Asynchronous failed sensor node detection method for sensor networks
Authors: Sakib Kazi 
Published: October 2011

SUMMARYDetecting failed nodes is important in a sensor network, because a failed node can cause coverage and connectivity holes. Since sensors are resource‐limited devices, lack of a clocking mechanism imposes difficulties in implementing synchronous failure detection techniques. To counter this, asynchronous methods are needed for detecting failed sensor nodes. For example, in traditional distributed systems sent data packets and received acknowledgements are matched to identify any malfunctions. A similar approach can be adopted in sensor networks. An asynchronous failed sensor node detection (AFSD) method is proposed, where a numeric counter variable is used to track the received and sent data packets between active nodes. This variable acts as bounded for an active sensor node and unbounded for an out‐of‐communication or failed node. By observing the value of the counter, a decision can be made on a deployed sensor node. Whenever the counter value of a neighbour crosses a predefined threshold, that neighbour is suspected. However, measuring a counter value can always lead to a false positive. To avoid false suspicion, a consensus protocol is needed. Such a technique is described, which is proved as accurate and complete. The complexity analysis shows that the control, energy, and time overheads of the proposed method are linear and in the order of number of neighbours per node.

How middle managers' group‐focus emotions and social identities influence strategy implementation
Authors: Huy Quy Nguyen 
Published: October 2011

AbstractThe literature on top‐down strategy implementation has overlooked social‐emotional factors. The results of a three‐year field study of a large technology firm show how top executives who favor an affect neutral task approach can inadvertently activate middle managers' organization‐related social identities, such as length of time working for the company (newcomers versus veterans) and language spoken by senior executives (English versus French), generating group‐focus emotions. These emotions prompt middle managers—even those elevated to powerful positions by top executives—to support or covertly dismiss a particular strategic initiative even when their immediate personal interests are not directly under threat. This study contributes to the strategy implementation literature by linking senior executives' actions and middle managers' social identities, group‐focus emotions, and resulting behaviors to strategy implementation outcomes.

ROME4EU – A service‐oriented process‐aware information system for mobile devices
Authors: Russo Alessandro , Mecella Massimo , de Leoni Massimiliano 
Published: October 2011

SUMMARYNowadays, process‐aware information systems (PAISs) are widely used for the management of ‘administrative’ processes characterized by clear and well‐defined structures. Besides those scenarios, PAISs can be used also in mobile and pervasive scenarios, where process participants can be only equipped with smart devices, such as personal digital assistants. None of existing PAISs can be entirely deployed on smart devices, making unfeasible its usage in highly mobile scenarios. This paper presents ROME4EU, a mobile PAIS developed for being applied to the coordination of emergency operators, and an extensive validation of the system, both in term of performances and usability/acceptability by the users.

Published: October 2011

AbstractThe choice of solvent (alcohol or hydrocarbon), oxidising agent (air, pure oxygen or hydrogen peroxide), and temperature (ambient to boiling solution) is significant in the oxidation of Co(thd)2 [(thd)– = anion of H(thd) = C11H20O2 = 2,2,6,6‐tetramethylheptane‐3,5‐dione]. With EtOH as solvent, refluxing conditions, and oxygen atmosphere the solid reaction product was established as a 2:1 stoichiometric mixture of Co(thd)3 and Co3(thd)3(EtO)4(tert‐BuCOO). The relative amount of Co(thd)3 increases somewhat with decreasing reaction temperature. One third of the cobalt atoms in Co3(thd)3(EtO)4(tert‐BuCOO) retain their original CoII state (the rest being oxidised to CoIII). With MeOH as solvent negligible amounts of cobalt are available for oxidation since the CoII state instead becomes tied up in Co4(thd)4(MeO)4(MeOH)4 which is virtually insoluble in MeOH. Complete oxidation of CoII to CoIII occurs in 1‐ and 2‐propanol, but apart from Co(thd)3 the composition of the poorly crystalline products could not be identified. The crystal and molecular structures of Co3(thd)3(EtO)4(tert‐BuCOO) have been determined by single‐crystal X‐ray diffraction [a = 9.811(4), b = 22.528(8), c = 50.516(5) Å, β = 99.178(7)° at 150 K; space group P21/c]. The molecular structure comprises a triangular Co3 central cluster linked together by Co–O–Co bridges. The arrangement in the central cluster can be viewed as a cuboid‐resembling Co3O4 configuration (viz. a Co4O4 cuboid with one cobalt vertex vacant). The coordination of the CoIII atoms is approximately octahedral whereas that of the penta‐coordinated CoII atoms is distorted square pyramidal.

Published: October 2011

AbstractThe complex [Cr(cyclam)(acac)](ClO4)2·0.5H2O (cyclam = 1,4,8,11‐tetraazacyclotetradecane; acac = acetylacetonate) was prepared and structurally characterized by single‐crystal X‐ray diffraction at 100 K. The chromium atom is in a slightly distorted octahedral environment with four nitrogen atoms of the macrocyclic ligand and two O‐bonded acac molecules in cis position. The cyclam ligand adopts the folded cis‐V configuration with six‐ and five‐membered chelate rings in chair and gauche conformation, respectively. The average Cr–N(cyclam) and Cr–O(acac) bonds are 2.080(4) and 1.941(3) Å, respectively. The IR and visible spectral properties are also described.
Thermal Stability and Acidic Strength of Preyssler‐Type Phosphotungstic Acid, H14[P5W30O110Na] and It's Catalytic Activity for Hydrolysis of Alkyl Acetates

Published: October 2011

AbstractFull structural analysis of Preyssler‐type phosphotungstic acid, H14[P5W30O110Na], using 183W NMR, 31P NMR, and IR spectroscopy, as well as complete elemental analysis revealed that H14[P5W30O110Na]·44H2O was obtained in pure form. H14[P5W30O110Na] started to decompose by heating at 373 K and was less stable than Keggin‐type phosphotungstic acid, H3PW12O40·6H2O, which was stable even after heating at 673 K. Acidic strength measurements using trimethyl phosphine oxide (Me3P=O) as a probe molecule indicated that the acidic strength of H14[P5W30O110Na] was greater than that of H3PW12O40 on the basis of the amount of acid in an aqueous solution. H14[P5W30O110Na] was less active than H3PW12O40 for hydrolysis of alkyl acetates on the basis of acid amount. However, H14[P5W30O110Na] was more active than H3PW12O40 for hydrolysis of alkyl acetates with small alkyl groups on the basis of catalyst weight because acid amount per weight of H14[P5W30O110Na] was about two times higher than that of H3PW12O40.

Published: October 2011

AbstractUnlike replacement therapy by infusion of exogenous recombinant lysosomal enzymes, pharmacological chaperones aim at a gain of function of endogenous gene products. Deficits resulting from missense mutations may become treatable by small, competitive inhibitors binding to the catalytical site and thus correcting the erroneous conformation of mutant enzymes. This may prevent their premature degradation and normalize intracellular trafficking as well as biological half‐life. A major limitation currently arises from the huge number of individual missense mutations and the lack of knowledge on the structural requirements for specific interaction with mutant protein domains. Our previous work on mutations of the β‐galactosidase (β‐gal) gene, causing GM1 gangliosidosis (GM1) and Morquio B disease (MBD), respectively, characterized clinical phenotypes as well as biosynthesis, intracellular transport and subcellular localization of mutants. We recently identified an effective chaperone, DL‐HexDGJ (Methyl 6‐{[N2‐(dansyl)‐N6‐(1,5‐dideoxy‐D‐galactitol‐1,5‐diyl)‐ L‐lysyl]amino} hexanoate), among a series of N‐modified 1‐deoxygalactonojirimycin derivatives carrying a dansyl group in its N‐acyl moiety. Using novel and flexible synthetic routes, we now report on the effects of two oligofluoroalkyl‐derivatives of 1‐deoxygalactonojirimycin, Ph(TFM)2OHex‐DGJ (N‐(α,α‐di‐trifluoromethyl) benzyloxyhexyl‐1,5‐dideoxy‐1,5‐imino‐d‐galactitol) and (TFM)3OHex‐DGJ (N‐(Nonafluoro‐tert‐butyloxy)hexyl‐1,5‐dideoxy‐1,5‐imino‐d‐galactitol) on the β‐gal activity of GM1 and MBD fibroblasts. Both compounds are competitive inhibitors and increase the residual enzyme activities up to tenfold over base line activity in GM1 fibroblasts with chaperone‐sensitive mutations. Western blots showed that this was due to a normalization of protein transport and intralysosomal maturation. The fact that the novel compounds were effective at very low concentrations (0.5–10 μM) in the cell culture medium as well as their novel chemical character suggest future testing in animal models. This may contribute to new aspects for efficient and personalized small molecule treatment of lysosomal storage diseases.

Career history and motivations for choosing LIS: a case study at Aberystwyth University
Authors: Simon Anoush , Taylor Marianne 
Published: October 2011

PurposeThe purpose of this paper is to report on an ongoing project investigating library and information science students' perceptions of the library and information profession and their motivations for undertaking a degree in this field. The analysis presented here focuses on students' reasons for becoming involved in information work, and their motivations for embarking on a professional qualification.Design/methodology/approachThe research was focused on students enrolling on Information and Library Studies programmes in the Department of Information Studies, Aberystwyth University. Students from both undergraduate (UG) and postgraduate (PG) courses are represented over the period 2005‐2010, undertaking campus‐based and distance learning (DL) programmes. A qualitative approach, using focus groups, was taken towards data collection and analysis.FindingsMany students followed a circuitous path into the library and information field, indicating that caution needs to be exercised when making assumptions regarding “typical” library and information workers. Similarly, motivations for attaining a qualification are a complexity of both personal and professional aspirations. Although motivations remain consistent, in line with previous studies, it is argued that “either/or” attitudes to traditional and modern aspects of information work are being replaced by a flexible understanding of the modern profession.Originality/valueThe paper builds on and adds new perspectives to literature on student motivations and career aspirations. The groups studied are eclectic, including PG and UG, full‐time and DL cohorts across a range of age groups.

Next, the case of a business school's experience with EQUIS is used to identify core‐capabilities.FindingsThe paper emphasizes three core‐capabilities that are strengthened through the EQUIS accreditation process: strategizing, changing and branding.Originality/valueThe paper argues that an accreditation process characterized by cyclical assessments and floating standards incorporates the features of a sustainable strategy for continuously developing capabilities within business schools.
Effects of platforms on new product development projects
Authors: Pasche Maximilian , Persson Magnus , Löfsten Hans 
Published: October 2011

PurposeThe purpose of this paper is to investigate effects of platforms on new product development (NPD) projects. Emphasis has been put on the following effect categories: project performance, process changes, and the use of performance measurements.Design/methodology/approachThe paper is based on data collected in a survey of Swedish manufacturing firms. The survey collected data on platform characteristics and NPD characteristics. This paper reports correlations and regression analyses of the different variables.FindingsThe application of a platform strategy leads to a significant increase of component commonality on the product program level. However, it was observed that firms still have problems with sticking to project budgets in terms of cost and lead‐time restrictions. Moreover, platform implementation often involves significant process adaptations. Finally, it showed that firms are hardly applying measurements to follow up on their platform‐related activities.Research limitations/implicationsIt appears that predictions made in current literature regarding platform effects are not generally valid for all firms. Therefore, this study indicates that there may be contingencies affecting the applicability of a platform strategy for specific firms.Practical implicationsOwing to potential contingencies affecting the applicability of platforms, firms have to carefully consider if a platform strategy is promising in their specific situation. Moreover, product platform implementation does not only demand an adaptation of product structures but also involves significant process adaptations.Originality/valueBy statistically testing effects of platforms on product development performance, the tendency of the current literature towards case‐based research is overcome. Hereby, the findings of current literature are challenged in terms of their generalizability.
A citation study of public health Masters' theses
Authors: Klassen Timothy William 
Published: October 2011

PurposeThe purpose of this paper is to devise methodologies and attain results that would allow the author to evaluate local collections that support public health users.Design/methodology/approachThe largest available source of data was local Masters' student theses. The methodology is a case study employing citation analysis of Masters' theses.FindingsThe study provided a list of the journals most used by Masters' students in their theses to be compared to currently subscribed titles to evaluate local holdings. It confirmed that ISI journal rankings were not a useful tool for local collection building.Originality/valueThe study provides a methodology for evaluating and improving the local journal collection and could be combined with further studies to create a core list of public health journals locally. It also provides guidance on types of resources to buy and confirmed the importance of journals to the collection. The study could be combined with similar studies at other institutions to create a broad‐based core journal list.

Authors: Chan Joseph H.L. , Chan Daniel W.M. , Lam Patrick T.I. , Chan Albert P.C. 
Published: October 2011

PurposeThe purpose of this paper is to identify the party most preferred to take the risks associated with the target cost contracts and guaranteed maximum price contracts (TCC/GMP) in the Hong Kong context.Design/methodology/approachAn empirical questionnaire survey was conducted with the relevant industrial practitioners to solicit their preferences of risk allocation in TCC/GMP construction projects in Hong Kong.FindingsThe survey findings indicated that risks on tender documentation and project design are better borne by clients, while construction related risks are perceived to be taken by contractors. The research findings are consistent with other similar studies on risk allocation in construction projects in general.Practical implicationsThis paper has developed a preferred risk allocation scheme for the delivery of future TCC/GMP projects, taking Hong Kong as an example. It can serve as a useful guide for decision makers to determine an optimal risk allocation at the planning stage of a TCC/GMP scheme.Originality/valueThe paper can benefit both academic researchers and industrial practitioners in generating an equitable risk sharing mechanism for TCC/GMP projects. It provides sufficient empirical evidence, added to the growing body of knowledge and lays a solid foundation for further research such as an international comparison of various risk allocation schemes associated with this kind of contractual arrangement.

PurposeThis work is part of a research project that seeks to gain insight into the applicability of different actor analysis methods. This paper aims to describe the analysis of the predictive value of two different actor analysis methods applied to the redesign of the water management of a Dutch polder.Design/methodology/approachThe paper's approach is a parallel application and comparison of the results of two separate actor analysis methods: conflict analysis and transactional analysis.FindingsTransactional analysis was more accurate regarding the prediction of the real world outcomes than conflict analysis.Research limitations/implicationsThe choice of analysis method may be of significant influence on the quality of understanding of the risks involved with different stakeholders. There may not be a single silver bullet.Practical implicationsAn asset manager needs to apply multiple actor analysis techniques to fully grasp the impact of the threats posed by the stakeholders on the asset and its risk register.Originality/valueThe parallel application of the two methods and comparison of their predictive value is new.
Ownership and size as predictors of incentive plans within Swedish real estate firms
Authors: Azasu Samuel 
Published: October 2011

PurposeThis paper seeks to investigate the significance of ownership and firm size as predictors of the prevalence of incentive plans in Swedish real estate firms.Design/methodology/approachUsing survey data for two periods (2003 and 2007), a two‐predictor logistic model was fitted to the data to test the relationship between ownership and firm size and the likelihood that a Swedish real estate firm has an incentive plan.FindingsPrivate sector firms are more likely than government sector firms to use incentive plans. The number of employees was not a significant predictor of which firms were likely to have incentive pay.Research limitations/implicationsThere are other determinants of incentive pay that were not covered.Practical implicationsThe absence of incentive pay does not necessarily hamper a firm's ability to attract high‐quality workers if they take a broader view of the concept of reward. In addition, public sector workers may be motivated by factors other than monetary reward.Originality/valueThis is the first study of the determinants of incentive plans for real estate firms in Sweden.

Published: October 2011

PurposeThe purpose of this paper is to investigate the outlet of a special glass melting system, which is used to control melt flow and modify flow pattern.Design/methodology/approachNumerical calculations in ANSYS and ANSYS CFX were used to study electromagnetic, thermal, hydrodynamic and chemical mixing processes, results are validated by comparison with experimental data.FindingsObtained results show that investigated approach can improve glass melt chemical homogeneity significantly – Lorentz force driven melt movement in conjunction with diffusion process ensures good mixing quality.Research limitations/implicationsThe mixing in glass melt is present only in azimuthal direction (in cylindrical coordinate system associated with outlet tube axis) but the radial homogenization is determined by diffusion only.Practical implicationsThe experiments in JSJ GmbH with soda lime glass were successful and showed mixing effect in output material, thus providing additional method for glass production.Originality/valueAlthough the electrical conductivity of glass is very low, the melt motion is generated by EM forces in this equipment, thus this approach is innovative in glass production technology where typical motion source is buoyancy or mechanical mixing.
