Habitat classification using convolutional neural networks and multitemporal multispectral aerial imagery

Abstract. The monitoring of threatened habitats is a key objective of European environmental policies. Due to the high cost of current field-based habitat mapping techniques, there is keen interest in proposing solutions that can reduce cost through increased levels of automation. Our study aims to propose a habitat mapping solution that benefits both from the merits of convolutional neural networks (CNNs) for image classification tasks, as well as from the high spatial, spectral, and multitemporal unmanned aerial vehicle image data, which shows great potential for accurate vegetation classification. The proposed CNN-based method uses multitemporal multispectral aerial imagery for the classification of threatened coastal habitats in the Maharees (Ireland) and shows a high level of classification accuracy.
The Characteristics of Three‐Belt Structure of Sub‐MeV Electrons in the Radiation Belts

After the launch of Van Allen Probes, the three‐belt structures of ultra‐relativistic electrons are discovered. In this study, we investigate the three‐belt structures of sub‐MeV electrons, which may form under different mechanism compared with those of ultra‐relativistic electrons and are worth in‐depth analysis. Based on the differential flux data from Magnetic Electron Ion Spectrometer onboard Radiation Belt Storm Probes‐B satellite, we find 54 events, in which two comparable peaks of sub‐MeV electron fluxes and a slot appear where there should be the outer radiation belt. Through the statistical analysis, the three‐belt structures of sub‐MeV electrons are found to be closely related to symmetric H‐component (SYM‐H) and Auroral Electrojet (AE) indices. The 2‐day SYM‐H minimum and AE maximum before the event have a linear trend with the remnant belt and the “second slot” locations. The L‐values of the remnant belt and the “second slot” of different energy electrons decrease as energy increases in general and show interesting characteristics during their temporal evolution. Moreover, the lifetime of the remnant belt of different energy electrons increases as energy increases. We find similarities and differences between sub‐MeV and ultra‐relativistic electrons three‐belt events, which provides a new perspective in three‐belt structure study.
Do eReferral, eWOM, familiarity and cultural distance predict enrollment intention? An application of an artificial intelligence technique

Purpose Little empirical attention has been paid to the effects of electronic word-of-mouth (eWOM), electronic referral (eReferral), familiarity and cultural distance on behavioral outcomes, especially within the context of educational tourism. Based on the social network theory, this paper aims to explore the effects of eReferral, eWOM, familiarity and cultural distance on enrollment intention. Design/methodology/approach Survey data (n = 931) were obtained from educational tourists using a judgmental sampling technique. Linear modeling and artificial intelligence (i.e. artificial neural network [ANN]) techniques were used for training and testing the proposed associations. Findings The results suggest that eReferral, eWOM, familiarity and cultural distance predict intention to enroll both symmetrically (linear modeling) and asymmetrically (ANN). The asymmetric modeling possesses greater predictive validity and relevance. Originality/value This study contributes theoretically and methodologically to the management literature by validating the proposed relationships and deploying contemporary methods such as the ANN. Implications for practice and theory are discussed.
Validation of the extended version of the Dissociative Experiences Scale (DES) in patients diagnosed with substance use disorders

ABSTRACT Background The most extensively used instrument to measure dissociation is the Dissociative Experiences Scale (DES). Recently, an extended version of this instrument was provided, which also measures somatoform symptoms of dissociation. The aim of this study was to examine the component structure and internal consistency of the extended version of the Dissociative Experiences Scale (FDS) in patients diagnosed with substance use disorders (SUD). Methods Principal component analyses (PCAs) were conducted in a large clinical sample of patients diagnosed with SUD (n = 459) for the 44 FDS items, the 28 original DES items, the 23 items of the original DES subscales that compose FDS subscales of amnesia, absorption, and depersonalization/derealization, and the 9 conversion subscale items. Results PCA of all 44 FDS items yielded a 9-factor solution where the first factor explained 32% variance. A 6-, 4-, and 2-factor solution, respectively, was found for 28 DES original items, 23 items of original DES subscales that compose FDS subscales of amnesia, absorption, and depersonalization/derealization, and 9 items of the conversion subscale of the FDS. Conclusion FDS proves to be a reliable tool that can be used to screen patients with SUD for dissociative psychopathology within the ICD and DSM-5 framework.
Growing the Talent Pool: How Sponsorship of Professional Sales Programs Enhances Employer Branding

Increasingly, professional sales programs receive financial support from company sponsors in exchange for varying types of branding and recruiting opportunities. This study builds on the literature regarding employer branding and talent acquisition by examining the effect sales program sponsorship has on students. Grounded in organizational reputation theories, brand equity, and the literature on corporate sponsorship, it is proposed that sponsoring a sales program leads to positive student–firm related perceptions. Additionally, it is predicted that classroom engagement in the form of coteaching enhances these positive effects. Two natural field experiments, one involving two semesters of professional sales students (n = 90), the other involving four semesters of professional sales students (n = 174), are conducted to test the conceptual model. Results confirm the study’s predictions that sponsoring firms are perceived more favorably by students, and classroom engagement enhances these positive perceptions. Finally, results suggest that firms with lower initial familiarity among students have the most to gain in terms of enhancing student perceptions through coteaching.

Students’ Mathematical Creative Thinking Ability with Posing-Exploring-Doing-Evaluating (PEDE) Productive Failure Model in New Normal

Students’ creative thinking ability is essential to be developed in Mathematics because it can help students solve everyday life problems. This study aimed to determine the impact of the Posing-Exposing-Doing-Evaluating (PEDE) Productive Failure model on developing students’ creative thinking ability in mathematics in the new normal. The study was conducted at Diplahan National High School of the Division of Zamboanga Sibugay to Grade-11 students enrolled for the school year 2020-2021. The study employed a quasi-experimental pretest-posttest control group design. The experimental group was exposed to PEDE Productive Failure Model and the control group was exposed to the Conventional Method. Multiple solution tasks were used to measure students’ level of creative thinking ability. A teacher-made test composed of 4-item open-ended questions with a rubric scale that measures mathematical creative thinking ability was the main instrument used in the study. The mean, standard deviation, and the analysis of covariance (ANCOVA) were used to analyze the data collected. The analysis revealed that students exposed to PEDE Productive Failure Model performed significantly better in terms of creative thinking ability posttest score. Researchers recommend that Mathematics teachers may use PEDE Productive Failure as a modular learning approach in the new normal to develop creative thinking ability in Mathematics. Teachers might also incorporate activities into their Mathematics modules that demand students to present various clearly defined solutions to foster students' creative potential.
Acetaminophen use during pregnancy and offspring attention deficit hyperactivity disorder – a longitudinal sibling control study

Abstract Background Maternal acetaminophen use during pregnancy is associated with increased risk of ADHD in the child. This could reflect causal influence of acetaminophen on fetal neurodevelopment or could be due to confounding factors. The aim of the current study was to examine unmeasured familial confounding factors of this association. Methods We used data from 26,613 children from 12,902 families participating in the prospective Norwegian Mother, Father, and Child Cohort Study (MoBa). The MoBa was linked to the Norwegian Medical Birth Register and the Norwegian Patient Registry. Siblings discordant for prenatal acetaminophen exposure were compared regarding risk of having an ADHD diagnosis. Results Children exposed to acetaminophen up to 28 days during pregnancy did not have increased risk of receiving an ADHD diagnosis compared to unexposed children. The adjusted Hazard ratio (aHR) was 0.87 (95% C.I. = 0.70‐1.08) for exposure 1 to 7 days, and 1.13 (95% C.I. = 0.82–1.49) for 8–28 days. Long‐term exposure (29 days or more) was associated with a two‐fold increase in risk of ADHD diagnosis (aHR = 2.02, 95% C.I = 1.17–3.25). In the sibling control model, the association between long‐term acetaminophen use and ADHD in the child was aHR = 2.77 (95% C.I. = 1.48–5.05) at the between‐family level, and aHR = 1.06 (95% C.I. = 0.51–2.05) at the within‐family level. Conclusions Both the exposed and the unexposed children of mothers with long‐term use of acetaminophen in one of the pregnancies had increased risk of receiving an ADHD diagnosis. This indicates that the observed association between long‐term acetaminophen use during pregnancy and ADHD in the child may at least partly be confounded by unobserved family factors.
Facebook: Social Uses and Anxiety - A Replication Attempt

The relationship between social media use and mental health remains under scrutiny by researchers, policy makers, and the general public. Recently, researchers have addressed whether Facebook use is beneficial to people with high social anxiety. The findings from such studies are mixed, partly due to differences in how variables are operationalised. A well-cited study by McCord et al (McCord, B., Rodebaugh, T. L., & Levinson, C. A., 2014. Facebook: Social uses and anxiety. Computers in Human Behavior, 34, 23-27) suggested that the inclusion of a new variable, Facebook-centric social anxiety, helps explain the complex relationship between general social anxiety and frequency of usage of socially-interactive Facebook features. We undertook two studies (N=202 and N=542; majority British and non-student participants) with the aim of replicating McCord et al (2014), using the original measures (general social anxiety, Facebook-centric social anxiety, and frequency of usage of socially-interactive Facebook features). Replicating the original study, we found a significant positive association between general social anxiety and Facebook-centric social anxiety. However, unlike the original study, we did not find evidence that general social anxiety and Facebook-centric social anxiety interacted to predict frequency of usage of socially-interactive Facebook features. We discuss the implications for future research on social Facebook use.
Supply chain mapping: a proposed construct

During COVID-19, supply chain (SC) mapping has appeared as one of the critical supply chain capabilities that could make a striking difference in organisations’ supply chain performance. Despite its crucial role in responding to SC disruptions, there is a void in the literature on this topic. In this context, the prime objective of the current study is to introduce a comprehensive measure of SC mapping accounting for its various dimensions. A review of the literature is conducted to identify the relevant dimensions and sub-dimensions of SC mapping. Next, two rounds of focused group discussions are conducted in order to refine the identified dimensions and to add any relevant dimensions of SC mapping. Third, we employ exploratory factor analysis to develop the construct of SC mapping. The findings reveal that SC mapping has three major dimensions, namely upstream mapping, downstream mapping, and midstream mapping, with a total 25 items. The developed construct can be used to operationalise the SC mapping and to examine its antecedents and precedents.
Intelligence and radicalization in French prisons: Sociological analysis bottom-up

In the context of the fight against Islamist radicalization in France, prison intelligence rapidly developed from 2015 through the gradual creation of a dedicated service and a specific corps of professionals. This professionalization of prison intelligence work has deeply transformed the prison administration. This article aims to describe and analyse these transformations on the basis of an ethnographic study conducted in radicalization assessment units, which are specific units set up to assess prisoners who have committed or are suspected of committing crimes linked to radical Islam. We shall describe how the guards, probation officers, psychologists and educators participating in assessing the prisoners adapt to the new, encroaching presence of the intelligence mission. We shall analyse the forms of collaboration and competition between this staff and the prison intelligence officers. Lastly, we will examine criticism of the intelligence activity in the radicalization assessment units voiced by various professionals. The interpenetration of the assessment work and the intelligence mission – which are formally distinct missions – produces a specific type of knowledge relating to radicalized prisoners: a reproduction of certain representations or ‘profiles’.
Lateral versus posterior surgical approach for the treatment of supracondylar humeral fractures in children: a systematic review and meta-analysis

Background: Supracondylar humeral fracture (SHF) is the most common type of fracture in children. Moreover, lateral and posterior surgical approaches are the most frequently chosen approaches for open reduction surgery in displaced SHF when C-arm is unavailable. However, previous literature showed mixed findings regarding functional and cosmetic outcomes. Currently, no systematic review and meta-analysis has compared these two procedures. Methods: Our protocol was registered at PROSPERO (registration number CRD42021213763). We conducted a comprehensive electronic database search in MEDLINE, EMBASE, and CENTRAL. Two independent reviewers screened the title and abstract, followed by full-text reading and study selection based on eligibility criteria. The quality of the selected studies was analyzed with the ROBINS-I tool. Meta-analysis was carried out to compare the range of motion (functional outcome) and cosmetic outcome according to Flynn’s criteria. This systematic review was conducted based on PRISMA and Cochrane handbook guidelines. Results: Our initial search yielded 163 studies, from which we included five comparative studies comprising 231 children in the qualitative and quantitative analysis. The lateral approach was more likely to result in excellent (OR 1.69, 95% CI [0.97-2.93]) and good (OR 1.12, 95% CI [0.61-2.04]) functional outcomes and less likely to result in fair (OR 0.84, 95% CI [0.34-2.13]) and poor (OR 0.42, 95% CI [0.1-1.73]) functional outcomes compared to the posterior approach. In terms of cosmetic results, both approaches showed mixed findings. The lateral approach was more likely to result in excellent (OR 1.11, 95% CI [0.61-2.02]) and fair (OR 1.18, 95% CI [0.49-2.80]) but less likely to result in good (OR 0.79, 95% CI [0.40-1.55]) cosmetic outcomes. However, none of these analyses were statistically significant (p> 0.05). Conclusion: Lateral and posterior surgical approaches resulted in satisfactory functional and cosmetic outcomes. The two approaches are comparable for treating SHF in children when evaluated with Flynn’s criteria.
Experimental investigation of dodecylbenzene sulfonic acid and toluene dispersants on asphaltene precipitation of dead and live oil

ABSTRACT Asphaltene is the heaviest fraction of oil, and if the thermodynamic conditions of oil change, it can be separated from oil precipitate. Of common methods for preventing asphaltene precipitation, using predictive methods, biological methods and injection of dispersants can be mentioned. In this study, the effect of two dispersants of toluene and dodecylbenzene sulfonic acid on asphaltene precipitation of a dead and a live oil sample has been investigated. According to the results, these dispersants in dead oil create an optimum point for asphaltene precipitation. In live oil, these dispersants reduce asphaltene precipitation down to 70%. In addition, it was observed that as an effect of injecting these dispersants, the average sizes of asphaltene flocculation have reduced.
Market Reaction to Political Risk: Evidence From the 2018 Brazilian Presidential Election

Abstract The 2018 Brazilian presidential elections coupled unprecedented political instability with a close race between two candidates with antagonistic economic agendas. Using this unparalleled scenario, this paper analyzes the role of political events in shaping the returns on financial assets. The regressions using the Propensity Score Matching technique suggest that companies linked to the government had positive cumulative abnormal returns around relevant events compared with otherwise identical firms. These results reinforce the role of political risk on financial markets in emerging economies and allow economic agents to outline strategies to predict stock return behavior during periods of political turmoil.
The Perception of Mothers on Malaria, Toxoplasmosis and their Pathological Consequences in the Mother and Baby in Biyem-Assi Yaounde

Malaria is a parasitic disease that causes morbidity and mortality in many areas of the world especially in Sub-Saharan Africa and particularly in Cameroon. It is characterised by febrile manifestation, liver inflammation and anaemia. Toxoplasmosis is another parasitic infection caused by an obligate intracellular parasite (Toxoplasma gondii) and is found in many countries of the world. It causes spontaneous abortion in pregnant women and hydrocephally in new- born babies. Malaria and Toxoplasmosis co-infections can cause serious pathological consequences on both mother and fœtus. The aim of this study was to determine the prevalence of malaria, toxoplasmosis, and malaria and toxoplasmosis coinfection in pregnant women during ante natal consultations at Biyem - Assi hospital and to assess their knowledge of the pathological consequences of malaria, toxoplasmosis, and coinfection on the mother and baby. It was a cross-sectional study. Blood samples were collected by finger-prinking and structured questionnaires were administered to 226 pregnant women. The results showed that 39.38 %, 23 % and 8.4 % of women tested positive for malaria, toxoplasmosis and coinfection respectively. The most commonly cited consequence of theses infections was spontaneous abortion. The results obtained showed a significant association between the level of education and the level of knowledge of women about toxoplasmosis and coinfection of toxoplasmosis and malaria (p < 0.05). The level of knowledge of the pregnant woman is not satisfactory as regards toxoplasmosis and co-infection but quite good as regards malaria. The studies have revealed the need for continouos education on toxoplasmosis for pregnant women and girls of childbearing age, and more comprehensive preventive measures. The implementation of public health and education policies that take into account economic, social, environmental and cultural differences are of prime importance.
Effect of Otago Exercise versus Dual Task Net Step Exercise on Balance and Functional Mobility in Community Dwelling Elderly Person with Knee Osteoarthritis - A Randomised Control Trial

Background: Osteoarthritis (OA) is a chronic disease that can change the lifestyle of the affected person by producing pain and decreasing function; OA can result in loss of mobility, pain, disability, and dependence. Impaired balance and increased postural sway (oscillating movements of the body over feet during relaxed standing) both occur with advancing age. Diminished strength is well documented in the elderly. Objective: The purpose of this study was to evaluate the effectiveness of Otago exercise versus dual task net step exercise on balance and functional mobility in community dwelling elderly person with knee OA. Methods: Subjects with knee OA having balance and functional mobility problems were included in this study. Total of 36 both male and female were selected. Subjects those matching the inclusion criteria with age group 60-70 were included for the study. They were randomly divided into two groups; 18 subjects were present in each group. For 4 weeks and 3 days per week. Visual analogue scale, Berg Balance Scale, Time Up and Go test was used to assess the pre and post effects of exercises. Result: Group A showed significant improvement in the balance and functional mobility as compared to group B . So the p-value=0.000<. 05. Conclusion: The study concludes that Otago exercises are more effective than the Dual Task Net Step Exercises in improving balance function and functional mobility in community dwelling elderly persons with knee respectively. Key words: Osteoarthritis, Otago Exercise, Dual Task Net Step Exercise, Berg Balance Scale, Time Up and Go test.
