Published: October 2022

This study aims to determine the effect of organizational culture on job satisfaction of employees of company which is engaged in retail. Participants in this study were employees who worked at company with a total population of 32 participants. The research method used in this study is a quantitative approach, with a non-probabilty sampling technique, namely saturated sampling by taking the entire population of 32 participants. Measurement of organizational culture uses a scale from Hartanto (2016) which develops a scale from Robbins (2011) to measure organizational culture with a cronbach alpha of 0.856. Meanwhile, to measure job satisfaction using a job satisfaction scale according to Spector (1997) with a cronbach alpha of 0.791. The scale is distributed in the form of a questionnaire, with data analysis using IBM SPSS Statistics version 26 and simple linear regression analysis with the equation Y= a + bX. The results of data analysis obtained the equation Y = 30,754 + 0.110 X. This means that the results of the study found that organizational culture had a significant effect on employee job satisfaction at company. Thus the research hypothesis which reads that there is a significant influence of organizational culture on employee job satisfaction at company accepted.

La discriminación por razón de sexo padecida por las empleadas del hogar familiar en la extinción de su contrato
Authors: Villalba Sánchez Alicia
Published: October 2022

El entorno donde se escenifica y la singularidad de la persona empleadora han dotado de especialidad la relación laboral del personal al servicio del hogar familiar. La salvaguardia del derecho fundamental a la intimidad personal y familiar y a la inviolabilidad del domicilio, por una parte, y la protección de una unidad económica que no destina los frutos del trabajo asalariado al mercado, por otra parte, han sido invocadas para sustentar un tratamiento jurídico desfavorable que se hace patente en la regulación de la extinción del contrato de trabajo de las personas empleadas del hogar. La fragilidad de la justificación aducida deja entrever el carácter discriminatorio de unas medidas que recaen sobre un colectivo mayoritariamente integrado por mujeres. Con el propósito de conjurar el trato discriminatorio en el que incurren ciertos aspectos de esta relación laboral de carácter especial, este trabajo ofrece una propuesta destinada a garantizar el equilibrio de los derechos fundamentales en juego, sin olvidar la viabilidad económica de una contratación propensa a permanecer sumergida.
Os livros de Projetos Integradores e de Vida do novo Ensino Médio brasileiro: uma análise sobre a abordagem do conceito de Amostragem e de Curva Normal
Authors: Araújo André Fellipe Queiroz , Guimarães Gilda Lisbôa
Published: October 2022

Neste artigo buscamos investigar a abordagem dos conceitos de Amostragem e de Curva Normal em livros didáticos de Projetos Integradores e de Projetos de Vida do novo Ensino Médio brasileiro. Trata-se de uma análise documental dos 14 livros de Projetos Integradores e 24 livros de Projeto de Vida aprovados pelo PNLD 2021. Os resultados apontam que esses livros apresentam interessantes propostas para o trabalho da Estatística e da Probabilidade, no Ensino Médio, com ênfase para a abordagem dos resultados de pesquisas estatísticas e realização das mesmas em contextos reais. Porém, também se evidenciou a predominância de situações que exploram a análise descritiva dos dados amostrais em detrimento das inferências informais e poucas situações que exploram o modelo da Curva Normal. Diante disso, acreditamos que os livros didáticos do Ensino Médio deveriam abordar com um maior aprofundamento a Estatística, contemplando aspectos da Amostragem relacionando com o modelo da Curva Normal, através de situações que envolvam, por exemplo, a incerteza, variabilidade amostral, propriedades da Amostragem, a distribuição de probabilidades, propiciando aos estudantes um leque maior de possibilidades para a análise de dados.

Em 13 de agosto de 2021 foi aprovado e homologado o Referencial Comum Curricular para o Ensino Médio do Paraná, sendo este o documento norteador para o processo de ensino e elaborado a partir da Lei 13.415, de 16 de fevereiro de 2017 e homologação da Base Nacional Comum Curricular (BNCC). Esse documento prescreve e indica compreensões sobre a matemática focado em competências e habilidades, porém, pouco exploradas. Nesse contexto, compreendemos importante ser investigada sob a seguinte interrogação: “como se mostra a matemática no Referencial Curricular do Novo Ensino Médio no Estado do Paraná? Para tanto, fomos aos sentidos da matemática que se manifestam nas competências específicas e habilidades do documento na área da Matemática e suas Tecnologias. De todo o movimento analítico realizado, nota-se que há uma forte indicação de descentralizar a matemática dela mesma, partindo daquilo que denominam de “realidade”. Ainda que a matemática seja um importante componente do currículo, podendo ser distinguido dos demais, ela é reposicionada e, portanto, condicionada a propósitos e valores específicos, como o seu papel na vida individual e coletiva.

Acinetobacter baumannii from the one health perspective in Nigeria: A systematic review of literature in the last decade (2011-2021)
Authors: Ajoseh Samuel O. , Akinyemi Kabiru O. , Abegunrin Rebecca O. , Neubauer Heinrich , Wareth Gamal
Published: October 2022

Multidrug drug-resistant (MDR)-Acinetobacter baumannii (A. baumannii) is one of the most feared nosocomial bacterial agents worldwide, and the World Health Organization classified carbapenem-resistant strains as a priority ”1” critical pathogen. In Nigeria, the paucity of information on this pathogen makes it difficult to estimate its potential impact on public health and veterinary medicine. This systemic review was done to prepare an impact assessment for One Health based on the occurrence of A. baumannii in different environments and the antimicrobial resistance. A detailed search of articles on A. baumannii in Nigeria was conducted using search strings in the following databases: PubMed, Scopus, Google search engine, and Google scholars. This study revealed that 14 out of the 36 states in Nigeria reported A. baumannii. Specifically, 19/24 articles described isolates from clinical settings, 4/24 from the environment, and 1/24 from animal sources. A. baumannii occurrence of 9.15% (503/5496) was recorded from 8.4% (418/4950), 16.06% (80/498), and 10.42% (5/48) of samples of clinical, environmental, and animal origin by culture, respectively. The most common antibiotics to which A. baumannii was resistant were chloramphenicol, ampicillin-sulbactam, amoxicillin, amoxicillin-clavulanate, cefuroxime, ceftazidime, ceftriaxone, gentamycin, and tetracycline. Seventeen resistance determinants were described for A. baumannii isolates originating mostly from clinical sources with blaOXA-51 and blaOXA-23 gene makers frequently reported. This study demonstrates the lack of data on A. baumannii from animals. Clinical MDR- A. baumannii isolates, particularly in Intensive Care Units (ICUs), are a severe public health concern in Nigeria. Thus, findings from this review will form a baseline for future surveillance research.
A new methodology for measuring traveling quasi-5-day oscillations during sudden stratospheric warming events based on satellite observations
Authors: Ma Zheng , Gong Yun , Zhang Shaodong , Xiao Qiao , Huang Chunming , Huang Kaiming
Published: October 2022

Abstract. Enhancements of stationary planetary waves (SPWs) and traveling planetary
waves (TPWs) are commonly observed in the middle atmosphere during sudden
stratospheric warming (SSW) events. Based on the least squares fitting method
(Wu et al., 1995), numerous studies have used satellite measurements to
investigate the characteristics of TPWs during SSWs, but they have ignored the effect
of the SPWs. However, a rapid and large change in the SPWs during SSWs may
lead to significant disturbances in the amplitude of derived TPWs. In this
study, we present a new methodology for obtaining the amplitudes and
wave numbers of traveling quasi-5-day oscillations (Q5DOs) in the middle
atmosphere during major SSWs. Our new fitting method is developed by
inhibiting the effect of a rapid and large change in SPWs during SSWs. We
demonstrate the effectiveness of the new method using both synthetic data
and satellite observations. The results of the simulations indicate that the
new method can suppress the aliasing from SPWs and capture the real
variations in TPWs during SSWs. Based on the geopotential height data
measured by the Aura satellite from 2004 to 2021, the variations in
traveling Q5DOs during eight midwinter major SSWs are reevaluated using the
new method. The differences in the fitted amplitudes between the
least squares fitting method and the new method are usually over 100 m during
the SSW onsets. Our analysis indicates that previously reported Q5DOs during
SSWs might be contaminated by SPWs, leading to both overestimation and
underestimation of the amplitudes of the traveling Q5DOs.
Potential underestimation of ambient brown carbon absorption based on the methanol extraction method and its impacts on source analysis
Authors: Xu Zhenqi , Feng Wei , Wang Yicheng , Ye Haoran , Wang Yuhang , Liao Hong , Xie Mingjie
Published: October 2022

Abstract. The methanol extraction method was widely applied to isolate organic carbon
(OC) from ambient aerosols, followed by measurements of brown carbon (BrC)
absorption. However, undissolved OC fractions will lead to underestimated
BrC absorption. In this work, water, methanol (MeOH), MeOH / dichloromethane
(MeOH / DCM, 1:1, v/v), MeOH / DCM (1:2, v/v), tetrahydrofuran (THF), and
N,N-dimethylformamide (DMF) were tested for extraction efficiencies of
ambient OC, and the light absorption of individual solvent extracts was
determined. Among the five solvents and solvent mixtures, DMF dissolved the
highest fractions of ambient OC (up to ∼95 %), followed by
MeOH and MeOH / DCM mixtures (<90 %), and the DMF extracts had
significantly (p<0.05) higher light absorption than other solvent
extracts. This is because the OC fractions evaporating at higher
temperatures (>280∘) are less soluble in MeOH
(∼80 %) than in DMF (∼90 %) and contain
stronger light-absorbing chromophores. Moreover, the light absorption of DMF
and MeOH extracts of collocated aerosol samples in Nanjing showed consistent
temporal variations in winter when biomass burning dominated BrC absorption, while the average light absorption of DMF extracts was more than 2 times
greater than the MeOH extracts in late spring and summer. The average light
absorption coefficient at 365 nm of DMF extracts was 30.7 % higher (p<0.01) than that of MeOH extracts. Source apportionment results
indicated that the MeOH solubility of BrC associated with biomass burning,
lubricating oil combustion, and coal combustion is similar to their DMF
solubility. The BrC linked with unburned fossil fuels and polymerization
processes of aerosol organics was less soluble in MeOH than in DMF, which
was likely the main reason for the large difference in time series between
MeOH and DMF extract absorption. These results highlight the importance of
testing different solvents to investigate the structures and light
absorption of BrC, particularly for the low-volatility fraction potentially
originating from non-combustion sources.

Abstract. The accurate classification of aerosol types injected into the stratosphere is important to properly characterize their chemical and radiative impacts within the Earth climate system. The updated stratospheric aerosol subtyping algorithm used in the Version 4.5 (V4.5) release of the Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) level 2 data products now delivers more comprehensive and accurate classifications than its predecessor. The original algorithm identified four aerosol subtypes for layers detected above the tropopause: volcanic ash, smoke, sulfate/other, and polar stratospheric aerosol (PSA). In the revised algorithm, sulfates are separately identified as a distinct, homogeneous subtype and the diffuse, weakly scattering layers previously assigned to the sulfate/other class are recategorized as a fifth “unclassified” subtype. By making two structural changes to the algorithm and revising two thresholds, the V4.5 algorithm improves the ability to discriminate between volcanic ash and smoke from pyrocumulonimbus injections, improves the fidelity of the sulfate subtype, and more accurately reflects the uncertainties inherent in the classification process. The 532 nm lidar ratio for volcanic ash was also revised to a value more consistent with the current state of knowledge. This paper briefly reviews the previous version of the algorithm (V4.1/V4.2), then fully details the rationale and impact of the V4.5 changes on subtype classification frequency for specific events where the dominant aerosol type is known based on literature. Classification accuracy is best for volcanic ash due to its characteristically high depolarization ratio. Smoke layers in the stratosphere are also classified with reasonable accuracy, though during the daytime a substantial fraction are misclassified as ash. It is also possible for mixtures of ash and sulfate to be misclassified as smoke. The V4.5 sulfate subtype accuracy is less than that for ash or smoke, with sulfates being misclassified as smoke about one-third of the time. However, because exceptionally tenuous layers are now assigned to the unclassified subtype and the revised algorithm levies more stringent criteria for identifying an aerosol as sulfate, it is more likely that layers labeled as this subtype are in fact sulfate.
Is it possible to estimate aerosol optical depth from historic colour paintings?
Authors: von Savigny Christian , Lange Anna , Hemkendreis Anne , Hoffmann Christoph G. , Rozanov Alexei
Published: October 2022

Abstract. The idea of estimating stratospheric aerosol optical thickness from the twilight colours in historic paintings – particularly under conditions of volcanically enhanced stratospheric aerosol loading – is very tantalizing because it would provide information on the stratospheric aerosol loading over a period of several centuries. This idea has in fact been applied in a few studies in order to provide quantitative estimates of the aerosol optical depth after some of the major volcanic eruptions that occurred during the past 500 years.
In this study we critically review this approach and come to the conclusion that the uncertainties in the estimated aerosol optical depths are so large that the values have to be considered questionable. We show that several auxiliary parameters – which are typically poorly known for historic eruptions – can have a similar effect on the red–green colour ratio as a change in optical depth typically associated with eruptions such as, for example, Tambora in 1815 or Krakatoa in 1883. Among the effects considered here, uncertainties in the aerosol particle size distribution have the largest impact on the colour ratios and hence the aerosol optical depth estimate. For solar zenith angles exceeding 80∘, uncertainties in the stratospheric ozone amount can also have a significant impact on the colour ratios. In addition, for solar zenith angles exceeding 90∘ the colour ratios exhibit a dramatic dependence on solar zenith angle, rendering the estimation of aerosol optical depth highly challenging.
A quantitative determination of the aerosol optical depth may be possible for individual paintings for which all relevant parameters are sufficiently well constrained in order to reduce the related errors.
Selective deuteration as a tool for resolving autoxidation mechanisms in α-pinene ozonolysis

Abstract. Highly oxygenated organic molecules (HOM) from α-pinene ozonolysis have been shown to be significant contributors to secondary organic aerosol (SOA), yet our mechanistic understanding of how the peroxy radical-driven autoxidation leads to their formation in this system is still limited. The involved isomerisation reactions such as H-atom abstractions followed by O2 additions can take place on sub-second time-scales in short-lived intermediates, making the process challenging to study. Similarly, while the end products and sometimes radical intermediates can be observed using mass spectrometry, their structures remain elusive. Therefore, we propose a method utilising selective deuterations for unveiling the mechanisms of autoxidation, where the HOM products can be used to infer which C-atoms have taken part in the isomerisation reactions. This relies on the fact that if a C−D bond is broken due to an abstraction by a peroxy group forming a −OOD hydroperoxide, the D-atom will become labile and able to be exchanged with a hydrogen atom in water vapour (H2O), effectively leading to loss of the D-atom from the molecule. In this study, we test the applicability of this method using three differently deuterated versions of α-pinene with the newly developed chemical ionisation Orbitrap (CI-Orbitrap) mass spectrometer to inspect the oxidation products. The high mass resolving power of the Orbitrap is critical, as it allows the unambiguous separation of molecules with a D-atom (mD=2.0141) from those with two H-atoms (mH2=2.0157). We found that the method worked well and we could deduce that two of the three tested compounds had lost D-atoms during oxidation, suggesting that those deuterated positions were actively involved in the autoxidation process. Surprisingly, the deuterations were not observed to decrease HOM molar yields, as would have been expected due to kinetic isotope effects. This may be an indication that the relevant H (or D) abstractions were fast enough that no competing pathways were of relevance despite slower abstraction rates of the D-atom. We show that selective deuteration can be a very useful method for studying autoxidation on a molecular level, and likely not limited to the system of α-pinene ozonolysis tested here.

Abstract. Although radar-based quantitative precipitation estimation (QPE) has been widely investigated from various perspectives, very few studies have been devoted into extreme rainfall QPE. In this study, the performance of KDP-based QPE during the record-breaking Zhengzhou rainfall event occurred on 20 July 2021 was assessed. Firstly, OTT disdrometer observations were used as input to T-matrix simulation and different assumptions were made to construct R(KDP) estimators. Then, KDP estimates from three algorithms were compared for obtaining best KDP estimates, and gauge observations were used to evaluate R(KDP) estimates. Our results in general agree with previous known-truth tests, and provide more practical insights from the perspective of QPE applications. For rainfall rates below 100 mm h-1, R(KDP) agrees rather well with gauge observations, and the selection of KDP estimation method or controlling factor has minimal impact on QPE performance provided that the used controlling factor is not too extreme. For higher rain rates, significant underestimation was found for R(KDP), and a smaller window length results in higher KDP thus less underestimation of rain rates. We show that the “best KDP estimate”-based QPE cannot reproduce the gauge measurement of 201.9 mm h-1 with commonly used assumptions for R(KDP), and potential responsible factors were discussed. We further show that the gauge with the 201.9 mm h-1 report was located at the vicinity of local rainfall hot spots during 16:00 ∼ 17:00 LST, while the 3-h rainfall accumulation center was located at the southwest of Zhengzhou city.
Modelling ignition probability for human- and lightning-caused wildfires in Victoria, Australia

Published: October 2022

Abstract. Wildfires pose a significant risk to people and property, which is expected to grow with urban expansion into fire-prone landscapes and climate change causing increases in fire extent, severity and frequency. Identifying spatial patterns associated with wildfire activity is important for assessing the potential impacts of wildfires on human life, property and other values. Here, we model the probability of fire ignitions in vegetation across Victoria, Australia, to determine the key drivers of human- and lightning-caused wildfire ignitions. In particular, we extend previous research to consider the role that fuel moisture has in predicting ignition probability while accounting for environmental and local conditions previously identified as important. We used Random Forests to test the effect of variables measuring infrastructure, topography, climate, fuel and soil moisture, fire history, and local weather conditions to investigate what factors drove ignition probability for human- and lightning-caused ignitions. Human-caused ignitions were predominantly influenced by measures of infrastructure and local weather. Lightning-sourced ignitions were driven by fuel moisture, average annual rainfall and local weather. Both human- and lightning-caused ignitions were influenced by dead fuel moisture with ignitions more likely to occur when dead fuel moisture dropped below 20 %. In future, these models of ignition probability may be used to produce spatial likelihood maps, which will improve our models of future wildfire risk and enable land managers to better allocate resources to areas of increased fire risk during the fire season.

FROM SLININ TO CARROLL AND BACK: APOPHATICISM AND NONSENSE AS PRELIMINARIES FOR LOGICAL ANALYSIS
Authors: Тульчинский Григорий Львович
Published: October 2022

В логике и логической семантике традиционно реализуется установка на анализ экстенсивных (референциальных) отношений между совокупностями сущностей, образующих предметную область рассуждения. Так, несовместимость, тождество, пересечение, включение (рода и вида) есть отношения между объемами понятий как отношения между соответствующими множествами. При этом принципиальным является предположение о непустоте предметной области. Такая установка сообразна общей установке европейского рационализма на позитивное знание, подпитываемой катафатичностью смысловой картины мира. Расширение логического анализа на модальные, интенсиональные и эпистемические контексты потребовало уточнить содержания подобных онтологических допущений, результатом чего стали разработка широкого спектра семантики «возможных миров», аппарата логики, свободной от экзистенциальных (онтологических) допущений. В данной работе рассматривается возможность «апофатического» расширения логического анализа на суждения с отрицательными предикатами, восходящего к логике Льюиса Кэрролла, что позволяет получить ряд нетривиальных обобщений.

Logic and logical semantics are traditionally oriented towards the analysis of extensive (referential) relations between sets of entities that form the subject area of reasoning. Thus, incompatibility, identity, intersection, inclusion (genus vs. species) are relations between the extensions of concepts, i.e. relations between the corresponding sets. In this case, the fundamental assumption is that the universe is not empty. Such an attitude is characteristic of the general attitude of European rationalism towards positive knowledge, fuelled by the cataphatic semantic picture of the world. The extension of logical analysis to modal, intensional, and epistemic contexts posed the task of clarifying the content of such ontological assumptions. Such a refinement was the development of a wide range of semantics of “possible worlds”, the apparatus of logic, free from existential (ontological) assumptions. In this paper, we consider the possibility of an “apophatic” extension of logical analysis to judgements with negative predicates, which goes back to the logic of Lewis Carroll, which makes it possible to obtain a number of non-trivial generalizations.
ACCELERATED WEATHERING OF RUBBER WOOD-REINFORCED RECYCLED POLYPROPYLENE COMPOSITE
Authors: Adebayo A. B.
Published: October 2022

The successful development of durable wood-plastic composite (WPC) cladding poses a challenge, hence investigating the effects of water immersion-freeze-thaw treatment on the physical properties, flexural strength (FS), and morphology of wood-recycled polypropylene composites. The behavior of wood plastic composite is difficult to predict due to the complexity of the structure of the material. Wood consists of cells (fibers) arranged in an intricate pattern, and the behavior of the material is a result of the behavior of the cells and the cell arrangement. In this study, different approaches were employed to analyze various degradation in the wood plastic composite. This study shows whether the flexural strength and thermal stabilization of the WPC will reduce or boost after introduction to water immersion-freezing-thaw cycling, as well as the degree of modifications in the ground characteristics (shade and roughness) of the composites after introduction to water immersion. This research is composed of new research on the weathering of wood-polymer composites (WPCs) and the findings of this research will be derived from rapid laboratory studies.

Published: October 2022

O combate às perdas em um sistema de abastecimento de água é um desafio constante que as empresas de saneamento brasileiras enfrentam com grande dificuldade. Estimativas atuais conferem que 39% de toda a água tratada no país é desperdiçada, seja em perdas reais, como vazamentos, ou em perdas aparentes, ocasionadas principalmente por erros de medição. Objetivou-se neste trabalho, a análise do erro no volume das perdas aparentes nos hidrômetros, com enfoque no seu tempo de uso, localizados no Conjunto Habitacional Tenente Coelho II e III em Juazeiro do Norte – CE. Como metodologia, foi empregada a substituição, em março de 2021, de 619 hidrômetros existentes nos conjuntos habitacionais, todos com mais de sete anos de uso, por hidrômetros novos de mesma classe hidrométrica. Para um quantitativo amostral de 21 moradias, foram instalados hidrômetros em série, de modo a identificar o erro relativo entre o medidor velho, considerando medidas de 2020, com o medidor instalado em 2021. Os resultados obtidos demonstraram que o volume medido com o parque de hidrômetros novos foi inferior à demanda medida pelo parque de hidrômetros antigos. Já no grupo amostral de layout em série, o ganho volumétrico total ficou abaixo dos percentuais elencados na literatura. Esses resultados indicaram que, a ação da substituição em massa de uma determinada localidade, por medidores de mesma classe hidrométrica, deve contemplar outros fatores além da idade do parque de hidrômetros, tais como: abastecimento das residências ser de forma indireta; levantamento do perfil de consumo da população em estudo e; cálculo amostral do Índice de Desempenho de Medição – IDM. Evitando-se assim, ações que não trarão reduções das perdas aparentes e desviando possíveis esforços da companhia em ações mais interessantes para o sistema.

Published: October 2022

A integração da gestão dos recursos hídricos com a gestão ambiental é uma das diretrizes previstas para implementação da Política Nacional dos Recursos Hídricos e previsto nos Objetivos de Desenvolvimento Sustentável (ODS6). Apesar da previsão na legislação, nem sempre existe nos órgãos colegiados dos Comitês de Bacias Hidrográficas (CBHs), a efetiva representação de membros de Unidade de Conservação (UCs) que compõem, total ou parcialmente, a área de bacias hidrográficas. Os CBHs e os Conselhos Gestores (CGs) das UCs são espaços coletivos que fomentam a gestão participativa, com representantes de diversos setores da sociedade. O objetivo deste trabalho é contribuir com o fortalecimento das políticas ambiental e de recursos hídricos por meio de aspectos da governança para a consolidação da gestão participativa nos comitês de bacias e conselhos gestores de UCs, no estado da Paraíba. Quanto aos aspectos metodológicos, tratase de uma pesquisa aplicada, descritiva, qualitativa, com análise de estudo de caso da participação mútua dos membros do Comitê das Bacias Hidrográficas do Litoral Norte (CBHLN) e dos Conselhos Gestores da Área de Proteção Ambiental (APA) e da Área de Relevante Interesse Ecológico Manguezais (AIRIE) da foz do rio Mamanguape, no período de 2015 a 2018. O levantamento de dados foi realizado por meio de pesquisa bibliográfica, obtenção de informações junto aos órgãos gestores de recursos hídricos e das UCs. A análise das áreas de ocupação e de sobreposição das UCs e do CBHLN, foi auxiliada por meio da construção de mapa temático. Percebe-se que a integração de representantes do Conselho Gestor das UCs e do CBHLN foi efetivo, com incremento do número de atores sociais envolvidos nas discussões sobre recursos hídricos. Entre as Dimensões de governança, as que favoreceram a integração dos membros destes conselhos, se destacaram as dimensões Legal/Institucional, Relações Intergovernamentais, Interação Estado/Sociedade e dos Instrumentos de Gestão. São apontadas diretrizes de governança que contribuem para o fortalecimento e ampliação da integração no âmbito da gestão ambiental e de recursos hídricos, com garantia de participação de representantes nos órgãos colegiados do CBHLN e das UCs.

In this modern technological era today, green materials are highly regarded as one of the most important elements when designing and conducting an environmentally sustainable construction project. The cement that is utilized in conventional concrete today is one of the culprits for the high levels of carbon dioxide generated, which is damaging to the environment. Many researchers have shown and suggested that cement substitution is a favorite technique for minimizing the generation of greenhouse gas (GHG) emissions as well as substituting unused raw materials with concrete. The concept of green concrete promotes sustainable development as it utilizes the least natural resources during production and mainly depends on recyclable waste materials as its main raw material. This paper displays the various designs of green concrete in developed countries by partially replacing cement with recyclable materials such as fly ash, demolished waste from construction sites, electronic waste, carpet fiber waste, palm oil fuel ash, and others. Green concrete endorses the innovative and sustainable use of waste aggregate and unconventional alternative materials to substitute cement within concrete. It is crucial to adopt the use of green concrete, especially in developed countries, as they have the capacity and financial strength to ensure adequate training, public awareness, further research and demonstration projects, as well as suitable standards to be applied to endorse the global application of green concrete in infrastructure projects.

Authors: Al-Jaber Karim Abdul Hussein
Published: October 2022

The long jump is one of the popular games among most people of the world because it evokes a spirit of love and fun. The skills of the long jump are closely related to other sports sciences, including biomechanics, which detects errors and provides accurate information that the naked eye may not be able to see because of the speed you have. Hence, it was necessary to be careful in the proper planning of the sports training process and the preparation of the training curricula for the event and its implementation in the correct manner. The player who possesses this trait as well as some physical measurements such as height, for example, is qualified to perform the achievement, so it requires the player to possess these qualities to be able to achieve the target number, hence the importance of the research in identifying the relationship between some physical and physical variables and pushing the force and the extent of its contribution by a long jump.

Managing the Performance Management Process: The Importance of Employees’ Performance in Determining the Organisation’s Viability and Efficiency
Authors: Simpson Grace , Simpson Reckonel
Published: October 2022

Many organisations for a number of years have been placing emphasis on performance management (PM) as they have noticed the profound impact of PM on organisations’ human resource capacity and its overall productivity and sustainability. Traditionally, PM was seen as a human resource function but has now become the lifeblood of organisations and subsequently, is a joint effort of all heads of departments/units as well as employees alike. PM is predominantly about managing people and business processes and if not effectively managed can impact negatively on employees’ overall performance by lowering staff satisfaction level, decreasing staff morale and as a consequence impede productivity. Models such as the Balanced Scorecard, the European Foundation of Quality Management (EFQM) or the Ability Motivation and Opportunity (AMO) are crucial in determining how smoothly the PM process flows. How employees are managed throughout the performance management cycle is of utmost importance in determining the viability of any organisation. This paper is intended to discuss the extent to which the PM process can increase productivity, staff morale and job satisfaction within the organisation.
