An Extended Review on Story Test Driven Development

This paper presents a systematic review of studies on story-test driven development. Our findings suggest that there are many lessons learned papers that provide anecdotal evidence about the benefits and issues related to the story test driven development. We categorized these findings into seven themes: cost, time, people, code design, testing tools, what to test and test automation. We analyzed research papers to find out how many of these anecdotal findings were critically examined by researchers and analyzed the gaps in between. The analysis can be used by researchers as a ground for further empirical investigation.
Antioxidant molecule useful in the stabilization of nanoparticles in water suspension

ABSTRACT The preparation of antioxidant-coated magnetic nanoparticles (MNPs) has been studied to improve their biocompatibility, i.e. reducing negative side effects. The theoretical study was focused on the interaction of gallic acid (GA) with ionic iron at the surface of nanoparticles that increased reactivity and favors the uniform dispersion in water of magnetic nanoparticles and the interaction with other molecules of biomedical interest. Experimentally, we worked with an optimal method of coating the MNP with GA at 80°C which led to fine granulation highlighted by TEM, preservation of good crystallinity, proven by XRD as well as magnetic properties suitable for biomedical applications based on magnetically targeted guidance. The study of nanotoxicity was focused on the fate of MNPs eliminated in the biosphere, so the influence on photosynthesis in seedlings in early ontogenetic stages was sought. The small variation, with a positive trend, of the efficiency of photosynthesis was correlated with the balancing of the toxic effects, of ROS generation catalyzed by iron ions from the MNP surface by means of the antioxidant character of GA.
Understanding needs of stakeholders and outcomes desired from a home-based intervention program for “difficult to treat” schizophrenia and related disorders: A qualitative study

Background: We aimed to understand the needs of service users – families and patients with schizophrenia and related disorders, and mental health professionals (MHPs) and expectations from a home-based psychosocial intervention program in Indian setting. Materials and Methods: We conducted four focus group discussions (FGDs) with families, patients with schizophrenia and related disorders and MHPs. Two FGDs were conducted with families and one each with the patients and MHPs. Participants in families and MHP group were asked about their primary concerns in caring for the patients, perceived needs of patients and the areas that can be targeted through a home-based psychosocial intervention program. All FGDs were audio-recorded and verbatim transcribed. Content analysis of the data was done to obtain a final list of needs and expected outcomes from a psychosocial intervention supported by families. Results: Six key priority needs were identified for intervention: medication adherence, activities of daily living, promoting physical health, engagement in meaningful work, building of social and support networks and information about all aspects of illness. Priority outcomes identified by MHPs were mostly clinical like symptom reduction, fewer rehospitalisation while families and patients focused more on psychosocial outcomes, such as improvement of wellbeing, having relationships, engagement in meaningful activities, better organization of the day, increased self-respect, reduced stress, lesser interference, and critical comments. All groups suggested that book or mobile app or video could be used. Conclusion: This qualitative study shows that while both clinicians and service users consider recovery from schizophrenia and related disorders to be important, they differ on what they prioritise.
Modeling the use of air-injection for emissions reduction in a direct-injected diesel engine

This study investigates the effect of air-injection during the late combustion period produced by an air-cell on emissions from a direct injected diesel engine. The engine considered is a Caterpillar 3401 test engine which was modeled with an air-cell included as part of the piston geometry. A version of the KIVA-II code with updated submodels for diesel combustion and emissions was modified to allow for geometries with walls interior to the domain. This modified version of KIVA-II was then used to model an air-cell equipped diesel engine for four different air-cell configurations. Of the four air-cell configurations simulated, one proved successful in reducing the predicted engine emissions by more than a factor of two while simultaneously reducing NOx by a slight amount, thus moving the engine off its particulate-NOx tradeoff curve defined by varying the fuel injection timing. This air-cell configuration demonstrates that air-injection during the late combustion period can be effective at reducing engine emissions. The other three air-cell configurations simply moved the engine along its particulate-NOx tradeoff. However, this study highlights potential difficulties for designing an air-cell equipped engine. Namely, the large effect produced by the interaction of the turbulence and the in-cylinder flow in the proximity ofmore » the air-cell inlet on the overall operation of the air-cell. « less
NEXT-GENERATION CATALOGUES: HOW ARE THE ACADEMIC LIBRARIES IN KENYA FARING?

The library catalogue has changed over the years from a card catalogue to its electronic successor, the Online Public Access Catalogue (OPAC), to what is called the next-generation library catalogue, sometimes referred to as the library 2.0 catalogue or â€˜the third-generation catalogueâ€™. The purpose of this study was to investigate the current state of catalogues in academic libraries in Kenya and to evaluate whether these libraries have incorporated features of the next-generation catalogues in their OPACs. The study applied a checklist of features commonly identified as characteristics of the next-generation catalogue to examine whether the OPACs of university libraries in Kenya are comparable to the next-generation library catalogue. The findings of the study showed that libraries in Kenya have made some progress towards transforming their OPACs to the next-generation catalogue but have not reached the ideal. None of the OPACs has all the features evaluated. Progress has been made with features, such as enhanced content, simple keyword search and faceted navigation. However, none of the catalogues has federated searching capabilities. The study also found out that close to half of the libraries which have their OPACs available online are using Koha as their Library Management System (LMS). This article provides valuable information for library policy makers interested in modernising their catalogues or acquiring discovery tools for their institution. The article may also be a useful tool for evaluating OPACs modules of the integrated LMS, especially for libraries that are in the process of selecting a suitable LMS.
Health Management Occupations During COVID-19: Experiences of Older African Americans With Multimorbidity

Older African Americans with multimorbidity are at an especially high risk of adverse outcomes due to synergistic risks conferred by age, chronic disease burden and social determinants of health. Chronic condition self-management is one way older African Americans can use health management occupations and exercise agency to reduce their risk of becoming severely ill, and during the ongoing pandemic, of COVID-19 infection. The objective of this study was to understand how the COVID-19 pandemic shaped health management occupations of older African Americans. In-depth qualitative interviews were conducted with 30 African Americans aged 65 and older who reported having two or more chronic conditions. Data were analyzed using thematic analysis. Data suggest how key health management occupations (accessing care; managing medications, nutrition, and physical activity; and social and emotional health promotion and maintenance) were utilized and also shaped by the pandemic. Another key finding was perceived benefits of the pandemic on health and well-being.
Taiwanese engineering students’ self-efficacy and academic performance

Despite the popularity and the importance of MOOCs in global education in recent years, they have not become the focus of self-efficacy studies. In addition, most available MOOC research resides in Western economies, not in Asian countries. No studies up to this point have explored the change in engineering student self-efficacy before and after they finish a MOOC or the relationship between engineering students’ self-efficacy and academic performance in a MOOC learning environment. This present study examined if there were any changes in the self-efficacy levels of a group of students before and after they attended a blended MOOC on English Technical Writing skills. It explored the relationship between self-efficacy and academic performance and looked for possible differences in self-efficacy and academic performance with respect to different demographic variables. A Paired-samples t-test helped to measure differences in self-efficacy scores at the beginning and end of the course. Pearson correlation was conducted to examine if self-efficacy predicted students’ course grades at the end of the course. Descriptive analysis, t-test, and ANOVA were used to measure the differences between the mean scores of self-efficacy and academic performance regarding different demographic variables. Results showed that students became more self-efficacious after they attended the blended MOOC. Self-efficacy significantly predicted academic performance. Students who reported higher self-efficacy levels gained better scores. Participants differed significantly in their self-efficacy and academic performance in relation to age group, English proficiency level, and educational level. Suggestions for future research are made based on the results of the study.
Perceptions of Telemedicine and Costs Incurred by a Visit to a General Infectious Diseases Clinic: A Survey

Abstract Background The costs of attending in-person general infectious diseases clinics and preferences for visit type (telemedicine vs in-person) are not well known. We aimed to measure the time-related, monetary, social, and societal costs associated with travel to an in-person clinic visit and to assess patients’ preferences, questions, and concerns regarding telemedicine. Methods Patients (≥18 years, living ≥25 miles from clinic at time of clinic visit) were recruited for this survey study from the general infectious diseases (ID) clinic at Washington University from June 2019 to February 2020. We calculated time and money potentially saved by telemedicine, as well as carbon dioxide emissions, with the assistance of Google Maps (low/high estimates). We also determined patient preferences regarding telemedicine for ID care. Results Seventy-five patients completed the study. The round-trip mean travel distance was 227.2 ± 142.6 miles, mean travel time was 3.6 ± 2.0 hours to 4.5 ± 2.3 hours (low and high estimates from Google Maps), travel costs were $131.34 ± $82.27, and mean carbon dioxide emissions were 91.79 ± 57.60 kg. Fifty-eight patients (77.3%) said they would be willing to have a telemedicine visit in the future, and 30 (40.5%) said they would rather have had their visit the day the survey was completed as a telemedicine visit. Conclusions Telemedicine has the potential to significantly reduce patient costs, both monetary and time-related, and offers substantial environmental benefits, while being an acceptable method of care delivery to most patients at a general ID clinic.
Employee Motivation, Job Reengineering, and Perceived Job Satisfaction: A Quantitative Correlational Approach

This quantitative research investigated the correlation between employee motivation, job reengineering, and the perception of job satisfaction among the civilian employees of the Department of Defense located in Washington, D.C., United States. The theoretical foundation for the study was rooted in Deci and Ryan's (1985; 2000) self-determination theory of motivation. The researcher utilized a non-experimental correlational research design and an appropriate non-probability convenience sampling method to collect data from fifty-five (55) participants. The multidimensional work motivation, job diagnostic, and the job satisfaction scales were used to measure the variables. Non-parametric tests were used to measure the correlation between the variables and three hypotheses were tested. The results showed a strong and positive relationship exists between employee motivation, job reengineering, and the perception of job satisfaction. These findings suggest that business leaders and human capital managers of private and government enterprises may use the study as a focal point to understand a person-job fit, establish lean organizational efficiencies, and formulate strategies to improve motivation and reduce turnover. Keywords: Emotional Intelligence, Employee Motivation, Job Design, Job Reengineering, Job Redesign, Job Satisfaction, Metacognitive Abilities, Perception, Perception of Job Satisfaction, And Self-Determination Theory
Employee Performance Management Scenarios in the Era of Work from Home

Almost all companies in the world have implemented the work from home (WFH) system in the last two years with the aim of limiting community activities in suppressing the spread of Covid-19. Interestingly, both companies and employees also feel benefited from this system, one of which for employees is that they can arrange work places and positions so that they can increase work motivation, for companies they can reduce company costs such as office rental costs. This study aims to analyze the effect of work from home on work motivation, job satisfaction and employee performance, the effect of job satisfaction on employee performance, the effect of work motivation on employee performance, and to create scenarios for managing employee performance. The study was conducted in October 2021 on 86 respondents who work at PT XYZ Jakarta, Surabaya and Medan branches. They were selected by volunteer sampling with the criteria of employees who have worked for at least one year with the level of position as supervisor and staff who have been assigned to work from home. Data were collected by distributing online questionnaires, then analyzed using descriptive analysis and SEM-PLS with the SmartPLS application and TAIDA analysis to determine managerial implications. The results showed that Work from Home had a direct and positive significant effect on Work Motivation and Job Satisfaction but not significant on Employee Performance, Job Satisfaction had a direct and positive effect on Employee Performance, and Work Motivation had no direct effect on Employee Performance. The form of managerial implications that can be carried out for managing employee performance is by using a hybrid work system, namely employees can work with a mixed system between work from home and work in the office. Keywords: job satisfaction, employee performance, work motivation, work from home.
A study of sand-asphalt mixtures: a constitutive model based on a thermomechanical framework and experimental corroboration

A Study of Sand-Asphalt Mixtures: A Constitutive Model Based on a Thermomechanical Framework and Experimental Corroboration. (August 2006) Parag Ravindran, B.E. , Bangalore University; M.S.,Texas A&M University Chair of Advisory Committee: Dr. K. R. Rajagopal Asphalt bound mixtures have been put to diverse uses. The complicated nature of the material and the demanding conditions under which it is used preclude complete solutions to questions on load bearing capability under field conditions. In proportion to the quantity of its usage and in acknowledgment of modeling complexity, the material has been interrogated by many researchers using a variety of mechanical tests, and a plethora of linear viscoelastic models have been developed. Most models are intended to account for specific classes of problems. This work addresses the conspicuous absence of systematic documentation of normal forces generated as a result of shear. The normal force generated during simple shear is a clear indication of the nonlinear nature of the material. The effect of fillers (hydrated lime and limestone), air voids, aggregate gradation, asphalt source and step loading on normal force generation during torsion is experimentally investigated. Based on experimental evidence, a non-linear thermomechanical model for sandasphalt mixtures based on the idea of multiple natural configurations is developed. The model accounts for the fact that the mixture has a natural configuration (stressfree configuration) which evolves as it is subjected to loads. Assumptions are made regarding the manner in which the material stores and dissipates energy. A key
Comparison of compartmentalized dynamic model, HYDRUS, and curve number methods for estimating drainage from windrow composting pads

Design of containment facilities for runoff from windrow compost pads lacks suitable runoff prediction models for the unique surface consisting of gravel overlying compacted subsoil material. Models used were the curve number, a commercially available numerical computer model (HYDRUS R ©2-d), and a compartmental model developed on the MatlabSimulink R ©platform based on rainfall-runoff data. The curve number model was based on infiltration, antecedent rainfall, and the percentage of pad coverage and led to a predicted vs. observed collection pond volume with a Percent Root Mean Squared Error (% RMSE) of 0.61 % compared to maximum pond volume. The prediction was relatively insensitive to deviation from the literature recommended value of 75. HYDRUS 2D applied vertical and lateral flow aspects to infiltration, storage, and subsurface transport, improving pond volume prediction with an %RMSE = 0.65 %. The Compartmental Model separately estimated outputs for infiltration, lateral seepage, and overland flow with an % RMSE = 0.76 %. Information from the compartment model can be used to develop an instantaneous unit hydrograph of compost pads and future applications for porous pavements.

Composition, texture, sensorial quality, and biological activity after in vitro digestion of durum wheat pasta enriched with carrot waste extract encapsulates

Abstract Aim of this research was to evaluate durum-wheat pasta enriched with encapsulated carrot waste extracts in oil, obtained by freeze drying (FDE) or spray drying techniques (SDE). Five pastas (control, enriched with 10% FDE, or 10% SDE, or 20% FDE, or 20% SDE) were evaluated for furosine, carotenoids, tocols, colour, in vitro bioactivities, cooking performance, texture and sensory quality. The encapsulates added to the enriched pastas α-carotene (0.58–1.24 mg/kg), β-carotene (1.43–3.29 mg/kg), cis-β-carotene (0.51–1.11 mg/kg) and total tocols (10.9–33.6 mg/kg). The carotenes were stable and the tocols diminished (-13%) during pasta manufacturing; both decreased (2–18% and 4–15%, respectively) during cooking, but they were still more abundant in the enriched pastas. Antioxidant, anti-hyperglycaemic, anti-inflammatory and anti-proliferative activities after in vitro digestion of cooked pastas improved, while sensory acceptability of control and 10% enriched pastas were similar. The encapsulates addition significantly improved the nutritional and technological qualities of durum-wheat pasta.

Recent Developments on the Broadband Heating Rate Profile Value-Added Product

Objectives of the BBHRP VAP The Atmospheric Radiation Measurement (ARM) broadband heating rate profile (BBHRP) value-added product (VAP) was initiated in order to build upon and broaden in a variety of directions the fruitful long-standing series of measurement-model comparisons of clear-sky spectral surface radiances at Southern Great Plains (SGP; Turner et al. 2003, Brown et al. 1998). The objectives of this effort are: • Extend existing measurement-model closure studies to irradiance comparisons involving: − shortwave spectral region − cloudy conditions − the spatial and temporal scale corresponding to a General Circulation Model (GCM) 'grid cell' at SGP − top of the atmosphere (TOA) fluxes • For use by single-column models (SCMs), compute heating rate profiles based on in situ measurements and using validated radiative transfer model
ACCEPTANCE AND USE OF INFORMATION TECHNOLOGY BY SENIOR EXECUTIVES

It is becoming increasingly imperative for managers to track the process that ultimately leads to the adoption and effective use of new technology. The study explores an extension of technology adoption model (TAM) for senior executives. The TAM is modified with additional constructs of Perceived Enjoyment (PE), Perceived Risk (PR) and Self-Efficacy (SEf.). An addition of Cultural Influence (CI) and Social Influence (SI) is also being made as a direct determinant of Behavioral Intention (BI). The study is empirically validated using a field survey through a questionnaire. Employing a sample of 431 senior executives it develops and tests a modified TAM within the Pakistani culture. Regression as well as Partial Least Square (pls) is used for data analysis. Regression analysis is done using SPSS version 12.0 while pls analysis is done using Visual Parital Least Square (VPLS) version 1.04. The results indicate that the modified TAM works well. The findings are important because they are different and distinct from Western cultures. The modified TAM shows that dependent variables attitude toward using computer has explained 63% variance while BI has explained 54% variance.
