企业管理创新的动力、阻力及其应对要诀

管理要创新是企业发展的要求。企业管理创新会因内外部环境变化的多种力量所驱动,也会受到来自于个人和组织的诸多制约。为使管理创新顺利开展,应激发动力、减少阻力,做到五个要五个不要:要制造够大的危机感,不要满足现状;要有可信服的愿景,不要抽象口号;要充分沟通,不要闭门造车;要订立规划,不要急于冒进;要下放权力,不要害怕失控。     

Management across boundaries: A municipal dilemma

Public sector mergers have the potential of being viable alternative to other public sector reforms in the striving toward making public service provision more equipped to confront some of the challenges faced today. Mergers however often fail to deliver promised results. Previous research point to the importance of post‐merger integrating processes for realizing the synergies expected from mergers. However, so far these studies have focused on what occurs inside organizations and less on the interplay between different levels. By adopting a governance and top management perspective, this study increases our understanding of the importance of political decisions on the outcome of a merger in the public sector context. Further, this study increases our understanding of how organizational boundaries on different levels of merging organizations influence post‐merger integrating processes and the role of different actors as boundary spanners. The results of this study are based on five case studies of public sector mergers at the local level in Sweden.     

Implementing cloud-based medical systems in hospitals and strategic implications

Hospital information systems (HISs) accelerate hospital-related operations and reduce errors. However, previous HISs lack flexibility and scalability, consequently limiting the development of medical institutions. The characteristics of cloud computing services are crucial in helping hospitals overcome such a deepening dilemma. Nonetheless, only few medical institutions has begun partial utilisation of cloud computing services. Therefore, this research explores the resistance factors encountered during the organisation innovation process using the innovation resistance theory. Furthermore, the developmental barriers of an organisation are summarised into the following seven categories: the expertise barriers, operational barriers, resource barriers, rules barriers, market entry barriers, data security barriers, and barriers of cloud service quality. Utilisation of interpretive structural modelling also facilitates further exploration of the interaction structures among the barriers of organisational innovations. Based on the correlation and causation of the barriers, policy recommendations are proposed for the allocation of resources.     

Transgressing rights: La Via Campesina's call for food sovereignty / Exploring collaborations: Heterodox economics and an economic social rights framework / Workers in the informal sector: Special challenges for economic human rights

Abstract

The notion of rights is a powerful one, but the channels through which they have been promoted and enforced since World War II have militated against the more radical promise of rights. These explorations examine the question of economic rights with an international focus. The contributions touch on such diverse topics as the international peasant federation called La Vía Campesina, heterodox and social economic analyses, and the informal sector. The authors address the question of human rights with respect to the conditions that delimit and enforce these rights, the connections between macroeconomics and human rights, social movements that strive to protect these rights, and the different theoretical approaches to incorporating rights into an academic framework. Though each contribution's methodology and focus are different, the composite takes an important step in evaluating this very critical question of economic rights that greatly affects individual lives, social conditions, economic policies, and the study of economics.     

How Borrowing Constraints Hinder Migration: Theoretical Insights from a Random Utility Maximization Model*

We provide a theoretical framework to analyze how financial constraints hinder migration. Introducing wealth heterogeneity and borrowing constraints into a random utility maximization model of migration, we find evidence of multilateral resistance to migration stemming from borrowing constraints. We calibrate the model on 22 European countries, and we show that omitting the constraints biases upward the estimation of bilateral migration rates. We then simulate an increase in the bilateral cost of migration to the United Kingdom. We find that omitting the constraints biases downward the change entailed by the cost increase in the bilateral rates of migration to all destinations.     

董事长研发背景与企业数字化转型 ——来自中国上市企业年报文本大数据识别的经验证据

风景道不仅实现了道路从单一的交通功能向复合 功能的转变,也顺应了时代发展的迫切需求。风景道选线工 作作为风景道规划的前提与基础,既往研究一般只针对现有 路网进行分析评价,以此筛选出适宜改造升级为风景道的路 线,缺乏对于现有道路体系不完善地区的考虑。此外,现有 研究中的评价体系对于游客的视觉感受也缺乏合理的考量。 因此,针对现状道路体系不发达的区域,以景观视觉质量评 价的方法对游客视觉感受进行量化评估,将其与土地适宜性 相结合构建综合评价体系,利用最小累计阻力模型的原理, 辅助风景道选线规划。以新疆博尔塔拉蒙古自治州风景道规 划为例,以期为未来中国风景道的规划提供技术支持,助推 旅游经济的高质量发展。
