山楂贮藏保鲜

山楂的耐藏性较好,但贮藏过程中,果实易失水而萎蔫;易受霉菌侵染而腐烂。因此,山楂贮藏要注意以下几个问题。 1 品种及栽培要求 1.1 品种 山楂的品种、品系较多,栽培地域较广,应选择大面积栽培的耐贮藏品种。 1.2 地域与气候的影响 山楂在我国分布极广,一般高纬度较寒冷的北方地区所产的山楂,比产于低纬度较温暖的南方山楂品种耐贮藏。 1.3 采摘期(成熟度)的影响 山楂采摘期的确定,往往要考虑到市场的需要、用途和耐贮藏性。一般用于长期贮藏的山楂,采收期可适当提前;用于鲜销和加工的山楂,则应适当晚些采收,其风味、产量都将相应提高。用于贮藏的山楂,采摘过晚,山楂大量落果,机械伤增加,果实采后很快衰老、变软、腐烂增多,耐藏性降低;采收过早,会导致果色、香、味等固有风味不足,影响产量和品质。     

X65管线钢在模拟海水环境中的腐蚀行为

采用失重法,SEM,扫描开尔文探针(SKP)技术等方法研究了X65管线钢在模拟海水环境中的腐蚀行为;采用电化学方法研究了温度、SO42-含量对X65管线钢在模拟海水环境中腐蚀行为的影响.结果表明:随着SO42-量的增加,腐蚀速率呈现增大的趋势;随着温度的升高,X65钢的自腐蚀电流密度增大,但增大的幅度却逐渐减小;随着浸泡时间的延长,X65钢的平均腐蚀速率呈现下降趋势,但局部腐蚀进一步加重且出现明显的点蚀现象.     

梨、苹果简易贮藏技巧

梨、苹果到了成熟期,应适时采摘,否则落果、烂果、裂果,致使丰产不能丰收。但采摘后一时又卖不掉,贮藏又无固定库房,这样可采取简易贮藏的方法,既可达到延长待销时间,又可达到保鲜增值的效果。笔者根据多年的生产实践总结,现介绍几种梨、苹果简易贮藏方法,供果农参考。一、土窖贮藏法。选择地下水位低,通风良好,排水通畅的地方挖土窖。一般挖深1米左右,宽2.4米,长4-6米(可根据所贮量及地方的长短而定)土窖,两侧贮放水果,中间留40厘米宽的走道(也可作排气通道),上面用芦苇或草苫覆盖防风遮阳。二、装箱贮藏法。在通风向阳的室内用塑料周转箱…     

盐酸介质中苯并咪唑阳离子表面活性剂对碳钢的缓蚀性能研究

文章利用失重法、极化曲线和SEM研究苯并咪唑阳离子表面活性剂GBCS12-3在1mol/L盐酸中对碳钢的缓蚀性能,结果表明:其对碳钢在盐酸介质中的缓蚀率随浓度的增大而增加,随温度的升高而下降;缓蚀剂GBCS12-3的加入阻碍了腐蚀反应的进行;极化曲线表明GBCS12-3是以抑制阴极反应为主的混合型缓蚀剂;通过SEM可以看到其在碳钢表面形成了致密的吸附膜。

解吸附时间对聚乳酸共混体系泡孔形貌的影响

研究了在超临界CO2发泡过程中解吸附时间对聚乳酸与丁二醇-己二酸-对苯二甲酸共聚酯(PBAT)的二元体系以及添加LAK粒子(硫酸盐)的三元体系泡孔形貌的影响。结果表明,随解吸附时间的延长,各材料平均泡孔尺寸均不同程度地增大,泡孔密度减小;PBAT引起了非均相成核,降低了Gibbs自由能,减小了PLA泡孔尺寸,增大了泡孔密度;LAK粒子引起了空穴非均相成核,效果则更为明显,尺寸最小,但刚泄压时CO2浓度最高,未能发泡。     

山梨酸和丙酸钙复合保鲜剂对延长苹果保鲜期的研究

目的：本文主要研究了山梨酸和丙酸钙复合保鲜剂对苹果的保鲜效果。方法：经山梨酸和丙酸钙复合液（山梨酸0．039％,丙酸钙0．131％）浸泡处理后的苹果与未经处理的苹果和市面上所用保鲜药液处理过的苹果相对比,在室温254-2℃,湿度为85％-90％条件下贮存,12周后测定其含酸量、可溶性糖含量及呼吸强度变化等指标。结果：苹果中各营养物质分别为：含酸量〉0．8％、可溶性糖含量〉22％、呼吸强度受抑制等,复合保鲜剂对苹果含酸量的下降、可溶性糖含量的下降及呼吸强度均有抑制作用。结论：复合保鲜剂在一定程度上防止了苹果内各种营养物质在贮运以及货架期的损失。     

Development in Information and Communications Technology (ICT) Statistics at the Australian Bureau of Statistics

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.     

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.     

Accountability of NGOs in Bangladesh A critical overview

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.     

Towards an Asian model of human resource management? A comparative analysis of China,Japan and South Korea

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.     

Ansätze und Ergebnisse anglo-amerikanischer M&A-Forschung

Based on a review of established U.S. management journals (1995–2003), six schools of thought are identified within the Anglo-American M&;A research: “Capital Market”, “Principal/Agent”, “Industrial Organization”, “Organizational Behavior”, “Human Resources” and “Strategic Management”. The literature review shows that the definition of M&;A success, the methods applied, and insights from empirical research differ according to the respective school of thought. Empirical studies focus on the resource combinations of merger partners, the specific circumstances of merger negotiations, and on integration management as antecedents of merger performance. Unfortunately, empirical findings have not yet provided reliable explanations for M&;A success. Based on the current state of Anglo-American M&;A research, the authors discuss implications for business practice, identify research gaps, and propose areas for future research.     

Introduction of New Technology with a Sound Transition of the Input-Output Structure

We examine the general equilibrium repercussions associated with the introduction of new technologies, using the generalized Leontief system that allows technological substitutions. We show that an untested introduction of cost-increasing technologies in any industry may result in creating a non-productive technological structure that does not satisfy the Hawkins-Simon condition, following the autonomous dynamic adjustment process with structural transitions in the economic system. Therefore, we propose a practicable control scheme of introducing cost-increasing technologies that strictly avoids the creation of non-productive structures in all periods of structural transition, using the available information on the ex ante technological structure.     

The Creation of the Office for National Statistics

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context.     

What helps? Women engineers' accounts of staying on

We have considerable understanding of the obstacles that women engineers encounter and the reasons that they leave the field, but we know less about what enables them to remain. Adopting an interpretivist approach, this article examines how a group of British women engineers in two FTSE 100 companies account for “staying on” in their male‐dominated work settings. We delineate four specific forms of help that facilitate women's retention in the field. We argue that exposure to help leads to women developing a habitus that enables them to continue working in engineering. To conclude, we draw on our findings to outline HR practices that will facilitate supportive relationships in the workplace and pave the way towards developing more positive organisational climates.
