach
To produce the bio-composites, 0 to 60 per cent·w/w of fibres in steps of 30 per cent·w/w were added to the polymer matrix. The uniformity of distribution of the keratin fibres in the polymer matrix was investigated via scanning electron microscopy, and the results suggested compatibility of the TPU-polyether matrix with the CFFs, thereby implying effective fibre–polymer interactions.

Findings
Addition of natural fibres to the polymer was found to decrease the mass loss of the composites at higher temperatures and decrease the glass transition temperature, as well as the storage and loss modulus, at lower temperatures, while increasing the remaining char ratio, storage modulus and loss modulus at higher temperatures.

Originality/value
The investigation confirmed that waste keratin CFF can improve the thermo-mechanical properties of composites, simply and cheaply, with potentially large environmental and economic benefits.
The design of visco‐acoustic weighted L1‐error frequency–space wavefield extrapolators
Authors: Abdul Salam Syed , Mousa Wail A. 
Published: March 2017

ABSTRACTSeismic imaging is an important step for imaging the subsurface structures of the Earth. One of the attractive domains for seismic imaging is explicit frequency–space (f – x) prestack depth migration. So far, this domain focused on migrating seismic data in acoustic media, but very little work assumed visco‐acoustic media. In reality, seismic exploration data amplitudes suffer from attenuation. To tackle the problem of attenuation, new operators are required, which compensates for it. We propose the weighted L1‐error minimisation technique to design visco‐acoustic f – x wavefield extrapolators. The L1‐error wavenumber responses provide superior extrapolator designs as compared with the previously designed equiripple L4‐norm and L∞‐norm extrapolation wavenumber responses. To verify the new compensating designs, prestack depth migration is performed on the challenging Marmousi model dataset. A reference migrated section is obtained using non‐compensating f – x extrapolators on an acoustic dataset. Then, both compensating and non‐compensating extrapolators are applied to a visco‐acoustic dataset, and both migrated sections are then compared. The final images show that the proposed weighted L1‐error method enhances the resolution and results in practically stable images.
Practical and robust experimental determination of c13 and Thomsen parameter δ
Authors: Yan Fuyong , Han De‐Hua , Chen Xue‐Lian 
Published: March 2017

ABSTRACTWe analysed the complications in laboratory velocity anisotropy measurement on shales. There exist significant uncertainties in the laboratory determination of c13 and Thomsen parameter δ. These uncertainties are primarily related to the velocity measurement in the oblique direction. For reliable estimation of c13 and δ, it is important that genuine phase velocity or group velocity be measured with minimum uncertainty. The uncertainties can be greatly reduced if redundant oblique velocities are measured. For industrial applications, it is impractical to make multiple oblique velocity measurements on multiple core plugs. We demonstrated that it is applicable to make multiple genuine oblique group velocity measurements on a single horizontal core plug. The measurement results show that shales can be classified as a typical transversely isotropic medium. There is a coupling relation between c44 and c13 in determining the directional dependence of the seismic velocities. The quasi‐P‐wave or quasi‐S‐wave velocities can be approximated by three elastic parameters.
Inadvertent P‐hacking among trials and systematic reviews of the effect of progestogens in pregnancy? A systematic review and meta‐analysis
Authors: Prior M , Hibberd R , Asemota N , Thornton JG 
Published: March 2017

BackgroundProgestogens have been evaluated in numerous trials and meta‐analyses, many of which concluded they were effective. However, two large trials PROMISE and OPPTIMUM have recently concluded that progesterone was ineffective. This raises the possibility that earlier studies and reviews had been biased by either selective publication or selective choice of outcomes, so called “P‐hacking”.ObjectivesTo compare the findings all progestogen trials and systematic reviews with those of trials with pre‐registered primary outcomes which avoided selective outcome reporting.Search strategySearch of PubMed, the Cochrane Library and trial registries. Registration PROSPERO CRD42016035303.Selection criteriaSystematic reviews of randomised trials comparing progestogen with placebo in pregnancy and the individual trials included in those reviews. The subset of trials reporting a pre‐registered primary outcome were compared with the totality of trials and reviews.Data collection and analysisFor reviews all outcomes were included. For individual trials all outcomes reported in the systematic reviews were included. For the comparison group we recorded the registered primary outcome from trials that were either registered before they started, or registered during the recruitment phase and also double blind.Main resultsNineteen of twenty‐nine meta‐analyses concluded that progestogens were effective. Twenty‐two trials reported their pre‐registered primary outcomes. There was no effect of progesterone on primary registered dichotomous outcome RR 1.00 (95% CI 0.94–1.07). Only one of the 22 showed a nominally statistically significant benefit.Author's conclusionsWhen evaluated in registered double‐blind trials with analysis restricted to predefined primary outcomes, progestational agents in pregnancy are ineffective.Tweetable abstractProgestogens to prevent pregnancy loss, an example of P‐hacking.
Does antenatal care timing influence stillbirth risk in the third trimester? A secondary analysis of perinatal death audit data in South Africa
Authors: Lavin T , Pattinson RC 
Published: March 2017

ObjectiveTo explore stillbirth risk across gestation in three provinces of South Africa with different antenatal care schedules.DesignRetrospective audit of perinatal death data using South Africa's Perinatal Problem Identification Programme.SettingIn 2008, the Basic Antenatal Care Programme was introduced in Limpopo and Mpumalanga provinces, reducing appointments to five visits at booking, 20, 26, 32, 38 weeks and 41 weeks if required. In the Western Cape province seven appointments remained at booking, 20, 26, 32, 34, 36, 38 and 41 weeks if required.PopulationAll audited stillbirths (n = 4211) between October 2013 to August 2015 in Limpopo, Mpumalanga and Western Cape.MethodsStillbirth risk (26–42 weeks of gestation, >1000 g) across gestation was calculated using Yudkin's method. Stillbirth risk was compared between provinces and relative risks were calculated between Limpopo/ Mpumalanga and Western Cape.Main outcome measuresStillbirth risk across gestation.ResultsStillbirth risk peaked at 38 weeks of gestation in Limpopo (relative risk [RR] 3.11, 95% CI 2.40–4.03, P < 0.001)and Mpumalanga (RR 3.09, 95% CI 2.37–4.02, P < 0.001) compared with Western Cape, where no peak was observed. Stillbirth risk at 38 weeks gestation in Limpopo and Mpumalanga were statistically greater than both the 37 and 39 weeks gestation within provinces (P < 0.001). As expected, a peak at 41 weeks of gestation was observed in all provinces.ConclusionsThe increased period of stillbirth risk occurs after a 6‐week absence of antenatal care. This calls for a refocus on the impact of reduced antenatal care visits during the third trimester.Tweetable abstractReduced antenatal care in the third trimester may increase stillbirth risk.
A research agenda for moving early medical pregnancy termination over the counter
Authors: Kapp N , Grossman D , Jackson E , Castleman L , Brahmi D 
Published: March 2017

Given the overall safety profile and increasing availability of medical pregnancy termination drugs, we asked: would the mifepristone–misoprostol regimen for medical termination at ≤10 weeks of gestation meet US Food and Drug Administration regulatory criteria for over‐the‐counter (OTC) approval, and if not, what are the present research gaps? We conducted a literature review of consumer behaviours necessary for a successful OTC application for medical termination at ≤10 weeks of gestation and identified crucial research gaps. If we were to embark on a development programme for OTC or more generally, self‐use of medical termination, the critical elements missing are the label comprehension, self‐selection and actual use studies.Tweetable abstractConsidering medical pregnancy termination through the over‐the‐counter regulatory lens clarifies critical evidence gaps.

Published: March 2017

AbstractObjectivesThe aim of this study was to review mental health patients transported by a dedicated statewide critical care retrieval team before and after the implementation of a ketamine sedation guideline.MethodsThis is a a retrospective cohort study of mental health patients with acute behavioural disturbance, transported between January 2010 and December 2015.ResultsA total of 78 patients were transported in the study period, 50 before and 28 after implementation of the ketamine guideline in June 2013. The introduction of the ketamine guideline was associated with a significant reduction in intubation for transport (36.00 vs 7.14%) (odds ratio 0.14, 95% confidence interval 0.02–0.71, P < 0.01). The likelihood of utilising ketamine for non‐intubated patients (n = 58) was higher in the period after implementation (37.50 vs 84.62%, odds ratio 9.17, 95% confidence interval 2.54–33.08, P < 0.005). The incidence of complications in our series was low.ConclusionsThe implementation of a ketamine clinical practice guideline for agitated mental health patients was associated with an increase in the number of patients receiving ketamine as part of their sedation regime and a reduction in the number of patients requiring intubation for transport. Appropriately trained critical care retrieval teams should consider ketamine as part of the sedation regime for agitated mental health patients.
