A self organising network model of information gathering by the honey bee swarm
Authors: Foss Richard 
Published: March 2015

Purpose– The purpose of this paper is to investigate how a viable system, the honey bee swarm, gathers meaningful information about potential new nest sites in its problematic environment.Design/methodology/approach– This investigation uses a cybernetic model of a self-organising information network to analyse the findings from the last 60 years published research on swarm behaviour.Findings– Nest site scouts used a modified foraging network to carry out a very thorough survey of the swarm’s problematic environment, providing the swarm with a considerable diversity of potential nest sites for consideration. The swarm utilised a number of randomly recruited groups of scouts to obtain numerous independent opinions about potential nest sites, each privately evaluated, publicly reported and repeatedly tested by new recruits. Independent evaluation of site quality was balanced by interdependent reporting of site location. Noise was reduced by integration over a large number of individual scouts and over a period of time. The swarm was therefore able to reduce potential sources of bias, distortion and noise, providing it with comparatively reliable information for decision making.Originality/value– Information gathering by a honey bee swarm has not previously been modelled as a self-organising information network. The findings may be of value to human decision-making groups.
The effects of nonfinancial performance measures on role clarity, procedural fairness and managerial performance
Authors: Lau Chong M. 
Published: March 2015

Purpose– The purpose of this paper is to ascertain if it is procedural fairness, or role clarity, or both procedural fairness and role clarity that mediate the relationship between non-financial measures and managerial performance. Role clarity and procedural fairness may mediate the relationship between performance measures and managerial performance.Design/methodology/approach– A survey questionnaire was used to collect the required data. The sample was drawn from 149 managers from 103 large manufacturing organisations located in the UK. The data were analysed by structural equation modelling.Findings– The results indicate that it is role clarity that significantly mediates the relationship between non-financial measures and managerial performance. Surprisingly, procedural fairness has no significant mediating effect on the relationship.Originality/value– To date, no prior studies have investigated systematically the effects of non-financial measures as well as the mechanism by which non-financial measures influence role clarity, procedural fairness and managerial performance. This study contributes by incorporating both procedural fairness and role clarity within an integrated model. This assists the research to ascertain precisely which variable (procedural fairness or role clarity) mediates the relationship between non-financial measures and managerial performance as well as the relative strengths of the two mediating variables.
Sustainability reporting integrated into management control systems
Authors: Kerr Jennifer , Rouse Paul , de Villiers Charl 
Published: March 2015

Purpose– This paper aims to examine how three different organisations integrate sustainability reporting into management control systems (MCS).Design/methodology/approach– A case study examination of sustainability reporting integrated into MCS in three New Zealand organisations.Findings– The integration of sustainability reporting into MCS holds advantages for organisations to operationalise sustainability objectives, broaden stakeholder accountability as well as intensify interactions with stakeholders, formalise organisation beliefs and improve communication of sustainability measures internally. While frameworks such as the balanced scorecard (BSC) can facilitate implementation of sustainability reporting, some organisations may choose to fully integrate the latter into their management control system.Originality/value– Sustainability reporting is sometimes seen as an external reporting philosophy that can be managed as a separate project. The authors show it can be integrated into MCS, either entirely or through tools such as the BSC. The authors develop a framework that may be useful in future studies to locate our case organisations.
Productivity in academia
Authors: Wamala Robert , Ssembatya Vincent A. 
Published: March 2015

Purpose
– The purpose of this paper is to investigate causal linkages between output and outcome indicators of productivity in academia.

Design/methodology/approach
– The duration of teaching service and the number of graduate students supervised to completion were adopted as output indicators of productivity. Equivalent outcome indicators were the number of (co)authored books (including book chapters and monographs) and journal articles, respectively. In the investigations, a structural equation modeling approach was adopted.

Findings
– The number of students supervised to completion directly impact the number of (co)authored articles (p < 0.05). The duration of teaching service indirectly influences (co)authored articles by directly impacting the number of students supervised to completion (p < 0.05).

Research limitations/implications
– The causal linkages between the indicators of productivity are an indication of the level of research activity of academia. However, the study does not provide an exhaustive assessment of all indicators of productivity in academia.

Originality/value
– Unlike literature on the subject area that is focused on factors influencing productivity in academia, this study demonstrates casual relationships between the indicators of productivity.
Student involvement in the Egyptian quality assurance system
Authors: Elassy Noha 
Published: March 2015

Purpose
– The purpose of this paper is to study the extent and the quality of student involvement in the quality assurance process (QAP) in Egyptian higher education institutions (HEIs).

Design/methodology/approach
– In this study, two qualitative methods were used to explore the extent and the quality of student involvement; these were focus groups and interviews. The aim of the study was achieved by collecting data from samples of students and staff members belonging to 14 public and private universities and institutes in Egypt.

Findings
– The results indicated that students were not efficiently involved in the QAP at the Egyptian HEIs. They were involved in responding to QA-related questionnaires to a large extent in the case when the HEI was on its way to be accredited or if it was accredited already. It revealed that students were not widely involved in committees regarding QAP. They were invited to meet the external review panel members that were sent by the national accreditation body, but they did not participate in writing the self-evaluation report or even reviewing it. Three factors influencing the extent of student involvement are highlighted.

Originality/value
– The paper provides an empirical insight of the extent and the quality of student involvement in Egyptian HEIs. The importance of this study comes from the fact that after the Egypt’s uprising in January 25, 2011; community pressures appeared to precede positive changes, specifically in the educational sector. From that point of time, higher education (HE) students wanted to be seen as partners in developing their HEIs. Therefore, this study introduces a set of recommendations to increase student involvement to three main Egyptian institutions; these are the ministry of HE, the national quality assurance body and the HEIs.
Mechanical properties of interfacial phases between Sn-3.5 Ag solder and Ni-18 at. % W barrier film by nanoindentation
Authors: Chew C.S. , Durairaj R. , Haseeb A. S. M. A. , Beake B. 
Published: March 2015

Purpose
– The purpose of this paper is to investigate the hardness and elastic modulus on interfacial phases formed between Sn-3.5Ag solder and Ni-18 at. % W alloy film by nanoindentation. It has been found that a ternary amorphous Sn-Ni-W layer formed below Ni3Sn4 IMC at the interface. In this study, mechanical properties of the IMC formed between SA solder and Ni-18 at. % W film after six times reflows were performed by nanoindentation.

Design/methodology/approach
– The characterization was carried at 25°C, and 100 indents were generated. The elastic modulus and hardness were investigated.

Findings
– The results showed that hardness of Ni3Sn4 IMC was higher than amorphous Sn-Ni-W phase. A slight bigger indent was observed on the Sn-Ni-W layer compared with that on the Ni3Sn4 IMC. Lower topographical height in the Sn-Ni-W layer indicated that the Sn-Ni-W phase was softer compared with the Ni3Sn4 IMC. The lower hardness and soft Sn-Ni-W phase is significantly related to the amorphous structure that formed through solid-state amorphization.

Originality/value
– There are no publications about the indentation on the interfacial between the Ni-W layer and the Sn-Ag solder.
Chronic lithium treatment diminishes the female advantage in lifespan in Drosophila melanogaster

Published: March 2015

SummaryTwo studies have concluded that lithium exposure extends the lifespan of Caenorhabditis elegans. However, the effect of lithium on another widely used model organism, Drosophila melanogaster, remains unclear. Here, we demonstrate that chronic treatment with a low to moderate dose of lithium chloride does not extend lifespan in D. melanogaster and that the drug abolishes the female lifespan advantage in flies.

Published: March 2015

SummaryIn the forthcoming decades, it is widely believed that the dominance of colonial and filamentous bloom‐forming cyanobacteria (e.g. Microcystis, Planktothrix, Anabaena and Cylindrospermopsis) will increase in freshwater systems as a combined result of anthropogenic nutrient input into freshwater bodies and climate change. While the physicochemical parameters controlling bloom dynamics are well known, the role of biotic factors remains comparatively poorly studied. Morphology and toxicity often – but not always – limit the availability of cyanobacteria to filter feeding zooplankton (e.g. cladocerans). Filamentous and colonial cyanobacteria are widely regarded as trophic dead‐ends mostly inedible for zooplankton, but substantial evidence shows that some grazers (e.g. copepods) can bypass this size constraint by breaking down filaments, making the bloom biomass available to other zooplankton species. A wide range of algicidal bacteria (mostly from the Alcaligenes, Flavobacterium/Cytophaga group and Pseudomonas) and viruses (Podoviridae, Siphoviridae and Myoviridae) may also contribute to bloom control, via their lytic activity underpinned by a diverse array of mechanisms. Fungal parasitism by the Chytridiomycota remains the least studied. While each of these biotic factors has traditionally been studied in isolation, emerging research consistently point to complex interwoven interactions between biotic and environmental factors.
Bridging the reductive and the synthetic: some reflections on the clinical implications of synchronicity
Authors: Connolly Angela 
Published: March 2015

AbstractWhen Jung introduced the concepts of synchronicity and the psychoid unconscious, he expanded analytical psychology into decidedly uncanny territory. Despite the early interest shown by Freud, anomalous phenomena such as telepathy have become a taboo subject in psychoanalysis. Today, however, there is an increasing interest in thought transference and synchronicity, thus opening the way for a fruitful exchange between different psychoanalytical schools on their clinical implications. I propose to examine some of the ambiguities of Jung's thinking, to clarify how we define synchronicity, the relationship between synchronicities and parapsychological events, and their clinical significance. At the present moment, we are still unsure if such events should be considered as normal and a way of facilitating individuation, or as an indication of psychopathology in the patient or in the analyst, just as we are uncertain about the particular characteristics of the intersubjective field that can lead to synchronicities. Making use of the typology of mind‐matter correlations presented by Atmanspacher and Fach, and the distinction they draw between acategorial and non‐categorial states of mind, I will use two clinical vignettes to illustrate the different states of mind in analyst and analysand that can lead to synchronicities. In particular I will focus on the relationship between analytical reverie and synchronicity.
Virtual reality and the psyche. Some psychoanalytic approaches to media addiction
Authors: Weisel Anja 
Published: March 2015

AbstractThis paper explores the ramifications of excessive use of media on personality development, the development of symbolic and thinking functions and on psychic reality. In doing so, the questions of whether there are specific media objects possessing an intrinsic symbolic quality, and which attachments in the inner world of a child/adolescent can be mobilized or destroyed are discussed.By selecting specific material, computer gamers use their game to activate the field of a personal psychic reality. Hereby, they attempt some kind of self‐healing. However, after leaving the game, conflicts and traumata re‐enacted but unresolved in the game disappear from their temporary representation without generating any resonance in the gamer's psychic experience. Consequently, although states of mind and affects are activated in the computer game, their processing and integration fail; the game results in a compulsive repetition. The construction and consolidation of retrievable maturation and structural development, the representation of the unrepresentable, succeed in the context of the triangulating analytic relationship, initially through a jointly performed symbolic and narrative re‐experience or the recreation of the game.Theoretical considerations are illustrated by means of clinical vignettes.
Lost in (cyber)space: finding two adolescent boys hiding from their own humanity
Authors: Tyminski Robert 
Published: March 2015

AbstractThis article explores the intense psychological effects of compulsive Internet use, which has become increasingly common among adolescent boys and young men. Two cases are presented and discussed to illustrate some of the psychic distortions around thinking and feeling, as these occurred in the analysis of a mid‐adolescent boy and of another patient in later adolescence. A kind of narcissistic omnipotence grounded in magical thinking appeared to take root in their minds, and it led to an avoidant pattern in relationships because of such strong wishes for both distance and control. A short review of the conceptual origins of magical thinking underscores its continued relevance because so many now engage with the Internet. In addition, Anzieu's idea of the ‘skin ego’ is applied to the clinical case material to provide a theoretical framework for the developmental challenges that can appear in adolescent boys who seek to use the Internet as a form of psychic container. Emerging problems that immersion in the Internet might bring into our practices, for example the depleting effects of massive projective identification, are considered and discussed, along with the obvious ways in which using the Internet can be beneficial for connecting with others, for creating new platforms of expression, and for education.

AbstractAn Illumina Infinium SNP genotyping array was constructed for European white oaks. Six individuals of Quercus petraea and Q. robur were considered for SNP discovery using both previously obtained Sanger sequences across 676 gene regions (1371 in vitro SNPs) and Roche 454 technology sequences from 5112 contigs (6542 putative in silico SNPs). The 7913 SNPs were genotyped across the six parental individuals, full‐sib progenies (one within each species and two interspecific crosses between Q. petraea and Q. robur) and three natural populations from south‐western France that included two additional interfertile white oak species (Q. pubescens and Q. pyrenaica). The genotyping success rate in mapping populations was 80.4% overall and 72.4% for polymorphic SNPs. In natural populations, these figures were lower (54.8% and 51.9%, respectively). Illumina genotype clusters with compression (shift of clusters on the normalized x‐axis) were detected in ~25% of the successfully genotyped SNPs and may be due to the presence of paralogues. Compressed clusters were significantly more frequent for SNPs showing a priori incorrect Illumina genotypes, suggesting that they should be considered with caution or discarded. Altogether, these results show a high experimental error rate for the Infinium array (between 15% and 20% of SNPs potentially unreliable and 10% when excluding all compressed clusters), and recommendations are proposed when applying this type of high‐throughput technique. Finally, results on diversity levels and shared polymorphisms across targeted white oaks and more distant species of the Quercus genus are discussed, and perspectives for future comparative studies are proposed.

SummaryIntroductionTo investigate the cardioprotective effect of MicroRNA‐21 (miR‐21) in murine myocardial infarction (MI).MethodsForty C57BL/6 male mice were divided into sham group, MI group, LV‐GFP group, and miR‐21 group. Mice in the MI group, LV‐GFP group, and miR‐21 group were subjected to MI by left anterior descending artery (LAD) ligation, while chest was opened/closed without ligation in sham group. In MI group, expression of miR‐21 in the MI area and its surrounding areas was detected at 1st, 2nd, and 4th week after experiment. Subsequently, lentivirus expressing miR‐21 and lentivirus that did not express miR‐21 were transfected into mice left ventricular cavity of miR‐21 group and LV‐GFP group, respectively. Cardiac function, MI size, miR‐21 expression, collagen I level, fibronectin content, number of α‐SMA‐positive cells, number of apoptotic cells, apoptosis‐related factors were compared between the three groups.ResultsCompared with sham group, miR‐21 levels in MI group were significantly decreased in the 1st week and 2nd week, but were almost the same in the 4th week. Left ventricular fractional shortening (LVFS) and left ventricular ejection fraction (LVEF) in the miR‐21 group improved compared to the LV‐GFP group. In miR‐21 group, myocardial infarct size reduced by 36.9% in comparison with LV‐GFP group. Compared to sham group, miR‐21 expression in the miR‐21 group and LV‐GFP group decreased significantly. In the miR‐21 group, collagen I level, fibronectin content and number of α‐SMA‐positive cells of miR‐21 decreased significantly compared to the LV‐GFP group. The number of apoptotic cells in the MI areas of the miR‐21 group was significantly less than the LV‐GFP group. Compared with the LV‐GFP group, Bcl‐2 level and the ratio of Bcl‐2 to Bax were significantly increased, and the levels of Bax and Caspase‐3 decreased.ConclusionsOur results suggest miR‐21 is an important regulatory molecule in the pathophysiology of MI.

SummarySpatial patterns of community composition turnover (beta diversity) may be mapped through generalised dissimilarity modelling (GDM). While remote sensing data are adequate to describe these patterns, the often high‐dimensional nature of these data poses some analytical challenges, potentially resulting in loss of generality. This may hinder the use of such data for mapping and monitoring beta‐diversity patterns.This study presents Sparse Generalised Dissimilarity Modelling (SGDM), a methodological framework designed to improve the use of high‐dimensional data to predict community turnover withGDM.SGDMconsists of a two‐stage approach, by first transforming the environmental data with a sparse canonical correlation analysis (SCCA), aimed at dealing with high‐dimensional data sets, and secondly fitting the transformed data withGDM. TheSCCApenalisation parameters are chosen according to a grid search procedure in order to optimise the predictive performance of aGDMfit on the resulting components. The proposed method was illustrated on a case study with a clear environmental gradient of shrub encroachment following cropland abandonment, and subsequent turnover in the bird communities. Bird community data, collected on 115 plots located along the described gradient, were used to fit composition dissimilarity as a function of several remote sensing data sets, including a time series of Landsat data as well as simulated EnMAPhyperspectral data.The proposed approach always outperformedGDMmodels when fit on high‐dimensional data sets. Its usage on low‐dimensional data was not consistently advantageous. Models using high‐dimensional data, on the other hand, always outperformed those using low‐dimensional data, such as single‐date multispectral imagery.This approach improved the direct use of high‐dimensional remote sensing data, such as time‐series or hyperspectral imagery, for community dissimilarity modelling, resulting in better performing models. The good performance of models using high‐dimensional data sets further highlights the relevance of dense time series and data coming from new and forthcoming satellite sensors for ecological applications such as mapping species beta diversity.

Published: March 2015

AbstractCardiac myxoma often presents with heterogeneous symptoms and signs and represents a challenging diagnosis. The cutaneous manifestations, if present, are often transient and non‐specific and the clinician must possess a high degree of suspicion to secure the diagnosis. We present the case of a 36‐year‐old woman with a 6‐month history of intermittent, painful, violaceous, non‐blanching macules on the thumb and fingertips of the left hand and right ankle. A cutaneous embolic phenomenon was suspected and an urgent echocardiogram demonstrated an atrial mass, with subsequent histopathology confirming the clinical suspicion of atrial myxoma. Early diagnosis and excision of the tumour avoided serious complications.
