The association between school burnout, school connectedness, and bullying victimization: A longitudinal study

Despite the importance of school connectedness and bullying victimization in students’ school burnout, to our knowledge, very few studies have analyzed their reciprocal associations, and most of them have used cross-sectional designs. So, the nature and directions of these relations have not been established yet. The general aim of this study was to address this gap by testing a longitudinal model of the association between the mentioned variables in a group of Italian students. The participants are 363 students from Italian secondary schools (34% females; Mage = 13.35, SD = 1.47), who took part in three waves of data collection. One hundred and eighty-four students attended middle school (45% females; Mage = 12.01, SD = 0.46), and 179 students attended high school (22% females; Mage = 14.62, SD = 0.836). The adolescents filled out a questionnaire containing self-report measurements of studied variables three times, with an interval of 6 months. At both school levels, the results show the reciprocal and longitudinal role of school connectedness in reducing burnout, and of school burnout in reducing the sense of connectedness to school, both directly and indirectly. On the contrary, bullying victimization is not longitudinally associated with school burnout, whereas it negatively predicts the level of students’ connectedness to school. The study findings have revealed the importance of considering longitudinal and reciprocal associations among school burnout, connectedness, and bullying victimization, and are discussed referring to their implications for research and intervention efforts aimed at promoting students’ school well-being.
On the permeability of colloidal gels

We reexamine and refine analytical theories for permeability in colloidal networks, with particular focus on constants and identification of approximations. The new theories are compared against numerical simulations of Stokes flow through the networks and reveal nearly quantitative power-law predictions for both pore size and permeability at low volume fractions, with systematic deviations observed only at high volume fractions. Comparison with two previously published experimental data sets yields mixed results: in one case, very good agreement is found, while in the other, only the scaling is correctly predicted. In fractal gel networks, the permeability is commonly modeled as a power-law function of volume fraction, with the fractal dimension of the network determining the power-law exponent. To quantitatively probe the influence of gel structure on permeability, we investigate this relation in structures generated by diffusion-limited cluster aggregation (DLCA) and reaction-limited cluster aggregation (RLCA) and, for contrast, non-overlapping uniform random dispersions of particles. Geometric analyses are used to determine network pore size distributions, fractal dimensions, and percolation characteristics. High-fidelity simulations of the slow viscous flow of Newtonian fluids are used to obtain first-principles-based velocity and fields and hence network permeabilities. Interestingly, the effective pore size that determines permeability is found to be somewhat larger than that measured by a method based on the insertion of spherical probes. Empirical inclusion of a fractal dimension dependence on volume fraction is found to yield quantitative results for permeabilities over the entire volume fraction range studied, in both DLCA and RLCA materials.We reexamine and refine analytical theories for permeability in colloidal networks, with particular focus on constants and identification of approximations.

Encouraging social diffusion of pro‐environmental behavior through online workshop‐based interventions

Motivating people to take environmentally friendly action, especially collective actions that promote greater social engagement, is important for addressing environmental issues like biodiversity loss. We conducted an online workshop‐based field experiment to target social‐psychological perceptions to motivate people to plant native plants and encourage others to do the same. To shift these perceptions, we added 13 microinterventions to half the workshops, including normative messaging, public commitment‐making, and providing feedback on the impact of reaching out to others. We used a voucher system to track real‐world behavior by partnering with native plant nurseries. Compared to an information‐only control workshop, our intervention workshops initially increased certain social‐psychological perceptions related to encouraging others to plant native plants. However, they did not change behaviors, or many perceptions, compared to control workshops. Additional exploratory analyses revealed differing patterns of behavioral perceptions 2 months after the workshops. Further research is needed that implements experimental methods and real‐world measures of conservation behavior to evaluate the impacts of theory‐based outreach tactics on collective actions.
Recovery operators, paraconsistency and duality

There are two foundational, but not fully developed, ideas in paraconsistency, namely, the duality between paraconsistent and intuitionistic paradigms, and the introduction of logical operators that express metalogical notions in the object language. The aim of this paper is to show how these two ideas can be adequately accomplished by the logics of formal inconsistency (LFIs) and by the logics of formal undeterminedness (LFUs). LFIs recover the validity of the principle of explosion in a paraconsistent scenario, while LFUs recover the validity of the principle of excluded middle in a paracomplete scenario. We introduce definitions of duality between inference rules and connectives that allow comparing rules and connectives that belong to different logics. Two formal systems are studied, the logics mbC and mbD, that display the duality between paraconsistency and paracompleteness as a duality between inference rules added to a common core—in the case studied here, this common core is classical positive propositional logic. The logics mbC and mbD are equipped with recovery operators that restore classical logic for, respectively, consistent and determined propositions. These two logics are then combined obtaining a pair of LFI and undeterminedness, namely, mbCD and mbCDE. The logic mbCDE exhibits some nice duality properties. Besides, it is simultaneously paraconsistent and paracomplete, and able to recover the principles of excluded middle and explosion one at a time. The last sections offer an algebraic account for such logics by adapting the swap structures semantics framework of the LFIs the LFUs. This semantics highlights some subtle aspects of these logics, and allows us to prove decidability by means of finite nondeterministic matrices.
The Szeletian and the Transition from Middle to Upper Palaeolithic in Central Europe

This book concerns one aspect of the transition from the middle to the upper Palaeolithic in Europe about 40,000 years ago when Neanderthal man was succeded by anatomically modern man. It relates to the Szeletian, named after the cave of Szeletia in Hungary, an archaelogical entity characteristic of that period in Central Europe. The author reaches the conclusion that the Szeletian was the creation of Neanderthal man and that together with its creator it was replaced by the Aurignacian and by anatomically modern man. An extensive database is provided in this volume which also contains 50 plates or original drawings and 20 photographs of the major sites.
The Role of Stereotactic Radiotherapy for the Treatment of Melanoma and Renal Cell Carcinoma Brain Metastases

OBJECTIVE The best radiotherapeutic approach for brain metastasis (BM) is highly controversial. Compared to Whole-brain radiotherapy, the stereotactic radiotherapy (SRT) technique allows for focused ablative doses to target lesions. We aim to present our clinical experience with SRT as a treatment option for radioresistant BM in melanoma and renal cell carcinoma (RCC)
Reemission of inorganic pollution from permafrost? A freshwater hydrochemistry study in the lower Kolyma basin (North‐East Siberia)

Permafrost regions are under particular pressure from climate change resulting in widespread landscape changes, which impact also freshwater chemistry. We investigated a snapshot of hydrochemistry in various freshwater environments in the lower Kolyma river basin (North‐East Siberia, continuous permafrost zone) to explore the mobility of metals, metalloids and non‐metals resulting from permafrost thaw. Particular attention was focused on heavy metals as contaminants potentially released from the secondary source in the permafrozen Yedoma complex. Permafrost creeks represented the Mg‐Ca‐Na‐HCO3‐Cl‐SO4 ionic water type (with mineralisation in the range 600–800 mg L−1), while permafrost ice and thermokarst lake waters were the HCO3‐Ca‐Mg type. Multiple heavy metals (As, Cu, Co, Mn and Ni) showed much higher dissolved phase concentrations in permafrost creeks and ice than in Kolyma and its tributaries, and only in the permafrost samples and one Kolyma tributary we have detected dissolved Ti. In thermokarst lakes, several metal and metalloid dissolved concentrations increased with water depth (Fe, Mn, Ni and Zn – in both lakes; Al, Cu, K, Sb, Sr and Pb in either lake), reaching 1370 μg L−1 Cu, 4610 μg L−1 Mn, and 687 μg L−1 Zn in the bottom water layers. Permafrost‐related waters were also enriched in dissolved phosphorus (up to 512 μg L−1 in Yedoma‐fed creeks). The impact of permafrost thaw on river and lake water chemistry is a complex problem which needs to be considered both in the context of legacy permafrost shrinkage and the interference of the deepening active layer with newly deposited anthropogenic contaminants.
HOMESTAY PROGRAMME AS A MALAYSIAN TOURISM PRODUCT

This book discusses the homestay programme in Malaysia in the context of tourism product.It begins by looking into the evolution of tourism in Malaysia, focusing on its growth and development.Tourism product is an important component of any tourism destination, thus the book later looks into the product concept as well as the development of tourism products in Malaysia.Malaysia has many natural, cultural and man-made tourist products and attractions that can potentially pull tourists to its shore.The rest of the book then turns into the discussion of the Malaysian homestay programme.The programme, which can be categorized as Malaysia’s rural cultural tourism product may well be a way to reinvigorate tourism as it is an initiative to attract alternative tourist markets due to its unique product elements.Different perspectives and conceptual frameworks are used in looking at the homestay programme specifically in the area of product benefits, tourist experience, resident perceptions, and product quality. The elements of the programme are identified and the outcomes explored.Finally, issues surrounding the programme are discussed and recommendations on future management of the programme are offered. The book is hoped to answer enquiries about the unique homestay programme in Malaysia, if not completely, at least partially.
Prognostic value of C-reactive protein-to-albumin ratio in acute pancreatitis: a systematic review and meta-analysis

Background: Acute pancreatitis (AP) is a common disorder and although most of the cases are mild, the mortality risk is high when it comes to severe AP. It is therefore important to determine the severity of AP as early as possible. This review aimed to determine the prognostic value of C-reactive protein-to-albumin ratio (CRP/alb ratio) in patients with AP. Methods: We performed a systematic search on the electronic databases PubMed, Science Direct, and Cochrane Library up to January 2023. Studies reporting CRP/alb ratio on admission and its association with severity or mortality in AP patients were included. We calculated pooled mean difference (MD) and their 95% confidence intervals (CI) using a random-effects model. Quality assessment of the included studies was appraised using a Newcastle–Ottawa scale. Results: A total of six studies comprising 2244 patients were included in this meta-analysis. Severe AP had higher CRP/alb ratio on admission than mild-moderate AP (pooled MD: 3.59; 95% CI: 2.51-4.68; p<0.00001). CRP/alb ratio was also significantly higher on non-survivor AP patients compared to survivor AP patients (pooled MD: 2.12; 95% CI: 0.43-3.8; p < 0.01). Conclusion: High CRP/alb ratio can be used as an early predictor of poor prognosis in patients with AP.
Iranian Journal of Fuzzy Systems

‘Information Overload’is not a new term but with the massive development in technology which enables anytime, anywhere, easy and unlimited access; participation & publishing of information has consequently escalated its impact. Assisting users‘informational searches with reduced reading surfing time by extracting and evaluating accurate, authentic & relevant information are the primary concerns in the present milieu. Automatic text summarization is the process of condensing an original document into shorter form to create smaller, compact version from the abundant information that is available, preserving the content & meaning such that it meets the needs of the user. Though many summarization techniques have been proposed but there are no ‘silver bullets’to achieve the superlative results as of human generated summaries. Thus, the domain of text summarization is an active and dynamic field of study, practice & research with the continuous need to expound novel techniques for achieving comparable & effectual results. Fuzzy logic has appeared as a powerful theoretical framework for studying human reasoning and its application has been explored within the domain of text summarization in the past few years. This paper is a systematic literature review to gather, analyze, and report the trends, gaps and prospects of using fuzzy logic for automatic text summarization on the basis of the findings in original studies.
Characteristics of Xerosis, Pruritus, and Pallor in Stage 5 Chronic Kidney Disease Patients Undergoing Hemodialysis at Dr. Hasan Sadikin General Hospital, Bandung

Purpose This study aims to delineate the demographic and clinical characteristics of xerosis, pruritus, and pallor among patients with stage 5 chronic kidney disease (CKD) undergoing hemodialysis at Dr. Hasan Sadikin General Hospital, Bandung. Patients and Methods This cross-sectional, descriptive study involved the analysis of 139 selected medical records of patients with stage 5 CKD who underwent hemodialysis between July and August 2022. A comprehensive examination was conducted by a dermatovenereologist, and the findings were duly recorded in the patients’ medical records. The documentation encompassed gender, age, employment status, as well as the clinical characteristics of xerosis, pruritus, and pallor. The collected data were analyzed using descriptive statistical methods. Results Out of the 139 patients, 70 (50.4%) were male, while 69 (49.6%) were female. The mean (SD) age was 47.6 (11.8) years. The majority of the patients were unemployed (n=96, 69.1%). The median (IQR) duration of hemodialysis was 48 (96.0–24.0) months. The predominant findings were xerosis (n=84, 60.4%) and pallor (n=83, 59.7%), followed by pruritus (n=56, 40.3%). Instances of xerosis were more frequently observed in males, whereas pallor was more prevalent in females. Xerosis and pruritus exhibited higher prevalence in the ≥65 years age group, whereas pallor was more common in the 18–44 years age group. In contrast to xerosis, pruritus and pallor were more frequently noted in the unemployed group. Xerosis was predominantly mild with overall dry skin (ODS) score of one, and it was mainly observed on the patients’ legs. Among those experiencing pruritus, over half displayed a moderate severity with visual analogue scale (VAS) scores ranging from ≥3 to <7. Patients with pallor mostly exhibited hemoglobin levels below 10 g/dL. Conclusion Xerosis, pruritus, and pallor were prevalent among patients with stage 5 CKD undergoing hemodialysis. These disorders presented with distinct demographic and clinical characteristics. Timely diagnosis and intervention have the potential to enhance the quality of life for these patients.
Diffusive-thermal instabilities of a planar premixed flame aligned with a shear flow

The stability of a thick planar premixed flame, propagating steadily in a direction transverse to that of unidirectional shear flow, is studied. A linear stability analysis is carried out in the asymptotic limit of infinitely large activation energy, yielding a dispersion relation. The relation characterises the coupling between Taylor dispersion (or shear-enhanced diffusion) and the flame thermo-diffusive instabilities, in terms of two main parameters, namely, the reactant Lewis number $ {{Le}} $ Le and the flow Peclet number $ {{Pe}} $ Pe. The implications of the dispersion relation are discussed and various flame instabilities are identified and classified in the $ {{Le}} $ Le- $ {{Pe}} $ Pe plane. An important original finding is the demonstration that for values of the Peclet number exceeding a critical value, the classical cellular instability, commonly found for $ {{Le}} \lt 1 $ Le<1, exists now for $ {{Le}} \gt 1 $ Le>1 but is absent when $ {{Le}} \lt 1 $ Le<1. In fact, the cellular instability identified for $ {{Le}} \gt 1 $ Le>1 is shown to occur either through a finite-wavelength stationary bifurcation (also known as type-I $ _s $ s) or through a longwave stationary bifurcation (also known as type-II $ _s $ s). The latter type-II $ _s $ s bifurcation leads in the weakly nonlinear regime to a Kuramoto-Sivashinsky equation, which is determined. As for the oscillatory instability, usually encountered in the absence of Taylor dispersion in $ {{Le}} \gt 1 $ Le>1 mixtures, it is found to be absent if the Peclet number is large enough. The stability findings, which follow from the dispersion relation derived analytically, are complemented and examined numerically for a finite value of the Zeldovich number. The numerical study involves both computations of the eigenvalues of a linear stability boundary-value problem and numerical simulations of the time-dependent governing partial differential equations. The computations are found to be in good qualitative agreement with the analytical predictions.
Late Weichselian and Holocene sedimentary processes and environments in Billefjorden, Svalbard

Three sediment cores, swath multibeam bathymetry data and high-resolution seismic data from Billefjorden, Svalbard have been analysed for a better understanding of the Late Weichselian and Holocene glacier activity as well as sedimentary process and glacigenic deposits in the fjord. The physical properties, sedimentology and mineralogy of the cores were studied. Seven radiocarbon dates provide the basis for the chronology. The occurrence, distribution and relative age of deposition of different morphological features in the fjord were analysed. The sediment cores have been correlated to high-resolution seismic data in order to get a better understanding of the lateral extent of the different lithostratigraphic units. The data reveal that glacial linear features were generated in the central part of Billefjorden while it was filled with ice draining the Svalbard-Barents Sea ice sheet during the Last Glacial. A till in the bottom of a sediment core from the central part of the fjord is inferred to have been deposited before the ice front retreated into Billefjorden around 11230 cal. years BP. An overlying glacimarine unit deposited between c. 11230 and 11200 cal. years BP indicates that the glacier retreated from central parts of the fjord to the fjord head in approximately 30 years. Annual recessional moraines deposited during this period suggest that the glacier front retreated approximately 330 m/ year at the end of the last Glacial. High concentration of shells, low amounts of IRD and XRD results indicate a Holocene climatic optimum between c. 11200 – 7930 cal. years BP in which Nordenskiöldbreen was most likely much smaller than it is at present. XRD results and comparatively high amounts of IRD point to a complex pattern of ice rafting between c. 7930 and 3230 cal. BP. IRD deposited before c. 5470 cal. years BP was most likely transported by sea ice, whereas IRD after 5470 cal. years points towards a growth of Nordenskiöldbreen. The time after c. 3230 is mainly characterised by suppressed rafting of sea ice and icebergs because of the possible presence of multi-year shorefast sea ice during the Neoglacial maximum. Glacial lineations on a bedrock terrace in the inner fjord were formed during a Neoglacial advance of Nordenskiöldbreen. Iceberg ploughmarks and recessional moraines were most likely generated during the retreat after the maximum Neoglacial extent of Nordenskiöldbreen. Mass-transport activity in Billefjorden probably occurred throughout the entire Holocene. There might haven been an increased mass-transport activity shortly after the deglaciation of the fjord, because high rates of isostatic uplift might have caused seismic activity. Other triggering mechanisms include the development of oversteepened slopes by high sediment supply and the pushing of sediments at the grounding line of the glacier. Pockmarks in the central part of the fjord were most likely generated by the seepage of thermogenic gas along the Billefjorden fault zone.
Hausdorff Dimension Estimates for Interconnected Systems With Variable Metrics

In this letter, we develop a framework for estimating the Hausdorff dimension of a compact invariant set for both autonomous and interconnected systems. We first generalize Smith’s method for Hausdorff dimension estimates by using variable metrics in linear matrix inequalities. Then, we study open systems with a characterization similar to the differential dissipativity theory. For linear time-invariant systems, we show that our characterization can be considered as a pure input/output property. This fact would be important because it is independent of internal model representations. Finally, we provide an estimate of the attractor dimension for feedback and interconnected systems. Our estimation is scalable in the sense that the components in an interconnected system can be analyzed independently.
