The management of “quality”: class decomposition and racial formation in a Chicago factory

Workplace training offers a distinctly explicit and uniquely articulate site for the ethnography of the capital–labor relation as an ideological phenomenon, where the everyday work of hegemony is shown to be deeply grounded in the everyday hegemony of work. In this ethnographic account of a factory classroom devoted to introducing production workers to the precepts of Total Quality Management and training them in Statistical Process Control, the neoliberal reform of the labor process—which sought to accomplish a class decomposition of the company’s workforce in favor of an individualizing regime of workers’ personal responsibility and accountability for various quality control operations—repeatedly provoked the company’s Latino workers into angry and vociferous expressions of antagonism to management. Indeed, insofar as the management’s efforts to reform labor by decomposing the workforce as a class formation merely intensified the prevailing preconditions of their racial formation, they thereby only exacerbated anew the Latino workers’ antagonism as workers to the terms of their subordination. Thus, the generic (ostensibly race-neutral) reform of the labor process initiated under the aegis of “Total Quality Management” implicated the presumed management of “quality” in a concomitant reconfiguration of what was, effectively, a contemporary regime of racial management.     

The Cultural Epigenesis of Gender-Based Violence in Cambodia: Local and Buddhist Perspectives

Almost one in four women in Cambodia is a victim of physical, emotional or sexual violence. The study aims to provide a comprehensive understanding of the ways in which Cambodians see its causes and effects and to identify and analyse the cultural forces that underpin and shape its landscape. An ethnographic study was carried out with 102 perpetrators and survivors of emotional, physical and sexual violence against women and 228 key informants from the Buddhist and healing sectors. Their views and experiences of it were recorded—the popular idioms expressed and the symptoms of distress experienced by survivors and perpetrators. From these results, the eight cultural forces, or cultural attractors, that are seen to propel a person to violence were identified. Violence stemmed from blighted endowment, or ‘bad building’ (sɑmnaa? m?n l?ɑɑ) determined by deeds in a previous life (kam). Children with a vicious character (kmee? kaac or do?a-carita) might grow to be abusers, and particular birthmarks on boys were thought to be portents. Kr??h, or mishap, especially when a female’s horoscope predicted a zodiac house on the descent (ries?y), explained vulnerability to violence and its timing. Astrological incompatibility (kuu kam) was a risk factor. Lust, anger and ignorance, the ‘Triple Poison’, fuelled it. ‘Entering the road to ruin’ (apāyamuk), including alcohol abuse, womanising and gambling, triggered it. Confusion and loss of judgement (mohā) led to moral blindness (mo ba?). These were the eight cultural attractors that shaped the landscape of violence against women. The cultural epigenesis of violence against women in Cambodia is an insight which can be used to build culturally responsive interventions and strengthen the primary prevention of violence against women. An understanding of the epigenesis of violence could strengthen the primary prevention of violence against women.     

Interactions Between the Circadian Clock and Heme Oxygenase in the Retina of <Emphasis Type="Italic">Drosophila melanogaster</Emphasis>

The Drosophila retina has an autonomous peripheral circadian clock in which the expression of the gene encoding heme oxygenase (HO) is under circadian control with the ho mRNA peaking at the beginning of the day and in the middle of the night. The function of HO in the retina is unknown, but we observed that it regulates the circadian clock and protects photoreceptors against DNA damage. The decline in HO level increases and decreases the expression of the canonical clock genes period (per) and Clock (Clk), respectively. The opposite result was observed after increasing HO expression. Among three products of HO activity—carbon monoxide (CO), ferrous ions, and biliverdin—the latter has no effect on per and Clk expressions, but CO exerts the same effect as the increase of ho expression. This suggests that HO action on the clock is mediated by CO, which may affect Clk expression during the day and the level of per expression. While ho expression is not stimulated by nitric oxide (NO), NO has the same effect on the clock as HO, increasing Clk expression and decreasing the expression of per.     

Anthropology and the social factory

Since its birth in the early 1960s, Italian operaismo (workerism) has provided an optimistic reading of working-class militancy, a theoretically stimulating account of capitalist transformation, and a set of highly productive conceptual categories. Despite a shared provenance, however, operaista-influenced movements and theorists have since taken these categories in quite varied directions. Given this conceptual heterogeneity, I consider herein one such category—the “social factory”—and its conceptual reworking by Antonio Negri, as he elaborates in his 2017 book, Marx and Foucault. I employ, as means to pursue this inquiry, an anthropological lens—drawing, to do so, on anthropological theory and ethnographic research. My aim is to build toward to a reconception of the social factory analytic for use in a contemporary anthropology of state formation.     

Selection of optimal flocculant for effective harvesting of the fucoxanthin-rich marine microalga <Emphasis Type="Italic">Isochrysis galbana</Emphasis>

Flocculation harvesting of the fucoxanthin-rich marine microalga Isochrysis galbana has received little attention. Therefore, we attempted to screen for an optimal chemical flocculant and optimize flocculation conditions from five chemical flocculants—ferric chloride (FC), aluminum sulfate (AS), polyaluminum chloride (PAC), aluminum potassium sulfate (APS), and zinc sulfate (ZS)—for effective flocculation of I. galbana. The growth rate, photosynthetic performance, and fucoxanthin content were determined in re-suspended flocculated algal cells and in the flocculation supernatant cultured algal cells. The results showed that high growth rate and fucoxanthin accumulation were observed when FC was used as the flocculant in I. galbana cultures, which indicated that FC may cause less harm to I. galbana than the other aluminum-based flocculants. Furthermore, satisfactory flocculation efficiency was also observed when FC was used to flocculate I. galbana, and the FC dosage was less than that required for flocculation of I. galbana using PAC, APS, and AS. Thus, we selected FC as the optimal flocculant for harvesting I. galbana based on its flocculation efficiency together with algal physiological performance, growth rate, and fucoxanthin content.     

A case for resurrecting lost species—review essay of Beth Shapiro’s, “How to Clone a Mammoth: The Science of De-extinction”

The title of Beth Shapiro’s ‘How to Clone a Mammoth’ contains an implicature: it suggests that it is indeed possible to clone a mammoth, to bring extinct species back from the dead. But in fact Shapiro both denies this is possible, and denies there would be good reason to do it even if it were possible. The de-extinct ‘mammoths’ she speaks of are merely ecological proxies for mammoths—elephants re-engineered for cold-tolerance by the addition to their genomes of a few mammoth genes. Shapiro’s denial that genuine species de-extinction is possible is based on her assumption that resurrected organisms would need to be perfectly indistinguishable from the creatures that died out. In this article I use the example of an extinct New Zealand wattlebird, the huia, to argue—contra Shapiro—that there are compelling reasons to resurrect certain species if it can be done. I then argue—again, contra Shapiro—that synthetically created organisms needn’t be perfectly indistinguishable from their genetic forebears in order for species de-extinction to be successful.     

Transformation in <Emphasis Type="Italic">Dang</Emphasis>-<Emphasis Type="Italic">ki</Emphasis> Healing: The Embodied Self and Perceived Legitimacy

Since spirit possession in mediumship and shamanism resembles psychotic symptoms, early researchers perceived spirit mediums and shamans as psychiatric patients whose psychopathology was culturally sanctioned. However, other researchers have not only challenged this assumption, but also proposed that spirit possession has transformative benefits. The idiom of spirit possession provides cultural meanings for spirit mediums and shamans to express and transform their personal experiences. The present case study focuses on dang-ki healing, a form of Chinese mediumship practiced in Singapore, in which a deity possesses a human (i.e., dang-ki) to offer aid to supplicants. This study seeks to explore whether involvement in dang-ki healing is transformative; and if so, how the dang-ki’s transformation is related to his self and the perceived legitimacy of his mediumship. At a shrine, I interviewed 20 participants, including a male dang-ki, 10 temple assistants, and nine clients. The results obtained were supportive of the therapeutic nature of spirit possession. First, there is a relationship between his self-transformation and the perceived legitimacy of his mediumship. As his clients and community have recognized his spirit possession as genuine, and the healing power of his possessing god, he is able to make use of mediumship as a means for spiritual development. Second, he has developed his spirituality by internalizing his god’s positive traits (e.g., compassion). Deities worshipped in dang-ki healing can be conceptualized as ideal selves who represent a wide range of positive traits and moral values of Chinese culture. Thus, the possession of a deity is the embodiment of an ideal self. Finally, the dang-ki’s transformation may run parallel to his god’s transformation. In Chinese religions, gods have to constantly develop their spirituality even though they are already gods. An understanding of the god’s spiritual development further sheds light on the dang-ki’s self-transformation.     

The State of Ethnoprimatology: Its Use and Potential in Today’s Primate Research

The human–primate interface is an increasingly relevant theme in primatological research. To understand the extent of ethoprimatological studies in contemporary primatology, we explored 7 years of primatological literature through a systematic review. We reviewed original research papers published in the American Journal of Primatology, the International Journal of Primatology, Primates, and Folia Primatologica between January 2010 and December 2016 for the presence of 14 search terms relevant to the ethnoprimatological approach. We sorted research papers into topical categories to identify trends in the recent primatological literature. Of the 1551 papers that met the criteria for inclusion in this review, 12 papers (0.8%) self-identified as an ethnoprimatological study by using the term in the title or keywords, and only 17 papers (1.1%) used the term anywhere in their text. However, the presence of other relevant keywords—anthropogenic (16.3%), crop (9.1%), disturbance (18.7%), conflict (6.2%), human–nonhuman (0.5%), human–primate (1.0%), interface (1.5%), perception (2.5%), culture (2.6%), ethnography (0.1%), trade (6.8%), provision (16.1%), and tourism (4.6%)—in a variety of research papers suggests that the human–primate dimension is salient for many, if not most, areas of primatological interest. The ethnoprimatological approach is relevant to every research trend we identified in today’s primatology. We highlight existing literature that exemplifies ethnoprimatological engagement and present potential research questions in each area, demonstrating that primatology as a whole would benefit from greater attention to the human dimension.     

New insight into the species diversity and life cycles of rust fungi (Pucciniales) affecting bioenergy switchgrass (<Emphasis Type="Italic">Panicum virgatum</Emphasis>) in the Eastern and Central United States

Research was undertaken to clarify the taxonomic identity of leaf rust (Pucciniales) fungi on bioenergy switchgrass in the Eastern and Central U.S. We integrated internal transcribed spacer 2 (ITS2) and partial 28S ribosomal RNA gene sequence data from collections taken from cultivated switchgrass and herbarium specimens, including purported aecial and telial states of Puccinia graminicola and Puccinia pammelii. Maximum likelihood and Bayesian analyses revealed four monophyletic clades: Puccinia emaculata sensu stricto (s.s.), P. pammelii, P. graminicola, and Puccinia novopanici. Results also indicated that P. emaculata s.s. was not affecting cultivated, bioenergy switchgrass. Aecidium pammelii and P. pammelii were distinct phylogenetically from P. emaculata s.s. and grouped within a well-supported clade, demonstrating aecial-telial host alternation for P. pammelii between Euphorbia corollata and switchgrass. Aecidium stillingiae on queen’s delight (Stillingia sylvatica)—a purported aecial state host for P. graminicola—shared identical sequences with the recently described species Puccinia pascua. The latter fungus, however, was recovered within a subclade of P. graminicola. Hence, queen’s delight likely is not an aecial host to P. graminicola s.s. Additional molecular studies are warranted to determine species boundaries within the P. graminicola complex. The majority of contemporary collections from cultivated switchgrass were recognized as P. novopanici. Collectively, bioenergy switchgrass is host to at least three phylogenetically distinct species, presenting a significant challenge to the future selection and breeding of switchgrass with improved rust resistance.     

Methylation of the genes for the microRNAs miR-129-2 and miR-9-1, changes in their expression,and activation of their potential target genes in clear cell renal cell carcinoma

Methylation of promoter CpG islands and microRNA (miRNA) interactions with mRNAs of target genes are epigenetic mechanisms that play a crucial role in deregulation of gene expression and signaling pathways in tumors. Altered expression of six chromosome 3p genes (RARB(2), SEMA3B, RHOA, GPX1, NKIRAS1, and CHL1) and two miRNA genes (MIR-129-2 and MIR-9-1) was observed in primary clear cell renal cell carcinomas (ccRCCs, 31–48 samples) by RT-PCR and qPCR. Significant downregulation (p < 0.05, Fisher’s exact test) was observed for SEMA3B, NKIRAS1, and CHL1; and differential expression, for the other chromosome 3p and miRNA genes. Methylation-specific PCR with primers to RARB(2), SEMA3B, MIR-129-2, and MIR-9-1 showed that their methylation frequency was significantly (p < 0.05, Fisher’s exact test) elevated in the ccRCC samples. Significant correlations between promoter methylation and expression were confirmed for SEMA3B and observed for the first time for RARB(2), GPX1, and MIR-129-2 in ccRCC (Spearman’s correlation coefficient r _s ranging 0.31–0.60, p < 0.05). The MIR-129-2 and RARB(2) methylation frequencies significantly correlated with ccRCC progression. MIR-129-2 methylation correlated with upregulation of RARB(2), RHOA, NKIRAS1, and CHL1 (r _s ranging 0.35–0.53, p < 0.05). The findings implicate methylation in regulating RARB(2), SEMA3B, GPX1, and MIR-129-2 and indicate that miR-129-2 and methylation of its gene affect RARB(2), RHOA, NKIRAS1, and CHL1 expression.     

Different determinants of exercise capacity in HFpEF compared to HFrEF

Background

Quality of life is as important as survival in heart failure (HF) patients. Controversies exist with regards to echocardiographic determinants of exercise capacity in HF, particularly in patients with preserved ejection fraction (HFpEF). The aim of this study was to prospectively examine echocardiographic parameters that correlate and predict functional exercise capacity assessed by 6 min walk test (6-MWT) in patients with HFpEF.

Methods

In 111 HF patients (mean age 63?±?10 years, 47% female), an echo-Doppler study and a 6-MWT were performed in the same day. Patients were divided into two groups based on the 6-MWT distance (Group I: ≤ 300 m and Group II: >300 m).

Results

Group I were older (p?=?0.008), had higher prevalence of diabetes (p?=?0.027), higher baseline heart rate (p?=?0.004), larger left atrium - LA (p?=?0.001), longer LV filling time - FT (p?=?0.019), shorter isovolumic relaxation time (p?=?0.037), shorter pulmonary artery acceleration time - PA acceleration time (p?=?0.006), lower left atrial lateral wall myocardial velocity (a’) (p?=?0.018) and lower septal systolic myocardial velocity (s’) (p?=?0.023), compared with Group II.Patients with HF and reduced EF (HFrEF) had lower hemoglobin (p?=?0.007), higher baseline heart rate (p?=?0.005), higher NT-ProBNP (p?=?0.001), larger LA (p?=?0.004), lower septal s’, e’, a’ waves, and septal mitral annular plane systolic excursion (MAPSE), shorter PA acceleration time (p?<?0.001 for all), lower lateral MAPSE, higher E/A & E/e’, and shorter LVFT (p?=?0.001 for all), lower lateral e’ (p?=?0.009), s’ (p?=?0.006), right ventricular e’ and LA emptying fraction (p?=?0.012 for both), compared with HFpEF patients.In multivariate analysis, only LA diameter [2.676 (1.242–5.766), p?=?0.012], and diabetes [0.274 (0.084–0.898), p?=?0.033] independently predicted poor 6-MWT performance in the group as a whole. In HFrEF, age [1.073 (1.012–1.137), p?=?0.018] and LA diameter [3.685 (1.348–10.071), p?=?0.011], but in HFpEF, lateral s’ [0.295 (0.099–0.882), p?=?0.029], and hemoglobin level [0.497 (0.248–0.998), p?=?0.049] independently predicted poor 6-MWT performance.

Conclusions

In HF patients determinants of exercise capacity differ according to severity of overall LV systolic function, with left atrial enlargement in HFrEF and longitudinal systolic shortening in HFpEF as the the main determinants.

     

Impact of worker longevity and other endogenous factors on colony size in the fire ant, <Emphasis Type="Italic">Solenopsis invicta</Emphasis>

Central to the survival and reproduction of social insect queens is the size of colonies at maturity. The influence of exogenous factors such as predation, food abundance, and seasonal changes in temperature on colony size are well studied. Less well studied are endogenous life-history factors such as a queen’s fertility and lifespan, duration of worker development from egg to adult and worker lifespan. Endogenous factors regulating the rate of colony growth and colony size were simulated using the fire ant, Solenopsis invicta. Assuming ideal environmental conditions of no predation, abundant food and uniform temperature, the simulation showed unequivocally that colony size is determined by two endogenous factors: a queen’s egg-laying rate (R _q) and worker longevity (L _w) (Colony size = R _q × L _w). Thus, we are left with an unanswered question: if worker longevity contributes directly to colony size, why is the lifespan of workers so short—in most cases, a small fraction of a queen’s lifespan?     

Characterization of <Emphasis Type="Italic">VvPAL-like</Emphasis> promoter from grapevine using transgenic tobacco plants

A 2000-bp 5′-flanking region of VvPAL-like was isolated from ‘Summer Black’ grapevine by PCR amplification, named pVvPAL-like. To gain a better understanding of the expression and regulatory mechanism of VvPAL-like, a chimeric expression unit consisting of the β-glucuronidase (GUS) reporter gene under the control of a 2000-bp fragment of the VvPAL-like promoter was transformed into tobacco via Agrobacterium tumefaciens. Histochemical staining showed that the full-length promoter directs efficient expression of the reporter gene in cotyledons and hypocotyls, stigma, style, anthers, pollen, ovary, trichomes, and vascular bundles of transgenic plants. A series of 5′ progressive deletions of the promoter revealed the presence of a negative regulatory region (?424 to ?292) in the VvPAL-like promoter. Exposure of the transgenic tobacco plants to various abiotic stresses demonstrated that the full-length construct could be induced by light, copper (Cu), abscisic acid (ABA), indole-3-acetic (IAA), methyl jasmonate (MeJA) (N-1-naphthylphthalamic acid), ethylene, and drought. Furthermore, the ethylene-responsive region was found to be located in the ?1461/?930 fragment, while the element(s) for the MeJA-responsive expression may be present in the ?424/?292 region in the VvPAL-like promoter. These findings will help us to better understand the molecular mechanisms by which VvPAL-like participates in biosynthesis of flavonoids and stress responses.     

An ATP-Binding Cassette Transporter Gene from <Emphasis Type="Italic">Cucumis sativus</Emphasis> L., <Emphasis Type="Italic">CsABC19</Emphasis>, Is Involved in Propamocarb Stress in <Emphasis Type="Italic">Arabidopsis thaliana</Emphasis>

A propamocarb-responsive gene named CsABC19 was isolated from a cucumber cultivar ‘D0351’ using a homologous cloning strategy. The full-length cDNA of CsABC19 was 921 bp with a complete ORF encoding 306 amino acids. Quantitative real-time PCR analysis revealed that CsABC19 was induced in the root, stem, leaf, and fruit by propamocarb and the expression levels of CsABC19 seemed to be different in different tissues. Further functional analysis showed that CsABC19 transgenic Arabidopsis plants appeared better growth performance under propamocarb stress and lower propamocarb residues. Our findings suggest that CsABC19 plays a crucial role in plant responses to propamocarb stress and also provide new clues for the mechanism regulation of the responses to propamocarb stress in cucumber.
