Key Factors Influencing Economic Relationships and Communication in Finnish Food Chains

The aim of this report is to discuss the role of the relationship type and communication in two Finnish food chains, namely the pig meat-to-sausage (pig meat chain) and the cereal-to-rye bread (rye chain) chains. Furthermore, the objective is to examine those factors influencing the choice of a relationship type and the sustainability of a business relationship. Altogether 1808 questionnaires were sent to producers, processors and retailers operating in these two chains of which 224 usable questionnaires were returned (the response rate being 12.4%). The great majority of the respondents (98.7%) were small businesses employing less than 50 people. Almost 70 per cent of the respondents were farmers. In both chains, formal contracts were stated to be the most important relationship type used with business partners. Although for many businesses written contracts are a common business practice, the essential role of the contracts was the security they provide regarding the demand/supply and quality issues. Relative to the choice of the relationship types, the main difference between the two chains emerged especially with the prevalence of spot markets and financial participation arrangements. The usage of spot markets was significantly more common in the rye chain when compared to the pig meat chain, while, on the other hand, financial participation arrangements were much more common among the businesses in the pig meat chain than in the rye chain. Furthermore, the analysis showed that most of the businesses in the pig meat chain claimed not to be free to choose the relationship type they use. Especially membership in a co-operative and practices of a business partner were mentioned as the reasons limiting this freedom of choice. The main business relations in both chains were described as having a long-term orientation and being based on formal written contracts. Typical for the main business relationships was also that they are not based on the existence of the key persons only; the relationship would remain even if the key people left the business. The quality of these relationships was satisfactory in both chains and across all the stakeholder groups, though the downstream processors and the retailers had a slightly more positive view on their main business partners than the farmers and the upstream processors. The businesses operating in the pig meat chain seemed also to be more dependent on their main business relations when compared to the businesses in the rye chain. Although the communication means were rather similar in both chains (the phone being the most important), there was some variation between the chains concerning the communication frequency necessary to maintain the relationship with the main business partner. In short, the businesses in the pig meat chain seemed to appreciate more frequent communication with their main business partners when compared to the businesses in the rye chain. Personal meetings with the main business partners were quite rare in both chains. All the respondent groups were, however, fairly satisfied with the communication frequency and information quality between them and the main business partner. The business cultures could be argued to be rather hegemonic among the businesses both in the pig meat and rye chains. Avoidance of uncertainty, appreciation of long-term orientation and independence were considered important factors in the business cultures. Furthermore, trust, commitment and satisfaction in business partners were thought to be essential elements of business operations in all the respondent groups. In order to investigate which factors have an effect on the choice of a relationship type, several hypotheses were tested by using binary and multinomial logit analyses. According to these analyses it could be argued that avoidance of uncertainty and risk has a certain effect on the relationship type chosen, i.e. the willingness to avoid uncertainty increases the probability to choose stable relationships, like repeated market transactions and formal written contracts, but not necessary those, which require high financial commitment (like financial participation arrangements). The probability of engaging in financial participation arrangements seemed to increase with long-term orientation. The hypotheses concerning the sustainability of the economic relations were tested by using structural equation model (SEM). In the model, five variables were found to have a positive and statistically significant impact on the sustainable economic relationship construct. Ordered relative to their importance, those factors are: (i) communication quality, (ii) personal bonds, (iii) equal power distribution, (iv) local embeddedness and (v) competition.

Double time window targeting technique: Real-time DMRG dynamics in the Pariser-Parr-Pople model

We present a generalized adaptive time-dependent density matrix renormalization-group (DMRG) scheme, called the double time window targeting (DTWT) technique, which gives accurate results with nominal computational resources, within reasonable computational time. This procedure originates from the amalgamation of the features of pace keeping DMRG algorithm, first proposed by Luo et al. [Phys. Rev. Lett. 91, 049701 (2003)] and the time-step targeting algorithm by Feiguin and White [Phys. Rev. B 72, 020404 (2005)]. Using the DTWT technique, we study the phenomena of spin-charge separation in conjugated polymers (materials for molecular electronics an spintronics), which have long-range electron-electron interactions and belong to the class of strongly correlated low-dimensional many-body systems. The issue of real-time dynamics within the Pariser-Parr-Pople (PPP) model which includes long-range electron correlations has not been addressed in the literature so far. The present study on PPP chains has revealed that, (i) long-range electron correlations enable both the charge and spin degree of freedom of the electron, to propagate faster in the PPP model compared to Hubbard model, (ii) for standard parameters of the PPP model as applied to conjugated polymers, the charge velocity is almost twice that of the spin velocity, and (iii) the simplistic interpretation of long-range correlations by merely renormalizing the U value of the Hubbard model fails to explain the dynamics of doped holes/electrons in the PPP model.

Human Rights Education in a Finnish Upper Secondary School: Alien Yet Obvious This study focused on conceptions of human rights and human rights education (HRE) among students and teachers. I examined how human rights and HRE are understood by the students and teachers in one general upper secondary school located in southern Finland. I also examined teacher and student discourses about foreigners and immigrants. In the theoretical part of the study I dealt with the history of human rights, the different emphases in HRE and how HRE is handled within the curriculum of upper secondary schools in Finland. In the empirical part of the study I examined HRE in one particular general upper secondary school located in southern Finland where I carried out 28 student interviews and 18 teacher interviews. The study is based on qualitative theme interviews, which I analysed using qualitative content analysis. The aims of HRE as specified in UN documents on education seem not to have been achieved in the Finnish context. The students' knowledge of human rights seemed weak and very limited. Few teachers were familiar with the concept of human rights education. The concept of human rights was also unclear to many of the students. Freedom of speech was the most well-known and the most often-cited human right mentioned in the interviews. Students were not well acquainted with the different human rights instruments or the organisations dealing with human rights. In a way, human rights were both familiar and strange to the students. Materials related to HRE were used very little in the school or not at all. Yet human rights seemed to be very well implemented in the institution. The upper secondary school studied here does not seem to have substantial problems with equality among either the teachers or the students. In the interviews human rights problems were often considered someone else's problem in some other country. The teachers and students connected HRE especially with religious education, history and social studies. Human dignity is mostly dealt with in religious education, while matters concerning the history of human rights are mostly dealt with in history classes. Teachers appear to be human rights educators in the sense that they try to follow human rights principles in their daily work and respect the human dignity of everyone. The special role of a human rights educator was usually assigned to someone else — a teacher or an expert outside the school. HRE was not an intentional or conscious part of teachers´ educational work and was not seen either as belonging to the curriculum or as an obligation prescribed by international documents. There is a need to strengthen the presence of HRE in teacher education. HRE plays an important role in creating a culture of human rights. It is important to implement HRE so that the international aims for HRE will be fulfilled.

Loyalty in Licensing Agreements The purpose of the dissertation is to analyse the impact of the principle of loyalty on licensing agreements from the viewpoint of Finnish law using the traditional legal method (Rechtsdogmatik) combined with empirical data in the form of licensing agreements. The need for good licensing agreements is crucial. One should avoid mechanical and stereotyped agreements in favour of more conscious and goal-oriented ones. When the parties' will and goals have been made clear, the drafting technique should be chosen accordingly. The importance of the principle of loyalty in the interpretation of licensing agreements varies according to their degree of relationality. This is a concept originating in the relational contract theory, more precisely Ian Macneil's spectrum of contracts, where contracts can be placed on an axis according to their degree of relationality. In the dissertation different factors are used to conclude whether the licensing agreement at hand is to be placed on the axis closer to the transactional pole or closer to the relational pole. A conclusion of the dissertation is that few licensing agreements can be placed so close to the transactional pole, that the principle of loyalty lacks importance altogether. The impact of the principle of loyalty the main focus of which is on fostering the contracting parties to behave in accordance with best practices, not for example on altering contract terms is analysed in different situations where the parties' interests typically collide. These situations are discussed from the point of view of three patent and knowhow licensing agreements that differ as to their degree of relationality. A balance needs to be struck between freedom of contract and relational needs. Especially when interpreting more modern licensing agreements, one should not focus on the written document alone, as is often recommended in the literature on Nordic intellectual property law. Neither is the principle of caveat emptor a proper starting point. Moreover, where the parties are of equal bargaining power, one should not assume that the grants in licensing agreements are to be interpreted narrowly. Focus in the interpretation should instead be on the entirety of the circumstances.

"Ei sitä ainakaan helpommaksi tehdä sairaan opiskelijan elämää" : Pitkäaikaissairaiden kokemuksia korkeakoulutuksen esteistä ja mahdollisuuksista

This study examines the experiences of students with chronic illnesses in higher education. I chose to study rheumatic and other musculoskeletal diseases because they are group of diseases that are nationally significant in Finland. From students experiences I do interpretation of their agency. My research problems are: What kind of obstacles and possibilities student with chronic illness experiences in studying? What kind of obstacles illness set up for the agency or does it set any? How agency of student with chronic illness shows in the context of the university? I collected the data by using interview and focus group method. Additionally I had different kinds of documents of accessibility and equality in the university. Interviews were like halfstructured theme and open interviews. Focus group method I have applied. All the people that participated in the study were students from the university of Helsinki. They all have rheumatic or other musculoskeletal diseases. I have five interviewees and the group consisted of two people and the researcher. In the data analysis I use categorizing by the themes. Students that participated in my study spoke about their pain related experiences of their illness which also connected to their experiences of the higher education. Students agencies were limited the more they experienced pain. Pain forces students to certain activity one actions avoidance and another s favouring. If part-time studying would have been possible economically, it would have made the life easier for a part of the students. Students were aware of the available resources of their body for some of the students illness and life control set challenge and for some it set conditions. Students thought that university education is more possible to them than vocational education. Students didn t feel their own body limited in the context of university that emphasize intellectual and knowledge connected values and some of the students had reversed their illness as a resource of studying. However students felt their illness as a private matter and they considered illness profit and disadvantage before telling about it, which I interpretated limiting students agencies. In the university terms of students agencies were bond to individuality that came up in positive and negative. Freedom of studying was positive but official and individual study accommodations made agency bounded. Majority of the students didn t see possibilities to do differently in the university s practice but some of the students had recognised values underneath the practices that made it possible to reflect them, do differently and made space for agency.

From Habits to Social Structures : Pragmatism and Contemporary Social Theory

Pragmatism has sometimes been taken as a catchphrase for epistemological stances in which anything goes. However, other authors argue that the real novelty and contribution of this tradition has to do with its view of action as the context in which all things human take place. Thus, it is action rather than, for example, discourses that should be our starting point in social theory. The introductory section of the book situates pragmatism (especially the ideas of G. H. Mead and John Dewey) within the field and tradition of social theory. This introductory also contextualizes the main core of the book which consists of four chapters. Two of these chapters have been published as articles in scientific journals and one in an edited book. All of them discuss the core problem of social theory: how is action related to social structures (and vice versa)? The argument is that habitual action is the explanation for the emergence of social structures from our action. Action produces structures and social reproduction takes place when action is habitualized; that is, when we develop social dispositions to act in a certain manner in familiar environments. This also means that even though the physical environment is the same for all of us, our habits structure it into different kinds of action possibilities. Each chapter highlights these general insights from different angles. Practice theory has gained momentum in recent years and it has many commonalities with pragmatism because both highlight the situated and corporeal character of human activity. One famous proponent of practice theory is Margaret Archer who has argued that the pragmatism of G. H. Mead leads to an oversocialized conception of selfhood. Mead does indeed present a socialized view of selfhood but this is a meta-sociological argument rather than a substantial sociological claim. Accordingly, one can argue that in this general sense intersubjectivity precedes subjectivity and not the other way around. Such a view does not indicate that our social relation would necessarily "colonize" individual action because there is a place for internal conversations (in Archer s terminology); it is especially in those phases of action where it meets obstacles due to the changes of the environment. The second issue discussed has the background assumption that social structures can fruitfully be conceptualized as institutions. A general classification of different institution theories is presented and it is argued that there is a need for a habitual theory of institutions due to the problems associated with these other theories. So-called habitual institutionalism accounts for institutions in terms of established and prevalent social dispositions that structure our social interactions. The germs of this institution theory can be found in the work of Thorstein Veblen. Since Veblen s times, these ideas have been discussed for example, by the economist Geoffrey M. Hodgson. His ideas on the evolution of institutions are presented but a critical stance is taken towards his tendency of defining institutions with the help of rules because rules are not always present in institutions. Accordingly, habitual action is the most basic but by no means the only aspect of institutional reproduction. The third chapter deals with theme of action and structures in the context of Pierre Bourdieu s thought. Bourdieu s term habitus refers to a system of dispositions which structure social fields. It is argued that habits come close to the concept of habitus in the sense that the latter consists of particular kinds of habits; those that are related to the reproduction of socioeconomic positions. Habits are thus constituents of a general theory of societal reproduction whereas habitus is a systematic combination of socioeconomic habits. The fourth theme relates to issues of social change and development. The capabilities approach has been associated with the name of Amartya Sen, for example, and it underscores problems inhering in economistic ways of evaluating social development. However, Sen s argument has some theoretical problems. For example, his theory cannot adequately confront the problem of relativism. In addition, Sen s discussion lacks also a theory of the role of the public. With the help of arguments derived from pragmatism, one gets an action-based, socially constituted view of freedom in which the role of the public is essential. In general, it is argued that a socially constituted view of agency does not necessarily to lead to pessimistic conclusions about the freedom of action.

Spin-orbital ordering and mesoscopic phase separation in the double perovskite Ca2FeReO6

Neutron powder diffraction measurements on Ca2FeReO6 reveal that this double perovskite orders ferrimagnetically and shows anomalous lattice parameter behavior below T-C=521 K. Below similar to300 K and similar to160 K we observe that the high-T monoclinic crystal structure separates into two and three monoclinic phases, respectively. A magnetic field suppresses the additional phases at low T in favor of the highest-T phase. These manifestations of the orbital degree of freedom of Re 5d electrons indicate that these electrons are strongly correlated and the title compound is a Mott insulator, with competing spin-orbitally ordered states.

Localization induced base isolation in fractionally damped non linear system

In the present article we take up the study of nonlinear localization induced base isolation of a 3 degree of freedom system having cubic nonlinearities under sinusoidal base excitation. The damping forces in the system are described by functions of fractional derivative of the instantaneous displacements, typically linear and quadratic damping are considered here separately. Under the assumption of smallness of certain system parameters and nonlinear terms an approximate estimate of the response at each degree of freedom of the system is obtained by the Method of Multiple Scales approach. We then consider a similar system where the nonlinear terms and certain other parameters are no longer small. Direct numerical simulation is made use of to obtain the amplitude plot in the frequency domain for this case, which helps us to establish the efficacy of this method of base isolation for a broad class of systems. Base isolation obtained this way has no counterpart in the linear theory.

Clusters, asters, and collective oscillations in chemotactic colloids

The creation of synthetic systems that emulate the defining properties of living matter, such as motility, gradient-sensing, signaling, and replication, is a grand challenge of biomimetics. Such imitations of life crucially contain active components that transform chemical energy into directed motion. These artificial realizations of motility point in the direction of a new paradigm in engineering, through the design of emergent behavior by manipulating properties at the scale of the individual components. Catalytic colloidal swimmers are a particularly promising example of such systems. Here we present a comprehensive theoretical description of gradient-sensing of an individual swimmer, leading controllably to chemotactic or anti-chemotactic behavior, and use it to construct a framework for studying their collective behavior. We find that both the positional and the orientational degrees of freedom of the active colloids can exhibit condensation, signaling formation of clusters and asters. The kinetics of catalysis introduces a natural control parameter for the range of the interaction mediated by the diffusing chemical species. For various regimes in parameter space in the long-ranged limit our system displays precise analogs to gravitational collapse, plasma oscillations, and electrostatic screening. We present prescriptions for how to tune the surface properties of the colloids during fabrication to achieve each type of behavior.

A Pd-8 Tetrafacial Molecular Barrel as Carrier for Water Insoluble Fluorophore

A new carbazole-based tetraimidazole ligand 1,3,6,8-tetra(1H-imidazol-1-yl)-9-methyl-9H-carbazole (L) has been synthesized. The unsymmetrical nature of L as well as the rotational freedom of imidazole donor moieties around C-N bond make it a special building unit, which upon treatment with cis-(tmeda)Pd(NO3)(2) produced an unprecedented single linkage-isomeric Pd-8 tetrafacial molecular nanobarrel (PSMBR-1) tmeda N,N,N',N'-tetramethylethane-1,2-diamine]. Unlike closed architectures, open barrel architecture of water-soluble PSMBR-1 makes it an ideal host for some water insoluble polyaromatic hydrocarbons in aqueous medium; one such inclusion complex coroneneCPSMBR-1 was characterized by X-ray diffraction study. Moreover, the potential application of PSMER-1 as carrier in aqueous medium for the transportation of water insoluble fluorophore (perylene) for live cell imaging is explored.

Educación y democracia

Resumen: Actualmente hay cierto consenso en la preferencia de la democracia sobre otros sistemas de gobierno; sin embargo, a la hora de cuestionarnos sobre su fundamento filosófico el consenso es más difícil de lograr. En la democracia se valora la participación activa de los ciudadanos y su derecho a una opinión libre, por lo cual algunos planteos consideran que el sistema democrático es incompatible con la defensa de verdades y valores absolutos. Ejemplo de ello es el planteo de Kelsen, quien sostiene que la democracia solo puede fundamentarse sobre una filosofía relativista. Sin embargo, posiciones como estas tropiezan con dificultades y contradicciones de orden lógico, gnoseológico, metafísico, antropológico, psicológico, ético y social. Acarrean consecuencias negativas también en el ámbito educativo. Para responder a estos planteos proponemos volver sobre algunas enseñanzas de Sócrates y repensar la relación entre democracia y educación, verdad y libertad.

La libertad de expresión en el sistema interamericano de protección de los derechos humanos y su incidencia en el derecho interno de los estados parte

Como dice el título de la presente disertación, abordaré la situación de la libertad de expresión en el sistema interamericano de protección de los derechos humanos y su incidencia en el derecho interno de los Estados parte. Voy a dividir esta presentación en tres partes: 1) Una breve descripción del sistema interamericano dentro del marco del Derecho Internacional de los Derechos Humanos, como núcleo del nuevo paradigma del Estado Constitucional de Derecho; 2) Una descripción de la situación de la libertad de expresión en el mencionado marco; 3) Por último, terminaré con algunas reflexiones personales. Como se puede apreciar, la primera y segunda parte son más descriptivas del cuadro de situación y la última más reflexiva de la misma desde el punto de vista filosófico.

Amartya Sen : la idea de la justicia

Resumen: El artículo analiza la importancia del último libro publicado por Amartya Sen, La idea de la justicia, que representa una síntesis de todo su pensamiento. El autor destaca que la importancia de esta obra radica en su dimensión ética, guiada por la razón, y la compara con la teoría de John Rawls, trazando los paralelos y diferencias que existen entre el pensamiento de ambos intelectuales. Luego, Migliore expone los tres grandes temas abordados por Sen en su teoría: la cuestión de la distribución justa de los r ecursos, la democracia o libertad de participación, y los derechos humanos. Finalmente, a modo de conclusión, sugiere que la obra del economista indio tiene interesantes coincidencias con el pensamiento social cristiano.

Habla ahora o calla (forzosamente) para siempre : las convenciones en contra de toda forma de discriminación e intolerancia y su amenaza a la libertad de expresión en los Estados Americanos

En junio de 2013, la Organización de Estados Americanos (en adelante, la “OEA”) adoptó las Convenciones Interamericanas en Contra del Racismo, la Discriminación Racial y Todas las Formas Relacionadas de Intolerancia (en adelante, “CCDI”). Entre otras cosas, estos nuevos instrumentos –que al tiempo de escribir estas líneas no han sido ratificados por ningún Estado de la región– tendrán el efecto de ampliar enormemente la extensión de las llamadas categorías prohibidas de discriminación más allá de lo que hoy existe en los tratados vigentes que tocan la materia, además de crear un amplio rango de nuevas obligaciones y deberes para los Estados partes en el sentido de promover la igualdad y eliminar la discriminación y la intolerancia. Aún cuando existen múltiples aspectos de esta convención que son susceptibles de ser criticados desde una perspectiva jurídica y de política pública, este ensayo lidia exclusivamente con la cuestión de la novel definición legal de la “intolerancia” como un acto o expresión prohibida, y con los deberes que asumirán los Estados en relación con la misma...
