Migrant in my own country: The long march of migrant workers in India during the COVID-19 pandemic 2020-Failure of postcolonial governments to decolonize Bihar and rebuild Indian civilization after 1947

The world is passing by way of the unprecedented disaster of COVID 19 pandemic. A big part of the world inhabitants has been dwelling underneath necessary mass quarantine, the lockdown, as a technique in the direction of slowing down the enlargement of the pandemic. This lockdown is being eased out throughout world in a part sensible method. India being one of the most populous nations is hardest hit by the pandemic and quickly the quantity of constructive circumstances is probably going to contact a million mark. Nothing has modified for the migrant workers by way of the previous three centuries, together with the first century of postcolonial India. Why are they known as migrant workers?

One of the most important phenomenons noticed during the Indian lockdown, has emerged as the long march of migrant workers from cities to their native locations. Bihar, one of the Indian provinces is the main supplier of migrant labourers for Indian agriculture and the business sectors. As depicted on social media and tv, the plight of migrants was disturbing and uncovered fashionable Indian democracy’s vulnerabilities. Many of them had to stroll on foot for 1000’s of kilometers, with their hungry households, from the industrial cities to their native locations.

Are they not residents of India? How come being Bihari-a native of Bihar province, one of the main sources of migrant workers in India, develop into a stigma? So how did the historic image of the most important accomplishments of Indian historical past, literature, science, and tradition come to be recognized with poor migrant workers’ picture? Bihar’s underdevelopment is commonly blamed on corrupt native politicians and caste politics. However, the historical past of migrant workers from Bihar and japanese Uttar Pradesh states of India is price a more in-depth consideration for doable options.

The phenomenon has a historic linkage with the fall of as soon as upon a time the nice Indian civilization; centuries of occupation, colonization, slavery, and indentured servitude. India has made regular progress in financial phrases since 1947, India’s independence from the British empire. The financial system’s dimension and rise in gross home product (GDP) are meaningless if atypical residents proceed to be disfranchised, not protected, and liberated from the colonial processes. For India’s sovereign financial growth, there isn’t a choice however to make investments in long-term and rebuild the civilization and construct a system of the indigenous Indian information financial system based mostly on the core ideas and values of the Indian civilization.

Sovereign Credit Default Swap and Stock Markets in Central and Eastern European Countries: Are Feedback Effects at Work?

 

The objective of the paper is to examine the relationship between sovereign Credit Default Swap (CDS) and inventory markets in 9 rising economies from Central and Eastern Europe (CEE), utilizing every day knowledge over the interval January 2008-April 2018. The evaluation deploys a Vector Autoregressive mannequin, specializing in the path of Granger causality between the credit score and inventory markets. We discover proof of the presence of bidirectional suggestions between sovereign CDS and inventory markets in CEE nations.

The outcomes spotlight a switch entropy of danger from the non-public to public sector over the entire interval and respectively, from the public to non-public switch entropy of danger during the European sovereign debt disaster solely in Romania and Slovenia. Another discovering that deserves explicit consideration is that the linkage between the CDS spreads and inventory markets is time-varying and topic to regime shifts, relying on world monetary situations, similar to the sovereign debt disaster. By offering insights on the inter-temporal causality of the comovements of the CDS-stock markets, the paper has important sensible implications for danger administration practices and regulatory insurance policies, underneath totally different market situations of European rising economies.

Sovereignty, privateness, and ethics in blockchain-based id administration programs

 

Self-sovereign id (SSI) options carried out on the foundation of blockchain expertise are seen as options to present digital identification programs, and even as a basis of requirements for the new world infrastructures for id administration programs. It is argued that ‘self-sovereignty’ in this context will be understood as the idea of particular person management over id related non-public knowledge, capability to select the place such knowledge is saved, and the capacity to present it to those that want to validate it.

It can also be argued that whereas it is perhaps interesting to operationalise the idea of ‘self-sovereignty’ in a slim technical sense, depreciation of ethical semantics obscures key challenges and long-term repercussions. Closer consideration to the normative substance of the ‘sovereignty’ idea helps to spotlight a spread of moral points pertaining to the altering nature of human id in the context of ubiquitous non-public knowledge assortment.

By making full use of 5-min high-frequency knowledge, and with the assist of the technique of entropy weight approach for order desire by similarities to preferrred resolution (TOPSIS), this paper builds bounce volatility spillover community of China’s monetary establishments to measure the SIFIs. ; (iii) an fascinating discovering reveals that some small monetary establishments are additionally SIFIs during the monetary disaster and can’t be ignored.

ANTI HER2 THERAPIES AGAINST BREAST CANCER

Overexpression of the HER2 protein occurs in approximately 25% of breast cancer cases, resulting in a therapeutic target of great interest against which various anti-HER2 therapies against breast cancer are being developed.

In this post we summarize the main types of anti HER2 therapies that are being incorporated into clinical practice in the approach to breast cancer.

The HER2 protein, also known as ERBB-2, is a 185 kDa tyrosine kinase receptor composed of an extracellular ligand-binding domain, a transmembrane domain, and an intracellular domain with tyrosine kinase activity.

By binding to EGF (Epidermal Growth Factor) ligands, such as TGF-α , AR, EPR or NRG1 , among others, the formation of heterodimers is activated that activate various transduction cascades, resulting in increased proliferation, differentiation, cell mobility and survival.

Overexpression of this receptor and its constant activation leads to uncontrolled cell division and carcinogenesis.

After focusing on the HER2 receptor as a therapeutic target, various treatments aimed at blocking and deactivating it have been developed as a mechanism to treat HER2 + breast cancer.

There are currently three types of anti-HER2 therapies for breast cancer : monoclonal antibodies, TKIs (tyrosine kinase inhibitors) and ADCs (Antibody-drug conjugates).

MONOCLONAL ANTIBODIES (MAB)

Anti HER2 monoclonal antibodies are large molecules with monovalent affinity, produced using recombinant DNA technology.

Its mechanism of action is based on blocking the extracellular ligand binding domain of the HER2 receptor, thus reducing the neoplastic actions of HER2 heterodimers. At the same time, the HER2-antibody complex is internalized and destroyed by the target cell, reducing the number of available HER2 receptors.

Examples of monoclonal antibodies currently used as treatment in breast cancer include humanized antibodies trastuzumab and pertuzumab.

You can expand the information in this entry about Monoclonal Antibodies against breast cancer .

TYROSINE KINASE INHIBITORS (TKI)

Tyrosine kinase inhibitors are smaller molecules than monoclonal anti-HER2 antibodies, and their mechanism of action is based on the inhibition of phosphorylation of the intracellular tyrosine kinase domain of the HER2 receptor.

Most of these compounds target more than one HER receptor, allowing them to simultaneously block two or more components of the heterodimer.

The binding of these compounds to the HER2 receptor can be reversible as in the case of Lapatinib , or irreversible as in the case of Canertinib .

ANTIBODY-DRUG CONJUGATES (ADC)

ADCs are a special type of therapeutic antibody, consisting of an anti-HER2 monoclonal antibody conjugated to a chemotherapeutic drug. Its mechanism of action is based on the internalization of the antibody-drug complex and its intracellular cytotoxic activity.

The selection of the antigen for the development of this type of therapeutic agents is critical to achieve maximum specificity and consequently less toxicity, with optimal antigens being those that are expressed with high density on the surface of cancer cells, and do not do so in healthy cells.

An example of ADC against breast cancer would be trastuzumab emtansine (T-DM1).

5 METHODS TO QUANTIFY PROTEINS

The precise quantification of the proteins in a sample is essential for studying them in an infinity of research areas.

While the quantification of a specific protein can be carried out by means of tests such as Western Blot or ELISA , by mass spectrometry (MS) or by other methods such as those based on nanoparticles, there are tests that allow quantifying the concentration of total protein present in a shows.

This last case is the one we focus on this week, compiling a brief description of the 5 main methods to quantify total proteins .

1.- BICINCHONINIC ACID (BCA)
  • Concentration range : 20-2000 ug / ml
  • Features :
    • Developed in 1985
    • Colorimetric test where the absorbance will be proportional to the concentration of protein present in the sample
    • Two-step reaction:
      • Formation of protein-copper ion complexes
      • Formation of a Cu-BCA chelate resulting in an intense purple coloration that absorbs at 562nm
    • It is a recommended method in the case of samples containing> 5% detergents and / or denaturing agents such as urea or guanidinium chloride.
  • Limitations :
    • Samples containing substances that interact with copper, such as ammonia, like EDTA, reducing sugars, or lipids, may interfere with this assay.
2.- ULTRAVIOLET (UV) ABSORPTION
  • Concentration range : 0.1-100 ug / ml
  • Features :
    • This method, by measuring the characteristic absorption of tryptophan and tyrosine at 280nm, estimates the amount of protein present in the sample.
  • Limitations :
    • It is incompatible with protein extraction methods that use detergents and / or denaturing agents.
    • It is not a specific method for proteins, since other compounds that could be in the sample also absorb at 280nm (such as alcohols or nucleic acids, among others)
3.- BRADFORD OR COOMASIE BLUE TEST
  • Concentration range : 20-2000 ug / ml
  • Features :
    • Method described in 1976
    • It is characterized by being a quick, simple and compatible method with reducing agents used to stabilize proteins in solution.
    • The negatively charged Coomasie blue stain binds to positively charged proteins.
    • It mainly binds to arginine, tryptophan, tyrosine, histidine and phenylalanine residues.
    • The solution stain is red and absorbs at 465nm, while binding to the basic amino acids of a protein it turns blue and absorbs at 595nm.
    • The absorbance measurement is compared with the values ​​of a standard curve to determine the protein concentration of the sample.
  • Limitations :
    • Not valid for detecting proteins of <3kDa
    • It is incompatible with detergents such as SDS or Triton X-100
4.- LOWRY’S ESSAY
  • Concentration range : 10-1000 ug / ml

    • One of the most widely used methods to quantify proteins was developed in 1951
    • It is a very sensitive and precise test
    • Like the BCA assay, a two-step reaction occurs:
      • Formation of Cu-N complexes (present in the protein)
      • The tyrosine and tryptophan complexes react with the Folin-Ciocalteau rectifier, giving rise to a greenish-blue color that absorbs between 650 and 750nm.
    • The absorbance measurement is compared with the values ​​of a standard curve to determine the protein concentration of the sample.
  • Limitations :
    • It is incompatible with certain chemical reagents in common use such as Tris, EDTA, DDT, 2-mercaptoethanol, carbohydrates, etc.
5.- CBQCA (3- (4-CARBOXYBENZOYL) QUINOLINE-2-CARBOXYDEHYDE) ASSAY
  • Concentration range : 100 ng – 1500 ug / ml
  • Features :
    • It is a highly sensitive fluorogenic agent that is used for the detection of primary amines in proteins.
    • The intensity of the fluorescence emitted will be directly proportional to the concentration of protein present in the sample.
    • Does not interact with lipid compounds

The Embodied Brain of SOVEREIGN2: From Space-Variant Conscious Percepts During Visual Search and Navigation to Learning Invariant Object Categories and Cognitive-Emotional Plans for Acquiring Valued Goals.

This article develops a mannequin of how reactive and deliberate behaviors work together in actual time. Controllers for each animals and animats want reactive mechanisms for exploration, and realized plans to effectively attain purpose objects as soon as an surroundings turns into acquainted.

The SOVEREIGN mannequin embodied these capabilities, and was examined in a 3D digital actuality surroundings. Neural fashions have characterised vital adaptive and clever processes that weren’t included in SOVEREIGN. A serious analysis program is summarized herein by which to constantly incorporate them into an enhanced mannequin known as SOVEREIGN2.

Key new perceptual, cognitive, cognitive-emotional, and navigational processes require suggestions networks which regulate resonant mind states that assist aware experiences of seeing, feeling, and realizing. Also included are computationally complementary processes of the mammalian neocortical What and Where processing streams, and homologous mechanisms for spatial navigation and arm motion management.

These embody: Unpredictably shifting targets are tracked utilizing coordinated easy pursuit and saccadic actions. Estimates of goal and current place are computed within the Where stream, and can activate strategy actions. Motion cues can elicit orienting actions to deliver new targets into view.

Cumulative motion estimates are derived from visible and vestibular cues. Arbitrary navigational routes are incrementally realized as a labeled graph of angles turned and distances traveled between turns.

Noisy and incomplete visible sensor knowledge are remodeled into representations of visible type and movement. Invariant recognition classes are realized within the What stream. Sequences of invariant object classes are saved in a cognitive working reminiscence, whereas sequences of motion positions and instructions are saved in a spatial working reminiscence.

Stored sequences set off studying of cognitive and spatial/motor sequence classes or plans, additionally known as listing chunks, which management deliberate selections and actions towards valued purpose objects. Predictively profitable listing chunk mixtures are selectively enhanced or suppressed by way of reinforcement studying and incentive motivational studying.

Expected vs. surprising occasion disconfirmations regulate these enhancement and suppressive processes. Adaptively timed studying permits consideration and motion to match process constraints. Social cognitive joint consideration permits imitation studying of expertise by learners who observe academics from totally different spatial vantage factors.

Twenty Years of Military Prehospital Care within the Eastern Sovereign Base Area, Cyprus.

The Medical Reception Station (MRS) in Dhekelia supplies a prehospital emergency care (PHEC) service for the Eastern Sovereign Base Area and surrounding Cypriot cities.

This service has been evaluated beforehand however some vital elements of care haven’t but been measured. The major goal of this examine was to undertake essentially the most complete service analysis of the demand for the PHEC service at MRS Dhekelia over a 12-month interval.

The secondary goal of this examine was to evaluate findings in 2018 to these in 1995-1998 and 2013-2016.All calls to the PHEC crew between 01/07/2017 and 30/06/2018 had been reviewed and in contrast with beforehand reported knowledge from 1995 to 1998 and 2013 to 2016. Data had been collected from the prevalence ebook, the logbook utilized by the PHEC crew to file the small print of every name.There had been 164 calls to the PHEC service in the course of the present examine interval. The quantity of activations has decreased for the reason that 2013-2016 interval however stays larger than 1995-1998.

In each month there was a name to a scene the place a couple of casualty was current, with the very best quantity being 9 sufferers at one name. More calls had been obtained in the course of the day (55%). There had been extra calls as a result of of trauma than medical complaints (55% vs 45%). Trauma calls have decreased over 20 years.

The frequency of neurological and psychiatric complaints has elevated over 20 years.The PHEC service at MRS Dhekelia is ceaselessly used. The crew constantly face with scenes with a couple of casualty. Trauma is turning into much less frequent however psychiatric and neurological complaints are more and more frequent. These findings are vital for coaching and service provision.

Customising global climate science for national adaptation: A case study of climate projections in UNFCCC’s National Communications.

Customising global climate science for national adaptation: A case study of climate projections in UNFCCC's National Communications.

Countries differ markedly in their manufacturing of climate science. While richer nations are sometimes house to a spread of climate fashions, information infrastructures and climate consultants, poorer sovereigns typically lack these attributes.

However, much less is thought about international locations’ capability to make use of global climate science and customise it into merchandise informing national adaptation. We use a novel global dataset, the UNFCCC National Communications, to carry out a global documentary evaluation of scientific submissions from particular person international locations (n = 189).

Comparing international locations’ climate projections with their competence in publishing climate science, our analysis examines the existence of geographical divides. Although international locations proficient in publishing climate science use extra advanced climate modelling strategies, key traits of climate projections are extremely related across the globe, together with multi-model ensembles of Global Circulation Models (GCMs).

This stunning result’s made potential as a result of of the use of pre-configured climate modelling software program packages. One concern is that these instruments limit customisation, akin to country-specific observations, modelling data, and visualisation.

Such instruments could due to this fact disguise a brand new geographical divide the place international locations with larger scientific capacities are in a position to inform what goes into these software program packages, whereas decrease scientific capability international locations are dependent upon these selections – whether or not helpful for them or not.

Our analysis means that free-to-use modelling and coaching efforts could unwittingly limit, reasonably than foster, international locations’ capability to customize global climate science into nationally related and legit climate data.

Pension and state funds dominating biomedical R&D funding: fiduciary responsibility and public well being.

Who advantages from the business biomedical analysis and growth (R&D)? Patients-consumers and investors-shareholders have historically been considered as two distinct teams with conflicting pursuits: shareholders search most income, sufferers – most medical profit. However, what occurs when sufferers are the shareholders?

With billions of {dollars} of public threat capital channeled into the drug growth business, analysing the advanced monetary structure and the market for company management is important for understanding business’s traits, akin to pricing methods or R&D priorities.Adding investments by governmentally-mandated retirement schemes, central and promotional banks, and sovereign wealth funds to tax-derived governmental financing reveals that almost all of biomedical R&D funding is public in origin.

Despite this, even in the high-income international locations sufferers might be denied entry to efficient therapies as a consequence of their excessive value. Since these prices are set by the drug growth companies which can be owned in substantial half by the retirement accounts of mentioned sufferers, the advanced monetary structure of biomedical R&D could also be inconsistent with the targets of the last word beneficiaries.

The divergence in financial and public well being efficiency of the drug growth business is resultant from its monetary underwriting by enormously expanded pension schemes, governmentally mandated to symbolize the pursuits of “captive” beneficiaries, in addition to related policymaker-designed funding flows, whose requirements of transparency, accountability and illustration are considerably decrease than that of governments themselves. Strengthening these components of institutional design and thus making certain lively accountable shareholding in the curiosity of the patients-savers is an under-utilised, however probably high-impact alternative for advancing public well being.

Sovereign rating after private and official restructuring.

Sovereign rating after private and official restructuring.

This paper research the connection between sovereign debt (last) restructuring and sovereign scores, by distinguishing between industrial and official debt and by contemplating the collectors’ loss (haircut). Institutional Investor’s index is taken as a measure of a rustic’s creditworthiness.

We discover that whereas a restructuring with private collectors appears to contain some reputational prices, “official defaulters” aren’t affected (or might even profit) by the restructuring episodes.

Using the Synthetic Control Method, we discover additional proof for the heterogeneity of the financial affect of debt restructurings, confirming that official and private restructurings might have totally different prices and then induce selective defaults.

Sovereign Dignity, Nationalism and the Health of a Nation: A Study of China’s Response in Combat of Epidemics.

This paper seeks to know the function of nationalism in China’s coverage in direction of the fight of rising infectious ailments. By finding nationalism as an element which facilitates or impedes international governance and worldwide collaboration, this paper explores how nationalism influences China’s political decision-making.

Given her historic expertise, China has in its nationwide psyche an impulse by no means to turn out to be ‘the sick man of the East’ once more. Today, China’s willingness to co-operate with worldwide our bodies emanates out of reputational considerations somewhat than technical-medical concerns.

This was clearly manifested in her dealing with of two epidemics lately: the Severe Acute Respiratory Syndrome (SARS) and HIV/AIDS episodes. This paper concludes that China’s nationalism performs an inhibiting function in China’s makes an attempt to additional incorporate herself into the structure of world well being governance in the long term.

Chilean laws on metal-polluted soils: The must advance from adapting overseas legal guidelines in direction of growing sovereign laws.

Chile as a significant worldwide Cu producer faces severe soil contamination points in mining areas. Currently Chile doesn’t have any particular legislation governing the utmost permissible concentrations of metals in soils to guard ecosystems and human well being. Chile closely depends on the usage of environmental legal guidelines of 14 overseas international locations; the selection of the nation will depend on the similarity of its environmental circumstances with these in Chile.

In this research, we used an internet database to match the similarity of Chilean rocks to these in overseas international locations. Likewise, we carried out soil sampling and decided the background concentrations of Cu, As, Pb, and Zn in soils of the Aconcagua basin, the most important river basin within the Valparaiso Region of central Chile.

The outcomes confirmed that geochemical patterns in Chile have the best resemblance to New Zealand, Mexico, and Italy. The background Cu focus within the Aconcagua basin (134 mg kg-1) exceeded the legislated limits of New Zealand (100 mg kg-1) and Italy (120 mg kg-1), whereas the background Zn focus (200 mg kg-1) exceeded the legislated restrict of Italy (150 mg kg-1).

Due to the elevated pure abundance of Cu and Zn in Chile, worldwide legal guidelines shouldn’t be utilized in Chile for the evaluation of soil contamination. In addition, we assessed ecological threat utilizing the outcomes of our earlier research obtained by analyzing native field-contaminated soils of the Valparaiso area.

In the Aconcagua basin, Cu posed excessive threat for vegetation in 11% of the samples, whereas As posed excessive threat for earthworms in 48% of the samples. We counsel that future research are required to seek for different organisms that may function biomarkers of steel toxicity as a result of our earlier research had been restricted to vegetation and earthworms. Importantly, As posed excessive threat to human well being in 25% of the samples in our research.

There is a necessity for future research to exhibit empirically an affiliation between soil As and kids’s blood As as a way to set up the nationwide threshold values of soil As to guard human well being. We conclude that there’s an pressing want in Chile to advance from the present method of adapting overseas legal guidelines to growing Chilean sovereign environmental laws.
