Women Leaders and Spirituality
Creators: name: Harris, Sandra

description: In addressing leadership, there are often two interlocking strands. One of these strands centers on the contributions of leadership grounded in men's leadership experiences (Regan & Brooks, 1995). The second interlocking strand includes feminist attributes. This contributes to nuances of meaning that arise from women's experiences of leadership. Regan and Brooks noted five attributes of leadership among women: collaboration, caring, courage, intuition, and vision. Often these attributes are embedded in firmly held beliefs which are at the heart of a notion of relational leadership. Over twenty years ago, Jaggar (1983) further emphasized that "feminist theory is at its best when it reflects the lived experiences of women, when it bridges the gap between mind and body, reason, and emotion, thinking and feeling" (p. x).

Gender Considerations in the Study of Science and Technology in Anglophone Cameroon

description: When the Germans, who colonised the erstwhile Kamerun after the partition of Africa in 1884, were defeated during the First World War, the League of Nations placed Cameroon under the protectorate of the French and British rule. French- speaking Cameroon gained independence in 1960 and was later joined in 1961 by the English- speaking Cameroon, hereafter known as Francophone and Anglophone Cameroon, respectively. As a consequence, Cameroon's educational system is fashioned along the lines of the French and British systems, which many argue is a reflection of Cameroon's rich cultural diversity. From the nursery through primary to post-secondary school level, the English and French models have respectively existed predominantly in Anglophone and Francophone Cameroon. In 1972, Anglophone Cameroon was cartographically configured into two provinces, the South West and North West, whose population stands at about three million (National Institute of Statistics, 2001). The influence of French and the demographic and geographic superiority of the Francophone Cameroon, with eight provinces and a population according to the National Institute of Statistics (2001) of 12,294,768, have since served as a road map for the course of tertiary education in Cameroon. This has led to a binary system of universities and "grandes ecoles" or specialised institutions, commonly called professional schools. It is at this level that Anglophone students are faced with a myriad of problems, especially in the study of science and technology subjects in institutions where French is the medium of instruction as most of them are based in Francophone Cameroon

description: In the modern iron and steel industry, the efficient distribution of byproduct gases faces significant challenges due to quantity- and quality-related uncertainties of gases. This study presents an optimal approach to gas distribution that addresses this issue by incorporating the energy flow network and the uncertain surplus gases from the manufacturing system. The uncertain optimization problem is formulated as a two-stage robust optimization (TSRO) model, including "here-and-now" decisions aimed at minimizing the start-stop cost of energy conversion units, as well as "wait-and-see" decisions aimed at minimizing the operating cost of gasholders and the penalties resulting from energy excess or shortage. To facilitate practical implementation, we propose a "first quantify, then optimize" approach: (1) quantifying the uncertainty of surplus gases via a conditional quantile regression (CDQ)-based T-step time series model, and (2)finding the optimal solution through a column-and-constraint generation algorithm. Furthermore, a case study is conducted on an industrial energy system to validate the proposed methodology. Computational results, using evaluation indicators, such as MAPE, RMSE, PICP, and PINAW, confirm the effectiveness of the data-driven time series model in accurately quantifying uncertainties in each period. Sensitivity analysis demonstrates that the proposed TSRO model achieves a favorable balance between robustness and flexibility by selecting the combination of "budget and quantile" and the parameters of storage and conversion units. Consequently, TSRO can efficiently find a robust gas distribution solution with the desired level of conservativeness for integrated iron and steel plants.

Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Ideas and theories that consider the intersection of leader diversity and development needs are in the beginning stages of exploration and understanding. The purpose of this study is to explore and understand how women in organizational leadership roles describe their lived experiences of leadership development. Women leaders participated in semistructured interviews with the researcher to explore the participants' perspectives and lived experience of leadership development. Five core meanings and themes were elucidated from interview responses using phenomenological analysis methods. Each theme is discussed and recommendations for future research are considered. The results of this study can be used to inform specific individual-level considerations for women's leadership development, improve leadership development applications, and describe potential actions needed to address the issues that influence women's leadership applications.

description: Weakly supervised person search aims to perform joint pedestrian detection and re-identification (re-id) with only person bounding-box annotations. Recently, the idea of contrastive learning is initially applied to weakly supervised person search, where two common contrast strategies are memory-based contrast and intra-image contrast. We argue that current intra-image contrast is shallow, which suffers from spatial-level and occlusion-level variance. In this paper, we present a novel deep intra-image contrastive learning using a Siamese network. Two key modules are spatial-invariant contrast (SIC) and occlusion-invariant contrast (OIC). SIC performs many-to-one contrasts between two branches of Siamese network and dense prediction contrasts in one branch of Siamese network. With these many-to-one and dense contrasts, SIC tends to learn discriminative scale-invariant and location-invariant features to solve spatial-level variance. OIC enhances feature consistency with the masking strategy to learn occlusion-invariant features. Extensive experiments are performed on two person search datasets CUHK-SYSU and PRW, respectively. Our method achieves a state-of-the-art performance among weakly supervised one-step person search approaches. We hope that our simple intra-image contrastive learning can provide more paradigms on weakly supervised person search. The source code is available at \url{https://github.com/jiabeiwangTJU/DICL}.

description: Using the UVES echelle spectrograph at the ESO VLT we obtained high-resolution (R = 40 000) spectra of the object SDSS J1553+0056, which has been identified in the literature alternatively as a high-redshift quasar or as a Lyman-break galaxy (LBG). Although low-resolution spectra of SDSS J1553+0056 closely resemble those of LBGs, our high-resolution spectra allow us to identify this object unambiguously as a LoBAL quasar, probably belonging to the rare FeLoBALQSO class. Based on our spectrum we discuss how misidentifications of such objects from low-resolution spectra can be avoided.

description: A system comprising two superconducting thin films connected by a point contact is considered. The contact resistance is calculated as a function of temperature and film geometry, and is found to vanish rapidly with temperature, according to a universal, nearly activated form, becoming strictly zero only at zero temperature. At the lowest temperatures, the activation barrier is set primarily by the superfluid stiffness in the films, and displays only a weak (i.e., logarithmic) temperature dependence. The Josephson effect is thus destroyed, albeit only weakly, as a consequence of the power-law-correlated superconducting fluctuations present in the films below the Berezinskii-Kosterlitz-Thouless transition temperature. The behavior of the resistance is discussed, both in various limiting regimes and as it crosses over between these regimes. Details are presented of a minimal model of the films and the contact, and of the calculation of the resistance. A formulation in terms of quantum phase-slip events is employed, which is natural and effective in the limit of a good contact. However, it is also shown to be effective even when the contact is poor and is, indeed, indispensable, as the system always behaves as if it were in the good-contact limit at low enough temperature. A simple mechanical analogy is introduced to provide some heuristic understanding of the nearly-activated temperature dependence of the resistance. Prospects for experimental tests of the predicted behavior are discussed, and numerical estimates relevant to anticipated experimental settings are provided.

Braid groups, orderings, and algorithms
Creators: name: Kim, Djun Maximillian
Publisher: name: University of British Columbia
Year: 2009

description: We define a natural and readily calculated bi-invariant strict total ordering of the n-strand pure braid group Pn. It is defined algebraically, using the Artin decomposition of Pn as a semi-direct product of free groups, together with a specific ordering of free groups using the Magnus expansion. This definition extends to define bi-orderings of more general semi-direct products involving free groups, including the fundamental groups of the complements of fibretype hyperplane arrangements. After basic properties of this "Artin-Magnus" ordering are established, we compare it to existing orderings on Pn, including the restriction of the Dehornoy ordering to Pn. Finally, we present algorithms to compute the Dehornoy ordering on the full braid group Bn, and the Artin-Magnus ordering on Pn. An implementation of these algorithms is included as part of a library of objects for symbolic computation with braids.

description: Currently, there are inequalities in the representation of females in higher administrative positions in higher education, a result of historical and male dominant societal patterns (Byrd-Blake, 2004). While many cultures in the world support and encourage men in their achievement, women are generally discouraged (Brown & Irby, 2001). For many centuries, the opinions of some philosophers and scientists about women and women's education have caused differentiation between women's and men's specializations and their place in society.

description: Today's intelligent computing environments, including Internet of Things, cloud computing and fog computing, allow many organizations around the world to optimize their resource allocation regarding time and energy consumption. Due to the sensitive conditions of utilizing resources by users and the real-time nature of the data, a comprehensive and integrated computing environment has not yet been able to provide a robust and reliable capability for proper resource allocation. Although, traditional methods of resource allocation in a low-capacity hardware resource system are efficient for small-scale resource providers, for a complex system in the conditions of dynamic computing resources and fierce competition in obtaining resources, they do not have the ability to develop and adaptively manage the conditions optimally. To solve this problem, computing intelligence techniques try to optimize resource allocation with minimal time delay and energy consumption. Therefore, the objective of this research is a comprehensive and systematic survey on resource allocation problems using computational intelligence methods under Game Theory and Evolutionary-optimization in emerging computing environments, including cloud, fog and Internet of Things according to the latest scientific-research achievements.

description: A new model for the numerical simulation of a rigid body moving in a viscous fluid flow using FEM is presented. One of the most interesting features of this approach is the small computational effort required to solve the motion of the rigid body, comparable to a pure fluid solver. The model is based on the idea of extending the fluid velocity inside the rigid body and solving the flow equations with a penalization term to enforce rigid motion inside the solid. In order to get the velocity field in the fluid domain the Navier-Stokes equations for an incompressible viscous flow are solved using a fractional-step procedure combined with the two-step Taylor-Galerkin for the fractional linear momentum. Once the velocity field in the fluid domain is computed, calculation of the rigid motion is obtained by averaging translation and angular velocities over the solid. One of the main challenges when dealing with the fluid-solid interaction is the proper modelling of the interface which separates the solid moving mass from the viscous fluid. In this work the combination of the level set technique and the two-step Taylor-Galerkin algorithm for tracking the fluid-solid interface is proposed. The good properties exhibited by the two-step Taylor-Galerkin, minimizing oscillations and numerical diffusion, make this method suitable to accurately advect the solid domain avoiding distortions at its boundaries, and thus preserving the initial size and shape of the rigid body. The proposed model has been validated against empirical solutions, experimental data and numerical simulations found in the literature. In all tested cases, the numerical results have shown to be accurate, proving the potential of the proposed model as a valuable tool for the numerical analysis of the fluid-solid interaction.

description: Galaxy angular momentum directions (spins) are observable, well described by the Lagrangian tidal torque theory, and proposed to probe the primordial universe. They trace the spins of dark matter halos, and are indicators of protohalos properties in Lagrangian space. We define a Lagrangian spin parameter and tidal twist parameters and quantify their influence on the spin conservation and predictability in the spin mode reconstruction in $N$-body simulations. We conclude that protohalos in a more tidal twisting environments are preferentially more rotation-supported, and more likely to conserve their spin direction through the cosmic evolution. These tidal environments and spin magnitudes are predictable by a density reconstruction in Lagrangian space, and such predictions can improve the correlation between galaxy spins and the initial conditions in the study of constraining the primordial universe by spin mode reconstruction.

description: This report included an analysis of 50 accidents involving breakaway-cable-terminal (BCT) end treatments and 19 accidents involving median-breakaway-cable-terminal (BMCT) end treatments. The primary data base consisted of Kentucky accident records for the years 1980-82; with selected accidents included before 1980 and after 1982. An attempt was made to document each accident with a police report, photographs, and a maintenance repair form.  Results showed that the breakaway-cable-terminal end treatment performed properly in most accidents (72 percent); that is, the end treatment performed as it was designed with the wooden posts breaking away or the guardrail redirecting the vehicle. Only four impacts were known to involve small cars and the BCT performed properly in three of those accidents. If trucks are excluded from the analysis, the BCT performed properly in 63 percent of the collisions.  The MBCT end treatment performed properly in 50 percent of the accidents. Problems related to stiffness of the end treatment are most apparent when impact angles are shallow. A recommendation was made to remove any existing MBCT designs from gore area locations and replace them with a crash cushion. A new turned-down end treatment design was proposed for consideration at median installations.

description: We propose a novel scheme for probing vibronic coherence in charge migration in molecules utilizing strong field sequential double ionization. To demonstrate the feasibility of this approach, we perform full simulations of a pump-probe scheme employing few-cycle intense infrared pulses for N$_2$ and O$_2$. We predict that the vibronic coherence between the pumped states will be directly imprinted in experimental observables such as kinetic energy release spectra and branching ratios of the dissociative dications. Our simulations are based on the recently developed DM-SDI model, which is capable of efficiently accounting for molecular orientations and enabling direct comparison with experimental results. Our findings strongly encourage the use of this probing scheme in future charge migration experiments.

description: With a few notable exceptions, most research into the occupational experiences of women is typically macro-social and based on large-scale, impersonal, aggregated, and static data. Whilst such data reveal the position of women in the workforce relative to men, they do not provide sufficient processual insight into the career development of women. Through a case study approach, this study aims to discern patterns in the career development of women managers , and to examine if these patterns conform to career models such as those proposed by White, Cox, and Cooper (1992) and White (1995, 2000). The case data comprise of the career journeys of 20 women managers from a broad cross-section of occupational sectors in New Zealand. The data reveal that although the majority of women managers display high career centrality, they do not work continuously as they have several years of interruptions for bearing and rearing children, and work part-time and retrain themselves through further education before returning to the workplace. Interestingly, they do not seem to plan their careers.

description: Neutron stars are usually modelled as spherical, rotating perfect conductors with a predominant intrinsic dipolar magnetic field anchored to their stellar crust. Due to their compactness, General Relativity corrections must be accounted for in Maxwell's equations, leading to modified interior and exterior electromagnetic solutions. We present analytical solutions for slowly-rotating magnetised neutron stars taking into account the magnetic frame-dragging correction. For typical compactness values, i.e. $R_s \sim 0.5 [R_*]$, we show that the new terms lead to a percent order correction in the magnetic field orientation and strength compared to the case with no magnetic frame-dragging correction. Also, we obtain a self-consistent redistribution of the surface azimuthal current. We verify the validity of the derived solution through two-dimensional particle-in-cell simulations of an isolated neutron star. Defining the azimuthal electric and magnetic field amplitudes during the transient phase as observables, we prove that the magnetic frame-dragging correction reduces the transient wave amplitude, as expected from the analytical solution. We show that simulations are more accurate and stable when we include all first-order terms. The increased accuracy at lower spatiotemporal resolutions translates into a reduction in simulation runtimes.

description: The random variable $1+z_1+z_1z_2+\dots$ appears in many contexts and was shown by Kesten to exhibit a heavy tail distribution. We consider natural extensions of this variable and its associated recursion to $N \times N$ matrices either real symmetric $β=1$ or complex Hermitian $β=2$. In the continuum limit of this recursion, we show that the matrix distribution converges to the inverse-Wishart ensemble of random matrices. The full dynamics is solved using a mapping to $N$ fermions in a Morse potential, which are non-interacting for $β=2$. At finite $N$ the distribution of eigenvalues exhibits heavy tails, generalizing Kesten's results in the scalar case. The density of fermions in this potential is studied for large $N$, and the power-law tail of the eigenvalue distribution is related to the properties of the so-called determinantal Bessel process which describes the hard edge universality of random matrices. For the discrete matrix recursion, using free probability in the large $N$ limit, we obtain a self-consistent equation for the stationary distribution. The relation of our results to recent works of Rider and Valkó, Grabsch and Texier, as well as Ossipov, is discussed.

description: Information technology (IT) has become a popular stage in the working environment due to its overall importance in keeping companies competitive and successful. This is due to information technology being moved from a strictly supporting role in the back office to a position of major strategic importance. The technology field has attracted many qualified candidates including women, who have found themselves among many male contenders. Even though these women were at first attracted to the IT field because of such factors as the number of positions available and high salaries, they were later deterred because of the predominant male culture. This research will study further into the issue of women in the IT working world today and determine if factors such as the glass ceiling, equal pay, family obligations, and education have recently changed.

description: We show from density-functional calculations that Pb(100) thin films exhibit quantum size effect with a bilayer periodicity in film energies, film relaxations, and work functions, which originate from different symmetry of the stacking geometry of odd and even layer films. The bilayer periodicity of the film energy is argued to survive on a semiconductor substrate, which should allow the growth of ``magically'' thick even-layer Pb(100) films. Furthermore, it is found that the quantum well states in a simple metal film can be classified into $σ$-bonded and $π$-bonded states, which quantize independently.

Motivated by previous work on hydrodynamic and magneto-hydrodynamic photoevaporation, we suggest that planets with magnetic fields that are too weak to control the outflow's topology lead to blue-shifted transits due to day-to-night-side flows. In contrast, strong magnetic fields prevent this day-to-night flow, as the gas is forced to follow the magnetic field's roughly dipolar topology. We post-process existing 2D photoevaporation simulations to test this concept, computing synthetic transit profiles in helium. As expected, we find that hydrodynamically dominated outflows lead to blue-shifted transits on the order of the sound speed of the gas. Strong surface magnetic fields lead to unshifted or slightly red-shifted transit profiles. High-resolution observations can distinguish between these profiles; however, eccentricity uncertainties generally mean that we cannot conclusively say velocity shifts are due to the outflow for individual planets. The majority of helium observations are blue-shifted, which could be a tentative indication that close-in planets generally have surface dipole magnetic field strengths $\lesssim 0.1$ gauss. More 3D hydrodynamic and magneto-hydrodynamic are needed to confirm this conclusion robustly.

description: The gluon condensation in the proton as a dynamical model is used to treat a series of unsolved puzzles in sub-TeV gamma ray spectra, they include the broken power-law of blazar's radiation, the hardening confusion of 1ES 1426+428, Mkn 501, and the recently recorded sub-TeV gamma spectra of GRB 180720B and GRB 190114C. We find that the above anomalous phenomena in gamma ray energy spectra can be understood with the simple broken power law based on a QCD gluon condensation effect.

MORPHOLOGY AND PHYSIOLOGY OF FEMALE REPRODUCTION
Creators: name: Mansurova, Dilorom
Publisher: name: Zenodo

description: The female reproductive system functions to produce eggs (ova), sex hormones, and support the development of fertilized eggs into mature fetuses ready for birth. It operates between menarche (the onset of menstruation) and menopause (the cessation of menstruation for 12 consecutive months). Throughout this timeframe, there's a cyclical release of eggs from the ovary, which have the potential to be fertilized by male sperm. This cyclical release of eggs is a natural aspect of the menstrual cycle.

description: We use an all-electron implementation of the GW approximation to analyze several possible sources of error in the theory and its implementation. Among these are convergence in the polarization and Green's functions, the dependence of QP levels on choice of basis sets, and differing approximations for dealing with core levels. In all GW calculations presented here, G and W are generated from the local-density approximation (LDA), which we denote as the \GLDA\WLDA approximation. To test its range of validity, the \GLDA\WLDA approximation is applied to a variety of materials systems. We show that for simple sp semiconductors, \GLDA\WLDA always underestimates bandgaps; however, better agreement with experiment is obtained when the self-energy is not renormalized, and we propose a justification for it. Some calculations for Si are compared to pseudopotential-based \GLDA\WLDA calculations, and some aspects of the suitability of pseudopotentials for GW calculations are discussed.

description: This article is concerned with semilinear time-fractional diffusion equations with polynomial nonlinearity $u^p$ in a bounded domain $Ω$ with the homogeneous Neumann boundary condition and positive initial values. In the case of $p>1$, we prove the blowup of solutions $u(x,t)$ in the sense that $\|u(\,\cdot\,,t)\|_{L^1(Ω)}$ tends to $\infty$ as $t$ approaches some value, by using a comparison principle for the corresponding ordinary differential equations and constructing special lower solutions. Moreover, we provide an upper bound for the blowup time. In the case of $0

description: Slow-roll inflation is analyzed in the context of modified gravity within the Palatini formalism. As shown in the literature, inflation in this framework requires the presence of non-traceless matter, otherwise it does not occur just as a consequence of the non-linear gravitational terms of the action. Nevertheless, by including a single scalar field that plays the role of the inflaton, slow-roll inflation can be performed in these theories, where the equations lead to an effective potential that modifies the dynamics. We obtain the general slow-roll parameters and analyze a simple model to illustrate the differences introduced by the gravitational terms under the Palatini approach, and the modifications on the spectral index and the tensor to scalar ratio predicted by the model.

A Pedagogy of Awareness: Death Education as an Introduction to Social Consciousness

description: I have been teaching a senior level college course entitled Death and Dying - off and on - for more than ten years. At my university it is a philosophy course, though it is multi-disciplinary and could be taught in other departments as well; it is taught around the country in departments of sociology, psychology, health sciences, and religion. I began teaching this course as a result of a tragic loss in my own life. I wanted to bring to others what I had learned as a consequence of that experience and my own exploration through the territory of grief and loss. It seemed to me at the time that most of us are unprepared to deal with some of the blows that life may deal us - especially in contemporary America - and some basic foundational knowledge in this area could enable people to function better in times of crisis than they might without this information.

Modelling the ultraviolet/submillimeter spectral energy distributions of normal galaxies

description: We give an overview of the factors shaping the ultraviolet (UV)/optical - far-infrared (FIR)/submillimeter (submm) spectral energy distributions (SEDs) of normal (non-starburst) galaxies. Particular emphasis is placed on the influen ce of the geometry of dust and stars on the propagation of light through the int erstellar medium. Although strong constraints can be placed on the amount and la rge scale distribution of dust in disks from the appearance of the galaxies in t he optical/UV range, this dust does not account for the observed amplitude and c olour of the FIR/submm radiation. Additional, optically thick components of dust associated with the young stellar population on large and small scales are requ ired to account for the complete UV/optical - FIR/submm SEDs. Self-consistent mo dels for the calculation of SEDs of spiral galaxies are reviewed, and their pred ictions for the dust emission and the attenuation of starlight are compared and contrasted.

description: Polarized hyperon-antihyperon pairs shed light on various unresolved puzzles in contemporary physics: How the strong interaction confines quarks into hadrons, how accurately the Standard Model describes microcosmos and even why our universe consists of so much more matter than antimatter. Thanks to their weak, parity violating decays, hyperons reveal their spin properties. This can be exploited e.g. the decomposition of the electromagnetic structure of hyperons, precision tests of flavour symmetry and searches for CP violation. At the BESIII experiment at BEPC-II, Beijing, China, hyperon-antihyperon pairs can be produced in abundance. Recently collected large data samples have triggered the development of new methods that provide unprecedented precision and a plethora of new results have emerged. When applied at future high-intensity facilities like PANDA and STCF, precision physics will be taken to a new level which can contribute to the solution to the aforementioned puzzles.

Re-Constructing the Leadership Model of Social Justice for African-American Women in Education
Creators: name: Grimes, Mary L.
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: The mainstream epistemology about women in educational leadership roles has been constructed, canonized, and theorized from a white hegemonic female perspective. The early literature about women as leaders include The Managerial Woman (Henning & Jardim, 1977); Men and Women of the Corporation (Kanter, 1977); Paths to Power (Josefowitz, 1980); The Androgynous Manager (Sargent, 1981); Women and Men as Leaders (Heller, 1982); In a Different Voice (Gilligan, 1982); and Feminine Leadership (Loden, 1985). This literature suggests that women lead from a different frame of reference due to their socialization process. Because of male dominated managerial customs that exist in the workplace, in some instances, they experience obstacles to leadership. Recent mainstream white female scholars like Shakeshaft (1989) and Bensimon (1989) suggest that the feminist perspective is not recognized in the leadership literature. Shakeshaft posits that women's leadership experiences are generalized into one category and that the leadership discussion appears androcentric in nature. Bensimon (1989) suggests that the prevailing leadership theories do not take into account that "women experience the social world differently than men do and that this translates into a particular epistemology and a particular ethic.it translates into a different experience of leadership.gender must be taken into consideration" (Bensimon, 1989, p. 146).
