In this work we analyzed whether different activations of the biceps brachii impact on the power transfer of the punch and how boxers of different skill levels activate the biceps brachii when deliver a punch according to their skill level and efficacy. Methods: we enrolled, basing on official rankings, 23 skilled (n=6) and unskilled boxers. Subjects were instructed to perform three cross punches directed to a fixed elastic target triggered by the coach whistling, and were monitored through a surface electromyography sensor (EMG) on the biceps brachii to estimate the muscular activation during the performance, and through an accelerometer placed inside the elastic impact target to estimate the impact energy. We analyzed the oscillatory content of the EMG signal in order to assess the muscular activation between skilled and unskilled boxers, and between weak and strong punches. Results: both skilled and unskilled boxers threw strong, medium and weak strikes. Skilled boxers performed better than unskilled boxers (47% vs 25% in the “strong punch” category).The EMG analysis revealed a significant increase of lower and higher frequencies (2-4 Hz and 15-17 Hz) and a decrease on the ...

Salvador Dali Meets Sigmund Freud: Paranoia, Narcissism, Snails

Research Article of American Journal of Psychiatric Research and Reviews Salvador Dali Meets Sigmund Freud: Paranoia, Narcissism, Snails John J. Hartman, Ph.D. Affiliate Professor, Department of Psychiatry and Behavioral Neurosciences, University of South Florida. This paper examines the meeting between the artist Salvador Dalí and Sigmund Freud that took place in London in July of 1938. Freud had just escaped from the Nazi regime in Austria and was about a year away from death. Dalí had been influenced by Freud’s work for many years and had sought to meet his idol on several previous occasions. The meeting, arranged by Freud’s friend, Stefan Zweig, and attended by the poet, Edward James, is noteworthy in that Dalí brought his painting, “Metamorphosis of Narcissus,” a treatise on the subject of paranoia, and sketched Freud’s head conceived as a snail. The paper offers perspectives on each of these events. The meeting is seen in the context of Freud’s artistic sensibility and his relationship to Surrealism. For Dalí the meeting served as a way to break with Surrealism and led to a revised philosophy of art. The paper concludes with the speculation that the meeting was experienced by the artist as an idealizing/envious narcissistic transference with Freud, thus replicating the theme of the painting that the artist had brought with him.

Antimicrobial Properties of Prosopis cineraria stem bark

Research Article of American Journal of Microbiology and Immunology Antimicrobial Properties of Prosopis cineraria stem bark Saif Al Ghais, Vibha Bhardwaj*, Pramod Kumbhar Environment Sustainability, Department Environment Protection & Development Authority (EPDA), Ras Al Khaimah, UAE Infectious diseases are the most common causes of morbidity and mortality in developing countries. Nowadays, medicinal plants play a major role in treatment of infectious diseases and they are easily available and more affordable as compared to synthetic compounds. The emerging trends of multidrug resistance among several groups of microorganisms against different classes of antibiotics led different researchers to develop efficient drugs from plant sources to counter multidrug resistant strains. This study investigated two different concentration of methanol extracts of stem bark of Prosopis cineraria to determine their efficacy against multidrug resistant microbes. Powdered barks of the tree were treated with methanol using hot extraction method. Crude methanol extracts of the bark of P. cineraria was investigated for their antibacterial activity against a wide range of bacteria (both gram-positive and gram-negative) by disc diffusion method. Ciprofloxacin was used as standard. Multidrug resistant (MDR) strains of Bacillus subtilis (ATCC 6633), E. coli (ATCC 8739), Salmonella enterica (ATCC 14028), Staphylococcus aureus (ATCC 6538), Pseudomonas aeruginosa (ATCC 27853) were used in the study. The methanolic bark extracts of P. cineraria showed a remarkable inhibition of the microorganisms. The potency shown by these extracts recommends their use against multidrug resistant microorganisms. The present study suggests that the methanol extract of the stem bark of P. cineraria exhibited a potential antibacterial activity against the tested microorganisms and could be a potential source of new antimicrobial agents. Keywords:  Prosopis cineraria, antibacterial, ciprofloxacin, bark, microorganisms ...

Education of Healthcare Professionals on an Integrated Care Pathway in order to Standardize Practice and Improve Outcomes for Individuals with Intellectual and Developmental Disability (IDD) who engage in Self-Injurious Behavior (SIB)

Research Article of American Journal of Psychiatric Research and Reviews Education of Healthcare Professionals on an Integrated Care Pathway in order to Standardize Practice and Improve Outcomes for Individuals with Intellectual and Developmental Disability (IDD) who engage in Self-Injurious Behavior (SIB) Dr. Regina Gentlesk Green Stockton University Asst. Professor Assurance Behavioral Health- Training & Community Outreach This paper addresses the lack of knowledge and lack of standardization for treating individuals who engage in self-injurious behavior (SIB) to the head. An evidence-based integrated clinical care pathway is described that was created for health care professionals treating individuals with intellectual and developmental disability (IDD) who engage in frequent and/or significant SIB. It is anticipated that this pathway will increase treatment team knowledge of best practices, decrease clinical variation, standardize care, and improve clinical outcomes with this vulnerable population.

Second Language Acquisition and Learning: Rethinking the Pedagogical Applicability of Stephen Krashen’s Monitor Model

Review Article of International Journal of Social Research Second Language Acquisition and Learning: Rethinking the Pedagogical Applicability of Stephen Krashen’s Monitor Model Mzamani J Maluleke1*, Aleck Mapindani2 1University of Venda. 2Greater Zimbabwe University The monitor model, being one of its kind postulating the rigorous process taken by learners of second language, has since its inception in 1977, stirred sterile debates the globe over. Since then, Krashen has been rethinking and expanding his hypothetical acquisition notions, improve the applicability of his theory. The model has not been becoming, and it therefore faces disapproval on the basis of its failure to be tested empirically and, at some points, its contrast to Krashen’s earlier perceptions on both first and second language acquisition. In this paper, the writers deliberate upon Krashen’s monitor model, its tenets as well as the various ways in which it impacts, either negatively or positively upon educational teaching and learning.

Touching and Touch Deprivation During a COVID-19 Lockdown

Research Article of International Journal of Psychological Research and Reviews Touching and Touch Deprivation During a COVID-19 Lockdown Tiffany Field1,2, Samantha Poling2, Shantay Mines2, Debra Bendell2, and Connie Veazey2 1University of Miami/Miller School of Medicine 2Fielding Graduate University Touching your kids and your partner, self-touching, and touch deprivation have had different effects on individuals during a COVID-19 lockdown. In this Survey Monkey study conducted during a COVID-19 lockdown (N= 260 respondents), 26% said they were touch deprived a lot, 21% said they were touching their kids a lot, 33 % touching their partner a lot, and 32% self-touching a lot (e.g. yoga and stretching). Correlation analyses suggested that touch deprivation was related to scores on the Stress, Anxiety, Depression, Fatigue, Sleep Disturbances and PTSD scales. The three types of touching were positively related to scores on the Health Scale, at home projects, and outdoor exercising with others. Touching partner was also related to lower scores on the Stress, Depression, and PTSD Scales and Self-touching was related to lower scores on the Fatigue and Sleep Disturbance Subscales. The results of these data analyses are limited by the self-reported data from a non-representative, cross-sectional sample. Nonetheless, they highlight the negative effects of touch deprivation and the positive effects of touching your kids and partners and self-touch during a COVID-19 lockdown.
