Bargaining with evolving private information

I study how the arrival of new private information affects bargaining outcomes. A seller makes offers to a buyer. The buyer is privately informed about her valuation and the seller privately observes her stochastically changing cost of delivering the good. Prices fall gradually at the early stages of negotiations, and trade is in-efﬁciently delayed. The ﬁrst-best is implementable via a mechanism, whereas all equilibrium outcomes of the bargaining game are inefﬁcient.
ORGANIZATIONAL CONFIGURATION AND THE DEVELOPMENT OF THE ABSORPTIVE CAPACITY: RELATIONS AND INFLUENCES

Objective: to analyze the existing relationships between typologies of organizational configurations with the development of absorptive capacity. Methodology: empirical research of an applied nature, Qualitative and descriptive approach. Data were collected through interviews with a structured script and analyzed using the content analysis technique. Originality: Offers explanations of how organizational settings influence the development of ACAP Main results: the simple structure configuration favors the recognition capacity and limits the assimilation and application capacity. The bureaucratic machine favors the capacity for recognition and assimilation, and limits application. Professional bureaucracy limits the capacity for recognition and application and favors assimilation. In the divided form, the capacity for recognition and assimilation is favored, and the capacity for application is limited. In adhocracy the ability of recognition, assimilation and application are favored. Theoretical contributions: the evidence indicates a fruitful and significant relationship between the constructs, a fact that allows us to understand the organizational configuration as an important antecedent of ACAP.
Deformations of Frozen Water Drops and Their Frequencies

Freezing experiments of freely falling water drops of diameter 45-765 *m were made by using a large cloud chamber 14.7 meters in height. Frequent shattering of freezing water drops is observed not only when water drops are nucleated by silver iodide in suspension but also when they are nucleated by collision with ice crystals after attaining thermal equilibrium with the environment. The frequency of shattering depends considerably on the nucleation temperature (Tn) and the drop size (d). The frequency of shattering is especially high in the size range d=75-135 *m when water drops are nucleated at temperatures between -14 and -20*C. Spikes are formed when water drops are nucleated at temperatures higher than the air temperature (Ta) and are scarcely formed when Tn*Ta. In the case of Ta*-27*C, the frequency of spike formation increases with the rise of the nucleation temperature and the increase of the drop size.
ENVIRONMENTAL AND INTERNAL FACTORS OF THE FIRM AND THE FINANCIAL PERFORMANCE OF COMPANIES: A LOOK AT COMPANIES LISTED ON B3 FROM THE PERSPECTIVE OF CORRUPTION AND POLITICAL-ECONOMIC STABILITY

Objective: to investigate the impact of corruption control and political-economic stability, combined with internal factors, defined by current liquidity, capital investments, size and debt, on the ROA, ROE and GI of publicly traded companies, listed on B3, in the period from 2011 to 2018. Methodology: multivariate regressions were applied with panel data using fixed effects on a sample of 270 publicly traded companies operating in B3 between 2011 and 2018. The sample considered annual, public data collected in the Economatica database. Originality: relatively few national studies dealt with the impact of corruption control mechanisms and political and economic stability on the financial performance of publicly traded Brazilian companies listed on B3. In addition, this work contributes as it seeks to expand the discussion on the analysis of business performance by incorporating an indicator of the companies' market value, defined by the degree of intangibility of the assets of the companies. Results: the corruption control mechanisms showed a positive correlation with the ROA and ROE, as expected, and a negative correlation with the GI, contrary to expectations, while the political and economic stability index, current liquidity, size and indebtedness were positively correlated with the ROA and ROE. Capital investments were not correlated with the financial performance of the companies studied. Theoretical contribution: to reinforce contemporary discussions on the influence of institutional factors, such as corruption and political and economic instability, and intra-firm factors, such as current liquidity, capital investments, size and indebtedness, in relation to economic-financial performance of companies, offering evidence for the formation of a theory capable of explaining the mechanisms of action of the perception of corruption and political-economic instability, together with microeconomic elements, on the performance of organizations.
Refractive trends in 15-year-old adolescents at optometric practices in southern Sweden between 2007 and 2020

The purpose of this study was to analyse the distribution of refractive errors in 15-year-old adolescents at optometric practices in southern Sweden between 2007 and 2020. Refractive data were collected retrospectively from clinical records in five optometric practices in southern Sweden. The inclusion criteria were individuals visiting the practice at an age of 15 years between 2007 and 2020. The refractive errors were classified by the spherical equivalent (SE) (sphere + 1⁄2 cylinder) as follows: myopia (SE ≤ -0.5 D), hyperopia (SE ≥ 0.5 D), emmetropia (-0.5 > SE < 0.5 D). The astigmatism axis (-1.5 DC) was analysed as with-the-rule, against-the-rule and oblique according to traditional methods. To examine trends, the average refraction and distribution of refractive errors were compared between two selected time periods, 2007–2013 and 2014–2020. During the time frame 500 adolescents aged 15 years were examined in the selected optometric practices. Myopia was found in 34%, emmetropia in 35% and hyperopia in 31%. Among 37 individuals with astigmatism, the most common axis was with- the-rule (41%), followed by oblique (32%) and against-the-rule (27%). No significant differences could be found in the distribution of different refractive errors between the periods 2007–2013 and 2014–2020. Nor could any significant difference in average refraction be found. In contrast to the expected global rise in myopia as predicted by WHO and the high prevalence of myopia reported in some parts of the world, we could not find convincing changes in distribution between myopia and hyperopia in this cohort of Swedish adolescents.
INNOVAZIONE E RICERCA PER LE INDUSTRIE

In this study, the composition of phytosterols, tocopherols and triterpenoids from four Tunisian grape seed oil varieties (Razagui, Marsaoui, Muscat d’Alexandrie and Khamri) was determined. GC-MS analysis allowed the identification of one triterpenic compound (β-amyrin), five phytosterols (campesterol, stigmasterol, β-sitosterol, β-sitostanol, cholesterol) and three tocopherols isoforms (α, β and γ-tocopherols). Furthermore, grape seed oils had potent antioxidant activities using DPPH and chelating iron assays. Multivariate analysis and principal component analysis (PCA), based on compounds profiling data and chemotypes found in this fraction, revealed distinguished groups of varieties associated to specific composition patterns.
Foreign Direct Investment, Geography, and Welfare∗

We study the impact of FDI on domestic welfare using a model of internal trade with variable markups. The model allows us to disentangle the various channels through which FDI affects welfare. We apply the model to study the case of Ethiopian manufacturing, which received substantial amounts of FDI during the period that we study. We find substantial gains from the presence of foreign firms. FDI, however, resulted in a modest worsening of allocative efficiency because foreign firms tend to have significantly higher markups than domestic firms. We additionally conduct empirical analysis that are consistent with these findings. This empirical analysis makes use of microdata on manufacturing firms, information on FDI projects, and geospatial data on improvements in the road network. ∗The views expressed in this paper are of the authors and do not reflect the views of the U.S. Census Bureau.

CPAP Compliance in Sleep Apnea Patients with and without Laboratory CPAP Titration

Advances in auto-adjusting positive airway pressure technology for obstructive sleep apnea now permit this treatment to be initiated outside of the sleep laboratory environment, bypassing the need for laboratory-based titration studies. Thus far, little research has addressed how such developments may affect compliance to continuous positive airway pressure (CPAP). We tested the effect of laboratory CPAP exposure and technologist support in a retrospective chart review of 98 veterans with obstructive sleep apnea to determine whether patients who received standard laboratory CPAP titration complied better with CPAP than did patients who received no laboratory CPAP titration. Fifty patients underwent standard technician-attended polysomnography (PSG) with CPAP titration, and 48 patients underwent unattended PSG with no laboratory trial of CPAP (ﬁrst CPAP exposure was at home). Objective CPAP compliance measures were obtained from CPAP units at follow-up visits. Attended-PSG patients wore CPAP signiﬁcantly longer per night on average (5.0 hours vs 3.9 hours) and tended to wear CPAP on more nights (76.5% vs 64.2%) compared with unattended-PSG patients. These ﬁndings suggest that patients’ sleep laboratory experience with CPAP and the support and education provided by sleep technologists are important factors in facilitating CPAP compliance.
Circuit Cavity Electromechanics in the Quantum Regime

Generating nonclassical states of a macroscopic mechanical object has been a subject of considerable interest. It offers a route toward fundamental test of quantum mechanics in an unexplored regime. However, a macroscopic quantum state is very susceptible to decoherence due to the environment. One way to generate robust quantum states is quantum reservoir engineering. In this work, we utilize the reservoir engineering scheme to generate a steady quantum squeezed state of a micron-scale mechanical oscillator in an electromechanical system. Together with the backaction evading measurement technique, we demonstrate a quantum nondemolition measurement of the mechanical quadratures to characterize the quantum squeezed state. By measuring the quadrature variances of the mechanical motion, more than 3dB squeezing below the zero-point level has been achieved.
Towards phase-coherent caloritronics in superconducting quantum circuits

The emerging field of coherent caloritronics (from the Latin word "calor", i.e., heat) is based on the possibility to manipulate the phase-coherent heat currents flowing in mesoscopic superconducting structures. The goal is to design and implement quantum technologies able to master energy transfer with the same degree of accuracy reached for charge transport in contemporary electronic devices. This can be obtained by exploiting the macroscopic quantum coherence intrinsic to superconducting condensates, which manifests itself through the Josephson and the proximity effect. Here, we review recent experimental results obtained in the realization of heat interferometers and thermal rectifiers, and discuss a few proposals for exotic non-linear phase-coherent caloritronic devices, such as thermal transistors, solid-state memories, coherent heat splitters, microwave refrigerators, thermal engines and heat valves. Besides being extremely attractive from the fundamental physics point of view, these systems are expected to have a vast impact on all cryogenic microcircuits requiring energy management, and (possibly) lay the first stone for the foundation of electronic thermal logic.
Bibliography on the Abraham-Minkowski Debate

In my present view, the Abraham-Minkowski debate is about how an electromechanical system can be partitioned into “electromagnetic” and “mechanical” subsystems. A view not taken by either Abraham or Minkowski is that the “electromagnetic” subsystem consists only of the (macroscopic or microscopic) fields E and B, and the polarization densities P and M are “mechanical” entities. Then, the density of momentum in the “electromagnetic field” is

Knowledge, Opinions, and Clinical Experience of General Practice Dentists toward Obstructive Sleep Apnea and Oral Appliances

Undiagnosed obstructive sleep apnea (OSA) can contribute to hypertension, cardiovascular disease, stroke, and detract from overall quality of life. Dentists can play an important role in detecting, making recommendations for, and treating OSA with oral appliances (OAs). A survey of 18 questions of knowledge and opinion of, educational background for, and clinical experience with OSA and OAs was mailed to 500 general practice dentists in Indiana, United States. Two hundred survey returns produced 192 valid responses. Responders reported strong positive opinions toward OSA and OAs. However, 58% of dentists could not identify common signs and symptoms of OSA, and 55% of dentists did not know the mechanism for mandibular advance devices. Only 39% of dentists could identify snoring, mild OSA, and intolerance to continuous positive airway pressure as possible indications for OA treatment. Respondents reported a general lack of education about both OSA and OAs. Only 31 (16%) were taught about this issue in dental school; 77 (40%) knew little or nothing about OA treatment for OSA patients; 57 (30%) learned from postgraduate training. Cooperation and referrals between dentists and physicians were rated as ‘‘poor. ’’ Of the responders, 54% never consulted with physicians for a suspected OSA patient in their practice; 75% of dentists reported they have never been referred patients by physicians; and 80% of dentists never or less than ﬁve times prescribed OAs to OSA patients. Results suggest a need for increased education and training regarding OSA and OAs in dental school, as well as increased cooperation between dentists and physicians for better patient care.

Cadaveric Dissections Based on Observations of Injuries to the Temporal Bone Structures following Head Trauma Commentary

One hundred temporal bones obtained from forensic autopsies were dissected to expose injured structures. Longitudinal fractures were present in 82%, transverse fractures in 11%, and mixed fractures in 7% of the cases. Facial canal injuries were present in almost half of the bones with longitudinal fractures (36/82), although cuts of the facial nerve stem were rarely encountered. Damages to the facial canal associated with longitudinal fractures were most frequently seen in the region of the geniculum. However, transverse fractures with facial canal involvement (7/11) most frequently occurred in the labyrinthine portion, causing a complete cut of the facial nerve. Injuries to the jugular bulb were also common (21/100) and associated with all types of temporal bone fractures. Observed damages to the auditory ossicles included disconnection of their joints or fractures of the malleus or stapes. Fractures of the incus were not observed. Injuries to the carotid canal were common (52/100), although an injury to the arterial wall was observed in only one specimen. The frequency and nature of damage in temporal bone fractures strictly reﬂect the type of fracture, especially in terms of facial nerve disorders: the most serious damage is observed with fractures that involve the otic capsule.
Instruments for Estimation of Health-Related Quality of Life in Patients with Skull Base Neoplasms

With advances in treatment of patients with tumors of the skull base and associated improvement in length of survival, the need for assessment of quality of life (QOL) is becoming increasingly apparent. A thorough assessment of QOL, including functional, physical, social, and emotional status, as well as disease-speciﬁc symptoms, allows for comparison of treatments and informs treatment decisions. In addition, it allows for problems following intervention to be identiﬁed and addressed, thereby assisting patients in their pursuits of returning to their normal activities and level of functioning. Although health care providers and researchers are increasingly aware of the need to assess patients’ QOL, few standardized measures exist with which to perform a comprehensive assessment of QOL in patients with skull base neoplasms. Further research is needed, including prospective trials using reliable and valid measures tapping various aspects of QOL and speciﬁc symptoms unique to patients with tumors of the skull base.
FULL-PHYSICS INVERSE LEARNING MACHINE FOR SATELLITE REMOTE SENSING OF OZONE PROFILE SHAPES AND TROPOSPHERIC COLUMNS

Abstract. Characterizing vertical distributions of ozone from nadir-viewing satellite measurements is known to be challenging, particularly the ozone information in the troposphere. A novel retrieval algorithm called Full-Physics Inverse Learning Machine (FP-ILM), has been developed at DLR in order to estimate ozone profile shapes based on machine learning techniques. In contrast to traditional inversion methods, the FP-ILM algorithm formulates the profile shape retrieval as a classification problem. Its implementation comprises a training phase to derive an inverse function from synthetic measurements, and an operational phase in which the inverse function is applied to real measurements. This paper extends the ability of the FP-ILM retrieval to derive tropospheric ozone columns from GOME- 2 measurements. Results of total and tropical tropospheric ozone columns are compared with the ones using the official GOME Data Processing (GDP) product and the convective-cloud-differential (CCD) method, respectively. Furthermore, the FP-ILM framework will be used for the near-real-time processing of the new European Sentinel sensors with their unprecedented spectral and spatial resolution and corresponding large increases in the amount of data.
Buoyancy-Induced Convection of Alumina-Water Nanofluids in Laterally Heated Vertical Slender Cavities

ABSTRACT A two-phase model based on the double-diffusive approach is used to perform a numerical study of natural convection of alumina-water nanofluids in differentially heated vertical slender cavities. In the mathematical formulation, Brownian diffusion and thermophoresis are assumed to be the only slip mechanisms by which the solid phase can develop a significant relative velocity with respect to the liquid phase. The system of the governing equations of continuity, momentum and energy for the nanofluid, and continuity for the nanoparticles is solved through a computational code relying on the SIMPLE-C algorithm for the pressure-velocity coupling. The effective thermal conductivity and dynamic viscosity of the nanofluid, and the coefficient of thermophoretic diffusion of the suspended solid phase, are evaluated using three empirical correlations based on a high number of experimental data available from diverse sources, and validated by way of literature data different from those used in generating them. Numerical simulations are executed for different height-to-width aspect ratios of the enclosure, as well as different average temperatures of the nanofluid. The heat transfer performance of the nanoparticle suspension relative to that of the base fluid is found to increase as the nanofluid average temperature is increased and, at low to moderate temperatures, the aspect ratio of the enclosure is decreased. Moreover, at temperatures higher than room temperature, a peak at an optimal particle loading is found to exist for any investigated configuration.
Comparison of Primary‐Care Practitioners and Sleep Specialists in the Treatment of Obstructive Sleep Apnea

We wished to determine if being treated for sleep apnea by a sleep specialist increased patient awareness or long-term continuous positive airway pressure (CPAP) compliance. We performed a retrospective telephone survey and laboratory chart review in patients with a diagnosis of sleep apnea evaluated either at a laboratory in which only sleep specialists can order polysomnography (University Specialty Hospital, noted as USH) or at a laboratory serving the medical community at large (Kernan Hospital, noted as K). Both laboratories are under the same medical director, use the same policies and procedures, equipment, and technician pool. One hundred three patients participated in the survey (approximately 37% of those contacted), 59 from USH and 44 from K. The groups were comparable in terms of demographics, presenting complaints, and apnea severity. In patients treated by sleep specialists, awareness of the disease process was greater and the evaluation was timelier than in patients treated by generalists. However, there was no difference between the groups’ long-term self-reported CPAP acceptance or compliance. The most robust predictor of continued CPAP use was the patient’s self-report of feeling better.
