Trusted infrastructure needs DINIvolution – the DINI certificate for Open Access publishing services

Research information infrastructure services require transparent criteria and guidelines to be considered trustworthy, i.e. sustainable, interoperable and ready for future challenges. The DINI Certificate for Open Access Publication Services (an English version is currently in preparation) supports these requirements. The community-developed, noncommercial certificate paves the way for open scholarly communication and supports the prerequisites for the free availability of scholarly information as an essential element of future-oriented research-related services. Launched in 2004 and now in its 7th revised version, the DINI certificate has undergone dozens of successful certification processes, and is still unique and can be considered a de facto standard for publishing services, at least in Germany, and a role model for other countries. It is therefore recommended as a guide for publication services by the German Research Foundation (DFG). The DINI Certificate is managed by a team of information experts from research libraries, research organisations and software developers who are organised in the “Electronic Publishing” working group of DINI e.V. DINI or the German Initiative for Networked Information (Deutsche Initiative für Netzwerkinformation) promotes the development of interoperable open and trustworthy information infrastructures and services at research institutions.The DINI Certificate is based on an elaborate set of criteria that takes into account international standards and reflects the current state of technical, organisational and editorial requirements. For certified institutions, the DINI certificate provides a quasiguarantee that their service complies with the requirements of open science and will continue to do so. For others, it provides guidance on implementing a state-of-the-art service. Feedback from the interested community is collected through an open call for comments and taken into account in the revision processes.In the latest certificate (2022), the focus is on supporting users as authors and recipients, the requirements of open science, the sustainability of the service infrastructure, and the desired internationalisation. As a first step towards internationalisation, the certificate has been extended to include the specific requirements for certification of Austrian publication services. Complementary tools and measurements support the effectiveness of the certificate.This presentation will highlight the “DINIverse” − the DINI Certificate and its complementary tools − as a central instrument and inspiration for establishing and maintaining trustworthy Open Access publishing services. In three chapters it will give a brief overview of the origin of the certificate and the continuous adoption of new established requirements as essential parts of the “DINIvolution”, the related workflows, the benefits for users as well as the related services and projects: e.g. supporting tools like the DINI OAI validator, a dynamic overview of publishing services from Germanspeaking countries developed in cooperation with BASE - Bielefeld Academic Search Engine as well as a specialised vocabulary to support compliance with international standards.

Techniques in Preserving Traditional Medicinal Knowledge in uMhlathuze in KwaZulu Natal, South Africa

ABSTRACT This article examined the techniques used in preserving traditional medicinal knowledge in UMhlathuze in KwaZulu Natal, South Africa. Four research objectives guided the study: to determine the types of traditional medicinal knowledge owners in uMhlathuze area; to determine techniques used by traditional medicinal knowledge owners in preserving their traditional medicinal knowledge; to establish the effectiveness of the techniques used by traditional medicinal knowledge owners in preserving their traditional medicinal knowledge and to identify the challenges associated with the preservation of traditional medicinal knowledge. The study adopted qualitative research approach underpinned by the interpretivism research paradigm, in order to understand the techniques or strategies used to preserve traditional medicinal knowledge, guided by Nonaka's knowledge creation model. Qualitative data was collected through interviews (primarily through open-ended questions incorporated in semi-structured interviews with traditional medicinal knowledge practitioners) and content analysis was used for qualitative data obtained from lliterature review and document analysis. The study interviewed fifteen (15) traditional medicinal knowledge practitioners in the province of KwaZulu-Natal, included diviners (Izangoma), herbalists (Izinyanga), and faith healers/prophets (Abathandazi). The study identified the abundance, accessibility, and usage of traditional medicinal knowledge for the benefit of both owners and users of this knowledge. The findings reveal that the traditional medicinal practitioners employed various strategies, such as notebooks and diaries to record and preserve their knowledge. Traditional medicinal knowledge practitioners also passed on their therapeutic experiences to their loved ones. Even though most traditional medicinal knowledge practitioners used a written form of preservation, several obstacles were recognised when conserving knowledge. The lack of education, skills and ability to use technological gadgets to their full potential made conserving traditional medicinal knowledge challenging. The study recommends that traditional medicinal knowledge should be captured, stored, retrieved, and disseminated via technological devices.

Lagrange Multiplier-Based Optimization for Hybrid Energy Management System with Renewable Energy Sources and Electric Vehicles

The issues of energy scarcity and environmental harm have become major priorities for both business and human progress. Hence, it is important and useful to focus on renewable energy research and efficient utilization of distributed energy sources (DERs). A microgrid (MG) is a self-managed system that encompasses these energy resources as well as interconnected consumers. It has the flexibility to function in both isolated and grid-connected configurations. This study aims to design an effective method of power management for a MG in the two operating modes. The proposed optimization model seeks to strike a balance between energy usage, protecting the life of batteries, and maximizing economic benefits for users in the MG, with consideration of the real-time electricity price and constraints of the power grid. Furthermore, in order to accurately account for the dynamic nature of not only the stationary battery banks used as the energy storage systems (ESS) but also the built-in batteries of electric vehicles (EVs), the model is presented as a multi-objective, multiparametric and constrained problem. The solution is proposed to be found using the Lagrange multiplier theory, which helps to achieve good performance with less computational burden. Lastly, simulation results from both the isolated and grid-connected modes also demonstrate the effectiveness of the designed method.

Assessing the Impact of Social and Ecological Change during COVID-19 in Natural Areas Through the Subjective Well-Being and Place Attachment of Natural Area Users

The devastating impact of COVID-19 on the mental health and well-being of individuals has led researchers to increasingly consider the importance of people-place interactions as drivers of positive mental health. This study explores people-place relationships with natural areas through the COVID-19 pandemic, focusing on subjective well-being and place attachment. The study was conducted in a system of natural areas in the Niagara Region, Ontario. Through completion of self-report questionnaires, natural area users identified changes they observed in the natural areas over the COVID-19 pandemic and reported their self-perceived impact of these changes. Findings emphasize the importance of managing social and ecological changes in natural areas to preserve ecological health and user benefits.

Optimization of configurations and scheduling of shared hybrid electric‑hydrogen energy storages supporting to multi-microgrid system

As the energy structure undergoes transformation and the sharing economy advances, hydrogen energy and shared energy storage will become the new norm for addressing future energy demand and user-side storage applications, in order to better meet the flexibility and sustainability requirements of the energy system. This paper focuses on shared energy storage that links multiple microgrids and proposes a bi-layer optimization configuration method based on a shared hybrid electric‑hydrogen storage station for microgrids, combining cooling, heating, and power systems, to better achieve efficient energy utilization and promote sustainable development. The upper-layer model solves the energy storage station capacity configuration problem, while the lower-layer model solves the optimization operation problem of the multi-microgrid system. The lower-layer model is transformed into a constraint condition of the upper-layer model based on the Karush-Kuhn-Tucher condition of the lower-layer optimization model, and the Big-M method is used to linearize nonlinear problems. The rationality and effectiveness of the proposed bi-layer planning model are verified through analytical examples in three different scenarios. The results showed that compared to individual energy storage, shared power storage achieved an average daily net income of $430.00, reduced battery capacity by 75.94 %, and reduced daily operating costs of the microgrids by 11.53 %. Hybrid energy storage increased the daily net income of the energy storage side by 61.67 %, further reduced battery capacity by 67.13 %, and further reduced daily operating costs of the microgrid by 3.39 %. In addition, the optimal capacity allocation of energy storage systems and the operation optimization of multi microgrid systems have been achieved. The results demonstrate that the proposed hybrid energy storage services can effectively reduce user costs, save energy storage resources, and achieve mutual benefits for both users and energy storage operators.

Exploring reasons for usage discontinuation in an internet-delivered stress recovery intervention: A qualitative study

Internet-delivered cognitive behavioral therapy (ICBT) interventions can be as effective as traditional face-to-face therapy for various mental health conditions. However, a significant challenge these online interventions face is the high rate of people who start but then stop using the program. This early discontinuation can be seen as incomplete treatment and can reduce the potential benefits for users. By exploring why people stop using ICBT programs, we can better understand how to address this problem. This study aimed to examine the experiences of healthcare workers who had stopped using a therapist-guided internet-delivered stress recovery program to gain deeper insights into usage attrition. We conducted semi-structured interviews with twelve participants who were female healthcare workers ranging in age from 24 to 68 years (M = 44.67, SD = 11.80). Telephone interviews were conducted and the data were transcribed and analyzed using thematic analysis. Qualitative data analysis revealed that most participants had multiple reasons for discontinuing the program. They identified both barriers and facilitators to using the program, which could be categorized as either personal or program related. Personal aspects included life circumstances, personal characteristics, and psychological responses to the program. Program-related aspects encompassed technical factors, program content, and the level of support provided. The findings of this study can enhance our understanding of why people stop using guided internet-delivered programs. We discuss the practical and research implications, with the ultimate aim of improving the design and efficacy of internet interventions.

Research on the knowledge transfer mechanism of digital platform in the digital innovation ecosystem: an improved model of SIR embedded in symbiosis theory

PurposeIn the digital economy era, digital platforms are vital infrastructure for innovation subjects to perform digital innovation activities. Achieving efficient and smooth knowledge transfer between innovation subjects through digital platforms has become a novel research subject. This study aims to examine the knowledge transfer mechanism of digital platforms in the digital innovation ecosystem through modeling and simulation to offer a theoretical basis for digital innovation subjects to acquire digital value through knowledge-sharing and thus augment their competitive advantage.Design/methodology/approachThis study explores the optimal symbiotic interaction rate between different users based on the classic susceptible-infected-removed (SIR) model. Additionally, it constructs a knowledge transfer mechanism model for digital platforms in the digital innovation ecosystem by combining the theories of communication dynamics and symbiosis. Finally, Matrix Laboratory (MATLAB) software is used for the model and numerical simulation.FindingsThe results demonstrate that (1) the evolutionary path of the symbiotic model is key to digital platforms' knowledge transfer in the digital innovation ecosystem. In the symbiotic model, the knowledge transfer path of digital platforms is “independent symbiosis—biased symbiosis (user benefit)—reciprocal symbiosis,” aligning with the overall interests of the digital innovation ecosystem. (2) Digital platforms' knowledge transfer effects within the digital innovation ecosystem show significant differences. The most effective knowledge transfer model for digital platforms is reciprocal symbiosis, whereas the least effective is parochial symbiosis (platform benefit). (3) The symbiotic rate has a significant positive impact on the evolutionary dynamics of knowledge transfer on digital platforms, especially in the reciprocal symbiosis model.Originality/valueThis study's results aid digital innovators in achieving efficient knowledge transfer through digital platforms and identify how symbiotic relationships affect the knowledge transfer process across the ecosystem. Accordingly, the authors propose targeted recommendations to promote the efficiency of knowledge transfer on digital platforms.

Combining MUSHRA Test and Fuzzy Logic in the Evaluation of Benefits of Using Hearing Prostheses

Assessing the effectiveness of hearing aid fittings based on the benefits they provide is crucial but intricate. While objective metrics of hearing aids like gain, frequency response, and distortion are measurable, they do not directly indicate user benefits. Hearing aid performance assessment encompasses various aspects, such as compensating for hearing loss and user satisfaction. The authors suggest enhancing the widely used APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire by integrating it with the MUSHRA test. APHAB, a self-completed questionnaire for users, evaluates specific sound scenarios on a seven-point scale, with each point described by a letter, percentage, and description. Given the complexities, especially for older users, we propose converting the seven-point APHAB scale to a clearer 100-point MUSHRA scale using fuzzy logic rules. The paper starts with presenting the goals of the study, focused on the assessment of the benefits of hearing aid use, especially in the case of the elderly population. The introductory part includes an overview of methods for evaluating the effectiveness of hearing aid use. Then, the methodology for the data collection is presented. This is followed by a method modification that combines the MUSHRA (MUltiple Stimuli with Hidden Reference and Anchor) test and fuzzy logic processing and the commonly used hearing aid benefit assessment questionnaire, APHAB (Abbreviated Profile of Hearing Aid Benefit). The results of such a process are examined. A summary of the findings is given in the form of fuzzy logic-based rules, followed by a short discussion. Finally, the overall conclusion and possible future directions for the method development are presented.

Community gardens and the 15-minute city: Scenario analysis of garden access in New York City

Community gardens are a form of green infrastructure that provides social and environmental benefits for garden users and the surrounding area. However, little is known about who has walking access to community gardens in most cities today and how this may change in the future. To address this gap, we examine 15-minute walking access to community gardens in New York City (NYC), and how land-use and investment decisions will impact the future of NYC as a 15-minute garden city. Our results indicate that more than half of the city’s residents have this access to a community garden, and that neighborhoods with lower income, lower proportions of white residents and homeowners, and higher rates of educational attainment have better access. Optimization modeling indicates that universal 15-minute access is unlikely, though more than 70% of NYC residents could have walking access with as few as 50 additional community gardens. Supporting new community gardens on vacant land and parking lots is the most efficient way to expand access, though siting community gardens on a range of land use types is required to maximize access. By mapping community gardens, analyzing their distribution, and modeling how to scale-up urban agriculture, this paper presents a scenario-based process for exploring how and where to expand urban amenities.

Effects of Using Websites on Physical Activity and Diet Quality for Adults Living With Chronic Health Conditions: Systematic Review and Meta-Analysis.

Adults with chronic health conditions need support to manage modifiable risk factors such as physical inactivity and poor diet. Disease-specific websites with health information on physical activity and diet quality may be effective in supporting adults in managing their chronic illnesses. The primary aim of this review was to determine whether using websites with health information can lead to improvements in physical activity levels or diet quality in adults with chronic health conditions. Randomized controlled trials evaluating the effectiveness of website use on levels of physical activity or diet quality in adults with chronic health conditions were included. MEDLINE, Embase, CINAHL, and the Physiotherapy Evidence Database were searched from the earliest available record until February 2023. Data for outcomes measuring physical activity levels; diet quality; and, where reported, self-efficacy and quality of life were independently extracted by 2 reviewers. The risk of bias was assessed using the Physiotherapy Evidence Database scale, and the overall certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Where values were presented as the same unit of measure, postintervention scores were pooled for meta-analysis to yield an overall mean difference (MD). A standardized MD (SMD) was calculated for the pooled data in which different units for the same outcome were used. Individual trial data were described in cases where the data of trials could not be pooled. A total of 29 trials (N=6418 participants) across 8 different disease groups with intervention periods ranging from 4 weeks to 12 months were included in the analysis. There was moderate-certainty evidence that using websites with health information increased levels of moderate to vigorous physical activity (MD=39 min/wk, 95% CI 18.60-58.47), quality of life (SMD=0.36, 95% CI 0.12-0.59), and self-efficacy (SMD=0.26, 95% CI 0.05-0.48) and high-certainty evidence for reduction in processed meat consumption (MD=1.1 portions/wk, 95% CI 0.70-1.58) when compared with usual care. No differences were detected in other measures of diet quality. There was no increased benefit for website users who were offered additional support. The use of websites for risk factor management has the potential to improve physical activity levels, quality of life, and self-efficacy as well as reduce processed meat consumption for adults living with chronic health conditions when compared with usual care. However, it remains unclear whether using websites leads to meaningful and long-lasting behavior change.

The Impact of User Benefits on Continuous Contribution Behavior Based on the Perspective of Stimulus–Organism–Response Theory

With the rapid development of the Internet, enterprises have integrated internal and external innovation resources through the establishment of open innovation communities, guided users to participate in innovation activities, and promoted product improvement and development. Users’ continuous contribution behavior is a key factor for open innovation communities to achieve sustainable development, yet most communities do not collect enough data on them. This study investigates the mechanism of user benefits on continuous contribution behavior in open innovation communities based on the Stimulus–Organism–Response (S-O-R) theory, which creatively takes self-verification as a member of the organism (O). This was chosen to overcome the aforementioned issues. Based on the questionnaire data of 469 users in open innovation communities, the SEM method was applied to test the relationship between user benefits, self-verification, and continuous contribution behavior, and the moderating role of future work self-salience on self-verification. The empirical results show that user benefits positively affected both continuous contribution behavior and self-verification. Self-verification positively affected continuous contribution behavior and mediated the relationship between economic, functional, and self-fulfillment benefits and continuous contribution behavior. Meanwhile, future work self-salience positively moderated the relationship between these three types of benefits and self-verification. These findings provide a theoretical basis for the sustainable development of open innovation communities and guiding users to engage in continuous contribution behavior.

Long-Term Outcomes of Eladocagene Exuparvovec Compared with Standard of Care in Aromatic L-Amino Acid Decarboxylase (AADC) Deficiency: A Modelling Study.

Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare disease with symptoms including movement disorders, developmental delays, and autonomic symptoms starting from birth; further, patients with AADC deficiency are at a high risk of death in the first decade of life. Limited information on the impact of treatment with gene therapy on patients' disease trajectories and survival, quality-of-life, and resource usage benefits are available. A cohort-based model with a lifetime horizon has been developed, based on motor milestones, to estimate the long-term benefits for patients after treatment with eladocagene exuparvovec compared to best supportive care (BSC). The model takes a National Health Service (NHS) perspective using a UK setting. The model comprises two parts: the developmental phase, in which patients with initially no motor function can progress to other motor milestone states, and a long-term projection phase. Efficacy for eladocagene exuparvovec is derived from clinical trial data with a duration up to 120months. As the incidence of AADC deficiency is low, data for key model inputs is lacking; therefore estimates of survival by motor milestone were based on proxy diseases. A disease-specific utility study provided quality of life inputs and a burden of illness study informed inputs for disease management. The model indicates survival (25.25 undiscounted life years gained) and quality-of-life benefits (20.21 undiscounted quality-adjusted life years [QALYs] gained) for patients treated with eladocagene exuparvovec compared to BSC. Resource usage costs are greater for patients treated with eladocagene exuparvovec, mainly due to the increased life expectancy during which patients accrue additional healthcare resource usage. Scenario analyses indicate robust results. This study assessed long-term outcomes for patients with AADC deficiency. Patients treated with eladocagene exuparvovec were found to have improved survival and quality of life benefits compared to patients treated with BSC.

Assessing user benefits and privacy concerns in utilitarian and hedonic mobile augmented reality apps

PurposeThe application of mobile augmented reality (MAR) for enhancing user experiences and consumer patronizing intention has been the focus of recent MAR literature. Few studies examine the differences between apps. This study fills the research gap by examining how consumers assess their experiences with different MAR applications and how their decision-making process is performed, particularly in the setting of smartphones.Design/methodology/approachA web-based online survey was administered to collect data on consumers' perceptions of two different MAR apps: utilitarian and hedonic apps. Reliability and validity of the measurement scales, non-response bias and comment method bias were assessed. With the support of measurement model, partial least square (PLS) was employed to test the research hypotheses.FindingsThis study reveals that the technological attributes of augmented reality (AR) apps have significant effects on consumer perceptions of their utilitarian and hedonic benefits, including interactivity, visual quality, service quality, technicality and aesthetics. Moreover, this study shows that consumers of hedonic apps place more importance on their enjoyment with the MAR app; consumers of utilitarian apps focus more on the accrued functional values. The findings provide practical insights for retailers in AR marketing and application development in the MAR environment.Originality/valueThis study provides a comprehensive viewpoint for analyzing ongoing use and purchase intentions simultaneously in a unified theoretical framework. In addition, it compares different types of MAR apps: hedonic and utilitarian. Furthermore, it is one of the first few studies attempting to provide a comprehensive understanding of the predictive role of MAR technologies by incorporating privacy concerns into the research model based on user and gratification framework.

The impact of green innovation on sustainability and financial performance: Evidence from the Jordanian financial sector

AbstractThe purpose of this study is to examine the relationship between sustainability performance (SP) and financial performance (FP), based on performance disclosures (reporting) of the Jordanian financial sector for the period of 2017–2020. The study employs green innovation (GI) indicators as moderating and mediating variables; by using hierarchical regression; as means of unlocking and examining the relationship between SP and FP; through the lens of the stakeholder theory. The hierarchical regression findings suggest that GI indicators partially mediate the relationship between SP and FP, but do not demonstrate a moderating effect. As a main result, it is indicated that Jordanian financial institutions may use SP transparency indicators as an incentive variable, which could influence their overall FP. The research also contributes to the existing literature by adding insight into the use of GI indicators in a developing country and the potential impact on financial institutions markets. These findings lend empirical credence to the generally held belief that increase disclosure benefits for both internal and external users.

Pilot study: design, delivery and evaluation of a co-produced multi-agency mental health simulation-based education programme

Research shows inequity of access and provision of Simulation-Based Education (SBE) globally, perhaps especially for Simulation for Mental Health (S4MH). Integrated approaches to education improve outcomes, despite this, there is a lack of multi-agency education and service user/carer involvement. This innovative work involves service users and carers in the design, delivery and evaluation of an experiential, mental health, SBE programme for health and social care professionals, and multi-agencies. Highlighting important areas of inclusivity, equality and diversity provides valuable insight into the unique patient perspective and experience of their interactions with services and professionals, and knowledge, perspective, and role of the practitioner, considering the transition of the service user between services. In a mixed approach, data was collected between November 2021 and March 2022 by pre- and post-participation survey of participants’ thoughts, beliefs, attitudes, behaviours and experiences of the programme. A thematic method was used for qualitative data analysis. Completed survey response rate = 64%. Analyses constructed themes around safety, responsiveness, empathy, stigma and experience. Findings show increased confidence and understanding of roles following participation in the programme. Positive changes in empathy and respondents’ perspectives and behaviours were also reported. Findings inform better integrated, co-ordinated systems and practices, demonstrating mutual benefits of service user and carer involvement, and value of multi-agency learning; increased knowledge, safety, empathy, mutual appreciation of roles and recognition in the value of lived experience integrated into learning. Implications for practice and mental health care are relevant to multi-agency professionals, service providers, service users, carers and families.

Impact of Social Media Usage on Financial and Non-Financial Performance of Organization through Social CRM

Social media usage improves Social Customer Relationship Management (CRM) is highly important for modern firms to create value for business after the rapid growth of technology adoption by customers. Studies on social media and organizational performance are limited so the present study has to extend this topic for a brief analysis of this domain. Hence, the current study aims to investigate further how social media usage benefits both financial and non-financial aspects of organizational performance through social CRM. A quantitative cross-sectional research design was carried out to collect the primary information using a structured questionnaire using two separate surveys; one was filled out by the top management of the organizations while the other was filled out by the respective customer of the organizations from different sectors of Pakistan which were also active on Facebook and lastly each 209 participants in both surveys were selected for data analysis. AMOS and Smart PLS were employed to test this proposed model. All findings of this study are found significantly positive and the social CRM acts as a positive mediator between the direct association of social media usage and organizational performance. Furthermore, the present study offers marketers and businessmen to explain the linkage of CRM with advancing social media technologies to improve organizational performance either financial or non-financial performance.

Individual Differences in Auditory Training Benefits for Hearing Aid Users.

The present study aimed to examine whether individual differences in baseline speech perception could serve as predictors for the effectiveness and generalization of auditory training (AT) to non-trained tasks. Twelve adults, aged 60-75 years with bilateral hearing loss, completed a two-month, home-based, computerized AT program, involving sessions four times per week. Training tasks included the identification of vowel frontal, height, manner of articulation, point of articulation, voicing, and open-set consonant-vowel-consonant (CVC) words. Non-trained speech perception tests were conducted one month before AT, prior to training, after one and two months of training, and during a two-month follow-up. The results showed that one month of AT improved performance in most trained tasks, with generalization observed in the CVC words test and HeBio sentences with speech-shaped noise (SSN). No evidence of spontaneous learning or added benefit from an extra month of training was found. Most importantly, baseline speech perception predicted improvements in both training and post-training generalization tasks. This emphasizes the significance of adopting an individualized approach when determining the potential effectiveness of AT, applicable in both clinical and research contexts.
