Published: August 2020

Bovine pregnancy diagnosis (PD) by transrectal palpation (TRP) is an important skill for veterinary graduates. Factors influencing students’ PD accuracy were investigated to optimize bovine PD by TRP training without increasing live animal exposure. The objective was to determine whether arm length and strength, proprioception, and exposure to a 6-week exercise training program were significantly associated with students’ PD accuracy. Veterinary students ( n = 128) who had previously received formal theoretical and practical training in bovine TRP and PD (live cows and TRP simulators) were assessed for PD accuracy on live cows. Prior to assessment, arm muscle strength measurement, an exercise program, and additional TRP sessions on Breed’n Betsy® simulators and live cows were offered to the students. Seventy-eight students volunteered to participate in the arm length measurement, muscle strength, and proprioception testing. Of these, 35 randomly allocated students completed a 6-week exercise program, after which muscle strength was reassessed. Each student performed PDs on six cows of which the pregnancy status, ranging from 6 weeks to 9 months pregnant or not pregnant, was predetermined by an experienced veterinarian. PD accuracy was measured as sensitivity and specificity, being defined as the proportion of pregnant or nonpregnant cows, respectively, correctly identified by the student. It is concluded that hand grip strength and participation in an exercise program are significant predictors of veterinary students’ PD accuracy. Implementation of an exercise program aimed at improving grip strength in the veterinary curriculum is a novel approach to improve bovine TRP and PD training.

Authors: Barbosa Emerson Silva
Published: August 2020

O presente artigo tem por objetivo descrever e discutir as práticas de mediação de conflitos realizadas pelas Polícias Civis, a partir de dois projetos em desenvolvimento: uma já iniciado e em fase de consolidação, que é o projeto dos Núcleos Especiais Criminais da Polícia Civil de São Paulo; e outro, o projeto dos Núcleos de Polícia Judiciária Restaurativa da Polícia Civil do Distrito Federal. Trata-se, consoante se observará no trabalho, de uma tentativa das instituições policiais de substituir práticas tradicionais de investigação e imputação de culpa por práticas de negociação e conciliação de conflitos. Por meio da revisão de literatura e de entrevistas realizadas com os participantes do projeto na PCDF, pretende-se identificar e analisar possíveis vantagens e riscos que referido projeto pode enfrentar, bem como caracterizar a percepção dos envolvidos sobre a necessidade de modificar a forma como as policiais lidam com alguns tipos de conflitos.

A reinvenção das Maculaturas realizadas por Lotus Lobo
Authors: Firme Braga Nara
Published: August 2020

Neste artigo, apresentarei “As Maculaturas” da artista mineira Lotus Lobo. Maculatura era o nome dado, no passado, às chapas de folha de flandres, utilizadas tanto para teste como para acerto de impressões de embalagens de produtos nas casas de impressão comercial em litografia. Essas chapas recebiam várias impressões de diversas marcas, causando um emaranhado de imagens superpostas. A partir do estudo de Hans Belting, conhecido como “A Arqueologia da Técnica”, avaliarei como Lotus, ao apropriar-se das Maculaturas e da litografia (evidenciando novamente esta velha técnica de impressão), transforma a própria litografia em arte. Analisarei, a partir das reflexões de Roland Barthes e Maria do Carmo de Freitas Veneroso, o caráter intertextual das Maculaturas, explorando as relações existentes entre palavra e imagem, a partir da “textura gráfica”. Por fim, relacionarei as Maculaturas de Lotus Lobo com o trabalho do artista americano Robert Rauschenberg, com Décollage do artista italiano Mimmo Rotella e com as escrituras ancestrais dos palimpsestos.
O livro tem volume?
Authors: Rodrigues Belo Diego
Published: August 2020

Um fragmento de silêncio que ocupa as mãos e os olhos. O livro impresso convida não só a uma leitura silenciosa, bem como clama por um ambiente de escassos ruídos. Atividade íntima, exige concentração e dedicação do corpo-leitor. O projeto gráfico pode ser visto como estrutura pensante e de pensamento, favorece a circulação das ideias e serve como instrumento para a organização, consolidação e disseminação do conhecimento. Cumulativo, irreversível, sucessivo e cronológico, o saber configurado nos impressos se deve também a certa reverência e autoridade que conferimos a eles. É na comunhão provocada pelo ato de leitura que o livro pode ser tomado enquanto meio decisivo para o fomento das faculdades perceptivas e do pensamento. A partir deste artigo cada vez mais escasso na sociedade contemporânea – o silêncio – convoco Didi-Huberman para tratar sobre a complexa noção de “sintoma”, seja em suas configurações visuais ou temporalidades. Proponho uma ideia de silêncio enquanto potencial sintoma do livro, instigando sua visualidade por meio de um sinal tipográfico – a “vírgula de perquirição”. Com isso, objetivo examinar o inquietante “silêncio do livro” em relação à capacidade projetual do design gráfico construir espaços convenientes para ativar a imaginação e ação humanas.
A força da gravidade e a origem do movimento
Authors: Crêspo Fernando
Published: August 2020

No centro da ação performativa, vamos encontrar a relação que o corpo estabelece com a força da gravidade. A resistência ou entrega a esta força, a exploração do seu poder sobre o movimento e a presença da ilusão gravitacional noutras produções artísticas multidisciplinares, justificam este estudo. Aprofundam-se os momentos em que o corpo se ergue, movimenta ou é capaz de se orientar, precisamente, quando se opõe à força da gravidade, quando negoceia com esta ou quando se proprioceciona. Na variedade de superfícies de suporte – às qual o corpo se apoia, agarra, pendura, salta e desliza – encontra-se um potencial criativo que resulta da relação de resistência à força da gravidade que o corpo estabelece, num determinado momento, com estas mesmas superfícies. Apresentam-se, também, meios circundantes que transformam, de forma radical, o movimento e sua relação com a gravidade. Por fim, retorna-se ao corpo, ao centro do corpo, para aí encontrar o impulso primordial do movimento.

Authors: Faizi Waqar Un Nisa , Shakil Anila Fatima , Bibi Wilayat
Published: August 2020

Employee associations serve as resources of interested employees in helping the advisory committees and the staff task forces. Besides, they may also help in publicizing information of interest, procedures, and policy to employees and participate actively in the process of academic review. In universities, a significant role is played by employees unions. Unlike Employee unions, the existence of employee associations differs a lot. Many benefits can be gained from the relationship between the management of the University and employee association. It has been found that in the past, universities in Pakistan have failed to revive and engage with their employees, due to which effectiveness was lost majorly by the associations present in the universities. This research paper will critically reflect upon the relationship between the employee association and the overall management of the universities of Peshawar. Further, it will also identify the significant barriers and issues faced by the employees associations.
Metonymy in Sasha Cherny and Vladimir Vysotsky’s Poetry
Authors: Petrova O.O.
Published: August 2020

The article deals with the description of lexical metonymy in Sasha Cherny and Vladimir Vysotsky’s poetry. The author notes the most frequent models of the metonymic transfer of meanings characteristic of the works of both poets, illustrating them with numerous examples from the texts. The article identifies models of substantive, adjective and verbal metonymy. The author emphasizes that in Sasha Cherny’s poems substantive metonymy prevails. Adjective and verbal metonymic transfers of meanings are less represented. Specific features of metonymy in Vladimir Vysotsky’s poetry are noted. Characteristic features of V. Vysotsky’s poems are such linguistic phenomena as metonymic concretization and generalization, an abundance of verbal metonymic hyphenation, as well as inverse actant metonymy in nouns. The observations made by the author can be useful for both linguists and philologist experts in literature.
Vocabulary and in the Semantics of Zoonyms Correlation of Connotative and Denotative Components in the Semantics of Some Groups of Abstract (On the Example of the Word “Cow”)
Authors: Krasilnikova P.Yu.
Published: August 2020

In linguistics, there are different ideas about the ratio of the denotative and connotative sides of the meaning of a word. Despite the fact that additional contextual semantics, as a rule, has a larger information volume, connotative meanings are invariably perceived as secondary to denotative ones. Obviously, there is a pattern linking denotation with the connotation formed on its basis. The article considers the difference in connotations of quite distant from each other in terms of the degree of concreteness of words — nominal vocabulary denoting abstract concepts, and specific nouns of the thematic group of zoonyms. The result of the comparison is the conclusion about the correspondence of the volume of connotation and denotation as an inversely proportional dependence: the narrower the area of denotation, the greater the qualitative and quantitative potential of the word to develop connotative meaning, and vice versa — the more magnificent the bouquet of semantic elements associated with emotions, ratings, and ideas about the non-material side of the world, the less the lexeme has opportunities for the formation of additional values outside certain secondary modeling systems.
The Modelling of Creative Artistic Personality Based on the Love Songs Made on A.S. Pushkin’s Poem “The Beauty, Don’t Sing in My Presence…”
Authors: Antipina E.S. , Prokhorenkova S.A.
Published: August 2020

The article updates the role of interdisciplinary approach in linguistics, and considers the possibilities of using musicological analysis in multi-paradigmatic modelling of a creative linguistic personality. In the semiotic triad music — language — personality the peculiarities of artistic world-view of homo scribens (the man who writes) are analyzed. The love songs of Great Russian composers made on A.S. Pushkin’s poem “The beauty, don’t sing in my presence” are taken as an example. The similar tendencies in the semantic organization of the material structure in music and poetic works are justified, and semantic dominants of “oriental” love songs are defined. Keywords and general patterns in the interpretation of cultural constants concepts that translate the national picture of the world are revealed. The hypothesis is proved that musicological analysis has great potential in the process of representing the linguistic picture of the world not only of the creator of music (composer), but also of the author of the text (poet).

Effect of Mutilation and Ablation to Molting of Mangrove Crab (Scylla serrata) as Soft Crab          Soft crabs that are more expensive than regular crab, that having hard carapace, in nature and in culture are very difficult to find. This study aimed to get the soft crabs more easily controlled the number  of molting in culture, by the method of mutilation and ablation. Thus the supply in market will be able to meet existing demand. Four treatment techniques had been implemented namely mutilation, ablation, ablation + mutilation, and controls which each performed four replications. Complete Randomized Desaign (CRD) was used because the experiment was conducted in a fairly homogeneous patch of tambak pond. Experimental unit in the form of bamboo pen cages with the size of 2x1x1m filled with 20 crabs.  All experimental crabs were ready for molting (dark color) even with 40-90 g of varied sizes. The results showed that each week until the third week, the average number of crabs per unit experiment with techniques of mutilation was always having highest of molting number, respectively 1.00, 3.25, and 11.00 crabs and having the lowest mortality rate, respectively  0. 25, 1.75, and 1.25 crabs, compared with the ablation, mutilations + ablation technique, and control. Statistically  four treatments in molting, in week two and  three was significantly different , eventhough in mortality was not (α = 5%).Keywords : mangrove crab (Scilla serrata), soft crabs, mutilation, ablation ABSTRAK                Kepiting lunak yang  harganya lebih mahal dari kepiting biasa bercangkang keras, di alam maupun dalam budidaya sangat susah ditemukan.  Penelitian ini bertujuan untuk mendapatkan kepiting lunak yang lebih mudah terkontrol jumlahnya dalam budidaya, dengan metoda mutilasi dan ablasi.  Dengan demikian dalam  pasar ketersediaannya akan dapat memenuhi permintaan yang ada. Empat perlakuan telah dilaksanakan yaitu teknik mutilasi, ablasi, mutilasi+ablasi, dan kontrol dengan masing-masing dilakukan empat kali ulangan.

Efficacy of jackfruit wood destilate (Artocarpus integra Merr.) against dry-wood termites (Cryptotermes cynocephalus Light)          Wood is organic material that is susceptible to dry wood termite attack Cryptotermes cynocephalus Light. To protect it from the attack, the wood is commonly preserved with chemicals. The chemicals preservative is not eco-friendly material. In order to explore the alternatives of preservatives, distillate extracted from jack fruit (Artocarpus integra Merr.) wood was tested against the termite. The research aimed to examine the effectiveness of distillate against termite in term of retention, termite mortality and protection degree parameter. Sample test is rubber (Hevea brasiliensis Muell.Arg.) wood with dimension 5 cm x 2,5 cm x 2 cm. Samples were soaked into distillate according to concentration i.e. 5%; 15%; 45% and 65% for 2 and 5 days. Experiment was designed with complete random design with 4 replications. The research showed that retention and termite mortality were positively correlated with distillate concentration whereas soak duration influenced retention. Protection degree did not differ from control. We conclude various distillate concentration influenced retention and termite mortality but not protection degree of wood.Key words: mortality, protection degree, retentionABSTRAK         Kayu merupakan bahan organik yang mudah diserang oleh rayap kayu kering Cryptotermes cynocephalus Light. Untuk melindungi kayu dari serangan rayap tersebut biasanya kayu diawetkan dengan menggunakan bahan kimia sintetik. Bahan pengawet kayu termasuk bahan kimia yang tidak ramah lingkungan. Dalam rangka mencari alternatif bahan pengawet kayu ramah lingkungan, maka dicoba destilat kayu nangka (Artocarpus integra Merr.). Penelitian ini bertujuan untuk mengetahui efektivitas destilat kayu nangka terhadap retensi, mortalitas dan derajat proteksi dari serangan rayap kayu kering C. cynocephalus. Contoh uji yang digunakan adalah kayu karet (Hevea brasiliensis Muell.Arg.) dengan ukuran 5 cm x 2,5 cm x 2 cm yang direndam dalam cairan destilat kayu nangka dengan konsentrasi 5%; 15%; 45% dan 65% selama 2 dan 5 hari. Di samping itu disediakan contoh uji kontrol. Percobaan menggunakan Rancangan Acak Lengkap faktorial dengan 4 ulangan. Parameter yang diukur adalah retensi, mortalitas rayap kayu kering dan derajat proteksi. Hasil penelitian menunjukkan bahwa nilai retensi dan mortalitas meningkat sesuai dengan peningkatan konsentrasi. Sedangkan lama perendaman hanya berpengaruh terhadap retensi. Derajat proteksi tidak berbeda nyata antara perlakuan dengan kontrol. Kesimpulannya adalah perbedaan konsentrasi destilat hanya berpengaruh terhadap retensi dan mortalitas rayap kayu kering tetapi tidak terhadap derajat proteksi.    Kata kunci: Derajat proteksi, retensi, mortalitas
