La réserve remplit deux fonctions : une fonction politique d’organisation de la société et une fonction sociale de promotion d’un modèle familial et de subsistance. La fonction politique a pour but d’instaurer un ordre politique en affermissant des objectifs politiques et économiques et en assurant la continuité de la cité. Conservation des biens dans la famille, primitivement puis dispersion des biens, aujourd’hui, cette fonction tend à s’effacer au profit de la volonté individuelle du de cujus. La seconde fonction est une fonction sociale, laquelle prend deux visages : la promotion d’un modèle familial et la fourniture d’une subsistance. La réserve s’adapte à notre modèle familial en se limitant à la famille nucléaire. Elle impose également de laisser une subsistance après sa mort, à son héritier réservataire. En droit positif, la fonction de subsistance prend l’ascendant sur la fonction de promotion d’un modèle familial. La nature de la réserve tend à se rapprocher d’une créance. En outre, le développement de cette fonction a conduit le législateur à compléter ou donner de nouveaux droits concurrents à la réserve héréditaire. / The reserved share has two functions : a political function of organization of society and a social function of promoting a family model and a subsitance pattern. The political function’s purpose is to establish a political order by strengthening the political and economic objectives and ensuring the continuity of the city. Safeguarding property in the family, originally then dissipation of assets, today this function tends to disappear in favor of individual freedom of the deceased.The second function is a social function of promoting a family model and providing a subsitance pattern. The reserved share suits to our family model confining itself to the nuclear family. It also requires leaving a subistance after our death, to our forced heir. In positive law, the subsistence function takes the ascendancy on the promoting a family model fonction. The nature of the reserved share tends to resemble to a claim. In addition, the development of this fonction has led the legislator to amplify or to provide new competing rights to the reserved share.

<p>Vi har valt att undersöka hur nyemissioner påverkar aktiekursen. Detta eftersom det den senaste tiden genomförts ett antal nyemissioner på stockholmsbörsen. Undersökningen genomfördes genom en kvantitativ eventstudie av ett antal nyemissioner genomförda på stockholmsbörsen mellan åren 2000-2007. I undersökningen delades de identifierade bolagen upp efter storlek och bransch för att därigenom försöka finna eventuella mönster. För att kunna dra konkreta slutsatser beräknades, med hjälp av ett t-test, konfidensintervall för de olika kategorierna fram. Slutsatsen av undersökningen är att en investerare bör försöka investera då nyemissioner genomförs i stora (Large Cap) bolag och undvika att delta vid nyemissioner i mindre bolag (Small Cap). Vidare bör en investerare speciellt undvika att delta vid nyemissioner inom sällanköpsbranschen.</p> / <p>We have chosen to study whether a new share issue affecting the stock price. This, because of a recently implemented number of new share issues on the Stockholm OMX Exchange. The survey was carried out by a quantitative event study of a number of new share issues on the Stockholm Stock Exchange between the years 2000-2007. The study divided the identified companies down by size and sector in order to try to find any patterns. In order to draw concrete conclusions we´ve calculated, by using a t-test, confidence intervals for the various categories presented. The conclusion of the study is that an investor should invest when new issues are carried out in larger (Large Cap) companies and avoid participating in new issues in smaller companies (Small Cap). In addition, investors also should avoid to participating in new issues in the durable sector.</p>

With the expanding population of Texas and the resulting increase in demand for water, the scarcity of water is becoming an increasingly urgent issue and research is being conducted to find ways to improve water yield, the amount of water that is used for aquifer recharge and riparian areas (lakes, streams, etc). Rangelands provide a major catchment for both surface reservoirs and aquifers. The Edwards Aquifer Recharge Zone and the Twin Buttes Drainage Area were selected to determine the tradeoffs between brush management for increased water yield and wildlife habitat improvement. In April 2002, a mail survey of 300 randomly selected landowners was conducted in each of the two watersheds to gain information regarding their demographics, land cover, and willingness to enter into a cost-share brush removal program. A total of 131 usable questionnaires (43.7%) were returned by Edwards Aquifer area participants, and 141 usable questionnaires (47.0%) were returned by Twin Buttes area participants. Respondents were asked questions including attitudes towards brush amounts and management strategies, and certain constraints that may be included in a cost-share brush removal program. Most respondents indicated interest in enrolling at least part of their land in such a program. Reasoning behind interest varied in each study area. However, interest in various contractual agreements was neutral at best. Policy implications entail considering wildlife habitat mitigation, landowners' preferences, and potential for increasing water yield and determining if all can be managed, or if trade-offs must be considered.

Securities legislation in Canada and around the world does not mandate firms to fulfill announced share repurchase programs. As such, a firms repurchase program completion rate can be interpreted as a measure of the firms voluntary compliance, which communicates to investors the degree to which the firm is responsible, reliable and makes good faith efforts to fulfill its announced programs. We therefore expect that the voluntary compliance may reduce the riskiness of a firm and thus its cost of capital. In a sample of Canadian repurchase programs announced between 1995 and 2004, surprisingly, we find little evidence to suggest that a significant relationship exists between the firms repurchase program completion rate and the cost of equity. We present a number of explanations for this result.

Due to the environmental regulations and acts proposed and initiated by EU, enterprises have to take the impact on the environment into account. As such, they need to standardize suppliers¡¦ production process and management mechanism in their supply chain to lower the impact of their products and production process to the environment. As a result, how to establish suppliers¡¦ awareness of environmental concept and share the knowledge of green product production and related environmental management practices have become the key issue about green supply chain management. This study uses case study method, and seven enterprises which perform well in environmental protection are interviewed. After analysis, there are seven issues are found in this study: 1. Environmental acts in the local markets have positive influence on the implementation of green supply management by global enterprises. 2. The more customization and modularized the product of enterprise is, the more they enhance their green supply management, in order to respond to environmental acts. 3. The emphasis on environmental acts will assist the long-term and cooperative relationship between enterprises and their suppliers. 4. The emphasis on environmental acts will affect positively the collaborative innovation of green supply management. 5. The relationship between enterprises and their suppliers will influence the types of sharing knowledge in green supply management. 5-1. When enterprises and their suppliers have short-term and contractual relationship, they tend to share only explicit knowledge. 5-2. When enterprises and their suppliers have long-term and cooperative relationship, they tend to share explicit and implicit knowledge. 6. The more innovative the products of enterprises, which also have the characteristic of an assembly plant and a system manufacturer in the supply chain, the more likely they play a leading and transferring role in the knowledge sharing of green supply management. 7. The relationship between enterprises and their suppliers, as well as types of shared knowledge, will impact the construction of knowledge sharing and the installation of the controlling (auditing) mechanism of green supply management. 7-1. When enterprises and their suppliers have short-term, contractual relationship, they tend to establish only basic and explicit knowledge sharing mechanism. 7-2. When enterprises and their suppliers have long-term, cooperative relationship, they tend to use more resources and build a comprehensive knowledge sharing mechanism, but have a more restrict controlling (auditing) mechanism as well.

In this thesis, a pass-transistor logic synthesizer is developed for logic mapping of any combinational circuits based on only two types of cells: 2-to-1 multiplexors and inverters. The input contains several sum-of-product Boolean function expressions. Our synthesizer will consider the hardware sharing among these Boolean functions in order to save area. The output of our synthesizer is pass-transistor-based circuits with optimized transistor width in terms of user-specified speed and power performance measurement. During optimization, the Elmore RC delay model is used to estimate the critical path delay and the power is characterized by the switching of all the internal nodes. The final outputs are HSPICE netlists and Verilog gate-level code that allow more detailed timing simulation and automatic placement-routing.

Background: Sustainable development is the buzzword of the decade, yet developing countries struggle to comply with environmental guidelines. A study was done to determine the possibility of financial gain by means of share price prosperity as a result of compliance with environmental accounting principles. Objective: To investigate the relationship between the commitment to environmental accounting principles and the share price of Main Board listed companies on the Johannesburg Stock Exchange. Design: A quantitative, cross-sectional design with descriptive, explanatory and contextual elements was undertaken. Setting and Sample: An all-inclusive sample of the announcements of the Main Board listed companies of the Johannesburg Stock Exchange between 1 June 2008 and 1 June 2013 was used, as well as a stratified random sample of 32 companies – 16 as listed on the SRI Index and 16 not. Measurements: Data related to compliance with environmental accounting principles were correlated with share price fluctuations of Main Board listed companies. T-tests were done to determine whether a correlation exists between compliance with environmental accounting principles and fluctuations in share price. Results: 56 instances of upward trends and 80 instances of downward trends after one month followed announcements that included compliance to environmental accounting principles (one constant and one unknown). 52 instances of upward trends and 54 instances of downward trends after one year followed these announcements (30 unknown). 48 out of 336 listed companies (14%) announce environmental accounting principle compliance with their shareholders. More announcements referring to environmental accounting compliance were posted in 2012 and 2013 (n = 17 and n = 22 averaged for six months) compared to those in 2008 to 2011 (n = 9; n = 15; n = 14 and n = 15 averaged for six months). 56% of companies complying with environmental accounting principles are from the mining industry. 39.19% of principles complied with was within the diverse principle division. P-values derived from t-tests done to investigate correlations between share price and compliance with environmental accounting principles on various levels all revealed P-values of more than 0.25. Conclusions: No statistically significant correlation could be made between compliance with environmental accounting principles and fluctuations in share price. There is low divulgence of compliance practices to shareholders from mentioned companies. An upward trend for compliance with environmental accounting principles is noted during the past five years. The mining industry showed the greatest compliance with these principles when judged according to divulgence of compliance by means of announcements to their shareholders as well as when judged according to stance on the SRI Index. / MBA, North-West University, Potchefstroom Campus, 2014
