The Impact of Stratospheric Ozone Feedbacks on Climate Sensitivity Estimates

A number of climate modeling studies have shown that differences between typical choices for representing ozone can affect climate change projections. Here we investigate potential climate impacts of a specific ozone representation used in simulations of the Hadley Centre Global Environment Model for the Coupled Model Intercomparison Project Phase 5. The method considers ozone changes only in the troposphere and lower stratosphere and prescribes stratospheric ozone elsewhere. For a standard climate sensitivity simulation, we find that this method leads to significantly increased global warming and specific patterns of regional surface warming compared with a fully interactive atmospheric chemistry setup. We explain this mainly by the suppressed part of the stratospheric ozone changes and the associated alteration of the stratospheric water vapor feedback. This combined effect is modulated by simultaneous cirrus cloud changes. We underline the need to understand better how representations of ozone can affect climate modeling results and, in particular, global and regional climate sensitivity estimates.
THE EFFECT OF ACCRUAL EARNINGS, CORPORATE GOVERNANCE, AND FIRM SIZE ON EARNINGS PERSISTENCE OF 100 COMPASS INDEX COMPANIES LISTEDN 2015-2016

This study aims to examine the effect of accrual earnings management, corporate governance proxies through independent commissioners , audit committees , and firm size on earnings persistence. The analytical method used is multiple linear regression using secondary data from 100 compass index companies listed in Indonesia Stock Exchange in 2015 - 2016. Based on the test results found that earnings management affect earnings persistence, while corporate governance is proxied through independent commissioners and audit committee have no effect on earnings persistence. Likewise, firm size does not affect earnings persistence. Companies that make earnings management will have a more persistent earnings compared to companies that do not perform earnings management. This research supports agency theory which explains that earnings management is done by signaling motivation. Keywords : earning management, independent commissioners, audit committees, firm size, earnings persintence
Ethical Dow Jones Indexes and Investment Performance: International Evidence

This study examines the relative importance of the Shariah-Compliant Dow Jones market indexes to capture the dynamic behavior of stock returns at economy and industry levels. The analysis indicates that ethical investment has only an insignificant influence on the performance of stock market returns for both the economy and industry levels. Further, alternative measures of investment performance including the Carhart and Habit Formation models have been used to examine the behavior of the Shariah-Compliant Dow Jones market indexes. The findings suggest a negative market timing ability with both Islamic and conventional indexes. While Islamic indexes are growth focused, conventional indexes are value focused. Further, when investigating the performance of Islamic and conventional Dow Jones indexes during the recent financial crisis, there is evidence supportive of Islamic indexes against conventional ones. For sector groupings, the results indicate that parameter estimates are not consistent, suggesting that Islamic indexes are sector oriented. These results are explained to be a consequence of less diversification in Islamic indexes, leading to higher risk in some sector groupings such as technology and consumption services.
Taxation and Tax policy as government strategy tools for Economic development in Nigeria

Taxation, besides its revenue generation capacity, can also be used as a fiscal policy tool to shape the economy. Considering that the Nigerian tax laws have witnessed significant changes over the period, it becomes imperative to assess the performance of such policies through its effect on the economy. The research therefore examines the various tax incentives currently available in the different tax laws, evaluates how taxation and tax policies have affected the economy of Nigeria and the effectiveness of taxation as a government strategy tool for the Nigerian economic development, using time series data of taxation and economic development of the period 1960 to 2007. From correlation, time series and multivariable regression analyses of relationships among variables, the research found out that taxation and tax policies make positive contributions to economicdevelopment. The Nigerian government is advised to improve the provision of social infrastructures because availability and maintenance of public goods are popular ways tax payers conventionally assess the justification of tax collection by the government.
Flow predisposition in Brazilian rugby athletes

Flow describes a mental state in which people seem to flow when they demonstrate a productive and motivated effort. This study sought to understand the significance that rugby athletes attribute to the flow state, the perception of the phenomena in the sports practice and the implications on performance. For that, 8 male athletes participated in the study, representing the juvenile and senior teams submitted to a semi-structured interview. The results indicated that flow occurs in situations that present balance between personal skills and challenges in sports activity. Success in the game, positive emotions, support/encouragement, recognition and overcoming were aspects that marked the experience elected as special. Making use of psychological strategies, high levels of concentration, feeling prepared for the game and positive emotions were cited as fundamental in achieving flow in the game. On the other hand, some aspects, besides causing harm, interrupted the flow: negative emotions, not perceiving one's self as prepared for the challenge, concentration problems, intragroup difficulties. Negative emotions and the feeling that one is not prepared for the challenge were aspects mentioned only by juvenile athletes. The athletes´ speech showed that although they could not describe the flow, they had already experienced this psychological state.
Size matters: Influence of multiple scattering on CALIPSO light‐extinction profiling in desert dust

We investigate the discrepancies in measurements of light extinction and extinction‐to‐backsatter ratio (lidar ratio) of desert dust with CALIPSO and ground‐based lidar systems. Multiwavelength polarization Raman lidar measurements in the Saharan dust plume performed at Praia, Cape Verde, 15.0°N, 23.5°W, during SAMUM–2 in June 2008 were analyzed and compared to results of nearby CALIPSO overflights. The particle extinction coefficients and thus the optical depth are underestimated in the CALIPSO products by about 30% compared to Raman lidar measurements. A pre‐defined lidar ratio of 40 sr at 532 nm is used for mineral dust in the CALIPSO algorithms in agreement with values of 41 ± 6 sr found from constrained retrievals. However, the ground‐based lidar observations show much larger values of the order of 55 ± 10 sr. The discrepancies can be explained by the influence of multiple scattering which is ignored in the CALIPSO retrievals. Based on recent observations of the size distribution of dust particles from airborne in‐situ observations during SAMUM–1, our model calculations show that the multiple‐scattering‐related underestimation of the extinction coefficient in the CALIPSO lidar signals ranges from 10%–40%. We propose a method to overcome this underestimation.
The Effect of Textual Enhancement Techniques on the Acquisition of Passive Form

This experimental study evaluated the possible effects of textual input- based enhancement on the acquisition of passive form on Iranian pre-intermediate EFL learners. Sixty Iranian EFL learners at the pre-intermediate level of proficiency were randomly assigned into three groups; two experimental group and one comparison group. The first experimental group received passages in which the passive forms were repetitive, the second experimental group received passages in which the passive forms were underlined in different colors. The third group (comparison group) received explicit instruction of passive form with no passage. Repetition group received two texts in each session. The study followed a pre-test /treatment/ post-test design. The result indicated that both textually enhanced input, repetitive and underlined in different colors, have a statistically significant effect on the acquisition of target items than explicit instruction group. Moreover, it can be concluded that repetition can be more beneficial than underlined method of enhancement.
Survey Assessment of Indigenous Knowledge Systems for Seed Storage of Rainforest Spice (Monodora myristica) in Southeastern Nigeria.

The assessment of indigenous knowledge for the storage of Monodora myristica seed for planting was carried out in three states (Abia, Enugu and Akwa-Ibom states) of South eastern agroecology. A structured questionnaire was administered to 150 farmers from two LGAs each and 135 retrieved. Data collected were subjected to descriptive statistics like percentage, mean scores, frequency, bar and pie chart. Collection/gathering of M. myristica is mostly done by men between the ages of 61-70%. Those involved in gathering of M. myristica seeds were married and formally educated people. The study further revealed that traditional method of storage is widely accepted since it promotes seed germination as investigated by 74% of the respondents. Insect pest is one of the problems encountered by the farmers hence 66.7% of the respondents have solicited for government assistance. This problem should therefore be addressed as seed security is essential in ensuring increased use of agro-biodiversity which would in turn expand the options, opportunities and remains available at the rural grassroots level to improve nutrition and health, safeguard the household economic security and enhance sustainable agriculture.
Experimental study of the mechanical characteristics of mortars produced with a binder containing two cow dung ashes

cow dung ash, additional mineral, mechanical characteristics, pozzolanic activity:This study concerns the evaluation of the mechanical characteristics of five mortars produced with a binder containing different proportions of cow dung ash produced in laboratory with objective to its using as additional mineral in the production of mortars. Five other mortars are produced with the same binder containing the same proportions cow dung ash produced traditionally and a standard mortar (control) is also produced with the same binder without any mineral in addition. Some compressive strength tests are carried out on test specimens of mortar (40x40x160 mm3). The compressive strength and chemical characteristic allowed us to estimate and to compare the mechanical characteristics and the pozzolanic activity ratio of both used ashes. The pozzolanic activity ratio of both types of cow dung ash is estimated to 75% and 68% in 28 days. The mechanical characteristics of the mortars containing some cow dung ash produced in laboratory are superior for the greater part to those of the mortars containing some cow dung ash produced traditionally. On the other hand, the medium-term (56 and 90 days) mechanical characteristics of the mortars containing until 15 % of cow dung ash produced in laboratory are equivalent to those of reference mortar.
An Observational Study on Canine-assisted Play Therapy for Children with Autism: Move towards the Phrase of Manualization and Protocol Development

Canine-assisted play therapy (CAPT) is an emerging psychosocial intervention for children with autism spectrum disorder (ASD). The present case studies used quantitative observation of experimenter-designated behavioral outcomes to examine the effectiveness of a planned CAPT intervention. By utilizing a coding system with typical and ASD-specific behavioral categories, the verbal and non-verbal social behaviors of two elementary-aged children with ASD as well as intellectual and language impairments at pre-treatment, during CAPT treatment, at post-treatment and at follow-up are systematically coded and analyzed. This study took the first steps toward making CAPT treatment manuals and research protocol available to a wider audience. Their publication will assist in standardizing the technique for replication in research and in practice.
The comparative effect of concept mapping and vocabulary notebook keeping on Iranian EFL learners’ self-regulation in vocabulary learning

Abstract The important role of vocabulary has long been established in second language acquisition, and many theories have been proposed for vocabulary teaching and learning. The current study aimed to investigate the effects of concept mapping and notebook keeping on self-regulation in vocabulary learning. To this aim, 90 female language learners in three intact classes were selected based on convenience sampling as the participants of the study and were given a pretest and posttest of self-regulation in vocabulary. One of the groups was given concept maps while another group received notebook keeping materials as treatment and the last one served as the control group. The collected data were analyzed through running One-Way ANOVA. The results of the analysis revealed that both concept mapping and notebook keeping significantly enhanced self-regulation in vocabulary learning among Iranian EFL learners. Moreover, no significant difference was found between concept mapping and notebook keeping in terms of their effects on self-regulation in vocabulary acquisition. Based on the findings, EFL teachers may intend to encourage learners to employ concept mapping and notebook keeping techniques not only as effective vocabulary learning strategies but also as vehicles for self-regulation growth in vocabulary acquisition.

The social construction of leadership studies: Representations of rigour and relevance in textbooks

Considerations of rigour and relevance rarely acknowledge students, learning or the textbooks many of the academic community use to frame education. Here we explore the construction of meaning around rigour and relevance in four leadership studies textbooks – the two most globally popular leadership textbooks and two recent additions to the field – to explore how these ideas are represented. We read the four texts narratively for structure, purpose, style and application. We further embed the analysis by considering the cultural positioning of the textbook-as-genre within leadership studies as a field more generally. This exploration of the textbook raises critical questions about rigour, relevance and the relationship constructed between them. From this, we argue for a re-commitment to the genuine ‘text-book’ written to engage students in understanding leadership as a continuing conversation between practices, theories and contexts, rather than as a repository of rigorous and/or relevant content that lays claim to represent an objective science of leadership studies.
The instrumental resolution function of synchrotron radiation powder diffractometers in the presence of focusing optics

The theory developed by Caglioti and co-workers [Caglioti, Paoletti & Ricci (1958). Nucl. Instrum. 3, 223–228; Caglioti, Paoletti & Ricci (1960). Nucl. Instrum. Methods, 9, 195–198; Caglioti & Ricci (1962). Nucl. Instrum. Methods, 15, 155–163] and Sabine [(1987). J. Appl. Cryst. 20, 23–27, 173–178] that provides an analytical description of the instrumental resolution function of single-crystal and powder diffractometers consisting of sequences of collimators and crystals is extended by including the effect of collimating and refocusing mirrors. A simple analytical expression with only two fitting parameters (the beam divergence after reflection by the collimating and the refocusing mirrors) is determined, this expression being applicable to all mirror settings. The new theory is applied to experimental data collected at the Swiss Light Source Materials Science beamline powder diffractometer for three photon energies under extreme mirror bending conditions using the small-linewidth powder sample Na2Ca3Al2F14.
Numerical modeling of the soil structure interaction during sinkholes

Sinkholes are the results of underground cavities failure. Due to the fact that those cavities can be natural (for example caused by the dissolution of rocks by underground water flow ) or man-made (such as mines and quarries), large areas are concerned. The consequences of sinkholes on building and on population are generally dramatic. Therefore, it is necessary to determine the effects of any possible sinkhole on existing and new building or public area. Even though it is obvious that the overall stiffness and weight of the structure influences the size and shape of the soil movement profiles, the main features of this soil-structure interaction phenomenon are not well established. Therefore, the common practice consists in evaluating the soil movements in “greenfield” conditions and then designing a structure capable of withstanding these movements. This approach can lead either to over-estimate or under-estimate the actions applied to the structure. Different cases of study will allow us to highlight the main phenomenon and so to propose different solutions to protect the population and the building from this risk. The aim of this article is to shed some light on this complex soil-structure interaction using a numerical approach. In a first step, a small-scale physic model was developed using cohesive Schneebeli material. Now we are using a discrete element approach with PFC2D software from Itasca. However some limitations imposed by PFC2D such as extensive time of computation due to the great number of particules, lead us to look out for a coupled FLAC2D-PFC2D model. This will allow us to represent the soil far of the cavity by a continuum and the soil near the cavity by an assembly of discrete elements. This reduce dramatically the time needed to compute the model and so allow us to perform more different study with variable parameters. The model will present two layer of soil. The first one, on the top of the cavity, will have a weak cohesion and a low thickness. The second one will be a powder soil on which a structure representing a real building could be placed. The soil response will be observed during the formation of a sinkhole in greenfield versus the tests with a building over it. Different parameters will be used : such as the thickness of the two layers, the dimensions of the cavity and the position of the structure over the cavity.
Topological insulator as an optical modulator for pulsed solid‐state lasers

Topological insulators are states of quantum matter that have narrow topological nontrivial energy gaps and a large third‐order nonlinear optical response. The optical absorption of topological insulators can become saturated under strong excitation. In this work, with Bi2Se3 as an example, it was demonstrated that a topological insulator can modulate the operation of a bulk solid‐state laser by taking advantage of its saturable absorption. The result suggests that topological insulators are potentially attractive as broadband pulsed modulators for the generation of short and ultrashort pulses in bulk solid‐state lasers, in addition to other promising applications in physics and computing.
A study of the use and effectiveness of controls in agile information systems development projects

ABSTRACT This study uses control theory as a lens to examine the use of control in agile information systems development (ISD) projects, specifically within software project teams that use agile methodologies. Traditionally, requirements for ISD projects have been defined at the outset and it has been the role of the project manager to control the project and help the team to achieve their goals. However, the goals of agile ISD projects are flexible and can change frequently, with the consequence that it can be difficult for a project manager to determine the most appropriate and effective type of control to use at each stage of a project. The aim of this research is to: develop a research instrument that will identify the control modes used by project teams in agile ISD projects; conduct a survey to collect data; and develop a framework for assessing the effectiveness of each control mode.
