Why do upper secondary school students study chemistry – and why they do not?
Authors: Matti Vesterinen Veli- , Aksela Maija , Rantaniitty Toni
Published: March 2020

This study investigated the Finnish upper secondary school students’ opinions on the rationale of chemistry education and their reasons for choosing or not choosing advanced courses in chemistry. In first phase of the research 49 pre-service chemistry teacher students answered open questions about their opinions about the rationale of chemistry education as well as reasons for choosing advanced courses in chemistry in upper secondary school. The same students then interviewed 44 upper secondary students about their opinions on the topic. The survey used for the second phase of the study was based on the content analysis of the answers of chemistry teacher students and the transcriptions of the interviews of upper secondary school students. Four categories of rationales were found in the first phase of the study: (i) everyday life and health, (ii) environmental issues, (iii) general knowledge, and (iv) further studies and working life. Based on the data from the survey (N = 137), further studies and working life related reasons for teaching chemistry were considered most important. The reasons for choosing advanced courses in chemistry were divided in four categories: (i) interest, (ii) self-efficacy, (iii) utility value for university admission, further studies and working life, (iv) influence of parents, peers and teacher. Results indicate that interest in chemistry and utility value for university admission and further studies were the most important reasons for choosing advanced courses in chemistry. Boys and students with good grades in chemistry emphasized self-efficacy significantly more than the others. Girls emphasized utility value for university admission and further studies more than the boys. Influence of parents, peers and teacher was in average considered the least important category of reasons. The main reasons for not choosing advanced courses in chemistry were being more interested in other subjects and not needing chemistry for university admissions. To improve the number of people choosing advanced courses in chemistry, there is a need to improve interest in chemistry – especially as part of general knowledge of every citizen.
The Kitchen is a Laboratory: Experimental Science Activities Based on Food and Cooking
Authors: Mata Paulina
Published: March 2020

Since 2001, a group of Portuguese scientists has been using experiments with food and cooking to attract the interest of the public, and particularly young people, in science and scientific activities. These science dissemination activities, entitled A Cozinha é um Laboratório (The Kitchen is a Laboratory) have been received with great interest and very positive feedback by the general public, as well as by schools in all levels of education. Subsequently, this approach was also used by the Portuguese team of the Pollen: Seed Cities for Science project to promote inquiry-based science education in primary schools and engage families and the community in this process. This paper presents the activities conducted as part of these initiatives, which have already resulted in two books.
Early Mathematical Performance in Finnish Kindergarten and Grade One
Authors: Mononen Riikka , Aunio Pirjo
Published: March 2020

The present study assessed Finnish kindergarten (N = 177, Mage = 76.4 months, SD = 3.7 months) and grade one (N = 178, Mage = 87.2 months, SD = 3.7 months) children’s mathematical skills in the beginning of the school year. The mathematical skills were assessed once using researcher-developed paper-pencil tests. The variance analysis (ANOVA) was used to study the effects of age and gender on performance level. Boys and girls performed similarly in both samples, but age effects were found in the kindergarten and first grade; older children performed higher than younger ones. The older children may have had more opportunities to practise and get acquainted with mathematical issues, as the age difference between the youngest and the oldest child in the classroom can be up to one year. Children performing at or below the 25th percentile in both samples showed significantly weaker performance in several mathematical skills (i.e., number word sequences, enumeration, and addition and subtraction), compared to other performance groups. On the other hand, many children already understood in the beginning of the school year much of what is considered in mathematics curriculum and materials in their forthcoming school year in the kindergarten or the first grade.

The introduction was in the form of drama and guided the audience to the mathematical problems. After the introduction, a mathematical problem was solved in groups. After that the audience had the opportunity to explore the tent and games and problems inside of it. At the end, the audience pondered and solved a mathematical problem together.
Virtual Laboratory Environments in Chemistry Education
Authors: Telenius Marko
Published: March 2020

Various virtual laboratory environments have been developed during recent years, but upper-secondary school chemistry education has been missing a clear need for using them. The current reform of the upper secondary-school frame curriculum and the matriculation examination require upper secondary schools to increase the use of information and communication technologies. Virtual laboratory environments are ideally suited for this as they are affordable, interactive, free from the restraints of classroom space and time, as well as able to visualize difficult concepts in concrete ways. Simulations and virtual laboratories can be utilized to diversify the type of questions used in exams. Several virtual laboratory environments are available for comprehensive and upper secondary schools for free, but most of them cannot be utilized in classroom education without modifying them to suit the objectives of the lesson. It is the responsibility of the teacher to figure out how to use them to support learning.

Using open problems and cooperative methods in mathematics education
Authors: Ambrus András , Barczi-Veres Krisztina
Published: March 2020

Mathematics education is very country specific. Roughly speaking we can differentiate between two main styles in teaching mathematics: either the focus is on the students or the focus is on mathematics as a science. Hungarian mathematics teaching belongs to the second style. What can a teacher do in such tradition, are there chances to change the traditional boundaries? In our article we report about a teaching experience concentrating on the role of the teacher when changing the one-sided classroom teaching and also presenting students’ points of view in the changed teaching environment. Two aspects are taken into consideration in connection with mathematical problem solving: open problems and cooperative teaching.
Rethinking heuristics – characterizations and vignettes
Authors: Rott Benjamin
Published: March 2020

The concept of “heuristics” or “heuristic strategies” is central to (mathematical) problem solving and related research; however, there is no generally accepted definition of this term. Trying to clarify the concept might help avoiding misunderstandings and difficulties in dealing with studies that use different terms meaning the same concepts or that use the same terms meaning different concepts. Therefore, the research presented in this paper aims at a clarification of the term “heuristics” and suggestions for the use of it in future research. Building on previous work from last year’s ProMath conference, the consequences of using different characterizations of “heuristics” on vignettes (= short, completed scenes) of problem solving attempts are investigated. The conceptualization of “heuristics” has a significant influence on the types and numbers of perceived heuristics, which in turn affects empirical studies that identify and analyze heuristic strategies.
Motivation, self-image and developmental tasks influence students’ science-related career choice
Authors: Bertels Nina , Bolte Claus
Published: March 2020

We examined in which way chemistry lessons influence students´ intended career choice. Based on different theoretical approaches we are interested in answering the following question: Are the variables motivational learning environment, developmental tasks, self-to-prototype matching and self-concept connected to the career choice? For this purpose we developed a questionnaire which includes the variables motivational learning environment, self-concept, self-image and prototypes and developmental tasks. The questionnaire was given to students of German schools (Hauptschule) and trainees of the chemical industry. A regression analysis showed that the variables partly influence the choice of career.

Published: March 2020

Experiences shows that the knowledge of species among teacher students has decreased the last twenty years, and recent research from different parts of the world shows the same: The knowledge of species is decreasing. As an introduction to their science teacher education 39 students followed a course over seven weeks, where they learned more about plant and animal species in three different biotopes: forest, mountain and freshwater. The students replied to a questionnaire five weeks after the course. Both the three days field course and making their own collection of different plants and animals had great positive impact on the students learning of species. The students expressed that the practical work with plants and animals has increased their interest in science, will have positive impact on their work as science teachers and has increased their pleasure to be out in nature. The author ask for a discussion about species knowledge, biodiversity and field work in teacher education.
Teachers' experience of the introduction of student-centered pedagogies that promote lifelong learning and enthusiasm for chemistry and science
Authors: Farrugia Josette
Published: March 2020

This paper looks at the first steps taken by a group of Maltese teachers participating in the EU funded FP7 project aimed at promoting inquiry-based learning (IBL) in Mathematics and Science classrooms across Europe, PRIMAS, by providing long-term professional development (PD) to teachers during the introduction and implementation of IBL in an examination-oriented culture. Data were obtained through teachers’ reflective journals and interviews. Difficulties encountered and ways of overcoming challenges are presented. The main difficulties encountered may be classified as systemic difficulties; barriers due to teachers’ personal beliefs and attitudes; and student-related difficulties. Peer support, support of school authorities, and long-term continued PD are needed to help teachers move away from traditional teaching and implement IBL strategies.
Contextual, relevant and practical chemistry teaching at upper secondary school level textbooks in Finland
Authors: Ikävalko Veli-Matti , Aksela Maija
Published: March 2020

Contextual teaching approaches can motivate students, make chemistry learning more relevant and affect the students’ career choices later in life. This article presents the needs analysis section of a design research project. This needs analysis focused on the instructions for experimental tasks (N=160) found in Finnish upper secondary school textbooks and the STS (Science-Technology-Society) and everyday chemistry content in these instructions. It was found that the studied content can be divided into three levels: (II) context-based experiment instructions, (I) indirect contextual references and (0) no context. Over one third of the experiment instructions (37.5%) did not contain any context whatsoever. The content that did have a context mostly dealt with household chemistry related to everyday phenomena such as food and foodstuffs. The second most common themes in the instructions were: environment and nature and industry, technology and production. Most of the instructions were “recipe-like” and on the first level of Gilbert’s context model. In terms of relevance, most of the studied instructions focused on the individual level. In the future, experiment instructions should be developed to be more relevant at school level.
Linking macro and micro through element cycle: Desing research approach for introdutory chemistry course for 6-7 grades
Authors: Vysotskaya, Elena , Khrebtova Svetlana , Rekhtman Iya
Published: March 2020

To provide a solid understanding of chemistry at early stages of learning, any introductory course strives to link macro phenomena and their micro models in students’ thinking through some practical work with substances and related modeling at micro level; however, the transition to elements and atoms does not get adequate consideration. Our goal is to design a teaching strategy that reveals the essence of the notion of chemical element at both levels of its representation. We assume that (1) connections between the macro and the micro can be realized if we allow students to plan the experiments, and (2) the necessary context in which the concept of chemical element really works is a problem of preparation of a certain substance from other chemicals. Upon these principles, we have developed a local instructional theory that has then been tested and revised during three long-term macro-cycles of our design research experiment in 6-7 grades. We build on the Guided Discovery Approach to teach students how to distinguish and interpret simple physical and chemical changes through the substance-based particle model. In our course, students compose and explore copper and iron cycles of transformations, model composition of particles of the substances involved, revise interpretations of the experiments, investigate displacement reactions, acids, bases, etc. without explicit references to the concept of atoms. Along this way, students realize and master the idea that elements are conserved in reactions and every element gives rise to a cycle. Atoms then emerge as units of elements. The principal advantage of this approach is the appearance of meaningful questions that the subsequent chemistry course will answer. Students acknowledge that models are revisable as needed by the experiments. Such an introduction makes the subject of chemistry much more meaningful for students and eliminates many obstacles to successful learning.
The student-curated exhibition - A new approach to getting in touch with science
Authors: Kampschulte Lorenz , Parchmann Ilka
Published: March 2020

Exhibitions provide a great variety of opportunities for shedding light on a scientific topic. By visiting an exhibition, and even more so by curating an exhibition, students gain great insights into scientific topics. Developing an exhibition offers students multiple ways of engaging with a topic, and presents a multifaceted learning environment, in which skills believed to be highly relevant for individuals’ development into active, well-educated citizens can be developed. These skills support individuals in their private and working life, as well as enabling them to participate in a global society – with some of them (such as project management) being rarely addressed at school at all. To empower teachers to unfold this potential and create professional-like exhibitions within the tight time and budget frame of today’s school life, a simple exhibition framework (EXPOneer) is presented in this article. Its design will be used in the EU-funded project IRRESISTIBLE. Using IKEA shelves, the system allows students to build their own professional-like exhibitions at school based on available knowledge and everyday resources, without distinctive craftsmanship or special tools. The incorporation of student-curated exhibitions (SCEs) into school practice will also be discussed, based on examples of current exhibition projects. After briefly sketching the theoretical background in the first part of this article, the second part aims to enable teachers, as well as other people working with students, to start their own professional-like exhibition project.

Published: March 2020

TEMI, Teaching Enquiry with Mysteries Incorporated, is an EU-funded FP7 Science in Society project running from 2013 to 2016. The project aims to encourage science teachers to develop an understanding of inquiry-based learning as well as developing an understanding of the benefits of utilising such approaches in one’s classroom. Drawing on the 5E learning cycle, TEMI aims to engage pupils in core scientific concepts through the integration of mysteries and discrepant events in science lessons. This current discussion paper explores the approaches taken by the UL project team, one of the partners in the project, to bring about change in Irish second-level science teaching, as part of the TEMI project. In particular, it focuses on the unique aspect of this institution’s approach, which is the involvement of pre-service science teachers (PSST’s) in the project. The role of PSSTs in the project is explored under three main headings: “TEMI and the PSST as researcher”, “TEMI and professional learning communities” and “TEMI and PSST’s collaboration with co-operating teachers”. The paper concludes with a discussion on the benefits of involving PSSTs in the TEMI project.
IBSE in chemistry education - Testing students' skills and teacher training
Authors: Čtrnáctová Hana , Čtrnáctová Lenka , Šmejkal Petr
Published: March 2020

Inquiry Based Science Education (IBSE) as a new kind of education has been introduced into both the individual countries and the EU as a whole as an appropriate method for improvement on the current unsatisfying state of science education. Recently, new curriculum documents started to take effect in Czech Republic; these documents emphasize acquiring key competences and support the implementation of new strategies of teaching and learning. Many suggestions for IBSE education were also created as a part of national and international projects. For this reason, our article will focus mainly on the preparedness of pupils/students and their teachers for this new teaching method as a further condition of the application of IBSE into schools. In the first part of the article, we will list methods, procedures and results of a research that aimed to determine whether the pupils/students have enough skills to use the inquiry based method of teaching. In the second part of the article, we will start by focusing on the determination of teacher preparedness for IBSE and then on the preparation and realization of the IBSE training system for in-service and pre-service teachers in Czech Republic. This training system is based on the identification of a scientific “mystery” and active work of the teachers connected with their experience of inquiry and discovery. In the third part of the article, we will talk about the TEMI project which creates training programs for science teachers using IBSE and in which our country participates right now.
Nature of metacognition in a dynamic geometry environment
Authors: Kuzle Ana
Published: March 2020

This case study examined the metacognitive processes of a preservice teacher when solving a nonroutine geometry problem in a dynamic geometry environment. The main purpose of the study was to uncover and investigate patterns of metacognitive processes and to understand what circumstances, situations, and interactions in a dynamic geometry environment promoted metacognitive behaviors. An adaptation of Schoenfeld’s (1981) model of episodes and executive decisions in mathematics problem solving, and the theory of instrumentation (Rabardel, 2001) was used to identify patterns of metacognitive processes in a dynamic geometry environment. During different phases of problem solving the participant engaged in different metacognitive behaviors whereas the dynamic geometry software supported strategies that are available and/or not available on paper and pen. The effectiveness of solution paths was dependent on the presence of managerial decisions, and well-orchestrated usage of different resources, both knowledge and technology. However, the results of the study call to question to which extent engagement in metacognitive behaviors is necessarily desirable or productive.

In November 2014 we had a wonderful possibility to organize a seminar International Seminar on Mathematical Learning Difficulties with our international colleagues in the field of mathematical learning difficulties. One of the main aims was to provide open lectures for the staff members and students in University of Helsinki. The meeting was supported by the Teachers’ Academy in University of Helsinki. We have collected extensive summaries of the presentations to form this special issue. The summaries are found in both English and Finnish. To sum up the main ideas from the presentations. Firstly, although mathematical learning difficulties are common, we do need more research to be able to understand the possible cognitive precursors or environmental issues affecting learning and causing problems. Secondly, we need more studies about intervention programmes designed to support the mathematical skills development in children having problems in learning mathematics. Thirdly, we also need more studies validating the positive findings in individual studies, using the same assessment and intervention tools.

Osallistava ja tutkimuksellinen kemian opiskelu luokanopettajien koulutuksessa
Authors: Rukajärvi-Saarela Maija , Kiviniemi Kari , Aksela Maija
Published: March 2020

Luokanopettajat ovat avainasemassa lasten innostuksen herättämisessä sekä kemian tietojen ja taitojen kasvun tukemisessa alakoulussa. Tämän tutkimuksen päätavoitteeksi asetettiin kehittää luokanopettajan perus- ja täydennyskoulutukseen osallistava koulutusmalli, joka tarjoaa sekä sisällöllisiä että menetelmällisiä työkaluja kemian opettamiseen tutkimuksellisuutta korostaen. Opetus- ja opiskelukäytäntöjä kehitettäessä tukeuduttiin kemiaan luonnontieteenä, erityisesti sen kokeellisuuteen ja tutkimuksellisuuteen, sekä osallistavaa ja ammatillista kehittymistä tukevaa opettajankoulutusta käsitteleviin teoreettisiin lähtökohtiin. Koulutusmallia olivat tutkijan ja kouluttajien kanssa yhteisöllisesti kehittämässä yhteensä 168 peruskoulun opettajaa ja luokanopettajaopiskelijaa. Tutkimusaineiston muodostivat kolmen aallon yhteensä seitsemässä mesosyklissä hankitut kysely- ja havainnointiaineistot, opettajaopiskelijoiden kirjoittamat reflektoivat prosessipäiväkirjat ja koulutusmallien kehittämisprosessit sekä kehitetyt koulutusmallit. Aineistojen analysoinnissa käytettiin pääosin laadullisen sisällönanalyysin metodeja mutta mukana on myös määrällisiä osioita. Kehitetyssä koulutusmallissa workshop-tyyppisen koulutuksen sijaan työskennellään autenttisessa oppimisympäristössä, jossa myös oppilaat ovat osa-aikaisesti mukana. Koulutus on osallistavaa ja se tarjoaa innostavan ja turvallisen tavan harjoitella tutkimuksellisuutta ja sen ohjausta. Erityisen merkityksellisiä oppiminen kannalta ovat opettajien koulutuksen aikana saamat omakohtaiset oppimis- ja ohjaamiskokemukset sekä niiden pohdinnat, kouluttajien antama rohkaisu sekä yhteisöllinen tuki. Nämä rohkaisevat opettajia siirtämään tutkimuksellisuutta myös omaan opetukseen. Opettajaopiskelijoiden koulutuksen aikana kirjoittamat reflektoivat prosessipäiväkirjat ja niissä esille nostettujen asioiden lähes reaaliaikainen huomioiminen meneillään olevassa koulutuksessa ja yhteisissä pohdinnoissa tukevat korkeamman tason kognitiivisia prosesseja ja edesauttavat ammatillista kehittymistä. Tutkimustuotteena saatiin myös kuvaus siitä, kuinka tutkimuksellisuutta tukeva oppimisympäristö koulussa tulee järjestää opetukseen sopivaksi esimerkiksi välineistön ja tilojen suhteen. Oppimisympäristön suunnittelussa tulee huomioida myös positiivisen ja sallivan ilmapiirin merkitys oppimiseen.

In spring 2015, integrated chemistry education was the main focus for students attending the course The Central Areas of Chemistry Education II. The students specifically studied the interdisciplinary aspects of integration. Based on the research literature and the renewed National Curriculum (2014), they developed lesson plans supporting integrated chemistry education in secondary school. The lesson plans focused either on the co-operation between chemistry and mathematics or chemistry and English. In the article three students present the theoretical background for integrated chemistry education and the chemistry related to the lesson plans. All developed teaching materials (in Finnish) can be found online at LUMA.fi, the Finnish STEM education portal: http://www.luma.fi/materiaalit.
Combining science education with citizen science – experiences from a research institute-led science education project
Authors: Harjanne Atte , A. Karhu Juha , Ervasti Tiina , Tuomenvirta Heikki
Published: March 2020

Abstract Citizen science offers chances to gather observations and ideas and process data cost-efficiently while simultaneously increasing the outreach of the research. From the perspective of science education, it provides first-hand experiences about actual research work and personal contacts with researchers to its participants. Realizing this opportunity for mutual benefits, Finnish Meteorological Institute (FMI) has carried out a project combining citizen science with science education in co-operation with volunteering secondary schools. The project offered schools seven diverse research topics such as snow and birch pollen observations, development of weather service concepts and case studies in climate actions. Project work consisted of three parts: site visits, independent student work and reporting. Altogether 12 schools and over 200 students participated in the project during the fall and spring terms in the semester of 2014–2015. This paper describes the experiences from this first semester of the project. It is based on online questionnaires and interviews aimed at the participating students, teachers and researchers. Additional feedback was collected from an expert workshop. While actual research gains were modest, the satisfaction to the project was high within both the schools and FMI. Results encourage continuing this kind of cooperation and also studying further its educational impact.

Mathematics can be meaningful, easy and fun
Authors: Rossi Maarit
Published: March 2020

The negative attitudes are easily growing among children when mothers are telling to their daughters they were not good at mathematics or when newspapers’ cartoonist is drawing jokes about bad mathematics memories at school. It seems that the structure of mathematics lessons have not changed during the last decades. Schools seem to put too much attention to mechanical practice and mathematics teaching is too far from student interest and life. By diversifying teaching methods and using technology like adults are using it in everyday life, we can get students engaged to mathematics and change their attitudes positive towards mathematics.

This study aims to examine the effect of job satisfaction and organizational commitment on organizational citizenship behavior (OCB) in the Dinas Penanaman Modal and Pelayanan Terpadu satu Pintu (DPMPTSP) of Padang City. The data used in this study are primary data obtained from the questionnaire. The number of samples is 40 respondents where the number of samples is equal to the number of population so that the total sampling technique is used for sampling. The analysis technique used is a multiple linear regression method and hypothesis testing using the t test (partial). The results showed that the Job Satisfaction variable had no effect and was not significant for OCB with the acquisition of the calculated t value of 0.443 < t table 1.687, and the sig value of 0.660 > 0.05. While the organizational commitment variable has a positive and significant effect on OCB, with the acquisition of t count equal to 9.325 < t table 1.687, and the value of sig 0,000 > 0.05. This means that the willingness of employees to conduct OCB behavior is based more on their commitment to the Dinas Penanaman Modal and Pelayanan Terpadu satu Pintu (DPMPTSP) of the padang city than their job satisfaction.

Sequence completed – palynological investigations on Lateglacial/Early Holocene environmental changes recorded in sequentially laminated lacustrine sediments of the Nahe palaeolake in Schleswig-Holstein, Germany.
Authors: Krüger Sascha , Mortensen Morten Fischer , Dörfler Walter
Published: March 2020

The exploration of Lateglacial vegetation history in Schleswig-Holstein is elaborate and comprehensive. Despite being one of the most studied areas, regarding to the Lateglacial, no biostratigraphy covering the complete Lateglacial and Early Holocene periods without hiatus have so far been recovered. In this paper we present a biostratigraphy of the Nahe palaeolake, therewith intending to deal with this desideratum.The special strength of the presented sequence is expressed in the fact that these are the only palynologically investigated sequentially annual laminated limnic sediments of the Lateglacial in Schleswig-Holstein. These laminated sediments, as well as radiocarbon dating of botanical macrofossils and three geochemically confirmed cryptotephra layers (Laacher See Tephra, Vedde Ash and Saksunarvatn Ash), provide excellent chronological control and allow for a Europe-wide correlation. Particularly important is a complete discussion of the vegetation history and the spatial proximity to Late Palaeolithic sites, which renders it possible to evaluate potential human-environment-interaction long before classical palynological human indicators occur.
Hello, Neighbor: Carl and Fred Rogers and a Process of Person-centered Mentorship
Authors: Bolton Matthew J.
Published: March 2020

Though professionally unaware of each other, Carl and Fred Rogers had much–including religious upbringings, early career interests in child well-being, and primary aspects of their philosophies on life and human potential–in common. Carl Rogers became one of the most influential American psychologists to date, in formulating person-centered approaches to psychotherapy and life, and as a children’s television host Fred Rogers was–and has remained, in the eyes of generations of kids and adults alike over the last 50 some-odd years–in many ways perhaps the most exemplary late 20th century embodiment of Carl Rogers’ proposed way of being. Here, I–a mentor to motivated students in the meteorological and psychological sciences, and others in wider life–discuss my discovery of the person-centered approach, via childhood exposure to Fred Rogers; and provide perspective on the ways the person-centered approach can be utilized to foster more effective and meaningful mentorship and learning-based relationships.
Depression, sleeping pattern & suicidal ideation among medical students in Bangladesh: A cross-sectional pilot study
Authors: Hasan M Tasdik
Published: March 2020

Background: Depression is a major morbidity and the most common mental disorder among the medical students in medical schools globally. Undergraduate students suffer stress more due to their academic curriculum than the students of other faculties. In low resource settings like Bangladesh, there is a dearth in research on mental health of undergraduate medical students. This pilot study was conducted to add to the existing limited evidence by reporting the prevalence of depression, describing sleeping pattern & suicidal tendencies among medical students. Relevantly, we have investigated to the overall mental health status among the medical students in Bangladesh. Methods: This cross-sectional study was conducted in two medical colleges of Dhaka in between July 2013 to December 2013, among 221 Bangladeshi medical students from first to fifth year. By convenient sampling technique, data were collected by a pretested, structured, self-administered questionnaire and analysis was done by SPSS 18.0 version. Depression were assessed by validated PHQ-9 tool among the respondents. Goldberg’s General Health Questionnaire (GHQ-28) was used for assessing overall mental health status. Results: Depression was found in 38.9% of participants with 3.6%, 14.5%, 20.8% of being either severe, moderate and mild depression respectively. 17.6% medical students had suicidal tendency or attempted suicide at least for once after attending medical school. The sleeping hours were inadequate and altered after starting this stressful academic course. 33.5% medical students had poor mental health status. There was a statistically significant association between poor mental health status with age group of less than 22 years and initial academic study year (1st to 3rd of MBBS).Conclusion: The findings are suggestive of a higher prevalence of depression among early year medical students and marginal predominance in males. Suicidal tendency is also higher. These calls for further investigation with situation analysis, qualitative explorations and surveys to explore the burden of such disorders in Bangladesh.
In infancy, it’s the extremes of arousal that are ‘sticky’: naturalistic data challenge homeostatic models of self-regulation
Authors: Wass Sam
Published: March 2020

Most theoretical models of arousal/regulatory function emphasise the maintenance of homeostasis; consistent with this, most previous research into arousal has concentrated on examining individuals’ recovery following the administration of experimentally administered stressors. Here, we take a different approach: we recorded day-long spontaneous fluctuations in autonomic arousal (indexed via electrocardiogram, heart rate variability and actigraphy) in a cohort of 82 typically developing 12-month-old infants while they were at home and awake. Based on the aforementioned models we hypothesised that extreme high or low arousal states would be more short-lived than intermediate arousal states. Our results suggested that, contrary to this, both low- and high-arousal states were more long-lived than intermediate arousal states. The same pattern was present when the data were viewed over multiple epoch sizes from 1 second to 5 minutes; over 10-15-minute time-scales, high-arousal states were more long-lived than low- and intermediate states. One possible explanation for thesefindings is that extreme arousal states have intrinsically greater hysteresis; another is that, through ‘metastatic’ processes, small initial increases and decreases in arousal can become progressively amplified over time.
A Model of Monetary Transmission Mechanism
Authors: Maruyama Yuuki
Published: March 2020

The point of this model is that total investment in the economy is not determined by the equilibrium of the interest rate alone, but by the equilibrium of both the interest rate and the market price of risk (risk premium). In this model, the lower the discount rate or risk aversion of people, the higher the total investment. This model shows that when the interest rate is not at the zero lower bound, the total investment is only slightly affected by people's risk aversion, but at the zero lower bound, the total investment is inversely proportional to people's risk aversion. In addition, this model is used to analyze monetary policy. It is shown that the interest rate channel and the credit channel can be analyzed with the same formula and the effect of the interest rate channel is small. This explains why a central bank can greatly increase the total investment with small changes in the interest rate. Additionally, this paper analyzes fiscal policy, helicopter money, and government bonds.
Monopolistic Competition, Precautionary Savings, Coordination Failure
Authors: Maruyama Yuuki
Published: March 2020

By using the concept of precautionary savings instead of the life-cycle hypothesis in a model of monopolistic competition, this paper shows that recessions can occur even when prices are flexible. In this model, when buying goods, consumers face trade-offs not only with purchasing other goods but also with saving. Producers consider this and strategically determine prices and outputs. In this case, if consumers’ precautionary saving motive increases, coordination failure occurs and the aggregate supply decreases. In simple words, this is because the demand curve shrinks to the left instead of down.
