A Note on the Regression of Order Statistics

This paper examines the relationships between the mean residual life functions of parallel and k-out-of-n systems with the regression of order statistics. Using these relationships, the results and properties about the mean residual life function of those systems can be used for the regression of order statistics and vice versa. Finally, the paper proposes a definition for the mean residual life function of a k-out-of-n system when the number of failed components of the system is known.     

Posterior Regret Γ-Minimax Estimation and Prediction with Applications on k-Records Data Under Entropy Loss Function

Robust Bayesian analysis is connected with the effect of changing a prior within a class Γ instead of being specified exactly. The multiplicity of prior leads to a collection or a range of Bayes actions. It is interesting not only to investigate the range of estimators but also to recommend the optimal procedures. In this article, we deal with posterior regret Γ-minimax (PRGM) estimation and prediction of an unknown parameter θ and a value of a random variable Y under entropy loss function. Applications for k-records such as estimation and prediction problems are discussed.     

A Bayesian Inference and Stochastic Dynamic Programming Approach to Determine the Best Binomial Distribution

In this research, we employ Bayesian inference and stochastic dynamic programming approaches to select the binomial population with the largest probability of success from n independent Bernoulli populations based upon the sample information. To do this, we first define a probability measure called belief for the event of selecting the best population. Second, we explain the way to model the selection problem using Bayesian inference. Third, we clarify the model by which we improve the beliefs and prove that it converges to select the best population. In this iterative approach, we update the beliefs by taking new observations on the populations under study. This is performed using Bayesian rule and prior beliefs. Fourth, we model the problem of making the decision in a predetermined number of decision stages using the stochastic dynamic programming approach. Finally, in order to understand and to evaluate the proposed methodology, we provide two numerical examples and a comparison study by simulation. The results of the comparison study show that the proposed method performs better than that of Levin and Robbins (1981 Levin , B. , Robbins , H. ( 1981 ).

Comparison among non parametric prediction intervals of order statistics

Abstract

In this article, we are interested in conducting a comparison study between different non parametric prediction intervals of order statistics from a future sample based on an observed order statistics. Typically, coverage probabilities of well-known non parametric prediction intervals may not reach the preassigned probability levels. Moreover, prediction intervals for predicting future order statistics are no longer available in some cases. For this, we propose different methods involving random indices and fractional order statistics. In each case, we find the optimal prediction intervals. Numerical computations are presented to assess the performances of the so-obtained intervals. Finally, a real-life data set is presented and analyzed for illustrative purposes.     

A characterization of stationary renewal processes and of memoryless distributions

We prove first that a renewal process is stationary if and only if the distributions of the age and the residual waiting time coincide for every t>0, and for 0≦x相似文献   

Overseas Foreign Workers in Israel: Policy Aims and Labor Market Outcomes1

The declared aim of the Israeli government, since 1996, was to reduce radically the presence in Israel of foreign overseas workers within five years. This aim has not been achieved due to a counteracting policy: yielding to strong political pressure, the government introduced regulations that virtually indentured legal overseas foreign workers indefinitely to their employers. This depressed their wages and transformed their employment into a source of easy gains, greatly increasing the demand for them and encouraging legal workers to turn illegal. As a result, their numbers have not declined significantly, even though the Israeli economy has been on a downtrend, most of the time, since 1997.     

Group Dynamics in Development of the Poor: Experience from BRAC

The groups deliberately formed by nongovernmental organizations to organize the poor for their development are often subgrouped for better performance. In this connection, the study investigates the extent subgroups contribute to group performance, the mechanisms that lead to the contribution of subgroups to group performance, and changes in the contribution of subgroups to the performance of a group. Altogether 239 Bangladesh Rural Advancement Committee groups, i.e., village organizations (VOs), with and without subgroups were investigated. The VOs with subgroups performed better than those without subgroups. The performance of the VOs with subgroups, however, declined over time. One of the reasons why effectiveness of VOs with subgroups declined was the belief that pursuing subgroup responsibilities would not bring any personal gain for members.

Proletarian Immigrants in Israel, 1948–1961

This study deals with the factors which determined the odds of Israeli immigrants becoming proletariat during the first decade of statehood. It is suggested that the factors which determine whether immigrants enter the proletariat or not are structural. Immigrants trom lesser-developed, non-industrialized countries are more likely than others to become or to remain proletariat. Class positions in the countries of immigration and emigration are compared, and various factors are examined as causes of the proletariat position. Such factors include conditions of production in the country of emigration, level of eduratirin, and year of immigration.     

Immigration,proletarianization, and deproletarianization

Conclusion The strategy of deproletarianization attempted by groups of immigrants of the First and Second Aliyot was determined by the correspondence of three structures: settler capitalism, proletarianization, and ideology. These provided the realm of opportunities from 1882 to 1914. The Great War, which led to the downfall of the Ottoman empire and the establishment of a British administration, then changed the entire economy and politics of Palestine.In this article I divide the studied period into the first and second aliyot. The reader can observe that the correspondence between the above structures was not similar in each sub-period, and that deproletarianization was differently associated with ideology. It was a natural consequence of the immigration motives of the first aliya immigrants, it was not so in the second aliya.The prevailing deteriorating feudalistic mode of production in Palestine made it possible for the immigrants in 1882 and thereafter to establish a settler capitalism. However, the other processes that then occurred were in essence dependent on the socio-economy of the new Yishuv and its relations with the regional market. Proletarianization of immigrants of the first aliya may be considered to have occurred by default. The proto-capitalist system in the Moshavot did not need a Jewish proletariat to survive, because indigenous labor was available and cheap. The immigrants who became day laborers intended to become Ikarim. The economic situation compelled them to search for a solution to their immediate problem of survival. The ideology that prevailed in the motives of these immigrant workers determined to a limited, albeit significant, extent the selection and maintenance of certain forms of deproletarianization over others. In other words, as in many other historical cases, proletarianization was imposed upon individuals who could not maintain their position in the changing socioeconomy. But the first aliya proletariat was distinctive: first, its members were forced to became proletarian through voluntary immigration to a place where their predecessors - with the same background but with the means to purchase tracts of land - had established a protocapitalist sector in the agricultural sector. Second, their proletarianization took the form of day laboring in an expanding agricultural sector, and not as one can observe in Europe, where it was industry that was expanding.Each wave of immigrants brought to Palestine ideological and, to a certain extent, political assets. These had a mediating effect on the forms of adjustment made by the individuals and groups concerned, who, lacking financial capacity, had to choose between re-emigration or proletarianization. Although both waves of immigration developed the intension of alleviating the hardship of their situation, they employed different strategies to accomplish their aims. The first aliya immigrant workers attempted to arrest the process of proletarianization and join the petty bourgeois Ikarim. The second aliya immigrants, in contrast, considered proletarianization as inevitable. But they did not acquiesce to their position. Unlike their predecessors, their resistance was coupled with a peculiar combination of Zionist and socialist motives. This induced the creation of innovative deproletarianization solutions - working-class forms of production and consumption. In essence, deproletarianization was a pursuit of the realization of certain class interests, even though the concrete boundaries of the working class were still obscure. Imported ideology shaped the priorities involved in the selection of the forms of working-class settlements.Proletarianization was forced upon the immigrants not because of a transition from a feudal to capitalist society, as was witnessed at the same period by immigrant Jews to the United States, but rather from feudalism in transition in Russian and Eastern Europe to a retrogressively still more feudalistic system in Palestine. Thus, proletarianization did not result from the disposition and subordination of peasants or artisans by burgeoning capital, (except for a certain category of Arabs) but by the specific instance of an immigrant society encountering lower conditions of production in the country of immigration.The present case study amplifies two related issues. One, that the general law of proletarianization - an inevitable outcome of capitalism- is not to be taken literally. This has already been dealt with in a number of publications on industrialization and proletarianization in nineteenth-century Europe and also the United States. Second, in definite historical circumstances proletarianization may precede the emergence of industrialization, even of proto-industrialization. This is possible, as shown in this case, when immigrants who are motivated by a certain ideology, encounter less developed conditions of production. The deproletarianization strategies discussed here were initiated on the same grounds. One was aimed at integration into the proto-capitalist formation, the other at providing a different route of integration into the country through new forms of colonization.This strategy, still in embryo, marked the future formation of the Jewish working class in Palestine, even though it applied only to a minority of this class. By the creation of a working-class economy and political organizations, this class ensured its survival and development, and, two decades later, its dominance in the Yishuv.
