The concept of masculinity in Freud's theory of culture
TomiZorica
Theoria, Beograd , 2009, DOI: 10.2298/theo0901077t
Abstract: This paper stresses out the concept of 'masculinity', as the functional for Freud's theory of culture. The traditional dichotomy between the nature and the culture, which is based upon the difference between femininity and masculinity, is used in Freud's work as the fact that confirms the 'origin of culture' as the masculine enterprise. Focused on Freud's theory of instincts this paper shows off that this theory interprets man as the only possible subject of culture.

Krnjaja Vesna,Levi? Jelena,Ivanovi? M.,TomiZorica P.
Zbornik Matice Srpske za Prirodne Nauke , 2005, DOI: 10.2298/zmspn0508167k
Abstract: In in vitro conditions, virulence of 91 isolates of species Fusarium genus (F. oxysporum, F. solani, F. acuminatum, F. equiseti, F. arthrosporioides, F. prolifera- tum, F. avenaceum, F. semitectum, F. tricinctum, F. sporotrichioides and F. graminearum) towards alfalfa seedlings was investigated. Isolates of investigated species originated from diseased alfalfa plants collected at four locations in Serbia based on symptoms of wilting caused by Fusarium and root rotting. Pathogenicity and virulence of investigated isolates of Fusarium spp. were determined by visual evaluation of inoculated seedlings of cultivar K28 in laboratory conditions. All isolated of investigated species had pathogenic effect on alfalfa seedlings which expressed symptoms such as necrosis of root, moist rotting and "melting of seedlings". Colour of necrotic root tissue varied from light brown, brown lipstick red to explicit black, depending on the Fusarium species. Strong virulence was established in 48 isolates, medium virulence in 31 and weak virulence in 12 isolates.

Archives of Biological Sciences , 2010, DOI: 10.2298/abs1002363t
Abstract: The floristic composition of meadow associations within the fenced areas of forest hunting grounds was investigated in the spring of 2008 at three sites: Karaku a (Srem), Milo eva voda (Mt. Sokolovica) and Lomni ka reka (Mt. Veliki Jastrebac), Serbia. At the first location three associations were determined (Agrostio-Juncetum effusi Cinc.1959., Trifolio-Agrostietum stoloniferae L. Mark.1973., and Agrostietum vulgaris. Z. Pavl. 1955 sensu lato.); at the second location Festuco-Agrostietum Horv. (1952) 1982. em Trinajest. 1972., and at the third location Agrostio-Festucetum valesiacae Gaji 1961. Hemicryptophytes were the dominant life form in all the sites (ranging from 61.1 to 72.9%). Also, the presence of 24 floral elements was recorded. The largest number of floral elements was determined at the site of Mt. Sokolovica (17), and the lowest at the third site, Mt. Veliki Jastrebac (9).

Zbornik Matice Srpske za Prirodne Nauke , 2007, DOI: 10.2298/zmspn0713103k
Abstract: Pathogenicity of 10 Fusarium verticillioides isolates, originated from grain of wheat (five isolates) and maize (five isolates), were studied under greenhouse conditions. Based on different parameters of the pathogenicity estimate (a scale for % of nonemerged plants, % of survived plants, plant vigour - the growth and dry weight of roots and epicotyls and disease severity) it was determined that all F. verticillioides isolates expressed a different degree of pathogenicity. According to % of nonemerged plants six three and one F. verticillioides isolates expressed low, moderate and high degree of pathogenicity, respectively. All F. verticillioides isolates reduced the plant survival rate and vigour, while the disease severity ranged from 2.0 to 3.54. Two types of nit mutants, nit1 and NitM, were obtained by the use of the method of vegetative compatibility. The frequency of nit1 mutants was greater (58.79%) than the frequency of NitM mutants (5.77%). A total of 10 vegetative compatibility groups (VCGs) of F. verticillioides were established in the complementation tests. These results point out to a high genetic diversity of F. verticillioides population.
Modification of smectite structure by sulfuric acid and characteristics of the modified smectite
TomiZorica P.,Anti?-Mladenovi? Svetlana B.,Babi? Biljana M.,Poharc-Logar Vesna A.
Journal of Agricultural Sciences , 2011, DOI: 10.2298/jas1101025t
Abstract: Bentonite samples from Petrovac and Aleksinac were treated with sulfuric acid of different molarities. Differences in structure and texture of the initial and modified bentonite were determined by chemical analysis and Xraypowder diffraction (XRPD), infra-red spectroscopy (FTIR), scanning electron microscopy (SEM) and physisorption nitrogen at 196°C. Sulfuric acid caused an exchange of Al3+, Fe3+ and Mg2+ with H+ ions which led to a modification of the smectite crystalline structure. The Mg and Fe substitution in the octahedral sheet promoted the dispersion of those layers and forming of amorphous silicon. The sequence according to which the cations left the octahedral sheets was as follows: Mg2+>Fe3+>Al3+. The sulfuric acid activated bentonites exhibiting a lower cation exchange capacity (CEC) and а change of specific surface area (SBET) from 6 to 387 for bentonite from Petrovac and from 44 to 1784 m2 g-1 for bentonite from Aleksinac, positioning them as an excellent absorber in wine technology and in the protection of soil and environment.
Misperceptions of peer gambling norms among adolescents: Analysis of a national sample in Finland  [PDF]
Susanna Raisamo, Tomi Lintonen
Open Journal of Preventive Medicine (OJPM) , 2012, DOI: 10.4236/ojpm.2012.22019
Abstract: Introduction: Misperceptions of peer drinking norms are widely documented in the US student populations and are associated with increased personal consumption. Few studies have examined misperceptions of peer gambling, and none of these have been conducted among adolescents in the European context. In a national sample, we examined misperceptions of peer gambling in Finland. Tenets of the social norms approach form a framework for discussion of the findings. Methods: Participants were 4526 adolescents aged 12 to 18 years who completed the nationwide Adolescent Health and Lifestyle Survey in 2011. Main measures were gambling behavior and the perception of same age-sex peers’ gambling. Misperception was an overestimation of the frequency of gambling by others compared to the actual frequency of gambling. Results: Adolescents held substantial misperceptions of peer gambling, imagining they gambled much more than they actually did. Age, sex, and gambling behavior were correlated with the perceptions. The extent of misperception was greatest among monthly gamblers, whereas non-gamblers and daily gamblers were more accurate in their perceptions. Estimations of peers’ gambling frequency were more accurate in boys than in girls and among those aged 12 years than among older adolescents. Conclusion: Our findings suggest that adolescent gambling prevention efforts could benefit from adopting a social norms approach; that is, correcting gambling-related misperceptions might discourage gambling and protect adolescents from adopting more severe gambling patterns.
Mobile Findex: Facilitating Information Access in Mobile Web Search with Automatic Result Clustering
Tomi Heimonen
Advances in Human-Computer Interaction , 2008, DOI: 10.1155/2008/680640
Abstract: Designing an effective mobile search user interface is challenging, as interacting with the results is often complicated by the lack of available screen space and limited interaction methods. We present Mobile Findex, a mobile search user interface that uses automatically computed result clusters to provide the user with an overview of the result set. In addition, it utilizes a focus-plus-context result list presentation combined with an intuitive browsing method to aid the user in the evaluation of results. A user study with 16 participants was carried out to evaluate Mobile Findex. Subjective evaluations show that Mobile Findex was clearly preferred by the participants over the traditional ranked result list in terms of ease of finding relevant results, suitability to tasks, and perceived efficiency. While the use of categories resulted in a lower rate of nonrelevant result selections and better precision in some tasks, an overall significant difference in search performance was not observed.

Tomi? Zagorka
Glasnik ?umarskog Fakulteta , 2006, DOI: 10.2298/gsf0694029t
Abstract: The syntaxonomic differentiation and nomenclature of beech forests in Serbia is analyzed. Based on 75 phytocoenological tables of numerous authors and this author’s, from different parts of Serbia, 7 synthetic tables were constructed, one for each of the suballiances in the alliance Fagion moesiacae Ble i et Laku i 1970. By the introduction of the unique criteria of International Phytosociological Nomenclature only 20 basic syntaxonomic categories (associations) were formed and denominated, distributed into 7 suballiances. In this way, the nomenclature and classification of beech forests in Serbia has been harmonized with the international standards.
