Exploring observational learning in leadership development for managers

Purpose: Observational learning within the leadership development of managers is under-theorized thus far. The purpose of this paper is to develop a theoretical argument that builds out from a relational leadership perspective to center on processes affecting observational learning. Design/methodology/approach: The contribution is to draw together research to build a holistic model of observational learning. A further contribution is to apply this model to the context of leadership development. Findings: The paper examines processes associated with attention, availability, access, attainability, motivation and social comparison with significant others in particular contexts. The paper takes a temporal perspective to examine the ways that such interaction appears to be most prominent at particular times. Research limitations/implications: The paper concludes by outlining the opportunities for applying this understanding of observational leadership learning within management development arenas and explore future directions for research. Originality/value: Observational learning has been relatively overlooked. Though the authors often "know" that leaders develop through experience, the role of observational learning in this experience is not well understood. This paper is intended to provide a stimulus for exploring this important area in terms of shaping thinking and designs for management development interventions. © Emerald Group Publishing Limited.

Weeds and wildlife: perceptions and practices of weed managers

Negative impacts of invasive plants or weeds on biodiversity have been well established yet their role in providing key habitats and resources for wildlife has been little understood. Weed removal thus has the potential to adversely affect wildlife but whether this is considered during weed management is poorly known. To determine the extent of this knowledge, we examined the perceptions of weed managers regarding wildlife and weed management in Victoria, Australia. We surveyed 81 weed managers of varying levels of experience from different types of organisations, including state and local government, community groups and private companies. We found 90% of managers had observed wildlife-weed interactions and that most (70%) adjusted management programmes to accommodate wildlife. Despite this, few (19%) had adopted the recommended practice of combining gradual weed removal with re-vegetation. While management programmes included monitoring of native vegetation, consideration of wildlife monitoring in weed management was rare. This highlights the need for management to better understand and respond to wildlife-weed relationships. If the improvement of wildlife habitat is included in the objectives of weed programmes, as it should be, then wildlife should also be incorporated in project monitoring. This would lead to a greater understanding of the role weeds and their management have in each situation and, ultimately, more informed decision making. Copyright: © Carlos et al. 2014.

Corporate social responsibility disclosures and earnings quality: Are they a reflection of managers’ opportunistic behavior?

Purpose – This paper aims to explore the relationship between corporate social responsibility (CSR) disclosures and earnings quality proxied by earnings accruals. Specifically, we examine whether CSR disclosures are context-specific, that is, whether companies dominated by powerful stakeholders are obliged to behave in a responsible manner to constrain earnings management, thereby reporting higher-quality earnings to investors. Design/methodology/approach – This paper explores the relationship between CSR disclosures and earnings quality proxied by earnings accruals. Specifically, we examine whether CSR disclosures are context-specific, that is, whether companies dominated by powerful stakeholders are obliged to behave in a responsible manner to constrain earnings management, thereby reporting higher-quality earnings to investors. Findings – Results show that managers in an emerging economy manage earnings when they provide more CSR disclosures. Such earnings management is achieved through income increasing discretionary accruals. Furthermore, companies from export-oriented industries dominated by powerful stakeholders (international buyers) disclosing more CSR activities, provide transparent financial reports through constraining earnings management. Originality/value – The findings of this study are significant for both investors and policymakers. Investors should not take for granted that firms engage in CSR activities, behave ethically and provide transparent financial reports. As we document that firms might manipulate earnings through discretionary accruals and provide less transparent financial reports to shareholders, the credibility of firms’ CSR policies should be assessed with caution. Policies directing at promoting socially responsible practices instead of motivating the desired behaviour, may provide managers with additional incentives to utilise CSR for opportunistic behaviour. Thus, policymakers need to be cautious about this opportunistic behaviour and enhance monitoring to enforce social compliance. Possibly, some guidelines can be introduced to confirm that CSR disclosures are based on actual practice and not just a “green wash” statement to deceive stakeholders.

Community aged care case managers transitioning to consumer directed care: more than procedural change required

Consumer directed care (CDC) is increasing in community aged care. However, limited information is available to successfully transition social workers and other case managers to their new role. This paper reports on a case study of six senior case managers who supervised staff in three Australian community-aged care agencies as they transitioned from agency directed care to consumer directed care. A change management framework was used to analyse the qualitative data collected in 12 semistructured interviews. A key finding is that changes in values, attitudes, and organisational culture are needed before staff can fully implement CDC principles of service user self-determination, empowerment, and choice. Process changes needed to assist staff transition to CDC are: using a change management strategy that maximises certainty; monitoring and responding to feelings of anxiety through ongoing consultations; and providing ongoing education and support in group sessions.

An exploratory study on the factors influencing managers’ use of mobile tablets

Although mobile tablets such as iPads are being used by many managers, there has been a relative dearth of research on the managerial use of the mobile technology. This exploratory study aims toidentify and understand the factors influencing the use of mobile tablets by managers. Semi-structured interviews were conducted with a panel of seven managers who had incorporated mobile tablets into their work routine. The study has found that the mobile tablet is a suitable device for managerial tasks due to these nine main factors: non-routineness, collaborative nature, time-critical, informationcentric, mobility, user friendliness of the interface, reliability, connectivity, and autonomy. Thisexploratory study fills in the research gap and provides a basis to help managers establish a business case for or against mobile tablets adoption.

Political connections, founder-managers, and their impact on tunneling in China’s listed firms

We investigate the impact of manager political connection and founder status on tunneling in China's listed firms from 2004 to 2010. By classifying the political connections into three dimensions with two categories of controlling ownerships, we find that overall manager political connection is negatively related to tunneling in private firms but positively related to tunneling in SOEs. The CPC/CPPCC-type connection is likely to protect firms from tunneling, while the official-type connection facilitates tunneling from firms. The impact of these two types of political connection on tunneling is stronger at the central level than the local level. A chairman's political connection has significantly greater influence on tunneling than a CEO's connection. We also find that firms with founder-managers have a stronger resistance to tunneling than those with non-founder-managers, which is still observed in firms with politically connected founder-managers. Our results show that the incentives of various managers towards tunneling depend on their motivation for establishing relevant political connections.

Enhancing predictive accuracy of cardiac autonomic neuropathy using blood biochemistry features and iterative multitier ensembles

Blood biochemistry attributes form an important class of tests, routinely collected several times per year for many patients with diabetes. The objective of this study is to investigate the role of blood biochemistry for improving the predictive accuracy of the diagnosis of cardiac autonomic neuropathy (CAN) progression. Blood biochemistry contributes to CAN, and so it is a causative factor that can provide additional power for the diagnosis of CAN especially in the absence of a complete set of Ewing tests. We introduce automated iterative multitier ensembles (AIME) and investigate their performance in comparison to base classifiers and standard ensemble classifiers for blood biochemistry attributes. AIME incorporate diverse ensembles into several tiers simultaneously and combine them into one automatically generated integrated system so that one ensemble acts as an integral part of another ensemble. We carried out extensive experimental analysis using large datasets from the diabetes screening research initiative (DiScRi) project. The results of our experiments show that several blood biochemistry attributes can be used to supplement the Ewing battery for the detection of CAN in situations where one or more of the Ewing tests cannot be completed because of the individual difficulties faced by each patient in performing the tests. The results show that AIME provide higher accuracy as a multitier CAN classification paradigm. The best predictive accuracy of 99.57% has been obtained by the AIME combining decorate on top tier with bagging on middle tier based on random forest. Practitioners can use these findings to increase the accuracy of CAN diagnosis.

Analyzing systolic-diastolic interval interaction characteristics in diabetic cardiac autonomic neuropathy progression

Cardiac autonomic neuropathy (CAN), one of the major complications in diabetes, if detected at the subclinical stage allows for effective treatment and avoiding further complication including cardiovascular pathology. Surface ECG (Electrocardiogram)-based diagnosis of CAN is useful to overcome the limitation of existing cardiovascular autonomic reflex tests traditionally used for CAN identification in clinical settings. The aim of this paper is to analyze the changes in the mechanical function of the ventricles in terms of systolic-diastolic interval interaction (SDI) from a surface ECG to assess the severity of CAN progression [no CAN, early CAN (ECAN) or subclinical CAN, and definite CAN (DCAN) or clinical CAN]. ECG signals recorded in supine resting condition from 72 diabetic subjects without CAN (CAN-) and 70 diabetic subjects with CAN were analyzed in this paper. The severity of CAN was determined by Ewing's Cardiovascular autonomic reflex tests. Fifty-five subjects of the CAN group had ECAN and 15 subjects had DCAN. In this paper, we propose an improved version of the SDI parameter (i.e., TQ/RR interval ratio) measured from the electrical diastolic interval (i.e., TQ interval) and the heart rate interval (i.e., RR interval). The performance of the proposed SDI measure was compared with the performance of the existing SDI measure (i.e., QT/TQ interval ratio). The proposed SDI parameter showed significant differences among three groups (no CAN, ECAN, and DCAN). In addition, the proposed SDI parameter was found to be more sensitive in detecting CAN progression than other ECG interval-based features traditionally used for CAN diagnosis. The modified SDI parameter might be used as an alternative measure for the Ewing autonomic reflex tests to identify CAN progression for those subjects who are unable to perform the traditional tests. These findings could also complement the echocardiographic findings of the left ventricular diastolic dysfunction by providing additional information about alteration in systolic and diastolic intervals in heart failure.
