Abstract
Radlinski, M. K., Sundermeyer, M. A., Bisagni, J. J., and Cadrin, S. X. 2013. Spatial and temporal distribution of Atlantic mackerel (Scomber scombrus) along the northeast coast of the United States, 1985–1999. – ICES Journal of Marine Science, 70: 1151–1161. The distribution of Atlantic mackerel (Scomber scombrus) during their spring migration along the Mid-Atlantic Bight and into the Gulf of Maine has historically been associated with spring warming along the continental shelf. Variations in mackerel distributions based on National Marine Fisheries Service spring surveys were compared with variations in sea surface temperature (SST) from satellite remote sensing for the eastern US continental shelf for the period 1985–1999. The mackerel stock was first analysed as a unit, then separated into three size classes to assess differences in distribution among years and individuals of various lengths. Results showed an across-shelf correlation between catch and March SST in the Mid-Atlantic Bight for both the entire population and each size class. Along-shelf catch variations were correlated with SST for large mackerel, but not total stock or smaller size classes. Finally, the distribution of mackerel length in the Gulf of Maine was negatively correlated with March SST in the Great South Channel. Results suggest surface temperature along the northeast continental shelf may be used to predict certain, but not all, aspects of annual migration along the shelf, and that factors in addition to temperature are also important in controlling distributions of Atlantic mackerel.

Authors: Kuram Emel , Ozcelik Babur , Tolga Simsek Bilgin , Demirbas Erhan 
Published: April 2013

PurposeThe purpose of this paper is to investigate the performances of vegetable based cutting fluids by comparing tool life, surface roughness and cutting force during end milling of AISI 304 stainless steel. In the experiments, three different vegetable based cutting fluids developed from sunflower and canola oils (SCF‐II with 8% extreme pressure (EP), CCF‐II without EP and CCF‐II with 8% EP) and a commercial type of semi‐synthetic cutting fluid were used. Cutting fluid was applied to the cutting zone via two nozzles.Design/methodology/approachEffects of different cutting speeds (100, 150 and 200 m/min) and different feed rates (0.2, 0.25 and 0.3 mm/rev) on tool life, surface roughness and cutting force in milling of AISI 304 stainless steel were investigated. Depth of cut and step over were kept constant as 0.3 mm and 10 mm at both conditions, respectively.FindingsResults indicated that CCF‐II with 8% EP cutting fluid showed better performance than the others.Originality/valueIn this study, effect of extreme pressure additive on milling performance was investigated.
IS curriculum career tracks: a UK study
Authors: Stefanidis Angelos , Fitzgerald Guy , Counsell Steve 
Published: April 2013

PurposeThe purpose of this paper is to present the results of a comprehensive study on the specialisations or career tracks supported by the Information Systems (IS) curriculum in the UK.Design/methodology/approachThe study utilises the recently published IS curriculum guidelines (IS 2010) to develop a method for ranking the career tracks of undergraduate IS courses in the UK.FindingsThe research presents a prioritised list of graduate IS careers by taking into account the entire IS course provision in the UK. At the same time, it offers data about the size of the IS curriculum in terms of universities in the UK and the number/type courses they offer.Research limitations/implicationsThe study relies on a previously undeveloped method for measuring career specialisations for UK IS graduates. Additional work is needed to validate the results through comparisons with alternative methods of measuring the careers supported by IS degree courses.Practical implicationsBy having concrete data about the state of the IS curriculum in relation to its employability opportunities, the IS academy can make more informed decisions about future curriculum development. Further comparative research can be undertaken to support arguments about the relevance of the IS curriculum to industry needs.Originality/valueThere has been no similar UK study on this scale which examines the state of the IS curriculum in relation to the career opportunities it offers. The development of the method for this study also offers insights into the structure and recommendations presented by IS 2010.
Entrepreneurial motivations and intentions: investigating the role of education major
Authors: Solesvik Marina Z. 
Published: April 2013

PurposeThe purpose of this study is to explore the difference in entrepreneurial intentions, perceived entrepreneurial motivation, and cognitive profiles (attitudes towards entrepreneurship, perceived behaviour control, and subjective norms) between individuals who have participated in enterprise education programmes in the universities and those who have not. The paper also investigates the mediating role of attitudes towards entrepreneurship, perceived behaviour control, and subjective norms related to entrepreneurial motivation and the forming of entrepreneurial intentions.Design/methodology/approachSurvey information from 321 students from three universities in the Ukraine was hand collected. Hierarchical multiple regressions were used to test hypotheses.FindingsIndividuals who participate in enterprise programmes tend to have higher entrepreneurial motivation and are more likely to become entrepreneurs. Empirical evidence shows that attitudes, subjective norms and perceived behaviour control mediate the relationship between perceived entrepreneurial motivation and entrepreneurial intentions.Research limitations/implicationsThe study is based on data collected from three universities in one city. The implications for education managers related to the inclusion of enterprise courses into the study plans of engineering students are also discussed here.Practical implicationsThe findings have implications for the stimulation of student enterprise in transitional economies where attitudinal and resource (i.e. skill, competence and knowledge) deficiencies can retard enterprise. Entrepreneurial motivation is an important link between an intention and action. Enterprise education programs which stimulate entrepreneurial motivation should be offered to engineering students since many of them start ventures later. Engagement into enterprise development programs of engineering students might evoke earlier interest in self‐employment career path among young people.Originality/valueThe article contributes to the field of entrepreneurial motivation and intentions. The study extends insights from the theory of planned behaviour (TPB) (i.e. subjective norms, attitudes toward this behaviour, and perceived behavioural control) by also considering the perceived entrepreneurial motivation profiles of students.
The influence of training and training transfer factors on organisational learning and performance
Authors: Dermol Valerij , Čater Tomaž 
Published: April 2013

PurposeThe study aims to contribute to the training‐related literature by investigating the relationship between training and training transfer factors and company‐level training outcomes, and the relationship between the latter and company performance.Design/methodology/approachThe authors propose and test a model linking constructs related to training (the volume and quality of training, supervisor support, peer support, and organisational incentives), constructs related to company‐level training outcomes (the acquisition and interpretation of information, and cognitive and behavioural changes) and company performance. In the empirical analysis the authors use structural equation modelling based on a sample of 247 service companies.FindingsThe study confirms a strong relationship between supervisor support and the volume and quality of training as well as between supervisor support and organisational incentives for training transfer. Organisational incentives are directly related to both studied company‐level training outcomes, i.e. the acquisition and interpretation of information, and cognitive and behavioural changes. In addition, they are also indirectly related to company performance through encouraging cognitive and behavioural changes. The volume and quality of training are related only to the acquisition and interpretation of information, while no direct relationship with company performance was found.Research limitations/implicationsThe study sends an important message to CEOs and HR managers showing them that companies should focus not only on the volume and quality of training but also on important training‐transfer‐related factors.Originality/valueThe study complements previous studies dealing with the relationship between training and performance by clearly distinguishing between training and training transfer factors, and by studying their combined relationship with company‐level training outcomes and, through that, with company performance. The links in the model are addressed in a way that has not yet been used in existing literature.
Internal lean practices and operational performance
Authors: Chavez Roberto , Gimenez Cristina , Fynes Brian , Wiengarten Frank , Yu Wantao 
Published: April 2013

PurposeThe purpose of this research is to examine the effect of internal lean practices on multiple operational performance dimensions, and assess the contingency perspective of these relationships with respect to industry clockspeed.Design/methodology/approachThe study is based on empirical data gathered from 228 manufacturing companies in the Republic of Ireland. The relationships between the constructs are analyzed through regression analysis.FindingsThe results indicate that the relationships between internal lean practices and quality, delivery, flexibility and cost were found to be positive and significant. Further, industry clockspeed was found to moderate the relationship between internal lean practices and quality, delivery and flexibility, but not cost.Practical implicationsWhile internal lean practices can improve operational performance, managers should be aware that internal lean practices are not universally applicable, and the rate of change within an industry should be considered at the time of implementing lean principles.Originality/valueMuch of the lean literature tends to be biased towards its effectiveness. However, empirical evidence shows that not all lean implementation have led to positive results, which has been attributed to the general complexity in the relationship between internal lean practices and performance. We propose to investigate further this relationship by disaggregating operational performance into four of its dimensions, namely quality, delivery, flexibility and cost, and by investigating the possible contingency effect of industry clockspeed.
Experiential learning: inspiring the business leaders of tomorrow
Authors: Baden Denise , Parkes Carole 
Published: April 2013

PurposeThe complex challenges of sustainable development and the need to embed these issues effectively into the education of future business leaders has never been more urgent. The purpose of this paper is to discuss different approaches taken by two UK signatories to the UN Principles for Responsible Management Education (PRME).Design/methodology/approachThe two approaches examined are: MSc Entrepreneurship students opting for placements with social enterprises; and MBA students undertaking workshops using “live” case studies. A content analysis of the experiences of students from their written reflective narratives is presented. This is supplemented by reflections of the facilitators and tutors.FindingsThe analysis reveals that the opportunity to work with social entrepreneurs and/or “responsible” business professionals provides the business students with inspirational role models and positive social learning opportunities.Research limitations/implicationsThis paper suggests that experiential learning is an effective way of integrating ethics, responsibility and sustainability into the curriculum but the research draws on the experience of two schools. Further research is important to explore these findings in other contexts.Practical implicationsThe authors argue that direct exposure to a business culture (and/or behaviour) that is predicated upon ethical/social responsibility and sustainability is an effective means to embed these values in the curriculum.Originality/valueThis paper contributes by drawing on social psychological research related to behaviour change to examine how experiential learning on traditional Business Masters programmes can provide students with the knowledge, motivation and skills to contribute positively to society, in a way that more traditional pedagogies cannot.
Knowledge combination, innovation, organizational performance in technology firms
Authors: María Ruiz‐Jiménez Jenny , del Mar Fuentes‐Fuentes María 
Published: April 2013

PurposeThe purpose of this paper is to explore the effects of product and process innovation on the relationships between knowledge combination capability and organizational performance.Design/methodology/approachThe data were collected from small and medium‐sized enterprises (SMEs) belonging to the sector of Spanish technology‐based firms (TBFs). This study employs the structural equation model (SEM) to examine the relationships between product and process innovation, knowledge combination capability, and organizational performance.FindingsThe findings of this study suggest, first, that knowledge combination capability has a significant impact on product and process innovation. Second, product and process innovation mediate the relations between knowledge combination capability and organizational performance.Research limitations/implicationsThe sample includes only firms in the technology sector; future studies could analyze another kind of organization. Further studies might also use a wider sample that encompasses several countries.Practical implicationsThis paper implies that, to achieve better performance in technology SMEs, the managers should focus more on knowledge combination capability to improve innovation, as this is the key to excellent business performance.Originality/valueThis study contributes to the literature on innovation and knowledge. It examines the mediating effects of product and process innovation, knowledge combination capability, and organizational performance in technology SMEs. The research demonstrates empirically that innovation strengthens the effect of knowledge on firm performance in the sector studied.
High‐speed broadband: assessing its social impact
Authors: Rampersad Giselle , Troshani Indrit 
Published: April 2013

PurposeGiven the increasingly significant investments in high‐speed broadband (HSB) internationally and the heightened rhetoric surrounding its benefits, the purpose of this paper is to assess the social impact of HSB.Design/methodology/approachBased on a case study concerning HSB delivered in the ambit of Australia's National Broadband Network (NBN), the study contributes a conceptual framework to evaluate the social impact of HSB initiatives.FindingsThe authors found that key sectors, including education, health and community development, should be critically assessed across pertinent dimensions in evaluating the social impact of HSB.Practical implicationsThe framework provided in this study is significant as it can be used strategically by managers and policy makers in both leveraging HSB opportunities in key sectors and monitoring the performance of such initiatives.Originality/valueThe research extends the technology adoption literature by contributing a framework that moves beyond the individual and organizational levels of technology adoption towards the wider sectoral level; and second, attempts to examine post‐adoption impact of technology.
Computer‐supported collaborative learning: a research framework
Authors: Long Yuan , Fui‐Hoon Nah Fiona , Eschenbrenner Brenda , Schoonover Terrance 
Published: April 2013

PurposeThe purpose of this paper is to propose a computer‐supported collaborative learning (CSCL) research framework.Design/methodology/approachThe framework was developed from a review and synthesis of the literature. More specifically, gaps in the literature were identified and a general framework for future CSCL research was proposed.FindingsThis paper proposes a research framework that identifies a fit profile between learning objectives, learning tasks, and technology in CSCL. The fit profile, in turn, is expected to influence users' learning processes and outcomes.Research limitations/implicationsThis framework can serve as a foundation for future research in CSCL. More specifically, research should give consideration to the collaborative learning objective and task, which will vary in degrees of complexity and cognitive demands. Also, researchers will want to evaluate the level of sophistication of the CSCL technology, as well as its appropriateness for a given objective and task, which ultimately influences the learning process and outcomes.Practical implicationsConsiderations and guidelines for development of CSCL applications are provided.Originality/valueCSCL is an important research area that has attracted the attention of researchers from various disciplines (e.g. information systems, educational psychology). However, the findings are varied and sometimes conflict with each other. By emphasizing a fit profile between learning objectives, learning tasks, and technology, this paper proposes a theory‐based research framework to address the inconsistencies observed in the literature.
Going‐concern audit opinions for bankrupt companies – impact of credit rating
Authors: Feldmann Dorothy , Read William J. 
Published: April 2013

PurposeThe purpose of this study is to examine whether credit ratings inform auditors' going‐concern (GC) audit opinions for companies facing imminent bankruptcy.Design/methodology/approachUsing data from BankruptcyData.com the authors identify US publicly‐held, financially‐distressed companies that filed bankruptcy from January 1, 2000 through June 30, 2009. Logistic regression is applied by regressing audit opinion type on select financial, industry, and credit rating data.FindingsResults show that the likelihood of an auditor issuing a GC opinion is associated with the credit rating issued by Standard & Poor's (S&P) preceding the audit report date. In results supporting the idea that the auditor's opinion has informational value, the paper also finds that after issuance of a GC report, S&P's credit rating tends to be downgraded.Research limitations/implicationsWhile the findings indicate observable relationships between audit opinions and credit ratings, the models used in primary analysis cannot determine causality.Originality/valueThis study sheds some light on how credit ratings and audit opinions may be inter‐related in distressed companies, an issue previously not investigated in the literature.
Recent developments in exchange‐traded fund literature
Authors: Charupat Narat , Miu Peter 
Published: April 2013

PurposeThe purpose of this paper is to provide a brief review of three strands of the literature on exchange‐traded funds.Design/methodology/approachThe paper starts with a review of the history of the growth of exchange‐traded funds and their characteristics. The paper then examines the key factors and findings of the existing studies on, respectively, the pricing efficiency, the tracking ability/performance, and the impact on underlying securities of exchange‐traded funds.FindingsAlthough there has been a substantial amount of research conducted to advance our knowledge on the trading, management, and effect of exchange‐traded funds, the findings are still far from conclusive in addressing a number of research questions.Practical implicationsInvestors and other market participants will find this review informative in enhancing the understanding of exchange‐traded funds.Originality/valueBy highlighting the general theme of the related research findings, the paper provides a systematic review of the existing literature that future researchers can utilize in developing their research agenda.
Transient electromagnetic field, losses and forces in a synchronous turbogenerator rotor
Authors: Pantelyat Michael G. , Bíró Oszkár , Stermecki Andrej 
Published: April 2013

PurposeThe paper seeks to present a methodology of computer simulation of 3D transient electromagnetic fields, losses and forces due to negative sequence currents in fragments of large synchronous turbogenerator rotors. The methodology allows for the preparation of initial data for further computations of thermal and mechanical behaviour of rotors.Design/methodology/approachThe governing equations for 3D negative sequence transient electromagnetic fields with the Coulomb gauge using magnetic vector potential and scalar electric potential A, V – A are solved by the nodal finite element method in a Cartesian coordinate system moving synchronously with the rotor.FindingsThe presented methodology of 3D transient electromagnetic phenomena computation seems to be effective because the electromagnetic field in the rotor of a synchronous generator is generally three dimensional, and therefore 2D field‐computation approaches and software are not able to simulate intrinsically 3D electromagnetic processes in turbogenerator rotors.Research limitations/implicationsCurrently it is difficult to carry out accurate numerical simulation of 3D transient electromagnetic fields and therefore losses and forces within the whole structure of the rotor because of the resulting huge computational expenses. This paper is devoted to the finite element analysis of electromagnetic fields, losses and forces in separate structural parts of the rotor. As an example of practical utilization of the developed technique, the computer simulation of electromagnetic phenomena in junctions of nonmagnetic rotor slot wedges of a 300 MVA class synchronous turbogenerator is carried out.Practical implicationsThe methodology can successfully be used during the design process of modern large synchronous turbogenerators.Originality/valueThis paper presents numerical analysis of intrinsically 3D transient electromagnetic phenomena in large turbogenerator rotors.
