Prostaglandin treatment at the onset of norgestomet and estradiol-based synchronization protocols did not alter the ovarian follicular dynamics or pregnancy per timed artificial insemination in cyclic Bos indicus heifers

The aim of the present study was to evaluate the effects of the PGF2˛treatment givenat the onset of a synchronization of ovulation protocol using a norgestomet (NORG) earimplant on ovarian follicular dynamics (Experiment 1) and pregnancy per AI (P/AI; Exper-iment 2) in cyclic (CL present) Bos indicus heifers. In Experiment 1, a total of 46 heiferswere presynchronized using two consecutive doses of PGF2˛12 days apart. At first dayof the synchronization protocol the heifers received implants containing 3 mg of NORGand 2 mg of estradiol benzoate (EB). At the same time, heifers were randomly assignedto receive 150 mg of d-cloprostenol (n = 23; PGF2˛) or no additional treatment (n = 23;Control). When the ear implants were removed 8 days later, all heifers received a PGF2˛treatment and 1 mg of EB was given 24 h later. The follicular diameter and interval toovulation were determined by transrectal ultrasonography. No effects of PGF2˛treat-ment on the diameter of the largest follicle present were observed at implant removal(PGF2˛= 9.8 ± 0.4 vs. Control = 10.0 ± 0.3 mm; P = 0.73) or after 24 h (PGF2˛= 11.1 ± 0.4 vs.Control = 11.0 ± 0.4 mm; P = 0.83). No differences in the time of ovulation after ear implantremoval (PGF2˛= 70.8 ± 1.2 vs. Control = 73.3 ± 0.9 h; P = 0.10) or in the ovulation rate(PGF2˛= 87.0 vs. Control = 82.6%; P = 0.64) between treatments were observed. In Experi-ment 2, 280 cyclic heifers were synchronized using the same experimental design describedabove (PGF2˛; n = 143 and Control; n = 137), at random day of the estrous cycle. All heifersreceived 300 IU of equine chorionic gonadotropin (eCG) and 0.5 mg of estradiol cypionate(as ovulatory stimulus) when the NORG ear implants were removed. Timed artificial insem-ination (TAI) was performed 48 h after implant removal and the pregnancy diagnosis wasconducted 30 days later. No effects on the P/AI due to PGF2˛treatment were observed(PGF2˛= 51.7 vs. Control = 57.7%; P = 0.29). In conclusion, PGF2˛treatment at the onset ofNORG-based protocols for the synchronization of ovulation did not alter the ovarian follic-ular responses or the P/AI in cyclic Bos indicus beef heifers synchronized for TAI.

Interethnic Interaction Dynamics in the Russian Federation

The collapse of the Soviet Union at the beginning of the 1990s also meant the end of the idea of a common soviet identity incarnated in the "soviet man" and the new "historic community of the soviet people". While this idea still lives on in the generations of the 1920s to 1940s, the younger generations tend to prefer identification with family, profession, ethnic group or religion. Ms. Alexakhina set out to investigate different interethnic interaction strategies in the multi-ethnic context of the Russian Federation, with an emphasis on analysing the role of cultural and ethno-demographic characteristics of minority ethnic groups. It aimed to identify those specific patterns of interaction dynamics that have emerged in response to the political and economic transformation at present under way. The basic supposition was that the size and growth of an ethnic population are defined not only by demographic features such as fertility, mortality and net migration, but are also dependent on processes interethnic interaction and ethnic transition. The central hypothesis of the project was that the multi-ethnic and multi-cultural composition of Russia is apparently manifesting itself in the ethnic minority groups in various forms, but particularly in the form of ethnic revival and/or assimilation. The results of these complex phenomena are manifested as changes in ethnic attachments (national re-identification and language behaviour (multi-lingualism, language transition and loss of the mother tongue). The stress of the political and economic crisis has stimulated significant changes in ethnographic, social and cultural characteristics of inter-ethnic dynamics such as the rate of national re-identification, language behaviour, migration activity and the spread of mixed marriages, among both those minorities with a long history of settlement in Russia and those that were annexed during the soviet period. Patterns of language behaviour and the spread of mixed marriages were taken as the main indicators of the directions of interethnic interaction described as assimilation, ethnic revival and cultural pluralism. The first stage of the research involved a statistical analysis of census data from 1959 to 1994 in order to analyse the changing demographic composition of the largest ethnic groups of the Russian Federation. Until 1989 interethnic interaction in soviet society was distinguished by the process of russification but the political and economic transformation has stimulated the process of ethnic revival, leading to an apparent fall in the size of the Russian population due to ethnic re-identification by members of other ethnic groups who had previously identified themselves as Russian. Cross-classification of nationalities by demographic, social and cultural indicators has shown that the most important determinants of the nature of interethnic interaction are cultural factors such as religion and language affiliation. The analysis of the dynamics of language shift through the study of bilingualism and the domains of language usage for different demographic groups revealed a strong correlation between recognition of Russian as a mother tongue among some non-Russian ethnic groups and the declining size of these groups. The main conclusion from this macro-analysis of census data was the hypothesis of the growing importance of social and political factors upon ethnic succession, that ethnic identity is no longer a stable characteristic but has become dynamic in nature. In order to verify this hypothesis Ms. Alexakhina conducted a survey in four regions showing different patterns of interethnic interaction: the Karelian Republic, Buryatiya, the Nenezkii Autonomous Region and Tatarstan. These represented the west, east, north and south of the Russian Federation. Samples for the survey were prepared on the basis of census lists so as to exclude mono-Russian families in favour of mixed and ethnic-minority families. The survey confirmed the significant growth in the importance of ethnic affiliation in the everyday lives of people in the Federation following the de-centralisation of the political and economic spheres. Language was shown to be a key symbol of the consciousness of national distinction, confirmed by the fact that the process of russification has been reversed by the active mastering of the languages of titular nationalities. The results also confirmed that individual ethnic identity has ceased to be a fixed personal characteristic of one's cultural and genetic belonging, and people's social adaptation to the current political, social and economic conditions is also demonstrated in changes in individual ethnic self-identification. In general terms, the dynamic nature of national identity means that ethnic identity is at present acquiring the special features of overall social identity, for which the frequent change of priorities is an inherent feature of a person's life cycle. These are mainly linked with a multi-ethnic environment and high individual social mobility. From her results Ms. Alexakhina concludes that the development of national languages and multi-lingualism, together with the preservation of Russian as a state language, seems to be the most promising path to peaceful coexistence and the development of the national cultures of different ethnic groups within the Russian Federation.

Reading Readings: An Approach to the Relationship between Television and Literature at School

The main problem addressed by this research was that of what are the relations between TV viewing at home and studying literature at school, and how an adequate position on this can be reached. As well as the theoretical background, it involved an experimental study with classes of second and sixth grade students, discussing and observing their reactions to and interpretations of a number of animated cartoons. The work is divided into four parts - Is there a Class in this Text?, Stories of Reading, Narratives of Animation and Animation of Narratives, and The (Three) Unrepeatable (Pigs). Beginning, Middle End - which examine the tensions between the "undiscriminating sequence" of the televisual flow and a way of "thinking", "making" and "doing" education that presupposes a fundamental belief in possible re-productions, copies unescaping, following the original, or competing. The work focuses on animated cartoons, seeing them not merely as a part of the flow of television, but as an allegory of reading this flow, of the flow within the flow itself. What they question - "identity", "end", "followability" - is what is most important to teaching. Thus the interest in the metamorphoses of animated films is an interest in the tensions which their "strange law/flow" introduces into the field of teaching - this totally forbidden place of saying everything.

The Semantics and Typology of Yes/No Particles (A Cross-Linguistic Study)

Taking the three basic systems of Yes/No particles the group looked at the relative deep and surface structures, and asked what types of systems are present in the Georgian, Polish and Armenian languages. The choice of languages was of particular interest as the Caucasian and Indo-European languages usually have different question-answering systems, but Georgian (Caucasian) and Polish (Indo-European) in fact share the same system. The Armenian language is Indo-European, but the country is situated in the southern Caucasus, on Georgia's southern border, making it worth analysing Armenian in comparison with Georgian (from the point of view of language interference) and with Polish (as two relative languages). The group identified two different deep structures, tracing the occurrence of these in different languages, and showed that one is more natural in the majority of languages. They found no correspondence between relative languages and their question-answer systems and demonstrated that languages in the same typological class may show different systems, as with Georgian and the North Caucasian languages. It became clear that Georgian, Armenian and Polish all have an agree/disagree question-answering system defined by the same deep structure. From this they conclude that the lingual mentalities of Georgians, Armenians and Poles are more oriented to the communicative act. At the same time the Yes/No system, in which a positive particle stands for a positive answer and a negative particle for a negative answer, also functions in these languages, indicating that the second deep structure identified also functions alongside the first.

Questions of Life and Death

The research started with a definition of the general ethical background to be applied in bioethical discussions, particularly regarding aspects of morality that have to be enforced by the community. Only those moral beliefs that can be accepted by consensus in a free discussion can be enforced. It follows that the basic principle of a well ordered society is the equality (and possible upwards extension) of the basic liberties. Therefore, whenever it is possible to respect the principle of autonomy in matters of bioethics (here including questions of abortion, assisted procreation, genetics, organ transplantation and euthanasia) this must be done. On the other hand, there are some common values that can be defended in a free dialogue, values that are needed in order to guarantee stable cooperation in a political society. These values include the respect for human life, which implies the respect for human life in all its forms. This leads to the conclusion that people who are able to be part of the system of cooperation in a political society have rights which are dominant in moral considerations. In all cases where there is no conflict between these rights and the value of life as manifested in human individuals who are not able participate in social cooperation, considerations of the value of the life of the latter must be an important moral consideration. This implies that embryo experimentation should be permitted in order to develop scientific advances needed to save human life, but embryos must not be used for trivial reasons or for the cosmetic industry.

A Computational Model for Processing Lexical Information"

The group analysed some syntactic and phonological phenomena that presuppose the existence of interrelated components within the lexicon, which motivate the assumption that there are some sublexicons within the global lexicon of a speaker. This result is confirmed by experimental findings in neurolinguistics. Hungarian speaking agrammatic aphasics were tested in several ways, the results showing that the sublexicon of closed-class lexical items provides a highly automated complex device for processing surface sentence structure. Analysing Hungarian ellipsis data from a semantic-syntactic aspect, the group established that the lexicon is best conceived of being as split into at least two main sublexicons: the store of semantic-syntactic feature bundles and a separate store of sound forms. On this basis they proposed a format for representing open-class lexical items whose meanings are connected via certain semantic relations. They also proposed a new classification of verbs to account for the contribution of the aspectual reading of the sentence depending on the referential type of the argument, and a new account of the syntactic and semantic behaviour of aspectual prefixes. The partitioned sets of lexical items are sublexicons on phonological grounds. These sublexicons differ in terms of phonotactic grammaticality. The degrees of phonotactic grammaticality are tied up with the problem of psychological reality, of how many degrees of this native speakers are sensitive to. The group developed a hierarchical construction network as an extension of the original General Inheritance Network formalism and this framework was then used as a platform for the implementation of the grammar fragments.

Industrial Restructuring in the Budapest agglomeration

The major 'motor' of the recent Hungarian industrial development has been foreign direct investment, particularly by multinational companies. This has stimulated the development process, as shown by the dynamism of production, exports and profitability of industry in Budapest. On the other hand, this has also led to a split of the industrial sphere into its foreign and domestic sections, or into foreign-owned companies and domestic SMEs. The major question asked in this project is where is Hungarian industry heading and will the gap between the contracting domestic part and the foreign multinationals continue to widen or will they be joined in a much more favourable scenario. Barta sees this as a question of whether Hungary can avoid the 'dead-end street' of South Asian industrialising countries, and instead move towards a new Eastern European or Hungarian model. He concludes that Budapest industry does not follow any given model and indeed its development probably cannot be seen as a 'model' proper in itself, but is, or will be, a mixture of different elements. This would be a welcome fusion of Hungary's rich human resources of accumulated knowledge with foreign direct investment. Budapest would play an exceptional role in such a process, as the gateway for foreign output to the rest of the country. The share of industry in the Budapest economy will continue to decrease, but it will become a more modern and profitable sector. It will also fulfil a technological transfer role between the developed world and the Hungarian countryside (or even a larger region of central and eastern Europe). Barta predicts that Budapest industry will develop a special structure, with a large subcontractor network supporting the large foreign enterprises, and alongside this industrial districts formed by SMEs.

The Work and Workshop of the Master of the Rajhrad Altarpiece

The main aim of this project was to verify the possibility raised in the publication of new archival data in 1980 that the group of panel paintings attributed to the Master of the Rajhrad Altarpiece and his workshop were not created before 1420, as earlier academic opinion held, but in fact only around 1450. It included a detailed analysis of the 21 panels forming the group, including infrared reflectography research. This helped identify the highly personal underdrawing style of the "Rajhrad Master" as common to all the panels in the group, proving that they really form a coherent whole. Questions of the painter's education and the nature of Bohemian society around 1450 were also considered, as. Bartlova felt these had been neglected in earlier studies. She concludes that the Master studied in Prague in the late 1430s and then continued studying in Vienna and Munich from 1440. The new dating of the group of panels connected with this anonymous master and his workshop throws new light on Bohemian artistic production during the late Hussite period (c.1430-c.1470). It was generally thought that artistic activity moved out of Prague after the outbreak of the Hussite wars in the 1420s, but this research revealed considerable activity there throughout the period. Numerous painters listed in the Book of the Prague Painters' Guild for this period can now be linked with extant panels, although most of these have survived outside Prague, principally in South Bohemia. These findings have broad implications for studies of Bohemian art in this period.

How Do We Teach Economics?

The teaching of economics in Hungary has changed fundamentally since the 1980s for two main reasons. Firstly, the transformation towards a market economy has changed the needs of students, and secondly, there has been a move to harmonise Hungarian methods of teaching with Western ones. The number of institutions involved in economics education has increased substantially to meet new demand and these institutions offer a wide range of programs, though the topics covered tend to be more practically based than previously. A survey of students set out to evaluate economics as a profession by investigating social esteem, financial compensation, career prospects, and mobility within the profession. Amongst full-time students there was a strong correlation between the parents' background and the students' career prospects. Full-time students were more optimistic than part-time students, although the latter had a higher opinion of the academic level of their educational establishments. A second survey, this time of economics teachers, revealed the disturbing fact that teachers rated themselves in the last but one position according to social esteem and felt that society had a poor opinion of them. Fifty percent expressed a desire to leave the profession and 70% supplemented their income with work outside their school, rarely within the domain of economics. The final part of the research analysed the situation in private educational institutions, nothing that unemployment retraining grants offered by the Ministry of Labour have created an incentive for private entrepreneurs to organise courses and that the quality of these courses varies considerably.

The Role of Gender in Ethnic Perception

A group of 406 Polish university students (210 women and 196 men) were asked to describe typical representatives of selected ethnic groups and their typical female and male members. The descriptions were based on a list of 24 traits and a list of 18 values, accompanied by scales for measuring trait-typicality and value-importance. The participants' level of confidence about the accuracy of the descriptions, their ethnic attitudes and their perception of the relative social status of men and women in ethnic groups were also measured. The results indicate an effect of masculinisation of ethnic images for both traits and values. Descriptions of typical representatives of ethnic groups resemble the images of typical men significantly more than those of typical women of these nationalities, even for the most modern nations. Differences registered between images of typical representatives of ethnic groups and their male and female members concerned primarily the traits and values basic to gender stereotypes. The images of women were significantly more favourable than those of men. The bias in ethnic perception towards the gender of the stereotype-holder was also indicated. Several differences were found between women's and men's perception of typical representatives of ethnic groups and especially of ethnic gender subgroups, without however the predicted effect of gender in-group favouritism. There was also a degree of ethnic in-group favouritism of Poles related to the gender both of participants and of the ethnic target groups.

The Process and Factors of Language Shift and Maintenance: Sociolinguistic Research into the Romanian Minority Community in Hungary

This study of the process of language shift and maintenance in the bilingual community of Romanians living in Hungary was based on 40 tape-recorded Romanian sociolinguistic interviews. These were transcribed into computerised form and provide an excellent source of sociolinguistic, contact linguistic and discourse analysis data, making it possible to show the effect of internal and external factors on the bilingual speech mode. The main topics considered were the choice of Romanian and Hungarian in community interactions, factors of language choice, code-switching: introlanguage and interlanguage, reasons for code-switching, the relationship between age and the frequency of code switching in the interview situation, and the unequal competition of minority and majority languages at school.

Comparative Analysis of Russian and French Prosodies: Theoretical, Experimental and Applied Aspects"

Experience shows that in teaching the pronunciation of a foreign language, it is the native syllable stereotype that resists correction most strongly. This is because the syllable is the basic unit of the perception and production of speech, and syllabic production is highly automatic and to some degree determines the prosody of speech at all levels: accent, rhythm, phrase, etc. The results of psycho-physiological studies show that the human acoustic analyser is a typical contemplator organ and new acoustic qualities are perceived through their inclusion into the already existing system of values characteristic to the mother tongue. This results in the adaptation of the perception and so production of foreign speech to native patterns. The less conscious the perception of the unit and the more 'primitive' its status, the greater the degree of its auditory assimilation, and the syllable is certainly among the less controllable linguistic units. The group carried out a complex investigation of the French and Russian languages at the level of syllable realisation, focusing on the stressed syllable of both open and closed types. The useful acoustic characteristics of the French/Russian syllable pattern were determined through identifying a typical syllable pattern within the system of each of the two languages, comparing these patterns to establish their contrasting features, and observing and systematising deviations from the pattern typical of the French/Russian language teaching situation. The components of the syllable pattern shown to need particular attention in teaching French pronunciation to Russian native speakers were intensity, fundamental frequency, and duration. The group then developed a method of correction which combines the auditory and visual canals of sound signal perception and tested this method with groups of Russian students of different levels.

Resocialisation of Disabled Veterans in Former Yugoslavia

The team examined 147 amputated war veterans in the former Yugoslavia between February and December 1998. The official end of the war, substitution of lost body parts and adjustment to the new state of physical disability added extra tasks to these people's efforts to rejoin "normal life". The resocialisation process of amputated persons, i.e. the process of their return into the social environment with the related readjustment and establishment, was observed through its objective and subjective indicators. In addition to obtaining information about socio-demographic characteristics and current working status, the group focused on the psychological dimension, i.e. the individual reality of the disabled persons. In this sense they began with research into the personal, social and professional identity (how they see themselves under these altered circumstances and how they determine their place in the world). To do so they used the model of basic personality supports and observed the resocialisation according to the psychological support systems. They therefore focused on the following topics: body, social identity and belonging, personal identity, working status and engagement, individual responsibility and expectations from the social environment, and orientation towards the future. These were considered with respect to certain significant socio-demographic characteristics of the interviewees. The data were gathered through standardised interviews. Bearing in mind the unpopularity of this subject among experts in the country and the lack of material in specialist literature, the group chose to use descriptive research logic in order to "record" the situation in this field and to establish a framework for future studies which may be methodologically and statistically more complex and thematically more focused.
