Exploring Current Practice of Using Technology to Support Collaborative Argumentation in Science Classrooms

The purpose of this qualitative study was to explore how middle school science teachers enact the practice of using technology to support collaborative argumentation in their science classroom. This study employed qualitative case study and drew on data sources of interviews and observations. This study identified two themes. Six teachers regarded scientific argumentation as an important science practice, but five of them integrated this practice into their science class without formally introducing it. All teachers integrated different forms of technology to engage students in scientific argumentation. In this study, the findings suggested there is a need to provide professional development for teachers to learn about scientific argumentation. The findings can be used as a basis for the design and development of professional development training experiences for in-servic

Service Participant Voices in Child Welfare, Children\u27s Mental Health, and Psychotherapy

Service providers are becoming increasingly interested in hearing the views of service participants regarding issues of service delivery. This trend is viewed as progressive and sensitive to the many complex issues facing a diverse service participant population. In order to understand what is known related to this trend, the paper reviews the literature in child welfare, children’s mental health, and psychotherapy where service participant feedback regarding aspects of service delivery has been studied. The findings from the three areas of service delivery are organized into a number of tangible themes. Suggestions for future research in the area of participant voice are noted

Cardiac rehabilitation for heart failure: Do older people want to attend and are they referred?

Purpose Uptake of cardiac rehabilitation services by older people is suboptimal. Offering suitable services may increase participation. This study investigated older heart failure patients' preferences between hospital, community and home-based service models and sociodemographic and clinical factors associated with these preferences. Rates of referral were examined. Methods Cross-sectional survey of patients aged 65 years and older consecutively admitted to elderly care, cardiology and general medicine wards in a large UK hospital with confirmed heart failure between March-December 2009. A 57-item interview schedule incorporating open and closed questions and standard measures was developed enabling both quantitative and qualitative analysis. Associations between patients' preferences and characteristics including disease severity (New York Heart Association [NYHA] classification) and comorbidity (Charlson comorbidity score) were analysed using Chi-squared tests and one-way ANOVA. Results One hundred and six interviews were completed (mean age 77.8 ± 7.3, 62% male, 47% lived alone). Most patients had moderate-severe heart failure (55% NYHA class III; 34% class II) and co-morbidities (mean Charlson score 3.3 ± 1.7). Most opted for cardiac rehabilitation (72%), preferring hospital to community classes. Those preferring hospital programmes were younger (mean 5.1 years, 95% CI -10.1 to -0.1, P = 0.043) than those preferring not to participate. Neither disease severity nor comorbidity was associated with preferences. Only 21% were referred to any cardiac rehabilitation service. Conclusion Most of these older heart failure patients wanted to attend cardiac rehabilitation, but few were referred. Age was related to preferring certain cardiac rehabilitation service models but not to an overall preference to attend. Referral processes need urgent improvement and offering choice of service models may increase participation. © 2014 Elsevier Masson SAS and European Union Geriatric Medicine Society

Soundwalk as a multifaceted practice

The soundwalk was invented as part of the initiatives undertaken by the World Soundscape Project group with an acoustic ecology profile, which emphasised the noise pollution that exists in people’s sonic environment and the need to reacquire our ‘lost skill’ of conscious listening. Initially, the practice of soundwalking was used as a method allowing us to ‘hone our hearing’ (to boost our sonological competence), to show the human condition with respect to modern reality. Soon, the soundwalk became an inspiration for many artistic undertakings that made use of the sonic properties of the environment and employed various listening strategies. This article is designed to present the idea of soundwalking since its theory and practices began to form. By presenting selected works by Hildegard Westerkamp, I intend to show the motivations behind the practice of soundwalking, which encompass the complex issues of perceiving and assessing city sounds. I refer these to Tim Ingold’s proposition to understand sound as a medium of experience. Soundwalking, as a practice of conscious listening by focusing attention on aural sensations, paradoxically seems to reveal the multi‑sensory structure of our relationship with the world, and the mediatory function of sound in our experience of being‑in‑the‑world

Design and implementation of sensor systems for control of a closed-loop life support system

The sensing and controlling needs for a Closed-Loop Life Support System (CLLSS) were investigated. The sensing needs were identified in five particular areas and the requirements were defined for workable sensors. The specific areas of interest were atmosphere and temperature, nutrient delivery, plant health, plant propagation and support, and solids processing. The investigation of atmosphere and temperature control focused on the temperature distribution within the growth chamber as well as the possibility for sensing other parameters such as gas concentration, pressure, and humidity. The sensing needs were studied for monitoring the solution level in a porous membrane material along with the requirements for measuring the mass flow rate in the delivery system. The causes and symptoms of plant disease were examined and the various techniques for sensing these health indicators were explored. The study of sensing needs for plant propagation and support focused on monitoring seed viability and measuring seed moisture content as well as defining the requirements for drying and storing the seeds. The areas of harvesting, food processing, and resource recycling, were covered with a main focus on the sensing possibilities for regulating the recycling process

The Hypermasculine and Ubersexual Men in the Harlequin Novels of the 1980s and 2000s

Harlequin novels are so popular that Harlequin romance emerges as a genre. Unlike on the heroines, there are scarcely any studies or works on the heroes, thus, I want to focus my study on the heroes of Harlequin Romance. By analyzing using the Male Sex Role in the 1980s and themes of masculinity in the 2000s, I will prove that there are four types of ideal men in the 1980s Harlequin novels whose characteristics originated from the ideal men in the society at that time, the Hypermasculine men with extreme masculinity and avoidance of any feminine sides. I will also prove that there are three types of ideal men in the 2000s Harlequin novels whose characteristics are in accordance with the Ubersexual men\u27s, the ideal men in the society in 2000s having positive characteristics of traditional manliness with some “feminine“ characteristics. The reason behind these changes is because of the changes in the heroines and the characteristics of men in the society in time and these push for the changes in the heroes. As a publisher, Harlequin\u27s goal is the highest selling rate, thus, they adjust to the market\u27s demand
