Arabic Creative and Participative Learning: In Search of a New Way of Language Learning by “El Jidal Reborn” Youth Community in Malang
Authors: Bin-Tahir Saidna Zulfiqar
Published: July 2020

The development of language skills and competencies of students experiencing various obstacles originates from the precise nature of learning. The need for developing language skills among students is inevitable, as is the need for Arabic, in the millennial era, in line with the integration of students into global communication and knowledge networks. Arabic has also become a source of knowledge in addition to other languages. The Language community in the millennial era cannot be seen as a meaningless community because its existence is an alternative way out in developing language skills that prioritize active, cooperative, and collaborative learning activities using participatory approaches. This paper shows that the development of community-based language skills has had implications for the success of language learning, as a counterpart to formal and standard language learning practices. As shown in this paper, the existence of a language community is a transformation of the learning process that is informal by providing facilities for students to carry out the process of learning, training, and mentoring that promotes active learning models, cooperative-collaborative, participatory in a language community. This paper suggests the need for a model for developing language skills through communities by formulating learning models based on collaborative achievement development, in response to individualistic language learning traditions.
Simulacro en las tensiones y disputas de lo femenino y masculino en Montaña adentro de Marta Brunet
Authors: García Francisco
Published: July 2020

Este artículo revisa las estrategias utilizadas por Marta Brunet en su novela Montaña adentro (1923) para lograr validarse dentro del canon literario de su época. Tensionar lo femenino y lo masculino, así como asumir una máscara en su escritura, le permiten sostener su proyecto y lograr una posición relevante en el campo cultural dominado por concepciones y presupuestos masculinos. Se propone la obra Montaña adentro como lugar en donde puede leerse el simulacro y la permanente tensión de los signos que, finalmente, configuran su proyecto de escritura.
subjetividade silenciosa
Authors: Bernardes Rogéria Guimarães Alves , Almeida Leonardo Pinto
Published: July 2020

O presente artigo propõe-se a estabelecer um diálogo com o monaquismo beneditino, buscando situar a singularização monástica nos contextos contemporâneos, pelo viés dos estudos da subjetividade. Utilizando o método bibliográfico, partimos de uma retrospectiva histórica, localizando as origens do monaquismo cristão na figura dos “padres do deserto”, dos séculos III e IV da nossa Era. Detendo-nos em Bento de Núrsia e no documento que lhe é atribuído – Regra de São Bento – localizamos os monges beneditinos expandindo as fronteiras da cristandade ocidental ao longo do medievo, influenciando séculos do ocidente europeu. Nessa trajetória, observamos a importância das práticas contemplativas e da oração comunitária – a Liturgia das Horas – na caracterização de tal movimento, o qual, na contemporaneidade, mantém-se fiel às suas  tradições culturais. Nesse sentido, buscamos refletir sobre a capacidade de resistência e de adaptação do monasticismo beneditino, diante das constantes transformações sociais e dos contextos capitalistas próprios da atualidade.
Processos mediadores na formação do leitor
Authors: Gibim Gabriela de Sousa , Gomes Cláudia Aparecida Valderramas
Published: July 2020

Este artigo apresenta o relato de uma pesquisa em psicologia que buscou identificar nas mediações presentes na história de um sujeito, da infância à adolescência, características do seu processo de formação como leitor. O estudo consistiu na entrevista de uma adolescente utilizando, como procedimentos metodológicos, a História Oral associada à interpretação por Núcleos de Significação, compondo, assim, um campo de análise entre a história da entrevistada em contraponto e complemento às produções científicas que discorrem sobre a leitura e sobre seus modos de subjetivação, segundo a teoria Histórico-Cultural. Os resultados evidenciaram que a categoria atividade foi capaz de explicar a mediação interposta entre a linguagem escrita, representativa do patrimônio humano-genérico, e sua consolidação na formação humana singular de um sujeito leitor. O estudo reitera a função da educação escolar, notadamente nos espaços da educação infantil e do ensino fundamental, na configuração desses processos mediadores.
Fundamentos estrutural-fenomenológicos da percepção a partir de Merleau-Ponty
Authors: Verissimo Danilo Saretta
Published: July 2020

Neste artigo, evidenciamos e discutimos fundamentos de uma concepção estrutural-fenomenológica da percepção a partir de Merleau-Ponty. Focalizamos extratos de investigações do filósofo acerca da organização perceptiva, mais especificamente, sobre a relação entre a propriedade objetivante da percepção e a sua articulação com o fundo perceptivo. Nossa argumentação centra-se em três pontos principais: a relação entre a propriedade presentativa da percepção e o campo da sua manifestação a partir de pressupostos fenomenológicos e gestaltistas; a atestação, mediante o exame da crítica à hipótese de constância, da operância silenciosa do fundo perceptivo; e a exploração dos fatores funcionais envolvidos na organização perceptiva.
Ausência de espiritualidade e sociose
Authors: Storck Igor , Holanda Adriano Furtado
Published: July 2020

Neste artigo, busca-se resgatar percepções centrais das obras do psiquiatra e psicólogo holandês Jan Hendrik Van den Berg; a forma como compreende o inconsciente, a releitura que faz acerca das neuroses, propondo sua substituição terminológica para socioses e ampliando o sentido contido no termo, permitindo reflexões valiosas e interlocuções profundas com a psicologia da religião. Se na época freudiana a inconscientização da sexualidade e da agressividade provocavam quadros sindrômicos bem específicos, a sociose enfrentada pelo sujeito hodierno é o esquecimento da espiritualidade. O psiquiatra advoga que a espiritualidade como dimensão humana, enquanto for negligenciada pela sociedade, continuará a produzir pessoas esvaziadas, medíocres, que não reconhecem seu lugar no mundo e tampouco conseguem desenvolver boas relações sociais. Endossa-se muito da percepção de Van Den Berg ao
apontar o atual momento histórico de resgate da espiritualidade já que, como dimensão humana, assim como a sexualidade, deveria ser reintegrada à existência.
Candomblé Ketu e o sincretismo religioso no Brasil
Authors: Gaia Ronan da Silva Parreira , Scorsolini-Comin Fabio
Published: July 2020

A figura de Òṣàlá ou Oxalá é muito presente na cultura religiosa brasileira, principalmente por conta do sincretismo religioso. A forma orgânica como se desenvolveram as religiões de matriz africana no Brasil estabeleceu hoje um quadro complexo, mas infelizmente folclorizado e muitas vezes reduzido a uma simplicidade, fruto de estigmas e de uma trajetória racista em essência. O Candomblé e a Umbanda estão presentes na vida do brasileiro, tal como seus cultos. Mesmo para aqueles não iniciados, Òṣàlá está no imaginário social justamente por essa popularidade. É no intuito de sintetizar essas muitas ideias que esse artigo se dedicou a organizar as percepções existentes sobre Òṣàlá e Oxalá, traçando-as sob as perspectivas do Candomblé de nação Ketu e da Umbanda. Perpassando por problemáticas históricas, ritos de culto, questões raciais e reflexões epistemológicas e etimológicas, apresenta-se um material reflexivo e crítico sobre a presença de Òṣàlá em solo brasileiro.

Authors: Goulart Maria Stella Brandão , Venturini Ernesto , Chaves Adelaide Lucimar Fonseca
Published: July 2020

Este artigo aborda o processo de desinstitucionalização no contexto da reforma psiquiátrica ocorrido em Ímola a partir da narrativa de brasileiros e brasileiras que participaram de seu cotidiano ao longo dos anos noventa. A pesquisa que sustenta o artigo procurou delinear as conexões entre Brasil e Itália no que concerne às contribuições no conjunto de ações que resultaram no fechamento dos manicômios e na constituição dos serviços territoriais (centros de saúde mental, centros diurnos) e de associações e cooperativas que sustentaram projetos de inclusão social. A metodologia utilizada nesta pesquisa qualitativa apoiou-se na realização de entrevistas semiestruturadas com integrantes dos serviços de Ímola de ambas

as nacionalidades. Assim, foram identificadas práticas relevantes que denotam uma participação efetiva de brasileiros e brasileiras, como educadores profissionais e assistentes de base, que não apenas impactaram o cotidiano assistencial como também colaboraram para a construção de cultura e relações inclusivas, inventivas, reflexivas e propositivas.

EXERGY-BASED CONTROL STRATEGY IN A DWELLING VENTILATION SYSTEM WITH HEAT RECOVERY
Authors: Voloshchuk Volodymyr , Polishchuk Mariya
Published: July 2020

The paper presents energy and exergy analysis of a typical dwelling ventilation system with heat recovery for Ukrainian climatic conditions using a quasi-steady state approach over 24-hour time-steps. Evaluation of such systems on the base of the first law of thermodynamics demonstrates that heat recovery is beneficial for the whole variety of operational modes. Such methodology identifies as a thermodynamic inefficiency only energy losses to the surroundings with the exhaust air. The exergy-based analysis can detect additional inefficiencies due to irreversibilities within the components of the system. As a result the exergetic investigations show that for the ventilation systems there are operating conditions for which heat recovery increases exergy of fuel expended to provide the ventilation air compared to cases without bringing any recovery of heat and additional power consumption to drive the air flow by the fans. For the specified system, in case of switching ventilation unit to the operation mode of lower values of spent fuel exergy it is possible to provide annual saving of the primary energy sources from 5 to 15%.

Published: July 2020

A Gestão do Conhecimento é uma área que propõe meios para uma organização capturar, estruturar e disseminar o conhecimento. Esse conhecimento pode ser desenvolvido no ambiente organizacional, partindo do indivíduo e sendo compartilhado em grupos. Para que o compartilhamento aconteça é necessária a criação de um ambiente propício para tal. Entretanto, esse mesmo ambiente não é suficiente para estimular tal compartilhamento uma vez que outras variáveis podem influenciar na interação dos indivíduos sendo, uma delas, as emoções positivas. Nesse sentido, o objetivo desta pesquisa é apresentar uma revisão sistemática da literatura que identifica os estudos publicados em periódicos nacionais e internacionais e que tratam do compartilhamento do conhecimento e das emoções positivas. A revisão sistemática foi executada seguindo seis etapas. Apesar dos resultados aqui alcançados apresentarem a tendência crescente no número de publicações sobre o tema investigado entre 2011 e 2020, ainda há poucos trabalhos acerca deste tema, merecendo a atenção dos pesquisadores devido à influência das emoções na forma em como as pessoas compartilham seus conhecimentos.

MENYAMAKAN POLA PIKIR ORANGTUA, GURU, DAN SISWA : SEBUAH USAHA MEMPERKENALKAN GAWAI SECARA BIJAK
Authors: Novitasari Nine Febrie
Published: July 2020

Penggunaan teknologi oleh anak bukanlah hal yang baru. Saat ini, hampir semua anak memiliki gawai sendiri seperti telepon pintar, tablet, atau laptop. Sayangnya, penggunaan gawai oleh anak seringkali tanpa melalui pengawasan yang cukup dari orangtua di rumah. Beberapa orangtua memberikan gawai kepada anak mereka dan memberikan akses untuk menggunakannya tanpa adanya kontrol terhadap apa saja yang dilakukan anak dengan gawai mereka. Sebagai pengganti orangtua di sekolah, guru juga memiliki peranan yang penting dalam membantu pengawasan penggunaan gadget oleh anak. Namun sayangnya, beberapa guru masih tidak sadar bahwa peranan mereka cukup signifikan dalam menanamkan pemahaman ini pada anak. Hal ini dibuktikan dengan masih banyaknya bentuk penyalahgunaan gawai oleh anak saat di sekolah. Padahal, jika digunakan secara tepat, gawai memiliki manfaat yang sangat banyak dalam mendukung proses belajar anak di sekolah. Terkait dengan hal ini, kami mencoba memberikan sosialisasi pada guru, wali murid, dan siswa di SDN 1 Seletreng tentang pentingnya kerjasama antara orangtua dan guru dalam memperkenalkan gawai secara bijak pada anak. Dengan adanya sosialisasi ini diharapkan anak memiliki pemahaman yang baik sejak dini tentang dampak positif dan dampak negatif dari penggunaan gawai. Tujuan jangka panjang dari kegiatan ini adalah adanya kerjasama yang baik antara orangtua dan sekolah (dalam hal ini guru) untuk bersama-sama mendidik dan menanamkan potensi yang baik bagi anak terutama dalam kaitannya dengan penggunaan gawai dalam mendukung pendidikan dan perkembangana anak baik secara kognitif, afektif, dan psikomotor. Hasil dari kegiatan ini adalah adanya respon positif berupa pemahaman orangtua dan guru tentang penggunaan gawai pada anak, dan adanya usaha-usaha nyata yang dilakukan untuk mengawasi penggunaan gawai oleh anak.
Subcranial surgery of nasal CSF leak, endoscopic capabilities
Authors: Palamar Orest , Huk Andriy , Okonskyi Dmytro , Aksyonov Ruslan , Teslenko Dmytro
Published: July 2020

Introduction: The problem of choosing surgical approach in the treatment of CSF leak is the subject of discussion depending of the location and the size of the bone defect of the skull base.
Materials and methods: 37 patients with nasal CSF leak were treated. In 17 cases, nasal CSF leak was caused by meningo(encephalo)cele. Spontaneous nasal cerebrospinal fluid occurred in 14 cases. In 3 cases, nasal CSF leak was the result of traumatic brain injury (in one case, the cause of nasal CSF leak was post-traumatic meningoencephalocele of the frontal sinus); in the other 3 cases there was postoperative wound nasal cerebrospinal fluid.
Results and discussion: Groups of patients were formed depending on the use of vascularized or moved (free) flaps: 1). Multilayer plastics of bone defects of the anterior and middle cranial fossae using displaced (free) flaps. 2). Multilayer plastic of bone defects of the anterior and middle cranial fossa using a nasoseptal flap or middle nasal concha on the leg. In all cases (100%) nasal CSF leak was eliminated. External lumbar drainage was performed in 6 patients and only in cases where the plastic of the bone defect was performed by displaced free flaps.
Conclusions: 1). The use of endoscopic endonasal techniques is a minimally invasive method to close skull base bone defects (including large – more than 20 mm) in the area of the anterior and middle cranial fossae. 2). Subcranial approaches are expedient, effective and technically more convenient for nasal CSF leak defects of the frontal sinus and defects in the anterior cells of the etmoid bone.3). Vascularized flaps is expedient for plastic at middle (11-20 mm) and big (more than 20 mm) bone defects of skull base.
Anticongestion therapy of sinusitis in children
Authors: Yurochko Fedir , Kopanska Dzvenislava
Published: July 2020

Sinusitis is one of the most common respiratory diseases in children. Swelling of the nasal mucosa and paranasal sinuses accompanies sinusitis; but this is not only a symptom, edema leads to blockage of the normal sinus drainage pathway, which is key in the pathogenesis of sinusitis.
Decongestants are considered a key treatment for sinusitis because they improve the function of the sinuses. According to EPOS-2012, treatment of acute sinusitis in children up to 5 days includes nasal lavage, decongestants, and in the absence of effect within 10 days, endonasal corticosteroids are added to the treatment.
Decongestants are prescribed from the onset of sinusitis in children. They not only alleviate the annoying manifestations of nasal congestion, but also keep unlocked paranasal sinuses, prevent the progression of sinusitis to bacterial and prevent complications.
In the treatment of sinusitis, we successfully combine the benefit of decongestants (rapid, relatively shortterm anti congestion) with the effect of endonasal corticosteroids (slow, relatively long-acting anti congestion). The article shows our algorithm of topical sinusitis treatment.

Determination of level and time thresholds for detectors with normalized indicator process
Authors: Егоров С.Б. , Горбачев Р.И.
Published: July 2020

«Выбросовая» вероятностная модель работы обнаружителя в режиме ожидания сигнала, предложенная авторами в [1], использована для оценки влияния селекции выбросов по длительности на вероятность ложной тревоги. Флюктуационные выбросы помехового индикаторного процесса, превысившие пороги селекции по уровню и длительности, трактуются как редкие события на интервале ожидания сигнала, подчиняющиеся вероятностному закону Пуассона. При условии, что средний период следования ложных выбросов превышает интервал корреляции индикаторного процесса, получено соотношение между средним числом выбросов любой длительности и средним числом выбросов, превысивших пороговую длительность. На основании известных числовых и вероятностных характеристик выбросов нормального стационарного случайного процесса получен уравнения, связывающие относительные пороги селекции по уровню и длительности с вероятностью ложной тревоги на интервале ожидания сигнала. Предложена методика определения порога селекции по длительности для снижения порога селекции по уровню до заданной величины.

«Emissional» probability model of the detector in stand-by mode proposed by the authors in [1], is intended for estimation of false alarm rate dependence from the value of time-selection threshold. Fluctuation emissions of the noise indicator process are interpreted as rare events correspond to Poisson distribution. Assuming that average rate of false alarms exceeds the correlation interval of indicator process, obtained equation between average number of false alarms of any duration and average number of false alarms exceed the time threshold. Based on known numerical and statistical characteristics of emissions of normal stationary random process obtained equations, relating time and level thresholds with false alarm probability on stand-by mode time interval. Also suggested a method of determining time threshold intended to reduce level threshold.

Published: July 2020

The aim of this in vitro study was to evaluate the characteristics of four commercial dental composites: two dual-curing luting resin cements and two indirect composites for crowns and bridges. The novelty of the study consists in the use of combined characterization methods for the investigated materials, namely: after maintaining the samples in the water/ artificial saliva, besides sorption, the surface degradation of the samples was observed after their immersion period; thereafter, the immersion medium was lyophilized and then the percentage of residual monomer found in the medium was determined by HPLC. After 44 days, small concentrations of monomers have been determined in the aqueous/saliva extracts. SEM images show that the samples from each class of material, with a higher content of inorganic filler, exhibit a larger erosion of the surfaces after contact with water compared to the other two samples that show a larger erosion of surfaces after contact with saliva than with water. The surface of the dual-curing resin cement with a higher content of inorganic filler is the smoothest from the samples exposed to saliva, instead the other resin cement is the roughest, as shown by AFM analysis. The overall observation reveals that the samples kept in saliva are rougher than the ones kept in water. Smooth surface materials of both classes of materials ( with a higher content of inorganic filler) have absorbed a higher amount of water / saliva compared to materials with a rougher surface.Water sorption in the composite resins is influenced by the hydrophilicity of the monomers, the nature and size of the inorganic filler particles, and the quality of the matrix / filler interface.

In this study, with the purpose of examine the impact of discrete polypropylene fiber on frost resistance of cemented soil, cemented soil treated with polypropylene fiber is used as the research sample. Firstly, the impact of curing time, fiber content and length on the strength of cemented soil has been considered. And then, the frost resistance characteristics of cemented soil reinforced by polypropylene fiber with the content of 0.5% have been investigated. The results show that with the development of curing time, the strength of cemented soil increases logarithmically. By adding an appropriate amount of polypropylene fiber, the strength of the specimen may be improved. In this study, cemented soil reinforced by polypropylene fiber 0.1% in content and 3 mm in length has the best reinforcement effect. After 21 cycles of freezing and thawing processes, a sharp decline in strength of cemented soil without fiber, and the strength loss ratio is up to 45%. There are cracks in the specimens, and some of the specimens have broken off. Differently, after 21 freeze-thaw cycles, the strength of the cemented soil with fiber decreased less, and the strength loss ratios are between 1 and 13%, and there are only small cracks on the surface of specimens. The results show that adding discrete polypropylene fiber is a suitable method to prevent the generation and development of internal cracks in the cemented soil during freezing and thawing, thereby improving the frost resistance. These results can be used as a reference for the application of cemented soil reinforced with fiber in seasonal frozen regions.

Determining the dynamic properties in the frequency domain of aircraft structural elements is a very important aspect taken into account nowadays by aircraft manufacturers. One of the helicopters most exposed element to structural vibrations is the rotor blade, thus making its construction and the material choice a very important decision. Finite element methods can be used to assess the vibrational properties of such elements, in order to prove their airworthiness. The main objective of the article is to study how the use of different materials affects the structural behavior of the helicopter tail rotor blade, with regard to the frequencies at which these structures are prone to vibrate. The blade profile is the NACA0012 symmetric airfoil used on the IAR330 helicopter tail rotor blade and the main objective is to identify the best inner core material, while highlighting the importance of polymeric materials.

The concept of ballistic protection is a subject of great importance and is defined as representing all the capabilities of the military vehicle to withstand attacks, in order to ensure protection of the crew during the missions. The projectile-plate impact research must answer a series of questions on designer or fighter behalf, among which the most important would be whether the bullet penetrates or perforates and whether the velocity after the perforation ensures a lethal effect on the personnel. The current paper presents the numerical evaluation of the working together of aluminum layers with plastic materials in a multilayer structure with honeycomb core, on impact with a rigid projectile. Plastic materials have revolutionized many industries and they are increasingly used due to their main properties, low mass and high strength. The research included the use of plastics, the positioning within the panel and the study of the two constructive versions of the structure, with coupled and uncoupled layers. Post-processing model and interpretation of the results are offered and these could be enriched and customized for other situations, similar or less similar, implicitly, the method is provided, finding a quick answer to certain questions.

This paper presents a monitoring of groundwater and surface water in the mining area Tg. Ocna, by analyzing 16 physico-chemical parameters (pH, turbidity, dissolved oxygen, Pb, Ni, Cu, Fe, Mn, Zn, Cr, Mg, SO42-, Al, NO2-, NO3-, NH4+), from three rivers Slanic, Trotus and Valcele, a small lake Groapa Burlacu, a fountain and three monitoring drilling wells (F11, F16 and F17). Studies on the quality of surface water and groundwater in areas near mines are important due to extraction and exploitation of salt. The samples were collected in April 2019. Following the analyzes, their results are included in the following concentration ranges: pH 7.21 to 8.46 unit. pH, turbidity 0.54 to 169 NTU, dissolved oxygen 6 to 8.59 mg/L, Pb 0.075 to 0.095 mg/L, Ni 0.026 to 1.05 mg/L, Cu 0.088 to 0.809 mg/L, NO2- 0.001 to 0.037 mg/L and NO3- 0.290 to 4.34 mg/L. The pH, turbidity and dissolved oxygen were measured in situ using portable equipment�s. As for the other parameters, they were analyzed in the water laboratory from Vasile Alecsandri University of Bacau by using spectrophotometry. Some concentrations of the physico-chemical indicators of the water samples analyzed were found to be more than the water quality classes.

Chemical pollution in rivers ecosystems is leading towards an increase in the concentrations of heavy metals in fish body, which might have a negative impact on humans. The fish were collected from a protected Natura 2000 area in the Moldavia region, eastern Romania named �Buhusi-Bacau-Beresti� Storage basin. The aim of this study was to measure the heavy metal concentrations in water, sediment and fish meat (muscles and gills), in order to assess the human health risk due to consumption. Industrial effluents discharged into the environment pose a serious threat for the agricultural products and living organisms. In view of this, level of some heavy metals, such as: Cd, Zn, Pb and Cu present in water, sediment and fish tissue samples of fish populations from the area studied were determined using wet digestion-based atomic adsorption method. This study revealed that the maximum Cd concentration (0.911 mg/Kg) was found in fish gills of specie European Perch � Perca fluviatilis and the minimum (0.0197 mg/Kg) was found in Zander - Sander lucioperca fish muscle sample. Zn levels in fish gills of the studied samples were ranged from 108.6698 mg/Kg to 195.4167 mg/Kg. Maximum Pb concentration in gills (1.924 mg/Kg) was found in fish sample of Zarte � Vimba Vimba, while the minimum concentration (0.45 mg/Kg) was found in European Perch � Perca fluviatilis. The heavy metal found in the samples analyzed in the largest quantity is Cu, in the gills of Northernpike - Esox Lucius fish.The concentration determined in samples exceeded the World Health Organisation maximum allowances. In order to assess the risk to which humans are exposed by eating infected meat with heavy metals, the target hazard quotient (THQ) values were estimated.

Heavy metal toxicity in plants is well known due to their severe phytotoxic effects and also because of their capability to accumulate in vegetables. The use of aromatic plants in remediation techniques has increased in the context of environmental pollution issues, including metal soil contamination. Cadmium is knowed as a toxic and bio accumulative element provided by natural or anthropic sources. In this context, the paper presents a laboratory experimental study aiming to evaluate the accumulating and transfer behavior of Cd in the plant organs of Sinapis alba L. (white mustard) and in the presence of essential elements (Ca, Mg, Fe, Zn, Mn, Cu, Ni). The study involves a comparison between white mustard cultivated in unpolluted soil and in two Cd polluted soils at values above the alert (2.8 mg/Kg), respectively intervention threshold for soils with sensitive use (5.6 mg/kg) according to the legislation in force in Romania. While Cd accumulated predominantly in roots (TC values 1.46 and 2.22), its transfer to the stem and leaves was observed too, the TF values for the aerial part of the plant being greater than 1. Moreover, the study showed that certain elements (Zn, Ca, Mg, Mn) were found in higher concentrations in plants subjected to Cd pollution than in the control sample indicating antagonistic effects and Cd toxicity limiting. Other essential metals, such as Cu, Fe and Ni were found in lower concentrations in intoxicated plants compared to control plants. Their translocation from soil in plant organs could be reduced by the Cd toxicity. Contrariwise, the mobility of these elements from roots to leaves could support the tolerance effect of plants to Cd stress. The study allows us to consider that Sinapis alba L. aromatic plants are suitable for soil phytoremediation technologies used in Cd decontamination.

The rotation regimes significantly alter soil properties, however, understanding the effect of crop rotation in various crops system was currently limited. The aim of this research was to reveal the variation in crop productivity, soil nutrients, enzyme activities, and bacterial community composition in vegetable-Polygonatum odoratum rotation horticulture. Thus, a 2-year field experiment was carried out under the P.odoratum-P.odoratum rotation (CC) and vegetable-P.odoratum rotation (FC) system through a randomized complete block design comprising of triplicate plots. The results showed that FC promoted most of the beneficial agronomic traits, soil nutrients, enzyme activities, and reducing root rot disease of P.odoratum. High-throughput sequencing revealed a shift in the microbial community groups with high environmental contaminants degradation ability, and a close correlation between increasing microbial diversity and major environmental factors like soil nutrients, enzyme activities under FC cropping system compared with CC. Therefore, crop rotations with vegetable- P.odoratum was recommended in cultivation.

On the relationship between competitive intelligence and innovation
Authors: Calof Jonathan , Sewdass Nisha
Published: July 2020

Innovation research suggests customer, competitor and market knowledge are important requirements for innovation. Researchers in competitive intelligence (CI) have proposed that there should be a relationship between CI and innovation. Yet despite both fields recognising the need for CI and related areas for innovation in their theories, there have not been many empirical studies that look at CI and innovation and those few studies that do exist have limited focus and have only looked at a small subset of CI variables (for example collection sources). The aim of this study is to examine if there is a relationship between CI and innovation. This was done by surveying Strategic and Competitive Intelligence Professional (SCIP) members and those attending SCIP events, and asking them about their intelligence practices and how innovative their company was. Ninety-five questions were asked about CI structure and organization, intelligence focus, information sources used, analytical techniques used, communication methods, and the management of the intelligence efforts. Of the 95 competitive intelligence measures used in this study, 56 (59%) were significantly correlated with the study’s measure of innovation. The measures within the CI organizational elements and CI management categories had the highest percentage of measures significantly correlated with innovation (90% and 89%). Four of the CI measures had statistically significant correlations above .300. These included the extent to which business decisions in the organization were better facilitated/supported as a result of intelligence efforts (.355), the number of performance measures used in assessing CI’s performance (.322) and decision depth (.313), which is a measure of the number of decisions that utilized CI. As a study of this nature measuring the relationship between CI and innovation has not been conducted previously, the findings can be beneficial to organisations using innovation to succeed in the competitive environment.
