Food is one of the biggest industries in developed and underdeveloped countries. Supply chain sustainability is essential in established and emerging economies because of the rising acceptance of cost-based outsourcing and the growing technological, social, and environmental concerns. The food business faces serious sustainability and growth challenges in developing countries. A comprehensive analysis of the critical success factors (CSFs) influencing the performance outcome and the sustainable supply chain management (SSCM) process. A theoretical framework is established to explain how they are used to examine the organizational aspect of the food supply chain life cycle analysis. This study examined the CSFs and revealed the relationships between them using a methodology that included a review of literature, interpretative structural modeling (ISM), and cross-impact matrix multiplication applied in classification (MICMAC) tool analysis of soil liquefaction factors. The findings of this research demonstrate that the quality and safety of food are important factors and have a direct effect on other factors. To make sustainable food supply chain management more adequate, legislators, managers, and experts need to pay attention to this factor. In this work. It also shows that companies aiming to create a sustainable business model must make sustainability a fundamental tenet of their organization. Practitioners and managers may devise effective long-term plans for establishing a sustainable food supply chain utilizing the recommended methodology. 展开更多

Manufacturing industries are facing challenges in the implementation of agile manufacturing in their products and processes. Agility is widely accepted as a new competitive concept in the manufacturing sector in fulfilling varying customer demand. Thus, evaluation of agile manufacturing in industries has become a necessity. The success of an organisation depends on its ability to manage finding the critical success factors and give them special and continued attention in order to bring about high performance. This paper proposes a set of critical success factors (CSFs) for evaluating agile manufacturing considered appropriate for the manufacturing sector. The analytical hierarchy process (AHP) method is applied for prioritizing the success factors, by summarizing the opinions of experts. It is believed that the proposed CSFs enable and assist manufacturing industries to achieve a higher performance in agile manufacturing so as to increase competitiveness. 展开更多

This study suggests a theoretical component to the thus far proposed explanations of what makes a startup incubator successful in enabling entrepreneurial activity. Departing from a traditional focus on industry- and nation-wide resources, we develop a framework of the critical success factors for a startup incubator and a scoring mechanism to evaluate the success of existing startup incubators using these factors. We score a selection of American and European incubators using the developed scoring mechanism and comparatively benchmark the European incubators against the American ones to identify areas for improvement. Our findings suggest that European incubators, while relatively strong overall, can look to and learn from their American counterparts in certain areas. Importantly, these improvement areas are not specific to characteristics of any individual European incubator, but to European incubators overall. Finally, we aim to expand this study to other entrepreneurship hubs worldwide and we outline a plan of action to enable this expansion. 展开更多

In the last years, most of the leader companies have advantages of their CRM (customer relationship management) systems in order to improve their market share. These companies implement CRM systems to get loyal customer portfolio and maintain the sustainability of it. While they are building CRM strategies, they try to catch business excellence results like valuable marketing opportunities, improve customer value and customer satisfaction. CRM gained prominence as a marketing sub-discipline in the 1990s, fueled by publications like The One to One Future and The Loyalty Effect. Some studies were especially powerful in highlighting the gap between the cost of acquiring customers and retaining them. The quest for competitive advantage and profitability triggered a rush to implement CRM programs in enterprises both large and small in all comers of the globe. Different kinds of studies show that there are some key components which play a critical role in gaining success for companies which use CRM applications. At this situation, these key components are named as critical success factors. Purpose of this study is to find out that how these critical success factors affect results which show company performance. On this direction, critical success factors are defined as independent variable and company performance is defined as dependent variable. A supportive model is suggested. In order to verify proposed model, hypotheses are developed and a survey is applied in automotive sales agents in Turkey. The study is completed with survey results. 展开更多

Objective This study aims to assess the status of successful aging (SA) in longevity areas in China and explore multiple factors associated with SA among the young-old and oldest-old. Methods A total of 2296 elderly people aged 65 and older were interviewed in the longevity areas sub-sample of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2012. Baseline assessments included a researcher-administered questionnaire, physical examination, and laboratory testing. A logistic regression model was used to identify factors associated with SA. Results The prevalence of SA was 38.81% in the CLHLS in 2012. There were significant differences between ages groups, with SA compromising 56.85% among _〉65 years group and 20.31% among 〉100 years group (X2trend=126.73, P〈O.01). The prevalence of SA among females was 33.59%, which was significantly lower than that among males (45.58%) (X2gender=33.65, P〈0.05). In the regression analysis, having anemia ~OR=0.744, 95% CI: 0.609-0.910), poor lifestyle (OR=0.697, 95% CI: 0.568-0.854), poor sleep quality (OR=0.558, 95% CI: 0.456-0.682), and central obesity (OR=0.684, 95% CI: 0.556-0.841) were the main factors associated with SA. The promoting SA rate decreased as age increased, and the group of 65-79 years had higher odds than the other age group. Conclusion Preventing central obesity, improving sleep quality and promoting healthy lifestyle may contribute to achieve SA among the elderly. 展开更多

To understand the responses of a freshwater ecosystem to the impoundment of the Three Gorges Reservoir (TGR), phytoplankton was monitored in the tributaries of the TGR area. From August 2010 to July 2011, algal species composition, abundance, chlorophyll a and other environmental parameters were investigated in the Gaolan River, which is a tributary of Xiangxi River. Thirty-one algal genera from seven phyla were identified. Results show that the lowest concentrations of total phosphorus (TP) and total nitrogen (TN) were 0.06 mg/L and 1.08 rag/L, respectively. The values of TP and TN exceeded the threshold concentration of the eutrophic state suggested for freshwater bodies. In the Gaolan River, the succession of phytoplankton showed clear seasonal characteristics. Different dominant species were observed among seasons under the control of environment factors. In spring and summer, the dominant species were Nitzschia sp. and Aphanizomenon flos-aquae (L.) Ralfs, the limiting nutrient was NO3^--N, and the key environmental factor for phytoplankton population succession was water temperature (WT). In autumn and winter, the dominant species were A.flos-aquae and Chlorella sp., the limiting nutrient was pO3--P, and the key environmental factors were transparency and WT. This study illustrates the influence of physical and chemical factors on phytoplankton seasonal succession in a tributary of TGR since the downstream regions of Xiangxi River and Gaolan River became reservoirs after impoundment of the Three Gorges Dam. We suggest that this activity has significantly affected water quality in the dam area. 展开更多

Reservoirs are an important water source in many densely populated areas in southwest China.Phytoplankton play an essential role in maintaining the structure and function of reservoir ecosystems.Understanding the succession in phytoplankton communities and the factors driving it are essential for eff ective water quality management in drinking water reservoirs.In this study,water samples were collected monthly at the surface layers from March 2016 to December 2019 in Hongfeng Reservoir,southwest China.The relationship between functional group succession was analyzed based on nonmetric multidimensional scaling analysis(NMDS),redundancy analysis(RDA),succession rate,and other analysis methods.The results showed distinct shifts in the community structure of phytoplankton functional groups within study period.The Cyclotella sp.was dominant in 2016 and 2017,and Pseudanabaena limnetica was the dominant group in 2018 and 2019.It appears that the phytoplankton composition and biomass are closely related to the water temperature and nutrient status in this reservoir.The results clearly showed that the permanganate index(COD_(Mn))was the key factor of dramatic phytoplankton functional group succession,and the change in succession rates was closely caused by total nitrogen concentration(TN).Therefore,the succession pattern and key factors of Hongfeng Reservoir revealed in this study were important guidance for the management of drinking water reservoirs in southwest China.A reasonable limit on exogenous nutrient input should be a priority,especially in high water temperature period. 展开更多

The purpose of this study was to define factors that have a significant impact on the stone-free rate after ESWL. Methods: A total of 417 patients harboring renal or ureteral stones underwent extracorporeal shock wave lithotripsy (ESWL) between October 2008 and July 2012. Eighty five patients were lost on follow up. The remaining (n = 332). All patients were >18 yr of age. Siemens and SLX-F2 electromagnetic machines were used to impart shock waves. Patients were stratified according to localization (pelvic, calyceal, or ureteral stones) and stone size (up to 10 mm, 10 - 20 mm, and >20 mm). Result: The overall success rate was 251/332 (75.6%) achieve stone free status. Repeated ESWL sessions were needed in 258 (61.9%). Of eleven variables were studied including age, sex, side, location (pelvic, calyx, ureter), ureteric stent, previous renal surgery, stone size, number of shock waves, opacity of stone, renal system state, and type of lithotripter, three variables were significantly affect the success rate namely stone size, number of shock waves and location of stone. Conclusions: ESWL remains one of the most commonly utilized treatments for patients with upper urinary tract calculi;Stone diameter, location, and number of shock waves, are the most important predictors determining stone clearance after ESWL of renal and ureteric calculi. To optimize treatment outcomes with ESWL the presence of treating urologist is essential to optimize the final result. 展开更多

The independent risk factors to predict mortality of critical severe acute respiratory syndrome (SARS) were investigated. One hundred and two patients diagnosed with critical SARS were admitted to hospitals of Shanxi Province, from March 7, 2003 to June 4, 2003. The patients were prospectively studied after admission to access their short term outcomes and the risk factors associated with adverse outcomes, defined as death. All the demographic and clinical characteristics were studied and univariate and multivariate Logistic regression were employed to access the risk factors. The results showed that of the 102 cases, 23 patients died, with a crude mortality rate of 22.5 %. Multivariate Logistic regression revealed that age above 50 [odds ratio (OR) 1.10, 95 % confidence internal (CI) 1.03 to 1.16, P=0.004], lymphopenia at early stage (OR 14.62, 95 % CI 1.78 to 11.97, P=0.01) were independently associated with mortality. On the other side, psychotherapy (OR 0.01, 95 % CI 0.00 to 0.06, P<0.001) was independently associated with aliveness. It was concluded that critical SARS is a new disease entity that carries significant mortality and morbidity. Specific clinical and laboratory parameters predicting unfavorable and favorable outcomes have been identified. 展开更多

In order to investigate the influence of season changes of environmental factors in closed shrimp ponds on the community structure of planktonic microalgae,this paper conducted isolated tests to the temperature,pH,total nitrogen( TN),total phosphorus( TP) and chlorophyll a in the shrimp culture ponds,analyzed the planktonic microalgae community structure and changes of dominant species in water over the same period,with the aim to explain the responses of microalgae community to changes of environmental factors in the pond without foreign water sources.The results showed that pond water temperature and TP content gradually increased from April to the end of September and then declined in October; water pH first decreased and then increased; TN and chlorophyll a first increased and then decreased.The dominant species in the pond were Cyclotella sp.,Navicula sp.,Oocystis borgei and S.quadricauda in the early stage( Apirl-May),Chlamydomonas sp.,Chlorella sp.,S.quadricauda,Golenkinia radiata and Pseudanabeanain in medium stage( June-July),Microcystis,Pseudanabeana,Chlorella sp.And S.quadricaudain in the mid-late stage( August-September),Microcystis,Pseudanabeana,Oscillatoria sp.and Chlorella sp.in the late stage( October-December),and Chlorella sp.,Golenkinia radiate,S.quadricauda in the last stage.Diatoms and green algae were the dominant species in the early stage when the water had low temperature,low N and P nutrition but high N/P and a certain salinity.With the increase of temperature,water desalination and accumulation of N and P nutrition,algae became the dominant species.Cyanobacteria became the strong dominant stages in the mid-late stage when the water had high temperature in the state of eutrophication,and there were also some green algae which were fond of high temperature and had resistant to pollution.In the late stage,cyanobacteria were the absolute dominant stage,but with the decrease of water temperature in the last stage,green algae became the dominant species,and planktonic microalgae biomass in the pool decreased. 展开更多
