Physical and mental relationships : an historical survey of the attempts to find a relationship between physical growth and intelligence, and physique and temperament

The relationship of mind and body has long claimed man's attention. Early enquiries into the relationship of these two aspects of development have presumed that physical and mental growth were related functionally, that their growth proceeded together at a similar rate, and that any defect of one would immediately show itself in the other. The relationship occupied the minds of such men as Hippocrates, Plato and Aristotle, and many since have seen the relationship and guessed its nature.

Are invasive hymenopteran species replacing native mud dauber wasp-associated taxa on the Seychelles Archipelago?

Nest aggregations of mud dauber wasps increase substrate heterogeneity and provide suitable sites for colonization by other invertebrate species. The mud dauber wasp Sceliphron fuscum Klug, 1801 (Hymenoptera: Sphecidae) abundantly occurs throughout the Seychelles Archipelago, Republic of Seychelles. Here, we estimated the taxonomic richness of the hymenopteran assemblage associated with S. fuscum’s nest aggregations, using material collected from the Inner Seychelles in 2016. Furthermore, we examine available historical survey data in order to assess possible changes in this association over decades. We discovered that from 1936 to 1938, seven hymenopteran species were associated with the nest aggregations of S. fuscum on Mahé and Praslin islands, representing six native taxa and one invasive species. From the material collected in 2016, we found one native and three invasive hymenopteran species associated to S. fuscum nests. Our findings could indicate a replacement of native species associated with the mud dauber wasps’ nest aggregations by recently introduced alien taxa on the Seychelles Archipelago.

150 YEARS OF SHIP DESIGN

As part of writing a short article entitled “Ship Design – From Art to Science?” [1] for the Institution’s 150th anniversary celebratory volume [2], the author consulted the Institution’s centenary book by K C Barnaby [3] to get a feel for the formative first hundred years of ship design recorded in the learned papers presented to the Institution. This consultation was motivated by consideration of the papers in the first volume of the Transactions of 1860, which, surprisingly, contained no papers directly on ship design, either on ship design in general or through describing the design intent behind a specific new ship. Rather, like the very first paper by Reverend J Woolley, the remaining 1860 papers concerned themselves with what could be called the application of science (and mathematics) to the practice of naval architecture as an engineering discipline. However this initial focus broadened out in subsequent volumes of the Transactions so that both technical descriptions of significant new ship designs and, more recently, papers on the general practice of ship design have also figured, alongside the presentation of progress in the science of naval architecture. Given that the vast bulk of ships built over this period have been designed like most buildings to a set pattern, or as we naval architects would say based on a (previous) “type ship”, those designs presented in the Institution’s Transactions, and the few other collections of learned societies’ papers, are largely on designs that have been seen to be of particular merit in their novelty and importance. Therefore this review looks at the developments in ship design by drawing on those articles in the Transactions that are design related. In doing so the papers have been conveniently broken down into the three, quite momentous, half centuries over which the Institution has existed. From this historical survey, it is then appropriate to consider how the practice of ship design may develop in the foreseeable future.

Film Music in Concert

The Boston Pops Orchestra was the first orchestra of its kind in the USA: founded in 1885 from the ranks of the Boston Symphony Orchestra, its remit was to offer concerts of light symphonic music. Over the years, and in particular during the fifty-year tenure of its most famous conductor, Arthur Fiedler, the Pops established itself as the premier US orchestra specialising in bridging the fields of 'art music' and 'popular music'. When the Hollywood composer John Williams was assigned the conductorship of the orchestra in 1980, he energetically advocated for the inclusion of film-music repertoire, changing Fiedler's approach significantly. This Element offers a historical survey of the pioneering agency that the Boston Pops had under Williams's tenure in the legitimisation of film music as a viable repertoire for concert programmes. The case study is complemented with more general discussions on the aesthetic of film music in concert.

Impacts of a Non-indigenous Ecosystem Engineer, the American Beaver (Castor canadensis), in a Biodiversity Hotspot

Non-native species having high per capita impacts in invaded communities are those that modulate resource availability and alter disturbance regimes in ways that are biologically incompatible with the native biota. In areas where it has been introduced by humans, American beaver (Castor canadensis) is an iconic example of such species due to its capacity to alter trophic dynamics of entire ecosystems and create new invasional pathways for other non-native species. The species is problematic in several watersheds within the Southern California-Northern Baja California Coast Ecoregion, a recognized hotspot of biodiversity, due to its ability to modify habitat in ways that favor invasive predators and competitors over the region's native species and habitat. Beaver was deliberately introduced across California in the mid-1900s and generally accepted as non-native to the region up to the early 2000s; however, articles promoting the idea that beaver may be a natural resident have gained traction in recent years, due in large part to the species' charismatic nature rather than by presentation of sound evidence. Here, we discuss the problems associated with beaver disturbance and its effects on conserving the region's native fauna and flora. We refute arguments underlying the claim that beaver is native to the region, and review paleontological, zooarchaeological, and historical survey data from renowned field biologists and naturalists over the past ~160 years to show that no evidence exists that beaver arrived by any means other than deliberate human introduction. Managing this ecosystem engineer has potential to reduce the richness and abundance of other non-native species because the novel, engineered habitat now supporting these species would diminish in beaver-occupied watersheds. At the same time, hydrologic functionality would shift toward more natural, ephemeral conditions that favor the regions' native species while suppressing the dominance of the most insidious invaders.

Chapter 1: Russia’s Foreign Food Trade: An Historical Survey

The chapter utilises four variables to examine Russia’s food trade from the 1970s to the present. The four variables include: frequency of entrance into the global food market; degree of food trade protectionism; degree of integration with Western global trading institutions; and degree of involvement in the global food market. For the period since 2014, the chapter concludes that the frequency of Russia’s entrance into the global food market is likely to remain high as an annual importer and exporter. Agricultural protectionism is likely to remain selectively high. The degree of integration with Western trade institutions is likely to remain low. Russia’s degree of involvement with the global food market is likely to remain high.
