70-year old female patient with mismatch between hematocrit and hemoglobin values: the effects of cold agglutinin on complete blood count     

?erif Ercan  Mustafa ?al??kan  Erhan Koptur 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(3):391-395

Introduction:

There are a number of pre-analytical and analytical factors, which cause false results in the complete blood count. The present case identifies cold agglutinins as the cause for the mismatch between hematocrit and hemoglobin values.

Materials and methods:

70-year old female patient had a history of cerebrovascular diseases and rheumatoid arthritis. During routine laboratory examination, the patient had normal leukocyte and platelet counts; however, the hemoglobin (Hb: 105 g/L) and hematocrit (HCT: 0.214 L/L) results were discordant. Hemolysis, lipemia and cold agglutinin were evaluated as possible reasons for the mismatch between hematocrit and hemoglobin values.

Results:

First blood sample was slightly hemolysed. Redrawn sample without hemolysis or lipemia was analyzed but the mismatch became even more distinct (Hb: 104 g/L and HCT: 0.08 L/L). In this sample, the titration of the cold agglutinin was determined and found to be positive at 1:64 dilution ratios. After an incubation of the sample at 37°C for 2 hours, reversibility of agglutination was observed.

Conclusion:

We conclude that cold agglutinins may interfere with the analysis of erythrocyte and erythrocyte-related parameters (HCT, MCV, MCH and MCHC); however, Hb, leukocyte and platelet counts are not affected.  相似文献   

Competing Values Framework and its impact on the intellectual capital dimensions: evidence from different Portuguese organizational sectors     

Aristides Isidoro?FerreiraEmail author 《知识管理研究与实践》2014,12(1):86-96

Organizational culture and intellectual capital (IC) have been important topics in the current organizational literature. However, few studies have analysed the correlations between these constructs. From this evidence, the main goal of the present study is to examine the correlation between the perceptions of organizational culture and the perception of IC measures. A sample consisting of 401 workers from the technological, health and services sector responded to the Organizational Culture Assessment Instrument and the Intellectual Capital Scale. Results show that the Competing Values Framework dimensions (clan, adhocracy, hierarchy and market cultures) are correlated with the three IC dimensions studied (customer, structural and human capital). Our results also show that the culture explained variance varies across organizational sectors. The current study provides an initial contribution to the investigation of the correlation between perceived organizational culture and IC measures. The discussion and analysis ends with an integrated framework with practical implications for management, followed by suggestions and guidelines for future studies.  相似文献   

Religious education,communal identity and national politics in the Muslim world   总被引：1，自引：1，他引：0  

Oddbj?rn Leirvik 《British Journal of Religious Education》2004,26(3):223-236

This article discusses models for religious education in school in (parts of) the Muslim world and the implied relation between self and other, confessional and national identity. The question of how current models and discussions respond to globalized issues in education is also discussed. The last part of the article identifies triggering factors behind some recent attempts at establishing more inclusive ways of teaching about religion and ethics in school.  相似文献   

The family caregiver after the institutionalization of the dependent elderly relative     

Macarena Sánchez-Izquierdo Alonso  María Prieto Ursúa  José M Caperos 《Educational gerontology》2017,43(12):650-661

The objective of this study was to assess the relationship between the institutionalization of a dependent elderly relative and the family caregiver’s mental health, quality of life and caregiving satisfaction. We present data from 140 family caregivers caring for elderly family members, of whom 77 continued to live with family members and 63 had been institutionalized. We evaluated the factors influencing the decision to institutionalize the dependent relative, the effect of institutionalization on the caregiver’s psychological well-being and quality of life and the impact of strategies to find the meaning and cope with the relative’s placement on the caregiver’s emotional health and quality of life. Care does not end after institutionalization, but the stressors the caregiver faces change. Our results suggest that finding meaning increases satisfaction and reduces feelings of overload. They show that after institutionalization, stressors affecting caregivers are partly relieved, and that finding meaning increases the caregiver’s satisfaction, while decreasing the degree of overload. Our data, further, indicates that a good relationship and cooperation between the staff of the institution and the family are important to improve the caregivers’ emotional health and quality of life, and consequently, the quality of life of the dependent elderly relative.  相似文献   

CICBS: a methodology and a framework for measuring and managing intellectual capital of cities. A practical application in the city of Mataró     

José María?ViedmaEmail author 《知识管理研究与实践》2004,2(1):13-23

The governments of cities have to make important decisions on the future of their communities. In the past, the vision, objectives, and goals of cities have been determined mainly by considering tangible assets as the main factors of a city's prosperity. However, in the knowledge economy, the role of intangible assets in wealth creation has become fundamental. As a result, a framework of intangible assets that allows navigation from the present reality to the future vision has become an urgent need for all cities. The paper has two well-defined parts. In the first part, it develops a specific methodology and framework for measuring and managing the intellectual capital of cities. In the second part, the study deals with the practical application of this model of intellectual capital in cities with the specific case of the city of Mataró, providing some details of the first cities’ intellectual capital report.  相似文献   

Knowledge sharing in a multi-cultural setting: a case study     

Dianne P?FordEmail author  Yolande E?Chan 《知识管理研究与实践》2003,1(1):11-27

Organizational culture has been shown to influence the success of knowledge management practices. Hofstede's theory specifies that organizational culture is not independent of national culture. A case study of an international subsidiary was conducted to explore the extent to which knowledge sharing is dependent on national culture. Results indicate that language differences can create knowledge blocks, and cross-cultural differences can explain the direction of knowledge flows.  相似文献

Exploring knowledge management implementation in large-sized service organizations – Saudi Arabia as a case     

Sajed M?AbukhaderEmail author 《知识管理研究与实践》2016,14(3):412-421

Whereas there is a growing literature that investigates knowledge management (KM) in service corporates, yet the overview and understanding of KM in large-sized service organisations is yet limited and sparse. Transitional economies, like of Saudi Arabia, are highly motivated to establish a knowledge based structure both economically and socially. There is an urgent need for exploring the current situation of KM tools usage and of perspectives on knowledge and knowledge management, as a start by large sized service organisations. Towards further understanding in this regard, this paper explores the status and potentials of KM implementation scoped to Saudi large-sized service organisations. The paper triangulated an interviewer-administrated questionnaire and focus groups to gather the data. The results indicate that although the weighted average of KM tools/methods deployment (being deployed or can possibly be deployed) reaches 79%; however, the written comments in front of each tool indicates that the participants’ understanding of what KM seems distorted, which is confirmed in the coding of their definitions of the term ‘Knowledge’. The participants identified leadership and strategy formulation as the top two critical success factors. A number of other results are presented and several issues were identified for future research.  相似文献
