Reconsidering the Role of Research Method Guidelines for Qualitative, Mixed-methods, and Design Science Research
2019
Guidelines for different qualitative research genres have been proposed in information systems (IS). As these guidelines are outlined for conducting and evaluating good research, studies may be denied publication simply because they do not follow a prescribed methodology. This can result in “checkbox” compliance, where the guidelines become more important than the study. We argue that guidelines can only be used to evaluate what good research is if there is evidence that they lead to certain good research outcomes. Currently, the guidelines do not present such evidence. Instead, when it is presented, the evidence is often an authority argument or evidence of popularity with usability exampl…
Search for decays of the Z0 into a photon and a pseudoscalar meson
1990
Abstract A search is reported for decays of the Z 0 into π 0 γ , ηγ and η ′ (958) γ in e + e − collisions using data collected during a scan around the Z 0 mass. In order to search for π 0 γ final states, in which the two photons from the π 0 decay are unresolved, the production of pairs of high-energy electromagnetic clusters is studied. The data are compared with the expectations from the pure QED process e + e − → γγ , and a 95% confidence level upper limit on the branching ratio of the Z 0 into π 0 γ of 4.9 × 10 −4 is derived. For η′γ, the decay modes of the mesons that contain two charged particles are largely free from QED background. These modes are used to place upper limits of 4.6 …
The influence of preparation methodology on the concentrations of heavy metals in Pleurozium schreberi moss samples prior to use in active biomonitor…
2020
AbstractActive biomonitoring is used to assess environmental pollution of elements such as heavy metals by indicator species such as mosses. They are used, among others, in urbanized areas where no indicator species are found. In such study areas, mosses collected from sites considered to be ecologically clean shall be exposed. In this context, it is very important to prepare the mosses properly before the exposure, so that the information received about the condition of the environment is reliable. In 2018, studies were conducted in the forested areas of southern Poland—in Opolskie Province. Pleurozium schreberi mosses were used in these studies. Atomic absorption spectrometry with flame a…
PROMOTING OF SELF-DIRECTED LEARNING IN COOPERATION WITH THE PARENTS FOR CHILDREN IN THE PRESCHOOL AGE
2015
Successful learning process in pre-school requires collaboration between children, educators and parents, whose primary goal is individual understanding of each child to promote his academic performance and personal development as a whole. This paper shows a pre-scientific and theoretical background of self-directed learning in preschool, as well as developed and theoretically substantiated child initiative research method "New friend". Particular attention is given to the promotion of the child's initiative, which is crucial in the process of self-directed learning. The empirical study of children's initiatives shows analysis of collaboration with the parents. A qualitative study reveals p…
An evaluation of the environmental factors for supply chain strategy decisions using grey systems and composite indicators
2020
[EN] The purpose of this work is to assess the importance of environmental factors in a supply chain with four partners as a preliminary step to select the competitive strategies and objectives. To achieve this purpose, a real case study was carried out in a footwear supply chain, in which two approaches were used: the grey system theory and uncertainty analysis tools for composite indicators. In order to validate both approaches, a seven-phase research methodology was developed and applied to our case study. In addition, the priorization of environmental factors was calculated individually for each partner. The results allow managers to establish the competitive strategy that best suits th…
Therapists’ Responses for Enhancing Change Through Dialogue: Dialogical Investigations of Change
2016
The point of view on research represented here is based on a dialogical framework. Our emphasis is on understanding the contribution of the therapists to the process of change. We conceptualize therapeutic conversation as a dialogical activity. In using the research method The Dialogical Investigation of Happenings of Change (DIHC) the focus is on how therapists participate and answer from a specific position of “responsive responsibility.” In this chapter our aim is twofold: (1) to present a method for conducting a dialogical analysis of couple sessions and (2) to track detailed sequences of events of change. To make sense of the details of this process, we use Bakhtinian concepts includin…
Impact evaluation of EU funds: Examples in infrastructure projects
2011
Being one of investment areas within EU Cohesion policy the sector of public infrastructure frequently faces the issue of efficiency. This issue largely arises from the lack of theoretical and practical concepts on how the evaluation techniques could achieve rigorous estimations of the investment impact on the current processes in the sector. The present paper seeks to contribute to these discussions by defining crucial problems in developing rigorous estimations relevant to public infrastructure projects and setting the assumptions. The research method is comparative and logical analysis of the theoretical concepts, methods and conclusions, published in scientific literature including poli…
Instruction-based clinical eye-tracking study on the visual interpretation of divergence : how do students look at vector field plots?
2018
Relating mathematical concepts to graphical representations is a challenging task for students. In this paper, we introduce two visual strategies to qualitatively interpret the divergence of graphical vector field representations. One strategy is based on the graphical interpretation of partial derivatives, while the other is based on the flux concept. We test the effectiveness of both strategies in an instruction-based eye-tracking study with N = 41 physics majors. We found that students’ performance improved when both strategies were introduced (74% correct) instead of only one strategy (64% correct), and students performed best when they were free to choose between the two strategies (88…

Respecto al análisis documental, se presentan hallazgos sobre revistas más productivas, autores e instituciones con mayor actividad investigadora en este campo y metodología de investigación utilizada en los estudios encontrados. Además, se hace un análisis cualitativo centrado en el contenido de los 4 tem…
Operational Definition of Serious Mental Illness: Heterogeneity in a Review of the Research on Quality-of-Life Interventions
2020
BACKGROUND: An operational definition of serious mental illness (SMI) with well-defined inclusion criteria allows the identification of the most vulnerable individuals and secures resources to meet their needs and develop social programs for their treatment, rehabilitation, and recovery. In addition, the contents of a clinical construct such as SMI have an impact on both the development and the clinical application of the research results. However, currently, different ways of operationalizing the definition of SMI coexist. AIMS: The aim of this review was to explore whether unanimity exists in the operationalization of SMI definitions in quality-of-life interventions research. METHODS: A r…
