Separaxion anxiety in pediatric migraine without aura: A pilot study

Background: Separation anxiety (SA) can be defined as the fear reaction and protest manifested by children when the main caregivers move away from him/her or in front of unfamiliar person. SA near eight months may be considered as an important and normal phase of the correct and typical social neurodevelopment. Aims of the present pilot study is assessing the prevalence of separation anxiety in a population of patients with migraine without aura (MwA). Materials and methods: 119 children (69 males) suffering from MwA (mean age 1.78 ± 7:59) were consecutively recruited. The control population consisted of 231 (114 males) healthy subjects similar for age (7.64 ± 1:34; p = 0.768) and gender (p=0.987) The Screen for child anxiety related emotional disorders (SCARED) test was used to assess the prevalence of separation anxiety among MwA children. Results: Healthy individuals are on average less affected (mean 4.72 ± 0:32) of the Separation Anxiety Disorder respect of MwA children (mean 6.83 ± 0.97; p < 0.001) (Figure 1). Conclusion. MwA presents many psychiatric comorbidities and among ones separation anxiety may be considered in the clinical and therapeutic management of pediatric primary headache

Form and width of spectral line of Josephson Flux-Flow oscillator

The behavior of a Josephson flux-flow oscillator in the presence of both bias current and magnetic field fluctuations has been studied. To derive the equation for slow phase dynamics in the limit of small noise intensity the Poincare method has been used. Both the form of spectral line and the linewidth of the flux-flow oscillator have been derived exactly on the basis of technique presented in the book of Malakhov, known limiting cases are considered, limits of their applicability are discussed and appearance of excess noise is explained. Good coincidence of theoretical description with experimental results has been demonstrated.Comment: 10 pages, 5 figure

How community forest management performs when REDD+ payments fail

The reduced emissions in deforestation and degradation (REDD+) initiative uses payments for ecosystem services as incentives for developing countries to manage and protect their forests. REDD+ initiatives also prioritize social (and environmental) co-benefits aimed at improving the livelihoods of communities that are dependent on forests. Despite the incorporation of co-benefits into REDD+ goals, carbon sequestration remains the primary metric for which countries can receive payments from REDD+, but after more than 10 years of REDD+, many site-specific programs have failed to complete the carbon verification process. Here, we examine whether the REDD+ social co-benefits alone are sufficient to have slowed deforestation in the absence of carbon payments on Pemba, Tanzania. Using satellite imagery (Landsat archive), we quantified forest cover change for the period before (2001-2010) and after (2010-2018) the launch in 2010-2011 of Pemba island's REDD+ readiness project. We then compared rates of forest cover change between shehia (administrative units) that were part of REDD+ readiness intervention and those that were not, adjusting for confounding variables and the non-random selection of REDD+ shehia with a statistical matching procedure. Despite considerable variation in forest outcomes among shehia, the associated co-benefits with the Pemba REDD+ project had no discernible effect on forest cover change. Likewise, we did not detect an effect of socioecological covariates on forest cover change across all shehia, though island-wide human population growth since 2012 may have played a role. These findings are unsurprising given the failure to secure carbon payments on Pemba and indicate that co-benefits alone are insufficient to reduce deforestation. We conclude that better oversight of all-involved parties is needed to ensure that REDD+ interventions satisfactorily conclude the process of securing a mechanism for carbon payments, if slowing deforestation is to be achieved

Sensory perception in preschool children affected by autism spectrum disorder: A pilot study

Introduction: Autism spectrum disorder (ASD) is a behavioral syndrome caused by a developmental disorder, biologically determined, with onset in the first three years of life. The areas concerned are mainly those related to social communication, social interaction and mutual functional and symbolic play. In the last decades, different conceptions of autism have taken, also emphasizing different sensory-perceptual abnormalities as the basis of the central features of disorder. This pilot study intends to address the issue of sensory perception in preschool children affected by ASD. Material and methods: 11 ASD children were enrolled (7 males, 4 female) aged between 2.3 years and 4.6 years, (mean age 3.29 \ub1 0.72). The control group consisted of 24 typical developing children (15 males, 9 females) (mean age 3.08 \ub1 0.87). All subjects underwent assessment of sensory perceptual abilities according to the Bogdashina's Sensory Profile Checklist Revised (SPCR) evaluation (43). Results: The two groups are comparable for age (p = 0.491) and sex distribution (p = 0.755). Table 1 shows the comparison between the two groups results in the SPCR, specifically, individuals with ASD, showed significantly higher scores on near all perception areas evaluated than healthy controls, suggesting a clear perceptual impairment in ASD subjects. Only for olfactory perception two groups were comparable. Conclusions: no significant differences in behavioral reaction to smell stimulation between ASD and typical developing children, and this result could be explained according to the early age of our sample that could cause high reactivity to smell stimulation also in typical developing examined children

Inquiring into the political economy of oil palm as a global flex crop

Oil palm production and consumption, and the trade of its multiple commodities, have expanded exponentially in recent decades. This paper argues that this expansion will continue due to, and along with, the rise of ‘flexing’ among its increasing multiple uses, especially for more industrial and energy purposes. Oil palm has been extensively analysed in the context of land grabs and agrarian change, land conversion and deforestation. However, its nature as a flex crop remains unexplored, especially with respects to the convergence of global food, fuel and environmental crises. This paper provides a preliminary discussion of how oil palm fits in the flex-crop framework to analyse its enabling material and ideational bases, as well as who informs, decides and controls the nature of flexing. This is done through an analysis of the different roles played by state, corporate (private) and social actors in the flexing of oil palm across the globe. We conclude by drawing some implications for further research

Coupled Use of COSPEC and Satellite Measurements to define the Volumetric Balance During Effusive Eruptions at Mt. Etna, Italy

Mt. Etna is one of the most studied and extensively monitored volcanoes on earth (Bonaccorso et al., 2004). One of the most frequent hazards are due to the eruption of lava flows, more specifically those flows produced during flank eruptions. These eruptions potentially can produce extensive flows that can inundate densely populated communities of the lower slopes (Guest and Murray, 1979; Behncke et al., 2005). Satellite remote sensing can be used during effusive eruptions to help monitoring the volcano, by determining effusion rates of the flows, aiding in hazard management. The degassing that takes place when magma is rising to the surface can be regularly monitored using ultraviolet spectroscopic methods (e.g. Andres et al., 2001, Sutton et al., 2001). Sulfur Dioxide (SO2) fluxes have been derived from correlation spectrometer (COSPEC) measurements at Mt. Etna (Italy) on a regular basis since 1987 (e.g. Caltabiano et al., 1994; Allard, 1997; Andronico et al., 2005; Burton et al., 2005; Burton et al., in press). Previous studies have compared field-based effusion rates with the measured SO2 fluxes to determine how much of the degassed magma is erupted onto Etna’s flanks in the form of lava flows (Allard, 1997; Harris et al., 2000). However, most of these studies examine bulk volumes erupted over an eruption rather than examining the short-term variations during eruptions. Determining the amount of lava erupted and/or the balance between the amount supplied and the amount erupted remains an unresolved issue. The main objectives of this paper are to examine such short-term variations using satellite-based effusion rates along with regularly measured SO2 fluxes. Using these measurements we determine how and when the volume of supplied magma is balanced by the volume of erupted lava during individual effusive eruptions

Autonomic Regulation In Autism Spectrum Disorders

Introduction: The sinactive developmental model provides suggests a different way for the brain study by observing the children behavior. In all neurodevelopmental disorders, we can observe autonomic alteration comprising sleep disorders, meal behaviour alteration and self-regulatory impairment. These alterations/impairment are very frequent in autism spectrum disorders (ASD) (1-12). Aim of the present preliminary study is the assessment of metabolic rate in children affected by ASD. Material s and methods. 5 males affected by ASD aged 7-10 years (mean age 6.73\ub13:39), were recruited. The average score at the ADOS scale was 12.24 (SD\ub1 3.29). The control group consisted of 5 males typically developing children (TDC) aged 7 to 11 years (mean age 7.92 \ub1 3.23). Autonomic/Metabolic evaluation: Free-living daily physical activity was measured using either the SenseWear Armband in order to calculate the total energy expenditure (TEE), baseline (REE) and the metabolic physical activity for prolonged periods of time. In general, the SenseWear Armband allows objective monitoring of the lifestyle including duration and sleep efficiency. Results: ASD subjects show values of total energy expenditure (p = 0.0047) and active energy expenditure (p = 0.044) significantly higher compared to control subjects (Table 1). In addition, ASD children have a metabolic intermediate significantly higher than healthy subjects (p=0.015). (Table 1). Finally, the ASD children show a significant reduction of sleep time (p = 0.027) (Table 1). Conclusion: ASD can represents a very significant risk factor for developing sleep disorders and to high energy expenditure, although further studies are needed in this respect

Paternal shift-working and sleep disorders in children affected by primary nocturnal enuresis

Objectives: Primary monosymptomatic nocturnal enuresis (PMNE) is a common problem in childhood and studies about the sleep habits of affected children are not conclusive. Work-family conflict (WFC) results from the incompatibility between family demands and business/workplace needs. WFC can impact parental quality with many consequences on children health. Aim of study is assessing the prevalence of sleep disturbances in enuretic children, sons of work-shifters. Materials and methods: 80 children (67 males) aged 5-13 years (mean 10,43; SD \ub1 1,99), were consecutively referred for PMNE. Sleep habits were investigated with Sleep Disturbances Scale for Children (SDSC) and the results were compared with a control group of 255 (190 males) typical developing children (TDC) sons of no shift-workers, matched for age (mean 10.57 SD \ub1 1,89; p = 0.569) and sex distribution (Chi-square= 2.416; p = 0.120). Results: To evaluate statically differences among mean values of two samples, the Chi-square test was performed. Logistic regression was assessed to verify the role of paternal shift-working as risk factor for sleep disorders. p=0.05. All sleep disturbances categories were more prevalent in PMNE children sons of shift-workers than control group (Chi-square= 43.926; p<0.001); particularly 82.5% of PMNE vs. 11.76% of TDC show pathological scores for SBD category (Chi-square = 145.592; p<0.001; OR = 35,35; IC95% = 17.71-70.57); 61.25% vs 9.41% for SWTD (Chi-square = 93; p < 0.001; OR = 15.213; IC95% = 8.21-28.15); 57.5% vs 9.41% for DA (Chi-square = 82.31; p < 0.001; OR = 13.02; IC95% = 7.06-23.98); 37.5% vs 6.67% for DIMS (Chi-square = 45.476; p < 0.001; OR = 8,4; IC95% = 4.3-16.39); 26.25% vs 5.88% for SHY (Chi-square = 24.257; p < 0.001; OR = 5.69; IC95% = 2,76-11,71) and 25%c vs 5.49% for DOES (Chi-square = 23.323; p < 0.001; OR = 5,73; IC95% = 2,73-12,01). Conclusions: Our findings suggest that paternal shif-working plus PMNE children may be a relevant factor affecting sleep quality in affected children
