LCA Circulaire Biopolymeren - PHA

Biopolymeren vormen een potentieel interessant alternatief voor conventioneel op olie gebaseerde polymeren, omdat zij geen fossiele grondstoffen gebruiken voor de productie. Daarentegen is het productie procedé afhankelijk van energie en toevoegmiddelen die weer bijdragen aan het verbruik van energie en de emissie van onder andere broeikasgassen en zijn de grondstoffen van belang, zoals het gebruik van reststromen uit de afvalverwerking of andere biomaterialen. Binnen het project Circulaire Biopolymeren Waardeketens zijn meerdere productiemethoden bestudeerd om polyhydroxyalkanoaten (PHAs) te maken uit organische reststromen: GFT en afvalwaterslib, een bijproduct uit de afvalwaterzuivering. Productie en extractie van PHAs kan middels diverse routes. In het project zijn meerdere extractieroutes bestudeerd betreffende hun mogelijkheden. Als onderdeel van het project is een levenscyclusanalyse (LCA) gedaan om de milieu-impact van de productie van de biopolymeren in kaart te brengen.

The economic impact of pilgrimage: an economic impact analysis of pilgrimage expenditures in Galicia

In this article, we calculate the economic impact of pilgrimage to Santiago de Compostela in the NUTS 2 region Galicia (Spain) in 2010. This economic impact is relevant to policymakers and other stakeholders dealing with religious tourism in Galicia. The analysis is based on the Input-Output model. Location Quotient formulas are used to derive the regional Input-Output table from the national Input-Output table of Spain. Both the Simple Location Quotient formula and Flegg's Location Quotient formula are applied. Furthermore, a sensitivity analysis is carried out. We found that pilgrimage expenditures in 2010 created between 59.750 million and 99.575 million in Gross Value Added and between 1, 362 and 2, 162 jobs. Most of the impact is generated within the 'Retail and Travel Services' industry, but also the 'Industry and Manufacturing', 'Services' and 'Financial and Real Estate Services' industries benefit from pilgrimage expenditures. This research indicates that in even in the most conservative scenario, the impact of pilgrimage is significant on the local economy of Galicia.

Reallocations in acne healthcare: exploring the possible roles and added value of nonphysicians by a mixed-methods study design

Background: A highly promoted opportunity for optimizing healthcare services is to expand the role of nonphysician care providers by care reallocation. Reallocating care from physicians to non-physicians can play an important role in solving systemic healthcare problems such as care delays, hospital overcrowding, long waiting lists, high work pressure and expanding healthcare costs. Dermatological healthcare services, such as the acne care provision, are well suited for exploring the opportunities for care reallocation as many different types of care professionals are involved in the care process. In the Netherlands, acne care is mainly delivered by general practitioners and dermatologists. The Dutch healthcare system also recognizes non-physician care providers, among which dermal therapists and beauticians are the most common professions. However, the role and added value of non-physicians is still unclear. The present study aimed to explore the possibilities for reallocating care to nonphysicians and identify drivers for and barriers to reallocation. Methods: A mixed-method design was used collecting quantitative and qualitative data from representatives of the main 4 Dutch professions providing acne care: dermatologists, GP’s, Dermal therapists and beauticians. Results: A total of 560 questionnaires were completed and 24 semi-structured interviews were conducted. A broad spectrum of non-physician tasks and responsibilities were delineated. Interviewed physicians considered acne as a low-complexity skin condition which made them willing to explore the possibilities for reallocating. A majority of all interviewees saw a key role for non-physicians in counselling and supporting patients during treatment, which they considered an important role for increasing patients’ adherence to proposed treatment regimes, contributing to successful clinical outcome. Also, the amount of time non-physicians spend on patients was experienced as driver for reallocation. Legislation and regulations, uncertainties about the extent of scientific evidence and proper protocols use within the non-physician clinical practice were experienced as barriers influencing the possibilities for reallocation. Conclusions: Delineated roles and drivers demonstrate there is room and potential for reallocation between physicians and non-physicians within acne healthcare, when barriers are adequately addressed.

Defining XR-specific teacher competencies: Extending the DigCompEdu framework for immersive education

Extended Reality (XR) technologies—including virtual reality (VR), augmented reality (AR), and mixed reality (MR)—offer transformative opportunities for education by enabling immersive and interactive learning experiences. In this study, we employed a mixed-methods approach that combined systematic desk research with an expert member check to evaluate existing pedagogical frameworks for XR integration. We analyzed several established models (e.g., TPACK, TIM, SAMR, CAMIL, and DigCompEdu) to assess their strengths and limitations in addressing the unique competencies required for XRsupported teaching. Our results indicate that, while these models offer valuable insights into technology integration, they often fall short in specifying XR-specific competencies. Consequently, we extended the DigCompEdu framework by identifying and refining concrete building blocks for teacher professionalization in XR. The conclusions drawn from this research underscore the necessity for targeted professional development that equips educators with the practical skills needed to effectively implement XR in diverse educational settings, thereby providing actionable strategies for fostering digital innovation in teaching and learning.

Introducing labour productivity changes into models used for economic impact analysis in tourism

In tourism management, traditional input-output models are often applied to calculate economic impacts, including employment impacts. These models imply that increases in output are translated into proportional increases in labour, indicating constant labour productivity. In non-linear input- output (NLIO) models, final demand changes lead to substitution. This causes changes in labour productivity, even though one unit of labour ceteris paribus still produces the same output. Final demand changes can, however, also lead to employees working longer, harder and/or more efficiently. The goal of this article is to include this type of 'real' labour productivity change into an NLIO model. To do this, the authors introduce factor augmenting technical change (FATC) and a differentiation between core and peripheral labour. An NLIO model with and without FATC is used to calculate the regional economic impacts of a 10% final demand increase in tourism in the province of Zeeland in the Netherlands. Accounting for real productivity changes leads to smaller increase in the use of labour, as productivity increases allow output to be produced using fewer inputs.

Reorganising dermatology care

Background: The substitution of healthcare is a way to control rising healthcare costs. The Primary Care Plus (PC+) intervention of the Dutch ‘Blue Care’ pioneer site aims to achieve this feat by facilitating consultations with medical specialists in the primary care setting. One of the specialties involved is dermatology. This study explores referral decisions following dermatology care in PC+ and the influence of predictive patient and consultation characteristics on this decision. Methods: This retrospective study used clinical data of patients who received dermatology care in PC+ between January 2015 and March 2017. The referral decision following PC+, (i.e., referral back to the general practitioner (GP) or referral to outpatient hospital care) was the primary outcome. Stepwise logistic regression modelling was used to describe variations in the referral decisions following PC+, with patient age and gender, number of PC+ consultations, patient diagnosis and treatment specialist as the predicting factors. Results: A total of 2952 patients visited PC+ for dermatology care. Of those patients with a registered referral, 80.2% (N = 2254) were referred back to the GP, and 19.8% (N = 558) were referred to outpatient hospital care. In the multivariable model, only the treating specialist and patient’s diagnosis independently influenced the referral decisions following PC+. Conclusion: The aim of PC+ is to reduce the number of referrals to outpatient hospital care. According to the results, the treating specialist and patient diagnosis influence referral decisions. Therefore, the results of this study can be used to discuss and improve specialist and patient profiles for PC+ to further optimise the effectiveness of the initiative.

Usefulness of non-linear input-output models for economic impact analyses in tourism and recreation

In tourism and recreation management it is still common practice to apply traditional input-output (IO) economic impact models, despite their well-known limitations. In this study the authors analyse the usefulness of applying a non-linear input-output (NLIO) model, in which price-induced input substitution is accounted for. For large changes in final demand, a NLIO model is more useful than a traditional IO model, leading to higher or lower impacts. For small changes in final demand input substitution is less likely. In that case the application of the NLIO may lead to the same results as a traditional IO model. To analyse changes of subsidies, a traditional IO model is not an option. A more flexible model, such as the NLIO, is required. The NLIO model forces researchers to make choices about capacity constraints, factor mobility and the substitution elasticity, which can be difficult but create flexibility and allow for more realism.
