Speaking Truth to Power: Mental Health Service Users’ Experiences of Participation in their Diagnosis and Treatment
Authors: Kirwan Gloria
Published: October 2021

In a qualitative study, long-term mental health service users shared their views on the concept of ‘participation’ as shaped by their personal histories of contact with mental health services in Ireland. Adopting a narrative methodology, the study participants were asked to draw on their experiences with mental health services to illustrate their general views on participation by service users in mental health care contexts.In this study, the research participants recounted positive experiences of participation in which their expressed views regarding their symptoms and treatment needs were incorporated into the service responses they received. The data revealed that service users perceived open and inclusive communication by service providers as an important factor in optimising their ability to participate in help-seeking, diagnosis and treatment plans. However, the study also illuminated the chilling effect on participation when service users’ views were not heeded or acknowledged by service providers. The findings highlight how the failure to include service users’ insights can negatively encroach on service user participation. The service user narratives collected in this study exposed the often uneasy juxtaposition of the service user’s personally held ‘truth’ regarding their lived experience of mental distress versus the powerful system of expert diagnosis and treatment. This article focuses on reporting selective findings from the study regarding participation in the contexts of help-seeking, diagnosis and treatment decisions.
Hiding and being hidden: The marginalisation of children’s participation in research and practice responses to domestic violence and abuse
Authors: Eliffe Ruth , Holt Stephanie , Øverlien Carolina
Published: October 2021

his group is known within the literature to be a hard to reach population. This is namely due to their perceived vulnerability, as well as efforts to protect them by adult gatekeepers, and rigorous ethical procedures that make recruitment efforts often challenging. Consequently, this group, sometimes for their own protection, remain hidden in the shadows when it comes to research and practice responses that continue to operate from an adult-centric lens when children’s agency is not fully acknowledged. This paper sets out to discuss the multiple ways by which children who experience domestic violence both hide and are hidden by adults, rendering them invisible. Based on findings from a qualitative doctoral study that sought to explore children’s experiences of the police response to domestic violence, this paper highlights the interconnectedness between children’s invisibility in practice and research, and the processes through which they become and can remain hidden in these two arenas. The paper calls for a need to bring children’s experiences of domestic violence out of the shadows and to begin to acknowledge their agency and capacity as both research participants and victims.
‘They’re trying to teach them what I can teach them at home, and them not a Traveller!’: Introducing Irish Traveller identity into the curriculum
Authors: Cavaliero Tamsin
Published: October 2021

This paper documents research that investigated Irish Traveller women’s experiences of education within the context of a rapidly changing society. The paper discusses the methodological approaches chosen by the researcher in order to support research with hard-to-reach populations (Sydor, 2013). The findings detail the complexities surrounding the introduction of Traveller identities into the curriculum. The paper concludes with a discussion of need for a change in practice and understanding which values collaboration between Traveller communities and educational environments thereby benefitting Irish Traveller women who are the key actors in Traveller children accessing education and thereby improving educational outcomes and subsequent life chances.
Just shut up and let them talk’: Participation, power and the parent voice in the child protection system
Authors: Gibbons Marie , Connolly Nuala
Published: October 2021

Participatory practice is acknowledged as increasingly important in empowering families in the decision-making process. Yet parental participation in child protection and welfare settings remains a complex and multi-dimensional practice, dependent on a range of individual factors including willingness to engage; understanding of need, as well as system factors including power dynamics and resource constraints (Darlington et al., 2010). Parents can feel ‘powerless and helpless’ when not involved in decision-making processes (Hardy & Darlington, 2008). In addition to practice wisdom emerging from literature in the field, this paper examines the findings of a research study commissioned by Tusla (the Irish, national, statutory Child and Family Agency) on parental experiences of Child Protection Conferences (CPCs) in Counties Galway and Roscommon. Analysis of findings of a series of qualitative interviews (n=14) with parents who have attended CPCs, found that parents in the study felt unprepared for CPC, unclear of the implications for their families and felt marginalised by the CPC process. While many parents recognised their right to reply, most reported wanting to appear cooperative. The paper proposes recommendations including the development of a protocol for CPC preparation; participation supports for parents to ensure their voices are heard throughout the process; debriefing as a structured phase of the CPC; and continuous intensive engagement with parents post-CPC.
Support-nets: A participative Action-research into the Value of a Mutual Support Group to overcome Social Isolation.
Authors: Zwijnenburg Jenny , Van Regenmortel Tine , Schalk René
Published: October 2021

Social isolation is a widespread problem with which community oriented social workers are increasingly confronted. Mutual support groups can be used by social workers to support socially isolated people. This paper reports on a participatory action research into the method Support-nets. In this method, a mutual support group is set up specifically for people that share the problem of social isolation. The aim of the study was to gain insight in how participants and social workers give substance to mutual support to overcome structural social isolation. Results show that in a Support-net, every participant is enabled to actively contribute. This makes participants feel that they are valued members of a social group. Based on this shared identity, people offer each other different types of social support, thus alleviating their isolation.
Shifting roles of Employers: At the Intersection of Employment and Social Work: A case study from Norway
Authors: Breimo Janne Paulsen , Anvik Cecilie , Olsen Terje
Published: October 2021

Active labour market policies (ALMPs) are often seen as a panacea for dealing with labour market exclusion, especially when it comes to young people with mental health issues. Such policies demand considerable involvement from employers, placing more responsibility in their hands. Yet, there remains a notable knowledge gap concerning the actual role that employers play in processes of inclusion in the labour market. In this article, we provide knowledge about what employers do in order to include young people with mental health issues into the workforce, what roles they play in these processes, and what motivations underlie their endeavours. We argue that, due to organizational changes to occupational rehabilitation in Norway, employers must increasingly occupy a vacancy left open by social workers. While this situation has demanded further responsibility from employers, they are quite often insufficiently educated or trained to deal with such issues.We address what consequences this could have for young people with mental health issues striving to enter the labour market.

Nexus Between Technological Innovation and Economic Growth: Evidence From Nigeria (1980-2018)
Authors:   Nile University of Nigeria, OYEGOKE Ebunoluwa , ARAS Osman Nuri ,   Nile University of Nigeria
Published: October 2021

Technological innovation in developing countries is inherently identified with the transfer of technology from the advanced country via trade, FDI and importation of capital and intermediate goods, machinery and other forms of embodied technology (ETC). This is due to low investments in in-house research and development (R&D) activities by local producers, hence, the need for technology transfer and spillover. This study contributes to existing knowledge by examining the empirical short-run and the long-run relationship between technological innovation and economic growth, a case study of Nigeria using the ARDL model on annual time series data spanning from 1980-2018. The f-bound cointegration test shows a long-run relationship among the variables at 5% significant level. Overall, is the results show a positive relationship between innovation in the form of technology transfer and spillover, and economic growth at 5% level of significance. Based on these findings, we propose that technological innovation should be encouraged; however, in-house innovation activities (R&D) should be encouraged due to its peculiarity to the economic structure of the country.

Researching the tourist attractions and the attractiveness of the valley of the river Mreznica
Authors: Knežević Rade
Published: October 2021

The River Mreznica (64 km) is a watercourse in the region of Central Croatia. In the valley of the Mreznica, the forms of the relief created by erosion and deposits present an important basis for tourism development. This paper explores their appeal (attractiveness). In terms of tourism, about 10 per cent of the direct resources have already been valorised, while the remaining resources represent potential tourist attractions. The real tourist attractions are located in the lower valley, whereas the potential attractions are found in the middle and upper river valley. Access to potential attractions and their valorisation in tourism is impeded by the spreading of the underbrush, which has advanced considerably over the past twenty years, and by the fact that the upper valley is located in the zone of the “Eugen Kvaternik” Military Polygon. Travertine barriers, which have created a specific type of waterfalls and cascades, together with mills, bridges and ferries, characterise the tourist attractions in the valley of the River Mreznica.
Što je to postimperijalna suverenost? Uz Nomos zemlje – Carl Schmitt i kritičko čitanje Hanne Arendt
Authors: Paić Žarko
Published: October 2021

Autor u članku analizira Schmittov spis Nomos zemlje postavljajući pitanje na koji se način nakon epohe nacije-države i kraha europskoga imperijalizma, što je bila i ishodišna postavka Hanne Arendt u njezinim Izvorima totalitarizma, uspostavljaju uvjeti mogućnosti političkoga djelovanja, budući da to djelovanje više nema za svoj egzistencijalni prostor ideju ukorijenjenosti u naciju kao državu s mehanizmima zaštite suverenosti s pomoću zakonodavne, izvršne i sudske vlasti zapisane u ustavu. Moć nije pritom tek državno-društvena logika upravljanja fiksnim prostorom i ograničenim teritorijem nacije-države, kako je to bilo uobičajeno od 18. stoljeća u Europi do kraja I. svjetskoga rata. Sam je Schmitt u drugome razdoblju njegova filozofijsko-pravnoga mišljenja, formalno i sadržajno nakon kraja II. svjetskoga rata, političko i politiku sagledao kao univerzalnu geopolitiku “velikoga prostora” (Großraum). Egzistencijalno- decizionistički obrat pokazuje se odlučujućim razlogom zbog čega se Schmittov pojam političkoga ne može proglasiti opravdanjem bilo kakve diktature ili totalitarizma. Odluka počiva na praznom središtu slobode, a ne moći. Nomos zemlje u postnacionalnoj konstelaciji za Schmitta na taj način postaje pitanje poretka i uprostorenja u osvajanju i prisvajanju zemlje u stalnim ratovima i sukobima s Drugim, jer je čovjek sve drugo negoli po prirodi dobar. Kritika ove pozicije u marginalijama Hanne Arendt uz Schmittovu knjigu Nomos zemlje otvara mogućnost rasprave o granicama neoimperijalizma i nove pravno-političke konstitucije svijeta nakon II. svjetskoga rata. Autor smatra da je rezultat ove aporetične i paradoksalne situacije u 21. stoljeću upravo u tzv. postimperijalnoj suverenosti kao nastavku Schmittove postavke o izvanrednom stanju na globalno-planetarnoj razini. Političko otuda prethodi politici kao što novi nomos zemlje zahtijeva obrat u razumijevanju odnosa slobode i moći.
Stavovi stručnjaka/inja o politici regulacije prostitucije u Hrvatskoj
Authors: Krnić Rašeljka , Adamović Mirjana , Radačić Ivana
Published: October 2021

Različite ideološke pozicije određuju modele, odnosno politike usmjerene prema reguliranju prostitucije, tj. prema osobama koje se prostitucijom bave, organiziraju prostituciju ili traže usluge u toj domeni društvenog života. U ovom radu prikazujemo stavove relevantnih stručnjaka/inja o politikama prostitucije u Republici Hrvatskoj. Rezultati rada temelje se na kvalitativnom istraživanju provedenom polustrukturiranim intervjuima na uzorku 15 stručnjaka/ inja iz različitih područja (ministarstava, vladinih ureda, neovisnih državnih tijela, saborskih odbora i civilnih udruga) u čijem je djelokrugu regulacije fenomen prostitucije ili s njim povezani problemi. Sugovornici/e prostituciju najčešće smještaju ili u diskurs nasilja i eksploatacije ili u diskurs seksualnog rada. Većina stručnjaka/inja zagovara promjenu modela regulacije prostitucije, a među najčešće spominjanim europskim modelima, na koje bi se hrvatski model mogao ugledati, su švedski model kriminalizacije klijenata, dekriminalizacijski model i model legalizacije. Primjetno je da se stručnjaci/kinje iz civilnog društva koji donose programe smanjenja štete i rade s osobama koje prodaju seksualne usluge češće opredjeljuju za liberalne modele reguliranja prostitucije. Svi stručnjaci/kinje ističu važnost donošenja politika koje bi bile usmjerene prema lakšem izlasku iz prostitucije.

Special attention is paid to analyzing the Ministry of Education and Science of Ukraine Standard on speciality 254 “Support of the Army (forces) for the first (bachelor’s degree) level of higher education”. The article highlights the outcomes of a pilot research on the basis of: the “Psychogeometrical test” projective methodology, the “Leader” test, and the authors’ questionnaire to determine the leadership potential. On the outcomes of analyzing the respondents’ answers, a low level of leadership potential development was determined, which attests to an insufficient communication level, cadets’ narrow world outlook on various issues, passivity, lack of skills in and unwillingness to demonstrate persistence. By 95 % of respondents’ answers, the importance of studying leadership disciplines at a military institution of a technical higher education establishment has been proved. The professional training improvement for future officers-leaders has been substantiated in the article.
FORMATION OF LEADERSHIP QUALITIES IN FUTURE OFFICERS OF THE NATIONAL GUARD OF UKRAINE
Authors: Lebedyk Lesya , Strelnikov Viktor
Published: October 2021

The article deals with the search for a new understanding of the essence of the phenomena of “leadership” and “leadership qualities” and the theoretical foundations of leadership development through an individual approach to the training of future officers of the National Guard of Ukraine. It is proposed to include the integration of individual training in the professional activities of future military leaders, consistent with the strategic direction of the National Guard of Ukraine. It is determined that the preparation of future officers for leadership in the military team is a socio-pedagogical system that helps cadets to master three basic leadership skills: diagnosing the development of subordinates, flexibility and partnership. Through the organization of individual training of officers-leaders, three more basic leadership skills “in themselves” are developed - to challenge the accepted limitations, to determine the levels of their power and to cooperate for the sake of success. It is proved that effective development of leadership qualities should take place at all four levels: self-management; individual subordinates; military unit (team) and military organization.

Optimization of Coating Process from Cermet Powders by Plasma Spraying in Air
Authors: Okovity V. A. , Panteleenko F. I. , Okovity V. V. , Astashinsky V. M.
Published: October 2021

The paper presents studies on the optimization of the process of applying coatings from cermet powders with different solid phase contents by plasma spraying in air to restore and harden parts of machines and mechanisms operating under adverse conditions. Such conditions are usually created in heavily loaded tribojoints when the mechanisms operate at a low speed of relative movement of surfaces during friction. At the same time, the destruction of the working surfaces is mainly due to the process of microcontact setting and subsequent detachment of the formed particles at their contact points. The application of special protective coatings with the required properties is possible with the manufacture of high-quality starting powder materials and optimization of the technology for their application. Such powders and powder compositions can be obtained by the method of agglomeration of a fine powder mixture with its subsequent high-temperature sintering. To identify the hardening mechanism of composite coatings made of cermet by gas-thermal spraying, important stages are the optimization of the deposition process parameters and the study of the properties of plasma coatings obtained in this case. When optimizing the technological parameters of plasma spraying of coatings, the utilization rate of the sprayed powder material has been taken into account as the main indicator of the process efficiency, the structure of the obtained layers, and the morphology of individual particles deposited on the polished surface. The paper provides data on the structural elements of sprayed materials for wear-resistant coatings obtained by plasma spraying at optimal conditions. Taking into account the processes that occur during the wear of tribological conjugations, the data indicate the existing prerequisites for the wear resistance of the studied composite coatings made of metal ceramics. Special wear-resistant coatings made of materials with a soft matrix hardened by solid inclusions Al2O3–TiO2–Ni–Cr–Al–Y are widely used in various industries. Based on the detailed analysis of the features of cermet plasma coatings, it can be stated that such powder compositions (complex oxides-metal component) are often used as wear-resistant plasma coatings. The research results can be taken into account in cases of application of wear-resistant plasma coatings made of metal-ceramics and compositions based on them, containing solid phases in the form of oxides, as well as the manufacture of a whole range of parts operating under conditions of intense wear.
Thermodynamic Estimation of the Parameters for the C–H–O–N–Me-Systems as Operating Fluid Simulants for New Processes of Powder Thermal Spraying and Spheroidizing
Authors: Gorbunov A. V. , Devoino O. G. , Gorbunova V. A. , Yatskevitch O. K. , Koval V. A.
Published: October 2021

Over the past few years, a group of new processes was developed for high-temperature, including plasma electric arc spraying (at ambient pressure) and spheroidizing of some ceramic and metal powder materials with the use of gaseous hydrocarbons in the heat carriers as well as with feeding of organic additions into a high-temperature jet, in particular, polymeric ones, to control porosity of sprayed metallic functional coatings. The paper considers the possibility to modify such technological processes by introducing solid fuel additions of a polymer type into the operating fluid of an apparatus for gasthermal (plasma or other) treatment, which provides melting of metal or oxide powders. For this, with the help of thermodynamic analysis, the processes have been evaluated at temperatures (300–3000) K for the set of such reacting five component systems as C–H–O–N–Me (at ambient pressure 0.101 MPa) with five variants of Ме – aluminum, titanium, chrome, copper, nickel. This makes it possible to consider these systems as simulants for potential technologies for the treatment of oxide powders (Al2O3, TiO2, Cr2O3) as well as metallic ones (Cu, Ni and their alloys). In order to obtain high exothermic contribution to the heating of powders, the combination “air + polymeric addition (polyethylene) of LDPE grade” was chosen as mixed heat carrier (operating fluid) for the basic version of simulated process. During the analysis of equilibria for the considered multicomponent systems (17 variants), a set of following parameters has been used to characterize the energy intensity of the target powder heating process: the equivalence ratio for reacting mixture and its adiabatic temperature; the energy efficiency of material heating with and without taking into account the effect of fuel addition; specific energy consumption for the powder melting; autothermicity degree of the process during the combined heating (electrothermal heating by the arc of plasma torch and heat flux from the “air + solid fuel additions” mixture) of refractory powders. As a result of the assessment, the preferred (from thermodynamic standpoint) regimes of the considered processes have been found and the possibility to realize an energy-efficient heating of these oxide and metal materials (without oxidation of the latter to CuOx, NiO) with a reduced part of the electric channel of energy transfer, resulted from the carrying out of appreciable effect of the fuel-initiated mechanism of heating in the analyzed C–H–O–N–Mesystems, has been shown in the paper.

A methodological method based on the use of the theory of preferred numbers has been proposed in order to improve the most important parameters of the working bodies of noise mufflers. As a result of many years of scientific research, the authors have established a previously unknown theoretical relationship between the main series of preferred numbers, golden ratio and Fibonacci series numbers. A new direction in the development of number theory has been considered in the paper, its classification has been compiled, including the geometric theory of numbers, preferred numbers, containing a new basic series of preferred numbers using the Fibonacci sequence. New formulas have been obtained to determine the denominators of geometric progressions for the series of preferred numbers and the area of a circle. Determining the area of a circle using the new formula allows to get more accurate values. A new formula for determining the circumference of a circle has also been derived. The designs of perforated partitions have been developed, in which the laws of the new basic series of preferred numbers are used. Determining the area of a circle using the new formula allows you to get more accurate values. A new formula for determining the circumference of a circle is also obtained. The designs of perforated partitions have been developed, in which the regularities of the new basic series of preferred numbers have been used. A calculated substantiation of the main geometric and structural dimensions of noise mufflers is given using a mathematical model of a perforated golden partition and new basic series of preferred numbers, which allow to obtain a noise muffler design that has the lowest possible aerodynamic resistance with the maximum possible reduction in the noise level of exhaust gases from internal combustion engines. An innovative model of a noise muffler for reciprocating internal combustion engines with improved hydraulic and acoustic characteristics based on the theory of numbers is proposed in the paper. The theory of preferred numbers applies to any technical device.

Authors: Rodríguez-Cuentas Grizel Karem
Published: October 2021

El cementoma gigantiforme familiar es una lesión fibro-ósea benigna poco común, que sigue un patrón de herencia autosómico dominante. Se presenta durante la infancia y se limita a los huesos de la cara, especialmente la mandíbula. Presenta crecimiento rápido e indoloro, y se expande considerablemente con el paso de los años. Está considerada entre los siete trastornos que afectan la fisonomía del esqueleto craneofacial. Radiográficamente, se produce en tres etapas de maduración, al igual que las displasias óseas: radiolúcida, mixta y radiopaca, y se describe como una masa lobular mixta, bien delimitada, que puede aparecer en ambos maxilares y provocar la expansión de corticales óseas vestibular y palatina/lingual, el desplazamiento y la retención de piezas dentarias. Este artículo tuvo el objetivo de realizar una revisión de la literatura más relevante para identificar las características clínicas, radiográficas e histopatológicas del cementoma gigantiforme familiar en los maxilares, además de mostrar las herramientas imagenológicas útiles para el diagnóstico y seguimiento de la lesión.

Published: October 2021

La secreción del cortisol salival (Corts) es un reflejo de la adaptación de los individuos a los estresores internos/externos, con varios factores involucrados: biológicos y sociales. El objetivo de este estudio fue realizar una investigación documental sobre las variaciones de la concentración del Corts en relación con las diferencias biológicas de sexo y socialización de género, en las diferentes etapas del desarrollo humano. Para la búsqueda de la evidencia científica se utilizaron Medline/PubMed y Google Académico. Se seleccionaron 20 artículos originales, en idioma inglés, publicados en el periodo 2010-2020, incluidos ensayos clínicos y estudios observacionales. La relación entre Corts y género se discutió históricamente considerando los aspectos evolutivos y biológicos; sin embargo, no puede explicarse como una visión causa-efecto. Depende de factores socioculturales únicos que, en periodos sensibles del desarrollo humano, alteran el eje hipotalámico-pituitario-adrenal y condicionan el afrontamiento del estrés.
Investigating the effect of temperature gradient on biogas production from pretreated maize straw and rice husk using multistage anaerobic bioreactor
Authors: Haider Syed Zeeshan
Published: October 2021

The share of biogas in renewable energy sources is increasing as variety of feedstocks are now used for biogas production among which lignocellulosic biomass is emerging feedstock that can be used after proper pretreatment under best suited temperature. Although lot of pretreatments and temperature combinations have been tested but still there is a gap that can be filled by the current study focused on the effect of the temperature gradient (mesophilic and thermophilic) on biogas production potential of maize straw and rice husk using a modified Gompertz equation. Pretreatment was done by using alkali (NaOH and Ca(OH)2) and acids (HCl and H2SO4) each at 2, 4 and 6%.The pretreatment of crop residue with 6% NaOH degraded lignin contents significantly. The pretreated crop residue was further used for biogas production. A multistage anaerobic bioreactor containing three diagonally inline reactors provided with one water bath connected to reactors for better utilization of energy was used for biogas production. The temperature of water bath was adjusted to that the first reactor achieved 37°C and 55 °C for different experiments. The working temperatures found to be 31-37°C and 46-55°C were achieved to maintain the internal temperature of the reactors within mesophilic and thermophilice temperature ranges, respectively. The 36 days incubation time was equally divided for three reactors. The biogas production rate was297 mL/g-VSadded and 244.07 mL/g-VSadded from maize straw and rice husk under mesophilic conditions, respectively. The results showed an increased biogas yield for both feedstocks under mesophilic conditions as compared to thermophilic conditions. The central reactor showed better production as compared to other two rectors in all experiments.

COVID-19 patients shed SARS-CoV-2 RNA in stool, sometimes well after their respiratory infection has cleared. In our benchmarking study, we recommend a standardized protocol for the preservation, extraction and detection of viral RNA from stool. This protocol includes a preservative, viral RNA extraction steps, and PCR-based quantification methods to maximize yield and detection of SARS-CoV-2 RNA. Our protocol takes advantage of commercially available reagents and equipment to maximize ease of access and consistency across studies. Additionally, we apply an attenuated bovine coronavirus vaccine as a spike-in control, and synthetic RNA standards to improve standardization and reliability of the assay. While we recommend both ddPCR and RT-qPCR-based assays, we acknowledge that ddPCR may be prohibitively expensive due to the necessity of specialized equipment and reagents. This protocol was developed with a focus on SARS-CoV-2 RNA, but may apply to other coronaviruses as well. We estimate that this protocol takes between 6 to 8 hours total to quantify the viral RNA load in a fecal sample.

Examining Diffusion and Convergence Processes of Three Road Safety Policies, 1964-2015
Authors: Nazif-Munoz Jose , Berg Axel van den , Quesnel-Vallée Amélie
Published: October 2021

Global convergence of public policies has been regarded as a defining feature of the late twentieth century. This study explores the generalizability of this thesis for three road safety measures: i) road safety agencies; ii) child restraint laws; and iii) mandatory use of daytime running lights. We analyze cross-national longitudinal data using survival analysis for the years 1964-2015 in 181 countries. Our first main finding is that only child restraint laws have globally converged; in contrast, the other two policies exhibit a fractured global convergence process, likely as the result of competing international and national forces. This finding may reflect the lack of necessary conditions, at the regional and national levels, required to accelerate the spread of policies globally, adding further nuance to the global convergence thesis. A second finding is that mechanisms of policy adoption, such as imitation/learning and competition, rather than coercion, explain more consistently global and regional convergence outcomes in the road safety realm. This finding reinforces the idea of specific elective affinities, when explaining why the diffusion of policies may or not result in convergence. Lastly, by recognizing fractured convergence processes, our results call for revisiting the global convergence thesis and reintegrating more consistently regional analyses into policy diffusion and convergence studies.

Published: October 2021

Recently with the advancement of high-throughput sequencing, gene regulatory network inference has turned into an interesting subject in bioinformatics and system biology. But there are many challenges in the field such as noisy data, uncertainty, time-series data with numerous gene numbers and low data, time complexity and so on. In recent years, many research works have been conducted to tackle these challenges, resulting in different methods in gene regulatory networks inference. A number of models have been used in modeling of the gene regulatory networks including Boolean networks, Bayesian networks, Markov model, relational networks, state space model, differential equations model, artificial neural networks and so on. In this paper, the fuzzy cognitive maps are used to model gene regulatory networks because of their dynamic nature and learning capabilities for handling non-linearity and inherent uncertainty. Fuzzy cognitive maps belong to the family of recurrent networks and are well-suited for gene regulatory networks. In this research study, the Kalman filtered compressed sensing is used to infer the fuzzy cognitive map for the gene regulatory networks. This approach, using the advantages of compressed sensing and Kalman filters, allows robustness to noise and learning of sparse gene regulatory networks from data with high gene number and low samples. In the proposed method, stream data and previous knowledge can be used in the inference process. Furthermore, compressed sensing finds likely edges and Kalman filter estimates their weights. The proposed approach uses a novel method to decrease the noise of data. The proposed method is compared to CSFCM, LASSOFCM, KFRegular, ABC, RCGA, ICLA, and CMI2NI. The results show that the proposed approach is superior to the other approaches in fuzzy cognitive maps learning. This behavior is related to the stability against noise and offers a proper balance between data error and network structure.
