description: In free-space Quantum Key Distribution in turbulent conditions, scattering and beam wandering cause intensity fluctuations which increase the detected signal-to-noise ratio. This effect can be mitigated by rejecting received bits when the channel's transmittance is below a threshold. Thus, the overall error rate is reduced and the secure key rate increases despite the deletion of bits. In Decoy State BB84 QKD, several methods to find the ideal threshold have already been proposed. One promising method is the Prefixed-Threshold Real-time Selection (P-RTS) where a cutoff can be chosen prior to data collection and independently of the intensity distribution. In this work we perform finite-size Decoy State BB84 QKD in a laboratory setting where we simulate the atmospheric turbulence using an acousto-optical modulator. We show that P-RTS can yield considerably higher secure key rates, especially at higher losses. In addition, we verify that P-RTS gives a robust cutoff even when the predicted transmittance does not match the actual transmittance.

description: We have combined Halpha and recent high resolution CO(J=1-0) data to consider the quantitative relation between gas mass and star formation rate, or the so-called Schmidt law in nearby spiral galaxies at regions of high molecular density. The relation between gas quantity and star formation rate has not been previously studied for high density regions, but using high resolution CO data obtained at the NMA(Nobeyama Millimeter Array), we have found that the Schmidt law is valid at densities as high as $10^3 \mathrm{M_\odot} \mathrm{pc}^{-2}$ for the sample spiral galaxies, which is an order of magnitude denser than what has been known to be the maximum density at which the empirical law holds for non-starburst galaxies. Furthermore, we obtain a Schmidt law index of $N=1.33\pm0.09$ and roughly constant star formation efficiency over the entire disk, even within the several hundred parsecs of the nucleus. These results imply that the physics of star formation does not change in the central regions of spiral galaxies. Comparisons with starburst galaxies are also given. We find a possible discontinuity in the Schmidt law between normal and starburst galaxies.

description: Riassunto - Le punte sbieche o a taglio obliquo in osso sono presenti in diversi siti eneolitici italiani dell’Italia centro-settentrionale, frequentemente in contesti funerari. Solitamente sono ricavate da tibie o da metapodi di piccoli artiodattili. Ne sono state individuate diverse tipologie: si differenziano, infatti, per la scelta del supporto, per le tecniche di lavorazione, per la lunghezza dello strumento e dello sbieco e per la presenza o meno dell’epifisi. Ci sono, inoltre, sia punte utilizzate sia non utilizzate, come quelle di Casale del Dolce che sembrano avere un uso “rituale”. Il presente contributo si focalizza sulle due punte sbieche provenienti dalle sepolture delle tombe 14 e 15 della necropoli di Selvicciola, associate ad individui di sesso maschile. Queste hanno diverse dimensioni e caratteristiche e sono riferibili a due tipi diversi. L’analisi delle tracce di lavorazione ha permesso di ricostruire le varie fasi della loro realizzazione e di riconoscere l’utilizzo di strumenti metallici per il sezionamento della diafisi dell'osso su una e per la rifinitura su entrambe. Le due punte sbieche di Selvicciola differiscono, una in parte e l’altra in maniera più evidente, dal “tipo Casale del Dolce”, che risulta il più elaborato nell'insieme Eneolitico italiano.

Summary - Typological and technological analysis of the “punte sbieche” in bone from the Eneolithic necropolis of Selvicciola, Ischia di Castro (Viterbo).

 The “punte sbieche” or oblique/angled points made of bone are present in several Eneolithic funerary contexts of the central-northern Italy. Usually, the points were obtained from tibiae or metapodials of small artiodactyls. Different types of points have been identified, according to the choice of the support, the processing techniques, the length and the obliqueness of the tool, and in reference to the presence/absence of the epiphysis. The angled points were found to be both used and not used, the latter being e.g. present in the burial at Casale del Dolce, thus suggesting their use in rituals. The present contribution focuses on the two “punte sbieche” found in the male burials 14 and 15 at the necropolis of La Selvicciola.The points vary considerably in size and can be attributed to two different types. The surface analysis allowed us to reconstruct the manufacturing process. It has been possible to identify the traces of metal tools used for cutting the diaphysis of the bone (in one of the specimens) and for finishing the tools (in both specimens). The two "punte sbieche" of Selvicciola substantially differ from those of Casale del Dolce. The latter are indeed the most sophisticated "punte sbieche" found in Italy during the Eneolithic.

description: H$α$ blobs are off-galaxy emission-line regions with weak or no optical counterparts. They are mostly visible in H$α$ line, appearing as concentrated blobs. Such unusual objects have been rarely observed and studied, and their physical origin is still unclear. We have identified 13 H$α$ blobs in the public data of MaNGA survey, by visually inspecting both the optical images and the spatially resolved maps of H$α$ line for $\sim 4600$ galaxy systems. Among the 13 H$α$ blobs, 2 were reported in previously MaNGA-based studies and 11 are newly discovered. This sample, though still small in size, is by far the largest sample with both deep imaging and integral field spectroscopy. Therefore, for the first time we are able to perform statistical studies to investigate the physical origin of H$α$ blobs. We examine the physical properties of these H$α$ blobs and their associated galaxies, including their morphology, environments, gas-phase metallicity, kinematics of ionized gas, and ionizing sources. We find that the H$α$ blobs in our sample can be broadly divided into two groups. One is associated with interacting/merging galaxy systems, of which the ionization is dominated by shocks or diffuse ionized gas. It is likely that these H$α$ blobs used to be part of their nearby galaxies, but were stripped away at some point due to tidal interactions. The other group is found in gas-rich systems, appearing as low-metallicity star-forming regions that are visually detached from the main galaxy. These H$α$ blobs could be associated with faint disks, spiral arms, or dwarf galaxies.

description: Riassunto - La tomba femminile numero 199 di Guardia Perticara (Potenza), datata ai primi decenni dell’VIII secolo a.C., ha restituito un ricco corredo funerario ed un’anforetta - kantharos ad impasto contenente un numero considerevole di reperti faunistici. Il campione consta di 245 frammenti ossei, nella maggior parte dei casi integri. Ben 230 esemplari sono stati determinati dal punto di vista anatomico e tassonomico. Le analisi hanno evidenziato la presenza di rospo, lucertola e toporagno: Bufo viridis, Bufo bufo, Bufo sp., Podarcis sp. e Sorex gr. araneus.

I resti di rospo rappresentano ben il 99% del campione (227 esemplari) mentre toporagno e lucertola sono una presenza sporadica. Sebbene in altri contesti archeologici i taxa rinvenuti siano stati spesso attribuiti a cause naturali, le evidenze rilevate per il caso in esame sembrano mostrare un accumulo intenzionale. Inoltre, non bisogna sottovalutare l’uso terapeutico di questi animali. In epoca romana, Plinio ne cita l’utilizzo come rimedio per numerosi mali.

Summary - Ritual toads in an Enotrian burial (early Iron Age)

The female burial number 199 of Guardia Perticara (Potenza-Italy) is dated back to the first decades of the 8th century B.C.. The rich grave goods include a small hand-shaping amphora-kantharos- filled up with several faunal remains.  The sample is composed of 245 specimens, most complete. The 230 identified specimens include: Bufo viridis, Bufo bufo, Bufo sp., Podarcis sp. and Sorex gr.araneus.

Toads represent 99% of the sample (227 specimens). Podarcis sp. and Sorex gr.araneus are sporadic. Although, in other archaeological contexts these taxa are usually considered intrusive, the high numbers from the burial of Guardia Perticara indicate ritual practices. Worth of mention is the therapeutic use of toads. In fact Pliny quotes them as a remedy to several ills in the Roman period.

description: This paper examines the issue of incentive-compatibility within environmental stewardship schemes where incentive payments to farmers to provide environmental goods and services are based on foregone agricultural income. The particular focus of the paper is on the role of land heterogeneity, whether in terms of agricultural value or environmental value, in leading to divergences between the actual and the socially optimal level of provision of environmental goods and services. It is shown that such goods and services are systematically over or under-provided depending on the characteristics of land heterogeneity both within and between landscape regions. It is therefore concluded that incentive payments should be based on social willingness-to pay for the provision of environmental goods and services.

description: A phenomenological model for the asymmetric giant magnetoimpedance (GMI) in field-annealed amorphous ribbons is developed. The effect of a surface crystalline layer on the GMI response is described in terms of an effective bias field appearing due to a coupling between the crystalline layer and amorphous phase. It is shown that the presence of the bias field changes drastically the GMI profile. At low frequencies, the domain-walls motion leads to a steplike change in the GMI response. At high frequencies, the domain-walls motion is damped, and the GMI profile exhibits asymmetric two-peak behavior. The calculated dependences are shown to be in a qualitative agreement with results of experimental studies of the asymmetric GMI in field-annealed Co-based amorphous ribbons.

description: After more than a decade in opposition, the win by the Australian Labor Party (ALP) at the 2007 Federal Election focuses attention on their pre-election policies. The paper summarises ALP pre-election policies for primary industries, including the resources and seafood sectors; indicates program and policy funding where it is clearly indicated in the policy papers, and commences an interpretation of the implications and opportunities that may develop as the new government proceeds to discuss its policies and their implementation. A major shift in the context for all primary industries policies to 'climate change', irrespective of whether the component policies appear to be little changed is articulated. The detail of climate change policy awaits the Climate Change Review by Professor Ross Garnaut in mid-2008. The immediate implications and opportunities for all specific policies is that they need to be viewed through the new and overarching lens of 'adapting to climate change'.

description: The interaction of supersonic laser-generated plasma jets with a secondary gas target was studied experimentally. The plasma parameters of the jet, and the resulting shock, were characterized using a combination of multi-frame interferometry/shadowgraphy, and X-ray diagnostics, allowing for a detailed study of their structure and evolution. The velocity was obtained with an X-ray streak camera, and filtered X-ray pinhole imaging was used to infer the electron temperature of the jet and shock. The topology of the ambient plasma density was found to have a significant effect on the jet and shock formation, as well as on their radiation characteristics. The experimental results were compared with radiation hydrodynamic simulations, thereby providing further insights into the underlying physical processes of the jet and shock formation and evolution.

description: We report on the production of a large area, shallow, sky survey, from XMM-Newton slews. The great collecting area of the mirrors coupled with the high quantum efficiency of the EPIC detectors have made XMM-Newton the most sensitive X-ray observatory flown to date. We use data taken with the EPIC-pn camera during slewing manoeuvres to perform an X-ray survey of the sky. Data from 218 slews have been subdivided into small images and source searched. This has been done in three distinct energy bands; a soft (0.2-2 keV) band, a hard (2-12 keV) band and a total XMM-Newton band (0.2-12 keV). Detected sources, have been quality controlled to remove artifacts and a catalogue has been drawn from the remaining sources. A 'full' catalogue, containing 4710 detections and a 'clean' catalogue containing 2692 sources have been produced, from 14% of the sky. In the hard X-ray band (2-12 keV) 257 sources are detected in the clean catalogue to a flux limit of 4x10^-12 ergs/s/cm2. The flux limit for the soft (0.2-2 keV) band is 6x10^-13 ergs/s/cm2 and for the total (0.2-12 keV) band is 1.2x10^-12 ergs/s/cm2. The source positions are shown to have an uncertainty of 8" (1-sigma confidence).

description: Trusting in others and reciprocating that trust with trustworthy actions are crucial to successful and prosperous societies. The Trust Game has been widely used to quantitatively study trust and trustworthiness, involving a sequential exchange between an investor and a trustee. The deterministic evolutionary game theory predicts no trust and no trustworthiness whereas the behavioural experiments with the one-shot anonymous Trust Game show that people substantially trust and respond trustworthily. To explain these discrepancies, previous works often turn to additional mechanisms, which are borrowed from other games such as Prisoner's Dilemma. Although these mechanisms lead to the evolution of trust and trustworthiness to an extent, the optimal or the most common strategy often involves no trustworthiness. In this paper, we study the impact of asymmetric demographic parameters (e.g. different population sizes) on game dynamics of the Trust Game. We show that, in weak-mutation limit, stochastic evolutionary dynamics with the asymmetric parameters can lead to the evolution of high trust and high trustworthiness without any additional mechanisms in well-mixed finite populations. Even full trust and near full trustworthiness can be the most common strategy. These results are qualitatively different from those of the previous works. Our results thereby demonstrate rich evolutionary dynamics of the asymmetric Trust Game.

Dallo scavo svoltosi fra il 2009 e il 2010 sono emersi tre ambienti, di cui uno di epoca protostorica e due di epoca romana imperiale. I resti faunistici in esame sono pertinenti unicamente alla fase romana. Per la maggior parte si tratta di specie domestiche, con prevalenza di bovini e ovicaprini sui suini; rilevante fra le specie selvatiche la presenza del cervo. Compaiono in piccole quantità frammenti di cane, equino e molluschi marini.

Summary - Faunal remains of the Roman settlement adjacent to the nuraghe Talia, Olmedo (Northern Sardinia)

On occasion of the construction of a new road from Sassari and Alghero to the airport, a salvage excavation in the territory of Olmedo was undertaken by the archaeological Superintendence as the area cut by the road was well known for the presence of the “Nuraghe Talia” and the roman baths. During the 2009 and 2010 campaigns, three rooms were discovered: one dated to proto-historic period while the other two can be attributed to the Roman imperial age. The faunal remains under study pertain only to the Roman age. They consist mainly of domestic species. Cattle and sheep/goat prevail over pigs while amongst the wild species, red deer is particularly abundant. Small numbers of dog and equine fragments, and marine molluscs have also been identified.

description: We review the underpinnings of the standard Newton-Einstein theory of gravity, and identify where it could possibly go wrong. In particular, we discuss the logical independence from each other of the general covariance principle, the equivalence principle and the Einstein equations, and discuss how to constrain the matter energy-momentum tensor which serves as the source of gravity. We identify the a priori assumption of the validity of standard gravity on all distance scales as the root cause of the dark matter and dark energy problems, and discuss how the freedom currently present in gravitational theory can enable us to construct candidate alternatives to the standard theory in which the dark matter and dark energy problems could then be resolved. We identify three generic aspects of these alternate approaches: that it is a universal acceleration scale which determines when a luminous Newtonian expectation is to fail to fit data, that there is a global cosmological effect on local galactic motions which can replace galactic dark matter, and that to solve the cosmological constant problem it is not necessary to quench the cosmological constant itself, but only the amount by which it gravitates.

Distiller’s grains are rapidly becoming important livestock feed ingredient sources. However, little public market information is available on distiller’s grain. This study determines spatial and temporal price relationships among distiller’s grain markets. Results indicate spatial distiller’s grain markets operate somewhat independently suggesting potential arbitrage opportunities and indicating distiller’s grain markets are information starved. Furthermore, available futures markets are not viable price risk transfer tools for distiller’s grains.

description: Riassunto - Nel riempimento dell’edificio ecclesiastico rinvenuto all’interno del castello di Santa Severa, a nord di Roma, sono stati rinvenuti 1082 elementi ossei interi e frammentati di specie avicole, di cui è stato possibile determinarne la specie di appartenenza per il 65 % circa. Questi reperti denotano un discreto consumo di uccelli da parte della popolazione che abitava il borgo medievale nel XIII e XIV sec. La maggior parte dei resti determinati (90%) indica che nel borgo molto probabilmente era praticato l’allevamento di animali da cortile (pollame e columbidi). Il restante 10%  appartiene a specie selvatiche che possono esser state oggetto di caccia per il loro interesse alimentare (oche, fagiano, starna) o che possono aver frequentato occasionalmente il castello (gabbiano tridattilo, gabbiano reale, cornacchia, allocco, chiurlo maggiore). Le specie presenti consentono di tracciare un quadro delle pratiche di sfruttamento delle risorse avicole all’interno del borgo durante il basso medioevo, e di ricostruire, anche   sulla scorta dell’analisi dei resti dei mammiferi selvatici, le condizioni ambientali delle aree limitrofe al castello di Santa Severa, dove è evidente la presenza nel periodo in esame di zone umide in cui si fermavano a svernare anche uccelli di passo.

Summary - The birds in the Castle of Santa Severa (Rome) during the Middle Ages (13th - 14th century): palaeoeconomic and environmental preliminary results

Inside the deposits of the religious building identified inside the Castle of Santa Severa, North of Rome, 1082 complete and fragmented bird bone specimens were recovered. Species identification was possible for 65% of them.. These findings reveal that birds were consumed frequently by the population living in the medieval village during the 13th and 14th centuries.
Most of the identified remains (90%) indicate that courtyard animals (poultry and Columbidae) were bred in the village. The remaining 10% can be attributed both to hunting (brent goose, geese, partridge) and to the occasional presence of wild birds (kittiwake, herring gull, crow, owl, Eurasian curlew) in the castle. The species identified helped to outline bird exploitation practices in the village during the Late Middle Ages. It also aided, along with the analysis of wild animals, in the reconstruction, of the environmental conditions of areas surrounding the castle of Santa Severa. It is evident that during the concerned period, wetlands were present where migratory birds also stopped during winter.

description: The paper studies the system of a rigid body interacting dynamically with point vortices in a perfect fluid. For arbitrary value of vortex strengths and circulation around the cylinder the system is shown to be Hamiltonian (the corresponding Poisson bracket structure is rather complicated). We also reduced the number of degrees of freedom of the system by two using the reduction by symmetry technique and performed a thorough qualitative analysis of the integrable system of a cylinder interacting with one vortex.

description: This paper examines the shifting influence of household characteristics and telecommunications infrastructure on the residential broadband adoption decision for Oklahoma residents between 2003 and 2006. In particular, the spread of wired telecommunications infrastructure (namely cable Internet and Digital Subscriber Lines (DSL)) is examined, along with the effect that this diffusion has had on broadband access rates. The data indicates that the gap in broadband access rates between rural and urban areas has remained relatively constant over this period despite increased levels of cable and DSL throughout the state. In addition, an inter-temporal decomposition shows that the increasing levels of infrastructure are not the dominant cause of higher broadband rates over time. Instead, shifting returns to specific characteristics (namely income) are found to be the primary contributors.

description: Rex Richards was renowned for his research in the field of nuclear magnetic resonance (NMR). Very early on, in the late 1940s, when NMR was in the domain of physicists, he foresaw that the technique might play an important role in chemistry. He embarked on a highly successful research career in which he combined the design and development of new NMR spectrometers with novel applications, initially in chemistry and subsequently in the biological sciences. One major outcome was the establishment of the Oxford Enzyme Group's NMR research programme. Another was the development of 31P NMR spectroscopy as a non-invasive method of probing the biochemistry of intact biological tissue. Rex was an outstanding teacher and mentor. He also had highly impressive administrative skills, as recognized through successive appointments at the University of Oxford as head of the Physical Chemistry Department, then warden of Merton College and finally vice-chancellor. He was subsequently appointed director of the Leverhulme Trust and became widely respected in the arts world, as reflected by his remarkable array of committee memberships at the National and Tate Galleries.

description: Detection template families (DTFs) are built to capture the essential features of true gravitational waveforms using a small set of phenomenological waveform parameters. Buonanno, Chen, and Vallisneri [Phys. Rev. D 67, 104025 (2003)] proposed the ``BCV2'' DTF to perform computationally efficient searches for signals from precessing binaries of compact stellar objects. Here we test the signal-matching performance of the BCV2 DTF for asymmetric--mass-ratio binaries, and specifically for double--black-hole binaries with component masses (m1,m2): (6~12Msun, 1~3Msun), and for black-hole--neutron-star binaries with component masses (m1,m2) = (10Msun, 1.4Msun); we take all black holes to be maximally spinning. We find a satisfactory signal-matching performance, with fitting factors averaging between 0.94 and 0.98. We also scope out the region of BCV2 parameters needed for a template-based search, we evaluate the template match metric, we discuss a template-placement strategy, and we estimate the number of templates needed for searches at the LIGO design sensitivity. In addition, after gaining more insight in the dynamics of spin--orbit precession, we propose a modification of the BCV2 DTF that is parametrized by physical (rather than phenomenological) parameters. We test this modified ``BCV2P'' DTF for the (10Msun, 1.4Msun) black-hole--neutron-star system, finding a signal-matching performance comparable to the BCV2 DTF, and a reliable parameter-estimation capability for target-binary quantities such as the chirp mass and the opening angle (the angle between the black-hole spin and the orbital angular momentum).

description: Riassunto - Le indagini archeologiche condotte nel 2010 nell’Area B del complesso santuariale di Podere Ortaglia-Peccioli (Pisa), strutturato intorno ad un grande edificio templare eretto in età Tardo-Arcaica hanno portato al rinvenimento eccezionale di uno scheletro integro di un cinghiale sacrificato, inquadrabile cronologicamente al secondo quarto del V sec. a.C. Le valutazioni effettuate sullo scavo ed in laboratorio hanno consentito di stabilire che il soggetto, un animale giovane e sano era stato volontariamente sepolto all’interno della fossa rituale. Le informazioni fornite da questa deposizione vanno a completare quelle relative alla sfera rituale, cultuale ed economica del sito.

Summary - Archaeological evidence of sacrificial deposition of a wild boar (Sus scrofa) in Podere Ortaglia, Peccioli (Pisa, Tuscany)

Archaeological investigations conducted in 2010 in the “Area B” of the temple-shrine complex built during the Late Archaic period in Podere Ortaglia, Peccioli (Pisa,Tuscany) revealed the perfectly intact skeleton and sacrificial remains of a wild boar dated at the second quarter of the 5th century B.C. In the second half of the 4th  century B.C, the temple was destroyed by fire and many of the materials related to it, such as building materials and common objects usually used for daily life and ritual practices, were buried in a large artificial pit adjacent to the temple. Site field screening of the excavation, together with laboratory analysis, have allowed to establish that the subject, a young large-sized and healthy animal, was deliberately buried in a sacrificial pit. The information provided in this study is intended to complement the research being conducted on social, economic and spiritual practices held in that area.

description: Riassunto - Il presente lavoro ha come oggetto di studio l’analisi archeozoologica condotta sul campione faunistico proveniente dalla Necropoli e dalla Chiesa paleocristiana di Vaste (Lecce), piccolo comune del Salento. La particolarità della necropoli è data dalla presenza, sulle lastre di copertura dei sarcofagi, di piccole cavità scavate nella pietra o realizzate con la malta, collocate in corrispondenza della testa dei defunti, ed evidentemente funzionali al rito del refrigerium.
L’analisi dei resti faunistici ha dimostrato come i primi cristiani scegliessero come alimenti da offrire e condividere nel pasto sacro con il defunto, gli animali domestici di cui disponevano in numero maggiore o che comunque rientravano nella loro dieta; principalmente caprovini, suini, pollame, ma anche pesce e uova.

Summary - Evidence of practices of refrigerium in early Christian necropolis of Vaste (Lecce)
This paper concerns the analyses carried out on the archaezoological remains from the Necropolis and early Christian Church of Vaste (Lecce), a small town of Salento. The special feature of the Necropolis is the presence of, on the cover plates of the sarcophagi, small cavities carved out in the stone or made with mortar, placed at the head of the deceased, and apparently functional in the ritual of refrigerium.

The analysis of the faunal remains showed that the early Christians chose domestic animals as food to offer and share in the sacred meal with the deceased. These animals such as sheep and goats, pigs, chicken, fish and eggs were most available or were part of their diet.

description: We aim to understand cloud formation in substellar objects. We combined the non-equilibrium, stationary cloud model of Helling, Woitke & Thi (2008; seed formation, growth, evaporation, gravitational settling, element conservation) with the general-purpose model atmosphere code PHOENIX (radiative transfer, hydrostatic equilibrium, mixing length theory, chemical equilibrium) in order to consistently calculate cloud formation and radiative transfer with their feedback on convection and gas phase depletion. We calculate the complete 1D model atmosphere structure and the chemical details of the cloud layers. The DRIFT-PHOENIX models enable the first stellar atmosphere simulation that is based on the actual cloud formation process. The resulting (T,p) profiles differ considerably from the previous limiting PHOENIX cases DUSTY and COND. A tentative comparison with observations demonstrates that the determination of effective temperatures based on simple cloud models has to be applied with care. Based on our new models, we suggest a mean Teff=1800K for the L-dwarf twin-binary system DENIS J0205-1159 which is up to 500K hotter than suggested in the literature. We show transition spectra for gas-giant planets which form dust clouds in their atmospheres and evaluate photometric fluxes for a WASP-1 type system.

Canadian energy use and greenhouse gas emissions in the 1980’s and 1990’s : decomposition of changes, extrapolation of trends and comparison to other oecd countries
Creators: name: Herbert, Deborah Marie
Publisher: name: University of British Columbia

description: This thesis examines energy use in Canada in the early to mid-1980's to mid-1990's to investigate what factors caused energy use and greenhouse gas emissions to rise. Trends from this period in energy use and fuel mix are also projected to the years 2000 and 2010. In addition, Canada is compared to 12 other OECD countries to determine whether differences in climate, geography and industrial structure account for differences in absolute and per capita energy use between Canada and these countries. Changes in activity were the main drivers of the increases in energy use and greenhouse gas emissions in the 1980's and 1990's. This influence was partially offset by declines in energy intensity. Structural changes tended to have a less profound impact. Based on trends from this period, both energy use and greenhouse gas emissions will continue rising. More positively, there already are trends towards less greenhouse gas-intensive fuels in some sectors. Climate, geography and industrial structure do not account for differences in per capita energy use between Canada and other industrialized countries. The one exception is the United States. This implies that, with the exception of the U.S., Canada is relatively less energy efficient than other industrialized countries.
