Addressing Misperceptions of Underprepared Students: A Case Study at a Public American University.

This study examines faculty/staff perceptions of underprepared students as well as the experiences of these students in the college setting. Understanding that this crucial population has poor retention, we sought to understand who they were and how the faculty/staff felt about them in an effort to better serve them. While most students surveyed believed their professors wanted them to succeed and were interested in their learning, they also offered insight into areas where faculty could further assist their progress. Faculty/staff revealed both positive and negative feelings about underprepared students, often acknowledging feelings of helplessness when working with them. Through data analysis of surveys from both populations, we identified key areas of focus on which to build a professional development model. By bridging gaps in faculty/staff understanding through a faculty networking approach, we are working together to become more student-ready in addressing student needs wherever they fall, thus promoting student success and retention.
A Simplified Model of Nitrogen Flows from Manure Management

This report describes a model to simulate release processes of trace gases from manure into the atmosphere. This "manure handling model" (MHM) provides a mass-consistent scheme to follow nitrogen and carbon compounds along the typical stages of manure treatment in animal husbandry. In each of the model compartments, which reflect the respective stages, conversion between reactive and unreactive nitrogen or carbon species is possible, as well as the release of gaseous compounds from the reactive species. We use total ammoniacal nitrogen (TAN) as the reactive nitrogen species, and degradable volatile solid (VSd) as the reactive carbon species. Conversion parameters, either derived from specific information, e.g. national data, or as default values, allow assessing transformation rates. As a result, the model generates emission factors for the release of nitrogen components (gaseous NH3, N2O, NOx, N2 and NO3 -- in runoff and the associated N2O emission) and CH4 for use in IIASA's integrated assessment model GAINS. Results of MHM have been compared with the German emission model GAS-EM for dairy cattle on liquid manure to demonstrate that the simplified model is able to reflect complex national information. With identical input parameters, the simplified model reproduces results of the more complex models within 1% difference for the emission of all N components and emission of CH4. MHM was also used with default input (excretion rates, emission coefficients and removal factors) to generate emission factors for all possible combinations of animals and control strategies for all European countries. However, a comparison with current GAINS emission factors reveals substantial differences due to country-specific information that is available in GAINS.
Microwave-assisted synthesis of novel mixed tail rufigallol derivatives

Microwave-assisted syntheses of five new series of rufigallol-based mesogens are reported with branched alkyl chains at the peripheral positions. The chemical structures of these newly synthesised compounds were determined by 1H nuclear magnetic resonance (NMR), 13C NMR, infrared spectroscopy, ultraviolet spectroscopy and elemental analysis. The thermotropic liquid crystalline properties were investigated by polarising optical microscopy (POM), differential scanning calorimetry and X-ray diffractometry. Most of the derivatives were found to be liquid crystalline over a wide temperature range.
Investigation of depression and agoraphobia as psychiatric comorbidity in epileptic patients

SUMMARY Aim: Psychiatric comorbidity in epileptic patients is quite frequent. Our study was designed to investigate depression, anxiety, social phobia, agoraphobia in cases of epilepsy. Materials and Methods: A total of 150 epileptic patients and 70 controls were ran-domly enrolled to study. Beck depression inventory (BDI), Liebowitz social phobia scale (LSPS) and Panic agoraphobia scale (PAS) were applied to groups. Results: The mean age of the patients was 34±10 years, the number of male-female was 56/94, whereas the control group’s mean age was 33±10 years, number of male-female was 29/41. The duration of disease was more than 10 years in 44.7% of pa-tients and 60.67% was treated with monotherapy. In the patient group, BDI was found to be 15.18 ± 12.25 and 10.87 ± 9.06 in the control group (p = 0.0038). There was no statistically significant difference between the groups in terms of LSPS. When the groups were evaluated according to PAS, agoraphobia findings were found in 29.33% of the patients and 24% of the control group (p = 0.002). The rate of agoraphobia was found to be 84% in females in the patient group. Conclusion: Depression, social phobia, and agoraphobia complicate the management of epilepsy as psychiatric comorbidities.
Sorption and Diffusion of BTEX through Thin-Film EVOH

The diffusive properties of thin-layer ethylene vinyl alcohol (EVOH) thin-films often used in vapour barriers and co-extruded geomembranes were studied. Sorption, diffusion and permeation were studied for benzene, toluene, ethylbenzene and xylenes (BTEX) contaminants in dilute aqueous solutions. Films with 32 and 44 mol% EVOH were studied, showing a decrease in permeability with higher EVOH content. Sorption was studied for the EVOH thin-films at room temperature, as well as 30, 40 and 50°C. An increase in sorption of BTEXs was observed at elevated temperatures. Results show that the permeability of these non-polar hydrocarbons decreases with decreasing EVOH content from the 32 mol% thin-film ( P g =15–57 x 10 – 14 m 2 s –1 ), to the 44 mol% thin-film ( P g =3–5 x 10 –14 m 2 s –1 ). When compared with the EVOH inner barrier layer of a co-extruded LLDPE/EVOH geomembrane, the co-extruded geomembrane has the lowest P g (0.7–0.9 x 10 minus;14 m 2 s –1 ). P g values are significantly lower for EVOH thin-films and co-extruded geomembranes when compared with standard LLDPE, HDPE and PVC geomembranes.
Investigating the Health Effects of Exposure to Criteria Pollutants Using AirQ2.2.3 in Shiraz, Iran

ABSTRACTThe quality of air is one of the main environmental issues related to human health. The aim of this study was to evaluate the effects of air pollution on the health of residents in Shiraz, as one of the major cities in Southern Iran, with population of 1500000 people. In this study, AirQ2.2. 3 model developed by the WHO European Centre for Environment and Health was used. Daily concentration of particulate matter less than 10 microns in diameter (PM10), sulfur dioxide, nitrogen dioxide and maximum 8-hour average ozone concentration were used to evaluate the health effects of human exposure to these pollutants. The total number of excess deaths, Cardiovascular Disease (CVD) mortality, mortality from respiratory diseases, hospital admissions for CVD and hospital admissions for respiratory disease (RD) were calculated. In 2012 and 2013, hospital admissions for respiratory disease for the WHO baseline incidence of PM10 were respectively 54.6% and 38.6% of the total hospital admissions for respiratory disease. That was the highest short-term health effects on 1500000 Shirazi residents. The assessments carried out indicated the possibility that CVD mortality can play a major role in mortality due to PM10, SO2 and O3 pollutants. Overall, the results showed that health effects resulting from exposure to pollutants are directly related to their concentration. Therefore, immediate action to prevent pollution and reduce emissions from various sources, such as transport and energy production industries, is required to reduce the concentration of pollutants in Shiraz.

Human planning as optimal information seeking

A critical aspect of human intelligence is our ability to plan, that is, to use a model of the world to simulate, evaluate, and select among hypothetical future actions. However, exhaustive planning is intractable because the number of possible action sequences increases exponentially with the number of steps that one plans ahead. Understanding how people are nevertheless able to solve novel problems when their actions have long-reaching consequences is thus critical to understanding human intelligence. Progress in answering this question has been hampered by two challenges: planning cannot be observed and we do not have a good framework for formalizing the tradeoff between performance and computational cost. In this work, we propose solutions to both challenges, based on the idea that planning can be conceptualized as information seeking. Specifically, we model planning as the selection of information-generating computations and introduce an experimental paradigm in which these computations are externalized as mouse clicks. We find that our participants' behavior is broadly consistent with the optimal information-seeking model. We also uncover systematic deviations that might result from heuristic approximations or additional cognitive constraints that have yet to be uncovered.
Influence of DNA and DNA-PEDOT: PSS on dye sensitized solar cell performance

ABSTRACT The present work shows the results of preparation, characterization, and application of DNA and DNA-PEDOT:PSS coatings as HTM in small dye sensitized solar cells. The samples were analyzed by impedance, UV-Vis and microscopic measurements. The measured ionic conductivities of the DNA membranes were of 2.5×10−5 and 1.6×10−3 S/cm at 25 and 75°C, respectively. The addition of PEDOT:PSS to the samples lowered the conductivities to 10−5 – 10−4 S/cm in the 25 – 75°C temperature range. The samples of DNA-PEDOT:PSS also showed lower transmittance as compared to pure DNA ones, which was due to their blue coloration. The addition of DNA and DNA-PEDOT:PSS as HTM in DSSC promoted a decrease of the device conversion efficiency, explained as due to the change of TiO2-DNA morphology, increase of the device reflectance, and significant changes in device series and shunt resistances.
COMPANY ADVISOR'S VIEW: ATTITUDES AND ABILITIES OF STUDENTS DURING AN INTERNSHIP

The world of work requires prospective workers to have skills according to the needs of the 21st century. Thus, it is important to provide work-based learning to provide work experience and develop student skills. The purpose of this study was to identify students' attitudes and skills during the internship from the point of view of company advisors as mentors and users. The method used is a qualitative method with company advisors as to the data source. Data collection was carried out by structured interviews, where interview questions were built based on the reference indicators used, namely work-based learning and learning innovation skills. The results showed that in general during the apprenticeship students have motivation, discipline, the adaptation of work ethics, responsibility in completing tasks and build good interactions with the institutional environment. From the aspect of student learning skills and innovation, there are still a number of things that need to be improved and trained such as problem-solving, communication, innovation, and creativity. Therefore, some of the skills included in learning innovation skills need to be applied in learning in order to prepare students before entering the workforce.
Rationalization of Physicochemical and Structural Requirement of Some Substituted 5-(Biphenyl-4-ylmethyl)Pyrazole as Angiotensin II Receptor Antagonist: A QSAR Approach

A series of angiotensin II (A II) receptor antagonist of some substituted 5(biphenyl-4-ylmethyl) pyrazole were subjected to QSAR analysis using Hansch and Fujita-Ban model, by using combination of thermodynamic, electronic, spatial descriptor and presence or absence of substituent respectively. Several QSAR model were obtained using stepwise regression analysis. Two models from both the method were selected on the basis of the statistical value that shows good significance with AII antagonistic activity. The best QSAR models further validated by leave one out cross validation method. The studies have help to ascertain the role of different substituent in explaining the observed antagonistic activity of this analogue. From Fujita-Ban model, it is predicted that butane and propane at position 1, COOH at position 4 are essential for activity. Group like CH 2 CF 3 at position 1 and COOH in place of tetrazole at R 3 position contribute negative to the biological activity. In Hansch model it is predicted that molar refractivity at the 1 and 3 position shows positive contribution to the biological activity. Field effect at position 4 also shows positives contribution to the biological activity. Hydrogen donar at position R 3 and field effect at position 1 contributes negatively to the biological activity.
Noninvasive online measurement of particle size and concentration in liquid–particle mixture by estimating equivalent circuit of electrical double layer

ABSTRACT Three electrical elements (i.e., resistance, capacitance, and relaxation frequency) of electrical double layer (EDL) formed around particles have been extracted by a measuring–fitting combination for a novel noninvasive online measurement technique of particle size and concentration in a liquid–particle mixture. The measuring–fitting combination means measuring the impedances with electrical-impedance spectroscopy (EIS) method, and fitting the equivalent circuit with Levenberg–Marquardt method. The liquid–particle mixture in the impedance measurement is made of sodium chloride solution and stainless particles; the equivalent circuit is established corresponding to the contents in the liquid–particle mixture. As a result, the influence of the particle size and concentration on the electrical elements in the EDL which are the resistance, capacitance, and relaxation frequency in the EDL are clarified and discussed. This method is useful for determination of the particle size and concentration in liquid–particle mixture.

Increasing trust in the bank to enhance savings: Experimental evidence from India

Recent evidence highlights the importance of trust in explaining bank account savings. According to economic theory, repeated interactions can play a crucial role in shaping trust. We designed the first field experiment that tests whether increased interactions between clients and bankers influence a client's trust in bankers. We promoted interactions by randomly (i) opening accounts for the unbanked and (ii) making weekly payments on their accounts. At the end of these interventions, we measured trust by playing trust games between clients on the one hand, and their own local banker as well as an anonymous other banker on the other hand. The only intervention that has a signicant impact on the number of interactions is opening a bank account. It also greatly increases trust in the anonymous banker, but not in their own banker. Next, we investigate the importance of trust for account savings. We find a strong positive correlation between the clients' trust in their own banker and savings in the account, but their trust in another banker does not correlate with savings. From the decomposition of trust in its different determinants, we learn that expected trustworthiness matters most in explaining savings, while there is a minor role for social preferences and no role for risk attitudes. We conclude that the personalized client-banker relationships are crucial, but not malleable. Strategies which can deal with the expected trustworthiness - such as providing access to an ATM, or to a denser network of local bankers - might promote bank account savings.

Investigation on the Role of Steel Slag Powder in Blended Cement Based on Quartz Powder as Reference

To clarify the role of steel slag powder in blended cement, steel slag powders with different amounts and particle sizes were mixed into blended cement and the inert quartz powder was selected as the reference. -e influences of steel slag powder with different amounts and particle sizes on the hydration and hardening properties of blended cement were studied from hydration heat, nonevaporable water content, porosity, hydration products, and strength. -e results show that the influence coefficient of nonevaporable water content (ՓWn) of blended cement paste is in an exponential relationship with the amount of steel slag powder. Moreover, at a dosage of 30%,ՓWn of blended cement gradually decreases with the increase of steel slag particle size. Both the early and late compressive strengths of blended cement are in a binomial relationship with the amount of steel slag powder. -e influence coefficient of steel slag powder on the compressive strength of blended cement is negative at the age of 3 days, whereas it is positive at the age of 28 days. -e chemical filling effect of 30% steel slag powder with different particle sizes in the blended cement paste is very small, only 1.13%–5.06%. -e hydration products of blended cement containing steel slag are mainly amorphous C-S-H gels and platy Ca(OH)2, and their density are consistent with the law of their porosity.
Chapter 1:The History of Nitroxide-mediated Polymerization

This chapter traces the early history of nitroxide-mediated polymerization (NMP) during the first ∼15 years. It begins with a short prehistory of observations, made during studies on defining initiation mechanisms using nitroxide radical trapping that can be seen to have inspired the initial experiments. The main part of the chapter is devoted to an account of the discovery of NMP in the early 1980s and research carried out in the period through to 1993, which saw most aspects of the polymerization mechanism defined and the process exploited at CSIRO mainly in the synthesis of acrylic block copolymers. We also provide a brief summary of developments in both the patent and open literature during the period 1993–2000 when the process came to the attention of the wider polymer community mainly for the controlled radical polymerization of styrenics. The end of this period saw the discovery of nitroxides such as SG1 and TIPNO, which provided improved utility and versatility to NMP.
A pr 2 00 8 Long heterochromatic paths in heterochromatic triangle free graphs ∗

In this paper, graphs under consideration are always edge-colored. We consider long heterochromatic paths in heterochromatic triangle free graphs. Two kinds of such graphs are considered, one is complete graphs with Gallai colorings, i.e., heterochromatic triangle free complete graphs; the other is heterochromatic triangle free graphs with k-good colorings, i.e., minimum color degree at least k. For the heterochromatic triangle free graphs Kn, we obtain that for every vertex v ∈ V (Kn), Kn has a heterochromatic v-path of length at least d(v); whereas for the heterochromatic triangle free graphs G we show that if, for any vertex v ∈ V (G), d(v) ≥ k ≥ 6, then G a heterochromatic path of length at least 3k 4 .
Non-Thermal Melting of Tungsten Under Intense Electronic Excitations

Abstract Non-thermal effect caused by ultrafast lasers and swift ions in materials are very intriguing, which is of both scientific interest and technological importance. However, the underlying physics of non-thermal effect on ultrafast process remains unclear and the proposed mechanisms have been controversial. Based on the perturbation approximation under tight-binding theory, the non-thermal effect on tungsten (W) are extensively studied. We demonstrate that the non-thermal effect stemmed from the intense electronic excitations induce dramatic decrease in the melting point of W crystal, as well as non-thermal melting inside the W slab. Our analysis shows that the non-thermal forces are essentially responsible for the drop of melting point of the bulk system. Remarkably, the non-thermal effect combined with surface effect on a W film enhance the ordering of the direction of atomic motion near the surface, preventing melting near the surface area, but leading to non-thermal melting in the interior area of the film. Our work also exhibits a unified relationship between the non-thermal melting and the interatomic forces. This relationship is universal in metals and semiconductors irradiated by ultrafast lasers or swift ions, and has been well established long before.
