Intimate relationships and Suicidal Behaviour of Men in Bangladesh

ABSTRACT Suicidal behaviour (e.g., suicide and suicide attempt) is a multifaceted phenomenon which often draws on several social and psychological contexts. This research examines how men’s suicides and attempted suicides are embedded in the contextual praxis of intimate relationships in Bangladesh. Qualitative semi-structured interviews were undertaken with family members, close relatives, and friends of 37 men who died by suicide or attempted suicide. This research’s findings identify five key risk factors associated with men’s suicide and attempted suicide, namely: troubles over the designated family provider’s responsibilities; troubles emanating from second marriage; betrayal of loyalties; complications in non-marital relationships; and feelings of no control over wife. Each theme suggests that men who died by suicide or who attempted suicide found it challenging to balance their culturally expected (hegemonic) masculine image with their intimate relationships. Suicide and attempted suicide surfaced as a consequence of such challenges in their life. Efforts are suggested to lessen the burden on men’s masculine expectations and promote an egalitarian social space in order to reduce suicide risk in men.
Analysis of the Stabilizing Interactions and Thermodynamic Studies in Aluminum-Transition Metal Alloys (Ti, Sc, Mn, Fe) Using Solid-State Electron Density

The solid-state structures of Aluminum-Transition Metal (Al3TM) Alloys (TM = Ti, Sc, Mn, Fe), have been explored in detail using computational electron density methods. Topological analysis of the electron density in Al3Ti alloys revealed two interesting types of interactions between the atoms in the layered Al3Ti alloy structure lattice; viz. Al-Al and Al-Ti interactions. Two types of both Al-Al interactions and Al-Ti interactions were observed between the atoms in the same plane (2.725 A apart), and those on adjacent planes or layers (2.884 A apart). All interactions in the same plane of the Al3Ti alloy are stronger than those on adjacent planes, owing to the high values of the electron density and the bond distances between the interacting atoms (Table 1). The Laplacian of the electron density in a plane of the alloy indicates that Ti atoms are polarized towards the Al-atoms thereby transferring most of their valence electron density to Al (Figure 2b). Similar interactions were observed in Al3Sc alloy but these interactions were weaker than those in Al3Ti alloy. This signifies that Ti and Al atoms in the alloy are interchangeable or completely miscible, and indicates an increased stability of the alloy compared to Al3Sc alloy. In addition, analysis of Al3Mn and Al3Fe alloys indicate that these alloys were more stable compared to Al3Ti and Al3Sc alloys. Furthermore, the thermodynamic studies of Al3TM alloys (TM = Ti, Sc, Mn, Fe) were investigated. The results confirm the conclusion that Al3Ti and other Al-based transition metal alloys play little or no active role in the reversible re/dehydrogenation of Ti-doped NaAlH4. These alloys are thermodynamically stable.
Isolation and Characterization of Two Virulent Phages to Combat Staphylococcus aureus and Enterococcus faecalis causing Dental Caries

This study aimed to isolate and characterize bacteriophages, as a biocontrol agent, against certain antibiotic-resistant bacteria causing dental caries. Here, two dental caries-causing bacteria S. aureus and E. faecalis were isolated and characterized biochemically using the automated VITEK® 2 system. Antibiotic sensitivity pattern of the isolated dental caries bacteria was assessed against selection of antibiotics. The two isolates showed resistance against most of the tested antibiotics. To overcome this problem, two lytic phages vB_SauM-EG-AE3 and vB_EfaP-EF01 were isolated, identified, and applied to control the growth of S. aureus and E. faecalis, respectively. Phages were identified morphologically using TEM and showed that vB_SauM-EG-AE3 phage is related to Myoviridae and vB_EfaP-EF01 phage belongs to Podoviridae. The two phages exhibited high lytic activity, high stability, and a narrow host range. The one-step growth curve of phages showed burst sizes of 78.87 and 113.55 PFU/cell with latent periods of 25 and 30 minutes for S. aureus phage and E. faecalis phage respectively. In addition, the two phages showed different structural protein profiles and exhibited different patterns using different restriction enzymes. The genome sizes were estimated to be 13.30 Kb and 15.60 Kb for phages vB_SauM-EGAE3, vB_EfaP-EGAE1, respectively. Complete inhibition of bacterial growth was achieved using phages with MOIs of 103, 102 and 10 after 1, 3, 5, and 24 h of incubation at 37°C. Hence, this study indicates that the isolated bacteriophages are promising biocontrol agents that could challenge antibiotic-resistant dental caries bacteria to announce new successful alternatives to antibiotics.
A Novel Adaptive Super-Twisting Sliding Mode Control Scheme with Time-Delay Estimation for a Single Ducted-Fan Unmanned Aerial Vehicle

This article proposes a novel adaptive super-twisting sliding mode control scheme with a time-delay estimation technique (ASTSMC-TDE) to control the yaw angle of a single ducted-fan unmanned aerial vehicle system. Such systems are highly nonlinear; hence, the proposed control scheme is a combination of several control schemes; super-twisting sliding mode, TDE technique to estimate the nonlinear factors of the system, and an adaptive sliding mode. The tracking error of the ASTSMC-TDE is guaranteed to be uniformly ultimately bounded using Lyapunov stability theory. Moreover, to enhance the versatility and the practical feasibility of the proposed control scheme, a comparison study between the proposed controller and a proportional-integral-derivative controller (PID) is conducted. The comparison is achieved through two different scenarios: a normal mode and an abnormal mode. Simulation and experimental tests are carried out to provide an in-depth investigation of the performance of the proposed ASTSMC-TDE control system.

Someone Else’s Child: A Co-Constructed, Performance Autoethnography of Adoption from Three Perspectives

Through a framework of reconciling the other, this collaborative autoethnographic performance co-constructs the adoption experience from three perspectives in three different families: a mother struggling with the ethical and emotional implications of the transnational adoption of her daughter; an adult reflecting on her childhood as an adoptee feeling loved, but different; and a woman who met her biological sister at age 28 after her parents revealed a lifelong secret. To develop individual adoption narratives, we applied autoethnographic tools of interactive interviews with family members, reflective writing, and document review (Ellis, 2004) of photos, letters, emails, and calendars. During one school year, we met monthly to discuss relevant literature, share and critique each other’s methods and writing, and identify the common themes in our three, diverse experiences. The result of the iteration of the individual and group processes is a script that weaves together our adoption stories, the discoveries of ourselves, and how, after negotiating feelings and identities, we reconciled the other through positive, loving relationships.
Asymptotic Approximation Ratios for Certain Classes of Online Bin Packing Algorithms

SUMMARY The performance of online algorithms for the bin packing problem is usually measured by the asymptotic approximation ratio. However, even if an online algorithm is explicitly described, it is in general di ﬃ cult to obtain the exact value of the asymptotic approximation ratio. In this paper we show a theorem that gives the exact value of the asymptotic approximation ratio in a closed form when the item sizes and the online algorithm satisfy some conditions. Moreover, we demonstrate that our theorem serves as a powerful tool for the design of online algorithms combined with mathematical optimization
“I Hate to Read-Or Do I?” Low-Achievers and Their Reading

This study is phase two of the Barnstable Study of a Web-based high school summer reading program that replaced traditional summer reading lists. It focuses on low-achieving students who had a low participation rate in the first two years of the program. The researchers interviewed and surveyed seventy students who formed seven focus groups. This study challenges assumptions about struggling readers. Do struggling readers consider themselves readers outside of school where they have choices that relate to what they like to do? Do they read? What do they read? Do they really hate to read? Gender and grade level emerged as factors in participation rates in the program. Student responses emphasized the importance of relevance of reading materials to their reading preferences. Low achievers had a strong preference for alternative reading materials, which has implications for the way schools structure reading for adolescents who are struggling readers.
Visual-attention GAN for interior sketch colourisation

In the professional ﬁeld of interior designing, sketch colouring is often a time-consuming and vapidity task. The traditional neural network does not handle the semantic relationship of sketch lines well, and the colouring effect is unsatisfactory. This paper proposes visual-attention generative adversarial network (VAGAN), which enhances the processing effect of edge semantics, strengthens the network to line edge recognition ability, as well as reduces colour overﬂow and improved model colouring result. In addition, a two-stage training mode is used to simplify the training of rare samples. The simple line draft input into the trained VAGAN, output natural, realistic colour pictures. The experimental results show that, compared with the existing methods, the proposed method can better deal with the problem of sketch and generate stable and reliable images.
Spread of the non-indigenous ascidian Aplidium accarense (Millar, 1953) in the Eastern Mediterranean Sea: morphological and molecular tools for an accurate identification

The aplousobranch ascidian Aplidium accarense (Millar, 1953) was first described on the western coast of Africa, where it is considered native. Afterwards, this species was introduced along south-American Atlantic coasts, where it affected local shellfish farms through a massive colonization of both natural and artificial substrata. Aplidium accarense has been recently reported along Catalan coasts and in the Tyrrhenian Seas (Western Mediterranean) where it represents a non-indigenous species, only recorded in harbours and aquaculture farms thus far. These Mediterranean records support the hypothesis that A. accarense is currently expanding within the basin, representing a potential invasive species. In this study, several colonies of A. accarense were found for the first time on artificial substrata within the semi-enclosed basin of the Mar Piccolo of Taranto (Italy, Ionian Sea), in the Eastern Mediterranean. Here we provide an updated description of A. accarense combining both morphological and molecular approaches, in order to allow an accurate and reliable identification of this expanding species. Comparing the morphology of the specimens collected from Taranto with the previous descriptions, a slight intra-specific variability has been noticed. Therefore, we provide detailed comparisons of the specimens found in Taranto with all the other A. accarense sampled in other areas of the world, in order to highlight the intra-species variability. The correct identification of a potentially-dangerous species such as A. accarense, represents a needed step for environmental monitoring purposes and for implementing management strategies to mitigate the effects of non-indigenous species on natural ecosystems and human activities.
A Critique of Online Learning in Higher Education during the Coronavirus Lockdown Level 5 in South Africa

Despite adapting to the lockdown necessitated by the Coronavirus pandemic, Higher Education Institutions in South Africa have acknowledged that continued lockdown further jeopardizes the 2020 academic calendar. This paper looks at what the Higher Education response has been to continue with academic activity at the onset of Lockdown Level 5. The use of electronic tuition through various media channels has been highlighted since the announcement of lockdown, at all levels of education. While this approach may constitute work-in-progress, it also poses many challenges, chief of which is the high cost of Internet access and data. In this paper, an analytical literature review was conducted using communication media analysis through desktop research. Two conceptual structures, the Technology Acceptance Model (TAM) and Two-way Communication Model (TCM), underpin the study. The paper found that the Coronavirus pandemic and lockdown have forced HEIs to rethink their teaching and learning strategy on the run; that online learning has begun but with varying degrees of success and that implementation presents challenges. Further monitoring post lockdown, to establish the effectiveness of the HEI response, is vital.
Ontogenetic Structure and Temporal Patterns of Summer Ichthyoplankton in Upper Course of the Xijiang River, SW China

The summer ichthyoplankton characteristics in the Laibin section of the Xijiang River were analyzed based on a survey during summer 2017. The ontogenetic structure and temporal patterns of ichthyoplankton and the correlation between environmental parameters and the temporal patterns were investigated. A total of 10,665 eggs and 447 larval belonging to four orders, ten families, and 28 species were collected. According to the flood regime, summer is divided into three periods (pre-flood, flood period, and post-flood). Ichthyoplankton proved to be heterogeneous between periods in summer with differences in the composition and abundance. The assemblages were distinguished by multiple analytical tools, and presented a chronological pattern of marked variability in composition of the species between the periods, and under the strong influence of flood. The assemblages were mainly represented by eggs of S. wui Fang and S. robusta in the pre-flood period, S. argentatus and S. macrops in the flood period, and H. leucisculus and S. curriculus in the post-flood period, while, the larval occurred mainly in the flood period. Understanding these temporal patterns of the upper course of the Xijiang River is useful for the recruitment of fish resources and conservation of fish community diversity.
Effects of Biochar on the Soil Carbon Cycle in Agroecosystems: An Promising Way to Increase the Carbon Pool in Dryland

Dryland agriculture ecosystems occupy an extremely important position in ensuring global food security. However, they have faced problems of low soil organic matter content and poor long-term soil sustainability. Biochar is regarded as a new means of soil remediation and a pathway of carbon sequestration that has improved the soil structure and function of ecosystems due to its complex physical and chemical properties. Since there are few reviews of biochar’s role in the carbon cycle of agricultural ecosystems, this article examines recent research about its influence on plant carbon assimilation, soil organic carbon mineralization and storage. We highlight the direct or potential effects of biochar on the relationships between plant root architecture and carbon storage, the soil priming effect and soil aggregation, to provide new perspectives on the study of its impacts on the carbon cycle and the implications for carbon management in dryland agriculture ecosystems.
Retraction Retraction: Indoor human occupancy detection using Machine Learning classification algorithms & their comparison

-This paper presents a method to determine the occupancy in a room with the help of datasets whose data was collected from different sensors and using different ML algorithms. Features representing the occupancy level and the relative changes are taken from different sensors: Humidity sensors, light sensors,temperature sensors carbon dioxide ( CO2) sensors. Different classification algorithms which are used for detection of occupancy are: Naive Bayes, classification via regression, random forest, simple logistic, multiclass classification, decision table. The result of the classifier can be classified in the class called - binary-class (which refers to the presence or absence of the person).
Generative adversarial networks for data augmentation and transfer in credit card fraud detection

Abstract Augmenting a dataset with synthetic samples is a common processing step in machine learning with imbalanced classes to improve model performance. Another potential benefit of synthetic data is the ability to share information between cooperating parties while maintaining customer privacy. Often overlooked, however, is how the distribution of the data affects the potential gains from synthetic data augmentation. We present a case study in credit card fraud detection using Generative Adversarial Networks to generate synthetic samples, with explicit consideration given to customer distributions. We investigate two different cooperating party scenarios yielding four distinct customer distributions by credit quality. Our findings indicate that institutions skewed towards higher credit quality customers are more likely to benefit from augmentation with GANs. Relative gains from synthetic data transfer, in the absence of feature set heterogeneity, also appear to asymmetrically favour banks operating on the lower end of the credit spectrum, which we hypothesise is due to differences in spending behaviours.
Protective Factors for Military Veteran Fathers’ Parenting Functioning and Satisfaction

Employing a strengths-based perspective, this study examined protective factors related to fathers’ positive parenting behaviors and parenting satisfaction. The sample included 3,810 active duty veteran fathers who separated from the active component and had at least one child 18 years and younger. Logistic regression analyses indicated that financial status, health functioning, resilience, social support, positive social functioning with community and friends, and positive social functioning with relatives were all associated with parenting functioning. The interaction of the number of deployments and resilience was related to parenting functioning. Furthermore, health functioning, resilience, social support, positive social functioning with community and friends, and positive social functioning with relatives were associated with parenting satisfaction. Among fathers in a romantic relationship, the interaction of the number of deployments and romantic relationship functioning and the interaction of the number of deployments and romantic relationship satisfaction were both related to parenting functioning and parenting satisfaction.
Heavy Metal Pollution Assessment in Stream Sediments from Urban and Different Types of Industrial Areas in South Korea

ABSTRACT Stream sediments from heavily industrialized areas, including urban areas (SS), industrial complexes (US), petrochemical industries (PS), and the Onsan industrial complex (OS) in Korea, were studied to identify 19 heavy metals pollution status and the metal sources. The concentration of heavy metals, except for Li, Be, and Cs in the stream sediments from the Onsan industrial complex near the largest Cu/Zn/Pb smelting facilities, was 3 to 1,302 times higher than that in urban and other industrial areas. Moreover, owing to the smelting activity in the Onsan area, the degree of pollution by major metal products (e.g., Cu, Zn, Pb, Sn, Cd, Sb, Ag) and raw or additive materials (Cr, Ni, Mo, As, Hg) was significantly higher than that in other areas. Heavy metals in stream sediments near smelters greatly exceeded the screening levels (SEL), which could have adverse effects on the health of biota. These values also exceeded the cleanup screening levels of freshwater sediments in the USA. The highest pollution load index value of 47.8 was observed in the vicinity of the smelter (OS) and decreased in the following order: heavy industry (3.6, US) > petrochemical industry (2.4, PS) > urban streams (1.2, SS). Our results suggest that metal pollution in stream sediments might be caused by atmospheric dust generated during the smelting process, as well as sediment particles that accumulate and are washed off from impervious layers such as industrial facilities, raw material storage yards, and road surfaces.
Direct Shoot Organogenesis from Lycium chinense Miller Leaf Explants and Assessment of Genetic Stability Using ISSR Markers

An efficient in vitro direct shoot regeneration system has been described for Lycium chinense Miller using leaf explants. Influence of various parameters such as growth regulator concentration, explant type, effect of basal salt type, Murashige and Skoog (1962) medium (MS), Schenk and Hildebrandt (1972) medium (SH), Gamborg et al. (1968) medium (B5), and carbon sources (sucrose, maltose, and fructose) on the regenerating shoots has been studied. Micromorphological studies and genetic fidelity of regenerated shoots were assessed and compared with those of the donor plants. Among the different concentrations of plant growth regulator (PGRs) tested, MS supplemented with lower concentration of 6-benzylaminopurine (BAP) (0.5 mgL−1) and thidiazuron (TDZ) (0.5 mgL−1) increased the frequency of shoot. Comparatively, indole-3-butyric acid (IBA) was more effective in the regeneration and growth of the root system. A higher number of root formation (6.67 ± 1.25) was observed when the rooting medium comprised half-strength MS salts supplemented with 3% sucrose. The surviving plantlets were gradually transferred to the greenhouse and natural soil. More than 90% of the plantlets survived and matured within 85 days. Similarity in the band patterns produced by inter simple sequence repeat (ISSR) primers confirmed the genetic stability and uniformity between the regenerated and donor plants. The present optimized direct shoot regeneration system may be useful for mass propagation and improving the genetic traits in L. chinense.
