Birth of the European individual : Outline of a theory of legal practice

The modern subject is what we can call a self-subjecting individual. This is someone in whose inner reality has been implanted a more permanent governability, a governability that works inside the agent. Michel Foucault s genealogy of the modern subject is the history of its constitution by power practices. By a flight of imagination, suppose that this history is not an evolving social structure or cultural phenomenon, but one of those insects (moth) whose life cycle consists of three stages or moments: crawling larva, encapsulated pupa, and flying adult. Foucault s history of power-practices presents the same kind of miracle of total metamorphosis. The main forces in the general field of power can be apprehended through a generalisation of three rationalities functioning side-by-side in the plurality of different practices of power: domination, normalisation and the law. Domination is a force functioning by the rationality of reason of state: the state s essence is power, power is firm domination over people, and people are the state s resource by which the state s strength is measured. Normalisation is a force that takes hold on people from the inside of society: it imposes society s own reality its empirical verity as a norm on people through silently working jurisdictional operations that exclude pathological individuals too far from the average of the population as a whole. The law is a counterforce to both domination and normalisation. Accounting for elements of legal practice as omnihistorical is not possible without a view of the general field of power. Without this view, and only in terms of the operations and tactical manoeuvres of the practice of law, nothing of the kind can be seen: the only thing that practice manifests is constant change itself. However, the backdrop of law s tacit dimension that is, the power-relations between law, domination and normalisation allows one to see more. In the general field of power, the function of law is exactly to maintain the constant possibility of change. Whereas domination and normalisation would stabilise society, the law makes it move. The European individual has a reality as a problem. What is a problem? A problem is something that allows entry into the field of thought, said Foucault. To be a problem, it is necessary for certain number of factors to have made it uncertain, to have made it lose familiarity, or to have provoked a certain number of difficulties around it . Entering the field of thought through problematisations of the European individual human forms, power and knowledge one is able to glimpse the historical backgrounds of our present being. These were produced, and then again buried, in intersections between practices of power and games of truth. In the problem of the European individual one has suitable circumstances that bring to light forces that have passed through the individual through centuries.

The Biopolitics of Gender

This dissertation inquires into the relationship between gender and biopolitics. Biopolitics, according to Michel Foucault, is the mode of politics that is situated and exercised at the level of life. The dissertation claims that gender is a technology of biopower specific to the optimisation of the sexual reproduction of human life, deployed through the scientific and governmental problematisation of declining fertility rates in the mid-twentieth century. Just as Michel Foucault claimed that sexuality became a scientific and political discourse in the nineteenth century, gender has also since emerged in these fields. In this dissertation, gender is treated as neither a representation of sex nor a cultural construct or category of identity. Rather, a genealogy of gender as an apparatus of biopower in conducted. It demonstrates how scientific and theoretical developments in the twentieth century marshalled gender into the sex/sexuality apparatus as a new technology of liberal biopower. Gender, I argue, has become necessary for the Western liberal order to recapture and re-optimise the life-producing functions of sex that reproduce the very object of biopolitics: life. The concept of the life function is introduced to analyse the life-producing violence of the sex/sexuality/gender apparatus. To do this, the thesis rereads the work of Michel Foucault through Gilles Deleuze for a deeper grasp of the material strategies of biopower and how it produces categories of difference and divides population according to them. The work of Judith Butler, in turn, is used as a foil against which to rearticulate the question of how to examine gender genealogically and biopolitically. The dissertation then executes a genealogy of gender, tracing the changing rationalities of sex/sexuality/gender from early feminist thought, through mid-twentieth century sexological, feminist, and demographic research, to current EU policy. According to this genealogy, in the mid-twentieth century demographers perceived that sexuality/sex, which Foucault observed as the life-producing biopolitical apparatus, was no longer sufficiently disciplining human bodies to reproduce. The life function was escaping the grasp of biopower. The analysis demonstrates how gender theory was taken up as a means of reterritorialising the life function: nature would be disciplined to reproduce by controlling culture. The crucial theoretical and genealogical argument of the thesis, that gender is a discourse with biopolitical foundations and a technology of biopower, radically challenges the premises of gender theory and feminist politics, as well as the emancipatory potential often granted to the gender concept. The project asks what gender means, what biopolitical function it performs, and what is at stake for feminist politics when it engages with it. In so doing, it identifies biopolitics and the problem of life as possibly the most urgent arena for feminist politics today.

Hämeenlinnan lääkäripiirin koulutetut kätilöt vallan rakenteissa 1879 - 1920

Tässä pro gradu -tutkimuksessa tutkin kätilötyön rakentumista Suomessa vuosina 1879 - 1920 Hämeenlinnan lääkäripiirin näkökulmasta. Analysoin vuoden 1879 kätilöohjesäännön tuomien muutosten sekä valtion organisaatioiden, lääkäreiden ja kunnallistason määräysten merkitystä kätilötoiminnalle ja kätilöille. Tutkimuksen ajallinen rajaus, 1879 - 1920, juontuu Keisarillisen Majesteetin vuonna 1879 antamasta kätilöohjesäännöstä, joka oli toimintaa ohjaavana lainsäädäntönä voimassa vuoteen 1920. Tutkin tässä työssä kätilötyötä kahdessa tasossa, mikrohistoriallisesti ja yleisellä tasolla. Tutkimusmenetelmänä sovellan kvalitatiivista ja kvantitatiivista menetelmää. Tutkimuksen teoreettisena kehyksenä toimii soveltavin osin Michel Foucault'n teoria biovallasta. Kätilöiden puutteeseen maalaiskunnissa oli pyritty vaikuttamaan vuoden 1859 kätilöohjesäännöllä. Käytännön muutoksia ei tapahtunut ja vuonna 1879 hyväksyttiin uusi kätilöohjesääntö. Uusi ohjesääntö oli valtion hallinnon ja lääkäreiden yhteistoiminnan tulos. Sen sanoma oli ohjaavaa, mutta ei pakottavaa. Lakiuudistuksella pyrittiin vaikuttamaan kuntiin ja kuntien kautta kansalaisten toimintaan. Haluttiin muokata ihmisten käyttäytymistapoja normalisoimalla kätilöhoitoinen synnytys. Kätilöohjesäännön voimaantulo ja vuodet 1879 - 1920 voidaan nähdä käännekohtana kätilötyössä. Tutkimusperiodin aikana kätilötyö alkoi saada itsenäisen ammattikunnan piirteitä selvemmin. Rahan rooli oli monessa suhteessa merkittävä, sillä elatuksen lisäksi raha vaikutti kätilön asemaan ja arvostukseen. Kunnan päättäjät olivat merkittävässä valtaapitävässä asemassa, koska heillä oli päätösvalta kätilön palkkaamisessa ja työn ehdoissa. Kunnissa, joissa kätilöä arvostettiin, maksettiin paremmin ja kuntalaiset tukeutuivat koulutettuun apuun enemmän. Tutkimusaikana kätilöiden olosuhteet kunnissa olivat haasteelliset eikä laki rajoittanut synnytyksen avustajaa, joten kätilöhoitoisissa synnytyksissä tapahtunut kasvu oli kätilöiden melko pyytettömän työn tulosta. Haluttiin muutakin kun käyttää valtaa.

"Totta kai pyrin koko ajan tuntemaan oman kroppani siellä" : Kolmen orkesteriviulistin kokemuksia ruumiillisuudestaan.

Tutkielmassa esitellään kolmen orkesteriviulistin kokemuksia ja käsityksiä omasta ruumiillisuudestaan muusikon työssään. Muusikkolähtöisyys, laajemmin tarkasteltuna tekijälähtöinen tutkimus, on nykyisin yhä tärkeämpi osa musiikintutkimusta. Muusikkolähtöistä tutkimusta on Suomessakin kirjoitettu jonkin verran, harvoin kuitenkaan ruumiillisuusteeman kautta. Haastatellut viulistit ovat pääkaupunkiseudun suurista orkestereista. Muusikon työtä voidaan tarkastella monista eri lähtökohdista. Tässä työssä pyritään ottamaan huomioon ihmisen oma kokemus ja ruumiillinen sidos maailmaan, ja näin se sitoutuu fenomenologisiin lähtökohtiin, erityisesti Maurice Merleau-Pontyn ajatteluun. Michel Foucault ja Elizabeth Grosz edustavat tämän työn kannalta sitä ajattelutapaa, jonka hengessä pidän muusikon työtä historiallisesti rakentuneena ja muutoksenalaisena prosessina. Groszin teoretisointi keskittyy subjektin ruumiillisuuteen ja tapoihin käsitteellistää ruumis länsimaisessa ajattelussa. Haastattelumateriaali jakaantuu kahteen päälukuun. Ensimmäisessä käsitellään soittajien omaa yksityistä tilaa. Harjoittelun oma tila liittyy ruumiillisuuteen sikäli, että ruumiillinen toistotyö ja viulistisen identiteetin muotoutuminen tapahtuu pitkälti yksityisesti, tietoisena julkisen tilan vaatimuksista. Orkesteriviulistien sosiaaliseen tilaan liittyy toisaalta vuorovaikutus muiden muusikoiden kanssa harjoituksissa ja toisaalta muusikoiden ja yleisön kohtaaminen konserteissa. Sosiaaliseen tilaan liittyviä ruumiillisuuteen kytkeytyviä ilmiöitä käsitellään erillään, toisessa analyysiluvussa. Tutkielma tuo esiin välähdyksiä erilaisista ruumiillisuuteen ja viulunsoittoon kytkeytyvistä ilmiöistä. Kvalitatiivisen ja fenomenologisen tutkimuksen hengessä haastateltujen erilaiset kokemukset on pyritty esittelemään pyrkimättä universalisoimaan niitä. Haastattelumateriaali osoittaa viulistisen ruumiillisuuden liittyvän merkittävällä tavalla muusikkojen käsityksiin itsestään. Haastateltujen kokemukset tuovat lisää tietoa orkesteriviulistin työstä.

Producing interactivity : Does media convergence promote interactivity and audience participation?

This study investigates the process of producing interactivity in a converged media environment. The study asks whether more media convergence equals more interactivity. The research object is approached through semi-structured interviews of prominent decision makers within the Finnish media. The main focus of the study are the three big ones of the traditional media, radio, television and the printing press, and their ability to adapt to the changing environment. The study develops theoretical models for the analysis of interactive features and convergence. Case-studies are formed from the interview data and they are evaluated against the models. As a result the cases arc plotted and compared on a four-fold table. The cases are Radio Rock, NRJ, Biu Brother, Television Chat, Olivia and Sanoma News. It is found out that the theoretical models can accurately forecast the results of the case studies. The models are also able to distinguish different aspects of both interactivity and convergence so that a case, which at a first glance seems not to be very interactive is in the end found out to receive second highest scores on the analysis. The highest scores are received by Big Brother and Sanoma News. Through the theory and the analysis of the research data it is found out that the concepts of interactivity and convergence arc intimately intertwined and very hard in many cases to separate from each other. Hence the answer to the main question of this study is yes, convergence does promote interactivity and audience participation. The main theoretical background for the analysis of interactivity follows the work of Came Fleeter, Spiro Kiousis and Sally McMillan. Heeler's six-dimensional definition of interactivity is used as the basis for operationalizing interactivity. The actor-network theory is used as the main theoretical framework to analyze convergence. The definition and operationalization of the actor-network theory into a model of convergence follows the work of Michel Callon. Bruno Latour and especially John Law and Felix Stalder.

Tunne, taistele tai taivu : synnytys ja valta Foucault'n näkökulmasta verkkokeskustelussa

Kun synnytyksessä mikään ei suju suunnitelmien mukaan, mistä oikeastaan on kysymys? Kenellä on valta synnytyksessä ja miten se jaetaan? Pro gradu -työssäni yritän ratkaista tätä oman pettymykseni herättämää kysymystä Michel Foucault'n valtakäsityksien avulla. Työlleni erityisen tärkeitä ovat ranskalaisfilosofin teoriat vallan osapuolten välisistä kamppailuista, vallan ja tiedon suhteesta sekä vallasta mahdollisuuksien hallintana. Foucault'sta inspiroituneilta hallinnan analyytikoilta Nikolas Roselta ja Mitchell Deanilta saan käytännön apua analyysin tekemiseen aineistolähtöisen tulkinnan keinoin. Heidän neuvostaan keskityn miten-kysymyksiin sekä sanoihin asioiden mahdollistajana. Aineistonani käytän erään aktiivisuutta ja luottamuksellisuutta vaalivan keskustelupalstan Synnyttäjän oikeudet -aiheista keskustelua. Analyysin alku nosti keskustelusta kolme selkeää tapaa synnytyksen ja vallan hahmottamiseen: luonnon ja synnyttäjän voimia korostavan, taisteluasennetta kannattavan sekä sopuisaa, tyydyttävää elämystä toivovan. Tämä on kuitenkin vasta johtolanka, jonka seuraamisessa tarvitsen tutkimuskirjallisuutta sekä teoreettisen viitekehyksen tukea. Tärkeimpiä hyödyntämiäni tekstejä ovat Foucault'n The Subject and Power (2000a) ja Truth and Power (2000b) sekä synnyttämisen mahdollisuuksia pohtivat teokset, kuten Johanna Ruusuvuoren Synnyttämisen suuntia (1992) ja Robbie Davis-Floydin ja Carolyn Sargentin toimittama Childbirth and Authoritative Knowledge (1997). Teorian, tutkimustulosten ja aineistoni perusteella väitän, että synnytyksen ja vallan suhteessa on kysymys auktoriteetin ja itsehallinnan erilaisista kohtaamistavoista. Tiedon ja vallan järkähtämätön suhde on pönkittänyt synnytyssalin auktoriteeteille tukevan aseman, jota ei helposti heiluteta. Yrittää silti voi ja pitääkin, ainakin keskustelijoideni mielestä. Naiset synnyttävät uusia kansalaisia lääketieteen valvonnassa, mutta he tekevät sen omillakin ehdoillaan, omien tavoitteidensa toteuttamiseksi. Verkon kautta synnytyksen vaihtoehdot ovat levinneet ja jättäneet jälkensä myös perinteisen synnytyskulttuurin pintaan. Yksien totuudet ovat kuitenkin toisten totuuksia arvokkaampia, kuten Tammisaaren synnytysosaston sulkeminen osoittaa.

Kansan raittiudeksi ja kotien onneksi : Naisten kieltolakimielipiteet ja toiminta kieltolain puolesta ja sitä vastaan 1919 - 1932

It is often maintained that the Prohibition Act (in force from 1 June 1919 to 5 April 1932) still influences both the Finnish alcohol policy and notions about alcohol. This study focuses on the development of women s opinions concerning Prohibition in Finland. What role did the formulation and expression of women s opinions and women's actions play in the final outcome of the Prohibition Act? What do the debate on Prohibition and women s activities for and against the legislation tell us about the status and possibilities of women to exert influence in the Finnish society of the Prohibition era? Women s opinions are particularly interesting since they deviated radically from what has generally been assumed. It was expected that the referendum of 1931 would result in a resounding vote of 100% in favour of Prohibition, but the outcome was a majority vote against it. Over 65% of the women who cast their vote in the referendum wanted a full repeal of Prohibition. The study approaches the history of Prohibition by combining methods and theories of the history of mentalities and social history with gender history. Women are examined as a heterogeneous group with dissimilar objectives and differing ways of acting and thinking. The research material consists of press materials, archival materials from organisations, personal materials and statistics from the Prohibition period. Both discourses and practices are examined; the object of the research is best described by Michel Foucault's concept of dispositif. When participating in the public debate on Prohibition, women based their right to express their opinions and take part in action on an ideological continuum spanning a hundred years, according to which home and family were central areas of women s interest. This idea was linked to questions of morality and social policy. On the other hand, women presented themselves as working taxpayers, voters and equal citizens. The most crucial issue in women's discussions was whether Prohibition improved or worsened the temperance of fathers, husbands and sons. The dichotomies town dweller - countryside dweller, Swedish-speaking Finnish-speaking, and middle class - working class were highly significant backgrounds both as factors dividing women and in public discussions regarding Prohibition. The 1931 referendum showed that the lines of demarcation drawn during the preceding debate did not materialise in political action in line with these dichotomies: the dispositif did not correspond to the discourse. Contrary to what was expressed in public, a great number of women among the labour and rural classes, among inland inhabitants and among Finnish-speakers were also against Prohibition. The media and organisations defended temperance and Prohibition almost until the end of the Prohibition era. This discourse was in conflict with the discourse of everyday conversations and practices in which alcohol was present.

Structure and properties of Tl0.5Pb0.5Sr2Gd2−xCexCu2O9−δ

A systematic study of the Tl0.5Pb0.5Sr2Gd2−xCexCu2O9−δ system has revealed the existence of a pure phase in the compositional. range 0.0≤x≤0.6 crystalizzing in the 1222 structure. It has an intersheet distance of approximately 6 Å, a value much higher than those found in other cuprates with double CuO2 sheets interleaved by a single fluorite layer. Superconductivity has been observed in the range 0.1≤x≤0.4 with a Tc of 45 K and a superconductive volume fraction up to 20% for the optimal composition. An interesting variation of the superconducting properties of the above system with the composition, i.e. cerium content, has also been noticed. A possible dependence of superconductivity on the coupling between CuO2 sheets in the layered cuprates has been pointed out to bring out a correlation between structure and properties.

The top 100 questions of importance to the future of global agriculture

Despite a significant growth in food production over the past half-century, one of the most important challenges facing society today is how to feed an expected population of some nine billion by the middle of the 20th century. To meet the expected demand for food without significant increases in prices, it has been estimated that we need to produce 70-100 per cent more food, in light of the growing impacts of climate change, concerns over energy security, regional dietary shifts and the Millennium Development target of halving world poverty and hunger by 2015. The goal for the agricultural sector is no longer simply to maximize productivity, but to optimize across a far more complex landscape of production, rural development, environmental, social justice and food consumption outcomes. However, there remain significant challenges to developing national and international policies that support the wide emergence of more sustainable forms of land use and efficient agricultural production. The lack of information flow between scientists, practitioners and policy makers is known to exacerbate the difficulties, despite increased emphasis upon evidence-based policy. In this paper, we seek to improve dialogue and understanding between agricultural research and policy by identifying the 100 most important questions for global agriculture. These have been compiled using a horizon-scanning approach with leading experts and representatives of major agricultural organizations worldwide. The aim is to use sound scientific evidence to inform decision making and guide policy makers in the future direction of agricultural research priorities and policy support. If addressed, we anticipate that these questions will have a significant impact on global agricultural practices worldwide, while improving the synergy between agricultural policy, practice and research. This research forms part of the UK Government's Foresight Global Food and Farming Futures project.

Is O-1(2) alone sufficient for DNA cleavage? Possible involvement of paramagnetic intermediates

It is proposed that singlet dioxygen reacting with guanosine or deoxyguanosine part of nucleotides does not, by itself, cause DNA cleavage. The strand break originates at the endoperoxide stage whenever this link evolves into a O-centered radical. The O-centered radical is then in a good spatial position to abstract an hydrogen intramolecularly from the ribose or desoxyribose part of the nucleotide. The carbon centered radical thus formed on the sugar part may lead to strand break either by a p-scission mechanism or by an homolytically induced solvolysis. High pH could also induce cleavage after the endoperoxide stage via a base catalyzed ring chain protomerism.

Averting biodiversity collapse in tropical forest protected areas

The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon(1-3). With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental stresses(4-9). As pressures mount, it is vital to know whether existing reserves can sustain their biodiversity. A critical constraint in addressing this question has been that data describing a broad array of biodiversity groups have been unavailable for a sufficiently large and representative sample of reserves. Here we present a uniquely comprehensive data set on changes over the past 20 to 30 years in 31 functional groups of species and 21 potential drivers of environmental change, for 60 protected areas stratified across the world's major tropical regions. Our analysis reveals great variation in reserve `health': about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally. Habitat disruption, hunting and forest-product exploitation were the strongest predictors of declining reserve health. Crucially, environmental changes immediately outside reserves seemed nearly as important as those inside in determining their ecological fate, with changes inside reserves strongly mirroring those occurring around them. These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.

Intravenous immunoglobulin expands regulatory T cells via induction of cyclooxygenase-2-dependent prostaglandin E2 in human dendritic cells

CD4(+)CD25(+)FoxP3(+) regulatory T cells (Tregs) play a critical role in the maintenance of immune tolerance. Intravenous immunoglobulin (IVIg), a therapeutic preparation of normal pooled human IgG, expands Tregs in various experimental models and in patients. However, the cellular and molecular mechanisms by which IVIg expands Tregs are relatively unknown. As Treg expansion in the periphery requires signaling by antigen-presenting cells such as dendritic cells (DCs) and IVIg has been demonstrated to modulate DC functions, we hypothesized that IVIg induces distinct signaling events in DCs that subsequently mediate Treg expansion. We demonstrate that IVIg expands Tregs via induction of cyclooxygenase (COX)-2-dependent prostaglandin E2 (PGE(2)) in human DCs. However, costimulatory molecules of DCs such as programmed death ligands, OX40 ligand, and inducible T-cell costimulator ligands were not implicated. Inhibition of PGE(2) synthesis by COX-2 inhibitors prevented IVIg-mediated Treg expansion in vitro and significantly diminished IVIg-mediated Treg expansion in vivo and protection from disease in experimental autoimmune encephalomyelitis model. IVIg-mediated COX-2 expression, PGE(2) production, and Treg expansion were mediated in part via interaction of IVIg and F(ab('))(2) fragments of IVIg with DC-specific intercellular adhesion molecule-3-grabbing nonintegrin. Our results thus uncover novel cellular and molecular mechanism by which IVIg expands Tregs.

The adenylyl cyclase Rv2212 modifies the proteome and infectivity of Mycobacterium bovis BCG

All organisms have the capacity to sense and respond to environmental changes. These signals often involve the use of second messengers such as cyclic adenosine monophosphate (cAMP). This second messenger is widely distributed among organisms and coordinates gene expression related with pathogenesis, virulence, and environmental adaptation. Genomic analysis in Mycobacterium tuberculosis has identified 16 adenylyl cyclases (AC) and one phosphodiesterase, which produce and degrade cAMP, respectively. To date, ten AC have been biochemically characterized and only one (Rv0386) has been found to be important during murine infection with M. tuberculosis. Here, we investigated the impact of hsp60-driven Rv2212 gene expression in Mycobacterium bovis Bacillus Calmette-Guerin (BCG) during growth in vitro, and during macrophage and mice infection. We found that hsp60-driven expression of Rv2212 resulted in an increased capacity of replication in murine macrophages but an attenuated phenotype in lungs and spleen when administered intravenously in mice. Furthermore, this strain displayed an altered proteome mainly affecting proteins associated with stress conditions (bfrB, groEL-2, DnaK) that could contribute to the attenuated phenotype observed in mice.

Long-term effects of Macroternies termites, herbivores and annual early fire on woody undergrowth community in Sudanian woodland, Burkina Faso

Termites, herbivores and fire are recognized as major guilds that structure woody plant communities in African savanna and woodland ecosystems. An understanding of their interaction is crucial to design appropriate management regimes. The aim of this study was to evaluate the long-term impacts of herbivore, fire and termite activities on regeneration of trees. Permanent experimental quadrats were established in 1992 in the Sudanian woodland of Burkina Faso subjected to grazing by livestock and annual early fire and the control. Within the treatment quadrats, an inventory of the woody undergrowth community was conducted on termitaria occupied by Macrotermes subhyalinus, extended termitosphere (within 5 m radius from the mound base) and adjacent area (beyond 5 m from the mound base). Hierarchical analysis was performed to determine significant differences in species richness, abundance and diversity indices among vegetation patches within fire and herbivory treatments. Grazed quadrats had significantly (P < 0.001) more species and stem density of woody undergrowth than non-grazed quadrats but maintained similar level of species richness and stem density of woody undergrowth on termitaria. There were not significant differences (P>0.05) in species richness and stem density between burnt and unburnt quadrats. Termitaria supported a highly diverse woody undergrowth with higher stem density than either the extended termitosphere or rest of quadrats. The density of woody undergrowth was significantly related with mature trees of selected species on termitaria (R-2 = 0.593; P<0.001) than that on the extended termitosphere (R-2 = 0.333; P<0.001) and adjacent area (R-2 = 0.197; P<0.001). It can be concluded that termites facilitate the regeneration of woody species while grazing and annual early fire play a minor role in the regeneration of woody species. The current policy that prohibits grazing should be revised to accommodate the interests of livestock herders. (C) 2014 Elsevier GmbH. All rights reserved.
