Authors: Zuccarello Pietro , Conti Gea Oliveri , Fiore Maria , Elfio M.G. , Saitta Sonia , Copat Chiara , Cristaldi Antonio , Ferrante Margherita 
Published: January 2021

Background:
Sicilian surface basins are among the most important water supply resources available on the island. They are often affected by harmful cyanobacteria blooms as Planktothrix rubescens and Microcystis aeruginosa. Since dialysates are produced using network water, they could contain cyanotoxins. No study has been conducted yet to evaluate the removal efficiency of osmotic systems for cyanotoxins in abnormal conditions at room temperatures of about 40°C. The aim of this study was to monitor the presence of microcystins in Sicilian dialysis center, network waters and, finally, dialysates produced from these waters in an Agrigento dialysis unit where environmental conditions are favorable for algal bloom.

Methods:
This clinic normally receives surface water from artificial basins, where several times, traces of cyanobacteria have been detected. Moreover, dialysates and underground supply waters of a clinic in Catania were also sampled as control. Samplings were performed in summer 2018, when room temperatures were above 38 °C. A total of 40 samples were analyzed by ELISA assay.

Results:
Results of our monitoring highlighted concentrations of MCs in waters of several basins among LOD - 155 ng/L, lower than WHO reference value for drinking waters (1,0 µg/L), that decrease up to undetectable levels whereas no MC contamination was detected both in supply waters and dialysates.

Conclusion:
Although our first set of data outcomes seem to be quite comforting, an improvement of law and a complete census of the water supplies of dialysate centers would be ideal.
The Effect of Fiberoptic Bronchoscopy-guided Technique for Placement of a Left-sided Double-lumen Tube on the Intubation Performance Compared with the Conventional Method Using a Macintosh Laryngoscope
Authors: Lim Jung A. , Kim In-Young , Byun Sung Hye 
Published: January 2021

Background:
The accurate placement of the double-lumen endotracheal tube is imperative for effective one-lung ventilation in thoracic surgery. Malpositioning and repositioning of a misplaced tube may cause excessive trauma.

Objective:
We hypothesized that the fiberoptic bronchoscope-guided method for double-lumen endotracheal tube placement would reduce the incidence of malpositioning as compared to the conventional method using the Macintosh laryngoscope.

Methods:
Fifty patients scheduled to undergo elective thoracic surgery were recruited and randomly assigned to the fiberoptic bronchoscope-guided [n=25; Group F] and conventional [n=25; Group C] method groups, according to the method of double-lumen endotracheal tube placement. The primary outcome was the incidence of double-lumen endotracheal tube malpositioning observed under the fiberoptic bronchoscope after initial placement. Secondary outcomes included the times for placement, confirmation, and total procedure of double-lumen endotracheal tube intubation.

Results:
The incidence of malpositioning after initial double-lumen endotracheal tube placement was significantly lower in Group F than in Group C (20.0% vs 68.0%). In addition, the time for placement was significantly higher in Group F than in Group C, and that for confirmation was significantly lower in Group F than in Group C.

Conclusion:
The fiberoptic bronchoscope-guided method for double-lumen endotracheal tube placement can reduce the incidence of malpositioning after initial placement and expedite the intubation process with a double-lumen endotracheal tube in thoracic surgery.

Published: January 2021

Background
Wearable technology for fall alerts among older adult care recipients is one of the more frequently studied areas of technology, given the concerning consequences of falls among this population. Falls are quite prevalent in later life. While there is a growing amount of literature on older adults’ acceptance of technology, less is known about how caregivers’ attitudes toward technology can impact care recipients’ use of such technology.

Objective
The objective of our study was to examine associations between caregivers’ attitudes toward technology for caregiving and care recipients’ use of fall alert wearables.

Methods
This study examined data collected with an online survey from 626 caregivers for adults 50 years and older. Adapted from the technology acceptance model, a structural equation model tested the following prespecified hypotheses: (1) higher perceived usefulness of technologies for caregiving would predict higher perceived value of and greater interest in technologies for caregiving; (2) higher perceived value of technologies for caregiving would predict greater interest in technologies for caregiving; and (3) greater interest in technologies for caregiving would predict greater use of fall alert wearables among care recipients. Additionally, we included demographic factors (eg, caregivers’ and care recipients’ ages) and caregiving context (eg, caregiver type and caregiving situation) as important predictors of care recipients’ use of fall alert wearables.

Results
Of 626 total respondents, 548 (87.5%) with all valid responses were included in this study. Among care recipients, 28% used fall alert wearables. The final model had a good to fair model fit: a confirmatory factor index of 0.93, a standardized root mean square residual of 0.049, and root mean square error of approximation of 0.066. Caregivers’ perceived usefulness of technology was positively associated with their attitudes toward using technology in caregiving (b=.70, P<.001) and interest in using technology for caregiving (b=.22, P=.003). Greater perceived value of using technology in caregiving predicted greater interest in using technology for caregiving (b=.65, P<.001). Greater interest in using technology for caregiving was associated with greater likelihood of care recipients using fall alert wearables (b=.27, P<.001). The caregiver type had the strongest inverse relationship with care recipients’ use of fall alert wearables (unpaid vs paid caregiver) (b=–.33, P<.001).

Conclusions
This study underscores the importance of caregivers’ attitudes in care recipients’ technology use for falls management. Raising awareness and improving perception about technologies for caregiving may help caregivers and care recipients adopt and better utilize technologies that can promote independence and enhance safety.
Estimation of Municipal Income Distribution in Mexico
Authors: Ojeda Ramírez Mario Miguel , Gallardo Del Ángel Roberto , Cruz López Cecilia 
Published: January 2021

Purpose: To ffer an estimation of income distribution measures for municipalities in Mexico for year 2015, and also an analysis of municipal grants on income inequality.Methodological design: We constructed Gini and Atkinson indexes using microdata from the Mexican inter-census survey 2015. We use these inequality indexes along with other several features of poverty and marginality to perform cluster analysis and classify municipalities. From our cluster analysis, we classified the municipalities in four groups: low, medium-low, medium-high and high-income inequality. Afterwards, we performed weighted least squares regressions to observe the effect of fiscal variables on inequality in each group.Results: Although the objective of federal grants has been poverty instead of inequality, we offer evidence that income inequality is inversely affected by the design of federal grants. The regression analysis shows that conditional grants designed to reduce poverty might be increasing inequality, while unconditional grants may help to reduce income inequality even though this is not their policy objective.Research limitations: The main limitation might be the lack of local statistics for other years to perform a dynamic analysis.Findings: The overall effect of conditional grants on income distribution is small but still positive, showing that conditional grants do not reduce income inequality. The estimates show that the total effect is for lower income inequality, especially in those municipalities with high and very high inequality.
Las revistas científicas, la ciencia abierta y la medición entre las métricas y almétricas: un espejismo de la imagen de la ciencia versus la falsación científica
Authors: Valencia Grajales José Fernando , Valencia Grajales Andrea María , Marín Galeano Mayda Soraya 
Published: January 2021

Las revistas científicas, como mecanismo de difusión de la ciencia, han venido cambiando de rumbo al sacar la ciencia de los guetos y democratizar el conocimiento, poniendo a disposición del mundo entero sus estudios. Sin embargo, al hacerlo se exponen a una carrera mortal por el prestigio, la imagen, el impacto, la visibilidad, el cuidado de las normas éticas y la financiación que no siempre van de la mano. Para visibilizar estos retos y dificultades se procederá con una metodología histórico-crítica aunada al análisis del discurso. Para ello, primero se hará un recuento de la evolución histórica de las revistas, luego se procederá con la evidencia de las primeras métricas empleadas, después se mostrarán las nuevas formas de medición almétricas y finalmente se ensayarán unas conclusiones.
Logical Consequence Operators and Etatism
Authors: Krysztofiak Wojciech 
Published: January 2021

Abstract
In the paper, there is presented the theory of logical consequence operators indexed with taboo functions. It describes the mechanisms of logical inference in the environment of forbidden sentences. This kind of processes take place in ideological discourses within which their participants create various narrative worlds (mental worlds). A peculiar feature of ideological discourses is their association with taboo structures of deduction which penalize speech acts. The development of discourse involves, among others, transforming its deduction structure towards the proliferation of consequence operators and modifying penalty functions. The presented theory enables to define various processes of these transformations in the precise way. It may be used in analyses of conflicts between competing elm experts acting within a discourse.

In previous decade the herbal drugs have been investigated for their medicinal properties for the natural therapy. About half of the people around the world, even in the developed countries had been using the medicinal plants and natural drugs as treatment of diseases. In this regard the herbs should also be investigated for their pharmacological properties, safety concerns and efficacy too. In the present investigation, we have believed medicine and inhibiting potential effects of extract of C. auriculata was investigated for the hepatoprotective activity. This study facilitated to rediscover the new ancient medication for the treatment of liver diseases. The plant C.auriculata showed very good activity in terms of the hepatoprotective nature against the liver injury by chornic use of drugs which is due to the anti-inflammatory properties added to the antioxidant activity of the herbs. These were to prevent the CCl4 induced free radicals and damage. The formation of cellular damage and free radicals was inhibited. The data that we procured from the investigation shows that the antioxidant activity of the plant in both extracts of plant helped for the activity. It may contain large amounts of the phenols and flavonoids that showed free radial scavenging activity which might be responsible for the hepatoprotective activity also.

In our cultural context, home management is a great challenge that is confronted by almost all adolescent girls. This quantitative study was conceptualized to explore the ground realities regarding the capability of young girls to manage their homes. The population of study consisted of all young girls enrolled in degree and higher education programmes of colleges and universities. A sample of 100 young girls (18-25 years old) was selected conveniently from 4 eminent public and private sector universities in Punjab. A self developed and validated questionnaire (cronbach Alpha: .91) containing components of home management including time management, money management, team work, cleaning habit, laundry, cooking and how to plan a menu containing 28 statements on three point Likert type scale was used to collect data. Personally collected data from the subjects were analyzed on SPSS. Analysis of variance (ANOVA) was applied to calculate the mean difference among different home management skills and to see the mean difference in the expertise level of young girls in managing their homes on the basis of studying in different universities. Moreover, t-test was run to see the difference between the girls, belong to rural and urban areas. Frequency distribution of responses was calculated. Major findings revealed that young girls were not good in time management, laundry and cooking. Conclusions were drawn and recommendations to the families of girls, and universities for the inclusion of subject of Home Management in the curricula of respective department were made.
Fully Charged: Characterizing the Data Requirements of Services and Apps to Optimize the Use of Energy
Authors: Larracoechea Jorge Andrés , Ilarri Sergio , Roose Philippe 
Published: January 2021

Energy is consumed in devices in a different manner according to their available limited resources (such as battery) in an attempt to fulfill tasks imposed by the services’ processing and data demands. This has led ICT researchers to find interest in strategies for mitigating high energy consumptions when processing and transferring data. For example, efforts on delivering efficient software code that preserves energy by being architecturally efficient and conscious about resource usage have been done in the past, but we consider that other approaches could be implemented in order to further increase energy savings. We present an introduction to our future work that aims at analyzing and categorizing a wide range of situations and example applications that may have an impact on the most suitable decisions to be taken regarding the needs of the service/application and the expected energy consumption.
Questioning the algorithmic transparency of location-based platforms
Authors: Parisi Lorenza , Parente Giovanni Andrea 
Published: January 2021

In the platform society algorithms are perceived as ‘black boxes’ (Pasquale, 2015) and users have only a vague understanding of the criteria they adopt to select information. Location-based platforms algorithms influence the visibility of different points of interest (POI), thus shaping the user interaction with venues and places.

The paper adapts the Diakopoulos and Koliska model (2017) and presents a new framework for analyzing the algorithmic transparency of location-based platforms. Research questions are the following: RQ1) How location-based platforms communicate algorithmic transparency?; RQ2) Which are the most relevant dimensions they take into consideration (data, model, inference, interface)?; RQ3) How platforms communicate transparency toward different targets (i.e. consumers and suppliers)? Following Rader, Cotter and Cho (2018) we expect location-based platforms are less transparent about the data they manage and about their model they use and more transparent about the inferences. Moreover, we expect location-based platforms are more transparent toward suppliers rather than consumers.

The paper analyzes how 3 very popular location-based platforms (Google Maps, Tripadvisor and Instagram) disclose algorithmic transparency as it emerges from the analysis of ‘extant’ online data officially released (policies, guidelines, and tutorials) and from the analysis of the platforms’ mobile interface.
The analysis revealed platforms are less transparent about the data they manage and model they use, and more transparent, only toward suppliers, about the inferences they propose. Moreover, location-based platforms are more transparent toward suppliers rather than consumers; indeed, commercial interests favours the algorithmic transparency and visibility of location-based content.
Ateroesclerosis en Vilcabamba
Authors: Salvador Miguel 
Published: January 2021

Se establece en primer lugar que en algunos estudios sobre los habitantes de Vilcabamba, se ha exagerado la edad por diversas circunstancias y que para el estudio de la átero-esclerosis se ha escogido exclusivamente cuarenta y seis personas mayores de 70 años; 31 hombres y 15 mujeres, de edad debidamente comprobada, de acuerdo a lo encontrado en los estudios del Sr. Richard Mazzes y Silvia Forman, quienes han confeccionado un listado de los habitantes de Vilcabamba con la respectiva edad técnicamente establecida.
En los cuarenta y seis sujetos estudiados se ha realizado además del estudio clínico y electrocardiográfico la dosificación de lípidos sanguíneos.
Se pone en manifiesto que tanto la ecología del lugar, como los factores alimentarios a más del ejercicio físico que practican estos sujetos, son sin lugar a duda, aparte de las características genéticas, las circunstancias que influyen en el bajo índice de impregnación aterogénica, y se puntualiza que si bien la longevidad no es una característica llamativa y espectacular en los habitantes de Vilcabamba, sin embargo existen circunstancias dignas de estudiarse, que dan a los sujetos de edad avanzada la cualidad de estar muy poco afectados por átero-esclerosis, conservando a pesar de la edad, una admirable energía para el trabajo diario y la plenitud de sus facultades mentales, presiones arteriales sistólica y diatólica dentro de la normalidad y corazones indemnes de afección coronaria.
