Abstract
Information systems research methods need to contribute to the scholarly requirements of the field of knowledge but also need to develop the potential to contribute to the practical requirements of practitioners′ knowledge. This leads to possible conflicts in choosing research methods. Argues that the changing world of the IS practitioner is reflected in the changing world of the IS researcher and that qualitative approaches to IS research help to bridge the gap between the two domains of knowledge. Illustrates how this gap may be bridged through discussing the ethnographic research method. Concludes by assessing the contributions and limitations of this method to IS research and practice.

Abstract
The roles and functions of a school psychologist are multifaceted. School psychologists are traditionally trained in areas of assessment, intervention, consultation, and program evaluation, though they often participate in prevention and crisis intervention efforts and program evaluation (Harvey & Struzziero, 2008). School psychologists work at district, building, and individual student levels to provide comprehensive and effective services to children and families. Despite a wide range of responsibilities, the school psychologist works in conjunction with other school professionals (e.g., general and special education teachers, speech-language pathologists, audiologists, social workers, principals) and parents to foster individual student success. This chapter presents the general roles and responsibilities of the school psychologist, as well as the school psychologist’s role within an interdisciplinary team when making appropriate educational decisions.

Abstract
Statistical inference (estimation and testing) for the stochastic volatility (SV) model Taylor (1982, 1986) is challenging, especially likelihood-based methods which are difficult to apply due to the presence of latent variables. The existing methods are either computationally costly and/or inefficient. In this paper, we propose computationally simple estimators for the SV model, which are at the same time highly efficient. The proposed class of estimators uses a small number of moment equations derived from an ARMA representation associated with the SV model, along with the possibility of using “winsorization” to improve stability and efficiency. We call these ARMA-SV estimators. Closed-form expressions for ARMA-SV estimators are obtained, and no numerical optimization procedure or choice of initial parameter values is required. The asymptotic distributional theory of the proposed estimators is studied. Due to their computational simplicity, the ARMA-SV estimators allow one to make reliable – even exact – simulation-based inference, through the application of Monte Carlo (MC) test or bootstrap methods. We compare them in a simulation experiment with a wide array of alternative estimation methods, in terms of bias, root mean square error and computation time. In addition to confirming the enormous computational advantage of the proposed estimators, the results show that ARMA-SV estimators match (or exceed) alternative estimators in terms of precision, including the widely used Bayesian estimator. The proposed methods are applied to daily observations on the returns for three major stock prices (Coca-Cola, Walmart, Ford) and the S&P Composite Price Index (2000–2017). The results confirm the presence of stochastic volatility with strong persistence.

Abstract
Purpose
This study explores how a small minority of social entrepreneurs break free from third sector constraints to conceive, create and grow non-profit organisations that generate social value at scale in new and innovative ways.
Design/methodology/approach
Six narrative case histories of innovative social enterprises were developed based on documents and semi-structured interviews with founders and long serving executives. Data were coded “chrono-processually”, which involves locating thoughts, events and actions in distinct time periods (temporal bracketing) and identifying the processes at work in establishing new social ventures.
Findings
This study presents two core findings. First, the paper demonstrates how successful social entrepreneurs draw on their lived experiences, private and professional, in driving the development and implementation of social innovations, which are realised through application of their capabilities as analysts, strategists and resources mobilisers. These capabilities are bolstered by personal legitimacy and by their abilities as storytellers and rhetoricians. Second, the study unravels the complex processes of social entrepreneurship by revealing how sensemaking, theorising, strategizing and sensegiving underpin the core processes of problem specification, the formulation of theories of change, development of new business models and the implementation of social innovations.
Originality/value
The study demonstrates how social entrepreneurs use sensemaking and sensegiving strategies to understand and address complex social problems, revealing how successful social entrepreneurs devise and disseminate social innovations that substantially add value to society and bring about beneficial social change. A novel process-outcome model of social innovation is presented illustrating the interconnections between entrepreneurial cognition and strategic action.

Abstract
This chapter focuses on practical considerations for organizations when endeavoring to invest in design, specifically how designers and their organizations should view their profession for the benefit of corporate innovation. Given the lack of consensus regarding what strategic design entails, the author interviewed strategic designers from across the United States to solicit their opinions on design thinking, strategic design, and design strategy, the relationship between those concepts, and how those concepts are, could be, and should be reflected in practice.
The overarching purpose of this chapter is to explore the relatively nascent profession of strategic design, from which the author distinguishes design strategy, as well as to provide guidance regarding how design and designers should be viewed and supported by the leadership of their organizations in order to fully empower them to support innovation. In addition, this chapter serves to better define the concepts of design thinking, strategic design, and design strategy. While design as a discipline is broad, for the sake of consistency, the author discusses design in the context of technological development and, in turn, in terms of human-computer interaction.

Abstract
In interviews, Jamie Lee Curtis positions Halloween (2018) as a #MeToo film. As merely self-serving publicity, this reading is far too simplistic. In Halloween (1978) Laurie Strode is victimised; she then assumes the role of quintessential Final Girl as described by Carol J. Clover, providing the template for the entire sub-genre of horror slasher films birthed in its wake. However, in the similarly titled 2018 film, Laurie is no longer a victim. Instead of following the role of the stereotypical Final Girl of slasher films, she falls more in line with one of Yvonne Tasker's Warrior Women.
This chapter investigates Laurie Strode's transformation throughout the Halloween franchise. Once passive and victimised, Laurie has evolved: No longer the Final Girl – or victim – her position and behaviour in this film is much more in line with the neoliberal Warrior Woman of action films. Thus, the film assigns her the role of action heroine as a vehicle for responding to the concerns of the #MeToo era – and in this era, women are no longer victims. Women can and will fight back.
