Social networks and use of social supports of minority elders in East Harlem

Considerable empirical research substantiates the importance of social networks on health and well-being in later life. A study of ethnic minority elders living in two low income public housing buildings in East Harlem was undertaken to gain an understanding of the relationship between their health status and social networks. Findings demonstrate that elders with supportive housing had better psychological outcomes and used significantly more informal supports when in need. However, elders with serious health problems had poorer outcomes regardless of their level of social support. This study highlights the potential of supportive living environments to foster social integration and to optimise formal and informal networks.

Puolustuskykyinen valtio vai Ruotsin hälytyskello? : Suomen sotilasstrateginen asema kylmän sodan alkuvuosien asiantuntija-arvioissa

The doctoral thesis deals with Finnish and foreign expert s analyses of Finland s military strategic position and defence capability, dating back to the early years of the Cold War. Finland s military high command prepared assessments of the country s strategic position and of the capability of the Defence Forces as grounds for defence planning. Since Finland was located on the Cold War dividing line, the foreign powers were also monitoring the development of Finland s situation. The research carried out had access to the armed forces internal assessments, as well as to analyses prepared by the military intelligence services of Sweden, Britain and the United States. One of the working hypotheses was that after the WWII the ability military leadership to estimate the security political needs of the country and the organisation of its defence was severely weakened so that the dangers of the international development were not perceived and the gradual erosion of defence capability was partly unnoticed. This hypothesis proved to be wrong. Even if the Finnish military intelligence was much weaker than during the war, it was able to provide the military leadership with information of the international military development for the most part. The military leadership was also fully aware of the weakening of the defence capability of the country. They faced the difficult task of making the country s political leadership, i.e. President Paasikivi and the government, also understand the gravity of the situation. Only in the last years of his term in office Paasikivi started to believe the warnings of the military. According to another hypothesis, outside observers considered the Finnish armed forces to primarily act as reinforcements for the Soviet Red Army, and they believed that, in the event of a full-scale war, the Finns would not have been able or even willing to resist a Soviet invasion of Sweden and Norway through Finland. The study confirmed that this was approximately the view the Swedes, the British and the Americans had of the Finnish forces. Western and Swedish intelligence assessments did not show confidence in Finland s defence ability and the country was regarded almost as a Soviet satellite. Finland s strategic position was, however, considered slightly different from that of the Soviet-occupied Eastern European countries. Finland had been forced to become part of the Soviet sphere of interest and security system and this was sealed by the Finno-Soviet Treaty of Friendship, Cooperation, and Mutual Assistance in 1948. Finland had little importance to the military interests of the Western powers. In Sweden s defence planning, however, Finland played a significant role as an alarm bell of a possible Soviet surprise attack, as well as defensive frontline and buffer zone.

Paimen vailla hiippakuntaa : Kenttäpiispan viran synty ja vaikutus sotilaspapiston asemaan Suomen puolustusvoimissa ja kirkossa vuosina 1939 - 1944

The main purpose of this research is to shed light on the factors that gave rise to the office of Field Bishop in the years 1939-1944. How did military bishophood affect the status of the head of military pastoral care and military clergy during these years? The main sources of my research are the collections in the Finnish National Archives, and I use a historical-qualitative method. The position of the military clergy was debated within both the Church and the Defence Forces before 1939. At that stage, Church law did not yet recognize the office of the leading military priest, the Field Dean. There had been a motion in 1932 to introduce the office of a military bishop, but the bishops' synod blocked it. The concept of Field Bishop appeared for the first time in 1927 in a Finnish military document, which dealt with pastoral care in the Polish military. The Field Dean in Finland had regularly proposed improvements to the salary of the military clergy before the Winter War. After the Winter War, arguments were made for strengthening the position of the military clergy: these arguments were based on the increased respect shown towards this clergy, especially due to their role in the care of the fallen, which had become their task during the war. Younger members of the military clergy in particular supported the demands to improve their position within the Church and the army. The creation of a Field Bishop was perceived as strengthening the whole military clergy, as the Field Bishop was envisioned as a bishop within the Church and a general within the Defence Forces. During that time the Field Dean was still without any military rank. The idea of a Field Bishop was recommended to Mannerheim in June 1940, after which the Defence Forces lent their support to the cause. The status of the military clergy, in Church law, made it to the agenda of the Church council in January 1941, thanks largely to the younger priests' group influence and Mannerheim's leverage. The bishops opposed the notion of a Field Bishop mostly on theological grounds but were ready to concede that the position the Field Dean in Church law required further defining. The creation of the office of Field Bishop was blocked in the Church law committee report issued close to the beginning of the Continuation War. The onset of that war, however, changed the course of events, as the President of the Republic appointed Field Dean Johannes Björklund as Field Bishop. Speculation has abounded about Mannerheim's role in the appointment, but the truth of the matter is not clear. The title of Field Bishop was used to put pressure on the Church, and, at the same time, Mannerheim could remain detached from the matter. Later, in September 1941, the Church council approved the use of the Field Bishop title to denote the head of military pastoral care in Church law, and Field Bishops were assigned some of the duties formerly pertaining to bishops. Despite all expectations and hopes, the new office of Field Bishop did not affect the status of the military clergy within the Defence Forces, as no ranks were established for them, and their salary did not improve. However the office of the Field Bishop within Army HQ was transformed from a bureau into a department in the summer of 1942. At the beginning of the Continuation War, the Field Bishop was criticized by certain military and Church clergy for favouring Russian Orthodox Christians in Eastern Karelia. Björklund agreed in principle with most of the Lutheran clergy on the necessity of Lutheranizing East Karelia but had to take into account the realities at Army HQ. As well, at the same time the majority of the younger clergy were serving in the army, and there was a lack of parish priests on the home front. Bishop Lehtonen had actually expressed the wish that more priests could have been released from the front to serve in local parishes. In his notes Lehtonen accused Björklund of trying to achieve the position of Field Bishop by all possible means. However, research has revealed a varied group of people behind the creation of the office of Field Bishop, including in particular younger clergy and the Defence Forces.

Complete Pick positivity and unitary invariance

The characteristic function for a contraction is a classical complete unitary invariant devised by Sz.-Nagy and Foias. Just as a contraction is related to the Szego kernel k(S) (z, w) = (1 - z (w) over tilde)(-1) for |z|, |w| < 1, by means of (1/k(S))(T,T*) >= 0, we consider an arbitrary open connected domain Omega in C-n, a complete Pick kernel k on Omega and a tuple T = (T-1, ..., T-n) of commuting bounded operators on a complex separable Hilbert space H such that (1/k)(T,T*) >= 0. For a complete Pick kernel the 1/k functional calculus makes sense in a beautiful way. It turns out that the model theory works very well and a characteristic function can be associated with T. Moreover, the characteristic function is then a complete unitary invariant for a suitable class of tuples T.

Enhancement in Bath Mixing and Plume area in a New Degassing Process - A Computational Fluid Dynamic Study

Reaction between the various species in slag and metal phase is usually mass transfer controlled. There have been continuous efforts to increase the reaction efficiency in slag-metal system, especially during decarburization of steel to produce the ultra low carbon steel (ULCS) in secondary steelmaking. It has been found that the surface reaction is a dominant factor in the final stage of decarburization. In the initial stage, the inner site reaction is major factor in the refining process. The mixing of bath affects the later reaction. However, the former reaction (surface reaction) is affected by the plume size area at the top of the metal surface. Therefore, a computational study has been made to understand the fluid dynamics of a new secondary steelmaking process called Revolutionary Degasser Activator (REDA) to study the bath mixing and plume area. REDA process has been considered as it is claimed that this process can reduce the carbon content in steel below 10ppm in a less time than the other existing processes such as RH and Tank degasser. This study shows that both bath mixing and plume area are increased in REDA process facilitating it to give the desired carbon content in less time. Qualitative comments are made on slag-metal reaction system based on this finding.

Solutions of cubic equations in quadratic fields

Let K be any quadratic field with O-K its ring of integers. We study the solutions of cubic equations, which represent elliptic curves defined over Q, in quadratic fields and prove some interesting results regarding the solutions by using elementary tools. As an application we consider the Diophantine equation r + s + t = rst = 1 in O-K. This Diophantine equation gives an elliptic curve defined over Q with finite Mordell-Weil group. Using our study of the solutions of cubic equations in quadratic fields we present a simple proof of the fact that except for the ring of integers of Q(i) and Q(root 2), this Diophantine equation is not solvable in the ring of integers of any other quadratic fields, which is already proved in [4].

On isometries of the Kobayashi and Caratheodory metrics

This article considers C-1-smooth isometries of the Kobayashi and Caratheodory metrics on domains in C-n and the extent to which they behave like holomorphic mappings. First we provide an example which suggests that B-n cannot be mapped isometrically onto a product domain. In addition, we prove several results on continuous extension of C-0-isometries f : D-1 -> D-2 to the closures under purely local assumptions on the boundaries. As an application, we show that there is no C-0-isometry between a strongly pseudoconvex domain in C-2 and certain classes of weakly pseudoconvex finite type domains in C-2.

Variation of Electrical Resistivity with High Pressure in Ge-Te-Sn Glasses: A Composition Dependent Study

The variation of normalized electrical resistivity in the system of glasses Ge15Te85-xSnx with (1 <= x <= 5) has been studied as a function of high pressure for pressures up to 9.5 GPa. It is found that with the increase in pressure, the resistivity decreases initially and shows an abrupt fall at a particular pressure, indicating the phase transition from semiconductor to near metallic at these pressures, which lie in the range 1.5-2.5 GPa, and then continues being metallic up to 9.5 GPa. This transition pressure is seen to decrease with the increase in the percentage content of tin due to increasing metallicity of tin. The semiconductor to near metallic transition is exactly reversible and may have its origin in a reduction of the band gap due to high pressure.

Interactions of CO, HCl, and Sox in Pulverised Coal Flames

The effect of HCl and SO_2 on CO oxidation in pulverised coal flames was investigated experimentally and kinetically in an entrained flow combustion reactor. Two bituminous coals (German 'Goettelborn' and a Polish coal) were used as fuels with a feeding rate of 1 or 1.5 kg/h. HCl or SO_2 is introduced into the reactor premixed with the primary air. Experimental results indicate that HCl addition may inhibit CO oxidation in coal flames and increases CO emission. Reducing temperature in the reactor will enhance the inhibitory effect of HCl on CO oxidation. The measured CO profiles along the reactor height clearly show that the addition of HCl may inhibit CO oxidation. In the experimental range of SO_2 addition. The inhibiting effect of SO_2 on CO oxidation is less significant than HCl. A detailed kinetic mechanism is used to model the reactions. And the controlling reactions are analysed.
