Abstract While we know that poor decisions during concept screening can lead to great expenses including redesign costs, production postponement, and even product failure, little is known about what factors influence professional concept screening. Previous research in this area has mostly been conducted with students or used hypothetical design challenges with professionals. This is problematic because such research methods are based on challengeable assumptions leaving out the risks and consequences that professionals face in their daily work. Hence, the purpose of the current study was to investigate the process of professionals making screening decisions in situ and identify the impact of the perceived properties of ideas (i.e., riskiness, originality, and feasibility) and the role of the professionals (idea generators versus executives) in this process. Specifically, a mixed method in-situ study was conducted in a small electromechanical company which included shadowing a research and development team from the conceptual stage to a final pitch meeting to senior executives. In addition, surveys and interviews were conducted to identify what factors were impacting concept screening. The results showed both idea generators and executives were able to distinguish and move ideas with relatively high market potential forward and avoided taking risks during concept screening. However, the idea generators did not show any preferences on the originality or feasibility of the ideas, while the executives preferred to invest in ideas with high feasibility. The findings of this study drew a distinction between professional design studies solving real design problems in a naturalistic, collocated team environment and those in a laboratory setting and added to the understanding of factors that influence the decisions made during professional concept screening. They also provide a much-needed insight into how engineering design professionals screen ideas.

The research investigates the role of service design and improvisation as decolonising practice. It is based on case study research with a focus group consisting of Namibian artists, designers, artisans and arts organisations who participated in artistic and cultural exchange activities of the Art South-South Trust (ASST), a start-up Namibian not for profit (NFP) organisation. The goal of ASST was to increase visibility of the focus group members, enable global exposure and create an arena for multi-vocality. The paper creates a practical framework for decolonising practices in Namibian arts and design by drawing on reflective practice to analyse the activities of ASST alongside interview data collected from Namibian and Australian partner organisations and participants in the program. Critical thinking is used to evaluate the impact of realised activities and processes both in situ in Namibia and in exchange in Australia. This paper explores practices that can enable decolonising processes in Namibian arts and design spheres

The objective of this study was to measure the level of cruise tourists' satisfaction as well as the relationship between satisfaction, recommendation, return intention, and expenditure. Also, the impact of factors such as nationality, length of the visit, and age on the level of expenditure was measured. An empirical approach for data collection was followed and a total of 152 questionnaires were collected from cruise tourists visiting the capital city of Oman, Muscat, as cruise liners anchor at Sultan Qaboos Port. Results of the regression analysis supported the existence of a causal relationship between satisfaction with destination attributes, overall satisfaction, recommendation, return intention, and expenditure. It was found that the average expenditure varies according to age and length of the visit. Recommendations for policy makers were suggested on how to increase the role of cruise tourism in strengthening the economy.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

Abstract Objective To evaluate the impact of preoperative MRI in the management of Ductal carcinoma in situ (DCIS). Methods We searched the PubMed, EMBASE and Cochrane Library databases to identify randomised clinical trials (RCTs) or cohort studies assessing the impact of preoperative breast MRI in surgical outcomes, treatment change or loco-regional recurrence. We provided pooled estimates for odds ratios (OR), relative risks (RR) and proportions and assessed the certainty of the evidence using the GRADE approach. Results We included 3 RCTs and 23 observational cohorts, corresponding to 20,415 patients. For initial breast-conserving surgery (BCS), the RCTs showed that MRI may result in little to no difference (RR 0.95, 95% CI 0.90 to 1.00) (low certainty); observational studies showed that MRI may have no difference in the odds of re-operation after BCS (OR 0.96; 95% CI 0.36 to 2.61) (low certainty); and uncertain evidence from RCTs suggests little to no difference with respect to total mastectomy rate (RR 0.91; 95% CI 0.65 to 1.27) (very low certainty). We also found that MRI may change the initial treatment plans in 17% (95% CI 12 to 24%) of cases, but with little to no effect on locoregional recurrence (aHR = 1.18; 95% CI 0.79 to 1.76) (very low certainty). Conclusion We found evidence of low to very low certainty which may suggest there is no improvement of surgical outcomes with pre-operative MRI assessment of women with DCIS lesions. There is a need for large rigorously conducted RCTs to evaluate the role of preoperative MRI in this population. Key Points • Evidence of low to very low certainty may suggest there is no improvement in surgical outcomes with pre-operative MRI. • There is a need for large rigorously conducted RCTs evaluating the role of preoperative MRI to improve treatment planning for DCIS.

Background: Men who develop behaviors connected with the model of hegemonic masculinity present several health problems. Previous research has shown the types of problems that men commonly suffer in this regard such as chronic diseases, dietary disorders, and traffic accidents. To combat and overcome this situation, several campaigns, policies and recommendations have been undertaken, and consequently, their influence has been analyzed. However, there have been few investigations into the role of men’s friendship in the reduction of these physical health problems. The findings presented in this article are focused on this issue, illustrating the impact of male friendship on the shaping of healthy behaviors. Methods: Drawing upon a qualitative-based methodology articulated in a case study of the Men in Dialogue association, located in Spain, the study has followed the premises of the communicative approach, a total of 15 structured online open-ended questionnaires have been performed and analyzed. The median age of the participants is 37.5 years. Results: The findings show how men involved in Men in Dialogue are promoting a kind of masculine friendship that is improving men’s emotional well-being and, consequently, their physical health.

AbstractWe present and discuss the role of nanoparticles size and stoichiometry over the local atomic environment of nanostructured VOx films. The samples have been characterized in situ using X-ray absorption near-edge structure (XANES) spectroscopy identifying the stoichiometry-dependent fingerprints of disordered atomic arrangement. In vanadium oxides, the ligand atoms arrange according to a distorted octahedral geometry depending on the oxidation state, e.g. trigonal distortion in V2O3 and tetragonal distortion in bulk VO2. We demonstrate, taking VO2 as a case study, that as a consequence of the nanometric size of the nanoparticles, the original ligands symmetry of the bulk is broken resulting in the coexistence of a continuum of distorted atomic conformations. The resulting modulation of the electronic structure of the nanostructured VOx as a function of the oxygen content reveals a stoichiometry-dependent increase of disorder in the ligands matrix. This work shows the possibility to produce VOx nanostructured films accessing new disordered phases and provides a unique tool to investigate the complex matter.

PurposeThe purpose of this research is to explore the combining of marketing and organizational literature. This paper seeks to evaluate the relationships between multichannel coordination and customer participation, as seen through the lens of potential customer opportunism. It aims at showing the impact of this opportunism on the organizational design of multiple channels structures.Design/methodology/approachThe research reports on an exploratory case study in a French retail bank. A total of 25 in‐depth interviews were conducted, and the use of other sources enabled data triangulation.FindingsThe results show first that an increase in the number of distribution channels is liable to favor customer opportunistic behavior. To counter this, the bank mainly relies on impersonal coordination modes. An emerging result highlights the role of the customer as a “perceptual filter” between the different channels of employees.Research limitations/implicationsCustomer opportunism is studied via channels employees perceptions. An investigation using a customer survey may help to better understand this construct, e.g. to identify its antecedents, and to measure it precisely. Moreover, further qualitative and/or quantitative studies with larger sample sizes are needed to try and generalize these results.Practical implicationsIt is recommended not to forget that customers can facilitate or hinder multichannel coordination. Retail banks have the power to use them conveniently, provided that they are fully conscious of the scope of the “partial employee” role played by the customer.Originality/valueThis paper broadens understanding of how multichannel distribution structures are coordinated, and in a way belies traditional organizational design literature. The emerging result gives birth to the concept of “reversed interactive marketing”, which has interesting theoretical and practical repercussions.

This paper addresses the problem of describing the spread of COVID-19 by a mathematical model introducing all the possible control actions as prevention (informative campaign, use of masks, social distancing, vaccination) and medication. The model adopted is similar to SEIQR, with the infected patients split into groups of asymptomatic subjects and isolated ones. This distinction is particularly important in the current pandemic, due to the fundamental the role of asymptomatic subjects in the virus diffusion. The influence of the control actions is considered in analysing the model, from the calculus of the equilibrium points to the determination of the reproduction number. This choice is motivated by the fact that the available organised data have been collected since from the end of February 2020, and almost simultaneously containment measures, increasing in typology and effectiveness, have been applied. The characteristics of COVID-19, not fully understood yet, suggest an asymmetric diffusion among countries and among categories of subjects. Referring to the Italian situation, the containment measures, as applied by the population, have been identified, showing their relation with the government's decisions; this allows the study of possible scenarios, comparing the impact of different possible choices.

The Tagueleft basin is geographically located in the northern edges of the Middle High Atlas, which is a geomorphological fragile area. The impact of human activity has accelerated water erosion in this mountains area. This is reflected in dynamic and unstable foothills, a decrease in forests density and degradation in the production of the land. On the other hand, land degradation due to human overexploitation of natural resources has increased land degradation in the area. The interest in the risk of erosion on the foothills in the area under study comes in the context of our contribution to clarify the role of geomatical and geomorphological approaches in explaining and identifying the mechanisms responsible for current foothills dynamism through water erosion and its negative impacts on the environment and local development. The aim of the study was to use the EPM (Erosion Potential Méthod) which is formulated by Slobodan Gavrilovic for erosion in mountainous areas and to test the reliability of its results based on fieldwork and remote sensing data. The results of the erosion assessment and its quantification by applying the coefficient (W) for the theoretical model in the area under study have shown that erosion is very important and it touches on wide areas as it appears through the domain classification of the distribution erosion in Tagueleft basin.
