Targeted Public Distribution System in Food Grains:Extent of Utlization by the Tribal Population in Kerala

In India, Food Security meant supply of food grains and the medium was Public Distribution System. Public Distribution System (PDS) is a rationing mechanism that entitles households to specified quantities of selected commodities at subsidized prices. The Objectives of PDS are maintaining Price Stability, rationing during times of scarcity, welfare of the poor, and keeping a check on private trade. Kerala has registered remarkable improvement in poverty reduction in general over the years among all social sections, including scheduled caste and scheduled tribe population. As part of the structural adjustment intended to reduce public expenditure, PDS has been modified as Revamped PDS (RPDS) during 1992 and later on as Targeted PDS (TPDS) in 1997, intended to target households on the basis of income criterion, classifying people as Below Poverty Line (BPL) and Above Poverty Line (APL). TPDS provides 25Kg. of food gra.ins through the Fair Price Shops per month @ Rs.3/- per Kg. of rice/ wheat to the BPL category and @Rs.8.90 and Rs.6.7O for rice and wheat respectively to the APL category of people. Since TPDS is intended to target the poor people, the subsidy spent by the government for the scheme should be beneficial to the poor people and naturally they should utilize the benefits by purchasing the food grains allotted under the scheme. Several studies have shown that there is underutilization of the allotments under TPDS. Therefore, the extent of utilization of TPDS in food grains, how and why remains as a major hurdle, in improving the structure and system of PDS. Livelihood of the tribal population being under threat due to increasing degradation of the resources, the targeting system ought to be effective among the tribal population. Therefore, performance of the TPDS in food grains, in terms of the utilization by the tribal population in Kerala, impact thereof and the factors, if any, affecting proper utilization were considered as the research problem in this study. The study concentrated on the pattern of consumption of food grains by the tribal people, whether their hunger needs are met by distribution of food grains through the TPDS, extent to which TPDS in food grains reduce their share of expenditure on food in the total household expenditure, and the factors affecting the utilization of the TPDS in food grains by the tribal population. Going through the literature, it has been noted that only few studies concentrated on the utilization of TPDS in food grains among the tribal population in Kerala.The Research Design used in this study is descriptive in nature, but exploratory in some aspects. Idukki, Palakkad and Wayanad have more than 60% of the population of the tribals in the state. Within the three districts mentioned above, 14 villages with scheduled tribe concentration were selected for the study. 95 tribal colonies were selected from among the various tribal settlements. Collection of primary data was made from 1231 households with in the above tribal colonies. Analysis of data on the socio-economic factors of the tribal people, pattern of food consumption, extent of reduction in the share of expenditure on food among the household expenditure of the tribal people and the impact of TPDS on the tribal families etc. and testing of hypotheses to find out the relation/association of each of the six variables, using the data on BPL and APL categories of households separately have resulted in findings such as six percent of the tribal families do not have Ration Cards, average per capita consumption of food grains by the tribal people utilizing TPDS meets 62% of their minimum requirement, whereas the per capita consumption of food grains by the tribal people is higher than the national average per capita consumption, 63% deficiency in food grains may be felt by tribal people in general, if TPDS is withdrawn, and the deficit for BPL tribal people may be 82%, TPDS facilitates a reduction of 9.71% in the food expenditure among the total household expenditure of the tribal people in general, share of food to non-food among BPL category of tribals is 55:45 and 40:60 among the APL, Variables, viz. household income, number of members in the family and distance of FPS from tribal settlements etc. have influence on the quantity of rice being purchased by the tribal people from the Fair Price Shops, and there is influence of household income and distance of FPS from tribal settlements on the quantity of rice being purchased by the tribal people from the open market. Rationing with differential pricing on phased allotments, rectification of errors in targeting, anomalies in norms and procedures for classifying tribal people as BPL/APL, exclusive Income Generation for tribal population, paddy cultivation in the landholdings possessed by the tribal people, special drive for allotment of Ration Cards to the tribal people, especially those belonging to the BPL category, Mobile Fair Price Shops in tribal settlements, ensure quality of the food grains distributed through the TPDS, distribution of wheat flour in packed condition instead of wheat through the Fair Price Shops are recommended to address the shortcomings and weaknesses of the TPDS vis-avis the tribal population in Kerala.

Microbial enzyme production utilizing banana wastes

A critical survey of the fruits and vegetable markets of the towns and cities in South India reveals that banana fruit stalk wastes share a dominant proportion among the solid wastes generated. In the light of the review of literature presented in the foregoing section, few reports are available on the utilisation of banana waste for the production of alcoholic beverages, biogas, and single cell protein. However, it is not yet tried for the production of industrial enzymes. Moreover, preliminary fermentation studies conducted under uncontrolled conditions revealed that banana fruit stalk could be aptly utilised as solid substrate? for the industrial production of microbial amylases and cellulases at a cheaper cost. Therefore, it was proposed to conduct a detailed study towards the development of a suitable fermentation process for the production of industrial enzymes using banana fruit stalk wastes, which is rich in carbohydrate, as solid substrate, employing bacteria, under SSF.

Palladium Catalyzed Carbon-Carbon/Carbonheteroatom Bond Formation Reactions Utilizing Pentafulvene Derived Bicyclic Hydrazines

The reactions involving fulvenes and its derivatives have received a great deal of attention over the years in synthetic organic chemistry. Functionalizations of fulvenes provide versatile and powerful approaches to various polycyclic systems and natural products. They serve as versatile intermediates in the construction of various ring systems through inter- as well as intramolecular cycloadditions. Compared to the rich literature on the cycloaddition reactions of pentafulvenes, much less attention has been paid to the synthetic utilization of their cycloadducts. Tactical manipulations on the chosen adduct offer the prospects for designing a variety of useful molecular skeletons. Addition of heterodienophiles to fulvenes offers an efficient strategy towards the synthesis of azabicyclic olefins. However, there have been no serious attempts to study the synthetic utility of these substrates. In this context and with the intention of utilizing pentafulvenes towards synthetically important molecules, author decided to explore the reactivity of pentafulvene derived azabicyclic olefins. Our attention was focused on the synthetic potential associated with the ring opening of fulvene derived bicyclic hydrazines under palladium catalysis. It was envisioned that the desymmetrization of these adducts using various soft nucleophiles will provide a novel access to synthetically and biologically important alkylidene cyclopentenes. The investigations along this line form the focal theme of this thesis entitled “PALLADIUM CATALYZED CARBONCARBON/ CARBON-HETEROATOM BOND FORMATION REACTIONS UTILIZING PENTAFULVENE DERIVED BICYCLIC HYDRAZINES

Design Of Metal Architectures: Synthesis And Study Of Their Photophysical And Biomolecular Recognition Properties

Design and study of molecular receptors capable of mimicking natural processes has found applications in basic research as well as in the development of potentially useful technologies. Of the various receptors reported, the cyclophanes are known to encapsulate guest molecules in their cavity utilizing various non–covalent interactions resulting in significant changes in their optical properties. This unique property of the cyclophanes has been widely exploited for the development of selective and sensitive probes for a variety of guest molecules including complex biomolecules. Further, the incorporation of metal centres into these systems added new possibilities for designing receptors such as the metallocyclophanes and transition metal complexes, which can target a large variety of Lewis basic functional groups that act as selective synthetic receptors. The ligands that form complexes with the metal ions, and are capable of further binding to Lewis-basic substrates through open coordination sites present in various biomolecules are particularly important as biomolecular receptors. In this context, we synthesized a few anthracene and acridine based metal complexes and novel metallocyclophanes and have investigated their photophysical and biomolecular recognition properties.

Efficient Watermarking Schemes for Speaker Verification Guaranteeing Non-repudiation

Presently different audio watermarking methods are available; most of them inclined towards copyright protection and copy protection. This is the key motive for the notion to develop a speaker verification scheme that guar- antees non-repudiation services and the thesis is its outcome. The research presented in this thesis scrutinizes the field of audio water- marking and the outcome is a speaker verification scheme that is proficient in addressing issues allied to non-repudiation to a great extent. This work aimed in developing novel audio watermarking schemes utilizing the fun- damental ideas of Fast-Fourier Transform (FFT) or Fast Walsh-Hadamard Transform (FWHT). The Mel-Frequency Cepstral Coefficients (MFCC) the best parametric representation of the acoustic signals along with few other key acoustic characteristics is employed in crafting of new schemes. The au- dio watermark created is entirely dependent to the acoustic features, hence named as FeatureMark and is crucial in this work. In any watermarking scheme, the quality of the extracted watermark de- pends exclusively on the pre-processing action and in this work framing and windowing techniques are involved. The theme non-repudiation provides immense significance in the audio watermarking schemes proposed in this work. Modification of the signal spectrum is achieved in a variety of ways by selecting appropriate FFT/FWHT coefficients and the watermarking schemes were evaluated for imperceptibility, robustness and capacity char- acteristics. The proposed schemes are unequivocally effective in terms of maintaining the sound quality, retrieving the embedded FeatureMark and in terms of the capacity to hold the mark bits. Robust nature of these marking schemes is achieved with the help of syn- chronization codes such as Barker Code with FFT based FeatureMarking scheme and Walsh Code with FWHT based FeatureMarking scheme. An- other important feature associated with this scheme is the employment of an encryption scheme towards the preparation of its FeatureMark that scrambles the signal features that helps to keep the signal features unreve- laed. A comparative study with the existing watermarking schemes and the ex- periments to evaluate imperceptibility, robustness and capacity tests guar- antee that the proposed schemes can be baselined as efficient audio water- marking schemes. The four new digital audio watermarking algorithms in terms of their performance are remarkable thereby opening more opportu- nities for further research.

Professionalisation of management on German universities: the research liaison officers

Occupations of higher education institutions such as public relations offices, research liaison offices etc. are increasing. A study related to research liaison officers was conducted in Germany to identify activity profiles and qualifications. Results show no standardised education or training, but only learning by doing. From the viewpoint of professionalisation theories a reasonable professionalisation can only be achieved through an organisation of the various occupations in the field of med-level university management as a whole. Proposals for professionalisation were made, such as more systematic education and improved integration into the organisation of HEIs. Staff development is needed as well as more jobs.

Higher Education Governance in Vietnam: University Action, the State and Changing Relationships

Diese Dissertation stellt eine Studie da, welche sich mit den Änderungen in der Governance der Hochschulbildung in Vietnam beschäftigt. Das zentrale Ziel dieser Forschungsarbeit ist die Untersuchung der Herkunft und Änderung in der Beziehung der Mächte zwischen dem vietnamesischen Staat und den Hochschulbildungsinstituten (HI), welche hauptsächlich aus der Interaktion dieser beiden Akteure resultiert. Die Macht dieser beiden Akteure wurde im sozialen Bereich konstruiert und ist hauptsächlich durch ihre Nützlichkeit und Beiträge für die Hochschulbildung bestimmt. Diese Arbeit beschäftigt sich dabei besonders mit dem Aspekt der Lehrqualität. Diese Studie nimmt dabei die Perspektive einer allgemeinen Governance ein, um die Beziehung zwischen Staat und HI zu erforschen. Zudem verwendet sie die „Resource Dependence Theory“ (RDT), um das Verhalten der HI in Bezug auf die sich verändernde Umgebung zu untersuchen, welche durch die Politik und eine abnehmende Finanzierung charakterisiert ist. Durch eine empirische Untersuchung der Regierungspolitik sowie der internen Steuerung und den Praktiken der vier führenden Universitäten kommt die Studie zu dem Schluss, dass unter Berücksichtigung des Drucks der Schaffung von Einkommen die vietnamesischen Universitäten sowohl Strategien als auch Taktiken entwickelt haben, um Ressourcenflüsse und Legitimität zu kontrollieren. Die Entscheidungs- und Zielfindung der Komitees, die aus einer Mehrheit von Akademikern bestehen, sind dabei mächtiger als die der Manager. Daher werden bei initiativen Handlungen der Universitäten größtenteils Akademiker mit einbezogen. Gestützt auf die sich entwickelnden Muster der Ressourcenbeiträge von Akademikern und Studierenden für die Hochschulbildung prognostiziert die Studie eine aufstrebende Governance Konfiguration, bei der die Dimensionen der akademischen Selbstverwaltung und des Wettbewerbsmarktes stärker werden und die Regulation des Staates rational zunimmt. Das derzeitige institutionelle Design und administrative System des Landes, die spezifische Gewichtung und die Koordinationsmechanismen, auch als sogenanntes effektives Aufsichtssystem zwischen den drei Schlüsselakteuren - der Staat, die HI/Akademiker und die Studierenden – bezeichnet, brauchen eine lange Zeit zur Detektion und Etablierung. In der aktuellen Phase der Suche nach einem solchen System sollte die Regierung Management-Tools stärken, wie zum Beispiel die Akkreditierung, belohnende und marktbasierte Instrumente und das Treffen informations-basierter Entscheidungen. Darüber hinaus ist es notwendig die Transparenz der Politik zu erhöhen und mehr Informationen offenzulegen.

Research and teaching: a holy or an unholy alliance?

Much of the self-image of the Western university hangs on the idea that research and teaching are intimately connected. The central axiom here is that research and teaching are mutually supportive of each other. An institution lacking such a set of relationships between research and teaching falls short of what it means to be a university. This set of beliefs raises certain questions: Is it the case that the presence of such a mutually supportive set of relationships between research and teaching is a necessary condition of the fulfilment of the idea of the university? (A conceptual question). And is it true that, in practice today, such a mutually supportive set of relationships between research and teaching characterises universities? (An empirical question). In my talk, I want to explore these matters in a critical vein. I shall suggest that: a) In practice today, such a mutually supportive set of relationships between research and teaching is in jeopardy. Far from supporting each other, very often research and teaching contend against each other. Research and teaching are becoming two separate ideologies, with their own interest structures. b) Historically, the supposed tight link between research and teaching is both of recent origin and far from universally achieved in universities. Institutional separateness between research and teaching is and has been evident, both across institutions and even across departments in the same institution. c) Conceptually, research and teaching are different activities: each is complex and neither is reducible to the other. In theory, therefore, research and teaching may be said to constitute a holy alliance but in practice, we see more of an unholy alliance. If, then, in an ideal world, a positive relationship between research and teaching is still a worthwhile goal, how might it be construed and worked for? Seeing research and teaching as two discrete and unified sets of activity is now inadequate. Much better is a construal of research and teaching as themselves complexes, as intermingling pools of activity helping to form the liquid university that is emerging today. On this view, research and teaching are fluid spaces, ever on the move, taking up new shapes, and themselves dividing and reforming, as the university reworks its own destiny in modern society. On such a perspective, working out a productive relationship between research and teaching is a complex project. This is an alliance that is neither holy nor unholy. It is an uneasy alliance, with temporary accommodations and continuous new possibilities

Análisis de una iniciativa estudiantil de investigación surgida en Criptogamia, una asignatura optativa de segundo ciclo de Biología = Analysis of a students’ research initiative originating in Cryptogamy, an elective course in the last two years of the Biology degree

Presentamos una experiencia exitosa de aprendizaje que partió de Criptogamia (asignatura optativa de segundo ciclo de Biología), que dio lugar a un proyecto de investigación gestionado por los propios alumnos. La iniciativa se consolidó estableciendo una Asociación de Estudiantes centrada en investigación y divulgación. En poco tiempo, los participantes han presentado comunicaciones científicas, y organizado actividades dirigidas a diversos públicos, dentro y fuera de la comunidad universitaria. Actualmente se plantea una colaboración multidisciplinar con otros organismos de investigación y la extensión de su ámbito de estudio. Abordamos su incidencia en el aprendizaje en varios aspectos: científico (técnicas específicas, rigor, búsqueda de información e interpretación de resultados), comunicativo (estructuración y presentación de la información obtenida, para diversos públicos), y organizativo, incluyendo el trabajo en equipo. Aunque de carácter espontáneo, esta experiencia muestra rasgos evaluables en cuanto a sus posibilidades para otras asignaturas. Analizamos las características y planteamiento de esta optativa, el perfil de sus alumnos, y el contexto universitario que la acoge. Detectamos como factores principales los aspectos participativos de la asignatura, la cohesión del grupo, el carácter voluntario de la implicación, los beneficios percibidos por los estudiantes, y la disponibilidad de recursos humanos (supervisión) y materiales (equipamiento y subvenciones)

What is Abstinence? Definitions and Examples of Abstinence, to Prevent the Sexual Transmission of the HIV Virus, According to Spanish University Students

Research carried out in several Anglo-Saxon countries shows that many undergraduates identify oral sex and anal sex as examples of abstinent behaviour, while many others consider kissing and masturbation as examples of having sex. The objective of this research was to investigate whether a sample of Spanish students gave similar replies. Seven hundred and fifty undergraduates (92% aged under 26, 67.6% women) produced examples or definitions of the term ‘abstinence’. Spanish students made similar errors to those observed in the Anglo-Saxon samples, in that behaviours that were abstinent from a preventive point of view (masturbating and sex without penetration) were not considered as such, while a number of students reported oral sex as abstinent behaviour. The results suggest that the information on risky and preventive sexual behaviour should cease to use ambiguous or euphemistic expressions and use vocabulary that is clear and comprehensible to everyone

W3233 -- Networks and Complexity in Social Systems (Collective Dynamics Group ISERP -- Columbia University) Course Syllabus

The Networks and Complexity in Social Systems course commences with an overview of the nascent field of complex networks, dividing it into three related but distinct strands: Statistical description of large scale networks, viewed as static objects; the dynamic evolution of networks, where now the structure of the network is understood in terms of a growth process; and dynamical processes that take place on fixed networks; that is, "networked dynamical systems". (A fourth area of potential research ties all the previous three strands together under the rubric of co-evolution of networks and dynamics, but very little research has been done in this vein and so it is omitted.) The remainder of the course treats each of the three strands in greater detail, introducing technical knowledge as required, summarizing the research papers that have introduced the principal ideas, and pointing out directions for future development. With regard to networked dynamical systems, the course treats in detail the more specific topic of information propagation in networks, in part because this topic is of great relevance to social science, and in part because it has received the most attention in the literature to date.
