SUMMARY Cortisol, androstenedione, testosterone, dehydroepiandrosterone sulphate (DHAS) and free (DHA) were measured in plasma of ten women affected by amenorrhoea with hyperprolactinaemia eleven secondary hypothalamic amenorrhoea; twelve normal at the second day menstrual cycle used as controls. All subjects hospitalized 17‐ketosteroids, 170H‐corticosteroids total also urine. Plasma DHAS was increased all hyperprolactinaemia, while DHA urinary significantly this group comparison to other...

Abstract This paper focuses on the implementation of circular economy (CE) practices in small‐ and medium‐sized firms all 28 European Union (EU) countries. The analyses take into account hierarchical nature collected data as are nested within EU countries, that is, heterogeneity between different types countries according to attitudes towards CE. multilevel latent class model identifies groups homogeneous terms CE, how enterprises (SMEs) distributed across These results, together with fact...

This study explored the size and potential of green employment for circular economy (CE) in small medium enterprises (SMEs) European Union, investigated role jobs skills implementation CE practices. The data were collected a Eurobarometer survey, refer to resource efficiency, markets, procedures. Lack environmental expertise is one factors that might be perceived as an obstacle when trying implement resource-efficiency actions. Previous research has shown that, although practices are adopted...

The scope of this paper is to analyze European consumers’ attitudes and behavior towards the environment. has following main objectives: measuring homogeneity heterogeneity within between countries with reference citizens’ involvement environmental issues, verifying relationship attitude behavior, identifying factors that might favor sustainable actions consumption. hierarchical nature data requires estimation multilevel models, specifically latent class models cluster citizens logistic...

ABSTRACT This paper studies the capital structure of businesses supported by microcredit based on pecking order theory (POT) using dynamic market segmentation. It analyses secondary data Crediamigo program. Then it estimates latent class Markov models to perform a segmentation customers. The indicate that business is in line with POT's principles due prioritizing equity when contracting loans. Furthermore, higher profit, lower debt. Distinct segments clients show different structures....

Cats are susceptible to feline panleukopenia virus (FPV) and canine parvovirus (CPV) variants 2a, 2b 2c. Detection of FPV CPV in apparently healthy cats their persistence white blood cells (WBC) other tissues when neutralising antibodies simultaneously present, suggest that may persist long-term the post-infection without causing clinical signs. The aim this study was screen a population 54 from Sardinia (Italy) for presence both DNA within buffy coat samples using polymerase chain reaction...

Conclusions about changes in categorical characteristics based on observed panel data can be incorrect when (even a small amount of) measurement error is present. Random errors, referred to as independent classification usually lead over-estimation of the total gross change, whereas systematic, correlated errors cause underestimation transitions. Furthermore, patterns true change may seriously distorted by or systematic errors. Latent class models and directed log-linear analysis are...

Spermatic and peripheral plasma concentrations of testosterone (T) androstenedione (A) have been measured in prepubertal boys affected by inguinal hernia (group I; n = 7) unilateral undescended testis II; 18). Mean (±SE) spermatic T (47.7 ± 14.8 ng/dl group 36.3 3.4 II) were significantly different from mean (9.8 ±2.1 9.3 0.9 both groups (P < 0.05 P 0.0005, respectively). A concentration (59.7 4.9 ng/dl) was higher than (49.8 II 0.05) but not I. values found I those II. The...

The aim of this paper is to develop an instrument measure customer satisfaction with reference the entire consumption experience experiential product, specific application cinema films. Experience defined as a new dimension product offer: combination goods and services enriched by sensations. Experiential marketing has innovative features, effects on all phases constituting experience. research looked for important aspects in process related means literature review exploratory survey. A list...

Abstract This paper examines the willingness of small and medium-sized enterprises (SMEs) in European Union (EU) to implement Circular Economy (CE) practices, i.e. re-planning use water reduce consumption maximize reuse, using renewable energy sources, its use, reducing waste by recycling or reusing selling it another company, redesigning products services materials recycled materials. These aspects are conceived as indicators CE which is explained factors at company country levels. The...

Measurement scales are a crucial instrument in marketing research for measuring unobservable variables such as attitudes, opinions and beliefs. In using, evaluating or developing multi-item scales, number of guidelines procedures recommended, to ensure that the measure applied is psychometrically robust. These have been outlined psychometric literature since late 1970s composed steps refer construct domain definition, scale validity, reliability, dimensionality generalisability. Various...

Purpose The purpose of the paper is analysis evolution students’ satisfaction over time in a large Italian university and effects on it because some characteristics teachers: didactic practices, beliefs needs with regard to teaching learning. Design/methodology/approach first step identifies latent construct, measured items composing questionnaire, proposes reduced set indicators measure model its (information collected three consecutive academic years available). A second clusters teachers...

Autism spectrum disorders (ASDs) impair many aspects of everyday life and may prevent access to dental care, often limiting it emergencies. Impaired oral health has long-lasting negative consequences on status the acquisition habits (e.g., respiration grinding) or competencies proper speech production). Children with ASD be scared in setting, which is rich sensory stimuli requires physical contact. Due their behavioral manifestations, they represent a challenge for dentists hygienists. We...

Practical schemes for distributed video coding with side information at the decoder need to consider non-standard correlation models in order take non-stationarities into account. In this paper we introduce two Gaussian sources, Gaussian- Bernoulli-Gaussian (GBG) and Gaussian-Erasure (GE) models, evaluate lower upper bounds on their rate-distortion functions. Provided that probability of impulse noise or erasures remains small, these remain close function correlation. Two practical GE model...

Abstract The Italian market of sparkling wines increases as volume and assortment (such brands, appellations, typologies) mainly because Prosecco consumption. We investigate the repeated purchase behavior in two years within supermarket channel through scanner data collected from a consumer panel. propose Hidden Markov Model to analyze these data, assuming an unobservable process capture consumers’ preferences allowing us consider purchases sparsity over time. multivariate responses defining...
