Brief Introduction to Probability Distributions

2014

There is a great deal of uncertainty in any project. That is, data is seldom absolutely reliable and exact, since there is never certainty about duration of tasks, price variations, effect on the environment, etc., to say nothing about those aspects which are external to the project and for which the project developer has no control, such as weather conditions, demand, stock fluctuations, inflation, supplier’s delays, etc. It is believed that many projects are not completed in time and finish with cost overrun, because in their preparation, data is taken as unquestionable, and then actual conditions show that it is not precisely the case. For this reason the uncertainty aspect has to be con…

Shareholder Wealth Effects of Women on Boards Promoting Policies: Evidence from Germany

2017

This study discusses differences in the effectiveness of voluntary and mandatory policies promoting women on boards and their potential effects on stock price returns. Furthermore, it classifies the announcements of the policy proposals discussed in Germany and analyzes their impact using event study methodology. The event date identification follows a two-step procedure employing search engine query data from GoogleTrends and traditional search methods using Lexis-Nexis and newspapers. One key event produces negative significant cumulative abnormal stock returns (CAR) of approximately 1.3 percentage points. Further regression analysis of the CAR reveals that the share of women on the super…

Riemann-Type Definition of the Improper Integrals

2004

Riemann-type definitions of the Riemann improper integral and of the Lebesgue improper integral are obtained from McShane's definition of the Lebesgue integral by imposing a Kurzweil-Henstock's condition on McShane's partitions.

Damping in quantum love affairs

2011

In a series of recent papers we have used an operatorial technique to describe stock markets and, in a different context, {\em love affairs} and their time evolutions. The strategy proposed so far does not allow any dumping effect. In this short note we show how, within the same framework, a strictly non periodic or quasi-periodic effect can be introduced in the model by describing in some details a linear Alice-Bob love relation with damping.

RELEVANCE OF CORPORATE SOCIAL RESPONSIBILITY INDICATORS FOR MEASURING FINANCIAL PERFORMANCE

2013

Clarifying the impact of corporate social responsibility on the economic and/or financial performance of the firm has been the subject of numerous studies, which focus on the nature of the interaction between the ability of companies to achieve a high level of corporate social responsibility on the one hand, and financial performance, on the other. The paper aims to contribute to the literature in this field by studying the relevance of stock exchange indexes built on the principles of corporate social responsibility as a tool to measure the financial performance of firms that adopt corporate social responsibility as manner of approach to business.

The Relationship Between the Comprehensiveness of Corporate Annual Reports and Firm Characteristics in Spain

1994

Abstract Not much information exists in the international accounting literature on Spanish accounting. Spain is selected as a subject of study because it is different from those countries that are subjects of the research concerned with investigating the multivariate impact of firm characteristics on disclosure in annual reports and accounts. The conceptual model underlying our empirical tests is based on economic and political incentives for providing greater detail in corporate annual reports and accounts. The paper provides evidence that the amount of detail in Spanish corporate annual reports and accounts is increasing in firm size and stock exchange listing, and decreasing in liquidity.

Mutations in Romanian Agriculture after De-Collectivization and Privatization

2013

Abstract This paper aims at presenting mutations in agriculture occurred in the process of collectivization and privatization of it. In this paper we analyze the period 1990-2010 following: the dynamics of the use of the land by ownership, the dynamic structure of the value of agricultural production, the dynamic structure of the value of agricultural production and development park tractors and machinery on-farm ownership. In the analyzed period is shown that mutations that occurred in the ownership of the land and other means of production and the system of relations between agriculture and other sectors of the economy have influenced the evolution of the structure of agricultural product…

Relationship between canopy architecture and fruit quality on 'Rich May' peach grafted onto 'Penta' and 'GF677' rootstocks

2006

Observations on crop efficiency and fruit quality of peach trees of ‘Rich May’ grafted onto ‘GF677’ (peach x almond) and ‘Penta’ (Prunus domestica L.) rootstocks are reported. Results were related to canopy architecture parameters, particularly to scaffold branches, shoot and leaf blade inclination angles, to the pattern of light distribution, and to the area of sunflecks projected at midday on the ground. Trees grafted onto ‘GF677’ were more vigorous, in terms of trunk cross-sectional area, summer pruning weight and leaf area. Within canopy light distribution profiles were in agreement with foliage density, with a higher light interception observed in trees grafted on ‘GF677’. Within canop…

Genetic assessment of spatiotemporal evolutionary relationships and stocking effects in grayling (Thymallus thymallus, Salmonidae)

2002

Domestically reared introduced (or escaped) individuals can have detrimental genetic effects on the indigenous populations into which they are released. Consequently, numerous studies have attempted to estimate whether non-native specimens have contributed to the gene pool of wild populations. So far, the key limiting factor of such studies has been their lack of appropriate baseline genetic material. Here, microsatellite DNA analyses of historical scale samples and contemporary wild and introduced populations were used to assess spatiotemporal population structure and stocking effects among endangered Lake Saimaa (eastern Finland) grayling (Thymallus thymallus, Salmonidae). Significant dec…
