Mediación del compromiso afectivo entre las prácticas de gestión humana y las conductas de ciudadanía organizacional en jefes colombianos

El objetivo fue identificar si el Compromiso Afectivo (CA) media la relación entre las Prácticas de Gestión Humana (PGH) y las Conductas de Ciudadanía Organizacional (CCO) en una muestra de jefes colombianos. Estudios refieren que las PGH tienen impacto en el compromiso, y este, a su vez, en el desempeño, pero hay menor producción científica sobre el papel mediador del compromiso entre las variables. El estudio fue cuantitativo, no experimental y transversal. Se trabajó con 1037 jefes de 13 empresas colombianas de distintos sectores. Los hallazgos confirman que el CA media entre las PGH y las CCO. Cuando los empleados perciben existencia, calidad y cobertura de las PGH, ello impacta positivamente su vinculación afectiva con la organización y, a su vez, desarrollan mayores conductas en beneficio de esta y de sus compañeros de trabajo, sin que dichos comportamientos se encuentren previamente definidos en su cargo.
A novel parallel nanomixer for high-throughput single-molecule fluorescence detection

This paper introduces a novel fluidic device based on syringe-driven flow of fluorescent species through a parallel array of nanochannels, in which the geometrical confinement enables long observation times of non-immobilized molecules. Extremely low flow rates are achieved by operating the array of nanochannels in parallel with a larger microchannel. The addition of a second microfluidic inlet allows for mixing different species in a well-defined volume, enabling the study of irreversible reactions such as DNA synthesis in real-time using single-molecule fluorescence resonance energy transfer. Devices are fabricated in glass with the purpose of high-throughput single-molecule fluorescence detection.
Maíz para silo de planta entera: efecto de genotipo y altura de corte en la producción y calidad para alimentación animal

espanolEl objetivo de esta investigacion es evaluar el efecto de genotipo y altura de corte del maiz en la produccion y calidad para alimentacion animal. Para evaluar tanto los materiales geneticos como el uso de ensilaje de plantas enteras se utilizaron dos hibridos de maiz (SYN 126 y SYN 139) picados a dos alturas de corte y ensilaje durante 30 dias en micro silo. SYN 126 mostro mas rendimiento de grano y rendimiento de silo. SYN 139 mostro una mayor digestibilidad de la materia seca y energia metabolizable. Sin embargo, la altura de corte no mostro diferencias significativas. En conclusion, el hibrido SYN 126 mostro mejor comportamiento agronomico y el hibrido SYN 139 mostro una mejor calidad nutricional. Tambien se concluye que la decision de la altura de corte deberia pasar por la importancia de la necesidad de dejar mayor cantidad de rastrojos en el sistema productivo EnglishThe main objective of this research study is to assess the effect of maize genotype and cutting height on the production and quality of livestock feed. In order to evaluate both the genetic materials and the use of whole plant silage, two maize hybrids (SYN 126 and SYN 139) were chopped at two cutting heights and were silage during 30 days in micro silo. SYN 126 showed higher grain and silo yield. SYN 139 showed greater dry matter digestibility and metabolizable energy. However, cutting height showed no significant differences. In conclusion, the hybrid SYN 126 had greater agronomic performance and the hybrid SYN 139 had better nutritional quality. In addition, the decision-making process on cutting heights should be examined based on the importance of the need for leaving greater amounts of stubble in the productive system.

Given the challenges in detection of fake news, many researchers are trying to understand the problem statement and its characteristics. In this paper, the existing approaches and the new methods proposed by researchers have been summarized. The methods vary according to the content types (textual or image based) so that problem can be tackled in a better way and improved classification results can be obtained.
A Rapid Recognition Method for Rice False Smut based on HOG Features and SVM Classification

A rapid detection method for the detection of false smut is introduced based on HOG features and SVM classification to overcome the drawbacks of false smut detection like time wasting and inaccurate recognition. In this paper, original images of false smut used, which directly taken from the field of rice. First of all, the image false smut diseased rice acquired by image preprocessing was based on the color threshold to obtain the (ROI) region of interest from healthy and unhealthy pictures of rice. Secondly, the gamma-correction performed on the extracted ROI unhealthy and background region of healthy rice images. The HOG features extracted to form a high-dimensional HOG feature vector. Third, the PCA analysis performed on high-dimensional HOG features, and the original 1764-dimensional feature vector reduced to a two-dimensional vector that can represent most vectors to achieve the purpose of dimension reduction. Finally, the dimension-reduced HOG feature vector sent to the SVM classifier for training. The expected recognition accuracy under the binomial kernel function is 80.6%, and the actual test set recognition is 78.56%.

Preparation and Characterization of Magnetic Banana Peels Biochar for Fenton Degradation of Methylene Blue

Co-precipitation method was used for the synthesis of biochar/Fe3O4 to heterogeneously degrade methylene blue (MB) in an aqueous medium. This catalyst was characterized by different techniques such as Fourier Transform Infrared (FTIR) Spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and Raman Microscopy. The analysis highlighted the presence of iron oxides on the surface of the biochar in the form of magnetite (Fe3O4). Catalytic tests performed on this composite showed significant degradation and simple magnetic separation in the solution for reuse. Maximum degradation was carried out after stirring it for 90 minutes in an MB aqueous solution at different concentrations. The percentages of degradation were 99% and 98.6% 93.3% and 91% for concentrations of MB 40 mg/L and 60 mg/L, 80 mg/L and 120 mg/L respectively. The reactions followed a second-order kinetics with correlation coefficients r2 = 0.9598, 0.9247, 0.9548 and 0.9614 for the same concentrations of MB at pH = 2, 0.2 mL/L H2O2 and 15 mg of biochar/Fe3O4. This work provides a simple and an effective method for the preparation of biochar/Fe3O4 and its use for the oxidation of MB by means of heterogeneous Fenton.
Ant behaviour and brain gene expression of defending hosts depend on the ecological success of the intruding social parasite

The geographical mosaic theory of coevolution predicts that species interactions vary between locales. Depending on who leads the coevolutionary arms race, the effectivity of parasite attack or host defence strategies will explain parasite prevalence. Here, we compare behaviour and brain transcriptomes of Temnothorax longispinosus ant workers when defending their nest against an invading social parasite, the slavemaking ant Temnothorax americanus. A full-factorial design allowed us to test whether behaviour and gene expression are linked to parasite pressure on host populations or to the ecological success of parasite populations. Albeit host defences had been shown before to covary with local parasite pressure, we found parasite success to be much more important. Our chemical and behavioural analyses revealed that parasites from high prevalence sites carry lower concentrations of recognition cues and are less often attacked by hosts. This link was further supported by gene expression analysis. Our study reveals that host–parasite interactions are strongly influenced by social parasite strategies, so that variation in parasite prevalence is determined by parasite traits rather than the efficacy of host defence. Gene functions associated with parasite success indicated strong neuronal responses in hosts, including long-term changes in gene regulation, indicating an enduring impact of parasites on host behaviour. This article is part of the theme issue ‘The coevolutionary biology of brood parasitism: from mechanism to pattern’.
Vertical-Array-based Contour Reconstruction Algorithm for Airborne Weather Radar

Aiming at meteorological target, in this paper, a new contour reconstruction algorithm is proposed against the disastrous weather. The algorithm is capable of reconstructing the specific contour of meteorological target by exploiting vertical array of airborne weather radar system. First of all, Burg algorithm is utilized for the enhancement of beam spatial resolution in elevation dimension. Then, multi-beam algorithm is employed to form multiple beams and generate multiangle echoes, which further obtains more vertical contour information about weather scenario. Consequently the proposed algorithm, combining Burg algorithm and multi-beam algorithm, distinctly retrieves the vertical contour information and delivers a super-resolution behavior simultaneously. Using simulated radar data, the processing results demonstrate the validity of the presented algorithm. Compared with the so-called interpolation-based conventional methods, the proposed algorithm can achieve more comprehensive and accurate vertical contour reconstruction.
Plant Leaf Disease Identification by Deep Convolutional Autoencoder as a Feature Extraction Approach

A healthy plant is needed to provide good quality of food which is important to daily life. However, plant diseases have a major impact on agricultural production and economy. Conventional approach is mainly based on hand labor experiences of farmers leading to that it may have adverse consequences in preventing disease transmission. Various techniques have been applied to identify the disease in plant in order to provide solutions to the farmers as well as send them a warning signal. This paper proposes a method for plant disease identification through a set of collection of leaf images. This method is developed based on a deep convolutional autoencoder approach. Original images are firstly reconstructed by the autoencoder and then by using only encoder part, the features of these images are extracted. The output features are fed into Support Vector Machine for classification. A small set of Plant Village dataset is considered to verify the performance of the reconstructed performance by the convolutional autoencoder. Then, for the classification stage, simulation results obtained have shown that the difference of autoencoder architecture and kernels of classifier give different average accuracy. Thus, the highest accuracy reached 98.8% for plant disease classification.
Comparative study of lithium ion hybrid super capacitors

A relative newcomer to the energy storage market, the Lithium Ion Hybrid Super Capacitor is a novel technology breaking new ground in the technology sector. The (LIC) or (LIHC) is fast evolving as the missing link between the Electric Double Layer Capacitor (EDLC) and the Lithium Ion Battery (LIB), being a distinct hybrid of the two technologies. The LIHC combines both energy and power with far longer life and safety features. The use of LIHC capacitors has already woven itself into many industry applications including but not limited to hybrid vehicles, remote area charging solutions, energy harvesting and storage and communications technologies. Mass deployment of LIHCs seems inevitable given the uptake in design processes with the pros outweighing the cons and with higher volume production increasing rapidly. In this paper we will model the Lithium Ion Capacitor characteristics and explore how they perform against an equivalent rival, the standard EDLCwith specific focus on the instantaneous initial charge performance of Lithium Ion Capacitors compared to the other. The focus of this study model is the behaviour of a standard EDLC Super-capacitors Equivalent Series Resistance, “ESR” versus an LIHC Super-capacitor “ESR” of comparable specification in the initial seconds of state of charge.
Loss of heterozygosity at the BRCA1 locus in Romanian cancer patients

BRCA1 is a tumor suppressor gene and any alteration of its functions can contribute to cancer development and progression. The loss of heterozigosity (LOH), meaning the loss of the normal functional allele in a heterozygous locus of a tumor suppressor such as BRCA1 gene, leads to wild-type gene inactivation and can be correlated with cancer. The role of BRCA1 LOH has already been demonstrated in familial and sporadic breast cancer. Little is known about BRCA1 LOH correlated with other types of familial cancers such as prostate cancer, esophageal cancer or gastric cancer and even less about BRCA1 LOH correlations with the types of sporadic cancers. The aim of this study was to investigate the correlation between distinct BRCA1 alterations and tumor site or cancer progression in Romanian patients with prostate, esophageal and gastric cancer. For this purpose polymerase chain reaction (PCR)-based microsatellite analysis was used to detect LOH occurring in regions mapping for BRCA1 gene. From all the five analyzed microsatellites, three (D17S855, D17S856 and D17S1322) presented loss of heterozygosity in the DNA extracted from the tumor tissue of different patients. 28% of all analyzed patients, presented loss of heterozygosity of at least one microsatellite marker corresponding to BRCA1 gene locus.
Evaluation of the Effects of Curcumin and Lycopene Treatment on Human Lymphocytes before 2 and 6 Gy of 6 MV X-Ray Irradiation

Introduction: Today, the use of ionizing radiation in medicine has grown as an important tool for diagnosis and treatment of diseases. However, the harmful effects of radiation should be also considered. Some substances such as lycopene and curcumin can reduce or increase the harmful effects of radiation on humans. So the aim of this study was to evaluate the radioprotective effects of lycopene and curcumin based on the MN assay. Material and Methods: In this study, the effects of lycopene and curcumin on reducing or increasing the harmful effects of radiation were studied using the micronucleus assay. The effects of lycopene (5 μg/mL) and curcumin (5 μg/mL) were evaluated at radiation doses of 2 and 6 Gy. Results: The results indicated that the simultaneous use of curcumin and lycopene can be radioprotective at low radiation doses (2 Gy; p 0.05). Conclusion: Based on the present results, further research using other methods may contribute to our understanding of the effect of simultaneous use of curcumin and lycopene at low and high doses of X-ray radiation.
Efficient Dense Spatial Pyramid Network for Lane Detection

Lane detection separating the roads and positioning each lane is a significant task in Autonomous-driving field. Most of existing methods take lane detection as a semantic segmentation problem, and the methods based on encoder-decoder networks achieve robust performances than traditional methods with the disadvantages of large amounts of parameters and high computational cost. To improve efficiency and better adapt to adverse environments, we propose an EDSPnet by compiling the efficient dense module of depthwise dilated separable convolution (EDD module) and dense spatial pyramid (DSP) module. The two proposed modules enable our network to make full use of the contextual information from different feature maps when compared to a chain of layers. Different from symmetrical segmentation networks, we concentrate on the encoder block and a simple decoder is designed to match the input resolution. The decoder is complemented by two methods of upsampling: bilinear interpolation and deconvolution, which guarantee the accuracy and efficiency simultaneously. Our method is evaluated on the TuSimple dataset, and the experimental results show that our network has less parameters and is still efficient even compared with the state-of-the-art semantic segmentation networks.

Analysis of Medical Supporting Facilities in Hainan's Senior Care Industry—Taking Boao Lecheng International Medical Tourism Pilot Zone as an Example

At the present, the problem of population aging in Hainan is becoming more and more serious, the number of "Snowbirds" is increasing, and the burden faced by the Hainan Senior Care Industry is adding. In order to effectively cope with the aging of the population and protect and improve people's livelihood, Hainan Province should accelerate the development of the Senior Care Industry, especially to improve the medical supporting facilities of senior care institutions to meet the urgent security needs of the elderly. This article is based on the study of the Boao Lecheng International Medical Tourism Pilot Zone, and makes a comprehensive analysis of Hainan’s elderly care institutions. It is found that Hainan’s Senior Care Industry has some problems, such as the contradiction between supply and demand, weak medical supporting facilities and unclear policies. To address these problems, the Hainan government should promote the opening of the Senior Care Industry, make up for the shortage of talents, and promote the full implementation of the policy.
REVIEW ARTICLE: Statics and dynamics of worm-like surfactant micelles

In certain surfactant solutions, such as aqueous cetyltrimethylammonium bromide (CTAB) in 0.1 M KBr, the amphiphiles are found to assemble reversibly into long, flexible worm-like micelles. Above a few per cent surfactant, these form an entangled viscoelastic fluid, reminiscent of a polymer solution. The authors review some recent experimental and theoretical progress concerning the equilibrium statistics and dynamics of these systems, which differ from normal polymer solutions in that the chains can break and reform reversibly.
Modification of starch and its application in leather making

In this paper, the general methods of starch modification are discussed. The applications of modified starch in leather making are summarized and the potential applications of the modified starch are considered. Though the studies of the modified starch were focussed on dialdehyde starch that has been used as tanning material in the past, the authors believe that graft starch may be a possible new material in leather making with uses as tanning agent, retanning agent, and finishing agent.
Pedestrian Recognition Based On Improved Semantic Segmentation Neural Network

At present, the existing Re-ID methods can’t align the target and the target in the image that should to be detected, which has been affecting the recognition accuracy. Although using semantic segmentation method can solve this problem, it brings new problems. The region which is considered as background by semantic segmentation neural network and discarded is likely to contain feature representations that are helpful for recognition. In this paper, an improved semantic segmentation method is proposed to re-divide the foreground and background regions. In order to avoid the influence of semantic segmentation errors on recognition accuracy, a new method is used to combine background and foreground regions. Experiments show that the accuracy of Re-ID is 84.52%, which is 3.33% higher than before.
Radical Inquiry—Liberatory Praxis for Research and Evaluation

Conventional social science research and evaluation too often replicate unjust and oppressive narratives and assumptions about young people of color's capacities, abilities, and needs, treating them primarily, and sometimes solely, as risk, problem, or disease. Overemphasis on “metrics of compliance,” such as personal behavior change, self‐efficacy, and resilience perpetuate this burden while ignoring those of survival, fortitude, and resistance in the context of structural/historical subjugation, discrimination, and state‐sanctioned violence communities of color have endured as part of US nation‐building. Invisible, insidious, and assumed, the dominant tropes and frameworks render white middle‐class subjectivities as the gold‐standard of achievement, status, and success. RYSE Youth Center in Richmond, California, creates safe spaces grounded in social justice that build youth power for young people to love, learn, educate, heal, and transform lives and communities. Toward this, RYSE employs Radical Inquiry through intentional, active, and ongoing listening. Radical Inquiry facilitates connection, proximity, and empathy—humanization.
Description of the nest and eggs of the Lesser Crescent-chested Puffbird (Malacoptila minor)

ABSTRACT The Lesser Crescent-chested Puffbird (Malacoptila minor) is one of the least known species of Bucconidae and the only form classified as endangered. Here we present the first description of the nest and eggs of this species from the Brazilian state of Maranhão. The nest consists of a ∼60 cm tunnel excavated in flat or slightly sloping ground leading to a broader nesting chamber. The floor of the chamber is covered with a thin layer of dead leaves and twigs on which 2–3 eggs are laid. The eggs are pure white, measure 20.30 (SD 0.22) mm by 24.23 (0.21) mm, and weigh 4.25 (0.96) g (n = 4). The nest entrance is surrounded by a ring of small straws and coarse petioles. Nests with a similar structure have been described in other Malacoptila species as well as Monasa and Nonnula.
