Abstract:

The National Science Foundation Young Scholar Program “The Excitement of Meteorology!” successfully brought the atmospheric and related sciences to high school students in Mississippi. The four-week summer program was administered through the Jackson State University Meteorology Program in the Department of Physics, Atmospheric Sciences, and General Science and was supported by the Mississippi Science Partnership program office. This commuter program provided an opportunity to learn, study, and research the field of meteorology. Through instructional sessions, laboratories, field trips, and peer contact participants were exposed to the concepts of atmospheric motion, the development of storms, and the practical application of meteorology during a one-month period. The program was intended to help students make their own career decisions and to foster their interest in the sciences and meteorology. The goals and objectives of the program were to develop basic science skills; make participants aware of the interdisciplinary nature of meteorology; provide participants with the opportunity to see and hear the meteorologist as a researcher, teacher, and communicator; provide the information and incentive necessary for participants to choose a career in meteorology or the sciences; make participants aware of the various employment opportunities in the field; and show the moral and ethical responsibilities and importance of atmospheric science to society. Thirty sophomore and junior high school student participants (22 females and 8 males, nearly all of whom were African–American) completed the program. All were tested on their meteorological knowledge and skills gained during the program and questioned about their field and lecture experiences. They also “graded” the effectiveness of all speakers, presentations, videotapes, and laboratory sessions. Through surveys it was found that the participants' desire to pursue a science career and to go to college were increased by the program. They also indicated that the program objectives had been met and that the program had met their expectations. They were particularly pleased with the opportunity to work in a college setting and with professional scientists.

Abstract:

VNOS form B is an instrument that has been developed and revised to assess the view of nature of science of preservice science teachers through nature of science aspects.Indeed, students and teachers have to have the view of nature of science to avoid misconceptions of science concepts. Unfortunately, research on the view of Nature of Science is less conducted in Indonesia. This is a qualitative research that was conducted in Borneo University Tarakan. Respondents are preservice biology teachers in the sixth semester. The first step of this research is translating and adapting the VNOS form B into Bahasa Indonesia to make sure that the instrument is culturally fit to Indonesian and the transadapted instrument then given to the respondents. The result shows that the VNOS form B can be applied to assess the view of nature of science of preservice biology teachers. However, the result also shows that most of preservice biology teachers have few understanding on aspects of nature of scince.

Abstract:

We describe the Trump Administration as an “anti-science disaster” and approach study of the phenomenon as other disaster researchers might study the impacts of a drought, hurricane, or wildfire. An important, but rare, element of disaster research is identification of baseline data that allow scientific assessment of changes in social and natural systems. We describe three potential baselines for assessing the nature and impact of Trump’s anti-science rhetoric and (in)action on science, science policy, and politics.

Full text

Abstract:

This thesis contributes to an understanding of the changes in prominence in EU energy policy since the 1990s. It does so by analysing struggles over energy poli-cy developments, as well as focusing on a new way of looking at EU politics, in particular, at the role of the EU Commission in the development of energy policy. Realist and liberal oriented perspectives, and constructivist and discourse ap-proaches, offer competing theoretical frameworks through which to view EU politics, and furnish us with many useful insights. However, they also suffer from some prob-lematic features, such as state-centrism, automatism, determinism, and cultural relativism. Drawing on the neo-Gramscian approach, informed by a historical institution-alist perspective, and certain elements of the post-structuralist account, I provide a more convincing and thorough explanation of several considerable shifts in EU energy policy, beginning with competitiveness in the 1990s, then turning towards energy security as well as climate change in the 2000s, and again competitiveness at the end of the 2000s. In addition, I illuminate the proactive role of the Commission in continuous hegemonic struggles over EU energy policy development. First, using historical institutionalism, I argue that the EU Commission acts as a political entrepreneur, promoting a long-term pro-growth orientation that stems from its organizational DNA, i.e. its historical make-up. Moreover, other state and non-state players often contest the Commission’s forward-looking position. The neo-Gramscian account of hegemony provides a comprehensive and detailed framework that reveals how the Commission, and other players, were actively involved in hegemonic struggles sur-rounding the EU energy policy domain. Furthermore, due to the lack of analytical mechanisms in the neo-Gramscian tradition to explore dynamic struggles and changes at the discursive level, I use the post-structuralist political logics of equivalence and difference, together with various rhetorical instruments that serve as descriptive framing devices.

Full text

Abstract:

Seabird populations are declining worldwide. Two major causes of decline are non-native predators and seabird (indirect or direct) overexploitation; these have been suspected but not assessed in the Caribbean region, including in the southern Grenadine islands. Using cameras, questionnaire surveys, and nest monitoring, I explored the potential of invasive predator presence and seabird harvest in affecting nesting productivity of five species in five uninhabited islands during 2014–2017. Overall, nesting productivity increased (n = 567 nests) despite the confirmed presence of non-native rats. However, my survey of Grenada residents (n = 32 responses) and physical evidence found on the islands (e.g., gun shells) suggest that seabird harvest still occur and may be responsible for previous declines. Additionally, most contributors to harvest did not seem aware of any seabird-protective laws. Therefore, I recommend establishing a community-based monitoring program that educates and empowers residents to prevent seabird harvest and continue nest monitoring.

Abstract:

A number of technical approaches had to be employed within the planner, namely, 1) translating expected reward into a probability of goal satisfaction criterion, 2) monitoring belief states with a Rao-Blackwellized particle, and 3) employing Rao-Blackwellized particles in the McLUG probabilistic conformant planning graph heuristic. POND-Hindsight is an action selection mechanism that evaluates each possible action by generating a number of lookahead samples (up to a xed horizon) that greedily select actions based on their heuristic value and samples the actions' observation; the average goal satisfaction probability of the end horizon belief states is used as the value of each action.

Abstract:

Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students’ understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students’ understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science – High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in Science Olympiad did not translate into informed understandings of NOS. There were implications that labs with a set procedure and given data tables did not contribute to informed NOS understandings, while explicit instruction may have contributed to more informed understandings. Exploring these high achieving, Science Olympiad students’ understandings of NOS was a crucial step to understanding what experiences formed these students’ understandings so that teachers may better their practices and help more students succeed in becoming scientifically literate citizens.

Abstract:

For successful curriculum implementation in the framework of the project “Competency-based Education Curriculum Development and Implementation” funded from the European Social Fund (ESF), it is essential to develop validated and reliable national level tests with an objective to monitor students’ progress. The purpose of the research is to analyse students’ current situation in explaining natural phenomena scientifically in order to give a clear insight into the assessment process of students’ skills. At a first glance, a substantial amount (more than 50 %) of 15-16 years old students are capable of explaining natural phenomena in science, however, detailed analysis reveals two problems: both deep and surface student explanations are scored in the same way in test and item assessing criteria are not allowing teachers to assess student skills at different cognitive levels. Keywords: explaining phenomena scientifically, natural phenomena in science, skill assessment.

Abstract:

Abstract Similarity assessment is a cognitive activity that pervades engineering design practice, research, and education. There has been a significant effort in understanding similarity in cognitive science, and some recent efforts on quantifying the similarity of design problems in the engineering design community. However, there is a lack of approaches for measuring similarity in engineering design that embody the characteristics identified in cognitive science, and accounts for the nature of design activities, particularly in the embodiment design phase where scientific knowledge plays a significant role. To address this gap, we present an approach for measuring the similarity among design problems. The approach consists of (i) modeling knowledge using probabilistic graphical models, (ii) modeling the functional mapping between design characteristics and the performance measures relevant in a particular context, and (iii) modeling the dissimilarity using KL-divergence in the performance space. We illustrate the approach using an example of a parametric shaft design for fatigue, which is typically a part of mechanical engineering design curricula, and test the validity of the approach using an experiment study involving 167 student subjects. The results indicate that the proposed approach can capture the well-documented characteristics of similarity, including directionality, context dependence, individual-specificity, and its dynamic nature. The approach is general enough that it can be extended further for assessing the similarity of design problems for analogical design, for assessing the similarity of experimental design tasks to real design settings, and for evaluating the similarity between design problems in educational settings.

Abstract The Honeycomb structure is one of the most common natural structures used in sandwich panel cores. The Enamel structure’s mechanical properties were compared to the Honeycomb structure’s mechanical properties to investigate if the Enamel structure can improve the compressive strength, stiffness and energy absorption capabilities of sandwich panel cores and potentially replace the common Honeycomb structure. Also, the optimal cellular configurations for the Honeycomb and Enamel structures were explored. Indeed, it was found the Enamel structure can potentially replace the Honeycomb structure and a wall thickness of 1.2 mm and a wall length/cell radius of 8.14 mm will maximize the natural structures mechanical properties. Furthermore, it was found that both the natural structures have good compressive strength. Therefore, the natural structures with their optimal cellular configurations were integrated into a novel automobile floor mat to ensure the mat possesses good compressive strength to resist failure or permanent deformation. Moreover, the novel automobile floor mat has a design feature that offers an efficient debris capturing and removal system that adds value to the automobile floor mat.

Abstract:

The second half of the 20th century brought to light the consequences of human activity, when Humanity was confronted with demiurgical complexes and realized that the planet Earth was not only nature, but a complex system that today could no longer be operated by traditional methods and logic. While until the middle of the 20th century man used natural resources only to meet his needs, the 21st century poses new challenges for mankind to manage the consequences of human activities and to use them rationally and sustainably. The paper presents a study aimed at assessing the potential of ecosystem services development in the Nemunas Delta and anticipating their development directions. As a result of the research, the possible development directions of the Elderships were presented. It was done in two scenarios. The research was carried out in six municipality subdivisions (elderships) of the Nemunas Delta area in the framework of the Lithuanian Science Council project ‘Interaction of ecosystem services and human activities in the context of climate change’. Preparation of this paper was supported by funding from European Social Fund (project No 09.3.3-LMT-K-712-01-0178) under the grant agreement with the Research Council of Lithuania (LMTLT).

Abstract:

The objective of this paper is to qualitatively assess the inadequacies of the current manner of tool wear quantification and consequently to suggest/develop a more comprehensive approach to machining tool wear characterization. Traditional parameters used for tool wear representation such as flank and crater wear are no longer self-sufficient to satisfactorily represent the wear of the complex geometric profiles of more recent cutting tools. These complexities in tool geometries are all the more pronounced when catering to difficult-to-machine materials such as titanium and its alloys. Hence, alternatives to traditional tool wear assessment parameters are briefly explored and a suitable one is selected, that will help understand the very nature of the evolving wear profile itself from a three dimensional standpoint. The assessment methodology is further developed and standardized and suggestions for future use and development provided. The measurement system is evaluated using a gauge repeatability and reproducibility (R&R) study as well. The method is deployed for assessing tool wear during the machining of Ti-6Al-4V at selected process conditions for validation purposes. Further, concepts such as the M-ratio and its derivatives are developed to quantify the efficiency of the cutting tool during each pass as a function of time at a theoretically constant material removal rate (MRR).

Abstract:

Calculating scour potential in a stream or river is as much a geomorphological art as it is an exact science. The complexity of stream hydraulics and heterogeneity of river-bed materials makes scour predictions in natural channels uncertain. Uncertain scour depths near high-hazard flood-risk zones and flood-risk management structures lead to over-designed projects and difficult flood-risk management decisions. This Regional Sediment Management technical report presents an approach for estimating scour by providing a decision framework that future practitioners can use to compute scour potential within a riverine environment. This methodology was developed through a partnership with the US Army Engineer Research and Development Center, Hydrologic Engineering Center, and St. Paul District in support of the Lower American River Contract 3 project in Sacramento, CA.
