Scientific literature reports scarce evidence of whether Internetbased procurement systems improve the efficiency of State purchases. We propose a methodology to estimate savings in: (i) the centralization of administrative tasks, and (ii) price differentials due to a larger number of contractors and suppliers bidding on contracts. We test our methods with ChileCompra, the Chilean e-procurement agency. During 2007, 885 Chilean State agencies used this system to purchase US$4.5 billion in products and services. Our preliminary results show price reductions of 2.65% and administrative cost savings of 0.28%-0.38% between 2006 and 2007.

The existing business paradigm in the sawmill industry is that improvements are achieved by enhancements at each individual sawmilling plant. The authors investigate a collaborative approach, and propose a model for optimizing production and inventory planning decisions within a system of plants.

The methodology models the sawmill production process in terms of two transformation stages and two inventory stages. The authors then extend the model to account for supply chain decisions consisting of timber transfers among plants. They apply the model at 11 Chilean sawmills to evaluate whether they can benefit from operating in a more integrated manner.

The authors find an opportunity to increase profits by more than 15 percent through a higher utilization of the capacity and a better assignment of production orders.

The study neglects the possibility of exchanging raw material among plants. Also, the findings are derived from a computational simulation, so are estimates, not actual observations.

The study challenged the business paradigm of the company the authors performed the study for. Now, it is implementing the suggested improvements.

An investigation into how a number of sawmilling companies working together can profit from their distinctive competitive advantages, and which proved successful in challenging one company's business paradigms.

The purpose of this study is to provide a comprehensive bibliometric analysis of publications in the Journal of Public Procurement (JoPP) from 2001 to 2021. The study provides insights into trends in publications, prominent publication themes, influential authors, institutions and countries that have prominently been associated with the journal’s journey.

The study used a bibliometric and content analysis approach using the VOSviewer software to develop insights into the trends, structures and patterns in publications in the journal. Data for the study was extracted from the Scopus and Google Scholar databases.

The study established that there has been consistent growth in the number of papers published by the journal within the last two decades. Yearly average publication by the journal stood at 14 papers between 2002 and 2009, with the annual average rising to approximately 18 papers between 2010 and 2021. The trend in publication has been established and identified the influential citations and contributors to the journal. The study has also clustered out the thematic structures in journal’s publications. The prominent and emerging research issues in the public procurement environment needing immediate research attention have been highlighted.

The study is a one-journal bibliometric analysis and subsequently ignores publications on public procurement from other journals.

The findings of this study highlight to the research community the contributions of JoPP to the public procurement discourse and present important avenues for future research agenda.

To the best of the authors’ knowledge, this study is the first bibliometric study for the JoPP, providing detailed bibliometric indexes of the 21-year period of the journal’s publications. The study comprehensively analyses the contributions in the JoPP to assess the trend and scope in publications in the field of public procurement and draws attention to emerging concerns and critical issues of neglect requiring research attention in the journal.

Milton Nascimento is one of the most prolific Brazilian singers and songwriters of all time, an artist who has formed friendships and made songs with a host of Brazilian artists, with international stars from Latin America, and with artists abroad. Milton’s repertoire has made its way into the fabric of musical compilations of Brazilian music for international listeners. Perhaps unbeknownst to these international listeners, Milton, as an Afro-Brazilian artist, reflects a complex and paradoxical relationship to “race” in his music – at times openly touching upon racial themes, even during an area when the government forbade open discussion of racial tension in Brazil – but at times signifying race more subtly, either through subtle references to diversity in Brazil or through the very elements of his music.

Water pipes degrade over time for a variety of pipe-related, soil-related, operational, and environmental factors. Hence, municipalities are necessitated to implement effective maintenance and rehabilitation strategies for water pipes based on reliable deterioration models and cost-effective inspection programs. In the light of foregoing, the paramount objective of this research study is to develop condition assessment and deterioration prediction models for saltwater pipes in Hong Kong.

As a perquisite to the development of condition assessment models, spherical fuzzy analytic hierarchy process (SFAHP) is harnessed to analyze the relative importance weights of deterioration factors. Afterward, the relative importance weights of deterioration factors coupled with their effective values are leveraged using the measurement of alternatives and ranking according to the compromise solution (MARCOS) algorithm to analyze the performance condition of water pipes. A condition rating system is then designed counting on the generalized entropy-based probabilistic fuzzy C means (GEPFCM) algorithm. A set of fourth order multiple regression functions are constructed to capture the degradation trends in condition of pipelines overtime covering their disparate characteristics.

Analytical results demonstrated that the top five influential deterioration factors comprise age, material, traffic, soil corrosivity and material. In addition, it was derived that developed deterioration models accomplished correlation coefficient, mean absolute error and root mean squared error of 0.8, 1.33 and 1.39, respectively.

It can be argued that generated deterioration models can assist municipalities in formulating accurate and cost-effective maintenance, repair and rehabilitation programs.

This chapter reflects upon the main reasons for the universal, deep, and long-lasting impact of the Mexican neozapatista movement during the 25 years of its public life, recuperating not only the immediate reasons but the reasons linked with process in the middle and in the long term. We argue that the neozapatista movement changed the correlation des forces in Mexico in 1994, opening the transition of all indigenous Latin American movements to pass from a defensive and marginal position, to a new offensive and protagonic position. In the general context after 1989 and the fall of the Berlin Wall, the Mexican neozapatism restores hope in social protest and social fight of all the anticapitalistic and antisystemic movements all over the world. With the above basis, it is possible to understand that this Mexican neozapatism was able to define the general agenda of the main demands and targets that were vindicated for the antisystemic movements during the last 25 years, including all the movements of 2011, such as the Spanish Indignados, or the so-called Arab Spring, or Occupy Wall Street, or even the current French movement of the Gilets Jeaunes, among many others. It explains partially the real function of a kind of “avant-garde” of the antisystemic movements all over the world, playing by the Mexican neozapatismo in the last five lusters and even today.

Purpose: This paper presents a review of the current state and potential capabilities for application of robots, artificial intelligence and automated services (RAISA) in hotel companies.

Design/methodology/approach: A two-step approach was applied in this study. First, the authors make a theoretical overview of the robots, artificial intelligence and service automation (RAISA) in hotels. Second, the authors make a detailed overview of various case studies from global hotel practice.

Findings: The application of RAISA in hotel companies is examined in connection with the impact that technology has on guest experience during each of the five stages of the guest cycle: pre-arrival, arrival, stay, departure, assessment.

Research implications: Its implications can be searched with respect to future research. It deals with topics such as how different generations (guests and employees) perceive RAISA in the hotel industry and what is the attitude of guests in different categories of hotels (luxury and economy) towards the use of RAISA. It also shows what is the attitude of different types of tourists (holiday, business, health, cultural, etc.) and what kinds of robots (androids or machines) are more appropriate for different types of hotel operations.

Practical implications: The implications are related to the improvement of operations and operational management, marketing and sales, enhancement of customer experience and service innovation, training and management.

Originality/value: This book chapter complements and expands research on the role of RAISA in the hotel industry and makes some projections about the use of technologies in the future.

This chapter reviews ethical challenges confronting nonprofit administration in relation to organizational managerial practices and leadership behaviors. Through a theoretical model of nonprofit-specific toxic leadership, it reviews the dynamics of destructive leaders, susceptible followers, and conducive environments in cases of unethical and corrupt nonprofit organizational behaviors. It provides a case for prioritizing oversight responsibilities of the board of directors, board supervision, promoting ethical culture in organizational leadership, and implementing policies for addressing destructive and corrupt nonprofit leaders. It reflects on how nonprofit toxic leadership primarily erodes public trust in the nonprofit sector and concludes with practical recommendations for recentering positive behaviors congruent with the nonprofit's social and public good mission.

The term “Brazilian popular music” refers to a varied repertoire of musical styles with a strong connection to local culture. The initiatives of representation of this domain of interest occur through adaptations of generic models and strategies coming from contexts and musical styles that differ from the essential characteristics of the national music. The purpose of this paper is to present a characterization of Brazilian popular music as a conceptual model which supports the communication and analysis of this domain and serves as a reference ontology for various applications in the field of Information Science and others.

To achieve the purpose, a mapping about Brazilian popular music was done from a literature review and a data collection with expert users, based on domain analysis theory. From this characterization, the conceptual model was built using an Ontology Engineering approach. To facilitate understanding, the results were described using a more user-friendly notation.

The paper presents a conceptual model as a first semantic reference on Brazilian popular music that serves (1) to better understand, communicate and analyze the domain of Brazilian popular music and, (2) to supply some semantic aspects not covered by the adaptations that have been proposed on the literature for musical representation.

The paper adds a new perspective to the understanding of Brazilian popular music and open opportunity to explore other repertoires about popular music.
