大学生健康关注度与健康行为相关性研究

采用文献资料法、问卷调查法,探讨大学生对健康的关注度和健康行为之间的关系.结果显示,健康认知,健康有关活动的限制和健康行为(如暴饮暴食,睡眠质量和体育锻炼)都与意念问卷(FFMQ)相关,且压力在一定程度上介入影响.结论:关注度与减压有一定关系,同时缓解压力又有助于促进积极的健康意识和行为.     

Natural history and behaviour of the primitively eusocial wasp Ropalidia marginata (Hymenoptera: Vespidae): a comparison of the two sexes

We report the natural history and behaviour of the primitively eusocial wasp Ropalidia marginata with a special reference to the males. We found that just as nests of this species are found throughout the year, so are the males. Females spend all their life in their nests but males stay in their natal nests only for 1–12 days and leave to lead a nomadic life. Males maintained in the laboratory can live for up to 140 days. Like all eusocial hymenopteran males, R. marginata males also do not perform any colony maintenance activities. We found that males did not forage or feed larvae. Compared with females, males showed fewer dominance and subordinate behaviours and being solicited behaviour and more feeding self and soliciting behaviours. By comparing males with young females, we found similar differences, except that the males showed similar rates of feeding self and higher rates of subordinate behaviour.     

The life‐cycle of Hemigalichus chrotogale sp. nov. (Acari: Listrophoridae), with comparative observations on listrophorid morphology

A new fur‐mite species, Hemigalichus chrotogale (Acari: Listrophoridae), is described from Chrotogale owstoni (Carnivora: Viverridae) from Vietnam. The external morphology of all instars is described in detail. The precopulatory mate‐guarding behaviour exhibited by H. chrotogale is the first report of this phenomenon in the Listrophoridae. A morphological comparison of all currently recognized listrophorid genera and some early derivative representatives of the family Atopomelidae, which are closely allied to the Listrophoridae, is conducted. The results obtained support the monophyly of Listrophoridae. The family Listrophoridae includes two subfamilies, Listrophorinae, with more than 150 species in 20 genera, and the monobasic Aplodontochirinae, and is characterized by the following synapomorphies: the palps are enveloped by distinct membranes, the prescapular shield covers the gnathosoma, or most of it, dorsally, the clasping organs of coxal fields I are larger than those of coxal fields II, and setae scx, baI–II, pRII, and sIII are absent.     

Natural history of Phyllomedusa megacephala (Miranda-Ribeiro, 1926) (Anura: Hylidae) in southeastern Brazil,with descriptions of its breeding biology and male territorial behaviour

The breeding biology and male territorial behaviour of the large-headed leaf-frog (Phyllomedusa megacephala) were studied in three temporary altitudinal streams located in the Cerrado biome of southeastern Brazil, during three consecutive years (2007–2009). Phyllomedusa megacephala showed significant sexual dimorphism, with females being bigger and heavier than males. Acoustic and physical interactions between males defending or not defending territories including amplectant and non-amplectant males, patrolling behaviour by males without established territories, and triple amplexus were observed. Neither males nor females were observed using visual cues when searching for mates. We found that males that were present at breeding sites in previous years bred more successfully and maintained territory better.     

高职学生余暇体育行为与体育教学服务的研究

通过问卷法、访问法对广东高职院校学生的余暇体育锻炼行为进行调查和对高职高专体育教师的访问,了解学校体育教学为学生余暇体育行为服务的现状,结果发现：现阶段只有42.5%的学生用于余暇体育锻炼的运动项目是在体育教学课程上学会的.因此,如何提高体育教学对学生余暇体育锻炼行为的服务,是突出体育教育培养学生＂身体健康、心理健康、社会适应能力＂的全面和谐发展.     

Morphology and feeding behaviour of the leaf-mining larva of Cheilosia semifasciata (Diptera: Syrphidae)

In North Wales the larva of Cheilosia semifasciata (Diptera: Syrphidae) makes full-depth blotch mines in leaves of Umbilicus rupestris. Mines occur mostly on shaded plants with one larva per plant. Each larva mines several leaves to complete development and initiates new mines by curling round the leaf margin and puncturing the epidermis under the leaf. Unlike other dipteran leaf-miners which feed on their sides, only the thorax is turned sideways when feeding. The larva uses a grasping organ on the anal segment to grip the substrate when moving externally on the food-plant. Inside leaf mines, position is further secured by the integumental vestiture which grips the epidermis above the larva. The morphology and behaviour of the larva of C. semifasciata differs markedly from larvae of three congeneric species that tunnel in stems and roots.     

英、澳等国数学教学监测表的研究及启示

科学监测教师的教学行为对于提高教师的教学质量具有积极的促进作用。近年来,英、澳等国研究开发的数学教学监测表（ToMOS）就是通过对于数学课堂上具体教学行为的监测和记录,为教师提供一个反思教学、提高教学质量的有用工具。该监测表的研究与利用给我们以有益的启示。
