中国食物可持续消费内涵及其实现路径

食物消费是人类赖以生存和发展的最基本的消费活动。践行食物可持续消费模式是构建绿色生活方式、建设生态文明的必然要求。目前中国居民食物消费领域呈现出膳食结构变化大、消费方式多元化等特征,同时存在不合理消费带来的健康隐患、食物浪费严重以及食品安全事件频发等诸多问题,严重制约了中国食物消费的可持续发展。文章探讨了食物可持续消费的定义、原则、特征及其相关概念的辨析,进一步提出了现阶段中国食物可持续消费的实现路径,即立足中国实际,从制度设计、方案制定、示范推广、科普引导和监测评估五个步骤着手构建食物可持续消费模式。本文研究结论指出应当重点关注大中城市和贫困农村等重点区域,并聚焦流动人口和中小学生等重点人群,在居民家庭和餐饮行业等重点领域优先探索构建食物可持续消费模式。     

三峡库区百万城、乡移民体育消费调查与对比研究

采用问卷调查、实地访问、文献资料调研等方法 ,对重庆市所辖库区 10 3万城、乡移民可支配收入、生活消费性支出与构成、体育消费结构及其影响因素等进行全方位调查研究。结果显示 :库区城市移民经济生活已步入小康水平 ,部分乡村移民还在贫困与温饱线上挣扎 ;库区城乡移民体育消费仍处于较低水平 ,体育消费以实物消费为主 ;制约库区域、乡移民体育消费的主要因素为文化素质、经济支付能力、时间、体育场地等。旨在为有关职能部门了解、制定完善库区移民体育发展的对策提供理论依据     

Comparison of visual,automatic and semiautomatic methods to determine ventilatory indices in 50 to 60 years old adults

ABSTRACT

The aim of this study was to compare different methods of detecting ventilatory indices (VI) and to investigate the impact of cardiorespiratory fitness (CRF) level on VI detection. Fifty females and fifty males completed a graded exercise test until volitional exhaustion with continuous gas-exchange measurement. The first and second ventilatory indices (VI-1, VI-2) were detected through different single automatic methods and through a semiautomatic method which combines visual and automatic detection methods. Additionally, the VIs were detected visually by two experts which served as the study specific gold standard. When comparing the semiautomatic method at VI-1 (intraclass correlation coefficients (ICC) 0.88 [0.81, 0.92], Bland-Altman bias ± limits of agreement (LoA) 55 ± 334 ml O₂ · min^?1) and VI-2 (ICC 0.97 [0.96, 0.98], LoA 1 ± 268 ml O₂ · min^?1) to the visually detected VI, high levels of agreements and no significant differences were found. This was not the case for any of the other automatic methods. Additionally, we couldn’t find any relevant differences regarding the CRF level.

We therefore concluded that the semiautomatic detection method should be used for VI detection, as results are more accurate than in any of the single-automatic methods.

Abbreviations: CPET: cardiopulmonary exercise test; CRF: Cardiorespiratory fitness; VO_2peak: peak oxygen uptake; VI-1: first ventilatory indices; VI-2: second ventilatory indices; LoA: Bland-Altman bias ± limits of agreement; ICC: intraclass correlation coefficient.     

A new instrument for measuring pre-service biology teachers' pedagogical content knowledge: The PCK-IBI

Teachers' pedagogical content knowledge (PCK) is highly important for effective design and implementation of school teaching. Thus, the current status, development and efficacy of this knowledge, its relationships with teaching quality parameters, and its impact on students' learning processes and success, require rigorous examination. Thoroughly validated, objective and reliable test instruments that are highly sensitive to changes in variables of proven knowledge-related relevance in teacher education are also required. Previous attempts to design such instruments for assessing science teachers' PCK have largely focused on mathematical content. Therefore, here we present an instrument (the pedagogical content knowledge in biology inventory, PCK-IBI), based on conceptualizations of teachers' professional competence, for assessing secondary school pre-service biology teachers' PCK. In a series of three evaluations and refinements it was tested with samples of N = 274 and N = 432 German pre-service as well as one sample of n = 65 German pre-service and n = 35 German in-service biology teachers. Item analysis, scale analysis and empirically obtained indicators of validity suggest that the final 34-item-version of the PCK-IBI is unidimensional, provides objective test scores and enables reliable and valid registration of pre-service biology teachers' PCK. Thus, hypotheses regarding specific aspects of the model on which the PCK-IBI's construction is based on are empirically supported. The results of our study provide empirical support for the instrument's potential utility.     

A sudden creatinine increase: A case report

Creatinine and estimated glomerular filtration rate (eGFR) are first-line laboratory parameters in the diagnosis of various renal diseases. In recent decades, cystatin C (cysC) has furthered the laboratory repertoire regarding renal status assessment and has been implemented in many clinical guidelines. Accordingly, with the establishment of cysC as a renal routine biomarker, further opportunities for assessing eGFR have been attained. Nevertheless, various limitations are still associated with cysC and creatinine analysis. Preanalytical errors could cause false results in both biomarkers. In our case, we were confronted with implausibly elevated creatinine levels due to preanalytical errors.     

Marketing of services in secondary schools in the Republic of Croatia

The goals of the research were to determine the quantity, variety and quality of service, the extent to which certain marketing activities are applied in Croatian high schools, to explore the attitudes of teachers in respect to the need for marketing activity application in secondary schools in Croatia, and the knowledge teachers have about the marketing of services. In order to achieve these goals, we conducted a survey including 271 teachers of public, private and religious high schools. Even though the research confirmed that all schools apply numerous marketing activities, teachers in religious (85%) and public (72%) high schools believe these activities are not present at all. Teachers in public (26%) and religious (48%) high schools share the opinion that marketing activities should not be applied since they work in non-profit institutions. This opinion indicates a lack of knowledge about marketing and even a wrong attitude toward it.
