Integrability Of A Singularly Perturbed Model Describing Gravity Water Waves On A Surface Of Finite Depth

Our work is closely connected with the problem of splitting of separatrices (breaking of homoclinic orbits) in a singularly perturbed model describing gravity water waves on a surface of finite depth. The singularly perturbed model is a family of singularly perturbed fourth-order nonlinear ordinary differential equations, parametrized by an external parameter (in addition to the small parameter of the perturbations). It is known that in general separatrices will not survive a singular perturbation. However, it was proven by Tovbis and Pelinovsky that there is a discrete set of exceptional values of the external parameter for which separatrices do survive the perturbation. Since our family of equations can be written in the Hamiltonian form, the question is whether or not survival of separatrices implies integrability of the corresponding equation. The complete integrability of the system is examined from two viewpoints: 1) the existence of a second first integral in involution (Liouville integrability), and 2) the existence of single-valued, meromorphic solutions (complex analytic integrability). In the latter case, a singular point analysis is done using the technique given by Ablowitz, Ramani, and Segur (the ARS algorithm) to determine whether the system is of Painlevé-type (P-type), lacking movable critical points. The system is shown by the algorithm to fail to be of P-type, a strong indication of nonintegrability

Trauma and children: A call to action in school psychology.

Unfortunately, it is not uncommon for children or adolescents to be exposed to traumatic events. Experiences such as sexual or physical abuse, severe accidents, cancer or other life threatening illness, natural or man-made disasters, or the sudden death of a relative or peer can all result in maladaptive responses. As all children are in attendance at schools, this location seems the most logical place to meet the needs of children who have experienced these types of events. Therefore, it is imperative that psychologists working in schools have training in meeting the needs of this segment of the population. This manuscript summarizes the incidence of trauma in children, discusses the schools as a prime location for the provision of mental health services, and argues for the need to include training in trauma and trauma interventions in school psychology training programs

Surveillance and Reporting of Zoonotic Diseases: Perception of Partnership and Communication Between and Among State Animal Health Officials and State Public Health Veterinarians

The transmission of zoonotic diseases from wild and domestic animals to human beings is considered a global public health threat. Developing guidelines to establish communication between and among animal health and health public agencies is paramount. Constant monitoring of the exchange of information and the reporting of zoonotic disease episodes constitute effective surveillance techniques. However, past research has indicated that communication and reporting methods vary widely among U.S. states, with some states having minimal or no collaboration between and among animal health professionals and public health agencies. Therefore, guided by a social network theory, the current research examined whether communication structures and the assignment of roles and responsibilities between and among agencies had improved since a prior survey was conducted in 2005. Survey research was used to gather data from 41 state animal health officials and state public health veterinarians. Chi-square and Fisher’s Exact Test analyses identified a significant increase in frequency of meetings and satisfaction in communications since 2005. In addition, roles and responsibilities of the agencies as well as the agencies themselves were determined to have become more clearly defined. Based upon the analyses, the findings indicate that the perception of partnership and communication between and among animal and public health agencies has improved since 2005 with regard to zoonotic disease surveillance and reporting. This study reviewed these findings and placed them in the context of enhancing social change initiatives through improved communication, surveillance, and reporting between and among animal health officials. Finally, limitations of the study are discussed, and recommendations for action and future research are offered

The Spanish Adaptation of the Gilliam Autism Rating Scale-2: Translation and Psychometric Analysis

Autism is an increasingly prevalent developmental neurological condition that manifests in pervasive impairments in social interaction, communication, and stereotypic behavior and interests. Early identification leads to positive long-term outcomes. At present, all standardized rating instruments are written in English; therefore, the purpose of the present study was to adapt the Gilliam Autism Rating Scale-2 from English into Spanish using the state-of-the-art procedures described in the literature. The English instrument was translated into Spanish, back-translated into English, and then revised using an iterative process. The adapted instrument\u27s psychometric qualities were substantiated. An alpha coefficient of .96 verified the adapted instrument\u27s internal consistency. Results from test–retest comparisons verified the instrument\u27s time stability. The instrument\u27s discriminative validity was confirmed using analysis of variance; the autism group had significantly higher scores than did the other diagnostic groups. Factor analysis verified the construct validity as the items loaded into three clusters that corresponded to the defining characteristics of autism: social interaction, language, and stereotyped behaviors. This culturally and linguistically appropriate assessment tool could be an important instrument for autistic children with Spanish-speaking parents who would otherwise be disenfranchised in regards to early intervention services

Video self-modelling as an intervention for remediating dysgraphia in children with autism spectrum disorders

Writing is essential to human interaction. When handwriting is illegible, communication may be negatively impacted. A severe deficit in handwriting is known as dysgraphia, a problem frequently associated with autism spectrum disorder (ASD). Video self-modelling (VSM) has been proven effective for children with ASD in the strengthening of social skills, verbalizations, and daily living skills. Because VSM has demonstrated success in the acquisition of many types of skills, it may prove similarly effective for remediating dysgraphia in children with ASD. Utilizing a single-subject design methodology with three 7-8 year old children diagnosed with ASD, this study examined VSM as a treatment for improving handwriting legibility and proficiency. All participants’ legibility data showed a large effect sizes and high PNDs from baseline to treatment and maintenance phases, indicating that VSM is an effective treatment for improving and maintaining handwriting legibility in children with ASD. In addition, the social validity of the VSM treatment was established by the therapist and participants. Results are discussed in terms of applicability of VSM as an intervention with academic skills deficits in children with ASD

Beyond association: How employees want to participate in their firms\u27 corporate social performance

© 2015 Center for Business Ethics at Bentley University. Although many studies have found a positive relationship between corporate social performance and employer attractiveness, few have examined how different forms of responsibility might mediate that attraction, particularly when those social practices afford different degrees of employee participation. The current study undertook this line of inquiry by examining prospective employees\u27 attraction to three common approaches to corporate social performance (CSP) that offer increasing levels of participation: donation, volunteerism, and operational integration. Unexpectedly, findings from an empirical investigation challenged the study\u27s main hypothesis; that is, prospective employees were least attracted to firms that integrated their social and financial goals. Consequently, important implications and questions remain for both employers and business educators

Reported Perception and Clinical Diagnosis of Autism Among White and Non-White Groups

Objective: Lessen racial disparity by advancing awareness and promoting culturally competent practice related to Autism Spectrum Disorder (ASD) among racial groups to safeguard that children regardless of race, receive timely, accurate diagnosis and intervention. Evidence has been inconclusive regarding disparities in identifying and diagnosing ASD with some reports of higher incidents of delayed and missed diagnoses of ASD among underserved ethnic and racial minority groups. Thus, this study examined the relationship between the child’s race and reported perception of ASD and clinical diagnosis of ASD among White and Non-White children. Method: The sample (N=48) consisted of preschool children (between the ages 2 to 5) referred by the Child Find Project to the Psychological and School Services of Eastern Carolina (PSSEC), who completed the Pediatric Autism intakes and diagnostic forms. The MANOVA statistical analysis was used to examine whether differences existed between reported perceptions of ASD in White and Non-White groups compared to clinician’s diagnosis of ASD in White and Non-White groups based on the child’s race. Results: The results revealed an overall higher rate of diagnosis of ASD among the White group compared to the Non-White group. However, teachers’ reported perception of ASD was higher for the Non-White group, while parents reported perception of ASD was lower for the Non-White group. Conclusions: These findings revealed differences in the way ASD symptoms were perceived, which can explain the previously reported higher delayed and missed diagnoses of ASD among underserved ethnic and racial minorities.
