Effects of control on the performance of information systems projects: The moderating role of complexity risk

Control of projects is a core issue for organizations. Successful projects, such as information systems projects, enable organizations to develop a superior supply network and enhance the capability of operations management. A few studies have investigated the effects of control on project performance; however, complexity risk has not been integrated into the relationship between control and performance. Limited evidence has been provided concerning whether modes of control differ in their effectiveness in the presence of a single risk factor. Based on quantitative data obtained from 128 information systems projects, behavior, outcome, clan, and self-control are empirically determined to be positively associated with the system performance of projects. However, complexity risk generates a mixed moderating effect on the relationship between control and performance. In the presence of a high complexity risk, the effects of behavior and self-control on performance are low, whereas the effectiveness of outcome and clan control increases. This finding implies that complexity risk is a double-edged sword with regard to control. Each control mode exhibits different characteristics and effectiveness under high complexity risk. Therefore, appropriate control modes should be carefully selected, and highly effective control modes, such as outcome and clan control, should be prioritized in managing complex system projects.

Job satisfaction in aging workforces: an analysis of the USA,Japan and Germany

In light of the dramatically aging workforces in many industrialized countries, age diversity management will become a major challenge in human resource management. To successfully handle an age-diverse workforce, it is crucial to understand how employees of different ages can be motivated. This paper analyzes age's moderating role in the relationship between situational job characteristics and job satisfaction. To control for the potential influence of the cultural and institutional context, we use data from the USA, Japan and Germany. Findings show that older employees' job satisfaction is driven by different factors than younger employees: older employees put more emphasis on good relationships with colleagues, while income, advancement opportunities, job security and having an interesting job are less important. However, these effects are mostly nation-dependent, which underlines the importance of conducting cross-cultural or cross-national aging research.

Supply chain risk analysis: a shipbuilding industry case

A lack of empirical studies on Supply Chain Risk Management (SCRM) is observed, especially in the industries of large projects. Therefore, this paper conducts a risk analysis on the Brazilian Shipbuilding Industry by generating an initial risk profile. A panel was conducted with executives from major shipyards, and the primary risks were identified, assessed, and evaluated. Findings corroborate the academic literature, reinforcing that companies recognise the importance of SCRM, but the concept is incipient and far from being successfully implemented in real life. Despite the fact that the shipyards identified important risks, the focus was on internal factors. Because the industry was exposed to risks from the external environment, no risk mitigation actions existed, resulting in the bankruptcy of many shipbuilders. This research is an initial step toward investigating SCRM techniques, offering academics a novel empirical approach that can serve as a systematic risk management tool for supply chain planning.     

The consequences of managerial indiscretions: Sex,lies, and firm value

Personal managerial indiscretions are separate from a firm's business activities but provide information about the manager's integrity. Consequently, they could affect counterparties’ trust in the firm and the firm's value and operations. We find that companies of accused executives experience significant wealth deterioration, reduced operating margins, and lost business partners. Indiscretions are also associated with an increased probability of unrelated shareholder-initiated lawsuits, Department of Justice and Securities and Exchange Commission investigations, and managed earnings. Further, chief executive officers and boards face labor market consequences, including forced turnover, pay cuts, and lower shareholder votes at re-election. Indiscretions occur more often at poorly governed firms where disciplinary turnover is less likely.     

Stock liquidity and managerial short-termism

We examine whether stock liquidity exacerbates or mitigates managerial short-termism. Utilizing earnings management as a proxy for managerial short-termism, we establish three major findings. First, firms with liquid stocks engage in less accrual-based and real earnings management. Second, the effect of stock liquidity on earnings management is amplified for firms with high levels of managerial pay-for-performance sensitivity. Third, the positive association between the intensity of earnings management and firm cost of capital is evident only for firms with low stock liquidity. Our findings are consistent with the threat of blockholder exit as the main governance channel through which stock liquidity discourages opportunistic earnings management and mitigates managerial short-termism.     

An empirical investigation of water consumption forecasting methods

Many regions on earth face daily limitations in the quantity and quality of the water resources available. As a result, it is necessary to implement reliable methodologies for water consumption forecasting that will enable the better management and planning of water resources. This research analyses, for the first time, a large database containing data from 2 million water meters in 274 unique postal codes, in one of the most densely populated areas of Europe, which faces issues of droughts and overconsumption in the hot summer months. Using the R programming language, we built and tested three alternative forecasting methodologies, employing univariate forecasting techniques including a machine-learning algorithm, with very promising results.
