The article presents the classification of samples for comparative research, the study of which will contribute to the correct choice of a tactical method of obtaining them. The material also contains an analysis of the scientific literature related to the classification and systematization of the category in question; alternative grounds for dividing into groups are proposed. Classifying comparative samples, the author focuses on certain problems that practitioners face. Namely: the possibility of obtaining samples for a comparative research before the initiation of a criminal case, the validity of the use of coercion to obtain them, as well as the possibility of using comparative material obtained in the framework of operational search activities for expert studies. In preparing the article, general scientific methods of empirical knowledge (comparison, description), general logical methods of analysis, synthesis, generalization, classification, as well as methods of system-structural analysis were used. The purpose of the study of the problems of obtaining samples is to provide a systematic classification of this category in order to improve the quality of crime investigation. The conclusions made in the article on issues related to obtaining comparative samples at the stage of pre-investigation check and the possibility of using samples obtained during operational search activities are logically presented in the proposed classification.

Abstract. Although the development of research competency is an important goal of higher education in social sciences, instruments to measure this outcome often depend on the students’ self-ratings. To provide empirical evidence for the utility of a newly developed instrument for the objective measurement of social-scientific research competency, two validation studies across two independent samples were conducted. Study 1 ( n = 675) provided evidence for unidimensionality, expected differences in test scores between differently advanced groups of students as well as incremental validities over and above self-perceived research self-efficacy. In Study 2 ( n = 82) it was demonstrated that the competency measured indeed is social-scientific and relations to facets of fluid and crystallized intelligence were analyzed. Overall, the results indicate that the test scores reflected a trainable, social-scientific, knowledge-related construct relevant to research performance. These are promising results for the application of the instrument in the evaluation of research education courses in higher education.

Full textAbstract:
The development of biomedical science requires the creation of biological material collections that allow for the search and discovery of biomarkers for pathological conditions, the identification of new therapeutic targets, and the validation of these findings in samples from patients and healthy people. Over the past decades, the importance and need for biobanks have increased considerably. Large national and international biorepositories have replaced small collections of biological samples. The aim of this work is to provide a basic understanding of biobanks and an overview of how biobanks have become essential structures in modern biomedical research.

Purpose of the study. Is to describe the experience of creating a collection of biological images of tumor tissues and biomaterials, which are control samples, for scientific research in morphology and molecular oncology.Materials and methods. We studied the molecular markers of cell cycle regulation, apoptosis, oncogenesis and angiogenesis, the expression of proteins that regulate inflammation and tumor infiltrate cells in biocollections of verified tumors of common localizations: e. g. thyroid cancer, colorectal cancer, breast cancer, prostate adenocarcinoma, endometrioid adenocarcinoma. Also, tissue fragments with normal structure or non-tumor pathology (autoimmune thyroiditis, adenomatous and thyrotoxic goiter, benign formations of the colon, fibrocystic disease of the mammary glands, benign prostatic hyperplasia, endometrial hyperplasia) were used as control samples or comparison groups. The total number of tissue samples is n = 7000.Results. It is reasonable to gather the collection in a pathomorphological laboratory according to the profile of the medical institutions, which has a sufficient volume of incoming target material and specialized morphologists to verify tumors of a given localization. It is necessary to consider the regional and ethnic specifics of the population, which determines the sampling and mutational load. The laboratory must initiate an addition to the informed consent of patients about the possibility of conducting morphological and molecular genetic studies for scientific purposes and publishing their results in a depersonalized form for the development of new elaborations, when signing the contracts with legal entities and individuals and when serving patients within an institution. When working with biocollections, it has to consider having registers of tissue biomaterials of target disorder groups of main localizations with downloading by year from an accessible information system, consider external factors affecting the database (changes in clinical recommendations and classifications, the population of patients served, pandemics and other significant events). The standard of the preanalytical stage, data collection, development of protocols for analytical molecular genetic studies and their evaluation, the utilization of the capabilities of working with reagents for scientific tasks and modeling experiments on laboratory animals are crucial.Conclusion. The formed biocollection made it possible to carry out a number of initiative and funded domestic and international scientific projects at the request of clinicians and fundamental researchers, as well as to improve the quality standards of morphological and molecular genetic oncology diagnostics. Biobanking makes the pathological archive more accessible for review and use, significantly expanding its scientific and practical potential. Scientific and medical research do not conflict and can be used within the same laboratory.

Being a scientist, especially a clinical research one, is a noble but tough job. Scientific job is different from other jobs in terms of working hour and pressure; they need more freedom in their job & research that also put lots of responsibility on them. Research is funded by public money and it is the responsibility of scientists to gain maximum output from it. Clinical research is very complex and involves the use of animal, microbial as well as human samples and volunteers which make it more prone to ethical scrutiny. Minority of researchers who commit fraudulent use of public money & unethical clinical practice threaten public support for science. Now a day, there is growing concern of public and politicians on the freedom of scientists and unethical scientific practice in clinical trials. The most efficient measures to prevent scientific misconduct are awarenessnotably, self-awareness education and transparency. Most of the developed countries have formulated their own guidelines to ensure proper utilization and ethical clinical research and trials. Bangladesh is still lagging behind in terms of regulation and monitoring of clinical research and trials. This review aims to make related peoples to be aware of the necessity of its own guidelines for clinical research and trials.

Full textAbstract:
Aim/Purpose: The purpose of this article is to present clear definitions of the population structures essential to research, to provide examples of how these structures are described within research, and to propose a basic structure that novice researchers may use to ensure a clearly and completely defined population of interest and sample from which they will collect data. Background: Novice researchers, especially doctoral students, experience challenges when describing and distinguishing between populations and samples. Clearly defining and describing research structural elements, to include populations and the sample, provides needed scaffolding to doctoral students. Methodology: The systematic review of 65 empirical research articles and research texts provided peer-reviewed support for presenting consistent population- and sample-related definitions and exemplars. Contribution: This article provides clear definitions of the population structures essential to research, with examples of how these structures, beginning with the unit of analysis, are described within research. With this defined, we examine the population subsets and what characterizes them. The proposed writing structure provides doctoral students a model for developing the relevant population and sample descriptions in their dissertations and other research. Findings: The article describes that although many definitions and uses are relatively consistent within the literature, there are epistemological differences between research designs that do not allow for a one-size-fits-all definition for all terms. We provide methods for defining populations and the sample, selecting a sample from the population, and the arguments for and against each of the methods. Recommendations for Practitioners: Social science research faculty seek structured ways in which to present key research elements to doctoral students and to provide a model by which they may write the dissertation. The article offers contemporary examples from the peer-reviewed literature to support these aims. Recommendation for Researchers: Novice researchers may wish to use the recommended framework within this article when developing the relevant section of the dissertation. Doing so provides an itemized checklist of writing descriptions, ensuring a more complete and comprehensive description of the study population and sample. Impact on Society: The scientific method provides a consistent methodological approach to researching and presenting research. By reemphasizing the definitions and applications of populations and samples in research, and by providing a writing structure that doctoral students may model in their own writing, the article supports doctoral students’ growth and development in using the scientific method. Future Research: Future researchers may wish to further advance novice researcher knowledge in developing models to guide dissertation writing. Future studies may focus on other essential areas of research, including studies about recruitment methods and attrition strategies, data collection procedures, and overall research alignment. Additionally, future researchers may wish to consider evaluating doctoral student foundational knowledge about populations and samples as part of the research process.

Sample size calculation is part of the early stages of conducting an epidemiological, clinical or lab study. In preparing a scientific paper, there are ethical and methodological indications for its use. Two investigations conducted with the same methodology and achieving equivalent results, but different only in terms of sample size, may point the researcher in different directions when it comes to making clinical decisions. Therefore, ideally, samples should not be small and, contrary to what one might think, should not be excessive. The aim of this paper is to discuss in clinical language the main implications of the sample size when interpreting a study.

Biotechnology is developing at an ever-increasing pace, and the progressive computerization of health care and research is making it increasingly easy to share data. One of the fastest growing areas is biobanking. However, even with the best equipment and the best trained staff, a biobank will be useless without donors. For this reason, we have decided to gauge Polish citizens’ awareness and attitudes towards biobanking and their willingness to donate biological samples. For this purpose the survey was conducted among a nationwide group of 1052 Poles aged 18 and over where the totals for gender, age and place of residence were selected according to their representation in the total population of adult Poles. The survey was conducted using the Computer Assisted Web Interview (CAWI) technique. Approximately two thirds of respondents N = 701 (66.6%) indicated that they had heard of scientific studies in which samples of biological material such as blood, saliva or urine are collected. More than half of respondents (N = 613, 58.3%) had a positive opinion regarding scientific research in which samples of biological material are taken. Only N = 220 (20.9%) of respondents had previously encountered the term biobanking. More than a half N = 687 (65.3%) of respondents would participate in a scientific study that biobanked biological material and health information. Almost half of the respondents (48.0%) would like specific consent to be used in biobanking. In our study we observed a negligible correlation between socio-demographic factors and a willingness to donate biological material to a biobank. Considering the results presented above, the level of knowledge and awareness of biobanks, and their role in scientific research and the health care system, among Polish citizens is low and requires education and information activities.

Abstract This article weaves together the intricate realms of authorship and scientific capital within the context of the Tumor Bank at Mexico’s National Institute of Cancerology (INCan). As intellectual property paradigms continue to evolve, the notion of authorship emerges as an intriguing avenue for the dissemination of knowledge. This study employs ethnographic methods to investigate the multifaceted conflicts involving the ownership of biological samples, the authorship of research outputs, and scientific capital. In the context of INCan’s research setting, the discrepancies in sample distribution serve as a symbolic reflection of the scientific capital and influence exercised by researchers. In doing so, interviews with INCan researchers illuminate how intricate collegial and personal relationships and alliances are navigated in order to secure coveted samples. Within this intricate interplay, credibility and power dynamics intertwine, crafting a tapestry of considerable complexity shaping the nuanced dynamics of authorship within the academic sphere.

The issue of conducting consumer research based on student samples has been discussed in scientific journals on economics and management since the 1970s. The large scale of experiments and surveys involving students, as well as the relatively common perception this social group as research representatives of other groups (e.g. adults or generation Y), raise methodological doubts. Students are not typical consumers, therefore they should not be the first or the only choice of researchers, as has often been the case. The aim of the paper is to define both the opportunities and limitations connected to using student samples in consumer research, and to show the scale of this phenomenon in studies conducted in Poland. A content analysis (supported by a frequency analysis) of 64 articles from ‘Handel Wewnętrzny’ (‘Internal Trade’) journal from 2009–2018, containing research results in which students were either the only research group or one of two groups, was carried out. The results of the analyses partly confirm the methodological problems signaled in foreign literature. In Poland, there is no overuse of student samples in scientific research. The problem lies rather in the lack of diligence in the description of research methods and the generalization of research results to broadly defined populations (e.g. young consumers).

Full textAbstract:
Using primary data generated from samples of research units within the Gambia public research sector, this two-phased inquiry seeks to identify and explain factors in research governance that influence scientific knowledge production. In contributing to empirical discussions on the impact levels of different governance models and structures to scientific output, which appear limited and mixed in literature, this study suggests, first, that scientific committee structures with significant research steering autonomy could not only directly contribute to scientific output, but also indirectly through moderating effects on research practices. It further argues that autonomous scientific committee structures tend to play a better steering role than a management-centric model and structure of research governance. Second, elaborating and providing a more insightful explanation and perspective on individual research behaviours and outcome of research, the study argues that communication and collaborative networks could improve research practices and behaviours, which is a most important predictor of scientific performance. Third, research related behaviours are multi-dimensional; they include publication behaviour, publication orientation, funding behaviour, decisions about research priorities and agenda, as well as the communication behaviour of the scientist — all of which are critical for scientific knowledge production. Fourth, analysis of results suggests that intrinsically motivated curiosity is crucial in driving creative and innovative research. For this reason, results of analysis showing negative contribution of non-supportive institutional conditions and positive contribution of intrinsic motivation suggest far reaching implications for the competiveness of a country like Gambia, which is still working to build and improve its science and technology base.

The primary goal of this research is to introduce instances of a scientific approach to divine parables on creation SADPC as insights into empirical research, entrepreneurial, and intellectual development. The research also examines the relationship between divine parables’ engagement and cognitive science enhancement for the selected case samples of university students in Uganda and Malaysia. The deductive and descriptive correlational analyses were used. On the one hand, the deductive approach used the selected Qur’anic parables as benchmarks for methods, procedures, analyses, and SADPC generalizations. On another hand, the descriptive correlational methods were used to analyze the perceived relationship between divine parables’ engagement and cognitive science enhancement using the two samples’ statistics in question. The deductive findings demonstrated the novelty, comprehensiveness, and relevance of the divine parables’ insights into human scientific cognition. The correlational analyses yielded the rejection of (H0) and installed a (Ha) that there is a significant relationship between divine parables’ engagement and cognitive science enhancement for the selected samples. This research introduced both the Islamic intellectual development model (IIDM) and the Islamic entrepreneurial planning model (IEPM) using SADPC. The SADPC significantly demonstrated an insight into empirical research, entrepreneurial, and intellectual development outlook for future Islamic science research.

During the development of higher education institutions, the scientific component has become an inseparable part of educational activities, making it crucial to train competent professionals with scientific research skills. Our study presents innovative teaching methods applicable in the «Fundamentals of Scientific Research» course. We incorporated two methods into the educational process: Research-Based Learning (RBL) and the Genre-Based Approach. To implement this concept, we chose the synthesis and analysis of d-metal oxalates (Fe2+, Co2+, Ni2+, Cu2+) as a model. Students individually carried out the entire research process: from processing the scientific literature through planning and executing the synthesis method to X-ray diffraction analysis of the obtained samples, followed by graphical representation of the results and documentation in the form of a scientific publication. The selected compounds were synthesized from aqueous solution using equimolecular metal sulfate and potassium oxalate quantities. X-ray diffraction studies confirmed the success of the synthesis and the phase homogeneity of the obtained samples. The students presented their research results at the X International Young Researchers Scientific-Practical Conference, thus gaining real publication experience.

Material samples form an important portion of the data infrastructure for many disciplines. Here, a material sample is a physical object, representative of some physical thing, on which observations can be made. Material samples may be collected for one project initially, but can also be valuable resources for other studies in other disciplines. Collecting and curating material samples can be a costly process. Integrating institutionally managed sample collections, along with those sitting in individual offices or labs, is necessary to faciliate large-scale evidence-based scientific research. Many have recognized the problems and are working to make data related to material samples FAIR: findable, accessible, interoperable, and reusable. The Internet of Samples (i.e., iSamples) is one of these projects. iSamples was funded by the United States National Science Foundation in 2020 with the following aims:enable previously impossible connections between diverse and disparate sample-based observations;support existing research programs and facilities that collect and manage diverse sample types;facilitate new interdisciplinary collaborations; andprovide an efficient solution for FAIR samples, avoiding duplicate efforts in different domains (Davies et al. 2021) The initial sample collections that will make up the internet of samples include those from the System for Earth Sample Registration (SESAR), Open Context, the Genomic Observatories Meta-Database (GEOME), and Smithsonian Institution Museum of Natural History (NMNH), representing the disciplines of geoscience, archaeology/anthropology, and biology.To achieve these aims, the proposed iSamples infrastructure (Fig. 1) has two key components: iSamples in a Box (iSB) and iSamples Central (iSC). The iSC component will be a permanent Internet service that preserves, indexes, and provides access to sample metadata aggregated from iSBs. It will also ensure that persistent identifiers and sample descriptions assigned and used by individual iSBs are synchronized with the records in iSC and with identifier authorities like International Geo Sample Number (IGSN) or Archival Resource Key (ARK). The iSBs create and maintain identifiers and metadata for their respective collection of samples. While providing access to the samples held locally, an iSB also allows iSC to harvest its metadata records. The metadata modeling strategy adopted by the iSamples project is a metadata profile-based approach, where core metadata fields that are applicable to all samples, form the core metadata schema for iSamples. Each individual participating collectionis free to include additional metadata in their records, which will also be harvested by iSC and are discoverable through the iSC user interface or APIs (Application Programming Interfaces), just like the core. In-depth analysis of metadata profiles used by participating collections, including Darwin Core, has resulted in an iSamples core schema currently being tested and refined through use. See the <u>current version</u> of the iSamples core schema.A number of properties require a controlled vocabulary. Controlled vocabularies used by existing records are kept, while new vocabularies are also being developed to support high-level grouping with consistent semantics across collection types. Examples include vocabularies for Context Category, Material Category, and Specimen Type (Table 1). These vocabularies were also developed in a bottom-up manner, based on the terms used in the existing collections. For each vocabulary, a decision tree graph was created to illustrate relations among the terms, and a card sorting exercise was conducted within the project team to collect feedback. Domain experts are invited to take part in this exercise <u>here</u>, <u>here</u>, and <u>here</u>. These terms will be used as upper-level terms to the existing category terms used in the participating collections and hence create connections among individual participating collections.iSample project members are also active in the TDWG Material Sample Task Group and the global consultation on Digital Extended Specimens. Many members of the iSamples project also lead or participate in a sister research coordination network (RCN), Sampling Nature. The goal of this RCN is to develop and refine metadata standards and controlled vocabularies for the iSamples and other projects focusing on material samples. We cordially invite you to participate in the Sampling Nature RCN and help shape the future standards for material samples. Contact Sarah Ramdeen (sramdeen@ideo.columbia.edu) to engage with the RCN.

Legal issues related to the biobanking of human biological samples are one of the extremely important areas of European law. Biobanks created in Poland as well as the Polish Biobank Network created under the auspices of the Ministry of Science and Higher Education have become a catalyst for the search for solutions and the basis of rights for the functioning of biobanks in Poland as well as the protection of donor rights. Undoubtedly, the lack of legal regulation of biobanks and biomedical research on human biological samples could become a significant problem limiting the development of biobanking and conducting scientific research in Poland. The research attempts to show how representatives of the doctrine of law, bioethics and sociologists have interpreted the principles and standards of biobank operation in Poland from basic human rights, constitutional norms and personal rights.

Full textAbstract:
Control Charts (CC) are the means to “manage the process behaviour” by analysing subsequent samples at regular intervals of time.: good decisions depend on Scientific analysis of data. Often, the data are considered Normally distributed; this is not completely right; data must be analysed according to their distribution: decisions are different with different distributions, because the Control Limits of the CC depend on the distribution. We compare our findings with Shewhart findings; later we extend the ideas to deal with “rare events”, with data not Normally distributed; we compare our results, found by RIT, for various cases in the literature: there is a big difference between the Shewhart CC and the Time Between Events CC; considering that, future decisions of Decision Makers will be both sounder and cheaper, when data are not normally distributed. ARL depends on the data distribution, not only on the “false alarm rate”. The novelty of the paper is due to the Scientific Way of Computing the Control Limits, both for the mean and for the variance.

Full textAbstract:
Introduction. Modern humanities are moving towards compliance with the requirement of evidence and comprehensive validity of their conclusions, the adequacy of the methods used and research strategies to the results obtained. This problem can be briefly summarised as a movement towards argumentative correctness. In the sciences of education, this requirement plays an extremely important role, since it allows one to find tools for the implementation of practical solutions in various segments of education and upbringing. However, the real state of pedagogical textual discourse demonstrates a lot of serious problems. Despite the types and regulations of empirical, theoretical and contextual substantiation long established in classical logic, the authors of scientific pedagogical texts often violate the framework of a meaningful and logically correct discourse. The arguments put forward are often unable to either confirm or refute the conclusions of the authors; sometimes they require serious additions and corrections. This seriously undermines the degree of trust of the reading community (both theorists and practitioners) in the conclusions proposed by the authors, reduces the public authority of pedagogical science and undermines faith in its ability to constructively influence educational practice. Therefore, the need for methodological “intervention” in the argumentative field of scientific pedagogy can be considered quite conditioned. Such a research initiative could be the first step on the trajectory of the return of pedagogy to meet the criterion of methodological correctness. This conclusion is supported by the studies of European philosophers of education, which, together with the authors’ analysis, determines the relevance of the chosen topic of the article.Aim. The present research aims to identify and justify the typology of incorrect arguments in pedagogical texts; and to display the wide spread of incorrect arguments as a field for promising research activities.Results. The results of the study are a typology of incorrect arguments, including: a) arguments that are untenable and inadequate to the defended theses; b) arguments that require serious concretisation and detail; c) structurally complex arguments, which are partially adequate, but, otherwise, they require a radical revision. The typology is added by not being placed on a par with the above three types of arguments, denoted by the cliché “complex argumentation palette”.Methodology and research methods. The research methods were: analysis of the Russian and foreign texts containing incorrect arguments; a selection of sources containing the most widespread argumentation errors; inductive generalisation to construct and substantiate the typology of incorrect arguments in pedagogy; reflection of the result obtained and identification of fragments of the designated topic that are relevant for prospective research.Scientific novelty. The scientific novelty lies in the transfer of the research focus from the traditional designation by pedagogy methodologists of the criteria for the correctness of pedagogical discourse arguments to the identification of a typology of methodologically incorrect arguments, including three adjacent elements, supplemented by an element in which the three above are intertwined in a complex way. The totality of the results obtained can be displayed as a “constructive prohibition” criterion, illustrating to the scientific community ways to justify the results that must be avoided.Practical significance. The practical significance of the results lies in the specific guidelines for incorrect arguments of scientific discourse, which can be metaphorically clichéd as an “example for non-imitation” and, on this basis, increase the degree of adequacy of the arguments to the thesis being defended in one’s own texts.

Full textAbstract:
Medical and population health science researchers frequently make ambiguous statements about whether they believe their study sample or results are representative of some (implicit or explicit) target population. This article provides a comprehensive definition of representativeness, with the goal of capturing the different ways in which a study can be representative of a target population. It is proposed that a study is representative if the estimate obtained in the study sample is generalisable to the target population (owing to representative sampling, estimation of stratum specific effects, or quantitative methods to generalise or transport estimates) or the interpretation of the results is generalisable to the target population (based on fundamental scientific premises and substantive background knowledge). This definition is explored in the context of four covid-19 studies, ranging from laboratory science to descriptive epidemiology. All statements regarding representativeness should make clear the way in which the study results generalise, the target population the results are being generalised to, and the assumptions that must hold for that generalisation to be scientifically or statistically justifiable.

The stability of the standard sample plays a key role in the testing of the smoke detectors. A scientific and effective standard sample selection scheme is proposed in this paper. The repeatability and uniformity of the tested samples are evaluated before and after the environmental acceleration testing, and the most stable standard sample is obtained. At the same time, this paper explores the new application of the standard sample, which can be used in the calibration of the measuring ionization chamber (MIC). This work can greatly reduce the selection time and provide the standard samples for the laboratory of the smoke detectors testing which is scientific and reliable. At the same time, the difficult problem of the calibration of the measuring ionization chamber (MIC) is solved here.

Adequate nutrition is the most important determinant of the human health. Taking into account this factor, development of the technology for special purpose dairy products based on camel milk using probiotic starter cultures that will have the ability to destroy toxic metabolites, produce amino acids, volatile fatty acids and synthesize vitamins is the urgent task. In connection with the objective set, we have developed 4 samples of dairy products based on camel milk, and examined fatty acid composition thereof on the basis of the Scientific Research Institute of Biotechnology FSBEI HE Kemerovo Institute of Food Science and Technology (University). In the scientific article four samples of the product based on milk are considered. The first sample of the fermented Bacterial leaven of thermophilic lactic acid lactococcus, propionic acid and acetic acid bacteria and Bacterial leaven of thermophilic lactic acid sticks АНВ. The second sample was prepared using Bacterial leaven of thermophilic lactic acid sticks АВ and Bacterial leaven of thermophilic lactic acid lactococcus, propionic acid and acetic acid bacteria. The third sample fermented Bacterial leaven of thermophilic lactic acid sticks Бн and Bacterial leaven of thermophilic lactic acid sticks АНВ. The fourth sample prepared with the addition of Bacterial leaven of thermophilic lactic acid sticks АВ and Bacterial leaven of thermophilic lactic acid sticks Бн. Using the method of chemical ionization with positive and negative ions recording on a chromatographic mass-spectrometer, we determined the content of saturated and unsaturated fatty acids in the samples studied. High content of these acids was found in samples № 1 and № 2. In samples 3 and 4, the acid content was low.

Abstract. The proper pre-drilling preparation, on-site acquisition and post-drilling preservation of high-quality subsurface samples are crucial to ensure significant progress in the scientifically and societally important areas of subsurface biosphere and paleoclimate research. Two of the four research themes of IODP and ICDP and one of the four research areas of the Deep Carbon Observatory (DCO) focus on the subsurface biosphere. Increasing understanding of paleoclimate is a central goal of IODP and incorporated within the scope of the IMPRESS program, the successor of the IMAGES program. Therefore, the goal of our IODP–ICDP–DCO–J-DESC–MagellanPlus-sponsored workshop was to help advance deep biosphere and paleoclimate research by identifying needed improvements in scientific drilling planning and available technology, sample collection and initial analysis, and long-term storage of subsurface samples and data. Success in these areas will (a) avoid biological and other contamination during drilling, sampling, storage and shipboard/shore-based experiments; (b) build a repository and database of high-quality subsurface samples for microbiological and paleoclimate research available for the scientific community world-wide over the next decades; and (c) standardize, as much as possible, microbiological and paleoclimate drilling, sampling and storage workflows to allow results and data to be comparable across both space and time. A result of this workshop is the development and suggested implementation of new advanced methods and technologies to collect high-quality samples and data for the deep biosphere and paleoclimate scientific communities to optimize expected substantial progress in these fields. The members of this workshop will enhance communication within the scientific drilling community by crafting a handbook focused on pre-drilling, drilling and post-drilling operations.

<p style="text-align: justify;">School attendance problems are of great research interest, which is reflected in the increase of scientific publications. This increase hinders the adequate follow-up and updating of the scientific community on the subject. The aim of the present bibliometric study lies in the review of the scientific literature published on school attendance problems during 2014-2021. A bibliographic search and analysis of scientific articles was performed, obtaining a definitive sample of 700 documents. Results were extracted and analyzed for the following indicators: temporal productivity, productivity by authors, co-authorship index, productivity by journals, use of topics, research areas addressed and types of samples used. The number of publications indicates a progressive increase of interest on the subject, which has not corresponded to the creation of a specific journal on the subject. There is also evidence of the need for consensus on the topics to be used; the preference for knowing the factors associated with school attendance problems over other areas of research; and the generalized use of community samples as opposed to more specific ones. In conclusion, the characteristics researched on school attendance problems are presented; knowledge that will facilitate the establishment of intervention processes applicable to different contexts and realities.</p>

The National Oceanic and Atmospheric Ad/ministration (NOAA) works to understand ocean and Great Lakes’ environments and their resources, and develop the capability to predict environmental changes. This mission requires a comprehensive oceanographic research program, including the use of undersea technologies. The in situ undersea approach to ocean science allows acquisition of otherwise unobtainable observations, samples, and experimentation. NOAA’s National Undersea Research Program (NURP) places scientists underwater, directly through the use of submersibles, underwater laboratories, and wet diving, or indirectly using remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and ocean observatories. Scientific diving is an integral part of NURP’s research efforts. The program seeks to safely maximize the capabilities of the nation’s scientific diving community through direct assistance from program experts, and development of new and improved technologies. NURP is also the only federal program with the legislative mandate to improve the safety and performance of divers.

Full textAbstract:
Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnaire-based survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7%) and data (85.4%), but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i) the request for applicants to explain what they would like to do with the resources requested; (ii) the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii) the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate.

Full textAbstract:
Newborn screening (NBS) for inborn errors of metabolism and other serious conditions with onset during infancy is a widespread public health initiative. Like other screening programmes, it aims to discover and treat a disease before effects manifest themselves. Recently, there have been two prominent changes in NBS: a substantial increase in the number of conditions screened for and growing attention to secondary use of residual newborn blood spots. Here, we analyse how this latter change has transpired in Norway. In 2018, Norway’s parliament sanctioned the secondary use of NBS samples for epidemiological research unrelated to NBS. This broadened the programme’s scope, co-opting it for research purposes, making samples available for inclusion in Norway’s biobanking strategy. We argue that this transformation is a case of function creep, whereby the function of screening samples is expanded to serve purposes other than helping newborns. The process provided only minimal involvement from ordinary citizens, but it transformed screened infants into potential scientific citizens. Henceforth, all future generations of Norwegians must choose to stay in or opt out of biobank research when they turn sixteen. Additionally, consenting to this research may occasion a second form of function creep, as ‘actionable findings’ are fed back to participants.

The national project for the measurement of radiocarbon includes different scientific partners for the accelerator named ARTEMIS (French acronym for Accélérateur pour la Recherche en sciences de la Terre, Environnement, Muséologie Installé à Saclay), available to the scientific community since 2004 (Cottereau et al. 2007). The French Ministry of Culture uses this accelerator mass spectrometry (AMS) facility at the request of archaeologists or curators of museums or of historical monuments. For the preparation of some samples, a laboratory has been installed at the Centre of Research and Restoration of the Museums of France, located in the Louvre Palace. In this report, the first data carried out on vegetal samples from museum objects or archaeological remains, dates are presented in terms of yr BP (before AD 1950).

Socio scientific issues deals with learning materials related to controversial issues that develop along with the development of scientific and technological advances.This study aims to compare the PjBL learning model with the STEM PjBL learning model based on socio scientific issues in each class in the biology education study program in improving students' scientific literacy. Quantitative research methods are associative and comparative types. This study took research samples from the research population, namely students in the 7th semester of the biology education study program as many as 60 samples. The sampling technique uses simple random sampling. Data collection used a student response questionnaire to the PjBL learning model and a scientific literacy questionnaire. The results of the t test found that there were differences in the responses of regular students A and regular B to the PjBL learning model and the STEM project based learning innovation based on SSI learning model. The results of the correlation test found that there was a significant relationship between the responses of regular B semester 7 biology education students to the PjBL model variables and students' scientific literacy

Full textAbstract:
In the past decade, scientific process skills and scientific attitudes are widely regarded as essential factors influencing students’ achievement and their future career choices. Unfortunately, previous literature found that students’ scientific skills and attitudes tend to be unsatisfactory. Thus, cultivating students’ skills and attitudes is seen as a fundamental goal in science education. This research sought to promote scientific process skills and scientific attitudes of pre-service chemistry teachers using REORCILEA (Research-Oriented Collaborative Inquiry Learning). In this quasi-experimental research, a one-group pretest and posttest design was utilized. A total of 50 pre-service teachers (6 males and 44 females) at a medium-sized public university in Indonesia were recruited for this study. In order to gather data, the Scientific Process Skills Observation Checklist (SPSOC) and the Scientific Attitude Survey (SAS) were administered before and after the intervention. The data obtained in this study were analyzed through a paired-samples t-test and Cohen’s d. The results showed a significant increase from pretest to posttest in scientific process skills and scientific attitude scores during treatment, each with a high effect size. It can be summarized that REORCILEA is effective in fostering scientific skills and positive attitudes of pre-service chemistry teachers to a satisfactory level. It is recommended for educators to apply REORCILEA to other college chemistry courses to improve their performance.

Full textAbstract:
Background: Nursing students do scientific research at the university level not only contributing to the development of the nursing profession but also helping themselves to practice more useful skills for future work. A positive attitude toward scientific research has been shown to motivate students to practice research. Objective: to assess attitudes toward scientific research and explore associated factors of nursing students in Vietnam. Methods: A cross-sectional study design was adopted and conducted on 238 nursing undergraduate students. Study samples were collected from October to November 2021 through a face-to-face meeting with study subjects and an accidental sampling technique. The attitudes Toward Research Scale was used in this study. Results: The study showed that 76.1% of nursing students had a positive attitude toward scientific research. Through simple linear regression analysis, it showed that having been or participating in scientific research projects (p=0.019), scientific research activities (p=0.028); intending to pursue a postgraduate degree (p=0.016); being introduced/invited to participate in scientific research projects (p=0.021) and having contact with people who can guide scientific research (p=0.033) was the factors that affect nursing students' attitudes toward scientific research. Conclusions: Many associated factors influence the attitude toward scientific research of nursing students. Further effective interventions are needed to address this issue
