Authors: Susanna Susanna , Hasnah Hasnah  , Karina Shofiya Putri
Published: May 2023

Dieback disease caused by L. theobromae has destroyed nutmeg plantations in Aceh Selatan. Until now, effective control has not been found, while farmer continue to use pesticides that have a negative impact on the environment. Therefore, biological control is an alternative to environmentally friendly control that is being promoted. The purpose of this researth was to control dieback by inducing resistance using three spesies of Trichoderma (local isolates) from the Nutmeg. The three isolates were isolates of plant origin and the nutmeg seeds used are one year old. This researth used a randomized blok design with three species of Trichoderma (T. virens, T. asperellum, and T. harzianum), three doses (5, 10, 15 g), and three replicates.The variables observed were the incubation period, disease incidence, length of stem discoloration, height of the plant, and plant wet weight. Thr result showed that all species of Trichoderma tested were able to induce systemic resistance and promoted plant growth, by inhibiting the incubation period, disease incidence, length of discoloration, increasing height and weight of plant. The treatment of T. virens 10 g was the best treatment result compared to the others.

ABSTRACT

 

One of the causes of pest problems that dominate in cayenne pepper is the monoculture planting system. Monoculture cropping systems have a lower diversity of pests and natural enemies in the field compared to polycultures. imbalance in the ecosystem in a crop, causing insect pests to become more resistant and dominate. Utilizing flowering plants is one of the efforts to maintain the balance of the existing ecosystem in the cayenne pepper plantation. The purpose of this study was to determine the effect of flowering plant species on the population and diversity of pests and natural enemies of cayenne pepper, then find out what treatment is the most effective for reducing pest populations. This research was conducted from August to December 2021 on land located in Gebang Village, Southeastang District, Bondowoso. The research design used was a randomized block design (RAK) with several treatments including P0 (Control), P1 (Sesamum indicum), P2 (Sphagneticola trilobata), P3 (Turnera subulata) and P4 (Turnera ulmifolia). The observed variables were the population of pests and natural enemies, the diversity of pests and natural enemies. The results showed that several types of flowering plants had an influence on Arthropoda diversity in cayenne pepper plants with a moderate category, the population of pests and natural enemies showed significantly different results in several weeks. The most effective treatment that can reduce pests is P3 (Turnera subulata) treatment which can reduce the pest population of B. dorsalis and show the highest population of its natural enemy, Oxyopes.

In modern conditions of development, digital platforms in small and medium-sized businesses began to be widely used during the development of Industry-4.0 globalization. Modern studies define digital platforms as an electronic environment that includes a general set (list) of goods and services with a corresponding digital configuration. Examples of digital platforms are: digital music platform "Spotify" or "iTunes", digital movie platform "Netflix", etc. The article established that from the point of view of the economy, digital platforms are auxiliary electronic environments (markets) on which sellers and buyers buy and sell goods. And digital entrepreneurship is also considered as the process of creating a new Internet business. In the process of research, it was established that thanks to the spread of digital platforms, entrepreneurs have opportunities to stimulate innovation to create new products or services. In the framework of Industry 4.0, globalization and digitalization have created some benefits for participants based on digital platforms. First of all, through digital platforms, manufacturers can assess buyers and end consumers without going through intermediaries. Also, digital platforms allow sellers to display their products in virtual shopping centers through a website, and consumers can view product information at a time and place convenient for them. It has been proven that small and medium-sized enterprises are one of the main engines of the modern economy, which contribute to the development of the country's economy, the creation of income, employment and innovation in various fields. Small and medium-sized enterprises are the key to economic growth and market competition in most developed economies due to their flexibility and ability to innovate. According to the results of the conducted research, it is confirmed that the use of digital tools and platforms helps small and medium-sized businesses to determine the right direction for improving the efficiency of small and medium-sized enterprises within the framework of Industry 4.0 and digitalization trends. After all, the activity of small and medium-sized business enterprises directly affects the total GDP of the country. Thus, the subject of further research is the study of factors that can increase the productivity of small and medium-sized business enterprises, which is important in determining the directions of the future development of small and medium-sized business enterprises.

Perch selection of three species of kingfishers at the Pantanal of Brazil
Authors: Peinado L. C. , Ortega Z.
Published: May 2023

Selecting a suitable perch can offer many benefits for fish–eating birds such as kingfishers. However, factors affecting perch selection in these species remain poorly studied. We studied perch selection in three species of kingfishers inhabiting the Pantanal of Brazil during the dry season: Megaceryle torquata, Chloroceryle amazon, and Chloroceryle americana. First,we determined the habitat use of the three species. We then assessed the perches these kingfishers used based on four ecologically relevant traits: (1) artificial or natural, (2) perch height, (3) distance to the water, and (4) plant cover. We hypothesized that artificial perches could be more likely selected as they may offer better visibility to fish. We used a resource selection function (RSF), in a case/control design, solving it by model selection of six conditional logistic regression competing models. The probability of presence was independent of the artificial origin of a perch for the three species. It was also independent of the other studied variables, except for individuals of C. amazona, which selected higher perches. We conclude that artificial perches do not influence perch selection of the studied kingfishers, which may indicate that these artificial structures are not altering their behavioral choices.

Authors: DeBiasse Michele A. (Shelly) , Gardner Burt Kate , Qamar Zubaida
Published: May 2023

The Academy of Nutrition and Dietetics (the Academy) is a professional organization founded by and largely for white women. Black-identifying dietetics professionals currently make up only 2.6% of credentialed professionals, while Black-identifying residents comprise 13.4% of the US population. To understand participant opinions, beliefs, experiences, knowledge, and actions related to racial ethnic diversity and inclusion (REDI) in general and in dietetics specifically we conducted a 20-week intervention study, delivered over a social media platform (Facebook group). The content, developed prior to the intervention, was informed by the Trans-theoretical Model of Change and Critical Race Theory and was structured to provide educational content related to REDI. Participants completed baseline, and then a follow up survey after the 20-week intervention. Here we present baseline data from (n=30) Black-identifying participants of the main study. Participants were mostly young, female, Academy member RDNs with at least a Master’s degree. They voiced strong opinion that dietetics is neither diverse nor inclusive, and that the Academy should actively engage in efforts to enhance diversity in the profession. They believe that the Academy should focus on REDI and that it is important that white-identifying members engage in that work. Participants reported engaging in conversations and with media about race/privilege in their personal and professional lives, and that they had either experienced or witnessed microaggression while performing their jobs in dietetics. Results of this sub-study offer insight into the Black experience in dietetics as well as ways the Academy can improve diversity and inclusion within its organization and membership.
Firms Size and the Effects of Investment on Equity Value
Authors:   Korean Association Of Computers And Accounting, Bang Shin－Suk
Published: May 2023

The purpose of this study is to examine the relative influence of investment expenditure and equity value according to firm size. However, according to previous studies, there is a difference in management decision making and various management policies depending on the size of the company, and the response in the capital market also suggests that there is a difference in the size of the company. The larger the size of the firm and the higher the market dominance, the more likely it is to realize economies of scale, so it is clear that the market response to the investment of these large firms will be different from the market response to the investment of small firms. Therefore, this study focuses on the difference in the size of these companies and examines the relationship between investment and equity value by each size. In addition, it is divided into alternative investment and adaptive investment according to the attributes of investment, and it is intended to compare and examine how these investments affect equity value. Forecasts related to this study are expected to differ in the relationship between investment expenditure and equity value depending on the size of the company, and to differ depending on investment properties. In order to empirically analyze this, this study analyzed the large and small sized companies, and as a result of the analysis, there was a difference in the response of the market in both the large and small sized companies. In other words, investment expenditure, alternative investment, and adaptive investment of large companies showed positive effects on equity value, but small companies showed non－significant effects. The results of this study are expected to provide important implications for research on investment decisions and decision making.

Published: May 2023

This study analyzed the effect of financial ratio and corporate social responsibility(CSR) on corporate value for listed companies in China, respectively, and further analyzed whether CSR have additional moderating effects in the relationship between financial ratio and corporate value. The financial ratios used in this study were profitability(net return on equity capital) and growth potential(sales growth rate), and corporate value was measured using the Tobin－Q value. Whether the CSR activities of the listed company are evaluated and disclosed in RKS was used as a CSR measurement variable, and additional analysis was conducted using the CSR evaluation score as a measurement variable because the CSR score could affect corporate value. The sample used in this study consisted of 14,566 company－year samples for companies listed on the China Shanghai Stock Exchange and Shenzhen Stock Exchange A stock market for six years from 2013 to 2018. The analysis results of this study are summarized as follows. First, both the sales growth rate and the net return on equity capital showed a statistically significant positive relationship with corporate value. Second, the social responsibility activity variable also showed a significant positive relationship with corporate value. Third, it was found that the financial ratio and CSR interaction variables had statistically significant positive values. Fourth, an additional analysis of only companies with CSR evaluation scores showed that both the financial ratio and CSR have a significant positive effect on corporate value, respectively. However, both financial ratio and CSR interaction variables were not statistically significant, indicating that the CSR evaluation score did not have a moderating effect on the relationship between financial ratio and corporate value.

The experiment was conducted to examine the physical properties, pH, temperature, proximate composition, fibre fraction, energy content and mineral composition of ensiled rice milling waste (RMW) treated with urea and poultry litter in a completely randomized design. RMW was treated with of Urea and Poultry Litter (PL) and ensiled in in-vitro laboratory silos (946ml). The treatment combinations were; A (100%RMW), B (100%RMW+ Urea), C (80%RMW + 20%PL), and D (60%RMW + 40%PL). The treatments were ensiled for 21 days in triplicates. At the expiration of each ensiling period, samples were taken for analyses. The results for physical properties showed that most of the silages were adequately fermented with sweet aroma. The compounded silages were acidic 4.34 – 4.86 except treatments B and D which had pH of 7.96 and 7.91 respectively. The temperatures of the silages were significantly (P<0.05) different. Based on the physical properties, pH and temperature evaluated, most of the silages can be considered to be well prepared. The proximate composition of silages differ significantly (P<0.05), higher percentages in CF and Ash were recorded in Treatment A. Dry matter content was also significantly different (P<0.05) with treatment A having the highest DM (97.19%). The CP in treatment D (6.13%) proved superior. RMW and Urea mixtures resulted in silages with highest %NDF, %HEM and Energy. Lowest NDF, ADF, CEL and ADL values were obtained in treatment D. The nutritive quality of treatment D was proved to be higher and thus it is recommended for dry season ruminant feeding.

The study was carried out to evaluate the potentials of Afzelia africana seed (AAS) on growth performance and nutrient digestibility of rabbits. AAS were collected in New Bussa. The seeds were washed and air-dried before processing. They were divided into three portions. One portion was ground raw and two portions were separately toasted at a temperature of 400C for 30 minutes. The toasted seeds were milled for inclusion in the diets. One of the toasted portions was toasted for the second time after milling at 400C for 30 minutes. Four experimental diets were formulated. Diet 1 contained 0 % AASM while diets 2, 3 and 4 contained raw, toasted and re-toasted AASM at 20 % levels of inclusion. Twenty-four crossbred rabbits with initial weight of 650 g were used. The animals were divided into four treatments of six rabbits per treatment. Each treatment had triplicates of two animals housed in wire/wooden hutches. They were allocated to the four dietary treatments in a completely randomized design for twelve weeks feeding trial. Feed intake and weight gains were determined. At the end of the feeding trial, digestibility trial was conducted. Final weight, total weight gain, mean weight gain, total feed intake and feed conversion ratio were significantly (P<0.05) different between the treatments. Although animals on diet 1 showed superior weight gain, those on diet 4 performed better than animals on diets 2 and 3. It is thus concluded that re-toasted AASM can be used in the diet of rabbits.

Published: May 2023

About a third of teenagers experience an anxiety disorder, with steadily increasing numbers (McCarthy, 2019). LGBTQ+ students have a history of being a group without a voice because the dominant gender classification was a binary male or female model. They have seldom dared to express and identify their real selves. According to Lewis (2020), this form of oppression could make them feel unwelcome, overlooked, and unsafe, eventually creating tremendous anxiety. This qualitative research focused on understanding what creates an inclusive and safe learning environment for all students, including students who identify as LGBTQ+. Interviews were conducted with students, parents, and educators working with students who identified as LGBTQ+ in Marin County, California. The first finding identified how providing diverse opportunities in school contributed to an inclusive environment. These opportunities fall into several categories, including recognizing a diverse student body, honoring diverse characteristics and personality traits, and providing diverse institutional structures. Another major participant finding was that building relationships is central to LGBTQ+ students, which is demonstrated in the aspects of increasing the sense of being heard, having a relaxed learning and socializing environments, and building community norms together with choice. The third finding is a call for further transformation, and includes four major sub findings. The first argues for adopting a non-binary model for gender diverse students. The second calls for improved leadership, role modeling and curriculum revolution. The third addresses ongoing rejection and stigmatization, and the need for professional education and activities of support to provide the care needed. The last sub finding is a call for funding to endorse these diverse initiatives.
