Aggressive Behaviour of Different Social and Demographic Groups in Post-Totalitarian Society

The project looked at aggressiveness in different age and social groups of modern post-totalitarian society, beginning with the hypotheses that the greatest risk groups are teenagers and the unemployed, and that there is a link between aggression and the level of meaningfulness of life. The groups studied comprised about 200 persons from urban areas of eastern Ukraine, including schoolchildren, students, white collar workers, self-employed persons, the unemployed and pensioners. Workers in industry were not included as this group has virtually disappeared in Ukraine at present since most enterprises have ceased to work and most workers have moved into the groups of the unemployed or self-employed. Participants were divided into age groups of 13-14, 16-17, 18-22, 24-45, 46-60 and over 60, with each group including approximately equal number of men and women. Research methods included Buss-Darky techniques, the "hand test" (E. Wagner), the "non-existent animal" technique, a Rozenzweig picture frustration study, purpose-in-life tests and an interview. The Buss-Darky test showed that schoolchildren have the highest level of aggression, followed by students. These groups have high indexes in virtually all types of aggression, including its open form. The self-employed have relatively lower indexes, although they are more likely to manifest it openly, while such open manifestations are less likely among white-collar workers, pensioners and the unemployed. The least aggressive were the unemployed and pensioners, although the latter had a relatively high level of hostility. In terms of age, aggression was shown to decrease with age, which Ms. Ivanova attributes to the still imperfect control mechanisms of teenagers and their less mature personalities. Among the younger groups girls showed a slightly higher level of aggression, although this situation was reversed among older people. The risk groups inclined to manifest open forms of aggressiveness can therefore be seen to be teenagers and students. Other tests used show aggressiveness as a feature of the current state, rather than as an inherent feature and the results obtained were somewhat different. In the interviews, all adults referred to the increased aggressiveness in society and most stated that they themselves had become more aggressive and bad-tempered. The ability of individuals to adapt to their social environment was also investigated and schoolchildren turned out to have the lowest adaptation index and the unemployed the highest. MS. Ivanova attributes that latter, rather surprising, result to the fact that the constant frustrations facing the unemployed force them to actively seek ways and means of adapting in order to survive. The final aspect considered was the possible connection between human aggressiveness and the meaningfulness of life. Here the groups with the most meaningful lives were the self-employed and pensioners. The latter result, again rather surprising, was attributed to the desire of people who have already lived the greater part of their lives to place more weight on what they have already done, in order to prove to themselves that they have not lived in vain. The hypothesis that aggressiveness is conversely related to the meaningfulness of life was only partially confirmed. In the two extreme cases (schoolchildren and pensioners) this was indeed the case, but the remaining groups did not show any such connection. From the data obtained, Ms. Ivanova concluded that life in modern post-totalitarian society does indeed foster a rise in people's aggressiveness, and this was supported by the fact that indexes of aggressiveness proved to be higher than the norm. Her original hypothesis as to the groups in society most at risk from open aggression confirmed in the case of teenagers but not of the unemployed, who had relatively low aggressiveness indexes and the highest degree of adaptation.

The Influence of the Social and Cultural Environment on a Child's Playing in the First Three Years of Life

The research focused on children's behaviour in playing with objects both independently and in interaction with adults. It was based on studies of 40 Slovene children in 4 age groups (6,12,18 and 24 months) and of 23 Croatian children in 2 age groups (18 and 24 months). All the children were sampled proportionally by their gender and the educational level of their parents (middle and higher). Several coding check lists with satisfactory internal consistency were constructed during the study and used to analyse the video-recorded playing sessions with each child. The basic conclusion reached was that even in early childhood playing behaviour differs significantly between the infants from the two Central European countries. The difference lies not so much in the structure or the content of the playing actions, but in the way in which the infants deal playfully with the objects. This difference appears regardless of the type of object the infants are playing with and even regardless of the playing condition. It can best be described as the difference between the first significant discriminant function activity versus passivity. The Slovene infants were found to be on the active pole and the Croatians on the passive one. Social and gender differences were much less significant than cultural ones in determining the structure, the content and the way of playing. Significant age differences appeared in all three aspects, which was consistent with general trends in infants' psychological development. The group define the Slovene interactive playing style as object oriented, while the Croatian one was largely communicated oriented. Within the experimenter-infant dyads, children of both cultures played at a developmentally more advanced level than they did with their mothers, showing that the mothers were not as successful at reaching the ZPD as were the trained experimenters. In addition, the children of mothers who attributed more cognitive benefit to play played on a more advanced level than those whose mothers attributed more emotional benefit to play. The quality of the object the children were playing with was also significantly related to the structure, content and partly the way of dealing with the objects. Highly-structured objects stimulated complex play and low-structured ones stimulated simple play, regardless of playing conditions. The group concluded that both culture and the quality of the available object have an important impact on young children's play. Through the playing interaction, the infants internalise culturally specific patterns of behaviour and culturally specific meanings. These internalisations become apparent very early in their lives, even in non-social situations. On the other hand, the objects themselves have an impact on the level of infants' play. When they do not provide sufficient perceptive and functional support for a representational action, the infants' play will lag behind their actual developmental capacities.

Interaction between dietary lipids and physical inactivity on insulin sensitivity and on intramyocellular lipids in healthy men

OBJECTIVE: To assess the effect of a possible interaction between dietary fat and physical inactivity on whole-body insulin sensitivity and intramyocellular lipids (IMCLs). RESEARCH DESIGN AND METHODS: Eight healthy male volunteers were studied on two occasions. After 2 days of an equilibrated diet and moderate physical activity, participants remained inactive (bed rest) for 60 h and consumed either a high-saturated fat (45% fat, of which approximately 60% was saturated fat [BR-HF]) or a high-carbohydrate (70% carbohydrate [BR-HCHO]) diet. To evaluate the effect of a high-fat diet alone, six of the eight volunteers were restudied after a 2-day equilibrated diet followed by 60 h on a high-saturated fat diet and controlled physical activity (PA-HF). Insulin sensitivity was measured by hyperinsulinemic-euglycemic clamp and IMCL concentrations by (1)H-magnetic resonance spectroscopy. RESULTS: Insulin-mediated glucose disposal was decreased by BR-HF condition (-24 +/- 6%, P < 0.05) but did not change with BR-HCHO (+19 +/- 10%, NS). BR-HF and BR-HCHO increased IMCL levels (+32 +/- 7%, P < 0.05 and +17 +/- 8%, P < 0.0011, respectively). Although the increase in IMCL levels with PA-HF (+31 +/- 19%, P = 0.12) was similar to that during BR-HF, insulin-mediated glucose disposal (-7 +/- 9%, NS) was not decreased. CONCLUSIONS: These data indicate that physical inactivity and a high-saturated fat diet may interact to reduce whole-body insulin sensitivity. IMCL content was influenced by dietary lipid and physical inactivity but was not directly associated with insulin resistance.

ECG-triggered skeletal muscle stimulation improves hemodynamics and physical performance of heart failure patients

BACKGROUND: Muscular counterpulsation (MCP) was developed for circulatory assistance by stimulation of peripheral skeletal muscles. We report on a clinical MCP study in patients with and without chronic heart failure (CHF). METHODS AND RESULTS: MCP treatment was applied (30 patients treated, 25 controls, all under optimal therapy) for 30 minutes during eight days by an ECG-triggered, battery-powered, portable pulse generator with skin electrodes inducing light contractions of calf and thigh muscles, sequentially stimulated at early diastole. Hemodynamic parameters (ECG, blood pressure and echocardiography) were measured one day before and one day after the treatment period in two groups: Group 1 (9 MCP, 11 no MCP) with ejection fraction (EF) above 40% and Group 2 (21 MCP, 14 no MCP) below 40%. In Group 2 (all patients suffering from CHF) mean EF increased by 21% (p<0.001) and stroke volume by 13% (p<0.001), while end systolic volume decreased by 23% (p<0.001). In Group 1, the increase in EF (6%) and stroke volume (8%) was also significant (p<0.05) but less pronounced than in Group 2. Physical exercise duration and walking distance increased in Group 2 by 56% and 72%, respectively. CONCLUSIONS: Noninvasive MCP treatment for eight days substantially improves cardiac function and physical performance in patients with CHF.

Social and Political Issues and the Finnish Deportees from North America

An important issue in both Canadian and United States immigration history has been the control of immigration, which includes possible quotas, immigration laws as well as denying entry, and finally, the deportation of immigrants. This paper is based on information that is available on the deportations of 167 people, most of them young adult males. Many assume politics was a key motivation for deportation. However, Finnish Americans were rarely deported for political activities. The paper discusses a few interesting cases of political deportations both during the interwar years, and after the Second World War. The information is mostly based on the correspondence between the authorities in Finland and the United States and Canada, available at the Foreign Ministry Archives in Helsinki, Finland. Special attention is directed to the social and political background of those people and of special interest are the specific reasons, social or health problems, which seem to be the basis of most deportation decisions.

AGROFORESTRY ADDRESSING SOCIAL AND ENVIRONMENTAL ISSUES IN PARAGUAY

Paraguay is characterized in part by an economy reliant on a massive soy industry and as facing social and economic challenges resulting from highly inequitable distribution of wealth and land ownership, particularly for smallholder farmers in the rural areas of the country. Yerba mate (Ilex paraguariensis), a native tree of which the leaves are used in tea, has become an increasingly common crop grown among common among smallholder farmers (owners of 10 hectares or less) as a viable alternative to soy production on a small scale. In the rural agricultural community of Libertad del Sur, located in the heart of the severely deforested Bosque Atlántico del Alto-Paraná, a series of development initiatives including tree nurseries and agroforestry projects with yerba mate were implemented with involvement of several governmental and nongovernmental organizations. Research was conducted to identify effectiveness of an agroforestry strategy to promote reforestation activities and sustainable agriculture to achieve economic and subsistence goals of the rural population. Despite a severe drought impacting initial research goals, important lessons are considered regarding promotion of development work within the community as well as community perceptions towards development agencies. Pursuit of compromise between community member and agency goals using sustainable agricultural practices is identified as an effective means to promote mutually beneficial development strategies.
