Abstract

Institutional changes, in a historical context, through simultaneous evolutionary and metamorphic processes either deform or reform long-enduring institutions. The chapter delves into the Persian history from the early days of the reign of Nāṣer al-Dīn Shāh-e Qājār in 1848 to the recent years and traces Persian institutions' historical transformations, which culminated to the Persian women entrepreneurship. Thus, the chapter first sets the historical context in each period and then sheds light on the pivotal issues of each period's women. The undergirding base of the discussions is the assumption of the change in institutions as natural metamorphosis in the animate. Finally, the discussions contribute to the conceptualization of the Institutional Triangulation and in the case of Persia, a cultural-driven triangulation, which has paved the way to the formation of a stupendously hegemonic patriarchal and masculine sociopolitical economy in Persia, that has historically affected women's institutionalization, subjugation, subordination, marginalization, socialization, emancipation, and most recently Islamization phases.

Abstract

Past studies on foreign corporate investment and wages hypothesize that by expanding into highly concentrated and highly capital intensive industries, foreign owners are better able to pay higher wages than their domestic counterparts. Our study tests this hypothesis by comparing the effects of domestic and foreign acquisition activity on union and non‐union wages. We find strong evidence supporting the ability to pay hypothesis. There is no indication of bargaining strength changing with foreign acquisitions, as such activity is not associated with larger union wage premiums. Union premiums, however, decline with greater domestic acquisition activity.

Abstract

Purpose

This paper aims to introduce two methods for immobilisation of TiO2 nanoparticles on a glass plate by means of silicon resin as a medium. Then, to ensure the effectiveness of these stabilisation methods, the photocatalytic degradation and mineralisation of the dye C.I. Reactive Blue 21 (RB21), as a model organic pollutant, were compared using these immobilised systems and the suspended one utilizing UV and sunlight irradiations individually.

Design/methodology/approach

TiO2 nanoparticles were supported onto a glass support by silicon resin as an adhesion agent by spraying of TiO2 nanoparticles on the resin surface, which covered the glass plate or brushing the mixture of TiO2 and the resin onto the glass. The characteristics of the applied nano-TiO2 were investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and Brunauer

Emmett–Teller. Photocatalytic degradation and mineralisation of C.I. Reactive Blue 21 (RB21) by two immobilised systems were compared with suspended system in a batch mode under UV and sunlight irradiations after 2 h of treatment.

Findings

The results showed that these immobilised modes had efficiencies, including 82-87 per cent degradation of RB21 and 52-58 per cent decrease in chemical oxygen demand (COD) for the operational time of 120 min, comparable to that of the suspended mode (91 per cent degradation of RB21 and, consequently, COD is decreased by 65 per cent). Comparison between photocatalytic efficiencies of two immobilised systems revealed that coating by spraying method performed better than brushing one due to more available surface area of TiO2. Finally, the results obtained from the mentioned supported systems under sunlight indicated the efficiencies about 87 to 89 per cent in comparison of the suspension system regardless of the reaction time enhancement up to 15 h compared to the UV irradiation.

Research limitations/implications

In this research, the fixation of TiO2 nanoparticles on a substrate such as normal glass by an easy, inexpensive, durable, repairable and repeatable technique for wastewater treatment was introduced. Due to the simplicity and cheapness of these stabilisation methods and as these stabilisation methods are applicable on other substrates such as concrete, ceramics, etc., you can use these methods in major scales for purification of contaminated water, for example for stabilisation of TiO2 nanoparticles on wall pool utilized for water purification can be used.

Originality/value

Two introduced immobilisation methods in this study are novel. The photocatalytic efficiency of these immobilised systems in degradation of water contaminants was investigated by using these systems in degradation and mineralisation of the dye C.I. Reactive Blue 21 (RB21), as a model organic pollutant compared with same TiO2 nanoparticles in an aqueous suspension system under UV light. Furthermore, this paper investigated replacing of inexpensive sources of UV light instead of UV lamps, and then the same photocatalytic reactions were carried out under sunlight as a UV source and degradation efficiencies by two UV sources were compared.

Abstract

Purpose

This study aims to highlight the accuracy, performance and selection of the IPO valuation methods in the Islamic Republic of Iran’s emerging market.

Design/methodology/approach

The authors performed accurate ex ante evaluations based on a pre-IPO data set obtained from valuation institutions. This study considered valuation methods through correlations, Mann–Whitney U tests and regression analysis, using a sample of 83 IPOs from January 2017 to March 2021.

Findings

The authors found that the dividend discount model (DDM) was the most popular in Iran. Even after controlling firm characteristics and market circumstances, the IPO price was highly correlated to pre-IPO reports’ estimates. The results showed that firms’ age, size and profitability affected the selection of valuation methods. The valuers did not apply forward P/E in a volatile market. Firm size affected the weights assigned to free cash flow to the firm, and the valuers considered the asset-in-place intensity to determine the weights of DDM, P/E and net asset value, and they mainly used the P/E to value old firms. Finally, this study estimated the accuracy of the pre-IPO report at 61% and found the highest accuracy to be associated with DDM.

Originality/value

IPO pricing in emerging markets constitutes a more significant dilemma than in developed markets. This paper provides empirical evidence of IPO pricing focusing on valuation methods used in the context of an emerging market – the Islamic Republic of Iran.
