Published: October 2023

Many Asian countries use the bark of the Magnolia for medicinal purposes. Magnolia has many medical uses, including regulating GI motility, treating cough and asthma, preventing cardiovascular disease, and treating mental illness and brain disorders. To date, 118 magnolia species have been discovered. However, the International Union for Conservation of Nature has designated 231 species as vulnerable and critically endangered. Magnolia leaves yielded 20 isolated chemicals, including 16 lignans with 6 distinct structural types, such as honokiol, veraguensin, sitosterol, and magliflonenone. Magnolia species show pharmacological activities like Neuroprotective, anti-cancer, Anti-microbial, Antiplatelets, Anti-asthmatic, Gastrointestinal, and Hormone regulation. Magnolia bark extracts such as honokiol 2',6-di-(5-propenyl)-1,1'-biphenyl-2,2'-diol, have been demonstrated to benefit health. In recent in vitro and preclinical research, honokiol was found to have anti-inflammatory, anti-angiogenic, anti-oxidative, and anti-cancer activities. Honokiol and magnolol prevented the thromboxane B2 synthesis in response to thrombin, arachidonic acid, and collagen. So, soon, if we cultivate and save the endangered magnolia species through biotechnological means, it will be a boon for mankind.

Published: October 2023

Abstract: The primary goal of this study project is to look into the intricate links between Foreign Direct Investment (FDI), the performance of India's stock market, and the country's Gross Domestic Product (GDP). Our primary goal in researching these relationships is to obtain a better understanding of the critical role that FDI plays in shaping both stock market dynamics and India's overall economic growth and stability. This analytical investigation is based on a large dataset spanning the years 2015- 2016 to 2020-2021. We used two statistical tools, correlation analysis and ANOVA (Analysis of Variance) calculations, to quantify these associations. With the use of these analytical tools, we aim to offer a deeper comprehension of how FDI affects India's stock market performance and, consequently, its overall economic health.
A synthesized distribution model: Asymmetric information, agency problem, and intertemporal optimization
Authors: Jiang Jun
Published: October 2023

A firm’s policy of distribution over current and future time periods influences the capital structure of the firm and its profitability. Managers decide on the amount of effort input in such a context of financial structure to maximize their utility. Nevertheless, shareholders’ preferred distribution of income is determined by the goal of corporate value maximization. The study aims to reach an optimal level of income distribution and reinvestment over current and future periods in which both the manager’s utility and shareholders’ corporate value have been maximized. The study adopts Lagrange’s multipliers method and the discounted cash flow valuation model of corporate value maximization. By processing a method of mathematical deduction and optimization, the study aims to reach an optimal equilibrium level of the dividend distribution model and explore key factors in the model for the determination of the distribution of income. As a result, the study concluded an optimal dividend distribution model, in which six factors jointly determine a theoretical equilibrium of optimization. These factors consist of the capital structure of the firm, the tax shield from debt financing, the growth rate of the dividend, dividend tax, the investment strategy of the principal, and the cost of capital.
Electrifying Opera, Amplifying Agency. Artistic results. reflection and public presentations (PhD)
Authors: Kristin Norderval
Published: October 2023

Exposition of PhD research for PhD fellow at the Oslo National Academy of the Arts, Academy of Opera, Kristin Norderval.

This artistic research project examines the artistic, technical, and pedagogical challenges of developing a performer-controlled interactive technology for real-time vocal processing of the operatic voice. As a classically trained singer-composer, I have explored ways to merge the compositional aspects of transforming electronic sound with the performative aspects of embodied singing.

I set out to design, develop, and test a prototype for an interactive vocal processing system using sampling and audio processing methods. The aim was to foreground and accommodate an unamplified operatic voice interacting with the room's acoustics and the extended disembodied voices of the same performer. The iterative prototyping explored the
performer's relationship to the acoustic space, the relationship between the embodied acoustic voice and disembodied processed voice(s), and the relationship to memory and time.

One of the core challenges was to design a system that would accommodate mobility and allow interaction based on auditory and haptic cues rather than visual. In other words, a system allowing the singer to control their sonic output without standing behind a laptop. I wished to highlight and amplify the performer's agency with a system that would enable nuanced and variable vocal processing, be robust, teachable, and suitable for use in various settings: solo performances, various types and sizes of ensembles, and opera. This entailed mediating different needs, training, and working methods of both electronic music and opera practitioners.

One key finding was that even simple audio processing could achieve complex musical results. The audio processes used were primarily combinations of feedback and delay lines. However, performers could get complex musical results quickly through continuous gestural control and the ability to route signals to four channels. This complexity sometimes led to surprising results, eliciting improvisatory responses also from singers without musical improvisation experience.

The project has resulted in numerous vocal solo, chamber, and operatic performances in Norway, the Netherlands, Belgium, and the United States. The research contributes to developing emerging technologies for live electronic vocal processing in opera, developing the improvisational performance skills needed to engage with those technologies, and exploring alternatives for sound diffusion conducive to working with unamplified operatic voices.

A Brief Mindfulness-Based Intervention for Stress, Pain, Emotion and Attention Regulation in Military Service Members with Mild Traumatic Brain Injury
Authors: Uomoto Jay , MacNulty William K. , Peterson Seattle M.
Published: October 2023

Aim The primary aim of this study was to conduct an open pilot
clinical trial of a brief mindfulness-based intervention for persistent
postconcussion symptoms that occur after mild traumatic brain injury in
military service members. For many service members, operational tempo
and other time constraints may prevent them from completing a standard
mindfulness-based stress reduction course. Thus, this study sought to
examine the effectiveness of a five-session intervention called
Mindfulness-Based Stress, Pain, Emotion, and Attention Regulation
(MSPEAR). Methods Participants were active duty service members
with a history of mild traumatic brain injury (TBI) and persisting
postconcussion symptoms, all of whom were recruited from an outpatient
TBI rehabilitation program at a military treatment facility. Of the 38
service members that were initially enrolled, 25 completed the 5-session
MSPEAR intervention, and 20 returned for a 5-week follow-up evaluation.
Questionnaires assessing perceived stress, positive affect, pain
interference and catastrophizing, sleep disturbances, perceived
behavioral and attention regulation, self-efficacy, and satisfaction
with life were administered at pre-intervention, post-intervention, and
at 5-week follow-up intervals. Neuropsychological testing at
pre-intervention and 5-week follow-up included performance validity
measures, attention, working memory, and executive function measures.
Results Improvements in perceived stress, positive affect,
behavioral regulation, metacognition, sleep disturbance, self-efficacy,
and satisfaction with life were found immediately after the MSPEAR
intervention and were maintained at the 5-week follow-up. Magnification
and helplessness aspects of pain catastrophizing improved when comparing
pre-intervention to the 5-week follow-up. Pain interference was not
significantly different across study assessment times.
Neuropsychological testing revealed improvements in sustained attention,
working memory, cognitive flexibility, and inhibitory control when
comparing pre-intervention to the 5-week follow-up assessment.
Conclusions The MSPEAR intervention appears to show promise as
a brief and effective therapy for specific postconcussion symptoms after
mild traumatic brain injury in military service members. Each of the
components of MSPEAR including stress, pain catastrophizing, emotion,
and attention regulation showed improvements in this study, and bears
further investigation in a larger scale, preferably randomized
controlled trial in those active duty military service members who
experience persisting symptoms after a mild traumatic brain injury.
An Uncertainty-Based Voltage Control Model of a Smart Active Network in the Presence of Electric Vehicles: A Distributed Optimization Approach
Authors: Nazari Mahla , Esmaeili S. , Yazdi Mojtaba Barkhordari
Published: October 2023

Nowadays, Distributed Energy Resources (DERs) and Electric Vehicles
(EVs) are being increasingly used in smart distribution networks. There
are concerns regarding the use of DERs and EVs which are twofold: (i)
they may lead to grid voltage variation and (ii) they have uncertainty
in power production. In this paper, a distributed voltage control method
is proposed in the simultaneous presence of DERs and EVs preserving the
independence and reducing the communications between them while
considering probabilistic behaviors. The proposed objective function
improves the system voltage profile with the lowest rate of change in
the active and reactive power of DERs and EVs. For this purpose, a
method is developed for converting the centralized optimization problem
to the distributed optimization problem using Dual-Decomposition (DD)
and Alternating Direction Method of Multipliers (ADMM) algorithms based
on Peer-to-Peer (P2P) communication capabilities of DERs and EVs. The
uncertainty of DERs and EVs are modelled by utilizing a scenario-based
approach and a Two-Point Estimation Method (2PEM), respectively. The
results on the modified IEEE 69-bus test system show that the proposed
method can improve the voltage deviation of the worst bus by about 7%,
and also reduce grid losses by about 48%.
Forskningsformidling – til hvem og hvorfor?
Authors: Farbrot Audun
Published: October 2023

Forskningsformidling skal ved siden av forskning og utdanning være én av tre kjerneaktiviteter ved norske universiteter og høyskoler. Svært mange av institusjonene har da også pekt ut formidling som et satsingsområde.
Det er fortsatt langt igjen før formidling har samme status, posisjon og omfang som universitetenes to andre kjerneoppgaver, forskning og utdanning.
Jeg identifiserer ti ulike grunner for å drive forskningsformidling. Her har det skjedd en dreining de siste årene i retning av at PR, omdømme og studentrekruttering har blitt et stadig viktigere motiv for å drive forskningsformidling, sett fra institusjonenes ståsted.
Med utgangspunkt i et tenkt universitet eller en tenkt høyskole identifiserer jeg tolv ulike målgrupper for forskningsformidling som jeg ser i sammenheng med motivene for å formidle. Særlig vil jeg utforske og forsøke å åpne den «svarte boksen» med merkelappen allmennheten–eller offentligheten.
Det er mitt håp at jeg gjennom artikkelen utvikler byggesteiner som kan brukes i arbeidet med å utvikle strategi, politikk og indikatorer som fremmer mer og bedre forskningsformidling. Til slutt drister jeg meg til å foreslå en tistegs plan for bedre og mer målrettet forskningsformidling.

Quo vadimus? Tre scenarioer for samarbeidsmodellen i fremtidens arbeidsliv
Authors: Ravn Johan E.
Published: October 2023

Stilt overfor begrepet «partene i arbeidslivet» vil de fleste tenke på interessemotsetning og forhandling mer enn felleskap og samarbeid. Men partene i arbeidslivet er også skaperne av «den norske samarbeidsmodellen». Artikkelens tema er hvorvidt denne har noen fremtid.Innledningsvis pekes på modellens mest sentrale trekk. Myndighetene vedtar lover og legger forholdene til rette. Arbeidsgiverne eier produksjonsmidlene, og deres styringsrett anerkjennes av arbeidstakerne, som på sin side eier arbeidskraften, og deres organisasjonsrett aksepteres av arbeidsgiverne. Gjennom samvirke over tid har det vokst frem en høy grad av tillit og et omfattende samspill. Dette kalles samarbeidsmodellen, arbeidslivets praktiske samarbeidsferdigheter, som har bidratt til senket konfliktnivå og styrket konkurransekraft gjennom produktivitetsutvikling og innovasjonsaktivitet.Neste skritt er å posisjonere samarbeidsmodellen i forhold til andre arbeidslivsmodeller, og det pekes på forskjeller med hensyn til for eksempel autoritet, kommunikasjon, medvirkning, konflikt og tillit. Men norsk arbeidsliv er del av en globalisert økonomi, og basert på en identifikasjon av krefter og faktorer som kan true eller videreutvikle modellen utvikles tre ulike scenarier for samarbeidsmodellen: forsvar av det som en gang var; overgivelse og kapitulasjon, eller revitalisering og innovasjon. Å fastslå hvilken fremtid samarbeidsmodellens går mot er ikke gitt noen, men dens tilblivelse var en møysommelig og villet prosess. En rimelig antakelse er at dens fortsatte betydning er betinget av styrken i interessefellesskapet som stiller seg bak den.
Har kvaliteten på lærere falt over tid?
Authors: Møen Jarle , Salvanes Kjell G. , Thorsen Helge Sandvig
Published: October 2023

Bekymringer om opptakskravene til lærerstudiet er et tilbakevendende tema i offentlig debatt, og myndighetene har også forsøkt ulike tiltak for å bedre rekrutteringen. Det er derfor interessant å studere de lange linjene i rekrutteringen til læreryrket. Vi analyserer hvordan de som søker seg til læreryrket, har prestert på kognitive tester brukt ved sesjon. Vi finner at gjennomsnittlig skår for mannlige lærere har falt ti persentiler fra lærerårskullet født i 1950 til lærerårskullet født i 1980. I tillegg har andelen av undervisningspersonalet med lektorkompetanse i allmennfaglig studieretning falt dramatisk. Fallet er spesielt sterkt for realister. Vi finner videre at fallet i kognitiv skår har kommet parallelt med et fall i relative lønninger for lærere og lektorer. Vi viser dessuten at flere forlater læreryrket i gode tider, når utvalget av godt betalte jobber er større. Videre forskning må til for å avklare om fallet i kognitiv skår kan knyttes kausalt til lønnsutviklingen, og ikke minst om det målte kvalitetsfallet har hatt betydning for elevenes læring.

Spectrophotometric Analysis of Nitrite in Gunshot Recentness Examinations from Non Toxic Ammunitions: Expanding the Frontiers of Forensic Chemistry
Authors: Oliveira Marcelo Firmino de
Published: October 2023

Nitrite ions consist on an important chemical clue related to gunshot examination, concerning to estimation of the time since discharge. Current forensic laboratory methods for nitrite analysis in gunshot residues are well established for investigating conventional ammunition residues. However, the use of these methods to analyze the so-called ecological or “non-toxic” ammunition has been less studied. Here, we have developed a spectrophotometric flow injection analysis method to test nitrite in samples of “non-toxic” ammunition residues. The ammunition used in these experiments was the NTA (non-toxic ammunition) model, .38 caliber, We also investigated the kinetics of nitrite decomposition for this type of ammunition over time. Sulfanilic acid and 1-naphthylethylenediamine in acetic acid were used as colorimetric reagents. The linear dependence of the spectrophotometric signal on the nitrite concentration was as follows: A = 2.07 x 104 µmol-1 L [NO2-] + 6.78 x 10-3 with a correlation coefficient (r) of 0.9994. The standard deviation (SD) of the analytical curve was 3.17 x 10-3 resulting in a limit of detection (LOD) = 0.46 µmol L-1 and a limit of quantification (LOQ) = 1.56 µmol L-1. The proposed instrumental method was more sensitive than conventional colorimetric tests and permitted the detection window to be extended to 32 days while ensuring the safety and reliability required for forensic analysis, in comparison to 7-10 days usually proposed for conventional ammunition. Therefore, the proposed method can be safely employed in forensic laboratories for routine analysis of nitrite ions in GSR samples from ecological or “non-toxic” ammunition.
Virtual Experiments in Forensic Sciences
Authors: Loera Omar Mireles
Published: October 2023

Given that it is not practical to collide several vehicles to try to repeat the damage pattern of a damaged vehicle, just as it is not possible to set fire to several industrial warehouses to analyze the pattern of fire behavior inside a warehouse where the origin of the fire, the forensic expert must have contemporary techniques that allow him to carry out non-invasive experimentation with the aim of repeating the conditions in which an event occurred. In this paper, the fundamentals of mathematical modeling of forensic phenomena are presented, as well as some examples of virtual experimentation applications used in judicialized cases.
Head Space-GC Analysis of N, N-Diethyl-M-Toluamide (DEET) in Human Postmortem Specimens: A Forensic Case Report
Authors: Paul Subhra Kumar
Published: October 2023

In India, self-poisoning through pesticides is an increasingly common form of suicide. Although deleterious insect repellents (sub-classification of pesticides) are regulated or interdicted, but significant data related to misuse can be procured. Meanwhile, the emergence of novel commercially manufactured products containing insect repellant as a prime ingredient without public and scientific apprehension regarding detrimental impacts has exacerbated the circumstances. Forensic examination of the viscera of the deceased discerned that the death was attributable to Diethyltoulamide intoxication. As no conspiracy behind the death was evident, hence it was pellucid to comprehend that the insect-repellant product was self-administered. Headspace GC analysis of viscera showed noteworthy results in concern to the identification of Diethyltoulamide. This study attempts to identify the most appropriate pesticide and determine whether it is present in biological matrices. The samples were received from the hospital and processed in the Forensic Science Laboratory for testing on possible poisoning. The pesticides Malathion, Dicholorovos, Baygon, and Lindane were utilised as a kind of control. The extraction of pesticides from various biological matrices was done using the solvent extraction method.

Published: October 2023

The problem faced by English teachers when teaching listening was how to make all students focus on the learning material and be active, considering that not all students can focus on what is conveyed and often there were students who also busy playing cellphones. To overcome this problem, the English teacher sometimes asked students some questions to regain their learning intention. The objective of this research is to analyze the strategies in teaching listening to students and the problems found by the English teacher in teaching listening as well as how they overcome the problems. The research was conducted by using descriptive qualitative research. The subject of this research was a English teacher. The research collected the data through interview guidance and uses library research, which compiles extensive documentation on a single or a number of topics. Both original sources and secondary sources are used in this investigation. As a conclusion, this study can argue that using multimedia to teach listening suppresses some of the unnatural aspects of the more conventional ear training in EFL classrooms while also bringing about a number of potential advantages.

En la educación superior, la adquisición de aprendizajes implica la movilización de los conocimientos y habilidades propios de un quehacer profesional. La secuencia que sigue el estudiantado, para lograr las competencias necesarias para desarrollar su profesión con efectividad, debe considerar experiencias prácticas que favorezcan una implicación activa. Por otra parte, si el proceso desarrollado por quienes aprenden es percibido como positivo, se favorece la motivación y el aprendizaje profundo. Por ello, el objetivo de este trabajo fue analizar las valoraciones sobre el proceso de enseñanza y aprendizaje de los estudiantes de trabajo social en el contexto de las prácticas profesionales. Con base en un enfoque cuantitativo, en este trabajo se evaluó calidad de la enseñanza con el Course Experience Questionnaire (CEQ) y la forma que los estudiantes abordan el aprendizaje con el Study Process Questionnaire (SPQ). Los participantes fueron 163 estudiantes de Trabajo Social de tres cursos sucesivos de una universidad chilena. Los datos se analizaron con estadística descriptiva e inferencial. Los resultados muestran que el estudiantado valora positivamente la docencia y el aprendizaje profundo; además, se evidencia que la carga académica es considerada excesiva por parte de ellos. Estos datos demuestran la importancia que tiene una valoración positiva de la experiencia académica en la adquisición del aprendizaje, así como la relevancia del acompañamiento al estudiantado en las prácticas profesionales para favorecer el aprendizaje profundo.

Jenis penelitian yang dapat dilakukan oleh guru cukup banyak  di antaranya adalah Penelitian Tindakan Kelas (PTK).   Sebagian besar guru, baik guru SD/MI, SMP/MTs, dan SMA/MA menyatakan bahwa pada analisis data inilah bagian yang tersulit dalam PTK. Hal ini tidaklah 100%  benar, karena sebenarnya pada bagian inilah hal yang sangat mengasyikkan. Orang akan bisa karena terbiasa, orang akan tidak bisa karena belum terbiasa. Kata-kata itu nampaknya benar, artinya guru merasa tidak bisa melakukan analisis data dalam PTK karena memang belum terbiasa. Untuk membiasakan guru-guru dalam menganalisis data penelitiannya diperlukan aplikasi program statistika. Salah satu aplikasi program statistika adalah SPSS.
