A Knowledge Management Process-Based Approach to Support Corporate Crisis Management

In the crisis-prone and complex contemporary business environment, modern organisations and their supply chains, large and small, are challenged by crises more than ever. Knowledge management has been acknowledged as an important discipline able to support the management of complexity in times of crisis. However, the role of effective knowledge retrieval and sharing in the process of crisis prevention, management and survival has been relatively underexplored. In this paper, it is argued that organisational crises create additional challenges for knowledge management, mainly because complex, polymorphic and both structured and unstructured knowledge must be efficiently harnessed, processed and disseminated to the appropriate internal and external supply chain actors, under specific time constraints. In this perspective, a process-based approach is proposed to address the knowledge management needs of organisations during a crisis and to help management in establishing the necessary risk avoidance and recovery mechanisms. Finally, the proposed methodological approach is applied in a knowledge- intensive Greek small and medium enterprise from the pharmaceutical industry, producing empirical results, insights on knowledge pathologies during crises and relevant evaluations.

The most significant deficiencies in macro and micro nutrients in adolescents living with HIV/AIDS in antiretroviral therapy

Objective: To evaluate macro and micronutrients intake of adolescents living with HIV/AIDS in use of antiretroviral therapy and compare it to the Dietary Reference Intakes. Methodology: Cross-sectional study conducted with adolescents of both genders with HIV/AIDS, assessing the dietary composition of macro and micronutrients, using the 24h dietary recall. Results: 39 adolescents, average age of 15 years, 51.3% males. The participants intake of total calories, total fiber (g/d), liposoluble vitamins (A, D, E, K), vitamin B5 (mg/d), vitamin B9 (mg/d), vitamin C (mg/d), calcium (mg/d), phosphorus (mg/d), potassium (mg/d), and magnesium (mg/d) was lower than recommended. The percentages of intake lower than recommended were 79.5% for calories, 82.1% for total fibers, 89.7% for vitamin A, 100% for vitamin D, 87.2% for vitamin E, 100% for vitamin K, 71.8% for vitamin B5, 82.1% for vitamin B9, 76.9% for vitamin C, 92.3% for calcium, 61.5% for phosphorus, 97.4% for potassium, and 76.9% for magnesium. The participants ingested more carbohydrates (g), proteins (g), vitamins B2 (mg/d), B3 (mg/d), B8 (mg/d) and sodium (g/d) than recommended, the percentages above the recommendations being 92.3% for carbohydrates, 64.1% for proteins and vitamin B2, 56.4% for vitamin B3, 82.1% for vitamin B8, and 59% for sodium. The remaining nutrients were within the amounts recommended by the DRIs. Conclusion: Food intake was inadequate as compared to the recommendations of the International Nutrition Guidelines.

Modified Discrete PSO to Increase the Delivered Energy Probability in Distribution energy Systems

This paper proposes a PSO based approach to increase the probability of delivering power to any load point by identifying new investments in distribution energy systems. The statistical failure and repair data of distribution components is the main basis of the proposed methodology that uses a fuzzyprobabilistic modeling for the components outage parameters. The fuzzy membership functions of the outage parameters of each component are based on statistical records. A Modified Discrete PSO optimization model is developed in order to identify the adequate investments in distribution energy system components which allow increasing the probability of delivering power to any customer in the distribution system at the minimum possible cost for the system operator. To illustrate the application of the proposed methodology, the paper includes a case study that considers a 180 bus distribution network.

Real-Time models to predict the use of vasopressors in monitored patients

The needs of reducing human error has been growing in every field of study, and medicine is one of those. Through the implementation of technologies is possible to help in the decision making process of clinics, therefore to reduce the difficulties that are typically faced. This study focuses on easing some of those difficulties by presenting real-time data mining models capable of predicting if a monitored patient, typically admitted in intensive care, will need to take vasopressors. Data Mining models were induced using clinical variables such as vital signs, laboratory analysis, among others. The best model presented a sensitivity of 94.94%. With this model it is possible reducing the misuse of vasopressors acting as prevention. At same time it is offered a better care to patients by anticipating their treatment with vasopressors.

Observations on the dipteran fauna in a focus of dermal leishmaniasis in the State of Minas Gerais: II. The distribution of families in relation to their medical, veterinary and economic importance

Miniature light traps used to collect Phlebotominae in a focus of dermal leishmaniasis in the eastern part of the State of Minas Gerais, Brazil. Over a period of seven months, the other Diptera captured in 179 light trap samples were identified to family level. The traps were placed in eight localities which constituted three different biotopes: three woodland aresas, cultivated land, and a peridomestic site. A comparison is made between the totals of Dipeterans collected in each biotope, the total numbers of families collected in each biotope and the estimated indices of diversity. Dendograms representing the degrees of association between families of Diptera in different biotopes are presented. Some families of Diptera are uniformly distributed throughout the study area; a few families seem to have become adapted to areas where human activity has induced the greatest ecological changes. The impact between Dipterans and human well-being is discussed. The availabel evidence indicates that transmission of dermal leishmaniasis does not occur in areas where sand flies can be captured in greatest densities.

A long-term intake of a protein hydrolysate seems to increase the risk of encephalopathy in mice infected with Schistosoma mansoni

Previous investigations showed that Schistosoma mansoni infection aggravates protein malabsorption in undernourished mice and this can be reverted by administration of casein hydrolysate. The present study was undertaken to evaluate the effects of ingestion of casein hydrolysate for long periods. Albino Swiss mice were divided into eight groups. Diets contained 5% (undernourished ) or 20% (controls) casein levels. For each group there were sub-groups ingesting whole or hydrolysed casein for 12 weeks. Infection with S. mansoni developed in half of the animals under each diet. All undernourished mice developed malabsorption. Low albuminemia was detected in infected animals independently of the protein level in the diet. However, albuminemia was lower in infected controls than in undernourished non-infected mice, suggesting a deficient liver protein synthesis. Infected mice fed on a 20% protein hydrolysed diet exhibited low weight gain and high mortality rates. On the other hand, non-infected mice ingesting the same diet had the highest body weights. We are investigating the hypothesis that infected mice, even when fed normal diets, are unable to metabolise large amounts of amino acids due to the liver lesions related to schistosomiasis and as a result die of hepatic coma. In some of them, the excessive accumulation of ammonia in the blood enhances the outcome of an encephalopathy.

Association between HIV status and HIV knowledge in the population attending Non-Governmental Organizations to perform the rapid HIV test in Catalonia

Human Immunodeficiency Virus continues to be a pandemic. Spain is one of the European countries with the highest incidence of HIV. Within Catalonia, Spain many projects have been implemented with the intention of improving HIV knowledge and lowering the incidence. HIV knowledge is also known to have a positive effect on lowering stigma and discrimination of the people living with HIV. However, few studies study the distribution of HIV knowledge and its association to HIV status, age, sex, geographical zone of origin and level of education within the same study. Objectives: To identify if HIV knowledge is associated with HIV status, age, sex, geographical zone of origin and level of education. Method: Quantitative, cross-sectional, centre-based study comprising of people receiving an HIV test in Catalonia, Spain. Data will be collected from the 11 HIV Non-Governmental Organisations in Catalonia, Spain. The Brief HIV Knowledge Scale will be used to assess HIV knowledge; information from the HIV test session will be used to assess HIV status, age, sex, geographic zone of origin and level of education. The association between HIV knowledge and the afore mentioned variables will then be calculated.

The effectiveness of market intervention policies to improve diet quality and to reduce the prevalence of obesity in Spain

Our project aims at analyzing the relevance of economic factors (mainly income and other socioeconomic characteristics of Spanish households and market prices) on the prevalence of obesity in Spain and to what extent market intervention prices are effective to reduce obesity and improve the quality of the diet, and under what circumstances. In relation to the existing literature worldwide, this project is the first attempt in Spain trying to get an overall picture on the effectiveness of public policies on both food consumption and the quality of diet, on one hand, and on the prevalence of obesity on the other. The project consists of four main parts. The first part represents a critical review of the literature on the economic approach of dealing with the obesity prevalence problems, diet quality and public intervention policies. Although another important body of obesity literature is dealing with physical exercise but in this paper we will limit our attention to those studies related to food consumption respecting the scope of our study and as there are many published literature review dealing with the literature related to the physical exercise and its effect on obesity prevalence. The second part consists of a Parametric and Non-Parametric Analysis of the Role of Economic Factors on Obesity Prevalence in Spain. The third part is trying to overcome the shortcomings of many diet quality indices that have been developed during last decades, such as the Healthy Eating Index, the Diet Quality Index, the Healthy Diet Indicator, and the Mediterranean Diet Score, through the development of a new obesity specific diet quality index. While the last part of our project concentrates on the assessment of the effectiveness of market intervention policies to improve the healthiness of the Spanish Diet Using the new Exact Affine Stone Index (EASI) Demand System.

Validation and performance comparison of two carbon isotope ratio methods to control the misuse of androgens in humans.

Carbon isotope ratio of androgens in urine specimens is routinely determined to exclude an abuse of testosterone or testosterone prohormones by athletes. Increasing application of gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS) in the last years for target and systematic investigations on samples has resulted in the demand for rapid sample throughput as well as high selectivity in the extraction process particularly in the case of conspicuous samples. For that purpose, we present herein the complimentary use of an SPE-based assay and an HPLC fractionation method as a two-stage strategy for the isolation of testosterone metabolites and endogenous reference compounds prior to GC/C/IRMS analyses. Assays validation demonstrated acceptable performance in terms of intermediate precision (range: 0.1-0.4 per thousand) and Bland-Altman analyses revealed no significant bias (0.2 per thousand). For further validation of this two-stage analyses strategy, all the specimens (n=124) collected during a major sport event were processed.

Nurses’ attitudes regarding the importance of families in pediatric nursing care

Affective, cognitive and behavioral components affect nurses´ attitudes to include families in the care processes. The purpose of this study was to investigate the attitudes of nurses about the importance of including families in nursing care. Data collection was performed in pediatric and maternal-child unit of a Brazilian university hospital. A sample of 50 nurses completed the Portuguese version of the instrument Families’Importance in Nursing Care-Nurses’ Attitudes (FINC-NA). The results indicated that nurses have supportive attitudes regarding families participation in nursing care. Attitudes of lower support for involving families in nursing care were found among nurses with older age, more time in the profession and who had no previous contact with contents related to Family Nursing. The application of the instrument in other contexts of assistance may help to illuminate important aspects of the challenges to implementing a family-centered approach in clinical practice.





Beaufils ranges to assess the cotton nutrient status in the southern region of Mato Grosso

The relationships between nutrient contents and indices of the Diagnosis and Recommendation Integrated System (DRIS) are a useful basis to determine appropriate ranges for the interpretation of leaf nutrient contents. The purpose of this study was to establish Beaufils ranges from statistical models of the relationship between foliar concentrations and DRIS indices, generated by two systems of DRIS norms - the F value and natural logarithm transformation - and assess the nutritional status of cotton plants, based on these Beaufils ranges. Yield data from plots (average acreage 100 ha) and foliar concentrations of macro and micronutrients of cotton (Gossypium hirsutum r. latifolium) plants, in the growing season 2004/2005, were stored in a database. The criterion to define the reference population consisted of plots with above-average yields + 0.5 standard deviation (over 4,575 kg ha-1 seed cotton yield). The best-fitting statistical model of the relationship between foliar nutrient concentrations and DRIS indices was linear, with R² > 0.8090, p < 0.01, except for N, with R² = 0.5987, p < 0.01. The two criteria were effective to diagnose the plant nutritional status. The diagnoses were not random, but based on the effectiveness of the chi-square-tested method. The agreement between the methods to assess the nutritional status was 92.59-100 %, except for S, with 74.07 % agreement.
