Somebody is watching me: framing surveillance as rent-seeking behavior
Authors: Dzhurova Albena , Sementelli Arthur 
Published: August 2022

PurposeThis paper examines how contemporary workplace surveillance can simultaneously incentivize and commodify workforce behavior. Specifically, workplace surveillance is reconceptualized as rent-seeking, which offers a framework for analyzing novel employer-employee relationships stemming from alternate views of risk and reward.Design/methodology/approachThe case of workplace microchipping is studied qualitatively as a backdrop for theorizing emergent labor relations in the context of surveillance capitalism and biopolitics.FindingsReconsidering surveillance within the context of personal risk and entrepreneurial lure offers much to 21st century discourse on labor and supervision. It is imperative that the public sector engages in appropriate regulatory protocols to manage emergent behavior in organizations.Originality/valueThis study departs from the popular conceptualization of human microchipping as an intersection of legal and ethical considerations of surveillance. Instead, the authors examine a different aspect of the microchipping phenomenon, taking into account employee creative reactions to employer surveillance in the context of risk and return.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-01-2022-0009
Effects of wall slip on the dynamic characteristics of water-lubricated bearing considering rough contact
Authors: Guo Juan , Han Yanfeng , Chen Shouan , Cai Jianlin , Dai Haiming 
Published: August 2022

Purpose
This paper aims to identify the role of the wall slip on the dynamic characteristics of the multi-groove water-lubricated bearing considering rough contact, including stiffness and damping coefficients of the water film and contact stiffness coefficient of the asperity contact.

Design/methodology/approach
The modified perturbed average Reynolds equations with the wall slip are derived, and the calculated perturbed hydrodynamic pressures are integrated to obtain the stiffness and damping coefficients of the water film. The elastic-plastic contact model of Kogut and Etsion is used to determine the contact stiffness coefficient.

Findings
Numerical results reveal that the wall slip has the more significant impact on the water film stiffness coefficients compared with the damping and contact stiffness coefficients. When the slip angle lies in a reasonable range, the lubrication performance can be effectively improved, especially in the mixed lubrication condition. In addition, it is worth emphasizing that the abrupt change of the water film stiffness coefficients occurs at the region II (pressure zone) in this study.

Originality/value
The influence mechanism of the wall slip on the dynamic characteristics of the water-lubricated bearing considering rough contact is first revealed.

Mechanisms of ultraviolet‐induced melasma formation: A review
Authors: Yang Jian , Zeng Jinrong , Lu Jianyun 
Published: August 2022

AbstractMelasma, a pigmentation disorder, commonly occurs in exposed skin areas and can be attributed to several factors. Ultraviolet radiation (UVR) is the primary factor that induces and aggravates melasma. Considering gene expression, exposed skin areas experience abnormal gene expression, involving melanin metabolism, oxidative stress, impaired skin barrier function, and abnormal composition of nerve factors. From a histological perspective, UVR can cause basement membrane collapse, melanocyte sinking, and disorders of skin lipid metabolism. Emerging therapies have focused on these pathological alterations in melasma, including platelet‐rich plasma, mesotherapy, and phytochemicals. Understanding the role of UVR in the development of melasma can facilitate early prevention and highlight the future direction of melasma treatment.
Do cracks improve the conductive ability of porous rocks?
Authors: Han Tongcheng , Fu Li‐Yun 
Published: August 2022

AbstractCracks widely exist in rocks and are important in various geophysical applications. However, although electrical methods are conventionally employed for the detection and characterization of cracks, the fundamental question whether cracks improve the conductive ability of porous rocks (a quantification of their electrical conductivity if their porosity and saturant are the same) remains largely unaddressed. We address this knowledge gap through theoretical models with confirmed validity. We show that the conductive ability of a rock containing non‐interacting penny‐shaped cracks with random orientation will be improved only in the case when the aspect ratio of the cracks is below a certain value, which is referred to as the critical crack aspect ratio. We also show that the critical crack aspect ratio is uniquely determined by the porosity and electrical conductivity (or cementation exponent) of the porous rock where the cracks reside. We further demonstrate that the critical crack aspect ratio is some representation of the pore structure, and using two times the critical crack aspect ratio as the pore geometry can give rise to a reasonable agreement between modelled and measured P‐ and S‐wave velocities. The critical crack aspect ratio offers a consistent microstructure for the joint elastic–electrical modelling for the improved characterization of cracks through integrated seismic and electrical surveys.

AbstractMultiphysics inversion exploits different types of geophysical data that often complement each other and aims to improve overall imaging resolution and reduce uncertainties in geophysical interpretation. Despite the advantages, traditional multiphysics inversion is challenging because it requires a large amount of computational time and intensive human interactions for preprocessing data and finding trade‐off parameters. These issues make it nearly impossible for traditional multiphysics inversion to be applied as a real‐time monitoring tool for geological carbon storage. In this paper, we present a deep learning (DL) multiphysics network for imaging CO2 saturation in real time. The multiphysics network consists of three encoders for analysing seismic, electromagnetic and gravity data and shares one decoder for combining imaging capabilities of the different geophysical data for better predicting CO2 saturation. The network is trained on pairs of CO2 label models and multiphysics data so that it can directly image CO2 saturation. We use the bootstrap aggregating method to enhance the imaging accuracy and estimate uncertainties associated with CO2 saturation images. Using realistic CO2 label models and multiphysics data derived from the Kimberlina CO2 storage model, we evaluate the performance of the deep learning multiphysics network and compare its imaging results to those from the deep learning single‐physics networks. Our modelling experiments show that the deep learning multiphysics network for seismic, electromagnetic, and gravity data not only improves the imaging accuracy but also reduces uncertainties associated with CO2 saturation images. Our results also suggest that the deep learning multiphysics network for the non‐seismic data (i.e., electromagnetic and gravity) can be used as an effective low‐cost monitoring tool in between regular seismic monitoring.
Drivers of Odonata flight timing revealed by natural history collection data
Authors: Woods Taylor , McGarvey Daniel J. 
Published: August 2022

Abstract

Global change may cause widespread phenological shifts. But knowledge of the extent and generality of these shifts is limited by the availability of phenological records with sufficiently large spatiotemporal extents. Using North American odonates (damselflies and dragonflies) as a model system, we show how a combination of natural history museum and community science collections, beginning in 1901 and extending through 2020, can be leveraged to better understand phenology.

We begin with an analysis of odonate functional traits. Principal coordinate analysis is used to place odonate genera within a three‐dimensional trait ordination. From this, we identify seven distinct functional groups and select a single odonate genus to represent each group. Next, we pair the odonate records with a list of environmental covariates, including air temperature and degree days, photoperiod, precipitation, latitude and elevation. An iterative subsampling process is then used to mitigate spatiotemporal sampling bias within the odonate dataset. Finally, we use path analysis to quantify the direct effects of degree days, photoperiod and precipitation on odonate emergence timing, while accounting for indirect effects of latitude, elevation and year.

Path models showed that degree days, photoperiod and precipitation each have a significant influence on odonate emergence timing, but degree days have the largest overall effect. Notably, the effect that each covariate has on emergence timing varied among functional groups, with positive relationships observed for some group representatives and negative relationships observed for others. For instance, Calopteryx sp. emerged earlier as degree days increased, while Sympetrum sp. emerged later.

Previous studies have linked odonate emergence timing to temperature, photoperiod or precipitation. By using natural history museum and community science data to simultaneously examine all three influences, we show that systems‐level understanding of odonate phenology may now be possible.

Abstract

The direct and indirect effects of climate change can affect, and are mediated by, changes in animal behaviour. However, we often lack sufficient empirical data to assess how large‐scale disturbances affect the behaviour of individuals, which scales up to influence communities.

Here, we investigate these patterns by focusing on the foraging behaviour of butterflyfishes, prominent coral‐feeding fishes on coral reefs, before and after a mass coral bleaching event in Iriomote, Japan.

In response to 65% coral mortality, coral‐feeding fishes broadened their diets, showing a significant weakening of dietary preferences across species.

Multiple species reduced their consumption of bleaching‐sensitive Acropora corals, while expanding their diets to consume a variety of other coral genera. This resulted in decreased dietary overlap among butterflyfishes.

Behavioural changes in response to bleaching may increase resilience of coral reef fishes in the short term. However, coral mortality has reduced populations of coral‐feeders world‐wide, indicating the changes in feeding behaviour we document here may not be sufficient to ensure long‐term resilience of butterflyfishes on coral reefs.
The softstone vessels assemblage from the Long Collective Grave 1 (LCG‐1) at Dibbā al‐Bayah (Sultanate of Oman): A preliminary assessment
Authors: Genchi Francesco , Tursi Giampiero 
Published: August 2022

AbstractThe present contribution aims to provide an overview of the large collection of soft stone vessels and lids coming from the collective tomb Long Collective Grave 1 in the Dibbā al‐Bayah funerary complex, along with a brief description and evaluation of the tomb itself. The corpus of material here discussed has been recovered during the 2012 season, and it mainly encompasses the chronological span between the second and first millennium BC. The findings are classified and organised in tables according to their chronological phase, and successively on the basis of their morphology and decorative patterns to which a major focus is addressed. Given the outstanding manufacturing of the materials, the finely incised and even plastic decorations, and their state of preservation, an assessment of such remarkable corpus, although partial, contributes significantly to the study of the diffusion and production of stone vessels in South‐East Arabia.

Published: August 2022

AbstractA comprehensive remote sensing survey of AlUla County in north‐west Saudi Arabia has revealed 32 examples of the ancient, stone‐built animal traps known as ‘kites’. Noting that most (27) are located on the Ḥarrat ʿUwayriḍ, a satellite survey of parts of that lavafield outside of AlUla County was undertaken, identifying a further 175 kites. These show commonalities with ‘V‐shaped’ kites previously identified in mountainous areas along the western extents of the Arabian Shield in the Sinai Peninsula, Negev Desert and south‐west Saudi Arabia. A study of the form and placement of these kites in their ecological and geological contexts suggests that they are representative of a distinct complex, exhibiting sophisticated morphological adaptations to target specific games over similar terrain.
Piece‐rate cuts and ratchet effects
Authors: Shearer Bruce S. 
Published: August 2022

AbstractI use a quasi experiment, conducted in the field, to evaluate how the workers of an economic firm responded to threats to cut their piece rates. During the study, the piece rate paid to workers was initially set above the regular rate, given working conditions. In a commitment treatment this high rate was paid without any threat of revision. During a non‐commitment trial, the high rate was accompanied by a threat from management to reduce the rate if, after two days of work, average earnings were too high. The empirical results display strong ratchet effects. Workers withheld output by 16% under non‐commitment relative to commitment. The firm eventually reduced the piece rate from the initial high rate, but left it above the regular rate, giving workers the possibility to extract rents. Workers showed no tendency to restrict output during this phase of the study.
The extreme gendering of COVID−19: Household tasks and division of labour satisfaction during the pandemic
Authors: Haney Timothy J. , Barber Kristen 
Published: August 2022

AbstractFor many years, scholars have directed our attention to the gender gap in domestic labour. Even when women engage in paid employment, they nevertheless perform the majority of the household labour in most wealthy countries. At the same time, disasters and crises both expose and exacerbate existing social inequalities. In this paper, we ask: in what ways has the COVID−19 pandemic contributed to the gender gap in household labour, including childcare? How do women and men feel about this gap? Using data from the Canadian Perspectives survey series (Wave 3), conducted by Statistics Canada three months into the pandemic, our analyses consider the task distribution that made household labour intensely unequal during COVID−19, with women ten times more likely than men to say childcare fell mostly on them, for example. Yet, in nearly all of our models, women did not ubiquitously report being more dissatisfied with the division of domestic tasks within the house, nor were they more likely than men to say that the household division of labour “got worse” during COVID; however, parents did feel that it got worse. We discuss what these findings mean for women's mental health, long‐term paid labour, and interpersonal power, and raise questions about why it is we are not seeing a decrease in women's reported satisfaction with this division of labour. These findings spotlight gender inequality and the family as ongoing pillars of capitalism, and how the structural and interpersonal weathering of the pandemic comes at a particularly great expense to women.

AbstractObjectivesExtracellular vesicles (EVs) are key biological mediators of several physiological functions within the cell microenvironment. Platelets are the most abundant source of EVs in the blood. Similarly, platelet lysate (PL), the best platelet derivative and angiogenic performer for regenerative purposes, is enriched of EVs, but their role is still too poorly discovered to be suitably exploited. Here, we explored the contribution of the EVs in PL, by investigating the angiogenic features extrapolated from that possessed by PL.MethodsWe tested angiogenic ability and molecular cargo in 3D bioprinted models and by RNA sequencing analysis of PL‐derived EVs.ResultsA subset of small vesicles is highly represented in PL. The EVs do not retain aggregation ability, preserving a low redox state in human umbilical vein endothelial cells (HUVECs) and increasing the angiogenic tubularly‐like structures in 3D endothelial bioprinted constructs. EVs resembled the miRNome profile of PL, mainly enriched with small RNAs and a high amount of miR‐126, the most abundant angiogenic miRNA in platelets. The transfer of miR‐126 by EVs in HUVEC after the in vitro inhibition of the endogenous form, restored angiogenesis, without involving VEGF as a downstream target in this system.ConclusionPL is a biological source of available EVs with angiogenic effects involving a miRNAs‐based cargo. These properties can be exploited for targeted molecular/biological manipulation of PL, by potentially developing a product exclusively manufactured of EVs.
A neuropsychological approach to differentiating cannabis‐induced and primary psychotic disorders

Published: August 2022

AbstractAimRates of cannabis use are elevated in early psychosis populations, rendering it difficult to determine if an episode of psychosis is related to cannabis use (e.g., cannabis‐induced psychosis), or if substance use is co‐occurring with a primary psychotic disorder (e.g., schizophrenia). Clinical presentations of these disorders are often indistinguishable, hindering assessment and treatment. Despite substantial research identifying cognitive deficits, eye movement abnormalities and speech impairment associated with primary psychotic disorders, these neuropsychological features have not been explored as targets for diagnostic differentiation in early psychosis.MethodsEighteen participants with cannabis‐induced psychosis (Mage = 21.9, SDage = 4.25, 14 male) and 19 participants with primary psychosis (Mage = 29.2, SDage = 7.65, 17 male) were recruited from early intervention programs. Diagnoses were ascertained by primary treatment teams after a minimum of 6 months in the program. Participants completed tasks assessing cognitive performance, saccadic eye movements and speech. Clinical symptoms, trauma, substance use, premorbid functioning and illness insight were also assessed.ResultsRelative to individuals with primary psychosis, individuals with cannabis‐induced psychosis demonstrated significantly better performance on the pro‐saccade task, faster RT on pro‐ and anti‐saccade tasks, better premorbid adjustment, and a higher degree of insight into their illness. There were no significant differences between groups on psychiatric symptoms, premorbid intellectual functioning, or problems related to cannabis use.ConclusionsIn early stages of illness, reliance on traditional diagnostic tools or clinical interviews may be insufficient to distinguish between cannabis‐induced and primary psychosis. Future research should continue to explore neuropsychological differences between these diagnoses to improve diagnostic accuracy.

AbstractDiabetes can cause vascular remodelling and is associated with worse outcome after ischaemic stroke. Pioglitazone is a commonly used anti‐diabetic agent. However, it is not known whether pioglitazone use before ischaemia could reduce brain ischaemic injury. Pioglitazone was administered to 5‐week‐old db+ or db/db mice. Cerebral vascular remodelling was examined at the age of 9 weeks. Expression of peroxisome proliferator‐activated receptor‐γ (PPARγ), p‐PPARγ (S112 and S273), nucleotide‐binding domain (NOD)‐like receptor protein 3 (Nlrp3), interleukin‐1β (IL‐1β) and tumour necrosis factor‐α (TNF‐α) was evaluated in the somatosensory cortex of mice. Neurological outcome was evaluated 24 h after brain ischaemia. Results showed that early pioglitazone treatment provided a long‐lasting effect of euglycaemia but enhanced hyperlipidaemia in the db/db mice. Diabetic mice exhibited increased vascular tortuosity, narrower middle cerebral artery (MCA) width and IgG leakage in the brain. These changes were blocked by early pioglitazone treatment. In diabetic animals, PPARγ expression was reduced, and p‐PPARγ at S273 but not S112, Nlrp3, IL‐1β and TNF‐α were increased in the somatosensory cortex. PPARγ decrease and Nlrp3 increase were mainly in the neurons of the diabetic brain, which was reversed by early pioglitazone treatment. Pioglitazone attenuated the aggravated neurological outcome after stroke in diabetic mice. But this protective effect was abolished through restoring cerebral inflammation by intracerebroventricular administration of IL‐1β and TNF‐α in pioglitazone‐treated diabetic mice before MCAO. In summary, early pioglitazone treatment attenuates cerebral vascular remodelling and ischaemic brain injury possibly via blocking chronic neuroinflammation in the db/db mice.
