Kuntoutuminen toimintamahdollisuuksina – Ammattilaisten käsitykset nuorten kuntoutujien toimijuudesta
Authors: Salminen Jarkko , Häikiö Liisa 
Published: March 2022

Tässä tutkimuksessa tarkastellaan, mitä nuorten kuntoutujien toimijuuden muodostuminen edellyttää kuntoutuksen ammattilaisten näkökulmasta. Laadullista tutkimusta varten haastateltiin ammattilaisia, kuten psykologeja, sosiaalityöntekijöitä, opettajia ja erityisopettajia, neljässä ryhmähaastattelussa. Haastatteluissa keskityttiin erityisesti mielenterveyden ja käyttäytymisen häiriöiden vuoksi kuntoutukseen osallistuvien nuorten toimijuuteen. Toimintamahdollisuuksien lähestymistapaa soveltamalla tutkimus osoittaa, että nuoret tarvitsevat mahdollisuuksia toimia omaehtoisesti ja tehdä omassa elämässään terveyteen, sosiaalisiin suhteisiin sekä opiskeluun ja ammattiin liittyviä valintoja. Ammattilaisten näkökulmasta toimintamahdollisuuksien muodostuminen mahdollistaa kuntoutumisen ja on kuntoutuksen edellytys. Kuntoutus ei tue toimijuutta, jos se ainoastaan vastuullistaa nuoria tarjoamatta heille aitoja ja omaehtoisia valinnan mahdollisuuksia. Toisin sanoen toimintamahdollisuudet eivät ole vain yksilöstä kiinni vaan kytkeytyvät toimintaympäristöön. Tästä syystä kuntoutukseen suunnattujen resurssien vähyys ja joustamaton organisointi usein vaikeuttavat toimijuuden ja toimintamahdollisuuksien muodostumista. Esteenä ovat esimerkiksi vähäiset resurssit terveydenhuollossa ja ammatillisessa kuntoutuksessa. Toisaalta joustamattomat tavat tarjota terveyspalveluita tai tukea nuorten oppimista ja sosiaalisia suhteita koulussa ovat esteenä toimijuuden muodostumiselle ja siten kuntoutumiselle.
Abstract
Agency of young recoverees from the viewpoint of rehabilitation professionals
In this study, we examine the requisites for agency of young recoverees from the perspective of rehabilitation professionals. For this qualitative study, professionals such as psychologists, social workers, teachers/special educators were interviewed in four group interviews. The interviews focused in particular on the agency of young people in rehabilitation due to mental and behavioral disorders. Applying the capability approach, the article suggests that young people need opportunities to act independently and make choices in their own lives related to health, social relations, education and profession. From the point of view of the professionals, this is a prerequisite for rehabilitation. Rehabilitation does not support agency if it only makes young people responsible without offering them genuine choices in life. In other words, the formation of capabilities does not dependent only on the individual but also on the environment. For this reason, the scarcity of resources for rehabilitation and rigid organization often hinder agency and capabilities. Obstacles include, for example, limited resources in health care and vocational rehabilitation. On the other hand, inflexible ways of providing health care services or supporting young people’s learning and social relations at school stymies the formation of agency, and therefore, rehabilitation.

Published: March 2022

Cold stress-induced analgesia (c-SIA) has been evaluated in male Wistar rats injected with cannabinoid receptors type 1 and a2-adrenergic receptor agonists and antagonists in different combinations before or after stress exposure.
The aim of the study was to evaluate whether the endogenous cannabinoid and the adrenergic systems influenced c-SIA, and the patterns of their potential interaction.
Exogenous administration of anandamide and Clonidine together, before or after stress exposure, increased c-SIA even with differences in the time of manifestation of the effect, its duration and the degree.
The two systems differently contribute to c-SIA pathogenesis and mediation. Administered before stress exposure cannabinoids and the adrenergic system seem to oppose each other: the latter rather potentiates, while cannabinoids suppress c-SIA. Administered after stress exposure, instead, the two systems appear to exert a synergistic effect, and antagonization of each one of them abolishes the analgesic effect.
Portfolio Optimization and Asset Pricing Implications under Returns Non-Normality Concerns

Published: March 2022

Nous étudions les implications de la non-normalité pour l’allocation d’actifs et la tarification. La non-normalité des rendements des actifs est capturée par un modèle normal-exponentiel multivarié ; nous développons une procédure d’estimation basée sur une méthode des moments généralisée. Les préoccupations de non-normalité des investisseurs sont introduites en ajoutant une contrainte de non-normalité linéaire à un cadre moyenne-variance par ailleurs standard. La solution du portefeuille optimal est obtenue sous forme fermée et peut être reformulée comme une stratégie de séparation à trois fonds. Des portefeuilles sous-optimaux qui ignorent la non-normalité ou sont naïfs en termes de diversification peuvent entraîner des coûts de bien-être importants mesurés par l’équivalent certain, notamment pour les investisseurs les plus tolérants au risque qui ciblent des ratios de non-normalité élevés. À l’équilibre, les rendements attendus admettent une représentation à deux bêta dans laquelle le bêta le plus important pour expliquer leur variation transversale est celui capturant la non-normalité (plus de 60 %) tandis que le bêta du MEDAF explique moins de 12 %.
Reusing Existing Infrastructure for CO2 Transport: Risks and Opportunities
Authors: Luna-Ortiz Eduardo 
Published: March 2022

AbstractThere is no doubt that greenhouse gas emissions, particularly CO2, needs to be reduced to mitigate the effects of climate change. While carbon management can be achieved through a number of technological and engineering approaches ranging from energy efficiency (i.e., highly energy integrated system and process intensification) to renewable energy (wind, solar, hydrogen), CO2 capture & storage (CCS) has been identified as having a key role in the energy transition.Captured anthropogenic CO2 can be permanently stored in saline aquifers and depleted reservoirs. Saline aquifers (normally unsuitable for industrial or human exploitation) offer the largest storage capacity; however, there is, usually, lack of geological characterization leading to high risks due to large uncertainty. On the other hand, depleted gas fields, close to economical life cessation, are deemed an excellent alternative as safe and long-term storage is already proven and immense geological characterisation has been gathered during production life. Moreover, there is great potential to repurpose the existing offshore infrastructure (pipelines, platforms, and wells) as to minimize capital expenditure and delaying decommissioning costs. Repurposing existing production systems can also be an efficient way to achieve rapid deployment of CCS at large scale.In this paper, we present the key engineering challenges, risks, and opportunities in the re-use of existing oil and gas offshore infrastructure for CO2 transport and injection. We highlight the complex operational constraints and interactions between different components of the transportation network. The design and operation of the transportation network is governed by the following drivers:Safe design Robust and flexible operation Minimize cost (or delay expenditure as long as possible) Minimize emissions of greenhouse gases associated to the operation of the transport network (i.e., energy efficiency) Start operation with minimum modifications
Assessment of Machine Learning Techniques for Real-Time Prediction of Equivalent Circulating Density
Authors: Roy Vishnu , Pandey Anurag , Saxena Amit , Sharma Shivanjali 
Published: March 2022

AbstractThe equivalent circulating density (ECD) is crucial in avoiding fluid losses or kicks while drilling. It's more critical in wells where the pore pressure gradient is close to the fracture pressure gradient. The conservation of mass and momentum determine the ECD, but this method does not account for other factors like torque, rotating speed, weight on bit, etc. These may affect the ECD directly or indirectly. The aim of this study is a practicality to predict the ECD using various machine learning techniques and to determine their effectiveness.The complete drilling dataset of an oil well from Texas was acquired. Over 16000 data points were obtained after the removal of the null values. The data was prepared by scaling it and conducting principal component analysis (PCA). PCA reduced the dimensionality of the dataset while retaining the information. Following this, five different machine learning regression techniques were used to predict the equivalent circulation density, namely, XGBoost, Random Forest, Support Vector Machine, Decision Tree, and Elastic net regression. The performance of these techniques was judged by comparing their R2 scores, mean squared errors (MSE), and root mean squared errors (RMSE).The results showed that ECD prediction through all the above machine learning techniques is a vital reality. Random forest regression emerged superior from the different methods used, illustrating the highest R2 score and the lowest MSE and RMSE. Its R2 for our model was 0.992, which is an excellent fit. It was followed by SVM, which had the second-lowest RMSE and an R2 of 0.987, close to the random forest technique. Elastic Net, Decision tree, and XG Boost in the respective order were at the bottom of the pool.Machine learning is a powerful tool at our disposal to effectively predict quantities in real-time that directly or indirectly depend on several parameters. It can even be effective when no direct correlation between the quantities is known. Thus, machine learning can significantly enhance our ability to optimize drilling operations by having quicker and more accurate predictions. The work shown in this study, if implemented, can provide the crew more time to respond to situations such as the occurrence of kicks and thus will lead to safer operations.
Mitochondrial and Nuclear DNA-based Identification of Some Forensically Important Calliphoridae (Diptera) in Luoyang of China
Authors: Yang Mengzi , Zhang Weiping , Tuerxun Adilai , Mo Yaonan , Zhai Xiandun 
Published: March 2022

Introduction:

Calliphoridae plays a key role in forensic entomology research, which is one of the first insects to decompose animal carcasses. The mitochondrial cytochrome c oxidase subunit I and the ribosomal internal transcribed spacer 2 (ITS2) are among the most widely used molecular markers for insect taxonomic characterization.

Aim:
The aim of the study was to test the suitability of two genetic markers based on conducting the molecular identification of six necrophagous Calliphorid flies.

Materials and Methods:
Fourteen Calliphoridae flies were collected and classified with traditional morphological characteristics. The DNA of flies was extracted and the fragments of COI and ITS2 were amplified and sequenced. All the sequences were aligned and analyzed by MEGA 7 software for NCBI BLAST, nucleotide composition, intra- and inter-specific divergence calculation, and phylogenetic tree inference successively.

Results:
The results indicated that COI and ITS2 genes were robust in the identification of Calliphoridae at the species level and ITS2 gene sequence possessed a strong resolution power as it showed higher variation values between Lucilia sericata and Lucilia cuprina, Calliphora vomitoria and Triceratopyga calliphoroides, C.vomitoria and Aldrichina grahami, but inferior to COI for T. calliphoroides and A. grahami.

Conclusions:
Our results showed that combination of COI + ITS2 genes yields more accurate identification and diagnoses and better agreement with morphological data than the mitochondrial barcodes alone. As a supplementary method for morphological identification, we advocated for the combination of nuclear and mitochondrial gene approaches to address the taxonomy and phylogeny of forensic relevant flies, especially of closely related species and populations.

Quarantine, an unpleasant experience, was implemented in many countries to limit the spread of Coronavirus disease 2019 (COVID-19), which it could associated whit lifestyle changes. The present study aimed to determine the changes in Iranian's lifestyle during COVID-19 pandemic.

Materials and Methods:
In the present cross-sectional study, 2710 Iranian people completed an online researcher-made questionnaire asking lifestyle regarding COVID-19, which includes five sections about physical activity, stress and anxiety, nutrition habit, sleep disorders, and interpersonal relationship in addition to demographic data from January to February 2021, using the multistage cluster sampling method.

Results:
The participants’ mean age was 33.78 ± 11.50 years and 68.3% of them were female. Traveling, sightseeing, and family visits have been eliminated from 91%, 83.5%, and 77.5% of participants’ lives, respectively. There were increase in stress level (P < 0.001), weight of the participants (P < 0.001), sleep problems (P < 0.001), and healthier foods (P < 0.001) but decrease in interpersonal communication (P < 0.001) and the amount of physical activity (P < 0.001).

Conclusion:
In summary, this study indicates some changes in lifestyle of Iranian people, including changes in some eating practices, physical activity, social communication, and sleeping habits during the pandemic. However, as the COVID-19 pandemic is ongoing, a comprehensive understanding of these behaviors and habits can help develop interventions to mitigate the negative lifestyle behaviors during COVID-19 pandemic.
Metabolic effects of adding Topiramate on Aripiprazole in bipolar patients aged between 6-18 years, a randomized, double-blind, placebo-controlled trial
Authors: Arman Soroor , Haghshenas Mostafa 
Published: March 2022

Background:
second-generation antipsychotics (SGAs) are associated with metabolic side effects in child and adolescents. The aim of this study is to evaluate the metabolic effects of adding topiramate on aripiprazole in patients with bipolar disorder (BD) aged between 6 and 18 years.

Materials and Methods:
A 12-week, double-blind, placebo-controlled, randomized trial was conducted in the child psychiatric units of university hospitals. Forty patients aged between 6 and 18 years with new diagnosis of BD participated in the study. Eleven patients were excluded. Subjects received aripiprazole plus topiramate (Group 1, n = 15) or aripiprazole (Group 2, n = 14) for a 3-month period. Young mania rating scale (YMRS) was used for measuring the manic symptoms severity. Primary outcome measures included weight, height, body mass index (BMI), waist circumference, abdominal circumference, and blood pressure. Secondary outcome measures included fasting blood glucose, hemoglobin A1C, fasting insulin, and fasting lipid profile. Changes in metabolic profile during the study were obtained by using repeated measures of variance.

Results:
During a 3-month follow-up, YMRS measures decreased significantly in both groups with a significant difference between groups (P < 0.05). The mean of weight, BMI, and high-density lipoprotein levels in group 2 were significantly increased (P < 0.05), and the mean of low-density lipoprotein level in group 1 was decreased (P < 0.05). No significant differences were observed in anthropometric parameters and metabolic indices between groups (P > 0.05).

Conclusion:
Adding topiramate on aripiprazole is effectivefor controlling bipolar disorder as well as metabolic adverse effects of SGAs in juvenile patients.
Character as social semiotic in Wole Soyinka’s The lion and the jewel
Authors: Iroegbu Obinna 
Published: March 2022

Semiotics is context bound. Therefore, it is appropriate to situate the locale of any interpretation of art as veritable vehicle for proper understanding. In this regard, Wole Soyinka’s The Lion and the Jewel as a dramatic text derives a better metaphorical essence when assessed as a semiotic correlative of the socio-political conditions in the Nigerian post-colonial experience. Beyond its engagement in the dramatization of events that constitute narrative, character plays a pivotal role as a means by which thematic concerns can be mirrored. In other words, in all ramifications of its application, character usually plays representative roles, especially considering the fact that fiction aims at reflecting what is obtainable, probable or conceivable in a given context. Relating the dramatic events that played out in the text, it is observed that The Lion and the Jewel in its characterization captures a proper representation of socio-political personalities in Nigeria, including the author, Soyinka. From the jewel of contest which is the political power to the predatory turncoats who plunder and rape the patrimony, the drama demonstrates how character can assume a mimetic essence that indicates prophetic act. Just as it is common practice to tag an overbearing political leader the Orwellian Big Brother, and considering how the drama has succeeded to relate or relay socio-political identities, it is duly recommended that examination of characters in literature, especially African literature, should account for their roles as counterpart identities of politically exposed persons. Thus, there is a Baroka in the politician who snatches power by unorthodox means; a Lakunle in the upstart whose feeble attempt to contest political power is laughable and a Sadiku who is an accomplice in spite of being a victim.

Authors: Ogah Abari Ijuo , Abutu Dennis Oche 
Published: March 2022

The act of persuasion in advertising and the business world have become one of the most crucial elements in marketing communication. Advertising your business is therefore rooted in the ability of communication experts to come up with messages capable of persuading potential customers and clients to purchase the organization’s products. This implies that, messages that lack persuasion will hit only on deaf ears and the goal not attained. Accordingly, this paper centered on the theoretical analysis on persuasive communication in advertising and how they can be applied in marketing communication. The paper employed secondary data collection method, which is centered on compiled literature and researches relevant to this work. The paper positioned that persuasive communication employs the marketing mix as avenue of reaching potentials customers. The paper was further moored on common persuasive techniques such as plain folk testimonials, hidden fear appeals, social status approach and bandwagon effect. The paper was further anchored on four persuasive theoretical underpinnings that can be applied for effective marketing communication. These include the Persuasion theory, the AIDA model, Elaboration likelihood model and the Fogg Behavioural model. The paper conclude that, arketing communication thrives on persuasion and any advertising message without persuasive elements will yield no result as persuasion is the moving force of marketing communication. Lastly, the paper amongst other points recommends effective use of communication strategy designed to convince consumers, utilization of various media that meet the audience needs and to bridge the knowledge and action gap in the marketing process.

Published: March 2022

This study seeks to dilate the professional enterprise of Onyema Ugochukwu, one of the most respected practitioners and influencers of contemporary media practice and specialised journalism in Nigeria. It investigates his professional background as an economist and banker, through his detour into the media as progenitor of a new genre of technicalized reportage, and a seasoned manager in one of Nigeria’s most important newspapers in its time, the Daily Times of Nigeria Plc. It also scrutinises his later undertakings in political communication and public information management in his polyvalent media career over a period of five decades. Deploying the historic-method, this article probes the career course of Ugochukwu as a reporter, writer, editor, editorial director, political publicist and presidential communicator. This is to appropriately define his contributions to these aspects of the gamut of media practice, and to national growth. It successfully establishes that Ugochukwu has contributed immensely to the elevation and standardization of media practice and its repositioning as a profession which commands scholarship and intellectualism in the furtherance of national development.
