Research on the innovation path of corporate financial management based on improved Adaboost regression algorithm and analysis of management effectiveness

Abstract The first part of this paper investigates the implementation process of the Adaboost regression algorithm, initializes the training set weights to obtain the weak learner, and builds the final strong learner. Then, we explore the treatment of corporate financial management concept drift by assigning variance weights to financial data samples according to their temporal proximity to solve the problem of financial concept drift. Then, an optimized AdaBoost-SVM model is constructed to initialize the sample weights according to time and sample category, calculate the classification error, and build a weak classifier and a decision classifier based on the samples. Finally, the company's financial management costs, personnel, and model prediction accuracy were analyzed. The model predicts financial distress with a 78% accuracy, financial insolvency with a 93% accuracy, and financial normalcy with a 90% accuracy. This confirms the feasibility of this paper's methodology for corporate financial management.

Analysis and research on precise control mode of outdoor substation noise

As people pay more and more attention to the environmental noise problem of substations, it is an important environmental protection work to carry out noise control of over-subjected substation. According to the lack of strict scientific argumentation, poor engineering control effect and high project cost, the paper proposes an accurate control model for outdoor substation noise. Taking the actual substation as an example, with the development of the substation environmental noise analysis system software SENCS, through six steps of data collection, model verification, pre-treatment analysis, optimization of governance plan and analysis of management effects, it is proposed the model of precise control of outdoor substation, which can play an important guiding role in outdoor substation noise control and new substation planning and design..

A Brief Analysis on Management Effectiveness of College Enterprise Education

Based on the definition and characteristic analysis of management effectiveness, this paper analyzes the reason of the weakness in the management effectiveness of college enterprise education, and explores the following five aspects of improving management effectiveness in college enterprise education, including establishing reasonable enterprise education targets, setting up proper enterprise education curriculum, improving the teachers’ professional level, creating the effectiveness evaluation of innovation and enterprise education and feedback mechanism. This paper aims to make maximum use of enterprise education resources, to raise the level and quality of college enterprise education, and to promote college students’ entrepreneurship and employment finally.

Influencing factors and management effects analysis of pain for patients with upper limp fracture

Objective To select NRS to record and analyze influencing factors and management effects of pain for patients with upper limp fracture.Methods Totals of 164 patients with upper limp fracture had been chosen from February 2012 to February 2013, and all of them received PCIA combining with transfused flurbiprofen to relieve pain.We analyzed influencing factors of pain by Logistic regression analysis and recorded the maximum of pain score assessed by NRS at 24 h and 48 h after trauma and compared the pain score during break at 24 h, 48 h and 72 h after operation.Results The gender, age, length of fracture, position of fracture and fracture of AO type brought out different level of pain and those of pain had statistical difference （ P 〈0.05）.The gender （female）, age （beyond 60 years old）, position of fracture （proximal humerus fracture） and fracture of C type were severe risks to cause pain （P 〈0.05）.The pain scores of proximal humerus fracture, distal end of humerusfracture, radial fracture and ulnar fracture,which assessed by NRS, had statistical difference at 24 h and 48 h after fracture （F=81.756,84.288, respectively;P〈0.05）, while different position of fracture had high pain score at 24 h than 48 h （t=4.720,5.703,5.888, respectively;P〈0.05）.Under analgesia after operation at 24 h,48 h and 72 h, female patients had more effective pain control result than males （t=2.857,P〈0.05）.After 72hrs operation, there were ninety two cases satisfaction, fifty nine cases certain satisfaction and thirteen cases dissatisfaction for the result of pain control.Conclusions Because different gender, age, position of fracture and fracture type result in different level of pain, medical staff should provide reasonable pain management for fracture patient in order to enhance patient’ s satisfactory.

Multivariate relationships influencing crop yields during the transition to organic management

Crop yields are influenced by multiple, interacting factors, making it challenging to determine how specific management practices and crop rotations affect agroecosystem productivity. This is especially true in cropping systems experiments in which multiple management practices differ between experimental cropping system treatments. We conducted a cropping systems experiment in central Pennsylvania, USA, to analyze the effects of initial cover crop and tillage intensity on feed grain and forage crop productivity during the transition to organic production. We hypothesized that treatment effects of (1) tillage intensity (full or reduced); and (2) initial cover crops (annual rye (Secale cereale) or timothy/clover (Phleum pratense/Trifolium pratense)) on grain crop yield in a 3-year cover crop/soybean (Glycine max)/corn (Zea mays) rotation would be mediated by key agroecosystem function indicators (soil quality, weed pressure, and predatory arthropod activity). We used structural equation modeling (SEM) to attribute yield variation to treatment effects and abiotic factors as mediated by these ecosystem functions. We found that tillage intensity had both direct and indirect effects on corn yields. Full tillage had a direct, positive effect on corn yields, a negative effect on perennial weed density, and negative effect on a soil quality indicator (labile soil carbon). Full tillage also had an indirect effect on corn yields as mediated by perennial weed density. The initial cover crop influenced predatory arthropod activity-density and perennial weeds in year 2 (soybean phase), but had no effects in year 3 (corn phase). Abiotic and site factors influenced crop yields and other ecosystem functions in both rotation years. Our results highlight the utility of analytical approaches that consider the relationships among agroecosystem components. Through the analysis of management effects on multiple ecosystem functions, our results indicate that managing weed populations through tillage in organic systems can have the strongest effect on crop yields, although short-term profit gains may be at the expense of long-term loss in soil quality and beneficial insect conservation.
