Breaking the flow: a study of contradictions in information systems development (ISD)
Authors: Dennehy Denis , Conboy Kieran 
Published: August 2019

Purpose
The purpose of this paper is to examine contradictions (specifically tertiary and quaternary contradictions) that can disrupt the flow of work in contemporary systems development methods.

Design/methodology/approach
This study uses Activity theory (AT) as a theoretical lens to: examine ISD flow as an interrelated activity system; and identify contradictions. AT is pertinent in the context of this study as rather than view contradictions as a threat to prematurely abandon the use of flow tools and metrics, it shows how contradictions can act as a motor for change and continuity. This study adopts a longitudinal single case study approach including face-to-face interviews with management and software development project teams, as well as direct observations and document analysis.

Findings
This study identifies tertiary and quaternary contradictions, and highlights the influence of contradictions on flow-based systems development.

Social implications
This study provides a set of contradictions for researchers and practitioners. It shows that contradictions can be culturally or politically challenging to confront, and even when resolved, can have intended or unintended consequences.

Originality/value
This paper fulfils an identified need to study ISD flow from the perspective of interrelated activity systems and beyond its initial implementation phase.

Published: August 2019

PurposeThis paper aims to evaluate the protective potential of prickly pear cactus fresh cladodes (opuntia ficus indica (OFI)) on glycemic disorders, dyslipidemia, prooxidant/antioxidant stress biomarkers and reverse cholesterol transport (by evaluating the activity of lecithin-cholesterol acyltransferase (LCAT)) and paraoxonase (PON1) in rats prematurely exposed to cafeteria diet (CD).Design/methodology/approachSixteen young rats were divided into two groups fed CD containing 50 per cent of hyperlipidic diet (HLD) and 50 per cent of junk food mix supplemented or not with 50 g of fresh young cladodes of OFI to 100 g of CD, during 30 days.FindingsOFI cladodes supplementation decreased significantly body weight (p < 0.001), food intake (p < 0.05), adipose tissue weight (p < 0.01), fasting glycemia and glycosylated hemoglobin (p < 0.01), homeostasis model assessment (HOMA-IR) and insulinemia (p < 0.001), levels of cholesterol (C) (p < 0.05) and triacylglycerols (TG) (p < 0.01) in serum and in very low-density lipoproteins (VLDL-Cp < 0.05 and VLDL-TGp < 0.01) and improves reverse cholesterol transport by increasing high-density lipoprotein cholesteryl-esters concentrations (p < 0.001) and by stimulating LCAT activity. Moreover, they attenuated lipid peroxidation in VLDL and low-density lipoproteins by increasing atheroprotective activity of PON-1 and in liver and adipose tissue by enhancing enzymatic antioxidant defence.Social implicationsThe young cladodes of OFI because of their antiobesity benefits could constitute a novel functional ingredient in pharmaceutical and nutraceutical applications.Originality/valueYoung cladodes of OFI in rat precociously submitted to a hyperlipidic diet/junk food (cafeteria model) seem to prevent metabolic disorders associated with obesity.
Legal framework challenges to e-banking in Tanzania
Authors: Kato Charles Ishengoma 
Published: August 2019

Purpose
This paper aims to examine the legal challenges to electronic banking and initiatives taken to address them in Tanzania. It is based on the results of a comparative analysis of policies and laws of other countries from which Tanzania can pick a leaf on how to deal with challenges brought by information and communication technology-induced innovations in the banking sector.

Design/methodology/approach
The study upon which this paper is based employed comparative analysis methods by analysing different policies and laws of Tanzania in line with attendant laws of other jurisdictions such as the USA, Malaysia, South Africa, Rwanda and Kenya and international instruments in a bid to establish the best practice pertaining to controlling and containing legal challenges brought by developments in electronic banking.

Findings
This paper confirms that, the prevailing laws guiding electronic banking in Tanzania do not adequately address the challenges the banks and customers face during electronic banking transactions. Thus, there is a need to amend the Tanzanian laws guiding this sector to put in place legislation capable of facilitating the development of electronic banking whilst addressing the associated challenges the users encounter.

Originality/value
This paper underscores the value of amending existing or enacting new laws in line with the development of technology/innovation to protect consumers in nascent electronic banking of the country. Moreover, it advocates for the development of innovation in banking sector should not be left to grow without amending/enacting laws that will promote its development and at the same time protect the users to avoid far-reaching and often unpleasant implications.
Does ownership concentration affect cost of debt? Evidence from an emerging market
Authors: Jabbouri Imad , Naili Maryem 
Published: August 2019

PurposeThe purpose of this paper is to explore how ownership concentration affects cost of debt (CoD) in one of the most important emerging markets in the Middle East and North Africa, Morocco.Design/methodology/approachThe study employs panel data analysis using non-financial firms listed on Casablanca Stock Exchange (CSE) between 2004 and 2016. To unveil the hidden facets of the relationship between ownership concentration and CoD, and examine if this relationship changes with market conditions, we conduct a pre–post-crisis analysis.FindingsThe results demonstrate that controlling shareholders promote decent governance as long as they are able to generate appropriate returns. However, this behavior seems to change during the post-crisis period. In their attempts to increase their returns adversely affected by the financial crisis, controlling shareholders switch from guardians of decent governance and firm’s resources to a menace to creditors’ interests.Practical implicationsOur results expose the severity of agency problems in CSE. It is the duty of all market participants including regulators, board of directors, financial analysts, shareholders and creditors to scrutiny and reinforce governance mechanisms to alleviate expropriation by controlling shareholders. Improving country and firm-level governance mechanisms would enhance investors’ protection, attract international investors and boost the economic activity.Originality/valuePrior research is inconclusive about the impact of ownership concentration on CoD. Hence, it is worthwhile to seek new evidence in a new market on the nature of this relationship.
Why Indian cities are so chaotic? Decoding from the urban development efforts of Chandigarh
Authors: Biswas Arindam 
Published: August 2019

PurposeThe purpose of this paper is to compare and learn from Chandigarh in addressing an orderly urbanisation in India. Chandigarh is considered as a benchmark for city design in India. The aim is recapitulate the city design process and garner useful inputs towards city design process in India.Design/methodology/approachConsidering the purpose of the study, two research methodologies are identified – namely “case study” and “analytical narrative”. A case study method is usually focused on certain urban systems with a view to explain why certain systems were a success and why some ended up being a failure. It mostly concerns itself with questions of efficiency. A narrative analysis seeks to understand urban development process and change. It appeared in disciplines such as policy analysis, urban history, social science, political science and economics. Analytical narrative evaluates the explanatory performance of new genre, using some philosophy.FindingsThis paper contributes in reinvigorating the aura of Chandigarh and its contribution in developing an Indian city with its own identity. It also reflects upon the series of failure among the recent city planning endeavours, and its avenue of differences from the successful case.Originality/valueThe paper contributes in understanding the existing shortcomings of city design approaches in India from the perspective of a relatively successful case of a functional Indian city. It also helps to point out the forgotten dimensions of city design that contributes in creating a functional city.

The Pacific Emergency Medicine Mentoring Program: A model for medical mentoring in the Pacific region
Authors: Phillips Georgina , Lee Dennis , Shailin Shivani , O'Reilly Gerard , Cameron Peter 
Published: August 2019

AbstractObjectiveTo describe the development and implementation of a Pacific medical mentoring programme and to evaluate the programme after the first year.MethodsThe mentoring programme was adapted from Australasian College for Emergency Medicine resources and involved Australian emergency physicians mentoring Pacific Island Country doctors. Using a prospective, cross‐sectional survey of all participants, researchers collected data that were analysed for content using deductive and inductive methods. Content analysis aimed to generate new concepts that could apply to different components of mentoring, and overarching themes that apply to the mentoring programme overall.ResultsNineteen doctors participated in the first year of the programme; 11 mentees from three different Pacific Island Countries and eight Australasian College for Emergency Medicine Fellow mentors. The survey was completed with a 100% response rate. Five core themes were identified from the data: vital face‐to‐face communication (the key to effective communication); supportive personal relationship (valued and desired by mentees); motivating professional relationship (including a regional Pacific network); substantial challenges (time, distance, remote communication); and issues around the mentoring model (goal‐orientation, mentor‐driven, culture).ConclusionsThe present study suggests a new model of Pacific mentoring that recognises the centrality of the mentoring relationship, and allows for flexible communication, shared responsibility of mentors and mentees as co‐drivers and a broad understanding of goals and timelines. Future programmes should incorporate funding for in‐person meetings and educational opportunities to enhance contextual and cultural understanding. These lessons can inform future medical mentorship programmes across the Pacific.
Computer‐mediated communication and social support among community‐dwelling older adults: A systematic review of cross‐sectional data
Authors: Fuss Belinda G. , Dorstyn Diana , Ward Lynn 
Published: August 2019

AbstractObjectiveTo systematically assess the relationship between computer‐mediated communication and social function in older adults aged 55 or older.MethodsEmbase, PsycINFO and PubMed were searched (database inception to December 2018). Where available, effect sizes (correlation r) with 95% confidence intervals and P values were calculated for individual studies. Of 4,139 eligible articles retrieved, 17 studies involving a pooled sample of 17,640 participants were included.ResultsFrequent computer‐mediated communication was significantly, albeit weakly, associated with higher levels of social support and connectedness (r range = 0.08 to 0.33, P < 0.05). One discrepant negative relationship was noted (r = −0.16, 95% CI [−0.30, −0.02], P = 0.03), involving a distinct sample of gamers.ConclusionsComputer‐mediated communication is related to amount of social functioning in older adults, although the causal nature of this relationship requires further longitudinal investigation. Sample confounds (eg socio‐economic status and successful ageing) may limit the interpretation of these findings.
Application of the slope‐ratio growth assay technique to estimate tryptophan availability in soybean meal fed to young rats
Authors: Sato Hiroyuki , Miura Makoto , Fujieda Takeshi , Toyomizu Masaaki 
Published: August 2019

AbstractThe slope‐ratio assay for rat was used to determine whether tryptophan (Trp) availability in soybean meal (SBM) is affected by the presence of other amino acids (AAs). In a preliminary study, rats were fed graded levels of Trp‐supplemented diets to establish the Trp concentration range over which the weight gain response was linear. This range was found to be from 0.04% to 0.12% Trp. Subsequently, rats were fed basal (0.045% Trp) or Trp‐supplemented diets from three different sources: l‐Trp alone, SBM, or l‐Trp mixed with other AAs to reflect AA levels in the test SBM (AA‐mix). Weight gain in rats increased linearly with supplemental Trp intake (p < .05) for all Trp sources. Compared to the slope achieved with l‐Trp alone, the estimated availability of Trp in SBM was 84.4%, while for the AA‐mix it was 93.4%. It is evident that the 6.6% reduction in l‐Trp availability in AA‐mix is due to metabolic costs derived from excess levels of other AAs beside Trp, given that the absorption of crystalline l‐Trp in the small intestine is 100%. In conclusion, the Trp availability of SBM was estimated to be around 90.4% (i.e., 84.4/93.4 × 100) after correcting for the effects of the other AAs in SBM.

AbstractSulfanilamide (SA) is an effective broad‐spectrum antibacterial agent in human and veterinary medicine. The purpose of this study was to evaluate the effects of SA on boar sperm quality during liquid storage at 17°C and determine the optimal concentration of SA and its effects on bacterial growth, microbial composition, and maternal fertility. Boar ejaculates were diluted with a basic extender, containing different concentrations of SA, and stored in a 17°C incubator for 6 days. The sperm motility, plasma membrane integrity, and acrosome integrity were measured daily. The results showed that when the concentration of SA was 0.02 g/L, the sperm quality parameters were significantly higher than those of all other treatment groups (p < .05). We also monitored the bacterial growth and compared the differences in the microbial species between the 0.02 g/L SA group and the control by 16S rDNA sequencing. The results revealed that some bacteria, such as Staphylococcus and Pseudomonas, were considerably lower in the 0.02 g/L SA group than in the control group (p < .05). In addition, preserved semen was used for artificial insemination, and results showed that 0.02 g/L SA group had a higher litter size, and its pregnancy rate was 92.5%.
Vancomycin is commonly under‐dosed in critically ill children and neonates
Authors: Sosnin Natasha , Curtis Nigel , Cranswick Noel , Chiletti Roberto , Gwee Amanda 
Published: August 2019

AimsVancomycin is frequently used in critically ill children in whom the drug pharmacokinetics are significantly altered as a result of changes in renal clearance and volume of distribution. Therapeutic drug monitoring (TDM) is recommended to achieve vancomycin trough concentrations between 10 and 20 mg/L. In this study we reviewed vancomycin dosing, TDM and treatment outcomes in paediatric and neonatal intensive care unit patients.MethodsWe reviewed the medical records of all patients receiving intravenous vancomycin in a tertiary paediatric and neonatal intensive care unit over a 10‐month period. Demographic, vancomycin dosing, TDM and drug‐related adverse effects data were collected.ResultsIn total, 115 children received 126 courses of vancomycin and had at least 1 TDM blood sample taken at steady state. In only 38/126 (30%) courses was the target concentration (10–20 mg/L) achieved at the initial steady state trough sample. Of the 88 courses that had initial trough concentrations outside the target range, the dose was adjusted in only 49 (56%). Overall, minimum doses of 30 mg/kg/day in neonates with a corrected gestational age of <35 weeks, and 50 mg/kg/day in older children, were required to achieve target vancomycin concentrations. Vancomycin‐attributable nephrotoxicity occurred in 10/126 (8%) courses and there were no episodes of red man syndrome.ConclusionIn critically ill children, individualised dosing is needed. In the absence of Bayesian model‐based dosing, in children with normal renal function, empiric vancomycin doses of at least 30 mg/kg/day in neonates of <35 weeks corrected gestational age, and 50 mg/kg/day in older children, should be considered. Optimisation of TDM practices through the development of protocols, ideally built into electronic medical records, should be considered.
The heart of educational data infrastructures = Conscious humanity and scientific responsibility, not infinite data and limitless experimentation
Authors: Johanes Petr , Thille Candace 
Published: August 2019

AbstractEducation and education research are experiencing increased digitization and datafication, partly thanks to the rise in popularity of massively open online courses (MOOCs). The infrastructures that collect, store and analyse the resulting big data have received critical scrutiny from sociological, epistemological, ethical and analytical perspectives. These critiques tend to highlight concerns and/or warnings about the lack of the infrastructures' and builders' understanding of various nontechnical aspects of big data research (eg seeing data as neutral rather than as products of social processes). These critiques have primarily come from outside of the builder community, rendering the conversation largely one‐sided and devoid of the voices of the builders themselves. The purpose of this paper is to re‐balance the conversation by reporting the results of interviews with 11 data infrastructure builders in higher education institutions. The interviews reveal that builders engage deeply with the issues the critiques outline, not only thinking about them, but also developing practices to address them. The paper focuses the findings on three themes: designing a productive science, navigating ubiquitous ethics and achieving real human impact. Researchers, policymakers and infrastructure builders can use these accounts to better understand the building process and experience.
Motivational profiles and their correlates among students in virtual school foreign language courses
Authors: Zhang Yining , Lin Chin‐Hsi 
Published: August 2019

AbstractMotivation is a key factor in predicting K‐12 students' online learning success. Drawing on self‐determination theory, this study used a person‐centered approach to identify the motivational profiles of students taking online high school language courses, and to examine such profiles' relationships to their learning outcomes, genders and reasons for enrollment. Cluster analysis of 466 students revealed the existence of four profiles: high and low quantity, and good and poor quality. Students in the high‐quantity profile demonstrated comparable learning outcomes to those in the good quality profile; and there was significant gender and enrollment reason differences across the four motivational profiles.
Practitioner NotesWhat is already known about this topic

Motivation is of considerable importance to the success of online learning.
Autonomous motivation is more adaptive than controlled motivation.
Most studies have used a variable‐centered approach to investigating the unique and independent roles of motivation types in online learning.
What this paper adds

This study is believed to be the first to use a person‐centered approach to identify motivational profiles (ie, good quality, high quantity, low quantity and poor quality) among virtual‐school students taking foreign‐language courses.
It confirms the positive effect of autonomous motivation on learning, and extends exploration of this effect to online learning.
Students in the high‐quantity profile achieved comparable learning outcomes to those in the good quality profile.
Females were overrepresented in the good quality profile (ie, more females than would be expected by chance).
Motivational profiles differed significantly across enrollment reasons (ie, credit recovery, elective or requirement).
Implications for practice and/or policy

Teachers should not simply place each student in a box as having either autonomous or controlled motivation.
Online learning content and activities should be designed in ways that promote autonomous motivation.
Online educators need to be aware of potential gender and enrollment reason effects on students' motivations.
