description: Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser ablation in solids. It is well understood that an intense fs laser pulse can remove several electrons from an atom within its pulse duration. [1] However, the speed of electron localization out of an electron gas, the capture of an electron by ion, is unknown. Here, we demonstrate that electronic localization out of the conduction band can occur within only a few hundred femtoseconds. This ultrafast electron localization into 4f states has been directly quantified by transient x-ray absorption spectroscopy following photo-excitation of a Eu based correlated metal with a fs laser pulse. Our x-ray experiments show that the driving force for this process is either an ultrafast reduction of the energy of the 4f states, a change of their bandwidth or an increase of the hybridization between the 4f and the 3d states. The observed ultrafast electron localization process raises further basic questions for our understanding of electron correlations and their coupling to the lattice.

I show that a consistent perturbative resummation of collinear and energy logs is now possible, and necessary if one wishes to use recent NNLO results in the HERA kinematic region.

description: We take a fresh look at Feynman diagrams in the spinor-helicity formalism. Focusing on tree-level massless QED and QCD, we develop a new and conceptually simple graphical method for their calculation. In this pictorial method, which we dub the chirality-flow formalism, Feynman diagrams are directly represented in terms of chirality-flow lines corresponding to spinor inner products, without the need to resort to intermediate algebraic manipulations.

description: Today organisational stress is becoming a matter of concern for all organisations. Organisational stress in employees is emerging as a black plaque in the current scenario. Organisations are therefore trying to come up with innovations to help their employees cope up with stress. In the last few years, the advent of technology and modernisation has overburdened the workers and pushed them into pits of distress. An attempt has been therefore made to understand the stressors and the innovations in the field of human resource management to cope up with these stressors. The major innovations and practises recognised in this study include using the Holmes and Rahe Stress Scale, 20%-time policy, artificial intelligence and ABC technique. The techniques reviewed in this paper describes the most recent innovations in the area of human capital innovations for stress management.

description: We study compactifications of Einstein gravity on product spaces in vacuum and their acceleration phases. Scalar potentials for the dimensionally reduced effective theory are found to be of exponential form and exact solutions are obtained for a class of product spaces. The inflation in our solutions is not sufficient for the early universe. We comment on the possibility of obtaining sufficient inflation by compactification in general.

description: We present an analysis of a system of weakly coupled Hubbard chains based on combining an exact study of spectral functions of the uncoupled chain system with a renormalization group method for the coupled chains. For low values of the onsite repulsion $U$ and of the doping $δ$, the leading instability is towards a superconducting state. The process includes excited states above a small correlation pseudogap. Similar features appear in extended Hubbard models in the vicinity of commensurate fillings. Our theoretical predictions are consistent with the phase diagram observed in the (TMTTF)$_2$X and (TMTSF)$_2$X series of organic compounds.

A CONTENT ANALYSIS OF SIX MANAGEMENT JOURNALS ALONG SELECTED DIMENSIONS OF GENERAL BUSINESS MANAGEMENT: 1966-1986
Creators: name: Tyler, Richard Frederic
Publisher: name: American University
Year: 2023

description: The purpose of this study was to examine the content of a sample of six representative journals in the field of management, for the years 1966 through 1986, to ascertain trends and emphasis along four dimensions of general business management--"planning, organizing, motivating, and controlling." The journals selected were the Administrative Science Quarterly, Harvard Business Review, Journal of Business, Management Science, Public Administration Review, and the Sloan Management Review. The findings from this examination were interpreted for their meaning to college faculty and students studying general business management. All 2,085 articles in the six journals were examined of which 731 focused on one of the four dimensions of management and were selected for the following analysis: first, the number of articles per journal, per year, for each dimension of management; second, by article length (which was converted into standard inches for comparative purposes); and third, by percentage of articles and number of standard inches along a dimension of management by year and over the entire time frame of the study. The findings revealed that the journals taken altogether were consistent in the number of articles on and standard inches devoted to the four dimensions of management during the period of examination. When looking at the journals individually, and interpreting their usefulness to college faculty and students of management, the Harvard Business Review and the Public Administration Review revealed a balance in their treatment of the dimensions of management analyzed, making them good general resources for management students and faculty; whereas the Journal of Business provided the least balance (with no consideration for the dimension "organizing") making it the most specialized. More so than the other publications, the ASO gave attention to "planning," the SMR to "controlling," and the MS to the four management dimensions as a group in proportion to its total content. Among the four management dimensions, "controlling" was given the most attention by the aggregate of six journals in terms of number of articles and standard inches.

description: The exact canonical partition function of a hard disk system in a narrow quasi-one dimensional pore of given length and width is derived analytically in the thermodynamic limit. As a result the many body problem is reduced to solving two transcendental equations which can be easily done numerically. The longitudinal and transverse pressures in the whole density range are presented for three different pore widths. The transition from the solidlike zigzag to the liquidlike state is found to be quite sharp in the density scale but shows no genuine singularity. This transition is quantitatively described by the distribution of zigzag's windows through which disks exchange their positions across the pore.

description: Historical changes in the structure of agriculture have led to the creation of a heterogeneous hired farm labor force. However, the conceptual process relating to this occupational group has not kept pace with agricultural development and theory, research, and policy relating to hired farmworkers have suffered as a result. This research measures the extent, nature, and implications of structural diversity within the U.S. hired farm work force by examining worker differences in level of attachment to farm and nonfarm work. Data from the U.S. Department of Agriculture's Agricultural Work Force Survey are used to develop a typological model which identifies three groups of hired farmworkers: those attached to farmwork, those attached to nonfarm work, and those casually attached to work. Univariate and multivariate techniques test the utility of this typology for understanding the structure of the hired farm work force. The empirical analysis indicates that these groups of farmworkers differ substantially in their demographic characteristics, socioeconomic status, and employment experiences. Study results indicate that workers who are strongly attached to farmwork are segmented into two groups. Some of these workers are in secondary jobs with low status and rewards; others experience higher earnings and better working conditions, but are still economically disadvantaged compared to other occupational groups. Farmworkers who are attached to nonfarm work differ by their income status. Some of these workers are in low income families and are contributing necessary income to the family; others with higher incomes are combining farm and nonfarm jobs to improve their standard of living. Some farmworkers who are casually attached to the work force are providing necessary family income, but others have relatively high family incomes and do farm and nonfarm work for extra spending money or to obtain entry level job experience. The structural diversity identified in this study indicates that different groups of workers experience different problems and needs based in large part on their original motivation for seeking employment on U.S. farms. The presence of structural diversity has important implications for theory, research, and policy which have historically been based on a homogeneous image of hired farmworkers.

THE DIFFUSION OF NUMERICALLY-CONTROLLED TOOLS
Creators: name: Fenster, Lawrence Elliot
Publisher: name: American University
Year: 2023

description: In order for productivity to improve, not only must new technologies be adopted, they must become widespread. Identifying the determinants of the conversion of capital stock to a new technology would aid the public discussion of how to improve efficiency in the manufacturing sector. This dissertation estimates the determinants of the conversion of turning tools to numerical-control by the U.S. metalworking sector, using two models of diffusion: an epidemic model and a probit model. The empirical evidence suggests that the probit model provides superior estimates of the determinants of conversion to numerically-controlled turning tools. Competitive market structure has often been chosen as a possible determinant of technological diffusion. However, prior studies have estimated its effect as negative, positive and insignificant. This study found competitive market structure to be positively correlated with diffusion. Furthermore, market structure accounted for 32% of the explained variation of estimated diffusion rates from their mean. This study examined the influence of the ability of a corporation to bear risk, by estimating the effect of the degree of labor stability. It was hypothesized that industries which provided stable employment to their workforce would receive greater labor cooperation upon the introduction of a new technology. This, in turn, would aid diffusion. The empirical evidence supports this hypothesis. Separation rates were found to be negatively correlated with diffusion rates. They made the largest contribution of any variable (42%) to the explained variation of estimated diffusion rates from their mean. These results, along with the finding that diffusion was faster in industries with low ratios of labor to capital, suggest that even though numerically-controlled tools are labor replacing, industries with more stable employment converted to numerical-control more quickly.
Future Evolution of the Intergalactic Medium in a Universe Dominated by a Cosmological Constant

description: We simulate the evolution of the intergalactic medium (IGM) in a universe dominated by a cosmological constant. We find that within a few Hubble times from the present epoch, the baryons will have two primary phases: one phase composed of low-density, low-temperature, diffuse, ionized gas which cools exponentially with cosmic time due to adiabatic expansion, and a second phase of high-density, high-temperature gas in virialized dark matter halos which cools much more slowly by atomic processes. The mass fraction of gas in halos converges to ~40% at late times, about twice its calculated value at the present epoch. We find that in a few Hubble times, the large scale filaments in the present-day IGM will rarefy and fade away into the low-temperature IGM, and only islands of virialized gas will maintain their physical structure. We do not find evidence for fragmentation of the diffuse IGM at later times. More than 99% of the gas mass will maintain a steady ionization fraction above 80% within a few Hubble times. The diffuse IGM will get extremely cold and dilute but remain highly ionized, as its recombination time will dramatically exceed the age of the universe.

description: We investigate theoretically and experimentally the center-of-mass motion of an ideal Fermi gas in a combined periodic and harmonic potential. We find a crossover from a conducting to an insulating regime as the Fermi energy moves from the first Bloch band into the bandgap of the lattice. The conducting regime is characterized by an oscillation of the cloud about the potential minimum, while in the insulating case the center of mass remains on one side of the potential.

description: Interconnected ensembles of biological entities are perhaps some of the most complex systems that modern science has encountered so far. In particular, scientists have concentrated on understanding how the complexity of the interacting structure between different neurons, proteins or species influences the functioning of their respective systems. It is well-established that many biological networks are constructed in a highly hierarchical way with two main properties: short average paths that join two apparently distant nodes (neuronal, species, or protein patches) and a high proportion of nodes in modular aggregations. Although several hypotheses have been proposed so far, still little is known about the relation of the modules with the dynamical activity in such biological systems. Here we show that network modularity is a key ingredient for the formation of self-organising patterns of functional activity, independently of the topological peculiarities of the structure of the modules. In particular, we propose a self-organising mechanism which explains the formation of macroscopic spatial patterns, which are homogeneous within modules. This may explain how spontaneous order in biological networks follows their modular structural organisation. We test our results on real-world networks to confirm the important role of modularity in creating macro-scale patterns.

WORK LIFE BALANCE OF EMPLOYEES IN MID-SIZE INDUSTRIES EMPLOYEES

description: Work life balance is a concept which helps in giving priority to the work and life. The work life balance varies for each individual, at all times. The right balance will be different for a single person and a married person, for a fresher and an experienced worker. Referring to emotional labor theory, this paper examines these interconnections by conducting a three-phase empirical study in the Mid-size manufacturing industry. Results of the first study reveal that employees’ positive emotion display and emotional dissonance negatively influence employees’ work-life balance which in turn drives employees’ affective commitment. Results of the second study confirm emotional labor’s impact on their work-life balance perception. Conversely, job satisfaction is solely influenced by emotional dissonance. Work-life balance and job satisfaction further drive employees’ commitment. Results of the third study partially replicate these results: Emotional labor negatively impacts on employees’ work-life balance and job satisfaction which both drive their commitment.

WOMEN, COMPUTERS, AND INFORMATION WORK
Creators: name: Kraft, Joan Federico
Publisher: name: American University
Year: 2023

description: This research studies information work, the women who do it, and how computers are changing that work. The research questions are: how are the information sector and information work (work that produces information, rather than goods, food, or non-information services) growing; how is the adoption of micro-computers changing that work in terms of employment, shifts in work, and sex segregation; and how are that growth and change affecting women and men differently?; Occupation and industry data from the Current Population Survey for the years 1974 to 1986 are compared to data on computer sales. Workers are classified as information workers using a scheme developed by Uri Porat. It is found that in 1986, 48 percent of all employed persons did information work. Information work differs from all other forms of work studied in its constant growth. Recognition of this fact would be an aid in employment projections. Women are the main beneficiaries of that growth, obtaining three fourths of new information employment. Consequently, they are increasing rapidly as a percent of information workers. Women depend on this work, as 59 percent of employed women do information work, compared to 39 percent of employed men. Women and men are segregated by type of information work. Men primarily produce new information, plan and control, and do market search and coordination. Women distribute and process information. The adoption of micro-computers has not decreased information work nor slowed its growth. However, this adoption is associated with a shift in work, as the percent of clerical workers decreases, while that of managers increases, implying lessened need for information processing and greater need for control. Computerization may also lead to decreases in employment in some professional work. Micro-computers are associated with increases in employment for women, in spite of the fact that it is the traditionally male dominated occupational groups that grow. Computerization is also accompanied by a more rapid decrease in sex segregation. Contrary to expectations, women are benefiting from this new technology, perhaps at the expense of creating deeper divisions between women.

description: A sample of 27 Planetary Nebulae (PNs) in the Small Magellanic Clouds (SMC) have been observed with the Hubble Space Telescope Imaging Spectrograph (HST/STIS) to determine their morphology, size, and the spatial variation of the ratios of bright emission lines. The morphologies of SMC PNs are similar to those of LMC and Galactic PNs. However, only a third of the resolved SMC PNs are asymmetric, compared to half in the LMC. The low metallicity environment of the SMC seems to discourage the onset of bipolarity in PNs. We measured the line intensity, average surface brightness (SB), and photometric radius of each nebula in halpha, hbeta, [O III] lambda4959 and 5007, [NII] 6548 and 6584, [S II] lambda6716 and 5731, He I 6678, and [OI] 6300 and 6363. We show that the surface brightness to radius relationship is the same as in LMC PNs, indicating its possible use as a distance scale indicator for Galactic PNs. We determine the electron densities and the ionized masses of the nebulae where the [S II] lines were measured accurately, and we find that the SMC PNs are denser than the LMC PNs by a factor of 1.5. The average ionized mass of the SMC PNs is 0.3 Msun. We also found that the median [O III]/hbeta intensity ratio in the SMC is about half than the corresponding LMC median. We use Cloudy to model the dependence of the [O III]/hbeta ratio on the oxygen abundance. Our models encompass very well the average observed physical quantities. We suggest that the SMC PNs are principally cooled by the carbon lines, making it hard to study their excitation based on the optical lines at our disposal.

description: Large-scale collective behavior in suspensions of many particles can be understood from the balance of statistical forces emerging beyond the direct microscopic particle interactions. Here we review some aspects of the collective forces that can arise in suspensions of self-propelled active Brownian particles: wall forces under confinement, interfacial forces, and forces on immersed bodies mediated by the suspension. Even for non-aligning active particles, these forces are intimately related to a non-uniform polarization of particle orientations induced by walls and bodies, or inhomogeneous density profiles. We conclude by pointing out future directions and promising areas for the application of collective forces in synthetic active matter, as well as their role in living active matter.

description: Deep Neural Networks (DNNs) have been traditionally designed by human experts in a painstaking and expensive process, dubbed by many researchers to be more of an art than science. However, the ever increasing demand for state-of-the-art performance and real-world deployment has resulted in larger models, making the manual DNN design a daunting task. AutoML presents a promising path towards
alleviating this engineering burden by automatically identifying the DNN hyperparameters, such as the
number of layers or the type of layer-wise operations. As modern DNNs grow larger, AutoML methods face two key challenges: first, the increased DNN model sizes result in increased computational complexity during inference, making it difficult to deploy AutoML-designed DNNs to resource-constrained devices. Second, due to the large DNN design space, each AutoML search remains considerably costly, with an overall cost of hundreds of GPU-hours. In this thesis, we propose AutoML methods that are both hardware aware and search-cost efficient. We
introduce a Bayesian optimization (BO) methodology enhanced with hardware-cost predictive models, allowing the AutoML search to traverse the design space in a constraint “complying” manner, up to 3.5? faster compared to vanilla BO methods. Moreover, we formulate the design of adaptive DNNs as an AutoML task and we jointly solve for the DNN architectures and the adaptive execution scheme, reducing energy consumption by up to 6? compared to hand-tuned designs. Next, in a departure from existing one-shot
Neural Architecture Search (NAS) assumptions on how the candidate DNN architectures are evaluated, we introduce a novel view of the one-shot NAS problem as finding the subsets of kernel weights across a single-path one-shot model. Our proposed formulation reduces the NAS search cost by up to 5,000? compared to existing NAS methods. Taking advantage of such efficiency, we investigate how various design space and formulation choices affect the AutoML results, achieving a new state-of-the-art NAS
performance for image classification accuracy (75.62%) under runtime constraints on mobile devices.

description: We study Born-Infeld type tachyonic effective action of unstable D2-brane with a runaway potential and find rich structure of static regular solitonic solutions. There exists only periodic array of tachyon kink-antikinks in pure tachyonic theory, however, in the presence of electromagnetic fields, solutions include periodic arrays, topological tachyon kinks, half kink, and bounces. Computed tension of each kink or single unit of the periodic array has $T_{1}=\sqrt{2}πT_{2}$ or that with a multiplicative factor depending on electric field. When both electric and magnetic fields are turned on, fundamental string charge density has a confined component in addition to a constant piece. These evidences imply that the obtained codimension-1 objects are likely to be interpreted as D1-brane (and D1F1) or array of D1$\bar{\rm D}1$ (and D1F1-$\bar{\rm D}1$F1) as was the case without the electromagnetic fields. Generalization to unstable D$p$-branes is straightforward.

description: This research studies information work, the women who do it, and how computers are changing that work. The research questions are: how are the information sector and information work (work that produces information, rather than goods, food, or non-information services) growing; how is the adoption of micro-computers changing that work in terms of employment, shifts in work, and sex segregation; and how are that growth and change affecting women and men differently?; Occupation and industry data from the Current Population Survey for the years 1974 to 1986 are compared to data on computer sales. Workers are classified as information workers using a scheme developed by Uri Porat. It is found that in 1986, 48 percent of all employed persons did information work. Information work differs from all other forms of work studied in its constant growth. Recognition of this fact would be an aid in employment projections. Women are the main beneficiaries of that growth, obtaining three fourths of new information employment. Consequently, they are increasing rapidly as a percent of information workers. Women depend on this work, as 59 percent of employed women do information work, compared to 39 percent of employed men. Women and men are segregated by type of information work. Men primarily produce new information, plan and control, and do market search and coordination. Women distribute and process information. The adoption of micro-computers has not decreased information work nor slowed its growth. However, this adoption is associated with a shift in work, as the percent of clerical workers decreases, while that of managers increases, implying lessened need for information processing and greater need for control. Computerization may also lead to decreases in employment in some professional work. Micro-computers are associated with increases in employment for women, in spite of the fact that it is the traditionally male dominated occupational groups that grow. Computerization is also accompanied by a more rapid decrease in sex segregation. Contrary to expectations, women are benefiting from this new technology, perhaps at the expense of creating deeper divisions between women.

description: We present a time-lapse sequence of 20 near-infrared (J- and K'-band) snapshots of the central 20x20 arcsec of the Crab pulsar wind nebula, taken at subarcsecond resolution with the Hokupa'a/QUIRC adaptive optics camera on the Gemini North Telescope, and sampled at intervals of 10 min and 24 hr. It is observed that the equatorial wisps and polar knots in the termination shock of the pulsar wind appear to fluctuate in brightness on kilosecond time-scales. Maximum flux variations of +/-24 +/-4 and +/-14 +/-4 per cent relative to the mean (in 1.2 ks) are measured for the wisps and knots respectively, with greatest statistical significance in J band where the nebula background is less prominent. The J and K' flux densities imply different near-infrared spectra for the nonthermal continuum emission from the wisps and outermost polar knot (sprite), giving F_nu ~ nu^{-0.56+/-0.12} and F_nu ~ nu^{-0.21+/-0.13) respectively. The data are compared with existing optical and UV photometry and applied to constrain theories of the variability of the wisps (relativistic ion-cyclotron instability) and knots (relativistic fire hose instability).

description: In behavioral economics, human decision makers are modeled as anticipatory agents that make decisions by taking into account the probability of future decisions (plans). We consider cyber-physical systems involving the interaction between anticipatory agents and statistical detection. A sensing device records the decisions of an anticipatory agent. Given these decisions, how can the sensing device achieve quickest detection of a change in the anticipatory system? From a decision theoretic point of view, anticipatory models are time inconsistent meaning that Bellman's principle of optimality does not hold. The appropriate formalism is the subgame Nash equilibrium. We show that the interaction between anticipatory agents and sequential quickest detection results in unusual (nonconvex) structure of the quickest change detection policy. Our methodology yields a useful framework for situation awareness systems and anticipatory human decision makers interacting with sequential detectors.
