Estimation of basement rocks depth has been done in Padang State University, Air Tawar campus. The research that uses Dipole-dipole resistivity geoelectrical method was aimed to determine the depth, resistivity value and the kinds of basement rocks. Data were collected by Ares Multielectrode in 4 lines. Processing of data was done using Res2dinv software with Robust Constraint inversion and it results 2D model of earth’s surface that consists of depth and resistivity value. The result of this research shows that there are basement rocks around sounding point 00053’44,0”S and 100020’79,8”E in 1st line and sounding point 00053’53,1”S and 100021’02,8”E in 2nd line at depth of more than 25,2 m with resistivity value 513 – 622 Ωm and 632 – 2150 Ωm. Basement rocks are also found in 3rd line around sounding point 00053’48,9”S dan 100020’50,6”E at depth of more than 21,85 m with resistivity value 596,5 – 734 Ωm, while 4th line at sounding point 00053’55,7”S and 100021’02,3”E did not find basement rocks. Possibility of basement rocks in 4th line are at depth of more than 29,5 m. Basement rocks that are found in this research is interpreted as Andesite. Information about basement rocks can be used for construction planning in Padang State University, Air Tawar campus.
Autistic traits are related to worse performance in a volatile reward learning task despite adaptive learning rates

Published: November 2019

Recent theories propose that autism spectrum disorder (ASD) is characterized by an impairment in determining when to learn and when not. We investigated this by estimating learning rate in environments varying in volatility and uncertainty. Specifically, we correlated autistic traits (in 163 neurotypical participants) with modelled learning behavior during probabilistic reward learning under three conditions: a Stationary Low Noise condition with stable reward contingencies, a Volatile condition with changing reward contingencies, and a Stationary High Noise condition where reward probabilities for all options were 60%, resulting in an uncertain, noisy environment. Consistent with earlier findings, we found less optimal decision-making in the Volatile condition for participants with more autistic traits. However, we observed no correlations between underlying adjustments in learning rates and autistic traits, suggesting no impairment in updating learning rates in response to volatile versus noisy environments. Exploratory analyses indicated that impaired performance in the Volatile condition in participants with more autistic traits, was specific to trials with reward contingencies opposite to those initially learned, suggesting a primacy bias. We conclude that performance in volatile environments is lower in participants with more autistic traits, but this cannot be unambiguously attributed to difficulties with adjusting learning rates.
"Do the Right Thing" for Whom? An Experiment on Ingroup Favouritism, Group Assorting and Moral Suasion
Authors: Bilancini Ennio , Boncinelli Leonardo , Capraro Valerio , Celadin Tatiana , Di Paolo Roberto
Published: November 2019

In this paper we investigate the effect of moral suasion on ingroup favouritism. We report a well-powered, pre-registered, two-stage 2x2 mixed-design experiment. In the first stage, groups are formed on the basis of how participants answer to a set of questions, concerning non-morally relevant issues in one treatment (assortativity on non-moral preferences), and morally relevant issues in another treatment (assortativity on moral preferences). In the second stage, participants choose how to split a given amount of money between participants of their own group and participants of the other group, first in the baseline setting and then in a setting where they are told to do what they believe to be morally right (moral suasion). Our main results are: (i) in the baseline, participants tend to favour their own group to a greater extent when groups are assorted according to moral preferences, compared to when they are assorted according to non-moral preferences; (ii) the net effect of moral suasion is to decrease ingroup favouritism, but there is also a non-negligible proportion of participants for whom moral suasion increases ingroup favouritism; (iii) the effect of moral suasion is substantially stable across group assortativity and four pre-registered individual characteristics (gender, political orientation, religiosity, pro-life vs pro-choice ethical convictions).

Rejecting white distraction: a critique of the white logic and white methods in academic publishing
Authors: Buggs Shantel , Sims Jennifer , Kramer Rory
Published: November 2019

This critical reply engages in a critique of the prominence of “white logic” and “white methods” (Zuberi and Bonilla-Silva 2008) in academic publishing. We assess how the construction and proliferation of white knowledge(s) shapes analysis and interpretation, argumentation, peer review, and ultimately, publication. We call for a rejection of what we name “white distraction” and encourage the academic community to move toward more inclusive and decolonial modes of thinking, reviewing, and publishing.
Cycles of Invisibility: The Limits of Transparency in Dealing with Scientific Misconduct
Authors: Hesselmann Felicitas , Reinhart Martin
Published: November 2019

Sanctions for plagiarism, falsification, and fabrication in research are primarily symbolic. This paper investigates sanctions for scientific misconduct and their preceding investigation processes as visible and legitimate symbols. Using three different data sources (retraction notices, expert interviews, survey of scientists), we show that sanctions for scientific misconduct operate within a cycle of visibility, in which sanctions are highly visible, while investigation and decision-making procedures remain mostly invisible. This corresponds to high levels of acceptance for sanctions in the scientific community, but rather low acceptance of the respective authorities. Such a punitivity in turn exacerbates confidentiality concerns, so that authorities become even more secretive. We argue that punitivity towards scientific misconduct is driven by such a cycle of invisibility.

Authors: Colvin Eamon G. H. , Tobon Juliana I. , Jeffs Lisa , Veltman Albina
Published: November 2019

The current study investigated the service access pathways of transgender youth at a mental health clinic. Demographic and service information from youth (aged 17–25) at a Canadian mental health clinic (n = 1,504) was collected. Four separate chi-square analyses were conducted to measure potential differences in service access between cisgender and gender diverse clients (those identifying as transgender, gender queer, non-binary, or other). Compared to cisgender clients, transgender and gender diverse clients were significantly more likely to self-refer for treatment. These findings highlight the importance of a self-referral option for young gender diverse clients and provide needed data about the mental health service access of transgender youth.

Published: November 2019

The glass formation, crystallization behavior, and soft magnetic properties of Fe80−xNbxB20 (x = 3, 6, and 9) and Fe82.5−yNbyB17.5 (y = 3.5, 5, 6, and 7) metallic glasses prepared by melt spinning were investigated. Differential scanning calorimetry analysis indicated that an increased Nb content results in increased thermal stability and glass-forming ability for both Fe80−xNbxB20 and Fe82.5−yNbyB17.5 glassy alloys. The supercooled liquid region increases from 26 to 50 K for Fe80−xNbxB20 alloys and from 32 to 48 K for Fe82.5−yNbyB17.5 alloys. Magnetic measurements reveal that saturation magnetization ranges from 65 to 137 emu g−1 for Fe80−xNbxB20 glassy alloys and varies from 91 to 121 emu g−1 for Fe82.5−yNbyB17.5 glassy alloys. The superior magnetic properties, high glass-forming ability, and low cost of raw materials make the current Fe–Nb–B ternary alloys promising for potential applications in the electronics industry.
Characterization of aluminum alloy microstructures by means of synchrotron X-ray micro-tomography – a simple toolchain for extracting quantitative 3D morphological features

Published: November 2019

One fundamental topic in metallography is determining relations between microscopic arrangements of phases and defects, and macroscopic properties (such as tensile strength, effective stiffness tensor, effective conductivity, permeability) which are important for materials application. For multiphase materials such as aluminum–silicon alloys our work demonstrates how – in particular – three-dimensional geometric microstructure characteristics, such as particle sphericity, connectivity and contiguity can be measured accurately from 3D X-ray computed tomography scans. This study details a simple yet very effective imaging toolchain for measuring these quantities. By tailoring the three-dimensional morphology of the alloys’ phases through composition, cooling and thermo-mechanical treatment one can establish a multidimensional materials database. For a given function and application, such a database would allow for optimized selection of alloy and processing, e.g. using a material which is specifically designed and produced according to its properties. The extraction of meaningful stochastic parameters from 3D CT scans of metallic alloys is therefore highly important.

Published: November 2019

The thyroid gland is an important organ that is involved in the regulation of homeostasis and adaptation in various pathological conditions. However, the question of the study of the proliferative activity of thyroid cells by flow cytometry is still poorly understood. Purpose of study: to investigate the indices of the cell cycle and DNA fragmentation of thyroid cells in rats against the background of infusion of 0.9% NaCl solution, lactoprotein with sorbitol or HAES-LX 5%. Experimental studies were performed on 90 white male rats weighing 160-180 g. Infusion of 0.9% NaCl solution, lactoprotein with sorbitol or HAES-LX 5% was performed in the inferior vena cava after its catheterization in aseptic conditions through the femoral vein. The infusions were performed once a day for the first 7 days. Trunk catheterization and decapitation of animals (after 1, 3, 7, 14, 21, and 30 days) were performed under propofol anesthesia (60 mg/kg i/v). Within the framework of the agreement on scientific cooperation between the Research Center of National Pirogov Memorial Medical University, Vinnytsya and the Department of Histology, Cytology and Embryology of the Odessa National Medical University (from 01/01/2018), DNA content in the nuclei of thyroid cells of rats was determined by flow DNA cytometry. Cell cycle analysis was performed using the software FloMax (Partec, Germany) in full digital accordance with the mathematical model, which determined: G0G1 – the percentage of cells of the phase G0G1 to all cells of the cell cycle (DNA content = 2c); S – the percentage of the phase of DNA synthesis to all cells of the cell cycle (DNA content > 2c and < 4c); G2+M – the percentage ratio of the G2+M phase to all cells in the cell cycle (DNA = 4c). Determination of DNA fragmentation (SUB-G0G1, apoptosis) was performed by isolating the RN2 region on DNA histograms before the G0G1 peak, indicating nuclei of cells with a DNA content < 2c. The statistical processing of the obtained results was carried out in the license package “STATISTICA 6.1” using nonparametric estimation methods. The data obtained showed a virtually identical pattern of rat cell cycle and DNA fragmentation of the thyroid gland cells at all study times against the use of 0.9% NaCl solution, lactoprotein with sorbitol or HAES-LX 5%. Thyroid cells in rats are predominantly in the inactive phase of DNA synthesis (G0G1) (90.32% – 91.88%), significantly fewer cells are in the G2+M phase (7.56% – 9.17%), and there is a small percentage of cells in the S-phase (DNA synthesis) (0.52% – 0.67%) and the SUB-G0G1 interval (DNA fragmentation, apoptosis) (2.23% – 2.81%). We can state that the activity of the main part of the thyroid gland is rather low without pathological irritation.
Borders and justice
Authors: Bosworth Mary
Published: November 2019

In this piece I offer an overview of the theme section and reflect on the relationship between academic studies and social justice. By comparing anthropology with my home discipline of criminology, I point to some shared and distinct contributions practitioners in these fields can make to our understanding about border control. Without being too pessimistic, I warn about the limits of ‘humanizing’ research subjects as a means to bring about progressive change, and suggest instead, drawing on the work of the theme section, that more needs to be done alongside and with individuals and local communities.
DICKSON CONJECTURE PROOF
Authors: BADO OLIVIER IDRISS
Published: November 2019

In 1904, Dickson [6] stated a very important conjecture. Now people call it Dickson’s conjecture. In 1958, Schinzel and Sierpinski [3]generalized Dickson’s conjecture to the higher order integral polynomial case. However, they did not generalize Dickson’s conjecture to themultivariable case. In 2006, Green and Tao [9] considered Dickson’sconjecture in the multivariable case and gave directly a generalizedHardy-Littlewood estimation. But, the precise Dickson’s conjecture inthe multivariable case does not seem to have been formulated. In thispaper, based on the idea in [8] a partial proof of Dickson's Conjecture is provided .Let $\{a_ {1},a_{2},....a_{k}\}$ the set of $k$ linear prime admissible , $t \geq 1$, $q_{a_{t}}$ be the smallest prime number dividing $a_{t}$ and $\omega(q_{a_{t}})$ its order by arranging the prime numbers in ascending order.$\beta_{j}(\sqrt{n})$ the number of prime $p\leq \sqrt{n}$ such that $ a_{j}p+b_{j}$ is prime .Let \begin{eqnarray}G(\omega(q_{a_{t}}))=\left[ \frac{1}{\phi(a_{t})}+ \frac{ 1}{q_{a_{t}}\phi(a_{t})} -\frac{1+q_{a_{t}}}{q_{a_{t}}\phi(a_{t})}\prod_{i=1}^{\omega(q_{a_{t}})-1}\left[ 1-\frac{1}{p_{i}^{\sigma^{-1}(i)}(p_{i}-1)} \right]\right]\\R(r,t)=\frac{1}{\phi(a_{t})}\left[1-\prod_{i=\omega(q_{a_{t}})+1,p_{i}\mid a_{t}}^{r}\left[ 1-\frac{1}{p_{i}^{\sigma^{-1}(i)}} \right]\prod_{i=\omega(a_{t})+1,p_{i}\nmid a_{t}}^{r}\left[ 1-\frac{1}{p_{i}^{\sigma^{-1}(i)-1}(p_{i}-1)}\right]\right]\\\mu(k,r) = \sum_{t=1}^{k}\Pi(a_{t}n+b_{t})\prod_{i=1}^{r}\left[ \frac{\prod_{p\mid a_{i}}p^{v_{p}(a_{i})}p_{i}-1}{\prod_{p\mid a_{i}}p^{v_{p}(a_{i})}p_{i}}\right]\end{eqnarray}Let $ H(n)$ the number of prime $p$ less that $n$ such that :$ \forall i \leq k,a_{i}p+b_{i}$ is prime and $ Q(n)$ the number of prime such $\exists i \leq k ,a_{i}p+b_{i}$ is primeWe show that :\begin{eqnarray}H(n)-Q(\sqrt{n})\sim_{+\infty }\Pi(k,n)-\mu(k,r)\\Q(n)-Q(\sqrt{n})\sim_{+\infty }\Pi(k,n)-\sum_{t=1}^{k}\Pi(a_{t}n+b_{t})\left[G(\omega(q_{a_{t}}))+ R(r,t)\right]\end{eqnarray} Where $ \Pi(k,n)=\Pi(\min(a_{1},a_{2},..a_{k})n+\max(b_{1},b_{2},..b_{k}))$ \end{center}

Published: November 2019

The forecast geothermal resources of Kamchatka are sufficient to generate 3900 MW of electrical energy. The same resources for heat supply are estimated at a capacity of 1350 MWt (thermal). Thermohydrodynamic TOUGH2 modeling of exploitation of already identified productive hydrogeothermal reservoirs with installed energy properties allows us to predict: 1) the possibility of increasing the electrical performance of already operating areas of the Mutnovsky field up to 105 MW and the Pauzhetsky field up to 11 MW using binary technologies; 2) the possibility of increasing heat generation at the Paratunskoye field with submersible pumps up to 216 MWt, which will fully ensure the heat consumption of the district heating systems of Petropavlovsk-Kamchatsky.

The paper presents the results of the ongoing work on the method of the long-term seismic forecast (LTSF) for the Kuril-Kamchatka Arc. The method is based on seismic gaps and seismic cycle patterns. The work also reveals the most important trends of the method development over the prior decade. Based on the main methodology the long-term forecast is given for the next 5 years from VI 2019 to V 2024 period, for the most active part of the regions seismogenic zone. The seismic cycle stages are predicted for the next five years, the normalized characteristic of the weak earthquakes (A10) amount, the earthquakes with the medium magnitudes expecting with the 0.8, 0.5 and 0.15 probabilities, the maximum expected magnitudes and the strongest with the M 7.7 earthquakes probabilities for 20 of its zones. The famous works of S.A. Fedotov resulted in further research of the regional seismic processs spatial and temporal features within the 2017 period, including the strongest (M = 7.7) July 17, 2017 Near-Aleutian Earthquake. The results confirm close seismic process relation in the most seismically dangerous, according to the LTSF data zones and major events in the region itself and the adjacent seismic regions, as well as the current very high seismic hazard in some zones of the Kuril-Kamchatka Arc and the need to continue and increase the works being done for earthquake resistance and seismic safety in the most endangered zones and of course in administrative center of Kamchatka the Petropavlovsk-Kamchatskii city.
New bounds on the strength of some restrictions of Hindman’s Theorem
Authors: Carlucci Lorenzo , Kołodziejczyk Leszek Aleksander , Lepore Francesco , Zdanowski Konrad
Published: November 2019

The relations between (restrictions of) Hindman’s Finite Sums Theorem and (variants of) Ramsey’s Theorem give rise to long-standing open problems in combinatorics, computability theory and proof theory. We present some results motivated by these open problems. In particular we investigate the restriction of the Finite Sums Theorem to sums of at most two elements, which is the subject of a long-standing open question by Hindman, Leader and Strauss. We show that this restriction has the same proof-theoretic and computability-theoretic lower bound that is known to hold for the full version of the Finite Sums Theorem. In terms of reverse mathematics it implies [Formula: see text]. Also, we show that Hindman’s Theorem restricted to sums of exactly n elements is equivalent to [Formula: see text] for each [Formula: see text], provided a certain sparsity condition is imposed on the solution set. The same results apply to bounded versions of the Finite Union Theorem, in which such a sparsity condition is already built-in. Further we show that the Finite Sums Theorem for sums of at most two elements is tightly connected to the Increasing Polarized Ramsey’s Theorem for pairs introduced by Dzhafarov and Hirst. The latter reduces to the former in the technical sense known as strong computable reducibility.
Modelling and predicting User Engagement in mobile applications

Published: November 2019

The mobile ecosystem is dramatically growing towards an unprecedented scale, with an extremely crowded market and fierce competition among app developers. Today, keeping users engaged with a mobile app is key for its success since users can remain active consumers of services and/or producers of new contents. However, users may abandon a mobile app at any time due to various reasons, e.g., the success of competing apps, decrease of interest in the provided services, etc. In this context, predicting when a user may get disengaged from an app is an invaluable resource for developers, creating the opportunity to apply intervention strategies aiming at recovering from disengagement (e.g., sending push notifications with new contents).In this study, we aim at providing evidence that predicting when mobile app users get disengaged is possible with a good level of accuracy. Specifically, we propose, apply, and evaluate a framework to model and predict User Engagement (UE) in mobile applications via different numerical models. The proposed framework is composed of an optimized agglomerative hierarchical clustering model coupled to (i) a Cox proportional hazards, (ii) a negative binomial, (iii) a random forest, and (iv) a boosted-tree model. The proposed framework is empirically validated by means of a year-long observational dataset collected from a real deployment of a waste recycling app. Our results show that in this context the optimized clustering model classifies users adequately and improves UE predictability for all numerical models. Also, the highest levels of prediction accuracy and robustness are obtained by applying either the random forest classifier or the boosted-tree algorithm.
The consequences of blockchain architectures for the governance of public services: A case study of the movement of excise goods under duty exemptions
Authors: Allessie D. , Janssen M. , Ubacht J. , Cunningham S. , van der Harst G.
Published: November 2019

Blockchain technology has the potential to provide public services directly to the public. This challenges the need for public organizations, who traditionally provided these services. Much of the current work is focused on the technology, whereas the influence on public administration structure has gained less attention. The goal of this paper is to investigate the impact of blockchain technology on the governance of public service provision. For this, we performed a case study of an EU-wide system that monitors the movement of excise goods under duty suspension. We developed two scenarios for blockchain technology’s use based on a permissionless blockchain architecture on the one hand and a permissioned one on the other. The scenarios were evaluated based on their impact on transaction validation, data quality and governance. The findings show that blockchain technology alone cannot be an alternative for the current data quality controls, equal access assurances and adaptations to legislation conducted by public administrations. As such, governments will remain playing a key role in registration of documents and assets, however, the governance will likely change depending on the type of blockchain architecture.
Hormone Therapy and Effects on Sporadic Alzheimer’s Disease in Postmenopausal Women: Importance of Nomenclature
Authors: Yare Katrine , Woodward Michael
Published: November 2019

Numerous observational studies have suggested that hormone therapy (HT) might protect postmenopausal women against cognitive decline and Alzheimer’s disease (AD). However, because of the significant disparity between results, especially those between observational and randomized controlled trials (RCT), this postulate remains unproven. A significant contributing factor to these inconsistencies is the loose use of the generic definitions of estrogens and progestogens with most studies not delineating the clear differences between non-endogenous and endogenously identical (bioidentical) hormones, their molecular binding affinities and actions, and resultant metabolites. This is highlighted by the generalized terminological use of HT, which is often used to encompass significantly disparate hormonal formulations without clear demarcation. This has impacted and continues to significantly influence interpretations of data, meta-analyses, observational studies, etc., relevant to AD. To progress forward and allow unbiased interpretation, it is no longer acceptable to group HT formulations together as a homogenous group. This will also allow differentiation between compounds that exhibit beneficial actions and those that do not and whether these effects are specific or generalized. The role of the endogenous hormones, 17 beta-oestradiol (E2) and progesterone (P4), in the development of sporadic AD in postmenopausal women is also examined.
In utero congenital chylothorax treatment with fetal thoracoamniotic shunt: Case report
Authors: Hannah D.M. , Badell M.L. , Woodham P.C.
Published: November 2019

BACKGROUND:

Fetal pleural effusions are a rare fetal anomaly that may result from congenital chylothorax. Severe cases lead to chest compression with resulting pulmonary hypoplasia and possible neonatal demise. Fetal thoracoamiontic shunt (TAS) placement may decrease the amount of pleural effusion and improve lung expansion.

CASE:

A 30-year-old primigravida at 29 2/7 weeks’ gestation presented with fetal bilateral pleural effusions with no identifiable genetic or structural abnormalities. TAS placement accomplished decompression of the left fetal chest. The neonate was delivered at 33 3/7 weeks and required minimal respiratory support with no apparent long term complications at discharge.

CONCLUSION:

This case demonstrated that fetal intervention with TAS placement can improve neonatal outcomes. Referral to an MFM specialist capable of TAS should be considered for isolated fetal bilateral pleural effusion.
Combining semantic graph and probabilistic topic models for discovering coherent topics
Authors: Allahyari Mehdi , Pouriyeh Seyedamin , Kochut Krys
Published: November 2019

Probabilistic topic models, which frequently represent topics as multinomial distributions over words, have been extensively used for discovering latent topics in text corpora. However, because topic models are entirely unsupervised, they may lead to topics that are not understandable in applications. Recently, several knowledge-based topic models have been proposed which primarily use word-level domain knowledge in the model to enhance the topic coherence and ignore the rich information carried by entities (e.g, persons, locations, organizations, etc.) associated with the documents. Additionally, there exists a vast amount of prior knowledge (background knowledge) represented as Linked Open Data (LOD) datasets and other ontologies, which can be incorporated into the topic models to produce coherent topics. In this paper, we introduce a novel regularization entity-based topic model ( RETM), which integrates an ontology with an entity-based topic model ( EntLDA) to increase the coherence of the identified topics through the topic modeling process. Our experimental results demonstrate the effectiveness of the proposed model in improving the coherence of topics.
Safety and efficacy of anterior chamber paracentesis with simultaneous intracameral administration of 0.5% pilocarpine in dogs and cats with glaucoma of various etiologies
Authors: Бояринов Сергей , Boyarinov Sergey
Published: November 2019

Purpose. In animals with glaucoma to determine the technique for conducting ACP with simultaneous administration of a 0.5 % pilocarpine solution, to identify the dynamics of IOP reduction, as well as effectiveness of this procedure both after and in the long term. Based on analysis of data obtained, highlight the complications of this procedure.

Materials and methods. Study included 37 animals (39 eyes): 24 dogs and 13 cats with glaucoma, which, according to anamnesis, developed no more than 10 days without any preliminary ocular hypotensive therapy. All animals underwent ACP without general anesthesia or sedation. Immediately before procedure, animals were instilled with a local anesthetic in conjunctival sac (0.5% proxymethacaine). ACP was performed under 6-fold magnification using a 27G headlamp with 9 hours for right eye and 3 hours for left eye. A puncture was carried out at periphery of cornea 1 mm from limbus. Volume of aspirated AH was no more than 2 drops. After that, needle was removed from the AC. Next step was intracameral injection of 0.5% solution of pilocarpine through hole of paracentesis. Volume of injected solution did not exceed 0.3 ml. After paracentesis and administration of pilocarpine solution, subconjunctival administration of dexamethasone solution in combination with gentamicin and novocaine was performed. Immediately after ACP, antihypertensive therapy was prescribed from a combination of eye drops: synthetic analogues of prostaglandins F2α (travoprost 0.004%) in combination with non-selective beta-blockers (timolol maleate 0.5%), as well as carbonic anhydrase inhibitors (brinzolamide 1%) every 12 hours.

Results. Average IOP was in animals before ACP 60.26 ± 16.32 mmHg; immediately after procedure ― 10.15 ± 3.23 mm Hg; 1 hour after ACP ― 13.28 ± 3.09 mm Hg; after 7 days ― 17.61 ± 6.03. Immediately after intracameral administration of a 0.5% pilocarpine solution, we observed a rapid and pronounced narrowing of the pupil within 1…2 minutes. Myosis was noted for at least 1 hour after procedure. There were no adverse reactions from administration of pilocarpine solution in AC. Among complications after immediately 1 hour after the ACP, we encountered aqueous flare in 12 eyes (31% of cases) and moderate hyphema in 5 eyes (13% of cases). 7 days after procedure, no complications were observed.

Conclusion. This study shows that ACP with simultaneous intracameral administration of 0.5% pilocarpine solution is effective in dogs and cats without any significant side effects. These results allow us to offer ACP as a procedure for an emergency reduction in IOP, especially in acute attacks of glaucoma in dogs and cats.

The Impact of Non-Standard Work Arrangements and Communication Climate on Organisational and Team Identification and Work-Related Outcomes Amongst Millennials in Chile and the UK
Authors: Gleibs Ilka H. , Lizama Alvarado Andrea
Published: November 2019

Previous research has found inconsistent results on the impact of work-status (permanent vs. fixed term vs. causal work) on attitudinal and behavioural outcomes. This study explored this topic from a social identity perspective and examines the effect of communication climate, organisational and team identification on job-affective well-being, organisational commitment and intentions to recommend. In Study 1, 631 professionals working in Chile completed our survey. In Study 2, which was pre-registered, 520 professionals from the UK completed the same survey. In both studies we conducted multi-group path analyses comparing employees with three work-statuses: permanent, fixed-term, and casual workers (Study 1: n = 369, 129, and 131, respectively; Study 2: n = 438, 53, and 34, respectively). We found work-status influenced the relationship between organisational and team identification with job-affective well-being, but not with organisational citizenship behaviour or intentions to recommend. Across all groups, communication climate was an important predictor for identification measures, job-affective well-being and intention to recommend. These findings offer an understanding of the dynamics of social identification in the workplace that are related to work-status in the context of two different countries; Chile, a country that is characterised by high rates of fixed-term and casual job agreement and the UK, which has comparatively fewer non-standard work-arrangements.
Self-Esteem Relates to Expecting Others to See Us How We See Ourselves
Authors: Araiza Ashley M. , Freitas Antonio L.
Published: November 2019

We examined whether self-esteem relates to coherence between self-evaluations and anticipated evaluations by others. In two studies (total N = 279), participants twice completed a measure of their personal attributes, once from their own standpoints and once from the perspective of someone they anticipated meeting, separated by a 25-minute distractor task. Supporting our preregistered predictions, the within-person association between self- and other-ratings was stronger as a function of between-person increases in self-esteem. These effects remained after statistically controlling for self-concept clarity and for fear of negative evaluation, both of which related meaningfully to self-esteem. Together, these findings indicate that persons high in self-esteem anticipate that others will evaluate them consistently with how they evaluate themselves.
Situational Factors Influencing Receptivity to Bullshit
Authors: Brown Mitch , Keefer Lucas A. , McGrew Shelby J.
Published: November 2019

Individuals are motivated to maintain a sense of meaning, and enact cognitive processes to do so (e.g., perceiving structure in the environment). This motivation to find meaning may ultimately impact humans’ interpretation of "bullshit", statements intended to convey profundity without any meaning. Conversely, subtle cues threatening the meaningfulness of bullshit may elicit greater skepticism. Three studies tested situational factors predicted to heighten or diminish susceptibility to bullshit by changing motivations to seek meaning. We employed diverse methods including symbolic meaning threat (Study 1), social exclusion (Cyberball; Study 2), and manipulating cognitive fluency (Study 3). Taken together, the results indicate basic processes shaping the detection of meaning have implications for the appraisal of ambiguously insightful information.

Assessing Dispersivity and Expansivity of Clay Soils in the South-East of Yazd with Aim of Investigating Correlation between Them

Published: November 2019

Having knowledge about physical, chemical and mechanical properties of problematic soils is necessary when they are applied in construction projects as borrow materials or foundation, because these soils have potential to create large financial losses. This research deals with characterizing dispersive and swelling soils as problematic soils in southeast of Yazd (center of Iran) with aim of establishing a relationship between dispersivity and expansivity indices. In this regard, after performing a series of physical and chemical tests, the characteristics of the soil samples were determined, and their dispersivity degrees were specified by conducting chemical, pinhole and double hydrometer tests. Also, swelling rates of the soils were estimated using direct method (modified free swell index, MFSI) and indirect methods (different criteria developed for swelling assessment). The results showed that chemical parameters overestimate dispersivity of the soil samples (dispersive to semi-dispersive) in compared to pinhole and double hydrometer tests (slightly non-dispersive to moderately dispersive). Different expansivity degrees were defined using the direct and the indirect methods (ignorable to very high) for the soil samples. Among the empirical criteria used to evaluate the swelling potential, the AASHTO's criterion has the closest results to the MFSI in the both boreholes. Also, it revealed that as depth increases, the degree of soil dispersivity and expansivity decrease in response to the reduction of fine grain content in the samples. Finally, the correlations between dispersivity and expansivity indices, showed that sodium absorption ratio (SAR) can be used as a reasonable index to estimate soil swelling potential.
Conocimiento y consumo de alimentos funcionales en la comunidad académica de la Universidad Nacional del Chaco Austral
Authors: Britez Melisa Gladys , Romero Mara Cristina
Published: November 2019

El objetivo del presente estudio fue determinar el grado de conocimiento sobre alimentos funcionales y el nivel de consumo de los mismos en integrantes de la comunidad académica de la Universidad Nacional del Chaco Austral. Con ese fin, se aplicó una encuesta a 138 personas, empleando un muestreo no probabilístico. Se encontró que solo un 54 % de los encuestados tenía conocimiento acerca de los alimentos funcionales. Las leches fortificadas 62 %, el pan con salvado (63 %)  y  los cereales para desayuno (54 %) fueron los alimentos más incluidos en la dieta. La información obtenida nos permitirá implementar intervenciones educativas en la comunidad universitaria, con el objetivo de promover la alimentación saludable. Se propone además, a futuro, indagar sobre la relación que hacen las personas entre el término alimentos funcionales y los precios de los mismos.
Las transformaciones globales en la producción de semillas y su impacto en el conflicto por el uso propio en Argentina
Authors: Pérez Trento Nicolás
Published: November 2019

En este trabajo nos proponemos analizar algunas de las transformaciones en la producción de semillas de soja vinculadas con el conflicto desatado en la Argentina en torno al cobro de regalías por el uso propio. En particular, presentaremos la diferenciación de los capitales que intervienen en la producción de dichas semillas tras la consolidación de la biotecnología en la rama agrícola. Esto, a su vez, profundizó algunas tendencias que ya habían comenzado a manifestarse anteriormente, tales como el incremento de la inversión privada en el desarrollo de nuevas variedades y la centralización de los capitales. Esto desató una serie de conflictos, ya que los agricultores pueden reproducir semillas de soja conservando inalterada su carga genética, lo que dio lugar a la emergencia de nuevas formas de apropiar ganancias por parte de los capitales, sobre la base de limitar o impedir el uso propio.
El b-learning en los cursos semipresenciales y presenciales de la formación inicial de profesores de ciencia en Uruguay
Authors: Rodriguez Zidán Eduardo , Grilli Silva Javier
Published: November 2019

El artículo analiza el uso de las plataformas digitales en estudiantes de profesorados de ciencias, en dos modalidades de formación: presencial y semipresencial.  El diseño de la investigación es de corte mixto. Se analizan las respuestas de 396 estudiantes a una encuesta digital aplicada en 8 centros y los resultados de 17 entrevistas en profundidad. Los hallazgos indican que los futuros profesores de ciencia ingresan con frecuencia moderada a las plataformas educativas, subutilizan las herramientas digitales y acceden muy poco a otros recursos digitales gratuitos, disponibles en la web. La interactividad entre docentes y estudiantes en las aulas virtuales es moderada o baja, dependiendo de la disciplina y de la modalidad de formación. Según la percepción estudiantil, una buena práctica de uso de las aulas virtuales requiere: acceso sin restricciones al equipamiento informático e Internet, mayor uso del sistema de videoconferencias y de videos explicativos de los temas.
