Communicating the new chemistry in 18th-century Portugal: Seabra’s Elementos de Chimica

In this paper, we analyse the aims, contents and impact of Seabra’s two-volume textbook – Elementos de Chimica (Elements of Chemistry) – published in 1788 and 1790. Seabra’s Elements of Chemistry does not conform to the characteristics usually ascribed to textbooks by traditional historiography, and in particular to textbooks published in the peripheries. Marking the arrival of the new chemistry in Portugal, in a period in which many still resisted Lavoisier’s chemistry, this textbook was a state of the art account written in Portuguese, interspersed with critical evaluations, original comments and novel contributions. Despite being the only Portuguese chemistry textbook written during this period, it had hardly any readers, even among its natural audience at the University of Coimbra.     

History of education in Brazil: the construction of a knowledge field

This article analyses the general characteristics of the construction of the field of history of education in Brazil. To do so, it highlights the existing historiography and aims to describe the process of institutionalisation of this knowledge field, which, in general terms, has been focused on the area of teacher training. Since the nineteenth century, however, it has also been possible to identify systematic historiographical efforts in Brazil that are not directly related to the school system, but rather to the teaching of and research into the history of education within Brazilian universities. The article addresses the organisation of the field, the ways in which it has been structured and the strategies of academic legitimisation employed to achieve this. These include the regular production of dissertations and doctoral theses, the publication of books and journals, academic events and the creation of research groups and scientific associations, through which research findings have found national and international circulation. This set of indicators creates conditions for an understanding of the expansion and reconfiguration of the field of history of education that began in the 1980s, as well as of the challenges this phenomenon presents to current historiography and teacher training in Brazil.     

PERSONNEL NEEDS IN SCHOOL PSYCHOLOGY: A 10‐YEAR FOLLOW‐UP STUDY ON PREDICTED PERSONNEL SHORTAGES

Concerns regarding whether a sufficient supply of school psychologists exists have been evident for decades. Studies have predicted that school psychology would face a critical personnel shortage that would peak in 2010, but continue into the foreseeable future. The current study is a 10‐year follow‐up investigation based on previously published personnel shortage projections. Data derived from the National Association of School Psychologists 2009–2010 national study were used to examine current personnel shortages as well as to project the extent to which personnel shortages are likely to continue. Findings indicate that the field of school psychology continues to experience a personnel shortage that will continue through 2025. Additionally, greater rates of retirements are projected for the field for school psychologists who are males, who possess a doctoral degree, and for university faculty. Analyses based on the U.S. Census Regions indicate that notable differences are likely to occur in the match between the supply of and demand for school psychologists based on geographical location. Implications are discussed relating to the recruitment and retention of school psychologists and to the services they deliver.     

Better communication = better relationships: Tips for caregivers

We all live in a social environment with others. Indeed, ... we desire and seek out relationships with others, and we have personal needs that can be satisfied only through interacting with other humans (Johnson, 1986). It is not possible to think of living without relating to other people, nor is it possible to develop satisfying relationships without some sort of communication. Communication skills are the tools, the means, the mechanism through which we develop our relationships. Just as a carpenter would not expect to produce a fine piece of furniture with a blunt saw, neither should we assume that we can develop productive relationships with other people, such as children and their parents, colleagues or professional associates, using inadequate or ineffective communication skills. Johnson (1986) suggested that interpersonal skills are learned just as any other skills are learned. However, simply having learned communication skills is not enough! We need to continually practice these skills and occasionally be reminded of their value for interacting with and developing relationships with others. This, therefore, is a small reminder that all of us, caregivers and parents alike, can do with sharpening up our style of communicating with others and learn to create better and more satisfying human relationships!Jillian Rodd is a psychologist who lectures at the School of Early Childhood Studies, University of Melbourne, Australia.

Independent Olympic Athletes and the Legitimacy of the International Olympic Committee in Resolving International Conflicts

Abstract

Over the last three centuries (nineteenth, twentieth, and twenty-first) humanity has been facing huge political and ideological conflicts, especially wars. For these reasons, it was seen how necessary it was to create global institutions that aimed to promote peace and reduce or stop conflicts of this magnitude. Therefore, an international institution had already brought on its premises the principles of international peace and reconciliation through sport: the International Olympic Committee (IOC). However, despite bringing together nations around peaceful ties in an international competition, the IOC and the Olympic Games event have always been affected by constant conflicts along their path in the twentieth century, emphasizing issues involving nationalities. Thereby, in a mediator posture of international conflicts and in an effort to reduce the subversions that surrounded it, the IOC, in the 1990s, created the delegation of Independent Olympic Athletes. Such a delegation consists of athletes who cannot represent their respective nationalities at the Olympics due to political factors and/or armament conflicts. This proposal of the IOC demonstrates its posture to avoid, minimize, and even cease ideological and political events that might interfere with the Olympics Games or the athletes participating in them.     

Improved determination of dynamic balance using the centre of mass and centre of pressure inclination variables in a complete golf swing cycle

Golf requires proper dynamic balance to accurately control the club head through a harmonious coordination of each human segment and joint. In this study, we evaluated the ability for dynamic balance during a golf swing by using the centre of mass (COM)–centre of pressure (COP) inclination variables. Twelve professional, 13 amateur and 10 novice golfers participated in this study. Six infrared cameras, two force platforms and SB-Clinic software were used to measure the net COM and COP trajectories. In order to evaluate dynamic balance ability, the COM–COP inclination angle, COM–COP inclination angular velocity and normalised COM–COP inclination angular jerk were used. Professional golfer group revealed a smaller COM–COP inclination angle and angular velocity than novice golfer group in the lead/trail direction (P < 0.01). In the normalised COM–COP inclination angular jerk, the professional golfer group showed a lower value than the other two groups in all directions. Professional golfers tend to exhibit improved dynamic balance, and this can be attributed to the neuromusculoskeletal system that maintains balance with proper postural control. This study has the potential to allow for an evaluation of the dynamic balance mechanism and will provide useful basic information for swing training and prevention of golf injuries.     

Assessing conditions to enhance student success: How six campuses got started

The Inventory for Student Engagement and Success (ISES) uses evidence from educationally effective institutions to help campuses gain a better understanding of their work with students. Campuses of varying sizes, with diverse missions, are using ISES to solve problems and improve educational practices.
