Impulsive Buying, Post-purchase Regret, and Credit Card

Impulsive buying is an unplanned purchase and is coloured by a strong urge that is difficult to resist buying suddenly. It is usually triggered by external conditions when dealing with products, accompanied by the arising of pleasant and passionate feelings with the consequences of anxiety, regret, and sometimes debt as well. It is suspected that it has something to do with the use of credit cards. This study was conducted in 249 early adult women aged between 18 and 22 years. The research method used is a quantitative survey with convenient sampling. A linear regression test is used for data analysis. The results showed a relationship between the three variables, in a positive direction. The higher the tendency to use credit cards, the higher the impulsive buying, and the higher the post-purchase regret that results. The practical implication of this research is the importance of discount as a promotional tool, in addition to the product's appearance and store atmosphere. Credit cards are one of the functional strategies that offer practicality, convenience, and safety for consumers. Although the use of credit cards facilitates the payment process, consumers should be wiser in using them, given the possibility of increased impulsive buying and post-purchase regret that can arise.
Phylogeny and temporal diversification of mosquitoes (Diptera: Culicidae) with an emphasis on the Neotropical fauna

Understanding phylogenetic relationships within the family Culicidae informs mosquito evolution and may have public health implications as this family includes numerous species of medical and veterinary importance. We investigated the mitochondrial genomes of 102 mosquitoes, including six newly sequenced species, representing 21 genera with an emphasis on the Neotropical region. We estimated divergence times based on sequence data and three fossil calibration points, using Bayesian relaxed clock methods. Bayesian and maximum‐likelihood phylogenetic analyses based on the DNA sequences of 13 PCGs of the 102 species provided robust support for the monophyly of the subfamily Anophelinae and the tribes Aedini, Culicini, Mansoniini and Sabethini. Despite the current genera of Anophelinae being consistently recovered as monophyletic, relationships among them proved to be quite variable depending on the method used (concatenated or partitioned) and the number of taxa sampled. Molecular divergence time estimates revealed that the two mosquito subfamilies, Anophelinae and Culicinae, diverged in the early Jurassic (approximately 197.5 Mya). However, most major lineages of these groups arose after the Cretaceous, coincident with the emergence of angiosperms and the expansion of mammals and birds. The diversification and worldwide distribution of Culicidae may also be determined in part by geographic isolation as a result of continental drift during the Cretaceous.
Student Thinking Levels in Solving Open-Ended Geometric-Function Problem by Algebraic Representation Approach

The mathematical problem mostly has been involved in the measurement of student ability according to study objectives and data needs. In this study, geometric-function problem has been used to data collection, analyzed problem type, and students thinking levels based on their completion. The sample of this study was three student high school in a science programme in the region of West Jakarta who selected purposively. Based on data analyzed, the result was found that students view the problem as the task constructed algebraic function formula. The completion and solution that have been shown by students, categorized the problem in open-ended type. The finding of mathematical thinking levels analysis there was a different complexity of thinking process between students because the number of concepts applicate. According to van Hiele theory, student’s geometry thinking levels was on abstraction level minimally, and the problem is not relevant for deduction thinking level criterion. For the analysis result about algebraic thinking levels, by the structure of the observed learning outcome (SOLO) taxonomy, students at the levels between relational and extended abstract. Students in these levels was a student high ability so it is appropriate with the background of the sample selected.
The Impact of Stakeholder Involvement in Evaluation System Design: Lessons from the Zimbabwe Education Sector Experiences

The design of a performance evaluation system should ideally be inclusive and participatory to enhance stakeholders’ buy-in, acceptance and ownership of the system, whilst at the same time, ensure relevance and sustainability of the process. This paper examines the design process of the teacher evaluation system in one education district of Zimbabwe. The study intended to establish the extent of teacher involvement in the design of the evaluation system and to determine the relationship between the design process and effectiveness of the evaluation system. The study used the convergent mixed method design. A quantitative sample of 292 teachers and a qualitative sample of 12 educators, namely teachers, heads of departments and school heads drawn from 10 secondary schools participated in the study. Quantitative data were analysed using SPSS version 26 and descriptive and inferential statistics were conducted. Atlas ti. 8 was used to analyse the qualitative data. The study established that the design process was exclusive and non-participatory, which led to lack of ownership and buy-in by the teachers. Based on these findings, it was concluded that the design process was faulty and negatively impacted the effectiveness of the teacher performance evaluation system. The study recommends that policy formulation should be inclusive and pilot tested to allow input of the users before full scale implementation.

Three-dimensional thermohydrodynamic analysis of the effects of textured main bearing on lubricant density and viscosity in internal combustion engines

This paper is focused on the effects of the textured surface along with lubricant feed pressure and temperature variation to calculate the lubrication characteristics (viscosity and density) of the main bearings in internal combustion engines. In a three-dimensional numerical analysis simulation, a thermohydrodynamic model was developed, which considered the thermal effects of the fluid–solid interface components. In the analysis, the viscosity–temperature equation was used at different lubricant feed pressures and temperatures. By using color image segmentation methods, the density and viscosity contour on the two rotating walls (shaft and bearing wall) in the cavitation regions were quantitatively and qualitatively compared. The textured surface and lubricant feed pressure had significant effects on reducing the cavitation region over the shaft and bearing surface. Compared with the untextured bearing, the presence of texture over the bearing surface in the same temperature and pressure conditions increased the amount of total heat transfer to the lubricant fluid in the range of the maximum value of 73% and minimum value of 11%. Promoting the average heat transfer coefficient was a factor in reducing thermal stresses and high-temperature points in the rigid parts of the bearing system.
Dental and Oral Health Status of Elementary School Children in Central Lampung

Introduction: Dental caries and gingivitis are the most prevalent oral health problems in Indonesian elementary school children. Predictors that are significantly associated with dental caries and gingivitis in children are the parents’ socioeconomic status and children’s oral health behavior. Terbanggi Besar district is the largest area and population in Lampung Province. The lack of updated dental and oral health data needs to be refined to address oral health disparities and achieve improvements. Objectives: This study aimed to assess the dental and oral health status of grade V and VI elementary school children in Terbanggi Besar district, Central Lampung. Method: This cross-sectional study elected 410 students from 5 public elementary schools using convenience sampling. Sociodemographic and oral health behavior data were retrieved from a self-administered questionnaire. In addition, a clinical examination consisted of the Decayed, Missing, and Filled Teeth (DMFT) index, the Gingival Index (GI), and the Simplified Oral Hygiene Index (OHIS). The Mann-Whitney statistical test was used to analyze the differences in dental caries severity and gingival status between selected variables. Results: Dental caries was present in 75.6% of children, while gingivitis was present in 52% of children. The mean DMFT score was significantly higher in children with poor oral hygiene (2.80 + 2.67, p = 0.001). The mean GI score was significantly higher in children aged 12 years old or above (0.37 + 0.48, p = 0.025) and in those that had unemployed fathers (0.25 + 0.29, p = 0.030) and poor oral hygiene (0.31 + 0.40, p = 0.000). Conclusion: Improving dental and oral health promotion with regard to elementary school children is highly recommended. The dental and oral health status of grade V and VI elementary school children in Terbanggi Besar district in Central Lampung was found to be moderate, with a high prevalence of dental caries.
EFFECT OF PLANT GROWTH REGULATORS ON FRUIT SPLINTING IN THOMPSON NAVEL ORANGE

Fruit splitting is one of main problems extensively observed in citrus-growing area located in the northern parts of Iran. In order to investigate the effect of 2,4-D and GA3 on incidence of fruit splitting in Thompson navel orange, an experiment, as a factorial arrangement in a randomized complete block design (RCBD) with three replications, was carried out in two consecutive years of 2016 and 2017. The main factors of this experiment included timing of spray at different growth stages (full bloom, petal fall, and June drop), 2, 4-D (0, 10, 20 mg L–1), and GA3 (0, 50, and 100 mg L –1). In the end of experiment, the characteristics including fruit length, fruit diameter, rind thickness, cellulase and polygalacturonase activities, total soluble solid, percentage of split fruit, and fruit yield were measured. Results showed that using 2, 4-D and GA3 not only decreased the rate of fruit splitting but also increased fruit yield as compared to controls. The highest fruit length, fruit diameter, rind thickness, total soluble solid and the lowest activities of cellulase and polygalacturonase were obtained using 100 mg L–1 GA3 and 20 mg L –1 2, 4 D during the full bloom. In general, the results revealed that using 2, 4-D and GA3 during the full bloom increased fruit yield while reduced fruit splitting and maintained the qualitative characteristics of Thompson navel orange.
Determinants of adoption of Deutsche Gesellschaft Für Internationale Zusammenarbeit (GIZ)-sponsored technologies among cassava farmers in Ogun State, Nigeria

Abstract Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) provides advisory services to cassava growers in Ogun State in order to bring about sustainable improvements in the livelihoods of participants as well as contributing to the economic development of the State. This study assessed the determinants of adoption of GIZ-sponsored technologies among cassava farmers. A total of 336 farmers (168 participants and 168 non-participants) were randomly selected from the 14 Local Government Areas where GIZ operated. Questionnaire was used to obtain primary data. Data was analysed using frequency counts, percentages, Logistic regression and test. Results showed that all (100.0%) of the participants had formal education and belonged to a farmers’ association. The average farm size for participants was 1.64 hectares. The average period of participation in GIZ’s service and number of training received by the farmers were 3 years and 11, respectively. Majority of the participants (98.8%) cultivated TME 419 and local cassava varieties, respectively. Logistic regression revealed technology cost (ß = 0.457), triability of technology (ß = 0.493), information accessibility (ß = −0.464), good relationship between GIZ’s agents and farmers (ß = 1.018) and government policy (ß = 0.493) were the determinants (p < 0.01) of participants’ involvement in GIZ’s service. It was concluded that GIZ service had positive effect. The study therefore recommends complete information on the nature, associated risks and the benefits derivable from the sponsored technologies. Also, government-friendly and GIZ-friendly policies by both the GIZ and government for the benefit of the farmers’ increased productivity is recommended.
Effective Method for Diagnosing Continuous Welded Track Condition Based on Experimental Research

The correct operation of the continuous welded track requires diagnosing its condition and preparation of track metrics requiring measurements of displacements of rail under operation. This is required as there are additional thermal stresses in the rails with values depending on the temperature changes of the rails. Therefore, the climatic conditions are important. This paper presents the original effective analytical method for diagnosing the condition of continuous welded track based on experimental research. The method allows for an appropriate repair or maintenance recommendation. In the experimental research, the authors considered track diagnostic conditions for two conditions: track under load and track without load. This paper presents empirical formulas for calculating rail temperature and longitudinal force based on ambient temperature, developed from long-term measurements. The formulas were developed for a track located on a straight section—both for a rail loaded and unloaded with a passing train under the following conditions: 60E1 rail, not on an engineering structure, conventional surface, wooden sleepers and very high train traffic load. The obtained results in the value of the correlation coefficient R2 ≥ 0.995 attest to very high accuracy of the calculations performed with the method proposed by the authors.
Research on Performance Evaluation and Improvement of Ifraz-2 Water Treatment Plant

Study of performance of water treatment plant (WTP) is essential to be assessed with all aspects and considerations including physical, chemical and bacteriological so as to determine its efficiency and to produce quality water to the consumer. Performance of any WTP is a crucial parameter to be evaluated to understand its operation, working, and efficiency. The present study aimed to evaluate the performance of Ifraz 2 WTP units, and to discover the problems of the efficiency in the units with providing appropriate solutions. Water samples were collected for six months from raw water, after clarification, after filtration, and storage tank. Turbidity removal efficiency for each unit and the whole WTP were calculated and presented. Results revealed that there is a wide variation of the raw water turbidity values which ranged from 51.8 NTU to 1978 NTU. Average removal efficiencies for the sedimentation unit, filtration unit, and the entire Ifraz 2 WTP were 92.25%, 64.99% and 97.54%, respectively. The efficiency of coagulation and flocculation processes are fluctuated due to the absence of optimum dosage of coagulant. In the filtration process, due to the little depth of filter bed, this makes the filtration process in low quality. For improving the process of filtration, an adequate adding of filter media is very necessary to improve filter efficiency. After disinfection and storage, the turbidity values of the treated water were increased in half of the samples due to availability of solids in the storage tank. A great part of solids removed after coagulation-flocculation and sedimentation tanks.
11B, 29Si and 27Al nuclear magnetic resonance studies of Na2O-Al2O3-B2O3-SiO2 glasses

11 B NMR, 29 Si and 27 Al magic angle spinning nuclear magnetic resonance techniques have been used to investigate the structure of glasses having the composition (40-x) Na 2 O, xAl 2 O 3 , 30B 2 O 3 , 30SiO 2 , where x ranges between 0 and 25 mol%. The results show that Al 2 O 3 preferentially associates itself with Na 2 O to form AlO 4 tetrahedra. The N 4 value of boron increases with the decrease of Al 2 O 3 and reaches a maximum, N 4(max) , at a mol% ratio ((Na 2 O)-(Al 2 O 3 )])(B 2 O 3 )=1
Psychometric evaluation of the Clinical Outcome in Routine Evaluation – General Population: Czech version

Objectives. This study aimed to assess psychometric properties, such as reliability, construct validity, and cut-off scores, for the Czech version of the Clinical Outcome in Routine Evaluation – General Population (GP-CORE) questionnaire, a tool usable for repeated measurement of psychological distress within routine clinical settings. Participants and setting. Two general populations and one clinical sample were used with N values of 420, 394, and 345, respectively. Hypotheses. One of the competing theoretical factor solutions will demonstrate the best fit. Statistical analysis. To examine the factor structure of the GP-CORE, a confirmatory multidimensional item response theory analysis (graded response model) was employed. Results. The best fitting model was a bifactor solution representing one content domain of overall distress and two item wording domains (positively and negatively worded items). Clinical cut-off scores were determined to be 1.85 (men) and 1.90 (women). Study limitations. The GP-CORE can be used as an unidimensional measure of overall distress, but users have to be aware of the influence of positive vs. negative item wording on the responses.
A Case Study of the Management of the Private Shelter for Unmarried Pregnant Adolescents

In Malaysia, one of the most worrying issues for the community, especially parents is the case of unmarried pregnant among adolescents. However, few parents and members of the community are truly sensitive to the threat of this social problem. Various efforts are being made by the government and non-government agencies to help these adolescents to reduce the problem. One of them is to create temporary shelters to guide and help the adolescents to move forward with their lives towards a more positive path. Nevertheless, these efforts can either have a positive or negative impact on the adolescents involved if the shelters are not properly managed. This qualitative study was conducted to explore aspects of management in a shelter set up specifically for unmarried pregnant adolescents. The results of the interviews with the shelter operator were transcribed fully before being analyzed thematically. The results of the study found that the nature of wanting to help and high perseverance had prompted the operator to set up a shelter specifically for unmarried pregnant adolescents. The shelter was found to gain strong social support. Among the support provided is from individuals or groups which include free academic teaching, food supply, daily necessities, finance for utilities, in addition to the creation of a comfortable physical environment. The operator also used social networks such as close friends to help manage the residents at the shelter. In addition, social media was also utilized by the operator so that many individuals provide assistance to maintain the management of the shelter. This study contributes to the management of shelter for adolescent girls especially unmarried pregnant adolescents.

The result shows that all types with only 4 reasons for code switching were found in this novel types of code switching which is inter-sentential switching is the most dominant because Alvi looks more comfortable when using words, clauses and phrases in one sentence to convey motivational messages and from the result of the reason of code switching talking about a particular topic is dominant because Alvi Syahrin feels free and more comfortable to express his emotional feelings in a language that is not his everyday language.
Assessment of four plant extracts as maize seed protectants against Sitophilus zeamais and Prostephanus truncatus in Ghana

Abstract Sitophilus zeamais and Prostephanus truncatus can cause weight loss of about 20 to 90% of untreated stored maize seeds. This study assesses four plants (Lantana camara, Moringa oleifera, Citrus sinensis and Hyptis suaveolens) extracts as seed maize protectants against the two insects in Ghana. The study was laid out in a CRD with three replications. Dried powders (5 and 10% w/w) and aqueous extracts (0.05 and 0.1 g/mL) of the botanicals were evaluated for their insecticidal activity with untreated control and Actellic included as checks. Oviposition and survivorship of insects decreased in grains treated with plant extracts. The phytochemical analysis revealed that compounds such as alkaloids, saponins, tannins and phenolic, steroids, flavonoids, anthraquinones, phlobatannins, cardiac glycosides and terpenoids were recorded in all four plant extracts. These compounds may have caused lower progeny emergence, inhibitory effect, repellent action and antifeedant effect to S. zeamais and P. truncatus in grains treated with the botanicals. Maize seeds treated with botanicals after 10 weeks in cribs recorded a reduction in the percentage of seeds damaged and weight loss caused by the two insects compared to the untreated seeds. The study proposes that the botanicals tested, especially H. suaveolens have the potential to enhance quality seed production thereby boosting growth in the seed industry. The botanicals are recommended for use by seed producers and farmers to control P. truncatus and S. zeamais in stored maize seeds.
