The biological and socioeconomic feasibility of restoring elk (Cervus elaphus) to Virginia was assessed. Biological feasibility was determined by evaluating habitat suitability for elk while considering potential impacts of elk on existing fauna and flora in Virginia. Suitability was assessed by creating a habitat suitability index (HSI) model that measured the availability and accessibility of open foraging areas and forested cover areas, the availability of permanent water sources, and the degree of fragmentation by roads. Eight areas were identified as potential elk habitat: 1 in Southwest Virginia, 4 in the Shenandoah Mountains (Shenandoah, Highland, Big Meadows, Peaks of Otter), and 3 in the Southern Piedmont (Danville, Brookneal, Rehobeth). The highest potentials for supporting an elk herd were found in the Highland and Big Meadows study areas, medium biological feasibilities were found in the Southwest, Shenandoah, and Brookneal study areas, and low biological feasibilities were found in the Peaks of Otter, Danville, and Rehobeth study areas. A restored elk herd could negatively affect indigenous fauna and flora by changing the structure and diversity of existing forested ecosystems, but impacts can be minimized by maintaining elk populations at or below cultural carrying capacity. The introduction of diseases during restoration and possible transmission of those diseases from elk to humans, livestock, and other wildlife also are concerns, but these issues can be addressed by following a risk minimization protocol. Socioeconomic feasibility was assessed with a statewide mail survey of Virginia residents, 4 regional stakeholder workshops, an analysis of economic costs and benefits associated with elk restoration, and an assessment of the risks of elk-human conflicts in each of the 8 study areas. Overall, most (61%) respondents agreed that elk restoration would be good for Virginia. However, the low response rate (30%) and low confidence among respondents (49%) in their knowledge about elk indicated that most residents do not have the interest and/or necessary information to form a definitive opinion. Residents believe that the greatest benefits of restoration would be the value-based and indirect ecological benefits, such as returning an extirpated species to its native range, whereas the greatest perceived costs were the economic impacts to property, crop depredation, and public safety hazards. In contrast, local stakeholder representatives identified economic returns from increased tourism due to the presence of elk and the creation of new recreational opportunities as the most anticipated benefits; important concerns were the potential for property damage by elk, the potential impacts on local ecosystems, and the costs of implementing and administering an elk restoration program and subsequent elk management. Proposed resolutions for these issues varied by region. Representatives from the Southwest and northern Shenandoah Mountain (Shenandoah and Big Meadows study site) Regions preferred not to restore elk, whereas those from the southern Shenandoah Mountain (Highland and Peaks of Otter study site) and the Southern Piedmont Regions preferred to start out small with a carefully controlled and monitored "experimental" population. Economic benefits of elk restoration, as determined through analysis of data from other eastern states currently managing elk populations, are associated with tourism and the revenues brought to the community during elk hunting seasons, whereas economic costs are associated with crop damage, elk-vehicle collisions, and the administrative costs of managing an elk herd. Although the initial costs of transporting, releasing, and monitoring a founder population likely will exceed immediate benefits, once an elk population is established, benefits likely will exceed costs. However, an equitable distribution of costs and benefits must be devised so that the individuals who bear the costs are afforded a comparable or greater set of benefits. Risk of landowner elk-conflicts was examined by comparing human population densities and growth rates, percent private versus public land, and agricultural trends across the 8 study areas. Highest risk for elk-human conflicts was identified in the Southern Piedmont Region and in the Shenandoah study site, risk was moderate in the Southwest, Big Meadows, and Peaks of Otter study sites, and risk in the Highland study site was low. Overall, the Highland study site had the highest feasibility for elk restoration of all study areas examined; the Big Meadows and Southwest study sites both demonstrated moderate feasibility. Restoration in these areas is possible so long as management objectives remain flexible, plans are made in advance to address potential concerns, and the public is involved in the decision-making processes both before and after elk are released. / Master of Science

The practice of spamming (sending unsolicited electronic communications) has been dubbed “the scourge of the 21st century” affecting different stakeholders. This practice is also credited for not only disrupting electronic communications but also, it overloads electronic systems and creates unnecessary costs for those affected than the ones responsible for sending such communications. In trying to address this issue nations have implemented anti-spam laws to combat the scourge. South Africa not lagging behind, has put in place anti-spam provisions to deal with the scourge. The anti-spam provisions are scattered in pieces of legislation dealing with diverse issues including: consumer protection; direct marketing; credit laws; and electronic transactions and communications. In addition to these provisions, an Amendment Bill to one of these laws and two Bills covering cybercrimes and cyber-security issues have been published. In this thesis, a question is asked on whether the current fragmented anti-spam provisions are adequate in protecting consumers. Whether the overlaps between these pieces of legislation are competent to deal with the ever increasing threats on electronic communications at large. Finally, the question as to whether a multi-faceted approach, which includes a Model Law on spam would be a suitable starting point setting out requirements for the sending of unsolicited electronic communications can be sufficient in protecting consumers. And as spam is not only a national but also a global problem, South Africa needs to look at the option of entering into mutual agreements with other countries and organisations in order to combat spam at a global level. / Mercantile Law / LL.

Every corporation using IT technologies needs a good and carefully secured network design. The IT security is a key factor of a normal functional of the whole corporation and all its sections. There different methods and concepts for providing different level of IT security. Some of them are very important and should be implemented in every corporate network. There are a lot of services providing inside and outside the corporation network. Increasing the number of services like web services, mail services, file services and other, the number of eventual security issues is rising. The security methods of each of provided services are different and it is required a professional with deep knowledge about this service functionality if it is needed to be good applied. Operation system and application hardering are methods which are not so hard for applying, like configuring proxy server or firewalls, but they could increase the security drastic. In a combination with simple configured security devices, the results could be very impressive. Choosing the right methodology and framework of designing a secured network is important part of entire process. With the right methodology designing could be easier and more effective.

Thesis (LLM)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The monitoring of electronic communication is likely to face all employers sooner or later. The rapid advancement in technology aimed at helping to monitor electronic communication, makes it easier than ever before for employers to monitor the electronic communications of their employees. There are important questions to consider when dealing with the topic of monitoring electronic communication. Examples include "mayan employer legally monitor electronic communications?" and "how does monitoring affect the employee's right to privacy?" This thesis is an attempt to answer these and other related questions by analysing, inter alia, South African legislation, the Constitution and case law, as well as comparing the law as it applies in the United Kingdom and the United States of America. The analysis and conclusion offered in this thesis aim to provide theoretical consideration to academics and practical application for employers that are faced with the reality of monitoring electronic communications. / AFRIKAANSE OPSOMMING: Alle werkgewers sal waarskynlik die een of ander tyd met die monitering van elektroniese kommunikasie gekonfronteer word. Die snelle voortuitgang in tegnologie wat daarop gemik is om te help met die monitering van elektroniese kommunikasie, maak dit vir werkgewers makliker as ooit tevore om sodanige kommunikasies van hulle werknemers te monitor. Daar is egter belangrike vrae wat oorweeg moet word wanneer die onderwerp van monitering van elektroniese kommunikasie ter sprake kom. Voorbeelde hiervan is "mag 'n werknemer regtens elektroniese kommunikasies monitor?" en "hoe raak monitering die werknemer se reg tot privaatheid?" Hierdie tesis is 'n poging om hierdie en ander verwante vrae te beantwoord deur die ontleding van, onder andere, Suid-Afrikaanse wetgewing, die Grondwet en die reg soos deur hofuitsprake ontwikkel, sowel as vergelyking van die reg soos wat dit van toepassing is in die Verenigde Koninkryk en die Verenigde State van Amerika. Die ontleding en gevolgtrekking wat in hierdie tesis aangebied word, is gemik op die verskaffing van teoretiese oorweging aan akademici en praktiese toepassing vir werkgewers wat met die realiteit van die monitering van elektroniese kommunikasies gekonfronteer word.

A nutrition education program for employed women on maintaining a healthy weight was developed and evaluated. Delivery of eight messages (two per week for four weeks) by electronic mail was tested for effectiveness. The subjects were 243 members of the Oregon State University Office and Personnel Association who were randomly assigned to three experimental groups. Group #1 received hard copies of the messages, group #2 received hard copies along with a weekly electronic tip on weight management, and group #3 received the messages by electronic mail (e-mail). An evaluation survey was developed to assess: 1) Participants' stage of change regarding fat in the diet, 2) Participants' social support network for weight maintenance, 3) Reactions to the program, 4) Impact of the program on positive behavior regarding weight control, and 5) Demographics. The survey was sent by campus mail about three weeks after the program. The evaluation was completed by 80.2% of participants. The nine male respondents and the two gender-unidentified respondents were not included in the data analysis to assure a total female population. A total of 181 surveys were analyzed (74.5%). The mean age of female respondents was 47.8 ± 13.3. Although it was hypothesized that electronic delivery of the program and/or supplementing the hard copy/print program with brief electronic tips would be associated with higher order stages of change (Transtheoretical Model), the results from this study did not support the hypotheses. There was no significant difference in stage of change among participants in the three modes of delivery. The messages appeared to have the greatest impact on women in the action and preparation stages. They tended to make more positive changes (i.e. reading food labels) than women in the maintenance, contemplation, and precontemplation stages. Mode of delivery did not appear to make a difference in whether the women looked forward to the messages, reactions to message length, how many were read, or the resulting knowledge or behavior change. Therefore, it may not be critical to program effectiveness. Women in the electronic group, however, were more certain that they received all eight messages and were more apt to ask questions of the researcher. The potential cost savings, convenience, and ease of quick communication make it a more attractive option. Access to the technology and participant preference are equally important factors. / Graduation date: 1997

This study analyses the administrative and economic career of Francesco De Gratta (1613–1676) as Royal Postmaster, Royal Secretary, and trader within the postal and fiscal systems of the Polish-Lithuanian Commonwealth. This investigation focuses mainly on his network and career strategies and is based on various sources from a number of European archives and libraries, mainly those situated in Italy, Poland and Germany. The study presents the family De Gratta and the familial social actions that Francesco used in order to root his children and family in the Polish-Lithuanian noble culture. Next, the analysis shows that the career of Francesco De Gratta was inextricably correlated with the establishment of the early modern royal postal system in Gdańsk (the city of Gdańsk fulfilled an important bridging role within the Poland-Lithuanian Commonwealth) as well as his close contacts with different Polish kings and queens. The career followed distinct stages, tying him ever closer with the Crown, the nobility as well as the merchants in Gdańsk. It all started with his position as Head Postmaster in Gdańsk, in 1654. In 1661, he became Postmaster General of Royal Prussia, Courland, Semigallia and Livonia. After these initial steps, Francesco immersed in creditor activities and close contacts with the Royal Prussian cities, royal authorities, and not the least different Polish mint masters. He also got involved in the potash trade with his later son-in-law Jan Wawrzyniec Wodzicki, first as his factor and later as a co-owner of Wodzicki’s company. The study finally traces his social and economic advancement by the analysis of Francesco De Gratta’s legacies and their importance for his heirs’ social status. The summary compares the career of Francesco De Gratta with that of other postmasters and mint masters of Italian origin in Poland-Lithuania. / Denna studie analyserar Francesco De Grattas (1613-1676) ekonomiska och administrativa karriär som kunglig postmästare, kunglig sekreterare och köpman i det polsk-litauiska samväldet. Denna undersökning är främst inriktad på nätverks- och karriärsanalys och bygger på olika arkivkällor från en rad europeiska arkiv och bibliotek, främst från Italien, Polen och Tyskland. Studien presenterar familjen De Gratta och de familjära sociala strategier som Francesco använde för att förankra sin familj i det polsk-litauiska samväldets adelskultur. Därefter visar analysen att De Grattas karriär kan förstås mot bakgrund av upprättandet av det tidigmoderna kungliga postsystemet i Gdańsk (Gdańsk hade en viktig överbryggande roll inom Polen-Litauen), liksom hans nära kontakter med olika polska kungar och drottningar. Hans karriär följde olika distinkta steg som möjliggjorde för honom att närma sig kronan, adeln och köpmännen i Gdańsk. År 1654 blev han huvudpostmästare i Gdańsk och 1661 fick han ämbetet som huvudpostmästare för Kungliga Preussen, Kurland, Semgallen och Livland. Senare utvecklade Francesco De Gratta sin kreditverksamhet parallellt med utbyggnaden av sitt kontaktnätverk med kungliga preussiska städer, kungliga myndigheter och inte minst olika polska myntmästare. Han blev också involverad i handel med pottaska (kaliumkarbonat) tillsammans med sin svärson Jan Wawrzyniec Wodzicki, först som hans agent och senare som delägare i Wodzickis företag. Slutligen spårar studien Francesco De Grattas sociala och ekonomiska framåtskridande genom en analys av hans arv och dess betydelse för hans arvingars sociala status. Sammanfattningsvis jämförs Francesco De Grattas karriär med andra postmästare och myntmästare av italienskt ursprung i Polen-Litauen. / Information Infrastructure in the Baltic Area.

L’objectif de notre travail était de conduire une étude exploratoire sur la mise en place et le déroulement de la relation matrimoniale au sein de couples philippino-canadiens mariés par correspondance, afin de comprendre les mécanismes sociaux qui régissent l’expérience de vie de ces couples. Nous nous inspirons de Constable pour qui la relation au sein du mariage par correspondance peut être une relation amoureuse même si la logique de désir des deux partenaires est fortement imbriquée dans un contexte historique et culturel. Nous poursuivons la réflexion de Constable sur la relation amoureuse en nous appuyant sur l’analyse de Simmel sur le processus de socialisation entre les individus et le phénomène de l’individualisation au sein des sociétés capitalistes. Nous explorons également comment le couple marié par correspondance crée ce que Kaufmann appelle le contrat amoureux à travers sa correspondance, sa rencontre, son quotidien et son avenir, et comment ce contrat influence les interactions entre les deux membres du couple, ainsi que celles entre le couple et le reste de la société. Dans ce mémoire sur le mariage par correspondance, nous nous intéresserons au quotidien de quatre couples philippino-canadiens mariés par correspondance vivant à Montréal et dans la région, à travers une perspective inspirée du sociologue George Simmel. Nous avons effectué des entretiens, sous forme de récit de vie et utilisé la méthode de l’ethnosociologie pour analyser leur discours. Nos résultats démontrent que le contrat amoureux influence les couples mariés par correspondance au cours des phases successives de leur relation et de leur vie commune. La construction sociale de leur réalité de couple, bâtie sur les sentiments amoureux et le travail au quotidien pour assurer le fonctionnement et la stabilité du couple, permet de passer outre d’éventuelles raisons initiales pratiques pour se marier. Malgré des inégalités, comme la division sexuée du travail et des revenus, l’agentivité de l’épouse est à l’œuvre lors de la planification de la rencontre, la première rencontre physique, l’installation au Canada et l’établissement de la vie commune et le processus de planification du couple. Le contrat amoureux et la construction sociale du couple offrent à l’épouse la possibilité de réduire les inégalités et de gagner une indépendance personnelle. Le retour aux Philippines est important dans la conversation conjugale, notamment au niveau de la planification à long terme du couple. / The aim of this study was to conduct an exploratory research on Filipino-Canadian couples who have met through mail-order bride agencies. In addition, the study explores how those couples formed and ran their marital relationship. This was done in order to understand the social mechanisms that govern the life experience of these couples. We are pursuing Constable’s analysis, which believes that mail-order marriages can be romantic relationships even if the logic of desire of both partners is strongly embedded in a historical and cultural context. Furthermore, Simmel’s analysis on the process of socialization between individuals and the phenomenon of individualization within capitalist societies is used as further evidence to Constable’s analysis. We also explored how the mail-order couple created, what Kaufmann calls the love contract, through their correspondence, their meetings, their daily life and their plans for the future. This contract influenced the interactions between both partners, as well as between the couple and the rest of society. We conducted interviews in the form of life stories with four Filipino-Canadian couples living in the Montreal area (and it’s region) and used the ethnosociology method to analyse those interviews. Our results demonstrate that the love contract influenced the couples during the successive phases of the relationships. The social construction of their reality build on romantic feelings and daily work ensure the stability and the functioning of the couple. This helped them move beyond any initial practical reasons that brought them together. Despite inequalities such as gender, divison of labor and income, the women’s agency is actively present during many of the couple’s steps. For instance, the organization of the first physical meeting of the two spouses, the first meeting, the wife’s immigration to Canada, the daily life in Canada and the planification of the couple’s future all have the wife’s agency present. The love contract and the social construction of the couple offered the possibility, for the wife, to reduce the inequalities in her relationship and help her develop personal independence. Returning to the Philippines was a recurring topic within the couple’s domestic conversation, especially in their long-term planning.
