Information, risk and trust in the food chain : Ex-ante valuation of consumer willingness to pay for beef quality information using the contingent valuation method

The safety of food has become an increasingly interesting issue to consumers and the media. It has also become a source of concern, as the amount of information on the risks related to food safety continues to expand. Today, risk and safety are permanent elements within the concept of food quality. Safety, in particular, is the attribute that consumers find very difficult to assess. The literature in this study consists of three main themes: traceability; consumer behaviour related to both quality and safety issues and perception of risk; and valuation methods. The empirical scope of the study was restricted to beef, because the beef labelling system enables reliable tracing of the origin of beef, as well as attributes related to safety, environmental friendliness and animal welfare. The purpose of this study was to examine what kind of information flows are required to ensure quality and safety in the food chain for beef, and who should produce that information. Studying the willingness to pay of consumers makes it possible to determine whether the consumers consider the quantity of information available on the safety and quality of beef sufficient. One of the main findings of this study was that the majority of Finnish consumers (73%) regard increased quality information as beneficial. These benefits were assessed using the contingent valuation method. The results showed that those who were willing to pay for increased information on the quality and safety of beef would accept an average price increase of 24% per kilogram. The results showed that certain risk factors impact consumer willingness to pay. If the respondents considered genetic modification of food or foodborne zoonotic diseases as harmful or extremely harmful risk factors in food, they were more likely to be willing to pay for quality information. The results produced by the models thus confirmed the premise that certain food-related risks affect willingness to pay for beef quality information. The results also showed that safety-related quality cues are significant to the consumers. In the first place, the consumers would like to receive information on the control of zoonotic diseases that are contagious to humans. Similarly, other process-control related information ranked high among the top responses. Information on any potential genetic modification was also considered important, even though genetic modification was not regarded as a high risk factor.

Leadership and creativity in higher education

Leadership and creativity have received increasing attention from researchers in the field of higher education; however, empirical studies investigating these topics simultaneously are rare. In this study, the authors examined relationships between PhD students' perceptions of their advising professors' passive-avoidant, transactional, and transformational leadership behaviors and professors' ratings of their students' work-related creativity. Data were provided by 71 dyads of professors and PhD students. Consistent with expectations based on the leadership literature on followers' identification with their leaders, results showed that students' perceptions of professors' transformational leadership positively predicted professors' ratings of their students' creativity above and beyond students' perceptions of professors' passive-avoidant and transactional leadership. Contrary to expectations, students' perceptions of professors' passive-avoidant and transactional leadership did not significantly predict professors' ratings of students' creativity. Implications for future research on leadership and creativity as well as tentative practical applications of the findings in higher education settings are discussed.

Coordination and plasticity in leaf anatomical traits of invasive and native vine species

Premise of the study: Plant invasiveness can be promoted by higher values of adaptive traits (e.g., photosynthetic capacity, biomass accumulation), greater plasticity and coordination of these traits, and by higher and positive relative influence of these functionalities on fitness, such as increasing reproductive output. However, the data set for this premise rarely includes linkages between epidermal–stomatal traits, leaf internal anatomy, and physiological performance.• Methods: Three ecological pairs of invasive vs. noninvasive (native) woody vine species of South-East Queensland, Australia were investigated for trait differences in leaf morphology and anatomy under varying light intensity. The linkages of these traits with physiological performance (e.g., water-use efficiency, photosynthesis, and leaf construction cost) and plant adaptive traits of specific leaf area, biomass, and relative growth rates were also explored.• Key results: Except for stomatal size, mean leaf anatomical traits differed significantly between the two groups. Plasticity of traits and, to a very limited extent, their phenotypic integration were higher in the invasive relative to the native species. ANOVA, ordination, and analysis of similarity suggest that for leaf morphology and anatomy, the three functional strategies contribute to the differences between the two groups in the order phenotypic plasticity > trait means > phenotypic integration.• Conclusions: The linkages demonstrated in the study between stomatal complex/gross anatomy and physiology are scarce in the ecological literature of plant invasiveness, but the findings suggest that leaf anatomical traits need to be considered routinely as part of weed species assessment and in the worldwide leaf economic spectrum.

Role of information and communication in redefining unmanned aerial vehicle autonomous control levels

Autonomous mission control, unlike automatic mission control which is generally pre-programmed to execute an intended mission, is guided by the philosophy of carrying out a complete mission on its own through online sensing, information processing, and control reconfiguration. A crucial cornerstone of this philosophy is the capability of intelligence and of information sharing between unmanned aerial vehicles (UAVs) or with a central controller through secured communication links. Though several mission control algorithms, for single and multiple UAVs, have been discussed in the literature, they lack a clear definition of the various autonomous mission control levels. In the conventional system, the ground pilot issues the flight and mission control command to a UAV through a command data link and the UAV transmits intelligence information, back to the ground pilot through a communication link. Thus, the success of the mission depends entirely on the information flow through a secured communication link between ground pilot and the UAV In the past, mission success depended on the continuous interaction of ground pilot with a single UAV, while present day applications are attempting to define mission success through efficient interaction of ground pilot with multiple UAVs. However, the current trend in UAV applications is expected to lead to a futuristic scenario where mission success would depend only on interaction among UAV groups with no interaction with any ground entity. However, to reach this capability level, it is necessary to first understand the various levels of autonomy and the crucial role that information and communication plays in making these autonomy levels possible. This article presents a detailed framework of UAV autonomous mission control levels in the context of information flow and communication between UAVs and UAV groups for each level of autonomy.

Discursive Matrixes of Motherhood : Cultivating Decency and Emotion in Finnish and French Mother-talk

Discursive Matrixes of Motherhood examines women's discourse on their experiences of new motherhood in Finland and France. It sets out from two culturally prevalent turns of speech observed in different social forums: in conversations amongst mothers with tertiary education and in the print media. The pool of data includes: 30 interviews, 8 autobiographically inspired novels and 80 items from women's magazines. With instruments loaned from the toolbox of rhetorical analysis, the recurrence of certain expressions or clichés is analyzed with regard to the national, cultural, biographical, political and daily contexts and settings in which the speaking subjects are immersed. "Staying at home is such a short and special time", the first expression under scrutiny, caught the sociological eye because of its salience in Finland and because it appeared as contradictory with a core characteristic of the Finnish context:long family leave. The cliché was found to function as a discursive micromechanism which swept mothers' 'complaints' under the proverbial carpet. Proper emotions and decency in mother-talk thereby appear as collective achievements. An opposite phenomenon - that of the scaling up of rewards procured by children - was also discerned in the data. Indeed, the French expression "Profiter de mon enfant" ["making the most of my child"/"enjoying my child"] is interpreted as a crystallization of a hedonist ethos of motherhood in everyday language. Secondly, the recurrence of this utterance is analyzed in the light of a requisite located in child-rearing expert literature: that of pleasure that women should take in mothering. Hence, one of the rules found to structure the discursive matrixes of motherhood is the laudability and audibility of enjoyment and conversely the discretion and discouragement of 'complaints'. The cultivation of decent matches between certain categories of emotions and certain categories of individuals also appears as a characteristic of discursive matrixes. One of the methodological findings relates to the fact that such matches may be constituted as sociological objects through the identification of recurrent discursive crystallizations in a given culture. Ideal matches may crystallize in turns of speech and mismatches can be managed through clichés. Becoming a mother entails an immersion in such a particular economy of speech. Key words: mothers, motherhood, transition to parenthood, family, emotions, morality, bonds, rhetorical analysis, discourse analysis, media analysis, France, Finland, comparative sociology

Ways of Explaining Workplace Bullying: A Review of Enabling, Motivating, and Precipitating Structures and Processes in the Work Environment

This paper summarizes literature explaining workplace bullying and focuses on organisational antecedents of bullying. In order to better understand the logic behind bullying, a model discussing different types of explanations is put forward. Thus, explanations for and factors associated with bullying are classified into three groups, i.e. enabling structures or necessary antecedents (e.g. perceived power imbalances, low perceived costs, and dissatisfaction and frustration), motivating structures or incentives (e.g. internal competition, reward systems, and expected benefits), and precipitating processes or triggering circumstances (e.g. downsizing and restructuring, organisational changes, changes in the composition of the workgroup). The paper concludes that bullying is often an interaction between structures and processes from all three groupings.

Essays on Platforms: Business Strategies, Regulation and Policy in Telecommunications, Media and Technology Industries

The growth of the information economy has been stellar in the last decade. General-purpose technologies such as the computer and the Internet have promoted productivity growth in a large number of industries. The effect on telecommunications, media and technology industries has been particularly strong. These industries include mobile telecommunications, printing and publishing, broadcasting, software, hardware and Internet services. There have been large structural changes, which have led to new questions on business strategies, regulation and policy. This thesis focuses on four such questions and answers them by extending the theoretical literature on platforms. The questions (with short answers) are: (i) Do we need to regulate how Internet service providers discriminate between content providers? (Yes.) (ii) What are the welfare effects of allowing consumers to pay to remove advertisements from advertisement-supported products?(Ambiguous, but those watching ads are worse off.) (iii) Why are some markets characterized by open platforms, extendable by third parties, and some by closed platforms, which are not extendable? (It is a trade-off between intensified competition for consumers and benefits from third parties) (iv) Do private platform providers allow third parties to access their platform when it is socially desirable? (No.)

Sukupuoli ja organisaatiot liikkeessä? Gender and Organisations in Flux?

Viimeaikainen sukupuolta ja organisaatiota käsittelevä tutkimus ja kirjallisuus on saanut paljon (toisinaan epäsuoria) vaikutteita feminismiä ympäröivistä keskusteluista. Lisäksi naisten aseman ja kokemuksien tunnistaminen organisaatioissa ja johtamisessa on vaikuttanut tutkimukseen. Erilaisten kansainvälisesti tutkittujen aiheiden kirjo on laaja: sukupuolisuhteet organisaatioiden ja johtoryhmien kulttuureissa ja kommunikaatiossa; sukupuolittunut työnjako; sukupuolittuneet hierarkiat, valta, auktoriteetti ja johtajuus organisaatioissa ja johtamisessa; sukupuolittuneet markkinat; sukupuolittuneet kuvat, symbolit ja mainokset; sukupuoli ja IT teknologia; seksuaalisuus, häirintä, kiusaaminen ja väkivalta organisaatioissa; työn ja kodin yhteensovittaminen; ja niin edelleen. Myös akateemiset organisaatiot sekä niiden sukupuolittuneet valtasuhteet ja johtaminen kaipaavat kipeästi huomiota. Useimpia mainituista alueista on tutkittu ainakin jonkin verran mutta paljon työtä on vielä myös jäljellä. Tämä kokoelma esittelee ajankohtaista suomalaista tutkimusta seuraavista teemoista: tasa-arvo organisaatioissa, naisjohtajuus, yrittäjyyden sukupuoli, verkostot, sukupuolen representaatio sekä sukupuoli ja uusi teknologia. Kokoelma on työryhmän yhdessä koostama joten se on ennen kaikkea yhteistyön tulos. Recent research and literature on the gendering of organisations has been strongly influenced, though sometimes indirectly, by debates in and around feminism, and on recognising women and women’s situations, experiences and voices in organisations and management. The range of topics and issues that have been studied internationally is vast: gender relations in organizational and management groups, cultures and communication; gender divisions of labour; gender divisions of hierarchy, power, authority and leadership in organizations and management; gendered markets; gender imagery, symbols and advertising; gender and information technology; sexuality, harassment, bullying and violence in organisations; home-work relations; and so on. There are also key issues of gender power relations in academic organizations and management themselves, which need urgent attention. Though most of these areas have been researched to some extent, much remains to be done. This collection brings together current Finnish research on: Equality in Organisations, Women in Management, Gender and Entrepreneurship, Networks, Representation of Gender, Gender and ICTs. The book has been put together by an editorial team and is thus first and foremost a collective effort.

Subject Teacher Training and Teaching in English

The purpose of this Master s thesis is on one hand to find out how CLIL (Content and Language Integrated Learning) teachers and English teachers perceive English and its use in teaching, and on the other hand, what they consider important in subject teacher education in English that is being planned and piloted in STEP Project at the University of Helsinki Department of Teacher Education. One research question is also what kind of language requirements teachers think CLIL teachers should have. The research results are viewed in light of previous research and literature on CLIL education. Six teachers participate in this study. Two of them are English teachers in the comprehensive school, two are class teachers in bilingual elementary education, and two are subject teachers in bilingual education, one of whom teaches in a lower secondary school and the other in an upper secondary school. One English teacher and one bilingual class teacher have graduated from a pilot class teacher program in English that started at the University of Helsinki in the middle of the 1990 s. The bilingual subject teachers are not trained in English but they have learned English elsewhere, which is a particular focus of interest in this study because it is expected that a great number of CLIL teachers in Finland do not have actual studies in English philology. The research method is interview and this is a qualitative case study. The interviews are recorded and transcribed for the ease of analysis. The English teachers do not always use English in their lessons and they would not feel confident in teaching another subject completely in English. All of the CLIL teachers trust their English skills in teaching, but the bilingual class teachers also use Finnish during lessons either because some teaching material is in Finnish, or they feel that rules and instructions are understood better in mother tongue or students English skills are not strong enough. One of the bilingual subject teachers is the only one who consciously uses only English in teaching and in discussions with students. Although teachers good English skills are generally considered important, only the teachers who have graduated from the class teacher education in English consider it important that CLIL teachers would have studies in English philology. Regarding the subject teacher education program in English, the respondents hope that its teachers will have strong enough English skills and that it will deliver what it promises. Having student teachers of different subjects studying together is considered beneficial. The results of the study show that acquiring teaching material in English continues to be the teachers own responsibility and a huge burden for the teachers, and there has, in fact, not been much progress in the matter since the beginning of CLIL education. The bilingual subject teachers think, however, that using one s own material can give new inspiration to teaching and enable the use of various pedagogical methods. Although it is questionable if the language competence requirements set for CLIL teachers by the Finnish Ministry of Education are not adhered to, it becomes apparent in the study that studies in English philology do not necessarily guarantee strong enough language skills for CLIL teaching, but teachers own personality and self-confidence have significance.

Systems between information and knowledge : In a memory management model of an extended enterprise

The research question of this thesis was how knowledge can be managed with information systems. Information systems can support but not replace knowledge management. Systems can mainly store epistemic organisational knowledge included in content, and process data and information. Certain value can be achieved by adding communication technology to systems. All communication, however, can not be managed. A new layer between communication and manageable information was named as knowformation. Knowledge management literature was surveyed, together with information species from philosophy, physics, communication theory, and information system science. Positivism, post-positivism, and critical theory were studied, but knowformation in extended organisational memory seemed to be socially constructed. A memory management model of an extended enterprise (M3.exe) and knowformation concept were findings from iterative case studies, covering data, information and knowledge management systems. The cases varied from groups towards extended organisation. Systems were investigated, and administrators, users (knowledge workers) and managers interviewed. The model building required alternative sets of data, information and knowledge, instead of using the traditional pyramid. Also the explicit-tacit dichotomy was reconsidered. As human knowledge is the final aim of all data and information in the systems, the distinction between management of information vs. management of people was harmonised. Information systems were classified as the core of organisational memory. The content of the systems is in practice between communication and presentation. Firstly, the epistemic criterion of knowledge is not required neither in the knowledge management literature, nor from the content of the systems. Secondly, systems deal mostly with containers, and the knowledge management literature with applied knowledge. Also the construction of reality based on the system content and communication supports the knowformation concept. Knowformation belongs to memory management model of an extended enterprise (M3.exe) that is divided into horizontal and vertical key dimensions. Vertically, processes deal with content that can be managed, whereas communication can be supported, mainly by infrastructure. Horizontally, the right hand side of the model contains systems, and the left hand side content, which should be independent from each other. A strategy based on the model was defined.

Opportunity Exploration and Exploitation in International New Ventures: A Study of Relationships’ Involvement in Early Entrepreneurial and Internationalisation Events

International new ventures (INVs) are firms that engage very early after their foundation, if not immediately, in inter-national activities. INVs are a relatively recent phenomenon that deviates from earlier theories on international business. In order to develop our understanding of the emergence and early internationalisation of INVs three different research areas are built upon in the dissertation: International Entrepreneurship, Entrepreneurship and Networks. Net-works have been identified as important for INVs. However, there is a lack of more profound studies regarding the way different types of relationships influence INVs. Few studies are concerned with exploration and exploitation of opportunities and research on the benefits and drawbacks of entrepreneurs’ relationships for the international opportunity recognition process has been called for. By taking a network approach to opportunity exploration and exploitation, the dissertation develops our under-standing of how entrepreneurs’ relationships are involved in exploring and exploiting opportunities during an INV’s early and critical entrepreneurial and internationalisation events. The critical events are studied during three phases: pre-founding, start-up and early internationalisation. Since internationalisation is present from the very beginning, the early internationalisation phase may be parallel to both the pre-founding and the start-up phase. The dissertation contributes to international entrepreneur-ship research in mainly two ways. First, by offering a deep insight into which opportunity exploration and exploitation activities entrepreneurs’ relationships are involved. Second, by adding to our understanding of what the relationships contribute to these activities, mainly in the sense of benefits gained through the relationships. Studying micro firms in real time in their early development towards INVs is considered a unique contribution of the study as it offers valuable insights into pre-founding, start-up, pre-internationalisation as well as early internationalisation. The study shows that in order to understand the development of INVs, it is beneficial to go back to times when there was no thought of starting the INV. By focusing on the entrepreneurs’ background and relationships a more complete picture of the INV is gained. Relationships created at former workplaces or during school time might be the ones that develop business opportunities and set off internationalisation. By focusing on the pre-founding phase, the study also contributes to entrepreneurship literature as this stage has often been neglected or assumed obvious in earlier research. This dissertation shows that an important and mostly lengthy pre-founding phase precedes the decision to start a f rm. In addition, the integration of entrepreneurs’ real experiences with existing theory to develop a continuum for the strength of relationships allows for contributions to network theory.

A Shared European History? Perceptions of Imperialism and Islam in Matriculation Examination Essays and History Textbooks

The European Union (EU) is faced with a continuous decrease in public support. There is a tension between the growing Euroscepticism and the concurrent academic discourse of a shared European identity. Informed and inspired by the current debates, this Master’s Thesis investigates the potential of a shared past to create shared identity. It also addresses the logic of cultural exclusion that is often connected to collective cultural identities. The source material is a combination of exam essays, written as answers to the history tests in the Finnish matriculation examinations of 2005-2008, and upper secondary school history textbooks. From the sources, current perceptions of Islam (as Europe’s Other) and the age of imperialism (as a debated period from Europe’s past) among the youth are studied. Through the analysis the thesis aims to indicate the level of consensus within the pupils’ identification with the past and with Europe. This objective is pursued through examining the pupils’ perceptions of Europe’s past and its relationship to non-European cultures and countries as they are manifested in the essays, and reflecting upon the level of influence that history textbooks as representatives of national hegemonic historical narratives might have on the contents, framings and emphases with and through which the pupils approach, imagine, and reproduce Europe’s past. The approach is based on previous research on the presence of history and the field of textbook research. The theoretical categories with which the sources are analyzed are derived primarily from literature on identity, European integration, history and memory, postcolonial criticism, and theorizations of European identity. Results of the research project suggest that the rhetoric of European superiority, despite its apparent demise, still resonates in contemporary understandings of Europeanness. Dominant perceptions of imperialism comprise of European agency and colonial submission, dominant perceptions of the Islamic world of fundamental difference. Identification with European history among the Finnish youth is rather shallow when examined through perceptions of imperialism; the Islamic world is perceived as Other and its representations are dominated by recent and contemporary international relations.

Investigation on the Potential Rise and Currents in Insulated Mast Scheme with Single Tower During Stroke Interception

The insulated mast scheme for the lightning protection system can be found in a few practical designs. Many advantages over conventional protection system are some times envisaged. However, the technical literature on the analysis of such schemes and further quantification of their protection efficacy is rather scarce. As a first step to address this problem, the present work is taken up and the potential rise at the top and ground end currents in insulating mast scheme with single tower is investigated for several tower heights and pertinent values of other parameters. The quantities that are investigated are the potential difference across the insulation and ground end currents for both tower and the ground wires. Quantifications are carried out for the relevant range of stroke current front times. The influence of number of ground wires, their earthing location and to a limited extent, the length of the insulating support have been ascertained. Some relevant discussion on insulation strength is made. These findings are quite novel and aid in quantification of the practical efficacy of the insulated mast scheme. The level of induction to the support tower and possible flashover to the same are not in favour of this scheme.

Shola habitats on sky islands: status of research on montane forests and grasslands in southern India

The Shola habitat on the high elevation sky islands of the Western Ghats in southern India is a unique habitat. Although this habitat hosts a disproportionately high level of endemism and is threatened by anthropogenic modifications, it has received little research attention. We compiled publications of research conducted in this habitat from scientific databases and the grey literature to examine trends in publication. For a quantitative summary, all publications were classified according to the taxa of research and the broad topic of research. We identified 279 publications from 1964 and found an almost threefold increase in the number of publications and diversity of research topics studied over the last decade. Studies on flora, birds and mammals have been numerous (62% of the studies examined), but certain taxa like fish (1%) have been ignored. Most studies (65%) are descriptive, focusing on diversity, distribution trends and management suggestions, while surprisingly few have concentrated on climate change, ecological restoration and invasive species, all major threats to this landscape. We have identified some key gaps in research and conservation focus that future studies could address. We also suggest that initiatives like edited volumes and special journal sections, along with the use of creative commons licensed data-sharing portals, can be used to usher unpublished work into the public domain.
