Values and value conflicts in snack providing of Dutch, Polish, Indonesian and Italian mothers
Full text linkThis study investigates which values play a role in the decision of mothers about snacks to offer to their young children with a focus on the value conflicts that might occur. The study explores whether national culture is reflected in mothers' values in snack choice for their young children and the related value conflicts. Semi-structured interviews with 67 mothers of 2–7 years old children divided over 4 national cultures (Dutch, Polish, Indonesian and Italian) were conducted. Questions were asked about their values and value conflicts when providing a snack to their young children. Four key themes could be distinguished to cluster the mentioned values. The health-related key theme includes all values that are associated with the healthiness of the product, the child-related key theme all values that connects to the child, the time-related key theme includes the value convenience and the product-related key theme includes all values that are associated with the product itself. Dutch and Polish mothers mostly valued health of the snack, whereas Indonesian and Italian mothers mostly valued the preference of their child. Data also shows specific prevalence between values and nationalities: convenience was very important for Dutch mothers, valuing organic food was typical for Polish mothers, religion played a role for Indonesian mothers, while Italian mothers placed more value on brand compared to the mothers of other cultures. In all cultures, the value conflicts mentioned were mainly related to health.</p
Status assessment and roadmap for improvement of food safety management systems in Africa : the case of Tanzania
Full text linkExport oriented food companies in Tanzania are improving their FSMS, but still experience microbiological and chemical safety problems. At local level, food companies continue to experience an increase in the number of cases of foodborne disease outbreaks. Moreover, food safety awareness by the public and market (supermarkets) has increased the demand for quality and safe products accross Africa. Majority of food companies are micro- and small-scale without adequate resources and facilities and operate in poorly regulated environment, which pose a significant challenge to develop more effective FSMS that will reduce incidences of food safety hazards in the agri-food chain. This PhD research attempted to get insights in the FSMS situation in Tanzanian food industries and to develop a roadmap for improvement of current FSMS in order to ensure supply of safe food for both domestic and export markets. The overall objective was to gain an understanding on underlying factors causing insufficient performance of food safety management systems in fish (export oriented) and dairy (domestic market oriented) processing companies in Tanzania in order to develop a roadmap for improvement of these systems.
The specific objectives of the PhD research were (i) to typify the characteristics of food production sectors and food safety legal framework in Tanzania, (ii) to identify the factors contributing to deficiencies in FSMS and the opportunities for improvement of these systems in African food industries, (iii) to determine the current performance status of FSMS and the opportunities for improvement towards more effective FSMS of dairy processing companies, (iv) to determine the current performance status of FSMS and the opportunities for improvement towards more effective FSMS in fish processing companies in Tanzania, (v) to determine the actual microbiological performance of current HACCP-based FSMS in the fishery sector, (vi) to identify the potential causes of the differences in performance of FSMS between the export and local market oriented companies in Tanzania
Food safety management systems in the East African Community : empirical evidence from the fresh produce sector in Kenya and Uganda
Full text linkThus far, few studies concerning production, trade, organization of the supply chain and Food Safety Management Systems (FSMS) for fresh produce, have concentrated specifically on Sub-Saharan African countries, which is exactly the gap in contemporary knowledge this study aims to bridge. The overall objective is to study the modalities and incentives for implementation of Food Safety Management Systems in two East African neighboring countries both at farm and trade level in the fresh produce supply chain.
The scope of the study is the East African Community with specific focus to the green bean and hot pepper chains in Kenya and Uganda respectively in view of their export trends in the global fresh produce market
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
A systematic assessment of quality assurance-based food safety management system of Chinese edible oil manufacturer in view of context characteristics
No full textThis study uses a framework of a food safety management system-diagnostic instrument (FSMS-DI), for the assessment of the context of a Chinese edible oil manufacture through the view of a case study, and an evaluation of the performance of the FSMS of a Chinese edible oil company. The study includes a structured interview with the quality assurance manager. FSMS-DI is used to diagnose the core control and assurance activities, as well as the riskiness of context factors and output of the system. A factory tour is done to verify the information collected during the interview. The company is operating in a low to moderate risk context. The control activities are overall operating at an advanced level, while the assurance activities are at an average level. Although the food safety output of the FSMS is good, improvements are advised on the assurance activities to develop towards a more robust FSMS. This study gives an insight into the current situation of implemented FSMS in view of the context riskiness of the food business. Quantitative studies and further exploration of typical Chinese context characteristics may help food safety authorities, supporting (branch of industry) organisations, and food companies to advance towards a more effective food safety control in the food sector.</p
