Involving teachers in reducing children’s media risks
Authors: Stiller Anja , Schwendemann Hanna , Bleckmann Paula , Bitzer Eva-Maria , Mößle Thomas 
Published: November 2017

Purpose
The purpose of this paper is twofold: first, to introduce MEDIA PROTECT, a multi-modal intervention for parents and teachers with six components preventing problematic, and in the long run addictive, use of screen media by children; second, to present results of a formative evaluation of the teacher training, an important component of the intervention.

Design/methodology/approach
In presenting the intervention, the authors used a common framework to describe complex interventions systematically. For the evaluation, participants were recruited from German schools and kindergarten for a cluster-controlled trial. As part of a formative evaluation, the participants completed written questionnaires to determine the importance of different components of the intervention in addition to their overall satisfaction. Additional qualitative interviews with teachers were conducted.

Findings
The authors recruited n=50 kindergartens and n=9 schools; n=30 received the intervention. N=222 teachers participated in the training and n=192 completed the questionnaire (86 per cent). Seven qualitative interviews were conducted. Participants exhibited high levels of overall satisfaction with the training, considered it moderately to highly relevant to their work, and exhibited varying satisfaction levels with different components and multipliers. The qualitative data support these findings.

Originality/value
Few interventions to date have pursued a universal approach to the prevention of problematic screen media use. This evaluation of MEDIA PROTECT is the most recent study in Germany, which involves a complex programme through which teachers are taught ways to promote the age-adequate use of screen media in the family, parents are provided with guidance and healthy leisure time activities for children are fostered.
The Ripple Effect at an inter-suburban level in the Sydney Metropolitan area
Authors: Blake Jay Peter , Gharleghi Behrooz 
Published: November 2017

PurposeThe purpose of this study is to investigate the Ripple Effect of house prices at an inter-suburban level of analysis in the Sydney metropolitan area. By doing this, more practical information of price transmission can be provided to improve residential real estate purchasing decisions of market participants. Equity from residential real estate is a major component of household wealth and is frequently used to improve and upgrade homes. With the ever-increasing prices of real estate in Sydney making more efficient purchasing decisions can grow this wealth quicker allowing a household to obtain financial related goals at a quicker pace.Design/methodology/approachUsing a two-stage sampling technique strings of adjoining suburbs from different Sydney regions were analysed using a combination of price graphs, Engle–Granger and Johansen co-integration techniques and Granger causality tests.FindingsPairwise co-integration was lacking throughout the various suburb strings, whereas multivariate co-integration was found in the lower priced areas further from the central business district, as these areas also experience less price volatility. The geographical location of suburbs therefore plays an important role in the ability to predict an individual suburb’s price movements. For a prominent Ripple Effect to exist at this level the best conditions would consist of a singular demand centre with restricted geographical space to which this demand can spread. Causal pathways were subsequently mapped for each suburb string identifying price transmission pathways and confirming support that while the standard Ripple Effect does not exist at an inter-suburban level, it is still possible to predict price movements by considering the price behaviour of surrounding suburbs.Originality/valueThis paper adds to the literature by examining the Ripple Effect across different suburbs in Sydney. This is done via an extensive search through the literature and analysing recent real estate data.

Authors: Ekberg Siri , Gao Shang 
Published: November 2017

PurposeThe purpose of this paper is to investigate the challenges of using ICT in secondary schools in Sweden from teachers’ perspectives.Design/methodology/approachThe research followed a qualitative research approach. First, a conceptual framework was developed based on previous research. Then, four teachers, teaching in six different subjects in secondary schools in Sweden, participated in semi-structured interviews that consisted of open-ended questions exploring their views on the challenges of using ICT in secondary schools.FindingsAccording to the results, the authors found that the biggest challenges were associated with the perspective of teaching and teaching preparation. Most challenges from previous research have been re-confirmed by the interviewees in this study. In addition, some new challenges were identified in this study. For instance, the results indicated that it was time consuming to find plagiarism of students’ exercises, and there was a lack of ICT training of digital resources provided by the schools.Originality/valueThe investigation of using ICT in secondary schools is of scientific significance because it enriches the understanding of strengths and challenges of using ICT in educational activities. In particular, this research aims to shed light on challenges that teachers may face when using ICT in secondary schools. This research can also contribute to making future strategic plans for the use of ICT in secondary schools.
How teachers’ personality affect on their behavioral intention to use tablet PC
Authors: Camadan Fatih , Reisoglu Ilknur , Ursavas Ömer Faruk , Mcilroy David 
Published: November 2017

Purpose
The purpose of this paper is to explore the effects of personality traits on teachers’ technology acceptance.

Design/methodology/approach
To this end, a demographic information survey, Five-Factor inventory, and technology acceptance measure were used for data collection. The data were analyzed via structural equation modeling.

Findings
According to the findings, conscientiousness has no significant effect on behavioral intention (BI) whereas openness and extraversion have positive indirect effects. On the other hand, agreeableness and neuroticism have negative indirect effects on BI. It was seen that the developed model explains 70 percent of BI, 77 percent of attitude toward use, 42 percent of perceived usefulness, 64 percent of perceived ease of use, and 15 percent of computer self-efficacy (CSE). It was revealed that CSE mediates the indirect effects of different personality traits on these variables.

Practical implications
In this regard, highlighting the conveniences to be brought by using Tablet PCs and equipping teachers with competencies to use relevant technologies during teacher training and in-service training may be effective in developing BI to use Tablet PCs among teachers.

Originality/value
The present study is different from previous studies in that it examines more than one technology through more than one measurement, takes personality as the predictor of technology use tendencies, and focuses on causal relationships between technology use and personality.
MOOCs: a differentiation by pedagogy, content and assessment
Authors: Mohamed Misrah Hamisah , Hammond Michael 
Published: November 2017

PurposeMassive open online courses (MOOCs) have often been divided between connectivist MOOCs and extended MOOCs (xMOOCs). Each form of MOOC proposes a distinctive view about knowledge acquisition. However, the breakdown between the two MOOCs is too broad in practice, and a more fine-grained approach is needed. Thus, the purpose of this paper is to describe the organisational features of exemplar MOOCs and their differences.Design/methodology/approachThe study observed the ten newly available MOOCs aimed at teachers of English as a second language and included examples from existing providers: NovoEd, Coursera, FutureLearn and Canvas. These MOOCs were analysed and compared using a matrix with three main focuses: pedagogical assumptions, content materials and assessment.FindingsThe findings revealed that all courses corresponded to the idea of an xMOOC in that they were run on a model of instructional design. However, the course materials varied in respect to media used, use of networking, discussion forums and degree of openness. In terms of assessment, all MOOCs used formative approaches, all had automated responses but only some had summative and peer assessment.Originality/valueThe study succeeded in showing the variation in courses, thus enabling the range of possibilities open to course designers and providers.
Impact of investment efficiency on cost of equity: evidence from China
Authors: Majeed Muhammad Ansar , Zhang Xianzhi , Umar Muhammad 
Published: November 2017

Purpose
The purpose of this study is to investigate the effect of investment efficiency on cost of equity capital.

Design/methodology/approach
Prior research indicated that any governance mechanism which reduces the agency conflict reduces the cost of equity capital. This study provides empirical evidence that investment efficiency represents such governance mechanism which reduces agency conflict and hence cost of equity. The authors use price earning growth ratio (Easton, 2004) and Ohlson and Juettner-Nauroth (2005) model for the measurement of cost of equity while investment efficiency measure of Biddle et al. (2009) have been employed to examine the association. We also use Chen et al. (2013) measure of investment efficiency for robustness.

Findings
The results show that investment efficiency is negatively associated with cost of equity. It was also found that there is a strong relationship of investment efficiency with cost of equity for non-state-owned enterprises (NSOEs), while no significant relationship is found for state-owned enterprises. Furthermore, overinvestment is significantly associated with cost of equity capital. However, no significant relationship was found between underinvestment and cost of equity.

Originality/value
The results provide empirical support to the argument that investment efficiency acts as a mechanism which represents lower agency conflict. Moreover, the findings provide evidence that government act as “deep pocket” while NSOEs are punished by investors for inefficient resource allocation. This study also proposes that there is a positive relationship between overinvestment and cost of equity.
Anti-money laundering disclosures and banks’ performance
Authors: Nobanee Haitham , Ellili Nejla 
Published: November 2017

Purpose
The purpose of this paper is to explore the extent of anti-Money laundering (AML) disclosures in the annual reports and websites by differentiating between UAE Islamic and conventional banks, and examine the effect of AML disclosure on UAE bank’s performance.

Design/methodology/approach
This study uses content analysis to explore the extent of AML disclosure in the annual reports and the dynamic panel data two-step robust system to study the impact of the AML disclosures on banking performance.

Findings
The findings show that AML disclosure is at a low level for all UAE banks, conventional and Islamic banks. The results also show that the degree of AML disclosure on the websites of the banks is higher than that in the annual reports.

Research limitations/implications
The sample for this study comes only from banks traded on UAE markets. Thus, the results may not be generalizable to banks traded on other financial markets.

Practical implications
Because of the cross-border character of the money laundry practices, our study suggests the UAE central bank to internationalize the AML regulations and develop an international AML regime as efforts to respond to the international development of the money laundry practices.

Originality/value
This is the first study that develops an index to measure the AML disclosure and contributes significantly in providing greater insight in respect to AML disclosure in banking industry within the emerging markets.
Liability for negligently issued anti-mafia certificates
Authors: Monaco Paola 
Published: November 2017

Purpose
This paper aims to analyse the different forms of liability that might apply under Italian private law to anti-mafia advisors who negligently perform their duties, with particular regards to auditors concerning the drafting of mandatory anti-mafia certificates as bidding documents for public procurement contracts.

Design/methodology/approach
The analysis is based on the comparative law methodology of dissociation of “legal formants”, that is, on the study of separate contributions by each element of the legal system – from black-letter provisions to judicial dicta, from scholars’ arguments to administrative practices – to the making of legal rules in a given setting.

Findings
Neither case law nor academic writing is abundant on this topic. Yet, it can be fairly assumed that an advisor who negligently drafts anti-mafia certificates might incur both contractual and tortious liability.

Originality/value
The paper investigates an area, which has so far been largely unexplored, and, thus, contributes to paving the way for a better understanding of the legal framework applicable to the cases under examination.
Strategies for using ResearchGate to improve institutional research outcomes
Authors: Ali Muhammad Yousuf , Wolski Malcolm , Richardson Joanna 
Published: November 2017

Purpose
The purpose of this paper is to investigate how to help improve a higher education institution’s research profile by using existing resources and existing research outputs.

Design/methodology/approach
This study was based on quantitative data extracted manually from QS University Rankings-Asia 2016, the 2015 Ranking of Pakistani higher education institutions (HEI) and ResearchGate (RG). Resultant data were loaded into Excel and analyzed in SPSS version 21.

Findings
The results of this study indicate that, while there is no direct correlation between an institution’s national/international ranking and its respective RG score, there is a tendency for lower-ranked institutions to have a lower RG score.

Research limitations/implications
This study was limited to data extracted from RG; however, it would be useful to apply the same methodology to other relevant academic scholarly network sites (ASNS).

Practical implications
This paper has suggested strategies which may be of relevance to those institutions in other countries which are aspiring to lift their national ranking through improved research profiles. Libraries are important contributors to the support of institutional research goals.

Originality/value
There have been no previous published research studies on either the potential for ASNS to contribute to enhancing research outcomes for Pakistani HEI or the role that libraries could play in supporting these outcomes.
Shared leadership in teams
Authors: Han Soo Jeoung , Lee Yunsoo , Beyerlein Michael , Kolb Judith 
Published: November 2017

PurposeThis paper aims to examine the effect of shared leadership on student project team processes and outcomes. The authors focused on shared leadership and its association with team processes (coordination, goal commitment and knowledge sharing) and team performance.Design/methodology/approachTo examine the shared leadership, team processes and performance model, the authors conducted two separate surveys of 158 graduate and undergraduate students working in project teams at a large southwestern university.FindingsResults showed that shared leadership positively affected coordination activities, goal commitment and knowledge sharing, which in turn positively affect team performance. Each team process factor had a mediation effect, although shared leadership had no direct effect on team performance.Research limitations/implicationsThis research adds to the knowledge of important team process factors through which shared leadership indirectly affects team performance.Practical implicationsBased on the findings, the authors provided implications for students and instructors that shared leadership can facilitate team performance by enabling team members to coordinate activities, commit to goals and share knowledge effectively.Originality/valueThis study presents an initial understanding of the shared leadership-team performance relationship by introducing influential variables, such as coordination activities, goal commitment and knowledge sharing in a team.
MTS coordination in practice: micro-level insights to increase MTS performance
Authors: Wijnmaalen Julia , Voordijk Hans , Rietjens Bas 
Published: November 2017

Purpose
This paper aims to generate insight into the processes that lie at the heart of multiteam system (MTS) coordination and how MTS coordination develops. The four propositions developed can set a future MTS research agenda and enable MTS leaders to increase MTS performance.

Design/methodology/approach
A military and civilian construction MTS has been studied over several months. The longitudinal character, micro-level focus and abductive research approach respond to the call for more in-depth, empirical studies of MTS processes.

Findings
Based on the research findings, four propositions are advanced: the interrelatedness of trust, communication and shared mental models is at the heart of MTS coordination; MTSs are sensitive to a downward spiral triggered by the negative relationship between MTS coordination and the occurrence of negative events; a salient component team identity accelerates this downward spiral; and effective MTS leadership is a perquisite for successful MTS coordination. The findings also indicate that because the MTS research field is still maturing, there is value in testing the degree to which existing knowledge on teams is generalizable to an MTS context.

Practical implications
The research generates three practical suggestions for MTS leaders to increase MTS performance: usual ways of structuring or leading a team might elicit intergroup behavior in MTSs, a conventional “fun” teambuilding program is not effective in an MTS situation and balance formal and informal coordination.

Originality/value
The abductive and empirical character of this study is unique in the field of MTS research. Moreover, the four propositions on MTS coordination advance current knowledge on MTS processes. Additionally, the study generates new insights that could enable MTS leaders to increase MTS performance.
Nutrient deficiencies and the restriction of compensatory mechanisms in copepods
Authors: Burian Alfred , Grosse Julia , Winder Monika , Boschker Henricus T. S. 
Published: November 2017

Abstract

The flexible regulation of feeding behaviour and nutrient metabolism is a prerequisite for consumers to grow and survive under variable food conditions. Thus, it is essential to understand the ecological trade‐offs that restrict regulatory mechanisms in consumers to evaluate the consequences of nutrient limitations for trophic interactions.

Here, we assessed behavioural and physiological adjustments to nutrient deficiencies in copepods and examined whether energy limitation, food digestibility or co‐limitation with a second nutrient restricted compensatory mechanisms.

A combination of 13C‐labelling and compound‐specific stable isotope measurements revealed that copepods compensated nitrogen deficiencies by raising retention efficiencies of amino acids (AA). The costs of higher retention efficiencies were reflected in the doubling of structural fatty acids (FA), probably required for morphological adaptations of the gut. A depletion of highly unsaturated FA in storage lipids and their selective retention suggested that these FA became co‐limiting and restricted a further increase in AA retention efficiencies.

Copepods feeding on phosphorus‐limited algae showed a marked increase in ingestion rates but were not fully able to compensate dietary deficiencies. The increase in ingestion rates was thereby not restricted by higher foraging costs because energy storage in copepods increased. Instead, thicker cell walls of nutrient‐limited algae indicated that algal digestion resistance restricted the extent of surplus feeding.

The strongly nutrient‐specific response of copepods had large implications for recycling rates, growth efficiencies and the potential top‐down control at the plant–animal interface. Compensatory mechanisms to mitigate nutrient deficiencies are therefore an essential aspect of trophic interactions and have the potential to alter the structure of food web.

Published: November 2017

Abstract

Despite playing central roles in nutrient cycles and plant growth, soil microbes are generally neglected in the study of ecosystem services (ES), due to difficulties to assess their diversity and functioning. However, to overcome these hurdles, new conceptual approaches and modern tools now provide a means to assess the role of micro‐organisms in the evaluation of ES.

In managed grasslands, soil microbes are central in providing nitrogen (N)‐related ES such as maintenance of soil fertility and retention of mineral forms of N. Here, we applied state‐of‐the‐art techniques in microbial ecology and plant functional ecology to uncover the intrinsic link between N‐related bacterial functional groups, important plant functional traits, environmental factors and three proxies of maintenance of soil fertility and potential for N‐leaching across managed grasslands in three regions of Europe.

By constructing well‐defined structural equation modelling, we showed that including key microbial traits improve on average more than >50% of the total variances of ES proxies, that is, ammonium () or nitrate () leaching, and soil organic matter content. Geographic differences arose when considering the direct relationships of these ES proxies with specific microbial traits: nitrate leaching was positively correlated to the maximum rate of nitrification, except in the Austrian site and potentially leached –N was negatively correlated to the fungi/bacteria ratio, with the exception of the French site.

Synthesis and applications. The integration of soil microbial functional traits in the assessment of nitrogen‐related grassland ecosystem services has direct contributions for understanding sustainable management of grassland ecosystems. The fundamental aspects of this study suggest that integrating a soil microbial component in grassland management may enhance sustainability of such grass‐based agroecosystems.
