Learnability Theory and the Acquisition of Syntax

It is now relatively uncontroversial that innate principles must be involved in language acquisition, but a crucial issue is the nature of these innate principles, in particular whether they are formulated as constraints on language or constraints on learning, or both (Wexler and Manzini 1987), and whether they are specific to language or can be related to other cognitive domains (O'Grady 1987). That is, are the acquisition mechanisms formulated in terms of linguistic principles, or are they formulated in terms of learning principles which are used to acquire a linguistic system? In either case the system acquired is linguistic, but the principles used to acquire it are not necessarily so, or may be partially so. In this paper I would like to explore a distinction between two theories of language acquisition, one which is based on universal grammar (UG), and one which is based on learnability theory (LT). The theory of universal grammar has been widely examined in both first and second language acquisition, whereas leamability theory is a relatively recent area of study which is being developed both within UG and from other theoretical perspectives (Wexler and Manzini 1987, Pinker 1984, O'Grady 1987, Rumelhart and McClellan 1987). For purposes of clarity, I would like to make a distinction between them as potentially different explanations for the developmental facts of language acquisition

Relational Selves in Eighteenth-Century Literature

We imagine the eighteenth century to be the time when modern individuals constituted themselves against the forces of communal obligation, when marriage emerged as a union based on singular affection, and when heterosexuality cohered as an ideology. But Relational Selves in Eighteenth Century Literature argues that a libertine logic of communal attraction, spontaneous affiliation, and transitory affection remains central to the literary production of modern selfhood in the eighteenth century. It thus departs from well-established critical narratives that entwine the modern self with the eighteenth-century emergence of sexual complementarity, the companionate marriage, and bourgeois individualism. I show instead how eighteenth-century literature privileged transient pleasures over more fixed models of companionship in the pursuit of selfhood. Reading works by James Thomson, Samuel Richardson, Eliza Haywood, and D.A.F. Sade, I argue that their literary portrayals of male and female selves cultivate a far more fluid sense of identity, one that ultimately derives from the libertine world of the Restoration and its fugitive desires. By insisting that the individual becomes bounded and autonomous through widely dispersed investments of affect, Relational Selves offers an alternative to modernizing narratives that see communal experiences as detracting from a highly particularized sense of self

Intra-individual variation in children\u27s physical activity patterns: Implications for measurement

Children\u27s physical activity (PA) patterns change form day to day. This intra-individual variability affects precision when measuring key physical activity and sedentary behavior variables. This paper discusses strategies to reduce the random error associated with intra-individual variability and demonstrates the implications for assessing PA when varying number of days are sampled. Self-reported data collected on two hundred and ninety eight 13- to 14-year-olds were used to compare estimates of PA and sedentary behaviour derived from between 1 and 7 days of recall data. Large intra-individual coefficients of variation were calculated for physical activity level (14.5%), moderate-to-vigorous physical activity (83.4%), screen time (60.8%) and sleep (12.2%). While the magnitude of error associated with estimating means decreased as more days were sampled, the paper notes that depending on the nature of the research question being asked, fewer days may yield sufficiently precise estimates. Therefore, researchers should conduct power analyses based on estimated inter- and intra-individual variability and sample size to determine how many days to sample when assessing children\u27s PA patterns

Doing research in care homes: the experiences of researchers and participants

The UK Prime Minister's Challenge on Dementia 2020 includes a target for more research to be conducted in care homes, yet research in care homes can be complex, as they are both homes and workplaces. We reflect on our experiences as researchers on a mixed methods study in six care homes over a year. We include the experiences of care home residents, their family and friends, and members of staff. Care home staff turnover was high, funding was constrained and priorities often differed from those of the researchers. Negotiating ongoing access and data collection was therefore challenging at times. Most residents did not mind taking part, but those who preferred not to felt able to decline. Private space was limited. Research in care homes needs to be adequately planned and resourced, including funding for staff time, if staff, residents and visitors are to participate in a meaningful way

A Late Bronze Age ring-forst at Bayvil Farm, Pembrokeshire

A 70m-diameter circular ditched enclosure identified as a cropmark in 1996 at Bayvil Farm, Eglwyswrw, north Pembrokeshire, was initially thought to be a segmented-ditched enclosure, an early type of Neolithic henge. Geophysical survey in 2012–13 and partial excavation in 2014 has shown it to be Late Bronze Age ring-fort dating to the eleventh-tenth centuries BC and subsequently occupied during the Early Iron Age. Late Bronze Age circular enclosures of this kind are well known in eastern England but this is the first such ring-fort to be discovered in Wales. A medieval corn-dryer identified by geophysical survey was also excavated which is probably to be associated with the probable traces of the medieval settlement of Bayvil, associated with the redundant St Andrew’s Church which has possible medieval origins

The association between sedentary behaviour and risk of anxiety: a systematic review

BACKGROUND: Previous research has linked sedentary behaviour (SB) to adverse physical health outcomes in adults and youth. Although evidence for the relationship between SB and mental health outcomes (e.g., depression) is emerging, little is known regarding risk of anxiety. METHODS: A systematic search for original research investigating the association between SB and risk of anxiety was performed using numerous electronic databases. A total of nine observational studies (seven cross-sectional and two longitudinal) were identified. Methodological quality of studies was assessed and a best-evidence synthesis was conducted. RESULTS: One cross-sectional study demonstrated a strong methodological quality, five cross-sectional studies demonstrated a moderate methodological quality and three studies (two cross-sectional one longitudinal) received a weak methodological quality rating. Overall, there was moderate evidence for a positive relationship between total SB and anxiety risk as well as for a positive relationship between sitting time and anxiety risk. There was inconsistent evidence for the relationship between screen time, television viewing time, computer use, and anxiety risk. CONCLUSION: Limited evidence is available on the association between SB and risk of anxiety. However, our findings suggest a positive association (i.e. anxiety risk increases as SB time increases) may exist (particularly between sitting time and risk of anxiety). Further high-quality longitudinal/interventional research is needed to confirm findings and determine the direction of these relationships

Excavations at Castell Mawr Iron Age hillfort, Pembrokeshire

Castell Mawr is a small hillfort in the community of Eglwyswrw, Pembrokeshire. Thought to have been built on a Late Neolithic henge, it was investigated with four trenches in 2012–13. These excavations revealed that Castell Mawr’s main period of construction and use was in the Earliest/Early Iron Age during the late eighth–late fifth centuries BC with hints of an earlier human presence on the hilltop in the Late Mesolithic and Bronze Age. No definite evidence of any Neolithic activity was found, however, and the earthworks all date to the Iron Age. The hillfort’s Iron Age sequence started with a roundhouse, followed by a pair of concentric timber palisades built during the late eighth–late fifth centuries BC. An enclosing rampart was constructed around the hilltop, followed by a cross-bank. The final activity post-dating the cross-bank dates to the fifth century BC, slightly earlier than or contemporary with initial construction at nearby Castell Henllys. The Castell Mawr/Castell Henllys sequence confirms Murphy and Mytum’s (2012) model for long-term processes of settlement development in west Wales

Can general practitioner commissioning deliver equity and excellence? : Evidence from two studies of service improvement in the English NHS

Objectives: To explore some of the key assumptions underpinning the continued development of general practitioner-led commissioning in health services. Methods: Qualitative data from two studies of service improvement in the English NHS were considered against England's plans for GP-led commissioning. These data were collected through in-depth interviews with a total of 187 professionals and 99 people affected by services in 10 different primary care trust areas across England between 2008 and 2009. Results: Internationally, GPs are seen to have a central position in health systems. In keeping with this, the English policy places emphasis on the 'pivotal role' of general practitioners, considered to be ideally placed to commission in the best interests of their patients. However, our evidence suggests that general practitioners do not always have a pivotal role for all patients. Moreover, it is planned that the new commissioning groups in England will not be subject to top-down performance management and this raises the question of how agreed quality standards will be met under the proposed new system. Conclusions: This paper questions the assumption that GPs are best placed to commission health services in a way that meets quality standards and leads to equitable outcomes. There is little evidence to suggest that GPs will succeed where others have failed and a risk that, without top-down performance management, service improvement will be patchy, leading to greater, not reduced, inequity
