Does the London Stock Exchange require an upstairs market? Evidence from block trades
Authors: Gregoriou Andros 
Published: August 2016

Purpose
– The purpose of this paper is to test if the empirical relationship between the size of trades and market liquidity can be pooled across different block sizes on the London Stock Exchange (LSE).

Design/methodology/approach
– The authors use pooling and non-pooling econometric tests in a panel framework.

Findings
– When the authors differentiate between various block sizes, the authors find that for trades in excess of 50,000 shares, there is a positive association between the size of the trade and the bid-ask spread, due to a lack of liquidity in the financial market. The results provide strong evidence that an upstairs market may be required in order to provide liquidity for large block trades on the LSE.

Originality/value
– This is the first study to directly test if the LSE requires an upstairs market to provide liquidity for large trade transactions.
An explanation of spread’s ability to predict economic activity
Authors: Evgenidis Anastasios , Siriopoulos Costas 
Published: August 2016

Purpose– For over two decades numerous studies have provided evidence on the predictive ability of the yield spread for real economic growth. While all this large literature has focussed on how well the spread helps predict real activity, none of these has given an answer on why the spread predicts. The purpose of this paper is to deal with this issue by trying to find an answer on the reason and the economic conditions under which the spread proves to be so powerful predictor of economic activity.Design/methodology/approach– The authors examine whether the explanation of spread’s predictive ability lies behind interest rate volatility supposing that the economy oscillates between high- and low-volatility regimes. For this reason the authors nest GARCH models into Markov regime switching models.Findings– When the authors assume that the economy simply oscillates between different regimes, interest rate volatility does not explain the spread’s predictive ability. However, the authors obtain a very interesting result when the authors augment the conditional variance with a level effects term. This ensures that in an environment with high levels of interest rates – in which the rational agents expect the economy to slow down – there is a greater possibility for the economy to switch to a high-volatility regime. Under these economic conditions, interest rate volatility appears to be the reason of spread’s predictive power from one up to three years.Originality/value– This study contributes to the relevant literature by providing an explanation on the reason and the economic conditions under which the spread proves to be so powerful predictor of economic activity.

Authors: Barile Sergio , Lusch Robert , Reynoso Javier , Saviano Marialuisa , Spohrer James 
Published: August 2016

Purpose– The purpose of this paper is to create awareness on the need for lifting up the level of analysis in service research by focusing on systems, networks, and ecosystems to contribute to the research expansion of the traditionally narrow view of service.Design/methodology/approach– This conceptual paper is built upon three blocks. First, the viable systems approach is revised to highlight the survival, viability, and complexity of service systems. Second, the dynamics of service networks is discussed using an ecological view of service with a nested, networked configuration. Third, these two previous perspectives are integrated using the fundamentals of ecosystems thinking.Findings– This paper outlines a novel, tri-level approach reorienting and reframing our thinking around systems, networks, and ecosystems. Some research challenges and directions that could expand the body of knowledge in service research are also discussed.Research limitations/implications– The tri-level approach proposed in this conceptual paper could be enriched with other theoretical perspectives and empirical explorations.Practical implications– Lifting the level of analysis by focussing on service systems, service networks, and service ecosystems would allow practitioners to expand their business perspective to better face the challenges of complex business settings, enabling them to co-create value for all their stakeholders.Originality/value– The paper contributes to set the foundation for the next stage of service research by going beyond dyadic interactions to address dynamic systems, networks, and ecosystems across different interaction patterns in complex business configurations.
Project management factors affecting the enterprise resource planning projects’ performance in Jordan
Authors: Abu-Hussein Ruba , Hyassat Mohammed , Sweis Rateb , Alawneh Afnan , Al-Debei Mutaz 
Published: August 2016

Purpose
This purpose of this research is to investigate the project management factors that are affecting the enterprise resource planning (ERP) projects’ performance in Jordan. Based on the conducted literature review, four project management areas were selected for this research: the communication management, the human resource management, the time management and the risk management.

Design/methodology/approach
In total, 24 Jordanian ERP projects were surveyed through designing a questionnaire that was distributed to project managers. Moreover, interviews were conducted with both the project manager of the largest ERP project in Jordan and a consultant of one of the Big 5 consulting firms.

Findings
The interviews’ results confirmed the effect of the four project management areas on the ERP project performance which is consistent with the questionnaire results except for the risk management.

Originality/value
No similar studies were found in Jordan. Moreover, this subject was tackled by only a few studies, so more research is recommended to investigate the project management factors that are affecting the ERP projects’ performance. It is also recommended that future studies extend this research on factors other than project management factors.
Recovery is no laughing matter – or is it?
Authors: Barker Alex Byron , Winship Gary 
Published: August 2016

Purpose
– The purpose of this paper is to describe an exploratory pilot study to assess the methods used to evaluate an innovative programme of comedy workshops for a small cohort of people recovering from substance misuse problems. The comedy workshops involved participants working with a professional comedian to explore, develop, write and finally perform a stand-up comedy routine drawing from their own personal experiences.

Design/methodology/approach
– The impact of the programme was gauged using questionnaires; the Warwick-Edinburgh Mental Well-being Scale, the Rosenberg Self-Esteem Scale, the General Self-Efficacy, Scale and the Life Orientation Test-Revised and Eco-Mapping Tool.

Findings
– Ten participants began the programme with four participants following through to public performance at an evening showcase event. The quantitative measures showed favourable results on three positive outcome measures; psychological well-being, self-esteem and self-efficacy. Participant’s number of social relationships and strength of relationships decreased following the intervention, however, relationships were more mutual and were characterized by less conflict following the workshop.

Research limitations/implications
– The small sample limits generalization of this study, but the methods for data collection were found to be feasible. Preliminary findings suggest that the workshops have a positive impact on recovery.

Originality/value
– This paper describes an evaluation of an innovative programme of comedy workshops for people recovering from substance abuse problems. The preliminary findings point to a new hypothesis about recovery, that successful recovery might be characterized by a smaller social network, with stronger mutual bonds.
The perspectives of people who use mental health services engaging with arts and cultural activities
Authors: Jensen Anita , Stickley Theodore , Edgley Alison 
Published: August 2016

Purpose
– The purpose of this paper is to present a study of arts engagement for mental health service users in Denmark.

Design/methodology/approach
– The study was completed at Hans Knudsen Instituttet, Denmark. It involved analysis of emerging themes from semi-structured interviews with six participants who had participated in a structured visit to the National Gallery (Statens Museum for Kunst) in Denmark.

Findings
– Multiple benefits for people who use mental health services engaging in arts activities are reported. Arts activities are described as a central component of everyday life; a way of life and a significant factor in getting through the day. Barriers are identified in the interdisciplinary working between the museum educator and participants.

Social implications
– This study identifies that the participants benefited from taking part in the arts/cultural activity. Findings also suggest that if museums are offering activities to people who use mental health services they should equip staff with training designed to support appropriate ways of working with this group. This interdisciplinary activity offers a relatively untapped potential arena of support.

Originality/value
– The paper will be of relevance and value to those working with mental health and arts. The study demonstrates the importance for mental health service users to engage in creative activity and for museum staff to have appropriate skills for inclusion to be successful.
A day in the life of a peer support worker: re-entry
Authors: Watson Emma 
Published: August 2016

Purpose
– The purpose of this paper is to share the experiences and reflections of a peer support worker over the course of a day working in mental health services.

Design/methodology/approach
– A narrative approach has been taken to structure reflections based on the experience of returning to work after taking sick leave.

Findings
– Reflections are offered based on the process of returning to work and the way that this experience sheds light on personal recovery.

Originality/value
– This paper adds to the small number of accounts of the experiences of peer support working in mental health services and as such is highly original.
Learning from faculty voices on information literacy
Authors: Bury Sophie 
Published: August 2016

Purpose
This paper aims to investigate faculty conceptions of information literacy (IL) in a digital information landscape by examining faculty definitions of IL in the context of undergraduate education, as well as faculty perceptions of, and expectations for, undergraduate IL knowledge and abilities.

Design/methodology/approach
This is a qualitative research study with 24 semi-structured interviews of faculty in different disciplines at a large public research university in Toronto, Ontario.

Findings
Faculty view IL as fundamentally intertwined with other academic literacies and as central for the successful pursuit of much undergraduate academic research work including developing autonomous, engaged learners. Faculty place special emphasis on fostering higher-order cognitive skills, especially developing a questioning disposition and the ability to evaluate, contextualize and synthesize information sources. Faculty see considerable scope for improvement of undergraduate IL capabilities, and a large majority see a role for themselves and librarians here.

Practical implications
Findings of this and other studies align well with core elements in the new IL guidelines and frameworks for higher education both in North America and the United Kingdom. This includes highlighting a need for a strong faculty role in shaping IL in higher education in the future, a need for a holistic lens in developing multiple academic literacies, an emphasis on high-order cognitive abilities and a recognition of the importance of affective dimensions of learning IL.

Originality/value
This paper fills a gap in the literature where there is an absence of studies, especially of a qualitative nature, which explore faculty conceptions of IL. A majority of studies published focus instead on librarian conceptions and practice.

Design/methodology/approach
This paper outlines the use of the instructional design process to effectively develop specialized Guide on the Side (GotS) tutorials for upper-level business students.

Findings
Students valued the interactive nature of the GotS tutorials and appreciated that the instruction was at point of need.

Research limitations/implications
This paper describes one librarian’s journey of creating interactive tutorials with the instructional design process. It is a starting point for other academic librarians looking to embed tutorials in courses.

Originality/value
GotS is an interactive tutorial software and librarians are looking for effective ways to incorporate online tutorials into their information literacy instruction.
Physiological regulation and efficient xylem water transport regulate diurnal water and carbon balances of tropical lianas

Published: August 2016

Summary

Tropical lianas deploy most of their leaves towards the top of the forest canopy, whereas trees exhibit a more stratified crown. Forest canopies are often exposed to hot and windy conditions, and how lianas cope with the extremely high transpirational demands under these environments remains unknown.

We investigated stem hydraulic properties, leaf drought tolerance, diurnal changes in leaf and stem water potentials (Ψleaf and Ψstem), stomatal conductance (gs), photosynthetic rate, sap flow and stem native percentage loss of conductivity (PLC) for four liana species in a tropical forest in southwest China. Five co‐occurring tree species were also selected for comparison.

Lianas reached maximal transpiration at a relatively lower vapour pressure deficit (<1 kPa) than did co‐occurring trees, suggesting vigorous photosynthesis during the morning. However, liana gs declined markedly over the day, with low gs at midday and afternoon. Lianas generally had higher stem sapwood‐specific conductivity and maximum sap flux density but were less tolerant to drought‐induced cavitation than were evergreen trees. Both lianas and trees lost leaf turgor in the top canopy at midday, but lianas lost leaf turgor earlier (∼2 h) than trees.

Seven of eight species exhibited midday increases in PLC when xylem tensions were released to −0·3 to −0·5 MPa for PLC measurements. On average, lianas experienced high PLC (35·9%), along with a greater degree of disequilibrium between leaf and stem water potentials than trees (ΔΨstem–leaf: 1·37 MPa vs. 0·75 MPa) during the day. Earlier stomatal closure and efficient water transport may help lianas maintain higher Ψstem than trees despite having similar Ψleaf.

Our results provide evidence that physiological regulation and efficient water transport mediate daily water relations in tropical lianas and may explain how lianas operate efficiently in tropical seasonal forests. Further studies involving a broader range of species are needed to confirm our findings.
Importance of deep water uptake in tropical eucalypt forest

Published: August 2016

Summary

Climate models predict that the frequency, intensity and duration of drought events will increase in tropical regions. Although water withdrawal from deep soil layers is generally considered to be an efficient adaptation to drought, there is little information on the role played by deep roots in tropical forests. Tropical Eucalyptus plantations managed in short rotation cycles are simple forest ecosystems that may provide an insight into the water use by trees in tropical forests.

The contribution made by water withdrawn from deep soil layers to the water required for evapotranspiration was quantified daily from planting to harvesting age for a Eucalyptus grandis stand using a soil water transfer model coupled with an ecophysiological forest model (MAESPA). The model was parameterized using an extensive data set and validated using time series of the soil water content down to a depth of 10 m and water‐table level, as well as evapotranspiration measured using eddy covariance.

Fast root growth after planting provided access to large quantities of water stored in deep soil layers over the first 2 years. Eucalyptus roots reached the water‐table at a depth of 12 m after 2 years. Although the mean water withdrawal from depths of over 10 m amounted to only 5% of canopy transpiration from planting to a harvesting age of 5 years, the proportion of water taken up near the water‐table was much higher during dry periods. The water‐table rose from 18 to 12 m below‐ground over 2 years after the harvest of the previous stand and then fell until harvesting age as evapotranspiration rates exceeded the annual rainfall.

Deep rooting is an efficient strategy to increase the amount of water available for the trees, allowing the uptake of transient gravitational water and possibly giving access to a deep water‐table. Deep soil layers have an important buffer role for large amounts of water stored during the wet season that is taken up by trees during dry periods. Our study confirms that deep rooting could be a major mechanism explaining high transpiration rates throughout the year in many tropical forests.
Analysis ofGambierdiscustranscriptome data supports ancient origins of mixotrophic pathways in dinoflagellates

Published: August 2016

SummaryToxic dinoflagellates pose serious threats to human health and to fisheries. The genusGambierdiscusis significant in this respect because its members produce ciguatoxin that accumulates in predominantly tropical marine food webs and leads to ciguatera fish poisoning. Understanding the biology of toxic dinoflagellates is crucial to developing control strategies. To this end, we generated ade novotranscriptome library fromG. caribaeusand studied its growth under different culture conditions to elucidate pathways of carbon (C) and nitrogen (N) utilization. We also gathered available dinoflagellate transcriptome data to trace the evolutionary history of C and N pathways in this phylum. We find that rather than being specific adaptations to the epiphytic lifestyle inG. caribaeus, the majority of dinoflagellates share a large array of genes that putatively confer mixotrophy and the ability to use N via the ornithine‐urea cycle and nitric oxide synthase production. These results suggest that prior to plastid endosymbiosis, the dinoflagellate ancestor possessed complex pathways that linked metabolism, intercellular signaling, and stress responses to environmental cues that have been maintained by extant photosynthetic species. This metabolic flexibility likely explains the success of dinoflagellates in marine ecosystems and may presage difficulties in controlling the spread of toxic species.

Published: August 2016

AimUniversity and college students in wealthy countries may be vulnerable to financial food insecurity. If food insecure students have suboptimal health, their ability to learn and excel in their education could be compromised. This Canadian study examined the relationship of food security status to diet and self‐perceived health and academic quality among students receiving emergency food hampers from the Campus Food Bank at University of Alberta.MethodsA convenience sample of 58 students completed a survey.ResultsOf participating students, 10.3% were food secure, 44.8% were moderately food insecure and 44.8% were severely food insecure. Overall, 32.8% rated their general health as fair/poor, 27.6% rated their mental health as fair/poor and 60.3% indicated at least one adverse academic outcome of not having enough money for food. Compared to other participating students, students with severe food insecurity had a greater likelihood of fair/poor general health (odds ratios (OR) 4.03, 95% confidence intervals (CI) 1.10–14.78); fair/poor mental health (OR 4.96, 95% CI 1.28–19.19); being unable to concentrate in class or during an exam (73.1% vs 40.6%, χ2 = 6.12, P = 0.013); relying on food hampers (34.6% vs 9.7%, χ2 = 5.57, P = 0.018); and, consuming fewer daily fruits, vegetables and legumes (2.12 vs 2.97 cup equivalents, P = 0.009).ConclusionsFood insecurity compromises students’ health, diet and academic quality. Campus food banks are not the solution to student hunger. Governmental and university‐based programmes and policies are needed to improve the food security situation of university students.
Rhizosphere selection of Pseudomonas putida KT2440 variants with increased fitness associated to changes in gene expression

Published: August 2016

SummaryAs the interface between plant roots and soil, the rhizosphere is a complex environment where nutrients released by the plant promote microbial growth. Increasing evidences indicate that the plant also exerts a selective pressure on microbial populations in the rhizosphere, favouring colonization by certain groups. In this work, we have designed an experimental setup to begin analysing the evolution of a specific bacterial population in the rhizosphere, using Pseudomonas putida KT2440 as model organism. After several rounds of selection without passage through laboratory growth conditions, derivatives of this strain with increased fitness in the rhizosphere were isolated. Detailed analysis of one of these clones indicated that this effect is specific for rhizosphere conditions and derives from changes in its transcriptional profile in this environment, with 43 genes being differentially expressed with respect to the parental strain. Several of these genes belong to functional categories which could affect stress adaptation and availability of particular nutrients. By inactivating two genes identified as upregulated in the selected clone (coding for a stress–response protein and a rRNA modifying protein), these functions were shown to contribute to rhizosphere fitness. Our data also suggest the existence of different evolutionary pathways leading to increased rhizosphere fitness.
