In-feed native ads have become a major social media advertising format. The purpose of this paper is to investigate strategies for leveraging native advertising in terms of content creation and platform selection on social media, proposing that variations in content and platform reduce the intrusiveness of native ads, thereby resulting in enhanced brand attitude and purchase intent.

Two experiments were conducted with online samples, employing a 2 (content strategy: repeated ads vs varied ads) × 2 (platform strategy: single platform vs multiple platforms) between-subject factorial design. ANCOVA and structural equation modeling were used to test the hypotheses.

When repeated ads were used, the use of multiple platforms reduced ad intrusiveness, resulting in more favorable brand attitude and greater purchase intent as opposed to the use of a single platform. In contrast, when varied ads were used, there were no significant differences in the outcome variables between a single platform and multiple platforms. The results were largely consistent across the two experiments.

This study contributes to theory advancement by unpacking the underlying mechanisms of processing native advertising and shedding light on which content and platform strategies are the most effective on social media.

This study aims to analyze iodine content in various foods and water.

Food and water samples were collected from rural and urban areas of different agroclimatic zones of Haryana State, India, and analyzed for iodine content by a standard method.

A wide variation was observed in the iodine content of cereals, pulses, vegetables, fruits and milk. The iodine content in water samples varied from source to source and from zone to zone.

The investigators could not obtain sufficient samples of pulses and fruits for analysis from rural areas as they are not grown by farmers in their fields.

The study is original and innovative. The values of iodine for various foods are not available in the literature, and thus data of the present study will be useful to researchers, nutritionists, food scientists and dieticians.

The purpose of this paper was to determine the complex permittivity of bismuth strontium manganites (Bi_1−xSr_xMnO₃) in the 8‐12 GHz range by using perturbation of Ag thick film microstrip ring resonator (MSRR) due to superstrate of both bulk and thick film.

The BSM ceramics were synthesized by simple low cost solid state reaction method and their fritless thick films were fabricated by screen printing technique on alumina substrate. A comparison has been made between the X band response of Ag thick film microstrip ring resonator due to perturbation of bulk and thick film Bi_1−xSr_xMnO₃ ceramic.

The bulk and thick film superstrate decreases the resonance frequency of MSRR. In this technique even minor change in the properties of superstrate material changes the MSRR response. Variation of strontium content also influences microwave conductivity and penetration depth of bulk and thick films.

The microwave complex permittivity decreases with increase in Sr content in bismuth manganite and it is higher for bulk as compared to its thick films. The superstrate on Ag thick film microstrip ring resonator is an efficient tool capable of detecting the composition dependent changes in microwave properties of ceramic bulk and thick films.

The purpose of this paper is to determine the physicochemical characteristics of yellow and red apples cultivars of cashew. This is with a view to harnessing the quality attributes of the different cultivars of cashew. Parameters investigated include pH, refractive index, specific gravity, vitamin C content, juice astringency, chlorophyll and juice yield.

The methods of the Association of Official Analytical Chemists (AOAC) are employed in assaying the physicochemical properties, while the astringency is determined spectrophotometrically according to standard methods.

Results showed that percentage juice yield increases linearly with maturity for both cultivars. A maximum of 79.5 per cent is obtained for the yellow apple cultivars, while 74.1 per cent juice yield is obtained in the red apple cultivar. The pH ranged from 3.73‐4.5 and 3.64‐4.55 for red and yellow apple cultivars, respectively, with a marked fall between seven and eight weeks after pollination (WAPo). Specific gravity and refractive index are of the order 0.999‐1.007 and 1.34‐1.89 for both selected samples. Highest refractive index is obtained in red and yellow cultivars at seven and eight WAPo. The changes in ascorbic acid followed a linear pattern and the maximum values of 249.5 mg/100 ml and 185.5 mg/100 ml are obtained for yellow and red apple cultivars, respectively. Meanwhile, the juice astringency level decreased steadily with maturity and at the ninth WAPo, values obtained are 0.47 and 0.86 mg/100 ml tannin for yellow and red apple cultivars, respectively. Generally, pH, astringency, refractive index, juice content, ascorbic acid and chlorophyll contents showed marked variations between six and eight WAPo, confirming physiological maturity and ripening in the crop species.

Cashew farmers and industrialists will know the best time to harvest the crop when the quality is at its peak.

The excessive consumption of alcohol by young people is a current and controversial issue in New Zealand (NZ) and Australia. The literature suggests that such consumption is an accepted social norm, and that young people deliberately drink to reach a level of intoxication. Current public policies to reduce consumption, beyond education through media campaigns, include taxation to raise the price and movements to limit the allowable alcohol content in some beverages popular with youth. This paper aims to determine whether price or alcohol content changes will have any effect on youth drinking.

An experiment was conducted in both Australia and NZ to examine the effects of price changes and alcohol content changes on behavioural intention. A third implied hypothesis was also examined ‐ do Australian students differ from NZ students in their behaviour? Students were assigned to one of eight treatment groups, and their purchase intent was measured for ready‐to‐drink (RTD) products. Chi‐squared analysis was undertaken to test the hypotheses.

Results suggest that social norms are stronger than price effects in both countries, and that alcohol content has a significant effect in NZ. These findings contradict government emphases on fiscal and regulatory approaches to modify purchase behaviour.

This study is the first to specifically look at price and alcohol content manipulations and their potential effects on young consumers. As such it sheds light on a current marketing/social issue that has a potentially significant impact on young consumers worldwide.

A comprehensive review of the literature established that several investigations have been made of operations management teaching in the USA, whereas almost nothing has been published on European teaching. Therefore, an exploratory investigation was made of operations management teaching on the MBA courses of ten leading European business schools. The results show that course content is similar across schools, but there are large variations on three dimensions: the time allocated by schools to the subject; the balance between operations strategy and tools and techniques in teaching; and the level of emphasis given to service operations. The results also indicate the emerging importance of integrating operations management with other subjects in the MBA curriculum and the key challenge facing faculty ‐ the need to raise the perceived importance of operations management. The comparison of courses will be of interest to all operations management faculty who teach core courses and particularly those who are looking for ideas on how to re‐design courses.

This study aims to examine the moment-to-moment (MTM) effects of in-consumption dynamic comments on consumers' responses to digital engagement and the underlying mechanisms involved, as well as the interactive role of advertisements embedded in short-form online video.

This study uses data extracted from 2,081 videos posted on the prominent Chinese online live platform, Bilibili. The hypotheses are tested using regression models and natural language processing.

The results indicate that the intensity of live comments at the beginning negatively affects users' digital engagement, while a corresponding increase in live comments at the end elicits a positive effect. A linear trend and peak difference in live comments intensity positively affect digital engagement, while the variability of live comment intensity exerts a negative effect. These MTM effects were driven by sentiments of live comments. Furthermore, in-video advertisements are likely to amplify the negative beginning effect on users' digital engagement and mitigate the negative variability of live comments.

This study is the first to examine the direct effects of MTM comments from the online temporal sequence perspective, differentiating the process- and performance-based engagement. The mechanism and interactive role of in-video advertisements were identified. These findings contribute to literature on interactive marketing and provide valuable guidance for influencer marketing.

The purpose of this paper is to suggest ways that we can widen our vision since our views are limited by our theoretical lens.

The paper first draws on articles in the current issue to illustrate how limitations imposed by our theoretical lens can be partly overcome. It then draws on the insights from two recent papers by Svensson (2016) and Lo and Chik (2016) to discuss some ways forward. Svensson’s paper argues for integrating research on teaching and learning using case-based studies and the contextual analysis approach. Lo and Chik’s paper is about how our learning can go beyond the single case through attending to fusion in the external horizon. The conceptual lens from these two papers which are from the phenomenography, variation theory and learning study tradition is applied to look at some of the papers in this issue which are from the lesson study tradition.

Although there is an inherent limitation to what we can see as a consequence of the theoretical lens that we take, we can widen our vision by learning to see from others’ perspectives and gain insights that would be useful to us.

The conceptual lenses from the phenomenography, variation theory and learning study tradition is applied to look at some of the papers which are from the lesson study tradition to reveal alternative ways of seeing.

The purpose of this study is to advance the application of pulverised cow bone ash (PCBA) as a partial replacement of cement in soil stabilisation for the production of bricks. The study investigated the impact of PCBA substitution on the characteristic strength of clay bricks under variant curing media.

Dried cow bones were pulverised, and an energy-dispersive X-ray fluorescence test was conducted on PCBA samples to determine the chemical constituents and ascertain the pozzolanic characteristics. Ordinary Portland cement (OPC) and PCBA were blended at 100%, 75%, 50%, 25% and 0% of cement substitution by mass to stabilise lateritic clay at 10% total binder content for the production of bricks. The binder-to-lateritic clay matrixes were used to produce clay bricks and cylinders for compressive and splitting tensile strength tests, respectively.

The study found that PCBA and OPC have similar chemical compositions. The strength of the clay bricks increased with curing age, and the thermal curing of clay bricks positively impacted the strength development. The study established that PCBA is a suitable substitute for cement, up to 25% for stabilisation in clay brick production.

Construction stakeholders can successfully use a PCBA-OPC binder blend of 1:3 to stabilise clay at 10% total binder content for the production of bricks. The stabilised clay bricks should be cured at an elevated temperature of approximately 90°C for 48 h to achieve satisfactory performance.

The PCBA-OPC binder blend provides adequate soil stabilisation for the production of clay bricks and curing the clay bricks at elevated temperature. This aspect of the biomass/OPC binder blend has not been explored for brick production, and this is important for the reduction of the environmental impacts of cement production and waste from abattoirs.

This paper aims to establish the microstructures and the process-structure relationships in duplex stainless steel powders consolidated by selective laser melting (SLM).

A priori data on energy density levels most appropriate to consolidation of duplex stainless steel powders through SLM served as the basis to converge on the laser settings. Experimental designs with varying laser power and scan speeds and test pieces generated allowed metallographic evaluations based on optical and scanning electron microscopy and electro backscatter diffraction analyses.

Duplex stainless steel powders are established for processing by SLM. However, the dynamic point heat source and associated transient thermal fields affect the microstructures to be predominantly ferritic, with grains elongated in the build direction. Austenite precipitated either at the grain boundaries or as Widmanstätten laths, whereas the crystallographic orientations and the grain growth are affected around the cavities. Considerable CrN precipitation is also evidenced.

Duplex stainless steels are relatively new candidates to be brought into the additive manufacturing realm. Considering the poor machinability and other difficulties, the overarching result indicating suitability of duplex powders by SLM is of considerable value to the industry. More significantly, the metallographic evaluation and results of the current research allowed further understanding of the material consolidation aspects and pave ways for fine tuning and establishment of the process-structure-property relationships for this important process-material combination.
