Affiliation‐based hiring in startups and the origins of organizational diversity

Multiple imperatives call for more diversity in organizations, yet we know surprisingly little about why some organizations become more diverse than others. We focus on the early stages of organizations—the composition of founding teams (FTs) and the evolution of subsequent hiring practices, namely the prominence of finding new employees via founders’ prior employer and educational affiliations. Drawing upon theories of entrepreneurial resource mobilization and attraction–selection–attrition (ASA), we argue that FTs with common professional ties imprint post-founding hiring routines by making affiliation-based hiring (ABH) a more prominent practice to select new personnel. We posit that, although ABH fades quickly after founding, using this hiring strategy in the early stages of an organization shapes its trajectory for diversity and contributes to workforce homogenization in several dimensions as new firms mature. Using a mixed-methods approach combining large-scale employer–employee linked data from Denmark and in-depth surveys with founders from the US and UK, we find robust support for our theory and provide novel insights to the hiring processes in entrepreneurial firms. Our work advances our understanding of the enigmatic origins
Onthe changes in the physical properties of the ionized region around the Weigelt structures in η Carinae over the 5.54-yr spectroscopic cycle

We present HST/STIS observations and analysis of two prominent nebular structures around the central source of Eta Carinae, the knots C and D. The former is brighter than the latter for emission lines from intermediate or high ionization potential ions. The brightness of lines from intermediate and high ionization potential ions significantly decreases at phases around periastron. We do not see conspicuous changes in the brightness of lines from low ionization potential (<13.6 eV) that the total extinction towards the Weigelt structures is that the total extinction towards the Weigelt structures is AsubV =2/0. that the total extinction towards the Weigelt structures is AV = 2.0. Weigelt C and D are characterized by an electron density of that the total extinction towards the Weigelt structures is AV = 2.0. Weigelt C and D are characterized by an electron density of 10exp6.9 cm-3 that does not significantly change throughout the orbital cycle. The electron temperature varies from 5500 K (around periastron) to 7200 K (around apastron). The relative changes in the brightness of He I lines are well reproduced by the variations in the electron temperature alone. We found that, at phases around periastron, the electron temperature seems to be higher for Weigelt C than that of D. The Weigelt structures are located close to the Homunculus equatorial plane, at a distance of about 1240 AU from the central source. From the analysis of proper motion and age, the Weigelt complex can be associated with the equatorial structure called the Butterfly Nebula surrounding the central binary system.

Open Unemployment Rate and Poverty have no partial effect on Income Disparity in Riau Islands Province.
Improving Assimilation of Radiance Observations by Implementing Model Space Localization in an Ensemble Kalman Filter

Experiments using the National Oceanic and Atmospheric Administration Finite‐Volume Cubed‐Sphere Dynamical Core Global Forecasting System (FV3GFS) reveal that the four‐dimensional ensemble‐variational method (4DEnVAR) performs similarly to an ensemble Kalman filter (EnKF) when no radiance observations are assimilated, but 4DEnVAR is superior to an EnKF when radiance observations are assimilated. The hypothesis for the cause of the differences between 4DEnVAR and EnKF is the difference in vertical localization, since radiance observations are integral observations in the vertical and 4DEnVAR uses model space localization while the EnKF uses observation space localization. A modulation approach, which generates an expanded ensemble from the raw ensemble and eigenvectors of the localization matrix, has been adopted to implement model space localization in the operational National Oceanic and Atmospheric Administration EnKF. As constructed, the expanded ensemble is a square root of the vertically localized background error covariance matrix, so no explicit vertical localization is necessary during the EnKF update. The size of the expanded ensemble is proportional to the rank of the vertical localization matrix—for a vertical localization scale of 1.5 (3.0) scale heights, 12 (7) eigenvectors explain 96% of the variance of the localization matrix, so the expanded ensemble is 12 (7) times larger than the raw ensemble. Results from assimilating only radiance observations in the FV3GFS model confirm that EnKF with model‐space vertical localization performs better than observation‐space localization, and produces results similar to 4DEnVAR. Moreover, a 960‐member ensemble is sufficient to turn off the vertical localization entirely and yields significant improvements comparing to an 80‐member ensemble with model space localization.
Weighted Multiple Kernel Learning for Breast Cancer Diagnosis applied to Mammograms

Detecting breast cancer in mammograms can be a hard task even to most experienced specialists. Several works in the literature have tried to build models to describe malignant or benign findings using BI-RADS annotated features or features automatically extracted from images. Some of the best models are based on Support Vector Machines (SVMs). Features from mammograms have heterogeneous types and most methods handle them equally. Multiple Kernel Learning (MKL) can create models where each feature can be treated in a different way, which may improve the quality of the learned models. In this work, we use MKL to help building models to distinguish between malignant and benign findings. One of the problems with this domain is that the classes are unbalanced: fortunately the number of malignant cases is much smaller than the number of benign cases. However, this imbalance may lead an MKL classifier to label most of the cases as benign. We improve on these models by adopting a strategy of weighing the benign and malignant cases in order to produce models that are more reliable and robust to the class distribution. Our results show that our weighted approach produces better quality models for both balanced and unbalanced mammogram datasets.
Adaptive optics pre-correction demonstrator for terabit optical communication

For the next generation of very high throughput communication satellites, free-space optical (FSO) communication between ground stations and geostationary telecommunication satellites is a potential solution to overcome the limitations of RF links. To mitigate atmospheric turbulence effects, TNO proposes Adaptive Optics (AO) to apply uplink pre-correction. As a successor of Optics Feeder Link Adaptive Optics (OFELIA) breadboard [1], [2], the Terabit Optical Communication Adaptive Terminal (TOmCAT) project phase 2 aims to demonstrate the AO pre-correction technology for a terabit Optical Ground Station (OGT) in a ground-to-ground link field test over 10 km. Within this demonstrator an upgraded version of the OFELIA breadboard is used as optical bench for the AO (pre-)correction, but moreover the demonstrator enables the (future) integration of equipment for the final OGT configuration including the Beam Multiplexer (BMUX) and communication equipment. Apart from the OGT demonstrator, the overall layout of the field test has been upgraded, including the test site and the Ground Support Equipment (GSE), with the goal to create a better understanding of the encountered link phenomena and the instant (turbulence) conditions at which it was measured. New additions to the GSE are several weather stations placed along the link path to quantify the local turbulence and to relate the measured link performance to the instant turbulence conditions. The test campaign is split in two successive field tests: First the AO Demonstrator evaluates the upgraded AO pre-correction performance with a single non-modulated link, followed by the OGT Demonstrator which will include the multiplexing of multiple uplink channels and RF end-to-end modems to prove the technical feasibility of supporting a terabit communication link. This paper covers the design of the AO demonstrator and GSE, the field test layout and the preliminary results for the AO demonstrator field test. For the downlink correction the residual Wave Front Error (WFE) is presented. The pre-correction performance is depicted in the uplink transmission loss and scintillation, all as function of the encountered turbulence conditions.
The Mediating Role of Firm Prestige in the Relationship between Perceived Quality and Behaviour Intention in Customer Cafeteria Experiences

Customer experience is viewed from different perspectives as an economic, marketing, management, and competitive strategy. Regardless of the perspective, customer experience is a business strategy and a critical concept that plays a key role in firm success in the 21st century. In recent years, there has been an increasing focus on customer experience as a way for companies to differentiate themselves and build strong relationships with their customers. This approach is based on the idea that companies can build emotional bonds with their customers by providing memorable and positive experiences, leading to greater loyalty, repeat business and positive word-of-mouth. To create these experiences, companies adopt a customer-centric approach that involves understanding their customers’ needs, preferences and behaviours and using this information to design and deliver experiences that exceed their expectations. This approach requires moving away from traditional product-centric or sales-oriented strategies and instead places the customer at the centre of the company’s operations and decision-making processes. From a customer-centric perspective, meeting customer expectations in customer experiences is very important in shaping customer perceptions, attitudes and behaviours. From an experience-based perspective, a study was designed by taking into account the expectancy-affirmation theory, which is a psychological model that explains how customers evaluate their satisfaction with a product or service based on their expectations and perceptions of the experience, and a psychological theory that predicts that meeting customers’ expectations from their experiences may lead to a change in customer behaviour. The study examined the mediating role of firm prestige in the relationship between the perceived quality of customer experiences and customer behaviour intention. For this purpose, data were collected from 230 participants who had cafeteria experience through a questionnaire. The collected data were increased to 5000 by bootstrapping (derivative sampling) through the PLS-SEM algorithm. The study found that store prestige partially mediated the relationship between perceived experience quality and behavioural intention (customer satisfaction/loyalty) but did not mediate the relationship between food quality and behavioural intention (customer satisfaction/loyalty). The study also found that store prestige mediated the relationship between atmosphere quality and service quality, and behavioural intention (customer satisfaction/loyalty). Subsequently, cafeteria management policies should prioritise atmosphere and service quality. These factors directly impact the store’s prestige, leading to customer satisfaction and loyalty.
Comparison of Rescue Medication Prescriptions in Patients with Chronic Obstructive Pulmonary Disease Receiving Umeclidinium/Vilanterol versus Tiotropium Bromide/Olodaterol in Routine Clinical Practice in England

Purpose Routinely collected healthcare data on the comparative effectiveness of the long-acting muscarinic antagonist/long-acting β2-agonist combination umeclidinium/vilanterol (UMEC/VI) versus tiotropium bromide/olodaterol (TIO/OLO) for chronic obstructive pulmonary disease (COPD) is limited. This study compared rescue medication prescriptions in patients with COPD in England receiving UMEC/VI versus TIO/OLO. Patients and Methods This retrospective cohort study used primary care data from the Clinical Practice Research Datalink Aurum database linked with secondary care administrative data from Hospital Episode Statistics. Patients with a COPD diagnosis at age ≥35 years were included (indexed) following initiation of single-inhaler UMEC/VI or TIO/OLO between July 1, 2015, and September 30, 2019. Outcomes included the number of rescue medication prescriptions at 12-months (primary), and at 6-, 18- and 24-months (secondary), adherence at 6-, 12-, 18- and 24-months post-index, defined as proportion of days covered ≥80% (secondary), and time-to-initiation of triple therapy (exploratory). Inverse probability of treatment weighting (IPTW) was used to balance potential confounding baseline characteristics. Superiority of UMEC/VI versus TIO/OLO for the primary outcome of rescue medication prescriptions was assessed using an intention-to-treat analysis with a p-value < 0.05. Results In total, 8603 patients were eligible (UMEC/VI: n = 6536; TIO/OLO: n = 2067). Following IPTW, covariates were well balanced across groups. Patients initiating UMEC/VI had statistically significantly fewer (mean [standard deviation]; p-value) rescue medication prescriptions versus TIO/OLO in both the unweighted (4.84 [4.78] vs 5.68 [5.00]; p < 0.001) and weighted comparison (4.91 [4.81] vs 5.48 [5.02]; p = 0.0032) at 12 months; consistent results were seen at all timepoints. Adherence was numerically higher for TIO/OLO versus UMEC/VI at all timepoints. Time-to-triple therapy was similar between treatment groups. Conclusion UMEC/VI was superior to TIO/OLO in reducing rescue medication prescriptions at 12 months after treatment initiation in a primary care cohort in England, potentially suggesting improvements in symptom control with UMEC/VI compared with TIO/OLO.
The Role of Apical Periodontitis Disease in the Development of Bisphosphonate-Related Osteonecrosis of the Jaw: An Animal Study

Background: Microorganisms and their by-products are responsible for establishing pulpal and periapical diseases. Healing is compromised in patients under bisphosphonate therapy, and the presence of periapical infections can potentially lead to the development of medication-related osteonecrosis of the jaw (MRONJ). This work aimed to evaluate if bisphosphonate therapy is a risk factor for MRONJ development in the presence of periapical lesions. Methods: Two groups of 10 female Wistar rats were used. The experimental group received zoledronate (0.1 mg/kg) intraperitoneally, and the control received a saline solution, three times a week for three weeks. One week after the last injection, apical periodontitis was induced through pulpal exposure in the mandibular first molars. Twenty-one days later, the animals were intravenously injected with 99mTc-HMDP, and the radioactivity uptake by mandibular specimens was counted. In addition, sample radiographs and a histological examination were performed. Results: The bone loss was higher in the control group when compared to the experimental group (p = 0.027). 99mTc-HMDP uptake in the control was reduced compared with the experimental group, although without statistical significance. Conclusions: In the presence of zoledronate therapy, apical periodontitis does not increase the risk of MRONJ development, and periapical lesions have lower bone resorption when compared to the control group.

A Step Forward in the Characterization of Primary Brown Trout Hepatocytic Spheroids as Experimental Models

Simple Summary The liver is a vital organ for xenobiotic biotransformation and a prime target for drug toxicity. The search for alternative experimental liver models in fish and other species is critical to reducing the number of individuals used in animal experiments. Mammal liver spheroids have emerged as a viable in vitro model with similar morphofunctional properties to the liver. These three-dimensional (3D) structures are not well studied in fish. In this study, primary brown trout hepatocyte spheroids were characterised in biometry, histomorphology, and basal expression of a selection of target genes (metabolism and detoxification, efflux transport, and estrogenic signalling). The spheroids resembled in vivo liver features and demonstrated a morphological and functional time window stabilisation from the 12th to the 20th day in culture. The model is promising for investigating fish hepatic adaptive and toxicological responses to xenobiotics. Abstract Mammal hepatocyte spheroids have been investigated as alternative experimental models in several contexts, since three-dimensional (3D) systems have shown the potential to mimic in vivo scenarios. The description of fish hepatocyte 3D models is still minimal. This study intends to further characterize brown trout primary hepatocyte spheroids at distinct time points up to 25 days in culture. Viability, biometry, histomorphology, and basal expression of a selection of genes (metabolism and detoxification, efflux transport, and estrogenic signalling) were considered. The gene expression of whole liver samples from the same fish donor were evaluated concurrently. After 12 days in culture, the hepatocyte spheroids exhibited biometric and morphological stability. From the 12th to the 20th day in culture, the basal expression levels for most of the selected genes did not vary. The targeted mRNA levels were higher in brown trout liver samples compared to hepatocyte spheroids. Despite that, data supported that this model resembles some in vivo features. As an experimental alternative model, it showed potential to be used in a stable time window that can be exploited for exposure tests to different xenobiotics, namely, estrogenic compounds.
