Studying Your Own Country. Social Scientific Knowledge For Our Times and Places; Presidential Address to the Canadian Political Science Association, St Catharines, May 28, 2014

Political science is both a generalizing and an anchored, nationally defined, discipline. Too often, the first perspective tends to crowd out the latter, because it appears more prestigious, objective, or scientific. Behind the international/national dichotomy, there are indeed rival conceptions of social science, and important ontological, epistemological and methodological assumptions. This article discusses these assumptions and stresses the critical contribution of idiographic, single-outcome studies, the importance of producing relevant, usable knowledge, and the distinctive implications of studying one’s own country, where a scholar is also a citizen, involved in more encompassing national conversations. The aim is not to reject the generalizing, international perspective, or even the comparative approach, but rather to reaffirm the importance of maintaining as well, and in fact celebrating, the production of social scientific knowledge directly relevant for our own times and places.La science politique est une discipline qui aspire à la fois à la généralisation et à la production de connaissances ancrées localement, sur le plan national. Trop souvent, la première perspective domine la seconde, parce qu’elle apparait plus prestigieuse, objective ou scientifique. La dichotomie international/national recouvre en effet des postulats fort différents en ce qui concerne les fondements ontologiques, épistémologiques et méthodologiques de la discipline. Cet article discute ces postulats et souligne la contribution déterminante des études idiographiques, centrées sur des évènements uniques, l’importance de produire des connaissances pertinentes et utilisables, et le caractère distinctif de l’étude de son propre pays, qui fait aussi du chercheur un citoyen impliqué dans de plus larges conversations. Le but n’est pas de rejeter la généralisation ou même l’approche comparative, mais plutôt de réaffirmer l’importance de maintenir également, et même de célébrer, la production de connaissances directement pertinentes pour nos propres temps et milieux de vie

Larval dispersal in a changing ocean with an emphasis on upwelling regions

Dispersal of benthic species in the sea is mediated primarily through small, vulnerable larvae that must survive minutes to months as members of the plankton community while being transported by strong, dynamic currents. As climate change alters ocean conditions, the dispersal of these larvae will be affected, with pervasive ecological and evolutionary consequences. We review the impacts of oceanic changes on larval transport, physiology, and behavior. We then discuss the implications for population connectivity and recruitment and evaluate life history strategies that will affect susceptibility to the effects of climate change on their dispersal patterns, with implications for understanding selective regimes in a future ocean. We find that physical oceanographic changes will impact dispersal by transporting larvae in different directions or inhibiting their movements while changing environmental factors, such as temperature, pH, salinity, oxygen, ultraviolet radiation, and turbidity, will affect the survival of larvae and alter their behavior. Reduced dispersal distance may make local adaptation more likely in well-connected populations with high genetic variation while reduced dispersal success will lower recruitment with implications for fishery stocks. Increased dispersal may spur adaptation by increasing genetic diversity among previously disconnected populations as well as increasing the likelihood of range expansions. We hypothesize that species with planktotrophic (feeding), calcifying, or weakly swimming larvae with specialized adult habitats will be most affected by climate change. We also propose that the adaptive value of retentive larval behaviors may decrease where transport trajectories follow changing climate envelopes and increase where transport trajectories drive larvae toward increasingly unsuitable conditions. Our holistic framework, combined with knowledge of regional ocean conditions and larval traits, can be used to produce powerful predictions of expected impacts on larval dispersal as well as the consequences for connectivity, range expansion, or recruitment. Based on our findings, we recommend that future studies take a holistic view of dispersal incorporating biological and oceanographic impacts of climate change rather than solely focusing on oceanography or physiology. Genetic and paleontological techniques can be used to examine evolutionary impacts of altered dispersal in a future ocean, while museum collections and expedition records can inform modern-day range shifts

Increased Use of Timber in New Buildings in Oslo and Akershus: Potentials and GHG Emission Effects

The choice of materials may play an important role in achieving the common European aims of near zero energy demand and greenhouse gas (GHG) emissions in the lifecycle of buildings. The production of timber materials demands lower emissions than concrete and steel. To guide political and industrial priorities, it is vital to estimate the emission effects of increased use of timber. The article reports on a broad study that had the following aims: 1. To forecast the number, types, floor area, and location of new buildings that will be built in Oslo and Akershus counties between 2015 and 2030. 2. To estimate how many of these new buildings (a) will be and (b) could be built with timber as the main construction material. 3. To compare these timber potentials to the present and future availability of nationally and sustainably sourced and manufactured timber. 4. To estimate the effect on GHG emissions when substituting concrete and steel with timber in the production of new buildings in Oslo and Akershus counties between 2015 and 2030. The research is based on official prognoses for population growth. They are combined with building predictions derived from municipal statistics and plans. A GHG reduction factor is extracted from existing studies of the effects of conversion to timber. This factor is used to estimate the GHG saving potentials of different scenarios for timber use. Main results: • The forecast of building numbers, categories, sizes and location is a useful tool when discussing environmental, urban, industrial and architectural strategies. • Housing in 2–8 stories, not high-rise buildings, represents the biggest potential for increased use of timber in Norway. • Scientific consensus is not established regarding timber buildings and emissions. Especially the effects of carbon storage in long-lived products and use of residues for biofuel substitutes fossil fuel are still debated. To convey an order of magnitude, the different emission-saving effects are separated. • The estimates of GHG mitigation indicate that conversion to use of timber may have significant effects, but measures in the transport sector are more important for reaching the ambitious emission targets in Oslo and Akershus counties. • To be robust, the argument for timber buildings must include the perspective of a green industrial shift based on renewable resources and innovative technology, design and architecture. • The vicinity of Norway’s biggest and most rapidly growing market for timber buildings and the country’s largest forests and timber-based industries represents a unique opportunity for sustainable urban and regional development. Keywords: urban timber buildings, timber building emissions, timber potential, sustainable timber buildings, timber architecture.publishedVersio

Heroic music stimulates empowering thoughts during mind-wandering

It is generally well-known, and scientifically well established, that music affects emotions and moods. However, only little is known about the influence of music on thoughts. This scarcity is particularly surprising given the importance of the valence of thoughts for psychological health and well-being. We presented excerpts of heroic- and sad-sounding music to n = 62 individuals, and collected thought probes after each excerpt, assessing the valence and the nature of thoughts stimulated by the music. Our results show that mind-wandering emerged during listening to either type of music (heroic, sad), and that the type of music strongly influenced the thought contents during mind-wandering. Heroic-sounding music evoked more positive, exciting, constructive, and motivating thoughts, while sad-sounding music evoked more calm or demotivating thoughts. The results thus indicate that music has a strong effect on the valence of thought contents during mind-wandering, with heroic music evoking more empowering and motivating thoughts, and sad music more relaxing or depressive thoughts. These findings have important implications for the use of music in everyday life to promote health and well-being in both clinical populations and healthy individuals.publishedVersio

The effects of musicality on brain network topology in the context of Alzheimer’s disease and memory decline

Music’s role in modulating brain structure, particularly in neurodegenerative contexts such as Alzheimer’s Disease (AD), has been increasingly recognized. While previous studies have hinted at the potential neuroplastic benefits of musical engagement and training, the mechanisms through which music impacts structural connectivity in neurodegenerative pathways remain underexplored. We aimed to examine the impact of music perception skills, active musical engagement, and musical training on structural connectivity in areas relating to memory, emotion, and learning in individuals with worsening memory impairment, investigating the potential neuroplastic effects of music. Employing diffusion tensor imaging (DTI) based structural connectivity and graph theoretical analysis, we investigated brain topological features in 78 participants aged 42 to 85 with a range of memory impairments. Participants were assessed for musical training, engagement, and perception skills. The study analyzed regional and local network topological metrics to examine the influence of musical activities on graph metrics, while controlling for stages of objective memory impairment (SOMI) and diagnosis, separately. This study aimed to elucidate the effects of musical perception skills, active musical engagement, and musical training on structural connectivity within memory, emotion, and learning-related brain areas in individuals with varying degrees of memory impairment. We found enhanced structural connectivity of the right hippocampus and the right posterior cingulate cortex was associated with stronger local network metrics, such as clustering coefficient and betweenness centrality, with increased music perception skills like melody and beat perception. Musical training specifically impacted the clustering coefficient of the right hippocampus and the node degree of the right mid cingulate gyrus. Active musical engagement influenced the eigenvector centrality of the right hippocampus. Furthermore, musical training was associated with enhanced global metrics, such as global efficiency and characteristic path length. Our study integrates diffusion magnetic resonance imaging (MRI) and graph theoretical analysis to reveal significant effects of musical activities on structural connectivity in key brain regions. The results highlight the potential of musical activities to serve as a non-invasive modulatory tool for cognitive resilience, especially in memory impairment and neurodegeneration contexts. These insights contribute to the understanding of delaying AD onset and aiding early-stage patients through music-based interventions, emphasizing the importance of musical engagement in maintaining cognitive and brain health.publishedVersio

Heatwaves and Rising Temperatures in the Upper San Francisco Estuary: Trends and Effects on Ecosystems and Humans

Rising temperature is one direct consequence of climate change, and temperature is a key controlling variable on biological processes from molecular to ecosystem scales. While rising average temperature is one of the most discussed aspects of climate change, extreme events such as heatwaves are also expected to increase in duration, intensity, and frequency. These changes will bring about effects that threaten the integrity of the upper San Francisco Estuary (estuary) ecosystem, the services they provide to humans, and the health of humans that reside in the region. In the estuary, warmer temperatures are expected to result in seasonal shifts to life-cycle timing, and to favor smaller-bodied individuals across most non-human taxa. Several native fish species will likely decline, while a considerable number of non-native and cosmopolitan species tolerant of high temperatures are predicted to be relatively unaffected by or even benefit from a warmer climate. For humans, high temperatures and heatwaves are associated with wide-ranging health effects, from direct effects such as dehydration and heat exhaustion, to indirect and adverse health outcomes such as lower birth weight, mental health problems, and violence. These health effects will be exacerbated by ecosystem changes, as a longer warm season will increase our exposure to vectors such as mosquitos, as well as to the toxins produced by harmful algal blooms. Climate change is a global issue that cannot be resolved effectively at a regional level; however, some actions can either be taken or further studied to potentially lessen the effects of rising temperatures for the estuary’s ecosystem and residents at a more localized level. Although decreasing global greenhouse gas emissions remains our best option to combat climate change and the resultant temperature increases, successful adaptation to warming and heatwaves will require actions at multiple scales

Does a complex life cycle affect adaptation to environmental change? Genome-informed insights for characterizing selection across complex life cycle

Complex life cycles, in which discrete life stages of the same organism differ in form or function and often occupy different ecological niches, are common in nature. Because stages share the same genome, selective effects on one stage may have cascading consequences through the entire life cycle. Theoretical and empirical studies have not yet generated clear predictions about how life cycle complexity will influence patterns of adaptation in response to rapidly changing environments or tested theoretical predictions for fitness trade-offs (or lack thereof) across life stages. We discuss complex life cycle evolution and outline three hypotheses-ontogenetic decoupling, antagonistic ontogenetic pleiotropy and synergistic ontogenetic pleiotropy-for how selection may operate on organisms with complex life cycles. We suggest a within-generation experimental design that promises significant insight into composite selection across life cycle stages. As part of this design, we conducted simulations to determine the power needed to detect selection across a life cycle using a population genetic framework. This analysis demonstrated that recently published studies reporting within-generation selection were underpowered to detect small allele frequency changes (approx. 0.1). The power analysis indicates challenging but attainable sampling requirements for many systems, though plants and marine invertebrates with high fecundity are excellent systems for exploring how organisms with complex life cycles may adapt to climate change

Governing Ecological Connectivity in Cross-Scale Dependent Systems.

Ecosystem management and governance of cross-scale dependent systems require integrating knowledge about ecological connectivity in its multiple forms and scales. Although scientists, managers, and policymakers are increasingly recognizing the importance of connectivity, governmental organizations may not be currently equipped to manage ecosystems with strong cross-boundary dependencies. Managing the different aspects of connectivity requires building social connectivity to increase the flow of information, as well as the capacity to coordinate planning, funding, and actions among both formal and informal governance bodies. We use estuaries in particular the San Francisco Estuary, in California, in the United States, as examples of cross-scale dependent systems affected by many intertwined aspects of connectivity. We describe the different types of estuarine connectivity observed in both natural and human-affected states and discuss the human dimensions of restoring beneficial physical and ecological processes. Finally, we provide recommendations for policy, practice, and research on how to restore functional connectivity to estuaries

Gender-related violence and young people: an overview of Italian, Irish, Spanish, UK and EU legislation

Do laws regarding violence against or sexual exploitation of young people recognise gendered and other power dynamics? Cross‐national comparison of legal texts can illustrate the benefits of framing issues of violence/gender/youth in certain ways and offer critical reflection on particular legal frameworks or cultural understandings. This policy review is based on an analysis of select laws regarding gender‐related violence (GRV) as relates to young people in Italy, Ireland, Spain and the UK. Here, GRV is defined as sexist, sexualising or norm‐driven bullying, harassment, discrimination or violence whoever is targeted. It therefore includes gender, sexuality and sex‐gender normativities, as well as violence against women and girls. A tension emerges between granting young people agency and recognising the multiple, intersecting power relations that might limit and shape that agency. This article draws out the implications for the UK in particular, highlighting the absence of preventative measures and the need for a broader approach to combat GRV
