The importance of mutual understanding between external accountants and owner-managers of SMEs
This study investigates the perspective of the ownerâmanager of a small or mediumâsized enterprise (SME) on the importance of mutual understanding with an external accountant. Mutual understanding means that the ownerâmanager understands what the accountant is saying and feels understood by the accountant. The results, based on 310 completed surveys of Belgian ownerâmanagers, show that ownerâmanagers who have a high level of mutual understanding use the advice of their external accountant more extensively. This is in turn positively linked to the financial health of an SME. Furthermore, several drivers that enable the establishment of a high level of mutual understanding are explored. Ownerâmanagers with a high level of mutual understanding consider their accountant as a strategic partner, experience a high level of proactive behaviour with them, have a higher frequency of formal contact, and perceive informal contact as important. External accountants should consider these opportunities in their client management and training of internal staff. Education of clients and openness also seem very important, as the level of a client's accounting knowledge, the number of accounting topics ownerâmanagers deal with, and transparency towards the accountant are significantly positively related to mutual understanding
Normas percibidas por estudiantes peruanos acerca de sus pares y el uso de drogas
O objetivo deste estudo foi avaliar a diferença entre as normas percebidas pelos estudantes universitĂĄrios, com idade entre 18 e 24 anos, sobre o uso de drogas pelos seus pares e o uso de drogas relatado pelos prĂłprios estudantes em cursos da ĂĄrea da saĂșde. Foi usado o mĂ©todo transversal, baseado em censo realizado atravĂ©s de questionĂĄrio, preenchido pelos prĂłprios estudantes, sem identificação. O nĂșmero de participantes foi de 306 (82%). Como resultados obteve-se: a proporção de estudantes que utilizou drogas no Ășltimo ano foi de 51,3% para o tabaco, 90,8% para o ĂĄlcool, 5,9% para a maconha e 0,7% para a cocaĂna. Diferença entre as normas percebidas e o uso de drogas foi observada para o tabaco (70% vs 51,3%), maconha (10% vs 5.9%) e cocaĂna (8,3% vs 0,7%). Conclui-se que os estudantes universitĂĄrios apresentaram estimativa aumentada sobre o consumo de tabaco, maconha e cocaĂna entre seus pares.El objetivo de este estudio fue estimar la diferencia entre las normas percibidas sobre el uso de drogas por sus pares y el uso real de drogas entre universitarios, entre 18 y 24 años, de las ĂĄreas de salud. Se trata de un estudio transversal, basado en un censo y en un cuestionario anĂłnimo y autoaplicado. Participaron 306 estudiantes (82%). La proporciĂłn del consumo, en el Ășltimo año, fue de 51,3% para el tabaco, 90,8% para el alcohol, 5,9% para la marihuana y 0,7% para la cocaĂna. Se observĂł una diferencia entre la norma percibida de consumo y la proporciĂłn de uso real informado para el tabaco (70% vs. 51.3%), marihuana (10% vs. 5.9%) y cocaĂna (8.3% vs. 0.7%). Se concluye que los universitarios sobrestiman el consumo de tabaco, marihuana y cocaĂna de sus pares.Objective: to evaluate the difference between perceived norms about drug use among peer and actual drug use as reported by the same university students. The students were between 18 and 24 years old and attended health courses. Method: cross-sectional study based on a survey, using an anonymous questionnaire filled out by the students. RESULTS: There were 306 participants. Senior students used drugs as follows: 51.3% used tobacco, 90.8% used alcohol, 5.9% used marijuana, and 0.7% used cocaine. Differences were observed between perceived norms and actual drug use for tobacco (70% vs. 51.3%), marijuana (10% vs. 5.9%) and cocaine (8.3% vs. 0.7%). CONCLUSIONS: university students presented an overestimated rate for the use of tobacco, marijuana and cocaine among their peers
The Case for Dynamic Models of Learners' Ontologies in Physics
In a series of well-known papers, Chi and Slotta (Chi, 1992; Chi & Slotta,
1993; Chi, Slotta & de Leeuw, 1994; Slotta, Chi & Joram, 1995; Chi, 2005;
Slotta & Chi, 2006) have contended that a reason for students' difficulties in
learning physics is that they think about concepts as things rather than as
processes, and that there is a significant barrier between these two
ontological categories. We contest this view, arguing that expert and novice
reasoning often and productively traverses ontological categories. We cite
examples from everyday, classroom, and professional contexts to illustrate
this. We agree with Chi and Slotta that instruction should attend to learners'
ontologies; but we find these ontologies are better understood as dynamic and
context-dependent, rather than as static constraints. To promote one
ontological description in physics instruction, as suggested by Slotta and Chi,
could undermine novices' access to productive cognitive resources they bring to
their studies and inhibit their transition to the dynamic ontological
flexibility required of experts.Comment: The Journal of the Learning Sciences (In Press
Methods for the thematic synthesis of qualitative research in systematic reviews
<p>Abstract</p> <p>Background</p> <p>There is a growing recognition of the value of synthesising qualitative research in the evidence base in order to facilitate effective and appropriate health care. In response to this, methods for undertaking these syntheses are currently being developed. Thematic analysis is a method that is often used to analyse data in primary qualitative research. This paper reports on the use of this type of analysis in systematic reviews to bring together and integrate the findings of multiple qualitative studies.</p> <p>Methods</p> <p>We describe thematic synthesis, outline several steps for its conduct and illustrate the process and outcome of this approach using a completed review of health promotion research. Thematic synthesis has three stages: the coding of text 'line-by-line'; the development of 'descriptive themes'; and the generation of 'analytical themes'. While the development of descriptive themes remains 'close' to the primary studies, the analytical themes represent a stage of interpretation whereby the reviewers 'go beyond' the primary studies and generate new interpretive constructs, explanations or hypotheses. The use of computer software can facilitate this method of synthesis; detailed guidance is given on how this can be achieved.</p> <p>Results</p> <p>We used thematic synthesis to combine the studies of children's views and identified key themes to explore in the intervention studies. Most interventions were based in school and often combined learning about health benefits with 'hands-on' experience. The studies of children's views suggested that fruit and vegetables should be treated in different ways, and that messages should not focus on health warnings. Interventions that were in line with these suggestions tended to be more effective. Thematic synthesis enabled us to stay 'close' to the results of the primary studies, synthesising them in a transparent way, and facilitating the explicit production of new concepts and hypotheses.</p> <p>Conclusion</p> <p>We compare thematic synthesis to other methods for the synthesis of qualitative research, discussing issues of context and rigour. Thematic synthesis is presented as a tried and tested method that preserves an explicit and transparent link between conclusions and the text of primary studies; as such it preserves principles that have traditionally been important to systematic reviewing.</p
Using resource graphs to represent conceptual change
We introduce resource graphs, a representation of linked ideas used when
reasoning about specific contexts in physics. Our model is consistent with
previous descriptions of resources and coordination classes. It can represent
mesoscopic scales that are neither knowledge-in-pieces or large-scale concepts.
We use resource graphs to describe several forms of conceptual change:
incremental, cascade, wholesale, and dual construction. For each, we give
evidence from the physics education research literature to show examples of
each form of conceptual change. Where possible, we compare our representation
to models used by other researchers. Building on our representation, we
introduce a new form of conceptual change, differentiation, and suggest several
experimental studies that would help understand the differences between
reform-based curricula.Comment: 27 pages, 14 figures, no tables. Submitted for publication to the

Mood and transient cardiac dysfunction in everyday life
Emotion in daily life may be associated with transient myocardial ischemia, ventricular tachycardia and impaired autonomic function in cardiac patients, but the precise temporal sequence is unclear. Eighty-eight patients with suspected coronary artery disease underwent 24-h electrocardiographic monitoring, and affect was measured with the Day Reconstruction Method. Thirteen patients (15%) experienced one or more episodes of ST depression or ventricular tachycardia, nine of whom provided concurrent mood data. Mood and heart rate variability were analyzed for the 15Â min before, during, and 15Â min after each ST depression/ventricular tachycardia episode, and were compared with control periods not associated with cardiac dysfunction. Patients reported more negative mood in the 15Â min preceding cardiac dysfunction compared with control periods (PÂ =Â 0.02). Heart rate increased in the 5Â min before cardiac dysfunction (PÂ =Â 0.005), whereas low frequency heart rate variability was reduced at onset but not before cardiac dysfunction (PÂ =Â 0.007). There were not changes in high frequency heart rate variability. This small study indicates that emotional state may contribute to vulnerability of cardiac dysfunction in everyday life

Citizenship Education and Liberalism: A State of the Debate Analysis 1990â2010
What kind of citizenship education, if any, should schools in liberal societies promote? And what ends is such education supposed to serve? Over the last decades a respectable body of literature has emerged to address these and related issues. In this state of the debate analysis we examine a sample of journal articles dealing with these very issues spanning a twenty-year period with the aim to analyse debate patterns and developments in the research field. We first carry out a qualitative analysis where we design a two-dimensional theoretical framework in order to systematise the various liberal debate positions, and make us able to study their justifications, internal tensions and engagements with other positions. In the ensuing quantitative leg of the study we carry out a quantitative bibliometric analysis where we weigh the importance of specific scholars. We finally discuss possible merits and flaws in the research field, as evidenced in and by the analysis

Family involvement and firmsâ establishment mode choice in foreign markets
Extant literature on foreign entry increasingly recognizes firmsâ heterogeneity as a potential reason for inconsistency in results on the establishment mode choice, i.e. whether and under which conditions firms should choose to enter a new country through a greenfield investment or an acquisition. Our study contributes to this debate by identifying family ownership and family involvement in management as potential powerful sources of such heterogeneity. Integrating international business studies with both corporate finance literature on family firms and recent contributions from the Socio Emotional Wealth perspective on family ownership, we claim that, due to greater risk aversion and lower access to information, the family involvement either in the firm ownership and management leads to a higher propensity towards greenfield initiatives (vs. acquisitions). However, we also find that such a propensity decreases with international experience especially in family-owned firms given the greater ability of professionalized management to overcome family-related concerns on making acquisitions. Our analysis on 1,045 foreign initiatives undertaken by 311 Italian family and non-family firms between 2003 and 2013 confirms our expectations â indicating family ownership as a significant driver of international business choices
