Integrating Public Art,Environmental Sustainability,and Education: Australia's ‘Creative Village’ Model

This paper will attempt to position the Creative Village project within the parameters of an international debate on public art, sustainability and education. It will begin with a brief history of the project and its community and arts origins, then examine its engagement with environmentally-responsive art and design, and finally its integrative educational paradigm. I will argue that the value and significance of the programme is that it has successfully bridged complex educational, design, community and environmental goals through having clear core values and a practice of flexible delivery.     

“When I Grow up I Would Like to Be …”: Factors Affecting Career Choice of Community Disability Workers in Southern Africa

The effectiveness of community based rehabilitation (CBR) programmes depends on the calibre of staff recruited and employed. Therefore, this study aimed to understand how the life experiences of community disability workers (CDWs) in Malawi, Botswana and South Africa influenced their choice of career. A life history approach was used to gather data from 16 CDWs, involving two interviews of each participant. Disability Studies postgraduate students conducted the interviews and analysed the data with academic staff, using thematic content analysis. It was found that lack of career guidance and information about community disability work affected participants’ initial choice of career. Some ended up in CBR because poor schooling prevented them from choosing other careers. Personal experience of disability and exposure to role models in rehabilitation motivated the career choice of some. The authors make recommendations including the selection of trainees with personal experience of disability and CDWs mentoring potential recruits.     

A philosophical and evolutionary approach to cyber-bullying: social networks and the disruption of sub-moralities

Cyber-bullying, and other issues related to violence being committed online in prosocial environments, are beginning to constitute an emergency worldwide. Institutions are particularly sensitive to the problem especially as far as teenagers are concerned inasmuch as, in cases of inter-teen episodes, the deterrent power of ordinary justice (i.e. threaten to sue) is not as effective as it is between adults. In order to develop the most suitable policies, institution should not be satisfied with statistics and sociological perspectives on the phenomenon, but rather seek a deep ethical understanding—also referring to the biological and evolutionary past of human beings. The aim of this paper is to show a way to fill this theoretical gap, offering some answers (and some questions too) that can illuminate future policy-oriented research and reflection. In order to do so, we will start by connecting our argument to evolutionary studies carried out in the past two decades, focusing on gossip as a tool for social assortment, thus endowed with a dual function: protect the group from free riders, intruders and bullies but also bully the deviant members. In the “Mediating gossip through social networks” section, we will see which aspects of gossip, vital for bullying, are co-opted by social network scenarios. A fundamental trait of human social life, that is the subdivision in smaller coalitions, or sub-groups, will be shown as missing in social networks (SN) dynamics—therefore constituting themselves as structurally violent. The “Why and how do social networks empower bullying?” section will deal with techno-ethical and epistemological concerns regarding how gossip, mediated by SN, manages to empower cyber-bullying. The “Self-gossip and self-mobbing in the light of the disruption of sub-moralities” section will characterize cyber-bullying as often sparked by self-gossip (soon degrading into self-mobbing) in a scenario where familiar sub-groups, which also mediate defense and mutual understanding, are disrupted. The “Discussion and conclusion” section will consist of a philosophical summary, divided in two parts: a pars destruens analyzing whether SN, in their actual configurations, are fit for being used by humans-like-us, and a pars construens examining the broad potential consequences of highly enforced regulation aimed at contrasting cyber-bullying.     

Improving the design of squat machine using motion capture and virtual prototyping

Dynamic squat is one of the most executed fitness exercise. Its use is widespread both for rehabilitation and training purposes. Several typologies of the squat exercise can be performed. The most important are the front squat and the back squat. In the front squat the barbell is held in front of the body across the clavicles and deltoids, while in the back squat exercise the bar is held on the back of the body at the base of the neck. In this paper we will refer to dynamic back squat. The squat exercise can be performed with or without the help of a machine that has the scope of guiding the person during the movement and ensuring his stability and safety. The use of this type of machine is often necessary when the workout is heavy and the risk of incorrect exercise and injuries is high. On the other hand, the rigid structure of this device often overconstrains the lifting movement. From all these observations, the purpose of the paper is to discuss an alternative design of a mechanism able to maintain the advantage to allow a free-body execution and to preserve the safety of the athletes as well. The proposed mechanism has been designed starting from an anthropometric study on the squat movement. This has been performed by using a motion capture system and applying computer-aided engineering techniques. The design activity started from the experimental investigation of the trajectory of the barbell during the natural execution of the unrestricted back squat exercise. The tests have been performed on several subjects with different mass, anthropometry and gender. In a second phase, the data have been processed and analyzed and a specific mechanism, able to reproduce the natural trajectories, has been synthetized. Finally, the design and optimization of the entire structure has been performed through the use of virtual prototyping techniques.     

Applying the technology acceptance model to a Spanish City Hall

This paper examines the relative importance and significance of the four technology enablers introduced by Davis (1989) in the technology acceptance model (TAM) (perceived ease of use, perceived usefulness, attitude towards using and behavioural intention) for use on four different levels of citizen engagement in e-government (null, publish, interact and transact). An extended technology acceptance model (TAM) is developed to test citizen engagement towards online e-government services from a sample of 307 citizens who used the benefits advisor tool within a Spanish City Hall. Although the proposed model follows TAM and explains the intention towards the actual use of e-government by postulating four direct determinants, “A, PU, PEOU and BI” have been considered as parallel processes, meaning that each can have separate influence in different levels of citizen engagement. To achieve this goal, a multinomial logistic regression is developed and tested to confirm the explanatory power of the four technology enablers on the four different levels of e-government. Our findings further suggest that in order to implement e-government, some of the enablers matter more than others to move from one level of citizen engagement to another. The main contribution of the paper is to question the use of existing models which seek to represent the relationship between technology enablers and the adoption of e-government services without considering their impacts on citizens’ engagement. The implications of the findings are discussed and useful insights are provided in relation to policy recommendations geared to create appropriate conditions to build citizens’ engagement intent of use of e-government services.     

STEM Integration in Middle School Life Science: Student Learning and Attitudes

In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning.     

Internal and External Time Conflicts in Adolescents: Sleep Characteristics and Interventions

ABSTRACT— Daytime fatigue and lack of sleep seem to increase throughout adolescent years. Several environmental, psychological, and biological factors have been associated with the development of sleep across adolescence. The aim of the present article is to summarize these factors and to give examples of various outcomes in sleep patterns among adolescents studied in different cultural settings. It is obvious from earlier work that many adolescents have displaced circadian rhythms and lack of adaptation to school hours due to an early school start or additional burdens for work. Several interventions have aimed to help the adaptation process by supporting sleep processes and changing scheduling, in this way promoting classroom alertness. In summary, adolescents worldwide shorten their sleep due to schoolwork hours and additional work, especially by disturbing their sleep due to circadian misalignment.     

Hanging tough: post-PhD researchers dealing with career uncertainty

ABSTRACT

This study examines the impact of career uncertainty on post-PhD researchers’ experiences. Drawing on an identity-trajectory approach and a qualitative design, we analysed experiences of post-PhDs from the UK and Switzerland. Our findings show that in the course of their work experiences, career uncertainty takes two different forms: intellectual uncertainty and occupational uncertainty. On a daily basis, both forms strongly impact the participants’ work and personal lives and can limit their ability to plan for the future, restrict their developing research expertise and networks and induce tension in trying to reconcile work and personal lives. While often struggling with a blurred institutional status, participants ‘hang tough’ despite their uncertain situation, notably by clinging to the academic researcher identity. Contributing to the previous work on the increasing casualisation of post-PhD positions and the resulting challenges, our study offers new insights into how different aspects of career uncertainty influence post-PhDs’ work and identity.     

The Function of Executive Function: Everyday Manifestations of Regulated Thinking in Preschool Settings

Executive function (EF) encompasses higher-order mental processes necessary for the conscious control of thought and action in the service of goals. Once thought not to apply to children at all, EF is now at the center of a burgeoning body of research on young children over the last 10–15 years indicating that it is a critical foundation of school readiness and performance. Despite the widely agreed relevance of EF to the transition to formal learning, findings have not yet been applied to preschool classrooms in any widespread way. Part of the reason for this is that despite general agreement on the broad definition of EF, the subdomains EF comprises—especially in early life while it is emerging—are still a matter of debate. It is therefore a challenge to bring the relevant concepts down to an even further level of granularity, i.e., specific behaviors ecologically grounded in everyday preschool interactions. We took the initial steps of this challenge by curating EF-related behaviors from the extant literature, expert and master teacher interviews, and observations in high-quality preschool classrooms into a new protocol called Preschool-Setting Executive Function. This observational system includes child behaviors as well as teacher support behaviors that encourage children’s organized, higher-order thinking. We then employed the final protocol in an additional set of classrooms to provide an initial assessment of its usefulness in identifying “EF in context.” Results indicate (1) EF and EF-support behaviors are low-frequency occurring, (2) children are more engaged in organized thinking than teachers are in the support of it, (3) teachers’ presence, especially if they are expanding play, promotes children’s real-time EF-behaviors. Results are discussed in terms of how this system may be used as a basis for future professional development to enhance teacher practice around the promotion of EF.
