Authors: Van Sang Quang , Le-Hoai Long , Dang Chau Ngoc 
Published: April 2019

PurposeThe purpose of this paper is to predict implementation cost contingencies for residential construction projects in flood-prone areas, where floods with storms frequently cause serious damage and problems for people.Design/methodology/approachExpert interviews are conducted to identify the study variables. Based on bills of quantities and project documents, historical data on residential construction projects in flood-prone areas are collected. Pearson correlation analysis is first used to check the correlations among the study variables. To overcome multicollinearity, principal component analysis is used. Then, stepwise multiple regression analysis is used to develop the cost prediction model. Finally, non-parametric bootstrap method is used to develop range estimation of the implementation cost.FindingsA list of project-related variables, which could significantly affect implementation costs of residential construction projects in flood-prone areas, is identified. A model, which is developed based on an integration of principle component analysis and regression analysis, is robust. Regarding range estimation, 10, 50 and 90 percent cost estimates, which could provide information about the uncertainty levels in the estimates, are established. Furthermore, implementation cost contingencies which could show information about the variability in the estimates are determined for example case projects. Such information could be critical to cost-related management of residential construction projects in flood-prone areas.Originality/valueThis study attempts to predict implementation cost contingencies for residential construction projects in flood-prone areas using non-parametric bootstrap method. Such contingencies could be useful for project cost budgeting and/or effective cost management.

Authors: Anasi Stella Ngozi , Lawal Folasade Olufunke , Paul-Ozieh Abiola 
Published: April 2019

Purpose
Community pharmacists need good retrieval skills and competencies for effective use of online information resources for professional practice. This study aims to ascertain the internet literacy skills of community pharmacists in Lagos State, Nigeria.

Design/methodology/approach
A survey research design was adopted for the study. Convenience sampling technique was used in selecting community pharmacists. Questionnaire was the instrument used for data collection, whereas descriptive and inferential statistics were used for data analysis.

Findings
The study revealed that community pharmacists possess requisite internet literacy skills for effective use of online health information resources. There is a positive relationship between informational and operational internet literacy skills [r = 0.820, p(0.000) < 0.05], informational and strategic internet literacy skills [r = 0.838, p(0.000) < 0.05] and operational and strategic internet literacy skills [r = 0.810, p(0.000) < 0.05]. There is a statistically significant gender difference in the level of skillfulness in internet use based on self-reported skills. There is a significant relative contribution of demographic variables (gender, age, educational qualification and number of years in professional practice) to the level of skillfulness in internet use among community pharmacists.

Practical implications
To improve the use of online internet resources, the Association of Community Pharmacists of Nigeria, Lagos Chapter, should conduct training needs assessment regularly to offer the right levels of internet use skills. They must be proactive and incorporate training on computer and internet skills into their annual conferences and zonal meetings. They should also prepare and give internet use manuals to their members to read and understand how to use the internet more effectively. Community pharmacists, especially the female pharmacists, should also take advantage of free online training sessions called webinars to improve their internet literacy skills to cope with rapid changes in the e-environment, as well as to boost the quality of health-care services delivery. Pharmacists’ Council of Nigeria, the agency responsible for regulating and controlling the education, training and practice of pharmacy, should include an internet literacy skills module in the Mandatory Professional Continuing Education Programme.

Originality/value
The study investigated the internet literacy skills of community pharmacists in Lagos State and identified the gender gap in level of skillfulness. This study also explored the relationship between level of skillfulness and internet use, as well as the relationship between community pharmacists’ informational, operational and strategic internet literacy skills.
Applicability of solitary model of information behavior in students’ collaborative learning assignments
Authors: Ndumbaro Faraja , Mutula Stephen 
Published: April 2019

PurposeThis paper aims to present results of a study which examined students’ collaborative information behavior (CIB) in comparison with behavioral patterns illustrated in Wilson’s (1996) model of information behavior.Design/methodology/approachA total of six groups of undergraduate students; four from Sokoine University of Agriculture (SUA) and two from Ardhi University (ARU) were purposively selected. Data were collected using semi participant observation, critical incident interviews and focus group discussion methods.FindingsResults indicate that students’ CIB is mainly shaped by collaborative learning environment, learning tasks objectives and requirements. Despite its wider applicability in different domains and contexts, Wilson’s (1996) model is partially appropriate in modeling students’ group-based learning information behavioral activities. Person(s) in context and active and passive information seeking are aspects of the model which are observed to be relevant in students’ CIB.Practical implicationsThe study has implications on teaching and learning practices in higher learning institutions.Originality/valueThe study provides new insights on how students exhibit different information behavioral patterns during collaborative learning. The study fills a gap on how solitary models of information behavior can be used to model students’ information behavior in team-based learning.

Authors: Gummerus Johanna , Lipkin Michaela , Dube Apramey , Heinonen Kristina 
Published: April 2019

PurposeThis study aims to introduce and characterize a specific form of self-service technology (SST), customer self-service devices (SSDs), as well as propose and apply a classification scheme of SSDs to encourage future research on such SSTs.Design/methodology/approachThe paper is based on conceptual development of customer SSDs and exploratory qualitative insight from representatives of companies offering various types of SSDs.FindingsThis paper introduces SSDs as customer-possessed and controlled smart service devices aiming to solve problems from the customer’s perspective, often within completely new, customer-defined service processes and ecosystems. SSDs are not confined to the company-controlled service environment, and customers may thus use them wherever and whenever they so wish. The study characterizes SSDs based on service and customer use features, as well as on the subject of the service act (self/other vs belongings) and nature of service act (monitoring vs acting).Research limitations/implicationsThis study is limited to conceptual exploration with qualitative insights from six companies. Future research is needed to empirically study different SSDs by using both qualitative and quantitative approaches in various settings.Originality/valueThe paper conceptualizes SSDs as an extension to the traditional SST framework. It contributes to the understanding of how personal handheld devices can contribute to customer experiences. It provides research directions to stimulate further research in SSTs.
A five-year retrospective on an undergraduate SMIF program
Authors: Mullen Michael G. , Salvucci Debra 
Published: April 2019

Purpose
For undergraduate-only, AACSB-accredited business programs, establishing a student managed investment fund (SMIF) can be an enormous, but potentially worthwhile, undertaking. Resources are often very limited – especially for faculty where their time is already consumed by teaching, administrative and publishing requirements. The purpose of this paper is to reflect on the five-year experience at Stonehill College and suggest considerations for undergraduate institutions seeking to establish such programs.

Design/methodology/approach
This is a retrospective on the experience of designing and implementing a SMIF-based academic program. Student education and professional skill development should be the primary outcomes evaluated with such programs. Included are brief perspectives on the program from its alumni with commentary on perceived value in one to four years following graduation.

Findings
The experience to date suggests that establishing a SMIF at a smaller, undergraduate-only institution is challenging. For a SMIF to generate educational returns commensurate with its cost, it needs to be part of a comprehensive, academic-driven program that garners broad support by the business faculty and administration of the college. Personal reflections by its program alumni suggest that it can be a very meaningful academic and experiential learning opportunity.

Research limitations/implications
This paper is focused largely on the experience of one institution. Further insights may be attained by a broader, unbiased analysis of institutions where SMIF programs have succeeded or failed to meet similar objectives.

Practical implications
The authors suggests that the creation of a SMIF program at smaller, undergraduate-only institutions faces unique challenges relative to larger, more well-endowed universities. These challenges can be overcome but not without a broad internal commitment. These programs, if done in a comprehensive way, can significantly impact student outcomes.

Originality/value
The retrospective offers up-to-date insights on the value and challenges of starting a SMIF program at smaller-sized, undergraduate-only academic institutions.
Combined inversion of first‐arrival travel times and reflection travel times
Authors: Zhao Chongjin , Zhang Luolei , Yu Peng , Liu Yuzhu , Feng Shaokong 
Published: April 2019

ABSTRACTIn this work, we propose a method for determining reflection travel times based on the acquisition of first‐arrival travel times via the fast sweeping method. The accuracy of this scheme was proven by conducting model experiments to establish a foundation for first‐arrival tomography, reflection tomography and combined tomography. Reflection tomography was subsequently achieved using the adjoint‐state method; on this basis, we propose a combined tomography method involving both first‐arrival and reflection tomography. In the model experiments, excellent results were obtained via first‐arrival tomography, reflection tomography and our combined tomography method. Finally, full‐waveform inversion was performed, with the inversion produced by combined tomography used as the initial model. Excellent results were obtained using this approach. However, combined tomography reproduced and characterized the model much more realistically.

Authors: Morgan Kate , de Jersey Susan , Mason Belinda , Young Adrienne 
Published: April 2019

AimThis study aimed to determine satisfaction with dietetic services, identify barriers and enablers to engaging with dietetic services and acceptable methods of delivering nutrition care to patients on haemodialysis.MethodsA questionnaire was developed based on existing satisfaction surveys and key constructs from the Theoretical Domains Framework to understand patient behaviours around accessing dietetic services. Constructs were grouped according to the COM‐B model (Capability, Opportunity and Motivation) of the Behaviour Change Wheel to inform future interventions. Patients at three Brisbane haemodialysis units participated, with questionnaire administered via laptop (by dietetic assistants) or paper‐based version (by nurses).ResultsSixty‐six patients completed the questionnaire (response rate 40%, 62 ± 14 years, 58% male). Most respondents (n = 63, 95%) reported seeing a dietitian since commencing haemodialysis. A quarter of respondents reported declining or not wanting to see the dietitian. Despite this, questions pertaining to service satisfaction were largely positive. Questions related to enablers and barriers to engaging with the dietitian revealed the domain of motivation as the main barrier with 41% (n = 26) participants not wanting to make dietary changes. The domains of capability and opportunity were not barriers. Patients preferred receiving nutrition information from dietitians, when they had a question or concern, rather than at predefined intervals. Telehealth was not acceptable to the majority of participants.ConclusionsWhile patients were satisfied with dietetic care, their preferences for dietetic service delivery were not aligned with current evidence‐based guidelines, highlighting need for alternative models of care. Dietetic interventions need to be delivered in a way that addresses motivation.
Characterization of Emulsion Stabilization Properties of Gum Tragacanth, Xanthan Gum and Sucrose Monopalmitate: A Comparative Study
Authors: Pocan Pelin , Ilhan Esmanur , Oztop Mecit Halil 
Published: April 2019

AbstractEmulsification effect of gum tragacanth (GT) obtained from Astragalus species is gaining particular interest in recent years. In this study, stabilization effect of GT, xanthan gum (XG), and sucrose monopalmitate (SMP) was investigated by keeping their concentration constant (0.5% w/v) for the oil‐in‐water emulsions containing 20% (v/v) sun flower oil and 2% (w/v) whey protein isolate. Emulsification was achieved by using high shear homogenization. Particle size and T2 (spin–spin relaxation time) measurements were performed for the characterization and repeated over the course of 28 days. Emulsion stability index (ESI [%]) was measured and rheological characterization was also performed. The lowest particle size was found for the XG emulsions and this was attributed to the pseudoplastic behavior of xanthan compared to GT (nXanthan = 0.188 ≪ nGT = 0.721). Xanthan emulsions thinned out dramatically when sheared during homogenization, and consequently, floccules formed could have been disrupted more resulting in smaller particle size. Result of rheological experiments showed that SMP emulsions were fit to Newtonian model, while XG and GT showed shear thinning behavior and fit to a power law model. Apparent viscosity of XG emulsions was found significantly higher than the GT ones. The most stable emulsions were the ones prepared by XG and they remained stable during 28 days. Although GT emulsions could not protect their stability during 28 days, ESI (%) results were found similar with XG indicating promising emulsification effect of GT.Practical ApplicationGum tragacanth, xanthan gum, and sucrose monopalmitate have been used to formulate oil‐in‐water emulsions. The final formulated products can be used in emulsion‐based food products to increase their stability and shelf life.
Cannabis‐dependent adolescents show differences in global reward‐associated network topology: A functional connectomics approach
Authors: Nestor Liam J. , Behan Brendan , Suckling John , Garavan Hugh 
Published: April 2019

AbstractAdolescence may be a period of increased vulnerability to the onset of drug misuse and addiction due to changes in developing brain networks that support cognitive and reward processing. Cannabis is a widely misused illicit drug in adolescence which can lead to dependence and alterations in reward‐related neural functioning. Concerns exist that cannabis‐related alterations in these reward networks in adolescence may sensitize behaviour towards all forms of reward that increase the risk of further drug use. Taking a functional connectomics approach, we compared an acutely abstinent adolescent cannabis‐dependent (CAN) group with adolescent controls (CON) on global measures of network topology associated with anticipation on a monetary incentive delay task. In the presence of overall superior accuracy, the CAN group exhibited superior global connectivity (clustering coefficient, efficiency, characteristic path length) during monetary gain anticipation compared with the CON group. Additional analyses showed that the CAN group exhibited significantly greater connectivity strength during monetary gain anticipation across a subnetwork that included mesocorticolimbic nodes involving both interhemispheric and intrahemispheric connections. We discuss how these differences in reward‐associated connectivity may allude to subtle functional alterations in network architecture in adolescent cannabis‐dependence that could enhance the motivation for nondrug reward during acute abstinence.

Published: April 2019

SummaryGender assignment errors are common in some animal species and lead to inaccuracies in downstream analyses. Procedures for detecting gender misassignment are available for array‐based SNP data but are still being developed for genotyping‐by‐sequencing (GBS) data. In this study, we describe a method for using GBS data to predict gender using X and Y chromosomal SNPs. From a set of 1286 X chromosomal and 23 Y chromosomal deer (Cervus sp.) SNPs discovered from GBS sequence reads, a prediction model was built using a training dataset of 422 Red deer and validated using a test dataset of 868 Red deer and Wapiti deer. Prediction was based on the proportion of heterozygous genotypes on the X chromosome and the proportion of non‐missing genotypes on the Y chromosome observed in each individual. The concordance between recorded gender and predicted gender was 98.6% in the training dataset and 99.3% in the test dataset. The model identified five individuals across both datasets with incorrect recorded gender and was unable to predict gender for another five individuals. Overall, our method predicted gender with a high degree of accuracy and could be used for quality control in gender assignment datasets or for assigning gender when unrecorded, provided a suitable reference genome is available.
