McDonaldization: an American menace to the Dutch labor market? : research report

The paper considers a (static) portfolio system that satisfies adding-up contraints and the gross substitution theorem. The paper shows the relationship of the two conditions to the weak dominant diagonal property of the matrix of interest rate elasticities. This enables to investigate the impact of simultaneous changes in interest rates on the asset demands.

Non-Commutative Complete Mellin Representation for Feynman Amplitudes

We extend the complete Mellin (CM) representation of Feynman amplitudes to the non-commutative quantum field theories. This representation is a versatile tool. It provides a quick proof of meromorphy of Feynman amplitudes in parameters such as the dimension of space-time. In particular it paves the road for the dimensional renormalization of these theories. This complete Mellin representation also allows the study of asymptotic behavior under rescaling of arbitrary subsets of external invariants of any Feynman amplitude.Comment: 14 pages, no figur

Percolation approach to quark gluon plasma in high energy pp collisions

We apply continuum percolation to proton-proton collisions and look for the possible threshold to phase transition from confined nuclear matter to quark gluon plasma. Making the assumption that J/Psi suppression is a good signal to the transition, we discuss this phenomenon for pp collisions, in the framework of a dual model with strings.Comment: 8 pages, 3 figure

Handover Mechanisms in ATM-based Mobile Systems

This paper presents two handover mechanisms that can be used in the access part of an ATM-based mobile system. The first handover mechanism, which is called ¿handover synchronised switching¿ is relatively simple and does not use any ATM multicasting or resynchronisation in the network. It assumes that there is sufficient time available such that all data and history information of the old path can be transferred to the mobile terminal (MT) before the actual handover to the new path takes place. It is possible that the time between a handover decision and the actual handover is too short to end the transmission on the old path gracefully (e.g., ending the interleaving matrix, ending transcoder functions, emptying intermediate buffers). A possible solution to this problem is given by the second handover mechanism, where multicast connections to all possible target radio systems (RAS) are used in the core network. This mechanism is called ¿handover with multicast support

Stock allocation in general multi-echelon distribution systems with (R, S) order-up-to-policies

In this paper we analyze stock allocation policies in general N-echelon distribution systems, where it is allowed to hold stock at all levels in the network. The goal is to achieve differentiated target customer service levels (fill rates). Various allocation rules and accompanying numerical methods that have already been developed for smaller networks are extended and compared in an extensive numerical experiment. We conclude that the extension of Balanced Stock rationing (see Van der Heijden (1996)) is the most accurate method, in particular in cases of relatively high imbalance. If the imbalance is not too high, the extension of Consistent Appropriate Share rationing (see De Kok et al., 1994; Verrijdt and De Kok, 1996) performs good as well

Comparación entre la gravedad del paciente y la carga de trabajo de la enfermería antes y después de la ocurrencia de eventos adversos en ancianos con cuidados críticos

Indexación: Scopus.Objective: to compare the patient severity and the nursing workload before and after the occurrence of moderate and severe adverse events in elderly hospitalized at intensive care units. Method: comparative study developed at nine intensive therapy units of a University Hospital in São Paulo. The events were collected from the patient histories and classified as moderate and severe according to the World Health Organization. For the severity analysis, the Simplified Acute Physiologic Score II was used and, for the workload analysis, the Nursing Activities Score was applied 24 hours before and after the moderate and severe event. The t-test with 5% significance was used to compare the mean clinical severity and workload scores before and after the event. Results: the sample consisted of 315 elderly, 94 (29.8%) of whom were victims of moderate and severe events at the units. Among the 94 events, the clinical process and procedure type was predominant (40.0%). The installation and maintenance of therapeutic artifacts and catheters were the prevalent interventions that resulted in moderate (76.5%) physiopathological damage (66.0%). The mean workload score (75.19%) dropped 24 hours after the occurrence of the event (71.97%, p=0.008), and the severity, represented by the probability of death, increased from 22.0% to 29.0% after the event (p=0.045). Conclusion: in the patient safety context, the identification of the changes in clinical conditions and the nursing workload in elderly victims of events supports the prevention of these occurrences. © 2018, Universidade Federal de Santa Catarina.

Conclusão: no contexto da segurança do paciente, a identificação das alterações nas condições clínicas e na carga de trabalho de enfermagem em idosos que sofrem eventos subsidiam a prevenção dessas ocorrências.Objetivo: comparar la gravedad del paciente y la carga de trabajo en enfermería antes y después de ocurrir un evento adverso moderado y grave en ancianos internados en unidades de terapia intensiva.

Bond Strength Tests Between Silicon Wafers and Duran Tubes (Fusion Bonded Fluidic Interconnects)

The fusion bond strength of glass tubes with standard silicon wafers is presented. Experiments with plain silicon wafers and those coated with silicon oxide and silicon nitride are presented. Results obtained are discussed in terms of homogeneity and strength of fusion bond. High pressure testing shows that the bond strength is large enough for most applications of fluidic interconnects. The bond strength for 525 /spl mu/m thick silicon with glass tubes having outer diameter of 6 mm and with wall thickness 2 mm, is more than 60 bars after annealing at a temperature of 800/spl deg/C
