They are critical but time-consuming in research and decision making for various disciplines. When conducting a review, a large volume of data is usually generated from relevant studies. Computer-based tools are often used to manage such data and to support the systematic review process. This paper describes a comprehensive analysis to gather the required features of a systematic review tool, in order to support the complete evidence synthesis process. We propose a framework, elaborated by consulting experts in different knowledge areas, to evaluate significant features and thus reinforce existing tool capabilities. The framework will be used to enhance the currently available functionality of CloudSERA, a cloud-based systematic review Citation: Person, T.; Ruiz-Rube, I.; Mota, J.M.; Cobo, M.J.; Tselykh, A.; tool focused on Computer Science, to implement evidence-based systematic review processes in Dodero, J.M. -
Mothers in Science
The aim of this book is to illustrate, graphically, that it is perfectly possible to combine a successful and fulfilling career in research science with motherhood, and that there are no rules about how to do this. On each page you will find a timeline showing on one side, the career path of a research group leader in academic science, and on the other side, important events in her family life. Each contributor has also provided a brief text about their research and about how they have combined their career and family commitments. This project was funded by a Rosalind Franklin Award from the Royal Society 1 Foreword It is well known that women are under-represented in careers in These rules are part of a much wider mythology among scientists of science. In academia, considerable attention has been focused on the both genders at the PhD and post-doctoral stages in their careers. paucity of women at lecturer level, and the even more lamentable The myths bubble up from the combination of two aspects of the state of affairs at more senior levels. The academic career path has academic science environment. First, a quick look at the numbers a long apprenticeship. Typically there is an undergraduate degree, immediately shows that there are far fewer lectureship positions followed by a PhD, then some post-doctoral research contracts and than qualified candidates to fill them. Second, the mentors of early research fellowships, and then finally a more stable lectureship or career researchers are academic scientists who have successfully permanent research leader position, with promotion on up the made the transition to lectureships and beyond. -
The “Doctrine of Discovery” and Terra Nullius: a Catholic Response
1 The “Doctrine of Discovery” and Terra Nullius: A Catholic Response The following text considers and repudiates illegitimate concepts and principles used by Europeans to justify the seizure of land previously held by Indigenous Peoples and often identified by the terms Doctrine of Discovery and terra nullius. An appendix provides an historical overview of the development of these concepts vis-a-vis Catholic teaching and of their repudiation. The presuppositions behind these concepts also undergirded the deeply regrettable policy of the removal of Indigenous children from their families and cultures in order to place them in residential schools. The text includes commitments which are recommended as a better way of walking together with Indigenous Peoples. Preamble The Truth and Reconciliation process of recent years has helped us to recognize anew the historical abuses perpetrated against Indigenous peoples in our land. We have also listened to and been humbled by courageous testimonies detailing abuse, inhuman treatment, and cultural denigration committed through the residential school system. In this brief note, which is an expression of our determination to collaborate with First Nations, Inuit and Métis in moving forward, and also in part a response to the Calls to Action of the Truth and Reconciliation Commission, we would like to reflect in particular on how land was often seized from its Indigenous inhabitants without their consent or any legal justification. The Canadian Conference of Catholic Bishops (CCCB), the Canadian Catholic Aboriginal Council and other Catholic organizations have been reflecting on the concepts of the Doctrine of Discovery and terra nullius for some time (a more detailed historical analysis is included in the attached Appendix). -

How Science Works
PB 1 How science works The Scientific Method is traditionally presented in the first chapter of science text- books as a simple recipe for performing scientific investigations. Though many use- ful points are embodied in this method, it can easily be misinterpreted as linear and “cookbook”: pull a problem off the shelf, throw in an observation, mix in a few ques- tions, sprinkle on a hypothesis, put the whole mixture into a 350° experiment—and voila, 50 minutes later you’ll be pulling a conclusion out of the oven! That might work if science were like Hamburger Helper®, but science is complex and cannot be re- duced to a single, prepackaged recipe. The linear, stepwise representation of the process of science is simplified, but it does get at least one thing right. It captures the core logic of science: testing ideas with evidence. However, this version of the scientific method is so simplified and rigid that it fails to accurately portray how real science works. It more accurately describes how science is summarized after the fact—in textbooks and journal articles—than how sci- ence is actually done. The simplified, linear scientific method implies that scientific studies follow an unvarying, linear recipe. But in reality, in their work, scientists engage in many different activities in many different sequences. Scientific investigations often involve repeating the same steps many times to account for new information and ideas. The simplified, linear scientific method implies that science is done by individual scientists working through these steps in isolation. But in reality, science depends on interactions within the scientific community. -
Using the Scientific Method
Using the Scientific Method 2002 and 2014 GED Content Area: Science Focus: Scientific Method (2002) and Scientific Hypothesis and Investigation(2014) Activity Type: Graphic Organizer and GED Practice Objectives Students will be able to: Appreciate the purpose of the Scientific Method Understand key terms related to the Scientific Method: observation, hypothesis, test, experiment, result, conclusion Relate the Scientific Method to an experiment Answer GED questions based on the Scientific Method Directions 1. Print the handout “Using the Scientific Method” (next page). Pass out the handout to the class. 2. Explain that the scientific method is the way scientists learn about the world around us. This involves several steps, often in the form of experiments. Discuss the 5 steps in the chart on the handout and define the highlighted words. 3. Have a student or students read the first passage out loud. Ask the class to fill in the chart. They can fill in the chart individually or in pairs (discussing these concepts can help students develop their thinking skills). 4. Discuss the students’ answers. Samples: 1. Observation: Where there was Penicillium mold, there were also dead bacteria. 2. Hypothesis: The mold must produce a chemical that kills the bacteria. 3. Test: Grow more of the mold separately and then return it to the bacteria. 4. Result: When the material is returned to the mold, the bacteria died. 5. Conclusion: Penicillium kills bacteria. 5. Have students read the passage at the bottom of the page and answer the GED practice question. Choice (4) is correct because the doctor saw that when the chickens ate whole‐grain rice with thiamine, they did not have the disease. -
Principles of Scientific Inquiry
Chapter 2 PRINCIPLES OF SCIENTIFIC INQUIRY Introduction This chapter provides a summary of the principles of scientific inquiry. The purpose is to explain terminology, and introduce concepts, which are explained more completely in later chapters. Much of the content has been based on explanations and examples given by Wilson (1). The Scientific Method Although most of us have heard, at some time in our careers, that research must be carried out according to “the scientific method”, there is no single, scientific method. The term is usually used to mean a systematic approach to solving a problem in science. Three types of investigation, or method, can be recognized: · The Observational Method · The Experimental (and quasi-experimental) Methods, and · The Survey Method. The observational method is most common in the natural sciences, especially in fields such as biology, geology and environmental science. It involves recording observations according to a plan, which prescribes what information to collect, where it should be sought, and how it should be recorded. In the observational method, the researcher does not control any of the variables. In fact, it is important that the research be carried out in such a manner that the investigations do not change the behaviour of what is being observed. Errors introduced as a result of observing a phenomenon are known as systematic errors because they apply to all observations. Once a valid statistical sample (see Chapter Four) of observations has been recorded, the researcher analyzes and interprets the data, and develops a theory or hypothesis, which explains the observations. The experimental method begins with a hypothesis. -

It achieves this status in physics because it provides unification for contradictory laws of physics, namely quantum mechanics and general relativity. While based on advanced theoretical mathematics, its public discourse is growing in prevalence and its rhetorical power is leading to a scientific revolution, even among the public. -
Hempel and Confirmation Theory
Hempel and Confirmation Theory Jan Sprenger* June 15, 2020 Carl Gustav Hempel (1905–1997) was one of the primary exponents of logical empiricism. As a student and member of the Gesellschaft für em- pirische Philosophie in Berlin, alongside Reichenbach and Grelling, he wit- nessed the emergence of logical empiricism as a philosophical program. From the mid-1930s onwards, his contributions shaped its development, too. Hempel studied primarily in Göttingen and Berlin, but in 1929/30, he also spent a semester in Vienna studying with Carnap and partici- pated in the activities of the Vienna Circle. Both societies joined forces for organizing scientific events, and founded the journal Erkenntnis in 1930, where many seminal papers of logical empiricism were published, with Carnap and Reichenbach as editors. While the work of the Berlin philosophers is congenial to the project of the Vienna Circle, there are important differences, too. Neither Hempel nor his mentor Reichenbach identified “scientific philosophy” with the project of cleansing science of meaningless statements (e.g., Carnap 1930). Rather, Hempel extensively used a method that Carnap would apply in later works on probability and confirmation (Carnap 1950, 1952): expli- cation, that is, the replacement of a vague and imprecise pre-theoretical concept (e.g., “confirmation”) by a fruitful and precise concept (e.g., a formal confirmation criterion). Relying on the method of explication, Hempel developed adequacy conditions on a qualitative concept of con- firmation (Hempel 1943, 1945a,b), a probabilistic measure of degree of *Contact information: Center for Logic, Language and Cognition (LLC), Department of Philosophy and Education Sciences, Università degli Studi di Torino, Via Sant’Ottavio 20, 10124 Torino, Italy. -
This Is Dr. Chumney. the Focus of This Lecture Is Hypothesis Testing –Both What It Is, How Hypothesis Tests Are Used, and How to Conduct Hypothesis Tests
TRANSCRIPT: This is Dr. Chumney. The focus of this lecture is hypothesis testing –both what it is, how hypothesis tests are used, and how to conduct hypothesis tests. 1 TRANSCRIPT: In this lecture, we will talk about both theoretical and applied concepts related to hypothesis testing. 2 TRANSCRIPT: Let’s being the lecture with a summary of the logic process that underlies hypothesis testing. 3 TRANSCRIPT: It is often impossible or otherwise not feasible to collect data on every individual within a population. Therefore, researchers rely on samples to help answer questions about populations. Hypothesis testing is a statistical procedure that allows researchers to use sample data to draw inferences about the population of interest. Hypothesis testing is one of the most commonly used inferential procedures. Hypothesis testing will combine many of the concepts we have already covered, including z‐scores, probability, and the distribution of sample means. To conduct a hypothesis test, we first state a hypothesis about a population, predict the characteristics of a sample of that population (that is, we predict that a sample will be representative of the population), obtain a sample, then collect data from that sample and analyze the data to see if it is consistent with our hypotheses. 4 TRANSCRIPT: The process of hypothesis testing begins by stating a hypothesis about the unknown population. Actually we state two opposing hypotheses. The first hypothesis we state –the most important one –is the null hypothesis. The null hypothesis states that the treatment has no effect. In general the null hypothesis states that there is no change, no difference, no effect, and otherwise no relationship between the independent and dependent variables.
