Globally, the most prominent opportunities for sustainability change in housing production lie in multistory residential buildings, which are built mainly of concrete, steel, and bricks. The possibilities of achieving multiple benefits from the use of wood in multistory residential buildings have gained interest among scholars, especially in the 2000s. However, the research has been dominated by views of production (especially construction processes), while scientific knowledge of consumption (especially the occupational phase of buildings) remains very limited. Information about how consumers with differing views of sustainable consumption evaluate the quality of wooden building materials particularly is scarce. This study aimed to investigate consumer perceptions of wooden building product quality and examine how the perceptions connect with consumers' consciousness for sustainable consumption (CSC). The research data were gathered in 2018 by a postal survey sent to 1,000 people living in Finland (response rate 25.6%) and analyzed with exploratory factor analysis and the Mann-Whitney U test. According to the results, respondents' views of wooden building product quality indicators can be grouped into three factors: technical advantages, environmental sustainability of materials, and social benefits at home. The strength of CSC was found to be linked with respondents' views of wooden building product quality. The results of consumers' CSC views help actors involved in the wood and construction industries better meet consumer expectations both for different aspects of sustainability and for lifestyles.","PeriodicalId":12387,"journal":{"name":"Forest Products Journal","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45692827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the related undergraduate degree programs are neither gender nor ethnically representative of current U.S. demographics. A program model framework called Inside Trees was developed and tested in this project for an in-person summer camp and remote learning modules to help raise awareness and form a pipeline between high school students and future enrollment in higher-educational degree programs. To gain a better understanding of logistics, a prototype summer camp was delivered to 12 students, 10 of whom were women, 3 were first-generation college students, 1 was African American, and 1 was Hispanic/Latino. Three students who attended the Inside Trees summer camp enrolled at Virginia Tech University the following year. Content and activities from the summer camp were later converted into digital learning modules that could be used with a summer camp or as separate teaching/learning units. Review of supporting literature and informal student feedback indicates that a summer camp program that includes experiential learning, a positive experience in nature, support through the higher-educational academic program, multiple disciplines, and career opportunities shows good potential to be an effective pipeline to increase diversity in the bio-based industry. It is suggested that the Inside Trees model curriculum and framework could be adapted by other universities or organizations for achievement of institution-specific goals toward improved awareness and enrollment of underrepresented students.","PeriodicalId":12387,"journal":{"name":"Forest Products Journal","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46918137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The laboratory test was designed to mimic the fire tests described in Annex B of the ANSI/APA PRG-320 standard, which is required for CLT product qualification in North America. The Annex B test requires a full-sized room (2.4 by 4.9 by 2.7 m) to be constructed and exposed to a design fire scenario. In this article, we scaled the mechanical and fire loads so that they could be conducted in an intermediate-scale furnace with 1.1 m2 of exposed CLT panels. The mechanical loads were scaled to match the bending moment prescribed in the standard. The fire loads were scaled by matching the temperature profiles when an inert furnace lid was run and then matching the gas flow on all subsequent tests. Panels made from adhesives that passed the Annex B test passed the laboratory-scale test; panels that failed the Annex B test failed the laboratory test with the exception of one replicate. Correlations were found not only for CLT but also for a veneer-based mass timber panel. Measured temperature profiles within the furnace were similar to those measured near the compartment ceiling in the Annex B test. The scaled-down test in this article can be used to screen which adhesives are likely to pass the full-scale Annex B test.","PeriodicalId":12387,"journal":{"name":"Forest Products Journal","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42121590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species tested include ash (Fraxinus sp.), hickory (Carya sp.), red oak (Quercus sp.), sweetgum (Liquidambar styraciflua), and white oak (Quercus sp.). The abrasion test was performed according to the American Society of Testing and Materials standards. Ten specimens from each species were initially tested for abrasion resistance, and those specimens were then put through a thermomechanical densification process. The densification process consisted of bringing the heated platen up to a temperature of 176°C (350°F) on one surface and pressing the specimens at 6.9 MPa (1,000 Psi) for a period of 5 minutes. The densified specimens were then subject to the same abrasion testing procedure. All data were statistically analyzed by two-way analysis of variance (ANOVA) with the procedure of general linear mixed models. The results of this study indicated that densified hickory had the highest abrasion resistance among the five hardwood species tested.","PeriodicalId":12387,"journal":{"name":"Forest Products Journal","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43704242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, different species and individuals from the same species can show variations in the chemical composition, resulting in the risk of nonuniform color development in industrial staining processes between different batches of wood. In the present study, near-infrared (NIR) models were developed to predict wood specimen color development after applying three different concentrations of the chemical stains iron acetate and sodium bicarbonate. The modeling dataset included the NIR spectra of the untreated wood, stain treatment, concentration, and the International Commission on Illumination (CIE) L*a*b* color value before stain application for 210 specimens from five commercial wood species, including red oak (Quercus rubra), white oak (Quercus alba), yellow poplar (Liriodendron tulipifera), southern yellow pine (Pinus spp.), and western red cedar (Thuja plicata). The models were developed by partial least squares regression (PLSR), using 13 different mathematical transformations on the NIR spectra as well as the raw spectral data. Models with single stains and global-species/stain models were developed and compared. The models for iron acetate showed promising results in predicting the color development with the coefficient of determination for cross-validation ( ≥ 0.92), while the models for sodium bicarbonate showed acceptable results with of 0.71 to 0.89. However, a global model including both stains resulted in an unsatisfying prediction of the CIE L*a*b* color values, with of 0.46 to 0.76. The NIR models can be useful for online predictions of color development in industrial staining processes of wood with chemical stains.","PeriodicalId":12387,"journal":{"name":"Forest Products Journal","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48736453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
