Gay- and Straight-Sounding Auditory Cues Elicit Stereotyping About Teaching Effectiveness

The purpose of this study was to examine the effects of a “gay-sounding” voice on heterosexual music teachers’ perceptions of music teaching effectiveness. Music teachers across the United States (N = 575) listened to two men between the ages of 18 and 25 years old with stereotypically gay and straight voices, respectively, reading a short paragraph. After hearing each speaker in counterbalanced order, participants rated the likelihood of each speaker’s ability to demonstrate top skills and behaviors associated with effective teaching using a 4-point Likert-type scale. Listeners rated the gay voice higher on measures of maintaining high musical standards and organization; they rated the straight voice higher on measures of leadership, classroom management, and maturity. Strategies to combat these stereotypes are discussed.
From Transcription to Tubulogenesis: Insights from the Drosophila Ovary

From Transcription to Tubulogenesis: Insights from the Drosophila Ovary Nathaniel Clement Peters Chair of the Supervisory Committee: Dr. Celeste A. Berg, Professor Department of Genome Sciences During Drosophila melanogaster oogenesis, subsets of the epithelial cells that surround each developing egg chamber undergo morphogenesis to form epithelial tubes, and the lumens of these tubes serve as molds for the dorsal appendage (DA) filaments of the mature eggshell. This process is a simple and tractable system for identifying and characterizing the cellular events and molecular mechanisms required for epithelial tube morphogenesis, or tubulogenesis. The work presented in this dissertation provides insight both into the upstream gene regulatory elements that set the stage and maintain control, and into the downstream molecular effectors that govern cell shape, order, and movement, throughout DA tubulogenesis. In Chapter I, I highlight the fundamental importance of cellular tubes and the intimate relationship between tube morphology and function, explain what we do and do not know about the cellular and molecular mechanisms
Electromechanical properties of Nafion/carbon nanotube composites enhanced by black phosphorus

ABSTRACT Ionic polymer-Carbon nanotube composite (IPCC) actuators based on black phosphorus (BP)-Nafion composite membranes were fabricated. BP-Nafion composite was used as the ionic matrix with functional carbon nanotube as electrodes. BP presents as a promising material owing to its high charge mobility using in energy storage materials. It was used in Nafion composite improving the electromechanical properties of BP-Nafion composite. Significantly the interaction between BP and lithium ion was strong which restricted the back diffusion of cation during action and thus enhanced the deformation of actuator without back-relaxation. In addition, layer crystal structure of BP protected the inter-lamellar liquid from evaporation thus ensured the durability. The result IPCC actuator exhibited improvement actuation with blocking force of 2 wt. % BP-Nafion composite of 33.6 gf g−1 for 30s under an electrical field of 2 V, 2.7 times that of neat Nafion. Actuation behavior under AC field could be repeatedly played hundreds of cycles without obvious decrease of blocking force for BP-Nafion composite-based IPCC. Graphical abstract
The Relationships between Smartphone Addiction of Middle School Students and Smartphone Usage Types, Depression, ADHD, Stress, Interpersonal Problems, and Parenting Attitude

The purpose of this study was to examine the relationships between smartphone addiction of middle school students and smartphone usage types, depression, attention deficit hyperactivity disorder (ADHD), stress, interpersonal problems, and parenting attitude. This study was also performed with the aim of verifying the relationships among depression, ADHD, perceived stress, interpersonal problems, and parenting attitude, which are predictors of smartphone addiction. The subjects of this study were 487 local middle school students (234 males and 253 females). The measurement instruments used were the smartphone addiction scale, depression scale (PHQ-9), ADHD scale (K-ARS), perceived stress scale (PSS), interpersonal problem scale (KIIP-SC), and the parenting attitude scale. This study identified the relationships between the variables with correlation analysis and examined the predictors of smartphone addiction with hierarchical multiple regression analysis. According to the study results, the factors that influenced smartphone addiction were gender, stress, and interpersonal problems. In addition, when the confounding variables of smartphone addiction were controlled to examine the effects of smartphone usage types on smartphone addiction, social media use and music/videos were found to have a positively significant effect on smartphone addiction while study had a negatively significant effect. The order of the usage types with the highest influence on smartphone addiction was enjoying music/videos, social media use, and study. This suggests that selective intervention depending on the main smartphone usage type can be effective.
The Effect of Organizational Culture on Firm Performance With Social Responsibility as Mediating Variable

There is a lack of state-owned enterprises (SOEs) and regional-owned enterprises (ROEs) of Indonesia in reporting their social responsibility activities to the provincial governments. At the same time, corporate social responsibility is a mandatory obligation outlined in the Indonesia law. This study aims to analyze the mediating effect of social responsibility in relationship organizational culture and firm performance of SOEs and ROEs in Central Sulawesi Province, Indonesia. This study is survey research by distributing questionnaires to respondents who are SOEs and ROEs employees. The total sample is 245 respondents. The data are analyzed using path analysis. The result of this study shows that organizational culture does not affect firm performance partially. Another finding shows that SOEs and ROEs' organizational culture affects firm performance if the firm does and reports corporate social responsibility. These results mean that social responsibility plays a vital role in increasing firm performance besides focusing on improving organizational culture.
The role of domestication and maternal effects on seed traits of crop–wild sunflower hybrids (Helianthus annuus)

Hybridisation between crops and their wild relatives may promote the evolution of weeds. Seed germination and dormancy are the earliest life-history traits and are highly influenced by the maternal parent. However, the ecological role of the maternal effect on seed traits in the evolution of crop–wild hybrids has received little attention. In this study, we test the relative importance of maternal and hybridisation effects on seed traits of the first generation of crop–wild sunflower hybrids (Helianthus annuus). Seed germination was tested in two wild populations with contrasting dormancy, two cultivated materials and their reciprocal crosses at four different times after harvest and three different temperatures. Seed germination at each of the four times, after ripening response and secondary dormancy were recorded along with four morphological traits. Additionally, the pericarp anatomy was analysed with light and scanning electron microscopy. We observed strong maternal effects on all seed traits. Seed germination, morphology and pericarp anatomy differed largely between the crop and wild seeds and these traits in the crop–wild hybrids resembled their female parent. Slight but significant hybridisation effects were observed in germination, mainly in seeds produced on wild plants. Crop hybridisation changed seed germination, the after ripening response and secondary dormancy in the crop direction. Morphological and anatomical traits associated with domestication strongly correlated with the observed differences in seed germination and dormancy in crop–wild sunflower hybrids. The large maternal effects along with the evolutionary divergence in seed traits were responsible for the large phenotypic differences observed in crop–wild hybrids with the same genetic composition. Wild-like seed traits of hybrids suggest that there are no barriers to crop gene introgression at the seed level whereas crop-like seed traits could be strongly selected against, conditioning the selection of traits expressed later in the life cycle and in the next generations.
Steroid hormone in serum of male mugil cephalus from lake quaron in relation to ultrastructure of steroidogenic secreting tissue

The grey mullet (Mugil cephalus) is one of the most common fish species in the Mediterranean Sea. Morphological and histological studies on testes of this species indicate six successive maturity stages. The specific changes in serum sex hormone levels were found to occur during the different phases of gonadal development. Concentration of serum steroid hormone in male Mugil cephalus revealed a marked drop in serum steroid (estradiol and testosterone) hormone levels in nearly ripe stage when compared with ripe stage, while the concentration of estradiol, testosterone and progesterone at late stage (ripe stage) of sexual maturity was increased. Histological examination and cyclic change in the testes were revealed of active spermatogenesis with all generations in the early stages of testicular development. Nearly ripe testes showed more active spermatogenesis, nests of spermatocytes and small number of spermatids. While at ripe stage, the seminiferous lobules contained a fair quantity of spermatozoa with little spermatids. Ultra-structural examination showed well differentiated interlobular connective tissues which noticed at early stages. In nearly ripe stage, the fine structure revealed that early spermatids have round shaped vacuolized cells, a spherical nucleus with diffuse chromatin and without mitochondria. At this stage the interlobular connective tissue were hypertrophied, increase in thickness and filled with abnormal fibers. The abnormal shape of interlobular tissue was observed. Ultra-structurally, all the spermatozoa cells were deformed in shape, characterized by small ovoid or spherical nucleus with highly compact chromatin, surrounded by thick tissue appeared with two deformed mitochondria. In the present result, the concentration of steroid hormone in Mugil cephalus in Lake Quaron was highly correlated with the dysfunction of gonadal hormone, maturation of gametes and considered as good sign of infertility and shortage in secretion function of these tissues may be due to unsuitable environmental condition in Lake Quaron needed for spawning of male.
Resolving the status of the families Vesicomyidae and Kelliellidae (Bivalvia: Venerida), with notes on their ecology

The bivalve family Vesicomyidae comprises two subfamilies: Pliocardiinae and Vesicomyinae. The Pliocardiinae include conspicuous mostly largeand medium-sized clams, which live in symbiosis with chemoautotrophic bacteria and often dominate chemosynthetic communities in the deep sea. The Vesicomyinae comprise poorly-studied tiny bivalves, which at first sight differ considerably from their better known, large-sized relatives. Vesicomyines have a worldwide distribution from mid-slope to hadal depths and reach abundances of thousands of specimens in one trawl catch in deep-sea trenches. The genus Vesicomya is morphologically very similar to the genus Kelliella, the type genus of family Kelliellidae. This fact has long caused taxonomic ambiguities and it has been suggested that Vesicomya and Kelliella, as well as their respective nominate families, should be synonymized. In this paper we study the relationship between Vesicomya and Kelliella, for the first time using not only morphological characters but also genetic divergence based on the mitochondrial cytochrome c oxidase subunit I (COI) gene. Our molecular data indicate that the genera Vesicomya and Kelliella are clearly distinct and that Kelliella is distantly related to the Vesicomyidae. Results of morphological analysis support the molecular inferences. We provide further evidence for the relationship of vesicomyines and pliocardiines and propose an evolutionary scenario according to which Vesicomyinae is the less derived group and Pliocardiinae the more derived. We provide the first information on stable carbon and nitrogen isotopic composition of soft tissues of Vesicomya and Kelliella. These data do not suggest involvement of chemosynthetically fixed carbon in the nutrition of either Vesicomya or Kelliella. We revise current usage of these two genera and provide lists of the species of each, with details of their distribution. A new species, Vesicomya alleni, is described on the basis of morphological and molecular characters.
Identification of Quantitative Trait Loci / Genes for Low-stachyose and High-sucrose Content in Soybean Seeds

Sucrose is the most abundant soluble carbohydrate in soybean seed. It affects the quality and taste of soyfoods and also increases the metabolizable energy in animal feed. Thus, breeding for high-sucrose soybean cultivars is driven by the demand for livestock feed and the development of food-grade soybeans. The objective of this study was to identify quantitative trait loci (QTL) for sucrose content using single nucleotide polymorphisms (SNP). An F2-derived mapping population was developed from the cross between a regular sucrose line (V97-3000) and a high-sucrose line (V99-5089). A total of 92 F2:3 lines were genotyped with 5361 SNP markers which covered the 20 soybean chromosomes and, from these, 1720 were polymorphic. Seed samples were collected at F2:3, F2:6, and F2:7 generations, and sucrose analysis was performed by using high performance liquid chromatography. Subsequently, linkage maps were constructed with JoinMap software and composite interval mapping (CIM) was conducted to locate QTLs associated with sucrose content. Two QTLs for seed sucrose content were identified on chromosomes 6 and 10, accounting for 17 and 11% of the phenotypic variation observed for this trait. Their net contribution was 0.57 and 0.56% to sucrose increase, respectively. The sucrose QTL on chromosome 10 is located on a similar genetic region of another QTL previously reported, which suggests that these two QTL may be the same. The other sucrose QTL on chromosome 6 has not been previously reported, which indicates that this is a novel QTL. Molecular markers tightly linked to these QTLs could be used for marker-assisted selection in breeding soybean lines with highsucrose profile.
Validating the relationships: which species of Myotis “nattereri” group (Chiroptera: Vespertilionidae) actually inhabits the Caucasus

Abstract Due to their conservative morphology, the complexity of the taxonomic composition of the Myotis “nattereri” species complex was highly underestimated until recently. In recent studies, the form inhabiting the Caucasus region was allocated to the species Myotis tschuliensis. However, no molecular data was available from its type territory in Turkmenistan. We successfully isolated DNA from two paratypes of M. tschuliensis stored in the Zoological museum of Moscow State University and obtained partial sequences of the mitochondrial gene ND1. The analysis of the DNA showed that the specimens from the Caucasus and Turkmenistan undoubtedly belong to the same genetic lineage. However, morphometric analysis of cranial and dental features showed that the Caucasus and Turkmenistan populations differ from each other approximately to the same extent as M. tschuliensis from M. nattereri. It is possible that there is a still undescribed geographical race in the Caucasus. However, final clarification of the taxonomic status of this population requires more extensive studies, both genetic and morphological.
Adaptive controller design with prescribed performance for switched nonstrict feedback nonlinear systems with actuator failures

This article is concerned with the adaptive output‐feedback control of switched nonstrict feedback nonlinear systems. By introducing a novel error surface, an adaptive control strategy is proposed for the general case where the nonlinear functions and the control gain functions are unknown, and the states are unmeasurable. The considered switched nonlinear system contains unknown actuator failures, which are modeled as both loss of effectiveness and lock‐in‐place. In order to improve the transient performance in the presence of unknown actuator failures, the prescribed performance approach is used. The “explosion of complexity” problem is avoided through using low‐pass filters. The stability of the closed‐loop system under arbitrary switching is shown using Lyapunov stability theory, based on which, the tracking error is shown to converge to a small residual set with the prescribed performance bounds. The advantages of the proposed technique are verified through simulations of two numerical and practical examples.
Prey identification of invasive peacock bass from Telabak Lake Malaysia using DNA barcoding technique

Invasive peacock bass Cichla spp . have recently invaded freshwater habitats across Malaysia. Stomach contents of 135 peacock bass captured from the Telabak Lake of East Coast of Peninsular Malaysia were analysed. The preys were examined using visual identification method and mitochondrial DNA barcoding technique to identify the partial digested and decaying preys in the stomach. The current study identified 7 prey species (6 fishes 43.0% and 1 shrimp 5.1%) belongs to 5 families in fishes’ stomach. The results revealed that peacock bass is highly predator and generalist feeder with an opportunistic feeding behaviour. It is highly important to reduce and monitor the abundance of this species for future survival of native species in the lake.
Positive effect of forest structural diversity on aboveground stand carbon stocks for even-aged Scots pine (Pinus sylvestris L.) stands in the Sarıçiçek Forest, Northern Turkey

ABSTRACT This study examines the relationships between forest structural diversity indices and aboveground stand carbon storage for even-aged and pure Scots pine stands located in the Sarıçiçek Forest, Northern Turkey. In the even-aged Scots pine stands, 293 sample plots were selected to represent various stand conditions such as site quality, age, and stand density. The stand structural diversity, including Shannon’s, improved Shannon, Simpson’s, McIntosh, Margalef, and Berger–Parker indices, was used to correlate the stand carbon storage values. Positive partial correlation coefficients between stand carbon storage and forest structural diversity indices, including the improved Shannon index (r = 0.770), Shannon’s index (r = 0.742), Simpson’s index (r = 0.703), the Berger–Parker index (r = 0.657), the Gini index (r = 0.390), and the Margalef index (r = 0.327), were found at the 0.01 level. These results offer an enhancement of theories concerning positive relationships between stand carbon storage and stand structural diversity for pure and single-species forests. Moreover, regarding biodiversity suitability and stand carbon storage as carbon sinks, the results illustrate that forest stands with higher structural diversity may be preferred when used to mitigate global warming.
Turkish Primary Teacher Candidates’ Conceptual Understandings of Gases

The purpose of this study was to determine Turkish primary teacher candidates’ conceptual understandings of gases. In this study, a survey approach was used. The sample consisted of 240 primary teacher candidates. As the data collection tool, a questionnaire of six questions consisting of three open-ended and three multiple choice was used. The validity and reliability of the questionnaire were provided using the opinions of three field experts and the reliability analysis for multiple-choice ones. The responses to the open-ended questions and the drawings were analyzed descriptively using the predetermined codes and then the categories were formed. The findings showed that primary teacher candidates had some common misunderstandings of gases and their level of understanding of gases is rather low. It is suggested that more attention should be given to developing a correct understanding of the fundamental science concepts in primary teacher training.
Predictors of blended learning deployment in institutions of higher learning: theory of planned behavior perspective

Blended learning (BL) has been increasing in popularity and demand and has developed as a common practice in institutions of higher learning. Therefore, this study develops a model to evaluate the critical predictors that determine students' acceptance and deployment of BL in institutions of higher education based on the theory of planned behavior (TPB). ,The empirical analysis entails data collected from 1,811 responses from an online survey questionnaire from students in Malaysian universities, colleges and polytechnics. Partial least square–structural equation modeling (PLS–SEM) was employed for data analysis. ,The results reveal that the attitude, subjective norm, perceived behavioral control and self-efficacy were found to influence students' intention to accept BL. Moreover, results suggest that the intention of students to accept BL approach is significantly influenced by actual BL deployment. ,Data were collected from students in universities, colleges and polytechnics only. Besides, this research is one of the limited studies that explored BL deployment in a Malaysian perspective. ,Findings from this research not only add scientific evidence to BL literature but also provide a better understanding of the predictors that may motivate or discourage learners to deploy BL in institutions of higher learning. ,Respectively, findings from this study aid students to acquire and apply knowledge on how to effectively improve BL initiatives in learning activities. ,This study is one of the fewer studies that investigate students' behavioral intentions toward BL deployment in Malaysia. Additionally, this study contributes to the understanding of the predictors that influence students' intention to accept and deploy BL in their respective institutions.

Experimental and numerical analysis on the limited ductility of H-shaped concrete cable-stayed bridge tower

Abstract When a cable-stayed bridge is subjected to strong ground motions during an earthquake, the vibration of the tower column is much stronger and more severe in the transverse direction than the longitudinal direction, due to the lateral restriction between the tower and the main girder. To address this issue, the current seismic design of cable-stayed bridge recommends that a larger reinforcement ratio in tower column be used to achieve the target seismic performance (i.e., remaining elastic). This entails an increased number of the piles and the reinforcement volume as well and thus such a design is often not cost-effective. Alternatively, the tower column can be designed to have allowable ductile behaviour for saving costs. Therefore, this study aimed to verify the ductility margin and the allowable ductile performance of the H-shaped concrete tower, by studying its lateral elastic-plastic behaviour and damage mechanism through incremental dynamic analysis, and its limited ductility against the lateral inertial forces based on quasi-static test.
