Maternal Postpartum Sleep Disturbance and Fatigue: Factors Influencing

Background: Prevention of postnatal maternal sleep disorders in women is an important component of comprehensive health service delivery because of the substantial potential benefits for population health. Aim: The aim of this study is to assess the prevalence, causes and pattern of sleep disturbance, fatigue, and find out the relation between, socio-economic factors and the pattern of sleep and fatigue among maternal postpartum. Subject & Methods: This cross-sectional analytic study was carried out at Sheikh Zаyed Hospital, and Helwan General Hospital, Egypt; on 250 postpartum primiparous women in reproductive age who delivered vaginally. Three tools were used for data collection; an interview questionnaire form, the Globаl-Sleep-ΑssessmentQuestionnaire (GЅΑQ), and the Multidimensional-Fatigue-Ѕymptom-Inventory-Ѕhort-Form (MFЅI-ЅF). Results: The results revealed that sleep disturbance and fatigue were significantly higher among women who were working, urban living, with high crowding index and among those who didn't receive postnatal instructions. Α statistically significant positive relationship between the sleep disturbance and fatigue scores was observed. Conclusion: Sleep disturbance and fatigue are positively and significantly correlated. Receiving postnatal instructions decrease both sleep and fatigue problems. Recommendations: It is recommended nurses to give more importance to instructing women regarding postpartum period, and help women to cope with the problems encountered. The discharge plan must include all details and instructions for the women regarding rest and sleep. Further research is proposed to assess the effect of nursing interventions to help women who have postnatal sleep disturbances and fatigue to cope with these problems.
The use of social network analysis software to analyze communication patterns and interaction in online collaborative environments

Social network analysis software such as NodeXL has been used to describe participation and interaction in numerous social networks but has not yet been widely used to examine dynamics in online classes, where participation is frequently required rather than optional and participation patterns may be impacted by instructor requirements as well as participants’ intrinsic engagement with the subject matter. Such analysis can be valuable in programs focused on teaching collaborative and communicative skills, including teacher preparation programs, to provide information about instructional practices likely to facilitate student interaction and collaboration across diverse student populations. This exploratory study used NodeXL to visualize students’ participation in an online course, with the goal of identifying (1) ways in which NodeXL could be used to describe patterns in participant interaction within an instructional setting and (2) identifying specific patterns in participant interaction among students in this particular course. In this sample, general education teachers demonstrated higher measures of connection and interaction with other participants than did those from specialist (ESOL or special education) backgrounds, and tended to interact more frequently with all participants than the majority of participants from specialist backgrounds. We recommend further research to delineate specific applications of NodeXL within an instructional context, particularly to identify potential patterns in student participation based on variables such as gender, background, cultural and linguistic heritage, prior training and education, and prior experience so that instructors can ensure their practice helps to facilitate student interaction in light of each of these potential variables.
Detection of Eavesdropping Attack in UAV-Aided Wireless Systems: Unsupervised Learning With One-Class SVM and K-Means Clustering

A wireless relaying system in the presence of an active eavesdropper is considered. The system is assumed to use an unmanned aerial vehicle (UAV) as a relay and the uplink phase is for authentication. The active eavesdropper is assumed to sneak into the system by attacking the UAV during the process of authentication. To detect the eavesdropping attacks, we consider building predictive models with one-class support vector machines (OC-SVM) and K-means clustering. To prepare datasets for training predictive models, we propose a framework for creating the features of testing data from wireless signals and another framework for generating training data. Our results show the superiority of OC-SVM over K-means in terms of stability, while K-means clustering is better when the eavesdropper uses high power in transmission.
A SCALABLE HAPTIC FLOOR DEDICATED TO LARGE IMMERSIVE SPACES

We present a haptic ﬂoor composed of tiles with independently controllable vertices and designed to cover arbitrary large ﬂat surfaces. We describe the signal distribution architecture, based on SATIE, our spatialization engine and SWITCHER , our low latency and multichannel streaming engine. The paper also provides a description of several approaches of content authoring when such a ﬂoor is deployed in an immersive space. These approaches emphasizes the correlation among immersion modalities such as continuous localization of sound from the speaker system to the ﬂoor and continuous physical effect from the video projection to the ﬂoor.
MOLECULAR DIVERSITY OF 3 Allium spp . LOCAL RACES BASED ON RAPD DATA AND ASSESSMENT OF SSR MARKERS IN CROSS-SPECIES TRANSFERABILITY

To understand the extent of genetic diversity among local races of Allium species is an important prerequisite for proper plant conservation and genetic resource utilization. This study was conducted to assess the genetic relatedness and diversity in 10 onion (A. cepa L.), 4 garlic (A. sativum L.) and 3 bunching onion (A. fistulosum L.) local races representing various states in Nigeria using eight RAPD markers. In addition, the study included the evaluation of cross-species transferability in the 3 Allium spp. based on six expressed sequence tag (EST-SSR) bulb onion and three genic Welsh onion SSR markers. All the RAPD markers were polymorphic, the total of 66 alleles detected ranging from 4 to 10 (mean 8.25) alleles per locus. Across all the loci, the resolving power (Rp) for the RAPD markers varied from 2.11 to 5.05 (mean 4.18). The results showed that the 3 Allium species contained considerable moderate genetic diversity. Hierarchical neighbor-joining cluster analysis (NJ) based on Jaccard’s dissimilarity matrix of the RAPD data clustered the 17 local races into three major groups (GI, II, III) corresponding to species types, two of which (GI and GII) were further divided into two sub-groups. Furthermore, the factorial analysis clearly showed three groupings, each group represented each type of species used in the study which were similar to the groupings in the NJ-based clustering with some minor differences. In total, the frequency of transferability of EST-SSR and genic SSR loci was from 65 to 100 % and 47 to 100 % respectively across all local races. A total of 13 alleles were detected using the EST and genic SSR loci in the 17 local races, ranging from 1 to 3 with an average of 2.3 alleles per polymorphic locus. Six of those 9 primer pairs were monomorphic in the 17 local races. This assessment demonstrated the potential of RAPD markers in elucidating clear genetic relationship and diversity among the studied species. This result suggests that these SSR markers could be used to analyse the genetic diversity and phylogenetic relationships in a large set of Allium species in the future.
Title Chronic Traumatic Encephalopathy Presenting as Alzheimer ' s Disease in a Retired Soccer Player Permalink

The relationship between soccer and chronic traumatic encephalopathy (CTE) is not well established. Clinicopathological correlation in an 83-year-old retired center-back soccer player, with no history of concussion, manifesting typical Alzheimer-type dementia. Examination revealed mixed pathology including widespread CTE, moderate Alzheimer's disease, hippocampal sclerosis, and TDP-43 proteinopathy. This case adds to a few CTE cases described in soccer players. Furthermore, it corroborates that CTE may present clinically as typical Alzheimer-type dementia. Further studies investigating the extent to which soccer is a risk for CTE are needed.
Reading Business Process Models the more Expert Way

Business process models represent complex visual graphics, which often require training and expertise to be read and interpreted appropriately. As experts in this domain have a perceptual advantage based on a higher visual span and access to complex schemas in long-term memory, they faster reach task-relevant information and avoid task-redundant focusing on task-irrelevant information. In business process modeling, visual cues are used to guide readers to relevant information. However, visual cues are often not based on what we know about how experts read visual graphics. Therefore, we review eyetracking and think-aloud studies for visual graphics and business process models to describe expert strategies when reading business process models. Based on these strategies, we derive implications that will support novices to obtain a more expert view when reading business process models. Our suggestions include different segmentation needs and how experts’ reading strategies can be integrated into visual cueing strategies.
IMPROVED TAXANES PRODUCTION IN CALLUS CULTURES OF Taxus baccata

In this study, callus cultures from leaves and young shoots of Taxus baccata L.were established in Gamborg’s B5 medium supplemented with 2,4-dichlorophenoxiacetic acid (2 mg/L), kinetin (0.5 mg/L) and gibberellic acid (0.25 mg/L). Callus growth and taxane production were evaluated using two culture media: Woody Plant Medium and Gamborg’s B5 supplemented with picloram (2 mg/L), kinetin (0.1 mg/L) and gibberellic acid (0.5 mg/L). The effect of the inoculum size (50, 100 and 150 g FW/L) and culture media (Woody Plant Medium and Gamborg’s B5) with and without the presence of methyl jasmonate (100 M) on T. baccata cell suspensions was assessed. Taxane analysis revealed that the calus in Gamborg’s B5 produced taxol (50 g/g DW), baccatin III, 10-deacetyl baccatin III and 10deacetyl taxol. Woody Plant Medium also induced the production of taxol, although to a lesser extent. The optimum inoculum size was 50 g FW/L. In cell suspension cultures, both media had a significant effect on taxane production when supplemented with methyl jasmonate. In WPM, at day 14, a total concentration of 185.35 g/L of taxol, 172.98 g/L of baccatin III, 658.97 g/L of 10-deacetyl baccatin III and 259.75 g/L 10-deacetyl taxol were obtained, with total excretion of baccatin III and 10-deacetyl taxol to the culture medium. The best culture conditions for producing taxol were found to be WPM supplemented with MeJ. The taxol level achieved in these conditions was 3.4 higher than in the same medium without elicitation and over 9 times higher than in the cultures grown in B5, elicited or not.
Emotion Regulation in Families of Children with Behavior Problems versus Nonclinical Comparisons

Emotion Regulation in Families of Children with Behavior Problems versus Nonclinical Comparisons Lauren Borduin Quetsch The following study explored the relationship between emotion regulation in children with and without externalizing behavior problems and their caregivers. The study examined emotion regulation in both clinical and comparison samples. The main research question for the study was determining if there was a link between parent and child emotion regulation in both clinical and comparison samples. Sixty families were collected from two rural populations in the United States. Families referred for parent training with children ages 2 through 8 were recruited for a clinical sample (n = 34) along with a nonclinical comparison group (n = 26). A blocking design was used. The sample was largely Caucasian (73.3%), boys (71.7%), aged 4.62 years. Parents completed measures related to child behaviors, parenting stress, and child and parent emotion regulation at a single time point. Family behaviors were also coded during structured behavioral observations. Analyses indicated higher rates of problem behaviors in the clinical group, higher rates of parenting stress, higher levels of parental emotion dysregulation, and higher levels of child emotion dysregulation. Parents of children in the clinical sample also used more negative verbalizations with their children. Parent emotion regulation was found to be correlated with child emotion regulation, parenting stress, child behavior problems, and parental use of negative speech toward their child during play situations. Findings from this research indicate a need to target and measure outcomes for emotion regulation in both parents and their children when working with families who are referred for treatment of child behavior problems.
Uterine sarcomas in Dakar: Epidemiological and histopronostic aspects of a Senegalese study of 17 cases

Aims: Uterine sarcomas account for about 1% of all malignant tumors of the female genital tract. They are rare tumors characterized by a great histological heterogeneity and a bad prognosis. The aim of this work was to describe the epidemiological profile and histopronostic characteristics of uterine sarcomas diagnosed in the pathological anatomy and cytology laboratories of the hospitals of Dakar. Methods: We have conducted a retrospective and descriptive study of the uterine sarcomas over a period of 10 years. Patients were regrouped from the histological reports of the anatomy and cytology laboratories of Dakar. All patients with a histological diagnosis of uterine sarcomas were included. For each of the patients, special interest was in epidemiological and histopronostic aspects. Results: Seventeen (17) patients were identified. All patients were of black race, 82.3 of whom were in a postmenopausal stage. The average age was 56.3 years. Leiomyosarcoma was the most common histological type, followed by endometrial stromal sarcoma, carcinosarcoma, and adenosarcoma, respectively. An immunohistochemical study was performed for seven patients.

Croatia IS BRAIN-DERIVED NEUROTROPHIC FACTOR ( BDNF ) VAL 66 MET POLYMORPHISM ASSOCIATED WITH OBSESSIVE-COMPULSIVE DISORDER ? A META-ANALYSIS

Background: Brain-derived neurotrophic factor (BDNF) polymorphism plays an important role in neural survival and was proposed to be related to obsessive-compulsive disorder (OCD). Genetic association studies of the BDNF Val66Met polymorphism (rs6265) in OCD have produced inconsistent results. A meta-analysis of studies was conducted to compare the frequency of the BDNF Val66Met variant between cases with OCD and age-matched controls. Subjects and methods: Electronic databases were searched for eligible articles in English and ten studies on the association of the BDNF Val66Met polymorphism with OCD were analysed. Results: A total of ten studies involving 2306 cases with OCD and 4968 healthy controls were included. Findings indicated that the BDNF Val66Met polymorphism was not associated with OCD. But there was a marginally significant effect of the BDNF Val66Met variant on OCD in different ethnicity. Conclusion: Findings from this meta-analytic investigation of published literature provide little support for the Val66Met variant of BDNF as a predictor of OCD. Future well-powered agnostic genome-wide association studies with more refined phenotype are needed to clarify genetic influences on OCD.
Coastal Dynamics 2017 Paper No . 145 431 WAVE HEIGHT AND BATHYMETRIC CONTROLS ON SURFZONE CURRENT VELOCITY AND DISPERSION ACROSS AN EMBAYED

Forcing relationships between wave height, 3D-bathymetry and surfzone currents were investigated across an embayed beach with an alongshore energy gradient. Controls on velocity variability and dispersion over 3D bathymetry in particular are poorly understood. Breaking wave height ( ) was numerically modelled and alongshore depth standard deviation ( ) quantified three-dimensionality. Lagrangian drifters observed embayment-wide currents over a 3 h period, providing mean velocity ( ), velocity standard deviation ( ) and dispersion ( ). Positive linear relationships were found between and both ( = 0.26, = 0.002 ) and ( = 0.50, < 0.001 ). While was correlated only with ( = 0.21, = 0.01) , and was uncorrelated with and . This study contributes new methods for understanding surfzone forcing relationships and is the first attempt to examine spatially-variable surfzone dispersion.
Wind instruments synthesis toolbox for generation of music audio signals with labeled partials

Abstract. In this work a methodology is proposed and a set of software tools is released for the automatic generation of synthesized audio files accompanied with labels that describe the temporal evolution of the amplitude and frequency of each one of the partials present. The approach is to synthesize wind instruments sounds using a simple yet effective additive synthesis model based on [Horner and Ayers, 1998]. Some improvements over the original model are implemented and others suggested for future work. In the context of automatic extraction of musical content from audio, this data can be used as ground truth labels for the development and evaluation of algorithms intended for example to estimate partials parameters or track its evolution. This seems an interesting contribution, since manual annotation is a very time consuming task in this situation and a resource of this kind is not available for researchers at present.
Effective marketing outcomes of hotel Facebook pages The role of active participation and satisfaction

Purpose – The purpose of this paper is to investigate the role of overall satisfaction in the relationship between active participation and consumer behaviors that benefit hotels. It also addresses the importance of active members in estimating the effectiveness of online brand communities in social media marketing. Design/methodology/approach – This study used a convenient sampling method to collect data from individuals who were or currently are members of hotel Facebook pages. The empirical data were analyzed using structural equation modeling. Findings – The findings indicate that active members are likely to be satisfied with community participation and developed positive behaviors that benefit hotel Facebook pages, specifically willingness to promote the community to others and modify purchasing and information-searching behaviors. Practical implications – This study provides practical implications for Facebook marketers of hotels. It emphasizes the value of Facebook pages as an effective marketing tool for hotels. Marketers are advised to identify members’ needs, create special offerings that accommodate those needs, and effectively communicate and share information with members in order to increase the level of satisfaction of members of online communities. Originality/value – The importance of active participation and satisfaction for creating positive behaviors other than loyalty among members of hotel Facebook pages has been under-addressed. This study extends the existing research model of community participation in consumer-brand relationships by using satisfaction, community promotion, and behavioral changes to highlight the benefits of hotel Facebook pages.
HOW DOES ORGANIZATIONAL SIZE IMPACT ON KNOWLEDGE ACCUMULATION CAPABILITIES AND INCREMENTAL VERSUS RADICAL INNOVATION PERFORMANCE ?

While prior studies recognise the importance of knowledge accumulation capabilities in innovation performance, current research has still failed to empirically identify its role with regard to different types of innovation performance. The objective of this paper is to address this knowledge gap and to explore the relationships between internal knowledge creation and absorptive capabilities, and radical and incremental innovation performance. The study also contributes to analyzing the complex effect that organizational size has in the whole innovation process, influencing its antecedents (internal knowledge creation capability and absorptive capability) as well as its outputs (incremental and radical innovation performance), as the literature has produced inconsistent results and the issue is subject to continuing debate. This study demonstrates that incremental innovation performance is positively affected by both knowledge accumulation capabilities and size. However, results show that only absorptive capability has a positive direct effect on radical innovation performance, whereas size has a negative non-significant effect on it. The effect of size on knowledge accumulation capabilities also turns out to be mixed. It appears to increase internal knowledge creation capability, but it does not affect the absorption of new external knowledge, and thus does not help to develop radical innovations.
EFFECTS OF SUMAC POWDER ( Rhus coriaria L . ) ON GROWTH PERFORMANCE , SERUM BIOCHEMISTRY AND INTESTINAL MICROBIOATA IN BROILERS AT DIFFERENT STOCKING DENSITIES

This study aimed to evaluate the effects of dietary supplementation of sumac powder (Rhus coriaria) on growth performance, serum biochemistry and intestinal microbiota in broilers reared at different stocking densities. A total of 378 one-day-old Ross 308 male broiler chicks were subjected to a 2 stocking densities (10 and 20 chicks/m floor area; normal and high stocking density) x 3 sumac powder levels (0.0, 0.75 and 1.5 g/kg feed) factorial arrangement of treatments. Body weight and feed intake were significantly lower in chickens reared at high stocking density than normal stocking density groups (P<0.05). Moreover, feed conversion rate was negatively affected by high stocking density (P<0.05). Dietary addition of sumac powder had no effect on these variables in both stocking densities (P>0.05). Both stocking densities and the supplementation of sumac powder to the feeds had a reducing effect on intestinal weight (P<0.05). Serum total protein concentration of chickens reared at high stocking density was higher than those of the control normal groups (P<0.05). There was interaction between stocking density and dietary sumac powder supplementation for only body weight and abdominal fat pad variables at the end of the study (P<0.05). However, no differences were observed for the relative weight of liver, spleen, gizzard and proventriculus (P>0.05). In addition, alkaline phosphatase (ALP), aspartate amino transferase (AST) activities and high density lipoprotein (HDL), cholesterol and triglyceride concentration in the serum were not influenced by the any stocking density and sumac powder supplementation (P>0.05). In conclusion, our results showed that broilers exhibited low performance when reared at high stocking density and dietary supplementation of sumac powder has not prevented this decline.
