Prevalence of impacted canine among Yemen population in Sana’a city

Objective: Impacted maxillary and mandibular canine is a frequently encountered clinical problem. The objective of the present study was to determine the prevalence of impacted canine in patients visiting an Orthodontic Clinic in Sana'a city, Yemen. Materials and methods: Patients were examined in order to detect the impacted canines by radiographs. This study comprises data from randomly selected 5287 patients. Panoramic radiographs of 5287 were selected irrespective of sex, caste, nutritional and socio-economic status Angulation and depth of impacted canine were also assessed. Results: Out of 5287 surveyed subjects, 188 patients (3.55%) were determined to have canine impactions of whom 123 female and 65 male (Chi‑square = 18.667, df = 1, P = 0.00001). Of those determined with canine impaction, 168 presents with impacted maxillary canines, 8 presents with the impacted mandibular canine and 12 present with impacted canine in both maxillary and mandibular arch. The difference was statistically significant (Chi‑square = 157.362, df = 1, P = 0.0000). 138 subjects present with unilateral impaction, while the rest of the sample (50 subjects) present with bilateral impaction. Mesioangular impaction was found in 137subjects (68.5 %) and only 3 subjects (1.5 %) demonstrated distoangular impaction. Conclusion: Based on the study results, the canine impaction was reported in (3.55%) of Yemeni population included in the survey. Most of the canine impaction occurs in maxillary arch being more prevalent in female and unilateral in mesioangular direction.
Disclosure of Non-financial Material Sustainability Information: Evidence from Australian Listed Companies in the Materials Sector

The broad objective of this paper is to measure the extent of disclosure of non-financial material sustainability information by Australian companies in the materials sector based on the GRI G4 guidelines. GRI G4 guidelines on economic, environmental, and social performance indicators are used based on 2014 and 2015 data to establish what constitutes non-financial material sustainability information by ASX listed Australian companies in the materials sector. The aggregate non-financial material sustainability disclosure is low for all companies in the materials sector. The findings show that a great degree of variation in sustainability disclosures exists among the listed Australian companies in the materials sector based on GRI G4 guidelines. The pattern of disclosure is similar for small-cap and medium-cap companies and they disclose less non-financial material sustainability information than large-cap companies. The sustainability score increased slightly in 2015 compared to 2014 for all companies and subgroup of companies based on market capitalization in aggregate as well as in economic, environmental, and social categories.

The Effect of Burnout, Work Experience, and Work Motivation on Employee Performance with Emotional Intelligence as Variable Moderation

Performance is an important benchmark in the process of employee development and greatly affects the achievement of the organization as a whole. Performance may decline because of the high burnout. High motivation tends to be a maximum performance as well as work experience also influence performance as related to length of service and level of knowledge. In addition, the performance was also affected by emotional intelligence takes an important role to help people in dealing with problems in life. This study is aimed to determine the effect of burnout, work experience, and motivation to work on performance with emotional intelligence as a moderating variable. The method used is quantitative by collecting data using questionnaires and analyzing by moderated regression analysis (MRA). The sampling technique uses convenience sampling. The results show the accepted hypothesis is burnout affects the performance and motivation affects the performance while the rejected hypothesis is high emotional intelligence will reduce the effect of burnout on performance, high work experience will improve the performance. High emotional intelligence will increase the effect of work experience towards the employee performance, and high emotional intelligence will increase the effect of work motivation towards the employee performance.
A physical model of turbulence cascade via vortex reconnection sequence and avalanche

Viscous anti-parallel vortex reconnection is studied by means of direct numerical simulation for vortex Reynolds numbers $Re$ ($\equiv \unicode[STIX]{x1D6E4}/\unicode[STIX]{x1D708}$, circulation/viscosity) up to 40 000. To suppress the inherent symmetry breaking due to the Kelvin–Helmholtz (planar jet) instability, as prevalent in prior studies, and to better explore the progression of the mechanism details, the simulation is performed by imposing symmetry and using double-precision arithmetic. We show, for the first time, the evidence of vortex reconnection cascade scenario initially proposed by Melander and Hussain (CTR Report, 1988), who suggested that the remnant threads, following the first reconnection, undergo successive reconnections in a cascade. Secondary reconnection (the details distinctly captured and visualized at a lower $Re=9000$) leads to the successive generation of numerous small-scale structures, including vortex rings, hairpin-like vortex packets and vortex tangles. As $Re$ increases, the third and higher generations of reconnection form a turbulent cloud avalanche consisting of a tangle of fine vortices. The energy is rapidly transferred to finer scales during reconnection, and a distinct - 5/3 inertial range is observed for the kinetic energy spectrum, associated with numerous resulting fine-scale bridgelets and thread filaments. In addition, we also discover an inverse cascade at large scales through the accumulation of bridgelets. The separation distance $\unicode[STIX]{x1D6FF}(t)$ before the first reconnection is found to scale as $t^{3/4}$, which is different from the typical 1/2 scaling for classical and quantum vortex filament reconnections. Both peak enstrophy and its production rate grow with $Re$ faster than the power law suggested by Hussain and Duraisamy (Phys. Fluids, vol. 23, 2011, 021701). Our simulations not only reveal the detailed mechanisms of high-$Re$ reconnection, but also shed light on the physics of turbulence cascade and present the reconnection avalanche as a realistic physical model for turbulence cascade.
The Influences of Tropical Volcanic Eruptions with Different Magnitudes on Persistent Droughts over Eastern China

In this study, the influences on persistent droughts over Eastern China from tropical volcanic eruptions with three categories of magnitudes, i.e., 25 Tg, 50 Tg, and 100 Tg, were investigated through three groups of volcanic sensitivity experiments based on the Community Earth System Model (CESM). The results showed that, the 25 Tg tropical volcanic eruptions are too weak to significantly influence the regional precipitation changes over Eastern China, while the 50 Tg tropical volcanic eruptions can strongly intensify droughts and prolong the drought conditions for about five years. Both the extension and intensification of the drought conditions induced by 100 Tg tropical volcanic eruption are the largest among the three sensitivity experiments. These drought conditions are mainly caused by the weakened East Asia Summer Monsoon (EASM), and their extension and intensification depend on the strength of the volcanic eruptions. The intensities of weakened EASMs after volcanic eruptions are associated with the distinct ocean–land thermal contrast after eruptions. The ocean–land thermal contrast is the largest after the 100 Tg tropical volcanic eruptions, while it is much weaker after the 25 Tg volcanic eruptions. The durations of drought extensions are determined by the recovery rates of the West Pacific Subtropical High (WPSH), which are associated with the magnitudes of the volcanic eruptions.
Extensions to Radio Frequency Fingerprinting

Radio frequency fingerprinting, a type of physical layer identification, allows identifying wireless transmitters based on their unique hardware. Every wireless transmitter has slight manufacturing variations and differences due to the layout of components. These are manifested as differences in the signal emitted by the device. A variety of techniques have been proposed for identifying transmitters, at the physical layer, based on these differences. This has been successfully demonstrated on a large variety of transmitters and other devices. However, some situations still pose challenges: Some types of fingerprinting feature are very dependent on the modulated signal, especially features based on the frequency content of a signal. This means that changes in transmitter configuration such as bandwidth or modulation will prevent wireless fingerprinting. Such changes may occur frequently with cognitive radios, and in dynamic spectrum access networks. A method is proposed to transform features to be invariant with respect to changes in transmitter configuration. With the transformed features it is possible to re-identify devices with a high degree of certainty. Next, improving performance with limited data by identifying devices using observations crowdsourced from multiple receivers is examined. Combinations of three types of observations are defined. These are combinations of fingerprinter output, features extracted from multiple signals, and raw observations of multiple signals. Performance is demonstrated, although the best method is dependent on the feature set. Other considerations are considered, including processing power and the amount of data needed. Finally, drift in fingerprinting features caused by changes in temperature is examined. Drift results from gradual changes in the physical layer behavior of transmitters, and can have a substantial negative impact on fingerprinting. Even small changes in temperature are found to cause drift, with the oscillator as the primary source of this drift (and other variation) in the fingerprints used. Various methods are tested to compensate for these changes. It is shown that frequency based features not dependent on the carrier are unaffected by drift, but are not able to distinguish between devices. Several models are examined which can improve performance when drift is present. Extensions to Radio Frequency Fingerprinting
Shy and outgoing preservice teachers and their responses to hypothetical problem behaviors in the classroom

Abstract The present study explored the relations among preservice teacher shyness (shy, average, outgoing) and their responses towards hypothetical children displaying classroom problem behaviours (shy/quiet, exuberant/talkative) in the classroom. Participants were 335 elementary preservice teachers attending a Midwest university in the United States. Preservice teachers completed self-reports of shyness and responded to hypothetical vignettes depicting different classroom behaviours. Among the results, shy preservice teachers reported lower self-efficacy and less tendency to use warm/supportive and social-learning strategies as compared to their more outgoing counterparts. Shy preservice teachers also had lower tendency than average teachers to refer to high-powered strategies when dealing with shy children, but more likely with exuberant children. Results are discussed in terms of the role of personality in teaching.
Is the smart mobile phone transforming university educational reality?

ABSTRACT Smartphones (SMPs) play a vital role in the lives of young people and in the university classroom. There are few studies of the use of SMPs by university students, and the existing knowledge is inconsistent and lacking consensus. This article shows the validity of a theoretical model of the use of SMPs in higher education, in the context of the theory of uses and gratifications, and the knowledge gained from previous studies on the use of SMPs by adolescents. The results suggest the existence of a specific educational function for the use of SMPs in university classrooms. Despite the emergent nature of this function, the educational use of SMPs in higher education presents potential consolidation as a source of gratification and satisfaction of educational needs. Their inclusion in the everyday activity of university classrooms will require considerable effort to adapt the educational system, and the training of students and teaching staff must be improved in order to reduce possible interference in learning the communicative and expressive play functions of SMPs.

FAMILY AND PARTNER RELATIONS: IS IT POSSIBLE TO PREDICT ROMANTIC ATTACHMENT ON THE BASIS OF THE QUALITY OF FAMILY RELATIONS?

The main goal of the study is to investigate the prediction possibilities of the dimensions in partners' attachment on the basis of the quality of individuals' experiences of relations in primary family. The sample of 448 students was tested with the modified version of Brennan's Questionnaire for evaluating partners' attachment – PAB (Kamenov & Jelić 2003) and Family interaction quality scale – KOBI (Vulić - Prtorić 2004). The results shows that dimensions of family functioning can predict only 3% of the variabilities on avoidance dimension in a partner relationship. As far as the possibility of predicting the dimension of anxiety in partner relations is concerned, the results show that 8% of the variabilities can be explained in terms of the differences existing among respondents in regard to the dimensions of the family interaction quality, in which case three predictors establish statistically significant links to the criterion: maternal rejection and acceptance and rejection by father. This can lead to a conclusion that luckily, throughout a life, we have more than one significant other based on whom we evaluate oneself and the world around us and adjust our behaviour.

Prevalence of polycystic ovaries among patients with hirsutism and menstrual abnormalities

Background Polycystic ovaries are considered to be the most frequent cause of hirsutism with its prevalence of 10% of woman of reproductive age group. Polycystic ovarian syndrome (PCOS) reflects multiple potential etiologies and variable clinical presentations Objectives To investigate the prevalence of polycystic ovaries among patients with hirsutism and menstrual abnormalities (oligo- or oligohypomenorrhea) and to correlate presence of hirsutism with BMI, polycystic ovaries, ovarian volume and biochemical markers. Patients and methods All patients who presented with oligo- or oligohypomenorrhea or hirsutism either in outpatient clinic of Obstetrics and Gynecology, Shalamar Hospital or a private laser clinic were enrolled in study. Patients who had hirsutism with normal menstrual cycle were excluded from study. Enrolled patients were categorized into two groups on basis of hirsutism, group 1: oligomenorrhea/oligohypomenorrhea with hirsutism and group 2: oligomenorrhea/oligohypomenorrhea without hirsutism. A detailed clinical history, clinical examination, hormonal profile and abdominopelvic ultrasound were done in all patients. SPSS version 16 was used for statistical analysis. Results Out of 90 patients who enrolled in the study, 10 did not report back, so were excluded from study. Out of 80 patients with menstrual problem, 55 (68.7%) had hirsutism (group 1) and 25 (31.3%) had no hirsutism (group 2). Prevalence of polycystic ovaries was 815% among patients with hirsutism and oligo/oligohypomenorrhea (group 1) as compared to 44% in patients with oligo/oligohypomenorrhea without hirsutism (group 2). Ovarian volume >10ml and BMI were not statistically significant among both groups. Regarding hormonal profile, serum LH/FSH ratio and testosterone levels were significant among patients with hirsutism as compared to without hirsutism. Conclusion Prevalence of polycystic ovaries by morphology, FSH/LH ratio and serum testosterone are significantly present among patients with oligo/oligohypomenorrhea and hirsutism as compared to those with oligo/oligohypomennorhea without hirsutism. However Ovarian volume and BMI are not statistically significant among both groups.
A familial case of pachyonychia congenita

Pachyonychia congenita (PC) comprises a group of rare autosomal genodermatosis caused by mutation in any of the four genes KRT6A, KRT6B, KRT16 or KRT17. Classically, it is subdivided into two major variant types, PC-1 (Jadassohn-Lewandowski syndrome) and PC-2 (Jackson-Lawler syndrome). We hereby report a case of 22-year-old, married woman with progressive thickening and discoloration of all 20 nails, multiple, hyperkeratotic lesions present all over the body with oral lesions since childhood. She had a 2-month-old male baby (the only child) who presented with similar lesions of yellowish discoloration and nail thickening of both nails and foot since birth. She was diagnosed as PC type 1.
Digital-Enabled Last Mile: A Study of Passenger Trips in Rural, Low-density Populated Areas

Public transportation in rural areas is difficult due to low numbers of passengers and diverse needs, also reflected in the last mile problem that points to the distance to access transportation hubs in order to connect with core networks of transportation. In this paper, we study public transportation in rural areas using a digital-enabled, demand-responsive service called Plustur. This service was recently introduced as an effort to increase mobility in underserved rural areas by creating routes ad-hoc to answer to the last mile(s). We study how passengers and drivers understand Plustur, as well as experience the role of passenger. Our findings show that Plustur is viewed as a benefit for autonomy of mobility in rural areas, however is lacking in addressing integration of modes of mobilities, flexibility and spontaneous trips. We contribute with design implications for digital multimodal mobility services.
Plio‐Pleistocene Hemispheric (A)Symmetries in the Northern and Southern Hemisphere Midlatitudes

The transition from the warm, stable climate of the Pliocene to the progressively colder glaciations of the Pleistocene, as well as the climate system's evolving response to stationary orbital forcing over the Pleistocene, beg important questions about fundamental climate processes relevant to understanding the impacts of modern anthropogenic forcing of the Earth's energy budget. Here, we gain insight into the evolution of Plio‐Pleistocene climate by generating an alkenone‐derived, orbitally resolved sea surface temperature (SST) record from Ocean Drilling Program Site 1125 in the southwest Pacific. We compare our data set to midlatitude and equatorial SST records and to the benthic ∂18O signal in order to evaluate similarities and differences in climate response between the hemispheres and across latitudes over the Plio‐Pleistocene. Secular trends indicate first‐order symmetry between the Northern and Southern Hemispheres in the magnitude of mean, glacial, and interglacial cooling. However, the tight coupling that is observed on both secular and orbital timescales between Northern Hemisphere, high latitude, and tropical upwelling climate throughout the last 4 Ma does not extend to Southern Hemisphere climate records as Northern Hemisphere glaciation intensifies in the late Pliocene. The 41‐kyr signal remains weak at Site 1125 across the late Pliocene transition but strengthens in conjunction with a major increase in global climate system sensitivity to obliquity forcing beginning around 1.8 Ma. Our analysis points to regionally varied responses across the late Pliocene transition and the emergence of a global feedback mechanism and strengthened obliquity‐band climate sensitivity just prior to the mid‐Pleistocene transition.
