Joule heating effect on magnetohydrodynamic mixed convection boundary layer flow with variable electrical conductivity
Authors: Hossain Anwar , Subba Reddy Gorla Rama 
Published: March 2013

PurposeThe paper's aim is to investigate the mixed convection flow of an electrically conducting and viscous incompressible fluid past an isothermal vertical surface with Joule heating in the presence of a uniform transverse magnetic field fixed relative to the surface. It was assumed that the electrical conductivity of the fluid varies linearly with the transverse velocity component.Design/methodology/approachThe governing boundary layer equations were solved numerically. The boundary layer equations were first reduced to a convenient form by using two different formulations, namely, (i) the stream function formulation (SFF) and (ii) primitive variable formulation (PVF).FindingsIt was observed that both the local shear‐stress and Nusselt number increase with increasing value of local magnetic parameter, ξ.Research limitations/implicationsIn the present investigation, we investigated the effects of Joule heating on MHD mixed convection boundary layer flow of an electrically conducting viscous incompressible fluid past an isothermal vertical flat plate in the presence of a transverse magnetic field fixed relative to the surface of the plate. The analysis was valid for a steady, two dimensional laminar flow. An extension to three dimensional flow case is left for future work.Practical implicationsHere we have analyzed the problem of mixed convection flow of electrically conducting and viscous incompressible fluid past an isothermal vertical surface with viscous and Joule heating in presence of a uniform transverse magnetic field fixed relative to the surface. The work would be useful in the thermal management of heat transfer devices.Originality/valueThe results of this study may be of interest to engineers interested in heat exchanger design.

Authors: Shadloo M.S. , Kimiaeifar A. , Bagheri D. 
Published: March 2013

PurposeThe purpose of this paper is to study a two‐dimensional steady convective flow of a micropolar fluid over a stretching sheet in the presence of radiation with constant temperature.Design/methodology/approachThe corresponding momentum, microrotation and energy equations are analytically solved using homotopy analysis method (HAM).FindingsTo validate the method, investigate the accuracy and convergence of the results, a comparison with existing numerical and experimental results is done for several cases. Finally, by using the obtained analytical solution, for the skin‐friction coefficient and the local Nusselt number as well as the temperature, velocity and angular velocity, profiles are obtained for different values of the constant parameters, such as Prandtl number, material, boundary and radiation parameter.Originality/valueIn this paper, a series solution is presented for the first time.
Using the repertory grid technique to surface strategic planning assumptions
Authors: Timothy Few W. , Few Molly 
Published: March 2013

PurposeIn his article titled, “The theory of the business,” Peter Drucker suggests that organizations need to frequently challenge the assumptions underlying their theory of the business (TOB) in order to assure that it remains viable. Accordingly, the purpose of this paper is to introduce the repertory grid technique (RGT) and illustrate how it can be used as a strategic planning tool to surface the assumptions underlying an organization's TOB.Design/methodology/approachThe RGT's merits as a planning tool are demonstrated through a case study involving the president of a Pittsburgh‐based financial services organization. Specifically, this case study describes how the RGT and the organization's competitors were used to surface the assumptions underlying the organization's TOB.FindingsThe paper describes how the assumptions surfaced from this case study can be used to challenge the organization's TOB. Furthermore, guidance is offered as to how the RGT can be integrated into an organization's strategic planning process and a list of resources that one can refer to for further information concerning the RGT is provided.Originality/valueWhile the RGT has been used by scholars as a research tool and various authors have suggested that it can be used to address various organizational challenges (e.g., implementing a new system), no one to date has demonstrated its value as a strategic planning tool. Consequently, the paper is a valuable resource for practitioners, as well as academics and consultants who provide strategic planning services to organizations.
Macroeconomic policy, localization and reducing unemployment
Authors: Sherif Souad 
Published: March 2013

PurposeThe purpose of this paper is to analyze the unique unemployment anomaly in the UAE and formulate a long‐term, comprehensive strategy to combat effectively the high rates of unemployment among UAE citizens through a national policy.Design/methodology/approachThe policy recommendations of this study constitute a package of interrelated policies designed carefully to provide a long‐term solution to a long‐term problem – a three‐stage plan of action termed the federal plan for the development of national human resources (FPDNHR). FPDNHR suggests more effective ways to reduce unemployment by stimulating economic growth, accumulation of capital, development of skills, increasing productivity, reforming the educational system and providing skills consistent with the demands of the labor market.FindingsAn effective solution for the UAE unemployment quandary is only possible after the three‐step strategy FPDNHR is applied completely.Research limitations/implicationsThe FPDNHRO as suggested in this study is but a conceptual blueprint for a strategy that requires further research and fine‐tuning in order to develop an action plan. Priorities and sequencing must ensure that each element of the strategy is cost‐effective.Practical implicationsUnemployment is a macro‐dilemma and the strategic solution to the unemployment dilemma needs to be based and implemented on a national level through a federally mandated plan; the unemployment program will move in an orderly and strategically top‐down manner.Originality/valueThis paper fulfills an identified information/resources need and offers a long‐term practical solution to a unique macro‐dilemma.
Influences of contextual variables on the intention to use technology in education
Authors: Teo Timothy 
Published: March 2013

PurposeThe purpose of this paper is to examine the influences of selected individual, technological and implementation variables on the intention to use technology, among a sample of primary school teachers in Singapore.Design/methodology/approachIn total, 385 teachers from 18 primary schools completed a survey questionnaire measuring their responses to six constructs that are categorized into in three contexts in which teachers’ intention to use technology was influenced. Latent variable modeling was used as the technique for data analysis.FindingsThe results showed that teachers’ intention to use technology was not significantly influenced by the three contexts. However, each of the three contexts was significantly explained by their variables. The results suggest that the teachers in this study may have conceptualized the influences on their intention to use technology differently than commercial users of technology, as seen from the information sciences literature.Originality/valueThis study contributes to our understanding of what influences the intention to use technology among educational users. While much research has been focused at the variable level, this study examines the contexts in which variables interact with each other.
Achieving age equality in health and social care
Authors: Bernard Caroline 
Published: March 2013

PurposeThe aim of this paper is to provide an overview of the Achieving Age Equality Toolkit, to give the background to its development, and to advise readers of the ways in which it has already been successful in the health and social care arena.Design/methodology/approachThe subject of this paper is the ban on age discrimination in goods and services that came into force on 1 October 2012. The objectives of the paper are achieved by setting out the policy context, and by detailing how the age equality recommendations were made through an independent review.FindingsOlder people have different experiences of health and social care services, but most want to be able to access support when they need it. Age as a barrier to treatment and screening in areas such as mental health and cancer continue to give cause for concern. Organisations need to ensure they are working in an “age equal” way across services.Research limitations/implicationsImplications for further research could include an assessment of the extent of “institutional ageism” in services after the ban on age discrimination in goods and services on 1 October 2012.Practical implicationsThe article illustrates through case studies how use of the toolkit enables one organisation to better identify where changes are needed towards embedding anti age discrimination practice.Social implicationsAs well as obeying legal requirements, ending age discrimination in health and social care requires a change in hearts and minds towards encouraging society to think differently about the ways in which older people are supported by health and social care services.Originality/valueSince the review, there have been repeated cases of age discrimination in goods and services, illustrating the need for change.
Analytical and experimental study on damping ratio of GRP‐reinforced glulam beams
Authors: Naghipour Morteza , Akbar Gholampour Ali , Nematzadeh Mehdi 
Published: March 2013

PurposeThe purpose of this paper is to present weighted residual method (WRM) for evaluating damping ratio of unreinforced glued‐laminated (glulam) wood beams and also reinforced glulam beams with E‐glass reinforced epoxy polymer (GRP) plates.Design/methodology/approachIn this method, created error from the regression curve to the peak points of experimental displacement values is minimized. Several weight functions such as Galerkin weight function, Petrov‐Galerkin weight functions, and least square weight function are used for minimizing this error and results from these methods are compared to the existing methods as; logarithmic decrement analysis (LDA), Hilbert transform analysis (HTA), moving block analysis (MBA), and half power bandwidth (HPB).FindingsBecause WRM tries to minimize the error function provided from differences between theoretical and experimental fitted curves, comparison among these methods indicate that proposed procedure is useful for any range of damping ratios and it gives better values in comparison with the other methods. Due to the initial conditions and weight function used in Galerkin weighted residual method, damping ratio values obtained from this method have different values from the other weighted residual methods. Among the existing methods, HPB method could not predict damping ratio of the glulam beams accurately.Originality/valueThis paper is a high quality research paper that presents weighted residual method (WRM) for evaluating damping ratio of unreinforced glued‐laminated (glulam) wood beams and also reinforced glulam beams with E‐glass reinforced epoxy polymer (GRP) plates. In this paper, LDA, HTA, MBA, and HPB methods are used and an analytical investigation of damping ratios of glulam beams unreinforced and reinforced with GRP plates is proposed by using weighted residual method (WRM). Although there is a simplifier assumption in some of existing methods, proposed method shows the damping ratio can be calculated without any requirement to simplifier assumption.
Employee perceived effects of workplace health promotion
Authors: Nöhammer Elisabeth , Schusterschitz Claudia , Stummer Harald 
Published: March 2013

PurposeThe employees’ perspective is often disregarded in research regarding workplace health promotion (WHP). Experts’ opinions are prominent, stating employees’ benefits of WHP on the physical, mental, and social level. The purpose of this paper is to investigate which benefits and effects employees expect from WHP.Design/methodology/approachAs a current qualitative study indicates that employees also highlight cognitive aspects and prevention issues, a quantitative verification of this extended model was conducted. A questionnaire consisting of items derived from a qualitative study was developed and distributed in Austria in two government agencies, one bank, and one NGO. The sample consists of 237 employees rating the appreciability of potential WHP effects.FindingsBased on a principal component analysis, employee‐perceived effects of WHP were grouped into four components. Within the first, cognitive one, the most frequently perceived effect (40.1 per cent) was giving WHP a try. Regarding the second, emotional component, feeling appreciated (57.4 per cent) was emphasized. Improved affordability of prevention (57.0 per cent) belongs to the third, convenience/pleasure component. Effects in the fourth, social realm, such as better contact with colleagues, were perceived by only 17.4 per cent.Research limitations/implicationsThe results enlarge the theoretical grouping of WHP effects but require further testing regarding blue‐collar employees, and physical benefits.Practical implicationsStrengthening factors referring to perceived benefits in practical WHP design plus related communication seems advisable to increase participation rates and benefits derived.Originality/valueProviding an enlargement to current models of employee perceived benefits regarding WHP, this paper gives suggestions for a benefit oriented WHP program and communication design and opens up new paths for research.
Studies on women's entrepreneurship from Nordic countries and beyond
Authors: Achtenhagen Leona , Tillmar Malin 
Published: March 2013

PurposeThe purpose of this paper is to direct attention to recent research on women's entrepreneurship, focusing on Nordic countries.Design/methodology/approachThe paper encourages research that investigates how context, at the micro, meso and macro level, is related to women's entrepreneurship, and acknowledges that gender is socially constructed.FindingsThis paper finds evidence that recent calls for new directions in women's entrepreneurship research are being followed, specifically with regard to how gender is done and how context is related to women's entrepreneurial activities.Originality/valueThis paper assesses trends in research on women's entrepreneurship, mainly from the Nordic countries.
Networking women entrepreneurs: fruitful for business growth?
Authors: Bogren Maria , von Friedrichs Yvonne , Rennemo Øystein , Widding Øystein 
Published: March 2013

PurposeThe purpose of this paper is to explore the kinds of contacts and networks women find supportive in their role as business leaders, and which also support their willingness to grow their business. The approach is to investigate the context of women entrepreneurs and the kinds of supporting social networks of which they are part. This is seen in relation to their willingness to grow.Design/methodology/approachQuestionnaires were sent to women entrepreneurs in mid‐Sweden and mid‐Norway, relating to supportive assets and willingness for growth.FindingsThe results show: that personal networks are seen as a more supportive asset than business networks; that personal contacts with other entrepreneurs are regarded as valuable; and that women entrepreneurs who are positive towards new networks already have a more heterogenic network than those who do not express this willingness.Practical implicationsWithout a relational attitude and a willingness to put oneself into a relational interplay, women entrepreneurs will have a hard time succeeding in growing their businesses.Originality/valueThis study is unique in three ways: first, it combines different theoretical perspectives, above all a variety of network perspectives seen in an entrepreneurial context. Second, from a huge set of data containing women entrepreneurs, the paper presents valid findings about social network configurations among this group. Third, it introduces the term “willingness”, and discusses the effects related to this and to network expansion and business growth. These dimensions help us to increase the understanding of networking and growth in women‐owned enterprises.
Risk society and the distribution of bads: theorizing class in the risk society
Authors: Curran Dean 
Published: March 2013

AbstractUlrich Beck states in the Risk Society (1992) that the rise of the social production of risks in the risk society signals that class ceases to be of relevance; instead the hierarchical logic of class will be supplanted by the egalitarian logic of the distribution of risks. Several trenchant critiques of Beck's claim have justified the continued relevance of class to contemporary society. While these accounts have emphasized continuity, they have not attempted to chart, as this paper will, how the growing social production of risk increases the importance of class. This paper argues that it is Beck's undifferentiated, catastrophic account of risk that undergirds his rejection of class, and that by inserting an account of risk involving gradations in both damages and calculability into Beck's framework, his theory of risk society may be used to develop a critical theory of class. Such a theory can be used to reveal how wealth differentials associated with class relations actually increase in importance to individuals’ life‐chances in the risk society. With the growing production and distribution of bads, class inequalities gain added significance, since it will be relative wealth differentials that both enables the advantaged to minimize their risk exposure and imposes on others the necessity of facing the intensified risks of the risk society.
The problem of suffering as a driving force of rationalization and social change
Authors: Wilkinson Iain 
Published: March 2013

AbstractThis article documents and analyses a reconstructed Weberian conception of the problem of suffering. In this setting a focus is brought to how the problem of suffering is constituted in the dynamic interplay between, on the one hand, the compulsion to impose rational sense and order on the world, and on the other, the necessity to find a means to satiate charismatic needs. The discussion highlights Weber's account of the tendency for problems of suffering to increase in volume and scale along with the intensification and spread of modern processes of rationalization. It offers a case for the development of further sociological inquiries into the role played by experiences of the problem of suffering within the dynamics of social and cultural change.

Authors: Spracklen CN , Harland KK , Stegmann BJ , Saftlas AF 
Published: March 2013

ObjectiveTo determine whether women with a history of surgery for cervical intraepithelial neoplasia (CIN) are at an increased risk of subfertility, measured as a time to pregnancy of more than 12 months.DesignCase–control study.SettingIowa Health in Pregnancy Study (IHIPS), a population‐based case–control study of preterm and small‐for‐gestational‐age (SGA) live birth outcomes (from May 2002 through June 2005) in the USA.SampleWomen with an intended pregnancy and a history of either one prior cervical surgery (n = 152), colposcopy only (n = 151), or no prior cervical surgery or colposcopy (n = 1021).MethodsCervical treatment history, pregnancy intention, time to pregnancy, and other variables were self‐reported by computer‐assisted telephone interviews. Odds ratios were calculated using logistic regression to estimate the risk of prolonged time to pregnancy among women with a history of cervical surgery or colposcopy alone, compared with untreated women (control group).Main outcome measureProlonged time to pregnancy (i.e. >1 year).ResultsProlonged time to pregnancy was most prevalent among treated women (16.4%), compared with untreated women (8.4%) and women with colposcopy only (8.6%) (P = 0.039). After adjusting for covariates, women with prior cervical surgery had a more than two‐fold higher risk of prolonged time to pregnancy compared with untreated women (aOR 2.09, 95% CI 1.26–3.46). In contrast, women with a history of colposcopy only had a risk equivalent to that found among untreated women (aOR 1.02, 95% CI 0.56–1.89).ConclusionsWomen with a history of cervical treatment for CIN are at increased risk of subfertility, measured as a time to pregnancy of more than 12 months.
Civil society participation in global governance: Insights from climate politics
Authors: Böhmelt Tobias , Koubi Vally , Bernauer Thomas 
Published: March 2013

AbstractA rather unique feature of global climate negotiations is that most governments allow representatives of civil society organisations to be part of their national delegation. It remains unclear, however, why states grant such access in the first place. While there are likely to be benefits from formally including civil society, there are also substantial costs stemming from constraints on sovereignty. In light of this tradeoff, this article argues for a ‘contagion’ effect that explains this phenomenon besides domestic determinants. In particular, states, which are more central to the broader network of global governance, are more likely to be informed of and influenced by other states' actions and policies toward civil society. In turn, more central governments are likely to include civil society actors if other governments do so as well. This argument is tested with data on the participation of civil society organisations in national delegations to global climate negotiations between 1995 and 2005. To further uncover the underlying mechanisms, the article also provides an analysis of survey data collected at the United Nations Framework Convention on Climate Change (UNFCCC) negotiations in Durban in 2011.
Discrepancies in Death Certificates, Public Health Registries, and Judicial Determinations in Italy
Authors: Minelli Natalia , Marchetti Daniela 
Published: March 2013

AbstractThe death certificate is mandated by civil law and serves as a medical‐scientific document useful for biostatistics and epidemiological research. For a variety of reasons, death certificates can be misclassified. We reviewed data from self‐inflicted deaths collected over an 8‐year period by the Forensic Institute of the University Sacro Cuore of Rome (Italy). Four hundred and thirty‐five of 2904 were classified as self‐inflicted deaths (15%). The comparison with death certificates processed by the local public health authority (ASL) and by the Italian National Census Bureau (Istat) and with the judicial investigation results available in the Italian Penal Court archive shows some discrepancies. One‐hundred and twenty‐four of 435 deaths were not considered to be self‐inflicted but due to a crime (29% overrecording suicide) with a higher reduction for women, suggesting that it is easier to confuse a murder for suicide in female cases. Any discrepancies between the mortality and crime data are discussed in details.
