Asymmetric Labor Adjustment, Organizational Capital and Aggregate Job Flows

This paper illustrates how the destruction of firm-specific organizational capital associated with changes in firm-level employment can influence the behavior of ag- gregate job flows, even in the presence of heterogeneity across rms and even in the absence of aggregate shocks. Our analysis highlights the potential importance of the distinction between adjustment costs that are associated with a loss of output (output-costs of labor adjustment) and those associated with a loss of organizational capital (OC-costs of labor adjustment). In particular, the analysis indicates how this link between organizational capital and labor demand can shape the behavior of net employment growth and gross job reallocation when conventional hiring and bring costs of adjustment may be unable to do so.

Sistem Pendukung Keputusan Tenaga Kesehatan Terbaik Menggunakan Metode Analytic Hierarchy Process (AHP) dan Simple Additive Weighting (SAW) (Studi Kasus Puskesmas Oesapa)

Puskesmas Oesapa memiliki peran penting dalam menyediakan pelayanan kesehatan berkualitas. Untuk meningkatkan kualitas layanan, terutama dalam memberikan pelayanan individu yang optimal, pemilihan tenaga kesehatan terbaik sangat penting. Penelitian ini mengembangkan Sistem Pendukung Keputusan (SPK) dengan metode Analytical Hierarchy Process (AHP) dan Simple Additive Weighting (SAW) untuk mengatasi masalah pemilihan tenaga kesehatan yang sebelumnya dilakukan secara manual. Metode AHP digunakan untuk menentukan bobot delapan kriteria penilaian, dan metode SAW untuk merangking tenaga kesehatan berdasarkan bobot tersebut. Implementasi sistem ini membantu kepala Puskesmas dalam mengambil keputusan yang lebih akurat dan objektif. Hasilnya, sistem mampu mengidentifikasi tenaga kesehatan terbaik, dengan Roselkrans sebagai penerima nilai tertinggi 0,913. Pengujian User Acceptance Test (UAT) menunjukkan tingkat kepuasan pengguna yang tinggi, dengan nilai fungsionalitas 94,33%, kegunaan 92,5%, keandalan 92%, dan efisiensi 92,5%, serta hasil pengujian blackbox mencapai 100%. Sistem ini diharapkan dapat meningkatkan objektivitas dan keadilan dalam penilaian tenaga kesehatan di Puskesmas Oesapa

Experimental Analysis and Modeling of Single-Sided vs Dual-Sided Filtering in Flex-Grid Switched Optical Networks

Flex-grid WSS filters embedded in Reconfigurable Add-Drop Multiplexers (ROADM) can selectively filter portions of the spectrum down to the GHz granularity enabling flexibility in optical channel add-drop operations. In this scenario, the signal's quality of transmission (QoT) can be severely impaired due to filters cascade by both single-sided (SS) and dualsided (DS) passband narrowing, due to filters' deviation from nominal frequency or multi-carrier transceivers switching. We experimentally observe lower penalties in the SS filtering case and their interplay w.r.t. ASE noise placement. We also propose an experimental calibration method able to directly estimate the overall signal QoT degradation suitable to integration in digital twins' lightpath computation engines and network planners

Experimental Validation of QoT Computation in Mixed 10G/100G Networks

We validate experimentally a quality-of-transmission estimator of the non-linear impairment on coherent 100G channels propagating with 10G channels on dispersion-managed links for network planning and path computation. Presented estimations are conservative, spectrally and spatially disaggregated

Real-time Detection of Anthropic Events by 10G Channels in Metro Network Segments

We present an experimental proof-of-concept on detecting SOP variations including information on mechanical stresses on the network footprint by tapping out a small amount of power from 10G channels. Data can be gathered and classified locally, in each node, delivering alerts through streaming telemetr

Spatially Disaggregated Modelling of Self-Channel NLI in Mixed Fibers Optical Transmission

We simulate and observe the buildup of coherency in self-channel interference. We propose a spatially disaggregated model for non-uniform links with uncompensated and compensated spans. We show that the correlation coefficient can be described by a unique curve

High Spectral Resolution Observations of the Massive Stars in the Galactic Center

We present high-resolution near-infrared spectra, obtained with the NIRSPEC spectrograph on the W. M. Keck II Telescope, of a collection of hot, massive stars within the central 25 arcseconds of the Galactic center. We have identified a total of twenty-one emission-line stars, seven of which are new radial velocity detections with five of those being classified as He I emission-line stars for the first time. These stars fall into two categories based on their spectral properties: 1) those with narrow 2.112, 2.113 micron He I doublet absorption lines, and 2) those with broad 2.058 micron He I emission lines. These data have the highest spectral resolution ever obtained for these sources and, as a result, both components of the absorption doublet are separately resolved for the first time. We use these spectral features to measure radial velocities. The majority of the measured radial velocities have relative errors of 20 kms, smaller than those previously obtained with proper-motion or radial velocity measurements for similar stellar samples in the Galactic center. The radial velocities estimated from the He I absorption doublet are more robust than those previously estimated from the 2.058 micron emission line, since they do not suffer from confusion due to emission from the surrounding ISM. Using this velocity information, we agree that the stars are orbiting in a somewhat coherent manner but are not as defined into a disk or disks as previously thought. Finally, multi-epoch radial velocity measurements for IRS 16NE show a change in its velocity presumably due to an unseen stellar companion.Comment: ApJ accepted, 42 pages, 16 figure

Monte Carlo of Trapped Ultracold Neutrons in the UCNτ Trap

In the UCNτ experiment, ultracold neutrons (UCN) are confined by magnetic fields and the Earth’s gravitational field. Field-trapping mitigates the problem of UCN loss on material surfaces, which caused the largest correction in prior neutron experiments using material bottles. However, the neutron dynamics in field traps differ qualitatively from those in material bottles. In the latter case, neutrons bounce off material surfaces with significant diffusivity and the population quickly reaches a static spatial distribution with a density gradient induced by the gravitational potential. In contrast, the field-confined UCN—whose dynamics can be described by Hamiltonian mechanics—do not exhibit the stochastic behaviors typical of an ideal gas model as observed in material bottles. In this report, we will describe our efforts to simulate UCN trapping in the UCNτ magneto-gravitational trap. We compare the simulation output to the experimental results to determine the parameters of the neutron detector and the input neutron distribution. The tuned model is then used to understand the phase space evolution of neutrons observed in the UCNτ experiment. We will discuss the implications of chaotic dynamics on controlling the systematic effects, such as spectral cleaning and microphonic heating, for a successful UCN lifetime experiment to reach a 0.01% level of precision

Setting and meeting priorities in Indigenous health research in Australia and its application in the Cooperative Research Centre for Aboriginal Health

Priority setting is about making decisions. Key issues faced during priority setting processes include identifying who makes these decisions, who sets the criteria, and who benefits. The paper reviews the literature and history around priority setting in research, particularly in Aboriginal health research. We explore these issues through a case study of the Cooperative Research Centre for Aboriginal Health (CRCAH)'s experience in setting and meeting priorities
