Opis:
Agile Project Management is a topic that has become popular both in business and academia, since the publication of the Agile Manifesto - a historic landmark in this subject. In the next 20 years, there was a relevant scientific production that must be analyzed to provoke reflection about the knowledge built up in this period. In this sense, this study aims to analyze the relevant scientific literature on Agile Project Management through a systematic review and a bibliometric analysis of articles published in scientific journals with Digital Object Identifier, in English, from the Web of Science and Scopus databases, from 2001 to 2021. The research results enable us to gain insights into the characteristics of this knowledge domain, regarding its volume and evolutionary trend, main contributors (i.e. scientific journals, authors, and their affiliations), main studies, methods used, and its central thematic axes.

Context: In software engineering, snowball sampling has been used as a supplementary and primary search strategy. The current guidelines recommend using Google Scholar (GS) for snowball sampling. However, the use of GS presents several challenges when using it as a source for citations and references. Objective: To compare the effectiveness and usefulness of two leading citation databases (GS and Scopus) for use in snowball sampling search. Method: We relied on a published study that has used snowball sampling as a search strategy and GS as the citation source. We used its primary studies to compute precision and recall for Scopus. Results: In this particular case, Scopus was highly effective with 95% recall and had better precision of 5.1% compared to GS’s 2.8%. Moreover, Scopus found nine additional relevant papers. On average, one would read approximately 15 extra papers in GS than Scopus to identify one additional relevant paper. Furthermore, Scopus supports batch downloading of both citations and papers’ references, has better quality metadata, and does better source filtering. Conclusion: This study suggests that Scopus seems to be more effective and useful for snowball sampling than GS for systematic secondary studies attempting to identify peer-reviewed literature.

Opis:
The anatomy and phylogenetic systematics of a well preserved hadrosauroid dentary collected in the 1990s from uppermost Maastrichtian strata (within chron C29r) of the Figuerola Formation, in the Àger syncline of the southern Pyrenees in northeastern Spain are revised. The specimen represents a new genus and species of basally branching hadrosauroid dinosaur, Fylax thyrakolasus gen. et sp. nov. This taxon is the third hadrosaurid outgroup species erected in Europe so far and the stratigraphically youngest non-hadrosaurid hadrosauroid known to date. It is diagnosed on the basis of a unique combination of characters such as a dorsal region of the coronoid process that is at least as wide anteroposteriorly as 30% of dental battery length, a coronoid process inclined anteriorly less than 80º relative to the alveolar margin of the dentary, steeply inclined and flat occlusal surface of the dental battery, and dentary tooth crowns 2.8–3.3 times taller than wide without marginal denticles and with a pair of major long ridges on the enameled lingual surface. The parsimony analysis confirmed that F. thyrakolasus gen. et sp. nov. is a close outgroup to Hadrosauridae. However, we also found that it is sister to the hadrosauroid Tethyshadros insularis form the late Campanian–early Maastrichtian Adriatic-Dinaric Carbonate Platform (present-day Italy). Maximum likelihood reconstruction of ancestral areas on the time calibrated phylogeny revealed that the ancestry of the Fylax–Tethyshadros clade has Appalachian roots. This study supports an Asian origin for hadrosauroids and subsequent dispersal to Appalachia, where Hadrosauridae likely originated. In this scenario, the Late Cretaceous European Archipelago could have facilitated the dispersal of hadrosaurid outgroups from Asia to Appalachia.

This article gives a methodological overview of three standards against which it is possible to examine the worth of moral theories and to test their true contribution to ethics. These standards or benchmarks are requirements pertaining to metaethics, moral psychology and practical reason. The proposal is that it is only when a theory answers questions raised by these three areas of inquiry together that such a theory can be said to be a substantive theory of morality. While defending the importance of each area I also provide examples on the way to highlight such areas of relevance.

Background: Systematic literature reviews (SLRs) have become a standard practice as part of software engineering (SE) research, although their quality varies. To build on the reviews, both for future research and industry practice, they need to be of high quality. Aim: To assess the quality of SLRs in SE, we put forward an appraisal instrument for SLRs. Method: A well-established appraisal instrument from research in healthcare was used as a starting point to develop the instrument. It is adapted to SE using guidelines, checklists, and experiences from SE. The first version was reviewed by four external experts on SLRs in SE and updated based on their feedback. To demonstrate its use, the updated version was also used by the authors to assess a sample of six selected systematic literature studies. Results: The outcome of the research is an appraisal instrument for quality assessment of SLRs in SE. The instrument includes 15 items with different options to capture the quality. The instrument also supports consolidating the items into groups, which are then used to assess the overall quality of an SLR. Conclusion: The presented instrument may be helpful support for an appraiser in assessing the quality of SLRs in SE.

We have extended Singh (1967) estimator for estimation of population mean in systematic sampling. We have derived the expressions for the bias and mean squared error of the suggested estimator up to the first degree of approximation. We have compared the suggested estimator with existing estimators and obtained the conditions under which the suggested estimator is more efficient. An empirical study has been carried out to demonstrate the performance of the suggested estimator.

Opis:
Material of tesseraspids (Tesseraspidiformes) is reported from the uppermost Severnaya Zemlya Formation (Lochkovian, Lower Devonian) of the Severnaya Zemlya archipelago, in the Russian Arctic, where it is associated with other vertebrate remains, including corvaspids, acanthodians, and large but rare specimens of osteostracans. The tesseraspid material is not abundant, and most often preserved as a “patchwork” of bony platelets (tesserae), except for a few partly articulated specimens. We redescribe the holotype of Tesseraspis mosaica Karatajūtė-Talimaa, 1983, whose head carapace is preserved as a flattened tube of adjacent tesserae. This material is compared to the already published tesseraspid taxa, i.e., T. tessellata Wills, 1935, T. toombsi Tarlo, 1964, T. mutabilis (Brotzen, 1934), T. oervigi Tarlo, 1964 emend. Dineley and Loeffler, 1976, T. denisoni Tarlo, 1964, and T. talimaae Tarlo, 1965. All species are based upon rare and incomplete material, as no head carapaces associated with trunk and tail are known, and so, the intraspecific variability is also unknown. Distinction between “species” is based on the detail of the superficial sculpture of the tesserae of the head carapaces, which is unsatisfactory. It is concluded that only four of the nominal species can be retained. A review of all other known tessellated pteraspidomorphs indicates that our knowledge of tessellated heterostracans is currently insufficient to support a meaningful classification.

Opis:
Celem artykułu jest prezentacja wyników badań naukowych prowadzonych na podstawie analizy danych zastanych dotyczących zjawiska agresji związanej z brakiem poczucia bezpieczeństwa psychicznego wśród uczniów. Analizy prowadzono metodą przeglądu systematycznego raportów badawczych opisujących badania prowadzone w Polsce, których przedmiotem było zjawisko agresji w kontekście poczucia bezpieczeństwa wśród uczniów. Artykuł prezentuje podejście evidence based practise jako podstawę teoretyczną prowadzonych badań i adekwatną do tego podejścia metodę badawczą, jaką jest przegląd systematyczny. Wyniki badań zinterpretowane w syntezie narracyjnej wskazują na zróżnicowaną wartość merytoryczną i metodologiczną 33 analizowanych raportów, których cele badawcze najczęściej koncentrowały się na określeniu skali zjawiska agresji w szkołach i czynnikach  je  warunkujących.  Wnioski  i  rekomendacje  wypływające z przeprowadzonych badań źródeł wtórnych mają znaczenie tak dla teorii interdyscyplinarnych stanowiących podstawy profilaktyki społecznej, jak i dla praktyki profilaktycznej, szczególnie dla pedagogów odpowiedzialnych za realizację programu wychowawczo-profilaktycznego w szkołach i placówkach oświatowych. Strategie profilaktyczne wpisują się w kontinuum ekskluzja – inkluzja, jako że takie właśnie działania mają potencjał zapobiegania pojawianiu się i utrwalaniu zachowań problemowych, które w konsekwencji mogą prowadzić do wykluczenia społecznego.
The aim of the article is to present scientific research based on an analysis of data concerning aggression in terms of pupils feeling inse- cure or vulnerable at school. The analysis was carried out as a systematic review of reports discussing research conducted in Poland. The article presents the evidence-based practice approach as a theo- retical basis for the analysis, and the chosen research method-i.e., systematic review. The results of the research that is interpreted in the narrative synthesis indicate varied substantive and methodological value among the 33 analyzed reports, whose research objectives most often focused on determining the scale of aggression in schools and the factors that determine it. Conclusions and recommendations stemming from the survey of secondary sources are important, both for interdisciplinary theories constituting the basis for social preven- tion and preventative practice, especially for school pedagogues, who are responsible for implementing educational/prophylactic programs in schools and educational institutions. Prophylactic strategies refer directly to the exclusion–inclusion continuum, having the potential to prevent the appearance and perseverance of problematic behavior, which may consequently lead to social exclusion.

Objectives of the research: This study investigates art education as a means of cultivating cultural values and aims to address questions regarding the methodologies employed in previous research on cultural values. The research presented herein constitutes a Systematic Literature Review (SLR) on cultural education, utilizing the PRISM method adopted in 2020. Research methods: This article conducts a Systematic Literature Review (SLR) on cultural education using the PRISM method adopted in 2020. The search was conducted using Perish or Publish (PoP) for Scopus-indexed international journals and the Garuda portal from the Ministry of Education and Culture, focusing on journals indexed in Sinta. Contextual Background: Because the cultural processes continually evolve in response to the forces that influence culture, cultural acculturation serves as a foundation for arts and cultural workers’ efforts to inculcate the values of local wisdom within educational settings. Research findings: Data collection spanned from 2010 to 2022, resulting in the retrieval of 14 international articles and 16 national articles based on their titles and abstracts, totaling 30 articles. These articles originated from various countries, including Belgium, the Czech Republic, Germany, Korea, Poland, Taiwan, China, Istanbul, Slovenia, Turkey, Estonia, and Indonesia. Analysis of the articles revealed that music arts education constituted 27%, arts and culture 33%, local wisdom 14%, dance education 17%, art education 3%, and theatre education 3%. In terms of research methodologies, the study identified action research at 5%, Research and Development at 10%, quantitative research at 10%, qualitative case study research at 7%, literature review at 7%, and qualitative research at 56%. Conclusions and recommendations: Through this SLR, the researcher aims to pave the way for future in-depth research in arts and culture education or for exploring novel approaches.

Context: Software measurement programs are essential to understand, evaluate, improve and predict the software processes, products and resources. However, successful implementation of software measurement programs (MPs) in small and medium enterprises (SMEs) is challenging. Objective: To perform a detailed analysis of studies on MPs for highlighting the existing measurement models, tools, metrics selection methods and challenges for implementing MPs in SMEs. Methods: A Systematic Mapping Study (SMS) is conducted. Results: In total, 35 primary studies are comprehensively analyzed. We identified 29 software measurement models and 4 tools specifically designed for MPs in SMEs. Majority of the measurement models (51%) are built upon software process improvement approaches. With respect to measurement purposes of models, the distribution of MPs was identified as: characterization (63%), evaluation (83%), improvement (93%) and prediction (16%). Majority of primary studies discussed the use of measurement experts and experience (60%) followed by the use of measurement standards (40% and the use of automated tools (22%) for metrics selection in MPs. We found that the SMEs and large organization face different challenges as studies in SMEs report challenges that exist even before the implementation of MPs due to infrastructure and management processes of SMEs. The challenges reported by studies in large organizations are mostly related to the issues discovered while implementing MPs. Conclusion: The analysis of measurement models, tools, metrics selection methods and challenges of implementing MPs should help the SMEs to make a feasibility study before implementing a MP.

Opis:
Purpose: Rectal cancer is one of the most common malignancies of the gastrointestinal tract. The gold standard method is surgical resection. The approach to rectal cancer is still controversial. Nowadays, robotic approach gains popularity in comparison to traditional laparoscopy. However, there is lack of studies assessing rectal resections with primary anastomosis. Methods: We performed a systematic review and meta-analysis according to the PRISMA guidelines. The primary outcomes of interest were morbidity and short-term complications. Results: An initial reference search yielded 1250 articles. Finally, we chose six studies covering 1580 patients that we included in the quantitative analysis. In our study, we demonstrated that laparoscopic and robotic surgery are non-inferior to one another in terms of morbidity (RR=1.1 95% CI: 0.89-1.39), major complication rate (RR=1.01, 95% CI: 0.60-1.69) or in length of hospitalization (MD=0,15 95% CI: -0.60−0.90). The latter has slight advantage in quality of mesorectal excision (RD = -0.19, 95% CI: -0.35 − -0.03. I2=69%) and anastomotic leakage rate (OR=2.25, 95% CI: 1.23-4.09, I2=0%). Conclusion: In certain cases Robotic Surgery provide better quality of resected specimen and lower leakage ratio, nevertheless due to heterogeneity the results are uncertain. There is substantial need for large randomized controlled studies.

Opis:
The issue of stability controlling cutting slopes is particularly important in clay-shale slopes, a typical expanding sedimentary layer with poor engineering geological conditions and mechanical characteristics. Therefore, research on the causes of failure and remedies for clay-shale cutting slopes is required to serve as an overview for handling and preserving clay-shale slopes in identical conditions. However, the trusted information about the need for further related clay shale research and clay shale in slope stability has yet to be specifically presented. This review study summarizes the published research for clay shale beginning in 1980, presents a bibliometric analysis to examine the published research based on year and country, and provides various study trends in cluster diagram using the VOSviewer program. The analysis also summarized some key goals, effective methodology, and significant findings from the most recent studies to extract information from them that would benefit future research. In conclusion, the results show the need for developing research to fill the knowledge gap regarding clay shale, landslide, and clay mineralogy. In addition, the clay shale slope analysis has revealed the need for additional research into dynamic force and its deformation.

Opis:
Background: The use of ensemble techniques have steadily gained popularity in several software quality assurance activities. These aggregated classifiers have proven to be superior than their constituent base models. Though ensemble techniques have been widely used in key areas such as Software Defect Prediction (SDP) and Software Change Prediction (SCP), the current state-of-the-art concerning the use of these techniques needs scrutinization. Aim: The study aims to assess, evaluate and uncover possible research gaps with respect to the use of ensemble techniques in SDP and SCP. Method: This study conducts an extensive literature review of 77 primary studies on the basis of the category, application, rules of formulation, performance, and possible threats of the proposed/utilized ensemble techniques. Results: Ensemble techniques were primarily categorized on the basis of similarity, aggregation, relationship, diversity, and dependency of their base models. They were also found effective in several applications such as their use as a learning algorithm for developing SDP/SCP models and for addressing the class imbalance issue. Conclusion: The results of the review ascertain the need of more studies to propose, assess, validate, and compare various categories of ensemble techniques for diverse applications in SDP/SCP such as transfer learning and online learning.

Opis:
The increasing level of urbanisation and traffic congestion promotes the concept of urban air mobility (UAM), which has become a thriving topic in engineering and neighbouring disciplines. The development of a suitable ground-based infrastructure is necessary to supply these innovative vehicles, which mainly includes networks of take-off and landing sites, facilities for maintenance, energy supply, and navigation and communication capabilities. Further requirements comprise robust business and operating models for emerging service providers and regulatory frameworks, particularly regarding safety, liability and noise emissions. The objective of this study is to provide an overview of the current results and developments in the field of UAM ground-based infrastructure by conducting a systematic literature review (SLR) and to identify the most relevant research gaps in the field. For the systematic literature analysis, our search string contains vertiports and the equivalents, UAM and equivalents, and search phrases for the individual domains. In the final analysis 64 articles were included, finding a strong focus on simulations and vertiport networks, while specific case studies and related aspects like automated MRO and urban planning appear less frequently. Therefore, this article provides insights for a more holistic perspective on challenges and necessities of future UAM.
