The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is an instrument to screen substance-use-related health risks. However, little is known whether the ASSIST could be further shortened while remaining psychometrically sound across different countries, languages, gender identities, and sexual-orientation-based groups. The study aimed to validate a shortened 11-item ASSIST (ASSIST-11). Using the International Sex Survey data, 82,243 participants (M _age = 32.39 years) across 42 countries and 26 languages completed questions from the ASSIST-11 regarding gender identity, sexual orientation, and other information. Confirmatory factor analysis (CFA) and multigroup CFA (MGCFA) evaluated the ASSIST-11's structure and tested measurement invariance across groups. Cronbach's α and McDonald's ω were used to examine the internal consistency. Cohen's d and independent t-tests were used to examine known-group validity. The ASSIST-11 was unidimensional across countries, languages, age groups, gender identities (i.e., men, women, and gender-diverse individuals), and sexual orientations (i.e., heterosexual and sexual minority individuals). Cronbach's α was 0.63 and McDonald's ω was 0.68 for the ASSIST-11. Known-group validity was supported by Cohen's d (range between 0.23 and 0.40) with significant differences (p-values<0.001). The ASSIST-11 is a modified instrument with a unidimensional factor structure across different languages, age groups, countries, gender identities, and sexual orientations. The low internal consistency of the ASSIST-11 might be acceptable as it assesses a broad concept (i.e., use of several different substances). Healthcare providers and researchers may use the ASSIST-11 to quickly assess substance-use information from general populations and evaluate the need to follow up with more detailed questions about substance use. © 2023 Elsevier Ltd

One of the most popular food produced by extrusion process are the snacks. The quality of this product is related to sensory factors such as appearance and taste, with emphasis on texture. However, it is very difficult to find studies with correlations between descriptive and instrumental analyses for texture. The objective of this study was to perform extruded snacks instrumental and sensory analysis, crossing the obtained data and enabling correlations between them. Corn snacks were extruded on equal parameters in a complete IMBRA RX50 extrusion line (INBRAMAQ, Ribeirão Preto SP, Brazil), and then, the snacks were divided into four treatments modifying the moisture contents. These four treatments were also flavoured and stored for later physical analysis of moisture, water solubility, water absorption, water activity, colour, expansion ratio, specific volume, apparent density, retraction index and texture, the last one both instrumental and sensorial. Sensorial evaluation was performed by hedonic scale with 112 panellists, evaluating snacks texture, flavour and overall appearance. The snacks were analysed in Texture Analyzer TAXT2 Plus, using five different probes and varying the test speeds. Through the obtained results, it was possible to accomplish an excellent correlation between the data since the R values found varied between-0.91 and -0.99. Conclusively, the instrumental tests can replace sensory evaluation for texture attribute in extruded snacks. © Copyright 2017, AIDIC Servizi S.r.l.

Objectives: The 12-item Self-Compassion Scale–Short Form (SCS–SF) is a widely used instrument for the assessment of self-compassion. To date, there have been few examinations of this instrument’s psychometric properties, particularly across nations and languages. Therefore, we used data from the Body Image in Nature Survey (BINS) to assess measurement invariance of the SCS–SF across nations, languages, gender identities, and age groups. Methods: Participants (N = 56,968) from 65 nations completed the SCS–SF in 40 languages. Using these data, we tested various hypothesised models of the SCS–SF in the total sample and, using multi-group confirmatory factor analysis, tested for invariance of the optimal model across national groups, languages, gender identities, and age groups. Results: In the total dataset, we found that an 11-item, 2-factor model (i.e., SCS-11) provided best fit to the data, with the two factors tapping distinct constructs of compassionate and uncompassionate self-responding. The SCS-11 was found to be partially scalar invariant across national groups and languages, and fully scalar invariant across gender identities and age groups. There was wide variation in latent means for the two factors, particularly across national groups and languages. Further analyses showed negligible associations between the two factors and sociodemographic variables, including marital status, financial security, and urbanicity. Conclusions: Our results suggest that it may be possible to derive a stable 2-factor model of the SCS–SF for use in cross-cultural research, but also highlight the likelihood of cross-national and cross-linguistic variations in the way that self-compassion is understood. © The Author(s) 2025.

Drying was one of the primary processes in essential oil production. Time factor in drying affects both the content and chemical compositions of essential oils. This study aims to evaluate the influence of the drying time of kaffir lime leaves on the yield at room temperature and the major volatile compounds in the essential oils by observing day-to-day treatments. As a key odorants in essential oils, the quantity of citronellal was determined by Gas Chromatography (GC) using the standard compound. Based on the daily observation results, a long-time drying gave a significant effect on the yield and the major volatile compounds. The highest yield 1.26±0.07 % (w/w) was obtained on the fourth day, while the highest content of citronellal compounds, 87.58±0.33% was achieved on the fifth day of drying,. A prolonged drying time resulted in a negative effect on not only the quantity, but also the quality of essential oils. Accordingly, this study suggests that the drying technique at room temperature best lasts for four until five days to obtain the most favorable quality and quantity of essential oils.

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions’ effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior—several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people’s initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors. © 2024 American Association for the Advancement of science.

IOP Conference Series: Earth and Environmental science 2019年第1期292卷

作者： N Yaqin A N Al-Baarri A M Legowo Widayat M A Budihardjo Program of Environmental Science School of Post Graduate Studies Diponegoro University Semarang Indonesia Center of Research and Services-Diponegoro University Semarang Indonesia Food Technology Department Faculty of Animal and Agricultural Sciences Diponegoro University Semarang Indonesia Chemical Engineering Department Faculty of Engineering Diponegoro University Semarang Indonesia Department of Environmental Engineering Faculty of Engineering Diponegoro University Indonesia

Cassava is an agricultural material that is considered as important raw resources in the industrial sector. The benefits are even greater after being modified using lactic acid bacteria. However, the mocaf industry often causes water and air pollution. Environmental problems arise after the fermentation process. Determination problems with lightness, TDS (Total Dissolved Solid), conductivity and pH analysis are required to measure the impact to the environment. This research was used waste water from mocaf during 3 days fermentation. The wastewater had the highest color level (Lightness) on initial day of fermentation at 83.7±3.73 and then decrease along the day of fermentation at the averages of 65.2±2.0. The highest TDS was resulted from the mocaf wastewater at a value of 1218 ± 4.6 ppm which continued to decline until day 4. The conductivity and pH showed a decrease along the day of fermentation. As conclusion, physical characteristic of wastewater from mocaf production could be analyzed specifically and determined through color, TDS, conductivity, and pH.

Mechanical properties of chemically modified Sansevieria trifasciata/natural rubber/high density polyethylene (STF/NR/HDPE) composites: Effect of silane coupling agent

引用

AIP Conference Proceedings 2018年第1期1940卷

作者： Nurzam Ezdiani Zakaria Azizah Baharum Ishak Ahmad 2School of Chemical Sciences and Food Technology Faculty of Science and Technology National University of Malaysia 43600 UKM Bangi Selangor Malaysia 3Food Processing and Packaging Program Food Science Technology Research Centre Malaysian Agricultural of Research and Development Institute P.O Box 12301 General Post Office 50774 Kuala Lumpur Malaysia 1Polymer Research Center Faculty of Science and Technology National University of Malaysia 43600 UKM Bangi Selangor Malaysia

The main objective of this research is to study the effects of chemical modification on the mechanical properties of treated Sansevieria trifasciata fiber/natural rubber/high density polyethylene (TSTF/NR/HDPE) composites. Processing of STF/NR/HDPE composites was done by using an internal mixer. The processing parameters used were 135°C for temperature and a mixing rotor speed of 55 rpm for 15 minutes. Filler loading was varied from 10% to 40% of STF and the fiber size used was 125 µm. The composite blends obtained then were pressed with a hot press machine to get test samples of 1 mm and 3 mm of thickness. Samples were evaluated via tensile tests, Izod impact test and scanning electron microscopy (SEM). Results showed that tensile strength and strain value decreased while tensile modulus increased when filler loading increased. Impact strength increased when filler loading increased and began to decrease after 10% of filler amount for treated composites. For untreated composites, impact strength began to decrease after 20% of filler loading. Chemical modification by using silane coupling agent has improved certain mechanical properties of the composites such as tensile strength, strain value and tensile modulus. Adding more amount of filler will also increase the viscosity and the stiffness of the materials.
