Abstract
Purpose
The purpose of this study was to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) at different frequencies on working memory (WM) and neuroelectric activity in rats.
Design/methodology/approach
Three rTMS protocols involving different frequencies were applied to rats, and 16-channel local field potentials (LFPs) and spikes were recorded from the prefrontal cortex (PFC) of rats in each group during the WM task. First, the behavior of rats during the T-maze task was analyzed, and then, the firing rate of spikes and the energy of the θ-band and γ-band in LFPs when rats performed the WM tasks were calculated. Finally, the spectral coherence between LFPs and spikes was analyzed by wavelet transform.
Findings
The results showed that rats in the stimulation groups needed fewer days than those in the control group to reach the task correction standard during the WM experiment (p < 0.05). High-frequency rTMS increases the firing rate of spikes and the degree of synchronization of LFPs-spikes in the θ-band and γ-band in the WM process.
Originality/value
This study showed that high-frequency rTMS can improve the spatial learning ability of rats, which might be due to the increased neuronal excitability of the PFC and the enhancement of co-coding between different modes of neural signals. This study is helpful for understanding the neuroregulatory mechanism of rTMS and will provide a reference for the selection of a suitable frequency for TMS treatment.

Abstract
Theoretical basis
It is recommended that students apply the arguments of resource-based theory to analyze the potential strategic partnership that the case focuses on. The resource-based view suggests that strategic partnerships between firms have the potential to create value when resources are pooled together. Scott Crump faces a decision-making situation wherein he analyses the value-creation potential of the original equipment manufacturer partnership with Hewlett-Packard (HP). In addition, contrasting the cultural environments within both organizations would bring in greater complexity and depth to the reflections, analyses and discussions. Often research experts explore these concepts in isolated streams of research. However, in real-world scenarios, these aspects must be integrated for a more comprehensive decision making to take place. It is also recommended for students to analyze how founder characteristics and resources imprint organizations with certain enduring “imprints” that determine strategic outcomes for the firm in unique ways.
Research methodology
For the development of this case, the authors interviewed the top management at Stratasys including Scott Crump, Founder and CEO. The authors also interviewed former and current employees of Stratasys, HP, other experts in the printing industry and existing customers in the 3D printing industry. The company made internal documents available to the authors including financial statements, internal meeting presentations, company forecasts and assessment tools. All interviews were recorded and analyzed to obtain and include multiple perspectives from various stakeholders. The authors also conducted extensive online research on the 3D printing industry and utilized data from news articles, interviews and other relevant press materials.
Case overview/synopsis
Scott Crump, Founder of Stratasys, a company that developed and sold 3D printers, had always envisioned a future when it would be commonplace for a 3D printer to be on the desk of every engineer. HP approached him with a proposal that had the potential to make that dream come true. Crump knew that Stratasys did not need to partner with HP for a financial reason, but he loved the idea of the technology becoming a standard method for creating parts universally. The case highlights a true-life account of a firm’s founder considering an important strategic alliance and analyzing the ramifications of taking on or refusing this partnership.
Complexity academic level
This case has applications in strategic management and small business management courses at both undergraduate and graduate levels. It also contains critical areas of decision making relevant to an advanced strategic management course that focuses on manufacturing strategy or strategic alliance decision making. This case would be relevant to MBA, Executive MBA or Masters of Science in Accountancy level students as well. Specifically, it is intended for use in courses involving topics such as mergers and strategic partnerships, negotiation and leadership, risk analysis, financial statement analysis, financial modeling and market analysis.

Abstract
Purpose
While privatisation in education is expanding, the number of children transferring from public to private schools seeking high-quality education has increased. This study examined equality of educational opportunity, focussing on the attributes of individual children and their familial backgrounds. The target country is Nepal, which has been facing an educational disparity problem between public and private schools.
Design/methodology/approach
This study performed a logistic regression analysis with the objective variable as the binary capability to attend a private school and analysed the differences between children who attended public versus private schools. Semi-structured interviews with subjects and teachers and home-visit surveys were conducted to collect and confirm data.
Findings
This study revealed that particular children were excluded from seeking high-quality education in form of attending private schools. These children's characteristics correspond to lower economic status, illiterate mothers, being only children and female. Moreover, the study observed changes in awareness due to the modernisation and globalisation of Nepali society and growing enthusiasm for education, amongst others.
Originality/value
Research on privatisation and access to quality education, which has attracted scholarly attention in recent years, requires a broader scope regarding target countries and more in-depth analyses. This study focussed on Nepal since, in the country, the phenomenon of children leaving public for private schools is prominent and little research has been conducted on this context. Additionally, since the study gathered extensive data on individual children and did not rely on secondary data, it was possible to perform an in-depth analysis and accurately portray the real situation faced by Nepali children.

Abstract
Purpose
Often linked to the New Public Management (NPM) doctrines, agencification has been on the priority list of policy makers for over two decades. This article proposes an analysis of the role of agencies in the French health system and the impact of government agency reform on physicians and the public.
Design/methodology/approach
The research analyzes the perceived implementation of a re-concentration of decision-making powers within public agencies as the declared goal of agencification at the French health care system, specifically primary care providers and hospitals. The assessment relies on secondary sources from ministerial bodies such as the Ministry of Health and Social Affairs, the Ministry of Labor, the Social Security and the General Accounting Office, and specialized French technical agencies.
Findings
Decentralization in France and the subsequent rise of public health care agencies had outcomes below expectations. Hence, a re-concentration of decision-making powers within the larger Regional Health Agencies; a streamlining of the public administration; and a re-appropriation of decision-making powers by the Ministry of Health are needed. The monitoring of health providers allows central health authorities to govern at a distance.
Originality/value
The analysis of health care agencies in France and of their use of efficiency-enhancing techniques may trigger a change of values within the medical profession.
