Authors: Winckel Anne , Ollagnier Stéphane , Gabillard Santiago
Published: November 2021

Groundwater is an integral part of the water cycle and an essential resource for human use. This moving heritage must be protected and preserved sustainably through understanding of the physical and chemical functioning of aquifers, and by monitoring its quantity and quality. The ADES groundwater database, created for storing and making available groundwater data in France, is a freely accessible tool for water management and communication, with easy data availability and exchange. Data originate from different producers, which requires normalization and standardization of the system needs, to allow data integration and exchange. Shared data models were set up and the system is based on communal repositories of water points and hydrogeological entities. Nearly 102 million groundwater-quality data and over 17 million water-level data are currently available, covering almost 61,800 stations. ADES allows visualization of water level data in “real time" for about 1500 stations equipped with GPRS (General Packet Radio Service) technology; it provides, on a public website and via web services, public quantitative and qualitative data that can be searched with different criteria. Data can be visualised in graphical or tabular form, and downloaded with associated metadata.

Authors: Cvetković Vladimir M.
Published: November 2021

In different parts of the world, decision-makers and risk managers use specific and particularly complex disaster early warning and alert systems to protect people and their material goods from the harmful effects of various disasters in a timely, efficient and appropriate manner. However, concerning the level of scientific-technological and economic development of certain countries, such systems can differ in the many characteristics that make them more efficient in specific situations. Guided by this, the subject of the paper is reflected in the systematic identification, analysis, and classification of the best innovative solutions of early warning systems regarding their usability and efficiency. To find appropriate innovative solutions, it was performed a search of different electronic databases. The findings of this review showed that there is a huge potential for innovative solutions in the field of disaster early warning and alert systems.
Psychological distress and problem list among patients with advanced cancer: A comparative study of Indonesia and Taiwan
Authors: Huda Nurul , Shaw Malissa Kay , Lin Yen-Kuang , Yu Wei-Zhen , Chang Hsiuju
Published: November 2021

Background
We assumed that patients in a country with lower economic development will have more psychological distress and problems than an economically stronger country. Therefore, the aims of this study were to determine whether advanced cancer patients in Indonesia have more psychological distress and experience more problems contributing to distress than a similar group of patients in Taiwan. We also examined the determinants of psychological distress.
Methods
We conducted a secondary data analysis comparing the data from 286 Indonesian and 70 Taiwanese participants, focusing on distress score and the Problem List (PL) of the Distress Thermometer. Descriptive analysis, Chi-Square test, independent t-test, One-way Anova and multiple linear regression with enter method were applied to analyse the data.
Results
Overall, more Indonesian respondents experienced distress and had more problems across all PL domains than Taiwanese participants. Being an early adult, having problems with childcare, housing and transportation were associated with higher distress while a higher depression score and having stage 4 cancer demonstrated lower distress among Indonesians. For Taiwanese respondents, appearance, bathing/dressing and pain determined psychological distress.
Conclusions
Differences in the healthcare system, economic level, culture, gender and age influenced the problems experienced by patients. Finding from our comparative study provide important insight into understanding distress and PL among ACPs in economically advanced countries compared with economically weak countries. Future collaboration to deliver interventions considering cultural and healthcare system differences between two countries should be developed

Published: November 2021

The combined effects of the abiotic factors such as temperature and synthetic progestins on the biochemical and physiological performances of marine clam Ruditapes decssatus under sub-chronic conditions are poorly studied. Here, we investigated the effects of levonorgestrel (1000 ng/l) alone or combined with increasing temperature of 20, 24 and 28°C on the biochemical and physiological responses and the gonad histology of the clam (Ruditapes decussatus) for 28 days. Our results revealed that, in clams treated with levonorgestrel (LNG) alone, there was an impairment of the defense against oxidative stress related to the inductions of CAT, GST and PSH, a reduction in the lysosomal membrane stability, a physiological disturbance via an increase in the level of estradiol, a decrease in the number of gonad oocytes and a reduction in vitellogenin like protein. Furthermore, exposure to heat stress of 20°C, 24°C and 28°C, alone or in combination with LNG, enhanced SOD antioxidant activity which was ineffective in preventing lipoperoxidation and altered clam’s physiological processes of reproduction via dramatic reduction of gonad oocyte numbers and of vitellogenin like protein reserves. Overall, these findings can be taken as a warning sign of temperature and levonorgestrel progestin effect that can lead to effective changes in the structure and function of target vital organs, such as the gonads of the clam Ruditapes decussatus, and this may have implications for the whole organism and populations.

Published: November 2021

Purpose: The aim of this study was to evaluate the effect of a couple-coping intervention aiming to improve uncertainty tolerance in women diagnosed with breast cancer and their spouses on the patients’ mental adaption to their disease. Methods: The present study was conducted on 90 women with breast cancer referred to educational, medical and research centers in Urmia, IRAN, which 45 patients were randomly assigned to each treatment and control groups. Outcome measures were assessed at baseline and 6 weeks using short form mental adjustment to cancer (Mini-MAC) questionnaire. The intervention was performed in 6 group-based sessions consisting of patients and their spouses. Results: comparing the change from before to after intervention revealed that the effect of the intervention was significant in reducing hopeless-helpless (-5.42 ± 2.42 in intervention group VS -0.13 ± 0.46 in control group, P<0.001) and anxious preoccupation (-6.80 ± 2.87 VS -0.16 ± 0.82, P<0.001). It has also been significant in increasing fatalism (4.89 ± 2.09 VS 0.22 ± 1.24) and fighting spirit (3.58 ± 2.05 VS 0.11 ± 1.61). The effect of intervention on changing avoidance scale was not significant (P = 0.83).Conclusion: Couple-centered intervention program based on increasing uncertainty tolerance can be used to improve the situation in order to increase the patients' adjustment and it has an effective support for breast cancer patients in helping to cope with cancer.

Authors: Bedych T.V. , Shayakhmetov A. B. , Omarov M. S. , Isintayev T. I.
Published: November 2021

In residential and industrial premises, optimum conditions for human activity must be created. In areas without central heating supply, heating of a mobile living space is provided by solid fuel boilers. There may be fuel outages at a distance from an inhabited locality. Therefore, the purpose of the study is to create a heating system for a farmer’s house by using carbon-based fuel flexible materials and solar stations. Farmhouse heating system that heats mobile living quarters remote from power lines and communities through the use of carbon-based fuel flexible materials and solar stations is proposed by the authors. The technical result consists in that, in the claimed system, the heating device is a carbon-based fuel flexible material supplying electricity from the solar station. Carbon-based fuel flexible material is a thermal film (heating grid), which is made by interweaving longitudinal and transverse carbon filaments and, for safety reasons, covered with an electrical insulating material.

The burden of drug-related problems (DRPs) is becoming an issue of healthcare concern. It has been responsible for many intensive care unit (ICU) admissions and emergency department (ED) visits in Saudi Arabia. We aim to summarise available data on ED visits and ICU admissions linked to DRPs in Saudi Arabia and provide recommendations for preventive measures. A systematic search of the literature was conducted using PubMed and Google Scholar databases to identify eligible studies. The review included research on ED visits and ICU admissions linked to DRPs performed in Saudi Arabia from the database’s inception to January 2020. Study selection, data extraction and assessment were performed based on the Preferred Reporting Items for Systematic Review and MetaAnalysis (PRISMA) guidelines. The initial search of literature generated 267 articles. After the study selection, 15 articles met our eligibility criteria and were included in the review. The commonly implicated DRPs were adverse drug reactions, medication non-adherence, drug overdose and drug interactions. Central nervous system drugs and cardiovascular drugs were the most frequently involved drugs. Most of these visits resulted in moderate harm. The prevalence of DRPs associated with ED visits and ICU admissions is high in Saudi Arabia. Sixteen out of a hundred ED visits and ICU admissions are related to DRPs. Therefore, the Saudi government should implement interventions to improve the awareness of rational drug use in the general public.

World Health Organization (WHO) classified Nigeria as a hyper-endemic hepatitis B surface antigen (HBsAg) positive nation with prevalence ≥ 8%. This study intends to add information that could strengthen established database to improve awareness and prevention of hepatitis B virus (HBV) infection. We aimed to evaluate seroprevalence and trend of HBsAg among blood donors in Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Ogun State, Nigeria over a five-year period. Data from records of 7,102 individuals aged ≥ 20 years old who donated blood to blood bank in this hospital from January 2012 to December 2016 were analysed for gender, age, number of donors per year and HBsAg status. Data analysis was done with Statistical Package for Social Sciences software. P ≤ 0.05 was considered statistically significant. Males were in the majority (6,547 [92.2%]). Age 30–39 years old was the major group (3,052 [43.0%]). Pooled HBsAg seroprevalence was 486 (6.8%). Females had the highest HBsAg seroprevalence across board with highest rate of 10 (19.6%) in year 2012 and pooled prevalence of 73 (13.2%). Age group of ≥ 50 years old had highest HBsAg seroprevalence 39 (8.5%) while age group of 20–29 years old had least 128 (5.8%). Stratified HBsAg positivity decreased steadily from year 2012 to year 2016. This location was HBV intermediate-endemic. There were age, gender and yearly seroprevalence of HBsAg related trends which could be leveraged upon in finding effective preventive measures against the disease. We recommend mass vaccination by government against HBV infection in addition to provision of sensitive blood investigational equipment.

Published: November 2021

Elaboration of steps for the strategic management of environmentally sound business solutions is essential for achieving sustainable development goals in Ukraine. Although strategic directions for decarbonization of the transport sector have already been developed at the national level, effectiveness of sustainable decision-making is closely related to the greening initiative on the local level. The purpose of the paper is to form a framework of greening strategy and sustainable decision-making for transport companies that is based on the necessity to reduce emissions. The research findings are obtained using the systems analysis, SWOT analysis, and cost-benefit method. The paper proves that choosing biogas (methane) as a main transport fuel is a viable and cost-effective initiative and can be used as a financial ground for the company’s strategic formation process that involves both tactical and organizational dimensions. The analysis results also showed threats and opportunities for greening based on switching transport companies to biogas and requiring steps of governmental support in developing biogas station networks. According to the green course, this study also reveals the possibility of establishing strategic management due to an authority delegation map between services and top management of a transport company. The study has made it possible to improve strategic management of a transport company by developing an optimal scheme of interaction between stakeholders and departments in strategic leadership for greening.

‘Overuse-charge’ agricultural water price mechanism in groundwater overdraft areas
Authors: Xiqin Wang , Xinyue Zhang , Hao Chen , Ying Chen
Published: November 2021

The irrigation water price is an indispensable element for the modernization of agriculture and the realization of rural revitalization. As a pilot initiative for agricultural water price reform, Hebei Province has explored various effective patterns. This study analyzed 714 first-hand data points obtained from agricultural irrigation areas in Hebei Province. The ‘two lines and three grades’ water price policy is difficult to implement in practice. The ‘overuse-charge’ includes two levels of water use is standards, the water price and reward standards in each level are inconsistent, especially, actual irrigation water use is far more than Individual Allowable Water Volume (IAWV). Similarly, there is a negative relationship between irrigation water use and water fees at the critical point of IAWV, that is, the more water used, the less water fees are paid. The ‘one line and two grades’ water price policy is proposed. The water volume less than the irrigation quota should be purchased by the government or rewarded farmers; on the contrary, the water price should be increased. It is suggested to improve the installation of irrigation metering facilities, popularization of field water-saving technology and quota management in the groundwater water irrigation region.

Japanese Anime Fandoms in the UAE: An Exploratory Study on Media Accessibility, Habits and Cultural Perceptions
Authors: Tariq Urwa , Nesti Willard Sarah Laura
Published: November 2021

The satellite TV revolution in the United Arab Emirates (UAE) in the early 1990s precipitated the proliferation of foreign media broadcasts. Japanese anime dubbed into Arabic became the most-watched content in Emirati households, a trend that continues to date because the Japanese entertainment and digital media industry offers youngsters easy access to and diverse options for anime. This paper provides an overview and analysis of the growing popularity of anime fandoms in the UAE to ascertain the level of commitment, involvement and the moral perceptions of Emirati fans vis-à-vis Japanese pop culture. A focus group discussion was conducted in a leading UAE university among the otaku or aficionados of Japanese anime (males and females). The participant responses offered comprehensive insights into the fandom trends of the region and articulated interesting opinions on Japanese pop culture and digital media accessibility. Notably, the findings of this study suggested that the enthusiasm of this fan following is often obstructed rather than celebrated and thus cannot achieve its potential. Therefore, the study finally contemplates how Emirati otaku and their practices may be better supported in UAE.

The Collaborative Metadata Repository (CoMetaR) Web App: Quantitative and Qualitative Usability Evaluation (Preprint)
Authors: Stöhr Mark R , Günther Andreas , Majeed Raphael W
Published: November 2021

BACKGROUND

In the field of medicine and medical informatics, the importance of comprehensive metadata has long been recognized, and the composition of metadata has become its own field of profession and research. To ensure sustainable and meaningful metadata are maintained, standards and guidelines such as the FAIR (Findability, Accessibility, Interoperability, Reusability) principles have been published. The compilation and maintenance of metadata is performed by field experts supported by metadata management apps. The usability of these apps, for example, in terms of ease of use, efficiency, and error tolerance, crucially determines their benefit to those interested in the data.

OBJECTIVE

This study aims to provide a metadata management app with high usability that assists scientists in compiling and using rich metadata. We aim to evaluate our recently developed interactive web app for our collaborative metadata repository (CoMetaR). This study reflects how real users perceive the app by assessing usability scores and explicit usability issues.

METHODS

We evaluated the CoMetaR web app by measuring the usability of 3 modules: core module, provenance module, and data integration module. We defined 10 tasks in which users must acquire information specific to their user role. The participants were asked to complete the tasks in a live web meeting. We used the System Usability Scale questionnaire to measure the usability of the app. For qualitative analysis, we applied a modified think aloud method with the following thematic analysis and categorization into the ISO 9241-110 usability categories.

RESULTS

A total of 12 individuals participated in the study. We found that over 97% (85/88) of all the tasks were completed successfully. We measured usability scores of 81, 81, and 72 for the 3 evaluated modules. The qualitative analysis resulted in 24 issues with the app.

CONCLUSIONS

A usability score of 81 implies very good usability for the 2 modules, whereas a usability score of 72 still indicates acceptable usability for the third module. We identified 24 issues that serve as starting points for further development. Our method proved to be effective and efficient in terms of effort and outcome. It can be adapted to evaluate apps within the medical informatics field and potentially beyond.
Exploring Infant Fall Events Using Online Parenting Discussion Forums: Infodemiology Study (Preprint)
Authors: Cooray Nipuna , Sun Si Louise , Adams Susan , Keay Lisa , Nassar Natasha , Brown Julie
Published: November 2021

BACKGROUND

Falls represent the most common mechanism of injury requiring hospitalization among children under 12 months, and they commonly result in traumatic brain injury. Epidemiological studies exploring infant falls demonstrate the experienced burden, but they lack contextual information vital to the development of preventive interventions.

OBJECTIVE

The objective of this study was to examine contextual information for falls involving children under 12 months, using online parenting discussion forums.

METHODS

Online parenting forums provide an unobtrusive rich data source for collecting detailed information about fall events. Relevant discussions related to fall incidents were identified and downloaded using site-specific Google Search queries and a programming script. A qualitative descriptive approach was used to analyze the incidents and categorize contextual information into “precursor events” and “influencing factors” for infant falls.

RESULTS

We identified 461 infant fall incidents. Common fall mechanisms included falls from furniture, falls when being carried or supported by someone, falls from baby products, and falls on the same level. Across the spectrum of fall mechanisms, common precursor events were infant rolling off, infant being alone on furniture, product misuse, caretaker falling asleep while holding the infant, and caretaker tripping/slipping while carrying the infant. Common influencing factors were infant’s rapid motor development, lapses in caretaker attention, and trip hazards.

CONCLUSIONS

The findings define targets for interventions to prevent infant falls and suggest that the most viable intervention approach may be to target parental behavior change. Online forums can provide rich information critical for preventive interventions aimed at changing behavior.
App-Based Mindfulness Meditation for People of Color Who Experience Race-Related Stress: Protocol for a Randomized Controlled Trial (Preprint)
Authors: Ramos Giovanni , Aguilera Adrian , Montoya Amanda , Lau Anna , Wen Chu Yin , Cruz Torres Victor , Chavira Denise
Published: November 2021

BACKGROUND

People of color (POC) who experience race-related stress are at risk of developing mental health problems, including high levels of stress, anxiety, and depression. Mindfulness meditation may be especially well suited to help POC cope, given its emphasis on gaining awareness and acceptance of emotions associated with discriminatory treatment. However, mindfulness meditation rarely reaches POC, and digital approaches could reduce this treatment gap by addressing traditional barriers to care.

OBJECTIVE

This study will test the effectiveness of a self-directed app-based mindfulness meditation program among POC who experience elevated levels of race-related stress. Implementation outcomes such as treatment acceptability, adherence, and satisfaction will be examined.

METHODS

Participants (n=80) will be recruited online by posting recruitment materials on social media and sending emails to relevant groups. In-person recruitment will consist of posting flyers in communities with significant POC representation. Eligible participants will be block randomized to either the intervention group (n=40) that will complete a self-directed 4-week mindfulness meditation program or a wait-list control condition (n=40) that will receive access to the app after study completion. All participants will complete measures at baseline, midtreatment, and posttreatment. Primary outcomes include changes in stress, anxiety, and depression, and secondary outcomes constitute changes in mindfulness, self-compassion, rumination, emotion suppression, and experiential avoidance. Exploratory analyses will examine whether changes in the secondary outcomes mediate changes in primary outcomes. Finally, treatment acceptability, adherence, and satisfaction will be examined descriptively.

RESULTS

Recruitment began in October 2021. Data will be analyzed using multilevel modeling, a statistical methodology that accounts for the dependence among repeated observations. Considering attrition issues in self-directed digital interventions and their potential effects on statistical significance and treatment effect sizes, we will examine data using both intention-to-treat and per-protocol analyses.

CONCLUSIONS

To our knowledge, this will be the first study to provide data on the effectiveness of a self-directed app-based mindfulness meditation program for POC recruited based on elevated race-related stress, a high-risk population. Similarly, meaningful clinical targets for POC affected by stressors related to race will be examined. Findings will provide important information regarding whether this type of intervention is an acceptable treatment among these marginalized groups.

New Hermite-Hadamard type inequalities for m and (α, m)-convex functions on the coordinates via generalized fractional integrals
Authors: Kermausuor Seth
Published: November 2021

In this paper, we obtained a new Hermite-Hadamard type inequality for functions of two independent variables that are m-convex on the coordinates via some generalized Katugampola type fractional integrals. We also established a new identity involving the second order mixed partial derivatives of functions of two independent variables via the generalized Katugampola fractional integrals. Using the identity, we established some new Hermite-Hadamard type inequalities for functions whose second order mixed partial derivatives in absolute value at some powers are (α, m)-convex on the coordinates. Our results are extensions of some earlier results in the literature for functions of two variables.
On the domination polynomial of a digraph: a generation function approach
Authors: Alencar Jorge , de Lima Leonardo
Published: November 2021

Let G be a directed graph on n vertices. The domination polynomial of G is the polynomial D(G, x) =∑ni=0 d(G, i)xi, where d(G, i) is the number of dominating sets of G with i vertices. In this paper, we prove that the domination polynomial of G can be obtained by using an ordinary generating function. Besides, we show that our method is useful to obtain the minimum-weighted dominating set of a graph.

Published: November 2021

Abstract: Reactive distillation processes are very promising in substituting Sconventional liquid phase reaction processes. However this technology is not suitable for all kind of processes or types of reaction. Therefore, assessing the feasibility of these process concepts forms an important area in current and future research and development activities. The present paper focuses on the feasibility studies based on the construction of residue curve maps for the toluene methylation system. The RCMs were constructed and analyzed; it is concluded that the process of synthesis of xylenes when carried out in the reactive distillation column enhances the selectivity of the desired para isomer.

A Recent Progress in Performance and Property Improvement in Underwater Welding
Authors: Bakrewal Ayush
Published: November 2021

Abstract: Underwater welding is the process of connecting materials underwater in the presence of water. It is used to maintain and improve the structure in marine and offshore applications. It's utilized for underwater pipeline maintenance, submerged offshore oil drilling, and ship repairs. It can also be found in nuclear power plants and deep-sea mining. Underwater welding is divided into two categories dry welding and wet welding. Dry welding entails enclosing the weld zone in a hyperbaric tank filled with a gas mixture and welding at the prevailing pressure. Wet welding is a type of welding that uses waterproof electrodes and is done directly on the component to be welded. The major benefit of this welding is its simplicity and cost effectiveness, but we can't obtain high weld quality as easily as we can with dry welding. Dry welding, on the other hand, may provide high weld quality, but it is a time-consuming procedure that needs the welder to secure the region with the hyperbaric vessel, and it is also a costly method. Underwater welding has a number of issues, including bubble arc generation, cold cracking, microstructural deformation, and more. We attempted to bring together the most recent developments in the field of underwater welding. We've outlined several techniques that were used to improve welding characteristics as well as important issues that must be addressed. This review article may be used to figure out what measures need to be taken to enhance the underwater weld joint quality. Keywords: Underwater welding, underwater wet welding, underwater dry welding, hyperbaric vessel, underwater welding development
O corpo, a casa e a cidade: territorialidades de mulheres negras no Brasil
Authors: Manzi Maya , Anjos Maria Edna dos Santos Coroa dos
Published: November 2021

Este artigo apresenta uma discussão sobre a relação entre territorialidade e interseccionalidade com base na experiência da mulher negra brasileira, no decorrer do processo histórico que desencadeou uma longa trajetória de luta contra o racismo e o sexismo. Foi utilizada pesquisa bibliográfica e documental para discorrer sobre os territórios do corpo, da casa e da cidade, entendidos como espaços de opressão e de resistência. Essas categorias de análise têm recebido bastante atenção, especialmente dentro do movimento feminista negro, porém poucos estudos abordam de maneira explícita e aprofundada a relação entre interseccionalidade e territorialidade ancorada numa concepção ampliada do território que vai do corpo até a cidade. Pensar esses conceitos em conjunto e de forma multiescalar pode contribuir para dar maior visibilidade aos espaços de protagonismo das mulheres negras brasileiras na luta pela reparação, pelo reconhecimento e pelo direito de existir.
Narrar a Serra, imaginar as cidades: o recurso à ficção na pesquisa sócio-espacial
Authors: Matos Fontenele Camila
Published: November 2021

Este trabalho tem origem no contato com moradoras idosas do Aglomerado da Serra, em Belo Horizonte, no âmbito de uma pesquisa internacional em rede. Naquele contexto, o material de diversas entrevistas foi desconsiderado por não responder diretamente às questões levantadas. Proponho aqui um retorno a esse material com o intuito de investigar a maneira como a força de trabalho desse grupo de mulheres foi fundamental, tanto na articulação da própria sobrevivência como na formação daquele território. Em primeiro lugar, abordo a natureza de ficção presente nas narrativas das idosas como possibilidade de fabulação sobre a vivência delas na cidade e a prospecção de futuro. Sugiro que a ficção também integra aquelas narrativas socialmente legitimadas enquanto “verdade”, como é o caso da história oficial e do discurso das ciências. Nesse sentido, a ficção emerge como importante ferramenta no que se refere à autofabulação para as interlocutoras e ao questionamento e ao tensionamento do lugar de legitimidade dos discursos oficiais.
Non-Markovian wave-function collapse models are Bohmian-like theories in disguise
Authors: Tilloy Antoine , Wiseman Howard M.
Published: November 2021

Spontaneous collapse models and Bohmian mechanics are two different solutions to the measurement problem plaguing orthodox quantum mechanics. They have, a priori nothing in common. At a formal level, collapse models add a non-linear noise term to the Schrödinger equation, and extract definite measurement outcomes either from the wave function (e.g. mass density ontology) or the noise itself (flash ontology). Bohmian mechanics keeps the Schrödinger equation intact but uses the wave function to guide particles (or fields), which comprise the primitive ontology. Collapse models modify the predictions of orthodox quantum mechanics, whilst Bohmian mechanics can be argued to reproduce them. However, it turns out that collapse models and their primitive ontology can be exactly recast as Bohmian theories. More precisely, considering (i) a system described by a non-Markovian collapse model, and (ii) an extended system where a carefully tailored bath is added and described by Bohmian mechanics, the stochastic wave-function of the collapse model is exactly the wave-function of the original system conditioned on the Bohmian hidden variables of the bath. Further, the noise driving the collapse model is a linear functional of the Bohmian variables. The randomness that seems progressively revealed in the collapse models lies entirely in the initial conditions in the Bohmian-like theory. Our construction of the appropriate bath is not trivial and exploits an old result from the theory of open quantum systems. This reformulation of collapse models as Bohmian theories brings to the fore the question of whether there exists `unromantic' realist interpretations of quantum theory that cannot ultimately be rewritten this way, with some guiding law. It also points to important foundational differences between `true' (Markovian) collapse models and non-Markovian models.

Yeniçağa Gölü Kuzey Anadolu fay hattı kuşağının etkisiyle oluşmuş bir çukurluğun sonradan alüvyonlarla dolması sonucu meydana gelmiştir. Yeniçağa gölü derinliği 2 metreyi bulan Türkiye’nin en büyük turbalığını içermektedir. Yeniçağa gölü aynı zamanda ticari balıkçılık potansiyeli olan bir doğal su kaynağıdır. Gölde bugüne kadar yapılmış araştırmalarda toplam altı balık türü tespit edilmiştir. Bunlar, Cyprinidae familyasından; Capoeta baliki, Cyprinus carpio, Carassius gibelio, Squalius cephalus ve Tinca tinca, kıyı bölgelerde Poecilidae familyasından Gambusia holbrooki’dir. Gölde ayrıca ekonomik öneme sahip kerevit (Astacus leptodactylus) yaşamaktadır. 2000’li yıllardan itibaren giderek artış gösteren antropojenik faktörlere daha çok maruz kalan Yeniçağa Gölü için etkin bir yönetim stratejisi uygulanamayışı sonucunda göldeki ticari türlerde ciddi azalışlar gözlenmiştir. Aynı süreçte sonradan göle aşılanan egzotik türler ile göl ekosisteminde değişikler meydana gelmiştir. Bu çalışma ile son 15-20 yılda gölde meydana gelen değişimler tespit edilerek, gölde başta ticari balık avcılığı olmak üzere uzun vadeli rasyonel bir göl yönetimi için önerilerde bulunulmuştur. Elde edilen bulgulara göre Yeniçağa Gölü’nde kooperatife ortak balıkçılar tarafından üç balık türü (sazan, kefal, kadife) avlanarak pazara sunulmaktadır. Av verilerinde yıllar içerisinde çok fazla bir dalgalanma gözlenmemesine karşın, 2015 yılından itibaren karaya çıkarılan av miktarları radikal bir azalma eğilimine girmiştir. Göldeki populasyonların sürdürülebilirliği açısından; gölde baskın olarak bulunan S. cephalus üzerindeki av baskısının arttırılması, buna karşın C. carpio ve T. tinca üzerindeki av baskısının ise azaltılması çok önemlidir. Göldeki tüm balık türlerine kontrollü ve dengeli bir balıkçılık yapılması, tür çeşitliliğinin korunmasında etkili olacaktır.

This study was carried out to determine the growth and reproductive characteristics of Garra rufa Heckel, 1843 infested with Paradiplozoon bingolensis Civanova et al., 2013 in Göynük Stream, Bingol. A total of 267 G. rufa specimens were caught by a casting net between March 2015 and February 2016. The total length of G. rufa ranged from 8.5-19.1 cm and the total weights ranged from 5.8-58.7 g. The most intensive catching was in G. rufa population of 12.0-12.9 cm (30.0%) cm and 15.0-19.9 (25.2%) g in the groups. The mean condition factor was determined as 1.126±0.151 (0.607-1.646). The length-weight relationships were calculated as W= 0.0205 × TL2.758 (r2 = 0.891). The M: F ratio was 1:1.15. The sexual maturity length was recorded as 13 cm total length for males and 14 cm total length for females. Additionally, Paradiplozoon bingolensis was detected on only 218 G. rufa in this population. Of these positive samples, 173 P. bingolensis were isolated from male fish samples, while the females had 228 P. bingolensis. Therefore, female G. rufa specimens from this population were determined to be more predisposed to the infestation (p˂0.01).

The article describes the features of digital transformation for public administration and civil service. Public administration should become the basis of changed public relations; ensure the solution of the most significant issues affecting citizens through the use of data in a single information (digital) space. Coordinated work and ensuring horizontal and vertical cooperation between public authorities and local self-governments are an integral part of this process. Digital transformation is understood as the process of creating a single national digital space. The provision of public services and the execution of powers take place through the interaction of digital twins of government bodies and government civil servants. At the same time, other business entities, non-profit organizations, residents of the country, and their associations will be able to connect to this information space. The implementation of this concept will contribute to improving the efficiency and quality of public administration.

Developing the talents of the organization’s employees is becoming an increasingly important component for the formation of the organization’s competitive advantages since it is aimed at attracting and retaining high-quality specialists. The concept of talent can be described as a multifaceted phenomenon, including person’s abilities acquired from birth, skills obtained throughout life, and involvement in a favorite type of occupation. The article describes the main ways to identify employees’ talents, such as: “Tricky questions”, “Matrix for determining talent”, and analysis of employee’s personal life. The author recommends paying special attention to the context and examples of difficult situations from the employee’s work activities, the made-up decisions in these conditions, as well as to analyze the most successfully mastered areas. The author also identifies key positions regarding the motivation of talent development and emphasizes that the main driving force in creative activity is not monetary remuneration or evaluation of human efforts but opportunities for employees to show an aptitude to research, learn and develop. As a result of analyzing the experience of talent management in the public service of the city of Singapore, the article highlights such methods of working with talented employees as allocating working time for training, staff rotation, participation in inter- structural project teams, and mentoring. Also, the author considers the trend of introduction and use of artificial intelligence in the organization’s activities and its impact on the work of talented employees. It allows automating routine work and creating conditions for shifting the focus of employees to work creatively.

The level of transport infrastructure development directly affects the rate of economic growth. In 2018, in Russia, 67.1 % of the total volume of transported goods were delivered by road transport. However, we cannot talk about the full realization of the road transportation system since 57.6 % of public roads do not meet regulatory requirements. The available statistics indicate that, first of all, attention should be paid to the condition of the roads. The article analyzes the system for road maintenance in the constituent entities of the Russian Federation, considers the main regulatory documents governing the activities of road work suppliers and executive authorities in the field of road maintenance. The article examines and analyzes the advanced foreign experience in the field of technologies for servicing roads in the winter. As the result of analysis, the authors propose introducing performance-based contracts into the field of the road sector. The creation of an economically feasible form of performance-based contracts can lead to a decrease in the cost of road maintenance by 10-40 %.
