Constitutional Validity of Implementation of Mandal Commission Recommendations
No full textThe author argues that the Government action on the Mandal Commission is constitutionally valid. It does not in any way violate any of the Fundamental Rights let alone Articles 14, 15 and 16. However, the author concedes, considering the volatile situation at hand and the instability writ large in the political scenario, it is difficult to be certain as to how the Supreme Court will react. The author maintains that it is possible to uphold the Mandal Commission government action by focusing on the Supreme Court’s interpretation of Articles 14, 15 and 16 as three provisions form part of one code, each embodying a different facet of the guarantee of equality.

Correlations between meteorological parameters and prostate cancer
No full textAbstract Background There exists a north-south pattern to the distribution of prostate cancer in the U.S., with the north having higher rates than the south. The current hypothesis for the spatial pattern of this disease is low vitamin D levels in individuals living at northerly latitudes; however, this explanation only partially explains the spatial distribution in the incidence of this cancer. Using a U.S. county-level ecological study design, we provide evidence that other meteorological parameters further explain the variation in prostate cancer across the U.S. Results In general, the colder the temperature and the drier the climate in a county, the higher the incidence of prostate cancer, even after controlling for shortwave radiation, age, race, snowfall, premature mortality from heart disease, unemployment rate, and pesticide use. Further, in counties with high average annual snowfall (>75 cm/yr) the amount of land used to grow crops (a proxy for pesticide use) was positively correlated with the incidence of prostate cancer. Conclusion The trends found in this USA study suggest prostate cancer may be partially correlated with meteorological factors. The patterns observed were consistent with what we would expect given the effects of climate on the deposition, absorption, and degradation of persistent organic pollutants including pesticides. Some of these pollutants are known endocrine disruptors and have been associated with prostate cancer.</p
Jane Austen and the popular novel: the determined author
No full textJane Austen and the Popular Novel: The Determined Author offers a provocative reinterpretation of one of the most cherished authors in the English literary canon. Austen criticism has traditionally fixed her oeuvre within the ideological locus of the 1790s, ignoring the more topical elements displayed by her novels. Such accounts have consequently neglected the complex interactions that took place between Austen's works and newer forms of popular fiction, such as the Evangelical tale, the national romance, and historical novel. By situating Austen in the 1810s - the immediate literary period within which she published - this book argues for the inherently intertextual nature of her novels, positing that her 'innovation' lies not in her uniqueness, but in her polyvalent negotiations with other literary models. Jane Austen and the Popular Novel demonstrates the extent to which Austen was not only a determined author, but also an author determined by the literary marketplace itself
Supporting Data for “Why So Slow? Mechanistic Insights from Studies of a Poor Catalyst for Polymerization of ε-Caprolactone”
No full textThese files contain data along with associated output from instrumentation supporting all results reported in Stasiw, D. E.; Mandal, M.; Neisen, B. D.; Mitchell, L. A.; Cramer, C. J.; Tolman, W. B. Why so slow? Mechanistic insights from studies of a poor catalyst for polymerization of ε-caprolactone. Inorg. Chem., 2016, 56, 725–728. Polymerization of ε-caprolactone (CL) using an aluminum alkoxide catalyst (1) designed to prevent unproductive trans binding was monitored at 110 °C in toluene-d8 by 1H NMR and the concentration versus time data fit to a first-order rate expression. A comparison of t1/2 for 1 to values for many other aluminum alkyl and alkoxide complexes shows much lower activity of 1 toward polymerization of CL. Density functional theory calculations were used to understand the basis for the slow kinetics. The optimized geometry of the ligand framework of 1 was found indeed to make CL trans binding difficult: no trans-bound intermediate could be identified as a local minimum. Nor were local minima for cis-bound precomplexes found, suggesting a concerted coordination–insertion for polymer initiation and propagation. The sluggish performance of 1 is attributed to a high-framework distortion energy required to deform the “resting” ligand geometry to that providing optimal catalysis in the corresponding transition-state structure geometry, thus suggesting a need to incorporate ligand flexibility in the design of efficient polymerization catalysts..

Zero Energy States for Commensurate Hopping Modulation of a Generalized Su-Schrieffer-Heeger Chain in the Presence of a Domain Wall
No full textWe study the effect of domain wall (DW) on zero-energy states (ZESs) in the Su-Schrieffer-Heeger (SSH) chain. The chain features two fractional ZESs in the presence of such DW, one of which is localized at the edge and the other bound at the location of DW. This zero-energy DW state exhibits interesting modifications when hopping modulation is tuned periodically. We studied the energy spectra for commensurate frequencies and . Following the recent study by the author of this paper [S. Mandal, S. Kar, Phys. Rev. B 109, 195124 (2024)], we showed numerically, along with physical intuition, that one ZES can bound at the DW position only for commensurate frequency for zero or an integer values, while for with nonzero or an integer value they appear only at the edges of the chain. We verify our numerical results by using exact analytical techniques. Both analyses indicate the realization of the Jackiw-Rebbi modes for our model only with . Moreover, the localization of zero-energy edge and DW states are investigated which reveals their localized (extended) nature for smaller (larger) (amplitude of DW). The localization of topological DW states is suppressed as the width of DW () increases (typically scaled as ) while the edge state shows an extended behavior only for the large limit.10 pages, 9 figure

Are you sitting comfortably? The political economy of the body
No full textThe aim of this paper is to examine the relationship between the mass production of furniture in modern industrial societies and lower back pain (LBP). The latter has proven to be a major cost to health services and private industry throughout the industrialised world and now represents a global health issue as recent WHO reports on obesity and LBP reveal. Thus far there have been few co-ordinated attempts to deal with the causes of the problem through public policy. Drawing upon a range of sources in anthropology, health studies, politics and economics, the paper argues that this a modern social problem rooted in the contingent conjuncture of natural and social causal mechanisms. The key question it raises is: what are the appropriate mechanisms for addressing this problem? This paper develops an analysis rooted in libertarian social theory and argues that both the state and the capitalist market are flawed mechanisms for resolving this problem. There remains a fundamental dilemma for libertarians, however. Whilst the state and the market may well be flawed mechanisms, they are the dominant ones shaping global political economy. To what extent can libertarians work within these structures and remain committed to libertarian goals
