The illegal theft of old trees threatens China’s ecological and cultural heritage. Despite legal protections, their high-value timber has persistently fuelled illicit trade driven by economic incentives and weak enforcement in remote areas, endangering biodiversity and cultural traditions. This Comment article proposes comprehensive and alternative approaches to combat the illegal theft of old trees by advocating for a strengthened legal framework, enhanced monitoring systems and increased support for local authorities. It highlights the importance of public awareness and community engagement in conservation efforts to address the ingrained economic drivers of this illegal trade.

This article investigates the observation that the object of obligatorily transitive verbs in Jordanian Arabic cannot drop in VSO clauses but can in SVO clauses as long as its referent is already mentioned in the previous discourse of an accompanying utterance. When object drop takes place, the subject of the accompanying clause should be a [+definite] or [+specific] element. This article provides an account of this generalization, based on the topic nature of the subject and the object, their structural positions in the high and low peripheries and the effect of relativized minimality in ruling out movement of one over the other.

This article explores the utility of content-embedded working memory capacity (WMC) tasks for advancing second language (L2) research. While both complex span and content-embedded tasks implement a dual-task paradigm that requires processing and maintenance of information, they differ in that the former demand maintenance of extraneous memory elements during processing, while the latter demand processing and maintenance of the same elements. Since manipulating information stored in working memory is critical for L2 processing and development, particularly in intentional learning contexts, content-embedded tasks may serve as strong predictors of several linguistic outcomes. We report preliminary evidence suggesting that both content-embedded tasks (available in IRIS [https://www.iris-database.org/details/iv6nR-HD9NQ]) and complex span tasks can be significant predictors of explicit L2 aptitude and L2 reading comprehension, but that content-embedded tasks can show advantages over complex span tasks in some instances. We discuss methodological implications for the measurement of WMC in L2 research.

Let X be the sum of a diffusion process and a Lévy jump process, and for any integer $n\ge 1$ let $\phi_n$ be a function defined on $\mathbb{R}^2$ and taking values in $\mathbb{R}$, with adequate properties. We study the convergence of functionals of the type

\begin{align*} \Delta_n\sum_{i=1}^{[t/\Delta_n]} \phi_n\!\left(\alpha_n\left[\frac{X_{(i-1)\Delta_n}}{\alpha_n}\right], \:\frac{\alpha_n}{\sqrt{\Delta_n}}\left(\left[\frac{X_{i\Delta_n}}{\alpha_n}\right]-\left[\frac{X_{(i-1)\Delta_n}}{\alpha_n}\right]\right)\right),\end{align*}

In this article, we describe meromorphic solutions of certain partial differential equations, which are originated from the algebraic equation $P(f,g)=0$, where P is a polynomial on $\mathbb {C}^2$. As an application, with the theorem of Coman–Poletsky, we give a proof of the classic theorem: Every meromorphic solution $u(s)$ on $\mathbb {C}$ of $P(u,u')=0$ belongs to W, which is the class of meromorphic functions on $\mathbb {C}$ that consists of elliptic functions, rational functions and functions of the form $R(e^{a s})$, where R is rational and $a\in \mathbb {C}$. In addition, we consider the factorization of meromorphic solutions on $\mathbb {C}^n$ of some well-known PDEs, such as Inviscid Burgers’ equation, Riccati equation, Malmquist–Yosida equation, PDEs of Fermat type.

In this study, we introduce multiple zeta functions with structures similar to those of symmetric functions such as the Schur P-, Schur Q-, symplectic and orthogonal functions in representation theory. Their basic properties, such as the domain of absolute convergence, are first considered. Then, by restricting ourselves to the truncated multiple zeta functions, we derive the Pfaffian expression of the Schur Q-multiple zeta functions, the sum formula for Schur P- and Schur Q-multiple zeta functions, the determinant expressions of symplectic and orthogonal Schur multiple zeta functions by making an assumption on variables. Finally, we generalize those to the quasi-symmetric functions.

The aim of this article is to analyse the Italian Nuova Destra. The first part examines the birth of the Nuova Destra within the current of the Movimento Sociale Italiano (MSI), referring particularly to Pino Rauti, a founder and leader. Following the experience of the magazine La Voce della Fogna and the Hobbit Camps, the first publishing initiatives of the Nuova Destra – Diorama letterario and Elementi, influenced by Alain de Benoist and the French Nouvelle Droite – were established. The second part analyses the path of the Nuova Destra as an autonomous cultural current. After Marco Tarchi’s expulsion from the MSI in 1981, the Nuova Destra launched an aggressive publishing strategy that failed to make the necessary organisational leap and came to an end around 1994. Nevertheless, the Nuova Destra has created a recognisable current, culturally eclectic and capable of ranging over different fields of knowledge with ‘metapolitics’ and ‘right-wing Gramscism’.

We prove that there exists a left-c.e. Polish space not homeomorphic to any right-c.e. space. Combined with some other recent works (to be cited), this finishes the task of comparing all classical notions of effective presentability of Polish spaces that frequently occur in the literature up to homeomorphism.

We employ our techniques to provide a new, relatively straightforward construction of a computable Polish space K not homeomorphic to any computably compact space. We also show that the Banach space $C(K;\mathbb {R})$ has a computable Banach copy; this gives a negative answer to a question raised by McNicholl.

We also give an example of a space that has both a left-c.e. and a right-c.e. presentation, yet it is not homeomorphic to any computable Polish space. In addition, we provide an example of a $\Delta ^0_2$ Polish space that lacks both a left-c.e. and a right-c.e. copy, up to homeomorphism.

This paper answers the question of how, according to Hegel, we can do philosophy of right. The first part of the paper deals with a critical dimension of Hegel’s understanding of the method of the philosophy of right. In the second part, it is shown that in the philosophy of right we consciously look at the present as forming a comprehensive context, as something that is resistant to mere thought and as something that is temporal. According to Hegel, what we consider in this way is concrete.
