We present findings from historical microdata that suggest former rural elites effectively preserved their socio-economic advantages into the early People's Republic of China (PRC, circa 1949–1965) by exploiting urban–rural differences in government policies. In particular, former rural elites were three to four times more likely than poor peasants to move to a nearby town, and this urbanization was highly associated with socio-economic privileges in a rapidly developing economy, including both income and educational opportunities. We also find evidence that after 1949, former rural elites who did urbanize were more likely than their poor peasant counterparts to find industrial jobs.

Typically, weed density is used to predict weed-induced yield loss, as it is easy and quick to quantify, even though it does not account for weed size and time of emergence relative to the crop. Weed-crop leaf area relations, while more difficult to measure, inherently account for differences in plant size, representing weed-crop interference more accurately than weed density alone. Unmanned aerial systems (UAS) may allow for efficient quantification of weed and crop leaf cover over a large scale. It was hypothesized that UAS imagery could be used to predict maize yield loss based on weed-crop leaf cover ratios. A yield loss model for maize (Zea mays L.) was evaluated for accuracy using 15- and 30-m altitude aerial RGB and four-band multispectral imagery collected at four North Carolina locations. The model consistently over and underpredicted yield loss when observed yield loss was less than and greater than 3000 kg ha-1, respectively. Altitude and sensor type did not influence the accuracy of the prediction. A correction for the differences between predicted and observed yield loss was incorporated into the linear model to improve overall precision. The correction resulted in r2 increasing from 0.17 to 0.97 and a reduction in RMSE from 705 kg ha-1 to 219 kg ha-1. The results indicated that UAS images can be used to develop predictive models for weed-induced yield loss prior to canopy closure, making it possible for growers to plan production and financial decisions before the end of the growing season.

In this paper, a large, compact array antenna that can be expanded in the 2-D plane is proposed for near-field radio frequency identification applications. By the introduction of the fractal structure and corner joint method, the array is easy to expand in the 2-D plane. An antenna element can be divided into a dozen or so loops, and traveling wave distribution makes sure that every loop is excited in a time period. So that a strong and uniform magnetic field could be generated in a large area. As a proof of concept, array antennas with $1 \times 8$, $2 \times 4$, and $3 \times 3$ elements are designed, fabricated, and measured. The measured bandwidth of the antennas covers the entire Chinese standard. Reading distances of the proposed large array antennas achieved up to 57 mm. Results show that the proposed antenna could realize flexibility and extendibility in a large area with stable and uniform magnetic field distribution.

This special Themed Collection of The Economic and Labour Relations Review examines the ‘Economics of Occupational Health and Safety’ (OHS). The economics of OHS looks at how economic structures and incentives, including labour markets and production processes, influence the health and wellbeing of workers and the communities where they live. It is a large and diverse subject that has been viewed from multiple different lenses. This thematic issue can only touch on some of these but will remind readers how economic incentives and industrial competitive pressures affect OHS. This editorial will take the form of an article which explores some of these intersections and places them in a wider context. To do this, the economics of OHS will not only be examined in terms of economic welfare and microeconomics at the industry and workplace level, but also from an historical perspective, as well as the intersection of these levels, thus providing a useful framework to shape research and discussion.

Let G be a linear real reductive Lie group. Orbital integrals define traces on the group algebra of G. We introduce a construction of higher orbital integrals in the direction of higher cyclic cocycles on the Harish-Chandra Schwartz algebra of G. We analyze these higher orbital integrals via Fourier transform by expressing them as integrals on the tempered dual of G. We obtain explicit formulas for the pairing between the higher orbital integrals and the K-theory of the reduced group $C^{*}$-algebra, and we discuss their application to K-theory.

Based on the case report of Nathan Goldstein et al., “But I have a pacer…there is no point in engaging in hypothetical scenarios”: A Non-imminently Dying Patient’s Request for Pacemaker Deactivation, it is reasonable to conclude that it was, all-things-considered, ethically appropriate to grant the patient’s request to deactivate her pacemaker. Philosophically, and as a clinical ethicist, I support the team’s decision to honor the patient’s request for pacemaker deactivation. However, it is worth exploring a bit further whether the distress on the part of the outside hospital’s ethics committee and providers—who declined to honor the patient’s request for pacemaker deactivation—may actually track something of moral significance. In this commentary, I argue that there are reasonable grounds for holding that deactivation of a ‘biofixture’ such as a pacemaker may be more analogous in moral terms to medical aid in dying than it is to standard cases of withdrawal of life support at the end of a patient’s life.

MagNetUS is a network of scientists and research groups that coordinates and advocates for fundamental magnetized plasma research in the USA. Its primary goal is to bring together a broad community of researchers and the experimental and numerical tools they use in order to facilitate the sharing of ideas, resources and common tasks. Discussed here are the motivation and goals for this network and details of its formation, history and structure. An overview of associated experimental facilities and numerical projects is provided, along with examples of scientific topics investigated therein. Finally, a vision for the future of the organization is given.

Nahdlatul Ulama (NU), the world’s largest Islamic organisation, is renowned for fostering tolerance in Indonesia. However, recent studies have revealed that the degrees of tolerance NU displays are inconsistent, throwing the organisation’s reputation for acceptance into question. By adopting critical juncture and case study analyses, this article finds that tolerance within NU is dynamic for three reasons. First, it evolves depending on the social-political context of the time. Second, NU upholds tolerance within specific limits, extending it to those who do not contradict the Islamic values it upholds and who do not pose a threat to the unitary state of the Republic of Indonesia (NKRI). Third, the commitment to tolerance by NU’s membership, the nahdliyin, varies and does not always align with NU’s principles.

Migrant residential concentration areas have been a significant focus for research, but academic attention has primarily centered on their effects rather than how they form. There is some research considering the discrete factors of such areas’ emergence, but these factors are rarely fused into a comprehensive explanation with a description of specific mechanisms in operation. Even less is known about the formation of migrant residential concentration areas in postsocialist cities. The few studies in existence leave the impression that such areas emerge around bazaars by default. In this article, based on a multicase study (N = 37) conducted in the 15 largest Russian cities, we argue that although there is a pattern of migrant residential concentration areas’ emergence in postsocialist cities, this process takes place only in the presence of a combination of seven factors. The article presents these factors and describes an ideal type of a migrant residential concentration area in a Russian city and mechanisms of its emergence. The article concludes with the comparison of the postsocialist pattern with other types of migrant residential concentration and hypothesizing on how the Russian case differs from the other postsocialist cases in Central and Eastern Europe.

Consider a simple argument that worshipping God is wrong. This world is not a nice place. Not only do humans persecute and inflict other evils on each other, but millions of people suffer and die every year from preventable poverty-related causes, and it seems that few, if any, deserve their plights. It is unclear that we should want to be associated with, never mind worship, a being with the capacity to make the world a much better place but whose beneficence (or knowledge) permits things to go on in the ways that they do. At first blush, contempt is a more fitting response to God than worship. But, assuming God exists, perhaps we have reason to accept, if not worship, him in any case. Humans are comparably limited. We do evil unto each other, and, insofar as millions of deaths are preventable, our failure to prevent them is a failure of humans as well as of God. If we could (and should) have saved many lives and have not, our moral failings present us with our own, human, problem of evil and suffering. So, if we should reject God because so many people suffer, then we should reject ourselves when we could avoid evil and help others too. However, this article argues that we have practical, moral, and epistemic reasons to accept rather than reject ourselves, and similarly we have reasons to accept God. And if we have reason to accept God, then we have some reason to worship God. Worship is a way of acknowledging our own limitations and can help us survive, flourish, and help others in the face of the problems of human evil and suffering.

This study on distribution of Ophiothrix savignyi was carried out from 2017 to 2022 in the Iranian waters of the Persian Gulf. Nineteen locations were sampled from coastal waters, including 16 newly reported areas. O. savignyi was epizoic, associated mostly with sponges, sea urchins, and soft corals. This survey shows O. savignyi as the most common and widespread brittle star in the northern and eastern Persian Gulf. In this study, O. savignyi, has been described again from the Persian Gulf.

The terminology of “lives not worth living,” “worthwhile lives,” and “unworthwhile lives,” used by John Harris and many others, has become an accepted linguistic convention in bioethical discussions. These terms are used to distinguish lives of overwhelming negative experience from lives that are or are expected to be of overall positive value. As such, this terminology seems helpful in discussions around resource allocation, end-of-life decision making and questions of when it might be acceptable (and unacceptable) to reproduce. This paper argues that there is, however, a problematic ambiguity inherent in these general terms that is particularly evident when it comes to discussing reproductive choices. It is suggested that in this context, this ambiguity can conceal authoritarian eugenic motivations that are difficult to justify and that many using these terms would not adhere to. As a result, it is argued that we should replace these terms with the terms “intrinsically valuable” and “intrinsically harmful.” This would make it more explicit what exactly is meant and would allow these matters to be debated with greater clarity.

This study examines to what extent phonetic reduction in different accents affects intelligibility for non-native (L2) listeners, and whether similar reduction processes in listeners’ first language (L1) facilitate the recognition and processing of reduced word forms in the target language. In two experiments, 80 Dutch-speaking and 80 Spanish-speaking learners of English were presented with unreduced and reduced pronunciation variants in native and non-native English speech. Results showed that unreduced words are recognized more accurately and more quickly than reduced words, regardless of whether these variants occur in non-regionally, regionally or non-native accented speech. No differential effect of phonetic reduction on intelligibility and spoken word recognition was observed between Dutch-speaking and Spanish-speaking participants, despite the absence of strong vowel reduction in Spanish. These findings suggest that similar speech processes in listeners’ L1 and L2 do not invariably lead to an intelligibility benefit or a cross-linguistic facilitation effect in lexical access.

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease that affects the joints. Treatments are symptomatic and can induce side effects in some patients. In this sense and based on previous studies, our aim was to investigate the ex vivo immunoregulatory effect of the laminated layer (LL) during rheumatoid arthritis. LL is the outside layer of parasitic cyst of the helminth Echinococcus granulosus.

Our main objective was to study the effect of LL on nitric oxide (NO) and cytokines production, matrix metalloproteinases (MMPs) activities, inducible NO synthase (iNOS) and nuclear factor κappa B (NF-κB) expression. In this context, cultures of peripheral blood mononuclear cells (PBMC) from Algerian RA patients in active (ARA) and inactive (IRA) stage of the disease were stimulated with LL extract (50, 100, 150μg/mL). However, PBMC from ARA patients were stimulated with methotrexate (MTX; 0.5μg/mL) and biological disease modifying anti-rheumatic drugs (bDMARDs): anti-TNFα (10μg/mL), anti-IL6 (10μg/mL), anti-CD20 (10μg/mL), alone or combined with LL (50μg/mL).

Our results showed that LL reduced NO, TNF-α, and IL-17A production, MMP9/2 activities, and iNOS/NF-κB expression in PBMC from ARA patients. Concomitantly, LL increases IL-10 and TGF-β1 production in the same cultures. Interestingly, the decrease in NO production induced by bDMARDs was greater in association with LL.

Collectively, our findings indicate a strong immunoregulatory effect of LL on NO, MMPs, and cytokines. LL probably acts through the NF-κB pathway. The development of biodrugs derived from LL of E. granulosus could be a potential candidate to modulate inflammation during RA.
