Using Formal Knowledge to Support Episodic Evidence-Based Nursing Care.

Applying evidence-based medicine prevents medical errors highlighting the need for applying Clinical Guidelines (CGs) to improve patient care by nurses. However, nurses often face challenges in utilizing CGs due to patient-specific needs. Developing a Clinical Decision Support System (CDSS) can provide real-time context-sensitive CG-based recommendations. Therefore, there is a need to acquire and represent CGs in a machine-applicable manner. Also, there is a need to be able to provide recommendations episodically, only when requested, and not continuously, and to assess previous partial performance of evidence-based actions on a continuous scale. This study evaluated the feasibility of acquiring and representing major nursing CGs, in a machine-applicable manner for episodic use. Using data from an Israeli geriatric center, the results suggest that an episodic CDSS effectively supports the application of formalized nursing knowledge.

Opportunities and challenges for circular economy in the Maldives: A stakeholder analysis of informal E-waste management in the Greater Malé Region.

In the Maldives, the contribution of the informal sector to e-waste management is significant as a formal e-waste management system is not yet established. The opportunities for advancing the circular economy in the Maldives' e-waste sector rely on the possibility of its formalization. This study aimed to examine the current and anticipated situations of e-waste management in the Greater Malé Region of the Maldives, with a specific focus on formalizing the informal sector. Interviews and questionnaire-based surveys were conducted followed by statistical analysis of the data. The t-test performed for the consumer survey data (n = 202) suggests that formalization encourages consumers to engage with the informal sector, resulting in increased resource recovery. Thematic analysis of interviews conducted with both formal and informal sector stakeholders (n = 17) revealed that the informal sector plays a substantial role in managing e-waste. It also underscored the need for government assistance to enhance safety and productivity in this sector. Various opportunities and challenges for establishing a circular economy in the country were identified, such as the rise in e-waste generation, the presence of an active informal workforce, the lack of sufficient government support, and prevailing stereotypes among consumers regarding informal workers. These findings provide a fresh perspective on the solutions for waste management in the Maldives and open the door to further explore the significance of the informal sector and feasible formalization initiatives. This study could contribute to the literature on the role of the informal sector in waste management in the Maldives and other small island developing states.

First-Order Theory of Rewriting for Linear Variable-Separated Rewrite Systems: Automation, Formalization, Certification.

The first-order theory of rewriting is decidable for linear variable-separated rewrite systems. We present a new decision procedure which is the basis of FORT, a decision and synthesis tool for properties expressible in the theory. The decision procedure is based on tree automata techniques and verified in Isabelle. Several extensions make the theory more expressive and FORT more versatile. We present a certificate language that enables the output of FORT to be certified by the certifier FORTify generated from the formalization, and we provide extensive experiments.

Who would rescue the dilemma of Chinese elderly care? An evolutionary game analysis and simulation research on the formalization of the domestic service industry with subsidy policy.

Since China entered the aging society, the surging demand for elderly care and the industrial upgrading of "silver economy" has forced the domestic service industry to face endogenous challenges. Among them, the formalization of the domestic service industry can effectively reduce the transaction costs and risks of actors, innovate the endogenous vitality of the industry, and promote the improvement of elderly care quality through a triangular employment relationship. By constructing a tripartite asymmetric evolutionary game model of clients, domestic enterprises and governmental departments, this study uses the stability theorem of differential equations to explore the influencing factors and action paths of the system's evolutionary stable strategies (ESS), and uses the research data collected from China to assign values to models for simulation analysis. This study finds that the ratio of the initial ideal strategy, the difference between profits and costs, subsidies to clients, and subsidies or punishments for breach of contract to domestic enterprises are the key factors affecting the formalization of the domestic service industry. Subsidy policy programs can be divided into long-term and periodic programs, and there are differences in the influence paths and effects of the key factors in different situations. Increasing domestic enterprises' market share with employee management systems, formulating subsidy programs for clients, and setting up evaluation and supervision mechanisms are efficient ways through which to promote the formalization of the domestic service industry in China. Subsidy policy of governmental departments should focus on improving the professional skills and quality of elderly care domestic workers, and also encourage domestic enterprises with employee management systems at the same time, to expand the scope of service beneficiaries by running nutrition restaurants in communities, cooperating with elderly care institutions, etc.

Towards semantic-driven boolean query formalization for biomedical systematic literature reviews.

OBJECTIVE: Study identification refers to formalizing an effective search over biomedical databases for retrieving all eligible evidence for a systematic review. Manual construction of queries, where a user submit a search query for which a biomedical search system such as PubMed would identify the most relevant documents, has been recognized as a very costly step in conducting systematic reviews. The objective of this paper is to present an automatic query generation approach to reduce the time and labor cost of manual biomedical study identification. MATERIALS AND METHODS: The evaluation benchmark is the widely adopted CLEF 2018 Technology Assisted Reviews (TAR) collection, with 72 systematic reviews on Diagnosis Test Accuracy. We use and fine-tune pre-trained language models for generating high-level key-phrases and their dense embeddings. We constructed and published a dataset consists of almost one million PubMed articles' abstracts and their keywords for fine-tuning pre-trained language models. We also use concepts that are represented in the Unified Medical Language System, UMLS, for query expansion and embedding generation. We exploit and test different clustering methods, namely Agglomerative clustering, Affinity Propagation, and K-Means, over the generated embeddings to form query clauses. RESULTS: Our proposed methods outperform existing state-of-the-art automatic query generation models across Precision (0.0821 compared with 0.005), Recall (0.9676 compared with 0.878), and F-measures (0.2898 compared with 0.0356 in F3 measure). In addition, some of the proposed methods can even outperform the performance of the manually crafted queries in some specific measures. CONCLUSION: The proposed model in this paper can be utilized to form an effective initial search query that can be further refined and updated by human reviewers for achieving the desired performance. For future work, we would like to explore the application of the presented query formalization methods in existing study identification methodologies and techniques, especially those that iteratively train machine learning models based on the domain experts' feedback on the relevancy of the retrieved studies.

The Key to Work-Life Balance is (Enriched) Job Design? Three-Way Interaction Effects with Formalization and Adaptive Personality Characteristics.

The COVID-19 outbreak has blurred the boundaries between work and personal life, making the concept of work-life balance (WLB) even more important. Based on a three-source (employees, family members, and supervisors) sample (n = 436) of working professionals, we investigated the importance of enriched job design for employee WLB. In addition, on the basis of the job demand-control (JD-C) model, we examined whether organizationally imposed formalization and employees' individual adaptive personality traits (proactive personality and resilience) act as boundary conditions that strengthen this positive relationship. First, we conducted a supplementary analysis to investigate further which of the enriched job design characteristics play the most important role in our three-way interaction models predicting WLB. Then we discuss implications for theory and practice.

A Formalization of SQL with Nulls.

SQL is the world's most popular declarative language, forming the basis of the multi-billion-dollar database industry. Although SQL has been standardized, the full standard is based on ambiguous natural language rather than formal specification. Commercial SQL implementations interpret the standard in different ways, so that, given the same input data, the same query can yield different results depending on the SQL system it is run on. Even for a particular system, mechanically checked formalization of all widely-used features of SQL remains an open problem. The lack of a well-understood formal semantics makes it very difficult to validate the soundness of database implementations. Although formal semantics for fragments of SQL were designed in the past, they usually did not support set and bag operations, lateral joins, nested subqueries, and, crucially, null values. Null values complicate SQL's semantics in profound ways analogous to null pointers or side-effects in other programming languages. Since certain SQL queries are equivalent in the absence of null values, but produce different results when applied to tables containing incomplete data, semantics which ignore null values are able to prove query equivalences that are unsound in realistic databases. A formal semantics of SQL supporting all the aforementioned features was only proposed recently. In this paper, we report about our mechanization of SQL semantics covering set/bag operations, lateral joins, nested subqueries, and nulls, written in the Coq proof assistant, and describe the validation of key metatheoretic properties. Additionally, we are able to use the same framework to formalize the semantics of a flat relational calculus (with null values), and show a certified translation of its normal forms into SQL.

Transition from the Informal to the Formal Economy: The Need for a Multi-faceted Approach.

The recent international attention paid to the formalization of the informal economy finds reflection in ILO Recommendation No. 204 concerning the transition from the informal to the formal economy and the Sustainable Development Goals (Target 8.3). There is great diversity within the categories of the informal sector, informal employment, and informal economy in India. This paper examines the category of the 'informal economy' as understood in international instruments as well as in international statistics and maps these onto legal categories recognized within Indian law. The categories of 'employed', 'engaged', and 'work arrangement' used in Indian laws, and their interpretation by the courts, are useful to understand the links between the concepts of work, employment, and livelihoods. The paper also focuses on the diversity of the informal economy, focusing on wage employment, self-employment, including the diverse forms of own-account work and contributing (unpaid) family labour. The categorization of gig and platform workers as own-account or waged workers continues to pose a normative challenge. The regulatory responses for formalization of each segmented category of informal workers and informal enterprises cannot be uniform, and neither do they need to be linked to any particular domain of the law. Moving beyond the extension of social security coverage as the key vehicle for formalization, the paper suggests various entry points through which law and policy can improve conditions of work and protect the livelihood of those in the informal economy as measures to achieve formalization.

Factors affecting faculty conformity in South China universities.

Based on social contagion theory, this study examines the mediating role of formalization of organizational structure between organizational identification and faculty conformity. It also analyzes the moderating role of conflict management style between organizational identification and faculty conformity, and formalization of organizational structure and faculty conformity in universities in Hunan province, China. Convenience sampling was employed to select the subjects, and 1,024 Chinese faculty members including teaching staff and administrative staff were surveyed online with the questionnaire consist of organizational identification scale, organizational formalization scale, conflict management style scale, and faculty conformity scale. 1,000 valid respondents were collected and SPSS was used to analyze the data through descriptive analysis, analysis of variance, correlation analysis, and hierarchical multiple regression. The results showed that faculty members' organizational identification had a positive effect on faculty conformity; formalization of organizational structure partially mediated the relationship between organizational identification and faculty conformity; and conflict management style positively moderated the relationship between organizational identification and faculty conformity and between formalization of organizational structure and faculty conformity. University administrators are often the initiators of conformity as they are responsible for formulating internal regulations. Therefore, they must monitor and coordinate workplace conflicts, resolve and guide faculty conformity, promote individual faculty members' self-improvement, and foster steady organizational development.

Interprofessional Collaboration in the OR: A Qualitative Study of Nurses' Perspectives.

Interprofessional collaboration (IPC) in the OR enhances safe and effective patient care. The aim of this qualitative study was to explore perioperative nurses' perspectives on their contributions to IPC. We conducted a secondary analysis of 19 semistructured interviews with perioperative RNs and completed inductive thematic analysis with subsequent categorization of the themes into the Interprofessional Education for Collaborative Patient-Centred Practice Framework. Nurses expressed the importance of being heard through effective communication, feeling confident in their role, being aware of interdependent roles, and sharing a common understanding. From nurses' perspectives, use of structured processes enabled organization of interdisciplinary patient care. Nurses showed leadership skills when they anticipated the needs of the team and recognized they needed support to develop these skills. They contributed to IPC through their shared understanding of common goals, leadership skills in the OR, and active involvement in delivering structured processes.

Stakeholders' perspectives and willingness to institutionalize linkages between the formal health system and informal healthcare providers in urban slums in southeast, Nigeria.

BACKGROUND: The widely available informal healthcare providers (IHPs) present opportunities to improve access to appropriate essential health services in underserved urban areas in many low- and middle-income countries (LMICs). However, they are not formally linked to the formal health system. This study was conducted to explore the perspectives of key stakeholders about institutionalizing linkages between the formal health systems and IHPs, as a strategy for improving access to appropriate healthcare services in Nigeria. METHODS: Data was collected from key stakeholders in the formal and informal health systems, whose functions cover the major slums in Enugu and Onitsha cities in southeast Nigeria. Key informant interviews (n = 43) were conducted using semi-structured interview guides among representatives from the formal and informal health sectors. Interview transcripts were read severally, and using thematic content analysis, recurrent themes were identified and used for a narrative synthesis. RESULTS: Although the dominant view among respondents is that formalization of linkages between IHPs and the formal health system will likely create synergy and quality improvement in health service delivery, anxieties and defensive pessimism were equally expressed. On the one hand, formal sector respondents are pessimistic about limited skills, poor quality of care, questionable recognition, and the enormous challenges of managing a pluralistic health system. Conversely, the informal sector pessimists expressed uncertainty about the outcomes of a government-led supervision and the potential negative impact on their practice. Some of the proposed strategies for institutionalizing linkages between the two health sub-systems include: sensitizing relevant policymakers and gatekeepers to the necessity of pluralistic healthcare; mapping and documenting of informal providers and respective service their areas for registration and accreditation, among others. Perceived threats to institutionalizing these linkages include: weak supervision and monitoring of informal providers by the State Ministry of Health due to lack of funds for logistics; poor data reporting and late referrals from informal providers; lack of referral feedback from formal to informal providers, among others. CONCLUSIONS: Opportunities and constraints to institutionalize linkages between the formal health system and IHPs exist in Nigeria. However, there is a need to design an inclusive system that ensures tolerance, dignity, and mutual learning for all stakeholders in the country and in other LMICs.

Formalizing Phenotypes of Regeneration.

Regeneration experiments can produce complex phenotypes including morphological outcomes and gene expression patterns that are crucial for the understanding of the mechanisms of regeneration. However, due to their inherent complexity, variability between individuals, and heterogeneous data spreading across the literature, extracting mechanistic knowledge from them is a current challenge. Toward this goal, here we present protocols to unambiguously formalize the phenotypes of regeneration and their experimental procedures using precise mathematical morphological descriptions and standardized gene expression patterns. We illustrate the application of the methodology with step-by-step protocols for planaria and limb regeneration phenotypes. The curated datasets with these methods are not only helpful for human scientists, but they represent a key formalized resource that can be easily integrated into downstream reverse engineering methodologies for the automatic extraction of mechanistic knowledge. This approach can pave the way for discovering comprehensive systems-level models of regeneration.

Collaboration between general dental practitioners and dental hygienists: a qualitative study.

BACKGROUND: Influenced by governmental measures, collaboration in oral health care practices in the Netherlands has increased in recent decades. Previous studies on this subject have mainly concerned the composition of the staff or have been normative rather than descriptive. Based on the existing literature, four aspects were expected to be of significant influence on the collaboration on oral health care practices: goals, leadership, the allocation of tasks and responsibilities and formalization. METHODS: The aim of this study was to describe a classification of collaboration between general dental practitioners and dental hygienists within oral health care practices in the Netherlands. Eighteen semi-structured face-to-face interviews were conducted in nine oral health care practices, which differed with regard to both practice characteristics and characteristics of the principal general dental practitioner. In all practices, the principal general dental practitioner and one dental hygienist were consulted. The interviews were conducted in the practices of the respondents and were held between October 2019 and July 2020. The interviews were analyzed through theoretical thematic analysis using Microsoft Word 2010 and Atlas.ti 8. Three researchers coded and analyzed three practices, and discussed their results. Based on their mutual conclusions, one researcher analysed all practices. The final results were reviewed and approved by the other two researchers. RESULTS: Different factors influencing the collaboration between general dental practitioners and dental hygienist in the Netherlands were found. The most important factors seemed to be leadership style and goals for collaboration. Leadership style varied from very directive to very supportive and seemed to be connected to the allocation of responsibilities. Goals for collaboration varied from predominantly patient-related to mostly practice-related. Formalization appeared to be more present in larger practices and practices that are affiliated to a dental chain. CONCLUSIONS: Based on leadership style and goals for collaboration, a classification was identified. This classification is recommended as a starting point for further research on directive and supportive leadership in oral health care practices.

A Formal Validation Approach for XACML 3.0 Access Control Policy.

Access control systems represent a security mechanism to regulate the access to system resources, and XACML is the standard language for specifying, storing and deploying access control policies. The verbosity and complexity of XACML syntax as well as the natural language semantics provided by the standard make the verification and testing of these policies difficult and error-prone. In the literature, analysis techniques and access control languages formalizations are provided for verifiability and testability purposes. This paper provides three contributions: it provides a comprehensive formal specification of XACML 3.0 policy elements; it leverages the existing policy coverage criteria to be suitable for XACML 3.0; and it introduces a new set of coverage criteria to better focus the testing activities on the peculiarities of XACML 3.0. The application of the proposed coverage criteria to a policy example is described, and hints for future research directions are discussed.

The interplay of labor and capital perspectives on formalization approaches: motorcycle taxi drivers in Bangkok.

Motorcycle taxi drivers (MTDs) are classified as self-employed informal workers. The interplay between formality and informality is examined in this article from labor and capital perspectives on formalization approaches. Data was collected by questionnaire survey and semi-structured interview methods and analyzed. Results revealed significant overlap and informality concealed within formality, as well as stakeholder illegal practice in occupational registration and social assistance programs as well as factors affecting short-term cash transfer programs during the Novel Coronavirus 2019 (COVID-19) pandemic. These findings suggest that 1) The Bangkok Metropolitan Administration (BMA) should be held accountable for responses caused by its urban transportation network; and 2) government agencies should address institutionalized corruption in the motorcycle taxi trade as an underlying cause of unproductive means-testing in providing social assistance during a pandemic.

Static Analysis of Information Systems for IoT Cyber Security: A Survey of Machine Learning Approaches.

Ensuring security for modern IoT systems requires the use of complex methods to analyze their software. One of the most in-demand methods that has repeatedly been proven to be effective is static analysis. However, the progressive complication of the connections in IoT systems, the increase in their scale, and the heterogeneity of elements requires the automation and intellectualization of manual experts' work. A hypothesis to this end is posed that assumes the applicability of machine-learning solutions for IoT system static analysis. A scheme of this research, which is aimed at confirming the hypothesis and reflecting the ontology of the study, is given. The main contributions to the work are as follows: systematization of static analysis stages for IoT systems and decisions of machine-learning problems in the form of formalized models; review of the entire subject area publications with analysis of the results; confirmation of the machine-learning instrumentaries applicability for each static analysis stage; and the proposal of an intelligent framework concept for the static analysis of IoT systems. The novelty of the results obtained is a consideration of the entire process of static analysis (from the beginning of IoT system research to the final delivery of the results), consideration of each stage from the entirely given set of machine-learning solutions perspective, as well as formalization of the stages and solutions in the form of "Form and Content" data transformations.

Features of hardware implementation of quasi-continuous observation devices with discrete receivers.

This article proposes an approach to the formalization of tasks and conditions for the hardware implementation of quasi-continuous observation devices with discrete receivers in remote sensing systems. Observation devices with a matrix are used in medicine, ecology, aerospace photography, and geodesy, among other fields. In the discrete receivers, the sampling of an image in the matrix receiver into pixels leads to a decrease in the spatial information of the object. In a greater extent, these disadvantages can be avoided by using photosensitive matrix with a regularly changing (controlled) density of elementary receivers-matrix (RCDOER-matrix). Currently, there is no substantiation of the tasks and conditions for the hardware implementation of RCDOER-matrix. The algorithmic formation of a quasi-continuous image of observation devices with the RCDOER-matrix is proposed. The algorithm used a formal pixel-by-pixel description of the signals in the image. This algorithm formalizes the requirements for creating a photosensitive RCDOER-matrix of a certain size, as well as for changing the mechanism for forming and saving a frame with observation results. The application of the developed method will allow multiplying the pixel size of the image relative to the pixel size of the RCDOER-matrix. Developed algorithms for RCDOER-matrix are supplemented by formalizing the tasks that arise when creating prototypes. In addition, the conditions for hardware implementation are proposed, which ensure the completeness of registration of the observation picture, and allow avoiding excessive pixel measurements. Thus, the results of the research carried out approximate the practical application of RCDOER-matrix.

Formalization of the Burning Process of Virtual Reality Objects in Adaptive Training Complexes.

Within the scope of this article, the problem of the formalization of physical processes in adaptive training complexes is considered on the example of virtual objects burning. Despite a fairly complete study of this process, the existing mathematical models are not adapted for the application in training complexes, which leads to a significant increase in costs and lower productivity due to the complexity of the calculations. Therefore, an adapted mathematical model is proposed that allows us to formalize the structure of virtual objects of burning, their basic properties and the processes of changing states, starting from the flame development of an object and ending with their complete destruction or extinguishment. The article proposes the use of threshold value diagrams and rules for changing the states of virtual reality objects to solve the problem of the formalization of burning processes. This tool is quite multi-purpose, which allows you to describe various physical processes, such as smoke, flooding, the spread of toxic gases, etc. The area of the proposed formalization approach includes the design and implementation of physical processes in simulators and multimedia complexes using virtual and augmented reality. Thus, the presented scientific research can be used to formalize the physical processes in adaptive training complexes for professional ergatic systems.

The influence of team mindfulness on nurses' presenteeism: A cross-sectional study from the perspective of sensemaking.

AIM: This study explores the influence of team mindfulness on nurses' presenteeism. The mediation effect of perceived empathic concern and perceived insider status and the moderating effect of organisational formalization are assessed. BACKGROUND: Nurses are prone to presenteeism. Few studies have explored the influence of the organisational environment on nurses' presenteeism. Studies that consider organisational, work-related and person-related factors on the decision-making process influencing nurses' presenteeism are scarce. METHODS: Using a cross-sectional survey, data from 396 nurses were gathered from three time points and multiple regression analyses were used to test each hypothesis. RESULTS: (a) Team mindfulness reduces nurses' presenteeism. (b) Both perceived empathic concern and perceived insider status mediate the relationship between team mindfulness and nurses' presenteeism. (c) Organisational formalization exerts a positive moderating effect on the relationship between team mindfulness and perceived empathic concern. CONCLUSIONS: Team mindfulness reduces nurses' presenteeism through affective (perceived empathic concern) and cognitive (perceived insider status) sensemaking paths. Organisational formalization is a situational factor to improve the effectiveness of team mindfulness. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers need to devote themselves to cultivating team mindfulness, building an atmosphere to promote perceived empathic concern and perceived insider status, and promoting a formal organisational structure.
