Recently, the showroom model has developed fast for allowing consumers to evaluate a product offline and then buy it online. This paper aims at exploring the optimal information acquisition strategy and its incentive contracts in an e-commerce supply chain with two competing e-tailers and an offline showroom. Based on signaling game theory, we build a mathematical model by considering the impact of experience service and competition intensity on consumers’ demand. We find that, on the one hand, information acquisition promotes supply chain members to obtain demand information directly or indirectly, which leads to forecast revenue. On the other hand, information acquisition promotes supply chain members to distort optimal decisions, which results in signal cost. The optimal information acquisition strategy depends on the joint impact of forecast revenue, signal cost and demand forecast cost. Notably, in some conditions, the offline showroom will not acquire demand information even when its cost is equal to zero. We also design two different information acquisition incentive contracts to obtain Pareto improvement for all supply chain members.

Travel demand forecast plays an important role in transportation planning. Classic models often predict people’s travel behavior based on the physical built environment in a linear fashion. Many scholars have tried to understand built environments’ predictive power on people’s travel behavior using big-data methods. However, few empirical studies have discussed how the impact might vary across time and space. To fill this research gap, this study used 2019 anonymous smartphone GPS data and built a long short-term memory (LSTM) recurrent neural network (RNN) to predict the daily travel demand to six destinations in Austin, Texas: downtown, the university, the airport, an inner-ring point-of-interest (POI) cluster, a suburban POI cluster, and an urban-fringe POI cluster. By comparing the prediction results, we found that: the model underestimated the traffic surge for the university in the fall semester and overestimated the demand for downtown on non-working days; the prediction accuracy for POI clusters was negatively related to their adjacency to downtown; and different POI clusters had cases of under- or overestimation on different occasions. This study reveals that the impact of destination attributes on people’s travel demand can vary across time and space because of their heterogeneous nature. Future research on travel behavior and built environment modeling should incorporate the temporal inconsistency to achieve better prediction accuracy.

INTRODUCTION:In Europe, the work done by the European Commission and the European Network for Health Technology Assessment (EUnetHTA) has consolidated the role of Health Technology Assessment (HTA), and promises to better harmonize its impact across European Union (EU) countries. However, more work is needed to improve patient involvement in assessing new health technology, and in developing research priorities.METHODS:The European Cancer Patient Coalition (ECPC) developed a model for engagement of patients in HTA based on the experience from: •ECPC's ‘Value of Innovation in Oncology’ White Paper, which includes input from ECPC's membership•ECPC's leading role in the Patient Preferences in Benefit-Risk Assessments during the Drug Life Cycle (PREFER) study, funded by the Innovative Medicines Initiative, to develop guidelines on how patient-preference studies should be performed throughout the development of new medical treatments.RESULTS:The ECPC ‘Value of Innovation in Oncology’ White Paper was launched in 2017. The paper provides ECPC's policy position on key obstacles to equitable access to meaningful innovation. The paper recommends the establishment of an EU-wide HTA body to reduce delays and variations in access and to avoid duplication of effort by individual Member States. The paper also recommends that patients should be formally and routinely included in HTA policy and operations at EU and at national levels. These recommendations were also submitted to the European Commission's public consultation on strengthening EU cooperation on HTA.Through its work in PREFER, ECPC is helping to improve how patient preferences are measured and valued to capture the impact of health technology on patients daily life. Patient preferences are concerned with measuring how patients value components such as treatment end points, route of administration, treatment duration, treatment frequency, frequency of side-effects, price, and quality of life.CONCLUSIONS:Patient organization involvement in HTA is vital. Patient organizations offer unique insights, experiences, identify unmet needs, and can help to produce practical recommendations

The impact of inaccurate demand beliefs on dynamics of a Triopoly game is studied. We suppose that all the players make their own estimations on possible demand with errors. A dynamic Triopoly game with such demand belief is set up. Based on this model, existence and local stable region of the equilibriums are investigated by 3D stable regions of Nash equilibrium point. The complex dynamics, such as bifurcation scenarios and route to chaos, are displayed in 2D bifurcation diagrams, in which e1 and α are negatively related to each other. Basins of attraction are investigated and we found that the attraction domain becomes smaller with the increase in price modification speed, which indicates that all the players’ output must be kept within a certain range so as to keep the system stable. Feedback control method is used to keep the system at an equilibrium state.

Open access book publishing is gaining momentum, with more than 10,000 titles published worldwide. But compared to the overall number of academic books that are produced, this is still a small percentage. With much research on the benefits to society from open access publication, what can we do to encourage more book authors to choose open access?Springer Nature is a leading academic book publisher – to date, we have published more than 550 open access books since launching OA book options in 2012. Feedback from our OA book authors has shown that metrics are important to them, as the data helps demonstrate the impact of their research to funders, and also supports conversations with their institutions for career progression. However, as highlighted in our white paper ‘The OA effect: How does open access affect the usage of scholarly books?’, some authors feel that there is a lack of information around metrics and book performance. This information may be critically important in helping authors consider the benefits of choosing to publish their book open access.Authors also state that one of the main obstacles to publishing more OA books through the gold route is funding; access to which varies globally and by discipline – a central theme that emerged at our researcher event during Academic Book Week 2018.Meanwhile, funders interviewed for ‘The OA Effect’ told us that they were keen to understand the impact of the OA books they had supported, but few had actually done so; many commented on the difficulties of measuring the impact of research.  In light of these findings, in 2018 we piloted a new “impact report”, based on metrics for an individual funder of OA books. The outcomes of this pilot impact report project will help the scholarly communications community to better understand how publishers can inform funders, authors and their institutions about the impact of their research, and on a wider scale. What are the challenges of sharing the benefits of OA book publishing with researchers across different disciplines, and how can we overcome these challenges?Our poster shows excerpts from the pilot impact report, quotes from authors and funders about research impact, and considers next steps.

This article analyzes the influence that the educational ideas proposed by UNESCO had on the development of the General Education Act (LGE) of 1970. More specifically, it attempts to establish the impact that this international organization had on the origin and development of the LGE during the Franco regime. To do so, the first part of the article studies the beginnings of UNESCO in Spain and how the educational conception that would give rise to one of the most important educational reforms of contemporary Spain was developed. In the second part, we examine the recommendations given by the «International Advisory Committee for the Reform of Education in Spain» regarding the debate generated by the Libro Blanco (White Paper). In the third part of the article we look at the Committe’s direct impact and the way its assessments guided the development of the LGE in its first years. This work aims to demonstrate that the LGE can be better understood as a reform born under the recommendations of UNESCO regarding the educational context originated within the framework of the Cold War and the Modernization Theory.

Socio-economic and vocational needs of communities, governments and individuals change over the years and these discourses served as a compass for restructuring of higher institutions in South Africa from 1994. Before 1994, the claim to legitimacy for government policies in higher education rested on meeting primarily the interests of the white minority. From 1996 onwards, the newly established government considered education a major vehicle of societal transformation. The main objective had been to focus on reducing inequality and fostering internationalisation. Therefore, the rationale for the restructuring of South African universities included a shift from science systems to global science networks. Various challenges are associated with restructuring and include access, diversity, equity and equality. Thus, the restructuring and mergers between former technikons and traditional universities were probably the most difficult to achieve in terms of establishing a common academic platform, as transitional conditions also had to be taken into account and had a twin logic: It was not only the legacy of apartheid that had to be overcome but the incorporation of South Africa into the globalised world was equally important as globalisation transforms the economic, political, social and environmental dimensions of countries and their place in the world. Initially, the post-apartheid higher education transformation started with the founding policy document on higher education, the Report of the National Commission on Higher Education and this report laid the foundation for the 1997 Education White Paper 3 on Higher Education in which a transformed higher education system is described. Restructuring and mergers also had a far-reaching impact, positive and negative, on the various tertiary institutions. This article also reflects on the impact of restructuring and mergers of higher education and reaches the conclusion that higher education faces many more challenges than initially anticipated prior to transformation.
