Real-Time Multi Fractal Trust Evaluation Model for Efficient Intrusion Detection in Cloud

Handling service access in a cloud environment has been identified as a critical challenge in the modern internet world due to the increased rate of intrusion attacks.To address such threats towards cloud services,numerous techniques exist that mitigate the service threats according to different metrics.The rule-based approaches are unsuitable for new threats,whereas trust-based systems estimate trust value based on behavior,flow,and other features.However,the methods suffer from mitigating intrusion attacks at a higher rate.This article presents a novel Multi Fractal Trust Evaluation Model(MFTEM)to overcome these deficiencies.The method involves analyzing service growth,network growth,and quality of service growth.The process estimates the user’s trust in various ways and the support of the user in achieving higher service performance by calculating Trusted Service Support(TSS).Also,the user’s trust in supporting network stream by computing Trusted Network Support(TNS).Similarly,the user’s trust in achieving higher throughput is analyzed by computing Trusted QoS Support(TQS).Using all these measures,the method adds the Trust User Score(TUS)value to decide on the clearance of user requests.The proposed MFTEM model improves intrusion detection accuracy with higher performance.

How the Health Care Nurse Supports and Enhances the Child’s Attachment to Their Parents

Objective: The aim of this study was to provide insight into how the Child Healthcare Clinic (BVC) nurse supports and encourages the child’s bonding to their parents during the regularly scheduled checkups at the healthcare clinics. Method: The study was done using a qualitative approach. The data was collected from the interviews of four focus groups which were comprised of a total of eighteen BVC nurses who work solely for the BVC. The resulting data was analyzed using qualitative content analysis. Results: The following theme emerged from the research material: Empower the parents in order to enable the child to have a healthy connection to the parents. This is accomplished by the BVC nurse building and creating a trusting relationship with the parents and providing support for them in their new roles as parents. The BVC nurses must have comprehensive knowledge about the needs and development of children and they need to have exceptional communication skills as well. It is also mandatory that the BVC nurse have access to cooperation and support from their colleagues and the support of other related professions. Conclusion: Providing support to parents during the bonding period of their infant children is a most important function for BVC nurses because there is much to be determined about children’s development and future possibilities during this formative period.

征迁改造居民的“知情意”——风险感知、政府信任及焦虑情绪对政策支持意愿的影响

以人为核心、关注民情、尊重民意是推进新型城镇化征迁改造的核心理念。已有研究主要关注居民的多元理性认知对征迁改造意愿的影响,对于情绪在认知与意愿的关系中发挥何种作用仍缺乏解释。运用质性研究方法,开发涵盖生计风险、适应风险和利益风险3个维度的征迁改造风险感知多维构念,以焦虑情绪为中介,建立征迁改造风险感知和政府信任对政策支持意愿影响的“知-情-意”模型。通过对18个新型城镇化改造试点地区居民的大规模实证调查发现:焦虑情绪在征迁改造风险感知对支持意愿的负向影响路径中发挥部分中介作用;政府信任通过直接方式以及减弱焦虑情绪的间接方式正向影响支持意愿,且直接效应显著大于间接效应。将焦虑情绪这一重要中介因素纳入居民意愿形成的分析框架,从及时评估并缓解居民焦虑情绪、面向不同群体实施差异化征迁改造政策、打通民意的“最先和最后一公里”以及提升基层政府公信力等方面为推动新型城镇化建设、避免群体性事件提供政策启示。

From the Voices in the Narratives of After-School Support Advisors: Support for Children’s After-School Support Advisors in Japan

This paper examines how advisors perceive the voices made by Mr.A(pseudonym),the founder of after-school support for children(Initiative Z:pseudonym)in Japan,to advisors who support children.Furthermore,the purpose of this study is to find out how advisors think about the voices and that the voices have led or not advisors to support children,if to do so,what points are key to continuing support for children.Therefore,in Initiative Z,I conducted a survey of two advisors who were approached by Mr.A,who is involved in supporting children as an advisor.As a result of analyzing the narratives obtained from interviews with the two advisors,it was found that the advisor had a sense of being recognized by Mr.A because Mr.A acknowledged the advisor’s way of life.This feeling on the part of the advisor led to trust in Mr.A,and the advisor was in tune with Mr.A’s thoughts on after-school support,suggesting that the advisor was providing support to the child.

Evaluation of preventive,supportive and awareness building measures among international students in China in response to COVID-19:a structural equation modeling approach

Background:Education institutions promptly implemented a set of steps to prevent the spread of COVID-19 among international Chinese students,such as restrictive physical exercise,mask wear,daily health reporting,etc.Success of such behavioral change campaigns largely depends on awareness building,satisfaction and trust on the authorities.The purpose of this current study is to assess the preventive,supportive and awareness-building steps taken during the COVID-19 pandemic for international students in China,that will be useful for planning such a behavioral change campaign in the potential pandemic situation in other parts of the world.Methods:We conducted an online-based e-questionnaire survey among 467 international students in China through WeChat.The data collection duration was from February 20,2020 to March 10,2020 and we focused on their level of awareness,satisfaction,and trust in authorities regarding pandemic measures.Simple bivariate statistics was used to describe the background characteristics of the respondents along with adoption of the partial least squares-structural equation modeling(PLS-SEM)as the final model to demonstrate the relationship between the variables.Results:In our study,the leading group of the respondents were within 31 to 35 years’age group(39.82%),male(61.88%),living single(58.24%)and doctoral level students(39.8%).The preventive and supportive measures taken by students and/or provided by the respective institution or authorities were positively related to students’satisfaction and had an acceptable strength(β=0.611,t=9.679,p<0.001).The trust gained in authorities also showed an acceptable strength(β=0.381,t=5.653,p<0.001)with a positive direction.Again,the personnel awareness building related to both students’satisfaction(β=0.295,t=2.719,p<0.001)and trust gain(β=0.131,t=1.986,p<0.05)in authorities had a positive and acceptable intensity.Therefore,our study clearly demonstrates the great impact of preventive and supportive measures in the development of students’satisfaction(R2=0.507 indicating moderate relationship).The satisfied students possessed a strong influence which eventually helped in building sufficient trust on their institutions(R2=0.797 indicating above substantial relationship).Conclusions:The worldwide student group is one of the most affected and vulnerable communities in this situation.So,there is a profound ground of research on how different states or authorities handle such situation.In this study,we have depicted the types and magnitude of care taken by Chinese government and educational institutions towards international students to relieve the panic of pandemic situation.Further research and such initiatives should be taken in to consideration for future emerging conditions.

员工跨界何以影响上司支持:上司信任与向上建议寻求的作用

在鼓励合作创新的背景下,员工跨界已然成为组织创新的源泉。尽管既有研究基于行为者视角检验了员工跨界对自身的影响,但其对上司影响如何鲜有研究关注。为此,本研究基于积极人际互动视角,采用情景实验(研究1)与多时点上下级匹配问卷调查(研究2),探讨员工跨界何时以及如何影响上司支持。研究1(N=220)结果表明,员工向上建议寻求水平越高,上司会对跨界员工产生更高程度的认知信任和情感信任,从而给予员工更高水平的人际支持。研究2(N=406)再次表明员工向上建议寻求正向调节员工跨界对上司情感信任的直接作用及其通过情感信任对上司支持的间接作用,但不支持向上建议寻求对上司认知信任路径的调节作用。以上研究结果有助于全面揭示员工跨界对上司支持的影响效应,从而为组织管理员工跨界与维持和谐上下级关系提供理论依据和决策借鉴。
