‘’Tis Not in the Power of Words to Tell What My Heart Feels in Favour of You’; or,What the Ossulston Diary Does Not Reveal

Charles Bennet, 2nd Baron Ossulston is largely known through his diary of his daily social encounters, which was first analysed for its political import by Clyve Jones. A further set of documents in the Bennet family papers deepens our understanding of Ossulston's life and his social milieu among the aristocracy under Queen Anne. The love letters sent to him from a Mrs Sarah Sidney throughout 1710 reveal much about life in the aristocratic hothouse of St James's Square. They also show how the ‘ministerial revolution’ of that year was seen by two politically conversant figures at the margins of the royal court. This relationship was long-lasting and has been a hitherto unknown aspect of Ossulston's life, which may help explain some of his attitudes.     

Metastatic carcinoma in a 14th–19th century skeleton from Constância (Portugal)

During 2002, the extensive archaeological excavations of the ancient Constância necropolis (Centre of Portugal), dated from 14th–19th centuries, resulted in the exhumation of 151 individuals. Among the several paleopathological cases, a middle‐aged female skeleton with osteolytic lesions in her skull, axial skeleton, upper limbs and femurs was observed. These pathological findings are characterised by an asymmetric pattern with osteolytic focus of distinct size and irregular shape. Some skeletal elements display both osteolytic and osteoblastic lesions. The latter exhibit deposition of fine layers of woven bone. Lesions were observed macroscopically and radiology was used as a complementary method of scrutiny, especially in cases of unclear observation. The case was diagnosed as that of a probable metastatic carcinoma due to the multifocal distribution of the lesions in areas of intense haematopoietic activity, their morphology and some osteoblastic responses, as well as the presence of pathological fractures in the ribs. The skeleton's sex and age at death are in agreement with the proposed diagnostic, constituting the first case of malignant carcinoma detected in non‐identified Portuguese human skeletal remains.

The Design and Development of a Closed Chamber for the in‐situ Quantification of Dryland Soil Carbon Dioxide Fluxes

This paper describes the design features and capabilities of a portable automated in‐situ closed chamber (ISCC) for the quantification of CO₂ fluxes in dryland soils where both photosynthetic and respiratory components may be associated with a cyanobacterial crust. The processes of CO₂ flux in dryland soils are briefly described in order to clarify the conditions that make quantification of these fluxes problematic. The instrumentation currently available for in‐situ soil CO₂ flux measurements is then reviewed demonstrating their inadequacies for the dryland environment. The ISCC described here is a member of the closed or enrichment class of soil respiration chambers. The ISCC, however, features an optical window possessing high (>90%) transmission in the photosynthetic active region (PAR) of the solar irradiance spectrum, permitting observations of photosynthesis. The ISCC possesses automatic venting and purging so that gaseous concentrations inside the chamber do not change from ambient sufficiently to significantly affect diffusion. The ISCC features both active and passive cooling employing internal solid‐state Peltier coolers and external aluminised Mylar respectively. This avoids severe disturbance of the microclimate within the chamber due to admission of high fluxes of PAR and permits in‐situ operation under a wide range of ambient field temperatures (~ ?5 to 40°C). Sensors internal to the chamber monitor temperature, relative humidity, irradiance and pressure. In this implementation the ISCC is coupled to a portable gas chromatograph (Agilent GC‐3000) to sample the chamber atmosphere. Indicative data for Kalahari Sand soils of Botswana are presented as an illustration of the general performance characteristics.     

Paleopathological and Molecular Study on Two Cases of Ancient Childhood Leprosy from the Roman and Byzantine Empires

This study is based on the paleaopathology of leprosy on human skeletal remains and the detection of ancient Mycobacterium leprae DNA. Two cases of childhood leprosy were recognized. The first case was in a Roman necropolis at Martellona (Rome, Central Italy), dated to the 2nd to 3rd centuries ce . The skeleton of a child aged 4–5 years, from tomb 162, is the youngest individual in Italy from this time period, with the clear rhino‐maxillary syndrome and other bony changes indicative of leprosy. The second case from a burial at Kovuklukaya, in the Sinop region of Northern Turkey, was from the 8th to the 10th centuries, during the Byzantine era. The endocranium of a 4–5‐month‐old infant with new bone formation—an indication of chronic inflammation—was positive for M. leprae DNA. Infant and childhood leprosy is uncommon today, and there is a scarcity of information in the osteoarchaeological literature of leprosy in the past, especially in children. The significance of these cases is that it adds to an understanding of the history of the disease in the former Roman Empire. It is hoped that over time sufficient data can be obtained to understand the epidemiological dynamics and clinical evolution of leprosy from the ancient period until today.

Amenities,affordability, and housing vouchers

Against the background of an emerging rental affordability crisis, we examine how the standard rule that households should not spend more than 30% of their income on housing expenditures leads to inefficiencies in the context of federal low‐income housing policy. We quantify how the current practice of locally indexing individual rent subsidies in the Housing Choice Voucher (HCV) program regardless of quality‐of‐life conditions implicitly incentivizes recipients to live in high‐amenity areas. We also assess a novel scenario for housing policy reform that adjusts subsidies by the amenity expenditures of low‐income households, permitting national HCV program coverage to increase.     

Dwelling(s) in a north‐west Arabian oasis: decoding residential architecture at Taymāʾ

The definition of an ancient, autochthonous north‐west Arabian residential architecture is still a major void in the archaeology of the region. This preliminary case study is intended to shed some light on this “blind spot” by presenting and analysing the architectural complex E‐b9 from Taymā? (c. fourth/third century BCE until the first/early second century CE). A meticulous study of the architecture identified a modular concept as a key to understanding the complex. Furthermore, underlying patterns of household organisation can be deduced from the architectural remains resulting in the definition of potential household units. Those are indicated by a set of activity areas which are congruent with patterns of accessibility and the use of specific wall types. These findings provide insights into the organisation of households and daily life in the oasis of Taymā?, and may help to define local or regional traditions in the future.     

Genesis for Historians: Thomas Abbt on Biblical and Conjectural Accounts of Human Nature

Summary

Natural sociability and the basic features of human nature stood at the centre of Thomas Abbt's confrontation with conjectural history, the popular eighteenth-century mode of reconstructing the evolution of human culture. Abbt (1738–1766) criticised conjectural histories due to their arbitrary character, and opted for a synthetic approach consisting of both sacred and secular history. He suggested that the anthropology of Genesis should be accepted as the starting point for a conjectural history, since it left ample room for further questions and speculations. Yet his own perspective on human nature and its evolution remained naturalistic, as attested by his divergent interpretations of the confusion of tongues at Babel. Attempting to shed new light on the lesser-known elements of Abbt's work, the essay links his views on the Bible and conjectural history to his debate with Moses Mendelssohn over the constitution and destination of man. In this debate, both Mendelssohn and Abbt dealt with the contemporary controversy over the natural or artificial character of sociability, self-interest, and fellow-feeling.     

The Particle γάρ: From Ancient Greek Sentence Connector to Blatant Line Filler? A Case-study on the Late Medieval Greek Chronicle of Morea

Ancient Greek is widely regarded as a language with an extraordinary number of so-called “Wackernagel P2 particles” such as γ?ρ, δ(?), and μ?ν, which serve a multitude of discourse functions. From the post-Classical period on, however, these small words gradually lose their importance in discourse and die out. This is reflected in the interest of scholars: while there are many studies on particles in older stages of Greek, not much research has been conducted on the particles in late medieval Greek (LMG; twelfth to fifteenth centuries). At this stage of the Greek language, the P2 particles are acknowledged to no longer be part of the living spoken language. Nonetheless, some of these small words still turn up in texts written in the vernacular. Since most LMG vernacular literature is composed in the metre of the 15-syllabic πολιτικ?? στ?χο? (vernacular prose being extremely scarce in this period), these occurrences are traditionally explained by appealing to metrical and/or stylistic reasons: the particles constitute archaizing relics merely inserted to give a classicizing flavour to the text, or are even used “metri causa”, simply to achieve the required number of syllables. In this note, I present a case-study on the “explanatory” particle γ?ρ (“for”) in the Chronicle of Morea, the best-known verse chronicle of the Greek Middle Ages. I show that γ?ρ is more than a blatant line filler. First, γ?ρ is not at all distributed at random, but consistently occupies P2 and thus obeys the so-called “Law of Wackernagel”, as the particles in Ancient Greek do. Moreover, γ?ρ can still exert a clear discourse function, albeit often a different one than in Ancient Greek.
