REDUCING SELF-INJURY AND CORRESPONDING SELF-RESTRAINT THROUGH THE STRATEGIC USE OF PROTECTIVE CLOTHING

We examined the use of protective clothing to reduce a retarded male's face-punching and leg-kicking and two corresponding forms of self-restraint—arm and leg self-restraint. The resident was observed each day in three sessions of randomly ordered conditions (one condition per session): without any protective clothing, with a padded helmet, and with a padded helmet and padded slippers. Use of the padded helmet substantially reduced face-punching and arm self-restraint. The addition of padded slippers reduced leg-kicking and leg self-restraint. These results suggest a practical and effective means of controlling self-injury and self-restraint. They are also consistent with the possibility that the resident's arm restraint was maintained in part by escape or avoidance of face-punching and that his leg restraint was maintained in part by escape or avoidance of leg-kicking.     

Systematic application and removal of protective equipment in the assessment of multiple topographies of self-injury

We evaluated the effects of systematic application and removal of protective equipment on three topographies of self-injurious behavior (SIB) exhibited by a girl who had been diagnosed with autism. Results showed that when protective equipment was applied, SIB decreased to near-zero levels. In addition, withdrawal of protective equipment for specific topographies of SIB (by removing only the corresponding padding) increased rates of SIB only for that topography of SIB. Next, a functional analysis of hand SIB showed that protective equipment suppressed this behavior in all conditions and that the behavior was maintained by automatic reinforcement when padding was removed. Results are discussed in terms of sensory extinction as a possible mechanism responsible for response suppression.     

On the relation between object manipulation and stereotypic self-injurious behavior

Results from a number of studies have shown an inverse relationship between stereotypic behavior and object manipulation. The purposes of this study were to determine whether techniques similar to those used previously (prompting and reinforcement) would be effective in increasing object manipulation under both prompted and unprompted conditions, and to ascertain whether increases in object manipulation would result in decreases in stereotypic self-injurious behavior (SIB). Two individuals with developmental disabilities who engaged in SIB maintained by automatic reinforcement participated. Results showed that object manipulation increased from baseline levels when experimenters prompted participants to manipulate leisure items, but that object manipulation was not maintained under unprompted conditions, and rates of SIB stayed within baseline levels. We then attempted to increase object manipulation further by (a) reinforcing object manipulation, (b) blocking SIB while reinforcing manipulation, and (c) preventing SIB by applying protective equipment while reinforcing object manipulation. Reinforcing object manipulation alone did not affect levels of object manipulation. Blocking effectively reduced attempts to engage in SIB for 1 participant but produced no increase in object manipulation. When the 2nd participant was prevented from engaging in SIB through the use of protective equipment, rates of object manipulation increased dramatically but were not maintained when the equipment was removed. These results suggest that stimulation derived from object manipulation, even when supplemented with arbitrary reinforcement, may not compete with stimulation produced by stereotypic SIB; therefore, direct interventions to reduce SIB are required.     

Controlling the flight on double-handed foiling catamarans: The role of shared equipment on the crew members' mutual modes of regulation

The purpose of this study was to contribute to the understanding of the role of shared sport equipment in the collective coordination of a team. It was conducted within an enactive approach of human cognition by mobilizing the methodological tools and methods of the Course of Action framework. Six crew members of hydrofoil sailing catamarans participated in this study. Data collection consisted in video-recording training sessions followed by individual self-confrontation interviews. A qualitative analysis of the data allowed typical modes of regulation of the flight to be characterized from each crew member's perspective. Three main modes of regulation were identified. All of them involved either salient perception of the boat's movements, or actions directed to regulating the boat’s movement. In the discussion, we propose a distinction between three types of collective sport situations, regarding the role of the material environment of athletes in their coordination. This distinction opens new perspectives both for future research on team coordination, and for pedagogical and training implications.     

Guidelines to Integrate Spirituality and Spiritual Care in Occupational Therapy Education: A Modified Delphi Study

This modified Delphi study aimed to develop educational guidelines for integrating spirituality and spiritual care into occupational therapy education. The first round comprised a self-administered questionnaire, the second round used a face-to-face workshop, and last round reviewed the developed educational guidelines, which reached the highest agreement and median values greater than 3.25. A panel of 18 comprised occupational therapy educators, clinicians, and nursing experts were recruited. A total of 126 out of 142 items reached the highest agreements from the panel participants, categorized based on the content knowledge-based, importance, skills, ethics, pedagogical approaches, teaching and learning strategies, and assessment of student learning.     

General analytical solution for stress intensity factor of a hypocycloid hole with many cusps in an infinite plate

In this article, the problem for the determination of the displacement functions and the stress intensity factors (SIFs) around a boundary of a hypocycloid hole with cusps in an infinite elastic plate subject to normal and shear stresses are presented. A hole with cusps (hypocycloid) is mapped onto a unit circle and the modified complex potential is used for solving the relevant boundary value problems. An analytical solution for the SIF of a hypocycloid hole is obtained. For a special case, our results agree with others.     

Behavioral strategies for reducing disease transmission in the workplace

The coronavirus pandemic highlighted that workplaces may serve as a hub of disease transmission if proper precautions are not enacted. The Centers for Disease Control recommends several strategies for decreasing the spread of illnesses in the workplace, including a) promoting proper hand hygiene, b) cleaning and sanitizing the work area, c) encouraging sick employees to stay home, d) personal protective equipment, and, e) social distancing. Research suggests that instructions are often not sufficient to change work behaviors, and behavioral interventions may be needed. Thus, the present paper reviews existing research that informs the implementation of behavioral strategies to reduce the spread of disease in the workplace, and makes recommendations for organizations to protect employees, clients, and customers. Intervention components such as training, prompts, the reduction of response effort, clear workplace policies, feedback, and consequences are discussed, and practical recommendations and suggestions for future research are provided.     

BIOMEDICAL ETHICS: MUSLIM PERSPECTIVES ON GENETIC MODIFICATION

Technology pertaining to genetically modified foods has created an abundance of food and various methods to protect new products and enhance productivity. However, many scientists, economists, and humanitarians have been critical of the application of these discoveries. They are apprehensive about a profit‐driven mentality that, to them, seems to propel the innovators rather than a poverty‐elimination mentality that should be behind such innovations. The objectives should be to afford the most benefit to those in need and to prevent hunger around the world. Another major concern is the safety of genetically modified food. Muslims, as well as those in other religious communities, have been reactive rather than proactive. Muslims must connect scientific knowledge and ethical behavior based on faith. In Islam, there is no divide between the two. God has commanded us to seek knowledge and make discoveries to better our lives and our environment. We are trustees of this world and everything in it. The poor, the sick, and the wayfarers have a right to be fed and cared for. God reminds Muslims continuously that the earth and all the heavens belong to God; therefore, no one should feel hunger, no one should suffer or be prevented from sharing this bounty.     

An empirical comparison of three variants of the AHP and two variants of conjoint analysis

This paper provides an empirical comparison of two methods of attribute valuation: the analytic hierarchy process (AHP) and conjoint analysis. Variants within each approach are also examined. The results of two empirical studies indicate that the methods differ in their predictive and convergent validity. Within the AHP methods no significant difference in predictive validity was found. Within the conjoint methods, the ranking method significantly outperformed the rating method. The difference in predictive validity between the AHP and conjoint methods was significant in the second study but not in the first study, suggesting superior performance of the AHP over conjoint analysis in complex problems.

Increasing meal consumption in individuals with competing protective equipment

Individuals diagnosed with autism spectrum disorder may engage in self‐injurious behavior that can cause tissue damage. Protective equipment is sometimes used to decrease the severity of tissue damage when self‐injury occurs. However, wearing protective equipment may be incompatible with some forms of adaptive behavior, such as meal consumption. The purpose of the present analysis was to identify a treatment for increasing meal consumption in two adolescent males diagnosed with an autism spectrum disorder who wore protective equipment that interfered with self‐feeding. Three interventions were evaluated: modifying the protective equipment, manipulating the reinforcing efficacy of the meal, and arranging additional positive reinforcement for meal consumption in the absence of protective equipment. Modifying protective equipment and manipulating the reinforcing efficacy of the meal were effective for both participants. Additional positive reinforcement was evaluated and effective for one participant.
