Diagnosis of Helicobacter pylori infection in adults with intellectual disability

Helicobacter pylori infection is common among adults with intellectual disability. The acceptabilities and accuracies of different diagnostic tests in this population are unknown. We aimed to determine (i) patient acceptability and (ii) performance characteristics of serology, fecal-antigen, and urea breath tests among adults with intellectual disability. One hundred sixty-eight such adults underwent H. pylori testing with serology and fecal-antigen tests, and a portion underwent treatment. One year later, the participants were retested with fecal-antigen, serology, and urea breath tests. The numbers of specimens obtained and difficulties in collection reported by caregivers were noted. Test performance characteristics were assessed among participants and 65 of their caregivers, using serology as the reference. All participants provided at least one specimen, despite reported collection difficulties for 23% of fecal and 27% of blood specimens. Only 25% of the participants provided breath specimens; failure to perform this test was associated with lower intellectual ability and higher maladaptive behavior. The sensitivity, specificity, and positive and negative predictive values of the fecal test (baseline and 12 months versus caregivers) were 70 and 63 versus 81, 93 and 95 versus 98, 96 and 92 versus 93, and 53 and 74 versus 93%, respectively; those of the urea breath test (12 months versus caregivers) were 86 versus 100, 88 versus 95, 75 versus 89, and 94 versus 100%, respectively. With assistance, fecal or blood specimens for H. pylori assessment can be provided by most patients with intellectual disability regardless of their level of function or behavior. Only those with greater ability can perform the urea breath test. Using serology as the reference test, the limitations of performance characteristics of the fecal-antigen and urea breath tests are similar to those among a control group of caregivers.

The basal ganglia and semantic engagement: Potential insights from semantic priming in individuals with subcortical vascular lesions, Parkinson's disease, and cortical lesions

The impact of basal ganglia dysfunction on semantic processing was investigated by comparing the performance of individuals with nonthalamic subcortical (NS) vascular lesions, Parkinson's disease (PD), cortical lesions, and matched controls on a semantic priming task. Unequibiased lexical ambiguity primes were used in auditory prime-target pairs comprising 4 critical conditions; dominant related (e.g., bank-money), subordinate related (e.g., bank-river), dominant unrelated (e.g.,foot-money) and subordinate unrelated (e.g., bat-river). Participants made speeded lexical decisions (word/nonword) on targets using a go-no-go response. When a short prime-target interstimulus interval (ISI) of 200 ins was employed, all groups demonstrated priming for dominant and subordinate conditions, indicating nonselective meaning facilitation and intact automatic lexical processing. Differences emerged at the long ISI (1250 ms), where control and cortical lesion participants evidenced selective facilitation of the dominant meaning, whereas NS and PD groups demonstrated a protracted period of nonselective meaning facilitation. This finding suggests a circumscribed deficit in the selective attentional engagement of the semantic network on the basis of meaning frequency, possibly implicating a disturbance of frontal-subcortical systems influencing inhibitory semantic mechanisms.

Chinese engagement for Global Governance: aiming for a better room at the table?

The text defends the thesis that China is aware that its process of modernization is still recent and needs more growth, maturation and consolidation to assume the role and responsibilities of a regional or even a global leader. This text pursues an understanding about the Chinese stance in relation to the negotiations for the redefinitions of the International Order and the International System (and, hence, Global Governance) and, secondly, seeks to perceive the reactions of non-developed and developed countries in relation to Chinese strategies.

Intellectual Capital in a Seaport Context

This poster, which is the result of an ongoing PhD thesis project, illustrates how and why the Intellectual Capital (IC) concept can be applied to a seaport. As far as the authors are aware, most of the research in IC has been focused on individual firms. Although some recent papers examine macro-level organizations, such as regions, none exist on seaports. Also, there is a lack of research related to the ways IC is created and maintained as a dynamic process. In addition, there is a paucity of management sciences’ research on to maritime transportation and seaports. Several research questions are thus pertinent, whose answers can have important strategic and managerial implications for the seaport and its stakeholders.

Considerações prévias: distinctions between academic and intellectual goals for young children

Lilian Katz refere-se à crescente tendência nos Estados Unidos de introduzir objetivos de caráter “académico” nos programas destinados a crianças pequenas, em alternativa a programas centrados simplesmente no jogo espontâneo. Katz propõe uma terceira alternativa que desenvolva as competências de caráter intelectual nas crianças, de modo a estimular o desenvolvimento das suas mentes e as suas sensibilidades morais e estéticas. Katz propõe a introdução do trabalho de projeto com crianças desde os primeiros anos.

Cyberbullying and students' engagement in school : a literature review

Bullying is one of today’s biggest problems. Bullying is the intentional repeated aggression directed at a target individual. There is substantial evidence of the negative psychological and health outcomes associated with bullying. It occurs very frequently, especially in adolescence, and action is needed to lessen its causes and alleviate its consequences. Research has shown that behavior problems usually interact with other risk and protection factors, as well as with factors of etiological development. This book discusses the prevalence, psychological impacts and intervention strategies of bullying.

Students' engagement in schools : differentiation and promotion

The objective of this work is to present elements of the project Student engagement in Schools (SES). The team consists of 10 researchers from six Universities. Student engagement in schools is a multidimensional construct that unites affective, behavioural, and cognitive dimensions of student adaptation in the school and has influence on students’outcomes. The team of researchers conceptualized two major studies, a differential study to analyze the relations between SES and contextual factors, personal factors, student’s outcomes, and a quasi-experimental study to analyze the effects on SES of a specific intervention programmes. In study 1, the sample size is around 600 students (150 6th graders, 150 7th graders, 150 9th graders, and 150 10th graders). We shall focus on years of school transition, with rural and urban populations, on different regions of the country, and on students with different family background. We shall conduct questionnaires with national and international scales. The study 2 will involve students in 7th and 9th grade, from four classes, two of the experimental group and two of the control group. Patterns of verbal communication between a teacher and students can influence the classroom environment and SES. This model of communication would result in more effective student management and more time on-task for learning.
