Résumé :

A methodology was developed to incorporate the structural contribution of working platforms, including those constructed with industrial byproducts, into the design of flexible pavements. Structural contribution of the working platform was quantified with the 1993 AASHTO flexible pavement design guide in terms of a structural number or an effective roadbed modulus. Two methods are proposed. One method treats the working platform as a subbase layer and assigns a structural number to the working platform for use in computing the overall structural number of the pavement. The other method adjusts the effective roadbed modulus to account for the improvement in the roadbed provided by the working platform. Resilient modulus obtained from large-scale model experiments conducted on several working platform materials (e.g., breaker run stone, Grade 2 gravel, foundry slag, foundry sand, and bottom ash) was used in the analysis. Design charts show the structural number or the roadbed modulus as a function of type of material and thickness of the working platform.

Résumé :

The growing application of smart manufacturing systems and the expansion of the Industry 4.0 model have created a need for new teaching platforms for education, rapid application development, and testing. This research addresses this need with a proposal for a model of working environment monitoring in smart manufacturing, based on emerging wireless sensor technologies and the message queuing telemetry transport (MQTT) protocol. In accordance with the proposed model, a testing platform was developed. The testing platform was built on open-source hardware and software components. The testing platform was used for the validation of the model within the presented experimental environment. The results showed that the proposed model could be developed by mainly using open-source components, which can then be used to simulate different scenarios, applications, and target systems. Furthermore, the presented stable and functional platform proved to be applicable in the process of rapid prototyping, and software development for the targeted systems, as well as for student teaching as part of the engineering education process.

Résumé :

In this contribution to the Media-N special issue, “Humans Are Underrated: Art & Labor in the Amazon Economy,” I narrate creative projects that disrupt or interfere with the Mechanical Turk platform. My place as an artist and employer in the elastic workforce since 2008 has given me a close and nuanced view of life online in the virtual workplace. The jobs I have created on the platform ask workers to perform athletic events, create videos, meditate, and talk back to Jeff Bezos. The materials I collect from the workers are integrated into art works that amplify the visibility of the workers and their unique voices. This article shows how those “underrated” humans in the Amazon economy are creative, thoughtful, and intelligent.

Résumé :

A study was conducted in the field and with a large-scale model experiment (LSME) to evaluate the structural contribution of a 0.30-m-thick geosynthetic-reinforced granular layer used as a working platform for construction over soft subgrade. The study was conducted in the context of the 1993 AASHTO design guideline, in which the structural number (SN) of the pavement is based on layer coefficients (each defined using a resilient modulus). Working platforms reinforced with geosynthetics had smaller elastic deflections and larger elastic moduli than unreinforced working platforms with the same thickness. Reinforcement factors obtained in the field ranged from 1.2 to 1.8; those obtained in the laboratory ranged from 1.7 to 2.0, with greater reinforcement factors for the less extensible geosynthetics (geogrid, woven geotextile) for a 0.3-m-thick granular working platform. Of the four geosynthetics tested, the geogrid resulted in the greatest increase in modulus. Reinforcing the working platforms with geosynthetics resulted in increases in layer coefficients ranging from 50% to 70%. Similarly, increases in SN for a typical pavement structure were realized, ranging from 3% to 11% when all other factors were equal.

Résumé :

Urban planners are increasingly working with ideas around datafied cities, such as platform urbanism, to understand urban life and changes with technology. This article seeks to assist urban planners in these efforts by analysing and mapping the qualities of platform urbanism. Drawing on a dataset of approximately 100 examples that detail urban data practices, we trace some of the current tendencies that are shaping the nature and dynamics of platform urbanism. While we identify no unifying narrative or overarching pattern to our data, we interpret this as supporting Barns’ (2019) notion of a pivot towards platforms. We argue this through exploring the interoperability between data sources and domains (vertical and horizontal integration), identifying elements of how platforms intermediate urban life through their growth in different sectors and the use of geolocation, and note the different artefacts that contribute to platform urbanism. We also note a concerning dynamic where city administration becomes ‘locked in’ to specific corporate products and interests, and thereby ‘locked out’ from alternatives. We discuss this in the context of social inclusion and what this means for urban planners, including the fragility of corporate platforms and what platforms urbanism means for social relationships in the city.

Résumé :

The paper deals with a dynamic analysis of a passive suspension of a working machine horizontal platform and the two configurations of its suspension system. For the individual alternatives the mathematical models are formulated. The rigid horizontal platform is excited in two perpendicular horizontal directions by kinematic excitation, which was acquired by an experimental measurement of the displacements of the working machine cabin. For the arbitration of which configuration is better two criterions were considered. The first criterion was the effective displacement in two perpendicular directions of the suspended horizontal plate and its rotation around the vertical axis. The second criterion was the effective acceleration of the horizontal plate in two perpendicular directions and the angular acceleration around the vertical axis. The numerical simulations shown that the first alternative (marked as A) gives better results in the reduction of vibration.

Résumé :

Building on an emerging literature concerning algorithmic management, this article analyzes the processes by which food delivery platforms control workers and uncovers variation in the extent to which such platforms constrain the freedoms—over schedules and activities—associated with gig work. Drawing on in-depth interviews with 55 respondents working on food delivery platforms, as well as a survey of 955 platform food delivery workers, we find that although all of the food delivery platforms use algorithmic management to assign and evaluate work, there is significant cross-platform variation. Instacart, the largest grocery delivery platform, exerts a type of control we call “algorithmic despotism,” regulating the time and activities of workers more stringently than other platform delivery companies. We conclude with a discussion of the implications of the spectrum of algorithmic control for the future of work.

Résumé :

This paper presents our work in the design and development of collaborative platforms to support distributed scientific collaborations in a national biosecurity laboratory which carries out diagnostics and research work in animal diseases. We have focused on two types of collaboration challenges. One is the “distributed” collaborations between scientists working inside the physical containment areas and scientists working in the general office area within the laboratory. The second is the collaborative diagnosis and decision-making work between this laboratory and other organizations working on the responses of emergency animal diseases. The “biosecurity collaboration platform” which addresses the first challenge has been implemented and used by the scientists in the laboratory. The platform integrates shared digital workspaces and supports the sharing and interaction of scientific data from various resources and laboratory instruments (e.g. microscopes). The “secure collaboration platform” which addresses the second challenge is an extension of the biosecurity collaboration platform and integrates eAuthentication and eAuthorization technologies to support secure communication and information sharing between experts from different organizations. Results from user studies have shown that the collaboration platforms can provide core capabilities of communication, trustworthy information sharing and access to real-time data from scientific instruments in complex collaborations in the biosecurity domain.

Résumé :

AbstractThe Fairwork Project is an international action-research project that currently operates in over 20 countries. The project focuses on working conditions in the platform economy, in order to develop ‘fairness ratings’ for digital labour platforms. With respect to Germany, the project evaluated the working conditions offered by ten digital labour platforms, by scoring them against the Fairwork principles and producing a national league table. We found that even in a highly regulated labour market context like the German one, platform workers experience precarity and insecurity and have limited access to employment rights. A number of platform workers are classified as employees rather than self-employed, and this guarantees a number of employment rights, including entitlement to minimum wage, health and safety protection and social protection. However, the existence of an employment relationship does not necessarily ensure platform work to be fair as other factors, including the existence of complex networks of subcontracting, erode labour standards and deprive workers of basic employment rights.Practical Relevance: While there are tens of millions of digital platform workers around the world performing functions essential to society—as demonstrated drastically by the Covid-19 pandemic—by supplying food, care and passenger transportation services, many platform workers face low pay, precarity as well as poor and dangerous working conditions. Exposing fracture lines of inequalities affecting particularly women, migrants and minority-ethnic groups who form the core part of the gig workforce, the international Fairwork research project aims not just to understand the gig economy, but to change it.

Résumé :

Research has shown the multitude of applications that Internet of Things (IoT), cloud computing, and forecast technologies present in every sector. In agriculture, one application is the monitoring of factors that influence crop development to assist in making crop management decisions. Research on the application of such technologies in agriculture has been mainly conducted at small experimental sites or under controlled conditions. This research has provided relevant insights and guidelines for the use of different types of sensors, application of a multitude of algorithms to forecast relevant parameters as well as architectural approaches of IoT platforms. However, research on the implementation of IoT platforms at the commercial scale is needed to identify platform requirements to properly function under such conditions. This article evaluates an IoT platform (IRRISENS) based on fully replicable microservices used to sense soil, crop, and atmosphere parameters, interact with third-party cloud services for scheduling irrigation and, potentially, control irrigation automatically. The proposed IoT platform was evaluated during one growing season at four commercial-scale farms on two broadacre irrigated crops with very different water management requirements (rice and cotton). Five main requirements for IoT platforms to be used in agriculture at commercial scale were identified from implementing IRRISENS as an irrigation support tool for rice and cotton production: scalability, flexibility, heterogeneity, robustness to failure, and security. The platform addressed all these requirements. The results showed that the microservice-based approach used is robust against both intermittent and critical failures in the field that could occur in any of the monitored sites. Further, processing or storage overload caused by datalogger malfunctioning or other reasons at one farm did not affect the platform’s performance. The platform was able to deal with different types of data heterogeneity. Since there are no shared microservices among farms, the IoT platform proposed here also provides data isolation, maintaining data confidentiality for each user, which is relevant in a commercial farm scenario.

Résumé :

Working capability analysis of planar and spatial Stewart platforms with unilateral constraints on actuator length is carried out using numerical methods based on analytical criteria for the boundary of the accessible output set. Restrictions on achievable motion at singular configurations associated with points interior to the accessible output set are also analyzed. Since movement of the working point on a spatial Stewart platform occurs in three-dimensional space, the boundary of the accessible output set is a two-dimensional surface. Numerical methods used in this analysis map one-dimensional solution sets, permitting the boundary of the accessible output set to be characterized by a family of one dimensional generators. Motion control restrictions inside the accessible output set are similarly characterized by families of interior singular curves, and barriers to motion control across surfaces defined are analyzed.

Résumé :

Background: Loss of balance is a considerable risk factor for workers while using ladders, because they are required to maintain static postural balance on platforms of a restricted size. This study observed center of mass (CoM) and center of pressure (CoP) behaviors and evaluated the effects of the platform depth (anterior–posterior length) and working postures. Methods: Eleven male participants stood on four platforms with depths ranging from 6 to 15 cm and maintained their positions for 60 s while performing or not performing other tasks (object holding, upward viewing, or both simultaneously). The kinematics were analyzed on the sagittal plane based on the inverse pendulum model. Results: The absolute moving range for the CoP–CoM linearly increased with the decreasing platform depth, and the working postures affected the slopes of the linear fits. The relative range of CoP–CoM displacement on narrow platforms was highly correlated with the subjective sense of instability. Conclusions: Monitoring the CoP is effective for a better understanding and evaluation of static postural balance. This study’s findings contribute to improving the design of work equipment through the use of wider platforms that are robust against the effects of working postures.

Abstract Bearing capacity of the working platform for heavy tracks was analysed using Distinct Layout Optimization (DLO) method. The platform layer constructed from cohesionless soils is resting on weak cohesive subgrade. Different thickness of the platform, its effective angle of internal friction and undrained shear strength of the soft soil were taken into consideration. Kinematic method permits different failure mechanisms to be analyzed. Margin of safety for a given load and subsoil conditions was determined using two approaches: increasing the load or decreasing the shear strength up to failure. The results were compared with solution proposed in BRE recommendations.

Résumé :

This paper discusses the status and implications of the employment relations and working conditions experienced by digital platform workers; the analysis is based on a survey conducted in 2017 on 1 338 workers engaged in work-on-demand via apps (WODVA) from 25 platforms in Beijing, of whom 48.8 % are full-time WODVA workers or take WODVA as their primary job. The survey ﬁnds that nearly a half of the respondents engage in platform work due to a lack of employment opportunities in formal labor markets or their permanent jobs providing insufﬁcient income. The respondents reveal substantial decent work deﬁcits in representation, compensation, job stability, social protection, working time, and health and safety: 1) WODVA workers seldom have any voice in labor dispute settlements and have a very low rate of unionization; 2) about one third of the full-time WODVA workers cannot earn a living wage and 7.6 % of them earn less than the minimum wage level; 3) three quarters of the full-time WODVA workers have no labor contract with the platforms or other employers, nor access to employer-contributed social insurances; 4) overtime work and underemployment coexist among full-time respondents, with nearly 10 % working for fewer than 4 hours per day while nearly 10 % work for more than 11 hours per day; 5) a majority of respondents run a higher risk of occupational health or physical risks, without any protection provided by the platforms or employers. To promote decent work by digital platform workers, the State needs to establish a portable social security system extending to all workers, to facilitate association and collective actions of platform workers either by extending the outreach of traditional unions or fostering new forms of organizations, to leverage digital technology to facilitate platform workers’ organization and information sharing, and even to promote universal basic income and a workers’ cooperative of platforms in the long run.

Résumé :

Many workers have been drawn to the gig economy by the promise of flexible, autonomous work, but scholars have highlighted how independent working arrangements also come with the drawbacks of precarity. Digital platforms appear to provide an alternative to certain aspects of precarity by helping workers find work consistently and securely. However, these platforms also introduce their own demands and constraints. Drawing on 20 interviews with online freelancers, 19 interviews with corresponding clients and a first-hand walkthrough of the Upwork platform, we identify critical literacies (what we call gig literacies), which are emerging around online freelancing. We find that gig workers must adapt their skills and work strategies in order to leverage platforms creatively and productively, and as a component of their ‘personal holding environment’. This involves not only using the resources provided by the platform effectively, but also negotiating or working around its imposed structures and control mechanisms.

Résumé :

How might analytic reasoning in intelligence reports be substantially improved? One conjecture is that this can be achieved through a combination of crowdsourcing and structured analytic techniques (SATs). To explore this conjecture, we developed a new crowdsourcing platform supporting groups in collaborative reasoning and intelligence report drafting using a novel SAT we call “Contending Analyses.” In this paper we present findings from a large study designed to assess whether groups of professional analysts working on the platform produce better-reasoned reports than those analysts produce when using methods and tools normally used in their organizations. Secondary questions were whether professional analysts working on the platform produce better reasoning than the general public working on the platform; and how usable the platform is. Our main finding is a large effect size (Cohen’s d = 1.37) in favor of working on platform. This provides early support for the general conjecture. We discuss limitations of our study, implications for intelligence organizations, and future directions for the work as a whole.

Résumé :

This article investigates the logics that underpin music curation, and particularly the work of music curators, working at digital music streaming platforms. Based on ethnographic research that combines participant observation and a set of interviews with key informants, the article questions the relationship between algorithmic and human curation and the specific workings of music curation as a form of platform gatekeeping. We argue that music streaming platforms in combining proprietary algorithms and human curators constitute the “new gatekeepers” in an industry previously dominated by human intermediaries such as radio programmers, journalists, and other experts. The article suggests understanding this gatekeeping activity as a form of “algo-torial power” that has the ability to set the “listening agendas” of global music consumers. While the power of traditional gatekeepers was mainly of an editorial nature, albeit data had some relevance in orienting their choices, the power of platform gatekepeers is an editorial power “augmented” and enhanced by algorithms and big data. Platform gatekeepers have more data, more tools to manage and to make sense of these data, and thus more power than their predecessors. Platformization of music curation then consists of a data-intense gatekeeping activity, based on different mixes of algo-torial logics, that produces new regimes of visibility. This makes the platform capitalistic model potentially more efficient than industrial capitalism in transforming audience attention into data and data into commodities.

Purpose The purpose of the study was to explore facilitators and barriers to self-management behaviors in adolescents with type 1 diabetes (T1D) to inform the development of an mHealth platform. Methods Eight adolescents with T1D, 9 parents, and 13 health care providers participated in separate focus groups that explored teen self-management behaviors. Results Adolescents and their parents have distinct preferences for handling diabetes management and use of mHealth technologies. Health care providers support the use of new technologies yet acknowledge concern meeting the potential increased volume of communication requests from teens and families. Conclusion Stakeholders agreed that an ideal mHealth platform would facilitate open communication between teens and their care network and easily integrate with other diabetes technologies. Future directions include incorporating additional feedback from stakeholders to build and modify the mHealth platform. The use of mHealth platforms could be integrated into clinical practice to optimize self-management and support communication between educators, providers, and families in between clinic visits.

The regulation of platform employment is an important issue concerning the labor market as a whole and its individual actors. Currently, regulation is provided by the platforms themselves. Such forms of regulation can lead to unfair competition between platforms, the problem of confidentiality of personal data, information asymmetry. Despite the potential of digital labor platforms in terms of providing new employment opportunities, the elements of precarious employment with the development of platforms are expanding their penetration into the sphere of labor relations. Thus, improving the quality of working life will require government intervention and labor compliance. It is necessary to create legal norms that provide basic protection for workers, transparency and equal conditions for all participants in platform employment. This is recognized by both labor market experts, labor unions, and politicians. The article analyzes the international experience in regulating digital labor platforms. The necessity of regulation of platform employment is substantiated. A number of practical recommendations relevant to the Russian Federation have been made, problem fields have been identified that require further research.

Résumé :

Purpose The purpose of this paper is to show that gig jobs could be considered an alternative way, albeit not the very best, to give work opportunities to older people. This could offset the continuously decreasing income from the pay-as-you-go pension system, which remains the main source of income for older Hungarians. Design/methodology/approach The paper reviews the most important aspects of employment of older people and highlights the digital divide which still restricts their participation in the labor market. The paper analyzes data from the Hungarian carpooling company Oszkár and compares it with official statistical data from the Hungarian labor market, focusing on the dynamics of the employment of older persons. Findings The findings show that the alienation of older workers from the gig economy is just transitory, and that an increasing proportion of older gig workers can be anticipated. Research limitations/implications Compiling data on the gig economy faces a number of obstacles, as enterprises are disincentivized from revealing all their data. Social implications Older people are more likely to be employed in lower-quality jobs, such as own-account self-employed. They are also increasingly more likely to become gig workers. Originality/value The paper articulates the importance of remaining active as one ages and moreover challenges the traditional belief that gig jobs mainly offer opportunities to the younger generations.

Résumé :

This article discusses the evolving trend of mobile applications and their increasing use by engineers. With the help of mobile applications for smartphone and tablet, engineers are discovering innovative ways to work that don’t have them tied to their desks. Apps allow engineers to bring drawings with them while on the road, to collaborate with other engineers, and to access information on the shop floor or in the field. Due to the very nature of the mobile platform on which they sit, applications can’t be used at every job. Their adoption depends on the type of work, the work environment, and employees’ attitude. If enough employees do have their own personal devices, there are apps that let employers update employees on the shop floor or in the field. Many engineers use mobile applications to collaborate with their design-team members or to show others, like customers or suppliers, how a product will look or will function. Engineers can also share computer-aided design drawings, design work, spec sheets, and the like through the technology.

Résumé :

Digital platform capitalism, as exemplified by companies like Uber or Lyft has the potential to transform employment and working conditions for an increasing segment of the worforce. Most digital economy workers are exposed to the health damaging precarious employment conditions characteristic of the contemporary working class in high income countries. Just as with Guy Standing or Mike Savage’s “precariat” it might appear that digital platform workers are a new social class or that they do not belong to any social class. Yet the class conflict interests (wages, benefits, employment and working conditions, collective action) of digital platform workers are similar to other members of the working class.

Résumé :

In order to improve the precision of machining and reduce the processing cost of paper honeycomb core, a new method is presented to fix the honeycomb core work piece to the working platform using magnetic and frictional forces. In this method, iron powder is used as a medium instead of the traditional adhesive-based material to achieve the bonding between the work piece and the working platform. Iron powder is poured into honeycomb cells until it reaches the desired height using a numerically controlled iron powder feeder system. In addition, a magnetic working platform is manufactured and placed on top of the station of the milling machine. The magnetic field produced by the magnetic working platform is leaded to the iron powder while the magnetic field control system switches on. More precisely, the mutual magnetic attraction between the iron powders located in different cells of the honeycomb and between the iron powder and the platform is generated. While cutting force is applied to the work piece, two types of friction force occur. One is between the iron powder and the wall of the honeycomb cells, and other one is between the work piece and the working platform. Once the resultant friction force balances the machining load, the work piece will be then fixed to the platform. In this paper, a new bonding system based on the new method is introduced and demonstrated.

Résumé :

The so-called ‘platform economy' or ‘gig economy' and its ambivalent effects on the working environment is a focal point of social science research. The contribution analyses, based on a case study, algorithmic work in the platform economy, its working conditions, and the way gig workers organised and articulated their protest. The algorithmic management of Lieferando (formerly Foodora) governs its employees through algorithmic-driven and standardized work coordination. Therefore, different conflicts between the company and its workers arose, concerning working conditions, working relations, and co-determination. Organising, protest, and established co-determination mechanisms play a crucial role for the employees. As a result, there exists currently a few institutionalized relationships between the platform and its workforce in Germany.

Résumé :

Abstract Digital labour platforms, encompassing on-demand translation work via apps and websites, have grown exponentially in recent years and have significant consequences for translation workers. This study explores the critical literature on digital labour platforms from a labour studies perspective and submits the findings of a quantitative survey of 70 translation workers residing in Turkey and working on/for digital labour platforms. Our research suggests that the introduction of digital labour platforms into translation production and business networks has not yet provided a significant contribution to the working conditions of translation workers in Turkey. Instead, we argue that their working conditions have been rearranged and reorganized in accordance with the uberization of (translation) work. According to the survey findings, engaging in such work on/for digital labour platforms exposes translation workers to risks related to employment status, income level, work-life balance, social protections, free agency, bargaining power, dependence on the platform, allocation of risks and rewards, and data collection, protection and privacy.

Résumé :

In his 1872 The housing question, Friedrich Engels addressed the housing problems faced by the proletarian migrant workers in major industrial centres. He asserted that they could only be solved by first resolving their harsh working conditions in the capitalist mode of mass production. Presently, with transnational migrant flows to urban centres and the mass acceptance of the digital platform economy, the housing question manifests itself, among other expressions, in the case of immigrants working in this digital contract-based market. While the platform economy provides immigrants with quick access into a host country’s labour market, the income insecurity and high risks associated with such work put them in a state of precariousness. Through the framework of Engels’ proposed action lines and analysis of observations and interviews with immigrant riders working for the food delivery platforms Glovo and Deliveroo, the paper highlights the negative impacts that this contemporary capitalist model of work, the municipal housing plan and the ongoing Covid-19 crisis have on the immigrant riders’ residential and working conditions in Barcelona, Spain, a city facing a severe rental housing shortage. Lastly, it suggests that, while the social market economy in Spain can be reformed to ameliorate the negative impacts of the platform economy on immigrant riders, bridging the gap between immigrant housing provision and employment inclusion would need to consider decent labour and housing as rights for residents, immigrants included, asserting the currency of Engels’ ideas.

Résumé :

It is known that vibratory feeders are the most versatile of all hopper feeding devices for small engineering parts and play a key role in assembly automation. However, there are still no reliable and effective professional teaching platforms for researching or demonstrating the principle of the parts conveying. The aim of this paper is to develop an optimal teaching platform based on the analysis of the working principle that the feeder follows. The structural design, elastic system and control system are studied in this paper. The vibration principle is verified by the teaching platform through the experiment and the results are promising.

Résumé :

Purpose. Creation of technological schemes ofdevelopment of steeply inclined layers in the conditions of the formation of edges of deep iron ore pits during the development of deep steeply dipping deposits in order to determine the width of the working platform. The research of the methodology consists in the development of new technological schemes and the use of existing schemes for the development of benches in the conditions of steeply dipping deposits. The next step is determining the width of the working platform, depending on the layout of the main equipment and the sequence of working off the bench. At the same time, the selected equipment allows to determine the parameters of the working platform of bench. For selecting the equipment, four options of equipment were distinguished according to the averaged parameters of modern mining machines, i.e. the method of averaging indicators was used. Findings. New technological schemes have been developed, as well as existing technological schemes have been used to substantiate the width of the working platform during the formation of steeply inclined layers on the deep edges of pits during the development of deep iron ore deposits. A technique was created that allows you to preliminarily determine the width of the working platform using a nomogram that takes into account the height of the bench, one of the options of equipment that can be used in the development of the bench and the scheme of development. The originality. Graphic dependencies were established for determining the width of the steeply inclined layer. These dependencies will be used during the development of the pit edge. Based on the obtained dependencies, taking into account the formation of technological schemes, it is possible to determine in advance what the width of the bench. Also, the complex mechanization (options 1-4) and the scheme with different heights of the bench are used, which allows to determine the most promising schemes of development, and in the future the rate of change in the level of areas of the steeply inclined layer. Practical implications. The possibility was established by a graphical method to determine the optimal width of the working platform or layer on a separate horizon or within a block, using complex mechanization. The results allow to prepare data (mining flowsheet bench (s), a width platform (layer) by selecting the equipment suitable to work on the bench with the corresponding parameters) for further design of the staged development of steeply inclined layers of deep open pits.

Résumé :

Purpose The purpose of this paper is to investigate the impact of virtual community trust on work engagement and person–job fit in the context of digital work platforms. The emergence of the platform economy is changing the work environment fundamentally. It has enabled the appearance of alternative work arrangements, such as temporary organizing and the increase of independent contracting, also among highly specialized knowledge workers. Design/methodology/approach Data were collected with an online survey and used to test the relationships between virtual community trust, work engagement and person–job fit. Confirmatory factor analysis and structural equation modeling were used to test the goodness of a theoretical model. Findings Based on the data of 127 experts contracting on digital work platforms, virtual community trust positively affects both work engagement and person–job fit. In addition, the relationship between work engagement and person–job fit in the context of digital work platforms is significant and positive. Practical implications This study shows that trust among independent contractors working on digital platforms is important for work engagement and that platform providers can improve work performance through person–job fit by assisting in the creation of trust among members of their platforms. Originality/value The research literature on knowledge work in the changing context of work is scarce, and the role of trust in the context of digital work platforms needs clarification. This paper tests a theoretical model on the effects of trust among highly skilled experts working in the digital platform context as independent contractors and provides evidence for the importance of building trust among members of a virtual work community.

Résumé :

We all aspire to urbanism that recognizes the social, economic, political, cultural and physical-spatial dimensions of cities. Urbanism, which, based on working tools (SDAU, Planning Regulations, etc.) based on a quality model, will allow good practice and good translation of these systems on the territory (neighborhood, city, rural environment, etc). Due to that, we are interested in our article to propose and develop an automated urban planning management platform for the generation of updates proposed by urban planning experts in order to improve the quality of amenagement regulations.
