Dynamic regime of the mesopause—lower thermosphere at mid-latitudes of the northern hemisphere by radio meteor observations

The coherent pulse Meteor Automatic Radar System (MARS) based at Kharkov (49°30′N, 36°51′E) was used to measure zonal winds in the altitude range 80–105 km in the period from November 1986 to December 1990. It was found that, for the greater part of the year, the zonal prevailing wind component was in the eastward direction. The change from eastward to westward direction begins in the lower thermosphere in February–March, propagating downwards to the mesosphere, and it remains there until June–July. The structure of semidiurnal tides has general regularities at different sites. Annual variations in the monthly mean values of semidiurnal vertical wavelengths are practically the same, both in the northern and southern hemispheres. Wavelengths are more than 100 km in summer months, whereas they are less than 60 km in winter months.Studies of internal gravity wave (IGW) parameters in the height range of 80–105 km have shown that the internal gravity wave amplitude does not exceed 30 m/s, the vertical wavelength is in the range of 10–30 km, the horizontal wavelengths are 100–800 km and the horizontal phase velocities are in the range 20–160 m/s. The propagation and breaking of upward and downward IGW at heights of 80–100 km have been recorded.     

Rethinking the homonormative? Lesbian and Hispanic Pride events and the uneven geographies of commoditized identities

Scant academic attention has been paid to intersectional LGBT events. Miami Beach is home to a women’s circuit party called Aqua Girl and a Hispanic LGBT Pride called Celebrate Orgullo. This behind-the-scenes study on their planning challenges the invisibility of intersectional LGBTs as consumers and demonstrates that they can be targeted as a profitable niche market. I utilize the homonormativity critique as a framing. It describes the commercialization and mainstreaming of LGBT populations as potentially oppressive and normative. However, I challenge the a-spatial essentialisms that characterize the literature. For example, the naming of gay white men and gentrified gayborhoods as the homonormative subject/spaces/places ignores how others can make use of homonormativity elsewhere. For instance, the entrepreneurial, tourism-centered government of Miami Beach targeted both lesbians and Hispanic LGBTs for these events. The success and sponsorship of these events is due not only to the popularity of Miami Beach with tourists, and the large local Hispanic population, but also the scarcity of similar events elsewhere. These events have homonormative aspects but defy reductive labeling or accusation. Therefore, it is important to consider the relationality of local manifestations of homonormativity while avoiding the essentialism or dismissals of de facto ‘homonormative subjects, spaces, or events’.     

Am I going mad?: Adverse meditation events and the anthropology of ethics

There has been growing interest in meditation adversities amongst mindfulness communities in recent years. This article documents US meditator distress upon experiencing incoherence in the eclectic resources supporting their practice. How might the anthropology of ethics consider self-cultivation practices when the traditions supporting them fail due to incoherence? We need further research on moral bricolage to answer that question.     

Landscapes at the Periphery of Glacierization – Retrospect and Prospect

This paper reviews the evolution of palaeoglaciological reconstructions in regions at the periphery of glacierization, where an improved understanding of the role of glacial thermal regime has helped refine the delimitation of ice sheet maxima. Also significant has been the recognition in numerical models that some areas, especially ice sheet marginal zones, are subject to short periods of ice occupancy and hence that glacial landsystem signatures can be extremely subtle. This is compounded wherever cold-based conditions dominate during early stages of ice sheet recession, giving rise to a landform imprint typical of peripheral regions and hence often misinterpreted as unglaciated or glaciated only by older glaciations. Subtle landform imprints include meltwater channels, thin glacigenic veneers or scattered erratics and modified tors. More substantial glacigenic landform-sediment assemblages (‘drift belts’) do not always represent ice sheet maxima but instead may record significant changes in thermal regime, possibly linked to periods of ice-marginal stabilization. Some upland areas that lie beyond the traditionally demarcated limits of glaciation (e.g. Dartmoor in SW England) may contain subtle evidence of satellite ice cap development which has been overlooked due to the strong periglacial landform signature.     

Liquefaction Resistance of Silty Sands and Dynamic Properties of Cohesive Soils from Düzce,Turkey

This article presents results from a laboratory investigation into the cyclic and dynamic properties of soils from Düzce, Turkey, conducted after the destructive November 12, 1999 earthquake. The investigation was mainly conducted by means of monotonic and cyclic triaxial, as well as resonant-column tests. The triaxial tests allowed the determination of the liquefaction resistance of silty sands, as well as their critical state behavior, whereas the resonant-column tests allowed the determination of shear modulus and damping ratio of cohesive soils. The results are presented and then discussed together with their pertinence to soil behavior when subjected to earthquake loading.     

Isaiah 1,4–9, Isaiah,and the events of 701 BCE in Judah

Abstract

The title of this paper points to the relationship between the Israelite cult as cultural performance and current trends in modern interpretation of the Psalms. The first part includes a review of the wellknown “spiritualisation” of cultic language which is compared to a new approach that describes this phenomenon as a “transformation” of cultic patterns. The second part intents to demonstrate how such transformations could have worked. The “liturgical” text of Ps 24 may serve as an eloquent example of this. Here, a fragment from the ancient temple cult is quoted in order to demonstrate the close connection between the secrets of the inner temple and everyday life. Ps 24 now appears to be an erudite text used for educational purposes.     

The collision of heritage and economy at Uxbenká, Belize

The relationship between the Mopan Maya community of Santa Cruz and the Classic period Maya site of Uxbenká in southern Belize has had a lasting impact on archaeological investigation and conservation at the site over the last generation. Community members, long the ‘stewards’ of Uxbenká, believe they have an economic right to the ruins that translates loosely into ‘ownership’. Although they seek to maintain the relationship between Santa Cruz and Uxbenká, archaeologists with the Uxbenká Archaeological Project (UAP) challenge the legitimacy of the community’s claim via the power vested in them by the state to conduct scholarly investigations at the site. For both the UAP and the state‐affiliated Institute of Archaeology, Uxbenká belongs not to one village but to all Belizeans. This paper is a data‐driven analysis of the interactions and expectations of community members, archaeologists, and the state as they interact within the archaeoscape of Uxbenká.     

Jean Améry's Concept of Resentment at the Crossroads of Ethics and Politics

The questions of forgiveness and political justice have recently become intertwined with the “transitional justice” project, the aim of which is the coming to terms with past human rights violations. This article demonstrates that “transitional justice” is less concerned with providing justice than with achieving historical closure, moral redemption, and a “new beginning.” It proposes that justice requires a profound reflection of a political nature by introducing and discussing Jean Améry's concept of resentment. Central to Améry's view of resentment is the restoration of the victim's social status and dignity, the validation of the experience of victimhood; his view therefore contrasts with the Nietzschean derogative view of ressentiment. On the basis of Améry's conceptualizations and with reference to Derrida's notions of “hiatus” and “forgiveness as impossibility,” the article problematizes the relation of ethics and politics—which the “transitional justice” project takes as given. It suggests that to theorize on justice, one needs to parenthesize the moral imagery of forgiveness and bring thirdness (or plurality) to the fore as the space where the identities of “victims” and “perpetrators” are established and played out.     

Consequences of conquest? The analysis and interpretation of subadult trauma at Puruchuco-Huaquerones, Peru

This paper examines bioarchaeological evidence of violence and traumatic injury on subadult skeletal remains from two Late Horizon (A.D. 1470-1540) cemeteries within the archaeological zone of Puruchuco-Huaquerones, Peru. Here we present the frequency and types of traumatic lesions on the 242 subadults analyzed. We observed significant increases in the frequency of subadult trauma, particularly among the burials associated with Spanish Conquest. Specifically, we noted a statistically significant increase in the frequency of cranial trauma in a subsample of individuals from one of two cemeteries at the site, 57AS03. These perimortem cranial injuries suggest an intensification of violence and lethality that may have affected the children from this community. We then discuss the biocultural implications of this analysis within the context of Spanish invasion and conquest.     

The Function and Iconography of the Minstrels’ Gallery at Exeter Cathedral

The Minstrels’ Gallery of Exeter cathedral has received attention in almost every major account of the church’s fabric, but has never been taken as a subject in its own right. This paper seeks to review and assess existing interpretations of the gallery’s construction and purpose, along with those of the nave’s north entrance with which the gallery’s history is inextricably linked. In addition to evaluating existing scholarship, this paper will also propose three further theses: first, that the gallery was inserted into a finished nave bay, probably in the 1350s or 1360s, which already contained a north porch built entirely by the mason Thomas of Witney on the foundations of its Romanesque predecessor; secondly, that its function was to offer an inexpensive alternative to the singing-gallery which was planned but not built in the image-screen on the cathedral’s west front; and, thirdly, that the role of the gallery and the north entrance to the nave in the Palm Sunday liturgy has influenced the iconography of the nave and gallery. This paper seeks to gather together the wealth of interest which the gallery has attracted over the last two centuries and to contribute to this exceptional history of scholarship.     

D’Arcy Thompson’s On Growth and Form and the Concept of Dynamic Form in Postwar Avant-Garde Art Theory

Abstract

The impact is considered of D’Arcy Thompson’s notion of biological form as set out in On Growth and Form on postwar avant-garde experimental art practices associated with the Independent Group, Nigel Henderson’s photography, and László Moholy-Nagy’s post-Bauhaus art theory. How Thompson’s insistence on the importance of physical forces in shaping biological form, and of distortion as a component of symmetrical systems, influenced the writings and practices of these artists, is explored, linking abstraction to legacies concerned with materiality and technique encountered earlier in Constructivism. Henderson’s photograms and ‘stressed photography’ are shown to be directly inspired by Thompson’s conception of form as a diagram of forces, and attest to a novel understanding of rules of symmetry in abstract form that may be seen in the dynamic processes at play in complex natural phenomena. How Moholy-Nagy explored these notions theoretically is examined, for example in his definition of drawing in Vision in Motion, which cites Thompson directly as a source of inspiration.     

Women helping women? Chain of command and gender discrimination at the workplace

ABSTRACT

We analyse the gender composition of the highest hierarchical levels within large Italian firms and we investigate whether it correlates to the working career of women in lower ranks of the same firm. We observe a disproportionate share of men hired and promoted, regardless of the top ranks’ gender composition. However, we detect a mitigating effect when the presence of women in higher managerial ranks increases promotions of women in lower ranks. This is consistent with the “women helping women hypothesis”. However, this mitigating effect is far from rebalancing career chances by gender. No significant differences emerge between firms in innovative and traditional sectors, despite the quite different narrative put in place by HR managers.     

What Happened at Curuguaty? The Coup and the Limits of Hegemonic Thought

The Paraguayan parliamentary coup against Fernando Lugo in 2012 fired the opening shot (following the CIA-induced removal of Honduras’s Manuel Zelaya in 2009) in the series of reversals of ‘pink tide’ politics throughout much of Latin America, most notably Brazil. But the Paraguayan case, argues art critic and former Minister of Culture Ticio Escobar, also has several particularities, such as the incapacity of Left and Right alike to construct enduring hegemonies after the collapse of the Stroessner dictatorship in 1989, as well as the increasingly potent shadow cast over the national political landscape by narco-capital. The still-unresolved massacre of peasant protesters at Curuguaty, which sparked Lugo’s overthrow only a week later, functions as an almost Brechtian theatricalization of these force-fields that have dominated Paraguay ever since the Triple Alliance War (1865–1870).     

Solar flux and seasonal variations of the mesopause temperatures at 51°N

Observations of the OH (8-3) band airglow emission, using a multichannel tilting filter type photometer, have been carried out at Calgary (51°N, 114°W), Canada, since 1981. In this paper recent measurements of the nocturnal, seasonal and solar flux variations of the mesopause temperature, obtained from the rotational temperature of the OH (8-3) band observations, are presented. The data presented span the ascending phase of the present solar cycle viz. 1987–1988 (low solar activity) and 1990 (high solar activity). Good correlations (r = 0.73) between the OH (8-3) band rotational temperature and the 10.7 cm solar flux were observed. The mean temperature for the period investigated was about 210 K. The seasonally averaged nocturnal variations show only small irregular excursions, possibly associated with solar tides and the passage of gravity waves in the mesopause region. However, the observed rotational temperatures show considerable night-to-night changes.     

States of difference: Refiguring ethnicity and its ‘crisis’ at India's borders

This article critically rethinks the possibilities and paradoxes of identity at the interstices of South Asia. Through ethnographic and historical analyses, I chronicle the varying forms, (dis)contents, and failures of ethnic identity in the geo-politically sensitive region of Darjeeling, India. In this Himalayan corner of the nation-state, borders have proven simultaneously generative yet undermining of identity and its politics—at once amplifying communities' desires for national inclusion, while rendering them largely unable to meet the Indian state's criteria for national recognition. As is the case along India's other borders, anxieties over national belonging have subsequently spawned violent subnationalist agitations in Darjeeling, as well as more legal quests for right, recognition, and autonomy. But to little avail. A perennial ‘identity crisis’ thus haunts (and charges) the people and politics of this Himalayan borderland. Refiguring the crisis at hand, this paper asks how certain forms of human difference become viable identities in India, while others do not. Doing so, I locate the crisis not within the realm of identity, but rather its rightful recognition. The paper accordingly develops ‘states of difference’ as an analytic for understanding the accentuated, paradoxical interplays of identity, state, and difference at the borders of South Asia and beyond.     

Peopling the Recent Past in the Serra de L’Altmirant: Shepherds and Farmers at the Margins

The region of the Serra de l’Altmirant in southeastern Spain, through its upland location and its rocky and scrub landscape, is strongly perceived as marginal–this mainly in contrast with the nearby fertile coastal plains between Valencia and Denia, busy with orange and vine production especially. A progressive colonization of the lower part of the Serra by weekend homes is starting to counter this image of marginality, but at the same time such constructions threaten the residual archaeology of a different type of human upland exploitation, namely pastoralism and hunting. Abandoned terraces, cisterns, store buildings and larger corrals are evident even on the exposed plateau and testify to a period in which the Serra was active and integral to farmers and shepherds from the villages of the adjoining valleys and plains. This paper discusses the nature of this activity, as recorded through archaeological and ethnographic investigation, and considers also the materials and outlook of Manolo, the last shepherd-in-residence on the Serra.
