Data saturation is the most commonly employed concept for estimating sample sizes in qualitative research. Over the past 20 years, scholars using both empirical research and mathematical/statistical ...models have made significant contributions to the question: How many qualitative interviews are enough? This body of work has advanced the evidence base for sample size estimation in qualitative inquiry during the design phase of a study, prior to data collection, but it does not provide qualitative researchers with a simple and reliable way to determine the adequacy of sample sizes during and/or after data collection. Using the principle of saturation as a foundation, we describe and validate a simple-to-apply method for assessing and reporting on saturation in the context of inductive thematic analyses. Following a review of the empirical research on data saturation and sample size estimation in qualitative research, we propose an alternative way to evaluate saturation that overcomes the shortcomings and challenges associated with existing methods identified in our review. Our approach includes three primary elements in its calculation and assessment: Base Size, Run Length, and New Information Threshold. We additionally propose a more flexible approach to reporting saturation. To validate our method, we use a bootstrapping technique on three existing thematically coded qualitative datasets generated from in-depth interviews. Results from this analysis indicate the method we propose to assess and report on saturation is feasible and congruent with findings from earlier studies.
In this survey paper, by using variational methods, we are concerned with the qualitative analysis of solutions to nonlinear elliptic problems of the type (ProQuest: Formulae and/or non-USASCII text ...omitted) where Omega is a bounded or an exterior domain of dbl-struck R super(N) and q is a continuous positive function. The results presented in this paper extend several contributions concerning the Lane-Emden equation and we focus on new phenomena which are due to the presence of variable exponents.
This article addresses potential effects on reflexivity of researcher’s social position (e.g. gender, age, race, immigration status, sexual orientation), personal experiences, and political and ...professional beliefs. Because reflexivity is a major strategy for quality control in qualitative research, understanding how it may be impacted by the characteristics and experiences of the researcher is of paramount importance. Benefits and challenges to reflexivity under three types of researcher’s position are discussed and illustrated by means of case examples: (1) reflexivity when researcher shares the experience of study participants, (2) reflexivity when researcher moves from the position of an outsider to the position of an insider in the course of the study, and (3) reflexivity when researcher has no personal familiarity or experience with what is being studied. Strategies are offered for harvesting the benefits of researcher’s familiarity with the subject and for curbing its potentially negative effects. Directions for future research are suggested.
The aim of this research is to describe the process of pattern generalization based on the taxonomy for categorizing generalization i.e. relating, searching and extending. The subjects were the fifth ...and the sixth grade students of elementary school. Qualitative data were obtained from their written work when they solved the problems of patterns and from interviews. First, at the first stage, students were asked to solve a problem of pattern generalization and at the second stage, they were interviewed in order to find out whether they understood the process of generalization or not. The results showed that the students focused on two aspects when they were facing the problem of pattern generalization, that is, they focused on the number of squares in the figure without considering the shape of the figure and they focused on the shape of the figure by paying attention to the square in the middle and to the addition of square on each side of the figure. The result of this study also revealed that students who focused on the shape of the figure found it more easily to formulate its general rule.

We obtain classical string solutions on Formula omitted by applying the dressing method on string solutions with elliptic Pohlmeyer counterparts. This is realized through the use of the simplest ...possible dressing factor, which possesses just a pair of poles lying on the unit circle. The latter is equivalent to the action of a single Bäcklund transformation on the corresponding sine-Gordon solutions. The obtained dressed elliptic strings present an interesting bifurcation of their qualitative characteristics at a specific value of a modulus of the seed solutions. Finally, an interesting generic feature of the dressed strings, which originates from the form of the simplest dressing factor and not from the specific seed solution, is the fact that they can be considered as drawn by an epicycle of constant radius whose center is running on the seed solution. The radius of the epicycle is directly related to the location of the poles of the dressing factor.
This research takes the object of the Kenyah Dayak tribe's Sampek in pampang village in Samarinda which until now is still alive and developing in the midst of the hustle and bustle of the city of ...Samarinda. This research is more focused on finding data on the origin of the existence of the Kenyah Dayak tribe, the beliefs of the Kenyah Dayak tribe, the origin of the existence of Sampek music, the relationship between sampek music and the life of the Kenyah Dayak community in Pampang village, and how to play Sampek music. The research uses qualitative methods with descriptive analytical writing and uses an ethnomusicological approach. The results of the study revealed that the existence of Sampek music is closely related to the daily life of the Pampang Dalam people who until now still believe in the power of Bungan Malan as the ruler of the region. The creation of Sampek music is also inseparable from the existence of Lawe folklore which is represented in musical elements in sampek games

This study aimed to describe and explain the expression of the ethnic Osing culture in the folk song. The study used a qualitative design by utilizing a hermeneutic approach to understanding the ...meaning. Data were the text of Banyuwangi folk songs collected by document studies and interviews and analyzed by the following steps: data reduction, presentation, interpretation, and conclusion. This study understood the meaning under the level of semantic, reflective, and existential. The findings showed that the Banyuwangi folk songs expressed the ethnic Osing personality, social behavior, and environmental knowledge of the ethnic Osing. Osing people are simple, accepting of reality, obedient to their parents, careful in making decisions, humble, and have futuristic views. The social behavior of the Osing tribe includes getting along at work, maintaining togetherness in ritual traditions, caring for neighbors, and obeying ethics. Osing people know various types of animals, plants, and material objects that surround and fulfill their life needs. This knowledge describes their concern and scope of perception in their interaction with the natural environment. These findings have a significant contribution to anyone interested in recognizing local cultural attitudes and behaviors and developing learning materials and references for further research.
This research seeks to look deeper into interrelationships between technology, past, and nostalgia in musical reissue products of Indonesian independent recording labels. This research adopted ...qualitative-descriptive method. Data were extracted from documents which are in the form of reissue releases. This research used Media Archeology and Hauntology perspective in analyzing the data collected, which are in the form of physical reissue releases, photographic, and poster archives. Based on the results of analysis it can be concluded that nostalgia is a technology-mediated condition. Even though reissue releases are laden with past elements, it can be utilized to project future by tracing or identifying various potential creativities contained in past cultural products.
