Devolution and the economy : a Scottish perspective
In their interesting and challenging chapter John Adams and Peter Robinson assess the consequences for economic development policy of the devolution measures enacted by the UK Labour government post 1997. Their chapter ranges widely over current UK regional disparities, the link between devolution and economic growth, the balance of responsibilities in policy between Whitehall and the devolved administrations, and finally, they raise questions about the developing "quasi-federal" role of Whitehall in regulating or coordinating the new devolved policy landscape. In response, we propose to focus on four issues that we believe are key to understanding the economic consequences of devolution both at the Scottish and UK levels. First, we argue that the view of Scotland's devolutionary experience in economic policy is partial and so does not fully capture the nature and extent of change post 1999. Secondly, we examine the role of devolution in regional economic performance. There is much in their paper on this topic with which we agree but we contend that there are significant omissions in the analysis, which are important for policy choice. Our third section highlights an area not discussed in depth by Adams and Robinson's paper: the funding of the devolution settlement. Here we consider some of the implications of funding arrangements for economic performance and the options for a new funding settlement. Finally, we deal with the difficult issue of co-ordination between the centre and the devolved regions. We contend that co-ordination is largely conspicuous by its absence. Moreover, where coordination is deployed it reflects an inadequate understanding of the extent to which the economies of the regions and devolved territories of the UK are linked
The demographic challenge facing Scottish higher education institutions : a computable general equilibrium analysis
Higher Education Institutions (HEIs) are generally regarded as important actors in regional economic development. A large literature exists on their demand side impacts as employers and as purchasers of intermediate inputs and, more recently, work has been undertaken to explore their impacts on the supply side, for example, through labour market and knowledge transfer effects. A growing evidence base suggests that HEIs have a positive impact upon the development of their host regions. However the HEI sector faces a challenge that might have significant impact on the fortunes of its host regions and has hitherto received limited attention. The populations of most developed countries are ageing and the age cohort from which university students are traditionally drawn is expected to shrink. This paper uses an HEIs-disaggregated Computable General Equilibrium (CGE) model to simulate the economic impacts of a shrinking student population upon Scotland. In the analysis we use scenarios presented in a recent Universities UK report. This paper is an output of our project entitled The Overall Impact of HEIs on Regional Economies (ESRC, RES-171-25-0032). This project is one of nine that are funded under the joint UK Higher Education Funding Councils and ESRC Initiative on The Impact of HEIs on Regional Economies. (All UK funding councils are involved: Scottish Funding Council, Higher Education Funding Council for England and Wales, and the Department for Employment and Learning Northern Ireland. We also acknowledge supplementary funding from the Centre for Public Policy for Regions (funded by SFC)
The impact of higher education institutions (HEIs) on the Scottish economy : new evidence from an HEI-disaggregated input-output approach
This paper measures the regional demand impacts on output and employment of Scottish Higher Education Institutions (HEIs) based on Input-Output tables for the year 2006. The HEI disaggregated table was developed from existing Input-Output tables using supplementary data from HESA and purchasing data for Scottish universities. We calculate direct, indirect and induced impacts. Most of the existing literature focuses on individual institutions by employing Keynesian Multiplier or Input-Output analysis. This paper adds to the literature by providing the first systematic study of all individual HEIs using a common framework of analysis. The results suggest that HEIs may have substantial regional economic impacts both in terms of output and employment. Furthermore analysis of the HEIs’ income sources suggests they are more export intensive than is commonly acknowledged, which motivates a re-evaluation of the appropriate counterfactual in regional impact studies of HEIs
Cultural transmission, evolution and revolution in vocal displays : insights from bird and whale song
Funding: ECG is funded by a Royal Society University Research Fellowship.Culture, defined as shared behavior or information within a community acquired through some form of social learning from conspecifics, is now suggested to act as a second inheritance system. Cultural processes are important in a wide variety of vertebrate species. Birdsong provides a classic example of cultural processes: cultural transmission, where changes in a shared song are learned from surrounding conspecifics, and cultural evolution, where the patterns of songs change through time. This form of cultural transmission of information has features that are different in speed and form from genetic transmission. More recently, culture, vocal traditions, and an extreme form of song evolution have been documented in cetaceans. Humpback whale song “revolutions,” where the single population-wide shared song type is rapidly replaced by a new, novel song type introduced from a neighboring population, represents an extraordinary example of ocean basin-wide cultural transmission rivaled in its geographic extent only by humans. In this review, we examine the cultural evolutions and revolutions present in some birdsong and whale song, respectively. By taking a comparative approach to these cultural processes, we review the existing evidence to understand the similarities and differences for their patterns of expression and the underlying drivers, including anthropogenic influences, which may shape them. Finally, we encourage future studies to explore the role of innovation vs. production errors in song evolution, the fitness information present in song, and how human-induced changes in population sizes, trajectories, and migratory connections facilitating cultural transmission may be driving song revolutions.Publisher PDFPeer reviewe
The Wide Field Spectrograph (WiFeS)
This paper describes the Wide Field Spectrograph (WiFeS) under construction
at the Research School of Astronomy and Astrophysics (RSAA) of the Australian
National University (ANU) for the ANU 2.3m telescope at the Siding Spring
Observatory. WiFeS is a powerful integral field, double-beam, concentric,
image-slicing spectrograph designed to deliver excellent thoughput, wavelength
stability, spectrophotometric performance and superb image quality along with
wide spectral coverage throughout the 320-950 nm wavelength region. It provides
a 25x38 arcsec. field with 0.5 arcsec. sampling along each of twenty five 38X1
arcsec slitlets. The output format is optimized to match the 4096x4096 pixel
CCD detectors in each of two cameras individually optimized for the blue and
the red ends of the spectrum, respectively. A process of "interleaved
nod-and-shuffle" will be applied to permit quantum noise-limited sky
subtraction. Using VPH gratings, spectral resolutions of 3000 and 7000 are
provided. The full spectral range is covered in a single exposure at R=3000,
and in two exposures in the R=7000 mode. The use of transmissive coated optics,
VPH gratings and optimized mirror coatings ensures a throughput (including
telescope atmosphere and detector) > 30% over a wide spectral range. The
concentric image-slicer design ensures an excellent and uniform image quality
across the full field. To maximize scientific return, the whole instrument is
configured for remote observing, pipeline data reduction, and the accumulation
of calibration image libraries.Comment: Accepted for publication in Astrophysics & Space Science, 16 pages,

The role of vocal individuality in conservation
Identifying the individuals within a population can generate information on life history parameters, generate input data for conservation models, and highlight behavioural traits that may affect management decisions and error or bias within census methods. Individual animals can be discriminated by features of their vocalisations. This vocal individuality can be utilised as an alternative marking technique in situations where the marks are difficult to detect or animals are sensitive to disturbance. Vocal individuality can also be used in cases were the capture and handling of an animal is either logistically or ethically problematic. Many studies have suggested that vocal individuality can be used to count and monitor populations over time; however, few have explicitly tested the method in this role. In this review we discuss methods for extracting individuality information from vocalisations and techniques for using this to count and monitor populations over time. We present case studies in birds where vocal individuality has been applied to conservation and we discuss its role in mammals
Male-like mudballing behavior of some female fiddler crabs (Uca tangeri)
At each low tide, male and female Uca tangeri
remove mudballs from inside their burrows and place them
on the surface. Previous studies have shown clear intersexual
differences in mudball arrangements. However, we
noticed that some females placed their mudballs in an arrangement
similar to that of males. In this study, we investigated
several factors that may have been responsible for
this change in female mudballing behavior. We found no
significant effect of the lunar cycle, female size and reproductive
state, or burrow features. We briefly discuss the
avoidance of sexual coercion or parasite modification of
host behavior as possible factors. Our study shows that
intersexual differences in mudballing behavior are more
complex than previously thought
Cyr61/CCN1 signaling is critical for epithelial-mesenchymal transition and stemness and promotes pancreatic carcinogenesis
<p>Abstract</p> <p>Background</p> <p>Despite recent advances in outlining the mechanisms involved in pancreatic carcinogenesis, precise molecular pathways and cellular lineage specification remains incompletely understood.</p> <p>Results</p> <p>We show here that Cyr61/CCN1 play a critical role in pancreatic carcinogenesis through the induction of EMT and stemness. Cyr61 mRNA and protein were detected in the early precursor lesions and their expression intensified with disease progression. Cyr61/CCN1 expression was also detected in different pancreatic cancer cell lines. The aggressive cell lines, in which the expressions of mesenchymal/stem cell molecular markers are predominant; exhibit more Cyr61/CCN1 expression. Cyr61 expression is exorbitantly higher in cancer stem/tumor initiating Panc-1-side-population (SP) cells. Upon Cyr61/CCN1 silencing, the aggressive behaviors are reduced by obliterating interlinking pathobiological events such as reversing the EMT, blocking the expression of stem-cell-like traits and inhibiting migration. In contrast, addition of Cyr61 protein in culture medium augments EMT and stemness features in relatively less aggressive BxPC3 pancreatic cancer cells. Using a xenograft model we demonstrated that cyr61/CCN1 silencing in Panc-1-SP cells reverses the stemness features and tumor initiating potency of these cells. Moreover, our results imply a miRNA-based mechanism for the regulation of aggressive behaviors of pancreatic cancer cells by Cyr61/CCN1.</p> <p>Conclusions</p> <p>In conclusion, the discovery of the involvement of Cyr61/CCN1 in pancreatic carcinogenesis may represent an important marker for PDAC and suggests Cyr61/CCN1 can be a potential cancer therapeutic target.</p
