An Independent Evaluation of the Reliability of the Implied Private Company Pricing Line Model in Appraisal Practice
Authors: Dawson Peter C.
Published: June 2016

The Implied Private Company Pricing Line (IPCPL) model is intended to calculate a reliable present value discount rate for a 100 % control interest in a private/closely-held operating company under the Fair Market Value Standard. But, would its application be more reliable than the Adjusted Capital Asset Pricing Model (ACAPM) or Build-Up Method (BUM)? This article evaluates two core aspects of the model’s practical application that have received little attention in the literature: (1) Does it eliminate a significant portion of subjective adjustments? The private company market’s adjustment for key marketability differences is said to be built into the private company transaction prices, eliminating the need for an appraiser to subjectively quantify and apply those adjustments; and (2) Being “actual market clearing prices”, do the private company transaction prices reflect Fair Market Value?
Discriminating between (in)valid External Instruments and (in)valid Exclusion Restrictions
Authors: Kiviet Jan F.
Published: June 2016

In models estimated by (generalized) method of moments a test on coefficient restrictions can either be based on a Wald statistic or on the difference between evaluated criterion functions. From their correspondence it easily follows that the statistic used for testing instrument validity, the Sargan-Hansen overidentifying restrictions (OR) statistic, is equivalent to an exclusion restrictions test statistic for a nonunique group of regressor variables. We prove that asymptotically this is the case too for incremental OR tests. However, we also demonstrate that, despite this equivalence of test statistics, one can nevertheless distinguish between either the (in)validity of some additional instruments or the (un)tenability of particular exclusion restrictions. This, however, requires to be explicit about the adopted maintained hypothesis. It also highlights that recent warnings in the literature that overidentifying restrictions tests may mislead practitioners should not be directed towards the test, but to practitioners who do not realize that inference based on such tests is unavoidably conditional on the validity of particular just-identifying statistically untestable assumptions.
The Role of National Cultures in Foreign Subsidiaries’ Practices Applied to Support Knowledge Flow within MNCs
Authors: Purgał-Popiela Joanna
Published: June 2016

The main goal of this paper is to contribute to a better understanding of intercultural aspects affecting cross-border knowledge flow in MNCs by recognizing similarities and differences pertaining to the practices supporting such flow in 200 Polish-based subsidiaries grouped into clusters according to ‘national’ origin of parent-company2. Analyses of data collected in 2014 encompassed descriptive statistics, and in-pair comparisons. Significant differences were identified by a Kruskall-Wallis test, Chi- Square Test, and a UMW test. Results suggest that such a flow was supported mainly by discussions via ICT and access to databases. Significant differences between clusters were found for usage of e-learning programs, e-mentoring/e-coaching, virtual teams, and HRM practices.
Cultural and Religious Factors Versus Success in Business
Authors: Masiukiewicz Piotr
Published: June 2016

Cultural and religious factors do have some connection with results achieved in business; it is particularly well visible on the financial market. The paper presented possibilities of researching connections between cultural and religious factors and success in business, based on selected measures. Analysis covers three areas: top managers’ incomes, effectiveness measured by return on capital, risk appetite of financial institutions with international capital and international board of managers. Indicators of correlations and comparison of measures used for analysis confirm inter-relationships of cultural and religious factors and success in business.
To Work or Not to Work… in a Multicultural Team?
Authors: Stankiewicz Katarzyna , Ziemiański Paweł
Published: June 2016

The main goal of the article is to present research findings regarding student’s attitude to working in a multicultural team (MCT). Research participants of different cultural background completed the research survey. Their willingness to work in MCT was measured together with factors that influence it. These include factors related to both team members and the task structure.

Research findings indicate that the respondents preferred to work in MCT if the task required diversity of cognitive perspectives, e.g. in a situation requiring creative or out-of-the-box thinking. In contrast, the strongest preference for working in a single-culture team (SCT) was present in the case of tasks requiring mutual understanding among the team members and like-mindedness. In addition, it was found that the preference to work in SCT or MCT entrusted with a task with specific requirements was also related to the experience in working in such teams declared by the respondents.

Conclusions and recommendations may be utilized to design methods for managerial education and training.
Influence of selected Rhizoctonia solani isolates on sugar beet seedlings
Authors: Skonieczek Paweł , Nowakowski Mirosław , Piszczek Jacek , Żurek Marcin , Matyka Łukasz
Published: June 2016

From 2008 to 2010 the levels of sugar beet seedlings infection caused by Rhizoctonia solani were compared in laboratory tests. Seven sugar beet lines were tested: H56, H66, S2, S3, S4, S5 and S6 as well as three control cultivars: Carlos, Esperanza and Janosik. Sugar beet lines with tolerance to rhizoctoniosis and cultivars without tolerance were infected artificially by R. solani isolates: R1, R28a and R28b. These isolates belong to the second anastomosis group (AG), which is usually highly pathogenic to beet roots. The aim of the experiment was to test whether the tolerance of sugar beet genotypes to R. solani AG 2 prevents both root rot, and damping-off of seedlings, induced by the pathogen. Sugar beet lines tolerant to brown root rot in laboratory tests were significantly less sensitive to infection of the seedlings by R. solani AG 2 isolates in comparison to control cultivars. Rhizoctonia solani AG 2 isolates demonstrated considerable differences in pathogenicity against seedlings of sugar beet lines and cultivars. The strongest infection of sugar beet seedlings occurred with the isolate R28b. The greatest tolerance to infection by AG 2 isolates was found for the S5 and S3 breeding lines.
Steven Cheung at Chicago, 1968
Authors: McCloskey Deidre N.
Published: June 2016

I met Steve in August 1968 when he and I were assigned as office mates in the old Social Science Building of the University of Chicago. Steve was visiting Chicago, finishing up his book on sharecropping – we had many talks about it – and I was just starting as an assistant professor. Of course I learned in the first half hour of our friendship that Steve was a star in photography, in kite flying, in ping pong, and in Chinese checkers…and economics! Well, he was – I can testify to the economics and the photography (he once told me that he thought in English as an economist but in Chinese as a photographer); and I did once catch sight of him playing a mean game of ping pong. I was dazzled by the Famous Chicago Department, but Steve got me going in a slightly different – and very UCLA – direction, leading me to work on enclosures and open fields in England.
The Affective Politics of the Precariat: Reconsidering Alternative Histories of Grassroots Worker Organising
Authors: Chun Jennifer Jihye
Published: June 2016

This article engages with Guy Standing’s arguments about the affective politics of the precariat by reflecting on the conditions that facilitate, as well as constrain, the solidaristic transformation of the precariat. After evaluating Standing’s Polanyian theory of social change based on assumptions about the destructive tendencies of neo-liberal capitalism and a liberal politics of hope, it offers two critical interventions. First, celebrating the solidaristic traditions of the past industrial era erases historical patterns of labour organising that were quite exclusionary for traditional denizens such as women, non-white immigrants and people of colour in the United States. Second, a top-down approach to solidaristic transformation neglects alternative histories of grassroots worker organising around non-work social identities and communities. This historical erasure and neglect overlooks how oppressed and socially devalued workers have sought to challenge the fundamental gap between reality and rhetoric under liberal capitalist democracy, a key predicament for long-standing members of the precariat that persists in today’s global era of pervasive inequality and precarity.
On Standing's A Precariat Charter: Confronting the Precaritisation of Labour in Brazil and Portugal
Authors: Braga Ruy Gomes
Published: June 2016

Guy Standing’s new book, A Precariat Charter, does not allow us to forget that we live under the shadow of the “precariat” – a group of people who are deprived of any work-related guarantees, subjected to uncertain income, and without a collective identity that is rooted in a labour world. Among the many merits of his most recent book, Standing reports the damaging effects suffered by a substantial section of the European trade union movement. At the root of this decline is labour’s submission to a socially irresponsible and environmentally unsustainable model of development. First, I will examine the book from a Southern perspective. The data and examples that Standing provide pertain largely to changing working-class relations in advanced capitalist countries. In contrast, I will focus my attention on the metamorphosis of the working class in the Global South – particularly Brazil – during the post-Fordist era in order to raise questions about the class character of the precariat.
Precarity North and South: A Southern Critique of Guy Standing
Authors: Scully Ben
Published: June 2016

Guy Standing is among the most provocative and influential analysts of the rise of precarious work around the world. His writing is part of a wave of global labour studies that has documented the spread of precarious work throughout the Global North and South. However, this article argues that by treating precarity around the world as a single phenomenon, produced by globalisation, the work of Standing and others obscures the different and much longer history of precarious work in the Global South. This article shows how many of the features that Standing associates with the contemporary “precariat” have long been widespread among Southern workers. This longer history of precarity has important implications for contemporary debates about a new politics of labour, which is a central focus of Standing’s recent work.

Religious Motifs in the Novel “The Magdeburg Wedding” by Gertrud von le Fort
Authors: Piasta Ewa Anna Anna
Published: June 2016

Gertrud von le Fort, who was born in 1876 in Minden in Westfalen and died in 1971 in Obersdorf, was a German writer, poet and essayist. A number of her works are backgrounded with historical events. The aim, however, is not to evoke concrete events or their historical reconstruction but to show some spiritual problems and the timeless Christian message.The objective of the article is to analyse religious motifs in the novel The Magdeburg Wedding. The religious elements are taken from a concrete aspect of reality, such as liturgy, or wider, i.e., the cult, the Bible and other religious texts or even authentic events from the history of the Church. Those motifs are present in the sphere of style, metaphor, subject matter and the ideological content of the work. The literary genres structurally connected with religious tradition are interwoven in the novel. The function of the Biblical paraphrases is to correct the thoughts or attitudes of the protagonists; they as well act as a determinant of morality. The metaphysical perspective, which is manifested in the novel in a variety of ways, is not only expressed by the elements belonging to the Christian tradition but as well shows the traces of magical thinking.
Homonymy among the Nominates Concerning Time and Space: Polish­ - Russian Contrastive Study
Authors: Król Martyna
Published: June 2016

The article is devoted to the problem of interlanguage homonymy. Resulting from the analysis of Polish and Russian nominates (words and phrasemes) in time and space, there have been selected four groups of interlanguage homonyms: proper homonyms (as well known as the simple ones), homonymoidal homonyms, idiomatic homonyms and culture homonyms.Special attention should be paid to the homonymoidal type of interlanguage homonymy, as this type of homonymy covers the cases of meaning inadequacies of words having very similar meanings in both analysed languages, and in formal-descriptive linguistics, those words are described as ambiguous. The practice in interlanguage contacts shows that the axiom concerning the language polysemy has a very negative influence on the acquisition of the so-called ambiguous lexemes of a foreign language by contributing to the process of identification of a certain form with all the meanings associated with this form in the native language. Hence, here comes to being the postulate to treat lexemes as monosemantic language units and obligatorily use the new notion “homonymoid”, which, according to the author, may replace the notion of “polysemy” as referred to the relations of systemic nominative units.
Polish and Bulgarian Somatic Phrases Justified with the Names of the Parts of the Body Designed for Speaking
Authors: Michow Elżbieta
Published: June 2016

The article includes the analysis of Polish and Bulgarian somatic phrases with the meaning justified with components, i.e., the names of the parts of the body having a semantic feature of mental functions “designed for speaking” in the semantic structure. This semantic feature is very productive, and it justified the meaning of a few hundred of collected phrases in both languages. The most productive ones are NA: usta – уста, човка and język, jęzor, ozór – език, much less: ząb, zęby – зъб, зъби, wargi – устни, джуки, nos – нос and gardło – гърло. Moreover, in Polish, as opposed to Bulgarian, the functional semantic feature “designed for speaking” was distinguished in the structure of a few other NA: ślina, piersi “klatka piersiowa” and płuca. However, in Bulgarian, this function was as well ascribed to NA: чене, мустаци. The analysed somatic phrases concern two categories: silence and speaking (characterized in terms of starting the action of speaking, the content of the utterance and the manner of speaking). The article demonstrates the characteristics of the motivation of the semantics of the collected phrases in each of the compared languages (e.g. the motives of horse-riding in Polish, the motives of damaging and using up the organs of speech, the motive of fight etc.).
Un(accuracy) Factors of the Mental Map of Dialects: Using vs. Non­using a Dialect
Authors: Merkytė-Švarcienė Erika
Published: June 2016

The aim of the article is to analyse the mental maps of the Western Upper Lithuania youth residing in Šiauliai region and evaluate the links between the accuracy of the mental maps and the ability to use a dialect.The respondents of the questionnaire name three main dialectal speech zones: Upper Lithuania, Lower Lithuania and Dzūkija. It is interesting that the ethnographic region of Suvalkija is not mentioned. It is assumed that the youth of the Upper Lithuania (Šiauliai) associates Suvalkija dialect with the standard language.Most of the respondents from the Upper Lithuania (Šiauliai) marked particular cities, such as Utena, Marijampolė, Mažeikiai, Skuodas, Plungė, Biržai, Telšiai, Šiauliai etc., in the mental map of Lithuania. These cities are the prototypical cities, which are frequently mentioned in other researches. The prototypical cities of the Lower Lithuania dialect are Mažeikiai, Skuodas, Plungė, Telšiai; whereas, the prototypical cities of the Upper Lithuania dialect are Biržai and Utena.A small number of the respondents approve the scientific classification of dialects, which subdivides Lithuania’s dialects into Lower Lithuania and Upper Lithuania dialects.

Communication and Shared Understanding Between Parents and Resident-Physicians at Night
Authors: Khan Alisa , Rogers Jayne E. , Forster Catherine S. , Furtak Stephannie L. , Schuster Mark A. , Landrigan Christopher P.
Published: June 2016

BACKGROUND AND OBJECTIVE:

Communication breakdowns between members of the health care team compromise patient safety and experience. Communication breakdowns with parents, an important but often overlooked part of the health care team, are understudied. Parents may play a particularly important role in nighttime care given decreased staffing and inadequate transitions of care at night. We studied communication breakdowns evidenced by lack of shared understanding between parents and night-team residents about the reason for admission and care plan.

METHODS:

We conducted a prospective cohort study of parents (n = 286) and night-team senior residents (n = 34) from May 1, 2013 to October 31, 2013. Parents and residents rated communication and described patients’ reason for admission, overall plan, and overnight plan. Two physician investigators independently reviewed (κ = 0.63) resident-parent dyads, assigned subsequently dichotomized 4-point overall agreement scores, and rated plan complexity. Using clustered logistic regression, we evaluated relationships among demographics, plan complexity, and shared understanding. We also examined resident and parent perceptions of shared understanding.

RESULTS:

We analyzed data from 257 parent-resident dyads. Among these, 45.1% were rated as lacking shared understanding (agreement score = 1 or 2). In multivariate analysis, higher plan complexity (P < .001) and length of stay (P = .002) were associated with lack of shared understanding; lower parental education was a borderline predictor (P = .05). When surveyed, parents and residents reported that they shared an understanding with one another about care plans in 86.0% and 73.1% of cases, respectively.

CONCLUSIONS:

Parents and night-team residents frequently lack shared understanding. Family-centered care initiatives to improve parent-provider communication and shared understanding may help empower parents as partners in safe and high-quality nighttime care.
Cerebral Palsy, Developmental Coordination Disorder, Visual and Hearing Impairments in Infants Born Preterm
Authors: Acharya Krishna , Pellerite Matthew , Lagatta Joanne , Andrews Bree , Msall Michael E.
Published: June 2016

Motor disabilities and neurosensory impairments are common in survivors of prematurity, and significantly affect quality of life. Cerebral palsy occurs with a much higher prevalence in preterm survivors compared with term infants; however, another less severe but important neuromotor condition is developmental coordination disorder. Visual and hearing impairments are less common, but significantly compound physical disabilities. Early identification and referral for services are important to optimize functioning, learning, and community supports for these children. This article provides a review of prevalence, at-risk factors, presenting signs and symptoms, and management strategies for these conditions.

Published: June 2016

The National Children’s Study (NCS) was an ambitious attempt to map children’s health and development in a large representative group of children in the United States. In this introduction, we briefly review the background of the NCS and the history of the multiple strategies that were tested to recruit women and children. Subsequent articles then detail the protocols and outcomes of 4 of the recruitment strategies. It is hoped that lessons learned from these attempts to define a study protocol that could achieve the initial aims of the NCS will inform future efforts to conceptualize and execute strategies to provide generalizable insights on the longitudinal health of our nation’s children.

Published: June 2016

OBJECTIVE:

In 2009, the National Children’s Study (NCS) Vanguard Study tested the feasibility of household-based recruitment and participant enrollment by using a birth rate probability sample. In 2010, the NCS Program Office launched 3 alternative recruitment methods. We tested whether direct outreach (DO) recruitment could be a more efficient strategy to recruit women of child-bearing age.

METHODS:

The NCS DO recruitment approach recruited women, 18 to 49 years, who were pregnant or trying to conceive using passive recruitment methods emphasizing broad community outreach and engagement to create study awareness. Study mailings to listed households included a pregnancy screening questionnaire to identify potentially eligible women from selected neighborhoods to contact the study center. Unique features of this recruitment approach included the following: (1) expansion of selected neighborhoods to maximize potential participant recruitment and enrollment while minimizing in-person participant contact and (2) offering 2 levels of study participation distinguished by data collection intensity.

RESULTS:

Ten study centers listed 255 475 geographically eligible households for contact representing, on average, 3.3% of households per Primary Sampling Unit. A total of 19 354 women were identified for screening, and 17 421 completed a pregnancy screener representing 6.8% of eligible households. Study-eligible pregnant women were older, more educated, and less likely to be Hispanic than the general population. Only 16% (2786) of 17 421 screened women were study-eligible, and 81.1% of these 2786 women consented to participate.

CONCLUSIONS:

Although feasible, the DO approach recruited a sample of study-eligible pregnant women significantly different from the population. This recruitment approach was labor intensive for the yield of enrolled women.
Contribution to the Soil-dwelling Mite Fauna of the Hungarian Agroecosystems (Acari)

A key to the Egyptian signiphorid species is included.
Induction of Resistance with Benzothiadiazole in Sunflower: a Comparison of Biotrophic vs. Necrotrophic Pathosystems
Authors: Körösi K. , Virányi F. , Barna B. , Bán R.
Published: June 2016

In the present work we aimed at comparing the effect of benzothiadiazole (BTH) treatment on defence reactions of sunflower plants to downy mildew and white rot diseases. BTH treatment resulted in reduced disease symptoms in biotrophic and in the early stage of the necrotrophic interactions. To get a better insight into the effect of BTH, changes in the activities of polyphenol oxidase and peroxidase enzymes, as well as the expression of the host response-associated sunflower genes were examined in the plants. Inoculation with Plasmopara halstedii enhanced the polyphenol oxidase and peroxidase enzyme activities, while inoculation with Sclerotinia sclerotiorum did it only at 4 dpi. However, most importantly, in each case extracts from BTH pretreated and inoculated plants showed the highest polyphenol oxidase and peroxidase enzyme activities. Similarly, the accumulation of GST and PDF transcripts was detected following inoculations with both biotrophic and necrotrophic pathogens, and again, BTH pre-treatment enhanced GST and defensine gene activities in the inoculated plants. We suggest that induction of enzyme activities, as well as of the elevated expression of GST, PDF and PR5 genes by BTH pre-treatment may be a significant part of the induced resistance of sunflower to downy mildew and white rot (white mold).
Bacterial Diseases of Wheat in the Southern Ural: Manifestations, Biological Characteristics and Monitoring Features
Authors: Glinushkin A. P. , Beloshapkina O. O. , Solovykh A. A. , Sudarenkov G. V. , Molnár J.
Published: June 2016

The paper presents the results of a long-term monitoring of bacterial diseases of wheat in the steppe zone of the Southern Ural. A clear domination of the genus Xanthomonas over the genus Pseudomonas has been revealed (60 and 11% of the total samples collected, respectively). The frequency of a winter wheat infection with these two pathogens exceeded that of the spring wheat. The field phytosanitary assessment resulted in the observation of the earlier unknown manifestation of the Xanthomonas infection called as tip bacteriosis.

The frequency of wheat infection with Xanthomonas sp. almost did not depend on the relief type, observation period, and sowing date, though the frequency of infection observed for the northern slope and lowland clearly exceeded those observed for other relief types. The frequency of infection with Pseudomonas sp. clearly depended on the sowing date and local relief type reaching the maximum at the lowlands (19–27%), so this relief type can be considered as a “signal” point for the early diagnostics of this pathogen.

Modelo de segmentação e avaliação multicritério de fornecedores para micro e pequena empresa
Authors: Moura Santos Luiz Felipe de Oliveira , Osiro Lauro
Published: June 2016

Diversos modelos de segmentação e avaliação multicritério de fornecedores têm sido apresentados na literatura, entretanto poucos são voltados para as características das micro e pequenas empresas (MPE), que possuem recursos escassos e buscam ferramentas com grande contribuição marginal em sua aplicação. O objetivo deste trabalho é apresentar uma proposta de segmentação e avaliação da base de fornecedores voltada para o cenário das MPE´s e ilustrar sua viabilidade com estudo de caso em uma pequena fábrica de móveis. Os resultados apresentados mostram que os benefícios diretos do modelo não representam grandes contribuições marginais, mas os indiretos e o processo de estruturação desenvolvido favorecem decisões e ações consensuais importantes para o crescimento dessas organizações.

Published: June 2016

A trajetória das empresas familiares é marcada pela cultura organizacional que se constitui a partir dos princípios organizacionais instituídos pelos valores de seu fundador. Quando a organização passa por um processo sucessório, muitos conflitos podem ser gerados, especialmente se ocorrer de modo repentino e sem preparação da equipe. O objetivo deste estudo foi avaliar o impacto gerado na cultura organizacional frente ao processo sucessório vivenciado em um laboratório de análises clínicas que atua há mais de 40 anos no município de Passo Fundo/RS. O estudo foi desenvolvido a partir da comparação da percepção dos colaboradores sobre a mudança na gestão. Os dados foram obtidos por meio de um questionário estruturado, o qual foi aplicado no ambiente de trabalho a todos os colaboradores. A percepção dos membros da unidade é positiva quanto ao processo sucessório, sem mudanças bruscas na cultura da organização, sendo de importante destaque que a sucessão ocorra de forma planejada.

Como resultado, estimou-se uma redução potencial de lead time de mais de 70% (de 71 para 19 dias). Com as melhorias propostas, procurou-se um ponto de equilíbrio diante do trade-off entre produção mais flexível com lotes reduzidos e menores tempos totais de set up com produção em grandes lotes
Duodenum inclusion in alimentary transit for preventing or correcting nutritional deficiencies resulting from Roux-en-y gastric bypass in obesity treatment
Authors: CENEVIVA REGINALDO
Published: June 2016

ABSTRACT Nutritional and metabolic complications can develop after Roux-en-Y gastric bypass (RYGB) when there is an exaggerated response to the anatomical and functional changes or when there is inadequate nutritional supplementation. Severe malnutrition is rare, but deficiencies of vitamin B12, iron, calcium and thiamin, metabolic bone disease and gallstones are common after RYGB. Shortage of vitamin B12, iron, calcium and also cholelithiasis are caused at least partially by excluding the duodenum and proximal jejunum from food transit. We designed a new procedure, with the maintenance of the duodenum and proximal jejunum in the gastrointestinal transit through interposition of jejunal loop, as a primary operation to prevent such deficiencies or as corrective surgery for severe malnutrition after RYGB with failure in responding to conservative treatment.

Resumo Avaliaram-se os efeitos de níveis de correção da fertilidade do solo (testemunha, calagem, adubação e calagem + adubação) e da idade de rebrota (21, 28, 35, 42, 49, 56, 63, 70, 77 e 84 dias) sobre a dinâmica de crescimento e rendimento de forragem de Trachypogon plumosus em Roraima. O aumento da idade de rebrota resultou em maiores rendimentos de matéria seca (MS), taxa absoluta de crescimento (TAC), taxa de assimilação líquida (TAL), razão de área foliar (RAF) e índice de área foliar (IAF), ocorrendo o inverso quanto à taxa média de crescimento (TMC). A gramínea mostrou-se responsiva à melhoria da fertilidade do solo. A calagem + adubação ou a adubação proporcionaram maiores rendimentos de MS (1.934 e 1.661 kg ha-1), TAC (36,6 e 31,5 kg ha-1 dia-1), TMC (32,5 e 27,9 kg ha-1 dia-1), TAL (4,993 e 4,152 g/m2), RAF (152,9 e 140,9 cm2/g) e IAF (2,42 e 2,14). Para otimizar a eficiência de utilização da forragem produzida e reduzir perdas por senescência da gramínea, o período mais adequado de sua utilização, durante o período chuvoso, situa-se entre 56 e 63 dias com o uso de adubação e calagem + adubação e entre 63 a 70 dias para a testemunha e a calagem.

Resumo A cama de aviário é um aspecto de enorme relevância para a avicultura de corte, por influenciar tanto no desempenho zootécnico das aves como nas características de carcaça. Este trabalho objetivou avaliar o desempenho produtivo e o rendimento de carcaça e de vísceras de frangos criados em diferentes materiais de cama aviária. No experimento, foram avaliados 192 pintos, da linhagem Ag Ross, a partir dos 10 dias de vida, distribuídos em 16 unidades experimentais, com 12 aves em cada parcela. Os tratamentos consistiram de quatro materiais de cama (maravalha, capim elefante seco, casca de arroz e areia), com quatro repetições cada. Aos 42 dias de vida, as aves foram pesadas, abatidas e evisceradas. Foram calculados os parâmetros de peso médio, ganho de peso, consumo alimentar, conversão alimentar, viabilidade, rendimento de carcaça e das vísceras comestíveis (coração, moela e fígado). Entre os materiais de cama testados, não houve diferenças significativas nos parâmetros avaliados, porém o ganho de peso das aves criadas em cama de areia foi significativamente superior em relação às aves criadas em cama de capim elefante seco. Concluiu-se que a maravalha, a casca de arroz, o capim elefante seco e a areia podem ser usados como material de cama aviária para frangos de corte sem influenciar no desempenho produtivo e nos rendimentos de carcaça e vísceras comestíveis.

Resumo O objetivo deste trabalho foi avaliar o efeito da adição de gema de ovo (GO) sobre a cinética dos espermatozoides de tambaquis após a criopreservação. Utilizaram-se vinte machos de tambaquis (n= 4 pools), que foram induzidos hormonalmente com extrato hipofisário de carpa, para espermiação. Quatorze horas após a indução, realizou-se a coleta seminal. O sêmen de cada pool foi diluído em Ringer adicionado de 10% de dimetilsulfóxido (DMSO) acrescido ou não de GO (T1: sem acréscimo de GO; T2: com 5% de GO e T3: com 10% de GO). O sêmen tratado foi envasado em palhetas de 0,5 mL, congelado em vapor de nitrogênio líquido (dry shipper-30 min/-153 °C) e posteriormente transferidas para nitrogênio líquido. As palhetas foram descongeladas em banho-maria a 37 °C/30 segundos. A taxa de motilidade (%) e a velocidade curvilinear espermática (µm/s) foram analisadas em sistema computadorizado (CASA). Os dados foram expressos em média ± desvio padrão e foi aplicado o teste de Tukey (P<0,05). Houve uma redução significativa na porcentagem de espermatozoides móveis e velocidade curvilinear após a adição de GO independente da concentração. Logo, a adição de GO ao Ringer + DMSO teve efeito negativo sobre a motilidade do sêmen congelado de tambaqui.

Resumo Objetivou-se determinar a exigência nutricional de cálcio e a melhor relação cálcio:fósforo em rações para poedeiras leves de 24 a 40 semanas de idade. Foram utilizadas 324 aves Hy-Line W-36, distribuídas em delineamento inteiramente casualizado, esquema fatorial 3x3, sendo três níveis de cálcio (3,9; 4,2 e 4,5 %) e três relações cálcio/fósforo (9,3; 10,53 e 12,12/1), totalizando nove tratamentos, seis repetições e seis aves por unidade experimental. Avaliou-se o desempenho produtivo, a qualidade do ovo, as características ósseas, o balanço de cálcio e fósforo e a mortalidade. Não houve interação (P>0,05) entre os níveis de cálcio e as relações cálcio/fósforo para nenhuma das variáveis, porém os níveis de cálcio promoveram efeito (P<0,05) sobre o peso e porcentagem da casca, cálcio na casca, ovos perdidos, consumo de cálcio e fósforo, cálcio e fósforo na excreta, cálcio e fósforo retido. A relação cálcio/fósforo influenciou significativamente (P<0,05) o consumo de ração, ganho de peso, conversão alimentar, consumo de cálcio e fósforo, fósforo na excreta e fósforo retido. Rações contendo 4,5% de cálcio e relação cálcio:fósforo de 12,12:1, correspondendo ao consumo de cálcio de 3,71 g/ave/dia e de fósforo de 306 mg/ave/dia, garantem desempenho satisfatório em rações para poedeiras leves no período de 24 a 40 semanas.

ABSTRACT: CONTEXT AND OBJECTIVE: The prevalence of vitamin B12 deficiency varies from 5.8% to 30% among patients undergoing long-term treatment with metformin. Because of the paucity of data on Brazilian patients, this study aimed to determine the frequency of B12 deficiency and related factors among Brazilian patients with type 2 diabetes mellitus (T2DM) using metformin. DESIGN AND SETTING: Cross-sectional study at a public university hospital. METHODS: Patients with T2DM and a control group of non-diabetics were included. Serum B12 levels were measured and biochemical B12 deficiency was defined as serum levels < 180 pg/ml. Associations between B12 deficiency and age, duration of T2DM, duration of use and dosage of metformin, and use of proton pump inhibitors (PPIs) or histamine H2 antagonists were determined. RESULTS: 231 T2DM patients using metformin (T2DM-met) and 231 controls were included. No difference in the frequency of PPI or H2-antagonist use was seen between the groups. B12 deficiency was more frequent in the T2DM-met group (22.5% versus 7.4%) and this difference persisted after excluding PPI/H2-antagonist users (17.9% versus 5.6%). The factors that interfered with serum B12 levels were PPI/H2-antagonist use and duration of metformin use ≥ 10 years. Use of PPI/H2-antagonists was associated with B12 deficiency, with an odds ratio of 2.60 (95% confidence interval, 1.34-5.04). CONCLUSIONS: Among T2DM patients, treatment with metformin and concomitant use of PPI/H2-antagonists are associated with a higher chance of developing B12 deficiency than among non-diabetics.

Em geral, os artigos na área de ensino sobre propagação de pulsos ou de ondas estacionárias utilizam fios ou arames muito leves, cujos pesos são desprezíveis diante das tensões aplicadas. Essa aproximação simplifica tanto a equação de onda, tornando-a linear, como a relação entre a tensão e a velocidade da onda. Entretanto, esse procedimento restringe os experimentos e exige o uso de sensores e/ou equipamentos mais caros para extrair dados confiáveis. Diferentemente, o objetivo deste trabalho foi criar e analisar um experimento didático barato e eficiente para a obtenção da relação entre a velocidade e a tensão de um pulso e da densidade linear de uma corda, cuja massa não fosse desprezível. Nessa situação, a corda não fica em linha reta, mas pende devido ao seu próprio peso formando uma curva chamada catenária. Para a coleta de dados, foram empregados somente uma câmera de filmagem de um smartphone e um software gratuito de videoanálise. Os diferentes modelos teóricos aplicados na interpretação dos resultados permitiram uma compreensão mais ampla e profunda do experimento. A análise dos resultados revelou uma variação da acurácia e precisão de acordo com os modelos matemáticos adotados. Isso possibilitou uma interessante visualização de que o trabalho experimental não depende somente dos equipamentos empregados, mas é indissociavelmente entrelaçado com as respectivas teorias. Além disso, as diferentes formas de modelar um mesmo fenômeno, com uma gradação de complexidade, proporcionam abordagens ajustadas para os níveis médio e superior, bem como para os diversos cursos de graduação.
O antigo adapta-se ao moderno: verificação do valor da Unidade Astronômica a partir do trânsito de Vênus reproduzido com o software Stellarium

A distância Terra-Sol, conhecida como Unidade Astronômica (UA), tem papel fundamental para a Astronomia: ela fornece uma escala de distâncias dentro do nosso sistema solar e serve como base para a medida de distâncias entre o Sol e estrelas próximas. Neste trabalho, apresentamos uma das maneiras para se obter a UA a partir dos trânsitos de Vênus pelo disco solar. Esta é uma adaptação do método de Halley e foi aplicado a partir das imagens obtidas pelo software livre de Astronomia Stellarium. Encontramos o valor (1, 4±0, 3)⋅108km, em concordância de 93, 6% com o valor aceito pela literatura. A revisão do método de obtenção da Unidade Astronômica a partir do trânsito de planetas fundamenta-se por razões tanto pedagógicas quanto científicas: este trabalho pode ser facilmente reproduzido em salas de aula tanto do ensino médio quanto superior em cursos de introdução à Astronomia. Além disso, o trânsito de Vênus de 2012 foi utilizado para a determinação do raio do Sol com incerteza de apenas 15km, justificando assim o seu estudo. Por fim, este trabalho fornece um teste de autoconsistência do Stellarium, uma vez que determinamos por meios geométricos o valor da UA utilizado pelo programa.
