Optimized cuttlefish algorithm for diagnosis of Parkinson’s disease

This paper presents an optimized cuttlefish algorithm for feature selection based on the traditional cuttlefish algorithm, which can be used for diagnosis of Parkinson’s disease at its early stage. Parkinson is a central nervous system disorder, caused due to the loss of brain cells. Parkinson's disease is incurable and could eventually lead to death but medications can help to control symptoms and elongate the patient's life to some extent. The proposed model uses the traditional cuttlefish algorithm as a search strategy to ascertain the optimal subset of features. The decision tree and k-nearest neighbor classifier as a judgment on the selected features. The Parkinson speech with multiple types of sound recordings and Parkinson Handwriting sample’s datasets are used to evaluate the proposed model. The proposed algorithm can be used in predicting the Parkinson’s disease with an accuracy of approximately 94% and help individual to have proper treatment at early stage. The experimental result reveals that the proposed bio-inspired algorithm finds an optimal subset of features, maximizing the accuracy, minimizing number of features selected and is more stable.     

Grit and academic performance among first-year university students: A brief report

This study examined grit and academic performance among a sample of South African university students (n = 121, mean age = 19.55, SD = 1.77, female = 57.85%). Data were collected using the Grit Scale and academic performance was assessed over one academic semester. Simple regression analysis was computed to predict students’ academic achievement from components of their self-reported grit. The grit component of consistency of interest accounted for 3% of the variance in the student’s academic achievement scores. Similarly, the grit component of perseverance of effort explained 9% of the variance in scores. Students who scored high on the Grit Scale also obtained higher academic marks compared to participants who scored low on the same instrument. The findings suggest that grit is an important personal resource for higher education students.     

‘Inhliziyo ekhombisa uthando’: Exploring children’s conceptions of spirituality

In this study we explored young isiZulu children’s conceptions of spirituality. The children (n = 8; females = 5; male = 3) were nine to eleven years old and attended a primary school in KwaZulu-Natal, South Africa. They drew pictures depicting their sense of spirituality and answered questions on vignettes or scenarios that contained a moral dilemma. The children also engaged in conversations with a picture, and wrote a letter to God. Thematic analysis of the data yielded three themes that characterised the children’s emerging conceptions of their spirituality: conceptions of a transcendental being; spirituality as a search for personal meanings; and influences on emerging conceptions of spirituality. For the young children, being spiritual was about connecting with a transcendental being and with significant others in their lives through expressions of love, respect, hope, faith, compassion, closeness, fairness, and empathy. Children appear to acquire a sense of spirituality mainly by internalising experiential interactions within their social and material environment.     

Mentoring in-service chemistry teachers: acquirements as mentees

The aim of this study is to identify a group of chemistry teachers’ (mentees) acquirements of mentoring program by analyzing their reflective journals. Four mentees participated in this study and they met with their mentors once a week for eight consecutive weeks. The mentees devised lesson plans as well as activities during the mentoring sessions. After each mentoring session, the mentees were asked to reflect the process and their gains to their journals. The journals were analyzed in two stages; content analysis of the journals and the analysis of the mentees level of reflections. The analysis of the mentees’ journals showed that the mentorship program supported the mentees to improve their pedagogical content knowledge; allow them to utilize various methods, techniques, and materials in their lessons. Besides, the mentees indicated that they performed chemistry courses more effectively with the help of the acquirements from the mentoring sessions. The result of this study showed also that mentors can play key roles in supporting professional developments of teachers. It is suggested that rehearsing lesson plans before going into the classroom would make the mentoring sessions more beneficial.     

Empowering students through peer assessment: interrogating complexities and challenges

This paper describes a self-study of the author’s implementation of peer assessment (PA) in an undergraduate education course. The goal was to improve alignment of assessment practice and theory of practice, by introducing PA to empower students and draw on their funds of knowledge. The PA design is described, and student perception data are analysed alongside lecturer reflections. The focus is on elaboration of personal learning points for the author. Findings suggest the success of PA related to students’ ideas about its value, highlighting the importance of motivation to engage as peer assessors. Other findings revealed the author’s blindspots, because there were ways that her values and beliefs constrained goal attainment, and illuminated next steps.     

Reflecting on a journey of resilience in children’s blood and cancer nursing

Reflective practice is recognised as an integral part of being a highly skilled and successful health care professional. Many benefits have been identified from being a reflective practitioner including the opportunity for critical thinking, growing self-awareness and supporting individual resilience. There is a growing body of literature recognising the negative emotional impact that caring for children with cancer and blood disorders can have on health professionals. Currently there is an emerging interest in a more strengths-based approach focused on maintaining staff wellbeing. Resilience has been suggested as a framework for coping and maintaining wellbeing in areas, like children’s oncology and has been used as a term to describe the ‘surviving’ health professional. This paper explores the first author’s (GA) experiences of being a children’s oncology nurse and paediatric palliative care nurse specialist in the context of existing empirical and theoretical literature, with a particular focus on how GA developed resilience. Reflective examples of practice are used within the context of themes identified from a recent literature review exploring how resilience is defined within empirical literature.     

The Science and Art of Integrating Psychodrama and Bernard’s Discrimination Model

This article presents the useful technique of Jacob L. Moreno’s psychodrama in counselor education supervision training. This article addresses how psychodrama can be used with student supervisors who are not sure which of Bernard’s discrimination model roles they are using in supervision. Bernard’s model uses three roles that help supervisors function successfully in their relationships with supervisees. Psychodrama may help student supervisors decide what action would be the most appropriate in a given supervision session. Student supervisors may also benefit from psychodrama in processing internal conflict they may experience in their supervisory role. Faculty members training new supervisors may use these techniques to help their student supervisors gain more awareness on how they view their relationships with supervisees.     

金钱刺激和决策者角色对个体道德决策的影响——基于过程分离范式

以大学生为被试,采用3（金钱刺激：无金钱刺激、金钱奖励、金钱惩罚）×2（决策者角色：决策者、旁观者）的被试间实验设计,利用过程分离范式分别计算被试道德决策中的功利主义倾向和道义论倾向,从而探讨金钱刺激和决策者角色对个体道德决策的影响。结果发现：（1）无论是决策者还是旁观者,金钱刺激都不会影响其道义论倾向;（2）决策者的道义论倾向大于旁观者;（3）只在有金钱奖励时决策者的功利主义倾向才大于旁观者。     

Indigenous Women’s Ways of Knowing and Healing in Mexico

ABSTRACT

This article focuses on examples of Indigenous ways of knowing in three communities of northern and southern Mexico. It centers on dialogue conducted with Indigenous women from Northern Baja California (Arcelia, the cultural healer from the Kumiai community of San Jose de la Zorra), Oaxaca (Maria Sabina through textual analysis of the only book that houses her healing wisdom), and Chiapas (the Lacandon community of Lacanja Chansayab). It then highlights ways in which the author—an academic woman—brought the wisdom of Indigenous cultures to the center of academic discourse, and how Indigenous women apply their knowledge and wisdom to heal their communities. Lastly, the article concludes with lessons learned from the dialogues with Indigenous women, how they have applied innovative research and healing strategies that depart from Euro-American paradigms, and how they creatively contribute to the development of Indigenous psychologies that are anchored in feminist, popular power.
