Examining Course Facilitators’ Perspectives on Online Facilitation for Distance Education

The importance of online learning for delivering academic content in distance education cannot be an understatement. Online learning is not only associated with benefits, but it also comes with some challenges among course facilitators in distance education. This study, therefore, examined course facilitators’ perspectives on online facilitation in distance education within the context of a less developed economy. The study adopted the quantitative approach based on descriptive research design with a sample of 529 course facilitators out of a population of 2,768 using multiple sampling techniques such as stratified and simple random sampling. Data were gathered using a structured questionnaire, and partial least squares structural equation modeling (PLS-SEM) was utilized to analyze the results. Findings from the study revealed that course facilitators had online tools and content knowledge but lacked online lesson presentation skills. Availability of online gadgets significantly predicted functionality and online teaching presentation method. Challenges with online learning, availability and functionality of online gadgets, and online presentation methods significantly predicted online use intention and subsequently influenced online usage for teaching among course facilitators. It was recommended that managers of distance education train and provide technical support as well as online gadgets for course facilitators to effectively implement online education. This study provides new insights into how online gadgets, their functionality, and online presentation methods by course facilitators intricately relate among themselves and finally influence online usage intentions and actual usage of online instruction in the distance education milieu.
The Antibacterial Properties of Polish Honey against Streptococcus mutans—A Causative Agent of Dental Caries

Streptococcus mutans is considered the main pathogen responsible for dental caries, one of the major infectious diseases, affecting more than 4 billion people worldwide. Honey is a natural product with well-known antibacterial potential against several human pathogens. The aim of the study was to evaluate the antibacterial efficacy of Polish honey against S. mutans and analyze the role of some bioactive substances on its antibacterial action. The antibacterial potential of different honey varieties (goldenrod, buckwheat, honeydew, and lime) was analyzed using a microdilution assay. Manuka and artificial honey were used as controls. The content of GOX, hydrogen peroxide, total polyphenols, and antioxidant potential was assayed in honey. The influence of catalase and proteinase K on antibacterial activity as well as antibiofilm action was also determined. The strongest antibacterial activity was observed for buckwheat, honeydew, and manuka honey, which were also characterized by the highest antioxidant activity and polyphenols content. Catalase treatment decreases the antibacterial activity of honey, while proteinase K treatment influences the antibacterial potential of honey slightly less. Obtained results suggest that honey can be a good natural product against S. mutans, and hydrogen peroxide was identified as a crucial contributor to its antimicrobial action.
Silicate mineral authigenesis in the Hutton and NW Hutton fields: implications for sub-surface porosity development

The Hutton and NW Hutton fields occur in highly faulted, rotated block structures in Block 211/27 of the East Shetland Basin, Northern North Sea. Fourteen wells that core Brent Group reservoir from these fields have been studied in order to characterize the relationship between clay mineral authigenesis and porosity modification in the sub-surface. Reservoir sands are present in the depth interval 9000–13 000 ft; the shallowest sandstones are subarkoses, contrasting with the deepest sandstones which are mostly feldspar-deficient quartz arenites. The change in composition is a result of diagenetic feldspar dissolution that takes place over the depth interval of study. Authigenic kaolin group minerals and illite are present over the depth range studied, and both exhibit depth-related increases. Three habits of authigenic kaolin group minerals are observed: ‘expanded-mica’, vermiform kaolinite and blocky dickite. The occurrence of vermiform kaolinite is enhanced in Hutton and the adjacent water zone, and does not occur in abundance below 10 500 ft. This habit formed as a result of syn-depositional meteoric water ingress. Structural models suggest that neither field underwent subsequent meteoric water flushing. At the deeper levels of its occurrence range, vermiform kaolinite shows signs of alteration to blocky dickite. Dickite occurs in both intergranular and grain dissolution pores. A depth-related trend of increasing dickite cementation is strongly linked to increasing K-feldspar dissolution. Enhanced dickite cementation is found adjacent to bed contacts in sandstones within mudstone sequences and in regressive sandbodies close to thick mudstone units. Illite shows a more pronounced depth-related increase across the studied interval. Illite precipitation is also genetically linked with detrital feldspar dissolution and is favoured by diminished pore water flow during deep burial. Authigenic clay distribution is partly controlled by local features such as detrital clay coats, in addition to larger-scale parameters such as primary lithology, facies associations, present burial depth and inferred palaeofluid flow. Intergranular porosity declines with increasing burial depth, while grain dissolution porosity increases with depth from Hutton to the shallow and intermediate depth wells of NW Hutton. Generation of enhanced porosity is not related to the unconformities overlying the Brent Group, but to sub-surface fluid migration pathways. Compaction is not significantly operative over the depth interval 10 000–13 000 ft. By 10 000 ft burial depth, up to 50% of the intergranular volume has been lost by mechanical compaction.
The Association between Perceived Family Financial Stress and Adolescent Suicide Ideation: A Moderated Mediation Model

Nowadays, suicide (especially adolescents’ suicide) has been an increasingly prominent social problem worldwide; suicide ideation, as an important predictor, has been the focus of relevant studies and practices. Against this background, the present study aimed to examine the association between perceived family financial stress and adolescents’ suicidal ideation, as well as the potential roles of depression and parent-child attachment. A sample of 526 junior middle school students was recruited voluntarily to participate in this cross-sectional study, and the results indicated that the prevalence of suicidal ideation among junior high school students was 15.45%; perceived family financial stress was positively associated with suicidal ideation, and depression could significantly mediate this relation; parent–child attachment significantly moderated the mediating effect of depression (in particular, the relation between depression and suicidal ideation); specifically, this relation was stronger among adolescents with lower values of parent–child attachment. These findings could deepen our understanding of the influences of perceived family financial condition and the risky factors of adolescents’ suicidal ideation, which could provide guidance for the prevention and intervention of adolescents’ depression and suicidal ideation.
Rural Poverty profile in Pakistan: Incidence, Severity, and Correlates through Consumption Based Approach

Abstract This study is an attempt to estimate the incidence, severity, depth, and determinants of poverty in Jhang district, Punjab, Pakistan. For this purpose, the data were collected from 1,000 households through a specifically designed questionnaire using multistages sampling technique in all four subdistricts of Jhang district. The study used both income-regression model and logistic regression to assess the impact of demographic and socioeconomic factors on poverty incidence. The results show that 54.3% of households are below the poverty line, including 16% extremely poor. Poverty measures including headcount index, severity, and depth of poverty are worse among the households headed by farmers, daily-wagers, and illiterates. Moreover, the results confirm that the household’s livestock population, landholding, ownership of agricultural land, total assets, and earners per household considerably reduced the poverty incidence in Jhang district. While household size, age of household head, economic dependency ratio, and total dependency ratio significantly increased the level of poverty. The study concludes that demographic and socioeconomic characteristics of the households are of greater importance in alleviating poverty generally in Pakistan but particularly in rural areas. Hence, it is suggested that governments should increase public spending on socioeconomic programs and services with a particular focus on education, women’s empowerment, family planning, employment opportunity, pro-agriculture policies, and equitable distribution of land and wealth to alleviate poverty in rural areas of Pakistan. Further research can be conducted by selecting large sample size and analyzing the household characteristics at the disaggregated level incorporating time variations to develop a more impactful policy framework.
Developing Mixed Matrix Membranes with Good CO2 Separation Performance Based on PEG-Modified UiO-66 MOF and 6FDA-Durene Polyimide

The use of mixed matrix membranes (MMMs) comprising metal–organic frameworks (MOFs) for the separation of CO2 from flue gas has gained recognition as an effective strategy for enhancing gas separation efficiency. When incorporating porous materials like MOFs into a polymeric matrix to create MMMs, the combined characteristics of each constituent typically manifest. Nevertheless, the inadequate dispersion of an inorganic MOF filler within an organic polymer matrix can compromise the compatibility between the filler and matrix. In this context, the aspiration is to develop an MMM that not only exhibits optimal interfacial compatibility between the polymer and filler but also delivers superior gas separation performance, specifically in the efficient extraction of CO2 from flue gas. In this study, we introduce a modification technique involving the grafting of poly(ethylene glycol) diglycidyl ether (PEGDE) onto a UiO-66-NH2 MOF filler (referred to as PEG-MOF), aimed at enhancing its compatibility with the 6FDA-durene matrix. Moreover, the inherent CO2-philic nature of PEGDE is anticipated to enhance the selectivity of CO2 over N2 and CH4. The resultant MMM, incorporating 10 wt% of PEG-MOF loading, exhibits a CO2 permeability of 1671.00 Barrer and a CO2/CH4 selectivity of 22.40. Notably, these values surpass the upper bound reported by Robeson in 2008.
Influence of high fluence heavy ion irradiation on the performance of single crystal diamond detectors

Radiation detectors based on diamond are highly favored for particle physics research due to their superior radiation hardness. In this work, the performance of single crystal diamond detectors under high fluence heavy ion radiation has been investigated. After irradiation by Fe13+ and Xe20+ ion beams with a high particle fluence of 1.2 × 1015 cm-2, the properties of unirradiated and irradiated intrinsic single crystal chemical vapor deposition (CVD) diamond detectors are compared by means of the spectroscopic energy resolution, charge collection efficiency (CCE), mobility-lifetime (μτ) product and time response using a 241Am alpha (α) particle source. The experimental results of the unirradiated sample with respect to I-V dark current levels, showed an ohmic behaviour of the Al and Cr/Au contact, CCE of 100%, fast response with a rise time of 750 ps and a fall time of 600 ps as well as drift velocities of 6.67 × 104 m/s and 4.72 × 104 m/s for holes and electrons respectively. In the case of the irradiated samples, the CCE, μτ product and time response pulse amplitude of holes and electrons were all degraded, indicating that high density trappings for both kinds of carriers were created under the diamond crystal surface and the trapping probability of holes and electrons was equal, which was different from the previous reports in the literature where only higher trapping probability of holes were observed under heavy ions irradiation. In particular, the spectroscopic performance as well as μτ product of holes and electrons in Fe13+ irradiated sample decreased more than those in Xe20+ irradiated sample, which implied that the recombination of electrons and holes increased in Fe13+ irradiated sample with greater penetration depth than that in Xe20+ irradiated sample when radiation fluence was up to 1015 cm-2, despite the lower density of lattice vacancies in Fe13+ irradiated sample. Moreover, the rise time of holes was slightly different, but the drift velocity was basically the same as that of the unirradiated sample, and so was that of the electrons. Anyway, the presented results showed that the diamond detectors irradiated by heavy ions at a high fluence of 1015 cm-2 still retained their good spectroscopic and very fast time response properties.

STATUS OF WALLEYE IN THE GREAT LAKES: CASE STUDIES PREPARED FOR THE 1989 WORKSHOP edited by

This paper describes the current status of walleye (Stizostedion vitreum vitreum) stocks in Lake Superior. Although Lake Superior is oligotrophic with a fisheries comprised primarily of cold-water species, walleye have played an important role in shallow-water areas and embayments. The western Lake Superior stock was lightly exploited until dramatic water quality improvements occurred in 1979. The stock now supports a popular sport fishery in both Wisconsin and Minnesota. The slow growth of this stock may make it extremely vulnerable to overexploitation. Other Wisconsin stocks are found in Kakagon Slough and the Bad River. Both stocks support sport and tribal fisheries and the use of supplemental stocking is being investigated. The three large stocks historically in Ontario waters include Nipigon Bay, Black Bay, and Whitefish Bay. All stocks are depressed and stocking is being used for rehabilitation. Overfishingwas identified as the primary reason for declining Lake Superior walleye abundance. Several potential, but undocumented, adverse impacts from exotic species are noted. Contaminant levels on largerwalleye have exceeded recommended consumption guidelines in several areas. Managers attempting to rehabilitate walleye stocks will have to determine basic population characteristics and identify sources of stress before developing a management plan.
Decreased Follistatin Levels as a Risk of Acute Sarcopenia Marker in Elderly

Background: Acute sarcopenia is an acute muscle loss that has been associated to the frailty and vulnerability of the elderly. Follistatin has been known as a significant marker for sarcopenia, however, studies of follistatin in humans have shown varying results and there have been no studies to date regarding the relationship between follistatin and acute sarcopenia. The aim of this study was to determine changes in follistatin levels as a risk of acute sarcopenia in elderly.Materials and methods: This study was a prospective observational study involving hospitalized elderly. The follistatin level was examined with enzyme-linked immunosorbent assay (ELISA). Meanwhile the determination of acute sarcopenia was done through the measurement of changes in hand grip strength and calf circumference parameters. The data obtained was descriptively analyzed, followed by bivariate and multivariate analysis. A p<0.05 was considered significant.Results: There were 66 subjects in this study. A total of 10 subjects (15.2%) had acute sarcopenia on the 7th day of hospitalization. The cut-off point of decreased follistatin levels was 4.870 with a sensitivity of 82.1% and a specificity of 60%. There was an association between decreased follistatin levels and acute sarcopenia (p=0.01; RR: 6.90; 95% CI: 1.638-29.069). Multivariate analysis results showed that decreased follistatin levels was a significant factor that might influence the occurrence of acute sarcopenia.Conclusion: Since this study showed that decreased follistatin levels might be a risk of acute sarcopenia in the elderly, thus it could be used as a marker of acute sarcopenia, which should be further investigated.Keywords: decreased follistatin levels, acute sarcopenia, elderly
Lightweight Real-Time Detection and Recognition Model of Intraocular Foreign Bodies Fused With a Feature Pyramid Mechanism

Accurate detection of target location and type is crucial for treating ocular trauma caused by foreign bodies intrusion. However, the traditional method of manually marking CT image targets has slow recognition speed and poor detection accuracy, which cannot meet the real-time and accuracy requirements for detecting foreign bodies in clinical diagnosis. To address this issue, we propose a lightweight detection and recognition model based on feature extraction and fusion. Firstly, the normalization-based attention module and the sigmoid linear unit activation function are introduced into the inverted residual block of the backbone network to enhance the model’s attention to salient features and improve the detection accuracy. Then, the path aggregation feature pyramid network is utilized to fuse multiscale features, enabling the information interaction between different levels of the network and enhancing the accuracy foreign bodies classification. In particular, the incorporation of the space-to-depth convolution and convolutional mixing modules into the feature pyramid network significantly reduce the computational overhead while effectively capturing the key semantic features in both space and channel directions, thereby improving the lightweight level of the model. Finally, the location and type information of the foreign intraocular bodies are obtained by this model. The experimental results demonstrate the superior performance of the proposed model in terms of mAP@0.5, accuracy, sensitivity and specificity, achieving 97.2, 93.5, 98.0 and 88.0, respectively. Furthermore, the smaller number of parameters and faster detection time allow the proposed model run in real-time on poorly configured hardware, making it more suitable for clinical applications.
Oral Health-Related Quality of Life in Adult Patients with Depression or Attention Deficit Hyperactivity Disorder (ADHD)

The aim of this cross-sectional study was the evaluation of the oral health-related quality of life (OHRQoL) in patients with depression or attention-deficit/hyperactivity disorder (ADHD) in comparison with a group of mentally healthy individuals. Patients from the Department of Psychiatry and Psychotherapy, University of Leipzig, Germany, were recruited. A healthy comparison group (HC) was recruited from the Department of Cariology, Endodontology and Periodontology. The OHRQoL was assessed using the Oral Health Impact Profile G14 (OHIP G14). Furthermore, a questionnaire regarding oral hygiene behaviour was applied. A total of 141 patients with depression or ADHD (depression n = 94, ADHD n = 47) and 145 HC individuals with a balanced age and gender distribution were surveyed. OHIP G14 median scores were significantly higher in the overall psychiatric patient group compared to HC (5.00 vs. 0.00, p < 0.001). This was also found for the four dimensions of OHIP G14 (p < 0.001). The OHIP G14 sum score of patients with depression and ADHD was comparable (5.00 vs. 6.50, p = 0.302). A significant association among psychiatric patients between smoking, gum bleeding, professional tooth cleaning, oral health education, interdental cleaning, and elevated OHIP scores was found (p < 0.001). In conclusion, patients with depression and adults with ADHD show a reduced OHRQoL. A contradictory association between oral hygiene/oral health behaviour and OHRQoL supports the hypothesis of a changed perception of oral conditions in patients with mental diseases. Interdisciplinary collaboration between psychiatric specialists and dentists should be fostered.
Iron Age Settlement Remains at Great Haddon, Peterborough

Between 1/2/14 and 21/1/15 Oxford Archaeology East undertook an archaeological excavation on the proposed site of a commercial unit at Great Haddon, Peterborough (TL 1481 9415). This followed a trenching evaluation in 2006 and a geophysical survey in 2014. The earliest phase of occupation identified was a Middle Iron Age open settlement, comprising two roundhouses, a stock enclosure and associated pits and postholes. Formalisation of this settlement occurred at some point in the Middle Iron Age when a complex enclosure was dug surrounding a roundhouse and associated occupation features. A later phase of remodelling occurred before the settlement was abandoned during the Late Iron Age. Overall the stratigraphic, artefactual and environmental data recovered from this site have a moderate potential to address a number of local and regional research themes.
The Ensuring Knowledge Continuity for Support of Sustainable Business

Changes in approach of management of organizations to human resource management in generations Y and Z are also a very significant trend. An organization must use all possible stimulation tools to ensure knowledge continuity and to help with effective knowledge sharing between generations and support sustainable business. The goal of this article is to identify the benefits that an organization derives from ensuring knowledge continuity, and to identify the strategic documents of an organization that support it and support sustainable business. Data were obtained using quantitative research within selected Czech companies (n = 207) and qualitative research (8 interviews and one focus group). The results showed that 69.6% of the surveyed organizations ensure the knowledge continuity between generations of employees to some (varying) degree, which is influenced by the existence of a human resources management strategy (56.0%) and of an appropriately set organizational culture strategy (52.7%).
