家庭小规模经营的局限性与农业组织形式再创新

农业家庭小规模经营不利农业机械的应用;不利于劳动生产率的提高;不利于实现技术进步基础上的扩大再生产和结构调整;最终表现为不利于农民收入的增长。克服家庭小规模经营局限性的出路在于组织形式的创新;实现这种创新需要相应的配套改革,调整农民进城的相关制度,完善和调整农村土地承包制度。     

欠发达地区农村养老模式探析——衢州市枫村花村养老的经验研究

家庭养老在欠发达地区的农村已经弱化,主要原因是社会变迁、社会流动、社会竞争和家庭结构的变化;社区养老的覆盖面太窄,发挥作用小;社会化养老还存在着接受的问题。该地区农村养老面临严峻的挑战。     

应对人口老龄化——对“接力”模式和“反哺”模式的再思考

在养老方式研究领域流行着这样一种观点:我国养老方式为双向的“反哺”模式,西方为单向的“接力”模式。笔者通过对最新的国内外文献研究发现,由于现实条件发生了重大改变,以上的有关国内外养老方式的划分方法已经不能准确地概括现实情况。从代际关系角度看,中西方养老方式没有本质的区别,用“相互依存模式”代替“反哺”和“接力”更能准确地反映养老方式的实质。     

国家综合配套改革试验区——区域经济发展的新模式探索

经过28年的改革开放,我国的经济体制改革已经进入攻坚阶段,改革的复杂性、艰巨性和风险性大大增强.经济领域内部各项改革的推进需要其他各项改革相配套,因此,改革的路径需要从单方面改革向综合配套改革转变。在这种形势下,国家综合配套改革试验区应运而生。这就需要从国家综合配套改革试验区的内涵和特征以及对区域经济发展的作用、机理以及政策建议等问题展开探讨。     

改革开放以来农村五保供养制度模式变迁探析

改革开放以来,我国农村五保供养制度随着农村经济体制改革深化和社会的变迁,与时俱进,在改革中发展,目前基本实现了从农民集体内部互助共济的传统救助模式,到以国家财政供养为主,集体保障、土地保障和社会帮扶为辅的现代社会保障模式的历史性变革。2006年新《农村五保供养工作条例》的出台,不仅标志着我国五保供养工作进入了规范化、法制化管理的新阶段,而且也标志着与社会主义市场经济体制相适应的新型农村五保供养制度的基本确立。     

论我国买方市场条件下经济结构的战略性调整

在我国当前特殊的经济环境下形成的买方市场，不同于西方发达国家的买方市场，具有典型的经济过剩特征。它的出现标志着我国经济发展到了一个关键阶段，经济结构的调整已经十分突出地摆在了我们面前，加大经济结构调整的力度是加快我国经济发展的关键一环。     

浅议当前农村养老保障体系中的缺陷和问题

目前农村家庭养老矛盾重重 ,面临农村养老保障由家庭养老向社会养老逐渐过渡的问题。在统筹社会养老基金时 ,应考虑农村养老保障体制转换成本问题 ,应由集体经济和国家负担部分转换成本。家庭养老以精神激励为主 ,但也要实行有效的监督。社会养老基金统筹可采用浮动制的收费办法 ,以弥补保费收缴水平偏低的矛盾     

Methodological decisions and the evaluation of possible effects of different family structures on children: The new family structures survey (NFSS)

Every social science researcher must make a number of methodological decisions when planning and implementing research projects. Each such decision carries with it both advantages and limitations. The decisions faced and made by Regnerus (2012) are discussed here in the wider context of social science literature regarding same-sex parenting. Even though the apparent outcomes of Regnerus’s study were unpopular, the methodological decisions he made in the design and implementation of the New Family Structures Survey were not uncommon among social scientists, including many progressive, gay and lesbian scholars. These decisions and the research they produced deserve considerable and continued discussion, but criticisms of the underlying ethics and professionalism are misplaced because nearly every methodological decision that was made has ample precedents in research published by many other credible and distinguished scholars.     

Sri Lanka: an exploration of the systemic erosion of stability

Abstract

In Sri Lanka tremendous expertise is employed in thinking and manoeuvring around the personalities that shape the outcomes that beset the country. Such expertise is the bread and butter of the political and business circles, which is equally well reflected in the media and realistically respected in the NGO and international circuit.

What is disconcerting however is the almost oblivious attention paid to matters of structure and functionality. Yet Sri Lanka is rife with structural and functional anomalies, which is positioned to terminally gnaw at advantages gained by changes in governments, peace talks, poverty reduction, etc. Using the example of the Public Administration System and the democratically elected Presidential and Parliamentary process explained is the structural and functional impediments that are crying out for serious remedy.

There is a vital homeostatic balance that is exercised between the parliament and the Public Administration System as a result of the former being elected and the latter employed on tenure. This translates to the Public Administration System being able to afford to think long term (since their tenure is secure) whilst being tempered by parliament's shorter range thinking occasioned by the politician's need to show results to entice its next bout of votes. In essence, this twofold structure serves to foster the seeking of a homeostatic balance between the long-and short-term needs of the country.

In Sri Lanka by constitutional and other legislative enactments various homeostatic relationships between races, languages, time spans etc. have been (un)wittingly flouted. These aspects are diagnosed using the cybernetic concepts of homeostasis and ultrastability.     

分析电磁散射问题的MGFFT方法

采用多重网格法（ＭＧ）分析电大尺寸物体的电磁散射，这种ＭＧ方法与已有的几种多重矩量法有本质的不同，与其他多层方法相比，它是一种高效率的迭代方法。再利用积分方程的卷积特性引入ＦＦＴ方法快速计算迭代过程中矩阵与矢量的乘积，从而构成ＭＧＦＦＴ新算法，数值结果表明ＭＧＦＦＴ方法具有很高的计算效率，适用于电大尺寸问题的分析。
