Coronary Artery Bypass Grafting during Acute Coronary Syndrome: Outcomes and Comparison of Off-Pump to Conventional Coronary Artery Bypass Grafting at a Veteran Affairs Hospital
Authors: Emerson Dominic A. , Hynes Conor F. , Greenberg Michael D. , Trachiotis Gregory D. 
Published: July 2015

Objective The management of acute coronary syndrome (ACS) has evolved dramatically over the last 50 years. Currently, management includes a multidisciplinary approach potentially including catheter-based therapy, surgery, or purely medical management. Where surgical therapy is indicated, data regarding long-term outcomes are limited. In particular, little data exist regarding on-pump (conventional coronary artery bypass grafting, cCABG) versus off-pump (OPCABG) outcomes for this group. Methods A retrospective review of prospectively collected data was undertaken. Patients undergoing isolated CABG from January 2000 to December 2011 with ACS were identified (n = 271); non-ACS patients (n = 854) were established as a control. Data were analyzed with a χ2 or a t test, where appropriate. Survival was compared using Kaplan-Meier analysis and Cox proportional hazards model. Results Thirty-day mortality between the ACS and the control groups was similar; however, long-term mortality was worse for the ACS group ( P = 0.032; median follow-up, 5.5 years). Length of stay and composite morbidity were higher in the ACS group ( P < 0.01). Subgroup analysis of ACS patients (OPCABG vs cCABG) demonstrated worse preoperative comorbidities in the OPCABG group, but similar 30-day and long-term mortality. However, the cCABG group had higher rates of reoperation ( P = 0.034) and longer length of stay ( P = 0.017) and operative time ( P < 0.0001). Cox proportional hazards model was applied. Risk factors for the non-ACS cohort included age, diabetes, OPCABG, and ACS ( P < 0.05). Among the ACS cohort, only age remained a statistically significant factor ( P < 0.0001). Conclusions ACS appears to negatively impact long-term, but not short-term, mortality. Within the ACS group, OPCABG compares favorably to cCABG in the long-term and also improves short-term morbidity.
Determinants of patient safety, satisfaction and trust
Authors: Zineldin Mosad 
Published: July 2015

Purpose
– The purpose of this paper is to assess and examine the impact of physicians-nurses performance on patient perceptions on safety, trust and satisfaction.

Design/methodology/approach
– A cross-sectional study of 170 inpatients at 78 Chinese hospitals has been conducted. A structured questionnaire covering multiple constructs was used to collect the data. Methodology is described and results are discussed.

Findings
– Multivariate regression results show that despite the variations in education and training of physicians and nurses, trust is statistically significant in the models with doctors performance and nurses performance as dependent variables. One surprise result is that patient safety is not statistically significant in the regression model with NP as dependent variable.

Practical implications
– Doctor and nurses as well as other staff at any healthcare setting or ward should provide patients with high-quality and safe healthcare. Competences and performance of physicians and nurses are the primary source of patient safety.

Social implications
– The patient correlate their patients safety with doctors but not with nurses. On the other hand, they relate their satisfaction more to nurses performance than doctors performance.
Aligning the talent development and succession planning processes: don’t allow critical leadership talent to fall by the wayside
Authors: Newhall Steve 
Published: July 2015

Purpose
– Organizations need to take a holistic view of their talent management programs, and it’s no longer sufficient to simply look at the top layers of leadership (succession planning). High potentials need to be identified early and customized plans put in place to ensure that their development is aligned to the business strategy.

Design/methodology/approach
– Based on a global study commissioned by Korn Ferry and conducted by Hanover research during August and September 2014. The survey covered 54 countries globally and companies ranging in size from 500 to 50,000+ employees. It generated more than 1,000 responses from business leaders at the following levels: C-suite (41 per cent), VP/SVP/EVP (42 per cent), Director (11 per cent) and Other (6 per cent).

Findings
– Only one third of those surveyed reported they are satisfied with the outcomes of their succession programs and the majority end up recruiting externally more often than they would like to obtain the talent they need. Analysis of current versus future skills requirements is rarely done and promotions are awarded on current performance rather than future potential. Development plans are not differentiated neither are they dynamically managed. A structured and systematic approach is needed, starting earlier in employees’ careers to ensure those who have the greatest potential are ready when they need to be.

Originality/value
– Organizations typically recruit externally more often than they would wish. This article, through analysis of the survey results, highlights the need for a more holistic approach with early intervention and differentiated development.
Enhancing the value of training: creating closer time linkages between training acquisition, application and compensation
Authors: Simpson Jim , Schraeder Mike , Borowski Martha 
Published: July 2015

Purpose
– This article reinforces the importance of a strategic approach to training as a method of increasing the potential value of training. The strategic approach presented in the article includes timely linkages between the acquisition of training, the application of training, and rewards/compensation associated with training.

Design/methodology/approach
– The importance of training as an investment is discussed, followed by a summary/illustration of an example of a training program in a financial services organization that did not result in desired returns or value associated with the investment in training.

Findings
– Time lags between the acquisition of training and opportunities to apply the knowledge, skills, and capabilities developed through the training may have negative implications on employee perceptions and potential value associated with the training.

Practical implications
– The article provides interesting insights to leaders, human resource professionals, and others involved in employee training programs. Specific emphasis is placed on the importance of linking compensation and opportunities to apply/transfer knowledge with training acquisition in a timelier manner.

Originality/value
– The importance/value of applying knowledge, skills, and capabilities obtained through training is a recurring theme in the literature. The role of rewards in the form of compensation associated with training and knowledge acquisition is also widely noted. This article extends our understanding of these factors by placing emphasis on more closely linking the timing of training acquisition, application, and compensation in an effort to enhance the potential, strategic value of training investments.
Support your local communities of practice
Authors: Bandow Diane , Gerweck Joseph T 
Published: July 2015

Purpose
– This paper provides considerations for organizations interested in supporting knowledge sharing among employees based on experiences and recent research. Experiences emphasize the need to discover and recognize unofficial communities of practice; support distributed leadership; support control of the communities by their members; enable interaction and learning opportunities; consider social media carefully; leaving choices up to the community members; and an approach to calculating the value of communities of practice (CoPs) based on knowledge management.

Design/methodology/approach
– The approach of this paper focuses on six basic themes from research and experiences in the literature with CoPs. Lessons learned and recommendations are provided.

Findings
– Lessons from CoPs focus on the need for distributed leadership or all engage, participate and share responsibilities; control of the community belongs to the members, and they decide membership; interaction and learning opportunities are essential to support competitive advantage for the organization and continuous development for the community members. Social media is unproven in the workplace and should be approached carefully, as the CoP must determine benefits and advantages. An approach to calculating value is proposed, based on calculating the value of knowledge management.

Practical implications
– As CoPs continue to evolve, organizations play a key role in supporting their development which in turn provides competitive advantage for the organization. Continuous learning and development are the key aspects of these communities, including opportunities for leadership, decision-making and professional development. Technology can play an important role in CoPs, but must be supported by the membership. The return on investment (ROI) may be significant and learning opportunities provide the potential for personal development and the enhancement of organizational performance.

Originality/value
– This review offers insights into experiences and findings from CoPs, supports distributed leadership and control of the community among the members, strongly recommends interaction and learning opportunities and addresses social media as a possibility to support the CoP. The ROI potential supports and encourages organizations to develop employees and enhance overall performance.
Robust and efficient handling of yield surface discontinuities in elasto-plastic finite element calculations
Authors: Clausen Johan , Damkilde Lars , Andersen Lars Vabbersgaard 
Published: July 2015

Purpose– The purpose of this paper is to present several methods on how to deal with yield surface discontinuities. The explicit formulations, first presented by Koiter (1953), result in multisingular constitutive matrices which can cause numerical problems in elasto-plastic finite element calculations. These problems, however, are not documented in previous literature. In this paper an amendment to the Koiter formulation of the constitutive matrices for stress points located on discontinuities is proposed.Design/methodology/approach– First, a review of existing methods of handling yield surface discontinuities is given. Examples of the numerical problems of the methods are presented. Next, an augmentation of the existing methods is proposed and its robustness is demonstrated through footing bearing capacity calculations that are usually considered “hard”.Findings– Previous studies documented in the literature all present “easy” calculation examples, e.g. low friction angles and few elements. The amendments presented in this paper result in robust elasto-plastic computations, making the solution of “hard” problems possible without introducing approximations in the yield surfaces. Examples of “hard” problems are highly frictional soils and/or three-dimensional geometries.Originality/value– The proposed method makes finite element calculations using yield criteria with corners and apices, e.g. Mohr-Coulomb and Hoek-Brown, much more robust and stable.
Strict upper and lower bounds of quantities for beams on elastic foundation by dual analysis
Authors: Wang Li , Guo Mengwu , Zhong Hongzhi 
Published: July 2015

Purpose
– The purpose of this paper is to acquire strict upper and lower bounds on quantities of slender beams on Winkler foundation in finite element analysis.

Design/methodology/approach
– It leans on the dual analysis wherein the constitutive relation error (CRE) is used to perform goal-oriented error estimation. Due to the coupling of the displacement field and the stress field in the equilibrium equations of the beam, the prolongation condition for the stress field which is the key ingredient of CRE estimation is not directly applicable. To circumvent this difficulty, an approximate problem and the solution thereof are introduced, enabling the CRE estimation to proceed. It is shown that the strict bounding property for CRE estimation is preserved and strict bounds of quantities of the beam are obtainable thereafter.

Findings
– Numerical examples are presented to validate the strict upper and lower bounds for quantities of beams on elastic foundation by dual analysis.

Research limitations/implications
– This paper deals with one-dimensional (1D) beams on Winkler foundation. Nevertheless, the present work can be naturally extended to analysis of shells and 2D and 3D reaction-diffusion problems for future research.

Originality/value
– CRE estimation is extended to analysis of beams on elastic foundation by a decoupling strategy; strict upper bounds of global energy norm error for beams on elastic foundation are obtained; strict bounds of quantities for beams on elastic foundation are also obtained; unified representation and corresponding dual analysis of various quantities of the beam are presented; rigorous derivation of admissible stresses for beams is given.
Small firm growth as a function of both learning orientation and entrepreneurial orientation
Authors: Wolff James A. , Pett Timothy L. , Ring J. Kirk 
Published: July 2015

Purpose– The purpose of this paper is to investigate the relationship between learning orientation (LO), entrepreneurial orientation (EO), and firm growth in small- and medium-sized ﬁrms (SMEs). The authors theoretically argue for a mediation effect of EO on the relationship between LO and growth. The study considered how companies that value learning enact actions to affect firm outcomes. This is particularly important for small firms that may not be capable of withstanding significant shocks in the marketplace.Design/methodology/approach– The research design employed the survey method for data gathering and resulted in 105 completed responses from CEOs/presidents of SMEs. To examine the construct validity of the measurement dimensions the authors used a multistage process. Additionally, the authors employed a competing models analytic design to determine the presence and strength of mediating effects of the EO construct.Findings– The findings empirically demonstrate the notion that firm cultural values embodied in a LO and translated into action behaviors by an EO is positively related to SME growth and adaptation. The research also supports the notion that learning is an important element in opportunity recognition insofar as opportunity recognition is entrepreneurial or reflecting an EO. SMEs that are open to learning may identify opportunities to exploit through an EO that facilitates growth. In the face of dynamic external environments and competitive conditions SMEs are well served by being more creative and entrepreneurial.Research limitations/implications– The design of the study is limited by single source, key respondents in SMEs, and has the potential for common method bias even though the authors tested for this effect successfully.Originality/value– The study contributes to the literature by examining how learning and an orientation toward entrepreneurial behavior affect the growth of firms. These findings will be of value to both scholars and entrepreneurs.

Authors: Seah Melody , Hsieh Ming Huei 
Published: July 2015

Purpose– This paper aims to explore the impact of leadership on organizational change and adaptability in a Chinese business context. Drawing on case data, this study seeks to uncover the factors that would predispose the leaders of Chinese family firms to initiate and implement organizational change and adaptation.Design/methodology/approach– This study is based on 16 in-depth interviews held with key informants from the case firm. Evidence is presented in the form of interview extracts.Findings– Research findings indicate that Chinese firm leaders can successfully facilitate organizational change by adapting their styles to match the changes in the business environment.Research limitations/implications– The issues identified are explored within a single case study setting, hence future research might replicate these findings to other samples or settings.Practical implications– To lead organizational change, leaders must first be able and willing to adjust their leadership styles to match the demands of their changing business environments.Originality/value– This paper adds insight to existing literature on leadership, organizational change and firm turnarounds. This paper also provides an in-depth insight into the factors that influence the leadership and management Chinese family firms.
Place brand love and marketing to place consumers as tourists
Authors: Swanson Kathryn 
Published: July 2015

Purpose
– The purposes of this paper are to outline the theoretical context for the study of brand love in the context of places and to report preliminary findings from an extensive study on place brand love.

Design/methodology/approach
– Three places were chosen for the research: Orlando, Florida; Minneapolis, Minnesota; and Las Vegas, Nevada. A study sample of 20 consumers engaged in a variety of methodological techniques including semi-structured consumer interviews, volunteer-employed photography and consumer collage creation.

Findings
– Thirteen primary themes through which participants articulated their love in respect of the places under study were identified. These can be grouped into four categories: antecedents, relational themes (involving relationships between others, oneself and the place), experiential themes (relating to the experience of being at the place) and outcomes.

Originality/value
– ‘Brand love’ is an aspect of branding that has not been explored in the context of places, and preliminary results indicate that this may be a useful concept for both academics and practitioners to investigate further.
Places, users, and place uses: a theoretical approach to place market analysis
Authors: Rozhkov Kirill Lvovich , Skriabina Natalya Il’inichna 
Published: July 2015

Purpose
– This paper aims to develop a theoretical approach to place market analysis that aims to identify the ways in which specific places are used and to further enable the identification of distinct segments and products.

Design/methodology/approach
– Typology construction was chosen as the main study method. Eight polar place demand patterns were classified on the abstract level, using a set of binary variables of spatial behaviour (migration, natural growth and settling). Based on this typology, eight abstract places were deductively described. In conjunction with this deductive study, the authors conducted focus groups, and the results showed considerable similarity in the interpretation of the achieved types.

Findings
– This paper arrives at interdependent typologies of place demand, place product and place use patterns that allow the ways of using specific places to be identified and distinctive segments and products to be distinguished as particular, consistent combinations of the achieved types.

Practical implications
– The typologies obtained expand the scope of competitive analysis and planning in framing place marketing. Distinct uses of specific places unambiguously point to the features of certain segments and could thereby enable a lucid marketing strategy.

Originality/value
– Empirically driven place market research has not precisely defined the distinct ideas and concepts of investigated places, which might reflect the different segments of the population that have different intentions for the use of these places. This paper offers important insights into product differentiation and market segmentation in the frame of simultaneous product use.
Pricing competitiveness of jump-diffusion option pricing models: evidence from recent financial upheavals
Authors: Singh Vipul Kumar 
Published: July 2015

Purpose
– The purpose of this paper is to investigate empirically the forecasting performance of jump-diffusion option pricing models of (Merton and Bates) with the benchmark Black–Scholes (BS) model relative to market, for pricing Nifty index options of India. The specific period chosen for this study canvasses the extreme up and down limits (jumps) of the Indian capital market. In addition, equity markets keep on facing high and low tides of financial flux amid new economic and financial considerations. With this backdrop, the paper focuses on finding an impeccable option-pricing model which can meet the requirements of option traders and practitioners during tumultuous periods in the future.

Design/methodology/approach
– Envisioning the fact, the all option-pricing models normally does wrong valuation relative to market. For estimating the structural parameters that governs the underlying asset distribution purely from the underlying asset return data, we have used the nonlinear least-square method. As an approach, we analyzed model prices by dividing the option data into 15 moneyness-maturity groups – depending on the time to maturity and strike price. The prices are compared analytically by continuously updating the parameters of two models using cross-sectional option data on daily basis. Estimated parameters then used to figure out the forecasting performance of models with corresponding BS and market – for pricing day-ahead option prices and implied volatility.

Findings
– The outcomes of the paper reveal that the jump-diffusion models are a better substitute of classical BS, thus improving the pricing bias significantly. But compared to jump-diffusion model of Merton’s, the model of Bates’ can be applied more uniquely to find out the pricing of three popularly traded categories: deep-out-of-the-money, out-of-the-money and at-the-money of Nifty index options.

Practical implications
– The outcome of this research work reveals that the jumps are important components of pricing dynamics of Nifty index options. Incorporation of jump-diffusion process into option pricing of Nifty index options leads to a higher pricing effectiveness, reduces the pricing bias and gives values closer to the market. As the models have been tested in extreme conditions to determine the dominant effectuality, the outcome of this paper helps traders in keeping the investment protected under normal conditions.

Originality/value
– The specific period chosen for this study is very unique; it canvasses the extreme up and down limits (jumps) of the Indian capital market and provides the most apt situation for testifying the pricing competitiveness of the models in question. To testify the robustness of models, they have been put into a practical implication of complete cycle of financial frame.
