Objective: To learn the phytochemical screening of terpenoids, flavone and phenols from different extracts ofEuphorbia milii Red flowers. Materials and Methods: Euphorbia milii (Euphorbiaceae) is an ornamental plant plays a role in folk medicine. The Chinese use it as a cure for cancer, and some Brazilians believe that it can cure warts.The flowers were extracted with the three different solvents like petroleumether, ethyl acetate and 70% ethanol &the yield were found to be 21 g, 15 g and 12 g respectively, concentrations of 50 % and 100% ethanol respectively. Results: Two triterpenoids, Taraxerol(1), 28-hydroxyfriedelan-1,3-dione-29-oic acid (2) as well as one flavone, Quercetin 3-O-(2"-O-galloyl)-a-Larabinofuranoside (3) and two phenoilccompounds, 7 7'- dihydroxy, 8, 6'- bicoumarin (4), 9-acetyl-3'4'-dimethoxy dehydroconiferyl-3-alcohol (5) were isolated for the first time from the flowers of Euphorbia milii. The structures of the isolated compounds (1–5) were realized on the basis of the spectral data (IR, 1H and 13C NMR and mass). Conclusion: The obtained compounds of Euphorbia milii flowers are effective pharmaceutical compounds which will serve as a better alternative to chemical based pharmaceuticals.
Stochastic Discounting and the Transmission of Money Supply Shocks

This paper studies the effects of money supply shocks in a general equilibrium model that reproduces a term premium of the magnitude observed in the data. In an environment where financial frictions are the main source of monetary non-neutrality, I find that money supply shocks are less effective at stimulating inflation in recessions than in expansions. In terms of quantitative magnitude, the impact effect on inflation of a money supply shock is about half as large during recessions than during booms. This state dependence is essentially due to the time-variation in stochastic discounting that is needed to match the data. JEL Classification: E31, E44, E58
FACTORS AFFECTING MOOCS CONTINUANCE INTENTION IN MALAYSIA : A PROPOSED CONCEPTUAL FRAMEWORK

MOOC is a new extension of e-learning that allow a massive amount of learners to learn on an open and online learning environment. The effectiveness of MOOCs however, is an open question as the completion rates and the overall use of the system are substantially low. This situation leads to raising the question of the long term usage of the technology. Specifically, this study aims to identify the factors that may contribute to the students’ intention to continue use MOOCs in Malaysia study context. Synthesized on previous literature related to online learning adoption, four factors have been identified to influence students to use MOOCs on a continuous basis such as usefulness, enjoyment, interactivity, and openness.
Synthesis and Catalytic Applications of Non-Metal Doped Mesoporous Titania

Mesoporous titania (mp-TiO2) has drawn tremendous attention for a diverse set of applications due to its high surface area, interfacial structure, and tunable combination of pore size, pore orientation, wall thickness, and pore connectivity. Its pore structure facilitates rapid diffusion of reactants and charge carriers to the photocatalytically active interface of TiO2. However, because the large band gap of TiO2 limits its ability to utilize visible light, non-metal doping has been extensively studied to tune the energy levels of TiO2. While first-principles calculations support the efficacy of this approach, it is challenging to efficiently introduce active non-metal dopants into the lattice of TiO2. This review surveys recent advances in the preparation of mp-TiO2 and their doping with non-metal atoms. Different doping strategies and dopant sources are discussed. Further, co-doping with combinations of non-metal dopants are discussed as strategies to reduce the band gap, improve photogenerated charge separation, and enhance visible light absorption. The improvements resulting from each doping strategy are discussed in light of potential changes in mesoporous architecture, dopant composition and chemical state, extent of band gap reduction, and improvement in photocatalytic activities. Finally, potential applications of non-metal-doped mp-TiO2 are explored in water splitting, CO2 reduction, and environmental remediation with visible light.
Pheromone trapping protocols for the Asian palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae).

Protocols for pheromone-based mass-trapping of the Asian palm weevil, Rhynchophorus ferrugineus (Olivier), are presented. The aggregation pheromone, ferrugineol (4-methyl-5-nonanol) released at 3 mg per 24 h was numerically, but not statistically, superior to lower doses, and this rate is recommended for operational trapping programmes. Trap captures were maximized by placing traps at ground level or 2 m high. Vane traps were superior to bucket traps. Insecticide free traps containing funnels to prevent weevil escape were equally as effective as traps using insecticide to retain weevils. Synergism between ferrugineol and host palm volatiles was demonstrated and necessitates the inclusion of palm material in traps for maximum trapping efficacy. Both the Asian palm weevil and coconut rhinoceros beetle, Oryctes rhinoceros, were captured in the same traps without interference between their respective pheromones. These results have led in part to pheromone-based mass-trapping of the Asian palm weevil throughou.
investment to stock markets : the role of corporate net worth evaluation Working paper

Following recent studies by the Bank of England that the low financial market confidence and low expectations about private sector profits over the next three years has lead to unusually low price-to-book ratios, we incorporate a stock market mechanism in a general equilibrium framework. More specifically, we introduce an endogenous wedge between market and book value of capital, and make investment a function of it in a standard financial accelerator model. The price wedge is driven by an information set containing expectations about the future state of the economy. The result is that the impulse responses to exogenous disturbances are on average two to three times more volatile than in the benchmark financial accelerator model. Moreover, the model improves the matching of firm variables and financial rates to US data compared to the standard financial accelerator model. We also derive a model based quadratic loss function and measure the extent to which monetary policy can feed a bubble by further loosening the credit market frictions that entrepreneurs face. A policy that explicitly targets stock market developments can be shown to improve welfare in terms of minimizing the consumption losses of consumers, even when we account for incomplete information of central bankers regarding the current state of the economy.
Endoscopic lifting of simple supercuspidal representations of SO2n+1 TO GL2n

Abstract:We compute the characters of simple supercuspidal representations of the twisted ${\rm GL}_{2n}(F)$ and ${\rm SO}_{2n+1}(F)$ for a $p$-adic field $F$. Comparing them by the endoscopic character relation, we determine the liftings of simple supercuspidal representations of ${\rm SO}_{2n+1}(F)$ to ${\rm GL}_{2n}(F)$, under the assumption that $p$ is not equal to $2$.
Reversible peptide oligomerization over nanoscale gold surfaces

A selective oligomeric formation of amyloid beta 1-40 (Ab 1-40 ) monomers over a nanogold colloidal surface was investigated. An unfolded Ab 1-40 monomer is considered to construct a dimer or trimer based oligomeric form with its hydrophobic segment placing outward under an acidic condition. Under a basic condition, a conformation of Ab is expected to take a folded monomeric form with its hydrophilic segment folded inward, avoiding the networking with residual colloidal particles. The most probable oligomeric form constructed over a 20 nm gold colloidal surface within a 25 ℃ to 65 ℃ temperature range is a dimer based unit and that over 30 or 40 nm gold colloidal surface below 15 ℃ is concluded to be a trimer based unit. However, selective oligomerization was not successfully reproduced under the rest of the conditions. A dipole-induced dipole interaction must cause a flexible structural change between folded and unfolded forms.
Modeling Fonts in Context: Font Prediction on Web Designs

Web designers often carefully select fonts to fit the context of a web design to make the design look aesthetically pleasing and effective in communication. However, selecting proper fonts for a web design is a tedious and time‐consuming task, as each font has many properties, such as font face, color, and size, resulting in a very large search space. In this paper, we aim to model fonts in context, by studying a novel and challenging problem of predicting fonts that match a given web design. To this end, we propose a novel, multi‐task deep neural network to jointly predict font face, color and size for each text element on a web design, by considering multi‐scale visual features and semantic tags of the web design. To train our model, we have collected a CTXFont dataset, which consists of 1k professional web designs, with labeled font properties. Experiments show that our model outperforms the baseline methods, achieving promising qualitative and quantitative results on the font selection task. We also demonstrate the usefulness of our method in a font selection task via a user study.
The war next door: Peace journalism in US local and distant newspapers’ coverage of Mexico

This study explores the relationship between proximity to a conflict and the tendency to use peace journalism rather than war journalism modes of reporting. In the context of the current drug war occurring in Mexico, articles from both local, border region US newspapers and distant US newspapers were coded according to their usage of war or peace journalism frames. Analyses revealed that local newspapers utilized more peace journalism frames overall, and presented a less pessimistic and negative view of the conflict and parties. Distant newspapers, however, were more likely to showcase complexity of the conflict and many parties and people involved.

Feline panleukopenia virus (FPV) is the prototype of closely related parvoviruses isolated from dogs, mink, raccoons, raccoon dogs, foxes and other canids (Parrish, 1990). They were initially named after the hosts from which they had been isolated. Current taxonomy defines canine parvovirus and feline panleukopenia virus as a single entity (Tattersall, 2006), but in the present guidelines, FPV refers to the parvovirus in cats. Search
Endothelial nitric oxide synthase Gene Polymorphism (G894T) in coronary artery disease in Egyptian patients

Background: Endothelial nitric oxide synthase (eNOS) could be a candidate gene for coronary artery disease (CAD). Objectives: To check for the association of polymorphisms of Endothelial nitric oxide synthase (eNOS) (G894T) gene with the susceptibility and severity of coronary artery disease in Egyptian patients. Subjects: This work included 70patient with coronary artery disease and 62 healthy individuals. The mean age of cases was 60.68± 11.29 years (range: 35.00-94.0 years). They included 36 males and 34 females. Methods: DNA was amplified using PCR-SSP for detection of polymorphisms related to endothelial nitric oxide synthase (G894T) gene. Results: Total cases showed significant frequency of G894T GG (P=0.039, OR=0.476), G894T TT (P=0.001, OR=7. 327). These were considered risk genotypes for disease susceptibility. On the other hand, total cases showed non significant frequency with combined heterozygosity for G894T GT (P= 0.546, OR=0.784). Conclusions: Polymorphisms related to endothelial nitric oxide synthase G894T gene may be considered as genetic markers for coronary artery disease among Egyptian cases.

Evaluation of the Psychometric Properties of the Gap-Overlap Task in 10-Month-Old Infants

Understanding the development of attention is key to understanding cognitive maturation. The gap-overlap task can be administered at all ages and is widely used to study the development of overt visual attention. However, studies using the gap-overlap task report different measures and little is known about the tasks’ psychometric properties, especially in infants. We tested the 1-week test–retest reliability of two frequently used gap-overlap measures of attentional disengagement in 10-month-old infants; the gap effect as measured by the difference between the gap and overlap condition and the gap effect as measured by the difference between the gap and baseline condition. Sixty-seven infants performed the gap-overlap task twice, of which 45 infants had sufficient data quality for further analyses. Test–retest reliability of the overlap-gap gap effect was higher (r = .50) than the baseline-gap gap effect (r = .29). Moreover, the shared variance between overlap and baseline saccadic reaction times was moderate to high across sessions. In light of these results and the methodological challenges and limitations of infant research, we consider the overlap-gap gap effect to be a good measure to study the development of attentional disengagement in infants and suggest the exclusion of the baseline condition in future studies.
“Add Flow to the Fire”: Flow and Hope as a Shield against Burnout of Fire Service Workers

Being related to optimal functioning, the concept of flow is valuable for a variety of tasks and activities that entails human endeavor. Though flow gives the individuals the ability to focus energetically and direct their resources towards their goals, it was not studied in relation to the goal-directed variable of hope to date. The present study aimed to examine flow, hope and burnout in professional firefighters in Greece and to examine the antecedents of flow and hope after a challenging work incident. The Dispositional Flow Scale-2 (DFS-2), the Maslach Burnout Inventory-General Survey (MBI-GS) and the Adult Dispositional Hope Scale (ADHS) were filled in by 180 firefighters in a pre- and post-study design. The results showed that after a fire incident, firemen’s burnout scores increased, whereas hope scores decreased. Flow and hope were positively related to professional efficacy, while stable pathways of the ADHS were associated with increased flow after the fire incident. Significant differences were detected in both flow and hope levels in relation to the participants’ burn out, as well as their age, educational level, and family status. The findings have important practical and research implications in terms of empowering workers at such stressful and demanding professions of high social and public health importance.
Public Debt as a Burden on the Future Generation: A Keynesian Approach

By using an overlapping generations (OLG) model in the context of the production economy, this paper shows that public debt lowers the future generation’s well-being even in the situation of imperfect employment equilibrium. According to the dynamically extended multiplier theory, which has a rigorous microeconomic foundation, the effect of the redemption of public debt is equivalent to that of the balanced-budget multiplier because the redemption increases autonomous spending by old generation while the same amount of tax is levied on the young generation. Thus, the aggregate disposable income remains before the issuance since the value of the balanced-budget multiplier is unity. However, it is evident that real GDP before tax reduction increases; it costs more resources to earn the same disposable income. Therefore, it is unavoidable that the issuance of public debt impairs the welfare of future generation even in a Keynesian framework.
SALL 4 expression is associated with poor outcome in hepatocellular carcinoma

Spalt-like transcriptional factor 4 (SALL4), which is located on chromosome 20q13.12-13.31 and encodes a C2H2 zinc-finger transcription factor, has been identified as a putative stem cell marker. In published studies, SALL4 has been proved to contribute to the development of hepatocellular carcinoma (HCC). To systematically evaluate the clinical and prognostic role of SALL4 in HCC, we performed this meta-analysis. A total of 8 studies containing 290 positive and 1063 negative cases were included in our meta-analysis. The quality assessment of included studies was performed by the Newcastle-Ottawa scale (NOS), with an average NOS score of 7.25. Our data indicated that SALL4 expressing level was not associated with the gender (pooled OR = 0.764, 95% CI = 0.5061.153, P = 0.200, fixed effect), histological differentiation (pooled OR = 0.420, 95% CI = 0.132-1.337, P = 0.142, random effect) and Child-Pugh score (pooled OR = 2.014, 95% CI = 0.848-4.784, P = 0.113, fixed effect) in HCC patients. However, high SALL4 statistically related to hepatitis B virus infection (pooled OR = 2.083, 95% CI = 1.3003.338, P = 0.002, fixed effect) and vascular invasion (pooled OR = 1.685, 95% CI = 1.219-2.328, P = 0.002, fixed effect), which led to a lower 1-year disease free survival (1-year DFS, RR = 1.715, 95% CI = 1.078-2.728, P = 0.023) and 1-year overall survival (1-year OS, RR = 2.495, 95% CI = 1.636-3.805, P = 0.000). These findings suggested that SALL4-immunopositive expression might lead to a poorer patient survival in HCC. SALL4 could be served as an efficient marker for prognostic indicator in HCC, and might be a promising target for future HCC therapies.
Anti-inflammatory activities of enzymatic (alcalase) hydrolysate of a whey protein concentrate

This study was designed to evaluate the anti-inflammatory effects of whey protein hydrolysate (WPH) in mice. Hydrolysis for this experiment was conducted in a pH-stat at 20% degree of hydrolysis. Carrageenan-induced paw edema, peritonitis induced by lipopolysaccharide (LPS) and acetic acid-induced writhing were tested to investigate anti-inflammatory activity. Overall, WPH inhibited carrageenan-induced mice paw edema significantly with doses of 30 mg/kg (p < 0.001), 100 mg/kg (p < 0.01) and 300 mg/kg (p < 0.001) at 3 h post carrageenan. The inhibitory values of edema were 60.34, 39.65 and 68.96%, respectively. After 4 h and an intraperitoneal injection of LPS (100 μg/kg), WPH further inhibited leukocyte recruitment to the peritoneal cavity of mice at a dose of 300 mg/kg (p < 0.05). In a number of the writhing episodes, WPH reduced contortions using a dose of 300 mg/kg. These results indicate that the hydrolysate obtained by treatment with alcalase demonstrated anti-inflammatory activity in the experimental models. All the anti-inflammatory actions obtained were also suggested to be due the presence of glutamine. Key words : Whey protein, proteases, hydrolysate, anti-inflammatory activity, mice.
Integrative taxonomy improves understanding of native beneficial fauna: revision of the Nearctic Peristenus pallipes complex (Hymenoptera: Braconidae) and implications for release of exotic biocontrol agents

The Nearctic Peristenus pallipes complex (Hymenoptera: Braconidae) consists of two species groups that are further divided into nine species, separated largely using ecological rather than morphological differences. The species are re‐examined with an integrative approach using morphometric multivariate ratios, molecular (COI and CytB), and ecological data to test the validity of the nine species. The data support only three valid species [P. dayi Goulet, P. mellipes (Cresson) and P. howardi Shaw] rather than nine. New synonymies include: P. braunae Goulet under P. dayi Goulet 2006 syn.n. ; P. carcamoi Goulet, P. otaniae Goulet and P. pseudopallipes (Loan) under P. mellipes (Cresson) syn.n. , and finally P. broadbenti Goulet 2006 and P. gillespiei Goulet 2006 under P. howardi Shaw 1999 syn.n. In light of these taxonomic revisions, the biology and distributions of the Nearctic P. pallipes complex are updated, resulting in three morphologically variable, widespread, multivoltine species rather than nine largely univoltine species with patchy distributions. The integrative taxonomic approach used here allowed for a more accurate delineation of native fauna and their potential to be competitively displaced by foreign biocontrol agents.
OBSERVING AND ASSESSING CHILDREN’S DIGITAL PLAY IN EARLY CHILDHOOD SETTINGS

In early childhood education children increasingly have access to digital technologies to play on and with. Research often centers on using traditional play theories to understand what is occurring, but some theorists are now using a social-cultural lens to explore digital play in a way that is meaningful for the children and educators involved. In this paper we present a new conceptual framework to understand how children learn to use technologies through play. The framework is called the Digital Play Framework and is informed by the socio-cultural concept of tool mediation (1997) and Hutt’s (1966) ideas about explorative and ludic play. The framework is pedagogically useful because it explains the relationship between technology-as-tool and children’s play-based behaviours. It is important to understand this relationship in early childhood because play is the basis for curriculum provision. With play as the basis for curriculum provision, educators need a way to assess and plan for children’s digital activities. In this paper we illustrate the potential of the Digital Play Framework for achieving this goal.
Microteaching impact on Student Teacher's Performance: A Case Study from Kuwait

The purpose of this study is to determine the impact of micro-teaching technique in delivering the lesson to children whose first language is not English. It involved three first year English language teachers who have been teaching in elementary public schools for one year, a group of student teachers who are in their senior academic year preceding the practicum course, and the author who is senior teacher trainer. Participation in this microteaching study has provided a sense of validation for much of what these student teachers do and how they do it, which has resulted in ongoing critical reflection and peer discussion. Although initially the data shows a giving rise to anxiety among some participants, it has led to greater self-awareness and increased confidence in participants' own ability and expertise, and a endorsement of their teaching style and practice.
