Tourist mobility packages in an island mass tourism destination: Exploring preferences heterogeneity and willingness-to-pay

Ensuring a sustainable and efficient transportation system meeting visitor mobility needs is paramount for mass tourist destinations. Recognising this challenge, some destinations are embracing Mobility as a Service (MaaS) solutions as a strategy to create a more sustainable transportation system for tourists. This study uses a discrete choice experiment to analyse tourists’ preferences and willingness to pay for MaaS packages in two well-known municipalities of the Canary Islands, one of Europe’s premier mass tourism destinations. The empirical evidence of taste heterogeneity revealed by the analysis indicates that a one-size-fits-all solution is inadequate. Therefore, the development of mobility packages must be tailored to the specific needs of distinct tourist segments. This approach caters to individual preferences and maximises the perceived value for each tourist segment, promoting the adoption of sustainable transportation options.

Poly(lactic acid) and copper‐modified montmorillonite nanocomposite films for antimicrobial food packaging

AbstractPolymer‐based nanocomposites loaded with metal nanoparticles are an interesting alternative for the development of antimicrobial food packaging. However, affinity and dispersion of metal nanoparticles could be improved using nanoclays. Therefore, nanocomposite films based on poly(lactic acid) (PLA) and copper modified‐montmorillonite were developed by melt‐extrusion technique. Copper‐modified montmorillonite at different valence states (MtCu2+ and MtCu0) were prepared. The nanocomposites were evaluated by means of their structural, optical, thermal and antimicrobial properties. Results showed that both nanoclays were intercalated in PLA but MtCu2+ was better dispersed. Therefore, color change ΔE < 2, higher thermal stability and higher elongation at break was evidenced for MtCu2+/PLA in comparison to pure PLA. Contrary, MtCu0 showed the displacement of Cu0 nanoparticles to the polymer matrix. These free nanoparticles were agglomerated and they leaded on a ΔE > 9 for MtCu0/PLA nanocomposites compared with PLA. Moreover, Cu0 nanoparticles in the matrix accelerated the thermal degradation and decreased the ductility of nanocomposites. On the other hand, both nanocomposites were able to reduce over 2 log10 of Escherichia coli growth and MtCu2+/PLA showed a higher antimicrobial activity against Listeria innocua. These results showed the potential of nanocomposite films based on PLA and copper‐modified montmorillonite for antimicrobial food packaging applications.

Development of brief assessment packages of psychosocial constructs related to doping

Background We aimed to develop brief self-report tools that can be used by anti-doping organizations (ADOs) to evaluate education programs regarding their effects on psychosocial correlates of doping. Current assessment tools are too long for this purpose. Methods In phase 1, we reviewed the literature and selected psychosocial constructs perceived to be amenable to anti-doping education. In phase 2, a survey with these constructs was sent to anti-doping experts (i.e. researchers and representatives of ADOs), who rated their importance and rank ordered them. Following this, a smaller pool of constructs was chosen for phase 3, during which, questionnaires capturing these constructs were distributed to adult athletes and athlete support personnel (ASP) in Denmark, Norway, and Sweden. Results Using data from 307 adult athletes and 296 ASP, we selected the best 2–3 items for scales tapping each construct, via the OASIS package in R. Two questionnaires with 24 (athletes) and 28 (ASP) items, respectively, were formed. The questionnaires assess 11 and 13 different constructs, respectively, and capture diverse aspects such as morality, motivation, perceived benefits, and perceived deterrents relevant to doping. Conclusion The questionnaires provide brief assessments for diverse psychosocial constructs that could be used to evaluate ADO education programs.

Multi-functional reinforced food packaging using delivery carriers: A comprehensive review of preparation, properties, and applications.

With the rapid development of globalization, food packaging takes on more responsibility, while guaranteeing product quality and safety. In this context, the health risks associated with chemically synthesized additives and inorganic nanoparticles have opened a new chapter in the reinforcement of food packaging with natural active ingredients. Various delivery carriers have been developed to overcome the limitations of poor stability, uneven dispersion, and low bioavailability of natural active ingredients. The combination of encapsulation technologies can increase the biocompatibility of the active ingredient with the packaging material. Moreover, the protective and slow-release effects of the carrier matrix on the active ingredients are desirable for the reinforcement of food packaging. This review presents the latest advances in the application of delivery systems in food packaging, including the types of delivery systems used in food packaging, reinforced properties of food packaging, and potential applications in the food industry. Previous scientific studies found that active ingredient-loaded delivery carriers increased the effectiveness of food packaging in preventing food spoilage. Furthermore, the integration of active packaging with smart food packaging exhibits the synergistic effects of freshness monitoring and quality preservation. This review also discusses the challenges and trends in reinforcing food packaging with delivery carriers under a synergistic strategy that will provide new ideas and insights for the development and application of innovative food packaging.

Development of polycaprolactone-based electrospun nanofiber incorporated lemon beebrush essential oil-loaded metal-organic frameworks as a novel active food packaging for meat preservation

This research involved the development of novel antimicrobial and antioxidant food packaging using electrospun nanofibrous films (ENFs) made of polycaprolactone (PCL) with added lemon beebrush (Aloysia Citriodora) essential oil (LEO)–loaded chromium(III)-metal–organic framework (Cr(III)-MOF) to extend the shelf life of red meat. We conducted a comprehensive range of microstructure, physical, and mechanical tests on nanofibers based on PCL. The PCL/LEO@Cr(III)-MOF nanofibers displayed improved thermal stability, anti-deformation capacity, and increased TS (62.3–68.2 MPa) but reduced flexibility (32.6–28.2 %). Moreover, the inclusion of LEO@Cr(III)-MOF led to a decreased hydrophobic surface due to the formation of hydrogen bonds, as well as a reduction in the water vapor barrier (2.8–2.2 × 10−11 g m/m2. s. Pa). Additionally, the PCL/LEO@Cr(III)-MOF nanofibers exhibited antibacterial (E. coli (20.3 mm) and S. aureus (24.3 mm)) and antioxidant (DPPH and ABTS) activity. The effectiveness of PCL-based nanofibers was evaluated in red meat samples stored at a temperature of 4 °C, and the findings demonstrated that PCL/LEO@Cr(III)-MOF nanofibers preserved the chemical (pH, TVB-N, PV, and TBA) and microbial quality (PTC and TVC) of the samples and prolonged their shelf life by 18 days. These findings indicate the promising potential of the developed PCL/LEO@Cr(III)-MOF electrospun nanofibers for active food packaging.

Inhibition of Food Spoilage Fungi, Botrytis cinerea and Rhizopus sp., by Nanoparticles Loaded with Baccharis dracunculifolia Essential Oil and Nerolidol.

This study investigates the antifungal potential of encapsulated essential oil (EO) from Baccharis dracunculifolia and nerolidol (NE) within Pluronic® F-127 nanoparticles (NPs). The EO, containing nerolidol, β-caryophyllene, and α-pinene as major bioactive compounds, exhibited superior antifungal activity compared to NE. The NP-EO formulations demonstrated high efficacy against Botrytis cinerea, with inhibition rates ranging from 29.73% to 87.60% and moderate efficacy against Rhizopus sp., with inhibition rates from 11.81% to 32.73%. In comparison, NP-NE showed lower antifungal activity. Both formulations effectively inhibited spore germination, with NP-EO showing greater inhibition compared to NP-NE. The encapsulation efficiency was significantly higher for NP-EO (80.1%) as compared to NP-NE (51.1%), attributed to the complex composition of EO facilitating better encapsulation and retention. Stability studies indicated that both NP formulations were stable at 25 °C for at least 15 days and exhibited changes in particle size and the formation of smaller particle populations at other temperatures (4 °C and 37 °C). Hemolytic activity was low across all NPs, suggesting their safety for food applications. The findings underscore the efficacy and applicability of EO-encapsulated NPs in extending food shelf life and maintaining product quality. The controlled and prolonged release of active compounds, coupled with their antifungal activity and safety, suggests that these NPs represent a promising and innovative approach for food preservation and active packaging development.

Waterborne cellulose acetate pickering emulsion generation mediated by cellulose nanocrystals for paper coating applications

There is a continually increasing demand for alternatives to single-use, non-degradable, and synthetic plastic packaging. Environmentally friendly paper products offer a potential solution, but typically do not meet stringent demands for barrier and other physical property performance unless coated with polymeric films, usually polyolefins. Replacing conventional plastic film coatings with bio-based polymer alternatives, such as cellulose acetate, can provide competitive barrier property performance while also providing sustainability benefits. Furthermore, water can be used as a coating medium for added environmental and coatability advantages. In this study, 10 wt% Pickering emulsions of cellulose acetate dispersed in water and stabilized via cellulose nanocrystals (CNC) were generated. Rheological behavior, particle size, stability, and particle morphology were analyzed, as was the effect of modifying the CNCs using (2-Dodecen-1-yl)succinic anhydride over several weeks. Unbleached kraft paper was coated and compared to polyolefin coated and uncoated paper. Water vapor permeability, grease resistance, water absorption, and wet mechanical properties were all investigated, displaying promising properties for barrier paper coating. The grease kit test yielded a result of 10/12 for the coated paper versus 0/12 for uncoated, and water Cobb value showed a 60 % improvement. Lastly, the performance of the coated paper as a food takeout container coating was explored, with convincing results demonstrating a strong avenue of applicability. Overall, the waterborne cellulose acetate Pickering emulsion formation and its paper coating application yielded promising results for sustainable packaging development.

Precise modulation of the debonding behaviours of ultra-thin wafers by laser-induced hot stamping effect and thermoelastic stress wave for advanced packaging of chips

Abstract Laser debonding technology has been widely used in advanced chip packaging, such as fan-out integration, 2.5D/3D ICs and MEMS devices. Typically, laser debonding of bonded pairs (R/R separation) is typically achieved by completely removing the material from the ablation region within the release material layer at high energy densities. However, this R/R separation method often results in a significant amount of release material and carbonized debris remaining on the surface of the device wafer, severely reducing product yields and cleaning efficiency for ultra-thin device wafers. Here, we propose an interfacial separation strategy based on laser-induced hot stamping effect and thermoelastic stress wave, which enables stress-free separation of wafer bonding pairs at the interface of the release layer and the adhesive layer (R/A separation). By comprehensively analyzing the micro-morphology and material composition of the release material, we elucidate the laser debonding behavior of bonded pairs under different separation modes. Additionally, we have calculated the ablation threshold of the release material in the case of wafer bonding and established the processing window for different separation methods. This work offers a fresh perspective on the development and application of laser debonding technology. The proposed R/A interface separation method is versatile, controllable and highly reliable, and does not leave release materials and carbonized debris on device wafers, demonstrating strong industrial adaptability, which greatly facilitates the application and development of advanced packaging for ultra-thin chips.

Biotechnology in Food Packaging Using Bacterial Cellulose.

Food packaging, which is typically made of paper/cardboard, glass, metal, and plastic, is essential for protecting and preserving food. However, the impact of conventional food packaging and especially the predominant use of plastics, due to their versatility and low cost, bring serious environmental and health problems such as pollution by micro and nanoplastics. In response to these challenges, biotechnology emerges as a new way for improving packaging by providing biopolymers as sustainable alternatives. In this context, bacterial cellulose (BC), a biodegradable and biocompatible material produced by bacteria, stands out for its mechanical resistance, food preservation capacity, and rapid degradation and is a promising solution for replacing plastics. However, despite its advantages, large-scale application still encounters technical and economic challenges. These include high costs compared to when conventional materials are used, difficulties in standardizing membrane production through microbial methods, and challenges in optimizing cultivation and production processes, so further studies are necessary to ensure food safety and industrial viability. Thus, this review provides an overview of the impacts of conventional packaging. It discusses the development of biodegradable packaging, highlighting BC as a promising biopolymer. Additionally, it explores biotechnological techniques for the development of innovative packaging through structural modifications of BC, as well as ways to optimize its production process. The study also emphasizes the importance of these solutions in promoting a circular economy within the food industry and reducing its environmental impact.

Forecasting to support EMS tactical planning: what is important and what is not.

Forecasting emergency medical service (EMS) call volumes is critical for resource allocation and planning. The development of many commercial and free software packages has made a variety of forecasting methods accessible. Practitioners, however, are left with little guidance on selecting the most appropriate method for their needs. Using 5 years of data from 3 cities in Alberta, we compute exponential smoothing and benchmark forecasts for 8-hour periods for each ambulance station catchment area and with a forecast horizon of two weeks-a spatio-temporal resolution appropriate for tactical planning. The methods that we consider differ on three spectra: the number and type of time-series components, whether forecasts are computed individually or jointly, and the way in which forecasts at a specific resolution are converted to forecasts at the resolution of interest. We find that it is important to include a weekly seasonal component when forecasting EMS demand. Multiplicative seasonality, however, shows no benefit over additive seasonality. Adding other time-series components (e.g., trend, ARMA errors, Box-Cox transformation) does not improve performance. Spatial resolutions of station catchment area and lower, and temporal resolution of 4-24 hours perform similarly. We adapt an existing hierarchical forecasting framework to a two-dimensional spatio-temporal hierarchy, but find that hierarchical reconciliation of forecasts does not improve performance at the forecast resolution of interest for tactical planning. Neither does jointly forecasting time series. We show that added complexity does not materially improve forecasting performance. The simple methods that we find perform well are easy to implement and interpret, making implementation in practice more likely. In a simulation study we alter the empirical weekly patterns and demonstrate how extreme differences between the weekly seasonality patterns of different regions cause hierarchically-reconciled bottom-up approaches to outperform top-down approaches.

Production of Cellulose Nanofibers From Pineapple Peel (Ananas comosus) and Application in Biodegradable Films

AbstractThe waste of pineapple (Ananas comosus) juice accounts for 35% of the fruit's weight, and this organic material is rich in fibers and cellulose, making it a promising source for producing new ingredients for biodegradable packaging. This study objected to cellulose‐produced nanofibers from pineapple peel by chemical and enzymatic treatment combined with mechanical treatment and subsequently evaluated the application of these nanofibers as a reinforcing agent in biodegradable films. The cellulose nanofibers produced through enzymatic treatment with a sonicator presented the best results and were applied in biodegradable films at concentrations of 3% and 6%. The addition of 6% of cellulose nanofibers increased the tension (26.01 ± 0.78). It reduced the elongation percentage (3.27 ± 0.38) of films in addition to expanding the biodegradability, with up to 96% degradation observed after just 1 day. The use of nanofibers obtained from pineapple peel is a promising ingredient for the development of biodegradable packaging.

The Village Fund (VF) drives local economic growth by fostering ecotourism development. This study investigates the impact of the VF program on Local Economic Development (LED) in the Bah Biak Waterfall Ecotourism area, located in Sidamanik Sub-district, Simalungun Regency, North Sumatra. The VF program aims to enhance community income, create employment opportunities, and improve the productive capacity of rural communities. We use a purposive sampling method to collect data from 64 households out of 174 in the area. Critical indicators of LED, including local employment, household income, and expenditure, were analyzed using paired sample t-tests to compare conditions before and after using the VF. The results indicate a significant increase in local employment, household income, and expenditure following the utilization of the VF. This research underscores the importance of community participation in all stages of program activities, from planning to evaluation, and highlights the need for enhanced involvement in monitoring processes. The findings contribute to understanding how the VF can effectively support local economic development and provide recommendations for future ecotourism package development that integrates local resources and attractions. Future studies will focus on developing integrated ecotourism packages that combine multiple attractions and activities in the region, such as the panorama of tea plantations, Arabica coffee farming, creative economics based on beekeeping, and educational tourism related to sustainable practices.

Utilization of Local Wisdom of Antanan (Centella Asiatica) and Badotan (Ageratum Conyzoides L.) Plants for Anti-bacterial Edible Film of Pumpkin Seeds

Edible film is a thin layer made from consumable materials, formed on top of or placed between food components, functioning as a barrier to mass transfer such as moisture, oxygen, and solutes. It is made from edible biopolymers and food-grade additives. The development of edible film packaging in this study was carried out by utilizing pumpkin skin and seeds that have not been adequately used and by exploring the addition of natural antimicrobial compounds, namely antanan and badotan, to enhance the inhibitory effect of edible films made from pumpkin seeds that meet food standards.In this study, the extraction of yellow pumpkin seeds, antanan, and badotan was performed, followed by organoleptic and phytochemical tests. An edible film formulation was made from yellow pumpkin seeds, varied with antanan and badotan, and tested for moisture content, solubility, pH, and antibacterial properties. The characteristic test results showed that the badotan leaf simplicia was dark green, with a bitter taste and an astringent aromatic odor typical of badotan. The extract was blackish-green in color, with an aromatic odor typical of badotan, and a very bitter taste. Antanan leaf simplicia had a typical aromatic odor, an astringent taste, and was solid green in color. The antanan leaf extract had a typical antanan odor, a very bitter taste, and was thick green in color. Pumpkin seed simplicia had a typical pumpkin smell, an astringent taste, and was thick green in color. The pumpkin seed extract had a smell of ethanol solvent, a bitter taste, and was brownish-green and in the form of a thick liquid. The potential bioactive compounds in badotan leaves included alkaloids, steroids, phenolics, and saponins. Antanan leaves and pumpkin seeds contained flavonoids, alkaloids, steroids, phenolics, and saponins. The results showed that the edible film formulation of pumpkin seeds combined with badotan and antanan (1:2) appeared tighter and smoother and did not break. The formulation of pumpkin seeds and badotan (1:2) had a moisture content of 0.0380%, a solubility content of 0.2075%, and a pH of 5.8. The pumpkin seed and antanan (1:2) formulation had a moisture content of 0.0732%, a solubility content of 5.7269%, and a pH of 5.8. The edible film antibacterial activity test against Staphylococcus aureus used the disc diffusion method and obtained an inhibition zone of 1.8 mm for pumpkin seed edible film, 12.4 mm for pumpkin seed (1:2) edible film, and 17.6 mm for pumpkin seed (1:2) edible film.

Synthesis of evidence for managing hypertensive disorders of pregnancy in low middle-income countries: a scoping review

Background and objectivesHypertensive disorders of pregnancy (HDPs) remain one of the leading causes of maternal mortality globally, especially in Low- and middle-income countries (LMICs). To reduce the burden of associated morbidity and mortality, standardized prompt recognition, evaluation, and treatment have been proposed. Health disparities, barriers to access to healthcare, and shortage of resources influence these conditions. We aimed to synthesize the literature evidence for the management of HDPs in LMICs.MethodsA scoping review was conducted in five databases (PubMed, Web of Science, Epistemonikos, Clinical Key and, Scielo) using MeSh terms, keywords, and Boolean connectors. We summarized the included studies according to the following categories: study design, objectives, settings, participant characteristics, eligibility criteria, interventions, assessed outcomes, and general findings.ResultsSix hundred fifty-one articles were retrieved from the literature search in five databases. Following the selection process, 65 articles met the predefined eligibility criteria. After performing a full-text analysis, 27 articles were included. Three themes were identified from the articles reviewed: prevention of HDPs, management of HDPs (antihypertensive and non-hypertensive management) and pregnancy monitoring and follow-up. The topics were approached from the perspective of LMICs.ConclusionsLMICs face substantial limitations and obstacles in the comprehensive management of HDPs. While management recommendations in most LMICs align with international guidelines, several factors, including limited access to crucial medications, unavailability of diagnostic tests, deficiencies in high-quality healthcare infrastructure, restrictions on continuing professional development, a shortage of trained personnel, community perceptions of preeclampsia, and outdated local clinical practice guidelines, impede the comprehensive management of patients. The development and implementation of protocols, standardized guides and intervention packages are a priority.

Biodegradable packaging with natural colorants added to increase the consumption of eco-friendly packaging

The development of biodegradable packaging is relevant for the environment, society, and industry. In parallel, using natural colorants has also emerged as a current topic in research, for its appeal to both human and environmental health. Combining the concepts of biodegradable packaging and natural colorants in a single product presents as a strategy to increase the potential use of biodegradable packaging. In this sense, this project starts with the following hypothesis: the offer of biodegradable packaging with a natural colorant added improves the positive perception of biodegradable packaging by the consumer. To this end, using the Food Choice Questionnaire (FCQ), the present work seeks to understand the effect of the construct natural content on the importance given by consumers to foods that are packaged in an environmentally friendly way, and using Word Association (WA) technique, to investigate the influence of color, and awareness of the presence of natural colorants on biodegradable packaging. The study was designed using two approaches: (i) Developing a model using Partial Least Squares-Path modeling (PLS-PM) to explain the whole set of relationships between FCQ constructs of interest in eco-friendly packaging, being mediated by the construct natural content; and (ii) using WA technique under two conditions: blind condition (unaware) and informed condition (aware) to explore the holistic perception of colored biodegradable packaging. Results showed that Ethical concerns and Health, had positive effects on Natural Content, while “weight control” had a positive effect on Natural Content. On the other hand, Mood was found to have a negative effect on Natural Content. Natural content has a high effect on the importance given by consumers to foods packaged in an environmentally friendly way. Word Association revealed a positive perception of the presentation of colored biodegradable packaging and a more positive perception, defined by happiness, of the awareness of its being biodegradable packaging colored by natural colorants. From a practical point of view, results showed that not only the use of natural colorants by the packaging industry can serve as an incentive to consume biodegradable packaging, but that consumers' awareness that the color is from a natural colorant can increase the consumption of eco-friendly packaging.

Sustained-release composite films incorporated with cinnamon essential oil: Characterization, release kinetics and application for cherry tomato preservation

Food spoilage waste accelerated the development of bio-based active food packaging. Sustained-release composite films based on oxidized corn starch/ pullulan were prepared by incorporating cinnamon essential oil (CEO) nanoemulsion. The SEM, ATR-FTIR and XRD results showed that CEO was successfully encapsulated in film matrixes. The composite films exhibited the increase of thermal stability, UV-shielding, flexibility and water vapor resistance properties. The films containing CEO nanoemulsion (≥10%) showed excellent antimicrobial activities against S. aureus, E. coli and B. cinerea (the maximum inhibition zones achieving 27.23 ± 2.31 mm). The release kinetics results showed sustained release of CEO from the films with high content of CEO nanoemulsion, and the dominant release mechanism was Fickian diffusion. The composite films effectively maintained cell structure, weight, firmness and total soluble solids content of fruits during storage. Therefore, the sustained-release composite films could be a prospective packaging material for fruits preservation.
