International Initiatives for Regulating Access to Genetic Resources

In light of the various international instruments and international agencies that are actively engaged in resolving the issue of ABS, the present work tries to find an answer to the larger question how far the above agencies have succeeded in regulating access and make sure of benefit sharing. In this process, the work comprehensively analyses the work of different agencies involved in the process. It tries to find out the major obstacles that stand in the way of fulfilment of the benefit sharing objective and proposes the ways and means to tackle them. The study first traces the legal foundations of the concept of property in GRs and associated TK.For this, it starts with analysis of the nature of property and the questions related to ownership in GRs as contained in the CBD as well as in various State legislations. It further examines the notion of property before and after the enactment of the CBD and establishes that the CBD contains strong private property jurisprudence.Based on the theoretical foundation of private property right,Chapter 3 analyses the benefit sharing mechanism of the CBD, i.e. the Nagoya Protocol. It searches for a theoretical convergence of the notion of property as reflected in the two instruments and successfully establishes the same. It makes an appraisal of the Nagoya regime to find out how far it has gone beyond the CBD in ensuring the task of benefit sharing and the impediments in its way.Realizing that the ITPGRFA forms part of the CBD system, Chapter 4 analyses the benefit sharing structure of ITPGRFA as revealed through its multilateral system. This gives the work the benefit of comparing two different benefit sharing models operating on the same philosophy of property. This chapter tries to find out whether there is conceptual coherence in the notion of property when the benefit sharing model changes. It alsocompares the merits and demerits of both the systems and tries to locate the hurdles in achieving benefit sharing. Aware of the legal impediments caused by IPRs in the process of ABS, Chapter 5 tries to explore the linkages between IPRs and GRs and associated TK and assesses why contract-based CBD system fails before the monopoly rights under TRIPS. Chapter 6 analyses the different solutions suggested by the international community at the TRIPS Council as well as the WIPO (World Intellectual property Organisation) and examines their effectiveness. Chapter 7 concludes that considering the inability of the present IP system to understand the grass root realities of the indigenous communities as well as the varying situations of the country of origin, the best possible way to recognise the CBD goals in the TRIPS could be better achieved through linking the two instruments by means of the triple disclosure requirement in Article 29 as suggested by the Disclosure Group during the TRIPS Council deliberations. It also recommends that considering the nature of property in GR, a new section/chapter in the TRIPS dealing with GRs would be another workable solution.

Pertormer’s Rights in India

The overall focus of the thesis involves the performer's rights in india -A study with special reference to the audiovisual industry.The performer is the disseminator of works of literary, dramatic artistic and musical authorship .The challenge of studying the audiovisual industry is the low level of data documentation and transparency in transactions compounded by the low awareness of legal issues. The first five chapters of the study trace the evolution of performers’ rights with particular impetus on three diverse jurisdictions both at the judicial and statutory levels as well as from the collective bargaining platform.The study also seeks to pin point the major obstacles that the performers have had to encounter in their quest for equal rights under the umbrella of intellectual property the world over.the status of the performer through the international instruments - the Rome convention, the WPPT and the envisaged Protocol to the audiovisual performance.A grant of rights to the performer either under Copyright or labor law need not improve matters for the performer unless the institutional grievance redressal is firmly put in place.There is a need for clearer delineation between the definitions of audio and audiovisual fixations. Under the Indian law the terms representing these have been sound records and cinematographs respectivel.Performer and the Philosophy of Intellectual Propertyeffectively. But this is not to deny the fact that these institutions, organizations and practices could very well rise to the occasion when the rights regime comes into force.

Challenges Faced by Kerala Tourism Industry

Tourism being a smokeless industry is now a multi-billion, multi-sectoral and multi-dimensional activity in the world. Twenty first century tourism has reached up to space when a Russian rocket carried the space vehicle of Dennis Tito, an American businessman and the world’s first space tourist, to the space station. Time is not too far to carry tourists to moon and other planets in specially launched vehicles. Tourism is being considered as an agent of social change bridging gaps among nations, regions and people and helping them to open up. It is a promoter of development-material and spiritual both at macro and micro level. The General Assembly of the United Nations, in designating the year 1967 as ‘International Tourism Year’ recognized the importance of international travel as a means of fostering understanding among people, and giving them a knowledge of the rich heritage of the past civilizations, a better appreciation of the values of different cultures, thus contributing to the strengthening of world peace. It adopted the theme “Tourism-Passport to peace”. Our veteran national leader and the first Prime Minister of India, Jawaharlal Nehru had said” welcome a tourist and send back a friend” which indicates the need for extending friendly hospitality to the in bound tourists. Modern transportation has removed the obstacles of distance enabling people to appreciate each other engage in the exchange of ideas and commerce. Tourism can help overcome real prejudices and foster bonds. Tourism can be a real force of world peace. Considering the vast and varied potential of tourism in the state and its impact on the economic, social and cultural environment of the state, a detailed study is found to be relevant and imperative

Protein-Expressions-Analysen zur Etablierung prädiktiver Biomarker bei der Behandlung fortgeschrittener Tumoren der Mamma und der Prostata

Aktuelle Entwicklungen auf dem Gebiet der zielgerichteten Therapie zur Behandlung maligner Erkrankungen erfordern neuartige Verfahren zur Diagnostik und Selektion geeigneter Patienten. So ist das Ziel der vorliegenden Arbeit die Identifizierung neuer Zielmoleküle, die die Vorhersage eines Therapieerfolges mit targeted drugs ermöglichen. Besondere Aufmerksamkeit gilt dem humanisierten monoklonalen Antikörper Trastuzumab (Herceptin), der zur Therapie Her-2 überexprimierender, metastasierter Mammakarzinome eingesetzt wird. Jüngste Erkenntnisse lassen eine Anwendung dieses Medikamentes in der Behandlung des Hormon-unabhängigen Prostatakarzinoms möglich erscheinen. Therapie-beeinflussende Faktoren werden in der dem Rezeptor nachgeschalteten Signaltransduktion oder Veränderungen des Rezeptors selbst vermutet. Mittels Immunhistochemie wurden die Expressions- und Aktivierungsniveaus verschiedener Proteine der Her-2-assoziierten Signaltransduktion ermittelt; insgesamt wurden 37 molekulare Marker untersucht. In Formalin fixierte und in Paraffin eingebettete korrespondierende Normal- und Tumorgewebe von 118 Mammakarzinom-Patientinnen sowie 78 Patienten mit Prostatakarzinom wurden in TMAs zusammengefasst. Die in Zusammenarbeit mit erfahrenen Pathologen ermittelten Ergebnisse dienten u.a. als Grundlage für zweidimensionales, unsupervised hierarchisches clustering. Ergebnis dieser Analysen war für beide untersuchten Tumorentitäten die Möglichkeit einer Subklassifizierung der untersuchten Populationen nach molekularen Eigenschaften. Hierbei zeigten sich jeweils neue Möglichkeiten zur Anwendung zielgerichteter Therapien, deren Effektivität Inhalt weiterführender Studien sein könnte. Zusätzlich wurden an insgesamt 43 Frischgeweben die möglichen Folgen des sog. shedding untersucht. Western Blot-basierte Untersuchungen zeigten hierbei die Möglichkeit der Selektion von Patienten aufgrund falsch-positiver Befunde in der derzeit als Standard geltenden Diagnostik. Zusätzlich konnte durch Vergleich mit einer Herceptin-sensitiven Zelllinie ein möglicher Zusammenhang eines Therapieerfolges mit dem Phosphorylierungs-/ Aktivierungszustand des Rezeptors ermittelt werden. Fehlende klinische Daten zum Verlauf der Erkrankung und Therapie der untersuchten Patienten lassen keine Aussagen über die tatsächliche Relevanz der ermittelten Befunde zu. Dennoch verdeutlichen die erhaltenen Resultate eindrucksvoll die Komplexität der molekularen Vorgänge, die zu einem Krebsgeschehen führen und damit Auswirkungen auf die Wirksamkeit von targeted drugs haben können. Entwicklungen auf dem Gebiet der zielgerichteten Therapie erfordern Verbesserungen auf dem Gebiet der Diagnostik, die die sichere Selektion geeigneter Patienten erlauben. Die Zukunft der personalisierten, zielgerichteten Behandlung von Tumorerkrankungen wird verstärkt von molekularen Markerprofilen hnlich den hier vorgestellten Daten beeinflusst werden.

Mathematical modelling in mathematics education and instruction

This paper aims at giving a concise survey of the present state-of-the-art of mathematical modelling in mathematics education and instruction. It will consist of four parts. In part 1, some basic concepts relevant to the topic will be clarified and, in particular, mathematical modelling will be defined in a broad, comprehensive sense. Part 2 will review arguments for the inclusion of modelling in mathematics teaching at schools and universities, and identify certain schools of thought within mathematics education. Part 3 will describe the role of modelling in present mathematics curricula and in everyday teaching practice. Some obstacles for mathematical modelling in the classroom will be analysed, as well as the opportunities and risks of computer usage. In part 4, selected materials and resources for teaching mathematical modelling, developed in the last few years in America, Australia and Europe, will be presented. The examples will demonstrate many promising directions of development.

Biological Photonic Crystals: Diatoms

The aim of this work was to produce a variety of fluorescent diatom cell wall material as a basis for spectroscopic investigations of the influence of the photonic structure on the emission of an incorporated laser dye. This goal was achieved by the method of in vivo-fluorochromation, in which the fluorescence dyes are incorporated by the diatom cells during cell wall formation. Several fluorescent dyes (mostly rhodamines) known as strong laser dyes, were tested for a possible application within this method. The results of this work show that half of the tested rhodamines can be applied for an in vivo-fluorochromation of diatom cells. For a successful incorporation into the diatom cell wall, a relatively low toxicity to diatom cells is necessary. Replacement of the carbon acid function at the carboxyphenyl ring of the rhodamine by a methyl or ethylester function showed to convert a rhodamine of relatively low toxicity to a rhodamine leading to severe lethal effects within the cells. In contrast to their carbon acid forms, which posses a net neutral charge of the molecule, rhodamine esters exhibit a net positive charge. The enhanced toxicological effects seem to be due to an increased accumulation of positive charged rhodamines within the mitochondria, an increased hydrophobicity due to the attachment of an alkyl substituent, an increased retention time of the dyes within the mitochondria and a therefore stronger negative effect on the mitochondrial membrane bound energy processes of the diatom cell. Therefore rhodamines with a positive net charge deriving from a methyl or ethylester function at the carboxy phenyl ring instead of a carbon acid substituent showed not to be suitable for long-term investigations/ biomineralization studies of diatoms. Investigations performed on diatom species of different orders showed that rhodamine 19, rhodamine B, and rhodamine 101 can presumably be successfully applied for in vivo-fluorochromation to all diatom species. The results obtained here can help to find further laser dyes for an in vivo-fluorochromation of diatom cells and therefore for the production of fluorescent nanostructural elements for a detailed optical investigation of the diatom cell wall. First optical measurements performed on in vivo-fluorochromated cell walls did not give any hints concerning the photonic structure of the diatom cell. Cell wall parts with different nanostructural elements were investigated and by comparison of the obtained fluorescence emission spectra, no special features that might derive from photonic structural effects could be observed. Results concerning the concentration dependent shifts within the emission spectra, as well as the decrease of fluorescence intensity of the stained cell wall structures with increasing dye concentration, depict that several effects occurring by interaction of the molecules within the cell wall can have an impact on the technical application of fluorescent cell walls. It can be assumed that the investigation of the photonic crystal behaviour and the possibility to achieve laser action within the diatom cell wall can be hampered by molecular interactions. The results give hints to prevent such obstacles. Comparison of the recent findings and state of the art of in vivo-fluorochromation of diatom cell wall material, make clear that the here presented results are of importance and can offer a considerable contribution to the development and establishment of new biosilification markers, for diatoms as well as for other biosilifying organisms.

Biohöfe als Ausgangspunkte informeller Lernprozesse

Die Arbeit befasst sich mit der Frage nach dem Einfluss von Biohöfen auf die Menschen, die in ihrem Umfeld leben. Sie bietet Einblicke in die Zusammenhänge, in denen Nachbarn, Kollegen, Freunde oder Kunden einen Biohof gezielt oder eher zufällig nutzen, um hier informell Erfahrungen zu sammeln, die zu nachhaltigen Lebennstilen und Wirtschaftsweisen beitragen können. Im Rahmen von sechs Fallstudien wurden hierfür ökologisch wirtschaftende Landwirtschaftsbetriebe in Brandenburg im Hinblick auf die informelle Vermittlung von Wissen und Erfahrungen qualitativ untersucht. Mit Hilfe der Grounded Theory wird die Entstehung von informellen Lernprozessen im sozialen Umfeld der Höfe rekonstruiert. Neben dem empirischen Ausgangsmaterial erwiesen sich die handlungstheoretischen Konstrukte Lebenswelt, Habitus, Lebensstil und Lebensführung als hilfreicher Interpretationshintergrund. Mit diesen theoretischen Ansätzen werden die soziokulturellen Einflussfaktoren für Erfahren, Lernen und Vermitteln betont. Informelles Lernen wird so als ein sozial eingebetteter Prozess verstanden. Aus dieser, weniger subjektorientierten Perspektive treten dann Faktoren wie z.B. die Atmosphäre der Beziehung zwischen einer Person und dem Biohof, die sinnliche Wahrnehmung und die Art der Kommunikation in das Blickfeld der Analyse. In der Untersuchung wird eine Vielzahl von Verhaltensänderungen, Denkanstößen und Anregungen benannt, die im Zusammenhang mit den untersuchten Biohöfen geschildert wurden und die im Hinblick auf eine nachhaltige Entwicklung als förderlich eingeschätzt werden. Sie basieren, so der Ansatz der Arbeit, auf informellen Lernprozessen. Das zentrale Ergebnis der Fallanalysen ist eine strukturierte Zusammenstellung der im Untersuchungskontext relevanten Einflussfaktoren für erfolgreiches informelles Lernen. Als wesentliche erscheinen hierbei insbesondere zwei Variablen: zum einen hat sich das „wohlwollende Interesse“ als förderlich für das Zustandekommen und den Verlauf von informellen Lernprozessen herausgestellt. Mit diesem Begriff wird eine Einstellung dem Biohof gegenüber beschrieben, die ein Wohlgesonnensein, das Vertrauen und die Neugierde am Hof beinhaltet. Zum anderen scheint die „Erlebbarkeit“ der Angebote zur Wissensvermittlung für das informelle, habitus- und lebensstilbezogene Lernen bedeutsam zu sein. Ergänzend zu dem auf die lernenden Subjekte gerichteten Fokus wurden in der Forschungsarbeit auch Beweggründe der Betriebsleiter, für die jeweils praktizierte Wissens- und Erfahrungsvermittlung herausgearbeitet. Die Betrachtung wird durch die Zusammenstellung von Schwierigkeiten und Hindernissen abgerundet, die dem informellen Lernen vom Biohof entgegen stehen können. Ausgehend von den fallbezogenen Ergebnissen liefert die Arbeit damit eine Grundlage, um über die Bedeutung von Lernfeldern, die durch Biolandwirte, aber auch andere Akteursgruppen bereit gestellt werden, nachzudenken und um ihre gesellschaftliche Relevanz zu diskutieren.

Learning achievements of farmers during the transition to market-oriented organic agriculture in rural Uganda

Organic agriculture requires farmers with the ability to develop profitable agro-enterprises on their own. By drawing on four years of experiences with the Enabling Rural Innovation approach in Uganda, we outline how smallholder farmers transition to organic agriculture and, at the same time, increase their entrepreneurial skills and competences through learning. In order to document this learning we operationalised the Kirkpatrick learning evaluation model, which subsequently informed the collection of qualitative data in two study sites. Our analysis suggests that the Enabling Rural Innovation approach helps farmers to develop essential capabilities for identifying organic markets and new organic commodities, for testing these organic commodities under varying organic farm management scenarios, and for negotiating contracts with organic traders. We also observed several obstacles that confront farmers’ transition to organic agriculture when using the Enabling Rural Innovation approach. These include the long duration of agronomic experimentation and seed multiplication, expensive organic certification procedures and the absence of adequate mechanism for farmers to access crop finance services. Despite prevailing obstacles we conclude that the Enabling Rural Innovation approach provides a starting point for farmers to develop entrepreneurial competences and profitable agro-enterprises on their own.

The status and barriers to the implementation and continuation of the school gardening projects in Germany, Nigeria and the United States of America

In drawing a conclusion for this study, care must be taken in generalizing findings since the population of students and teachers investigated were limited to certain levels in the different schools and countries. This study recognized some complexity of the factors underlying the status of school gardening instruction and activities in Germany, Nigeria and the U.S. as inadequate time for decision-making in the process of gardening, motivation of teachers and students. This was seen as the major impediments that influenced the status of gardening in the three countries. However, these factors were considered to have affected students’ mode of participation in the school gardening projects. This research finding suggests that the promotion and encouragement of students in gardening activities will promote vegetable production and increasing the numbers of practical farmers. Gardening has the potential to create opportunities for learning in an environment where children are able to experience nature first hand and to use the shared experience for communication (Bowker & Tearle, 2007). Therefore, the need for students to be encouraged to participate in gardening programs as the benefit will not only reduce the rate of obesity currently spreading among youths, but will contribute to the improve knowledge on science subjects. To build a network between community, parents and schools, a parent’s community approach should be used as the curriculum. The community approach will tighten the link between schools; community members, parents, teachers and students. This will help facilitate a better gardening projects implementation. Through a close collaboration, teachers and students will be able to identify issues affecting communities and undertake action learning in collaboration with community organizations to assess community needs and plan the implementation strategies as parents are part of the community. The sense of efficacy is a central factor in motivational and learning processes that govern educational improvement, standard and performance on complex tasks of both teachers and students. Dedication and willingness are the major stimulator and achievement of a project. Through a stimulator and provision of incentives and facilities, schools can achieve the best in project development. Teachers and principals should be aware that students are the lever for achieving the set goals in schools. Failure to understand what students need will result in achieving zero result. Therefore, it is advised that schools focus more on how to lure students to work through proper collaboration with the parents and community members. Principals and teachers should identify areas where students need to be corrected, helping them to correct the problem will enable them be committed in the schools’ programs.

Knowledge Building in Landscape Architecture

The objective of this study was to develop an internet-based seminar framework applicable for landscape architecture education. This process was accompanied by various aims. The basic expectation was to keep the main characteristics of landscape architecture education also in the online format. On top of that, four further objectives were anticipated: (1) training of competences for virtual team work, (2) fostering intercultural competence, (3) creation of equal opportunities for education through internet-based open access and (4) synergy effects and learning processes across institutional boundaries. This work started with the hypothesis that these four expected advantages would compensate for additional organisational efforts caused by the online delivery of the seminars and thus lead to a sustainable integration of this new learning mode into landscape architecture curricula. This rationale was followed by a presentation of four areas of knowledge to which the seminar development was directly related (1) landscape architecture as a subject and its pedagogy, (2) general learning theories, (3) developments in the ICT sector and (4) wider societal driving forces such as global citizenship and the increase of open educational resources. The research design took the shape of a pedagogical action research cycle. This approach was constructive: The author herself is teaching international landscape architecture students so that the model could directly be applied in practice. Seven online seminars were implemented in the period from 2008 to 2013 and this experience represents the core of this study. The seminars were conducted with varying themes while its pedagogy, organisation and the technological tools remained widely identical. The research design is further based on three levels of observation: (1) the seminar design on the basis of theory and methods from the learning sciences, in particular educational constructivism, (2) the seminar evaluation and (3) the evaluation of the seminars’ long term impact. The seminar model itself basically consists of four elements: (1) the taxonomy of learning objectives, (2) ICT tools and their application and pedagogy, (3) process models and (4) the case study framework. The seminar framework was followed by the presentation of the evaluation findings. The major findings of this study can be summed up as follows: Implementing online seminars across educational and national boundaries was possible both in term of organisation and technology. In particular, a high level of cultural diversity among the seminar participants has definitively been achieved. However, there were also obvious obstacles. These were primarily competing study commitments and incompatible schedules among the students attending from different academic programmes, partly even in different time zones. Both factors had negative impact on the individual and working group performances. With respect to the technical framework it can be concluded that the majority of the participants were able to use the tools either directly without any problem or after overcoming some smaller problems. Also the seminar wiki was intensively used for completing the seminar assignments. However, too less truly collaborative text production was observed which could be improved by changing the requirements for the collaborative task. Two different process models have been applied for guiding the collaboration of the small groups and both were in general successful. However, it needs to be said that even if the students were able to follow the collaborative task and to co-construct and compare case studies, most of them were not able to synthesize the knowledge they had compiled. This means that the area of consideration often remained on the level of the case and further reflections, generalisations and critique were largely missing. This shows that the seminar model needs to find better ways for triggering knowledge building and critical reflection. It was also suggested to have a more differentiated group building strategy in future seminars. A comparison of pre- and post seminar concept maps showed that an increase of factual and conceptual knowledge on the individual level was widely recognizable. Also the evaluation of the case studies (the major seminar output) revealed that the students have undergone developments of both the factual and the conceptual knowledge domain. Also their self-assessment with respect to individual learning development showed that the highest consensus was achieved in the field of subject-specific knowledge. The participants were much more doubtful with regard to the progress of generic competences such as analysis, communication and organisation. However, 50% of the participants confirmed that they perceived individual development on all competence areas the survey had asked for. Have the additional four targets been met? Concerning the competences for working in a virtual team it can be concluded that the vast majority was able to use the internet-based tools and to work with them in a target-oriented way. However, there were obvious differences regarding the intensity and activity of participation, both because of external and personal factors. A very positive aspect is the achievement of a high cultural diversity supporting the participants’ intercultural competence. Learning from group members was obviously a success factor for the working groups. Regarding the possibilities for better accessibility of educational opportunities it became clear that a significant number of participants were not able to go abroad during their studies because of financial or personal reasons. They confirmed that the online seminar was to some extent a compensation for not having been abroad for studying. Inter-institutional learning and synergy was achieved in so far that many teachers from different countries contributed with individual lectures. However, those teachers hardly ever followed more than one session. Therefore, the learning effect remained largely within the seminar learning group. Looking back at the research design it can be said that the pedagogical action research cycle was an appropriate and valuable approach allowing for strong interaction between theory and practice. However, some more external evaluation from peers in particular regarding the participants’ products would have been valuable.

Local food security initiatives: systemic limitations in Vancouver, Canada

This paper approaches the topic of urban/community gardening not through the lens of urban theory per se but in light of basic farming realities such as growing season and land availability. Food security comprises availability and affordability. In the context of North American and Western European societies, only food affordability normally merits public discourse. In practice, governments have little or no means to change food affordability, in view of prevailing capitalistic free-market structures. In the current wave of popular exuberance, civic politicians and others have promoted the belief that community gardening could be the pathway to produce affordable food. The formidable obstacles to this pursuit include the availability of (low-cost) land within the highly-densified city limit, insufficient ambient temperature and water supply during the growing season and the contemporary structure of society. Overcoming these fundamental hurdles carries significant negative environmental and economic consequences.

Obstáculos a la protección internacional de refugiados. Estudio de caso : refugiados colombianos en Ecuador (1997-2007)

El presente trabajo de investigación es el resultado de un ejercicio analítico sobre la atención a refugiados colombianos en Ecuador durante 1998 a 2007. A continuación se presenta la información analizada y obtenida por la autora para responder a la siguiente pregunta de investigación: ¿Cuáles son los obstáculos alrededor de la cooperación internacional para la buena atención a los refugiados colombianos en Ecuador? La dificultad para garantizar la protección internacional al refugiado radicaría en las rutas comunes que utiliza con el migrante económico. Sin embargo, esta investigación parte del supuesto de que la débil cooperación intergubernamental (entendida como actos de colaboración entre Estados y/o organismos gubernamentales) colombo ecuatoriana y la descoordinación entre las instituciones ecuatorianas y los organismos internacionales de ayuda humanitaria son los obstáculos para la buena atención a los refugiados colombianos en Ecuador. El trabajo de campo realizado en Ecuador constituye la fuente principal de información y análisis de la investigación, y produce un giro en las conclusiones del documento
