Social media advertisements with deposit contracts and fitness club/gym membership: are consumers persuaded?
Authors: Fogel Joshua , Ustoyev Sarah 
Published: November 2020

PurposeThis study aims to examine the association of social media advertising with deposit contracts and consumers joining a fitness club/gym.Design/methodology/approachThis paper surveyed 745 college students. Three deposit contract options were presented with goals of losing 5% of your original weight, losing 10 pounds from your weight and exercising for 75 min.FindingsThis paper found that consumers chose deposit contracts at higher rates than no contract or regular contract options. This paper found that behavioral control was positively associated with choosing a deposit contract. This paper found that presence of a weight problem was positively associated with choosing a deposit contract with very concrete goals of losing 10 pounds or exercising for 75 min while no association occurred for the less specific concrete goal of losing 5% of your original weight.Originality/valueIn conclusion, marketers can consider a novel advertising approach on social media of advertising deposit contract information to possibly interest consumers to join a fitness club/gym.

Published: November 2020

PurposeThe purpose of this study is to investigate efficiency and productivity of Turkey’s both brokerage sector and intermediary institutions (IIs) that have been active in Turkish capital markets.Design/methodology/approachData envelopment analysis (DEA) and Malmquist total factor productivity index (MPI) are used to analyze efficiency and productivity of Turkey’s both brokerage sector and 51 Turkish IIs constantly operated between the years 2008 and 2018. Paid-in capital, administrative expenses and trading volumes are used as input, while net trading commissions and net profit/loss are used as output in analysis. The calculations of this analysis are made with DEAP 2.2 program and Python.FindingsThe results reveal that during the analysis period, percentage of efficient institutions among 51 IIs was between 18% and 39% while the sector’s mean efficiency score ranged between 52% and 65%. While 2009 is the year with the highest number of efficient institutions, 2013 is observed to be the least. Finally, the results of productivity analysis indicate that all types of IIs are not fully productive during the related period. The striking finding obtained is that though there is a decrease in total productivity change, the technological change has a positive effect on their productivity change.Originality/valueThis study is a double-layered research paper that includes efficiency analysis by DEA in the first step and productivity analysis by using MPI in the second step.
Information experiences of Bangladeshi immigrants in Canada
Authors: Shuva Nafiz Zaman 
Published: November 2020

PurposeStudies on the information behaviour of immigrants including refugees across the globe show a significant dependency of immigrants on their informal networks for meeting various settlement and everyday life information needs. Although there are quite a few studies in LIS that globally report the dependency of immigrants on their personal networks, very little is known about their experiences with their informal personal networks in the contexts of their settlement in informational terms. This paper explores the information experiences of Bangladeshi immigrants in Canada consulting informal networks including broader Bangladeshi community people in pre- and post-arrival contexts.Design/methodology/approachThe study uses a mixed-method approach including semi-structured interviews (n = 60) and surveys (n = 205) with Bangladeshi immigrants who arrived in Canada between the years of 1971 and 2017. Interview data were analysed thematically, and descriptive statistics are used to describe the survey data relevant to this study.FindingsAlthough the overall scope of the original study is much larger, this paper features findings on the information experience derived from an analysis of the interview data with some relevant references to the survey data when deemed appropriate. This paper provides insights into the information experiences of Bangladeshi immigrants within their personal networks, including friends, family and ethnic community people. The findings of this study show that participants sometimes received discouraging, unhelpful or wrong information from their personal networks. The multiple dimensions of the information experiences of the study participants show the many consequences for their settlement lives. For some participants, settlement was particularly impacted by the concept of “information sharing fear” that emerged from the interviews. Information sharing fear relates to concerns that sharing information about the challenges faced by newcomers could be considered by potential immigrants as a kind of active “discouragement”. Participants described being sensitive to charges of envy or jealousy when they shared information related to challenges newcomers face, as friends and family see them as trying to prevent competition for social status.Originality/valueThe findings related to the information experiences of immigrants consulting informal networks has potential implications for research in various discipline such as LIS, migrational studies and psychology that explore the benefits of social networks in newcomers' settlement. The study also sets a ground to take a more holistic approach to the information experiences of newcomers, not just naming the sources newcomers utilize in settlement and everyday life contexts. The study also provides some future directions to comprehensively understand the culturally situated information behaviour of various immigrant groups.
African pathway to achieve inclusive growth: COMESA case study
Authors: Albagoury Samar H. 
Published: November 2020

Purpose
The relationship between economic growth performance and achieving inclusive growth, especially concerning poverty rate, is a subject of continuous argument in economic literature. Although some argue that this relationship is deterministic, i.e. achieving economic growth will definitely reduce poverty and enhance inclusive growth, others believe that the relationship between growth and poverty is conditional, depends mainly on the status of income distribution in this country, i.e. if the growth is combined with a significant improve in distribution then it will reduce poverty.

Design/methodology/approach
Africa is a clear example of the nexus between economic growth and poverty reduction. Although many African countries manage to achieve relatively high growth rates, hit two digits in some cases, during the last decades, poverty still widely spread in those countries. Of the 30 poorest countries in the world, 24 are African countries. And about 50% of African people still live under the poverty line. Common Market for Eastern and Southern Africa (COMESA), which could be considered as one of the fastest growing regions in Africa, is not an exception; although the region achieves relatively high growth rates, poverty and inequality are still among the region’s main development challenges.

Findings
This paper found that the economic growth rate achieved in COMESA countries could not be considered as inclusive growth as it does not combine with adequate enhancement in inclusiveness indicators. And that the structural characteristics of those countries economy and its inelasticity are the main reasons behind this inefficiency.

Originality/value
In this context, this paper aims to evaluate the effectiveness of economic growth achieved in COMESA countries in achieving inclusive growth and to identify the main factors affecting this relationship by using two steps data envelopment analysis. Although this method is originally developed to evaluate the relative economic efficiencies, the main contribution of this paper is the adaptation of data envelopment analysis to evaluate the efficiency of economic growth achieved in COMESA countries in enhancing inclusive growth dimensions such as poverty rate, inequality, unemployment, education, health, and then to identify in its second step the main indicators that could be used to explain the variation in efficiency scores.

Authors: Yang Jie , Chang Mingchao , Chen Zhihong , Zhou Lulu , Zhang Jiangjiang 
Published: November 2020

PurposeBased on the intrinsic motivation theory and spiritual leadership theory, the current study proposes a chain mediation model for testing the linkage between spiritual leadership and employees' innovative behavior through individual values and role identity.Design/methodology/approachIn this study, 309 valid leader–subordinate matching questionnaires from 10 Internet enterprises and 21 manufacturing enterprises in China were collected through a field study. The hypotheses were tested using structural equation modeling and bootstrapping.FindingsThe results show that spiritual leadership has a positive impact on employees' innovative behavior. Uncertainty avoidance and creative role identity not only respectively play a mediating role but also play a chain mediating role in the process of spiritual leadership influencing employees' innovative behavior.Originality/valueThis study explores the influence of leadership style on employees' individual values, which has rarely been done in previous studies. Furthermore, the research explores the impact of personal values (uncertainty avoidance) on employee self-perception (creative role identity). And it enriches the relationship between spiritual leadership and employees' innovative behavior and reveals the deeper influence mechanism between them.

Published: November 2020

Purpose
This study aims to report the design and testing of a maturity model for information and knowledge management in the public sector, intended for use in frequent monitoring, trend analysis and in-depth analysis of the contemporary information and knowledge management practices of an organization.

Design/methodology/approach
A design science approach was used to develop the proposed model. Creation of the model was based on an extensive literature review. Testing of the model was implemented as a survey receiving 37 responses from nine organizations organizing and purchasing public services.

Findings
The study presents four alternative profiles for an organization’s status, novice, experimenter, facilitator and advanced exploiter, and investigates the differences between these profiles on the basis of the empirical data gathered. The model was found to be both a valid and practical way to determine the state of an organization’s information and knowledge management and identify development needs.

Research limitations/implications
Testing was conducted in the Finnish public sector and further studies applying the model could be implemented in other countries. The model presented was designed specifically for the public sector and more research is needed to test its applicability in the private sector.

Originality/value
Maturity models are useful when evaluating information and knowledge management status in an organization, and beneficial for improving organizational performance. The proposed maturity model combines the fields of knowledge management and information management and contributes to the literature with an overarching maturity model that includes a dimension of satisfaction with the organizational maturity level. While many earlier models originate from the consultancy business, the model presented here was also designed for research purposes and tested in practice.
Humanitarian data justice: A structural data justice lens on civic technologies in post‐earthquake Nepal
Authors: Mulder Femke 
Published: November 2020

AbstractAs disasters are becoming increasingly datafied, social justice in the context of disasters is increasingly bound up with data. A data justice lens reveals how data projects and social justice interlink. This paper approaches social injustice in the context of disasters as structural inequalities in terms of resilience and risk. The first refers to people's ability to prevent, prepare for, respond to and recover from disasters, and the second to the probability that people will be exposed to hazards to which they are vulnerable. A data justice lens draws attention to the ways in which these structural inequalities shape humanitarian data projects. It also shows how such projects influence social justice outcomes. This paper shows how this lens can be applied to concrete disaster settings and the insights this yields for designers and project managers of data projects. This paper uses a qualitative case study approach to analyse two locally led civic technology projects in post‐earthquake Nepal. These progressive initiatives sought to give disaster‐affected people a role and a voice in the disaster response—and made a valuable contribution to response and recovery efforts. However, as they were rolled out in a context marked by stark social and digital inequalities, they still ended up primarily benefitting those who were relatively more resilient and less at risk. This paper explains why this happened and concludes by recommending critical and strategic collaboration with local progressive digital elites towards greater data justice in disaster settings.
The impact of perceived organizational support and job resourcefulness on supervisor‐rated contextual performance of firefighters: Mediating role of job satisfaction
Authors: Rubaca Ume , Majid Khan Muhammad 
Published: November 2020

AbstractDrawing on job demands‐resources model, we examined the positive impact of perceived organizational support and job resourcefulness on supervisor‐rated contextual performance of firefighters along with partial mediating effect of job satisfaction. We adopted a two‐wave survey technique to collect matched responses from 245 Pakistani firefighters about perceived organizational support, job resourcefulness and job satisfaction and 3 months later from their immediate supervisors on contextual performance. The results favour the importance of perceived organizational support and job resourcefulness as valuable resources for enhancing job satisfaction and in this way promote literature on job satisfaction. Results also endorsed job satisfaction as a partial mediator between organizational support, job resourcefulness and supervisor‐rated contextual performance of firefighters. We explored the complex motivational mechanism through which perceived organizational support and job resourcefulness affect supervisor‐rated contextual performance of firefighters. Results were consistent with the hypothesized model. Theoretical and practical implications are discussed.

Published: November 2020

SummaryConservation tillage in conjunction with straw mulching is a sustainable agricultural approach. However, straw mulching reduces the soil temperature, inhibits early maize growth and reduces grain yield in cold regions. To address this problem, we investigated the effects of inoculation of plant growth‐promoting rhizobacteria (PGPR) on maize growth and rhizosphere microbial communities under conservation tillage in Northeast China. The PGPR strains Sinorhizobium sp. A15, Bacillus sp. A28, Sphingomonas sp. A55 and Enterobacter sp. P24 were isolated from the maize rhizosphere in the same area and inoculated separately. Inoculation of these strains significantly enhanced maize growth, and the strains A15, A28 and A55 significantly increased grain yield by as much as 22%–29%. Real‐time quantitative PCR and high‐throughput sequencing showed that separate inoculation with the four strains increased the abundance and species richness of bacteria in the maize rhizosphere. Notably, the relative abundance of Acidobacteria_Subgroup_6, Chloroflexi_KD4‐96, and Verrucomicrobiae at the class level and Mucilaginibacter at the genus level were positively correlated with maize biomass and yield. Inoculation with PGPR shows potential for improvement of maize production under conservation tillage in cold regions by regulating the rhizosphere bacterial community structure and by direct stimulation of plant growth.

BackgroundPatients admitted to the Intensive Care Unit (ICU) often have low magnesium, phosphate and zinc levels. Monitoring of serum concentrations and supplementation may be important, but there is no consensus on optimal practice. The objective of the WhyTrace survey was to describe current practice regarding the measurement and supplementation of magnesium, phosphate and zinc in ICUs.MethodsA 54‐item electronic questionnaire was developed in accordance with SURGE, SUrvey Reporting GuidelinE, to address international clinical practice in the ICU. National investigators recruited ICUs in ten countries with one physician responding per ICU using a unique e‐mail distributed survey‐link.ResultsThe questionnaire was sent to clinicians in 336 ICUs of whom 283 (84%) responded. In 62% of the ICUs, a standard procedure was in place regarding the measurement of serum magnesium levels, in 58% for phosphate and in 9% for zinc. Zinc was never or rarely measured in 64% of ICUs. The frequency of requesting serum levels varied from twice daily to once weekly. Regarding supplementation, 66% of ICUs had a standard procedure for magnesium, 63% for phosphate and 15% for zinc. Most procedures recommended supplementation when serum levels were below the lower reference level, but some used the upper reference levels as the threshold for supplementation and others decided on a case‐by‐case basis.ConclusionThe practice of measuring and supplementing magnesium, phosphate and zinc differed substantially between ICUs. Our findings indicate that there is a need for high‐quality prospective data on frequencies of measurements, treatment goals and effects of supplementation on patient‐important outcomes.

BackgroundAlcohol (EtOH) intake during adolescence has become an important public health issue. Although the detrimental effects of EtOH intake on the musculoskeletal system are well known, only a few studies have investigated its impact on the stomatognathic system of adolescents. This study aimed to investigate the effect of EtOH binge drinking on the alveolar bone and the long‐term consequences after abstinence.MethodsAdolescent female Wistar rats (35 days old) were exposed to 4 cycles of EtOH binge drinking (3 g/kg/d; 3 days On‐4 days Off) or distilled water (control group). Alveolar bone micromorphology and vertical bone distance were evaluated at 1, 30, and 60 days after that last EtOH intake through X‐ray computed microtomography. The mineral:matrix ratio was assessed through Raman spectroscopy.ResultsA decrease in both trabecular thickness and volume ratio, and an increase in trabecular separation were observed at the 1‐day evaluation (immediate withdrawal). After 30 and 60 days, the alveolar bone parameters were found similar to control, except for the mineral:matrix ratio in the long‐term abstinence.ConclusionsEtOH binge drinking during adolescence results in alveolar bone damage that may persist in adulthood, even after abstinence.

The Arctic, one of the most sensitive components of the Earth's climate system, experienced pronounced climatic fluctuations during the Late Holocene. In order to obtain a detailed record of past environmental and climatic variability, sedimentary cores from two interconnected infilled depositional basins in the Kobbefjord area, southwestern Greenland, were retrieved and subjected to a multi‐proxy investigation. The absolute chronostratigraphy was established through radiocarbon (14C) and short‐lived radioisotope (210Pb,137Cs) dating. We also analysed magnetic susceptibility, grain size, X‐ray fluorescence element composition, total content of carbon, nitrogen and sulphur, biogenic silica and diatom assemblages. The palaeoenvironmental reconstruction presented from the upper basin records ~800 years of sedimentation in a former shallow Arctic lake/pond that was modulated by catchment processes and regional hydroclimate. The record is dominated by alternating periods of increased organic and clastic deposition, suggesting warmer/drier and colder/wetter climate, respectively. Comparison of our records with other proxy‐based lacustrine, marine and glacier records and instrumental measurements from Greenland and the North Atlantic reveals common climatic trends, consistent with the inferred North Atlantic Oscillation pattern. Periods at ~800–600, ~320–220 and ~140–30 cal. a BP correspond to the main cold phases. The earliest climatic deterioration coincides with the demise of the nearby Norse Western Settlement. The most recent cold period represents the culmination of the Little Ice Age with the maximum Holocene advances of Greenland glaciers. Ameliorated conditions predominated at ~550–320 and ~220–140 cal. a BP. The evolution of both water bodies is concluded by transition into oligotrophic peat bogs after complete infilling of the basins at ~30 cal. a BP. Despite differences in proxy signals between the coring sites, this study endorses the usefulness of shallow lake/pond sediments from infilled basins for environmental reconstructions, as long as local depositional processes do not mask the external driving factors.
