QoS/QoE-based Wi-Fi Network Trust and Reputation

In recent years, Wi-Fi technologies have become very popular and the trend is continuing to climb. Unfortunately, there is a risk to use Wi-Fi networks in range because there is no way to select trustworthy Wi-Fi networks. In this thesis, we focus on ways that can help users to choose the best Wi-Fi network for their needs. In order to help the user to choose the best network, our solution allows the users to rate the networks that they have used. It also checks that their assessments reflect the true network quality that they have experienced by measuring and certifying the quality of service such as delay, jitter and packet loss. The measuring process follows an innovative protocol that certifies the measurement in all cases but one. We mitigate this remaining case thanks to trust and reputation management.
Correlates of Principals Attachment Styles, Leadership Styles and Principals’ Effectiveness: The Case of Secondary Schools in Ethiopia

The purpose of this study was to assess the relationship between attachment style, leadership styles and perceived leaderships effectiveness in government secondary schools in Ethiopia. Survey research design was used. Seventeen schools were selected randomly. Using Yamana’s (1967) formula 209 teachers were selected from sample schools proportionally using systematic random sampling technique. The Relationship Questionnaire (RQ) for attachment style and The Multifactor Leadership Questionnaire (MLQ) were used to measure leadership style and leaders’ effectiveness. The research findings indicated that there is statistically significant relationship between transformational leadership and secure; Positive weak relationship was observed between preoccupied and transactional; Fearful attachment behavior of the leader is also moderately correlates with laissez-faire leadership style; there was a significantly moderate relationship between principals’ effectiveness and secure attachment style. It was also found that there was positive but moderate level of relationship between leadership style and overall attachment styles and strong correlation between attachment styles and leadership style with perceived leadership effectiveness. A regression analysis result indicated that the four attachment style statistically significant predictor of leadership styles (transformational, transactional and laissez-faire) even if the predictive power is low. It is also recommended that future research could do similar study using a different population in different setting, with different leadership style and different type of attachment styles to determine if the findings are reliable.
In beta : an action research journey of developing music communities as an app creator

Music is an essential part of people? s every day lives, accompanying them as they go about their daily routines, and it can be experienced in almost any context now; which allows us to capture, categorize and reconstruct the activities and memories that shape our personal, social and cultural lives. In this thesis, the area of concern that I explore is the creation of an online community based on people? s experiences with music. Because of the personal nature of the topic and the tendency for the information to change over time, the methodology I chose was action research, specifically Checkland and Holwell? s (1998) FMA methodology. Using this approach, I investigate the different kinds of technology that can be used to build the foundations of the community and which factors are most salient to facilitate member growth. I also examine the effects that user-generated content has on the participation within an online community and the technological features that aid in facilitating this. I discovered that trust is a vital part of an online community because it fosters cooperation between members through visible pro-social behaviour, and that a combination of ease of use, usefulness and the size of the community could influence the participation and activity of users in generating content. I also found that the development cycle for Internet software never ends, thus permanently in beta, as there will always be improvements to the community based on user feedback. I analyzed the data by comparing key metrics such as membership and user-generated content growth for each community to see if the learning and reflections from previous cycles helped improve community participation in the current cycle. The results I obtained and method I used in the thesis demonstrated my contribution to the body of knowledge in using action research theory, specifically the FMA methodology, to investigate, learn and develop an online community as an app creator. I argue that action research can help guide academic-based startups in much the same way as other startup frameworks and this point is one of the focuses for future research on this topic.
Evaluation of clinico-demographic and laboratory profile of children admitted with enteric fever: A retrospective observational study

Aim: To evaluate the clinical and laboratory findings in children admitted with enteric fever. Material and Methods: This retrospective observational study was conducted in the Department of Pediatrics of a tertiary care hospital in North India. Medical records of children admitted with a diagnosis of enteric fever (Widal positive or blood culture positive) within a period of one year from July 2018 to June 2019 were retrieved and analyzed. Total 110 children aged below 14 years with enteric fever were included in this study. In each case, the clinical and demographic details and laboratory investigations reports including the blood culture reports and antibiotic sensitivity pattern were collected from the hospital records and analysed. Results: Out of 110 cases, 75 cases (68.18%) were males and 35 cases (31.82%) were females. Most of the cases were aged between 5 and 10 years (50%). The most common symptom was fever (100%), followed by anorexia (64.55%), vomiting (48.18%), pain abdomen (19.09%), diarrhoea (13.64%), headache (11.82%), and cough (8.18%). The most common sign we observed was coated tongue in 50.90%, hepatomegaly in 44.55%, splenomegaly in 20.90%, hepatosplenomegaly in 12.73% of cases and pallor in 7.27% of cases. Anemia was found in 23 (20.90%) cases, leucopenia and leucocytosis was observed in 39 (35.45%) cases and 16 (14.55%) cases, respectively. Differential leukocyte count was suggestive of neutropenia in 45 (40.90%) cases and neutrophilia in 30 (27.27%) cases. Thrombocytopenia was present in 18 (16.36%) cases. SGOT levels were elevated (>200IU/ml) in 17 (15.45%) cases and SGPT (>200IU/ml) in 15(13.63%) cases. Blood culture was positive for Salmonella Typhi in 7 (6.36%) patients with all isolates sensitive to third gen cephalosporins and fluoroquinolones. 75 (68.89%) cases had a hospital stay of more than 7 days and 33 (30%) required a change of antibiotic to fluoroquinolones. Conclusion: Typhoid fever is a common paediatric illness with high morbidity and having varied clinical and laboratory presentation. Blood culture though considered standard is rarely positive, mostly due to previous oral antibiotic therapy. This major public health issue can be tackled by bringing awareness among people regarding disease transmission and its various preventive measures.
Factores de riesgo asociados al consumo de sustancias en mujeres víctimas de maltrato en contexto de pobreza.

El trabajo analiza la relación entre el padecimiento de sucesos vitales estresantes y el consumo excesivo de alcohol y drogas en 136 mujeres víctimas de violencia de género de Nicaragua. Los datos se obtuvieron a partir de una entrevista estructurada heteroaplicada diseñada para este fin, que recoge sucesos vitales estresantes padecidos por las víctimas a lo largo de su vida. Los resultados muestran que quienes padecieron distintos episodios de violencia desde la infancia consumieron alcohol y drogas en exceso. Además, el mayor predictor para el consumo de alcohol y drogas se encuentra entre quienes padecieron abuso sexual antes de los 18 años. Por otra parte, los análisis Odds Ratio indican un aumento del riesgo para el consumo de sustancias cuando el abuso se produjo a edades tempranas. Pese a la relevancia para la salud de las víctimas, existen pocos dispositivos en Nicaragua con los que atender a las víctimas de violencia de género hacia procesos de recuperación, sobre todo para quienes han desarrollado estrategias de afrontamiento relacionados con el consumo excesivo de sustancias. The work analyzes the relationship between the suffering of stressful life events and the excessive consumption of alcohol and drugs in 136 women victims of gender violence in Nicaragua. The data was obtained from a heteroapplied structured interview designed for this purpose, which collects stressful life events suffered by the victims throughout their lives. The results show that those who suffered different episodes of violence since childhood consumed alcohol and drugs in excess. In addition, the greatest predictor for alcohol and drug use is among those who suffered sexual abuse before age 18. On the other hand, the Odds Ratio analyzes indicate an increased risk for the consumption of substances when the abuse occurred at an early age. Despite the relevance for the health of the victims, there are few devices in Nicaragua with which to assist victims of gender violence towards recovery processes, especially for those who have developed coping strategies related to excessive substance use.

Time-Varying Term Structure of Oil Risk Premia

We develop a framework to estimate time-varying commodity risk premia from multi-factor models using futures prices and analysts’ forecasts of future prices. The model is calibrated for oil using a 3-factor stochastic commodity-pricing model with an affine risk premia specification. The WTI oil futures price data is from the New York Mercantile Exchange (NYMEX) and analysts’ forecasts are from Bloomberg and the U.S Energy Information Administration. Weekly estimations for short, medium, and long-term risk premia between 2010 and 2017 are obtained. Results from the model calibration show that the term structure of oil risk premia moves stochastically through time, that short-term risk premia tend to be higher than long-term ones and that risk premia volatility is much higher for short maturities. An empirical analysis is performed to explore the macroeconomic and oil market variables that may explain the stochastic behavior of oil risk premia, showing that inventories, hedging pressure, term premium, default premium and the level of interest rates all play a significant role in explaining the risk premia.
Some unsteady aerodynamics relevant to insect-inspired flapping-wing micro air vehicles

Flapping-wing micro air vehicles, based on insect-like apping, could potentially ll a niche in the current market by o ering the ability to gather information from within buildings. The aerodynamics of insect-like apping are dominated by a large, lift-enhancing leading-edge vortex (LEV). Historically, the cause and structure of this vortex have been the subject of controversy. This thesis is primarily intended to provide insight into the LEV, using computational uid dynamics coupled with validating experiments. The problem is simpli ed by breaking down the complex kinematics involved in insect-like apping and examining only a part of these kinematics; rstly in 2D, before progressing to 3D sweeping wing motions. The thesis includes discussion of published literature in the eld, highlighting gaps and inconsistencies in the current knowledge. Among the contributions of this thesis are: descriptions of the e ects of changing Reynolds number and angle of attack for 2D and 3D ows; clari cation of terminology and phenomenology, particular in the context of 2D ows; and detailed descriptions of the development and structure of the LEV in both 2D and 3D cases, including discussion of Kelvin-Helmholtz instability. The issues of Strouhal number, delayed leading-edge separation, dynamic stall and the Wagner e ect are also considered. Generally, the LEV is shown to be unstable in 2D cases. However, in 3D cases the LEV is seen to be stable, even if Reynolds number is increased. The stability of the LEV is found to be critically dependent on wing aspect ratio.
Puerarin Improves Dexamethasone-Impaired Wound Healing In Vitro and In Vivo by Enhancing Keratinocyte Proliferation and Migration

The delayed and impaired wound healing caused by dexamethasone (DEX) is commonly reported. Puerarin, the major isoflavone found in Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep promoted the wound healing process in diabetic rats. However, the effects and underlying mechanisms of puerarin on DEX-impaired wound healing have not been investigated. This study examined the potential uses of puerarin in upregulating keratinocyte proliferation and migration in dexamethasone (DEX)-suppressed wound healing model. The effects of puerarin on wound healing in vivo were investigated by taking full-thickness 5 mm punch biopsies from the dorsal skin of BALB/c mice and then treating them topically with 0.1% DEX. For the in vitro study, DEX-treated HaCaT cells were used to examine the effects of puerarin on DEX-induced keratinocyte proliferation and migration and the mechanisms of its action. Puerarin, when applied topically, accelerated the wound closure rate, increased the density of the capillaries, and upregulated the level of collagen fibers and TGF-β in the wound sites compared to the DEX-treated mice. Puerarin promoted the proliferation and migration of keratinocytes by activating the ERK and Akt signaling pathways in DEX-treated HaCaT cells. In conclusion, puerarin could be effective in reversing delayed and disrupted wound healing associated with DEX treatments.
Fall Detection using Human Skeleton Features

Falls are one of the leading causes of death and serious injury in people, especially for the elderly. In addition, falls accidents have a direct financial cost for health systems and, indirectly, for the productivity of society. Among the most important problems in fall detection systems is privacy, limitations of operating devices, and the comparison of machine learning techniques for detection. This article presents a fall detection system by means of a k-Nearest Neighbor (KNN) classifier based on camera-vision using pose detection of the human skeleton for the features extraction. The proposed method is evaluated with UP-FALL dataset, surpassing the results of other fall detection systems that use the same database. This method achieves a 98.84% accuracy and an F1-Score of 97.41%.
Lime Application Rates on Selected Soil Chemical Properties of Acidic Soils

: Liming has been recently started to amend acidic soils in the study area but meager information is available about effects of Dejen lime on soil properties. The objective of this study was to investigate the application dose effect of locally available liming material on selected chemical properties of Dystric Nitisol. Soil samples received 0, 1.1, 2.2, 3.3 and 4.4 t ha -1 Dejen lime and incubated for one month at constant moisture and temperature. Finally, its pH, exchangeable acidity, Al, Ca, Mg, K, Na, Mehlich 3 and water soluble P were estimated. Lime rates significantly (p < 0.01) increased soil pH, exchangeable Ca, Mehlich 3 and water soluble P but exchangeable acidity and Al significantly (p < 0.01) decreased. Application of 2.2 t ha -1 Dejen liming material increased soil pH and available P by 0.6 units and 9.2 mg kg -1 , respectively but exchangeable acidity decreased by 0.72 cmol (+) kg - 1 . Thus, application of > 2.2 t ha -1 lime alleviate acidity related problem of the soil for crop growth but supplementary nutrient (mainly P) is required for optimum crop yield. Application of 2.2 t ha -1 Dejen liming material substantially improves soil acidity related problems but supplementary soil nutrient is essential to increase crop yield in the study area.
FREEWAY WORK ZONE ACCIDENT CHARACTERISTICS

This article describes accident characteristics on freeway facilities where work zone traffic control procedures were of a high standard in terms of current state-of-the-art. Data is based on the results of a 3-year study of traffic control needs at freeway work zones. The study is summarized with emphasis on accident characteristics. The two most disruptive types of work zone traffic control were crossovers and lane closures. The study revealed the following: (1) The high involvement of trucks at night in accidents at crossovers is an indication that, for them at least, the driving task is more demanding here than at other work-site zones or on the Turnpike in general, resulting in more driver errors; and (2) The high injury rates corresponding to accidents in the bi-directional zones suggest that driver errors in the zone have more severe consequences than driver errors at other sections within work sites or on the Turnpike in general.
Application of the microbial decay factor to maintain chloramine in large tanks

Microbial acceleration of chloramine decay (including nitrification) exacerbates the difficulty of maintaining an adequate disinfectant residual in chloraminated systems with long retention times. An adaptive management strategy based on the microbial decay factor (Fm) was developed to improve chloramine residual in a service reservoir (tank). The reservoir studied has a capacity of 404 ML and is not mechanically mixed. It undergoes continuous chemical, physical, and microbial stratification in summer but in winter is only microbially stratified. At the end of summer 2002‐03 (southern hemisphere), signs of severe nitrification were observed. After careful consideration of control options, serial dilution was adopted, particularly in winter. The Fm value resulting from this serial dilution was predictable from previous measurement of Fm in the reservoir and its inflow. Subsequently, an adaptive control strategy to maintain low Fm ensured that the reservoir was clear of severe nitrification for the next two years of evaluation.
Link Prediction and the Evolution of Communities on Twitter

This research is about the influence of link prediction on the evolution of communities on Twitter. We collected tweets from three technology micro-bloggers who led us through their followings and tweets to tens of thousands of unique users over several weeks. We analyzed conventional and alternative information streams for these micro-bloggers based on URLs embedded in their tweets and in tweets of followees and followees-of-followees. We model users based on the most recent URLs embedded on their tweets and the latest users they follow, from which we infer links and extract semantic entities that are indicative of their interests. Furthermore, we propose a pipeline of methods for user modeling and personalization of communities of interest on Twitter. We test the performance of different organizational principles in community design, including the principles of hierarchy, user interests and the baseline follower mechanism on Twitter, which is based on user intuitions. The goal of this thesis is to create a better notion of community by automatically calculating adaptive and personalized structures of followees that produce highly interesting content. Designing communities in this way is use- ful because it enables people to know in which community they are organized during a given period of time and because it enables community-based recommendations. Furthermore, designing communities based on organizational principles enables their automatic construction. Currently, communities are manually constructed by users through a tedious process of following and unfollowing which is based on disconnected user intuitions. We investigate whether it is possible to infer links between Twitter users who are not explicitly connected on Twitter and explore whether such automatically inferred social networks would allow for improving content recommendations on Twitter.
Knowledge, Attitude, and Practices Towards Added Sugar Consumption among Undergraduate Female Students in Madinah, Saudi Arabia: A Cross-Sectional Study

Background: Intake of added sugar among populations in developed countries is linked to the increased prevalence of many non-communicable diseases; however, data regarding added sugar intake in developing countries are still lacking. This study aimed to evaluate knowledge, attitude, and practices towards added sugar intake and the associations with nutrient intake and weight status. Methods: This cross-sectional study was conducted among 190 healthy undergraduate female students of Taibah University, Madinah. Demographics, dietary intake, and anthropometrics (height, weight, and waist circumference (WC)) were collected during face-to-face interviews. Results : Even though 55.8% of students (n=106) were aware about the health consequences of excessive intake of added sugar, only 32.6% (n=62) made an effort to reduce their added sugar intake. Nine percent of students (n=16) consumed carbonated soft drinks daily, while 16.1% of students (n=30) consumed fruit drinks daily. Eighty-two percent (n=155) of the sample exceeded the recommendation of added sugar of <5% of total energy intake. Students who exceeded the recommendation of added sugar consumed lower quantities of protein, iron, and vitamin D. Added sugar intake was linked to nutrient intake, but not the weight status. Conclusions : Our findings indicated excessive intake of added sugar among young females. The observed inverse relationship between added sugar and macro- and micronutrient intakes highlight the urgent need for expanded efforts to limit the added sugar and to improve dietary quality of young population in Saudi Arabia.
