Bias control in bodywork therapies: a review of methodological issues

OBJECTIVE: To review and summarize the methodological challenges in clinical trials of bodywork or handson mind-body therapies such as Feldenkrais Method, Alexander Technique, Trager Work, Eutony, Body Awareness Therapy, Breath Therapy, and Rolfing, and to discuss ways these challenges can be addressed. DESIGN: Review and commentary. METHODS: Search of databases PubMed and EMBASE and screening of bibliographies. Published clinical studies were included if they used individual hands-on approaches and a focus on body awareness, and were not based on technical devices. RESULTS: Of the 53 studies identified, 20 fulfilled inclusion criteria. No studies blinded subject to the treatment being given, but 5 used an alternative treatment and blinded participants to differential investigator expectations of efficacy. No study used a credible placebo intervention. No studies reported measures of patient expectations. Patient expectations have been measured in studies of other modalities but not of hands-on mind-body therapies. Options are presented for minimizing investigator and therapist bias and bias from differential patient expectations, and for maintaining some control for nonspecific treatment effects. Practical issues with recruitment and attrition resulting from volunteer bias are addressed. CONCLUSIONS: Rigorous clinical trials of hands-on complementary and alternative therapy interventions are scarce, needed, and feasible. Difficulties with blinding, placebo, and recruitment can be systematically addressed by various methods that minimize the respective biases. The methods suggested here may enhance the rigor of further explanatory trials

Gratitude in the Time of the Coronavirus:A Thematic Analysis of the Three Good Things in Young Adults

The COVID-19 pandemic has significantly disrupted the daily lives of college students, resulting in elevated levels of stress, anxiety, and isolation. Research suggests positive psychology interventions aimed at practicing gratitude, offer potential benefits in reducing these common mental health problems. However, there is a limited understanding of how or why these interventions work nor what function gratitude plays in the lives of young adults during the COVID-19 pandemic. As such, the purpose of the paper was to explore the sources and targets of gratitude of college students during the COVID-10 lockdown in Ireland. This study aimed analyse the content of the ‘Three Good Things’ intervention as reported by young adults during the COVID-19 lockdowns in Ireland. A total of 109 college students participated in a 7-day online ‘Three Good Things’ intervention, where they were prompted to reflect on and document three positive experiences each day. Participants were asked to elaborate on how these experiences made them feel and to highlight their role in facilitating these positive experiences. Thematic analysis was used to analyze the 2,200 submitted responses. The findings revealed three overarching themes relating to participants’ expressions of gratitude during the COVID-19 lockdown: (1) cultivating positive social interactions, (2) prioritizing meaningful self-care, and (3) fostering hope for a more normal life post-pandemic. By delving into the lived experiences of college students, this study sheds light on the elements central to their expressions of gratitude during the COVID-19 pandemic. The findings underscore the importance of social connections, self-care practices, and hopeful prospects as sources of gratitude among students.</p

Territory and memory: The Landing of the Allies in Sicily in 1943

The concept of memory (memorial site) has gained crucial importance in recent years for the identification of places (areas) and in the affirmation of local identities. The memorial sites are areas where usually tragic events have occurred and resulted in a cultural change. In these places there are still signs of these historical events and/or tangible and intangible indications created by the society such as: monuments, obelisks, marble inscriptions, others. Sicily represents an ideal area for studying memorial sites; not only because of the number of dominations in the past centuries, but also for the significance of all places where the mafia has taken its root. These elements have caused several changes in the culture and in the landscape. Sicily is the land where \u201cOperation Husky\u201d began, in the summer of 1943. This agreement between the Americans and the British aimed at occupying Sicily, Italy after World War II. Seventy years after this operation the territory is still marked by testimonies of those tragic events. The bombing devastated buildings, which we can still acknowledge for their cultural significance. These memorial areas represent a strong testimony of the past. There are cemeteries, protecting bodies many of which are unknown; there are bunkers and other military garrisons well preserved throughout the territory. These signs must be rediscovered, to be replicated because of the contemporary geopolitical situation. As a result, in this paper we propose to identify the area of eastern Sicily suitable for a tourist itinerary in the cultural memory of the war of 1943. The idea is to encourage tourism that gives rise to real emotions and thoughts

Modeling and control of a modular iron bird

This paper describes the control architecture and the control laws of a new concept of Modular Iron Bird aimed at reproducing flight loads to test mobile aerodynamic control surface actuators for small and medium size aircraft and Unmanned Aerial Vehicles. The iron bird control system must guarantee the actuation of counteracting forces. On one side, a hydraulic actuator simulates the hinge moments acting on the mobile surface due to aerodynamic and inertial effects during flight; on the other side, the actuator to be tested applies an active hinge moment to control the angular position of the same surface. Reference aerodynamic and inertial loads are generated by a flight simulation module to reproduce more realistic conditions arising during operations. The design of the control action is based on a dynamic model of the hydraulic plant used to generate loads. This system is controlled using a Proportional Integral Derivative control algorithm tuned with an optimization algorithm taking into account the closed loop dynamics of the actuator under testing, uncertainties and disturbances in the controlled plant. Numerical simulations are presented to show the effectiveness of the proposed architecture and control laws

Structural changes of in vitro matured buffalo and bovine oocytes following cryopreservation.

The aim of this work was to evaluate chromatin and spindle organization of buffalo and bovine in vitro matured oocytes after vitrification/warming by Cryotop and after their exposure to cryoprotectants (CP). In vitro matured oocytes were vitrified/warmed and exposed to the vitrification/warming solutions containing ethylene glycol (EG), dimethyl sulfoxide (DMSO) and sucrose as CP. Two hours after warming, oocytes were fixed and immunostained for microtubules and nuclei and examined by fluorescence microscopy. Data were analyzed by Chi Square test. A higher percentage of Telophase II stage oocytes was found in the toxicity (26 and 34% in bovine and buffalo) and the vitrification groups (13 and 7% in bovine and buffalo) compared to the control, indicating occurrence of activation. An increased percentage of oocytes with abnormal spindle and chromosome organization was found in oocytes exposed to CP (24 and 13% in bovine; 32 and 30% in buffalo respectively) and in those vitrified (26 and 31% in bovine; 26 and 29% in buffalo respectively) compared to the control (0 in bovine and 2.5 % in buffalo)

Nafion-TiO2 composite DMFC membranes: Physico-chemical properties of the filier versus electrochemical performance

TiO2 nanometric powders were prepared via a sol-gel procedure and calcined at various temperatures to obtain different surface and bulk properties. The calcined powders were used as fillers in composite Nafion membranes for application in high temperature direct methanol fuel cells (DMFCs). The powder physico-chemical properties were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and pH measurements. The observed characteristics were correlated to the DMFC electrochemical behaviour. Analysis of the high temperature conductivity and DMFC performance reveals a significant influence of the surface characteristics of the ceramic oxide, such as oxygen functional groups and surface area, on the membrane electrochemical behaviour. A maximum DMFC power density of 350 mW cm-2 was achieved under oxygen feed at 145°C in a pressurized DMFC (2.5 bar, anode and cathode) equipped with TiO2 nano-particles based composite membranes. © 2004 Elsevier Ltd.

Innovations in Educational Research and Teaching of Experimental Calculus

For several decades, there have been a varying number of books on Calculus following the classic line of mathematical thought, where Mathematics is taught for everybody by means of rigorous definitions, theorems, and carefully detailed and extensive demonstrations. For mathematical education into the XXI Century the students need to achieve ability in handling of present mathematical tools and concepts from the beginning of their courses. These needs can be achieved today by means of a paradigmatic change in the focus of mathematics teaching: to learn to develop ideas and to experiment and test those ideas in such way that students can verify their own inferences. In this paper we report an educational research in teaching and learning functions models according to a new paradigm in hands-on experimental mathematics, with applications in the real world, i.e. sciences and engineering by using Computer Algebra Systems. The study of functions is presented, focused into the framing of Exploratory Learning Systems, where students learn by means of the action and their participation in it. It is designed for teachers working together with students in a computer laboratory like hands-on workshops-type activities on other sciences. In this way students have a more “alive”, “realistic” and “accessible” touch in Calculus
