Environmental distribution of Bathonian (Middle Jurassic) neoselachians in southern England

Within the Bathonian (Middle Jurassic) a wide range of depositional environments were present across Britain. Within this dominantly carbonate shelf setting, there is a general palaeoenvironmental transition from open marine shelf in the south of England, to marine and non-marine lagoons in south-central England. Isolated teeth of neoselachians are frequent at several localities within a range of marine and lagoonal facies. Extensive bulk sampling has allowed teeth from over 20 neoselachian taxa to be recovered from several distinct facies. The distributions of many species suggest that they were strongly environmentally controlled, with few taxa being commonly present within both open marine and lagoonal settings. Some taxonomic groups appear to have been restricted to specific environments, with hexanchids and palaeospinacids only being recorded within open marine facies. Within other groups, environmental segregation is at generic and specific level, with different species of Protospinax, orectolobids, batoids and scyliorhinids being recorded within different facies. The differential distribution of neoselachians within the Bathonian demonstrates that the initial phase of neoselachian radiation during the late Early and Middle Jurassic was accompanied by diversification into a wide range of ecological niches. This greatly increases our understanding of the mechanisms and timing of neoselachian radiation and Jurassic fish palaeoecolog

Gurindji people and Aboriginal self-determination policy, 1973-1986

In 1973, a newly-elected Australian Labor Party government led by Gough Whitlam described its new Aboriginal Affairs policy as one of Aboriginal self-determination. The policy proclaimed its intention to assist Aboriginal groups to achieve their own goals, and used the Northern Territory (over which the Commonwealth then had full control) as a proving ground for its implementation. Subsequently renamed self-management by the Fraser Government (1975–83), the policy was adapted in small but significant ways by every federal and Northern Territory Government in the period of this study (1973–86). The thinking of those who had formulated self-determination policy had been influenced by the situation and ambitions of the Gurindji people. The group had come to public attention following their Wave Hill Walk-off protest action of 1966, led by Vincent Lingiari. In the years afterwards, Lingiari and other Gurindji leaders articulated a number of goals, the achievement of which they saw as fundamental to their society’s wellbeing and viability. Those goals were: official recognition of their traditional rights to land; their operation of a cattle enterprise on that land; their establishment of an independent community there also; and the operation in that community of a ‘two-way’ school. This thesis recognises an apparent confluence of shared intentions among Gurindji leaders and government agencies in the self-determination era, and describes a zone of parallel Gurindji and government activity: ‘Gurindji self-determination’. Finding that three of Gurindji self-determination’s four goals were not or only fleetingly achieved, the task of this thesis is to identify the causes of this broad failure and singular success. To do this, the thesis draws on detailed empirical data, the policy history of the preceding decades, anthropological and ethnographic studies, and political theory. This thesis finds that Gurindji self-determination’s failure was caused by inchoate and emergent differences between the aims and methods of government agencies and the Gurindji. Equally, young Gurindji people’s social reform agendas were an important and unanticipated contributor to the failure of Gurindji self-determination. Increased cash incomes and broader policy shifts associated with ‘equal rights’ enabled younger Gurindji to conduct this reformation

Victory, disaster or scapegoat? Aboriginal 'self-determination' policy in the Northern Territory during the 1970s

It is commonly understood that the federal policy of Aboriginal self-determination was responsible for significant changes that occurred in the Territory's remote Aboriginal Indigenous settlements in the 1970s. Rather than the administrative changes that self-determination policy entailed, broader policy shifts associated with 'equal rights' enabled remote Indigenous people to enact their own agendas of reform. This reformism brought deep and lasting changes to the Territory's Indigenous nations, and shaped the modus operandum of the "communities" and town camps created by self-determination policy. This paper sheds new light on a controversial period in Territory history that has had lasting effects

Building Wealth Through Ownership: Resident-Owned Manufactured Housing Communities in New Hampshire

Eighty-two resident-owned manufactured housing parks serve over 4,000 New Hampshire families. Despite their popularity, one important question remains: do they outperform investor-owned manufactured housing parks from a social and economic standpoint? A research team from UNH set out to answer this question through a comprehensive study that engaged subjects from resident-owned parks and investor-owned parks and officials from seven New Hampshire towns. The research findings suggest that resident-owned manufactured housing parks indeed provide a more affordable housing option for low-income families, as well as an enhanced sense of ownership and an opportunity to build equity. Implications for Extension are discussed

Neoselachian sharks and rays from the British Bathonian (Middle Jurassic)

Extensive sampling of Bathonian sediments from localities across southern and central England has produced over 8000 neoselachian teeth. These comprise diverse faunas, with over 25 species being represented in total, most of them previously undescribed. Seventeen new species and seven new genera are named: Palaeoscyllium tenuidens sp. nov., Praeproscyllium oxoniensis gen. et sp. nov., Eypea leesi gen. et sp. nov., Proheterodontus sylvestris gen. et sp. nov., Paracestracion bellis sp. nov., Palaeobrachaelurus mussetti sp. nov., Heterophorcynus microdon gen. et sp. nov., Dorsetoscyllium terraefullonicum gen. et sp. nov., Ornatoscyllium freemani gen. et sp. nov., Pseudonotidanus semirugosus gen. et sp. nov., Synechodus duffini sp. nov., Protospinax magnus sp. nov., P. bilobatus sp. nov., P. carvalhoi sp. nov., Belemnobatis kermacki sp. nov., B. stahli sp. nov. and Spathobatis delsatei sp. nov. In addition, a new family, the Pseudonotidanidae fam. nov., is defined and the status of Paranotidanus Ward and Thies, 1987, Hybodus levis Woodward, 1889 and Breviacanthus brevis (Phillips, 1871) are discussed. These taxa show strong facies specificity, with different species being restricted to different palaeoenvironments

Palaeontology, stratigraphy and sedimentology of Woodeaton Quarry (Oxfordshire) and a new microvertebrate site from the White Limestone Formation (Bathonian, Jurassic)

Woodeaton Quarry in Oxfordshire has previously yielded a number of large sauropod vertebrae and other (unpublished) dinosaur remains from a horizon in the Rutland Formation. No review of the wider terrestrial fauna from Woodeaton has been published to date. Here we present an overview of new material recovered from a microvertebrate site at the top of the White Limestone Formation (Middle Jurassic, Bathonian, Great Oolite Group, Retrocostatum Zone) and review the stratigraphy to provide a comprehensive local stratigraphic framework and place the quarry in the correct regional context. The terrestrial fauna is similar to that found from other UK Bathonian microvertebrate sites and includes probable dromaeosaurid theropods, ornithischians, tritylodontids and mammaliaforms such as amphitheriids, docodonts, ‘eutriconodonts’, ‘haramyids’ and multituberculates. Placement of the White Limestone Formation boundaries are clarified with respect to the Rutland and Forest Marble Formations. This indicates that the microvertebrate bed from Woodeaton is slightly older than that of the well-known mammal bed from nearby Kirtlington Quarry

High-Performance Integrated Window and Façade Solutions for California

The researchers developed a new generation of high-performance façade systems and supporting design and management tools to support industry in meeting California’s greenhouse gas reduction targets, reduce energy consumption, and enable an adaptable response to minimize real-time demands on the electricity grid. The project resulted in five outcomes: (1) The research team developed an R-5, 1-inch thick, triplepane, insulating glass unit with a novel low-conductance aluminum frame. This technology can help significantly reduce residential cooling and heating loads, particularly during the evening. (2) The team developed a prototype of a windowintegrated local ventilation and energy recovery device that provides clean, dry fresh air through the façade with minimal energy requirements. (3) A daylight-redirecting louver system was prototyped to redirect sunlight 15–40 feet from the window. Simulations estimated that lighting energy use could be reduced by 35–54 percent without glare. (4) A control system incorporating physics-based equations and a mathematical solver was prototyped and field tested to demonstrate feasibility. Simulations estimated that total electricity costs could be reduced by 9-28 percent on sunny summer days through adaptive control of operable shading and daylighting components and the thermostat compared to state-of-the-art automatic façade controls in commercial building perimeter zones. (5) Supporting models and tools needed by industry for technology R&amp;D and market transformation activities were validated. Attaining California’s clean energy goals require making a fundamental shift from today’s ad-hoc assemblages of static components to turnkey, intelligent, responsive, integrated building façade systems. These systems offered significant reductions in energy use, peak demand, and operating cost in California

Paleogene origin of Planktivory In The Batoidea

The planktivorous mobulid rays are a sister group to, and descended from, rhinopterid and myliobatid rays which possess a dentition showing adaptations consistent with a specialized durophageous diet. Within the Paleocene and Eocene there are several taxa which display dentitions apparently transitional between these extreme trophic modality, in particular the genus Burnhamia. The holotype of Burnhamia daviesi was studied through X-ray computed tomography (CT) scanning. Digital renderings of this incomplete but articulated jaw and dentition revealed previously unrecognized characters regarding the jaw cartilages and teeth. In addition, the genus Sulcidens gen. nov. is erected for articulated dentitions from the Paleocene previously assigned to Myliobatis. Phylogenetic analyses confirm Burnhamia as a sister taxon to the mobulids, and the Mobulidae as a sister group to Rhinoptera. Shared dental characters between Burnhamia and Sulcidens likely represent independent origins of planktivory within the rhinopterid – myliobatid clade. The transition from highly-specialized durophagous feeding morphologies to the morphology of planktivores is perplexing, but was facilitated by a pelagic swimming mode in these rays and we propose through subsequent transition from either meiofauna-feeding or pelagic fish-feeding to pelagic planktivory
