Internasjonal litteratur gir god dokumentasjon av hvilke faktorer som fremmer skoleutvikling. Konteksten som læringsprosesser foregår i, er viktig for læringsutbytte, og norsk skole avviker på mange områder fra den skolen vi finner i mange andre land. Det er derfor god grunn til å stille spørsmål ved om internasjonal forskning alene kan brukes som grunnlag for utvikling av norsk skole. Den studien som presenteres her, omfatter tre skoler i Midt-Norge som deltok i piloteringen av kompetanseutviklingen på ungdomstrinnet i skoleåret 2012/2013. Funnene er hentet fra intervjuer med rektor og en gruppe av lærere på skolene. Skolene i studien var svært ulike. Likevel ser vi at det er stort samsvar mellom skolene i hvilke faktorer som er viktige for å gi utvikling. I tillegg ser vi stort samsvar med de faktorene som internasjonal litteratur legger vekt på at fremmer skoleutvikling. Det viser at det i hovedsak er de samme faktorene som fremmer skolebasert kompetanseutvikling lokalt i Norge som er beskrevet i internasjonale studier, og at lokale, regionale og nasjonale forhold spiller mindre rolle. I artikkelen diskuterer vi hvordan funnene i vår studie er koblet til funn i tidligere studier.

English abstract
English title: A study on school-based competence development in a local context
International literature presents evidence of the factors that promote school de-velopment. But since context is important for learning and since the Norwegian school in many areas differs from the school we find in many other countries, there is good reason to question the relevance of international studies when planning school development projects in Norway. The present study includes three schools in Central Norway that participated in the pilot of the school-based competence development project in lower secondary school the year 2012/2013. The findings are drawn from interviews with the principal and a group of teachers in each school. The schools in the study were very different. Yet we see that there is a convergence between the schools in what factors that are important to promote development. In addition, we see a strong correlation with the factors that international literature emphasizes as important for school development. This shows that it is essentially the same factors that promote school development locally in Norway as described in international studies and that local, regional and national contexts matter less. In this article we discuss how the findings of our study are linked to findings in previous studies

I 10. klasse i ungdomsskolen må elevene gjøre valg av stor betydning for sitt senere liv. Hva skal de bli? Dette prosjektet fulgte 1025 ungdommer fra 10. klasse i 11 ungdomsskoler over i videregående skole og har gjennom spørreskjema sett på de valg elevene gjorde. Hvor godt informert var de forut for sine valg, hva eller hvem påvirket dem, og hvor fornøyd var de med de valg de hadde gjort? Informasjon om videregående skole var gitt på en rekke ulike måter. 77,7 % av elevene syntes de hadde fått nok informasjon til å kunne velge linje på videregående skole, men bare 37,1 % hadde fått individuell veiledning. Lærere og rådgiver hadde i liten grad påvirket elevenes valg. Prosjektet tyder på at familie, venner, lønn og kulturfaktorer som kjønn og yrkesstatus uansett overstyrer skolens rolle. Fag som utdanningsvalg og andre veiledningstiltak i ungdomsskolen ser ikke ut til å nå godt nok frem til de unge. Vårt grunnleggende spørsmål er om dagens 15–16-åringer er modne nok til å ta så viktige valg når det gjelder sin fremtid.

English abstract
Students in the 10th grade in lower secondary school have to make choices for upper secondary of great importance for their later life. What will be their future occupa-tion? This project followed 1025 students from 10th grade in 11 lower secondary schools into upper secondary. Did they have enough information to make their choice? 77.7% of students thought they had enough information to select direction in upper secondary school. Only 37.1% had received individual counseling. Teachers and adviser had little impact on the students’ choices. Parents and friends were far more important. The project suggests that family, possible income and cultu-ral factors such as gender and job status are more important than the impact of information given in the school. Our basic question is whether today’s 15–16-year olds are mature enough to make such important decisions regarding their future

Utdanningene i Norge er i endring. Barnehagen fikk nye rammeplaner i fjor, og i 2013 ble førskolelærerutdanningen endret til en barnehagelæreutdanning. Det innebar store endringer i læreplanen eller det som kalles «Rammeplan for barnehagelærerutdanningen». Følgeforskningsgruppen for Barnehagelærerutdanningen (BLU) viser at mange ennå strever med å finne ut hvordan en i praksis skal drive utdanningen innenfor de tverrfaglige fagområdene. I grunnopplæringen er det fastsatt en ny, overordnet del i læreplanverket – hvordan den skal tolkes, strever mange ute i de enkelte kommunene med. Hvordan skal en legge til rette for dybdelæring? Og hva betyr nå egentlig det?
Begynneropplæring – et begrep i stadig endring? En diskursanalyse av meldinger til Stortinget, fra seksårsreformen til fagfornyelsen
Authors: Hoff-Jenssen Reidun 
Published: October 2023

Begynneropplæring er et begrep som brukes hyppig i politiske og profesjonsfaglige sammenhenger i Norge. Tidligere forskning har beskrevet begynneropplæring som et uklart begrep med en manglende felles innholdsforståelse. Denne artikkelen utforsker hvilket meningsinnhold begynneropplæring gis i utdanningspolitiske dokumenter. Gjennom diskursanalyse av syv meldinger til Stortinget ble det politiske meningsinnholdet identifisert i fire diskurser: overgangsdiskurs, ressursdiskurs, kartleggingsdiskurs og kompetansediskurs. Diskursene representerer ulike dimensjoner av begynneropplæring, og synliggjør at begynneropplæring er et flersidig begrep som over tid er blitt tilført nytt innhold. Diskursene kan indikere mulige implikasjoner for skolens praksis og hva som kan være ønskelig å vektlegge i begynneropplæringen.
ENGLISH ABSTRACT
“Initial schooling” – a constantly changing term?
“Initial schooling” (begynneropplæring) is a concept frequently used in political and professional contexts in Norway. Previous research has described it as an unclear concept with a lack of a common understanding of its contents. This paper explores the meaning of initial schooling in educational policy documents. The analysis of 7 White papers identified four discourses of initial schooling: transition discourse, resource discourse, assessment discourse, and competence discourse. The discourses represent different dimensions of initial schooling and show that it is a multifaceted concept in which new content has been added over time. The discourses indicate possible implications for the school’s practice, hence what may be desirable to emphasize in initial schooling.

Aonla based multistoried agroforestry with vegetables is a promising solution to mitigate the devastating effects of climate change by offering multidimensional benefits. Disappointedly, Bangladeshi farmers are less equipped about the cultivation techniques, economics, and yields of multistory agroforestry production systems. Consequently, the goal of the current study was to evaluate the profitability and yield potentiality of aonla-based multistoried broccoli production system during the period of November 22 to March 23. Three separate multistory agroforestry systems were covered by the three treatments, while an open field served as the control treatment. to keep track of the system's expansion and economic success; soil analysis, photosynthetically active radiation, plant height, number of leaves, head length, head width, head weight, total yield, BCR, and LER were calculated following different established methods. While compared to sole cropping, the agroforestry approach drastically reduced the production of broccoli by 89%. Soil organic matter, nitrogen, phosphorous, potassium, and sulfur were higher in agroforestry system than that of control plot. In fact, the agroforestry system had some negative effects on the rate of crop growth in understored conditions. Despite, net return and BCR from aonla-based multistoried agroforestry system were 4-11 lakh and 2.24-3.98, which was 69-87 and 41- 67 %, respectively higher than sole cropping systems. The LER of aonla based multistoried agroforestry system was 3.20. The major conclusions show that aonla orchards can be converted to agroforestry systems to increase productivity, generate money, and protect the environment, however due to poor performance, broccoli cannot be grown in multistory systems.
Wpływ nawozów zawierających wolne aminokwasy na plonowanie współczesnej oraz dawnych odmian pszenicy zwyczajnej w produkcji ekologicznej
Authors: Kołodziejczyk Marek , Gwóźdź Kamil 
Published: October 2023

Celem badań było określenie wpływu nawozów aminokwasowych na wielkość i strukturę plonu ziarna współcześnie uprawianej oraz starych odmian pszenicy zwyczajnej ozimej w produkcji ekologicznej. Ocenie poddano następujące odmiany pszenicy: RGT Kilimanjaro, Ostka Grodkowicka, Square Head Grodkowicka, Egipcjanka, Nadwiślanka i Blondynka. Warianty nawozowe obejmowały: obiekt bez nawożenia dolistnego, Fertileader Tonic, Ecovigor AA, Fertileader Tonic + Ecovigor AA, Aminosol, Fertileader Tonic + Aminosol. Spośród ocenianych odmian pszenicy największym plonem ziarna odznaczała się współcześnie uprawiana odmiana RGT Kilimanjaro, która plonowała średnio na poziomie 7,27 t ha–1. Stare, regionalne odmiany pszenicy wykształcały plony ziarna od 36,3 do 50,3% mniejsze. W tej grupie odmian największym potencjałem plonowania odznaczała się Nadwiślanka, a najmniejszym Blondynka. Mniejsze plony ziarna starych odmian pszenicy były efektem słabszej krzewistości roślin, mniejszej ilości wykształconych ziaren w kłosie oraz masy 1000 ziaren w porównaniu z pszenicą współcześnie uprawianą. Aplikacja nawozów aminokwasowych powodowała przyrost plonu ziarna w zakresie od 2,4 do 7,2%. Istotną zwyżkę plonu stwierdzono po zastosowaniu preparatu Fertileader Tonic łącznie z nawozami Ecovigor AA oraz Aminosol.

Abstract
The aim of this paper was to propose an innovative solution for the management and payment planning processes in manufacturing enterprises with the support of an in-house SAP system in accounting and administration of services in order to streamline enterprise processes. The methods used were analysis of internal environment, observation method, analysis of written documents, analysis of microenvironment of manufacturing enterprises, SWOT analysis, internal data from the SAP system, process structural analysis and process map. The results obtained, in conjunction with application of scientific research methods, contributed to development of an application that reduces risk of negative reputation of manufacturing enterprises and promotes business partnerships in supplier-customer relationships where late payment of obligations occurred due to an out-dated management and payment planning processes. The new application is a potential solution reducing risks of payment of obligations in processes of managing and planning payments for SMEs.
New Algorithm Permitting the Construction of an Effective Spanning Tree
Authors: Belkacem Salima Nait , Abbas Moncef 
Published: October 2023

Abstract
In this paper, we have done a rapid and very simple algorithm that resolves the multiple objective combinatorial optimization problem. This, by determining a basic optimal solution, which is a strong spanning tree constructed, according to a well-chosen criterion. Consequently, our algorithm uses notions of Bellman’s algorithm to determine the best path of the network, and Ford Fulkerson’s algorithm to maximise the flow value. The Simplex Network Method that permits to reach the optimality conditions manipulates the two algorithms. In short, the interest of our work is the optimization of many criteria taking into account the strong spanning tree, which represents the central angular stone of the network. To illustrate that, we propose to optimize a bi-objective distribution problem.

Abstract
This study examines the issue of distribution network design in the supply chain system. There are many production factories and distribution warehouses in this issue. The most efficient strategy for distributing the product from the factory to the warehouse and from the warehouse to the customer is determined by solving this model. This model combines location problems with and without capacity limits to study a particular location problem. In this system, the cost of production and maintenance of the product in the factory and warehouse is a function of its output. This increases capacity without additional costs, and ultimately does not lose customers. This algorithm is a population-based, innovative method that systematically combines answers to obtain the most accurate answer considering quality and diversity. A two-phase recursive algorithm based on a scattered object has been developed to solve this model. Numerical results show the efficiency and effectiveness of this two-phase algorithm for problems of different sizes.

Abstract
Adequate and desirable connections between suppliers and customers necessitate an appropriate flow of information. Therefore, a promising and proper data collaboration in the supply chain is of tremendous significance. Thus, the study’s main objective is to provide multiple objective programming models under uncertain conditions to assess the performance of suppliers. To meet that aim, a case study for the reliability assessment of the presented model is carried out. That section is associated with supply chain visibility (SCV). Likewise, the likelihood of unpredicted and undesirable incidents involving supply chain risk (SCR) is taken into consideration. The intimate relation between visibility and risk of the supply chain is deemed efficient for the performance of the supply chain. Incoherence in maximization and minimization of SCR and SCV and other factors, including costs, capacity, or demand, necessitates multiple objective programming models to assess suppliers’ performance to accomplish the before-mentioned aims. The study’s results indicate the high reliability of the proposed model. Besides, the numeral results reveal that decision-makers in selecting suppliers mainly decrease SCR and then attempt to enhance SCV. In conclusion, the provided model in the study can be a desirable model for analyzing and estimating supplier performance with SCR and SCV simultaneously.

Abstrak. Ferroelektrik merupakan bahan elektronik khususnya dielektrik yang dapat diaplikasikan sebagai kapasitor. Ferroeletrik mempunyai kemampuan mengubah arah medan listrik internalnya dengan menggunakan medanl istrik yang sesuai. Barium titanat merupakan bahan yang bersifat ferroelektrik yang dapat didoping dengan bahan zirconium dan dapat dibuat dalam bentuk film tipis. Penambahan doping zirconium pada barium titanat akan meningkatkan konstanta dielektrik bahan. Pembuatan film tipis Barium Zirkoniun Titanat dengan komposisi (BaZr0.45Ti0.55O3) telah berhasil dibuat dengan menggunakan metode sol-gel. Variasi suhu annealing yaitu 600oC dan 650oC dengan waktu tahan 1 jam dan dikarakterisasi menggunakan difraksi sinar-X (XRD) dan scanning electron microscopy (SEM). Hasil karakterisasi XRD mendapatkan parameter kisi a = b = 3,97Ȧ danc = 4,25 Ȧ sehingga struktur kristalnya adalah tetragonal. Tingkat kekristalan semakin tinggi dengan bertambahnya suhu annealing yang ditandai dengan meningkatnya intensitas. Karakterisasi SEM menunjukkan pada suhu annealing 600oC ukuran butiran belum terlihat jelas sehingga tidak dapat ditentukan ukuran butirannya. Pada suhu 650oC ukuran butirannya dapat ditentukan dengan nilai ukuran butiran rata-ratanya adalah sekitar 134,5 nm. Abstract. Ferroelectric is an electronic material, the dielectric in particular, which can be applied as a capacitor. Ferroelectric is able to change the direction of its internal electric field by the use of a suitable electric field. Barium Titanate is a ferroelectric material which can be doped with zirconium and made in the form of a thin film. The addition of zirconium doping to Barium Titanate will increase the dielectric constant of the material. The making of Barium Zirconiun Titanate thin film with the composition (BaZr0,45Ti0,55O3) has been successfully prepared using the sol-gel method. The annealing temperature variations are 600oC and 650oC with a 1 hour holding time and characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD characterization results obtain lattice parameters of a = b = 3.97 and c = 4.25 Ȧ, and thereby, the crystal structure is tetragonal. The crystallinity level is highly increasing with increased annealing temperature, indicated by increased intensity. SEM characterization shows that at annealing temperature of 600oC, the grain size is not clearly visible, so the grain size cannot be determined. At a temperature of 650oC, the grain size can be determined with the average grain size of about 134.5 nm.

This study aimed to prepare precipitated calcium carbonate (PCC) from pearl oyster shells by dissolving with HNO3 solution, carbonation with carbon dioxide, and sonication. Shells with a size of 200 mesh were calcined at 900 ºC for 3 hours, dissolved in 0.8 M nitric acid solution and added ammonia to form an alkaline medium. Then it was flowed with CO2 gas (carbonation) for 30 minutes and continued sonication for 30 minutes. The precipitate formed after washing is white with a CaO percentage of 98.36%. This percentage is higher than the CaO in clam shells before being purified. PCC that was successfully extracted had crystalline phases of calcite (2θ) 29.3, 35.88, and 39.4° and vaterite (2θ) 24.8˚, 27.0˚, 32.7˚, 43.8˚ and 55 ,7˚. The calcite and vaterite crystal phases can also be seen from the SEM images which show cubic (calcite) and spherical (vaterite) shapes. FTIR results show wave numbers 708, 748, 879, 1087, 1420, 1465 and 1481.3 cm-1 which are the identity of the vibration of the carbonate group of vaterite and calcite in PCC. The particle size of the formed PCC is 2.434 µm. Based on the results of the characterization carried out, it can be concluded that the PCC of the shells has been successfully carried out and formed calcite and vaterite crystal phases.
