Authors: Zusevics Kaija L. , Lemke Melissa A. , Harley Amy E. , Florsheim Paul 
Published: April 2013

PurposeMilwaukee has very high rates of risky sexual behavior and low rates of academic achievement among adolescents. Milwaukee school representatives partnered with researchers to create and implement an innovative project‐based learning (PBL) high school health curriculum to engage students in school. This health education program, Project Health (PH), aimed to engage Milwaukee Public Schools high school students, by PBL, into the urban health classroom. The purpose of this paper is to examine the impact of the curriculum on student engagement and document the process of implementing this program, in order to identify strengths, weaknesses and areas of needed improvement.Design/methodology/approachStudent engagement was measured with an 18‐item scale at three time points in intervention and control schools. Attendance data were collected by tracking the number of days students were absent from school the semester the curriculum was implemented. Analysis of covariance was used to test whether students in PH classes were more engaged and if they had fewer absences than students in the control classes. The process evaluation included interviews with teachers, focus groups with high school students, and focus groups with teaching assistants. Interviews were transcribed and analyzed using thematic analysis to extract key themes and categories across all data.FindingsStudents in the intervention health class were significantly less absent from school than control students. However, they were not more engaged than their peers in control schools as measured by a student engagement scale. Various components of the PBL teaching approach used in the Project Health high school curriculum were viewed as positive by health educators, students, and teaching assistants. Results indicate that PBL used in health education may increase school attendance.Originality/valueThis study was original in that it documented how a novel health education program that incorporated PBL can positively impact urban students’ school attendance. It also highlighted the process of implementing this program from the vantage point of students, assistants, and health education.
Workplace conflict and employee well‐being
Authors: Sonnentag Sabine , Unger Dana , Nägel Inga J. 
Published: April 2013

PurposeThe purpose of this study is to address the relation between task and relationship conflicts at work and employee well‐being. It seeks to examine psychological detachment from work during off‐job time as a moderator in the relation between conflicts and well‐being.Design/methodology/approachIn a field study, 291 white‐collar employees completed survey measures of task conflicts, relationship conflicts, psychological detachment from work during off‐job time, and well‐being. Control variables included workload and job control.FindingsHierarchical regression analyses indicated that employees experiencing high levels of task conflicts and high levels of relationship conflicts report poorer well‐being. As predicted, psychological detachment from work mitigated the negative relation between relationship conflicts and well‐being. Contrary to expectations, psychological detachment failed to moderate the relation between task conflicts and well‐being.Practical implicationsThe study suggests that employees should be encouraged to disengage mentally from work during leisure time.Originality/valueThis study links research on workplace conflicts with research on recovery processes. It tests the moderator effect of psychological detachment from work on the association between workplace conflicts and well‐being.
Optimization of positioning system of FDM machine design using analytical approach
Authors: Wesley Machado Cunico Marlon , de Carvalho Jonas 
Published: April 2013

PurposeThe purpose of this paper is to analyse the conception of the positioning system of fused deposition modeling (FDM) machines, optimising design parameter and components accuracy to decrease mechanical errors of equipment, which, consequently, results in the increase of parts accuracy. This paper also reports studies related to analytical estimation of machine errors, describing a theoretical model which was used for the multivariable study. Additionally, an alternative conception is proposed, according with the result of this study.Design/methodology/approachFor elaboration of the numerical model of equipment, the authors have focused on conception of first generation of FDM, specifying as design parameters, timing belt stiffness, linear bearing clearance, and accuracy grade of ball screw housing, support and pulley. In order to identify the main effect of each design parameter for the final error of machine, the authors have applied a multivariable method in addition to identifying the error budget of model. Also indicated are the two factors that promote more errors, undergoing a proposal of conception which consists in replacing one component of machine.FindingsWith reference to the evaluation of the numerical model, equivalency was found between the resultant error of model and the current FDM accuracy. The result of multivariable study identified the main causes of errors in machine, implying on an optimized solution which decreases the initial error in 69 μm. Similarly, the evaluation of the proposed conception resulted in the reduction of general error in almost 20 μm, even though the worst case was studied for this comparison.Originality/valueAlthough the number of applications for additive manufacturing has been growing in recent years, implying an increase of demand for high precision parts, there are still several challenges to be overcome, such as the improvement of equipment. For that reason, the motivation of this work concerns the contribution for development of new equipment, as well the improvement of current technologies. Furthermore, the authors' focus was the reduction of mechanical errors through an analytical approach.
Comparison of different post processing technologies for SLM generated 316l steel parts
Authors: Löber Lukas , Flache Christoph , Petters Romy , Kühn Uta , Eckert Jürgen 
Published: April 2013

PurposeThe purpose of this paper is to compare different post processing techniques for improving the high surface roughness (SR) characteristic of parts generated by selected laser melting (SLM).Design/methodology/approachTest parts were built by SLM and their surface was characterized via SEM and optical measurements. The surface of the as‐generated parts was then modified by grinding, sand blasting and electrolytic and plasma polishing to reduce the SR.FindingsThe change of the SR after the different surface treatments was quantified and compared. The effectiveness and usability of the post processing techniques and their combinations were determined. The results indicate that some of the post processes are only usable for simple structures.Research limitations/implicationsThe amount of abrasion induced by the different surface treatments was not quantified. A major focus of future work should deal with this issue.Practical implicationsThe surface quality of parts with simple geometry can be enhanced by simple methods such as grinding. Complex parts need more advanced techniques, such as electrolytic polishing.Originality/valueThe effect of different post processing techniques for improving the surface roughness of SLM‐generated parts has been analyzed for the first time. This paper can help to improve the SR of parts produced by SLM.
An integrated cost‐model for selective laser melting (SLM)
Authors: Rickenbacher L. , Spierings A. , Wegener K. 
Published: April 2013

PurposeThe integration of additive manufacturing (AM) processes into a production environment requires a cost‐model that allows the precise estimation of the total cost per part, although the part might be produced in the same build job together with other parts of different sizes, complexities and quantities. Several cost‐models have been proposed in the past, but most of them are not able to calculate the costs for each single part in a mixed build job or are not suitable for Selective Laser Melting (SLM). The purpose of this paper is to develop a cost model, including all pre‐ and post‐processing steps linked to SLM.Design/methodology/approachBased on collected data and the generic cost model of Alexander et al., an adapted model was developed for the SLM process including all required pre‐ and post‐processes. Each process was analysed and modelled in detail, allowing an evaluation of the influences of the different geometries on the cost of each part.FindingsBy simultaneously building up multiple parts, the manufacturing as well as the set‐up time and therefore the total cost per part can be significantly reduced. In the presented case study a cost reduction of 41 per cent can be achieved in average.Originality/valueUsing different cost allocation algorithms, the developed cost model enables a precise determination of total cost per part avoiding that any geometry is preferred in simultaneous manufacture. This helps to optimize build jobs and to manufacture SLM parts more economically by pooling parts from different projects, whereas the cost per part can still be precisely determined.
An approach to quantifying social justice in selected developing countries
Authors: Helmy Heba E. 
Published: April 2013

PurposeThe objective of this paper is to prove that any attempt to implement social justice in its present undefined form is unattainable, and to successfully achieve social justice, the term should be quantified by an appropriate index; accordingly, the first objective of this paper is to make an attempt to construct an appropriate social justice index. The second objective is to quantify this index for a number of developing countries so that a government with low value of social justice index can make policy for achieving an appropriate level of social justice.Design/methodology/approachThe paper constructs a new composite index for social justice for 40 mostly developing countries by selecting six subindicators, each of which represents one aspect or dimension of social justice. The values of the subindicators are then normalized and the final composite index is formed from the weighted average of the subindicators.FindingsThe study quantified the levels of social justice in developing countries through a new social justice index and compared the ranking of some developing countries using the new index. The index also helped in identifying areas of social justice that need improvement and hence can improve the developing countries' scores in the social justice index.Originality/valueThe paper is valuable to policy makers in developing countries especially the Arab Spring countries in their pursuit for achieving social justice. Quantifying social justice clarifies exactly where such countries stand and the dimensions of social justice that need urgent action to improve their performance and thus their index scores.
Behaviour change strategies for energy efficiency in owner‐occupied housing
Authors: Bichard Erik , Thurairajah Nirooja 
Published: April 2013

PurposeGovernment policies in many countries are trying to accelerate conservation of energy as part of wider carbon management or energy security strategies. This paper aims to describe a trial that tested a behaviour change strategy that combined three different influencing components designed to motivate home owners to invest in energy‐saving measures in the UK.Design/methodology/approachThe research design was based on the findings from an earlier phase of the project and was further supported with a comprehensive literature review. Data collection was carried out using survey strategies, interviews and capturing the actions of the participating households. Data analysis was undertaken using descriptive statistical methods and the most appropriate software.FindingsThe project results reflected that a combination of information delivered at key moments in the decision‐making process, incentives, and norm‐based influences have the potential to help motivate owners of domestic property to invest in energy‐saving measures. However, this strategy needs to be delivered within the context of affordable materials and installer costs.Research limitations/implicationsThe trial was designed to be a limited sample experiment that was commissioned as a proof of concept study. However, policy‐makers may require a larger sample and an extended period before the proposals are rolled out on a national scale.Originality/valueAlthough there are many behaviour change studies, there are far fewer on pro‐environmental behaviour in relation to climate change. This study places an emphasis on non‐cash incentives as the central proposition and this cannot be found within the relevant knowledge domain. The trial was also original in the way it incorporated other influencers including norm‐based tactics and facilitation in a combined strategy with incentives.

The intention was to motivate, invigorate and inspire those employees to be the best that they could be,Design/methodology/approachResults‐driven learning and development agency NKD Learning created a breakthrough training program designed to invigorate employee engagement, instill a truly customer‐centric mindset and deliver measurable success to international company, DHL Express. The blended learning approach of the bespoke Certified International Specialist (CIS) Foundation Program included a one and a half day experiential event, supported by stand‐alone, hour‐long interactive training modules and painstakingly crafted trainer scripts – which could be easily adapted and translated into 42 languages and still be effective.FindingsIn less than 18 months, all 100,000 DHL Express employees had been through the CIS Foundation and all project deliverables had been achieved to agreed quality, cost and timeline standards. End of program feedback scores averaged 5.8 out of 6. Key employee opinion scores significantly exceeded the agreed targets for Strategy, Employee Engagement, and Learning & Development. The actual scores showed year‐on‐year increases of between 7 and 11 percent, compared to the 1 to 3 percent target increases.Originality/valueThe DHL Express CIS Foundation module course incorporates innovative learning methodologies and approaches, cutting‐edge film and animation support messaging, and hi‐impact learning materials.
The decision to trust boosts performance
Authors: Kervinen Anni 
Published: April 2013

PurposeFuturice is an international software design and development house that has grown from three to 150 people in 12 years. In the middle of the growth, people who earlier made perfectly rational and clever decisions independently started suddenly to make bad and unjustifiable decisions. The purpose of this paper is to examine the company strategy to improve decision making and overall performance.Design/methodology/approachThe paper looks at how the company responded by making all company information completely transparent to all its staff. All employees were recommended to make decisions concerning themselves and the work environment. Futurice became very active in fostering a sense of caring. The company also started actively to develop company strategy, vision, mission and short‐term goals with its employees.FindingsThe paper reveals that the chosen way has been successful. Futurice has been growing quickly in all its European offices and yet it is very profitable. People rarely leave the organization and customer satisfaction is also high.Originality/valueThis case study gives HR professionals looking to improve employee decision making an example of a successful strategy.
Chinese multinationals in Denmark
Authors: Li‐Ying Jason , Stucchi Tamara , Visholm Anne , Solvig Jansen Joanna 
Published: April 2013

PurposeThe purpose of this paper is to explain in detail the strategic asset‐seeking OFDIs of Chinese firms in Denmark through a theoretical lens that combines the updated OLI (Ownership, Location, Internalization) paradigm and the internalization theory. Meanwhile, the authors hope to unveil the unique characteristics of firm specific advantages (FSAs, including O and I advantages) and country specific advantages (CSAs, including L advantages).Design/methodology/approachThe authors chose two case firms that just started investing and a third one that was in the process of preparing investment in Denmark. Primary data were collected by semi‐structured interviews in English at various locations in late 2009 and early 2010. The three Chinese firms in this study share a common primary objective in their strategic orientation of OFDIs. That is to seek strategic assets that are complementary and critical to augment their existing FSAs.FindingsRugman stated that strategic asset‐seeking OFDIs are supposed to have high levels of FSAs and CSAs. This study presents a more detailed analysis regarding the O, L and I advantages that Chinese investing firms in Denmark are perceived to possess. It was found that these Chinese investing firms had high levels of Oa and Oi but Ot was largely absent; furthermore, although Lr was obviously appreciated in Denmark, Li presented a mixed picture. The paper also found that internalization advantages were only able to be realized when investing firms were good at utilizing networking and guanxi, which were largely derived from their prior Oi advantages.Originality/valueFew have analyzed strategic asset‐seeking OFDIs made by emerging markets based on the FSA/CSA matrix that combines the OLI paradigm and the internalization theory. This study pursued this research endeavor by enriching a refined framework that connects the OLI paradigm, which recognizes multiple dimensions of O advantages and an institutional perspective, to the internalization theory, which converts O and I advantages into FSAs and associates L advantages with CSAs.
Temporary project network and innovation: research on the Italian regional wine industry
Authors: Pezzillo Iacono Mario , Esposito Vincenza , Berni Alessia 
Published: April 2013

PurposeThis study aims at exploring the characteristics of the Temporary Project Networks (TPNs) in small and medium‐sized wine producing enterprises, both from a theoretical and an empirical perspective. It aims to discuss different types of temporary inter‐firm collaboration clusters both in terms of structural/organizational features and in terms of innovation tasks development. It also aims to develop an empirically derived taxonomy of TPNs within the Sannio wine industry.Design/methodology/approachThe paper focuses on the literature supporting the argument that the act of innovating is related strongly with the creation of new knowledge. In particular, the knowledge‐based theory places primary emphasis on inter‐organizational knowledge exchanges in explaining enhanced knowledge creation toward better innovative outcomes. The design of forms of coordination between companies is investigated with reference to TPNs, a form of collaboration that has been less investigated in the literature, especially with respect to small to medium‐sized enterprises (SMEs). The survey concerned 40 SMEs operating in wine production in Sannio, one of the most promising areas of the Campania region and the entire Italian economic system. The research is based on the use of different quantitative instruments (administration of structured questionnaires and statistical analysis) and qualitative instruments (semi‐structured interviews of management, analysis of information material, reports as well as planning documents of the companies involved in the analysis). A cluster analysis has been carried out to identify TPN typologies.FindingsThe study finds that the different kinds of inter‐organizational collaborations lead to two‐cluster solutions that refer to two of the TPNs models formalised by Bakkeret al.The findings add to the view that there is variation in types of project network and go against the often held idea that temporary projects are by definition short‐termed and focused on non‐routine tasks.Originality/valueThe study was able to expand the understanding of TPNs and innovation in two respects. First, it should be noted that only a few studies have adopted the TPN framework to investigate the inter‐organizational coordination mechanisms among SMEs. This study could usefully find its place in this literature gap, thus contributing to develop a typological research in order to identify TPN clusters with homogeneous distinctive characteristics. Secondly, the study has an explorative role of analysis, which can be useful for generating research hypotheses in future works, connecting the features of TPNs with the development of innovation processes.

Published: April 2013

PurposeKnowledge creation is increasingly singled out as an important activity in a wide range of sectors. At the same time, projects are considered to be thelociwhere much of knowledge creation takes place. The aim of this paper is to give an overview of the current issues within this area and point out a few directions for future research.Design/methodology/approachThis paper is based on a literature review and a summary of the papers included in the special issue. The aim of the literature review consists in pointing out the key themes in the continuing debate on knowledge creation in projects.FindingsThe paper argues that research needs to be developed along the following lines: the preconditions of effective knowledge creation mechanisms; the organizational practices able to support knowledge creation mechanisms; the contribution of communities of practice to knowledge creation in projects; the role of time and timing in projects knowledge creation; and the challenges associated with inter‐organizational projects and knowledge creation.Originality/valueThis paper (and the special issue) provides an understanding of the context of knowledge creation, of the requirements that different contexts place on knowledge creation, and of the suitability of such mechanisms in peculiar contexts. These issues have received only limited attention to date in the project management literature.
