Categorizing Natural Language-Based Customer Satisfaction: An Implementation Method Using Support Vector Machine and Long Short-Term Memory Neural Network
Analyzing natural language-based Customer Satisfaction (CS) is a tedious process. This issue is practically true if one is to manually categorize large datasets. Fortunately, the advent of supervised machine learning techniques has paved the way toward the design of efficient categorization systems used for CS. This paper presents the feasibility of designing a text categorization model using two popular and robust algorithms – the Support Vector Machine (SVM) and Long Short-Term Memory (LSTM) Neural Network, in order to automatically categorize complaints, suggestions, feedbacks, and commendations. The study found that, in terms of training accuracy, SVM has best rating of 98.63% while LSTM has best rating of 99.32%. Such results mean that both SVM and LSTM algorithms are at par with each other in terms of training accuracy, but SVM is significantly faster than LSTM by approximately 35.47s. The training performance results of both algorithms are attributed on the limitations of the dataset size, high-dimensionality of both English and Tagalog languages, and applicability of the feature engineering techniques used. Interestingly, based on the results of actual implementation, both algorithms are found to be 100% effective in accurately predicting the correct CS categories. Hence, the extent of preference between the two algorithms boils down on the available dataset and the skill in optimizing these algorithms through feature engineering techniques and in implementing them toward actual text categorization applications
DIVERSITY AND ABUNDANCE OF MITES IN A MANDARIN CITRUS ORCHARD IN WEST SUMATRA
Some of the most destructive pests in citrus orchards are spider mites. Monitoring prior applied pest control is a standard procedure for integrated pest management (IPM). The study aimed to survey and determine the distribution, abundance, and diversity of phytophagous, predatory, and detritivorous mites at different stages of development of arboreal plant parts, weeds and litter in the citrus orchard. A periodical sampling survey method was conducted on six growth stages of mandarin citrus, weeds and litter of the Indonesian Fruits Research Institute experimental field in Solok, West Sumatra in December 2003 to June 2004. All mites attached on each growth stage of citrus, weeds and litter were trapped and mounted on slide for identification purposes. Identification of the mites was conducted in the Acarology Laboratory, Department of Entomology, University of the Philippines at Los Banos in July-October 2004. The results showed that a very rich mite fauna of 130 species was found in the arboreal parts of citrus crops, weeds and litter below the canopy of the citrus orchard. Among the trophic groups, detritivorous mites were the most abundant, followed by the predators, phytophages, and those unknown feeding habit. Among the habitats, weeds harbored the most mite species followed by litter and arboreal parts of the citrus trees. The flush growth stage had the least diverse mite fauna with index diversity (H’) of 1.27, while the most diverse (H’ = 2.01) was found at fruit development phase II. Result of this research was useful in determining proper time for controlling phytophagous mites. Besides, the result also provides important information on potential predatory mites that can be used as biological control agents. Furthermore, the study implies the importance of maintaining cover crops of weeds and litter beneath the citrus trees as refuge and source of alternate prey for predators which suppressed populations of phytophagous mites
RESEARCH CAPABILITIES OF PUBLIC ELEMENTARY SCHOOL TEACHERS AND MANAGEMENT SUPPORT OF THE SCHOOLS DIVISION OF NUEVA VIZCAYA, PHILIPPINES
Purpose of the study: This study determined the research capabilities of public elementary teachers in the Schools Division of Nueva Vizcaya and also to determine the management support extended to them in terms of research support and research environment condition.
Methodology: This study employed the descriptive-correlational method. The descriptive method described the characteristics of the respondents, the level of research capabilities and dissemination, and management research support factors. Two hundred eighteen respondents were drawn from the population. A Stratified random sampling method was used to determine samples per stratum. The researchers observed research ethics and protocols during the gathering process. Descriptive-Inferential statistics were used to interpret the data.
Main Findings: The study found out that respondents who attained higher educational attainment and attended national training have improved research skills and are more knowledgeable in the research process and dissemination. The respondents are moderately capable in their research capabilities and research dissemination. The level of research capabilities was significantly correlated with educational attainment and training. Research support was inadequate; a favourable research environment was provided.
Applications of this study: The findings of the study provide data to the Department of Education to know the factors affecting the research capabilities of public school teachers. The DepEd school heads can come up with a workable plan to enhance research capabilities and manage their resources, policies, time, space, and personnel for maximum effect.
Novelty/Originality of this study: The fast trend in instructional technology and innovative approaches and teaching pedagogies, knowledge, and skills in the research of all academic professionals is essential. Conducting research becomes now mandatory in the educational institutions in the Philippines; thus, needs continuous assessment to produce a community of teacher-researchers
A gut-to-brain signal of fluid osmolarity controls thirst satiation.
Satiation is the process by which eating and drinking reduce appetite. For thirst, oropharyngeal cues have a critical role in driving satiation by reporting to the brain the volume of fluid that has been ingested1-12. By contrast, the mechanisms that relay the osmolarity of ingested fluids remain poorly understood. Here we show that the water and salt content of the gastrointestinal tract are precisely measured and then rapidly communicated to the brain to control drinking behaviour in mice. We demonstrate that this osmosensory signal is necessary and sufficient for satiation during normal drinking, involves the vagus nerve and is transmitted to key forebrain neurons that control thirst and vasopressin secretion. Using microendoscopic imaging, we show that individual neurons compute homeostatic need by integrating this gastrointestinal osmosensory information with oropharyngeal and blood-borne signals. These findings reveal how the fluid homeostasis system monitors the osmolarity of ingested fluids to dynamically control drinking behaviour
Beyond Covid-19: The Future of Festivals in Calabarzon, Philippines
Purpose: This study aims to determine or forecast the willingness of regular participants of festivals to attend or join events festivals in the post-COVID-19 scenario. Specifically, it aimed to 1.) identify the perceived future of festivals in the post-pandemic scenario and if people are still willing to participate in or join in any of the festival's events, and 2.) discuss the role of festivals in the post-pandemic scenario.
Â
Theoretical framework: The researchers employed the stakeholder theory technique to predict the future of the festival's events. A stakeholder is "any group or person who may impact or is affected by the attainment of the institution's objective," Freeman (1984). Freeman contends that a person or group is a stakeholder if it has a sincere interest in a particular component of the institution's operations and, as a result, either can influence the company's performance or has a stake in that performance. Particularly, in this study, the stakeholders are the participants, the businessmen, and the organizers of the festivals. Ultimately, the perception of the stakeholders may be used by festival organizers as a basis for holding festivals in the post-pandemic scenario.
Â
Design/methodology/approach: This study used a qualitative design using phenomenological approach based on the lived experiences of the participants with the festivals they have attended. Snowball sampling was used to choose 32 participants, commencing with the tourist local government official that had control over the festival events. The researchers utilized key informant interviews and focus group discussions on obtaining data, guided by a semi-structured questionnaire to allow the researchers to adjust questions according to the participant's willingness and manner of answering. For data clustering and theme identification, the researchers utilized a qualitative research tool (NVIVO) with license key: (N-L-Z-7-7) and used the analytical framework by Moustakas (1994), as covered by Creswell (2007). The researchers began by outlining the subject's or participant’s encounters concerning the festivals being examined. Next, they created collection of noteworthy remarks and organized these into more substantial units of information (i.e., units or themes).
Â
Findings: As a result, every participant is eager to engage, be present, or take part in their respective festivals again, once the COVID-19 restrictions are removed, but some have a few reservations.
Â
Implications for research, everyday life, and society: In the Philippines, the COVID-19 restrictions were lifted in 2023. This is also a time for the local economy to recover. The series of lockdowns heavily hampered the local economy due to the pandemic. The local governments may use festivals to help small, medium, and microenterprises recover from the losses they took during the pandemic, and festivals. can kick start the local economy. Festival organizers may utilize the findings of this research as a foundation.
Â
Originality/value: All the data gathered in this research was at the peak of lockdowns and cases of COVID-19 in the Philippines. This made it very difficult for the researchers to collect data, thus resulting in an integration of in-person interactions, key informant interviews and online focus group discussions. It was a time when mass gatherings were hard to imagine, let alone the celebration of festivals uncertain. Nevertheless, the result was surprising since all the participants were still willing to join or attend festivals
Effect of Adding Different Levels of Duckweed (Lemna minor Linn.) in the Diet on Live Body Weight, Hematological Traits and Production Cost of Free-range Chickens, Gallus domesticus Linn. (Black Austrolorp x Barred Playmouth Rock)
The present study was conducted at Bataan Peninsula State University Abucay Campus to evaluate the growth performance and hematological profile of Gallus domesticus Linn. (Black Austrolorp x Barred Playmouth Rock) chicken fed formulated diets of varying inclusions of lesser duckweed (Lemna minor Linn.). Three formulated treatments diets of homogenous crude protein level were prepared: 0% duckweed (control), 10% duckweed, and 15% duckweed inclusion. Five chickens (average weight 202.5 g) per replicate were reared in a single factorial experiment and the feeding trial was carried-out for three months. Chicken fed diet containing 15% duckweed meal treatment had significantly (P < 0.05) higher body weight (1,425.88 ± 55.24 g) compared to chicken fed normal diet (1,223.48 ± 174.47 g). Mean cost to produce a kilogram of meat was significantly cheaper in the treated diets (F = 4.82; P < 0.05). Mean values of hematological variables were not significantly different among treatments
Budesonide Enhances Agonist-Induced Bronchodilation in Human Small Airways by Increasing cAMP Production in Airway Smooth Muscle
The non-genomic mechanisms by which glucocorticoids modulate β2 agonist-induced-bronchodilation remain elusive. Our studies aimed to elucidate mechanisms mediating the beneficial effects of glucocorticoids on agonist-induced bronchodilation. Utilizing human precision cut lung slices (hPCLS), we measured bronchodilation to formoterol, prostaglandin E2 (PGE2), cholera toxin (CTX) or forskolin in the presence and absence of budesonide. Using cultured human airway smooth muscle (HASM), intracellular cAMP was measured in live cells following exposure to formoterol, PGE2, or forskolin in the presence or absence of budesonide. We showed that simultaneous budesonide administration amplified formoterol-induced bronchodilation and attenuated agonist-induced phosphorylation of myosin light chain, a necessary signaling event mediating force generation. In parallel studies, cAMP levels were augmented by simultaneous exposure of HASM cells to formoterol and budesonide. Budesonide, fluticasone and prednisone alone rapidly increased cAMP levels, but steroids alone had little effect on bronchodilation in hPCLS. Bronchodilation induced by PGE2, CTX or forskolin was also augmented by simultaneous exposure to budesonide in hPCLS. Furthermore, HASM cells expressed membrane-bound glucocorticoid receptors that failed to translocate with glucocorticoid stimulation, and that potentially mediated the rapid effects of steroids on β2 agonist-induced bronchodilation. Knockdown of glucocorticoid receptor α had little effect on budesonide-induced and steroid-dependent augmentation of formoterol-induced cAMP generation in HASM. Collectively, these studies suggest that glucocorticoids amplify cAMP-dependent bronchodilation by directly increasing cAMP levels. These studies identify a molecular mechanism by which the combination of glucocorticoids and β2 agonists may augment bronchodilation in diseases such as asthma or chronic obstructive pulmonary disease
