Envy and Social Comparison
Authors: van de Ven Niels , Zeelenberg Marcel
Published: September 2018

Upward social comparison can give rise to the emotion of envy: the pain caused by the good fortune of others. We explain what envy is, and what the possible function of envy is to an organism experiencing it. We provide an overview of past work on envy, the distinction between two subtypes (benign and malicious envy), possible antecedents of envy, possible consequences of envy, and the responses to being envied by others. In each of these areas there are clear links to research on social comparison, and research on envy has greatly benefitted from insights from the social comparison literature. Given the surge in research on envy in the last decade, we hope that the findings on envy can also inspire those investigating social comparisons.

The article studies the problem of a gradual change in the direction of urban discourse under the influence of critical re-considering of the heritage in modernists projecting and the range of social and technological initiatives implemented on the verge of 21st century. One of the features that characterizes the modern approach to urban development is a diversity of the material, dedicated to the evolution of urbanism in the 21st century (which deals with various forms of its perspective and retrospective). Such scope of data rises a lot of questions about the development of a certain system of its analysis regarding the balance of dominating topics and tasks. The given article studies main directions of scientific approach to the current state and perspective ways of urban evolution, based mainly on the potential incorporated in the traditional industrial urban development to reflect the phenomena and changes of a post-industrial city.

Published: September 2018

O presente trabalho teve como objetivo mensurar como os contextos, verbal (instrução) e não verbal (figuras), exerceram controle sobre as respostas verbais em um episódio verbal total. Participaram do estudo cinco universitários. O procedimento foi dividido em três fases. Na primeira, manipulou-se o contexto “laranja”; na segunda, “ponto”; na terceira, “tênis”. Todas as fases continham três situações experimentais (SE). Nas SE-1, SE-4 e SE-7, manipulou-se apenas o contexto verbal; nas SE-2, SE-3, SE-5, SE-6, SE-8 e SE-9, manipularamse os contextos verbal e não verbal. O contexto não verbal se deu por figuras, e o verbal, pelo pedido de relato usado como registro das respostas. A análise foi feita entre sujeitos e um intrassujeito, classificando as respostas em acordo ou desacordo com o contexto ou, ainda, como estímulo discriminativo figura (SD), por meio de classes de respostas possíveis preestabelecidas. Verificou-se que os diferentes contextos exerceram controle sobre o significado das palavras no comportamento de escrita.
A tolerância ao atraso do reforçador como cunha comportamental precursora do autocontrole
Authors: Haendel Tatiana Correia , Alvarenga Patrícia
Published: September 2018

Os pressupostos teóricos da Análise do Comportamento e a literatura empírica têm relacionado a tolerância à espera por reforçadores atrasados ao autocontrole. Contudo ainda não foi explorada uma perspectiva desenvolvimental acerca da sua relevância. O objetivo deste estudo foi analisar a tolerância ao atraso do reforçador como uma possível cunha comportamental precursora do autocontrole. Para essa análise foram utilizados textos de Skinner e de outros analistas do comportamento que discutem os construtos de autocontrole, desenvolvimento humano e cunha comportamental, além de artigos empíricos que examinam as relações entre a tolerância ao atraso do reforçador e o autocontrole. Adicionalmente, foram discutidas contingências desenvolvimentais que podem favorecer a tolerância ao atraso do reforçador. Conclui-se que a tolerância ao atraso do reforçador atende a todos os critérios estabelecidos para ser considerada uma cunha comportamental e que, nesse sentido, deve constituir um importante alvo de intervenção na infância, visando ao desenvolvimento futuro do autocontrole.

Published: September 2018

O objetivo deste artigo foi realizar uma revisão da literatura analítico-comportamental sobre intervenções com feedback em vídeo no esporte. Uma busca foi realizada nas bases de dados da Capes, PsycINFO, SPORTdiscus, Web of Science, Pepsic, Indexpsi, Scielo, Pubmed e Google Acadêmico. As palavras vídeo feedback, feedback em vídeo, feedback, intervenção com vídeo e análise de tarefas foram combinadas com as palavras voleibol, esporte, futsal, handebol, basquetebol e futebol. As mesmas palavras foram combinadas com o termo análise do comportamento em inglês e português. Os resultados apontaram um maior número de pesquisas com participantes amadores de modalidades esportivas individuais e que investigaram os efeitos do uso de feedback em vídeo por si só ou feedback em vídeo com modelo especialista. Apenas habilidades técnicas foram investigadas, indicando uma lacuna na literatura quanto aos efeitos sobre variáveis táticas em modalidades individuais e coletivas e com atletas de alto rendimento.

Authors: Ferreira Nayara , Venâncio de Araújo Rafael , Costa Campos Eric
Published: September 2018

With the growing concern to obtain quality food, allied to the aquaculture sector, which has been increasingly important in relation to technology, animal welfare focused on fish is a point that needs to be linked and integrated. The slaughter has several steps that precede, and all of them influence the final quality of the product. These steps are harvest, fasting, transportation and stunning, which can occur by different methods, which affect positively or negatively. Among the practices that are used for slaughter, it includes those that cause less suffering and better quality of meat, being, by electric shock, lethal blow to the head (with insensibiling) and bone marrow section, and those that generate suffering in fish, which are by asphyxiation (in air or ice) and thermal shock, which are the most traditional methods. Therefore, it is necessary to include welfare legislation in the slaughtering of fish, since, like other animals, fish is an animal that is aware of sensations. The objective of this review is to emphasize the importance of welfare in pre-slaughter and fish slaughtering.

La disociación en niños y adolescentes: la variabilidad en la expresión clínica a propósito de dos casos
Authors: Fernandes Abreu A. , Nuñez Sande C. , Pinal Fernández B. , Martínez Alonso B.
Published: September 2018

El término disociación ha pasado de constituir una entidad nosológica a ser relegado a un síntoma, apareciendo disgregado en las diferentes clasificaciones internacionales actuales, lo que lo lleva a ser un concepto teórico, confuso y generador de controversia. El diagnóstico por exclusión que esto implica, hace que sea un trastorno infradiagnosticado en la práctica clínica, lo que trae consigo la escasez de publicaciones, especialmente en población infanto-juvenil. Se debe entender cómo la respuesta a un fenómeno postraumático expresándose clínicamente dependiendo de la propia resiliencia del sujeto. Se exponen dos casos clínicos contrapuestos (disociación mente-mente vs mentecuerpo) que han necesitado ingreso hospitalario. Se precisarían más publicaciones sobre esta patología, para ofrecer a los clínicos un enfoque amplio que facilite el diagnóstico de la disociación como entidad mórbida y no únicamente como diagnóstico de exclusión, así como su tratamiento y pronóstico.

Naciones mediáticas. Los marcos informativos de la consulta sobre la independencia de Cataluña (9-N)
Authors: Ballesteros Herencia Carlos A.
Published: September 2018

La propuesta de celebrar un referéndum sobre la independencia de Cataluña ha recibido una intensa representación informativa en los medios españoles, como correlato de la continua actividad política que ha supuesto. Para contrastar la hipótesis de que los medios catalanes y madrileños realizaran un tratamiento diferente de esta cuestión, se planteó describir los componentes esenciales de los marcos mediáticos utilizados por los principales periódicos sobre este hecho informativo: fuentes, actores protagonistas, acciones descritas y evaluación. Para ello, esta investigación se propuso aplicar la metodología propia de la teoría del framing o enmarcado informativo, realizando un estudio cuantitativo apoyado en la aplicación de la estadística, sobre una muestra de los diarios El País, El Mundo, ABC, La Vanguardia, El Periódico y El Punt Avui. Junto al cálculo de estadísticos descriptivos, se halló también la existencia o no de asociación significativa entre variables. Este tema apareció en portada todos los días en la mitad o más de los medios analizados, con una importancia formal entre alta y máxima. Las principales fuentes y protagonistas fueron las instituciones y los políticos, realizando acciones de tipo político. La prensa madrileña y la catalana evaluaron de modo contrario las noticias protagonizadas por las instituciones catalanas y españolas.
Separable solutions to a brood-parasite dynamics model
Authors: Skakauskas Vladas
Published: September 2018

Common Cuckoo is a brood-parasite which lays its egg in the nest of other bird species and use them to raise its young. We present a Common Cuckoo and a host bird interaction deterministic model taking into account maternal care of offspring. The model consists of a coupled system of integro-partial differential equations subject to the conditions of the integral type. Number of equations in the system depends on a biologically possible maximal number of eggs of the same clutch laid by a host bird. Separable solutions of this model are studied.

On polar relative normalizations of ruled surfaces
Authors: Papadopoulou Ioanna-Iris , Stamatakis Stylianos
Published: September 2018

This paper deals with skew ruled surfaces in the Euclidean space $\mathbb{E}^{3}$ which are equipped with polar normalizations, that is, relative normalizations such that the relative normal at each point of the ruled surface lies on the corresponding polar plane. We determine the invariants of a such normalized ruled surface and we study some properties of the Tchebychev vector field and the support vector field of a polar normalization. Furthermore, we study a special polar normalization, the relative image of which degenerates into a curve.

Modeling of fiber circumplacement around a hole using a streamline approach
Authors: Hartmann Stefan , Kheiri Marghzar Ali
Published: September 2018

The insertion of holes into laminates can be done by producing a fiber reinforced composite plate and, subsequently, drilling the borehole. Alternatively, we can bypass the fibers around the final hole before injecting the matrix material. In the first case, the spatial distribution of the axis of anisotropy, and the structural tensor concerned, are spatially constant. In the second case, i.e. the fiber circumplacement around the hole, a space-dependent anisotropy has to be considered. Instead of the common approach of defining region-wise constant fiber orientations, we propose a continuous formulation of fiber orientations using streamlines. To estimate the final stress and strain state for a unidirectional composite plate, three-dimensional finite element simulations are performed, where spatially constant transverse isotropy is compared to inhomogeneously distributed fiber orientation around the hole. It will turn out that the resulting stress states lead to both reduced stress amplitudes in loading direction as well as compressive strains in lateral direction. A detailed mathematical derivation of the basic equations accompanies the investigations.
Topological asymptotic analysis of an optimal control problem modeled by a coupled system
Authors: Fernandez L. , Novotny A.A. , Prakash R.
Published: September 2018

In this paper, we deal with the topological asymptotic analysis of an optimal control problem modeled by a coupled system. The control is a geometrical object and the cost is given by the misfit between a target function and the state, solution of the Helmholtz–Laplace coupled system. Higher-order topological derivatives are used to devise a non-iterative algorithm to compute the optimal control for the problem of interest. Numerical examples are presented in order to demonstrate the effectiveness of the proposed algorithm.

In this paper, we consider recurrence of bounded solutions to semilinear stochastic integro-differential equations via uniformly exponentially stable resolvent operators family. Concretely, we first establish the existence and uniqueness of the [Formula: see text]-bounded solution to a semilinear stochastic integro-differential equations driven by Lévy processes, and then we show this kind of [Formula: see text]-bounded solution is almost automorphic in distribution or weighted pseudo almost automorphic in distribution under suitable conditions respectively.
Mixed boundary value problems for non-divergence type elliptic equations in unbounded domains
Authors: Cao Dat , Ibraguimov Akif , Nazarov Alexander I.
Published: September 2018

We investigate the qualitative properties of solutions to the Zaremba type problem in unbounded domains for non-divergence elliptic equation with possible degeneration at infinity. The main result is a Phragmén–Lindelöf type principle on growth/decay of a solution at infinity depending on both the structure of the Neumann portion of the boundary and the “thickness” of its Dirichlet portion. The result is formulated in terms of the so-called s-capacity of the Dirichlet portion of the boundary, while the Neumann boundary should satisfy certain “admissibility” condition in the sequence of layers converging to infinity.

Published: September 2018

AbstrakPembangkit Listrik Tenaga Air di Indonesia banyak dipasang menggunakan turbin pelton. Turbin pelton adalah alat yang bekerja untuk mengubah energi kinetik air menjadi energi mekanik berupa putaran poros yang digunakan untuk generator listrik dan menghasilkan tenaga listrik. Desain turbin pelton itu unik, maka perancang harus melakukan perancangan baru setiap akan membuat turbin baru atau turbin pengganti dalam pengembangannya. Penelitian ini bertujuan untuk mengukur kemampuan pembangkit listrik turbin pelton dan menganalisis regresi sistem kerjanya. Dengan menggunakan metode rekayasa peniruan, prototype turbin pelton dibuat agar dapat dilakukan pengukuran analisis regresi terhadap hubungan daya pengisian alternator terhadap jumlah lampu, hubungan putaran alternator (rpm) terhadap jumlah lampu, hubungan daya keluaran terhadap putaran alternator dan hubungan torsi terhadap putaran alternator sehingga dapat digunakan untuk memprediksi parameter-parameter yang akan diperlukan dalam merancang sistem pembangkit listrik turbin pelton nantinya. Dari hasil analisis regresi, diperoleh koefisien korelasi dengan nilai dibawah 1, pendekatan regresi telah cukup memadai dengan nilai koefisien korelasi diatas 0,9. Kesalahan pengukuran dapat terjadi karena berbagai faktor, antara lain dari alat dan sistem yang diukur belum memenuhi kondisi yang ideal. Hasil penelitian ini belum mencapai kondisi ideal, dan masih diperlukan perbaikan sistem prototype secara umum. Sehingga dapat diperoleh hubungan hasil pengukuran dengan hasil perhitungan yang baik. Kata kunci: turbin pelton, daya, torsi, analisis regresi

Mesin pemanen kombinasi untuk padi dimodifikasi untuk memanen jagung. Agar jagung bisa dipanen dengan mesin tersebut maka diperlukan penyesuaian pada beberapa bagian, salah satunya sistem pembersihan mesin pemanen kombinasi. Hal ini disebabkan oleh perbedaan lahan, pohon, dan buah dari padi dan jagung. Penelitian ini bertujuan untuk meningkatkan kebersihan bulir jagung yang telah terpipil dan membuang sampah yang masuk ke dalam ruang penyaringan sehingga diperoleh pembersihan yang optimal serta mengurangi jagung yang terbuang. Metode penelitian menggunakan reverse engineering dengan mengidentifikasi fungsi dari bagian-bagian sistem pembersihan mesin pemanen kombinasi. Pengujian dilakukan di laboratorium dengan kondisi lantai rata dan datar. Pengujian meliputi kadar air jagung, bentuk dan posisi sieve, lebar celah pembuangan, kemiringan penampung jagung, serta pengaruh putaran engine dan kecepatan angin dari blower. Hasil pengujian menunjukkan bahwa kadar air jagung 19% menghasilkan jagung pipilan yang bersih. Agar biji jagung dapat bergerak ke area screw pembawa, perlu kemiringan penampung jagung minimal sebesar 20°. Celah pembuangan sampah dibuat sebesar 65 mm supaya sampah tidak tersumbat pada saat pembersihan  butir jagung. Posisi dan bentuk sieve juga berpengaruh terhadap jumlah jagung yang terbuang dan proses penyaringan. Sieve yang dipasang dengan kemiringan 20° berhasil mengurangi jagung yang terbuang menjadi 4,67% pada putaran engine 1500,2 rpm dan  kecepatan angin dari blower sebesar 1,7 – 3,9 m/s.

Comprehensive analysis of chloroplast intron-containing genes and conserved splice sites in dicot and monocot plants
Authors: Nguyen Sy Dinh , Kang Hunseung
Published: September 2018

Despite the increasing knowledge on the importance of the intron splicing of chloroplast genes during plant growth and stress responses, identification of intron-containing chloroplast genes and determination of splice sites in chloroplast introns are still lacking. Here, we carried out a comprehensive analysis of the chloroplast genome sequences in important plants and crops, including four dicots (Arabidopsis thaliana, Coffea arabica, Nicotiana tabacum, and Panax schinseng) and four monocots (Musa acuminata, Oryza sativa, Triticum aestivum, and Zea mays). The results showed that both dicot and monocot chloroplast genomes harbor 6 intron-containing tRNAs (trnA, trnG, trnI, trnK, trnL, and trnV) and 10-12 intron-containing mRNAs (atpF, rpl2, rpl16, rps16, ndhA, ndhB, petB, petD, rpoC1, rps12, ycf3, and clpP). Notably, rpoC1 and clpP lacked introns in monocot plants, except M. acuminata. Analysis of the nucleotide sequences of chloroplast introns revealed that the 5’-splice sites, 3’-splice sites, and branch-point sites of the chloroplast introns were highly conserved among dicots and monocots. Notably, the 5’-splice sites and 3’-splice sites of the chloroplast introns were similar to those of the nuclear U12 introns, whereas the branch-point sites of the chloroplast introns were homologous to those of the nuclear U2 introns. Taken together, these results indicated that the chloroplast genomes contained strictly limited intron-containing genes with conserved splice sites, suggesting that splicing of chloroplast introns was important for chloroplast biogenesis and function in both dicot and monocot plants.

Published: September 2018

Saltwater intrusion (SI) associated with El Nino phenomenon is a particularly concerned issue in a period of 2015–2016. Salinity evolutions in the Mekong Delta and Vinh Long province are becoming serious. Therefore, this work aimed at assessing changes in saltwater intrusion in Vinh Long province during recent ten years (2007–2016), including changes in the highest, the lowest, and average salinities. Besides, 19 surface water samples were collected and analyzed to evaluate the current status of salinization in 2016. Results showed that the salinity tends to propagate into the infield, especially in Co Chien River (0.4 to 1.2 ‰), followed by Hau River (0.2 to 0.7 ‰) and other inland waterways (0.3–0.6 ‰), leading to certain impacts on agriculture, aquaculture, and water supply in the local in general. In Vinh Long province, Vung Liem and Tra On districts were relative significantly influenced by SI, requiring suitable control measures, particularly in the context of climate change.
Türkiye’deki Kömür Madeni Kazalarına İlişkin Değerlendirme
Authors: DERİN Leyla , VAROL Nehir , UYMAZ Sadi
Published: September 2018

Mining accidents,
considered as technological disasters, are global problems as well as usually
common issues faced by developing countries. These accidents cause considerable
number of deaths, injuries and economic losses worldwide. The statistics show that
mining accidents occurred mostly in the coal mines in Turkey and also in the
world. This is the fact that, in the period of 2010-2015 in Turkey, coal mining
accidents caused approximately 81% of human casualties in the mining accidents.

 

Firedamp explosion,
fire, carbon monoxide poisoning, inundation and collapsing of mine stopes are
the most common causes of coal mining accidents in Turkey. Only in 2014, 301
miners died because of mine fire in the Soma-Eynez underground coal mine and 18
miners also died because of inundation in the Karaman-Ermenek underground coal
mine.

In order to prevent/
mitigate deaths, injuries and economic losses caused by mining accidents, the
primarily step is risk reduction studies because mining accidents are based on
generally preventable issues like infrastructure, technology and management
problems. A successful risk reduction plan for mining accidents requires
analyzing and commenting the factors causing mining accidents in the best way.
This risk approach will allow us to eliminate many mining accidents or overcome
them with the least damage. Some risk reduction studies have conducted for
prevention of mining accidents or reduction of the losses. Actually, there were
serious gaps in the laws about occupational health and safety of workers in
mining sector until 2012. The significant amendments were made to the
regulations with the Act No. 6331 that came into force in 2012. Some amendments
were also made to relevant regulations in 2014. However, the painful experiences
show that the implementing and monitoring of existing regulations and
amendments are insufficient. In that regard, taking and monitoring essential
measures against work accidents caused by the human factor must be the primary
task for mining activities.

 

In this study, risk reduction studies are discussed with evaluating of
the coal mining accidents which occurred in Turkey.

Authors: ÖZĞAN Şükrü
Published: September 2018

Absorbance,
capacitance, conductance, dielectric anisotropy and birefringence properties
and splay elastic coefficient of 4’-Hexyl-4-biphenylcarbonitrile (6CB) and its
mixture with 4’-Octyl-4-biphenylcarbonitrile (8CB) were investigated. The
absorbance was studied using the UV-visible spectrophotometry.
Capacitance, conduction and dielectric
measurements for 6CB and its mixture were performed in  0-1000
kHz frequency range at the room temperature. Capacitance-voltage and capacitance-frequency
changes were investigated for the mixture. Threshold voltage was determined as 2.1 V. It was
seen that the capacitance suddenly damped at this voltage. Capacitance is large at lower frequencies
and small at higher frequencies than 100 kHz. The conductance-voltage change was obtained for the mixture. The conduction suddenly rose at the threshold voltage. The conduction is small at lower frequencies and large at higher
frequencies. Dielectric, birefringence index and splay elastic constant were investigated
for 6CB/8CB mixture. The measured values of the mixture are bigger than 6CB
values up to the certain frequency.

Authors: Yusubov Fikrat
Published: September 2018

Wear
mechanism of newly developed asbestos-free frictional materials (i.e. brake
pads material) was investigated by physical-mechanical experiments. The
suitability of the developed these new 
composite materials were investigaed by firiction testes at the different
temperatures. Thermal
investigation was performed by a differential scanning calorimetry (DSC) and
thermogravimetric analysis (TGA). Stability
and mechanical properties at different temperatures of the brake pad materials were
comparatively evaluated. Testing results showed that under the given
conditions, new developed frictional material has the advantages of the good
tribological properties over the widely used commercial asbestos enhanced
material as a FK-24A (Retinax, mark B). The research of the thermal and wear
behaviour of materials indicates that brake pair has better frictional
characteristics and wear resistance performance at high temperature. With
use of new friction brake pads materials will be improved the safety of braking
processes, and the quality in drilling will be increased. There is also an
environmental and economic advantages in using the new asbestos-free materials
in the break pads.

Published: September 2018

Kinetics, thermodynamics and isotherm studies of malachite
green (MG) adsorption by orange peel (OP) modified with ethanol, calcium chloride and sodium
hydroxide were
performed. Effects of initial dye concentration, temperature
and pH
on the adsorption were studied
at the different contact times. The amounts of MG adsorbed onto OP increased with increasing contact time, initial dye concentration, solution temperature, and pH. Maximum dye
adsorption was
about 92.90% under all
the experimental conditions.
Percent desorption of MG from the surface of OP was lower in the alkali and HCl
solutions and higher in an acetone-water mixture of 50%. Adsorption kinetics was best fit the pseudo-second
order model with correlation coefficients of 0.99 and 1 for the
concentrations studied. Thermodynamic results indicated a spontaneous
adsorption. Adsorption isotherm obeyed the Langmuir model. The Langmuir adsorption capacity was determined
as 14.55 mg g-1. FT-IR and SEM analyses were also recorded
before and after the adsorption.

Published: September 2018

Cyanobacterium samples were collected from fresh water of Tokat city in Turkey, and then isolation and cultivation of Chroococcus minutus were achieved successfully. TLC (Thin layer chromatography) and HPLC (High Performance Liquid Chromatography) analyses revealed that the C. minutus consisted of norharmane as a major product. So amount of norharmane was determined during the growth process. Growth and norharmane production of C. minutus were executed under salt stress and pH stress conditions. The most growth and the highest production of norharmane were detected at 16th day. Therefore inoculation process was performed at 16th day. Salt stress was evaluated at 0.5, 1.0, 3.0 and 5.0 M concentrations. The most norharmane was synthesized by C. minutus at 5 M concentration. The norharmane production and the growth were higher at pH 9 than that of the pH 5. Most norharmane was produced at pH 7.

A new Schiff base ligand
was synthesized from a reaction of 5-benzoyl-4-hydroxy-2-methyl-6-phenyl-2H-pyridazine-3-one
and 1,3-diaminopropane. Schiff base metal complexes
were synthesized from a reaction of Ni(AcO)2×4H2O, Cu(AcO)2×H2O, Co(AcO)2×4H2O, Pd(AcO)2
metal salts and ligand, respectively. 
All compounds were characterized using magnetic susceptibility,
elemental analysis, NMR (for ligand), UV-Vis and FT-IR spectroscopic analysis.
While octahedral structure has been proposed for Ni(II), Pd(II) and Co(II)
complexes, square-planar geometry is suggested for Cu(II) complex. Synthesized
compounds were evaluated for their antioxidant effect, DNA
cleavage and antimicrobial studies. The DPPH free radical scavenging activity
of compounds 1, 2, 3, 4 and 5 on DPPH were found as 38.5%, 32.5%, 36.9%, 35.7%
and 45.7% at 200 mg l-1, respectively.  The compounds 4 and 5 revealed maximum
ferrous chelating activity of 64.5% and 78.1% at 200 mg ml-1,
respectively. For all the compounds, DNA cleavage studies showed complete DNA
digestion at 100 mg ml-1. Antimicrobial activities of 3 and 4
complexes against Staphylococcus
aureus (ATTC 6538) were determined to be in 12 mm diameter.

Published: September 2018

The experiment was conducted to investigate the present status socio-economic and potentialities of buffalo production at Subornochar upazila of Noakhali district in Bangladesh. Data were collected from January to June 2014 through an interview schedule personally from 30 respondents in 6 villages of Subornochar upazila who were involved in buffalo production. All studied buffaloes were indigenous. All farmers used natural grass grown in plain land. About 7% farmers used mixed feed which was buying from local market and none used vitamin mineral supplementation. All farmers used natural breeding methods. About 40 and 67% farmers practiced vaccination and de-worming, respectively. About 27% farmers removed sick animals from healthy stock. Ninety five percent farmers allowed access to outdoor and pasturing and no farmers reared male and female buffalo separately. About 97% farmers did not keep livestock record and only 3% farmers kept their livestock record. Most of the farmers were middle aged categories (47%). Education level of farmers’ had no schooling (20%), primary (50%), secondary (20%), higher secondary (7%) and graduation (3%), respectively. The involvement of respondents in farming, business and government job were 80, 13 and 7%, respectively. Respondents used own capital, bank and NGO loan for buffalo production were 80, 13 and 7%, respectively. Lack of pasture land, technical knowledge, training facilities, unavailability fresh drinking water, higher cost for cowboy and parasitic infestation about buffalo production were 53, 80, 80, 30 ,50, and, 40%, respectively. There are great potentialities of buffalo production by improving socio-economic status in Bangladesh both for satisfying animal protein requirements and production of quality meat.Progressive Agriculture 29 (2): 158-167, 2018
Learning through multiple lenses: analysis of self, peer, nearpeer, and faculty assessments of a clinical history-taking task in Australia
Authors: Fitzgerald Kylie , Vaughan Brett
Published: September 2018

Purpose: Peer assessment provides a framework for developing expected skills and receiving feedback appropriate to the learner’s level. Near-peer (NP) assessment may elevate expectations and motivate learning. Feedback from peers and NPs may be a sustainable way to enhance student assessment feedback. This study analysed relationships among self, peer, NP, and faculty marking of an assessment and students’ attitudes towards marking by those various groups.Methods: A cross-sectional study design was used. Year 2 osteopathy students (n= 86) were invited to perform self and peer assessments of a clinical history-taking and communication skills assessment. NPs and faculty also marked the assessment. Year 2 students also completed a questionnaire on their attitudes to peer/NP marking. Descriptive statistics and the Spearman rho coefficient were used to evaluate relationships across marker groups.Results: Year 2 students (n= 9), NPs (n= 3), and faculty (n= 5) were recruited. Correlations between self and peer (r= 0.38) and self and faculty (r= 0.43) marks were moderate. A weak correlation was observed between self and NP marks (r= 0.25). Perceptions of peer and NP marking varied, with over half of the cohort suggesting that peer or NP assessments should not contribute to their grade.Conclusion: Framing peer and NP assessment as another feedback source may offer a sustainable method for enhancing feedback without overloading faculty resources. Multiple sources of feedback may assist in developing assessment literacy and calibrating students’ self-assessment capability. The small number of students recruited suggests some acceptability of peer and NP assessment; however, further work is required to increase its acceptability.
Univocity, Exhaustion and Failing Better: Reading Beckett with Disability Studies
Authors: Levin Yael
Published: September 2018

The emergence of theories of disability in the last decades has rendered figurative interpretation suspect; neglect of literal and material truths has been hailed unethical, the exercising of an ableist bias that utilizes physical impairment as a rhetorical device. Any attempt to reconcile such critical concerns with Beckett's writing must take cognizance of an essential incongruity between the socially conscripted theoretical framework and aesthetic experimentation, between a mimetic fidelity to lived experience and an art of non-relation. The essay suggests that Beckett's poetics of exhaustion and its rejection of substitution and analogy in the interpretation of figures allows us to think beyond the interdisciplinary divide. The body is not imagined as a stand-in or receptacle for philosophical ideas but rather as the substrate upon and with which these ideas evolve and change. The text maintains the materiality of mental and physical impairments at the same time that it loads them with a variety of different metonymical connections. Such a stylization of excess and accumulation serves to release disability from existing stereotypes and predetermined moral judgment. It does so while sidestepping an impasse in disability studies, between the need to valorise overcoming, on the one hand, and the need to support the inability to do so, on the other. Neither extolling the supercrip nor championing inability, Beckett allows his readers to productively imagine what it might mean to fail better.
