Abstract

TV advertising is not what it used to be for Kids and Young Adults. There's a proliferation of programming and channel choice; more communication clutter and poorly targeted, lower quality TV commercials. Moreover the New Media is biting into the time that young people watch TV at home which of course includes the Ads. The Internet will become more important to this target market as penetration increases and broadband delivery becomes the affordable norm. But using Ad Banners to do the job alone will not suffice in today's Net Generation Culture. This article discusses the key issues confronting marketers who want to get mote ‘click’ from their ‘digital spends’.

Abstract

Purpose

The purpose of this paper is to demonstrate laser microvia drilling of polyimide thin films from multiple sources before metallic sputtering. This process flow reduces Flexible Printed Circuit Board (FPCB) material, chemical and operational costs by 90 per cent in the construction of flexible circuits.

Design/methodology/approach

The UV laser percussion drilling of microvias in 25 μm thick polyimide films with low coefficients of thermal expansion (CTE) and elastic modulii was investigated. Results were obtained using Scanning Electron Microscopy and Surface Profilometry. Polyimide films tested included: Dupont™ Kapton® EN; Kolon® GP and LV; Apical® NPI; and Taimide™ TA‐T.

Findings

There was no direct relationship between the top and bottom diameters and ablation depth rates between the polyimide films tested using the same test conditions. There was a direct relationship with exit diameters and etch rates at different laser pulse frequency rates and fluence levels. Laser pulse rates at 30 kHz produced 20 per cent larger exit diameters than at 70 kHz, however at 70 kHz the first pulse etched 16.5 per cent more material. High fluence levels etched more material but with a lower etch efficiency rate. Other microvia quality concerns such as surface swelling, membrane residues on the bottom side and surface debris inside the microvias were observed. Nanoscale powder‐like surface debris was observed on all samples in all test conditions.

Originality/value

This is the first comparison of material specifications and costs for films from multiple polyimide manufactures and laser microvia drilling. The paper also is the first to demonstrate results using a JDSU™ Lightwave Q302® laser rail. The results provide the first insights into potential microvia membrane issues and debris characteristics.

Abstract

Purpose

The purpose of this paper is to analyze the attribute preferences of buyers of branded pulses and to study the differences in preferences between consumers who purchase from traditional retail stores and those who purchase from modern retail stores.

Design/methodology/approach

A total of 300 respondents (150 respondents from traditional and 150 respondents from modern retail outlet) participated in the study. Conjoint analysis was used to assess the consumers’ attribute preferences for branded pulses.

Findings

For both traditional and modern retail outlets, profile with highest utility was the profile with established brand, low price, high quality and normal packaging.

Research limitations/implications

Shoppers of traditional and modern retail outlets have similar attribute preferences for branded pulses. Hence, it can be concluded that the purchase point makes no difference in consumer attribute preferences.

Practical implications

Results indicate that in both traditional and modern retail outlet customers prefer the same profile of attributes. Two important attributes determining their purchase are also the same. Hence a company entering into the sale of branded pulses will have to focus on these two important attributes irrespective of the purchase point.

Originality/value

The topic is relatively less researched in emerging markets especially where both branded pulses and organized retail are in their nascent stages.

Abstract

Purpose

This study seeks to examine empirically import demand for total pulses, chickpeas and lentils in India based on the concept of unit root and cointegration.

Design/methodology/approach

The Stock‐Watson dynamic OLS (DOLS) model – which is robust to small sample and eliminates simultaneity bias – is used to derive the long‐run price, income and urbanisation elasticities of import demand. The data covers the period 1970‐2000.

Findings

Results indicate that real GDP, relative price and urbanisation are the key determinants of import demand for pulses in India. The estimated long‐run elasticities of import demand with respect to income (relative price) are 0.4 (−1.7) for chickpeas, 0.56 (−0.87) for lentils and 0.36 (0.00) for total pulses. The estimated long‐run elasticities of import demand with respect to urbanisation are 9.9 for chickpeas, zero for lentils and 7.2 for total pulses. The policy implications of the results are discussed.

Originality/value

Provides evidence that the response of import demand for pulses to key determinants differ substantially from product to product.

Abstract

As microelectronics continue to shrink, it is becoming increasingly difficult and expensive to mechanically drill very small via holes (<0·010 in.). Using lasers and optical technology, it is possible to drill any material. Thin circuit board materials of various compositions were investigated as candidates for laser drilling using a 100 watt CO2 laser. Laser variables were pulse frequency, duty cycle, and number of pulses (total energy delivered). Delivered energy seems to be the most critical parameter, and the optimal holes were drilled within a narrow energy band, although there was much data scatter. The best laser drilled holes were of lower quality than that obtainable with mechanical drilling. Photographs of the best holes in all materials are included.

Abstract

Purpose

The purpose of this paper is to investigate the selective laser melting (SLM) of Inconel 625 using pulse shape control to vary the energy distribution within a single laser pulse. It aims to discuss the effectiveness of pulse shaping, including potential benefits for use within SLM.

Design/methodology/approach

Laser parameters were varied in order to identify optimal parameters that produced thin wall parts with a low surface roughness without the use of pulse shape control. Pulse shape control was then employed to provide gradual heating or a prolonged cooling effect with a variety of peak power/pulse energy combinations. Properties of pulse shaped and nonpulse shaped parts were compared, with particular attention focused on part surface roughness and width.

Findings

High peak powers tended to reduce top surface roughness and reduce side roughness as recoil pressures flatten out the melt pool and inhibit melt pool instabilities from developing. Ramp up energy distribution can reduce the maximum peak power required to melt material and reduce material spatter generation during processing due to a localized preheating effect. Ramp down energy distribution prolonged melt pool solidification allowing more time for molten material to redistribute, subsequently reducing the top surface roughness of parts. However, larger melt pools and longer solidification times increased the side roughness of parts due to a possible lateral expulsion of material from the melt pool.

Originality/value

This paper is the first of its kind to employ laser pulse shape control during SLM to process material from powder bed. It is a useful aid in unveiling relationships between laser energy distribution and the formation of parts.

Abstract

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Abstract

Purpose

In this paper, knowledge concerning the meaning of knowing the object of learning is developed using learning study as a research approach. The purpose of this paper is to show how the object of learning, in this case, playing with groove in rhythmic sequences, can be analysed and recognised using phenomenography.

Design/methodology/approach

The paper reports on a learning study conducted in three different fifth grade elementary school classes. Seven music teachers were involved in preparing the pre-test, designing three research lessons and analysing the material.

Findings

The findings show that several aspects of the object of learning must be discerned by the learner in order to experience the chosen object of learning and develop in the learning situation. The phenomenographic analysis contributed to refining the meaning of the object of learning.

Originality/value

In a learning study, knowledge concerning the meaning of the object of learning is generated. The development and specification of this knowledge will be empirically revealed through the analysis process. This paper will contribute to the discussion concerning what must be known in order to develop a specific capability in music education, namely, the capability to feel the groove.

Abstract

Purpose

This paper aims to understand the significant farm and market-level factors that incentivize the adoption and marketing of pulses influencing its supply response to changing demand.

Design/methodology/approach

The authors first use a modified Nerlovian supply response model using secondary data to identify the major price and non-price factors influencing the supply of pigeon pea, black and green gram in the major pulses growing states in India. Second, using primary qualitative data the authors map the pulses value chain from farm to retail to identify the how proportional and fixed transaction costs (FCTs) influence market participation of pulses growers and limit the transmission of price and quality information.

Findings

The supply response model shows some positive influence of price on area allocation for pigeon pea and black gram and some negative effects of yield and price increase of competing crops on pigeon pea acreage. However, for the most part, the area of Kharif pulses is inelastic to prices in the long run. Irrigation, rainfall and yields in the lag year are shown to have a significant influence on area allocation for pulses. The market study reveals that low yields, low landholding size and geographical disadvantages of high agro-climatic risk and poor connectivity hinder market access of pulses farmers relative to other crops. Market power in favor of buyers and poor price and quality information is a disadvantage to sellers, influencing their ability to participate in markets.

Research limitations/implications

A quantitative study would be required to identify the magnitude of farm and market-level transaction costs.

Originality/value

This study helps to understand the supply response of pulses and gives suggestions to direct policy to rectify this.
