县域生态保护成效评估方法——以峨山县为例

县域是我国基本的行政单元,建立县域生态保护成效评估方法是完善我国生态文明制度建设重要任务。生态系统生产总值(GEP)是指一定区域在一定时期内生态系统为人类福祉提供的最终产品与服务及其价值总和,开展县域GEP核算可以客观反映县域的生态系统状况和生态保护的成效。以省级生态文明县——峨山彝族自治县为例,研究了县域GEP的核算指标体系和核算方法,开展了峨山县GEP核算,分析了峨山县GEP构成及其变化趋势。结果表明:(1)峨山县生态系统产品与服务可以分为产品提供、调节服务和文化服务3大类15项;(2)2015年,峨山县GEP为158.42亿元,气候调节功能和水源涵养功能是最主要的服务功能,二者总和占当年GEP的62.02%;(3)2000年以来,峨山县GEP明显提高,剔除价格因素后,共增加了25.04%,其中产品提供和文化服务功能价值提升明显,分别增加了236.25%和3004.06%。调节服务价值稳中有升,增加了1.30%。本研究表明,现有的生态环境监测数据和经济社会统计数据基本上可以支撑县域GEP的核算,同时县域GEP的变化能够体现出生态系统的保护成效,并为完善政府绩效考核制度提供依据。     

基于ISM的国家森林公园生态福利供给系统评价指标体系研究

国家森林公园作为生态福利供给的载体之一,具有带动经济发展、提供文化教育以及游憩、康养的复合功能,是平衡经济社会发展和生态保护,满足人民日益增长的美好生活需要的重要途径。从生态福利的概念出发,结合系统理论,以黑龙江省为例构建了国家森林公园生态福利供给评价指标体系,并利用解释结构模型（Interpretative Structural Modeling,ISM）确定了生态福利供给系统内部要素的递阶结构,从ISM结果得出以下结论：（1）国家森林公园生态福利供给系统表层影响因素主要包括身体健康（S01）,心理健康（S02）,地方感（S04）等8个内部要素;表层影响因素直接关系森林公园生态福利的供给。（2）国家森林公园生态福利供给系统中层影响因素包括21个内部因素;中层影响因素可以直接作用于表层因素,对其中可人为控制的因素进行干预是提高生态福利供给的重要路径之一。（3）国家森林公园生态福利供给系统深层影响因素包括游步道总数（S09）,森林公园植物多样性（S14）,林业相关科研和教育的投入（S16）,环境建设与保护投入（S27）,当年植树造林面积（S30）五个内部因素;深层影响因素具有多途径影响性和可控性,对其进行规划是国家森林公园提供高质量生态福利的主要手段。     

Care of the diabetic child in the community.

Brief admission of the new diabetic child and of a parent to an enlightened hospital for stabilisation, preliminary education, and familiarisation with hospital and community staff is well worth while. The greater the demand for constant control of the highest quality, the greater the need for a close understanding of the psychosocial factors concerned and for clinical skill. The nature of the home and the family relationships should in theory be available from the child''s general practitioner at the time of the first referral since he has so much information about the whole family. With the virtual disappearance, however, of mutual consultation in the patient''s home in many places, the opportunity for oral communication has declined, and availability on the telephone is not always easy. The busy general practitioner (far less an unknown physician from a deputising service without access to the records) has little time to write a comprehensive letter. In practice a relatively small hospital-based mobile team of specially experienced sisters who are keen to communicate in the home, the GP''s surgery, and the school makes a major contribution to the diabetic care of a young population vulnerable to major handicap in what should be the prime of life. Their cost effectiveness may be difficult to prove but it is not at all in doubt--especially when the sisters as in this area deal in the community with a wider range of chronic illnesses and handicaps in children.     

Effectiveness of out-of-home day care for disadvantaged families: randomised controlled trial

Objective To assess the effects of providing daycare facilities for young children on the health and welfare of disadvantaged families.Design Randomised controlled trial. Eligible children from the application list to a daycare facility were randomly allocated to receive a daycare place or not.Setting Early Years daycare centre in Borough of Hackney, London.Participants 120 mothers and 143 eligible children (aged between 6 months and 3.5 years).Intervention A place at the centre, which provided high quality day care. Control families used other child care that they secured for themselves.Main outcome measures Maternal paid employment, household income, child health and development.Results At 18 months'' follow up, 67% of intervention group mothers and 60% of control group mothers were in paid employment (adjusted risk ratio 1.23 (95% confidence interval 0.99 to 1.52)), but were no more likely to have a weekly household income of above £200 (risk ratio 0.88 (0.70 to 1.09)). Intervention group children had more otitis media with effusion (risk ratio 1.74 (1.02 to 2.96)) and used more health services (1.58 (1.05 to 2.38)), but both estimates were imprecise.Conclusion The provision of child day care may have increased maternal employment, but it did not seem to increase household income. The results suggest that providing day care may be insufficient as a strategy to reduce poverty. The study shows how random allocation can be used to ration and evaluate interventions where demand exceeds supply.     

牧户的草原生态补偿政策满意度与支持度——基于CSI框架和SEM的检验

从生计和生态双重维度探究牧户的草原生态补偿政策满意度与支持度,对于深化草原生态补偿制度改革,促进草原生态文明建设和牧区绿色发展,具有重要的理论与现实意义。基于马克思“生态经济人”预设的微观视角,以费耐尔满意度逻辑模型(CSI)为理论框架,使用2020年若尔盖草原574个牧户调研数据,通过反映性指标的结构方程模型(SEM),对牧户草原生态补偿政策满意度和支持度的因果机制进行了多变量、多路径的验证性分析。结果表明：(1)牧户对生计收入和生态质量越重视、“生态经济人”理性越高,其政策满意度就越高,生态保护的心理主动性也越大,相对效应大小=0.271。(2)牧户对政策实施结果的质量评价,是牧户政策满意度和支持度的主要影响因素,相对效应大小=0.518。(3)牧户对政策实施效果的价值感知,将会直接提升其政策满意度,并进一步促进其生态保护理性,相对效应大小=0.312。因此,提高牧户对草原生态补偿政策的满意度与支持度,应重点从三个维度综合施策：首先,应重视发展草原生态文化,培育牧户生态经济理性。其次,要稳步提升生态补偿标准,加强草原保护的工作力量,提升政策实施结果的质量。最后,草原生态补偿要重点加...     

The one child family policy: the good,the bad,and the ugly.

Rapid population growth in China during the 1950s and ''60s led to the "late, long, few" policy of the 1970s and a dramatic reduction in the total fertility rate. However, population growth remained too high for the economic targets of Deng Xiao Ping''s reforms, so the one child family policy was introduced in 1979 and has remained in force ever since. The strategy is different in urban and rural areas, and implementation varies from place to place depending on local conditions. The policy has been beneficial in terms of curbing population growth, aiding economic growth, and improving the health and welfare of women and children. On the negative side there are concerns about demographic and sex imbalance and the psychological effects for a generation of only children in the cities. The atrocities often associated with the policy, such as female infanticide, occur rarely now. China may relax the policy in the near future, probably allowing two children for everyone.     

Diagnostic value of microtympanometry in primary care.

OBJECTIVE--To determine the reliability, validity, and feasibility of a new hand held microtympanometer. DESIGN--Comparison of microtympanometry by two independent observations of a general practitioner and a nurse, and against a validated reference instrument. SETTING--Primary care health centre of a school for the deaf in the United States. SUBJECTS--111 schoolchildren receiving a regular check up. MAIN OUTCOME MEASURES--Tympanometry with the Grason Stadler 28, classified with a slightly modified Jerger''s classification. RESULTS--Interobserver reliability was 0.95 (Cohen''s kappa). Results of microtympanometry were highly comparable with results of the reference instrument (likelihood ratio of positive results, 161.2). CONCLUSIONS--The microtympanometer could be used in general practice: it is hand held, child friendly, easy to handle, and accurate.     

牧民对草地生态补偿政策的满意度实证研究

实施草地生态补偿政策是恢复退化草地、建设生态安全屏障、提高牧民生活水平,促进牧区社会经济发展的重要手段。研究牧民对草地生态补偿政策的满意度及其影响因素,对完善我国草地生态补偿政策,提高补偿绩效具有重要意义。选取甘肃牧区中甘南、肃南和天祝三地500户牧民作为样本数据,结合问卷调查与深度访谈,构建有序Logit模型,从牧民一般社会经济特征、对其居住与放牧地区生态环境评估,以及对生活满意度评估三方面入手研究了牧民对草地生态补偿政策实施的满意度及其影响因素。结果表明,影响牧民对补偿政策满意度的显著因素包括牧民受教育水平、牲畜养殖数量与体重变化情况、补偿金额、牧民对环境与经济重要性的评估,以及对社会福利满意度的主观评价。从政策角度看,提高牧民受教育水平,改变牧民传统放牧观念;改善贫困牧民生活水平,提高牧民社会福利;优化补偿方式,构建补偿政策监管体系,有利于草地生态补偿政策的进一步完善与有效实施。

甘孜藏族自治州(以下简称甘孜州)生态状况良好而经济相对滞后,评估甘孜州生态系统服务功能及其价值,对甘孜州社会经济的可持续发展具有一定的促进作用。通过核算甘孜州的生态系统生产总值(GEP),包括对甘孜州的产品提供服务、调节服务和文化服务进行价值评估,以期用直观的经济数据揭示甘孜州生态系统对人们的直接贡献。核算结果显示,甘孜州2010年全州生态系统生产总值(GEP)为7545.59亿元,人均71.18万元,是当年该州国内生产总值(GDP)和人均GDP的约61倍。其中,调节服务的价值最大,为6842.28亿元,占GEP总值的90.68%;产品提供服务和文化服务的价值分别为632.64亿元和70.67亿元,占GEP的8.38%和0.94%。研究认为甘孜州生态系统服务功能价值巨大,保护甘孜州生态系统就是保护人们的福祉,该结果可以为甘孜州的生态系统管理、生态保护和生态补偿提供重要依据。     

Plasma-collection plant has to overcome tainted-blood fallout in search for donors

Canada''s lack of self-sufficiency in blood products has led to the opening of a blood-plasma collection centre in Thunder Bay, Ont.--the first of its type in Canada. In convincing donors to donate plasma, the new centre had to overcome some lingering public concern about the safety of the blood-collection system.     

Reye's syndrome: a clinical review.

Reye''s syndrome is a virus-associated biphasic disease that causes acute encephalopathy in infants and children. Epidemiologic and experimental data support the hypothesis that it is a multifactorial disease of modern civilization. Just as young patients seem to be recovering uneventfully from the first phase of the illness, usually a nonspecific viral-like illness such as a respiratory tract infection or gastroenteritis, the second phase, encephalopathy, starts unexpectedly, with vomiting and sensorial changes. Identifying the syndrome early ;in the second phase and referring the child to a specialized centre with the experience, staff and facilities to manage this phase has improved the numbers and neurologic condition of survivors, though the overall mortality is still about 20%. Therapy is primarily directed at facilitating adequate cerebral perfusion pressure.     

When Intuition is Not Enough. Why the Principle of Procreative Beneficence Must Work Much Harder to Justify Its Eugenic Vision

The Principle of Procreative Beneficence (PPB) claims that we have a moral obligation, where choice is possible, to choose to create the best child we can. The existence of this moral obligation has been proposed by John Harris and Julian Savulescu and has proved controversial on many levels, not least that it is eugenics, asking us to produce the best children we can, not for the sake of that child's welfare, but in order to make a better society. These are strong claims that require robust justification that can be open to scrutiny and debate. This article argues that robust justifications are currently lacking in the work of Savulescu and Harris. The justifications provided for their conclusions about this obligation to have the best child possible rely heavily on Derek Parfit's Non‐Identity Problem and the intuitive response this provokes in many of us. Unfortunately Harris and Savulescu do not embrace the entirety of the Non‐Identity Problem and the puzzle that it presents. The Non‐Identity Problem actually provides a refutation of PPB. In order to establish PPB as a credible and defendable principle, Harris and Savulescu need to find what has eluded Parfit and many others: a solution to the Non‐Identity Problem and thus an overturning of the refutation it provides for PPB. While Harris and Savulescu do hint at possible but highly problematic solutions to the Non‐Identity Problem, these are not developed or defended. As a result their controversial is left supported by little more than intuition.

Non-accidental injury in children: what we do in Derby.

A scheme for dealing with cases of non-accidental injury in children in the Derby clinical area has been operating since 1971. A stable team of doctors, policemen, and social workers deal with each case. The parents are told at once that battering is suspected, and the police and social services department co-operate closely in establishing the facts, supporting the family, and protecting the child. A psychiatric assessment of the parents may help social workers decide on the long-term care of the child, and the forensic physician is invaluable if the case has to go to court. The team has made three recommendations about prevention and management of these cases: a specialist social service team should be set up to deal with these children and regain the skills and knowledge lost when children''s departments were abolished in 1971; babies should be routinely weighed naked in infant welfare clinics; and juvenile courts should be able to order a psychiatric report on the parents in care proceedings.     

PROCREATIVE BENEFICENCE – CUI BONO?

Recently, Julian Savulescu and Guy Kahane have defended the Principle of Procreative Beneficence (PB), according to which prospective parents ought to select children with the view that their future child has ‘the best chance of the best life’. I argue that the arguments Savulescu and Kahane adduce in favour of PB equally well support what I call the Principle of General Procreative Beneficence (GPB). GPB states that couples ought to select children in view of maximizing the overall expected value in the world, not just the welfare of their future child. I further argue that Savulescu and Kahane's claim that PB has significantly more weight than competing moral principles, such as GPB, lacks justification. A possible argument for PB having significant weight builds on a principle of parental partiality towards one's own children. But this principle does not support PB; it supports a Principle of Sibling‐Oriented Procreative Beneficence (SPB), according to which parents selecting a child should maximize the benefit of all their children. Indeed, PB itself will in some cases be self‐effacing in favour of SPB.     

Neural Activity during Natural Viewing of Sesame Street Statistically Predicts Test Scores in Early Childhood

It is not currently possible to measure the real-world thought process that a child has while observing an actual school lesson. However, if it could be done, children''s neural processes would presumably be predictive of what they know. Such neural measures would shed new light on children''s real-world thought. Toward that goal, this study examines neural processes that are evoked naturalistically, during educational television viewing. Children and adults all watched the same Sesame Street video during functional magnetic resonance imaging (fMRI). Whole-brain intersubject correlations between the neural timeseries from each child and a group of adults were used to derive maps of “neural maturity” for children. Neural maturity in the intraparietal sulcus (IPS), a region with a known role in basic numerical cognition, predicted children''s formal mathematics abilities. In contrast, neural maturity in Broca''s area correlated with children''s verbal abilities, consistent with prior language research. Our data show that children''s neural responses while watching complex real-world stimuli predict their cognitive abilities in a content-specific manner. This more ecologically natural paradigm, combined with the novel measure of “neural maturity,” provides a new method for studying real-world mathematics development in the brain.     

Oxytocin shapes parental motion during father–infant interaction

An infant-oriented parental repertoire contributes to an infant''s development and well-being. The role of oxytocin (OT) in promoting affiliative bonds and parenting has been established in numerous animal and human studies. Recently, acute administration of OT to a parent was found to enhance the carer''s, but at the same time also the infant''s, physiological and behavioural readiness for dyadic social engagement. Yet, the exact cues that are involved in this affiliative transmission process remain unclear. The existing literature suggests that motion and vocalization are key social signals for the offspring that facilitates social participation, and that distance and motion perception are modulated by OT in humans. Here, we employed a computational method on video vignettes of human parent–infant interaction including 32 fathers that were administered OT or a placebo in a crossover experimental design. Results indicate that OT modulates parental proximity to the infant, as well as the father''s head speed and head acceleration but not the father''s vocalization during dyadic interaction. Similarly, the infant''s OT reactivity is positively correlated with father''s head acceleration. The current findings are the first to report a relationship between the OT system and parental motion characteristics, further suggesting that the cross-generation transmission of parenting in humans might be underlaid by nuanced, infant-oriented, gestures relating to the carer''s proximity, speed and acceleration within the dyadic context.     

Population ageing: what should we worry about?

Approximately half the world''s population now has replacement-level fertility or below. The UK experience in accommodating to a changing dependency ratio provides some generalizable insights. A mechanistic approach assuming a fixed retirement age and a need to raise fertility or increase immigration in order to maintain pensions at a fixed proportion of the gross domestic product (GDP) is overstated and wrong. It needs to be replaced by a welfare optimizing model, which takes into account the increasing years of healthy life, a slow rise in the pensionable age, capital inheritance and wider welfare considerations of population density that are not reflected in GDP measures. A combined replacement ratio (CRR) is suggested for developed countries combining the impact of the fertility rate and immigration rate. A CRR above 2 implies continued population growth. The current UK CRR of 2.48 is higher than needed for pension reasons, and it is suggested that it exceeds the welfare maximizing level.

Reliability of health information for the public on the World Wide Web: systematic survey of advice on managing fever in children at home.

OBJECTIVE: To assess the reliability of healthcare information on the world wide web and therefore how it may help lay people cope with common health problems. METHODS: Systematic search by means of two search engines, Yahoo and Excite, of parent oriented web pages relating to home management of feverish children. Reliability of information on the web sites was checked by comparison with published guidelines. MAIN OUTCOME MEASURES: Minimum temperature of child that should be considered as fever, optimal sites for measuring temperature, pharmacological and physical treatment of fever, conditions that may warrant a doctor''s visit. RESULTS: 41 web pages were retrieved and considered. 28 web pages gave a temperature above which a child is feverish; 26 pages indicated the optimal site for taking temperature, most recommending rectal measurement; 31 of the 34 pages that mentioned drug treatment recommended paracetamol as an antipyretic; 38 pages recommended non-drug measures, most commonly tepid sponging, dressing lightly, and increasing fluid intake; and 36 pages gave some indication of when a doctor should be called. Only four web pages adhered closely to the main recommendations in the guidelines. The largest deviations were in sponging procedures and how to take a child''s temperature, whereas there was a general agreement in the use of paracetamol. CONCLUSIONS: Only a few web sites provided complete and accurate information for this common and widely discussed condition. This suggests an urgent need to check public oriented healthcare information on the internet for accuracy, completeness, and consistency.
