description: Mining clusters from data is an important endeavor in many applications. The $k$-means method is a popular, efficient, and distribution-free approach for clustering numerical-valued data, but does not apply for categorical-valued observations. The $k$-modes method addresses this lacuna by replacing the Euclidean with the Hamming distance and the means with the modes in the $k$-means objective function. We provide a novel, computationally efficient implementation of $k$-modes, called OTQT. We prove that OTQT finds updates to improve the objective function that are undetectable to existing $k$-modes algorithms. Although slightly slower per iteration due to algorithmic complexity, OTQT is always more accurate per iteration and almost always faster (and only barely slower on some datasets) to the final optimum. Thus, we recommend OTQT as the preferred, default algorithm for $k$-modes optimization.

description: We present an improved measurement of the branching fraction for the electroweak penguin process B->Xsll, where l is an electron or a muon and Xs is a hadronic system containing an s-quark. The measurement is based on a sample of 152*10^6 Upsilon(4S) -> BB events collected with the Belle detector at the KEKB energy asymmetric e+e- collider. The Xs hadronic system is reconstructed from one K^{+-} or K^{0}_{S} and up to four pions, where at most one pion can be neutral. Averaging over both lepton flavors, the inclusive branching fraction is measured to be Br(B->Xsll)=(4.11+-0.83(stat)+0.85-0.81(syst))*10^{-6} for M_ll > 0.2GeV/c2.

Simulations and a simple analysis show that the emergent trail pattern flexibly varies depending on the feeding schedule by which ants can make an efficient foraging according to the underlying unsteady environment.

description: Mixed mode oscillatory (MMO) systems are known to exhibit some generic features such as the reversal of period doubling sequences and crossover to period adding sequences as bifurcation parameters are varied. In addition, they exhibit a nearly one dimensional unimodal Poincare map with a longtail. We recover these common features from a general class of two parameter family of one dimensional maps with a unique critical point that satisfy a few general constraints that determine the nature of the map. We derive scaling laws that determine the parameter widths of the dominant windows of periodic orbits sandwiched between two successive states of RL^k sequence. An example of a two parameter map with a unique critical point is introduced to verify the analytical results.

description: We experimentally demonstrate shaping of the two-photon wavefunction of entangled photon-pairs, utilizing coherent pulse-shaping techniques. By performing spectral-phase manipulations we tailor the two-photon wavefunction exactly like a coherent ultrashort pulse. To observe the shaping we perform sum-frequency generation (SFG) with an ultrahigh flux of entangled photons. At the appropriate conditions, SFG performs as a coincidence detector with an ultrashort response time (~100 fs), enabling a direct observation of the two-photon wavefunction. This property also enables us to demonstrate background-free, high-visibility two-photon interference oscillations.

description: The aim of this work is to identify the physical processes that occur in the network and contribute to its dynamics and heating. We model the network as consisting of individual flux tubes with a non-potential field structure that are located in intergranular lanes. With a typical horizontal size of 200 km at the base of the photosphere, they expand upward and merge with their neighbors at a height of about 600 km. Above a height of approximately 1000 km the magnetic field starts to become uniform. Waves are generated in this medium by means of motions at the lower boundary. We focus on transverse driving, which generates both fast and slow waves within a flux tube and acoustic waves at the interface of the tube and the field-free medium. The acoustic waves at the interface are due to compression of the gas on one side of the flux tube and expansion on the other. These waves travel upward along the two sides of the (2D) flux tube and enter it, where they become longitudinal waves. For impulsive excitation with a time constant of 120 s, we find that a dominant feature is the creation of vortical motions that propagate upward. We have identified an efficient mechanism for the generation of longitudinal waves and shock formation in the chromospheric part of the flux concentration. We examine some broad implications of our results.

description: We have obtained a contiguous set of long-slit spectra of a shock wave in the Cygnus Loop to investigate its structure, which is far from the morphology predicted by 1D models. Proper motions from Hubble Space Telescope images combined with the known distance to the Cygnus Loop provide an accurate shock speed. Earlier analyses of shock spectra estimated the shock speed, postshock density, temperature, and elemental abundances. In this paper we determine several more shock parameters: a more accurate shock speed, ram pressure, density, compression ratio, dust destruction efficiency, magnetic field strength, and vorticity in the cooling region. From the derived shock properties we estimate the emissivities of synchrotron emission in the radio and pion decay emission in the gamma rays. Both are consistent with the observations if we assume simple adiabatic compression of ambient cosmic rays as in the van der Laan mechanism. We also find that, although the morphology is far from that predicted by 1D models and the line ratios vary dramatically from point to point, the average spectrum is matched reasonably well by 1D shock models with the shock speed derived from the measured proper motion. A subsequent paper will analyze the development of turbulence in the cooling zone behind the shock.

description: We propose the Positive Resampler to solve the problem associated with event samples from state-of-the-art predictions for scattering processes at hadron colliders typically involving a sizeable number of events contributing with negative weight. The proposed method guarantees positive weights for all physical distributions, and a correct description of all observables. A desirable side product of the method is the possibility to reduce the size of event samples produced by General Purpose Event Generators, thus lowering the resource demands for subsequent computing-intensive event processing steps. We demonstrate the viability and efficiency of our approach by considering its application to a next-to-leading order + parton shower merged prediction for the production of a $W$ boson in association with multiple jets.

description: The lighter chargino pair production ($e^+e^- \to \tildeχ^{+}_{1} \tildeχ^{-}_{1}$) is one of key processes for determination of supersymmetric parameters at a linear collider. If $\tanβ$ is a large value, the lighter stau ($\tildeτ^{\pm}_{1}$) might be lighter than the $\tildeχ^{\pm}_{1}$, while the other sleptons stay heavier. This case leads a cascade decay, $\tildeχ^{\pm}_{1} \to \tildeτ^{\pm}_{1} ν_τ$ followed by $\tildeτ^{\pm}_{1} \to \tildeχ^{0}_{1} τ^{\pm}$, where $\tildeχ^{0}_{1}$ is the lightest supersymmetric particle. This paper addresses to what extent this cascade decay may affect the measurements of the chargino mass and its production cross section.

description: We investigated the kinematics of the pulsar wind nebula (PWN) associated with PSR B1951+32 in the old supernova remnant CTB 80 using the Fabry-Perot interferometer of the 6m Special Astrophysical Observatory telescope. In addition to the previously known expansion of the system of bright filaments with a velocity of 100-200km/s, we detected weak high-velocity features in the H-alpha line at least up to velocities of 400-450km/s. We analyzed the morphology of the PWN in the H-alpha, [SII], and [OIII] lines using HST data and discuss its nature. The shape of the central filamentary shell, which is determined by the emission in the [OIII] line and in the radio continuum, is shown to be consistent with the bow-shock model for a significant (about 60 degrees) inclination of the pulsar's velocity vector to the plane of the sky. In this case, the space velocity of the pulsar is twice higher than its tangential velocity, i.e., it reaches ~500 km/s, and PSR B1951+32 is the first pulsar whose line-of-sight velocity (of about 400 km/s) has been estimated from the PWN observations. The shell-like H-alpha-structures outside the bow shock front in the east and the west may be associated with both the pulsar's jets and the pulsar-wind breakthrough due to the layered structure of the extended CTB 80 shell.

description: We present a systematic study on the exciton relaxation in high purity AlGaAs epilayers. The time for the excitonic photoluminescence to reach its maximum intensity (t_max) shows a non-monotonic dependence on excitation density which is attributed to a competition between exciton localization and carrier-carrier scattering. A phenomenological four level model fully describes the influence of exciton localization on t_max. This localization effect is enhanced by the increase of the Al content in the alloy and disappears when localization is hindered by rising the lattice temperature above the exciton trapping energy.

description: Forecasting the evolution of contagion dynamics is still an open problem to which mechanistic models only offer a partial answer. To remain mathematically or computationally tractable, these models must rely on simplifying assumptions, thereby limiting the quantitative accuracy of their predictions and the complexity of the dynamics they can model. Here, we propose a complementary approach based on deep learning where the effective local mechanisms governing a dynamic on a network are learned from time series data. Our graph neural network architecture makes very few assumptions about the dynamics, and we demonstrate its accuracy using different contagion dynamics of increasing complexity. By allowing simulations on arbitrary network structures, our approach makes it possible to explore the properties of the learned dynamics beyond the training data. Finally, we illustrate the applicability of our approach using real data of the COVID-19 outbreak in Spain. Our results demonstrate how deep learning offers a new and complementary perspective to build effective models of contagion dynamics on networks.
Mitakuye Oyas’in : performing trauma to strength
Creators: name: Giard, Marie Annette Monique
Publisher: name: University of British Columbia
Year: 2009

description: Mitakuye Oyas’in is a creative non-fiction addressing the root causes of presentday conditions of fifteen urban Native youth. After uncovering individual as well as collective stories of discrimination and violence through the process of personal narratives (spilaxem) and re-enactment, fifteen urban Native youth developed and conducted anti-racist and anti-bullying workshops aimed at transforming hurt into hope. This performative-intervention becomes a healing process as youth gradually take on new relational roles and perform 'a head taller' as community leaders, role models, and healers for themselves and their peers. Section One explores youth spilaxem and the co-creation of a holding environment for stories of hurt to be shared. Section Two addresses recovering emotional and physical aspects of trauma, remembering and sharing experiences and commonalities through re-enactment and video-making. Section Three provides creative ways of Performing Trauma to Strength sqilxwcut (the Indian Way) by calling the circle, and annunciating hope within a larger community, The last chapter demonstrates the efficacy of Performing Trauma to Strength as a preventative and healing intervention with youth inside and outside classrooms. Through Performing Trauma to Strength, First Nations youth in particular are offered opportunities for healing and growth as they engage in all phases of the performance project. Performing Trauma to Strength can be construed as a ritual of social integration and social justice. For people who have endured acts of violence, those who find refuge within themselves or in 'acting out' their suffering, or those who have not found a purpose for living, Mitakuye Oyas’in is an inspirational model aiming to re-ignite the fire of life and rekindle the vitality of living Seven animal-icons from the Medicine Wheel appear along the journey bringing wisdom and ancestral epistemologies. A tressage approach, where interconnectedness is paramount, includes ancestral as well as newer ways of being in the world, interweaving theory and practice (tool-and-result) in the unfolding of Performing Trauma to Strength.

A unification scheme for classical and quantum mechanics at all velocities

Year: 2004
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: From a Newtonian-Maxwellian solution for a perturbed vacuum with a physical structure constructed based on pivotal experimental observations, we have achieved a general scheme for the formation of basic material particles. A basic particle, which may be e.g. an electron, is composed of a tiny free aether-pole (a bare charge) and the mechanical wave disturbances -- identifying with electromagnetic waves -- generated by it in the medium. When in motion, as a result of a first kind source effect, this particle wave exhibits all of wave and dynamic properties known for a de Broglie wave, and is here called a Newton- de Broglie (NdB) particle wave. In a confined space, the Newtonian solution for the NdB particle wave is equivalent to that given by Schrodinger's quantum mechanics. Through this general scheme we have accomplished a basic task of the unification of the classical- and the quantum- mechanics, both in terms of the deduction of the latter from the former, and the convergence of the latter into the former at high velocities. Through completing the task, we unfold the origins of a series of phenomena including the electromagnetic waves, the electromagnetic radiation and absorption, atomic and thermal excitations, the inertial mass, the Schrodinger's wavefunction and de Broglie wave, the Heisenberg's uncertainty relation, the de Broglie relations, the simultaneous existence of electron and positron or generally of particles and their anti-particles, the (rest) mass-energy equivalence relation, etc. The general scheme facilitates also a Theory of Relative Motion which we present in a separate paper, II; a series of followed studies are planned. (An original report of the scheme with a Preface remarking on the changes in later publications.)

description: We have measured the second-order correlation function of the cavity-QED microlaser output and observed a transition from photon bunching to antibunching with increasing average number of intracavity atoms. The observed correlation times and the transition from super- to sub-Poisson photon statistics can be well described by gain-loss feedback or enhanced/reduced restoring action against fluctuations in photon number in the context of a quantum microlaser theory and a photon rate equation picture. However, the theory predicts a degree of antibunching several times larger than that observed, which may indicate the inadequacy of its treatment of atomic velocity distributions.

description: In this paper we use Newton's 3rd law to deduce the simplest model of an object that can perform a standing vertical jump -- a two-segmented object with an initial constant repulsive force between the segments, followed by an abrupt attractive force. Such an object, when placed on a sturdy ground, will jump, and the motion can be calculated using only the constant acceleration equations, making the example suitable for algebra-based physics. We then proceed to solve for the motion of an n-segmented object, and determine the optimal number of segments for jumping. We then discuss a few similarities and differences of this simple model from jumping robots and jumping humans, and then conclude by arguing the model's pedagogical merits.

description: We observed Sgr A* using the Very Large Array (VLA) and the Giant Metrewave Radio Telescope (GMRT) at multiple cm and mm wavelengths on 17 June 2003. The measured flux densities of Sgr A*, together with those obtained from the Submillimeter Array (SMA) and the Keck II 10 m telescope on the same date, are used to construct a simultaneous spectrum of Sgr A* from 90 cm to 3.8 $μ$m. The simultaneous spectrum shows a spectral break at about 3.6 cm, a possible signature of synchrotron self-absorption of the strong radio outburst which occurred near epoch 17 July 2003. At 90 cm, the flux density of Sgr A* is $0.22\pm0.06$ Jy, suggesting a sharp decrease in flux density at wavelengths longer than 47 cm. The spectrum at long cm wavelengths appears to be consistent with free-free absorption by a screen of ionized gas with a cutoff $\sim$100 cm. This cutoff wavelength appears to be three times longer than that of $\sim$30 cm suggested by Davies, Walsh & Booth based on observations in 1974 and 1975. Our analysis suggests that the flux densities of Sgr A* at wavelengths longer than 30 cm could be attenuated and modulated by stellar winds from massive stars close to Sgr A*.

Exploring group-based life review with family physicians : constructing narratives of experience and meaning
Creators: name: Pearson, Hilary Mary
Publisher: name: University of British Columbia
Year: 2009

description: This narrative research study was inspired by a desire to expand professional development opportunities for family physicians in Canada. Research points to increasing numbers of physicians who are unable or unwilling to continue practicing because of the overwhelming stress experienced in their work. Self-care, disclosure of personal difficulties, collegiality and help-seeking have not traditionally been fostered in medical culture and difficulties are often denied or go unnoticed until they reach a critical point. Recognizing that the current medical practice environment places the morale and sustainability of many physicians in jeopardy has underscored the importance of developing a range of initiatives to support physicians in their work and reduce professional isolation. Group-based life review is a semi-structured process designed to combine individual reflection and writing about one's experiences with sharing life stories in a small group context. It has the potential to promote self-awareness, interpersonal learning and a sense of connection and mutual support among group members. The purpose of this inquiry was to create an understanding of the multiple meanings that six family physicians made about their participation in a seven-week professional development program grounded in group-based life review. The goal of the inquiry was to gain an understanding from the participants diverse perspectives that could shed light on the viability of using group-based life review with family doctors as a means to enhance well-being and sustainability and illuminate the potential benefits and drawbacks of this approach within the context of their personal experiences and professional culture. A reflexive collaborative narrative research methodology combined with participant inquiry was used to investigate the research question and to co-construct an in-depth understanding of how each of the participants experienced joining with colleagues in the life review program. The six narratives presented in this document provide a multi-focal perspective of the experience of participating in the program and contribute to understanding the viability and effectiveness of life review as one possible means to promote well-being, collegiality and sustainability among family doctors. The doctor's stories also illuminate some of the ways in which current medical discourses impact professional development opportunities for family physicians and raise issues and questions that merit further attention by both practitioners and researchers who are seeking to develop effective initiatives to support family doctors. The narratives and thematic results that were generated in this exploratory inquiry indicate that the life review program was experienced as an effective way to promote self-care, mutual support, a sense of community and enhanced sustainability among family physicians.

description: In order to explore the conditions of successful irrigation management, this study investigates the determinants of household contributions to the cleaning of irrigation channels and the availability of water. By using primary data collected in an irrigation scheme in Uganda, we find that household contributions to the cleaning of irrigation channels are determined by the scarcity of irrigation water, opportunity cost of labor, and private benefit associated with plot size. We also find that the availability of irrigation water increases in the tertiary irrigation area where the coefficient of variation of plot size is large.
Higgs mass in the gauge-Higgs unification

description: The gauge-Higgs unification theory identifies the zero mode of the extra dimensional component of the gauge field as the usual Higgs doublet. Since this degree of freedom is the Wilson line phase, the Higgs does not have the mass term nor quartic coupling at the tree level. Through quantum corrections, the Higgs can take a vacuum expectation value, and its mass is induced. The radiatively induced mass tends to be small, although it can be lifted to ${\mathcal O}(100)$ GeV by introducing the ${\mathcal O}(10)$ numbers of bulk fields. Perturbation theory becomes unreliable when a large number of bulk fields are introduced. We reanalyze the Higgs mass based on useful expansion formulae for the effective potential and find that even a small number of bulk field can have the suitable heavy Higgs mass. We show that a small (large) number of bulk fields are enough (needed) when the SUSY breaking mass is large (small). We also study the case of introducing the soft SUSY breaking scalar masses in addition to the Scherk-Schwarz SUSY breaking and obtain the heavy Higgs mass due to the effect of the scalar mass.

description: We study self-similar attractors in the space $\mathbb{R}^d$, i.e., self-similar compact sets defined by several affine operators with the same linear part. The special case of attractors when the matrix $M$ of the linear part of affine operators and the shifts are integer, is well known in the literature due to many applications in the construction of wavelet and in approximation theory. In this case, if an attractor has measure one, it is called a tile. We classify self-similar attractors and tiles in case when they are either polyhedra or union of finitely many polyhedra. We obtain a complete description of the integer contraction matrices and of the digit sets for tiles-parallelepipeds and for convex tiles in arbitrary dimension. It is proved that on a two-dimensional plane, every polygonal tile (not necessarily convex) must be a parallelogram. Non-trivial examples of multidimensional tiles which are a finite union of polyhedra are given, and in the case $d = 1$ their complete classification is provided. Applications to orthonormal Haar systems in $\mathbb{R}^d$ and to integer univariate tiles are considered.

A simple formula for pooling knowledge about a quantum system
Creators: name: Jacobs, Kurt
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: When various observers obtain information in an independent fashion about a classical system, there is a simple rule which allows them to pool their knowledge, and this requires only the states-of-knowledge of the respective observers. Here we derive an equivalent quantum formula. While its realm of applicability is necessarily more limited, it does apply to a large class of measurements, and we show explicitly for a single qubit that it satisfies the intuitive notions of what it means to pool knowledge about a quantum system. This analysis also provides a physical interpretation for the trace of the product of two density matrices.

title: Essays on capacity underutilization and demand driven business cycles
Creators: name: Sun, Tiancheng
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: In Chapter 1, I build a macroeconomic model that features chronic excess capacity. In my model, if one firm expands its capacity while other firms do not, it \steals" profitable demand from others. This capacity competition externality can cause an over-investment in capacity. I show that with the existence of chronic excess capacity, capital resources can be slack and consumption demand shocks can generate realistic business cycles. If consumption demand increases, more capacity will be utilized, heating up the capacity competition: firms invest with haste until the capacity utilization rate falls back to normal. If consumption demand decreases, more capacity will be left idle, cooling down the capacity competition: firms dis-invest with haste until the capacity utilization rate goes back to normal. In Chapter 2, I show that the above results cannot be obtained in models with efficient utilization of capital or capacity. In these models, there is no capacity competition externality. None of these models could feature chronic excess capacity nor capital resource slackness. Thus, the response of output to demand shocks is limited and it is difficult to obtain demand driven business cycles in these models. In Chapter 3, I study what kind of goods market structure features the capacity competition externality that can cause chronic excess capacity. The following assumptions are identified. First, if a firm expands its capacity while other firms do not, it can \steal" demand from others. Second, firms can charge a sufficiently high price to make a positive net profit. These two assumptions imply a negative capacity competition externality and are sufficient to cause long-term capacity underutilization at the firm-level. Third, if the invested capital has no positive externality that can potentially offset the negative externality, the capacity competition externality will be dominant and the economy will exhibit chronic excess capacity. I present several different ways to micro-found this kind of goods market structure, demonstrating the generality of the results obtained in the previous chapters.
A Perturbative QCD Based Study of Polarized Nucleon Structure in the Transition Region and Beyond: "Quarks, Color Neutral Clusters, and Hadrons"

description: A large fraction of the world data on both polarized and unpolarized inclusive $ep$ scattering at large Bjorken $x$ lies in the resonance region where a correspondence with the deep inelastic regime, known as Bloom and Gilman's duality, was observed. Recent analyses of the $Q^2$ dependence of the data show that parton-hadron duality is inconsistent with the twist expansion at low values of the final state invariant mass. We investigate the nature of this disagreement, and we interpret its occurrence in terms of contributions from non partonic degrees of freedom in a preconfinement model.

description: This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the improved groundnut varieties. The potential adoption rate of improved groundnut for the population is estimated at 37% and the adoption gap resulting from the incomplete exposure of the population to the improved groundnut is 12%. We further find that the awareness of improved varieties is mainly influenced by information access variables, while adoption is largely influenced by economic constraints. The findings are indicative of the relatively large unmet demand for improved groundnut varieties suggesting that there is scope for increasing the adoption rate of improved groundnut varieties in Malawi once the farmers are made aware of the technologies and if other constraints such as lack of access to credit are addressed.
Monte Carlo Simulation of Deffuant opinion dynamics with quality differences

description: In this work the consequences of different opinion qualities in the Deffuant model were examined. If these qualities are randomly distributed, no different behavior was observed. In contrast to that, systematically assigned qualities had strong effects to the final opinion distribution. There was a high probability that the strongest opinion was one with a high quality. Furthermore, under the same conditions, this major opinion was much stronger than in the models without systematic differences. Finally, a society with systematic quality differences needed more tolerance to form a complete consensus than one without or with unsystematic ones.

description: The article presents how Euroregions contribute to the execution of Lisbon Strategy’s objectives to ensure its positive outcomes. As „special” regions, Euroregion are the embodiment of entrepreneurship and they strive to be competitive. Because the Lisbon Strategy emphasised entrepreneurship-based competitiveness, especially the competitiveness of the SME sector, Euroregions, representing “natural entrepreneurship” and a basis for SME development, carried out their “mission” in line with the Lisbon Strategy.
Coulomb and Higgs Branches from Canonical Singularities: Part 0

description: Five- and four-dimensional superconformal field theories with eight supercharges arise from canonical threefold singularities in M-theory and Type IIB string theory, respectively. We study their Coulomb and Higgs branches using crepant resolutions and deformations of the singularities. We propose a relation between the resulting moduli spaces, by compactifying the theories to 3d, followed by 3d $\mathcal{N}=4$ mirror symmetry and an $S$-type gauging of an abelian flavor symmetry. In particular, we use this correspondence to determine the Higgs branch of some 5d SCFTs and their magnetic quivers from the geometry. As an application of the general framework, we observe that singularities that engineer Argyres-Douglas theories in Type IIB also give rise to rank-0 5d SCFTs in M-theory. We also compute the higher-form symmetries of the 4d and 5d SCFTs, including the one-form symmetries of generalized Argyres-Douglas theories of type $(G, G')$.

description: The objective of this paper is to present and analyze preliminary some selected methodological consequences of the disputes held between modernists and post-modernists for the contemporary theory of the firm. There is no doubt that the subject of these disputes constitutes the main axis in the discussion on the structure and functioning of the modern enterprise. In the situation of the intense debate between modernists and post-modernists, it appears that chances of the economic theory of the firm to find explicit answers to the questions on the essence and causes of establishing the enterprise are decreasing. However, at the same time our knowledge on the causes and mechanisms of differentiating enterprises in current market economies is increasing. The achievements of philosophy and methodology of science allow us to formulate a hypothesis that this is going to be a lasting situation.

description: Effective leadership always plays an important role in the growth and better performance of the organization. This research has been conducted to determine the impact of transformational and transactional leadership style on job success and career satisfaction. A total of 240 responses (n = 240) from various private organizations working in the capital city of Pakistan were collected using various measures of TLI Questionnaire along with items of job success and career satisfaction. Results showed positive trends of all variables. Transactional leadership is found significantly related to job success while transformational leadership and job success are found highly related with career satisfaction. The results of regression analysis show that job success is more dependent on transformational and transactional leadership as compared to career satisfaction. Managerial implications are presented based upon these results.

description: Motivated by regularities observed in time series of returns on speculative assets, we develop an asymptotic theory of GARCH(1,1) processes {y_k} defined by the equations y_k=σ_kε_k, σ_k^2=ω+αy_{k-1}^2+βσ_{k-1}^2 for which the sum α+βapproaches unity as the number of available observations tends to infinity. We call such sequences near-integrated. We show that the asymptotic behavior of near-integrated GARCH(1,1) processes critically depends on the sign of γ:=α+β-1. We find assumptions under which the solutions exhibit increasing oscillations and show that these oscillations grow approximately like a power function if γ\leq 0 and exponentially if γ>0. We establish an additive representation for the near-integrated GARCH(1,1) processes which is more convenient to use than the traditional multiplicative Volterra series expansion.
