Pair counting without binning - a new approach to correlation functions in clustering statistics

Abstract This paper presents a novel perspective on correlation functions in the clustering analysis of the large-scale structure of the universe. We begin with the recognition that pair counting in bins of radial separation is equivalent to evaluating counts-in-cells (CIC), which can be modelled using a filtered density field with a binning-window function. This insight leads to an in situ expression for the two-point correlation function (2PCF). Essentially, the core idea underlying our method is to introduce a window function to define the binning scheme, enabling pair-counting without binning. This approach develops an idea of generalised 2PCF, which extends beyond conventional discrete pair counting by accommodating non-sharp-edged window functions. In the context of multiresolution analysis, we can implement a fast algorithm to estimate the generalised 2PCF. To extend this framework to N-point correlation functions (NPCF) using current optimal edge-corrected estimators, we developed a binning scheme that is independent of the specific parameterisation of polyhedral configurations. In particular, we demonstrate a fast algorithm for the three-point correlation function (3PCF), where triplet counting is accomplished by assigning either a spherical tophat or a Gaussian filter to each vertex of triangles. Additionally, we derive analytical expressions for the 3PCF using a multipole expansion in Legendre polynomials, accounting for filtered field (binning) corrections. Our method provides an exact solution for quantifying binning effects in practical measurements and offers a high-speed algorithm, enabling high-order clustering analysis in extremely large datasets from ongoing and upcoming surveys such as Euclid, LSST, and DESI.

Functional outcomes of patients in the medical and trauma critical care units using the chelsea critical care physical assessment tool

Abstract Background Outcome measures in clinical practice assist in establishing progress for effective quality of care. Physiotherapists in the intensive care unit (ICU) promote lung function and facilitate early mobilization to prevent ICU-related complications. Objectives To determine the physical functional outcomes in critically ill patients in the trauma and medical critical care units at three hospitals in the Tshwane District. Method This was a quantitative prospective observational cohort study. Adult patients admitted in the trauma, medical ICU, and high care (HC) units were recruited. Ethical clearance was obtained from the [Masked for blind review], the National Department of Health Research (NHRD), and the Chief Executive Officers (CEOs) of the hospitals. Written consent was obtained from the recruited patients. Assessments were done on Mondays, Wednesdays, and Fridays using the Chelsea Critical Care Physical Assessment (CPAx) Tool until discharge from the units. Data were analyzed using SPSS version 28. Results Functional outcomes that improved quicker were respiratory function, cough reflex, rolling in the bed, and grip strength. An increase in CPAx scores correlated with improvement in the Glasgow coma scale (GCS) in both groups. Median and inter-quartile CPAx scores in the medical ICU for the initial assessments were 3(2–8) with an increase to 8(3.75–28.25) in the final assessment (p = 0.003). The median and interquartile CPAxs scores for initial assessments in the trauma ICU were 2(1–11.75) and 5(3.25–14) for the final assessments, with a p-value of 0.005 which showed statistical significance. Conclusion CPAx mean scores in the trauma ICU were higher than in the medical ICU. There were significant positive changes in the scoring of both populations but this was slightly better in the trauma ICU. Using the CPAx tool in a HC setting seemed feasible and patients showed higher scores compared to both trauma and medical ICU. Clinical implications The CPAX tool assists in the development of rehabilitation goals in the ICU and HC by physiotherapists. The tool can be adapted in the medical and trauma critical care units to assess functional outcomes.

FHG-PR: a hybridized fuzzy-AHP and game theory model for assessing privacy risk on social media platforms

Social media platforms have become integral to our daily lives, enabling global connectivity and interaction. Current research provides general solutions for mitigating privacy risks, but it does not focus on particular platforms. However, the voluntary sharing of personal information on these platforms presents considerable privacy risks, highlighting the need for effective risk assessment mechanisms. This study presents a hybrid approach that uses the fuzzy Analytical Hierarchy Process (AHP) and game theory to estimate privacy risks on Meta and X. We used a fuzzy AHP to rank determinant variables based on surveys of social media users and professionals. These weighted criteria were then used in a Multi-Criteria Decision-Making (MCDM) framework using cooperative game theory to discover ways to lower privacy hazards. The model accurately analyzed the privacy threats on Meta and X, recommending alternate techniques for preventing breaches in data privacy. The cooperative game theory method allows stakeholders to collaborate on creating privacy-preserving measures. The findings emphasize the model’s ability to address platform-specific privacy threats, as well as its flexibility in other social media settings. The model’s potential for real-world application is demonstrated by its ability to provide practical risk reduction measures, which improve privacy protection for social media users.

TVT‐Based New Building Block with Enhanced π‐Electron Delocalization for Efficient Non‐Fused Photovoltaic Acceptor

AbstractTo address the high‐cost issue that impedes the large‐scale fabrication and industrialization of organic solar cells (OSCs), it is crucial to design low‐cost photovoltaic materials with simplified synthesis procedures. In this study, a novel fully non‐fused acceptor, ATVT‐BO, featuring a triisopropylbenzene‐substituted (E)‐1,2‐di(thiophen‐2‐yl)ethene (TVT) unit as the central core is designed and synthesized. A control acceptor, A4T‐BO, with the same alkyl chains but a bithiophene central core, is also synthesized for comparison. Theoretical calculations and practical measurements reveal that compared to A4T‐BO, the insertion of an ethylene bond in ATVT‐BO enhances the molecular planarity and reduces the aromaticity, leading to enhanced π‐electron delocalization and thus improved electron mobility and a red‐shifted optical absorption spectrum. The 3D molecular packing mode of ATVT‐BO, characterized by tight intermolecular interactions, also promotes efficient charge transport in OSCs. Consequently, when paired with the low‐cost polymer PTVT‐T, featuring an ester‐substituted TVT structure, as the photoactive layer, the PTVT‐T:ATVT‐BO‐based device achieves a remarkable power conversion efficiency of 14.8%, distinctly higher than that of PTVT‐T:A4T‐BO‐based cell. The result highlights the significant potential of TVT units in creating both low‐cost polymer donors and fully non‐fused acceptors, which opens up new possibilities for designing low‐cost photoactive materials in OSCs.

DENAZIFICATION OF THE IDEOLOGY OF NATIONAL SOCIALISM IN OCCUPIED GERMANY 1945–1949

The policy of denazification pursued by the victors in occupied Germany, which is discussed in the article, is reflected in published sources, research, and memoirs. However, most of them concern practical measures aimed at eliminating the Nazi regime, primarily the identification and punishment of war criminals. It was much more difficult with the ideology of Nazism, which had penetrated deeply into German society. The problem was also the initial lack of understanding of its content and role in the formation of a totalitarian regime. The war had showed what a real threat to humanity the ideas and designs of German fascism, striving for world domination, posed. During the occupation period, the Allies had to rebuild the education system, upbringing, culture, social relations, and social life of the Germans. The ambiguity of approaches, which took place in the policy of all the occupation authorities in Germany, nevertheless showed us that the main tasks of denazification were indeed solved. However, the process of “overcoming the totalitarian pastˮ did not end there and had its continuation in the German history of the second half of the 20th century.

What are the minimal criteria of goal-directed perfusion (GDP) in adult cardiac surgery?

Introduction: Nowadays, many cardiac surgery teams are adopting the goal-directed perfusion (GDP) strategy in their practice to maintain optimal perfusion during cardiac surgeries and improve patient outcomes. Furthermore, it plays an indispensable role as a quality control tool to monitor both perfusionists’ practice and equipment (in addition to disposables used in the surgery. Objectives: To identify the role and the elements of GDP that facilitate better surgical outcomes. In addition, to compare between GDP and the traditional conventional perfusion strategy (CP) in terms of perfusion adequacy and surgical outcomes. Finally, to recognize challenges that may prevent the effective application of GDP and finding possible applicable solutions. Methods: A systematic literature review was conducted from three different databases PubMed, SpringerLink, and ScienceDirect. The selected studies were in English from the USA and Europe with a time frame starting from 2005. Results: The findings highlight the crucial role of the GDP strategy in protecting and preserving end-organ function after on-bypass cardiac surgery procedures. Furthermore, a clear understanding of the GDP implementation component and criteria was obtained. Alternatively, a satisfactory GDP level can be achieved by the optimal utilization of available resources. Discussion: Dismantling the GDP strategy into practically recognized components to ease the implementation at different levels of perfusion practice. Conclusion: The GDP approach involves the intensive monitoring of respiratory-related parameters to enhance surgical outcomes. The process includes blood preservation, optimal flow and intraoperative parameters management. Monitoring is the key element of GDP, which can be applied by using the sophisticated technology or the proper use of existing resources to develop protocols within the international guidelines and recommendations. Achieving an optimal perfusion requires concerted efforts of organizational, safety, and practical measurements.

Evaluation of sampling methods of Diaphorina citri Kuwayama (Hemiptera: Liviidae) in two citrus growing areas

Efficient, easy to implement and low-cost monitoring methodologies are necessary to obtain information on arthropod pest populations and to implement the most convenient and timely phytosanitary control practices. To optimize the sampling and monitoring of the Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae), an insect associated with the transmission of Candidatus Liberibacter asiaticus and Ca. L. americanus, which cause Huanglongbing (HLB), a disease with a great impact on citrus orchards, three methods of adult sampling (yellow sticky traps, sweep net, and stem tap) were evaluated. For immature sampling, vegetative shoots were checked. The results demonstrate that the population density at the time of sampling affects the effectiveness and sensitivity of the sampling methods. Yellow sticky traps capture more adults and are the only effective method at low psyllid densities. Stem tap and sweep net are less expensive methods; however, they do not detect adults nor correlate with the number of nymphs and eggs in vegetative shoots when adult density is low. For adults, an optimal sample size was determined for each method. For yellow sticky traps, 3 to 5 traps for a 2-hectare plot with weekly frequency are recommended. For immatures, it is recommended to estimate the percentage of infestation by inspecting 45 to 55 vegetative shoots well-distributed within a 2-hectare plot, as a practical measure for farmers and extensionists to monitor D. citri.

Effect of Cultural Heritage on Tourism Development in Italy

Purpose: The aim of the study was to analyze the effect of cultural heritage on tourism development in Italy. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: The cultural heritage of Italy plays a significant role in its tourism development, attracting millions of visitors annually to historic cities like Rome, Florence, and Venice. Italy's rich history, art, architecture, and traditions make it a global cultural destination, with UNESCO World Heritage Sites such as the Colosseum, the Vatican, and the Uffizi Gallery serving as major draws. This cultural wealth not only boosts the tourism industry but also supports local economies and preserves historical landmarks. Unique Contribution to Theory, Practice and Policy: Cultural capital theory, sustainable tourism theory & heritage conservation theory may be used to anchor future studies on the effect of cultural heritage on tourism development in Italy. Implementing practical measures such as visitor quotas, dynamic pricing, and timed entry tickets can help regulate tourist flow to high-traffic cultural heritage sites. Policymakers should develop sustainable tourism frameworks that balance economic growth with cultural heritage preservation.

Adoption of quick response codes as a digital microlearning tool among clinical nurses: a quasi-experimental study.

The rapid growth of technology forced enormous changes in the provision of healthcare services. Different strategies are used to keep nurses up to date with rapid changes in health systems. Microlearning is one of the new methods of teaching professional skills to health workers. This method is effective in care settings that have many limitations in terms of time and place. However, it is very important to test the acceptability of this method among nurses before practical measures are taken for its widespread use. This study aimed to determine nurses' acceptance rate of quick response code as a microlearning tool in workplace. This is a cross-sectional study was conducted in medical and surgical wards in hospitals affiliated to Guilan University of Medical Sciences. 185 nurses participated in the study. A number of selected medical devices were labeled with quick response codes containing educational content. The eligible nurses were instructed how to use the QR codes. After two months, they were asked to complete a questionnaire adapted from the technology acceptance model 3. SPSS 21 software was used to analyze the data. 166 nurses and 19 head nurses with mean age of 34.26 ± 8.17 years and mean work experience of 10.46 ± 7.64 years completed the questionnaires. Most participants were female, married, with a bachelor's degree, worked on rotating shifts, in medical wards. The findings showed that the acceptance of the quick response code as a learning tool was at a moderate level (M = 66.1, SD = 16.6). Statistically, there was no significant relationship between nurses' demographic characteristics and the total acceptance rate (P > 0.05). However, the analyses at the multivariate level, using multiple linear regression, showed a significant superiority of the total acceptance score in head nurses compared to nurses (b = 7.97, P = 0.047) and in nurses who had previous experience of using quick response codes, compared to colleagues without such experience (b = 5.18, P = 0.036). Based on the coefficient of determination, only 6.1% of the changes in the total acceptance score of quick response codes of nurses are explained by their personal-occupational characteristics (R2 = 0.061). The provision of QR code requirements such as necessary infrastructure and training by the health authorities could increase the acceptance of this tool as a microlearning measure.

Forecasting Suitable Habitats of the Clouded Leopard (Neofelis nebulosa) in Asia: Insights into the Present and Future Climate Projections Within and Beyond Extant Boundaries

Terrestrial carnivores, such as the clouded leopard (Neofelis nebulosa), are ‘vulnerable’ and experiencing significant population declines in mainland Asia. Considering the assessed threats, the IUCN has repetitively revised the range of this felid and now characterized it into four distinct categories (extant, possibly extant, possibly extinct, and extinct). Although several ecological works have been accomplished on this enigmatic carnivore, the overall view of its habitat suitability, fragmentation, and corridor connectivity in both present and historical ranges is lacking. Thus, achieving this ecological information under present and future climate scenarios is crucial. The model identified merely 44,033 sq. km falling within the extant range (representing 31.66%) and 20,034 sq. km (8.13%) in the possibly extant range. Fascinatingly, within the historical ranges, an additional 15,264 sq. km (6.58%) has been identified as suitable habitat in the possibly extinct range and 14,022 sq. km (2.38%) in the extinct range. Notably, a total of 25,614 sq. km of suitable habitat is found within designated protected areas across the entire range. Nevertheless, climate change is expected to drive habitat loss of up to 41% (overall IUCN range) for N. nebulosa in both present and historical extent, with habitat patches becoming increasingly fragmented. This is reflected in a projected decline in the number of viable habitat patches (NP) by up to 23.29% in the future. This study also identified 18 transboundary biological corridors for N. nebulosa, with Southeast Asian countries expected to experience the most significant declines in corridor connectivity. In contrast, the South Asian countries (Bhutan, Nepal, and India) are projected to maintain relatively higher connectivity in the future. Nevertheless, a substantial decline in overall mean corridor connectivity is projected in the near future due to the impacts of climate change. This study underscores the urgent need for a coordinated and multifaceted conservation strategy for N. nebulosa, focusing on mitigating habitat loss and fragmentation. Practical measures must be implemented to protect the species’ shrinking range, considering its declining corridor networks and heightened vulnerability to inbreeding depression. Moreover, the assessment of habitat suitability both within and beyond the extant range, alongside corridor connectivity measures, provides valuable insights into potential translocation and reintroduction sites for this species. These findings provide a critical foundation for developing a strategic conservation plan tailored to the specific needs of this felid species across South and Southeast Asia, ensuring enhanced climate resilience and mitigating associated threats.

Study on the predictive model of delirium risk after surgery for elderly hip fractures based on meta-analysis.

To develop and validate a risk prediction model for postoperative delirium in elderly patients with hip fractures, aiming to identify high-risk patients and implement preventive measures. A systematic search of five authoritative medical databases was conducted, retrieving a total of 1368 relevant articles. After screening, 44 high-quality studies were included in the meta-analysis, analyzing 13 potential risk factors, such as age, gender, diabetes, and history of stroke. A risk prediction model was constructed and validated in a cohort of 189 elderly hip fracture patients. The model's predictive performance was evaluated using ROC curves, with calibration assessed through the Hosmer-Lemeshow test, and clinical utility examined via Decision Curve Analysis (DCA) and Clinical Impact Curves (CIC). The meta-analysis identified the following as independent risk factors for postoperative delirium: age (≥ 70years), male gender, diabetes, history of stroke, preoperative comorbidities (≥ 2), previous delirium, preoperative cognitive impairment, low preoperative albumin levels (≤ 40g/L), prolonged preoperative waiting time (≥ 48h), anemia (≤ 100g/L), ASA classification (≥ 3), use of general anesthesia, and prolonged surgery duration (≥ 2h). The prediction model demonstrated strong efficiency in the validation cohort, with an AUC of 0.956, sensitivity of 87.3%, specificity of 94.8%, and a Brier score of 0.144, indicating high predictive accuracy and calibration. DCA and CIC analyses showed the model to have strong clinical decision-making value and impact across most thresholds. The risk prediction model developed in this study shows high predictive accuracy and clinical utility, making it valuable for identifying high-risk patients and implementing preventive measures in clinical practice. However, the study has limitations, such as potential retrospective bias, and further validation in larger, multicenter prospective studies is needed to confirm the model's broader applicability and stability.

POLICY DEVELOPMENT FOR EFFECTIVE SCHOOL MANAGEMENT AMIDST DETERIORATING DISCIPLINE IN SECONDARY SCHOOLS IN KWAZULU-NATAL: CHALLENGES AND STRATEGIES

The current increasing indiscipline in the secondary schools undermines the overall management of schools hence the importance of proper school management for the achievement of the set objectives is critical important(Daka, 2021). Another problem that has come to light is eroding discipline among students in KwaZulu-Natal, South Africa: the issues under the management of misbehaviour disrupt school administration and jeopardize the educational process. In this paper, I discuss the numerous multifaceted causes of the difficulties that current secondary schools encounter in establishing discipline. Through a review of literature, coupled with interviews with educational administrators personally encountered by the researcher, important areas of consideration, among which include the socio-economic conditions, poor school policies, and a bad influence from the community have been found to be among the important factors that contribute to the current disciplinary crisis. The study employs Bronfenbrenner’s Ecological Systems Theory as a framework to analyse the interconnected systems influencing school discipline, including the microsystem (family and school environments), mesosystem (interactions between school and community), exosystem (external policies and socio-economic conditions), and macrosystem (cultural and societal norms). The findings highlight the need for comprehensive and multi-faceted strategies to address these challenges effectively. Some of the key suggestions include providing practical, effective and clear disciplinary measures to be taken, enhancing school community relations, and providing teachers with training and focusing on the socio-economic factors leading to indiscipline. The study also highlights the practical recommendation as ethical leadership and inclusion of the African philosophy, specifically Ubuntu, in developing the better-discipline school climate. This study provides a valuable contribution to the literature on educational management in South and provides practical research that may be useful for policymakers, educators, and school administrators who want to improve school discipline and management. The strategies put forward present an opportunity for schools in KwaZulu-Natal to foster appropriate environment that would facilitate learning and ensure that learners gain improved education outcomes, and instil discipline insisting on accountability among llearners.

Current Situation of Heat Stress Studies on Kendo Players: A Scoping Review

Background/Objectives: Global warming and the rise in the average temperature in recent years have increased the risk of heat stroke and also deteriorated performance among athletes. Kendo, a traditional Japanese martial art and also a competitive sport, is reported to have high incidents of heat stroke and related mortality. However, there is no heat management guideline for this specific sport to date and research on its heat management practices and risk factors for heat stroke are limited. The present study conducted a scoping review on studies focused on heat stress and the heat management practices of Kendo players. Methods: A literature search was conducted using five databases (PubMed, SCOPUS, Ichu-shi Web, CiNii, and Google Scholar) and also manually from the references of searched articles. Results: Overall, the studies that have investigated the heat stress of Kendo players are scarce and outdated. Of the 15 references that met screening criteria, 11 studies were conducted in a field setting. The vast majority were conducted on male university students and there was a lack of research on females and on different age groups. Common measures of heat management practices used in previous studies were weight changes before and after training (n = 14), body temperature (n = 9), and heart rate (n = 8). Only a few studies used multiple measures to determine heat stress. Conclusions: Considering the continuation of global warming and the increasing risk of heat stroke, further investigation on heat stress, its association with health and performance, and current heat management practices in Kendo players are warranted.

Exercise intensity measurement using fractal analysis of heart rate variability: Reliability, agreement and influence of sex and cardiorespiratory fitness

ABSTRACT The study aimed to establish the test-retest reliability of detrended fluctuation analysis of heart rate variability (DFA-α1) based exercise intensity thresholds, assess its agreement with ventilatory- and lactate-derived thresholds and the moderating effect of sex and cardiorespiratory fitness (CRF) on the agreement. Intensity thresholds for thirty-seven participants (17 females) based on blood lactate (LT1/LT2), gas-exchange (VT1/VT2) and DFA-α1 (αTh1/αTh2) were assessed. Heart rate (HR) at αTh1 and αTh2 showed good test-retest reliability (coefficient of variation [CV] < 6%), and moderate to high agreement with LTs (r = 0.40 – 0.57) and VTs (r = 0.61 – 0.66) respectively. Mixed effects models indicated bias magnitude depended on CRF, with DFA-α1 overestimating thresholds versus VTs for lower fitness levels (speed at VT1 <8.5 km⋅hr−1), while underestimating for higher fitness levels (speed at VT2 >15 km⋅hr−1; VO2max >55 mL·kg−1·min−1). Controlling for CRF, sex significantly affected bias magnitude only at first threshold, with males having higher mean bias (+2.41 bpm) than females (−1.26 bpm). DFA-α1 thresholds are practical and reliable intensity measures, however it is unclear if they accurately represent LTs/VTs from the observed limits of agreement and unexplained variance. To optimise DFA-α1 threshold estimation across different populations, bias should be corrected based on sex and CRF.

Perceptions of forensic interviewers on the sexual education of individuals with a disability exposed to sexual victimisation

ABSTRACT This qualitative study examines the perspectives of forensic interviewers on the education of individuals with a disability who have been exposed to sexual abuse and violence. Data were collected through semi-structured interviews with 25 forensic interviewees in six provinces in Turkey. The data were analysed using thematic analysis. Thematic analysis results revealed four themes: types of disabilities of individuals subjected to sexual violence and abuse; family; education and sexual violence and abuse; and the effect of difficulties in self-expression during the forensic interview process. The findings emphasise the necessity for tailored, visually supported education aligned with developmental stages to prevent sexual violence. The inclusion of parents in these sexual education sessions could prove to be effective in preventing the onset of sexual abuse perpetrated against individuals with a disability. The insights provided by forensic interviewers underscore the importance of an interdisciplinary approach in developing and implementing sexual education programmes, aiming to address deficiencies in current sexual education frameworks. Personal safety and sexual education could be useful in preventing negative incidents that individuals with a disability may encounter at every stage of their lives. PRACTICE IMPACT STATEMENT Our results highlight the critical importance of customised sexual education programmes for reducing the vulnerability of individuals with a disability to sexual violence and abuse. It addresses the role of identifying practical measures to address the risks associated with these individuals, promoting parental involvement, and raising awareness in the community. Interdisciplinary collaboration across various fields, such as health care, psychology, and law, and the development of inclusive sexual education initiatives, may be important for protecting the rights and well-being of individuals with a disability and their families.

Measurement and analysis of photoacoustic pressure induced by weak microsecond pulsed light

The photoacoustic effect (PAE) of weak microsecond pulsed light (WMPL) has immense potential for application to biomedical engineering. However, practical measurements and theoretical analysis of the photoacoustic pressure of WMPL are lacking. Hence, we constructed a WMPL photoacoustic pressure measurement system using an electret piezoelectric sensor and multi-wavelength parameter-adjustable pulsed light generator. Based on the system, the photoacoustic pressure interacting with the air medium induced by the WMPL with different optical parameters was measured. The measured pressure data were analyzed using the fixed variable method, and the pressure response characteristic was obtained. It was found that the measured results conform to the law of energy conversion but have a specific trend for some wavelengths. The analysis and discussion were conducted based on the classical wave equation of the PAE, and the extended wave equation was presented. It is shown that the proposed approach provides a reliable basis for the measurement and analysis of WMPL photoacoustic pressure.

Lessons to learn for better safeguarding of genetic resources during tree pandemics: The case of ash dieback in Europe

Ash dieback (ADB) has been threatening populations of European ash (Fraxinus excelsior & F. angustifolia) for more than three decades. Although much knowledge has been gathered in the recent past, practical conservation measures have been mostly implemented at local scale. Since range contraction in both ash species is likely to be exacerbated already in the near future by westward expansion of the emerald ash borer and climate change, systematic conservation frameworks need to be developed to avoid long-term population-genetic consequences and depletion of genomic diversity. In this article, we address the advantages and obstacles of conservation approaches aiming to conserve genetic diversity in situ or ex situ during tree pandemics. We are reviewing 47 studies which were published on ash dieback to unravel three important dimensions of ongoing conservation approaches or perceived conservation problems: i) conservation philosophy (i.e. natural selection, resistance breeding or genetic conservation), ii) the spatial scale (ecosystem, country, continent), and iii) the integration of genetic safety margins in conservation planning. Although nearly equal proportions of the reviewed studies mention breeding or active conservation as possible long-term solutions, only 17 % consider that additional threats exist which may further reduce genetic diversity in both ash species. We also identify and discuss several knowledge gaps and limitations which may have limited the initiation of conservation projects at national and international level so far. Finally, we demonstrate that there is not much time left for filling these gaps, because European-wide forest health monitoring data indicates a significant decline of ash populations in the last 5 years.

Therapeutic approaches and conceptions of practice of osteopaths in Australia - a national cross-sectional study and exploratory factor analysis of the Osteo-TAQ

BackgroundHealth professionals develop their own approach to patient care based on education, experience and philosophical stance. Literature suggests that this practice approach informs patient care, and clinical outcomes. The Osteopaths’ Therapeutic Approaches Questionnaire (Osteo-TAQ) is a novel 36-item instrument developed from qualitative grounded theory research with osteopaths in the United Kingdom. The aim of the study was to develop evidence for the structural and construct validity of the Osteo-TAQ in the Australian osteopathic profession and provide initial descriptive data about the therapeutic approaches of osteopaths in Australia.MethodsA cross-sectional study design was used to collect data from registered osteopaths in Australia using the Osteo-TAQ and analysed with Exploratory Factor Analysis (EFA). The EFA utilised parallel analysis to determine the number of factors to extract and McDonald’s omega calculated as the reliability estimation statistic.Results691 Australian osteopaths provided data for the study, representing 25% of the Australian osteopathic profession. Empirically the number of factors to extract based on the parallel analysis was seven. Two- and three-factor solutions were evaluated given the underpinning theory identifying two conceptions of practice and three interrelated therapeutic approaches. Both the two- and three-factor solutions were consistent with the underpinning theory with acceptable reliability estimations for each factor. Descriptive data suggested the most common element of the therapeutic approach of Australian osteopaths was establishing rapport, while the least common was ‘only talking’ with their patients.ConclusionsThis study provides evidence for the structural, content and construct validity of the Osteo-TAQ in an Australian osteopathic practitioner population. The results support both a two- and three-factor structure for the Osteo-TAQ in an Australian osteopathic population, with each factor demonstrating acceptable reliability estimations supporting the items comprising each factor as measuring a single construct. From a theoretical and empirical perspective, it can be inferred that the Osteo-TAQ tool encapsulates an osteopaths’ conception of practice (professional artistry and technical rational) and three main therapeutic approaches to patient care: Educator, Communicator and Treater. Further research is required to explore each of these therapeutic approaches to better understand how they relate to an individual osteopath’s conception of practice, and their associations with other measures of practice including clinical outcomes.

Establishment of Evidence-Based Nursing Indices for Dysphagia After Anterior Cervical Spine Surgery.

To select and obtain relevant evidence for the management of dysphagia after anterior cervical spine surgery both domestically and internationally, clinical quality evaluation indicators were developed based on evidence-based nursing practices, and obstacles and promoting factors in evidence-based nursing practices were analysed. This research was aimed to provide a basis for evidence-based nursing practices to promote standardized management of dysphagia after anterior cervical surgery. Dysphagia is the most common complication following anterior cervical surgery, but there is a lack of standard protocols and guidelines to direct clinical practice. Mixed methods were employed for the translational research to support evidence-based practice. This study was based on the JBI evidence-based health care model. According to the '6S Evidence Resource Pyramid Model', we searched from top to bottom. This study is guided by the knowledge to action (KTA) evidence-based practice model. Utilizing a comprehensive evidence-based approach and following the 6S evidence resource pyramid model, relevant evidence on the management of swallowing disorders after cervical anterior surgery was selected from both domestic and international sources. Based on the best available evidence, the Delphi expert consultation method was used to establish a management plan for swallowing disorders post-cervical anterior surgery. Semi-structured interviews were then conducted to identify barriers to clinical implementation, and clinical quality evaluation indicators, as well as promoting factors, were subsequently developed. Based on the 31 best evidence points, 12 evaluation indicators were developed. The baseline results of these indicators reveal that, apart from evaluation indicator 8, which has a compliance rate of 72.2%, the compliance rates for most of the other indicators are relatively low. Based on the results of the clinical quality review, the following main obstacles were analysed: negative behaviours and attributes, lack of professional knowledge, and lack of standardized management. Effective management of swallowing disorders after cervical spine surgery is crucial for enhancing treatment outcomes, reducing complications, shortening hospital stays and improving patient quality of life. This study identified the best evidence for managing dysphagia post-anterior cervical surgery and developed corresponding solutions. The next step involves applying these measures in clinical practice to improve patient prognosis and elevate the quality of care.
