Undergraduate Students' Perceptions of School Psychology: Findings and Implications

Abstract The present study was an initial exploration of the fund and source(s) of knowledge that undergraduate students possess about school psychology. A total of 622 students completed a five-part inventory that assessed their understanding of various psychology disciplines. The responses given for school psychology and clinical psychology were compared across psychology majors, education majors, and “other” majors. Results indicated that although undergraduate students rated their perceived knowledge of school psychology significantly higher than clinical psychology, the mean ratings for both disciplines were low. Undergraduates utilized different sources of information to learn of clinical and school psychology. Both psychology and education majors assigned low priority to school psychology as a graduate school choice. Further, psychology majors rated clinical psychologists as being more involved in individual therapy, assessment, consultation, and research than school psychologists. The implications of these findings as they pertain to future recruitment strategies are discussed.
Anaplastic astrocytoma with eosinophilic granular cells

A 68‐year‐old man, who had no remarkable past medical history, was referred to a hospital because of disorientation and right‐sided hemiparesis. On magnetic resonance imaging, a contrast‐enhanced tumor in the left frontal lobe with perifocal edema was noted. He underwent left frontal lobectomy. Microscopic examination revealed infiltrative atypical astrocytes showing increased cellularity, distinct nuclear atypia, and many mitotic figures, while microvascular proliferation and necrosis were absent. Thus, the tumor was histologically diagnosed as anaplastic astrocytoma. It was of note that cytoplasmic eosinophilic granules were observed in approximately 25% of neoplastic cells. The granules were positively immunostained with anti‐αB‐crystallin antibody, and the other histochemical and immunohistochemical results also corresponded to Rosenthal fibers. The MIB‐1 labeling index of the highest area of the tumor was 22%, while that of granular cells was 2.1%. An ultrastructural study revealed amorphous electron‐dense structures attached to intermediate filament bundles, compatible with Rosenthal fibers. Such structures are relatively common in oligodendroglial tumors; however, they are extremely rare in astrocytic tumors. Fluorescence in situ hybridization targeted against chromosome 1 failed to demonstrate allelic loss of the short arm. The present case should also be discriminated from granular cell astrocytoma. We review related literature and discuss the significance of granules in gliomas.
On relay selection for decode-and-forward relaying

In this letter, we consider a multi-relay network operating in decode-and-forward mode. We propose a novel relay selection method with a low implementation complexity. Unlike the competing schemes, it requires neither error detection methods at relay nodes nor feedback information at the source. We derive a closed-form symbol error rate (SER) expression for multi-relay network under consideration and demonstrate that the proposed selection method is able to extract the full diversity. Extensive Monte Carlo simulations are also presented to confirm the derived SER expressions and to compare the performance of the proposed scheme with its competitors.
Insulin Resistance: A Proinflammatory State Mediated by Lipid-Induced Signaling Dysfunction and Involved in Atherosclerotic Plaque Instability

The dysregulation of the insulin-glucose axis represents the crucial event in insulin resistance syndrome. Insulin resistance increases atherogenesis and atherosclerotic plaque instability by inducing proinflammatory activities on vascular and immune cells. This condition characterizes several diseases, such as type 2 diabetes, impaired glucose tolerance (IGT), impaired fasting glucose (IFG), obesity, hypertension, dyslipidemia, and other endocrinopathies, but also cancer. Recent studies suggest that the pathophysiology of insulin resistance is closely related to interferences with insulin-mediated intracellular signaling on skeletal muscle cells, hepatocytes, and adipocytes. Strong evidence supports the role of free fatty acids (FFAs) in promoting insulin resistance. The FFA-induced activation of protein kinase C (PKC) delta, inhibitor kappaB kinase (IKK), or c-Jun N-terminal kinase (JNK) modulates insulin-triggered intracellular pathway (classically known as PI3-K-dependent). Therefore, reduction of FFA levels represents a selective target for modulating insulin resistance.
Mobile Application Development for Quran Verse Recognition and Interpretations

Mobile learning or “m-learning” is the process of learning when learners are not at a fixed location or time and can exploit the advantage of learning opportunities using mobile technologies. Nowadays, speech recognition is being used in many mobile applications. Speech recognition helps people to interact with the device as if were they talking to another person. This technology helps people to learn anything using computers by promoting self-study over extended periods of time. The objective of this study is focusing on designing and developing a mobile application for the Arabic recognition of spoken Quranic verses. The application is suitable for Android-based devices. The application is called Say Quran and is available on Google Play Store. Moreover, this paper presents the results of a preliminary experimentation to gather feedback from students regarding the developed application
Anagliptin decreases serum lathosterol level in patients with type 2 diabetes: a pilot study

Objective: The mechanism responsible for the lipid-lowering effect of dipeptidyl peptidase-4 (DPP-4) inhibitors remains unknown in humans. We evaluated the effect of anagliptin on serum lipid profiles, including cholesterol synthesis and absorption markers, in Japanese patients with type 2 diabetes. Methods: Thirty patients with type 2 diabetes (20 – 70 years old, low-density lipoprotein cholesterol (LDL-C) level over 120 mg/dl, and no history of treatment with antidiabetic or antihyperlipidemic drugs) were enrolled. One hundred milligrams of anagliptin were administered twice a day for a month. Results: After treatment of anagliptin, the LDL-C and total cholesterol (TC) levels did not decrease overall, but the TC level decreased significantly in 28 patients whose HbA1c levels decreased. Lathosterol decreased significantly, whereas no changes in campesterol, sitosterol or cholestanol were observed. Conclusion: These results of our study show no significant change in LDL-C, a tendency of decrease in TC and non-high-density lipoprotein cholesterol (non-HDL-C) after treatment of anagliptin for 1 month. Anagliptin therapy decreased the cholesterol synthesis marker lathosterol without changing cholesterol absorption markers.
New "mirror-phase vector control" for sensorless drive of permanent-magnet synchronous motor with pole saliency

This paper proposes a new sensorless vector control method for a salient-pole permanent-magnet synchronous motor (SP-PMSM). The proposed method is directly based on a new principle called "mirror-phase characteristics" and has the following high-performance and attractive features: 1) it can allow 250% rated torque at standstill, under which strong flux saturation usually occurs; 2) it can allow ultralow-speed control (the observed minimum speed ratio to the rated speed under the rated motoring or regenerating load is 1/1800); 3) in spite of the ultralow-speed performance, it can operate up to the rated speed; 4) it accepts instant injection of the rated load even for zero-speed control; 5) it accommodates a load with huge moment of inertia. ; 6) it is insensitive to all motor parameters; 7) it is also insensitive to saturation phenomena of stator flux; and 8) it is so simple that it can be implemented with no additional hardware. The high performance and usefulness of the new "mirror-phase vector control" method are verified through experiments.
Comparison of the efficacy of lamivudine and famciclovir in Asian patients with chronic hepatitis B: Results of 24 weeks of therapy

Lamivudine therapy improves hepatic necro‐inflammatory activity, decreases progression of fibrosis, and suppresses hepatitis B virus (HBV) replication. Famciclovir has also been shown to have some effect in the suppression of HBV replication. The aim of the study was to compare the effect of treatment with lamivudine and famciclovir on serum HBV DNA levels in patients with chronic hepatitis B and to assess safety. A prospective randomised clinical study was carried out on 100 patients with chronic hepatitis B infection (50 patients received lamivudine 100 mg daily and 50 patients received famciclovir 500 mg three times a day for 12 weeks. From the twelfth week onwards, patients were offered lamivudine 100 mg daily up to 48 weeks). Significantly more patients treated by lamivudine than by famciclovir had undetectable HBV DNA levels after 12 weeks of therapy (P < 0.001). The median HBV DNA levels were significantly lower in the lamivudine‐treated patients from the second week of treatment onwards (P < 0.001 for all time points up to 12 weeks). At week 16, 4 weeks after the famciclovir treated patients were put on lamivudine, there was no longer any difference in HBV DNA levels between the two groups of patients. Both treatments were well tolerated and no serious adverse events were reported. It was concluded that in Chinese patients with chronic hepatitis B infection, lamivudine achieved effective suppression of HBV DNA levels within 4 weeks of therapy whereas famciclovir had a significantly weaker action.

Responsive behaviors in good times and in bad

Although self-disclosure is a critical aspect of interactions between intimate partners, having a partner who is responsive to one’s needs after the disclosure is equally important. But what does responsiveness look like? Two observational coding systems for responsive behaviors (Study 1) were created to test the links between one partner’s behaviors and the other partner’s outcomes, on videotaped interactions of 79 U.S. dating couples disclosing positive and negative events with each other (Study 2). These systems were useful across both types of disclosure interactions, providing evidence for the importance of responsive behaviors in different contexts. Responsive behaviors were associated with postinteraction perceptions of responsiveness, which is important for understanding how the behavioral response impacts both the discloser and the relationship.
Antifungal, optical, and mechanical properties of polymethylmethacrylate material incorporated with silanized zinc oxide nanoparticles

Background Fungal infected denture, which is typically composed of polymethylmethacrylate (PMMA), is a common problem for a denture wearer, especially an elderly patient with limited manual dexterity. Therefore, increasing the antifungal effect of denture by incorporating surface modification nanoparticles into the PMMA, while retaining its mechanical properties, is of interest. Aim of the study This study aimed to evaluate antifungal, optical, and mechanical properties of heat-cured PMMA incorporated with different amounts of zinc oxide nanoparticles (ZnOnps) with or without methacryloxypropyltrimethoxysilane modification. Materials and methods Specimens made from heat-cured PMMA containing 1.25, 2.5, and 5% (w/w) nonsilanized (Nosi) or silanized (Si) ZnOnps were evaluated. Specimens without filler served as control. The fungal assay was performed placing a Candida albicans suspension on the PMMA surface for 2 h, then Sabouraud Dextrose Broth was added, and growth after 24 h was determined by counting colony forming units on agar plates. A spectrophotometer was used to measure the color in L* (brightness), a* (red-green), b* (yellow-blue) and opacity of the experimental groups. Flexural strength and flexural modulus were determined using a three-point bending test on universal testing machine after 37°C water storage for 48 h and 1 month. Results The antifungal, optical, and mechanical properties of the PMMA incorporated with ZnOnps changed depending on the amount. With the same amount of ZnOnps, the silanized groups demonstrated a greater reduction in C. albicans compared with the Nosi groups. The color difference (ΔE) and opacity of the Nosi groups were greater compared with the Si groups. The flexural strength of the Si groups, except for the 1.25% group, was significantly greater compared with the Nosi groups. Conclusion PMMA incorporated with Si ZnOnps, particularly with 2.5% Si ZnOnps, had a greater antifungal effect, less color differences, and opacity compared with Nosi ZnOnps, while retaining its mechanical properties.
Threshold crossing of device-based intrathoracic impedance trends identifies relatively increased mortality risk

Aims Threshold crossings of impedance trends detected by implanted devices have been associated with clinically relevant heart failure events, but long-term prognosis of such events has not been demonstrated. The aim of this study is to examine the relationship between alterations in intrathoracic impedance and mortality risk in patients with implantable devices. Methods and results We reviewed remote monitoring data in the de-identified Medtronic CareLink® Discovery Link that captured intrathoracic impedance trends for >6 months. The initial 6 months of the cardiac and impedance trends were used as the observation period to create the patient groups and cross-referenced with the Social Security Death Index for mortality data. In our study cohort of 21 217 patients, 36% experienced impedance threshold crossing within the initial 6 months of monitoring (defined as the ‘early threshold crossing’ group). Patients with early threshold crossings demonstrated an increased risk of age- and gender-adjusted all-cause mortality [hazard ratio (HR) 2.15, 95% confidence interval (CI) 1.95–2.38, P< 0.0001]. Increased mortality risk remained significant when analysed in subgroups of patients without defibrillator shock (HR 2.10, 95% CI 1.90–2.34, P< 0.0001, n= 1621) or within those patients without device-detectable atrial fibrillation (AF) during the initial 6 months of monitoring (HR 2.09, 95% CI 1.86–2.34, P< 0.0001, n= 17 235). Both the number and the duration of early threshold crossings of impedance trends detectable by implanted devices were associated with increased mortality risk. Furthermore, the improvement of altered impedance trends portends more favourable prognosis. Conclusions Threshold crossing of impedance trends detectable by implanted devices is associated with relatively increased mortality risk even after adjusted for demographic, device-detected AF, or defibrillator shocks.
Differential Resistance of Gordonieae Trees to Phytophthora cinnamomi

Trees in the Theaceae tribe Gordonieae are valuable nursery crops, but some of these taxa are known to be highly susceptible to root rot caused by Phytophthora cinnamomi Rands. The objective of this study was to evaluate a collection of Gordonieae taxa for resistance to this pathogen. These taxa included Franklinia alatamaha Bart. Ex Marshall, Gordonia lasianthus (L.) Ellis, Schima wallichii Choisy, S. khasiana Dyer, ·Schimlinia floribunda Ranney & Fantz, and ·Gordlinia grandiflora Ranney & Fantz. Abies fraseri (Pursh) Poir. was also included in the study as a positive control. Container- grown trees were inoculated with three isolates of P. cinnamomi and symptoms were rated over an 84-day period during the summer of 2008. Disease symptom ratings from 1 (healthy) to 4 (dead) were collected twice weekly and area under the disease progress curve (AUDPC) values were calculated. None of the S. khasiana or S. wallichii exhibited any root rot symptoms or mortality, whereas the remaining species showed symptoms of infection at varying levels over time. Symptoms in F. alatamaha and A. fraseri were apparent before other taxa, and mortality for both species reached 100% by the end of the experiment. Comparison of AUDPC values indicated that F. alatamaha was the most susceptible followed by A. fraseri. There was no significant difference in AUDPC among themoreresistanttaxa,includingG.lasianthus,bothSchimaspecies,andtheintergeneric hybrids. Values for AUDPC in the hybrid taxa were similar to their more resistant parental genus, indicating that resistance to P. cinnamomi is a partially dominant trait in these plants. These results further suggest the potential to breed improved hybrids of Gordonieae trees with substantial resistance to P. cinnamomi.
Multi-Document Summarization by Maximizing Informative Content-Words

We show that a simple procedure based on maximizing the number of informative content-words can produce some of the best reported results for multi-document summarization. We first assign a score to each term in the document cluster, using only frequency and position information, and then we find the set of sentences in the document cluster that maximizes the sum of these scores, subject to length constraints. Our overall results are the best reported on the DUC-2004 summarization task for the ROUGE-1 score, and are the best, but not statistically significantly different from the best system in MSE-2005. Our system is also substantially simpler than the previous best system.
BF Eridani: a cataclysmic variable with a massive white dwarf and an evolved secondary

We present high- and medium-resolution spectroscopic observations of the cataclysmic variable BF Eridani (BF Eri) during its low and bright states. The orbital period of this system was found to be 0.270881(3) d. The secondary star is clearly visible in the spectra through the absorption lines of the neutral metals Mg I ,F e I and Ca I. Its spectral type was found to be K3±0.5. A radial velocity study of the secondary yielded a semi-amplitude of K2 = 182.5 ± 0.9 km s −1 . The radial velocity semi-amplitude of the white dwarf was found to be K1 = 74 ± 3k m s −1 from the motion of the wings of the Hα and Hβ emission lines. From these parameters, we have obtained that the secondary in BF Eri is an evolved star with a mass of 0.50‐0.59 M� , whose size is about 30 per cent larger than a zero-age main-sequence single star of the same mass. We also show that BF Eri contains a massive white dwarf (M1 � 1.2 M� ), which allows us to consider the system as a Type Ia supernova progenitor. BF Eri also shows a high γ -velocity (γ =− 94 km s −1 ) and substantial proper motion. With our estimation of the distance to the system (d ≈ 700 ± 200 pc), this corresponds to a space velocity of ∼350 km s −1 with respect to the dynamical local standard of rest. The cumulative effect of repeated nova eruptions with asymmetric envelope ejection might explain the high space velocity of the system. We analyse the outburst behaviour of BF Eri and question the current classification of the system as a dwarf nova. We propose that BF Eri might be an old nova exhibiting ‘stunted’ outbursts.
The genus Smittium (Trichomycetes, Harpellales) in the Iberian Peninsula

A study of larval Diptera (Chironomidae, Culicidae and Simuliidae) from Spain has been carried out to fulfill a catalogue of species of the genus Smittium (Harpellales: Legeriomycetaceae) present within these hosts. Among the reported taxa, eight are new species: Smittium brevisporum, S. bulbosporo-phorus, S. gracilis, S. hecatei, S. heterosporum, S. inex-pectans, S. prostratum and S. pseudodimorphum. We also report six previously described species, which are new for the Iberian Peninsula: S. alpinum, S. dipterorum, S. megazygosporum, S. pusillum, S. typhellum and S. fecundum. Three other species (S. simulii, S. culicis and S. culisetae) previously were reported from Spain. In two of them (S. fecundum and S. culicis), we describe for the first time the presence of zygospores. Some of the included species have been artificially cultured as well as ultrastructurally studied using scanning electron microscopy (SEM), with the purpose of observing the surface of both trichospores and the trichospore collar and the morphology of the trichospore appendage.
Nonlinear switching dynamics in a nanomechanical resonator

The oscillatory response of nonlinear systems exhibits characteristic phenomena such as multistability, discontinuous jumps and hysteresis. These can be utilized in applications leading, e.g., to precise frequency measurement, mixing, memory elements, reduced noise characteristics in an oscillator or signal amplification. Approaching the quantum regime, concepts have been proposed that enable low backaction measurement techniques or facilitate the visualisation of quantum mechanical effects. Here we study the dynamic response of nanoelectromechanical resonators in the nonlinear regime aiming at a more detailed understanding and an exploitation for switching applications. Whereas most previous investigations concentrated on dynamic phenomena arising at the onset of bistability, we present experiments that yield insight into the non-adiabatic evolution of the system while subjected to strong driving pulses and the subsequent relaxation. Modeling the behaviour quantitatively with a Duffing oscillator, we can control switching between its two stable states at high speeds, exceeding recently demonstrated results by 10,000.
Enhanced Cortical Extracellular Levels of Cholecystokinin-Like Material in a Model of Anticipation of Social Defeat in the Rat

The involvement of cholecystokinin (CCK) in the mechanisms of stress and/or anxiety was assessed by in vivomicrodialysis in rats subjected to a social stress paradigm. During the initial 30 min period of each conditioning session, a male Sprague Dawley rat (intruder) was placed in a protective cage inside the cage of a male Tryon Maze Dull rat (resident), allowing unrestricted visual, olfactory, and auditory contacts but precluding close physical contact between them. During the following 15 min period, both the protective cage and the resident were removed (nondefeated intruders) or only the protective cage was removed allowing the resident to attack the intruder (defeated rats). This procedure was repeated once daily for 4 d. On the fifth day, a guide cannula was implanted into the prefrontal cortex of intruders. During a single 30 min test session, performed 4 d later, intruders were subjected to only the 30 min protected confrontation to the resident. Anxiety-like behavior (immobility, ultrasonic vocalizations, and defensive postures), associated with an increase (approximately +100% above baseline) in cortical outflow of CCK-like material (CCKLM), were observed in defeated intruders. Pretreatment with diazepam (5 mg/kg, i.p.), but not buspirone (0.5–2 mg/kg, i.p.), prevented both the anxiety-related behavior and CCKLM overflow. The selective CCK-B receptor antagonist CI-988 (2 mg/kg, i.p.) reduced the anxiety-like behavior without affecting the increase in CCKLM outflow. These data indicate that anticipation of social defeat induces a marked activation of cortical CCKergic neurons associated with anxiety-related behaviors in rats.
