“…It was notable that training caregivers seemed to be just as effective as delivering the intervention directly to participants. Eight studies used a technique called “Meditation on the Soles of the Feet” (e.g., Singh, Lancioni, Winton, et al, 2008; Singh, Singh, et al, 2011). Four studies considered the impact of therapeutic approaches (ACT and DBT) on participants with IDs.…”

“…Other studies found reduced levels of stress in participants (Adkins, Singh, Winton, McKeegan, & Singh, 2010) and in parents (Singh, Lancioni, Winton, Singh, et al, 2007), reduced depression and anxiety (Adkins et al, 2010; Beauchemin, Hutchins, & Patterson, 2008), reduced obsessive thoughts (Brown & Hooper, 2009), decreased self-injury (Singh, Lancioni, Winton, Fisher, et al, 2006), injury to staff (Singh, Lancioni, Winton, et al, 2008; Singh, Wahler, Adkins, & Myers, 2003), weight loss (Singh, Lancioni, Singh, et al, 2008; Singh, Lancioni, Singh, et al, 2011), smoking cessation (Singh, Lancioni, Winton, Singh, et al, 2011), reduced self-reports of deviant sexual arousal (Singh, Lancioni, Winton, Singh, et al, 2011), and a decrease in staff management of aggression through restraints and medication (Singh et al, 2003; Singh et al, 2009; Singh, Lancioni, Winton, Curtis, et al, 2006). Singh, Lancioni, Winton, Singh, et al (2011) observed that a previous participant in a mindfulness-based intervention (Singh et al, 2003) independently began to teach his peers how to use the technique of “Meditation on the Soles of the Feet” (Singh, Singh, et al, 2011) to control their anger.…”

“…Of the 18 studies, 12 (67%) were conducted by the same group of researchers (Nirbhay Singh and colleagues) from the ONE Research Institute in Virginia, USA, and the American Health and Wellness Institute, also in Virginia, USA. These studies have similar methods, tending to use multiple baseline designs and standardized staff or parent mindfulness courses (delivered across 5 days to 12 weeks), or “Meditation on the Soles of the Feet” training (Singh, Singh, et al, 2011). All of these articles outline their intervention clearly in terms of describing the data collection, defining the dependent variables, and detailing the mindfulness-based intervention.…”

“…Singh et al found that as the mindfulness training progressed, the use of restraints decreased to almost no use at all. Similarly, Singh, Lancioni, Winton, Singh, et al (2007) found that aggressive behavior decreased with training in “Meditation on the Soles of the Feet”—an exercise in which participants are asked to focus on the soles of their feet to shift their attention and awareness to a neutral part of their body (Singh, Singh, et al, 2011). Furthermore, effects were maintained for at least 2 years (see also Singh, Lancioni, Winton, et al, 2008).…”

A number of studies have used mindfulness-based interventions to influence the behavior of people with intellectual disabilities, to improve their quality of life, and to reduce challenging behavior. The present review critically evaluates 18 studies and assesses the clinical and academic impact of their findings. Strengths identified included replicable methodological approaches, use of multiple baseline designs, strong construct and criterion validity, and consideration of the mechanisms by which mindfulness influences behavior change. Limitations included a lack of randomized controlled trials, inclusion of qualitative data without structured analysis, limited use of statistical analyses, and problems with sampling leading to difficulties generalizing findings. There was also a paucity of research investigating the impact of "Dialectical Behavior Therapy" and "Acceptance and Commitment Therapy" and the role of mindfulness within these approaches. Further research is warranted in this regard.

“…In addition, the increase in leaf area creates a state of shading, but the biggest negativity is needed for more quantities of water to compensate the deficit resulting from the process of Evapotranspiration (ET) during the day and this is directly related to the leaf area and roots depth (3,19). The basis of the dehydration effect is to reduce the efficiency of photosynthesis because of the imbalance between the production and deletion of efficient oxygen species (ROS), which allows them to accumulate in plant cells and tissue reflecting negatively on the nucleus, membranes, proteins and other cellular components (23). The effectiveness of the kinase protein group that plays an important role in cellular cycle regulation under the influence of dehydration may also be affected, which reduces the number of natural cell divisions and thus limits leaf growth.…”

THIS STudy was aimed to induce genetic variation toward drought tolerance after treatment with EMS as a mutagen to two maize inbred lines and their single hybrid. The experiment was carried out at Abo-Ghraib Research Station, Baghdad during the spring season of 2019. The experiment included three irrigation intervals 7, 9 and 11, four concentrations of EMS (0, 50, 60, and 70 mM) and three maize genotypes distributed in three replications using randomized complete block design (RCBD) with split-split plot arrangement which included three irrigation intervals 7, 9 and 11 days occupied the main plot, while the sub plots included three maize genotypes, and four EMS concentrations which were distributed in sub-sub plots. Results were revealed significant differences among EMS treatments and irrigation interval treatments. The inbred line 5 in control treatment showed a significant increase in days for both anthesis and silking (70.11 and 71.94) days, respectively. Plants of Nahrain hybrid also showed a super performance in plant height, leaf area, and number of rows ear-1, with a mean of 154.47cm, 746.31cm2 and 17.83 row ear-1, respectively. The irrigation intervals of 9 and 11 days were significantly decreased the mean performance of genotypes, compared to the shortest irrigation interval (7 days) which had highest mean in most traits. None treated plants (0 mM EMS) had a significant effect on the performance of most studied traits, except the anthesis and silking time, which gave the highest values under the concentration 60 mM with 69.11 and 70.48 days, respectively. Hybrid plants interacted significantly with the EMS concentration of 0 mM producing the maximal means of plant height and leaf area (169.56cm and 759.78cm2 respectively). On the other hand, the hybrid was significantly interacted with the shortest irrigation interval in the mean traits of plant's height and leaf area (163.50 cm and 757 cm2, respectively). The triple interaction between hybrids, shortest irrigation interval and EMS concentration of 60 mM had significantly increased leaf area reached 769.67cm2, meanwhile the triple interaction between hybrid plants, shortest irrigation interval, and the EMS concentration of 0 mM recorded the highest value of plant yield (199.67g). It can be concluded from the current study that the genotypes differed in their response to 9 and 11 days irrigation intervals, with a negative effect of the later interval on the vegetative and yield traits of maize compared with shorter irrigation interval.

Visible‐Light‐Mediated Oxidative Desulfurization‐Oxygenation in Cyclic Thio‐Amide

Visible‐light assisted a very simple and mild protocol for photocatalytic oxidative transformation of thioamide to amide group has been realized in cyclic system. For this purpose 5‐arylalkylidene‐rhodanine derivatives were chosen as model substrates to afford thiazolidine‐2,4‐diones. Light mediated reactions are intrinsically beneficial, since activation occurs by cleanest energy source light. Here K2S2O8 is used as terminal oxidant which does not leave any hazardous and corrosive waste to discard after the reaction fostering the practices of green chemistry. This is the first report of conversion of thioxo group in rhodanine derivatives into the corresponding oxygen analogue by visible light photo‐catalytic method. The reaction was very general since various 5‐arylalkylidene‐rhodanines underwent the reaction smoothly affording high product yields. Moreover, the broadness of this protocol was further established by applying this reaction on other systems like 3,4‐dihydropyrimidine‐2(1H)‐(thio)ones.
