The importance of various work aspects and their organiza tional consequences using Hofstede's cultural dimensions

This study examines the importance employees place on various work aspects according to their nation's relative positioning along Hofstede's four cultural dimension: power distance, individualism, uncertainty avoidance, and masculinity/feminity. Based on a cross-national sample of over 5,000 employees representing 20 countries, the results uncover differential patterns of responses by cultural groupings. The data also suggest that importance and satisfaction interactively affect several organizational consequences critería: job satisfaction, company satisfaction, intent to leave the firm, and organizational cornmitment

The linkages between business strategies and compensation policies using miles and snow's framework

This study links a multidimensional measure of compensatíon strategy to Miles and Snow's (1978) business strategies, and examines their interactive impact on firm performance. The results reported here indicate that a more mechanistic compensation strategy makes a greater contribution to firm performance among defenders, while a more organic compensation strategy makes a greater contribution to firm performance among prospector

The effectiveness of organization-wide compensation strategies in technology intensive firms

This study examines compensation strategies formulated and implemented by high technology firms and their relative effectiveness. Based on a sample of 173 firms, empirical results indicate that the following pay strategies are most appropriate for high technology organizations: A greater emphasis on the individual rather than the job as the unit of analysis, sharing of risks between employees and the firm, an external market orientation, dispersed decision making authority for pay allocation purposes, reliance on aggregate incentives and a longer time orientation

Fundamentos científicos de la rehabilitación tras la sustitución intraarticular del ligamento cruzado anterior

Hay pocos aspectos de la rehabilitación en nuestra especialidad que sean tan complejos y controvertidos como la rehabilitación después de la sustitución intraarticular del ligamento cruzado anterior (LCA). La tendencia actual es utilizar protocolos de rehabilitación acelerada y rápido funcionalismo, todo lo cual está en relación directa con el avance en la investigación sobre el comportamiento biológico de los implantes, una mayor sofisticación en la técnica quirúrgica y los adelantos en las técnicas de rehabilitación. El objetivo de este trabajo es analizar no protocolos concretos, sino los problemas que plantea la cirugía del LCA y como minimizarlos en la medida de lo posible, protegiendo al mismo tiempo la plastia.There are few aspects of rehabilitation in our speciality which are so complex and controversial like rehabilitation after intraarticular replacement of the anterior cruciate ligament (ACL). Nowadays there is a trend to use protocols of accelerated rehabilitation and rapid functioning, and all this is related to the advances in research on the biological behavior of the grafts, a major sophistication in surgical technique and advances in rehabilitation techniques. The objective of this paper is not to analyze concrete protocols but rather the problems that state the surgery of the ACL, and how to diminish them to maximum, protecting at the same time the graft

Reliability of the resonance frequency analysis values in new prototype transepithelial abutments: A prospective clinical study

Resonance frequency analysis (RFA) requires abutment disconnection to monitor implant stability. To overcome this limitation, an experimental transepithelial abutment was designed to allow a SmartPeg to be screwed onto it, in order to determine the prototype abutments repeatability and reproducibility using Osstell ISQ and to assess whether implant length and diameter have an influence on the reliability of these measurements. RFA was conducted with a SmartPeg screwed directly into the implant and onto experimental abutments of different heights of 2, 3.5 and 5 mm. A total of 32 patients (116 implants) were tested. RFA measurements were taken twice for each group from mesial, distal, buccal and palatal/lingual surfaces. Mean values and SD were calculated and Intraclass Correlation Coefficients (ICC) (p < 0.05, IC 95%). The implant stability quotient (ISQ) mean values were 72.581 measured directly to implant and 72.899 (2 mm), 72.391 (3.5 mm) and 71.458 (5 mm) measured from the prototypes. ICC between measurements made directly to implant and through 2-, 3.5-and 5-mm abutments were 0.908, 0.919 and 0.939, respectively. RFA values registered through the experimental transepithelial abutments achieved a high reliability. Neither the implant length nor the diameter had any influence on the measurements’ reliability

Carotenoids from persimmon juice processing

[EN] The aim of this study was the use and revalorization of two persimmon by-products A and B generated in the juice production process. The by-product B resulting from a pectinase enzymatic treatment of peels and pulp to optimize juice extraction was especially suitable for recovery of valuable bioactive carotenoids. The extraction solvents and solvent combinations used were: ethanol, acetone, ethanol/acetone (50:50 v/v) and ethanol/ acetone/hexane (25:25:50 v/v/v). HPLC-DAD analysis detected and identified a total of nine individual carotenoids namely violaxanthin, neoxanthin, antheraxanthin, lutein, zeaxanthin, ß-cryptoxanthin 5,6-epoxide, ß-cryptoxanthin, ¿-carotene, and ß-carotene. ß-cryptoxanthin and ß-carotene represented 49.2% and 13.2% of the total carotenoid content (TCC) in the acetone extract from by-product B. TCC contributed greatly to antioxidant activity of acetone extract derived from this by-product. Pectinase enzymatic treatment of persimmon peels and pulp followed by absolute acetone extraction of carotenoids could be an efficient method to obtain a rich extract in these compounds that could be used as nutraceutical ingredient.This study was supported by Ministerio de Ciencia, Innovacion y Universidades through the funded project 'Simbiosis industrial en el aprovechamiento integral del caqui (Diospyros kaki); Ejemplo de bioeconomia' (CTM2017-88978-R).

Cerebrospinal Fluid Cytokines in Multiple System Atrophy: a Cross-Sectional Catalan MSA Registry Study

Introduction: Neuroinflammation is a potential player in neurodegenerative conditions, particularly the aggressive ones, such as multiple system atrophy (MSA). Previous reports on cytokine levels in MSA using serum or cerebrospinal fluid (CSF) have been inconsistent, including small samples and a limited number of cytokines, often without comparison to Parkinson's disease (PD), a main MSA differential diagnosis. Methods: Cross-sectional study of CSF levels of 38 cytokines using a multiplex assay in 73 participants: 39 MSA patients (19 with parkinsonian type [MSAp], 20 with cerebellar type [MSAc]; 31 probable, 8 possible), 19 PD patients and 15 neurologically unimpaired controls. None of the participants was under non-steroidal anti-inflammatory drugs at the time of the lumbar puncture. Results: There were not significant differences in sex and age among participants. In global non-parametric comparisons FDR-corrected for multiple comparisons, CSF levels of 5 cytokines (FGF-2, IL-10, MCP-3, IL-12p40, MDC) differed among the three groups. In pair-wise FDR-corrected non-parametric comparisons 12 cytokines (FGF-2, eotaxin, fractalkine, IFN-α2, IL-10, MCP-3, IL-12p40, MDC, IL-17, IL-7, MIP-1β, TNF-α) were significantly higher in MSA vs. non-MSA cases (PD + controls pooled together). Of these, MCP-3 and MDC were the most significant ones, also differed in MSA vs. PD, and were significant MSA-predictors in binary logistic regression models and ROC curves adjusted for age. CSF levels of fractalkine and MIP-1α showed a strong and significant positive correlation with UMSARS-2 scores. Conclusion: Increased CSF levels of cytokines such as MCP-3, MDC, fractalkine and MIP-1α deserve consideration as potential diagnostic or severity biomarkers of MSA.info:eu-repo/semantics/publishedVersio
