Voiko sota olla oikeutettu? : Kirkkojen maailmanneuvoston yleiskokousten kannanotot sotaan kriisien ratkaisuna

Can war be justified? Expressions of opinions by the general assemblies of the World Council of Churches on the question of war as a method of settling conflicts. The purpose of this study is to describe and analyse the expressions of opinions recorded in the documents of the general assemblies of the WCC during the Cold War period from 1948 to 1983 on the use of war as a method of settling international and national conflicts. The main sources are the official reports of the WCC´s assemblies during the years 1948 to 1983. This study divides the discussions into three periods. The first period (1949-1968) is dominated by the pressures arising from the Second World War. Experiences of the war led the assemblies of the WCC to the conclusion that modern warfare as a method of settling conflicts should be rejected. Modern war was contrary to God´s purposes and the whole meaning of creation, said the assembly. Although the WCC rejected modern war, it left open the possibility of conflict where principles of just war may be practised. The question of war was also linked to the state and its function, which led to the need to create a politically neutral doctrine for the socio-ethical thinking of churches and of the WCC itself. The doctrine was formulated using the words "responsible society". The question of war and socio-ethical thinking were on the WCC`s agenda throughout the first period. Another issue that had an influence on the first period was the increasing role of Third World countries. This new dimension also brought new aspects to the question of war and violence. The second period (1968-1975) presented greater challenges to the WCC, especially in traditional western countries. The Third World, political activity in the socialist world and ideas of revolution were discussed. The WCC`s fourth Assembly in Uppsala was challenged by these new ideas of revolution. The old doctrine of "responsible society" was seen by many participants as unsuitable in the modern world, especially for Third World countries. The situation of a world governed by armaments, causing social and economic disruption, was felt by churches to be problematic. The peace movement gathered pace and attention. There was pressure to see armed forces as an option on the way to a new world order. The idea of a just war was challenged by that of just revolution. These ideas of revolution did not receive support from the Uppsala Assembly, but they pressured the WCC to reconsider its socio-ethical thinking. Revolution was seen as a possibility, but only when it could be peaceful. In the Nairobi Assembly the theme of just, participatory and sustainable society provided yet another viewpoint, dealing with the life of the world and its problems as a whole. The third period (1975-1983) introduced a new, alternative doctrine the "JPIC Process", justice, peace and the integrity of creation for social thinking in the WCC. The WCC no longer wanted to discuss war or poverty as separate questions, but wanted to combine all aspects of life to see the impact of an arms-governed world on humankind. Thus, during the last period, discussions focused on socio-ethical questions, where war and violence were only parts of a larger problem. Through the new JPIC Process, the WCC`s Assembly in Vancouver looked for a new world, one without violence, in all aspects of life. Despite differing opinions in socio-ethical thinking, the churches in the WCC agreed that modern warfare cannot be regarded as acceptable or just. The old idea of a "just war" still had a place, but it was not seen by all as a valid principle. As a result the WCC viewed war as a final solution to be employed when all other methods had failed. Such a war would have to secure peace and justice for all. In the discussions there was a strong political east-west divide, and, during the last two decades, a north-south divide as well. The effect of the Cold War was obvious. In the background to the theological positions were two main concepts namely the idea of God´s activity in man´s history through the so-called regiments and, the concept of the Kingdom of God on Earth.

The Edge of Danger: artificial lighting and the dialectics of domestic occupation in Philip Johnson's Glass and Guest Houses

In the first half of the twentieth century the dematerializing of boundaries between enclosure and exposure problematized traditional acts of “occupation” and understandings of the domestic environment. As a space of escalating technological control, the modern domestic interior offered new potential to re-define the meaning and means of habitation. This shift is clearly expressed in the transformation of electric lighting technology and applications for the modern interior in the mid-twentieth century. Addressing these issues, this paper examines the critical role of electric lighting in regulating and framing both the public and private occupation of Philip Johnson’s New Canaan estate. Exploring the dialectically paired transparent Glass House and opaque Guest House (both 1949), this study illustrates how Johnson employed artificial light to control the visual environment of the estate as well as to aestheticize the performance of domestic space. Looking closely at the use of artificial light to create emotive effects as well as to intensify the experience of occupation, this revisiting of the iconic Glass House and lesser-known Guest House provides a more complex understanding of Johnson’s work and the means with which he inhabited his own architecture. Calling attention to the importance of Johnson serving as both architect and client, and his particular interest in exploring the new potential of architectural lighting in this period, this paper investigates Johnson’s use of electric light to support architectural narratives, maintain visual order and control, and to suit the nuanced desires of domestic occupation.

Field performance of in-service cast iron gas reticulation pipe buried in reactive clay

Field instrumentation of an in-service cast iron gas pipe buried in a residential area is detailed in this paper. The aim of the study was to monitor the long-term pipe behavior to understand the mechanisms of pipe bending in relation to ground movement as a result of seasonal fluctuation of soil moisture content. Field data showed that variation of soil temperature, suction, and moisture content are closely related to the prevailing climate. Change of soil temperature is generally related to the ambient air temperature, with a variation of approximately −3°C −3°C per meter depth from the ground surface in summer (decrease with depth) and winter (increase with depth). Seasonal cyclic variation in moisture content was observed with maxima in February and March, and a minimum around September. The pipe top was under tensile strain during summer and subsequently subjected to compressive strain as soil swelling occurred as a result of increase in moisture content. The study suggests that downward pipe bending occurs in summer because of soil shrinkage, while upward pipe bending occurs in winter when the soil swells.

The Role of Interface Modification on Thermal Degradation and Crystallization Behavior of Composites from Commingled Polypropylene Fiber and Banana Fiber

The thermal degradation behavior of banana fiber and polypropylene/banana fiber composites has been studied by thermogravimetric analysis. Banana fiber was found to be decomposing in two stages, first one around 320 degrees C and the second one around 450 degrees C. For chemically treated banana fiber, the decomposition process has been at a higher temperature, indicating thermal stability for the treated fiber. Activation energies for thermal degradation were estimated using Coats and Redfern method. Calorific value of the banana fiber was measured using a constant volume isothermal bomb calorimeter. rystallization studies exhibited an increase in the crystallization temperature and crystallinity of polypropylene upon the addition of banana fiber.

On compressible boundary layer on a flat plate with uniform suction

A quartic profile in terms of the normal distance from the wall has been taken and coefficients are evaluated by satisfying one more boundary condition on the wall than the usual one. By doing so, the limitations about the Reynolds number of the quartic profile adopted by Lew (1949) has been removed. The Kármán (1921) Momentum Integral Equation has been used to evaluate the various characteristics of the flow. A comparative study of Lew's quartic profile and exponential profile together with the quartic profile of the present paper has been undertaken and the graphs for the various characteristics of the flow for a number of Mach numbers and suction coefficients have been drawn. At the end, certain conclusions of general nature about the velocity profiles have been recorded.

The Shannon Cipher System with a Guessing Wiretapper: General Sources

The Shannon cipher system is studied in the context of general sources using a notion of computational secrecy introduced by Merhav & Arikan. Bounds are derived on limiting exponents of guessing moments for general sources. The bounds are shown to be tight for iid, Markov, and unifilar sources, thus recovering some known results. A close relationship between error exponents and correct decoding exponents formfixed rate source compression on the one hand and exponents for guessing moments on the other hand is established.

Coupled ocean-atmosphere inter-decadal modes in the tropics

Homogencous upper air data for 50 years (1949-1998) from the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis project, sea surface temperatures and sea level pressure are used to bring out the three dimensional structure of two dominant decadal/multi-decadal variations in the tropics. The global three dimensional modes represent generalized forms of inter-decadal modes studied earlier only with surface data. In the vertical, both modes show approximate first baroclinic structures over the tropics. The Walker circulation associated with the multidecadal mode has a wavenumber two structure in the zonal direction. It is shown that the magnitude of major ascending and descending motions associated with the multi-decadal Hadley and Walker circulations, are comparable to those associated with the dominant inter-annual mode. Implications of these large scale global circulations associated with the low frequency oscillations in modulating regional climate on a inter-annual time scale are discussed.

Density-wave theory of dislocations in crystals

The density-wave theory of Ramakrishnan and Yussouff is extended to provide a scheme for describing dislocations and other topological defects in crystals. Quantitative calculations are presented for the order-parameter profiles, the atomic configuration, and the free energy of a screw dislocation with Burgers vector b=(a/2, a/2, a/2) in a bcc solid. These calculations are done using a simple parametrization of the direct correlation function and a gradient expansion. It is conventional to express the free energy of the dislocation in a crystal of size R as (λb2/4π)ln(αR/‖b‖), where λ is the shear elastic constant, and α is a measure of the core energy. Our results yield for Na the value α≃1.94a/(‖c1’’‖)1/2 (≃1.85) at the freezing temperature (371 K) and α≃2.48a/(‖c1’’‖)1/2 at 271 K, where c1’’ is the curvature of the first peak of the direct correlation function c(q). Detailed results for the density distribution in the dislocation, particularly the core region, are also presented. These show that the dislocation core has a columnar character. To our knowledge, this study represents the first calculation of dislocation structure, including the core, within the framework of an order-parameter theory and incorporating thermal effects.

Väinö Kantele lähetystyöntekijänä kommunistien valtaannousun aikana Kiinassa 1948—1951

Tämä tutkimus tarkastelee pastori Väinö Kanteleen työtä lähetystyöntekijänä Kiinassa hänen kolmannella työkaudellaan 1948 - 1951. Tutkimuksen keskeisimmät lähteet ovat Kanteleen perheelleen osoittamat päiväkirjamaiset kirjeet sekä Suomen Lähetysseuran (SLS) johtokunnan kokousten ja lähettien kokousten pöytäkirjat. Tutkimus on mikrohistoriallinen sivuten henkilö- ja lähetyshistoriaa. Kantele saapui Yungšunin asemalle maaliskuussa 1948. Asemalle oli kaivattu kokenutta mieslähettiä. Työkauden alku sujui hyvin Kiinan poliittisen tilanteen levottomuudesta huolimatta. Tilanne kuitenkin kiristyi kommunistien saadessa lisää kannatusta. SLS kutsui lähetit pois työalueelta keväällä 1949. Kantele päätti jäädä Kiinaan. Yungšunin seurakunta oli toivonut hänen jäämistään. Lisäksi mahdollisuudet lähetystyön tekemiseen olivat yhä olemassa huolimatta Kiinan kansantasavallan perustamisesta lokakuussa 1949. Olosuhteet alkoivat kuitenkin asteittain kiristyä. Hajanaisten sotilasjoukkojen sekä kommunistiarmeijan liikkuminen ympäri Kiinaa häiritsivät lähetystyötä. Sotilaat muun muassa valtasivat lähetysasemia käyttöönsä. Ongelmana olivat myös inflaatio ja postin kulun epävarmuus. Henkilökohtaisesti Kanteletta vaivasi myös tunne oman uskonsa heikkoudesta. Vuonna 1950 Kiinan poliittiset uudistukset rajoittivat lähetystyötä entisestään. Heinäkuussa julkaistu Kirkkojen manifesti vaati kirkkojen pikaista irrottautumista ulkomaisista yhteyksistään, käytännössä lähetysjärjestöistä. Samana vuonna aloitettiin maareformi. Seurakuntiin asetettiin kokoontumiskielto reformin toteuttamisen ajaksi. Yungšunissa kieltoa ei kumottu enää Kanteleen työkauden aikana. Uudistusten myötä Kanteleen liikkumisvapautta rajoitettiin. Viranomaiset hakivat hänet välillä moneksi päiväksi kuulusteluihin. Lopulta hän eli käytännössä vankina asemallaan. Tammikuussa 1951 hän koki, ettei lähetystyön tekemiseen ole mahdollisuuksia, ja anoi maastapoistumislupaa viranomaisilta. Alkoi pitkä ja epävarma odotus. Kantele alkoi laulaa kiinankielisiä virsiä kovaan ääneen asemalla koska koki, että se oli ainoa jäljellä oleva keino levittää kristinuskon sanomaa. Tapansa vuoksi hänet tunnettiin laulavana evankelistana. Tie kotiin avautui lopulta heinäkuussa 1951. Kantele koki työnsä lähetyssaarnaajana tärkeäksi ja rakkaaksi. Hän oli valmis työskentelemään hankalissa olosuhteissa. Hän oli hyvin ihmisläheinen ja kuvaili kirjeissään paljon tapaamiaan ihmisiä. Kantele oli käytännön ihminen eikä hänen kirjoituksissaan ole havaittavissa taipumusta opillisiin pohdintoihin.

Proofs, Paradoxes, and Probabilities : The Logical Turn of Philosophy in Finland

This monograph describes the emergence of independent research on logic in Finland. The emphasis is placed on three well-known students of Eino Kaila: Georg Henrik von Wright (1916-2003), Erik Stenius (1911-1990), and Oiva Ketonen (1913-2000), and their research between the early 1930s and the early 1950s. The early academic work of these scholars laid the foundations for today's strong tradition in logic in Finland and also became internationally recognized. However, due attention has not been given to these works later, nor have they been comprehensively presented together. Each chapter of the book focuses on the life and work of one of Kaila's aforementioned students, with a fourth chapter discussing works on logic by authors who would later become known within other disciplines. Through an extensive use of correspondence and other archived material, some insight has been gained into the persons behind the academic personae. Unique and unpublished biographical material has been available for this task. The chapter on Oiva Ketonen focuses primarily on his work on what is today known as proof theory, especially on his proof theoretical system with invertible rules that permits a terminating root-first proof search. The independency of the parallel postulate is proved as an example of the strength of root-first proof search. Ketonen was to our knowledge Gerhard Gentzen's (the 'father' of proof theory) only student. Correspondence and a hitherto unavailable autobiographic manuscript, in addition to an unpublished article on the relationship between logic and epistemology, is presented. The chapter on Erik Stenius discusses his work on paradoxes and set theory, more specifically on how a rigid theory of definitions is employed to avoid these paradoxes. A presentation by Paul Bernays on Stenius' attempt at a proof of the consistency of arithmetic is reconstructed based on Bernays' lecture notes. Stenius correspondence with Paul Bernays, Evert Beth, and Georg Kreisel is discussed. The chapter on Georg Henrik von Wright presents his early work on probability and epistemology, along with his later work on modal logic that made him internationally famous. Correspondence from various archives (especially with Kaila and Charlie Dunbar Broad) further discusses his academic achievements and his experiences during the challenging circumstances of the 1940s.
