BackgroundArts-On-Prescription (AOP) programmes are growing in popularity in European primary care. To meet social distancing rules of the COVID-19 pandemic, AOP workshops were moved onto online video conferencing platformism. It is unknown whether the format (in-person versus online) affects how patients perceive these programmes and their overall success.AimTo investigate the impact of arts programmes on the health and wellbeing of primary care patients and whether the online format affects the accessibility or intended benefit of such programmes.MethodWe conducted a qualitative study at a single primary care centre in Brighton, UK, where numerous AOP programmes are offered. We conducted semi-structured telephone interviews with nine participants. Interviews were audio recorded and subsequently transcribed verbatim. Transcriptions underwent thematic analysis by two independent researchers, first independently, then collaboratively.ResultsThe online format provided ‘a form of meeting people in a safe environment’ for those shielding from COVID-19. Some participants preferred the online format to face-to-face workshops, particularly those with physical disabilities or social anxiety. Teething issues with the technology at the start were reported by some. Participants greatly value the service, reporting numerous benefits to social, physical, and mental wellbeing (particularly in addressing anxiety symptoms). Workshops such as singing and dancing helped the management of chronic physical symptoms.ConclusionParticipants valued the workshops as a space for peer support and patient empowerment. These findings must be viewed in the context of social isolation arising from lockdown. Online delivery offers potential for widening access to arts interventions. Further research should explore the opinions of vulnerable groups.

Recent advancements in Digital Communication Systems and Web Technology tendered information systems cheaper and allow people to move into the electronic Government (eGov) platforms. eGov is the use of information and communication technologies (ICTs), whereas good governance refers to how well public authorities manage public and social resources. eGov supports excellent governance practices, yet it also has certain limitations. In this article, we enhance the study of Jiyuan City’s Internet-based e-government system based on an analysis of theoretical knowledge and application state. First, we gathered all government affairs platform websites; then, we built the supervision system function code in accordance with the supervision system activity diagram. Finally, the office platform's system deployment was completed, and the government office platform’s analysis environment was provided, and it was validated via experiments. The experimental results show that when there are 300 government affairs tasks to be handled, the data recall rate of the design platform’s government affairs website is 95%, and the design platform’s government affairs processing time is 15 minutes. The proposed government affairs platform has a high processing efficiency and data-carrying capacity.

Using a game-theoretical approach, this paper develops a duopoly model and examines value-added service (VAS) investments and pricing strategies on video platforms with opposite inter-group network externalities between two groups. We consider two scenarios with VAS investment, namely, a single platform investing in VASs for advertisers (S-Model) and both platforms investing in VASs for advertisers (B-Model). We found the following: (i) In the S-Model, the investing platform’s VAS level remains maximum when the marginal investing cost is low; otherwise, it decreases with the cost. Investing and non-investing platforms’ advertising prices are unaffected by the marginal investing cost if the cost is low; otherwise, the prices decrease and increase with the cost, respectively. Furthermore, the investing platform’s advertising price is higher than the non-investing platform’s. (ii) In the B-Model, the two platforms’ VAS levels remain maximum if the marginal investing cost is low; otherwise, they decrease with the cost. The two platforms’ advertising prices are equal and irrelevant to the marginal investing cost. (iii) The investing platform’s VAS level in the S-Model is higher than or the same as that in the B-Model and the investing platform’s advertising price in the S-Model is higher than that in the B-Model. (iv) Compared to the scenario without VAS investment, the investing platform’s advertising price is higher in the S-Model, but the same in the B-Model.

Security requirements are more demanding in the e-commerce domain. However, mobile e-commerce settings not only insist on security requirements, they also require balance between security levels and hardware and usability device ability. These features require designing models having simple authentication and authorisation scheme which also ensures information integrity for each e-transaction. The Mobile and Wireless Applications’ Development Interest Group W@Pcolombia thus developed the P3SIM platform so that mobile applications might include SIM parameter-based security features. The P3SIM platform’s framework and compilation and simulation settings combines the advantages of identification provided by the SIM module with the security features provided by SATSA and Java Card APIs for Java ME environments, one of the most-used platforms for mobile application development. Developing an m-commerce-based prototype not only shows the platform's ability to operate in secure environments, it also shows its ability to comply with environmental security requirements.

Abstract Digitalization has been changing the methods of production, distribution, and use of written and audiovisual products, according to a process of “platforming”. Most audiovisual content is available via streaming platforms, through a lot of devices (PCs, tablets, smartphones, smart TVs, and videogame consoles), which have empowered the process of media convergence. Based on a theoretical framework related to the impact of the platforms on the ongoing process, we intend to analyse how platforms are changing the identity of the audiovisual industry and how they represent themselves online. In order to analyse the ongoing process, we intend to examine some platforms that could be considered as best practices in the audiovisual field: Netflix, MUBI, and Festival Scope. On the one hand, using these platforms as case studies will enable us to highlight some beneficial aspects of the ongoing process of digitalization and platforming: holding many gazes and points of view; catching market niches; building a peer-to-peer network. On the other hand, we intend to emphasize some risks connected to the intermediation of platforms in the audiovisual field in terms of economic, cultural, and social effects.

Using the organization information processing theory, we explored the process through which the informative support of crowd logistics platforms affects logistics performance. After collecting data from 321 respondents from two crowd logistics companies in China, we proposed and tested the theoretical framework empirically using SEM. To conduct the empirical study, we developed scales for platform’s informative support and the degree of logistics resources-demand match, respectively. The results indicate that a platform’s informative support improves logistics performance via two mediators, i.e., logistics resources-demand match and logistics agility. Moreover, a platform’s ease of use moderates the indirect process through which its informative support promotes logistics performance via logistics resources-demand match. However, a platform’s ease of use has no significant effect on the indirect process of its informative support affecting logistics performance via logistics agility. This paper extends our understanding on how the informative support of crowd logistics platforms predicts logistics performance.

Smart city platforms provide several services to facilitate the development of applications. Such platforms typically manage several applications, deal with a large volume of data, and serve many devices and users that generate a high volume of requests. The large number of requests to handle and the complex operations to perform often cause overloads on the platform, degrading the quality of service provided to users and applications. In this context, monitoring the underlying computational infrastructure in which smart city platforms and applications are deployed and the platform operations is essential. The monitoring process can allow for examining fluctuations in the behavior of the platform's components to detect performance degradation and overloads (including unforeseen ones), contribute to avoiding interruptions in the platform's services, and increase its scalability to assimilate significant amounts of requests, devices, and users. This paper presents a strategy and architecture to enable the non-intrusive monitoring of operations on smart city platforms and their underlying infrastructure. The proposal covers monitoring at multiple levels and is based on the aspect-oriented programming (AOP) paradigm so that it is possible to monitor the platform's operations without intervening in the platform's implementation or generating coupling regarding monitoring. This paper presents the implementation of the monitoring architecture and its instantiation in the context of Smart Geo Layers (SGeoL), a platform that has been used in several real-world smart city applications. This paper also reports the results of computational experiments to evaluate the performance of the proposed monitoring architecture for response time to requests, CPU usage, and RAM utilization. The obtained results show an evident increase in response time with the number of simultaneous requests and a significant correlation between the response time and the CPU utilization in the deployment of the monitoring architecture.

This study explores the factors that influence experts’ regular contribution to educational community question-answering (CQA) platforms. Providing answers is essential for sharing knowledge on CQA platforms, but it also affects learners’ progressive inquiry. Therefore, the purpose of this study is to develop and test a theoretical model that aims to explain which factors influence whether experts answer questions on educational CQA platforms and how these factors correlate with each other to form a “map” of experts’ respective behavior. We examined experts’ perceptions of three dimensions: the CQA platform’s usability, the quality of questions asked, and the added value of answering these questions. We examined the factors involved in these dimensions from the perspective of the Theory of Planned Behavior to connect them with the experts’ perceptions, intentions, and actions on a CQA platform. As our case study, we took the 100mentors web and mobile app, a small-scale platform that addresses learning communities around the world, and we conducted a survey for their registered experts (N=126). The factorial structure indicated that experts first perceived the question quality mostly based on its relevance to their expertise or experience (question quality); secondly, that their intention to answer was mainly set by their motives to make a difference for the learner and partially by the user-friendliness of the platform (added value of answering and CQA platform’s usability); and finally, that their actions were connected to the regular use of the platform for answer-sharing (CQA platform’s usability). A future research challenge is to test the factorial structure in large-scale educational CQA platforms. The further confirmation of the expert behavior pattern can have a practical implication for the platforms to guide their expert community more efficiently and for the learners to pursue their learning through progressive inquiry.

A diverse assemblage of adult reef fishes and invertebrates occurs at offshore oil production platforms in the Southern California Bight (SCB). Coincident with the initiation of the decommissioning of six platforms in the SCB, the goal of this study was to examine how a platform's geographical location plays a role in its potential contribution of larval recruits to natural areas. Using a three-dimensional biophysical model, we quantified the potential connectivity of larvae, particularly relevant to reef fishes, from three offshore platforms to four coastal shelf regions where the majority of rocky settlement habitat occurs in the SCB. The regions cover the shelves of the mainland coast and islands and offshore banks in the southern SCB. The main findings indicate that (1) the potential for larval subsidies from platforms in the southern SCB to populations in the northern SCB are greater than the potential for larval subsidies from platforms in the northern SCB to the southern SCB; (2) there is greater seasonal variability of potential connectivity from platforms to the mainland shelf region of the northern SCB than to the mainland shelf region of the southern SCB or shelves around islands and banks; and (3) there is consistency across years in the relative magnitude of potential connectivity from the platforms to the four shelf regions. We conclude that a platform's function as a larval source should be considered an ecological criterion when evaluating whether a platform is to be converted to an artificial reef and implementing marine spatial planning.

Purpose. The study is aimed at defining the nature of platforms in multi-sided markets in order to find the price optimization model for platform’s goods and services. Methodology. The article used general scientific and special research methods. The generalization of the main methodological approaches to the study of the essence of multi-sided markets, the identification of factors affecting the platform’s pricing strategy were based on the methods of dialectics, scientific abstraction, and systemic analysis. The basis of the study of the essence of “platforms” was laid on the use of the following methods: analysis and synthesis, induction and deduction, generalization. Economic and mathematical modeling, scientific abstraction, systemic structural analysis contributed to the development of our own model of the optimal strategy for choosing the price of goods and services by platforms. Findings. The article defines factors that affect the pricing of platform’s goods and services. An economic and mathematical model has also been developed to determine an optimal strategy for choosing the price in terms of Nash equilibrium. There have been identified three main factors, which produce the most significant impact on the price of goods and services of platforms: marginal costs; rate of return of another product is being implemented by the platform; elasticity of demand and price. Practical implications. In the conclusions, not only the advantages but also the limitations of the proposed economic and mathematical model have been pointed out, which can be addressed in further studies and implemented into specific living model of economic decisions while price optimization model for platform’s goods and services in multi-sided markets. Originality/value. The article is generalizing the previous experience within the niche of price optimization model. Also authors have developed their own economic and mathematical model of the optimal strategy for choosing the price for the platform’s products or services, which enabled us to identify its dependence on 3 main factors: marginal costs, rates of profitability of other products sold by the platform, elasticity of demand and price. These results can be overcome in future studies. The results and conclusions have been done by the authors and are totally original.

After the COVID-19 pandemic has subsided, the catering industry has returned to its previous thriving scene. Many restaurants have launched group buying services and collaborate with third-party online platforms to attract more customers. For the optimal decisions and maximum profits of restaurants and online platforms, a two-layer supply chain model is designed to investigate and study the price strategies and service strategies. Considering the service levels of restaurants and platforms, we construct the mathematical expressions of the offline retail model, online retail model, and online group buying model, respectively, and solve the game equilibrium. The results are shown as follows: (1) With cooperation between the restaurant and platform, both the restaurant and platform can obtain their maximum profits when they apply optimal pricing strategies. (2) The optimal pricing strategies of the restaurant are influenced by the sensitivity coefficients of customers to the restaurant and platform’s service levels, and the cost coefficients of the restaurant and platform’s service levels. (3) The maximum profit of the restaurant is directly proportional to the number of new potential consumers who are attracted. The more potential consumers who are attracted, the higher the profit the restaurant earns. The research results provide a reference for restaurants and platforms to formulate price strategies and service strategies, to help restaurants and platforms achieve more profits.

The proliferation of visual impairment among school-age children in Indonesia has prompted the need for specialized online learning solutions. The G-MOOC 4D platform, a novel Learning Management System (LMS), is designed to address this need by leveraging gamification and artificial intelligence to enhance accessibility for visually impaired users. This study reports on the development and testing of two AI models within the G-MOOC 4D framework: a facial recognition model for secure user authentication and a voice command model for interactive learning. User Acceptance Testing (UAT), conducted with expert users, namely teachers at a special needs school, showed high approval rates for the platform's features. The results show that all metrics, accuracy, precision, and recall reach their optimal values at a distance of 40 cm for face detection. The respective metric scores at that distance, precision: 100%, accuracy: 98%, and recall: 97%. Additionally, the voice command functionality tested achieved a 100% recognition rate, reflecting the platform’s potential to significantly ease the learning process for visually impaired students. The findings underscore the importance of integrating assistive technologies into educational platforms to ensure all students have equal access to learning opportunities.

Regarding digital platforms in recent years, the abuse of a platform’s dominant position, applications monitoring user behaviour, the difficulty of exiting digital platforms, and the inability of users to transfer data on platforms have become increasingly acute, which makes the evaluation of the openness of digital platforms extremely urgent. This paper applies the relatively objective entropy-weighted TOPSIS method to construct a digital platform openness index (DPOI) to evaluate the openness of 22 digital platforms in China. The research found that there are certain institutional constraints and obstacles in the access, transaction, exit, and transfer of different types of digital platform, and it is necessary to sustainably improve the openness of digital platforms to bring convenience to users in the future. Our results not only update the practical data on the openness of emerging digital platforms, but also enrich the literature in the field of digital platform openness, which has significant implications for evaluating the openness of digital platforms in emerging markets such as China.

One of such phenomena is the development of communication platforms, which are separated into an independent definition and depart from Internet platforms and social networks. It is important to study the development of platforming as a process of forming platforms of different types and cluster formation.Research methods.The method of theoretical analysis is used to study the existing points of view and clearly derive the definition of «communication platform».A method of comparison to derive the author's vision of the existence and functioning of the characteristics of the definition of «Communication Platform»and distinguish it from other types of platforms.The method of sociological survey contributed to the practical vision of the communication platform as an independent unit that is able to raise socially important issues and help solve difficult issues.The resultsof the study showed the difference between the terms «Social Networks»and "Communication Platform". There is a classification of platforms, the difference between them. The own vision of the terminological unit is given. This approach demonstrated the need for further scientific study of the phenomenon, the need to unify the approach to the description of platforming as a process in applied social and communication technologies.Social networks as a communication unit are considered in detail, the features that distinguish platforms and social networks are described.The conclusionsemphasize the further need to study communication platforms as applied scientific units. The definition of the phenomenon taking into account the author's vision is offered. Emphasis is placed on the features inherent in communication platforms.

Platforms that intermediate trades—such as Amazon, Airbnb, and eBay—play a regulatory role in deciding how to govern the marketplaces they create. We propose a framework to analyze a platform’s nonprice governance design and its incentive to act in a welfare-enhancing manner. We show that the platform’s governance design can be distorted toward inducing insufficient or excessive seller competition, depending on the nature of the fee instrument employed by the platform. These results are illustrated with micro-founded applications to a platform’s control over seller entry, information provision and recommendations, quality standards, and search-design choices.

Abstract This study describes a spatial model of price discrimination in two-sided media markets. Given that media platforms offer a uniform price for consumers and either a uniform or discriminatory price for advertisers, we compare a platform’s profit and welfare under these two different pricing schemes. In contrast to the well-known result that price discrimination based on a consumer’s location leads to lower profits, if consumers have a strong aversion to advertising, we show that a platform’s profit is better off under price discrimination. In addition, if consumers rather dislike advertising, we show that price discrimination is detrimental to both a platform’s profit and the consumer’s welfare.

In the two-sided market for online streaming content, the platform’s co-opetitive strategy has been wildly discussed, where the platforms cooperate in sharing the broadcasting right of content and meanwhile compete for both subscribers and advertisers. Although platform co-opetition in practice can be easily captured, the impacts of cross-side network effects on pricing strategy are contingent upon the participation decision of both sides, including single-homing and multi-homing. Therefore, we examine the optimal co-opetitive strategy of duopoly platforms using a Hotelling model to capture user behaviors and investigate the equilibriums of pricing decisions and profits in three scenarios: single-single, multi-single, and multi-multi. The main findings are: (1) Advertisers choose multi-homing only when subscribers are also multi-homing, and the broadcasting cost is relatively low. (2) With single-homing advertisers, the primary broadcasting platform earns more profit than the re-broadcasting one. (3) With multi-homing advertisers, the primary broadcasting platform’s profit increases with the broadcasting rights cost. (4) Platforms should focus on building strong cross-side network effects with multi-homing advertisers. Alternatively, they would be better off contracting with single-homing advertisers if the effects are relatively low.

This article analyses the recent case law concerning Uber and other platforms. Its main objective is to examine the question of whether and under what conditions platforms can be considered the contract partners of the individuals who seek goods and services through the platform’s infrastructure. In a first step, the criteria employed by the courts, both the Court of Justice of the European Union and national courts, are identified that characterise the role of platforms in relation to the underlying service provision. In a second step, the article looks at the approach to intermediaries in more traditional consumer contract law. A differentiated image emerges, which underlines the need for legislative clarification.

Purpose Faced with environments rife with technological uncertainties, software platforms have gained interest as enablers of innovative businesses and development processes. While extant research has focused on mature platforms, the authors know less about the early phases in a platform’s life cycle. Drawing inspiration from the effectual perspective on entrepreneurship, the purpose of this paper is to further the understanding of how software platforms are established. Design/methodology/approach The authors develop a framework that describes four types of entrepreneurial awareness and then apply it to a qualitative case study of a platform that has emerged from the initial “creation” phase and is now in a period of rapid growth. Findings The study indicates that successful establishment of a software platform depends upon the provider’s ability to integrate business acumen with technical proficiency and leverage these combined skills to ensure short-term viability and long-term relevance in the market. Research limitations/implications This paper contributes to literature on platform strategy, which has previously focused on mature platforms, by addressing entrepreneurial behavior during a software platform’s establishment. As it is based on a single qualitative study, additional studies of different platforms are needed to verify the results. Originality/value The paper highlights the dependence of software platform establishment on the ability to enact both explorative and exploitative activity patterns, and embrace both strategic foresight and systemic insight cognitive patterns. The combined patterns of activity and cognition form four types of awareness, pertaining to markets, resources, technology and contexts.

How do historically marginalized narratives spread on social media platforms? Developing research in collaboration with intersectional artists and community, or what we call “platforming intersectionality,” can reveal the promise and limitations of social media for bridging disparate, segregated communities, or “networked solidarity.” Using case studies of indie TV series about historically marginalized communities, we show that intersectionality can spread on corporate social media platforms, but the causes are largely visible outside of platforms, both online and offline. Basic conditions for spreading intersectional narratives may be met when the language used to describe them are simply communicated in ways algorithms and users can quickly understand. However, community members, including artists and publishers who produce for specific communities online and offline, serve as critical, under-appreciated nodes platforms leverage to spread intersectionality. We argue that reconceptualizing platforms as community-based media provides a better framework for understanding the power and limits of social media.

Nowadays, with the rapid development of the platform economy, Big Data-based Discriminatory Pricing (BDDP) has become a common phenomenon in which big data and algorithms are applied to excessively seize consumer surplus and thus damage the rights and interests of consumers. This work aims to explore the equilibrium strategies of the consumers, the government, and the service platform and discuss factors affecting the BDDP practice of the service platforms. This study constructs a tripartite evolutionary game model among consumers, service platforms, and the government. Two evolutionary equilibrium strategies are derived and validated using simulation. Numerical experiments are conducted using MATLAB to reveal players’ evolutionary stability strategies under various settings. The study shows that (1) the strategies of the government and the platform always influence each other, (2) a reasonable adjustment of tax rate helps regulate the platform’s behavior, and (3) the proportion of consumers who switch the platform after they realize themselves suffering BDDP is an important factor influencing platform’s strategy. This study lastly summarizes the managerial insights for dealing with the platform’s BDDP behavior and safeguarding consumers’ rights from the perspectives of macro-regulation and privacy data protection. The conclusions of this study can help promote the high-quality development of the platform economy.

The application of the crowdsourcing model to instant delivery has achieved remarkable success. Various crowdsourced logistics platforms have successfully addressed the challenges of last-mile delivery in urban areas by eliciting the active involvement of the public. This study takes a dual-market perspective and, considering the high requirements of instant delivery for timeliness, introduces two crucial factors: platform subsidies and the degree of public involvement. We establish a pricing model based on the Hotelling model and conduct in-depth research on the platform’s maximum profit and equilibrium pricing under different user attribution conditions. This study reveals that when the dispatching party has a single attribution, the platform can increase profits by reducing the intensity of cross-network externalities or increasing user transfer costs. In cases where the dispatching party has partial multiple attributions and the receiving party has a single attribution, lowering network externalities, increasing platform subsidies, enhancing public involvement, improving platform technical matching rates, and increasing the expected order quantity of the dispatching party all effectively increase the platform’s maximum profit. When both sides of users have partial multiple attributions, increasing public involvement increases the platform’s maximum profit. This research provides new theoretical support for the pricing strategy of crowdsourced logistics platforms.

The digital era has ushered the rise in the utilisation of alternative communication platforms in integrated marketing communications (IMC). The contemporary business environment necessitates employing high-yield communication platforms to help sustain and further an institution’s position in the industry. This paper aims to identify the most efficient platforms employed by the university, accounting the preference of the target audience and the platform’s actual reach through a gauge termed coverage index (CI). Results from net 303 valid responses, gathered via an online survey, show that the following in descending arrangement: relatives/friends, open house, social media, and university website are in the upper quartile (CI>67.78%). Further, variance analysis uncovered differences in the preference and reach ratings of certain platforms when respondents are classified according to demographic characteristics. Universities then can strategize their IMC applying high CI platforms. Additionally, the segmented approach to marketing can be incorporated depending on the prospective students’ profile.

In most countries, regulation of digital platforms and ecosystemsʼ activities has emerged quite recently. This regulation should take into account the specifics of platform business models, characterized by network effects, access to big data, assets mobility and lightness, and large economies of scale and scope. This article examines the trends in of the global economy digitalization, as well a factors and directions of digital platformsʼ impact on different economic indicators. The analysis serves as the basis for conceptual recommendations on improving digital platforms regulation in Russia. Key recommendations are related to the development and legislative adoption of definitions for digital platforms and ecosystems, the development of special measures to support national platforms (based on certain criteria for their classification as national enterprises), the amendment in and improvement to antimonopoly regulation, the establishment of interdepartmental coordination and interaction with relevant stakeholders

Competition to become one of several dominant mobile platforms is intense. Platforms compete for developers, who create applications which make the platform valuable for users. Why doesn't one form of platform governance emerge as superior? This essay will stress the reasons for differentiation and proposes a new argument linked to a platform's “hierarchy.” Hierarchical governance features can help at one moment but then get in the way at a later time. These arguments are illustrated by different approaches to platform governance taken by the major mobile platform sponsors of recent years.

AbstractWe analyze the impact on consumer prices of some information characteristics of price-comparison search platforms. An equilibrium model where vendors compete in prices and consumers do not observe prices, but can obtain price information through a search platform, is developed. The model generates several predictions about the impact on the price distribution of: (i) the size of the search platform’s sample, (ii) whether the search platform’s sample is random, and (iii) the number of vendors in the market. The model’s predictions are tested experimentally. The results confirm the predictions about (ii) and (iii), but reject the model’s predictions about (i).

The present study argues that political communication on social media is mediated by a platform’s digital architecture—the technical protocols that enable, constrain, and shape user behavior in a virtual space. A framework for understanding digital architectures is introduced, and four platforms (Facebook, Twitter, Instagram, and Snapchat) are compared along the typology. Using the 2016 U.S. election as a case, interviews with three Republican digital strategists are combined with social media data to qualify the study’s theoretical claim that a platform’s network structure, functionality, algorithmic filtering, and datafication model affect political campaign strategy on social media.

Digital platforms disrupt today’s industries with novel offers and business models. Despite their revolutionizing impact, over 80% of platforms fail. To better understand what differentiates failing from successful platforms, we identified 30 platform success factors. These range from corporate value integration, where the platform strategy gets defined and the platform’s value definition, to the platform architecture covering all essential IT considerations and best practices making, e.g., innovation and personalization possible. To make these success factors usable in practice, we integrated all 30 success factors into the wellestablished Business Model Canvas (BMC) widely adopted for business model design. This method was chosen to test the applicability and usefulness of the platform success factors in a widely used vehicle and thus ease our workshop study. The success factors are promising, as demonstrated in our workshop study.

The Scientific and Technological Innovation Platform (hereafter S&T innovation platform) accumulates rich innovation resources, co-ordinates the interest between multiple innovation subjects, promotes the sharing of innovation resources, and thus enhances the platform’s network innovation capability. Therefore, based on the perspective of the target positioning of the S&T innovation platform, this paper explores the improvement path of the platform’s network innovation capability. Through empirical research, we found that the target positioning of the S&T innovation platform helps to improve the platform’s network innovation capability. The mediating mechanism of construction logic and transformational logic enhances the S&T innovation platform’s network innovation capability. At the same time, this paper studies the influence of boundary factors, such as government guidance and market lead, on the network innovation capability of S&T innovation platforms and finds that the market lead moderating effect impacts the network innovation capability of S&T innovation platforms through commercial logic and transformational logic. The government guidance positively moderates the relationship between the target positioning of the S&T innovation platform and the commercial logic under construction logic. The moderating effect under the joint impact of market lead and government guidance enhances the network innovation capability of the S&T innovation platform using social logic and transformational logic. The novelty and uniqueness of the research are based on the innovation network theory, integrating construction logic and transformational logic, and enriching the boundary conditions to enhance the network innovation capability of the S&T innovation platform by introducing the roles of market lead and government guidance.

This paper aims to examine what factor relevancy influences consumers’ preference to use online food delivery platforms in Thailand. Further, it investigates consumers' behavior during the covid-19 pandemic. A questionnaire was used to examine a sample of 400 Thai consumers who were using online food delivery platforms. Collected data were analyzed using a statistical package program in 3 steps: Confirmatory factor analysis, path analysis, structural equation model analysis (SEM). Thai consumers increasingly used food delivery on online platforms during the covid-19 epidemic. The study also found that the platform's ease of use, the food delivery service fees, offers or privileges, and payment security on online food delivery platforms influenced consumers’ future use of online food delivery platforms. The food delivery service fees are the most influential factor in using online food delivery platforms. Future research can explore the role of using online food delivery platforms and their impact on the online food delivery platforms. Online food delivery platform providers should lower their service fees, always be implementing new promotions, provide various coupon codes, and create games so that consumers can win prizes. The online food delivery platform providers need to develop consumer trust, ensure that payments are secure, and enhance the ease of use of their platforms. This study contributes to the emerging literature related to online food delivery platforms by studying the relevancy factor that influences consumers’ preference to use online food delivery platforms, which are critical for the success of any online food delivery platform provider.

Digital platforms that aggregate products and services, such as Google Shopping or Amazon, have emerged as powerful intermediaries to brand offerings, challenging traditional product brands that have largely lost direct access to consumers. As a countermeasure, several long-established brands have built their own flagship platforms to resume control and foster consumer loyalty. For example, sports brands such as Nike, Adidas, or Asics launched tracking and training platforms that allow for ongoing versatile interactions among participants beyond product purchase. The authors analyze these emerging platform offerings, whose potential brands struggle to exploit, and provide guidance for brands that aim to platformize their business. This guidance comprises the conceptualization of digital platforms as places of consumer crowdsourcing (i.e., consumers drawing value from platform participants such as the brand, other consumers, or third-party businesses) and crowdsending (i.e., consumers providing value to platform participants) of products, services, and content along with a well-defined framework that brands can apply to assemble different types of flagship platforms. Evaluating the consequences of crowdsourcing and crowdsending for consumer–platform relationships, the authors derive a typology of archetypical relationship states and develop a set of propositions to help offline-born product brands thrive through platformization.

Purpose – Platforms have been enhancing delivery networks for faster and cheaper delivery, resulting in nationwide coverage. It has been observed recently that platforms raise buyer fees and the share of delivery cost, seemingly damaging the buyer group. This paper aims to analyze economic relationships between homing structure , pricing schedule, and delivery cost to understand unfavorable actions toward buyers. Design/Methodology/Approach – We set up a platform competition model based on the Hotelling location model, and characterize a symmetric Nash equilibrium. Two platforms intermediate two groups and charge fees, single-homing a buyer group and a multi-homing seller group in a one-unit-long city. Findings – A drop in delivery cost increases both the seller and buyer surpluses. Platforms with first degree price discriminatory fees can absorb the entire surplus from a multi-homing seller. By contrast, platforms need to lower the uniform fee on single-homing buyers in order to poach. A greater share of delivery cost on the buyer side increases both the seller and buyer fees, and thus increase the platform’s profit. Research Implications – A greater share of delivery cost on buyer's side yields two positive effects for platforms. Sellers with lower delivery cost burdens enjoy a greater surplus, but eventually see a higher fee by platforms. Buyers facing greater delivery costs realize platforms are more differentiated horizontally, which shows inelastic demand for the fee, which brings less competition between platforms.

Increasing attention is being paid to the pricing decisions of ride-hailing platforms. These platforms usually face market demand fluctuation and reflect supply and demand imbalances. Unlike existing studies, we focus on the optimal dynamic pricing of the platforms under imbalance between supply and demand caused by market fluctuation. Dynamic models are constructed based on the state change of supply and demand by using optimal control theory, with the aim of maximizing the platform’s total profit. We obtain the optimal trajectories of price, supply, and demand under three ride demand situations. The effects of some key parameters on pricing decisions, such as coefficient of demand fluctuation, service quality, and fixed commission rate, are examined. We find the optimal dynamic price can improve the match of supply-demand in ride-hailing market and enhance the revenue of platform.

Among numerous capabilities, social media platforms have also enabled users to remix and repurpose analog videos through their features. This remediated media is further propelled by the platforms’ algorithmic systems, thus enhancing their visibility among users who, as affective publics, can interact with it and further remediate it. This paper discusses how the nostalgic discourse takes shape on Instagram and TikTok around remediated analog videos of parties and celebrations during the 1990s in Romania and how the platform affordances and the algorithmic imaginary of the affective publics influence the nostalgic discourse. The exploratory study utilizes a mixed method – combining digital ethnography, discourse analysis, and digital humanities – the research identifies a double-folded nostalgia, which is impacted by the interplay between each platform’s specific affordances and the imagined rules and styles of the platforms, imagined by their users.

The current competition law framework in Malaysia is found in the Competition Act 2010 and Competition Commission Act 2010, supplemented by various Malaysia Competition Commission Guidelines. An analysis of the e-commerce platforms market would demonstrate the creation of complex conglomerate ecosystems surrounding a few incumbent platforms that are resistant to conventional monocentric competition laws and policies focusing on price. Consumer complaints suggest the presence of unfair, exclusionary, and exploitative practices that affect various parties in the multi-sided e-commerce platforms that depend on the platform's infrastructure. This research seeks to identify the e-commerce platforms market ecosystem in Malaysia and analyse the regulatory framework governing market competition and safeguarding consumer protection in the e-commerce platforms market in Malaysia with references to notable competition cases and trending consumer complaints. Crucially, it aims to compare the Malaysian competition laws and policies against the Digital Markets Act and the Digital Services Act of the European Union in the context of the digital market, and employs doctrinal research, wherein the primary data is obtained through systematic content analysis of relevant reports and articles. Malaysian competition laws and policies have potential weaknesses that can be strengthened to safeguard consumer protection in the e-commerce platforms market. Article Details How to Cite

The article deals with the constitutional understanding of the place modern Internet platforms play in ensuring human rights. Some problematic aspects of the topic are illustrated through the lens of Russian and foreign legal practice, which has developed in connection with the functioning of wellknown digital platforms and promotion of information rights, digital security and privacy rights, freedom of speech within the boundaries of popular social networks, video hosting platforms, online services. Particular attention is paid to the analysis of the latest novelties of Russian legislation aimed at regulating the status and new grounds for responsibility of digital platforms. The cornerstone question proposed by the author for discussion is the question of the best model of interaction between the state and digital platforms, as well as the conditions and limits of their responsibility for violations of human rights. The article analyzes the problem of inconsistency of terms of services with generally recognized standards of international human rights law, examines options for unifying the platform’s policies in relation to the content published on them, examines the phenomenon of “refusal of constitutional rights by contract”. Taking into account the deduced features of digital platforms as a space for the realization of human rights, the author’s view of the system of legal measures aimed at improving the standards of protecting human rights on digital platforms, is proposed as conclusions.

This paper serves as an introduction to a symposium on the role that California oil and gas platforms serve as habitats for fishes and invertebrates. As of 2019, there are 27 platforms in state and federal waters off California, and the decommissioning of some of these platforms is imminent. Thus, consideration of whether to completely remove a platform or cut it off at some depth below the sea surface and retain the submerged portion as a reef is a decision that will occur in the near future. The objectives of the 10 papers in this dedicated issue of the Bulletin of Marine Science are to: (1) increase scientific understanding of the inter- and intrarelationships of fish and invertebrate populations at offshore oil and gas platforms and natural reefs within the Southern California Bight; (2) determine the extent of influence of platform assemblages on southern California and the Pacific coast populations of fishes and invertebrates; and (3) synthesize relevant reports, existing peer-reviewed literature, and new data analyses into a single peer-reviewed reference. This introductory paper contains a synopsis of all extant California platforms including information on: (1) the original operator, (2) the current operator of records, (3) the date the platform was installed, (4) the first production date, (5) the platform's distance from shore [including whether it is state or outer continental shelf (OCS) waters], (6) the bottom depth of the platform, (7) the number of well slots, (8) the number of conductors, (9) what the platform produces (oil and/or gas), (10) the platform jacket dimensions [generally at the seafloor (bottom)], (11) the platform's footprint, (12) the midwater surface area, (13) the total removal weight, (14) the platform location, (15) the shell mound size, (16) the shell mound volume, (17) the shell mound height, (18) the center of the shell mound location, and (19) the bottom slope. In addition, we present an overview of all previous research on the biology and ecology of California platform organisms.

Dalijimosi ekonomika (literatūroje dar vadinama – „bendro vartojimo ekonomika“) – tai verslo modelis, pagal kurį privatūs asmenys internetinių bendradarbiavimo platformų sukurtose atvirose rinkose dalijasi daiktais arba paslaugomis2, mažinant tapačių sandorių su tradicinėmis įmonėmis kaštus.3 Dalijimosi ekonomikos staigus augimas sukūrė prielaidas kilti konkurencijai įvairiose verslo šakose, tokiose kaip transportas, maisto pramonė, daiktų nuoma, pinigų skolinimas ir kt. Šiuo straipsniu nagrinėjamas dalijimosi ekonomikos poveikis tradicinei taksi paslaugų rinkai, didelį dėmesį skiriant „Uber“ platformai, kuri šiuo metu pavežėjimo srityje lyderiauja visame pasaulyje. Taip pat straipsniu siekiama išsiaiškinti, ar pavežėjimo platformos bei jų naudotojai nesąžiningai konkuruoja su taksi įmonėmis bei kokią įtaką dalijimosi platformoms ir jų veiklai daro teisinis reglamentavimas ir / ar jo stoka. Tikslui pasiekti aptariama dalijimosi ekonomikos, nesąžiningos konkurencijos ir pavežėjimo paslaugos samprata, teisinis reguliavimas bei teismų praktika Lietuvoje bei užsienio valstybėse. Juos įvertinus, nustatyta, kad tiek Lietuvoje, tiek kitose pasaulio valstybėse tradicinio taksi – keleivių vežimo – verslui dėl teisinio reguliavimo ir veiklos priežiūros stokos yra sudėtinga konkuruoti su dalijimosi platformomis. Tai kliudo tradicinėms įmonėms lygiomis teisėmis vykdyti savo veiklą, varžantis su dalijimosi ekonomikos dalyviais. Nors pavežėjimo paslaugas teikiantys asmenys daugeliu atveju privalo turėti licencijas ar leidimus kaip ir taksi paslaugas teikiančių įmonių vairuotojai, iki šiol nėra išvystyto patikros mechanizmo, kas užtikrintų viešojo intereso apsaugą. Dalijimosi platformos neužkerta kelio sukčiavimui, t. y. paslaugų teikimui naudojantis kito asmens leidimu ar licencija, taip neužtikrinant paslaugų teikėjų patikimumo. Be to, dalijimosi platformos paprastai savo civilinę atsakomybę apriboja minimalia pinigų suma ir neatsako už žalą, kilusią dėl paslaugos teikėjų neteisėtų veiksmų. Nustatyta ir tai, kad nors įvairiose pasaulio šalyse pavežėjimo platformos yra pripažintos transporto paslaugas teikiančiomis įmonėmis, o vairuotojai – jų darbuotojais, platformos neužtikrina visų darbuotojų teisių, kas privalu taksi paslaugas teikiančioms įmonėms. Įvertinus visus šiuos pavežėjimo paslaugas siūlančių platformų ir taksi paslaugas teikiančių įmonių skirtumus, svarbu atkreipti dėmesį ir į tai, kad ekonominiu požiūriu dalijimosi platformoms yra žymiai lengviau padidinti paslaugų pasiūlą. Tam, kad padidinti taksi skaičių, įmonė turi nupirkti automobilį, įdarbinti naują vairuotoją, užtikrinti, kad jis turėtų visus reikalingus dokumentus ir kt., o „Uber“ platformoje vairuotojų skaičius padidėja naujiems platformos naudotojams užsiregistravus platformoje ir pradėjus teikti paslaugas. Taigi, nors teisinis reguliavimas tikrose srityse keičiamas ir griežtina dalijimosi ekonomikos dalyvių veiklą, taisyklių trūkumas – vis dar akivaizdus. Taip pat trūksta efektyviai veikiančio priežiūros mechanizmo dėl asmenų licencijų, vartotojų teisių užtikrinimo ir kt. Manytina, kad tobulinant teisinį reguliavimą, turėtų būti apsvarstyta galimybė nustatyti dalijimosi platformų atsakomybę dėl vartotojų teisių pažeidimų, paslaugos kokybės užtikrinimo, taip ginant viešąjį interesą ir užtikrinant tinkamos paslaugos pasiekiamumą visuomenei.

Public Key Cryptography enables entity authentication protocols based on a platform's knowledge of other platforms' public key. This is particularly advantageous for embedded systems, such as FPGA platforms, with limited or none read-protected memory resources. For access control systems, an access token is authenticated by the mobile system. Only the public key of authorized tokens needs to be stored inside the mobile platform. At some point during the platform's lifetime, these might need to be updated in the field due to loss or damage of tokens. This paper proposes a holistic approach for an automotive access control system based on Public Key Cryptography. Next to a FPGA-based hardware architecture, we focus on a secure scheme for key flashing of public keys to highly mobile systems. The main goal of the proposed scheme is the minimization of online dependencies to Trusted Third Parties, Certification Authorities, or the like, to enable key flashing in remote locations with only minor technical infrastructure. Introducing trusted mediator devices, new tokens can be authorized and later their public key can be flashed into a mobile system on demand.

It is standard for blockchain platforms to issue native tokens, or crytpocurrencies, that users must own to operate within the platform. Some blockchains, however, decided to issue two tokens, establishing a dual system, with one token typically for governance and the other for implementing functions on the blockchain, such as executing transactions or smart contracts. Therefore, the two tokens are used for different activities. Typically, owning the governance tokens gives the right to receive the other token for free, as a reward for participating in the blockchain decision-making and voting processes. However, both tokens can also be traded on some exchange nodes, which means that platform functions could be implemented even without owning governance tokens. In this paper, we discuss some economic fundamentals of dual-token blockchain platforms—in particular, how to establish their economic value and the market relative attractiveness of the two tokens. We do so by introducing some simple numerical indicators, based on prices, and traded circulating monetary quantities. Such indicators, which are meant to reflect the platform’s view on the tokens’ market desirability, could be computed in real time and used to support the platform’s policy making.

Online retail platforms such as Amazon and Tmall have the ability to create personalized recommendations based on the consumer’s browsing history, purchase history, and preferences by investing in data analytics capability. In practice, manufacturers may encroach on the retail market through the agency channel that sells products directly to online consumers in addition to wholesale products to retail platforms through the reselling channel. In this study, we develop a game-theoretic model to study the interplay between the manufacturer’s encroachment and the online retail platform’s data analytics capability investment. Our outcomes reveal that the conditions for the manufacturer to encroach become more lenient if the platform invests in data analytics capability, and we show that the investment in data analytics capability can lead to a Pareto improvement and the manufacturer can free ride on the platform’s investment. Moreover, we found that the manufacturer’s encroachment always creates more incentives for the platform to enhance the investment level in data analytics capability. Our research in this study provides useful insights for managers to make encroachment decisions and data analytics capability investment decisions with the manufacturer who sells through the online retail platform.

<p>The rapid adoption of digital technology has revolutionized various industries, including the financial services sector, through the emergence of financial technology (Fintech). In Indonesia, Fintech regulations, such as Indonesian bank (Bank Indonesia-BI) regulations no. 18/40/PBI/2016 has played a crucial role in governing payment systems. This research examines the impact of the Fintech platform's effectiveness on individuals' interest in making infaq and sadaqah payments. A survey method was employed, utilizing a sample size of 128 individuals residing in the Solo Raya area, and conducted via Google form. The study results indicate that the Fintech platform's effectiveness significantly influences individuals' interest in making infaq or sadaqah payments. This can be attributed to the trust people place in Fintech platforms, which ensures data confidentiality and minimizes the risk of fraud. Consequently, individuals are more inclined to engage in infaq and sadaqah payments, recognizing Fintech platforms' secure and reliable nature. This research highlights the positive relationship between Fintech platform effectiveness and individuals' interest in infaq and sadaqah payments, shedding light on the potential for Fintech to drive the development of the Islamic economy further.</p>
