For Economic Advantage or Something Else? A Case for Racial Identification Switching

The identity choices people take on serve as a filter for viewing the world. It is believed that race identity formation is in part a response to economic and social incentives. Using NELS 1988 dataset we evaluate at the individual level factors that affect changes in self-reported racial identity. We find that being multiracial, living in a non-affirmative action ban state, and relative income/education measures within race groups have an effect on racial identity switching. We find strong evidence that the social-political environments surrounding an affirmative action ban alters the likelihood that an individual will change race. Our results suggest that social factors when present dominate economic incentives to take on a different racial identity.     

Cost-effectiveness analysis in the Spanish setting of the PEAK trial of panitumumab plus mFOLFOX6 compared with bevacizumab plus mFOLFOX6 for first-line treatment of patients with wild-type RAS metastatic colorectal cancer

Objective: To assess the cost-effectiveness of panitumumab in combination with mFOLFOX6 (oxaliplatin, 5-fluorouracil, and leucovorin) vs bevacizumab in combination with mFOLFOX6 as first-line treatment of patients with wild-type RAS metastatic colorectal cancer (mCRC) in Spain.

Methods: A semi-Markov model was developed including the following health states: Progression free; Progressive disease: Treat with best supportive care; Progressive disease: Treat with subsequent active therapy; Attempted resection of metastases; Disease free after metastases resection; Progressive disease: after resection and relapse; and Death. Parametric survival analyses of patient-level progression free survival and overall survival data from the PEAK Phase II clinical trial were used to estimate health state transitions. Additional data from the PEAK trial were considered for the dose and duration of therapy, the use of subsequent therapy, the occurrence of adverse events, and the incidence and probability of time to metastasis resection. Utility weightings were calculated from patient-level data from panitumumab trials evaluating first-, second-, and third-line treatments. The study was performed from the Spanish National Health System (NHS) perspective including only direct costs. A life-time horizon was applied. Probabilistic sensitivity analyses and scenario sensitivity analyses were performed to assess the robustness of the model.

Results: Based on the PEAK trial, which demonstrated greater efficacy of panitumumab vs bevacizumab, both in combination with mFOLFOX6 first-line in wild-type RAS mCRC patients, the estimated incremental cost per life-year gained was €16,567 and the estimated incremental cost per quality-adjusted life year gained was €22,794. The sensitivity analyses showed the model was robust to alternative parameters and assumptions.

Limitations: The analysis was based on a simulation model and, therefore, the results should be interpreted cautiously.

Conclusions: Based on the PEAK Phase II clinical trial and taking into account Spanish costs, the results of the analysis showed that first-line treatment of mCRC with panitumumab?+?mFOLFOX6 could be considered a cost-effective option compared with bevacizumab?+?mFOLFOX6 for the Spanish NHS.     

Propuesta de un índice para evaluar la gestión del control interno

Derived from its humanitarian mission, to pay quality health care to the population, in hospitals and health facilities is needed reduce the occurrence of events that may threaten the physical and psychological integrity of the patients they serve. One of the strategies to consider to overcome this challenge is the proper implementation of the internal control system, to ensure the sustainability of insurers, by increasing efficiency in the care of people, feasible only within a care model that quantifies and management on population identified and addressed. The objective of this paper was to propose a coefficient to evaluate the internal control management for a hospital entity. This was conceived under the guidelines of the multi-criteria modeling in conjunction with the detection of critical points through Petri nets. For this, the order of importance and fulfillment of the components of Internal Control and in unison the unreliability of critical processes in the entity being identified practical application was determined.     

Toward an understanding of online information processing in e-tourism: does national culture matter?

Tourism is undoubtedly among the industries that better reflect the effects of globalization, technological advances (i.e. the Internet) being one of the most relevant drivers. Given the current market saturation of this sector, a better understanding of how tourists from different cultures process online information and forge their attitudes and behavioral intentions is called for. Nevertheless, national culture may have a major influence on the effectiveness of online tourist marketing activities. This study contributes to the extant body of knowledge via the analysis of the influence of perceived risk on how tourists process the information while browsing a tourist destination website, form their attitudes and behavioral intentions toward the destination. The effect of national culture on such antecedents is examined via a cross-cultural research to compare Spanish and British cultures. A theoretical model is proposed to integrate the effect of perceived risk and variables regarding technology acceptance on tourist responses.     

The influence of green practices on supply chain performance: A case study approach

The main objective of this exploratory paper is to investigate the relationships between green practices of supply chain management and supply chain performance. This relationship is investigated in the context of the automotive industry. Five research propositions are suggested and tested with empirical data derived from five case studies taken from the Portuguese automotive supply chain. The data analysis identifies the most important green practices considered by managers, as well as the performance measures that are most appropriate and most widely used as means to evaluate the influence of green practices on supply chain performance. A conceptual model was derived from the data analysis and it can be used to assess the influence of green practices on supply chain performance. This model provides evidence as to which green practices have positive effects on quality, customer satisfaction and efficiency. It also identifies the practices which have negative effects on supply chain performance.     

International Reserves,Effective Demand and Growth

During the last decade, developing (and some developed) economies have accumulated large amounts of international reserves, mainly for precautionary reasons. This phenomenon has been coupled with insufficient economic growth. The resources being amassed largely overwhelm protective needs, there is an excess of resources that is being wasted, and which could be utilised for alternative productive projects, namely to promote growth. If insufficient aggregate demand can largely explain low growth, it is clear that this excess of international reserves can be used to stimulate aggregate demand. This paper argues that the excess of international reserves represents a potential resource to boost growth.     

Foreign direct investment and productivity spillovers: Evidence from the Spanish experience

Foreign Direct Investment and Productivity Spillovers: Evidence from the Spanish Experience. — The aim of this paper is to analyse the impact of foreign direct investment (FDI) on firms’ productivity using a panel of Spanish manufacturing firms for the period 1990–1998. Firstly, we show that for countries, like Spain, that are undergoing significant structural changes over the period in question it is important to control for both time-invariant as well as time-variant sectoral characteristics. Secondly, we confirm previous findings that one needs to take into account the “absorptive capacity” of firms when considering whether they are able to avail of externalities associated with FDI presence. For the Spanish case we find that only firms with sufficient levels of such capacity experience positive spillovers.     

Sharing Wealth: Evidence from Financial Ratios in Spain

Firms are managed on the basis of relationships between mutually involved groups, not only because of market forces, but also due to the influence that each group can exert over distribution decisions at a given moment in time. On the basis of a value added statement, it is possible to analyse the ability a firm has to reward all agents and to consider how the residual income is to be distributed. In this paper we set out to establish the tensions that arise between productive agents in the distribution of generated wealth. We carry out a time analysis of the movements between relationships that provide information on the distribution of that wealth, using data drawn from the Spanish Transport Equipment Manufacturing Industry. We propose a new multivariate dynamic linear model that is capable of analysing the joint evolution of the value added distribution ratios, with our particular objective being to throw light on the factors underlying this evolution. This analysis results in one single factor that explains 92.88 per cent of the total variation present in the residuals of the model.     

Simplified Risk Analysis in Agricultural Extension

Attention is given to the major methods of assessing risk in order to make choices. The literature frequently reports studies on mean-variance (E-V) analysis and stochastic dominance rules. Both of these methods are compared, in an agricultural application, with the approach outlined by Hanoch and Levy. The empirical results suggests that Hanoch and Levy's criterion appear to reduce the size of the risk-efficient set, and that the sets of recommendations from the methods under comparison were consistent. The two recommendations generated by Hanoch and Levy's rule were found to be reasonable for this particular decision process.
