1. Introduction

American Airlines was the first company in the airline industry to launch a frequent-guest program in 1981 to reward travelers for their loyalty to the brand. In the lodging industry, InterContinental took the lead and became the first hotel company to offer a loyalty program (Dekay et al., 2009). In today’s business world, most hotels have established their own loyalty program, which has gradually become a provision that hotel guests would expect. In 2015, the loyalty programs of major hotel groups had more than 300 million members (Peltier, 2016). While the impressive number shows the popularity or attractiveness of loyalty programs, the real active members are far fewer than this number (Peltier, 2016). For instance, La Quinta Returns program has 11 million members, yet only 25.5 per cent were active members in 2015 (Peltier, 2016). The surprising contradiction between the popularity of loyalty programs and the lagging number of active members inspired the researchers of the present study to ask the research question of whether it is operationally and financially beneficial for hotel companies to invest in loyalty programs. The benefits for hotels to offer loyalty programs to their guests can be manifested in profitability, share of wallet, willingness to pay more, word-of-mouth (WOM) and electronic WOM (Kandampully et al., 2015). First, through initiating loyalty programs, companies can directly gain profits from customer repurchase behavior (Bolton et al., 2000; Keh and Lee, 2006). Moreover, using loyalty programs to manage current customers can reduce the cost needed to attract new customers, thereby indirectly increasing the profitability. Second, the term share of wallet describes how customers choose to allocate their monetary resources among different products of different brands (Evanschitzky et al., 2012). It is important for companies to understand how their customers make purchase decisions among various products or services. Loyal customers tend to stay with one company and build emotional commitment with it (Evanschitzky et al., 2012). Closely related to sharing of wallet is the third benefit of loyalty program – willingness to pay premium. Once loyalty is built with a company, loyal customers are less sensitive to the premium price charged by the company and are more likely to perceive greater values from the products or services provided by this company (Dowling and Uncles, 1997; Reichheld and Sasser, 1990). In addition, customer loyalty has an impact on customer behavior; in that, loyal customers tend to actively spread positive WOM, whether in person or through electronic media, thus playing an important role of brand ambassadors (Kandampully et al., 2015; Jeon and Jeong, 2017).

Introduction

In recent years, environmental concerns have put pressure on practitioners to adopt various environmental initiatives. This trend has motivated a considerable body of research to examine the relationship between green initiatives, green performance, and business performance (Aragon-Correa, 1998; Klingenberg and Geurts, 2009; Liet al., 2017; Miroshnychenko et al., 2017; Ngniatedema and Li, 2012; Rothenberg et al., 2001; Seroka-Stolka, 2016). In their early work related to green initiatives, scholars have mostly focused on issues such as green product and process development, lean and green operations management, remanufacturing, logistics and closed-loop supply chains (Angell and Klassen, 1999; Klingenberg and Geurts, 2009). The majority of empirical studies in these early works have focused on the manufacturing sector in the USA (Kassinis and Soteriou, 2003; Klassen and McLaughlin, 1996; Kleindorfer et al., 2005) with very few on the service sector (Foster et al., 2000; Goodman, 2000; Judge and Douglas, 1998). Of these studies, very few found significant evidence that green practices are related to a firm’s financial performance. Besides studies that focus on green practices and sustainability performance of firms based in the USA (see e.g. Li et al., 2017; Seroka-Stolka, 2016), researchers have begun to look beyond US firms (Christmann and Taylor, 2002). This observation in itself demonstrates the rapidly increasing importance of these topics on a global scale and may justify the synthesis of the literature by Goyal et al. (2013) on environmental-related studies for a 19 years’ span (1992-2011). For the study period 1992-2010, the maximum number of articles related to sustainability issues is based in the USA, the UK, Spain, and Germany, and in other developing countries such as India (Goyal et al., 2013). In the literature, there is some discussion on the links between green initiatives, green performance, and financial performance within the context of corporate social responsibility (CSR), in which the authors use data from firms based in a particular country. Several examples can be found in early works, such as Aras et al. (2010) investigated the Istanbul Stock Exchange 100 index companies and their CSR policy, which is measured by the extent of social and environmental disclosures, and financial indicators. They did not find significant evidence on the CSR-financial performance link for Turkish firms. In examining the link between CSR and firm value, Lima Crisóstomo et al. (2011) found a significant negative impact of environmental action on firm value for companies based in Brazil. A similar study was conducted by Usman and Amran (2015) using data from 68 companies listed on the Nigeria Stock Exchange.

1. Introduction

This paper investigates selected corporate governance (CG) attributes and financial reporting lag and their impact on financial performance of listed firms in Ghana. The International Accounting Standards Board (IASB, 2010) Framework for the Preparation and Presentation of Financial Statements states that there are some qualitative characteristics that make the information provided in financial statements useful to users. These qualitative characteristics are relevance, faithful representation, comparability and understandability. According to the IASB (2010) relevance and faithful representation are the fundamental qualities, while comparability and understandability are enhancing qualities. Timeliness is an auxiliary aspect of relevance. Timeliness means having information available to decision-makers, before it loses its capacity to influence decisions. If information is either not available when it is needed, or becomes available so long after the reported events that it has no value for future action, it lacks relevance and is of little or no use (IASB, 2010). Timeliness alone, cannot make information relevant, but a lack of timeliness, can rob information of relevance it might otherwise have had. Timeliness provides a platform for market integrity and efficiency to ensure fairness, efficiency, transparency, protect investors and reduce risk, which will in turn improve financial reporting quality (Al-Ajmi, 2008; Turel, 2010). Prior empirical studies have examined the timeliness (reporting lag or delay) of corporate reporting and its determinants; (Apadore and Mohd Noor, 2013; Sharinah et al., 2014; Yadirichukwu and Ebimobowei, 2013; Ilaboya and Iyafekhe, 2014; Mohamad-Nor et al., 2010; Shukeriand Islam, 2012), examined financial reporting lag and audit committee characteristics timeliness and relevance of financial reporting; (Ohaka and Akani, 2017), examined company characteristics and timeliness of financial reporting. The objective of this paper is to investigate how selected CG attributes and financial reporting lag affect the financial performance of listed firms in Ghana. This paper differs from earlier research on timeliness of reporting and CG as it tests the influence of timeliness of reporting and board attributes on firm performance using only accounting information. Generally, there are two types of financial reporting lag: audit report lag (ARL); and management report lag. ARL is the period from a firm’s year-end and the audit report date while management report lag is a period between the end of the fiscal year of firms and the publication of the audited financial reports (Zaitul, 2010). Financial reporting lag in this study refers to ARL, i.e. the length of time between the fiscal year-end of a company and the date of the auditor’s report. The board attributes used are board size, proportion of independent directors, board gender diversity, independent audit committee, institutional ownership and block ownership concentration. Firm performance is measured using two accounting ratios; return on equity (ROE) and return on assets (ROA). Accounting-based measures are preferable in the context of CG study because they reflect the ability of the management in adding value to the firm. Higher ROA and ROE ratios are indication that the firm’s CG mechanisms are highly effective (Mishra and Kapil, 2017).

1 Introduction

Data are vulnerable and need utmost security when they are getting transferred from source to destination. Encryption is one of the most formidable ways to keep our data and information safe between two endpoints. It makes data impenetrable and unread-able, so even it ends up getting in wrong hands it is mostly useless [1]. DNA (deoxyribonucleic acid) is a genetic information carrier from parent organisms to the newly forming organism. The methodologies of encryption in which compo-nents of DNA are used to hide plain text from eavesdropper or unauthorized users in the network come under the study of DNA cryptography [2]. In DNA cryptography, the four chemical bases of DNA namely adenine (A), guanine (G), cytosine (C) and thymine (T) has so far majorly been used in addition to cryptographic algorithms but with advancement in the study of other components like Amino acids are also brought into the play [3]. Considering ‘ATGC’ to be a code we can have 24 combinations of it like ‘CTAG’, ‘TAGC’ etc. (4! = 24). Although among the 24 combinations only 8 are possible in a real life occasion as ‘A’ can combine only with ‘T’ and ‘C’ combines only with ‘G’ following the properties of DNA [3]. But, here we shall use all the 24 combinations to encrypt our data. This will increase the complexity of detecting patterns in the encrypted text. In the study of cryptography, an image which contains information is converted to an unreadable or unrecognizable form by using algorithms. This field is gaining much popularity as image can carry vital information with them. The capacity of carrying information is also more by an image. In image encryption methodologies, the pixels of original images are either manipulated of information is laid inside the image using the image as a cover to protect the data from undesired receivers [4]. Image encryption enables passing of data over unsecured networks like the internet. Without the correct key, the correct decryption to retrieve the original is a major challenge to high-end super computers [5]. Although image encryption might require more than normal text encryption but it is more formidable. Image encryption plays a vital role in securing the transmission of important government document images, images of military, healthcare and other private images [6]. Section 2 gives a background of work relating to image encryption and DNA cryptography together; Sect. 3 provides the description of proposed algorithm, utility of some of its steps and the entire algorithm; Sect. 4 documents the result analysis and Sect. 5 concludes the paper.

1 Introduction

Visual Cryptography (VC) is a category of secret sharing scheme, proposed by Naor et al. [17], that allows computation-less decoding of secret images. Mainly in a k-out-of-n visual secret sharing (VSS) scheme, a secret image is encoded into n noise-like shares and printed onto transparencies to distribute them among n participants. Secret image can be decoded by just stacking any k or more transparencies. In spite of using infinite computation power, k − 1 or fewer participants can not decode the secret image. Besides the secret sharing, visual cryptography can also be used for number of other purposes including access control, watermarking, copyright protection [5], identification [16] and visual authentication. To demonstrate the working of VSS, consider a 2-out-of-2 VSS (k = 2, n = 2) scheme shown in Fig. 1. Each pixel p of secret binary image is encoded into a pair of black and white subpixels for both shares. If p is white/black, one of the first/last two columns tabulated under the white/black pixel in Fig. 1 is selected randomly so that selection probability will be 50 %. Then, the first two subpixels in that column are alloted to share 1 and the following other two subpixels are alloted to share 2. Independent of whether p is black or white, pixel is encoded into two subpixels of black-white or white-black with equal probabilities. Thus an individual share has no idea about whether p is black or white. The last row of Fig. 1 shows the superimposition of the two shares, If the pixel p is black, the output of superimposition will be two black subpixels corresponding to a gray level 1. If p is white, then result of superimposition will be one white and one black subpixel, corresponding to a gray level 1/2. Hence by stacking two shares together, we can obtain the approximate visual information of the secret image. Figure 2 shows an example of the 2-out-of-2 VSS scheme. Figure 2a shows a secret binary image Isec to be encoded. According to the encoding scheme shown in Fig. 1, each pixel p of Isec is divided into two subpixels in each shares, as shown in Fig. 2b and c. Stacking the two shares leads to the output image shown in Fig. 2d. The decoded image is clearly revealed. There are some contrast loss and the width of the reconstructed image is just twice of the original secret image. The 2-out-of-2 VSS scheme shown above is a special case of the k-out-of-n VSS scheme. A more general model for VSS schemes based on general access structures has been designed by Ateniese et al. in [1]. An access structure is a specified set of all the qualified and forbidden subsets of the shares. The secret image can be decoded by the participants of a qualified subset only. The capabilities of VSS has also been enhanced by allowing gray scale images as secret rather than a binary image [15].

1 Introduction

Smart manufacturing describes the new manufacturing intelligence applied to modern information technologies such as the Internet of Things, cloud computing, and artificial intelligence in the manufacturing process (Tao et al. 2018a, b). Data from various sources is becoming integrated into manufacturing intelligence to improve manufacturing in various ways. A typical example is the wide deployment of sensors in manufacturing to monitor and provide real-time manufacturing data such as temperature, humidity, speed, vibration, and acidity for better decision-making and control of the manufacturing process (Li et al. 2015). Therefore, multiple sensors of different modalities are needed in distributed locations. Wired sensor networks are extensively adopted, but the cost for their installation, testing, maintenance, and shutdown are quite high. In many cases, a wireless sensor network (WSN) is a more attractive alternative because it does not require any fixed infrastructure and can be applied over distributed areas where cabling is costly (Akyildiz et al. 2002). A WSN is composed of sensor nodes and sink nodes. Sensor nodes are responsible for collecting and forwarding data. Sink nodes either analyze data locally or forward data to a base station (Magaia et al. 2015). Each sensor node consists of small devices for sensing, processing, transceiving, and power, and it is able to communicate with other sensor nodes or directly with a base station. A WSN can be regarded as a self-supporting unit, with which unattended operation can be realized (Stankovic 2008). It is mostly applicable where power supplies and cabling are difficult, or in hostile environments that people cannot enter. With the technological developments in cloud computing and Internet of Things, WSNs are becoming even more widely deployed. They have also been used for machine health monitoring (Tiwari et al. 2007), data center monitoring (Wang et al. 2013), and data logging (Saleem et al. 2014) in various industries. Moreover, a WSN can be used for environmental monitoring (Hart and Martinez 2006), remote health care monitoring (Malasinghe et al. 2017), and other monitoring scenarios. Overall, its application in cloud computing and Internet of things and has significant social and economic benefit (Tao et al. 2014, 2011). WSNs have a key difference with the wired sensor network in that the sensor nodes in a WSN rely solely on their own battery, and thus have limited power resources. Moreover, their computing power and storage resources are also limited. As a consequence, reducing the energy consumption of each sensor node is a critical issue for WSNs (Carrabs et al. 2015). Ant colony optimization (ACO) has been used in WSNs to identify shortest paths, and thus reduce the energy consumed by a network. However, the ACO is prone to falling into local optima and converges slowly. We hence propose an improved ACO (IACO) that can be used to construct the sensor node transfer function and pheromone update rule, and adaptively construct a data route using the characteristics of a dynamic network. The major contributions of this paper are listed below. 1. The IACO consumes less energy. 2. The transmission delay is reduced using the IACO. 3. Fewer transmission packets are lost when using the IACO. This paper is organized as follows. Section 2 analyzes the current WSN routing algorithms and their weakness. In Sect. 3, we describe our model and its notation. In Sect. 4, a detailed description of the proposed routing IACO algorithm is given. In Sect. 5, simulation results comparing the proposed algorithm with several other algorithms are presented to show the effectiveness of the proposed method.

1 Introduction

The general assumption of majority of flow-shop applications is that the sequencing of the jobs relies on buffers, otherwise they are considered as intermediate storage between machines. The no-wait flow-shop scheduling problem (NWFSP) with makespan criterion is considered in this paper. In NWFSP, each job has to be processed from the first machine to the last without any interruption and the job sequence is unique on all machines. In addition, each machine can handle no more than one job at a time and each job has to visit each machine exactly once. Therefore, the start of a job on the first machine may be delayed in order to meet the no-wait requirement. Given that the release time of all jobs is zero and set-up time on each machine is included in the processing time, the no-wait flow-shop problem is to schedule jobs that minimize the makespan over all jobs. The no-wait flow shop scheduling problem has important applications in modern industry. It has an extensive background in industrial applications, including steel production, mining, logistics, chemical industry and food processing. For example, in steel factories, to avoid cooling and defects in steel, the liquid steel undergoes a chain of operations such as molding into ingots, unmolding, and soaking. Similarly, in the food processing, the canning operation must be operated after cooking operations immediately to ensure freshness (Hall and Sriskandarajah 1996). A comprehensive survey on the research and application of no-wait flow-shop scheduling problem can be found in Hall and Sriskandarayah’s review paper (Hall and Sriskandarajah 1996). In addition, Bagchi et al. (2006) showed that it can be transformed into the asymmetric traveling salesman problem (ATSP) and presented some no-wait and blocking scheduling models. In the operation research literature, many elegant mathematical models and methods have been developed to deal with the real-world problems. Some exact approaches have been proposed to unravel the problems optimally that have the limitation of solving only small-sized problems. On the other hand, heuristics which are based on polynomial time algorithms are the most suitable methods for solving large scheduling problems. In general, heuristics attain good solutions in a reasonable time interval. Additionally, in the recent years meta-heuristics with techniques such as bee colony algorithm (Khorramizadeh and Riahi 2015), genetic algorithm (GA) (Guo et al. 2005), memetic algorithm (MA) (Frutos and Tohme´ 2013), particle swarm optimization (PSO) (Marinakis et al. 2009), Electromagnetism-like Mechanism (SEM) (Bonyadi and Li 2010), and ant colony optimization (ACO) (Riahi and Kazemi 2015) have been developed to generate competitive results for many combinatorial optimization problems. In the recent years, several ant colony algorithms have developed for various kinds of problems including the scheduling problem. Kashan and Karimi (2008) proposed two ACO algorithms with two different visibility functions for total weighted tardiness single machine environment with formation of processing batches. To minimize total completion time in a no-wait two-machine flow-shop, Shyu et al. (2004) designed some specific features including a heuristic for initializing the initial pheromone, a hybrid state transition rule and a hybrid local search. Li et al. (2011) dealt with the minimization of the sum of completion time in a sequence-dependent setups permutational flowshop. The authors used a timelimited dynamic programming algorithm to perform a post-optimization strategy. Mirabi (2011) proposed an ant colony optimization technique for the sequencedependent flowshop scheduling problem.

Introduction

With increasingly uncertain and volatile business environments, strategic flexibility, which refers to firms’ ability to reallocate and reconfigure their organizational resources, processes, and strategies to deal with environmental changes (Zhou and Wu, 2010), is a key business imperative (Sambamurthy et al., 2003; Chen et al., 2014). Firms’ chances of survival in volatile marketplaces, global competition, shortened product life cycles, and customer pressures for tailored offerings depend largely on their ability to adapt rapidly to environmental changes (Nadkarni and Herrmann, 2010; Zhou and Wu, 2010). Faced with these challenging external demands, firms’ adaptability seems to hinge on their strategic flexibility (Drnevich and Croson, 2013). Information technology (IT) is a key enabler of strategic flexibility, and firms reply on it for automation, cost reduction, and improvement of operational efficiency (Duncan, 1995; Bhatt and Grover, 2005). Beyond supporting tactical and operational impacts, IT is instrumental in helping firms support or transform strategies, business models, and relationships between companies and their partners and customers (Bharadwaj et al., 2013). IT provides companies with advanced computing capacity, information processing and analytic abilities, and stronger empowering capabilities, helping them enter new markets and launch new ways to conduct business. For example, the Chinese mobile-device maker Xiaomi has built a community of fans to collect feedback and recommendations for product designs (McKinsey, 2015). Chemical manufacturers use big data to help farmers monitor crop conditions in real time and customize their offerings to increase farm yields (McKinsey, 2015). IT is needed to support firms’ rapid product development, and collection and dissemination of market, product and process information to respond effectively to unanticipated changes in the business environment. Recent studies posit that IT capabilities (e.g., IT management and IT competencies) help firms to exploit opportunities and reconfigure IT resources to avoid disadvantageous outcomes, demonstrating IT’s key role in attaining and deploying strategic flexibility.1 Extant conceptual frameworks propose several relationships involving IT capabilities, flexibility and firm performance, and recent papers have examined the proposed relationships empirically. For example, Lu and Ramamurthy (2011) provide evidence of the links between IT capabilities and operational and marketing flexibility. Tallon and Pinsonneault (2011) consider the relations between the combination of customer, partnering and operational flexibility, and organizational performance as moderated by environmental volatility. Chen et al. (2014) show that IT capability can improve firm performance by means of process flexibility.

Introduction

Re-emerging Asian countries promise to regain their high level of contributions to world production and trade, and India has the resources to innovate sustainably. The leadership provided by relatively less populous countries such as Japan, Korea, Taiwan, Singapore and Hong Kong has been motivating many countries, including larger ones such as China, India and Iran. Japan may not have the youth of 1964 (hosting the first Olympics in Asia), but has growing maturity of institutions, along with technological and innovation capabilities, to be a role model as it revitalizes for 2020. It will become the first Asian country to host the Olympics twice. From its spectacular successes in engineering (e.g. defence to space; Kalam and Rajan 2002), India is moving ahead on innovations that benefit the masses (e.g. ICT access) or profit businesses internationally (e.g. IT services). Some firms of Indian origin (FIOs) have been trying painstakingly to compete internationally, not only in software services, but also in technology-based emerging industries such as biopharmaceuticals, where cooperative strategies with institutes can be highly fruitful. Higher stages in the competitiveness journey of firms (Momaya 2001) or institutions can demand much higher flexibility (e.g. Sushil 2007) and health for systematic innovation (Krishnan 2010). The capitalist model of economic development that India has embraced depends on the industrial firm as the driver of progress. As cost advantages erode rapidly in the face of intensifying competition (reaching levels of hyper-competition in several markets in India, e.g. automotive, electronics, FMCG, telecom), focal FIOs (FFIOs) will have to discover other sources of competitive advantages or character competence (e.g. Sharma 2016). Flexibility, innovation and vitality can be some of those sources of advantages. Flexibility has been emerging as an important concept that can link functional silos (such as operations, marketing and finance) to provide agility to organizations to cope up with change. The paradigm of ‘strategic flexibility’ came to the forefront of industrial practice, which synthesized the strengths of most of the previous theories of strategic management in a novel way to fill gaps (Sushil 2015, 2016). Strategic flexibility also acts as a predictor of vitality and sustainability of the enterprise (Sushil 2011). Innovation on multiple fronts— from process and product to business model and technological—is becoming important as India aspires to accelerate on competitiveness enhancement and growth. While firms are the key drivers of growth and adapt from many alternate strategies for growth (Ghosh 2010), focal institutes can also play an important role to shape the ecosystem of competitive industries.
