Despite societal perceptions of older adults as vulnerable, literature on resilience suggests that exposure to adversity and resources gained with life experience contribute to adaptation. One way to explore the nature of resilience is to document assets supporting adaptation. Interviews were conducted with older adults living in Canada at two time points during the COVID-19 pandemic, September 2020–May 2021 (T1) and January–August 2022 (T2). Reflexive thematic analysis was completed to report on what older adults identified as assets and how they understood the value of those assets for resilience. Participants indicated that the potential value of their contributions went largely untapped at the level of the community but supported individual and household adaptation. In line with calls for an all-of-society approach to reduce disaster risk and support resilience, creating a culture of inclusivity that recognizes the potential contributions of older adults should be paired with opportunities for action.

We investigate neighbourhood sizes in the enhanced power graph (also known as the cyclic graph) associated with a finite group. In particular, we characterise finite p-groups with the smallest maximum size for neighbourhoods of a nontrivial element in its enhanced power graph.

The impact of disasters on the health and wellbeing of children is well documented, with children identified as bellwethers of community recovery. It has also been demonstrated that building community-wide resilience benefits from being approached through a child-centric model of community participation. While much of this work has been focused on the USA, there is a need to develop models to adapt these approaches in international environments. Small Island Developing States (SIDS) are particularly at risk for disaster events. SIDS tend to have less diverse economies and a high dependence on climate-sensitive sectors that are vulnerable to disasters. The National Center for Disaster Preparedness at Columbia University along with Save the Children created The Resilient Children, Resilient Communities Initiative to build child-focused resilience within communities. The Initiative, which has already been applied to sites in the USA, is being adapted for the context of Dominica. The Initiative focuses on child-serving institutions and uses a Community Preparedness Index to quantify the current inventory of policies and practices related to children. The Initiative aims to implement strategies to improve the ability of the community to meet the needs of children in a disaster. This paper explores the application of these concepts surrounding the Initiative.

Panulirus stimpsoni is restricted to southern China, Vietnam, and Japan but has been rarely reported in tropical Gulf of Thailand. In Malaysia, only six species were previously reported. This study (1) reports the seventh Malaysian species – a new record of P. stimpsoni with morphological and genetic data; (2) establishes a checklist of Malaysian Panulirus species. Surveys from 2021 to 2022 sampled lobsters across Malaysia by SCUBA or from fishermen. Seven species were identified and a modified key of Malaysian species was constructed. The COI gene was used for genetic identification and phylogenetic tree reconstruction with maximum likelihood (ML). The best model was GTR + I + G. The ML tree comprised Clades I and II with sequences clustering by species and strong support. Most Peninsular Malaysian lobsters were P. polyphagus while P. versicolor dominated Sabah. Information on P. stimpsoni's full fishery potential, distribution, ecology, and biology is limited. Further research is needed to ensure conservation and management as data are only available for six previously reported species. Further studies are required to discover sustainable use approaches for all Panulirus species, particularly P. stimpsoni, given limited ecological understanding.

Insects experience variable temperature conditions in their natural environment, making constant temperature conditions in studies unrealistic. To address this, we investigated the effects of repeated short-term heat stress (STH) and short-term cold stress (STC) conditions on the pre-oviposition, oviposition, and post-oviposition periods, as well as on fecundity and egg viability of the parthenium beetle, Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae). We found that pre-oviposition periods were shortest under STH conditions and at the optimal temperature and longest under STC conditions. Conversely, oviposition and post-oviposition periods were longest at the optimal temperature. Oviposition periods were shortest under STH, whereas post-oviposition periods were shortest under both STH and STC conditions. Age-specific fecundity trends were triangular, and egg-viability trends were plateau-shaped at all temperatures. Females subjected to STH conditions experienced the highest oviposition peaks early in their adult life. Conversely, lifetime fecundity and longevity were highest at the optimal temperature, whereas egg viability was maximal under STH conditions. Regardless of the temperature they were maintained at, middle-aged females exhibited the highest fecundity and egg viability. Based on these results, despite reducing overall fecundity and longevity, STH conditions enhanced daily oviposition in females, with the peak occurring early in adult life. Additionally, both STH and STC conditions increased percentage egg viability in parthenium beetles.

In Oliveira, Schlomiuk, Travaglini, and Valls, Geometry, integrability and bifurcation diagrams of a family of quadratic differential systems as application of Darboux theory of integrability, Electron. J. Qual. Theory Differ. Equ. 45(2021), 1–90, the authors investigate about the integrability of the family QSH (the whole class of non-degenerate planar quadratic systems possessing at least one invariant hyperbola). However, some very difficult cases are left open in Oliveira, Schlomiuk, Travaglini, and Valls, Geometry, integrability and bifurcation diagrams of a family of quadratic differential systems as application of Darboux theory of integrability, Electron. J. Qual. Theory Differ. Equ. 45(2021), 1–90, and the main aim of this article is to study the Liouvillian integrability some of the systems that were left behind in Oliveira, Schlomiuk, Travaglini, and Valls, Geometry, integrability and bifurcation diagrams of a family of quadratic differential systems as application of Darboux theory of integrability, Electron. J. Qual. Theory Differ. Equ. 45(2021), 1–90.

We improve known estimates for the number of points of bounded height in semigroup orbits of polarized dynamical systems. In particular, we give exact asymptotics for generic semigroups acting on the projective line. The main new ingredient is the Wiener-Ikehara Tauberian theorem, which we use to count functions in semigroups of bounded degree.

This paper contains a method to prove the existence of smooth curves in positive characteristic whose Jacobians have unusual Newton polygons. Using this method, I give a new proof that there exist supersingular curves of genus $4$ in every prime characteristic. More generally, the main result of the paper is that, for every $g \geq 4$ and prime p, every Newton polygon whose p-rank is at least $g-4$ occurs for a smooth curve of genus g in characteristic p. In addition, this method resolves some cases of Oort’s conjecture about Newton polygons of curves.

Prior research on status has focused primarily on the cognitive perspective, exploring the effects of status and offering a limited understanding of the impact of positive status change and its emotional mechanisms. This study draws upon the two-facet model of pride to examine how positive status change influences the behaviors of new status holders. Specifically, we propose that when status differentiation is low, positive status change enhances new status holders' prosocial behavior through their authentic pride, while in cases of high status differentiation, it increases their self-interested behavior through their hubristic pride. To test our hypotheses, we conducted a series of studies, including a laboratory experiment, a scenario experiment, and a time-lagged multilevel and multisource field study. Our multilevel analyses of the data provided strong support for our hypotheses. Our findings shed light on when and why positive status change triggers different behaviors among new status holders, offering important insights into the emotional mechanisms that underlie the effects of status change.

This article examines the role of state-owned firms in economic growth. While some scholars denigrate state firms, most analysts of East Asian development have noted their importance. To date, however, little work has been done on how state firms operate and how they have actually contributed to industrial development and economic growth. Looking closely at postwar Taiwan as a newly industrializing country and the case of Taiwan Machinery Manufacturing Corporation (TMMC), this article argues that state enterprises resolved coordination failures and provided manufacturing capacity to infant industries. Drawing on company archives and state records, I argue that TMMC helped drive growth through the provision of manufacturing machinery, equipment, parts, repairs, and upgrading. By supplying firms with the necessary technology and materials to modernize production and be competitive on the global market, I show how TMMC helped facilitate Taiwan’s economic miracle.

As I read Zhang and Chen's (2024) perspective paper, I was impressed with the authors' flexibility moving into the medical field and the impact of their research. Moreover, I agreed wholeheartedly with their call to learn by working across fields and with their assessment of how differently management and healthcare scholarship is created, disseminated, and used. Yet I was quite stumped by the editor's request that I suggest some ‘urgent and pressing’ issues that might help management scholars achieve the kind of practical relevance of medical researchers.

For a prime p and a rational elliptic curve $E_{/\mathbb {Q}}$, set $K=\mathbb {Q}(E[p])$ to denote the torsion field generated by $E[p]:=\operatorname {ker}\{E\xrightarrow {p} E\}$. The class group $\operatorname {Cl}_K$ is a module over $\operatorname {Gal}(K/\mathbb {Q})$. Given a fixed odd prime number p, we study the average nonvanishing of certain Galois stable quotients of the mod-p class group $\operatorname {Cl}_K/p\operatorname {Cl}_K$. Here, E varies over all rational elliptic curves, ordered according to height. Our results are conditional, since we assume that the p-primary part of the Tate–Shafarevich group is finite. Furthermore, we assume predictions made by Delaunay for the statistical variation of the p-primary parts of Tate–Shafarevich groups. We also prove results in the case when the elliptic curve $E_{/\mathbb {Q}}$ is fixed and the prime p is allowed to vary.
