Ethics and the Financial and Budgetary Discipline in the Ministry of Defence

This article deals with the relation between ethics and financial and budgetary discipline during economic and social recession in the Czech Republic. We find causes of economic and social recession in the Czech Republic in the loss of democratic and human values. Czech Republic was ranked the 57th place in the Corruption Perceptions index 2013 out of the 177 countries assessed, which is the same result achieved by Bahrain, Croatia, and Namibia. Among the 31 European Union （EU） member states and Norway, Switzerland, and Iceland, the Czech Republic is on the 25th site. Market as well as public sector and public finances should follow unwritten rules of ethics and ethical behavior. Such rules should be followed especially by politicians, officials, soldiers, and businessmen. Do we need ethics in present time？ How is the role of the code of ethics in increasing financial and budgetary discipline in the defence sector？ Is it possible to measure efficiency of the code of ethics for financial and budgetary discipline？ We explain the importance of codes of ethics and formulate essential elements that each code of ethics must contain. Next, we deal with the main rules of both financial and budgetary disciplines. Furthermore, this article offers a comparison of several codes of ethics and describes the main problems in our implementation. In the end, we introduce our draft of Code of Ethics for Economic Service Officer in the Ministry of Defence and talk about possible influences of these codes on the quality of employee＇s performance.     

Automation,skill requirements and labour‐use strategies: high‐wage and low‐wage approaches to high‐tech manufacturing in the automotive industry

In light of debates about advanced manufacturing and concepts like Industrie 4.0, this article compares labour‐use strategies in highly automated automotive supplier plants in a high‐wage country (Germany) and a low‐wage region (Central Eastern Europe). It shows considerable differences regarding skill requirements on the shop floor and the use of precarious employment contracts and examines three potential factors that explain them: national institutional frameworks, the power of employee representatives and the role of the plant within the companies and value chains. The analysis shows that the labour‐use strategies depend less on process technologies per se, but rather on the institutional framework and the role of the factory in the rollout and ramp‐up of new products and new process technologies. Such a role requires close cooperation between employees in the manufacturing areas and in product development, which in turn requires particularly high skills. The role of employee representatives in influencing labour‐use strategies proves less important. The article uses quantitative data from a survey of employee representatives, as well as qualitative data from in‐depth company case studies.     

Why the Industrial Revolution Started in 18th Century Britain,Not China,from the Perspective of Globalization

The research examines the role of market expansion and international labor division in the British Industrial Revolution from the perspective of globalization. The research shows that British cotton textile output in pieces grew 275 times from the 1770s to the mid-1850s and documents that such growth would never have happened without a vast overseas market for the supply of raw cotton and the sale of products. The paper argues that the continuous and dramatic expansion of overseas markets allowed the British cotton industry to expand greatly without hitting the ceiling of marginal returns, leading not only to the great expansion of production, but also to technological and institutional innovations, and that international labor division made it possible for the industry to import ample amounts of raw cotton and export large amounts of cotton textiles. In contrast, foreign demand for Chinese cotton textiles increased significantly in the late 18th and early 19th centuries, but accounted for only 0.3% of production capacity, which was too little to lift the law of diminishing marginal returns and to induce either technological or institutional changes. As a result, only Smithian growths could be achieved through optimal resource utilization and specialization in production.

一种咬尾双二进制Turbo码并行译码方案

针对双二进制Turbo译码使用并行、滑动窗联合译码技术时，其咬尾的编码构造和窗分割导致边界状态值难以获取的问题，提出了一种新咬尾Turbo码并行、滑动窗译码方案——扩展交叠方案。该方案采用了边界状态盲估计和滑动窗状态回溯两种新译码技术。相比于传统的边界状态度量传播方法（又称迭代法），新方法一方面提高了边界状态度量的准确性，从而加快了译码收敛速度，一定程度上减小了高信噪比下的性能损失；另一方面避免了存储前一次译码的迭代度量值，更有利于硬件设计。仿真表明，新方案在64左右的中等窗长下即可消除并行和滑动窗影响，逼近原始无并行无滑动窗译码的性能，且窗长越小，其相较传统迭代法带来的译码性能增益就越明显。该方案具有较好的实用性和应用价值，可以满足5G的高速率、低时延和低存储的数据传输要求。     

Impacts of Road Access on Subjective Well‐being in Timor‐Leste

The impacts of access to roads on subjective well‐being at the household level are empirically examined using Timor‐Leste's nationally representative surveys. This paper examines not only the quantity, but also the quality of road infrastructure and, thus, extends existing studies that only consider the benefits of road accessibility. It is found that proximity to main roads may not necessarily result in improved welfare. Instead, ensuring all‐weather access to roads appears to be a more significant factor in raising household well‐being. Specifically, road accessibility during the rainy season reduces the probability of households reporting a ‘less than adequate’ (low satisfaction) response by 13–25 percent. This suggests that in Timor‐Leste, and likely in other developing economies under similar conditions, maintenance of existing roads is more essential to well‐being than building more roads.     

Physical activity advocacy in the UK: a multiple streams analysis of a hybrid policy issue

Physical activity is increasingly being defined as a major, complex, multi-sector issue. In order to understand more about how this expanded conception of physical activity is being factored into public policy, this article applies the multiple streams theory of policy change to examine the United Kingdom (UK) physical activity domain. Participant observation, policy analysis and media analysis are combined to examine the ways in which the political context, problem framing and policy solutions were brought together by a range of policy entrepreneurs. The study pays particular attention to how one lobby effort in the UK, the All Party Committee on Physical Activity (APCPA) attempted to elevate physical activity to a higher level of importance. The findings show how a hybrid form of organisation made up of traditional interest groups, corporations and government insiders, has successfully decreased ambiguity about physical activity and increased both official and public attention about the issue. The article suggests that while the multifarious benefits of physical activity and the diverse range of organisations involved have contributed to momentum towards policy change, these factors may also inhibit physical activity from remaining high on the policy agenda. Suggestions are offered for policy practices at a national level.
