The Association Between Web-Based or Face-to-Face Lifestyle Interventions on the Perceived Benefits and Barriers to Exercise in Midlife Women: Three-Arm Equivalency Study (Preprint)
Authors: McGuire Amanda Mary , Seib Charrlotte , Porter-Steele Janine , Anderson Debra Jane
Published: May 2018

BACKGROUND

Noncommunicable diseases pose a significant threat to women’s health globally, with most diseases being attributed to modifiable risk factors such as physical inactivity. Women perceive a range of benefits and barriers to exercise; however, there is little evidence about the effect of different lifestyle intervention delivery modes on perceptions of exercise.

OBJECTIVE

This study aimed to compare the effect of a multiple health behavior change (MHBC) intervention called the Women’s Wellness Program. This intervention was delivered in 3 different modes on perceived exercise benefits, perceived exercise barriers, and actual physical activity and exercise in midlife women.

METHODS

Women aged 45 to 65 years were recruited via the study website. They were assigned in blocks to 3 different treatment groups (A: Web-based independent; B: face-to-face with nurse consultations; and C: Web-based with virtual nurse consultations). All participants received the 12-week intervention that utilizes principles from social-cognitive theory to provide a structured guide to promote healthy lifestyle behaviors with an emphasis on regular exercise and healthy eating. Data were collected using a self-report Web-based questionnaire at baseline (T1) and postintervention (T2) including perceived exercise benefits and barriers and exercise and physical activity. A data analysis examined both within- and between-group changes over time.

RESULTS

Participants in this study (N=225) had a mean age of 50.9 years (SD 5.9) and most were married or living with a partner (83.3%, 185/225). Attrition was 30.2% with 157 participants completing the final questionnaire. Women in all intervention groups reported a significant increase in positive perceptions of exercise (P<.05); a significant increase in exercise and overall physical activity (P<.01) with moderate-to-large effect sizes noted for overall physical activity (d=0.5 to d=0.87). Participants receiving support from registered nurses in the face-to-face and Web-based groups had a greater magnitude of change in benefit perceptions and physical activity than those in the Web-based independent group. There was no significant change in exercise barrier perceptions within or between groups over time.

CONCLUSIONS

The results of this study suggest that the (MHBC) intervention is effective in increasing exercise benefit perceptions, overall physical activity, and exercise in midlife women. Although Web-based programs are cost-effective and flexible and can be delivered remotely, providing a range of options including face-to-face group delivery and personalized electronic health coaching from registered nurses has the potential to enhance participant engagement and motivation.
Increasing Need for an eHealth Impact Framework for Africa (Preprint)
Authors: Broomhead Sean , Mars Maurice , Scott Richard , Jones Tom
Published: May 2018

BACKGROUND

Efforts by African countries to improve healthcare and citizens’ health within challenging resource limitations put considerable pressure on investment decisions. eHealth is believed to have potential to strengthen health systems and is now seen by some entities as a determinant of health, yet its impact is not well estimated in advance or measured after implementation. This is an obstacle to the effective allocation of healthcare resources and limits national and regional abilities to develop eHealth and realise its potential in health systems transformation.

OBJECTIVE

A broad conceptual framework for appraising eHealth impact could help selection of the best course of action by informing individual steps, including: identification of promising initiatives, choosing between eHealth options, motivating for financing, managing implementation, preparing for obsolescence, analysing achievements, and promoting sustainability. Such insight could help strengthen and transform healthcare, provide benchmarks for oversight and Monitoring and Evaluation (M&E), and improve individual and population health. Such frameworks exist, but do not address the needs of African countries.

METHODS

Desktop literature review to explore African countries’ eHealth context and the need for an eHealth economic appraisal framework.

RESULTS

Unique aspects of Africa’s health context are elucidated, particularly relating to resource constraints and health strengthening priorities. The influence of these aspects on eHealth development, and how to address factors such as affordability, value for money and risk, are highlighted. Key eHealth appraisal terms are clarified.

CONCLUSIONS

The paper presents the role of eHealth impact appraisal in appraising eHealth options for African countries and describes aspects critical for an eHealth impact framework for Africa.
Data Collection Approaches to Enable Evaluation of a Massive Open Online Course About Data Science for Continuing Education in Health Care: Case Study (Preprint)
Authors: Alturkistani Abrar , Majeed Azeem , Car Josip , Brindley David , Wells Glenn , Meinert Edward
Published: May 2018

BACKGROUND

This study presents learner perceptions of a pilot massive open online course (MOOC).

OBJECTIVE

The objective of this study was to explore data collection approaches to help inform future MOOC evaluations on the use of semistructured interviews and the Kirkpatrick evaluation model.

METHODS

A total of 191 learners joined 2 course runs of a limited trial of the MOOC. Moreover, 7 learners volunteered to be interviewed for the study. The study design drew on semistructured interviews of 2 learners transcribed and analyzed using Braun and Clark’s method for thematic coding. This limited participant set was used to identify how the Kirkpatrick evaluation model could be used to evaluate further implementations of the course at scale.

RESULTS

The study identified several themes that could be used for further analysis. The themes and subthemes include learner background (educational, professional, and topic significance), MOOC learning (learning achievement and MOOC application), and MOOC features (MOOC positives, MOOC negatives, and networking). There were insufficient data points to perform a Kirkpatrick evaluation.

CONCLUSIONS

Semistructured interviews for MOOC evaluation can provide a valuable in-depth analysis of learners’ experience of the course. However, there must be sufficient data sources to complete a Kirkpatrick evaluation to provide for data triangulation. For example, data from precourse and postcourse surveys, quizzes, and test results could be used to improve the evaluation methodology.
Altruismo y empatía en situaciones que implican costos personales imprevisibles
Authors: Alves de Amorim Débora , Rodrigues Sampaio Leonardo , Eulálio Cabral Guilherme Ribeiro
Published: May 2018

El presente estudio tuvo como objetivo investigar la influencia de los sentimientos empáticos sobre el comportamiento altruista de jóvenes adultos. 60 estudiantes de 18 a 35 años de edad participaron de un experimento en el que tuvieron que decidir dar o no rifas a una persona desconocida, después de participar en un juego de azar. Los biletes se obtuvieron después de ganar un concurso de memoria. 30 participantes fueron asignados a una condición experimental denominada "neutral", en la cual tomaron libremente sus decisiones distributivas, y los otros 30 fueron asignados a una condición "emocional", durante la cual se indujeron sentimientos empáticos, utilizando un video. Los resultados indicaron que el sexo de los participantes y la manipulación experimental influyó en el comportamiento del juego, dejando a los participantes en la "condición emocional" más propensos al comportamiento altruista que los participantes en la condición "neutral". Además, los hombres ayudaron más en una condición de alto costo que las mujeres. Estos resultados apuntan a que la influencia de la preocupación empática sobre el comportamiento altruista en una situación que implica riesgo, podría estar mediada por el sexo y que las relaciones entre estas variables necesitan ser mejor observadas en estudios sobre el comportamiento distributivo.

La presente investigación tiene como objetivo determinar la relación entre el Sistema de Tareas Diagnósticas (STD) y la lectura en una muestra de niños cubanos en el 1º y 2º grado. Se aplicaron tres procedimientos: (1) correlaciones entre el STD y la lectura, (2) ANOVA de la Regresión y (3) Regresión jerárquica. Las correlaciones indicaron que las 17 tareas tienen una significativa correlación con la lectura en los dos grados escolares. Sin embargo, el ANOVA de regresión mostró cuatro tareas cognitivas: Análisis fónico, Ordenamiento de láminas, Solución de matrices y Relaciones cuantitativas. En el 2do grado, se destacaron tres tareas: Ordenamiento de láminas, Coordinación viso – motora y Solución de problemas. En el 1er grado, la Regresión jerárquica indicó la importancia de Análisis fónico y el Ordenamiento de láminas por encima de las demás.  En el 2do grado, indicó Ordenamiento de láminas y la Coordinación viso – motora. En resumen, las habilidades fonológicas y el razonamiento son procesos básicos que subyacen en la adquisición de la lectura en los primeros grados escolares.

Published: May 2018

Este estudio se fundamentó en la hipótesis de sensibilidad de la teoría del apego que relaciona la crianza sensible con la seguridad del apego. Tuvo como objetivo analizar la relación entre la sensibilidad de 16 figuras cuidadoras y la seguridad del apego de sus hijos preescolares de desarrollo típico, residentes en Quito, Ecuador. Para la medición se utilizaron dos instrumentos: Maternal Behavior for Preschooler Q-set y Attachment Behavior Q-set Version 3.0, en su adaptación latinoamericana. En comparación con otros estudios con población latina, en este trabajo se encontró un nivel de sensibilidad similar al previamente reportado y un nivel de seguridad ligeramente más alto. En cuanto a la relación entre ambas variables, se halló a la sensibilidad como predictora de la seguridad del apego. Al ser Ecuador un país pluricultural, se recomienda replicar este estudio en grupos de otros contextos culturales y con otras condiciones de desarrollo.

Estudantes indígenas em universidades brasileiras: um estudo das políticas de acesso e permanência
Authors: Bergamaschi Maria , Doebber Michele , Brito Patricia
Published: May 2018

Este artigo aborda a presença indígena no ensino superior brasileiro baseado em pesquisa em universidade que executa política afirmativa para ingresso e permanência de estudantes indígenas. Analisa também teses e dissertações, distribuídas em diferentes programas de pós-graduação, que tematizam o ingresso de estudantes indígenas (implantação de políticas de acesso, processos seletivos para ingresso) e questões relacionadas à sua permanência na universidade (programas de apoio financeiro e pedagógico, relação institucional com os estudantes, ações de acompanhamento e promoção da permanência). O acompanhamento dos estudantes considerou os depoimentos e a convivência com estudantes indígenas no espaço acadêmico. Dados mostram que a presença indígena no ensino superior oferece possibilidades de autorreflexão sobre as práticas pedagógicas da instituição de ensino superior e seu papel social. Também apontam que a permanência dos estudantes indígenas é um grande desafio para universidades e que diálogo e postura receptiva aos conhecimentos originários podem ser o primeiro passo para efetivar processos de interculturalidade no ensino superior.

It concludes with recommendations that other research teams can follow when conducting similar research that crosses disciplinary and international borders.
How the unconference approach can increase stakeholder engagement
Authors: Bazely Dawn R. , Dubreuil Annette , Nanayakkara Lushani
Published: May 2018

Researchers in the fields of environmental science, conservation biology and sustainability studies recognize the importance of engaging stakeholders. Due to implicit or unconscious bias, it is highly likely that when researchers prepare their lists of people and groups who may be affected by, or interested in, their research, some stakeholders will be omitted. Use of Open Space Technology, part of the Unconference engagement framework, in the early stages of research, can diversify and increase stakeholder participation.
La planificación urbana y el tráfico rodado: las ideas de Alker Tripp en la URSS
Authors: Khairullina Elvira
Published: May 2018

El uso masivo del automóvil desde principios del siglo XX en Europa provocó problemas de tráfico, y con ello, la necesidad de replantear los métodos de la planificación urbana. En 1943 Alker Tripp editó en Londres un libro relevante donde abordó temas importantes como la organización del tráfico y su relación con la ciudad. Durante el periodo de posguerra en el contexto del establecimiento del concepto de tráfico en la URSS, el libro provocó gran interés y fue rápidamente traducido al ruso. Como resultado de ello, las ideas de A. Tripp influyeron en la teoría de la planificación urbana soviética en las décadas de los 50 y 60.
Résidencialisation urbaine: seguridad espacial y normalización social en las periferias sensibles francesas
Authors: Manzano Gómez Noel Antonio
Published: May 2018

El presente artículo aborda la residencialización de las periferias francesas, proceso de renovación urbana fundado en la sustitución de grandes conjuntos de vivienda social por pequeñas unidades residenciales cerradas. Protegidas por importantes medidas de control y vigilancia, el nuevo tipo de tejido urbano así proyectado pretende corregir la percepción de inseguridad y los usos de los espacios comunes de los vecindarios, atrayendo así clases medias a entornos urbanos fuertemente estigmatizados. Presentando las teorías sociales en las que dicho proceso se ha fundamentado, y los resultados de un trabajo de campo llevado a cabo en la periferia de Paris, el artículo discute tanto la adaptación de los vecinos a estos nuevos entornos, como el tipo de ciudad que está emergiendo de dicho proceso.

Más allá del Parque Posindustrial: el legado socio-espacial de Fundidora de Fierro y Acero de Monterrey visto a través de sus barrios obreros
Authors: Reyna Monrreal Juan José
Published: May 2018

Aunque ampliamente reconocido por su parque posindustrial, el legado urbano de Fundidora trasciende las fronteras de sus hornos y necesita ser abordado en los barrios, escuelas, e infraestructura que la compañía planificó, diseñó, construyó y subsidió en toda la ciudad. El Fraccionamiento Buenos Aires de 1950 y el Fraccionamiento Adolfo Prieto de 1970, son algunos de los ejemplos más antiguos de comunidades planificadas en la municipalidad, una particularidad excepcional entre los distritos obreros coetáneos. Como parte de la historia de la ciudad, ambos barrios representan la contribución de Fundidora en la modernización del urbanismo y la arquitectura de Monterrey.
Nobleza media, clientelismo y violencia en la ciudad bajomedieval: los Sarmiento, Burgos y el perdón real de 1479
Authors: Guerrero Navarrete Yolanda
Published: May 2018

El perdón real de 1479 ha sido evaluado por la historiografía como un episodio más a sumar en lo que constituye ya un lugar común aceptado por todos los autores: la completa pacificación del reino culminada en 1480 por los Reyes Católicos. Sin poner en duda, lo que considero una evidencia incuestionable, la pacificación del reino, el objetivo del presente trabajo es aprovechar la detallada relación que proporcionan los libros de actas burgaleses para analizar el alcance de dicho perdón real y la reacción de la sociedad burgalesa ante el mismo, a fin de profundizar en el significado, consecuencias y términos de dicha pacificación que a mi entender implicó una intensificación notable del proceso de “nobilización” de las ciudades de realengo, que reforzaría el paralelismo entre centralización y señorialización, que considero fue el hilo conductor de la génesis, a finales del siglo XV, de la monarquía feudal centralizada, también llamada Estado Moderno o Monarquía hispánica.
Dampak perubahan iklim pada produksi apel di Batu Malang Impacts of climate change on production of apple in Batu Malang
Authors: Ruminta Ruminta
Published: May 2018

Perubahan iklim telah menjadi isu penting yang mengakibatkan kenaikan suhu global, perubahan pola curah hujan, kenaikan muka air laut, dan peningkatan frekwensi dan intensitas cuaca ekstrim. Perubahan iklim mempunyai pengaruh signifikan pada bidang pertanian, karena pertanian mempunyai ketergantungan yang kuat terhadap unsur iklim. Terkait dengan hal itu telah dilakukan penelitian dampak perubahan iklim terhadap produksi tanaman apel di wilayah Batu Malang Jawa Timur. Penelitian bertujuan untuk mengetahui dampak perubahan unsur iklim yaitu temperatur dan curah hujan terhadap produksi apel dan mengidentifikasi usaha adaptasi yang harus dilakukan oleh para petani. Hasil penelitian menunjukkan bahwa wilayah  Batu Malang telah mengalami perubahan iklim. Dampak perubahan iklim tersebut terhadap penurunan produksi apel  tidak signifikan.  Penurunan produksi apel di Batu Malang  lebih disebabkan oleh faktor non iklim seperti: tanaman apel sudah berumur tua; budidaya apel kurang intensif; konversi lahan tanaman apel; dan harga apel yang semakin turun.  Adaptasi terpenting yang harus dilakukan oleh petani adalah rehabilitasi tanaman apel; menanam bibit apel yang unggul yang mampu beradaptasi dengan perubahan iklim; dan mengintensifkan teknik budidaya apel. Kata kunci : Apel ∙ Dampak ∙ Perubahan iklim

Published: May 2018

Produksi jagung di Indonesia belum mampu menutupi tingginya permintaan jagung nasional. Padi hitam pun secara umum mengalami kondisi yang sama. Upaya peningkatan produksi jagung dapat ditingkatkan melalui penggunaan jagung hibrida. Namun, penggunaan varietas hibrida akan mendatangkan permasalahan lingkungan karena over aplikasi pupuk sintetis. Modifikasi lingkungan secara aktif pada budidaya hibrida jagung dan padi hitam dapat dilakukan dengan cara tumpangsari. Hal ini merupakan salah satu solusi yang ramah lingkungan karena memperkaya bahan organik dan anorganik melalui pemilihan tanaman kedua secara selektif, mencegah gagal panen, diversifikasi pangan dan asupan nutrisi yang berbeda. Tujuan dari penelitian ini adalah mendapatkan varietas jagung hibrida unpad yang memiliki penampilan morfologi dan agronomi terbaik dalam tumpangsari dengan padi hitam di dataran tinggi. Percobaan lapangan menggunakan rancangan acak kelompok dengan 18 perlakuan jagung hibrida unpad dan 1 varietas komersil sebagai cek. Untuk mendapatkan Jagung hibrida terpilih analisis dilanjutkan dengan uji Least Significant Increase (LSI). Hasil penelitian memperlihatkan bahwa dalam kondisi tumpangsari dengan padi hitam, karakter panjang daundengan hibrida terpilih JH6, JH17, JH12, dan karakter bobot biji pipilan kering, dengan hibrida terpilih JH17, JH12, JH8, JH1 dan JH14, memberikan hasil tertinggi dibandingkan cek. Panjang daun dan bobot biji pipilan kering merupakan karakter penting terkait dengan hasil yang tinggi pada jagung hibrida. Namun, memberikan hasil yang sama pada tinggi tongkol dan kandungan klorofil. Untuk mendapatkan jagung hibrida unpad yang lebih stabil dan adaptif perlu dilakukan pengujian lebih lanjut pada musim dan ketinggian tempat yang berbeda.Kata kunci : Morfologi-Agronomi, hibrida,  jagung, padi hitam, tumpangsari

An Unknown Correlation in Hexametric Poetry and the Interpretation of the Brevis in Longo Principle
Authors: Abritta Alejandro
Published: May 2018

The goal of this paper is to show that (some) Ancient Greek hexametric poets were not indifferent to the quantity of the final syllable of the verse, by studying the correlation between that quantity and the different possible word ends in the fourth foot of the verse. The results of the study suggest that in some poets there was a certain preference for “rhythmic coherence” within the second colon, which indicates that, even if there was “compositional indifference” regarding the quantity of the last syllable, there was not “actual indifference”.
Images of Dead Poets in Roman Elegiac and Lyric Underworld
Authors: Vasconcellos Paulo Sérgio de
Published: May 2018

In this paper I analyse and compare the representations (or self-representations) of poets in the underworld in elegiac and lyric Roman poetry. I focus especially on five poems: Tibullus I.3; Propertius II. 34; Ovid, Amores II.6 (birds as poets) and III.9; Horace, Odes II.13. It is not my intention to give a detailed interpretation of the whole poems; my principal aim is to analyse how dead poets are pictured in two different genres, the elegiac and the lyric, which share certain features (for instance, we can have in some lyric poems the poetic persona of a lover, the amator, which characterizes erotic elegy discourse, and some similar topics, as the metaphor of love as illness, etc.). At the end of this paper, I will point to the images of dead poets that are (I think) the most representative of the difference between elegiac and lyric genres. In the footnotes I provide some bibliographical references on studies and commentaries about each of the poems I treat here.
Detection of Thallium and Uranium in Well Water and Biological Specimens of an Eastern Croatian Population
Authors: Ćurković Mario , Sipos Laszlo , Puntarić Dinko , Dodig-Ćurković Katarina , Pivac Nela , Kralik Kristina
Published: May 2018

Using inductively-coupled plasma mass spectrometry (ICP-MS), we measured the concentrations of thallium and uranium in local water resources from three villages (Ćelije, Draž, and Potnjani) in eastern Croatia, with the aim to determine if they were associated with the levels of these same elements in the serum, urine, and hair collected from the residents of this area. The exposure of the local population to thallium and uranium through drinking water was generally low. ICP-MS was capable of measuring the levels of both of the elements in almost all of the analysed samples. Although there were differences in the concentrations of both elements in water samples and biological specimens taken from the residents, they did not reach the maximum contaminant level in any of the four sample types studied. Although hair was previously reported as an excellent indicator of occupational and environmental exposure to various elements, our study did not confirm it as a reliable biological material for tracing thallium and uranium levels, mainly due to the very low concentrations of these elements, often well below the detection limit. However, our results have shown that the concentration of thallium and uranium in drinking water can be effectively traced in urine samples.
The Blood is Rich in Different Types of Mesoderm Derived Stem and Progenitor Cells
Authors: Kovačević Filipović Milica
Published: May 2018

The blood and bone marrow have been thoroughly investiagated for more than a century, but we are still gaining surprising new informations. Blood transports different mature cells such as erythrocytes, platelets and granulocytes, but curiously, the blood is also transporting a number of non-differentiated cells of various mesodermal lineages: hematopoietic and mesenchymal stem and progenitor cells, endothelial progenitor cells and very small embryonal like cells are some of the most impressive examples. In adults the bone marrow is the source of practiclly all cells that could be found in the blood. Stem and progenitor cells egress from the bone marrow and home to the bone marrow or various tissues in a highly regulated manner. The fact that the hematopoetic stem and progenitor cells traffic through the blood and repopulate the bone marrow niche is largely explored in stem cell therapy in human medicine. In this review we will briefly describe the main characteristics of stem and progenitor cells, the mechanisms of their mobilization from the bone marrow and homing to target tissues. Also, the history and importance of the fact that different stem, progenitor and precursor cells could be isolated from the blood circulation will be discussed in the light of informations concerning their use in human and veterinary medicine.
Analysis of Genetic Structure of Huchen (Hucho Hucho) in Serbia Inferred From Mitochondrial and Nuclear DNA
Authors: Marić Saša , Razpet Andrej , Nikolić Vera , Snoj Aleš , Simonović Predrag
Published: May 2018

The purpose of this study was to assess the genetic diversity of Serbian huchen and provide guidelines for conservation and management. Fourteen huchen individuals were collected from six localities. For all individuals the mitochondrial DNA control region and the NADH1 gene were sequenced, and two microsatellite loci were genotyped. Sequencing of two mtDNA loci showed the presence of the same haplotypes (Hh_CR_1 and Hh_ND1_1) in all investigated specimens and the complete absence of genetic variability at inter- and intra-populational level. However, analyzed individuals from Serbia have the largest number of control region repeats (average 8.7) compared to all other huchen populations from the Danube basin. Microsatellite data show that the most of Serbian huchens were placed in the “eastern” cluster except one individual from the Drina River which clustered with “western” samples, most likely a consequence of stocking. In spite of only two loci used, four unique alleles found in the studied Serbian and Drina basin population indicate that the Danube basin may possess more region specific alleles than previously thought, which could be of great importance for efficient species management in the future.

Authors: Kaczorek T.
Published: May 2018

The asymptotic stability of positive fractional switched continuous-time linear systems for any switching is addressed. Simple sufficient conditions for the asymptotic stability of the positive fractional systems are established. It is shown that the positive fractional switched systems are asymptotically stable for any switchings if the sum of entries of every column of the matrices of all subsystems is negative.

The paper presents numerical analyses aimed at preliminary assessment of the protective panel effectiveness, which task is to protect the elements of building structures against explosion. For the criterion of assessing the effectiveness of the panel the load capacity of the column made of steel I-beam was chosen. Ultimate force was determined by using advanced computational procedure, which consisted of four stages: preload, blast simulation, dynamic response and static analysis of deformed structure. Blast load was simulated using Lagrangian- Eulerian domain coupling. Results indicated that the application of the protective panel significantly reduces the plastic deformation of the structure.

High strain rate experimental tests are essential in a development process of materials under strongly dynamic conditions. For such a dynamic loading the Split Hopkinson Pressure Bar (SHPB) has been widely used to investigate dynamic behaviour of various materials. It was found that for different materials various shapes of a generated wave are desired. This paper presents a parametric study of Split Hopkinson Pressure Bar in order to find striker’s design variables, which influence the pulse peak shape in the incident bar. With experimental data given it was possible to verify the developed numerical model, which was used for presented investigations. Dynamic numerical simulations were performed using explicit LS-Dyna code with a quasi-optimization process carried out using LS-Opt software in order to find striker’s design variables, which influence the pulse peak shape.

The aim of the study was to evaluate the status of bovine viral diarrhoea virus (BVDV) infection in selected dairy herds in Poland with the use of commercial enzyme linked immonosorbent assay for the detection of specific antibodies (BVDV-Ab ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) for the detection of viral RNA, using bulk tank milk (BTM) samples. Two hundred and thirty-one samples of BTM were collected from 99 dairy herds in Poland. The herds were divided into four different classes according to the Swedish system of classification. The results showed that 70.7% of herds were BVDV antibodypositive. High levels of antibodies in 52.85 % (37 herds in class 3) of all antibody positive herds indicated acute BVDV infection. Thirty five samples with the highest antibody levels were tested by RT-PCR and five of them were positive for viral RNA. Dairy herds in Poland have high levels of antibodies against BVDV in BTM. Since no vaccination was implemented in the herds tested, high seroprevalence of BVDV antibodies in cattle indicates the widespread of BVDV infection in Polish cattle.

For the measurement of tulathromycin distribution in swine plasma an accurate and reliable analytical method was developed. The extraction was performed with oxalic acid buffer (pH=4.0). Plasma samples were cleaned up by solid phase extraction procedure using polymeric cartriges. Chromatographic separation was achieved on a C 18 analytical column using mobile phase consisting of acetonitrile, 0.1% formic acid in gradient mode. Detection was carried out by liquid chromatography tandem mass spectrometry. Azithromycin was used as internal standard. The method has been successfully validated. The recovery from spiked samples ranged from 94% to 110%. The limit of detection was 2 ng/mL and the limit of quantification was 5 ng/mL. The method was developed to investigate the pharmacokinetics of tulathromycin in swine plasma. Applicability of the method was tested with plasma from swine administered with a single dose of tulathromycin.

The aim of the study was to evaluate the immune effects of genetically modified (GM), insect resistant corn (MON810) expressing toxin protein of Bacillus thuringiensis, and glyphosate-tolerant soybean meal (Roundup Ready MON-40-30-2), which are used as the feed mixture components in domestic animals. The study was conducted on 60 pigs (36 fatteners and 24 sows), 20 calves, 40 broilers, and 40 laying hens. Each species was divided into four basic nutritional groups: group I (control) - conventional feed, group II - feed consisted of GM soybean meal and non-modified corn, group III - non-modified soybean meal and GM corn, group IV - GM soybean meal and GM corn. Moreover, in the experiment on fatteners two additional groups were formed: group V - animals fed both conventional soybean meal and bruised grain, and group VI - GM soybean meal and conventional bruised grain. The results of study did not reveal any significant effect of feed mixtures containing GM components on the immune response in all animals regardless of their species and technological producing groups.

Published: May 2018

The issue of how to stimulate economic growth and development remains an open question. The EU structural funds are meant to help solve the problem at the regional level within the framework of the cohesion policy. Only some of these funds are used to directly subsidize businesses that are the engines of growth in a market economy. This paper aims to evaluate whether structural funds have played a positive and significant role in the development of enterprises in a region which does not belong to the economic leaders in Poland. It is based on the results of a direct study, statistical data and evaluation reports, as well as on the economic literature. The direct study was conducted in 2011. It focused on micro-economic projects supported by EU funds in the Lodz region. Interviews were conducted with representatives of 80 enterprises, which had completed at least one such a project. We conclude that the subsidies from structural funds have positively stimulated the modernization of the companies, albeit on a limited scale.
Changes In Competitiveness Among The Visegrad Countries After Accession To The European Union: A Comparative Analysis Based On A Generalized Double Diamond Model
Authors: Molendowski Edward , Żmuda Małgorzata
Published: May 2018

National competitiveness is a buzzword that awakens much interest and controversy. In its broadest perspective, it is seen as a modern way of describing the development efforts of nations in the times of globalization (Reinert 2001, p. 23-42). This means that forces driving the changes in the global economy: liberalization of international trade, booming investment by multinational enterprises and development of regional integration groupings, need to be included into the competitiveness model. Well-known and commonly used approach to national competitiveness: Porter’s diamond of competitive advantage does not however capture this international context. By concentrating solely on the elements of the domestic environment, the model does not show the complicated international linkages that have shaped the competitiveness of many countries. Especially in the case of small, open ‘catching-up’ economies, assessing national competitiveness solely on the basis of the potential of domestic companies, based on local conditions, does not fully reflect their developmental context, which is also driven by the complex networks of international interdependencies. Building upon the generalized double diamond model developed by Moon et al. (2000), this paper explores the extent to which economic relations with international partners and the activities of transnational corporations affect the competitiveness of the Visegrad Group countries, and how this relationship has been changing in the post-accession period. To answer the research problem posed, Eurostat and Global Competitiveness Report data have been gathered to assess the competitiveness variables on both the domestic/national and international levels. It has been shown that integration within the global economy constitutes an essential element of competitiveness for each of the analysed countries.
