Does the Intuition of Distinctness Result from Valid Reasoning? – Reply to Kammerer
Authors: Polcyn Karol 
Published: November 2021

AbstractAccording to an influential physicalist view, the intuition of distinctness is a cognitive illusion in the sense that it results from fallacious reasoning: we erroneously infer that the referents of phenomenal and physical concepts are different, from the fact that there is a certain difference between our uses of those concepts. (Kammerer, Review of Philosophy and Psychology 10:649–667, 2019) has recently argued, however, that it is psychologically implausible that the intuition of distinctness results from a fallacy: the reasoning process leading to this intuition is, in several psychological respects, similar to valid reasoning and dissimilar to typical fallacies, which gives us a reason to think that this process is a case of valid reasoning. I argue that there are no psychological reasons to think that the process underlying the intuition of distinctness (or at least the crucial part of this process) is a case of valid reasoning. There is, in fact, only one crucial psychological respect in which this process resembles valid reasoning, and although the two processes are similar in one crucial respect, this does not rule out that the intuition of distinctness results from a fallacy, namely, the sort of fallacious reasoning that physicalists have in mind. Furthermore, since the process underlying the intuition of distinctness resembles typical fallacies in one crucial respect, there is a reason to think that the intuition of distinctness does result from a fallacy.

AbstractEthiopia is one of the developing countries where only 52% of its population have access to safe drinking water. To determine the level of faecal contamination in drinking water, the E. coli has been found to be the most specific indicator. The purpose of this study was to determine household bacteriological drinking water quality and its associated factors in rural North Gondar Zone Ethiopia. A community-based cross-sectional study was conducted in rural parts of North Gondar Zone from April to June, 2016. Water samples from water storage at household level were taken using standardized water sampling techniques to determine the level of faecal contamination. Face-to-face interview using structured questionnaires and checklist were used to identify the associated factors. A total of 736 households participated in this study. The prevalence of positive faecal coliform in the households is found to be 72.6% (95%C.I; 69.4–75.8). In multivariate analysis; occupational status [AOR; 0.35, 95%; CI (0.16,0.77)], income [(AOR);0.45, 95%; CI (0.3, 0.68)], type of solid waste disposal habit [AOR; 0.16, 95%; CI (0.36, 0.66)], source of water [AOR; 0.42, 95%; CI (0.28, 0.65)], shortage of water [AOR; 2.8, 95%; CI (1.88, 4)] were variables identified as predictors for faecal coliform contamination of water in the household. There is high level of faecal contamination of household drinking water in North Gondar Zone. Occupational status, income, solid waste disposal habit, sources of drinking water, and shortage of water were predictor for presence of faecal coliform contamination in household drinking water.

AbstractThe natural resources, especially water in the Densu river basin, play significant roles in the socio-economic development of Ghana. The purpose of this study was to analyse the water quality of the Densu river using water quality index (WQI) and multivariate techniques. In this study, physico-chemical and bacteriological parameters were measured from surface water samples taken from eight (8) sampling stations in the study area. water quality index and multivariate techniques such as hierarchical cluster analysis and principal component analysis were utilized in the analysis of surface water quality data. The results indicated that the average WQI of the Densu river for the two sampling periods was sixty-one (61) which is classified as Medium, based on the Solway WQI index. The pH levels of all the samples were within allowable limits of World Health Organization (WHO) guidelines. All the sampling stations for the two seasonal periods had bacteriological parameters higher than WHO guidelines, making the samples unsuitable for most domestic uses. The study revealed that six (6) principal components accounted for about 97% of the total variance of dataset and three (3) spatial clusters were classified. This research has provided the basis for applying both WQI and multivariate techniques in analysing and classifying water quality in a river basin.

AbstractTotal natural and groundwater resources play the most crucial role in developing ecological, biological and socioeconomic doings. Various parameters like land use, geology, elevation, slope, lineament, lineament density, drainage density and geomorphology affect the groundwater development of recharge and its accessibility. In this research, geographical information system (GIS), remote sensing, weighted overlay analysis and analytical hierarchy process (AHP) methods have been used for groundwater prospects mapping, and identifying suitable solutions site for soil and water conservation structures. To calculate the weights were assigned to every layers component in the determination of affecting factors. The weighted overlay analysis (WOA) tool is applied to give the sub-parameter ratings based on the scientific literature. The final map of potential groundwater zone map has prepared using Arc GIS 10.1 software and AHP methods. About 49.71% of the areas fall under the 'good potential zone, 41.05% falls under the 'moderate potential zone', and 9.22% falls under the 'poor zone by using AHP technique. Groundwater potential zone map is depend on the weighted overlay analysis and analytical hierarchy process (AHP) methods. The highest GWP is located in the lower part of the basin due to the best surface runoff gathering, infiltration situations and subsurface storage volume. The present study procedure, methods and outcomes can be valuable to estimate the suitable groundwater zones parallel to improve the dry land area in the semi-arid and arid regions of India.
Endocrine disruptors in boiled drinking water carried in plastic containers: a pilot study in Thrissur, Kerala, India
Authors: Geetha T. 
Published: November 2021

AbstractBoiled drinking water is carried by students to schools and colleges in plastic containers. However, the risk associated with drinking water stored in plastic containers is very real especially the question of leachates finding their way into the water stored in these containers. In this pilot study, we identified the most common plastic container used by students to carry water and the factors that govern their choice. Polyethylene terephthalate (PET) was identified as the most favored plastic used to carry water. PET bottles were then subject to treatments that mimic conditions representative of normal consumer usage. The water sample collected was tested for the presence of phthalates, antimony & titanium, and their content estimated by gas chromatography and atomic absorption spectra. Although phthalates and antimony leach into water from PET bottles their concentration was not high enough to pose a threat to human life. However, the trend of increasing antimony concentration with temperature and time is a cause of concern because of its role as endocrine disruptors. Prolonged and repeated use of PET bottles to carry water, especially warm water may lead to health problems in the community.

Published: November 2021

AbstractIn this study, a wastewater treatment program was developed and optimized for the treatment of sewage wastewater. Central composite face design (CCFD) and response surface methodology (RSM) were utilized to develop the experimental design and to establish the relationship between the independent variables (coagulant and flocculant dosage) and responses (turbidity and total dissolved solids removal). Statistical analysis showed that the developed response models were accurate. Optimal removal efficiencies of 93.3% and 23.2% for turbidity and TDS, respectively, were obtained under the optimal conditions for coagulant (120.9 ppm of U6750) and flocculant (125 ppm of Floc887) dosage. This showed that the developed treatment using the coagulant, U6750 and flocculant, Floc887 improved the physical characteristics of the wastewater.

Published: November 2021

AbstractGroundwater quality appraisal is one of the most crucial tasks to ensure safe drinking water sources. Concurrently, a water quality index (WQI) requires some water quality parameters. Conventionally, WQI computation consumes time and is often found with various errors during subindex calculation. To this end, 8 artificial intelligence algorithms, e.g., multilinear regression (MLR), random forest (RF), M5P tree (M5P), random subspace (RSS), additive regression (AR), artificial neural network (ANN), support vector regression (SVR), and locally weighted linear regression (LWLR), were employed to generate WQI prediction in Illizi region, southeast Algeria. Using the best subset regression, 12 different input combinations were developed and the strategy of work was based on two scenarios. The first scenario aims to reduce the time consumption in WQI computation, where all parameters were used as inputs. The second scenario intends to show the water quality variation in the critical cases when the necessary analyses are unavailable, whereas all inputs were reduced based on sensitivity analysis. The models were appraised using several statistical metrics including correlation coefficient (R), mean absolute error (MAE), root mean square error (RMSE), relative absolute error (RAE), and root relative square error (RRSE). The results reveal that TDS and TH are the key drivers influencing WQI in the study area. The comparison of performance evaluation metric shows that the MLR model has the higher accuracy compared to other models in the first scenario in terms of 1, 1.4572*10–08, 2.1418*10–08, 1.2573*10–10%, and 3.1708*10–08% for R, MAE, RMSE, RAE, and RRSE, respectively. The second scenario was executed with less error rate by using the RF model with 0.9984, 1.9942, 3.2488, 4.693, and 5.9642 for R, MAE, RMSE, RAE, and RRSE, respectively. The outcomes of this paper would be of interest to water planners in terms of WQI for improving sustainable management plans of groundwater resources.

Published: November 2021

AbstractUnderstanding the behavior of the borehole temperature recovery process, which influences drilling operations, requires an adequate estimation of fluid temperature. The presence of salt in a saline formation changes the composition of the annular fluid and has a significant impact on the fluid temperature distribution during drilling operations. As a result, while drilling a saline formation, it is vital to examine the key parameter that determines an accurate estimate of fluid temperature. Using python software and statistical quantitative methods, this study proposes a simplified user-friendly computational system that analyzes the drilling fluid systems performance evaluation and selection optimization.The fluid temperature distribution of X Field in China was analyzed using Shan mathematical model as a base model. When compared to MWD data from the field, the model predicted the temperature distribution of the field with less than 10% error. An adjustment factor was introduced to the base model to accommodate for changes in annular fluid composition while drilling a saline formation. The findings show that salt concentration has an impact on fluid temperature distribution during drilling. The fluid temperature at the wellbore condition changes by at least 7% with both high and low adjustment factors. Because the salt in the formation inflow dissolves in the drilling fluid near the annulus, the rheology of the fluid combination changes.
Genetic and environmental contributions to variations on appetitive traits at 10 years of age: a twin study within the Generation XXI birth cohort
Authors: Warkentin Sarah , Severo Milton , Fildes Alison , Oliveira Andreia 
Published: November 2021

Abstract
Purpose
Given the variability in adiposity despite ubiquitous exposure to obesogenic food environments, it has been suggested that individuals respond in divergent ways to the environment they live in. The food environment becomes more ‘permissive’ as children age; therefore, genetic predisposition for a more avid appetite can be better expressed, influencing dietary quality, energy intake and weight gain. Our aim was to explore the genetic and environmental contribution of variations on appetitive traits in a sample of 10-year-old Portuguese children.

Methods
Participants were twins enrolled in the Generation XXI birth cohort (n = 86 pairs). Parents reported twin’s zygosity and child appetitive traits at 10 years of age through the Children’s Eating Behavior Questionnaire. Intra-class correlations (ICCs) for all appetitive traits were calculated for monozygotic and dizygotic twins separately to examine patterns of resemblance, and structural equation modeling was conducted aiming to estimate the genetic (A), shared (C) and non-shared (E) environmental variances.

Results
Moderate to strong heritability were found for child appetitive traits, with higher ICCs among monozygotic twin pairs. For all appetitive traits, with the exception of emotional undereating, genetic and non-shared environmental effects contributed to appetite variability. For emotional undereating, environmental effects seem to be more important than genetic effects (C: 0.81; 95% CI 0.71; 0.88 and E: 0.19; 95% CI 0.12; 0.29).

Conclusion
There was a significant genetic contribution, followed by non-shared environmental contribution, towards variation in appetitive traits in school-age children. Variation in emotional undereating was primarily explained by shared and non-shared environmental factors.

Level of evidence
Evidence obtained from well-designed cohort or case–control analytic studies.
The Impact on Ambulance Mobilisations of an Increasing Age Profile of Telecare Service Users Receiving Advanced Proactive, Personalised Telecare in Spain—a Longitudinal Study 2014–2018

Published: November 2021

AbstractAdvanced proactive personalised telecare services in Spain have helped service users to live independently in their own homes for longer. Concern was however noted regarding potential impacts on ambulance mobilisations as time in the service, and mean age at cessation, increased. The purpose of this study was to investigate these impacts.A longitudinal study of a telecare service user population in Spain (n = 202.1 k to 247.9 k) was undertaken using anonymised operational data collected in the delivery of proactive and personalised telecare services over the period 2014–2018.For the studied population, ambulance mobilisation on a per-person/per-annum (pp/pa) basis reduced despite the increasing age profile at cessation and with the characteristics of the population at registration remaining otherwise similar over the period. The study identified the positive correlation coefficient between ambulance mobilisations and service user’s dependency levels, and marginal negative correlation in older age bands.In conclusion, the increasing age at cessation has not correlated with an increased proportion of higher dependency service users. Indeed, the share of those over 85 years in the high dependency level decreased. This indicates that the changes in the telecare service which appear to have contributed to increased time living independently may also have helped ensure those continuing to live independently remain in lower risk bands.
Exploring Inequalities in the Social, Spatial and Material Practices of Teaching and Learning in Pandemic Times
Authors: Boys Jos 
Published: November 2021

AbstractThis article conceptualises higher education as a complex and dynamic set of entangled social, spatial and material practices — enacted, adapted and contested across spaces and technologies as these interact with diverse learners, teachers, curricula and contexts. Using modes of enquiry that start from this inherent complexity and intersecting these with contemporary disability and education studies, I ask how some of the normative social and spatial practices of higher education are being surfaced by the pandemic. Rather than framing Covid-19 as a massive shift from ‘normal’ (face-to-face) to ‘abnormal’ (virtual) delivery modes, I propose that its impact both continues and alters assumptions about what constitutes ‘proper’ university education, and both perpetuates and disrupts what is ‘noticed’, valued and supported in conventional teaching and learning processes. To do this, I will focus on two themes in current HE practices in the UK, as examples of what such an approach can open-up to view. This starts from the already existing tensions, complexities and contradictions as to what should constitute appropriate teacher and student behaviours and settings, and how this ‘normality’ is often being perceived as being lost because of the pandemic. By engaging with existing literature about longer-term patterns of inequalities in access and inclusion across physical and virtual HE learning environments, I hope to show some underlying problems in how student competency is being evidenced in virtual as compared to physical space and some ways the pandemic has exposed the unevenness of diverse student and staff relationships to space, time and technologies and the differential impacts on their educational experiences.
Does glacial retreat impact benthic chironomid communities? A case study from Rocky Mountain National Park, Colorado
Authors: Jennings Danielle R. Haskett 
Published: November 2021

AbstractThe aim of this study was to determine which environmental variables are responsible for modern benthic chironomid distributions in a glacial setting. The chironomid communities from nine alpine lakes were assessed, and forty-three individual taxa were extracted and identified. Surface water temperature and nitrate were strongly and negatively correlated (−0.82, p = 0.007), suggesting that glacial meltwater (the driver that explains both surface water temperature (SWT) (°C) and nitrate (NO3 + NO2-N)) is the environmental variable that explains the most variance (15%). On average, lakes receiving glacial meltwater were 2.62 °C colder and contained 66% more NO3 + NO2-N than lakes only receiving meltwater from snow. The presence of taxa from the tribe Diamesinae indicates very cold input from running water, and these taxa may be used as a qualitative indicator species for the existence of glacial meltwater within a lake catchment. Heterotrissocladius, Diamesa spp., and Pseudodiamesa were present in the coldest lakes. Chironomus, Diplocladius, and Protanypus were assemblages found in cold lakes affiliated with the littoral zone or alpine streams. The modern benthic chironomid communities collected from the alpine of subalpine lakes of Rocky Mountain National Park, Colorado, represent a range of climatic and trophic influences and capture the transition from cold oligotrophic lakes to warmer and eutrophic conditions.

AbstractThe present study focuses on the use of feldspars from Batie granites (West-Cameroon) as a fluxing agent in ceramic applications, in order to reduce the energy cost of brick manufacture. Three alluvial clays were collected in the field using an auger and the feldspar sample was collected by hammering. Mineralogical, physical and geochemical analysis of alluvial clays samples were carried out, as well as the microscopy analysis of feldspar. The specimen of fired bricks was formulated with different proportions of feldspar (0%, 10%, 15%, 20%, and 25%) and calcined respectively at 750 °C, 850 °C, 950 °C and 1050 °C in an electric furnace. The physical analysis of the clay material showed a well graded granulometry composed of 3% gravel, 10% coarse sand, 23% fine sand, 13% silt and 51% clay. Thin section microscopic analysis revealed essentially perthites. The mineralogical analysis obtained by XRD on total powder shows that the alluvial clays are composed essentially of: 55.8% of total clays; 19.2% quartz; 14.2% goethite; 8.5% K feldspar; 1.2% anatase; 0.7% hematite and 0.4% gibbsite. Geochemical analysis shows that clay material consists of: SiO2, Al2O3, Fe2O3, TiO2, P2O5, MgO, CaO and K2O. The ceramic tests carried out on these bricks showed that their colors were red for all the formulations and temperatures tested. The sound of the bricks is metallic for the formulations of 20 and 25% of feldspar as from 850 °C. The flexural strength (greater than 3 MPa) and compressive strength (10–20 MPa) obtained at 20 and 25% of feldspar meet the standard of traditional ceramics requirements. The bricks obtained at 20 and 25% of feldspar and at a sintering temperature below 850 °C have good technological properties. It was observed that brick formulations with 0% of feldspar fired between 950 and 1000 °C are similar to those of 20 and 25% of feldspar fired at 850 °C).Highlights

The alluvial clays from Monoun characterized have highest proportion of kaolinite and good mechanical properties (950 and 1050 °C).

Thin section microscopic analysis of Batie feldspar revealed essentially perthites.

The brick formulations with 0% of feldspar fired between 950 and 1050 °C are similar to those of 20 and 25% of feldspar fired at 850 °C.
