The cycle of commodification: migrant labour, welfare, and the market in global China and Vietnam
Authors: Lin Jake , Nguyen Minh T. N. 
Published: July 2021

AbstractChina and Vietnam have experienced waves of labour and welfare reform since both countries shifted to market socialism, pursuing a development model that depends on the labour of millions of rural–urban migrants in global factories. Their similar development trajectories are productive for theorizing the relationship between labour and welfare. This article conceptualises the two countries’ distinctive regime of migrant labour welfare as integral to a cycle of commodification that encompasses the overlapping processes of commodification, de-commodification and re-commodification of labour. After decades of collectivized labour under state socialism, the cycle begins with the commodification of labour through market reforms that led to mass rural–urban migration and the rise of the global factory alongside the dismantling of the former socialist welfare system. It was then followed by de-commodification attempts aimed at providing forms of social protection that offset the labour precarity caused by decades of labour market liberalisation. Despite the emergence of new universal welfare programs, the market has increasingly intruded into social protection, especially through financialized products targeted at the labouring masses who must compensate for the failings of public welfare programs. As such, these welfare regimes are undergoing a process of re-commodification in which the protection of labour is re-embedded into the market as a commodity to be consumed by the migrant workers with their meagre wages. The “cycle of commodification” offers an analytical framework to understand welfare regimes as a social and political field that keeps evolving in response to the changing global valuation of labour.

BACKGROUND:
The critical view of safety (CVS) is poorly adopted in surgical practices, although it is recommended ubiquitously to prevent major bile duct injuries during laparoscopic cholecystectomy (LC). This study aimed to investigate whether performing a short intraoperative time-out can improve CVS implementation.

STUDY DESIGN:
In this before vs after study, surgeons performing LCs at an academic center were invited to use a 5-second long time-out to verify CVS before dividing the cystic duct (5-second rule). The primary aim was to compare the rate of CVS achievement for LC performed in the year before vs the year after implementation of the 5-second rule. The CVS achievement rate was computed after exclusion of bailout procedures using a mediated video-based assessment made by 2 independent reviewers. Clinical outcomes, LC workflows, and postoperative reports were also compared.

RESULTS:
Three hundred and forty-three of 381 LC performed between December 2017 and November 2019 (171 before and 172 after implementation of the 5-second rule) were analyzed. The 5-second rule was associated with a significantly increased rate of CVS achievement (15.9% vs 44.1% before vs after the 5-second rule, respectively; p < 0.001). Significant differences were also observed with respect to the rate of bailout procedures (8.2% vs 15.7%; p = 0.04), median time (hours:minutes:seconds) to clip the cystic duct or artery (00:17:26; interquartile range 00:11:48 to 00:28:35 vs 00:23:12; interquartile range 00:14:29 to 00:31:45 duration; p = 0.007), and the rate of postoperative CVS reporting (1.3% vs 28.8%; p < 0.001). Postoperative morbidity was comparable (1.8% vs 2.3%; p = 0.68).

CONCLUSIONS:
Performing a short intraoperative time-out was associated with an improved CVS achievement rate. Systematic intraoperative cognitive aids should be studied to sustain the uptake of guidelines.
How Venture Capital Firms Choose Syndication Partners: The Moderating Effects of Institutional Uncertainty and Investment Preference

Published: July 2021

ABSTRACTThis study investigates how venture capital firms (VCs) choose syndication partners. Exponential random graph models of Chinese VC syndication networks from 2006 to 2013 show that the homophily mechanism does not always determine VCs’ partner selection. In selecting partners, VCs have to strike a balance between reducing uncertainty and mobilizing heterogeneous resources. Therefore, decisions about partners depend on institutional uncertainty and VCs’ investment preferences. While VCs that focus on traditional business in an immature market are more likely to form homogeneous syndications, their peers that prefer to invest in innovative companies and that can rely on a stable market tend to syndicate with heterogeneous partners.
A Thousand Flowers on the Road to Epistemic Anarchy: Comments on Chakravartty's Scientific Ontology
Authors: Bryant Amanda 
Published: July 2021

ABSTRACTI introduce the symposium on Anjan Chakravartty's Scientific Ontology by summarizing the book's main claims. In my commentary, I first challenge Chakravartty's claim that naturalized metaphysics cannot be indexed to science simpliciter. Second, I argue that there are objective truths regarding what conduces to particular epistemic aims, and that Chakravartty is therefore too permissive regarding epistemic stances and their resultant ontologies. Third, I argue that it is unclear what stops epistemic stances from having unlimited influence. Finally, I argue that Chakravartty's epistemic stance voluntarism is inadequately motivated and lacks empirical support for its psychological content.
A clinical review of human disease due to Paragonimus kellicotti in North America
Authors: Coogle Brianna , Sosland Samuel , Bahr Nathan C. 
Published: July 2021

AbstractHuman autochthonous infections with the trematode Paragonimus kellicotti are increasingly being reported in North America, but the true prevalence and geographic distribution are unknown. Ingestion of raw crayfish is reported in most human cases, typically in the context of alcohol intoxication. Risk of infection varies depending on what part of the crayfish is ingested as metacercariae of P. kellicotti (>50% mature to adults) localize to the heart and pericardium of the crayfish. Reported human cases have manifested primarily in otherwise healthy young adults presenting with severe eosinophilic pneumonia, pleuritis, systemic symptoms, dermatologic lesions and cerebral involvement. However, it is likely that many infections go unreported due to lack of awareness, mild illness or the absence of rapid commercially available diagnostic tests. Promising advances have been made related to novel diagnostic targets. Conservation of these antigen targets among at least four Paragonimus species could make these antigens viable for diagnostic testing of P. kellicotti specifically as well as other Paragonimus species, but additional studies and funding investments are required. Public and physician awareness may have improved due to targeted education campaigns, but ongoing activities to raise awareness are needed, particularly in areas where cases have not been frequently reported to date.

AbstractThe taxonomy of ruminant Trypanosoma theileri and its relatives (Kinetoplastida: Trypanosomatidae) is controversial, with recent phylogenetic studies segregating T. theileri in cattle and other ruminants worldwide into two major genetic lineages (the TthI and TthII clades) based on genetic markers. In the present study, T. theileri-like trypanosomes isolated from Honshu sika deer (Cervus nippon) in the western Japan (YMG isolate) were genetically characterized using a number of genetic markers. Sika deer trypanosomes of the YMG isolate were genetically different from the Trypanosoma sp. TSD1 isolate previously recorded from Hokkaido sika deer in northern Japan, with the former trypanosome isolate being genetically closer to European cervid trypanosomes and the bovine T. theileri TthII lineage. In contrast, the latter isolate exhibited greater relatedness to North American cervid trypanosomes and the bovine T. theileri TthI lineage, although a clear genetic distinction between these was apparent. Furthermore, trypanosomes in Honshu sika deer from the central part of Japan harboured additional genetic diversity and were closer to either TSD1 or YMG isolates, while distinct from known T. theileri-related genotypes. Importantly, cervids and wild ruminants worldwide might harbour divergent descendants of a T. theileri ancestor, which exhibit rigid host specificity to either bovines or cervid species.
‘Keep calm, stay safe, and drink bubble tea’: Commodifying the crisis of Covid-19 in Singapore advertising
Authors: Starr Rebecca Lurie , Go Christian , Pak Vincent 
Published: July 2021

AbstractAdvertisements employ multimodal configurations of semiotic resources in an effort to lead consumers to draw particular meanings from desired consumption behaviors. This analysis examines the deployment of such resources in advertising during the global Covid-19 pandemic, focusing on the Southeast Asian nation of Singapore. We identify five discourses that offer distinct framings of Covid-19 as a challenge for workers, a wellness issue, a threat to home and family, a challenge for women, and a threat to the Singapore lifestyle. Undergirded by neoliberal notions such as the productivity imperative, these discourses rationalize a range of consumer behaviors as necessary and justified in the struggle to defeat the virus. Advertisements are argued to place the burden of navigating the pandemic primarily on women via the evocation of power femininity. We propose a new framework, crisis commodification, as a means of understanding the ideological mechanisms at play in Covid-19 advertising.

Biological sensitivity to context as a dyadic construct: An investigation of child–parent RSA synchrony among low-SES youth

Published: July 2021

AbstractParenting behaviors are significantly linked to youths’ behavioral adjustment, an association that is moderated by youths’ and parents’ self-regulation. The biological sensitivity to context theory suggests that respiratory sinus arrhythmia (RSA) indexes youths’ varying susceptibility to rearing contexts. However, self-regulation in the family context is increasingly viewed as a process of “coregulation” that is biologically embedded and involves dynamic Parent×Child interactions. No research thus far has examined physiological synchrony as a dyadic biological context that may moderate associations between parenting behaviors and preadolescent adjustment. Using a two-wave sample of 101 low-socioeconomic status (SES) families (children and caretakers; mean age 10.28 years), we employed multilevel modeling to examine dyadic coregulation during a conflict task, indicated by RSA synchrony, as a moderator of the linkages between observed parenting behaviors and preadolescents’ internalizing and externalizing problems. Results showed that high dyadic RSA synchrony resulted in a multiplicative association between parenting and youth adjustment. High dyadic synchrony intensified the relations between parenting behaviors and youth behavior problems, such that in the context of high dyadic synchrony, positive and negative parenting behaviors were associated with decreased and increased behavioral problems, respectively. Parent–child dyadic RSA synchrony is discussed as a potential biomarker of biological sensitivity in youth.

SummarySperm DNA fragmentation can be produced in one (ssSDF) or both (dsSDF) DNA strands, linked to difficulties in naturally achieving a pregnancy and recurrent miscarriages, respectively. The techniques more frequently used to select sperm require centrifugation, which may induce sperm DNA fragmentation (SDF). The objective of this study was to assess whether the microfluidic-based device FertileChip® (now ZyMot®ICSI) can diminish the proportion of sperm with dsSDF. First, in a blinded split pilot study, the semen of nine patients diagnosed with ≥60% dsSDF, was divided into three aliquots: not processed, processed with FertileChip®, and processed with swim up. The three aliquots were all analyzed using neutral COMET for the detection of dsSDF, resulting in a reduction of 46% (P < 0.001) with FertileChip® (dsSDF: 34.9%) compared with the ejaculate and the swim up (dsSDF: 65%). Thereafter, the FertileChip® was introduced into clinical practice and a cohort of 163 consecutive ICSI cycles of patients diagnosed with ≥60% dsSDF was analyzed. Fertilization rate was 75.41%. Pregnancy rates after the first embryo transfer were 53.2% (biochemical), 37.8% (clinical), 34% (ongoing) and the live birth rate was 28.8%. Cumulative pregnancy rates after one (65.4% of patients), two (27.6% of patients) or three (6.4% of patients) transfers were 66% (biochemical), 56.4% (clinical), 53.4% (ongoing) and the live birth rate was 42%. The selection of spermatozoa using Fertile Chip® significantly diminishes the percentage of dsSDF, compared with either the fresh ejaculate or after swim up. Its applicability in ICSI cycles of patients with high dsSDF resulted in good laboratory and clinical outcomes.
Systematic Review and Meta-analysis of Outcome after Mild Traumatic Brain Injury in Older People

Published: July 2021

AbstractObjective:Older age is often identified as a risk factor for poor outcome from traumatic brain injury (TBI). However, this relates predominantly to mortality following moderate–severe TBI. It remains unclear whether increasing age exerts risk on the expected recovery from mild TBI (mTBI). In this systematic review of mTBI in older age (60+ years), a focus was to identify outcome through several domains – cognition, psychological health, and life participation.Methods:Fourteen studies were identified for review, using PRISMA guidelines. Narrative synthesis is provided for all outcomes, from acute to long-term time points, and a meta-analysis was conducted for data investigating life participation.Results:By 3-month follow-up, preliminary findings indicate that older adults continue to experience selective cognitive difficulties, but given the data it is possible these difficulties are due to generalised trauma or preexisting cognitive impairment. In contrast, there is stronger evidence across time points that older adults do not experience elevated levels of psychological distress following injury and endorse fewer psychological symptoms than younger adults. Meta-analysis, based on the Glasgow Outcome Scale at 6 months+ post-injury, indicates that a large proportion (67%; 95% CI 0.569, 0.761) of older adults can achieve good functional recovery, similar to younger adults. Nevertheless, individual studies using alternative life participation measures suggest more mixed rates of recovery.Conclusions:Although our initial review suggests some optimism in recovery from mTBI in older age, there is an urgent need for more investigations in this under-researched but growing demographic. This is critical for ensuring adequate health service provision, if needed.

AbstractWireless connectivity has been realized for multiple environments and different frequency bands. However, little research exists about mmWave communication in industrial environments. This paper presents the 60 GHz double-directional radio channel for mmWave communication in a ship hull for Line-of-Sight (LOS) and non-Line-of-Sight (NLOS) conditions. We performed channel measurements using the Terragraph channel sounder at different locations in the ship hull and fitted LOS path loss to a one-slope path loss model. Path loss and root-mean-square delay spread of the LOS path is compared to the reflected path with lowest path loss. NLOS communication via this first-order reflected path is modeled by calculating the path distance and determining the reflection loss. The reflection losses have a considerable contribution to the signal attenuation of the reflected path. The channel models are implemented in an indoor coverage prediction tool, which was extended with a ray launching algorithm and validated by comparison with an analytical electromagnetic solver. The results show that the mmWave radio channel allows high-throughput communication within a ship hull compartment, even when no LOS path between the transmitter and receiver is present.

AbstractWarming in Central Asia has been accelerating over the past three decades and is expected to intensify through the end of this century. Here, we develop a summer temperature reconstruction for western Mongolia spanning eight centuries (1269–2004 C.E.) using delta blue intensity measurements from annual rings of Siberian larch. A significant cooling response is observed in the year following major volcanic events and up to five years post‐eruption. Observed summer temperatures since the 1990s are the warmest over the past eight centuries, an observation that is also well captured in Coupled Model Intercomparison Project (CMIP5) climate model simulations. Projections for summer temperature relative to observations suggest further warming of between ∼3°C and 6°C by the end of the century (2075–2099 cf. 1950–2004) under the representative concentration pathways 4.5 and 8.5 (RCP4.5 and RCP8.5) emission scenarios. We conclude that projected future warming lies beyond the range of natural climate variability for the past millennium as estimated by our reconstruction.

AbstractSurface raindrop size distributions over a rain shadow region during the Indian summer monsoon are clustered using the k‐means algorithm. The rainfall for five dominant clusters has distinct vertical features in polarimetric radar and micro rain radar. The deep convection with low cloud bases and high liquid water is associated with sharply increasing radar reflectivity at low levels and the largest drops at the surface. The large drops, originated by ice processes, break while falling below the melting layer, causing a peak in raindrops smaller than 0.5 mm diameter near the cloud base, where the falling raindrops rapidly grow by collision‐coalescence without breaking. The number concentration in the stratiform rain is relatively moderate; hence a gradual raindrop growth, and uniform vertical reflectivity. However, few raindrops in stratiform rain grow to a larger diameter than in convective rain, for the same rain rate due to the absence of collisional breakup.
Magnetotactic Bacterial Activity in the North Pacific Ocean and Its Relationship to Asian Dust Inputs and Primary Productivity Since 8.0 Ma

AbstractMagnetotactic bacteria (MTB) require iron and organic carbon for biomineralization, which can be supplied by dust inputs that stimulate primary productivity in iron‐limited oceans. However, MTB activity and its relationship to Asian dust inputs and primary productivity are not well known in the North Pacific Ocean. Here, we present an eight‐million‐year record of magnetofossil abundance, Asian dust flux, and primary productivity from North Pacific sediments (Ocean Drilling Program Hole 885A). Our results demonstrate that Asian dust delivered iron to stimulate primary productivity and then boost MTB biomineralization in the late Miocene. Since the late Pliocene, dust inputs and primary productivity appear to have been decoupled, with MTB activity controlled mainly by primary productivity rather than dust inputs. Equant magnetofossil abundances co‐vary with eolian flux, and may provide here a proxy for dust inputs. This work provides perspectives on relationship between MTB activity, dust inputs, and primary productivity on million‐year timescales.

AbstractDam removals are on the increase across the US with Pennsylvania currently leading the nation. While most dam removals are driven by aquatic habitat and public safety considerations, we know little about how dam removals impact water quality and riparian zone processes. Dam removals decrease the stream base level, which results in dewatering of the riparian zone. We hypothesized that this dewatering of the riparian zone would increase nitrification and decrease denitrification, and thus result in nitrogen (N) leakage from riparian zones. This hypothesis was tested for a 1.5 m high milldam removal. Stream, soil water, and groundwater N concentrations were monitored over 2 years. Soil N concentrations and process rates and δ15N values were also determined. Denitrification rates and soil δ15N values in riparian sediments decreased supporting our hypothesis but no significant changes in nitrification were observed. While surficial soil water nitrate‐N concentrations were high (median 4.5 mg N L−1), riparian groundwater nitrate‐N values were low (median 0.09 mg N L−1), indicating that nitrate‐N leakage was minimal. We attribute the low groundwater nitrate‐N to denitrification losses at the lower, more dynamic, groundwater interface and/or dissimilatory nitrate reduction to ammonium (DNRA). Stream water nitrate‐N concentrations were high (median 7.6 mg N L−1) and contrary to our dam‐removal hypothesis displayed a watershed‐wide decline that was attributed to regional hydrologic changes. This study provided important first insights on how dam removals could affect N cycle processes in riparian zones and its implications for water quality and watershed management.
