Authors: Nathoo Amaan , Bekaroo Girish , Gangabissoon Tanveer , Santokhee Aditya 
Published: February 2020

Purpose
This paper aims to explore the use of tangible user interfaces for teaching concepts related to internet of things by focusing on two aspects, notably, usability and learning effectiveness.

Design/methodology/approach
To assess the usability of IoTTT, Nielsen’s principles were used due to its relevance and popularity for usability assessment. In the usability questionnaire, four attributes were evaluated, notably, learnability, efficiency, errors and satisfaction. As for evaluating learning effectiveness, learning assessment was conducted through pre-tests and post-tests. Two groups of 20 students participated where the first group attended conventional lectures on IoT, whereas the second group used IoTTT for learning same concepts. In the process, data was collected through the usability questionnaire and tests for usability and learning effectiveness assessment.

Findings
Results revealed a positive score for the usability of the TUI solution with an average rating of 3.9. Although this score demonstrated an acceptable solution, different issues were identified, based on which a set of recommendations have been made in this paper. On the other hand, in the common pre-tests, an average score of 6.40 was obtained as compared to a mean score of 7.33 in the post-tests for all participants. Knowledge gains were significantly higher for students who learnt IoT concepts through the TUI-based system where performance improved by 18 per cent.

Originality/value
The results revealed in this study are expected to help the research community, course designers and tutors comprehend the prospects of using tangible user interfaces to foster teaching and learning of IoT concepts. In addition, educational solution providers could consider commercialisation prospects of this technology to innovate in teaching and learning, while also building-up on limitations identified within this study.
Consumer legitimacy: conceptualization and measurement scales
Authors: Randrianasolo Arilova A. , Arnold Mark J. 
Published: February 2020

PurposeThis paper aims to propose the concept of consumer legitimacy, develops scales to measure this concept and shows its utility and relevance in the international marketing field.Design/methodology/approachA four-step deductive approach (construct definition, item generation, scale purification and scale validation) is used to develop scales for three dimensions of consumer legitimacy, then a structural model of antecedents and outcomes of the construct provides validity for the developed scales.FindingsResults validate the developed scales with different multinational enterprise contexts across two countries. It is found that perception of social responsibility influences three dimensions of consumer legitimacy, both moral and cognitive legitimacy influence willingness to buy firm products, and moral legitimacy influences attitudes toward the firm.Practical implicationsAs a crucial resource, legitimacy can offer firms comparative advantages that lead to competitive advantages. The findings of this research provide a new perspective on how firms may measure, acquire and/or increase this resource.Originality/valueThis paper shifts the discussion of legitimacy to a key firm stakeholder that has been ignored in the literature: consumers. Thus, it implies that both researchers and practitioners should provide stronger consideration to the consumer role in granting legitimacy.
How does foreign direct investment affect growth in sub-Saharan Africa? New evidence from threshold analysis
Authors: Ibhagui Oyakhilome 
Published: February 2020

PurposeThe threshold regression framework is used to examine the effect of foreign direct investment on growth in Sub-Saharan Africa (SSA). The growth literature is awash with divergent evidence on the role of foreign direct investment (FDI) on economic growth. Although the FDI–growth nexus has been studied in diverse ways, very few studies have examined the relationship within the framework of threshold analysis. Furthermore, even where this framework has been adopted, none of the previous studies has comprehensively examined the FDI–growth nexus in the broader SSA. In this paper, within the standard panel and threshold regression framework, the problem of determining the growth impact of FDI is revisited.Design/methodology/approachSix variables are used as thresholds – inflation, initial income, population growth, trade openness, financial market development and human capital, and the analysis is based on a large panel data set that comprises 45 SSA countries for the years 1985–2013.FindingsThe results of this study show that the direct impact of FDI on growth is largely ambiguous and inconsistent. However, under the threshold analysis, it is evident that FDI accelerates economic growth when SSA countries have achieved certain threshold levels of inflation, population growth and financial markets development. This evidence is largely invariant qualitatively and is robust to different empirical specifications. FDI enhances growth in SSA when inflation and private sector credit are below their threshold levels while human capital and population growth are above their threshold levels.Originality/valueThe contribution of this paper is twofold. First, the paper streamlines the threshold analysis of FDI–growth nexus to focus on countries in SSA – previous studies on FDI-growth nexus in SSA are country-specific and time series–based (see Tshepo, 2014; Raheem and Oyınlola, 2013 and Bende-Nabende, 2002). This paper provides a panel analysis and considers a broader set of up to 45 SSA countries. Such a broad set of SSA countries had never been considered in the literature. Second, the paper expands on available threshold variables to include two new important macroeconomic variables, population growth and inflation which, though are important absorptive capacities but, until now, had not been used as thresholds in the FDI–growth literature. The rationale for including these variables as thresholds stems from the evidence of an empirical relationship between population growth and economic growth, see Darrat and Al-Yousif (1999), and between inflation and economic growth, see Kremer et al. (2013).
Predictors of patients' knowledge, attitudes and practices (KAP) regarding uncomplicated malaria in the primary healthcare facilities of Plateau state, Nigeria
Authors: Jimam Nanloh Samuel , Ismail Nahlah Elkudssiah 
Published: February 2020

PurposeThis study determined factors that influenced patients' knowledge, attitudes and practices (KAP) regarding uncomplicated malaria in primary healthcare (PHC) facilities of Plateau state, Nigeria.Design/methodology/approachThe data of 956 patients treated for uncomplicated malaria in PHC facilities of Plateau state were used for the study. Inferential statistical analyses were conducted to identify factors that influenced patients' KAP on the disease and its management.FindingsThe study revealed age (p < 0.001), level of education (p = 0.012), attitudes (p = 0.007) and practices (p < 0.001) as significant predictors of knowledge outcomes on uncomplicated malaria, while their attitudes towards the disease and its management was predicted by their gender (p = 0.011), occupation (p = 0.049), monthly income (p = 0.018), knowledge (p < 0.001) and practices (p < 0.001). Furthermore, their practices were significantly predicted by monthly incomes (p = 0.043), knowledge (p < 0.001), attitudes (p < 0.001) and number of anti-malarial and adjunct drugs administered to them (p = 0.041).Originality/valueThe study revealed a mixed influence of patients' characteristics on their KAP outcomes. This calls for appropriate intervention measures towards achieving the desired patients' therapeutic outcomes.
How do features of social media influence knowledge sharing? An ambient awareness perspective
Authors: Zhao Yuqing , Zhang Xi , Wang Jingyi , Zhang Kaihua , Ordóñez de Pablos Patricia 
Published: February 2020

Purpose
The purpose of this paper is to verify the relationship between the features of social media and knowledge sharing, and to examine how ambient awareness mediates this relationship.

Design/methodology/approach
An experiment is designed to stimulate the knowledge work in a famous Chinese business college and 156 valid samples were obtained. AMOS was used in this paper to examine the theoretical model.

Findings
There is a correlation among features of social media, ambient awareness and knowledge sharing. Surprisingly, network translucence, which indicates individuals’ meta-knowledge of others’ connections, has no influence on knowledge sharing. Although this is inconsistent with conjecture of the existing literature, it can be well explained by the phenomenon in real life, such as privacy setting in social media.

Practical implications
For employees who use social media to promote knowledge sharing within organizations, this study reminds them of the importance of ambient awareness. For managers, this study can give them some suggestions to make employees take full advantage of social media to achieve optimal benefits of knowledge sharing, thus improving organizational performance and innovation. For social media designers, they can make social media more useful in knowledge work by improving its specific features.

Originality/value
This paper proposes that ambient awareness is the mediator of the effect path between communication and knowledge sharing. And the status perception of coworkers’ exchanging information is closely related to knowledge sharing.
Implementing sustainable procurement in the United Arab Emirates public sector
Authors: Al Nuaimi Bader Khamis , Khan Mehmood , Ajmal Mian 
Published: February 2020

Purpose
Despite making significant strides in transforming its environmental outlook over the past few years and promoting sustainable procurement (SP) in the public sector, the United Arab Emirates (UAE) is still facing serious challenges in moving up the global sustainability ranks. Thus, this study aims to assess and prioritize critical factors, including cost, organization, innovation capability, stakeholder, culture and market-related factors, and their respective sub-factors for the implementation of SP, and come up with recommendations.

Design/methodology/approach
This study uses the analytical hierarchy process model to prioritize the main factors and sub-factors that can critically affect the implementation of SP in the UAE public sector. Data were collected through a survey of 17 procurement experts working in procurement departments in public organizations in Abu Dhabi, UAE.

Findings
The results reveal that cost is the highest ranked critical factor, followed by an organization, whereas innovation capability is the lowest ranked of the main factors. The initial cost of green products and their life-cycle cost are the most prioritized of cost factors. An individual’s commitment to change, top management support and organizational commitment are the highest-ranked sub-factors. Social awareness is the most important sub-factor among culture, and the supplier’s capability is the highest ranked sub-factor in the market.

Social implications
The government should issue a standard practices handbook for SP to be used by public organizations to provide public procurers a clear method for conducting a proper cost–benefit analysis to evaluate and decide on sustainable purchases that fit the economy and society and meet the national sustainability agenda. Furthermore, additional attention needs to be paid to cultural factors such as social and environmental awareness by policymakers to succeed in achieving SP. Finally, top management and government officials must reevaluate their own personal values and commitment to sustainability issues as they participate in forming policies, rules, regulations and training programs designed for procurement managers within government organizations.

Originality/value
Although considerable research has been conducted on this topic, this study is unique in its presentation of a critical understanding of which factors and sub-factors are likely to significantly affect SP implementation in the UAE, which shall provide the relevant researchers and practitioners with the necessary knowledge to be ready for the changes that may lie ahead.
Research on the impact of academic libraries – areas, methods, indicators
Authors: Głowacka Ewa 
Published: February 2020

Purpose
The purpose of this paper is to indicate the place of assessment of the impact of libraries in the overall quality evaluation of these institutions. In the paper, an attempt has been made to separate the concepts of the impact and values of library services and, according to the designated scope, the most important areas of research, methods and indicators for the assessment of the impact of academic libraries were characterized. The focus was on the most important areas, i.e. on the impact of libraries on didactics and academic research, information literacy and on its assessment in the cultural and environmental aspect.

Design/methodology/approach
A literature-based overview of actual insights on tasks and areas, methods, indicators research on the impact of academic is provided.

Findings
The author has determined that the analysis of the impact of academic libraries can mainly concern the following areas: information (influence on didactics, research and information competence of users), cultural and environmental. That is why it is worth analyzing the most important methods and indicators of research on the impact of academic libraries in these areas. The best way to research the quality of libraries, and especially to determine its impact on users and the environment, is to use a mixed methodology – a whole set of quantitative and qualitative methods and techniques. Triangulation can involve the use of both qualitative and quantitative data or the use of multiple methods to develop one type of data.

Research limitations/implications
However, these methods were used to study the impact of academic libraries, whose results do not determine the financial value.

Practical implications
The paper shows the methods of research on the quality of the functioning of academic libraries with a special emphasis on the study of their impact on users and the social environment.

Social implications
The paper shows the methodology of determining the social role of academic libraries.

Originality/value
The paper intends to add to the body of knowledge about the research methodology for the impact of academic libraries.
What drives people to participate in online firestorms?
Authors: Gruber Maria , Mayer Christiane , Einwiller Sabine A. 
Published: February 2020

PurposeSocial media empower individuals to voice their opinions about issues that they perceive to be unacceptable. When many others add their opinions and large quantities of messages containing negative word-of-mouth suddenly spread online, an online firestorm occurs. By extending the situational theory of problem solving (Kim and Grunig, 2011) into the domain of online communication, this study aims to identify the drivers for participating in online firestorms.Design/methodology/approachWith reference to a fictitious online firestorm trigger (i.e. perceived moral misconduct) posted on Facebook, a qualitative pre-study and quantitative online survey were conducted. Based on the responses of 410 participants, an ordinary least squares regression was modeled to examine the factors of participating in the online firestorm. Later, structural equation modeling was applied to test the model and gauge its fit with the data.FindingsParticipants' involvement recognition, perception of being collective actors and approval of slacktivism behaviors positively predicted their participation in the online firestorm, whereas non-anonymity hampered it.Originality/valueThe study's findings not only contribute to the current understandings of online firestorms but are also valuable for developing theory and forms of professional crisis management. Moreover, they offer insights into the factors of online communication environments that encourage users to voice their opinions.

Influence of dietary intake and decision‐making during pregnancy on birth outcomes
Authors: James‐McAlpine Janelle M. , Vincze Lisa J. , Vanderlelie Jessica J. , Perkins Anthony V. 
Published: February 2020

AbstractAimThis study aimed to examine dietary intake and decision‐making in a cohort of pregnant South‐East Queensland women to determine compliance with dietary guidelines and the relationships between dietary intake, decision‐making and birth outcomes.MethodsPregnant women attending maternity services at participating hospitals reported food frequency and motivations using the Maternal Outcomes and Nutrition Tool, a novel digital instrument. Birth outcomes were sourced from hospital records. A cross‐sectional cohort design was used to examine the data.ResultsAnalysis demonstrated suboptimal intake of core food groups; meat and alternatives (median [IQR]) (2.6 [2.0‐3.4] serves/day) and grains (3.1 [2.1‐4.1]) fell below recommendations; fruit (3.8 [2.5‐5.3]) and discretionary foods (3.1 [2.1‐4.4]) exceeded them. Hypertensive disorders demonstrated a negative linear relationship with vegetable intake (P = .017). Cultural diversity was significantly associated with decreased birthweight (P= .022) but increased intake of meat and alternatives (3.1 vs 2.6,P < .001) compared to Caucasian women; median intake of meat and alternatives was lower in women who reported smoking in the examined time frame. Smokers were less likely to declare health motives for food selection than non‐smokers; smoking and health were inversely associated with increasing maternal age. Food choice was primarily sensory‐driven.ConclusionsThis cohort demonstrated poor adherence to dietary guidelines. Culturally and linguistically diverse women and smokers exhibit dietary behaviours which may contribute to suboptimal birth outcomes; targeted nutrition counselling may improve outcomes in these women. These findings highlight the need for transdisciplinary maternity care and provide a foundation for further research aimed at optimising nutrition‐related birth outcomes in at‐risk groups.

Published: February 2020

AbstractMosquitoes can transfer many adverse diseases to human and animals therefore, there is a need to fight their spread. Among promising larvicidal sources is the use of plant extracts, which will play an important role in the future. This study was conducted to assess the larvicidal activity of Ferula hermonis Boiss,Achillea millefolium, Salvia officnalis, Psidium guaja and Matricaria chamomilla extract against Culex pipiens. The plant materials were extracted with hexane, dichloromethane, ethyl acetate, and methanol using a Soxhlet extractor. The extracts were evaluated for larvicidal activity against Cx. pipiens the mortality was monitored after 24 and 48 h of exposure. None of the extracts tested showed larvicidal acitivties except M. chamomilla. The ethyl acetate extract showed the most promising larvicidal activity with LC50 values of 287.1 and 209.4 ppm after 24 and 48 h of exposure, respectively. Treatment of the eggs with different concentrations of the active extract decreased the hatchability of the eggs dose dependently from 95 to 86.49%. Similarly, the pupal duration increased in treated groups. The larval period lasted for 12 d, whereas that of the control group lasted for 10 d. Furthermore, the pupal period lasted 3 d (control 2 d) in treated groups. The data also revealed a significant decrease in the growth index in treated groups (0.00–7.53) than that of the control (8.5). The GC–MS analysis revealed the presence of 1.6.10‐dodecatriene, 7,11‐dimethyl‐3‐methylene (89.68%), 1,6‐cyclodecadiene, 1‐methyl‐5‐methylene‐8‐(1‐methylethyl)‐, [S‐(E,E)] (6.34%), 2H‐pyran −3‐ol (4.04%), and 2H‐1‐benzopyran‐2‐one (0.079%).
