Outshine to Outbid: Weather-Induced Sentiment and the Housing Market
Authors: Hu Maggie Rong , Lee Adrian D.
Published: January 2020

This paper examines how sentiment affects homebuyers’ housing transaction decisions with a focus on auction sales. Utilizing housing transaction data in Sydney from 2000 to 2014, we find that transaction prices are significantly higher for auction sales compared with private sales, consistent with the notion of a “winner’s curse.” Four sentiment proxies, including three weather-based sentiment proxies and a survey-based sentiment index, are used to derive novel measures of sentiment, revealing that higher sentiment is associated with higher transaction prices, particularly for auction sales. Moreover, sentiment boosts sale prices particularly when the housing market is in boom; however, investors are not more prone to sentiment bias than are owner-occupiers. Sentiment exhibits an asymmetric effect in that low sentiment dampens price to a greater extent compared with the price-boosting effect of high sentiment. Our result is robust to using national sport events as sentiment shocks, selection bias, and participation constraints. Potential mechanisms include present-biased preferences and sentiment-related projection bias. Overall, our evidence sheds light on the role of sentiment in housing market decisions.

The Continuous-Time Inventory-Routing Problem
Authors: Lagos Felipe , Boland Natashia , Savelsbergh Martin
Published: January 2020

We consider a continuous-time variant of the inventory-routing problem in which the maximum quantity that can delivered to a customer depends on the customer’s storage capacity and product inventory at the time of the delivery. We investigate critical components of a dynamic discretization discovery algorithm and demonstrate in an extensive computational study that these components are sufficient to produce provably high-quality, often optimal solutions.

Authors: Louzán Mariño Rita
Published: January 2020

La evaluación de riesgos psicosociales de origen laboral constituye un fenómeno complejo y controvertido. Sus principales críticas están centradas en la validez de las herramientas que se emplean para la recogida de información, fundamentalmente autoinformes sensibles a diversas fuentes de error. Si bien se ha incrementado el esfuerzo por proporcionar evidencias sobre la fiabilidad y la validez de los instrumentos de evaluación disponibles, existen importantes fuentes de error, sesgos, que con frecuencia son ignoradas. La detección y control de sesgos es un tópico abordado desde varios ámbitos, entre ellos el de la psicología del trabajo, sin embargo, es desconocido por muchos técnicos de prevención de riesgos laborales. En este sentido, este artículo intenta acercar a los profesionales de la prevención de riesgos laborales, una mejor comprensión de este concepto, así como diversas técnicas para su identificación y control, en aras de mejorar la calidad de las evaluaciones de riesgo psicosocial.
Development of an autofocusing system using an electrically tunable lens in large area holographic lithography
Authors: Hou Rui , Yu Jia , Huang Yanyan , Ke Huaheng , Liu Huiping
Published: January 2020

Due to the limited processing accuracy of the platform and unevenness of the glass substrate itself, a holographic lithography system is prone to out-of-focus imaging problems; therefore, the real-time focusing components are critical for holographic lithography systems. In this paper, a real-time focus monitoring and adjusting system using an electrically tunable lens (ETL) for large-area lithography is introduced. Combined with the ETL, the limited depth of field of the microscopic objective has been effectively expanded, and the automatic focusing evaluation and adjustment are achieved. The development, including simulation using Zemax, optics system design and implementation, experiments, and evaluation are demonstrated in this paper. The results show that the out-of-focus problem in our large-area holographic lithography system has been significantly alleviated.
Optimized reconstruction with noise suppression for interferenceless coded aperture correlation holography
Authors: Liu Chao , Man Tianlong , Wan Yuhong
Published: January 2020

A modified nonlinear reconstruction technique with a noise modulation parameter is proposed for interferenceless coded aperture correlation holography (I-COACH), and thus the signal-to-noise ratio of a reconstructed image is improved without sacrifice of the field of view and temporal resolution of the system. In order to obtain the optimal reconstructed image, no-reference structural sharpness (NRSS) is introduced as the evaluation metric of reconstructed image quality during nonlinear reconstruction. On the other hand, the noise modulation function is built in order to analyze the effect of phase on noise when the amplitude of the point spread hologram and object hologram is unity of 1. Both the NRSS and noise modulation functions are combined with nonlinear reconstruction in I-COACH for improving imaging performance. The validities of the proposed method under different experimental conditions have been demonstrated by experiments.

, and PAN powder as main raw materials by wet spinning. The microstructure and spectral properties of the fiber were studied by means of scanning electron microscope (SEM), x-ray diffractometer (XRD), and a fluorescence spectrophotometer. The results showed that the two rare-Earth luminous materials were randomly dispersed on the interior and surface of the fiber. Due to the spinning process, the luminescent materials were agglomerated in fiber, and there were many voids in the fiber. Compared with pure rare-Earth luminous materials, the emission wavelength of the spectrum-fingerprint anti-counterfeiting fiber has no obvious shift, but the addition proportion and amount of two rare-Earth luminous materials have great influence on the spectral curve of the fiber. This fiber with two luminous centers maintains the basic characteristics of spectrum-fingerprint anti-counterfeiting fiber and is a new, to the best of our knowledge, type of anti-counterfeiting fiber with high anti-counterfeiting application potential.

Authors: Ding Zihao , Xu Hui , Chen Guodong , Wang Zheng , Chi Wenzheng , Zhang Heng , Wang Zhenhua , Sun Lining , Yang Guilin , Wen Yifang
Published: January 2020

With the prevailing application of new materials and the higher
requirements for the quality and efficiency of production in the
equipment manufacturing industry, traditional assembly methods can
hardly meet the needs of large-scale production, especially in the
field of high-precision assembly. Robot assembly guided by visual
perception has become the key of the research in the field of
engineering technology. It requires higher accuracy of robot visual
perception and the control over force, position and so on. However, in
3C assembly, most products are made of transparent materials such as
glass. Because of the transparency and specular reflection of the
surface, 3D reconstruction of transparent objects is a very difficult
problem in computer vision, in that the traditional visual perception
methods could not be accurate enough. The present research proposes a
bionic active sensing algorithm for 3D perception and reconstruction
and realizes high-precision 3D by applying the registration algorithm.
The purpose is to solve the problems existing in the traditional
visual perception method, such as difficulties in achieving active
sensing, low accuracy of point clouds registration, and complex
computation. The results of the experiments show that the present
method is efficient and accurate in 3D reconstruction. It reduces the
planar reconstruction error to 0.064 mm and the surface reconstruction
error to 0.177 mm.

Authors: Onyeanu Chika ThankGod , Ezenduka Ekene Vivienne , Anaga Aruh Ottah
Published: January 2020

Background and Aim: Gentamicin is a broad-spectrum antimicrobial used in the treatment of a variety of bacterial infections in poultry, its residue in tissues is known to have a deleterious effect in man when consumed. The study aimed to determine the use of gentamicin by poultry farmers and the presence and occurrence of gentamicin residue in tissues of commercial broilers in Ikpa slaughterhouse Nsukka. Materials and Methods: The study adopted a cross-sectional survey using questionnaire and immunological screening. A total of 108 broilers were sampled, testing 108 each of muscle, liver, and kidney tissues for gentamicin residue using enzyme-linked immunosorbent assay. Results: The questionnaire survey revealed that in the management practices, 55.2% of the farms used intensive deep litter, 21% intensive battery cage, and 23.6% extensive farming system. Twenty-seven (71%) farms reared only broilers, 10.5% layers, and 18.4% both. The feeding management showed that 21.1% of farmers produced their own feed (medicated) while 78.8% used commercial feed, of which 11.5% incorporated antibiotics. Hundred (100%) of the respondents used gentamicin and only 47.3% were aware of the consequences of antimicrobial residue in foods of animal origin, with knowledge of the legislation on the prudent use of antimicrobials in food animals. The occurrence of gentamicin residue in surveyed birds was 65% with tissue distribution as follows: Muscle (44.4%), liver (51.9%), and kidney (59.3%). Conclusion: Poultry farms in the study area make constant use of gentamicin without observing its withdrawal period before sale, and a high percentage of the commercial birds meant for human consumption contains gentamicin residue. Therefore, consumers might be at risk of consuming gentamicin as a parent drug or its metabolites in commercial poultry.

Published: January 2020

This scientific article contains results of research the two layers cardboard`s cross-section produced by ion beam cutting technology with converting of cross-section image by computer programs. The cross-section of two layers cardboard`s which produced by traditional wet method and aerodynamic forming method was presented to compare. The bottom layer was obtained by the traditional wet method from old corrugated cardboard recovered paper and the top layer was obtained by aerodynamic forming method from print recovered paper. The boundary layers, cut fibers, fibrils, additives, porous area, and lines of contact fibers for the each layer and the contact line of the fiber walls were determined with converting and analyzing of cross-section image by computer programs. The developed method made it possible to separate lines of contact fibers which determine the emergence of inter fiber bonds from the contact line of the fiber walls. The comparison of the results allowed explaining in a new way the decrease in mechanical parameters of cardboard during dry preparation of recovered paper. The ion beam cutting technology with converting of cross-section image by computer programs allowed determining cut fibers area and porous area. This made it possible to quantify the effect of fiber distribution factors on the mechanical property of cardboard. The content of the additive (calcium carbonate) and its distribution in layers is estimated by the spectrum of the elemental composition.

Published: January 2020

The fatty acid comparative essay of high aquatic plants: Typha latifolia L., Ceratophyllum demersum L. and Veronica anagallis-aquatica L. from water bodies of Baikalian region was carried out. For the first time this biochemical parameter of water form V. anagallis-aquatica was compared with that of coastal-water T. latifolia and submerged C. demersum. The fifteen individual molecules of fatty acids with a chain length from 12 to 22 carbon atoms have been identified by the method of gas liquid chromatography – mass spectrometry. The fatty acid composition of investigated species was different. Among the fatty acids saturated and unsaturated molecules was found, the most distributed fatty acids was saturated palmitic (С16:0), steric (С18:0) and unsaturated linoleic (С18:2 w6), α-linolenic (С18:3 w3). In total, the C16 and C18 acids in studied species accounted for 98%. Differences in the composition of fatty acids of the studied species are discussed from the standpoint of the characteristics of fatty acid metabolism depending on the habitat of plants and are considered as one of the mechanisms of their adaptation to late vegetation. Studies of the fatty acid composition of aquatic organisms contribute to the overall strategy of plant adaptation to changing environmental conditions and are important for the ecological and biochemical monitoring of the ecological status of water bodies.

Published: January 2020

Micromorphological and chemical analyses of the leaves of soft wheat hybrids, differing in susceptibility to brown rust damage (pathogen Puccinia triticina Erikss.), were carried out. In this work we studied F4 progeny samples obtained by crossing the Novosibirsk 9 common wheat variety with Chinese Spring null-tetrasome lines, with differences in the CAD isozymes pattern and affected by fungal infection by 10–20, 30 and 70%. The leaves of typical plants of each genotype that were not exposed to infection were analyzed. The ratio of inorganic substances – potassium and calcium salts, and biogenic silicon oxide – was determined both on the surfaces of the leaves and in there total biomass. It is established that silicon oxide, which prevails on the surface of the leaves, increases resistance to fungal infection. Based on TGA, the lignin structure of leaves affected by brown rust is uniform. Lignin of the leaves of the resistant genotypes has several fractions that differ in their thermal properties. The content of glycosides of apigenin and aromatic acids is higher in the leaves of resistant genotypes. The leaves of plants susceptible to fungal infection contain less chlorophyll b, which could cause a delay in growing and flowering and weaken the protective reactions of plants.

Published: January 2020

Black Soldier Fly are natural antibiotics. It is expected that the use of BSF larvae in poultry rations as an alternative source of conventional protein will contribute to improving the immune status and maintaining animal health, thereby reducing the use of antibiotic growth promoters (AGPs). This study aimed to evaluate the effect of the best type of BSF protein for determining the health status of laying hens based on the activity and capacity of macrophage phagocytosis on the non-protein A bacterium Staphyllococcus aureus. Results of this study indicated that the BSF extract (P3) has the highest phagocytic capacity value. This result proves that the BSF extract can induce macrophage cells to optimally process bacterial cells or foreign phagocyte particles. The highest average activity value, and phagocytic capacity of peritoneal macrophages was resulted from BSF extract (P3), respectively was 91.34 ± 0.38% and 22.84 macrophage-1 bacteria.
Participação social e gestão ambiental: uma análise do conselho gestor do Parque Estadual da Serra do Brigadeiro, Minas Gerais - Brasil
Authors: Magno Lucas
Published: January 2020

O processo de redemocratização brasileiro engendrou diversas experiências de gestão participativa em distintos setores. Na esfera ambiental, por exemplo, a criação de conselhos gestores de Unidades de Conservação (UC) foi uma destas experiências que trouxe avanço político e social no que conserne à sustentabilidade e à gestão democrática destes territórios. Nesse contexto, o artigo analisa a constituição e o funcionamento de um conselho gestor de uma UC no estado de Minas Gerais que é tido como um dos mais participatidos, qual seja: o conselho consultivo do Parque Estadual da Serra do Brigadeiro (PESB). Operacionalizamos metodologicamente o trabalho com a observação participante nas reuniões deste conselho e com análises documentais. Como resultados, argumentamos que um dos elementos que fazem com que o conselho do PESB seja participativo diz respeito ao próprio processo de implementação desta UC, primeira de Minas Gerais criada de forma participativa; e que a existência prévia de processos mobilizatórios na região levaram ao envolvendo da sociedade civil na construção e implementação do conselho consultivo do PESB, estruturando o mesmo em termos de representatividade e paridade política. Evidentemente que isso não se deu sem conflitos, mas, de maneira geral, argumentamos que este conselho tem garantindo a pluralidade social no que tange à representação da sociedade civil e assegurando processos democráticos na gestão ambiental.

Published: January 2020

The gist of this study was to explore language as a tool for religious leaders in preventing and countering radicalisation and religious extremism among the youth.  This study emphasised on language an indispensable tool that religious leaders can use in curbing this recruitment which has claimed lives and has had economic repercussions. The study specifically assessed the collaboration between the Government of Kenya (GoK) and religious leaders in Eastleigh towards countering radicalisation and religious extremism among the youth and it proposes a common discourse that religious leaders could use in preventing radicalisation and religious extremism of the youth. The study was anchored by the Social Movement Theory (SMT). The target population comprised of the religious leaders, security operatives and youths in Eastleigh. The study implored simple random sampling technique. In total a sample of 100 respondents were randomly selected from the study site. The researchers collected primary data from the respondents by administering questionnaires (to the youth) and interview schedules on religious leaders and the security personnel. The data was analysed using quantitative and qualitative techniques. Quantitative data was analysed using Statistical Package for Social Sciences (SPSS) version 23 program while qualitative was analysed through narrative descriptions. The study findings established that among many other tools and means, language is key in curbing youth radicalisation and religious extremism. It also revealed that the Government of Kenya should directly engage the religious leaders on matters prevention of youth radicalization and religious extremism. The youth bemoaned lack of employment and political participation as the factors that pull them to radicalisation and religious extremism. They also want to be fully engaged in occasions where language is used between the GoK and Religious leaders.
From EFL classroom language to classroom lexicon: Importing formulaic story language into teacher talk
Authors: MASONI LICIA
Published: January 2020

This paper reports on a language activity carried out in an Italian University with student teachers attending a primary education course. The activity was designed to train them to use authentic children’s picturebooks as a source for EFL language learning. It consisted of identifying and ‘noticing’ (Mackey 2006) multiword expressions and ready-made utterances in a number of authentic picturebooks and simulating instances of weaving the picturebook language into the fabric of daily classroom talk. Following the activity, the students wrote individual pieces of reflective writing describing their experience. Comments by student teachers assessed the use of picturebook-derived formulaic language on both their learning and perceived ability to teach English, and revealed much about their pedagogical perspectives on teacher talk. Results suggest that promoting the use of authentic and meaningful language in context can help student teachers conceive of classroom communication as lexicon (a shared communicative practice the rules of which are fully known only by a restricted community of speakers) rather than mere language-based interaction

The Dual Baer Criterion for non-perfect rings
Authors: Trlifaj Jan
Published: January 2020

Baer’s Criterion for Injectivity is a useful tool of the theory of modules.
Its dual version (DBC) is known to hold for all right perfect rings, but its validity for the non-right perfect ones is a complex problem (first formulated by C. Faith
[Algebra. II. Ring Theory,
Springer, Berlin, 1976]).
Recently, it has turned out that there are two classes of non-right perfect rings:
(1) those for which DBC fails in ZFC, and
(2) those for which DBC is independent of ZFC.
First examples of rings in the latter class were constructed in
[J. Trlifaj,
Faith’s problem on R-projectivity is undecidable,
Proc. Amer. Math. Soc. 147 2019, 2, 497–504];
here, we show that this class contains all small semiartinian von Neumann regular rings with primitive factors artinian.
Recovery of non-smooth radiative coefficient from nonlocal observation by diffusion system
Authors: Zhang Mengmeng , Liu Jijun
Published: January 2020

The heat conduction process in composite medium can be modeled by a parabolic equation with discontinuous radiative coefficient.
To detect the composite medium characterized by such a non-smooth coefficient from measurable information about the heat distribution, we consider a nonlinear inverse problem for parabolic equation, with the average measurement of temperature field in some time interval as the inversion input.
We firstly establish the uniqueness for this nonlinear inverse problem, based on the property of the direct problem and the known uniqueness result for linear inverse source problem.
To solve the inverse problem from a nonlinear operator equation, the differentiability and the tangential condition of this nonlinear map is analyzed.
An iterative process called two-point gradient method is proposed by minimizing data-fit term and the penalty term alternatively, with rigorous convergence analysis in terms of the tangential condition.
Numerical simulations are presented to illustrate the effectiveness of the proposed method.

Authors: Salta Zoi , Kosmas Agnie M. , Ventura Oscar N.
Published: January 2020

Electronic structure calculations have been performed to determine the thermochemistry and kinetics of the reaction between OH and the radicals of the S enantiomer of the herbicide Metolachlor, 2-chloro-N-(2-methyl-6-ethylphenyl)-N(2-methoxy-1-methylethyl) acetamide (MC), produced by photoinduced breaking of the C–Cl bond. Both density functional and ab initio composite methods were employed to calculate the structure of reactants, intermediates, transition states and products, in gas phase and in aqueous solution. The expected relative abundance of each product was calculated and compared to the experimentally observed concentrations. It is shown that a combination of thermodynamic and kinetic characteristics interplay to produce the expected theoretical abundances, which turn out to be in agreement with the experimentally observed distribution of products.

Authors: Feizi Rozhan , Jaafarzadeh Nematollah , Akbari Hamideh , Jorfi Sahand
Published: January 2020

Background: The aim of this study was to determine the concentrations of lead (Pb) and cadmium (Cd) in lipstick and eye pencil cosmetics of different grades in the markets of Iran. Methods: This descriptive study was conducted in Ahvaz city in 2018. Sixty different samples of lipstick and eye pencil of three common brands were selected and analyzed using the Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-OES) and the results were compared with standard values recommended by the Food and Drug Administration (FDA). The analysis of lipsticks was based on producer country and colors and producer country only for eye pencil. Results: The mean concentrations of Pb and Cd were 41.86 and 53.42 µg/g, respectively. Concentrations of lead were higher than those of Cd in lipsticks, while for eye pencil, Cd showed higher concentrations. The overall results indicated that in all brands and colors of lipsticks, only 33% of the samples had Pb content less than the FDA limit, and among lipstick samples, 44% had Cd concentration less than the FDA limit of 3 μg/g, however, in 100% of the eye pencil samples, the concentration of Cd was higher than the recommended value of 3 μg/g. Conclusion: Given the health risks of exposure to heavy metals and in order to increase community awareness about the harmful effects of cosmetics, it is necessary to monitor the concentration of these toxic elements in these products and encourage the manufactures to meet the FDA standards.
Comparative Surface Morphology of Machined Hybrid and Unhybrid Zinc-Aluminum Alloy-Based Metal Matrix Composites
Authors: Marigoudar Rajaneesh N.
Published: January 2020

The present article reveals the surface characteristics of zinc-aluminum alloy (ZA43) reinforced with silicon carbide (SiC) particulate conventional composite and SiC+Graphite dual reinforced hybrid metal matrix composites. Both the composites were prepared using a liquid metallurgy technique. A base alloy of metal matrix composites (MMC) containing zinc—57 %, aluminum—43 % was reinforced with SiC (5 %) with an average particle size of 60 μm and hybrid composite with 5 % SiC and 5 % graphite. The coated carbide tool SNMG was used to machine the two varieties of composites under dry condition. Machining parameters were considered at three different levels, keeping a constant depth of cut. It was observed from the results that the surface finish was greatly influenced by cutting speed and feed. Unhybridized composites exhibit (without graphite) higher roughness values than composites with graphite during the machining trials. The reasons for higher roughness values include particle pullout, particle fracture, and built-up edge formation on the cutting tool during the machining process.
Isolation, Kinetics, and Performance of a Novel Phenol Degrading Strain
Authors: Zhang Wen , Xia X.
Published: January 2020

Efficient phenol-degrading bacteria is still the key to the biological treatment of phenol-containing wastewater. In this research, a novel phenol-degrading strain N8 was isolated. According to the 16S rDNA identification, it was concluded that the N8 strain was Bacillus sp. IARI-J-20. The wastewater treatment experiments showed that the phenol degrading rate of N8 reached 92.8 % at 24 h with the inoculation amount of 15 %, temperature of 30 °C, pH of 7.2, yeast extract addition of 0.08 %, and initial phenol concentration of 225 mg L–1. Haldane’s model was fit for the growth kinetics of the phenol-degrading strain N8 over a wide range of initial phenol concentrations (50–1200 mg L–1), with kinetic values μmax = 0.33 h−1, Ks = 79.16 mg L–1, and Ki = 122 mg L–1. The yield coefficient reached maximal value when the phenol concentration was 400 mg L–1. When the initial phenol concentration was more than 400 mg L–1, the inhibition effect of phenol became predominant.

Authors: Keskin Tugba
Published: January 2020

In this study, novel and conventional techniques for the production of bioethanol from fruit and vegetable wastes (FVWs) by yeast and bacterial fermentation were investigated experimentally. Different pretreatment techniques (acid, heat, acid/heat, and microwave) for yeast fermentation were compared. Maximum ethanol concentrations of 11.7 and 11.8 g L–1 were observed from acid/heat and microwave pretreatment, respectively, by using Saccharomyces cerevisiae. On the other hand, biochar production from FVWs and syngas fermentation from the waste gas of this process were integrated. From waste gas with 12 % CO content, 5.5 g L–1 and 2.5 g L–1 ethanol production was observed by using anaerobic mixed culture and Clostridium ljungdahlii, respectively. The overall results emphasize the potential of bioethanol production from FVWs by economically feasible and environmentally friendly methods.

Published: January 2020

Glucocorticoid (GC) signaling via the glucocorticoid receptor (GR) is essential for lung maturation in mammals. Previous studies using global or conditional mouse model knockouts of the GR gene have established that GR-mediated signaling in the interstitial mesenchyme of the fetal lung is critical for normal lung development. Screens for downstream GC-targets in conditional mesenchymal GR deficient mouse lung (GRmesKO) identified Versican (Vcan), an important extracellular matrix component and cell proliferation regulator, as a potential GR-regulated target. We show that, of the five major VCAN isoforms, the VCAN-V1 isoform containing the GAGβ domain is the predominant VCAN isoform in the fetal mouse lung distal mesenchyme at both E16.5 and E18.5, whereas the GAGα-specific VCAN-V2 isoform was only localized to the smooth muscle surrounding proximal airways. Both Vcan-V1 mRNA and protein levels were strongly overexpressed in the GRmesKO lung at E18.5. Finally, we investigated the GC regulation of the ECM protease ADAMTS 12 and showed that Adamts 12 mRNA levels were markedly reduced at E18.5 in GRmesKO fetal mouse lung and were strongly induced by both cortisol and betamethasone in cultures of primary rat fetal lung fibroblasts. ADAMTS12 protein immunoreactivity was also strongly increased in the distal lung at E18.5, after dexamethasone treatment in utero. In summary, glucocorticoid signaling via GR represses GAGβ domain-containing VCAN isoforms in distal lung mesenchyme in vivo by repressing Vcan gene expression and, in part, by inducing the ECM protease ADAMTS12, thereby contributing to the control of ECM remodelling and lung cell proliferation prior to birth.

To investigate the role of microRNA (miRNA) in muscle atrophy, we performed microarray analysis of miRNA expression in skeletal muscles of Sham, orchiectomized (ORX) mice, and ORX mice treated with androgen and identified that the expression of miR-23b-3p in ORX mice was significantly higher than that in Sham mice (P = 0.007); however, miR-23b-3p expression in ORX mice treated with androgen was lower (P = 0.001). We also investigated the mechanism by which overexpression or knockdown of miR-23b-3p influences the expression of myosin heavy chain, muscle protein synthesis, ATP activity, and glucose uptake in C2C12 myotube cells. Moreover, we examined the serum miR-23b-3p levels among male subjects with type 2 diabetes and whether the serum miR-23b-3p levels could be a biomarker for muscle atrophy. The overexpression of miR-23b-3p in C2C12 myotube cells significantly upregulated the expression of myosin heavy chain, protein synthesis, ATP activity, and glucose uptake. Reporter assays raised a possible direct post-transcriptional regulation involving miR-23b-3p and the 3′-UTR of PTEN mRNA. Among subjects with type 2 diabetes, serum miR-23b-3p levels in the subjects with decreased muscle mass were significantly higher compared to the levels in the subjects without. Our results indicate that miR-23b-3p downregulates the expression of PTEN in myotube cells and induces the growth of myosin heavy chain. In addition, the serum level of miR-23b-3p can be used as a diagnostic marker for muscle atrophy.

Intraflagellar transport (IFT) is a conserved mechanism essential for the assembly and maintenance of most eukaryotic cilia and flagella. IFT172 is a component of the IFT complex. Global disruption of mouse Ift172 gene caused typical phenotypes of ciliopathy. Mouse Ift172 gene appears to translate two major proteins; the full-length protein is highly expressed in the tissues enriched in cilia, and the smaller 130 kDa one is only abundant in the testis. In male germ cells, IFT172 is highly expressed in the manchette of elongating spermatids. A germ cell-specific Ift172 mutant mice were generated, and the mutant mice did not show gross abnormalities. There was no difference in testis/body weight between the control and mutant mice, but more than half of the adult homozygous mutant males were infertile and associated with abnormally developed germ cells in the spermiogenesis phase. The cauda epididymides in mutant mice contained less developed sperm that showed significantly reduced motility, and these sperm had multiple defects in ultrastructure and bent tails. In the mutant mice, testicular expression levels of some IFT components, including IFT20, IFT27, IFT74, IFT81 and IFT140, and a central apparatus protein SPAG16L were not changed. However, expression levels of ODF2, a component of the outer dense fiber, and AKAP4, a component of fibrous sheath, and two IFT components IFT25 and IFT57 were dramatically reduced. Our findings demonstrate that IFT172 is essential for normal male fertility and spermiogenesis in mice, probably by modulating specific IFT proteins and transporting/assembling unique accessory structural proteins into spermatozoa.

Estudos têm mostrado o potencial dos videogames para treinar habilidades cognitivas. O presente estudo verificou a eficácia de um treinamento com jogos eletrônicos para melhoria das funções cognitivas de atenção e memória de estudantes universitários. Participaram da pesquisa 25 universitários, com idade entre 18 e 29 anos, de ambos os sexos. Utilizou-se os testes de Trilhas, Nomeação de Boston, Lista de Palavras, Subteste dígitos das Escalas Wechsler de Avaliação de Inteligência Adulta, Teste do Desenho do Relógio, Fluência Verbal: Animais e Questionário de Queixa Subjetiva de Memória. O treinamento com jogos eletrônicos utilizou jogos comerciais, escolhidos pela equipe de pesquisa. O treino durou entre 5 e 16 semanas, com tempo progressivo de treinamento variando de 20 a 60 minutos. Os participantes eram equivalentes nas funções cognitivas no pré-teste. Após a intervenção, foram observadas diferenças na memória imediata, memória tardia, reconhecimento, recordação de dígitos em ordem inversa, atenção e nomeação. Os resultados indicam que os jogos eletrônicos podem ser ferramentas úteis para treinar as habilidades cognitivas, mas como a amostra é pequena, estudos futuros são necessários para ampliar os conhecimentos na área.

Published: January 2020

O objetivo deste estudo foi investigar a interface entre cognição social e linguagem, analisando as relações entre a teoria da mente e a pragmática da linguagem em crianças com Transtorno do Espectro Autista (TEA). Participaram da pesquisa 24 crianças com TEA, entre 6 e 12 anos de idade. Para a avaliação das habilidades sociocognitivas foram utilizadas tarefas da escala de teoria da mente e, para a avaliação da pragmática, um instrumento de compreensão de enunciados literais e não literais (avaliados nas subcategorias: implicaturas conversacionais e expressões idiomáticas). Os resultados indicaram que: 1) as crianças manifestaram compreensão da linguagem literal significativamente superior à compreensão das implicaturas conversacionais e das expressões idiomáticas; e 2) que as crianças que acertaram as tarefas de falsa crença foram as que tiveram um desempenho melhor nos enunciados não literais de expressões idiomáticas. Esses achados dão suporte à hipótese de associação positiva entre compreensão da falsa crença e pragmática.

Este estudo teve o objetivo de testar o poder preditivo dos cinco grandes fatores de personalidade, da influência interpessoal e de variáveis sociodemográficas sobre a compra por impulso. Participaram do estudo 1.296 brasileiros, média de idade de 35,8 anos (DP = 12,8), escolaridade mínima de Ensino Médio incompleto. Os resultados mostraram relações da compra por impulso com variáveis sociodemográficas, hábitos de consumo e personalidade. O modelo de regressão explicou 23% da variância da compra por impulso, sendo os maiores poderes preditivos o da influência interpessoal normativa e o do fator de personalidade neuroticismo, ambos preditores positivos; seguidos do hábito de fazer lista de compra e do fator conscienciosidade, como negativos. Os resultados confirmam o poder preditivo de fatores de personalidade, hábitos de consumo e variáveis sociodemográficas sobre o comportamento de compra por impulso.

The poetry of Bartłomiej Majzel: a psychoanalytic approach
Authors: Jurzysta Marcin
Published: January 2020

Bartłomiej Majzel is one of the most interesting young polish authors. His first poetic book is robaczywość [worminess] published in 1997. As regards interpretation, many motifs which recur in the volume, suggest a psychoanalytic approach. This approach reveals a dark world of sub-consciousness and transcription of struggling against oneself, reporting the consequences of this tragic party called literature.
Identity as a narrative of autobiography
Authors: Jakubowska Luba
Published: January 2020

This article is a proposal of identity research through its process and narrative character. As a starting point I present a definition of identity understood as the whole life process of finding identification. Next I present my own model of auto/biography-narrative research inspired by hermeneutic and phenomenological traditions of thinking about experiencing reality. I treat auto/biography-narrative research as a means of exploratory conduct, based on the narrator’s biography data, also considering the researcher’s autobiographical thought. In the final part of the article I focus on showing the narrative structure of identity and autobiography. I emphasise this relation in definitions qualifying autobiography as written life narration and identity as a narration of autobiography.
