Abstract
Purpose
The application of condition-based maintenance on selected equipment can allow online monitoring using fixed, half-fixed or portable sensors. The collected data not always allow a straightforward interpretation and many false alarms can happen. The paper aims to discuss these issues.
Design/methodology/approach
Statistical techniques can be used to perform early failure detection. With the application of Cumulative Sum (CUSUM) Modified Charts and the Exponentially Weighted Moving Average (EWMA) Charts, special causes of variation can be detected online and during the equipment functioning. Before applying these methods, it is important to check data for independence. When the independence condition is not verified, data should be modeled with an ARIMA (p, d, q) model. Parameters estimation is obtained using the Shewhart Traditional Charts.
Findings
With data monitoring and statistical methods, it is possible to detect any system or equipment failure trend, so that we can act at the right time to avoid catastrophic failures.
Originality/value
In this work, an electro pump condition is monitored. Through this process, an anomaly and four stages of aggravation are forced, and the CUSUM and EWMA modified control charts are applied to test an online equipment monitoring. When the detection occurs, the methodology will have rules to define the degree of intervention.

Abstract
Purpose
This study aims, first, to understand consumers’ perception of chefs as human brands (i.e. study one). Second, tests were run to assess the validity of a new conceptual model of the relationships between the factors of chef image, luxury restaurant image, both images’ congruity and consumers’ hedonic and novelty experiences and happiness and well-being (i.e. study two).
Design/methodology/approach
The first qualitative study involved using Leximancer software to analyse the data drawn from 43 interviews with luxury restaurant clients. In the second quantitative study, 993 valid survey questionnaires were collected, and the proposed model was tested using structural equation modelling.
Findings
The results reveal that consumers perceive chefs as human brands and the associated narratives include both performance- and popularity-based characteristics. The findings support the conclusion that individuals give great importance to chefs’ image and the congruence between chefs and their restaurant’s image. In addition, luxury restaurant image only affects novelty experiences, and both hedonic and novelty experiences have a positive effect on customers’ happiness and well-being.
Research limitations/implications
This research focused on Portuguese luxury restaurants. The consumers’ happiness and well-being needs to be replaced by other outcomes to confirm if the model produces consistent results.
Practical implications
The results should help luxury restaurant managers understand more fully which pull factors are valued by their clients and which aspects contribute the most to their pleasure and welfare.
Originality/value
This study adds to the extant literature by exploring consumers’ perceptions of chefs as human brands and the role these chefs’ image play in customers’ luxury restaurant experiences and perceived happiness and well-being.

Abstract
This chapter probes the issue of capital mobility and its implications in the context of the globalization of the fresh fruit sector. In particular, it explores the relationship between productive capital and labor in two different Latin American regions: the Northeast of Brazil and Patagonia in Argentina. Employing a comparative approach, it studies the impact that the insertion of local production into global circuits has on local firms and labor. These relatively culturally and geographically distant locations are affected by similar phenomena created by the globalization of agrifood. Relevant among then are the marginalization of labor and a weak labor structure. While there has been the growth of local firms, this growth has not erased important weaknesses.

Abstract
At the outset, though, and before brief summaries of each of these cases are presented, it is important to underscore two key points that guide the organization of the entire volume. First, capital mobility is a complex phenomenon that assumes various forms as different types of capitals move at different velocities. Second, capital mobility is a necessary and irreplaceable component of capitalism. As for the first aspect, we will consider three types of capital: financial capital, productive capital, and labor. Obviously, these three forms of capital are endowed with different features that affect their behaviors and their ability to move through time and space. While all these three forms of capital share the common requirement that they need to be utilized in increasingly accelerated manners if capital accumulation had to expand, they also display tendencies that favor financial and productive capital and subordinate labor. If effect, the subordination of labor to financial and productive capital is one of the primary characteristics of globalization and one item that allowed the rapid expansion of capital accumulation over the last two decades.

Abstract
Purpose
A citation analysis was conducted on publications of the faculty from the University of Florida (UF), Department of Chemical Engineering. The analysis was undertaken to gain a better understanding of the research programs in chemical engineering and to examine how the library aligns its research support through resources and journals to the needs of the department’s faculty. The analysis focused on where the faculty published, their most frequently cited resources, and what growth patterns were evident. The paper aims to discuss these issues.
Design/methodology/approach
Five years of publications (2011-2015) by the UF chemical engineering faculty were included in the analysis. Web of Science was used to compile a list of the articles published in peer-reviewed journals as well as the citations.
Findings
Faculty were found to have published 279 articles in the last five years, with 27 percent of those articles shared by five journals, and with an average impact factor of 3.459. Applied Physics Letters was the most cited journal and Advanced Materials had the highest impact factor of 17.493. The library owned 95 percent of the publications in which faculty published their work and at least 82 percent of the resources cited in their publications. The pattern of the publications was not consistent and the most articles in one year (69) were published in 2013.
Originality/value
Since this study focused on the current patterns regarding where the faculty are publishing and citing, it should be a fairly accurate indicator of their future needs. Therefore, the study impacts decisions regarding future directions by enabling the library to maintain a high-quality collection for the faculty.

Abstract
Purpose
Collaborative consumption emerges from social practices such as sharing, lending and gifting. It is becoming more common among consumers, boosted by the internet, which facilitates the collaboration process with both strong and weak ties. This paper aims to examine collaborative consumer experience, delving into the factors that contribute to the adoption and the perceived benefits of this alternative form of consumption.
Design/methodology/approach
A total of 12 phenomenological interviews were conducted o explore the theme from an individual perspective, attested by the consumers’ narratives and experiences.
Findings
The results highlight collaborative consumption as being influenced by family practices, social relations and the current economic scenario. Also, noteworthy is the evidence that collaborative consumption enables consumers to select from a more diversified portfolio of products and services, especially the ones featured by the internet and social media. Consumers perceive financial, emotional, social, environmental and increased consumption benefits, depending on their practices of collaborative consumption, and also on their role as providers, consumers or exchangers.
Originality/value
Through the phenomenological approach, based on individual reports of experiences related to collaborative consumption, it was possible to highlight some aspects relevant to better understanding the behavior of collaborative consumers.

Abstract
Purpose
The purpose of this paper is to investigate the relations in the Marketing/Operations interface through the analysis of data of the operational reality of a Brazilian company with a low technological intensity. The study aims to quantify and determine the impacts of marketing decisions on delivery performance and on flexibility of the operations area.
Design/methodology/approach
A longitudinal case study was conducted and the variables used in the model were derived from established theories and were evaluated with artificial neural networks. The case of a food manufacturing company was selected to reflect the relations in the marketing/operations interface of a low technological intensity enterprise.
Findings
The results show that the decisions on Place/Channel, Price and Product dimensions of marketing exert a significant impact on flexibility and delivery performance of the operation area.
Research limitations/implications
The findings of the case study cannot be generalised and the outcomes are specific to just one firm. However, the approach lends itself to replication, particularly within low technological intensity companies.
Originality/value
Prior studies have focussed on coordination among functional areas as marketing and operations at higher levels of abstraction. The study contemplate empirical propositions through the data analysis of a company with a low technological intensity that can be used to improve managers' decisions and alignment in the Marketing/Operation Interface.
