Moduli Spaces of Higher Spin Klein Surfaces

We study the connected components of the space of higher spin bundles on hyperbolic Klein surfaces. A Klein surface is a generalisation of a Riemann surface to the case of non-orientable surfaces or surfaces with boundary. The category of Klein surfaces is isomorphic to the category of real algebraic curves. An m-spin bundle on a Klein surface is a complex line bundle whose m-th tensor power is the cotangent bundle. The spaces of higher spin bundles on Klein surfaces are important because of their applications in singularity theory and real algebraic geometry, in particular for the study of real forms of Gorenstein quasi-homogeneous surface singularities. In this paper we describe all connected components of the space of higher spin bundles on hyperbolic Klein surfaces in terms of their topological invariants and prove that any connected component is homeomorphic to a quotient of a Euclidean space by a discrete group. We also discuss applications to real forms of Brieskorn-Pham singularities.
Scoundrels or Stars? Theory and Evidence on the Quality of Workers in Online Labor Markets

ABSTRACT: Online labor markets allow rapid recruitment of large numbers of workers for very low pay. Although online workers are often used as research participants, there is little evidence that they are motivated to make costly choices to forgo wealth or leisure that are often central to addressing accounting research questions. Thus, we investigate the validity of using online workers as a proxy for non-experts when accounting research designs use more demanding tasks than these workers typically complete. Three experiments examine the costly choices of online workers relative to student research participants. We find that online workers are at least as willing as students to make costly choices, even at significantly lower wages. We also find that online workers are sensitive to performance-based wages, which are just as effective in inducing high effort as high fixed wages. We discuss implications of our results for conducting accounting research with online workers. Data Availability: Contact the au.
Transgender Resiliency: A Comparison of Transgender and Cisgender Therapy Clients’ Family Functioning and Psychological Symptomology

Existing literature often suggests transgender people face increased vulnerabilities in comparison to cisgender people and poorer mental and physical health outcomes. However, studies are increasingly exploring resilience of transgender people and factors contributing to positive coping. The current study compared transgender to cisgender clients at a University-based couple and family therapy center on self-reported psychological symptomology and family functioning. Transgender individuals did not differ significantly from cisgender individuals on family functioning, however transgender individuals reported significantly fewer symptoms on all twelve subscales of psychological symptomology, despite lower income and lower levels of education. Results suggest transgender individuals may develop unique traits or processes allowing them to more effectively cope with stressors, supporting the presence of resiliency in this population.
Building peace in a divided state of Nigeria: The role of counselling in ensuring unity and national development in the country

There are different crises in Nigeria ranging from ethnic-religious crisis to agitation for resource control/break-up of the country, but the religious crisis especially the recent Boko Haram insurgency has attracted international attention and concern. The fallouts of these crises are threatening the country’s unity and national development. Based on the foregoing, this paper examines the prospect of building peace in Nigeria as a divided state leveraging on the roles of counselling in ensuring unity and national development. The paper adopts a survey research method and the use of self-developed questionnaire for data collection. The finding shows that Nigerians have strong confidence in the efficacy of counselling in solving personal problems and that counselling could ensure National unity and development in Nigeria. Thus, to build a united Nigeria, the paper recommends that counselling clinics should be established across the country for students and politicians and all other citizens of Nigeria. This policy recommendation should also be backed up with enabling law.
Drying Characteristics of Radishes using Far Infrared Ray Dryer

Purpose: The purpose of this study was to establish conditions to dry a radish by examining the drying and quality characteristics depending on the air temperature and velocity of a far infrared conveyor dryer. Methods: A sample of weighing 6 kg was dried until the moisture content reached 15±0.5% (w.b.). Four temperatures (50, 60, 70, and 80°C) and three air velocity levels (0.4, 0.6, and 0.8 m/s) were employed as the drying factors. Results: The drying rate increased with the increase in the temperature and air velocity but decreased with time. However, the drying rate was influenced by temperature rather than velocity. At a temperature 50°C with a air velocity of 0.4 m/s, it took 350 min for the radish to dry which was the longest drying time; 80°C with a air velocity of 0.8m/s, it took 180 min for the radish to dry, which was the shortest drying time. △E (the color difference value) increased with the increase in t emperature and air velocity. The browning and rehydration ratio increased as the temperature rose. Energy consumption decreased with the increased temperature and air velocity. Conclusions: Based on the results of this study, the best drying conditions for the radish were determined to be a temperature of 70°C with an air velocity of 0.8 m/s.
The 'materials balance approach' to pollution: its origin, implications and acceptance

In their seminal paper on "production, consumption and externalities" (AER, 1969), Ayres and Kneese initiated a research program on comprehensive analysis and management of residuals and pollution based on two pillars: the study of the residuals-generating materials flow subject to the mass balance principle and the concept of pervasive (pollution) externality. The present paper aims at (i) recalling the origin of that program, (ii) sheding some light on its principal implications from today's perspective and (iii) giving a tentative assessment on how it has been received by environmental and resource economists over the last decades. It is argued that while the externality approach to pollution gained widespread acceptance, the research community was rather reluctant in following Ayres and Kneese's 'material balance approach'. It is shown that neglecting the mass balance principle may - but need not always - lead to flawed policy advice.
What controls the magnetic geometry of M dwarfs

Context: observations of rapidly rotating M dwarfs show a broad variety of large-scale magnetic fields encompassing dipole-dominated and multipolar geometries. In dynamo models, the relative importance of inertia in the force balance -- quantified by the local Rossby number -- is known to have a strong impact on the magnetic field geometry. Aims: we aim to assess the relevance of the local Rossby number in controlling the large-scale magnetic field geometry of M dwarfs. Methods: we explore the similarities between anelastic dynamo models in spherical shells and observations of active M-dwarfs, focusing on field geometries derived from spectropolarimetric studies. To do so, we construct observation-based quantities aimed to reflect the diagnostic parameters employed in numerical models. Results: the transition between dipole-dominated and multipolar large-scale fields in early to mid M dwarfs is tentatively attributed to a Rossby number threshold. We interpret late M dwarfs magnetism to result from a dynamo bistability occurring at low Rossby number. By analogy with numerical models, we expect different amplitudes of differential rotation on the two dynamo branches.
Simple Small-Size Coupled-Fed Uniplanar PIFA for Penta-Band WWAN Clamshell Mobile Phone

Owing to the rapid development in the mobile communication systems, penta-band operation for WWAN communications has been demanded for many modern mobile phones. In this paper, we present a small-size printed PIFA capable of generating two wide operating bands to cover GSM850/900 and GSM1800/1900/UMTS operations in the clamshell mobile phone. The proposed PIFA has a simple uniplanar structure formed by a single radiating strip coupled-fed by a feeding strip and is easily printed on a small area of 10 × 40 mm 2 only. By applying the proposed PIFA at the hinge of the clamshell mobile phone, whose two ground planes are connected through an extended connecting strip of proper length, both the PIFA and the two ground planes can be efficient radiators. Efficient dipole-like resonant modes (0.5λ and 1.0λ modes) can be excited and fine-adjusted to be at about 900 and 1700 MHz for covering GSM850/900/1800 operations. Also note that the excited 0. 5λ dipole-like resonant mode at about 900 MHz has a dual-resonant behavior caused by the use of the coupling feed, hence resulting in a wide operating band capable of covering GSM850/900 operations. With the excited dipole-like resonant modes contributed by the two ground planes of the clamshell mobile phone, the proposed PIFA is only required to provide a resonant mode for covering GSM1900 and UMTS bands. For this reason, only one short resonant strip for the proposed PIFA is required. This behavior leads to a small printed area of 10 × 40 mm 2 required for the proposed PIFA. Moreover, when the clamshell mobile phone is in the idle condition, the proposed PIFA is still promising to cover WWAN operation with acceptable radiation efficiency. The SAR [1] results in 1 g of head tissue from exposure to the antenna radiation of the studied clamshell mobile phone are also tested, and meet the specification of 1.6 W/kg required for practical applications. Details of the proposed antenna and obtained results are presented and discussed.

An Investigation of Potential Factors Leading to Shoulder Injury in Adolescent Rugby Union Players: A Retrospective Cohort Study

Objectives: To investigate the association between potential factors that may lead to shoulder injury in adolescent male rugby union players. Methods: A self-administered questionnaire consisting of 10 standardised questions was used to investigate the incidence of shoulder injury in adolescent male rugby union players. Participants had previously partaken in a study by Rowland and colleagues in 2014 investigating shoulder range of motion, strength and generalised joint hypermobility. Data from the previous and current study was correlated in order to determine the relationship between the aforementioned variables and shoulder stability. Results: Twenty three (23) participants completed the questionnaire with 9 participants (39%) reporting a shoulder injury. No statistically significant association was found between shoulder injury and generalised joint hypermobility (p=0.32), average shoulder range of motion (p=0.38), body mass index (p=0.60) or hand dominance (p=0.53). A statistically significant association was observed between shoulder injury and shoulder muscle strength (p=0.04). Similarly, a statistically significant association was found between left shoulder flexion strength (p=0.03), right shoulder flexion (p=0.03), left shoulder abduction (p=0.03) and right shoulderinternal rotation at 90 degrees abduction (p=0.008). Conclusions: Reduced strength of the shoulder musculature appears to be associated with an increased risk of sustaining a shoulder injury in adolescent male rugby union players. However, it is inconclusive if overall generalised joint hypermobility along with increased active shoulder ranges of motion are associated withshoulder injury. Further investigations are required to determine if muscle strengthening programs are effective in reducing shoulder injuries.
Treefall Gap Dynamics in a Tropical Rain Forest in Papua New Guinea

Abstract: Treefall gaps play important roles in tropical rain-forest ecology. But studies rely increasingly on models, remote sensing, and a few intensively studied research sites, mostly in the neotropics. We studied the basic parameters of gap dynamics (size, causes, and frequency) of treefall gaps in a lower montane primary forest on the southern flank of the central range of Papua New Guinea. We found 40 treefall gaps formed on 10.4 km of transect sampled annually over 3 yr. Mean proportion of forest under new gaps was 0.015/yr. Mean area of treefall gaps ≤1 yr old was 312 m2, and gap area was positively correlated with diameter of the fallen tree. Mostly only large trees (diameter at breast height [DBH] = 53 cm) fell as snapped (n = 23) or uprooted (n = 17), creating both single (n = 34) and multiple (n = 6) treefall gaps. There was no strong directionality in the bearings of treefalls. This study provides some of the first information on gap dynamics in Papua New Guinea, where such data can be used to inform sustainable forestry harvesting practices.
Wh-Argument / Adjunct Asymmetry in Sentence Processing

This study investigates the processing of complex sentences with wh-phrases trying to point out whether the proposals stating that arguments are processed easier than adjuncts work for wh-phrases in case of Turkish. A wh-argument and a wh-adjunct were used in two eye-tracking experiments with two word orders, and two embedded verb types as the variables. The orders and the type of the embedded verbs were the same in each experiment to provide the wh-phrase type to be the main variable to compare. The general outcome of the study showed that wh-argument was processed more quickly than wh-adjunct supporting the diversification proposed by both formal and experimental approaches in terms of argument adjunct distinction. In a particular condition, in which the subcategorization features of the embedded verb mismatched with the number of arguments, the processing of wh-adjunct was faster than wh-argument. This seems to support a verb-oriented approach in licensing the scrambled wh-phrases.
Soil Carbon-13 Natural Abundance under Native and Managed Vegetation in Brazil

The conversion of native Cerrado vegetation (a mixed C 3 and C 4 vegetation) to Pinus caribaea Morelet plantations (a pure C 3 vegetation) and to Brachiaria decumbens stapf pastures (a pure C 4 vegetation) likely affects the C cycle. We used the natural abundance of 13 C (δ 13 C) in vegetation and soil to: (i) quantity the contributions of C 3 and C 4 plants to the organic matter input into the soil under Cerrado vegetation and (ii) determine the degree of the replacement of original Cerrado-derived C by Pinus plantations and pastures. The mean δ 13 C value of the soils (Anionic Acrustoxes) under Cerrado vegetation ranged from -20.5 to -19.7‰, which was dissimilar to the mass-weighted mean δ 13 C signal of the aboveground biomass (-25.8‰). This was because grasses being C 4 plants contributed 11% to the above round biomass but about 50% of the organic matter input to the soil, which was estimated with a simple mixing model of the C 3 and C 4 13 C signals. After 12 and 20 yr, only 30% of the original organic natter in the topsoil was replaced by new organic matter under pasture or Pinus plantation, respectively. This turnover took place without significantly changing the C storage of the top 2 m of the soil (17-19 kg m -2 ). The C replacement under Pinus affected only the top 0.15 m. Our results demonstrate that the C replacement in soils following land-use change in the Oxisols of this study takes several decades and is considerably slower under Pinus than under pasture.

This research aims to investigate the impact of human resource development, organizational commitment and compensation on employee performance. The study, which was located at Sulut Bank, North Sulawesi, uses explanatory or hypothetical investigations. The samples were 125 respondents from the total of 612 employees at the company. The data collection technique utilizes the proportional area random sampling by means of distributing questionnaires to the respondents. The data were then valued, tabulated and analyzed using double linear regression statistics. The results show that: 1) the human resource development has some impacts on the employee performance, 2) the organizational commitment has some significant impacts on the employee performance, and 3) the compensation also has some significant impacts on the employee performance.
Effects of ZnSO4 Foliar Application on Vegetative Growth and Phenolic and Essential Oil Content of Geranium (Pelargonium odoratissimum L.)

Pelargonium odoratissimum is a perennial evergreen used as a fragrant ornamental plant. Leaves, green branches and fresh flowers contain essential oils, that have been shown to possess antibacterial, antifungal, antiviral, insecticidal and antioxidant properties. In order to study the effect of foliar spray of ZnSO4 (0, 1000, 2000, 3000 and 4000 mg L-1) on vegetative growth and some physiological characteristics of Pelargonium odoratissimum L. plants, a pot experiment was carried out during 2015 at the Research Greenhouse of Azarbaijan Shahid Madani University, Iran. Vegetative growth (plant height, fresh and dry weight) was significantly affected by the application of ZnSO4. Foliar application of ZnSO4 promoted plant height especially at 2000 mg L-1. Chlorophyll a, b, total chlorophyll and carotenoid contents were affected with ZnSO4 treatment as well. The content of essential oil was not significantly influenced with ZnSO4 spray. ZnSO4 application had significant effect on total phenolic and anthocyanins (at 1000 and 2000 mg L-1) and total flavonoids (at 2000 mg L-1) content.
Research in Personnel and Human Resources Management Workplace Flexibility across the Lifespan

As demographic changes impact the workplace, governments, organizations, and workers are looking for ways to sustain optimal working lives at higher ages. Workplace flexibility has been introduced as a potential way workers can have more satisfying working lives until their retirement ages. This chapter presents a critical review of the literature on workplace flexibility across the lifespan. It discusses how flexibility has been conceptualized across different disciplines, and postulates a definition that captures the joint roles of employer and employee in negotiating workplace flexibility that contributes to both employee and organization benefits. Moreover, it reviews how flexibility has been theorized and investigated in relation to older workers. The chapter ends with a future research agenda for advancing understanding of how workplace flexibility may enhance working experiences of older workers, and in particular focuses on the critical investigation of uses of flexibility in relation to older workers.
Antifungal Treatment in the Blood and Marrow Transplant Setting – Perspectives from Clinical Experience

Daniel Couriel (The Sarah Cannon Cancer Center, Nashville, TN, US) reviewed recently published data from the Transplant Associated Infection Surveillance Network (TransNet) of 23 US transplant centres, which showed a 12-month cumulative incidence of invasive fungal infection (IFI) among 15,820 HSCT patients of 3.4%. Although this is relatively low, Couriel pointed out that the infection rate in subsets such as allogeneic transplant patients was over six times higher than in those undergoing autologous transplants (8.1% for mismatched related allogeneic versus 1.2% for autologous HSCT).
Dairy shed wastewater treatment by anaerobic digestion technology

Continued growth and consolidation of the livestock industry such as dairy industry has generated large-quantities and high-strength manure, which has long been identified as a major contributor to diffuse source pollution in Australia. However, conventional dairy shed wastewater treatment practices in Australia such as two pond systems still do not provide sufficient treatment. In addition, relevant laws and regulations in terms of nutrient management plans and manure solids disposal require new waste management approaches. Anaerobic digestion (AD) is an efficient, small footprint, cost effective and sustainable technology that should be applied in Australian dairy farms, and has the potential not only to minimise the environmental impacts but also to maximise resource recovery especially generation of useful renewable bio-fuel (methane) including wastewater reuse. In order to be able to design and operate efficiently anaerobic digestion systems, appropriate mathematical models need to be developed to observe and analyse the anaerobic process dynamics and accordingly optimize anaerobic digestion applications before investment of construction and installation. The present paper critically reviews AD technology in the context of dairy shed wastes and AD modelling. The necessity of AD application on Australian dairy farming is discussed, based on conventional dairy waste management practices and relevant laws and regulations. Also the advantages of AD technology are illustrated by comparing traditional and integrated dairy waste management practices. The unique characteristics of Australian dairy shed wastes, the knowledge gap and future trends of AD technology have been identified. As a result, it is known that AD technology should be extended to Australian dairy farming.
Numerical Simulation of Tin Based Perovskite Solar Cell: Effects of Absorber Parameters and Hole Transport Materials

The organometal perovskite solar cells have shown stupendous development and have reached a power conversion efficiency (PCE) of 22.1%. However, the toxicity of lead in perovskite solar cells is a major challenge towards their incorporation into photovoltaic devices and thus needs to be addressed. Tin perovskite (CH3NH3SnI3) have attracted a lot of attention recently and could be a viable alternative material to replace lead perovskite in thin film solar cells. A detail understanding of effects of each component of a solar cell on its output performance is needed to further develop the technology. In this work, we performed a numerical simulation of a planar heterojunction tin based perovskite solar cell using SCAPS (Solar Cell Capacitance Simulator). Results revealed that thickness and defect density of the absorber material strongly influence the PCE of the device. Various types of hole transporting material (HTM) were compared and analysed to improve the performance of the solar cell. Parameters such as hole mobility and acceptor density of HTM also signified dependence on PCE of the device. These results indicate the possibility to design, fabricate and enhance the performance of tin based perovskite solar cells.
