Journalists' appropriation of ICTs in news-gathering and processing: a case study of Grocott's Mail

Dugo, Habtamu Tesfaye January 2008 (has links)
This study set out to investigate Grocott’s Mail journalists’ appropriation of information and communication technologies in news-gathering and processing using the social shaping of technology as a theoretical lens. It mainly focuses on digital ICTs that journalists use in news-gathering and processing including the Internet, electronic mail, and mobile telephony. Grocott’s Mail is a small-scale newspaper based in Grahamstown, South Africa. Using qualitative research method and the case study as its sub-method, the research reveals that Grocott’s Mail journalists’ appropriation of ICTs involves various opportunities and challenges in news-gathering and processing. In terms of the state of the existing technological infrastructure, the study reveals that since it embraced the digital ICTs in 2003, Grocott’s Mail boasts an adequate ICT infrastructure for a small-scale African newspaper with 30 PCs and one laptop, and professional software for 28 permanent employees. On the other hand, the research reveals serious constraints with the existing ICTs: a huge need for staff training and capacity building to fully utilise the ICTs, and the need to look for ways of raising funds to either upgrade or replace the existing ICTs. Grocott’s Mail journalists use the Internet to do background research on news stories, to verify the accuracy of information, and to check competition across other media. These are the merits of the Internet in news-gathering and processing. On the other hand, there are specific unintended consequences of the Internet such as wasting the company’s working time, and its use leading to lazy/press release journalism. Informants unanimously indicate that the main problems of the Internet are heavy dependence on other online news-sources and wasting time on online entertainment. In terms of using email in news-gathering, the research finds email technology as having advantages such as being a tool of flexibility and speed, a tool for email interviews, and as a technology that promotes participatory journalism. On the other hand, challenges related to email include its limitations because of what interviewees view as its supplementary and small-scale use because of its low contextual richness as opposed to face to face interviews. In terms of cellular telephony, the study finds that regardless of the ubiquity of cell phones and cell phone networks, they have not yet been deployed in news-gathering and processing due to various constraints. These are cell phones not being a big factor in reporting, lack of a proper funding and refunding scheme, prevalence of negative attitudes towards cell phones, and lack of a business model. Thus, cellular phones seem to have little or no relevance in news-gathering and processing at Grocott’s Mail presently.

Využití koní v lesním hospodářství na počátku 21. století

TROJANOVÁ, Denisa January 2017 (has links)
The aim of this diploma thesis was to carry out an analysis of current use of horses in forestry within the South Bohemian region. The diploma thesis contains a brief introduction to the breeding of cold-blooded horses in the Czech Republic, the conditions for breeding cold-blooded horses, the basics of training and harnessing of cold-blooded horses, a description of work done by the horse in a forest and last but not least the thesis presents the issue of causing damage on forest vegetation, soil and soil water while gathering wood. The analysis of common use of horses in forestry has been carried out via the survey method and personal visits. Evaluation and subsequent information analysis was carried out with the focus on the economic side of using horses in forestry and on the estimate of the perspective of their further use. Simplified maps of the South Bohemian Region are a part of the diploma thesis, portraying stables where there are working horses being boarded and capturing possible locations where horses may be used for forestry purposes.

Ponds, rivers and bison freezers : evaluating a behavioral ecological model of hunter-gatherer mobility on Idaho's Snake River Plain

Henrikson, Lael Suzann, 1959- 12 1900 (has links)
xviii, 326 p. : ill. (some col.), maps. A print copy of this title is available through the UO Libraries under the call number: KNIGHT GN799 .F6 H46 2002 / Archaeological evidence indicates that cold storage of bison meat was consistently practiced on the eastern Snake River Plain over the last 8000 years. Recent excavations in three cold lava tube caves have revealed a distinctive artifact assemblage of elk antler tines, broken handstones, and bison bone in association with frozen sagebrush features. Similar evidence has also been discovered in four other caves within the region. A patch choice model was utilized in this study to address how the long-term practice of caching bison meat in cold caves may have functioned in prehistoric subsistence patterns. Because the net return rate for bison was critical to the model, the hunting success of fur trappers occupying the eastern Snake River Plain during the early 1800s, as recorded in their daily journals, was examined and quantified. According to the model, the productivity of cold storage caves must be evaluated against the productivity of other patches on the eastern Snake River Plain, such as ephemeral ponds and linear river corridors from season to season and year to year. The model suggests that residential bases occurred only within river resource patches while ephemeral ponds and ice caves would contain sites indicative of seasonal base camps. The predictions of the model were tested against documented archaeological data from the Snake River Plain through the examination of Geographic Information Systems data provided by the Idaho Bureau of Land Management. The results of this analysis indicate that seasonal base camps are directly associated with both ephemeral and perennial water sources, providing strong support for the model's predictions. Likewise, the temporal distribution of sites within the study area indicates that climate change over the last 8000 years was not dramatic enough to alter long-term subsistence practices in the region. The long-term use of multiple resource patches across the region also confirms that, although the high return rates for bison made them very desirable prey, the over-all diet breadth for the eastern Snake River Plain was broad and included a variety of large and small game and plant foods. Bison and cold storage caves were a single component in a highly mobile seasonal round that persisted for some 8000 years, down to the time of written history in the 19th Century. / Committee in charge: Dr. C.

Paleoethnobotany and household archaeology at the Bergen site : a Middle Holocene occupation in the Fort Rock Basin, Oregon

Helzer, Margaret Mary, 1963- 12 1900 (has links)
xv, 296 p. : ill. (some col.) A print copy of this thesis is available through the UO Libraries under the call number: KNIGHT E78.O6 H44 2001 / This study analyzes the botanical and archaeological material from a Middle Holocene occupation at the Bergen site, located in the Fort Rock Basin, Oregon. It serves to complement and enhance over a decade of research focused on regional settlement patterns in the Northern Great Basin. While previous studies in the region have focused on broadly based settlement patterns, this study shifted the interpretive lens toward an in-depth analysis of a single family dwelling, which was occupied some 6000 years ago. It thus introduces the domain of "household archaeology" into the practice of archaeological research in the Northern Great Basin for the first time. Macrobotanical analysis was conducted on 215 soil samples collected on a 50cm grid from this house. An additional 20 samples were analyzed from a second house structure at the site. These analyses have provided evidence of diet, environment, and social behavior associated with the prehistoric occupants of the house. The abundance of charred bulrush (Scirpus ), goosefoot (Chenopodium ), and waada (Suaeda ) seeds in the deposits indicate that small seeds of wetland-adapted plants were an important dietary resource during the Middle Holocene in the Fort Rock Basin. The patterned distribution of botanical material in 215 soil samples across the floor of the house provide strong evidence of prehistoric human activity areas. The highest concentration of seeds and charcoal in the house was located near the central fire hearth, where cooking and food preparation took place. An east-facing entryway is suggested by the presence of a secondary concentration of seeds and charcoal on the eastern edge of the structure. Analysis also revealed a differential distribution of seed types across the house floor. Higher concentrations of bulrush in the northern area of the floor, away from the hearth, suggest the presence of sleeping mats. Results of this study indicate that plant remains are not evenly distributed through archaeological deposits, therefore care must be taken when sampling for macrobotanical remains. Research at the Bergen site provides the basis for recommendations to assist future archaeologists in determining the best and most cost-effective locations within excavations to take macrobotanical samples. / Committee in charge: Dr. C.

Metsästyksen ongelmapuhe

Karsikas, L. (Leevi) 07 August 2007 (has links)
Abstract In this treatise I will describe and analyse the problematic dialogue about hunting, which, especially after the Second World War has been on the increase. Some of the critics have even demanded that hunting should be stopped altogether. Hunting is criticised and opposed both on ecological and other grounds. These other grounds include religious, philosophical and ethical considerations. The research material includes sociological, anthropological, philosophical and other scientific literature, general literature, newspapers and articles from magazines, video tapes, fairy tales; all that according to the knowledge of sociology is valid information about the society. The applied methods include discursive analysis, tabulation and mathematical models (Boole's algebra) The second chapter focuses on reviewing and analysing literature; its purpose is to point out how the justification of hunting is perceived especially in recent times. In the next three chapters I will analyse the articles published in Helsingin Sanomat in 1992–1996. The sixth chapter focuses on describing the group of criticisers. The background of those critical views will be discussed in conclusions. Hunting can be restricted by ecological premises when the game stock in question would not stand hunting. We are talking about ecological squandering when the spontaneously renewing natural resources, i.e. game, is left unused when people still need to be fed with food that is ecologically more expensive than food obtainable freely from nature e. g. through hunting. Man's own deontological principles require that, when hunted, animals are not tortured or teased. In the beginning, when food was acquired, the prevailing principle was that of ecological primacy principle and total ecology. All food came straight from nature. Nothing was gained by man's own production. Ecological primacy means that part of the food still comes straight from nature, no matter how slight that part may be. Ecological primacy cannot cease to exist because there will always be nature's own yield, available for man as food. If it is not used, it will result in ecological squandering. / Tiivistelmä Tässä tutkimuksessa kuvaillaan ja analysoidaan metsästyksen ongelmapuheita. Niitä on alkanut lisääntyvästi esiintyä toisen maailmansodan jälkeen. Näissä puheissa kritisoidaan metsästystä aina sen lopettamisen vaatimiseen saakka. Metsästystä arvostellaan ja vastustetaan sekä ekologisilla että muilla perusteilla. Näitä muita perusteita ovat uskonnolliset, filosofiset ja eettiset näkökohdat. Tutkimusaineistona on käytetty sosiologista, antropologista, filosofista ja muuta tieteellistä kirjallisuutta, yleistä kirjallisuutta, sanomalehti- ja muita lehtikirjoituksia, videonauhoja, satuja: kaikkea sitä, joka tiedonsosiologian mukaan käy tiedosta yhteiskunnassa. Menetelminä on käytetty diskurssianalyysiä, taulukointia ja matemaattisia malleja (Boolen algebra). Toisessa luvussa selostetaan ja analysoidaan kirjallisuutta ja pyritään osoittamaan, miten metsästyksen oikeutusta mielletään erityisesti viime aikoina. Seuraavissa kolmessa luvussa analysoidaan Helsingin Sanomissa vuosina 1992–1996 julkaistuja kirjoituksia. Kuudennessa luvussa kuvataan arvostelijoiden ryhmää. Johtopäätöksissä pohditaan sitä, miten noihin kriittisiin kannanottoihin on tultu. Metsästys pyritään mitoittamaan ekologisilla perusteilla, niin että kysymyksessä olevan riistaeläimen kanta kestäisi kulloisenkin metsästyksen. Ekotuhlaus taas on kysymyksessä, kun spontaanisti uusiutuvaa luonnonvaraa, riistaa, jätetään käyttämättä, kun ihmisille on kuitenkin tuotettava ruokaa, joka on ekologisesti selvästi kalliimpaa kuin luonnosta vapaasti esimerkiksi metsästämällä saatava ruoka. Ihmisen oma velvollisuusetiikka vaatii, ettei eläimiä niitä metsästettäessä kiduteta eikä kiusata. Alussa vallitsi ruoan hankinnassa suora luonnon käyttö, ekologinen primariteettiperiaate, jossa kaikki ruoka tuli suoraan luonnosta. Mitään ei saatu ihmisen oman tuotannon tuloksena. Se oli ekototalismia, kun ei vielä viljelty kasveja eikä kasvatetettu karjaa. Nykyäänkin osa ruoasta saadaan yhä suoraan luonnosta. Se voi olla kuinka vähäinen osa tahansa. Tämä suora, osittainen luonnon käyttö, ekoprimarismi, ei voi loppua, koska aina on olemassa luonnon spontaania tuottoa, jota ihminen voi käyttää ruokanaan. Jollei sitä käytetä, aiheutetaan siltä osin turhaa viljelyä ja eläinten kasvatusta. Sellainen on ekotuhlausta.

Informationsbeteende i spelskapande : En fallstudie av Paradox Interactive / Information behaviour in game production : A case study of Paradox Interactive

Schlegel, Martin January 2017 (has links)
This thesis focuses on Paradox Interactive's information seeking as a process in the construction of historical computer games. The study is collecting data through a series of interviews with two professional groups: Content designers and 3D graphics. The study focuses on the role of information gathering as a internal process in the creation of the game but also on how the two professions, which have been involved in the study's interviews, gather information relevant to their specific tasks. The study also touches on whether it exists a connection between how Content designers and 3D graphics conduct their searches for information and the ABM sector (that is archives, libraries and museums) as sources/distributors of information. The study has resulted in knowledge regarding the professional groups' information behaviour, what factors that affect the process of gathering information. The study has also resulted in an awareness regarding what kind of information sources that are attractive. Furthermore, the interviews conducted have produced information on how archives, libraries and museums function as information sources for the selected professional groups. The information gathered through the interviews shows that archives, libraries and museums are not used as information sources by the professional groups. Reasons as to why this is the case are a lack of awareness as well as the professional groups' various needs, such as right content and easy accessibility. Games which are utilising or relate to popular history are a clear aspect of modern days popular culture. There exists an abundance of games which relate to history whether they are historical strategy-focused computer games or more action-packed videogames constructed around historical events and contexts. There exists an equally abundance of studies which focuses on games in certain aspects; one such area of research is how history is utilised in games. This study, as noted above, doesn't focus on the games themselves or how they utilise history but rather on the specific question of how the developers gather the information about the past, what sources that exists, and how archives, libraries and museums can better accommodate game creators as a specific group of information gatherers and users.

Detekce metod zjišťujících otisk prohlížeče / Browser Fingerprinting Detection

Saloň, Marek January 2021 (has links)
The main goal of this thesis is to design and implement a mechanism that provides protection against stateless tracking with browser fingerprint. Implemented tool has a form of module that takes part of JavaScript Restrictor extension. The module allows to specify heuristics used for evaluation of visited sites that may contain browser fingerprint extraction. If suspicious activity is detected, all subsequent HTTP requests from that site are blocked to prevent the extracted fingerprint from being sent to the server. The implementation and defined heuristics were tested. The resulting module represents an effective tool against stateless tracking. The main limitation of the implementation is possible corruption of sites by blocking HTTP requests.

Renseignement public et sécurité nationale / Public intelligence and national security

Deprau, Alexis 29 November 2017 (has links)
Si les activités de renseignement public n’étaient pas encadrées, la loi du 24 juillet 2015 relative au renseignement a permis de créer un cadre juridique du renseignement, tout en mettant en avant la communauté du renseignement. Cet encadrement juridique des activités de renseignement s’exerce dans le but de faire face aux menaces à la sécurité nationale. Cet encadrement juridique est aussi une avancée qui a permis d’ériger le renseignement public comme une politique publique, nécessaire pour protéger les intérêts fondamentaux de la Nation, et a été complété par un contrôle concret de ces activités de renseignement. / As the activities of public intelligence services were not regulated before, the law on intelligence dated July 24th, 2015 allowed to create a legal framework of intelligence, while showcasing the intelligence community. This legal framework of intelligence activities is meant to deal with the threats to national security. This legal framework is also a breakthrough allowing to turn public intelligence into public policy, which is required to protect the fundamental interests of the Nation, and it has been completed by an effective control of these intelligence activities.
