Authors: Remøy Hilde , Rovers Sander , Nase Ilir 
Published: March 2019

PurposeThe purpose of this paper is to develop an operational framework with guidelines and lessons to improve the current real estate portfolio disposal procedures of freeholds, based on empirical evidence from the banking sector.Design/methodology/approachThe empirical research is based on a comparative analysis of four case studies, representing approximately 80 per cent of the Dutch banking sector. The case studies comprise a systematic document review of corporate business and real estate strategies and semi-structured interviews with decision makers who steer the organisation’s corporate real estate (CRE) portfolio composition.FindingsThis research shows a strong relationship between organisation characteristics, legacy and strategy, disposal drivers and CRE disposal strategies. The weighing of drivers and order of steps in strategy execution strategies largely depend on organisational objectives.Research limitations/implicationsThis paper reports empirical findings from Dutch case studies. To generalise, further research is needed in different legal, financial and economic contexts and in other sectors. This paper suggests a more thorough study of the relationship between space-use efficiency and technological innovation implementation..Practical implicationsThe framework proposes strategy improvements and a proactive approach to corporate real estate management (CREM) to create value through real estate portfolios.Originality/valueThis paper provides a thorough analysis of the CREM of the Dutch banking sector and is applicable to CREM in this and other sectors.
RFID use in residential/commercial construction industry
Authors: Kereri James Ogechi , Adamtey Simon 
Published: March 2019

Purpose
In the past decade, radio frequency identification devices (RFIDs) have attracted the attention of the construction industry, having been proven to be an effective technology for addressing operational challenges in other industries such as health-care, retail and manufacturing. Despite the benefits, the use of RFID in construction industry is limited even in the face of inefficiencies that exist and that the need for improvement is yet to drive the widespread adoption in the residential/commercial construction industry. The purpose of this study is to investigate key drivers and critical success factors for RFID adoption.

Design/methodology/approach
The study included extensive and systematic literature review, interviews and questionnaire survey.

Findings
The study revealed that the most important key driver for RFID adoption is productivity improvement, while the most important critical success factors include management support and commitment, having clear RFID strategy, needs and benefits, having strong motivation for improvement, providing adequate funding and proper planning.

Practical implications
This study provides an exploratory framework that can be used by construction company executives and managers to provide justification for deciding to implement RFID on their projects and to enhance success rates of implementation.

Originality/value
This study contributes to the knowledge on RFID use in residential/commercial construction industry and provides a basis for further investigation by construction management researchers on the emerging issues regarding RFID use in the construction industry.
Effects of calcium leaching on the physical and mechanical properties of aerial lime-cement mortars
Authors: Bellifa Soufyane , Boumechra Nadir 
Published: March 2019

Purpose
This paper aims to assess the effects of chemically accelerated leaching on the physical and mechanical properties of aerial lime–cement mortars (LCMs).

Design/methodology/approach
Two aerial LCMs, differencing mainly in their calcium hydroxide content, were degraded by the use of an ammonium nitrate solution as a leaching agent. The leaching effects were studied by evaluating the rate of change in physical (sorptivity and mass loss) and mechanical (flexural and compressive strength) characteristics of aerial LCMs. To quantify the evolution and kinetics of degradation, the leached depth was then characterized at different levels of degradation by means of a phenolphthalein solution.

Findings
The experimental results showed that the dissolution of binder decreases the mass, alkalinity and strength of aerial LCMs but increases their sorptivity. A linear relationship was derived by plotting the values of leached depth against the square root of immersion time in an aggressive solution. It was found that the leached depth followed diffusion-controlled kinetics.

Originality/value
It was found that the global loss of compressive strength of aerial LCMs because of complete dissolution of calcium hydroxide can reach up to 80 per cent.

Authors: Sampoon Kwanrutai , Posri Nuengruethai , Kittichotpanich Boonsri 
Published: March 2019

Purpose
The purpose of this paper is to test the effectiveness of social dance exercise and social support program to improve quality of life (QOL) for older adults in Thailand.

Design/methodology/approach
A quasi-experimental pre-test and post-test research design was used. The participants were 102 older adults selected by systematic sampling technique. Participants were assigned using the matched-pair technique by age, physical fitness test by the Time up and Go test into intervention and control groups of 51 subjects each. Intervention was conducted for 12 weeks, three times weekly, to improve physical, psychosocial and spiritual domains leading to enhanced QOL as measured by the World Health Organization Quality of Life (WHOQOL–BREF–THAI) assessment parameter. Data on QOL were collected before and after a 12-week training period.

Findings
Most adults were between 70 and 79 years old (67 percent). After program completion, before and after mean QOL scores for the intervention group at 60.15 and 95.82, respectively, were statistically significant with p-value<0.05. Post-program QOL shown by the intervention group was significantly higher than the control group (p<0.05).

Originality/value
Application of social dance exercise and social support program is an alternative to traditional methods to improve QOL and maintain functional capacity for older adults.
Can shared leadership enhance clinical team management? A systematic review
Authors: Aufegger Lisa , Shariq Omair , Bicknell Colin , Ashrafian Hutan , Darzi Ara 
Published: March 2019

Purpose
Research in psychology or management science has shown that shared leadership (SL) enhances information sharing, fosters participation and empowers team members within the decision-making processes, ultimately improving the quality of performance outcomes. Little has been done and, thus, less is known of the value and use of SL in acute healthcare teams. The purpose of this study is to (1) explore, identify and critically assess patterns and behaviour of SL in acute healthcare teams; and (2) evaluate to what extent SL may benefit and accomplish safer care in acute patient treatment and healthcare delivery.

Design/methodology/approach
The authors conducted a review that followed the PRISMA-P reporting guidelines. A variety of sources were searched in April 2018 for studies containing primary research that focused on SL in acute healthcare teams. The outcome of interest was a well-specified assessment of SL, and an evaluation of the extent SL may enhance team performance, lead to safer patient care and healthcare delivery in acute healthcare teams.

Findings
After the study selection process, 11 out of 1,383 studies were included in the review. Studies used a qualitative, quantitative or mixed-methods approach. Emerging themes based on behavioural observations that contributed to SL were: shared mental model; social support and situational awareness; and psychological safety. High-performing teams showed more SL behaviour, teams with less seniority displayed more traditional leadership styles and SL was associated with increased team satisfaction.

Research limitations/implications
Evidence to date suggests that SL may be of benefit to improve performance outcomes in acute healthcare team settings. However, the discrepancy of SL assessments within existing studies and their small sample sizes highlights the need for a large, good quality randomized controlled trial to validate this indication.

Originality/value
Although studies have acknowledged the relevance of SL in healthcare service and delivery, a systematic, evidence-based and robust evaluation of behavioural patterns and the benefits of SL in this field is still missing.

Published: March 2019

PurposeThe purpose of this paper is to examine the relationships among choice of industry diversification, capabilities and business group performance, as well as to point out the potential concern about endogenous role of industry diversification.Design/methodology/approachUsing data from the top 100 business groups in Taiwan from TEJ database. This study uses Heckman’s two-step estimation procedure and contingency model to achieve unbiased results and examine our hypotheses.FindingsThe results of this study find that if business groups’ marketing or operational capabilities are strong they should adopt a high level of diversification strategy and if business groups’ R&D capability is strong they should adopt a low level one. The results of this study also show that the endogenous problem of industry diversification exists, and needs to be considered. Moreover, our finding confirms the importance of capability–strategy fit, which, in turn, can achieve better performance.Practical implicationsOn average, high industry diversification groups perform better than low industry diversification groups after controlling for endogeneity issues. Business groups can achieve better performance if their strategy choices match the capabilities they encounter. Managers should pay attention to strategy-capability fit issues. Specifically, they should review their organizational capabilities as well as check their strategies within firms.Originality/valueThis study is one of the first that attempts to explore the endogenous role of diversification strategy choices, and empirical examine strategy-capability fit on business group performance.
Instafamous and social media influencer marketing
Authors: Jin S. Venus , Muqaddam Aziz , Ryu Ehri 
Published: March 2019

Purpose
The purpose of this paper is to test the effects of two types of celebrities (Instagram celebrity vs traditional celebrity) on source trustworthiness, brand attitude, envy and social presence. The proposed theoretical model consists of the celebrity type as the independent variable, social presence as the mediator and self-discrepancy as the moderator.

Design/methodology/approach
A randomized two-group comparison (Instagram celebrity vs traditional celebrity) between-subjects experiment (n=104) was conducted.

Findings
The results indicate that consumers exposed to Instagram celebrity’s brand posts perceive the source to be more trustworthy, show more positive attitude toward the endorsed brand, feel stronger social presence and feel more envious of the source than those consumers exposed to traditional celebrity’s brand posts. Structural equation modeling (Mplus 8.0) and bootstrap confidence intervals indicate that social presence mediates the causal effects of celebrity type on trustworthiness, brand attitude and envy. Multiple regression analyses reveal the moderating effects of appearance-related actual–ideal self-discrepancy.

Practical implications
Ultimately, managerial implications for social media marketing and Instagram influencer-based branding are provided. From the perspective of marketing planning, the findings speak to the power of influencer marketing as an effective branding strategy.

Originality/value
The paper discusses theoretical implications for the marketing literature on celebrity endorsements.
The influence of logging on vertebrate responses to mast fruiting
Authors: Granados Alys , Bernard Henry , Brodie Jedediah F. 
Published: March 2019

AbstractPeriods of extreme food abundance, such as irregular masting events, can dramatically affect animal populations and communities, but the extent to which anthropogenic disturbances alter animal responses to mast events is not clear. In South‐East Asia, dipterocarp trees reproduce in mast fruiting events every 2–10 years in some of the largest masting events on the planet. These trees, however, are targeted for selective logging, reducing the intensity of fruit production and potentially affecting multiple trophic levels.Moreover, animal responses to resource pulse events have largely been studied in systems where the major mast consumers have been extirpated. We sought to evaluate the influence of human‐induced habitat disturbance on animal responses to masting in a system where key mast consumers remain extant.We used motion‐triggered camera traps to quantify terrestrial mammal and bird occurrences in Sabah, Malaysian Borneo, relative to variation in fruit biomass from 69 plant families during a major (2014) and minor (2015) masting event and a non‐mast year (2013), in both logged and unlogged forests.Bearded pigs (Sus barbatus) showed the clearest responses to masting and occurrence rates were highest in unlogged forest in the year following the major mast, suggesting that the pulse in fruit availability increased immigration or reproduction. We also detected local‐scale spatial tracking of dipterocarp fruits in bearded pigs in unlogged forest, while this was equivocal in other species. In contrast, pigs and other vertebrate taxa in our study showed limited response to spatial or temporal variation in fruit availability in logged forest.Our findings suggest that vertebrates, namely bearded pigs, may respond to masting via movement and increased reproduction, but that these responses may be attenuated by habitat disturbance.
Plant biomass, rather than species composition, determines ecosystem properties: Results from a long‐term graminoid removal experiment in a northern Canadian grassland
Authors: Melendez Gonzalez Mayra , Crofts Anna L. , McLaren Jennie R. 
Published: March 2019

Abstract

Human‐induced environmental change is occurring globally and alters ecosystem properties both directly, by changing abiotic conditions, and indirectly, by modifying community composition. The effects of changes in plant composition in determining ecosystem properties may be determined by the identity of the plants, their respective biomass in the community and also by the ability of remaining vegetation to compensate for their loss.

We used the graminoid removal treatment from a long‐term (12 year) removal experiment to examine the role of graminoids in determining ecosystem properties and also the potential for biomass compensation by remaining species in a grassland in northern Canada. We conducted removals in both fertilized and non‐fertilized environments to examine context‐dependency of graminoid effects.

There was full biomass compensation for graminoid removal by the remaining functional groups (i.e., total biomass was equal to no‐removal controls) after 5 years, and after 12 years fertilized plots showed overcompensation for removals.

After 12 years of graminoid removals, most ecosystem properties were not affected by removals in either fertilization environment. Similarly, there were few effects on microbial biomass or function with plant removal or fertilization treatments.

Comparison to earlier published responses in this experiment shows a strengthening of the responses of the plant community to graminoid removals over time while effects on ecosystem properties diminished. Full biomass compensation for removal of graminoids occurred after 5 years, and after 12 years of removals, fertilized plots had overcompensated for the loss of graminoids. In contrast, the shorter term (4 years) responses of soil available nutrients and soil moisture to removals have mainly disappeared after eight further years, likely because of the biomass compensation by the plant community.

Synthesis. Comparing the effects of graminoid removals on ecosystem structure and function after 4, 7, and now 10 and 12 years of removals, we now argue that, after over a decade of graminoid removal, recovery of plant biomass is required for the maintenance of most ecosystem properties and not functional group identity, as we concluded earlier. This highlights the importance of maintaining field experiments in the long term, particularly in northern ecosystems.
Children Diplomacy During the Late Cold War: Samantha Smith's Visit of the ‘Evil Empire’
Authors: NEUMANN MATTHIAS 
Published: March 2019

AbstractSamantha Smith came to fame by writing a letter to the Soviet leader, Yuri Andropov, in December 1982, expressing her fears about a potential nuclear war between the two superpowers. Her letter was quoted in the main Soviet newspaper Pravda in April 1983 and the Smith family was subsequently invited to visit the Soviet Union during the summer. Samantha's trip captured the attention of the world media on both sides of the ideological divide. However, her trip has usually been dismissed as a quirky footnote in Cold War history. Scholarly interest has only just begun, sparked by the growing research into the significance of citizen diplomacy, which saw a real explosion in the late Cold War. This article will demonstrate that Samantha Smith's trip was a pivotal moment in this broader process because it provided a very public challenge to the strong political discourse of the early Reagan administration, which promoted conflict. Based on an analysis of Soviet and American media reporting, and using hitherto unused archival evidence, as well as oral history interviews, this article examines why and how Samantha Smith became an icon of citizen diplomacy in the early 1980s. Analysing the receptions, representations and legacies of her trip on both sides of the ideological divide, it will shed fresh light on the role of children as soft power during the Cold War and highlight Samantha Smith's role as a precursor of a rapidly expanding citizen diplomacy that played a largely ignored part in bringing the conflict to an end.

ObjectiveTo evaluate the burden, causes and outcomes of severe non‐obstetric maternal complications in Nigerian public tertiary hospitals.DesignSecondary analysis of a nationwide cross‐sectional study.SettingForty‐two tertiary health facilities.PopulationWomen admitted with complications during pregnancy, childbirth or puerperium.MethodsAll cases of severe maternal outcome (SMO: maternal near‐miss or maternal death) due to non‐obstetric causes were prospectively identified over a 1‐year period. Maternal near‐miss was defined using organ‐system dysfunction (WHO), clinical, or management‐based criteria.Main outcome measuresCauses and contributions of non‐obstetric complications to SMO; fetal and neonatal outcomes; health service events associated with non‐obstetric complications; and mortality index (% of maternal death/SMO).ResultsOf 100 107 women admitted with complications, 9401 (9.4%) were for non‐obstetric causes; and 4.0% (375/9401) suffered severe non‐obstetric complications. Of the 375 cases of severe non‐obstetric complications, 48.8% (183/375) were near‐misses and 51.2% (192/375) were maternal deaths. Severe anaemia unrelated to haemorrhage contributed 61.2% of near‐misses and 32.8% of maternal deaths. The highest mortality indices were observed for cancer (91.7%), hepatic diseases (81.8%) and HIV/AIDS/HIV wasting syndrome (80.4%). Fatality was significantly high with extremes of age and no formal education. Regarding organ dysfunctions, neurological (77.1%) and cardiovascular (75.0%) dysfunctions had the highest mortality indices. Perinatal mortality was 65.9%. Time from diagnosis of severe non‐obstetric complications to review by senior medical personnel, and to definitive intervention was <30 minutes in 30.2% and 29.8% of women with SMO, respectively. However, over 240 minutes elapsed between diagnosis and definitive intervention in more than one‐third of women with SMO.ConclusionNon‐obstetric complications are associated with poorer pregnancy outcomes and deserve attention similar to that accorded obstetric complications.FundingThe original research that generated the data for this secondary analysis and the publication of this secondary analysis were funded by the UNDP‐UNFPA‐UNICEF‐WHO‐World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), a co‐sponsored programme executed by the World Health Organization (WHO).Tweetable abstractNon‐obstetric causes are important contributors to maternal deaths and life‐threatening morbidities in Nigerian hospitals.

Published: March 2019

AbstractWe present a systematic review of the extensive body of research on farmer risk preference measurement across Europe. We capture the methodological developments over time and discuss remaining challenges and potential areas for further research. Given the constantly evolving policy environment in Europe, and increasing climate‐change related risks and uncertainties, there is large value to be gained from enhancing our understanding of this fundamental aspect of farmers’ decision‐making processes and consequent actions.
Addiction theory matters—Why there is no dependence on caffeine or antidepressant medication
Authors: Heinz Andreas , Daedelow Laura S. , Wackerhagen Carolin , Di Chiara Gaetano 
Published: March 2019

AbstractWith the development of the ICD‐11, the debate about classifying certain psychoactive substances such as antidepressant medication and caffeine as drugs of dependence is ignited again. We argue that any coherent theory of addiction needs to identify the neurobiological processes elicited by a potentially addictive substance and to clearly define the clinical symptoms associated with these processes, which can then be used to guide diagnosis. Tolerance development and withdrawal symptoms can occur with any pharmacologically active agent, and their presence is not a sufficient criterion for the clinical diagnosis of an addictive disorder. Drug craving, drug seeking, and drug consumption in spite of harmful consequences are further key criteria for the diagnosis of substance dependence. Even though these symptoms have been associated with dopamine release in the ventral striatum, ventral striatal dopamine release alone is not a sufficient criterion of the addictive property of a drug. For example, common reinforcers such as food and sex increase dopamine transmission in the nucleus accumbens, but unlike in addictive substances, their effect is regulated by reward predictability and habituation. We emphasize the importance to integrate neurobiological as well as behavioral and clinical effects of a substance to assess its addictive liability. We provide a number of widely discussed examples and a list of key criteria as a conceptual guideline for addiction research and clinical practice.
