Marine area-based conservation measures including no-take zones (areas with no fishing allowed) are often designed through lengthy processes that aim to optimize for ecological and social objectives. Their (semi) permanence generates high stakes in what seems like a one-shot game. In this paper, we theoretically and empirically explore a model of short-term area-based conservation that prioritizes adaptive co-management: temporary areas closed to fishing, designed by the fishers they affect, approved by the government, and adapted every 5 years. In this model, no-take zones are adapted through learning and trust-building between fishers and government fisheries scientists. We use integrated social-ecological theory and a case study of a network of such fisheries closures (“fishing refugia”) in northwest Mexico to hypothesize a feedback loop between trust, design, and ecological outcomes. We argue that, with temporary and adaptive area-based management, social and ecological outcomes can be mutually reinforcing as long as initial designs are ecologically “good enough” and supported in the social-ecological context. This type of adaptive management also has the potential to adapt to climate change and other social-ecological changes. This feedback loop also predicts the dangerous possibility that low trust among stakeholders may lead to poor design, lack of ecological benefits, eroding confidence in the tool’s capacity, shrinking size, and even lower likelihood of social-ecological benefits. In our case, however, this did not occur, despite poor ecological design of some areas, likely due to buffering by social network effects and alternative benefits. We discuss both the potential and the danger of temporary area-based conservation measures as a learning tool for adaptive co-management and commoning.

Keystone Predators

Predator recovery often leads to ecosystem change that can trigger conflicts with more recently established human activities. In the eastern North Pacific, recovering sea otters are transforming coastal systems by reducing populations of benthic invertebrates and releasing kelp forests from grazing pressure. These changes threaten established shellfish fisheries and modify a variety of other ecosystem services. The diverse social and economic consequences of this trophic cascade are unknown, particularly across large regions. We developed and applied a trophic model to predict these impacts on four ecosystem services. Results suggest that sea otter presence yields 37% more total ecosystem biomass annually, increasing the value of finfish [+9.4 million Canadian dollars (CA$)], carbon sequestration (+2.2 million CA$), and ecotourism (+42.0 million CA$). To the extent that these benefits are realized, they will exceed the annual loss to invertebrate fisheries (−$7.3 million CA$). Recovery of keystone predators thus not only restores ecosystems but can also affect a range of social, economic, and ecological benefits for associated communities.

Natural habitat destruction and fragmentation generate a time-delayed loss of species and associated ecosystem services. As social–ecological systems (SESs) depend on a range of ecosystem services, lagged ecological dynamics may affect their long-term sustainability. Here, we investigate the role of consumption changes for sustainability, under a time-delayed ecological feedback on agricultural production. We use a stylized model that couples the dynamics of biodiversity, technology, human demography and compliance with a social norm prescribing sustainable consumption. Compliance with the sustainable norm reduces both the consumption footprint and the vulnerability of SESs to transient overshoot-and-collapse population crises. We show that the timing and interaction between social, demographic and ecological feedbacks govern the transient and long-term dynamics of the system. A sufficient level of social pressure (e.g. disapproval) applied on the unsustainable consumers leads to the stable coexistence of unsustainable and sustainable or mixed equilibria, where both defectors and conformers coexist. Under bistability conditions, increasing extinction debts reduces the resilience of the system, thus favouring abrupt regime shifts towards unsustainable pathways. Given recent evidence of large extinction debts, such results call for farsightedness and a better understanding of time delays when studying the sustainability of coupled SESs.

English as a foreign language education in East Asia has received repeated criticism for its lack of success in developing sufficient English oral proficiency among its students (Muller at al., 2014). In response to the criticism, the governments of China, Japan and South Korea attempted to include assessment of students’ speaking abilities as part of their high-stakes college entrance exams, hoping for positive washback effects in both primary- and secondary-school English education as well as on shadow education (i.e., non-formal private-sector education). These attempts often failed. In South Korea, a new test called the National English Ability Test (NEAT), which included direct assessment of students’ speaking skill among other skills, was developed in 2012. However, the government's plan to use NEAT to replace the current exam – the Korean College Scholastic Aptitude Test (KCSAT) – was quickly dropped before its implementation. In China, the government has tried to promote more communicative methods of English education through incorporating English speaking test in high-stakes tests such as the Gaokao – college admission tests – in addition to reducing the weight of English in the traditional paper-based exams. However, the policies have received heavy resistance at the regional level and have not been implemented at the national level. In Japan, the government asked universities to accept designated external proficiency tests as part of the Common Test, the existing college entrance exam, in order to make up for the exam's missing speaking component. After a mountain of criticism from test users, implementation of the plan is still pending. In this light, the aim of this paper is to discuss why these policy attempts failed. While these policy attempts occurred in three different contexts, we could see striking underlying commonalities. We argue that these policy attempts were made based on a set of beliefs separate from the reality of the stakeholders (e.g., students, parents and teachers). More specifically, the failures can be largely attributed to the governments’ monolithic view of the English language and their insufficient consideration for equity rather than equality.

Little attention has been paid to the impacts of institutional–human–environment dimen-sions on the outcome of Coronavirus disease 2019 (COVID-19) abatement. Through the diagnosticsocial–ecological system (SES) framework, this review paper aimed to investigate what and howthe multifaceted social, physical, and governance factors affected the success level of seven selectedAsia-Pacific countries (namely, South Korea, Japan, Malaysia, Singapore, Vietnam, Indonesia, andNew Zealand) in combatting COVID-19. Drawing on statistical data from the Our World In Data web-site, we measured the COVID-19 severity or abatement success level of the countries on the basis ofcumulative positive cases, average daily cases, and mortality rates for the period of 1 February 2020to 30 June 2020. A qualitative content analysis using three codes, i.e., present (P), partially present(PP), and absent (A) for each SES attribute, as well as score calculation and rank ordering for govern-ment response effectiveness and the abatement success level across the countries, was undertaken.Not only did the standard coding process ensure data comparability but the data were deemedsubstantially reliable with Cohen’s kappa of 0.76. Among 13 attributes of the SES factors, highfacility adequacy, comprehensive COVID-19 testing policies, strict lockdown measures, imposition ofpenalty, and the high trust level towards the government seemed to be significant in determiningthe COVID-19 severity in a country. The results show that Vietnam (ranked first) and New Zealand(ranked second), with a high presence of attributes/design principles contributing to high-levelgovernment stringency and health and containment indices, successfully controlled the virus, whileIndonesia (ranked seventh) and Japan (ranked sixth), associated with the low presence of designprinciples, were deemed least successful. Two lessons can be drawn: (i) having high number of P forSES attributes does not always mean a panacea for the pandemic; however, it would be detrimentalto a country if it lacked them severely, and (ii) some attributes (mostly from the governance factor)may carry higher weightage towards explaining the success level. This comparative study providingan overview of critical SES attributes in relation to COVID-19 offers novel policy insights, thushelping policymakers devise more strategic, coordinated measures, particularly for effective countrypreparedness and response in addressing the current and the future health crisis.

Abstract Background: This study was part of a 15-week sitting light volleyball (SLVB) intervention programme which examined the effectiveness of the intervention on physical and psychological attributes of adults with physical disabilities (PWPD) in Hong Kong. SLVB was a new sport, combing Paralympic volleyball and light volleyball. Gaining an in-depth understanding of the perceptions and experiences of PWPD in the SLVB intervention is critical to further develop SLVB as a PA intervention and sport. Using a social–ecological model (SEM), (a) the participants’ experiences regarding the intervention were assessed and (b) the suitability and feasibility of the SLVB intervention to PWPD were qualitatively examined. Methods: Twenty participants (mean age = 53.52 years standard deviation (SD = 9.02), 60% female participants; 25% had at least a college degree) attended our semi-structured interviews. Results: Using content analysis, their experiences at the individual or intrapersonal level (physical and psychological health, enjoyment, novelty, competence autonomy); interpersonal levels (socialization, teamwork, social support); organizational and community levels (perceived sport venue environment, venue accessibility, safety, dissemination of information, and community facilities); and policy level (resources allocation by the government) were obtained. The participants also commented on the suitability and feasibility of the SLVB intervention for PWPD, contents and coaching, modified rules, duration of session and scheduling, and number of participants and coaches. Conclusion: This qualitative study identified several themes for engaging PWPD in SLVB, and demonstrated that adopting a multilevel approach to intervention in SLVB has positive outcomes to participants. In general, SLVB is suitable and feasible to PWPD. The study contributes to an in-depth understanding of the experiences among PWPD in the SLVB intervention, which is very critical to the further development of SLVB in terms of a PA intervention and sport.

PurposeThe purpose of this research is to gain a better understanding of how a crowd-shipping platform can achieve a critical mass of senders and carrier crowd members to yield network effects that are necessary for the platform to grow and thrive. Specifically, this research studies the participation decisions of both senders and carriers over time and the impacts of the resulting feedback loop on platform growth and performance.Design/methodology/approachAn agent-based model is developed and used to study dynamic behavior and network effects within a simulated crowd-shipping platform. The model allows both carriers and senders to be represented as autonomous, heterogeneous and adaptive agents, whose decisions to participate in the platform impact the participation of other agents over time. Survey data inform the logic governing agent decisions and behaviors.FindingsThe feedback loop created by individual sender and carrier agents' participation decisions generates complex and dynamic network effects that are observable at the platform level. Experimental results demonstrate the importance of having sufficient crowd carriers available when the platform is initially launched, as well as ensuring that sender and carrier participation remains balanced as the platform grows over time.Research limitations/implicationsThe model successfully demonstrates the power of agent-based modeling (ABM) in analyzing network effects in crowd-shipping systems. However, the model has not yet been fully validated with data from a real-world crowd-shipping platform. Furthermore, the model's geographic scope is limited to a single census tract. Platform behavior will likely differ across geographic regions, with varying demographics and sender/carrier density.Practical implicationsThe modeling approach can be used to provide the manager of a volunteer-based crowd-shipping program for food rescue with insights on how to achieve a critical mass of participants, with an appropriate balance between the number of restaurant food donation delivery requests and the number of crowd-shippers available and willing to make those deliveries.Social implicationsThis research can help a crowd-shipping platform for urban food rescue to grow and become self-sustainable, thereby serving more food-insecure people.Originality/valueThe model represents both senders and the carrier crowd as autonomous, heterogeneous and adaptive agents, such that network effects resulting from their interactions can emerge and be observed over time. The model was designed to study a volunteer crowd-shipping platform for food rescue, with participant motivations driven by personal values and social factors, rather than monetary incentives.
