This work investigates epoxy composites reinforced by randomly oriented, short glass fibres and silica microparticles. A full-factorial experiment evaluates the effects of glass fibre mass fraction (15 wt% and 20 wt%) and length (5 mm and 10 mm), and the mass fraction of silica microparticles (5 wt% and 10 wt%) on the apparent density and porosity, as well as the compressive and tensile strength and modulus of the hybrid composites. Hybrid epoxy composites present significantly higher tensile strength (9%) and modulus (57%), as well as compressive strength (up to 15%) relative to pure epoxy.
Based on the population change data of 2005–2009, 2010–2014, 2015–2019 and 2005–2019, the shrinking cities in Northeast China are determined to analyze their spatial distribution pattern. And the influencing factors and effects of shrinking cities in Northeast China are explored by using multiple linear regression method and random forest regression method. The results show that: 1) In space, the shrinking cities in Northeast China are mainly distributed in the “land edge” areas represented by Changbai Mountain, Sanjiang Plain, Xiaoxing’an Mountain and Daxing’an Mountain. In terms of time, the contraction center shows an obvious trend of moving northward, while the opposite expansion center shows a trend of moving southward, and the shrinking cities gather further; 2) in the study of influencing factors, the results of multiple linear regression and random forest regression show that socio-economic factors play a major role in the formation of shrinking cities; 3) the precision of random forest regression is higher than that of multiple linear regression. The results show that per capita GDP has the greatest impact on the contraction intensity, followed by the unemployment rate, science and education expenses and the average wage of on-the-job workers. Among the four influencing factors, only the unemployment rate promotes the contraction, and the other three influencing factors inhibit the formation of shrinking cities to various degrees.
The project finance scenario has changed significantly around the world after the 2008 financial crisis and following the subsequent Basel III recommendations. Project finance loans from commercial banks and financial institutions have largely dried up, leaving it mostly to the export credit agencies and the bilateral and multilateral development banks to provide the institutional credit. Unfortunately, those sources are not enough, given the huge needs for construction of new infrastructure and renovation of the old ones across Asia, Africa and Latin America. The need for capital markets, through market listed financial products across asset class, unlocking a large part of domestic and corporate savings, has never been felt as strongly before. This article seeks to analyze the development story of various Asian capital markets and examine financial products, which have succeeded in their short history in receiving investor interest. The article also delves into the challenges to market development, policy imperatives and the issues relating to market liquidity and credit rating, which are the most significant influencers for public market float and investor interest.
Communication is an important part of organizational management activities and management behavior. In human resource management, effective communication plays an extremely important role. Human resources as one of the most critical resources of enterprises, the effectiveness of management is directly related to the survival and development of enterprises. Communication is the process of communication and transmission of information, effective communication is an important magic weapon for each enterprise to gain competitive advantage and success. This paper summarizes the important position and function of communication in enterprise human resource management, and puts forward the basic viewpoints and suggestions on how to establish the management communication mode from the perspective of human resource management.
With the development of economic globalization and integration, enterprises should survive and develop in the fierce market competition environment, need to enhance their own competitive ability, and human resources is the fundamental and key of enterprise competitiveness. In order to achieve the objectives of enterprise organization, we need to establish a sound performance appraisal system for employees and departments, and with effective incentive mechanism to fully mobilize the enthusiasm of the staff and create potential to continuously improve the performance level. The traditional staff performance appraisal method cannot meet the needs of modern enterprises, the establishment of a basic sound, with enterprise characteristics, to a full range of staff performance appraisal method as the core of the performance management system, from different levels of personnel to collect evaluation information, multi-angle, the whole perspective of the staff to conduct a comprehensive performance appraisal, comprehensively enhance the level of human resources management. This paper mainly elaborates how the enterprises implement the performance appraisal, the performance to achieve the effect and properly handle the enterprise and the staff assessment and assessment of the relationship between the performance appraisal for the enterprise staff put forward some ideas and suggestions.
Sustainable leadership matters, spreads and lasts. It is shared responsibility, that does not unduly deplete human or financial resources, and that cares for avoids exerting negative damage on the surrounding educational and community environment. In fact, sustainability does not simply mean whether something can last. It addresses how particular initiatives can be developed without compromising the development of others in the surrounding environment, now and in the future. Sustainable leadership is one of the most valued characteristics that employers and stakeholders are looking for, especially in this new fast changing market. Having a good Leadership sense is essential for the success of a company and for its collaborative working environment. Leadership is usually linked with sustained learning, success, diversity, capacity and maintaining a continuous development of other team members and coworkers. However, various authors are debating and discussing how we define good and sustainable leadership and what we expect from a leader to do, but few of them are raising the question how we can build and create leaders?. We present in this paper an overview of leadership definition and the challenges set by this important and complex concept. We propose a vision based on four pillars to create an adequate environment to build leaders. We present and describe our perspective on what we need to provide and establish as a company or a community in order to create an effective team of leaders in the perspective of the new requirements of the market and the expectations of companies.
