EFFECT OF SOME SOIL AMENDMENTS ON SALINE-SODIC SOILS RECLAMATION

A leaching experiment was conducted to asses efficiency of gypsum solely or in combination with sulfuric acid and/or botanical compost on saline-sodic soils reclamation. Soil samples were collected from El-Hossainia plain, El-Sharkia Governorate, Egypt. The following treatments were designed in a randomized complete block design and performed in 8 replicates:T1: non-treated soil “NTS”, T2: full gypsum requirements “FGR”, T3: FGR + sulfuric acid “SA”, T4: FGR + SA + botanical compost 1% “BC-1%”, T5: FGR + SA + botanical compost 2% “BC-2%”, T6: FGR + BC1%, T7: FGR + BC-2%, T8: 1⁄2 gypsum requirements “1⁄2 GR”, T9: 1⁄2 GR + SA, T10: 1⁄2 GR + SA + BC-1%, T11: 1⁄2 GR + SA + BC-2%, T12: 1⁄2 GR + BC-1% and T13: 1⁄2 GR + BC-2%. Leaching was done using the intermittent method so as to add portions to the already saturated soil columns, and obtain leachates equal to the added portions. Amounts of water were calculated to reduce the initial ECe from 66 to 4-dSm for 20-cm soil according to Reeve equation. All treatments decreased soil EC, soil pH and soil sodicity expressed as SAR and ESP. Results showed that 1⁄2 GR + SA + BC-2% treatment was more effective in decreasing the pH, EC and soil sodicity than the other treatments. Efficiency of treatments were T11 < T5 < T4 < T3 < T10 < T7 < T9 < T6 < T2 < T8 < T13 < T12 < T1. This study suggests that leaching using gypsum in combination with sulfuric acid and/or botanical compost on saline-sodic soils reclamation is reliable on ameliorating salinity and sodicity or such soils.
Family context and drug use in adolescents undergoing treatment

In this study, the aim was to describe characteristics of the family context of adolescents undergoing treatment in the Alcohol and Drugs Psychosocial Care Center, Cuiabá, MT. This was a cross-sectional retrospective documental study analyzing the medical records of 74 service users receiving treatment. Results showed a predominance of males, with low levels of schooling and a high proportion of marihuana use. The majority had a satisfactory home life, did not get on well with the father figure and lived with other family members who used drugs. The findings indicate the importance of evaluating family factors in treatment, providing important information for developing comprehensive care which includes the user and their families.
Migration With Endogenous Social Networks in China

Numerous empirical studies have documented a strong association between social networks and individuals’ migration decisions. Few papers formally analyse how social networks affect both migration decisions and labor market outcomes formally. In order to understand how social networks affect individuals’ migration decisions and labor outcomes, I develop and estimate a dynamic programming (DP) model for the joint decisions of repeat and return migration, social network investment decisions and labor market outcomes. I use data on internal migration between rural and urban areas in China. The model distinguishes between the two channels: migration cost and search frictions through which social networks may affect migrations. On one hand, social networks may have a direct effect on migration costs. On the other hand, social networks may have an indirect effect on labor outcomes by the impact on job arrival rate. The estimation results show that social networks affect both channels. Individuals with networks have almost twice job arrival rate than those without networks. At the same time, social networks can reduce 10% of migration cost on average. To achieve the same government goal, policy simulations show that the government has to spend more to offset the effect of lower investment in social networks.
www.econstor.eu Vicarious Liability and the Intensity Principle

The present paper provides an economic analysis of vicarious liability that takes information rents and monitoring costs to be borne by the principal explicitly into account. In the presence of information rents or if the principal is wealth constrained herself, vicarious liability need not generate efficient precaution incentives. Rather, precaution incentives turn out to depend on the exact quantum of damages specified by courts. I shall compare incentives under three damages regimes: strict liability, the traditional negligence rule, and proportional liability. To do so, I make use of the intensity principle that allows to rank damages regimes based on the monotonicity of differences of the principal’s expected payoff as a function of induced precaution.

Validation of a microscopic model for firm location in LUTI models

This article presents a micro simulation model for the location of individual firms in a disaggregate urban environment. The model applies spatially detailed location factors that measure proximity to transport infrastructure, accessibility, and the composition of the firm population. Objective of the model is to quantify effects of spatial and transport planning scenarios on firm dynamics and mobility. The presented Spatial Firm-demographic Micro-simulation (SFM) model simulates transitions and events in the firm population, including firm relocations, firm growth, firm dissolution and firm formation. Accessibility is measured with proximity to infrastructure access points and logsums of business and commuting trips from a transport model. From urban economic literature, additional measures for ‘Marshallian’ and ‘Jacobian’ externalities are specified that measure specialisation and diversity in the firm population, integrated with travel time range bands. The SFM-model is applied in a case study for the province of South Holland in The Netherlands. The area contains a firm population of about 90.000 firms that are distributed across 70.000 6-digit zip code locations. The model is estimated on an extensive longitudinal dataset with the full firm population from 1988 to 1997. This article presents the validation of the model on similar data for the successive period from 1997 to 2004. The validation shows that the SFM-model can provide reliable estimates of firm demographic development at neighbourhood level. At micro level, the results show a dynamic pattern that seems representative for coincidence in the behaviour of individual firms. The microscopic detail of the model allows the inclusion of advanced theories from urban economics and thus provides a more advanced framework for modelling firm location in integrated land use transport interaction models.
An Investigation into Lecturers' Perceptions about Distributed Leadership in Public Universities in Nigeria

Distributed leadership has been perceived as an effective strategy toward improving the effectiveness of universities in this era of globalization. This study therefore examines lecturers' perception about distributed leadership in public universities in Nigeria. A quantitative research design was employed to collect data from lecturers in public universities in North-central geopolitical zone of Nigeria. A total of 160 questionnaires were distributed and only 101 were usable for data analysis. SPSS version 20 was used for data analysis. The findings of the study revealed that distributed leadership was not adequately practiced in the sampled universities. However, the result of the t-test analysis shows that there is no significant difference in the lecturers perception about distributed leadership based on the school type and their gender. Therefore, it is suggested that the university management should improve their effort towards distributed leadership.
CUE496-Do the Words Matter? An Analysis of the Linguistic Sentiment of Earnings Conference Calls and Abnormal Stock Returns in Brazilian Companies Autoria

In finance and accounting literature, different aspects are presented as possible factors related to stock returns. More recently, studies have been dedicated to analyzing the potential influence of the tone and sentiment of corporate reports, newspaper articles, press releases, and investor message boards on stock prices. Thus, based on assumptions of Legitimacy Theory, we investigate whether cumulative abnormal returns (CAR) on the stocks of Brazilian listed companies are associated with the linguistic sentiment of quarterly earnings conference calls. Using a sample of 78 observations related to the conference calls of 24 companies listed in the Novo Mercado segment in 2016-2017, we measured CAR using the market model and the linguistic sentiment of earnings conference calls using IBM’s Watson Natural Language Understanding platform. An analysis of the results of statistical tests such as descriptive results, correlation matrix, and correspondence analysis enables it to be inferred that, in general, there is a positive association between cumulative abnormal returns and the optimism sentiment of quarterly conference calls. Thus, it is conjectured the possibility that the speeches made by managers in conference calls legitimize company performance in the market, by altering the perception of investors in the stock market and leading to implications for the value of the stocks traded.
Factors Predicting the Culture Shock of Peace Corps Volunteers in the Western China Universities

This study investigated the factors predicting the culture shock of Peace Corps volunteers in the universities in the western China. The results revealed that length of stay and gender were not significant predictors for culture shock. Though no significant difference was found between length of stay and culture shock, length of stay in this study showed a negative predictive effect on culture shock. Education background was a significant negative predictor for culture shock. A strong correlation was found between culture shock and homesickness. Homesickness accounted for 53.5% of the variance in culture shock. Feelings toward China also were found to be correlated to culture shock and could account for 26.6% of variance in culture shock. Multiple Regression Analysis showed homesickness and feelings towards China had a direct effect on culture shock, satisfaction with the life in China had indirect effect on culture shock with homesickness and feelings towards China as mediating variables.
Role of Diffusion-Weighted MRI in Colorectal Cancer

Background: To reveal the adding value of diffusionweighted Magnetic Resonance Imaging (MRI) in the detection and differential diagnosis of the colorectal cancer, comparing the results of Apparent Diffusion Coefficient (ADC) value with histopathological studies. Aim of Study: The aim of the study was to determine the effectiveness of MRI in the diagnosis of colorectal cancers and to reveal the adding value of DWI in the detection and differential diagnosis of the colorectal cancer, comparing the results of ADC value with histopathological studies. Material and Methods: Fifteen patients with suspected colorectal cancers clinically, endoscopically or by CT and US images were included in this study. All cases have been evaluated with 1.5 MR scanner. In addition to the conventional sequences (T2-axial, sagittal and coronal weighted images (WI), axial T2 STIR, T1 WI and a Diffusion-Weighted Images (DWI) with 4 different b-values (0, 400, 600 and 1000s/mm 2 and ADC maps were obtained then the results have been compared to histopathological diagnosis. Results: All cases of malignant colorectal cancer showed high signal (restricted diffusion) on DWI. Receiver Operating Curve (ROC) analysis of ADC values yielded an Area Under Curve (AUC) of 0.912, setting a threshold ADC value of <1.1 X 10 –3 mm 2 /sec yielded a sensitivity of 82.8% and specificity of 100% in detecting the malignant colorectal masses. Conclusion: DWI with high b-values and ADC value is a feasible method and has the potential to be effective in detection of colorectal cancer.
Residual Stress Mapping in Welds Using the Contour Method

Residual stresses play an important role in determining welded structure integrity and performance. In this work we present a new method for measuring a full cross-sectional map of residual stresses. In this method, the contour method, a part is cut in two using electric discharge machining (EDM). The contour of the resulting new surface, which will not be flat if residual stresses are relaxed by the cutting, is then measured. Finally, the original residual stresses are calculated from the measured contour using a straightforward finite element model. This paper illustrates the measurement process as applied to various weldments, including several that would have been very difficult to measure using other residual stress measurement techniques. First, the contour method is validated by comparing measurements on a multi-pass Gas Tungsten Arc Welded plate to independent neutron diffraction measurements. Next, the contour method is demonstrated on plates of 37 mm thick pressure vessel steel butt-welded using Submerged-Arc Welding. The contour method is then demonstrated on dissimilar welds: stainless steel rods inertia friction (IFR) welded to aluminum rods.
The Effects of a Bioenergy Economy Based Program on Attention Bias Modification in People With High Anxiety Sensitivity

Background: According to scientific evidence, high levels of sensitivity anxiety are one of the predictors of panic attacks, anxiety, and depression. The multidimensional anxiety sensitivity (cognitive, social, and physiological) is base on cognitive biases such as attention biases which are due to selecting threatening stimuli instead of neutral or positive stimuli. Despite the initial promise, attention bias modification (ABM) has a limited effect on reducing anxiety. This study aims to modify attention bias by reducing the focus on the threatening stimuli based on Bioenergy Economy (BEE) protocol; as an integrated model of care. Methods: The present study is base on a quasi-experimental design with pre-test and post-test and follow-up in both groups. Thirty women between the ages of 23 to 50 selected from the patients referred to Bozorgmehr Neurology clinic in Mashhad. People who scored more than 70 in anxiety test, were randomly put into the experimental and control groups. The data collection tool was dotprobe test. The experimental group participated in the entire BEE protocol. Results: The mean score sensitivity anxiety of the experimental group in the pre-test, post-test, and follow-up was significantly lower than those in the control group by using multivariate analysis of covariance. Also, the mean score of the experimental group in dot-probe test, neutral reaction time, emotional response time, and interference score in the post-test phase, as well as the components of dull reaction time and sensitive response time in the follow-up and post-test were significantly lower than the control group. Conclusion: The BEE protocol is effective in ABM and reducing high sensitivity anxiety.

Leslie Citrome Yangchun Du Peter J Weiden 1Psychiatry and Behavioral Sciences, New York Medical College, Valhalla, NY, USA; 2Biostatistics, Alkermes, Inc., Waltham, MA, USA; 3Medical Affairs, Alkermes, Inc., Waltham, MA, USA Objective: Schizophrenia clinical trials commonly measure observed changes in Positive and Negative Syndrome Scale (PANSS) total score. However, it is more intuitive to think of response vs nonresponse, a binary outcome. Assessing binary outcomes enables calculation of number needed to treat (NNT) for therapeutic outcomes, number needed to harm (NNH) for adverse outcomes, and likelihood to be helped or harmed (LHH) to demonstrate benefit/ risk tradeoffs. Here, NNT, NNH, and LHH were used to evaluate the clinical usefulness of aripiprazole lauroxil in patients with an acute schizophrenia exacerbation. Methods: Categorical efficacy and tolerability data were taken from the pivotal Phase 3 trial evaluating aripiprazole lauroxil for treatment of an acute exacerbation of schizophrenia. NNT and NNH values, with 95% CIs, were calculated in this post hoc analysis. Results: Using the intent-to-treat population for the pooled doses of aripiprazole lauroxil (441 mg [n=196] and 882 mg [n=204] q4w), responder rates (≥30% improvement from baseline PANSS total score) were 35.3% for aripiprazole lauroxil arms vs 18.4% for placebo (n=196), yielding a NNT of 6 (95% CI: 5–11). Discontinuation rates due to adverse events (AEs) were higher among patients randomized to placebo than to either aripiprazole lauroxil dose. Akathisia was the only AE with an incidence ≥5% in each aripiprazole lauroxil group and at least twice that of placebo (11.6%, 11.5%, and 4.3% of the patients receiving aripiprazole lauroxil 441 mg, 882 mg, and placebo, respectively), producing a NNH of 14 (95% CI: 9–33) for pooled aripiprazole lauroxil doses vs placebo. Calculating LHH for therapeutic response vs akathisia, aripiprazole lauroxil was 2.3 times more likely to result in a therapeutic response than an incident of akathisia. Conclusion: Using metrics of NNT, NNH, and LHH, aripiprazole lauroxil was an efficacious and well-tolerated intervention in a pivotal study in patients with an acute schizophrenia exacerbation.

Anatomical redescription of Cyrenoida floridana (Bivalvia, Cyrenoididae) from the Western Atlantic and its position in the Cyrenoidea

Members of the small bivalve family Cyrenoididae inhabit brackish waters of the eastern and western Atlantic Ocean. Cyrenoida floridana (Dall, 1896) from the western Atlantic is poorly known aside from shell descriptions. A detailed shell and anatomical study of C. floridana is here presented and compared with available data for Cyrenidae and Glauconomidae, two families of closest relationship according to recent phylogenetic studies. The species is characterized by valves externally covered by thin light brown periostracum; muscle scars and pallial line (without sinus) weakly impressed on the internal shell surface; a unique hinge pattern composed of cardinal and lateral teeth joining each other, right hinge with two laterals and two cardinals forming two inverted-V-shaped teeth and left hinge with two cardinals and one lateral forming a horizontal reversed F-shaped tooth; and microtubules inside the shell walls. Anatomically, the species presents unequal adductor muscles; demibranchs fused to each other along their posterior ends; a pair of totally fused, pigmented siphons; two pairs of siphonal retractor muscles; and a stomach with conjoined style sac and intestine, a single typhlosole, and three sorting areas. Evidence of shell parasitism is described.

This study aims to (1) develop and validate a multiple choice chemical literacy test instrument (MC-CLTI) on chemical kinetics and (2) conduct a small survey on chemical literacy of first year chemistry students. The development of the instrument involved expert consultation and judgment, validation and two times pilot studies. The first pilot study involved 119 first year chemistry students while the second pilot study involved 197 second year chemistry students. The final form of MC-CLTI consists of 30 valid and reliable items (Cronbach's Alpha coefficient = 0.744). The survey showed that the average score of respondents' chemical literacy was 63.24. This score is in the range of the average scores reported by several previous studies.
In vitro Assessment the Antifungal Activity of Dissotis multiflora (Melastomataceae) and Paullinia pinnata (Sapindaceae) Leaves Extracts on Candida Species - Experimental Study

Aims: The aim of this study was to evaluate in vitro the antifungal activity of Dissotis multiflora (Melastomataceae) and Paullinia pinnata (Sapindaceae) leaves extracts on six species of Candida. Study Design: This study was an experimental study. Duration and Place of the Study: Between March to August 2017, Department of Microbiology, Microbiology laboratory, University of Yaoundé I. Bacteriology laboratory, Yaoundé University Teaching Hospital (YUHC). Methodology: The fungal strains were isolated from vaginal swab women at the sampling unit of the YUHC. The identification test blastosis and gallery method allowed to differentiate Candida albicans ATCC37037 to Candida krusei, Candida tropicalis, Candida parapsilosis, Candida haemolinii and Candida lipolytica in the Bacteriology laboratory of the YUHC. C. albicans ATCC 37037 came from the Microbiology laboratory of the University of Yaoundé I. The antifungal activity of extracts was carried out on agar medium using (aromatogram) and microdilution method. The effect of the combination of methanolic fractions were assess by the chessboard method. Results: Phytochemical analysis of gude extracts of D. multiflora and P. pinnata revealed the presence of secondary metabolites such as phenols, tannins, anthraquinones, alkaloids, saponins, steroids and flavonoids in both extracts. In general, all of six fungal strains were susceptible to different extracts and fractions with inhibition diameters ranging from 10.33 mm for methanolic fraction of D. multiflorao C. parapsilosis to 19 mm for the same fraction on C. haemolinii). Both the MICs and the MFCs of actives extracts ranged respectively from 0,78 to 12,5 mg / ml and 1,56 to 25 mg/ml, the majority being fungicidal. The combinations showed significant antifungal activity compared to those of the fractions taken individually, especially with MICs reductions of the order to 75%. Conclusion: The antimicrobial activities of the molecules present in our two extracts could justify their use in traditional medicine in the treatment of candidiasis.
