Introduction: Little is known about the effects of specific behavioral strategies to reduce stereotypy and self-injury for learners with sensory impairments and additional disabilities. Method: A single-subject, multi-treatment withdrawal design was used to test the isolated and combined effects of physical prompting to engage in object manipulation of preferred items, contingent reinforcement, and response blocking on target hand-related stereotypy and object manipulation for one 9-year-old boy with deafblindness and additional disabilities. Results: A functional relation was observed to show that hand-related stereotypy decreased due to prompting and reinforcement of object manipulation. Adding response blocking had inconsistent positive effects on stereotypy, and a functional relation was not observed. Prompting alone did not appear to increase object manipulation until contingent reinforcement was added, and response blocking did not appear to have an additive effect to increase object manipulation. Discussion: Results contradict findings of the replicated study and indicate need for further research, including research carried out in natural environments. Implications for Practitioners: Practitioners can use this research to justify the application of differential reinforcement of incompatible behavior using functional activities that result in meaningful reinforcement for students.

Although speech–language pathologists increasingly make use of tablets in clinical practice, little research to date has evaluated the effectiveness or efficiency of tablet use for targeting speech sound goals. The twofold purpose of this study was to compare (a) the effectiveness and (b) the efficiency of speech sound intervention using tablets versus flashcards. Four kindergarten students with at least two similar speech sound errors participated in this adapted alternating treatments single subject design study that explored the functional relation between speech sound intervention that differed by modality of delivery (tablet vs. flashcards) and increased speech sound skill in elementary school children with speech sound errors. Flashcards and tablets were both effective single-word speech sound intervention modalities; however, for three of the four participants, flashcards were more efficient than tablets.

Given the drastic changes in our lifestyles and ecosystems worldwide, the potential health effects of natural environments have grown into a highly pervasive topic. Recent scientific findings suggest beneficial effects from nature exposure on human immune responses. This review aims at providing a comprehensive overview of literature published on immunomodulatory effects of nature exposure by inhalation of natural substances. A systematic database search was performed in SCOPUS and PubMed. The quality and potential bias of included studies (n = 33) were assessed by applying the EPHPP (Effective Public Health Practice Project) tool for human studies and the ARRIVE (Animal Research: Reporting of In Vivo Experiments) and SYRCLE (Systematic Review Centre for Laboratory Animal Experimentation) tools for animal studies. The synthesis of reviewed studies points to positive effects of nature exposure on immunological health parameters; such as anti-inflammatory, anti-allergic, anti-asthmatic effects or increased NK (natural killer) cell activity. Decreased expression of pro-inflammatory molecules, infiltration of leukocytes and release of cytotoxic mediators are outcomes that may serve as a baseline for further studies. However, partially weak study designs evoked uncertainties about outcome reproducibility and key questions remain open concerning effect sizes, duration of exposure and contributions of specific vegetation or ecosystem types.

AbstractIntroduction: Although this paper deals mostly with the positive effects of a posthumanist worldview on environmental sustainability, partnership, or moral accountability in science and scientific research, it also promotes a new understanding of our educational practice in higher education. The ideas espoused have the ability to inspire educators at all levels to show students, future researchers or other professions about the importance of a progressive, holistic approach to our environment. We claim that being sensitive and caring for our environment is not only part of our moral and ethical responsibility, it is an inseparable aspect of our environmental education, our environmental intelligence. This paper discusses posthumanist1 reciprocity ethics in the context of traditional knowledge (TK) and the protection of indigenous traditional knowledge from commercial exploitation.Methods: Instances of unethical bioprospecting and biopiracy were common throughout the turn of the 21st century and are discussed using cases in countries such as Cameroon, India, South Africa and Australia, where medicinal plant species were, are still a highly sought-after source of potent, pharmacologically active phytochemicals.Results and discussion: The observed increase in regulations against bioprospecting on indigenous land in these countries as a result of intellectual property monopoly by big pharmaceutical companies is discussed in this paper along the lines of a ‘humanist vs posthumanist’ ontology. Patent exclusivity laws have historically marginalized the proprietary owners of indigenous traditional knowledge, creating a moral and ethical rift between those that seek to exploit this knowledge commercially and those from whom the knowledge originally comes from. This disconnection from nature and natural resources due to a humanistic approach2 to growth and development, often leads to environmental exploitation, exploitation of indigenous people and unsustainable commercial practices. Existing research and bioprospecting ethics that are practiced on indigenous lands must be questioned in their ability to provide mutually beneficial outcomes for all stakeholders.Conclusions: The posthumanist approach to morality and research ethics is discussed in this paper as a possible and practical alternative to humanism along with the potential for posthumanist ethics to be a tool to shape legal frameworks and the policies that protect at-risk communities and their respective natural environments. Our current developmental trajectory as a collective species has us blurring the lines that separate the ‘human’ from the ‘non-human’ elements in our world as humanity grows towards a more technologically advanced but equally environmentally dependent people. Thus, the currently existing systems of ethics that govern the relationship between the ‘human’ and ‘non-human’ must be called into question. This paper aims to illustrate the positive effects of a posthumanist worldview on issues such as environmental sustainability, partnership, moral accountability and reciprocity ethics in the context of modern science and modern scientific research.

Transitioning from elementary to middle school is a time of particular vulnerability for students with behavior problems. This study examined the effects of class-wide function-related intervention teams (CW-FIT) in three middle school classrooms to determine whether this multitiered intervention could help teachers proactively manage student behavior. With a focus on teaching classroom expectations, delivering behavior-specific praise, and providing differential reinforcement within an interdependent group contingency, CW-FIT is designed to teach functional replacement behaviors that support students’ academic engagement. Intervention effects were assessed with seventh- and eighth-grade students from diverse backgrounds. Results, evaluated using a single-subject withdrawal (ABAB) design, indicated improved rates of on-task behavior at both class-wide and individual student levels, with corresponding increases in teacher praise and decreases in teacher reprimands. The positive way in which participants viewed CW-FIT implementation and its accompanying effects on student behaviors was consistent with earlier findings in elementary schools. Study limitations and areas for future research are discussed.

Institutionalized mentally retarded children performed on a two-choice discrimination task under one of 6 conditions of reward (response-contingent consumable, response-contingent nonconsumable, token-consumable, token-nonconsumable, token, social). The results indicated that response-contingent nonconsumable rewards were not more distracting than response-contingent consumable rewards nor was the presentation of material rewards by the token-reinforcement procedure less distracting than the response-contingent reinforcement procedure. Further, social reinforcement was less effective than response-contingent nonconsumable rewards; however, no differences were found between social reinforcement and the other material rewards regardless of reinforcement procedure.

The "Nature-human Integration" concept is the important part composed in China’s traditional culture, also is the simple world outlook and methodology. It has taken the huge and profound influence to the formation of Chinese civilization, and is the source to generate ideas for artistic designing. From the historical background of the " Nature-human Integration " concept, this paper expounds based on its artistic representations in nature, emotion, tolerance and view, and deeply elaborates on its instructive significance and positive effects in the development of modern artistic designing, pointing out that the essence of the "Nature-human Integration" concept is the lasting care to human and it stresses human must be harmonious with the natural environments: all things can be perpetuate only by endless circulation; accommodating and absorbing diverse cultures can bring permanent prosperity and luxuriance.

Abstract When making decisions, should one exploit known good options or explore potentially better alternatives? Exploration of spatially unstructured options depends on the neocortex, striatum, and amygdala. In natural environments, however, better options often cluster together, forming structured value distributions. The hippocampus binds reward information into allocentric cognitive maps to support navigation and foraging in such spaces. Here we report that human posterior hippocampus (PH) invigorates exploration while anterior hippocampus (AH) supports the transition to exploitation on a reinforcement learning task with a spatially structured reward function. These dynamics depend on differential reinforcement representations in the PH and AH. Whereas local reward prediction error signals are early and phasic in the PH tail, global value maximum signals are delayed and sustained in the AH body. AH compresses reinforcement information across episodes, updating the location and prominence of the value maximum and displaying goal cell-like ramping activity when navigating toward it.

Objective. This investigation researched the effectiveness of the PROMPT (Prompts for Restructuring Oral Muscular Phonetic Targets) method to address compensatory articulation errors in children with cleft palate. Design. Single-subject AB multiple baselines across participants and behaviors. Setting. Pediatric outpatient rehabilitation department in a local hospital in a metropolitan city. Participants. The investigation consisted of 3 participants (ages = 4:4 to 12:8) born with bilateral complete cleft lip and palate. All participants underwent several reconstructive surgeries to repair their lips and palates. Interventions. The PROMPT treatment was provided for 45 minutes 3 times a week for 4 weeks (3 weeks for Participant 2). Main Outcome Measure. Therapy sessions addressed anterior lingual speech motor phonemes across 3 tiers (syllables, words, and phrases). Results. Direct visual observation of data obtained throughout this investigation indicate potential positive effects and significant correlation between improvements in sound production at 3 tiers and the implementation of the PROMPT technique. Speech intelligibility was judged by 3 blinded listeners who were unfamiliar with children with speech disorders or with cleft palate speech. All listeners identified and judged improvement in overall speech intelligibility over the course of this investigation. Listeners examined speech samples selected from sessions 3, 6, 9, and 12. Conclusion. The findings in this investigation provide a potential relationship on the effectiveness of the PROMPT method and attainment of accurate speech productions in children with cleft palate producing compensatory articulation errors, resulting in improvement in overall speech intelligibility.
