Improved understanding of the spatial dynamics of invasive plant species is critical for effective land management and control of future invasion. The Yancheng National Nature Reserve (YNNR), an internationally important wetland, has the largest distribution of alien Spartina alterniflora in China. This alien plant was intentionally introduced for erosion prevention and dike protection in China. However, it became an aggressive competitor with native salt marsh plants in the coastal regions in China. High resolution imagery, SPOT-5, was used to map plant communities including invasive species in the south core zone of YNNR with the natural ecosystem of salt marshes in 2003, 2005 and 2008. The fuzzy set assessment method significantly improved the classification accuracies over the conventional error matrix, i.e., from 73.8%, 73.5% and 81.4% to 91.5%, 91.6% and 93.4% in 2003, 2005 and 2008, respectively. It shows a great potential for mapping invasive plant species. Phragmites australis and S. alterniflora were the most accurately mapped classes, and sparse and dense Suaeda glauca were the least accurately mapped. From 2003 to 2008, S. alterniflora increased 28.8% from 1664.1 to 2142.6 ha in area size, and more than 2.5 times from 742 to 2608 patches. The highest increase in patch number occurred within the interval between 2001 and 3000 m from the eastern baseline. This increase was dominated by small patches with area less than 200 m<sup>2</sup>. During the study period, the mean spread width was 405 ± 80.7 m in the original large patch of area over 200 ha. The eastward/seaward spread was distinctively larger than the westward/landward. The results enhance the understanding of alien plant’s invasion patterns and help improve conservation efforts. 展开更多

Background: Request for preoperative laboratory investigations is usually done by surgeons. On some occasions, the patient may come with laboratory investigations that have been requested by the primary physician. This occurs in situations where the primary physician saw the patient first and referred to the surgeon. There is usually no indications based on history or physical examination before these laboratory request is done but rather on speculations that the “anaesthetist may require them”. This is done in order to avoid cancellation or delay of cases. The aim of this study was to find out how tests ordered in Komfo Anokye Teaching Hospital (K.A.T.H.) by the surgeons affected the decisions of the anaesthetists in the perioperative management of the patients. Methodology: This was a prospective, cross sectional study of patients undergoing elective surgery at K.A.T.H from 1st to 31st March 2014. A quantitative technique was used to effectively quantify laboratory results that were contained in a patient’s folder before an elective surgical procedure. A close and open-ended questionnaire was developed and answered by reviewing patient’s folders during the pre-anesthesia assessment. Data were analyzed using Statistical Package of Social Sciences (SSPS) version 22. Results: The average age of patients studied was 50 years. Abnormal test results did not influence the anaesthetic management in 70.5% of cases but led to either delay or cancelation of cases or requirement for transfusion of blood or blood products in 29.5% of cases. Conclusion: Preoperative laboratory tests ordered by Surgeons in KomfoAnokye Teaching Hospital do not significantly influence the anaesthetic managements of patients. 展开更多

Urban parks are an important part of urban ecosystems and also provide recreational services for urban residents.However,it is still unclear how the recreational attractiveness of urban parks can be evaluated.In this study,12 typical parks in Changchun,China were selected for evaluation of their recreational attractiveness.We built a recreational attractiveness evaluation system based on the analytical hierarchy process(AHP)to produce a composite evaluation index.This method included:1)the landscape quality of the parks;2)the recreational facilities;3)the conditions of the area;and 4)the accessibility of the parks.Our results showed that Nanhu Park,Children’s Park,Shengli Park,and Jingyuetan Forest Park had high recreational attractiveness,whereas Linyuan Park had the lowest attractiveness among the 12 parks.These results agreed with the information obtained from a field survey of the actual recreational and revisit rates,which showed that the evaluation index is reliable.Correlation analysis showed that the landscape quality and recreational facilities of parks had a direct effect on their recreational attractiveness.A negative correlation was found between the accessibility of a park and its recreational attractiveness.We conclude that if the scenery and facilities are not as good as a visitor expects,then they may choose to visit a different park,even if it takes a longer time to reach. 展开更多

This paper will review three broad types of political implications of emergency management, since historically emergency management was considered only a function of law enforcement and fire departments, with the support in the event of a major catastrophe from public health and civil defense organizations. The issue is not whether governments will be required to respond to emergencies but rather when and how frequently. The time to think about emergencies is before they happen. Despite some significant weakness in the overall approach, political implications offer many benefits and provide various options for CDCs (community development corporations) to get involved in disaster recovery and emergency management. Based upon a generally positive evaluation, the paper concludes that emergency management must become a central activity, whether at the federal, state, or local or as an intergovernmental activity. Hopefully for the future the government does not have to wait for a disaster to strike for one to put a policy into place, since they have had several to occur over decades. The government should be ready to take on any disaster if it occurs with the following policies and procedures that are in place. 展开更多

The reduction of wasteful variation within the supp ly chain is naturally suited to high and stable volumes, as epitomised in the lean practices of the automotive industry. However, with the growth of innovative pr oducts, typically characterised by lower volumes and uncertain demand, it is als o important to develop strategies to effectively manage the externally imposed v ariation resulting from volatile market demand. Such strategies often come under the banner of quick response or agile supply. System variation is the common denominator, for whereas lean strategies emphasis e the need for stability and the reduction of wasteful supply chain variation, a gile emphasises the need to respond to externally imposed demand variation. Simi larly, lean supply is closely associated with level scheduling and investing in inventory to decouple demand variation from the supply chain, whereas, agile sup ply is associated with investing in responsive capacity as inventory requirement s cannot be effectively predicted. This distinction between lean and agile supply, highlights a trade-off between investing in responsive capacity and decoupling inventory, which is closely related to the conflicting manufacturing tasks of fast response and low cost. The implications of this conflict have been more widely felt in recent years, as companies have opted to outsource manufacture to low cost overseas suppliers. T he rationale is to reduce manufacturing costs, but the trade-off is a dramatic loss of responsive capacity with higher dependency on decoupling inventory. As with lean and agile supply, the trade-off implications of such choices need to be acknowledged, conceptually understood and then separate out or otherwise r esolved. This paper introduces the business need before exploring the significance of var iation and the concept of managing variation in a delivery system using responsi ve capacity and decoupling inventory. These concepts will then be used to unpack the lean and agile paradigms before applying the thinking to a more detailed in dustrial case concerning offshore supply decisions. The paper concludes with som e reflections. 展开更多

Endoscopy plays a fundamental role in the diagnosis, management, and treatment of inflammatory bowel dis-ease(IBD). Colonoscopy, flexible sigmoidoscopy, and esophagogastroduodenoscopy have long been used in the care of patients with IBD. As endoscopic technologies have progressed, tools such as endoscopic ultrasound, capsule endoscopy, and balloon-assisted enteroscopy have expanded the role of endoscopy in IBD. Furthermore, chromoendoscopy has enhanced our ability to detect dys-plasia in IBD. In this review article, we will focus on the roles, indications, and limitations of these tools in IBD. We will also discuss the most commonly used endoscopic scoring systems, as well as special considerations in post-surgical patients. Lastly, we will discuss the role of endoscopy in the diagnosis and management of fistulae and strictures. 展开更多

The etiology of these symptoms include skin tags, ulcers, fissures, abscesses, fistulas or stenoses. Fistula is the most common perianal manifestation. Multiple treatment options exist although very few are evidence-based. The phases of treatment include: drainage of infection, assessment of Crohn's disease status and fistula tracts, medical therapy, and selective operative management. The impact of biological therapy on perianal Crohn's disease is uncertain given that outcomes are conflicting. Operative treatment to eradicate the fistula tract can be attempted once infection has resolved and Crohn's disease activity is controlled. The operative approach should be tailored according to the anatomy of the fistula tract. Definitive treatment is challenging with medical and operative treatment rarely leading to true healing with frequent complications and recurrence. Treatment success must be weighed against the risk of complications, specially anal sphincter injury. A full understanding of the etiology and all potential therapeutic options is critical for success. Multidisciplinary management of fistulizing perianal Crohn's disease is crucial toimprove outcomes. 展开更多

Barrett's esophagus is a condition resulting from chronic gastro-esophageal reflux disease with a documented risk of esophageal adenocarcinoma. Current strategies for improved survival in patients with Barrett's adenocarcinoma focus on detection of dysplasia. This can be obtained by screening programs in high-risk cohorts of patients and/or endoscopic biopsy surveillance of patients with known Barrett's esophagus (BE). Several therapies have been developed in attempts to reverse BE and reduce cancer risk. Aggressive medical management of acid reflux, lifestyle modifications, antireflux surgery, and endoscopic treatments have been recommended for many patients with BE. Whether these interventions are cost-effective or reduce mortality from esophageal cancer remains controversial. Current treatment requires combinations of endoscopic mucosal resection techniques to eliminate visible lesions followed by ablation of residual metaplastic tissue. Esophagectomy is currently indicated in multifocal high-grade neoplasia or mucosal Barrett's carcinoma which cannot be managed by endoscopic approach. 展开更多

The study aimed to retrospectively evaluate surgical treatment outcomes after delayed parotid gland and duct injuries. Nine patients subjected to parotid gland and duct injuries with l- to 3-month treatment delay were retrospectively evaluated with special reference of etiology, past medical history, and injury location. Conservative treatment, microsurgical anastomosis, and diversion of salivary flow or ligation were chosen for delayed parotid gland and duct injuries concerning to their site of injury, time of repair and procedures. Assistant treatment as pressure dressing was adopted thereafter. All patients experienced an uneventful recovery at the time of finalizing the study. Two patients received Stensen's duct ligation, 5 received microsurgical anastomosis and 2 accepted salivary flow diversion for 5 patients with sialoceles and 4 patients with fistulas, and no re-occurrence was found. Facial paralysis occurred after surgery in 4 patients, and 3 of them recovered after the nerve nutrition treatment. Our study suggested that appropriate surgical treatment is efficient for the re-establishment of the tissue function and facial aesthetic for delayed injury of the parotid and its duct. 展开更多

Subtypes of dementia include Alzheimer's, frontotemporal, Parkinson's, Lewy body disease, and vascular type. Dementia is associated with a variety of neuropsychiatric symptoms that may include agitation, psychosis, depression, and apathy. These symptoms can lead to dangerousness to self or others and are the main source for caregiver burnout. Treatment of these symptoms consists of nonpharmacological and pharmacological interventions. However, there are no Food and Drug Administration-approved medications for the treatment of behavioral and psychological symptoms of dementia. Pharmacological interventions are used off-label. This article reviews the current evidence supporting or negating the use of psychotropic medications along with safety concerns, monitoring, regulations, and recommendations. 展开更多

The Shicaogou granite has been identified as a magnesian (Fe-number=0.71-0.76), calcic to calc-alkalic (MALI=3.84-5.76) and peraluminous (ASI=1.06-1.13) granite of the syn-collisional S-type, with high SiO2(>71%), A12O3 (>13%) and Na2O+K2O (6.28%-7.33%, equal for NaO2 and K2O). Trace element and REE analyses show that the granite is rich in LILE such as of Rb, Sr, Ba and Th, and poor in HFSE like Yb, Y, Zr and Hf. Its Rb/Sr ratio is greater than 1; the contents of Nb and Ta, and the ratio of Nb/Ta as well as the REE geochemical features (e.g. REE abundance, visible fractionation of LREE and HREE and medium to pronounced negative Eu anomalies) are all similar to those of crust-origin, continent-continent syn-collisional granite. Moreover, the granite exhibits almost the same pattern as that of the typical continent-continent syn-collisional granite on the spider diagram and all samples fall within the syn-collisional granite field.The cathodoluminescence (CL) investigations have revealed that the zircon from the Shicaogou granite represents a typical magmatic product characterized by its colorless, transparent and euhedral crystals, and distinct zoning of oscillatory bands. Residual cores of irregular zircon can be found in a few enhedral grains. Trace element studies of the zircon grains, with high contents of P, Y, Hf, Th, U and REE and high ratios of Th/U, obviously positive Ce anomalies and HREE enrichment compared to LREE, also result in the same conclusion.The LA-ICP-MS U-Pb isotopic data from 24 spots of 21 zircon grains demonstrate that 20 spots in the oscillatory zone yield an average weighted 206Pb/238U age of 925±11 Ma, indicating that the Shicaogou granite was formed in the Neoproterozoic. Combined with other Neoproterozoic syn-collisional granites found in the study area, the present geochronological determination can further reveal that collision-amalgamation events could have occurred among some continental blocks in the Qinling orogenic belt during the Neoproterozoic. This in turn provides an accurate chronological constraint on the Neoproterozoic break-up and convergence in the belt. 展开更多
