Authors: Brand Philipp , Saleh Nicholas , Pan Hailin , Li Cai , Kapheim Karen M. , Ramírez Santiago R. 
Published: April 2017

AbstractBees provide indispensable pollination services to both agricultural crops and wild plant populations, and several species of bees have become important models for the study of learning and memory, plant-insect interactions and social behavior. Orchid bees (Apidae: Euglossini) are especially important to the fields of pollination ecology, evolution, and species conservation. Here we report the nuclear and mitochondrial genome sequences of the orchid beeEuglossa dilemmaBembé & Eltz.Euglossa dilemmawas selected because it is widely distributed, highly abundant, and it was recently naturalized in the southeastern United States. We provide a high-quality assembly of the 3.3 giga-base genome, and an official gene set of 15,904 gene annotations. We find high conservation of gene synteny with the honey bee throughout 80 million years of divergence time. This genomic resource represents the first draft genome of the orchid bee genusEuglossa,and the first draft orchid bee mitochondrial genome, thus representing a valuable resource to the research community.
Cell size sensing in animal cells coordinates anabolic growth rates with cell cycle progression to maintain uniformity of cell size
Authors: Ginzberg Miriam B. , Chang Nancy , Kafri Ran , Kirschner Marc W. 
Published: April 2017

AbstractThe uniformity of cell size in healthy tissues suggests that control mechanisms might coordinate cell growth and division. We derived a method to assay whether growth rates of individual cells depend on cell size, by combining time-lapse microscopy and immunofluorescence to monitor how variance in cell size changes as cells grow. This analysis revealed two periods in the cell cycle when cell size variance decreases in a manner incompatible with unregulated growth, suggesting that cells sense their own size and adjust their growth rate to correct aberrations. Monitoring nuclear growth in live cells confirmed that these decreases in variance reflect a process that selectively inhibits the growth of large cells while accelerating growth of small cells. We also detected cell-size-dependent adjustments of G1 length, which further reduce variability. Combining our assays with chemical and genetic perturbations confirmed that cells employ two strategies, adjusting both cell cycle length and growth rate, to maintain the appropriate size.

Published: April 2017

The SUT-NANOTEC-SLRI beamline was constructed in 2012 as the flagship of the SUT-NANOTEC-SLRI Joint Research Facility for Synchrotron Utilization, co-established by Suranaree University of Technology (SUT), National Nanotechnology Center (NANOTEC) and Synchrotron Light Research Institute (SLRI). It is an intermediate-energy X-ray absorption spectroscopy (XAS) beamline at SLRI. The beamline delivers an unfocused monochromatic X-ray beam of tunable photon energy (1.25–10 keV). The maximum normal incident beam size is 13 mm (width) × 1 mm (height) with a photon flux of 3 × 108to 2 × 1010 photons s−1(100 mA)−1varying across photon energies. Details of the beamline and XAS instrumentation are described. To demonstrate the beamline performance,K-edge XANES spectra of MgO, Al2O3, S8, FeS, FeSO4, Cu, Cu2O and CuO, and EXAFS spectra of Cu and CuO are presented.
Arts and culture management
Authors: Ruiz Jaime , Colbert Francois , Hinna Alessandro 
Published: April 2017

Purpose
The purpose of this paper is to provide an overall picture of the five articles included in this issue highlighting their contributions and revealing the importance of academic research for arts and culture management as a nascent topic in the Latin American context.

Design/methodology/approach
This paper elaborates a critical description of the main aspects of the papers included. The contributions are grouped together around central topics pertaining to arts and culture management such as: audience creation and environment; museums, competition and efficiency; and management skills and entrepreneurship.

Findings
The contributions of the articles are as diverse as the topics included in them. Some highlight the importance of the context in audience creation processes, others reveal the determinants of the institutional variables in the efficiency of artistic organisations, and a final one, reveals the deconstruction of an artistic genre and its contribution to the comprehension of organisations’ innovation processes. However, the most important contribution, within the Latin American context, consists basically in a process of dissemination and knowledge of the research developed in different international contexts and which may apply to the analysis of arts and culture management in the region.

Originality/value
As noted in the body of this paper, the topic of cultural management is novel and has acquired notable importance in developed economies in which the arts and culture sector has strategic value. Latin America reveals an institutional revolution which situates the cultural sector in a predominant position where its contribution to the creation of social and economic value turns it into a key field in Latin American societies. Arts and culture constitute a factor of value creation which requires carefully planned and pertinent management processes. This publication, through its five contributions, all European, is a valuable tool of dissemination for knowledge and management in Latin America, where academic research into the sector is, as yet, incipient.
Understanding competition and service offer in museum marketing
Authors: Komarac Tanja , Ozretic-Dosen Durdana , Skare Vatroslav 
Published: April 2017

Purpose
The purpose of this paper is to explore the current role of competition as one of the neglected aspects of museum marketing management. It also aims to discover whether museum professionals consider museums to be market immune and to find out what they think about the role of competition in creating and managing their existing and new services.

Design/methodology/approach
The theoretical part of the paper is based on a review of the literature from the multidisciplinary field of arts and museum marketing management. The exploratory qualitative research included 17 museum professionals and was carried out in 17 museums in one EU emerging market country.

Findings
Museum professionals are not aware of the competition, or they tend to ignore its existence. They consider the preservation of objects (exhibits) to be equally or even more important than providing services. However, additional services become important. Although some museum professionals try to engage visitors in the active creation of museum experience, most are still conservative in such terms.

Research limitations
The primary research limitations are related to intentional, convenience sample and the perspective of one employee (marketing manager or museums’ director).

Originality/value
Research findings provide valuable insights for both marketing academics and professionals engaged in the museum marketing management field. The contribution of the paper is also contextual as it helps to bridge the gap existing in museum marketing management research in the context of the emerging markets.
Intuition and mood of investors in financial markets
Authors: Braga Robson , Fávero Luiz Paulo Lopes , Takamatsu Renata Turola 
Published: April 2017

Purpose
The purpose of this paper is to evaluate investor behaviour related to the timing of selling financial assets based on an intuitive evaluation of the current market trend and growth expectation.

Design/methodology/approach
The experiment involved 1,052 volunteer participants who made decisions about stock sales in an environment that simulated a home broker platform to negotiate stocks. Zero-inflated regression models were used.

Findings
The results show that investors’ attitudes, or beliefs, determine whether they will buy or keep risky assets in their investment portfolios; they may decide to sell such assets, even though market shows an upward trend. Such results make a new contribution to behavioural finance within the context of prospect theory and the disposition effect.

Originality/value
The originality of this paper lies in the use of new and innovative techniques (zero-inflated Poisson and negative binomial regression models) applied to real data obtained experimentally.
A causal relationship model linking corporate reputation and customer-based brand equity
Authors: Casimiro Almeida Maria Graça , Coelho Arnaldo 
Published: April 2017

PurposeThe purpose of this paper is to understand the precursors of corporate reputation (CR) and their impacts on brand equity (BE), and to analyse the moderating role of corporate social responsibility (CSR) perceptions.Design/methodology/approachThis study proposes a theoretical model which is tested using structural equation modelling. In total, 464 valid questionnaires were collected from a sample of customers of the biggest union of dairy cooperatives of the Iberian Peninsula.FindingsResults show that the better the reputation, the higher the BE; however, these findings are more robust among customers with higher perceptions of CSR.Research limitations/implicationsThis study is based on cross-sectional data from a single company.Practical implicationsThe results may help managers build a better reputation and therefore increase their BE. CSR practices are essential to reinforcing this relationship.Social implicationsThis paper contributes to the competitiveness of a type of organisation which is closely associated to the social structure of the rural population.Originality/valueThe results may help cooperatives’ managers to increase CR and BE. The emphasis is on the need to adopt CSR practices.
Going back to the roots of entrepreneurship
Authors: Bizjak Davide , Calcagno Monica , Sicca Luigi Maria 
Published: April 2017

PurposeThe purpose of this paper is to investigate the specific field of arts entrepreneurship by focussing on the practices of vertical dance; a language of contemporary dance where dancers act on a vertical axis, moving suspended on the surface of buildings and walls. The authors’ focus on vertical dance as a meaningful corporal practice to explore the particular combination of dance and human movement, going beyond its purely metaphoric dimension.Design/methodology/approachThe authors’ adopt a micro-social perspective, observing the practices (Gherardi, 2012; Nicolini, 2012; Sicca, 2000), that took place from 2013 to 2015 in the daily work of Wanda Moretti, a Venetian choreographer and co-founder of the company “Il posto”, observed in different contexts of artistic practices (Zembylas, 2014).Research limitations/implicationsDeconstructing the overlapping dimensions that compose the space in our daily experience (force of gravity and the supporting surface), vertical dance clarifies how often we undervalue the complexity of the space and, at the same time, opens up the way for a better understanding and investigation of entrepreneurship in artistic fields.Originality/valueThe study sheds light on the way in which different categories, such as the human body, space, and movement, are a particular entanglement of elements, useful in highlighting some of the fundamental assumptions at the heart of the field of entrepreneurship. The heterogeneous complexity of space and bodies is emphasised, challenging its ordinary conceptualisation.
Do family CEOs benefit investment efficiency when they face uncertainty?
Authors: Gao Weiwei , Li Wanli , Huang Zhen 
Published: April 2017

PurposeThis paper aims to investigate whether family CEOs benefit investment efficiency under uncertainty with Chinese family firms and to test the moderating effect of ownership structure, including family ownership, the separation of family control from family ownership and the multiple large shareholder structure.Design/methodology/approachFixed-effects models are designed for a sample of 5,734 firm-year observations for Chinese family firms from 2009 to 2014.FindingsThe results show that investment efficiency is low under uncertainty, and having family CEOs can reduce this negative relationship. Further analysis reveals that for firms with family CEOs, the negative effect of uncertainty on investment efficiency is weaker when the family has higher ownership, when family control is less separated from family ownership, or when family firms have multiple large shareholder structures.Research limitations/implicationsThe authors do not distinguish founder-CEOs and descendant-CEOs. Most of Chinese family firms are still managed by founders, so the authors cannot explore the generation effect although different generations manage firms differently. Because family succession is becoming a more and more important problem in China, further research may be able to explore the generation effect.Practical/implicationsThis paper suggests that in emerging economies with weak investor protection, outside minority shareholders can avoid expropriation from family owners by investing in firms with large family ownership, little separation of family control from ownership or multiple large shareholder structure. In addition, policymakers can encourage institutional investors to participate in family business to improve corporate governance.Originality/valueDrawing on both Type I and Type II agency theory perspectives, the authors argue that although family CEOs can generally benefit firms’ investment efficiency, the benefits vary with firms’ ownership structure. In other words, family CEOs are not absolute agents or stewards but some extent of combination of both.
Does R&D create additional business value through IT?
Authors: Wang Yu , Wang Tie-nan , Li Xin 
Published: April 2017

PurposeR&D indicates absorptive capacity, which may affect IT payoff. The purpose of this paper is to examine how R&D investment affects the relation between IT investment and firm performance and under what circumstances R&D intensity is more beneficial to IT returns. Such study has been lacking in R&D research and IT payoff literature.Design/methodology/approachA conceptual model for linking IT investment, R&D investment, environmental dynamism and firm performance was developed and tested by data collected from Chinese listed firms from 2007 to 2013, using fixed effects regression model.FindingsThe results show positive moderating effects of firm R&D investment and government R&D subsidies on the relation between IT investment and firm performance. Furthermore, the impact of firm R&D investment on IT payoff is stronger for firms in more dynamic environments. The findings suggest that R&D investment creates additional business value through interactions with IT, and complementarities between R&D and IT, as manifested in their interaction effect on firm performance vary across industry sectors.Research limitations/implicationsThis paper indicates the importance of complementarities between R&D and IT, which should prove helpful to researchers and practitioners engaged in Chinese business.Originality/valueThis paper presents one of the first attempts at examining the moderating effect of R&D investment on the relation between IT investment and firm performance. Especially this study helps to understand under what circumstances R&D investment is more or less likely to be beneficial to IT returns.
The impact of director’s heterogeneity on IPO underpricing
Authors: Xu Zhi-Jian , Wang Li , Long Jing 
Published: April 2017

PurposeThe purpose of this paper is to investigate whether the Boardroom heterogeneity affects IPO underpricing for entrepreneurial firms, where Boardroom heterogeneity was classified in terms of functional background, educational background, age and length of tenure.Design/methodology/approachA national research design was conducted using data collected from 355 firms listed on China’s Growth Enterprise Market from its start in 2009 to 2012.FindingsThe author found that IPO underpricing has a significant negative correlation with functional heterogeneity, a positive correlation with educational heterogeneity, a significant negative correlation with age heterogeneity, but it does not show significant correlation with heterogeneity in tenure. Board heterogeneity affects IPO underpricing of entrepreneurial firms partially, which means functional, educational and age heterogeneity conveys signals to potential investors regarding a firm’s quality.Research/limitations/implicationsMore entrepreneurial firms in more years for data and long-term performance research design in future research would be required for further understanding of the relationships among the variables in this study.Practical/implicationsThis paper suggests that IPO firms may make use of such an influencing mechanism to determine the issue price or to control the IPO underpricing by showing the Boardroom heterogeneity.Originality/valueThis paper revealed the influence of the characteristics of board members of such firms on IPO underpricing, which is rare in recent studies comparing to the study for the top management team; also this study provides empirical support for such effect.
How emergent strategy influences institution: a qualitative study of a private firm in China
Authors: Zhao Jing , Wang Ming , Zhu LiMin 
Published: April 2017

PurposeInstitutional work mainly focused on the purposive action of rational actors. However, the evolution of institution is not only affected by deliberate actions but also by emergent strategic patterns. Through a qualitative study of emergent aggression strategy in a Chinese leading private firm, Gome, this paper aims to explore the role of emergent strategy in institutional work. The paper finds that emergent strategy influences the normative and cognitive institution unconsciously and offers actors specialized identities. The present analysis also suggests that the emergent strategy-based institution needs a supporting and repairing system for maintenance.Design/methodology/approachThis study primarily considers the micro aspect of emergent strategy and institutional work. It calls for detailed observation, interviews and archival materials which can make up a comprehensive in-depth picture. The authors remain skeptical to what people claim and try to get multiple sources of information. Also, the topic the authors deal with is relatively under-researched, and it is valuable to get explorative richness. Therefore, an interpretive qualitative approach is adopted to investigate actual events from “the native’s” perspective.FindingsWe found that an emergent strategy, which is realized but without previous plans, can also construct a “proto-type institution”, only in an unconscious way. The precondition is that the strategic resources of the focal firm are abundant enough for it to set the criteria of inter-organizational sanctions and rewards. In addition, the authors believe that supportive system and repairing system underpin the maintenance of established institutions.Originality/valueFirst, by combining the research on emergent strategy to institutional work, the authors extend the scope of the latter by adding unconscious institutional work. Even if the agent-based view is adopted, rational actors can still influence the institution. Second, the authors explored the institutional outcome of emergent strategy, which fills the paucity of strategy process research. Third, aggression, the specific emergent strategy in this paper, can be turned into “plans for the future”. Its prevalence in the emerging market will attract more academic attention.
Testing extremely small samples using the flash diffusivity method
Authors: McMasters Robert , Harth Zachary J. , Taylor Ryan P. , Brooke George M. 
Published: April 2017

Purpose
The purpose of the present research is to examine very small-sized samples of approximately 2-mm diameters. For samples of this size, the holder must make contact with the entire perimeter surface of the sample, and the sample is held in place by friction. This necessitates a mathematical model for the direct solution which accommodates the holder and a contact resistance between the holder and the sample.

Design/methodology/approach
Most flash diffusivity testing is performed on samples which are nominally 12-13 mm in diameter and are held by only a small contact area around the perimeter of the sample in a holder. With an experiment set up in this way, the effects of conduction between the sample and the holder are normally ignored.

Findings
This research examines the effects of the holder and the contact resistance on the measured thermal diffusivity of the sample and includes experimental results from laboratory measurements.

Originality/value
This work provides a method for finding thermal diffusivity for extremely small samples. This capability is important in cases involving precious materials or highly toxic materials where only small samples are available.
Multicriteria identification of parameters in microscale heat transfer
Authors: Kus Waclaw , Dziatkiewicz Jolanta 
Published: April 2017

Purpose
The purpose of this paper is to present the multicriteria identification method used for solving the microscale heat transfer problem. The thin film exposed to ultrashort laser pulse is modeled using the finite difference method. The parameters of the model are tuned on the basis of experimental data. The multicriteria identification of the numerical model parameters is performed for subsets of experimental data.

Design/methodology/approach
The multicriteria identification method is used in the paper. The Pareto front for two criterions is created. The two-temperature model of heat transfer in microscale is used in the numerical model.

Findings
The multicriteria identification for two subsets of experimental data leads to different results. The obtained Pareto front allows to choose the most suitable set of numerical model parameters.

Originality/value
The multicriteria identification method was used for the first time to solve the microscale heat transfer problem.
Estimation of the non-linear diffusion coefficient with Marcov Chain Monte Carlo method based on the integral information
Authors: Bulinski Zbigniew , Orlande Helcio R.B. 
Published: April 2017

Purpose
This paper aims to present development and application of the Bayesian inverse approach for retrieving parameters of non-linear diffusion coefficient based on the integral information.

Design/methodology/approach
The Bayes formula was used to construct posterior distribution of the unknown parameters of non-linear diffusion coefficient. The resulting aposteriori distribution of sought parameters was integrated using Markov Chain Monte Carlo method to obtain expected values of estimated diffusivity parameters as well as their confidence intervals. Unsteady non-linear diffusion equation was discretised with the Global Radial Basis Function Collocation method and solved in time using Crank–Nicholson technique.

Findings
A number of manufactured analytical solutions of the non-linear diffusion problem was used to verify accuracy of the developed inverse approach. Reasonably good agreement, even for highly correlated parameters, was obtained. Therefore, the technique was used to compute concentration dependent diffusion coefficient of water in paper.

Originality/value
An original inverse technique, which couples efficiently meshless solution of the diffusion problem with the Bayesian inverse methodology, is presented in the paper. This methodology was extensively verified and applied to the real-life problem.
