Rapid urbanization and agricultural intensification are currently impacting the soils of many tropical countries. Bangalore is a growing megacity experiencing both issues and their derived ecological and socio-economic effects. This paper seeks to understand how the socio-economic effects of urbanization are affecting soil organic carbon (SOC) in Bangalore’s rural–urban interface. We first compiled information on how management practices affect SOC dynamics and specifically evaluated the effects of fertilization practices on SOC levels in major cropping systems. We then used interview data from farmers’ households across an urbanity gradient in Bangalore to test the association between urbanization as well as related socio-economic drivers and farming practices. We found that fertilization increases SOC concentrations, especially when mineral fertilizer is combined with additional farmyard manure. Single mineral fertilizer and a combination of mineral fertilizer and farmyard manure are commonly applied in Bangalore. Conservation practices, such as reduced tillage and mulching, are applied by 48% and 16% of households, respectively. Farm and household characteristics, including market integration, are the most important determinants of management decisions that affect SOC. Our study shows that improving farm and household conditions and opportunities, independently of the degree of urbanity, is necessary for implementing agricultural practices that can benefit SOC in Bangalore.

Bangalore was built by Magadi Kempegowda at 1537. Bangalore ruled by various kingdom in 1758- Hyder Ali, in 1799- British overthrew Tippu sultan, in 1881- Mysore wodeyar, After the independence, Bangalore was designed as the capital of Mysore state in 1956, Bangalore Metropolitan Region comprises Bangalore urban district, Bangalore rural district & Ramanagara district. The Bangalore Metropolitan Region lies towards the south-east in the south Indian state of Karnataka. The Bangalore Metropolitan Region situated between 12◦ 14’ 16” to 13◦ 30’ 26” north latitude & 77◦ 2’ 51” to 77◦ 57’ 45” east longitude.

To reach set goals first literature collected from various works and to prepare maps for topography of Bangalore metropolitan region remote sensing data and GIS techniques are used. Bangalore is fast growing metropolitan city hence to know and mapping of the topography is required. Keywords: Topography; Lithology; soil; remote sensing

Abstract Bengaluru/Bangalore, the capital city of the Indian state of Karnataka, has played a vital role in the advancement of communication and technology across the globe. Following the progressivist logic of neoliberal urbanism, the city evolved from the quiet, placid ‘Pensioners’ Paradise’ into the bustling ‘Silicon Valley of India’ at an accelerated pace. Bangalore’s sudden growth into a global cyberpolis has motivated its recent entry into the realm of crime fiction in English. The current paper draws on this connection and proposes to offer a spatial critique of the crime novels in Anita Nair’s Inspector Gowda series, Cut like Wound (2012) and Chain of Custody (2016), set in Bangalore. To map the transitions in the spatial structures and social relations of this rapidly changing city, it uses interdisciplinary approaches of geocriticism and the postmodern social theories of space. Also, by analysing the representations of residential segregation in Nair’s novels, the paper intends to foreground how social inequalities, gentrification, and ghettoization have contributed to the raging scenario of crime and violence in Bangalore.

The linear trends in the monthly, seasonal and annual mean maximum temperature, minimum temperature, average temperature, diurnal range of temperature, rainfall, relative humidities at 0830 & 1730 hr IST of Bangalore city and airport have been analysed based on the data for the period from 1960-95. The variation in surface wind over Bangalore during above period has also been studied to find out impact of urbanisation on weather parameters. It is found that Bangalore city is becoming warmer in terms of mean maximum & mean minimum temperatures. Rate of increase is significantly higher over Bangalore city (central observatory) than that over airport during winter months. Similarly the rising trend of average temperature of Bangalore city is higher than of Bangalore airport during October to April being significantly so during winter season. Also the diurnal range of temperature of Bangalore is becoming larger in winter months with the rising trend being higher over Bangalore city than over airport. Even though rainfall does not show any significant trend, the rising trend during monsoon & falling trend during post monsoon season over Bangalore city are higher than that of Bangalore airport. Also though both Bangalore city & airport show maximum rising trend in mean relative humidity at 0830 hr IST during winter, the rate of rise is less over Bangalore city. Similarly though the relative humidity at 1730 hr IST shows decreasing trend during all the seasons, the rate of decrease is less over Bangalore city for all seasons except post monsoon season. The mean maximum, minimum and average temperatures and relative humidities show cyclic variation of their monthly trend coefficients during the year.

From 'Pensioners Paradise' or 'Garden City' to 'Silicon Valley' or 'Garbage City', the city of Bangalore has come a long way. One of the interesting aspects of life in Bangalore is 'public life' and the use of public space. However the quality of public spaces in Bangalore has deteriorated over the years due to several reasons. Rapid development, increase in traffic, encroachment into public spaces and lack of management of public spaces have all contributed to this. The CBD (Central Business District) area, especially M.G. Road has evolved as the de-facto centre of Bangalore. Hence a space that used to cater to a city of 2 million in 1980 has to now cater to a city of 5 million. This has led to congestion on M.G. Road, especially along the sidewalk, where people jostle each other to get to their destinations and one can no longer take a leisure stroll or promenade in comfort. Although the sidewalk has been historically an important public space, it is now slowly being reduced to the function of circulation. The increase in population has also altered the demands on public spaces in Bangalore. The cosmopolitan image that Bangalore has acquired has resulted in the creation of many eclectic spaces such as pubs, open-air cafés, and food courts. The common man is being left out of this semi-public realm because of affordability, causing a social rift. Also with pressure increasing on the streets it is becoming difficult to cater to these needs in an appropriate manner. The public realm is slowly diminishing and the semi-private realm is filling the void. This calls for a re-evaluation of the role of a street and how it is functioning in Bangalore and exploration of new spatial types of public spaces, which can be introduced in the public realm. Public spaces should reconcile these differences rather than aggravate them. With pressure on land due to increasing population and density a contest for space is inevitable. What is important is to reconcile these differences and evolve a strategy through which public space can be returned to the people irrespective or religion, caste, creed, class or political alignment for the common good without compromising on aesthetics. At the same time the poor and deprived need to feel a sense of belonging and ownership in the city. Public space is one of the few mediums for such expressions and hence the duty of the city to provide it. Also the absence of iconic public spaces as landmarks has resulted in Bangalore remaining an imageless city, a former middle-class city with no apparent vernacular. Today Bangalore has no real city centre to represent its image and cater to its citizens. The elements of a city centre already exist as observed by Rao & Tewari; it is a matter of giving it structure and a sense of place. Bangalore today confronts several problems with respect to its public spaces ' lack of an imageable city centre; contest for urban and public space based on class and caste; privatisation / corporatisation of public space. To curtail violent and disruptive demonstration of ideas and aspirations by various interest groups especially those of the suppressed, the city needs a democratic, civic space in the perceived/evolving heart of the city ' M.G. Road. Such a space would attempt to bridge the zoning of Bangalore and the lack of imageability of the city; providing its citizens a space to speak their minds, to protest, to celebrate, to mourn, to recreate and most importantly to unite. The thesis document comprises three sections. The first section deals with theory pertaining to the design of public spaces that provides a basis to evaluate public spaces in Bangalore, and draw conclusions, which can be applied in the design project. It draws from public space theory pertaining to the issues identified earlier. The second section provides a brief history of urbanisation of Bangalore. It describes the use of public space from colonial times to the present and draws conclusions for future development of public spaces in Bangalore. The last section applies and tests the conclusions arrived at in the previous two chapters through a design project for a site on Mahatma Gandhi Road. The design process and final product comprises the third section.

Le tryptique ville - mondialisation - migration est mis en perspective dans la thèse à partir d'un poste d'observation situé au Sud : la ville de Bangalore, la cinquième ville de l'Inde par la population, largement présentée comme la « Silicon Valley indienne ». L'objet d'analyse est le phénomène de migration de retour de migrants indiens très qualifiés, salariés du secteur des hautes et des nouvelles technologies, revenant majoritairement des Etats-Unis à Bangalore. La recherche articule géographie des migrations et géographie urbaine dans une démarche compréhensive qui permet d'appréhender les pratiques de l'espace et les significations qui leur sont attachées, ainsi que les échelles collective et individuelle du fait migratoire. Elle interroge ainsi une notion et une catégorie importantes de la géographie des migrations : la migration de retour et les migrants très qualifiés. La thèse montre que le retour s'insère dans les évolutions de la dynamique technopolitaine qui caractérise Bangalore. Elle souligne la pertinence de la notion de migration de retour comme catégorie analytique du projet migratoire des acteurs, comme processus et comme moment de trajectoires migratoires de plus en plus transnationales. Par ailleurs le rôle joué par les migrants dans la fabrique métropolitaine et technopolitaine est mis en évidence par l'étude de leurs pratiques résidentielles, en particulier pour le développement d'un urbanisme d'enclave. Cultivant l'entre-deux, les migrants de retour renforcent le rôle de Bangalore en tant que pôle du champ migratoire indien
The articulation between globalization, migration and urbanization is addressed from a vantage point located in a developing country : the city of Bangalore, fifth city by population of India, which is known also as the ''Silicon Valley of India''. The selected way to assess it has been to focus on the reverse migration flow of high-skilled Indian migrants, coming back from the USA mainly, specifically to Bangalore. This research stands at the intersection of migration studies and urban studies. It proposes a comprehensive approach in order to comprehend the spatial practices as well as their meanings, at both the individual scale and the collective scale. It addresses two important notions in migration studies : return migration and high(ly) skilled migration. This reverse brain drain contributes to the technopolitan dynamic which a salient feature of Bangalore. This study reinforces the relevance of the concept of return migration by analyzing the return migration as a project, as an open-ended-process and a stage in the realm of increasingly transnational life patterns. The thesis addresses also the way these ''returnees'' reinsert themselves in the urban fabric, contributing to some typical trends of the metropolis and technopolis-in-the making such as the development of enclave urbanism, by studying their residential practices. The ''returnees'' remain in an in-between situation that strengthhen Bangalore as a pole in the migration field of Indians

Indien är ett land som växer ekonomiskt samtidigt som problem med hur avfall ska tas omhand fortfarande är i utvecklingsfasen. Studiens fokus ligger på hur avfallshanteringen sköts i staden Bangalore. Utifrån ett svenskt perspektiv på avfallshantering med insamling och behandling har Bangalore undersökts och brister lokaliserats. Förbättringsförslag presenteras utifrån de brister som framkommit och ett fokus har lagts på om svenska avfallslösningar skulle kunna implementeras i Bangalore. Svensk avfallshantering utgör en bra grund för ett funktionellt avfallshanteringssystem och har därför använts som referens vid jämförelser och förbättringsförslag. I Sverige används källsortering vid sortering av avfall för att få en högre grad av återvinningsbarhet. De behandlingssteg som finns ger energi på olika sätt och ytterst lite avfall läggs på deponier. Ett ständigt arbete utförs utifrån avfallstrappans steg. I Bangalore är situationen omvänd och det avfall som lyckas samlas in hamnar till största delen på deponier eller inofficiella dumpningsplatser runt om i staden. I Sverige sköts avfallshanteringen av den formella sektorn medan den i Bangalore till stor del utförs av en informell sektor där privata personer samlar in skräp. En litteraturstudie har gett insikt i vilka problem utvecklingsländer kan ha gällande avfallshantering och även vilka faktorer som spelar in vid verkställandet av ett fungerande system. I projektet gjordes en observationsstudie på plats i Bangalore under två veckors tid. Utifrån observationsstudien kunde mycket av tidigare information kring hur avfallshanteringen går till granskas mer kritiskt och ett mer verklighetstroget resultat framföras. Det saknas ett fungerande system som är heltäckande för hela Bangalore, vilket gör att mycket avfall hamnar direkt på gator eller på övergivna tomter. Detta i sin tur ger upphov till dålig lukt för invånarna och en ohygienisk miljö. De insamlingssystem som finns att tillgå för allmänheten var i övergripande fall otillräckliga. Tre olika faktorer identifierades som hindrar att avfallshanteringen ska kunna fungera. Dessa var politik, den formella och informella sektorn, samt insamlingssystem av avfall. Ett stort hinder inom Bangalore är det bristande politiska intresset att få till en fungerande avfallshantering. Inga stora aktioner eller krafttag tas mot de växande mängder avfall som produceras. Inte heller sker en bra integration mellan de formella avfallsinsamlarna som utgörs av avfallstransporter och avfallsinsamlare versusinofficiella avfallsinsamlare. Då Bangalore saknar ett formellt insamlingssystem ges inte rätta förutsättningar för befolkningen att kunna gå någonstans med sitt avfall. Detta leder till en ökad okunskap om hur avfall bör sorteras för att kunna behandlas på ett lämpligt sätt där föredragsvis energi kan utvinnas. Ett tydligare insamlingssystem behövs om Bangalore ska kunna nå en hållbar utveckling och bromsa de eskalerande miljöproblem som de ställs inför. Någon form av behandling av avfall krävs för att minska mängden avfall som hamnar direkt på deponering. Genom att minska trycket på deponierna finns en potential för att få en hållbar stad.
India is a country that is growing economically while the problems with the waste andit´s treatment are still in the development phase. The study focuses on how the waste ishandled in the city of Bangalore. From a Swedish point of view the waste collection andtreatment have been investigated Bangalore and shortcomings identified. Suggestionsfor improvements are presented from the lack of the waste management and the focushas been on how Swedish solutions could be implemented in Bangalore. In Sweden the sorting of waste at a household level is managed from different fractionsin containers and therefore the waste has a higher degree of recyclability. Theprocessing steps that are providing energy are sufficient leading to very little wastebeing added to landfills. A constant work is done based on the waste hierarchy. InBangalore, the situation is the reverse and the waste collected mostly ends up inlandfills or unofficial dumping sites around the city. In Sweden, waste is handled by theformal sector, while Bangalore is largely dependent on an informal sector whereindividuals collect waste. A literature study has provided insight into the difficulties developing countries mayhave to face regarding waste management and the factors that come into play in theexecution of a functioning system. Within the project, an observational study was madein Bangalore for two weeks. Based on the observational study a lot of previousinformation on how waste is handled could be examined more critically and morerealistic conclusions drawn. The lack of a functioning system for waste collectionthroughout Bangalore results in a lot of waste ending up directly on the streets or onabandoned plots. This in turn gives rise to odors for residents and an unhygienicenvironment. The collection available to the public was in most cases insufficient. Three factors were identified that prevent the waste management from functioning.These were politics, the formal and informal sector, as well as the practical collectionof waste. A major obstacle in Bangalore is the lack of political interest of functioningwaste management. No major action is taken against the growing amounts of wasteproduced. A good integration between the formal waste collectors consisting of thetransport of waste and waste collectors versus informal waste collectors is missing.Bangalore also lacks formal collection systems and the people are not given the rightconditions to be able to go anywhere to get rid of their waste. This leads to increasedignorance about how waste should be sorted for processing appropriately and whereenergy can be recovered. A clearer collection is needed if Bangalore is to achieve sustainable development and tocurb the escalating environmental problems they face. Some form of waste treatment isneeded to reduce the pressure on the city landfill. By doing this there is a change for thecity to be sustainable and green.

The Kabir Project (K.P.) was born in Bangalore, India, in 2002, after the Gujarat pogrom, which occurred in the same year. In the context of increasing divisions in Indian society, defined by religion, social class, caste and gender, this research explores how this initiative, through live concerts and documentary films, spreads the folk music traditions of the 15th century mystic poet Kabir along with his messages of unity and understanding between confronted identity groups. This study presents the context of violence between Muslims and Hindus since the Indian Partition and the reasons for gendered violence in the conflict. It focuses also on the connections between globalization and minorities’ prosecution in liberal democracies; on the colonial roots and socioeconomic reasons which led to the Gujarat massacre in 2002; and the social role of the mystic as bridging cultural and religious differences. Through two complementary methods: in-depth interviews to audiences and organizers at the K. P. festivals in Bangalore and survey questionnaires distributed to the Kabir Festival Mumbai audiences, this study tries to answer the following questions: What is the potential for social change of the K. P. in the world-views of today's Indian citizens? Are the messages presented by films and folk music capable of generating positive attitudes towards dialogue between confronted identity categories? In which ways?The research reveals the success of the K. P. to challenge audiences’ minds through communication for development events, whose objectives are reached by spreading Kabir values through artistic forms, and by creating shared spaces between confronted identity sections. Festivals in rural areas help to diminish the distance between those antagonized communities. In addition, urban festivals also generate positive attitudes in elites towards dialogue and coexistence, since that is the social profile of the audience.

Advocacy of inclusive education is a key part of the United Nations’ broader effort to encourage countries across the world to commit to the provision of 'education for all'. This United Nations educational policy is directed towards promoting social justice and equality and erasing the invisible and tangible barriers that segregate the marginalized sections of society from quality education. The Government of India has endorsed this broad objective and recognized the urgent need to provide equal opportunities to all learners. This commitment becomes complicated when considered within a political and social context that has simultaneously endorsed the significance of education for social development while limiting access to education for various groups, including students with disabilities. In this complex situation teachers’ attitudes towards the implementation of the inclusive education have a major impact upon how students with disabilities actually experience education. Yet relatively little is known about Indian teachers’ attitudes to inclusive education principles and practices and/or how they believe they are able to take up the United Nations’ and the government of India’s apparent commitment to meeting the needs of students with disabilities. In response to this gap in literature and policy, the aim of this mixed method study was to investigate pre-service teachers’ and in-service teachers’ attitudes towards the implementation of inclusive education in the city of Bangalore within Karnataka State, India. The project involved the use of a 30 items questionnaire followed by semi-structured interviews with participants from several groups: pre-service teachers with a special education focus; pre-service, generalist teachers; in-service teachers working in general education settings; and in-service teachers working in special education. This data set was analysed by drawing upon the Theory of Planned Behavior advocated by Ajzen (1991). This analysis highlighted teachers’ beliefs and how these shape their attitudes towards, and actions regarding, inclusive education.

Collapse phenomenon is exhibited by two types of residual soils. The first category of collapsing residual soils is believed to be transported soils that have undergone post-depositional pedogenesis. The second category of collapsing residual soils is highly weathered and leached soils formed by in-situ weathering of parent rock. Residual red soils occur in Bangalore District of Karnataka State. Physical and chemical weathering of the gneissic parent rock formed the residual soils of Bangalore District. The red soils of Bangalore District are generally moderate to very highly porous (porosity range 35-50%). These soils are also unsaturated owing to presence of alternate wet and dry seasons and low ground water table. Moderately to highly porous, unsaturated red soils occur in Pernambuco State of Brazil. These residual soils formed by weathering of gneissic rock significantly collapse on wetting under external pressures. Kaolinite is predominant clay mineral in the red soils of Bangalore and Pernambuco Districts. Similarities exist in the mode of soil formation, clay mineralogy, porosity and degree of saturation (Sr) values of the red soils from Pernambuco State, Brazil, and Bangalore District. Given the collapsible nature of red soils from Pernambuco State, Brazil, the red soils from Bangalore District also deserve to be examined for their potential to collapse in the compacted and undisturbed conditions. The roles of initial dry density, compaction water content, clay content and flooding pressure (the external stress at which a laboratory specimen is inundated is termed as flooding pressure in this thesis) in determining the collapse behaviour of compacted soils are well recognized. However, the influences of above parameters on the collapse behaviour of compacted red soil specimens from Bangalore District are lacking. Such studies are essential as they help to identify the critical compaction parameters (dry density and water content), soil composition, and applied stress level that needs to be controlled by the fill designer in order to minimize wetting-induced collapse. The importance of matric suction in the collapse behaviour of unsaturated soils is well recognized. Yet, the influence of matric suction in the collapse behaviour of compacted soils has only been indirectly examined by varying the compaction water content/degree of saturation of the soil specimens. The climate of Bangalore District is characterized by alternate wet and dry seasons which affects the soil microstructure and the matric suction. Both these parameters have a significant influence on collapse behaviour of unsaturated soils. Cyclic wetting and drying is expected to have a significant bearing on the collapse behaviour of residual soils and is therefore examined. The red soil deposits of Bangalore District are important from foundation engineering view point as they are subjected to structural loading. Owing to the presence of alternate wet and dry seasons and low ground water table, red soil deposits of Bangalore District are more often than not unsaturated. These foundation soils would however be susceptible to increase in moisture content from causes such as infiltration of rainwater, leakage of pipes or watering of lawns and plants. Given the porous and unsaturated nature of undisturbed red soils from Bangalore district, their collapsible nature deserves to be examined for reliable estimation of foundation settlements. To achieve the above objectives, experiments are performed that study: 1.The influence of variations in compaction dry density, initial water content and matric suction, clay content and flooding pressure on the collapse behaviour of a representative red soil sample from Bangalore District. 2.The influence of repeated wetting and drying on the collapse behaviour of compacted red soil specimens. 3.The collapsible nature of undisturbed red soil samples from different locations in Bangalore District. The organization of this thesis is as follows: After the first introductory chapter, a detailed review of literature highlighting the need to study the collapse behaviour of unsaturated red soils of Bangalore District, Karnataka in the compacted and undisturbed states comprises Chapter 2. Chapter 3 presents a detailed experimental programme of the study. Details of representative and undisturbed red soil samples from Bangalore District, Karnataka State, India were used in the study are provided. Determination of collapse potential of compacted and undisturbed soil specimens using conventional oedometer is discussed. Determination of matric suction of compacted and undisturbed specimens by ASTM Filter paper method and pore size distributions by mercury intrusion porosimetry is detailed. Methods to perform cyclic wetting and drying of compacted red soil specimens in modified oedometer assemblies is detailed. These experiments are performed to examine the influence of cyclic wetting and drying on the collapse behaviour of compacted red soil specimens. Chapter 4 examines the collapse behaviour of a compacted red soil from Bangalore District. The influence of variations in compaction dry density, initial water content and matric suction, flooding pressure and clay content on the collapse behaviour of the representative red soil from Bangalore District are examined. Besides measuring the initial matric suction of the compacted red soil specimens, mercury intrusion porosimetry was performed on selected compacted red soil specimens. Experimental results showed that compacted red soils from Bangalore District exhibited tendency to swell and collapse at the experimental range of densities and water contents. Red soil specimens compacted to relative compactions > 90 % at water contents below OMC swelled at flooding pressures lower than 200 kPa. Red soil specimens compacted to relative compactions < 90 % at water contents below OMC significantly collapsed at flooding pressures larger than 200 kPa. Hence maintenance of the design water content during construction of compacted red soil fills is essential to minimize wetting induced volume changes. Experiments showed that the relative abundance of coarse pores (60 to 6 μm, pore radius) were mainly affected on increasing the relative compaction of the specimens from 84 % (dry density = 1.49 Mg/m3) to 100 % (dry density = 1.77 Mg/m3). The relative abundance of the coarse and fine (0.01 to 0.002 μm) pores were both affected on increasing the compaction water content from 10.6 to 26.4 %. These variations in pore size distributions provided better insight into the variations of collapse potential with variations in compaction parameters. ASTM filter paper method showed that for the selected compaction conditions the initial matric suction of the compacted red soil specimens varied between 60 and 10,000 kPa. Further, variations in degree of saturation at a constant relative compaction or variations in relative compaction at a constant degree of soil saturation notably affected the matric suction of the compacted soil specimens. It was also inferred that a clay soil with a higher liquid limit is characterized by a higher matric suction at a given water content. Variations in clay content affected the collapse potentials of soil specimens compacted to dry densities of 1.49 and 1.66 Mg/m3. These specimens exhibited maximum collapse at about 26 % clay content. It is suggested that greater destabilization of inter-particle contacts caused by loss of matric suction on flooding was primarily responsible for the soil specimen containing the critical clay content of 26 % to exhibit maximum collapse potential. Increase in initial dry density, initial water content, clay content of the soil specimen and flooding pressure increased the time-duration of collapse of the compacted soil specimens. The time-duration of collapse was observed to range between 3 and 100 minutes for the tested specimens. Chapter 5 examines the influence of alternate wetting and drying on the collapse behaviour of compacted red soil specimens of Bangalore District. The compacted specimens were subjected to alternate wetting and drying cycles at surcharge pressures of 6.25 and 50 kPa in modified oedometer assemblies. Studies were also performed to examine whether the initial placement conditions have any bearing on the collapse behaviour of red soil specimens subjected to four cycles of wetting and drying. Mercury intrusion porosimetry was performed on a few desiccated red soil specimens. Experimental results showed that cyclic wetting and drying caused the desiccated specimens to exhibit similar or lower swell and collapse potentials than the compacted specimens. Such a behaviour resulted despite the desiccated specimens (specimens subjected to four cycles of wetting and drying are termed as desiccated specimens) possessing similar void ratios but much lower water contents than the compacted specimens. The restraining influence of the desiccation bonds and alteration of soil structure is considered responsible for the reduced swell and collapse tendencies of the desiccated specimens. The desiccation bonds imparted higher apparent preconsolidation pressures to the desiccated specimens. The initial compaction conditions also have a strong bearing on the collapse potentials of the desiccated specimens. Compacted red soil specimens subjected to cyclic wetting and drying under a higher surcharge pressure of 50 kPa exhibited larger swell potentials and lower collapse potentials than specimens desiccated at 6.25 kPa. Besides their lower void ratios, the presence of stronger desiccation bonds also contributed to their lower collapse potentials. The presence of stronger desiccation bonds in specimens desiccated under higher surcharge pressure was indicated by their higher apparent preconsolidation pressures. Chapter 6 examines the collapse behaviour of undisturbed red soil specimens from three locations in Bangalore District at a range of flooding pressures. Studies on the variations in initial water content and effect of remoulding on the collapse behaviour of the undisturbed specimens is supplemented by measuring the initial matric suction and performing mercury intrusion porosimetry experiments. Experimental results showed that based on their collapse potential at 200 kPa, the undisturbed red soils of Bangalore District classified as troublesome to moderately troublesome foundation soils. The bonded structure of the undisturbed red soil specimens imparted them higher apparent preconsolidation pressures and lower swell/collapse potentials than their remoulded counterparts. Variations in in-situ dry density, degree of saturation and relative distribution of pore sizes affected the matric suction and collapse potentials of the undisturbed specimens Chapter 7 summarizes the conclusions of this thesis.

It was also inferred that a clay soil with a higher liquid limit is characterized by a higher matric suction at a given water content. Variations in clay content affected the collapse potentials of soil specimens compacted to dry densities of 1.49 and 1.66 Mg/m3. These specimens exhibited maximum collapse at about 26 % clay content. It is suggested that greater destabilization of inter-particle contacts caused by loss of matric suction on flooding was primarily responsible for the soil specimen containing the critical clay content of 26 % to exhibit maximum collapse potential. Increase in initial dry density, initial water content, clay content of the soil specimen and flooding pressure increased the time-duration of collapse of the compacted soil specimens. The time-duration of collapse was observed to range between 3 and 100 minutes for the tested specimens. Chapter 5 examines the influence of alternate wetting and drying on the collapse behaviour of compacted red soil specimens of Bangalore District. The compacted specimens were subjected to alternate wetting and drying cycles at surcharge pressures of 6.25 and 50 kPa in modified oedometer assemblies. Studies were also performed to examine whether the initial placement conditions have any bearing on the collapse behaviour of red soil specimens subjected to four cycles of wetting and drying. Mercury intrusion porosimetry was performed on a few desiccated red soil specimens. Experimental results showed that cyclic wetting and drying caused the desiccated specimens to exhibit similar or lower swell and collapse potentials than the compacted specimens. Such a behaviour resulted despite the desiccated specimens (specimens subjected to four cycles of wetting and drying are termed as desiccated specimens) possessing similar void ratios but much lower water contents than the compacted specimens. The restraining influence of the desiccation bonds and alteration of soil structure is considered responsible for the reduced swell and collapse tendencies of the desiccated specimens. The desiccation bonds imparted higher apparent preconsolidation pressures to the desiccated specimens. The initial compaction conditions also have a strong bearing on the collapse potentials of the desiccated specimens. Compacted red soil specimens subjected to cyclic wetting and drying under a higher surcharge pressure of 50 kPa exhibited larger swell potentials and lower collapse potentials than specimens desiccated at 6.25 kPa. Besides their lower void ratios, the presence of stronger desiccation bonds also contributed to their lower collapse potentials. The presence of stronger desiccation bonds in specimens desiccated under higher surcharge pressure was indicated by their higher apparent preconsolidation pressures. Chapter 6 examines the collapse behaviour of undisturbed red soil specimens from three locations in Bangalore District at a range of flooding pressures. Studies on the variations in initial water content and effect of remoulding on the collapse behaviour of the undisturbed specimens is supplemented by measuring the initial matric suction and performing mercury intrusion porosimetry experiments. Experimental results showed that based on their collapse potential at 200 kPa, the undisturbed red soils of Bangalore District classified as troublesome to moderately troublesome foundation soils. The bonded structure of the undisturbed red soil specimens imparted them higher apparent preconsolidation pressures and lower swell/collapse potentials than their remoulded counterparts. Variations in in-situ dry density, degree of saturation and relative distribution of pore sizes affected the matric suction and collapse potentials of the undisturbed specimens Chapter 7 summarizes the conclusions of this thesis.

AbstractThis chapter applies a practice-oriented, relational analytical approach to labour control regimes in GPNs to the empirical case of the Bangalore export-garment cluster. It illustrates how the labour control regime in the Bangalore export-garment cluster emerges from the intersection of six different sets of processual relations with the labour process: sourcing relations, wage relations, workplace relations, industrial relations, employment relations and labour market relations. For each set of relations, the chapter reveals the specific exploiting and disciplining practices performed by actors at various levels, which together constitute structural labour control relations. These practices include inter alia Bangalore garment managers’ production targeting, union-busting and wage theft practices, garment retailers’ predatory purchasing practices, and employers’ and state actors’ practices of constructing a complex multi-level training and migration regime to secure adequate labour supply. In the face of this complex mesh of labour control practices, the chapter highlights the various constraints and challenges for local garment unions to build and activate associational and institutional power resources.

In recent years, there has been growing recognition among researchers and policymakers that the quality of care provided by family planning (FP) programs in developing countries is an important determinant of whether couples adopt contraception and continue as contraceptive users, or whether these programs are underutilized. A major initiative to identify and implement improvements in the quality of services within the Indian program calls for a systematic analysis, organization, and presentation of the available data to the policymakers and program managers concerned. Additional data is also required on issues such as user's perception of quality of care, the relative importance of various components of quality of care, and quality of care from the provider's perspective. In response to these gaps in information, the Population Council commissioned a series of studies on the quality of services provided by the Indian government FP program and organized a workshop. This report synthesizes the findings of the 28 research papers presented at “The Quality of Services in the Indian Family Welfare Programme” workshop held in Bangalore from May 24–26, 1995.
