Turnover Causation Amongst High School Teachers in Nigeria

Four theoretical frameworks were used to explore causations of turnover amongst high school teachers in Nigeria: (1) teachers’ personal health, (2) work–family life, (3) job satisfaction, and (4) actual turnover intention. Quantitative data were obtained from 925 public high school teachers in Ogun State, South-Western Nigeria. Cronbach's Alpha reliability procedure, regression modelling and t-test were used to analyse a total of 96 causations of turnover. Ad hoc analysis returned an Alpha value of 0.78. However, this improved to 0.93 when the causation factors were reduced to 64 – those with highest item-rest and itemtotal correlations. The findings showed that job (dis)satisfaction, personal health and work– family life conflict are prominent amongst the issues that trigger the intention of Nigerian high school teachers to quit their jobs voluntarily. Insights from the findings will help funding administrators in prioritising strategic decisions around mitigating turnover.     

疏通新建本科院校教学质量提高的瓶颈——以厦门理工学院为例

高等教育从"精英"阶段进入到"大众化"阶段以来,一大批新建本科院校在快速发展的同时,暴露出影响学校持续发展的关键师资问题,尤其是青年教师教学能力和素质水平的高低直接影响到人才培养质量。本文以厦门理工学院为例分析了新建本科院校在快速发展中的教师教学能力培养方面的问题,并有针对性地提出相应的对策。     

强化应用数学意识,提高数学应用能力

数学是一门应用的艺术,运用数学知识解决实际问题是我们学数学的重要目的之一。数学教学的关键是教会学生用所学的知识解决实际问题,即要提高学生的应用知识的能力,而目前,大部分学生应用意识薄,应用能力弱。长此以往,必将学而无用,适应不了社会发展的需要。因此培养学生的数学应用意识,提高学生应用数学知识解决问题的能力,在数学教育中尤为重要。本文作者阐述了两个方面的内容：一是强化应用数学意识;二是提高数学应用能力。     

法国教师教育的改革现状及其借鉴

法国于1989年着手立法并全面革新师资培养的体制,以推动中小学教师合流及师资培育管道多元化的新制。教师培训学院（les instituts universitaires de formation des maltres,简称IUFM）于1991年诞生。随着教师培训学院的建立,到2005年提出将教师培训学院并入大学,再到2010年末起正式推动实施教师资格硕士化方案,这20年来法国教师教育经历了一场制度上和教育上的变革。     

城市农民工就业培训问题实证研究——基于对江苏省常州市302位农民工的调查与分析

根据302份调查问卷数据,具体分析农民工入城就业情况与参与技术培训情况,结果显示,城市农民工就业情况堪忧,参与职业技术培训比率低,效果差。他们期待由政府和企业承担培训费用,渴盼以短期、休息时间为主,采取在职学习和现场学习等教学模式,期望除了就业单位培训外,还对政府行为寄予厚望。因此,有关部门应完善农民工就业促进机制,建立农民工职业技术培训长效机制。     

现代汉语二合复句中分句语气异类组配的倾向性研究

现代汉语二合复句内分句语气同类组配是主体,异类组配是次要的。前后分句语气异类组配的使用频率具有一定的倾向性：陈述与疑问／祈使／感叹的组配〉疑问／祈使／感叹之间的两两组配;陈述＋疑问／祈使／感叹〉疑问／祈使／感叹＋陈述。陈述语气与疑问／祈使／感叹共享特征的数量都多于疑问、祈使、感叹两两语气之间共享特征的数量,因此前者是优势组配。疑问／祈使／感叹居前时通常要满足三个条件,居后时不受此限制,因此疑问／祈使／感叹居后是优势组配。     

Equatorial aurora: the aurora-like airglow in the negative magnetic anomaly

The most fantastic optical phenomena in the Earth''s upper atmosphere are the auroras. They are highly informative indicators of solar activity, geomagnetic activity, upper atmospheric structures and dynamics, and magnetospheric energetic particles. An area where the geomagnetic field differs significantly from the expected symmetric dipole, such as at the South Atlantic Anomaly, where the magnetic field intensity is low, gives rise to stronger precipitation of energetic particles into the upper atmosphere. Impact excitation and the subsequent airglow emissions exhibit aurora-like dynamic signatures. Nomenclatures of nonpolar aurora or equatorial auroras are similar to those used with the polar auroras owing to their similar excitation mechanisms. This paper provides an overview of the knowledge and the challenges concerning auroral activity at the South Atlantic Anomaly, or more generally, at the negative magnetic anomaly. We emphasize systematic investigation of the equatorial auroras to reveal the temporal and spatial evolution of the magnetic anomaly and the behaviour of energetic particles in near-Earth space.     

New physics searches at the BESIII experiment

The standard model (SM) of particle physics, comprised of the unified electroweak and quantum chromodynamic theories, accurately explains almost all experimental results related to the micro-world, and has made a number of predictions for previously unseen particles, most notably the Higgs scalar boson, that were subsequently discovered. As a result, the SM is currently universally accepted as the theory of the fundamental particles and their interactions. However, in spite of its numerous successes, the SM has a number of apparent shortcomings, including: many free parameters that must be supplied by experimental measurements; no mechanism to produce the dominance of matter over antimatter in the universe; and no explanations for gravity, the dark matter in the universe, neutrino masses, the number of particle generations, etc. Because of these shortcomings, there is considerable incentive to search for evidence for new, non-SM physics phenomena that might provide important clues about what a new, beyond the SM theory (BSM) might look like. Although the center-of-mass energies that BESIII can access are far below the energy frontier, searches for new, BSM physics are an important component of its research program. This report reviews some of the highlights from BESIII’s searches for signs of new, BSM physics by: measuring rates for processes that the SM predicts to be forbidden or very rare; searching for non-SM particles such as dark photons; performing precision tests of SM predictions; and looking for violations of the discrete symmetries C and CP in processes for which the SM expectations are immeasurably small.     

The biomechanical characteristics of high-performance endurance running

The biomechanical profile of high-level endurance runners may represent a useful model that could be used for developing training programmes designed to improve running style. This study, therefore, sought to compare the biomechanical characteristics of high-performance and recreational runners. Kinematic and kinetic measurements were taken during overground running from a cohort of 14 high-performance (8 male) and 14 recreational (8 male) runners, at four speeds ranging from 3.3 to 5.6?m?s^?1. Two-way ANOVA analysis was then used to explore group and speed effects and principal component analysis used to explore the interdependence of the tested variables. The data showed the high-performance runners to have a gait style characterised by an increased vertical velocity of the centre of mass and a flight time that was 11% longer than the recreational group. The high-performance group were also observed to adopt a forefoot strike pattern, to contact the ground with their foot closer to their body and to have a larger ankle moment. Importantly, although observed group differences were mostly independent of speed, the tested variables showed a high degree of interdependence suggesting an underlying unitary phenomenon. This is the first study to compare high-performance and recreational runners across a full range of kinematic and kinetic variables. The results suggest that high-performance runners maintain stride length with a prolonged aerial phase, rather than by landing with a more extended knee. These findings motivate future intervention studies that should investigate whether recreational runners could benefit from instruction to decrease shank inclination at foot contact.
