Bias In Favour Research Articles

Shaping Sports Consciousness in the Early Years of Israeli Statehood

The Encyclopedia of Sports and Body Culture was published in Israel in 1959. The authors were prominent members of Hapoel, a sports club established by the Histadrut labour federation. The Encyclopedia was not merely a compendium of knowledge and a handbook of ‘dos and don’ts’ in the field of sports, but a secular ‘code of law’—a veritable manual for daily living. This article explores the circumstances surrounding the volume's publication and traces its roots and its contribution to Israeli body culture. The Encyclopedia’s authors aimed to assemble a treasury of information on sports and body culture that would seep into collective consciousness and shape the country's historic narrative in this sphere. Owing to its canonical nature, the Encyclopedia became a political tool in the struggle between Hapoel and Maccabi, which represented rival social sectors - the workers and the middle-class. The Encyclopedia was criticized for its alleged bias in favour the workers' movement and its alleged complicity in promoting the hegemony of Hapoel in Israeli sports by playing down the role of other sports organizations. Despite the criticism, the book was very successful and is used as a basic textbook on Israeli sports and physical culture to this day.

The Right to Know and not to Know: Predictive Genetic Diagnosis and Non-diagnosis.

The expansion of genetic diagnostic potential in the direction of future contingencies (risks) creates temptations and compulsions for timely knowledge and responsible-sometimes radical-prevention. In the area of mamma carcinoma, the 'Angelina Jolie effect' has not only been a media topic but has had real consequences. The undisputed right to knowledge is increasingly taking on the character of a general recommendation or even norm for society as a whole, regardless of the possibly toxic consequences of discovering a predisposition. In an "enlightened knowledge society" in which health and illness increasingly "appear as products of our own actions" (Giovanni Maio), not wanting to know is difficult; thus, it is all the more significant that this concept has found widespread recognition in current law. Its legal practical implementation, however, presents several questions that have not yet been fully clarified, for example in connection with incidental medical findings or family members affected as third parties. It is also unclear how, in the age of next-generation sequencing and the standardizing digitalization of medicine and society, it will be possible to counteract the cultural bias in favour of knowledge, even outside the law.

Minimum Support Prices in India: Distilling the facts

In recent years, the Minimum Support Price (MSP) and government procurement especially of paddy and wheat have been discussed widely, but these discussions have often drawn on evidence that is dated and incomplete. Consequently, such discussions have clouded the facts, resulting in a large number of factoids. According to these popular beliefs, very few farmers benefit (6% only), only large farmers benefit, and only farmers of Punjab and Haryana (and to some extent western Uttar Pradesh) benefit. In this article, we examine these three factoids and draw on multiple data sources to distil the facts. We argue that existing evidence suggests a more complex picture –(1) the MSP impacts 13(16)% paddy(wheat) sellers; (2)the geographies of procurement have expanded to new states including notably, Madhya Pradesh, Chhattisgarh and Odisha, and (3) Although, at the national level, there is a large farmer bias, this doesn’t imply exclusion of small and marginal farmers. In fact, majority of the beneficiaries are marginal and small farmers on both the extensive and the intensive margins. Further, we find substantial heterogeneity by states. Haryana for instance has a bias in favour of small and marginal farmers. We conclude that debates on the MSP and procurement must therefore take into account the changed geography of procurement and the profile of sellers and recognize the diversity of experiences with procurement across states.

Ensemble-based model selection for imbalanced data to investigate the contributing factors to multiple fatality road crashes in Ghana

The study aims to identify relevant variables to improve the prediction performance of the crash injury severity (CIS) classification model. Unfortunately, the CIS database is invariably characterized by the class imbalance. For instance, the samples of multiple fatal injury (MFI) severity class are typically rare as opposed to other classes. The imbalance phenomenon may introduce a prediction bias in favour of the majority class and affect the quality of the learning algorithm. The paper proposes an ensemble-based variable ranking scheme that incorporates the data resampling. At the data pre-processing level, majority weighted minority oversampling (MWMOTE) is employed to treat the imbalanced training data. Ensemble of classifiers induced from the balanced data is used to evaluate and rank the individual variables according to their importance to the injury severity prediction. The relevant variables selected are then applied to the balanced data to form a training set for the CIS classification modelling. An empirical comparison is conducted through considering the variable ranking by: 1) the learning of single inductive algorithm with imbalanced data where the relevant variables are applied to the imbalanced data to form the training data; 2) the learning of single inductive algorithm with MWMOTE data and the relevant variables identified are applied to the balanced data to form the training data; and 3) the learning of ensembles with imbalanced data where the relevant variables identified are applied to the imbalanced data to form the training data. Bayesian Networks (BNs) classifiers are then developed for each ranking method, where nested subsets of the top ranked variables are adopted. The model predictions are captured in four performance indicators in the comparative study. Based on three-year (2014–2016) crash data in Ghana, the empirical results show that the proposed method is effective to identify the most prolific predictors of the CIS level. Finally, based on the inference results of BNs developed on the best subset, the study offers the most probable explanations to the occurrence of MFI crashes in Ghana.

Fundamental Rights and Democratic Sovereignty in the EU: The Role of the Charter of Fundamental Rights of the EU (CFREU) in Regulating the European Social Market Economy

Abstract The EU, in its present configuration, has often been accused of a persistent and deep structural bias in favour of economic integration to the detriment of the democratic and social values of its Member States. In response to that accusation, can the Charter of Fundamental Rights of the EU (CFREU) come to the rescue and be mobilized, ultimately before a judicially-activist Court of Justice of the EU (CJEU), as a vehicle of social justice, in an effort to correct bias and to counter-balance the expansive economic liberties of the European single market? Exploring this question is a timely topic given a clearly discernable new constitutional turn in the jurisprudence of the CJEU’s Grand Chamber, especially now under the current presidency of Koen Lenaerts. The ‘Lenaerts-Court’, as this article will argue, has embarked on a new EU fundamental-rights jurisprudence, visibly aimed at strengthening the dignitarian-social dimension of EU integration and at adding flesh to the bones of the commitment to a European social market economy in Article 3(3) of the Treaty of European Union (TEU). Yet proposals in support of greater reliance on the substantive, but open-textured, provisions of the CFREU, in the pursuit of a ‘fair balance’ between the EU’s economic and dignitarian-social dimensions, immediately run into democratic-minded concerns about sovereignty passing from the Member States to the courts, and ultimately to the CJEU itself. The persistent worry is that democratic sovereignty over constitutionally sensitive—but morally and politically divisive—choices is being turned into a ‘sovereignty of law’—in ways that not only risk foreclosure of democratic debate over yet unsettled key societal matters but gives up democratic legitimation as a central element of modern constitutionalism (‘over-constitutionalisation’, Dieter Grimm). Thus, the CJEU is being simultaneously criticized for its alleged economic bias and for its efforts to overcome that bias. In an effort to address—and disarm—this democratic-minded concern, this article argues that judicial emphasis on the CFREU’s dignitarian-social values need not per se lead to the consequence of over-constitutionalisation. Rather, this article proposes to look at the Grand Chamber’s new fundamental-rights jurisprudence in the single-market context as creating a framework for plural and inclusive democratic deliberation on key societal choices and values. To that end, the article proposes a new reading of the Grand Chamber’s jurisprudence on the efficacy of fundamental rights in the economic sphere and, in particular, on the horizontal direct effect of CFREU rights.

The Trade (Policy) Discourse in Top Economics Journals

ABSTRACT In the aftermath of recent populist upheavals in Europe, nationalist economic policies challenge the overly positive view on economic integration and the reduction of trade barriers established by standard economic theory. For quite a long time the great majority of economists supported trade liberalisation policies, at least those actively engaged in policy advice or public debates. In this paper, we examine the elite economics discourse on trade policies during the last 20 years regarding specific characteristics of authors, affiliations, citation patterns, the overall attitude towards trade, as well as the methodological approach applied in these papers. Our analysis yields the following results: First, the hierarchical structure of economics also manifests in the debate about trade. Second, while we found some indications of a shift towards more empirically oriented work, quite often empirical data is solely used to calibrate models rather than to challenge potentially biased theoretical assumptions. Third, top economic discourses on trade are predominantly characterised by a normative bias in favour of trade-liberalisation-policies. Forth, we found that other-than-economic impacts and implications of trade policies (political, social and cultural as well as environmental issues) to a great extent either remain unmentioned or are rationalised by means of pure economic criteria.

EU agencies’ stakeholder bodies: vehicles of enhanced control, legitimacy or bias?

ABSTRACT EU agencies are increasingly subject to a flurry of stakeholder bodies. Despite their prevalence, and the considerable variation in structures formally professed to serve the same purpose, we know little about the actor preferences driving the set-up of such structures or the potential implications of specific institutional design choices. We systematically map structural variations across EU agencies and analyse to what extent the establishment and the design of stakeholder bodies is principal-imposed or agency-initiated. Do stakeholder structures enhance political control serving to broadly legitimise agencies, or to the contrary, do they reflect preferences of the bureaucratic actors they are meant to control, and with what implications? We find that, for the most part, weak principal control and steering leaves it to the agencies themselves to design stakeholder bodies as they see fit. This has the potential to introduce unsanctioned biases in favour of specific groups, potentially depleting rather than bolstering legitimacy. A major implication of EU agencies’ stakeholder engagement is that the agency model is currently in flux, moving away from the classic insulated agency towards greater politicization in regulatory policy.

How are nature-based solutions contributing to priority societal challenges surrounding human well-being in the United Kingdom: a systematic map

BackgroundThe concept of nature-based solutions (NBS) has evolved as an umbrella concept to describe approaches to learning from and using nature to create sustainable socio-ecological systems. Furthermore, NBS often address multiple societal challenges that humans are facing in the medium to long-term and as such can enhance human well-being (HWB). This study was commissioned to fulfil the need for a targeted systematic evidence map on the linkage between NBS and HWB to support focused research going forward that addresses the key knowledge needs of policy makers in the UK and beyond.MethodsA consultation with policy makers and government agency staff (n = 46), in the four component parts of the UK (England, Wales, Scotland, Northern Ireland) was conducted in spring 2019. This identified four key societal challenges of operational experience lacking a scientific evidence base. Three of these challenges related to management issues: NBS cost-efficacy, governance in planning, environmental justice. The fourth challenge related to the acoustic environment (soundscape). Using systematic methods, this study searched for and identified studies that assessed NBS on HWB with regard to these four selected societal challenges.Review findingsA total of 7287 articles were returned from the systematic search and screened for suitability at the level of title and abstract. A total of 610 articles passed screening criteria to warrant full text screening. Of these, 115 studies met the full text criteria for eligibility in the final systematic map database. Included studies were coded for twelve NBS interventions and ten HWB related outcome categories. Most of the evidence reviewed referred to natural, blue or green infrastructure in the urban environment and focused on economic, material and health aspects of HWB. Less than 2% of studies identified in the searches robustly reported the role of NBS actions or interventions on HWB compared with non-NBS actions or interventionsConclusionThis systematic map found the evidence base is growing on NBS-HWB linkages, but significant biases persist in the existing literature. There was a bias in favour of the urban environment and restoration studies focused on conservation aspects, with only a few studies investigating the full suite of advantages to HWB that can be delivered from NBS actions and interventions. The soundscape was the least studied of the societal challenges identified as being of key importance by policy makers, with cost-efficiency the most reported. There was a lack of robust long-term studies to clearly test the potential of NBS regarding the HWB outcomes compared with non-NBS alternatives. This lack of robust primary knowledge, covering all four key societal challenges identified, confirms that the knowledge gaps identified by the policy makers persist, and highlights a clear research need for long-term, transdisciplinary studies that focus on comparisons between NBS and non-NBS alternatives

DOES INVESTOR PROTECTION INCREASE FOREIGN DIRECT INVESTMENT? A META‐ANALYSIS

AbstractWe undertake a meta‐analysis of the effects of international investment agreements for the protection of foreign investors on foreign direct investment using 2107 estimates drawn from 74 studies. Our meta‐analysis finds robust evidence that effect of international investment agreements is so small as to be considered zero. However, our results do not rule out the possibility that the effect of these agreements is, in fact, positive and that current research methods are insufficiently powerful or precise to identify the underlying genuine effect. FDI from developed countries appears to be more responsive to the existence of investment protection, and there is evidence of publication–selection bias in favour of studies that find a positive effect for investor protection.

Carving Out an Empire? How China Strategically Uses Aid to Facilitate Chinese Business Expansion in Africa **

Abstract:China’s rising investment and aid flows into Africa have raised concerns over its increasing influence, triggering worries about a new scramble for Africa. This paper sorts out the motivations behind the various forms of Chinese aid, arguing that China uses different types of aid strategically to divert the recipient countries’ economic and institutional orientation towards its own interests. Exploiting the AidData set, we show that China’s official development aid (ODA) is positively related to an export bias in favour of China, suggesting that it serves to secure privileged access for Chinese firms to African resources. ODA tends to flow to less democratic regimes, because less accountable governments have more power to offer long-run privileges to their financial supporters. In contrast, we show that other official flows (OOF) are used to increase China’s import share and is positively related to institutional quality, since this has a positive influence on market growth. This suggests that OOF is mainly used to facilitate Chinese access to promising African consumer markets. We conclude that while China employs different aid flows for different economic purposes, it uses all aid flows strategically to advance its interests and create an economic sphere of influence in Africa.

Double-peak emission line galaxies in the SDSS catalogue

Double-peak narrow emission line galaxies have been studied extensively in the past years, in the hope of discovering late stages of mergers. It is difficult to disentangle this phenomenon from disc rotations and gas outflows with the sole spectroscopic measurement of the central 3″. We aim to properly detect such galaxies and distinguish the underlying mechanisms with a detailed analysis of the host-galaxy properties and their kinematics. Relying on the Reference Catalogue of Spectral Energy Distribution, we developed an automated selection procedure and found 5663 double-peak emission line galaxies at z < 0.34 corresponding to 0.8% of the parent database. To characterise these galaxies, we built a single-peak no-bias control sample (NBCS) with the same redshift and stellar mass distributions as the double-peak sample (DPS). These two samples are indeed very similar in terms of absolute magnitude, [OIII] luminosity, colour-colour diagrams, age and specific star formation rate, metallicity, and environment. We find an important excess of S0 galaxies in the DPS, not observed in the NBCS, which cannot be accounted for by the environment, as most of these galaxies are isolated or in poor groups. Similarly, we find a relative deficit of pure discs in the DPS late-type galaxies, which are preferentially of Sa type. In parallel, we observe a systematic central excess of star formation and extinction for double peak (DP) galaxies. Finally, there are noticeable differences in the kinematics: The gas velocity dispersion is correlated with the galaxy inclination in the NBCS, whereas this relation does not hold for the DPS. Furthermore, the DP galaxies show larger stellar velocity dispersions and they deviate from the Tully-Fisher relation for both late-type and S0 galaxies. These discrepancies can be reconciled if one considers the two peaks as two different components. Considering the morphological biases in favour of bulge-dominated galaxies and the star formation central enhancement, we suggest a scenario of multiple, sequential minor mergers driving the increase of the bulge size, leading to larger fractions of S0 galaxies and a deficit of pure disc galaxies.

Whether your name is Manuel or María matters: gender biases in recommendations to study engineering

ABSTRACT A controlled experiment was conducted to detect gender biases that participants, acting as advisers, may have when providing guidance to teenagers on their career choice. We presented a fictional profile to the study participants – university students from Spain – of a 15-year-old person, called Manuel or María, with two possible levels of academic record. The participants were asked to evaluate the student’s mathematical ability and provide guidance regarding whether or not he or she should study engineering in the future. We assumed that the effect of being a male target on the recommendation to study engineering is partially mediated by the fact that the participants attribute a greater mathematical ability to males. Our results suggest that a significant degree of gender bias in favour of males persists in the recommendation to study engineering. We propose some practical implications for advisers and for equality policies.

Auditory processing in the zebra finch midbrain: single unit responses and effect of rearing experience.

In birds the auditory system plays a key role in providing the sensory input used to discriminate between conspecific and heterospecific vocal signals. In those species that are known to learn their vocalizations, for example, songbirds, it is generally considered that this ability arises and is manifest in the forebrain, although there is no a priori reason why brainstem components of the auditory system could not also play an important part. To test this assumption, we used groups of normal reared and cross-fostered zebra finches that had previously been shown in behavioural experiments to reduce their preference for conspecific songs subsequent to cross fostering experience with Bengalese finches, a related species with a distinctly different song. The question we asked, therefore, is whether this experiential change also changes the bias in favour of conspecific song displayed by auditory midbrain units of normally raised zebra finches. By recording the responses of single units in MLd to a variety of zebra finch and Bengalese finch songs in both normally reared and cross-fostered zebra finches, we provide a positive answer to this question. That is, the difference in response to conspecific and heterospecific songs seen in normal reared zebra finches is reduced following cross-fostering. In birds the virtual absence of mammalian-like cortical projections upon auditory brainstem nuclei argues against the interpretation that MLd units change, as observed in the present experiments, as a result of top-down influences on sensory processing. Instead, it appears that MLd units can be influenced significantly by sensory inputs arising directly from a change in auditory experience during development.

Oxide Edge Trap Density Extraction in Silicon Nanowire MOSFET From Tunnel Current Noise Measurement in Gated Diode Like Arrangement

Edge traps in the gate oxide of silicon nanowire MOSFETs have been extracted from tunnel current noise measurement in a gated diode like arrangement. We have found that, low frequency noise in tunnel current results from collective response of the edge traps available within the gate oxide surrounding band-to-band generation (BTBG) region of silicon nanowire, and when the BTBG region is accessed by favorable terminal biases. From detail modeling of the phenomenon, we derived a closed form expression of the tunneling current noise power spectral density (PSD) employing which oxide edge trap density in nanowire MOSFET had been extracted through its fit with the experimental noise PSD data. We furthermore validated our model for different BTBG biases, and contrasted our result with the bulk oxide trap density in identical MOSFET, while the latter was separately estimated from the gate current noise PSD measurement. Mismatch between the oxide bulk trap and edge trap concentrations has been found, whereby actual edge trap density remains otherwise hidden from the widely employed gate current noise measurement technique. It is because, the present scheme improves the resolution of the extracted oxide edge trap concentration in surrounded gate MOSFET owing to constricted tunnel current flow near the corner of the gate which imposes selectivity on the oxide edge traps

Navo Minority Over-sampling Technique (NMOTe): A Consistent Performance Booster on Imbalanced Datasets

Imbalanced data refers to a problem in machine learning where there exists unequal distribution of instances for each classes. Performing a classification task on such data can often turn bias in favour of the majority class. The bias gets multiplied in cases of high dimensional data. To settle this problem, there exists many real-world data mining techniques like over-sampling and under-sampling, which can reduce the Data Imbalance. Synthetic Minority Oversampling Technique (SMOTe) provided one such state-of-the-art and popular solution to tackle class imbalancing, even on high-dimensional data platform. In this work, a novel and consistent oversampling algorithm has been proposed that can further enhance the performance of classification, especially on binary imbalanced datasets. It has been named as NMOTe (Navo Minority Oversampling Technique), an upgraded and superior alternative to the existing techniques. A critical analysis and comprehensive overview on the literature has been done to get a deeper insight into the problem statements and nurturing the need to obtain the most optimal solution. The performance of NMOTe on some standard datasets has been established in this work to get a statistical understanding on why it has edged the existing state-of-the-art to become the most robust technique for solving the two-class data imbalance problem.

Electrophysiology's Identity Crisis: What our Clinical Trials Do and Do Not Say About Us.

Although it has not always been this way, the impact of large, randomised clinical trials in electrophysiology is limited, at least compared with other disciplines in cardiology. This has been particularly true regarding procedural aspects of our field: successful randomised trials are rare and observational trials are small and typically without a proper active control group. In this article, the authors examine the reasons behind this circumstance, which include underinvestment from funding sources; lack of consensus on procedural endpoints; lack of consensus on techniques; and a therapeutic bias in favour of procedural intervention that stands in the way of investigator equipoise. Together, these factors have created a scientific culture dominated by small-scale, siloed, observational research and unwillingness to collaboratively advance the field with consensus and prospective trials. The authors feel that it is increasingly urgent to improve the scientific basis for clinical practice and explore strategies to accomplish this goal.

The impact of light polarization effects on weak lensing systematics

ABSTRACT A fraction of the light observed from edge-on disc galaxies is polarized due to two physical effects: selective extinction by dust grains aligned with the magnetic field and scattering of the anisotropic starlight field. Since the reflection and transmission coefficients of the reflecting and refracting surfaces in an optical system depend on the polarization of incoming rays, this optical polarization produces both (a) a selection bias in favour of galaxies with specific orientations and (b) a polarization-dependent point spread function (PSF). In this work, we build toy models to obtain for the first time an estimate for the impact of polarization on PSF shapes and the impact of the selection bias due to the polarization effect on the measurement of the ellipticity used in shear measurements. In particular, we are interested in determining if this effect will be significant for Wide-Field Infrared Survey Telescope (WFIRST). We show that the systematic uncertainties in the ellipticity components are 8 × 10−5 and 1.1 × 10−4 due to the selection bias and PSF errors respectively. Compared to the overall requirements on knowledge of the WFIRST PSF ellipticity (4.7 × 10−4 per component), both of these systematic uncertainties are sufficiently close to the WFIRST tolerance level that more detailed studies of the polarization effects or more stringent requirements on polarization-sensitive instrumentation for WFIRST are required.

Brain death in early pregnancy: A legal and ethical challenge coming to your intensive care unit?

Increasingly, reports are emerging of maternal physiological support after brain death in pregnant women declared brain dead long before the gestational age of foetal viability. While these 'miracle babies' often receive significant media attention - such as the recent case of Catarina Sequeira - it is difficult to estimate the probability of a live birth in such circumstances given a clear publication bias in favour of reporting good outcomes. In a number of highly publicised cases, continuation of maternal physiological support after brain death has been attempted against the express wishes of the patient's family in jurisdictions where a foetal right to life is given weight in law. The legal issues around discontinuation of maternal physiological support after brain death have not yet been assessed by a UK court. The scenario is easily envisioned, however, where conflict emerges as to the appropriateness of such support. While there is no statutory definition of death in the UK, the courts have accepted brain-dead patients as legally dead upon completion of brainstem testing. However, as UK law grants few explicit legal rights to a foetus, it is unclear as to how conflicts are to be resolved. This article is not intended as a systematic review of the medical or legal academic literature, nor as a review of the clinical management of the pregnant brain-dead patient; rather, it aims to summarise the evidence base for maternal physiological support after brain death and the relevant case law. Using a recent case as an example, this article will outline the legal approach to death in the UK, contrast the status in law of a brain-dead mother and her foetus, and advance an argument of the circumstances in which maternal physiological support after brain death may be ethically justifiable. The authors hope this will assist the UK intensivist in the complex decision-making such cases demand.
