Influence of Pipeline Leakage on the Ground Settlement around the Tunnel during Shield Tunneling
Authors: Shi Xin , Cao Yi , Rong Chuanxin , An Gangjian , Wang Houliang , Cui Linzhao
Published: December 2022

Shield tunneling is widely used in urban subway tunnel construction. Old urban underground pipelines generally have small leakages that are difficult to find. The water leakage significantly reduces the stability of the stratum, posing a threat to the safety of tunnel shield construction. Therefore, this study established 2D and 3D calculation models for analyzing the law of the leakage diffusion in the ground under water pressure, and the influences of the pipeline leakage range and leakage length on the changes in ground settlement during shield tunneling. The 2D model calculation results show that seepage water mainly diffuses vertically under gravity. As the pipeline leakage gradually reaches a predetermined depth, the simulation results tend to be consistent with the test results. The 3D model is more accurate than the theoretical solution in predicting the ground settlement because it can consider the influences of repeated disturbances in twin tunnel shield construction. The maximum ground surface settlement increases with the extent of the leakage length and leakage range, and the range is the main factor determining the settlement. At the interior of the ground, the seepage water has a greater impact on areas with strong disturbances and large soil losses.

Today, using systems based on renewable resources is a suitable alternative to fossil fuels. However, due to problems such as the lack of access in all the times needed to supply cargo and high-investment cost, it has not been well-received. Therefore, in this research, the modeling of the photovoltaic system with battery storage has been done to supply the required load, and various scenarios have been evaluated in terms of economic parameters and reliability indicators of the studied system for a better understanding of the comparison indicators. It has been evaluated from two modes, one connected to the network and one disconnected from the network. One of the important results is the supply of 56% of the load by the photovoltaic cell in the presence of the grid, which, in this scenario, the electrical load is supplied by the photovoltaic cell and the grid is 164.155 kWh/yr and 128.504 kWh/yr, respectively.
Impacts of Traffic Infrastructure on Urban Bird Communities: A Review
Authors: Sander Martha Maria , Tietze Dieter Thomas
Published: December 2022

With increasing urbanization and related loss of biodiversity, it has become increasingly important to understand the determinants of biodiversity in cities, and to learn how we can maintain existing habitats and improve their quality for both wildlife and humans. Detrimental effects of urbanization on animals such as noise and light pollution, have frequently been reported, but comparatively little is known about the connection between different types of traffic infrastructure and their impacts on urban birds. Here, we provide an overview of the existing knowledge about bird responses to traffic-related stressors, and most importantly, we highlight that this aspect has not been satisfactorily investigated in urban environments. Therefore, we suggest suitable study systems and designs with which the effects of traffic infrastructure on bird communities in cities could be studied, and how biodiversity, in tandem with human wellbeing, in cities would benefit from improvements to the existing infrastructures. In doing so, we aim to strengthen the connection between human wellbeing and birds through research that will ultimately facilitate the development of sustainable cities.
State Estimation and Remaining Useful Life Prediction of PMSTM Based on a Combination of SIR and HSMM
Authors: Tian Guishuang , Wang Shaoping , Shi Jian , Qiao Yajing
Published: December 2022

The permanent magnet synchronous traction motor (PMSTM) is the core equipment of urban rail transit. If a PMSTM fails, it will cause serious economic losses and casualties. It is essential to estimate the current health state and predict remaining useful life (RUL) for PMSTMs. Directly obtaining the internal representation of a PMSTM is known to be difficult, and PMSTMs have long service lives. In order to address these drawbacks, a combination of SIR and HSMM based state estimation and RUL prediction method is introduced with the multi-parameter fusion health index (MFHI) as the performance indicator. The proposed method’s advantages over the conventional HSMM method were verified through simulation research and examples. The results show that the proposed state estimation method has small error distribution results, and the RUL prediction method can obtain accurate results. The findings of this study demonstrate that the proposed method may serve as a new and effective technique to estimate a PMSTM’s health state and RUL.

Authors: Bermúdez-Hernández Jonathan , Cardona-Acevedo Sebastián , Valencia-Arias Alejandro , Palacios-Moya Lucía , Dioses Lescano Nelly
Published: December 2022

Recent mobility and transportation dynamics have shaped the main sustainability problems of today, evidencing the need to potentiate alternative, flexible, environmentally friendly transportation means—such as bicycles—that significantly contribute to the health and well-being of users. However, in cities that are just beginning to implement bicycle systems or are seeking to achieve high levels of bicycle use, it is important to know which are the most relevant factors that users consider when using this type of medium. Therefore, the objective of this study was to identify the main behavioural factors among users of the public bicycle programme EnCicla in the city of Medellín, Colombia. Confirmatory factor analysis of responses to a self-administered questionnaire, elaborated based on the Theory of Planned Behaviour, was conducted using the statistical tool Statistical Product and Service Solutions (SPSS). Among the main results, the behavioural factors that further explained behavioural intention were attitude towards behaviour and perceived behavioural control, with values of 0.579 and 0.519, respectively (Cramér coefficient or Cramér’s V). The relevance of these factors lies in the implementation of dynamics that affect a better assessment by users of public bicycles in the EnCicla system, increasing satisfaction with the service and promoting greater adoption in the context of current mobility needs. The practical implications of this study are related to the possibility of designing strategies and public policies to enhance this means of transport in the cities where it is implemented, or to prepare a possible implementation in those that plan to do so.
Modelling and Forecast of Future Growth for Shandong’s Small Industrial Towns: A Scenario-Based Interactive Approach
Authors: Yang Yang , Liu Chunlu , Li Baizhen , Zhao Jilong
Published: December 2022

The industrial small-town development process in Shandong is influenced by the urban agglomeration strategy and the regional collaborative production, thereby resulting in a challenge of growth boundary planning. How to build a growth forecast decision support system to help small industrial towns maintain sustainable development with limited trial and error costs is an essential topic in the current research of small town-related fields. Empirical analysis reveals that the growth factors of small towns differ from the factors of cities due to the other-organization planning management system and self-organization construction activities that coexist in small towns. Besides, due to the size of small towns, the impact of policy changes in small towns is more significant than in cities. Furthermore, as part of the regional production chain, small industrial towns are most vulnerable to uncertain external disturbances. Therefore, it is necessary to formulate different development scenarios according to possible disturbances and output corresponding development forecasts. The research aims to build a decision-making support system for Shandong’s small-town planning based on an urban modeling approach using geographic information technology and scenario planning. Considering the mutually driving effects of the objective environment and subjective policies of Shandong’s industrial towns, as well as the corresponding dynamic mechanisms and comparing the theoretical basis and limitations of the different modeling approaches, this essay constructs a model system based on a mathematical model and a system dynamics model. It is also an interactive model accompanied by applicable rules and factors so that initial information and relevant development goals can be inputted into the model system to simulate the influence of different policies and identify the small industrial town growth scenarios.

Published: December 2022

In an effort to reduce environmental pollution and energy consumption, the Chinese government strongly promotes the usage of electric vehicles. However, studies focusing on assessing consumers’ willingness to pay (WTP) for electric vehicles (EVs) are limited in the country. This research aims to address this research gap by examining influencing factors of consumers’ WTP for EVs in the Chinese perspective. Combined with the existing consumers’ intention factors, the current study further contributed by augmenting the theoretical framework of the Theory of Planned Behavior by including three new dimensions (performance expectancy, information loaded, and perceived risk) to comprehensively analyze the willingness of Chinese consumers. Analysis is performed on survey data from 498 consumers using EVs in Beijing, China. To evaluate formulated hypotheses, structural equation modeling approach is employed. Empirical findings reveal that environmental knowledge and performance expectancy positively and significantly influence behavioral intention. In contrast, overloaded information has a negative impact on behavioral intention. Moreover, subjective norms are significantly and positively related to behavioral intention. The research outcomes further disclose that perceived risk is positively and significantly related to behavioral intention. Finally, behavioral intention has a significant and positive association with WTP for EVs. The study contributes to the literature on sustainable consumption behavior and provides academics and practitioners with essential future directions.

Authors: Huang Gan , Yang Chao , Lei Jichong , Su Lingling , Chen Zhenping , Yu Tao
Published: December 2022

The choice of an appropriate fuel can effectively prolong the refueling cycle of a reactor core. The Th-U cycle and U-Pu cycle are commonly used fuel breeding cycles. Oxide fuels, nitride fuels, and metal fuels are the primary candidate fuels for lead-based reactors. For fuel selection, a core model of a 60 MWt reactor was established. The results show that the breeding performance of the breeding fuel Th-232 is better than that of U-238, and the driving performance of the driving fuel Pu-239 is better than that of U-235. Therefore, PuO2-ThO2, PuN-ThN, and Pu-Th-Zr fuels may have good performance. By comparing the reactivity loss of three types of fuel, it was found that the reactivity loss of PuN-ThN fuel is the smallest. Hence, using PuN-ThN fuel as a core fuel can result in a longer refueling cycle. On this basis, PuN-ThN fuel was used in the preliminary design of the 120 MWt core physical model. It can be seen that when PuN-ThN fuel is used as the core fuel, a smaller reactivity swing (1408 pcm), smaller power peak factor, and super long refueling cycle (more than 30 years) can be obtained.

Uncertainty Principles for the Two-Sided Quaternion Windowed Quadratic-Phase Fourier Transform
Authors: Bhat Mohammad Younus , Dar Aamir Hamid , Nurhidayat Irfan , Pinelas Sandra
Published: December 2022

A recent addition to the class of integral transforms is the quaternion quadratic-phase Fourier transform (Q-QPFT), which generalizes various signal and image processing tools. However, this transform is insufficient for addressing the quadratic-phase spectrum of non-stationary signals in the quaternion domain. To address this problem, we, in this paper, study the (two sided) quaternion windowed quadratic-phase Fourier transform (QWQPFT) and investigate the uncertainty principles associated with the QWQPFT. We first propose the definition of QWQPFT and establish its relation with quaternion Fourier transform (QFT); then, we investigate several properties of QWQPFT which includes inversion and the Plancherel theorem. Moreover, we study different kinds of uncertainty principles for QWQPFT such as Hardy’s uncertainty principle, Beurling’s uncertainty principle, Donoho–Stark’s uncertainty principle, the logarithmic uncertainty principle, the local uncertainty principle, and Pitt’s inequality.
Quantum Speed-Up Induced by the Quantum Phase Transition in a Nonlinear Dicke Model with Two Impurity Qubits
Authors: Lu Wangjun , Zhai Cuilu , Liu Yan , Song Yaju , Yuan Jibing , Li Songsong , Tang Shiqing
Published: December 2022

In this paper, we investigate the effect of the Dicke quantum phase transition on the speed of evolution of the system dynamics. At the phase transition point, the symmetry associated with the system parity operator begins to break down. By comparing the magnitudes of the two types of quantum speed limit times, we find that the quantum speed limit time of the system is described by one of the quantum speed limit times, whether in the normal or superradiant phase. We find that, in the normal phase, the strength of the coupling between the optical field and the atoms has little effect on the dynamical evolution speed of the system. However, in the superradiant phase, a stronger atom–photon coupling strength can accelerate the system dynamics’ evolution. Finally, we investigate the effect of the entanglement of the initial state of the system on the speed of evolution of the system dynamics. We find that in the normal phase, the entanglement of the initial state of the system has almost no effect on the system dynamics’ evolution speed. However, in the superradiant phase, larger entanglement of the system can accelerate the evolution of the system dynamics. Furthermore, we verify the above conclusions by the actual evolution of the system.
A Domain-Adversarial Multi-Graph Convolutional Network for Unsupervised Domain Adaptation Rolling Bearing Fault Diagnosis
Authors: Li Xinran , Jin Wuyin , Xu Xiangyang , Yang Hao
Published: December 2022

The transfer learning method, based on unsupervised domain adaptation (UDA), has been broadly utilized in research on fault diagnosis under variable working conditions with certain results. However, traditional UDA methods pay more attention to extracting information for the class labels and domain labels of data, ignoring the influence of data structure information on the extracted features. Therefore, we propose a domain-adversarial multi-graph convolutional network (DAMGCN) for UDA. A multi-graph convolutional network (MGCN), integrating three graph convolutional layers (multi-receptive field graph convolutional (MRFConv) layer, local extreme value convolutional (LEConv) layer, and graph attention convolutional (GATConv) layer) was used to mine data structure information. The domain discriminators and classifiers were utilized to model domain labels and class labels, respectively, and align the data structure differences through the correlation alignment (CORAL) index. The classification and feature extraction ability of the DAMGCN was significantly enhanced compared with other UDA algorithms by two example validation results, which can effectively achieve rolling bearing cross-domain fault diagnosis.
Cucumber Mosaic Virus-Induced Systemic Necrosis in Arabidopsis thaliana: Determinants and Role in Plant Defense
Authors: Pagán Israel , García-Arenal Fernando
Published: December 2022

Effector-triggered immunity (ETI) is one of the most studied mechanisms of plant resistance to viruses. During ETI, viral proteins are recognized by specific plant R proteins, which most often trigger a hypersensitive response (HR) involving programmed cell death (PCD) and a restriction of infection in the initially infected sites. However, in some plant–virus interactions, ETI leads to a response in which PCD and virus multiplication are not restricted to the entry sites and spread throughout the plant, leading to systemic necrosis. The host and virus genetic determinants, and the consequences of this response in plant–virus coevolution, are still poorly understood. Here, we identified an allelic version of RCY1—an R protein—as the host genetic determinant of broad-spectrum systemic necrosis induced by cucumber mosaic virus (CMV) infection in the Arabidopsis thaliana Co-1 ecotype. Systemic necrosis reduced virus fitness by shortening the infectious period and limiting virus multiplication; thus, this phenotype could be adaptive for the plant population as a defense against CMV. However, the low frequency (less than 1%) of this phenotype in A. thaliana wild populations argues against this hypothesis. These results expand current knowledge on the resistance mechanisms to virus infections associated with ETI in plants.
The Structural Identifiability of a Humidity-Driven Epidemiological Model of Influenza Transmission
Authors: Zhang Chunyang , Zhang Xiao , Bai Yuan , Lau Eric H. Y. , Pei Sen
Published: December 2022

Influenza epidemics cause considerable morbidity and mortality every year worldwide. Climate-driven epidemiological models are mainstream tools to understand seasonal transmission dynamics and predict future trends of influenza activity, especially in temperate regions. Testing the structural identifiability of these models is a fundamental prerequisite for the model to be applied in practice, by assessing whether the unknown model parameters can be uniquely determined from epidemic data. In this study, we applied a scaling method to analyse the structural identifiability of four types of commonly used humidity-driven epidemiological models. Specifically, we investigated whether the key epidemiological parameters (i.e., infectious period, the average duration of immunity, the average latency period, and the maximum and minimum daily basic reproductive number) can be uniquely determined simultaneously when prevalence data is observable. We found that each model is identifiable when the prevalence of infection is observable. The structural identifiability of these models will lay the foundation for testing practical identifiability in the future using synthetic prevalence data when considering observation noise. In practice, epidemiological models should be examined with caution before using them to estimate model parameters from epidemic data.
The Structural Characteristics of the Virtual Water Trade Network of the China’s Major Crops
Authors: Liang Xuan , Long Aihua , Yu Jiawen
Published: December 2022

The original intention of virtual water trade (VWT) is to help water-scarce areas adjust the crop trade structure to alleviate the water shortage problem. However, China’s existing virtual water trade (VWT) must effectively alleviate the problem. This paper’s structural features and stability of the VWT network (VWTN) in China’s major crop trade between 2000 and 2017 were characterized using complex network theory. The results in terms of time scale showed that the total content of VW in China’s major crops increased by ~23.6% for 18 years. Trade relations among most regions remained stable, whereas a few areas changed: Jilin, Henan, and Heilongjiang played essential roles in the output network, and so did Guangdong, Shanghai, and Fujian in the input network. Attributed to policy adjustment, Henan and Jilin became more prominent in the output network with the gradual decline of Jiangsu’s position. Regarding spatial scale, the cumulative distribution of degrees consistent with the power–law relationship showed high variability and vulnerability of China’s VWTN, especially when nodes were weighted. Since areas with more VWT partners/content provided connectivity to those with fewer partners/content, it is worthwhile to focus on developing protection policies for critical areas. The virtual water trade from North China (water-poor) to South China (water-rich) is contrary to the distribution of water resources. A similar situation showed in a global world that the long-term supply relationship would aggravate the water resources shortage and food security. Furthermore, we suggest combining network theory and VWT to lay the foundation for the invulnerability research of VWTN and the optimal regulation of crops.

Dimethachlor is an herbicide used for oilseed rape protection. Previous studies have demonstrated its high mobility in the soil, which could lead to water contamination. This research aimed to determine the occurrence of dimethachlor and its metabolites (dimethachlor ethanesulfonic acid ESA and dimethachlor oxalamic acid OA) in surface water using a recently developed analytical method. This article is one of the first to document dimethachlor and its metabolites’ presence in surface water samples. The samples were collected from the Danube river and Tisza river. The quantitative determination of dimethachlor and its metabolites in the obtained extracts was done by high-performance liquid chromatography. Descriptive statistical methods, including correlation analysis, cluster analysis, and principal component analyses, were utilized to analyze method validation experimental results. In addition, the artificial neural network (ANN) model was applied as an optimization tool. The developed ANN model adequately predicted observed variables, suggesting the optimum results were obtained at a pH value 7, spike value 1, and injection volume equal to 0.5 μL. The average concentrations in Danube River samples were 1.51 µg/L for OA 0.01 µg/L for ESA, and 0.63 µg/L for DMC, while the average concentrations of chloroacetanilide herbicides detected in Tisza River samples were 1.43 µg/L for OA, 0.08 µg/L for ESA and 1.82 µg/L for DMC.

Published: December 2022

The efficiency and useful life of reservoirs are directly related to the production and input rates of sediments resulting from erosive processes at the edges and those resulting from the action of surface runoff in contribution areas and transported via tributary channels. Knowledge of the intensity, as well as the relationship between generation and input, allows more precise identification of critical environments, helping in the decision-making process and allowing the definition of mitigating measures. This work aims to relate the spatial variability of soil loss with the respective sediment transfer potential in two sub-basins tributary to the HPP Batalha reservoir in the Midwest region of Brazil. The methodology comprised the bivariate analysis between estimates of soil loss in areas of contribution and the Declivity-Extent Relationship along the channels. The results point to the configuration of four spatial patterns, indicating different levels of criticality in terms of sediment generation potential and transport capacity. In addition, they highlight basins with high potential and greater proximity to the reservoir, which constitute priority areas for monitoring, especially the conditions of soil cover and management, to contribute to the reduction of sediment inputs and prolong the efficiency of these structures.
Effects of Dry and Wet Negev Soil–Dust Deposition on the Induction of Autoxidation of Soil–Dust Lipid Components
Authors: Rontani Jean-François , Charriere Bruno , Menniti Christophe , Katra Itzhak , Aubert Dominique
Published: December 2022

Lipids and their oxidation products were quantified in loess samples from the Negev Desert (Israel), well known to be a source of desert dusts in the eastern Mediterranean Basin. The results obtained showed the presence of higher plant material (angiosperms and gymnosperms), but also bacteria and fungi. Although a strong autoxidation of lipids could be demonstrated, the resulting oxidation products appeared to be weakly accumulated, likely due to the high temperatures and solar irradiance observed in the Negev Desert. Incubation of this dust analogue in fresh water (to mimic their behavior in rainwater) resulted in the release of metal ions (mainly iron), but also a fast heterolytic degradation of their weak content of hydroperoxides. Induction of autoxidation processes in dry and wet atmospheric dusts arising from the Negev Desert in seawater (needing simultaneous presence of metal ions and hydroperoxides) seems thus very unlikely due to the relatively high pH of seawater hindering metal dissolution and the degradation of hydroperoxides in rainwater.
Optimization of Aeration Rate—Low Cost but High Efficiency Operation of Aniline-Degrading Bioaugmentation Reactor
Authors: Song Jianyang , Wang Chunyan , Peng Haojin , Zhang Qian , Li Yao , Wei Hua , Wang Hongyu
Published: December 2022

In this work, two sequencing batch reactors (R0 and R1) were built for treating 600 mg·L−1 aniline-containing wastewater. R1 was a bioaugmentation system with the addition of highly efficient aniline-degrading strain AD4 (Delftia sp.), while R0 served as a control system. The effects of aeration rates on R1 and R0 were investigated in the range of 300 to 800 mL·min−1. Results showed that the increase in aeration rates promoted the degradation of aniline in both R1 and R0. Under bioenhancement, the highest removal efficiency of aniline was stabilized above 99.7% in R1 while it was lower than 95.6% in R0. As for nitrogen removal, increasing aeration rates reduced the NH4+-N released from aniline degradation but caused the accumulation of NO3−-N and NO2−-N. R1 had a better total inorganic nitrogen removal efficiency than R0. The alpha biodiversity of both R1 and R0 reached the highest at 400 mL·min−1 and decreased at higher aeration rates. However, R1 always kept higher biodiversity than R0. Furthermore, the abundance of various functional bacteria was also higher in R1. This study revealed the high efficiency of bioenhanced activated sludge for the treatment of refractory wastewater and illustrated the importance of aeration control from the angle of energy saving, which demonstrated the potential of biofortification to help energy conservation and emission reduction.

Published: December 2022

This study aimed to investigate the effects of thermal stratification and complete mixing conditions on the bacterial diversity of a deep alkaline lake. For this purpose, the water and sediment samples were collected during the winter turnover and stratification periods, and bacterial communities were assessed by metabarcoding. The results showed that temperature shaped the bacterial community patterns in the lake. While the bacterial communities of the water samples showed high similarity during the mixing period, communities had distinctive patterns in the epilimnion and hypolimnion during stratification. The diversity and evenness of the bacterial communities increased with depth, whereas the bacterial communities of sediments were more even and diverse than in water. Proteobacteria members dominated the sediment communities representing 41% to 62% of the total reads in the samples. Particularly, Gammaproteobacteria was the major class found in the sediment; higher abundances were recorded in the mixing period representing 33–51%. Additionally, Actinobacteria species were more abundant in the water samples representing 22–52% of all reads during the stratification period. Due to the complete mixing conditions in the lake, a homogenized bacterial community structure was observed in the lake with minor spatial changes, and a clear divergence was observed between epilimnion and hypolimnion. On the other hand, the sediment bacterial community showed a more stable profile.
Impacts of Climate Change Induced Sea Level Rise, Flow Increase and Vegetation Encroachment on Flood Hazard in the Biobío River, Chile
Authors: Schoener Gerhard , Muñoz Enrique , Arumí José Luis , Stone Mark C.
Published: December 2022

River flooding is one of the most widespread natural disasters. Projections indicate that climate change will increase flood hazard in many areas around the world. In this study, we investigate the individual and combined effects of sea level rise, flow increase and riparian vegetation encroachment on flood hazard in the lower Biobío River, Chile. Results show that each has the potential to individually increase flood hazard in certain areas, and that individual effects can compound. Encroachment of riparian vegetation onto previously sparsely vegetated areas of the floodplain, likely a result of the Chilean megadrought, causes higher flow resistance and increased flooding during large events. Somewhat counterintuitively, drought has therefore led to an increase in flood hazard in the study area. Drought risk for most land areas across the globe is expected to increase with climate change. Potential future vegetation encroachment should therefore be included as a key variable in riverine flood hazard studies.
Investigations into the Usage of the Mineral Alginite Fermented with Lactobacillus Paracasei for Cosmetic Purposes
Authors: Tóth Pál , Németh Áron
Published: December 2022

A remarkable interplay between the skin and the fermentation of lactic acid bacteria (LAB) occurs. The lactate and amino acids in the supernatant of this bacteria help to hydrate the skin. The fermentation broth of lactic acid bacteria, generally referred as "lactic acid bacteria ferment" according to International Nomenclature of Cosmetic Ingredients (INCI), has been used to make a variety of cosmetic components. The goal of this study was to evaluate new approaches to assess ferment filtrates (also known as cell-free fermentation broths) that could be used in cosmeceuticals. Despite years of research on the production of lactic acid, aesthetic evaluations have not yet been performed. First, the Lactobacillus paracasei strain NCAIM B.01525 was employed in our research. Furthermore, a fermentation broth was produced containing the Hungaricum mineral alginite and the impact of hydration on human skin tested. The influence of alginite on the fermentation of LAB was also examined. According to the results of the trials, although alginite might double and triple biomass and specific growth rates, respectively, it cannot facilitate hydration of the skin. These results might contribute to the development of more widely accessible, environmentally-friendly cosmetic components in the future.
The Challenges of Transition to Practice Expressed Through the Lived Experience of New-to-Practice Nurses
Authors: Toothaker Rebecca , Rommelfaenger Marijo , Flexner Randi Sue , Hromadik Lora
Published: December 2022

Background: The nurse’s transition into practice is challenging. The need to facilitate a safe transition into practice and retain nurses is crucial in today’s healthcare.

Objective and Design: The qualitative study aim was to describe the lived experiences of new nurses’ safe transition into practice and their perceptions of functioning as safe practitioners.

Method: This descriptive, phenomenological arm of a larger, mixed methods study (Safety Transition Education to Practice study) interviewed 11 nurses with varied clinical backgrounds regarding their first six months as licensed nurses. Semistructured, one-to-one interviews with nurses representing geographical locations across the nation were conducted. Colaizzi’s method of analysis was used to extract themes.

Results: The data revealed five themes with subthemes. The most universal theme was lack of practical knowledge (skills dexterity, real-world knowledge), followed by impostor syndrome, safety culture (unsafe environment, lack of supplies, lack of mentoring/management), internalized fear, and seeking the sage.

Conclusion: The experiences support the understanding that transition to practice is overwhelming and uncertain. Academic faculty and practice nurses’ cooperative efforts can aid novice nurses in safe transition to practice through academic curriculum enhancement, preceptors, and nurse residency programs working toward narrowing the academic practice gap.

Au moment de l’accès à l’indépendance, le statut et la situation de la femme marocaine restent toujours marqués par de profondes inégalités comparés à ceux des hommes. Une lente évolution verra le jour à travers les effets de l’urbanisation, de l’entrée dans le monde du travail et de la maîtrise de la maternité. A partir des années 80, sous l’influence d’organisations féminines, la place des femmes dans la vie politique et sociale sera posée avec plus de force. Le débat se cristallisera avec vigueur autour des projets de réforme du code de la famille à partir des années 2000.

Sociétés militaires privées : la guerre par procuration ?
Authors: Cicchini Joëlle , Herrera Rémy
Published: December 2022

Une question d’importance s’inscrit maintenant durablement dans le paysage politique : l’essor des sociétés militaires privées qui font ouvertement suite aux activités plus camouflées du mercenariat censé occulter les implications étatiques. Ce sont ainsi plusieurs centaines d’entreprises qui réalisent un chiffre d’affaires annuel supérieur à 100 milliards de dollars et opèrent dans une cinquantaine de pays. L’armée des États-Unis est devenue leur principal client. L’Irak s’est transformé en terrain d’action de ce nouveau marché de la guerre dont les scandales qui l’entourent montrent les connivences coupables avec les pouvoirs publics aux États-Unis et l’intrusion massive de la finance globalisée.
Légalité et légitimité du pouvoir en écosse depuis le vote Brexit
Authors: Duclos Nathalie
Published: December 2022

Le Brexit soulève en Écosse des questions fondamentales qui ont trait au pouvoir et à la légitimité démocratique. Qui a aujourd’hui mandat pour parler et agir au nom de ce pays qui a largement voté en faveur du maintien dans l’UE : le gouvernement central de Londres ou le gouvernement local d’Édimbourg ? Si les deux peuvent légalement prétendre au statut de représentants de l’Écosse, dans la pratique, leurs positions sont totalement incompatibles. C’est donc une bataille des légitimités qui fait aujourd’hui rage en Écosse, chacun s’estimant «mandaté» à prendre des décisions fondamentales dont va dépendre l’avenir politique et constitutionnel du pays, que ce soit la sortie de l’UE ou l’organisation d’un nouveau référendum d’autodétermination. Cette bataille sera décisive, car quel pourrait être l’avenir à long terme de l’Écosse dans un Royaume-Uni dont le gouvernement aurait perdu sa légitimité à la gouverner ?
La spécialisation internationale de la France dans la défense et ses enjeux européens
Authors: Serfati Claude
Published: December 2022

L’espace mondial est configuré par les dynamiques d’accumulation du capital et les transformations du système interétatique. Depuis la fin des années 2000, il a été profondément transformé dans ses composantes économiques et géopolitiques. Dans ce nouveau contexte, le positionnement international de la France est caractérisé par un affaiblissement de ses performances économiques et un rebond militaro-sécuritaire indéniable. Les efforts des gouvernements français, intensifiés par E. Macron, pour consolider la défense européenne visent à renforcer la spécialisation internationale de la France dans le militaire. L’Union européenne demeure cependant un ensemble composite marqué par de profondes divergences qui se manifestent en particulier au sein du «couple» franco-allemand.

Pada GKJ Salatiga Selatan pendeta tidak menempati posisi sebagai pemimpin secara organisatoris, ketua majelis. Pendeta terikat dan diatur oleh sistem birokrasi di dalam gereja, termasuk dalam mekanisme pengambilan keputusan. Berdasarkan data yang diperoleh pada GKJ Salatiga Selatan, pendeta memiliki peranan sebagai pengajar, penengah, dan konselor pastoral dalam pengambilan keputusan. Ketiga peranan ini memberikan pengaruh dalam pengambilan keputusan etis-teologis di GKJ Salatiga Selatan. Adapun salah satu ciri khas dari proses pengambilan keputusan etis di GKJ Salatiga Selatan adalah musyawarah. Musyawarah diyakini sebagai salah satu langkah untuk menemukan kehendak Allah dalam pengambilan keputusan etis-teologis di GKJ Salatiga Selatan. Selain itu, musyawarah juga membantu majelis gereja menyelesaikan dilema moral yang dialami secara individu ketika akan mengambil sebuah keputusan.  Keputusan yang diambil diharapkan adalah keputusan etis-teologis yang sesuai dengan kehendak Allah, tidak menentang nilai-nilai ajaran Yesus, khususnya nilai kasih. Indikator dari keputusan yang diambil merupakan keputusan yang etis-teologis atau tidak adalah dengan melihat dampak dari keputusan tersebut. Jika suatu keputusan berdampak positif maka keputusan tersebut dinilai benar dan sesuai dengan kehendak Allah, begitupun sebaliknya. Tujuan dari penelitian ini untuk mendeskripsikan dan memberikan tinjauan etis-teologis terhadap peran pendeta dalam pengambilan keputusan di GKJ Salatiga Selatan. Penelitian ini menggunakan metode kualitatif dengan pengumpulan data melalui wawancara dan studi pustaka.
Kazak Türkçesindeki “Bar” ve “Joq” İfadelerinin Türkiye Türkçesine Aktarımı Meselesi
Authors: ÖZDEMİR Serdar
Published: December 2022

Türkiye Türkçesi gramerciliğinde cümleler yüklemin türü itibariyle isim ve fiil cümlesi olarak iki gruba ayrılırken Kıpçak grubunda yer alan Kazak Türkçesi gramerciliğinde ise cümleler yüklemin türüne göre gruplandırılmaz. Kazak Türkçesinde “bayandavış” yani yüklem unsuru, isim ve fiil olmasına göre iki gruba ayrılır. Bu makalede Kazak Türkçesindeki isim yüklem unsurlarından olan “bar” ve “joq” ifadelerinin Türkiye Türkçesine nasıl aktarılabileceği meselesi işlenmiştir. Kazak Türkçesindeki “bar” ve “joq” yüklemlerinin Türkiye Türkçesine her zaman “var” ve “yok” şeklinde aktarılamayacağı, cümlenin bağlam esasına ve / veya aldığı takıya dayalı olarak bu ifadelerin “gibi görünüyor /-e benziyor”, “-mIş gibi / -AcAk gibi / -yor gibi”, “-mIş değil”, “-dIğI yok”, “gibi değil / -e benzemez”, “ol-” vb. çok farklı şekillerde de dilimize aktarılabileceği edebî eserlerden alınan örnekler vasıtasıyla gösterilmiştir. Ayrıca makalede Kazak Türkçesinde bir isim yüklem unsuru olan “bar” ifadesini içeren bazı cümlelerin Türkiye Türkçesine yine cümlenin bağlam esasına dayalı olarak fiil cümlesi şeklinde de aktarılabileceği hususu örnek cümleler vasıtasıyla ortaya konmuştur.

Objetivou-se por este trabalho determinar o tamanho ótimo de parcela (top) para experimentos com mudas de mamoeiro ‘Golden THB’ a partir dos dados de avaliação de seis características das mudas produzidas em tubetes. As mudas foram obtidas na Caliman Agrícola S.A. e avaliadas no laboratório de Melhoramento de Plantas, no prédio de pós-graduação em Agricultura Tropical da Universidade Federal do Espírito Santo, no campus São Mateus. Foram avaliadas ao todo 384 mudas em quatro épocas do ano, sendo 96 mudas avaliadas em setembro de 2015, 96 em dezembro de 2015, 96 em março de 2016 e 96 em junho de 2016, sendo analisadas as seguintes características: altura da parte aérea, diâmetro do coleto, peso da matéria seca da parte aérea, da raiz e total e o índice de qualidade de Dickson. Foram utilizados os métodos da máxima curvatura modificado, em sua forma original segundo Meier & Lessman e com simulação bootstrap para determinar o top. Os métodos de Meier & Lessman e simulação bootstrap apresentaram resultados semelhantes entre si para cada característica, porém as características apresentaram top diferentes entre elas e entre as épocas de avaliação. Para contemplar experimentos com mudas de mamoeiro THB, em qualquer época do ano, avaliando-se apenas características não destrutivas são recomendadas cinco mudas por parcela e para avaliar características destrutivas, dez mudas por parcela.
