Internet-Based Support and Coaching for Adolescents and Young Adults with Neuropsychiatric Disorders—The Implementation of an Intervention from an Organizational Perspective  [PDF]
Nanna Gillberg, Elisabet Wentz
Health (Health) , 2017, DOI: 10.4236/health.2017.91006
Abstract: There is a documented and often unmet need for interventions aimed at supporting young people with attention-deficit/hyperactivity disorder (ADHD) and/or autism spectrum disorder (ASD) in their transition between adolescence and adulthood. Difficulties with social interaction, initiation difficulties, and impairments in executive function can complicate visits at a clinic, i.e. traditional treatment, for individuals with neuropsychiatric disorders (NPD). A model for internet-based support and coaching aimed at young people with ASD and/or ADHD was developed and tested at three treatment sites in western Sweden. The implementation was analyzed against an inventory according to which implementations are more likely to be successful if an intervention: 1) has advantages compared to other existing methods, 2) matches the individual and organizational values, norms and work practices of its recipients, 3) is perceived as easy to use, and 4) is adaptable to local conditions and the recipients’ needs. Data were collected through group interviews with professionals involved in the implementation of the intervention. The implementation of the intervention showed promising results on measures such as access, delivery/quality of healthcare services, and equality of distribution of healthcare services. The identified impediments to successful implementation related to a wide range of factors and levels, including the design of the intervention, technical issues, attitudes of staff, organizational culture, and organizational structure at the implementation sites in terms of patient stock, work division, and resource allocation. The results are consistent with previous studies that stress the need for multi-component implementation strategies.

Abstract: To assess a carbapenem-based de-escalating strategy in nosocomial pneumonia (NP), a prospective observational study was conducted in critically ill patients with NP treated empirically with imipenem ± aminoglycoside/glycopeptide in 24 intensive care units of Spanish general hospitals. Overall, 244 patients were assessable (91% with late-onset NP). The primary outcome was therapeutic success 7–9 days post therapy.Microbial identification – based on cultures of tracheal aspirates in 82% of patients, cultures of protected specimen brush in 33%, and cultures of bronchoalveolar lavage in 4% – was only available for 131 (54%) patients. Initial antibiotics were inadequate for 23 (9%) patients. Of the remaining patients, antibiotics were streamlined in 56 (23%) patients and remained unchanged in 14 (6%) patients based on microbiology data, in 38 (16%) patients despite microbiology data favouring de-escalation, and in 113 (46%) patients due to unknown aetiology. Overall, de-escalation was implemented in only 23% of patients with potentially multiresistant pathogens, compared with 68% of patients with the remaining pathogens (P < 0.001). Response rates were 53% for patients continuously treated with imipenem-based regimens and 50% for the de-escalated patients. Higher Acute Physiology, Age, and Chronic Health Evaluation II scores were associated with greater mortality, whereas adequate empiric antibiotic therapy protected against fatal outcomes. No increase of superinfection rates caused by emerging pathogens was observed. The costs associated with de-escalation were mainly dependent on the duration of hospitalization.This study mainly highlights the current practice of a specific algorithm of de-escalation solely based on the available microbiological data, and highlights the barriers to using it more widely. In this setting, de-escalation was less likely to occur in the presence of potentially multiresistant pathogens. Prior antibiotic administration and the low use of bron

Abstract: postembryonic development of misumenops pallida (keyserling) (araneae, thomisidae), one of the most abundant predator species in soybean fields in buenos aires province (argentina) was studied. the life cycle was observed in the laboratory from egg sacs collected in the field, and from egg sacs spined in the laboratory by gravid females collected in the field. results indicated that instar length and feeding rate increased throughout the life cycle being higher in females than in males. greater mortality was observed to third and fourth instars decreasing thereafter. these results may contribute to deternmine the efficiency of this species as a natural enemy of insect pests of soybean.
Climate and Tickborne Encephalitis
Elisabet Lindgren
Ecology and Society , 1998,
Abstract: Climatic changes are projected to alter the abundance, dynamics, and geographical distribution of many vector-borne diseases in human populations. Tick-borne diseases such as Lyme disease and tick-borne encephalitis (TBE) are a growing concern in northern Europe and the United States. The impact of a future climate change on the transmission of tick-borne diseases is not known. To make such assumptions, more empirical data are needed on the relations between short-term fluctuations in contemporary weather and disease incidence. This paper analyzes relations between daily minimum and maximum temperatures, monthly precipitation, and TBE incidence during a 36-yr period in Stockholm County, a high-endemic region for TBE in Sweden. Multiple regression analyses were performed, with temperature variables expressed as number of days per winter or spring - summer - fall season with temperatures above, below, or in the interval between different temperature limits. The limits used for daily minimum temperatures represent bioclimatic thresholds of importance for pathogen transmission. To adjust for the length of the tick's life cycle, each TBE incidence rate was related to meteorological data over two consecutive years. Results reveal that increased incidence of tick-borne encephalitis is related to a combination of two successive years of more days with temperatures permitting prolonged seasonal tick activity and, hence, pathogen transmission (i.e., daily minimum temperatures above 5oC-10oC), and a mild winter preceding the year before the incidence year (i.e., fewer winter days with minimum temperatures below -7oC). Alternative explanations of the results are discussed. Findings of this study suggest that a climate change may extend the seasonal range and intensify the endemicity of tick-borne diseases, in particular, at northern latitudes.
V lkomna (n stan) allihopa! Mellan kategoriserade olikheter och radikal skillnad

Abstract: Welcome (almost) everyone! Between social categories and radicaldifference. This article explores the dilemmas involved in welcoming differences in education without simultaneously fostering structural conditions that reproduce discrimination and intolerance. Taking an excerpt from Fanny Abj rnsson’s doctoral thesis I en klass f r sig (2004) and Jacques Derrida’s deconstructions of the concept of hospitality as points of departure, the article unfolds in three parts. First, I make a distinction between two ways of responding to the otherness of the other: a conditional welcoming of social categories, and an unconditional welcoming of radical difference. These are further explored in part two. In part three I turn to he “double responsiveness” Derrida highlights as inherent in the paradoxes of hospitality, and ask how it is possible to act within this tension in relation to education. I argue that the welcoming of differences in education demands sensitivity to ambiguity and uncertainty, as well as tact and improvisation in concrete pedagogical situations.

Monoidal structure of the category of u$_q^+$-modules
Elisabet Gunnlaugsdottir
Mathematics , 2000,
Abstract: We study the finite dimensional modules on the half-quantum group u_q^+ at a root of unity q, whose action can be extended to u_q (quotient of the quantized enveloping algebra of sl_2). We derive decomposition formulas of the tensor product of indecomposable u_q^+-modules, which includes the cases of the universal and the quantized universal enveloping algebra of sl_2 for q not a root of unity. We also prove that simple modules on u_q correspond exactly to the extendable non projective u_q^+-modules. We thus establish decomposition formulas for the tensor product of simple u_q-modules.
Local infusion of low, but not high, doses of alcohol into the anterior ventral tegmental area causes release of accumbal dopamine  [PDF]

The mesolimbic dopamine system consisting of dopaminergic neurons projecting from the ventral tegmental area (VTA) to the nucleus accumbens (N.Acc.) mediates the reinforcing effects of addictive drugs including alcohol. Given that VTA is a heterogeneous area and that alcohol, in rather low doses, interacts directly with ligand-gated ion channels, we hypothesised that low, rather than high, doses of alcohol into the VTA activate the mesolimbic dopamine system and that alcohol may have different effects in the anterior and posterior parts of the VTA. The present study was undertaken to investigate this hypothesis. The present series of experiment show that infusion of a low dose of alcohol (20 mM) into the anterior, but not posterior, part of the VTA increases accumbal dopamine release in rats. In addition, higher doses of alcohol (100 or 300 mM) into the anterior or posterior part of the VTA do not affect the release of dopamine in the N.Acc., suggesting that low doses of alcohol can activate the mesolimbic dopamine system via mechanisms in the VTA. These data contribute to understanding the neuronal mechanisms underlying the dependence-producing properties of alcohol and could tentatively contribute to that new treatment strategies for alcohol use disorder can be developed.

The False Problem of the Maintenance of Sex (Review of the Original Approach)  [PDF]
Jose Maria Mancebo Quintana
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.519297
Abstract: We analyze here the keys of the original approach about the twofold cost: the return to the asexuality starting with a mutant female, with the same reproductive capacity than a sexual one, and with double genetic-reproductive success. We propose a new approach in which 1) all individuals in a population have regulatory mechanisms of reproductive mode, and when such change occurs, it happens in all its population at the same time; 2) after a change of reproductive mode in the population there can be variations in average offspring per female, according to the environmental quality; and 3) the genetic-reproductive success of the males and its unequal paternity success are accounted for. Results: The most advantageous reproductive strategy depends on the demographic situation of the population and the degree of the unequal paternity success of males. For harem values observed in nature and in populations with moderate growth rate, stable or decreasing population, the sexual strategy is advantageous. If the population growth rate is high, the asexual strategy is advantageous. In species subject to high demographic fluctuations the best strategy depends on the ability to predict the time of occurrence of the population bottleneck: if predictable, the best strategy is the alternation of generations, if not, permanent parthenogenesis.
A rela??o da tarefa de erro intencional com o desempenho ortográfico da crian?a considerados os aspectos morfossintáticos e contextuais da língua portuguesa

Estudos de Psicologia (Natal) , 2006, DOI: 10.1590/S1413-294X2006000100005
Abstract: this study examines the effectiveness of the intentional misspelling task in predicting 2nd and 4th graders' orthographic knowledge. the intentional misspelling task consists in the intentional spelling mistakes made by children in their written production. therefore it is possible to evaluate children's orthographic knowledge since some knowledge of the orthographic rules is necessary to make intentional spelling mistakes. three spelling rules in brazilian portuguese were investigated: a morphosyntactic rule (the use of the suffixes esa, oso and eza) and two contextual rules (the use of r and rr; the nasalization before consonants). the results indicated that schooling is related both to children's spelling skills and to their competence in making intentional spelling errors. on the other hand, the intentional misspelling task gives us useful information about children's orthographic knowledge in the orthographic contexts they consider to be problematic.
