Data were collected using Netlytic − an online data mining tool from the social media platforms − and key informant interviews. Findings revealed that stakeholders could be more innovative in their use of social media, but they would be unlikely to do so, without tapping into beneficial interactions of weak ties, as well as fostering strong ties. They also need to utilize the high brokerage role of key facilitating organizations and develop a social media strategy by integrating both ‘online’ and ‘offline’ interactions.","PeriodicalId":43986,"journal":{"name":"Journal of Agricultural & Food Information","volume":"19 1","pages":"331 - 353"},"PeriodicalIF":0.4,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10496505.2018.1430579","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42660999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Connectivity and information flow represent the two key enabling factors for successful operation of the digital farm. These factors also represent the highest vulnerability to cyber-attack to disrupt food production. We introduce a principles-based framework to assess cyber-attack vulnerabilities in the technology itself as well as in the environment to which it is adapted. This provides the elements needed to construct a precision agriculture system protected from cyber-attacks and appropriately matched to the complexity level of the technology in the field.","PeriodicalId":43986,"journal":{"name":"Journal of Agricultural & Food Information","volume":"19 1","pages":"307 - 330"},"PeriodicalIF":0.4,"publicationDate":"2018-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10496505.2017.1417859","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49529280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major constraints to using Facebook were poor network services for farmers and power failure for extension agents. Sex, formal education and income had significant effect on the farmers' level of Facebook use.

The findings indicated that consumers' preference for positively framed symbols was determined by their objective knowledge of genetic modification, education, and income, while preference for negatively framed symbols was influenced by objective knowledge and exposure to food labels.","PeriodicalId":43986,"journal":{"name":"Journal of Agricultural & Food Information","volume":"19 1","pages":"75 - 96"},"PeriodicalIF":0.4,"publicationDate":"2018-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10496505.2017.1369420","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45245498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lauren Manninen profiles Heritage Foods USA, a Brooklyn, New York-based distributor of sustainably produced, heritage-livestock meat products with a mission to preserve endangered species and foods for future generations. Suzi Teghtmeyer explores the fascinating world of hops—an ingredient integral to the production of beer, but having a surprising number of other applications. Peer-reviewed contributions describe various efforts aimed at delivering information to students/youth, farmers, and consumers. With respect to students, Katherine O’Clair and Shane Gillard assess the effectiveness of an online library orientation for undergraduates in the College of Agriculture, Food and Environmental Sciences at California Polytechnic State University. Results from their survey of students’ perceptions and opinions will inform future re-versioning for a more meaningful online learning experience. Grace Troupe, A. McKinzie Peterson, Douglas Golick, Stacie Turnbull, and Don Lee describe their development and use of an online educational resource, The Journey of a Gene, to improve teaching of genetic engineering (GE) concepts to high-school students. Survey and interview findings show promise for the video series in building scientific literacy and addressing reported barriers to effective GE instruction: lack of time and teacher confidence/subject competency. Lastly, Idris Badiru and Temitope Akande report on a novel approach to inspire interest in agriculture among Nigerian youth: the catchy musical recording ‘Cocoa na chocolate,’ released in March 2014 in support of a campaign to promote agricultural investments and improved policies. In the authors’ assessment, the song’s message of “Do Agric, It Pays” falls short in overturning negative perceptions of agriculture as a field with limited opportunity and financial reward. Shifting the focus to farmers, Chrysanthi Charatsari, Alex Koutsouris, Evagelos Lioutas, Apostolos Kalivas, and Eleni Tsaliki share insights from their study of Farmer Field Schools (FFS) as a method of disseminating agricultural information in Greece. They conclude that FFS may be a particularly effective approach, since, in the process of delivering knowledge, they also meet farmers’ social and psychological needs.

These species evolved from natural processes and were selectively bred by farmers over hundreds of animal generations and represent a rich genetic legacy (Sponenberg, Beranger, & Martin, 2014). Each breed possesses unique characteristics, making them suitable to specific environments, farming types, and production purposes. As mainstream agricultural practices industrialized in the last half of the 20th century to focus on high yield, only a few livestock breeds were commercialized—for instance, fast-growing meat producers that could be raised in controlled conditions (Dohner, 2001). The drive for economic viability in an industrialized environment created a turning point for farmers who were faced with a choice: follow the market or continue the trade of generations before. For many years, heritage breeds were abandoned in favor of the higher-yielding breeds; anachronistic heritage breeds became threatened with extinction. There didn’t seem to be a way to raise heritage breeds and maintain farm viability. The Livestock Conservancy’s 2016–2017 Annual Report states that over 150 breeds of livestock are considered to be endangered, some critically, with individual animals numbering in the 100s, on the brink of disappearing forever (Livestock Conservancy, 2017c). Conserving rare breeds of livestock animals is important for many reasons, including biosecurity, disease resistance, genetic diversity, historical significance, supporting family farms and cultural traditions, and providing consumers with varied products (Livestock Conservancy, 2017c). Heritage breeds are bred to be healthy and strong, robust foragers better suited to survival and able to thrive in a changing climate. Kendall (2003) describes instances wheremodern standard breeds may not be the most productive, for instance, in developing countries where controlled environments are not available or in meeting consumer demands for free-range animals. Fortunately, through the help and hard work of groups such as the Livestock Conservancy (https://livestockconservancy.org), numerous breed","PeriodicalId":43986,"journal":{"name":"Journal of Agricultural & Food Information","volume":"19 1","pages":"3 - 8"},"PeriodicalIF":0.4,"publicationDate":"2018-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10496505.2018.1401397","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42612043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
