In this paper we consider a 1-warehouse, N-retailer inventory system where demand occurs at all locations. We introduce an inventory model which allows us to set different service levels for retailers and direct customer demand at the warehouse. For each retailer a critical level is defined, such that a retailer replenishment order is delivered from warehouse stock if and only if the stock level e
This paper investigates the evolution of income inequality in Spain during its transition to democracy, suggesting a method for the correction of under-reporting of earnings and profits in the Household Budget Surveys' data. The contribution is twofold: the methodological proposal, based on income-expenditure discrepancy and scaling-up to National Accounts, improves on previous work and can be use
The polemics of Solomon Adret, Bahya ben Asher, and Abraham Bibago are presented, based on my book: Shield and Sword. 1993.
Thermal stratification is increasing in strength as a result of higher surface water temperature. This could influence the vertical distribution of vertically migrating dinoflagellates. We studied the diel vertical distribution of the dinoflagellates Heterocapsa triquetra and Prorocentrum minimum using stratified laboratory columns with two thermoclines of different strength (Delta TA degrees A =
A comment on [W.J. Olds, A.R. McKinley, M.R. Moore, M.G. Kimlin, In vitro model of vitamin D(3) (cholecalciferol) synthesis by UV radiation: Dose-response relationships, J. Photochem. Photobiol. B: Biol. 93 (2008) 88-93]. The article also discusses some related issues.
Although organizational innovativeness has been regarded as propelling the market, entrepreneurial and learning orientation, as well as innovativeness relationships, much of the evidence to date remains anecdotal and speculative. In other words, little is known empirically about how these orientations contribute to a firm innovation. This leads to reductionism in modeling and thwarts the full expl
Clinically, hemodilution to a hematocrit of 9% has been studied, but the effects of hypovolemia during this degree of hemodilution have not been elucidated. We studied the response to blood loss during extreme hemodilution and evaluated indicators of hypovolemia. Systemic and myocardial hemodynamics, oxygen transport, and blood lactate concentrations were measured in 12 anesthetized pigs exposed t
In 1975, church sanctuary re-emerged in the Netherlands with a new purpose: to protect asylum seekers from deportation. During church sanctuary events, church sanctuary providers host asylum seekers in or around the church building, operating on the understanding that the government will not enter a church to make arrests. The practice is not illegal, but at the same time is not recognized as a ri
Japan continuously attempts to reinterpret war-renouncing Article 9 while at the same time stressing its devotion to pacifism, most recently through the Legislation for Peace and Security. The new Legislation allows Japan to engage in collective self-defense, which was considered unconstitutional for 70 years. This thesis examines Japan’s legitimization of such change, answering the question; how
ABSTRACT Background: Prediabetes is a global epidemic with rising prevalence rates, but its diagnosis based on traditional risk factors is challenging. Application of novel machine-intelligence based methods to public health databases could provide valuable insights into the disease process. Aim: To build predictive models to elucidate the determinants of prediabetes using machine learning algorit
This study is a qualitative case analysis based on fieldwork and multiple semi-structured interviews in Tolima, Colombia. It investigates the community level of the Development Program with a Territorial-based Focus (DPTF) in the south of the department. The program is a result of the peace agreement that was signed between the Colombian government and the guerrilla group the Revolutionary Armed F
The Europeans were confronted with something new and unknown to them when they 'discovered' the Americas. Humanity today is at the verge of establishing a settlement on Mars and being confronted with something new and unknown. This raises the question of what can be learned from history. The working hypothesis of this thesis is that humanity is justifying its right to space with arguments
In this thesis I study international space law’s rules on international responsibility and international liability for private satellite launches. I have used a legal dogmatic method to interpret these rules, before subjecting them to an economic analysis on how they will affect the behaviour of private actors and States. Finally I propose solutions to increase the economic efficiency of three dif
