 Strategic Responses in Language Use and Ethnolinguistic Reasoning to Changing Socio-Ecologies: Insights from the Yucatec Maya
 28 July 2021 Cecilia Padilla-Iglesias
 University of Zurich Language is the human universal mode of communication, and is dynamic and constantly in flux to accommodate user needs as individuals interface with the changing world around them. However, we know surprisingly little about how language users respond to rapidly changing socio-ecological landscapes, both now and throughout our evolutionary history. In this talk, I will discuss to what extent humans can strategically adapt the way they use, transmit and even reason about language and linguistic identities in ways that are useful in dynamic environments. I will present longitudinal work from Yucatec Mayan communities throughout a period comprising the transition to a market economy and increased contact with Spanish-speaking towns. I will provide evidence that our flexible developmental processes allow us to use languages as tools for responding adaptively to social information around us. By exploring the ways in which we do so, I will discuss the possibility of predicting the circumstances under which indigenous language use may be sustained and equally those under which it might be at risk when coming into contact with majority languages.

description: A practical experimental scheme for a quantum simulator of strongly correlated electrons is proposed. Our scheme employs electrons confined in a two dimensional electron gas in a GaAs/AlGaAs heterojunction. Two surface acoustic waves are then induced in the GaAs substrate, which create a two dimensional ``egg-carton'' potential. The dynamics of the electrons in this potential is described by a Hubbard model with long-range Coulomb interactions. The state of the electrons in this system can be probed via its conductance and noise properties. This allows the identification of a metallic or insulating state. Numerical estimates for the parameters appearing in the effective Hubbard model are calculated using the proposed experimental system. These calculations suggest that observations of quantum phase transition phenomena of the electrons in the potential array are within experimental reach.

Je n’attends pas votre réponse, mon cher ami, pour vous dire que notre ami la Condamine, dont je viens de recevoir une lettre de 6 pages indéchiffrables, sera enchanté de vous voir à Paris si vous voulez faire le voyage avec moi. Voilà un motif de plus pour vous engager davantage. Nous logerons si vous voulez à la maison de Saint-Charles, chez les pères doctrinaires, et quelques-uns de ceux que vous connaissez à Nîmes vous donneront bien une lettre de recommandation pour le supérieur. Vous avez l’avantage d’être à portée du jardin du roi, et nous connaîtrons M. de Buffon qui sûrement nous sera honnête. Si vous m’objectez votre rhumatisme, je vous répondrai que nous n’avons qu’à partir dans le carême et qu’en cas de[de crise] je vous servirai. Mlle votre sœurpeut bien se passer quelques mois de vous, et votre bâtiment n’aura plus besoin de votre présence. Quant à la dépense, elle ne peut être forte si nous prenons un domestique à nous deux, il ne s’agira tout au plus que de deux louis par tête pour les fiacres de pure nécessité et la pension sera bornée. Je vous avoue que je m’estimerais l’homme du monde le plus heureux de faire ce voyage avec vous, parce que je verrais avec vos yeux n’ayant presque rien vu, quoique j’ai souvent été à Paris. Il serait tout simple de venir à Maruège, je vous enverrai prendre à Florac, vous vous reposeriez chez moi, et nous partirions gaiement à la garde de Dieu. Voyez mon cher ami si cela vous arrange et ne m’affligez pas par un refus.
Je vous embrasse de tout mon cœur.

Labarthe.

Je pars dans deux jours pour Maruège où j’attendrai votre réponse.

Marginally Trapped Surfaces and AdS/CFT

description: It has been proposed that the areas of marginally trapped or anti-trapped surfaces (also known as leaves of holographic screens) may encode some notion of entropy. To connect this to AdS/CFT, we study the case of marginally trapped surfaces anchored to an AdS boundary. We establish that such boundary-anchored leaves lie between the causal and extremal surfaces defined by the anchor and that they have area bounded below by that of the minimal extremal surface. This suggests that the area of any leaf represents a coarse-grained von Neumann entropy for the associated region of the dual CFT. We further demonstrate that the leading area-divergence of a boundary-anchored marginally trapped surface agrees with that for the associated extremal surface, though subleading divergences generally differ. Finally, we generalize an argument of Bousso and Engelhardt to show that holographic screens with all leaves anchored to the same boundary set have leaf-areas that increase monotonically along the screen, and we describe a construction through which this monotonicity can take the more standard form of requiring entropy to increase with boundary time. This construction is related to what one might call future causal holographic information, which in such cases also provides an upper bound on the area of the associated leaves.

Bureaucratic corruption and market access : the case of smallholder farmers in Nigeria

description: This thesis addresses the question of how bureaucratic corruption affects the market access of smallholder farmers in Nigeria. In this context, two sub-questions investigated where such corruption occurs and what transmission mechanisms can be observed. To answer these questions, 12 expert interviews were conducted and analysed using the qualitative content structuring of Mayring. This material was supplemented with current research, and theoretical foundations of principal agent and transaction cost theory. The results indicate a strong negative effect of corruption on market access, either directly or indirectly. It affects the resource base and technology of smallholder farmers due to their dependency on government services, where corruption results in unequal treatment, the resale of resources at market prices and negative consequences for the quality, availability and access to services. Unequal treatment in the public service provision and moribund institutional settings, particularly in terms of road infrastructure, contribute to skewed power relations between smallholders, their competitors and market intermediaries resulting in a strong impediment for market functionality. Particularly the smallholders’ competitors use corrupt payments to gain advantages, while smallholders are deprived by corruption from a variety of opportunities. Market functionality is further impaired by extortionary practices on markets contributing to the deterring nature of such payments, which also occur in formalisation procedures and during transportation and heavily constrain the smallholders' market orientation. Relevant corrupt practices occur in governmental offices, banks, distribution centres as well as on farms, markets and roads. The transmission mechanisms where found to include three levels. The strategic or policy formation level, the operational or implementation level as well as the tactical level, which include personal interactions with bureaucrats. The former usually result either in lost opportunities or even detrimental effects on farmers, while the latter generates costs aggravated by power imbalances between extortionist and smallholder farmer.
Thermal conductivity of Al-doped MgB2: Impurity scattering and the validity of the Wiedemann-Franz law

description: We report data on the thermal conductivity K(T,H) along the basal plane of the hexagonal crystal structure of superconducting Mg{1-y}Al{y}B2 with y=0.02 and 0.07 at temperatures between 0.5 and 50 K and in external magnetic fields between 0 and 70 kOe. The substitution of Al for Mg leads to a substantial reduction of the heat transport via electronic quasiparticles. The analysis of the K(T,H) data implies that the Al impurities provoke an enhancement of the intraband scattering rate, almost equal in magnitude for both the sigma- and the pi band of electronic excitations. This is in contrast with conclusions drawn from analogous data sets for material in which carbon replaces boron and where mainly the intraband scattering rate of the sigma band is enhanced. Our complete data set, including additional results of measurements of the low-temperature thermal conductivity of pure MgB2, confirms the validity of the Wiedemann-Franz law for both pure and doped MgB2.

description: Introduction: Living in the Appalachian Region of the United States (US) has been linked to poorer pediatric health outcomes as well as a lack of emergency department and hospital surge capacity during disasters. Purpose: We describe the characteristics of the Appalachian and non-Appalachian pediatric emergency networks in the US to determine if pediatric healthcare networks in Appalachia differ substantively from networks elsewhere in the US focusing on size, whether they were inter- or intra-state networks, and, most importantly, intensity of collaboration – factors impacting on pediatric disaster preparedness capabilities. Methods: Data were collected using a two-stage survey process. The first survey was used to identify networks. The second survey assessed the disaster preparedness capabilities and achievements of each identified network, the degree of fund sharing, and the intensity and formality of information sharing among network partners. Networks were separated into Appalachia or non-Appalachia networks based on state location. Results: Appalachian networks were more likely to be interstate and operating at the highest stage of network development compared to non-Appalachian networks, but were less likely to share funding among network partners. Implications: Despite consistently insufficient pediatric capacity, particularly for disasters, and repeated calls for collaboration among pediatric care providers, only three out of seventeen identified pediatric networks were operating in Appalachia. Operating in Appalachia was associated with less fund sharing, although Appalachian networks were more likely to have achieved the highest stage of network development. Developing new pediatric networks and increasing the intensity of collaboration (i.e., increased levels of fund sharing) among existing networks may improve network operations, collaboration, disaster preparedness, and health outcomes in Appalachian states.

description: The spin pumping mechanism and associated interfacial Gilbert damping are demonstrated in ion-beam sputtered Co2FeAl (CFA) /Mo bilayer thin films employing ferromagnetic resonance spectroscopy. The dependence of the net spin current transportation on Mo layer thickness, 0 to 10 nm, and the enhancement of the net effective Gilbert damping are reported. The experimental data has been analyzed using spin pumping theory in terms of spin current pumped through the ferromagnet /nonmagnetic metal interface to deduce the effective spin mixing conductance and the spin-diffusion length, which are estimated to be 1.16(0.19)x10^19 m^-2 and 3.50(0.35)nm, respectively. The damping constant is found to be 8.4(0.3)x10^-3 in the Mo(3.5nm) capped CFA(8nm) sample corresponding to a ~42% enhancement of the original Gilbert damping (6.0(0.3)x10^-3) in the uncapped CFA layer. This is further confirmed by inserting a Cu dusting layer which reduces the spin transport across the CFA /Mo interface. The Mo layer thickness dependent net spin current density is found to lie in the range of 1-3 MAm^-2, which also provides additional quantitative evidence of spin pumping in this bilayer thin film system.

description: This study of young children's collage in organised educational settings focuses specifically on collage as a symbolic activity. The research was conducted at two sites and involved 42 children aged between 3 and 5 years. The research was based on a contextual approach which acknowledged the multiple influences affecting the participants and the activity. I employed participant observation using microethnographic techniques to collect the data. This resulted in over 33 hours of video data and transcripts from the observation of children engaged in 411 collage activities. The study has provided evidence to suggest that young children employ collage symbolically in several forms, ranging from symbolic play to intentional symbolisation. Children's development in, and the effect of the social context on, their symbolic use of collage is considered. The ability of young children to engage in symbolic activity is influenced by their experience and play with collage materials, their facility with the tools, interaction with others, their intentions, and their realisation that the materials can stand for other entities. Symbolic activity is differentiated from representation in this context. This study offers a method by which to categorise collage symbolisation and to identify when children are engaged in symbolic activity in collage.
Gravity as a Constraint: A Quantum Saturation Approach for Cosmology and Black Holes
Creators: name: Welebny, Stefan Karl
Publisher: name: Zenodo
Year: 2025
Subjects: subject: Physical cosmology

description: We propose an interpretation of spacetime geometry based on a universal constraint on the quantum probability density. Rather than treating curvature as a response to energy-momentum, we interpret it as a regulatory adaptation of geometry to enforce a cap on quantum state concentration. By reducing a modified Einstein equation to depend solely on a saturation potential derived from a universal wave function, we explain black hole formation as local re-saturation and cosmic expansion as global desaturation. This framework replaces matter-driven curvature with an emergent geometric throttling of quantum evolution. The formulation connects black hole interiors, early-universe dynamics, and cosmic acceleration under one principle: regulation of quantum availability.

description: We present a preliminary analysis of the first high-resolution X-ray spectrum of a Seyfert 2 galaxy, Mkn 3, obtained with the High Energy Transmission Grating Spectrometer onboard the Chandra X-ray Observatory. The high-energy spectrum (lambda < 4 Ang) is dominated by reflection of the AGN continuum radiation in a cold optically thick medium and contains bright K-alpha fluorescent lines from iron and silicon, as well as weak, blended lines from sulfur and magnesium. The soft X-ray emission (4 < lambda < 23 Ang) is spatially extended along the [O III] ionization cone and shows discrete signatures of emission following recombination and photoexcitation produced in a warm photoionized region. The measured iron L line fluxes indicate that emission from collisionally ionized plasma is almost completely negligible, and does not contribute significantly to the total energy budget of the X-ray emission. We find that significant fractions of the H- and He-like resonance lines, as well as the observed iron L lines are produced through re-emission from the warm absorbing medium observed in Seyfert 1 galaxies. Its X-ray spectral properties are qualitatively consistent with those of a typical Seyfert 1 galaxy viewed at a different orientation, and provide further convincing evidence for the existence of an obscured Seyfert 1 nucleus in Mkn 3.

description: We compare the magnetic and electronic configuration of single Mn atoms in molecular beam epitaxy (MBE) grown Bi$_2$Se$_3$ thin films, focusing on electron paramagnetic (ferromagnetic) resonance (EPR and FMR, respectively) and superconducting quantum interference device (SQUID) techniques. X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) reveal the expected increase of disorder with increasing concentration of magnetic guest atoms, however, Kikuchi patterns show that disorder consists majorly of mum-scale 60deg twin domains in the hexagonal Bi$_2$Se$_3$ structure, which are promoted by the presence of single unclustered Mn impurities. Ferromagnetism below T$_C$ ~ (5.4 +/- 0.3) K can be well described by critical scaling laws M(T) ~ (1-T/T$_C$)$^β$ with a critical exponent $β$ = (0.34 +/- 0.2)), suggesting 3D Heisenberg class magnetism instead of e.g. 2D-type coupling between Mn-spins in van der Waals gap sites. From EPR hyperfine structure data we determine a Mn$^{2+}$ (d$^5$, S = 5/2) electronic configuration with a g-factor of 2.002 for -1/2 --> +1/2 transitions. In addition, from the strong dependence of the low temperature FMR fields and linewidth on the field strength and orientation with respect to the Bi$_2$Se$_3$ (0001) plane, we derive magnetic anisotropy energies of up to K1 = -3720 erg/cm3 in MBE-grown Mn-doped Bi$_2$Se$_3$, reflecting the first order magneto-crystalline anisotropy of an in-plane magnetic easy plane in a hexagonal (0001) crystal symmetry. Across the ferromagnetic-paramagnetic transition the FMR intensity is suppressed and resonance fields converge the paramagnetic limit of a Mn$^{2+}$ (d$^5$, S = 5/2).

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Variational principles for magnetohydrodynamics were introduced by previous authors both in Lagrangian and Eulerian form. In this paper we introduce simpler Eulerian variational principles from which all the relevant equations of barotropic magnetohydrodynamics can be derived. The variational principle is given in terms of six independent functions for non-stationary barotropic flows and three independent functions for stationary barotropic flows. This is less then the seven variables which appear in the standard equations of barotropic magnetohydrodynamics which are the magnetic field $\vec B$ the velocity field $\vec v$ and the density $ρ$. The equations obtained for non-stationary barotropic magnetohydrodynamics resemble the equations of Frenkel, Levich & Stilman \cite{FLS}. The connection between the Hamiltonian formalism introduced in \cite{FLS} and the present Lagrangian formalism (with Eulerian variables) will be discussed. Finally the relations between barotropic magnetohydrodynamics topological constants and the functions of the present formalism will be elucidated.

description: We develop a model for the infrared, optical and soft X-ray emission of the Crab pulsar in terms of anisotropic synchrotron emission by relativistic particles in an outer gap scenario with a single energy distribution. It is shown that such a distribution is naturally produced in an efficient pair cascade and that the energy of the primary particles are limited by synchrotron radiation. It is further shown that this synchrotron model is able to reproduce the spectral shape between the infrared and soft X-rays and also the corresponding luminosities. In particular, the long standing problem of the rapid spectral decline towards infrared frequencies is understandable as emission at very small pitch angles from low energy particles. Finally, we show that the scaling of our synchrotron model explains the observed correlation between the X-ray luminosity and the spin-down luminosity of the neutron star.

Fidelity Susceptibility in the Quantum Rabi Model

description: Quantum criticality usually occurs in many-body systems. Recently it was shown that the quantum Rabi model, which describes a two-level atom coupled to a single model cavity field, presents quantum phase transitions from a normal phase to a superradiate phase when the ratio between the frequency of the two level atom and the frequency of the cavity field extends to infinity. In this work, we study quantum phase transitions in the quantum Rabi model from the fidelity susceptibility perspective. We found that the fidelity susceptibility and the generalized adiabatic susceptibility present universal finite size scaling behaviors near the quantum critical point of the Rabi model if the ratio between frequency of the two level atom and frequency of the cavity field is finite. From the finite size scaling analysis of the fidelity susceptibility, we found that the adiabatic dimension of the fidelity susceptibility and the generalized adiabatic susceptibility of fourth order in the Rabi model are $4/3$ and $2$, respectively. Meanwhile the correlation length critical exponent and the dynamical critical exponent in the quantum critical point of the Rabi model are found to be $3/2$ and $1/3$ respectively. Since the fidelity susceptibility and the generalized adiabatic susceptibility are the moments of the quantum noise spectrum which is directly measurable by experiments in linear response regime, the scaling behavior of the fidelity susceptibility in the Rabi model could be tested experimentally. The simple structure of the quantum Rabi model paves the way for experimentally observing the universal scaling behavior of the fidelity susceptibility at a quantum phase transition.

E, {\bf 73}, 021303, 2006] that in steady state of the Oslo ricepile model, the probability of large negative height fluctuations $Δh=-αL$ about the mean varies as $\exp(-κα^4 L^3)$ as $L \to \infty$ with $α$ held fixed, and $κ> 0$.

description: We report the efficient coherent photon scattering from a semiconductor quantum dot embedded in a pillar microcavity. We show that a surface acoustic wave can periodically modulate the energy levels of the quantum dot, but has a negligible effect on the cavity mode. The scattered narrow-band laser is converted to a pulsed single-photon stream, displaying an anti-bunching dip characteristic of single-photon emission. Multiple phonon sidebands are resolved in the emission spectrum, due to the absorption and emission of vibrational quanta in each scattering event.

title: Presence of nonconvexity in groundwater concentration response functions
Creators: name: Ahlfeld, DP
name: Sprong, MP
Publisher: name: University of Massachusetts Amherst
Year: 1998

description: This study examines the presence of nonconvexity and multiple extrema in the feasible region defined by the concentration response function. The response function is defined in the context of concentration constraints imposed on groundwater quality management models and is constructed assuming that concentration constraints are imposed at every node in a numerical grid. The groundwater system is represented by a homogeneous numerical simulation model. The response function is graphically depicted as a function of pumping rates at two wells. The dependence of the response function on simulation model and management model characteristics is examined by varying dimensionless parameter values. This study shows that the response surface is nonconvex and contains multiple local extrema over a wide range of parameter values. These features of the surface are most prominent at the transitions from extraction to injection pumping, Binding constraints often occur at or near low-velocity zones.

description: Research has increasingly highlighted the role that developmental plasticity—the ability of a particular genotype to produce variable phenotypes in response to different early environments—plays as an adaptive mechanism. One of the most widely studied genetic contributors to developmental plasticity in humans and rhesus macaques is a serotonin transporter gene-linked polymorphic region (5-HTTLPR), which determines transcriptional efficiency of the serotonin transporter gene in vitro and modifies the availability of synaptic serotonin in these species. A majority of studies to date have shown that carriers of a loss-of-function variant of the 5-HTTLPR, the short (s) allele, develop a stress-reactive phenotype in response to adverse early environments compared with long (l) allele homozygotes, leading to the prevalent conceptualization of the s-allele as a vulnerability allele. However, this framework fails to address the independent evolution of these loss-of-function mutations in both humans and macaques as well as the high population prevalence of s-alleles in both species. Here we show in free-ranging rhesus macaques that s-allele carriers benefit more from supportive early social environments than l-allele homozygotes, such that s-allele carriers which receive higher levels of maternal protection during infancy demonstrate greater social competence later in life. These findings provide the first empirical support for the assertion that the s-allele grants high undirected biological sensitivity to context in primates and suggest a mechanism through which the 5-HTTLPR s-allele is maintained in primate populations.

description: In the present paper we discuss antenna miniaturization using magneto-dielectric substrates. Recent results found in the literature reveal that advantages over conventional dielectric substrates can only be achieved if natural magnetic inclusions are embedded into the substrate. This observation is revised and the physical background is clarified. We present a detailed discussion concerning magnetic materials available in the microwave regime and containing natural magnetic constituents. The effects of magnetic dispersion and loss are studied: constraints on the microwave permeability are used to estimate the effect of magnetic substrates on the achievable impedance bandwidth. Microwave composites filled with thin ferromagnetic films are considered as a prospective antenna substrate. We calculate the impedance bandwidth for a $λ/2$-patch antenna loaded with the proposed substrate, and challenge the results against those obtained with conventional dielectric substrates. It is shown that the radiation quality factor is strongly minimized with the proposed substrate even in the presence of realistic losses. Estimates for the radiation efficiency are given as a function of the magnetic loss factor.

An empirical model for protostellar collapse

description: We propose a new analytic model for the initial conditions of protostellar collapse in relatively isolated regions of star formation. The model is non-magnetic, and is based on a Plummer-like radial density profile as its initial condition. It fits: the observed density profiles of pre-stellar cores and Class 0 protostars; recent observations in pre-stellar cores of roughly constant contraction velocities over a wide range of radii; and the lifetimes and accretion rates derived for Class 0 and Class I protostars. However, the model is very simple, having in effect only 2 free parameters, and so should provide a useful framework for interpreting observations of pre-stellar cores and protostars, and for calculations of radiation transport and time-dependent chemistry. As an example, we model the pre-stellar core L1544.

description: Four different approximate approaches used to model the stressing of coronal magnetic fields due to an imposed photospheric motion are compared with each other and the results from a full time-dependent magnetohydrodynamic (MHD) code. The assumptions used for each of the approximate methods are tested by considering large photospheric footpoint displacements. We consider a simple model problem, comparing the full nonlinear magnetohydrodynamic evolution, determined with the Lare2D numerical code, with four approximate approaches. Two of these, magneto-frictional relaxation and a quasi-1D Grad-Shafranov approach, assume sequences of equilibria, whilst the other two methods, a second-order linearisation of the MHD equations and Reduced MHD, are time-dependent. The relaxation method is very accurate compared to full MHD for force-free equilibria for all footpoint displacements but has significant errors when the plasma $β_0$ is of order unity. The 1D approach gives an extremely accurate description of the equilibria away from the photospheric boundary layers, and agrees well with Lare2D for all parameter values tested. The linearised MHD equations correctly predict the existence of photospheric boundary layers that are present in the full MHD results. As soon as the footpoint displacement becomes a significant fraction of the loop length, the RMHD method fails to model the sequences of equilibria correctly. The full numerical solution is interesting in its own right, and care must be taken for low $β_0$ plasmas if the viscosity is too large.

description: The LiHo$_x$Y$_{1-x}$F$_4$ magnetic material in a transverse magnetic field $B_{x}\hat x$ perpendicular to the Ising spin direction has long been used to study tunable quantum phase transitions in a random disordered system. We show that the $B_{x}-$induced magnetization along the $\hat x$ direction, combined with the local random dilution-induced destruction of crystalline symmetries, generates, via the predominant dipolar interactions between Ho$^{3+}$ ions, {\it random fields} along the Ising $\hat z$ direction. This identifies LiHo$_x$Y$_{1-x}$F$_4$ in $B_x$ as a new random field Ising system. The random fields explain the rapid decrease of the critical temperature in the diluted ferromagnetic regime and the smearing of the nonlinear susceptibility at the spin glass transition with increasing $B_{x}$, and render the $B_{x}-$induced quantum criticality in LiHo$_x$Y$_{1-x}$F$_4$ likely inaccessible.

description: Abstract: In every civilization and in every age, the women’s role and participation in the labor force have been the center of attention. In order to promote social mobility and provide them equal rights and advantages, it is obviously essential to implement the desired adjustments. Since the dawn of time, women have found it difficult to adjust to a male-dominated society. Despite years of anticipated expansion, women's position remains low in India, and their socioeconomic circumstances are far worse than men's. Objective: The study’s aim is how to empower women in India and search the opinions of the great men of the world. Design and methodology: The integration of both quantitative and qualitative data has yielded a thorough comprehensive study from secondary sources. Results and Discussion: The Third World countries are very much rich having quantum of human beings, which is also quite inadequate in terms of human resources. On the opposite direction, the developed nations are very much rich possessing a large number of human resources but very much poor having quantum of human beings. Therefore, to get developed, the human beings must be converted into human resources. The women constitute half of the population. They must be converted into human resources first to get all round development of any country.  If India wants to be developed and make New Viksit Bharat 2047, India has to give more emphases on women and give equal opportunity to them.  Some of the important points in favour of women are discussed below. Conclusion: Proverb goes that "the happiness f a family lies with the virtues of women". However, how can a pragmatic society aspire to a happy and wealthy life without empowering women? Families are, in fact, a partnership between men and women. Therefore, both men and women should have equal authority in managing families and, consequently, in advancing the country.

description: This paper develops a model based on statistical discrimination theories which predicts that higher educated immigrants have better and less educated immigrants have worse employment prospects in ethnically more diverse regions. Evidence consistent with this hypothesis is found in an empirical analysis. These results, however, also show that even the least educated recent immigrants have higher employment probabilities in ethnically more diverse regions. This suggests that the positive effects of ethnic diversity on overall labour demand compensate for any negative effects on less educated recent immigrants.

description: We demonsrtate electrical spin injection and detection in $n$-type Ge ($n$-Ge) at room temperature using four-terminal nonlocal spin-valve and Hanle-effect measurements in lateral spin-valve (LSV) devices with Heusler-alloy Schottky tunnel contacts. The spin diffusion length ($λ$$_{\rm Ge}$) of the Ge layer used ($n \sim$ 1 $\times$ 10$^{19}$ cm$^{-3}$) at 296 K is estimated to be $\sim$ 0.44 $\pm$ 0.02 $μ$m. Room-temperature spin signals can be observed reproducibly at the low bias voltage range ($\le$ 0.7 V) for LSVs with relatively low resistance-area product ($RA$) values ($\le$ 1 k$Ω$$μ$m$^{2}$). This means that the Schottky tunnel contacts used here are more suitable than ferromagnet/MgO tunnel contacts ($RA \ge$ 100 k$Ω$$μ$m$^{2}$) for developing Ge spintronic applications.

description: We describe the $R$-matrix structure associated with integrable extensions, containing both one-body and two-body potentials, of the $A_N$ Calogero-Moser $N$-body systems. We construct non-linear, finite dimensional Poisson algebras of observables. Their $N \rightarrow \infty$ limit realize the infinite Lie algebras Sdiff$({\Bbb R} \times S_1 )$ in the trigonometric case and Sdiff$({\Bbb R }^2)$ in the rational case. It is then isomorphic to the algebra of observables constructed in the two-dimensional collective string field theory.
