Short supply chains: Frameworks and extensions to public procurement

Recently, policymakers’ interest in short supply chains (SSCs), i.e., removing the non-value-adding intermediaries in the supply chain, has increased as these are seen as a means of supporting employment and sustainability goals. This article aims to elaborate on the understanding of SSCs, identify what motivates participants to get involved, examine their replicability in different sectors of the economy other than the food sector and how they can be fostered through public procurement. Policymakers’ objectives with public procurement align with those associated with SSCs; therefore, transferability may be possible in the context of public procurement, in addition to sustainability, and access to opportunities for SMEs. Semi-structured exploratory interviews were conducted with SSC stakeholders to examine this and conclude that SSCs can be a valuable means of conducting socially responsible public procurement, with mixed views about their ability to foster gender equality. A case study is also presented with the key message that the application of SSC should consider suppliers’ capabilities in addition to the mandatory application of SSC in the tendering process. Achieving positive results will require a shift in traditional procurement logic towards more flexible forms of co-opetition.

Understanding the evolution of competing institutional logics in the marketization of care: A stage model analysis of Australia's National Disability Insurance Scheme

This study explores the marketization of healthcare through a stage model analysis, focusing on Australia's National Disability Insurance Scheme (NDIS). By employing mixed methods, including sentiment and frequency analysis as well as qualitative content analysis of policy documents and media coverage, we trace the NDIS's evolution and the interplay of competing social welfare and market logics over time. Our findings underline that the evolution and interplay between competing institutional logics follow a stage model of institutional change, detailing pre-emergence, orientation, contestation, consolidation, and normalization phases. Additionally, we observe a shift in dominant institutional logics across different stages, demonstrating the critical role of media and public sentiment in shaping discourse about the marketization of care, which intertwines with policy decision-making. Our findings emphasize the importance of adaptive engagement and communication strategies by policymakers to avoid marginalizing vulnerable groups as institutional logics evolve, especially in the latter stages of the process when a dominant logic has emerged. The study highlights the complex dynamics of institutional change and offers insights for both researchers and practitioners in the healthcare sector, shedding light on the coevolution of competing logics in the policy development and implementation process.

The fiction of identity: veridiction and the contract of attention in the Netflix show Clickbait

The article utilises the analysis of the Netflix show Clickbait to explore cultural shifts in the standard logic of veridiction, which seem to break with the Greimasian model of veridictory modalities to welcome diverse procedures –such as faire semblant and authentication– governing the communication and perception of truth. Rather than a problem affecting only discourses, I aim to argue that the production of subjective identities, both in the physical world and mediated contexts, is also impacted by this change in our relationship with signs. By presenting a dialogue between theories concerned with traditional and emerging mechanisms related to veridiction, the article offers a reflection on the production and deployment of identity, and the blurring of lines between reality, unreality, and fiction, which produces simulacral dynamics shifting the goal of interactions from a sanction- to an attention-oriented model.

Catalytic Enantioselective Hydroxylation of Tertiary Propargylic C(sp3)-H Bonds in Acyclic Systems: a Kinetic Resolution Study.

Direct site-selective and enantioselective oxyfunctionalization of C(sp3)-H bonds to form alcohols with a general scope, with predictable selectivities, and in preparatively useful yields represents a paradigm shift in the standard logic of synthetic organic chemistry. However, the knowledge of either enzymatic or nonenzymatic asymmetric hydroxylation of tertiary C-H bonds for enantioenriched tertiary alcohol synthesis is sorely lacking. Here, we report a practical manganese-catalyzed enantio-differentiating hydroxylation of tertiary propargylic C-H bonds in acyclic systems, producing a wide range of structurally diverse enantioenriched tertiary propargyl alcohols in high efficiency with extremely efficient chemo- and enantio-discrimination. Other features include the use of C-H substrates as the limiting reagent, noteworthy functional group compatibility, great synthetic utilities, and scalability. The findings serve as a blueprint for the development of metal-catalyzed asymmetric oxidation of challenging substrates.

Lightweight Image Encryption Using a Novel Chaotic Technique for the Safe Internet of Things

Recently, the field of lightweight cryptography (LWC) has emerged in response to the security needs of low-cost, widely used technology. It is essential to implement an encryption approach with access control to give less complex, more flexible, and safe access to sensitive data. In this work, a novel lightweight chaotic encryption approach with fuzzy access control is presented to encrypt light images in the IoT domain, while maintaining image quality. With the aid of multiplexer modeling and information shift register technology, the algorithm’s design combines random and chaotic mapping approach based on a specific password key with a predetermined number of fuzzy logic shifts on the password key for the image pixels. Further, to extract the private key with complexity and boost defense against attacks, a shift register and logical xor combination is employed. The simulation of the proposed model for AVR microcontroller has been done under MATLAB software and the design of various encryption components has been used to implement lightweight mapping. The proposed system has been evaluated in terms of histogram analysis, adjacent pixel correlation analysis, contrast analysis, homogeneity analysis, energy analysis, NIST analysis, error mean square analysis, information entropy, pixel number change rate, integrated mean change intensity, peak signal-to-noise ratio, and time complexity. Remarkably, the proposed technique has demonstrated high efficiency. The simulation results show that the homogeneity, energy, contrast, NPCR, and UACI criteria have improved by 11.5%, 13.1%, 19%, 0.53%, and 0.12%, respectively, compared to other methods in other articles.

QM-DLA: an efficient qubit mapping method based on dynamic look-ahead strategy

Quantum computing has already demonstrated great computational potential across multiple domains and has received more and more attention. However, due to the connectivity limitations of Noisy Intermediate-Scale Quantum (NISQ) devices, most of the quantum algorithms cannot be directly executed without the help of inserting SWAP gates. Nevertheless, more SWAP gates lead to a longer execution time and, inevitably, lower fidelity of the algorithm. To this end, this paper proposes an optimized qubit mapping algorithm based on a dynamic look-ahead strategy to minimize the number of SWAP gates inserted. Firstly, a heuristic algorithm is proposed based on maximizing physical qubit connectivity to generate the optimal initial qubit mapping, which reduces the need for logical qubit shifts during subsequent SWAP gate insertion. Secondly, in the form of directed acyclic graphs, we identify quantum gates that violate the constraints of physical coupling and insert SWAP gates to remap qubits, thereby overcoming the limitations of qubit interactions. Finally, the optimal SWAP gate insertion strategy is built by comparing the cost of different SWAP gate insertion strategies through a multi-window look-ahead strategy to reduce the number of SWAP gates inserted. The experimental results show that the strategy in this paper decreases the number of SWAP gate insertions and significantly reduces the depth of quantum circuits when performing qubit mapping compared with state-of-the-art methods.

Metadisciplinarity at the intersection of modern philosophical and philological practices

The article explores the relationship between inter-, trans-, and polydisciplinarity in contemporary humanities. It highlights philosophy's role in fostering critical thinking and methodological reflection. The phenomenon of intersubjectivity/interculturality is discussed in today's network society, emphasizing the ongoing exchange between individual consciousness and interpersonal perception within metadisciplinary philosophical studies. The article illustrates the practical application of metadisciplinarity through a PhD program at Kyiv National Linguistics University, advocating for the reintroduction of philosophy into modern education. It proposes an interdisciplinary segment, "Philosophy of Science and Methodology of Humanitarian Knowledge," integrating philological and professional teaching with philosophy to cultivate reflective and critical skills. The program aims to equip postgraduate students with knowledge of logical, methodological, and epistemological shifts, applicable in teaching. Ultimately, it asserts that combining specific scientific knowledge with philosophical principles in education shapes a flexible and deep conceptual framework, enhancing modern scientific and philosophical discourse. This multimodal approach to metadisciplinary philosophy fosters innovative paradigmatic trends.

Parallel Accelerating Number Theoretic Transform for Bootstrapping on a Graphics Processing Unit

The bootstrapping procedure has become the main bottleneck affecting the efficiency of all known fully homomorphic encryption (FHE) schemes. The state-of-the-art scheme for efficient bootstrapping, which is called fully homomorphic encryption over the torus (TFHE), accelerates polynomial multiplication by leveraging number theoretic transform (NTT) and implementing NTT in parallel on a GPU. Unfortunately, almost none of the recent advancements in NTT take full advantage of a GPU, leading to the need for more time. With this in mind, in this work, a novel faster number theoretic transform based on a GPU is proposed, in which matrix multiplication is used to implement a decomposed small-point NTT. When implementing matrix multiplication, we introduce a merging preprocessing method to merge multiple inputs of the small-point NTT, aiming to effectively minimize the count of modulo operations. Subsequently, when the merged result is multiplied by rotation factors, we use logical left shift rather than arithmetic multiplication to improve the computational efficiency. Our scheme can easily be used to realize a 1024-point NTT and the results of the experiments show that the speedup ratio of our method over the butterfly algorithm is about 2.49.

Metaorganizing Collaborative Innovation for Action on Grand Challenges

Grand Challenges are complex issues that require collaborative innovation among heterogeneous actors who draw upon contradictory institutional logics. While existing literature shows how social enterprises and individual organizations reconcile tensions between economic and environmental logics, scholars know less about how and when a broad set of actors adopt practices and priorities that balance economic and environmental values. This article explores how three agricultural cooperatives act as metaorganizations and facilitate collaborative innovation and sustainable transitions to address grand challenges regarding land use. We find that the cooperatives stimulate awareness of environmental challenges and local experimentation, orchestrate collaborative solutions by enrolling and engaging a broad set of actors, and coordinate the diffusion of novel practices across the institutional field. We add new insights into producer cooperatives' role as metaorganizations in facilitating the creation, validation, and diffusion of practices that balance business and sustainability. Based on our findings, we argue that by metaorganizing, producer cooperatives can galvanize field-level shifts in institutional logics through framing, knowledge sharing, and knowledge brokering mechanisms.

The de-perimeterisation of information security: The Jericho Forum, zero trust, and narrativity.

This article analyses the transformation of information security induced by the Jericho Forum, a group of security professionals who argued for a new 'de-perimeterised' security model. Having focused on defensive perimeters around networks, early 2000s information security faced a growing set of pressures: the maintainability of firewalls given increasing traffic volume and variety, the vulnerability of interior network domains, and the need to cope with and enable new working arrangements and ways of doing business. De-perimeterisation was a radical rethinking of the nature of security and created the conditions for the rise of 'Zero Trust' architectures. This shift has radical implications for the architectures of digital infrastructures that undergird many aspects of contemporary life, the risks to which people and societies are exposed, and the nature of work and business in a digital economy. We develop a semiotic analysis of the Jericho Forum's interventions. Using insights from material semiotics, security theory and the theory of narrativity, we argue that de-perimeterisation can be understood as a shift in security logic, or, a shift in how security can (be made to) make sense. We examine a cluster of images used by the Jericho Forum, and analyse how they challenged the coherence of perimeter-based thinking and provided the materials for constructing a new model. We argue that a focus on the narrative dimension of security provides a window into fundamental semantic transformations, reciprocal historical relations between semantics and technical change, the agencement of security technologies, and determinations of value (what is worth securing).

How do changing institutional logics affect innovation? The cases of Online Electric Vehicle and Fuel Cell Electric Vehicle in Korea

ABSTRACT The coevolution of technological capabilities and institutional arrangements is critical for the success of innovations. Yet, it remains unclear how actors’ shifting relations during institutional change affect innovation. The paper examines the dynamics in how actors shape the institution by integrating the institutional logics perspective with policy mix literature. Insights are drawn from the Online Electric Vehicle and Fuel Cell Electric Vehicle cases in Korea, where involved stakeholders revealed contrasting identities and practices throughout the innovation stages. While both cases witnessed shifts in institutional logics, the repercussions on innovation differed depending on the characteristics of actors’ identity mix. Findings contribute to institutional theory by expanding the traditional dyadic perspective on incumbent and emerging institutional logics. We also add to the policy mix literature by introducing a neo-institutional perspective. The paper concludes by underlining how the overarching characteristics of the institutional mix trigger different coordination failures.

Atroposelective hydroarylation of biaryl phosphines directed by phosphorus centres

Prized for their ability to generate chemical complexity rapidly, catalytic carbon–hydrogen (C–H) activation and functionalization reactions have enabled a paradigm shift in the standard logic of synthetic chemistry. Directing group strategies have been used extensively in C–H activation reactions to control regio- and enantioselectivity with transition metal catalysts. However, current methods rely heavily on coordination with nitrogen and/or oxygen atoms in molecules and have therefore been found to exhibit limited generality in asymmetric syntheses. Here, we report enantioselective C–H activation with unsaturated hydrocarbons directed by phosphorus centres to rapidly construct libraries of axially chiral phosphines through dynamic kinetic resolution. High reactivity and enantioselectivity are derived from modular assembly of an iridium catalyst with an endogenous phosphorus atom and an exogenous chiral phosphorus ligand, as confirmed by detailed experimental and computational studies. This reaction mode significantly expands the pool of enantiomerically enriched functional phosphines, some of which have shown excellent efficiency for asymmetric catalysis.

“We Will Die as Free People”

Research on the impact of COVID-19 on mobilization focuses extensively on the role of social media, conspiracy theories, and divisive narratives. However, individual perceptions remain insufficiently researched. This article argues that fantasmatic narratives are central to mobilization and aims to analyze changes in discourse during the pandemic as outcomes of shifts in fantasmatic logics. It applies the logics approach to the Lithuanian case to identify the main changes in fantasmatic logics of discourse that became apparent in response to government action. The article analyzes data from social media posts, gathered over a period of two months (June–August 2021), the period centered around the announcement of the “quarantine of the unvaccinated.” The analysis revealed significant changes in fantasmatic logics of discourse—the Other was no longer seen as corrupt for their own gain by the protesters, but as purely evil, which in turn led to openness to various conspiracy theories.

Exploring the impact of initial design techniques on area, timing, and power in technology mapped designs: A case study on 32-bit arithmetic logic unit

This research paper investigates the influence of different initial design techniques on the area, timing, and power aspects of technology-mapped designs. As a practical case study, we undertake the design and analysis of a 32-bit arithmetic logic unit (ALU) utilizing two distinct adder approaches. The ALU, a fundamental component of all processors, comprises three major units: the Adder responsible for signed and unsigned number addition and subtraction, the Logic unit which handles bitwise logical operations, and the Shifter unit facilitates arithmetic and logical shift operations. The two adder designs are based on the ripple carry method (ALU_RCA) and the Sklansky method (ALU_SKL), respectively. The design and analysis process involved utilizing established toolsets from Cadence, including NCSIM for simulation and verification, RTL Compiler for logic synthesis, static timing analysis and power estimation, and SOC encounter tool for floorplanning and layout. Through this investigation, we aim to shed light on the varying performance implications of different initial design approaches in technology-mapped designs.

Analog/digital circuit simplification for Hopfield neural network

Circuit realization of neural networks is a significant approach in neuromorphic computing. Researchers have simplified the circuit for single neuron model, but one for neural network is rarely reported, yet. This paper presents a ReLU-type Hopfield neural network (RHNN) model using simple ReLU function instead of traditional hyperbolic-type function as the activation function. RHNN with three neurons is focused on. Its boundedness and stability are confirmed theoretically, and complex chaotic dynamics are simulated numerically. Further, the printed circuit board (PCB)-based analog circuit is fabricated, and the RHNN circuit has 49.3 % fewer analog components than the Tanh-type HNN circuit. Meanwhile, with logical shift method, an efficient low-cost multiplierless digital circuit is developed on field-programmable gate array (FPGA) platform. Experimental results manifest that resource consumptions of one are less than that of IP core-based digital implementation. Particularly, the RHNN model is well applied to image encryption for satisfying requirements on transmission security.

“Money is not an issue!”: Hospital CFOs’ narratives about handling a sudden shift in managerial focus

The sustained political and managerial focus on cost containment and efficiency in hospitals has been altered by COVID-19-related concerns about public health. Through a novel qualitative study in Denmark, we explore CFOs’ narratives of their experiences during a sudden shift in managerial logic. All of the CFOs describe engagement in key operational procedures and change management that was fostered by the constant search for stability that strongly depended on bottom-up decision-making and flexibility. During this process, the existing competing logics of managerialism and medical professionalism vanished. The CFOs describe new forms of dynamic and collaborative approaches. The possibility of adhering to the core logic of administrative accounting techniques combined with urgency and emotional encounters appears to enable this approach. Thus, we document a moment when well-known opposing logics were suspended by exogenous urgency. This finding suggests possibilities for moving beyond deep-rooted views on established public administration structures and logics. Points for practitioners Financial managers show administrative skills that are useful for public administration changes in both administration and daily operations. These managers appear to have a strong core identity and willingness to dynamically engage with and facilitate acute frontline operational issues. In an emergency situation such as COVID-19, we find co-dependency across subject fields (administration and medical professions) which enables collaborations.

Logical coupling and paradigm shift of regional cultures in terms of “the belt and road initiative” —— A case study of lingnan culture

Regional culture plays an important role in the dissemination of culture along “the Belt and Road Initiative”, and through the efficient application, layout and flow of cultural resources, it can achieve industrial and economic efficiency. Cultural exchanges and interflow are raised and recommended by “the Belt and Road Initiative”. From the three dimensions of history, reality and development, the paradigm shift of regional culture in the context of “the Belt and Road Initiative”cultural development must be based on a historical and developmental perspective, with heritage and innovation as the body, and contemporary values to reflect on the problems in cultural development, so as to achieve the integration of unity and pluralism, and to provide a strong impetus for the cultural development of “the Belt and Road Initiative”.

Photoluminescent Janus oxazolidine nanoparticles for development of organic light-emitting diodes, anticounterfeiting, information encryption, and optical detection of scratch.

Photoluminescent polymer nanoparticles based on organic compounds are a new category of advanced materials with potential applications in various fields such as chemosensors, optical devices, drug-delivery systems, anticounterfeiting inks and bioimaging. Herein, amide functionalized copolymer nanoparticles with a particle size in the range of 42-139nm were synthesized by emulsion copolymerization of methylmathacrylate (MMA) and methacrylamide (MAAm) with different concentrations in the range of 0-20wt%. Afterward, the photoluminescent copolymer nanoparticles (PLCNPs) were prepared by physical modification of amide functionalized copolymer nanoparticles with 5wt% of oxazolidine derivative (OXOH). Investigation of optical properties include of photoluminescence and UV-vis spectra displayed significant dependency of emission and absorbance bands to the local polarity or the concentration of the amide groups on the surface of the nanoparticles. Study of Commission Internationale de l'Eclairage (CIE) colorimetric diagrams for PLCNPs samples confirmed the results of photoluminescence and UV-vis spectra, which a logical shift in color of the photoluminescence emission was observed by an increase in the concentration of the amide groups. The PLCNPs samples have remarkable stability (in physical and optical properties) when applied on polar substrates such as polymer sheet and cellulose paper. Therefore, the PLCNPs samples were used for development of eco-friendly water based anticounterfeiting inks, photoluminescence organic light emitting diodes (OLEDs), and also the photodetection of scratches in a fast and facile manner. The printed security tags and hand-written phrases on cellulosic papers have orange fluorescent emission with maximum intensity because nanoscale size of particles, which reduced the light scattering and increased the accessible concentration of OXOH for light absorption. A coating of poly(vinyl alcohol) (PVA)/PLCNPs solution onto a blue LED (365nm) was led to a change in the color of emission from blue to purple, because of the excitation of OXOH molecules at 365nm with the subsequent emission of purple light. The photodetection of created scratch on polycarbonate sheet was carried out by spray of PLCNPs solution on sheet and then illumination with UV irradiation (365nm). Developed water based PLCNPs samples have interesting optical properties, high stability on different surfaces and nanoscale particle size which are applicable in multiple applications such as eco-friendly photoluminescent inks for anticounterfeiting technologies, photoluminescence OLEDs, and also optical detector for monitoring of scratches on different substrates.

Videogames-as-a-service: How does in-game value co-creation enhance premium gaming co-creation experience for players?

The games as a service model have enabled game developers to reach worldwide audiences and regard games as services rather than products, opening up new avenues to establish value propositions. Freemium–premium gaming models of value co-creation have been studied in the past. Fostering the conversion of free users to premium subscribers and retaining those premium users are critical objectives for premium service providers. It is critical to effectively enable value co-creation through appropriate value propositions when the logic shifts from products to services such as depicted in the service-dominant logic. Since value propositions are the cornerstone of value, they must include insights about the customer's preferences, capabilities, and expectations, which can be gathered through the customer's value co-creation activities. Furthermore, little is known about the value realization that is assessed after using premium gaming services. The current study, which builds on the conceptual foundations of S-D logic, intends to investigate the gaming players' in-game co-creation experiences in the premium gaming setting through value co-creation activities. The model was tested using structural equation modeling (SEM)-based partial least based on survey data collected from 346 online gamers who used in-game premium services. The findings indicate that superior functionality, competition, sociability, personalization, and self-indulgence all have a substantial impact on players' desire to co-create with gaming service providers. Furthermore, the data revealed a significant outcome of value realization, which is appraised based on the premium gaming players' co-creation experience aspects. The findings of study 1 were further validated through qualitative intuitions to ensure the robustness of the valuable key insights, which confirms that different premium gaming motivations are necessary to enhance the value co-creation ties and gamer's overall co-creation experience positively. To improve premium players' co-creation experiences, online game service providers should route co-creation media into premium gaming settings.

Circular Moonshot: Understanding Shifts in Organizational Field Logics and Business Model Innovation

We aim to understand how actors respond to field logic plurality and maintain legitimacy through business model innovation. Drawing on a longitudinal field study in the fashion industry, we traced how de novo and incumbent firms incorporate circular logics in business models (for sustainability) and uncover how the intersection between issue and exchange fields creates institutional complexity and experimental spaces for business model innovation. Our findings showed a shift in the discourse on circular logic that diverted attention and resources from materials innovation (e.g., recycling) to business model innovation (e.g., circular business models). By juxtaposing institutional complexity and external pressure to maintain legitimacy, we derived four strategic business model innovation responses—preserve, detach, integrate and extend—that illuminate how actors leverage shifting logics and innovate extant business models (for sustainability). We make novel contributions to the literature on organizational fields, business models for sustainability, and business model innovation.
