Disabling the context for knowledge work: the role of managers' behaviours

Purpose – The purpose of this paper is to analyse issues that prevent knowledge sharing in organisations.Design/methodology/approach – The paper contains content analysis of 691 free text comments about the climate for knowledge sharing provided by 848 employees, primarily knowledge workers, in 92 business units and departments.Findings – The paper finds that two main issues that prevent knowledge sharing are the attitudes of the nearest supervisor and a lack of context‐building information. Apathetic managers, who do not actively encourage business/organisational information, and hypocritical managers, who do not “walk the talk”, are the main management behaviours that prevent knowledge sharing according to their subordinates in the sample. The study also suggests that a lack of organisational context‐building information and knowledge impacts the context negatively and makes knowledge workers less prone to share knowledge also in their work groups.Research limitations/implications – The sample is too sm.
Segmenting Leisure Travelers by Risk Reduction Strategies

ABSTRACT This study is an initial attempt in using risk reduction strategies as the basis for segmenting leisure travelers. Results of the study generated insights into the nature of consumer markets and created three segments of travelers who adopted risk reduction strategies in different ways. The three leisure travelers' segments include: socially reliant risk reducers, self-initiated risk reducers, and unconcerned about risk reduction. Travel behaviors and sociodemographics of the three segments were also compared.

Summarizes the key difficulties of implementing property management software systems as the lack of a systematic IT strategy and the lack of information about software availability. Considers the three main stages of a systematic approach to software selection to be: feasibility in cost and benefit terms, investigation of software options and successful implementation of a system.
EDUCATION AND THE NATIONAL WEALTH OF THE UNITED STATES

Human capital theory has motivated a great many empirical investigations into the relationship between education and earnings potential. These studies test refinements of the theory, but do not attempt to value education for the economy as a whole. This study develops series which track human wealth and its educational components for the United States from 1946 to 1980. Three related educational time sequences emerge: (1) schooling wealth, the present value of the current and future contributions of the existing schooling stock to national income; (2) net change in schooling wealth, the amount added to present value in that year; and (3) schooling investment, the present value of the future contributions of the new schooling conducted in that year. One important lesson of this exercise is that the last two series can be quite different as a result of the pattern of appreciation and depreciation of human wealth over the lifetimes of individuals. Moreover, education increases the age of peak human wealth and thus should shorten the period during which individuals save for retirement. This phenomenon may induce a demographic cycle in the nation's savings rate, especially evidenced with the aging of the baby‐boom cohort. The magnitudes of the human and schooling wealth estimates are large when compared to financial wealth. For a 4 percent rate, the period‐wide average for human wealth is five times‐and schooling wealth 2.6 times‐the Federal Reserve Board's measure of household net worth. These estimates are naturally sensitive to the discount rate chosen, but show that the gap between human and financial wealth has been widening and that the value of schooling provided in any year greatly exceeds its cost. Schooling represents a form of saving whose value is several times the conventional measure of saving.
Essays in Asset Pricing and Applied Micro-Economics

In the first chapter, Christian Goulding and I present a model of asset prices with recursive preferences and the simple consumption growth dynamics of Mehra and Prescott (1985) but relax the assumption that preference parameters are constant over time. We show that rare, temporary, and plausible fluctuations in the elasticity of inter-temporal substitution (EIS) and risk aversion (RA) can quantitatively explain numerous regularities in U.S. asset prices including: the equity premium and risk-free rate puzzles, excess return and consumption growth predictability, a counter-cyclical risk premium and an upward-sloping real yield curve. A novel implication is that time-varying EIS is more important than time-varying RA for explaining many of these regularities, suggesting a new source of risk in investors' ability to plan their consumption over long horizons. In addition, our model can accommodate a behavioral interpretation of psychological factors (e.g. fear) that drive fluctuations in asset prices beyond traditional risk factors. The second chapter is an empirical study of the value of star college athletes. Collegiate athletes in the U.S. are not allowed to be paid directly for their athletic ability. Under the current regulations imposed by the NCAA, any compensation beyond scholarships and grant-in-aid to cover some basic living expenses is forbidden. This artificial constraint on athletes' wages, when university athletic programs are generating significant revenues, has sparked much recent debate over the compensation of college athletes. To help inform this debate, I quantify the value of a NCAA Division 1 FBS (Football Bowl Subdivision) star football and NCAA Division 1 star basketball players by estimating their marginal revenue product using a novel dataset of individual player and team performance statistics and publicly available athletic program revenue data. I find that a star college football player is worth up to $1.2-$2.1 million while star college basketball players are worth up to $655,000-$1.1 million a year. Interestingly, I also find evidence suggesting that a college recruiter's ability to identify revenue generating star players is limited and that the marginal revenue product of star college players declines as the team's media coverage increases.

Lactobacillus acidophilus ATCC 4356 inhibits biofilm formation by C. albicans and attenuates the experimental candidiasis in Galleria mellonella

Probiotic strains of Lactobacillus have been studied for their inhibitory effects on Candida albicans. However, few studies have investigated the effect of these strains on biofilm formation, filamentation and C. albicans infection. The objective of this study was to evaluate the influence of Lactobacillus acidophilus ATCC 4356 on C. albicans ATCC 18804 using in vitro and in vivo models. In vitro analysis evaluated the effects of L. acidophilus on the biofilm formation and on the capacity of C. albicans filamentation. For in vivo study, Galleria mellonella was used as an infection model to evaluate the effects of L. acidophilus on candidiasis by survival analysis, quantification of C. albicans CFU/mL, and histological analysis. The direct effects of L. acidophilus cells on C. albicans, as well as the indirect effects using only a Lactobacillus culture filtrate, were evaluated in both tests. The in vitro results showed that both L. acidophilus cells and filtrate were able to inhibit C. albicans biofilm formation and filamentation. In the in vivo study, injection of L. acidophilus into G. mellonella larvae infected with C. albicans increased the survival of these animals. Furthermore, the number of C. albicans CFU/mL recovered from the larval hemolymph was lower in the group inoculated with L. acidophilus compared to the control group. In conclusion, L. acidophilus ATCC 4356 inhibited in vitro biofilm formation by C. albicans and protected G. mellonella against experimental candidiasis in vivo.
Grid Resource Allocation for Real-Time Data-Intensive Tasks

Grid resource allocation mechanism maps tasks to the available grid resources according to some predefined criterion, such as minimizing makespan or execution cost, load balancing, energy efficiency, maintaining user-defined task deadlines, and efficiently using resource memory. The minimization of the makespan is a dominant criterion and is more challenging when computationally intensive tasks have real-time deadlines and data requirements. Such tasks require data files for processing that are transferred from data storage resources to the computing resources, which consume network bandwidth. Resource allocation mechanism for these tasks takes into account the data files transfer time and processing power of the computing resources to complete execution within deadlines. The problem of allocating real-time data-intensive tasks to the grid heterogeneous computing resources with the assumption that the data resources are decoupled from the computing resources, remain challenging. This paper addresses the aforementioned problem as the global optimization problem by considering heterogeneous computing resources of various processing capabilities connected to the data storage resources by network links of various bandwidths. We have analytically formulated the resources with the aim to maximize total number of mapped tasks while possibly minimizing the makespan subject to the time QoS constraints of deadlines, execution time, and data files transfer time. The experimental results reveal that the proposed technique outperforms the other alternatives when real-time tasks are considered.
Border innovation management, improved passenger services and satisfaction acceptance

Due to trade globalisation and the high growth of international population shift, the world information on the use of biometrics in border management, to improve border security, services, efficiency, traditional airport customs clearance procedures by the human service does not only have high labour cost, but is time-consuming and easy to have errors. With the scientific and technological progress, Taoyuan International Airport also enhances airport-related hardware by building automated immigration clearance system, which make customs inspection with high accuracy and less time, this also leads to effective use of manpower and space. This study was to take passengers that use the automated immigration clearance system as the research object, and use the questionnaire method to investigate about: 1) passengers' attitude by ease of using automated immigration clearance system; 2) using attitude corresponding to the acceptance of actual use; 3) using attitude corresponding to satisfaction of the actual use. The contribution of this research provides organisations with a systematic innovation management and reference for airport renovation projects.

Branding Europe – Between Nations, Regions and Continents

Abstract The aim of this paper is to explore a common European tourism marketing initiative orchestrated by the organisation European Travel Commission (ETC) and communicated via www.visiteurope. com. Particular focus is given to the position of the Nordic countries – how they are depicted and which imagery is used to represent these countries. The paper raises the question whether it makes sense to name the initiative a “Brand Europe” as suggested by the president of ETC and whether common denominators are sought thereby facilitating the creation of a European brand profile, or whether the website is just a collection of links to national websites thereby functioning as a medium for national tourism destination promotion. Theoretically the point of departure is taken in place‐branding theory, and scrutinising this literature it appears that attention has centred on branding the city and the nation whereas little attention has been paid to branding supra‐national entities. In this article focus is on stakeholder interests and consumer images and their implications on communicative choices in place‐branding efforts. The analysis shows that www.visiteurope. com, on the one hand, is a shared European platform which thematically sketches experiences to be had in Europe, and which constitutes more than just the marketing from national destinations in Europe. On the other hand, it is hardly possible to term this initiative “a brand” as it lacks a holistic approach not only to promotion but also product development. Keywords in the shared profile are diversity, history, culture and nature that, taken together, stand out as quite a generic catch‐all presentation of Europe, however, there seems to be potential in the place‐branding concept that can be exploited more extensively in future, also at the supra‐national level of Europe as a destination. The Nordic countries appear as a region “in the far corner of Europe” presented as primarily a location with extreme nature conditions and exotic cultural habits combined with peaceful, sunny café environments which only links up marginally with the overall European profile. Still, for a relatively unknown region in the global tourist market, it is deemed relevant for the Nordic countries to be part of a European brand in future, but the integration of a regional profile into a future European brand needs substantial development.
A SDP Approach for Range-Free Localization in Wireless Sensor Networks

Location awareness is of great importance for many wireless sensor network applications. However, it is too expensive to equip all nodes with GPS receivers or configure the location for each node manually. Consequently, many localization methods have been proposed. While most of them are range-based, we propose a range-free localization method, which is based on semidefinite programming. The method can be not only used for relative localization but also for absolute localization. Extensive simulations have been conducted. The results show that 1) the method performs better with fewer anchors, especially for relatively uniform networks of high connectivity level, and 2) the method is more robust to anchor placement, as compared to the popular MDS-MAP method which is based on multidimensional scaling(MDS) technique. Moreover, the method can intrinsically keep the proximity of neighbor nodes, whether the network is regular or not.
Contact hypersensitivity to topical corticosteroids

Topical corticosteroids are increasingly recognized as relatively common contact sensitizers. Between July 1988 and December 1991 2687 patients undergoing routine patch testing were also tested with tixocortol pivalate (TP). Over the same time period 528 patients were selected for testing with a series of 18 steroids. One‐hundred and thirty‐one cases (4·9%) of corticosteroid hypersensitivity were detected and 119 (90·8%) of these cases were positive to TP, Thirty‐seven patients reacted to one or more steroids in the steroid series, the most frequent sensitizers being hydrocortisone, budesonide (3·6%) and hydrocortisone 17‐butyrate (2·5%), Of these 37 cases, 20 (54%) reacted to more than one steroid simultaneously, but the patterns of cross‐reaction were not consistent with previously suggested groupings. Screening for steroid allergy should be performed as part of standard patch testing. The value of TP as a marker of corticosteroid hypersensitivity is reinforced by this study, but no satisfactory marker was found for the 9·2% of cases not detected by TP. There remains a need for further markers of corticosteroid hypersensitivity, A prevalence of 4·9% of corticosteroid allergy amongst our patients suggests that the frequency of this finding is generally underestimated.
Real Business Cycles and the Lucas Paradigm

When the Lucas paradigm is generalized to include real effects, the effects of real factors and monetary factors on the business cycle are always interrelated. Furthermore, in such models monetary factors can affect the long-run behavior or real output, contrary to the commonly held view that they can't. Real business cycle models and Lucas-type models are different paradigms not in the sense of real versus monetary, but in the interrelation- ships between real and monetary factors intrinsic to the Lucas paradigm as contrasted to the dichotomy between real and monetary factors implied by the real business cycle literature.
Manipulation of Concentration-Conductivity Data of Sodium Dodecyl Sulphate and Sodium Dodecylbenzene Sulphonate in KCl Solution in Relation to Micellisation Parameters

The conductivity of sodium dodecyl sulphate (SDS) and sodium dodecylbenzenesulphonate (SDBS) has been studied in varying concentrations (0-5 mM) of aqueous KCl solution at 25oC. Data analysis was based on the conventional treatment of conductivity-concentration data, differential, and integration methods with the aim of knowing the best method. As expected, the conductivity increased with an increase in surfactant concentration; the plot of which showed a kink at critical micelle concentration, cmc (i.e. point of aggregation). The results showed no apparent relationship between the degree of counterion binding, β and [KCl]; and an inverse relationship between the cmc values and [KCl]. β was within 0.4-0.6 for SDS and 0.1-0.3 for SDBS. The cmc of SDS decreased from ca. 8 to 6 mM and that of SDBS from ca. 2 to 1 mM as the [KCl] increased from 0-5 mM. These values are in mutual agreement irrespective of the method used. It was confirmed that in the absence of KCl, values obtained from the integration method were more consistent with those reported in the literature; therefore this method is recommended as the best method for determination of micellisation parameters provided the process is followed by conductivity measurements.
Results of the PETHEMA ALL‐96 trial in elderly patients with Philadelphia chromosome‐negative acute lymphoblastic leukemia

Background and aim: Only 20–30% of elderly patients with acute lymphoblastic leukemia (ALL) are enrolled in clinical trials because of co‐morbid disorders or poor performance status. We present the results of treatment of Philadelphia chromosome‐negative (Ph−) ALL patients over 55 yr treated in the PETHEMA ALL‐96 trial. Patients and methods: From 1996 to 2006, 33 patients 55 yr with Ph− ALL were included. Induction therapy was vincristine, daunorubicin, prednisone, asparaginase, and cyclophosphamide over 5 weeks. Central nervous system (CNS) prophylaxis involved triple intrathecal (IT) therapy, 14 doses over the first year. Consolidation‐1 included mercaptopurine, methotrexate, teniposide and cytarabine, followed by one consolidation‐2 cycle similar to the induction cycle. Maintenance consisted of mercaptopurine and methotrexate up to 2 yr in complete remission (CR) with monthly reinduction cycles (vincristine, prednisone and asparaginase) during the first year. Results: Median (range) age was 65 yr (56–77). Phenotype (30 patients): early‐pre‐B 7, common/pre‐B 18, T 5. Cytogenetics (28 patients): normal 12, complex 10, t(4;11) 2 and other 4. CR was achieved in 19/33 (57.6%) patients, early death occurred in 12 (36.4%) and 2 (6%) were resistant. Overall survival and disease‐free survival probabilities (2 yr, 95% CI) were 39% (21%–57%) and 46% (22%–70%), respectively (median follow up of 24 months). Removal of asparaginase and cyclophosphamide from the induction decreased induction death (OR 0.119, CI 95% 0.022–0.637, P = 0.013) and increased survival (20% vs. 52%, P = 0.05). Conclusions: The prognosis of elderly Ph− ALL patients is poor. In this study, less intensive induction decreased toxic death, allowing delivery of planned consolidation therapy and increased survival probability.
Drain-conductance optimization in nanowire TFETs

In this work we examine the problem of the nonlinear output characteristics of tunnel FETs, and the related small drain conductance at low drain voltage, which prevents rail-to-rail logic operation and severely degrades the device dynamic properties compared with standard CMOS FETs. The problem is investigated with the help of an analytical model which highlights the constraints of the device design by splitting the effects of the tunneling probability from the density of states in the source, channel and drain, and makes it possible to design a nanowire TFET by an appropriate selection of the material, nanowire size and degeneracy levels in the source and drain regions. So doing, we remove the above characteristics' feature and recover a large drain conductance without degrading the subthreshold slope. The optimized device is numerically simulated using the k·p model, whose results are in fair agreement with the analytical one.
Generator Short-Circuit Torque Compensation in Multichannel Wind Turbines

This paper presents a control solution to damp the torque oscillations that appear in a generator during an unbalanced stator fault. The solution proposed is applicable to a multichannel configuration where a generator with several stators is commanded by parallel-connected power converters. The multichannel structure is introduced by some authors with the goal of increasing the reliability of high-power wind turbines cost effectively. Experimental results are obtained proving the effectiveness of the proposed solution in a nine-phase permanent magnet synchronous generator controlled by three back-to-back converters. The controller shows a good performance and a rapid response canceling the pulsating torque of the short-circuited stator by commanding properly the remaining healthy stators. In this way the risk of damaging the drive train is minimized while the ability to perform a safe stop is guaranteed. The proposed control solution does not require significant modifications of the existing control system since it acts in parallel with the regular controller and reacts instantly when the fault triggers.
A Direct Assessment of the Relation Between Shared Knowledge and Communication in a Referential Communication Task

The present paper introduces away to document quantitatively the changing relation between shared knowledge and communication over time. It is often assumed that people engaged in prolonged interaction come to share more knowledge over the course of interaction, and, further, it is assumed that this increase in shared knowledge enables them to communicate more efficiently with each other. In Experiments 1 and 2, this assumption was evaluated by monitoring the participants' knowledge of the experimental stimuli and their estimates about each other's knowledge periodically during several trials of a referential communication task. The results confirmed that participants developed more shared knowledge over the course of interaction, and that their estimates about shared knowledge become more accurate over successive trials. Experiment 3 was conducted in order to examine whether the use of intervening questionnaires in the earlier experiments prompted the participants to behave differently than they otherwise would. Although the use of the questionnaires encouraged a more active exchange of information, the overall pattern of behavior exhibited by the participants was not affected by this procedure.
