Propulsive design principles in a multi-jet siphonophore
Authors: Sutherland Kelly R. , Colin Sean P. , Costello John H. , Gemmell Brad J. 
Published: November 2018

AbstractCoordination of multiple propulsors can provide performance benefits in swimming organisms. Siphonophores are marine colonial organisms that orchestrate the motion of multiple swimming zooids for effective swimming. However, the kinematics at the level of individual swimming zooids (nectophores) have not been examined in detail. We used high speed, high resolution microvideography and particle image velocimetry (PIV) of the physonect siphonophore,Nanomia bijuga, to study the motion of the nectophores and the associated fluid motion during jetting and refilling. The integration of nectophore and velum kinematics allow for a high-speed (maximum ~1 m s−1), narrow (1-2 mm) jet and rapid refill as well as a 1:1 ratio of jetting to refill time. Overall swimming performance is enhanced by velocity gradients produced in the nectophore during refill, which lead to a high pressure region that produces forward thrust. Generating thrust during both the jet and refill phases augments the distance travelled by 17% over theoretical animals, which generate thrust only during the jet phase. The details of velum kinematics and associated fluid mechanics elucidate how siphonophores effectively navigate three-dimensional space and could be applied to exit flow parameters in multijet underwater vehicles.Summary statement:Colonial siphonophores produce high speed jets and generate forward thrust during refill using a flexible velum to achieve effective propulsion.

AbstractAlkali bees (Nomia melanderi) are solitary relatives of the halictine bees, which have become an important model for the evolution of social behavior, but for which few solitary comparisons exist. These ground-nesting bees defend their developing offspring against pathogens and predators, and thus exhibit some of the key traits that preceded insect sociality. Alkali bees are also efficient native pollinators of alfalfa seed, which is a crop of major economic value in the United States. We sequenced, assembled, and annotated a high-quality draft genome of 299.6 Mbp for this species. Repetitive content makes up more than one-third of this genome, and previously uncharacterized transposable elements are the most abundant type of repetitive DNA. We predicted 10,847 protein coding genes, and identify 479 of these undergoing positive directional selection with the use of population genetic analysis based on low-coverage whole genome sequencing of 19 individuals. We found evidence of recent population bottlenecks, but no significant evidence of population structure. We also identify 45 genes enriched for protein translation and folding, transcriptional regulation, and triglyceride metabolism evolving slower in alkali bees compared to other halictid bees. These resources will be useful for future studies of bee comparative genomics and pollinator health research.

Published: November 2018

AbstractAutism Spectrum Disorder (ASD) is the most prevalent neurodevelopmental disorder in the United States and often co-presents with sleep problems. Sleep problems in ASD predict the severity of ASD core diagnostic symptoms and have a considerable impact on the quality of life of caregivers. Little is known, however, about the underlying molecular mechanisms. We investigated the role of Shank3, a high confidence ASD gene candidate, in sleep architecture and regulation. We show that mice lacking exon 21 of Shank3 have problems falling asleep even when sleepy. Using RNA-seq we show that sleep deprivation increases the differences in gene expression between mutants and wild types, downregulating circadian transcription factors Per3, Dec2, Hlf, Tef, and Reverbα. Shank3 mutants also have trouble regulating wheel-running activity in constant darkness. Overall our study shows that Shank3 is an important modulator of sleep and clock gene expression.
Accurate loop calling for 3D genomic data with cLoops

Published: November 2018

AbstractSequencing-based 3D genome mapping technologies can identify loops formed by interactions between regulatory elements hundreds of kilobases apart. Existing loop-calling tools are mostly restricted to a single data type, with accuracy dependent on a pre-defined resolution contact matrix or called peaks, and can have prohibitive hardware costs. Here we introduce cLoops (‘see loops’) to address these limitations. cLoops is based on the clustering algorithm cDBSCAN that directly analyzes the paired-end tags (PETs) to find candidate loops and uses a permuted local background to estimate statistical significance. These two data-type-independent processes enable loops to be reliably identified for both sharp and broad peak data, including but not limited to ChIA-PET, Hi-C, HiChIP and Trac-looping data. Loops identified by cLoops showed much less distance-dependent bias and higher enrichment relative to local regions than existing tools. Altogether, cLoops improves accuracy of detecting of 3D-genomic loops from sequencing data, is versatile, flexible, efficient, and has modest hardware requirements, and is freely available at: https://github.com/YaqiangCao/cLoops.
An examination of product development approaches within demand driven chains
Authors: Naghi Ganji Elmira , Shah Satya , Coutroubis Alec 
Published: November 2018

PurposeInnovation has been considered as the most important factor in today’s global and competitive environments for meeting growth, customer demands and expectations for any product development environment. The purpose of this paper is to examine the concepts of sustainable development, its practices and impacts within demand-driven supply chain (DDSC) environments. This paper is part of a wider project and within later stages of the study, a novel framework will be developed in order to link new product development (NPD) and demand chain management (DCM) aspects from the analysis of the research findings.Design/methodology/approachThis research has adopted the approach of descriptive method which tends to examine demand chain concept and its evolution through recent years, while having a particular focus into NPD projects.FindingsThe paper investigates early study models through key findings of the literature that focuses on demand chain and NPD for the use and implementation of sustainability measures within manufacturing environments. The research study highlights the need for incorporation of NPD–DCM through the entire business ecosystem entities and also through the flow of information, materials and resources within the structure of the SC. The study finds out the key hurdles of the companies towards adoption of DDSCs in NPD environments, such as lack of cross-organisational association and lack of innovative demand chain frameworks.Originality/valueThe novelty of the research is to develop an early understanding within DDSCs, considering the product development programmes particularly focused on marketing activities. The study provides future researchers with the platform to undertake studies within similar function of DDSC environments.
Lean-Agile FM-BIM: a demonstrated approach
Authors: McArthur J. J. , Bortoluzzi Brandon 
Published: November 2018

PurposeThis paper aims to respond to the high cost of facility management-enabled building information model (FM-BIM) creation and maintenance, a significant and under-researched barrier to adoption for existing buildings. The resultant approach focuses on only value-adding content (“Lean”) developed flexibly and iteratively in collaboration with end-users (“Agile”).Design/methodology/approachFive case studies were developed for university and hospital buildings in collaboration with end-users, guided by the process presented. These informed the refinement of a robust and flexible approach to increase BIM functionality with minimal geometry, focusing instead on the development of specific parameters to map semantic information necessary for each desired FM use.FindingsThe resulting BIM provided a breadth of model functionality with minimal modeling effort: 15 hours average implementation time per supported FM use. This low level of effort was achieved by limiting geometry to where it is necessary for the FM use implementation. Instead, the model incorporated the majority of geometry by reference and focused on semantic and topological parameters to house FM information.Research limitations/implicationsThis study provides the basis for a new ontology structure focused on defining the rules for hosting asset management data (host entity, parameter type and characteristics) to reduce the reliance on complex geometric model development.Practical implicationsBy prioritizing highly beneficial applications, early investment is minimized, providing quick returns at low risk, demonstrating the value of FM-BIM to end-users.Originality/valueThe Lean-Agile approach addresses the known research gap of low-effort, flexible approaches to FM-BIM model creation and maintenance and its effectiveness is analyzed through five case studies.
Talking to the mentees: exploring mentee dispositions prior to the mentoring relationship
Authors: Taylor Z.W. , Black Victoria G. 
Published: November 2018

PurposeThe purpose of this paper is to explore how postsecondary mentoring programs address mentee dispositions prior to the mentee entering the reciprocal relationship, particularly which mentee dispositions are valued across mentoring program types, including peer, community-to-student, faculty-to-student and faculty-to-faculty programs.Design/methodology/approachThis study employed quantitative content analysis to examine 280 institutional US postsecondary mentoring websites across four different institution types (public, four-year; private, four-year, non-profit; private, four-year, for-profit; public, two-year) and four different mentoring program types (peer or student-to-student, community-to-student, faculty-to-student and faculty-to-faculty programs). Grounded coding strategies were employed to generate these four mentoring program types, supported by extant research (Crispet al., 2017).FindingsOf 280 mentoring programs, 18.6 percent articulated mentee dispositions prior to entering the reciprocal relationship. When mentoring programs did address mentees, most programs articulated mentor duties aligned with mentee expectations (47.5 percent of programs) and program outcomes for mentees (65.7 percent of programs) rather than what the mentee can and should bring into a reciprocal relationship.Research limitations/implicationsThis study is delimited by its sample size and its focus on institutional website content. Future studies should explore how mentoring programs recruit and retain mentees, as well as how website communications address the predispositions and fit of mentees within different types of mentoring programs.Practical implicationsThis study provided evidence that many postsecondary mentoring programs in the USA may not be articulating programmatic expectations of mentees prior to the mentoring relationship. By failing to address mentee predispositions, mentoring programs may not be accurately assessing their mentor’s compatibility with their mentees, potentially leading to unproductive mentoring relationships.Originality/valueThis study affirms extant research (Black and Taylor, 2017) while connecting mentor- and coaching-focused literature to the discussion of a mentee dispositions scale or measurement akin to Crisp’s (2009) College Student Mentoring Scale and Searby’s (2014) mentoring mindset framework. This study also forwards an exploratory model of mentoring program inputs and outputs, envisioning both mentor and mentee characteristics as fundamental inputs for a mentoring program rather than traditional models that view mentors as inputs and mentee achievements as outputs (Crisp, 2009; Searby, 2014).

Authors: Kasravi Mahmood , Mahmoudi Amin , Feylizadeh Mohammad Reza 
Published: November 2018

PurposeConstruction projects managers try their best for the project to go according to the plans. They always attempt to complete the projects on time and consistent with the predetermined budgets. Amid so many problems in project planning, the most critical and well-known problem is the Resource-Constrained Project Scheduling Problem (RCPSP). The purpose of this paper is to solve RCPSP using hybrid algorithm ICA/PSO.Design/methodology/approachDue to the existence of various forms for scheduling the problem and also the diversity of constraints and objective functions, myriad of research studies have been conducted in this realm of study. Since most of these problems are NP-hard ones, heuristic and meta-heuristic methods are used for solving these problems. In this research, a novel hybrid method which is composed of meta-heuristic methods of particle swarm optimization (PSO) and imperialist competitive algorithm (ICA) has been used to solve RCPSP. Finally, a railway project has been examined for RCPS Problem in a real-world situation.FindingsAccording to the results of the case study, ICA/PSO algorithm has better results than ICAs and PSO individually.Practical implicationsICA/PSO algorithm could be used for solving problems in a multi-mode situation of activities or considering more constraints on the resources, such as the existence of non-renewable resources and renewable. Based on the case study in construction project, ICA/PSO algorithm has a better solution than PSO and ICA.Originality/valueIn this study, by combining PSO and ICA algorithms and creating a new hybrid algorithm, better solutions have been achieved in RCPSP. In order to validate the method, standard problems available in PSPLib library were used.
The strategic human resource management approaches and organisational performance
Authors: Iqbal Adnan 
Published: November 2018

PurposeDespite the strategic importance of the approaches, most of the approaches consider “internal fit” or “external fit”, and do not consider the role of creative climate. The purpose of this paper is to explore the relationship between approaches to strategic human resource management (SHRM) and organisational performance through a creative climate.Design/methodology/approachThis paper has divided into three parts. First, the paper explores the literatures on the constructs. Second, it examines the relationships between constructs dealt with in the literature. Third, the review identifies the gaps in the literature and describes future recommendations of research for this field.FindingsThis study can serve as a starting point for future research on the relationship between SHRM practices, creative climate and organisational performance in terms of financial, human resource and customer retention. Researchers and practitioners need to understand the relationship between the three constructs.Originality/valueThe paper helps managers need to design strategic HRM policies and practices that are aligned with creative climate and organisational performance. Furthermore, it helps scholars/researchers focus their research on the relationship between HRM approaches (universal and contingency approaches), organisational performance and examining the role of creative climate as a mediator to overcome its causal limitations.
Value relevance of accounting information: an emerging country perspective
Authors: Badu Bismark , Appiah Kingsley Opoku 
Published: November 2018

Purpose
This paper aims to examine the value relevance of accounting information from an emerging country perspective.

Design/methodology/approach
The study adopts Ohlson (1995) Price model to examine the extent to which accounting information explain variation in stock prices of listed firms on the Ghana Stock Exchange.

Findings
The study reveals that earnings and book value of equity exhibit a positive and significant relationship in stock prices. Earnings explain higher variation in stock market values on the Ghana Stock Exchange compared to book value of equity. The study however finds that despite the introduction of the International Financial Reporting Standards in Ghana, the value relevance of book value and earnings have declined significantly over the period 2005-2014.

Research limitations/implications
A key implication is that regulators of capital markets, standards setters and accounting practitioners need to consistently improve upon the quality of financial reporting disclosures which will boost the confidence of users in their reliance on financial statements as the basis for choosing among alternative use of scarce resources. The authors adopted only the price model in testing the hypotheses. However, to provide comprehensive understanding of value relevance of accounting information, future studies can combine both the price and the return models.

Originality/value
The authors extend prior literature in the Ghanaian context with recent data. Finally, the study adds to the efficient market hypothesis by showing how share prices reflect accounting information produced by Ghanaian firms.
Impact of intellectual capital on financial performance: evidence from the Bangladeshi textile sector
Authors: Chowdhury Leena Afroz Mostofa , Rana Tarek , Akter Mahmuda , Hoque Mahfuzul 
Published: November 2018

PurposeThe purpose of this paper is to investigate the influence of intellectual capital (IC) on financial performance and, in turn, to provide insights into its impact on emerging economies.Design/methodology/approachData were collected from 34 textile firms in Bangladesh between 2013 and 2017. The IC efficiency, through value-added intellectual coefficient (VAIC) model, and its impact on financial performance, through return on assets (ROA), return on equity and asset turnover (ATO), was examined using descriptive statistics and multiple regression techniques. The analysis is based on secondary data obtained from annual reports.FindingsThe results indicate the impact of VAIC components on financial performance and also demonstrate diverse relationships with changes in financial indicators. The VAIC components significantly influenced productivity outcomes, with tangible capital playing a major role in both productivity and profitability. Moreover, it was found that structural capital had a considerable effect on ATO and ROA with human capital indicating an insignificant impact on all financial performance indicators.Research limitations/implicationsThe research outcome is specific to the textile industry in emerging economies. The study may guide future research on IC performance in textile firms and cross-industry comparisons.Practical implicationsManagers, firm owners and regulators need to align IC to performance management to sustain the competitive advantage in globalised competitive settings.Originality/valueThe study provides an empirical evidence and extends knowledge of IC utilisation for enhancing the financial performance of the textile firms in emerging economies.

Published: November 2018

Purpose
The purpose of this paper is to understand in a qualitative context, the importance of the EMPRETEC entrepreneurship training in an emerging country context of Brazil. This helps to understand the capacity of entrepreneurship education to improve the ability of individuals to generate new business opportunities.

Design/methodology/approach
The data were collected through three semi-structured interview scripts and analyzed with the support of the NVIVO qualitative analysis software using Bardin content analysis.

Findings
The findings support the assertion that in emerging economies, entrepreneurship education is increasingly important in transforming society through enabling individuals to progress in their careers and life.

Research limitations/implications
It was concluded that the EMPRETEC course fulfilled the objective of encouraging entrepreneurial behavior and stimulating the trainees to contribute to the economic growth of the country. The implication was that participation in entrepreneurship education is strictly interconnected to the success of the trainees.

Practical implications
The study found that there are positive practical outcomes for the trainees’, teachers’ and managers’ perceptions involved in the Entrepreneurship Training Program – EMPRETEC.

Originality/value
The paper helps understand the role of the trainees’ (EMPRETECos), teachers’ and managers’ perceptions of the Program at SEBRAE/Recife about the impact of the Entrepreneurship Training Program – EMPRETEC.
How men interpret women’s luxury brand signals
Authors: Lai Sin Man , Prendergast Gerard 
Published: November 2018

PurposeWomen’s conspicuous display of luxury brands is known to serve the purpose of sending signals to other women, but little is known about how men interpret those signals. The purpose of this paper is to elucidate how men interpret the signals sent by women displaying luxury brands.Design/methodology/approachAn interpretivist approach and phenomenological methods were applied, involving interviews with selected men in Hong Kong.FindingsThe men interviewed suggested that if a woman’s overall image matches that of the brands she displays and the situation, luxurious brands can amplify the woman’s beauty and perceived class status. However, if these factors clash, men react negatively and tend to view the woman as engaging in impression management and pretending to have high social status unjustifiably.Research limitations/implicationsThe sample for this phenomenological study was limited to Hong Kong men only. Culture must, almost by definition, influence men’s views toward women and branded products, so similar exploratory research in other cultures seems justified.Practical implicationsThe findings suggest that marketers should offer “brand education” to help make their female consumers aware of the images their products are trying to establish, and what are the appropriate usage situations. Such consumer education would also reduce the risk of negative image transfer from the brand user to the brands.Originality/valueThe current understanding of female luxury brand signals is limited to female-vs-female intra-sexual competition. By examining how men interpret female luxury brand signals, this research addresses an important research gap.
