A case-control study in NAT2 gene polymorphism studies in patients diagnosed with acute myeloid leukemia
Authors: Farasani Abdullah
Published: September 2023

Introduction: Acute myeloid leukemia (AML) is a clinically defined heterogeneous disease whose pathophysiology is currently unknown. The association of NAT2 acetylation profiles with human cancer risks, particularly with AML, was investigated in molecular epidemiological studies. Additionally, the NAT2 gene was carried out with acute lymphoid leukemia and other cancers. Aim: In this case-control study, C481T (rs1799929) and G857A (rs1799931) polymorphism studies were investigated in diagnosed AML patients in the Saudi population. Methods: This case-control study included 100 AML patients and 100 control subjects recruited in Saudi Arabia. The C481T and G857A polymorphisms were genotyped using specific primers and restriction enzymes. Statistical analysis was performed on the AML patients and controls using chi-square tests, genotyping, and allele frequencies (odds ratios, 95% of confidence intervals, and P-values). Results: Hardy Weinberg Equilibrium was determined to be both within and outside of the G857A and C481T polymorphisms. The allele and genotyping frequencies in AML and control subjects were analyzed, and the results corroborated the unfavorable connection with C481T (CC vs CT+TT; OR-1.12; (95% CIs: 0.64–1.96); P=0.67 and T vs C; OR-0.89; (95% CIs: 0.59–1.35) and P=0.60) and G857A polymorphisms (GG vs GA+AA; OR-1.50; (95% CIs: 0.83–2.71); P=0.17 and A vs G; OR-0.71; (95%CIs: 0.43–1.19) and P=0.19) in the NAT2 gene. Conclusion: The study results revealed a negative correlation as well as a protective factor for AML with the C481T and G857A polymorphisms in the NAT2 gene.
Vitamin D supplementation improves the therapeutic effect of mometasone on allergic rhinitis
Authors: Guo Minfei
Published: September 2023

This study aimed to investigate the efficacy and safety of vitamin D supplementation in the treatment of allergic rhinitis (AR) using mometasone. A total of 140 patients with moderate and severe AR treated at our hospital between January 2017 and August 2020 were recruited as subjects for this study. The patients were randomly divided into control and experimental groups, with 70 patients in each group. Mometasone nasal spray was used in both groups, and vitamin D was administered to the experimental group for four weeks. The total nasal symptom scores (TNSS) and rhinoconjunctivitis quality of life questionnaire (RQLQ) were used to assess the efficacy of treatment. T lymphocyte subsets (CD3+, CD4+ and CD8+) and serum anti-inflammatory and proinflammatory cytokines such as interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) were analyzed. The incidence of adverse reactions was recorded. Serum vitamin D levels were lower in patients with AR. After 4 weeks of treatment, total TNSS scores, T lymphocyte subsets (CD3+, CD4+), CD4+/CD8+ ratio, TNF-α, and total RQLQ scores were significantly reduced compared to the initial testing (P<0.05) in the two groups; CD8+, IFN-γ, and IL-10 levels as well as serum vitamin D were significantly increased compared to the initial test (P<0.05). The improvement in these parameters in the experimental group was significantly greater than that in the control group (P<0.05), except for sneezing and eye symptoms in the TNSS and RQLQ scores. It was concluded that vitamin D supplementation improves the therapeutic effect of mometasone nasal spray on AR and is thus recommended as an adjuvant therapy for moderate and severe AR.

Improvements in agriculture has been focusing on innovations to improve the efficiency of the activity by making the traditional production structure currently in use more flexible and by making the necessary technological changes for farmers with large areas and the necessary machinery and equipment. Farms with significant arable land are able to offset the effects of changes affecting efficiency and profitability. The decisive sector of agriculture in Hungary is crop production, therefore its performance is largely determined by the annual output of the crop sector and the volatility in prices. From the farm data, we calculated farm-level results that support the need for machinery modernisation efforts, as precision tools and improvements already started in maize production can be applied fruitfully even in the light of the increasing frequency of negative climatic effects. During the development of silage maize cultivation technology, the achievements of precision farming were applied. Differentiated nutrient replenishment and sowing operations were used, in addition to the fact that harvesting was also documented. We set ourselves the goal of analyzing the management data of the study period between 2019-2022 in order to reveal the nature of the changes that occurred in terms of production value, production cost, and income, as well as the components that shape them. The presented values ​​are average values ​​of such conditions which are also suitable for crop-level conclusions. At the same time, they can be used to identify sector-level challenges and trends.

Published: September 2023

In implementing the family planning program (KB), there are several methods, but the most interesting is the study of sterilization methods. The MUI has issued a fatwa on sterilization 4 times, of which the fourth fatwa is that sterilization is haram except for the last fatwa which is haram with exceptions or conditions. The fatwa was criticized by Masjfuk Zuhdi who argued that the MUI fatwa needed to be reviewed. This research revolves around the focus of the study, what is Masjfuk Zuhdi's opinion about sterilization in the family planning program and what is the analysis of Masjfuk Zuhdi's opinion about sterilization in the family planning program. This research is a library research. The results of this research show that although the rules of fiqh can be used as a postulate as a factor in changing the new 'illat from the law of sterilization which was originally haram to become permissible due to evidence of recanalization, the success of recanalization in reconnecting the cut channels. has not been proven to be real. Consequently, his opinion about the unlawfulness of sterilization has not been proven in the field.

Published: September 2023

3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) lyase deficiency is a rare autosomal recessive mitochondrial disease characterised by recurrent life-threatening metabolic crises generally presenting in neonates or infancy during catabolic stress triggered by prolonged fasting or intercurrent illness. Acute decompensations with lethargy, vomiting, hypoketotic hypoglycemia and metabolic acidosis may evolve into Reye-like syndrome if untreated, with acute liver failure, hyperammonemic encephalopathy, dilated cardiomyopathy, and death in 20% of cases. Long-term health complications include psychomotor retardation, white matter abnormalities, epilepsy, hepatic steatosis, pancreatitis, cardiomyopathy, and arrythmia. The mitochondrial enzyme catalyses the cleavage of HMG-CoA to acetyl-CoA and acetoacetate, the common final step of ketogenesis and leucine degradation, resulting in diagnostic urinary organic acid pattern (elevated 3-hydroxy-3-methylglutaric, 3-methylgutaconic, 3-methylglutaric, and 3-hydroxyisovaleric acids) with the absence of ketonuria, when deficient. Therapeutic interventions include dietary protein or leucine and fat restriction, carnitine supplementation, avoidance of fasting, and use of carbohydrate-based high caloric intake when unwell. We describe the clinical course and diagnostic work-up in two affected siblings, with the proband presenting with severe neonatal onset disease with metabolic acidosis, non-ketotic hypoglycaemia, hyperammonemia and white matter changes on brain MRI. High-risk screening for a younger sibling led to pre-emptive management with good outcomes. Sodium D, L-3-hydroxybutyrate (S-DL-3OHB) was used in both siblings as an adjunct therapy to prevent cerebral dysfunction and cardiomyopathy, with the rationale that decreased ketogenesis in this disorder may impact the major energy source for the brain and heart during starvation. S-DL-3OHB therapy is a well-tolerated and effective therapeutic option for this disorder.
Evaluation of Virtual Prenatal Care for Obstetric Care Delivery During the COVID-19 Pandemic: A Mixed Method Research Study Using the Consolidated Framework in Implementation Research
Authors: Delgado Arlin , Reid Chinyere N. , Hale Emma , Marshall Jennifer , Fryer Kimberly
Published: September 2023

Background and Objective:

Coronavirus 2 (SARS-CoV-2), a novel respiratory virus, rapidly spread, and placed patients at increased risk for short and potentially long-standing medical illnesses. The pandemic necessitated the rapid implementation of virtual prenatal care via telemedicine in obstetrics to maintain social distancing measures. The aim of this study was to assess and understand the patient perspectives of the rapidly implemented virtual prenatal care via a telemedicine model during the Coronavirus disease 2019 (COVID-19) pandemic utilizing the Consolidated Framework in Implementation Research (CFIR).

Methods:

Following the implementation of virtual prenatal care in March 2020, pregnant patients at a large urban clinic in the southeastern United States completed a 19-question anonymous survey that included open and closed-ended questions on their experience receiving virtual prenatal care via telemedicine or in-person prenatal care from May to December 2020. The survey and mixed-methods data analysis was guided by the CFIR framework.

Results:

A total of 59 patients completed the survey. One-third (31%, n=18) of the patients found virtual prenatal care to be an acceptable alternative model, and half (53%, n=31) found it acceptable only during a pandemic, preferring to return to in-person visits. Qualitative analysis found that some patients were deterred by limited in-person examinations and uncertainty with the virtual platform, while others appreciated the reduced need for transportation, childcare, and time spent.

Conclusion and Global Health Implications:

Most patients found virtual prenatal care to be easy to access and an acceptable alternative during the pandemic; however, most would prefer to return to in-person prenatal care visits. Future comparative research studies should examine how, among others, virtual prenatal care versus in-person prenatal care impacts specific maternal and fetal outcomes.

Published: September 2023

For the construction of a Glass Earth a 3D geological entity model needs to be loaded into a Digital Earth visualization engine to visualize the expressions of geological entities. Space expressed by a 3D geological entity model is formed by a research area that extends vertically to a certain depth range in a projected coordinate system. When a 3D geological entity model is loaded into Digital Earth, the model-bounding box is combined with the model’s central point to perform the transformation, which causes the boundaries of adjacent models to deviate from each other to various degrees. Moreover, gaps and overlaps form at the top and bottom of the models, respectively. In this study, based on analyses of elevation naturalization correction and Gaussian projection deformation characteristics, bounding box–based free-form deformation was used to realize the model transformation in the process of loading a complex 3D geological entity model. By establishing a parametric model and mapping its relationship to the object to be deformed, free-form deformation was used based on deformation error correction. In this way, deviations between 3D geological entity models loaded into Digital Earth can be reduced. Using practical project cases, 3D geological entity models located at the margin of a zone six degrees wide in longitude and their central regions were comparatively analyzed. The results show that the free-form deformation used in this study can effectively reduce deviation problems in models.

Gray leaf mold, caused by the ascomycete fungus Passalora fulva (Cooke) U. Braun & Crous (anamorph: Cladosporium fulvum), is one of the most common fungal diseases affecting tomato cultivation in Ecuador. This study aimed to isolate monosporic cultures from tomato leaves exhibiting signs of gray leaf mold and characterize them culturally and morphologically. The investigation was conducted in the Tungurahua province, where samples were collected from eight municipalities. Eighty monosporic isolates of C. fulvum were obtained from leaves affected by gray mold. The fungal isolates exhibited olive-green colonies on the obverse and black on the reverse, with raised surfaces, felty texture, and irregular shape. The majority of isolates displayed lobed edges. No pigmentation or exudates were observed in the colonies. Mycelial growth was measured at 7 and 14 days, with average velocities of 0.93 mm/day and 1.23 mm/day, respectively. The average hyphal diameter was 5.41 µm, while conidiophores had an average size of 33.01 µm, and conidia measured 6 µm in length and 5 µm in width. These characteristics correspond to the reported morphological descriptions of C. fulvum.

Induction of sprouting is widely used in Solanum tuberosum tubers to reduce the sprout growth time. The main objective of this article was to evaluate the effect of different concentrations of gibberellic acid (GA3), ethanol, and hydrogen cyanamide (Dormex) on the budding of buds, length, and number of sprouts in Solanum tuberosum L. var. Cecilia tubers. Previously disinfected tubers were immersed in three sprouting inducers at different concentrations and placed in two peat-based substrates (TS1 and TS2). The tubers were submerged for 72 hours for gibberellic acid, while hydrogen cyanamide (Dormex) and ethanol were immersed for 15 minutes. The number and length of sprouts per tuber were evaluated. A completely randomized block design was used in each experiment. At 21 days of using gibberellic acid (GA3) (5 mg.L-1, 9 mg.L-1, 7 mg.L-1, and 3 mg.L-1), ethanol (0.5%, 0.7%, 0.3%, 0.9%, and 0.1%), and hydrogen cyanamide (Dormex) (3%, 4%, 2%, 0.5%, and 1%), the length of the sprouts in S. tuberosum var. Cecilia tubers increased, but it did not affect the number of projections. The types of substrates (TS1 and TS4) did not influence the length or number of sprouts in the budding of Cecilia potato tubers. Based on the results of this study, it was concluded that GA3, ethanol, and Dormex promoted the budding of buds in S. tuberosum var. Cecilia tubers.

Aquaculture is an essential economic activity worldwide, supplying the requirements of various nations. The larval stage is one of the most critical periods during the production cycle in aquaculture. To contribute to amplifying the knowledge related to viable methods to enhance this activity, the present study investigated the effects of prebiotic fructooligosaccharide (FOS) and the synthetic peptide GHRP-6 in the growth of fish, as well as its repercussions on a series of digestive enzyme activities and immune response parameters. Tilapias (Oreochromis niloticus) larvae were divided into three groups: group 1, fed with pre-formulated feed; group 2, fed with feed + FOS; group 3, fed with feed + GHRP-6. We measured the gain in size and weight at 72 and 87 days after starting the diets. At the end of treatment, we continue feeding the animals with a standard diet using the pre-formulated feed. We measured immune system parameters and digestive enzyme activities on larvae homogenate, focusing on lysozyme and antiprotease activity and α-amylase, trypsin and esterase activity, respectively. Results show a significant increment in size and weight in those fish fed with feed + FOS. Meanwhile, the primary enzyme activity was detected in those fish fed with feed + GHRP-6. On rough terms, both food combinations stimulated the immune system.

Our study suggests that FOS and GHRP-6 could be desirable additives to incorporate into the tilapia larvae feeding and increase production efficiency.

This study aimed to evaluate cut and hydroponic oats' production and nutritional quality (A. elatius) under different planting densities and harvest times. A 3x3x3 factorial experimental design was used, which consisted of 3 treatments: T1 (cut oats), T2 (hydroponic oats with nutrient solution) and T3 (oats without nutrient solution). Each treatment had three replicates. The study factors were the sowing densities of cut oats (0.150 kg/m2, 0.200 kg/m2, 0.250 kg/m2), harvest time (45, 60, 75 days) and the sowing densities of hydroponic forage with and without solution were: 1.5 kg/m2, 3.0 kg/m2, 4.5 kg/m2, harvest times (8, 12, 16 days). Hydroponic cultivation conditions favored morphological development, agricultural yield, and plant height, which reduced cutting times and increased harvested forage volumes and forage weight. The combination of sowing density of 0.15 kg/m2 and harvesting every 75 days gave the best results. Hydroponic oat production with and without nutrient solution increased forage weight, protein percentage, fat and fiber content. Likewise, the economic analysis determined that hydroponic oats with nutritive solution recovered 0.44 cents for each dollar invested, the treatment that reached the highest profitability. Based on the results obtained, it was concluded that the production of hydroponic green forage under the effect of planting densities and harvest time influenced the production rates. It is an efficient alternative for small forage producers in the Ecuadorian highlands.

Previously disinfected tuber shoots were sown in a culture medium composed of MS + 20 g.L⁻¹ sucrose + 7 g.L⁻¹ agar and exposed to different illumination conditions. The number of nodes, the number of leaves, the number of shoots, plant height, percentage of establishment and percentage of contamination were determined. At 30 days, total fluorescent white light and 12 h natural light + 12 h darkness showed a greater plant height, while the lighting conditions showed no effect on the number of nodes, number of leaves, number of shoots per plant, percentage of establishment and percentage of contamination. Based on the results of the present work, it was concluded that both total white fluorescent light and 12 h natural light + 12 h darkness favored in vitro establishment.

Can Environmental Labels Fight the Cattle Industry’s Impact on the Environment?
Authors: Parida Tuhina , Sahoo Lipika
Published: September 2023

The environmental impact of the cattle industry is severe. When considering land-use effects, its emissions per capita are comparable to the impact of energy usage (Ranganathan et al., 2016). Cattle farming produces 20 times higher emissions per gram of protein than plant protein (Waite et al., 2022). Previous research (such as Camilleri. et al., 2018) has indicated that people underestimate the carbon footprint of food items, especially red meat. There have been a few studies on the effectiveness of environmental labels, however, the results are mixed. This paper sheds light on the impact of environmental labels containing information on water consumption, land use, and the carbon footprint of meat vs. plant-based meat on consumers’ buying behavior. We create a survey and distribute it across three platforms—Amazon Mechanical Turk, Prolific, and students and staff at a high school in Massachusetts, USA. We receive a total of 260 responses. The results indicate that participants exposed to the environmental labels choose an average of between 0.61 and 1.1 more plant-based meat patty packages out of five packages than those not exposed to the labels. This emphasizes the effectiveness of environmental labels in influencing consumer choices towards more sustainable options.
Emotional Contagion Ability Scale: Compilation and empirical validity for Chinese college students
Authors: Xu Erjia , Hu Ping
Published: September 2023

The aim of our research was to develop a reliable and valid questionnaire to assess trait emotional contagion ability in Chinese college students. In Study 1 we generated a preliminary questionnaire by modifying previously established questionnaires and eliminating items assessing emotional
response. The final version consisted of 12 items categorized into four dimensions, and it demonstrated high reliability and validity. Study 2 was designed to examine the empirical validity of the questionnaire in a laboratory setting. Results revealed that trait emotional contagion ability
was significantly associated with muscle activity and level of state emotional contagion in the laboratory experiment, indicating that the Emotional Contagion Ability Scale is a valid tool for assessing emotional contagion ability and can be utilized in laboratory-based emotional contagion
research among college students.
Financially constrained consumer responses toward attribute- and goalframed advertisements
Authors: Wang Haijun , Liu Jinggang , Wang Hui
Published: September 2023

The global outbreak of the COVID-19 epidemic has placed considerable financial constraints on people???s lives, which may have changed their attitude toward advertising. This study explored the differential persuasiveness of attribute- versus goal-framed advertising on consumers with
various financial constraints. The results of two studies (ns = 93 and 79, respectively) showed that consumers with higher (vs. lower) financial constraints were more responsive to attribute-framed (vs. goal-framed) advertisements for a fictional airline, and that this relationship
was mediated by processing fluency. This research contributes to the literature on message framing and offers guidance for marketers looking to improve their targeting through developing more tailored advertisements.
Emotional awareness and adolescent relational aggression: The moderating effect of Machiavellianism
Authors: Zhao SiQi , Guo Hong , Wang Hong , Ta Lin , An LianChao
Published: September 2023

Despite previous research highlighting the impact of relational aggression on interpersonal relationships, few studies have examined the occurrence of this phenomenon during adolescence. To address this gap we conducted a crosssectional study of 702 Chinese adolescents to examine the
association between emotional awareness and relational aggression, and the moderating effect of Machiavellianism. Our results revealed that there was a significant correlation between emotional awareness and relational aggression, and that Machiavellianism moderated this relationship. Specifically,
we found that emotional awareness was a stronger negative predictor of relational aggression at low versus high levels of Machiavellianism. These findings provide new insight into potential strategies for reducing adolescent relational aggression.
Effect of cognitive attitude and affective attitude on formative assessment practice: Intention as a mediator
Authors: Xiang Xiaoqing , Yum Sichang , Lian Rong
Published: September 2023

Despite the significance of formative assessment in the classroom, limited empirical research has been conducted on this topic in Mainland China. We investigated the relationship between formative assessment practice and both cognitive attitude and affective attitude, and explored whether
the intention to implement a formative assessment would mediate this relationship. Participants were 504 Chinese primary school teachers. In this study formative assessment practice had two aspects: instructional adjustment and feedback practice. The results showed that the relationship between
affective attitude and formative assessment practice was partially mediated by intention and that the relationship between cognitive attitude and formative assessment practice was fully mediated by intention. This study highlights the importance of affective attitude in practicing formative
assessment and has implications for teacher training.
Campus exclusion and deviant behaviors of Chinese adolescents: Fear of missing out as a mediator
Authors: Liu Yi Hui , Su Chun Jing
Published: September 2023

We investigated the mediating role of fear of missing out in the relationship between campus exclusion and the deviant behaviors of Chinese adolescents. Deviant behaviors were measured using items included in the China Education Panel Survey, and the survey we conducted with
831 Chinese adolescents also included the Adolescent Campus Exclusion Questionnaire and the Chinese version of the Fear of Missing Out Scale. We found that campus exclusion, fear of missing out, and deviant behaviors were significantly and positively associated with one another. Fear of missing
out played a mediating role in the relationship between campus exclusion and deviant behaviors. To some extent, our findings reveal the mechanism of adolescents??? deviant behaviors and have implications for teachers and parents in intervening in and preventing deviant behaviors in this group.
Social support and mathematics anxiety: The mediating role of learning engagement
Authors: Wang Rui , Ramel Mohd Rustam Mohd
Published: September 2023

Mathematics anxiety is a common emotional condition among students, but few studies have explored the mediating mechanisms that could account for the impact of social support on this anxiety. To address this gap, we examined the mechanism of the impact of social support on mathematics
anxiety with a sample of 1,191 high school students in Inner Mongolia by looking at the role of learning engagement as a mediator. The students completed the Multidimensional Scale of Perceived Social Support, the Student Engagement in School Orientation Questionnaire, and the Mathematics
Anxiety Questionnaire for Children. The results showed that learning engagement mediated the relationship between social support and mathematics anxiety. These findings provide theoretical support for the use of interventions related to learning engagement to reduce the mathematics anxiety
of high school students.
The trickle-down effect of leader mindfulness on employee creative deviance behavior: A moderated mediation model
Authors: Chen Jiaxian , Peng Wei , Han Lijuan
Published: September 2023

Applying social learning theory and the trickle-down effect, in this study we built a cross-level research model to explore how high-level leader mindfulness stimulates employee creative deviance behavior via the mediating effect of middle-level leader mindfulness. Using data obtained
from 345 employees and 81 of their leaders in manufacturing research and development enterprises in China, our results showed that high-level leader mindfulness had a significantly positive effect on middle-level leader mindfulness. Middle-level leader mindfulness, in turn, positively affected
employee creative deviance behavior and mediated the relationship between high-level leader mindfulness and employee creative deviance behavior. Further, leader???member exchange positively moderated the relationship between high-level leader mindfulness and middle-level leader mindfulness,
and also moderated the indirect effect of high-level leader mindfulness on employee creative deviance through middlelevel leader mindfulness. The study findings will help organizations to understand how leader mindfulness affects employees??? creative deviance behavior and also provide practical
enlightenment for enterprise innovation management.

Published: September 2023

Our purpose was to explore the relationship between the physical activity and social adaptation of junior high school students, as well as the mediating role of socioemotional competence and self-esteem. We surveyed 980 junior high school students using four scales: the Physical Activity
Rating Scale, the Social Adaptability Diagnostic Scale, the Social-Emotional Ability Scale, and the SelfEsteem Scale. Results showed that physical activity had a significant positive correlationwithsocialadaptation.Further,socioemotionalcompetenceandselfesteem had both independent mediating
and chain mediating roles in the relationship between physical activity and social adaptation. The results have revealed the mechanism of the relationship between physical activity and social adaptation and provide a preliminary basis for study of the causal relationships between these variables.
Our results also provide a theoretical basis for intervention and promotion of social adaptation.

Authors: Wang Haibin , Zhu Leiye , Cao Ying , Han Fen , Yao Qiong
Published: September 2023

Emotional awareness is regarded as a prerequisite for emotional intelligence and regulation. We conducted a series of five studies involving 2,045 teachers to generate a questionnaire containing 21 items with six factors focusing on teachers??? emotional awareness in three dimensions:
themselves, their students, and interpersonal. The self dimension included two factors of teaching emotions and nonteaching emotions, the student dimension included two factors of facial expression and body language, and the interpersonal dimension included two factors of teacher???student
interaction and student???student interaction. The questionnaire demonstrated sound internal consistency reliability, test???retest reliability, and criterion-related validity. Thus, the Emotional Awareness Questionnaire for Teachers in China can be used to evaluate the emotional awareness
of primary and middle school teachers in China.

Published: September 2023

We used the theory of social dominance to explore the mediating influence and boundary conditions according to which subordinates??? creativity affects supervisor undermining. Through a two-stage survey of 223 employees and their paired supervisors, we verified the mediating effect
of supervisors??? perceived status threat on the relationship between subordinates??? creativity and supervisor undermining. Supervisors??? status concern moderated the relationship between subordinates??? creativity and supervisors??? perceived status threat. Specifically, the positive relationship
between subordinates??? creativity and supervisors??? perceived status threat was stronger when the level of supervisors??? status concern was high. We aimed to deepen understanding of the factors that influence supervisor undermining. Additionally, we introduced perceived status threat as
a mediating variable, which enhances understanding of the mechanism behind the unjust treatment of star employees. This highlights the importance of companies continuing to improve the management and professional skills of their supervisors, and fostering an organizational culture that is
equal and free, in order to cultivate and retain highly creative talents
