A knowledge value creation model for knowledge‐intensive procurement projects

Purpose – The purpose of this paper is to propose a knowledge value creation model to evaluate and interpret knowledge conversion effects and knowledge value creation for knowledge‐intensive procurement projects.Design/methodology/approach – To depict the knowledge‐conversion processes and knowledge value creation, two portions are undertaken in the model: quantifying the success of every knowledge conversion; and analyzing and interpreting effects on each conversion process and the entire procurement project. A case study for the model implementation is provided.Findings – In the case study, four factors of “performance improvement,” “project learning,” “project comprehension,” and “project value” cover the importance from knowledge workers' perception. However, attitudes of indirect knowledge workers toward instant project learning are not as aggressive as those of the direct project workers.Originality/value – Systematic thinking based on knowledge management (KM) is required in order to feasibly and e.
Carbon Dioxide Emission Prediction of Five Middle Eastern Countries by Using Artificial Neural Network

Greenhouse Gases (GHGs) emission has considerable impact on global warming and climate change. Since energy systems and their features noticeably influence on the amount of GHGs emission, it can be modeled based on the specifications of energy sources utilized by the countries. In addition, economic activity is another factor which should be considered in GHG emission modeling. In this work, Artificial Neural Network (ANN) is used for estimating carbon dioxide emission, as one of the most abundant GHGs, on the basis of shares of various energy sources used as primary energy supply and GDP as an indicator for economic activities. Five countries including Iran, Kuwait, Qatar, Saudi Arabia and United Arab Emirates (UAE) are considered as case studies. Comparing between the estimated data by the achieved model and actual quantities showed acceptable precision of the ANN model for prediction of carbon dioxide emission. The average absolute relative error and the R-squared values of the GMDH model are approximately 2.28% and 0.9998, respectively. The obtained values for the mentioned statistical criteria show the precision of the model in forecasting the emission of Co2.
An investigation into the effectiveness of the reward system in the government sector in the Sultanate of Oman and the potential for introducing a total reward strategy

The problem of the migration of talent from developed countries is not a new one, andessentially it is understood that the reward systems of the countries involved are at faultin not providing individuals with rewards that they value. In the Sultanate of Oman,such a brain drain is not yet a problem, but over the last few years there has been anincreasing departure of talented people from the Omani Government Sector, as theprivate sector has more to offer. Such a phenomenon is wasteful in respect of thetraining investment which might have been made in these people, but it is alsodamaging to the government sector as a whole since the aim of providing qualityservices to the nation is made more difficult to achieve as employees of high calibreleave.Consequently, this thesis explores the issue of why people resign from the governmentsector to work elsewhere, and in so doing it focuses on the current reward system withinthe sector. Through a comprehensive literature review, it considers both academic andpractitioner perspectives on the issue of reward, concentrating particularly on theconcept of Total Reward which embraces the notion of a mixture of wide-rangingtangible and intangible rewards that are designed with employee involvement to ensuretheir attractiveness, and to ultimately secure loyalty and reduce employee turnover.The study then conducts an empirical exercise in which a large sample of governmentemployees from the full range of ministries where resignations are taking place,participate in a questionnaire survey, seeking to establish their views on the currentreward system and the potential for the introduction of a Total Reward strategy.Additionally, a number of in-depth interviews are held with employees, and focusgroups are also conducted, as a means of securing a third source of empiricalinformation. The data obtained is triangulated to establish a detailed employerperspective, and then considered in the light of the literature.The finding is that the reward system in its current form is not appropriate since it doesnot cater for employees? needs. It is characterised by a lack of rigorous and transparentcriteria on which to assess employees? eligibility for various rewards, and consequently,has allowed favouritism and nepotism to creep into a system that was intended to beoperated on the basis of merit. This is dispiriting for employees who have no faith intheir managers to determine their individual performance, and hence offer rewards on afair basis.It is concluded that a Total Reward strategy is a desirable way forward since this wouldstem the flow of talented people from the government sector, but it is alsoacknowledged that there are critical success factors associated with the implementationof such an initiative and that for these to be in place, a culture change within thegovernment sector would need to occur.
Relationship between Nurse Knowledge and Decision Making of Code Blue Activation in Rsud Bangil Pasuruan, Indonesia

Background: The Code Blue system at RSUD Bangil Pasuruan was formed in the context of the safety of patients, visitors, and employees who experience heart and respiratory failure in the hospital area. The Code Blue team is a team that can carry out continued life assistance quickly, thereby reducing the incidence of death in hospitals. In its application, The Code Blue system of RSUD Bangil Pasuruanwas running less than optimal. The death process of inpatients who should have received basic life support assistance by The Code Blue team often ended in death without any effort to activate the available code blue system. The nurse knowledge factor is thought to have a connection with the constrained implementation of The Code Blue system in RSUD Bangil. Objective: This study aims to identify the relationship between nurse knowledge and the decision making of code blue activation in RSUD Bangil Pasuruan. Method: This quantitative study used an analytic observational design with a cross-sectional approach. Respondents of 101 nurses in general inpatients were selected based on a purposive sampling quota technique. The research instrument was a questionnaire for all variables. Results: A bivariate analysis using Spearman rank correlation showed that there was a significant, positive (unidirectional) and very weak relationship with nurse knowledge of the decision making of code blue activation in RSUD Bangil Pasuruan Conclusion: Nurse knowledge needs to be improved to optimize the decision of code blue activation in RSUD Bangil Pasuruan.
Liquid crystal tunable microstrip patch antenna

A microstrip patch antenna operating in the 5 GHz range and tuned by liquid crystal (LC) is described. The simulated tuning range is 8 while the measurements showed a range of 4. Losses in the commercially available LC material at these frequencies give rise to antenna efficiencies ranging from 35 40 at best and falling to around 20 when the LC is in the unbiased state.
Pitch perception and harmonic resolvability in normal-hearing and hearing-impaired listeners

Listeners with sensorineural hearing loss are often impaired in their ability to perceive the pitch associated with the fundamental frequency (FO) of complex harmonic sounds. Four studies investigated the relationship between FO discrimination performance and the ability to resolve individual harmonic frequencies of a complex, testing the hypotheses (1) that the accurate FO discrimination performance associated with low-order harmonics is due to their being resolved, and (2) that listeners with sensorineural hearing loss experience a pitch discrimination deficit due to a reduction in frequency selectivity. The first study revealed that resolved harmonics were not sufficient for accurate FO discrimination. Increasing harmonic resolvability by presenting even and odd harmonics to opposite ears did not improve pitch discrimination, raising the possibility that complex-tone pitch discrimination is not governed by harmonic resolvability per se, but is related to harmonic number. Based on this idea, the second study found that an autocorrelation model of pitch perception, modified to include place dependence by limiting the range of periodicities accurately processed by a given frequency channel, could account for the more accurate FO discrimination associated with low-order harmonics without relying on harmonic resolvability. However, further results in the third and fourth studies suggested a role for harmonic resolvability in pitch discrimination, inconsistent with the lack of dependence on resolvability of the modified autocorrelation model. In normal-hearing subjects at high stimulus levels and in hearing-impaired subjects, a wider spacing between adjacent frequency components, related to a reduction in frequency selectivity, was required to yield accurate FO discrimination performance. Thus, resolved harmonics may be necessary for accurate FO encoding, and the pitch discrimination deficit associated with sensorineural hearing loss may be related to a reduction in frequency selectivity. These results support spectral or spectrotemporal pitch models that derive FO from resolved harmonics, or a place-dependent temporal model whereby peripheral filter bandwidths limit the range of detectable periodicities. Because spectral processing plays an important role in pitch discrimination, hearing-impaired and cochlear-implant listeners may benefit from hearing-aid fitting procedures and cochlear-implant processing algorithms that emphasize or enhance spectral place cues.

SCENT Trial.

Background and Purpose- To evaluate the safety and effectiveness of the Surpass Flow Diverter (Surpass; Stryker Neurovascular, Fremont, CA) in the treatment of large or giant wide-neck intracranial aneurysms at one year, we hypothesize that treatment with Surpass meets or improves on historical safety and efficacy end points. Methods- SCENT trial (Surpass Intracranial Aneurysm Embolization System Pivotal Trial to Treat Large or Giant Wide Neck Aneurysms) is a multicenter, prospective, single-arm, nonrandomized, interventional trial of the Surpass Flow Diverter for uncoilable or previously treated but failed aneurysms of the intracranial internal carotid artery extending from the petrous segment to the carotid terminus at its bifurcation into anterior and middle cerebral arteries. For enrollment in SCENT, target aneurysms had to be wide-neck (≥4 mm) and large or giant size (≥10 mm). Study results are compared with performance goals derived from a thorough review of the medical literature. The primary effectiveness end point included 3 components: complete aneurysm occlusion, absence of significant parent artery stenosis (≥50%), and no retreatment at 12 months. The primary safety end point was major ipsilateral stroke (increase in National Institutes of Health Stroke Scale score of ≥4) or neurological death within 12 months. Results- At 26 medical centers, 180 patients with 180 target aneurysms were enrolled in the modified intention-to-treat cohort. Per angiographic core lab assessment, there were 15 (8.3%) fusiform, 164 (91.1%) saccular aneurysms, and 1 (0.6%) blister aneurysm. Mean aneurysm size was 12.0 mm. Thirteen (7.4%) aneurysms were giant (≥25 mm). Fifty-eight (32.2%) aneurysms were located in the supraclinoid and distal (including posterior communicating artery) segments of the internal carotid artery. Mean procedure duration was 53.6 minutes. The device was successfully implanted in 97.8% of patients with a mean of 1.1 devices per patient. SCENT met both primary safety and effectiveness end points: 12-month primary effectiveness rate was 62.8% [(113/180); 95% CI, 55.3-69.9] and 12-month major ipsilateral stroke or neurological death rate was 8.3% [(15/180); 95% CI, 4.7-13.4]. Conclusions- Surpass provides safe and effective flow diversion of large or giant, wide-neck, intracranial internal carotid artery aneurysms.

Managing the virtual team and controlling effectiveness

The design, manufacture and delivery of a product require even-higher levels of expertise and resource. Companies are finding that better internal and external communications can help leverage these resources to better effect; hence, there are initiatives such as simultaneous engineering, knowledge management and team working. These are being supported by ever-increasing expenditure on Information Technology (IT) infrastructures, such as Intranets, Extranets and Enterprise Resource Management systems such as SAP-R3. Virtual Teamworking has been suggested as a new solution, and is the use of IT to support multidisciplinary teamwork between experts separated by distance and time. This paper describes current collaborative practices in the automotive supply chain, and identifies some crucial issues that need to be addressed for successful implementation of virtual teams. Based on these issues identified from a literature survey and from practical trials and observations, an outline methodology for implementing effective virtual teams and managing them successfully is described. Behind the scenes of public declarations of success in adoption lies a struggle to realize significant benefits. Virtual teaming, to implement concurrent engineering, is not specifically addressed in the published literature. This paper focuses on this and uses data and observations from real teams doing real concurrent engineering work in the automotive industry.
Elastic properties of the tobacco leaf.

Abstract A stress–strain model was determined for elastic parameters of the tobacco leaf that permitted comparison among leaves of different characters. Tests were made (1) on leaves from three stalk positions, (2) at two rates of loading, and (3) at four nominal leaf moisture contents. Tangent modulus at the inflection point and the secant modulus at failure were discovered to be the most definite basis for differences observed in model curves due to stalk position, loading rate and moisture contents. The coefficients of the last two terms of the model also showed some potential as indicators of elasticity at lower moisture contents. The most effective separation of effects occurred below 20% moisture content (w.b.). Energy absorbed and stress and strain values showed variation with treatment but lacked repeatability across treatments to be used as indicators of leaf character. Elastic parameter values were affected by rate of loading as well as moisture content and effective evaluation will require identification of both.
Correlating Visual Grading with NTD Methods for Assessing Timber Condition in Historic Buildings

This study aimed to develop, apply and assess a visual grading system that could evaluate the preservation state of historic buildings structural timbers and correlate it with three NDT methods that are widely used during diagnostic surveys. Assessing timber condition is crucial not only for the structural analysis of buildings, but also for reinsuring that well preserved original material of Cultural Heritage will not be lost. However, assessment based only on NDT results may be biased as it depends on many parameters such as i) the natural variability of wood ii) the type and degree of deterioration iii) the experimental conditions e.t. c. Furthermore, results obtained are not always coinciding and they are often unrelated to the macrosopic condition of timbers. Therefore, this work investigates comparatively a grading system developed based on European with results obtained from ultrasounds application, resistograph profiling and X-ray radiation. The three NDT techniques were tested on samples coming from a post Byzantine mansion in Athens, which presented various types and degrees of decay. For comparison reasons techniques were applied on sound wood of the same species also. Prior to NTD implementation, samples were conditioned in two different RH in order to examine the role of wood moisture on NTD results.
Adaptive control of a flexible linear array

A system has been constructed which adaptively corrects for an applied phase error along the length of a flexible linear array. The system utilises resistance strain gauges and electrically controlled ferrite phase shifters. Results at 9.4 GHz are presented, in the form of radiation patterns, to provide an illustration of the system performance.
Frequent colonization of betahaemolytic streptococci at various body sites including the perineum and anal canal during erysipelas and cellulitis

Abstract Background: Erysipelas and cellulitis are usually caused by betahaemolytic streptococci but the aetiology is often difficult to verify in clinical practice. Methods: Patients with erysipelas or cellulitis were analysed for betahaemolytic streptococci in samples from multiple body sites, including the perineum and the anal canal, during the acute episode and at follow up. Healthy control persons were sampled from the same sites. Results: Betahaemolytic streptococci group A, C or G were identified in 23/28 (82%) patients, most commonly group G. A wound or ulcer, present in 16/28 (57%), was colonized in 8/16 (50%). The perineum and anal canal were colonized in 11/28 (39%) and 10/28 (36%), respectively. At follow-up after about 4 weeks, only 4/28 (14%) were colonized (p<.001). In 39 healthy control persons, no betahaemolytic streptococci group A were found, groups C or G were found in 4/39 (10%). Group B streptococci were more often identified in controls, than in patients,12/39 (31%). Conclusions: Acute episodes of erysipelas or cellulitis are associated with colonization of betahaemolytic streptococci at multiple sites including the perineum and anal canal, in particular serogroup G. This may be important for choice of primary antibiotic therapy and possibilities for prevention of relapses.
Suspended Solids Specifications for Water Injection From Coreflood Tests

A method based on the results of laboratory coreflood tests is proposed for predicting the injectivity decline rate of water injectors. The aim of this method is to provide design specifications for water treatment and injection facilities and procedures with which well injectivity behavior can be analyzed. To illustrate the results that can be obtained with the proposed method, data from coreflood tests are used to construct injectivity-decline-rate curves for an arbitrary injection well.
Ultrahigh-speed InGaAs/GaAs MQW lasers with C-doped active regions

We describe short-cavity In0.35Ga0. 65As/GaAs multiple quantum well (MQW) lasers with undoped and p-doped active regions. The epilayer structure consists of four 5.7 nm QWs separated by 20.1 nm barriers in a GaAs core. The cladding layers consist of Al0.8Ga0. 2As. In the case of p-doped devices a 4.5 nm carbon (C)-doped region (2.5 multiplied by 1019 cm-3) was inserted above each QW, separated by a 3.1 nm GaAs spacer, resulting in a modulation-doped core region. Using a CAIBE process, short-cavity ridge-waveguide lasers are fabricated in a triple-mesa geometry suitable for on-wafer probing. The best device (6 multiplied by 130 micrometers squared) with an undoped active region attained a damping-limited direct modulation bandwidth exceeding 40 GHz at a cw bias current of 160 mA. In contrast, the p-doped devices, demonstrating a maximum bandwidth of 37 GHz, are still limited by power dissipation. (alpha) -factors as low as 1.4 and 1.5 for undoped and p-doped devices, respectively, are extracted from measurements of the sub- threshold gain spectra. In addition, we demonstrate eye diagrams at 25 Gbit/s (limited by the pulse pattern generator) for these laser diodes. A complete characterization of dc and rf properties of these lasers is presented.
Low-noise metal-insulator-semiconductor UV photodiodes based on GaN

Au/SiO/sub 2//GaN metal-insulator-semiconductor photodiodes have been fabricated on Si-doped GaN epitaxial layers grown on sapphire by metalorganic vapour phase epitaxy. The insertion of a thin SiO/sub 2/ layer at the metal-semiconductor interface results in a significant decrease in the dark current density, and an increase in the device detectivity by more than an order of magnitude.
Study of prevalence of pre-eclampsia in Vitamin D supplemented vs none supplemented primigravida mothers

Background: Pre-eclampsia is a significant co-morbidity which can have adverse effect on maternal and neonatal outcomes. Recent evidence have suggested that there is a causal association between low levels of vitamin D and development of pre-eclampsia in nulliparous women. Aims and Objectives: To evaluate prevalence of pre-eclampsia in Vitamin D supplemented and non supplemented primigravida mothers. Materials and Methods: A total of 100 primigravida mothers were recruited in the study and divided in to two groups of 50 subjects each. The recruitment was done prior to 20 weeks of gestation wherein 50 patients of interventional group received Vitamin D supplements along with regular antenatal care. Rest 50 patients received only the regular antenatal care. Results: At baseline, hypovitaminosis D in interventional group was noted to be 40% (n=20). A total of 2 patients developed pre-eclampsia in interventional group whereas 9 patients developed pre-eclampsia in control group. The difference was significant with a higher prevalence of pre-eclampsia in control group that did not receive vitamin D supplementation. Conclusion: Vitamin D supplementation should be considered as an essential component in antenatal care which can be associated with lowering the incidence of pre-eclampsia.
Seasonal Variations in the Age-Related Collision Risk of Ontario Drivers

Studies of age-related collision risk have not considered how collision risk varies by season. In 1994, the Ministry of Transportation of Ontario conducted an exposure survey which gathered year-round data to ensure that seasonal variations in collision risk could be measured and analyzed. Three-day trip logs were mailed to a stratified random sample of 11,250 Ontario drivers. The logs were mailed out at the rate of 938 per month. The survey was conducted from December 1993 to November 1994. The mean daily kilometrage for six age groups was estimated, and seasonal collision rates per 1 million km driven were calculated. Drivers aged 80 to 89 show the most dramatic fluctuations in collision risk. The winter collision rate of 22.4 is over three times higher than the rate observed in the fall (6.7). The collision rate in spring (13.4) is twice that observed in the summer and fall. When the youngest and oldest age groups are compared, it is evident that the collision risk of 80- to 89-year-old drivers is 2.0 times higher in winter and about 1.5 times in spring. The youngest drivers, however, have a collision risk that is substantially higher than the oldest drivers in summer and fall.
