Exploring the current and future role of market towns in servicing their hinterlands: a case study of Alnwick in the North East of England

Faced with the problems of access, distance and low population density, the provision of quality services to rural areas is inherently difficult. Although the role of market towns in alleviating problems in the provision of rural services has been given little consideration within the academic literature, they are currently being targeted by UK government policy. Using a case of the hinterland of Alnwick, a market town in the North East of England, this paper explores the current and future role of market towns in servicing their hinterlands. The results suggest a mutual dependence between market town services and hinterland residents and that the continuation of this relationship depends on market towns taking advantage of demographic trends in rural areas. Faced with changing demographics and the wider use of the Internet, potential is identified for ‘clawing-back’ trade from larger urban areas and creating an enhanced role for market towns. Extending the sense of belonging beyond the boundaries of the town itself will also be important in increasing patronage of town services.     

Determinants of presidential position taking in Congress, 1949–1995

In this paper we seek to explain the activity presidential position taking on roll call votes in the House. Position taking may help presidents pursue their policy agendas, but time and available resources constrain their ability to take positions. Even though position taking is a discretionary presidential action, it occurs in the legislative arena and, thus, presidents must consider elements in both institutions as well as outside conditions when making this decision. Accordingly, we posit a multiple perspectives approach to explain the number of presidential positions on votes in the House. Our multivariate two-stage least squares regression reveals that variables from all three environments (executive, legislative and exogenous) within our multiple perspectives approach are necessary to adequately explain presidential position taking overall and when divided according to domestic and foreign policy positions.     

Child Anger Regulation, Parental Responses to Children's Anger Displays, and Early Child Antisocial Behavior

The display and regulation of child anger in family interaction was coded in a sample of 240 boys and girls at child age 6, and coded using the Specific Affect Coding System. Child antisocial behavior was longitudinally assessed, beginning in kindergarten. Pooled‐ and family‐level analyses were used to assess hazard rates for child anger. Parents’ ability to modulate their own emotions and negative behavior, and children's ability to down‐regulate anger were associated with increased latency for child anger. Hazard for child anger increased as parents’ insensitive and negative responses toward the child cumulated during family interaction. Macro‐level, non‐hazard analyses indicated that chronic levels of child antisocial behavior were associated with the frequency of parental negative behavior, but not with the frequency of child anger. Micro‐level hazard analyses indicated that children's ability to regulate anger was related to chronic levels of child covert but not overt antisocial behavior.     

The importance of preservation of the ethical principle of equipoise in the design of clinical trials: relative impact of the methodological quality domains on the treatment effect in randomized controlled trials

Previous research has identified methodological problems in the design and conduct of randomized trials that could, if left unaddressed, lead to biased results. In this report we discuss one such problem, inadequate control intervention, and argue that it can be by far the most important design characteristic of randomized trials in overestimating the effect of new treatments. Current guidelines for the design and reporting of randomized trials, such as the Consolidated Standards of Reporting Trials (CONSORT) statement, do not address the choice of the comparator intervention. We argue that an adequate control intervention can be selected if people designing a trial explicitly take into consideration the ethical principle of equipoise, also known as "the uncertainty principle."     

The implementation of the bayesian paradigm

Routine implementation of the Bayesian paradigm requires an efficient approach to the calculation and display of posterior or predictive distributions for given likelihood and prior specifi- cations. In this paper we shall review some of the analytic and numerical approaches currently available, describing in detail a numerical integration strategy based on Gaussian quadrature, and an associated strategy for the reconstruction and display of distributions based on spline techniques.     

Simulation model of a predator-prey system comprised ofPhytoseiulus persimilis andTetranychus urticae. II. Model sensitivity to variations in the life history parameters of both species and to variations in the functional response and components of the numerical response

Summary A detailed sensitivity analysis of a model of a predator-prey system comprised ofTetranychus urticae andPhytoseiulus persimilis was performed. The aim was to assess the relative importance of the life history parameters of both species, the functional response, and the components of the numerical response. In addition, the impact of the initial predator-prey ratio and the timing of predator introduction were tested. Results indicated that the most important factors in the system were relative rates of predator and prey development, the time of onset of predator oviposition, and the mode of the predator's oviposition curve. The total oviposition of the predator, the effect of prey consumption on predator oviposition, and predator searching were important under some conditions. Factors of moderate importance were the adult female predator's functional response, total prey oviposition, the mode of the prey's oviposition curve, abiotic mortality of the pre-adult predator, and the effect of prey consumption on predator development and on the immature predator's mortality. Factors of least importance were the variances of the predator's and prey's oviposition curves, the abiotic mortality of the adult predator, the abiotic mortality of the pre-adult and adult prey, the functional response of the nymphal and adult male predators, and the effect of prey consumption on adult predator mortality. The sex ratios had little effect, except when the proportion of female predators was very low. The initial predator-prey ratio and time of predator introduction had significant impacts on system behavior, though the patterns of impact were different.
