The impact of CEO founder and CEO age on new ventures performance: A quantile regression analysis for U.S. IPOs
Authors: Wu Shuai , Zhu Jinfeng , Wu Tingting 
Published: January 2025

Using quantile regression, we compare the relationship between CEO founder and CEO age and the performance of new firms in the US. Our empirical evidence shows that issuers led by a CEO founder have a strong positive impact on first-day returns, especially at the intermediate level of underpricing, while underpricing declines as CEO age increases, especially above the 40th percentile, which would not be confirmed by a classical linear regression. This finding suggests that estimating the different quantile effects of a response variable may be more informative than estimating only the average effect of the response variable. In addition, CEO founders exacerbate uncertainty about issuer quality with firm expansion; and in large firms, mature CEOs perform better than young ones in reducing the first trading day return; the mature CEO has a strong negative impact on initial returns only in low-R\&D firms, and the CEO founder has a significant positive association with underpricing in R\&D-intensive firms.
Comparamos la relación entre el CEO fundador y la edad del CEO con los resultados de las nuevas empresas en EE. UU., aplicando una regresión cuantil. Nuestra evidencia empírica revela que las empresas lideradas por un CEO fundador tienen un fuerte impacto positivo en los rendimientos del primer día, especialmente en el nivel medio de infravaloración; mientras que la infravaloración se reduce a medida que aumenta la edad del CEO, especialmente por encima del percentil 40, algo que la regresión lineal clásica dejaría sin confirmar. Este hallazgo indica que, en comparación con la estimación del efecto medio de la variable de respuesta, la estimación del efecto de los distintos cuantiles de una variable de respuesta puede ser más perspicaz. Además, los consejeros delegados fundadores exacerban la incertidumbre sobre la calidad de los emisores con la expansión de las empresas; y en las grandes empresas, los consejeros delegados maduros obtienen mejores resultados que los jóvenes a la hora de reducir la rentabilidad del primer día de cotización. El consejero delegado maduro tiene un fuerte impacto negativo en la rentabilidad inicial solo en las empresas de baja intensidad de I+D, y el consejero delegado fundador tiene una asociación positiva significativa con la infravaloración en las empresas de intensidad de I+D.

Natural plants have always been a very potent source of pharmaceuticals; Indians in particular have been employing a variety of plants, as well as their parts and extracts, for medicinal purposes since the Vedic era. The current study aims to assess the antiepileptic activity of a nanoemulsion made from Soymida febrifuga leaf extract. The Soxhlet device is used to perform the extraction. The ethanol extract was used at dosages of 2000 mg/kg, 1000 mg/kg, 900 mg/kg, 850 mg/kg, 800 mg/kg, and 750 mg/kg for the acute toxicity test. The Soymida febrifuga sample's IR spectra showed that the absorption peaks of different functional groups are consistent with reference spectra. The particle stability index is represented by the zeta potential. The prevention of particle aggregation depends on this stability. The improved formulation's zeta potential was the millivolt (mV) was discovered. The stability of nanoparticles is higher at higher zeta potential maximum. The release study was conducted in accordance with the steps outlined in the section on materials and procedures. The medication was required for the slow, continuous release of the medicine. In the 12-hour release testing, F6, out of the nine formulations, had the highest drug release value. In convulsion models generated by MES and PTZ, the chloroform extract of Soymida febrifuga delayed the onset and decreased the duration of convulsions. It can be utilized as an adjuvant therapy against cognitive deficiency in convulsions.

Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children, and it as one of the most serious public health problems of the 21st century. Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility. Dieting and physical exercise are the mainstays of treatment for obesity. Diet quality can be improved by reducing the consumption of energy-dense foods such as those high in fat and sugars, and by increasing the intake of dietary fiber. Since obesity has grown to epidemic proportions, its effective management is a very important clinical issue. Despite the great amount of scientific effort that has been put into understanding the mechanisms that lead to overconsumption and overweight, at the moment very few approaches to weight management are effective in the long term. On the other hand, modern society is also affected by the growing incidence of eating disorders on the other side of the spectrum such as anorexia and bulimia nervosa which are equally difficult to treat. This review summarises the current available scientific literature regarding the effect of NUTREASE POWDER, The Nature, sblend of protein, Fibers, plant extracts (phytochemicals) in human appetite and body weight.

Published: January 2025

A simple, sensitive, and precise RP-HPLC method for the simultaneous estimation of Sitagliptin (SIT) and Simvastatin (SIM) combined dosage form has been developed and validated. The components were well separated using Agilent C8 (4.6 x 150mm, 3.5µm) column using phosphate buffer (ph-6.26): Acetonitrile in the ratio 25:75 as mobile phase at a flow rate of 0.8 mL/min. The eluents were detected at 254 nm using UV detector. The retention times of SIT and SIM were found to be 2.475min and 6.528min for Simvastatin and Sitagliptin respectively. The linearity was observed in the range of 80-120 µg/mL for SIT and 16-24µg/mL for SIM. The marketed dosage form was analyzed by using the developed method and the percent content of SIT and SIM were found to be 99.67 – 100.27 % and 99.42 – 100.54%. The developed method was validated for parameters like system suitability, specificity, linearity, accuracy, precision, ruggedness and robustness as per ICH guidelines and the results were found to be within the limits. The validated method was used for the stability studies (short, long and auto sampler) and forced degradation studies (acidic, alkaline, oxidative and photolytic). Both SIT and SIM were found to be stable in all conditions. This validated method can be used for the routine quality control testing of SIT and SIM combined dosage form.

The studies regarding the effectiveness of teaching using a mobile phone on students’ vocabulary mastery are widely discussed. While the process of how students acquire that vocabulary from a mobile phone is barely touched. That’s why the purpose of this study is to investigate the process of students acquiring English vocabulary from mobile phone use and whether the students comprehend the meaning of the vocabulary that they acquire or not. The design of this study employed study case design. The subject of this study was 7 students at a fourth-grade elementary school. The observation and interview were used for data collection. The research results demonstrated that mobile phone has great potential as an instructional tool for acquiring English vocabulary. The findings also indicated that the process of acquiring English vocabulary is caused by two factors. The first is psycholinguistic factors and the second is social factors. The finding indicated that the psycholinguistic factors hold the significant one. It can be seen from the repetition and exploration done by their own self in acquiring the English vocabulary. While the social factor such as people around them (their parents and friends) have less contribution in assisting them in acquiring the English vocabulary. Regarding the comprehension of vocabulary that they acquired, the findings suggested that three students understand and know the real meaning of most of the English vocabulary that they gained from daily mobile phone use, while the rest (four) students knew the words only based on words function without knowing the real meaning of each English word. Generally, findings clearly showed that mobile phones facilitated students in acquiring English vocabulary independently.

Authors: Ofayani Desi 
Published: January 2025

Exploring students background knowledge in pre-reading activities suggests the importance of interaction in the process of meaning making which requires appropriate vocabulary. Although many factors constitute students’ comprehension, vocabulary should be the main concern in EFL reading classes. Consistence with this premise, the current study was aimed at proving the correlation between students’ vocabulary mastery and their reading comprehension at tenth grade students of SMAN 1 Kramatwatu. This correlational study involved 37 students taken through purposive random sampling. Vocabulary and reading tests were employed to determine the correlation between students’ vocabulary mastery and their reading comprehension. Based on the results of the research, it could be noticed that the R-count > R-table (0.357 > 0.324) which means that H0 was rejected and H1 was accepted. In conclusion, there was a low correlation between vocabulary mastery and reading comprehension at tenth grade students of SMAN 1 Kramatwatu.

Semakin terjangkau dan banyaknya ruang publik yang menyediakan akses internet gratis membawa dampak positif dan negatif bagi para pelajar dari kelompok marginal. Di satu sisi internet memberikan kemudahan dalam mengakses informasi, namun kurangnya pendampingan dari orang tua dan lokasi tempat tinggal dan sekolah yang berada di sekitar terminal membuat mereka rentan mengalami kekerasan di dunia nyata maupun maya. Pelajar dari kelompok marginal memiliki resiko yang lebih tinggi untuk terlibat dan menjadi korban dari ujaran kebencian dibandingkan pelajar yang berada di lingkungan yang lebih kondusif. Kegiatan Pengabdian kepada Masyarakat ini dimaksudkan untuk meningkatkan pemahaman pelajar dari kelompok marginal mengenai literasi media dan ujaran kebencian di media sosial. Kegiatan ini dilakukan dalam bentuk ceramah interaktif dan diskusi dengan menggunakan media pembelajaran berupa power point, video, stand banner dan poster. Metode untuk mengukur keberhasilan kegiatan dilakukan melalui observasi, wawancara, pre-test dan post-tes. Hasil kegiatan menunjukkan peningkatan pemahaman pelajar mengenai literasi media, ujaran kebencian dan kemampuan mengidentifikasi bentuk-bentuknya, dan juga kemampuan mengidentifikasi akun dan cara melaporkan akun pelaku ujaran kebencian. Kegiatan ini juga menemukan, bahwa status sebagai kelompok marginal tidak menjadikan mereka rentan mengalami ujaran kebencian berdasarkan kelas sosial. Hal ini karena komunikasi melalui media sosial dilakukan secara termediasi, memungkinkan penggunanya untuk anonim, dan membentuk identitas virtual. Walaupun demikian, kurangnya pendampingan dari orang tua dan lingkungan tempat tinggal yang kurang kondusif menjadikan mereka lebih rentan mengalami dampak negatif dari media sosial dan ujaran kebencian

Published: January 2025

AIM: Patient specific pre-contoured rods (PSRs) represent a relatively new technological development aimed at improving surgical outcomes and reducing complications in adult spinal deformity surgery. To date, only a limited number of studies have been published comparing PSRs with traditional spinal rods. In this paper, we compare the surgical, imaging, and clinical outcomes of PSRs and traditional spinal rods in a single-center case-matched study.
METHODS: Thirty cases of adult spinal deformities (ASD) were retrospectively analysed. These included 10 patients who were operated on using UNiD™ (Adaptive Spine Intelligence, MedTronic, Minneapolis, MN, USA) PSRs and 20 operated on using traditional rods from January 2023 to August 2023. Minimum post-surgical follow-up was 6 months. General demographics and standard radiographic parameters, as well as Scoliosis Research Society (SRS)-22, Oswestry Disability Index (ODI) and Short Form Health Survey (SF-12) Scores, were measured at pre-operative examination and at 6-month follow-up. Follow-up imaging data were compared with software-planned correction goals. Intra-operative data and complications were also recorded.
RESULTS: Patients in the two groups were matched in terms of age, body mass index (BMI), sex, type and severity of spinal deformity. The magnitude of the coronal deformity (p = 0.812) and preoperative sagittal imbalance (p = 0.845) were similar between the two groups. The number of fused levels (p = 0.439), osteotomies (p = 0.188), implant density (p = 0.880), and surgery duration (p = 0.299) were similar between the two groups. Sagittal correction goals set during preoperative planning were achieved in the PSRs group, with the exception of pelvic tilt (PT) (p = 0.042). In contrast, PT (p = 0.040), L1-S1 lordosis (p = 0.032) and global tilt (GT) (p = 0.001) remained significantly undercorrected in the control group at 6-month follow-up. Clinical outcomes (ODI and SF-12 Scores) and complication rates were similar between the two groups.
CONCLUSIONS: The use of PSRs improves the achievement of better post-operative spinopelvic alignment in adult spinal deformity surgery. Moreover, no significant differences were noted in terms of complications, operative times, and clinical outcomes compared to traditional spinal rods at 6-month follow-up.
