Knowledge management (KM) in information technology outsourcing (ITO) is important to the organizations which pursue long-term strategic benefits and innovation. Effective KM mechanism in outsourcing enables both parties to continuously exchange knowledge and promotes collective learning. This paper investigates the role of Lean principles in supporting KM in ITO relationships. Drawn from the knowledge-based view of the firm, knowledge accessing and knowledge integration and utilization are identified as two key KM processes in outsourcing. Three case studies conducted in different service industries with 18 interviews indicate that the two KM processes were supported by four Lean principles: respect for people, continuous improvement, systems thinking, and proactive behavior. Those principles can be implemented with different tools at different organizational levels. This study reveals the relevance between Lean and KM in ITO relationships, which has not been reported by the KM literature. It also provides implications to ITO practitioners for the implementation of Lean principles.  相似文献

Research and development (R&D) collaboration between universities and business is a vital form of new knowledge creation in knowledge-intensive high-technology business environments. Increasingly, collaboration occurs in networks. A key element in forming these collaborate networks is shared knowledge creation, which is dependent on the Ba, the SECI process, and knowledge assets. This paper argues that Ba plays a major role for successful knowledge creation through R&D collaboration between university and business. A Ba is a perception of a place – which can be virtual – and a shared purpose. The absence of a Ba is a significant barrier to success, but building a Ba takes collaborative time and effort. This paper addresses the problems in the successful formation of such networks based on insights from biotechnology, an area where this type of collaboration has been and still is common, but not always successful or unproblematic.  相似文献

Hepatitis B virus (HBV) infection is a worldwide health concern which is associated with significant morbidity and mortality. Both viral and host factors have a significant effect on infection, replication and pathogenesis of HBV. The aim of this study was to investigate the effect of CYP2E1 and CYP1A1 genetic variants on susceptibility to HBV. 143 individuals including 54 chronic HBV patients and 89 healthy controls were enrolled in the genotyping procedure. rs2031920 and rs3813867 at CYP2E1 as well as rs4646421 and rs2198843 at CYP1A1 loci were studied in all subjects using PCR–RFLP (restriction fragment length polymorphism) analysis. Both variants at CYP2E1 locus were monomorphic in all studied subjects. Genotype frequency of rs4646421 was significantly different between chronic HBV patients and healthy blood donors (P = 0.04, OR 4.31; 95% CI 1.04–17.7). Furthermore, individuals carrying at least one C allele (CC or CT genotypes) for rs4646421 seemed to have a decrease risk of hepatitis in comparison with TT genotype (P = 0.039). Our results showed a relationship between rs4646421 TT genotype (rare genotype) and the risk for developing chronic HBV infection (four times higher). Further studies are needed to examine the role of CYP1A1 polymorphism in susceptibility to chronic HBV infection.  相似文献

The paper explores the intent of knowledge sharing in complex organizational contexts. Findings from semi-structured interviewing with 54 subjects in two large organizations in Saudi Arabia indicate that self-perception and contextual interpretation create tensions that affect the way knowledge is managed and shared. The dichotomy between self-centeredness and self-doubt was found to affect trust and openness necessary for genuine knowledge sharing. Mutual trust, developed through timely self-disclosure, was found to offer psychological safety for employees to share knowledge more openly. Inner tensions become the stimuli for maximizing the social aspect of interaction to negotiate meanings, strategize knowledge sharing, and redefine role identity. The interplay of cognitive and behavioural participation challenges one’s knowing and becoming, increasing the complexity and dynamics of knowledge sharing. Knowledge-sharing intent determines the learning of individuals and learning in organizations. A conceptual framework is introduced and implications for practice are discussed.  相似文献

The objective of the paper is to demonstrate how a sensemaking model of knowledge enables better and deeper understanding of knowledge management (KM) processes in organisations and the role of information technologies (IT) in these processes. Inspired and informed by a sensemaking view of organisations, the model identifies four types of knowledge, corresponding to four sensemaking levels: the individual, collective, organizational, and cultural. Each knowledge type, as the paper shows, is of different nature and has different characteristics but is constituted and affected by all other knowledge types. An organisation is thus seen as a ‘distributed knowledge system’ composed of numerous instances of these four knowledge types and their dynamic interplay. By drawing from three empirical studies, the paper illustrates how the sensemaking model of knowledge can be applied to investigate different ways companies (try to) manage knowledge and use IT-based systems to improve KM and ultimately company performance. A deeper understanding of these processes through the lens of the model reveals mechanisms and forces underlying KM phenomena that help explain why some processes were successful and others failed. The paper intends to make the following contributions: propose a theoretical framework of knowledge and KM in organizations, which is reasonably comprehensive and empirically grounded and also demonstrate its relevance and usefulness to both researchers and practitioners as they investigate and make sense of specific KM processes and IT applications in practice.  相似文献

It is well known that dietary intakes play a pivotal role in pathogenesis of nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH); however, the role of each component of diet has not yet been elucidated. Our objective was to evaluate the effects of onion consumption on prevention of NAFLD/NASH development. Sprague–Dawley rats were fed either high-fat, high sugar diet (model group), or high-fat, high sugar diet plus 7% onion powder (model + onion), or chow diet ad libitum for 7 weeks. Serum levels of fasting glucose, triglyceride, cholesterol, liver enzymes, insulin, and hepatic tumor necrosis factor-alpha (TNF-α) gene expression were determined. Hepatic histology was examined by H&E stain. Model + onion group had significantly lower hepatic steatosis, ballooning, lobular inflammation, and portal inflammation (p < 0.001), lower hepatic TNF-α gene expression (p < 0.001), lower plasma levels of ALT (p = 0.026), AST (p = 0.041), insulin (p < 0.001), TG (p = 0.041), and glucose (p = 0.009) compared with model group; however, weight gain, food intake, plasma total cholesterol and LDL levels were not significantly different between these two groups. Our data indicate that regular consumption of onion can prevent NAFLD even in the presence of the other risk factors such as obesity, hypercholesterolemia, and high energy, fat, and sugar intakes.  相似文献

Adhesion molecules play a key role in cancer progression and tumorigenesis. Genetic polymorphism of adhesion molecules may alter the normal functioning thereby leading to bladder cancer susceptibility. Hence we aimed to evaluate three SNPs of CD166 gene (CD166rs6437585 C/T, CD166rs10511244 C/T, and CD166rs1157 A/G) in bladder cancer patients and normal controls of North Indian population. A total of 270 healthy controls and 240 confirmed bladder cancer patients were recruited for this study. Three SNPs of CD166 gene viz. CD166rs6437585 C/T, CD166rs10511244 C/T, and CD166rs1157 A/G were selected for this study. CD166rs6437585 C/T and CD166rs10511244 C/T were genotyped by Taqman allelic discrimination assay and CD166rs1157 A/G was genotyped by PCR–RFLP. The statistical analysis was done using the SPSS software, version 16.0 (SPSS, Chicago, IL), and p < 0.05 was considered statistically significant. Haplotypic analysis was done by using SNP analyzer version 1.2A. CD166rs6437585 C/T and CD166rs10511244 C/T showed significant association with reduced risk in bladder cancer while CD166rs1157 A/G showed significant high risk along with association at genotypic and allelic levels. Haplotypic analysis showed 1.8-folds risk in CCG combination, whereas CTA and TCG showed significant association with reduced risk. Further stratification on the basis of smoking, tumor grade/stage and BGC therapy revealed no association of these three polymorphic sites of CD166. Our study suggests that CD166rs6437585 C/T and CD166rs10511244 C/T are predictive for the reduced risk of bladder cancer, whereas CD166rs1157 A/G had shown significant association with high risk of bladder cancer in North Indians. This somehow suggests that CD166rs1157 A/G can be used as a marker for risk prediction of bladder cancer.  相似文献

Dependence on alcohol, nicotine and duration of alcohol consumption are known to alter thyroid function tests. This study was conducted to assess the effect of interaction between the duration of alcohol consumption and alcohol dependence on TFT. The subjects consisted of 38 male patients with alcohol dependent syndrome co morbid with nicotine dependent syndrome, 33 male patients with alcohol dependent syndrome and 30 male normal healthy volunteers. Liver function tests, haematological parameters and thyroid function tests were assayed. Two way multivariate ANOVA was used to assess the interaction effect by SPSS 21 package. Multivariate analysis of combined TFT levels revealed no significant (P = .078) difference amongst groups based on alcohol dependence, significant difference (P = .001) amongst groups based on duration of alcohol consumption and no significant (P = .604) interaction effect between duration of alcohol consumption and alcohol dependence. Tests of between subject effects for individual TFT revealed significant (P = .014) difference in T3 between groups based on alcohol dependence, significant difference in the levels of fT4 (P = .001), T3 (P = .07) and T4 (P < .001) between groups based on duration of alcohol consumption was observed. Interaction between the effect of duration of alcohol consumption and alcohol dependence for individual TFT did not reveal any significance. fT4, TSH and T4 levels were significantly low in persons consuming alcohol for more than 20 years. TSH levels were significantly low in ADS compared to controls. Significant decrease in the levels of thyroid hormones was observed as the duration of alcohol consumption increased.  相似文献

Will the proliferation of devices that provide the continuous archival and retrieval of personal experiences (CARPE) improve control over, access to and the record of collective knowledge as Vannevar Bush once predicted with his futuristic memex? Or is it possible that their increasing ubiquity might pose fundamental risks to humanity, as Donald Norman contemplated in his investigation of an imaginary CARPE device he called the “Teddy”? Through an examination of the webcam experiment of Jenni Ringley and the EyeTap experiments of Steve Mann, this article explores some of the social implications of CARPE. The authors’ central claim is that focussing on notions of individual consent and control in assessing the privacy implications of CARPE while reflective of the individualistic conception of privacy that predominates western thinking, is nevertheless inadequate in terms of recognizing the effect of individual uptake of these kinds of technologies on the level of privacy we are all collectively entitled to expect. The authors urge that future analysis ought to take a broader approach that considers contextual factors affecting user groups and the possible limitations on our collective ability to control the social meanings associated with the subsequent distribution and use of personal images and experiences after they are captured and archived. The authors ultimately recommend an approach that takes into account the collective impact that CARPE technologies will have on privacy and identity formation and highlight aspects of that approach.  相似文献

During the recent years the intellectual capital (IC) literature has produced tens of models to support the various IC management (ICM) activities, such as identification, measurement, valuation, acquisition and reporting IC. However, the practice of applying these models seems to be a fairly new issue in many organisations. The gap between research and practice (i.e. not many organisations seem to be applying ICM models) may result from several issues. This paper approaches the gap from two perspectives. First, the paper questions the applicability of ICM models. Second, although IC as a research theme is quite immature many management models that also include some of the aspects of IC have been developed within general management disciplines. Thus, this study examines whether traditional management models may also be suitable for ICM. The two questions are answered by using four single cases in which action research projects were carried out.  相似文献

Three species of Mansonioides vectors viz.,Ma. annulifera, Ma. uniformis andMa. indiana were found in Cherthala taluk, Kerala which is one of the endemic areas due toB. malayi. The immatures of Mansonioides thrive mainly in association with macrophytic hydrophytes such asP. stratiotes, S. molesta andE. crassipes in perennial habitats (ponds, channels/ canals etc.,) andI. miliaceae in seasonal habitats (fallow lands etc.) Breeding potential was higher (130.19) in clean ponds withP. stratiotes, compared to that of polluted ones (40.69). However, the polluted habitats infested with the same host plants were found to be the most productive forMa. annulifera, with an average daily adult emergence rate of 601/100 sq.m.). The clean habitats played a major role in the contribution ofMa. uniformis, whereS. molesta in the perennial habitats and I. miliaceae in the seasonal fallow lands were the favourable plants contributing a daily output of 12.5/100 sq.m and 221.81/100 sq.m. respectively.E. crassipes infested polluted habitats formed the major source forMa. indiana, the emergence rate being 13.89/100 sq.m. The perennial habitats supported mainly the breeding ofMa. annulifera (70.82%), whereas the seasonal habitats contributed the major chunk ofMa. uniformis (92.54%) andMa. indiana (71.43%). The bionomics of Mansonioides mosquitoes are thus shown to be greatly influenced by the community structure of hydrophytes and also the nature of breeding habitats.  相似文献

The X-ray repair cross-complementation group 1 (XRCC1) gene plays an important role in base excision repair pathway. Several studies have reported contradictory results for XRCC1 exon 10 (Arg399Gln, G23990A, rs25487) gene polymorphism and cancer risk in Indian population, making it difficult to interpret them. Therefore, we have conducted a meta-analysis to evaluate the more precise association between XRCC1 exon 10 G>A gene polymorphism and risk of cancer by published studies. We searched PubMed (Medline) and Google scholar web databases to cover all studies published on association between XRCC1 exon 10 G>A gene polymorphism and cancer risk until August 2016. Pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to appraise the strength of association. Heterogeneity, publication bias and sensitivity analysis were also assessed. Twenty-five published studies had fulfilled the inclusion criteria comprising 4131 confirmed cancer cases and 5013 controls. When all studies were polled together, overall significant association was found between XRCC1 exon 10 G>A polymorphism and cancer risk in variant allele carrier (A vs. G: OR 1.217, 95% CI 1.056–1.402, p = 0.007), homozygous (AA vs. GG: OR 1.359, 95% CI 1.036–1.783, p = 0.027), dominant (AA+AG vs. GG OR 1.208, 95% CI 1.006–1.450, p = 0.043) and recessive (AA vs. AG+GG: OR 1.315, 95% CI 1.029–1.680, p = 0.029) genetic models. Further sensitivity analysis supported the stability of our result by showing similar ORs before and after removal of a single study. The present meta-analysis suggested that the XRCC1 exon 10 G>A polymorphism contribute cancer risk in Indian population, and supports that individuals with risk allele A and AA genotype are at higher risk of developing cancer.  相似文献

Cardiovascular disease, as the leading cause of patient death with chronic kidney disease, could be predicted by carotid atherosclerosis. The aim of the present study was to evaluate a possible relationship between serum soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and Vitamin D levels with mean right/left carotid intima-media thickness (cIMT), in the hemodialysis (HD) patients. In this cross-sectional study, serums were obtained from 50 stable chronic HD patients and 39 healthy controls. The serum levels of sTWEAK, Vitamin D, intact parathyroid hormone (iPTH) in both groups, and cIMT were determined in HD patients by standard methods. Serum levels of sTWEAK were higher [808.8 (521.6–5032.4) pg/ml vs. 664.4 (487.4–2955.8) pg/ml (p = 0.006)] and Vitamin D levels were lower [13.4 (2.5–153) ng/ml vs. 27.8 (18.4–59.0) ng/ml (p = 0.001)] in the hemodialysis patients than in the healthy control. No important correlation was found between sTWEAK Vitamin D levels (r = 0.010/p = 0.946), and mean right(r = ?0.194/p = 0.178) and left (r = 0.061/p = 0.673) cIMT in the HD patients. Our study shows that sTWEAK levels are elevated in HD patients. This elevation has no association with the cIMT.  相似文献

On the basis of the Chinese schema, we propose that internal social capital manifests itself in the form of ‘guanxi’, trust, and norms. We discuss the concept of interpersonal relationships within the context of Chinese culture by embedding the guanxi concept into a model to investigate the relationships among the three dimensions. We used a survey-based methodology to collect data from 230 employees of the top 100 high-technology firms in Taiwan and structural equation modelling (SEM) with LISREL 8.54 to examine the hypotheses model. The results indicated that at the individual level, guanxi is positively related to both trust and norms, which are also positively related to knowledge sharing. The mediating effects of trust and norms were also found to be significant. Trust directly influences knowledge sharing, and plays a mediating role between knowledge sharing and guanxi. This suggests that knowledge sharing is likely to occur when trust exists among employees. The results further indicate that norms mediate the relationship between guanxi and knowledge sharing. Guanxi among members influences knowledge sharing; therefore, organizations require a feasible solution using the relational norms mechanism. Previous studies have either emphasized the direct influence of social capital or regarded all variables to be of similar importance for knowledge sharing; however, no clear explanations have been provided explaining its influence on knowledge sharing. We advance understanding of why social capital enhances knowledge sharing among employees and the means by which this occurs.  相似文献

In a previous issue of Knowledge Management Research & Practice (KMRP), we analysed the content and keywords of all articles published in the first decade of KMRP. With this article, we extend our preliminary analysis to the citation and co-citations made by these articles. The study covers all the 256 articles published. The most cited article was A dynamic theory of organisational knowledge creation by Nonaka. The most cited KMRP article was by Nonaka and Toyama: The knowledge-creating theory revisited: knowledge creation as a synthesizing process. The co-citation analysis of the 100 most cited articles in KMRP publications showed that four groups of topics emerged, one around communities and situated learning, the second group around networks, knowledge transfer and research methods, a third group around the foundations of knowledge management and a fourth group around intellectual capital.  相似文献

Ocimum sanctum Linn. (also known as Tulsi) is a sacred Indian plant, the beneficial role of which, in obesity and diabetes is described traditionally. This is a randomized, parallel group, open label pilot study to investigate the effect of O. sanctum on metabolic and biochemical parameters in thirty overweight/obese subjects, divided into two groups A and B. Group A (n = 16) received one 250 mg capsule of Tulsi (O. sanctum) extract twice daily in empty stomach for 8 weeks and group B (n = 14) received no intervention. Statistically significant improvements in the values of serum triglycerides (p = 0.019); low density lipoprotein (p = 0.001); high density lipoprotein (p = 0.001); very low density lipoprotein (p = 0.019); Body Mass Index, BMI (p = 0.005); plasma insulin (p = 0.021) and insulin resistance (p = 0.049) were observed after 8 weeks in the O. sanctum intervention group. The improvement in HDL-C in the intervention group when compared to the control group was also statistically significant (p = 0.037). There was no significant alteration of the liver enzymes SGOT and SGPT in both the intervention (p = 0.141; p = 0.074) and control arms (p = 0.102; p = 0.055) respectively. These observations clearly indicate the beneficial effects of O. sanctum on various biochemical parameters in young overweight/obese subjects.  相似文献

DNA repair capacity is essential in maintaining cellular functions and homeostasis. Identification of genetic polymorphisms responsible for reduced DNA repair capacity may allow better cancer prevention. Double strand break repair pathway plays critical roles in maintaining genome stability. Present study was conducted to determine distribution of XRCC3 Exon 7 (C18067T, rs861539) and XRCC7 Intron 8 (G6721T, rs7003908) gene polymorphisms in North Indian population and compare with different populations globally. The genotype assays were performed in 224 normal healthy individuals of similar ethnicity using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Allelic frequencies of wild type were 79% (C) in XRCC3 Exon 7 C > T and 57% (G) in XRCC7 Intron 8 (G > T) 57% (G) observed. On the other hand, the variant allele frequency were 21% (T) in XRCC3 Exon 7 C > T and 43% (T) in XRCC7 Intron 8 G > T respectively. Major differences from other ethnic populations were observed. Our results suggest that frequency in these DNA repair genes exhibit distinctive pattern in India that could be attributed to ethnicity variation. This could assist in high-risk screening of humans exposed to environmental carcinogens and cancer predisposition in different ethnic groups.  相似文献
