民用飞机飞行试验项目管理研究

对于民用飞机飞行试验的开展,我国尚处于起步和探索阶段。通过对多年的民机试飞规律进行研究,对试飞组织的项目管理进行总结和归纳,把项目管理的核心内容分解为架次管理、科目管理和飞机管理,同时创新性的提出"计划-实施-管理-计划"的闭环管理理论,为提高民用飞机飞行试验项目管理效率和组织实施能力铺垫理论基础。

“十五”期间我国将重点生产支线飞机

一、中国民用飞机工业发展的简要回顾中国的航空工业创建于20世纪50年代初。在近50年的时间里,中国的民用飞机工业先后研制生产了8大系列、30多种机型货运飞机、旅客机和通用飞机。1957年,中国成功制造了运五飞机;60年代又开始研制运七和运八运输机,并进行了系列化发展;70年代以来,中国先后研制了运十、运十一、运十二和农林五 A 飞机。其中,运七系列飞机至今已安全飞行了70万小时、70万起落。在运七飞机的基础上开发研制的新舟60飞机,基本达到了国际同类涡浆飞机的水     

新型通用型飞机颤振试验装置研发成功 等

由中国空气动力研究与发展中心低速所与俄罗斯中央流体力学研究院共同研发的新型飞机颤振试验装置，近日安装调试完成，验证试验获得成功。这套我国最先进飞机颤振试验装置的研发成功，为进一步拓展和提升我国开展飞机颤振试验的范围和能力提供了技术支撑。飞机在飞行速度太快时，经常会诱发颤振，如果不及时有效地控制飞机，最终会导致飞机解体。多年来，该所曾做过多期飞机颤振试验，经过一年多终于成功研发出这套新装置，并已在低速风洞列装，为试验效力。这套飞机颤振装置，通用性强，既适用于战斗机，又可用于民用飞机的颤振试验研究，强度、刚度、固有频率等技术指标完全满足试验要求。（科技部网）     

陕西民用飞机生产应当有一个新的更大的发展

<正> 近两年来,陕西民用飞机的生产有了新的发展,取得了一些重要经验,同时也存在着一些亟待解决的问题。民用飞机的生产今后要有一个新的更大的发展,还需要做许多扎实细致的工作。陕西生产的“运七”、“运八”飞机,是六十年代末开始测绘仿制的,分别在1970年底和1974年底首次试飞成功,此后形成生产能力,于1984年交付民航营运。民用飞机投入民航营运后,大大加快了研制和生产步伐。生产“运八”飞机的西安飞机制造公司1986年与国家民航总局签订了“七五”期间认购协议和

美欧大飞机补贴争端

案例简介 大飞机的生产曾由美国公司高度垄断，到上世纪90年代欧洲大飞机横空出世后，逐步呈现出波音和空客双寡头垄断的格局和此消彼长的竞争态势。波音公司成立于1916年，初期以生产军用飞机为主，60年代以后主要业务转向民用飞机，发展了波音7x7系列型号，1997年收购世界航空制造业排名第三的麦道，逐步成为当时全球最主要的商用飞机制造商。     

Penetration and Post-infection Development of Meloidogyne Incognita on Tobacco as Treated by Rhizobacteria Pseudomonas Fluorescens Strain P-72-10

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction.     

For Better or for Worse? Local Impacts of the Decentralization of Indonesia’s Forest Sector

This paper quantifies the local impacts of mechanized logging on forest-dependent communities in Indonesia, before and after decentralization. A conceptual framework incorporates financial, social, enforcement, rent-seeking, and environmental impacts. Using data from 60 communities in East Kalimantan, the empirical results suggest that significantly more households received financial and in-kind benefits after decentralization compared to before. Many communities engaged in self-enforcement activities against firms both before and after decentralization. Post-decentralization, a significantly higher proportion of households perceived community forest ownership. There were few significant differences in perceived environmental impacts. Little evidence exists of a post-decentralization trade-off between environmental and financial contractual provisions.

Markteintrittstiming von Telekommunikationsdiensteanbietern

Zusammenfassung Die vorliegende Studie analysiert für 87 Neuprodukteinführungen (NPE) und Auslandsmarkteintritte (AME) von Telekommunikations(TK)-Diensteanbietern in Deutschland, zu denen 42 Schlüsselinformanten in einer schriftlichen Befragung Auskunft gaben, (1) inwieweit deren zeitliche Eintrittspositionierung durch Marktcharakteristika und Unternehmensressourcen erkl?rbar ist sowie (2) inwieweit und gegebenenfalls unter welchen unternehmensexternen und -internen Situationsbedingungen deren Markteintrittstiming mit dem wahrgenommenen Eintrittserfolg assoziiert ist. Ein früher Markteintritt wurde dann realisiert, wenn die Wettbewerbsintensit?t im adressierten Gesch?ft niedrig und das Budget für den Expansionsschritt überdurchschnittlich ausfielen. Zwischen dem Markteintrittstiming und der Beurteilung des Eintrittserfolgs bestand ein nicht monotoner, umgekehrt U-f?rmiger Zusammenhang: Frühe Folger wiesen signifikant bessere Erfolgswerte auf als Pioniere und sp?te Folger, deren Erfolgsniveaus nicht signifikant divergierten. In einer Industrie, die durch starke externe Netzeffekte gepr?gt ist, fallen offenbar die Nachteile eines Markteintritts als Pionier oder sp?ter Folger st?rker ins Gewicht als die Vorteile dieser beiden zeitlichen Eintrittspositionierungen. Unabh?ngig vom Markteintrittstiming wurden NPE/AME von TK-Unternehmen als erfolgreicher eingestuft, wenn sie sich in einen Markt mit stark wachsender Nachfrage und aufeinander abgestimmt (re)agierenden Wettbewerbern mit qualitativ überdurchschnittlichen, abw?rtskompatiblen, erprobbaren und wenig erkl?rungsbedürftigen TK-Diensten engagierten.

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.     

The causes of Japan's ‘lost decade’: The role of household consumption

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important.
