PurposeWhile remanufactured products represent an increasingly researched phenomenon in the literature, not much is known about consumers' understanding and acceptance of such products. This study ...explores this issue in the context of the theory of perceived risk (TPR), investigating return policy leniency and distribution channel choice as potential factors to foster remanufactured products' sales.Design/methodology/approachThis research utilizes an experimental design composed of a pre-test and a scenario-based main experiment to explore how return policy leniency might mitigate consumers' perceived risk and how their related purchase intention differs across two types of retail distribution channel structures (i.e. brick-and-mortar vs. online).FindingsThe investigation into the efficacy of return policy leniency within two retail distribution channel settings (i.e. brick-and-mortar vs. online) illustrates that providing a lenient return policy is an effective “cue” in increasing consumer purchase intention for remanufactured products. While prior literature has established that consumers value return policy leniency for new products, the authors provide empirical evidence that this preference also applies to remanufactured products. Notably, that return policy preference holds true in both channel settings (i.e. brick-and-mortar vs. online) under consideration. Additionally, and contrary to the authors’ predictions, consumers perceived remanufactured products sold via both channel settings as equally risky, thus highlighting that both are appropriate distribution channels for remanufactured products. Finally, while research on new products provides some initial guidance on consumer perceptions of quality and risk, the study provides empirical evidence into the difference of perceived risk with regard to new versus remanufactured products.Originality/valueBy employing the TPR, this research explored the role played by two supply chain management related factors (returns policy and channel structure) in reducing consumer's perceived risk and increasing purchase intention. In doing so, this study answers the call for more consumer-based supply chain management research in a controlled experimental research setting.
The present summary of the European Association of Urology (EAU) guidelines is based on the latest guidelines on male sexual health published in March 2021, with a last comprehensive update in ...January 2021.
To present a summary of the 2021 version of the EAU guidelines on sexual and reproductive health.
A literature review was performed up to January 2021. The guidelines were updated, and a strength rating for each recommendation was included based on either a systematic review of the evidence or a consensus opinion from the expert panel.
Late-onset hypogonadism is a clinical condition in the ageing male combining low levels of circulating testosterone and specific symptoms associated with impaired hormone production and/or action. A comprehensive diagnostic and therapeutic work-up, along with screening recommendations and contraindications, is provided. Erectile dysfunction (ED) is the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance. Along with a detailed basic and advanced diagnostic approach, a novel decision-making algorithm for treating ED in order to better tailor therapy to individual patients is provided. The EAU guidelines have adopted the definition of premature ejaculation (PE), which has been developed by the International Society for Sexual Medicine. After the subtype of PE has been defined, patient’s expectations should be discussed thoroughly and pharmacotherapy must be considered as the first-line treatment for patients with lifelong PE, whereas treating the underlying cause must be the initial goal for patients with acquired PE. Haemospermia is defined as the appearance of blood in the ejaculate. Several reasons of haemospermia have been acknowledged; the primary goal over the management work-up is to exclude malignant conditions and treat any other underlying cause.
The 2021 guidelines on sexual and reproductive health summarise the most recent findings, and advise in terms of diagnosis and treatment of male hypogonadism and sexual dysfunction for their use in clinical practice. These guidelines reflect the multidisciplinary nature of their management.
Updated European Association of Urology guidelines on sexual and reproductive health are presented, addressing the diagnosis and treatment of the most prevalent conditions in men. Patients must be fully informed of all relevant diagnostic and therapeutic options and, together with their treating physicians, decide on optimal personalised management strategies.
The 2021 guidelines on sexual and reproductive health provide a clinical framework for the diagnosis, and a multidisciplinary treatment approach of male hypogonadism and sexual dysfunction for use in clinical practice.

The European Association of Urology (EAU) has updated its guidelines on sexual and reproductive health for 2021.
To present a summary of the 2021 version of the EAU guidelines on sexual and ...reproductive health, including advances and areas of controversy in male infertility.
The panel performed a comprehensive literature review of novel data up to January 2021. The guidelines were updated and a strength rating for each recommendation was included that was based either on a systematic review of the literature or consensus opinion from the expert panel, where applicable.
The male partner in infertile couples should undergo a comprehensive urological assessment to identify and treat any modifiable risk factors causing fertility impairment. Infertile men are at a higher risk of harbouring and developing other diseases including malignancy and cardiovascular disease and should be screened for potential modifiable risk factors, such as hypogonadism. Sperm DNA fragmentation testing has emerged as a novel biomarker that can identify infertile men and provide information on the outcomes from assisted reproductive techniques. The role of hormone stimulation therapy in hypergonadotropic hypogonadal or eugonadal patients is controversial and is not recommended outside of clinical trials. Furthermore, there is insufficient evidence to support the widespread use of other empirical treatments and surgical interventions in clinical practice (such as antioxidants and surgical sperm retrieval in men without azoospermia). There is low-quality evidence to support the routine use of testicular fine-needle mapping as an alternative diagnostic and predictive tool before testicular sperm extraction (TESE) in men with nonobstructive azoospermia (NOA), and either conventional or microdissection TESE remains the surgical modality of choice for men with NOA.
All infertile men should undergo a comprehensive urological assessment to identify and treat any modifiable risk factors. Increasing data indicate that infertile men are at higher risk of cardiovascular mortality and of developing cancers and should be screened and counselled accordingly. There is low-quality evidence supporting the use of empirical treatments and interventions currently used in clinical practice; the efficacy of these therapies needs to be validated in large-scale randomised controlled trials.
Approximately 50% of infertility will be due to problems with the male partner. Therefore, all infertile men should be assessed by a specialist with the expertise to not only help optimise their fertility but also because they are at higher risk of developing cardiovascular disease and cancer long term and therefore require appropriate counselling and management. There are many treatments and interventions for male infertility that have not been validated in high-quality studies and caution should be applied to their use in routine clinical practice.
All infertile men require urological assessment and are at risk of cardiovascular mortality and several cancers. There is low-quality evidence supporting several empirical fertility treatments and the efficacy of these therapies needs to be validated in large-scale randomised controlled trials.

A variety of approaches are available to address a genital gender affirming surgery (GGAS) in transgender men. The aim of the present study is to report surgical and functional outcomes after a ...suprapubic pedicled phalloplasty (SPP). From November 2008 to August 2018, a consecutive series of 34 patients underwent an SPP in two tertiary referral centers. GGAS was conducted as a multistaged procedure, consisting (1) SPP with subsequent radial artery-based forearm free-flap urethroplasty, (2) glans sculpting, urethral anastomosis, and scrotoplasty, and (3) penile prosthesis implantation. The duration of surgery, intra and postoperative complications, and hospital stay were selected as variables for surgical outcomes. Functional outcomes were extrapolated from a four-item questionnaire.A partial necrosis of phallus was detected in two cases (5.8 %). Two cases of seroma formation with wound dehiscence (5.8%) were detected. Overall, 89% of patients declared to be fully satisfied of the SPP, 83% would recommend the procedure to someone else, and 89% would undergo the same procedure again. Overall, 66% of patients could achieve an orgasm during sexual penetrative intercourses. The retrospective design, the lack of randomization and validated questionnaire for outcomes reporting, and the limited follow-up represent the main drawbacks of our study. Our evidences suggest that SPP represents as an acceptable option for GGAS.

Synthetic Aperture Radar (SAR) imaging is starting to play an essential role in the automotive industry. Its day and night sensing capability, fine resolution, and high flexibility are key aspects ...making SAR a very compelling instrument in this field. This paper describes and compares three algorithms used to combine low-resolution images acquired by a Multiple-Input Multiple-Output (MIMO) automotive radar to form an SAR image of the environment. The first is the well-known Fast Factorized Back-Projection (FFBP), which focuses the image in different stages. The second one will be called 3D2D, and it is a simple 3D interpolation used to extract the SAR image from the Range-Angle-Velocity (RAV) data cube. The third will be called Quick&Dirty (Q&D), and it is a fast alternative to the 3D2D scheme that exploits the same intuition. A rigorous mathematical description of each algorithm is derived, and their limits are addressed. We then provide simulated results assessing different interpolation kernels, proving which one performs better. A rough estimation of the number of operations proves that both algorithms can be deployed using a real-time implementation. Finally, we will present some experimental results based on open road campaign data acquired using an eight-channel MIMO radar at 77 GHz, considering the case of a forward-looking geometry.

Recently more and more companies are adopting proactive sustainable strategies and developing sustainable supply chain management practices. Researchers identify Closed-Loop Supply Chain (CLSC) ...models as one of the major contributors to realising sustainable operations. Such models typically use flows concerning the products only as the unit of analysis.
This paper intends to provide a basis for developing new CLSC models, extending them to recovery resources from general outputs (e.g. unavoidable waste) with no value in terms of products. The new models affect also the configuration of the CLSC, with different set of resource suppliers and logistics providers.
The case study analysed in this paper derives from the food sector, in which the waste produced is reused as a resource, avoiding the disposal of different materials through resource-recovery activities that allow waste to be returned to the main supply chain as valuable inputs to configure a new supply chain.
The principal objective of this study is to create a new sustainable model of CLSC using and recovering waste from meat processing. A profitability indicator, an energy self-sufficiency one and a qualitative assessment of social implications are introduced to evaluate global sustainability opportunities for activating new loops.

In this paper, we discuss the possibility of generating high-resolution mapping of urban (or extra-urban) environments by the application of synthetic aperture radar (SAR) processing concepts to the ...data collected by mm-wave automotive radars installed on-board commercial vehicles. The study is motivated by the fact that radar sensors are becoming an indispensable component of the equipment of modern vehicles, being characterized by low cost, good performance, and affordable processing; therefore, in the future, nearly every single vehicle could be potentially equipped with radar devices capable of high-resolution imaging, enabled by application of SAR processing methodologies. Throughout this paper, we aim to discuss the role of SAR imaging in the automotive context under a theoretical and experimental perspective. First, we present the resulting benefits in terms of angular resolution and signal-to-noise ratio. Then, we discuss relevant technological aspects, such as suppression of angular ambiguities, fine estimation of platform motion, and SAR processing architectures, and we present a preliminary evaluation of the required computational costs. Finally, we will present a number of experimental results based on open road campaign data acquired using an 8-channel MIMO radar at 77 GHz, considering the cases of side-looking SAR, forward SAR, and SAR imaging of moving targets.

Purpose: To evaluate the impact of the COVID-19 pandemic lifestyle change on couples of reproductive age and on their desire for parenthood.
Materials and methods: A quantitative correlational ...research study, based on a web survey, was conducted among Italian men and women in heterosexual stable relationships, aged between 18 and 46 years. The self-administered Italian version questionnaire was created using Google Forms and posted on chats and social networks.The mood of participants before and during the quarantine was assessed using a scale from 1 to 10 (1 = no wellbeing; 10 = total wellbeing). Couples' quality of life and their reproductive desire were evaluated.
Results: 1482 respondents were included: 944 women (63.7%) and 538 men (36.3%). A significant trend toward reduced mean wellbeing scores during the quarantine, compared to before, was found (p < .01). From 18.1% participants who were planning to have a child before the pandemic, 37.3% abandoned the intention, related to worries of future economic difficulties (58%) and consequences on pregnancy (58%). Of 81.9% who did not intend to conceive, 11.5% revealed a desire for parenthood during quarantine than before (p < .01), related to will for change (50%) and need for positivity (40%). 4.3% of these actually tried to get pregnant. Stratifying by age, a trend toward older ages was found in the desire for parenthood before and during the COVID-19 pandemic (p < .05).
Conclusions: COVID-19 pandemic is impacting on the desire for parenthood. It is unknown whether these findings will result in a substantial modification of birth rate in the near future.
