The subject of the article concerns vertical urban farms that play an important role in nature-based solutions and ecosystem services for the city. In the face of a changing climate, progressive environmental degradation, and the related loss of agricultural land, vertical farms can be seen as an alternative to traditional agriculture. Woven into the blue-green infrastructure of cities, they may not only constitute a base for food production, but can also create a new valuable ecological, social, and economic hub in contemporary cities, changed by the COVID-19 pandemic. The objective of this paper is to show whether it is possible to introduce various functions which support ecosystem and social services, and whether they affect measurable benefits for urban residents in a large-scale system of solutions in the field of vertical urban agriculture. This research shows that urban vertical farms can perform many functions and bring diverse benefits to the inhabitants of cities. In a multi-scale system, they allow for the creation of patchwork connections, which stabilise a specific city biome in the vertical space.

2006-2010: during these four decisive years in the history of the peace movement, the movement experienced a dramatic eclipse. Within an Israeli society that had grown increasingly nationalist, more attached to symbols of Jewish identity and the memory of the Holocaust, more concerned than ever about security, and less interested in making peace with the Palestinians, the movement was incapable both of promoting a message of peace and taking a stance on the subject of human rights. It seemed apathetic, paralyzed, almost non-existent in the face of the terrible events that marked the period. This chapter shows how and why this eclipse occurred. These years were punctuated by two large-scale military operations, the war in Lebanon in July 2006 and Operation Cast Lead in the Gaza Strip from late 2008 to early 2009. These hostilities caused turmoil in the Israeli collective psychology and the perception of war and peace.

Abstract Research and practice during the last 20 years has shown that urban agriculture can contribute to minimising the effects of climate change by, at the same time, improving quality of life in urban areas. In order to do so most effectively, land use and spatial planning are crucial so as to obtain and maintain a supportive green infrastructure and to secure citizens' healthy living conditions. As people today trend more towards living in green and sustainable city centres that can offer fresh and locally produced food, cities become again places for growing food. The scope of urban agriculture thereby is to establish food production sites within the city's sphere; for example, through building-integrated agriculture including concepts such as aquaponics, indoor agriculture, vertical farming, rooftop production, edible walls, as well as through urban farms, edible landscapes, school gardens and community gardens. Embedded in changing urban food systems, the contribution of urban agriculture to creating sustainable and climate-friendly cities is pivotal as it has the capacity to integrate other resource streams such as water, waste and energy. This article describes some of the current aspects of the circular city debate where urban agriculture is pushing forward the development of material and resource cycling in cities.

City of Melbourne

About 15 years ago the City of Melbourne came up with a scheme that would transform completely the face and the fortunes of the city. At the time the city, like thousands of others around the globe, emptied at night as tens of thousands of commuters decamped in their cars for the suburbs. The Council's Postcode 3000 scheme, launched in 1992, outlined plans to entice residential development back into the city, through financial and technical incentives, technical advice, a review of technical requirements, research and statistical data, promotional events and publicity.It is hard now to believe -walking through the bustling streets lined with converted apartments and thriving businesses -that anyone was ever sceptical about the potential for city living Melbourne-style. The success of Postcode 3000 far exceeded even the most ambitious targets and the City of Melbourne became one of the fastest growing municipalities in the land.With its visionary new Council House 2 (CH2) building , the City of Melbourne is once again planning a lifestyle revolution. This time the subject is sustainability and the target is the construction industry. Using the CH2 office building as a living , breathing example, the Council intends to demonstrate the potential for sustainable technologies to transform the way we approach the design, construction and indeed entire philosophy of our built environment. Just as Postcode 3000 reinvented the city, the City of Melbourne wants to see the CH2 example copied , improved upon and enthusiastically taken up throughout Melbourne and far, far beyond.As before, there are a great many sceptics. The City's approach to this has been to patiently press ahead with construction of its best source of proof -CH2 itself -while actively and energetically encouraging lively debate -from the greatest enthusiasts to the harshest critics alike.

We begin with an image, and a story. Explanation will emerge from what follows. Figure 1 depicts a huge wooden statue of the Virgin Mary, once the figurehead on the prow of a ship, but now on the high altar of the church of Saints Vittore and Carlo in Genoa, and venerated as Nostra Signora della Fortuna. On the night of 16-17 January 1636 a violent storm struck the port of Genoa. Many ships were wrecked. Among them was one called the Madonna della Pieta, which had the Virgin as its figurehead. A group of Genoese sailors bought this image as part of the salvage washed up from the sea. First setting it up under a votive painting of the Virgin in the harbour, they repaired it, had it repainted, and on the eve of Corpus Christi brought it to the church of San Vittore, close by the port. A famous blind song-writer was commissioned to write a song in honour of the image. Sailors and groups of young girls went through the streets of the city singing and collecting gifts. The statue became at once the focus of an extraordinary popular cult, thousands of people arriving day and night with candles, silver crowns, necklaces, and crosses in gratitude for the graces which had immediately begun to be granted. Volleys of mortars were let off in celebration. The affair was managed by the sailors who, in the face of mounting criticism and anxiety from local church leaders, directed devotions and even conducted exorcisms before the image. To stem the gathering tide of visitors and claims of miracles, and to try to establish control, the higher clergy first questioned the identity of the statue (some held it to represent, not the Virgin, but the Queen of England); then the statue was walled up; finally the church was closed altogether. Still, devotees climbed into the church, and large-scale demonstrations of protest were held. The archbishop instituted a process of investigation, in the course of which many eye-witnesses and people who claimed to have experienced miracles were interviewed (giving, in the surviving manuscript, rich detail of their responses to the image). Eventually the prohibition was lifted, and from 1637 until well into the twentieth century devotion to Nostra Signora della Fortuna remained strong, with frequent miracles or graces being recorded. So here we have a cult focused on an image of secular origin, transformed by the promotion of the sailors into a devotional object which roused the enthusiasm of thousands of lay people. It was a cult which, significantly, sprang up at a time of unrest in the city of Genoa, and which thus focused pressing issues of authority. The late 163os witnessed growing tension between factions of ‘old’ and ‘new’ nobility, the latter being marked by their hostility to the traditional Genoese Spanish alliance. Hostilities were played out both within the Senate and in clashes in the streets of the city. The cult of Nostra Signora della Fortuna grew up in this context, but survived and developed in subsequent centuries, attracting devotion from all over Italy.

Purpose The purpose of this paper is to present the varied roles played by the University of Lódz (UL) in maintaining and restoring the natural capital of a city as a driver for sustainable city development. The higher education institution can be perceived as visionary, originator and executor of natural capital projects. Design/methodology/approach The paper analyses three cases performed by the Faculty of Biology and Environmental Protection, UL, in the city of Lódz. The activities are based on different scales ranging from city-wide to local, e.g. river and green infrastructure, and which vary in character from policy planning to implementation. Findings Natural capital projects influence city development on different levels: by the initiation of legal protection, by the implementation of rehabilitation concepts for rivers and by influencing the strategic documents for mid-term and long-term urban development. Originality/value The university has the potential for multidisciplinary engagement in the development of urban sustainability. In large-scale projects, academics play a more conceptual role, in capacity building and knowledge transfer, while in local-scale implementations, their role includes innovation, know-how and technology transfer. Moreover, it may act as a reinforcement hub, by safeguarding and strengthening the natural capital of the city.

Resumo Este artigo trata da forma como professores e alunos do Ensino Médio de uma escola pública da cidade Manaus entendem a discussão sobre a educação sexual e sexualidade em um espaço no qual se busca o conhecimento e aprendizagem. Considerou-se necessário explorar esse tema em face das polêmicas e os tabus envolvidos neste assunto. O profissional da escola responsável por discutir esse assunto com os alunos, na maioria das vezes, é o professor, sendo que poucos possuem capacitação para tratar do assunto. A pesquisa teve como objetivo compreender a percepção dos adolescentes e professores a respeito as atividades voltadas para a sexualidade e educação sexual conduzidas em uma escola pública da cidade Manaus. Esta pesquisa teve uma abordagem qualitativa-quantitativo, caráter descritivo e de campo, sendo o instrumento utilizado, um questionário. A partir dos resultados foi possível identificar que os professores buscam dialogar com a temática com suas respectivas disciplinas, entretanto, o tema ainda gera interpretações equívocas por parte dos alunos, mostrando assim que os professores não estão capacitados adequadamente para a condução dos debates e discussões voltadas para o assunto. Os adolescentes entendem que o debate sobre a sexualidade e educação sexual são importantes para o esclarecimento e redução de preconceitos. Entende-se que esta pesquisa oferece uma reflexão a respeito do assunto para que sejam reformuladas as propostas de educação sexual e discussão da sexualidade no ambiente escolar. Palavras-chave: Preconceitos. Alunos. Professores. AbstractThis article deals with how teachers and high school students from a public school in the city of Manaus understand the discussion about sexual education and sexuality in a space where knowledge and learning are sought. It was considered necessary to explore this theme due to the in the face of controversies and the taboos involved in this subject. The school professional responsible for discussing this subject with students, most of the time, is the teacher, and few have training to deal with the subject. The research aimed to understand the adolescents’ and teachers’ perception regarding activities related to sexuality and sexual education conducted in a public school in the city of Manaus. This research had a qualitative-quantitative, descriptive and field approach, and the instrument used was a questionnaire. From the results it was possible to identify that teachers seek to dialogue with the theme with their respective subjects, however the theme still generates misinterpretations on the part of students, thus showing that teachers are not adequately trained to conduct debates and discussions aimed at the subject. Adolescents understand that the debate about sexuality and sex education is important for clarifying and reducing prejudices. It is understood that this research offers a reflection on the subject so that the proposals for sexual education and the discussion of sexuality in the school environment are reformulated. Keywords: Prejudices. Students. Teachers.

While the Punic Wars (264–146 BC) have been the subject of numerous studies, generally focused on their most sensational aspects (major battles, techniques of warfare, geopolitical strategies, etc.), curiously, the exceptional economic resilience of the Carthaginians in the face of successive defeats, loss of mining territory, and the imposition of war reparations has attracted hardly any attention. Here, we address this issue using a newly developed powerful tracer in geoarchaeology, that of Pb isotopes applied to paleopollution. We measured the Pb isotopic compositions of a well-dated suite of eight deep cores taken in the Medjerda delta around the city of Utica. The data provide robust evidence of ancient lead–silver mining in Tunisia and lay out a chronology for its exploitation, which appears to follow the main periods of geopolitical instability at the time: the Greco-Punic Wars (480–307 BC) and the Punic Wars (264–146 BC). During the last conflict, the data further suggest that Carthage was still able to pay indemnities and fund armies despite the loss of its traditional silver sources in the Mediterranean. This work shows that the mining of Tunisian metalliferous ores between the second half of the fourth and the beginning of the third century BC contributed to the emergence of Punic coinage and the development of the Carthaginian economy.

To solve the problem of difficult face detection in a low illumination vehicle environment, a novel multi-scale retinex color restoration (MSRCR) approach exploiting the RGB three-channel decomposition and guided filtering (MSRCR-3CGF) is proposed. The MSRCR algorithm is employed to remove the artifacts and interference of low-light in the image based on the face detector using a multi-task cascaded convolutional neural network (MTCNN). The enhanced face image is decomposed into RGB, and GF is applied to each channel. The proposed method is tested on three widely used datasets: Dark Face, large-scale CelebFaces attributes (CelebA) and WIDER FACE, and an actual low-light scene in vehicles. The experimental results show that the proposed method suppresses the high-frequency noise of MSRCR, whilst improving the image enhancement and accuracy in the face detection in a low-light vehicle environment.

The Dutch policy on drugs has often been criticized in other countries. It has been claimed that the Netherlands has given up the fight against drugs and does not fulfill its international responsibilities. The purpose of this article is to show that the drug problem is taken seriously in the Netherlands, and plenty of resources are used to deal with it. The Dutch view on the nature of the problem and appropriate ways to treat drug users, however, is different from what is common elsewhere. The object of the study is the drug scene and the administration of drug-related services in Rotterdam. The focus in this article is on the relationship between drug users and the drug control system. The study draws upon observations and documents, and numerous interviews with civil servants, treatment staff, and drug users during a three-week visit in Rotterdam. In Rotterdam there are separate markets for cannabis and hard drugs. About 150 cafes are permitted to sell cannabis products provided they follow the rules: no sales to minors under 18 years of age, no alcohol, no hard drugs, no advertising. Hard drugs are sold illegally in 300-400 apartments located in the older parts of the city. The number of hard drug users is estimated to be 2500 - 4000, and the majority of them are registered in the Rotterdam Drug Information System (RODIS), which makes them eligible to use the services provided by the city for addicted drug users, gamblers, and alcoholics. No legal sanctions relate to smoking of cannabis or to possession of small amounts, whereas large-scale trade, smuggling, and commercial cultivation are criminal activities. Neither is the use of hard drugs or possession for personal use criminalized. The core of the drug problem is seen to be on the one hand the nuisance caused by those addicted hard-drug users who resort to petty crime and threaten the safety of other people, leading to the deterioration of the urban environment, and on the other hand the threat to the economy and politics of the country created by criminal drug organizations. In dealing with drug-related nuisance the aim is harm reduction. The central idea is the normalization of the drug problem. This means that efforts are made to keep drug users in contact with society, instead of pushing them outside by pursuing repressive policies. The threshold to health and social services and to treatment is kept as low as possible. At the same time addicts are held responsible for their behavior, and they are required to follow the regulations of the institutions providing support and treatment. Decisions concerning drug policies in Rotterdam are made at the top level, by the mayor, the public prosecutor, and the chief of police. They are assisted by the aldermen responsible for health, social affairs, and public order, and by commissions set up by the city council. Two remarkable aspects of the administration of drug-related affairs are a close cooperation between health authorities and the police, and an emphasis on Japanese-style neighborhood policing. The support and treatment services for drug users are run by private foundations that are fully financed by the government and the city. The extent and the variety of available services is impressive, ranging from consultation bureaus and daycare centers to intensive care units and a methadone dispensing program for 1 200 daily customers. The extensive system of municipal services is supplemented by voluntary aid mainly provided by churches and religious organizations. The Dutch way of dealing with the drug problem thus combines tolerance for drug use with a comprehensive network of services for drug users and a strict and carefully designed administration. Such an approach derives from the traditions of governance and political culture in Dutch society. These are crystallized in three character masks: those of the pragmatic and prudent merchant who is more concerned with practical problems than lofty ideals, the charitable and paternalistic priest, and the humble engineer who in his age-long fight against floods has learned that nature can be controlled but never fully tamed.

Superficially, the nature of German rule in Togo differed from that of the other German colonies. For example, right from the start, it was administered by Imperial officials. It thereby escaped some of the worst abuses of Chartered Company rule. Again because of the peculiar nature fo the country—it was very small, not particularly suitable for European settlement and much of its agricultural land was already under peasant cultivation, to which it was best suited—Togo escaped the large-scale expropriation of the subject peoples' land that was characteristic of German rule elsewhere.
