In 1907,military leader Robert Baden-Powell started the Boy Scouts Association in England as the British colonial government officers instituted Tamale village as the administrative centre of the Northern Territories Protectorate.Sam Yarney worked with Frank Collyer the European bank cashier and scoutmaster who started the Boy Scouts in the Gold Coast Colony in 1914,the year the First World War started.In 1922,Governor Gordon Guggisberg,who was brigadier general during the war was the chief scout.He reorganized the Local Boy Scouts Association in the Tamale Government School that received select boys from various schools in the Northern Territories Protectorate.The schoolboys excelled in the Standard VII and Civil Service Examinations to work with the government institutions and train as teachers and telegraphists.Arthur James Philbrick the chief scout commissioner of the Northern Territories employed Yarney as the assistant scout commissioner in the Southern Province to take on the staff of the reorganized Tamale Local Boy Scouts Association and register the 1st Tamale Troop.The scout officers subscribed to a Scout Fund to buy kit,for the schoolboys who passed the Tenderfoot Tests to buy uniforms and perform at events. 展开更多

Background: The habitat features of breeding territory have important adaptive significance for the survival and reproduction of territory holders.The Chinese Grouse(Tetrastes sewerzowi) is a rare and endemic species with rela?tively small distribution range and decreasing population trend.It is important to elucidate breeding territory habitat requirements of the Chinese Grouse for habitat management and conservation actions.Methods: Using radio?telemetry and field observations,we determined the core areas of 65 breeding territories of males.Two to three samples were selected in each core breeding territory as used sites and compared with nearby sites with no grouse occurrence using logistic regression.Results: Our model showed a high accuracy in prediction of core breeding territory used by males,which preferred stands with more small deciduous trees(0.5 m ≤ height < 5 m),more small willow trees(Salix spp.,0.5 m infl≤ height < 5 m),greater willow cover,and greater herb cover.The number of small willow trees had the great?estuence on males' core breeding territory selection.Dense shrubs were also chosen compared with unused sites Tall conifer trees was an important determinant in the distribution of Chinese Grouse at the landscape scale,and was relatively important in the univariate model,but not included in our final multivariable model.Conclusions: Male Chinese Grouse established territories at sites with abundant food resources.At the landscape scale,the Chinese Grouse occurred in alpine conifer forest.At the territory scale,small willow trees had the most important effect on males' core breeding territory selection.We suggest that the forest gaps in dense conifer for?est are important for improving the occurrence of willows and facilitating breeding territory establishment for the Chinese Grouse. 展开更多

The role of Landscape Character Assessment(LCA)at the level of territorial landscape governance spans both natural and social sciences.By analyzing the development history,research distribution,methods and applications of cutting-edge cases of LCA in China,the following conclusions are drawn:①the LCA research in China originated earlier than that in Europe,but has not yet been systematically applied to the implementation of urban and rural planning at all levels;②the fundamental theory of LCA in China has been well constructed,with three main research directions:technologyled,assessment-led,and assessment combined with other theories;③the development of LCA in rural areas is more mature than in urban areas,but the progress of research is uneven across regions;④the current research presents significant“bottom-up”academic characteristics,and there is an urgent need for government decision-making authorities and academia to jointly promote a“top-down”standardized governance mechanism to comprehensively promote the modernization of territorial landscape governance. 展开更多

The coordinated development of urban and rural territorial systems has long been a scientific issue of concern in geography and socioeconomic development in China.Based on Territorial Function Theory,this paper establishes a theoretical framework to support the coordinated development of urban and rural territorial systems,analyzes the trend of functional evolution,discusses the impact of efficient allocation and orderly element flow on system equivalence development,and puts forward approaches and policy suggestions for equilibrium development in the future.The main conclusions are as follows:(1)The evolution of urban and rural territorial functions has experienced four stages:rural to rural,rural to urban transition,rural to urban,and urban to urban.In this process,territorial functions have been developed to be hierarchical and advanced.(2)Functional evolution enables urban and rural comparative advantages to be transformed from value difference to value equivalence.Increasing the flow intensity and reconstructing the flow space have become the necessary conditions for the coordination of development.(3)Land is the most important resource in China,and land system reform is the key to achieving equivalence development of urban and rural territorial systems,thereby determining the future equilibrium development of the two systems. 展开更多

Despite the widely accepted view that planted forests are valuable habitat for wildlife species,there is a lack of empirical evidence showing the suitability of this novel habitat,especially in relation to plantations of exotic tree species.Furthermore,little is known about the effects of forest management on the ecology and dynamics of wild populations in the Neotropics.During the breeding season,the migrant flycatcher White-crested Elaenia is the most abundant bird species in forested landscapes in Chile.For several years we have studied different aspects of these artificial forests in the coastal range of south-central Chile as habitat for the species,particularly in contrast to the native forest.In general,our results indicate that plantation forests offer a poorer quality habitat,where the density of the species tends to be lower than in the native forest,although a significant edge effect suggests that its quality can be mitigated by planting as a matrix mosaic with native forest.Furthermore,compared to native forests,populations in plantations contained a higher proportion of younger adult individuals maintaining larger territories,and showing poorer body condition.We suggest that these differences could also have an impact on the birds'longevity and survival. 展开更多

Madness has attracted and frightened for centuries,and talking about this means discussing how this diversity was built and managed in different social contexts and historical periods.Not all societies have had,and still have,the same relationship with madness.It is only with the affirmation of the Modern State,and of Capitalism,that the idea of“normality”indispensable to be able to conceive diversity as something dangerously distant and different from the norm takes over.In our post-modern society,people with mental illness in Italy can resort to specialists and social-health services.But the heterogeneous answers given after the approval of law 180 appear to be increasingly diversified.In this research,much attention will be paid to how the social and health services,located in different areas of Italy(Messina,Rome,Trento)face the current growing risk of social,housing and economic isolation of these fragile subjects.The aim of the research is to explore the possibility of a new relationship between the social-health service and the local community.On the one hand,research investigates what the contribution of the services could be.On the other what the spaces of protagonism and participation of the community could be in inclusion process account.In order to better understand the differences between these two dimensions,a qualitative research approach was chosen through the conduct of in-depth interviews.In this way it was possible to investigate:(1)the partial representations characteristic of the single individual,family members,operators and stackholders in general;(2)the services around the topic dealt with is articulated.From the first results of the research it emerges that the territory can no longer be considered as an abstract entity,but becomes the social space within which the construction of a new community welfare can and must take place. 展开更多

The establishment of the territorial spatial plan system is an important space reform act to meet the new era in China.The reform of territorial spatial plans according to classification is in line with the characteristics of China’s current territorial spatial administration and urban development.At present,China’s provincial and municipal territorial spatial plans have been publicized,and county-level territorial spatial plans are being approved one after another,while the compilation of township-level territorial spatial plans is being carried out in an orderly manner.In this paper,based on the historical background of the establishment of territorial spatial plan system integrating“multiple plans”,the background of territorial spatial plans and the important role of county-level territorial spatial plans were first elaborated,and then the progress of the compilation of county-level territorial spatial plans in Jiangxi Province was sorted out.Finally,the problems existing in the compilation were discussed,and corresponding suggestions were put forward to provide a certain reference for the construction of a scientific and reasonable territorial spatial plan system. 展开更多

The aim of this article is to strengthen and improve the collaboration between professional agents of a service that manages one of the technical processes acting on a given territory by synchronizing the spatio-temporal dimensions including all agents assembled for the task. This proposal was tested in the Lamkansa neighborhood in Casablanca, Morocco. The employed approach is based GIS resources and on systemic analysis of communication present in a territory. We were inspired by several methodological developments that carried multi-actor processes in land use planning. We focused our work on strengthening the collaboration between professionals, field agents and office agents, in the process of design and monitoring the liquid sanitation system. The device is based on geolocation and synchronous feedback of topological, geographical, and multimedia data related to the liquid sanitation network. Thanks to a geo-collaborative, participative, and motivating logic, we reduced the management costs of the network and made it faster and more efficient by equally mobilizing another type of non-specialized actors (the inhabitants). This device uses spatial and temporal dimensions to consolidate collaborative work tools through ICT and GIS technologies that thematize and exchange information collected in the field. Furthermore, this device raises great interest as it entails the concept of integration of several actors in a geo-collaborative mode while combining geomatics with communication and information sciences. 展开更多

The present study presents cytogenetics/cytology of haploidization in the origin of a new, fast growing diploid, small cell-type (F-dPCs). The sequence of events was haploid groupings of the chromosomes in normal, human metaphase cells, followed by genomic doubling to homozygousdiploidy. These events were responses to DNA replication stress fromamino acid glutamine deprivation. Importantly, these homozygous cells outgrew normal fibroblasts in 2 - 3 passages—they had gained proliferative advantage (GPA), presumably from loss (LOH) of tumor suppressor genes. They were morphologically changed cells with rounded nuclei that grew in a “streaming” growth pattern and with changed form and size of mitosis, similar to some hyperplasias. The grouping of the chromosomes in metaphase cells was asymmetric with a narrow range around the median (23) (no micro-nuclei), suggesting genetic control. The root-origin of haploidization was evidenced by maternal and paternal genomes occupying separate territories in metaphase cells, which assumedly permitted independent segregations of bichromatid chromosomes. In near-haploid ALL-L1 leukemia the loss of virtually, whole chromosomal complements was judged by SNP array analyses, as a primary event before genomic doubling to hyperdiploidy with LOH. From the present data such specific, non-random loss of chromosomes strongly suggested, a haploidization process capable of genomic doubling, as observed for the “birth” of the small, F-dPCs. This suggestion was supported by this type of leukemia being the L1-type, where L1 signifies small cells. The possibility now exists that a tumorigenic process can be initiated directly from diploid cells through haploid (near-haploid) distributed chromosomes in normal metaphase cells. This event followed by monosomic doublings to UPDs would lead to massive LOH and a return to para-diploidy, a frequent occurrence in many types of tumors. The present simple, cultural derivations of the extraordinary F-dPCs allow GPA-identification and experimental manipulations, perhaps relevant in a vaccine program. 展开更多

Diarrheal diseases have been known to cause death in many children below the age of five years,and rotavirus infection represents a major health problem in the world today,particularly in developing countries.The recent outbreak of rotavirus gastroenteritis in Samoa led to the introduction of her debut national immunization program on rotavirus vaccination for infants.Despite the introduction of anti-viral and anti-emetic drugs as of the containment approaches towards the virus,risk factors,preventive measures and public health preparedness against rotavirus infection are poorly understood in Samoa.This review aims to use available evidence on rotavirus literature to elucidate and map preventive strategies for the recently emerged rotavirus infections in Samoa.We conducted a search strategy using online medical literature databases and retrieval systems.A designated set of keywords such as rotavirus,gastroenteritis,outbreak,risk factors,containment measures,vaccination and Samoa were inserted in electronic databases to retrieve articles.The databases included Pub Med,Google Scholar,MEDLINE,Scinapse,and EBSCO host.Findings from this review addressed the impact of rotavirus infection,associated threats and other preventive measures.Introducing useful health frameworks in pursuing possible methods such as improved water quality,exclusive breast feeding,improved laboratory diagnostics and outbreak surveillance,may be essential in addressing alternate approaches towards containment of the disease in Samoa and other Pacific Island Countries and Territories. 展开更多

BACKGROUND Screening provides earlier colorectal cancer(CRC)detection and improves outcomes.It remains poorly understood if these benefits are realized with screening guidelines in remote northern populations of Canada where CRC rates are nearly twice the national average and access to colonoscopy is limited.AIM To evaluate the participation and impact of CRC screening guidelines in a remote northern population.METHODS This retrospective cohort study included residents of the Northwest Territories,a northern region of Canada,age 50-74 who underwent CRC screening by a fecal immunohistochemical test(FIT)between January 1,2014 to March 30,2019.To assess impact,individuals with a screen-detected CRC were compared to clinically-detected CRC cases for stage and location of CRC between 2014-2016.To assess participation,we conducted subgroup analyses of FIT positive individuals exploring the relationships between signs and symptoms of CRC at the time of screening,wait-times for colonoscopy,and screening outcomes.Two sample Welch t-test was used for normally distributed continuous variables,Mann-Whitney-Wilcoxon Tests for data without normal distribution,and Chi-square goodness of fit test for categorical variables.A P value of<0.05 was considered to be statistically significant.RESULTS 6817 fecal tests were completed,meaning an annual average screening rate of 25.04%,843(12.37%)were positive,629 individuals underwent a follow-up colonoscopy,of which,24.48%had advanced neoplasia(AN),5.41%had CRC.There were no significant differences in stage,pathology,or location between screen-detected cancers and clinically-detected cancers.In assessing participation and screening outcomes,we observed 49.51%of individuals referred for colonoscopy after FIT were ineligible for CRC screening,most often due to signs and symptoms of CRC.Individuals were more likely to have AN if they had signs and symptoms of cancer at the time of screening,waited over 180 d for colonoscopy,or were indigenous[respectively,estimated RR 1.1895%CI of RR(0.89-1.59)];RR 1.523(CI:1.035,2.240);RR 1.722(CI:1.165,2.547)].CONCLUSION Screening did not facilitate early cancer detection but facilitated higher than anticipated AN detection.Signs and symptoms of CRC at screening,and long colonoscopy wait-times appear contributory. 展开更多

Major function oriented zoning (MFOZ hereafter) is the guideline for optimizing the spatial pattern of regional development in China, which entails both theoretical and methodological innovation in the academic field of economic geography. This study analyzes the basic features of territorial function and puts forward a spatial equilibrium model for regional development for the first time. It argues that there exists a trend of regional convergence in the average value which indicates the comprehensive development status of any region. Based on this finding, the study illustrates that the formation of functional zone should be conducive to the narrowing of regional gap and that free flow of resources between regions is the prerequisite to spatial equilibrium. It also investigates the impact of territorial functional evolution on the process of spatial equilibrium and suggests that the maximization of benefits derived from zoning proposal is interrelative with the method of regional division and the degree of understanding towards the temporal changes of territorial function. Furthermore, this study goes on to examine the scientific foundation of several issues concerning the reconciliation between contradictory functions of development and protection, the selection of indicators and the spatial and temporal features of MFOZ. It is then probes into the rationality of achieving dual goals of efficiency and equality simultaneously through three-dimensional flow and spatial equilibrium. The paper ends with discussions on the position, implementation and coordination of MFOZ from the perspective of institutional arrangements of spatial governance including law, planning and government policy. 展开更多

Territory and territorial behavior of the Common Coot(Fulica atra) were studied in two breeding sites,Anbanghe Nature Reserve and Daqing Longfeng wetland,in Heilongjiang Province,China from April to October in 2008 and 2009.In the breeding season,the breeding pairs occupied an area and protected it throughout the reproduction,and both interspecific and intraspecific conflicts were observed.Territory activities became severe since early May,the peak of territory behaviors appeared at late May,and then declined gradually.The territorial activities level was higher than that in the nest building period than in the laying and incubation periods.The most adopted behavioral model was expelling,which was the least energy cost.The degree of territorial behavior tended to be descended since the development of breeding phase.The territory size differed from 1 333 m2 to above 5 000 m2.Wintering population was observed in Poyang Lake of Jiangxi Province.The coots gathered in the open water;however,there was no territory behavior both in the interspecies and intraspecies in wintering sites.The hypotheses why there was territory behaviors for coots both in the interspecies and intraspecies were also discussed. 展开更多

Global longitudinal strain (GLS) at rest on two-dimensional speckle tracking echocardiography (2D STE) was demonstrated to help detect coronary artery disease (CAD). However, the optimal cut-off point of GLS and its diagnostic power for detecting critical CAD in non-diabetes mellitus (DM) patients are unknown. In the present study, 211 patients with suspected CAD were prospectively included, with DM patients excluded. All patients underwent echocardiography and subsequently coronary angiography within 3 days. Left ventricular (LV) GLSs were quantified by 2D STE. Territorial peak systolic longitudinal strains (TLSs) were calculated based on the perfusion territories of the 3-epicardial coronary arteries in a 17-segment LV model. Critical CAD was defined as an area stenosis _〉70% in _〉1 epicardial coronary artery (_〉50% in left main coronary artery). Totally 145 patients were diagnosed as having critical CAD by coronary angiography. Significant differences were observed in all strain parameters between patients with and without critical CAD. The area under the receiver operating charcteristic (ROC) curve (AUC) for GLS in the detection of left main (LM) or threevessel CAD was 0.875 at a cut-off value of-19.05% with sensitivity of 78.1% and specificity of 72.7%, which increased to 0.926 after exclusion of apical segments (cut-off value -18.66%; sensitivity 84.4% and specificity 81.8%). The values of TLSs were significantly lower in regions supplied by stenotic arteries than in those by non-stenotic arteries. The AUC for the TLSs to identify critical stenosis of left circumflex (LCX) artery, left anterior descending (LAD) artery and right coronary artery (RCA), in order of diagnostic accuracy, was 0.818 for LCX, 0.764 for LAD and 0.723 for RCA, respectively. In conclusion, in non-DM patients with suspected CAD, GLS assessed by 2D STE is an excellent predictor for LM or three-vessel CAD with high diagnostic accuracy, and a higher cut-off point than reported before should be used. Excluding apical segments in the calculation of GLS can further improve the predictive accuracy of GLS. It is unsatisfactory for TLSs to be used to identify stenotic coronary arteries. 展开更多
