Greenways and Ecological Networks: Concepts, Differences, Similarities

In recent decades green infrastructure (GI) frameworks have been widely used for developing theoretical and practical models of sustainable land reorganization. Although there is still much confusion regarding various aspects of green infrastructure, since many differing perspectives have generated different definitions that emphasise the complexity of the green infrastructure concept, it is possible to find important differences and common points

Average Bateman--Horn for Kummer polynomials

For any $r \in \mathbb{N}$ and almost all $k \in \mathbb{N}$ smaller than $x^r$, we show that the polynomial $f(n) = n^r + k$ takes the expected number of prime values as $n$ ranges from 1 to $x$. As a consequence, we deduce statements concerning variants of the Hasse principle and of the integral Hasse principle for certain open varieties defined by equations of the form $N_{K/\mathbb{Q}}(\mathbf{z}) = t^r +k \neq 0$ where $K/\mathbb{Q}$ is a quadratic extension. A key ingredient in our proof is a new large sieve inequality for Dirichlet characters of exact order $r$.Comment: V2: Minor correction

Law and Language: An Interdisciplinary Perspective

In a famous passage of his 1919 essay The Uncanny, in an attempt to elucidate the meaning of the German word “Das Unheimliche”, Sigmund Freud concluded that any effort would have be in the end vain for the simple reason that «we ourselves speak a language that is foreign». With this paradoxical statement, Freud disclosed the radical alterity which exists between human beings and language. Even if usually we think about linguistic expressions as the cultural device which represents par excellence the real condition of human life, language could prove to be something elusive and mysterious. Our legal tradition has always grounded its cultural and political existence upon language: since the times of the German historical school, language, law and society were considered strictly intertwined. Anyway, with the coming of postmodernism and globalization, as well as of complex political frameworks, this simplistic narrative has been progressively thrown into crisis. Following authors like Saussure, Benveniste, Foucault and Appadurai, as well as the precious insights provided by the Legal Realist movement, this paper aims to investigate the conflicting connection which nowadays takes place in legal and economic discourses. If it is true that traditionally law and language appear so strictly intertwined, every deconstruction of legal words casts its dark shadows upon our material and concrete existence: the erosion of legal language necessarily leads to a certain loss of fundamental rights, that is, of justice. In the age of “surmodernity” – as the French anthropologist Marc Augè called it – language becomes then a testing ground for verifying the evolution of contemporary sovereignty.In a famous passage of his 1919 essay The Uncanny, in an attempt to elucidate the meaning of the German word “Das Unheimliche”, Sigmund Freud concluded that any effort would have be in the end vain for the simple reason that «we ourselves speak a language that is foreign».

Food Insecurity—How does it Affect the U.S.?

In 2016, 12.3% of all US households (15.6 million households) experienced food insecurity sometime during the year. Of these households 7.4% ( 9.4 million households) experienced low food security and 4.9%( 6.1 million households) experienced very low food security (Hoblen & Marshall, 2019). Not only is food insecurity a significant problem in the United States, but it is also impacted by many factors such as gender, racial and ethnic groups, cultures and socioeconomic status. This problem in the United States was researched to continue finding information of how to eliminate inequalities that exist amongst diverse populations of this country, due to food insecurity. Data was found from looking at the work of various researchers in published peer reviewed articles that further explained the statistical impact that food insecurity has on individuals and families. It was concluded that those who identify with groups such as Black, Hispanic, Mexican or Puerto Rican as well who live in poverty stricken or low-income neighborhoods experience the greatest food insecurity and have the most barriers in achieving healthy food and a healthy lifestyle

Degrees of closed points on diagonal-full hypersurfaces

Let $k$ be any field. Let $X \subset \mathbb{P}_k^N$ be a diagonal-full degree $d$ hypersurface, where $d$ is an odd prime. We prove that if $X(K) \neq \emptyset$ for some extension $K/k$ with $n:=[K:k]$ prime and $gcd(n,d)=1$, then $X(L) \neq \emptyset$ for some extension $L/k$ with $gcd([L:k], nd)=1$ and $[L:k] \leq nd-n-d$. Moreover, if a $K$-solution is known explicitly, then we can compute $L/k$ explicitly as well. When $n$ or $d$ is not prime, we can still say something about the possible values of $[L:k]$. As an example, we improve upon a theorem by Coray on smooth cubic surfaces $X \subset \mathbb{P}^3_k$, in the case when $X$ is diagonal-full, by showing that if $X(K) \neq \emptyset$ for some extension $K/k$ with $gcd([K:k], 3)=1$, then $X(L) \neq \emptyset$ for some $L/k$ with $[L:k] \in \{1, 10\}$.Comment: Comments welcome
