The role of geological and geotematic mapping has recently come to the forefront in spatial/environmental management. This paper aims to present some cases of boundary extension in the use of contemporary cartographic tools (GIS and WEBGIS). The potential of digital maps and associated databases offers a wide range of applications, responding to the urgent need to make available to users (practitioners in the technical sectors, planners and society as a whole) the most important concepts to concretely achieve better land management, active risk prevention and sustainable resource enhancement. The application of geomorphological maps to issues closer to society can effectively create its approach to more properly technical-scientific issues, fostering a shared awareness, useful in protecting and enhancing the fragile Italian territory. The described experiences focus on GIS, which confirms its effectiveness both for social involvement in environmental issues, and in territorial/environmental management.
地质和地理制图的作用最近在空间/环境管理方面成为最重要的。本文旨在介绍使用现代制图工具(GIS和WEBGIS)进行边界扩展的一些案例。数字地图和相关数据库的潜力提供了广泛的应用,满足了向用户(技术部门的从业人员、规划人员和整个社会)提供最重要概念的迫切需要,以便具体实现更好的土地管理、积极预防风险和可持续地增加资源。将地貌图应用于更接近社会的问题,可以有效地为更适当的技术科学问题创造方法,促进共同意识,有助于保护和加强脆弱的意大利领土。所描述的经验集中在地理信息系统,这证实了它在社会参与环境问题和领土/环境管理方面的有效性。

There is a global consensus among scientists that human-caused climate change is threatening the environment and communities worldwide and that major changes must be implemented to reduce the increasing rate of CO2 emissions. Moreover, environmentally unsustainable practices are both endangering and degrading the quality of life on Earth. One major and often underestimated aspect of this problem is the difference in individual environmental risk perception and evaluation. It is evident that the responsibility for Earth's future lies in the hands of young generations and raising their awareness of environmental issues is a substantial challenge for education institutions. Students need to develop new values, skills and behaviors to foster sustainable development. As institutions of higher education, universities have a major impact on society and play a key role in the development of environmental awareness in young people. The paper describes the results of a survey administered to students in the Cultural Geography B course at the University of Torino. The purpose of the analysis was to determine if there is a relationship between environmental perception, attitude and behavior. The results showed that the students had a good knowledge of and positive attitude to the environment. However, as past studies have already revealed, there is a gap between their awareness and proactive environmental behaviors. Knowledge does not appear to be the only variable needed and other hypotheses should be explored to change the behavior of young generations. This study provides some insights for implementing integrated sustainability processes and engaging students. Moreover, the results will support the structuring of a future Geography course that focuses on sustainable development and environmental risk.
全球科学家一致认为,人类造成的气候变化正威胁着世界各地的环境和社区,必须实施重大变革,以降低二氧化碳排放量的增长速度。此外,环境上不可持续的做法正在危及和降低地球上的生活质量。这一问题的一个主要而又经常被低估的方面是个人对环境风险的认识和评价的差异。显然,地球未来的责任在于年轻一代,提高他们对环境问题的认识是教育机构面临的一项重大挑战。学生需要发展新的价值观、技能和行为来促进可持续发展。作为高等教育机构,大学对社会有重大影响,在培养年轻人的环境意识方面发挥着关键作用。本文描述了一项针对都灵大学文化地理B课程学生的调查结果。分析的目的是确定环境感知、态度和行为之间是否存在关系。结果显示,学生对环境有良好的认识和积极的态度。然而,正如过去的研究已经揭示的那样,他们的意识和积极的环境行为之间存在差距。知识似乎不是唯一需要的变量,应该探索其他假设来改变年轻一代的行为。本研究为实施综合可持续发展过程和吸引学生提供了一些见解。此外,研究结果将支持构建未来以可持续发展和环境风险为重点的地理课程。

E-Learning in Geography: new perspectives in post-pandemic 地理电子学习:大流行后的新视角
IF 1.3 Q4 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2022-01-01 DOI: 10.3934/geosci.2022004

Recent developments in low-cost information technology, fast internet, intelligent terminals, apps that can manage the most varied activities in a professional but simple way, have allowed their diffusion in sectors traditionally reluctant to rapid change. The pandemic crisis caused by Covid-19 and the consequent provisions of social distancing to curb its spread, have also forced the world of education to deal with this modality. Terms such as Distance Learning and Smart Working have forcefully entered the vocabulary and daily life of millions of people. The persistence of the pandemic due to the variants of the virus is convincing even the most reluctant to change that the new "normal" will have to rely on information technology to a greater extent than in the past. In much of the Western world, where culture has long been a thriving economic sector, much has been invested for decades to strengthen and disseminate distance learning activities recognized as economically and socially beneficial. The European institutions have moved in this direction more recently. The author's experience in the last two years in emergency remote education in geography at university level has not always been positive. He therefore felt the urgency to consider adopting existing standards and best practices in order to improve outcomes and achieve effective online geography learning. The evident advantages of adopting good quality e-learning for an extended community would facilitate understanding and acceptance even in the Italian school and academic environment, usually conservative and conformist. In this environment, up to now, many have in fact feared that it could lead to the endorsement of distance learning, viewed with contempt if not really with aversion as it is considered to be of poor quality.
低成本信息技术、快速互联网、智能终端以及能够以专业而简单的方式管理最多样化活动的应用程序的最新发展,使它们得以在传统上不愿快速变革的行业中扩散。由Covid-19引起的大流行危机以及随之而来的社会距离规定以遏制其传播,也迫使教育界应对这种方式。远程学习和智能工作等术语已经进入了数百万人的词汇和日常生活。由于病毒变种造成的大流行持续存在,即使是最不愿意改变的人也相信,新的“常态”将不得不比过去更大程度地依赖信息技术。在西方世界的许多地方,文化长期以来一直是一个蓬勃发展的经济部门,几十年来,人们投入了大量资金来加强和传播被认为对经济和社会有益的远程学习活动。欧洲各机构最近已经朝这个方向迈进。作者在过去两年中从事大学地理应急远程教育的经验并不总是积极的。因此,他感到迫切需要考虑采用现有标准和最佳做法,以改善成果并实现有效的在线地理学习。为更广泛的社区采用高质量的电子学习的明显优势将促进理解和接受,即使在意大利的学校和学术环境中,通常是保守和墨守成规的。在这种环境下,到目前为止,许多人实际上担心这可能导致远程教育的认可,因为远程教育被认为质量很差,因此即使不是真正的厌恶,也会受到蔑视。

Advancement of the TI concept: defining the origin-of-life stages based on the succession of a bacterial cell exit from anabiosis TI概念的进步:根据细菌细胞从复苏中退出的继承来定义生命起源阶段

Now there is a huge variety of scenarios of prebiotic chemical evolution, culminating in the emergence of life on Earth, which demonstrates the obvious insufficiency of existing criteria for a reliable consideration of this process. This article develops the concept of thermodynamic inversion (TI concept) according to which the real succession of the formation of metabolism during the origin of life is fixed in the stages of the exit of a resting bacterial cell from anabiosis (suspended animation), just as the succession of events of phylogenesis is fixed in ontogenesis. The deepest phase of anabiosis considers by us as an intermediate state of a microorganism between non-life and life: it is no longer able to counteract the increase in entropy, but retains structural memory of the previous living state. According to the TI concept, the intermediate state between non-life and life thermodynamically corresponds to the approximate equality of the total contributions of entropy and free energy in prebiotic systems (Sc ≈ FEc). Considering such intermediate state in prebiotic systems and microorganisms as a starting point, the authors use the experimentally recorded stages of restoring the metabolic process when a resting (dormant) bacterial cell emerges from anabiosis as a guideline for identifying the sequence of metabolism origin in prebiotic systems. According to the TI concept, life originated in a pulsating updraft of hydrothermal fluid. It included four stages. 1) Self-assembly of a cluster of organic microsystems (complex liposomes). 2) Activation (formation of protocells): appearance in the microsystems a weak energy-giving process of respiration due to redox reactions; local watering in the membrane. 3) Initiation (formation of living subcells): formation of a non-enzymatic antioxidant system; dawning of the protein-synthesizing apparatus. 4) Growth (formation of living cells—progenotes): arising of the growth cell cycle; formation of the genetic apparatus.
现在有各种各样的生命前化学进化的场景,最终在地球上出现了生命,这表明现有的标准明显不足,无法可靠地考虑这一过程。本文提出了热力学反演的概念(TI概念),根据这一概念,生命起源过程中代谢形成的真正演替是固定在一个静止的细菌细胞从复苏(假死)中退出的阶段,正如系统发生事件的演替是固定在个体发生中一样。复苏的最深阶段被我们认为是微生物在非生命和生命之间的中间状态:它不再能够抵消熵的增加,但保留了以前生命状态的结构记忆。根据TI概念,非生命和生命之间的中间态在热力学上对应于益生元系统中熵和自由能的总贡献的近似相等(Sc≈FEc)。考虑到益生元系统和微生物中的这种中间状态作为起点,作者使用实验记录的恢复代谢过程的阶段,当一个静止(休眠)的细菌细胞从复苏中出现,作为确定益生元系统中代谢起源序列的指导。根据TI的概念,生命起源于热液流体的脉动上升气流。它包括四个阶段。1)有机微系统簇(复杂脂质体)的自组装。2)活化(原始细胞的形成):由于氧化还原反应,在微系统中出现微弱的供能呼吸过程;膜内局部浇水。起始(活亚细胞的形成):非酶促抗氧化系统的形成;蛋白质合成装置的曙光。4)生长(形成活细胞-后代):生长细胞周期的产生;遗传器官的形成

The pandemic due to Covid-19 ushered Italian universities into the world of digital education, with geography being one of the disciplines that derived multiple benefits from a worldwide, technological transition. Our contribution focuses on the Turin experience of Cultural Geography teaching for the degree-courses of Languages and Cultures for Tourism (Undergraduate course) and of International Communication for Tourism (Master's degree-course). It highlights how the combined use of Moodle, WebEx, Google Earth, and Instagram stimulated an interest in a traditionally neglected subject, but also offers food for thought on the use of the same technologies in teaching Italian language, through geography, in US universities.

Artificial coral reefs as a localised approach to increase fish biodiversity and abundance along the North Bali coastline 人工珊瑚礁是增加北巴厘岛海岸线鱼类生物多样性和丰度的本地化方法

Coral reefs face worldwide decline from threats such as climate change, destructive fishing practices, overfishing and pollution. Artificial reefs have shown potential as a method to mitigate localised habitat loss and biodiversity decline on degraded coral reefs. The health of coral reefs in Indonesia and their associated faunal populations have displayed a downward trend in recent decades, and community-managed non-government organisations have started using artificial reefs to restore local degraded reef habitats. In this study, we demonstrate how locally-managed NGOs and communities in north Bali, Indonesia have implemented artificial reef projects, and assess the associated benefits to biodiversity. Using Remote Underwater Video (RUV) over a 3 month period in north Bali, fish assemblages on two artificial reefs of different ages (new and mature) were compared to two nearby natural habitats: degraded sand flats and relatively healthy coral reefs. When compared with a nearby degraded sand habitat, both artificial reefs displayed a significantly higher number of species, which for the mature artificial reef was not statistically different to a nearby coral reef. Community structure was also compared, again showing similarity between artificial reefs and natural coral reefs, but differing in a few species, including specific damselfish and wrasse. This study is one of few which highlight the potential of artificial reef habitat enhancement in Indonesia, and suggests that these structures can provide ecologically equivalent mobile faunal communities to a natural reef on a localised scale. As such, well designed projects may be able to provide some local ecosystem services lost from degraded coral reefs, and become an important focus for coastal communities.
由于气候变化、破坏性捕捞、过度捕捞和污染等威胁,珊瑚礁面临着全球范围内的减少。人工珊瑚礁已显示出作为一种减轻局部栖息地丧失和生物多样性下降的方法的潜力。近几十年来,印度尼西亚的珊瑚礁及其相关动物种群的健康状况呈下降趋势,社区管理的非政府组织已经开始使用人工珊瑚礁来恢复当地退化的珊瑚礁栖息地。在本研究中,我们展示了印度尼西亚巴厘岛北部当地管理的非政府组织和社区如何实施人工珊瑚礁项目,并评估了相关的生物多样性效益。利用远程水下视频(RUV)在巴厘岛北部为期3个月的时间里,将两个不同年龄(新和成熟)的人工珊瑚礁上的鱼类组合与附近两个自然栖息地(退化的沙滩和相对健康的珊瑚礁)进行了比较。与附近退化的沙生境相比,两种人工礁的物种数量均显著增加,成熟人工礁与附近珊瑚礁的物种数量差异无统计学意义。群落结构也进行了比较,再次显示了人工珊瑚礁和天然珊瑚礁之间的相似性,但在一些物种中有所不同,包括特定的雀鲷和濑鱼。这项研究是少数几个强调印度尼西亚人工珊瑚礁栖息地增强潜力的研究之一,并表明这些结构可以在局部范围内提供与自然珊瑚礁生态相当的移动动物群落。因此,设计良好的项目可能能够提供一些因珊瑚礁退化而失去的当地生态系统服务,并成为沿海社区的重要焦点。

This research aims to study the radiation concentration distribution of the old District of Najaf (Iraq), where 15 samples were taken from featured sites in the District, which represents archaeological, religious, and heritage sites. Track detector CR-39 was used to calculate the concentration of three different soil weights for each sample site after being exposed for a month. Geographical information systems (GIS) were used to distribute the radioactive concentration on the sites of the samples, where two interpolation methods, namely the inverse distance weight method (IDW) and the triangle irregular network method (NIT), to study the distribution of the radioactivity concentration. The study showed that the western part of the district, which includes the old cemetery and the areas adjacent to the Najaf water depression, are characterized by a relatively high amount of radioactivity concentration compared to the eastern part, which represent the residential areas, and for all sample weights.
本研究旨在研究纳杰夫(伊拉克)老区的辐射浓度分布,从该地区的考古、宗教和遗产遗址的特色地点采集了15个样本。利用径迹检测器CR-39计算每个样点暴露一个月后三种不同土重的浓度。利用地理信息系统(GIS)对采样点的放射性浓度进行分布,并采用逆距离加权法(IDW)和三角形不规则网法(NIT)两种插值方法对放射性浓度的分布进行研究。研究表明,该地区的西部,包括旧墓地和毗邻Najaf洼地的地区,与代表居民区的东部相比,放射性浓度相对较高,所有样本权重都是如此。

A transverse harmonic seismic wave, which propagates through the upper fractured layer of the Earth towards the Earth's surface, is considered. It is shown that the attenuation of a seismic wave in the Earth's upper crust is due to internal friction, i.e., friction between the sides of micro-fractures. Such a damping mechanism does not work in the deeper layers of the Earth where high lithostatic pressure prevents the movement along fractures. The governing equation for a brittle fractured medium is nonlinear. In the study of wave propagation, an approximate method of harmonic linearization is used. It is shown that internal friction in the upper crust leads to the transformation of a transverse harmonic wave into a shock wave.
考虑了通过地球上部断裂层向地球表面传播的横向谐波地震波。结果表明,地震波在地球上地壳中的衰减是由于内摩擦,即微裂缝两侧之间的摩擦。这样的阻尼机制在地球的深层不起作用,因为那里的高静岩压力阻止了沿裂缝的运动。脆性断裂介质的控制方程是非线性的。在波的传播研究中,采用了近似的谐波线性化方法。结果表明,上地壳的内摩擦使横谐波转化为激波。

In recent months, the COVID-19 pandemic has been fervently considered from the perspective of various disciplines in the scientific community. Many of the proposed approaches are tied to reflections on the imminent and future effects of the pandemic. This contribution begins with a study of the recent past in Italy, analyzing the hurdles in politics that came to light due to the wave of COVID-19 infections worldwide. Particularly, the research considers the criticality of the geographical scale of reference in Italy's political actions. COVID-19 induced a need for the government to interact with people locally, especially through small municipalities in geographically central, inner areas, is emphasized. The main aim of this research is to attribute to this specific COVID-19 disaster the instrumental role of turning on the lights on the need to intervene in the inner areas of Italy, often very neglected. So the focus of the work is on inner areas and the probable catalysis of the political management dynamics that concern them, as an effect of the COVID's impacts. The pandemic is, therefore, only the contingent phenomenon which, in this case, can perhaps accelerate political interventions in inner areas. To explain the reason for this, we show how the vulnerability of inner areas, already generally risky, has become one of the weak links in the chain of protection from COVID-19 in terms of a geographical scattering phenomenon.
近几个月来,科学界从各个学科的角度对新冠肺炎大流行进行了热烈的研究。许多拟议的办法都与对这一大流行病迫在眉睫和未来影响的思考有关。本文首先对意大利近期的历史进行了研究,分析了因全球新冠肺炎感染浪潮而暴露出来的政治障碍。特别是,该研究考虑了意大利政治行动中参考的地理规模的重要性。他强调,新冠疫情促使政府需要与当地民众互动,特别是通过地理位置中心的内陆地区的小城市。这项研究的主要目的是将这一特定的COVID-19灾难归因于打开对意大利内部地区进行干预的必要性的重要作用,这些地区往往被忽视。因此,工作的重点是内部领域,以及与之相关的政治管理动态的可能催化作用,这是COVID影响的结果。因此,大流行病只是一种偶然现象,在这种情况下,这种现象可能会加速内部地区的政治干预。为了解释其原因,我们展示了已经普遍存在风险的内陆地区的脆弱性如何在地理分散现象方面成为COVID-19保护链中的薄弱环节之一。
