New Production Model Research Articles

Kill the Orchestra

In the age of participatory and convergence paradigms, video game music has its own networked culture with cybercommunities that discuss, share, and create content, thus opening up a creative space for artistic activities in a constant digital flow. Music composition and production is one of these activities, with files made available on several platforms such as SoundCloud and YouTube, specifically in the format of modification files (or mods). Building on research for a master’s dissertation, this article examines a new model of online artistic production in the form of the circulation of musical mods that were composed and shared on the Nexus Mods platform for the The Elder Scrolls IV: Oblivion and The Elder Scrolls V: Skyrim video games. These mods add new musical material that is similar to the existing soundtrack of both titles, but the majority of the files in this platform’s audio category are related only to sounds, not to musical composition. By using titles such as “better sounds” or “immersive sounds” to describe their additions, many modders aim to give other gamers a more immersive experience in the game(s). In this case, immersive relates not only to the musical style and sound quality of the aural effects but also a plausible construction of the reality in which the gamers live, play, and negotiate meaning relating to their own social context. Intersecting “playbour,” fandom, aural immersion, and audiovisual literacy, these audio modders work on adding new layers to the soundscapes and environments of the virtual worlds presented in the two games. The modders regard immersion as a key aspect of design and playability, and they contribute audio material to enable their social capital and visibility on online platforms.

Testing measurement model of consumption value in relation to consumers’ new electronics products adoption behavior in Ho Chi Minh City

The aim of this study is to examine the measurement model for new products’ consumption value and investigate the relationship between consumption value, adoption intention of new products and adoption behaviour of new products. Based on preceding theories, the consumption value concept is proposed as a multidimensional formative construct in this work. This study adopts partial least squares structural equation modeling (PLS-SEM) technique to test both the measurement model and hypotheses based on a data set of 915 consumers who bought and owned at least one new personal electronic device within 6 months before the survey was conducted in Ho Chi Minh city. The results show that the overall consumption value of new products is a second – order multidimensional formative construct with five first-order components which were also shown to have significant weights in the overall consumption value in the context of new personal electronic products, consisting of functional value, epistemic value, unique value, economical value and emotional value. The nomological validity is confirmed when the consumption value construct is shown to have a positive impact on both new products adoption intention and adoption behavior.

Entre la reiteración y la producción performática. Dos modelos de producción cultural para un nuevo giro performativo

En este artículo se analizan nuevos modelos de producción cultural relacionados con la adaptación de las artes vivas al museo. Centrándonos en el estudio de dos grandes exposiciones retrospectivas dedicadas al trabajo de Marina Abramović y de Tino Sehgal, tratamos de identificar el desarrollo de estrategias de reiteración performativa, mecanismos de exposición de archivos inmateriales, así como nuevos modelos productivos como son la producción de co-presencia y laproducción de intersubjetividad. Si en la segunda mitad del siglo XX el performance surgió como una herramienta subversiva con la que cuestionar el mercado y las instituciones culturales, la absorción y transformación de los performances en un nuevo producto de consumo cultural genera una serie de contradicciones, ya que la segunda oleada del performance —denominado como nuevo giro performativo— ha estado coordinada desde las mismas organizaciones museísticas que los artistas del performance trataron de cuestionar. Los contenedores expositivos se han convertido en puntos de encuentro entre obras vivientes y un público ávido de experiencias directas, donde creadores provenientes de otras disciplinas nutren y expanden los límites de las galerías, reemplazando con cuerpos vivos a los objetos artísticos. This article analyses new models of cultural production rooted in the adaptation of live arts within museum contexts. Focusing on the study of the great retrospective exhibitions of Marina Abramović and Tino Sehgal, we try to identify the development of performative reiteration strategies, exposure mechanisms of these immaterial archives, as well as new productive models such as the production of co-presence and the production of intersubjectivity. If in the second half of the 20th century, performance emerged as a subversive tool through which to question the market and cultural institutions, the absorption and transformation of performances into a new product of cultural consumption generates a series of contradictions affecting its essence, especially since this second performance wave —named as a new performative turn— is driven by the same museums and cultural institutions that performance artist once tried to question. The exhibition containers have become meeting points between artists and an audience eager for direct experiences, where creators from other disciplines nurture and expand the galleries boundaries, replacing artefacts for living bodies.

Direct transgene expression and mAb production by using new model UCOEs on iPS and CHO cells

Background & Aim It has recently been shown that efficient and stable expression of transgenes from the A2UCOE is at least in part due to its resistance to DNA methylation- mediated silencing. Analysis of a deletion series from the CBX3 end of a fully functional 2.5kb A2UCOE where expression of an eGFP reporter gene is directly driven off the HNRPA2B1 promoter, revealed a 1.2kb and 1.7kb truncation that retained full UCOE activity following transduction of P19 and F9 cells in both undifferentiated and differentiated states. These 1.2-1.7 and a further deletion 0.5kb A2UCOEs, were also able to retain stable expression in murine embryonic stem cells and now in human iPS cells during differentiation into embryoid bodies and three different tissue specific cell types. In addition, from a practical perspective our finding that the 0.5-1.2-1.7A2UCOEs retain the same stability of expression as the larger 2.5kb A2UCOE model suggests that it can effectively replace the latter within therapeutic LV constructs allowing a greater capacity and also more safety for the gene of interest by cutting off the enhancer elements which carries a potential mutation risk. A further project now on human mAb production with recombinant CHO cells by using our new UCOE models has been started and the early results show that they are more productive than the control A2UCOEs and able to produce human recombinant mAbs in mg to g level even under two months of cultivation. The results already encouraging to provide a new better UCOE model for recombinant protein production in mammalian cells. Methods, Results & Conclusion Firstly, the new UCOE models were cloned into lentiviral vectors and then the vectors were produced by 293T cells. Then, human iPS cells were transfected by the vectors without differentiation. The expression of the UCOE models were observed over 42 days by measuring eGfP+ cell levels in flow cytometry every week. The experiments then were followed by differentiation of transduced iPS cells into three different tissue spesific cell types (pre and neuronal, hepatocyte and cardiomyocyte cell types). Secondly, the aimed mAb DNA sequences were produced by PCR, and clonned into our UCOE vectors and then they were transduced into the CHO group sub-cell clones which the recombinant protein production will be done and the mAbs will then be isolated from the cell culture and analysed by correction methods. After the correction analyses, the production of aimed IgG1 ve IgE/k group mAbs were produced in bioreactor in gram level.

The Linguistic Perspectives on Computer Mediated Communication

This paper aims to explore the role of production and perception constraints in computer mediated communication. I review Lindblom's (1990) theory of phonetic variation and propose a new model of linguistic production in Computer Mediated Communication. Cyber citizens use cyber communication as conceptually oral, medially written. The reason to use chat-mode is that it saves time and space (the principle of least effort); here sound, not spelling, is the first thing to be considered. With respect to production in the proposed model, effort is no longer equated with articulatory movement, but rather with the number of keystrokes involved in typing an utterance. On discussing online, discussants show paralinguistic actions such as smile, frown, screaming, etc., and they also reduplicate writings, capitalize all the sentences, and use emoticons; net-communication is headed toward less grammatical and more telegraphic type. The production of hyper-and hypo-forms such as reduplication, punctuation and capitalization will vary according to the sender's estimation of signal-complementary processes and his attempts to compensate for the restricted context.We discuss online and off line on the issues; why we like cyber communication and how we classify the phenomena. The more computer mediated communications we use, the moreissues we have to review beyond words and linguistic principles.

The sustainable manufacturing concept, evolution and opportunities within Industry 4.0: A literature review

Today’s society is becoming aware that a new economic model of production and consumption must take into account its environmental and social impact. Industries are under increasing pressure from stakeholders to be transparent in reporting the environmental and social impacts of their operations. In this context, sustainable manufacturing must minimize negative environmental impacts and consumption of energy and natural resources, while also being socially responsible and economically viable. That is why the sustainable manufacturing concept is gaining increasing attention both in the research community and in organizations, especially in the industrial sector. However, even today, there is a great diversity of interpretations and ideas associated with this term. Accordingly, this article first presents an overview of the main concepts related to sustainable manufacturing, and metrics to evaluate organizations’ sustainability performance, and then an outlook of current trends. Our work highlights the consistencies and inconsistencies in the research community related to the interpretations of sustainable manufacturing and Industry 4.0, as well as the lack of consensus about the true social impact of Industry 4.0. However, the positive ecological and economic impacts of sustainable manufacturing seem fairly widespread. In this way, sustainable manufacturing practices seem to be reinforced by initiatives within the fourth stage of industrialization – the so-called Industry 4.0 – which offers great opportunities for sustainable manufacturing, thanks to digital transformation.

A game theoretic approach for the duopoly pricing of energy-efficient appliances regarding innovation protection and social welfare

Recent developments in energy consumption ‘management’ have heightened the need for energy efficiency considerations in energy-intensive supply chains, according to the sustainable development framework. Therefore, policy-makers need to find out how they can improve these conditions, considering the resource limitations and energy requirements. According to these issues, we address a novel pricing model for new energy-efficient products, conventional models, and relative energy consumption under a tax-subsidy system. The products and energy services are made in a product supply chain consisting of an energy supplier and two manufacturers in a duopoly. Furthermore, the protection costs of innovation process such as copyright are investigated for the first time in this problem. Then, a multi-stage game model is developed considering two scenarios, based on different game structures. Finally, we solve the problem and provide a comprehensive analysis of the optimal values of variables and players’ profit. The results show that the first scenario has more advantages than the leader-follower competition. However, the second scenario results in less energy consumption than the first one. The findings also suggest that energy policies applied on the producer side are more effective than the consumer-side energy policies to improve energy-saving.

Development and validation of a scale for identification of quality attributes of agri-food products in short chains

The quality of the agri-food product, as well as the attributes that define it, has been developed for decades, where discussions around the theme turned to questions related to the standardization of attributes. It should be noted that the theoretical lines associated with the theme are derived from production systems models where production productivity and distribution on a global scale are the guiding principles of food production. Currently, there is greater demand for products coming from a model that contrasts with the global-scale production model, which emphasizes the aspects of standardization of products and processes. This new model of food consumption highlights specific characteristics of product quality related to the location and proximity to the producer. Discussions about product quality in this new model of production and consumption (agri-food short chains) are recent and need a theoretical and practical deepening, in view of the new demands of consumers for these products. This paper aims to present the development and validation of a scale with quality attributes from the consumer point of view applied specifically to food and beverage products characterized by agri-food short chains. Items were generated (27 quality attributes) from an extensive theoretical review (quality conventions), subjected to face validation, and then used to collect data from 904 consumers in short food distribution channels in the Brazilian state of São Paulo. The data were analyzed through exploratory and confirmatory factor analysis, which resulted in a final scale composed of 20 quality attributes comprising, domestic, civic, regard, institutional, and market conventions.

A new mathematical model for production and delivery scheduling problem with common cycle in a supply chain with open-shop system

A new mathematical model for production and delivery scheduling problem with common cycle in a supply chain with open-shop system

A new mathematical model for production and delivery scheduling problem with common cycle in a supply chain with open-shop system

In order to coordinate the supply chain, reordering strategy of needed goods must be synchronised and sequence of production and replenishment cycle time must be optimised in terms of cost. Therefore, this paper studies the economic lot and delivery scheduling problem for multi-stage supply chain. The common cycle time and integer multiplier policies were adopted to accomplish the desired synchronisation. In this regard, a new mathematical model has been presented where a manufacturer with open-shop system purchases raw materials from suppliers and sends them to packaging companies after converting them into the final product and then they are sold. Since this is a non-deterministic polynomial-time hard (NP-hard) problem, simulated annealing algorithms have been developed for it. For this algorithm, two different scenarios have been proposed for solving the study problem and at the end the numerical results have been applied on problems with different dimensions by the algorithm.

Probabilistic reference model for hourly PV power generation forecasting

This paper presents a new probabilistic forecasting model of the hourly mean power production in a Photovoltaic (PV) plant. It uses the minimal information and it can provide probabilistic forecasts in the form of quantiles for the desired horizon, which ranges from the next hours to any day in the future. The proposed model only needs a time series of hourly mean power production in the PV plant, and it is intended to fill a gap in international literature where hardly any model has been proposed as a reference for comparison or benchmarking purposes with other probabilistic forecasting models. The performance of the proposed forecasting model is tested, in a case study, with the time series of hourly mean power production in a PV plant with 1.9 MW capacity. The results show an improvement with respect to the reference probabilistic PV power forecasting models reported in the literature.

Phyto-VFP: a new bio-optical model of pelagic primary production based on variable fluorescence measures

Abstract Marine primary production (PP) is a key factor in the regulation of the global carbon cycle, with important potential feedback on climate. Seventy percent of marine PP is generated by phytoplankton photosynthesis. However, the phytoplankton productivity rate is dependent on the photo-physiological state of phytoplankton cells, as well as other environmental conditions. To consider these variables appropriately, refine the current estimates of PP, and reduce the laboursome and lengthy methodologies of radiocarbon estimates, we have created “Phyto-VFP” (Variable Fluorescence Phytoplankton Production), a new bio-optical model classified as a Wavelength and Depth-resolved (WDR) model. The model integrates the effect of the photo-acclimation processes on the “active” fraction of the phytoplankton population with the dynamic of the water column, parametrised through a series of laboratory experiments based on in vivo variable fluorescence measures on the marine diatom Skeletonema costatum (Greville) Cleve. The performance of Phyto-VFP was compared with concurrent estimates of radiocarbon (14C) uptakes, under different dynamic and optical conditions, during two oceanographic cruises (SAMCA3 and SAMCA4) in the Mediterranean Sea. The low Root Mean Square Differences (RMSDs) show that Phyto-VFP performs well when estimating phytoplankton PP. When compared to other bio-optical models, Phyto-VFP estimates of PP in coastal waters were closer to radiocarbon measurements than other models could predict [e.g., the Morel model (MM)]. The application of Phyto-VFP to the SAMCA dataset and its comparison to MM allowed the assessment of model performance under three different physical and biological conditions, in which it was possible to analyse how photo-physiological responses of phytoplankton influence PP.

A new model for study of quality attributes to components based development approach

Software development costs, time-to release and quality product are important factors affecting the construction of software. Different types of tools and techniques are suggested by researchers to improve in delivering quality software systems with lower cost and reduce time to delivery. One such practice is development of software using Component Based Software Development (CBSD) techniques[1]. CBSD recommended building software systems using existing reusable components, instead of writing from scratch. The main objective of CBSD is to writes once and reuse any number of time with no or modification. Some of the advantages that a company may available by adapting CBSD for the Software development are shorter development time which results in meet tight dead line, increase productivity and Quality Product. CBSD also, support reusability[3]. The aim of this paper is to develop the new model of software product and describe the characteristics of some selected of attributes of CBSD models that are widely practiced in software industries with explain about IT project. We proposed a complete model for Component Based Software Development for reuse. This Model will cover both component based software development as well as Component development phases for A-Model. This Model is represent one good solution for Component Based Development with reduce cost and time to deliverable and save the quality of product

Dropout prevention in Secondary VET from different learning spaces: A social discussion experience

Context: In 2016, the early leaving from education and training (ELET) rate in the Balearic Islands, Spain, was 26.8%. According to the most recent data, the participation rate in intermediate vocational education and training (VET) was 31.5%, and the graduation rate was 53.2%. In this paper, we present the main elements of the social agreement among political and social actors, derived from social discussion, which may form the main building blocks for addressing the problems of ELET and, more specifically, dropout in VET. Approach: The social discussion was developed under the need for a broader and more inclusive vision between the formal education system and the community as well as among their agents and initiatives, the mutual understanding between the educational strategies and the models of formal and non-formal education systems and the need for a dynamic and holistic approach to experiential learning processes. As researchers, we analysed the video-recorded content of participants’ contributions using three categories: problems, strategies for improvements and contributions of the work group to the social agreement.Findings: The experience evidenced the severity of the ELET problem in the Balearic Islands and proved that preventing ELET and returning people between the ages of 16 and 24 to education and training programmes must become political priorities. The social agreement reflects the consensus reached regarding the need to work in networks, encourage collaboration between formal and non-formal education and emphasise the central role of the community and the active participation of students. The proposed actions regarding VET focus on the need to establish a system that integrates VET from education and from employment systems and the need to increase the offer to connect with the needs of businesses, the territory and a new model of production. The necessity of improving the quality of the system, moving towards more inclusive education and training teachers to recognize and reduce dropout risk factors was also brought up. Conclusion: The social agreement is possible even in contexts with little tradition. The innovation of this experience lies in its equating all participants at the same level of discussion. We highlight the intersection of the variety of positions that emerged in the debates as well as the consensus reached regarding the suggested proposals to address the problem of ELET and dropout in VET in the Balearic Islands.

Pricing decision model for new and remanufactured short life-cycle products with green consumers

Remanufacturing has been studied quite extensively during the last decades, as one of product recovery options that could extend product’s useful life and mitigate the environmental impact. Rapid innovation in technology accelerates obsolescence and hence product life cycles are getting shorter and wastes build up faster. Remanufacturing of short life-cycle product is an important alternative to mitigate the waste. However, since there are impacts in implementing remanufacturing, such as cannibalization, segmentation, and lower willingness to pay, pricing has become a significant aspect to ensure successful remanufacturing business. Several studies show that there exists green segment consumer, who has higher preference to purchase environmental-friendly products and higher willingness to pay for such products. In this paper, we study manufacturer’s and retailer’s pricing decision of short life-cycle product considering the green segment consumers, and propose two scenarios i.e. independently optimized profit scenario under Stackelberg game with manufacturer as the leader, and integrated scenario. The results show that the integrated scenario achieves higher profit compared to the independent one, and both players are better off under the integrated decision. We also find that the existence of green segment increases the profit of manufacturer and retailer to a certain level, before it erodes manufacturer’s profit when the green level is too high. In addition, price sensitivity of new and remanufactured products, demand’s speed of change, and remanufacturing cost influence the optimum prices as well as the optimum green level. For firms that are engaging in remanufacturing, managerial insights are also provided to assist managers in making pricing decisions when there exist green consumers.

Variations in continental heat production from 4 Ga to the present: Evidence from geochemical data

Crustal heat production accounts for 30 to 40% of continental heat loss and enhances thermally controlled processes such as melting and metamorphism, yet is in general poorly constrained. We present a new model for continental igneous heat production from ∼4 Ga to the present using a global geochemical database of 75,800 whole-rock analyses providing the highest resolution record to date. Hypotheses advanced to explain past heat production–age variations include erosion of the enriched felsic upper crust, decay of the radioactive elements, geodynamic processes such as the supercontinent cycle, secular cooling, lithological controls, and/or a major shift in the bulk composition in the crust during the late Archean. However, previous heat production–age models are often coarsely resolved, poorly sampled, and/or spatially biased. To test these hypotheses and refine secular trends in crustal heat production, we construct a model by correcting for radioactive decay and normalizing by SiO2 content to remove the gross influence of lithology. The variations through time are highly correlated among both plutonic and volcanic samples, as well as mafic and felsic distributions. Unsurprisingly, compositional normalization indicates lithological control is the dominant factor on heat production after the influence of decay is removed. Following these adjustments, we find that heat production has been relatively constant through time. We suggest the heat production–age pattern does not significantly reflect the influences of erosion, secular cooling, depletion, or the supercontinent cycle as suggested by some previous studies. Heat producing element distributions might be expected to be similar regardless of the age of melt generation, once compositionally normalized and adjusted for the decay of the various isotopes. Compared to this reference model, we observe a heat production and heat producing element enrichment deficit, particularly for the Archean and Paleoproterozoic. This deficit is accounted for by a rapid increase in heat producing element concentrations associated with a shift in the bulk composition of the crust from the early Archean to ∼2.7 Ga. Additionally, we suggest that the heat production record may also represent a biased sample set, perhaps as a result of selective preservation due to thermal stability. This new model will lead to better crustal heat production and global heat loss estimates both at present and within Earth's past.

Applying a fuzzy multi-objective model for a production–distribution network design problem by using a novel self-adoptive evolutionary algorithm

In this paper, a new fuzzy bi-objective mathematical model for production–distribution problem under uncertainty for a four-echelon supply chain network design involving of several suppliers, producers, distributors, customers, and a set of transportation modals with different reliability rates are presented. In addition to minimise the total cost of the supply chain, the second objective is maximising reliability rate of the whole proposed system. In order to solve the proposed model, a hybrid two-phase solution procedure is proposed based on possibilistic programming, fuzzy multi-objective programming and an efficient algorithm called self-adaptive differential evolution algorithm. Finally, an extensive comparison by a set of numerical examples with different complexity along with some sensitivity analyses has been reported to explore the efficiency of proposed model as well as the performance of proposed evolutionary algorithm.

The Use of Fragmented, Worn-Out Car Side Windows as an Aggregate for Cementitious Composites.

The paper describes a new model of concrete production, which contains a glass cullet. A worn-out car side window have been used for the production of recycled glass aggregate (RGA) and its properties were examined. The RGA was used in concrete as a 50% and 100% mass substitute of the traditional aggregate. Basic tests of fresh concrete mix and hardened concrete were carried out. The consistency, the air content in the concrete mix, the density of hardened concrete, water absorption, water resistance, frost resistance, and the compressive strength (after 9, 28, and 90 days) were evaluated. Composite samples were also subjected to microscopic analysis. The results showed that the RGA can be recommended as an aggregate for concretes, and the features of the RGA concrete are more favorable than those of traditional concrete. The microscopic analyses allowed us to identify the reasons for improving the properties of the RGA composites.

Optimization of EOQ Model for New Products Under Multi-Stage Adoption Process

The available literature on new product sales growth models mostly ignores two important aspects of technology diffusion: diffusion of awareness and the actual adoption. This characteristic of technology adoption is extremely important from inventory management perspective as buying decision is often influenced due to time lag between information propagation and actual adoptions. As high-technology market is extremely unpredictable, interactions between technological evolutions and customer feedback effects play an important role in technology diffusion. The demand models mostly considered in inventory literature to develop economic order quantity (EOQ) model ignore this important element of technology diffusion. In this paper, we proposed an EOQ model for high-technology products by incorporating customer feedback effects along with market heterogeneity to optimize the total inventory cost. The demand model considered in the paper follows lifecycle phenomenon and is sensitive to unit selling price. To remove any ambiguity pertaining to costs, fuzzy nature of ordering and inventory carrying cost is considered in the paper.

New SAGD model for oil production using a concave parabola steam chamber geometry

In this paper, a new steam chamber growth model using a concave parabola interface is presented. Steam chamber shape is crucial in describing the expansion of injected steam and the propagation pattern of the temperature of the steam front towards the producing well. Steam chamber evolution is particularly important for predicting oil production during steam assisted gravity drainage (SAGD) processes.The new model is derived based on the orientation of the temperature isoline obtained for the underground test facility (UTF) project, the results of several experiments, and the numerical simulation of SAGD processes for major field projects. The analytical description of this steam chamber growth pattern will assist in evaluating and developing fields using SAGD scheme. The model employs the concept of heat conduction involving a moving solid to estimate the steam chamber interface temperature profile and, eventually, the oil production rate and associated steam injection rate required based on an energy balance approach. This study builds upon the assumptions of Butler and Reis’ linear interface by introducing a parabolic steam interface. It is demonstrated that the new model predicts oil production and steam injection rates with higher accuracy than existing models. It also showed the strong variation of oil rate with time unlike the constant rate assumption. The results of the model are compared with the experimental data from Cheng and Butler, simulation with a CMG STARS simulator and the results of the UTF phase B project, which show better agreement and robustness.
