Observations of parturition among captive patas monkeys (Erythrocebus patas)

Six cases of labor and delivery by laboratory-housed patas monkeys (Erythrocebus patas) are described. Five of the births occurred during the daytime, and the sixth occurred just after the usual “lights out” time. Although it was impossible to determine the actual onset of labor, the final 1.5–0.5 hr before parturition were observed in all cases. Throughout labor, females tended to begin a contraction every 2–4 min and contractions usually lasted 35–60 sec. Females did not show common patterns of change in contraction frequency or duration as birth neared. It was not possible to describe patas monkey labor and delivery in terms of “stages.” Postpartum, females typically began cleaning their infants within 90 sec and picked them up within 5 min. Placental delivery times varied among females, as did the extent of placental consumption. One “mother-only” - reared female proved to be an inadequate mother.     

Idling in Mao’s Shadow: Heroin Addiction and the Contested Therapeutic Value of Socialist Traditions of Laboring

The Chinese government has come under attack by international critics for forcing drug users to labor in the name of treatment. While joining these activists in criticizing conditions in compulsory labor centers, former detainees who congregated at a drop-in center in southern Yunnan also defended the therapeutic potential of socialist legacies of laboring. Shuttling between laboring in state compulsory centers and idling in a market economy, long-term heroin users saw their difficulties in recovering from addiction as inextricably linked to their inability to find suitable work opportunities. Certain drop-in center attendees maintained that earlier Communist laboring projects had helped wayward citizens, including drug addicts, “merge into” society as productive workers. This group evoked the stable long-term jobs and benefits once provided by local state-owned enterprises and the radical revolutionary power of “remolding through labor” they imagined to have existed in the first years of the People’s Republic as powerful alternatives to their recent crisis of idling. The nuanced ways that drop-in center regulars revisited the potential healing power of earlier traditions of socialist laboring as remedies to their contemporary struggles complicates long-standing debates about coercion in treatment and the responsibility of the postsocialist state towards marginalized workers.     

Early hominid hunting and scavenging: A zooarcheological review

Before the early 1980s, the prevailing orthodoxy in paleoanthropology considered Early Stone Age archeological sites in East Africa to represent a primitive form of hominid campsites. The faunal evidence preserved in these sites was viewed as the refuse of carcass meals provided by hominid males in a social system presumptively characterized by sexual division of labor. This interpretation of early hominid life ways, commonly known as the “Home Base” or “Food Sharing” model, was developed most fully by Glynn Isaac.^1–4 As Bunn and Stanford⁵ emphasized, this model was greatly influenced by a paradigm that coalesced between 1966 and 1968, referred to as “Man the Hunter.”⁶     

Day labor halls as spaces of containment and control

Temporary day labor agencies (commonly referred to as “day labor halls”) are privately run companies external to the formal Prison Re-Entry Industry (PRI). However, they frequently provide entry-level employment for recent, frequent, and reformed felons. All spaces associated with day labor employment are rigidly controlled and caught in a visual contradiction. While laborers are completely visible to the day labor halls for the purposes of surveillance, observation, evaluation, and ultimately control, they are simultaneously rendered invisible and hidden from the view of society at large. For day laborers with felony records, the duality is intensified. Once released from prison, former prisoners enter spaces under the view and control of law enforcement within the formal PRI system. Further, their world continues to be viewed, restricted, and controlled by privately owned day labor halls where over 50% of potential workers are felons. By examining the spatialities of the daily working lives of day laborers and their (im)mobility as they navigate difficult spatialities, it is possible to comprehend some of the major hurdles of re-entry. The spatialities of the everyday life of felons continue as restricted spaces for a “captive population” even beyond the prison walls and beyond the formal systems of the PRI.     

Riding the perennial gale: working-class Puerto Ricans and the involution of colonial capitalism

Hurricane María devastated Puerto Rico in September 2017, deepening an already dire economic situation and amplifying an ongoing wave of out-migration. In the age of permanent man-made climate change, hurricanes, like extended economic crises, are “big events” produced by the capitalist despoiling of nature and labor, further exposing the dispossessed and displaced to structural violence. A colony of the USA since 1898, perhaps Puerto Rico has now once again “changed forever,” as the popular belief goes in the wake of María. If so, these changes will continually be experienced and enacted differently by subjects unevenly positioned in terms of unequal relationships of power and privilege. I propose an empirically informed research orientation that examines the situation of contemporary working-class Puerto Ricans in terms of their strategic responses to the involution of colonial capitalism. As a dimension of social life, working-classness is not contracting but expanding, in the context of an ongoing “debt crisis” better understood in terms of the self-consumption, or involution, of the modality of colonial capitalism established in Puerto Rico in the 1940s. In this light, strategic actions of working-class Puerto Ricans such as migration, informal labor, and subsistence/domestic production are not evidence of alternate modes of being, but part of the very conditions of working-classness today. I conclude by briefly identifying three areas for future research to flesh out the proposed orientation, focusing in the immediate term on responses to María by working-class communities in the island and the diaspora, in interaction with local and US elites.     

Multivariate assessments of activity-related skeletal changes: Interpreting Bell Beaker specialized male archery and social organization in Central Europe

Objectives

The Bell Beaker period witnessed the rise of individual inhumations with “wealthy” burial contexts containing archery-related grave goods, leading archaeologists to label the individuals in these tombs as “archers.” This study looks to (1) compare the skeletons from male “archer” burials with those from male “non-archer” burials—those not having archery-related grave goods—in order to assess a possible link between burial context and physical activity, and (2) apply a biomechanics profile to evaluate whether the individuals associated with these “archer” burials practiced specialized archer activity.

Materials and Methods

The corpus (males only) included 46 “archers” and 40 “non-archers” from Bell Beaker individual inhumations. Osteological data included measurements, scores of entheseal changes, and a diagnosis of certain pathologies. Data analyses involved visual observations, hypothesis tests, dimension reduction, and MANOVA, with approaches aimed at exploring the treatment of data missingness.

Results

Measurement data revealed no differences between the two groups. Evaluations of entheseal changes found that “non-archers” had consistently more instances of bone surface modifications than “archers.” Individual assessments of specialized archer occupation identified 11 possible specialized archers.

Discussion

These findings indicate a possible labor differentiation represented through the presence of a probably prestigious “archer” burial context. This suggests a link between grave good presence and labor, but not between a Bell Beaker archery occupation and an “archer” burial context. Data analyses support the application of biomechanics to osteological analyses in order to assess specialized activity on the skeleton.     

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.     

An analytical framework for social life cycle impact assessment—part 2: case study of labor impacts in an IC packaging company

Purpose

The pressure on brand firms in the electronics industry to improve the labor conditions of their workers in their global production networks is increasing. Given the significance of mitigating the impacts of production on labor, this study used the new development method of social life cycle impact assessment (SLCIA) for conducting labor impact assessment. An illustrative example in an integrated circuit (IC) packaging company is presented to demonstrate the assessment of the impacts and the identification of the potential for improvement of labor practices among three factories.

Methods

SLCIA method was proposed based on the UNEP/SETAC Guidelines that were reviewed in our previous work, Part 1 (in a previous article): Methodology. The proposed method was used to assess the impacts of operations on labor in the three factories of an IC packaging company. Nineteen indicators of labor–stakeholders were used to collect data from factories and organizations in 2012. The obtained values from these three factories were translated into social impact scores that ranged from 1 to 5. The score of each indicator was multiplied by the weights of each indicator, and a final score of labor situations was generated to identify the hotspots of labor impacts and to identify the factory with better labor performance.

Results and discussion

The main goal of this study is to demonstrate the effectiveness of our proposed SLCIA method in assessing the labor impacts in the electronics industry. Among three factories of IC packaging, factory C was ranked as having the lowest social impact on labor with a higher performance, followed by factories B and A. In addition, the results show that four indicators, “lacking labor union,” “did not hire a sufficient number of disabled employees,” “overtime work that exceeded the legal limit,” and “excessive number of dispatched workers,” were recognized as the main social impacts on labor in IC packaging production.

Conclusions

The SLCA technique was used to assess the impacts of the production processes of three IC packaging factories on the labor conditions of their factory workers. The proposed method shed light on the significant impacts of such processes. The proposed model demonstrated its potential advantage by systematically and effectively identifying the labor impact hotspots, which could assist managers in devising strategies that could improve the labor situations within their organizations.

     

Logical-Semantic Analysis and the Development of L.S. Vygotsky's Ideas About “Units” and “Elements” of Psychological Systems

Based on an analysis of L.S. Vygotsky's concepts of “units” and “elements” of psychological systems, this article highlights five of their attributes. It shows that these attributes are logically symmetrical, since in their wording they can be converted into one another by negation or by replacing some words with their opposites. This suggests that the concepts of the “unit” and “element” of a system are different poles of one theoretical construct of the activity of human psychology. Thus methods for the study of psychological systems by breaking them down into elements or by separating them into units can be seen as complementary. The article describes differences among the concepts of “unit,” “minimal unit,” and “cell” of a psychological system. It reviews several problems that are solvable using the “method of units,” as well as some concepts of the theory of psychological systems that are understood as holistic, conceptual, and active processes and/or results of human interaction with the world. Among the examples of such systems are “systems of psychological functions” (according to Vygotsky), as well as separate activities (according to A.N. Leontiev), human actions and operations (interactions with the world on the level of objects and mental or physical means). The “component” of a psychological system is defined as any “something” that in some sense belongs to or is included in human interaction with the world. A component that belongs to the system is called an “element” of it, but a component that is included in the functioning and development of the system is called a “part” of it. The article presents the mathematical and psychological foundation of these definitions. It identifies and discusses the substantial (independently existing) components of psychological systems and their attributes (properties and conditions). It describes the relationships between them using the bipolar theoretical constructs “part-element” and “substantial-attributive” component of a system.     

Toward a Marxian anthropology? Bare,abstract, mobile,global

Anthropology has conventionally taken as some of its most cherished foundational categories the precise opposites of the key concepts that animate this inquiry: rather than “bare life,” anthropology has tended always to emphasize the fullness and complexity of social and political life; instead of labor in the abstract, which we recognize in its commodified form as “labor-power,” anthropology has produced exquisite inventories of concrete laboring activities and the “cultural” content of productive work; against the impermanence and mutability of lives characterized by their mobility, the ethnographic enterprise has been deeply attached to the sedentarist presuppositions of lasting settlement, dwelling, and “community”; and contrary to the task of apprehending space on a global scale, ethnographic study has been overwhelmingly localized and place-bound. Rethinking these elementary premises of the ethnographic endeavor and situating these critical concepts at the center of our epistemological frameworks are crucial theoretical and practical tasks for any meaningful social inquiry today. In this regard, the Marxian theoretical arsenal is simply indispensable. But, in the derisive words of so many disciplinary forebears and overseers, is this properly “anthropological”? The prospective convergence of genuinely critical sociopolitical inquiry with the techniques and insights of anthropology must remain for us the locus of an urgent problem—an open question on an open horizon.     

Dufour’s gland secretion,sterility and foraging behavior: Correlated behavior traits in bumblebee workers

Bombus terrestris colonies go through two major phases: the “pre-competition phase” in which the queen is the sole reproducer and aggression is rare, and the “competition phase” in which workers aggressively compete over reproduction. Conflicts over reproduction are partially regulated by a group of octyl esters that are produced in Dufour’s gland of reproductively subordinate workers and protect them from being aggressed. However, workers possess octyl esters even before overt aggression occurs, raising the question of why produce the ester-signal before it is functionally necessary?In most insect societies, foragers show reduced aggression and low dominance rank. We hypothesize that ester production in B. terrestris is not only correlated with sterility but also with foraging, signaling cooperative behavior by subordinate workers. Such a signal helps to maintain social organization, reduce the cost of fights between reproductives and helpers, and increase colony productivity, enabling subordinates to gain greater inclusive fitness. We demonstrate that foragers produce larger amounts of esters compared to non-foragers, and that their amounts positively correlate with foraging efforts. We further suggest that task performance, potential fecundity, and aggression are interlinked, and that worker–worker interactions are involved in regulating foraging behavior.B. terrestris, being an intermediate phase between primitive and derived eusocial insects, provides an excellent model for understanding the evolution of early phases of eusociality. Our results, combined with those in primitively eusocial wasps, suggest that at early stages of social evolution, reproduction was regulated by a “primordial division of labor”, that comprised foragers and reproducers, which further evolved to a more complex division of labor, a hallmark of eusociality.     

Reimagining policy: Power,problems, and public stories

The authors of various practitioner and scholarly documents suggest markedly contrasting understandings about the nature of “policy.” These divergent conceptions raise the question: What is at stake by understanding the nature of policy in one way as opposed to another? The purpose of this philosophical inquiry is to interrogate the nature of “policy” as it relates to music education and to question the values that do and might underlie and propagate through contrasting understandings of “policy.” Subsequently, I examine two aspects of policy, problem identification and meaning-making, that have gone largely unexplored in the arts education literature.

Using Foucault's writings, I argue that power-laden policy texts often have the greatest impact, not when they are mandated, but when they go misrecognized as common sense. I also advocate for the consistent use of the terms “policy texts” and “policy actions,” including as an alternative to the imbalanced designations of “soft policies” and “hard policies.” Drawing on Dewey arts educators might form “publics” around problems having consequences that they deem far-reaching, recurrent, and irreparable. Individual and collective political narratives, including what Ganz explains as “stories of self,” “stories of us,” and “stories of now,” can foster the meaningful connections necessary for forming “publics” who address pressing problems in arts education.     

On concept formation in systematics

In his “Grundzüge einer Theorie der phylogenetischen Systematik”, Hennig (1950 ) cited three philosophers: the leading empiricist Rudolf Carnap, the conventionalist Hugo Dingler, and the somewhat more obscure empiricist Theodor Ziehen. David Hull characterized Hennig's “Grundzüge” as one long argument against idealistic morphology. It will here be argued that Hennig attacked idealistic morphology (synonymous with “systematic” morphology) for its mode of concept formation. Building on Carnap and Ziehen, who both looked back on Ernst Cassirer, Hennig argued that the “generic”, “thing” or “class” concept of traditional nomothetic science must be replaced with Cassirer's “relation concept.” According to Hennig, such “emancipation” of systematics from the Aristotelian “species” concept would also allow transcendence from the distinction of idiographic from nomothetic sciences, thus preserving the unity of science. However, the establishment of relations in the construction of a system of order presupposes entities that can be, or are, related. Relations presuppose relata, which in modern systematics are best conceptualized (at least at the supraspecific level) not as Aristotelian classes, nor as individuals as was argued by Hennig and Ziehen, but as tokens of natural kinds. © The Willi Hennig Society 2006.     

Rethinking Causation for Data-intensive Biology: Constraints,Cancellations, and Quantized Organisms

Complex organisms thwart the simple rectilinear causality paradigm of “necessary and sufficient,” with its experimental strategy of “knock down and overexpress.” This Essay organizes the eccentricities of biology into four categories that call for new mathematical approaches; recaps for the biologist the philosopher's recent refinements to the causation concept and the mathematician's computational tools that handle some but not all of the biological eccentricities; and describes overlooked insights that make causal properties of physical hierarchies such as emergence and downward causation straightforward. Reviewing and extrapolating from similar situations in physics, it is suggested that new mathematical tools for causation analysis incorporating feedback, signal cancellation, nonlinear dependencies, physical hierarchies, and fixed constraints rather than instigative changes will reveal unconventional biological behaviors. These include “eigenisms,” organisms that are limited to quantized states; trajectories that steer a system such as an evolving species toward optimal states; and medical control via distributed “sheets” rather than single control points.     

Reconciling “stress” and “health” in physical anthropology: What can bioarchaeologists learn from the other subdisciplines?

The concepts of “stress” and “health” are foundational in physical anthropology as guidelines for interpreting human behavior and biocultural adaptation in the past and present. Though related, stress and health are not coterminous, and while the term “health” encompasses some aspects of “stress,” health refers to a more holistic condition beyond just physiological disruption, and is of considerable significance in contributing to anthropologists' understanding of humanity's lived experiences. Bioarchaeological interpretations of human health generally are made from datasets consisting of skeletal markers of stress, markers that result from (chronic) physiological disruption (e.g., porotic hyperostosis; linear enamel hypoplasia). Non-specific indicators of stress may measure episodes of stress and indicate that infection, disease, or nutritional deficiencies were present in a population, but in assessing these markers, bioarchaeologists are not measuring “health” in the same way as are human biologists, medical anthropologists, or primatologists. Rather than continue to diverge on separate (albeit parallel) trajectories, bioarchaeologists are advised to pursue interlinkages with other subfields within physical anthropology toward bridging “stress” and “health.” The papers in this special symposium set include bioarchaeologists, human biologists, molecular anthropologists, and primatologists whose research develops this link between the concepts of “stress” and “health,” encouraging new avenues for bioarchaeologists to consider and reconsider health in past human populations.

Mort ou persistance du darwinisme ? Regard d’un épistémologue

The article examines why evolutionary biologists have been haunted by the question whether they are “Darwinian” or “non-Darwinian” ever since Darwin's Origin of species. Modern criticisms addressed to Darwinism are classified into two categories: those concerning Darwin's hypothesis of “descent with modification” and those addressed to the hypothesis of natural selection. In both cases, although the particular models that Darwin proposed for these two hypotheses have been significantly revised and expanded, Darwin's general framework has constrained and canalized evolutionary research, in the sense that it has settled an array of possible theoretical choices. Gould's changing attitudes regarding Darwinism is taken as a striking illustration of this interpretation.     

Moralizing regulation: the implications of policing “good” versus “bad” immigrants

Recently, the US has dramatically expanded immigration enforcement. At the same time, some advocates have sought to support “good” immigrants. This paper considers how the resulting good/bad binaries affect undocumented immigrants. I examine a case study in Los Angeles, where policing intertwined with protection. Based on participant observation and interviews, I show that respondents believed state agents classified them either as “bad” criminals or “good”, immigrants. To the extent immigrants identified as “good”, they credited the US with offering them “freedom” and hoped for political inclusion. At the same time, in what I call moralizing regulation, they also performed “good” behaviour and distinguished themselves from those seen as “bad”. Some also tied “good” behaviour to femininity and “acting white”. At the extreme, they blamed other migrants for inviting state mistreatment. The effects were ambivalent: while immigrants appreciated US support, they also adopted and adapted to the state’s moral norms.     

Ethnographic Note on Nation: Narratives and Symbols of the Early Post-socialist Nationalism in Lithuania

In the late 1980s and early 1990s Lithuania experienced the nationalist upheaval, which epitomized in the break up from the Soviet Union in 1990. Narratives and symbols were constitutive of the nationalist movement. “Nation” — the master symbol of that time — was reproduced in relation to the symbols of “the West,” and “the East,” as well as through the different values implied in “the West” and “the East” symbolism. Nationalist narratives reconstructed history and memory, reevaluated the present of the “reborn” nation, and drew the paths for the transition. Symbols and narratives were significant in mobilizing popular opinion, creating models for identity and action, and expressing moral and legitimate stances. They were a primary mechanism by which ideologies and cultural stances were shaped and maintained during the nationalist upheaval. In early 1990s the “nation” was redefined in the context of the Western tradition which was essential in communicating with the European countries and distancing from the former Soviet Union.     

Deconstructing the long-standing a priori assumption that serial homology generally involves ancestral similarity followed by anatomical divergence

It has long been assumed that serial homologues are ancestrally similar—polysomerism resulting from a “duplication” or “repetition” of forms—and then often diverge—anisomerism, for example, as they become adapted to perform different tasks as is the case with the forelimb and hind limbs of humans. However, such an assumption, with crucial implications for comparative, evolutionary, and developmental biology, and for evolutionary developmental biology, has in general not really been tested by a broad analysis of the available empirical data. Perhaps not surprisingly, more recent anatomical comparisons, as well as molecular knowledge of how, for example, serial appendicular structures are patterned along with different anteroposterior regions of the body axis of bilateral animals, and how “homologous” patterning domains do not necessarily mark “homologous” morphological domains, are putting in question this paradigm. In fact, apart from showing that many so-called “serial homologues” might not be similar at all, recent works have shown that in at least some cases some “serial” structures are indeed more similar to each other in derived taxa than in phylogenetically more ancestral ones, as pointed out by authors such as Owen. In this article, we are taking a step back to question whether such assumptions are actually correct at all, in the first place. In particular, we review other cases of so-called “serial homologues” such as insect wings, arthropod walking appendages, Dipteran thoracic bristles, and the vertebrae, ribs, teeth, myomeres, feathers, and hairs of chordate animals. We show that: (a) there are almost never cases of true ancestral similarity; (b) in evolution, such structures—for example, vertebra—and/or their subparts—for example, “transverse processes”—many times display trends toward less similarity while in many others display trends toward more similarity, that is, one cannot say that there is a clear, overall trend to anisomerism.     

Between Europe and the Balkans: Mapping Slovenia and Croatia's “Return to Europe” in the 1990s

This essay traces the ongoing discursive processes through which two former Yugoslav states — Croatia and Slovenia — framed their so-called “exit from the Balkans” and “return to Europe” throughout the 1990s. Applying Maria Todorova's framework of “Balkanism” to these two cases, the essay examines how leaders sought recognition as belonging to Europe, or Central Europe, by defining their respective national identities in opposition to Balkan or Yugoslav ones. What distinguishes Balkanism from other critical traditions such as Orientalism is that the Balkans are located in a distinctively liminal position: at the same time part of Europe as well as its antithetical periphery, the “other” within. This in-between position can often lead to contradictory identity constructions, whereby an insistence on concretizing one's Europeanness coincides with a certain awareness that this European status is never ontologically secure. The essay concludes by considering ways in which the Balkans can be re-imagined, reassembling diverse fragments of Balkan identity into a site for positive engagement and critique.
