In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and provides guidance for future mission design, research activities, and sustainable operational radar altimetry data exploitation. Recommendations provided are fundamental for optimizing further scientific and operational advances of oceanographic observations by altimetry, including requirements for spatial and temporal resolution of altimetric measurements, their accuracy and continuity. There are also new challenges and new openings mentioned in the paper that are particularly crucial for observations at higher latitudes, for coastal oceanography, for cryospheric studies and for hydrology. The paper starts with a general introduction followed by a section on Earth System Science including Ocean Dynamics, Sea Level, the Coastal Ocean, Hydrology, the Cryosphere and Polar Oceans and the “Green” Ocean, extending the frontier from biogeochemistry to marine ecology. Applications are described in a subsequent section, which covers Operational Oceanography, Weather, Hurricane Wave and Wind Forecasting, Climate projection. Instruments’ development and satellite missions’ evolutions are described in a fourth section. A fifth section covers the key observations that altimeters provide and their potential complements, from other Earth observation measurements to in situ data. Section 6 identifies the data and methods and provides some accuracy and resolution requirements for the wet tropospheric correction, the orbit and other geodetic requirements, the Mean Sea Surface, Geoid and Mean Dynamic Topography, Calibration and Validation, data accuracy, data access and handling (including the DUACS system). Section 7 brings a transversal view on scales, integration, artificial intelligence, and capacity building (education and training). Section 8 reviews the programmatic issues followed by a conclusion.

Environmental sustainability constitutes an important part of the political and educational context in China as it strives to move toward an ecological civilization. However, there is limited literature documenting the ways in which sustainability is embedded in higher education (HE) teaching. This qualitative research involves interviews and focus groups with 30 faculty in Business and Economics disciplines at three high-ranked Chinese Universities and offers an original exploration of how they include environmental sustainability in their teaching, and the opportunities and challenges they encounter. The findings are significant in suggesting that a broad range of sustainability concepts and aligned pedagogies are incorporated but that political and institutional culture, limitations on obtaining research data, constraints on curriculum design, and individual beliefs are significant barriers to implementation. Strategies employed by faculty to embed sustainability are investigated and reviewed in the context of the 'theory of the second best', previously used in UK research.

The second year of university is little-researched, despite being a focal point for declining performance, persistence, and satisfaction. It is important to establish appropriate methods for studying this 'sophomore slump' and to pinpoint specific antecedents from broad domains noted in literature (e.g. students' social integration, perceptions of the curriculum). Using a novel methodology, 166 undergraduates were surveyed in successive years of study to derive a gold standard 'within-subjects' data sample. Under a replicated design, a 'between-subjects' sample of over 1000 students completed the same e-survey just once, in year one, two, or three. Quantitative comparison of the responses across years showed over 85% agreement between samples. This endorses between-subject approaches (i.e. simultaneously surveying students from different years) to facilitate rapid interventions that benefit students before they graduate. In terms of detailed findings, year two saw positive trends in students' academic engagement (e.g. self-reported independent study time), social integration (e.g. feeling accepted, involvement in extra-curricular activities), and views on teaching staff (e.g. approachability). Although appraisals remained broadly favourable, there was, in contrast, significant deterioration in global perceptions of the learning atmosphere (e.g. course enjoyment), as well as specific elements of the teaching provision (e.g. contact hours, feedback). Notably, there appeared to be little progression in students' academic self-perceptions (e.g. confidence to make presentations, enter class debates). Year two also saw increased thoughts of drop-out. These results highlight the unique character of the second year at university and indicate potential target areas for enhancing this phase of the undergraduate journey.

Early withdrawal from higher education (HE) programmes can be detrimental for the students and institutions involved. Quantitative research has often concentrated on demographic and social antecedents (e.g. gender, prior education). Other factors may be more open to intervention e.g. students' academic experiences in HE. Using data from an institutional survey (N = 1170), logistic regression tested a range of academic experiences, regarding their relationship to contemplation of withdrawal ('COW': a recognised marker for actual withdrawal). COW was associated with student perceptions of low one-to-one contact with staff; non-traditional delivery methods; low peer-interaction; and high assessment load. Interestingly, COW was not associated with overall contact hours, large classes, or personal tutoring. The contributing factors explained 5.1%-8.6% of variance in COW, suggesting they may be meaningful levers for optimising retention. The paper discusses links to existing literature, future research directions, and applied implications for institutions.

Academic research is increasingly driven by research assessment exercises (in the UK, by the Research Excellence Framework, REF). These aim to compare outputs of researchers in each university with those elsewhere, but evaluation efforts have suffered from widespread criticism. The status of pedagogic research in higher education (HE)--once described as the 'Cinderella' of academia, but now an increasing part of university research activity--has also prompted some controversy. Both policy-makers and academics have raised questions about whether such research is appropriate for submission, and confusion exists over the distinction between pedagogic research and 'scholarship of teaching and learning'. This project, funded by the UK Higher Education Academy, explored the experiences of HE pedagogic researchers in REF2014, and found evidence of barriers to participation. These included concerns about quality, expertise of reviewers, and local and intra-institutional politics, all of which may have limited the inclusion of HE pedagogic research.

University rankings are increasingly important internationally, and in the UK include a sustainability 'Green League'. However, there is little evidence about experiences of studying in 'sustainable universities'. We report an empirical study at five universities in varied positions in the Green League, exploring students' energy literacy, environmental attitudes and perceptions of their institution's energy-saving efforts. Although the link to energy literacy is not clear, findings suggest that there are significant differences between students' environmental attitudes at universities placed at different points in the league. In addition, students at higher ranked universities are more positive about their university's energy-saving efforts, suggesting that these institutions may exhibit more overt manifestations of sustainability. This is important since students report being more likely to choose energy-conservation behaviours if there is visible representation of energy use. The study is the first to attempt a comparison between universities at different positions in a sustainability ranking.

Knowledge exchange (KE) is increasingly important in higher education internationally, yet relatively little attention has been paid to it as a pedagogic opportunity for students. This paper draws on 26 interviews with stakeholders within and outside HE to develop a model of studentled knowledge exchange as a guide for learning through KE. The model includes the following elements: Preconditions, Prior Knowledge, Planning and Place, Pedagogic Context and Product, and offers an analysis of different forms of KE which occur between individuals in a learning triad consisting of student, facilitator and external participant. The research foregrounds a social view of learning where valid knowledge comes from diverse participants in the exchange, including students themselves. Students act as a catalyst for multi-directional KE – a finding which challenges the implied hierarchies evident in much of the literature on this topic. The model is offered as a starting point for developing a pedagogy of KE in higher education. [ABSTRACT FROM AUTHOR]

In recent years, the success rates of different groups of students in higher education have come under considerable scrutiny, with gender and ethnicity identified as key attributes predicting differential achievement of "good degrees". A review of previous studies highlights the need for research which looks beyond "the deficit model" to explain the attainment gap. This research used a mixed-methods approach to explore the academic and social experiences of students, as well as lecturers' views on student achievement, in one UK University. Findings suggest that there are significant differences in motivation and confidence speaking English for different ethnic groups in this study, and a divergence in attendance and study time by gender--both of which may go some way to helping understand the gaps in attainment. In addition, male and BME students tended to overestimate their likelihood of achieving a good degree outcome, compared to other groups.

Purpose: This paper aims to explore the possibilities and problems with engaging in effective communication about sustainability in higher education (SHE) institutions. Design/methodology/approach: Using a case study of a new (post-1992) university in the UK, the research investigated the ways in which sustainability issues were communicated with staff across the institution, and any barriers encountered. Semi-structured interviews and a focus group with selected staff led to the development of four key themes related to different aspects of the communication strategy, and it is these which are explored in this paper. Findings: This research suggests that there are some particular difficulties with regard to communicating messages about sustainability successfully. These relate to the lack of an agreed definition or shared understanding of sustainability, and also to potential individual differences in values and attitudes which may act as a perceptual filter of the message. Research limitations/implications: This is a small-scale project so findings should be treated with caution. However, the lack of previous research in this area gives this interest as an exploratory study. Practical implications: In the context of a large organisation, the research emphasizes the importance of alignment of institutional strategies, in order to provide a coherent view of what the organisation expects from employees. This needs to be supported by staff at the highest level, in order for it to have the maximum impact. Originality/value: This paper is the first to use a model of organisational communication to analyse and evaluate the effectiveness of communication around SHE context.

Education for sustainable development (ESD) is playing an increasing role in the higher education curriculum. However, little previous research exists on lecturers' understanding of and attitudes towards sustainable development. This study used an online questionnaire to investigate lecturers' views of sustainable development and its contribution to the higher education curriculum. The questionnaire asks lecturers from a variety of different disciplines about their views on appropriate pedagogy for ESD, and gives insights into the potential opportunities for and barriers to the incorporation of ESD into higher education. The findings of this survey reveal a wide range of understandings of sustainable development within this institution--and a high level of critical debate about the concept itself. In common with some previous research, there are indications that many lecturers find the language of ESD inaccessible. Despite this, a fairly high level of support for sustainable development is expressed across all discipline areas and a range of suggestions about appropriate pedagogies for ESD are raised. However, the extent to which this enthusiasm can be translated into practical changes to the higher education curriculum remains less certain. (Contains 2 tables and 2 figures.)

This paper reports the findings of a small-scale study that investigated student nurses' use of an online resource in Biology. The think-aloud method was used to explore in detail the ways in which students engaged with this resource and to evaluate the ways and extent to which it might enhance their learning. The students generally expressed positive views about the resource, which they used in a variety of ways to supplement more traditional learning activities. They placed particular emphasis on the benefits of using the resource to reinforce lecture materials and to aid revision for exams. Less frequent, however, were references to deepened understanding of the subject matter, raising questions about the type of learning that students were engaged in. The possibility is discussed that "surface" rather than "deep" learning may be encouraged by this type of resource, and the potential tension is highlighted between the rhetoric of constructivism, which is prevalent in e-learning, and the information transmission model of learning, which is highly influential and often favoured by students. (Contains 2 tables.)

Many observers have commented on disparities between the theoretical understandings of environmental education portrayed in academic literature and the environmental education that takes place in schools. In much of the literature and in curriculum documents there has been an increasing emphasis on promoting positive attitudes towards the environment, and the results of several surveys suggest that many teachers support this aim. This paper explores the beliefs of three geography teachers teaching controversial environmental issues in UK secondary schools. In contrast to the findings of prior studies, the teachers in this study feel strongly that they should try to avoid influencing students' attitudes, or imposing any kind of pro-environmental agenda. There is a substantial divergence between the teachers' beliefs and the espoused aims of much environmental education literature and the geography syllabus they were following. This suggests that, unless curriculum developers take account of teachers' beliefs in designing new curriculum materials, those materials are unlikely to be implemented in their intended format.

A study was conducted to test the hypothesis that vaccination against varicellazoster virus (VZV) would decrease the incidence, severity, or both of herpes zoster and postherpetic neuralgia among older adults. The result showed that the zoster vaccine markedly reduced morbidity from herpes zoster and postherpetic neuralgia among older adults.
