Study of the bread baking process - II. Mathematical modelling
No full textA mathematical model of baking was set up and validated experimentally. The model describes heat and mass transport phenomena during baking of a cylindrical bread sample. The model was solved by finite difference numerical method. The model is based on the hypothesis described in a previous work (Zanoni, B., Peri, C. & Pierucci, S. (1993). J. Food Eng., 19, 383-98), that the variation in temperature and moisture of bread during baking is determined by the formation of an evaporation front at 100°C. The progressive advancing of the evaporation front towards the inside of the product determines different conditions of heat and mass transport in a crust and crumb portion. The validation shows that the model correctly simulates heat and mass transfer during baking. © 1994
Templates of Ethnographic Writing in Organization Studies: Beyond the Hegemony of the Detective Story
No full textUsing a translation lens, we explore templates for writing ethnography in organization studies and their
evolution over time through the analysis of all ethnographic papers published in the premier journal
Administrative Science Quarterly, 1956-2018.We found three templates of ethnographic writing. Few early
ethnographic papers resemble travelogues, as they use theory to explain a unique case based on firsthand
experiences of the author. Most studies read like detective stories, using extensive, quantified data from a
case and systematically analyzing it to advance theory. This template has remained predominant over time.
Finally, some ethnographic papers read like postmodern detective stories, in that they attempt to create
knowledge from lived experience, while also hinting at the partiality of this knowledge. This template
appeared around the turn of the century but is today rare. The overall low number of ethnographies and
the lasting hegemony of the ethnography as detective story template reflect the strict disciplining of
ethnography into the emulation of positivist research, constraining knowledge creation in organization
studies. We conclude by offering researchers some strategies to recover the strengths of templates
available in the past to broaden the boundaries of existing norms for writing ethnography today.We thank Tamar Gross and Merav Migdal-Picker for their help in the research process.

Post-Diversity, Precarious Work for All: Unmaking borders to govern labour in the Amazon warehouse
No full textThis paper investigates the (un)making of borders as a form of labour governmentality in one of Amazon's warehouses in Poland. Guided by a critical theory of borders as a form of labour governmentality under global capitalism, we identify organizational practices through which socio-demographic categories traditionally deployed as principles of organizing work (e.g., gender, age, ability) are unmade: the management of deskilled labour through an algorithmic system, the non-selective hiring of workers, the enforcement of social norms of interpersonal respect and a universal system of casualized employment. Together, these practices constitute workers as undifferentiated, interchangeable and equal labour, let them compete with each other under harshly exploitative conditions, and continuously dispose of the least productive among them, keeping all in structural uncertainty. The study contributes to the critical diversity literature by showing a 'post-diversity' governmentality that rests on equality, competition and precarization of labour as a whole, rather than segregation and marginalization through an 'ideal worker' norm. This labour governmentality operates by eliciting consent from historically subordinated workers and eliminating the advantage of historically relatively privileged ones. Unmaking borders within labour inside the organization, this governmentality at the same time crucially rests on borders outside it.The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: We would like to acknowledge the funding Patrizia Zanoni received from the Flemish

No full textCoercion and Consent under Techno-Economic Despotism: Workers' Alienation and 'Liberation' in the Amazon Warehouse
No full textThis article explores the role of subjectivity in workers' control in warehouses. Relying on Marx's theory of the alienated subject under capitalism, we analyse the narratives of Polish Amazon workers to understand how alienating work produces a contradictory consenting subject. Workers are both estranged from the labour process, commodities, social relations and themselves, and simultaneously reconstituted as agents with new potentialities. Reflecting Marx's 'civilising' dimension of capitalism, they are reconstituted as sellers of labour, consumers, individuals deserving respect and holders of legal rights. This transformation elicits workers' consent to alienating work conditions because these new possibilities depend on such conditions. Our study advances discussions of control in global warehousing by highlighting how workers' consent operates alongside coercion. It also advances our understanding of consent by showing that it is not merely a coping mechanism for meaningless work but rather emerges from workers' integration into capitalist relations.Funding

Technical note on “Inventory management in supply chains with consideration of Logistics, green investment and different carbon emissions policies”
No full textThis study presents an extension of the model proposed by Huang et al. (2020), which investigated the effects of carbon policies and green technologies on the integrated inventory management of a two-echelon supply chain with consideration of carbon emissions during the processes of production, transportation, and storage. Specifically, since the inventory policy impacts on the economic and environmental performances of the supply chain, this study proposes a mathematical model for the integrated inventory management of the single-vendor single-buyer supply chain under a consignment stock policy. The aim is, thus, to highlight advantages and disadvantages of the consignment stock agreement with respect to the traditional policy based on the model proposed by Hill (1999). To compare the results, the same three carbon emissions policies are considered: i.e., limited total carbon emissions, carbon taxation, and cap-and-trade. The proposed model can assist firms in determining their optimal inventory policy (i.e., agreement, production quantity, delivery quantity, and green investment amount) with an aim of minimizing the supply chain costs under different carbon emissions policies
Coffee ultrafiltration: composition and shelf-life of the permeate
No full textIn this paper, sensory and physio-chemical characteristics of a coffee brew and permeate obtained under iner gas ultrafiltration are described and compared. The coffee permeate, compared to the coffee brew, show a decrease in dry extract content, absence of lipids, a much highter colour and a slight difference in aromas. The coffee permeate is sensorily less bitter and has less richness of flavour than the coffee brew. During shelf-life, the permeate colour is similar to that of the coffee brew. Moreover, sensory evaluation shows that the permeate is much more stable than the coffee brew (weeks for the permeate compared to days for the coffee brew)

Rate of carotenoid degradation in dehydrated carrots
No full textThis work was focused on dehydrated carrots with the aim to study: a) the water sorption properties, and b) the rate of carotenoid degradation as a function of water activity. Freeze-dried carrots from blanched and not blanched batches were placed in air-tight glass jars containing saturated salt solutions with water activity ranging from 0.052 to 0.75, at 40°C. The equilibrium moisture, water activity, and carotenoid content were analysed at different storage times. Results showed that the adsorption isotherm fitted the Guggenheim-Anderson-de-Boer (GAB) equation (R2 = 99.65%). Estimated monolayer water activity was 0.33 (confidential limits at 95%: 0.26 and 0.38). α- and β-Carotene contents decreased in all dehydrated carrots following pseudo-first-order kinetics, with rate constants ranging from 0.031 to 0.374 days-1. Similar rate constants were found between α- and β-carotene. In all carrot batches the rate of carotenoid degradation was at a minimum within the water activity range 0.31 - 0.54. Below and above this range the rate of carotenoid degradation increased significantly. Blanching resulted in a higher initial carotenoid content, but it accelerated carotenoid decrease during storage of dehydrated carrots. Based on these results we concluded that two strategies could be useful to increase carotenoid stability during storage: a) the development of intermediate moisture carrots (water activity in the range 0.31 - 0.54); b) the identification of protective factors that can increase carotenoid stability at water activity above 0.54. Both criteria should be combined with optimised packaging conditions, which reduce exposure of product to air and light during storage
