Premiums-Discounts and Exchange Traded Funds

Closed-end mutual funds present a long-standing puzzle for financial economists because they so commonly trade at substantial discounts to their net asset value (NAV) (or occasionally, premiums), thus violating the “law of one price. ” Open-end funds do not have this problem because their investors are always able to sell or redeem shares at NAV. The growing population of exchange-traded funds (ETFs) fall somewhere in between: most investors acquire or liquidate ETF holdings by trading them in the market, which allows deviations between prices and NAVs. But ETFs may also be redeemed or created by deposit or withdrawal of actual shares, which tends to eliminate long-run differences between market prices and NAVs. Yet apparent differences, sometimes substantial ones, do exist. These may be partly spurious though—for example, if some of the transactions prices used in calculating NAV are stale or subject to bid-ask bounce. This article addresses the issue in the context of an errors-in-variables model, in which different potential sources of pricing errors are modeled explicitly. For some ETFs, the existence of a futures market on the same underlying index provides an additional source of information about true NAV. By contrast, NAVs for international ETFs may be based on prices for stocks in foreign markets that are closed when the ETF is trading in the U.S. Engle and Sarkar show that much of the apparent premium or discount between ETF market prices and NAVs can be explained by measurement errors, and that these are smaller and more quickly reversed for domestic ETFs—especially those with associated futures trading—than for international ETFs.
Beam steering and coordinate system rotation improves accuracy of ultrasonic measurements of tissue displacement vector and lateral displacement

correspondence: chikayoshi Sumi Department of Information and communication Science, Faculty of Science and Technology, Sophia University, 7-1, Kioi-cho, chiyoda-ku, Tokyo 102-8554, Japan Tel +813 3238 3415 Fax +813 3238 3321 email c-sumi@sophia.ac. jp Abstract: With the proper use of beam steering and apodization, a higher resolution lateral echo image is obtained than with conventional imaging. This is achieved by superimposing crossed, steered beams, which is referred to as “lateral modulation” (LM). This type of beamforming achieves almost the same accuracy in lateral displacement measurements as in axial displacement measurements, ie, displacement vector measurements. The steering angle (ASTA) can also be used instead of LM, which uses only beams with a steering angle. In this report, the accuracy of the displacement vectors and lateral displacement measurements for LM and ASTA were evaluated using simulations and agar phantom experiments. The parameters used were direction of a displacement vector, steering angles, and rotation angle for the coordinate system. Changes in the steering angle and rotation angle of the coordinate system permit control of frequencies in the respective directions of the coordinate axes. As shown, when performing a simple ASTA for displacement vector measurement, a spectra frequency division should be performed using a previously developed multidimensional autocorrelation or Doppler method instead of block-matching methods. In this version of ASTA, the combination of nonsteering and rotation of the coordinate system is also effective, because the lateral bandwidth does not decrease. In such a case, transmission of a laterally wide wave will also be effective, particularly for three-dimensional measurement/imaging using a two-dimensional array transducer. ASTA can also be used for accurate lateral displacement measurements. Although a proper beam steering and/or a proper coordinate rotation improves the measurement accuracy achieved with LM and ASTA, all measurement accuracies obtained with ASTA are lower than with LM.
Genuine dissaving and optimal growth

Green accounting theories have shown that negative genuine savings at some point in time imply unsustainability. Consequently, recent studies advocate the use of the genuine savings measure for empirical testing: a negative index implies sustainability be rejected. This criterion is not forward-looking: positive current genuine savings do not rule out ’genuine dissaving’ in the future. This paper derives a one-to-one relationship between the sign of longrun genuine savings and the limiting sustainability condition in the capital-resource model: if the sum of the rates of resource regeneration and augmentation exceeds (falls short of) the discount rate, long-run genuine savings are positive (negative). Testing this limiting condition allows to reveal whether current genuine savings are delivering a false message.
What Technology-Enabled Services Do Air Travelers Value? Investigating the Role of Technology Readiness

An increasing use of technology in service delivery presents challenges for businesses, in particular in relation to how customers perceive specific technology-enabled services (TESs) and which TESs they embrace. This study investigates the influence of technology readiness (TR) on travelers’ perceived importance of various airline TESs. Results reveal three categories of TESs: Established, Network Access, and New. Two dimensions of TR—Optimism and Innovativeness—were significantly associated with the perceived importance of TESs. Respondents who reported higher levels of Optimism rated Established TESs as particularly important. In contrast, respondents high on Innovativeness rated Network Access and New TESs as more important. The association between TR dimensions and perceived importance of TESs was more evident in customers of low-cost carriers than in customers of full-service airlines. This study contributes to the TES and TR literature by explaining why a TES may be more (or less) important to different customers through the association of the TR construct.
Görtler vortices: a backward-in-time approach to the receptivity problem

A quantitative definition of the receptivity of the Görtler instability is given by the Green's functions that external disturbances must be scalarly multiplied by in order to yield the amplitude of the most amplified instability mode, defined sufficiently far downstream of the plate's leading edge. These Green's functions (one for each kind of external disturbance, either coming from the free stream or from the wall) are here displayed for the first time. Calculating such functions from a numerical solution of the instability equations would require repeating the calculation for each of a complete set of different initial and boundary conditions; although numerical simulations of the Görtler instability abound in the literature, such a systematic screening has never been attempted. Here, instead, we calculate the Green's functions directly from a numerical solution of the adjoint of the linearized boundary-layer equations, which exploits the fact that the direct and adjoint parabolic problems have opposite directions of stable time-like evolution. The Green's functions can thus be obtained by marching backward in time at the same computational cost as a single forward-in-time integration of the direct problem. The backward-in-time technique is not limited to the Görtler problem; quantitative receptivity calculations for other types of instability can easily be envisioned.
Universal formula for Hilbert series of minimal nilpotent orbits

We show that the Hilbert series of the projective variety $X=P(O_{min}),$ corresponding to the minimal nilpotent orbit $\mathcal O_{min},$ is universal in the sense of Vogel: it is written uniformly for all simple Lie algebras in terms of Vogel's parameters $\alpha,\beta,\gamma$ and represents a special case of the generalized hypergeometric function ${}_{4}F_{3}. $ A universal formula for the degree of $X$ is then deduced.
An Examination of the Effectiveness of Instruction in which Pre-Service Mathematics Teachers Use Technology to Overcome Student Difficulties

It is seen that students face certain difficulties when learning the concepts and the relationships between them in the mathematics education that aims at enabling students to learn on the highest level. Identifying and eliminating these difficulties, helping students in the learning process and guiding them are among teachers' tasks. Overcoming the difficulties experienced by students is considered one of the contributions of the technological use to the mathematics education. Yet, the efficient use of information and communication technologies in overcoming student difficulties is possible through bringing teachers and pre-service teachers in basic knowledge and skills. To this end, the effectiveness of the instruction in which pre-service teachers benefit from information and communication technologies to overcome the difficulties regarding a given concept was investigated. The participants were 32 third-year pre-service teachers attending at the elementary mathematics education of a state university. The effectiveness of pre-service teachers' micro-instructions and their opinions on the role and effect of technology in their instructions were analyzed within the framework of specified themes. The instructional plans, observation sheets, self-evaluations, and the inventory of the interviews performed in regard to self-evaluations which affected the change in the process were analyzed with the content analysis. Consequently, the findings obtained in the study showed how the pre-service teachers performed effective instructions and revealed the positive change in their perspectives, possible means that technologies can offer to students in the mathematics education, and their positive contributions to their own learning. As for the components and recommendations of this pre-service educational program, it will be effective in the planning of instructional process in future studies. Keywords: student difficulties, technological integration, mathematics education, micro-instruction, pre-service teachers
Prevalence of Anterior Open Bite among Yemeni Adults

Background: Anterior open bites a vertical discrepancy where the upper incisors crowns fail to overlap the lower incisors crown when the mandible brought into the centric occlusion. The aims of this study were to determine the prevalence of anterior open bite in the permanent dentition in a sample of sample of Yemeni adults, 18-25 years old in Sana’a city. Materials and methods: The study was conducted in Sana’a at the faculties of dentistry (Sana’a, Al-Salam, and Science and Technology Universities) to ensure a mixed ethnic sample from all cities in Yemen for a sample of 1585 students (576 male and 1009 female). The overbite was recorded in the dental clinics for the dental students directly in the oral cavity by measuring with metallic rulers the degree of the vertical overlap of the upper incisors to the lower incisors during centric occlusion. The data was processed and analyzed using computer software program “SPSS” (Statistical Package for Social Sciences) version 17. A descriptive statistical analysis was used in this study. Results: The overall prevalence of the anterior open bite in the current study was 4.1%, more frequent among male (8%) than female (1.9%). The normal overbite account was 41.2%, increased overbite reported in 26.75% of the sample, reduced over bite in 22.15%, while edge to edge was recorded in 5.8% of the sample. Conclusion: The prevalence of anterior open bite in Yemeni adults was 4.1%. Males generally showed a higher percentage, 4 times more than female (7.99 in male and 1.88 in female).

After obtaining informed consent, we were able to secure complete interview data from a case series of 84 willing and eligible patients (33.7%). The self-reports by patients about their knowledge of their biopsy proven diagnosis as well as their communication to first-degree relatives were obtained from brief telephone interviews that consisted of eleven questions from semi-structured questionnaires. The interviews were conducted by 1 of 2 female medical assistants certified by American Medical Technologies. The questionnaires contained information on first, the knowledge of patient concerning his or her biopsy proven diagnosis of advanced colorectal polyps, second, the communication of their biopsy proven diagnosis to their first-degree relatives. For each variable, the data were coded and frequencies of the self-reports of their biopsy proven diagnosis of advanced colorectal polyps as well as their communication to their firstdegree relatives were calculated. Of the 84 patients, 39 (46.4%) were men, 45 were women, and their mean age was 66 with a range from 41 to 91 years. Among the 84 patients with biopsy proven advanced colorectal polyps, 10 (11.9%) were unaware that they had undergone removal of a polyp. In addition, 46 patients (54.8%) did not inform their first-degree relatives. Finally, 69 (82.1%) were unaware of the type of polyp removed and, therefore, could not know that they had been diagnosed with advanced colorectal pISSN 1598-9100 • eISSN 2288-1956 https://doi.org/10.5217/ir.2018. 00144 Intest Res 2019;17(2):278-280
The role of technology in value co-creation of maternal healthcare: A service-dominant logic perspective

The need for improved quality of healthcare has led to transforming ways in which healthcare is delivered. The role of information technology (IT) in the transformation is moving towards active participation of patients in healthcare. Active participation of patients in healthcare aligns with the service dominant (S-D) logic in which customers are co-creators of value. Technology has been identified as a key driver for value co-creation however the question of how technology can drive value co-creation in healthcare has not been fully explored. This exploratory study investigates ways in which IT has supported value co-creation in maternal healthcare ecosystem. The study was conducted in Gothenburg Sweden in which mixed research methods were used. Interviews were held with midwife healthcare managers and IT managers, a survey questionnaire was sent out to all midwives in Gothenburg. Results were analyzed using S-D logic value co-creation model. Overall findings show that technology has been used as an operant and operand resource to support value co-creation but mainly for healthcare professionals. Practices are identified on how technology has been used in maternal healthcare. Further investigations on how IT can support pregnant women to actively participate in maternal healthcare especially as an operant resource are suggested.
Measurements of natural deposition ice nuclei in Córdoba, Argentina

Abstract. Ice nucleation in the atmosphere is of practical and fundamental importance since ice crystals influence the release of snow, rain and hail. Suspended aerosols in the atmosphere typically initiate freezing at temperatures below −15 °C; although occasionally freezing occurs at higher temperatures. In this work we describe an experimental device designed to measure the concentration of natural ice nuclei under controlled temperature and supersaturation conditions. The measurements were performed at Cordoba City, for temperatures between −15 °C and −30 °C and the sampled air was supersaturated with respect to ice and subsaturated with respect to liquid water; under these conditions the deposition ice nuclei were quantified. There are few studies reported in the literature regarding measurements of deposition ice nuclei concentration and, to our knowledge, there are no previous laboratory data of this kind of ice nuclei for T
Chickens Subjected to Sequential or Wet Feeding

Broiler chickens have a very fast growth rate and are generally fed ad libitum throughout their rearing period to reveal their full genetic potentials (Toghyani et al. 2011). In such conditions, body fat deposition and incidence of metabolic disorders such as ascites and Sudden Death Syndrome (SDS) may increase (Hocking et al. 2002). Feed restriction has been reported as a viable method to defer early-life fast growth rate in broilers and consequently reduces the incidence of such problems (Ozkan et al. 2006). Different methods of feed restriction are applied in practice such as reduced nutrients intake by means of diet dilution (Camacho Fernandez et al. 2002), appetite suppression (Oyawoye and Krueger, 1990), limiting the time of feed access through skip-a-day or meal feeding procedures (Saffar and Khajali, 2010), or limiting quantity of feed offered daily to the birds (Ocak and Sivri, 2008). Meal feeding is a feed restriction, which birds have daily free access to feed at specific times. Meal feeding has been used and The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: control group (C) where birds had free access to feed throughout the experiment, meal fed groups (MF) where birds were meal fed from 7 to 14 d and subsequently meal fed by the control diet (MFC), meal fed a wet diet (MFW) or subjected to a sequential feeding program (MFS) until day 42. The results showed a statistical reduction of feed intake and increased feed conversion ratio during the meal feeding period (P<0.05). Consequently, meal fed chicks had a depressed body weight at 14 d, which was later, compensated (P<0.05). Following meal feeding, birds in the meal fed a wet diet (MFW) group exhibited the highest body weight, but the sequential fed group had significantly (P<0.05) lower feed intake, body weight and feed conversion ratio (FCR) compared to the other groups. The highest relative weight of small intestine and the lowest abdominal fat pad percentage were observed in the MFS group (P<0.05). Birds' antibody responses to Newcastle, Influenza viruses and sheep red blood cell were not influenced by feeding regimes. It is concluded that feeding a wet diet following meal feeding programs can be effectively used in broiler chicken production.
Conventional 2.0 mm Miniplates versus 3D Miniplate in Mandibular Fracture Fixation

The aim of the present study was to clinically and radiographically compare and evaluate the treatment outcomes using 3D miniplate versus conventional 2.0 mm miniplates in fractures fixation of the anterior mandible. The study enrolled 16 patients with a total of 18 fractures; suffering from anterior mandibular fractures (symphysis and/or parasymphysis) requiring open reduction and internal fixations through an intra-oral approach. Groups I patients were fixed using 3D titanium miniplates and screws. Group II patients were fixed using two 2.0 mm titanium miniplates and screws.Postoperative primary clinical treatment outcome points for comparative evaluation for all patients were fracture stability, the need for additional IMF, the need for minor occlusal adjustments and satisfactory occlusion. Secondary assessment points were infection, wound dehiscence and neurosensory deficit. Radiographic evaluation postoperatively was in terms of reduction adequacy, bone union and condylar positional change measurement. With respect to all the evaluated parameters, statistical analysis showed no statistically significant difference between the two groups in termsof clinical and radiographic treatment outcomes.
Magnetic Properties of ()

We present quantum chemical investigations on magnetic properties of several () nanoparticles. The results of calculations show, that only , and particles display paramagnetic properties while other nanoparticles investigated reveal diamagnetic ones. The reason of the derivative paramagnetizability is discussed here. Calculations reveal that the stability of these compounds increases with the increase of the number of O atoms. The limit when the future increase of oxygen atoms does not change binding energy per atoms remarkably is found. The reason why the O atoms could stabilize the Co nanoparticles and change magnetic properties of them is discussed.
Investigating User responses to Mandatory IT-induced organisational changes: a pre-Implementation Study

Organisational spending on IT-systems is still on the rise, despite research indicating that majority of these IT-systems are not used optimally by employees. This has been attributed to a wide range of responses from IT users, especially in a mandatory use context. In spite of decades of research, the identification of various user responses to IT and the factors that influence these responses remain very important. This study seeks to investigate how users respond to mandated IT-induced organisational changes and what factors influence these responses over time. An interpretive case study approach was adopted, with semi-structured interviews used as the primary data source at a Radio/Television station. Preliminary findings indicate that users respond differently (i.e., opportunity and threat responses) to the proposed mandated IT implementation, and also reveal 3 factors (i.e., management support, user involvement, and social influence) that influence a user’s primary appraisal at the pre-implementation stage. The next phase of this study involves expansion of our interview questions and further in-depth interviews at an additional case site, at both the pre and post-implementation stages of Mandated IT-implementation projects. Upon completion, this research is expected to contribute to the IT use literature by deepening our understanding of different user responses to mandated IT-induced organisational changes and also inform managers involved in IT-implementation projects.
