What we know about Migration within Canada — a Selective Review and Agenda for Future Research

The past ten years have witnessed an explosion of published research on migration. A series of review papers on the state of the knowledge may be worthwhile at this time. With specific reference to internal migration in Canada, this paper is offered as a part of the review exercise. In a short paper it is necessary to be very selective and cover topics with a broad brush. This comment applies here particularly to the analytical research on the spatial pattern of migration. Firstly, I shall identify some major questions for migration research. Then I shall summarise some of the partial answers to the questions that have emerged so far in the work on Canada. Finally, I will point up specific areas in which diminishing marginal returns on future research expenditures seem imminent, and other areas where much virgin territory appears to be ahead of migration analysts.

Characteristics of layer-by-layer ZnO nanoparticles thin films prepared with different deposition layer

Layer-by-layer ZnO nanoparticles thin films were deposited using sol-gel spin coating technique. Zinc acetate dihydrate, 2-methoxyethanol and monoethanolamine were used in the ZnO solution. Different numbers of film layers were employed to study their effects to the physical, electrical and optical properties of the thin films. XRD patterns showed that the films were single crystalline with highly c-axis orientation for films with higher numbers of deposition layers. Morphology studies revealed that the grain sizes increased with the number of layers. Resistivity of the film decreased with the increased number of layers with minimum value of 15.5 Ω. cm given by 6 layers film. The PL spectra exhibit highest UV emission for 6 layers film due to high crystalline quality of the thin film.
An Analysis of the Marginal Value of Electricity Transmission Lines in the Dispatch: Possible Applications

The marginal value of transmission lines in the dispatch is widely used in the literature and has relevant practical applications related to planning the expansion of the transmission grid and computing the remuneration of merchant lines. This paper presents a general formulation of the marginal value of a line in the dispatch that highlights the dependence of this value on the link between line admittance and capacity. We discuss the value of a line according to marginal principles following a general approach and prove that only if the admittance of a line can be expressed as a linear function of its capacity, or when admittance and capacity can be deemed independent, is this value equal to the product of the difference between marginal electricity prices at both ends of the line and the flow through this line. Afterwards, we show that under a set of stylized conditions the remuneration of efficient network investments according to their marginal value in the dispatch should result in an exact recovery of their cost. Finally, we compute the marginal value of lines in a stylized, though representative, system for several relationships between line capacities and admittances to illustrate the theoretical results obtained.
Acute hypoxia and hypoxic exercise induce DNA strand breaks and oxidative DNA damage in humans

The present study investigated the effect of a single bout of exhaustive exercise on the generation of DNA strand breaks and oxidative DNA damage under normal conditions and at high‐altitude hypoxia (4559 meters for 3 days). Twelve healthy subjects performed a maximal bicycle exercise test; lymphocytes were isolated for analysis of DNA strand breaks and oxidatively altered nucleotides, detected by endonuclease III and formamidipyridine glycosylase (FPG) enzymes. Urine was collected for 24 h periods for analysis of 8‐oxo‐7,8‐dihydro‐2′‐deoxyguanosine (8‐oxodG), a marker of oxidative DNA damage. Urinary excretion of 8‐oxodG increased during the first day in altitude hypoxia, and there were more endonuclease III‐sensitive sites on day 3 at high altitude. The subjects had more DNA strand breaks in altitude hypoxia than at sea level. The level of DNA strand breaks further increased immediately after exercise in altitude hypoxia. Exercise‐induced generation of DNA strand breaks was not seen at sea level. In both environments, the level of FPG and endonuclease III‐sensitive sites remained unchanged immediately after exercise. DNA strand breaks and oxidative DNAdamage are probably produced by reactive oxygen species, generated by leakage of the mitochondrial respiration or during a hypoxia‐induced inflammation. Furthermore, the presence of DNA strand breaks may play an important role in maintaining hypoxia‐induced inflammation processes. Hypoxia seems to deplete the antioxidant system of its capacity to withstand oxidative stress produced by exhaustive exercise. —Møller, P., Loft, S. , Lundby, C. , Olsen, N. V.

A comparison of two canopy conductance parameterizations to quantify the interactions between surface ozone and vegetation over Europe

[1] The effect of air pollution on vegetation and the consequent changes in atmospheric chemistry are largely under-investigated; a new generation of chemical transport models fully coupled with complex land surface models is needed to better represent the feedbacks between vegetation and atmospheric chemistry. In this context, we coupled at high spatial resolution (30 km) the chemistry transport model CHIMERE with the land surface model ORCHIDEE to study the regional impact of tropospheric ozone on Euro-Mediterranean vegetation and the consequent changes in biogenic emission and ozone dry deposition owing to modifications in canopy conductance and LAI due to the ozone stress on vegetation. Results for the year 2002 show that the effect of tropospheric ozone on vegetation leads to a significant reduction of about 23% in the annual gross primary production, followed by a reduction in leaf area index. In addition, results show that CHIMERE does not correctly reproduce the activity of evergreen forests, grassland and crops during winter and fall, and consequently the dry deposition velocity is affected by this wrong pattern. On the other hand, in the coupled model, we have a better representation of vegetation activity during cold months, and the general performance of the model is improved compared to local site observations.
Movement compatibility for frontal controls with displays located in four cardinal orientations

Strength and reversibility of direction-of-motion stereotypes and response times are presented for different configurations of horizontal, vertical and rotary controls with horizontal, vertical and circular displays. Measures of the strength and reversibility of stereotypes were used to analyse the effects of direction of turn instruction (clockwise/anticlockwise; up/down; left/right), display orientation (North; East; South; West) and hand side (left/right) on movement compatibility. A number of acceptable display/control arrangements were identified for displays in each of the North, East, South and West orientations relative to the operator. For the horizontally moving control, the Worringham and Beringer principle was found to identify display/control arrangements having both high stereotype strength and high reversibility. Vertically moving controls are excellent with vertical displays but poor with horizontal and circular displays. Rotary controls have high stereotype strength and reversibility with both horizontal and circular displays (with the indicator at the 12 o'clock position). Statement of Relevance:Design of display/control arrangements requires a strong relationship between operator's expectancies and the response of a device to control inputs. The present research fills in gaps for stereotypes where data are not available, in particular where the operator is not seated facing a display directly to the front.
Open innovation and firms performance: state of the art and empirical evidences from the bio-pharmaceutical industry

The research presented in this paper explores the effect of inbound, outbound and coupled open innovation practices on firms' performances in the biopharmaceutical industry. Specifically, although existing researches on open innovation effectiveness have separately investigated the effect of open innovation practices on innovation and financial performance, this study evaluates the concurrent effect of these practices on both such performance dimensions in a single framework. We state the importance for a manager to explore concurrently the influence of specific open innovation practices both on innovation and economic-financial performance. We empirically test our framework on a sample of 120 companies listed on the NASDAQ biotechnology index.
Soldiering on: Exploring the role of humour as a disciplinary technology in the military

This article considers the role of humour as a disciplinary technology. Using the British military as an organizational context, and drawing on data from the published memoirs of recently serving military personnel, the article makes three arguments in this regard. First, it is argued that the disciplinary apparatus of the military, as an example of a rule-bound and hierarchical organizational structure, creates the conditions that allow for a controlled form of resistance (through humour) to be enacted by organizational subjects; but ultimately, such acts work to serve the requirements of the organization. Second, it is argued that humour contributes to the establishing of social cohesion through disciplinary practices of inclusion and exclusion and the drawing of lines of normalization, both at the local level and at a wider institutional level. Third, it is argued that humour permeates the power relations that structure organizational life: both those governed by rank and position and those that arise through the modes of self-regulation through which much organizational disciplining is enacted. This article concludes by drawing attention to the dialectic and dynamic nature of humour while also offering suggestions for the wider applicability of the disciplinary role of workplace humour.
Topological graph kernel on multiple thresholded functional connectivity networks for mild cognitive impairment classification

Recently, brain connectivity networks have been used for classification of Alzheimer's disease and mild cognitive impairment (MCI) from normal controls (NC). In typical connectivity‐networks‐based classification approaches, local measures of connectivity networks are first extracted from each region‐of‐interest as network features, which are then concatenated into a vector for subsequent feature selection and classification. However, some useful structural information of network, especially global topological information, may be lost in this type of approaches. To address this issue, in this article, we propose a connectivity‐networks‐based classification framework to identify accurately the MCI patients from NC. The core of the proposed method involves the use of a new graph‐kernel‐based approach to measure directly the topological similarity between connectivity networks. We evaluate our method on functional connectivity networks of 12 MCI and 25 NC subjects. The experimental results show that our proposed method achieves a classification accuracy of 91.9%, a sensitivity of 100.0%, a balanced accuracy of 94.0%, and an area under receiver operating characteristic curve of 0.94, demonstrating a great potential in MCI classification, based on connectivity networks. Further connectivity analysis indicates that the connectivity of the selected brain regions is different between MCI patients and NC, that is, MCI patients show reduced functional connectivity compared with NC, in line with the findings reported in the existing studies.

Speaking of the weather: Detection of meteorological influences on sentiment within social media

Weather occurs in everyday discussion, in every language around the globe. Many people believe that weather does impact our mood and behavior. However, to what degree does this hold? We investigate a collection of weather data and link them to social media feeds. Our work focuses on the comparison of three popular sentiment metrics (previous work focused on one metric) connected to commonly used weather measures with precise geographical linking. Our geographical linking method boosts confidence in results compared with previous work. Additionally, our comparison of three sentiment metrics demonstrates how results can easily be misrepresented when using analysis with a single sentiment metric only. We adopt a state-of-the-art Twitter sentiment classifier and a ‘weather classifier’ evaluated on gold standard test sets and live Twitter data. With the evaluated classification models, a stream of over 30 million live tweets is classified and linked to weather data collected from the same period at over 2,000 weather stations. Our analysis indicates a significant link between sentiment measures and several measures of weather, suggesting that human behavior in the domain of social media is impacted by external factors such as weather.
La ségrégation sociale a-t-elle augmenté ? : La métropole parisienne entre polarisation et mixité

L'idee que la segregation sociale a augmente et qu'elle concerne avant tout les categories defavorisees fait partie du sens commun politique, mediatique, academique. Pourtant, l'analyse detaillee de la distribution des differentes categories sociales dans l'espace de la metropole parisienne montre que ce sont les classes superieures qui sont le plus segregees et que leur auto-segregation s'intensifie. Parmi les categories populaires, les plus segreges sont les ouvriers, dont les effectifs decroissent, alors que la plupart des categories d'employes et des professions intermediaires connaissent une segregation decroissante avec des effectifs croissants. Ces tendances generales resultent d'evolutions spatiales bien plus diversifiees que la dualisation souvent avancee. Elles se traduisent par une exclusivite accrue dans les espaces les plus bourgeois, qui s'elargissent, mais par des evolutions diversifiees des quartiers populaires ouvriers, ou l'appauvrissement social est une modalite minoritaire mais preoccupante. Si la situation de mixite sociale reste la modalite residentielle la plus frequente pour les classes moyennes et populaires, le tissu social de ces espaces est menace par la montee du chomage et de la precarite, qui affectent de facon croissante les classes moyennes elles-memes.

The neuronal chondroitin sulfate proteoglycan neurocan binds to the neural cell adhesion molecules Ng-CAM/L1/NILE and N-CAM, and inhibits neuronal adhesion and neurite outgrowth

We have previously shown that aggregation of microbeads coated with N- CAM and Ng-CAM is inhibited by incubation with soluble neurocan, a chondroitin sulfate proteoglycan of brain, suggesting that neurocan binds to these cell adhesion molecules (Grumet, M., A. Flaccus, and R. U. Margolis. 1993. J. Cell Biol. 120:815). To investigate these interactions more directly, we have tested binding of soluble 125I- neurocan to microwells coated with different glycoproteins. Neurocan bound at high levels to Ng-CAM and N-CAM, but little or no binding was detected to myelin-associated glycoprotein, EGF receptor, fibronectin, laminin, and collagen IV. The binding to Ng-CAM and N-CAM was saturable and in each case Scatchard plots indicated a high affinity binding site with a dissociation constant of approximately 1 nM. Binding was significantly reduced after treatment of neurocan with chondroitinase, and free chondroitin sulfate inhibited binding of neurocan to Ng-CAM and N-CAM. These results indicate a role for chondroitin sulfate in this process, although the core glycoprotein also has binding activity. The COOH-terminal half of neurocan was shown to have binding properties essentially identical to those of the full-length proteoglycan. To study the potential biological functions of neurocan, its effects on neuronal adhesion and neurite growth were analyzed. When neurons were incubated on dishes coated with different combinations of neurocan and Ng-CAM, neuronal adhesion and neurite extension were inhibited. Experiments using anti-Ng-CAM antibodies as a substrate also indicate that neurocan has a direct inhibitory effect on neuronal adhesion and neurite growth. Immunoperoxidase staining of tissue sections showed that neurocan, Ng-CAM, and N-CAM are all present at highest concentration in the molecular layer and fiber tracts of developing cerebellum. The overlapping localization in vivo, the molecular binding studies, and the striking effects on neuronal adhesion and neurite growth support the view that neurocan may modulate neuronal adhesion and neurite growth during development by binding to neural cell adhesion molecules.
Conversion of bone marrow mesenchymal stem cells into type II alveolar epithelial cells reduces pulmonary fibrosis by decreasing oxidative stress in rats

Pulmonary fibrosis is an irreversible chronic progressive fibroproliferative lung disease, which usually has a poor prognosis. Previous studies have confirmed that the transplantation of bone marrow mesenchymal stem cells (MSCs) significantly reduces lung damage in a number of animal models. However, the underlying mechanism involved in this process remains to be elucidated. In the present study, a bleomycin (BLM)-induced female Wister rat model of fibrosis was established. At 0 or 7 days following BLM administration, rats were injected into the tail vein with 5-bromo-2-deoxyuridine-labeled MSCs extracted from male Wistar rats. The lung tissue of the rats injected with MSCs expressed the sex-determining region Y gene. The level surfactant protein C (SP-C), a marker for type II alveolar epithelial cells (AEC II), was higher in the group injected with MSCs at day 0 than that in the group injected at day 7. Furthermore, SP-C mRNA, but not aquaporin 5 mRNA, a marker for type I alveolar epithelial cells, was expressed in fresh bone marrow aspirates and the fifth generation of cultured MSCs. In addition, superoxide dismutase activity and total antioxidative capability, specific indicators of oxidative stress, were significantly increased in the lung tissue of the MSC-transplanted rats (P<0.05). In conclusion, to alleviate pulmonary fibrosis, exogenous MSCs may be transplanted into damaged lung tissue where they differentiate into AEC II and exert their effect, at least in part, through blocking oxidative stress.
A Tool for Addressing Construct Identity in Literature Reviews and Meta-Analyses

The problem of detecting whether two behavioral constructs reference the same real-world phenomenon has existed for over 100 years. Discordant naming of constructs is here termed the construct identity fallacy (CIF). We designed and evaluated the construct identity detector (CID), the first tool with large-scale construct identity detection properties and the first tool that does not require respondent data. Through the adaptation and combination of different natural language processing (NLP) algorithms, six designs were created and evaluated against human expert decisions. All six designs were found capable of detecting construct identity, and a design combining two existing algorithms significantly outperformed the other approaches. A set of follow-up studies suggests the tool is valuable as a supplement to expert efforts in literature review and metaanalysis. Beyond design science contributions, this article has important implications related to the taxonomic structure of social and behavioral science constructs, for the jingle and jangle fallacy, the core of the Information Systems nomological network, and the inaccessibility of social and behavioral science knowledge. In sum, CID represents an important, albeit tentative, step toward discipline-wide identification of construct identities
User Assessment of E-negotiation Systems

A study of over 2000 students and professionals who used the inspire e-negotiation system led Vetschera, Kersten and Koeszegi to the formulation of an assessment model for Internet-based systems (AMIS). The model was used to determine factors leading to a high user acceptance of the technology exemplified by inspire. This paper presents a follow up study that uses structured equation modeling to verify AMIS and its empirical results. The focus is on the examination of the users' assessment of the system and their intention to use it, while taking info consideration its key features. In addition, the impact of gender is tested on the model to relate important differences in perceptions
