The article discusses the process of the digitalization of the educational organization of secondary vocational education. When automating routine processes, at some point, problems may arise in the transition from solving local accounting problems to submitting regulated reports. Often, digitalization becomes the only possible solution to the problems of combining the performance of job tasks based on data from various departments. This is especially evident when implementing integration with external federal information systems. The development of digital services for students with the help of the information service “NaLentu!” (”Go to a Class!”) is shown. Based on it, the mailing of the schedule, the “digital student’s record-book”, and the order of documents are implemented. It is described how one of the federal systems became the reason for the digitalization of processes in social accounting, the appointment and accrual of grants. The problems of the implementation of the accounting system on the part of employees, in particular, the perception by some of them of digitalization as a threat to their interests, are indicated. Further automation trends after the implementation of information systems in the decision of the central tasks of the educational organization are demonstrated. The stages of the introduction of information systems for accounting for vocational training and additional professional education are described, the analysis of the results of their implementation on the basis of College of Oil and Gas in Achinsk is given.

Structural Regulation

Between 2000 and 2010, new institutional arrangements were created for UK broadcasting regulation, built upon a radical rethinking of communications policy. This article examines key changes arising from Labour's media policy, the Communications Act 2003 and the work of Ofcom. It argues that changes within broadcasting were less radical than the accompanying rhetoric, and that contradictory tendencies set limits to dominant trends of marketisation and liberalisation. The article explores these tendencies by reviewing the key broadcasting policy issues of the decade including policies on the BBC, commercial public service and commercial broadcasting, spectrum and digital switchover, and new digital services. It assesses changes in the structural regulation of media ownership, the shift towards behavioural competition regulation, and the regulation of media content and commercial communications. In doing so, it explores policy rationales and arguments, and examines tensions and contradictions in the promotion of marketisation, the discourses of market failure, political interventions, and the professionalisation of policy-making.

External Stimuli

Abstract The real estate market is an open system, which implies that it is able to exchange signals with other open systems and dynamic systems. The evolution of a market system over time can be described mathematically. If the system's sensitivity threshold to external stimuli is exceeded, it becomes destabilized and moves from a near-balanced state to a state that is far from equilibrium. Those dynamic processes often induce key changes in the system's trajectory of evolution. In search of equilibrium, the system becomes transformed in a process of discontinuous and discrete changes in state variables. The above statement constitutes the research hypothesis in this article. In this study, an attempt was made to develop a mathematical model for visualizing the evolutionary path of the real estate market in the form of continuous changes interrupted by discontinuous changes. The qualitative transformation of the system will be evaluated with the use of the catastrophe theory.

<b>Abstract:</b> The production of olefins via on-purpose dehydrogenation of alkanes allows for a more efficient, selective and lower cost alternative to processes such as steam cracking. Silica-supported pincer-iridium complexes of the form [(≡SiO-<sup>R4</sup>POCOP)Ir(CO)] (<sup>R4</sup>POCOP = κ<sup>3</sup>-C<sub>6</sub>H<sub>3</sub>-2,6-(OPR<sub>2</sub>)<sub>2</sub>) are effective for acceptorless alkane dehydrogenation, and have been shown stable up to 300 °C. However, while solution-phase analogues of such species have demonstrated high regioselectivity for terminal olefin production under transfer dehydrogenation conditions at or below 240 °C, in open systems at 300 °C, regioselectivity under acceptorless dehydrogenation conditions is consistently low. In this work, complexes <a>[(≡SiO-<i><sup>t</sup></i><sup>Bu4</sup>POCOP)Ir(CO)] </a>(<b>1</b>) and [(≡SiO-<i><sup>i</sup></i><sup>Pr4</sup>PCP)Ir(CO)] (<b>2</b>) were synthesized via immobilization of molecular precursors. These complexes were used for gas-phase butane transfer dehydrogenation using increasingly sterically demanding olefins, resulting in observed selectivities of up to 77%. The results indicate that the active site is conserved upon immobilization.

Expectations about pain and analgesic treatment depend on medical providers’ facial appearances

Trait Impressions

There is a robust link between patients’ expectations and clinical outcomes, as evidenced by the placebo effect. These expectations are shaped by the context surrounding treatment, including the patient-provider interaction. Prior work indicates that the provider’s behavior and characteristics, including warmth and competence, can shape patient outcomes. Yet humans rapidly form trait impressions of others prior to any in-person interaction. Here, we tested whether trait-impressions of hypothetical medical providers, based purely on facial images, influence participants’ choice of medical providers and expectations about their health following hypothetical medical procedures performed by those providers in a series of vignettes. Across five studies, participants selected providers who appeared more competent, based on facial visual information alone. Further, providers’ apparent competence predicted participants’ expectations about post-procedural pain and medication use. Participants’ perception of their similarity to providers also shaped expectations about pain and treatment outcomes. Our results suggest that humans develop expectations about their health outcomes prior to even setting foot in the clinic, based exclusively on first impressions. These findings have strong implications for health care, as individuals increasingly rely on digital services to choose healthcare providers, schedule appointments, and even receive treatment and care, a trend which is exacerbated as the world embraces telemedicine.
