From a ‘Decent Work’ Approach to a Marxist Analysis of Labour Control and Labour Agency in Global Production: Reviewing Research on Labour in GPNs
Authors: López Tatiana 
Published: March 2023

AbstractThis chapter reviews literature on labour in GVCs and GPNs. It argues that within the interdisciplinary literature on labour issues in GVCs/GPNs, two parallel research strands have emerged that are characterised by very different conceptual approaches: (1) a ‘Decent Work’ approach underpinned by the institutionalist perspective of the ILO Decent Work Agenda and (2) a ‘Marxist Political Economy’ approach, which is based on the assumption that the exploitation of labour is an inherent structural feature of capitalist production systems. Situating this study within the second research strand, this chapter then reviews the contributions and shortcomings of existing literature on labour control and labour agency in GVCs/GPNs. In doing so, the chapter highlights the limitations of existing scalar approaches for studying labour control and labour agency in GVCs/GPNs, which have not paid enough attention to how dynamics of labour control and labour agency at different levels influence each other. Against this background, this chapter argues that to gain a more nuanced understanding of the ‘architectures of labour control’ underpinning specific GPNs as well as of workers’ and unions’ networked agency strategies, a relational analytical approach can be beneficial.
Spin 2 spectrum for marginal deformations of 4d $$ \mathcal{N} $$ = 2 SCFTs

Abstract
We compute spin 2 spectrum associated with massive graviton fluctuations in γ-deformed Gaiotto-Maldacena background those are holographically dual to marginal deformations of $$ \mathcal{N} $$
N
= 2 SCFTs in four dimensions. Under the special circumstances, we analytically estimate the spectra both for the γ-deformed Abelian T dual (ATD) as well as the non-Abelian T dual (NATD) cases where we retain ourselves upto leading order in the deformation parameter. Our analysis reveals a continuous spectra which is associated with the breaking of the U(1) isometry (along the directions of the internal manifold) in the presence of the γ-deformation. We also comment on the effects of adding flavour branes into the picture and the nature of the associated spin 2 operators in the dual $$ \mathcal{N} $$
N
= 1 SCFTs.

AbstractVertebrate lonesome kinase (VLK) is the only known secreted tyrosine kinase and responsible for the phosphorylation of a broad range of secretory pathway-resident and extracellular matrix proteins. However, its cell-type specific functions in vivo are still largely unknown. Therefore, we generated mice lacking the VLK gene (protein kinase domain containing, cytoplasmic (Pkdcc)) in mesenchymal cells. Most of the homozygous mice died shortly after birth, most likely as a consequence of their lung abnormalities and consequent respiratory failure. E18.5 embryonic lungs showed a reduction of alveolar type II cells, smaller bronchi, and an increased lung tissue density. Global mass spectrometry-based quantitative proteomics identified 97 proteins with significantly and at least 1.5-fold differential abundance between genotypes. Twenty-five of these had been assigned to the extracellular region and 15 to the mouse matrisome. Specifically, fibromodulin and matrilin-4, which are involved in extracellular matrix organization, were significantly more abundant in lungs from Pkdcc knockout embryos. These results support a role for mesenchyme-derived VLK in lung development through regulation of matrix dynamics and the resulting modulation of alveolar epithelial cell differentiation.

Published: March 2023

AbstractIncreasing evidence suggests that nearshore turbid coral reefs may mitigate bleaching of reef building calcifiers and play a critical role in the future of marine biodiversity in coastal areas. However, biomineralization processes on turbid reefs are relatively understudied compared to clear water counterparts and most published work focuses on corals. Here, we investigate how the mixotrophic giant clam Tridacna squamosa, a bivalve with ecological, cultural and economic significance, grows across a mosaic of less turbid to turbid reefs in the Coral Triangle. We construct growth chronologies from live and dead collected shells by measuring daily growth increments with petrography and scanning electron microscopy (SEM) to gain insight into growth rate on daily, seasonal and annual scales. We find annual growth is not significantly different across a turbidity gradient when scaled to ontogeny, while seasonal growth highly varies. Kd(490) (a measurement positively correlated with turbidity) and chlorophyll-a are likely important factors driving seasonal growth on a turbid reef near a river, compared to sea surface temperature (SST), cloud cover and rainfall on a less turbid reef. On a daily scale, we investigate increment microstructure and spectral characteristics of chronologies, finding a relationship between tidal range and daily increments. Overall, our results indicate that light-enhanced calcification is likely most important in the less turbid reef, compared to heterotrophic feeding in the turbid reef. The trophic plasticity of T. squamosa may allow for its sustained growth in marginal conditions, supporting evidence that these habitats serve as important conservation hotspots for diverse reef building taxa.

AbstractObjectivesCag A+Helicobacter pylorichronic infection cause malignant transformation of the human gastric mucosa. N6-methyladenosine (m6A) modifications are the most common and abundant mRNA modifications and one of the pathways affecting tumorigenicity and tumor progression. However, the role of m6A modification in the process of chronicH. pyloriinfection leading to malignant transformation of gastric mucosa is unclear.MethodsIn this study, we used Cag A−and Cag A+H. pylorichronic infection to establish cellular models in GES-1 cells and analyzed the cellular morphology, proliferation, apoptosis, invasiveness and tumorigenicity of gastric mucosal epithelial cells. The m6A expression levels of GES-1 cells after chronic infection with Cag A−and Cag A+H. pyloriwere examined, and modifying effect of FTO (the fat mass and obesity-associated protein) on CD44 was verified by MeRIP–qPCR. Finally, the FTO expression changes and m6A expression levels were further validated in clinical gastric cancer tissues.ResultsChronic Cag A+H. pylori-infected GES-1 cells exhibit altered cell morphology, apoptosis inhibition, abnormal proliferation, enhanced migration, colony formation, and increased stem cell-like properties. Meanwhile, FTO and CD44 expression was enhanced, and FTO may induce malignant transformation of gastric mucosa by regulating CD44 mRNA m6A methylation modifications.ConclusionsWe verified the effect of chronic stimulation of Cag A+H. pylorion malignant transformation of gastric mucosal epithelium. revealing the possibility of FTO in promoting malignant transformation of gastric mucosa by modifying CD44 mRNA methylation, suggesting that FTO expression is a potential molecule for malignant transformation of gastric mucosal epithelial cells.

AbstractConsider a graph where each of thennodes is either in state$$\mathcal {R}$$Ror$$\mathcal {B}$$B. Herein, we analyze thesynchronousk-Majoritydynamics, where in each discrete-time round nodes simultaneously samplekneighbors uniformly at random with replacement and adopt the majority state among those of the nodes in the sample (breaking ties uniformly at random). Differently from previous work, we study the robustness of thek-Majorityinmaintaining a$$\mathcal {R}$$Rmajority, when the dynamics is subject to two forms ofbiastoward state$$\mathcal {B}$$B. The bias models an external agent that attempts to subvert the initial majority by altering the communication between nodes, with a probability of successpin each round: in the first form of bias, the agent tries to alter the communication links by transmitting state$$\mathcal {B}$$B; in the second form of bias, the agent tries to corrupt nodes directly by making them update to$$\mathcal {B}$$B. Our main result shows asharp phase transitionin both forms of bias. By considering initial configurations in which every node has probability$$q \in (\frac{1}{2},1]$$q∈(12,1]of being in state$$\mathcal {R}$$R, we prove that for every$$k\ge 3$$k≥3there exists a critical value$$p_{k,q}^\star $$pk,q⋆such that, with high probability, the external agent is able to subvert the initial majority either in$$n^{\omega (1)}$$nω(1)rounds, if$$p<p_{k,q}^\star $$p<pk,q⋆, or inO(1) rounds, if$$p>p_{k,q}^\star $$p>pk,q⋆. When$$k<3$$k<3, instead, no phase transition phenomenon is observed and the disruption happens inO(1) rounds for$$p>0$$p>0.
A giant raptor (Aves: Accipitridae) from the Pleistocene of southern Australia

Published: March 2023

AbstractThe giant accipitridDynatoaetus gaffaegen. et sp. nov. is described from existing and newly collected material. Initial fossil remains were collected from Mairs Cave (Flinders Ranges, South Australia) in 1956 and 1969, and comprised a sternum, distal humerus and two ungual phalanges. A further 28 bones from this individual—including the neurocranium, vertebrae, furculum, and additional wing and leg bones, most of which were incomplete—were discovered at the site in 2021. This allowed identification of additional fossils from the same species in collections from Cooper Creek (Lake Eyre Basin, SA), Victoria Fossil Cave (Naracoorte, SA) and Wellington Caves (Wellington, NSW).Dynatoaetushas variable similarity across elements to those of living species in the Perninae, Gypaetinae, Circaetinae and Aegypiinae. Parsimony and Bayesian phylogenetic analyses of combined morphological and DNA data resolved it as the immediate sister-group to the Aegypiinae within the Circaetinae + Aegypiinae clade. The robust and eagle-like morphology of the lower hindlimbs suggest that the species was a predator, rather than a scavenger, and thus functionally similar to large circaetines such as the Philippine EaglePithecophaga jefferyi. Furthermore, this new species is the largest known bird of prey from Australia, much larger than the modern Wedge-Tailed EagleAquila audax. It is outsized in Australasia only by femaleHieraaetus moorei(the extinct Haast’s Eagle from New Zealand). It is inferred to have been Australia’s top terrestrial avian predator during the Pleistocene, ranging from arid inland Australia to the more temperate coast, and likely became extinct around the time of the megafaunal mass extinction which peaked around 50 Ka. Its extinction in the late Pleistocene, along with the recently described scavenging vultureCryptogyps lacertosus, marked a distinct decline in the diversity and function of Australia’s raptor guild.
Beyond a neoliberal critique of hunger: a genealogy of food charity in Aotearoa New Zealand
Authors: Riol Katharine S. E. Cresswell , Connelly Sean 
Published: March 2023

AbstractSince the 1980s, foodbanks have become a widespread solution to addressing hunger within high-income countries. The primary reason for their establishment has been widely recognised as neoliberal policies, particularly those that led to massive cuts in social welfare assistance. Foodbanks and hunger have subsequently been framed within a neoliberal critique. However, we argue that critiques of foodbanks are not unique to neoliberalism but have deeper historical roots, meaning that the part neoliberal policies have played is not as clear-cut. In order to understand the normalisation of foodbanks within society, and gain a more extensive understanding of hunger and appreciation as to how this issue could be addressed, it is therefore important to gain a historical understanding of food charity development. In this article, we achieve this by presenting a genealogy of food charity within Aotearoa New Zealand, which witnessed a fluctuation in the use of soup kitchens during the nineteenth and twentieth centuries, and a rise of foodbanks in the 1980s and ‘90 s. Highlighting the historical parallels and major economic and cultural shifts that have allowed for the institutionalisation of foodbanks, we explore the patterns, parallels and differences exposed, and how they yield an alternative understanding of hunger. Using this analysis, we then discuss the wider implications of the historical foundations of food charity and hunger to better understand the role neoliberalism has played in the entrenchment of foodbanks, and advocate the importance of looking beyond a neoliberal critique in order to entertain alternative solutions to addressing food insecurity.
Dissolved oxygen saturation is crucial for gas bladder inflation in turquoise killifish (Nothobranchius furzeri)
Authors: Žák Jakub , Anil Abhishek Nair , Dyková Iva 
Published: March 2023

AbstractProviding optimal conditions for early-life gas bladder inflation of captive fish is one of the biggest challenges in fish culture. It also applies to laboratory fishes. Turquoise killifish (Nothobranchius furzeri Jubb, 1971) is a popular research model in biogerontology due to its short lifespan. Annual killifish in laboratory culture frequently suffer from an inability to inflate their gas bladder which may stem from suboptimal environmental conditions in captivity. Here, we investigate (1) the effect of dissolved oxygen (DO) saturation and (2) access to the water surface on gas bladder inflation and hatching success of turquoise killifish. We further histologically examine the gas bladder development from its primordial form to full inflation. In accordance with physoclistous nature of turquoise killifish, access to the water surface is not necessary for gas bladder inflation. We found that hatching success was highest in the treatment with constant or decreasing DO saturation. In contrast, the highest proportion of larvae with inflated gas bladders was found in the treatment with DO oversaturated water (130%) which was induced by the addition of an oxygen tablet. Larvae inflated their gas bladders within 2 to 48 h post-hatching. These findings represent a major step toward a solution to a persistent problem in laboratory culture of this increasingly important model organism.
Finite-trace and generalized-reactivity specifications in temporal synthesis

Published: March 2023

AbstractLinear Temporal Logic (LTL) synthesis aims at automatically synthesizing a program that complies with desired properties expressed in LTL. Unfortunately it has been proved to be too difficult computationally to perform full LTL synthesis. There have been two success stories with LTL synthesis, both having to do with the form of the specification. The first is the GR(1) approach: use safety conditions to determine the possible transitions in a game between the environment and the agent, plus one powerful notion of fairness, Generalized Reactivity(1), or GR(1). The second, inspired by AI planning, is focusing on finite-trace temporal synthesis, with LTL$$_f$$

f

(LTL on finite traces) as the specification language. In this paper we take these two lines of work and bring them together. We first study the case in which we have an LTL$$_f$$

f

agent goal and a GR(1) environment specification. We then add to the framework safety conditions for both the environment and the agent, obtaining a highly expressive yet still scalable form of LTL synthesis.

AbstractFirefly flashes are well-known visual signals used by these insects to find, identify, and choose mates. However, many firefly species have lost the ability to produce light as adults. These “unlighted” species generally lack developed adult light organs, are diurnal rather than nocturnal, and are believed to use volatile pheromones acting over a distance to locate mates. While cuticular hydrocarbons, which may function in mate recognition at close range, have been examined for a handful of the over 2000 extant firefly species, no volatile pheromone has ever been identified. In this study, using coupled gas chromatography - electroantennographic detection, we detected a single female-emitted compound that elicited antennal responses from wild-caught male winter fireflies, Photinus corruscus. The compound was identified as (1S)-exo-3-hydroxycamphor (hydroxycamphor). In field trials at two sites across the species’ eastern North American range, large numbers of male P. corruscus were attracted to synthesized hydroxycamphor, verifying its function as a volatile sex attractant pheromone. Males spent more time in contact with lures treated with synthesized hydroxycamphor than those treated with solvent only in laboratory two-choice assays. Further, using single sensillum recordings, we characterized a pheromone-sensitive odorant receptor neuron in a specific olfactory sensillum on male P. corruscus antennae and demonstrated its sensitivity to hydroxycamphor. Thus, this study has identified the first volatile pheromone and its corresponding sensory neuron for any firefly species, and provides a tool for monitoring P. corruscus populations for conservation and further inquiry into the chemical and cellular bases for sexual communication among fireflies.
Boltzmann’s Entropy During Free Expansion of an Interacting Gas
Authors: Chakraborti Subhadip , Dhar Abhishek , Kundu Anupam 
Published: March 2023

AbstractIn this work, we study the evolution of Boltzmann’s entropy in the context of free expansion of a one-dimensional interacting gas inside a box. Our interacting particle model is a gas of hard point particles with alternating masses, a system known to have good ergodicity properties. Boltzmann’s entropy is defined for single microstates and is given by the phase-space volume occupied by microstates with the same value of macrovariables which are coarse-grained physical observables. We demonstrate the idea of typicality in the growth of the Boltzmann’s entropy for two choices of macro-variables—the single particle phase space distribution and the hydrodynamic fields. Due to the presence of interactions, the growth curves for both these entropies are observed to converge to a monotonically increasing limiting curve, on taking the appropriate order of limits, of large system size and small coarse-graining scale. Moreover, we observe that the limiting growth curves for the two choices of entropies are identical as implied by local thermal equilibrium. We also discuss issues related to finite size and finite coarse gaining scale which lead to interesting features such as oscillations in the entropy growth curve. We also discuss shocks observed in the hydrodynamic fields.
Investigating Maternal Perspectives of Breastfeeding Support Targeted Towards Fathers in the Milk Man Mobile App Intervention

Published: March 2023

Abstract
Background
The support of her infant’s father is one of the most important factors influencing a mother’s breastfeeding success, and an increasing number of interventions are targeted towards fathers. Engaging fathers as agents to influence a maternal behavior is potentially problematic, yet few studies report on maternal experiences.

Objective
This study aims to explore mothers’ perspectives of their partners’ use of Milk Man, a father-focused breastfeeding smartphone app, and the acceptability of this approach.

Materials and methods
New mothers (N = 459) whose partners had access to the app completed a questionnaire at six weeks postpartum. These data were used to determine knowledge, use and perspectives of the app. A sentiment analysis was conducted on responses to an open-ended question seeking maternal perspectives of the app.

Results
Just over a quarter of mothers (28%) had been shown something from the app, and 37% had discussed something from Milk Man with their partner. There were 162 open-ended responses related to mothers’ perspectives of the app. Relevant responses (n = 129) were coded to an overall sentiment node and then to a total of 23 child nodes (sub-nodes). Most comments were positive (94), with a smaller number either negative (25) or neutral (21). Negative comments related to the usability of the app and not its intent or content.

Conclusion
Mothers found the father-focussed breastfeeding app to be acceptable. When designing interventions targeting one group to affect the behaviour of another, inclusion of measures to gain the perspectives of both should be seen as an imperative.
The independence solution to grue
Authors: Warren Jared 
Published: March 2023

AbstractThe paper presents a comprehensive solution to the new riddle of induction. Gruesome induction is blocked because “grue” is not independent of our sampling and observation methods. Before presenting my theory, I critically survey previous versions of what I call the “independence strategy”, tracing the strategy to three different papers from 1970s by (respectively) Wilkerson, Moreland, and Jackson. Next I critically examine recent approaches by Okasha, Godfrey-Smith, Schramm, and Freitag. All of these approaches have their virtues, but none of them rules out every problem case. Nor do any of them alone explain exactly what goes wrong in all types of gruesome reasoning. My account aims to do both. Learning lessons from my criticisms of previous theories, I argue that there are several crucial types of independence. Correct characterizations of all of them are needed to rule out every problem case. I close by suggesting that the independence solution can be adopted by other approaches—Bayesians, fans of natural kinds, and pragmatists.
