description: در این پژوهش، ابتدا رابطه بین ویژگی های مختلف شرکتی و سطح افشای اطلاعات که طی 32 پژوهش موجود در ادبیات در بیش از بیست کشور دنیا مشاهده شده است، بررسی شد. سپس رابطه بین ویژگی هایی که در ادبیات مربوطه رابطه آن با سطح افشای اطلاعات به دفعات بررسی و تأیید شده بود، به عنوان عوامل بالقوه تأثیرگذار بر سطح افشای اطلاعات در شرکت های پذیرفته شده در بورس اوراق بهادار تهران با نمره های افشای این شرکت ها آزمون شد. برای آزمون رابطه بین ویژگی های شرکتی، شامل: اندازه شرکت، سن شرکت، اهرم مالی، سودآوری و نقدینگی شرکت با سطح افشا، از اطلاعات 510 سال شرکت برای سال های 1387 تا 1391 استفاده و روابط از طریق رگرسیون چند متغیره آزمون شد. نتایج آزمون فرضیه ها نشان می دهد بر خلاف ادبیات موجود، رابطه معنی داری بین اندازه شرکت، اهرم مالی و سن شرکت با سطح افشای اطلاعات در شرکت های پذیرفته شده در بورس اوراق بهادار تهران وجود ندارد. با این حال، رابطه مستقیم و معنی داری بین سودآوری شرکت و وضعیت نقدینگی آن با سطح افشا مشاهده شد که نشان می دهد وضعیت مساعد سودآوری و نقدینگی شرکت ها، مدیران را به افزایش سطح افشای اطلاعات و شفافیت اطلاعاتی ترغیب می کند تا موقعیت مناسب شرکت را از نظر وضعیت سودآوری و نقدینگی به سرمایه گذاران و سایر افراد برون سازمانی نشان دهند.

description: Convex relaxations of the optimal finger selection algorithm are proposed for a minimum mean square error (MMSE) Rake receiver in an impulse radio ultra-wideband system. First, the optimal finger selection problem is formulated as an integer programming problem with a non-convex objective function. Then, the objective function is approximated by a convex function and the integer programming problem is solved by means of constraint relaxation techniques. The proposed algorithms are suboptimal due to the approximate objective function and the constraint relaxation steps. However, they can be used in conjunction with the conventional finger selection algorithm, which is suboptimal on its own since it ignores the correlation between multipath components, to obtain performances reasonably close to that of the optimal scheme that cannot be implemented in practice due to its complexity. The proposed algorithms leverage convexity of the optimization problem formulations, which is the watershed between `easy' and `difficult' optimization problems.

description: In this paper, a decision support system for ship identification is presented. The system receives as input a silhouette of the vessel to be identified, previously extracted from a side view of the object. This view could have been acquired with imaging sensors operating at different spectral ranges (CCD, FLIR, image intensifier). The input silhouette is preprocessed and compared to those stored in a database, retrieving a small number of potential matches ranked by their similarity to the target silhouette. This set of potential matches is presented to the system operator, who makes the final ship identification. This system makes use of an evolved version of the Curvature Scale Space (CSS) representation. In the proposed approach, it is curvature extrema, instead of zero crossings, that are tracked during silhouette evolution, hence improving robustness and enabling to cope successfully with cases where the standard CCS representation is found to be unstable. Also, the use of local curvature was replaced with the more robust concept of lobe concavity, with significant additional gains in performance. Experimental results on actual operational imagery prove the excellent performance and robustness of the developed method.

description: By observing the fact that moving in a straight line is a common flying behavior of unmanned aerial vehicles (UAVs) in normal applications, e.g., power line inspections, and air patrols along with highway/streets/borders, in this paper we investigate the secrecy outage performance of a UAV system with linear trajectory, where a UAV ($S$) flies in a straight line and transmits its information over the downlink to a legitimate receiver ($D$) on the ground while an eavesdropping UAV ($E$) trying to overhear the information delivery between $S$ and $D$. Meanwhile, some information is delivered to $S$ over the uplink from $D$, such as commanding messages to control $S$'s detecting operations, which can also be eavesdropped by $E$. The locations of $S$, $D$, and $E$ are randomly distributed. We first characterize the statistical characteristics (including cumulative distribution functions and probability density function) of the received signal-to-noise ratio over both downlink and uplink, and then the closed-form analytical expressions for the lower boundary of the secrecy outage probability of both downlink and uplink have also been derived accordingly. Finally, Monte-Carlo simulations are given to testify our proposed analytical models.

Accounting for the horizon

description: Firms have long-term relationships with economic agents such as managers, auditors, and suppliers that can be characterized as sequences of shorter lived agents interacting with a longer lived firm. In this framework, the agent's tenure with the firm becomes the object of investigation. Thus, when the firm starts a multi-period relationship with an agent, what is the role played by beliefs about the duration of the relationship? If the relationship is governed by long-term contracts and if the length of the contract can be chosen ex-ante, and commitment to a certain tenure is possible, is there an optimal ex-ante tenure from the firm's owners' point of view? This dissertation addresses several issues related to an agent's tenure in multi-period models, and is based on three essays. The first essay is on auditing and analyzes how beliefs about auditor tenure impact auditor independence and audit pricing. The second and third essays examine the question of optimal managerial tenure in a multi-period agency model, while at the same time investigating the value of commitment and how different assumptions about commitment impact the solution of the agency problem. One other common theme in the first and third essays is the lack of a "last period", so that, while the firm (the principal) has an infinite horizon and needs to consider a succession of auditors or managers, the agents (auditors or managers) have finite horizons. As a result, an agent's last period is not the last period of the model, the firm continues to exist and operate, and a new agent is hired.

description: Perspective texture synthesis has great significance in many fields like video editing, scene capturing etc., due to its ability to read and control global feature information. In this paper, we present a novel example-based, specifically energy optimization-based algorithm, to synthesize perspective textures. Energy optimization technique is a pixel-based approach, so it is time-consuming. We improve it from two aspects with the purpose of achieving faster synthesis and high quality. Firstly, we change this pixel-based technique by replacing the pixel computation with a little patch. Secondly, we present a novel technique to accelerate searching nearest neighborhoods in energy optimization. Using k- means clustering technique to build a search tree to accelerate the search. Hence, we make use of principal component analysis (PCA) technique to reduce dimensions of input vectors. The high quality results prove that our approach is feasible. Besides, our proposed algorithm needs shorter time relative to other similar methods.

description: This study assesses the effectiveness of remediation activities of Grade 5 pupil’s academic performance in the subject Technology and Livelihood Education (TLE). The study used an experimental pretest-posttest design. We chose two schools in the experiment and each school has a class with 50 pupils each. We assigned one school as the independent group and the other one was the experimental group. The researchers worked with the respective teachers in TLE to determine the level of academic performance of the students. First, we administered a pretest during their first grading period. The results for both schools were not impressive, prompting the researchers to advise remediation activities to the experimental group. We advised the independent group to do the usual learning methods. After the intervention, the researcher performed another set of assessment using the results of the second grading period performance. The researchers used a paired t-test to check for significant differences in the scores of the groups. The study found that there is a significant difference in the scores of the pupils after the remediation intervention. Therefore, the researchers concluded that remediation activities can affect the academic performance of the students.

description: Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling "disadvantaged" production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific "trait" improvements. But these GM products can be installed on Green Revolution varieties where continued dynamic varietal improvement is possible. As a consequence, the Gene Revolution complements the Green Revolution, and because trait incorporation expands area planted to Green Revolution varieties, there is potential for productivity improvement in disadvantaged environments.

description: There is hardly any estimate of the returns to schooling in India based on a national level representative data for the recent period. This paper provides estimates of the returns to education in India by gender, age cohort and location (by rural-urban) for the most recent period 1993/4, and also evaluates the changes in returns over a period of time from 1983-94 using a large national level household survey data. The data show that the returns to education increases up to the secondary level and declines thereafter. There is evidence of substantial gender and rural-urban differences in the returns to schooling. The returns to women's education for the primary and middle levels have declined while those for secondary and college levels have increased during the decade 1983-94.

description: We investigate the superconducting gap function of topological superconductor PbTaSe$_2$. Temperature, magnetic field, and three-dimensional (3D) field-angle dependences of the specific heat prove that the superconductivity of PbTaSe$_2$ is fully-gapped, with two isotropic $s$-wave gaps. The pair-breaking effect is probed by systematically increasing non-magnetic disorders through H$^+$-irradiations. The superconducting transition temperature, $T_{\rm{c}}$, is found to be robust against disorders, which suggests that the pairing should be sign-preserved rather than sign-reversed.

description: We consider the three-boson problem with $δ$-function interactions in one spatial dimension. Three different approaches are used to calculate the phase shifts, which we interpret in the context of the effective range expansion, for the scattering of one free particle a off of a bound pair. We first follow a procedure outlined by McGuire in order to obtain an analytic expression for the desired S-matrix element. This result is then compared to a variational calculation in the adiabatic hyperspherical representation, and to a numerical solution to the momentum space Faddeev equations. We find excellent agreement with the exact phase shifts, and comment on some of the important features in the scattering and bound-state sectors. In particular, we find that the 1+2 scattering length is divergent, marking the presence of a zero-energy resonance which appears as a feature when the pair-wise interactions are short-range. Finally, we consider the introduction of a three-body interaction, and comment on the cutoff dependence of the coupling.

description: Conventional 3D convolutional neural networks (CNNs) are computationally expensive, memory intensive, prone to overfitting, and most importantly, there is a need to improve their feature learning capabilities. To address these issues, we propose spatio-temporal short term Fourier transform (STFT) blocks, a new class of convolutional blocks that can serve as an alternative to the 3D convolutional layer and its variants in 3D CNNs. An STFT block consists of non-trainable convolution layers that capture spatially and/or temporally local Fourier information using a STFT kernel at multiple low frequency points, followed by a set of trainable linear weights for learning channel correlations. The STFT blocks significantly reduce the space-time complexity in 3D CNNs. In general, they use 3.5 to 4.5 times less parameters and 1.5 to 1.8 times less computational costs when compared to the state-of-the-art methods. Furthermore, their feature learning capabilities are significantly better than the conventional 3D convolutional layer and its variants. Our extensive evaluation on seven action recognition datasets, including Something-something v1 and v2, Jester, Diving-48, Kinetics-400, UCF 101, and HMDB 51, demonstrate that STFT blocks based 3D CNNs achieve on par or even better performance compared to the state-of-the-art methods.

Taking as starting point the Yang-Mills field coupled to non dynamical particles carrying chromo-electric charge, and by means of a perturbative scheme, we obtain the first two contributions to the on shell action, which are area-invariants. A geometrical interpretation of these invariants is given.

description: The paper analyzes 141 villages in Matlab, Bangladesh from 1974 to 1996, in which half the villages received from 1977 to 1996 a door-to-door outreach family planning and maternal-child health program. Village and individual data confirm a decline in fertility of about 15 percent in the program villages compared with the control villages by 1982, as others have noted, which persists until 1996. The consequences of the program on a series of long run family welfare outcomes are then estimated in addition to fertility: women's health, earnings and household assets, use of preventive health inputs, and finally the inter-generational effects on the health and schooling of the woman's children. Within two decades many of these indicators of the welfare of women and their children improve significantly in conjunction with the program-induced decline in fertility and child mortality. This suggests social returns to this reproductive health program in rural South Asia have many facets beyond fertility reduction, which do not appear to dissipate over two decades.

description: Student bullying a teacher is a phenomenon given with the least attention and focus since the perpetrators were seen as the academe itself. This descriptive study aims to determine the understanding and behavior of students in a higher education institution towards teacher bullying. The study surveyed 105 conveniently selected respondents from the three (3) different departments of a local community college in Olongapo City who were currently enrolled within the school year of 2017-2018. A draft questionnaire was created and submitted for validity, reliability, and consistency checks from different experts. The data collected were then processed using SPSS 22. The following results were generated: the respondent was a female, 18-20 years of age, first-year level and studying under the College of Business and Accountancy. The respondents moderately understood the idea of teacher bullying by students and their behavior towards teacher bullying by students is slightly inappropriate. Significant findings were found when the variables were grouped according to the year level and the department. There was also a low direct relationship that was observed between the understanding, year level and department. Based on the results, pertinent institutional policies and programs were recommended and suggested.

description: The Enterprise Architecture, Analysis and Project Management (EA2PM) framework developed and proposed in this study enables better evaluation of the ability for enterprise architects, project managers and analysts to share system data using their own domain-specific software tools with a focus on the capability to automatically generate a discrete-event simulation model. EA2PM framework is based on applying a Knowledge Management (KM) construct to establish data and information boundaries, and developing a methodology that allows for high levels of traceability from system architecture's environmental factors through assessment of data and information mediation across domains within a KM system.

An application of the EA2PM is studied using a derived (based on real business) business use-case with user-domain-specific software tools with associated formats under a Department of Defense Enterprise Framework-based common data repository. The framework reveals the feasibility for enterprise architects using Vitech CORE software, analysts using Rockwell Arena software, and project managers using Microsoft Project sharing data and information based on a system architecture repository using their respective software tools according to established business mission and associated collaboration processes.

This study found that it is possible for such collaboration to occur. It also discusses some of the existing gaps that prevent exchange of data and information to become automated under the EA2PM framework construct.

description: The decline of human fertility that occurred in Europe and North America in the nineteenth century, and elsewhere in the twentieth century, remains a topic of debate largely because there is no accepted explanation for the event. Disagreement persists in part because researchers have rarely used the detailed quantitative information necessary to form adequate tests of alternative theories. This paper uses district-level data from Bavaria to study the correlates of the decline of fertility in that German kingdom in the nineteenth century. Bavaria's fertility transition was later and less dramatic than in other parts of Germany. The European Fertility Project, the most influential study of the European fertility transition, used very large units of analysis and unrefined measures of economic and social conditions. This project concluded that the fertility transition reflected the simultaneous adoption of new ideas about contraception, and was not caused by adaptation to changing economic and social circumstances. We use smaller units of analysis, better measures of the possible determinants of fertility, and more appropriate econometric methods to study Bavaria's fertility transition. Our results indicate that the European Fertility Project was right about the role of religion and secularization, but missed an important role for the economic and structural effects stressed by economic historians.
Do I really have a choice? The decision making behaviours of post-16 pupils: a qualitative case study

description: In 1997, Lord Dearing proposed a vision that sought to widen participation in higher education (HE) to include young people who would not normally access a university education, including those from disadvantaged backgrounds, and those with alternative qualifications to the traditional advanced (A’) level. The report acted as catalyst for subsequent government policies, resulting in three decades of changes in the HE sector, including a significant growth in the courses and settings available to potential applicants. The context of the present study is therefore that in which young people appear to have more HE choice than ever before, and one in which a government led information agenda has provided potential applicants with a wealth of information to support them in making informed choices. Nevertheless, despite the range of choices available, the author’s personal experience necessitates a hypothesis proposing that this choice may not be as wide for some young people as it first appears, particularly for those from the most disadvantaged backgrounds, or those with alternative level 3 qualifications. By employing the theoretical lenses of Bourdieu’s social reproduction theory and Elster’s theory of adaptive preference, the study seeks to establish the choice processes from the perspective of the young people involved. In the first phase of the study, questionnaires are distributed to year 12 students in two contrasting settings, in order to ascertain how their level 3 choices were made. Meanwhile, in the second phase, a series of focus group activities is conducted in the same two settings, in order to identify the factors that influence the participants’ university choice, and whether there are any perceived barriers to this choice. The findings indicate that while the participants do not suggest that there are any constraints on their choices, there are certain limitations due to their earlier choices. In some cases, these limitations appear to originate from self-imposed barriers, however these are often a result of parental or school expectation. Furthermore, despite providing the participants with a range of statistical evidence to enable them to compare and contrast HE settings, the results reveal that they are far more likely to base their choice on a best fit, rather than one deemed to be the most expedient.

description: The educators of the 21st century have a great task ahead. In today’s world, the educators are expected to have a great deal of professional and personal qualities, and extraordinary skills. This descriptive-correlational study aimed to determine perceptions of college students on a well-qualified educator. The study included 123 selected college students from different colleges in Central Luzon, Philippines using a convenience sampling technique. As data collection tool, a questionnaire prepared by the researcher team was used. Some of the findings of the study include: (1) the respondents answered agree on the context of professional and personal qualities that a teacher should have; (2) while in terms of the skills exhibited by an educator, it got an answer to Very Satisfactory. We also found significant differences in professional qualities, learning and innovation skills and life and career skills when grouped according to the respondent’s profile. There was low-to-moderate evidence of the relationship that existed between the qualities and skills of an educator. The results further confirmed the relationship through regression analysis and found that communication skills affect the qualities of an educator. Based on the results, we discussed and recommended practical suggestions on professional, personal and skills improvements of an educator.

description: The paper examines effects of agricultural extension on crop yields in Kenya controlling for other determinants of yields, notably the schooling of farmers and agro-ecological characteristics of arable land. The data we use were collected by the Government of Kenya in 1982 and 1990, but the estimation results reported in the paper are based primarily on the 1982 data set. The sample used for estimation contains information about crop production, agricultural extension workers (exogenously supplied to farms), educational attainment of farmers, usage of farm inputs, among others. A quantile regression technique was used to investigate productivity effects of agricultural extension and other farm inputs over the entire conditional distribution of farm yield residuals. We find that productivity effect of agricultural extension is highest at the extreme ends of distribution of yield residuals. Complementarity of unobserved farmer ability with extension service at higher yield residuals and the diminishing returns to the extension input, which are uncompensated for by ability at the lower tail of the distribution, are hypothesized to account for this U-shaped pattern of the productivity effect of extension across yield quantiles. This finding suggests that for a given level of extension input, unobserved factors such as farm management abilities affect crop yields differently. Effects of schooling on farm yields are positive but statistically insignificant. Other determinants of farm yields that we analyze include labour input, farmer experience, agro-ecological characteristics of farms, fallow acreage, and types of crops grown.

description: Due to quantum correlations in the C=-1 and C=+1 D0 D0bar pairs produced in the reactions e+ e- --> D0 D0bar (n pi0) and e+ e- --> D0 D0bar gamma (n pi0), respectively, the time-integrated D0 D0bar decay rates are sensitive to interference between amplitudes for indistinguishable final states. The size of this interference is governed by the relevant amplitude ratios and can include contributions from D0-D0bar mixing. We present a method for simultaneously measuring the magnitudes and phases of these amplitude ratios and searching for D0-D0bar mixing. We make use of fully- and partially-reconstructed D0 D0bar pairs in both C eigenstates. Our method is insensitive to CP violation, and we estimate experimental sensitivities based on a plausible charm factory dataset. Similar analyses can be applied to coherent K0 K0bar, B0 B0bar, or Bs Bsbar pairs.

description: Can one teach entrepreneurship, or is it a fixed personal characteristic? Most academic and policy discussion on microentrepreneurs in developing countries focuses on their access to credit, and assumes their human capital to be fixed. However, a growing number of microfinance organizations are attempting to build the human capital of micro-entrepreneurs in order to improve the livelihood of their clients and help further their mission of poverty alleviation. Using a randomized control trial, we measure the marginal impact of adding business training to a Peruvian village banking program for female microentrepreneurs. Treatment groups received thirty to sixty minute entrepreneurship training sessions during their normal weekly or monthly banking meeting over a period of one to two years. Control groups remained as they were before, meeting at the same frequency but solely for making loan and savings payments. We find that the treatment led to improved business knowledge, practices and revenues. The microfinance institution also had direct benefits through higher repayment and client retention rates. Larger effects found for those that expressed less interest in training in a baseline survey have important implications for implementing similar market-based interventions with a goal of recovering costs.

description: This paper analyzes the influence that juvenile offenders serving time in the same correctional facility have on each other's subsequent criminal behavior. The analysis is based on data on over 8,000 individuals serving time in 169 juvenile correctional facilities during a two-year period in Florida. These data provide a complete record of past crimes, facility assignments, and arrests and adjudications in the year following release for each individual. To control for the non-random assignment of juveniles to facilities, we include facility fixed effects in the analysis. This ensures that the impact of peers on recidivism is identified using only the variation in the length of time that any two individuals serving a sentence in the same facility happen to overlap. We find strong evidence of peer effects for various categories of theft, burglary, and felony drug and weapon crimes; the influence of peers primarily affects individuals who already have some experience in a particular crime category.

description: Highly oriented VO2 thin films were grown on sapphire substrates by the sol-gel method that includes a low pressure annealing in an oxygen atmosphere. This reduction process effectively promotes the formation of the VO2 phase over a relatively wide range of pressures below 100 mTorr and temperatures above 400oC. X-ray diffraction analysis showed that as-deposited films crystallize directly to the VO2 phase without passing through intermediate phases. VO2 films have been found to be with [100]- and [010]-preferred orientations on Al2O3(1012) and Al2O3(1010) substrates, respectively. Both films undergo a metal-insulator transition with an abrupt change in resistance, with different transition behaviors observed for the differently oriented films. For the [010]-oriented VO2 films a larger change in resistance of 1.2x10^4 and a lower transition temperature are found compared to the values obtained for the [100]-oriented films.

description: We prove the existence of one quarter supersymmetric type IIB configurations that arise as non-trivial scaling solutions of the standard five dimensional Kerr-AdS black holes by the explicit construction of its Killing spinors. This neutral, spinning solution is asymptotic to the static anti-deSitter space-time with cosmological constant $-\textstyle{\frac{1}{\ell^2}}$, it has two finite equal angular momenta $J_1=\pm J_2$, mass $M=\textstyle{\frac{1}{\ell}} (|J_1|+|J_2|)$ and a naked singularity.We also address the scaling limit associated with one half supersymmetric solution with only one angular momentum.

description: Solar X-ray Monitor (XSM) instrument of India's Chandrayaan-2 lunar mission carries out broadband spectroscopy of the Sun in soft X-rays. XSM, with its unique features such as low background, high time cadence, and high spectral resolution, provides the opportunity to characterize transient and quiescent X-ray emission from the Sun even during low activity periods. It records the X-ray spectrum at one-second cadence, and the data recorded on-board are downloaded at regular intervals along with that of other payloads. During ground pre-processing, the XSM data is segregated, and the level-0 data is made available for higher levels of processing at the Payload Operations Center (POC). XSM Data Analysis Software (XSMDAS) is developed to carry out the processing of the level-0 data to higher levels and to generate calibrated light curves and spectra for user-defined binning parameters such that it is suitable for further scientific analysis. A front-end for the XSMDAS named XSM Quick Look Display (XSMQLD) is also developed to facilitate a first look at the data without applying calibration. XSM Data Management-Monitoring System (XSMDMS) is designed to carry out automated data processing at the POC and to maintain an SQLite database with relevant information on the data sets and an internal web application for monitoring data quality and instrument health. All XSM raw and calibrated data products are in FITS format, organized into day-wise files, and the data archive follows Planetary Data System-4 (PDS4) standards. The XSM data will be made available after a lock-in period along with the XSM Data Analysis Software from ISRO Science Data Archive (ISDA) at Indian Space Science Data Center(ISSDC). Here we discuss the design and implementation of all components of the software for the XSM data processing and the contents of the XSM data archive.

description: We present a detailed X-ray spectral and variability study of the full 2018 outburst of MAXI J1727-203 using NICER observations. The outburst lasted approximately four months. Spectral modelling in the 0.3-10 keV band shows the presence of both a soft thermal and a hard Comptonised component. The analysis of these components shows that MAXI J1727-203 evolved through the soft, intermediate and hard spectral states during the outburst. We find that the soft (disc) component was detected throughout almost the entire outburst, with temperatures ranging from ~0.4 keV, at the moment of maximum luminosity, to ~0.1 keV near the end of the outburst. The power spectrum in the hard and intermediate states shows broadband noise up to 20 Hz, with no evidence of quasi-periodic oscillations. We also study the rms spectra of the broadband noise at 0.3-10 keV of this source. We find that the fractional rms increases with energy in most of the outburst except during the hard state, where the fractional rms remains approximately constant with energy. We also find that, below 3 keV, the fractional rms follows the same trend generally observed at energies >3 keV, a behaviour known from previous studies of black holes and neutron stars. The spectral and timing evolution of MAXI J1727-203, as parametrised by the hardness-intensity, hardness-rms, and rms-intensity diagrams, suggest that the system hosts a black hole, although we could not rule out a neutron star.

description: The aim of this research is to investigate determinants of firm's intangible investments. The model of Arefmanesh and Rahmani (1394) was used to measure unrecorded and total intangibles. According to literature, Determinants were identified. Structural Equation Model by Partial Least Squares (PLS) path modeling was used to analyze determinants of firm's intangible investments. Analyzing of data panel of 143 firms from 1386 to 1392 indicate firm specific characteristics have significant influence in intangible investments. Firm's Profitability and leverage have positive influence and firm's size has negative influence on firm's intangible investments. Furthermore, results indicate positive effects of industry kind on intangible assets. On the other hand, high and intermediate high tech firms do more intangible investments. Additionally results show that barriers to entry have negative effect on firm's intangible investments. According to research findings from corporate governance mechanisms, only size of board of directors and institutional owners have negative influence and independence of board have positive influence on intangible assets.
