Historians of the Cold War and the nuclear age have largely overlooked the existence of tabletop role-playing games (TTRPGs), while films, comics, novels, and television programmes that tackled the challenging imaginary, yet all-too-possible, wastes of a post-nuclear landscape have been abundantly analysed. As cultural products and tools through which to imagine other worlds, TTRPGs offer powerful insights into how, where, and why certain groups thought about the spectre of the nuclear age and how they dealt with this threat by gaming within make-believe postapocalyptic worlds. This article draws together several threads in its analysis of the American-designed and -produced Twilight: 2000 TTRPG’s historical significance. Through analysing Twilight: 2000 as a case study of how a TTRPG functions as a specific nuclear-cultural object in its own right, the article also locates this game as a part of a wider-reaching dystopian fantasy rooted in the massive everyday reality of atomic annihilation. Likewise, the game, its mechanics, setting, and artwork are analysed here as part of a distinctive Cold War culture that permitted participants to derive pleasure and affirmation from fictional “adventures” in the postapocalyptic environment.

Haritalodes derogata (Fabricius) (Lepidoptera: Crambidae), commonly known as the cotton leaf roller, is an important polyphagous pest that causes damage to various agricultural and forest plants, especially those of the Malvaceae family, but also to crops such as cotton, cashew, bamboo, oats, and jute. While microbial control agents are known for their efficacy and environmental friendliness, there are few studies demonstrating their effect on H. derogata. The aim of this study was to evaluate the bioefficacy of microbial agents from different pathogen groups against this pest. To this end, we investigated the insecticidal potential of fifteen indigenous microbial isolates from our entomopathogen collection. These included five Bacillus thuringiensis strains (Bn1, MnD, Mm2, Xd3, Lyd8), five entomopathogenic fungi (Metarhizium flavoviride As2, M. anisopliae KTU-51 and Beauveria bassiana Pa4, Pa5, Hp5), and five baculoviruses (HycuGV-Hc1, LdMNPV-T2, AcMNPV, DapuNPV-T1, SeMNPV-U), applied at concentrations of 1.8 × 109 cfu/mL, 1 × 107 conidia/mL, and 1 × 107 PIB/mL, respectively, against H. derogata larvae under laboratory conditions. Among these, B. thuringiensis subsp. kurstaki Bn1, B. bassiana Pa4, Hyphantria cunea granulovirus (HycuGV-Hc1), and Spodoptera exigua nucleopolyhedrovirus (SeMNPV-U) showed strong insecticidal activity and were selected for virulence assays, each achieving 100% mortality in third instar larvae. The median lethal concentrations (LC50) were determined to be 7.1 × 104 cfu/mL, 3.3 × 103 conidia/mL, 1.2 × 103 PIB/mL, and 1 × 103 PIB/mL, respectively. These results indicate that indigenous microbial agents are a promising environmentally friendly alternative to chemical pesticides in the control of H. derogata.

This article analyses how forms of private cooperation between East and West were reshaped during the late Cold War and beyond. It does so by studying an elitist East–West club, called the International Vienna Council, which brings together leaders of multinational companies and leaders of the planned economy. While the permeability of the iron curtain has been well documented, little is known about the evolution of East–West circulation patterns during that time or the role played by economic elites. The International Vienna Council, initially a forum for ‘parallel diplomacy’, gradually became a platform for concrete business cooperation. The club’s activities continued after 1989, but it struggled with the transition from an East–West club to an interest group within the European Union. These dynamics shed light on the gradual autonomy of a private East–West cooperation group and its contribution to defining a pan-European economic space since the 1970s.

The Pósa–Seymour conjecture determines the minimum degree threshold for forcing the $k$th power of a Hamilton cycle in a graph. After numerous partial results, Komlós, Sárközy, and Szemerédi proved the conjecture for sufficiently large graphs. In this paper, we focus on the analogous problem for digraphs and for oriented graphs. We asymptotically determine the minimum total degree threshold for forcing the square of a Hamilton cycle in a digraph. We also give a conjecture on the corresponding threshold for $k$th powers of a Hamilton cycle more generally. For oriented graphs, we provide a minimum semi-degree condition that forces the $k$th power of a Hamilton cycle; although this minimum semi-degree condition is not tight, it does provide the correct order of magnitude of the threshold. Turán-type problems for oriented graphs are also discussed.

This study was undertaken to investigate the molecular detection of biofilm-producing Staphylococcus aureus (S. aureus) from goat mastitis. An overall 384 milk samples were initially screened for subclinical mastitis (SCM) followed by molecular characterization of S. aureus isolates. The biofilm formation was assessed using Congo Red agar (CRA), a microtiter plate and the presence of the icaA gene. The results revealed a molecular prevalence of 53.24% (115/216) for pathogenic S. aureus in milk samples of goats. The phenotypic prevalence of biofilm production by CRA and microtitre methods was recorded to be 38.26% (44/115) and 26.96% (31/115) respectively, while the molecularly confirmed biofilm-forming S. aureus through polymerase chain reaction targeting icaA gene was 58.26% (67/115). The phylogenetic analysis of icaA gene revealed high identity between sequences of study isolates and the isolates of other neighbouring countries. The antibiogram profiling of pathogenic S. aureus showed increased resistance to cefoxitin and oxytetracycline followed by gentamicin. Out of 115, 45.22% (52/115) were declared as multiple drug resistant with multiple antibiotic resistance index greater than 0.2. The study concluded that biofilm-producing S. aureus strains are considered to be a common cause of SCM in dairy goats of Pakistan and biofilm formation is associated with multidrug resistance of study isolates.

The recent advancements in digital technologies have made remote work a core aspect of modern organizations, bringing opportunities and challenges for employee well-being. Drawing on the Job Demands-Resources model, the study investigates key stressors undermining employees’ well-being within digitalized settings. Fuzzy total interpretive structural modeling (F-TISM) and MICMAC analysis are employed to understand the hierarchical interrelationship and classify the stressors according to their driving and dependence power. The findings reveal low supervisor support, unrealistic supervisor expectations, digital overload, digital fatigue, and constant connectivity as critical drivers undermining remote workers’ well-being in these work practices. The proposed health impairment process of the JD-R model provides theoretical insights into how high job demands in digitalized settings undermine the well-being of remote workers, amid the growing emphasis on digital transition and flexible work models. The developed decision model provides actionable insights for practitioners and policymakers.

Dietary patterns are prerequisites for health and integral components of ecological systems. For over a century researchers have been building a body of evidence of associations between dietary patterns and health and sustainability outcomes while policymakers have been synthesising and translating this evidence into policies to promote public health. During this period, food systems have dramatically changed and driven the emergence of food supplies and dietary behaviours with no ecological or evolutionary precedent. Now, the relevance of conventional nutrition research and policymaking approaches for understanding food system transitions and protecting against unhealthy and unsustainable diets is being questioned. This review aims to examine how the ecological nutrition paradigm might guide a transformed approach to nutrition research and policymaking to promote healthy and sustainable diets. It shows the ecological nutrition paradigm is transdisciplinary integrating biological, social and environmental dimensions into nutrition research and policymaking. The paradigm operates to a ‘fit-for-purpose’ policymaking orientation. It draws on ecological and evolutionary theories to provide insights to conceptualise the causes of, and solutions to, nutrition problems and help design relevant decision-making processes. These research and policymaking features contrast with the ‘one-size-fits-all’ policymaking orientation and prescriptive decision-making processes of the conventional medical nutrition paradigm. Their attention to a relevance criterion engenders confidence in the likely effectiveness, and ability to avoid unintended consequences, of policies informed within an ecological nutrition paradigm. The review proposes a shift to the ecological nutrition paradigm to transform nutrition research and policymaking for promoting healthy and sustainable diets is overdue.
