The Impact of Academic Emotions on Language Learning in the University Context: a Narrative Review Wathuge, PC Emotions affect learning in general and language learning (LL) in particular since they contain useful information that guides human cognition, behaviour and motivation. As such, emotions experienced in an academic setting affect the learner in a variety of ways. University students are frequently affected by emotions as a result of the difficulty in adjusting. This condition is observed as having impacted on LL, particularly on English, which has now become a very decisive factor in academic learning and achievement in Sri Lanka. The study aimed at identifying the wide array of emotions that are experienced in academic settings, their properties, the theoretical underpinnings, sources, functions and the impact of positive academic emotions (PAE) and negative academic emotions (NAE) on LL. It was also expected to identify the research trends in emotions and LL over the decades. This article is composed in the form a narrative review for which 30 studies on emotions and learning during the past 16 years were explored. A narrative inductive method was utilized to identify patterns across gathered data and to condense varied secondary data gathered from extensive reading into a summary format. The information found were analysed thematically in relation to the research questions. The findings suggest that, it is very difficult to set clear cut rules to prove positive emotions (PE) foster and negative emotions (NE) hinder LL for they serve different useful purposes. The impact of emotions on LL should therefore be further analyzed theoretically and investigated empirically pertaining to different contexts. There also exists a need to empirically test the existing limited theories on emotion to figure out the range of their validity within diverse contexts. The major implication derived from the study is that, language teaching in Sri Lankan universities, where English is taught as a second language (L2), is quite a mindful undertaking which should be planned and carried out with great care bearing in mind the strong relationship between emotions and learning.

Determining the Statistical Process Control Limits for Uncertified Sri Lanka Standard (SLS) Boxes of Matches in Sri Lankan Market Perera, RASA; Mudannayaka, KWGMNB; Rupasinghe, RAGS Quality control limits through Statistical quality control charts are used to control the quality of the process in product manufacturing. It can be used to determine whether the manufacturing process is operating according to the desired quality standards. Manufacturing boxes of matches should be in appropriate quality as it is considered the safety consuming item. This paper addresses the main objective of determining the statistical quality control limits for uncertified Sri Lanka Standards (SLS), boxes of matches manufactures in Sri Lanka”. Sub research objective is “to determine whether SLS Uncertified Boxes of matches are Really safety related to its production process.”. 1135 sample units of match sticks were used for the study using 25 samples for the study. Primary data were gathered using direct observation method from uncertified Sri Lanka Standards box of matches manufacturers regarding the considered quality characteristics in both variables and attributes in product. Eight quality dimensions such as the number of matches in a box, ignition and burning, afterglow, length of splint and match head, bending strength, were the considered quality characteristic of the boxes of matches. These quality characteristics were taken from SLS recommendations. Statistical Quality control equations, Statistical quality charts were used to analyse the data. Lower control and upper control levels of the characteristic of the SLS uncertified match boxes are as follows. Length of Splint 30.7 mm -34.8mm, length of the head 3.3mm -3.5mm, Burning time 13.8sec – 17.8 sec, Bending strength 35.1sec-40.7 sec, Afterglow 1.46 sec- 2sec, safety 0 -12.6, adherence 203 0-4.89, No of match sticks in the box 44-46 sticks. Generated quality control limits prevailed within SLS requirements except the quality dimensions, the Length of Splint and the Burning time. They highlight that these boxes of matches which do not have SLS are unsafe due to the uncontrolled production process based on SLS. Thus, the Sri Lankan manufacturers should draw their attention to produce full quality productions with a high priority to safety.

A Study on the Factors Influencing the Use of E-commerce by Customers in Colombo With Respect to B2C Market Lokuhettige, SL; Ranwala, LU This study explores the factors influencing the use of e-commerce by the customers in Colombo district with regard to the B2C market. The conceptual framework was designed based on the Theory of Planned Behaviour (TPB) and 24 potentially influential factors were explored throughout the study. Primary data were collected by means of a questionnaire given in internet based and printed formats where the respondents were received from both users and non-users of online purchasing in the Colombo district of Sri Lanka. 354 valid questionnaires were used in the analysis and the Cronbach’s Alpha was 0.719 in the reliability test. A proper and well explained descriptive analysis of the variables followed by the KMO and Bartlett's test, Hypothesis testing, Factor analysis and an advanced model fitting was carried out. Analysis revealed that there is a very positive opinion towards online purchasing and people do have the willingness towards it. In view of the above and the model developed, it was found that attitudinal factors have a profound effect while subjective norm and perceived behavioural control shows a superficial effect on the online purchasing intention. Based on the inferences from research findings, recommendations and strategic and managerial suggestions were also made.

The Impact of Parental Involvement on Students’ Attitude and Performance in Science in Batticaloa Educational Zone, Sri Lanka Elankumaran, C; Arulmoly, C This study was carried out to find the impact of parental involvement on student’s attitude and their performance in science subject. A sample survey design was adopted for this study. The study was directed at the population of senior secondary students in the Batticaloa educational zone, in the Batticaloa district of Eastern Province in Sri Lanka. The sample was 400 students who studied in grade 12 and 13 science and mathematics streams and offering the physics and chemistry subjects. Ten 1AB schools from this research area were selected for the study. The 1 AB schools in Kalmunai zone were stratified into urban and semi-urban schools. 40 male and female students from the grade 12 and 13 were randomly selected with (late adolescent. To make the total of 400 respondents, 40 were selected from all 10 schools to constitute the sample for this study. The schools consist of 4 semi- urban and 6 urban schools was selected for this study. The students’ questionnaire, consists of section A which is made up of 24 questions, measuring the attitude of the students while the section B contain 18 questions for measuring the parental involvement (home influences) items. They were Likert scale item type questions, in which respondents choose from 5point scores such as strongly, agree to strongly disagree. Thirdly, information concerning the individual performance (in percentages) of students was obtained from their continuous assessment records of the school subjects concerning (physics and chemistry. Three null hypotheses were postulated and tested at 0.05 level of significance to the impact of parental involvement on student’s attitude and their performance in the science subject. Data collected on the study were analysed using inferential statistics which include; student analysis of variance (ANOVA) and Pearson product Moment correlation coefficient. The result of the study showed that there is a significant relationship between students’ attitude towards performance of physics and chemistry and their parental involvement (p=0.012 and 0.026 respectively). And there is a significant relationship between performance of physics and chemistry and their parental 233 involvement (p=0.019 and 0.031 respectively). The correlation of coefficient between attitude and performance (physics and chemistry) are positively and significant (r=0.66, p=0.013 and r=0.53 and p=0.019 respectively). The phenomena observed were discussed in the light of prevailing conditions in most of the developing countries. Conclusively, home influence can be a tool to enhance school learning.
