Ystävä sä lapsien : Lasten virret ja hengelliset laulut suomenkielisissä kokoelmissa 1824-1938 ja niiden vaikutus vuoden 1938 virsikirjaan

Ystävä sä lapsien. Collections of Finnish language children s hymns and spiritual songs from 1824─1938 and their influence on the Hymnal 1938. The Hymnal has been the common song book of Lutheran parishes since the 1500s. In the beginning, the congregations sang the hymns from memory led by the choir or the church musician. The fundamentals of Christian faith are taught through the hymns, both in church and in family devotions. The Hymnal was the only song book of the church in Finland until the end of the 1800s. This study attempts to clarify when and by who were spiritual songs and hymns for children written in Finland. Research materials used were all the books I could find (approximately 200), whose headings were for pupils and young children in the home and school circles. The method of study is historical and analytical. In the first chapter, it is explained that children s literature in Finland differentiated from other literature at the end of the 1700s. Eric Juvelius published a small prayer book in 1781 with the prayer Gud, som hafver barnen kär / Jumala joka Lapsia rakasta. From that, after many Finnish translations, the first verse of the hymn Ystävä sä lapsien took shape. The second chapter considers singing instruction in the folk school from the beginning of the 1860s. Textbooks, including songbooks, were produced for the pupils. Some of the first pioneers in producing these materials were the teachers P.J. Hannikainen, Sofie Lithenius, Mikael Nyberg, Anton Rikström and Aksel Törnudd, as well as Hilja Haahti, Immi Hellén and Alli Nissinen, who were all teachers gifted in writing poetry. Several new spiritual songs appeared in the folk school songbooks. Hymns were sung often, especially in connection with church year celebrations. Children s songs in Christian education are discussed in the third chapter. The Lutheran Evangelical Association of Finland recognized children already in its early song collections. The illustrative teaching methods in the folk school influenced the Sunday school activities and especially the Sunday school hymns. Hymns introduced as exclusively for children and pupils which appear in the Hymnal from 1886 and the supplement to the 1923 Hymnal are explored in the fourth and fifth chapters. The study shows that the renewal of church life at the beginning of the 1900s also resulted in an increase of the number of spiritual songs for children. This is also seen in the diverse choice of songs in the supplementary materials from 1923. The final chapter deals with the School and Childhood section of the 1938 Hymnal. The Hymnal committee did not think that the already well known folk school and Sunday school songs received enough attention in the Hymnal. Those songs were, among others, Kautta tyynen, vienon yön, Oi, katsopa lintua oksalla puun, Olen Luojani pikku varpunen, Rakas Isä taivahan ja Tuolla keinuu pieni pursi. Heikki Klemetti, Ilmari Krohn, Armas Maasalo and Aarni Voipio influenced the opinion that the spiritual songs still were not suitable to be sung in church. Hymns for children and pupils were brought into the same line as the entire Hymnal. The same hymn tunes, which were mainly old ones, were used as common settings for numerous hymn texts. No special type of melody emerged for the children s hymns. It was still notable that hymns for children and pupils were collected at all. In addition, the Hymnal committee marked those verses suggested for singing in both the folk school and Sunday school with an asterisk (*) throughout the entire Hymnal.

Dry sliding wear behavior of Al2O3 fiber reinforced aluminum composites

Dry sliding wear behavior of die-cast ADC12 aluminum alloy composites reinforced with short alumina fibers were investigated by using a pin-on-disk wear tester. The Al2O3 fibers were 4 mu m in diameter and were present in volume fractions (T-f)ranging from 0.03 to 0.26, The length of the fiber varied from 40 to 200 mu m. Disks of aluminum-alumina composites were rubbed against a pin of nitrided stainless steel SUS440B with a load of 10 N at a sliding velocity of 0.1 m/s. The unreinforced ADC 12 aluminum alloy and their composites containing low volume fractions of alumina (V-f approximate to 0.05) showed a sliding-distance-dependent transition from severe to mild wear. However, composites containing high volume fractions of alumina ( V-f > 0.05) exhibited only mild wear for all sliding distances. The duration of occurrence of the severe wear regime and the wear rate both decrease with increasing volume fraction. In MMCs the wear rate in the mild wear regime decreases with increase in volume fraction: reaching a minimum value at V-f = 0.09 Beyond V-f = 0.09 the wear rate increasesmarginally. On the other hand, the wear rate of the counterface (steel pin) was found to increase moderately with increase in V-f. From the analysis of wear data and detailed examination of (a) worn surfaces, (b) their cross-sections and (c) wear debris, two modes of wear mechanisms have been identified to be operative, in these materials and these are: (i) adhesive wear in the case of unreinforced matrix material and in MMCs with low Vf and (ii) abrasive wear in the case of MMCs with high V-f.

"Helvetti on kiistaton, mutta taivas on suhteellinen." : Uskonnollisten ihanteiden ja kokemuksen välinen ristiriita L. M. Montgomeryn elämässä vuosina 1921 1927

Tässä tutkimuksessa tutkittiin kanadalaisen kirjailijan L. M. Montgomeryn (1874 1942) elämää vuosina 1921 1927. Kyseisinä vuosina Montgomery eli presbyteeripapin vaimona maaseutuseurakunnissa, ensin Leaskdalessa ja sitten Norvalissa Kanadan Ontariossa. Tutkimus keskittyi tarkastelemaan kirjailijan elämää hallinnutta ristiriitaa, joka muodostui uskonnollisten ihanteiden ja yksilöllisen kokemuksen välisistä eroavaisuuksista. Primäärilähteinä olivat Montgomeryn toimitetut ja julkaistut päiväkirjat The Selected Journals of L. M. Montgomery 1 5 (1985 2004), joista käytettiin etenkin tutkimusvuosiin keskittyvää kolmatta osaa, Montgomeryn neljä romaania Emily of New Moon (1923), Emily Climbs (1925), Blue Castle (1926) ja Emily's Quest (1927) sekä Montgomeryn toimitettu ja julkaistu kirjeenvaihto After Green Gables: L. M. Montgomery's Letters to Ephraim Weber , 1916 1941 (2006) ja My Dear Mr. M.: Letters to G. B. MacMillan (1980). Lisäksi lähteinä oli Leaskdalen seurakuntalaisten kokoama muistelmateos Montgomerysta. Kirjallisuutta käytettiin kirkkohistorian, kirjallisuudentutkimuksen ja naistutkimuksen alalta. Suositusta kirjailijasta on tehty useampia elämäkertoja ja niitä hyödynnettiin tutkimuksessa. Tutkimus jakautui kahteen päälukuun, jotka toimivat toistensa vastaparina. Ensimmäinen tutkimusluku keskittyi tarkastelemaan uskonnollisia ja viktoriaanisia ihanteita, joiden mukaisesti Montgomery oli saanut kasvatuksen. Hän pyrki täyttämään näitä ihanteita myös pappilan emäntänä. Toinen tutkimusluku tarkasteli kirjailijan elämää, uskonnollisia ajatuksia ja avioliittoa julkisivun takana, jolloin kävi selvästi ilmi kirjailijan kahtiajakautunut elämä. Montgomery sai presbyteerisen ja viktoriaanisen kasvatuksen ja oppi jo lapsena huomioimaan sen, mitä muut ihmiset ajattelevat hänestä. Hän eli pienissä maaseutuyhteisöissä, joissa juoruilu oli yksi kontrollin väline. Papin vaimolla oli velvollisuuksia seurakunnassa ja pappilan hoidossa, ja Montgomery hoiti ne tarmokkaasti ja velvollisuudentuntoisesti. Hänellä oli apulainen pappilassa, jossa arki sujui viikkoaikataulun mukaisesti. Papin vaimon roolin lisäksi Montgomery jatkoi omaa kirjoittamistyötään ja hänen runsaat tulonsa mahdollistivat nelihenkisen perheen monet hankinnat. Hänen avioliittonsa oli vaikea, sillä aviomies kärsi uskonnollisesta melankoliasta ja asia piti salata seurakuntalaisilta. Montgomery käsittelee uskonnollisia teemoja romaaneissaan ja päiväkirjassaan. Hänen uskonnolliset ajatuksensa erosivat presbyteerikirkon opista useassa kohdin. Hän ei uskonut moneenkaan opinkappaleeseen, kohtasi Jumalan ennemmin luonnossa ollessaan yksin kuin kirkossa seurakunnan keskellä sekä ajatteli kristinuskon olevan jäännös menneestä ja tieteen ottaneen sen paikan Jumalan toiminnan kanavana. Kirjailijan ajattelussa on yhtymäkohtia transsendentalismiin, teosofiaan ja darwinismiin. Hän oli innokas psykologisen kirjallisuuden lukija ja sovelsi oppejaan käytäntöön. Hän uskoi unien välittävän viestejä. Kirkkokunta oli hänelle kuitenkin merkittävä identiteetin rakentaja. Papin vaimon roolin ja yksityisesti kriittisen ajattelijan roolin yhteensovittaminen aiheutti Montogmerylle ongelmia ja väsymystä. Hän kätki uskonnolliset ajatuksensa ja yksinäisyyden aiheuttaman kivun päiväkirjaansa, jonka hän toivoi julkaistavan viimeistään kuolemansa jälkeen. Kaikenlainen kirjoittaminen oli hänelle pakoa todellisuudesta ja auttoi häntä jaksamaan. Otsikon sitatti kuvaa Montgomeryn suhdetta kristinuskoon: hän käytti kristillisiä ilmauksia, mutta muokkasi niiden sisältöä omaa uskoaan vastaavaksi. Taivas ja helvetti kuvasivat usein hänen henkistä olotilaansa sanojen uskonnollisen merkityksen sijasta.

Paradigms in Statistical Inference for Finite Populations; Up to the 1950s

Modern sample surveys started to spread after statistician at the U.S. Bureau of the Census in the 1940s had developed a sampling design for the Current Population Survey (CPS). A significant factor was also that digital computers became available for statisticians. In the beginning of 1950s, the theory was documented in textbooks on survey sampling. This thesis is about the development of the statistical inference for sample surveys. For the first time the idea of statistical inference was enunciated by a French scientist, P. S. Laplace. In 1781, he published a plan for a partial investigation in which he determined the sample size needed to reach the desired accuracy in estimation. The plan was based on Laplace s Principle of Inverse Probability and on his derivation of the Central Limit Theorem. They were published in a memoir in 1774 which is one of the origins of statistical inference. Laplace s inference model was based on Bernoulli trials and binominal probabilities. He assumed that populations were changing constantly. It was depicted by assuming a priori distributions for parameters. Laplace s inference model dominated statistical thinking for a century. Sample selection in Laplace s investigations was purposive. In 1894 in the International Statistical Institute meeting, Norwegian Anders Kiaer presented the idea of the Representative Method to draw samples. Its idea was that the sample would be a miniature of the population. It is still prevailing. The virtues of random sampling were known but practical problems of sample selection and data collection hindered its use. Arhtur Bowley realized the potentials of Kiaer s method and in the beginning of the 20th century carried out several surveys in the UK. He also developed the theory of statistical inference for finite populations. It was based on Laplace s inference model. R. A. Fisher contributions in the 1920 s constitute a watershed in the statistical science He revolutionized the theory of statistics. In addition, he introduced a new statistical inference model which is still the prevailing paradigm. The essential idea is to draw repeatedly samples from the same population and the assumption that population parameters are constants. Fisher s theory did not include a priori probabilities. Jerzy Neyman adopted Fisher s inference model and applied it to finite populations with the difference that Neyman s inference model does not include any assumptions of the distributions of the study variables. Applying Fisher s fiducial argument he developed the theory for confidence intervals. Neyman s last contribution to survey sampling presented a theory for double sampling. This gave the central idea for statisticians at the U.S. Census Bureau to develop the complex survey design for the CPS. Important criterion was to have a method in which the costs of data collection were acceptable, and which provided approximately equal interviewer workloads, besides sufficient accuracy in estimation.

Nonlinear measures of QT interval series: novel indices of cardiac repolarization lability: MEDqthr and LLEqthr

In this study, we investigated nonlinear measures of chaos of QT interval time series in 28 normal control subjects, 36 patients with panic disorder and 18 patients with major depression in supine and standing postures. We obtained the minimum embedding dimension (MED) and the largest Lyapunov exponent (LLE) of instantaneous heart rate (HR) and QT interval series. MED quantifies the system's complexity and LLE predictability. There was a significantly lower MED and a significantly increased LLE of QT interval time series in patients. Most importantly, nonlinear indices of QT/HR time series, MEDqthr (MED of QT/HR) and LLEqthr (LLE of QT/HR), were highly significantly different between controls and both patient groups in either posture. Results remained the same even after adjusting for age. The increased LLE of QT interval time, series in patients with anxiety and depression is in line with our previous findings of higher QTvi (QT variability index, a log ratio of QT variability corrected for mean QT squared divided by heart rate variability corrected for mean heart rate squared) in these patients, using linear techniques. Increased LLEqthr (LLE of QT/HR) may be a more sensitive tool to study cardiac repolarization and a valuable addition to the time domain measures such as QTvi. This is especially important in light of the finding that LLEqthr correlated poorly and nonsignificantly with QTvi. These findings suggest an increase in relative cardiac sympathetic activity and a decrease in certain aspects of cardiac vagal function in patients with anxiety as well as depression. The lack of correlation between QTvi and LLEqthr suggests that this nonlinear index is a valuable addition to the linear measures. These findings may also help to explain the higher incidence of cardiovascular mortality in patients with anxiety and depressive disorders. (C) 2002 Elsevier Science Ireland Ltd.

Charge-transfer interaction mediated organogels from bile acid appended anthracenes: rheological and microscopic studies

In this article we present dual-component charge-transfer interaction (CT) induced organogel formation with bile acid anthracene conjugates as donors and 2,4,7-trinitrofluorenone (TNF) as the acceptor. The use of TNF (1) as a versatile electron acceptor in the formation of gels is demonstrated through the formation of gels with different steroidal groups on the anthracene moiety in a variety of solvents ranging from aromatic hydrocarbons to long chain alcohols. Thermal stability and variable temperature fluorescence experiments were performed on these CT gels. Dynamic rheological experiments conducted on these gels suggest that these are viscoelastic soft materials and with the gel strength can be modulated by varying the donor/acceptor ratios.

Development of a New Generation of Vectors for Gene Expression, Gene Replacement, and Protein-Protein Interaction Studies in Mycobacteria

Escherichia coli-mycobacterium shuttle vectors are important tools for gene expression and gene replacement in mycobacteria. However, most of the currently available vectors are limited in their use because of the lack of extended multiple cloning sites (MCSs) and convenience of appending an epitope tag(s) to the cloned open reading frames (ORFs). Here we report a new series of vectors that allow for the constitutive and regulatable expression of proteins, appended with peptide tag sequences at their N and C termini, respectively. The applicability of these vectors is demonstrated by the constitutive and induced expression of the Mycobacterium tuberculosis pknK gene, coding for protein kinase K, a serine-threonine protein kinase. Furthermore, a suicide plasmid with expanded MCS for creating gene replacements, a plasmid for chromosomal integrations at the commonly used L5 attB site, and a hypoxia-responsive vector, for expression of a gene(s) under hypoxic conditions that mimic latency, have also been created. Additionally, we have created a vector for the coexpression of two proteins controlled by two independent promoters, with each protein being in fusion with a different tag. The shuttle vectors developed in the present study are excellent tools for the analysis of gene function in mycobacteria and are a valuable addition to the existing repertoire of vectors for mycobacterial research.

Universal Hashing for Information-Theoretic Security

The information-theoretic approach to security entails harnessing the correlated randomness available in nature to establish security. It uses tools from information theory and coding and yields provable security, even against an adversary with unbounded computational power. However, the feasibility of this approach in practice depends on the development of efficiently implementable schemes. In this paper, we review a special class of practical schemes for information-theoretic security that are based on 2-universal hash families. Specific cases of secret key agreement and wiretap coding are considered, and general themes are identified. The scheme presented for wiretap coding is modular and can be implemented easily by including an extra preprocessing layer over the existing transmission codes.

Orientation Selection and Microstructural Evolution in Directionally Solidified Tb0.3Dy0.7Fe1.95

Tb0.3Dy0.7Fe1.95 alloy was directionally solidified by using a modified Bridgman technique at a wide range of growth rates of 5 to 100 cm/h. The directionally grown samples exhibited plane front solidification morphology up to a growth rate of 90 cm/h. Typical island banding feature was observed closer to the chilled end, which eventually gave rise to irregular peritectic coupled growth (PCG). The PCG gained prominence with an increase in the growth rate. The texture study revealed formation of strong aOE (c) 311 > texture in a lower growth rate regime, aOE (c) 110 > and ``rotated aOE (c) 110 > aEuroe in an intermediate growth regime, and aOE (c) 112 > in a higher growth rate regime. In-depth analysis of the atomic configuration of a solid-liquid interface revealed that the growth texture is influenced by the kinetics of atomic attachment to the solid-liquid interface, which is intimately related to a planar packing fraction and an atomic stacking sequence of the interfacial plane. The mechanism proposed in this article is novel and will be useful in addressing the orientation selection mechanism of topologically closed packed intermetallic systems. The samples grown at a higher growth rate exhibit larger magnetostriction (lambda) and d lambda/dH owing to the absence of pro-peritectic (Tb,Dy)Fe-3 and formation of aOE (c) 112 > texture, which lies closer to the easy magnetization direction (EMD).

Diagnóstico agronómico del sistema de producción de frijol (Phaseolus vulgaris L) en tres localidades representativas del municipio de Ticuantepe, Managua, Nicaragua

El presente estudio se desarrolló durante la época de postrera (1996) en la zona de Ticuantepe, Managua, en las localidades de Buenos Aires, El Edén y Cebadilla, con los objetivos de conocer y profundizar en la problemática agronómica y socioeconómica que se presenta en la producción de frijol (Phaseolus vulgaris L) en el área de estudio, y específicamente investigar que factores de producción están limitando el potencial de rendimiento del cultivo. Como criterio principal se consideró el nivel tecnológico de los productores, definiendo tres grupos de tecnología: tecnología alta, tecnología media y tecnología baja. Se tomaron como muestra veinte productores. La información se recolectó a través de encuesta semi-estructurada, abordando los aspectos involucrados en la producción de frijol tanto agronómicos como socioeconómicos, se aplicó una hoja de campo para analizar los componentes del rendimiento, se calculó la producción estimada para realizar análisis de rendimiento y rentabilidad del cultivo al igual que se realizaron consultas con las instituciones de apoyo al agro que se desempeñan en la zona en diversos aspectos. Los resultados del estudio muestran que existe poca asistencia técnica de parte de las instituciones de apoyo a la agricultura y ausencia de planes de apoyo crediticio de cualquier modalidad. En referencia al manejo agronomico el estudio mostro que existen deficiencias especialmente en lo que se refiere a la fertilización, manejo de plagas y enfermedades debido a la falta de conocimientos basicos de los productores en estos aspectos. De igual forma los criterios de fertilización no están bien definidos, por lo que es comun el mal uso de formulas y dosis del fertilizante. Los productores de tecnologia alta presentan buena rentabilidad con un promedio de 359.21 por ciento de acuerdo a los rendimientos estimados y valor de venta del producto. De igual forma los productores de tecnología media obtienen buena rentabilidad con un promedio de 281.4 por ciento, a excepción de un productor que obtuvo rentabilidad negativa (24.90). Los productores de tecnología baja tienen los rendimientos estimados y rentabilidades más bajas con un promedio de 169.64 por ciento, y aún así, de ocho productores solo tres obtienen rentabilidad negativa (25.4, 47.60 y 22.10 por ciento), lo que demuestra que el cultivo de frijol si es un cultivo rentable a pesar de las diferentes problemáticas que presentan los productores, al igual que se perfila como un cultivo que pasa a ser de subsistencia a un cultivo que genera ganancias.

Prueba de envejecimiento acelerado para evaluar calidad de semillas de diferentes materiales genéticos de frijol (Phaseolus vulgaris L.)

El presente trabajo se realizó en Geneticos Nicaraguenses (REGEN) adscrito Nacional Agraria a finales de 1995 con el la Prueba de Envejecimiento Acelerado (PEA) el Programa a la Universidad propósito de utilizar de semillas como una herramienta más para evaluar vigor, atributo relacionado con la emergencia en campo y la almacenabilidad de las mismas. El estudio se realizó con seis variedades (dos mejoradas modernas y cuatro locales o tradicionales) sometidas a condiciones de envejecimiento acelerado a fin de diferenciar los genotipos en base a su comportamiento después de la prueba mencionada. Se evaluaron en laboratorio y en campo en un diseño completamente al azar, las variables siguientes: Germinación estándar. número de plantas emergidas. velocidad de emergencia, materia seca de plántulas y de raíces. Del análisis de los resultados se llego a las conclusiones siguientes: 1) De manera general. la PA permitió hacer una diferenciación entre los materiales estudiados: las variedades locales mostraron un comportamiento superior con relación a las mejoradas. 2) La variedad local "Chile" se vio menos afectada por la PEA considerándose como un material muy vigoroso y con alto potencial de almacenamiento. ) La reducción de la terminación inicial de las variedades locales después de la PEA fue hasta un 24%. en cambio para las mejoradas fue mayor de un 48%. 4)Las variables materia seca de plántula y de raíz no permitieron valorar objetivamente la calidad de las semillas debido a las variaciones observadas. 5) Al correlacionar los resultados de la Prueba de Germinación Estándar y de la PEA con la emergencia en campo, la primera mostró un mayor coeficiente de correlación (0.98 **)con relación a la segunda prueba (0.82*). 6) A fin de mejorar la metodología de la PEA se recomienda, para llegar a conclusiones más definitivas, uniformizar ciertos parámetros de las semillas de los materiales genéticos sujetos a estudio como son: Calidad fisiológica Inicial, contenido de humedad Inicial, condiciones previas de almacenamiento, color de testa, rugosidad etc.

The interaction between poly(vinylpyrrolidone) and reversed micelles of water/AOT/n-heptane

The interactions between poly(vinylpyrrolidone) (PVP) and the reversed micelles composed of water, AOT, and n-heptane are investigated with the aid of phase diagram, measurements of conductivity and viscosity, Fourier transform infrared (FTIR) spectrum, and dynamic light scattering (DLS). The phase diagrams of water/AOT/heptane in the presence of and absence of PVP are given. The conductivity of the water/AOT/heptane reversed micelle without PVP initially increases and then decreases with the increase of water content, ω0 (the molar ratio of water to AOT), while the plots of conductivity (K) versus ω0 of the reversed micelle in the presence of PVP depend on the PVP concentrations. The plot of K versus ω0 with 2.0%wt PVP is similar to that without PVP. Only the ω0,max (the water content that the maximum conductivity corresponds to) is larger than that without PVP. Nevertheless, the conductivity of the reversed micelle containing more than 4%wt PVP always rises with the increase of the water content in the measured range. The DLS results indicate that the hydrodynamic radius (Rh) in the presence and absence of PVP rises with the increase of ω0. The plots with PVP and without PVP have almost the same value when ω0<17; and after that, it quickly increases with the increase of ω0. It is interesting to find that there is almost no effect of the PVP concentration on the viscosity and Rh of the reversed micelle at ω0 = 15. The FTIR results suggest that the contents of SO3--bound water and Na+-bound water both decrease with PVP added, while the content of the bulky-like water increases. However, the trapped water in the hydrophobic chain of the surfactant is nearly unaffected by PVP. It is also found from the FTIR that the carbonyl group stretching vibration of AOT is fitted into two sub-peaks, which center at 1740 and 1729 cm-1, corresponding to the trans and cis conformations of AOT, respectively.
