Effective Strategies For Small Startups To Attract Venture Capital

In essence, for small startups, securing VC is a major breakthrough for growing and scaling up their business. The paper now zeroes in on the tactics that small startups can employ to capture, to a larger extent, the potential attention of VCs. The most critical strategies in order to engage VCs will be what this discussion will be based on as we turn into a collection of previous literature, case studies, and expert insights. Forge a Convincing Business Model: One solid business model is what lies at the core of how to attract VC investment. How a startup can sketch out its value proposition, revenue streams, and path to scaling. This business model does not only bring out the potential for high returns that the startup might have; it also aligns with the risk appetite of these venture capitalists. Network Building: Networking forms one of the core functions of the entire venture capital business. This paper looks into just how a network of one's own can be built and leveraged via industrial connections, along with mentors and advisors. Proper networking will result in more visibility and credibility, thus increasing the opportunity for start-ups to reach out to potential investors. Demonstrating Market Potential: For venture capitalists, the ability to demonstrate a clear market potential is very much desirable from startups. We will see how startups can present information on market size, customer segments, and competitive landscape to secure an investment interest. Making a Strong Pitch: Preparing a convincing pitch is a sure way of attracting the interest of VCs. We will look at the main components of the pitch: elevator pitch, articulating the problem and solution, definition of the market opportunity, articulation of the solution itself, business model, traction, team, and financial projections. Preparing a sound pitch can dramatically increase the chance of receiving venture capital. Apart from these, the paper also makes the target to address the critical pitfalls which startup companies often face in the form of indistinct ideas, over-promise on market size, and unrealistic projections for financials. It must help the startups, through practical recommendations and insights, reach an optimization of approaches toward venture capital and hence secure the necessary funding portions of growth and success

The Model of Stock Pricing Banking Sector on the Indonesia Stock Exchange during the Government of Susilo Bambang Yudhoyono and Joko Widodo

Differences in macroeconomic conditions between the SBY and JKW government periods can significantly impact stock prices within the banking sector, especially when the economy experiences fluctuations, leading to increased stock price volatility. This research aims to assess the influence of various macroeconomic factors, including the Global index, macroeconomics, world oil prices, China index, Arab index, competitive resources, and inflation, on banking sector returns from October 2004 to October 2014. The analysis utilizes the arbitrage pricing theory, difference test, and mean absolute deviation. The study divides the analysis into high-return and low-return groups for each government period. Findings indicate that macroeconomic factors exert a simultaneous influence on return groups during both SBY and Jokowi's administrations. However, for JKW high returns, these factors do not significantly impact them. Specifically, the Global Index, China Index, Arab Index, Resource Competitiveness, and Inflation show a positive correlation with both high and low returns during SBY term. Conversely, during JKW tenure, only the Global Index and China Index exhibit positive effects on high and low returns. The difference test reveals disparities in the Arab index for high and low returns of SBY, while only the Global index displays differences for JKW. The variations in high returns between SBY and Jokowi stem from discrepancies in the Global and Arab indices, while no distinctions exist in low returns between the two administrations. Additionally, the mean absolute return values for high returns during JKW era demonstrate the smallest accuracy, indicating potential limitations in the predictive power of the model during this period.

주식을 이용한 사기 피해 방지방안에 관한 연구

Fraud crime using stocks (hereinafter referred to as fraud crime) refers to defrauding investments by supplying listed stocks, unlisted stocks, and overseas futures at lower prices than the actual transaction price using virtual securities companies and inducing investment by guaranteeing high returns. Since this crime is committed using fake phones and fake bank accounts in cyberspace called communication media, it is difficult to identify criminals, making it difficult to arrest them. Victims of fraud suffer from mental pain such as depression, anxiety, regret, and despair due to financial loss. Therefore, related agencies will not be able to stop crimes unless legal, institutional, and policy countermeasures are sought to prevent them. To prevent this, it is necessary to seek proactive and follow-up measures. First, the preliminary precautionary measure is ① by enacting a law on criminal law alarms to prevent damage by informing investigative agencies or financial institutions of the criminal law to the entire population. ② Even if an investor remits the investment, the investment should not be remitted for a certain period of time through the remittance transfer delay system, so that the investment should not be remitted to the criminal's account when the investor is judged to be fraudulent. ③ Financial institutions notify the investigative agency when a large amount of deposit and withdrawal accounts occur for a certain period of time, and when a damage report is received for the account, the investigative agency must immediately obtain a seizure and search warrant and confiscate it to prevent further damage. ④ Employees of financial companies should be able to impose the obligation to notify them through the revision of related laws that they can be punished if they are used for identification procedures and crimes when opening mobile phones and bankbooks. Next, the follow-up measures are ① The National Assembly should strengthen criminal punishment through the revision of the criminal law so that fraudulent crimes are not considered “remaining business,” so that potential criminals do not only prevent crime but also lead to crime. ② When a crime damage report is received, the investigative agency should obtain a real-time communication warrant so that the criminal can be located and arrested. ③ The National Assembly should unify the request for a search warrant from the police to the court so that investigative agencies can obtain warrants early and confiscate mobile phones and bank accounts. ④ The Ministry of Justice should establish a law enforcement agency dedicated to fraud so that it can arrest criminals and prevent crimes by securing expertise and giving investigative power superior to criminal methods. ⑤ The National Assembly should enact a law on suspension of withdrawal to prevent withdrawal when a financial institution requests the suspension of withdrawal, knowing that the investor is a fraud. These countermeasures will be a great driving force in preventing fraudulent crimes.

A novel mass integration cogeneration system: Working fluid selection model and multi-criteria decision analysis

As the globe faces major difficulties such as climate change, environmental pollution, and limited energy resources, improving energy efficiency and decreasing the environmental effects of energy systems have become research priorities. A novel mass integration cogeneration (MICHP) system is proposed in this paper. In addition, a mathematical model relating the basic physical properties of the working fluid to the system's performance has been developed. R1233zd(E), R1224yd(Z), R601a, R245fa, and acetone have been chosen to be applied to the MICHP to confirm the model's accuracy. By utilizing the technique for order preference by similarity to an ideal solution, the entropy weight method, and energy, exergy, economic, and environmental analyses of the MICHP, the general efficiency of the working fluid is further explored. The results show that the intermediate heat exchanger is the largest exergy destruction equipment in the system. R601a has the highest return on investment of 0.53, and the annual operating cost is found to be proportional to the latent heat of the working fluid. R1233zd(E) has the lowest environmental impact, with a total equivalent warming impact of −4.89 × 106 kgCO2eq. The multi-criteria decision analysis of the working fluid agrees with the order of the proposed mathematical model's results, proving the model's accuracy. Consequently, the mathematical model can provide a helpful technique guide for working fluid selection in cogeneration systems.

Firms’ cost structure and stock return volatility

PurposeThis paper proposes a framework to identify a pattern in the relationship between firms’ cost structure (i.e. fixed versus variable) and their volatility in stock returns.Design/methodology/approachOur empirical analysis is based on a panel data regression where we use an extended sample period and a time-series regression-based elasticity measure of operating leverage.FindingsWe document significantly higher systematic risk among firms with large fixed costs, a conclusion which confirms theoretical predictions of earlier studies. In new findings, we document high firm-specific risk and high stock return volatility among firms with a fixed cost structure.Originality/valueThe paper fills a gap in the literature by examining the effect of cost structure using various operating leverage measures and other control measures for firm characteristics on idiosyncratic risk. Studies that seek to explain firms’ systematic risks are numerous; conversely, there are relatively fewer studies on the determinants of firms’ specific risks.

How retailers can gain more profitability driven by digital technology: Live streaming promotion and blockchain technology traceability?

Live streaming in e-commerce often faces challenges like counterfeit products and high return rates. To mitigate this issue, retailers can adopt blockchain technology for product traceability to enhance consumer trust, i.e., blockchain-traceable products may be sold in live streaming. Our paper presents three analytical models under various return policies to explore how live streaming and blockchain technology interact in e-commerce. Retailers can invest in live streaming with influencers to attract consumers and in blockchain technology to reduce product returns, benefiting from a demand-enhancing effect and a price-enhancing effect, respectively. The retailer’s investment strategy between live streaming and blockchain technology depends on the interactions of these two effects, moderated by the retailer’s budget type, the market commission level of live streaming, and the traceability cost of blockchain technology. For budget-constrained retailers, live streaming and blockchain technology act as substitutes. When the commission level is low (high) and the traceability cost is high (low), the demand-enhancing (price-enhancing) effect dominates the price-enhancing (demand-enhancing) effect, thus the retailer invests in live streaming (blockchain technology) as a substitute for blockchain technology (live streaming). Conversely, for budget-unconstrained retailers, they may act as complements, prompting investment in both when commission levels and traceability costs are low. The retailer does not invest in either when both the commission level and traceability cost are high. We extend our results to a full refund policy to show the robustness of our result and find that it reduces the retailer’s incentive to invest in live streaming or blockchain technology.

Research on the Correlation Between Improved Corporate Composite Scores and Stock Prices in the Context of Carbon Neutrality

The stock market attracts many investors because of its high risk and high return characteristics. Therefore, it is of strong practical value to find a scientific and effective evaluation method for listed companies and explore its relationship with stock prices. This article combines the financial and non-financial data of listed companies from 2020 to 2023 to provide a composite score for companies based on the improved Wall Marking Way, and uses the Pearson correlation coefficient and regression analyses to investigate the correlation between the score on stock value. It is found that there is a significant positive correlation between comprehensive score and stock price, which proves the feasibility of the scoring method. On this basis, this article further explores the relationship further through regression analysis. The experimental results provide a scientific and reasonable index for evaluating the comprehensive ability of enterprises, and also provide an important reference basis for investors' investment decisions.

Wild Genetic Resource in Vegetable Improvement: Applications and Strategies

Domestication of feral types of the present-day cultivated types was in vogue in earlier days of farming followed by the selection and hybridization that led to many improved varieties. Expression of traits faded due to the development of homozygosity due to repeated interventions in the same set. Relying on wild relatives that are found to be the source of many target genes is found significant. While, this is not so easy, because of the barriers that reside in distant hybridization, consequences like failure in zygote and embryo formation, embryo death, linkage drags, and incompatibility within wild and cultivated groups, etc are need of concern. Strategies like bridge crosses, somatic hybridization, grafting, embryo rescue, etc., techniques are solely or in combination can combat these issues. Vegetables are the group of crops that are mainly cultivated for their high returns and quality aspects for the healthy food routine of the consumer. This review will spotlight the recent advances in vegetable improvement through their wild relatives and available strategies to overcome the barriers to the usage of wild relatives in vegetable improvement, meanwhile the conservation of these resources for the future utilization in vegetable improvement.

Parametric Synthesis of Single-Stage Lattice-Type Acoustic Wave Filters and Extended Multi-Stage Design.

This study proposes a single-stage lattice-type acoustic filter using an analytical solution method for either a narrow passband filter or a wider passband filter using two kinds of parameter assignments in the Butterworth-Van Dyke (BVD) model. To achieve the goal of a large bandwidth or high return loss, two first-order all-pass conditions are used. For multi-stage lattice-type filters, the cost function is defined and design parameters are extracted by using pattern search, while the initial values are provided through single-stage design to shorten optimization time and allow convergence to a better solution. This method provides the S-parameter frequency response for the filter on the YX 42° cut angle of lithium tantalate (electromechanical coupling coefficient of about 6%) that can meet the system specifications as much as possible. Finally, the three-stage lattice-type was applied to various 5G bands with a fractional bandwidth of 2-5%, resulting in a passband return loss of 10 dB and an out-of-band rejection of 40 dB or more.

Design of high flexible multi-band conformal printed patch antenna for sub 6 GHz 5G-based vehicular communication

ABSTRACT Vehicular communications (VCs) play a major role in intelligent transportation systems (ITS). In addition to preventing unintentional collisions and traffic jams, this system can lower fuel and energy usage in the transportation system. The Internet of Vehicles emerges by integrating the IoT with vehicles for smooth communication. In IoV, vehicular communications may be from vehicle to infrastructure (V2I), vehicle to vehicle (V2V), vehicle to pedestrian (V2P), and vehicle to network (V2N) or vehicle to roadside unit (V2R). The antenna used in vehicular communication has some problems, such as less efficiency and high return loss. The frequency response in the existing methods should not give sufficient data for selecting a better band. To avoid this kind of issue and improve the performance by selecting a better frequency band, this work presents a highly flexible multi-band conformal printed patch antenna for sub-6 GHz 5 G-based vehicular communication application. The substrate used to design the antenna is polyimide, and the microstrip patch antenna is designed with cross-shaped slots. The multi-band circularly polarised antenna is designed to operate in vehicular communication bands such as 2.4 GHz, 4.7 GHz, 5.3 GHz, and 5.9 GHz. The proposed work is simulated in HFSS, and the results of directivity, gain, reflection coefficient, Voltage Standing Wave Ratio (VSWR), radiation pattern, axial ratio, Left-Hand Circular Polarisation (LHCP), Right-Hand Circular Polarization (RHCP) and surface current distribution are evaluated for the conformal antenna.

Сравнительная картина и проблемы иностранного портфельного инвестирования в реальном секторе экономики / Comparative picture and problems of foreign portfolio investment

The article is devoted to the comparative picture and problems of foreign portfolio investment in the real sector of the economy. The article analyzes the main obstacles that arise in the process of attracting foreign portfolio investments. The factors influencing the increase in the flow of foreign portfolio investments, the possibility of their rapid attraction and effective distribution are considered. Sustainable development of the economy of any country today is impossible without active participation in world economic relations. Along with international trade, international flows of investment capital, carried out on the basis of effective cooperation between countries, are becoming increasingly important. In recent years, the issue of attracting external capital to the Armenian economy has become topical. Foreign investment is one of the most important conditions for stabilization and growth of the country's economy. This is primarily due to the fact that firms’ own financial resources are limited, which is due to a number of reasons in Armenian reality, such as high return on invested capital, high taxes, etc. The movement of global financial capital through the channels of the global financial system occurs in various forms, among which international portfolio investments, including investments in equity and debt securities, occupy a special place. Financial globalization is accelerating the trend towards expanding the market segment of international portfolio investments.

Does digital transformation in enterprises reduce debt default risk?

With the rapid advancement of digital technology, the digital transformation of enterprises has become essential for enhancing competitiveness and achieving sustainable development. This paper aims to systematically examine the impact of digital transformation on debt default risk, using A-share listed companies from 2010 to 2022 as the research sample. The findings indicate that digital transformation significantly reduces the risk of debt default, and this conclusion is supported by a series of robustness tests. Heterogeneity analysis based on firm-specific characteristics reveals that companies with higher returns on assets, higher R&D investment, larger scale, higher debt-to-asset ratio, greater regional social trust, and higher information transparency experience a more pronounced risk mitigation effect from digital transformation. Mechanism tests demonstrate that digital transformation primarily lowers debt default risk through two channels: alleviating financing constraints and improving total factor productivity. Digital transformation more effectively reduces corporate debt default risk through foundational technologies compared to practical applications. These conclusions contribute to a deeper understanding of how digital transformation drives high-quality development in enterprises and provide a comprehensive assessment of the implementation effects of digital transformation.

Who should pay for the return freight in e-commerce? Platforms, retailers or consumers

In the realm of e-commerce, various return freight modes are available, such as platform-bearing return freight (PP strategy), retailer-bearing return freight (RP strategy), and consumer-bearing return freight (CP strategy). The return freight strategy adopted by platforms plays a crucial role in responding to consumer behaviors. To analyze how platforms determine the optimal return freight strategies, we examine a supply chain comprising a platform, a retailer, and heterogeneous consumers, employing a Stackelberg game model to capture their decision dynamics. Our findings suggest that the platform should opt for the PP strategy only when the product profit margin is relatively low. If the platform refuses to adopt the PP strategy, then the RP strategy is preferable when consumers face extremely high consumer return freight costs; otherwise, the CP strategy is the equilibrium result. We also prove that the selection of the return freight strategies leads to changes in the property of the equilibrium. Under the CP strategy, how the product fit probability affects the optimal price depends on the procurement cost; while under the RP and PP strategies, the optimal price decreases with the fit probability. Moreover, under the PP strategy, an increase in the product fit probability does not always benefit the platform. Further, our analysis reveals that, while the PP strategy can reduce the retailer’s risk, it might negatively impact supply chain performance, which implies that cost sharing in the supply chain does not necessarily lead to a higher channel profit. We also investigate how the platform’s return freight strategies affect consumer surplus and identify regions for Pareto improvement where all parties benefit from the PP strategy. Finally, by exploring extensions like positive salvage values, partial refunds, platform competition, and differentiated return freight costs, we confirm the robustness of our findings and unveil new insights.

Trochleoplasty and à-la-carte procedures for patellar instability in young and active patients: Clinical outcomes at minimum 2 Years follow-up

IntroductionPatellar instability is a common condition affecting approximately 6 individuals per 100,000, but among adolescents, this incidence is notably higher. Trochlear dysplasia has been recognized as the pathoanatomic risk factor exerting the most significant biomechanical influence. Over time, various surgical techniques have been developed to address trochlear dysplasia. The purpose of this study is to evaluate the clinical outcomes, return to sport, as well as complications and re-operation rate of sulcus deepening trochleoplasty performed in a cohort of young and active patients using the Bereiter technique. Materials and methodsBetween January 2019 and February 2022, 11 cases of recurrent patellar dislocations underwent trochleoplasty. Preoperative radiological assessment included X-rays, CT scans following the Lyons and MRI. Inclusion criteria for the study and trochleoplasty indications included patients aged 10–25 with recurrent patellar dislocations unresponsive to nonoperative treatment and minimum type B trochlear dysplasia. Clinical follow-up occurred at 1-3-6 months and annually, with control X-rays at these intervals. Patient-reported outcome scores included the Knee Society Score, Kujala score, and Karnofsky performance status scale. ResultsBetween January 2019 and February 2022, 11 patients underwent trochleoplasty and were included in this study. Preoperative radiological measurements indicated mean values: sulcus angle (152.5°), trochlear depth (3.4 mm), Caton-Deschamps index (1.2), tibial tuberosity to trochlear groove (TT-TG) distance (17.5 mm), external patellar tilt angle (6.8°), femoral anteversion (11.5°), and tibial torsion (32°). All patients were followed up for at least 2 years, with an average of 43 months. Concurrent surgeries included tibial tuberosity transposition (100 %), MPFL reconstruction in 9 cases (81.8 %) and 2 patients also underwent division of the external alar ligament (18,2 %). PROMs at final follow-up showed mean values: Knee Society Score (KSS) (80.5), Kujala score (88.3), and Karnofsky performance status scale (88.8). Return to sport was reported by all active patients. Three cases required secondary surgical intervention for removal of the screws. ConclusionTrochleoplasty, especially with the Bereiter "thin flap" approach, improves patellofemoral congruency. Combining trochleoplasty with tibial tuberosity transposition addresses mal-tracking related to severe dysplasia and other à-la-carte procedures like medial patellofemoral ligament (MPFL) reconstruction enhance stability. In young and active patients, it resolves instability issues and reduces the likelihood of further dislocations with high return to sport rates.

Paratenon preserving repair of the midsubstance acute Achilles tendon rupture: a systematic review and meta-analysis with best- and worst-case analyses for rerupture rates.

Paratenon preserving techniques to facilitate acute Achilles tendon rupture repair (AATR) functions by maintaining vascularity and biology for optimal healing response. Therefore, the purpose is to evaluate the outcomes following paratenon preserving repair of the midsubstance AATR. The hypothesis was that paratenon-preserving techniques demonstrate high return to play rates and low complication rates for the repair of the midsubstance AATR. A systematic review of the PubMed, Embase, and the Cochrane Library databases was performed by two authors using specific search terms and eligibility criteria. The assessment of the evidence was two-fold: level and quality of evidence. A meta-analysis of proportions for the various complication rates was performed using the restricted maximum likelihood method following the Freeman-Tukey double-arcsine transformation. Fixed effects models were employed if I2 < 25% (low heterogeneity), and random effects models were employed if I2 ≥ 25% (moderate to high heterogeneity). The pooled return to play rate was 90.3%. The pooled rerupture rate as reported was 0.9% (best-case scenario 0.8% and worst-case scenario 6.8%). No meaningful subgroup analysis for rerupture rates could be performed based on the meta-regression. The pooled complication rate other than reruptures was 4.8%. The pooled infection rates were 0.3%, DVT rates were 1.6%, and sural nerve injury rates were 0.3%. Paratenon preserving techniques that are minimally invasive in nature demonstrated safe and favorable outcomes with high return to play rates and low complication rates for the repair of the midsubstance AATR.

Study on the motivation of enterprise greenwashing behavior based on the perspective of environmental commitment implementation

With the rapid economic growth, the issue of ecological environmental protection has been widely concerned by the public, and has triggered diversified discussions. As the main participants in social and economic activities, enterprises play a pivotal role in this issue, not only bearing social responsibility, but also playing a decisive role in environmental protection practices. In the context of consciously undertaking social responsibilities and responding to institutional requirements, enterprises often express their firm position and commitment to environmental protection and compliance with laws and regulations through information disclosure. In practice, some enterprises run counter to their environmental protection commitments, choosing to "low investment, high return" as the goal of greenwashing behavior. Taking Hegang as the research object, this paper summarizes the process of implementing environmental commitment as the result of the joint action of two factors: implementation ability and implementation motivation. Then, the paper analyzes the major environmental pollution cases of Hesteel, analyzes the motivation of Hesteel's greenwashing behavior from the perspective of the implementation ability and implementation motivation of environmental commitment, and finally puts forward corresponding suggestions for the shortcomings of the enterprise itself and external regulatory departments in preventing greenwashing behavior, in order to optimize the governance mechanism and improve regulatory efficiency.

Study on performance of a multi-heat source heat pump coupled energy storage system for plant factory heating system

CO2 air source heat pump (CASHP) faces challenges of performance degradation caused by the high return water temperature and the low ambient temperature for building heating. This study proposed a novel multi-heat source heat pump system (MHSHP) that combined with a CO2 air source heat pumps (CASHP) and ground source heat pumps (GSHP) with the implementation of a thermal storage tank. The performance and CO2 emissions of both CASHP and MHSHP systems were investigated by applying a plant factory located in Beijing, China. The effects of user-side parameters and ambient temperature were explored with the storage water temperatures ranging from 20 °C to 40 °C. The results demonstrated that the heating performance of the CASHP improved with an increase of user water flow rate and ambient temperatures, while it decreased as the storage water temperature increased. At the flow rate of 1.1 m3/h, the increase of the compressor frequency from 40 Hz to 60 Hz led to a significant improvement in heating capacity by 53.3 %, and a reduction in COP by 23.3 %. When the user-side water flow ratio decreased or the total flow rate increased, the COP of the MHSHP system showed improvement and outperformed that of the CASHP system, with an increase ranging from 46.9 % to 61.5 %. Additionally, it exhibits reduced sensitivity to ambient temperature fluctuations, resulting in a decrease in COP variability from 33.3 % to 20.6 %. Moreover, the CO2 emissions of the system decrease as the COP increases, with significant reduction of 69.2 %.
