Accounting change and value creation in public services—Do relational archetypes make a difference in improving public service performance?

Evidence points out that the outcome of accounting change in local governments is not simply a matter of ‘corporate’ resource investments and change management activities to accounting system replacement. This paper examines the link between such corporate-level interventions and the patterns of value creation at street-level. It emphasizes a resource- and capability-driven approach to explore processes and consequences of an ‘embedded agency’-effect assigned to the street-level rationale of public service improvement. Considering a logic chain of cause-and-effect sequences, the data analysis provides evidence that corporate and street-level interventions are unique dimensions to signify the multiple patterns of accounting change in local governments. The supplementary effect of cross-functional relationships is also distinguished, considering the relational archetype as a mechanism to explain the emerging outcome state. Recognizing the distinction and the sequential effects of relational archetypes induces a refined typology of accounting change according to its processes and outcomes in local governments. The analysis is based on a comparative case study design to explore accrual accounting introduction in six German municipalities.     

Indian textile suppliers' sustainability evaluation using the grey approach

Textile supply chains consist of multinational garment retailers (customers), garment manufacturers (suppliers), and ancillary suppliers (suppliers to manufacturers). This paper evaluates suppliers' within the Indian textile and clothing industry (both garment manufacturers and ancillary suppliers) using sustainability criteria. Examining a sample of sixty-three suppliers and six sustainability criteria (i.e. discrimination, abuse of human right, child labor, long working hours, unfair competition, and pollution), we categorize suppliers into the three categories of ‘good performer’, moderate performer’, and ‘performance not up to expectation’. Since all the criteria are potentially subjective, we have employed the grey approach for analysis. The results indicate that the criterion of long working hours is a critical one for both categories of suppliers; in the case of garment manufacturers, we found that pollution and unfair competition were the most important criteria. In addition, employing child labor was found to be a critical criterion in the case of ancillary suppliers.

Is digital technology the magic bullet for performing work at home? Lessons learned for post COVID-19 recovery in hospitality management

PurposeThe COVID-19 pandemic has suddenly brought about a number of disruptions to when and where work is undertaken for hospitality employees. The rapid spread of COVID-19 forced many hospitality managers to use digital technologies to perform work from home, termed digital work connectivity. Yet little is known about how hospitality employees cope with it. The purpose of this study is to investigate an important yet underspecified issue as to how digital work connectivity can be detrimental for employees’ work behavior.Design/methodology/approachWe test our hypotheses using multi-wave and multi-source data collected from 467 middle managerial-level hospitality employees in China.FindingsThe findings show that digital work connectivity can lead to self-control depletion, which in turn is associated with disengagement from work. Further, the findings show that relational energy is an important resource that can buffer the detrimental effects of digital work connectivity on hospitality employees.Practical implicationsThe association of digital work connectivity with employee withdrawal behavior highlights the urgent need for hospitality enterprises to have clear guidelines that regulate technology use at home for work purposes.Social implicationsOur research shows that the absence of clear guidelines in relation to the use of digital technology for work at home risks producing unintended consequences for both hospitality employees and their enterprises.Originality/valueOur research draws from recent advances in resource allocation theories of self-control and adopts a more nuanced approach to uncover a counterintuitive reality that while people use digital technology to remain connected with work, doing so can actually contribute to their withdrawal behavior.
