Purpose – The purpose of this paper is to compute and analyze the topological properties of co-authorship network formed between earth scientists in India. As a case study, the authors evaluate bibliographic data of authors who have contributed research articles in the Journal of the Geological Society of India, a premier earth science journal in India. Design/methodology/approach – Research articles totaling 3,903 records from 1970 to 2011 were harvested from the ISI Web of Science SCI database and analyzed using Social Network Analysis. Findings – The author productivity in terms of number of papers published followed Lotka's law with β=2.1027. A dense giant component was detected that spanned 73 percent of the network with a density of 0.0017 and clustering coefficient of 0.631, suggesting high level of knowledge diffusion and a rapid flow of information and creativity in this network. Local metrics were calculated using degree, betweenness and closeness centralities. A strong correlation was seen between degree and author productivity (number of works) and betweenness centrality and author productivity, suggesting that author's number of connections and controlling “in-between” position in the network may be providing the authors’ with the knowledge and resources to be more productive. Originality/value – The impact of human actions on the earth systems is a hot topic of research in India. This is one of the first works that investigates co-authorship networks of Indian earth science researchers.

The Relationship

PurposeAs academic social Q&A networking websites become more popular, scholars are increasingly using them to meet their information needs by asking academic questions. However, compared with other types of social media, scholars are less active on these sites, resulting in a lower response quantity for some questions. This paper explores the factors that help explain how to ask questions that generate more responses and examines the impact of different disciplines on response quantity.Design/methodology/approachThe study examines 1,968 questions in five disciplines on the academic social Q&A platform ResearchGate Q&A and explores how the linguistic characteristics of these questions affect the number of responses. It uses a range of methods to statistically analyze the relationship between these linguistic characteristics and the number of responses, and conducts comparisons between disciplines.FindingsThe findings indicate that some linguistic characteristics, such as sadness, positive emotion and second-person pronouns, have a positive effect on response quantity; conversely, a high level of function words and first-person pronouns has a negative effect. However, the impacts of these linguistic characteristics vary across disciplines.Originality/valueThis study provides support for academic social Q&A platforms to assist scholars in asking richer questions that are likely to generate more answers across disciplines, thereby promoting improved academic communication among scholars.

Purpose This study aims to examine humans’ reactions to service robots’ display of warmth in robot-to-robot interactions – a setting in which humans’ impressions of a service robot will not only be based on what this robot does in relation to humans, but also on what it does to other robots. Design/methodology/approach Service robot display of warmth was manipulated in an experimental setting in such a way that a service robot A expressed low versus high levels of warmth in relation to another service robot B. Findings The results indicate that a high level of warmth expressed by robot A vis-à-vis robot B boosted humans’ overall evaluations of A, and that this influence was mediated by the perceived humanness and the perceived happiness of A. Originality/value Numerous studies have examined humans’ reactions when they interact with a service robot or other synthetic agents that provide service. Future service encounters, however, will comprise also multi-robot systems, which means that there will be many opportunities for humans to be exposed to robot-to-robot interactions. Yet, this setting has hitherto rarely been examined in the service literature.

Purpose The purpose of this paper is to examine whether advertising type (static or dynamic) and appeal (emotional or rational) moderate the relationship between web banner advertising frequency and consumer attitudinal response. Design/methodology/approach A laboratory experiment involving 400 participants was conducted to test for the moderating effect. Factorial ANOVA is used to measure brand attitude. Findings The results identified that the web banner advertisement type acted as a moderator between frequency and brand attitude. However, the moderating effect of banner advertisement appeal was found to be insignificant at a single banner advertisement frequency (i.e. exposure) but significantly different at a higher frequency. The study findings provide better directives for online marketers. Practical implications The major limitation is the fact that the impact of banner advertisement frequency was manipulated from one to five exposures. Future research needs to determine what happens after the fifth exposure, perhaps ten exposures or more, to determine the wear-out effect and in turn, to decide on the optimal frequency level in an effort to design more appropriate web communication strategies. Social implications The result shows that pop-up banner advertisements are intrusive, and that high level of exposures to pop-up banner advertisement could annoy online users. Thus, online advertisers should avoid repeating the pop-up banner advertisements because this could adversely affect the attitude towards the online advertising in general, and could also negatively influence attitudes towards the brand and ultimately effect online purchase. Originality/value This study contributes to the theory by providing more insights into the repetition effect, and comprehensive conclusions can be drawn based on the manipulation of banner advertisement frequency on different frequency levels. The research identifies that if the communication objective is to generate brand attitude, different strategies can be adopted depending on the banner advertisement type (pop-up vs static) and banner advertisement appeal (emotional vs rational).

Purpose This study aims to use a narrative-based simulation approach to explore potential implications of including or excluding a dayroom in the design of an internal medicine ward. Design/methodology/approach The approach involved: collecting data in facilities using field observations and experts’ interviews; modeling representative behavior patterns in the form of rule-based narratives that direct collaborative behaviors of virtual occupants; simulating the behavior patterns in two alternative design options, one of which includes a dayroom; and analyzing the simulation results with respect to selected key performance indicators of day-to-day operations and spatial occupancy, including occupant density in corridors, number and locations of staff-visitor interactions and duration of a doctors’ round procedure. Findings Simulation results suggest that the presence of a dayroom reduces visitors’ density in corridors and diminishes the number of staff–visitor interactions that can delay the performing of scheduled medical procedures. Research limitations/implications A high level of uncertainty is intrinsic to the simulation of future human behavior. Additional work is required to systematically collect large volumes of occupancy data in existing facilities, model additional narratives and develop validation protocols to assess the degree of uncertainty of the proposed model. Originality/value A limited number of studies explore how simulation can be used to study the impact of building design on operations. This study uses a narrative-based approach to address some of the limitations of existing methods, including discrete-event simulations. Preliminary results suggest that the lack of appropriate spaces for patients and visitors to socialize may cause potential disruptions to hospital operations.

Purpose The purpose of this paper is to examine whether investors’ sentiment affects accruals anomaly across European countries. Design/methodology/approach The authors estimate the model using Fama–MacBeth regressions. The sample includes 54,572 firm-year observations for 4,787 European firms during the period 1994–2014. Findings The authors find that investors’ sentiment influences accruals mispricing across European countries. The effect is pronounced for stocks whose valuations are highly subjective and difficult to arbitrage. The cross-country analysis provides evidence that sentiment influences accruals anomaly in countries with weaker outside shareholder rights, lower legal enforcement, lower equity market development, higher allowance of accrual accounting and in countries where herd-like behavior and overreaction behavior are strong. Research limitations/implications The findings suggest the generalizability of the sentiment-accruals anomaly relation in European countries characterized by different cultural values, levels of economic development and legal tradition. Practical implications The findings suggest to caution individuals investors. These investors would be wise to take into account the impact of sentiment on the performance of their portfolio. They must keep in mind that periods of high optimism are accompanied by a high level of accruals and followed by low future stock returns. Originality/value The research supplements previous American studies by showing the significance of the level of sentiment in understanding the accruals anomaly in Europe. Hence, it is important for future studies to consider investor sentiment as an important time-series determinant of the accruals anomaly, particularly for stocks that are hard to value and difficult to arbitrage.

PurposeThe authors examine the impact of corporate investment efficiency on corporate voluntary disclosure for a sample of UK non-financial companies.Design/methodology/approachThe authors use a sample of FTSE All-Share firms for the period of 2007–2014. Disclosure scores are collected from Corporate Financial Information Environment (CFIE). They follow Biddle et al. (2009) and Chen et al. (2011) in measuring corporate investment efficiency.FindingsThe authors find that high level of performance-related disclosure is associated with high level of corporate investment efficiency, while high level of good news information is associated with low level of corporate investment efficiency. They also find evidence on a bidirectional relation between disclosure and corporate investment efficiency.Research limitations/implicationsThe authors’ findings would be of importance to stakeholders and corporations. Stakeholders' investment decisions could be facilitated by understanding the disclosures provided by their firms and how these firms' performance is presented. Corporations become aware of the language which must be used to signal their performance.Practical implicationsCorporations become aware of the language which must be used in their disclosures. As firms may reflect their efficient investments but not in the form of good news in order to avoid revealing their competitive advantage to competitors.Originality/valueThis paper adds to disclosure studies by introducing a new variable, corporate investment efficiency, as a determinant of corporate disclosure practice.

ABSTRACTThe echinocandins caspofungin, micafungin, and anidulafungin, inhibitors of cell wall β-1,3-glucan synthesis, were recently elevated to first-line agents for treating infections due to the azole-refractory yeastCandida glabrata. InCandida albicans, echinocandin resistance is strictly associated with mutations in Fks1, a large integral membrane protein and putative β-1,3-glucan synthase, while mutations in both Fks1 and its paralog Fks2 (but not Fks3) have been associated with resistance inC. glabrata. To further explore their function, regulation, and role in resistance,C. glabratafksgenes were disrupted and subjected to mutational analysis, and their differential regulation was explored. Anfks1Δfks2Δ double disruptant was not able to be generated; otherwise, all three single and remaining two double disruptants displayed normal growth and echinocandin susceptibility, indicating Fks1-Fks2 redundancy. Selection on echinocandin-containing medium for resistant mutants was dependent on strain background: onlyfks1Δ andfks1Δfks3Δ strains consistently yielded mutants exhibiting high-level resistance, all with Fks2 hot spot 1 mutations. Thus, Fks1-Fks2 redundancy attenuates the rate of resistance; further analysis showed that it also attenuates the impact of resistance-conferring mutations. Growth of thefks1Δ and, especially,fks1Δfks3Δ strains was specifically susceptible to the calcineurin inhibitor FK506. Relatedly, FK506 addition or calcineurin geneCMP2disruption specifically reversed Fks2-mediated resistance of laboratory mutants and clinical isolates. RNA analysis suggests that transcriptional control is not the sole mechanism by which calcineurin modulates Fks2 activity.

Purpose – The aim of the present study is to analyze the literature growth, author productivity, authorship pattern, average length of articles and country collaboration of cancer research in India. The Indian Journal of Cancer, which shows the progress of ontological sciences in India, was established in 1963. Indian Journal of Cancer is the first and only periodical serving the needs of all the specialties of oncology in India. The journal is the official publication of the Indian Cancer Society and Indian Society of Oncology. Design/methodology/approach – Thirty-nine issues of the Indian Journal of Cancer, published between 2003 and 2012, have been considered for the study. The collected data were recorded in an Excel spreadsheet and analyzed to find the degree of collaboration (DC) between authors, collaboration between countries and authorship pattern. Since the journal publishes research articles, review articles, editorials, letters to the editor, symposiums, forewords, case reports and special articles, only the 244 research articles published during 2003-2012 have been taken into consideration in this study. Findings – The study revealed that multi-authored papers were more common and that the average length of articles was 5-6 pages. Twenty-two countries contributed papers to this journal during the study period. Additional research is needed to assess the impact of diverse dietary habits, religious practices and lifestyles on the prevention of cancer. Originality/value – More than 50 per cent of the world’s cancer burden, in terms of both numbers of cases and deaths, occurs in developing countries and is rising. By 2020, it is estimated that 70 per cent of all cancer cases will be in these lower-income countries, and approximately one-fifth of these will be in India, with its (still increasing) population of over a billion. While research is necessary to inform effective programs, it is also time to move beyond research to act by implementing programs in cancer prevention and treatment. Cancer is disturbing the growing economy of the country, which can be saved by proper handling of this disease.

Purpose The purpose of this paper is to analyze the influence that two variables related to human resources (HR) have on employee creativity – namely, knowledge management (KM) and motivation management (MM). Design/methodology/approach The linear regression analyses are based on a sample of 306 employees from 11 Spanish companies belonging to three innovative clusters. In addition, “creativity” is considered an antecedent of technological innovation. Findings KM and intrinsic MM are shown to inform creativity, whereas extrinsic MM has no such effect. Practical implications Although this study is based on cross-sectional data, the findings might induce researchers to investigate the effects of other HR variables, such as the types of relations between employees and their long-term impact on creativity. Management should encourage KM and intrinsic MM across employees, as the results indicate that tacit KM, explicit KM and intrinsic MM encourage a positive attitude toward creativity among employees. Originality/value The main contribution is new empirical evidence on the joint influence of aptitudes (KM) and attitudes (MM) on employee creativity. In addition, the study includes a key measure of employee creativity. The evidence reveals the types of KM and MM that encourage or inhibit creative employee behavior. The results show that once employees have reached a medium-high level of extrinsic MM, creativity will be affected solely by intrinsic MM.

Purpose This research paper aims to identify and measure the contribution of the financial safety act (FSA) regulation in improving the level of financial disclosure of listed Tunisian firms. To answer the problems of the subject, the authors tried to hold accountable several determinants of the level of financial disclosure relating to the particular characteristics of the firm, and the adoption of the recommendations envisaged by the FSA, as likely to have an impact on the level of financial disclosure of Tunisian firms. Design/methodology/approach With a sample composed by 20 companies during the period from 2003 to 2010 (160 observations), the contribution of the FSA regulation in improving the level of financial disclosure of listed Tunisian firms was identified and measured. After that, the levels of financial disclosure before and after the FSA were compared. Findings The study results confirm the positive and significant effect of the FSA on the level of financial disclosure. This impact seems to appear through the improvement of the disclosure level during the years which follow the adoption of the new regulation. The results of this study also show that firms with a high level of financial disclosure are those which have an independent board of directors, auditor BIG and joint audit. Originality/value This paper is devoted to evaluate the impact of the FSA n°2005-96 and corporate governance on the level of financial disclosure. The empirical study relates to a sample of 20 firms listed on the Tunis Stock Exchange observed over the period 2003-2010.
