The purpose of this paper is to use numerical simulations to investigate the energy conversion performance and the flow and temperature structures inside horizontal tubes connected to a vertical manifold channel.

The simulations are performed for different flow rates and inlet temperatures using CFD.

In both the “flowing wind mode” and “upwind mode,” the inlet velocity is not infinitely small under the influence of natural convection; however, such small inlet velocities cannot be achieved in practice and are of no practical significance. In the “flowing wind mode,” the appropriate velocity for achieving high efficiency is 0.01-0.02 m/s. In the “upwind mode,” the appropriate velocity for obtaining high efficiency is 0.1-0.2 m/s. A high inlet temperature can lead to high efficiency; therefore, a large temperature difference and a small flow can be used in actual designs.

The energy conversion performance and flow structures inside evacuated tubular collectors were investigated using CFD for different operating conditions, notably in the “following wind mode” and the “upwind mode.”

A fundamental problem for intelligent manufacturing is to equip the agents with the ability to automatically make judgments and decisions. This paper aims to introduce the basic principle for intelligent crowds in an attempt to show that crowd wisdom could help in making accurate judgments and proper decisions. This further shows the positive effects that crowd wisdom could bring to the entire manufacturing process.

Efforts to support the critical role of crowd wisdom in intelligent manufacturing involve theoretical explanation, including a discussion of several prevailing concepts, such as consumer-to-business (C2B), crowdfunding and an interpretation of the contemporary Big Data mania. In addition, an empirical study with three business cases was conducted to prove the conclusion that our ideas could well explain the current business phenomena and guide the future of manufacturing.

This paper shows that crowd wisdom could help make accurate judgments and proper decisions. It further shows the positive effects that crowd wisdom could bring to the entire manufacturing process.

The paper highlights the importance of crowd wisdom in manufacturing with sufficient theoretical and empirical analysis, potentially providing a guideline for future industry.

The purpose of this paper is to detect abnormal data of complex and sophisticated industrial equipment with sensors quickly and accurately. Due to the rapid development of the Internet of Things, more and more equipment is equipped with sensors, especially more complex and sophisticated industrial equipment is installed with a large number of sensors. A large amount of monitoring data is quickly collected to monitor the operation of the equipment. How to detect abnormal data quickly and accurately has become a challenge.

In this paper, the authors propose an approach called Multiple Group Correlation-based Anomaly Detection (MGCAD), which can detect equipment anomaly quickly and accurately. The single-point anomaly degree of equipment and the correlation of each kind of data sequence are modeled by using multi-group correlation probability model (a probability distribution model which is helpful to the anomaly detection of equipment), and the anomaly detection of equipment is realized.

The simulation data set experiments based on real data show that MGCAD has better performance than existing methods in processing multiple monitoring data sequences.

The MGCAD method can detect abnormal data quickly and accurately, promote the intelligent level of smart articles and ultimately help to project the real world into cyber space in CrowdIntell Network.

Does the history of the bureaucratic system, along with the establishment of the Great Wall during the Ming and Qing dynasties (1368–1911), affect firm behavior across the borderlands of the Great Wall?

The Ming and Qing dynasties built a centralized administrative system in the borderlands on the south side of the Great Wall, in contrast to the “feudal lordship” system on the north side. Employing a regression discontinuity analysis framework with the Great Wall as a geographical discontinuity, we examine the long-run effects of the Great Wall on firms’ earnings management.

Using a large sample of nonlisted firms in the central core frontier region, we show that the earnings management of firms in the region south of the Great Wall is significantly curtailed compared with firms in the north of it, and this effect is more pronounced for non-SOEs. Our findings are robust to a battery of tests to account for alternative explanations.

Overall, by emphasizing the role of institutions, like legal system, shaped in history on firms’ earnings management, this study sheds new light on institutional determinants of firms’ behaviors in earnings information disclosure.

First, we enrich our understanding of the institutional determinants of firms’ financial reporting outcomes. Second, our findings shed new light on the long-term effects of historical ruling styles on modern corporate behavior.

The ideational connections between social democracy and basic income is the theme of this article. Social democracy is not a fixed doctrine, but as a movement it shares some key ideas with the policy of basic income, like solidarity, equal opportunity, freedom and social security. Due to current challenges emerging from waves of digitalisation, globalisation, etc., the support for a universal basic income has taken off, but not among social democratic politicians. The article argues that the social democratic policy of full employment implies an increasingly tough work orientation that is challenging to reconcile with de-commodifying social rights, which has characterized social democratic welfare states. It is further argued that a strict reciprocity-based policy has not proven effective in getting people into work on a permanent basis, and that the current challenges require new policy ideas. Two alternatives are discussed: guaranteed jobs and a basic income. The article argues that the lack of enthusiasm for the last option among social democrats is based on the misconception that a basic income will harm people's motivation to work, their self-respect, the social economy and the principle of justice. The article sheds light on this misconception. In the closing remarks, the proposal for an ‘emergency basic income’ is considered in view of the current global corona crisis.

Yongye Group is a biotechnological enterprise in Inner Mongolia, China. In China, people lack trust in economic transactions due to the transitional state of the economy, especially regarding food safety. To respond to this situation, Wu Zishen, the chairman of the Board of Directors of Yongye Group, was determined to build trust among employees, distributors, farmers, and consumers towards the company. To this end, he started using a creative incentive system with employees and stakeholders: the pay-before-performance incentive system. According to this system, the reward is delivered in advance, contrary to be paid after the fulfillment of the task. This practice is meant to transform employees' work attitude from a passive “being told to work” to a more proactive “I want to work” mentality. When such an incentive system is practiced with customers and external distributors, it sends a message that the company is “treating customers as company employees”, which means that they are trusted as if they were part of the company itself. Wu Zishen also introduced a coherent series of leadership practices that generate a truly proactive culture in the organization.

From this case, students will learn how to create a proactive culture in business organizations and the effect of pay-before-performance on employees' work motivation.

This paper aims to extend the understanding of how real options reasoning (ROR) is associated with downside risk and how a firm’s portfolio (explore and exploit) of investment activities affects managers’ ability to effectively apply ROR in relation to downside risk.

The survey method is used. It is applied to a population of Danish firms, which in 2018 had more than 100 employees. The chief financial officer was the target respondent.

This study finds that a higher level of ROR is associated with lower levels of downside risk. ROR’s association with lower levels of the downside risk is also moderated by the level of relative exploration orientation in a negative direction.

The field of ROR research on downside risk and portfolio subadditivity has been dominated by research focused on multinationality. This paper extends extant literature on ROR by studying ROR as a multidimensional construct of firm action, which is associated with lower levels of downside risk, also when studied outside of a multinationality setting. This is the case when ROR is implemented as a complete system. This paper also applies a framework of exploitation and exploration to show that findings on subadditivity in options portfolios caused by asset correlations extend outside the scope of multinationality and into one of product/service innovation.

This paper aims to elucidate what concepts of encroachment in business-to-consumer markets explain the market share increase of companies with sustainability value propositions. It documents the encroachment field, analyses the practice of ten companies and proposes and defines the additional concept of transparency encroachment.

Semi-structured interviews were conducted with representatives of companies with an increase in customers and market share due to their sustainability value proposition. These were supplemented with secondary data, like documented interviews, sustainability reports and reports on market development. The interview transcripts and secondary data notes were coded using template analysis.

As the literature on encroachment assumes that new value propositions take away market share from incumbents due to advantages for customers, it is questionable whether it can explain how value propositions with advantages for society as a whole can encroach markets. The results of this study show that the dominant forms of encroachment in the current literature – high-end encroachment, low-end encroachment and business model encroachment – can only partly explain encroachment through sustainability value propositions. An additional encroachment form is identified: transparency encroachment.

This research adds greater clarity to what companies do when they encroach markets with sustainability value propositions. Furthermore, the pattern of transparency encroachment is discussed to define the common aspects of this concept and to argue why these aspects are needed for encroachment. It implies that marketing activities should start from the perception that customers are allies – and not kings – in the development toward higher levels of sustainability.

The paper offers practical implications insofar as it deconstructs three aspects of transparency encroachment that are enacted by companies. Customer awareness, unique experience and customer contribution are all needed to enact transparency encroachment. It is argued that other companies introducing sustainability value propositions to encroach markets should find their own application of these three aspects to create the potential for successful encroachment.

Because of the focus on sustainability aspects of value propositions, this study generates knowledge about the marketing and encroachment of products with a relatively positive impact on society. Adoption of the identified concept of transparency encroachment contributes to sustainable development.

To date, there has been very little marketing research that explores the role of sustainability value propositions in the encroachment of markets. Nonetheless, nowadays customers seem to look beyond their own benefits and are increasingly demanding a new approach that builds upon the sustainability aspects of products. This research adds greater clarity to encroachment through sustainability value propositions.

In the (A) case, Jason Phillips, Chief Financial Officer of a soup manufacturing business, is given the task of maximizing the value of the firm twelve months after the case is set. Although he does not want to break any legal rules, Jason is interested to see whether accounting and real action choices can be used to enhance the company's financial position and increase its perceived value to investors. The case permits him to select from a menu of options, including decisions on product pricing, inventory levels, accounts receivables, leasing or purchasing a new machine and valuation or sale of securities. These choices are fed into an Excel spreadsheet which adjusts financial projections and accounting disclosures accordingly.

In the (B) case, Ben Kerr, Chief Investment Officer at one of Dragon's main competitors, considers the financial statements produced by Dragon to unravel any earnings management behavior and establish a true value for the company. Although the case can be focused on the accounting consequences of real decisions, a richer discussion is obtained when considering the ethical angles of the decision process. In particular, how much “earnings management” should be pursued and what types of behaviors are simply going to be unraveled by investors?

Students will explore: the concepts of “legal” earnings management as compared to true value optimization; whether sophisticated investors misled by such behaviors; and the management of information flows to investors.
