Equivocal locations: being ‘red’ in ‘Red Bologna’

This article addresses a classic ethnographic problem in the study of Italy: how is it that people can subscribe simultaneously to seemingly contradictory ideologies, such as Catholicism and Communism? It does so by describing examples from Italy's ‘showcase city’ of the left, ‘Red Bologna’, in which to be ‘red’ is ubiquitous but each person's ‘red’ is a different thing: being ‘red’ (differently) is the idiom in which real political distinctions are expressed over issues like religion or immigration. In parallel, I discuss the relationship between the ‘field’ as a location and the ‘field’ as a conceptual topic. My account replicates internal ethnographic differences at the analytical level by highlighting the differences between being left‐wing in Bologna and its meaning as a concept in anthropology. Hence the ‘equivocal location’: a field‐site that is productively different, from what an inexperienced ethnographer expected from it, from conceptual discussions in anthropology, and from itself.     

Nations and Tribes ‘Within’: Emerging Aboriginal ‘Nationalisms’ in Katherine

Throughout Australia, many Aboriginal responses to the legislative and administrative pressures of the native title regime have been couched in a nation‐building idiom expressed through legally incorporated Aboriginal associations. The membership criteria of these umbrella associations are often derived from definitions of the ‘tribe’ or ‘language group’. Yet, in a kind of Balkanisation, those who see themselves as marginalised to positions of uncertainty on the peripheries of the nation often seek to establish their own independent corporations on the basis of exclusive ties to specific areas of land within it, in search of greater recognition and in competition for scarce resources. In Katherine, in the Northern Territory of Australia, the administrative and legislative gaze of the State, particularly the Aboriginal Land Rights (Northern Territory) Act 1976, brought into focus a Jawoyn ‘tribe’, soon to express itself in the idiom of nationhood, closely followed by a Wardaman ‘tribe’ and ‘nation’. More recently, a native title gaze has now brought into focus ‘new’ configurations of kindred clusters, apparently located on the ‘peripheries' of the Jawoyn and Wardaman nations, and named and valued them as Dagoman. This paper discusses the processes associated with an emerging, but seemingly already fragmenting, Dagoman nation. It argues that divergent and changing Aboriginal subjectivities disrupt what might be seen as mimetic processes as Aboriginal people employ strategies of transforming essentialist representations of their collective selves in changing conditions of possibility.     

‘I am helping them’: ‘Traffickers’, ‘anti‐traffickers’ and economies of bad faith

For several years, aid programs in the Mekong region have taken an increasing interest in cross‐border mobility and human trafficking and its relationship with development. More recently, there has been an increasing interest in the identification of trafficked victims and the investigation, arrest and prosecution of traffickers. Whereas anti‐trafficking programs ubiquitously define themselves as being in a battle with traffickers, this article argues that although they are not homologous social actors, both engage in acts of bad faith. The article elaborates this argument by drawing attention to the recruitment process within the Lao sex industry as well as to the way in which aid programs attempt to identify trafficked victims. It concludes that imaginary aspects of development underpin a simultaneous disjuncture yet enable the social reproduction of the life worlds of ‘traffickers’ and ‘anti‐traffickers’ alike.     

‘Dancing the image’: materiality and spirituality in Andean religious ‘images’

In the Christian tradition, representing the divine has often been considered both an impossible and yet necessary endeavour rooted in the human need in certain moments of weakness to visualize God. In this article, based on research findings from fieldwork carried out with urban indigenous groups in La Paz, Bolivia, I suggest that the articulation of local and Catholic representational traditions and practices has produced an understanding of the religious image not so much as an object of detached contemplation or a reference to a religious symbol but rather as an energized element which physically shapes the relationship and exchange between the material and the spiritual world. I suggest that through a study of Andean religious images we may be able to produce an alternative ontological perspective on the relationship between the spiritual, material, and living worlds.

Résumé

Dans la tradition chrétienne, la représentation du divin est souvent considérée comme une gageure impossible et pourtant nécessaire, motivée par la nécessité humaine de visualiser Dieu dans les moments de faiblesse. À partir des matériaux de terrain obtenus auprès de groupes autochtones urbains à La Paz, en Bolivie, l'auteur suggère ici que l'articulation des traditions et pratiques de représentation locales et catholiques a conduit à concevoir l'image religieuse moins comme un objet de contemplation détachée ou une référence à un symbole religieux que comme un élément chargé d'énergie, qui donne physiquement forme à la relation et aux échanges entre le monde matériel et le monde spirituel. L'article suggère qu'à travers l'étude des images religieuses andines, on pourrait élaborer un autre point de vue ontologique sur la relation entre les mondes spirituel, matériel et vivant.     

Mechanisms of phytohaemagglutinin (PHA) stimulation of normal human lymphocytes: ‘trigger’, ‘push’ or both?

Abstract. The growth in volume of human peripheral blood lymphocytes after stimulation with various concentrations of PHA was measured with an electronic particle counter. The percentage of growing cells and averaged values describing their growth rates during the elapsed period of culture were estimated by fitting to the observed data the volume distributions derived from a mathematical model. With sub-optimal doses, the percentage of cells stimulated, and their incremental growth rate, increased with increasing dose of PHA, but the time-course of recruitment into the G₁-phase was similar with all PHA concentrations studied. The results provide strong support for the 'trigger' hypothesis that there is a distribution of stimulation thresholds within the lymphocyte population: consequently, increasing mitogen concentration will be expected to result in increased numbers of responding cells within the suboptimal concentration range.     

A reply to the ‘critical evaluation of the Oscillayers methods and dataset’

Brown, Hill & Haywood (2020) offered a critical evaluation of the theory and methods of the Oscillayers approach and attempted to test its utility by reproducing global circulation model (GCM)‐based palaeoclimatic reconstructions of two variables (Bio1 and Bio12) for four different time points (130 ka, 787 ka, 3.2 Ma and 3.3 Ma). They concluded that Oscillayers show poor agreement with independent GCMs and thus do not provide a robust approximation of palaeoclimate throughout the Plio‐Pleistocene. Here, I demonstrate that the authors underestimated the ability of Oscillayers to reproduce independent GCMs by not taking into account inter‐framework differences between the models used to generate the Oscillayers and PaleoClim datasets. However, upon correcting this systematic error, differences in Bio1 and Bio12 between Oscillayers and PaleoClim GCMs are less than ± 1°C or ± 50 mm, on average, in 35.9% (range: 11.8–59.0%) or 46.7% (20.8–66.0%) of values, respectively. Thus, the agreement between Oscillayers and PaleoClim is, on average, c. 1.5–2 times higher than estimated by Brown et al. (2020) and mostly well above the inter‐model agreement between two commonly used GCMs (CCSM and MIROC) for the Last Glacial Maximum. Consequently, I conclude that the Oscillayers approach does provide reasonably robust approximations of palaeoclimate throughout the Plio‐Pleistocene. Some clarifications are given.     

The effects of ‘Step-down’ on RNA metabolism in HeLa cells

HeLa cells were subjected to ‘step-down’ conditions, and measurements were made of the high and low salt RNA polymerase activity, phosphorylation of uridine, incorporation of precursors into both RNA and protein and their respective acid-soluble pools, at different cell densities. It was found that ‘step-down’ conditions induced increased activity in both types of polymerase, decreased phosphorylation of uridine and reduced the incorporation of radioactive precursors into both the amino acid and nucleotide pools.     

Detection and Identification of ‘Candidatus Phytoplasma prunorum’, ‘Candidatus Phytoplasma mali’ and ‘Candidatus Phytoplasma pyri’ in Stone Fruit Trees in Poland

A survey was made to determine the incidence of phytoplasmas in 39 sweet and sour cherry, peach, nectarine, apricot and plum commercial and experimental orchards in seven growing regions of Poland. Nested polymerase chain reaction (PCR) using the phytoplasma‐universal primer pairs P1/P7 followed by R16F2n/R16R2 showed the presence of phytoplasmas in 29 of 435 tested stone fruit trees. The random fragment length polymorphism (RFLP) patterns obtained after digestion of the nested PCR products separately with RsaI, AluI and SspI endonucleases indicated that selected Prunus spp. trees were infected by phytoplasmas belonging to three different subgroups of the apple proliferation group (16SrX‐A, ‐B, ‐C). Nucleotide sequence analysis of 16S rDNA fragment amplified with primers R16F2n/R16R2 confirmed the PCR/Restriction Fragment Length Polymorphism (RFLP) results and revealed that phytoplasma infecting sweet cherry cv. Regina (Reg), sour cherry cv. Sokowka (Sok), apricots cv. Early Orange (EO) and AI/5, Japanese plum cv. Ozark Premier (OzPr) and peach cv. Redhaven (RedH) was closely related to isolate European stone fruit yellows‐G1 of the ‘Candidatus Phytoplasma prunorum’ (16SrX‐B). Sequence and phylogenetic analyses resulted in the highest similarity of the 16S rDNA fragment of phytoplasma from nectarine cv. Super Queen (SQ) with the parallel sequence of the strain AP15 of the ‘Candidatus Phytoplasma mali’ (16SrX‐A). The phytoplasma infecting sweet cherry cv. Kordia (Kord) was most similar to the PD1 strain of the ‘Candidatus Phytoplasma pyri’ (16SrX‐C). This is the first report of the occurrence of ‘Ca. P. prunorum’, ‘Ca. P. mali’ and ‘Ca. P. pyri’ in naturally infected stone fruit trees in Poland.     

‘Black’ and ‘white’ death: burials in a time of Ebola in Freetown,Sierra Leone

The article examines experiences of the 2014‐15 Ebola crisis in Freetown, Sierra Leone, through an analysis of the performance of burials. While most of the city's residents had no contact with the virus, ‘Ebola’ was inescapable, owing to the onerous state of emergency regulations imposed by national and international authorities. All burials, regardless of the cause of death, were to be performed by newly established official teams operating according to unfamiliar biomedical and bureaucratic protocols. Burials became emblematic of the crisis through presenting a conflict between local practices and novel procedures, which was coded locally in a complex racial language of ‘black’ and ‘white’, recalling a long regional history of violent integration into the Atlantic World. Building on long‐standing anthropological discussion on the relationship between ‘good’ death and social order, the article explores how burials became sites around which opposing ‘orders’ were experienced, negotiated, and reconciled in locally meaningful ways.     

A plea for ‘genealogical thinking’ in comparative biology – a rebuttal to the reply of Szucsich,Wirkner, and Pass to my article ‘Deconstructing Morphology’

Scholtz G. in press. A plea for ‘genealogical thinking’ in comparative biology – a rebuttal to the reply of Szucsich, Wirkner, and Pass to my article ‘Deconstructing Morphology’. —Acta Zoologica (Stockholm) 00 : 1–4. Szucsich et al. (in press) claim that – in contrast to my statement – morphological thinking has to be ‘cladistic.’ Based on this premise, they stress the difference between the relationships among states of characters versus those among structures assigned to the same character state as implemented in numerical cladistic reasoning. SEA claim that my approach to the homology concept only deals with the problem of the integration of various character states into the same character, whereas the necessary relationships among structures assigned to the same state are not covered. Based on this distinction, SEA also criticise the application of similarity in my definition of homology. Furthermore, they address the issue of evolutionarily independent units.     

Raman spectroscopy of serum: A study on ‘pre’ and ‘post’ breast adenocarcinoma resection in rat models

Risk of recurrence is a major problem in breast cancer management. Currently available prognostic markers have several disadvantages including low sensitivity and specificity, highlighting the need for new prognostic techniques. One of the candidate techniques is serum‐based Raman spectroscopy (RS). In this study, feasibility of using RS to distinguish ‘pre’ from ‘post’ breast tumor resection serum in rats was explored. Spectral analysis suggests change in proteins and amino acid profiles in ‘post’ compared to ‘pre‐surgical’ group. Principal‐Component‐Linear‐Discriminant‐Analysis shows 87% and 91% classification efficiency for ‘pre’ and ‘post‐surgical’ groups respectively. Thus, the study further supports efficacy of RS for theranostic applications.

     

Dynamic mechanical testing of human skin ‘in vivo’

The problems involved in measurement of the dynamic mechanical properties of human skin in vivo are examined. On the basis of these observations, the design of a rotary position servo for in vivo testing is outlined. Using this device, certain hitherto unidentified characteristics of the mechanical behaviour of human skin are illustrated.     

Cleaner Wrasses Keep Track of the ‘When’ and ‘What’ in a Foraging Task1

In recent years evidence has accumulated that at least some animals can remember the ‘what’, ‘where’ and ‘when’ of personal experiences. Currently, evidence for such ability is taxonomically restricted to birds and mammals. Here, we demonstrate for the first time that cleaner wrasses Labroides dimidiatus are able to remember when they interacted with what after a single event. In nature, cleaners remove ectoparasites from other reef fishes, so‐called clients. Clients are depleted, non‐stationary food patches at the end of an interaction and replenished only after a delay. In our experiments, we presented twelve cleaners every 2.5 min, a choice between two of a total of four plates with different colours and patterns. One plate was always accessible but contained a non‐preferred food item while the other three contained a preferred food item, but allowed a next feeding event only after 5, 10 or 15 min. Thus, to maximise food intake, cleaners had to remember for each choice when they had last interacted with which plate. When confronted with two plates offering preferred food, cleaners showed an overall significant preference for the plate that allowed access during the trial. For six cleaners, the preference was significant. Also, on trials involving the always accessible plate, cleaners discriminated between trials in which they had to eat the non‐preferred food and trials on which they could eat the preferred food. In conclusion, cleaners are able to track the ‘when’ and ‘what’ (or possibly ‘who’) within a biologically meaningful time period.
