Abstract:
The objective of this work was to evaluate the production of cherry tomatoes in protected environments composed of different photoselective screens. The work was conducted in June / July 2018. The treatments consist of different types of protected environments: open sky, black screen (mesh for 30% shade); white fabric (mesh for 20% shade); blue screen (mesh for 20% of shade) and red screen (mesh for 20% of shade). The experimental design was a randomized block with four replicates, ten plants per experimental plot. The following analyses were performed on cherry tomatoes: leaf number, stem diameter, shoot height, root length, total fresh matter, shoot fresh matter, fresh root matter, shoot dry matter, root, chlorophyll a and chlorophyll b. The black shading, white photoselective, blue photoselective and red photoselective screens did not influence the number of leaves, stem diameter, shoot height, root length, total fresh matter, fresh shoot matter, aerial shoot dry matter, root dry matter, chlorophyll a and chlorophyll b. The red photoselective screen showed superiority in the fresh matter of the root of the other treatments.

Abstract:
Stomoxys calcitrans is considered as a major pest of livestock worldwide. Insecticides have been extensively used to control this pest but resistance to these chemical compounds is now reported in many countries. Therefore, a more sustainable and efficient control is needed. Seven different types of blue screens, with reflectances around 460 nm, were tested during summer 2016 in southwestern France to evaluate their attractiveness and their specificity for stable flies. Height of the screen and orientation (east or west) of a blue screen were also considered. High levels of S. calcitrans captures were recorded during this study (from 141 to 7301 individuals per blue screen and per day) whereas the numbers of tabanids and pollinator insects remained extremely low (less than 10 individuals per screen and per day). No significant difference in attractiveness has been shown between the different types of blue screens. The lower half of the blue screens caught significantly more stable flies (70%) than the higher half (30%). The “east” side of the screen attracted 60% of stable flies but this was not significantly different from the west side. These results are highlighting the interest in these blue polyethylene screens for controlling stable flies in cattle farms, in comparison with more expensive blue fabrics.

Abstract:
Abstract. The fluorescent dye Brilliant Sulfaflavine (BSF, CAS 2391-30-2) was investigated to determine its photo-stability and recovery on five spray deposition collectors: white plastic plate, nylon screen, and stainless steel (SS) screens of three mesh sizes (40, 60, and 80). The photo-stability of the deposited dye was determined by measuring the variance in fluorescence intensity after daylight exposure. The recovery rates were investigated with statically dispensed droplets and dynamically discharged droplets. In addition, droplet penetration through the screen collectors and the amount of unrecovered dye on reprocessed collectors were assessed to better understand the differences in dye recovery rates among different collector types. Photo-degradation tests verified that all collector types were insignificant in fluorescence degradation (<3.1%) after 120 min of solar exposure. Nylon screens had the lowest dye recovery rate (87.0%) for statically dispensed droplets, whereas plastic plates and SS screens recovered more than 90% of deposited dye. For dynamically discharged droplets, the 60-mesh and 80-mesh SS screens recovered more than 70% of the deposited dye, whereas nylon screens showed less than 50% recovery rate. These results were substantiated visually with a high-speed imaging system that detected droplets penetrating more frequently through screens with larger mesh openings. Throughout ten continuous reprocessing cycles of the fluorimetry test, the fluorescence intensity on reprocessed nylon and 80-mesh SS screen collectors increased by 16.8% and 12.7%, respectively, while there was less than 1% change in fluorescence intensity on the 40-mesh and 60-mesh SS screens. These results were clarified through dye residue verification using digital image analysis. Keywords: Fluorescence intensity, Photo-degradation, Recovery rate, Spray deposition assessment, Stainless steel screen.

Abstract:
Time on screens (screen time) on multiple digital devices (computers, mobile phones, tablets, television screens, etc.) due to varied motivations (work, leisure, entertainment, gaming, etc.) has become an integral part of population behaviour. However, a significant evidence gap exists in screen time accumulated over ubiquitous mobile devices such as smartphones. This study aimed to develop an accurate, reliable and replicable methodology to derive objective screen time (i.e., screen-state) from all types of citizen-owned smartphones. A convenience sample of 538 adults (≥18 years) from two largest urban centres in Saskatchewan, Canada (Regina and Saskatoon) was recruited in 2017 and 2018. Participants used a custom-built smartphone application to provide objective and subjective data. A novel methodology was developed to derive objective screen-state, and these data were compared with subjective measures. The findings showed that objective screen-state from smartphones can be derived and assessed across a range of cut-points that take into consideration varied measurement errors. When objective measures were compared with subjective reporting, the results indicated that participants consistently underreported screen time. This study not only provides a methodology to derive objective screen-state from ubiquitous mobile devices such as smartphones but also emphasises the need to capture context via subjective measures.

Abstract:
Illusory self-motion (vection) can be generated by visual stimulation. The purpose of the present study was to compare behavioral vection measures including intensity ratings, duration, and onset time across different visual display types. Participants were exposed to a pattern of alternating black-and-white horizontal or vertical bars that moved either in vertical or horizontal direction, respectively. Stimuli were presented on four types of displays in randomized order: (a) large field of view dome projection, (b) combination of three computer screens, (c) single computer screen, (d) large field of view flat projection screen. A Computer Rod and Frame Test was used to measure field dependence, a cognitive style indicating the person’s tendency to rely on external cues (i.e., field dependent) or internal cues (i.e., field independent) with respect to the perception of one’s body position in space. Results revealed that all four displays successfully generated at least moderately strong vection. However, shortest vection onset, longest vection duration, and strongest vection intensity showed for the dome projection and the combination of three screens. This effect was further pronounced in field independent participants, indicating that field dependence can alter vection.

Abstract:
There is an increasing trend of mental health problems both globally and in Sweden. Moreover, in recent decades there has been an increase in screen time among adolescents. The present study aimed to examine the associations between screen time (i.e., smartphone, computer, and TV) and mental health problems among adolescents in Västmanland and to investigate if the association was different due to gender. A quantitative method with a cross-sectional design was applied. The study used secondary data from the Survey of Adolescent Life in Västmanland 2020. The sample consisted of 3880 adolescents from 9th grade in compulsory school and 2nd grade in upper secondary school. The results showed that high screen time on smartphone was associated with an increased probability for mental health problems in the total sample. In contrast, screen time on TV and computer showed no significant association with mental health problems. Thus, smartphone use was a significant contributor to mental health problems. Furthermore, for girls, high screen time on the smartphone, computer, and TV was associated with increased probability of mental health problems, whereas no significant associations were found among boys. In brief, this study’s findings suggest developing Swedish guidelines to regulate harmful effects from screen time.

Abstract:

With increased dependence on computer-based standardized tests to assess academic achievement, technological literacy has become an essential skill. Yet, because students have unequal access to technology, they may not have equal opportunities to perform well on these computer-based tests.

The researcher had observed students taking the STAR Reading test (Renaissance Learning, 2009) and noticed a variance in scores in relation to classroom performance. The researcher intended, therefore, to explore variables that may affect the performance of students on a computer-based reading assessment. The researcher tested two different technology-related variables as students took a summative exam, the STAR Reading test. The purpose of this study was to explore how changes in visual stimuli affected the process of reading and student reading behavior. This quantitative study sought to ascertain whether changing the computer read-out to a black screen with white lettering made a difference in student engagement and comprehension among students in grades two through six during a computer-based adaptive test.

The research site was one K-6 elementary school in a large suburban school district. The participants of the study were 316 children in grades two through six. One hundred and sixteen students were randomly sampled for student engagement data analysis. The researcher conducted a stratified random process to further select data for analysis. Students were exposed to both color display background variables throughout the study process. Teacher observers collected tallies on student engagement behaviors during the test-taking process.

The researcher calculated the mean level of student engagement on each of five observed behaviors. The researcher also collected reading comprehension data for five subsequent benchmark sessions throughout the year. The engagement results of this study failed to support the hypothesis, which stated that elementary student behaviors during testing would verify a measureable difference in engagement when either a black or white display screen was presented. The results of the reading comprehension test also failed to support the hypothesis, which stated that there would be a measureable difference in elementary students' scores while taking computer-based tests when the computer screen was set to either black or white background.

Abstract:
Dans cette thèse, nous présentons l’étude et la réalisation de micro-capteurs pour les systèmes de gestion des risques naturels. Le cahier des charges était centré sur les possibilités de concevoir des capteurs de polluants pour la surveillance des zones lagunaires dans le sud montpelliérain. Ces capteurs devaient être conçus dans une démarche « faible coût », résistant aux contraintes du milieu et pouvant communiquer et temps réel. Le premier chapitre s’appuie sur une étude bibliographique des différentes méthodes de mesures qui peuvent être utilisées pour faire de la détection de polluants et des matériaux potentiels pour réaliser le capteur. La technique de mesure la plus appropriée pour répondre aux deux premiers points du cahier des charges s’appuie sur la réalisation de transducteurs acoustiques à base de PZT en envisageant un processus technologique basé sur la technique de sérigraphie. Après avoir justifié notre choix de la technique de dépôt par sérigraphie, nous avons détaillé dans le second chapitre le processus technologique, en commençant par la réalisation de l’encre PZT, puis par le dessin des masques et pour finir nous avons détaillé les étapes de dépôt et de fonctionnalisation des transducteurs sur substrat d’alumine et sans substrat. A partir de ces premières réalisations, nous avons présenté les moyens et outils de caractérisation nécessaires pour pouvoir évaluer les différentes étapes du processus technologique mis en place, avec une attention particulière portée sur la qualité du matériau PZT et sur ses propriétés piézoélectriques. Il s’agit d’une part d’études morphologiques (images MEB, profilomètre) et structurelles (diffraction X, EDX) et d’autre part de la mesure des grandeurs piézoélectriques et diélectriques (piézomètre, analyses spectrales et d’impédances). Dans le troisième chapitre nous avons abordé le volet système de cette étude, avec la réalisation de prototypes basés sur les transducteurs sérigraphiés développés au chapitre 2. Les capteurs réalisés ont été testés et étalonnés avec des solutions d’éthanol et de toluène. Pour cela les capteurs sérigraphiés ont été testés sur des bancs expérimentaux afin de valider la technique de la mesure du temps de vol des ondes acoustiques. Dans l’optique de la miniaturisation et de l’intégration du système nous avons mis en place une électronique de commande embarquée à l’aide d’un module dédié. Enfin, pour pouvoir affiner les mesures, nous avons vu que nous pouvions envisager de croiser/corréler plusieurs paramètres. C’est ainsi que nous avons développé un capteur sérigraphié pour la mesure de la conductivité électrique en milieu aquatique. A partir des premiers résultats expérimentaux obtenus nous avons pu valider le principe de la méthode. Dans le quatrième et dernier chapitre de ce manuscrit, nous avons présenté les toutes premières études et réalisations sur la technologie LTCC. En reprenant les paramètres du processus utilisés lors des dépôts sur substrat d’alumine, nous avons réalisé et caractérisé des transducteurs déposés sur une feuille de céramique LTCC. Les premières caractérisations morphologiques et piézoélectriques sont encourageantes et les premiers tests acoustiques ont montré que la génération d’ondes acoustiques était tout à fait possible et qu’une utilisation en vue de la réalisation de capteurs de polluants était envisageable avec cette technologie. Enfin, nous avons pu réaliser une première structure 3D intégrant une cavité d’analyse. Là encore les débuts sont très prometteurs même s’il reste encore beaucoup de travail de « réglage » pour améliorer cette technologie. De plus, cette première réalisation 3D, ouvre de nombreuses perspectives au niveau de l’équipe en vue du développement de nouveaux capteurs
In this thesis, we introduce the study and implementation of micro-sensors for natural risk management systems. The specification focused on the possibilities to develop a pollutant sensor capable of detecting the presence of hydrocarbons in the lagoon environments of southern Montpellier.These sensors should be designed in a "low cost" gait, resistant to environmental constraints and able to communicate in real time. The first chapter is based on a bibliographical study of the different methods of measurement that can be used for the detection of pollutants and potential materials for making the sensor. The most suitable measurement technology to answer the first two points of the specification is based on the implementation of acoustic transducers made from PZT with a technological process using the screen-printing technique. After justifying our choice of screen-printing deposition technique, we have detailed in the second chapter the technological process: first with the achievement of PZT ink, then with the masks design, and finally with the steps deposition and functionalization of transducers on alumina substrate and without substrate. From these first achievements, we have submitted the means and characterization tools needed to evaluate the different steps of the technological process set up with a focus on the quality of the PZT material and its piezoelectric properties. It is first about morphological (SEM images, profilometer) and structural (XRD, EDX) studies, and then about the measurement of piezoelectric and dielectric values (piezometer, spectral and impedance analyses). In the third chapter we discussed the sensor, with the production of prototypes based on screen-printed transducers developed in Chapter 2. The sensors were tested and calibrated with solutions of ethanol and toluene. For this, the screen-printed sensors were tested in experimental benches to validate the measurement technique of the acoustic waves time of flight. In view of the miniaturization and the integration of the system, we have set an electronic control board with a dedicated module. Finally in order to improve the measurements, we have shown that we could consider crossing/correlating several parameters. Thus, we have developed a screen-printed sensor for the measurement of the electrical conductivity in aquatic environment. From the first experimental results we validated the principle of the method. In the fourth and final chapter of this manuscript, we presented the first studies and achievements on the LTCC technology. By repeating the process parameters used during deposition on alumina substrate, we realized and characterized transducers placed on on a LTCC ceramic sheet. The first morphological and piezoelectric characterizations are encouraging, and the first acoustic tests have shown that the generations of acoustic waves, and a use for the production of sensors of pollutants were possible with this technology. Finally we have been able to achieve a first 3D structure incorporating an analysis cavity. Here again, results are very encouraging, although "adjustments" are needed to improve the technology. Also this 3D realization opens up many opportunities for the team to develop new sensors

Abstract:
This study examined the readability of fonts. More specifically, it investigated how four different fonts effected both reading rate and reading comprehension. The typefaces Georgia, Verdana, (which, according to their designers, optimize onscreen readability) Times, and Arial (both designed for digital output to hard copy) were displayed as treatments both on a computer screen and on paper. The purpose of the study was to determine whether sans serif and serif typefaces optimized for on-screen viewing significantly improve reading rate and reading comprehension. Comparisons were made among the typefaces using a categorical independent variable postmeasure-only research design to determine the level of dependent variables (rate, comprehension). The group means of each of twelve treatment groups (N=264) were analyzed using analyses of variance to determine if either of the variables (presentation mode or font) had a statistically significant effect upon reading rate and/or reading comprehension of a sample taken from a population of subjects attending a midwestern state university. No significant difference was found among reading speed or reading comprehension scores of subjects tested who read text which was typeset in any of the four typefaces. However, significant difference was found between the presentation modes used in the experiment. Since it was found that 8-bit on-screen text was not significanly more readable than 600dpi text on paper, and 1-bit onscreen text was found to be significantly less readable than onscreen text and 600dpi text on paper, this research concludes that for purposes of ease of readability, onscreen text is better suited to be rendered as 8-bit onscreen text than 1-bit on-screen text. Also, the findings indicate that 8-bit on-screen text was not found to be significantly less readable than 600dpi text on paper. Also, due to the various typefaces currently being used in digital typography and the differing presentation media, further exploration of the readability of on-screen text should examine more fonts and screen display variables.

Abstract:
To ensure that photovoltaics contributes significantly to future world energy production, the cost per watt of producing solar cells needs to be drastically reduced. The use of n-type silicon wafers in conjunction with industrial print technology has the potential to lower the cost per watt of solar cells. The use of n-type silicon is expected to allow the use of cheaper Cz substrates, without a corresponding loss in device efficiency. Printed metallisation is well utilised by the PV industry due to its low cost, yet there are few examples of its application to n-type solar cells. This thesis explores the use of n-type Cz silicon with printed metallisation and diffusion from printed sources in creating industrially applicable solar cell structures. The thesis begins with an overview of existing n-type solar cell structures, previous printed thick film metallisation research and previous research into printed dopant sources. A study of printed thick-film metallisation for n-type solar cells is then presented, which details the fabrication of boron doped p-type emitters followed by a survey of thick film Ag, Al, and Ag/Al inks for making contact to a p-emitter layer. Drawbacks of the various inks include high contact resistance, low metal conductivity or both. A cofire regime for front and rear contacts is established and an optimal emitter selected. A study of printed dopant pastes is presented, with an objective to achieve selective, heavily doped regions under metal contacts without significantly compromising minority carrier lifetime in solar cells. It is found that heavily doped regions are achievable with both boron and phosphorus, but that only phosphorus paste was capable of post-processing lifetime compatible with good efficiencies. The effect of belt furnace processing on n-type silicon wafers is explored, with large losses in implied voltage observed due to contamination of Si wafers from transition metals present in the belt furnace. Due to exposure to chromium in the belt furnace, no significant advantage in using n-type wafers instead of p-type is observed during the belt furnace processing step. Finally, working solar cells with efficiencies up to 16.1% are fabricated utilising knowledge acquired in the earlier chapters. The solar cells are characterised using several new photoluminescence techniques, including photoluminescence with current extraction to measure the quality of metal contacts. The work in this thesis indicates that n-type printed silicon solar cell technology shows potential for good performance at low cost.

Abstract:
Principal aims were to investigate long-term outcomes from T2DM and IGT screening, examine morphological and biochemical phenotypes of screened subjects, comparing White Europeans (WE) with South Asians (SA), and emerging therapies including basal insulin analogues in T!DM and meglitinides in T2DM and their place in management. Following adjustment for age, sex and ethnicity, no significant difference in mortality microvascular or macrovascular outcomes were detected between known and screened T2DM after ten years. Findings were limited by few events and relatively short follow-up. These data may be useful in power calculations for longer randomised controlled trials. Body fat is higher in SA than WE for given BMI and increases with worsening glucose tolerance. Bioelectrical impedance analysis and skinfold thickness are less sensitive and specific with increasing body fat regardless of ethnicity and gender. Ethnicity and BMI, but not age, predicts total and abdominal fat using DEXA scanning. After adjustment for age, BMI, WHR, gender, smoking and drug history, no differences between SA and WE for adiponectin and resistin were detected. Leptin is predicted by age, gender and smoking in WE but only gender in SA. BMI predicts hsCRP in both groups while age and smoking predicts TNFalpha in SA. Longitudinal cohort studies are needed to determine impact of interventions on risk markers in different ethnic groups. Insulin glargine results in a small but significant glycaemic improvement without significantly increased hypoglycaemia, weight gain or reduced patient satisfaction when used in a basal bolus regimen with aspart compared with NPH insulin in T1DM. In a six month randomised study, four different dual oral combinations including nateglinide, pioglitazone, metformin and gliclazide, in early T2DM result in significant glycaemic improvement without increasing hypoglycaemia or patient dissatisfaction with no significant differences between groups. Longer RCT are required to determine duration of glycaemic improvement with each combination.

Abstract:
Various types of electrochemical sensors based on the inhibition of butyrylcholinesterase (BChE) have been presented for the analysis of organophosphates (OPC). A special design of thick film sensors and electrochemical detector for cholinesterases assay and their inhibitors in aqueous samples has been developed. For this assay, thiol sensitive sensors based on screen printed graphite electrode modified with nanoparticles of manganese dioxide were used. High sensitivity of manganese dioxide modified thick film sensors towards thiocholine and therefore low detection limit of BChE (1 pM) enabled their use for subnanomolar detection of an organophosphate pesticide diazinon, and other irreversible inhibitors of BChE. This work also presents modern innovative approach for the analysis of BChE by Raman spectroscopy. New SERS-substrates based on silver paste for sensitive quantification of BChE activity were obtained, characterized and applied to thiocholine detection, with LOD (TCh) being 260 nM. Real samples of human plasma were analyzed; a good correlation between spectrophotometric detection and Raman detection was shown. The developed technique is inexpensive and easy-to-use and has promising potential for analysis of OPC.

Abstract:
AbstractOral cancer develops in precursor lesions referred to as the group of premalignant disorders (PMDs) by the World Health Organization (WHO). Some lesions are relatively common affecting between 1 and 5% of the population (leukoplakia) and may resemble benign and prevalent mucosal disease. These lesions pose a risk for malignancy that is independent of tobacco or alcohol, with a wide range of transformation rates between 13 and 70%. The commonest types are white patches (leukoplakia), red patches (erythroplakia) and submucous fibrosis. Knowledge of the patterns of clinical presentation of PMDs is important in order to screen patients effectively, identifying those who benefit from a close observation, those who require from targeted biopsy and those who may be safely followed up in primary care. We describe clinical features of the most well-documented premalignant disorders discussing lesion-specific risk predictors and treatment options. We also present a brief outline of the less prevalent group or premalignant systemic conditions including those that predispose to the development of mucosal squamous carcinoma and those that associate with the development of cutaneous squamous carcinoma. Genetic pathways involved in the development and progression of PMDs are outlined, and finally, we describe best practices for carrying out a diagnostic tissue biopsy.

Abstract:
Due to Covid-19 disease, which has an increasing negative impact on the world day by day and has been classified as a pandemic by the World Health Organization, continuing education remotely at various levels has brought with it very important discussions. Perhaps, one of the most crucial of these is the increased screen usage times. The intensive use of digital media in all areas of our social life has brought to mind the frequent handling of the time spent by children and young people in front of the screen in the pre-pandemic period by academia and nonacademies. However, with the pandemic, the education process is carried out entirely in distance; in addition to that, with the elimination of the need for socialization, entertainment and information due to screens, which became the sole medium for socialization, entertainment and information, has further increased the importance of studies that reveal the effect of screen usage time on children and young people. From this perspective, our study is based on Sonia Livingstone's approach to addressing screen use not only through "risks" but also through "opportunities". When it comes to screen use and "screen time", parents and teachers evaluate screen time within the framework of technological addiction; they did not focus on the nature of screen use and how to convert it into technological competence. The main purpose of this study is to reveal the approaches of parents and teachers regarding screen times of high school students. In this context, the literature within the framework of "screen time", "technological addiction" and "technological competence" has been scanned for the research part of the study, in-depth interviews were conducted with the parents and teachers of students of different types of high schools throughout Istanbul. Due to the pandemic conditions during our time, the interviews were conducted digitally through a questionnaire; different questionnaire have been prepared for teachers and families. The findings obtained as a result of in-depth interviews were evaluated with six main headings. Headings are as foolows: screen times of young people, risks that young people may face during media use, parents' perception of technological proficiency, teachers' perception of technological proficiency, parents' approaches to screen time of young people and teachers' approaches to screen time. It is hoped that the study will contribute to the literature on the axis of digital technologies and education.

Syvash, Kateryna. AUDIENCE FEEDBACK AS AN ELEMENT OF PARASOCIAL COMMUNICATION WITH SCREEN MEDIA-PERSONS. Ivan Franko National University of Lviv, February 2021. http://dx.doi.org/10.30970/vjo.2021.49.11062.

Full text
Abstract:
Parasocial communication is defined as an illusory and one-sided interaction between the viewer and the media person, which is analogous to interpersonal communication. Among the classic media, television has the greatest potential for such interaction through a combination of audio and visual series and a wide range of television content – from newscasts to talent shows. Viewers’ reaction to this product can be seen as a defining element of parasociality and directly affect the popularity of a media person and the ratings of the TV channel. In this article we will consider feedback as part of parasocial communication and describe ways to express it in times of media transformations. The psychological interaction «media person – viewer» had been the focus of research by both psychologists and media experts for over 60 years. During the study, scientists described the predictors, functions, manifestations and possible consequences of paracommunication. One of the key elements of the formed parasocial connections is the real audience reaction. Our goal is to conceptualize the concept of feedback in the paradigm of parasocial communication and describe the main types of reactions to the media person in long-term parasocial relationships. The research focuses on the ways in which the viewer’s feedback on the television media person is expressed, bypassing the issue of classifying the audience’s feedback as «positive» and «negative». For this purpose, more than 20 interdisciplinary scientific works on the issue of parasocial interaction were analyzed and their generalization was carried out. Based on pre­vious research, the types and methods of feedback in the television context are separated. With successful parasocial interaction, the viewer can react in different ways to the media person. The type of feedback will directly depend on the strength of the already established communication with the media person. We distinguish seven types of feedback and divide them into those that occur during or after a television show; those that are spontaneous or planned; aimed directly at the media person or third parties. We offer the following types of feedback from TV viewers: «talking to the TV»; telling about the experience of parasocial communication to others; following on social networks; likes and comments; imitation of behavior and appearance; purchase of recommended brands; fanart.

Abstract:
This report, prepared for The Jim Henson Company, shares findings of a sub-study investigating the types of support parents and caregivers need when navigating and using the second-screen Splash and Bubbles for Parents app. This study originated from a prior field study finding indicating families would benefit from support around the app since it represents a new kind of digital tool. In partnership with local Public Broadcasting Service (PBS) stations, we provided parents and caregivers more detailed support around the features of the app. Based on survey and interview findings, parents and caregivers found the app helpful for supporting their children’s science learning, thus validating the field study findings. We also found that all sections of the app were used and could help promote conversations between parent/caregiver and child. Moreover, families expressed choosing to use a specific app section when they felt it was more relevant or developmentally appropriate for their child.

Abstract:
Background Diabetes mellitus (DM) and depression are important comorbid conditions that can lead to more serious health outcomes. The American Diabetes Association (ADA) supports routine screening for depression as part of standard diabetes management. The PHQ2 and PHQ9 questionnaires are good diagnostic screening tools used for major depressive disorders in Type 2 diabetes mellitus (DM2). This quality improvement study aims to compare the rate of depression screening, treatment, and referral to behavioral health in adult patients with DM2 pre and post-integration of depression screening tools into the electronic health record (EHR). Methods We conducted a retrospective chart review on patients aged 18 years and above with a diagnosis of DM2 and no initial diagnosis of depression or other mental illnesses. Chart reviews included those from 2018 or prior for before integration data and 2020 to present for after integration. Sixty subjects were randomly selected from a pool of 33,695 patients in the clinic with DM2 from the year 2013-2021. Thirty of the patients were prior to the integration of depression screening tools PHQ2 and PHQ9 into the EHR, while the other half were post-integration. The study population ranged from 18-83 years old. Results All subjects (100%) were screened using PHQ2 before integration and after integration. Twenty percent of patients screened had a positive PHQ2 among subjects before integration, while 10% had a positive PHQ2 after integration. Twenty percent of patients were screened with a PHQ9 pre-integration which accounted for 100% of those subjects with a positive PHQ2. However, of the 10% of patients with a positive PHQ2 post-integration, only 6.7 % of subjects were screened, which means not all patients with a positive PHQ2 were adequately screened post-integration. Interestingly, 10% of patients were treated with antidepressants before integration, while none were treated with medications in the post-integration group. There were no referrals made to the behavior team in either group. Conclusion There is no difference between the prevalence of depression screening before or after integration of depression screening tools in the EHR. The study noted that there is a decrease in the treatment using antidepressants after integration. However, other undetermined conditions could have influenced this. Furthermore, not all patients with positive PHQ2 in the after-integration group were screened with PHQ9. The authors are unsure if the integration of the depression screens influenced this change. In both groups, there is no difference between referrals to the behavior team. Implications to Nursing Practice This quality improvement study shows that providers are good at screening their DM2 patients for depression whether the screening tools were incorporated in the EHR or not. However, future studies regarding providers, support staff, and patient convenience relating to accessibility and availability of the tool should be made. Additional issues to consider are documentation reliability, hours of work to scan documents in the chart, risk of documentation getting lost, and the use of paper that requires shredding to comply with privacy.

Abstract:
This report prepared for The Jim Henson Company shares findings of a field study examining the promise of the Splash and Bubbles for Parents app, a second-screen digital resource designed for parents and caregivers to support young children’s learning of ocean science. The study conducted in 2020 involved a two-group, quasi-experimental design in which family participants were randomly assigned to either the intervention condition (who watched the show and used the app) or the comparison condition (who watched the show but did not have access to the app). Findings from this study provided information about how the app supported families to talk about science together; what science concepts and practices children learned through engaging with the app and related science activities; and how families shifted their attitudes, beliefs, or practices around science and media. Another finding highlighted parents and caregivers’ need for support around ways to engage with and use the app given that this represents a new type of digital tool.

Full text
Abstract:
Cationic polypeptide proteins found in the seeds of the tropical plant Moringa oleifera have coagulation efficiencies similar to aluminum and ferric sulfates without their recalcitrant nature. Although these proteins possess great potential to augment or replace traditional coagulants in water treatment, harvesting active protein from seeds is laborious and not cost-effective. Here, we describe an alternative method to express and secrete active M. oleifera coagulant protein (MO) in Bacillus subtilis. A plasmid library containing the MO gene and 173 different types of secretory signal peptides was created and cloned into B. subtilis strain RIK1285. Fourteen of 440 clones screened were capable of secreting MO with yields ranging from 55 to 122 mg/L of growth medium. The coagulant activity of the highest MO secreting clone was evaluated when grown on Luria broth, and cell-free medium from the culture was shown to reduce turbidity in a buffered kaolin suspension by approximately 90% compared with controls without the MO gene. The clone was also capable of secreting active MO when grown on a defined synthetic wastewater supplemented with 0.5% tryptone. Cell-free medium from the strain harboring the MO gene demonstrated more than a 2-fold reduction in turbidity compared with controls. Additionally, no significant amount of MO was observed without the addition of the synthetic wastewater, suggesting that it served as a source of nutrients for the effective expression and translocation of MO into the medium.

Full text
Abstract:
The Smart Energy Design Assistance Center assessed the administrative, technical, and economic aspects of feasibility related to the procurement and installation of photovoltaic solar systems on IDOT-owned buildings and lands. To address administrative feasibility, we explored three main ways in which IDOT could procure solar projects: power purchase agreement (PPA), direct purchase, and land lease development. Of the three methods, PPA and direct purchase are most applicable for IDOT. While solar development is not free of obstacles for IDOT, it is administratively feasible, and regulatory hurdles can be adequately met given suitable planning and implementation. To evaluate IDOT assets for solar feasibility, more than 1,000 IDOT sites were screened and narrowed using spatial analytic tools. A stakeholder feedback process was used to select five case study sites that allowed for a range of solar development types, from large utility-scale projects to small rooftop systems. To evaluate financial feasibility, discussions with developers and datapoints from the literature were used to create financial models. A large solar project request by IDOT can be expected to generate considerable attention from developers and potentially attractive PPA pricing that would generate immediate cash flow savings for IDOT. Procurement partnerships with other state agencies will create opportunities for even larger projects with better pricing. However, in the near term, it may be difficult for IDOT to identify small rooftop or other small on-site solar projects that are financially feasible. This project identified two especially promising solar sites so that IDOT can evaluate other solar site development opportunities in the future. This project also developed a web-based decision-support tool so IDOT can identify potential sites and develop preliminary indications of feasibility. We recommend that IDOT begin the process of developing at least one of their large sites to support solar electric power generation.

Abstract:
Objectives. To assess benefits and harms of nonpharmacological and pharmacological interventions for breathlessness in adults with advanced cancer. Data sources. We searched PubMed®, Embase®, CINAHL®, ISI Web of Science, and the Cochrane Central Register of Controlled Trials through early May 2020. Review methods. We included randomized controlled trials (RCTs) and observational studies with a comparison group evaluating benefits and/or harms, and cohort studies reporting harms. Two reviewers independently screened search results, serially abstracted data, assessed risk of bias, and graded strength of evidence (SOE) for key outcomes: breathlessness, anxiety, health-related quality of life, and exercise capacity. We performed meta-analyses when possible and calculated standardized mean differences (SMDs). Results. We included 48 RCTs and 2 retrospective cohort studies (4,029 patients). The most commonly reported cancer types were lung cancer and mesothelioma. The baseline level of breathlessness varied in severity. Several nonpharmacological interventions were effective for breathlessness, including fans (SMD -2.09 [95% confidence interval (CI) -3.81 to -0.37]) (SOE: moderate), bilevel ventilation (estimated slope difference -0.58 [95% CI -0.92 to -0.23]), acupressure/reflexology, and multicomponent nonpharmacological interventions (behavioral/psychoeducational combined with activity/rehabilitation and integrative medicine). For pharmacological interventions, opioids were not more effective than placebo (SOE: moderate) for improving breathlessness (SMD -0.14 [95% CI -0.47 to 0.18]) or exercise capacity (SOE: moderate); most studies were of exertional breathlessness. Different doses or routes of administration of opioids did not differ in effectiveness for breathlessness (SOE: low). Anxiolytics were not more effective than placebo for breathlessness (SOE: low). Evidence for other pharmacological interventions was limited. Opioids, bilevel ventilation, and activity/rehabilitation interventions had some harms compared to usual care. Conclusions. Some nonpharmacological interventions, including fans, acupressure/reflexology, multicomponent interventions, and bilevel ventilation, were effective for breathlessness in advanced cancer. Evidence did not support opioids or other pharmacological interventions within the limits of the identified studies. More research is needed on when the benefits of opioids may exceed harms for broader, longer term outcomes related to breathlessness in this population.
