Efraim Syyrialaisen luostari: Tapausesimerkkejä munkkien luostariin vetäytymisen syistä

Tutkielma on kaksivaiheinen. Ensin esittelen apostolisen, Syyrialaisortodoksisen kirkon historiaa ja luostariperinnettä. Toisen osan tarkoitus on selvittää, liittyykö Pyhän Efraim Syyrialaisen luostarin munkkien luostariinjäämispäätökseen yhteiskunnallisia syitä ja mitä muita mahdollisia syitä voidaan löytää. Vertailen lopuksi varhaisia, 400-luvulla eläneiden kilvoittelijoiden Pyhän Efraim Syyrialaisen, Antonius Suuren ja Simeon Pylväspyhimyksen motiiveita nykykilvoittelijoiden motiiveihin, sikäli kuin se on mahdollista. Selvitän myös, onko Efraim Syyrialaisen esimerkillä ollut merkitystä nykykilvoittelijoille. Empiirinen aineisto kerättiin kahtena vuotena v. 2002 ja 2003. Tutkielmaa varten haastattelin kolmea Efraim Syyrialaisen luostarin munkkia. Pääinformanttini oli ko. luostarin seminaarin teologiopiskelija. Heidän kotitaustansa on syyrialaisortodoksinen, voimakkaasti uskonnollinen. Spiritualiteettia harjoitettiin jo lapsuudessa sekä kotona että kirkossa. Tutkielmani näkökulma on uskontohistoriallinen ja uskontososiologinen. Tutkin miten varhaiset- sekä nykypäivän kilvoittelijat ovat suhtautuneet yhteiskuntaan ja miten he ovat integroituneet luostariinsa. Kysymyksessä on nykypäivän osalta laadullinen tapaustutkimus, jonka metodeina ovat teemahaastattelu, jonka yhtenä osana olivat argumentit ja osallistruva havainnointi. Analysoin vastaukset sisällön analyysiä käyttäen. Haastatellut munkit korostivat syyrian kielen ja tradition opiskelun ja sen siirtämisen tärkeyttä seminaariin opiskelemaan hakeutumisensa, ja sen jälkeen munkiksi jäämisensä perusteluna. Pyhän Efraim Syyrialaisen esimerkin munkit kokivat olevan heille hyvin tärkeän tradition siirtäjän. Opiskelemisen ja matkustamisen mahdollisuus munkkina koettiin myös tärkeänä ja siitä syystä luostariin jäätiin, eli yhteiskunnallinen syy löytyi. Sisällön analyysissä ilmeni, että alkujaan koti edusti munkille primaarista tekijää. Sekundääristä tekijää edustivat kirkkoon kuuluva ryhmä, munkit ja luostari. Kodin ja kirkossa käynnin seurauksena tradition ja syyrian kielen oppimisen halu korostui ja niitä haluttiin lähteä opiskelemaan. Positiiviseksi viiteryhmäksi tällöin muodostuivat seminaariopiskelun aikana munkit ja muut luostarin asukkaat. Luostariin jäämisensä jälkeen primaarin tekijän voidaan huomata vaihtuneen luostariksi ja kodin asema on jäänyt sekundaariseksi. Yhteys luostarin ja ympäröivän yhteiskunnan kanssa tapahtui varhaisena aikana pääasiallisesti siten, että ihmiset tulivat kilvoittelijan luokse. Nykymunkit puolestaan käyvät niiden seurakuntalaisten kotona, jotka eivät pääse yhteisiin jumalanpalveluksiin ja auttavat heitä sielunhoidollisesti ja tarvittaessa taloudellisesti. Kirkon patriarkka Mar Ignatios Zakka I Iwasilla ja metropoliitta Eusthatios Matta Rohamilla on paljon yhteyksiä myös islaminuskoiseen väestönosaa Syyriassa. Ekumeenisia yhteyksiä on munkeillakin runsaasti. Ne mahdollistuvat erilaisissa kirkon kokouksissa ja konferensseissa sekä opiskelupaikkakunnalla Kreikassa.

The church must become the people of Soweto : Manas Buthelezi’s existential-Christocentric understanding of the church

The aim of this study has been to discern what Manas Buthelezi (1935-), a black South African Lutheran theologian and later also a bishop, regards as the requirements a church has to fulfill in order to be credible in the apartheid society. Buthelezi’s dissertation and several articles written between the years 1968 and 1993 are the sources of this study. Also the lectures held in Heidelberg in 1972 are referred to. Systematic analysis is the method used. The question of the credibility of the church is studied through three concepts that play an important role in Buthelezi’s ecclesiological thought, namely the wholeness of life, incarnation and liberation. The notion of the wholeness of life stems from the African tradition. Buthelezi takes the concept into the Christian church: the church should realize that God is the Creator of all life and Christ the lord of every aspect of human existence. Life is one entity coram Deo. However, the church is not to become the world; solidarity between the two must remain critical as the church is also called to play a prophetic role in the society. The church is in an open relationship with the world. It has a unique message of forgiveness and reconciliation. Nevertheless, the message is not a possession of the church but it is addressed to the whole world. The meaning of incarnation comes close to that of the wholeness of life. Following the example of Christ’s incarnation, the church must become human in the reality of the people. The church in Soweto is to become the people of Soweto, that is, the church must become as vulnerable as the people are. An incarnate church cannot be immune to the oppression that people experience, because the people are the church. The church is therefore bound to suffer. Buthelezi’s theology of the cross is pragmatic: the suffering of the church aims at the liberation of the oppressed. At times the physical presence of the church by the side of the suffering people is the only way to preach the incarnate gospel. In the South Africa of the late 1960s onwards the liberation of the oppressed black people was high on the agenda of Black Theology. As a leader of the early South African Black Theology, Buthelezi is concerned about the racial injustice in his country. He urges the churches to join the struggle against it as one people of God. The notions of liberation and the wholeness of life emerge in Buthelezi’s holistic understanding of liberation that involves the inner liberation of the black spirit and the liberation of the economic, social and political aspects of life. Interpreting Tillich’s correlation method in the South African situation, and also paralleling other liberation theologians, Buthelezi takes the existential situation of the people as the starting point for liberation. The gospel has to respond to the existential questions of people. The church is called to work for the liberation of society but it must also be liberated itself. Buthelezi initiated the LWF statement on the status confessionis in South Africa (1977). In line with the statement, he calls for church unity on the human level. For the unity to be true, it has to be experienced on the grassroots’ level. All the three concepts covered urge the church to come down from any ivory tower and out of any spiritual haven it might hide in. A lot of the credibility of the church derives from the behavior of the people. Buthelezi’s concentration on how the people who constitute the church should live their faith leaves less attention to how God constitutes the church. I have labeled Buthelezi’s understanding of the church existential-Christocentric due to the emphasis he lays on the need of the church to take the existential situation of the people seriously and on the other hand, on Christ as the exemplar for the church.

Essays on Banking Crises

This thesis aims at finding the role of deposit insurance scheme and central bank (CB) in keeping the banking system safe. The thesis also studies the factors associated with long-lasting banking crises. The first essay analyzes the effect of using explicit deposit insurance scheme (EDIS), instead of using implicit deposit insurance scheme (IDIS), on banking crises. The panel data for the period of 1980-2003 includes all countries for which the data on EDIS or IDIS exist. 70% of the countries in the sample are less developed countries (LDCs). About 55% of the countries adopting EDIS also come from LDCs. The major finding is that the using of EDIS increases the crisis probability at a strong significance level. This probability is greater if the EDIS is inefficiently designed allowing higher scope of moral hazard problem. Specifically, the probability is greater if the EDIS provides higher coverage to deposits and if it is less powerful from the legal point of view. This study also finds that the less developed a country is to handle EDIS, the higher the chance of banking crisis. Once the underdevelopment of an economy handling the EDIS is controlled, the EDIS separately is no longer a significant factor of banking crises. The second essay aims at determining whether a country s powerful CB can lessen the instability of the banking sector by minimizing the likelihood of a banking crisis. The data used include indicators of the CB s autonomy for a set of countries over the period of 1980-89. The study finds that in aggregate a more powerful CB lessens the probability of banking crisis. When the CB s authority is disentangled with respect to its responsibilities, the study finds that the longer tenure of CB s chief executive officer and the greater power of CB in assigning interest rate on government loans are necessary for reducing the probability of banking crisis. The study also finds that the probability of crisis reduces more if an autonomous CB can perform its duties in a country with stronger law and order tradition. The costs of long-lasting banking crises are high because both the depositors and the investors lose confidence in the banking system. For a rapid recovery of a crisis, the government very often undertakes one or more crisis resolution policy (CRP) measures. The third essay examines the CRP and other explanatory variables correlated with the durations of banking crises. The major finding is that the CRP measure allowing the regulation forbearance to keep the insolvent banks operative and the public debt relief program are respectively strongly and weakly significant to increase the durations of crises. Some other explanatory variables, which were found by previous studies to be related with the probability of crises to occur, are also correlated with the durations of crises.

Towards web-based semantic enrichment of 3D insects

Natural history collections are an invaluable resource housing a wealth of knowledge with a long tradition of contributing to a wide range of fields such as taxonomy, quarantine, conservation and climate change. It is recognized however [Smith and Blagoderov 2012] that such physical collections are often heavily underutilized as a result of the practical issues of accessibility. The digitization of these collections is a step towards removing these access issues, but other hurdles must be addressed before we truly unlock the potential of this knowledge.

Reinventing Nordic Openness : Transparency and State Information in Finland

The study explores new ideational changes in the information strategy of the Finnish state between 1998 and 2007, after a juncture in Finnish governing in the early 1990s. The study scrutinizes the economic reframing of institutional openness in Finland that comes with significant and often unintended institutional consequences of transparency. Most notably, the constitutional principle of publicity (julkisuusperiaate), a Nordic institutional peculiarity allowing public access to state information, is now becoming an instrument of economic performance and accountability through results. Finland has a long institutional history in the publicity of government information, acknowledged by law since 1951. Nevertheless, access to government information became a policy concern in the mid-1990s, involving a historical narrative of openness as a Nordic tradition of Finnish governing Nordic openness (pohjoismainen avoimuus). International interest in transparency of governance has also marked an opening for institutional re-descriptions in Nordic context. The essential added value, or contradictory term, that transparency has on the Finnish conceptualisation of governing is the innovation that public acts of governing can be economically efficient. This is most apparent in the new attempts at providing standardised information on government and expressing it in numbers. In Finland, the publicity of government information has been a concept of democratic connotations, but new internationally diffusing ideas of performance and national economic competitiveness are discussed under the notion of transparency and its peer concepts openness and public (sector) information, which are also newcomers to Finnish vocabulary of governing. The above concepts often conflict with one another, paving the way to unintended consequences for the reforms conducted in their name. Moreover, the study argues that the policy concerns over openness and public sector information are linked to the new drive for transparency. Drawing on theories of new institutionalism, political economy, and conceptual history, the study argues for a reinvention of Nordic openness in two senses. First, in referring to institutional history, the policy discourse of Nordic openness discovers an administrative tradition in response to new dilemmas of public governance. Moreover, this normatively appealing discourse also legitimizes the new ideational changes. Second, a former mechanism of democratic accountability is being reframed with market and performance ideas, mostly originating from the sphere of transnational governance and governance indices. Mobilizing different research techniques and data (public documents of the Finnish government and international organizations, some 30 interviews of Finnish civil servants, and statistical time series), the study asks how the above ideational changes have been possible, pointing to the importance of nationalistically appealing historical narratives and normative concepts of governing. Concerning institutional developments, the study analyses the ideational changes in central steering mechanisms (political, normative and financial steering) and the introduction of budget transparency and performance management in two cases: census data (Population Register Centre) and foreign political information (Ministry for Foreign Affairs). The new policy domain of governance indices is also explored as a type of transparency. The study further asks what institutional transformations are to be observed in the above cases and in the accountability system. The study concludes that while the information rights of citizens have been reinforced and recalibrated during the period under scrutiny, there has also been a conversion of institutional practices towards economic performance. As the discourse of Nordic openness has been rather unquestioned, the new internationally circulating ideas of transparency and the knowledge economy have entered this discourse without public notice. Since the mid 1990s, state registry data has been perceived as an exploitable economic resource in Finland and in the EU public sector information. This is a parallel development to the new drive for budget transparency in organisations as vital to the state as the Population Register Centre, which has led to marketization of census data in Finland, an international exceptionality. In the Finnish Ministry for Foreign Affairs, the post-Cold War rhetorical shift from secrecy to performance-driven openness marked a conversion in institutional practices that now see information services with high regards. But this has not necessarily led to the increased publicity of foreign political information. In this context, openness is also defined as sharing information with select actors, as a trust based non-public activity, deemed necessary amid the global economic competition. Regarding accountability system, deliberation and performance now overlap, making it increasingly difficult to identify to whom and for what the public administration is accountable. These evolving institutional practices are characterised by unintended consequences and paradoxes. History is a paradoxical component in the above institutional change, as long-term institutional developments now justify short-term reforms.

Ethics and Aesthetics : Intersections in Iris Murdoch's Philosophy

The study addresses the question concerning the relationship between ethics and aesthetics in the philosophy of Iris Murdoch. The main argument is that Murdoch s philosophy cannot be accurately understood without an understanding of the relationship she sees between the aesthetic experience and morality. Reading Murdoch s philosophy with this relationship in mind shows that it must be considered as a relevant alternative to the main forms of aesthetic-ethical theories. The study consists of seven previously published articles and a summary. It shows that Murdoch belongs to a tradition of philosophers who seek to broaden the scope of ethics by reference to aesthetic value and aesthetic experience. She sees an attitude responsible for aesthetic experiences as relevant for morality. However, she does not collapse morality into aesthetic experience. The two meet on the level of the subject s attitude towards its object, but there is a distinction between the experiences that accompany the attitudes. Aesthetic experiences can function as a clue to morals in that they present in a pleasing manner moral truths which otherwise might be psychologically too difficult to face. Murdoch equates the aesthetic attitude with virtuous love characterized by unselfish attention to its object. The primary object of such love is in Murdoch s account another human individual in her particularity. She compares the recognition of the other person as a particular existence to the experience of the Kantian sublime and offers her own version of the true sublime which is the experience of awe in the face of the infinity of the task of understanding others. One of the most central claims in Murdoch s philosophy is that human consciousness is evaluatively structured. This claim challenges the distinction between facts and values which has had an immense influence on modern moral philosophy. One argument with which Murdoch supports her claim is the nature of great literature. According to her, the standard of greatness in literature is the authors awareness of the independent existence of individuals in the particularity of their evaluative consciousnesses. The analysis of the standard of greatness in literature is also Murdoch s only argument for the claim that the primary object of the loving unselfish attention is the other particular individual. She is convinced that great literature reveals a deep truth about the human condition with its capacity to capture the particular. Abstract philo¬sophical discourse cannot compete with this capacity but it should take truths revealed by literature seriously in its theorising. Recognising this as Murdoch s stand on the question of the relation between philosophy and literature as forms of human discourse settles whether she is part of what has been called philosophy s turn to literature. The answer is yes.

Essays in Philosophical Moral Psychology

The dissertation consists of four essays and a comprehensive introduction that discusses the topics, methods, and most prominent theories of philosophical moral psychology. I distinguish three main questions: What are the essential features of moral thinking? What are the psychological conditions of moral responsibility? And finally, what are the consequences of empirical facts about human nature to normative ethics? Each of the three last articles focuses on one of these issues. The first essay and part of the introduction are dedicated to methodological questions, in particular the relationship between empirical (social) psychology and philosophy. I reject recent attempts to understand the nature of morality on the basis of empirical research. One characteristic feature of moral thinking is its practical clout: if we regard an action as morally wrong, we either refrain from doing it even against our desires and interests, or else feel shame or guilt. Moral views seem to have a conceptual connection to motivation and emotions – roughly speaking, we can’t conceive of someone genuinely disapproving an action, but nonetheless doing it without any inner motivational conflict or regret. This conceptual thesis in moral psychology is called (judgment) internalism. It implies, among other things, that psychopaths cannot make moral judgments to the extent that they are incapable of corresponding motivation and emotion, even if they might say largely the words we would expect. Is internalism true? Recently, there has been an explosion of interest in so-called experimental philosophy, which is a methodological view according to which claims about conceptual truths that appeal to our intuitions should be tested by way of surveys presented to ordinary language users. One experimental result is that the majority of people are willing to grant that psychopaths make moral judgments, which challenges internalism. In the first article, ‘The Rise and Fall of Experimental Philosophy’, I argue that these results pose no real threat to internalism, since experimental philosophy is based on a too simple conception of the relationship between language use and concepts. Only the reactions of competent users in pragmatically neutral and otherwise conducive circumstances yield evidence about conceptual truths, and such robust intuitions remain inaccessible to surveys for reasons of principle. The epistemology of folk concepts must still be based on Socratic dialogue and critical reflection, whose character and authority I discuss at the end of the paper. The internal connection between moral judgment and motivation led many metaethicists in the past century to believe along Humean lines that judgment itself consists in a pro-attitude rather than a belief. This expressivist view, as it is called these days, has far-reaching consequences in metaethics. In the second essay I argue that perhaps the most sophisticated form of contemporary expressivism, Allan Gibbard’s norm-expressivism, according to which moral judgments are decisions or contingency plans, is implausible from the perspective of the theory of action. In certain circumstances it is possible to think that something is morally required of one without deciding to do so. Morality is not a matter of the will. Instead, I sketch on the basis of Robert Brandom’s inferentialist semantics a weak form of judgment internalism, according to which the content of moral judgment is determined by a commitment to a particular kind of practical reasoning. The last two essays in the dissertation emphasize the role of mutual recognition in the development and maintenance of responsible and autonomous moral agency. I defend a compatibilist view of autonomy, according to which agents who are unable to recognize right and wrong or act accordingly are not responsible for their actions – it is not fair to praise or blame them, since they lacked the relevant capacity to do otherwise. Conversely, autonomy demands an ability to recognize reasons and act on them. But as a long tradition in German moral philosophy whose best-known contemporary representative is Axel Honneth has it, both being aware of reasons and acting on them requires also the right sort of higher-order attitudes toward the self. Without self-respect and self-confidence we remain at the mercy of external pressures, even if we have the necessary normative competence. These attitudes toward the self, in turn, are formed through mutual recognition – we value ourselves when those who we value value us. Thus, standing in the right sort of relations of recognition is indirectly necessary for autonomy and moral responsibility. Recognition and valuing are concretely manifest in actions and institutions, whose practices make possible participation on an equal footing. Seeing this opens the way for a kind of normative social criticism that is grounded in the value of freedom and automomy, but is not limited to defending negative rights. It thus offers a new way to bridge the gap between liberalism and communitarianism.

Yhteisöllisyys juutalaisessa kansallisuusajattelussa ja Israelin valtion itsenäisyysjulistuksessa

The Idea of Community in the Jewish National Thinking and in the Proclamation of Independence The aim of this study is to clarify the idea of community in the Jewish national thinking and in the Proclamation of Independence of the State of Israel in 1948. The method is the community analysis. The values of the culture are studied by two- and threefold dimensions on the arena. On the field of that arena one can find the society of order, the society of pressure, the societies made by mosaics and the societies that are breaking apart. The community way of behaving means, that the individuals voluntarily follow common values. The earliest Jewish ideals elevated the concept of unity among the people. The reality in the society was different especially in Roman times when the religious and national thinking was fragmented into four different main views. During the Diaspora the religious tradition mostly warned against pursuing a Jewish state, but many forms of Anti-Judaism and the new national thinking in the nineteenth century created the Zionist movement. The religious Jewish people did not rely on the earthy nationalism and when some of them later chose Zionism, they stressed the religious aspects in governing the state. The cultural Zionists preferred a slower and more low key spiritual way of change. The Revisionists saw no alternatives but to use military force. Many in the majority, the Labour movement, hoped that the progress brought to the region by Zionism would change the minds of opponents. The general appearance of the proclamation is optimistic. It characterizes national and political unity gathering people who think differently and who come from different factions of the Jewish political and cultural orientation. These people can be placed on different corners in the community analysis. The proclamation concentrates on state and administrative points of view. It aims at a state for the Jews, and the Jewishness of the state is more clearly seen in later legislation. The hope for co-operation from all sides was clearly articulated. The central aim was the security of the Jews. The proclamation has a community quotation because it aimed to build up a net of cooperation. The vision of building a nation of their own is balanced by the collaboration with the Arabs and the international community. In the same roclamation the individual civil rights are side by side with the Prophets thoughts about peace and justice. The Proclamation describes a society of a good order which aims at uniting the people. In the midst of grave difficulties a noble proclamation of national and international co-operation was created. It was not taken for granted that the ideals would be realized. The care of the national homeland could become egocentric nationalism and the attention to the Prophets heritage could turn to emphasizing strict religious rules or to isolation from others. The emphasis of civil rights could turn to assimilation or in other words to other kinds of values in their own country.

A systematic-ecological approach to Baltic Sea ice studies of algae and protists

The seasonal occurrence of sea ice that annually covers almost half the Baltic Sea area provides a unique habitat for halo- and cold temperature-tolerant extremophiles. Baltic Sea ice biology has more than 100 years of tradition that began with the floristic observation of species by the early pioneers using light microscopic techniques that were the only thing available at the time. Since the discovery of life within sea ice, more technologies have become available for taxonomy. Electron microscopy and genetic evidence have been used to identify sea ice biota revealing increased numbers of taxa. Meanwhile ecologists have used light microscopic cell enumeration in addition to the chemical and physical properties of sea ice in attempts to explain the food web structure of sea ice and its functions. Thus, during the Baltic winter, the sea ice hosts more abundant and diverse microbial communities than the water column beneath it. These communities are typically dominated by autotrophic diatoms together with a diverse assortment of dinoflagellates, auto- and heterotrophic flagellates, ciliates, metazoan rotifers and bacteria, which are mostly responsible for the recycling of nutrients. This thesis comprises ecological and systematic studies. In addition to the results of the previous studies carried out on landfast ice, the data presented here provide new insight into the spatial distribution of pelagial sea ice, which has remained largely unexplored. The studies reveal spatial heterogeneity in the pelagial sea ice of the Gulf of Bothnia. There were mismatches in chlorophyll-a concentrations and in photosynthetic efficiencies of the communities studied. The temporal succession was followed and experimental studies performed investigating the community responses towards increased or decreased light in landfast ice in the Gulf of Finland. The systematic studies carried out with established dinoflagellate cultures revealed a new resting cyst belonging to common sea ice dinoflagellate, Scrippsiella hangoei (Schiller) Larsen 1995. The cyst can be used to explain the overwintering of this species during prolonged periods of darkness. The dissimilarities and similarities in the material isolated from the sea ice called for description of a new subspecies Heterocapsa arctica ssp. frigida. The cells obtained in the cultured material were unlike those of the previously described species, necessitating description of ssp. frigida. As a result of its own unique habitus, the subspecies had been noted by Finnish taxonomists during the past three decades and thus its annual occurrence and geographical distribution in the Baltic Sea. This illustrates how combining ecology and systematics increases our understanding of organisms.

Engineering the pentose phosphate pathway of Saccharomyces cerevisiae for production of ethanol and xylitol

The baker s yeast Saccharomyces cerevisiae has a long tradition in alcohol production from D-glucose of e.g. starch. However, without genetic modifications it is unable to utilise the 5-carbon sugars D-xylose and L arabinose present in plant biomass. In this study, one key metabolic step of the catabolic D-xylose pathway in recombinant D-xylose-utilising S. cerevisiae strains was studied. This step, carried out by xylulokinase (XK), was shown to be rate-limiting, because overexpression of the xylulokinase-encoding gene XKS1 increased both the specific ethanol production rate and the yield from D xylose. In addition, less of the unwanted side product xylitol was produced. Recombinant D-xylose-utilizing S. cerevisiae strains have been constructed by expressing the genes coding for the first two enzymes of the pathway, D-xylose reductase (XR) and xylitol dehydrogenase (XDH) from the D-xylose-utilising yeast Pichia stipitis. In this study, the ability of endogenous genes of S. cerevisiae to enable D-xylose utilisation was evaluated. Overexpression of the GRE3 gene coding for an unspecific aldose reductase and the ScXYL2 gene coding for a xylitol dehydrogenase homologue enabled growth on D-xylose in aerobic conditions. However, the strain with GRE3 and ScXYL2 had a lower growth rate and accumulated more xylitol compared to the strain with the corresponding enzymes from P. stipitis. Use of the strictly NADPH-dependent Gre3p instead of the P. stipitis XR able to utilise both NADH and NADPH leads to a more severe redox imbalance. In a S. cerevisiae strain not engineered for D-xylose utilisation the presence of D-xylose increased xylitol dehydrogenase activity and the expression of the genes SOR1 or SOR2 coding for sorbitol dehydrogenase. Thus, D-xylose utilisation by S. cerevisiae with activities encoded by ScXYL2 or possibly SOR1 or SOR2, and GRE3 is feasible, but requires efficient redox balance engineering. Compared to D-xylose, D-glucose is a cheap and readily available substrate and thus an attractive alternative for xylitol manufacture. In this study, the pentose phosphate pathway (PPP) of S. cerevisiae was engineered for production of xylitol from D-glucose. Xylitol was formed from D-xylulose 5-phosphate in strains lacking transketolase activity and expressing the gene coding for XDH from P. stipitis. In addition to xylitol, ribitol, D-ribose and D-ribulose were also formed. Deletion of the xylulokinase-encoding gene increased xylitol production, whereas the expression of DOG1 coding for sugar phosphate phosphatase increased ribitol, D-ribose and D-ribulose production. Strains lacking phosphoglucose isomerase (Pgi1p) activity were shown to produce 5 carbon compounds through PPP when DOG1 was overexpressed. Expression of genes encoding glyceraldehyde 3-phosphate dehydrogenase of Bacillus subtilis, GapB, or NAD-dependent glutamate dehydrogenase Gdh2p of S. cerevisiae, altered the cellular redox balance and enhanced growth of pgi1 strains on D glucose, but co-expression with DOG1 reduced growth on higher D-glucose concentrations. Strains lacking both transketolase and phosphoglucose isomerase activities tolerated only low D-glucose concentrations, but the yield of 5-carbon sugars and sugar alcohols on D-glucose was about 50% (w/w).

A playful side to twelfth-century mathematics

As editors of the book Lilavati's Daughters: The Women Scientists of India, reviewed by Asha Gopinathan (Nature 460, 1082; 2009), we would like to elaborate on the background to its title. Lilavati was a mathematical treatise of the twelfth century, composed by the mathematician and astronomer Bhaskaracharya (1114–85) — also known as Bhaskara II — who was a teacher of repute and author of several other texts. The name Lilavati, which literally means 'playful', is a surprising title for an early scientific book. Some of the mathematical problems posed in the book are in verse form, and are addressed to a girl, the eponymous Lilavati. However, there is little real evidence concerning Lilavati's historicity. Tradition holds that she was Bhaskaracharya's daughter and that he wrote the treatise to console her after an accident that left her unable to marry. But this could be a later interpolation, as the idea was first mentioned in a Persian commentary. An alternative view has it that Lilavati was married at an inauspicious time and was widowed shortly afterwards. Other sources have implied that Lilavati was Bhaskaracharya's wife, or even one of his students — raising the possibility that women in parts of the Indian subcontinent could have participated in higher education as early as eight centuries ago. However, given that Bhaskara was a poet and pedagogue, it is also possible that he chose to address his mathematical problems to a doe-eyed girl simply as a whimsical and charming literary device.

Bi-cultural content publication on a digital noticeboard: A design and cultural differences case study

We present our observations of Aboriginal Australian practices around a custom digital noticeboard and compare our insights to related research on cultural differences, literacy and ICT4D. The digital noticeboard was created, upon a request by the community Elders, to foster communication across the community. The initial design, informed by discussions and consultations, aimed at supporting the local Aboriginal language and English, both in written and spoken form, at supporting the oral tradition, and at accommodating for different perceptions and representations of time. This paper presents observations about the first encounters with the digital noticeboard by those members of the community that took part in its conceptualization. Such observations reinforce existing knowledge on such cultural phenomena as collectivism and time perception, issues related to literacy, moderation and censorship. We contribute to framing such knowledge within a concrete case study and draw implication for design of tools for bi-cultural content publication.

Fragmented utopias

This chapter examines radical propositions that the ultimate reality was a constantly shifting and euphoric flux of fragmentary forces. In the history of ideas these models of reality were proposed by counter-cultural and poststructuralist theorists who wanted to liberate consciousness from an instrumental social reality. For thinkers such as R.D. Laing, Timothy Leary and Deleuze and Guattari conditions such as schizophrenia and the unconscious, and the role of desire and hallucinogenic drugs provided insight into an expanded psyche and access to the ultimate reality. Emerging from a tradition of intellectual dissent, and driven by an idealistic desire to cure the world's ills, these writers placed their faith in misological and ecstatic utopias.

Diverse bodies-space politics: Towards a critique of social (in)justice of built environment

Writing has long played an important role in the progression of architecture and the built environment. Histories of architecture are written, manifestoes that form the basis for a designer’s work are written and most importantly, the built environment advances itself through the act of critical writing. Not unlike the visual arts, literature and poetry, the tradition of written criticism has been crucial to the progression of architecture and its allied professions (Franz 2003). This article contributes to architecture and the built environment through the act of a written essay that critiques the problem of bodily diversity to architecture. In particular, the article explores the implications of body-space politics and abstracted body thinking on diverse bodies and their spatial justice. Using Soja’s Spatial Justice theory (2008), we seek to point out the underlying conceptions and power differentials assigned to different bodies spatially and how this leads to spatial injustices and contested spaces. The article also critically analyses the historical emergence of ‘the standardised body’ in architecture and its application in design theory and practice , and looks at how bodies often found on the outside of architecture highlight how such thinking creates in justices. Different theories are drawn on to help point to how design through the use of the upright, forward facing, male bod willingly and unwillingly denies access to resources and spatialities of everyday life. We also suggest ways to re-conceptualise the body in design practice and teaching.
