Published: January 2018

Purpose
The purpose of this paper is to explore the disparities in social awareness and use of the internet between urban and rural school children in the North of Vietnam.

Design/methodology/approach
A total of 525 pupils, aged 9-11 years old, randomly selected from seven urban and rural schools, who are internet users, participated in the study and consented to responding to a questionnaire adapted from an equivalent European Union study. A comparative statistical analysis of the responses was then carried out, using IBM SPSS v21, which consisted of a descriptive analysis, an identification of personal self-development opportunities, as well as issues related to pupils’ digital prowess and knowledge of internet use and internet safety, including parental engagement in their offspring’s online activities.

Findings
The study highlights the fact that children from both the urban and rural regions of the North of Vietnam mostly access the internet from home, but with more children in the urbanized areas accessing it at school than their rural counterparts. Although children from the rural areas scored lower on all the internet indicators, such as digital access and online personal experience and awareness, there was no disparity in awareness of internet risks between the two sub-samples. It is noteworthy that there was no statistically significant gender difference towards online activities that support self-development. In relation to safe internet usage, children are likely to seek advice from their parents, rather than through teachers or friends. However, they are not yet provided with an effective safety net while exposing themselves to the digital world.

Originality/value
Although the Vietnamese national curriculum on the computer science subject does not explicitly cover the use of the internet and its related aspects, the majority of children who took part in this study claimed to have used the internet in their learning activities. This emphasises the urgent need for the Ministry of Education and educators in the country to not only improve information and communication technology facilities in schools, but also to revise the computer science curriculum in order to provide a supportive environment for learning development and collectively advocate the dynamics of internet use in order to ensure safe access and use by the children.
Qualitative methods for engaging students in performance measurement
Authors: Appleton Leo 
Published: January 2018

Purpose
In the modern “student focused” university setting, quality assurance and continual service improvement have become more and more important in the delivery of academic library services. Working in partnership with their students, academic libraries can enable meaningful engagement, through qualitative methods which allow individual students to contribute to performance measurement activities and service development. The purpose of this paper is to discuss how qualitative methods can be used to engage students in the performance measurement activities of academic libraries.

Design/methodology/approach
Through a review of relevant literature, discussion around the main themes and some case study examples, this paper illustrates how effective student engagement through qualitative methods can contribute to the quality assurance, performance measurement and ultimate service improvement of academic libraries.

Findings
The paper focuses specifically on focus group and reflective methods and also details some elements of user experience (UX) which brings together different qualitative techniques available for academic libraries. The paper concludes with a feature case study which discusses how meaningful student engagement was achieved through a large-scale UX project at the University of the Arts, London.

Originality/value
The paper brings together many different discussions around qualitative methods in performance measurement and is original in its discussions around such activity as student engagement initiatives.
Planned conservation in Pompeii: complexity and methodological choices
Authors: Osanna Massimo , Rinaldi Enrico 
Published: January 2018

Purpose
The planned maintenance service, conducted within the scope of the Great Pompeii Project, presents a high degree of complexity. The purpose of this paper is to describe the methodological choices and operational practices which are being put into place, in order to allow a gradual transition from works of an extraordinary nature to a continuous and planned conservation initiative.

Design/methodology/approach
In line with changing perspectives on approaching maintenance, which have gained traction in Italy through research conducted over the last decade, the maintenance service of Pompeii has been proposed as a permanent “project site”, with the aim of presiding over the entire maintenance process (inspections, planning, checks in the execution phase, documentation and the organisation of feedback information).

Findings
Although the conservational benefits of the planned maintenance have become apparent with a long-term vision, the service has improved the accessibility and respectability of the ancient city in just a short time, enhancing the enjoyment of it, safety and the conservation of visitor routes. The domus and visitable building complexes are constantly monitored, and in many of them have already borne witness to short- and medium-term maintenance programs.

Originality/value
The service of maintenance which has been set up at Pompeii today constitutes an innovative experimental model, potentially replicable in other sites of archaeological heritage with wide room for improvement.
Establishing evaluation criteria for e-dictionaries
Authors: Ball Liezl H. , Bothma Theo J.D. 
Published: January 2018

Purpose
The purpose of this paper is to identify criteria according to which e-dictionaries can be evaluated. Information technology can be used to enhance e-dictionaries, but if not done carefully, information tools that completely overwhelm a user with irrelevant information can be developed. Criteria are necessary according to which e-dictionaries can be developed and evaluated to ensure tools that only provide relevant information on demand.

Design/methodology/approach
A literature review was conducted to identify trends in lexicography and modern information technology. Previous usability studies were considered to identify key usability issues. The information was synthesised to identify a set of criteria.

Findings
It was found the e-dictionaries should be evaluated according to their content, information architecture, navigation, access (searching and browsing), help, customisation and use of other innovative technologies.

Originality/value
A comprehensive set of criteria has been identified that can be used to evaluate e-dictionaries and to guide lexicographers in the development of e-dictionaries.
Caffeine: a boon or bane
Authors: Kumar Vikas , Kaur Jaspreet , Panghal Anil , Kaur Sawinder , Handa Vanshika 
Published: January 2018

Purpose
The purpose of this paper is to explore the sources of caffeine and its utilization in different food products, along with its impact on human health in terms of benefits and adverse effect.

Design/methodology/approach
The papers reviewed were selected based on the following key descriptors such as caffeine, sources, trends of consumption, utilization, benefits and adverse effects, regulation and labelling.

Findings
There are many physiological effects of caffeine on respiratory, cardiovascular, gastrointestinal, reproductive and central nervous system. It has a positive effect in reducing the risk of diabetes, Alzheimer’s disease, Parkinson’s disease and liver injury and, at the same time, in improving mood, psychomotor performance and immune response. On the other hand, the negative effects of caffeine include addiction, cancer, heart diseases, insomnia, gastrointestinal disturbances and intoxication. As caffeine, when taken in large amount, is harmful, therefore as per the regulatory bodies, its concentration should not exceed the set limit, and its presence needs to be listed on the label of that particular food product. In a nutshell, it can be said that caffeine acts as a boon as well as bane because it possesses both beneficial and adverse effects.

Originality/value
This is a unique and comprehensive review that will provide a brief overview of sources, utilization, healthful as well as harmful effect of caffeine to the readers.
Does internet search intensity predict house prices in emerging markets? A case of India
Authors: Venkataraman Madalasa , Panchapagesan Venkatesh , Jalan Ekta 
Published: January 2018

PurposeThe purpose of this paper is to examine whether internet search intensity, as captured by Google’s search volume index (SVI), predicts house price changes in an emerging market like India.Design/methodology/approachUsing data on Google’s SVI for four Indian cities and their corresponding house price index values, the authors examine whether abnormal SVI (growth in search intensity normalized by the national average) impacts abnormal house prices (house price change normalized by the national average).FindingsLike developed markets such as the USA, the authors find that internet search intensity strongly predicts future house price changes. A simple rebalancing strategy of buying a representative house in the city with the greatest change in search intensity and selling a representative house in the city with the smallest change in search intensity each quarter yields an annualized excess (over risk-free government T-bills) return of 4 percent.Originality/valueEmerging markets have low internet penetration and high information asymmetry with a dominant unorganized real estate market. The results are interesting as it sheds light on the nature and role of the internet as an infomediary even in emerging markets
No way to say “no”
Authors: Rao Jyoti , Tiwari Piyush , Hutchison Norman 
Published: January 2018

Purpose
Property often forms the biggest component of household wealth and assets. Irrespective of landowners’ willingness, the act of compulsory acquisition abruptly ceases the security that this ownership carries. This often induces dissatisfaction among affected landowners over the: loss of “property rights”; loss of commodity, or property; and loss of future opportunities associated with the property. Though there have been attempts in various land acquisition laws and a practice to compensate acquirees for their loss, the dissatisfaction of acquirees has persisted. The persisting resistance of landowners compels deeper insight into the process of compulsory purchase and the compensation mechanism to understand underlying causes for resistance. The purpose of this paper is to investigate the extent of involvement of these different stakeholders, at various stages in the compulsory purchase process, using stakeholder interaction analysis. Results obtained from this research will be helpful in identifying the gaps in the process of compulsory purchase of land for public projects in Australia.

Design/methodology/approach
A survey of ten different stakeholder groups has been conducted to inquire the level of interaction of different stakeholders at various stages of compulsory purchase process. A comparative study was then performed to identify the gaps between the advocated process (suggested in the literature) and the process adopted by stakeholders.

Findings
The results illustrate that: affected landowners seek involvement at the initial stage when the project plan is under preparation and compulsory purchase declaration are not finalised; objectors (from the public) seek opportunities to convey, to the public agency, their views even though the accountability of public agencies towards this stakeholder is nil; and strong interactions are established during negotiation over the compensation amount thus signifying the urge of acquirer and acquirees to avoid monetary losses and time delays.

Originality/value
This research will be useful in identification of pain points in the compulsory purchase process for public projects. This shall help in evolution of fairer mechanism of land acquisition.
The study of electrochemical synthesis, properties and composite mechanism of PANI/PVA and PANI/PVA/Ag composite films
Authors: Deng Shu-hao , Wang Yu , Yang Xi 
Published: January 2018

Purpose
The purpose of this paper is to improve the conductivity and processability of polyaniline (PANI).

Design/methodology/approach
The study opted for synthesis of the conductive PANI/polyvinyl alcohol (PVA) composite film, co-doped with 5-sulphosalicylic acid and sulphuric acid. Using an electrochemical method, a small amount of silver (Ag) was electrodeposited on the film. The PVA/PANI and PVA/PANI/Ag composite films were characterised by scanning electron microscope, X-ray diffraction and infrared. The composite deposition mechanism of the composite film was investigated by cyclic voltammetry for the first time.

Findings
The conductivity of the optimum PVA/PANI composite film reached 21.2 S · cm−1.Then, a small amount of Ag was deposited on the PVA/PANI film, and the conductivity significantly increased by 1250 S · cm−1. Through appropriate degree of stretching, the conductivity of the films was enhanced. The results indicate that uniform PVA/PANI fibres and dendritic Ag can combine to form complete three-dimensional conductive networks that exhibit better conductivity and mechanical properties. The cyclic voltammetry curves reveal that the dedoping potential of PANI was more negative than the reduction potential of Ag. Therefore, the procedure for the deposition of Ag on the PANI/PVA composite film cannot decrease the conductivity.

Practical implications
This paper for the first time described and revealed the effective and practical synthesis approach and composite mechanism to prepare multi-types metal-conductive polymer composites and improve the conductivity of a conductive polymer with a less expense and one-step electrochemical method.

Originality/value
This paper first explored galvanostatic oxidation to synthesise a PANI composite film to resolve the processability and conductivity of PANI by co-doped with mixed acids and deposited Ag on film. Furthermore, for the first time, the composite mechanism of metal and conductive polymer was studied.
Post-records survey inspections in Zimbabwe
Authors: Mutsagondo Samson 
Published: January 2018

Purpose
This paper aims to establish public departments’ compliance with National Archives of Zimbabwe (NAZ)’s records survey recommendations as well as to find out reasons for compliance and non-compliance.

Design/methodology/approach
This quantitative research used a survey research design and collected data using questionnaires, which were triangulated by document reviews and personal observation. A census approach was used where all 15 public departments upon which post-records survey inspections were conducted by Gweru Records Centre in the Midlands Province in 2016 were involved in the study.

Findings
The study revealed that many public departments in Zimbabwe disregarded records survey recommendations given by NAZ after records surveys. This was despite the fact that NAZ was armed with the National Archives of Zimbabwe Act (1986) which in principle is supposed to induce compliance by client departments. As a result, the records management situation in public departments has not improved much, and in some cases, it has become worse.

Originality/value
A lot has been published about records surveys in Zimbabwe, for example, by Chaterera (2008, 2013), Dewah (2010), Karimanzira and Mutsagondo (2015), Maboreke (2007) and Mutsagondo (2012). These studies have shown the importance of records surveys. However, none of them has evaluated the effectiveness of records surveys by examining the degree of compliance to records survey recommendations by public departments. This study thus scores a first in this regard. The study will enable NAZ to make a cost-benefit analysis of records surveys as well as to use results of this study to effect necessary operational, tactical and strategic decisions as regards the exercise.
A review of digital curation professional competencies: theory and current practices
Authors: Feng Yuanyuan , Richards Lorraine 
Published: January 2018

PurposeThe purpose of this paper is to examine the concept of professional competency in current digital curation literature through the lens of competency theories in management science and organizational studies. This paper also aims to provide recommendations to articulate and expand professional competencies in future digital curation research and professional education.Design/methodology/approachThe outcomes presented in this paper are based on a multi-disciplinary literature review and a qualitative content analysis. The literature review explores theoretical foundations of professional competency in management science and organizational studies and how the concept of professional competency is used in digital curation literature. The content analysis scrutinizes 16 digital curation publications that have discussed professional competency, with an in-depth examination of seven empirical studies in these publications.FindingsThe findings include: the concept of professional competency is inconsistently used in digital curation literature, the digital curation literature exhibits disparate coverage of different types of professional competencies, and the digital curation empirical studies often narrowly operationalize the concept of professional competency but the empirical studies using multiple or in-depth qualitative methods yield more comprehensive findings reflecting a broader scope of the concept.Originality/valueAlthough past research focused on the competencies required for digital curation, there is no research scrutinizing the conceptual construct of professional competency in the digital curation literature. This paper will be of value to digital curation researchers and educators to better determine the competencies needed for digital curators as an emerging profession.
Phytohormones, Isoprenoids, and Role of the Apicoplast in Recovery from Dihydroartemisinin-Induced Dormancy of Plasmodium falciparum
Authors: Duvalsaint Marvin , Kyle Dennis E. 
Published: January 2018

ABSTRACT

Many organisms undergo dormancy as a stress response to survive under unfavorable conditions that might impede development. This is observed in seeds and buds of plants and has been proposed as a mechanism of drug evasion and resistance formation in
Plasmodium falciparum
. We explored the effects of the phytohormones abscisic acid (ABA) and gibberellic acid (GA) on dihydroartemisinin (DHA)-induced dormant erythrocytic stages of
P. falciparum
parasites. Dormant ring stages exposed to ABA and GA recovered from dormancy up to 48 h earlier than parasites exposed to DHA alone. Conversely, fluridone, an herbicide inhibitor of ABA synthesis, blocked emergence from dormancy. Additionally, the role of the apicoplast was assessed in dormant parasite recovery. Apicoplast-deficient
P. falciparum
remained viable for up to 8 days without the organelle and recrudesced only when supplemented with isopentyl pyrophosphate (IPP). IPP was not required for survival in the dormant state. Fosmidomycin inhibition of isoprenoid biosynthesis did not prevent dormancy release from occurring in parasites with an intact apicoplast, but IPP or geranylgeranyl pyrophosphate was needed for complete recrudescence. In addition, the apicoplast and specifically the isoprenoids it produces are essential for recovery of dormant parasites. In summary, ABA and GA have significant effects on dormant parasites, and the phenotypes produced by these phytohormones and the herbicide fluridone also provide a means to explore the mechanism(s) underlying dormancy and the regulatory network that promotes cell cycle arrest in
P. falciparum
.
Aspergillus fumigatus
Afssn3-Afssn8
Pair Reverse Regulates Azole Resistance by Conferring Extracellular Polysaccharide, Sphingolipid Pathway Intermediates, and Efflux Pumps to Biofilm
Authors: Long Nanbiao , Zeng Liping , Qiao Shanlei , Li Lei , Zhong Guowei 
Published: January 2018

ABSTRACT

Antifungal treatment is often ineffectual, partly because of biofilm formation. In this study, by using a combined forward and reverse genetic strategy, we identified that nucleus-localized AfSsn3 and its partner AfSsn8, which constitute a Cdk8-cyclin pair, are required for azole resistance in
Aspergillus fumigatus
. Deletion of
Afssn3
led to increased absorption and utilization of glucose and amino acids. Interestingly, absorption and utilization of glucose accelerated the extracellular polysaccharide formation, while utilization of the amino acids serine, threonine, and glycine increased sphingolipid pathway intermediate accumulation. In addition, the absence of
Afssn3
induced the activity of the efflux pump proteins. These factors indicate the mature biofilm is responsible for the major mechanisms of
A. fumigatus
resistance to azoles in the Δ
Afssn3
mutant. Collectively, the loss of
Afssn3
led to two “barrier” layers between the intracellular and extracellular spaces, which consequently decreased drug penetration into the cell.
Single-Dose Pharmacokinetics and Safety of Meropenem-Vaborbactam in Subjects with Chronic Renal Impairment
Authors: Rubino Christopher M. , Bhavnani Sujata M. , Loutit Jeffery S. , Lohse Brooke , Dudley Michael N. , Griffith David C. 
Published: January 2018

ABSTRACT

Vaborbactam is a member of a new class of β-lactamase inhibitors with inhibitory activity against serine carbapenemases (e.g.,
Klebsiella pneumoniae
carbapenemase) that has been developed in combination with meropenem. The pharmacokinetics of the combination was evaluated in 41 subjects with chronic renal impairment in a phase 1, open-label, single-dose study. Subjects were assigned to one of five groups based on renal function: normal (creatinine clearance of ≥90 ml/min), mild (estimated glomerular filtration rate [eGFR] of 60 to 89 ml/min/1.73 m
2
), moderate (eGFR of 30 to <60), or severe (eGFR of <30) impairment plus end-stage renal disease (ESRD) patients on hemodialysis. Subjects received a single intravenous dose of 1 g of meropenem plus 1 g of vaborbactam by 3-h infusion. The ESRD group received two doses (on and off dialysis) separated by a washout. Pharmacokinetic parameters were estimated by standard noncompartmental methods. For both meropenem and vaborbactam, the area under the concentration-time curve was larger and the elimination half-life was longer with decreasing renal function. Meropenem and vaborbactam total plasma clearance (CLt) rates were similar and decreased with decreasing renal function. Slopes of the linear relationship between eGFR and CLt were similar, indicating a similar proportional reduction in CLt with decreasing renal function. Hemodialysis significantly increased drug clearance of meropenem (mean of 2.21-fold increase in CLt,
P
< 0.001) and vaborbactam (mean of 5.11-fold increase,
P
= 0.0235) relative to drug administration off dialysis, consistent with dose recovery rates of 38.3% and 52.9% for meropenem and vaborbactam, respectively, in dialysate. Plasma clearance of meropenem and vaborbactam is reduced with renal impairment, requiring dose adjustment. Hemodialysis removes both drugs.
