Localization and tracking algorithm for mobile robot based on wireless sensor network
Authors: Zhen Liu , Mingli Ding , Qi Wang 
Published: July 2010

PurposeThe purpose of this paper is to describe a low‐cost mobile robot localization and navigation system based on wireless sensor network (WSN). This can be used in extreme environments such as mines, hostile areas, and other places where static nodes cannot be deployed directly.Design/methodology/approachThe distance between robot and beacon nodes is estimated by received signal strength indicator (RSSI). The adaptive Kalman filter algorithm is used to eliminate noise from the RSSI signal. Then, the paper gets the mobile robot's status information which includes position, velocity, and acceleration. In order to improve the real‐time performance of systems and reduce the computation overhead of robot's CPU, the paper chooses a beacon node by some certain rules to implement the localization program. The robot and beacon nodes use the CC2430 as the communication and data‐processing unit.FindingsThe experiment shows it has the characteristics of good position precision, is easily realized, and inexpensive.Research limitations/implicationsThat the system needs so many beacon nodes, is the main limitation.Practical implicationsA very useful and low‐cost method for mobile robot localization and navigation.Originality/valueThe innovative aspect of the paper is that it attempts an analysis of the localization system based on WSN, by attempting to analyze and explain the model of localization system which includes robot and beacon nodes.
Employee‐organization relationship in collective entrepreneurship: an overview
Authors: Ribeiro‐Soriano Domingo , Urbano David 
Published: July 2010

PurposeThe purpose of this paper is to add new theoretical insights on the employee‐organization relationship (EOR) in the context of corporate entrepreneurship (CE), specifically in collective entrepreneurship.Design/methodology/approachThe paper presents a brief overview of the content of each of the articles included in this special issue.FindingsIn the last decades, the study of the EOR has become an integral part of the literature as an approach aimed to provide the theoretical foundations to understanding the employee and employer perspectives to the exchange. Also, the greater complex environment and the higher level of innovativeness have pushed firms to become more entrepreneurial in order to identify new opportunities for sustained superior performance. In this context, emerges CE and involves not only formal activities to enhance product innovation, risk taking and a proactive response to environmental forces, but also organizational learning, driven by collaboration, and commitment. Specifically, different EORs and specific human resources management practices are required in the light of collective entrepreneurship, understood as work among entrepreneurial teams within the organizations and collaboration among employees.Originality/valueThe paper provides an overview of the EOR in collective entrepreneurship.
Innovative capability development for entrepreneurship
Authors: Annique Un C. , Montoro‐Sanchez Angeles 
Published: July 2010

PurposeThe purpose of this paper is to integrate three streams of literature – organizational capabilities based in resource‐based view (RBV) and the team‐ and organization‐level innovation – to provide a theoretical framework of how firms invest in developing innovative capabilities for entrepreneurship and change management.Design/methodology/approachThis is a conceptual paper based on the RBV and the team‐ and organization‐level innovation literatures.FindingsLinking the three bodies of literature, two main models for developing innovative capabilities are proposed: organization and project team models. The “organization model” requires firms to invest at the organization level to generate the supporting organization‐level processes, i.e. communication routines, independent of when they organize for innovation, and the “project team model” calls for just‐in‐time investment as needed in the process of innovation. The paper discusses other potential models and provides directions for future research on this important and timely topic.Originality/valueThe paper expands the RBV of the firm by providing a theoretical framework of how firms develop the capabilities to mobilize and create knowledge for innovation as an entrepreneurial activity and for managing the changes in organizations.
The relative importance of service features in explaining customer satisfaction
Authors: Pantouvakis Angelos 
Published: July 2010

PurposeThe purpose of this paper is to assess the relative importance of various service‐quality dimensions in explaining customer satisfaction; and to examine whether this assessment is affected by the measurement instrument that is used.Design/methodology/approachA new (“servicescape”) model for directly measuring the physical and the interactive features of a service is proposed and tested against the SERVQUAL measurement model and Nordic conceptualisation. Data are collected from a structured questionnaire survey of 434 passengers at the port of Piraeus in Greece.FindingsThe findings reveal that the widely used SERVQUAL instrument fails to fully capture the role of “tangibles” in determining overall customer satisfaction in the service under examination. The new proposed “servicescape model” attaches more importance to the role of physical environmental attributes than has been reported in most previous studies.Practical implicationsService providers should pay more attention to the physical environment in which they are operating. They should also note that different measurement instruments provide different results.Originality/valueThis paper proposes and tests a new (“servicescape”) measuring instrument that has not been previously developed or operationalised.
Development of personalised services in small business: an iterative learning process
Authors: Gottfridsson Patrik 
Published: July 2010

PurposeThe aim of this study is to achieve a better understanding of how small business develops personalised business‐to‐business services.Design/methodology/approachIn‐depth interviews are conducted with representatives of 11 small Swedish companies in the service sector. Qualitative data from the interviews are coded and sorted according to themes.FindingsService development in the firms studied is an unstructured, incremental, and relatively informal process that proceeds as part of the firms' day‐to‐day interactions with their customers. It is essentially an iterative learning process by which individuals develop new knowledge and competencies to enhance the capacity of their firms to solve the specific problems of customers.Originality/valueIn contrast to the highly structured and sequenced models that have characterised most of the existing research on service development, this study provides an alternative view of new service development as a relatively informal learning process.
A review and future research directions of secure and trustworthy mobile agent‐based e‐marketplace systems
Authors: Patel Ahmed , Qi Wei , Wills Christopher 
Published: July 2010

PurposeThere is a need to provide secure and safe information security systems through the use of firewalls, intrusion detection and prevention systems, encryption, authentication, and other hardware and software solutions. The purpose of this paper is therefore to propose a framework which includes safe, secure, trusted, and auditable services, as well as forensic mechanisms to provide audit trails for digital evidence of transactions and protection against malicious and illegal activities.Design/methodology/approachThe paper reviews the literature as the foundation and knowledge base for the proposed framework and system of secure and trustworthy mobile agent (MA)‐based e‐marketplaces. It consists of the current state of the art taxonomy for the classified MA‐based frameworks for e‐marketplace trading, underlying supporting systems, e‐payment systems, and the essential issues related to auditable and digital forensic services.FindingsThe current knowledge shows that there is a serious lack of auditable and digital forensic services to make secure and trustworthy MA‐based e‐marketplaces systems. The paper draws conclusions and highlights further research work which is ongoing and new work that needs to be performed.Originality/valueThe paper perceives the needs to define the requirements for secure and trustworthy MA‐based e‐marketplaces and proposes a framework to design effective systems using the latest techniques and technologies.
The use of feedback in lab energy conservation: fume hoods at MIT
Authors: Wesolowski Daniel , Olivetti Elsa , Graham Amanda , Lanou Steve , Cooper Peter , Doughty Jim , Wilk Rich , Glicksman Leon 
Published: July 2010

PurposeThe purpose of this paper is to report on the results of an Massachusetts Institute of Technology Chemistry Department campaign to reduce energy consumption in chemical fume hoods. Hood use feedback to lab users is a crucial component of this campaign.Design/methodology/approachSash position sensor data on variable air volume fume hoods are remotely collected. A 15 minutes average fume hood sash positions for each laboratory are recorded. Data are compiled monthly and a report with average sash position over time and relative frequency of hood position are delivered to the principal investigators of the labs.FindingsAverage sash height is lowered by 26 percent (from 16.3±0.85 percent open to 12.1±0.39 percent open) throughout the department, saving an estimated $41,000/year. Sash position during inactive periods is lowered from 9 to 6 percent open. Half of all department savings occurred in four (of 25) labs. Energy savings are substantially less than original expectations because most installed fume hoods use combination sashes. Labs with vertical sashes use the most energy, and see the most savings from the intervention.Practical implicationsMonthly feedback is an effective tool for encouraging better hood use behavior. Potential savings from even large behavior changes can be limited if existing equipment is relatively efficient, so conservation programs should be tailored to the existing conditions.Originality/valueThe present analysis provides data on the impact of a program in a relatively efficient setting compared to other fume hood conservation reports. The results have cautionary value for designers of similar programs. A breakdown of a laboratory building utility use is also provided.
Using visualization technologies for design and planning of a healthy construction workplace
Authors: Rwamamara Romuald , Norberg Håkan , Olofsson Thomas , Lagerqvist Ove 
Published: July 2010

PurposeThe purpose of the paper is to investigate how health and safety gains and improvements of the construction workplace can be made through the use of three‐dimensional (3D) and four‐dimensional (4D) visualization technologies.Design/methodology/approachThe methodology used in the paper was a combination of semi‐structured interviews with five construction project planners from three construction projects and observations of a 4D model used in one of the three projects.FindingsThe findings of the paper have shown a great potential for 3D and 4D visualization in terms of communicating construction information as well as the health and safety risks in the design process where clash detection, work tasks sequence, workspace congestion can be identified by project stakeholders who are thus able to plan for alternative solutions to reduce or eliminate rework, heavy material handling and repetitive and awkward postures which expose workers to musculoskeletal injury risk.Research limitations/implicationsThe 3D and 4D models as they are currently used in the design of construction projects, particularly in the three projects investigated in this paper, still lack the worker reference frame and the visual interaction between the worker and the permanent as well as the temporary works.Originality/valueThe paper describes the current and emerging trends in the development of 3D, virtual reality and 4D computer‐aided design visualization and simulation, which have affected or are likely to have an impact on construction projects planning in the Swedish construction sector.
Interface research: a commentary on a commentary – ten years on
Authors: Carson David 
Published: July 2010

PurposeThis paper aims to be a reflection on the marketing/entrepreneurship interface paradigm after ten years.Design/methodology/approachThe paper reviews original comments made in the inaugural issue Journal of Research in Marketing and Entrepreneurship and uses relevant parts of this to serve as a foundation for contemporary reflections.FindingsThe paper finds that perhaps there is a need to refocus research initiatives towards small business (SB) marketing/entrepreneurship.Practical implicationsGiven the dearth of knowledge within the small business sector of WEB and WEB 2.0 as potential business tools, there are potentially huge practical implications stemming from meaningful research outcomes.Originality/valueComments are original thought based on many years' research and practice in the SB marketing/entrepreneurship interface.
A note on capital structure target adjustment – Indonesian evidence
Authors: Reinhard Ludwig , Li Steven 
Published: July 2010

PurposeThe purpose of this paper is to investigate whether existing capital structure target adjustment models are able to identify whether companies adjust their capital structures towards an (unobservable) target.Design/methodology/approachExisting capital structure target adjustment models are applied to a specific dataset by using different regression techniques (ordinary least square, fixed effect, Fama‐MacBeth, least square dummy variable “corrected”, SYS‐GMM).FindingsExisting capital structure target adjustment models are not able to identify whether companies adjust their capital structures towards a target or not. They might indeed indicate target adjustment behaviour when companies' capital structures actually move away from their targets.Research limitations/implicationsAs target adjustment behaviour is often used as support for the trade‐off and against the pecking order theory, the “horse race” between both theories seems still to be open.Originality/valueThis paper highlights some of the fallacies of existing capital structure target adjustment models and demonstrates that the results obtained by those models can be highly misleading.
The ultimate client experience: recipe for success in a down (or any) economy
Authors: Pope Michelle 
Published: July 2010

AbstractThe purpose of paper is to give recommendations to find the perfect recipe to delivering a client experience like no other.Design/methodology/approachThe author's approach to this article was to not only research how others were providing an experience to their clients but to also interview existing and potential clients as to what they believe to be a great experience and how they might be accomplishing providing that experience to their clients in their businesses.FindingsEach experience may be unique; however, the key is for it to be consistently delivered regardless of who the client is interfacing with within your organization. Your employees at all levels must understand what the experience looks like and how to deliver upon it each and every time they interface with a client.Originality/valueThere is not necessarily anything new to the approach of creating the client experience – just validation as to how you can go about doing so.
Sourcing, insourcing and two times outsourcing: four phases of procurement of telecommunications services within the Swedish public sector
Authors: Brege Staffan , Brehmer Per‐Olof , Lindskog Helena 
Published: July 2010

PurposeThe purpose of this paper is to describe and analyze how and why the question of outsourcing or insourcing within a specific empirical context, telecommunications services, has been handled differently over time.Design/methodology/approachA longitudinal study on procurement of telecommunications for the Swedish public sector's organizations during the last 40 years. The empirical data were collected from three case studies and one research project.FindingsThe paper identifies four phases: from a simple buying situations, via insourcing of equipment in order to produce some services in‐house, to outsourcing of telecommunications in a first step and to outsourcing of combined data and telecommunications in a second step. Three major contextual determinants are identified for the public procurement of telecommunications services: de‐monopolization, rapid technical development and pressure on public agencies from politicians, citizens and others. In addition to low cost, core competence, control and flexibility, the paper identifies business development as a new logic for outsourcing and insourcing.Research limitations/implicationsThis study is limited to Sweden and public procurement of telecommunications services. Therefore, it would be of value to test if the development of public procurement of telecommunications in other countries passed through the same phases and with the same determinants.Practical implicationsMany of the findings are valid for public procurement in other countries, especially in the European Union due to the common legislative base for public procurement.Originality/valueThe paper fulfills an identified need to carry out a longitudinal study of changes in public procurement of telecommunications through the different phases of in/outsourcing.
How gendered is organizational commitment? The case of academic faculty
Authors: Fisher Ron , Boyle Maree V. , Fulop Liz 
Published: July 2010

PurposeThe purpose of this paper is to investigate the gendered and emotionalized nature of organizational commitment in a university context.Design/methodology/approachThe paper presents a qualitative study that utilizes a grounded theory approach. The research investigates the gendered and emotionalized nature of commitment which is often not accurately and clearly understood in the context of the modern workplace.FindingsThe research finds that the existing measures of organizational commitment are biased and are not appropriate measures of the commitment of women and some men in contemporary workplaces. Studying organizational commitment using an interpretive approach allows a more realistic picture to emerge.Practical implicationsCurrent approaches focus on measurement rather than understanding the nature of organizational commitment. As a consequence, the commitment of women, and some men, is not accurately and clearly understood in many workplaces. Lack of understanding leads to the perception that women, and some men, are lacking in commitment to their organizations. Many management decisions, such as promotion and performance management, are based on the perceptions that managers have of subordinates' commitment to the organization.Originality/valueFew researches have been conducted into how organizational commitment is understood from the perspective of the employees themselves. This paper provides insight into how managers can make more appropriate decisions based on a clearer understanding of commitment.
A systematic review of the effectiveness of smoking relapse prevention interventions for abstinent smokers
Authors: Agboola Shade , McNeill Ann , Coleman Tim , Leonardi Bee Jo 
Published: July 2010

ABSTRACTAims  To carry out a systematic review of the effectiveness of relapse prevention interventions (RPIs) among abstinent smokers who had completed an initial course of treatment or who had abstained unassisted, pooling only outcome data from similar follow‐up time points.Methods  We used the same search strategy as was used in Cochrane reviews of RPIs to identify randomized trials of behavioural and pharmacological studies of smoking RPIs published up to July 2008. Abstinence from smoking was defined as either continuous abstinence or point prevalence abstinence, measured at three follow‐up time points: short term (1–3 months post randomization), medium term (6–9 months) and long term (12–18 months). Abstinence among pregnant/postpartum women was also measured at delivery or the last follow‐up prior to delivery. Random effect meta‐analysis was used to estimate pooled odds ratios (OR) with 95% confidence intervals (CI).Results  Thirty‐six studies randomizing abstainers were included. Self‐help materials appeared to be effective in preventing relapse at long‐term follow up in initially unaided quitters (pooled OR 1.52; 95% CI 1.15 to 2.01, I2 = 0%, NNT = 11, 3 studies). Other behavioural interventions for relapse prevention appeared effective in the short term only. There were positive results for the use of pharmacotherapies for relapse prevention. Bupropion was effective at long‐term follow‐up (pooled OR 1.49; 95% CI 1.10 to 2.01; I2 = 0%; NNT = 11; 4 studies). Nicotine replacement therapy (NRT) was effective at medium‐term (pooled OR 1.56; 95% CI 1.16 to 2.11; I2 = 37%; NNT = 14; 4 trials) and long‐term follow‐ups (pooled OR 1.33; 95% CI 1.08 to 1.63; I2 = 0%; NNT = 20; 4 trials). Single trials of extended treatment of Varenicline and rimonabant were also found to be effective at short‐term and medium‐term follow‐ups.Conclusions  Self‐help materials appear to prevent relapse in initially unaided quitters. Use of NRT, bupropion and varenicline appears to be effective in preventing relapse following an initial period of abstinence or an acute treatment episode. There is currently no good evidence that behavioural support prevents relapse after initial unaided abstinence or following an acute treatment period.

Published: July 2010

ABSTRACTAims  To analyse whether changes in maintenance treatment of opiate‐dependent subjects in Sweden were related to changes in opiate‐related mortality and inpatient care from 1998 to 2006.Design  We collected data from surveys of methadone maintenance treatment units, of buprenorphine and methadone sales, and of mortality and inpatient care in Sweden.Setting  Sweden.Participants  Patients in maintenance treatment.Measurements  Survey data of treatment policy to all units in 2003 and 2005. Trend tests and correlation analyses of data on sales, mortality, inpatient care and forensic investigations.Findings  The surveys showed a marked change to a less restrictive policy, with increased use of ‘take‐away doses’ and a reduction of discharges due to side misuse. The one‐year retention rate stayed high. Sales of buprenorphine and methadone and the number of patients in treatment increased more than threefold from 2000 to 2006, with the greatest increase for buprenoprphine, introduced in year 2000. There was a significant 20–30% reduction in opiate‐related mortality and inpatient care between 2000–2002 and 2004–2006 but not of other drug‐related mortality and inpatient care. This decline was larger in Stockholm County, which had a less restricted treatment policy. However, a significant increase in buprenorphine‐ and methadone‐related mortality occurred. For the study period 1998–2006, statistically significant declines occurred only in Stockholm County.Conclusions  The liberalization of Sweden's drug policy correlated with an increase in maintenance treatment, a decrease in opiate‐related mortality and inpatient care and an increase in deaths with methadone and buprenorphine in the tissues.
