The paper contrasts two opposed strategies of land-use planning: the classical planning strategy of containment and conservation, and the strategy for outward displacement of land uses, here designated ‘Lemmings Rule’. It is shown how Lemmings Rule which has characterized recent years in Britain, despite the existence of the planning machine, has resulted in large-scale waste of the land resource through various landuse zones outward from the inner city. Statistics derived from the Second Land Utilisation Survey of the 1960s and sample resurveys of the 1970s are cited in support of the argument for a return to the insurance principle in planning.  相似文献

Recent patterns of fertility in Europe show marked differences between countries. Recent United Kingdom and Irish fertility curves show 'distortions' in terms of a 'bulge' in early age fertility, distinct from the smoother curves of other European countries. These patterns may not be adequately described by mathematical functions used by previous studies to model fertility curves. A mixture model with two component distributions may be more appropriate. The suitability of the simple and mixture Hadwiger functions is examined in relation to the fertility curves of a number of European countries. While the simple Hadwiger model fits recent period age-specific fertility distributions for some countries, others which display a 'bulge' in early age fertility distributions for some countries, others which display a 'bulg' in early age fertility require a mixture Hadwiger model. Some of the parameters of the Hadwiger models appear to be related to familiar demographic indices. The simple and mixture Hadwiger models appear useful in describing and comparing fertility patterns across European countries.  相似文献

ABSTRACT

An enduring challenge for HRD is ensuring academic research achieves impact on professional practice. We have located this research within debates about the research-practice gap. To investigate this challenge, we analyse case studies of academic impact from all disciplines submitted to the United Kingdom’s 2014 research assessment exercise (REF 2014). We found that Learning and Development was a primary focus of significant number of impact case studies submitted across all disciplines compared to other areas of HR and HRD. We also found that Learning and Development was a key path to Impact. These findings reveal that Learning and Development in a work context plays a pivotal role in helping researchers irrespective of discipline achieve impact. Our findings therefore speak to the research-practice gap across academia. We conclude by considering the potential role for HRD in generating impact.  相似文献

A novel extension of traditional growth models for exposure assessment of food-borne microbial pathogens was developed to address the complex interactions of competing microbial populations in foods. Scenarios were designed for baseline refrigeration and mild abuse of servings of chicken broiler and ground beef Our approach employed high-quality data for microbiology of foods at production, refrigerated storage temperatures, and growth kinetics of microbial populations in culture media. Simple parallel models were developed for exponential growth of multiple pathogens and the abundant and ubiquitous nonpathogenic indigenous microbiota. Monte Carlo simulations were run for unconstrained growth and growth with the density-dependent constraint based on the "Jameson effect," inhibition of pathogen growth when the indigenous microbiota reached 10(9) counts per serving. The modes for unconstrained growth of the indigenous microbiota were 10(8), 10(10), and 10(11) counts per serving for chicken broilers, and 10(7), 10(9) and 10(11) counts per serving for ground beef at respective sites for backroom, meat case, and home refrigeration. Contamination rates and likelihoods of reaching temperatures supporting growth of the pathogens in the baseline refrigeration scenario were rare events. The unconstrained exponential growth models appeared to overestimate L. monocytogenes growth maxima for the baseline refrigeration scenario by 1500-7233% (10(6)-10(7) counts/serving) when the inhibitory effects of the indigenous microbiota are ignored. The extreme tails of the distributions for the constrained models appeared to overestimate growth maxima 110% (10(4)-10(5) counts/serving) for Salmonella spp. and 108% (6 x 10(3) counts/serving) for E. coli O157:H7 relative to the extremes of the unconstrained models. The approach of incorporating parallel models for pathogens and the indigenous microbiota into exposure assessment modeling motivates the design of validation studies to test the modeling assumptions, consistent with the analytical-deliberative process of risk analysis.  相似文献

In this paper, I will attempt to address questions about the dynamics of anorexia within family relationships, the ways in which anorexic thinking encapsulates itself in the mind, and how it can leave both the therapist and the family feeling ‘starved out’. I will also address some organisational issues, in the ways the therapeutic agency can come to mirror the anorexic dilemma. How does the metaphor of ‘growing’ and ‘growing up’ join with the anorexic crisis? I will discuss the cases of both a boy and a girl with anorexia, in order to think about the dynamic differences in the ‘becoming of a man’ and the ‘becoming of a woman’.  相似文献

Problem

Supplementation of breastfed babies is common during the hospital stay.

Background

The Baby Friendly Hospital Initiative (BFHI) optimises practices to support exclusive breastfeeding, yet supplementation is still prevalent.

Objective

To determine predictors for supplementation in a cohort of breastfed babies in a Baby-Friendly hospital.

Methods

Electronic hospital records of 1530 healthy term or near term singleton infants and their mothers were examined retrospectively and analysed to identify factors associated with in-hospital supplementation using Poisson regression (unadjusted and adjusted).

Findings

Fifteen percent of breastfed infants were supplemented during their hospital stay. Analysis by multivariable Poisson regression found that supplementation was independently associated with overweight (reference normal weight) (aRR [adjusted relative risk] = 1.46; 95% CI: 1.11–1.93); primiparity (aRR = 1.40; 95% CI: 1.09–1.80); early term gestation (37–376 weeks, aRR = 2.79; 95% CI: 1.88–4.15; 38–386 weeks, aRR = 2.03, 95%CI: 1.46–2.82); birthweight less than 2500 grams (reference 3000–3499 grams) (aRR = 3.60; 95% CI: 2.32–5.60) and use of postpartum uterotonic (aRR = 2.47; 95% CI: 1.09–5.55). Greater than 65 minutes of skin-to-skin contact at birth reduced the risk of supplementation (aRR = 0.66; 95% CI; 0.48–0.92).

Conclusion

These identified predictors for supplementation, can inform the development of interventions for mother-infant pairs antenatally or in the early postpartum period around increased breastfeeding education and support to reduce supplementation. It may also be possible to reduce supplementation through judicious use of postpartum uterotonics and facilitation of mother-infant skin-to-skin contact at birth for greater than one hour duration.  相似文献
