A Traffic Analysis on Serverless Computing Based on the Example of a File Upload Stream on AWS Lambda
Venue: Big Data Cogn. Comput.
Year: 2020

The shift towards microservisation which can be observed in recent developments of the cloud landscape for applications has led towards the emergence of the Function as a Service (FaaS) concept, also called Serverless. This term describes the event driven, reactive programming paradigm of functional components in container instances, which are scaled, deployed, executed and billed by the cloud provider on demand. However, increasing reports of issues of Serverless services have shown significant obscurity regarding its reliability. In particular, developers and especially system administrators struggle with latency compliance. In this paper, following a systematic literature review, the performance indicators influencing traffic and the effective delivery of the provider's underlying infrastructure are determined by carrying out empirical measurements based on the example of a File Upload Stream on Amazon's Web Service Cloud. This popular example was used as an experimental baseline in this study, based on different incoming request rates. Different parameters were used to monitor and evaluate changes through the function's logs. It has been found that the so called Cold Start, meaning the time to provide a new instance, can increase the Round Trip Time by 15% on average. Cold Start happens after an instance has not been called for around 15 min, or after around 2 h have passed, which marks the end of the instance's lifetime. The research shows how the numbers have changed in comparison to earlier related work, as Serverless is a fast growing field of development. Furthermore, emphasis is given towards future research to improve the technology, algorithms, and support for developers.
Childhood Maltreatment, Adult Attachment, and Depression as Predictors of Parental Self Efficacy in At Risk Mothers
Year: 2011

Childhood abuse and neglect can have far reaching effects on adult relationships, mental health, and parenting. This study examined relations between maltreatment types, anxious and avoidant adult attachment, maternal depression, and parental self efficacy in a community sample of 76 at risk mothers. After controlling for other forms of maltreatment, emotional abuse uniquely predicted higher levels of anxious attachment and maternal depression. Structural equation modeling revealed that childhood maltreatment predicted lower parental self efficacy through indirect pathways involving anxious attachment and depression. Specifically, maltreatment's influence on maternal depression was mediated by attachment anxiety, while its influence on parental self efficacy was mediated by depressive symptoms. Results are discussed in terms of attachment theory and ways in which parental self efficacy contributes to adaptive caregiving behavior.
Current status of dental English education in China
Year: 2016

The teaching of dental English for undergraduate students plays an important role in dental education. Most dental schools or colleges have set up the course of dental English education in China. However, this course lacks of a unified educational plans, contents and goals based on actual situation of dental students, which does not fully achieve the teaching purpose. This study was aimed to explore the developmental direction of the course of dental English education through comparison among different dental schools or colleges in China, in order to find out the teaching mode of dental English education, and promote the teaching effect and cultivation of international dental talents.
Students' self assessment of competencies in the phantom course of operative dentistry
Venue: European journal of dental education official journal of the Association for Dental Education in Europe
Year: 2019

The aim was to assess the competencies of undergraduate students in their roles of dental expert, scholar, communicator, collaborator, health advocate, manager and professional.  For this retrospective, pseudonymised observational study (pre /post testing) students in two cohorts in their first clinical semester in operative dentistry were asked to judge their competencies (1 very good to 6 insufficient) with a learning objective catalogue designed at the Goethe University Frankfurt (modelled after the National Competency Based Learning  Catalogue Dentistry) at the beginning and end of their phantom course. In order to relate the students' subjective competency judgements to objective evidence of their skills, at the end of the semester their marks from the summative Objective Structured Practical Examination (OSPE) were compared with the subjective judgement of their exam performance before the final results were known.  The reliability of the evaluation sheet was evaluated with Cronbach's alpha 0.98. The students judged their competencies as "sufficient" (4.23 0.51) at the beginning and "satisfactory" (2.82 0.43) at the end. A significant improvement in competencies was observed within all roles. The students' subjective judgement of the exam results (3.66 0.62) was significantly correlated with the actual marks (3.69 0.83) in the OSPE at 0.3547 (P 0.0015)  The evaluation instrument showed excellent reliability. The students judged that their competencies significantly increased during the semester. The triangulation with the actual marks in the context of an OSPE demonstrated a significant correlation with the students' exam judgements.
Vision based gesture recognition for human robot symbiosis
Venue: 2007 10th international conference on computer and information technology
Year: 2007

This paper presents a vision based gesture recognition system for human robot symbiosis. The system is based on the visual information of the face and is commenced with the recognition of face gesture by connected component analysis of the skin color segmentation of images in HSV color model and neural network based pattern matching strategies. On gesture recognition, robot is being instructed to perform certain tasks by issuing commands. The system is capable of recognizing static gestures comprised of the face poses, and dynamic gestures of face in motion. The effectiveness of the system has been justified over some experiments. The system has been demonstrated with an entertainment robot named ldquoAIBOrdquo as a human robot symbiotic relationship.
Learning from Human Feedback: Challenges for Real World Reinforcement Learning in NLP
Venue: ArXiv
Year: 2020

Large volumes of interaction logs can be collected from NLP systems that are deployed in the real world. How can this wealth of information be leveraged? Using such interaction logs in an offline reinforcement learning (RL) setting is a promising approach. However, due to the nature of NLP tasks and the constraints of production systems, a series of challenges arise. We present a concise overview of these challenges and discuss possible solutions.
Digital Voting: A Blockchain based E Voting System using Biohash and Smart Contract
Venue: 2020 Third International Conference on Smart Systems and Inventive Technology (ICSSIT)
Year: 2020

The voting method is the mechanism for implementing the people's view to better administer the system. Throughout recent years, conventional votes have pleased neither people nor government authorities. They are not entirely safe since ballots are simple to strike. It also challenges voter safety and transparency. Additionally, counting the votes takes too long. Modification of voting worldwide is an intriguing issue in current voting system. To solve these problems Digital technology is used in the voting phase for citizens in many nations. Digitalisation alone can not fix the issues fully. There are also many ways of manipulating or modifying digital technology and hindering voting. There should be fairness, independence and impartiality in the voting method. By analyzing the aforementioned problems, this research work combines the digitalisation with the blockchain technology to provide a voting mechanism. The main goals of our voting mechanism are to provide integrity, anonymity, privacy, and security of voters. With the use of markle tree and fingerprint hash, the data integrity and anonymity, privacy, security of the voters has been achieved in our proposed digital voting systems.

Social acceptance of renewable energy innovation: An introduction to the concept
Year: 2007

This paper introduces the special issue on Social Acceptance of Renewable Energy Innovation. It is a collection of best papers presented at an international research conference held in Tramelan (Switzerland) in February 2006. While there are ambitious government targets to increase the share of renewable energy in many countries, it is increasingly recognized that social acceptance may be a constraining factor in achieving this target. This is particularly apparent in the case of wind energy, which has become a subject of contested debates in several countries largely due to its visual impact on landscapes. This paper introduces three dimensions of social acceptance, namely socio political, community and market acceptance. Factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects. The third dimension, market acceptance, has received less attention so far and provides opportunities for further research, particularly from management scholars.
UNEVEN POLICY IMPLEMENTATION IN RURAL CHINA
Venue: The China Journal
Year: 2011

While research on "selective policy implementation" has provided explanations for why some policies are more likely to be implemented well than others, this contribution is concerned with the phenomenon of one and the same policy being implemented well in one locality, but not in another. From a vantage point of policy implementation instruments, it examines the uneven implementation of the rural tax reform that preceded the recent Construction of a Socialist New Countryside (jianshe shehuizuhyi xin nongcun) The study reveals that "competition under hierarchy" provided incentives for some localities to continuously improve the tax reform by means of local level experiments. Conversely, it prompted a great number of localities to circumvent or even sabotage the reform, thereby forcing the central government to make repeated financial concessions and eventually to centralize the provision of rural public services. By focussing more on processes than on end results, the article demonstrates how different experiences in local policy implementation can contribute to the overall development of a policy.
Cytotoxic prenylated flavonoids from the stem bark of Maackia amurensis.
Venue: Chemical pharmaceutical bulletin
Year: 2009

Five new prenylated flavonoids, maackiaflavanone A (1) maackiaflavanone B (2) maackiapentone (3) maackiapterocarpan A (4) maackiapterocarpan B (5) along with eleven known flavonoids were isolated from the stem bark of Maackia amurensis. The structures of the new compounds were elucidated by spectroscopic methods. The cytotoxicities of compounds 1 4, 6, 8 12 and 14 16 against four human cancer cell lines, A375S2, HeLa, MCF 7 and HepG2, were tested by the 3 (4,5 dimethylthiazol 2 yl) 2,5 diphenyltetrazolium bromide (MTT) method. Among the compounds tested, compound 2 showed the strongest cytotoxic activity with IC(50) value of 7.8 microM against A375S2 and euchrenone b(1) showed the most potent cytotoxicity with IC(50) value of 4.5 microM against HeLa.
4D modeling of soil surface during excavation using a solid state 2D profilometer mounted on the arm of an excavator
Year: 2020

The aim of this research is to create a 4D point cloud map from a trench through a solid state 2D profilometer. The profilometer is integrated with an 8.5 ton medium size excavator's machine control system with pose calculation. Accordingly, the point cloud was transformed to a work coordinate system. We used a recently developed pulsed time of flight laser light detection and ranging profilometer, which makes possible simultaneous depth measurements to 256 directions in an angle range of 20deg and measurement range from 1 m to 8 m with a frame rate of 25 frames per second under sunlight conditions (50 Klux) The analysis is based on a 4D map, which consists of 3D data (XYZ) and intensity information. The XYZ coordinates give the position of an object, and the intensity data can be used to roughly identify materials and recognise surface markings, such as texts. An analysis of the results shows that the detection accuracy of the profilometer is better than 10 mm. The main advantages of our method are accuracy, high update rate, compact size, real time measurement and a construction without moving parts. Our technique has a great potential in construction applications, where accurate measurements of a surface shape are needed.

Atypical Presentation of Human Acute Muscular Sarcocystosis: Sarcocystis Nesbitti Confirmed on Molecular Testing
Venue: The American journal of case reports
Year: 2019

Male, 51 Final Diagnosis: Acute muscular sarcocystosis Symptoms: Fever myalgia Medication:  Rare disease  Acute muscular sarcocystosis (AMS) is one of a spectrum of diseases caused by the Sarcocystis parasite which infects humans in regions where it is endemic. Infections present with non specific signs and symptoms and have been known to occur in clusters.  A 51 year old Vietnamese male presented to Tan Tock Seng Hospital, Singapore with 3 weeks of fever, urticarial rash, non productive cough, and lower back pain. He had an extensive travel history prior to presentation. Magnetic resonance imaging (MRI) showed myositis involving the paravertebral and upper thigh muscles. The infection was confirmed on open muscle biopsy and Sarcocystis nesbitti was identified on molecular testing. The patient was treated with prednisone and methotrexate.  AMS must be considered in a patient with history of exposure to an endemic area. Diagnosis of the condition and identification of S. nesbitti as the causative organism will help to further study of this particular condition and guide treatment.
Teaching medical professionalism: a qualitative exploration of persuasive communication as an educational strategy
Venue: BMC medical education
Year: 2020

Across the world, local standards provide doctors with a backbone of professional attitudes that must be embodied across their practice. However, educational approaches to develop attitudes are undermined by the lack of a theoretical framework. Our research explored the ways in which the General Medical Council's (GMC) programme of preventative educational workshops (the Duties of a Doctor programme) attempted to influence doctors' professional attitudes and examined how persuasive communication theory can advance understandings of professionalism education.  This qualitative study comprised 15 ethnographic observations of the GMC's programme of preventative educational workshops at seven locations across England, as well as qualitative interviews with 55 postgraduate doctors ranging in experience from junior trainees to senior consultants. The sample was purposefully chosen to include various geographic locations, different programme facilitators and doctors, who varied by seniority. Data collection occurred between March to December 2017. Thematic analysis was undertaken inductively, with meaning flowing from the data, and deductively, guided by persuasive communication theory.  The source (educator) the message (content) and the audience (participants) were revealed as key influences on the persuasiveness of the intervention. Educators established a high degree of credibility amongst doctors and worked to build rapport. Their message was persuasive, in that it drew on rational and emotional communicative techniques and made use of both statistical and narrative evidence. Importantly, the workshops were interactive, which allowed doctors to engage with the message and thus increased its persuasiveness.  This study extends the literature by providing a theoretically informed understanding of an educational intervention aimed at promoting professionalism, examining it through the lens of persuasive communication. Within the context of interactive programmes that allow doctors to discuss real life examples of professional dilemmas, educators can impact on doctors' professional attitudes by drawing on persuasive communication techniques to enhance their credibility to demonstrate expertise, by building rapport and by making use of rational and emotional appeals.
Parliamentary accountability in multilevel governance: what role for parliaments in post crisis EU economic governance?
Year: 2018

How has the new structure of European Union (EU) economic governance affected the ability of parliaments (national and European) to scrutinize and control economic policy? Departing from the premise that executive power needs to be matched by appropriate parliamentary control, this contribution argues that parliamentary powers have been compromised in EU economic governance. Although budgetary powers remain formally at the national level, governments' decisions have become constrained and national parliaments find themselves on the losing side of a reinforced two level game. This loss in parliamentary powers is not compensated at the European level, as at that level political authority is effectively left suspended between the national governments, who are unaccountable as a collective, and the European Commission, which lacks a political mandate of its own. Against this background, a final section identifies guidelines for organizing parliamentary accountability in settings, like EU economic governance, in which executive power has come to be shared across levels.
Public Relations in Service Sector and Corporate Image Management: A Research in Transportation Sector
Year: 2017

Because of the services having the features of being human centered, consumed when they are produced and not able to be stocked; the institutions should give more importance to the works of public relations, use the media communication intensively; maintain and improve their image they should do this permanently. The image of an institution that the companies and organizations reflect out, has a vital importance in its relations with the public. Public relations give reputation to the image of an institution. Public relations have the major responsibility in creation, protection, and consolidation of an institution's image. Under the scope of our work, it is discussed how the public relations studies; that we think it is not used intensively, affect the corporate image and especially on the necessity of public relations methods and techniques to be used by the enterprises to create a corporate image operating in service sectors. As a field research, the in depth interview was made with the Marketing Manager of Pamukkale Tourism in the transportation sector, which is one of the leading on road public transportation companies, on to what extent they use the advantage of public relations activities on creating a corporate image. As a result of research, we reached the conclusion that Pamukkale Tourism take the advantage of social media with public relations studies, especially considering the investments they made on social media, they used the public relations methods about customer satisfaction and providing a service quality and all of these studies affect the corporate image in positive frame.
Symbolic execution with existential second order constraints
Venue: ESEC/SIGSOFT FSE
Year: 2018

Symbolic execution systematically explores program paths by solving path conditions formulas over symbolic variables. Typically, the symbolic variables range over numbers, arrays and strings. We introduce symbolic execution with existential second order constraints an extension of traditional symbolic execution that allows symbolic variables to range over functions whose interpretations are restricted by a user defined language. The aims of this new technique are twofold. First, it offers a general analysis framework that can be applied in multiple domains such as program repair and library modelling. Secondly, it addresses the path explosion problem of traditional first order symbolic execution in certain applications. To realize this technique, we integrate symbolic execution with program synthesis. Specifically, we propose a method of second order constraint solving that provides efficient proofs of unsatisfiability, which is critical for the performance of symbolic execution. Our evaluation shows that the proposed technique (1) helps to repair programs with loops by mitigating the path explosion, (2) can enable analysis of applications written against unavailable libraries by modelling these libraries from the usage context.
'From Your Ever Anxious and Loving Father' Faith, Fatherhood, and Masculinity in One Man's Letters to His Son during the First World War
Year: 2020

In the early months of 1916, Charles Robb a retired shipping clerk in the East End of London, England, wrote a series of letters to his 19 year old son Arthur, an army private awaiting embarkation to the Western Front. Charles Robb was my great grandfather and Arthur Robb was my grandfather. The letters offer an intriguing glimpse of one man 'doing' fatherhood under conditions of traumatic separation and extreme anxiety. This paper presents an analysis of the letters from a psychosocial perspective, exploring the ways in which the writer exhorts his son to live up to the ideals of Christian manhood, while managing the anxiety of separation by presenting a reconstruction in language of the familiar world of home and church.
