Toward a shared leadership environment: insights into retail salespeople’s work environment

Abstract The growing digitization puts more pressure on brick-and-mortar businesses in the retail sector by creating new and more complex customer demands that increase the need for cooperative and trustful exchange relationships between supervisors and salespeople. A promising approach to tackle these challenges lies in implementing less hierarchical leadership structures. While sharing leadership on the team level gains traction among practitioners as a viable form of horizontal leadership, research provides little evidence on the conditions and mechanisms that enable a shared leadership work environment for retail salespeople. Especially the role of formal leaders in such a transition remains unclear. To fill this void, we followed a two-study design. We conducted a large-scale survey with 1,527 salespeople of a German fashion retailer to analyze how formal leadership contributes to the existence of a less hierarchically structured work environment for retail salespeople. Our multiple mediation analysis provides in-depth and context-sensitive insights into conditions and mechanisms that facilitate a shared leadership environment. A subsequent online-based scenario experiment confirms that transformational leadership is a driver for a shared leadership environment. We contribute to the literature by showing that transformational leadership matters not only in business-to-business (B2B) settings but also in traditionally more transactional business-to-consumer (B2C) retail sales settings to create a shared leadership environment.
Secondary traumatic stress and posttraumatic growth among foster parents

ABSTRACT Using a cross-sectional survey design, this study aims to explore secondary traumatic stress (STS) and posttraumatic growth (PTG) among foster parents. Forty-six foster parents completed the Secondary Traumatic Stress Scale (STSS), the Posttraumatic Growth Inventory (PTGI), and a number of items representing demographics, foster parent experiences, and help-seeking. Multiple regression results indicate that both STS and PTG were higher among those who reported religious/spiritual help-seeking. In addition, STS was significantly higher among foster parents who were young and White. These results have implications for the future study of these concepts, which may prove useful in supporting foster parent well-being.
Low power design techniques for high speed pipelined ADCs

approved: Un-Ku Moon Pavan Kumar Hanumolu Real world is analog but the processing of signals can best be done in digital domain. So the need for Analog to Digital Converters(ADCs) is ever rising as more and more applications set in. With the advent of mobile technology, power in electronic equipment is being driven down to get more battery life. Because of their ubiquitous nature, ADCs are prime blocks in the signal chain in which power is intended to be reduced. In this thesis, four techniques to reduce power in high speed pipelined ADCs have been proposed. The first is a capacitor and opamp sharing technique that reduces the load on the first stage opamp by three fold. The second is a capacitor reset technique that aids removing the sample and hold block to reduce power. The third is a modified MDAC which can take rail-to-rail input swing to get an extra bit thus getting rid of a power hungry opamp. The fourth is a hybrid architecture which makes use of an asynchronous SAR ADC as the backend of a pipelined ADC to save power. Measurement and simulation results that prove the efficiency of the proposed techniques are presented. c Copyright by Naga Sasidhar January 12, 2009 All Rights Reserved Low Power Design Techniques for High Speed Pipelined ADCs
“In the Voices of People Like Me”: LGBTQ Coping During Trump’s Administration

The present study explored strategies that LGBTQ people used to cope during the U.S. presidential administration of Donald Trump. Coping strategies can buffer the impact of identity-related stigma and decreased psychological well-being, however, little is known about the ongoing coping strategies used by LGBTQ people during Trump’s presidential administration. This research addresses this gap in the literature. Participants included 335 LGBTQ individuals who were negatively impacted by the discriminatory policies of the Trump administration. Participants completed an online survey where they discussed the coping strategies they used during the Trump administration. Thematic analysis revealed five coping-related themes, including: (a) Coping Through Connecting With People, (b) Coping Through Self-Care and Self-Preservation Activities, (c) Coping Through Relational Disengagement, (d) Coping Through Activism, and (e) Coping Through Outness Decisions. Our discussion explores how counseling psychologists can work with LGBTQ clients to maximize coping strategies for managing distress during anti-LGBTQ presidential administrations.
Effect of Silymarin as an Adjunct Therapy in Combination with Sofosbuvir and Ribavirin in Hepatitis C Patients: A Miniature Clinical Trial

Silymarin is proclaimed to be a blend of flavonolignans or phytochemicals. An era of new generation of direct-acting antivirals (DAAs) has commenced to have facet effect in swaying of the hepatitis C virus (HCV). Nonetheless, this therapy has serious side effects that jeopardize its efficacy. This study is aimed at probing the effects of ribavirin (RBV) and sofosbuvir (SOF) along with silymarin as an adjunct therapy on hematological parameters and markers of obscured oxidative stress. The effect of DAAs along with silymarin was also examined on variable sex hormone level and liver function markers such as alanine aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and bilirubin. The study was followed to determine viral load and viral genotypes. A total of 30 patients were randomly divided into two equal groups comprising the control group (n = 15) and treatment group (n = 15). The control group was solely administered with DAAs (SOF and RBV; 400 mg/800 mg each/day). Conversely, the treatment group was dispensed with DAAs, but with adjunct therapy of silymarin (400 mg/day) along with DAAs (400/800 mg/day) over period of 8 weeks. Sampling of blood was performed at pre- and posttreatment levels for the evaluation of different propound parameters. Our data showed that silymarin adjunct therapy enhances the efficiency of DAAs. A decrease in menace level of liver markers such as ALT, ALP, AST, and bilirubin was observed (p > 0.05). The adjunct therapy concurrently also demonstrated an ameliorative effect on hematological indices and oxidative markers, for instance, SOD, TAS, GSH, GSSG, and MDA (p < 0.05), diminishing latent viral load. The silymarin administration was also found to revamp the fluster level of sex hormones. Our outcomes provide evidence that systematic administration of silymarin effectively remits deviant levels of hematological, serological, hormonal, and antioxidant markers. This demonstrates a possibly unique role of silymarin in mitigating hepatitis C.
Machine Learning in Point of Care Ultrasound

When a patient presents to the ED, clinicians often turn to medical imaging to better understand their condition. Traditionally, imaging is collected from the patient and interpreted by a radiologist remotely. However, scanning devices are increasingly equipped with analytical software that can provide quantitative assessments at the patient’s bedside. These assessments often rely on machine learning algorithms as a means of interpreting medical images.
The use of big data analytics to discover customers’ perceptions of and satisfaction with green hotel service quality

ABSTRACT This study examined customers’ green reviews on TripAdvisor and identified environmentally friendly themes and concepts. The differences among the 10 countries in terms of the volume of green reviews and customers’ green satisfaction ratings were also analysed. Using Leximancer analysis and multivariate analysis of a big dataset, we adopted a mixed research method to analyse 121,780 reviews posted on TripAdvisor for 87 green hotels from the top 10 tourism countries. The Leximancer analysis found that the most important themes mentioned in customers’ green reviews are room, daily, hotel, staff, front, food, coffee, amazing, experience, and trip. The results also showed that highest satisfaction ratings were ranked in Italy, the USA, and Turkey, respectively, while the lowest ratings were from Germany and France. The results provide critical recommendations for hoteliers to truly comprehend what green practices are noticed and appreciated by their customers.
Baseline characteristics of 32 patients with Gaucher disease who were treated with imiglucerase: South African data from the International Collaborative Gaucher Group (ICGG) Gaucher Registry.

BACKGROUND Gaucher disease (GD) is a rare inherited autosomal recessive metabolic disorder with a prevalence in the general population of ~1 per 100 000. To optimise the recognition, diagnosis and management of patients with GD in South Africa (SA), it is important to have an understanding of local patterns of presentation of the disease. OBJECTIVES To describe the baseline pretreatment characteristics of the SA cohort of patients enrolled into the International Collaborative Gaucher Group (ICGG) Gaucher Registry whowere treated with imiglucerase (Cerezyme; Sanofi Genzyme). METHODS The ICGG Gaucher Registry is an observational, longitudinal, international database that tracks the clinical, demographic, genetic, biochemical and therapeutic characteristics of patients with GD globally, irrespective of disease severity, treatment status or treatment choice. The study population included all SA patients reported in the ICGG Gaucher Registry as of 1 May 2020. RESULTS The registry included 49 SA GD patients, of whom 32 received imiglucerase as first primary GD therapy. All the patients had GD type 1, 59.4% were female, and mean and median ages at diagnosis were 14.7 and 9.8 years, respectively. The most common genotype was N370S/N370S (37.5%). At treatment initiation, 30.0% of patients had been splenectomised. Among patients for whom data were available, anaemia was present in one-third of non-splenectomised patients and 12.5% of those with splenectomy, and moderate or severe thrombocytopenia was reported in two-thirds of non-splenectomised patients. Bone pain was present in 30.8% and 57.1% of non- splenectomised and splenectomised patients, respectively. No bone crises were reported, and data relating to other bone complications were available for only ≤3 patients. CONCLUSIONS Haematological findings and bone pain in this group are similar to those in the global ICGG Gaucher Registry cohort. Lack of baseline data for other bone complications limits interpretation in that regard. Clinicians who treat patients with GD are encouraged to submit accurate, complete and up-to-date information so that comprehensive data for the subset of SA GD patients can be maintained to improve recognition and diagnosis, and guide appropriate and effective use of treatment for SA patients.
You are stuck here, at the office: Chilean ECEC principals’ pedagogical leadership in JUNJI and Integra Foundation

ABSTRACT This paper explores Chilean early childhood and care (ECEC) principals’ pedagogical leadership in the public sector, drawing upon literature regarding ECEC leadership. Following up a qualitative tradition, a purposive sample was used which considered 13 ECEC settings, from the 2 leading providers of public ECEC in Chile: JUNJI (the National Board of Nurseries for its acronym in Spanish) and Integra Foundation. Different techniques were used for data collection: semi-structured interviews with principals, ECEC teachers, teaching assistants, and parents. In addition, a shadowing technique was used to observe principals. Findings show that ECEC principals’ leadership is based on limited space to develop a pedagogical leadership due to a high administrative workload, alongside strong ethics of care fostered by principals, which are shared by the educational community – ECEC teachers, teaching assistants and families. We aim to generate knowledge about ECEC leadership for the Latin American context, particularly for the Chilean case, where we do not have any evidence about this topic.
Exploring regularity and structure in travel behavior using Smart Card data

As the economic opportunities fostered by large cities become more diverse, the travel patterns of public transport users become more heterogeneous. From personalized customer information, to improved travel demand models, understanding these heterogeneous travel patterns is useful for a number of applications relevant to public transport agencies. This thesis explores how smart card data can be used to analyze and compare the structure of individual travel patterns observed over several weeks. Specifically, the way in which multiple journeys and activities are ordered and combined into repeated patterns, both by the same individual over time and across individuals is evaluated from the journey sequence of each user. The research is structured around three objectives. First, we introduce a representation of individual travel patterns and develop a measure of travel sequence regularity. The mobility of each individual is modeled as a stochastic process with memory, of which each new realization represents an activity or journey. Entropy rate, a measure of randomness in the stochastic process, is used to quantify repetition in the order of journeys and activities. This analysis reveals that the order of events is an important component of regularity not explicitly captured in previous literature. Second, we develop an approach to identify clusters of travel patterns with similar structure considered with respect to public transport usage and activity patterns. Finally, we present an exploratory evaluation of the associations between the identified clusters and socio-demographic characteristics by linking smart card data to an annual travel diary survey. These three objectives are considered in the context of a practical application using the transactions of a sample of approximately 100,000 users collected between February 10 and March 1
Potential Role of Foliar Application of Azotobacter on Growth, Nutritional Value and Quality of Lettuce under Different Nitrogen Levels

Vegetables can be treated with biofertilizers as an alternative to chemical fertilizers because of their low toxicity. We investigated the effects of foliar spraying of Azotobacter under different levels of nitrogen (100, 150 and 200 mg/L in nutrient solution) on the growth, nutritional value, nitrate accumulation and antioxidant enzyme activities of hydroponically grown lettuce. The experiment was laid out in a completely randomized design with four replicates in a factorial combination. Plants treated with Azotobacter and 200 mg/L nitrogen had greater leaf area and photosynthetic pigments than plants treated with 200 mg/L nitrogen without spraying with Azotobacter. Increasing nitrogen levels increased leaf number, fresh and dry weights, leaf area and nitrate accumulation in lettuce plants. Peroxidase (POD) activity increased by 95.4% at a nitrogen level of 200 mg/L compared to a nitrogen level of 100 mg/L. Ascorbate peroxidase (APX) activity and leaf phosphorous (P) and potassium (K) concentrations were the highest in plants treated with a nitrogen source of 100 mg/L without foliar application of Azotobacter. As nitrogen levels increased in all treatments, nitrate reductase (NR) activity decreased and reached a minimum at the 200 mg/L nitrogen level. In general, foliar application of Azotobacter sp. can be used to promote plant growth and reduce nitrate accumulation in lettuce.
Association of the native parasitic nematode Deladenus proximus with individuals and populations of the native woodwasp Sirex nigricornis

Parasitic stages of the North American native dimorphic nematode Deladenus proximus develop within larvae of the native North American siricid Sirex nigricornis and sterilize many of the eggs in adult females. Sirex nigricornis were reared from felled trees or trapped in Arkansas and Louisiana in 2017–2019 and parasitism by D. proximus was evaluated. Deladenus proximus parasitized 0.16–0.43 of S. nigricornis individuals, among sites and years. Parasitized males were smaller than healthy males, and more males were parasitized than females emerging from the same trees. Rate of parasitism increased with increasing S. nigricornis density per tree, and, as per tree density increased, so did the proportion that was male. Egg sterilization (woodwasp eggs killed and inhabited by nematodes) was partial, with an average proportion of 0.66–0.88 woodwasp eggs sterilized by D. proximus per female S. nigricornis, differing significantly by site. As the numbers of eggs in a female increased, the proportion of eggs sterilized declined. Comparing data from this study with others, a trend is reported for variable levels of egg sterilization in Sirex females, with 0 or 100% sterilization often occurring in novel host/parasite associations and partial (averages between 50% and 100%) sterilization occurring when host/parasite associations have co‐evolved.
Clinical and Dermoscopic Approaches to Diagnosis of Frontal Fibrosing Alopecia: Results From a Multicenter Study of the International Dermoscopy Society

Introduction Frontal fibrosing alopecia (FFA) is a form of primary lymphocytic scarring alopecia characterized by a progressive recession of the fronto-temporal hairline. Although the clinical presentation of FFA is very typical, biopsy for histopathological examination is still recommended to confirm the diagnosis. Currently, a growing number of skin and mucosal inflammatory diseases are diagnosed with modern noninvasive techniques such as dermoscopy without the necessity of a biopsy. Objectives The International Dermoscopy Society (IDS) aimed to test the ability of its members to diagnose classic FFA through clinical and dermoscopic parameters and to compare acquired data to the largest cohort studies published since 1994. Methods This is an observational, cross-sectional study describing patient demographics, clinical presentation and diagnostic tools used in a sample of FFA patients collected by IDS members. A literature search was then performed using Pubmed to review studies reporting more than 100 cases. Results IDS members submitted 188 cases demonstrating a predominant female population (98.4%). In 71.8% of the cases, the clinical presentation and the trichoscopic findings allowed for the diagnosis. Out of 24 revised studies, 13 showed that clinical and trichoscopic features were decisive for the diagnosis in almost all cases. Conclusions Demographic and clinical data of our cohort were mostly comparable to previous reported data on FFA. The relevant role of the clinical and trichoscopic features in diagnosing FFA was confirmed by our study and the reviewed literature. Trichoscopy could be considered a worldwide-acknowledged non-invasive technique for the diagnosis of FFA.
Prioritising GDP or Tax Revenues: Indian Economists’ Dilemma

An efficient tax administration with fair tax rates is likely to generate substantial revenues, reducing the fiscal deficit, creating employments, and taming inflation. Indian tax administration has used the power to levitate tax as if it has been taken for granted by adopting the fixed money value target per geographical area instead of any data analytics. The effective tax rate and the average statutory tax rates were the highest in 2017–2018. Focus on generating non-tax revenues by multiple ways and structural reforms for boosting investments and household savings for accelerating GDP should be preferred over maximising tax revenues.
The nsp15 Nuclease as a Good Target to Combat SARS-CoV-2: Mechanism of Action and Its Inactivation with FDA-Approved Drugs

The pandemic caused by SARS-CoV-2 is not over yet, despite all the efforts from the scientific community. Vaccination is a crucial weapon to fight this virus; however, we still urge the development of antivirals to reduce the severity and progression of the COVID-19 disease. For that, a deep understanding of the mechanisms involved in viral replication is necessary. nsp15 is an endoribonuclease critical for the degradation of viral polyuridine sequences that activate host immune sensors. This enzyme is known as one of the major interferon antagonists from SARS-CoV-2. In this work, a biochemical characterization of SARS-CoV-2 nsp15 was performed. We saw that nsp15 is active as a hexamer, and zinc can block its activity. The role of conserved residues from SARS-CoV-2 nsp15 was investigated, and N164 was found to be important for protein hexamerization and to contribute to the specificity to degrade uridines. Several chemical groups that impact the activity of this ribonuclease were also identified. Additionally, FDA-approved drugs with the capacity to inhibit the in vitro activity of nsp15 are reported in this work. This study is of utmost importance by adding highly valuable information that can be used for the development and rational design of therapeutic strategies.
Analysis of factors influencing the qualitative characteristics of equine synovial fluid

The objective of the present study was to investigate the viscoelastic properties in synovial fluid between normal horses and horses with naturally occurring OA and to detect factors affecting synovial fluid viscosity. In total, 105 horses were included in this study. Synovial fluid samples were obtained from 60 mature horses with mild to moderate osteoarthritis in the 2nd interphalangeal, the metacarpophalangeal or the intercarpal joint. Forty-five horses were used as controls. Full rheological sample characterization was performed in order to measure the elastic G’ and viscous G’’ moduli. For determining hyaluronic acid concentrations a commercially available ELISA kit was used. The results of the linear mixed effect (LME) model revealed statistically significant (p < 0.001) effect of HA concentration, on the mean values of logG’ and logG” measurements. The ANOVA findings of the final model revealed statistically significant effect of joint type (p < 0.001) on the mean values of viscoelastic measurements. Interpreting the coefficients of the covariates osteoarthritis (p < 0.001) and age (p = 0.013), a negative correlation was detected on the response logG’ and logG” measurements. Geldings seemed to present lower viscous properties compared to mares. To the authors’ knowledge this is the first multivariate study to quantitatively evaluate the several factors that affect the viscoelastic properties of equine synovial fluid. Horses with osteoarthritis seemed to present lower viscoelastic properties compared to the healthy subjects that are joint type dependant. Finally, considering the multifactorial nature of osteoarthritis, one should expect an emerging need of personalized disease-modifying treatments.
