Authors: Khobzi Hamid , Teimourpour Babak 
Published: October 2014

Purpose– The purpose of this study is to assign polarity score to each post from Facebook fan pages, and then examine whether the Comments submitted by users on a post from fan page have a significant relationship with the popularity of that post. Being aware of how to enhance the popularity of posts will help companies in terms of administrating their fan pages.Design/methodology/approach– In the context of fan page and post popularity, the authors test significance of the relationship between Comments’ polarity and number of Likes and Comments of a post in different Facebook pages by regression method. The data are collected from different fan page posts in Facebook, and a sentiment analysis approach is proposed to accomplish this research.Findings– Results show that the relation between users’ Comments and popularity of fan page posts is strongly significant. Outcomes of this research are useful for every company in terms of monitoring and managing their brand fan pages on social networking sites such as Facebook.Originality/value– Investigation of factors influencing popularity of fan page posts in social media is almost a new area of study that dates back to recent years. The authors use a sentiment analysis approach to evaluate a new concept describing the relationship between users’ Comments and popularity of posts from Facebook fan pages. Moreover, a part of dataset is extracted from Facebook by a crawler which is an advantage to prior studies.
ERP system implementation announcements: does the market cheer or jeer the adopters and vendors?
Authors: Ajit D. , Donker Han , Patnaik Sapan 
Published: October 2014

Purpose
– The purpose of the study is to examine the implementation of Enterprise Resource Planning (ERP) on the announcement of firms’ stock market returns. The authors investigate the stock market reaction on ERP adopters and ERP vendor firms in the USA during 1990-2010. The study examines firm- and non-firm-specific factors including the role of the financial analyst in explaining the determinants of the cumulative abnormal returns surrounding ERP announcements of adopting firms.

Design/methodology/approach
– Data on ERP system implementation announcements of 112 US firms for the period 1990-2010 were collected from LexisNexis Academics. The authors estimate abnormal returns using an event study methodology for each of the ERP announcements based on the Fama–French three-factor and Fama–French-momentum four-factor models for ERP adopters and for vendors. Subsequently, the authors explain the determinants of abnormal returns in terms of firm and non-firm behavioral variables using cross-section regression methodology.

Findings
– The empirical results establish that cumulative abnormal returns of US firms on ERP system implementation announcements are positive, signifying that investors view this decision positively and that ERP implementation contributes to enhanced business value in the future. On the contrary, the impact of ERP announcements on vendors is muted. We find that the extent of financial analyst coverage negatively impacts abnormal returns, while the extent of stock market liquidity has a significant positive impact on abnormal returns.

Research limitations/implications
– This study is based on a sample of ERP implementing firms which are predominantly large firms and on technology provided by one vendor that is predominantly monopolistic.

Practical implications
– Firms’ attitudes toward implementing an ERP system for future efficiency gains and the implications on the stock market (and indirectly, on the cost of equity of adopters) provide valuable insights for firms and stock markets.

Originality/value
– This study brings clarity to the debate on stock market impacts of ERP implementation announcements – stock markets cheer such announcements. The study also contributes to the literature by examining firm-specific factors (such as performance, size and leverage) and non-firm-specific factors (such as market risk and analyst coverage) in explaining the determinants of abnormal returns of firms announcing ERP investment.
The effect of power and gender on technology acceptance
Authors: Zhang Lu , Nyheim Peter , S. Mattila Anna 
Published: October 2014

Purpose– This paper aims to examine the joint effect of power and gender on individuals’ perceptions and evaluations of information systems (IS), and their behavioral intentions of technology acceptance.Design/methodology/approach– This study uses a 2 (powerful vs powerless) × 2 (female vs male) between-subject experimental design. A total of 128 subjects participated in the experiment.Findings– The results suggest that there is a significant gender difference in terms of technology acceptance in the high-power condition. Further, such a gender difference is attenuated in the low-power condition. Specifically, when primed with the feeling of powerful, male users (vs female users) have higher computer self-efficacy and rate the IS as easier to use and more enjoyable. However, when the feeling of powerless was elicited, the effect of gender on technology acceptance disappeared.Originality/value– The gender effect on technology acceptance has been widely studied. The current research extends the literature by considering the moderating effect of power on such a gender effect.

Authors: Jung SoYeon , (Sunny) Kim Jungsun , Farrish John 
Published: October 2014

Purpose– The purpose of this paper is to provide a benchmark for hotel operators to understand in-room technology trends and the impact of in-room technology on business performance.Design/methodology/approach– The survey questions are based on existing literature and suggestions from the American Hotel and Lodging Association Technology and E-commerce Committee. The authors collected 206 usable samples from managers, vice presidents, presidents, owners and executives from hotel companies and utilized cross-tab analysis and multiple regression analysis.Findings– The results demonstrate that installing specific in-room technologies can have a significant effect on enhancing the customer experience and increasing revenue. The study also presents the most commonly installed in-room technologies those hoteliers plan to install in the near future.Research limitations/implications– Proper strategies are recommended to help hospitality managers understand the impact of different in-room technologies on the hospitality industry; particularly as they relate to guest experience and profitability.Originality/value– By identifying the most popular in-room technologies currently available and examining which in-room technologies can be effective at enhancing guest experience and increasing revenue, this study fills the gap between the findings of previous studies and the observations from industry practitioners.
Culture, politics and university library consortia in China and the US
Authors: Perushek D. E. , Douglas Anne 
Published: October 2014

Purpose– Using three university library consortia China Academic Library and Information System (CALIS) (China), Greater Western Library Alliance (GWLA) (USA) and Joint University Librarians Advisory Committee (JULAC) (Hong Kong) as examples, the purpose of this paper is to compare the administration of three university consortia and to explore the cultural, educational and geopolitical forces that produce and shape university library consortia.Design/methodology/approach– The methodology used reviewed published and proprietary documents, interviews and observation.Findings– While the stated objectives are similar, the three vary markedly in size, funding source, and whether programming is a bottom-up decision or emanates from the central government. CALIS was started by China ' s Ministry of Education, who also helps in setting programmatic agendas and appointing managers; GWLA came into existence through the efforts of a small group of university librarians, elect their own board and set programming in response to member needs and suggestions; JULAC, initiated by the university librarians in Hong Kong has some support from the government through bodies charged with the oversight of the universities. The differing educational systems also influence programming, for example in the relative importance member libraries place on preferential inter-library loan.Originality/value– There are few comparative studies of library consortia found in Asia and the US comparative studies of consortia encourage an understanding of the benefits of different consortia models.
Improving academic library website accessibility for people with disabilities
Authors: Billingham Lisa 
Published: October 2014

Purpose
– The purpose of this paper is to explain how Edith Cowan University (ECU) Library improved the accessibility of their web site, aiming for Web Content Accessibility Guidelines (WCAG) version 2.0 Level AA. It describes the results obtained.

Design/methodology/approach
– Initial testing by consultants was conducted in October 2012. The web site was defined as all webpages which appear part of the library web site, including supplier webpages, plus pages from the university web site and library web site. Library staff applied the recommendations to pages which they could edit, and discussed the recommendations with suppliers to improve their product
'
s accessibility. The web site was re-tested in June 2013.

Findings
– ECU Library web site failed WCAG 2.0 Level A standard in the initial testing and re-testing. Many individual pages which failed initially passed the re-test. The smallest improvement was seen in suppliers’ web sites.

Practical implications
– This paper could help libraries to improve web site accessibility, as it covers negotiating with suppliers to upgrade their web sites, plus upgrading editable webpages. It shows initial and re-test results, allowing libraries to compare their results to those of ECU. Legislation and guidelines state web sites should be accessible to all users and organisations providing non-accessible web sites risk being sued.

Social implications
– A web site not complying with WCAG version 2.0 would be very difficult for people with disabilities to access. Upgrading ECU Library
'
s web site will provide all users with more equal access to the resources.

Originality/value
– This study describes problems in upgrading academic library webpages and related supplier web sites and organisation web site to improve accessibility for people with disabilities.
Optimal control during drilling in GFRP composite laminates
Authors: Pal Singh Amrinder , Sharma Manu , Singh Inderdeep 
Published: October 2014

Purpose– Damage due to delamination is an important issue during drilling in polymer-matrix composites (PMCs). It depends on thrust force and torque which are functions of feed rate. Transfer function of thrust force with feed rate and torque with feed rate is constructed through experiments. These transfer functions are then combined in state-space to formulate a sixth-order model. Then thrust force and torque are controlled by using optimal controller. The paper aims to discuss these issues.Design/methodology/approach– A glass fiber reinforced plastic composite is drilled at constant feed rate during experimentation. The corresponding time response of thrust force and torque is recorded. Third-order transfer functions of thrust force with feed rate and torque with feed rate are identified using system identification toolbox of Matlab®. These transfer functions are then converted into sixth-order combined state-space model. Optimal controller is then designed to track given reference trajectories of thrust force/torque during drilling in composite laminate.Findings– Optimal control is used to simultaneously control thrust force as well as torque during drilling. There is a critical thrust force during drilling below which no delamination occurs. Therefore, critical thrust force profile is used as reference for delamination free drilling. Present controller precisely tracks the critical thrust force profile. Using critical thrust force as reference, high-speed drilling can be done. The controller is capable of precisely tracking arbitrary thrust force and torque profile simultaneously. Findings suggest that the control mechanism is efficient and can be effective in minimizing drilling induced damage in composite laminates.Originality/value– Simultaneous optimal control of thrust force and torque during drilling in composites is not available in literature. Feed rate corresponding to critical thrust force trajectory which can prevent delamination at fast speed also not available has been presented.
Process modeling, joint-property characterization and construction of joint connectors for mechanical fastening by self-piercing riveting
Authors: Grujicic Mica , Snipes Jennifer , Ramaswami S. , Abu-Farha Fadi 
Published: October 2014

Purpose
– The purpose of this paper is to propose a computational approach in order to help establish the effect of various self-piercing rivet (SPR) process and material parameters on the quality and the mechanical performance of the resulting SPR joints.

Design/methodology/approach
– Toward that end, a sequence of three distinct computational analyses is developed. These analyses include: (a) finite-element modeling and simulations of the SPR process; (b) determination of the mechanical properties of the resulting SPR joints through the use of three-dimensional, continuum finite-element-based numerical simulations of various mechanical tests performed on the SPR joints; and (c) determination, parameterization and validation of the constitutive relations for the simplified SPR connectors, using the results obtained in (b) and the available experimental results. The availability of such connectors is mandatory in large-scale computational analyses of whole-vehicle crash or even in simulations of vehicle component manufacturing, e.g. car-body electro-coat paint-baking process. In such simulations, explicit three-dimensional representation of all SPR joints is associated with a prohibitive computational cost.

Findings
– It is found that the approach developed in the present work can be used, within an engineering optimization procedure, to adjust the SPR process and material parameters (design variables) in order to obtain a desired combination of the SPR-joint mechanical properties (objective function).

Originality/value
– To the authors’ knowledge, the present work is the first public-domain report of the comprehensive modeling and simulations including: self-piercing process; virtual mechanical testing of the SPR joints; and derivation of the constitutive relations for the SPR connector elements.
Damage alarming analysis for ancient wood structures based on wavelet packet energy spectrum
Authors: Wang Xin , Bing Hu Wei , Bo Meng Zhao 
Published: October 2014

Purpose
– The purpose of this paper is to establish the damage alarming indexes for ancient wood structures and study the damage sensitivity and noise robustness of these indexes under random excitation.

Design/methodology/approach
– Xi’an Bell Tower is taken as a case in this paper to simulate the damage of ancient wood structures through finite element (FE) simulation and determine the satisfactory damage alarming indexes with wavelet packet energy spectrum.

Findings
– The results of this paper show that: 1) the damage alarming indexes can effectively identify the damage of ancient wood structures, each index with a different damage sensitivity; 2) the energy ratio deviation is greater than the energy ratio variance and is close to the maximum variation of energy ratio; 3) the energy ratio deviation has a better alarming effect than the energy ratio variance during the initial period of the damage. With the accumulation of the damage, the energy ratio variance outperforms the energy ratio deviation; 4) the sensitivity of the energy ratio deviation and variance varies from positions, changing from the highest to lowest at the mortise-and-tenon joints, the beam mid-span and the plinth; 5) if signal to noise ratio (SNR) is 40db or larger, the indexes can accurately identify the damage of ancient wood structures. As SNR increases, the indexes will have an increasingly higher sensitivity and certain ability to resist noise.

Research limitations/implications
– The FE model is simpiy, it does not completely reflect Xi’an Bell Tower.

Practical implications
– It will provide a theoretical basis for the damage alarming of Xi’an Bell Tower.

Social implications
– It makes structural health monitoring through structural vibration response under ambient excitation a new research field in damage detection as well as a positive way of ancient architecture protection.

Originality/value
– This paper studies the damage alarming effect on ancient wood structures from different wavelet functions and wavelet packet decomposition levels. To study the effect under white noise environment, this paper adds Gaussian white noise with a SNR of 10, 20, 30, 40 and 50 db to the acceleration response signal of intact structure and damaged structure.
All-atom molecular-level computational simulations of planar longitudinal shockwave interactions with polyurea, soda-lime glass and polyurea/glass interfaces
Authors: Grujicic Mica , Yavari Ramin , Snipes Jennifer , Ramaswami S. , Barsoum Roshdy 
Published: October 2014

Purpose
– The purpose of this paper is to study the mechanical response of polyurea, soda-lime glass (glass, for short), polyurea/glass/polyurea and glass/polyurea/glass sandwich structures under dynamic-loading conditions involving propagation of planar longitudinal shockwaves.

Design/methodology/approach
– The problem of shockwave generation, propagation and interaction with material boundaries is investigated using non-equilibrium molecular dynamics. The results obtained are used to construct basic shock Hugoniot relationships associated with the propagation of shockwaves through a homogeneous material (polyurea or glass, in the present case). The fidelity of these relations is established by comparing them with their experimental counterparts, and the observed differences are rationalized in terms of the microstructural changes experienced by the shockwave-swept material. The relationships are subsequently used to predict the outcome of the interactions of shockwaves with polyurea/glass or glass/polyurea material boundaries. Molecular-level simulations are next used to directly analyze the same shockwave/material-boundary interactions.

Findings
– The molecular-level simulations suggested, and the subsequent detailed microstructural analyses confirmed, the formation of topologically altered interfacial regions, i.e. polyurea/glass and glass/polyurea interphases.

Originality/value
– To the authors’ knowledge, the present work is a first attempt to analyze, using molecular-level simulation methods, the interaction of shockwaves with material boundaries.
Towards a critical study of standardization
Authors: George Bocean Claudiu , Delattre Miguel , Ocler Rodolphe , Soriana Sitnikov Catalina 
Published: October 2014

Purpose– This paper aims to highlight the links among standardization, corporate social responsibility (CSR) and critical management. It also aims at understanding the implication of the normalization process for CSR but also questions the nature of this concept.Design/methodology/approach– To determine the interest in standardization, we forecasted the trend in issuing ISO certificates based on autoregressive integrated moving average (ARIMA) and Holt statistical models. Then a critical approach is used to understand the nature of CSR.Findings– The paper focuses on a critical approach and challenge the definition of CSR through the lenses of standardization. It shows that the notion of CSR is polysemic and highlights the limits of standardization process.Research limitations/implications– The research is only based on ISO standards, not other kind of standardization process.Social implications– The paper questions the notion of CSR and shows the different elements that this notion covers.Originality/value– The paper questions the role of standardization and its impact on CSR adopting a critical view.
Bark beetles attacking conifer seedlings: picking on the weakest or feasting upon the fittest?
Authors: Sopow Stephanie L. , Bader Martin K.‐F. , Brockerhoff Eckehard G. 
Published: October 2014

SummaryPlant stress from causes such as drought is thought to increase the susceptibility of plants to herbivore attack and damage. Although this forms the basis of the widely cited plant stress hypothesis, there are few cases where this has been tested thoroughly.We compared the frequency of attack and damage of an invasive pine bark beetleHylates ater, on seedlings ofPinus radiata, using a 2 × 2 factorial design with artificially induced stress and insecticide application to distinguish effects of beetle attack and direct effects of stress.Contrary to expectations based on the plant stress hypothesis, twice as many unstressed seedlings (22%) were attacked than stressed seedlings (11%). However, stressed seedlings were twice as likely to experience sustained bark beetle feeding resulting in girdling, than unstressed seedlings (31% and 15%, respectively).In response to beetle attack, unstressed seedlings showed much stronger resin production than stressed seedlings, which is likely to explain the greater survival of unstressed seedlings after attack.Experimental drought stress caused a 50% reduction in shoot growth.Synthesis and applications. Maximizing seedling vigour and minimizing (pre‐)planting stress are key for the resilience of planted forests. Managers should emphasize a stress‐free transition of seedlings from nursery to field as well as correct planting techniques, in order to safeguard this vulnerable stage. This is particularly crucial since drought stress and insect invasions are likely to increase as a result of global change.

Authors: Golan Shani , Rosenfeld Eldar , Shemesh Gabi , Kurtz Shimon 
Published: October 2014

SummaryWe compared the intraocular pressure (IOP)‐lowering effect and safety profile of latanoprost (Xalatan) with its generic variant, Glautan (Unipharm, Tel Aviv, Israel). After 1 and 4 weeks of treatment, a randomized, prospective, cross‐over comparison was carried out that included patients with open‐angle glaucoma or ocular hypertension, either naïve or treated and well‐controlled, who were attending the Department of Ophthalmology, Tel Aviv Medical Centre, Tel Aviv, Israel, between May 2010 and November 2012. After a 3‐week washout period for the medicated subjects, the participants were randomized to 4 weeks of treatment with either Xalatan or Glautan once every evening and then, after a 3‐week washout period, crossed‐over to the other treatment for an additional 4 weeks. Efficacy was expressed by a change in intraocular pressure at three designated hours of the day after 1 week and 1 month of treatment, and tolerability was determined by ocular side‐effects as reported by the patient in a questionnaire. A total of 19 patients (mean age at initial diagnosis 66 ± 9 years, 14 females) were enrolled, of whom 17 had bilateral open‐angle glaucoma and two had unilateral disease. Both drugs lowered intraocular pressure after 1 week and 1 month (P = 0.06 and P = 0.04, respectively) of treatment. Xalatan had a tendency of greater efficacy than Glautan both after 1 week and 1 month, but the difference was not statistically significant (P =0.69 and P = 0.34, respectively). Drug safety was similar for Xalatan or Glautan, but more ocular side‐effects were reported after treatment with Glautan (21 vs 12 for Xalatan, P = 0.06).
