浅论管理的科学性与艺术性

管理的本质是什么？这一直是困扰管理学界十分头疼的问题，一些知名学者甚至管理大师在这个问题上也意见相左。科学的本质特征是可证伪性。但是，我们对管科管理学科公认背景知识的历史形成进行分析，发现这样一个事实：管理作为科学，竟然无法证伪。为了解决这管理学科中的局限性，当前理论界把管理科学所不能解释的问题统归于管理的艺术性，认为管理既是科学又是艺术，二者不能割裂，就像一件事物的两面，二者相互依赖、相互影响、相互促进和相互补充。因此，管理的艺术性是对管理科学局限性的修正。

浅谈我国户籍制度改革

将城市居民和农村居民区别对待的二元户籍制度是我国计划经济遗留的产物，随着我国城市化和现代化的发展，这种二元户籍制度导致农村劳动力不能顺利转移，已成为制约农业发展的瓶颈。改变目前这种户籍制度，转移农村的剩余劳动力，消除城市居民和农村居民的差别，加速我国城市化进程，是目前我国加速发展农业不能回避并且亟待解决的问题。

把握住自己

公安部制定、颁布的“五条禁令”，是规范公安民警行为的一条不可逾越的红线。公安队伍是一支具有武装性质的队伍，如果没有铁的纪律作保证，就很难树立良好的形象，更难以做到让党和政府放心、让人民满意。“五条禁令”是对公安民警最基本、最起码的要求，主要是解决公安队伍中存在的突出问题，并不能完全解决公安队伍中存在的所有问题。     

发展林纸业 提高湖区环境质量和人民生活质量─—在洞庭湖综合治理与林纸经营一体化主题研讨会上的讲话

尊敬的各部门领导和专家：郑茂清副省长原计划参加今天的会议，他有个讲话已发给大家。但今天省里临时有个重要会议，他就不能出席今天这个会议了。在此，我代表省政府对各位领导和专家来参加这个会议，到湖南来指导工作，表示热烈的欢迎和衷心的感谢。希望这次会议要开好，更重要的是会议的成果要落实好，洞庭湖综合治理和林纸经营一体化是当前经济发展必须解决的问题。中国现在人均纸消耗量是不高的，随着我国经济的发展和人民生活水平的提高，纸消耗必然会逐渐增长，纸的生产消耗必然要原材料，但原材料的供应又不能以牺牲环境为代价。把…     

政策是林业持久发展的不竭动力

我国是一个缺材少林国家，目前林业的发展远远不能适应国民经济和社会发展的要求，不能满足人民生活水平日益提高的要求。着力增加森林资源，加快林业改革步伐，进而实现林业的跨越式发展，是关系当前我国生态环境建设和经济社会可持续发展的一件大事。要实现这个目标，有必要在以下几个方面探讨林业发展中的一些深层次政策问颖。 （一）关于着力推进林业分类经营战略的问题。对林业进行分类经营、分区指导己经有六七年了。现在看，分类经营仍是新世纪林业政策的一次重大调整，是事关林业长远发展的一项根本性改革。实行分类经营，就是要按…     

关于我国绿化的几个问题──在政协第九届全国委员会常务委员会第六次会议闭幕会上的讲话(摘要)

这次会议的主题是环境与发展。会议期间，大家以负责、求实的精神，发表了许多很好的意见和建议。研究环境与发展，不能不涉及绿化问题，对绿化问题，人们一直比较关心，我也作过一些思考。借此机会，谈点看法。绿化，特别是植树造林，对于人类居住环境的保护和改善，对于人类自身的生存和发展，有着极为重要的意义。森林是陆地生态系统的主体，对保持水土、涵养水源、调节气候、净化空气、防风固沙、养护物种具有不可替代的作用。森林是发展经济、改善人民生活的重要基础，能提供人们所需要的木材、食品。药品、燃料及工业原料。人类不能离…

Persistence of herbicides in forest nursery soils

The persistence of the four herbicides atrazine, hexazinone, lenacil and linuron was studied in forest nursery soils. The adsorption capacities of the soils for the chemicals were described by the distribution coefficients kj and k_oc. Due to the low content of organic matter in the soils the k_a‐values were low, in several cases being <1 for hexazinone. Hexazinone also had the lowest k _oc‐value (30) while the other substances had k_oc ‐values within the range 200–400. In some cases hexazinone showed great mobility under field conditions. The formula c=c_o‐kt^1/2 was used to describe the disappearance of the herbicides from the various soils. The rate of degradation of the four herbicides correlated well with the rate of respiration in the same soils in laboratory experiments, and for linuron reasonably well also in field experiments. In the field experiments the herbicides penetrated the top soil layer. In the subsoil the risk of further transport downward to the drainage system or ground water increased, especially for hexazinone. Linuron as well as the fungicides maneb and tolylfluanid suppressed the decomposition rate of hexazinone in laboratory experiments.

Log sawing positioning optimization and log bucking of tropical hardwood species to increase the volume yield

The sawmill industry is a very important link in the Mozambique forest products value chain, but the industry is characterized by undeveloped processing technology and high-volume export of almost unrefined logs. The low volume yield of sawn timber has been identified as a critical gap in the technological development of the industry. To improve the profitability of the industry, there is thus a need to develop methods and techniques that improve the yield. In this paper, different positioning of logs prior to sawing and the possibility of increasing the volume yield of crooked logs by bucking the logs before sawing have been studied. A computer simulation was used to study the cant-sawing and through-and-through sawing of the logs to determine the volume yield of sawn timber from the jambirre (Millettia stuhlmannii Taub.) and umbila (Pterocarpus angolensis DC.) species. The optimal position, i.e. the position of the log before sawing that gives the highest volume yield of sawn timber for a given sawing pattern when the positioning parameters, offset, skew and rotation, are considered gave a considerable higher volume yield than the horns-down position. By bucking very crooked logs and using the horns-down positioning before sawing, the volume yield can be of the same magnitude as that obtained by optimal positioning on full-length (un-bucked) logs. The bucking reduces the crook of the logs and hence increases the volume yield of sawn timber.     

Serological marking of <Emphasis Type="Italic">Pnigalio agraules</Emphasis> (Hymenoptera: Eulophidae) for field dispersal studies

The parasitoid wasp Pnigalio agraules (Wlk.) is a key natural enemy of the horsechestnut leafminer Cameraria ohridella Deschka and Dimić (Lepidoptera: Gracillariidae). As a basis for mark-release-recapture studies, aimed at investigating the dispersal of this parasitoid in the field, adults of P. agraules were marked using a vertebrate-specific immunoglobulin (IgG). The marker was later detected by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA). The IgG was either applied externally by spraying or internally by feeding an IgG-enriched diet. Different concentrations of the marker were used and the influence of abiotic (climatic conditions, time elapsed between marking and marker examination) and biotic factors (sex and age of the parasitoids) on the detection of the immunomarker was tested. External marking by spraying led to more homogeneous labelling than feeding the marker. Parasitoids labelled with 0.25 mg rabbit IgG per ten individuals contained enough immunomarker to be easily distinguished from unmarked ones. Neither the climatic conditions nor the sex or age of the insects had an influence on the detection of the marker. The IgG remained well detectable during the entire lifespan of the parasitoids, which was not negatively affected by the marking procedure. Serological marking can be used to investigate the dispersal behaviour of beneficial insects within mark-release-recapture studies.

An evaluation of the Acacia albida-based agroforestry practices in the Hararghe highlands of Eastern Ethiopia

Growing Acacia albida as a permanent tree crop, on farmlands with cereals, vegetables and coffee underneath or in between, is an indigenous agroforestry system in the Hararghe highlands of Eastern Ethiopia. However, there is practically no systematic record or data on the merits and benefits of this practice.The paper presents the results of an investigation into the effects of the presence of A. albida on farmlands on the yield of maize (Zea mays L.) and sorghum (Sorghum bicolor L. Moench). Twenty seven plot pairs each consisting of one plot underneath the A. albida foliage cover and the other in the open, away from the tree-on farmers' fields, in a 40 km radius around the Alemaya College of Agriculture, were sampled and the yield components analyzed. A statistically significant increase in crops yields by 56% on average was found for the crops under the tree canopies compared to those away from the trees. This increase was caused by the improvement in 1000 grain weight and number of grains of plants under the tree, indicating that the trees enhanced the fertility status of the soil and improved its physical conditions in terms of crop growth.Additional benefits from the A. albida trees include supply of fuelwood and fodder. Quantitative estimates of these outputs as well as their monetary values are presented in the paper. However, in order to realize these benefits to a discernible extent, higher stand densities of the tree than at present are required.Based on an enquiry about the farmers attitude towards A. albida, the prospects for an extension of this promising agroforestry technique are discussed against the background of the state and trends of development of agriculture in the area. It is surmised that despite some shortcomings like the relatively slow and highly variable growth of A. albida and a conflict with the spreading cultivation of Ch'at (Catha edulis Forsk.), the prospects of extension of this technique are good. It is recommended that its propagation should be incorporated into the programmes of the extension agencies of the various governmental agencies concerned with land use.
