The Trouble with Diversifying the Faculty

Author(s): Walter Benn Michaels / Language(s): English / Issue: 1/2012

This article presents the problem of politics of di erence realized within the American educational system, with a special emphasis on higher education. This politics is according to the author based on putting in the center of all educational actions the idea of diversity, as well in creating academic institutions. This key idea becomes in the American context a special significance, regarding the fact that the American society is based on ideology that celebrates multiculturalism and diversity as such. This article presents also an important for the contemporary situation in the United States problem of combining cultural and ethnic diversity on the economical category of di erence between various classes. Furthermore, it seems to be more significant in the light of the economic crisis in recent years that affected also American education in the same extent.

"I'll Think about it Tomorrow": Price Drifts Following Large Pre-Holiday Stock Price Moves

Author(s): Andrey KUDRYAVTSEV / Language(s): English / Issue: 2/2017

The study explores the holiday effect on large daily stock price changes and on subsequent stock returns. The motivation for the study is based on the Mood Maintenance Hypothesis and on the literature documenting lower stock trading activity before holidays. I hypothesize that if a company-specific shock takes place before a holiday, then investors striving to maintain their positive pre-holiday mood, may be less willing to make influential trading decisions, and therefore, may react relatively more weakly to the shock. This kind of behavior may create an underreaction to the shock and result in subsequent price drift. I analyze all major daily stock price moves, defined according to a number of alternative proxies, for all the constituents of S&P 500 Index over the period from 1993 to 2017. I document that both positive and negative stock price moves occurring immediately before public holidays are followed by significant price drifts on the next two (post-holiday) trading days and over five- and twenty-day intervals following the initial price move. The magnitude of these post-event drifts increases over longer time windows. On the other hand, I find that large stock price changes taking place on regular days are followed by either non-significant or marginally significant price reversals. The effect is more pronounced for small and more volatile stocks.

"Лошите кредити": институционални и финансови аспекти, 1994

Author(s): Christina Vutcheva / Language(s): Bulgarian / Publication Year: 1994

Since the beginning of 1991 Bulgaria has been living through a period of transition from centralized totalitarian control to free market economy. Year 1990 can be said to mark the political liberation of the people with the adoption of the new Constitution. The economic liberalization, however, is a reality yet to be brought to life since private ownership is not prevalent in the economy. The prime aim of the transition is to substitute an absurd and inefficient economic system for a new one to rely on the free initiative, private ownership and competition.

(Be)Longing: Coping Among Ageing Filipinas In Valencia, Spain

Author(s): Mari-An Santos,Alvarez Catis / Language(s): English / Publication Year: 0

The Philippines is one of the largest migrant-sending countries in the world. Through their remittances, Filipino migrants sustain their families and the Philippine economy. Much literature has examined the phenomenon from perspectives of families left behind, but their emotional narratives are understudied. From narratives of ageing Filipinas (Filipino women) in Valencia, Spain who have lived there for more than 10 years, using the decolonised methodology of Sikolohiyang Pilipino or SP (Philippine Psychology), this research examines what drives their (be)longing. It is part of a larger study conducted from March to April 2019. The research reveals that the Filipino emotional culture of utang na loob drives coping in two ways: through faith in God within the context of the Catholic church and compassion built within Filipino communities over time. These are only some among a multitude of narratives of searching and finding a semblance of home... away from home. Considering what they contribute to the sending and receiving countries, these emotional narratives must be considered to address the psychosocial needs of migrants now and long after recovery from the global pandemic.

(Hе)научени уроци в процеса на усвояване на средствата от Kохезионния и Cтруктурните фондове на EC

Author(s): Silvia Georgieva / Language(s): Bulgarian / Publication Year: 0

This report examines the errors and omissions of the beneficiaries, which hindered and delayed absorption of operational programs financed by the Cohesion Fund and the Structural Funds of the EU in the first programming period 2007-2013 and reduced the expected effectiveness of the resulting grant resources. These are presented as weaknesses in the preparation of project proposals, as well as irregularities in the implementation phase of projects already approved. At the beginning of the second seven-year planning period analysis of errors and omissions made is necessary to achieve a higher absorption of the agreed resource and noted significant progress in key areas such as economy, health, education, science, employment, environment.

(Local) Wage Settings and (International) Entry Deterrence

Author(s): Domenico Buccella / Language(s): English / Issue: 2/2017

The present paper investigates the use of national wage settings as a mechanism to deter entry via foreign direct investment (FDI) in a unionized monopoly industry. A union which sets centralized wages in a multi-unit firm can both decentralize and change the agenda to prevent the market entry of a non-unionized firm. The adoption of the efficient bargaining agenda is especially effective to deter entry because it lowers the fixed-cost threshold the entrant can bear. Moreover, through side-payments, the incumbent and the union can have common interests in modifying the wage setting to reach outcomes that is Pareto-superior to duopoly. However, if the union cedes “too much power” and becomes “too weak”, internal conflicts with the incumbent firm may arise.

(Re) Integration of Returning Migrants into the Economic Life in Bulgaria

Author(s): Irena Zareva / Language(s): English / Issue: 1/2021

The paper addresses issues related to the impact of external migration on the labour market in Bulgaria, with a focus on returning migrants and their participation in the labour market in the country. The study is based on data from a representative national survey conducted in 2017. Characteristic of the labour status of migrants as a whole and by separate groups is made. A comparative assessment of the employment status before the first departure and after the last return is done. Main problems for the participation of migrants in the labour market in Bulgaria and the need to support their reintegration into the economic life in the country are identified.

105 ANI DE LA PUBLICAREA ÎN ROMÂNIA A PRIMULUI TRATAT DE CALCUL PENTRU ELEMENTELE DE BETON ARMAT

Author(s): George M. CROITORU / Language(s): Romanian / Issue: 1/2020

Reinforced concrete was introduced in Romania since the end of the 19th century by Professor Anghel Saligny (18541925), the most important personality in the history of the Romanian civil engineering. The one who introduces the study of reinforced concrete, through lessons and projects, at the National School of Bridges and Roads in Bucharest, is Professor Ion Ionescu (18701946). Professor Ion Ionescu published the book Reinforced concrete. Elementary exposure of construction rules and calculation principles in May 1915. This is the first book published in the Romanian technical literature which presents material characteristics, execution, quality control, guidelines for structural calculation and examples of calculations for reinforced concrete elements. This technical book has a major historical importance and is a fundamental reference for the evolution and development of the study of reinforced concrete in Romania.

20 Years of European Monetary Policy. From Doctrinarism to Realpolitik 1

Author(s): Luis Ángel Hierro,Antonio José Garzón,Helena Domínguez-Torres / Language(s): English / Issue: Special-2/2019

This paper describes the monetary policy of the European Central Bank since the birth of the Euro. The different economic situations and the monetary policies implemented during the mandate of each one of the three ECB presidents are analysed as a process of evolution. We study the situations of cyclical asynchrony together with the response given to it by the European monetary authority. We also assess the change experienced by the main economic indicators of the twelve founding countries during the 20 years of the single currency. The main conclusion obtained is that monetary policy has evolved from the strict approach defined in the Treaty on the Functioning of the European Union to an approach closer to that of the rest of central banks, which we have called “monetary realpolitik”.

A BAYESIAN INFERENCE OF MULTIPLE STRUCTURAL BREAKS IN MEAN AND ERROR VARIANCE IN PANEL AR (1) MODEL

Author(s): Varun Agiwal,Kumar Jitendra,D. K. Shangodoyin / Language(s): English / Issue: 1/2018

This paper explores the effect of multiple structural breaks to estimate the parameters and test the unit root hypothesis in panel data time series model under Bayesian perspective. These breaks are present in both mean and error variance at the same time point. We obtain Bayes estimates for different loss function using conditional posterior distribution, which is not coming in a closed form, and this is approximately explained by Gibbs sampling. For hypothesis testing, posterior odds ratio is calculated and solved via Monte Carlo Integration. The proposed methodology is illustrated with numerical examples.

A Better Estimator of Population Mean with Power Transformation Based on Ranked Set Sampling

Author(s): Nitu Mehta,V. L. Mandowara / Language(s): English / Issue: 3/2012

Ranked set sampling (RSS) was first suggested by McIntyre (1952) to increase the efficiency of estimate of the population mean. It has been shown that this method is highly beneficial to the estimation based on simple random sampling (SRS). There has been considerable development and many modifications were done on this method. This paper presents a modified ratio estimator using prior value of coefficient of kurtosis of an auxiliary variable x, with the intention to improve the efficiency of ratio estimator in ranked set sampling. The first order approximation to the bias and mean square error (MSE) of the proposed estimator are obtained. A generalized version of the suggested estimator by applying the Power transformation is also presented.

A Bounds Testing Analysis of Migrants Remittances and Financial Development in Selected Sub-Sahara African Countries

Author(s): Taiwo Ajilorea,Sylvanus Ikhider / Language(s): English / Issue: 2/2012

The study investigated the short and long run impact of remittances on financial development, using country-level data on five selected sub-Saharan African countries, which are Cape-Verde, Lesotho, Nigeria, Senegal and Togo. The study utilized the Auto-Regressive Distributed Lag (ARDL) bounds testing approach for testing the existence of co-integration relationships. The study documented the existence of long-run level relationships between remittances and financial development, and documented evidences which show that remittances promote financial development in Cape Verde, Lesotho, Senegal and Togo, but not in Nigeria. The study advocated policies that encourage and facilitate the uninterrupted flow of remittances transfers, adequate institutions, regulatory strengthening and sound macroeconomic policies in the selected countries.

A Class of Chain Ratio-Cum-Dual to Ratio Type Estimator with Two Auxiliary Characters under Double Sampling in Sample Surveys

Author(s): S. Choudhury,B. K. Singh / Language(s): English / Issue: 3/2012

This paper considers a chain ratio-cum-dual to ratio type estimator for estimating population mean of the study variate using two auxiliary variates under double (two-phase) sampling procedure, when the information on another additional auxiliary variate is available along with the main auxiliary variate. The asymptotically optimum estimators (AOEs) in the class are identified in two different cases with their bias and variances. The optimum values of the first phase and second phase sample sizes have been obtained for the fixed cost of survey. Theoretical and empirical studies have also been done to demonstrate the efficiency of the proposed estimator with respect to strategies which utilized the information on two auxiliary variates.

A Class of Product-Type Exponential Estimators of the Population Mean in Simple Random Sampling Scheme

Author(s): A. C. Onyeka / Language(s): English / Issue: 2/2013

The present study proposes a class of product-type exponential estimators for estimating the population mean of the study variable, using known values of some population parameters of an auxiliary character, under the simple random sampling without replacement (SRSWOR) scheme. Furthermore, the study also proposes a modified exponential estimator based on both the ratio-type and the product-type exponential estimators. Properties of the proposed estimators, under the SRSWOR scheme, are obtained up to first order approximation. The modified exponential estimator under optimum conditions is shown to be more efficient than the simple sample mean and the ratio-type and product-type exponential estimators. The theoretical results are supported by an empirical illustration.

A Class of Regression Type Estimators in Survey Sampling

Author(s): Govind Ch. Misra,Subhash K. Yadav,Alok K. Shukla / Language(s): English / Issue: 3/2011

A class of linear regression models has been proposed for the estimation of population mean and total when information regarding auxiliary variate is available in survey sampling using regression method of estimation by introducing a new auxiliary variable z, which may also be a function of the auxiliary variable x. The proposed model leads to reduction in mean squared error as compared to ordinary regression method of estimation. The improvement has been demonstrated over ordinary regression estimator and also on ratio estimator with the help of an empirical example.

A Class of Two Phase Sampling Estimators for Ratio of Two Population Means Using Multi-Auxiliary Characters in the Presence of Non-Response

Author(s): B. B. Khare,R. R. Sinha / Language(s): English / Issue: 3/2014

In this paper, a class of two phase sampling estimators for estimating the ratio of two population means using multi-auxiliary characters with unknown population means has been proposed in presence of non-response. The asymptotic bias, mean square error and minimum mean square error of the proposed class of estimators have been obtained. The optimum values of the sample at the first and the second phases along with the sub-sampling fraction of the non-responding group have been determined for the fixed cost and for the specified precision. The efficiency of the proposed class of estimators has also been shown through the theoretical and empirical studies.
