The concept of physical and chemical change is far from being the clearest and most self-explanatory concept in the world. If a number of chemists are asked to define physical and chemical change, there may well appear to be a fair degree of uniformity in their answers, until a few examples are suggested. When chemists are asked to place a variety of changes into the category of physical or chemical change, then differences inevitably arise. It is not difficult to demonstrate this by viewing school textbooks and articles about the topic. In spite of this, physical and chemical change is still taught in most in most secondary school courses. The problem arises from the definition and the historical layers of meaning that have grown around the concept, almost by accretion, without teachers being aware of their significance. The purpose of this paper is to describe the answers given by experienced educators to a questionnaire, which attempted to find out what the views of science educators/chemists worldwide about physical and chemical change now are. Four appendixes present: (1) List of Respondents; (2) List of Questionnaires Returned; (3) Physical and Chemical Change: An Information Sheet; and (4) Full Questionnaire: Interview Protocol or Basis for Written Response.

We are delighted to welcome you to the International Psychological Applications Conference and Trends (InPACT) 2016, taking place in Lisbon, Portugal, from 30 of April to 2 of May, 2016. Psychology, nowadays, offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and behavioral standpoints), from this academic and practical scientific discipline, is aimed ultimately to benefit society. This International Conference seeks to provide some answers and explore the several areas within the Psychology field, new developments in studies and proposals for future scientific projects. The goal is to offer a worldwide connection between psychologists, researchers and lecturers, from a wide range of academic fields, interested in exploring and giving their contribution in psychological issues. The conference is a forum that connects and brings together academics, scholars, practitioners and others interested in a field that is fertile in new perspectives, ideas and knowledge. There is an extensive variety of contributors and presenters, which can supplement the view of the human essence and behavior, showing the impact of their different personal, academic and cultural experiences. This is, certainly, one of the reasons there are nationalities and cultures represented, inspiring multi-disciplinary collaborative links, fomenting intellectual encounter and development. InPACT 2016 received 332 submissions, from 37 different countries, reviewed by a double-blind process. Submissions were prepared to take form of Oral Presentations, Posters, Virtual Presentations and Workshops. It was accepted for presentation in the conference 96 submissions (29% acceptance rate). The conference also includes: (1) A keynote presentation from Prof. Dr. Richard Bentall (Institute of Psychology, Health & Society of the University of Liverpool, United Kingdom); (2) Three Special Talks, one from Emeritus Professor Carlos Amaral Dias (University of Coimbra, Director of Instituto Superior Miguel Torga, Vice-President of the Portuguese Association of Psychoanalysis and Psychoanalytic Psychotherapy, Private practitioner of psychiatry and psychoanalysis, Portugal) and Prof. Clara Pracana (Full and Training member of the Portuguese Association of Psychoanalysis and Psychoanalytic Psychotherapy, Portugal), another from Emeritus Professor Michael Wang (University of Leicester, United Kingdom), and a third one from Dr. Conceição Almeida (Founder of the Portuguese Association of Psychoanalysis and Psychoanalytical Psychotherapy, and Vice-President of the Board. Member of the Teaching Committee, Portugal); (3) An Invited Talk from Dr. Ana Vasconcelos (SAMS--Serviços de Assistência Médico-Social do Sindicato dos Bancários de Sul e Ilhas, founding member of the Portuguese Association of Psychoanalysis and Psychoanalytic Psychotherapy, and member of NPA-Neuropshycanalysis Association, Portugal). Thus, we would like to express our gratitude to all our invitees. This volume is composed by the abstracts of the International Psychological Applications Conference and Trends (InPACT 2016), organized by the World Institute for Advanced Research and Science (W.I.A.R.S.). This conference addresses different categories inside Applied Psychology area and papers fit broadly into one of the named themes and sub-themes. To develop the conference program six main broad-ranging categories had been chosen, which also cover different interest areas: (1) In CLINICAL PSYCHOLOGY: Emotions and related psychological processes; Assessment; Psychotherapy and counseling; Addictive behaviors; Eating disorders; Personality disorders; Quality of life and mental health; Communication within relationships; Services of mental health; and Psychopathology.

The proceedings contain the results of the research and developments conducted by authors who focused on what they are passionate about: to promote growth in research methods intimately related to Psychology and its applications. It includes an extensive variety of contributors and presenters by sharing their different personal, academic and cultural experiences. Authors will be invited to publish extended contributions for a book to be published by inScience Press. We would like to express thanks to all the authors and participants, the members of the academic scientific committee, partners and, of course, to the organizing and administration team for making and putting this conference together.

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a fast pace and affecting academia and professional practice in many ways. Paradigms such as just-in-time learning, constructivism, student-centered learning and collaborative approaches have emerged and are being supported by technological advancements such as simulations, virtual reality and multi-agents systems. These developments have created both opportunities and areas of serious concerns. This conference aimed to cover both technological as well as pedagogical issues related to these developments. The IADIS CELDA 2012 Conference received 98 submissions from more than 24 countries. Out of the papers submitted, 29 were accepted as full papers. In addition to the presentation of full papers, short papers and reflection papers, the conference also includes a keynote presentation from internationally distinguished researchers. Individual papers contain figures, tables, and references.
