description: The views of 56 female high school principals in the State of Texas were obtained regarding their leadership practices in three areas (i.e., relationship building and decision making, giving and seeking information, and influencing people) which they believed had been beneficial in their positions as high school principals. Respondents viewed supporting employees by being helpful, developing employee skills, and managing conflict as being essential to their success as principals. Moreover, they reported involving their employees in decision-making practices, particularly when critically important decisions must be made. Motivating and inspiring employees was rated highly, although providing tangible rewards was regarded as less important. Individual traits of communication skills, trustworthiness, honesty and sincerity, and good listening skills were very important factors in their success as high school principals. The two individual traits deemed to be less relevant for success in their positions were aggressiveness and tolerance for ambiguity. Finally, cautions regarding generalizability are offered.

description: The precision of Stage IV cosmic shear surveys will enable us to probe smaller physical scales than ever before, however, model uncertainties from baryonic physics and non-linear structure formation will become a significant concern. The $k$-cut method -- applying a redshift-dependent $\ell$-cut after making the Bernardeau-Nishimichi-Taruya transform -- can reduce sensitivity to baryonic physics; allowing Stage IV surveys to include information from increasingly higher $\ell$-modes. Here we address the question of whether it can also mitigate the impact of making the reduced shear approximation; which is also important in the high-$κ$, small-scale regime. The standard procedure for relaxing this approximation requires the repeated evaluation of the convergence bispectrum, and consequently can be prohibitively computationally expensive when included in Monte Carlo analyses. We find that the $k$-cut cosmic shear procedure suppresses the $w_0w_a$CDM cosmological parameter biases expected from the reduced shear approximation for Stage IV experiments, when $\ell$-modes up to $5000$ are probed. The maximum cut required for biases from the reduced shear approximation to be below the threshold of significance is at $k = 5.37 \, h{\rm Mpc}^{-1}$. With this cut, the predicted $1σ$ constraints increase, relative to the case where the correction is directly computed, by less than $10\%$ for all parameters. This represents a significant improvement in constraints compared to the more conservative case where only $\ell$-modes up to 1500 are probed, and no $k$-cut is used. We also repeat this analysis for a hypothetical, comparable kinematic weak lensing survey. The key parts of code used for this analysis are made publicly available.

An Indigenous Perspective on Women Leadership: An Example for Higher Education
Creators: name: Jacobs, Don

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

description: Fielding Graduate University, founded in 1974, offers distributed graduate education and research programs in three social science areas: psychology, human and organizational development, and educational leadership. All three schools affirm a commitment to social change and social justice. The Educational Leadership and Change (ELC) doctoral program was developed in 1996 as a way to influence educational reform and to make doctoral education accessible to working adults, especially those from underserved communities. During its development, the program struggled and faltered as it tried to establish its identity and work toward its goals. After an abrupt change in leadership, two women emerged to form a co-dean leadership team: Susan Tiara, Ph.D. and Judy Witt, Ph.D. Looking for a model that emphasized relationships and a more global outlook, they adopted Total Transformational Management Process (Mink, Esterhuysen, Mink, & Owen, 1993) as the conceptual framework for ELC's governance. Based on action research processes, TTMP utilizes an inclusive model for change that emphasizes the system, "paying special attention to the human side" (p. 11). TTMP was instrumental in developing ELC's way of simultaneously working at the individual, group, and organizational levels and in seeing participatory action research (Park, 1992, 1993) as "transformation concomitant with intense learning" (Mink, et al., 1993, p. 11). Considering the complexity of Fielding's dispersed learning environment, such a transformational priority in leadership, communication, and decision-making became a critical priority for both Fielding and ELC

description: We report first measurements of the doubly charmed baryonic B decays B->Lambda_c+Lambda_c-K. The B+->Lambda_c+Lambda_c-K+ decay is observed with a branching fraction of (6.5+1.0-0.9+-1.1+-3.4)x10^{-4} and a statistical significance of 15.4sigma. The B0->Lambda_c+Lambda_c-K0 decay is observed with a branching fraction of (7.9+2.9-2.3+-1.2+-4.2)x10^{-4} and a statistical significance of 6.6sigma. The branching fraction errors are statistical, systematic, and the error resulting from the uncertainty of Lambda_c+->pK-pi+ decay branching fraction. The analysis is based on 357fb-1 of data accumulated at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e+e- collider.

description: Inspired by the work of Z. Lu and G. Tian [8], A. Loi, F. Salis and F. Zuddas address in [5] the problem of studying those Kähler manifolds satisfying the $Δ$-property, i.e. such that on a neighborhood of each of its points the $k$-th power of the Kähler Laplacian is a polynomial function of the complex Euclidean Laplacian, for all positive integer $k$. In particular, they conjectured that if a Kähler manifold satisfies the $Δ$-property then it is a complex space form. This paper is dedicated to the proof of the validity of this conjecture.

description: The reinforcement of a borosihcate glass with Hastelloy X short fibres is discussed. A fabrication process consisting of wet mixing of the glass powder and the metallic fibres and hot pressing of the mixtures was developed. Composites containing 15 vol.% fibres homogeneously distributed in a near fully dense glass matrix were obtained. Both Young's modulus and fracture strength increased with increasing volume fraction of fibres. The experimental values for the Young's modulus are in agreement with theoretical predictions. No fibre pull-out during fracture was detected and there is a good interfacial bond. By means of a rule-of-mixture calculation for the fracture energy, a five-fold increase in fracture toughness for composites containing 15 vol.% fibres can be predicted.

description: The attenuation of very high energy gamma rays by pair production on the Galactic interstellar radiation field has long been thought of as negligible. However, a new calculation of the interstellar radiation field consistent with multi-wavelength observations by DIRBE and FIRAS indicates that the energy density of the Galactic interstellar radiation field is higher, particularly in the Galactic center, than previously thought. We have made a calculation of the attenuation of very high energy gamma rays in the Galaxy using this new interstellar radiation field which takes into account its nonuniform spatial and angular distributions. We find that the maximum attenuation occurs around 100 TeV at the level of about 25% for sources located at the Galactic center, and is important for both Galactic and extragalactic sources.

The mixed alkali effect revisited - A new look at an old problem
Creators: name: Ingramm, Malcom D.
Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 1994
Subjects: subject: 660

description: Progress is reported in resolving the long-standing problem of the mixed alkali effect. Previously theories have failed to encompass all aspects of this phenomenon which involves both a loosening up of glass structure and the reduction of ionic diffusivities. The recently proposed "dynamic structural model", however, reconciles the electrical and structural anomalies by recoupling ion hopping processes to localized site relaxations in glass. The appearance of a mismatch energy and site memory effects leads to successful prediction of the diffusivity "crossover". This could be the first step towards establishing a consensus on the mixed alkah effect which is reflected in several recent publications on this subject.
The Paradox and the Price: A Case study of Female Academic Managers in an Australian Regional University
Creators: name: Wallace, Michelle
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: This case study presents empirical data regarding the experiences of female academic managers in an Australian regional university. In Australia regional universities are situated in rural towns or cities outside the seven state capital cities and the national capital. This study is intended as a basis for further research in relation to women working in universities and has informed the development of a survey of female middle managers in Australian universities, which will be reported in another paper. This case study focuses on female academics in front-line roles to more senior management roles in what still remains a maledominated management context. The study is also set within the context of a number of pressures on Australian universities, including increased student numbers, decreased government funding, corporatisation and managerialism. The broader restructuring of tertiary education is often accompanied by organizational restructuring at institutional level and this is the case in this study. The management lives of a number of women academics, who are front-line and more senior managers, are examined in the context of sectoral and organizational restructuring, the competitive expectations of managing in new times, and in the context of working in a university in an Australian regional area. Discussion examines human resource development practices and other experiences that have prepared the women for their current roles. Issues surrounding leadership and management styles, workplace culture, work/life balance, and work identity are examined. Conclusions are drawn about the organizational value attributed to the management activities undertaken by these women, the paradoxes a number identify in their roles, and the price several believe they have paid in undertaking managerial leadership

As an application a higher--order version of the Yau--Ahlfors--Schwarz lemma for complete conformal Riemannian metrics is obtained.

description: In the Second part of The Konus-Wind Catalog of Gamma-Ray Bursts with Known Redshifts (first part: Tsvetkova et al. 2017; T17), we present the results of a systematic study of gamma-ray bursts (GRBs) with reliable redshift estimates detected simultaneously by the Konus-Wind (KW) experiment (in the waiting mode) and by the Swift/BAT (BAT) telescope during the period from 2005 January to the end of 2018. By taking advantage of the high sensitivity of BAT and the wide spectral band of KW we were able to constrain the peak spectral energies, the broadband energy fluences, and the peak fluxes for the joint KW-BAT sample of 167 weak, relatively soft GRBs (including four short bursts). Based on the GRB redshifts, which span the range $0.04 \leq z \leq 9.4$, we estimate the rest-frame, isotropic-equivalent energy, and peak luminosity. For 14 GRBs with reasonably constrained jet breaks, we provide the collimation-corrected values of the energetics. This work extends the sample of KW GRBs with known redshifts to 338 GRBs, the largest set of cosmological GRBs studied to date over a broad energy band. With the full KW sample, accounting for the instrumental bias, we explore GRB rest-frame properties, including hardness-intensity correlations, GRB luminosity evolution, luminosity and isotropic-energy functions, and the evolution of the GRB formation rate, which we find to be in general agreement with those reported in T17 and other previous studies.

Tracing Young Women's Career Aspirations From Junior High School into College

description: We have heard the claim that the United States needs more scientists, mathematicians, and engineers to compete in world markets (National Commission on Excellence in Education, 1983; National Science Board (NSB), 1993, 1998, 2004; National Science Foundation (NSF), 1994, 2001; Task Force on Education for Economic Growth, 1983). The intensity of such claims increased with the realization that the majority of the workforce would be women and minorities, who traditionally have not pursued such careers (Bae & Smith, 1996; Johnson & Packer, 1987; NSB, 1998; Oakes, 1990; Stumpf & Stanley, 1996). The NSB (1998) predicted a 44% increase in science and engineering (S&E) occupations from 1996 to 2006. However, women constituted 22% of the S&E work force in 1995 and 25% in 1999 (NSB, 1998, 2004). The largest percentages of women were in the biological sciences (40%) and mathematics/computer science (33%), with much lower percentages in physical science (22% to 23%) and engineering (9% to 10%) (NSB, 1998, 2004).

The transition to single parent adoption for women at midlife
Creators: name: Chopping, Sandra Patricia
Publisher: name: University of British Columbia
Year: 2009

description: A qualitative, phenomenological research design was used to explore the experience of the transition to single parent adoption for women at mid-life. The participants were ten women ranging in age from 43 to 52 years of age who had adopted within the last five years and who had been a parent for at least one year. In individual, in-depth taped interviews, the women described the meaning and experience of the transition to single parent adoption. A thematic analysis procedure based on the work of Colaizzi (1978) was used to develop the common and unique themes of the participants. Analysis of the data revealed there were two patterns that illustrated a complex and challenging transition process. The results of this study are described in relation to their implications for counselling and further research studies.
ESR spectroscopy on glasses and glassy-crystalline materials - New opportunities for material scientists
Creators: name: Stößer, Reinhard

Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 1994
Subjects: subject: 660

description: Analyzing the state of the art of ESR applied to glasses, one can state that all results obtained so far give evidence for the fact that the electron (and nuclear) spin properties are related in a unique manner to the local properties of glassy systems. Therefore, all spin-derived experimental parameters obtained for non-crystalline solids are dispersed around mean values. Suitable theoretical models for an adequate representation of the complex ESR spectra of glasses are reviewed and critically analyzed. The information about the glassy state of matter generated with the help of paramagnetic species offers new opportunities for material sciendsts: criteria for the homogeneity, devitrification and crystallizadon of glasses on a microscopic level; indication of redox processes; localization and function of dopants and their effect on the material properties; evidence for different kinds of internal strain. Some relevant, up to now not commonly used methodical ESR developments like in-situ bending stress experiments, tomography, wide range (4 K ≤ T ≤ 1000 K ) temperature dependence are presented.
Theorizing African American Women's Leadership Experiences: Socio-Cultural Theoretical Alternatives
Creators: name: Byrd, Dr. Marilyn
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Leadership is generally associated with an individual being in a position of authority, and holding a certain measure of power and influence within an organization. However, for African American women (AAW) in predominantly white organizations, race, gender, and social class may restrict the process of leadership. Rather than being mechanisms of leadership, power and influence may be means of restricting AAW's leadership authority over others. Whites often use their privilege to circumvent, diminish, overrule, and control the actions of blacks in the workplace (Deitch et al., 2003). Even blacks in positions of leadership are subject to having their authority undermined. King and Ferguson (1996) suggest the presence of AAW as leaders in predominantly white organizations is in itself ambiguous in that these roles are beyond the customary expectations for black women. Although the number of AAW leaders in predominantly white organizations is increasing (Catalyst, 2004), the dilemma remains that socially constructed hierarchies of race, gender, and social class together may serve to disempower the process of leadership (Collins, 1999). Furthermore, AAW's marginalized status may limit access to social connections in predominantly white organizations. Access to power as well as the freedom to exercise one's own power and authority often lies in informal social networking systems (Gostnell, 1996). Lack of access to these systems may disadvantage the AAW leader's ability to influence organizational processes and actions.

description: We analyze the additional effect on planetary atmospheres of recently detected gamma-ray burst afterglow photons in the range up to 1 TeV. For an Earth-like atmosphere we find that there is a small additional depletion in ozone versus that modeled for only prompt emission. We also find a small enhancement of muon flux at the planet surface. Overall, we conclude that the additional afterglow emission, even with TeV photons, does not result in a significantly larger impact over that found in past studies.

description: We present VLT-FORS spectropolarimetric observations of the type II supernova (SN) 2012aw taken at seven epochs during the photospheric phase, from 16 to 120d after explosion. We correct for the interstellar polarization by postulating that the SN polarization is naught near the rest wavelength of the strongest lines - this is later confirmed by our modeling. SN2012aw exhibits intrinsic polarization, with strong variations across lines, and with a magnitude that grows in the 7000A line-free region from 0.1% at 16d up to 1.2% at 120d. This behavior is qualitatively similar to observations gathered for other type II SNe. A suitable rotation of Stokes vectors places the bulk of the polarization in q, suggesting the ejecta of SN2012aw is predominantly axisymmetric. Using an upgraded version of our 2D polarized radiative transfer code, we model the wavelength- and time-dependent polarization of SN2012aw. The key observables may be explained by the presence of a confined region of enhanced 56Ni at ~4000km/s, which boosts the electron density in a cone having an opening angle of ~50deg and an observer's inclination of ~70deg to the axis of symmetry. With this fixed asymmetry in time, the observed evolution of the SN2012aw polarization arises from the evolution of the ejecta optical depth, ionization, and the relative importance of multiple versus single scattering. However, the polarization signatures exhibit numerous degeneracies. Cancellation effects at early times imply that a low polarization may occur for ejecta with a large asymmetry. An axisymmetric ejecta with a latitude-dependent explosion energy can also yield similar polarization signatures as an asymmetric 56Ni distribution. Despite these uncertainties, SN2012aw provides additional evidence for the generic asymmetry of type II SN ejecta, of which VLT-FORS spectropolarimetric observations are a decisive and exquisite probe.

description: Starspots are usually associated with the action of magnetic fields at the stellar surfaces. However, recently an inhomogeneous chemical distribution of mercury was found for the mercury-manganese (HgMn) star alpha And -- a well-established member of a non-magnetic subclass of the chemically peculiar stars of the upper main sequence. In this study we present first results of the high-resolution survey of the HgII 3984 resonance line in the spectra of rapidly rotating HgMn stars with atmospheric parameters similar to those of alpha And. We use spectrum synthesis modelling and take advantage of the Doppler resolution of the stellar surfaces to probe horizontal structure of mercury distribution. Clear signatures of spots are found in the HgII 3984 line profiles of HR 1185 and HR 8723. Two observations of the latter star separated by two days give evidence for the line profile variability. We conclude that inhomogeneous distribution of Hg is a common phenomenon for the rapidly rotating HgMn stars in the 13000--13800 K effective temperature range independently of the stellar evolutionary stage. These results establish existence of a new class of spectrum variable spotted B-type stars. It is suggested that the observed Hg inhomogeneities arise from dynamical instabilities in the chemical diffusion processes and are unrelated to magnetic phenomena.

Pay and Rank of Female Engineers in Government Service: A Crack in the Glass Ceiling
Creators: name: Sincoff, Michael Z.
name: Baker, Bud
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: In 1991, the United States government began efforts to address the "glass ceiling" and its effects on the federal workforce. This article explores the nature of the glass ceiling, particularly progress made since 1991 on the pay status and hierarchical placement of the almost 200,000 engineers in United States federal civilian employment. When a glass ceiling exists, men occupy a disproportionately high percentage of the higher ranks in a career field, while women tend to be overrepresented in its lower ranks. Similarly, on average men earn higher pay than women in the same organizational rank. These were exactly the conditions of the federal engineering field in 1991, the year of the passage of the Civil Rights Act of 1991 that addressed the glass ceiling, among other topics. In 1991, as a result of the existence of the glass ceiling, women engineers earned only about 81% of the salaries and wages of their male counterparts. Through an exploration of federal employment databases, this article suggests that the condition of women engineers in government service has improved in the years since 1991""more female engineers are on the government rolls, they make up a much larger proportion of senior engineering management, and their compensation is much closer to parity with men""but they are not yet equal with males on any of these dimensions.

description: The ultra-soft narrow-line Seyfert 1 galaxy 1H 0707-495 is a well-known and highly variable active galactic nucleus (AGN), with a complex, steep X-ray spectrum, and has been studied extensively with XMM-Newton. 1H 0707-495 was observed with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) aboard the Spectrum-Roentgen-Gamma (SRG) mission on October 11, 2019, for about 60,000 seconds as one of the first calibration and pointed verification phase (CalPV) observations. The eROSITA light curves show significant variability in the form of a flux decrease by a factor of 58 with a 1 sigma error confidence interval between 31 and 235. This variability is primarily in the soft band, and is much less extreme in the hard band. No strong ultraviolet variability has been detected in simultaneous XMM-Newton Optical Monitor observations. The UV emission is about 10^44 erg s^-1, close to the Eddington limit. 1H 0707-495 entered the lowest hard flux state seen in 20 years of XMM-Newton observations. In the eROSITA All-Sky Survey (eRASS) observations taken in April 2020, the X-ray light curve is still more variable in the ultra-soft band, but with increased soft and hard band count rates more similar to previously observed flux states. A model including relativistic reflection and a variable partial covering absorber is able to fit the spectra and provides a possible explanation for the extreme light-curve behaviour. The absorber is probably ionised and therefore more transparent to soft X-rays. This leaks soft X-rays in varying amounts, leading to large-amplitude soft-X-ray variability.

After the elimination of the influence of the container shape by means of finite element methods, different types of defect show a different behaviour in the Weibull plot. This behaviour can be used to compare different handling materials. The materials used at the cold end cause no measurable weakening of the strength. A special type of defect could be associated with the transfer conveyour belt. Carbon and brass were compared as deadplate materials without finding a specific influence on the container strength.

description: Do people need a lot of money or wealth to be happy? Some social scientists say no. Once people get beyond having their basic needs met, making more money does little to raise the sense of satisfaction (Diener & Seligman, 2002). What, then, makes people happy? According to a new science of happiness, authentic happiness centers on conditions that enable people to flourish in their lives (Seligman, 2003). When asked what conditions brought them the greatest source of happiness, more than 900 women said their greatest sense of happiness came from their children, religious or spiritual life, family connections and friendships, contributing to the lives of others, and leisure and holiday time (Diener & Seligman, 2002). Further, research reported in the Miller, Caldwell, and Lawson (2000), the Sloane Business Review (1991), and by the Business Women's Network (2002) reveals that many professional working women, if given the option, would choose flextime, spending time with family, and helping others over making more money. Other studies show women want friendly and supportive work environments and are, therefore, working with organizational leaders to achieve them. In fact, a recent article, The Opt-Out Revolution, reports that because the corporate world has not enabled conditions that help women flourish, many are unhappy and many others are leaving the traditional corporate world altogether (Belkin, 2003). Thus, while some studies suggest that women are leaving the workplace only for reasons such as maternity leaves or day care problems, this paper suggests that although "motherhood" is very important to women, it is not just about this. Social scientists such as Gallos (1989), Ehrenreich (1995), and Hall (1986) say this trend is more about conditions that impede women's satisfaction with the workplace. Therefore, this study seeks to know more about the conditions which can impede or enhance women's happiness in the workplace.

description: Parity-Time ($\mathcal{PT}$) symmetry has become an important concept in the design of synthetic optical materials, with exotic functionalities such as unidirectional transport and non-reciprocal reflection. At exceptional points, this symmetry is spontaneously broken, and solutions transition from those with conserved intensity to exponential growth or decay. Here we analyze a quantum-photonic surface formed by a single layer of atoms in an array with light mediating strong cooperative many-body interactions. We show how delocalized collective excitation eigenmodes can exhibit an effective $\mathcal{PT}$ symmetry and non-exponential decay. This effective symmetry is achieved in a passive system without gain by balancing the scattering of a bright mode with the loss from a subradiant dark mode. These modes coalesce at exceptional points, evidenced by the emergence of coherent perfect absorption where coherent incoming light is perfectly absorbed and scattered only incoherently. We also show how $\mathcal{PT}$ symmetry can be generated in total reflection and by balancing scattering and loss between different polarizations of collective modes.

description: Glass-ceramics with oriented crystals have been produced from a lithium disilicate glass system by extruding the nucleated glass below the crystallization temperature, and subsequent heat treatment to achieve high-crystalline glass-ceramics. The extruded glass was found to possess a small amount of ahgned, elongated lithium disilicate crystallites and anisotropic stresses. The resulting glassceramic shows a high orientation of the needle-shaped Li₂Si₂O₅ crystals with their c-axis parallel to the extrusion direction. The degree of crystallographic orientation was found to be decreased for samples with an additional heat treatment slightly above Tg, placed between the extrusion process and the crystallization. The crystal alignment of specimens extruded below crystallization temperature is significantly higher than the alignment o f extruded glass-ceramic.

description: Women and minorities continue to be underrepresented in information technology (IT) career fields. In this study, we examined critical self-descriptions of women who selected and excelled in information technology careers. Analysis of six narratives revealed that family support, teachers, and hands-on learning experiences were critical sources of women's development of self-authorship leading to selection of an IT career path. Findings from this research suggest intervention strategies for parents, teachers, and counselors that will encourage more women to pursue careers in information technology.

Speaking up and speaking out: factors that facilitate the disclosure of sexual orientation
Creators: name: Moody, Lin
Publisher: name: University of British Columbia

description: This study explores the things that helped and hindered 12 gay men and lesbians when they disclosed their sexual orientation to others. The goal of this study was to develop a reasonably comprehensive categorical system that described these facilitating and hindering factors from the perspective of the gay men and lesbians participating in this study. The research method involved interviews with six gay men and six lesbians in Vancouver, British Columbia who were in a position to observe what things facilitated their own disclosure process. An expanded version of the Critical Incident Technique (Flanagan, 1954) was utilized to elicit 417 critical incidents from the 12 co-researchers. Thirty-three helping categories and 17 hindering categories emerged from an analysis of the reported incidents. The validity and reliability of all of the categories were backed up by several means including: (a) the use of an independent checker, (b) co-researcher's checking, (c) the existence of complementary helping and hindering categories, (d) theoretical agreement in the research literature, and (e) participation rate. The helping categories that emerged were as follows: (1) acceptance of the authentic self, (2) positive qualities of the disclosee or the relationship, (3) existence of a support network, (4) prediction of a supportive response, (5) conducive environment, (6) assumption that the disclosee already knew, (7) relationship status, (8) desire for more intimacy, (9) spirituality, (10) need to tell, (11) therapy, (12) previous positive disclosures, (13) seizing the moment, (14) access to information, (15) teachable moment, (16) geographical distance, (17) no big deal, (18) sexual deterrent, (19) disclosing by letter or phone, (20) alcohol, (21) other people already know, (22) third party influence, (23) feminist politics, (24) career identity and clout, (25) desire to help others, (26) humour, (27) testing the waters, (28) financial independence, (29) safety and comfort, (30) rehearsal, (31) leaving the church, (32) assumption of confidentiality, and (33) romantic intentions. This thesis also found a strong link between the helping categories elicited in this research study and the domains and thematic components of Ishiyama's (1989) Self- Validation Model. The findings of this study contribute to the field of counselling psychology by providing a list of things that facilitated and hindered the disclosure of 12 gay men's and lesbian's sexual orientation to others. This list could then be shared with clients who are dealing with this issue. The findings also suggest that Ishiyama's (1995) Validationgram might be a useful intervention for this clientele. Results of this study also support the existence of a gay and lesbian positive identity development process.

description: Fairy tales have been described as the remains of ideas and social practices of the past (Yearsley, 1924). As thumbprints of history, fairy tales teach about the cultures of people while entertaining and explaining the world to the next generation (Yolen, 1992; Zeece, 1996). While the tales are valued as a kind of historical archive and a great source of entertainment, researchers have found that fairy tales have an impact in shaping the ways children view the world. Bettelheim (1976) stated that fairy tales are instrumental in stimulating the imagination of children. He and others maintain that fairy tales answer important questions about the world and how it works. These perceptions of how the world works are influential and long-lasting because the impressionable child will make judgments concerning what is admirable in terms of acceptable behaviors and character traits of people based on what they learn in fairy tales (Hurley, 2005; Storr, 1986; Yolen, 1992).

description: A combinadon of two models, deseribing dissoludon of sand grains in bateh blankets or in the molten glass, is presented: a microscale and a macroscale model. The macroscale model is based on a 3-dimensional calculation procedure to determine the temperature distributions and the flows in industrial glass melting tanks. By means of microscale models, using mass transfer relations for diffusional transport, the dissolution rate of single sand grains can be calculated. The dissolution of the sand is determined by following a large number of single grains during their trajectories through the batch blanket and the molten glass in the glass melting tanks. The dissolution rate of a sand grain is calculated for the temperatures and flow conditions i n every volume element in the tank through which the grain proceeds. The dissolution rate in the batch blanket depends strongly on temperature and the stage of the dissolution process. Initially the very fast shrinkage rate of the grains as temperatures exceed 1200°C results within 10 min in the dissolution of more than 50 % of the sand in the blanket. Forced and free convection in the glass melt leads to increases in the dissolution rate, up to a factor 5 compared to motion-free conditions. Forced bubbling for instance results locally in extremely high mass transfer rates and often improves the melting performance of industrial glass furnaces.

description: In the case of a rarefaction fan in a non-stationary Hammersley process, we explicitly calculate the asymptotic behavior of the process as we move out along a ray, and the asymptotic distribution of the angle within the rarefaction fan of a second class particle and a dual second class particle. Furthermore, we consider a stationary Hammersley process and use the previous results to show that trajectories of a second class particle and a dual second class particles touch with probability one, and we give some information on the area enclosed by the two trajectories, up until the first intersection point. This is linked to the area of influence of an added Poisson point in the plane.
