EFFECTS OF RIPARIAN VEGETATION INTEGRITY ON FISH AND HETEROPTERA COMMUNITIES

Freshwater ecosystems are essential to human societies. However, many anthropogenic activities have been constantly modifying these ecosystems. Such modifications can be detected and measured with the use of environmental bioindicators. This work aims to identify the effect of physical integrity of streams, riparian vegetation coverage and physical and physicochemical variables on fish and Heteroptera faunas of streams, identifying which group is a better indicator of environmental disturbance. Predictor variables were sorted into three matrices: (1) physical and physicochemical parameters of the streams, (2) environmental variables and (3) structural variables of riparian vegetation. We tested the effects of physical and physicochemical descriptors on species richness and abundance through multiple linear regressions. The effects of environmental and structural variables of the riparian vegetation were tested using ridge regressions. Physical and physicochemical variables had no effect on Heteroptera and fish communities. Environmental variables showed effect only on the community of Heteroptera. Ichthyic assemblages were not influenced by any environmental variables. Selected structural variables had no relation with the Heteroptera assemblages, neither with fish community. Therefore, we conclude that, in small Amazonian streams, Heteroptera is more sensitive to human impacts than fish. This sensibility is demonstrated by the negative relation between Heteroptera fauna and the canopy opening over the river and positively related to environment integrity. These associations were not found for icthyofauna.
Mazajak: An Online Arabic Sentiment Analyser

Sentiment analysis (SA) is one of the most useful natural language processing applications. Literature is flooding with many papers and systems addressing this task, but most of the work is focused on English. In this paper, we present “Mazajak”, an online system for Arabic SA. The system is based on a deep learning model, which achieves state-of-the-art results on many Arabic dialect datasets including SemEval 2017 and ASTD. The availability of such system should assist various applications and research that rely on sentiment analysis as a tool.
On States of Total Weighted Occupation Times for Superdiffusions

Suppose X is a superdiffusion in R with general branching mechanism ψ, and YτD denotes the total weighted occupation time of X in a bounded smooth domain D. We discuss the conditions on ψ to guarantee that YτD has absolutely continuous states. And for particular ψ(z) = z 1+β , 0 < β ≤ 1, we prove that, in the case d < 2 + 2/β, YτD is absolutely continuous with respect to the Lebesgue measure in D, whereas in the case d > 2 + 2/β, it is singular. As we know the absolute continuity and singularity of YτD have not been discussed before.
Effects of moderate whole-body hyperthermia and complementary medicine in the treatment of rheumatoid arthritis: a preliminary study

It is estimated that more than two-thirds of patients with rheumatoid arthritis (RA) use complementary and alternative medicine (CAM). The rationale for the use of some CAM therapies is supported by reasonable evidence. 8 patients with RA were included in the preliminary study. Patients received treatment that included whole-body hyperthermia, ozone major autohemotherapy, intravenous vitamin C and individual nutrition counselling for 4 weeks. The patient’s perceptions of pain, stiffness, and fatigue were measured on a 100-mm visual analogue scale and were considered as primary outcomes. In all patients, a significant improvement was seen at the end of the treatment and post-treatment. Pain and stiffness reduced over 40%, while fatigue nearly 60% for patients with RA. More importantly, the treatment was found to be safe and did not relate with any adverse events. The results of this study are encouraging and may become a platform for future planning of long-term studies with the complementary treatments in combination with existing standard therapies in RA.
Paleomagnetic research on Icelandic lava flows

Following a short review of the main efforts in paleomagnetic eld work on basement rocks in Iceland since 1950 and a description of their main magnetic characteristics, some examples of paleomagnetic research on these rocks are described. This research has had two major aims. One has concerned the stratigraphy of the lava pile, where reversals of the remanence polarity are useful in correlating between mapped proles of similar age some kilometers apart. The other aim has been to obtain information on various aspects of the geomagnetic eld conguration and its changes through the last 15 M.y. Additionally, knowledge of the magnetic properties of basement rocks is essential in the geological interpretation of magnetic anomalies. INTRODUCTION – HISTORICAL The area of research known as “Paleomagnetism” originated as the study of the Earth’s past magnetic eld, by means of measurements on stable components of remanent magnetization in rocks. For general properties of the geomagnetic eld, the reader is referred to books such as Lanza and Meloni (2006). The subject of paleomagnetism has also come to include other applications of the stable magnetic remanence directions e.g. in age estimates, regional tectonics, or rock deformation. Therefore, research which is concerned solely with actual aspects of geomagnetic elds has in recent years been referred to by the more appropriate name “Paleo-geomagnetism”. A complementary research area called “Rock magnetism” embraces the magnetic properties of rocks and minerals in general, including the mechanism of remanence acquisition. Although remanencemeasurements on samples of igneous rocks from Iceland (at 64–66◦N) were initiated before 1930, their potential for paleomagnetic purposes was rst appreciated through the work of J. Hospers in the early 1950’s (e.g. Hospers, 1953). A few years later, Sigurgeirsson (1957) and others improved the techniques of Hospers and demonstrated additional applications of lava remanence directions, both in local geological research and in a global context. Subsequently, a U.K.-Icelandic expedition in 1964–65 carried out major sampling in East Iceland (Dagley et al., 1967; Watkins and Walker, 1977). Their collection included over 850 distinct lava ows and additionally about 200 thin ow units within those lavas that were classied as compound ows. The samples were used for a variety of paleomagnetic, rock-magnetic, and dating studies. Among the accomplishments of the above pioneers we may mention: • Early applications of some key concepts, e.g. “virtual geomagnetic pole” (VGP) and “Fisher statistics” (Fisher, 1953). • Development of the alternating-eld (AF) technique for eliminating secondary viscous remanent magnetization (VRM) • Conrmation of the occurrence of geomagnetic reversals at variable intervals through the period 2–13 M.y. ago, at a rate of at least 5–6 per M.y. • Application of polarity reversals in stratigraphy across 10 km or more (Figure 1) • Demonstration of the long-term dependence of the (virtual) geomagnetic dipole moment upon VGP latitude JÖKULL No. 58, 2008 101
Random UV Mutagenesis Stimulated over Production of Citric Acid by Aspergillus niger

The Aspergillus niger strain was isolated from soil sample and employed for the production of citric acid from easily available raw materials (citrus fruit wastes). A total of four substrates-lime peels, orange peels and banana peels and beet root peels were selected in this study. The citric acid fermentation was carried out upto 6 days at 300C. Fermentation process was carried out by using three types of inoculum i.e A. niger spores and mycelium and also mutated A.niger mycelium for citric acid production. Estimation of citric acid and sugars were done by every 48 hrs. Highest yield of citric acid (10g/100ml) was observed in the mutated mycelium than the spores and normal mycelium. Among the substrates used, orange peels were found to be more suitable for citric acid production. Greatest antimicrobial activity of synthesized citric acid was observed against E.coli and Staphylococcus aureus and also trail of Calcium Hydrogen Phosphate Dihydrate (CHPD) crystal dissolution was tested. As the increased concentration of citric acid, the dissolution of CHPD crystals was found to be high.
Extended Families and Child Development : Evidence from Indonesia

This paper provides empirical evidence on whether and how resources controlled by extended family members affect child health and education using uniquely rich longitudinal data from the Indonesia Family Life Survey. IFLS contains information on resources under the control of each individual within households, and resources of individual family members who are not co-resident. By utilizing this information in the context of intrahousehold models, we provide direct empirical evidence on the role that intergenerational transfers play in human capital accumulation. Estimates are placed in the context of a theoretical model of family resource allocation that imposes few restrictions on preferences of individuals within a family. Our results suggest departures from the traditional unitary model of the family, but we cannot rule out that co-resident and non co-resident family members make allocation decisions cooperatively. The results are important for understanding family behavior and intergenerational exchanges. †We thank Joseph Hotz and Alessandro Tarozzi, as well as participants in the Duke International Population and Development Workshop, for their helpful comments and suggestions.

Modeling Recreational Demand for Land in a CGE Framework

We represent recreational demand for land in a CGE framework and apply it to investigate the potential of second generation biofuels production under possibilities of land use conversion from natural areas to agricultural land in the U.S, considering the recreational value of forests. We introduce recreational benefits of natural forests through “household” production sectors for hunting and fishing, for wildlife viewing in reserved areas, and wildlife viewing in other forest areas, based on extensive data available in the U.S. about those activities. We test the model assessing the land use changes and welfare impacts from a U.S. climate policy scenario. The new approach resulted in similar land use change as earlier work where land conversion was limited by an elasticity based on observed land supply response. The advantage of the new approach built here using recreation data is that it provides an obviously improved measure of welfare cost of policies that lead to land use change, because the preservation value of the land offsets the increased cost of the policy due to the restriction on use. The results are sensitive to the representation of people’s willingness to substitute other inputs for natural land in their recreation experience, parameter not being well investigated empirically. The main contribution of the paper is not for its insights on biofuels potential but for the improved representation of welfare changes from models where the land supply response limits conversion.
HMIAC-SURVEY ON HUMAN-MACHINE INTERACTION IN AIRCRAFT COCKPITS

With the purpose to assess the effects of highly automatic flight control systems and the automation of the pilots’ working environment in general, a questionnaire was developed at the DLR Institute of Flight Systems. In an anonymous on-line survey among professional airline pilots with more than 120 participants subjective opinions regarding the trend of ever-increasing flight deck automation were captured, addressing operational topics such as workload, situational awareness and trust as well as subjects regarding the preparation of working in highly automated environments such as suitability of checklists, procedures and flight training. The results considering the operational aspects of flight deck automation are presented in this paper.
Segmentation for Domain Adaptation in Arabic

Segmentation serves as an integral part in many NLP applications including Machine Translation, Parsing, and Information Retrieval. When a model trained on the standard language is applied to dialects, the accuracy drops dramatically. However, there are more lexical items shared by the standard language and dialects than can be found by mere surface word matching. This shared lexicon is obscured by a lot of cliticization, gemination, and character repetition. In this paper, we prove that segmentation and base normalization of dialects can help in domain adaptation by reducing data sparseness. Segmentation will improve a system performance by reducing the number of OOVs, help isolate the differences and allow better utilization of the commonalities. We show that adding a small amount of dialectal segmentation training data reduced OOVs by 5% and remarkably improves POS tagging for dialects by 7.37% f-score, even though no dialect-specific POS training data is included.
Immune Response in a Pediatric Cancer Patient after a One-Week Skiing Intervention

Moderate physical activity possesses positive effects on the immune system function. Numerous studies investigated such effects also in cancer patients. As most studies were conducted on adults, much less is known in children and adolescents. Moreover, most studies were conducted under laboratory conditions in order to control the duration and intensity of the activity. However, daily life also includes outdoor activities. The aim of the present study was to investigate immunological parameters in a pediatric cancer survivor (8 years) suffering Acute Myeloid Leukemia (AML) who underwent bone marrow transplantation. The values were compared to those of a healthy control group (CG; N = 10). Blood samples were taken at the first (pre-test) and at the last day (post-test) of a winter sports camp by using a portable flow cytometry BD Accuri C6 device. No significant changes were observed between the preand post-test in the CG. The patient showed an increase in the total lymphocyte population, and in the CD3+ and CD4+ cells, all of them being within the range of variation of the CG. NK-cells increased slightly in the patient, however, both values were below the range of variation of the CG. B-Lymphocytes decreased from a value above the range of variation of the CG to a level close to their median value. Although the intensity of the skiing activities was difficult to assess, the patient showed changes in immunological parameters which might be interpreted as an improvement of the immune system in the course of a one-week skiing intervention.
Grounded Theory in Entrepreneurship Studies : Feasibility of the Method and the Design of Research

In this paper, we discuss building grounded theory from case studies in the domain of entrepreneurship. We locate grounded theory as a research method in the umbrella of qualitative methods, also raising broader issues of its paradigmatic position. We then discuss situations where this method is feasible and recommendable. Thereafter, we review the pre-fieldwork research phase of planning and designing a study. A companion paper (Mäkelä, 2004) introduces the remaining phases of the grounded theory process, starting with a discussion on fieldwork.
Development of the Involuntary Autobiographical Memory Questionnaire (IAMQ)

Involuntary memories are experiences that come to mind without a deliberate attempt to retrieve this information. Although involuntary memories are a common and generally positive experience, vivid flashbacks and intrusive memories are major symptoms of various psychiatric disorders, such as Post-Traumatic stress Disorder (PTSD) and depression. The lifetime prevalence of experiencing a traumatic event is quite high, yet only a small proportion of individuals will experience repeated intrusive memories of this traumatic event. The current thesis focuses on developing a self-report instrument for measuring individual differences in experiencing involuntary memories (intrusive and non-intrusive memories). The goal of Study 1 is to develop the Involuntary Autobiographical Memory Questionnaire (IAMQ) and test its validity by comparing responses on this measure with scores on an intrusive memory response questionnaire and a depression questionnaire. A 17-item questionnaire was developed and tested on 785 participants. Principle Components factor analysis of the IAMQ revealed five factors: intrusiveness of involuntary memories (IN), emotional valence (EV), person focus (PF), specificity (SF), and multisensory object focus (MO). Significant positive correlations were found between the IN factor and each of the other four factors indicating intrusive memories were associated with greater emotional impact and specificity. In addition, the EV factor was significantly correlated with depression scores suggesting people who experienced higher levels of depressive symptoms were more likely to experience emotionally negative involuntary memories. The findings of Study 1 support the utility and validity of the IAMQ for measuring involuntary and intrusive memories. The goal of the second study was to compare responses on the IAMQ with responses to involuntary memories evoked by two laboratory tasks, Continuous Word Association Task (CWAT) and Traumatic Film Task (TFT). Significant relationships were found between the EV factor and mean emotional ratings of involuntary memories measured in both CWAT and TFT with 56 participants. In summary, the IAMQ was found to have adequate validity and clinical utility, and future research will examine further tests of its psychometrics and utility in clinical settings for symptom and intervention assessment.
Combination of X-Band High Resolution SAR Data From Different Sensors To Produce Ground Deformation Maps

The constitution of an archive of Synthetic Aperture Radar (SAR) data acquired over a site of interest is mandatory for PSI (Persistent Scatterer Interferometry) analysis. The application of PSI methodologies to detect ground motions requires the use of a large stack of data in order to identify the measurement points and properly separate the different phase components due to the ground motion, the topography and the atmospheric induced phase delays. When monitoring areas affected by strong gradients of deformation, the presence of unexpected gaps in the acquisitions plan can prevent from correctly measuring the motion; the maximum gradient of motion detected without ambiguity can be seriously degraded. This paper proposes an alternative, based on the combination of SAR acquisitions from different sensors. This is possible with sensors that operate similar carrier frequencies, modes of acquisition with similar resolution and with the selection of the appropriate orbital passes to obtain approximately the same observation geometry. Keeping the same geometry preserves the coherent target in the two data stacks and do not significantly affect the final density of the measurements. The approach developed has been optimized for the PSI study of a particular area of interest; the combination of two stacks of X-band SAR datasets acquired by the TerraSAR-X and COSMOSkyMed (COnstellation of small Satellites for the Mediterranean basin Observation) satellites is proposed. The feasibility of the technique is showed with real data.
Age, Growth and Mortality of the Goldlined Seabream Rhabdosargus sarba in Waters off Southwestern Taiwan

Abstract:Age, growth and mortality of the goldlined seabream, Rhabdosargus sarba, were estimated based on 593 and 6516 specimens that were collected in waters off southwestern Taiwan from September 2015 to August 2016, and April 2015 to December 2017, respectively. The body weight (BW) and total length (TL) relationship (all data-pooled) was expressed as: BW = 0.01511 TL3.0346 (r2 = 0.95; n = 593). Growth rings (identified as opaque and translucent zones) were counted on 447 sectioned sagittal otoliths using a microscope under transmitted light and were counted up to 8 (42.0 cm TL) for both sexes. Edge analysis indicated that growth rings in otoliths were deposited once per year, and the opaque zone was formed in December. The von Bertanlanffy growth function (VBGF) best fit the observed length at age data for R. sarba. The growth parameters (±standard error) of VBGF for R. sarba (all data-pooled) were estimated as: L∞ = 53.94 ± 3.71 cm TL, k = 0.217 ± 0.033 yr−1, t0 = −0.182 ± 0.167 yr (n = 447). Total mortality estimated from a length converted catch curve was 0.655 yr−1, age-specific natural mortality and fishing mortality were estimated as 0.789–0.293 yr−1 and 0.109–0.365 yr−1, respectively. The exploitation rate was estimated to be 0.440.

Etiology and Antimicrobial Susceptibility of Bace­rial Septic Arthritis and Osteomyelitis

Background: To assess the distribution and resistance of the pathogens responsible for septic arthritis and osteomyelitis over a 10 years period in children admitted to Children's Medical Center Hospital, Tehran, Iran. Methods: Microbiologic and clinical presentation reports from 145 cases of septic arthritis and osteomyelitis from March 1995 to February 2005 were retrospectively reviewed. Results: Of 145 cases, 71(49%) had positive culture: 71.8%(51/71) of organisms were isolated from synovial fluid alone, 8.4%(6/71) from blood culture alone and 19.7% (14/71) from both synovial fluids and blood cultures. Staphylococcus aureus was the most common pathogen isolated, making up 60.5% of all positive cultures, followed by Klebsiella spp. (14%) and coagulase-negative staphylococci (8.4%). Thirty eight percent of S. aureus and 84% of coagulase-negative staphylo­cocci isolates were resistant to cloxacillin. All isolates of S. aureus were susceptible to clindamycin and also, 89% were susceptible to vancomycin. Among Klebsiella spp. , amikacin was shown to be very effective, with susceptibility rates of 100%. Haemophilus influenzae was identified in only 2% of all patients. Conclusion: The present study highlights the importance of characterizing the etiology and antibiotic susceptibility of organ­isms causing septic arthritis or osteomylitis in children.
