Cloud data encryption and authentication based on enhanced Merkle hash tree method
Many organizations apply cloud computing to store and effectively
process data for various applications. The user uploads the data in the cloud has
less security due to the unreliable verification process of data integrity. In this
research, an enhanced Merkle hash tree method of effective authentication model
is proposed in the multi-owner cloud to increase the security of the cloud data.
Merkle Hash tree applies the leaf nodes with a hash tag and the non-leaf node
contains the table of hash information of child to encrypt the large data. Merkle Hash tree provides the efficient mapping of data and easily identifies the changes made in the data due to proper structure. The developed model supports privacy-preserving public auditing to provide a secure cloud storage system. The data owners upload the data in the cloud and edit the data using the private key. An enhanced Merkle hash tree method stores the data in the cloud server and splits it into batches. The data files requested by the data owner are audit by a third-party
auditor and the multi-owner authentication method is applied during the
modification process to authenticate the user. The result shows that the proposed
method reduces the encryption and decryption time for cloud data storage by 2-
167ms when compared to the existing Advanced Encryption Standard and

Graduate employability in Ghana: embedding social enterprise skills within the higher education framework. [version 1; peer review: 2 approved with reservations]
Levels of unemployment and environmental challenges make social entrepreneurship and social enterprise very important for the sustainability of society. Higher education has played a fundamental role in driving entrepreneurship and innovation in local, national, regional, and global contexts. The authors of this article explore the state of the legislative framework in Ghana, as well as social enterprise education, stakeholder engagement, models and challenges. The methodology applied for this paper is concept mapping, enabling the critical exploration of the relevance of social enterprise in the context of higher education, and demonstrating how it could practically serve as a panacea to rising youth unemployment. This research concludes by making a case for including social enterprise in the higher education curriculum
Re-assessing entrepreneurship education and gamification as a learning process
The role of entrepreneurship in moving forward economic sustainability, boosting national and international markets by improving employability is undeniable. Although personal characteristics play an important role in the success of entrepreneurs, several studies have shown that entrepreneurship can be learned and trained. This makes the entrepreneurship education all the more important and worth unravelling. There is a correlation between entrepreneurship education and success of the entrepreneurs, and different pedagogical approaches are often introduced into teaching making entrepreneurship a worthwhile discipline in higher education. In this chapter we re-asses entrepreneurship education by concentrating on gamification method through the exploration of current studies on game-based learning. The findings from the literature suggest different views on entrepreneurship education and its importance. However, they help in the development of a road map to educate entrepreneurs and stimulate them to become more successful via creating an entrepreneurship culture. Different pedagogical approaches are noted, and these upsurge the value of entrepreneurship education, by increasing students’ motivation, attitude, and engagement. Much attention is drawn to gamification as a learning process, and the analysis of different viewpoints has provided a deeper understanding, strong platform, and appreciation of game-based learning approaches in higher education
The therapeutic goals set by university students in an anonymous web-based therapy and support setting
The interest in student mental health and wellbeing has increased in recent years. Additionally, there is a rising volume of students seeking support. Numerous online resources have been developed to meet this need, including anonymous web-based therapy. To date, there has been little focus upon how students may utilise such a service, and this study examines routine evaluation data (solicited from a Goal-based Outcome Measure) from a United Kingdom based service provider. Over the course of one academic year (2018–2019), 211 students articulated therapeutic goals within Kooth Student, a web-based therapy and support service for individuals in higher education. These goals were examined for key trends. The students identified a total of 625 goals to work on in therapy, with individuals setting an average of three goals each. The most common goals focused upon obtaining additional support within the service and exploring their emotions. The results suggested that female students were more likely to move towards achieving their goals, with goals that did move shifting an average of 7.74 on a 10-point scale. Practical goals that focused upon getting more help, both inside and outside the service, were most likely to be achieved. In contrast, self-help/self-care goals were less likely to be achieved. These results provide a helpful insight into how students made use of therapy and highlight the importance of the interaction that web-based services have with other provision (web-based and in-person). They also demonstrate the challenge of capturing meaningful outcome data in anonymous services
Getting a PhD by professional practice: autoethnographic accounts by two mental health nurses and their supervisor
Changes in PhD regulations at several universities mean that there are a number of
routes available to study for a PhD, other than the traditional PhD by research. Many
offer a PhD by publication, which can either be via a retrospective route or a prospective
route. Others offer a PhD by public works or professional practice, which are both
retrospective. Both options may be available to mental health nurses, who may have
contributed greatly to the development of the profession, but never had the time or
encouragement to pursue PhD studies before. This paper features two autoethnographic
accounts by two highly experienced mental health nurses, who achieved their PhDs in
the last year. They reflect on their own backgrounds in mental health nursing and what
persuaded them to study for a PhD. If you thought your own academic journey was
finished, maybe you may need to think again
Young people’s experiences of death anxiety and responses to the Covid-19 pandemic
Capacity for death awareness and death anxiety in young people has been previously documented but the impact of Covid-19 is not currently known. Therefore, the aim of this study of this study was to explore young people’s experiences and responses to the Covid-19 pandemic. Qualitative data was collected from young people via a two-stage process across the United Kingdom: Stage One consisted of an online questionnaire; Stage Two comprised online semi-structured interviews. Responses for Stage One of the study totalled 120 young people; 9 of these were interviewed for Stage Two of the study. Thematic analysis of data identified four themes relating to young people’s experiences of the Covid-19 pandemic: death anxiety; mental health; normalising death; and identified support needs. Young people experienced heightened death anxiety due to the pandemic but death also became normalized for them and their mental health was negatively affected
Children's experiences of death anxiety and responses to the Covid-19 pandemic
The aim of this study was to explore children's experience and responses to the Covid-19 pandemic through their illustrations and short narrations. During October 2020 and January 2021 data was collected from thirteen children aged 9–10 years old in a primary school in the North-West of England. Children were asked to draw their thoughts and feelings about the pandemic and to write a short narration to accompany the drawing. Thematic analysis of data revealed that during the pandemic children at this age have an understanding of death, experience death anxiety and are able to use creative expression to facilitate meaning of the impact of lockdown on their lives such as feeling isolated, lonely, sad and bored. Creative expression also facilitated adaptive coping mechanisms derived from being able to spend more time with family. The data on primary school children is part of a larger study which involved surveys and interviews with children aged 12–16 years in secondary schools
Graduating in uncertain times: The impact of COVID ‐19 on recent graduate career prospects, trajectories and outcomes
This article examines the impacts of the COVID‐19 pandemic on recent UK graduates' initial employment outcomes and how they experience the transition into a challenging labour market context. We draw on longitudinal survey and interview data, collected from recent graduates who had mainly graduated during the onset of the COVID‐19 pandemic in summer 2020 that examines graduate perception of the labour market, impacts on labour market entry impacts and early career progression and effects of periods of unemployment or under‐employment. The article shows some of the main impacts of the recent pandemic‐affected labour market, including: widespread concerns about job opportunities and employer support, the perceived employment impacts of the pandemic and early signs of scarring and labour market disorientation amongst those who were struggling to find employment of their choice. Such experiences are clearly intensified during the specific COVID‐19 context, but the policy implications they raise have wider relevance for supporting graduates during future periods of labour market volatility
Design of a 3.8-GHz Microstrip Patch Antenna for Sub-6 GHz 5G Applications
This paper presents a design of a centre-fed Rectangular Microstrip Patch Antenna (RMSA) that resonates at exactly 3.8 GHz. The effect of the dielectric material’s choice, substrate height, dielectric constant, and the substrate material is on the RMSA for a constant resonant frequency while maintaining signal integrity and reducing signal loss. The antenna’s gain and input return loss are improved by adjusting the upper and lower bounds of the height of the dielectric substrate. Results show that a maximum bandwidth of 350 MHz, a gain of 7.77 dBi, and input return loss (S11) of below–33 dB were obtained. Furthermore, a smaller dielectric constant below 2.5 and a Voltage Standing Wave Ratio (VSWR) below 2 dB will conveniently provide a wider bandwidth (BW) of over 250 MHz which is convenient to meet frequency range 1 (FR1) bandwidth expectation
DocCompare: an approach to prevent the problem of character injection in document similarity algorithm
There is a constant rise in the amount of data being copied or plagiarized because of the 1
abundance of content and information freely available across the internet. Even though the systems 2
try to check documents for the plagiarism, there have been trials to overcome these system checks. 3
In this paper, a concept of character injection used to trick the plagiarism is presented. It is also 4
showcased that how the the similarity check algorithms based on k-grams fails to detect the character 5
injection. In order to eradicate the problem or error in similarity rates caused due to the problem of 6
character injection, image processing based approach of multiple histogram projections are used. An 7
application is developed to detect the character injection in the document and produce the accurate 8
similarity rate. The results are shown with some test documents and the proposed method eliminates 9
any kind of character injected in the document that tricks the plagiarism. The proposed method has 10
addressed the problem of character injection with image processing based changes in the existing 11
methods of document-similarity check algorithms based on k-grams
