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.

Japanese Expatriate Managers in Japanese Subsidiaries in Brazil: Why Not Learning-driven?

It has been said that international assignments are traditionally “demand- driven” (DD) that is a way of expatriation of executives focused on control, solution of problems and transference of tacit knowledge. Besides that, according to the international literature, “adjustment” is the determinant factor for success in overseas assignments and Japan usually sends their own executives to subsidiaries in other developing countries for “DD” purpose. However, according to the initial empirical study and in-depth interviews, it seems that Japanese expatriate managers in Brazil were sent to learn how to adjust the local staff to their philosophy instead of adjust themselves to a new complete scenario. This paper found that “adjustment” would not be fundamental for Japanese expatriate manager’s success in their assignments to Brazil, since they were under a special “learning-driven” type of expatriation process. This paper also highlights the challenges of the Japanese expatriate managers in Brazil and their contribution to the development of local staff under the internationalization process.

Biased managers, organizational design, and incentive provision

We model the tradeoff between the balance and the strength of incentives implicit in the choice between hierarchical and matrix organizational structures. We show that managerial biases determine which structure is optimal: hierarchical forms are preferred when biases are low, while matrix structures are preferred when biases are high.

Middle managers : estratégias para sobrevivência em ambientes corporativo mutantes

Trabalho de dissertação de mestrado que identifica algumas das estratégias de sobrevivência e de manutenção do trabalho utilizadas pela média gerência de três empresas instaladas no Brasil, uma de alta tecnologia de origem norte-americana, outra de telecomunicação de capital luso-espanhol-brasileiro e a última uma empresa nacional com controle familiar. O estudo busca contextualizar a crescente importância da média gerência para as organizações contemporâneas, caracterizar este grupo de trabalhadores intermediários, delinear e diferenciar alguns de seus possíveis papéis e apresentar algumas de suas vulnerabilidades. Em seguida apresenta dez estratégias identificadas resultantes da análise das entrevistas de quinze gerentes destas empresas. Ao comparar os principais conceitos apresentados por diversos autores sobre a média gerência com as estratégias identificadas dos profissionais brasileiros, percebe-se que há padrões em suas respostas às mudanças em seus ambientes profissionais e que estão relacionados às características do negócio, ao grau de estruturação da organização, à posição que ocupam, ao seu tempo de trabalho e em sua rede de relacionamentos dentro e fora da organização.

A pension manager’s view of exchange traded funds from São Paulo to Santiago

This paper examines the current Chilean and Brazilian pension markets, how these pension markets are structured, how they have historically invested their portfolios in ETFs and how they utilize Exchange Traded Funds (ETFs). This investigation will give an overview of the current pension landscape in each country, ETFs and ETF managers in the region, as well as distribution allowances and regulations for ETF providers within the region. Finally it will offer insights throughout that will be useful to those building a business or creating an expansion plan in Brazil or Chile.

Overconfidence and confirmation bias: are future managers vulnerable?

Decision makers often use ‘rules of thumb’, or heuristics, to help them handling decision situations (Kahneman and Tversky, 1979b). Those cognitive shortcuts are taken by the brain to cope with complexity and time limitation of decisions, by reducing the burden of information processing (Hodgkinson et al, 1999; Newell and Simon, 1972). Although crucial for decision-making, heuristics come at the cost of occasionally sending us off course, that is, make us fall into judgment traps (Tversky and Kahneman, 1974). Over fifty years of psychological research has shown that heuristics can lead to systematic errors, or biases, in decision-making. This study focuses on two particularly impactful biases to decision-making – the overconfidence and confirmation biases. A specific group – top management school students and recent graduates - were subject to classic experiments to measure their level of susceptibility to those biases. This population is bound to take decision positions at companies, and eventually make decisions that will impact not only their companies but society at large. The results show that this population is strongly biased by overconfidence, but less so to the confirmation bias. No significant relationship between the level of susceptibility to the overconfidence and to the confirmation bias was found.
