This study explores how employees’ flow experience at work emerges, is sustained, and continuously grows over time. Based on the job demand-resource model, we propose the intraday upward spiral of flow: Challenging demands and job resources activate employees’ flow experience, further encouraging them to seek more challenges and resources. Furthermore, drawing on the perseverative cognition theory and spill-crossover model, we propose the inter-day upward spiral of flow: The antecedents (or consequences) of flow can overflow from work to the family domain and result in employees’ positive rumination, thus promoting the next-day flow experience. Our diary study generated 1,208 data points from 142 employees over 10 working days. We found that in the morning, challenging demands and job resources positively affected the participants’ flow, further encouraging them to pursue more challenging demands and job resources in the afternoon and thus enter this state again. Moreover, the afternoon’s challenging demands and job resources promoted the respondents’ problem-solving pondering at night, which further increased their next-morning challenging demands, job resources, and, thus, their flow. Through this study, we expand the emerging literature on positive organizational behavior and provide information for practitioners on how to build and sustain employees’ peak states.

This article examines anti-mask protests in the United States in the context of the COVID-19 pandemic. Specifically, I look at the cultural (mis)appropriation of slogans by anti-mask protestors, such as “I can’t breathe” and “My body, my choice.” Noting that this is at first glance a bit of a puzzling phenomenon, I show that there is a relationship between the anti-mask protest, white Christian grievance politics, and the disintegration of the public sphere. Drawing on the work of Bonnie Honig, I argue that the anti-mask protests represent a mode of opting out of public engagement, hence opting out of the practice of using rational argumentation to explain why things ought to be a certain way, as well as listening to the reasons of others. Insofar as this has become a popular mode of engagement among a significant number of Americans, it needs to be understood in the language of foregoing responsibility for others in US pluralistic democracy. Indeed, further explication of the relationship between responsibility and freedom is absolutely necessary. I maintain that opting out is ethically untenable because of the nature of interdependence with others and the necessity of adhering to the rule of law. An ethic of reciprocity properly grounds an understanding of embodied freedom, resisting the extremes of grievance politics.

What is the gap between scholars’ expectations of media-sourced data and the realities those data actually represent? This letter elucidates the data generation process (DGP) that undergirds media-sourced data: journalistic reporting. It uses semi-structured interviews with 15 journalists to analyze how media actors decide what and how to report—in other words, the “why” of reporting specific events to the exclusion of others—as well as how the larger professional, economic, and political contexts in which journalists operate shape the material scholars treat as data. The letter thus centers “unreported realities”: the fact that media-derived data reflect reporters’ locations, identities, capacities, and outlet priorities, rather than providing a representative sample of ongoing events. In doing so, it reveals variations in the consistency and constancy of reporting that produce unacknowledged, difficult-to-identify biases in media-sourced data that are not directionally predictable.

There has been increasing interest in the effects of note taking in second language (L2) research. However, no meta-analysis has been conducted to examine the relationship between note taking and learning through exposure to L2 input. We retrieved 28 effect sizes from 21 studies (N = 1992) to explore the overall effects of note taking as well as to examine the extent to which the effectiveness of note taking is likely to vary as a function of a set of potential moderators (i.e., learner variables, treatment variables, note-taking features, learning target, and measurement type). Results revealed that note taking had a small to medium positive overall effect on learning through exposure to L2 input (g = 0.56, 95% CI: 0.24–0.88). Subsequent moderator analyses revealed that variability in the size of note-taking effects across studies was explained by learner variables (context, region, orthographic scripts, institutional level), treatment variables (mode of input, material type), note-taking features (note-taking behavior, number of note-taking sessions, provision and type of note-taking strategy instruction, total length of instruction, opportunity to review notes), learning target, and measurement type. Based on the obtained findings, teachers are recommended to incorporate note taking in L2 classrooms. Pedagogical suggestions and directions for future research are also provided.

We study spaces of continuous functions and sections with domain a paracompact Hausdorff k-space $X$ and range a nilpotent CW complex $Y$, with emphasis on localization at a set of primes. For $\mathop {\rm map}\nolimits _\phi (X,\,Y)$, the space of maps with prescribed restriction $\phi$ on a suitable subspace $A\subset X$, we construct a natural spectral sequence of groups that converges to $\pi _*(\mathop {\rm map}\nolimits _\phi (X,\,Y))$ and allows for detection of localization on the level of $E^2$. Our applications extend and unify the previously known results.

A dense Ecklonia radiata (Laminariales) kelp forest extending at least 35 km has been found between 45 and 60 m depth range within the mesophotic zone inside the iSimangaliso marine-protected area (MPA) at the iSimangaliso Wetland park World Heritage Site on the east coast of South Africa. This is the first visual confirmation of the occurrence of E. radiata beds in subtropical South Africa, in an area situated between the tropical and subtropical bioregions, in an area that spans the Natal and Delagoa bioregions of the south-western Indian Ocean, more than 350 km north of its previously documented South African range. The kelp was found to be present across the length of the MPA, but dense beds were present only in the southern Natal bioregion, with sparse occurrences observed elsewhere on soft-coral and sponge-dominated reefs in the upper mesophotic zone. The footage was collected in November 2020, May 2021 and November 2022 during remotely operated vehicle and drop camera surveys of the mesophotic zone inside the MPA. This discovery adds to the body of knowledge on the global distribution of Laminariales populations in deep tropical and subtropical settings and the diversity of habitats within South Africa's largest coastal MPA.

“Building Blocs” charts a global history of the last great crisis of globalization—the transwar decades from the 1880s through the 1940s—by centering strategic minerals needed to make steel. Little studied, but critically important, alloying minerals like tungsten and manganese were only needed in small amounts, but they were essential to the foundations of both national prosperity and security: steel and military production. Herein lay a fundamental problem: none of the industrial powers possessed adequate domestic deposits of these minerals, which were concentrated in remote locations such as central India, the Caucasus, southern China, Brazilian jungles, the Australian outback, and southern Africa. In a world in which steel was power, “Building Blocs” shows that resource anxieties motivated interwar quests for autarky and autonomy in the form of self-contained blocs. The scramble for strategic minerals escalated tensions and put rivals on the road to war, reshaping the forms and structures of geopolitical entities and international institutions throughout the transwar period.

The coronavirus disease 2019 (COVID-19) pandemic has provided a great lesson for the globe about the necessity and significance of pandemics-related preparedness in all settings. Public health emergency operation centers play critical roles in preparing for and responding to public health events and emergencies by coordinating and pooling resources. In this article, we aimed to share lessons learnt from the public health response to the louse-borne relapsing fever (LBRF) outbreak coordinated by the emergency operation center established to respond to the COVID-19 pandemic in Jimma, Ethiopia.

After the major waves of COVID-19 outbreaks in Ethiopia were over, Jimma University Medical Center (JUMC) reported clusters of louse-borne relapsing fever cases from Jimma Main Prison. Accordingly, Jimma Emergency Operation Center (JEOC) established for the COVID-19 pandemic was immediately alerted and effectively coordinated the overall response.

As a result, the outbreak was contained within the prison without spreading to the community and the outbreak ended within a shorter period compared to previous LBRF outbreaks in Ethiopia. This indicates the necessity of establishing and sustaining public health emergency operation centers to prepare for and combat potential future public health emergencies.

We investigate the groups of units of one-relator and special inverse monoids. These are inverse monoids which are defined by presentations, where all the defining relations are of the form $r=1$. We develop new approaches for finding presentations for the group of units of a special inverse monoid, and apply these methods to give conditions under which the group admits a presentation with the same number of defining relations as the monoid. In particular, our results give sufficient conditions for the group of units of a one-relator inverse monoid to be a one-relator group. When these conditions are satisfied, these results give inverse semigroup theoretic analogues of classical results of Adjan for one-relator monoids, and Makanin for special monoids. In contrast, we show that in general these classical results do not hold for one-relator and special inverse monoids. In particular, we show that there exists a one-relator special inverse monoid whose group of units is not a one-relator group (with respect to any generating set), and we show that there exists a finitely presented special inverse monoid whose group of units is not finitely presented.

A growing literature focuses on the role of political partisanship in shaping attitudes and behaviors during the COVID-19 pandemic in the United States. We provide a different perspective, by developing a theory of how partisanship interacts with another important factor that shapes how people think and behave in the context of the pandemic—local norms. Using a combination of survey data and a survey experiment, we demonstrate the importance of norms in shaping both support for social distancing and reported social-distancing behavior, particularly amongst independents and Republicans. We then confirm that perceptions of norms are indeed tied to what is actually happening around people—that their partisanship does not blind them to reality. Our analysis is the first to examine how partisanship and norms interact with each other and helps to explain why partisan differences matter more in some places than in others.

Let $K={\mathbb {Q}}(\theta )$ be an algebraic number field with $\theta $ satisfying a monic irreducible polynomial $f(x)$ of degree n over ${\mathbb {Q}}.$ The polynomial $f(x)$ is said to be monogenic if $\{1,\theta ,\ldots ,\theta ^{n-1}\}$ is an integral basis of K. Deciding whether or not a monic irreducible polynomial is monogenic is an important problem in algebraic number theory. In an attempt to answer this problem for a certain family of polynomials, Jones [‘A brief note on some infinite families of monogenic polynomials’, Bull. Aust. Math. Soc. 100 (2019), 239–244] conjectured that if $n\ge 3$, $1\le m\le n-1$, $\gcd (n,mB)=1$ and A is a prime number, then the polynomial $x^n+A (Bx+1)^m\in {\mathbb {Z}}[x]$ is monogenic if and only if $n^n+(-1)^{n+m}B^n(n-m)^{n-m}m^mA$ is square-free. We prove that this conjecture is true.

Record-sized specimens of the ornate eagle ray Aetomylaeus vespertilio and mangrove whipray Urogymnus granulatus were caught by single-day trawlers off Pamban Island in the Gulf of Mannar, Tamil Nadu, India during 2021 and 2022. All were landed at the Pamban Therkuvadi Fish Landing Centre (FLC). The largest ornate eagle ray was 384 cm disc width (DW) and weighed 530 kg, setting a new global record for the species, as the previous maximum size was reported to be 300 cm DW. This specimen was landed on 19 July 2021. Another large specimen of this species (360 cm DW and total weight of 453 kg) was caught and landed on 12 August 2022. The landed mangrove whipray was 153 cm DW and 150 kg total weight, larger than the previously reported maximum size of 141 cm DW. The morphometrics, stomach contents and reproductive state were studied. One of the eagle rays was a pregnant female with three full-term embryos in the uterus, while the whipray was a spent female. The main prey species in the stomach of eagle ray was big-eye scad Selar crumenophthalmus. The mangrove whipray had fed on a range of fish (pigface bream, goatfish, silverbellies, silverbiddies and lesser sardine) and octopus.

We give an adequate, concrete, categorical-based model for Lambda-${\mathcal S}$, which is a typed version of a linear-algebraic lambda calculus, extended with measurements. Lambda-${\mathcal S}$ is an extension to first-order lambda calculus unifying two approaches of non-cloning in quantum lambda-calculi: to forbid duplication of variables and to consider all lambda-terms as algebraic linear functions. The type system of Lambda-${\mathcal S}$ has a superposition constructor S such that a type A is considered as the base of a vector space, while SA is its span. Our model considers S as the composition of two functors in an adjunction relation between the category of sets and the category of vector spaces over $\mathbb C$. The right adjoint is a forgetful functor U, which is hidden in the language, and plays a central role in the computational reasoning.

This essay examines the intellectual history of the idea of judicial restraint, starting with the early debates among the US Constitution’s founding generation. In the late nineteenth century, law professor James Bradley Thayer championed the concept and passed it on to his students and others, including Oliver Wendell Holmes Jr., Learned Hand, Louis Brandeis, and Felix Frankfurter, who modified and applied it based on the jurisprudential preoccupations of a different era. In a masterful account, Brad Snyder examines Justice Frankfurter’s attempt to put the idea into practice. Although Frankfurter arguably made a mess of it, he passed the idea of judicial restraint on to Alexander Bickel and others. Today it remains a topic of much academic debate, while Supreme Court Justices occasionally give the idea lip service when it advances outcomes they desire.

I propose that the intellectual history of judicial restraint reflects the all-too-human inability to refrain from exercising power. The founders, focused on the need to mitigate the flaws of human nature in designing the executive and legislative branches, failed to sufficiently foresee how the same flaws would affect members of the judiciary. The failed idea of judicial restraint stands as the legacy of the founders’ mistake.
