Risk and return are the most important components in the financial and investment world and the existence of a better balance between them with the goal of the best solution for investing in different assets has always been studied and discussed by researchers. For this purpose in this study introduced the Hybrid Balanced Justified Treynor ratio (HBJTR) criterion.

This study introduced the HBJTR criterion, which has three major attributes, including combination of both the frequency and severity of the risk using Markov regime switching model which was modeled on the Justified Beta (Jßi). The second is the merger of data of both the cycles of boom and recession, which was modeled on the Hybrid Justified Treynor Ratio (HJTR). The third was the balancing act in two periods of boom and recession, which was introduced on the HBJTR model.

Based on a weighted averaging of the Justified Treynor ratio of both the cycles of boom and recession, which was introduced by the HJTR term in this study, the superiority in the first grade related to the two indexes were sugar index (0.0096) and insurance index (0.0053). Finally, using the final model in this study, namely HBJTR, the overall advantage was the defensive index, i.e. the insurance index of 1.23.

In other words, the HBJTRi criterion consists of three steps: first, the Justified Beta (Jßi) and Justified Treynor ratio of each index using two regimes of Markov switching model were calculated for each of the cycles of boom and recession separately according to formulas 8 and 9. In the second step, the weighted average was taken from both Justified Treynor ratios of boom and recession cycles, which was called the HJTR. In the third step, to calculate the HBJTR criterion

The tremendous and highly complex industrial development which went on with ever‐accelerating rapidity during the latter half of the nineteenth century brought the USA face‐to‐face at the beginning of the twentieth century with the very serious social problem of crime. This article examines whether there was any relationship at all between crime, unemployment and sales of alcohol and, if there was a relationship, whether the two domains shared two, as opposed to only one dimension and what the pattern of relationships were relating variables in one domain with those in the other.

Theories of crime and delinquency tend to be discipline‐specific and are dominated by psychological, sociological, and economic approaches. The focus of this article will be on an economic approach to understanding criminal behavior and the design of effective policies for dealing with the problem of criminal activity. From an economic perspective, crime is rational behavior, a choice that is made by people in deciding how best to spend their time. In making the choice, individuals consider the benefits and costs of using their time in different ways: working legally, working illegally, or not working at all. This article examines the correlations between economic variables and a broad measure of crime, the property crime rate. The results reveal that even a very parsimonious model, which includes the poverty rate, gross domestic product, and drug seizures, can explain nearly 75 percent of the variation in the crime rate over an 18‐year period.

The purpose of this paper is to investigate the effects of combined risperidone (RIS) and pivotal response treatment (PRT) in children with autism spectrum disorder (ASD).

In all, 34 children diagnosed with ASD (mean age of 12.36 years) were randomly divided into two groups: an RIS treatment group (n=18) and an RIS plus PRT (n=16). Communication skills were evaluated with the child communication checklist (CCC).

Total score of the CCC was increased in both groups after three months compared with the score prior to treatment. The total score of the CCC was significantly higher in the combined treatment group than in the RIS group.

Treatment with RIS combined with PRT may result in a better outcome in communication skill for children with autism than RIS training alone.

Insufficient physical activity leads to an increase in chronic diseases. Skills-based health education methods are supposed to be more successful than traditional methods to promote healthy behaviors. Skills-based health education is an approach to create healthy lifestyles and skills using participatory methods. The purpose of this paper is to examine the effects of skill-based education method on physical activities of female adolescents.

This was an experimental study on 80 female public high school students aged 12-14 years old in Tehran. The participants were randomly divided into two groups: experimental group of 40 girls who were educated using “Skills-based education method,” and control group of 40 girls who were educated by lecture as a routine educational method for health promotion. Data were collected using a valid and reliable questionnaire to assess physical activity-related knowledge, attitudes and behavior. Data were gathered three times; before, immediately after (Phase 1) and two months after educational intervention (Phase 2). Data analysis was performed using SPSS 20.

Intra-group comparison demonstrated that both educational methods can increase knowledge, attitude and behavior of the students after intervention comparing to before intervention (RMANOVA; p<0.05). However, the comparison between groups demonstrated a significant higher increase of knowledge (t-test; p<0.01 and p<0.0; phase 1 and 2, respectively), and behavior (t-test; p<0.01 and p=0.002; phase 1 and 2, respectively) but not attitude (p=0.083 and p=0.125, phase 1 and 2, respectively) among the students participated in the experimental “skilled based health education” group rather than the control “lecture” group.

Skill-based health education comparing to routine lecture-based education creates deep and long lasting knowledge and behavior and is highly recommended for promoting physical activity and other health-related knowledge and among adolescents.

This paper aims at discovering the traditional techniques of Persian architecture for covering large-span spaces with a kind of ribbed vault titled “Karbandi”. This structure is generated by intersecting several arches with a harmonic stellar geometry. Preliminary studies show that span factor affects the structural form of karbandi and large-span cases, despite similar architectural forms, have different structural systems and specific construction methods. The main focus of this paper is how karbandi has been designed and built on large-spans. To answer this question, the configuration and construction of a large-span karbandi in Tabriz Bazaar were recognized.

Data collection of the research was initially done in three parallel directions through the archival study of restoration documents, direct observation of the corpus of the vaultings and interviews with the master mason of the Haj-Mohammad-Qoli Timche restoration team. Then by cross-referencing the gathered data, the construction process of the karbandi was simulated in Rhino 6 and Grasshoppers software and its BIM-M models were created in three levels of development: LOD300, LOD350 and LOD400. In the next step, the preliminary BIM-M models of the karbandi were presented to the interviewed mason and revised and completed based on his comments.

Analyzing the BIM models by reverse engineering, resulted in (1) Discovering a unique self-supporting masonry construction method applied for the erection of karbandi vaulting on large-spans. (2) Finding the effect of scale factor on the architectural and structural form of the karbandi vault. (3) Discovering the connection types of the karbandi vault based on the construction details.

Despite the wide applications of karbandi vaults throughout history, very little information of their construction techniques is available. The techniques have mostly been experientially and orally passed down from masters to apprentices and rarely been documented. The quest to design and construct a karbandi vault is therefore like solving a puzzle whose most important guide is historical cases. Due to the geometric complexity of karbandi and its ability to cover large-span spaces, solving the puzzle can lead to achieving some technical ideas for masonry cross-ribbed vaulting. A great riddle of the karbandi vaults is how to design and build them on a large span.

To the best of our knowledge, the studies on determining adherence to the Mediterranean dietary pattern (MDP) in Iran as a non-Mediterranean country are scarce. Thus, the aim of the study is to determine the adherence to the MDP in a sample of female adolescents who are residents of Tehran, Iran.

In this cross-sectional study, 263 female adolescents aged 15-18 years were studied. Information on socio-demographic, lifestyle and anthropometric variables were obtained using a structured questionnaire. Also, dietary intakes were determined using a validated 168-item food frequency questionnaire. Adherence to MDP was characterized using Mediterranean-style dietary pattern score (MSDPS).

Typically, the mean ± SD MSDPS was low in the present study (15.9 ± 5.6). The mean ± SD age and body mass index of the study population was 16.2 ± 0.9 years and 22.2 ± 4.1 kg/m², respectively. In this study, the maximum MSDPS was 34.3, which was only one-third of maximum possible score (100). Multiple linear regression analyses showed that higher MSDPS scores were positively associated with age (standardized β = 0.1; p = 0.006), higher energy intake (standardized β = 0.2; p < 0.001) and marginally higher physical activity (standardized β = 0.1; p = 0.079).

Understanding low adherence to MDP in Tehranian female adolescents can provide basic knowledge to launch systematic programmes for gravitation toward MDP.

This chapter examines destination risk perceptions of domestic pilgrims in Mashhad, Iran. Self-reported questionnaires were distributed to visitors of Imam Reza shrine in Mashhad through a time-based systematic random sampling method. Partial least squares structural equation modeling was used for data analysis. Results indicate that perceived risk was associated negatively with the quality of past visits, nonvictimization experience, and destination loyalty. Having past visit experiences did not moderate the strength of the model’s structural links except for the perceived risk to loyalty. The findings provide insights into distinct risk perceptions that can be leveraged by destination planners to tailor business strategies to meet quality expectations.

Kuala Lumpur, the capital of Malaysia, is exposed to several natural hazards, among which flash floods are most common and frequent. Expanding development and higher intensity of rainfall are the primary causes of flash floods. As the urbanisation is growing, the number of exposed properties, people and business premises are also increasing. This may have a detrimental impact on the socio-economic state of the city. Therefore, the purpose of this chapter is to investigate the frequency and intensity of flash flood occurrences between 2011 and 2016 and to delineate how it is impacting the urban livelihood. For this study, several news reports of flash flood events, previously published and reports were reviewed to elicit information so that the frequency and intensity of flash floods can be analysed for identifying flash flood risk areas. Along with the information from newspapers, Google map was used to identify the spatial locations of flash flood events, thus identifying the risk zones. This study found the City Centre as the most risk prone to flash floods. It was noted that 39% of flash floods occurred in this place. The Damansara-Penchala area comes in the second position with 20% of flash floods occurring in this place. Most of the people of these zones are exposed to flash flood and the affected people suffer from road blocking and heavy traffic jam. This study will help researchers and policymakers to understand the impact of flash floods in the city. This will also help to identify the most flood-prone areas of the city.

The purpose of this study is to examine the impact of financial statement comparability as a qualitative feature of financial reporting on cash holdings and the mediating role of disclosure quality and financing constraints in firms listed on the Tehran Stock Exchange (TSE).

Using panel data from 110 TSE-listed firms from 2011 to 2017 in Iran, this study uses the regression analysis to examine the research hypotheses. The first hypothesis examines the relationship between financial statements comparability and cash holdings and two other hypotheses examine the mediating role of financing constraints and disclosure quality in this relationship.

Based on pecking-order theory and institutional context of Iranian firms, the results show that financial reporting comparability has a significant negative impact on corporate cash holdings. The results also show that disclosure quality and financing constraints have no mediating role in the relationship between accounting comparability and cash holdings. The robustness tests with alternative measures of accounting comparability and cash holdings support the findings of this study.

The limitations of this study are as follows: limited number of TSE companies that have necessary data to conduct research; and using the disclosure quality scores provided by TSE organization.

The findings suggest that creditors should consider the financial status and also the quality of financial reporting of companies, before granting credit to them. It is also recommended that regulators in the capital market publish the ratings of companies in terms of financial statement comparability alongside the disclosure ratings and a continuous regulatory oversight on companies.

To the best of the authors’ knowledge, this is the first empirical research on the effect of accounting comparability on the level of cash holdings that examines the mediating role of financing constraints in the context of Iran market as an emerging economy. Moreover, this is the first empirical research that studies the effect of disclosure quality on this relationship.
