Abstract This study on the leguminous plant Sesbania tchadica has made it possible to highlight its description, specification and identification in N'Djamena region S. tchadica (Sesbania Sesban Merr. (L)) is an annual tree that measures more than 4 meters in height. This species is abundant especially in Ndjamena. In most of the district of Ndjamena, S. tchadica was the most common type. S. tchadica shows a rapid early growth and grows well in various soils especially sandy siltstone and silty shale. The local inhabitants use the species in many ways: as a medicine, a livestock feed, for improving soil fertility, for fuelwood and to repel desert encroachment. In this study, various academic publishing websites like Science Direct, Springer Nature, some online international plant databases, and other national data herbaria from the republic of Chad were used to identify, describe and summarize the research literature on Sesbania Sesban. This paper also describes the morphological characteristics observed in Sesbania Sesban from the republic of Chad and its taxonomy to assist in future program evaluations.

While some attention has been paid to “what works” to reduce crime, little is known about the effectiveness of programs designed to reduce victimization. This study systematically reviews 83 program evaluations to identify what works to (a) reduce victimization, (b) enhance beliefs/attitudes about victims, and (c) improve knowledge/awareness of victimization issues. Evidence-based findings are organized around 4 major forms of victimization, including bullying, intimate partner violence, sexual abuse, and other general forms of victimization. Determining whether certain types of programs can reduce the risk of victimization has important implications for improving people’s quality of life. Based on our findings, we offer several promising directions for the next generation of research on evaluating victimization programs. The goal of this study is to improve the strength of future program evaluations, replications, and other systematic reviews as researchers and practitioners continue to learn what works to reduce victimization.

Within the Active Living and Well-Being Project (RRP3), funded by the Republic of Slovenia and the European Regional Development Fund Investing in Your Future program, we aim to develop different approaches and prototype solutions to provide ICT solutions for the family in order to connect its members; communicate; promote quality family time, active life, a health-friendly lifestyle and well-being; and integrate various sensor and user-based data sources into a smart city ecosystem platform. A mixed methodology, combined qualitative and quantitative approaches, was selected to conduct the study. An online survey with a structured questionnaire as well as semi-structured interviews were performed. Through the analysis of the results, we tried to establish a family-centered design approach that would be inclusive as much as possible, creating benefits for all generations in order to develop an interactive prototype solution that would allow us to further test and verify different use-case scenarios.

Collections of Gymnopus sect. Impudicae from the Republic of Korea are evaluated. Three recorded species (G. densilamellatus, G. similis, and G. variicolor) are described as new for the science: Gymnopus densilamellatus is macroscopically characterized as having a brown to reddish brown, sometimes pale ochraceous and later whitish pileus and crowded lamellae. Gymnopus similis has an ochraceous-grey, brownish orange or brownish red pileus, and moderately distant, whitish, later dirty yellowish, greyish, or brownish orange or light brown lamellae. Gymnopus variicolor is characterized by a reddish brown, brownish red or violet brown pileus drying-up to light brown or brown, greyish brown or greyish red, later pale brownish orange lamellae, and greyish brown or greyish red pileus, grey-brown, light to reddish brown in upper part. Gymnopus dysodes is recorded for the first time in Korea. The morphological characteristics of the species are provided with a key for their identification. The taxonomic positions of all taxa are confirmed by the DNA sequences of the internal transcribed spacer region and the large subunit of ribosomal rRNA gene.

Apple fruits with anthracnose symptoms were collected from commercial apple orchards in different regions of the Republic of Korea, and isolations were made on potato dextrose agar to isolate the causal agents. The fungal isolates were identified based on their morphological characteristics, growth rates, and multigene sequences. Nine isolates were identified via phylogenetic analysis: three Colletotrichum fructicola, two C. fioriniae, one C. gloeosporioides sensu stricto (s.s.), two C. nymphaeae, and one C. siamense isolates. The pathogenicity of the Colletotrichum isolates was tested using detached apple fruits under laboratory conditions. This study also reidentified six Colletotrichum isolates responsible for apple anthracnose, which were deposited in the Korean Agricultural Culture Collection. Among the six isolates, three were identified as C. siamense (deposited as C. gloeosporioides s.s.), and three were C. nymphaeae (deposited as C. acutatum s.s.). All the Colletotrichum species identified in this study were highly sensitive to tebuconazole in terms of inhibition of mycelial growth (EC50 value of 0.12 to 2.1 μg/ml).

We examine the evidence available on the efficacy of demand-side programs intended to stimulate broadband adoption. We review studies that attempt to measure results. Our suggestions for future program evaluations are to include cost-benefit analysis as a standard part of program review and to make clear that the purpose of evaluation is to assess progress made toward the ultimate policy goals rather than the program’s proximate implementation goals. Appropriate data must be collected to draw conclusions, and appropriate statistical methods must be used to determine the causal impacts of a program. This has rarely been done to date.

Debates on whether or not depleted uranium (DU) causes cancer and other diseases is a hot topic in the public discourse and quite controversial in the scholarly research literature. The issue has grown in importance in the Republic of Serbia after increased rates of morbidity and mortality from malignancies since the 1999 NATO aggression and its use of DU ammunition. At the same time, the fact that the peacekeeping contingents of foreign military personnel involved in clearing the contaminated areas subsequently developed malignant diseases led to what has become known as the Balkan Syndrome. Beside health implications, the social and economic burden of cancer is significant in all countries, especially in transitioning economies, because of health care spending as well as lost productivity due to morbidity and premature death. Therefore, the main aims of this article are to summarize and discuss the current state of knowledge about the negative impact of DU on human health and social impact of cancer, specifically in Serbia, and to encourage rigorous and objective examination of health impacts of DU ammunition and, ultimately, to spotlight the inextricable connection between public health and security, and the indispensable consideration of health from the perspective of national security.

“Open access” has become a central theme of journal reform in academic publishing. In this article, I examine the relationship between open access publishing and an important infrastructural element of a modern research enterprise, scientific literature text mining, or the use of data analytic techniques to conduct meta-analyses and investigations into the scientific corpus. I give a brief history of the open access movement, discuss novel journalistic practices, and an overview of data-driven investigation of the scientific corpus. I argue that particularly in an era where the veracity of many research studies has been called into question, scientific literature text mining should be one of the key motivations for open access publishing, not only in the basic sciences, but in the engineering and applied sciences as well. The enormous benefits of unrestricted access to the research literature should prompt scholars from all disciplines to lend their vocal support to enabling legal, wholesale access to the scientific literature as part of a data science pipeline.
