Abstract

In his March 1986 article in Newsweek, Russell Watson exposed “Queen Imelda” Marcos's life of indulgence as the Philippines' First Lady in the opening paragraph:Three thousand pairs of shoes, size eight and a half. Five shelves of unused Gucci handbags, still stuffed with paper, price tags still attached. Five hundred bras, mostly black, and a trunk full of girdles, 40 and 42 inches around the hips. Huge bottles of perfume, vats of Christian Dior wrinkle cream, a walk-in-safe littered with dozens of empty jewelry cases. When the palace of Ferdinand and Imelda Marcos was opened to the public as a museum last week, foreigners and Filipinos alike gawked at what the former First Lady had left behind. “It was the worst case of conspicuous consumption I have ever seen,” said an American visitor, Rep. Stephen Solarz. “Compared to her, Marie Antoinette was a bag lady.” (Watson, 1986, p. 14)

Abstract

Purpose

Renewable generation is a main component of most hybrid generation systems. However, randomness on its generation is a characteristic to be considered due to its direct impact on reliability and performance of these systems. For this reason, renewable generation usually is accompanied with other generation elements to improve their general performance. The purpose of this paper is to analyze the power generation system, composed of solar, wind and diesel generation and power outsourcing option from the grid as means of reserve source. A multi-objective optimization for the design of hybrid generation system is proposed, particularly using the cost of energy, two different reliability indexes and the percentage of renewable energy as objectives. Further, the uncertainty of renewable sources and demand is modeled with a new technique that permits to evaluate the reliability quickly.

Design/methodology/approach

The multi-state model of the generators and the load is modeled with the Universal Generating Function (UGF) to estimate the reliability indexes for the whole system. Then an evolutionary algorithm NSGA-II (Non-dominated Sorting Genetic Algorithm) is used to solve the multi-objective optimization model.

Findings

The use of UGF methodology reduces the computation time, providing effective results. The validation of reliability assessment of hybrid generation systems using the UGF is carried out taking as a benchmark the results obtained with the Monte Carlo simulation. The proposed multi-objective algorithm gives as a result different generators combinations that outline hybrid systems, where some of them could be preferred over others depending on its results for each independent objective. Also it allows us to observe the changes produced on the resulting solutions due to the impact of the power fluctuation of the renewable generators.

Originality/value

The main contributions of this paper are: an extended multi state model that includes different types of renewable energies, with emphasis on modeling of solar energy; demonstrate the performance improvement of UGF against SMC regarding the computational time required for this case; test the impact of different multi-states numbers for the representation of the elements; depict through multi-objective optimization, the impact of combining different energies on the cost and reliability of the resultant systems.

Abstract

Purpose

The purpose of this paper is to offer an economic analysis of the convenience store format and the various categories thereof for the Spanish case in the period 1998‐2004.

Design/methodology/approach

Using secondary information sources, the analysis methodology is based on economic indicators of the output level and on the calculation of output/input ratios.

Findings

The results show a positive evolution of the format regarding both the sales volume and the number of establishments, a high‐concentration rate in the sector and a positive trend of the productivity ratios. However, differences are observed between distribution groups or chains, as well as between the various analysed types.

Research limitations/implications

The analysis uses secondary data, namely generally accepted apparent economic indicators that cannot reflect the entire reality of the market. The analysed market is the Spanish market. So, more effort of analysis is needed with primary data and it emerges the convenience of that the competent authorities provide more statistical information about the sector.

Originality/value

This work provides knowledge about management decisions by retailers regarding a specific format (the convenience format), which is emerging in some categories and is mature in others. This research covers a lack of both conceptual and empirical studies that are targeted at understanding these formats and at analysing their current and future situation. The most specific contribution is the focus on a specific format not analysed previously, from the point of view of economic ratios including an approximation to marketing productivity, a priority area of study in this area of knowledge. The analysis performed allows verifying the positive evolution shown by the format in recent years. It also reflects upon the fact that it would be advisable for competent authorities to publish periodic statistics on the global format and on its types.

Abstract

Purpose

The purpose of this study was the development and the nutritional, physical-chemical and sensorial characterization of probiotic and synbiotic sorbets elaborated with jussara pulp (Euterpe edulis), Lactobacillus spp. and polydextrose.

Design/methodology/approach

Five formulations of jussara sorbets (one control, two probiotics and two synbiotics) were produced and evaluated according to their centesimal composition, pH, soluble solids, instrumental color, overrun, apparent density, sensory acceptability and purchase intent.

Findings

All sorbets exhibited low calorific value, with no difference between them (p =0.96). The synbiotic samples (S3 and S5) showed the higher carbohydrate (30.4 and 30.2 per cent) and crude fiber content (0.4 and 0.5 per cent). Regarding to sensory acceptance, the probiotic samples (S2 and S4) presented greater global acceptability (averages acceptance 6.4 and 6.6, respectively) while the polydextrose samples (S3 and S5) showed low values (5.9 for both samples), although this prebiotic was able to increase the overrun to values above 40 per cent.

Practical implications

The functional jussara sorbets are a promising possibility for diversification of the probiotic foods already offered. The combination of its probiotic, prebiotic and bioactive properties can provide technological improvement and superior nutritional quality, with good sensorial acceptance. Likewise, jussara pulp showed nutritional properties favorable to its application in the food industry, which can help preserve its endangered palm tree.

Originality/value

The probiotics and synbiotics jussara sorbets showed to be adequate as a lactose-free and low-calorie functional product, with high nutritional, commercial and ecological value. Also, it was possible to notice that while the addition of probiotics improved the sensorial acceptance of jussara sorbets, polydextrose raised the technological quality by increasing its overrun.

Abstract

Purpose

The characteristics of a particular organizational culture may affect performance in achieving the objectives of international joint ventures (IJVs), a type of partnership that is often used in international business relations between developed and emerging countries. The purpose of this paper is to analyse whether the underlying dimensions that characterize organizational culture in these countries may affect firms’ performance, specifically their competitiveness, effectiveness and efficiency.

Design/methodology/approach

The survey conducted for this study was addressed to Spanish-Moroccan IJVs trading in Morocco. The research hypotheses were tested using multivariate analysis techniques (exploratory factor analysis and linear regression model).

Findings

Based on information provided by the CEOs of Spanish-Moroccan IJVs between small- to medium-sized firms, the present study shows that levels of competitiveness, effectiveness and/or efficiency in these organizations are influenced by the involvement of staff in management, the degree of centralization of decision taking and the firms’ emphasis on results or on procedures.

Practical implications

This research contributes to the knowledge of the main factors related to the organizational culture of joint ventures that influence competitiveness, effectiveness and efficiency achieved.

Originality/value

The value provided by this research lies in the sample examined, in its focus on a very common type of partnership between SMEs, which has been little studied previously, and in the fact that the results obtained are extensible to other realities, such as partnerships between European companies and those from countries with similar characteristics (located in Africa or in countries where an Arab culture prevails).

Abstract

Purpose

Broad-spectrum cephalosporin resistance is rapidly increasing in Escherichia coli, representing a food safety problem. The purpose of this paper is to characterize eight extended-spectrum-ß-lactamase (ESBL) and acquired AmpC ß-lactamase-producing E. coli isolates and virotypes associated, obtained from chicken and pork food samples in Puebla, Mexico.

Design/methodology/approach

Samples (36 from chicken and 10 from pork) were cultured on Levine agar plates supplemented with cefotaxime (2 mg/L) for isolation of cefotaxime-resistant (CTXR) E. coli. CTXR-E. coli isolates were detected in 33 of 46 samples (72 percent), and one isolate/sample was characterized (28 from chicken and 5 from pork), for ESBL production, phylogenetic group, sequence typing, resistance and virulence genes by PCR and sequencing.

Findings

Results showed 16 ESBL-E. coli (35 percent) (12/16 belonging to phylogroup B1) and 8 CMY-2-E. coli (17 percent). ESBL detected were as follows (number of isolates): CTX-M-2 (8); CTX-M-1 (2); CTX-M-15 (1); SHV-2a (4) and TEM-52c (1). In total, 20 different sequence types (STs) were identified among the ESBL- or CMY-2-producing E. coli strains, which included four new ones. The CTX-M-15 β-lactamase was detected in one E. coli ST617-ST10 Cplx-B1 strain that also carried ibeA gene. One CMY-2-positive strain of lineage ST224-B2 was detected and it carried the qnrA1 gene.

Originality/value

In this study, a ST131-based virotyping scheme for strains from food of animal origin was established since this kind of strains constitutes an important vehicle of virulent ESBL- and CMY-2-producing E. coli isolates, which could be transmitted to humans by direct contact or through the food chain.
