Chain quality information management: development of a reference model for quality information requirements in pork chains
Authors: Althoff Gereon , Ellebrecht Alexander , Petersen Brigitte 
Published: September 2008

As in many food chains, pork production is carried out in heterogeneous chain scenarios with diverse organisational arrangements. Inter-organisational information management systems have not yet been established in pork production even though they provide a chance to improve chain-wide cooperation and quality management. This article presents the concept and first results of a sub-project in an ongoing Dutch-German collaborative research and development project of the public-private network "GIQS e.V." that develops tools for improved quality and health management in pork chains. In this sub-project a chain quality information system was designed, implemented and validated in three pilot chains in Germany and the Netherlands. The major result is a comprehensive implementation guideline for chains that want to improve their use of chain quality information in their quality and health management. The aim of this study was to identify chain actors' information requirements, taking into account the existing organisational heterogeneity in the pork industry. The theoretical framework of this paper integrates the netchain model with the process approach of ISO 9000:2000. The focus lies on describing a general structure of a chain-wide information system. The concept of inter-enterprise data warehousing is adopted for quality management in food chains. Based on this concept, a "natural language" reference model for information requirements in pork netchains was generated. The reference model was adapted to three separate pilot chains. This paper presents the results obtained by implementing the model in one of the pilot chains, with a special focus on improving animal health management and supporting risk-based meat inspection with chain-wide information management.
Strategies for collaboration in new product development
Authors: Mark-Herbert Cecilia 
Published: September 2008

In the past decades Swedish food companies have faced increasing competition. One way of gaining competitive advantage is to find new ways of creating added value based on technological development. This may lead to the production of valueadded products, profits from licensing agreements and a boost for the company image. Businesses that want to succeed in this market also need to develop new managerial methods, in particular in identifying critical technologies and strategic collaboration partners. The presented case studies provide examples of building internal skills, employing innovative external sourcing, developing new markets with strong brands and establishing networks and alliances for new product development.
Transparency in food supply chains: empirical results from German pig and dairy production
Authors: Deimel Mark , Frentrup Mechthild , Theuvsen Ludwig 
Published: September 2008

Abstract
Food supply chains have been faced with increasing requirements for transparency in recent years. However, evaluating the status quo of transparency of netchains entails measurement problems, since transparency is a multifaceted phenomenon as well as a latent variable. In this paper we present a measurement model that integrates various perspectives on transparency and, moreover, considers various measurement concepts. This model provides a theoretical basis for the empirical analysis of transparency in German pig and dairy production, which reveals interesting differences between the two sectors as perceived by farmers. The model and the empirical results deliver a more comprehensive understanding of the determinants and effects of various degrees of transparency in food supply chains.
Trust conditional on governance structure: theory and evidence from case studies
Authors: Fritz Melanie , Martino Gaetano , Surci Giulio 
Published: September 2008

Abstract
The paper proposes the idea that trust-based relationships can be established within the specific governance structures chosen by the agents. The theoretical background of this paper spans the literature from transaction cost and contract theory to supplier relationship management and trust theory. First communication and experience, risk perception attitude and the trade-off between trust and control are discussed within the analysis of trust source factors. Then these elements are considered in the light of Transaction Cost Economics. Three case studies are then presented in order to corroborate the theoretical proposition.
Can strategic alliances in food processing increase the technical efficiency of housewives groups in Thailand?
Authors: Nonthakot Phanin , Villano Renato , Fleming Euan 
Published: September 2008

Abstract
An assessment is made of the effects of strategic alliances, among other factors, on the performance of community-based food processing enterprises in the northern province of Thailand. Using survey data, we estimate a stochastic frontier production function and examine a number of factors affecting technical inefficiency of housewives groups focusing on the nature of strategic alliances. Our results show that vertical strategic alliances in marketing at the regional and provincial levels provide a means for housewives groups to increase productivity by attaining higher levels of technical efficiency through membership.
The use and significance of social capital and informal learning in postsecondary STEM education
Authors: Han Caleb Seung‐hyun , Chai Dae Seok 
Published: April 2024

AbstractDespite intense interest in how social capital can facilitate informal learning, few attempts have been made to synthesize the interface between social capital and informal learning. Social capital is an important factor in the application of informal learning, especially in postsecondary science, technology, engineering, and mathematics (STEM) education. This paper first presents a review of the literature that has explored the relationship between social capital and informal learning in STEM education. We then present two case studies illustrating how social capital plays a pivotal role in enhancing informal learning outcomes in postsecondary STEM education. These cases offer insights on how to promote optimal informal learning in STEM education. Implications for understanding the importance of social capital in informal learning are discussed.
Sterically Twisted Mitochondria‐Targeting Photosensitizers for Augmented Near‐Infrared II Fluorescence‐Guided Photodynamic Immunotherapy

Published: April 2024

AbstractNear‐infrared (NIR) fluorescent mitochondria‐targeting photosensitizers (PSs) hold great potential for efficient image‐guided cancer phototherapy, but it remains challenging to develop PSs concurrently integrating high‐contrast NIR‐II fluorescence imaging and efficient therapeutic capabilities. Herein, a heptamethine cyanine (HCy) PS (termed I2HCy‐TPE nanoparticles (NPs)) by a molecular engineering strategy combining the heavy atom effect and structural distortion is reported. The heavy atom iodine is introduced to boost the intersystem crossing process, and the bulky tetraphenylethylene (TPE) moiety placed at the meso‐position of the heptamethine chain creates a highly distorted conformation in I2HCy‐TPE, theoretically verified by density functional theory calculations. This strategy synergistically promotes the 1O2 generation efficiency and assure the strong NIR fluorescence emission in aggregated states. Combining with the intrinsic mitochondria‐targeting capability, I2HCy‐TPE NPs are able to cause mitochondria‐targeted damage of cancer cells via the PDT and immunogenetic cell death‐triggered immune responses under NIR laser irradiation. In vivo experiments demonstrate that the biocompatible I2HCy‐TPE NPs present exceptional capability for in vivo NIR‐II fluorescence bioimaging of whole‐body and blood vessels, and exert efficient NIR‐II fluorescence‐guided photodynamic immunotherapy against triple‐negative breast cancer.

AbstractExploring the nature of human intelligence and behavior is a longstanding pursuit in cognitive neuroscience, driven by the accumulation of knowledge, information, and data across various studies. However, achieving a unified and transparent interpretation of findings presents formidable challenges. In response, an explainable brain computing framework is proposed that employs the never‐ending learning paradigm, integrating evidence combination and fusion computing within a Knowledge‐Information‐Data (KID) architecture. The framework supports continuous brain cognition investigation, utilizing joint knowledge‐driven forward inference and data‐driven reverse inference, bolstered by the pre‐trained language modeling techniques and the human‐in‐the‐loop mechanisms. In particular, it incorporates internal evidence learning through multi‐task functional neuroimaging analyses and external evidence learning via topic modeling of published neuroimaging studies, all of which involve human interactions at different stages. Based on two case studies, the intricate uncertainty surrounding brain localization in human reasoning is revealed. The present study also highlights the potential of systematization to advance explainable brain computing, offering a finer‐grained understanding of brain activity patterns related to human intelligence.

AbstractIce has been suggested to have played a significant role in the origin of life partly owing to its ability to concentrate organic molecules and promote reaction efficiency. However, the techniques for studying organic molecules in ice are absorption‐based, which limits the sensitivity of measurements. Here we introduce an emission‐based method to study organic molecules in water ice: the phosphorescence displays high sensitivity depending on the hydration state of an organic salt probe, acridinium iodide (ADI). The designed ADI aqueous system exhibits phosphorescence that can be severely perturbed when the temperature is higher than 110 K at a concentration of the order of 10−5 M, indicating changes in hydration for ADI. Using the ADI phosphorescent probe, it is found that the microstructures of water ice, i.e., crystalline vs. glassy, can be strongly dictated by a trace amount (as low as 10−5 M) of water‐soluble organic molecules. Consistent with cryoSEM images and temperature‐dependent Raman spectral data, the ADI is dehydrated in more crystalline ice and hydrated in more glassy ice. The current investigation serves as a starting point for using more sensitive spectroscopic techniques for studying water‐organics interactions at a much lower concentration and wider temperature range.
Turtles for the ancestors: A zooarchaeological study of ritual deposits on Fakahina, Tuamotu archipelago (French Polynesia)

Published: April 2024

AbstractRituals and feasting ceremonies at Polynesianmaraedepict culturally complex relationships between humans and animals that cannot be explained by subsistence alone. In Central‐East Polynesia, this topic still requires the elaboration of a “ritual zooarchaeology” framework. Using sea turtle assemblages from three sacred sites on Fakahina atoll (Tuamotu), this study offers a preliminary approach to faunal deposits from ritual contexts. Following systematic excavations ofmaraeon Fakahina, analysis aimed to determine whether faunal deposits could be linked with intentional feasting and offering behaviours. To detect how ritual actions were organised through space, skeletal and taphonomic variables were examined for both overall sites and “sub‐assemblages” within sites based on the spatial associations of fauna with site features.At certain site features, derived quantitative units such as %MAU and recovery rate could identify potential offering behaviours through the intentional sorting of culturally significant body parts. The taphonomic signatures of site features could also identify open or closed deposition environments, assisting with the identification of disturbed features as either exposed platforms or enclosed cists. In addition to highlighting previously undocumented complexity in the use of site features, an overall comparison of turtle remains from the three sites shows the potential of these methods to explore variation in ritual practices.

AbstractUnderstanding the mechanisms underpinning the origins, patterns and dynamics of biodiversity is fundamental in biology and ecology. Trait‐based ecology emphasizes the importance of functional traits in community assembly and ecosystem properties, however, functional traits can also provide links with biodiversity at broader temporal and spatial scales. Here, we proposed a perspective of using functional traits to analyze and predict biodiversity from different ecological dimensions, along with the influences of evolution and environment. We summarized current research progress on roles of plant functional traits in species adaptation and coexistence, biodiversity‐ecosystem functioning, species distribution and global biodiversity, in order to integrate a functional approach to investigate biodiversity, and then discussed future trends of biodiversity studies under environmental change.

AbstractAmniotic membrane extract (AME) and Wharton's jelly mesenchymal stem cells derived‐exosomes (WJ‐MSC‐Exos) are promising therapeutic solutions explored for their potential in tissue engineering and regenerative medicine, particularly in skin and corneal wound healing applications. AME is an extract form of human amniotic membrane and known to contain a plethora of cytokines and growth factors, making it a highly attractive option for topical applications. Similarly, WJ‐MSC‐Exos have garnered significant interest for their wound healing properties. Although WJ‐MSC‐Exos and AME have been used separately for wound healing research, their combined synergistic effects have not been studied extensively. In this study, we evaluated the effects of both AME and WJ‐MSC‐Exos, individually and together, on the proliferation of corneal keratocytes as well as their ability to promote in vitro cell migration, wound healing, and their impact on cellular morphology. Our findings indicated that the presence of both exosomes (3 × 105 Exo/mL) and AME (50 μg/mL) synergistically enhance the proliferation of corneal keratocytes. Combined use of these solutions (3 × 105 Exo/mL + 50 μg/mL) increased cell proliferation compared to only 50 μg/mL AME treatment on day 3 (**** p < 0.0001). This mixture treatment (3 × 105 Exo/mL + 50 μg/mL) increased wound closure rate compared to isolated WJ‐MSC‐Exo treatment (3 × 105 Exo/mL) (*p < 0.05). Overall, corneal keratocytes treated with AME and WJ‐MSC‐Exo (3 × 105 Exo/mL + 50 μg/mL) mixture resulted in enhanced proliferation and wound healing tendency. Utilization of combined use of AME and WJ‐MSC‐Exo can pave the way for a promising foundation for corneal repair research.

Published: April 2024

AbstractThis study explores a combination of the concept of enantioselective enzymatic synthesis of β‐chiral amines through transamination with in situ product crystallization (ISPC) to overcome product inhibition. Using 2‐phenylpropanal as a readily available and easily racemizing substrate of choice, (R)‐β‐methylphenethylamine ((R)‐2‐phenylpropan‐1‐amine) concentrations of up to 250 mM and enantiomeric excesses of up to 99 % are achieved when using a commercially available transaminase from Ruegeria pomeroyi in a fed‐batch based dynamic kinetic resolution reaction on preparative scale. The source of substrate decomposition during the reaction is also investigated and the resulting unwanted byproduct formation is successfully reduced to insignificant levels.
Emerging Two–Dimensional Intercalation Pseudocapacitive Electrodes for Supercapacitors

Published: April 2024

AbstractThe growing need for efficient energy storage has spurred advancements in supercapacitors (SCs), aiming to offer high power and energy density simultaneously. While SCs offer longer cycles and higher power density values, their low energy densities limit practical applications. In response, pseudocapacitive materials have emerged, leveraging reversible Faradaic reactions at or near the surface for enhanced energy storage. This approach surpasses the constraints of the electrical double layer in SCs and the mass transfer constraints of batteries. Progress in asymmetric supercapacitors and high mass loading has improved energy density values, yet maintaining high mass loading without compromising power density remains a hurdle. Advancements in pseudocapacitance through intercalation during charging/discharging processes, especially in layered structures like graphite, graphene, transition metal oxides (TMOs) transition metal dichalcogenides (TMDCs), MXenes, and metal–organic frameworks (MOFs) have proven significant. The intercalated species induce reversible or irreversible structural changes, contributing to the physicochemical characteristics of the electrode materials. Exploring the intercalation mechanism in bulk two‐dimensional (2D) materials reveals distinct differences that enhance our understanding and improve electrochemical properties for superior energy storage. Finally, an in‐depth exploration of the intercalation pseudocapacitance in 2D materials such as TMDCs and MXenes underscores their significance, setting a benchmark for future electrochemical studies in the subsequent advancement of SCs research.

Published: April 2024

AbstractAddressing a long‐standing gap in the work‐life literature in identifying across‐domain implications of volunteering, this paper examines how individuals manage cross‐domain demands of work, life, and volunteering using twenty in‐depth interviews with young adults from Canada. Results revealed six distinct motivators for volunteering along the intrinsic‐extrinsic motivation spectrum, and the strategies adopted in managing the demands across the triple domains. Six categories align with the volunteer functional inventory (VFI), validating VFI and linking the functional analysis to motivation spectrum. The manuscript significantly adds to theory and practice by introducing the Matrix of Motivators and Resource Investment (MMRI), which identifies different volunteer types with the drivers for volunteering and resource prioritization. The study also highlights practical implications and future research directions.

SummaryCloud computing has attracted great interest in various scientific and technical fields recently as one of the widely adopted networking technologies. Despite their many benefits and applications, it still faces many security and trust challenges, including managing and controlling services, privacy, data integrity in distributed databases, data backup, and synchronization. Moreover, due to its centralized architecture, and lack of transparency and traceability, the results of the trust assessment cannot be fully recognized by all users. However, creating a trust‐based transaction environment has become its key factor. Blockchain, with its nature of decentralization and security, can be leveraged to address these challenges and build a distributed and decentralized trust architecture, due to the underlying characteristics such as transparency, traceability, decentralization, security, immutability, and automation. This article makes a comprehensive study of how blockchain is applied to deliver security services in the cloud computing model, focusing on up‐to‐date approaches, opportunities, and future directions. This survey also discusses the benefits of the technical fusion of blockchain and cloud. It provides a classification of proposed systems based on privacy, data sharing, authentication, and access control, as well as auditing and data integrity. Finally, the main conclusions of this study will be the challenges and future directions to stimulate further research in this promising field.

ABSTRACTObjectiveThe COVID‐19 pandemic had a profound negative impact on the psychological wellbeing of healthcare providers (HPs), but little is known about the factors that positively predict mental health of primary care staff during these dire situations.MethodsWe conducted an online questionnaire survey among 702 emergency department workers across 10 hospitals in Switzerland and Belgium following the first COVID‐19 wave in 2020, to explore their psychological vulnerability, perceived concerns, self‐reported impact and level of pandemic workplace preparedness. Participants included physicians, nurses, psychologists and nondirect care employees (administrative staff). We tested for predictors of psychological vulnerability through both an exploratory cross‐correlation with rigorous correction for multiple comparisons and model‐based path modelling.ResultsFindings showed that the self‐reported impact of COVID‐19 at work, concerns about contracting COVID‐19 at work, and a lack of personal protective equipment were strong positive predictors of Depression, Anxiety, and Stress, and low Resilience. Instead, knowledge of the degree of preparedness of the hospital/department, especially in the presence of a predetermined contingency plan for an epidemic and training sessions about protective measures, showed the opposite effect, and were associated with lower psychological vulnerability. All effects were confirmed after accounting for confounding factors related to gender, age, geographical location and the role played by HPs in the hospital/department.ConclusionsDifficult working conditions during the pandemic had a major impact on the psychological wellbeing of emergency department HPs, but this effect might have been lessened if they had been informed about adequate measures for minimizing the risk of exposure.
