The automated fault detection and diagnostics (AFDD) of heating, ventilation, and air conditioning (HVAC) using data mining and machine learning models have recently received substantial attention from researchers and practitioners. Various models have been developed over the years for AFDD of complete HVAC or its sub-systems. However, HVAC complexities, which partly have roots in its close coupling nature and interrelated dependencies, mean that understanding the relationship between faults and the suitability of the techniques remains an unanswered question. The literature analysis and interactive visualization of the data collected from the past implementation of AFDD models can provide useful insight to further explore this question by applying artificial intelligence (AI). Association rule mining (ARM) is deployed by this paper, using the frequent pattern (FP) growth algorithm to generate frequent fault sets for most common HVAC faults from the body of AFDD models developed in the literature to represent the status quo. A new model is developed for common HVAC faults and the techniques most frequently used to detect and diagnose them. A recommender system is developed using the ARM model to extract knowledge from the body of knowledge of HVAC data-driven AFDD in the form of rule-sets that reflect the associations. Findings of this review paper can significantly help civil and building engineers, as well as facility managers, in better management of building HVAC systems.

Abstract This article seeks to contribute to the existing body of knowledge about the relationship between political discourse and national identity. 1Malaysia, introduced in 2009 by Malaysia’s then newly appointed 6th Prime Minister Najib Razak, was greeted with expectation and concern by various segments of the Malaysian population. For some, it signalled a new inclusiveness that was to change the discourse on belonging. For others, it raised concerns about changes to the status quo of ethnic issues. Given the varying responses of society to the concept of 1Malaysia, an examination of different texts through the critical paradigm of CDA provide useful insights into how the public sphere has attempted to construct this notion. Therefore, this paper critically examines the Prime Minister’s early speeches as well as relevant chapters of the socioeconomic agenda, the 10th Malaysia Plan, to identify the referential and predicational strategies employed in characterising 1Malaysia. The findings suggest a notion of unity that appears to address varying issues.

Scholars have increasingly noted mechanisms by which religion may be detrimental to one’s health, but few have explored how individuals understand linkages between religious involvement and adverse health. Using data gathered from telephone interviews with Protestants and Catholics in North Carolina and South Carolina, we explore how individuals understand the role of religious moral failure in shaping health consequences. When asked to discuss the relationship between religion and health, 23 respondents described experiences or beliefs regarding how failing to meet the expectations of their religion corresponded with a range of reduced mental and physical health outcomes. Findings underscore the need for additional research on the role of religious involvement and life course experiences in shaping expectations that health declines result from moral failure.

This chapter examines the role of green transformational leadership on promoting green organizational behavior. Green transformational leadership has been found to be influencing green organizational behavior. The study uses content analysis and website analysis. Nedbank is used in the chapter as an archetype of an organization with a green transformational leadership which has influenced green organizational behavior. Four characteristics of green transformational leadership namely idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration were used. The leadership engages its customer and rewards them for green behavior which is important for intellectual stimulation and motivating their employees. The study contributes to the body of knowledge on green transformational behavior by confirming the relationship. The chapter recommends that more trainings and educational awareness on green values be provided to the management so that ultimately this are emulated and practiced by their employees.

AbstractA commonly held perception is that an elite graduate degree can “scrub” a less prestigious but less costly undergraduate degree. Using data from the National Survey of College Graduates from 2003 to 2017, this article examines the relationship between the status of undergraduate degrees and earnings among those with elite postbaccalaureate degrees. Few graduates of non-selective institutions earn postbaccalaureate degrees from elite institutions, and even when they do, undergraduate institutional prestige continues to be positively related to earnings overall as well as among those with specific postbaccalaureate degrees including business, law, medicine, and doctoral. Among those who earn a graduate degree from an elite institution, the present value of the earnings advantage to having both an undergraduate and a graduate degree from an elite institution generally greatly exceeds any likely cost advantage from attending a less prestigious undergraduate institution.

A scheme is proposed as a basis for soil fertility studies in areas where little information is available. The first stage consists of sampling the area on a grid and determining the patterns of variation in the status of those nutrient elements likely to be deficient. These patterns are then compared with intensity patterns of environmental (including edaphic) variables. Where the two sets of variables can be quantified, regression analysis may be used to estimate the closeness of the relationship ; otherwise the relationship must be assessed visually from the degree of conformity between patterns. Those environmental variables that relate, causally or otherwise, to the distribution of components of chemical fertility are identified by strong correlations. Information so gained may be used in subsequent agronomic studies, both as a guide to number and location of field plots and as a framework for studies in soil chemistry and pedology. The scheme is illustrated using data derived from studies on the Dorrigo Plateau of New South Wales. Factors relating closely to phosphorus, sulphur, molybdenum, and nitrogen distribution were identified. In no case could one factor be used to predict the adequacy of all nutrients.

Business model innovation (BMI) is one of the key activities, which has to be continuously undertaken in every enterprise to sustain competitiveness in today’s digital economy. Although the interest in business models (BM) has risen significantly since the late 1990s, little is known about BMI practices in small- and medium-sized enterprises (SMEs), representing a majority of enterprises in the European market. Our study addresses this research gap and focuses on the investigation of drivers and outcomes of BMI in SMEs. A partial least squares path modeling (PLS-PM) method was used to empirically test the model using data collected in 2017 from 71 SMEs in Slovenia. Results have shown that the innovativeness of enterprises and their business environment has a positive impact on the level of BMI activities in the enterprises. However, this is not the case of fast developing and rapidly changing information technology. In addition, the results show that the level of BMI has a positive impact on BMI outcomes and further on overall business performance. The results contribute to the body of knowledge in the field of BMI activities in SMEs and offer useful insights to SMEs that intend to innovate their business model(s) and government to create a supportive environment.

Recent literature reveals the increasingly important role of Information and Communication Technologies (ICT) within innovation in services. This paper aims at outlining how scholars have conceptualized and defined the relationship between ICT and innovation in services so far, by analysing the fragmented body of knowledge available on the topic, to strengthen the research area as field of study and support its progress. The results of the literature review were derived through a concept-centric analysis of the existing research on ICT and innovation in services. The outcome of the literature review is a conceptual typology that organizes and summarizes the body of knowledge on ICT and innovation in services, and reveals the critical knowledge gaps along with an agenda for future research. The main contribution of this work resides in having organized existing literature on the relationship between ICT and innovation in services into a conceptual typology. The conceptual typology outlines the three main aspects of the link between ICT and innovation in services: the integration of organizational and innovation processes; the cooperation among internal and external agents; and the self-reinforcing innovation mechanism that characterizes ICT as a product.

Over the last decades, sustainability-related topics have increased their relevance to infrastructure development. Researchers have conducted studies analyzing the relationship between Public-Private Partnerships (PPPs) and sustainability. However, despite the PPPs have been recognized as a relevant factor for sustainable development, no bibliometric analyses have been conducted studying the relation between PPPs and sustainability. This paper introduces a comprehensive understanding of the body of knowledge of the nexus between sustainability and PPPs, their evolution, and the connections of their main topics. This analysis allows for integrating disperse studies within a comprehensive PPP-sustainable framework. The Network Analysis unraveled that the significance of sustainability within PPPs has grown over time evolving from traditional developed English-speaking countries to developing countries. Overall, the PPP research agenda has evolved from road infrastructure dominance driven by a public sector’s perspective of social welfare to increasing types of infrastructure driven by economic and environmental performance yet remaining to strengthen the latter.

Despite sport rebranding becoming an emerging topic for both academia and industry, there has been a limited number of investigations on how sport rebranding influences sport fans. The aim of this study is to investigate how sport rebranding in the form of logo redesign influences fan loyalty. Through an experimental approach, the results indicate that attitude toward rebranding plays a significant role in fan response when sport rebranding occurs. Additional findings suggest that logo evaluation partially mediates the relationship between logo change and brand loyalty. This study makes significant contributions to the body of knowledge on sport rebranding by revealing how fans’ attitudes toward rebranding affects brand loyalty. The proposed model suggests directions for future sport rebranding research, and the paper provides implications for how sport marketers can use various rebranding strategies to improve rebranding outcomes and diminish negative responses from sport fans.
