Abstract

Purpose

The use of Twitter by political parties and politicians has been well studied in developed countries. However, there is a lack of empirical work, which has examined the use of Twitter in developing countries. This study aims to explore the information-sharing patterns of Pakistani politicians through Twitter accounts during the pre-election campaign of 2018.

Design/methodology/approach

Data of three weeks of the official party accounts and the politicians running for prime minister were analysed. The mixed-methods approach has been used to analyse quantitative and qualitative data retrieved through Twitonomy.

Findings

It was found that the most active Twitter account belonged to the winning party. The prominent Twitter account functions were a call to vote, promotional Tweets, promises and Tweeting about party developments. The present study provides evidence that there is a difference between the Tweeting behaviour of established and emerging parties. The emerging party heavily posted about changing traditional norms/culture/practices.

Practical implications

The study contributed to existing knowledge and has practical implications for politicians, citizens and social media planners.

Originality/value

The present study was designed carefully and based on empirical research. The study is unique in its nature to fill the research and knowledge gap by adding a variety of Twitter functions used by politicians.

Abstract

Purpose

The emergence of digital technological advances pushes educators for understanding and utilizing these technologies for classroom use. The current generation of teenagers has grown up in a networked world where everyone is immersed in technology-based gadgets in everyday life. Therefore, the purpose of this paper is to investigate video game-based academic and information literacy (IL) learning of teenagers of private schools of Lahore city. Lahore is the capital city of the province of Punjab. Literary works highlighted the importance of video games in developing academic and IL skills; therefore, the current research aims to reveal this fact in local context.

Design/methodology/approach

The present study adopted qualitative research design and utilized phenomenological research method to achieve study’s objectives. The data were collected through face-to-face interviews. The study participants were teenagers (aged 13‒19 years) of elite economic class of private schools where students normally owned latest video game gadgets.

Findings

Based on the study findings, it is elucidated that playing video games has a positive impact on teenagers’ learning, and it promotes quick thinking. The participants exert effort to achieve goals, take up challenges for completing different points at various stages of games and interact with online competitors. It enhanced their social communication, problem-solving and IL (searching/locating and evaluating) skills.

Research limitations/implications

The present study has some limitations. First, sample is limited to elite economic private schools of Lahore. Second, the lack of availability of regular video game players has limited the sample size, as Pakistan is a developing country and limited numbers of teenagers use and can afford gaming gadgets. Lastly, the results of this study are based on students’ perceptions, so there is a need to measure actual learning with assessments.

Originality/value

The results of the study are beneficial for the game developers, teachers, librarians and parents. The education sector may support video games usability as learning tools.

Abstract

Purpose

This paper aims to develop a new method of protein detection in fabric using purified henna extract targeted to be used as a precautionary step by protein contact dermatitis (PCD) patients.

Design/methodology/approach

Henna contains lawsone, which is known for its reaction with amino acid, resulting in the formation of a highly coloured compound. Dye exhaustion test of 2 per cent purified henna extract was done on both protein and non-protein fabric, and the results were analysed using independent samples t-test to assess the significant differences of the comparison. Then, protein fabric indicator was developed by incorporating purified henna extract. It was tested for its dye ability and stability.

Findings

Protein fabrics showed a significant higher dye exhaustion (p = 0.001) in which pure silk came in first with 21.70 per cent ± 2.53, silk/rayon, 13.96 per cent ± 0.55, viscose/wool, 9.57 per cent ± 1.36, cotton/spandex, 5.89 per cent ± 0.86, linen/cotton, 5.26 per cent ± 1.29, cotton, 4.87 per cent ± 1.51, polyester/viscose, 4.69 per cent ± 1.09, linen, 4.56 per cent ± 0.86, polyester/cotton, 3.90 per cent ± 0.29 and polyester and 3.88 per cent ± 0.66. Two different forms of protein fabric indicator were developed: capsule and tablet. Both indicators showed good observable dye exhaustion and fixation results. Orange henna dye was fixed on protein fabric while non-protein fabric returned to its original colour after washing procedure. However, the tablet form showed better performance in terms of functionality and stability.

Originality/value

This study will help general community to better understand fibre and its constituents, especially protein where clothing is an integral part of human life because it comes in direct contact with the human skin. As PCD caused by clothing and textile is an uncommon disease, it may also help in creating awareness on how some people may develop contact dermatitis through fabric. This is because the fabric’s protein content is a causative allergen, which most people tend to overlook. For the researcher, this study helps to elucidate some critical areas in PCD for clothing and textile as this topic can be considered an understudy. There is no standard method to detect protein in fabric, especially blended fabric. Thus, a portable kit to detect protein in fabric will be developed in this study. This kit will benefit PCD patients to ease them in finding the right fabric for their skin.

Abstract

Purpose

The purpose of this paper is to develop the bio-composite organic coatings by adding the bio-based additives that are extracted from banana peels and henna leaves as the organic corrosion inhibitors.

Design/methodology/approach

Bioactive constituents with inhibition properties are extracted from banana peels and henna leaves by using ethanol to form the ethanolic extract. The inhibiting efficiency of these bioactive constituents on mild steel corrosion in 3.5% sodium hydroxide (NaCl) solution is investigated. The investigation is performed using electrochemical impedance studies for 30 days. The optical and adhesive properties of the bio-composite coating systems have also been studied.

Findings

The best protection is obtained as the loading ratio of the banana peels ethanolic extract (BPEE) and henna leaves ethanolic extract (HLEE) are 10 Wt.% and 30 Wt.%, respectively. Overall, the results obtained show that the BPEE and HLEE not only enhance the optical properties but also can serve as an effective inhibitor for corrosion without affecting the adhesiveness of the neat acrylic properties.

Originality/value

Banana peels and henna leaves consist of bioactive constituents that have anti-corrosion properties which could inhibit corrosion.

Abstract

Purpose

The purpose of the paper was to investigate the use of aqueous extract of date palm (Phoenix dactylifera) leaf as a green inhibitor for corrosion of carbon steel in 1M hydrochloric acid (HCl) solution.

Design/methodology/approach

Extracts from the date palm were used as the main component of an environmentally friendly corrosion inhibitor for use in HCl pickling processes. Inhibition behavior on carbon steel in HCl was investigated using weight loss measurements, linear and potentiodynamic polarization curves, electrochemical impedance spectroscopy and scanning electron microscopy.

Findings

The results show that the extract exhibited good inhibition performance in 1M HCl. The inhibition efficiency increased with increase in the concentration of the inhibitor but decreased with increase in temperature. Inhibition efficiency also was found to increase as immersion time increased. The inhibitive action was due to adsorption of the date palm leaf components on the steel, which was consistent with the Langmuir isotherm.

Practical implications

Date palm leaf extract (DPLE) is an effective inhibitor at room temperature and can be used to protect plain carbon steel from corrosion in HCl solution.

Originality/value

This study provides new information on the inhibiting characteristics of DPLE under specified conditions. The environmentally friendly inhibitor could find possible applications in metal surface anodizing and acid pickling processes.

Abstract

Although Research in Economic Anthropology (REA) actually hit the quarter-century mark in 2003 with the publication of Volume 22, the series has now done so also in terms of the number of volumes. Twenty-five seems like an important milestone, and perhaps this edition can be noted for passing that, but it also marks the third editorial change in the history of REA. When a new editor takes over, it seems prudent to offer a summary of the book series’ evolution to date. As many know, George Dalton was the original editor – beginning in 1978 (REA was then published by JAI Press). Dalton subsequently handed the reins to Barry Isaac, who produced Volumes 6 through 20, along with a number of supplemental publications that focused on specific topics or regions and contained only chapters of an archeological or ethnohistorical nature. In fact, Isaac is still recognized for his efforts at granting archeology an equal footing with ethnology in the study of human economic behavior.1 While Dalton included previously published material in the pages of REA and welcomed works by non-anthropologists, Isaac considered only original manuscripts and generally limited his selection of chapters to those written by anthropologists. Since Volume 20, REA has been published by Elsevier.

Abstract

Purpose

The purpose of this paper is to reveal the potential use of faba bean husk as natural dye, to create a color gamut and to observe the effect of different mordants. Dyeing properties of polyamide/elastane fabric using faba been husk were investigated. The effect of alum [KAl(SO4)2], iron II sulfate Fe(SO4)7H2O, tin II chloride (SnCI22H2O), copper II sulfate (CuSO4), citric acid (C6H8O7), tartaric acid (C4H6O6), oxalic acid (H2C2O4), ammonium sulfate [(NH4)2SO4], sodium acetate (C2H3NaO2), combination of alum-iron, iron-tin and alum-tin were evaluated in terms of color yield, color coordinates and wash fastness.

Design/methodology/approach

Mainly, dyeings were conducted in accordance with a simultaneous mordanting method. However, pre-mordanted dyeings were also implemented with selected concentration (0.8 g/L) of metallic mordants to enrich color gamut. Control sample (without mordant) was used as a reference for examining the effect of different mordants. Dyed samples were compared mutually in the light of visual evaluation and color measurements and alternatives to metallic mordants were also assessed.

Findings

Significant differences occurred in color coordinates of dyed samples. The biggest color difference and completely different color shades were achieved with tin II chloride. The type of acid did not create visible color differences. As alternatives to metallic mordants; all of them may be used instead of alum (0.8 g/L). Tartaric acid and oxalic acid, instead of iron II sulfate (0.2 g/L), and ammonium sulfate (0.2 g/L) and sodium acetate (0.8 g/L), instead of alum (0.8 g/L), can be used. Sodium acetate cannot be replaced with iron. A combination of alum-iron and iron-tin can be the alternative to 0.2 and 0.8 g/L copper, respectively. All the samples provided good wash fastness (4/5) values.

Originality/value

Valorization of industrial, agricultural and domestic wastes as novel natural dye sources is an ecological and sustainable approach. Moreover, the use of man-made fibers in natural dyeing is an issue that needs to be developed and expanded. Few literatures have been found concerning the use of husks of faba bean as a natural colorant. In this initial study, husks of faba been as a vegetable waste were utilized in natural dyeing of polyamide/elastane fabric. It is suggested that this waste can be turned into an economic value through its valorization in natural dyeing.

Abstract

Encouraging entrepreneurship has become an accepted wisdom in economic management and government policy. It could only be a matter of time before the world of education was invoked as a means of furthering this end. Business schools have not made the most incisive contribution possible, and there is a significant expectations gap. So as we cascade down to the secondary level, efforts are being made to improve matters. The initiative of the National Foundation for Teaching Entrepreneurship is outlined, and research results relating to impact are provided. This is a systematic and comprehensive approach, which started in the USA and has currently spread abroad. It has been well received, and is a suitable means of planting seeds that may come to fruition in later life. It is an action learning approach, which is an excellent vehicle for teaching business studies. It has proved itself in widening access to under‐privileged groups.

Abstract

Purpose

The purpose of this paper is to study the ability of commercial tara powder to convert rust into iron tannate and evaluate their use as raw material for the formulation of water based rust converter.

Design/methodology/approach

Water-borne acrylic primers were formulated with tara powder and aqueous tara extract and applied on steel rusted by three different methods. The conversion of rusted steel by tara tannins was studied by X-ray diffraction spectroscopy, infrared spectroscopy and scanning electron microscopy. The acrylic primers, containing hydrolysable tannins, were coated with alkyd finish and were evaluated in comparison to commercial systems in accelerated corrosion tests. The corrosion inhibition effects of tara powder on mild steel in 0.1M NaCl were studied by DC electrochemical techniques.

Findings

Tara tannin converts rust to ferric tannate and increases the magnetite content of rusted steel. The water-based acrylic primer formulated with aqueous extract of tara, alkyd-coated finish, showed performance equivalent to pure alkyd system.

Research limitations/implications

The chlorides content in the commercial tara powder can be screened the beneficial effect of hydrolysable tannins to convert rust. Furthermore, the water-based rust converter formulated with acrylic resin may be sensitive to salt contamination of rust.

Originality/value

Hydrolysable tannins from commercial tara powder have not been studied yet in its application to the development of rust converters. A water-based primer formulated with commercial tara powder developed for the effective treatment of rusted surfaces can be of interest as an environmentally friendly to current commercial approaches.

Abstract

Purpose

The purpose of this paper is to make people aware of organic corrosion inhibitors.

Design/methodology/approach

As it is a literature review paper, no specific method is used.

Findings

It has been found that plant extracts and oils show inhibition efficiency up to 98 percent, so it is certain that plant extracts and oils are effective corrosion inhibitors and can be successfully used at the industrial level.

Research limitations/implications

Plant extracts and oils are also found to be non‐toxic, highly efficient, renewable and cheap. But less effort has been given towards the identification of which compound is active in the extract.

Originality/value

The paper shows detailed account of the inhibitors obtained from plants, which are used as natural corrosion inhibitors.
