Capitalized investments with entry and exit options and paradoxical tax effects

Investment decisions are often characterized by uncertainty, irreversibility, and timing flexibility. We use a binomial model to investigate the interdependencies of effects from profit taxation and both an option to delay and an option to abandon on investment decisions. We show that increasing the tax rate can lead to paradoxical tax effects, i.e. it may foster an investor’s willingness to invest. By contrast, if we abstract from the abandonment option, such paradoxical effects cannot be identified. Hence, we show that paradoxical tax effects can be caused by an abandonment option. Our results are helpful for investors facing risky investment opportunities and for improving typical valuation approaches.     

Informational Interview: Broadening Helping Field Professional Students’ Perception of Employment Opportunities in the Real World

Abstract

This study examines the impact of an informational interview assignment on students’ understanding of the human services field and their educational and career plans. Twenty-three students completed both questionnaires and open-ended questions in this study. Questionnaires were collected before and after the assignment to assess student’s knowledge, beliefs, attitudes of their major as well as a measurement of their confidence in their ability to succeed in the major; open-ended questions for student reflection were also collected after the assignment. Findings from the survey and open-ended questions suggest (a) the assignment was helpful for students to gain an understanding of the field, (b) students had an increase in a positive attitude toward the field, (c) the need to help students further clarify educational and career goals. Future research should encourage longitudinal studies of the effect of the informational interview on student’s educational and career plans.     

运输成本对产业集聚的影响：理论分析与实证检验

影响集聚经济的因素主要可归为运输成本和生产密度这两大类。考虑到生产密度本身又与运输成本间的关系十分密切,因而在影响集聚经济的所有因素中,运输成本的重要性始终都是不可忽视的。随着社会经济的进一步发展以及科学技术的不断进步,尽管相关的新技术在方便了远程管理及供应链管理的基础上也大大降低了运输成本在社会生产与生活中的重要地位,然而其却始终无法轻易地改变经济地理的内在规律;原因主要在于:无论如何,空间距离均有可能使知识、技术、产品、人员的交流与互动会变得更加的便利和有效。应该说国内外的实践经验已在相当程度上检验了这一点。     

论忽必烈政权"汉化"进程中的士人政策

忽必烈时期,在推行汉法,大兴文治的过程中,重视对士人政策的革新和完善。此主要表现在：征用儒雅,量才擢用;兴举学校,造育人才;尊孔崇儒,优渥士人三个方面。这些政策中虽存在民族歧视、科举废弛、“重吏轻儒”等不足,但仍显著提升了士人,尤其是汉族士人的社会政治地位,对于促进蒙元的汉化进程和巩固政权统治起到了重要作用。     

伤害胎儿行为刑事处理问题研究

目前我国的刑法体系无法包容伤害胎儿的行为,从狭义的伤害胎儿行为出发,对我国实践中伤害胎儿行为处理办法和理论争议进行总结和评析,以承认出生后为活体的“人”在胎儿时期的生命和健康是一项刑法法益为前提,提出了增设故意伤害胎儿罪的主张,并对故意伤害罪的构成要件和罪名安排进行了具体的设想。     

中俄林地物权比较研究

对森林资源物权的研究不仅可以推动森林资源的优化配置与利用,而且对社会的可持续发展及生态环境建设意义重大。本文首先阐述了林地物权的基本内涵,然后从所有权、他物权两个方面对中俄两国的林地物权进行了对比。在林地物权实际内容中,探讨了中俄林地种植权、采伐权、采集权、景观利用权、狩猎权、生态补偿权、林业扶持权7种权利的相关内容。此外,文章还从林地物权的灭失和移转两个方面对比了中俄在林地物权变动制度上的规定,最后对完善我国林地物权立法,推进集体林权改革提出了5项建议。     

中文语境下“新闻”概念嬗递考辨——一种思想史的视角

文章在与一个个意义显明的概念相对应的关系中,逐层揭示出“新闻”概念及其在中文语境中所具有的历史意义。将中文“新闻”概念置于与五个概念（习见,旧见,意见,异见,所见）的对比关系中,辨析随着历史的延革而逐渐建构而成的“新闻”概念的五个内涵,新闻概念的五个内涵最早出现于什么年代得到了考证。它们如何随着历史之轴逐渐呈现,逐层叠加在第一次出现的“新闻”二字之上,时隐时现,或弱或强,直至形成了现当代中文语境中的“新闻”概念。而不同内涵与时而成的显隐强弱,一定程度上反映出了中国历史的演变和政治、文化意识形态的迁易。     

Strategic interaction sequences: the institutionalization of participatory budgeting in New York City

ABSTRACT

An interactive approach to social movements highlights time dynamics in ways more correlational approaches do not, in that interaction and outcomes unfold in sequences as players react to one another. Some aspects of these engagements are shaped by institutional schedules, while others leave discretion to the players. Some institutional schedules, meanwhile, may be reshaped by strategic interactions. By examining the implicit trade-offs and explicit dilemmas that pervade strategic interaction, we see how some are tightly linked to time whereas others more closely reflect ongoing structural situations. Analyzing the case of participatory budgeting in New York City, we focus on two trade-offs, ‘being there’ and ‘powerful allies’, that appear when social movements attempt to institutionalize new policies and processes. These time-based strategic trade-offs complicate activists’ efforts to secure lasting gains.     

Interactive association between negative emotion regulation and savoring is linked to anxiety symptoms among college students

Abstract

Objective: This study tested the interactive relationships between college students’ perceived capability of regulating negative emotions and savoring positive emotions on mental health outcomes, including anxiety and depressive symptoms. Participants: Participants were healthy undergraduates (n?=?167) recruited from two universities in Hong Kong. Methods: Students completed four scales assessing their perceived capability of using strategies to regulate negative and positive emotions and their anxiety and depressive symptoms. Results: Findings revealed that both anxiety and depressive symptoms were negatively linked to perceived capabilities of regulating negative emotions and savoring positive emotions. Furthermore, regulating negative emotions interacted with savoring positive emotions to predict anxiety symptoms. Conclusions: The need to simultaneously perform negative and positive emotion regulation is highlighted. The results suggest the priority of regulating negative emotions over savoring positive emotions in alleviating anxiety symptoms. Nevertheless, enhancing positive emotion shows greater benefits for those who are less adept at regulating negative emotions.
