<p>Based on a survey of 322 parents of migrant children aged 3 to 10 in Hangzhou, Ningbo and Jiaxing, Zhejiang Province, China, the study found that nearly 70% of parents have been working in Zhejiang for 5-10 years, and 28% of them have worked for more than 10 years; 94% of them hold agricultural household registration and 6% of them hold non-agricultural household registration. Nearly 70% of these families have 2 to 3 children and 16% of them have 4 children. Those children who can get into the local public kindergartens and primary schools are all study in the local institutions and most school-aged children and the majority of pre-school children who do not meet the admission requirements for local public kindergartens and primary schools return to their hometown due to the pressure of tuition fees. At the same time, family education is not efficient, more than half of the children’s spare time is occupied by television and video games, the proportion of reading and sports activities is only a little more than 10%. Most parents have little time to read, do homework and physical exercise with their children, because of their heavy work or low level of education. This paper puts forward some relevant countermeasures and suggestions, hoping to change this situation.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0629/a.php" alt="Hit counter" /></p>

Authors: Lhokseumawe Syukran 
Published: September 2020

To embody the spirit of liberalism, Rogers has been lowered into a more practical method of learning, while Islam does not have the concept of ( practical method) education that truly reflects liberal education. However, the differences and advantages of one another, not hinder to combine these two concepts . Because if the two concepts are combined, then education will produce high-quality output : master common knowledge (non - religious) and religious knowledge, capable of autonomous thinking, creative, wise and able to resolve any problems faced .
Merging these two concepts should not be exhaustive, but merely complementary. Islamic education is already mempuyai spirit of liberalism, the philosophy and objectives clear, no need to adopt the goals and spirit of liberalism offered Rogers. In contrast, the Islamic education system must adopt a way of teaching (practical method) of educational liberalism Rogers.

Published: September 2020

The study aims to determine the organizational communication process between lecturers and staff in shaping the organizational climate as an effort to increase student satisfaction at the Ar-Raniry State Islamic University in Banda Aceh. In conducting this research, researchers used a qualitative approach using interview techniques with several members of the organization namely lecturers, employees, and students. Researchers also made direct observations at five faculties at UIN Ar-Raniry. From the results of the research conducted showed that the organizational communication process that has been going on between lecturers, staff, and students is still not running effectively. This is due to miscommunication that occurs as well as unsatisfactory employee service performance. The tight schedule of several lecturers is also a problem in increasing student satisfaction. Organizational communication that occurs linearly, top down, even circularly has not yet been formed as a whole and effectively. This then forms a closed organizational climate. The closed climate of organizational communication has been a limiting factor for the communication of lecturers and staff in increasing the satisfaction of UIN Ar-Raniry students.

Published: September 2020

Purpose: This study aims to evaluate the performance of selected private sector Banks in India. The aim is also to study the profitability performance of these selected banks.
Approach/Methodology/Design: Eight private Banks were selected as a sample for the study. The statistical tools employed in the study include Minimum and Maximum Net Profit Ratio, Descriptive Statistics and One-Way ANOVA test for the evaluation of performance of Banks. The period for the study is from 2011-12 to 2018-19, and this study is totally based on secondary data.
Findings: The results of the study reveal that there is a significant difference of Net Profit of the selected banks. The financial performance of HDFC Bank is continuously in a good condition due to the high profit earned and the proper management that is employed. The results indicate that Yes Bank is in a deteriorating financial position because of governance issues, false assurance to customers, non-serious investors, non market-led revival in sight, outflow of liquidity, and non-disclosure practices. Axis Bank and ICICI Bank are slowly declining within the market. Jammu and Kashmir Bank suffered losses in the year 2016-17 due to the tune of Rs 16,000 crores during the five months long unrest in the Kashmir valley.
Practical Implications: In today’s scenario, most of the banks have more Non-Performing Assets. Due to this condition, many banks go to liquation and merger/acquisition. This paper attempts to examine the current conditions of selected private sector banks in India, assisting in presenting statistical analysis that will be of use to investors as well as management teams of the banks.
Originality/value: Nowadays, Banking sector is one of the fastest growing sectors and huge funds are invested in banks. The banking system is becoming more complex and therefore there is a strong need to evaluate the performance of the banks. The originality in this study lies in the attempt to provide up-to-date assessment of eight top banks in India.
