The aim of this study is to review the innovative techniques based on bioprocessing, thermal or physical treatments which have been proposed during the last few decades to convert rice bran into a valuable food ingredient. Rice bran (Oryza sativa) is the main by-product of rice grain processing. It is produced in large quantities worldwide and it contains a high amount of valuable nutrients and bioactive compounds with significant health-related properties. Despite that, its application in food industry is still scarce because of its sensitivity to oxidation processes, instability and poor technological suitability. Furthermore, the health-related effects of pretreated rice bran are also presented in this review, considering the up-to-date literature focused on both in vivo and in vitro studies. Moreover, in relation to this aspect, a brief description of rice bran arabinoxylans is provided. Finally, the application of rice bran in the food industry and the main technology aspects are concisely summarized.

Waste management systems are overloaded with huge streams of plastic, a large part of this being originated from packaging. Additionally, the production of wheat, one of the most cultivated crops in the world, generates low-value lignocellulosic materials, which are mostly discarded. In this study, the wheat lignocellulosic byproducts straw and bran were used for the co-production of enzymes and bio-based materials with possible application as packaging via the compression molding method. The mechanical properties of the films were studied based on the effects of the removal of lignin by alkali and biological pretreatment, the growth of filamentous fungi, the size of the particles, and the enzyme recovery. Generally, the straw films were stiffer than the bran ones, but the highest Young’s modulus was obtained for the biologically pretreated bran (1074 MPa). The addition of a step to recover the fungal cellulases produced during the cultivation had no statistical effect on the mechanical properties of the films. Moreover, alkali and biological pretreatments improved the anaerobic biodegradability of the straw films. Thus, the wheat bran and straw can be used for the co-production of enzymes, materials, and biogas, potentially changing how wheat and packaging wastes are managed.

The present article describes the adsorption behavior of some low cost adsorbents such as olive waste, maize cobs, bentonitic clay, wheat bran, coal ash and coffee waste, with respect to Pb2+, Cu2+ and Zn2+ ions. The batch method was used and parameters such as electrical conductivity, pH, contact time, adsorbent dosage and initial and final concentration of metal ions were studied. All used adsorbents were effective, but coal ash was most effective, with total removal for all ions of over 90%, with highest percentage removal from 99.2% for Zn2+ ions and 97.5% of Pb2+. Maize cob was an effective adsorbent with maximal percentage removal of 92.6% for Zn2+ ions, wheat bran had highest removal of 93.7% for Pb2+ ions as did olive waste, 97% for Pb2+ ions. Coffe waste offers considerable promise as a low-cost natural adsorbent with highest efficiency in removal of Pb2+ with 97.5% while bentonitic clay having a structure with net negative charge, which is neutralized by positively charged species, resulted also as an effective low cost adsorbent with max total removal from 92.7% for Pb2+ to 80.9% for Zn2+ ions.

Ferulic acid, a compound showing antioxidant ability, is found in abundance in wheat bran. Its release depends mainly on the breaking of its ester linkage to other constitutive elements of the cell wall, such as arabinoxylans, ligin, cellulose and so on. Response surface methodology and orthogonal design were respectively used to evaluate the effects of NaOH concentration, alkali/ethanol ratio, extraction temperature and pH on ferulic acid extraction yield from wheat bran. The released ferulic acid concentration was determinated by HPLC method Experiments carried out under the predicted optimal conditions，with NaOH concentration of 5.76%, pH of 3.2, alkali/ethanol ratio of 1.39:1, temperature of 59.75 °C, the actual extraction yield in agreement with the expected yield, with 4.45mg.g-1 extraction rate of ferulic acid in wheat bran . And the results confirm the potential of wheat bran valorization in the field of natural antioxidant extraction, possibly viable in an industrial scheme.

In this work, processability and mechanical performances of bio-composites based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) containing 5, 10, and 15 wt % of bran fibers, untreated and treated with natural carnauba and bee waxes were evaluated. Wheat bran, the main byproduct of flour milling, was used as filler to reduce the final cost of the PHBV-based composites and, in the same time, to find a potential valorization to this agro-food by-product, widely available at low cost. The results showed that the wheat bran powder did not act as reinforcement, but as filler for PHBV, due to an unfavorable aspect ratio of the particles and poor adhesion with the polymeric matrix, with consequent moderate loss in mechanical properties (tensile strength and elongation at break). The surface treatment of the wheat bran particles with waxes, and in particular with beeswax, was found to improve the mechanical performance in terms of tensile properties and impact resistance of the composites, enhancing the adhesion between the PHBV-based polymeric matrix and the bran fibers, as confirmed by predictive analytic models and dynamic mechanical analysis results.

The agricultural raw industry generates large amounts of annually by- -products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and ?-amylase from these raw materials using Paenibacillus sp. that would reduce the costs. Thus, in this paper simultaneous cellulase (CMC-ase and avicelase) and ?-amylase production using barley bran and the application of the natural isolate Paenibacillus chitinolyticus CKS1 and potential enzymes in the hydrolysis process was studied. Response surface methodology was used to obtain the maximum enzyme activity (CMC-ase 0.405 U mL-1, avicelase 0.433 U mL-1 and ?-amylase 1.594U mL-1). Scanning electron microscopy showed degradation of the lignocellulosic?starch structure of barley bran after fermentation. The CKS1 bacterial supernatant, which contains cellulases and ?-amylase, could hydrolyze cotton fibres and barley bran, respectively. The main products after enzymatic hydrolysis of cotton fibres and barley bran, glucose (0.117 g gmat -1) and maltose (0.347 g gmat -1), were quantified by high performance liquid chromatography (HPLC). The produced enzymes could be used for hydrolysis of cotton fabric and barley bran to glucose and maltose, respectively. Application of simultaneous enzymes production using an agricultural by-product is economically and environmentally accepted and moreover, valuable biotechnological products, such as glucose and maltose, were obtained in this investigation.

Cereal by-products (wheat germ, maize bran–germ mixture, rye bran, and wheat bran) from the flour milling industry were characterized for their nutritional value and chemical composition, as well as for antioxidant and antibacterial activities. Carbohydrates (including sucrose) were the major nutritional constituents (56.35–78.12 g/100 g dw), followed by proteins (11.2–30.0 g/100 g dw). The higher energy value (432.3 kcal/100 g dw) was presented by the wheat germ. This by-product also presented the highest citric acid content (0.857 g/100 g dw), the most abundant organic acid detected. Unsaturated fatty acids predominated in all samples given the high content of linoleic (53.9–57.1%) and oleic (13.4–29.0%) acids. Wheat germ had the highest levels of tocopherols (22.8 mg/100 g dw) and phenolic compounds (5.7 mg/g extract, with a high apigenin-C-pentoside-C-hexoside content). In turn, while the wheat bran extract was particularly effective in inhibiting the formation of thiobarbituric acid reactive substances (TBARS), the rye bran extract was the only sample capable of protecting erythrocytes from oxidative hemolysis. Regarding antibacterial properties, in general, the lowest minimum inhibitory concentrations were observed against methicillin-resistant Staphylococcus aureus. These results highlight the characterized by-products as sustainable ingredients for the development of novel bakery and functional food products and contribute to a better bioresource-use efficiency and circularity.

Abstract The objective of this study was to develop a bioplastic from industrial by-products. Commercial defatted rice bran (DRB) was extruded with 0–30% kraft lignin (KL) as a filler and 30% glycerol as a plasticizer. Firstly, the effect of extrusion temperature on the plasticized DRB’s processability was determined. Increasing the die extrusion temperature from 100°C to 150°C improved the extrudability by decreasing the die pressure and motor current. Subsequently, the effect of KL on plasticized DRB was studied. The addition of 10–30% KL improved DRB processability. The addition of 30% KL markedly lowered the die pressure in comparison to using a 150°C extrusion temperature. Moreover, KL addition decreased DRB viscosity determined by a capillary rheometer. These results were coherent with a decreased storage modulus in a rubber state and an increased tan δ height determined by a dynamic mechanical thermal analyzer (DMA). However, n values of DRB with 10–30% KL could not be explained by a simple mixing rule. This may be attributed to the interaction between DRB and KL, as shown by Fourier transform infrared (FTIR) spectra. KL addition increased Young’s modulus and the glass transition temperature (Tg) of plasticized DRB. Therefore, blending DRB with KL is an effective way to improve polymer flowability at the processing temperature and mechanical properties at ambient temperature.

Agricultural wastes are lignocellulosic biomasses that contain high mineral and nutrient contents. This waste can be used as a raw material in industrial enzyme production by microbial fermentation. Phytase is an important enzyme used in animal feed to enhance the amount of phosphorus available for the growth and overall health improvement of monogastric animals. Fungi offer high potential as an effective source in the production of various extracellular enzymes. In this study, the production of lignocellulolytic enzymes (endoglucanase and xylanase) and phytase by a thermophilic fungus, namely Thermoascus aurantiacus strain SL16W, was evaluated using sixteen different Thai agricultural forms of waste under conditions of high temperature (45 °C). Semi-solid state fermentation was used in the production experiments. The results of this study reveal that the highest phytase activity (58.6 U/g substrate) was found in rice bran, whereas the highest degrees of activity of endoglucanase and xylanase were observed in wheat bran and red tea leaves at 19 and 162 U/g substrate, respectively. Consequently, the optimal conditions for phytase production of this fungus using rice bran were investigated. The results indicate that the highest phytase yield (58.6 to 84.1 U/g substrate) was observed in rice bran containing 0.5% ammonium sulfate as a nitrogen source with 10 discs of inoculum size at a cultivation period of 9 days at 45 °C and moisture content of 95%. Notably, the phytase yield increased by 1.71-fold, while endoglucanase and xylanase were also increased by 1.69- and 1.12-fold, respectively. Furthermore, the crude enzyme obtained from the optimal condition was extracted. The crude enzyme extract was then separately added to red tea leaves, rice straw, corncobs, palm residue, and peanut husks. Subsequently, total reducing sugar and phosphorus contents were determined. The results indicate that the highest level of reducing sugar (122.6 mg/L) and phosphorus content (452.6 mg/L) (p < 0.05) were obtained in palm residue at 36 and 48 h, respectively, after the addition of the crude enzyme extract. This study has provided valuable information on a potentially eco-friendly way to valorize agricultural waste into value-added products as industrial enzymes.

Solid state fermentation (SsF) is recognized as a suitable process for the production of enzymes using organic residues as substrates. However, only a few studies have integrated an evaluation of the feasibility of applying enzymes produced by SsF into subsequent hydrolyses followed by the production of target compounds, e.g., lactic acid (LA), through submerged-liquid fermentations (SmF). In this study, wheat bran (WB) was used as the substrate for the production of enzymes via SsF by Aspergillus awamori DSM No. 63272. Following optimization, cellulase and glucoamylase activities were 73.63 ± 5.47 FPU/gds and 107.10 ± 2.63 U/gdb after 7 days and 5 days of fermentation, respectively. Enzymes were then used for the hydrolysis of the organic fraction of municipal solid waste (OFMSW). During hydrolysis, glucose increased considerably with a final value of 19.77 ± 1.56 g/L. Subsequently, hydrolysates were fermented in SmF by Bacillus coagulans A166 increasing the LA concentration by 15.59 g/L. The data reported in this study provides an example of how SsF and SmF technologies can be combined for the valorization of WB and OFMSW.

<em>The study was conducted in Urban Community of Niamey at modern and semi-modern farms provided an overview use of agro-industrial by-products in animal feed. Among 57 farms only 17 farms, including 10 beef farms, 2 sheep farms and 5 poultry farms were systematically surveyed. All farm managers are men. 60 and 33% are respectively officials at the level of poultry farms and ruminant farms. Farmers make up 25%, all of which own beef farms. There is also a predominance of adults, 60% at poultry level and 58.33% at ruminant farms. We note the use of a variety of agro-industrial by-products in animal feeds, in this case by-products derived from vegetable processing (wheat bran, exfoliated cotton cake) and animal processing (fish and fish meal ...). There are also some concentrates for poultry feed. Agribusiness by-products are increasingly used in urban livestock production but their valorization needs to be improved.</em>

Agriculture is facing many challenges, such as climate change, drought, and salinity, which call for urgent interventions for fast adaptation and crop diversification. The introduction of high-value and stress tolerant crops such as quinoa would be a judicious solution to overcome constraints related to abiotic stress and to increase land productivity and farmers’ incomes. The implementation of quinoa in Morocco has not been supported by a full valorization program to control the quality of quinoa seeds. The novelty of this work is to assess the pearling operation as an efficient method of saponins removal as well as the determination of total residual saponins. This study aimed to evaluate the effects of several pearling durations on nutrient and saponin content of quinoa seeds of three tested varieties (Puno, Titicaca, and ICBA-Q5). Five pearling durations were tested (0, 2, 4, 6, 7, and 8 min) using a locally manufactured pearling machine. The results indicated that a pearling duration of two minutes was enough to reduce total saponin content from 0.49% to 0.09% for Puno variety, from 0.37% to 0.07% for Titicaca variety, and from 0.57% to 0.1% for ICBA-Q5 variety. Our results showed that pearling slightly reduced protein, total fat, and moisture contents for all varieties except for Puno, where total fat content slightly increased with the pearling. Puno variety had the highest seed content in terms of protein and total fat; the ICBA-Q5 variety had the lowest. Titicaca had the highest bran content in terms of protein and total fat, ICBA-Q5 had the highest bran content in terms of ash and the lowest bran content in terms of protein and total fat, and Puno had the lowest bran content in terms of ash. Pearling had no significant effect on macronutrient contents in the processed seed, but it resulted in a very highly significant difference for most of them in the bran except for Mg and S. Regarding seed content in terms of micro-nutrients, statistical analysis showed significant differences between varieties in terms of Zn, Cu, and Mn contents, but no significant difference was recorded for Fe or B. Pearling had no significant effect on seed micronutrient contents. Therefore, to retain maximum nutritional content in the quinoa and maintain quinoa integrity, it is necessary to limit the pearling duration of quinoa to two minutes, which is enough to reduce saponin content below the Codex Standard threshold (0.12%).

Laccase is increasingly adopted in diverse industrial and environmental applications, due to its readily accessible requirements for efficient catalytic synthesis and biotransformation of chemicals. However, it is perceived that its industrial production might incur some unfavorable overhead, which leads to expensive market products, and the corresponding negative environmental feedback, due to the use of capital-intensive and precarious chemicals. To this end, this study was designed to evaluate the performance indicators of the valorization of wheat bran by a novel Jb1b laccase and its subsequent application in waste minimization and water management, on a laboratory scale. Optimal Jb1b laccase was produced in submerged fermentation medium containing wheat bran, an agroindustrial residue, through response surface methodology (RSM) algorithm, and was applied in dye decolorization and denim bioscouring, respectively. Results showed that the resultant enzyme manifested unique biochemical properties, such as enhanced tolerance at certain physicochemical conditions, with a residual activity of at least ca. 76%. Furthermore, phenomenally high concentrations of synthetic dyes (0.2% w v−1) were decolorized over 56 h, and a 6 h mediator-supported simultaneous denim bleaching and decolorization of wash effluent was observed. The sustainability of the production and application processes were inferred from the reusability of the fermentation sludge as a potential biofertilizer, with subsequent prospects for the biostimulation and bioaugmentation of contaminated soils, whereas the decolorized water could be adopted for other uses, amongst which horticulture and forestry are typical examples. These phenomena therefore authenticate the favorable environmental feedbacks and overhead realized in this present study.

Valorization of wheat bran (WB) into new high-value products is of great interest within the framework of sustainability and circular economy. In the present study, we utilized a multi-step approach to extract nutraceutical compounds (phenolic acids) from WB and improved its antioxidant and anti-inflammatory properties through using sequential hydrothermal and enzymatic hydrolysis. Thirteen commercial glycosidases differing in their specific activity were screened and compared for hydrolytic efficiency to release monosaccharides, ferulic acid, and diferulic acid. Ultraflo XL was selected as the desired enzyme treatment on the basis of its higher WB solubilization, as well as its monosaccharide and phenolic acids yields. The relationships between better hydrolytic performance of Ultraflo XL and its particular activity profile were established. To determine the optimum conditions for Ultraflo XL treatment, we tested different factors (solvent pH, incubation temperature, and time) under 15 experiments. A multicomponent analysis (MCA), including central composite design, model fitness, regression coefficients, analysis of variance, 3D response curves, and desirability, was used for processing optimization. A beneficial effect of autoclave treatment on the release of phenolic compounds was also evidenced. The results of MCA showed involvement of linear, quadratic, and interactive effects of processing factors, although solvent pH was the main determinant factor, affecting enzymatic extraction of phenolics and bioactivity of hydrolysates. As compared to control WB, under optimized conditions (47 °C, pH = 4.4, and 20.8 h), WB hydrolysates showed 4.2, 1.5, 2, and 3 times higher content of ferulic acid (FA) and capacity to scavenge oxygen radicals, chelate transition metals, and inhibit monocyte chemoattractant protein-1 secretion in macrophages, respectively. These approaches could be applied for the sustainable utilization of WB, harnessing its nutraceutical potential.

The present study aims to valorize the Typha australis stems, through second-generation bioethanol production using enzymatic hydrolysis and fermentation. The monitoring of fermentation kinetics parameters, such as pH, density, length of fermentation, and the Brix, indicated a great variability of these parameters during the fermentation process of the must with three Saccharomyces cerevisiae strains, such as Angel brand Thermal-tolerant alcohol active dry yeast, Angel brand super alcohol active dry yeast and Angel super alcohol active dry yeast in the presence of urea (CON2H4) used as a growth factor. The distillation of musts after fermentation has yielded ethanol extraction rate (% v / v at 20 ° C) between 4.95and 44.93 after fractional distillation. The best performance in ethanolic bioconversion was recorded with Angel brand super alcohol active dry yeast. This Saccharomyces cerevisiae strains could be used as effective ferments, in perspective of intensive production of second-generation bioethanol with Typha australis stems.

The contemporary significance of branding as a source of value is explored by situating the creation and valorization of brand equity within ‘the full circuit of capital’. Conceived as a form of co-production occurring in the sphere of circulation (as well as production), brand-building is connected to: the surpluses generated by the labour of user-consumers as well as the designers and producers of branded products and services; the realization of surplus through control of revenues derived from sales of these products and services and the appropriation of surpluses, including the conversion of brand equity into brand value after deduction of costs. Contemporary investment in branding is related to the financialization of brands as intangibles that make a growing contribution to market capitalization. By attending to multiple facets of the circuit of capital, including the co-production brand equity by user-consumers, some pointers are proposed for developing a more ‘joined-up’ view of the ‘bigger picture’ of contemporary capitalist reproduction.

The folk artistry of Serbia is rich in spiritual values tied to customs, celebrations, music, song, dance, games, stories and legends, and this kind of cultural heritage is presented through numerous festivals, events and tourist manifestations. In 2012, the network for the safeguarding of intangible cultural heritage was formed, comprised of the National committee for intangible cultural heritage, the Commission for admission into the registry of intangible cultural heritage, a network of coordinators and the Center for intangible cultural heritage of Serbia. These institutions have chosen 6 elements of intangible cultural heritage, out of 27 suggestions: the slava, the Đurđevdan ritual, the kolo dance, singing accompanied by gusle, Slovakian naive painting, the custom of making and lighting farmers’ candles, Pirot carpet weaving, and Zlakusa pottery as elements of cultural heritage which reflect the national and cultural identity of the Serbian people, and Slavic minorities. These elements of intangible cultural heritage have a certain tourism potential and can represent an important factor in the forming of the tourist brand of Serbia. In order to determine the importance of the 27 suggestions of intangible cultural elements of Serbia, an analysis was conducted, using an adapted form of the Hilary du Cros method of tourist valorization.

The slaughterhouse of Cotonou and the surfaces of slaughtering of Porto-Novo, Abomey-Calavi, Sèmè-Kpodji and Ouidah constitute sources of animal solid matter flow in Large Nokoué. Within the framework of this research, it is refers to the contents of paunches considered for their potential of valorization in the production of biogas and the compost. Then, the quantitative evaluation their layers is a contribution to the efficient use of those as resources or raw materials, for a planning of future management. The methodological approach used is centered on the document retrieval, the datagathering by measurements or weighing of the roughs weight of contents of paunch of the animal species using balance of brand CAMRY as well as recovery of the statistics of slaughtering in the structures in charge of the breeding and the services of inspection of the activities of slaughtering units. The data obtained were treated then the analyzed results. The sample size selected is of 50 individuals of species cattle and 50 individuals of species of caprine sheep. The data analysis was analyzed, inter alia, thanks to software SPSS version 17.0 was used for the statistical analyses. It comes out from this research that each shot down cattle generate 48.5612 kg of waste (contained digestive). It is advisable to recall that the majority of the cattle taken as sample is race zebu and bull-fighting. As for the sheep and goats, each animal generates a quantity of approximately 4.0364 kg of waste. With this average of 48.5612 kg of contents of bovine paunch, and 4.0364 kg for the sheep and goats, the layer of contents the digestive ones was estimated at 1060 tons for the year 2011, and at 1298 tons for the year 2015 at the level of Large Nokoué. If this trend is maintained, this layer could border 2011 tons by 2030. The evaluation of the layers of contents of paunch produces by the activities of demolition the sector of the study regarded as largest parts of the fractions which may undergo beneficiation of the livestock wastes takes part in the installation of strategies of perpetuation of the actions of treatment and valorization within the framework of a sector.

The tourism market, as any other economic sector, demands organisation and competition. As a consequence, integrated strategies are necessary in order to improve and qualify the supply, in terms of receptivity, resource usability, additional services and marketing. The impending metropolitan area, for its intrinsic features, could play a double role in the tourism sector as both destination and hub for the whole regional territory, as it is rich in natural resources although simultaneously lacking in services. A correct valorization of these territories needs a targeted tourism focused on blending "knowledge", connected to history, and "taste", as testified by the rural tradition. The territory needs to be seen as a product to be sold, complying to the rules of territorial marketing, supporting best practice experiences as “Le reggine dei Sapori” a territorial brand created to maximize agro-food products, and "Strada dei vini e dei sapori della Locride”, that turned the territory into a system that hands down the knowledge and tradition of "Magna Graecia" and its typical products in the perspective that “ Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs ”.

Vine pruning residues are by-products of the wine industry that have not received much attention in the past, in spite of being rich in bioactive compounds. In this study, we aimed to test whether an ohmic extract of vine pruning residue (VPE) has anti-colorectal cancer (CRC) properties, and whether responses differ according with cell’s mutation profile. VPE decreased human CRC cell proliferation, accompanied by DNA effects and cell cycle modulation. VPE also increased cell sensitivity to the chemotherapeutic drug 5-FU. Our results suggest that tumors harboring BRAF mutations may be more responsive to VPE than KRAS mutated tumors. These effects of the extract were not completely reproduced by the most abundant constituents tested individually at the concentrations present in the effective dose of VPE. Globally, our results indicate that VPE, a polyphenol enriched extract produced by ohmic heating of vine pruning residue, has anti-colorectal cancer potential, including sensitizing to a chemotherapeutical drug, and its use in functional foods or nutraceuticals could be exploited in personalized anti colorectal cancer dietary strategies. Valorization of this lignocellulosic residue should encourage bio-waste recycling, adding value to this agricultural by-product and promoting the sustainable use of natural resources.

In this paper, we analyze the consumption habits and perceptions of Brazilians and Americans regarding the consumption, preparation and handling of the coffee product and its packaging, in order to better think about translating the packaging of coffee produced in southern Minas Gerais to the USA market. Through bibliographic research and other resources, information such as preparation, reasons for consumption, and place of consumption were compared between the two populations to understand if there were relevant cultural differences. The packaging of eight coffee brands, four from each country, was also compared in order to notice any differences and similarities between them. The results show that there are indeed differences between the two cultures, both in their habits and in their packaging. Some examples are the valorization of the semantic field of coffee in Brazilian packaging, and the preference for quick methods of brewing the product for the Americans. We conclude that any translation of Brazilian coffee for the American public must consider these differences. Finally, we present some possibilities for packaging translation, using for this the idea of country brand and its influences on consumers, as well as the concepts of Localization, Intersemiotic Translation and Paratranslation.

Neuroinflammation constitutes a normal part of the brain immune response orchestrated by microglial cells. However, a sustained and uncontrolled production of proinflammatory factors together with microglial activation contribute to the onset of a chronic low-grade inflammation, leading to neuronal damage and cognitive as well as behavioral impairments. Hence, limiting brain inflammatory response and improving the resolution of inflammation could be particularly of interest to prevent these alterations. Dietary n-3 long chain polyunsaturated fatty acids (LC-PUFAs) and low molecular weight peptides are good candidates because of their immunomodulatory and proresolutive properties. These compounds are present in a fish hydrolysate derived from marine-derived byproducts. In this study, we compared the effect of an 18-day supplementation with this fish hydrolysate to a supplementation with docosahexaenoic acid (DHA) on lipopolysaccharide (LPS)-induced inflammation in mice. In response to peripherally injected LPS, the fish hydrolysate supplementation decreased the hippocampal mRNA expression of the proinflammatory cytokines IL-6 (p < 0.001), IL-1β (p = 0.0008) and TNF-α (p < 0.0001), whereas the DHA supplementation reduced only the expression of IL-6 (p = 0.004). This decline in proinflammatory cytokine expressions was associated with an increase in the protein expression of IκB (p = 0.014 and p = 0.0054 as compared to the DHA supplementation and control groups, respectively) and to a modulation of microglial activation markers in the hippocampus. The beneficial effects of the fish hydrolysate could be due in part to the switch of the hippocampal oxylipin profile towards a more anti-inflammatory profile as compared to the DHA supplementation. Thus, the valorization of fish byproducts seems very attractive to prevent and counteract neuroinflammation.

AbstractLignin nano/microparticles have recently attracted growing interest for various value-additive applications of lignin, especially encapsulation. In this study, in order to establish a highly efficient and highly productive preparation process to effectively utilize technical lignin, a brand-new, slow and exhaustive solution evaporation process following a simple, self-assembly principle was developed using industrial softwood kraft lignin (SKL) from a starting acetone-water (80/20, v/v) solution to recover 100% of the lignin as homogeneous and well-shaped microspheres. The prepared microspheres had a typical average diameter of 0.81 ± 0.15 μm and were hollow with very thin shells (of nanoscale thickness). Based on this developed technique, encapsulation of urea by these lignin microspheres was directly achieved using the same process as hollow lignin microspheres with urea attached to the outside and entrapped inside of the wall. Two distinct urea release rates were observed for the urea-encapsulated microspheres: a fast release of the urea outside the shell wall and a slow (controlled) release of the urea inside the shell wall. The encapsulation efficiency was as high as 46% of the trapped urea as encapsulated inside the lignin microspheres. The slow and exhaustive solution evaporation procedure reported here is a simple and straightforward method for the valorization of industrial kraft lignin as hollow microspheres with controllable, homogeneous and desired morphologies, and especially for the direct preparation of lignin-based encapsulating fertilizers for controlled release.

Objective of the study: The objective of this research was to analyze how the processes of creation and appropriation of value are manifested in a horizontal agribusiness networkMethodology / approach: A case study was carried out in the Cerrado Mineiro Region (CMR) in which documentary research and interviews were used as source, whose data were analyzed through content analysis by frequency. Originality / Relevance: There is little evidence in the literature about studies that explore processes of joint value creation and appropriation in horizontal networks. In view of this gap, the study proceeds by individually addressing the processes of creation and appropriation of value considering the nature of cooperation of the networks.Main results: In relation to the results achieved, CMR creates value in cost reduction, differentiation by product, market expansion, expertise in the production of coffee, differentiation, dissemination and strengthening of the brand. Regarding the appropriation of value, CMR appropriates itself for the commercialization of potential quality coffee, the learning process, the premium paid in the cooperative's coffee, the valorization of the producer and for having a unique way for the production of coffee.Theoretical / methodological contributions: Among the main contributions of this study, the individual analysis highlights the processes of creation and appropriation of value applied to horizontal networks. The considerations reinforce the fine line between the processes of creation and appropriation of relational value. That is, in addition to developing internal competencies and essential skills for the creation and appropriation of value, organizations must devise strategies to achieve a balance between these processes.

Reversing decades of fear and neglect as no-go zones for outsiders, Rio de Janeiro’s most iconic favela communities have become tourist attractions offering a glimpse of the purported “other side” of Brazilian society as well as panoramic vistas over the Marvelous City. Since 2010, tourism has become a vehicle and justification for security, infrastructure, and capacity-building projects in Rio’s favelas. Promoted as an exemplary favela in this social uplift scheme, Santa Marta has received thousands of tourists per year. In an unprecedented step, Santa Marta guides organized themselves into a committee to collectively manage the tourism enterprise and to promote themselves as a brand of community-based tourism in contradistinction to outside commercial tour operators. Their authority and authenticity as local experts hinge on the emergent perception of the favela itself as a resource and that their labor makes that value economically productive. This article analyzes the work of these guides as cultural brokers to think through the semiotically overdetermined yet shifting status of the favela as space of cultural alterity from the perspective of those who are both targets and agents of its transformation. Exploring how community-based guides have emerged as political and economic brokers, this article suggests that their performances as local experts, as well as their modes of organizing, shape tensions and contradictions of the favela as a commodified place. It demonstrates how collectivist and competitive interests among guides embody differing perspectives on state intervention in their community. The discussions and conflicts among tour guides themselves embody the tensions over the future of communities long marginalized by state and capital yet suddenly targeted for economic investment and cultural valorization.

Background & Objective:Crude glycerol (Glol), used as substrate for screening eleven natural Yarrowia lipolytica strains in shake-flask experiments. Aim of this study was to assess the ability of the screened strains to produce biomass (dry cell weight; X), lipid (L), citric acid (Cit), mannitol (Man), arabitol (Ara) and erythritol (Ery), compounds presenting pharmaceutical and biotechnological interest, in glycerol-based nitrogen-limited media, in which initial glycerol concentration had been adjusted to 40 g/L.Methods:Citric acid may find use in biomedical engineering (i.e. drug delivery, tissue engineering, bioimaging, orthopedics, medical device coating, wound dressings). Polyols are considered as compounds with non-cariogenic and less calorigenic properties as also with low insulin-mediated response. Microbial lipids containing polyunsaturated fatty acids (PUFA) are medically and dietetically important (selective pharmaceutical and anticancer properties, aid fetal brain development, the sight function of the eye, hormonal balance and the cardio-vascular system, prevent reasons leading to type-2 diabetes, present healing and anti-inflammatory effects).Results:All strains presented satisfactory microbial growth (Xmax=5.34-6.26 g/L) and almost complete substrate uptake. The principal metabolic product was citric acid (Citmax=8.5-31.7 g/L). Production of cellular lipid reached the values of 0.33-0.84 g/L. Polyols were also synthesized as strain dependent compounds (Manmax=2.8-6.1 g/L, Aramax ~2.0 g/L, Erymax= 0.5-3.8 g/L). The selected Y. lipolytica strain ACA-DC 5029 presented satisfactory growth along with synthesis of citric acid and polyols, thus, was further grown on media presenting an increased concentration of Glol~75 g/L. Biomass, lipid and citric acid production presented significant enhancement (Xmax=11.80 g/L, Lmax=1.26 g/L, Citmax=30.8 g/L), but conversion yield of citric acid produced per glycerol consumed was decreased compared to screening trials. Erythritol secretion (Erymax=15.6 g/L) was highly favored, suggesting a shift of yeast metabolism from citric acid accumulation towards erythritol production. Maximum endopolysaccharides (IPS) concentration was 4.04 g/L with yield in dry weight 34.2 % w/w.Conclusion:Y. lipolytica strain ACA-YC 5029 can be considered as a satisfactory candidate grown in high concentrations of crude glycerol to produce added-value compounds that interest pharmaceutical and biotechnology industries.

Sustainability is to promote economic growth that generates equitable wealth for all without harming the environment, becoming one of the objectives that serve as a starting point for many place branding strategies. Cultural heritage, environmental sustainability, and the valorization of the territory are nowadays unavoidable elements to sustain brands. This research analyzes the transmission of place branding values through experiential events, as a formula for business improvement according to the principles of sustainable development. The research is focused on the case of wine in British Columbia (Canada). The methodology applied was based on a theoretical framework as a starting point for the study. From there, on the one hand, an analysis of the contents of the events carried out by the winegrowers of British Columbia during the harvest months in 2019 and 2020 has been carried out. On the other hand, interviews were conducted with relevant professionals and academics in the sector in order to determine the extent to which they meet the needs of promotion of the site, taking into account the impact on the sustainability of the territory. The results show the link between the events and the territory brand, which is a means to generate growth through wine tourism promoted by the wineries, thus revaluing the winegrowing landscape and, in general, the traditions of the place, among others. There is also a need to look for strategies that seek collaboration between the public and private sectors to improve the creation of integrated events that transmit the branding values of the place. Events are a tool to generate territory branding and can, if well-conceived, contribute to the sustainable development goals (SDGs). In the case study, the results show that the vast majority of events organized by BC wineries aim to promote place branding within the framework of sustainability. A methodology that could be applicable to other territories and countries.

A partir de una investigación etnográfica sobre la patrimonialización y las estrategias de valorización de productos con identidad cultural, este artículo analiza el desarrollo de la campaña publicitaria y la propuesta de responsabilidad social empresarial “En busca del orgullo perdido”. Examina las distintas fases del desarrollo de este proyecto y se detiene en el análisis de la experiencia de intervención de los mercaderistas y diseñadores responsables de la campaña en una comunidad de artesanos indígenas del Amazonas colombiano. Muestra cómo la búsqueda de asociatividad y generación de marca colectiva, sin detenerse a considerar el punto de vista del análisis social, terminó proyectando valores y modelos de mercado que antes que exaltar el orgullo del trabajo artesanal reprodujeron los prejuicios más obvios sobre las bondades del mercado. El caso analizado evidencia los problemas que estrategias de mercadeo corporativo pueden generar al desatender el espacio social en el que se proponen.

Sago processing wastewater was assessed for their suitability as growth substrates using oleaginous yeasts, for the production of a useful enzyme (amylase) under submerged fermentation (SmF). Sago wastewater (pH was adjusted to 6) containing starch concentration (10% w/v) were inoculated with yeast strain and incubated at 30ºC for 10 d in an incubator shaker (150 rpm). The results of the amylase activity of oleaginous yeast and in its substratum SWW were compared with the different processing wastes (potato peel, banana peel, cassava peel, corn residue, rice husk, wheat bran, yam peel and barley husk) and oleaginous yeasts (Rhodotorula mucilaginosa, Saccharomyces pastorianus, Lipomyces starkeyi and Rhodotorula glutinis). Compared to other oleaginous yeast, our yeast strain found to produce higher amylase activity of 1.51 IU mL-1. Furthermore, SWW produced more amylase activity than the other compared wastes. This research finding illustrates the environmental friendly and alternate use of sago processing wastewater, towards their valorization as substrates for valuable enzymes and chemical production.

The processing of agricultural products into value-added food products yields numerous by-products or waste streams such as pomace (fruit and vegetable processing), hull/bran (grain milling), meal/cake (oil extraction), bagasse (sugar processing), brewer's spent grain (brewing), cottonseed meal (cotton processing), among others. In the past, significant work in exploring the possibility of the utilization of these by-products has been performed. Most by-products are highly nutritious and can be excellent low-cost sources of dietary fiber, proteins, and bioactive compounds such as polyphenols, antioxidants, and vitamins. The amount of energy utilized for the disposal of these materials is far less than the energy required for the purification of these materials for valorization. Thus, in many cases, these materials go to waste or landfill. Studies have been conducted to incorporate the by-products into different foods in order to promote their utilization and tackle their environmental impacts. Extrusion processing can be an excellent avenue for the utilization of these by-products in foods. Extrusion is a widely used thermo-mechanical process due to its versatility, flexibility, high production rate, low cost, and energy efficiency. Extruded products such as direct-expanded products, breakfast cereals, and pasta have been developed by researchers using agricultural by-products. The different by-products have a wide range of characteristics in terms of chemical composition and functional properties, affecting the final products in extrusion processing. For the practical applications of these by-products in extrusion, it is crucial to understand their impacts on the qualities of raw material blends and extruded products. This review summarizes the general differences in the properties of food by-products from different sources (proximate compositions, physicochemical properties, and functional properties) and how these properties and the extrusion processing conditions influence the product characteristics. The discussion of the by-product properties and their impacts on the extrudates and their nutritional profile can be useful for food manufacturers and researchers to expand their applications. The gaps in the literature have been highlighted for further research and better utilization of by-products with extrusion processing.

Purpose This paper aims to contribute to the augmenting literature on consumer brand engagement (CBE) in social media brand communities (SMBCs) by offering the model of the depth of brand engagement funnel (DOBEF). The model is intended to complement the multi-dimensional conceptualization of CBE in the extant consumer behaviour literature and to critically address some of its foundational tenets. Design/methodology/approach A computer-mediated discourse analytic (CMDA) approach is adopted while using a mixed methods research design whereby qualitative data are quantified with a view to enhancing the robustness of the interpretive procedure. The data comprise 170 UGC posts stemming from three fast-moving consumer goods brands’ SMBC threads. Additionally, a netnographic approach is adopted in data collection, while data analysis/synthesis proceeds with the application of the laddering technique with the aid of the computer-aided qualitative discourse analytic CAQDAS software atlas.ti. Findings The bulk of user-generated content (UGC) in the scrutinized brand initiated thematic threads were found to be relevant, albeit negatively valenced or lacking in relevance altogether. This behavioural response pattern to brand initiated themes poses significant constraints to the level and quality of CBE. Multi-dimensional engagement across the DOBEF’s strata was found to be scarce, while engagement diminishes gravely as the upper layers of the model are reached. Research limitations/implications By conducting analyses on coded data alongside DOBEF’s strata, rather than treating consumer comments as raw data, the narrowing down of the semantic focus of posted comments in a thread-specific fashion is enabled, thus meeting the narrow contextualization criterion that is lacking from various studies in the extant literature. Practical implications By shifting focus in identifying CBE levels in SMBCs from attitudinal/behavioural antecedents/outcomes towards the content of the interaction, a nuanced perspective is offered as regards the depth of interaction, while addressing posted comments not only in terms of valencing, but even more importantly of valorization. Social implications By attending closely to incidents of negative brand engagement, and by dimensionalizing engagement along the funnel’s strata, a more nuanced understanding of territories where brand communities contribute to the dilution, rather than the enhancement of brand equity was obtained. Originality/value This is the first paper that discusses engagement on the grounds of deeply-laden consumer axiologies and the degree to which these are congruent with specific brand initiated thematic threads in SMBCs. It is anticipated that the discourse analytic (DA) approach that is adopted here will instigate further research that attends to UGC in a small-data, highly context-specific, rather than a big-data vein.

One of the commonplace and myopic reactions to the rise of televisual time-shifting via video-on-demand, DVD rental services, illegal downloads, and streaming media was to decree “the death of the communal television experience”. For many, new forms of watching television unconstrained by time-bound, regularly scheduled programming meant the demise of the predominant form of media liveness that existed commercially since the 1950s. Nevertheless, as time-shifting practices evolved, so have attendant notions of televisual temporality—including changing forms of liveness, shared experience, and the plastic and flexible nature of new viewing patterns (Bury & Li; Irani, Jefferies, & Knight; Turner; Couldry). Although these temporal conceptualisations are relevant to streaming media, in the few years since the launch of platforms such as Netflix, Hulu, and Amazon, what it means “to stream” has rapidly expanded. Social media platforms like Twitter, Facebook, Snapchat, YouTube, and TikTok allow users to record, share, and livestream their own content. Not only does social media add to the growing definition of streaming, but these streaming interactions are also predominately mobile (Munson; Droesch). Taken together, a live and social experience of time via audio-visual media is not lost but is instead reactivated through the increasingly mobile nature of streaming. In the following article, I examine how mobile streaming media practices are part of a construction of shared temporality that both draws upon and departs from conceptualisations of televisual and fixed streaming liveness. Accordingly, HQ Trivia—a mobile-specific streaming gameshow app launched in August 2017—demonstrates novel attempts at reimagining the temporally-bound live televisual experience while simultaneously offering new monetisation strategies via mobile streaming technologies. Through this example, I argue that pervasive Web-connectivity, streaming platforms, data collection, mobile devices, and mobile streaming practices form arrangements of valorisation that are temporally bound yet concomitantly mobile, allowing new forms of social cohesion and temporal control.A Brief History of Televisual TemporalityTime is at once something infinitely mysterious and inherently understood. As John Durham Peters concisely explains, “time lies at the heart of the meaning of our lives” (175). It is precisely due to the myriad ontological, phenomenological, and epistemological dimensions of time that the subject has long been the focus of critical inquiry. As part of the so-called spatial turn, Michel Foucault argues that theory formerly treated space as “the dead, the fixed, the undialectical, the immobile. Time, on the contrary, was richness, fecundity, life, dialectic” (70). While scholarly turns toward space and later mobility have shifted the emphasis of critical inquiry, time is not rendered irrelevant. For example, Doreen Massey defines spaces as the product of interrelations, as sphere of possibility and heterogeneous multiplicity, and as always under construction (9). Critical to these conceptualisations of space, then, is the element of time. Considering space not as a static container in which individual actors enter and leave but instead as a production of ongoing becoming demonstrates how space, mobility, and time are inexorably intertwined. Time, space, and mobility are also interrelated when it comes to conversations of power. Judy Wajcman and Nigel Dodd contend that temporal control is related to dynamics of power, in that the powerful are fast and the powerless slow (3). Questions of speed, mobility, and the control of time itself, however, require attention to the media that help construct time. Aspects of time may always escape human comprehension, yet, “Whatever time is, calendars and clocks measure, control, and constitute it” (Peters 176). Time is a sociotechnical construction, but temporal experience is bound up in more than just time-keeping apparatuses. Elucidated by Sarah Sharma, temporalities are not experienced as uniform time, but instead produced within larger economies of labor and temporal worth (8). To reach a more productive understanding of temporalities, Sharma offers power-chronography, which conceptualises time as experiential, political, and produced by social differences and institutions (15). Put another way, time is an experience structured by the social, economic, political, and technical toward forms of social cohesion and control.Time has always been central to the televisual. Though it is often placed in a genealogy with film, William Uricchio contends that early discursive imaginings and material experiments in television are more indebted to technologies such as the telegraph and telephone in promising live and simultaneous communication across distances (289-291). In essence, film is a technology of storage, related to 18th- and 19th-century traditions of conceptualising time as fragmented; the televisual is instead associated with the “contrasting notion of time conceived as a continuous present, as flow, as seamless” (Uricchio 295). Responding to Uricchio, Doron Galili asserts that the relationship between film and television is dialectical and not hierarchical. For Galili, the desire for simultaneity and storage oscillates—both are present, both remain separate from one another. It is the synthesis of simultaneity and storage that allows both to operate together as a technological and mediated vision of mastering time. Despite disagreements regarding how best to conceptualise early film and television, it is clear that the televisual furthered a desire for spatial and temporal coordination, liveness, and simultaneity.In recent years, forms of televisual “time-shifting” allow viewers to escape temporally-bound scheduling. In what is commonly periodised as TVIII, the proliferation of digital platforms, video-on-demand, legal and illegal downloads, and DVD players, and streaming media displaced more traditional forms of watching live television (Jenner 259). It is important to note that while streaming is often related to the televisual, the televisual-to-streaming shift is not a clean linear evolution. Televisual-style content persists in streaming, but streaming might be better defined as matrix media, where content is made available away from the television set (Jenner 260). Regardless, the rise of streaming media platforms such as Netflix, Hulu, and Amazon Prime is commonly framed as part of televisual temporal disruption, as scholars note the growing plurality of televisual-type viewing options (Bury and Li 594). Further still, streaming platforms are often defined as television, a recent example occurring when Netflix CEO Reed Hastings called the service a “global Internet TV network” in 2016.The changing landscape of streaming and time-shifting notwithstanding, individuals remain aware of the viewing patterns of others, and this anticipation impacts the coordination and production of the collective television experience (Irani, Jeffries, and Knight 621). Related to this goal is how liveness connects viewers to shared social realities as they are occurring and helps to create a collective sense of time (Couldry 355-356). This shared experience of the social is still readily available in a time-shifted landscape, in that even shows released via an all-at-once format (for example, Netflix’s Stranger Things) can rapidly become a cultural phenomenon. Moreover, livestreaming has become commonplace as alternative to cable television for live events and sports, along with new uses for gaming and social media. As Graeme Turner notes, “if liveness includes a sense of the shrinking temporal gap between oneself and the rest of the world, as well as a palpable sense of immediacy, then this is something we can find as readily online as in television”. To this end, the claim that streaming media is harbinger of the “death of liveness” is far too simplistic. Liveness vis-à-vis streaming is not something that ceases to exist—shared temporal experiences simply occur in new forms.HQ TriviaOne such strategy to reactive a more traditional form of televisual liveness through streaming is to make streaming more social and mobile. Launched in August 2017, HQ Trivia (later retitled HQ Trivia and Words) requires users, known as HQties, to download the app and log in at 3.00 pm and 9.00 pm Eastern Standard Time to join a live gameshow. In each session, gameshow hosts ask a series of 12 single-elimination questions with three answer choices. Any users who successfully answer all 12 questions correctly split the prize pool for the show, which ranges from $250 to $250,000. Though these monetary prizes appear substantial, the per-person winnings paid out are often quite low based on the number winners splitting the pool. In the short time since its inception, HQ has had high and low audience participation numbers and has also spawned a myriad of imitators, including Facebook’s “Confetti” gameshow.Mobile streaming via trivia gameshows are a return to forms of televisual liveness and participation often disrupted by the flexible nature of streaming. HQ’s twice-a-day events require users to re-adapt to temporal constraints to play and participate. Just as intriguing is that “HQ sees its biggest user participation—and largest prizes—on Sundays, especially if games coincide with national events, such as holidays, sports games or award shows” (Alcantara). Though it is difficult to draw conclusions from this correlation, the fact that HQ garners more players and attention during events and holidays complicates notions of mobile trivia as a primary form of entertainment. It is possible, perhaps, that HQ is an evolution to the so-called second screen experience, in which a mobile device is used simultaneously with a television. As noted by Hye-Jin Lee and Mark Andrejevic, the rise of the second screen often enables real-time monitoring, customisation, and targeting that is envisioned by the promoters of the interactive commercial economy (41). Second screens are a way to reestablish live-viewing and, by extension, advertising through the importance of affective economies (46). Affect, or a preconscious structure of feeling, is critical to platform monetisation, in that the capture of big data requires an infrastructuralisation of desire—in streaming media often a desire for entertainment (Cockayne 6). Through affective capture, users become willing to repeat certain actions via love for and connection to a platform. Put another way, big data collection and processing is often the central monetisation strategy of platforms, but capturing this data requires first cultivating user attachment and repeat actions.To this end, many platforms operate by encouraging as much user engagement as possible. HQ certainly endeavors for strong affective investment by users (a video search for “HQ Trivia winner reactions” demonstrates the often-zealous nature of HQties, even when winning relatively low amounts of prize money). However, HQ departs from the typical platform streaming model in that engagement with the app is limited to two games per day. These comparatively diminutive temporal appointments have substantial implications for HQ’s strategies of valorisation, or the process of apprehending and making productive the user as laborer in new times and spaces (Franklin 13). Media theorists have long acknowledged the “work of watching” television, in which the televisual is “a real economic process, a value-creating process, and a metaphor, a reflection of value creation in the economy as a whole” (Jhally and Livant 125). Televisual monetisation is predominately based on the advertising model, which functions to accelerate the selling of commodities. This configuration of capital accumulation is enabled by a lineage of privatisation of broadcasting; television is heralded as a triumph of deregulation, but in practice is an oligopolistic, advertising-supported system of electronic media aided by government policies (Streeter 175). By contrast, streaming media accomplishes capitalistic accumulation through the collection, storage, and processing of big data via cloud infrastructure. Cloud infrastructure enables unprecedented storage and analytic capacity, and is heavily utilised in streaming media to compress and transmit data packets.Although the metaphor of the cloud situates user data as ephemeral and free, these infrastructures are better conceptualised as a “digital enclosure”, which invokes the importance of privatisation and commodification, as well as the materiality and spatiality of data collection (Andrejevic 297). As such, streaming monetisation is often achieved through the multitude of monetisation possibilities that occur through the collection of vast amounts of user data. Streaming and mobile streaming, then, are similar to the televisual in that these processes monetise the work of watching; yet, the ubiquitous data collection of streaming permits more efficient forms of computational commodification.Mobile streaming media continues the lineage of ubiquitous immaterial labor—a labor form that can, and commonly is, accomplished by “filling the cracks” of non-work time with content engagement and accompanying data collection. HQ Trivia, nevertheless, functions as a notable departure from this model in that company has made public claims that the platform will not utilise the myriad user identification and location data collected by the app. Instead, HQ has engaged in brand promotions that include Warner Brothers movies Ready Player One and Rampage, along with a brief Nike partnership (Feldman; Perry). Here, mobile and temporal valorisation occurs through monetisation strategies more akin to traditional televisual advertising than the techniques of big data collection often utilised by platforms. Whether or not eschewing the proclivity toward monetising user data for a more traditional form of brand promotion will yield rewards for HQ remains to be seen. Nonetheless, this return to more conventional televisual monetisation strategies sets HQ apart from many other applications that rely on data collection and subsequent sale of user data for targeted advertisements.Affective attachment and the transformation of leisure times through mobile devices is critical not just to value generation, but also to the relationship between mobile streaming and temporal and mobile control. As previously noted, Sharma elucidates that time is part of biopolitical forms of control, produced and experienced differently. Nick Couldry echoes these sentiments, in that there are rival forms of liveness stemming from a desire for connectivity, and that these “types of liveness are now pulling in different directions” (360). Despite common positionings, the relationship between television and streaming media is not a neat linear evolution—television, streaming, and mobile streaming continue to operate both side-by-side and in conjunction with one another. The experience of time, nevertheless, operates differently in these media forms. Explained by Wendy Chun, television structures temporality through steady streams of information, the condensation of time that demands response in crisis, and the most powerful moments of “touching the real” via catastrophe (74). New media differs by instead fostering crisis as the norm, in that “crises promise to move users from banal to the crucial by offering the experience of something like responsibility; something like the consequences and joys of ‘being in touch’” (Chun 75). New media crisis is often felt via reminders and other increasingly pervasive prompts that require an immediate user response. HQ differs from other forms of streaming and mobile streaming in that the plastic and flexible nature of viewing is replaced by mobile notifications and reminders that one must be ready for twice-daily games or risk losing a chance to win.In contributing to a sense of new media crisis, HQ fosters novel expectations for the mobile streaming subject. Through temporally-bound mobile livestreaming, “networked smart screens are the mechanism by which time and space will be both overcome and reanimated” as the “real world” is transformed into a magical landscape of mobile desire (Oswald and Packer 286). There is a double-edged element to this transformation, however, in that power of HQ Trivia is the ability to reanimate space through a promise that users are able to win substantial prize money only if one remembers to tune in at certain times. Within HQ Trivia, the much-emphasised temporal freedom of streaming time-shifting is eschewed for more traditional forms of televisual liveness; at the same time, smartphone technologies permit mobile on-the-go forms of engagement. Accordingly, a more traditional televisual simultaneity reemerges even as the spaces of streaming are untethered from the living room. It is in this reemphasis of liveness and sharedness that the user is simultaneously empowered vis-à-vis mobile devices and made mobile streaming subject through new temporal expectations and forms of monetisation.As mobile streaming becomes increasingly pervasive, new experimental applications jockey for user attention and time. HQ Trivia’s model of eschewing data collection for more traditional televisual monetisation represents attempts to recreate mobile media engagement not through individual isolated audio-visual practices, but instead through a live and mobile experience. Consequently, HQ Trivia and other temporally-bound gameshow apps demonstrate a reimagined live televisual experience, and, in turn, a monetisation of mobile engagement through affective investment.ReferencesAlcantara, Chris. “Diving into HQ Trivia: The Toughest Rounds, the Best Time to Play and How Some Users Beat the Odds.” The Washington Post 5 Mar. 2018. <http://www.washingtonpost.com/graphics/2018/business/hq-trivia/?utm_term=.02dc389ae3a9>.Andrejevic, Mark. “Surveillance in the Digital Enclosure.” The Communication Review 10.4 (2007): 295-317.Bury, Rhiannon, and Johnson Li. “Is It Live or Is It Timeshifted, Streamed or Downloaded?
