The substitution of live labor by machines and the need to perform more complex technical and technological operations creates qualitatively different requirements for labor resources. The emphasis is shifting towards the growth of qualifications and professional skills of the workforce, which necessitates the assessment and provision of conditions for the full formation and reproduction of their labor capital. The reproduction of labor capital occurs at the expense of targeted investments, which have a cyclical-wave character, starting from the initiation stage and ending with the process of evaluating the result obtained. Such an approach to assessing the cycle of reproduction of labor capital requires the development of a system of indicators for its evaluation at each stage of its formation. The article substantiates the application of the concept of a cyclic-wave approach to the study and analysis of labor capital and offers a methodological approach that allows you to cover each stage of the life cycle of labor capital reproduction, to evaluate it, both at the stage of investment and at the stage of their payback. The novelty of the presented article consists in the systematization of groups of indicators of labor capital, which allow to identify and evaluate the stages of its reproductive life cycle Practical approbation of the author's approach to assessing and identifying the life cycle of labor capital is based on the example of evaluating the effectiveness of the use of labor resources in Russia. As a general result of the study, the advantages of the proposed methodological approach are identified, priority directions of socio-economic policy in the field of labor capital are identified.

The relevance of the topic under study lies in the fact that, under the conditions of sanctions restrictions, the domestic economy needs its own strategy for the sustainable development of environmental management, which assumes not the transfer of dependence of income from use from foreign trade operations (as EU countries do), but the reduction of environmental costs for stable tax and non-tax payments from the use of natural resources. The purpose of the article is related to the study of prospects for improving the taxation of hydrocarbon raw materials on the principles of rational nature management for the sustainable development of the Russian economy in the conditions of sanctions restrictions. Based on the use of regression and variance analysis methods and the study of international experience, the potential opportunities for improving environmental taxation in the direction of rational nature management and support for «green» economic growth are substantiated. The analysis of effective taxation in Russia on the subject of hydrocarbon dependence of the budget of the Russian Federation is carried out, the assessment of taxation of the rational level of environmental management in Russia is given. The contradiction of environmental taxation in the conditions of sanctions restrictions from the standpoint of federal budget profitability and sustainable economic development is revealed. To resolve this contradiction, tax optimization measures based on the principles of rational nature management are proposed. Since the export of hydrocarbon raw materials is the main source of revenue generation of the state budget of the Russian Federation, the authors substantiate the advantages of environmental taxation in the conditions of modern sanctions restrictions.

Authors: Davidge Gail , Brown Lindsey , Lyons Moira , Blease Charlotte , French David , van Staa Tjeerd , McMillan Brian
Published: February 2023

Background

NHS England have announced plans to enable all adult patients to have full prospective access to their primary care record by default. Despite this, little is known about the views and experiences of primary care staff regarding patients’ online records access (ORA).

Aim

To examine the views and experiences of primary care staff regarding patients having online access to their primary care health record, and how this service could be supported and improved.

Design and setting

A qualitative study of a purposive sample of 30 primary care staff in England.

Method

Online semi-structured interviews with primary care staff were conducted between December 2021 and March 2022. Verbatim transcripts were analysed inductively using thematic analysis.

Results

Most staff agreed with the principle of patient access to online health records but had mixed feelings regarding the potential benefits and drawbacks of applying this in practice. Staff identified opportunities for improving patient engagement, health literacy, and efficiencies in some administrative workloads, as well as concerns about maintaining the clinical integrity of patient records and ensuring that staff and patient safety and wellbeing are protected.

Conclusion

Participants acknowledged that ORA may transform the purpose and function of the record and that ORA has potential to instigate a significant cultural shift in primary care, changing how staff work and relate to patients. This underlines the need for additional staff training and support to expand capability and capacity to adapt practice and enhance patient engagement with, and understanding of, their health records.

Published: February 2023

Key Points

Health professionals resisted practice change in environments of low infection where the perception of a need to change is small.

Standardizing care of central venous catheters for hemodialysis requires breaking down silos of practice to benefit all patients.

Knowledge of and adherence to guidelines, formal change management, and ongoing facilitation are required to implement standardized care.

Background

Implementation of a care bundle standardizing insertion, management, and removal practices to reduce infection related to central venous catheters (CVCs) used for hemodialysis was evaluated in a stepped wedge, cluster randomized controlled trial conducted at 37 Australian hospitals providing kidney services, with no reduction in catheter-related blood stream infection detected. This process evaluation explored the barriers, enablers, and unintended consequences of the implementation to explain the trial outcomes.

Methods

Qualitative process evaluation using pre-post semistructured interviews with 38 (19 nursing and 19 medical) and 44 (25 nursing and 19 medical) Australian health professionals involved in hemodialysis CVC management. Analysis was guided by the process implementation domain of the Consolidated Framework for Implementation Research.

Results

Key influences on bundle uptake were that clinicians were open to change that was evidence-based and driven by guidelines and had a desire to improve practice and patient outcomes. However, resistance to change in environments of low infection, working in silos of practice, and a need for individualized delivery of patient education created barriers to uptake. Unintended effects of increased costs and lack of interoperability of systems for data collection were reported. Because the trial was in progress at the time of qualitative data collection, perceptions of the bundle may have been influenced by the fact that practices of participants were being observed as a part of the trial.

Conclusion

This national process evaluation revealed that health professionals who reported experiencing a benefit viewed the bundle positively. Those who already provided most of the recommended care or perceived that their patient population was not included in the research evidence that underpinned the interventions, resisted the implementation of the bundle. Potentially, formal change management processes using facilitation may improve implementation of evidence-based practice.

Published: February 2023

Generation of the huge amount of bio-waste and their residues, including incineration ash, is a major technical and sustainability problem. To solve this problem, incorporating nutrient-rich residues into crop production has become an efficient practice to increase crop production. Vermicomposting of these wastes could be a viable option to manage both biowastes and their products in an environmentally friendly manner and close the material loop in bioenergy production. Therefore, the main objective of this study was to investigate the effect of vermicompost from biomass ash under hot and dry climatic conditions in summer on growth, yield and yield components of sweet sorghum (Sorghum bicolor var. saccharatum (L.) Mohlenbr). The high photosynthetic activity of sweet sorghum is important for biofuel production under conditions of high solar energy and water scarcity. This study provides a general overview of the feasibility of biomass ash vermicomposting processes and their potential use as a nutrient source for C4 sorghum under Bitlis ecological conditions of high solar potential and low water availability. Under Bitlis climatic conditions, the best yield was obtained when vermicompost was applied with a biomass ash content of 10.0% (T3).

Authors: Rodríguez-Vega Aidee , Quintal-López Rocío , Salinas-Boldo Claudia
Published: February 2023

Human rights activists are subjects who, faced with a situation of injustice, in which power relations are unbalanced, exercise resistance against this oppressive power. In this article we analyzed how these actions that the subject undertakes in situations of oppression are configured. From a qualitative approach, a phenomenological design was used. Through in-depth interviews with eight human rights activists, it was found that the subjects are learning various strategies of struggle and resistance. Along the way, they have discovered that proactive strategies often work better than confrontational ones. They have moved away from victimization as a cover letter and have discovered the importance of continuing to learn new strategies. Based on the information obtained, it can be concluded that in the exercise of activism, force vectors are mobilized that reproduce social orders or that reject them. The form of resistance of a subject acquires meaning when understanding a society not only in its institutional dimensions, but also as a display of human relations.

Experimental evaluation of effects of absorption layer on parametric ultrasound
Authors: Nomura Hideyuki , Imaizumi Takuma
Published: February 2023

This study investigated the effects of absorption attenuation on parametric ultrasound (US) for application to low-frequency (LF) US measurement and imaging. The effects of an absorption layer on the sound field and pulsed wave of parametric US at several hundred kilohertz in water were experimentally evaluated via a comparison with LF US directly radiated from a transmitter. The results indicate that the variations of the shape and amplitude of the parametric US field and waveform due to the insertion of an absorber were more significant than those for LF US at the same frequency. However, these effects can be mitigated when an absorber is inserted at a far distance from a transmitter. These results suggest that for the application of parametric US in measurement and imaging, a low-absorption medium must be inserted between a transmitter and absorbing material to be evaluated in order to grow secondary waves sufficiently.

Published: February 2023

Ultrasonic welding of plastics has been used in a wide range of industries and improving welding quality and production speed are still important issues. This paper introduces a method to evaluate the welding condition during welding. In this method, vibrations propagated during welding were acquired using a piezoelectric element. By fast fourier transform analysis, tracking analysis, and calculation of the data, the total harmonic distortion with the welding time was obtained. The welding condition can be determined by comparing the welding strength against the welding time obtained from the 180° peeling test. As a result, it was found that the propagated vibration has characteristics that indicate the completion of welding, making it possible to efficiently evaluate the quality of the weld.
Universal quantum computer based on carbon nanotube rotators
Authors: Ezawa Motohiko , Yasunaga Shun , Iizuka Tetsuya , Higo Akio , Mita Yoshio
Published: February 2023

We propose a universal quantum computer based on a chain of carbon nanotube rotators where one metallic plate is attached to each rotator. The dynamical variable is the rotational angle ϕ. The attached plate connected to ground electrostatically interacts with two fixed plates. Two angle positions ϕ = 0, π are made stable by applying a voltage difference between the attached plate and the two fixed plates. We assign ϕ = 0 and π to the qubit states ∣0〉 and ∣1〉. Then, considering a chain of rotators, we construct the arbitrary phase-shift gate, the NOT gate and the Ising gate, which constitute a set of universal quantum gates. They are executed by controlling the voltage between various plates.
Mixed-mode RF reflectometry of quantum dots for reduction of crosstalk effects
Authors: Machida Masato , Mizokuchi Raisei , Yoneda Jun , Tomura Takashi , Kodera Tetsuo
Published: February 2023

RF reflectometry is a promising technique for spin qubit readout, suitable for large-scale integrated qubit systems by combination with multiplexing techniques and gate-based readout. However, one of the challenges in such systems would be that the accuracy of RF readout of individual qubits can be degraded by crosstalk among dense RF readout lines. In this study, we propose a mixed-mode RF reflectometry to reduce the effect of the crosstalk and verify its effectiveness by electromagnetic field simulations. The results of the simulations show the possibility of suppressing the influence of crosstalk by using mixed modes.

حق الأنا في القتل الرحيم مقتطف من رسالة دكتوراه حول حق الأنا وأصوله وآثاره في الفقه الإسلامي
Authors: مير علي يحيى , حاجي احمد
Published: February 2023

إحدى آثار الحق على الذات هي القتل الرحيم (Euthanasia). قد يتم إجراء القتل الرحيم من قبل الفرد أو من قبل شخص آخر، وفي كل حالة، قد يتم ذلك بالفعل أو من خلال ترك الفعل. في حال تم من قبل المريض، يعتبر هذا الفعل حرامًا، وتعتبر الأدلة الشرعية هذا الفعل بمثابة الانتحار.
من حيث الحكم الظرفي، بما أن المريض قد ساعد في القتل، يتم نفي الضمان، ولكن عندما يُرتكب القتل بدافع الشفقة من قبل شخص آخر، لا يُعتبر انتحارًا حتى لو كان الشخص راضيًا عن ذلك.
من حيث الحكم الظرفي، هناك اتجاهان بين الفقهاء. ومع ذلك، يقبل المادة 365 من القانون المدني الإيراني نظرية نفي الضمان. في الحالات التي يتم فيها القتل الرحيم عبر الفعل أو ترك الفعل، على الرغم من أن الشخص قد ارتكب فعلًا محرمًا، إلا أنه لا يُواجه بنفي العلاقة الضمانية من حيث نفي العلاقة.

لقد كانت الحياة البشرية دائمًا مرتبطة بمفهوم الحب؛ حيث تكرر هذا المفهوم في أعمال الشعراء والكتّاب، مما خلق جذبًا هائلًا. إن تجسيد الحب تأثر بالأحداث الثقافية والأدبية والاجتماعية للبشر عبر العصور والأماكن المختلفة. يُعدّ ناجي وجاف من أبرز شعراء العرب والأكراد في كتابة السوناتات في العصر المعاصر. وللأسف، يُعد جاف أقل شهرة عالميًا نظرًا لقلة الأبحاث من قبل المؤلفين والعلماء في هذا المجال؛ إلا أنه يُعتبر واحدًا من أبرز الشعراء الأكراد. كان كل من ناجي وجاف مصممين على كتابة السوناتات؛ ولذلك، يُعتبر من المناسب أن نعتبرهم روادًا في هذا الشكل الشعري، وخاصة السوناتات الرومانسية.
يرى ناجي محبوبته بشكل مختلف، حيث يمتلك حبًا نقيًا وبراءً؛ ويعبّر عن حياة مليئة بالحب والعبادة جنبًا إلى جنب مع الحزن والأسى. كما يوضح إحسان عباس قائلاً: "كل تعبيرات الطبيعة والأشياء تنعكس في حزن الشاعر وأساه، فلا الخمر ستريح هذا الحزن حتى وإن حصل على محبوبته". بينما يعكس جاف الجوانب المادية والجسدية للحب ومحبوبته. إن الموقف المادي والشكلاني لجاف متجذر في حبه الكبير للمحبوبة.
غالبًا ما يتأثر الشعراء الأكراد بشعراء وكتّاب الأمم الأخرى. يختلف الرابط بين الحب المادي والحب النقي في وجهة نظر هذين الشاعرين. يعتقد ناجي أن الحب المادي أو الشكلي هو بداية الحب الإلهي النقي، بشرط أن لا يرتبط هذا الحب بالشهوة؛ لكن هذا الرأي لا يظهر بوضوح في أعمال طاهر بك جاف، ربما بسبب حالته المعيشية التي كانت أرستقراطية إلى حد ما وخالية من الهموم. ربما يمكن ملاحظة تأثير هذا العامل في حب جاف المادي والشكلاني.

Published: February 2023

Ang panitikang pambata ay hindi lamang pambata, dahil bukod sa kakayahan nitong magbigay ng kaalaman at tulungan ang bata na maintindihan at matutuhang magamit ang wika, taglay din nito ang kakayahang mailipat o maipasa ang kultura ng isang lipunan sa mga batang binabasahan o nagbabasa. Tatlo ang kuwentong Pambata na sinuri at gamit ang Ekokritisismo sa pagsusuri.
Lumabas sa pagsusuri ang direktang paglalahad at paglalarawan sa panimula ng mga kuwento na nagbubukas sa kamalayan ng mga bata. Sa saglit na kasiglahan ay nagpakita ng mga salitang nagpagalaw sa imahinasyon, diyalogo at pagsasalaysay, simbolismo at mga tayutay, at matatalinghagang salita. Sa Katawan, ipinakita ang kinaharap na parusa ng mga tauhan na nagbigay daan upang magkaroon ng kulay ang mga pangyayari na nagdulot ng pagiging matatag at positibo sa buhay ng mga tauhan, at sa Wakas, ipinakita ang malungkot na kinahinatnan sapagkat naubos ang lahat ng kanilang ari-arian, natuto at nagbago ang pag-uugali.
SUSING SALITA: Ekokritisismo, Kuwentong Pambata, Kuwentong Pangkalikasan, climate change

Estudios in vitro e in vivo han demostrado una relación positiva entre las características fisicoquímicas y la composición fitoquímica de la miel con el efecto benéfico en el tratamiento de afecciones leves como cicatrización de heridas, hasta procesos complejos de inflamación, estrés oxidativo, o infecciones microbianas. Así, la miel de abejas sin aguijón representa un producto con potencial terapéutico.
Does Role Commitment and Occupational Stress is Corelated? A Study from the Perspective of Secondary School Teachers
Authors: - Tulika Bansal
Published: February 2023

The present research was undertaken as part of completion of master’s degree in psychology and is based on a assumption that like any other occupation, teaching and teacher’s role are also impacted with occupational stress. The study aims at finding out the correlation between role commitment and occupational stress particularly among secondary school teachers of Delhi NCR. The research employs quantitative descriptive research design and uses standardised tools namely Occupational Stress Index (OSI) by Srivastava and Singh and Teacher’s Role Commitment Scale (TRCS) by Dr. Meena Buddhisagar Rathod and Madhulika Varma. The sample of 120 secondary school teachers was collected using random sampling technique. karl pearson test of correlation was applied for finding the correlation between role commitment and occupational stress among teachers. The results shows that there is no significant correlation between role commitment and occupational stress among secondary school teachers; the teacher’s commitment towards their role don’t get affected by occupational stress they corroborate.

E-commerce refers to the buying and selling of services over the internet as well as the data and money transfers required to complete the sales. It is often referred to as online commerce or electronic commerce. India's e-commerce market is growing quickly.
E-commerce is unquestionably a business alternative that must be investigated in the future. E-commerce forecasts indicate a substantial increase in the number of businesses in our nation. Indian e-commerce has shown tremendous growth in recent years, supported by a growing internet user base on mobile phone devices. Due to widespread internet use and advanced electronic devices, India's e-commerce sector is expanding at a rapid rate. Since the majority of people are unaware of online fraud and corruption when conducting transactions, darkness rules.
This is by far the greatest difficulty that the Indian e-commerce sector is currently facing. Even financial transactions can be completed quickly and effectively with e-commerce from anywhere in the world. Future generations will feel more at ease making purchases exclusively online.
The study's goal is to highlight the idea of e-commerce. The secondary data employed in this study's research approach were listed in various online databases of books, academic papers, and related e-commerce articles.

For the proper sustainable management and utilization of this water resource, it is mandatory to take up the steps to monitor the lake regularly for sustainable fisheries.
Enumeration of Generalized Dyck Paths Based on the Height of Down-Steps Modulo $k$
Authors: Heuberger Clemens , Selkirk Sarah J. , Wagner Stephan
Published: February 2023

For fixed non-negative integers $k$, $t$, and $n$, with $t < k$, a $k_t$-Dyck path of length $(k+1)n$ is a lattice path that starts at $(0, 0)$, ends at $((k+1)n, 0)$, stays weakly above the line $y = -t$, and consists of steps from the step-set $\{(1, 1), (1, -k)\}$. We enumerate the family of $k_t$-Dyck paths by considering the number of down-steps at a height of $i$ modulo $k$. Given a tuple $(a_1, a_2, \ldots, a_k)$ we find an exact enumeration formula for the number of $k_t$-Dyck paths of length $(k+1)n$ with $a_i$ down-steps at a height of $i$ modulo $k$, $1 \leq i \leq k$. The proofs given are done via bijective means or with generating functions.
A New Construction of Strongly Regular Graphs with Parameters of the Complement Symplectic Graph
Authors: V. Kabanov Vladislav
Published: February 2023

The symplectic graph $Sp(2d, q)$ is the collinearity graph of the symplectic space of dimension $2d$ over the finite field of order $q$. A $k$-regular graph on $v$ vertices is a divisible design graph with parameters $(v,k,\lambda_1,\lambda_2,m,n)$ if its vertex set can be partitioned into $m$ classes of size $n$, such that any two different vertices from the same class have $\lambda_1$ common neighbours, and any two vertices from different classes have $\lambda_2$ common neighbours whenever it is not complete or edgeless. In this paper we propose a new construction of strongly regular graphs with the parameters of the complement of the symplectic graph using divisible design graphs.
