description: This paper introduces a new way to correct the non-uniformity (NU) in uncooled infrared-type images. The main defect of these uncooled images is the lack of a column (resp. line) time-dependent cross-calibration, resulting in a strong column (resp. line) and time dependent noise. This problem can be considered as a 1D flicker of the columns inside each frame. Thus, classic movie deflickering algorithms can be adapted, to equalize the columns (resp. the lines). The proposed method therefore applies to the series formed by the columns of an infrared image a movie deflickering algorithm. The obtained single image method works on static images, and therefore requires no registration, no camera motion compensation, and no closed aperture sensor equalization. Thus, the method has only one camera dependent parameter, and is landscape independent. This simple method will be compared to a state of the art total variation single image correction on raw real and simulated images. The method is real time, requiring only two operations per pixel. It involves no test-pattern calibration and produces no "ghost artifacts".

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: The biorefinery is a system that uses as feedstocks biomasses and recover from these energy, fuel and chemicals. There are many processes considered in the biorefinery system, but in this thesis the biorefinery that uses as feedstock oil, in particular dedicated crops and waste vegetable oils were considered.
In the first part of this thesis the biodiesel production process was studied.
One possible route to produce biodiesel from waste oils (carachetrized by high concentrations of Free Fatty Acids, FFAs), is the use of a two steps process: an esterification reaction of FFAs with glycerol and a successive transesterification reaction with methanol of the whole mixture using a basic catalyst.
In this thesis the esterification step of FFAs with glycerol, in presence of a new acid heterogeneous catalyst based on sulfonated polymers with enhanced temperature resistance, was studied. The use of this type of catalyst has the advantage of using a relatively high temperature favouring the reaction by stripping of water formed during the esterification
The use of an acid catalyst that is able to tranesesterify the glycerides and to esterify the FFAs is onther way to obtained biodiesel from waste or non edible oils.
In this thesis the reactions of contemporany esterification  of FFAs and tranesterification  of glycerides  were studied using new homogeneous or supported homogneous  Zn(II) catalysts and a NbO2/SiO2  heterogeneous catalyst. The second part of this thesis was devoted to study of new catalysts for chlorination reaction of glycerol recovered from biodiesel production process.The behavior of three series of homologous catalysts, chloroacetic acid series (acetic acid, monochloroacetic, dichloroacetic and trichloroacetic acid), glycolic acid series (glycolic acid, di‐glycolic acid and thio‐glycolic acid) and amminoacid series (glutamic acid, aspartic acid and cysteine), were investigated for their activity and selectivity to produce dichlorohydrins, important intermediates for epichlorohydrin production. In the present study we  explored also a completely new class of catalysts for glycerol chlorination, represented by acyl chlorides, never reported in the literature. The catalysts studied are acetyl chloride, propanoyl chloride, adypoyl chloride, butandioil di-chloride,  propandioil di-chloride and phenylacetyl chloride and more precisely it is reported a comparison between the acyl chlorides respect to corresponding carboxylic acid. The influence of some reaction parameters are studied as for example the effects of the pressure on activity and selectivity. Finally I use acyl chloride in stoichiometric amount in order to open new opportunities for chlorination process of glycerol with hydrochloric acid performed in situ.

description: In the present thesis different classes of nanomaterials based on di-block copolymers (BCPs) have been studied, with the purpose to design, characterize and fabricate functional nanostructures to be used as active elements in selective sensing and/or biosensing devices with high sensitivity.
The work has been mainly focused on the creation of two classes of BCP based materials: nanocomposite materials, characterized by the selective inclusion of functional nanoparticles (NPs) in specific BCP nanodomanins, and nanoporous materials able to act as ideal support for the physical immobilization of specific biomolecules. Also, an explorative study regarding the use of BCPs as additives in photopolymerizable formulations has been conducted.
The spontaneous self-assembly of BCPs has been used to prepare a large number of tailor-made nanostructured materials, that can be used as nanoscopic device components, templates or active layers in biosensors. The obtained results have confirmed that the self-organization of  block copolymers offers a wide variety of methods for structuring and functionalizing materials at nanometric length scale. These methods that could overcome several of the intrinsic limitations of current top-down fabrication technologies.
Ganda also known as “Buganda”, “Luganda”, “Kiganda”

Publisher: name: Database of Religious History (DRH)
Year: 2018

description: This entry focuses on the Ganda society before King Mutesa's reign; during his reign, King Mutesa admitted Arab traders, received missionaries, and European contact was made. Prior to European contact and Christian/Muslim influence, the traditional Ganda (who refer to themselves as “Baganda”) religion was based upon a hierarchy of gods, ghosts, fetiches, and amulets. Religious beliefs were interwoven with political structure, so the Ganda religion is best described as coterminous with the society. Traditionally, the Buganda was one of the Lacustrine kingdoms in the Lake Victoria region of Africa, and was known for its dominant military power. Today, Buganda is one of the four provinces in Uganda, and is located on the northwest shores of Lake Victoria.

description: AbstractKing salmon is important for aquaculture in New Zealand, contributing significant economic value. Fish health is a priority for the industry, and the change in the health status of king salmon needs to be accurately detected at the earliest possible stage. Many factors affect the health of king salmon, such as temperature. Identifying the key features that influence health prediction is a crucial step toward achieving this goal. This study utilizes trial data collected by the Cawthron Institute, which includes diverse information on king salmon, such as blood biochemistry and hematology. We explore the data by employing statistical methods and feature selection techniques in machine learning to identify the most relevant features for king salmon health prediction, aiming to classify individuals as healthy or unhealthy with a small number of features. The results show that although the most efficient feature selection techniques on different datasets vary, overall, feature selection approaches can successfully identify relevant and informative features for king salmon health classification. Through the incorporation of a few selected features, the learned classifiers could still achieve statistically equal or better classification performance. This study not only contributes to the understanding of the health indicators of king salmon but also provides crucial insights into health prediction, which will be beneficial to the improvement of the health of king salmon, leading to the development of more effective management strategies for aquaculture.
Systematic Literature Review and Meta-Analysis to Estimate the Burden of Fatal and Non-Fatal Overdose Among Persons Who Inject Drugs.
Creators: name: Shealey, Jalissa
Publisher: name: Georgia State University
Year: 2021

description: Background. People who inject drugs (PWID) have elevated risk for infectious diseases, psychiatric disorders, non-fatal overdose, and most importantly fatal overdose. Due to stigma, cost, and generalizability limitations, the burden of fatal and non-fatal overdose within this population is difficult to measure. We conducted a systematic review and meta-analysis to estimate fatal and non-fatal overdose rates among PWID.
Methods. A comprehensive search of PubMed was conducted to identify studies published between January 2010 and August 2020 that reported a rate or period prevalence estimate of overdose among PWID living in OECD countries. Titles and abstracts were independently screened by four researchers. Studies eligible for full text review were double screened and evaluated using inclusionary criteria before three researchers independently extracted study data related to overdose and PWID. Rates of non-fatal and fatal overdose rates were pooled using meta-analysis and assessed for heterogeneity. National non-fatal overdose rates were estimated for selected countries, and meta-regression was performed to examine geographical differences associated with non-fatal overdose.
Results. Abstract screening and full text review of 2319 studies resulted in inclusion of 59 (2.5%) studies for meta-analysis. The mean non-fatal overdose rate was estimated as 30.22 per 100 PY (95% confidence interval [CI]: 22.2 – 41.1; 95% prediction interval [PI]: 4 – 230). The estimated mean fatal overdose rate was 1.17 per 100 PY (CI: 0.5 – 2.8; PI: 6 – 2129). Mean non-fatal overdose rates for Australia, Canada, and the United States were 12.27 per 100 PY, 28.98 per 100 PY, and 41.81 per 100 PY, respectively.
Conclusion. Despite increased public health focus and surveillance on non-medical drug overdose, overdose attributable to injection is not well understood and requires improved monitoring. This systematic review and meta-analysis revealed that a substantial population of PWID experience non-fatal overdose which has been shown to increase their risk for subsequent fatal overdose. To combat this critical public health issue, increased access to harm reduction programs is needed for PWID.

Type 2 hybrid effectiveness-implementation
Varenicline

description: With expanded and sustained availability of HIV treatment resulting in substantial improvements in life expectancy, the need to address modifiable risk factors associated with leading causes of death among people living with HIV/AIDS (PLWH), such as tobacco smoking, has increased. Tobacco use is highly prevalent among PLWH, especially in southern Africa, where HIV is heavily concentrated, and many people who smoke would like to quit but are unable to do so without assistance. SBIRT (Screening, Brief Intervention and Referral to Treatment) is a well-established evidence-based approach successful at supporting smoking cessation in a variety of settings. Varenicline is efficacious in supporting smoking cessation. We intend to assess the effectiveness of SBIRT and varenicline on smoking cessation among PLWH in Botswana and the effectiveness of our implementation.
A Descriptive Examination of the Prevalence of Asthma Education, Medication Use and Medical Outcomes among Children with Asthma in a Multi-Year Cross-Sectional Study
Creators: name: Coil, Eric
Publisher: name: Georgia State University
Year: 2021

description: INTRODUCTION:  Asthma is a chronic lifelong condition that cannot be cured; however, it can be effectively controlled in most cases with medication. One of the most significant asthma treatment challenges is the multi-factorial nature of the disease and the complexity of current treatment protocols which contribute to a lack of medication use and the need for ongoing asthma education.
AIM:  To examine (a) the prevalence of medication use and asthma education to the severity of asthma outcomes (b) whether any demographic characteristics are associated with differing rates of asthma severity, medication use and asthma education.
METHODS:  Datasets (National Health Interview Survey (NHIS) [2008, 2013, 2018]), were combined to increase the number of observations of sample children. Children below the age of 18 were the target population; children who were diagnosed with asthma within this group were the focus of the examination. An asthma severity scale was created as a proxy, based on asthma outcomes. A comparison of outcomes to rates of medical adherence and asthma education was conducted to determine the rates of each.
RESULTS:  Children with higher levels of asthma severity tended to have higher response rates for medication use as well as asthma education. Non-Hispanic black children had higher rates of severe asthma outcomes (8.27% [5.14%, 11.40%]) compared to non-Hispanic white children (3.32% [1.74%, 4.90%]).
 CONCLUSION: Race, age groups, mother’s education, income, and insurance status were all related with poor asthma outcomes, medication use, asthma education and access to medical services. While medication use and asthma education appear to be negatively associated with asthma severity in these cross-sectional data, a longitudinal study is needed to determine their true significance.

Zika Virus RNA Persistence in Municipal Wastewater and Surface Water
Creators: name: Hill, Cailee
Publisher: name: Georgia State University
Year: 2021

description: INTRODUCTION: Zika virus (ZIKV), an enveloped virus of the species Flavivirus, was historically, rarely associated with human infection and diseases, but that changed with large outbreaks in French Polynesia in 2013 and then Brazil in 2015. With approximately 80% of ZIKV infections being asymptomatic and a lack of adequate surveillance methods and healthcare access and resources, Brazil had challenges in determining the true burden of infection in affected communities. Though the COVID-19 pandemic has increased the evidence of the detectability of enveloped viruses in wastewater, but there are still research gaps regarding how environmental conditions may affect detection of enveloped viruses such as ZIKV.
AIM: The objectives of this study are to utilize wastewater-based epidemiological methods as a means to detect and evaluate the stability of ZIKV RNA in primary influent and surface water under different environmental conditions including temperature, water matrices, and inoculation concentrations.
METHODS: ZIKV MEX 1-44 was added to primary influent from a local municipal wastewater treatment plant and surface water from a local stream in Atlanta, Ga. Three experiments were conducted. to assess the detection and persistence of ZIKV RNA in different conditions including different inoculation concentrations, water conditions and temperature. RNA was extracted at days 0, 1, 3, 7, 14, 21, and 28 for all experiments. Digital droplet polymerase chain reaction (ddPCR) was used to quantify ZIKV RNA concentration. Log10 concentrations and Log10 reductions (Ct/C0) were calculated and graphed to compare ZIKV RNA decay over time under the different conditions.
RESULTS: ZIKV RNA was detected in all samples at all times, temperatures, and water matrices with ddPCR during the month-long experiment. Across experiments, ZIKV RNA degradation increased in surface water, at increasing temperatures, and at lower inoculation concentrations. The ZIKV RNA signal decayed most rapidly in surface water at 35°C, with little to no decrease observed at 4°C across water matrices.
DISCUSSION: ZIKV RNA is more environmentally stable than previously assumed. This study increased the body of evidence for the methods of detection and the stability of enveloped viruses, such as ZIKV, in various waters, portraying how environmental conditions may affect said stability. Cost-effective and wide-scale population level surveillance methods to detect ZIKV RNA in wastewater and environmental waters such as these, are of increasing importance to better understand the burden of ZIKV in a community and to monitor for not only ZIKV, but also other emerging and reemerging pathogens. Such methods have the potential to be utilized in low-resources settings, filling the gaps, and overcoming the challenges of clinical surveillance.
Toxicological Assessment of Aged Electronic Nicotine Delivery System Aerosols on Primary Human Small Airway Epithelial Cells
Creators: name: Jeon, Jennifer
Publisher: name: Georgia State University
Year: 2021

description: The emerging popularity of electronic nicotine delivery systems (ENDS) has increased safety concerns. ENDS aerosols contain numerous hazardous components including acetaldehyde, formaldehyde, and heavy metals along with various other chemicals. Recent studies showed ENDS use can cause various health risks including gastrointestinal, cardiovascular, neurological, and immune system impairment. Moreover, the long-term respiratory effects of ENDS use have not been fully evaluated. In this study, we hypothesized during normal consumer use ENDS device ageing occurs, which may alter the toxicological properties of emitted aerosols. We propose that the altered toxicological properties of ENDS aerosols may elicit reactive oxygen species (ROS), oxidative stress, cell viability reduction and DNA damage in human primary small airway epithelial cells (SAEC). We utilized a custom built 4-channel puffing machine and a novel condensation trap to automatically generate and monitor aerosols from a mod type ENDS manufactured by VooPoo® using tobacco–flavored e-liquid. ENDS aerosols samples (1-25), (101-126) and (201-226) puffs were collected in the fluorinated ethylene propylene (FEP) tube trap and extracted to be assessed with the in-vitro toxicological assays. Our results revealed that the VooPoo® ENDS device produce different sizes of nanoparticles ranging from 10nm to ~1micron during the device aging process. Increasing particle concentrations were observed throughout the aging process where puffs 1-25 emitted 1 µg/m3, puffs 101-126 emitted 4 µg/m3, and puffs 201-226 emitted 7 µg/m3. Along with the VooPoo® device aging process, the increasing levels of reactive oxygen species, glutathione level, and cellular viability reduction were observed. Moreover, a three-fold increase in DNA damage in SAEC was observed at puffs 201-226 aging stage compared to puffs 101-126 puff fraction. This work suggests ENDS aerosols become more hazardous during normal device usage, which may pose a threat to respiratory health.

description: Joint blind source separation (JBSS) is a powerful methodology for analyzing multiple related datasets, able to jointly extract sources that describe statistical dependencies across the datasets. However, JBSS can be computationally prohibitive with high-dimensional data, thus there exists a key need for more efficient JBSS algorithms. JBSS algorithms typically rely on numerical solutions, which may be expensive due to their iterative nature. In contrast, analytic solutions follow consistent procedures that are often less expensive. In this paper, we introduce an efficient analytic solution for JBSS. Denoting a set of sources dependent across the datasets as a “source component vector” (SCV), our solution minimizes correlation among separate SCVs by minimizing distance of the SCV cross-covariance’s eigenvector matrix from a block diagonal matrix. Under the orthogonality constraint, this leads to a system of linear equations wherein each subproblem has an analytic solution. We derive identifiability conditions of our solution’s estimator, and demonstrate estimation performance and time efficiency in comparison with other JBSS algorithms that exploit source correlation across datasets. Results demonstrate that our solution achieves the lowest asymptotic computational complexity among JBSS algorithms, and is capable of superior estimation performance compared with algorithms of similar complexity.

description: Climate emergency has led to the investigation of CO$_{2}$ valorization routes. A competitive process included in this framework is the catalytic CO$_{2}$ cycloaddition to epoxides, to produce cyclic carbonates. Halide-based Ionic liquids (ILs) have been postulated to be a competitive choice. Nevertheless, the structure-performance relation for different ILs is still a topic of debate, being the cation-anion dissociation constant a key descriptor. In this work, the ions effect is tackled by Molecular Dynamics (MD) simulations. Propylene oxide and carbonate force fields were tested and used for 1,2-epoxyhexane and hexylene carbonate force field construction, while ILs were modelled by the CL\&P force field. Solubilities in an epoxide-carbonate medium were tested for ILs composed of [$\mathrm{N4444^+}$] or [$\mathrm{N2222^+}$] cations combined with the halide anions: Iodide [$\mathrm{I^-}$], Bromide [$\mathrm{Br^-}$] and Chloride [$\mathrm{Cl^-}$]. Results showed that [$\mathrm{N2222^+}$] cation-based ionic liquids were insoluble in the epoxide/carbonate medium, whereas [$\mathrm{N4444^+}$] cation-based ionic liquids demonstrated diffusion. Reaction medium interactions were studied between key atoms for experimentally soluble ILs. It was found that cation-anion interaction follows the catalytic activity trend, being [$\mathrm{I^-}$] the halide anion less associated with ([$\mathrm{N4444^+}$], [$\mathrm{bmim^+}$] and [$\mathrm{emim^+}$]) cations. A correlation between the first peak integration of the radial distribution functions and the experimental yields (including [$\mathrm{N1111^+}$][$\mathrm{Br^-}$]) could be established with a regression coefficient of 0.86. Additionally, [$\mathrm{I^-}$] based ILs displayed a better interaction between the cation and the epoxide oxygen, phenomena linked to epoxide activation and intermediates stabilization.

description: Natural Language Processing (NLP) techniques are being used more frequently to improve high-tech Augmentative and Alternative Communication (AAC), but many of these techniques are integrated without the inclusion of the users’ perspectives. As many of these tools are created with children in mind, autistic adults are often neglected in the design of AAC tools to begin with. We conducted in-depth interviews with 12 autistic adults to find the pain points of current AAC and determine what general technological advances they would find helpful. We found that in addition to technological issues, there are many societal issues as well. We found 9 different categories of themes from our interviews: input options, output options, selecting or adapting AAC for a good fit, when to start or swap AAC, benefits (of use), access (to AAC), stumbling blocks for continued use, social concerns, and lack of control. In this paper, we go through these nine categories in depth and then suggest possible guidelines for the NLP community, AAC application makers, and policy makers to improve AAC use for autistic adults.
An Exploratory Epidemiological Analysis Investigating the Representativeness of Children with Likely Autism Served by State Early Intervention and Special Education Systems
Creators: name: Wang, Jia
Publisher: name: Georgia State University
Year: 2021

description: Autism Spectrum Disorder (ASD) is a developmental disability that occurs among people across different socio-demographic groups. According to the Centers for Disease Control and Prevention (CDC) estimate, nationally 1.9% of children in the USA were diagnosed with ASD in 2016. However, the diagnostic and identification of ASD vary greatly across states. Differences across states are likely to impact the found prevalence for children with ASD in those states, which can cause the potential number of missed ASD cases to vary. The purpose of this study is to develop a potentially missed ASD case metric from available school data and investigate the relationship between the missed case metrics and relevant county-level socio-demographic covariates. The study focuses on the relationship between potentially missed ASD and ten variables include states (Idaho, Mississippi, and California), primary care physicians per 100,000 (2017), mental health providers per 100,000 (2019), children in poverty per 100,000 (2018), uninsured children per 100,000 (2017), residential segregation rate between black and white (2014-2018), high school graduation per 100,000 (2016-2017), median household income (2018), child mortality per 100,000 (2015-2018), and the percent of rural population based on Census Population Estimates (2010). Results: Simple correlation and regression models displayed significant relationships between potential missing ASD and most predictors. However, after including states, many predictors are not significant anymore, suggesting that individual states are an important source of variance to consider for analysis of missed ASD. By adding interactions between continuous predictors and states into the multiple linear regression models, uninsured children and percent of rural populations show significant differences between states with predictors of the relationship to missing ASD cases. Future studies should consider linear mixed models for the analysis of missing ASD.

description: We present photometric observations of the BL Lacertae object S5 0716+714 with a temporal resolution of 120 s in the Sloan i' and r' bands. These observations were conducted using the Comet Search Program telescope at Xingming Observatory from 2018 December 22 to 2020 February 15, and more than 5600 effective images were obtained on each filter across 79 nights. Additionally, we compiled long-term variability data spanning 34 yr in the optical UBVRI bands. Using the power-enhanced F-test and nested ANOVA test, we found intraday variability (IDV) on 31 nights and possible IDV on 20 nights in the i' band. Similarly, IDV was detected on 35 nights in the r' band, while possible IDV was observed on 22 nights. The minimum variability timescale is 7.33 minutes, and the estimated black hole masses are (0.68- 5.12)*10^8 Msun. The spectral variability and long-term optical light curves reveal a bluer-when-brighter trend on intraday timescales. The long-term optical flux density and spectral index exhibit periodic variability with a timescale of about 1038 days. An anticorrelation between optical flux and spectral index was observed, with a time delay of -140 days. Variability across different optical bands exhibited a strong correlation, with no discernible time lag. From the IDV, spectral variability, correlation, and time delays between different bands, we conclude that these radiation characteristics may result from the shock-in-jet model scenario.

Risk Factors of Sexual Assault Victimization within the U.S. Military
Creators: name: Hebrank, Katherine
Publisher: name: Georgia State University
Year: 2022

description: INTRODUCTION: Sexual assault (SA) victimization affects thousands of service members in the military each year and identifying risk factors of SA is essential to inform prevention efforts.
AIM: To synthesize literature on SA within the military to determine risk factors of SA incidence.
METHODS: Risk factors from 6 epidemiological studies were compared via meta-analysis using R. Odds ratios and tests of heterogeneity were calculated to illustrate the collective odds of SA given each risk factor across the studies and to show variability. Odds ratios were calculated separately for risk factors only mentioned in one study.
RESULTS: Women (OR =16.37), persons reporting sexual harassment during service (OR = 14.54), persons with a SA history (OR = 3.99), enlisted rank (OR = 2.47), non-married persons (OR = 2) and persons with no college experience were at greater risk of SA (OR = 1.32). Being White was found to be a protective factor (OR = 0.76). Our descriptive analysis found that experiencing stalking (OR = 11.84), being a sexual minority (OR = 2.15) or transgender increased the risk of SA (OR = 1.91). However, transgender womxn were at lower risk of SA than transgender mxn (OR = 0.42).
DISCUSSION: It may be useful to develop tailored prevention programs for those identified as at risk according to our findings. Further, more needs to be done to address the environmental and cultural factors specific to the military that perpetuate SA incidence.
Factors Associated with Poisoning and Suicide-Related Diagnoses After a Sexual Assault
Creators: name: Bartlett, Alyssa
Publisher: name: Georgia State University
Year: 2022

description: Introduction: More than 43% of women report experiencing sexual violence during their lifetime. Experiencing SA, especially violent SA, is associated with depression, substance abuse, suicidal ideation, and suicide attempt. Receiving a SA medical forensic exam (SAMFE) in the emergency department is typically the first line of acute care after an assault, providing an opportunity for prescribing necessary medications, forensic evidence collection, and treating physical injuries. Little is currently known how procedures during the exam and characteristics of the SA itself predict suicidal behavior and overdoses after an assault.
Methods: Participants included women who received a SAMFE within 120 hours of an assault (n=239). Information on demographic characteristics, medications prescribed during their SAMFE visit, and SA characteristics as well as information on poisoning and suicide-related diagnoses were collected from the electronic medical record.
Analysis: An initial logistic regression was performed to assess whether receiving prescription psychiatric medication during SAMFE visits predicted suicide-related diagnoses. A latent class analysis was also performed to identify classes of assault survivors’ experiences. The identified classes were then assessed for differences in proportions of suicide-related and poisoning diagnoses in the year following the exam.
Results: Women who received psychiatric prescription medication during a SAMFE had 5.41 times greater odds of receiving a suicide-related diagnosis within one year (p=0.007). The latent class analysis identified two classes of assault severity among survivors. Survivors in Class 1 had more typically assaults, while survivors in Class 2 experienced more violent assaults with a higher probability of experiencing anal penetration, genital and non-genital injury, and weapon use. A two-proportion z-test found that Class 2 comprised a higher proportion of poisoning diagnoses in the sample (p=0.029).
Conclusion: These findings highlight the prescribing of psychiatric medication or documenting characteristics of severe SA as markers for suicide and self-harm interventions. Future studies should focus on developing these interventions for implementation in acute care settings and promote the ease of follow-up psychological care after an assault.

description: This paper presents a unified rank-based inferential procedure for fitting the accelerated failure time model to partially interval-censored data. A Gehan-type monotone estimating function is constructed based on the idea of the familiar weighted log-rank test, and an extension to a general class of rank-based estimating functions is suggested. The proposed estimators can be obtained via linear programming and are shown to be consistent and asymptotically normal via standard empirical process theory. Unlike common maximum likelihood-based estimators for partially interval-censored regression models, our approach can directly provide a regression coefficient estimator without involving a complex nonparametric estimation of the underlying residual distribution function. An efficient variance estimation procedure for the regression coefficient estimator is considered. Moreover, we extend the proposed rank-based procedure to the linear regression analysis of multivariate clustered partially interval-censored data. The finite-sample operating characteristics of our approach are examined via simulation studies. Data example from a colorectal cancer study illustrates the practical usefulness of the method.

description: Infection control of Nosocomial spread of viral illnesses has long been a challenge for the safety of healthcare workers (HCWs) and their patients. The ongoing pandemic caused by the Sars-Cov-2 (COVID-19) virus has highlighted the importance of providing HCWs with the proper personal protective equipment (PPE). This study aims to explore differences between the PPE combination effect on reducing virus penetration at different levels virus concentrations with the use of a novel aerosol generation system. The PPE combinations used in the study: N95 respirator + face shield, surgical mask + face shield, surgical mask + N95, N95 respirator, face shield. The results of the study show that PPE can reduce virus exposures at a higher rate than when no PPE was used. The N95 respiratory was the most effective at reducing viral exposures. The results from the study may offer further insight into the best application of PPE within a medical setting.
Kuy traditional religions also known as “Khamen-Boran, Kui, Kuy, Kuay, Kuoy, Soai, Soei, Suay, Suei, Sui, and Suoi”

description: Kuy is an ethnonym used for people who speak the Kuy language, which is from the Katuic group of the Austroasiatic family. The Kuy are known by different names across Thailand, Laos and Cambodia. Note that today there is ambiguity regarding how Kuy self-identify, which makes it difficult to define or measure their cultural practices with complete accuracy. The following map includes areas where traditional Kuy communities live.

description: This study explored inter-organizational relationships (IOR) between farmers and agri-food processors in Ghana and their relative effect on participating farmers’ performance. The IOR were organized into three broad types: governance (formal/informal); orientation (price/quality/quantity); and structure (direct-to-buyer/farmer-based organization (FBO)/agent). The study showed that about 44% of farmers participated in IOR, and 72% of them use direct-to-buyer relationships compared to 25% and 5% who use FBO and agent. The total exceeds 100% because some farmers used multiple IOR structures. Likewise, more than half of farmers involved in IOR use multiple orientations, with 29%, 81% and 54% of them using orientations involving quantity, quality, and price specifications, respectively. Formal governance IOR accounted for 31% of IOR by governance. On performance, the average farm income of farmers involved in IOR was GHS 3,947, which was 3.1 times higher than non-IOR farmers, and those with formal arrangements had 6.4 times higher average farm income than farmers in informal relationships. IOR with formal governance and quality-price orientation presented positive and statistically significant effects on marginal benefits while producer demographic and socio-economic characteristics did not. These results provide instruction for policymakers and practitioners in helping inform farmers’ participation in IOR that produce superior outcomes.

description: Increasingly, courses on Empirical Software Engineering research methods are being offered in higher education institutes across the world, mostly at the M.Sc. and Ph.D. levels. While the need for such courses is evident and in line with modern software engineering curricula, educators designing and implementing such courses have so far been reinventing the wheel; every course is designed from scratch with little to no reuse of ideas or content across the community. Due to the nature of the topic, it is rather difficult to get it right the first time when defining the learning objectives, selecting the material, compiling a reader, and, more importantly, designing relevant and appropriate practical work. This leads to substantial effort (through numerous iterations) and poses risks to the course quality. This chapter attempts to support educators in the first and most crucial step in their course design: creating the syllabus. It does so by consolidating the collective experience of the authors as well as of members of the Empirical Software Engineering community; the latter was mined through two working sessions and an online survey. Specifically, it offers a list of the fundamental building blocks for a syllabus, namely course aims, course topics, and practical assignments. The course topics are also linked to the subsequent chapters of this book, so that readers can dig deeper into those chapters and get support on teaching specific research methods or cross-cutting topics. Finally, we guide educators on how to take these building blocks as a starting point and consider a number of relevant aspects to design a syllabus to meet the needs of their own program, students, and curriculum.

description: The Fellahin of Egypt are indigenous rural villagers mostly living in the Nile Valley. "They are believed to be among the oldest farmers on earth whose highly productive agriculture, characterized by total reliance on irrigation and intensive labor, contributed to the rise of the ancient Egyptian civilization" (eHRAF Culture Summary). Given Egypt's proximity to the origin and development of Christianity, the Fellahin culture cannot be considered isolated from Christian influence. Notably, the majority of Fellahins are Muslims.
