Measuring Efficiency Of Family And Non-Family Firm Amidst Covid-19 Times: Do They Perform Differently?
Authors: Wibowo Hadi , Manurung Adler Haymans , Sembel Roy , Wybawa Erika Pritasari
Published: March 2024

The outbreak of COVID-19 pandemic in early 2020 has inflicted serious financial distresses for most firms in multi-sectoral industries. Each of them was enforced to deal with the economic downturns by working more efficiently. In this case, family and non-family firms might perform differently to protect themselves from bankruptcy. This research aims to measure firm efficiency by employing a total of 52 entities listed on Indonesia Stock Exchange (IDX), 26 entities for each type of firms from 2019 to 2022, reflecting the times before, during, and after the pandemic. At the first stage, date envelopment analysis (DEA) with constant return-to-scale (CRS) input-oriented approach is employed to generate deterministic efficiency scores of each sample which the bias is then corrected using Simar and Wilson’s bootstrap technique. At the second stage, hypothesis testing is conducted to examine whether the difference in efficiency score between both types of firms is significant. The result shows that family and non-family firms do not perform differently during a 4-year of research period (p-value=0.136). Nevertheless, family firms exhibit a significant drop in 2020 (p-value=0.0061), where this condition reversed with a significant increase in 2021 (p-value=0.0002). Non-family firms perform more stably throughout the research years. Finally this research may contribute to the development of organization-related science, business, and strategic management. The way most family firms operate might reflect the socio-cultural attributes of a nation. There is no other similar study found since COVID-19 pandemic is still considered as a relatively new global health crisis.

Authors: James Mariba Kerangani , Akoth Akinyi Joy , Indiya Gulali Donald
Published: March 2024

According to Makori, M. & Kariuki, N., (2015), a study was conducted in Presbyterian University of East Africa (PUEA) by the HR Office in 2014 and disclosed that about 50% of employees in Kenyan institutions of Higher Learning merely come to work to do what is needed of them. The study showed that 47% of workers came to work and ended up using most of their time on social websites during work hours. Hence workforce turnover was registered at 43%. The major cause of these situations is not known. Scholars have given many suggestions that some Occupational changes in private universities are linked with digitalization, how information is shared, relocation of workers, change in task objectives and production costs. Nevertheless, it is not known whether these changes have any significant effect on employee engagement in Kenyan private universities. This study therefore was particularly concerned with the Effect of Occupational Transfers on Employee Engagement in Private Universities in Western Kenya. The conclusions of this study might be very useful to many stakeholders involved in the management of Private universities in Kenya. The study was based on the Job Characteristics theory. Correlational research design was used. Target population was 1440 workers of four selected Private Universities. Stratified random sampling techniques were employed. The sample of 313 workers from different sections was used. Questionnaires were given to Respondents to complete for the purpose of data collection. Questionnaire were developed using items from literature reviews. SPSS and Excel tools were used during the data analysis process. Data was presented using charts and Frequency tables. From the results, conclusions and recommendations were made. A pilot study was carried out with 10 respondents from Uzima University to assess the validity of the research instruments. The 10 respondents were not involved in the main study. The results revealed that occupational transfers had a negative effect (β=-.541, p<.05) and accounted for 29.3% variance in employee engagement (R2=.293, p<.05). It was concluded that Occupational Transfers have a significant effect on employee engagement. The study suggested that private universities in western Kenya should communicate to their employees before they are transferred.
Decoding the Signifiers of Plastic Surgery: A Semiotic Analysis
Authors: Aliyatur Ika , Duwila Shanty , Setyowati Yulis
Published: March 2024

This study utilizes Charles Sanders Peirce's semiotic framework, concentrating on the interpretation of signifiers associated with plastic surgery. A particular emphasis is placed on the "Male Rhinoplasty" page as a case study, where icons, indexes, and symbols embedded in both images and texts are scrutinized across different sections of the website. Employing a qualitative approach, the study involves meticulous analysis of ten images extracted from the "Male Plastic Surgery" page. Among these, the study identifies 13 icons, 12 indexes, and 18 symbols, all of which serve as visual cues to not only enrich user experience but also evoke emotional responses that engage potential patients. The implications of these findings underscore the comprehensive communication strategy employed by ID Hospital's website. By adeptly incorporating Peirce's semiotic principles, the website constructs a multifaceted narrative concerning male rhinoplasty that is both visually captivating and emotionally resonant. This research not only sheds light on the semiotic complexities within the realm of plastic surgery communication but also provides insights into how websites can effectively employ visual and textual elements to convey intricate messages.

The Spectral Energy Distributions and Bolometric Luminosities of Local AGN: Study of the Complete 12 μm AGN Sample
Authors: Spinoglio Luigi , Fernández-Ontiveros Juan Antonio , Malkan Matthew A.
Published: March 2024

We measure the bolometric luminosity of a complete and unbiased 12 μm-selected sample of active galactic nuclei (AGN) in the local Universe. For each galaxy, we used a 10-band radio-to-X-ray spectral energy distribution (SED) to isolate the genuine AGN continuum in each band, including subarcsecond measurements where available, and correcting those contaminated by the host galaxy. We derive the median SED of Seyfert type 1 AGN, Seyferts with hidden broad lines (HBLs), Seyferts of type 2, and LINER nuclei in our sample. The median Seyfert 1 SED shows the characteristic blue bump feature in the UV, but nevertheless, the largest contribution to the bolometric luminosity comes from the IR and X-ray continua. The median SEDs of both HBL and type 2 AGN are affected by starlight contamination in the optical/UV. The median SED of HBL AGN is consistent with that of Seyfert 1s, when an extinction of A

V
∼ 1.2 mag is applied. The comprehensive SEDs allowed us to measure accurate bolometric luminosities and derive robust bolometric corrections for the different tracers. The 12 μm and K-band nuclear luminosities have good linear correlations with the bolometric luminosity, similar to those in the X-rays. We derive bolometric corrections for either continuum bands (K band, 12 μm, 2–10 keV, and 14–195 keV) or narrow emission lines (mid-IR high-ionization lines of [O iv] and [Ne v] and optical [O iii] 5007 Å) as well as for combinations of IR continuum and line emission. A combination of continuum plus line emission accurately predicts the bolometric luminosity up to quasar luminosities (∼1046 erg s−1).
Insights into dengue transmission modeling: Index of memory, carriers, and vaccination dynamics explored via non-integer derivative
Authors: Jan Rashid , Ahmad Imtiaz , Ahmad Hijaz , Vrinceanu Narcisa , Hasegan Adrian Gheorghe
Published: March 2024

It is acknowledged that dengue infection has a significant economic impact due to healthcare costs and lost productivity. Research can provide insights into the economic burden of the disease, guiding policymakers in their allocation of resources for prevention and control interventions. In this work, we structured a novel mathematical model that describes the spread of dengue with the effects of carriers, an index of memory and vaccination. To show the effect of treatment on the dynamics of dengue, we have incorporated medication-related treatment into the system. The proposed dynamics are represented by using fractional derivatives to capture the role of memory in the control of the infection. We introduced the fundamental principles and notions of non-integer derivatives for the analysis of the model; moreover, the existence and uniqueness results for the solution of the system have been established with the help of mathematical skills. The theory of fixed points has been utilized for the analysis and examination of the system. We have established Ulam-Hyers stability for the recommended system of dengue infection. Regarding the numerical findings, a numerical method is presented to highlight the solution pathways for the system of dengue infection. Several simulations have been performed to visualize the contribution of the input parameters of the system to the prevention and control of the infection. The index of memory, vaccination, and treatment are suggested to be attractive parameters which can reduce the level of infection while the biting rate, asymptomatic carriers and transmission rate are critical as they can increase the risk of the infection in society. Our findings not only provide information for the effective management of the infection they also possess valuable insights that can improve public health.
On Schrödinger-Poisson equations with a critical nonlocal term
Authors: Zhang Xinyi , Zhang Jian
Published: March 2024

In this paper, we study the following non-autonomous Schrödinger-Poisson equation with a critical nonlocal term and a critical nonlinearity:

   \begin{document}$ \begin{equation*} \left\{\begin{aligned} & -\Delta u +V(x) u + \lambda \phi |u|^3 u = f(u) + (u^+)^5,\ \ {\rm in } \ \ \ \ \mathbb{R}^3,\\ & -\Delta \phi = |u|^5, \ \ {\rm in } \ \ \ \ \mathbb{R}^3. \end{aligned}\right. \end{equation*} $\end{document}

First, we consider the case that the nonlinearity satisfies the Berestycki-Lions type condition with critical growth. Second, we consider the case that $ \mathrm{int}V^{-1}(0) $ is contained in a spherical shell. By using variational methods, we obtain the existence and asymptotic behavior of positive solutions.

Published: March 2024

In this paper, we introduce novel extensions of the reversed Minkowski inequality for various functions defined on time scales. Our approach involves the application of Jensen's and Hölder's inequalities on time scales. Our results encompass the continuous inequalities established by Benaissa as special cases when the time scale $ \mathbb{T} $ corresponds to the real numbers (when $ \mathbb{T = R} $). Additionally, we derive distinct inequalities within the realm of time scale calculus, such as cases $ \mathbb{ T = N} $ and $ q^{\mathbb{N}} $ for $ q > 1 $. These findings represent new and significant contributions for the reader.

Authors: Franzini-Armstrong Clara
Published: March 2024

This presentation reviews images of electron micrographs from various skeletal muscles identifying a consistent association of diydropyridine receptors (DHPR) tetrads with  alternate ryanodine receptors. Imaging of the junctional gap in triads from various sources  provide direct evidence for the  association of four diydropyridine receptors (DHPRs), clustered into tetrads, with alternate ryanodine receptors (RyRs). It is not clear whether firing of all four components of a tetrad is necessary to fully activate the opening of the RyR channel.

Authors: Stefana Alberto , Fusar-Poli Paolo , Langfus Joshua , Vieta Eduard , Youngstrom Eric
Published: March 2024

The present study reports on the development and validation of the clinician affective response (CARE) scale. The CARE scale was designed as a self-report measure of therapists’ patterns of thoughts, feelings, and behaviors toward the patient during an individual psychotherapy session. An initial pool of 116 items was generated, and its quality was evaluated by subject matter experts. Validation data were gathered from licensed psychotherapists (n=554). We used exploratory factor analysis and item response theory-graded response modeling to select items, confirmatory factor analysis to test how well the factor structure fit the data, and k-fold cross-validation to ascertain the robustness of the model. Criterion validity was evaluated by correlating the scores of the scale with the characteristics of therapists, patients, and treatment. The selected model consists of 15 items and a 3-factor structure, which showed excellent model fit, good internal consistency, and evidence of criterion validity. The CARE scale, short and quick to complete, enables therapists to reflect on and recognize their inner experiences and quantify these experiences in ways conducive to statistical analysis and research. Furthermore, the monitoring of these affective reactions toward their patients can guide therapeutic interventions and inform clinical supervisors.
Intercultural Competence Assessment: What Are Its Key Dimensions Across Assessment Tools?
Authors: Matveev Alexei , Yamazaki Merz Miwa
Published: March 2024

Prior research has identified different dimensions of intercultural competence (IC). However, its focus remains inconsistent across different disciplines and contexts. Existing assessment tools do not focus on all dimensions of Intercultural Competence. Instead, each focuses only on a subset of the IC dimensions. To fill this gap, this study aims (1) to provide a review of currently available assessment tools for IC and (2) to identify a comprehensive list of the key dimensions of IC. This will help researchers agree on a unified definition of IC and develop a measurement of IC that is applicable across contexts and disciplines. The authors find that a comprehensive IC definition and measurement should take into account cognitive (culture-specific knowledge, attitude, open-mindedness/ flexibility, critical thinking, motivation, and personal autonomy), affective (cultural empathy and emotional stability/control), and behavioral (experience, social initiative, leadership, and communication) dimensions.
Cultural Diversity in Meta-Cognitive Beliefs about Learning: Within-European Similarities and Differences?
Authors: van Egmond Marieke , Kühnen Ulrich
Published: March 2024

Previous work on cross-cultural differences in the domain of education, has primarily studied Western (European) and Asian cultures or comparisons thereof. Current internationalization trends in higher education however call for a greater understanding of possible within-European cultural differences in the domain of learning. The current paper therefore addresses the question how culture influences the beliefs of Western and Eastern European students. The studies are based on the theory that the beliefs of students and faculty in the Western cultural context can be characterized as primarily ‘mind oriented’, whereas previous research has indicated that the beliefs of East-Asian academics has a stronger ‘virtue orientation’. In the mind orientation, the development of one’s cognitive thinking skills is at the heart of the concept of learning. In the virtue orientation, learning is primarily seen as a process of social and moral development of the person. Since the psychological literature has not yet reached a consensus on the degree and domains in which cultural differences emerge across the Eastern and Western European regions, a two-fold survey study was conducted in the Eastern European countries of Poland and Russia; and the Western European countries of the Netherlands and Germany. Students from both European regions were found to endorse mind oriented beliefs about learning more strongly than virtue oriented ones on the level of both attitudes and behavioral intentions, pointing to a striking cross-cultural similarity across the European region in the domain of beliefs about learning.

INTRODUCTION: Over the past several years analysis of image has moved from larger system to pervasive portable devices. For example, in pervasive biomedical systems like PACS-Picture achieving and Communication system, computing is the main element. Image processing application for biomedical diagnosis needs efficient and fast algorithms and architecture for their functionality. Future pervasive systems designed for biomedical application should provide computational efficiency and portability. The discrete wavelet transform (DWT) designed in on-chip been used in several applications like data, audio signal processing and machine learning.
OBJECTIVES: The conventional convolution based scheme is easy to implement but occupies more memory , power and delay. The conventional lifting based architecture has multiplier blocks which increase the critical delay. Designing the wavelet transform without multiplier is a effective task especially for the 2-D image analysis. Without multiplier Daubechies wavelet implementation in forward and inverse transforms may find efficient. The objective of the work is on obtaining low power and less delay architecture.
METHODS: The proposed lifting scheme for two dimensional architecture reduces critical path through multiplier less and provides low power, area and high throughput. The proposed multiplier is delay efficient.
RESULTS: The architecture is Multiplier less in the predict and update stage and the implementation carried out in FPGA by the use of Quartus II 9.1 and it is found that there is reduction in consumption of power at approximately 56%. There is reduction in delay due to multiplier less architecture.
CONCLUSION: multiplier less architecture provides less delay and low power. The power observed is in milliwatts and suitable for high speed application due to low critical path delay.

INTRODUCTION: The satellite's physical and technical capabilities limit high spectral and spatial resolution image acquisition. In Remote Sensing (RS), when high spatial and spectral resolution data is essential for specific Geographic Information System (GIS) applications, Pan Sharpening (PanS) becomes imperative in obtaining such data.
OBJECTIVES: Study aims to enhance the spatial resolution of the multispectral Landsat-8 (L8) images using a synthetic panchromatic band generated by averaging four fine-resolution bands in the Sentinel-2 (S2) images.
METHODS: Evaluation of the proposed multi-satellite PanS approach, three different PanS techniques, Smoothed Filter Intensity Modulation (SFIM), Gram-Schmidt (GS), and High Pass Filter Additive (HPFA) are used for two different study areas. The techniques' effectiveness was evaluated using well-known Image Quality Assessment Metrics (IQAM) such as Root Mean Square Error (RMSE), Correlation Coefficient (CC), Erreur Relative Globale Adimensionnelle de Synthèse (ERGAS), and Relative Average Spectral Error (RASE). This study leveraged the GEE platform for datasets and implementation.
RESULTS: The promising values were provided by the GS technique, followed by the SFIM technique, whereas the HPFA technique produced the lowest quantitative result.
CONCLUSION: In this study, the spectral bands of the MS image’s performance show apparent variation with respect to that of the different PanS techniques used.

Background: Older patients are particularly vulnerable to age-related respiratory changes. This prospective randomized controlled trial studied the effects of high and low fractions of inspired oxygen (FiO2) with the recruitment maneuver (RM) during extubation on lung atelectasis postoperatively in older patients undergoing major abdominal surgery.Methods: We randomized a total of 126 patients aged >60 years who underwent both elective and emergency major abdominal surgeries and met the inclusion criteria into three groups (H, HR, and LR) using computer-generated block randomization. Group H received high FiO2 (1), Group HR received high FiO2 (1) with RM followed by a positive end-expiratory pressure of 5 cm H2O, and Group LR received low FiO2 (0.4) with RM followed by a positive end-expiratory pressure of 5 cm H2O 10 minutes before extubation. Oxygenation and atelectasis were measured using the arterial partial pressure of oxygen (PaO2)/FiO2 ratios and lung ultrasound score. Postoperative pulmonary complications were recorded up to 24 hours postoperatively.Results: The mean PaO2/FiO2 at 30 minutes post-extubation was significantly higher in Groups LR and HR compared to that in Group H (390.71±29.55, 381.97±24.97, and 355.37±31.70; p<0.001). In the immediate postoperative period, the median lung ultrasound score was higher in Group H than that in Groups LR and HR (6 [5–7], 3 [3–5], and 3.5 [2.25–4.75]; p<0.001). The incidence of oxygen desaturation and oxygen requirements was higher in Group H during the postoperative period.Conclusion: The RM before extubation is beneficial in reducing atelectasis and postoperative pulmonary complications, irrespective of the FiO2 concentration used in older adults undergoing major abdominal surgeries.

In this editorial we comment on the article by Kalayarasan and co-workers published in the recent issue of the World Journal of Gastrointestinal Surgery . The authors present an interesting review on the use of indocyanine green fluorescence in different aspects of abdominal surgery. They also highlight future perspectives of the use of indocyanine green in mini-invasive surgery. Indocyanine green, used for fluorescence imaging, has been approved by the Food and Drug Administration and is safe for use in humans. It can be administered intravenously or intra-arterially. Since its advent, there have been several advancements in the applications of indocyanine green, especially in the surgical field, such as intraoperative mapping and biopsy of sentinel lymph node, measurement of hepatic function prior to resection, in neurosurgical cases to detect vascular anomalies, in cardiovascular cases for patency and assessment of vascular abnormalities, in predicting healing following amputations, in helping visualization of hepatobiliary anatomy and blood vessels, in reconstructive surgery, to assess flap viability and for the evaluation of tissue perfusion following major trauma and burns. For these reasons, the intraoperative use of indocyanine green has become common in a variety of surgical specialties and transplant surgery. Colorectal surgery has just lately begun to adopt this technique, particularly for perfusion visualization to prevent anastomotic leakage. The regular use of indocyanine green coupled with fluorescence angiography has recently been proposed as a feasible tool to help improve patient outcomes. Using the best available data, it has been shown that routine use of indocyanine green in colorectal surgery reduces the rates of anastomotic leak. The use of indocyanine green is proven to be safe, feasible, and effective in both elective and emergency scenarios. However, additional robust evidence from larger-scale, high-quality studies is essential before incorporating indocyanine green guided surgery into standard practice.

Published: March 2024

Gastric peroral endoscopic myotomy (G-POME) is an emerging minimally invasive endoscopic technique involving the establishment of a submucosal tunnel around the pyloric sphincter. In 2013, Khashab et al used G-POME for the first time in the treatment of gastroparesis with enhanced therapeutic efficacy, providing a new direction for the treatment of gastroparesis. With the recent and rapid development of G-POME therapy technology, progress has been made in the treatment of gastroparesis and other upper digestive tract diseases, such as congenital hypertrophic pyloric stenosis and gastric sleeve stricture, with G-POME. This article reviews the research progress and future prospects of G-POME for the treatment of upper digestive tract gastrointestinal diseases.

BACKGROUND

Radical surgery combined with systemic chemotherapy offers the possibility of long-term survival or even cure for patients with pancreatic ductal adenocarcinoma (PDAC), although tumor recurrence, especially locally, still inhibits the treatment efficacy. The TRIANGLE technique was introduced as an extended dissection procedure to improve the R0 resection rate of borderline resectable or locally advanced PDAC. However, there was a lack of studies concerning postoperative complications and long-term outcomes of this procedure on patients with resectable PDAC.

AIM

To compare the prognosis and postoperative morbidities between standard pancreaticoduodenectomy (PD) and the TRIANGLE technique for resectable PDAC.

METHODS

Patients with resectable PDAC eligible for PD from our hospital between June 2018 and December 2021 were enrolled in this retrospective cohort study. All the patients were divided into PDstandard and PDTRIANGLE groups according to the surgical procedure. Baseline characteristics, surgical data, and postoperative morbidities were recorded. All of the patients were followed up, and the date and location of tumor recurrence, and death were recorded. The Kaplan-Meier method and log-rank test were used for the survival analysis.

RESULTS

There were 93 patients included in the study and 37 underwent the TRIANGLE technique. Duration of operation was longer in the PDTRIANGLE group compared with the PDstandard group [440 (410-480) min vs 320 (265-427) min] (P = 0.001). Intraoperative blood loss [700 (500-1200) mL vs 500 (300-800) mL] (P = 0.009) and blood transfusion [975 (0-1250) mL vs 400 (0-800) mL] (P = 0.009) were higher in the PDTRIANGLE group. There was a higher incidence of surgical site infection (43.2% vs 12.5%) (P = 0.001) and postoperative diarrhea (54.1% vs 12.5%) (P = 0.001) in the PDTRIANGLE group. The rates of R0 resection and local recurrence, overall survival, and disease-free survival did not differ significantly between the two groups.

CONCLUSION

The TRIANGLE technique is safe, with acceptable postoperative morbidities compared with standardized PD, but it does not improve prognosis for patients with resectable PDAC.
