The Impact

This study was conducted to analyze the students 'initial and final understanding after the application of JITT with 3D animation, to identify students' responses and arguments, and to determine the impact of using JITT with 3D animation. This research involved 43 students of the 6th semester of the 2019-2020 academic year of the Physics Education study program of the Universitas PGRI Kanjuruhan Malang who took solid state physics course. Students' initial and final understanding was analyzed through responses and arguments presented during the pretest, while the impact of JITT application with 3D animation was analyzed based on the results of the pretest and posttest as well as student responses during the learning process expressed through short interviews and discussions. The qualitative and quantitative data generated from the mixed-method approach were analyzed simultaneously. The results show that the students understand that the atomic radius for all the different crystal lattices is the same, namely a/2. This was awakened by an early understanding of the general definition of the radius. However, after following the JITT stages with 3D animation, their understanding changed that the atomic radius of each crystal lattice is different in length. In addition, the results of statistical analysis showed that there was a very significant increase in the students' mastery of concepts from an average of 26.9 to 96.7. Meanwhile, the N-gain value is very high, namely 0.96 in the very effective category, which illustrates that JITT with 3D animation has had a high impact on students' understanding of atomic radius in the concept of crystal geometry.

Purpose This paper aims to propose a set of quantitative statistical indicators for measuring the scientific relevance of research groups and researchers, based on high-impact open-access digital production repositories. Design/methodology/approach An action research (AR) methodology is proposed in which research is associated with the practice; research informs practice and practice is responsible for informing research in a cooperative way. AR is divided into five phases, beginning with the definition of the problematic scenario and an analysis of the state of the art and ending with conducting tests and publishing the results. Findings The proposed indicators were used to characterise group and individual output in a major public university in south-eastern Mexico. University campuses hosting a large number of high-impact research groups. These indicators were very useful in generating information that confirmed specific assumptions about the scientific production of the university. Research limitations/implications The data used here were retrieved from Scopus and open access national repository of Mexico. It would be possible to use other data sources to calculate these indicators. Practical implications The system used to implement the proposed indicators is independent of any particular technological tool and is based on standards for metadata description and exchange, thus facilitating the easy integration of new elements for evaluation. Social implications Many organisations evaluate researchers according to specific criteria, one of which is the prestige of journals. Although the guidelines differ between evaluation bodies, relevance is measured based on elements that can be adapted and where some have greater weight than others, including the prestige of the journal, the degree of collaboration with other researchers and individual production, etc. The proposed indicators can be used by various entities to evaluate researchers and research groups. Each country has its own organisations that are responsible for evaluation, using various criteria based on the impact of the publications. Originality/value The proposed indicators assess based on the importance of the types of publications and the degree of collaborations. However, they can be adapted to other similar scenarios.

The Impact

Strengthening ecopreneurship plays an important role in preparing students for success in the life and career of students, but this skill is not well trained in learning physics. Therefore, the purpose of this study was to analyze the impact of environment-based physics learning on students' mastery of concepts and ecopreneurship. This research is a quasi experimental research with one group pretest and posttest design. The research subjects were 29 students of the physics education study program, Surabaya State University, Indonesia, who programmed basic physics courses. The data collection technique used a conceptual mastery test instrument and ecopreneurship. The data analysis technique used the Kolmogorov-Smirnov test, Paired t-test, Wilcoxon test, and N-Gain. The results showed a significant increase in students' mastery of concepts and ecopreneurship at α = 5%, with mean N-gain of 0.63 and 0.60, respectively, within the moderate criteria. Thus, environment-based physics learning has a significant impact on increasing student mastery of concepts and ecopreneurship.

Considerations Concerning the Impact of Propensities on Basic Macroeconomic Occurrences In the article theoretical deliberations relating to impact of propensities on basic macroeconomic phenomena were presented. A general definition of propensity was discussed. The influence of propensity for consumption, propensity for investment and propensity for thesaurization on national income, interest rates, consumption expenditures, investments and money supply was analyzed. Derivatives that make it possible to identify quantitative effects of propensities were introduced. On the basis of the discussed Keynesian model it is possible to say that the propensity to consume increases interest rate and national income, the propensity to invest makes investments, national income and interest rates higher and the propensity for thesaurization could increase interest rates by lowering money supply.

The Impact

The aim of this short Commentary is to convey some thoughts and concerns that have arisen after reading the excellent articles included in this Special Issue. The focus will be on three particular points: (a) The differences that seem to exist, not so much regarding the general definition of therapeutic alliance, but rather with respect to the identification of the specific characteristics of this phenomemon and the factors that shape it. (b) The need to understand therapeutic alliance after taking into account the complex interactions that take place between several biological, psychological and social factors. Finally, (c) the impact of recent advancements, such as the great innovations in digital technology and health care, on therapeutic alliance. In any case, it is certain that our perception of therapeutic alliance will continue to evolve and change in the future.

Counseling Practices

Schizophrenia, with its various aspects that are as yet as unexplainable and which causes those suffering from it to move away from relationships and reality, is a severe psychiatric disorder that usually deteriorates thinking and behavior from an early age. A general definition of schizophrenia has been mentioned for the purpose of this study without describing the types of schizophrenia in detail. The main axis of the study is what role spirituality may have in increasing schizophrenic patients’ well-being, which is the last step in the model for their medical treatment. A lack of deterioration in patients’ consciousness and short-term memory is very important in order for them to be able to understand the therapeutic practices; the study discusses spiritual counseling practices that can be studied with schizophrenic patients who have no problems in these areas. The study evaluates the concept of insight in schizophrenia patients from different perspectives and includes spiritual counseling practices that can be done with schizophrenia patients possessing high levels of insight. The study continues by examining which individual spiritual counseling practices are possible for patients with schizophrenia and presents the example of group counseling over spiritual counseling practices for patients with schizophrenia as well as which counseling practices can be done for schizophrenic patients and their families. The main aim of this study is to present to clinicians, psychologists, and psychological counselors working in the field a general review of the literature on studies that have examined the relationship between schizophrenia and spirituality and to give them ideas into how to integrate spiritual counseling practices into the process while working with schizophrenia patients and their relatives.

The Impact

Assessing the ecological and economic impacts of non-native species is crucial to providing managers and policymakers with the information necessary to respond effectively. Most non-native species have minimal impacts on the environment in which they are introduced, but a small fraction are highly deleterious. The definition of ‘damaging’ or ‘high-impact’ varies based on the factors determined to be valuable by an individual or group, but interpretations of whether non-native species meet particular definitions can be influenced by the interpreter’s bias or level of expertise, or lack of group consensus. Uncertainty or disagreement about an impact classification may delay or otherwise adversely affect policymaking on management strategies. One way to prevent these issues would be to have a detailed, nine-point impact scale that would leave little room for interpretation and then divide the scale into agreed upon categories, such as low, medium, and high impact. Following a previously conducted, exhaustive search regarding non-native, conifer-specialist insects, the authors independently read the same sources and scored the impact of 41 conifer-specialist insects to determine if any variation among assessors existed when using a detailed impact scale. Each of the authors, who were selected to participate in the working group associated with this study because of their diverse backgrounds, also provided their level of expertise and uncertainty for each insect evaluated. We observed 85% congruence in impact rating among assessors, with 27% of the insects having perfect inter-rater agreement. Variance in assessment peaked in insects with a moderate impact level, perhaps due to ambiguous information or prior assessor perceptions of these specific insect species. The authors also participated in a joint fact-finding discussion of two insects with the most divergent impact scores to isolate potential sources of variation in assessor impact scores. We identified four themes that could be experienced by impact assessors: ambiguous information, discounted details, observed versus potential impact, and prior knowledge. To improve consistency in impact decision-making, we encourage groups to establish a detailed scale that would allow all observed and published impacts to fall under a particular score, provide clear, reproducible guidelines and training, and use consensus-building techniques when necessary.

Nominal Variables

Elicitation, estimation and exact inference in Bayesian Networks (BNs) are often difficult because the dimension of each Conditional Probability Table (CPT) grows exponentially with the increase in the number of parent variables. The Noisy-MAX decomposition has been proposed to break down a large CPT into several smaller CPTs exploiting the assumption of causal independence, i.e., absence of causal interaction among parent variables. In this way, the number of conditional probabilities to be elicited or estimated and the computational burden of the joint tree algorithm for exact inference are reduced. Unfortunately, the Noisy-MAX decomposition is suited to graded variables only, i.e., ordinal variables with the lowest state as reference, but real-world applications of BNs may also involve a number of non-graded variables, like the ones with reference state in the middle of the sample space (double-graded variables) and with two or more unordered non-reference states (multi-valued nominal variables). In this paper, we propose the causal independence decomposition, which includes the Noisy-MAX and two generalizations suited to double-graded and multi-valued nominal variables. While the general definition of BN implicitly assumes the presence of all the possible causal interactions, our proposal is based on causal independence, and causal interaction is a feature that can be added upon need. The impact of our proposal is investigated on a published BN for the diagnosis of acute cardiopulmonary diseases.

The Impact

Entities such as commercial insurance companies are obliged to create technical provisions in order to fulfill their activities. Technical provisions are used to cover liabilities of commercial insurance companies arising from insurance and reinsurance activities. The principal aim of this paper is to determine the impact of the creation and use of technical provisions for some important items of the financial statements, which are liabilities, a balance sheet, profit and an income tax base. A prerequisite to fulfill the objective of the paper is to analyze the accounting legislation for technical provisions in an insurance company. The intention of the presented paper can be divided according to its conception into two parts. The first part of the paper is devoted to methodological aspects in relation to the general definition of the accounting principles and their importance in the accounting of commercial insurance companies. The second part deals with the methodological procedure of the accounting of the creation and use of technical provisions and the specifics of how they are reported in the financial statements of commercial insurers. Conclusions of the paper show contemporary issues in the analyzed area in the context of the financial crisis.

Independence Relations

The notion of independence is central in many information processing areas, such as multiple criteria decision making, databases, or uncertain reasoning. This is especially true in the later case, where the success of Bayesian networks is basically due to the graphical representation of independence they provide. This paper first studies qualitative independence relations when uncertainty is encoded by a complete pre-order between states of the world. While a lot of work has focused on the formulation of suitable definitions of independence in uncertainty theories our interest in this paper is rather to formulate a general definition of independence based on purely ordinal considerations, and that applies to all weakly ordered settings. The second part of the paper investigates the impact of the embedding of qualitative independence relations into the scale-based possibility theory. The absolute scale used in this setting enforces the commensurateness between local pre-orders (since they share the same scale). This leads to an easy decomposability property of the joint distributions into more elementary relations on the basis of the independence relations. Lastly we provide a comparative study between already known definitions of possibilistic independence and the ones proposed here.

ABSTRACTThis paper focuses on the question of how to resolve disagreement and uses the Lehrer-Wagner model as a formal tool for investigating consensual decision-making. The main result consists in a general definition of when agents treat each other as epistemic peers (Kelly 2005; Elga 2007), and a theorem vindicating the “equal weight view” to resolve disagreement among epistemic peers. We apply our findings to an analysis of the impact of social network structures on group deliberation processes, and we demonstrate their stability with the help of numerical simulations.
