A mobile app for delirium screening

Abstract Objective The objective of this study is to describe the algorithm and technical implementation of a mobile app that uses adaptive testing to assess an efficient mobile app for the diagnosis of delirium. Materials and Methods The app was used as part of a NIH-funded project to assess the feasibility, effectiveness, administration time, and costs of the 2-step delirium identification protocol when performed by physicians and nurses, and certified nursing assistants (CNA). The cohort included 535 hospitalized patients aged 79.7 (SD = 6.6) years enrolled at 2 different sites. Each patient was assessed on 2 consecutive days by the research associate who performed the reference delirium assessment. Thereafter, physicians, nurses, and CNAs performed adaptive delirium assessments using the app. Qualitative data to assess the experience of administering the 2-step protocol, and the app usability were also collected and analyzed from 50 physicians, 189 nurses, and 83 CNAs. We used extensible hypertext markup language (XHTML) and JavaScript to develop the app for the iOS–based iPad. The App was linked to Research Electronic Data Capture (REDCap), a relational database system, via a REDCap application programming interface (API) that sent and received data from/to the app. The data from REDCap were sent to the Statistical Analysis System for statistical analysis. Results The app graphical interface was successfully implemented by XHTML and JavaScript. The API facilitated the instant updating and retrieval of delirium status data between REDCap and the app. Clinicians performed 881 delirium assessments using the app for 535 patients. The transmission of data between the app and the REDCap system showed no errors. Qualitative data indicated that the users were enthusiastic about using the app with no negative comments, 82% positive comments, and 18% suggestions of improvement. Delirium administration time for the 2-step protocol showed similar total time between nurses and physicians (103.9 vs 106.5 seconds). Weekly enrollment reports of the app data were generated for study tracking purposes, and the data are being used for statistical analyses for publications. Discussion The app developed using iOS could be easily converted to other operating systems such as Android and could be linked to other relational databases beside REDCap, such as electronic health records to facilitate better data retrieval and updating of patient’s delirium status. Conclusion Our app operationalizes an adaptive 2-step delirium screening protocol. Its algorithm and cross-plat formed code of XHTML and JavaScript can be easily exported to other operating systems and hardware platforms, thus enabling wider use of the efficient delirium screening protocol that we have developed. The app is currently implemented as a research tool, but with adaptation could be implemented in the clinical setting to facilitate widespread delirium screening in hospitalized older adults.
Direct numerical simulations of incompressible Rayleigh–Taylor instabilities at low and medium Atwood numbers

Direct numerical simulations of two-dimensional (2D) and three-dimensional (3D), single-mode and multi-mode, incompressible immiscible Rayleigh–Taylor (RT) instabilities are performed using a phase-field approach and high-order finite-difference schemes. Various combinations of Atwood number, Reynolds number, surface tension, and initial perturbation amplitude are investigated. It is found that at high Reynolds numbers, the surface tension, if significant, could prevent the formation of Kelvin–Helmholtz type instabilities within the bubble region. A relationship is proposed for the vertical distance of the bubble and spike vs the Atwood number. The spike and bubble reaccelerate after reaching a temporary plateau due to the reduction of the friction drag as a result of the formation of the spike vortices and also the formation of a momentum jet traveling upward within the bubble region. The interface for a 3D single-mode instability grows exponentially; however, a higher Reynolds number and/or a lower Atwood number could result in a noticeably larger surface area after the initial growth. It is also shown that a 3D multi-mode RT instability initially displays an exponential interface growth rate similar to single-mode RT instabilities. Due to the collapse and merging of individual single-mode instabilities, the interface area for a multi-mode RT instability is strongly dependent to the mesh resolution after the exponential growth rate. However, the ratio of kinetic energy over released potential energy exhibits an almost steady state after the initial exponential growth, with values around 0.4, independently of the mesh resolution.
Interaction of Titanium Dioxide with Formaldehyde in the Presence of Quartz Sand under Static and Dynamic Conditions

Formaldehyde (FA) is an extremely active compound that is widely used in numerous applications. Given that FA is a known carcinogen, it is essential to remove it from the environment. Titanium dioxide (TiO2), due to its special physicochemical properties, is a promising adsorbent for the removal of specific organic compounds from aqueous solutions. In this study, the interaction of TiO2 with FA in the presence and absence of quartz sand, the most common mineral on the Earth’s surface, was investigated under static and dynamic (batch) conditions, at 25 °C. The experimental data suggested that the sorption of FA onto TiO2 can be described adequately by a pseudo-second order kinetic model, indicating that the main sorption mechanism was chemisorption. It was observed that the combination of TiO2 and quartz sand could1 lead up to effective removal of FA from aqueous samples.
Short term memory in aphasia: effects of modality and relationship with Western Aphasia Battery-R performance

ABSTRACT Background Producing and comprehending language requires maintenance of linguistic units in short term memory (STM). While there is evidence of verbal STM impairments in persons with aphasia (PWA), there are unresolved questions about other aspects of STM in aphasia, particularly the role of input and output modalities on STM performance. This includes the extent to which visual STM abilities are impaired in PWA and if the modality of eliciting responses (verbal versus pointing) influences STM performance. A better understanding of the relationship between STM performance and clinical language assessments of PWA will inform test interpretation. Aims This study investigated three questions about short term memory (STM) performance in post-stroke aphasia: 1) whether visual STM is impaired in PWA given that a common neural network subserves encoding-recall of both verbal and visual STM, 2) whether the response modality (verbal vs pointing) impacts STM score, 3) the relationship between STM and language performance, specifically on the Western Aphasia Battery-Revised (WAB-R). Methods & Procedures Verbal and visuo-spatial performance on a STM battery was compared between 45 PWA and a representative neurotypical sample (N=40). For PWA, individual performance across STM subtasks was examined to identify dissociations and correlated with language performance on the WAB-R. Outcomes & Results PWA scored lower than neurotypical controls on verbal but not visual STM tasks. At the individual level, about one-half of PWA were impaired on the three verbal STM tasks, and one-third had dissociations among the three verbal STM tasks. There was no effect of response modality (verbal versus pointing) on verbal STM performance. There was a strong association between verbal STM and individual subtests of the WAB-R. In general, the relative phonological and semantic demands of the task (e.g. repetition) influenced the association strength with digit recall versus picture recall scores. Conclusions Verbal STM deficits are: 1) more prevalent than visual-spatial STM deficits in PWA, 2) strongly associated with WAB-R performance in a pattern that is consistent with the phonological and semantic demands of the tasks. The clinical implications of this study are that it is crucial to assess STM performance in PWA and examine its potential impact on language assessments. Further, a verbal or pointing response modality can be used for STM measurement without negatively impacting the score (unless there are clear motoric contra-indications). This study provides performance data for a set of aphasia-friendly STM tasks that can serve as future reference.
Kinetic coefficients for the domestic wastewater treatment using hybrid activated sludge process

AbstractIn this study, the performance of a novel configuration of the hybrid growth bioreactor in pilot-plant scale (containing of anoxic, aerobic and sedimentation sections) was investigated for Isfahan municipal wastewater treatment plants. The bioreactor performance was evaluated after primary sedimentation tanks under the inlet COD concentration of 0.27 ± 0.02 g/L, at different suspended biomass concentrations of about 3, 4, and 5 as g/L and different total hydraulic retention times 4, 8, and 12 h. An industrial moving bed packing with protected specific surface area of 350 m2/m3 was used in the bioreactor with a 30% of filling ratio. The modified Stover–Kincannon and Grau models are applied to predict the bio kinetic coefficients of COD removal. According to the results obtained, the substrate removal rate constant (ks) for Grau model was in the range of 8.23–10.96 (1/d), and the saturation constant (KB) value and the maximum total substrate utilization rate (Umax) for modified Stover–Kincannon were.
Factores que influyen en la deserción de la carrera de Administración de Empresas del Centro Universitario de Quiché -CUSACQ –

La deserción es un fenómeno presente en todos los niveles educativos y se refiere directamente a los estudiantes que toman la decisión de retirarse definitivamente de un programa de estudios o al abandono de los mismos, sin alcanzar su graduación en el tiempo programado. La investigación se llevó a cabo para describir los factores que causan la deserción universitaria de los estudiantes de las cohortes 2014-2018 de la carrera de Administración de Empresas del Centro Universitario de Quiché, con sede en Santa Cruz del Quiché. La metodología de la investigación se basó en el método descriptivo, con el fin de identificar los factores que influyen en la deserción, juntamente con el enfoque mixto que coadyuvan para la triangulación de resultados luego de tabular los datos obtenidos en los instrumentos utilizados. Se tomo en cuenta los factores; personales, académicos, institucionales y socioeconómicos. La situación de la deserción es multifactorial sin embargo en este estudio tuvo mayor frecuencia, por un lado, los académicos; el bajo rendimiento de los estudiantes, la transición de nivel educativo, la preparación en ciertas áreas específicamente en matemáticas y por otro lado en los económicos; la falta de oportunidades de trabajo, los bajos ingresos, la coincidencia entre horarios de trabajo y clase que no permiten poder continuar la preparación académica ya que prefieren trabajar para satisfacer las necesidades básicas y optan por retirarse. La mayor deserción se da en los primeros años de estudio, específicamente en el segundo bimestre.
The Congo deep-sea fan: Mineralogical, REE, and Nd-isotope variability in quartzose passive-margin sand

The Congo deep-sea fan, the largest on Earth fed entirely with anorogenic detritus, is characterized by quartzose to pure quartzose sand, reflecting multiple recycling coupled with extreme chemical weathering in cratonic equatorial Africa. The very youthful lower course of the Congo River connects directly to a steep canyon, where detritus including quartz grains up to a few millimeters in diameter is funneled towards Atlantic Ocean floors and deposited at abyssal depths more than a thousand kilometers away from shore. This article illustrates for the first time in detail the mineralogical and geochemical signatures of Congo Fan sands and discusses the factors controlling their intersample and intrasample variability as a key to understand how sediment is generated, recycled, and finally transferred to the deep sea. Compositional variability is largely grain-size-dependent. Combined petrographic and Raman spectroscopy analyses demonstrate that quartz increases in coarser samples and size classes, whereas feldspars are concentrated in finer sizes, plagioclase relative to K-feldspar and orthoclase relative to microcline, defining an order of mechanical and chemical durability among detrital tectosilicates. Because of overwhelming quartz abundance and very low heavy-mineral concentration, quartz contributes significantly to the REE budget and up to 40–50% of Nd in coarser samples, characterized by εNd values as low as –21. The strong grain-size-dependent variability of εNd suggests that quartz carries a markedly more negative εNd signature than monazite and other detrital components. This is chiefly ascribed to the durability of quartz grains, able to survive repeated cycles of weathering and diagenesis through Proterozoic and Phanerozoic time better than all other minerals. Neodymium model ages are influenced less by grain size and quartz abundance but more by the Sm/Nd ratio of different detrital components, and samples hydrodynamically enriched in LREE-rich minerals display TNd,CHUR and TNd,DM ages 1.2–1.4 Ga younger than samples enriched in HREE minerals. Not all detritus in the Congo Fan is supplied transversally by the Congo River. Forward-mixing calculations based on mineralogical data indicate that sand entrained northward by longshore currents mixes progressively with Congo River sand along the northernmost Angola coast, penetrates in the Soyo estuary, and is eventually captured in the canyon and transferred to the deep-sea fan, where it is estimated to represents 7 ± 2% of turbidite deposits.
Industrial use of whey in the production of a yogurt-type fermented milk drink with Aloe vera L. (Asphodelaceae) crystals and Passiflora ligularis Juss. (Passifloraceae)

Currently, the food industry searches for innovation and the use of natural and more economical resources. With this in mind, the industrial application of whey was used to elaborate a yogurt-type fermented milk drink with Aloe vera L. crystals (Asphodelaceae) and Passiflora ligularis Juss. (Passifloraceae). For this purpose, A. vera crystals and granadilla or passionfruit pulp, were extracted and added to the four formulations established. Physicochemical, bromatological, microbiological, and sensory analyses (hedonic test) were carried out. The formulations with the highest content of A. vera (F4) and granadilla (F2) showed the best results in bromatological, microbiological, and sensory properties. The A. vera crystals and the granadilla pulp are of great industrial value due to the improvement that their addition gave to the physicochemical, bromatological, microbiological, and sensory properties of the yogurt-type fermented milk drink.
Increasing Occurrence of Atlantic Bluefin Tuna on Atlantic Herring Spawning Grounds: A Signal of Escalating Pelagic Predator–Prey Interaction?

Predation can be a signi ﬁ cant source of natural mortality for small pelagic ﬁ sh species, rivaling or exceeding ﬁ shery removals. Failure to account for changes in natural mortality can introduce uncertainty in the assessment and management of these stocks. In this study, a 10-year span of hydroacoustic data was used to detect Blue ﬁ n Tuna Thunnus thynnus on two major fall spawning grounds of Atlantic Herring Clupea harengus , an economically and eco- logically valuable forage ﬁ sh species in the southern Gulf of St. Lawrence (sGSL). Average Blue ﬁ n Tuna detections increased 22-fold from 2002 to 2012 on both spawning grounds independently of Atlantic Herring density or aggrega- tion size. This increase is directionally consistent but larger than changes in other Blue ﬁ n Tuna population indices. Preliminary estimates of annual Atlantic Herring consumption doubled across the time series, reaching values of 4,300 – 20,000 metric tons in recent years. This would suggest that Blue ﬁ n Tuna are among the most important consumers of Atlantic Herring in the sGSL. These ﬁ ndings are key for an ecosystem-based approach to the assessment and management of both Atlantic Herring and Blue ﬁ n Tuna in the sGSL.
Effects of breeder age and short-term temperature stimulation during incubation on performance, organ weight, and carcass yield in male and female broilers

Birds develop thermoregulatory control during the last days of incubation. Different temperature conditioning programs have been proposed to prepare broiler chicks for post-hatch life. This study aimed to investigate the effects of short-term temperature (STT) stimulation and breeder age on hatching performance, embryo development, yolk absorption, and post-hatch performance of male and female broilers. A 2 × 2 factorial completely randomized design was used, with two breeder ages (30 and 60 wk), two temperature incubation programs (control and STT), and 2,520 eggs per treatment. Eggs were distributed in two large-scale commercial incubators with a capacity of 120,960 eggs. The control group was subjected to a standard single-stage incubation program (37.2-37.4 °C), whereas the STT group was subjected to a temperature increment of 1 °C for 4 h on embryonic days 16, 17, 18, and 19. Embryos were analyzed at 16 and 19 days of incubation, and chicks at hatch. At 19 days of incubation, STT conditioning resulted in lower yolk sac weight in embryos from 60-wk-old breeders and higher relative weight of the gastrointestinal tract in embryos from 30-wk-old breeders. At hatch, males had lower residual yolk weight, females had greater length, and chicks from 60-wk-old breeders subjected to STT had higher body weight and relative weight of the gastrointestinal tract. Eggs from 30-wk-old breeders showed higher fertility and hatchability and lower infertility, mortality, and second-grade chick percentages. Regarding performance, it was found that males had higher body weight from 7 to 42 days of age and higher whole leg yields. Females, on the other hand, had higher fat yields. Breeder age and sex influenced gastrointestinal tract development, carcass yield, and performance. A 1 °C increase in incubation temperature for 4 h from days 16 to 19 of incubation affected yolk absorption and digestive tract development in chicks from 60-wk-old breeders without, however, influencing performance results.
Effects of Dilution on Laminar Burning Velocity of Premixed Methane/Air Flames

Effects of dilution on premixed methane/air combustion are investigated through experiments and numerical simulations on laminar burning velocities. Experiments are carried out at atmospheric pressure and 393 K; computed results are obtained using the GRI mechanism and the Premix code of the Chemkin package. Laminar burning velocities are determined for several diluents (nitrogen, carbon dioxide, vapor water, a mixture of the three previous gases representative of exhaust gases, helium, and argon) and for different dilution percentages. The equivalence ratio is kept constant equal to stoichiometric. Excellent agreements between experimental data and computed results are obtained. Because heat capacity seems to possess the predominant effect on the laminar flame, an explicit correlation between the heat capacity of the diluent and the laminar burning velocity is proposed.
CEO narcissism, top management team transactive memory systems, and firm performance: an upper echelons perspective on CEO admiration and rivalry narcissism

ABSTRACT A growing body of conceptual and empirical research has drawn on transactive memory systems (TMS) theory to understand the functioning of a wide range of teams, including top management teams (TMTs). At the same time, there has been increasing interest in how personality factors, and in particular chief executive officer (CEO) narcissism, shape corporate decision-making, and behaviour in TMTs. However, these streams of research have developed independently from one another. Leveraging a sample of 64 firms, we integrate TMS theory and upper echelons theory to explain how the performance consequences of TMTs are shaped by two competing dimensions of CEO narcissism: admiration-based narcissism and rivalry-based narcissism. CEO narcissism is an important area of research because of the strategic implications of the impact that this personality trait can have on the functioning of the TMT. We find that TMT TMS has a positive influence on firm performance at higher levels of admiration-based narcissism, but not rivalry-based narcissism. With this focus, we provide further substantiation of the firm-performance implications of TMS, and the critical role played by a dimensional focus on CEO narcissism in the TMS context.

Foreign Direct Investment and Financial Constraints: Firm-Level Evidence from Cambodia, Lao PDR, and Myanmar

Financial constraints have been a significant obstacle to firms operating in developing countries. Prior studies show that foreign direct investment (FDI) helps to ease credit constraints for domestic firms. However, they only account for horizontal FDI spillovers. This paper therefore investigates both horizontal and vertical FDI spillovers using firm-level data from Cambodia, Lao PDR, and Myanmar (CLM). The key findings of this paper are threefold. First, FDI inflows lessen the financial constraints faced by local firms through partnership or joint venture. Second, an increasing share of FDI in horizontally and vertically related industries raises higher credit constraints for domestic firms. Third, the crowding-out effect of FDI is not uniform across domestic firms of different sizes. Therefore, policymakers should be aware of these possible negative spillovers and formulate policy to maintain FDI inflows while also ensuring the growth and survival of domestic firms.
