Hausbetreuungskosten – Verrechnung als Betriebskosten

Dem Mieter dürfen als Betriebskosten im Sinne des § 21 MRG immer nur die angemessenen Kosten verrechnet werden, gleichgültig auf welche Art die Hausbetreuungskosten erbracht werden. Die Angemessenheit des Entgelts oder Werklohns stellt daher die Obergrenze dar. Die nach früherem Recht für Hausbesorger zu leistenden Betr?ge bilden keine H?chstgrenze für die Angemessenheit.

后阿拉法特时代的以巴关系--对中东和平进程三大关键因素的分析

阿拉法特辞世后,阿巴斯当选巴民族权力机构主席,完成了巴勒斯坦民族解放事业领导人的代际更替,沙龙组成新的联合政府,布什完成连选连任,巴、以、美三方的变化为推动中东和平进程的实现带来了历史性机遇,以巴恢复和谈势在必行。但由于三方特别是以巴双方各自面临重重困难,因此,在形式上恢复和谈容易,就实质性问题达成协议难。     

网络安全中的防火墙

全球信息化是人类发展的大趋势。计算机网络已渗透到社会生活的各个领域。由于网络的特性与弊端 ,网络安全问题日益严重。防火墙是一个加强机构网络与因特网之间安全访问的控制系统。虽然防火墙在当今因特网上的存在是很有生命力的 ,但它不能替代墙内的安全措施 ,不是解决网络安全问题的万能药方。     

当前我国袭警案件频繁发生的原因

当前,我国袭警案件频繁发生的主要原因有:社会治安形势的严峻性和复杂性;我国法律对警察执法缺少必要的保障;基层执勤民警的安全意识、自我保护意识不强;公安民警的警械装备不良和对使用枪支的困惑;舆论导向的负面作用;公安机关内部重义务轻权利的片面性教育。     

IMMIGRATION POLICY,BORDER SECURITY,AND MIGRANT DEATHS: AN IMPACT EVALUATION OF LIFE‐SAVING EFFORTS UNDER THE BORDER SAFETY INITIATIVE*

Subsequent to U.S. Border Patrol (USBP) efforts to control illegal immigration throughout the 1990s, concern arose over an apparent increase in deaths of illegal migrants as they began to undertake more treacherous routes to enter the United States from Mexico. In response, the Border Safety Initiative (BSI) was created to increase safety along the southwest border. Using multiple data sources, including the USBP BSI Incident Tracking System, this study evaluated the impact of life‐saving efforts performed under the BSI program. Results indicate that there has been no overall reduction in the rate of migrant deaths since BSI has been in operation. However, an evaluation of BORSTAR search and rescue teams and the 2003 Lateral Repatriation Program (LRP), which returned apprehended migrants from Tucson sector to less hazardous places along the border, were found to be effective in preventing migrant deaths. Policy Implications: Critics of U.S. immigration policy claim that the only way reductions in migrant deaths along the U.S.‐Mexico border can be achieved is through liberalization of immigration policy and relaxing of border security. Yet, for more than a decade, U.S. policy makers have increased restrictions on immigration and have tightened security at the borders. Considering this, alternative means must be deployed in order to save migrant lives in the near term rather than waiting for a reversal of immigration policy. This study suggests that proactive life‐saving measures implemented through a harm‐reduction strategy can have some impact on saving migrant lives.     

Scale, technique and composition effects in the Mexican agricultural sector: the influence of NAFTA and the institutional environment

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.

高校实践教学法律问题探析

高校的实践教学面临着高校、实习单位与学生之间权利义务关系的确定,实习期间学生的权益保护、学生和实习单位的人身或财产损害纠纷的解决等法律问题。从保护学生权益和平衡学生与实习（实训）单位利益关系的角度考虑,实践教学不仅应由教育法和民法调整,而且应将学生参加校外实习遇到的工伤问题、实习补贴、劳动安全、工作时间以及争议解决等突出问题纳入劳动法调整范围。此外,国家应完善高等教育立法和劳动立法,制定有关高校实践教学法律制度;高校应完善实践教学管理制度,建立高校实践教学风险防范机制。
