Published: June 2019

Morphometric analysis is one of the important aspects of quantitative geomorphology which is primarily used to study the geometrical aspects of the landforms. The study was undertaken with the objectives of evaluating morphometric characteristic and prioritizing the watersheds of Bhadar basin based on its morphometric characteristics.  Linear, relief and aerial aspects were calculated for watershed characterization. The watersheds were ranked on the basis of high values of linear parameters and low values of shape parameters. A total of 16 watersheds 5G1B1, 5G1B2, 5G1B3, 5G1B4, 5G1B5, 5G1B6, 5G1B7, 5G1B8, 5G1B9, 5G1B10, 5G1B11, 5G1B12, 5G1B13, 5G1B14, 5G1B15 and 5G1B16 were identified in the Bhadar basin and morphometric characteristic of each watershed was determined. Highest priority indicated the greater degree of erosion in the particular watershed and it therefore priority should be given in applying soil conservation measures. It was concluded that the watershed 5G1B15 should be given highest priority because of higher erosion problems over other watersheds of Bhadar basin while 5G1B4 should be given the least priority.
Pulmonary expression of Pla2g5 during lung damage in mice induced by fipronil and lipopolysaccharide interaction
Authors: Pandit Arif Ahmed , Sethi R S
Published: June 2019

With Indian pesticide industry touching new heights each year in terms of production and sale, its ill effects on health cannot just be ignored. Humans, as well as animals, are under the constant threat of being exposed to environmental pollutants like endotoxins and pesticides which are present ubiquitously in our surroundings. Phenylpyrazoles like fipronil were introduced into the Indian market with an aim to oversee the menace of insecticide resistance and public health hazards experienced with more commonly used pesticide but its adverse effects on the pulmonary system are now being reported globally. We reported first data that the Planar cell Polarity (PCP) pathway was the top dysregulated pathway during fipronil induced lung damage. In order to further elucidate the underlying molecular mechanisms, we analysed the data generated by gene expression profiling in lung tissues using biocomputational approaches. We found Eicosanoid signalling as one of the top enriched pathways dysregulated during fipronil and or endotoxin-induced lung inflammation. Global view of genes showed Pla2g5 as top differentially expressed gene with 1.6, 3.9, 1.2, 3.1 and 4.3-folds expression in lipopolysaccharide (LPS), high dose of fipronil (9.5mg/kg) alone or in combination with LPS and low dose of fipronil (4.75 mg/kg) alone or in combination with LPS, respectively which was validated using qPCR and immunohistochemistry. The data suggest a role Pla2g5 to activate eicosanoid signalling in fipronil and or LPS induced lung inflammation in mice.

Published: June 2019

Growth attributes of Vigna mungo and Vigna radiata crop influenced by level and type of fertilizers. The present study was carried out to evaluate and compare the effects of organic (vermicompost) and inorganic (urea) fertilizers on the germination percentage and seedling growth of V. radiata (Green gram) and V. mungo (Black gram). Fresh weight and dry weight of tested plant samples at 10th days of growth stage were also determined. Vermicompost was used as organic fertilizer and urea as inorganic fertilizer. Experimental results showed that vermicompost and urea both has positive effect on seedling growth parameters of V. mungo and V. radiata [average root length (6.1cm and 6.7cm)] , shoot length (6.5cm and 8.3cm), leaf area (312.2 sq.cm and 334.1 sq.cm] as compared to control set [average root length (4.4cm and 4.3cm)] , shoot length (6cm and 5.9cm), leaf area (282.7 sq.cm and 305.5 sq.cm). But urea exerts negative effect on seed germination percentage in V. mungo and V. radiata (58% and 50%) as compared to control (77%). Vermicompost exhibited better result in above parameters in comparison to urea. V. mungo showed increased value in comparison considering V. radiata in case of organic, inorganic fertilizer treated as well as control sets. As composition of locally available fertilizers is unknown, the application of these fertilizers for improving germination percentage and growth parameters of tested crop need to be evaluated. Present work may provide the suggestive approach for usage of these tested fertilizers in field level trial.

Lead is a nonessential “grey listed” heavy metal, used in fuels, ceramics, paints and glass wares in industries and vehicles. After taking entry in aquatic ecosystem it becomes toxic and cause serious problem to plants and animals. Haematological, neurological, nephrological and histopathological effects of lead are well known. Fresh water prawn, Macrobrachium dayanum, a potential animal for freshwater aquaculture, subjected to acute and sub-acute concentration of lead nitrate (116.46 mg/l; 96h LC50 and 29.12 mg/l; 25% of 96h LC50) showed severe histopathological alterations in gills after 24, 48, 72 and 96h and 10, 20 and 30 day exposure. Chief alterations during acute exposure were thickening of gill plates, reduction in inter lameller spaces, cuticular irruption, inflammation and necrosis where as clumping of gill plates, hyperplasia, hypertrophied haemocytes with nuclear pycnosis and leakage of haemocytes in inter-lameller spaces as well as deposition of broken tissue debris near gill base were observed during sub-acute exposure. The severity of histopathological alterations was found duration dependant. Present study reveals that histological bio- markers provides complete information regarding heavy metal toxicity particularly lead to these economically important fresh water prawns, which can themselves serve as bio-indicator of worsening status of surface aquatic bodies.

do, they do not have to oppose their practice. In short, a learning in the
variability, which produces a rupture between theory and practice; staying with
what most convinces them, including negligence, which affects the patient's
safety. In the small hospital, it is a teaching based on a practice based on
scientific evidence and personalized attention, on knowing the other. Clearly
taught from the reception, to treat with caring patience and co-responsibility
in the care. The protagonists of both scenarios agree that teaching and helping
new people establish lasting and important personal relationships to feel happy
and want to be in that service or hospital. Conclusion:
There are substantial differences related to the size of the center, as to what
and how the student and the novel professional are formed. At the same time
that the meaning of value that these health organizations transmit to their
workers is inferred through the training, one orienting to the task and the
other to the person, either patient, professional or pupil and therefore
seeking the common benefit.
The Contributions of the Gallo Team and the Montagnier Team to the Discovery of the AIDS Virus
Authors: Kühne Rainer Walter
Published: June 2019

In this paper I review the main works of the teams headed by Robert Gallo and Luc Montagnier which led to the discovery of the HIV retrovirus and to the blood test with which one can prove HIV infection. I show that this discovery which saved millions of human lifes (and perhaps the survival of mankind) was made possible only (i) because Gallo's team discovered the T-cell lymphocyte growth factor with which they were able to discover the first retrovirus that infects humans (HTLV-I) and their hypothesis that AIDS is caused by a retrovirus, and (ii) because Montagnier's team detected an antibody against alpha interferon in order to enhance retrovirus production with which they were able to discover the HIV retrovirus and their examination and blood test that gave evidence that HIV causes AIDS. Their examination was improved by the Gallo team who proved without doubt that HIV is the cause of AIDS. I leave the question open whether Gallo deserved the Nobel Prize or whether the Nobel committee's decision to award the prize only to Montagnier and Barre-Sinoussi was correct.
Honest signaling in academic publishing

Academic journals provide a key quality-control mechanism in science. Yet, information asymmetries and conflicts of interests incentivize scientists to deceive journals about the quality of their research. How can honesty be ensured, despite incentives for deception? Here, we address this question by applying the theory of honest signaling to the publication process. Our models demonstrate that several mechanisms can ensure honest journal submission, including differential benefits, differential costs, and costs to resubmitting rejected papers. Without submission costs, scientists benefit from submitting all papers to high-ranking journals, unless papers can only be submitted a limited number of times. Counterintuitively, our analysis implies that inefficiencies in academic publishing (e.g., arbitrary formatting requirements, long review times) can serve a function by disincentivizing scientists from submitting low-quality work to high-ranking journals. Our models provide simple, powerful tools for understanding how to promote honest paper submission in academic publishing.

Published: June 2019

Whilst some scientists study insects, molecules, brains, or clouds, other scientists study science itself. Meta-research, or “research-on-research”, is a burgeoning discipline that investigates efficiency, quality, and bias in the scientific ecosystem, topics that have become especially relevant amid widespread concerns about the credibility of the scientific literature. Meta-research may help calibrate the scientific ecosystem towards higher standards by providing empirical evidence that informs the iterative generation and refinement of reform initiatives. We introduce a translational framework that involves (1) identifying problems; (2) investigating problems; (3) developing solutions; and (4) evaluating solutions. In each of these areas, we review key meta-research endeavors and discuss several examples of prior and ongoing work. The scientific ecosystem is perpetually evolving; the discipline of meta-research presents an opportunity to use empirical evidence to guide its development and maximize its potential.
Application of background pressure with kinematic criterion for free surface extension to suppress non-physical voids in the finite volume particle method
Authors: Quinlan Nathan , Moghimi Mohsen Hassanzadeh
Published: June 2019

Lagrangian particle methods such as smoothed particle hydrodynamics (SPH) and the finite volume particle method (FVPM) can suffer from non-physical voids in the spatial discretisation, due to the inability of numerical particles to deform as continuum fluid elements can. It is known that the situation can be improved for wall-bounded flows in SPH by adding a uniform background pressure to ensure positive absolute pressure everywhere. In this article, we investigate the application of background pressure in FVPM, and show that numerical voids grow under negative pressure and collapse under positive pressure. To use this technique in free-surface flow, however, the background pressure must be applied as an atmospheric pressure at the free surface. A kinematic criterion for free surface extension (KCFSE) to differentiate physical free surfaces from new numerical voids has been developed, supplementing the inherent capability of FVPM to identify free-surface particles robustly. The novel method enables background pressure to be applied at physical free surfaces and throughout the fluid, but not in non-physical voids, facilitating the suppression of such spurious voids. The KCFSE is validated for a translating square cylinder inside a rectangular numerical domain, with and without a free surface, and liquid in an oscillating rectangular tank.

Una terminología de teatro para organizar el patrimonio cultural universitario
Authors: Naumis Catalina , García Ariel Alejandro Rodríguez , Guadarrama Hugo
Published: June 2019

The objective of this study is to identify the functional terms in the communication on the theme of theater for an information system of university cultural spaces in the Spanish language. Regarding the terminological designation, there is a set of zones, areas, means, instruments and tools to exchange between stagehand, sound and lighting technicians, musicians, actors and artists that should be managed by those responsible for the operation of the spaces and the authorities that schedule activities. The methodology was based on the search of the terms referring to the theatrical space and the confrontation with the Art & Architecture Thesaurus (Getty Research Institute) This categorization allowed to delimit the theater universe according to its sets and their respective elements, to establish a structure that hierarchizes the theatrical space, in order to sustain the indexing and recovery of the information system in which it will be inserted. Finally, the specialists and authorities were consulted to validate the proposal.
The Value of Abstraction
Authors: Ho Mark K , Abel David , Griffiths Tom , Littman Michael L.
Published: June 2019

Agents that can make better use of computation, experience, time, and memory can solve a greater range of problems more effectively. A crucial ingredient for managing such finite resources is intelligently chosen abstract representations. But, how do abstractions facilitate problem solving under limited resources? What makes an abstraction useful? To answer such questions, we review several trends in recent reinforcement-learning research that provide insight into how abstractions interact with learning and decision making. During learning, abstraction can guide exploration and generalization as well as facilitate efficient tradeoffs---e.g., time spent learning versus the quality of a solution. During computation, good abstractions provide simplified models for computation while also preserving relevant information about decision-theoretic quantities. These features of abstraction are not only key for scaling up artificial problem solving, but can also shed light on what pressures shape the use of abstract representations in humans and other organisms.
Learning to be selfish? A large-scale longitudinal analysis of Dictator games played on Amazon Mechanical Turk
Authors: Arechar Antonio Alonso , Rand David Gertler
Published: June 2019

We investigate the role of experience playing the Dictator Game (DG) on allocations by aggregating data from 37 studies conducted on Amazon Mechanical Turk over a 7-year period. While prior evidence has shown a correlation between experience on Amazon Mechanical Turk and selfishness, it is unclear to what extent this is the result of selection versus learning. Examining a total of 27,266 decisions made by 17,791 unique individuals, our data shows evidence of significant negative effects of both selection and learning. First, people who participated in a greater total number of our studies were more selfish, even in their first game – indicating that people who are more likely to participate in our studies are more selfish. Second, a given individual tends to transfer less money over successive studies – indicating that experience with the DG leads to greater selfishness. These results provide clear evidence of learning even in this non-strategic social setting.

Collisions Between Institutional and Populist Risk Imaginaries: The “Dark Side” of Negative Asymmetric Thinking
Authors: Hagen Ryan
Published: June 2019

Expert knowledge informs the construction of public problems from gun violence to disease epidemics to climate change, and institutional actors draw on this knowledge to implement public policy to mitigate or repair the related harms. The expanding role of experts and institutions in managing risks has come at a time of declining public trust in institutions and a legitimacy crisis around expert knowledge. What happens when these tendencies collide? Previous scholarship has examined how disaster arises through failures of foresight, and how cultural-cognitive biases can prevent actors from seeing disasters coming. Less is known about the mobilization of resistance against risk management policies. This theoretical essay examines a particular category of that resistance: conspiracist discourse that frames risk as emanating primarily from perceived secret agendas of institutions and experts that explicitly claim to be acting in the public interest. This essay argues that conspiracy thinking can be best understood as rooted in a “populist risk imaginary,” which is rooted in negative asymmetry, a cultural-cognitive bias that foregrounds the possibility of worst-case outcomes. Conspiracy discourse can be understood as the “dark side” of negative asymmetry, which is otherwise used by service-oriented professionals to sharpen their foresight in preempting future dangers.
