Compact Image-Style Transfer: Channel Pruning on the Single Training of a Network
Authors: Kim Minseong , Choi Hyun-Chul
Published: November 2022

Recent image-style transfer methods use the structure of a VGG feature network to encode and decode the feature map of the image. Since the network is designed for the general image-classification task, it has a number of channels and, accordingly, requires a huge amount of memory and high computational power, which is not mandatory for such a relatively simple task as image-style transfer. In this paper, we propose a new technique to size down the previously used style transfer network for eliminating the redundancy of the VGG feature network in memory consumption and computational cost. Our method automatically finds a number of consistently inactive convolution channels during the network training phase by using two new losses, i.e., channel loss and xor loss. The former maximizes the number of inactive channels and the latter fixes the positions of these inactive channels to be the same for the image. Our method improves the image generation speed to be up to 49% faster and reduces the number of parameters by 20% while maintaining style transferring performance. Additionally, our losses are also effective in pruning the VGG16 classifier network, i.e., parameter reduction by 26% and top-1 accuracy improvement by 0.16% on CIFAR-10.

Authors: Majdi Nasab Navid , Kilby Jeff , Bakhtiaryfard Leila
Published: November 2022

This paper evaluates the feasibility of using wind power for power supply to coastal communities isolated from the main supply grid. The case study is Stewart Island, where the cost of electricity provided by a central diesel power station is higher than the grid network in New Zealand. The Princeton Ocean Model (POM) conducted by MetOcean Solutions Limited (MSL) is used to find Foveaux as an optimized site for generating wind power. Global Wind Atlas is used to plot the wind rose of current wind patterns in New Zealand. In the next step, wind speed data from each site are imported from the NASA database to WRPLOT view software and Homer Pro to find wind frequency distribution and output power in the area. The maximum annual power can be seen in WSW (32,299 kW hours/year), SW (20,111 kW hours/year) and W (15,622 kW hour/year) directions, respectively.

Published: November 2022

Exploration is an important aspect of autonomous robotics, whether it is for target searching, rescue missions, or reconnaissance in an unknown environment. In this paper, we propose a solution to efficiently explore the unknown environment by unmanned aerial vehicles (UAV). Innovatively, a topological road map is incrementally built based on Rapidly-exploring Random Tree (RRT) and maintained along with the whole exploration process. The topological structure can provide a set of waypoints for searching an optimal informative path. To evaluate the path, we consider the information measurement based on prior map uncertainty and the distance cost of the path, and formulate a normalized utility to describe information-richness along the path. The informative path is determined in every period by a local planner, and the robot executes the planned path to collect measurements of the unknown environment and restructure a map. The proposed framework and its composed modules are verified in two 3-D environments, which exhibit better performance in improving the exploration efficiency than other methods.

Published: November 2022

China is the world’s third-largest producer of sugarcane, slightly behind Brazil and India. As an important cash crop in China, sugarcane has always been the main source of sugar, the basic strategic material. The planting method of sugarcane used in China is mainly the pre-cutting planting mode. However, there are many problems with this technology, which has a great impact on the planting quality of sugarcane. Aiming at a series of problems, such as low cutting efficiency and poor quality in the pre-cutting planting mode of sugarcane, a sugarcane-seed-cutting device was proposed, and a sugarcane-seed-cutting system based on automatic identification technology was designed. The system consists of a sugarcane-cutting platform, a seed-cutting device, a visual inspection system, and a control system. Among them, the visual inspection system adopts the YOLO V5 network model to identify and detect the eustipes of sugarcane, and the seed-cutting device is composed of a self-tensioning conveying mechanism, a reciprocating crank slider transmission mechanism, and a high-speed rotary cutting mechanism so that the cutting device can complete the cutting of sugarcane seeds of different diameters. The test shows that the recognition rate of sugarcane seed cutting is no less than 94.3%, the accuracy rate is between 94.3% and 100%, and the average accuracy is 98.2%. The bud injury rate is no higher than 3.8%, while the average cutting time of a single seed is about 0.7 s, which proves that the cutting system has a high cutting rate, recognition rate, and low injury rate. The findings of this paper have important application values for promoting the development of sugarcane pre-cutting planting mode and sugarcane planting technology.
Synergy Masks of Domain Attribute Model DaBERT: Emotional Tracking on Time-Varying Virtual Space Communication
Authors: Wang Ye , Chen Zhenghan , Fu Changzeng
Published: November 2022

Emotional tracking on time-varying virtual space communication aims to identify sentiments and opinions expressed in a piece of user-generated content. However, the existing research mainly focuses on the user’s single post, despite the fact that social network data are sequential. In this article, we propose a sentiment analysis model based on time series prediction in order to understand and master the chronological evolution of the user’s point of view. Specifically, with the help of a domain-knowledge-enhanced pre-trained encoder, the model embeds tokens for each moment in the text sequence. We then propose an attention-based temporal prediction model to extract rich timing information from historical posting records, which improves the prediction of the user’s current state and personalizes the analysis of user’s sentiment changes in social networks. The experiments show that the proposed model improves on four kinds of sentiment tasks and significantly outperforms the strong baseline.

Published: November 2022

Academics, business leaders, and policymakers are paying more and more attention to sustainable development. The influence of external forces on sustainable development practices, which could predict green innovation, is, however, still unexplored. This paper seeks to explore the role of external pressures on sustainable development practices in the driving of green innovation in Saudi Arabia. We took a quantitative approach through an online survey to collect the required data from manufacturing companies in Saudi Arabia. Structural equation modelling was used to analyse the data. The results revealed that institutional pressures (i.e., governance pressure, customer pressures, and competitive pressure) are key drivers of sustainable development practices and green innovation. They also indicated that sustainable development practices (i.e., environmental sustainability, social sustainability, and economic environmental sustainability) have a significant influence on green innovation. Our findings lead us to propose that green innovation is influenced by external pressures and sustainable development practices.
The Electro-Fenton Process for Caffeine Removal from Water and Granular Activated Carbon Regeneration
Authors: Gadi Nadia , Boelee Nadine C. , Dewil Raf
Published: November 2022

The electro-Fenton process (EF) has faced major challenges, including mass transfer limitations. When the targeted pollutants are present in water at very low concentrations, the degradation kinetics are slower than desired, which leads to high energy consumption. To overcome this drawback, coupled adsorption on activated carbon (AC) and the EF process can be performed. Therefore, the compounds can be preconcentrated on AC before elimination by the EF process. As such, in this study, batch experiments were conducted using low-cost granular activated carbon (GAC) packed in a stainless-steel mesh for the adsorption of caffeine. Once saturated, GAC is used as a cathode during the EF process, where the adsorption capacity is regenerated. This approach allows the regeneration of the AC for multiple cycles and the degradation of the desorbed compounds. The EF process was studied to this end, for the purposes of the removal of caffeine as a model compound. The main goals of this work are (i) to study the removal of caffeine from water in three different matrices and (ii) to regenerate GAC by using the EF process. The results reported in this study show that it is possible to achieve caffeine degradation up to 95%, 100%, and 100%, and a mineralization up to 70%, 72%, and 76% in pure water, simulated wastewater, and wastewater effluent, respectively. In the regeneration process, total elimination of the desorbed caffeine was achieved, and a regeneration efficiency of 50% was obtained for the first cycle. The results confirm the ability of the EF process to achieve regeneration of AC loaded with caffeine.

Published: November 2022

In engineering education, traditional teaching approaches cannot sufficiently help students to learn electric vehicle (EV) concepts. In this study, the design of an educational test setup including all the components and all dynamics of EVs is implemented, and case studies for engineering education with practical applications are discussed. The proposed test and training platform not only provides hands-on experience for engineering students, but also the opportunity for expert users to test their own designed algorithms on the test setup through a computer and human–machine interface device. The aim of the study is to show students the effects of road slope, vehicle weight and energy recovery parameters on a light EV. In this context, five case studies have been carried out by the students, and a survey was conducted with them. The survey results show that the test setup can help them better comprehend any EV system and develop their professional knowledge and skills.

Published: November 2022

Quantifying the spatiotemporal variations of basin-scale surface water (SW)–groundwater (GW) interactions is vital for the conjunctive management of water resources in the basin. In this study, an integrated hydrological model (SWAT-MODFLOW) is used to simulate the SW–GW system in the Huashan Basin. The numerical model was calibrated and validated using the streamflow observations of the watershed outlet and the groundwater levels of the long-term monitoring wells from 2016 to 2020 in the study area. The model results show that the SWAT–MODFLOW can achieve a better fit for the streamflow discharge, compared with the results in the single SWAT model, with R2 (coefficient of correlation) and NSE (Nash-Sutcliffe efficiency coefficient) of 0.85 and 0.83, respectively. The water table fitting results indicate that R2 and RMSE can reach 0.95 and 0.88, respectively. The water budgets analysis demonstrates that the average rate (0.5281 m3/s) of GW abstraction to SW is larger than the rate (0.1289 m3/s) of SW recharge to GW. Moreover, the exchange rate of SW and GW gradually reaches a peak value from June to August, and the lowest value is shown in April, for each hydrological year. Based on the IPPC6 CanESM5 dataset supplied by the Canadian Climate Centre, the regional precipitation scenario subject to climate change was predicted by the ASD (Auto Statistical Downscaling Model) a statistical downscaling method, under the climate scenarios of SSP2_4.5 and SSP5_8.5. The SW–GW interaction pattern was modeled under the future scenarios in the study area. The current (2016–2020) average annual rate of the SW–GW interaction is considered as the base value. Subject to the SSP2_4.5 scenario, the average exchange rate of the SW recharge to GW is 0.1583 m3/s, which is an increase of 22.8%. The average exchange rate of the GW discharge to SW is 0.5189 m3/s which is a reduction of 0.017%. Subject to the SSP5_8.5 scenario, the average exchange rate of SW recharge to GW is 0.1469 m3/s, which is an increase of 14.7%. The average exchange rate of the GW discharge to SW is 0.5953 m3/s, which is an increases of 12.7%. The results can assist in water resource management in the basin, by identifying potential locations of nutrient transport from the aquifer to the river, as well as changes in spatial variability under future climatic conditions.

Authors: Omodero Cordelia Onyinyechi
Published: November 2022

The gross social underdevelopment in Nigerian communities and villages is the underlying reason for investigating the effectiveness of VAT revenue transfers to states and local governments in providing the necessary social and community development services to meet the needs of the entire populace. This study examined the impact of VAT revenue devolution on social development in Nigeria from 1995 to 2021, with a focus on community welfare, making use of secondary data retrieved from the Central Bank of Nigeria’s statistical archive. In analyzing the data, we used an ex post facto research design and a cross-sectional econometric approach. The study examined the relationship between variables and included a trend analysis, a causality evaluation, and a regression analysis to determine the impact of VAT transfer on social welfare in Nigeria. According to the findings, VAT transfer to states has a positive relationship with social development, and the effect is both significant and beneficial at the 0.01 level. Local governments’ share of VAT collection, on the other hand, has an intangible positive effect on social development at the 0.05 degree of importance. As a result, we concluded that VAT revenue autonomy is now required in Nigeria. The study strongly advocates for the total transfer of revenue receipts to states and local governments for the benefit of society.

Published: November 2022

According to the new development pattern, implementing the development strategy driven by scientific and technological innovation (STI) is an important measure for each region to improve the quality of regional economic development. Exploring the effect of STI on the regional high-quality economic development (HED) is helpful to break the bottleneck and enhance the momentum of regional economic development. The Yangtze River Delta, located in the east coast of China, is the frontier of STI and economic development. Based on theoretical analysis, this paper uses the entropy method to calculate the STI index of the Yangtze River Delta from 2009 to 2018, and systematically investigates the impact of STI on HED in Yangtze River Delta by using two-way fixed effect, spatial Dubin model, panel threshold model and moderation effect model. The research finds that: First, under the control of other factors, STI has significantly promoted the HED of Yangtze River Delta region, while it also produces a spatial spillover effect. Second, the impact of STI on HED in the Yangtze River Delta has a double threshold effect based on the advanced industrial structure. Third, the analysis of adjustment mechanism shows that the scale of higher education has a positive adjustment effect in the relationship between STI and HED. Fourth, with the further analysis of regional heterogeneity, the economic effect of STI in central cities is significantly greater than that in noncentral cities. These findings provide theory-based direction and policy inspiration for improving the institutional mechanism of STI and accelerating the promotion of HED in Yangtze River Delta region.

Authors: Li Yi , Li Zhiyang
Published: November 2022

While the e-commerce logistics industry is developing rapidly, its sustainable development has received certain attention. The ultimate goal of sustainable development is to achieve common, coordinated, fair, efficient, and multi-dimensional development. To promote the sustainable development of logistics, the automation technology of warehousing is undoubtedly an excellent breakthrough, since the automation technology can not only make the warehousing system efficient and with a low-error rate, but also affect the energy consumption of the warehousing system. This paper studies the Shuttle-Based Storage and Retrieval System (SBS/RS) in automated warehousing. Moreover, the paper classifies the existing literature into three categories: Physical design (including depth, configuration, and number of tiers); control strategy (including scheduling rules, storage strategies, scheduling command, and interference); and performance evaluation (including throughput, time, and energy). These categories are all factors that warehouse designers must consider when designing a system. Finally, this paper proposes future research directions for SBS/RS: Adding speed metrics, limiting buffer size, targeting space constraints, applying four-way shuttles, and increasing the carrying capacity of a single machine.

At present, scientific and technical activities (STA) play a fundamental role in the creation of new knowledge necessary for the realisation of the goals of sustainable economic growth. The purpose of the research is to assess STA in countries of the world and Ukraine as well as to analyse the impact of STA on their sustainable economic growth. For the assessment of STA of world countries, we have developed a composite indicator (Index of STA–ISTA) based on two sub-indices (Potential of STA and Results of STA) and a set of partial indicators. The study is carried out using a theoretical and methodological approach that includes five research stages: calculating the ISTA of world countries with their subsequent ranking; assessing the impact of the ISTA on the economic growth of world countries; evaluating the correlations between the ISTA, the Global Innovation Index (GII), and the Human Development Index (HDI); breaking down world countries into groups with the help of cluster analysis, using data on the ISTA, GII, HDI; assessing and analysing the importance of environment-related technologies and innovations in ensuring the economic growth of countries of the world. According to the results of the study, the importance of STA in ensuring sustainable economic growth of countries of the world was confirmed. The use of cluster analysis to group countries of the world in terms of the level of STA made it possible to identify three clusters of countries: leaders, potential leaders, and catching-up countries. It has been proven that in order for a country to achieve leadership in terms of STA, it is important to harmoniously combine efforts to support and develop its scientific potential as well as to create principles for the implementation of scientific achievements in innovation activities to ensure its economic growth and improve the living standards of its population. Besides, the analysis allowed proving the existence of a moderately positive impact of the development of environment-related technologies and innovations on the acceleration of innovative development, improvement of the quality of life of the population, and the growth of GDP per capita.

Published: November 2022

To meet the engineering requirements of long-distance and high-precision elevation transfer under adverse sea conditions, a new structure for a combined survey platform based on the basic principle of vibration reduction and isolation is designed in this paper. The combined survey platform uses the barrier effect of the external support system on the wave-current load to reduce the influence of the wave-current load on the internal support system and the platform, so it can maintain good performance, even in harsh sea conditions, under the premise of no collision between the internal and external support systems. The expected working performance of the structure was verified by numerical simulation, and the influence of the layout, structure size, waves, and water flow on the working performance of the structure was quantitatively analyzed. The results show that: (1) the external support system can better realize the barrier effect of the wave-current load and significantly reduce the influence of the wave-current load on the internal support system and platform; (2) for the independent combined survey platform, when the pile diameters of the internal and external support systems are 0.8 m and 1.2 m and the wall thicknesses are 11.0 mm and 12.0 mm, respectively, the period of the wave is 8.0 s, the water depth is 20.0 m, the speed of water flow is 1.0 m/s, and the wave height is 4.0 m, then the maximum variation of the vertical angle of the platform is only 19.3″; (3) for the attached combined survey platform, the lateral stiffness of the external support system is increased and the displacement of the external support system is significantly reduced because the external support system is connected with the cushion cap through the attachments; therefore, the structure size of the survey platform can be greatly reduced.

Authors: Wen Wen , Zhang Wenhui
Published: November 2022

Most existing research on the vector road network is based on GPS trajectory travel information extraction, and urban GPS trajectory data are large and difficult to obtain. Based on this, this study proposes a road network extraction method based on network map API and designs a vector road network based on an improved image-processing algorithm using trajectory data. Firstly, a large number of trajectory data are processed by hierarchical rasterization. The trajectory points of the regional OD matrix are obtained by using the map API interface to generate the trajectory. Then, the image expansion processing is performed on the road network raster image to complete the information loss problem. The improved Zhang–Suen refinement algorithm is used to refine the idea to obtain the road center line, and the vector road network in the study area is obtained. Finally, taking the Harbin City of Heilongjiang Province as an example, compared with the road network of the network map, it has been demonstrated that using this technology may improve the traveler experience and the sustainability of urban traffic flow while reducing the number of manual procedures required, performing online incremental rapid change detection, and updating the present road network at a cheaper cost.
Decadal Variation of Polycyclic Aromatic Hydrocarbons (PAHs) in an Area Contaminated by Coal Gangue Dump: Emphasis on Concentration, Profile, Source and Carcinogenic Risk
Authors: Yang Yanli , Zhang Minmin , Zhao Qiaojing , Panchal Balaji , Wang Jinxi , Bian Kai , Sun Yuzhuang
Published: November 2022

Polycyclic aromatic hydrocarbons (PAHs) are recognized as carcinogens that pose a severe threat to human health. Research on the temporal variation of PAHs was confined to monthly and seasonal investigations, and a longer timescale study remained inadequate until recently. Therefore, this study focuses on the decadal variation of PAHs in environmental media contaminated by a coal gangue dump in the Jiulong Coal Mine, Fengfeng, China. The results show that the total concentrations of PAHs have sharply declined compared to the past. The result of the paired-sample t-test indicates that several individual PAHs have obviously changed in concentration with statistical significance (p < 0.05). Moreover, proportions of medium-molecule weight PAHs increase with statistical significance (p < 0.01) when compared to the past. Various diagnostic ratios suggest that PAHs in previous samples are mainly derived from weathering products of coal gangue and vehicle exhaust, while PAHs in the present samples are dominated by those originating from pyrogenic sources. Calculation of incremental lifetime cancer risks (ILCRs) indicates high carcinogenic risk despite a considerable decrease in ILCR values by 2 to 3 orders of magnitude. It shows that recent measurements conducted by the local government do weaken the contamination of coal gangue dumps, but more attention to pyrogenic PAHs is necessary.
Analysis of the Failure Characteristics and Main Controlling Factors of Surrounding Rocks Using the Standard Specimen with a Pre-Existing Hole
Authors: Wu Zheng , Li Jun , Zhang Wen-Long , Li Chen
Published: November 2022

To analyze the relationship between the butterfly-shaped plastic zone and stress in the rock with a single hole, we investigated the influence law of four factors, namely, the shape of the hole, the loaded confining pressure value, the bidirectional stress ratio, and the hole location on the volume of the butterfly-shaped plastic zone of the standard specimen with a single hole based on the orthogonal test and numerical simulation. The results show that: (I) The bidirectional stress ratio has a significant effect on the size of the plastic zone of the rock with a single hole, while the shape of the hole has no effect. (II) The basic value of confining pressure can weaken the sensitivity of the bidirectional stress ratio required to generate the butterfly-shaped plastic zone, that is, when the confining pressure value increases, the bidirectional stress ratio required to generate the butterfly-shaped plastic zone decreases, but there is always a certain value for the infinite expansion of the plastic zone. (III) The plastic zone of the rock with a single hole has a butterfly-shaped invariance, which means that the failure form of the surrounding rock around the hole will eventually evolve into a butterfly-shaped plastic zone under the state of a non-uniform stress field that reaches a certain bidirectional stress ratio. The research results of this paper have guiding significance for the stability control of the surrounding rock in underground engineering under the non-uniform stress field environment.

Several technical factors contribute to the flow of cuttings from the wellbore to the surface of the well, some of which are fundamentally due to the speed and inclination of the drill pipe at different positions (concentric and eccentric), the efficacy of the drilling mud considers plastic viscosity (PV) and yield point (YP), the weight of the cuttings, and the deviation of the well. Moreover, these overlaying cutting beds breed destruction in the drilling operation, some of which cause stuck pipes, reducing the rate of rotation and penetration. This current study, while it addresses the apropos of artificial intelligence (AI) with symmetry, employs a three-dimensional computational fluid dynamic (CFD) simulation model to validate an effective synthetic-based mud-drilling and to investigate the potency of the muds’ flow behaviours for transporting cuttings. Furthermore, the study examines the ratio effects of YP/PV to attain the safe transport of cuttings based on the turbulence of solid-particle suspension from the drilling fluid and the cuttings, and its velocity–pressure influence in a vertical well under a concentric and eccentric position of the drilling pipe. The resulting CFD analysis explains that the YP/PV of SBM and OBM, which generated the required capacity to suspend the cuttings to the surface, are symmetric to the experimental results and hence, the position of the drill pipe at the concentric position in vertical wells required a lower rotational speed. A computational study of the synthetic-based mud and its potency of not damaging the wellbore under an eccentric drill pipe position can be further examined.

Published: November 2022

This article focuses on the boundary layer for an axisymmetric flow and heat transfer of a nanofluid past a moving slender needle with single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). In this study, the streamlines of the flow are symmetrically located along the needle’s surface. Water and kerosene are two types of base fluids that are considered in this study. This analysis is presented with needle thickness, the ratio of velocity, nanoparticle volume fraction, and Prandtl number. The partial differential equations (PDEs) are transformed into dimensionless ordinary differential equations (ODEs) by adopting relevant similarity transformations. The bvp4c package is implemented in MATLAB R2018a to solve the governing dimensionless problems numerically. The behaviors of various sundry variables on the flow and heat transfer are observed and elaborated further. The magnitude of the skin friction, heat transfer rate, as well as velocity and temperature distributions are demonstrated in graphical form and discussed. It is worth mentioning that kerosene-based CNTs have the largest skin friction coefficient and heat transfer rate compared to water-based CNTs. The thin wall of the needle and the single-walled carbon nanotubes also contributes to high drag force and heat transfer rate on the surface. It is revealed from the stability analysis that the first solution exhibits a stable flow. Obtained results are also matched with the present data in the restricting situation, and excellent agreement is noticed.

ПРАВОВИЙ СТАН КАРАНОСТІ
Authors: Степанюк А.
Published: November 2022

У науці кримінального права караність розглядається як загроза застосування покарання, як властивість потенційної кримінальної відповідальності. На відміну від такого підходу ми вважаємо, що правовий стан караності є складовою частиною реальної кримінальної відповідальності, результатом втілення у життя державного примусу, фактичним обмеженням прав і свобод засудженого під час відбування покарання, призначеного за обвинувальним вироком суду. Дослідженню цього правового феномену, який має місце під час відбування покарання, у науці кримінального і кримінально-виконавчого права до цього часу належна увага не приділялась. Поняття правового стану караності і правового статусу засуджених не співпадають. У правовому стані караності можна розглядати дві складові: правову і моральну. Правова полягає у наявних у реальній дійсності обмеженнях прав і свобод засудженого, які передбачені кримінальним законом і обвинувальним вироком суду, і за якісні і кількісні параметри цих обмежень, органи і установи, уповноважені на виконання вироку, не повинні виходити через обов’язковість вироку суду. Моральна складова стану караності знаходить свій прояв у тих прикрощах, муках, стражданнях, яких зазнає покарана особа у результаті застосування державного примусу під час відбування покарання. Європейські в’язничні правила, Мінімальні стандартні правила ООН стосовно поводження з ув’язненими (Правила Нельсона Мандели), виходять з того, що обвинувальний вирок суду, який передбачив ув’язнення, уже завдав страждань, тому тюремна адміністрація не повинна під час поводження з ув’язненими посилювати їх страждання шляхом додаткових обмежень прав і свобод. Якщо у міжнародних документах йдеться про поводження з ув’язненими, то у вітчизняному кримінально-виконавчому законодавстві регулюється виконання покарань. Виконання покарань і поводження із засудженими між собою не співпадають не тільки за формою, але й за змістом. В Україні не повинно бути органів і установ виконання покарань, а мають бути органи і установи виконання вироку суду. На зміну виконанню покарань із реалізацією державного примусу у позасудовій діяльності має прийти поводження із засудженими, яке передбачає підтримку осіб, вже покараних обвинувальним вироком суду, врахування особливостей різних категорій правопорушників з метою найбільш ефективного задоволення їх потреб; надання засудженим соціальної допомоги для полегшення реінтеграції у вільне суспільство після звільнення.

A partir da produção dos protótipos de itens digitais, realizou-se uma análise qualitativa sobre o design de itens digitais e sua possibilidade de aplicação em avaliações de larga escala. Como resultados parciais, aponta-se que a produção de itens digitais permite a exploração de suportes multimídia e hipermídia, que permitem a avaliação de habilidades de compreensão da escuta, que não são consideradas em instrumentos de avaliação impressos.
Du littoral. Essai d'identification
Authors: Bousquet Bernard
Published: November 2022

In this essay, the author describes coastal landscapes since XVIIe century. He tries to show that human glance on the coast was different at each period. To-day, coastal zones are increasingly under development pressure and all the forms of management and conservation have been changed. A model of each stage is purposed.
Fixer le plan ou gérer le profil : l’exemple du Sillon du Talberv
Authors: Pinot Jean-Pierre
Published: November 2022

Depuis près de trente ans, la crainte que le Sillon du Talberv, en Pleubian, Côtes d'Armor, ne se rompe et cesse ainsi de protéger contre les houles de Nord-Ouest les littoraux de Pleubian, de Bréhat et de la presqu'île paimpolaise a conduit à entreprendre des travaux lourds de fixation que l'auteur a suivis de bout en bout.

Le Sillon du Talberv était une flèche de sable (près de la racine) et de galets (vers la pointe) de 3 km de long, faisant face aux houles atlantiques. Il reculait d'une cinquantaine de mètres par siècle, avec de temps à autre des ruptures, parfois définitives (début du XVIIIème siècle), plus souvent temporaires (second quart du XIXème siècle), et des variations dans la cadence du recul. L'orientation générale variait de quelques degrés, selon les oscillations de la circulation atmosphérique entre ses phases méridiennes et ses phases zonales.

A partir de 1962, la flèche a connu des ruptures ou des submersions qui ont inquiété les riverains des côtes qu'elle protège. Aussi un Syndicat Mixte de Protection s'est-il constitué pour protéger le Sillon. Des sommes importantes ont ainsi été dépensées pour tenter de figer le plan de cette flèche, dont seul le dernier kilomètre évolue aujourd'hui de façon naturelle. Le reste est devenu une sorte de digue inavouée, dont la racine autrefois sableuse est stabilisée par un épi et des enrochements, mais dont les parties centrales, sur lesquelles on a essayé de nombreux types d'enrochements ou d'autres modes d'intervention, ont reculé d'une soixantaine de mètres au cours des vingt dernières années, tandis que, les matériaux s'étalant vers le revers, les submersions sont de plus en plus fréquentes.

Aussi, depuis trois ans, a-t-on renoncé à poursuivre les travaux de fixation du plan de la flèche, en se bornant à des interventions ponctuelles pour corriger les dégradations du profil après chaque tempête. Mais aucun plan de gestion cohérente n'a encore été adopté, et en particulier on laisse toujours des véhicules circuler sur la dune. Il est urgent d'adopter un plan raisonné de gestion, et d'entretien immédiat, qui serait beaucoup moins coûteux que des interventions lourdes et tardives. Mais la structure actuelle des décisions et des financements incite à préférer les gros travaux, tandis que la gestion par la commune de cette partie du Domaine Public Maritime ne se prête guère à l'adoption de mesures impopulaires.
Le terroir. Fin ou renouveau d’une notion
Authors: Brunet Pierre
Published: November 2022

Le terroir est à la charnière des géographies physique et humaine. Mais il n’est pas synonyme de la plus haute qualité, qui dépend aussi d’autres facteurs (espèces cultivées, savoir-faire...). La vogue des produits de qualité amène à s’interroger sur la relation entre le terroir et la qualité des produits agricoles qu’il fournit.
Recherche d’indicateurs "naturalistes" de la limite supérieure du domaine maritime
Authors: Bonnot-Courtois Chantal , Levasseur Jacques-Edouard
Published: November 2022

Cet article a pour objectif d’analyser les possibilités d''utilisation de critères "naturalistes", d’ordre morphosédimentaire et botanique, comme outils de reconnaissance du niveau atteint par les plus hautes eaux, niveau constituant la limite supérieure du Domaine Public Maritime. Après un rappel de la définition du DPM et des pratiques actuelles de sa délimitation, les caractéristiques géomorphologiques des grands types de côtes, naturelles et aménagées, et les données sur l’organisation générale de la végétation littorale ont été comparées à des observations de terrain sur les différentes façades côtières en France métropolitaine. Les résultats obtenus ont permis de dégager les caractères morpho-sédimentaires et botaniques pouvant être considérés comme représentatifs de la limite supérieure de la frange littorale et de déterminer la pertinence de certains critères et les limites de leur utilisation pour la reconnaissance de la limite supérieure du domaine maritime.
L'Homme et l'oiseau sur les littoraux d'Europe occidentale. Appropriation de l'espace et enjeux territoriaux : vers une gestion durable ?
Authors: Chadenas Céline
Published: November 2022

La migration et le stationnement de l'avifaune sur les littoraux d'Europe occidentale font l'objet de nombreuses convoitises. Depuis une trentaine d'années, de nombreuses zones humides ont été réhabilitées et aménagées pour accueillir ces oiseaux à dates fixes (hivernage, nidification). La gestion de ces espaces s'avère être nécessaire pour des populations aux besoins spécifiques et qui tendaient à se raréfier. Mais ce processus n'est pas sans poser de nombreux problèmes d'usage souvent anciens, qui conduisent à s'interroger sur la relation plus globale de l'homme à la nature. Cette étude est menée à partir de sites choisis sur les littoraux de France, de Grande-Bretagne, des Pays-Bas et du Portugal. Ils constituent des zones humides de première importance pour l’avifaune migratrice de l’Ouest paléarctique mais aussi des territoires sur lesquels s'expriment des rapports très divers entre l'homme et l'oiseau.
La diffusion spatiale des services aux entreprises : un révélateur des résistances territoriales aux innovations du système productif
Authors: Liefooghe Christine
Published: November 2022

Depuis les années 1980, l’innovation est le fruit d’une articulation de plus en plus étroite entre industrie et services de haut niveau. Ce nouveau modèle de système productif profite essentiellement aux métropoles, en termes de création d’emplois et de pouvoir de commandement. Les bassins industriels peu diversifiés opposent quant à eux une résistance systémique, spatiale et territoriale, à l’adoption des innovations, en particulier celle que constitue le recours aux services aux entreprises. L’angle théorique de la diffusion spatiale des innovations permet de décrypter ces freins à la modernisation d’un tissu industriel hérité des deux premières révolutions technologiques, celui en l’occurrence de l’ancien bassin houiller du Nord-Pas-de-Calais reconverti.
La communication interculturelle : constitution d'une nouvelle discipline
Authors: Mauviel Maurice
Published: November 2022

Intercultural communication : the creation of a new discipline.

Intercultural communication, a university discipline which appeared in the United-States at the end of the 60s, is the scientific study of the barriers to communication between individuals of different cultures and sub-cultures.

This field of research opened when the two trends relating to culture and communication overlapped from 1965 onwards. Intercultural communication, in order to build up its object and to assert its legitimacy, relies on a certain number of subdisciplines derived from contemporary, cultural anthropology : cognitive anthropology and symbolics in particular. It also gives great importance to the phenomenological alternative which inspires the social theory of today (ethnome-thodology applied to the school sector, for instance).

Intercultural communication is particularly interesting for the world of education, international management and all the institutions concerned with the improvement of interethnic relations.

The intermixing of populations in the world of today will more and more impose the development of serious scientific studies in this field.
Du micro-crédit à la micro-finance : vers une gestionnarisation des pratiques informelles ?
Authors: Metzger Jean-Luc
Published: November 2022

L’auteur montre que le microcrédit, qu’il analyse comme une institution sociale, est l’un des modes d’adaptation des populations pauvres à l’affaiblissement des infrastructures publiques. Les super-acteurs cherchent à le rationaliser pour le rendre plus performant. Ce faisant, ils menacent l’existence du microcrédit dans ses modes de fonctionnement actuels (c’est-à-dire basé sur la confiance entre individus, des engagements réciproques, la solidarité, …). En effet, ces super-acteurs veulent simultanément conserver sa souplesse de fonctionnement – tout en la contrôlant au moyen d''indicateurs quantitatifs -, agir sur l''efficacité économique de ce système autonome, tout en évacuant sa dimension sociale et informelle. L’auteur conclut en montrant que les pratiques des Institutions internationales d’encouragement au développement du microcrédit constituent ce qu’il appelle une «gestionnarisation » des pratiques des populations des pays du Sud, qui se substitue à l’action publique qu’elles contribuent à affaiblir encore.
Interpénétration des civilisations et psychologie des peuples (réédition)
Authors: Bastide Roger
Published: November 2022

Réédition d’un article de Roger Bastide publié en 1950 dans la Revue de psychologie des peuples, revue créée et animée par A. Miroglio, à laquelle Bastide apporta un soutien constant. Dans ce texte, l’auteur veut mettre la psychologie des peuples à l’épreuve de situations dynamiques de rencontre entre les cultures et les mentalités, ce qui l’amène à souligner l’importance des parcours de vie, de l’expérience et des interactions vécues par «l’homme marginal» , placé au cœur des processus migratoires et/ou au confluent de plusieurs cultures, dans la formation des «mentalités». Il dessine ainsi les contours d’un programme de recherche et d’une problématique que la sociologie et l’anthropologie n’ont redécouvert qu’assez récemment, celle de l’articulation entre phénomènes psychiques, parcours biographiques, et grands déterminants sociaux, institutionnels et culturels.
