This textbook and reference outlines the fundamental principles of thermodynamics, emphasizing applications in geochemistry. The work is distinguished by its comprehensive, balanced coverage and its rigorous presentation. The authors bring years of teaching experience to the work, and have attempted to particularly address those areas where other texts on the subject have provided inadequate coverage. A thorough review of the necessary mathematics is presented early on, both as a refresher for those with a background in university calculus, and for the benefit of those coming to the subject for the first time. The text is written for students in advanced undergraduate or graduate-level geochemistry as well as for all researchers in this field.

Background and Purpose. There is a paucity of published literature regarding the correlation between faculty attributes and education program pass rates on the National Physical Therapy Examination (NPTE) particularly regarding the physical therapist assistant (PTA). The purpose of this study was to 1) determine if there is a relationship between faculty attributes in PTA educational programs and program outcomes on the NPTE for Physical Therapist Assistants (NPTE-PTA) and 2) construct a prediction model for PTA program outcomes based on faculty attributes. Subjects. The 233United States’ PTA programs accredited by the Commission on Accreditation in Physical Therapy Education (CAPTE) in 2006 were studied. Methods. Using a retrospective design, data were obtained regarding the PTA programs from the dataset of CAPTE’s PTA annual accreditation report and the Federation of State Boards of Physical Therapy’s pass rate database. Selected faculty attributes (designation of highest degree conferred, years of teaching experience, employment status, license designation [physical therapist or physical therapist assistant] and clinical specialization) were correlated to first time program pass rates. Backward deletion regression was used to predict the first time pass rate on the NPTE-PTA.Results. Based on data from 190/233 PTA programs, seven attributes had a statistically significant relationship to the outcomes on the NPTE-PTA. They were the number of: 1) full-time faculty; 2) adjunct faculty with an associate’s degree; 3) full-time faculty with a terminal degree; 4) core faculty with a terminal degree; 5) all faculty with a terminal degree 6) years of teaching experience of the full-time faculty; 7) years of teaching experience of the core faculty. Backward deletion regression analyses demonstrated an overall model of two combined predictor factors (full-time faculty years of teaching and full-time faculty terminal degree) that significantly predicted the first time pass rate on the NPTE-PTAaccounting for 6.5% of the variance. Discussion and Conclusion. Faculty attributes of the institutions providing PTAprograms are associated with first time pass rates of their graduates. This study provides a foundation for future studies by identifying some of the faculty attributes that relate to NPTE-PTA outcomes.

This essay is part of a wider research project that has introduced puppets into the drawing studio. Puppets are odd operators, and this is an unorthodox approach to drawing research. In this case, eccentricity is appropriate given that orthodoxies of skilfulness and good drawing are the subject of investigation. Unlike other contemporary practices that utilize puppetry as subject matter, motif and narrative device, this project invites draughtspuppets to make drawings. These draughtspuppets are distinct from automata and other drawing machines, and these distinctions are outlined. The paper focuses on the virtue and value of dexterity. In drawing and in puppet manipulation, dexterity brings scrutiny to the hands as the primary site of action and queries the relationship between ‘good hands’ and ‘good drawing’. The text begins by connecting traditions of dexterity, manipulation, drawing and puppetry before delving into the essence of puppets – their animism and (semi-)autonomy – and the tacit implications of dextrous hands. This article asks the question: can puppet ontologies expose the value of dexterity as a procedural component of (good) drawing? Connecting a range of puppet scholarship, the author’s interactions with the draughtspuppets and over 25 years of teaching experience, this article finally argues for the productive capacity of draughtspuppets to transform orthodox beliefs about the tenets of dexterity and good drawing. In the final passage, the motifs present in the draughtspuppets’ recent drawings are briefly analysed and correlated with this examination.

This article aims to study on the readiness of history teachers to inculcate historical thinking skills among students. This study focused on four aspects which includes 1) Procedural Knowledge, and 2) Pedagogical Knowledge. Thus, to achieve the purpose of the study, quantitative methods are used. Questionnaires were distributed to 30 history teachers in a secondary school in Batu Pahat district. The results showed that there were no significant differences between teachers who were trained to teach History and those who are not. However, there was a significant difference between teachers with ten years of teaching experience with the readiness of history teachers.

The current study investigates the beliefs held by science teachers on constructivism and a traditional approach in Qatar government primary schools. More specifically, it aims to investigate the challenges that science teachers experience during inquiry-based learning implementation. A web-based survey was conducted in order to collect data from grades 4 to 6 science teachers. A total of 112 science teachers responded and completed the survey on a voluntary basis. The results indicate that science teachers hold a higher beliefs in constructivism than traditional approach. A T-test and ANOVA analysis have showed that there is no significant differences between the beliefs of science teachers’ and their gender, level of education, and years of teaching experience. In addition, science teachers faced challenges in lesson planning, assessment, and teacher support.

This given article reveals the topicality not only of destructive, but also of constructive, as well as hybrid conflicts. Practically it has been done for the first time. It also describes the history of the formation of both foreign and domestic social conflictology. At the same time, the chronology of the development of the latter is restored and presented objectively, in full, taking into account the contribution of those researchers who actually stood at its origins. The article deals with the essence of the socio-psychological approach to understanding conflicts. The subject of social conflictology includes the regularities of their occurrence and manifestation at various levels, spheres and conditions, including normal, complicated and extreme ones. Social conflictology includes the theory and practice of diagnosing, resolving, and resolving social conflicts. It analyzes the difficulties that occur in defining the concept, structure, dynamics, and classification of social conflicts. Therefore, it is no accident that the most important task is to create a full-fledged theory of social conflicts. Without this, it is impossible to talk about effective settlement and resolution of social conflicts. Social conflictology is an integral part of conflictology. There is still a lot of work to be done, both in theory and in application, for its complete design. At present, there is an urgent need to develop conflict-related competence not only of professionals, but also for various groups of the population.

Coronavirus disease 2019 (COVID-19) is currently the most potent threat to educational systems, a crisis that may become disastrous. For the current study, a qualitative design within a case study tradition was implemented to investigate instructional barriers during COVID-19 faced by Indonesian teachers in Islamic boarding schools (Pesantren). Within this study, we applied a purposeful convenient sampling in which the access was obtained through communication with the principals of two Pesantren. Seven invited participants with more than ten years of teaching experience agreed to participate. Semi-structured interviews were addressed for data collection; each interview lasted from 40 to 50 min. The interviews were conducted in the participants’ mother tongue to provide an in-depth understanding of their perceptions, ideas, and arguments regarding instructional barriers during the COVID-19 outbreak. The thematic analysis revealed three major findings regarding the barriers; technological barriers, financial barriers, and pedagogical barriers affecting instructional activities in the two Pesantren. Based on the three themes, the development of a qualitative conceptual map of teachers’ instructional barriers was finalized. Recommendations are also proposed by the participants and the study for the betterment of Indonesian Islamic education facing future similar outbreaks.

Abstract This contribution intends to draw attention to one of the most significant monuments of medieval Ravenna: the church of Santa Maria in Porto Fuori, which was destroyed during the Second World War. Until now, scholars have focused on the pictorial cycle known through photographs and attributed to the painter Pietro da Rimini. However, the architecture of the building has not been the subject of systematic studies. For the first time, this essay reconstructs the fourteenth-century architectural structure of the church, the apse of which was rebuilt by 1314. The data that led to the virtual restitution of the choir and the related rood screen are the basis for new reflections on the accesses to the apse area, on the pilgrimage flows, and on the view of the frescoes.

The possible presence of very large petroleum and natural gas reserves in the area beneath the North Sea is currently the subject of intense investigation. If confirmed, as seems likely in at least some localities, this occurrence will raise legal problems of considerable interest and complexity. For the North Sea is not merely an oilfield covered by water: for centuries it has been one of the world's major fishery regions and the avenue to and from the world's busiest seaports. Thus all three of the present principal uses of the sea—fishing, navigation, and the exploitation of submarine resources—promise to meet for the first time on a large scale in an area where all are of major importance. The process of reconciling the various interests at stake will provide the first thoroughgoing test of the adequacy and acceptability of the general principles laid down in the 1958 Geneva Convention on the Continental Shelf and should add greatly to the practice and precedents available in this developing branch of the law. In the present article an attempt is made to review some of the geographical and economic considerations involved in the North Sea situation, to note some of the technical and legal developments that have already taken place, and to consider these elements in the light of the various interests and legal principles concerned.

What to teach the first-time student in a political science class? Perhaps more importantly, what to teach the undergraduate whose only experience with political science, and the formal study of politics, will be the introduction they receive in our classes?Owing to the peculiarities of our discipline, the “Introduction to Political Science” class is often just that: a tour through all the major gardens in the discipline, describing to students what is done among scholars and practicioners in the various fields, giving them an overall view of what we do, how we do it, and in the process perhaps making a case for the significance of our discipline, our research, and perhaps even the subject itself — politics.
