土地整治项目土方工程量计算方法研究

土方量的计算是土地整治项目规划设计的重要内容之一,准确快速地计算土方量对开展规划设计、控制总投资及分配资金具有重要意义,直接关系到土地整治项目的科学性和投资预算的合理性。本文以新建县流湖乡新塘村屈家垄里土地开发项目为例,分别应用ArcGIS和南方CASS技术进行土方量的计算,并对这两种方法进行了分析比较。通过分析得出,虽然ArcGIS计算土方量的精度比CASS计算的结果高,但是对基础数据的要求也高,CASS软件尽管精度略低,但是运行简单、快速。     

Sanctions and Leniency to Individuals,and its Impact on Cartel Discoveries: Evidence from the Netherlands

Many competition authorities employ a leniency programme to fight cartels. We examine the impact of the introduction of sanctions and leniency for individuals responsible for the cartel, on the number of cartel discoveries. In our empirical study of the Dutch leniency programme, we find that this did not lead to more cartels being desisted as the number of cartel discoveries decreases over time. An analysis of characteristics of cartel members shows harsher enforcement after the revision, which indicates that the decrease in cartel discoveries is in line with higher cartel deterrence. Nevertheless, the number of cartel cases involving leniency actually decreases after the revision.     

New Insights into Ethical Leadership: A Qualitative Investigation of the Experiences of Executive Ethical Leaders

Ethical leadership has become a thriving research field. However, on reviewing previous research, we argue that several fundamental questions remain unclear and need further investigation. (1) Ethical leaders are defined as behaving ‘normatively appropriate[ly]’ (Brown et al., Organ Behav Hum Decis Process 97(2):117–134, 2005), but it remains unclear what this entails. What specific behaviours does an ethical leader show? (2) To date, ethical leadership has focused primarily on leader behaviour towards employees. Which stakeholders apart from employees are important to the ethical leader, and what kind of ethical behaviour does the ethical leader show towards them? (3) What are further antecedents and consequences of ethical leadership? We addressed these questions by qualitatively analysing interviews with 17, mostly Swiss, executive ethical leaders. The results indicate that executive ethical leaders care not only about employees but also about other stakeholders, such as customers, suppliers, owners of companies, the natural environment and society. Additionally, this study identified a broad range of executive ethical leaders’ behaviours towards these stakeholders, and, therefore, may function as a useful resource for future quantitative studies. Furthermore, we identified several antecedents of executive ethical leadership, for example ethical role models, business strategy and owner’s values, and consequences such as effects on other stakeholders than employees. Finally, our results shed more light on the processes of ethical guidance of employees. Managerial implications and avenues for further research are discussed.     

基于协整和灰色关联分析的广西物流发展影响因素研究

利用协整检验对广西现代物流业发展与工业总产值、农业总产值、全社会固定资产投资总额、社会消费品零售总额、进出口总值五个影响因素进行分析,结果表明,广西现代物流业的发展与这五个因素存在长期稳定的均衡关系.并进一步利用灰色关联理论测算了广西现代物流与这五个因素的灰色关联度,发现广西现代物流业的发展与社会消费品零售的关联度最高,与全社会固定资产投资的关联度最低.     

高速铁路车站作业计划优化编制方法研究

以高速铁路车站作业总时间最短、设备均衡使用、提高车站作业效率为目标,考虑设备独占性、设备相容性、作业时间范围、作业接续性等相关约束条件,建立了高速铁路车站作业计划编制的0-1整数规划模型。并采用列生成算法来进行求解,以北京南站为例进行实证研究,得出北京南站车站作业计划并对计算结果进行分析,证明了模型和算法的合理性和有效性。     

Off-sites that work

Of all the meetings top executives go to in a year, none is more important than the strategy off-site, where the most essential conversations for the future of the business occur. Yet it is the rare management team that can say its strategy off-site truly changed the way the business is run. At best, participants do some vague direction setting and work on team-building skills; at worst, they write off the retreat as a waste of time and resources. It needn't be like that. From their two decades of experience designing and facilitating strategy off-sites in companies large and small around the world, the authors have distilled a set of best practices that businesses can use to make the most of this annual opportunity. Essentially, the problem with most strategy off-sites is that they're insufficiently structured. People think that if you schedule a meeting, invite top leaders (and perhaps an outside expert), and block off units of time to discuss big subjects, the rest will take care of itself. In reality, formlessness leads to aimlessness. Oddly enough, only rigorously designed meetings give rise to truly candid strategy discussions. That rigor starts before the meeting, when the scope of the matters discussed must be limited, the participant list drawn up accordingly, the relevant materials (and only those) sent out and absorbed, and a detailed agenda established. During the meeting, the pace and quality of the conversation can be managed through attention to politics and by using carefully tailored frameworks, decision points, and group exercises. After the meeting, an action plan ensures clear accountability and follow-through. If you and your executive team spend four days a year rafting down rivers together, you'll eventually get good at rafting down rivers. Spend four days a year having well -designed strategy conversations together, and you will transform your annual off-site from a meaningless junket into a genuine turning point for your business.     

施工现场库存管理系统动力学仿真分析——以上海世博会某场馆为例

不同于制造业库存管理,建设项目的物料库存受施工现场的限制,既要求不能一次订购超出现场库存能力的数量,又要求建材供应不能出现间歇.为满足施工现场库存管理这一要求,文章采用系统动力学仿真的方法,从施工承包商的视角,以钢材为例,构建了施工现场钢材库存模型.通过模型对不同采购预警值进行了对比分析,得出了合理的预警值.并对支付延迟可能产生的影响,给出了相应的应对策略,保证了施工的正常进行.最后,将模型在中国2010年上海世博会某场馆工程建设中进行了检验.     

商业孵化中的资源/能力聚合与竞争优势形成机制:来自硅谷Y Combinator案例的启示

Household Liquidity Constraints and Labor Market Outcomes: Evidence from a Danish Mortgage Reform

We study the causal effect of liquidity constraints on individual labor market outcomes by exploiting the 1992 mortgage reform in Denmark, which for the first time allowed homeowners to borrow against housing equity for nonhousing purposes. Following the reform, liquidity-constrained homeowners increased debt levels and had higher earnings growth and lower employment rates. The option to borrow against housing equity enabled liquidity-constrained individuals to move to high-wage jobs and invest in valuable human and physical capital. The results imply that relaxing household liquidity constraints during recessions can create better job matches, potentially increasing earnings and output in the longer run.
