Pricing is an essential element that significantly impacts the supply chain mechanisms. The primary objective of this study is to explore the transmission of producer-to-consumer prices in the Spanish fresh tomato industry. Employing the Threshold Vector Autoregressive model, and subsequently utilizing the Generalized Impulse Response Function, we investigated the nonlinear price adjustments that occur in response to positive and negative shocks affecting both tomato prices of consumers and producers. The findings show a clear pattern of distinct reactions between segments in response to shocks. Specifically, the speed and intensity of consumer price responses to producer price shocks appear to surpass those observed when producer prices respond to consumer price shocks. Furthermore, it is evident from the current research that the behavior of producers has evolved from earlier studies that utilized outdated information, suggesting a more competitive approach. The research identifies a new trend in producer behavior within the supply chain. By analyzing tomato price fluctuations, it advances current knowledge and provides essential market insights to support informed decision-making.
In recent years, there has been a sharp increase in the number of online fraud cases. However, research on crime geography has paid little attention to online crimes, especially to the influencing factors behind their spatial distributions. Online fraud is closely related to people’s daily internet use. The existing literature has explored the impact of internet use on online crimes based on small samples of individual interviews. There is a lack of large-scale studies from a community perspective. This study applies the routine activity theory to online activities to test the relationship between online fraud alert data and the usage durations of different types of mobile phone users’ applications (apps) for communities in ZG City. It builds negative binomial regression models for analyzing the impact of the usage of different types of apps on the spatial distribution of online fraud. The results reveal that the online fraud crime rate and the online time spent on a financial management app share the most similar spatial distribution. While financial management, online education, transportation, and search engine app usages have a significant positive association with online fraud, the use of a financial management app has the greatest impact. Additionally, time spent on social media, online shopping and entertainment, and mobile reading apps have a significant negative association with online fraud. As not all online activities lead to cybercrime, crime prevention efforts should target specific types of apps, such as financial management, online education, transportation, and search engines.
This article focuses on the challenges that uncertainty poses to countries in global and regional value chains. In this perspective, it focuses specifically on African countries and enriches the results with a comparative approach. Indeed, using a gravity model for 49 African countries and all their trading partners from 1990 to 2019, the paper proposes a comparative analysis of the effects of uncertainty on global trade in value chains and on trade in value chains within Africa. The robustness of the results shows that domestic uncertainty can drive the expansion of intra-African trade in value chains, while uncertainty in the partner country hinders the flourishing of trade relationships within a value chain.

L’histoire du football est autant écrite dans les grands stades des métropoles que dans ceux plus petits des villes moyennes ou des villages. Le bassin minier du nord de la France en offre un exemple tout à fait éclairant avec le stade de l’Étoile Sportive de Bully-les-Mines. Cette enceinte témoigne du dynamisme du football du Nord de la France dès la veille de la Grande Guerre et des aménagements et des œuvres sociales des Compagnies des Mines. Lieu autant de contrôle social que de réalisation de soi-même, le stade dont la tribune est achevée en 1927 est omnisport tout en devenant le terrain de l’ES Bully qui brille en Coupe de France. Aux heures de l’occupation allemande, le stade devient l’un des lieux de distraction en des temps difficiles. Il est aujourd’hui le théâtre du football amateur du dimanche.
The planetary boundaries framework defines a safe operating space for humanity. To date, these boundaries have mostly been investigated separately, and it is unclear whether breaching one boundary can lead to the transgression of another. By employing a dynamic global vegetation model, we systematically simulate the strength and direction of the effects of different transgression levels of the climate change boundary (using climate output from ten phase 6 of the Coupled Model Intercomparison Project models for CO _2 levels ranging from 350 ppm to 1000 ppm). We focus on climate change-induced shifts of Earth’s major forest biomes, the control variable for the land-system change boundary, both by the end of this century and, to account for the long-term legacy effect, by the end of the millennium. Our simulations show that while staying within the 350 ppm climate change boundary co-stabilizes the land-system change boundary, breaching it (>450 ppm) leads to critical transgression of the latter, with greater severity the higher the ppm level rises and the more time passes. Specifically, this involves a poleward treeline shift, boreal forest dieback (nearly completely within its current area under extreme climate scenarios), competitive expansion of temperate forest into today’s boreal zone, and a slight tropical forest extension. These interacting changes also affect other planetary boundaries (freshwater change and biosphere integrity) and provide feedback to the climate change boundary itself. Our quantitative process-based study highlights the need for interactions to be studied for a systemic operationalization of the planetary boundaries framework.
The Mediterranean identity is becoming an intriguing tool for city authorities willing to implement policies of urban regeneration all over the basin. More specifically, all around the Mediterranean coast, independently on the national and local features, many cities are branding their identity as a “Mediterranean one” to promote gentrification projects, attract investments, develop tourism and re-shape their cultural identity for the global scene.In our paper, we are going to investigate the main common characters of this Mediterranean branding process by comparing three cases of very different Mediterranean cities: Napoli, Marseille and Rijeka. These cities are peripherally located within their national territories and although part of quite diverse nation-building process, they are all targets of regeneration policies that exploit their maritime immaterial and material heritage, usually emphasized by “big events” (such as ECOC in Marseille 2013 and Rijeka 2020, or the America’s cup in Napoli). Thus, our aim is twofold: on one hand we shall point out the common ideological features of this regeneration-oriented Mediterranean narrative by focusing on and deconstructing the driving concept of local cosmopolitanism. On the other one, we will explore the practices of exclusion hidden behind this Mediterranean narrative by stressing the unspoken discard and removal of some undesired people, histories and heritage from the picture of regeneration. Our investigation is based on the quantitative and qualitative analysis of tourist masterplans, city sponsored cultural promotion materials and audio-visual advertisements of the city. Also, visual ethnography of the urban beaches, port-areas and waterfronts aimed at detecting and quantifying landmarks, signs and symbols of the Mediterranean-ess.
Introduction. A. N. Radishchev in his writings lays the foundations of a humanistic study of Russian society and an anthropological
understanding of economic orders. Most of the works were not published during his lifetime; the scientific publication of works and the study of
views, mainly of a social nature, was undertaken in the 1940s–1950s. The comments emphasized the radical worldview of the thinker, manifested
in the literary fi eld. In reality, the enlightener’s work is more multifaceted and covers philosophy, law, history, and economics. Three life periods
are distinguished, diff erent in subject matter, but consonant with moral ideas. Theoretical analysis. The fi rst period of writing is characterized
by works of social philosophy, fi ction and offi cial notes of a legal and economic nature, in which Radishchev’s ambivalent attitude to power, awmaking and moral values is revealed. The probable coincidence of the enlightener’s views with his European contemporaries (Locke, Diderot,
A. Smith, Blackstone) and Russian philosophers (Tatishchev, Storkh) is revealed. Parallels with the works of I. Kant and the categorical apparatus
of modern economic anthropology are determined. Empirical analysis. The views of Radishchev and Catherine II are interpreted in a comparative
way. It is shown that there are no direct invectives in the “Journey from St. Petersburg to Moscow” against the Empress. The works on legislation
in the third period of creativity are an adjusted continuation of the works of the fi rst period. The most complete economic and anthropological
theme is presented in the essay “On Chinese Bargaining”, which implicitly rejects the principles of the government’s economic policy, which
does not take into account the spatial identity of Russia, its civilizational mission and the potential of free enterprise. Results. The writings
of A. N. Radishchev anticipate the fi eld of research of modern economic anthropology: the importance of refl ection in human behavior, its noumenal and phenomenal representation, historical construction of ways of action and thought, performative thinking, hierarchy and fragmentation
of power, structuration of economic (market) relations are taken into consideration. The key concepts are collective faith, feelings and habits,
inclinations and individual diff erences, good-action, objective and subjective interests, reasonableness and rationality in historical refraction.
The problems of conciliarity, will, moral imperatives, acquisition of systematic knowledge, necessity of laws, human rights are highlighted as the
most important from the position of the enlightener.

Os jogos digitais incorporaram-se nas vivências de lazer de crianças e jovens. São importantes mediadores da cultura contemporânea e apresentam indícios de potencial educativo nas experiências lúdicas que produzem. Nesse sentido, o objetivo do estudo foi compreender por quais vias ocorre a educação para os games e identificar expressões de aprendizagem por meio da vivência dos jogos digitais. Aplicamos um questionário com 21 alunos e 14 alunas de 6° ano do ensino fundamental, com faixa etária entre 10 e 14 anos. Identificamos a mediação familiar e domiciliar no princípio da educação para os jogos digitais, bem como a presença dos círculos de amizades e das tecnologias nesse processo. Neste ponto chamamos atenção para a ausência da escola, da Educação Física e, principalmente, do Estado como instituições e ambiências mediadoras da formação cultural infanto-juvenil para, com e sobre o universo lúdico digital.
The question of whether each building of housing estate has equal access to nearby social service resources (e.g., public transportation service, catering, entertainment, etc.) is a major concern of citizens. This paper takes Wuhan as a case to explore the equality in social service resource sharing of the housing estate at a microscopic level by analyzing the accessibility of each building under different travel patterns. To estimate the accessibility of each building, we developed a novel model with multi-travel modes and residential suitability evaluation of residents. The specific values of the parameters involved in the proposed model were extracted from the multi-source spatial data such as social media data, census data, point of interest, and road network data. These data were acquired from multiple platforms, e.g., Gaode map, OSM (OpenStreetMap), and GeoQ. We chose three types of districts in the city of Wuhan, including the old central district, new central district, and suburban district. We applied the proposed model to assess the accessibility of communities in these districts. Based on the results, we further analyzed whether and to what extent the distribution of each building in urban communities is equitable for social service resource sharing in China.
