Ecological anthropology of households in East Madura, Indonesia
This dissertation is the result of diachronic and comparative anthropological study of rural households in Northeast Madura, Indonesia, carried out on eight separate visits between August 1985 and March 2009. The aim is to bring time-structured data to bear on key questions regarding the evolution of this rural community. My initial research from 1985 to 1987 focused on animal husbandry, household budgets, and time allocation, subjects central to Madurese society that had not been studied since well before Independence. I was interested in understanding more about Maduraâs high levels of poverty and notably how sedentary villagers could raise cows using a cut and carry mode of fodder collection in a savannah ecosystem prone to drought and without the benefit of communal grazing lands. The early focus on animal husbandry immediately expanded to cover all productive activities, which in turn raised questions about the value of children. A fertility study was undertaken to confirm what seemed to be unusually low fertility rates in comparison with other parts of Madura and Indonesia. The incoming data from the time allocation study provided a wealth of new questions on household consumption and expenditures, inter-household and inter-generational exchange, and social organization. Patron-client ties, high levels of violence, political, religious and secular networks and growing cash-cropping provided additional focus for intermediate trips to the field and a long-stay in 1995-1996. The study follows the comparative and diachronic research strategy advocated by many ecological anthropologists since Julian Steward. The ecological setting was a harsh one; the interrelationships people entertained with nature appeared to be complex and evolving. It appeared that Madurese agricultural ecology, household economy, fertility, religious practice, interpersonal violence, and other aspects of life would be better viewed as parts of a mutually-interacting system than as discreet elements detached from each other. The thesis adopts a problem-oriented perspective to build an explanatory framework for some of the critical questions regarding Madurese society. For example, I wanted to know what was keeping the Madurese poor, whether the well-known practice of racing bulls in pairs, and competing pairs of cows in beauty and agility contests had other functions in the society, and why Madura was considered a violent society. Historical research provided depth to the analysis to complement a set of one hundred case studies of violence collected in 1995-1996. Detailed analyses of the Madura cases, and the experience of violence in Kalimantan, presented elsewhere, are complemented by the findings from this study of household dynamics and the challenges its members face. For the roots of Madurese violence are found in the critical violent responses people on the edge of poverty can sometimes make when other avenues of redress are blocked. My overall objective is to tie together the specific ecology of the study village, the productive system, the economic challenges and the often dramatic social insecurity to the development, maintenance and transmission of household units over time. In trying to resolve each of the questions, the mechanism and the processes involved are equally, if not more important than solving the different conundrums that motivate the search in the first place. I found that the understanding and explanation of these Madurese cultural phenomena and processes were most parsimoniously advanced by systematic reference to material factors, processes and contingencies, and moreover that Madurese sentiments, values, ideologies and conceptual schemes were largely determined by these material constraints. The ecological approach (including such variants as cultural materialism and human ecology) having often been the subject of considerable controversy in Anthropology over the years, particularly in my home country of France, I devoted a great deal of the Introduction (Chapter One) to explicating the research strategyâs theoretical underpinnings, and notably to addressing the contentious issues of functionalism, teleology, system and holism. In Chapter Two, âHistorical Ecology of Madura and Gedang-Gedang,â I discuss the ecological and historical context in which Madurese communities on the island and in the local area of the field site village developed, particularly in light of the demands placed on rural communities by colonial and elite governments through taxes and forced deliveries. One of the effects of this structural violence, colonial wars and security force recruitment was the creation of the image of the violent Madurese, one that they are still trying to shake off. This and the agro-ecological system of maize cultivation and animal husbandry in a savannah ecosystem contribute to the organization of village communities characterized by dispersed settlement of households and household clusters and the development of self-help social institutions. Chapter Three, âOrganization and Exploitation of Domesticated Natureâ explores the various ways that villagers in Gedang-Gedang and the subdistrict Batuputih perceive and exploit their natural environment. Modalities of access to land are first discussed before examining ways in which locals conceptualize the plant and animal resources at their disposal, and the various uses to which they are put (in appendices). Plant and animal taxonomies are found to be pragmatic and utilitarian, a departure from early ethnoscience theorizing but congruent with more recent formulations. The rest of the chapter deals with the basic income-generating occupations available to villagers, calculating for each the returns to labour with the help of time allocation data and extensive interviews. An effort is made to chart diachronic trends, and show how access to certain high-earning activities is unequal. âSocial, Political and Religious Dynamicsâ (Chapter Four) presents the household concept used in this study and the composition of Gedang-Gedangâs conjugal units and the households they form based on a shared hearth. Religious and ritual structures and practices provide a glimpse of the institutions of social interaction that rhythm daily life in the village. Transitions occurring in the political arena are charted including changes since Reformasi. The chapter ends with an extended discussion of social control, first within the family, then within the wider community. Control is found to be exercised most strikingly, both in the village and in the town of Sumenep, in the practice of demanding and offering work through asymmetrical exchange, though most exchange is symmetrical between equals. Chapter Five on âHouseholds and Process,â deals with households, the location where adaptation takes place in concrete and observable ways. The goal in this chapter is to make the most of the longitudinal and comparative perspectives provided by the research to see through the analysis of actual cases how households develop over time, how they reproduce themselves, and how resilience and vulnerability can come to characterize them at different stages in time. Simple dependency ratios and consumer-producer values for 44 households are plotted over the 24 years of the study to demonstrate the low overall rates found for most households in Gedang-Gedang, with occasional high rates a sign of poverty or crisis. Household consolidation or fission appears usually to be caused by economic and reproductive (child-raising) factors, though in not a few instances conflicts, exacerbated by economic and other inequalities, play a role. Households are plotted on time scales showing progression (or regression) of landholding and livestock over time, and divided into groups of wealthy, poor, or âhave enoughs.â The analysis then shifts to examining individual household histories to obtain a more palpable idea of how they develop in specific directions over time. Among the generalities that can be drawn is the importance of labour, particularly the retaining of oneâs child in the tanĂšan and the obtaining of a son- or daughter-in-law that will augment the householdâs productive capacity. This ability to retain children and attract their spouses is one that is not equally shared; wealthy households are usually favoured in this regard. Food and other consumption and exchange data augmented with interview data pointed to important variations in nutrition over the yearly agricultural cycle. Exchange of food and other resources in Gedang-Gedang appears to serve principally to cement social relations among kin and neighbours, or to compensate for work done. The data from Gedang-Gedang points to highly symmetric exchange practices, except in the case of âwork for food,â religious and ritual exchange. Lifecycle exchanges have the effect of smoothing over the otherwise significant perturbations in the day to day lives of families when members enter and leave the household, be it the result of marriage, birth or death. As it constitutes a form of exchange, the institution of raising prime cows and bulls for competitive purposes is treated in this chapter, highlighting the positive feedback from these sports to village animal husbandry. In concluding the analysis of individual household economic trajectories, Marten Schefferâs model of the poverty trap (Scheffer 2009) was readily applicable. My presentation of Gedang-Gedang households concluded with Chapter Six on âFertility.â The data showed very low average fertility for Gedang-Gedang in comparison with other villages studied with similar methods in Madura and Java. The conclusions and indicators from the fertility study in Gedang-Gedang strongly validate the findings of Benjamin Whiteâs well-known study of high fertility in the village of Kali Loro, Central Java, though the contexts differ in key respects. I conclude that the particular ecological and economic context of Gedang-Gedang encourages women to self-regulate fertility rather stringently. The salient elements of this context are the relative paucity of income-producing employment for children, the small size of landholdings, and the particular constraints of cut and carry cow husbandry. In evaluating the hypotheses initially enunciated at the beginning of the study in light of the data collection and analysis it is found that: - Differential adaptation of village households can be accounted for in large part by theories and principles from general ecology. This provides validation for the use of ecological models in anthropology; - Different limiting factors in each part of the village are responsible for different economic adaptations, which evolve as opportunities change; - Time allocation and the use of time-structured data provide information about the behaviour of households and individuals that is not obtainable from classical ethnographic methods, and that has important implications for comparative studies of the value of children; - The poorest households are usually unable to obtain the credit necessary to engage in high risk but potentially high return occupations such as tobacco planting but some poor and almost all other villagers in appropriate agricultural zones do accept high risk under certain circumstances as the only way to obtain high income. Risk avoidance explains the refusal of villagers to plant high yielding varieties of maize; - The propensity of Madurese on the island of Madura to engage in violent interpersonal attacks is best understood in relation to struggles over material resources; - âThe rich get richer, the poor get poorerâ as a general trend is validated for the village, and the reasons are linked to initial conditions of wealth to a much greater extent than to other personal traits. Providing diachronic and comparative data from a rural Indonesian community, the study contributes to supporting general ecological theories. The study concludes that ecology and anthropology may well work better conjoined than either of them does alone.</p
Investigation of stratiform sulphide mineralisation at Meall Mor, South Knapdale, Argyll
A co-ordinated geochemical-geophysical-geological investigation of copper
mineralisation in the Meal1 ?46r area, South Knapdale, Argyll was carried 0th
in 1976 and followed by a drilling programme of 3 shallow holes in early 1977.
The mineralisation occursin a zone of weak stratiform sulphide mineralisation
(the pyrite zone) with a strike length of 1Okm in the Upper &ins Quartz&e
of the Middle Dalradian.
The geochemical drainage survey showed the existence of a strongly anomalous
distribution of Cu and Sb in the Abhainn Srathain draining south from .
Meal1 M&- and detailed soil sampling over the pyrite zone outlined a broad
area enriched in copper. Deeper soil sampling confirmed the anomalously
high copper values and a coincident IP anomaly was found stretching from
Meal1 M& south to the old mine workings on Abhainn Srathain, and is probably
caused by a local enrichment of pyrite and chalcopyrite within the pyrite
zone.
Three boreholes were drilled; two on coincident geochemical and geophysical
anomalies, and the third beneath the old mines at Abhainn Srathain. Copper
values in the first two holes range up to 0.24% Cu over 4.27m, but up to
1.06% Cu over 2.67m in the third and this enrichment may be related to a
later remobilisation of the disseminated chalcopyrite. The results of subsequent
drilling at two other sites are given in Appendix III

The associations of interleukin-6 (IL-6) and downstream inflammatory markers with risk of cardiovascular disease: the Caerphilly Study
Lattice-switch Monte Carlo
We present a Monte Carlo method for the direct evaluation of the difference
between the free energies of two crystal structures. The method is built on a
lattice-switch transformation that maps a configuration of one structure onto a
candidate configuration of the other by `switching' one set of lattice vectors
for the other, while keeping the displacements with respect to the lattice
sites constant. The sampling of the displacement configurations is biased,
multicanonically, to favor paths leading to `gateway' arrangements for which
the Monte Carlo switch to the candidate configuration will be accepted. The
configurations of both structures can then be efficiently sampled in a single
process, and the difference between their free energies evaluated from their
measured probabilities. We explore and exploit the method in the context of
extensive studies of systems of hard spheres. We show that the efficiency of
the method is controlled by the extent to which the switch conserves correlated
microstructure. We also show how, microscopically, the procedure works: the
system finds gateway arrangements which fulfill the sampling bias
intelligently. We establish, with high precision, the differences between the
free energies of the two close packed structures (fcc and hcp) in both the
constant density and the constant pressure ensembles.Comment: 34 pages, 9 figures, RevTeX. To appear in Phys. Rev.
Measurements of Scintillation Efficiency and Pulse-Shape for Low Energy Recoils in Liquid Xenon
Results of observations of low energy nuclear and electron recoil events in
liquid xenon scintillator detectors are given. The relative scintillation
efficiency for nuclear recoils is 0.22 +/- 0.01 in the recoil energy range 40
keV - 70 keV. Under the assumption of a single dominant decay component to the
scintillation pulse-shape the log-normal mean parameter T0 of the maximum
likelihood estimator of the decay time constant for 6 keV < Eee < 30 keV
nuclear recoil events is equal to 21.0 ns +/- 0.5 ns. It is observed that for
electron recoils T0 rises slowly with energy, having a value ~ 30 ns at Eee ~
15 keV. Electron and nuclear recoil pulse-shapes are found to be well fitted by
single exponential functions although some evidence is found for a double
exponential form for the nuclear recoil pulse-shape.Comment: 11 pages, including 5 encapsulated postscript figure
Extensional rupture of model non-Newtonian fluid filaments
We present molecular dynamics computer simulations of filaments of model
non-Newtonian liquid stretched in a uniaxial deformation to the point of
breaking. The liquid consists of Lennard-Jones monomers bound into chains of
100 monomers by nonlinear springs, and several different constant velocity and
constant strain rate deformations are considered. Generally we observe
nonuniform extensions originating in an interplay between the stretching forces
and elastic and capillary restoring mechanisms, leading to highly uneven shapes
and alternating stretched and unstretched regions of liquid. Except at the
fastest pulling speeds, the filaments continue to thin indefinitely and break
only when depleted of molecules, rather than common viscoelastic rupture
mechanisms.Comment: 7 pages text, 14 pages (eps) figure
Challenges of open innovation: the paradox of firm investment in open-source software
Open innovation is a powerful framework encompassing the generation, capture, and employment of intellectual property at the firm level. We identify three fundamental challenges for firms in applying the concept of open innovation: finding creative ways to exploit internal innovation, incorporating external innovation into internal development, and motivating outsiders to supply an ongoing stream of external innovations. This latter challenge involves a paradox, why would firms spend money on R&D efforts if the results of these efforts are available to rival firms? To explore these challenges, we examine the activity of firms in opensource software to support their innovation strategies. Firms involved in open-source software often make investments that will be shared with real and potential rivals. We identify four strategies firms employ â pooled R&D/product development, spinouts, selling complements and attracting donated complements â and discuss how they address the three key challenges of open innovation. We conclude with suggestions for how similar strategies may apply in other industries and offer some possible avenues for future research on open innovation
Influence of the 6^1S_0-6^3P_1 Resonance on Continuous Lyman-alpha Generation in Mercury
Continuous coherent radiation in the vacuum-ultraviolet at 122 nm
(Lyman-alpha) can be generated using sum-frequency mixing of three fundamental
laser beams in mercury vapour. One of the fundamental beams is at 254 nm
wavelength, which is close to the 6^1S_0-6^3P_1 resonance in mercury.
Experiments have been performed to investigate the effect of this one-photon
resonance on phasematching, absorption and the nonlinear yield. The efficiency
of continuous Lyman-alpha generation has been improved by a factor of 4.5.Comment: 8 pages, 7 figure
