Abstract Wood in Austria has been an indispensable source of energy, but also, a crucial building material. In the field of dendroarchaeology the timeline between raw material harvest and finalisation of a wooden construction is a crucial piece of puzzle in understanding building history. This paper aims to provide an overview on historical timber supply in Austria by examining the felling and debarking methods, as recorded in old literature and, from the visible evidence on beams in wooden constructions. Historically, depending on the size and location of a building, a small or extended supply chain of timber was required. These generally consisted of logs travelling via streams and rivers, and possibly beforehand passing through sluices and log slides, being skidded by horses and oxen, and being moved by manpower on sleighs, or simply on the forest floor. The seasonal working steps of the logging process included felling, debranching, debarking, cutting to length, and the start of the transportation process. Debarking was a specific focus in this investigation, as the appearance of bast (the inner bark of trees from which ropes were made) or even bark residues on the waney edge (outermost growth ring underneath the bark), may provide a clue to the felling time of year. These indications of the cutting season have been noticed during dendrochronological sampling of beams in historical buildings. Improved knowledge of them may contribute to future research of these buildings.

Ostrich eggshell (OES) beads are a common feature of Later Stone Age (LSA) archaeology throughout eastern and southern Africa and have the potential to inform on site use, cultural diversity, social networks, and site formation. However, too often OES bead assemblages have not been recorded or studied in the necessary detail to make meaningful contributions to these important questions. In this respect, and to aid future research focusing on the African LSA, OES and OES beads must be discussed in detail, beginning with a background to ostriches and their eggs and commenting on why OES is an important raw material. Then, one should consider OES beads in detail, specifically, the manufacturing process, the social context in which they were made, and how they may have been used in the past. Subsequently, the focus should be on how OES bead assemblages are analyzed, as well as archaeometric approaches to studying OES bead residues and OES bead provenance. The potential insights gained from these diverse and multidisciplinary analytical approaches, especially when combined, are then highlighted through discussing trends in OES bead research from African LSA contexts. These trends include the contribution of OES beads to understanding the complex transition from hunter-gatherers to herders, the identification of different cultural groups in the past, and identifying the presence and extent of past social networks. The final focus should be on future research directions that will benefit OES bead research, specifically more detailed approaches to understanding OES bead diversity and the expansion of experimentally derived taphonomic frameworks for identifying past human and nonhuman behaviors in OES bead assemblages. Future research should build on the growing body of detailed OES bead analyses, as they provide unique insight and a strong complement to traditional archaeological approaches to understanding past peoples, groups, and cultures during the African LSA.

Nanocelluloses (NCs) are bio-based nano-structurated products that open up new solutions for natural material sciences. Although a high number of papers have described their production, properties, and potential applications in multiple industrial sectors, no review to date has focused on their possible use in cementitious composites, which is the aim of this review. It describes how they could be applied in the manufacturing process as a raw material or an additive. NCs improve mechanical properties (internal bonding strength, modulus of elasticity (MOE), and modulus of rupture (MOR)), alter the rheology of the cement paste, and affect the physical properties of cements/cementitious composites. Additionally, the interactions between NCs and the other components of the fiber cement matrix are analyzed. The final result depends on many factors, such as the NC type, the dosage addition mode, the dispersion, the matrix type, and the curing process. However, all of these factors have not been studied in full so far. This review has also identified a number of unexplored areas of great potential for future research in relation to NC applications for fiber-reinforced cement composites, which will include their use as a surface treatment agent, an anionic flocculant, or an additive for wastewater treatment. Although NCs remain expensive, the market perspective is very promising.

Isatis tinctoria L. (Brassicaceae), which is commonly known as woad, is a species with an ancient and well-documented history as an indigo dye and medicinal plant. Currently, I. tinctoria is utilized more often as medicinal remedy and also as a cosmetic ingredient. In 2011, I. tinctoria root was accepted in the official European phytotherapy by introducing its monograph in the European Pharmacopoeia. The biological properties of raw material have been known from Traditional Chinese Medicine (TCM). Over recent decades, I. tinctoria has been investigated both from a phytochemical and a biological point of view. The modern in vitro and in vivo scientific studies proved anti-inflammatory, anti-tumour, antimicrobial, antiviral, analgesic, and antioxidant activities. The phytochemical composition of I. tinctoria has been thoroughly investigated and the plant was proven to contain many valuable biologically active compounds, including several alkaloids, among which tryptanthrin, indirubin, indolinone, phenolic compounds, and polysaccharides as well as glucosinolates, carotenoids, volatile constituents, and fatty acids. This article provides a general botanical and ethnobotanical overview that summarizes the up-to-date knowledge on the phytochemistry and biological properties of this valuable plant in order to support its therapeutic potential. Moreover, the biotechnological studies on I. tinctoria, which mainly focused on hairy root cultures for the enhanced production of flavonoids and alkaloids as well as on the establishment of shoot cultures and micropropagation protocols, were reviewed. They provide input for future research prospects.

We used a simulation model to investigate possible effects of a severe mountain pine beetle (Dendroctonus ponderosaeHopkins) epidemic under two management scenarios in Alberta, Canada. Our simulated outbreak was based on the current epidemic in British Columbia, which may kill close to 80% of the province's pine volume. Our two management scenarios were conventional harvest and a pine-reduction strategy modeled on a component of Alberta's Mountain Pine Beetle Management Strategy. The pine strategy seeks to reduce the number of susceptible pine stands by 75% over the next 20 years through targeted harvesting by the forest industry. Our simulations showed that the pine strategy could not be effectively implemented, even if the onset of the beetle outbreak was delayed for 20 years. Even though we increased mill capacity by 20% and directed all harvesting to high volume pine stands during the pine strategy's surge cut, the amount of highly susceptible pine was reduced by only 43%. Additional pine volume remained within mixed stands that were not targeted by the pine strategy. When the outbreak occurred in each scenario, sufficient pine remained on the landscape for the beetle to cause the timber supply to collapse. Alternative management approaches and avenues for future research are discussed.

Abstract Lonicera caerulea L., also known as honeysuckle berries, are rich in biologically active compounds, which makes them a valuable raw material for the development of functional foods. The objects of the research were three honeysuckle cultivars (‘Zoluška’, ‘Siņaja Ptica’, ‘Goluboje Vereteno’), four genotypes (No 2A; No 3; No 5; No 8) and kefir, enriched with various amounts (3–10%) of fruit puree. Physical and chemical analyses to determine the qualitative indicators of raw materials and products were performed. The degree of liking of kefir was assessed using sensory analysis: hedonic and line scales. The results obtained showed that among the cultivars the highest content of anthocyanins (1103.5 mg·100 g−1), total phenols (693.3 mg·100 g−1), flavonoids (753.9 mg·100 g−1), and tannins (1.6 mg·100 g−1), were found in ‘Siņaja Ptica’ berries, while among the genotypes, berries of No 8 had the highest concentration of the aforesaid compounds. Both samples also showed the highest antiradical activity: ABTS+• on average by 71.7% and DPPH− by 43.7%. According to the sensory evaluation, kefir with 10% honeysuckle puree was rated the highest. Honeysuckle berries could be used as a promising source of natural anti-oxidants in future research aimed at developing different new products that could meet consumer expectations.

Abstract The sustainability integration to achieve circular economy pressures the development of renewable raw material and bioenergy sources, including marine biomass such as macroalgae. The consideration of sustainable conversion technology for bioenergy from macroalgae is critically highlighted. Various studies have been emphasized that life cycle assessment (LCA) can be applied to assess the efficacy and environmental aspects of bioenergy production from cradle-to-grave. This systematic review attempts to critically evaluate the development of LCA studies on macroalgae valorisation for bioenergy. Several online databases (i.e., Science Direct, Wiley Online Library, Springer, DOAJ, and MDPI) were used to collect the relevant articles. Then, PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) method has been selected to screen the most recent research articles (from January 2011 to June 2021) published in peer-reviewed international journals. The studies presented the development, opportunities, challenges, and future research for the commercialization of macroalgae as a sustainable feedstock for bioenergy.

Objective – Literature suggest that companies should focus their Market Orientation (MO) on good marketing and business performance. However, previous research in this area deals mostly with large companies. The objective of this research is to study the significance of MO for small and medium enterprises (SMEs) with the specific production strategy of Make-To-Order. Methodology/Technique – The sample of this study is 111 Indonesia SMEs. The descriptive research design is supported by exploratory research. The structural model is analysed using the Structural Equation Modelling approach with LISREL 8.8 and SPSS 16.00. Findings – The result shows that MO does not have a significant impact on Marketing Performance. In the context of MTO, SMEs do not need to have a high Market Orientation to have satisfactory performance. It is more important for them to take care of the relationship with their principal companies. Government regulations, such as raw material regulations, also have an impact on SMEs performance. It is recommended that future research explore the types of capabilities of SMEs relating with the era of Industry 4.0. Other strategic orientations, such as production orientation, could be considered as factors in future research. Type of Paper: Empirical Keywords: Strategic Leadership Competence; Entrepreneurial Orientation; Market Orientation; Dynamic Marketing Capability; Business Environment; Marketing Performance; Maklun (MTO Strategy).

Purposes – This paper presents the idea that food quality management and control should be based on marketing orientation perspectives. It aims to explore the cues, reasons, criteria and sources of perceived quality and food risks, then investigates their influences on consumer satisfaction and consumption toward food (fish) in Vietnam. Finally, it recommends some directions for future research in both food marketing and Quality Control. Methods – This presentation is based on a range of research studies using different data sets collected across provinces in Vietnam, and using different methods to analyze the data and test constructs, hypotheses and models. Findings – First, it indicates that nutrition and taste occupy the highest ratio explaining for positive attitudes (positive perceived quality), while safety and negative feelings are dominated to explain negative attitudes (food risks). Consumers with more positive (negative) reasons have a higher (lower) consumption. Second, perceived quality as a a multidimensional construct is found to have a positive effect on consumer satisfaction, while negative feelings have a negative effect on satisfaction. Perceived price has no a significant influence on satisfaction but a significant positive effect on perceived quality. The results also show that there are four groups of reasons causing food risks coming from producers, sellers, consumers and products. Perceived food risk is found to have an indirect effect on consumption via consumer satisfaction, and negatively moderate the satisfactionconsumption relationship. However, the effect of perceived risks is weaker when consumer knowledge increases. Finally, ambivalence is found to have a negative direct effect on both satisfaction and health involvement. Both ambivalence and health involvement are found to moderate the satisfaction–consumption relationship in a complex mechanism. Managerial implications – Managers and marketers should pay attention to reasons for consumer attitudes and consumption and have a multidimensional view of food quality and risk. Marketing strategies, which reduce consumer risks and educate them with relevant knowledge, may be effective strategies to increase consumption. For Quality Control, it is important that they must understand not only the established sensory standards for product quality, but also know, if possible, consumer expectations of sensory evaluations particularly at target markets pursed by a food company. Quality Control must understand all the traceable systems from raw material sourcing to finished products, and find and prevent all kind of tricks and methods that producers, processors and sellers use to avoid or even go around the specifications for the lack of the right raw material at the right time. It is important to recruit Quality Control Inspectors who can do all this right and have the basic knowledge. Limitation and future research – This paper focuses on only fish. Future research should expand to other foods and try to answer the following research questions: Do the certainty or stability of perceived quality affect and/or interact with consumer satisfaction to increase consumption/loyalty? Do perceived food quality and perceived price interact to influence consumer satisfaction and consumption? Do perceived food quality and perceived risk interact to influence consumer satisfaction and consumption? What form of risk interacts with what dimension of perceived quality to influence consumer satisfaction and consumption? How can each kind of consumer knowledge help to decrease the negative effects of food risks? How can Quality Control and quality programs be built to solve the problems of fishing vessels, farmers, processors, marketing sectors and the consumers, and to increase the consumer’s security in health and nutritional values.
