Pick the Right Tactics When Online Sales Go Live: An Empirical Analysis of Livestreaming for Amazon Sellers

Using livestreaming to boost sales has become an essential strategy to achieve deeper interactions with customers for many large e-commerce platforms worldwide. Existing livestreaming literature has looked at multiple Chinese e-commerce platforms but not enough attention has been paid to the U.S. market. This study investigates consumer behaviors and the promotion efficacy in the Livestream setting on Amazon Live. We analyze the time patterns of customer engagement and explain why sellers should use different promotion strategies for weekdays and for weekend streamers. Besides, we present evidence that the average video display time per product is crucial for the livestream promotion efficacy and suggest optimal time-exposure intervals as a benchmark for sellers to align with

中国财政政策调整的宏观经济效应——基于消费者异质性的新凯恩斯模型

This paper construct the NK model with Cosummer’s Heterogeneity included three sectors, in which government is divided into three type of fiscal sector, social security department and central bank. The tax shocks, social security fees rate shock and fiscal expenditure shock are incorporated with the NK model to explord the contribution and the dynamic effect of the fiscal policy shocks on macroeconomic volatility. The results show that (1) the shocks of good taxation contribute most in real economy than the shocks of other fiscal policy, and the size of contribution on macroeconomic volatility is 65%; (2) reducing of the tax rates, social security fees rate and fiscal spending stimulate economic growth, and it is more important that cutting the tax rate of labour income and lowering social security fees rate are better measures; (3) cutting tax rates and lowering of social security fees rate improve the fiscal sustainability; (4)the inflation is a joint monetary-fiscal phenomenon. On this basis, this paper propose that government should adopt active tax and fee policies---cutting labour income taxation rate and lower social security fees rate, to spur stable economic growth, simultaneously raise benchmark interest rate to prevent inflation

One method of maximizing efficiency is automation, the technique of making a system operate automatically. Through automation, manual processes can be streamlined to eliminate waste. This project outlines the automation of the Individual Service Agreement (ISA) process at One Sky Community Services. The three stages of this process, Creation, Review, and Approval, were prototyped and implemented into a digital management system, Microsoft SharePoint Online, using Agile methodologies

Interpreting Religious Heritage

Churches in the city of London are an important part of the religious heritage of the UK, but they lag behind other popular heritage sites in terms of promotion and accessibility. The goal of this project was to identify ways to promote the religious heritage of the UK through improved access to and better curation of the art, artifacts, and architecture of churches. We conducted interviews with stakeholders in heritage and access, distributed a survey to members of a religious heritage organization, and visited numerous churches and other heritage sites in London and southeast England. To conclude, we recommend how church administrators and clergy, the Friends of the City Churches, and other religious heritage organizations can improve access to and promotion of religious heritage

PanoVOS: Bridging Non-panoramic and Panoramic Views with Transformer for Video Segmentation

Panoramic videos contain richer spatial information and have attracted tremendous amounts of attention due to their exceptional experience in some fields such as autonomous driving and virtual reality. However, existing datasets for video segmentation only focus on conventional planar images. To address the challenge, in this paper, we present a panoramic video dataset, PanoVOS. The dataset provides 150 videos with high video resolutions and diverse motions. To quantify the domain gap between 2D planar videos and panoramic videos, we evaluate 15 off-the-shelf video object segmentation (VOS) models on PanoVOS. Through error analysis, we found that all of them fail to tackle pixel-level content discontinues of panoramic videos. Thus, we present a Panoramic Space Consistency Transformer (PSCFormer), which can effectively utilize the semantic boundary information of the previous frame for pixel-level matching with the current frame. Extensive experiments demonstrate that compared with the previous SOTA models, our PSCFormer network exhibits a great advantage in terms of segmentation results under the panoramic setting. Our dataset poses new challenges in panoramic VOS and we hope that our PanoVOS can advance the development of panoramic segmentation/tracking

Synthesis, crystal structure and bioactivity of phenazine-1-carboxylic acylhydrazone derivatives

A phenazine-1-carboxylic acid intermediate was synthesized from the reaction of aniline and 2-bromo-3-nitro-benzoic acid. It was then esterified and reacted with hydrazine hydrate to afford phenazine-1-carboxylic hydrazine. Finally, 10 new hydrazone compounds 3a–3j were obtained by the condensation reaction of phenazine-1-carboxylic acid hydrazide and the respective aldehyde-containing compound. The structures were characterized by 1H and 13C NMR spectroscopy, MS and single crystal X-ray diffraction. The antitumor activity of the target compounds in vitro (HeLa and A549) was determined by thiazolyl blue tetrazolium bromide. The results showed that compound (E)-N′-(2-hydroxy-4-(2-(piperidine-1-yl) ethoxy) benzyl) phenazine-1-carbonyl hydrazide 3d exhibited good cytotoxic activity

1H NMR-Based Metabolomics Reveals Refined-Huang-Lian-Jie-Du-Decoction (BBG) as a Potential Ischemic Stroke Treatment Drug With Efficacy and a Favorable Therapeutic Window

Huang-Lian-Jie-Du-Decoction (HLJDD) is a traditional Chinese medicine (TCM) used to treat ischemic stroke. However, the complexity of its chemical composition makes quality control difficult. Berberine, baicalin, and geniposide are the three main ingredients in HLJDD. Here, a formula of BBG comprised of berberine, baicalin, and geniposide, known as Refined-Huang-Lian-Jie-Du-Decoction, was investigated for its efficacy, therapeutic window, and mechanisms of action. BBG was assessed on two major types of ischemic stroke, cerebral ischemia-reperfusion (I/R) injury, and continuous ischemia injury, respectively. BBG showed efficacy comparable to HLJDD in the treatment of cerebral I/R injury within 5 h after injury initiation but did poorly in treating continuous ischemia injury. BBG exhibited neuroprotective effects on cerebral I/R injury by regaining the balance in energy metabolism, oxidative stress, amino acid metabolism, inflammation, and nucleic acid metabolism. These results suggested that BBG could be a good alternative to HLJDD, with high efficacy and a long therapeutic window, which shows great potential for drug development to treat stroke

Survival after radiofrequency ablation and/or chemotherapy for lung cancer and pulmonary metastases: a systematic review and meta-analysis

BackgroundRadiofrequency ablation (RFA) and chemotherapy are used to treat lung cancer or pulmonary metastases, but no direct comparison of overall survival (OS) has been published. The present study aimed to assess the OS of RFA and/or chemotherapy in patients with lung cancer or pulmonary metastases who were not candidates for surgical resection.MethodsTo identify relevant studies, the following databases were electronically searched from their inception to 31 March 2023: PubMed, Embase, Web of Science, Cochrane Library, Scopus, Ovid, ScienceDirect, SinoMed, China National Knowledge Infrastructure Database, Chongqing VIP Chinese Science and Technology Periodical Database, Wanfang Database, LILACS, ClinicalTrials.gov, and Chictr.org. Manual retrieval was also conducted. We used published hazard ratios (HRs) if available or estimates from other survival data.ResultsA total of 1,387 participants from 14 trials were included in the final analysis. Patients treated with RFA combined with chemotherapy significantly improved OS compared with those treated with chemotherapy alone [HR 0.50, 95% confidence interval (CI) 0.41–0.61; p < 0.00001], with an absolute difference at 12 months of 29.6% (95% CI 23.7–35.5), at 24 months of 19.2% (95% CI 10.1–28.2), and at 36 months of 22.9% (95% CI 12.0–33.7). No statistically significant difference was observed in the subgroups of case type, cancer type, chemotherapy drugs, and tumor size. The HR for OS with RFA plus chemotherapy vs. RFA alone was 0.53 (95% CI 0.41–0.70; p < 0.00001), corresponding to a 27.1% (95% CI 18.3–35.8), 31.0% (95% CI 19.9–41.9), and 24.9% (95% CI 15.0–34.7) absolute difference in survival at 12 months, 24 months, and 36 months, respectively. Subgroup analysis by geographic region and TNM stage showed that RFA combined with chemotherapy still significantly improved OS compared to RFA. The HR of RFA vs. chemotherapy was 0.98 (95% CI 0.60–1.60; p = 0.94), with an absolute difference at 12 months of 1.4% (95% CI -19.2 to 22.1), at 24 months of 7.8% (95% CI -11.3 to 26.8), and at 36 months of 0.3% (95% CI -13.2 to 13.8). The overall indirect comparison of OS for RFA vs. chemotherapy was 0.95 (95% CI 0.72–1.26; p = 0.74). Data on progression-free survival were not sufficiently reported.ConclusionRFA combined with chemotherapy might be a better treatment option for patients with lung cancer or pulmonary metastases than chemotherapy alone or RFA alone. The comparison between RFA and/or chemotherapy remains to be specifically tested.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=335032, identifier CRD42022335032
