A Proposed Exploratory Study of Object Detectors to Learn the Influence of Datasets on Model Performance

The quality of the images used to train the models in the field of object detection using deep learning models is critical in determining the model’s quality. However, there are very few methods for exploring these images in datasets to see what aspects in these images have a significant impact on the model’s performance. This could be one of the reasons why the models don’t match human perceptions. There is a need for more study that can suggest unique methodologies to address the topic at hand because the existing literature overlooks this line of thought. As a result, this paper provides a methodology based on exploratory sequential design, which may be used to identify several aspects of images in the dataset that influence model performance.

CRITERIA FOR THE DEFINITION OF INDICATORS IN ARCHITECTURAL LEARNING IN THE DESIGN STUDIO THROUGH THE USE OF THE E-PORTFOLIO

The objective of this research is to identify, within the context of teaching-learning through the Design Studio, factors and criteria which may support the construction of architectural indicators of learning in students. This may be achieved through the integrated analysis of the evidences of learning included in the e-portfolio, using the traditional learning process as a complement in the Design Studio. This research is of mixed type and includes an exploratory sequential design of longitudinal type that ran through a period of six consecutive semesters. The results obtained show the full potential of objectual and collaborative evidences contained in the e-portfolio, in order to reflect the presence of architectural learning elements, as well as the presence of factors and features specific to the context and dynamics of the learningteaching process, which may result in an approach to the construction of potential architectural indicators of learning.

Using the Exploratory Sequential Design for Complex Intervention Development: Example of the Development of a Self-Management Program for Spinal Cord Injury

In the exploratory sequential design, the qualitative phase occurs first and is followed by the quantitative phase. The methodological purpose of this article is to demonstrate how an exploratory sequential approach, including the use of a joint display, can be used for complex intervention development. This article presents and integrates the qualitative and quantitative findings from a series of previously published studies on the considerations for a tailored self-management program for individuals with spinal cord injury. This article serves as a reference for other researchers, clinicians, and/or other stakeholders on using the exploratory sequential design for complex intervention development. The exploratory sequential design should be used more broadly for the development of relevant and sustainable interventions.

Efektifitas Model Pembelajaran Problem Base Learning Berbantukan Multimedia Terhadap Kemampuan Pemecahan Masalah Siswa

[Effectiveness Of Using Multimedia with Problem Base Learning Models to Increase Students Problem Solving Skill]. Penelitian ini bertujuan untuk memperoleh informasi tentang efektifitas pembelajaran. Metode penelitian yang digunakan adalah penelitian campuran jenis Exploratory Sequential Design. Penelitian ini akan mendapatkan data kualitatif dan kuantitatif yang keduanya akan digabung untuk memperoleh data yang lebih rinci dan saling menguatkan. Berdasarkan hasil temuan pada penelitian ini didapatkan bahwa: (1) Kemampuan pemecahan masalah pada kelas PBL berbantuan multimedia lebih tinggi dibandingkan dengan kelas PBL. (2) Multimedia berpengaruh terhadap kemampuan pemecahan masalah siswa dengan nilai uji -t = 0.007. (3) Ketuntasan siswa pada kelas PBL berbantukan multimedia mencapai 88% sedangkan pada kelas PBL mencapai 50%. Dengan demikian dapat disimpulkan bahwa penerapan model PBL berbantuan multimedia efektif meningkatkan kemampuan pemecahan masalah siswa.

Caracterización de competencias docentes específicas en el área de ciencias exactas / Characterization of Specific Teaching Competences in the Area of Exact Sciences

ABSTRACTThe study consisted in identifying specific teaching competences pertinent to the programs taught by the Facultad de Ciencias (FC) of the Universidad Autónoma de Baja California (UABC). The study had an exploratory sequential design; for the qualitative phase, the content analysis technique was implemented, from which five specific teaching competences are characterized. For the quantitative phase, the questionnaire “Specific teaching competences” was designed and applied. The results lead to confirmation of the relevance of having relevant competencies to the programs where the teaching function is exercised; when participating professors are identified as competent in promoting research and dissemination of science.RESUMENEl objetivo de este estudio consistió en identificar competencias docentes específicas pertinentes a los programas educativos que se imparten en la Facultad de Ciencias (FC) de la Universidad Autónoma de Baja California (UABC). El estudio es de tipo exploratorio, sigue un diseño exploratorio secuencial; para la fase cualitativa se implementó la técnica de análisis de contenido en los programas educativos, a partir del cual se caracterizaron cinco competencias docentes específicas. Posteriormente, se diseñó el cuestionario “Competencias docentes específicas”, que en la fase cuantitativa se aplicó a 13 profesores de Tronco Común de Ciencias Naturales y Exactas de dicha Facultad. Los resultados llevan a la confirmación de la relevancia que adquiere el contar con competencias pertinentes al programa educativo en el que se ejerce la función docente; al identificarse en los profesores participantes, competencia en fomentar el pensamiento crítico, investigación y difusión de la ciencia, pero una menor capacidad para generar ambientes de innovación y uso de herramientas de cómputo científicas.

En los centros educativos de naturaleza cooperativa es preciso disponer de auténticos líderes que dinamicen a todos los agentes con la finalidad de conseguir un progreso en la entidad educativa que conforman. Este estudio se centra en conocer el fenómeno del liderazgo docente en los centros educativos de naturaleza cooperativa. Para ello, se ha seguido un método cuantitativo de análisis de datos recogidos previamente por medio de un cuestionario aplicado a una muestra de 250 docentes de cooperativas de enseñanza de España.

Employees' perspective of characteristics of small business leadership : a mixed methods study

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study explored characteristics of small independent restaurant business leaders using an exploratory sequential design of mixed methods research through employees' perspectives. The findings from the qualitative study (phase 1) were later used to develop a leadership measure for small independent restaurants and test it quantitatively (phase 2) for generalization. An exploratory sequential design in which qualitative research was conducted first was employed because of (a) the unique operations of small independent restaurant businesses that affect their owners' management style and (b) the lack of leadership studies on small hospitality businesses. In addition, no measure of leadership approach specifically for small independent restaurant businesses is found in the literature. Furthermore, most leadership constructs have been developed by using leaders or managers of businesses outside the hospitality industry and neglected employees' perceptions. Qualitative data were collected through three focus groups and one dyadic interview with 11 participants. The results of the qualitative data analysis revealed nine themes (respectful, compassionate, communication, experienced, delegation, recognition, sociable, emotional control, organized). A construct was developed using Hinkin, Tracey, and Enz's (1997) guidelines for scale development and analysis specific to the hospitality industry field research setting. For phase 2, the developed questionnaires were distributed via Amazon Mechanical Turk with a survey link created by University of Missouri Qualtric Survey Software. A total of 457 data items were collected and 366 were used for analysis. The quantitative results showed that the leadership characteristics of respectful, recognized, organized, and experienced were significantly related to employee intention to leave. In addition, leader-member exchange did not play a mediating role in the relationship between characteristics of small restaurant leadership and employee intention to leave, while employee work engagement only had a mediating role on two factors in the relationship between two characteristics (respectful and organized) of small restaurant leadership and employee intention to leave.
