Abstract:

In France, the railway lines are divided into the national and international lines. While the former has a proper implementation of the railway signalling systems as relay-based or computer-based systems, the latter follows the guidelines defined by the ERTMS standards, focusing on the interoperability throughout Europe. In a previous work we presented how the national legacy relay-based Railway Interlocking Systems (RIS) can evolve to use a computer-based technology in order to benefit from its advantages. In this present article, we present how these computer-based systems can be used in order to allow the evolution from a national line towards an ERTMS compliant international line. This proposition is based on the fact that the previous work provides the support for evolving the track-side technologies with, for instance, the use of GNSS for the train geo-localisation instead of electrical circuits-based train detection systems. Then, a discussion of the impact of this evolution over the system safety is presented.

Abstract:

AbstractWhile recent research continues to emphasize the importance of digital entrepreneurship, the historical terminology of this field is often overlooked. Digital entrepreneurship tends to be considered a new phenomenon despite emerging in the early 1990s. Building on a scoping literature review, this study analyzes 1354 publications that use nine different terms interchangeably to describe the phenomenon of digital entrepreneurship. Based on the number of publications per year, three eras in the historical development of digital entrepreneurship research are outlined. Digital technologies are identified as external enablers, and certain practical events are considered to be influencing factors. The results show that recent research has not adequately recognized the contributions of previous publications and that the understanding of digital entrepreneurship is quite similar with regard to the terms used and over time. This study shows how emerging digital technologies, such as artificial intelligence, blockchain technology, and big data analytics, might shape the future of digital entrepreneurship research. The study occupies the intersection between entrepreneurship and information systems literature and its main contribution is to provide new insights into the eras of digital entrepreneurship from the past to the present and into the future.

Abstract:

Enhanced Recovery After Surgery (ERAS®) was implemented across Alberta Health Services, a single payer publicly funded provincial health system starting in 2013. Implementation across multiple provincial sites in colorectal surgery reduced postoperative complications by 12% and median length of stay by one day. Subsequent implementation in gynecologic oncology reduced postoperative complications by 17% and length of stay by 2 days in high complexity surgery. Implementation has had an estimated net savings in the province of $7.22 million Canadian dollars (CAD) over 5 years with a return on investment of $1.05 to $7.31 for every dollar invested in the project. Patient involvement enabled success of the program, with support, education, and mitigation of patient stress identified as key components for success. Provider knowledge and motivation were essential to ensure ongoing compliance with ERAS guidelines. Provider education, and demonstration of improvement in patient outcomes using audit is one method to ensure continued motivation from care providers. Systemlevel leadership is essential to provide consistent messaging and support for initiatives, while providerlevel leadership in the form of physician champions and nurse coordinators ensures compliance and appropriate integration of ERAS into daily practice. Implementation of ERAS across a unified health care system has improved patient outcomes while saving resources. Further research into expansion of the program to community hospitals and all surgical domains is underway.

Abstract:

Enhanced Recovery After Surgery (ERAS) is a model of care that involves the implementation of care pathways before, during and after surgery designed to improve patient’s experience throughout the perioperative period. Yet, the implementation of individual ERAS protocol elements is not sufficient. This approach requires the creation of a multidisciplinary work team, systematic recording of data and mthe use of the information recorded to implement a cycle of continuous improvement. Since 2015, 1331 patients have been recorded by Hospital Italiano de Buenos Aires. Median length of hospital stay was 4 days and median readmission rate was 7.3%. The overall adherence to the protocol elements was 56% (88% in the preoperative period, 60% in the intraoperative period and 39% in the postoperative period) There was a linear and inverse correlation between the adherence to the program and length of hospitalization for the most common surgical procedures, with an average decrease of one day of hospitalization for each 10% increase in adherence with the program for the most common surgical procedures. Despite these results, we have encountered difficulties in the data recording systems limiting the implementation of the cycle of continuous improvement. The creation of a multidisciplinary team, with fluent and efficient communication, is essential for the implementation of an ERAS® program capable of reducing length of hospital stay, morbidity and readmission rates.

Abstract:

Purpose – The paper aims to demonstrate a method for creating an electronic resource management system (ERMS) from freely available open source tools. This system will help manage bibliographic data, holdings and statistical and financial data for electronic databases and periodicals. Design/methodology/approach – The paper demonstrates how to create a database and interface for managing serials and electronic resources using PHP and MySQL within a *AMP framework. Findings – By following this approach, libraries can maintain structured data regarding their electronic and print holdings with minimal expense and with flexibility that is not necessarily possible through large commercial products, while avoiding the burden of implementing a large, open source solution. Originality/value – While many products exist on the market, either commercial or large open source solutions, there is little documentation on how to create a small scalable ERMS. This paper attempts to demonstrate a method.

Abstract:

AbstractConcerns with the social inadequacy of architecture and the movement towards user-centred design call for new perspectives and architectural visions that can help alleviate usability problems and make buildings more user-friendly and accommodating in supporting user operations. Accordingly, this study proposes the concept of the sociospatial system. This conceptualization is based on premises of the systems approach and a social science interpretation of the problem. We provide a foundation for relating spatial-material objects and sociocultural phenomena, for homogenizing different discipline perspectives, and for developing relational descriptions of the systems components. This allows the built environment to be represented in terms of the sociocultural organism that it accommodates. The elastic concept of the sociospatial system described herein can be used as a holistic framework for the study of sociospatial interactions; including facilities programming and design, where this way of thinking can facilitate a holistic interpretation of a wide array of considerations.

Abstract:

Purpose Technology has influenced the implementation of electronic records management systems (ERMS) in government agencies. The high incidence of poor service delivery in government agencies is a key factor that has put pressure on the government to implement ERMS. Despite the potential benefits of implementing ERMS, the adoption and use of these programs has been slow and some systems have failed. Therefore, the purpose of this study is to assess how Tlokweng land board (TLB) implemented its electronic records management program using Kotter’s model and awareness, desire, knowledge, ability and reinforcement change model. Design/methodology/approach The study adopted a pragmatic paradigm and used a case study research design to collect data at TLB. The research made use of mixed methods approach to collect data using questionnaires, interviews and document reviews. Purposeful sampling was used to solicit data from 53 participants in the land board. Findings The findings of the study revealed that communication has been used as the most effective tool for managing change at TLB. However, TLB has not yet managed to reinforce the change implemented because of the lack of adequate training and motivation of change champions. Moreover, the change management team has little training on the change management framework produced by the Ministry of Lands and Housing. Research limitations/implications The study was limited to one land board in Botswana. Therefore, the findings may not be generalized to all land boards. Originality/value This is the first study to be conducted in Botswana that has assessed change management practices in the implementation of records management systems. This study therefore recommends adoption of the change management lens/framework by a records professional when implementing ERMS.

Abstract:

This article discusses the relationship between educational institutes that use ERMS and the performance of those institutions. This article uses a mixed explanatory method that incorporated quantitative and qualitative approaches. The quantitative method collected the responses from 364 participants. This was followed by a qualitative approach where experts were interviewed to verify the model. The results generated using the quantitative approach demonstrated that the quality of the system, information, and service as well as the security provided by the system had a significant positive relationship with the successful adoption of ERMS, which in turn improved performance. Moreover, the qualitative results that gathered through the experts confirmed the findings and contributed to enriching the understanding of the adoption of ERMS in educational institutions.

Abstract:

Generally in both elemental and compound rare earth systems, the 4f levels are treated as core states with little interaction with the 5d hybrid conduction and valence band states. In the present study, the band dispersions of the rare-earth pnictide erbium arsenide ( ErAs ) are observed to be perturbed from this expectation. Both photoemission symmetry selection rules and ab initio calculations provide evidences of the 4f - 5d hybridization. This finding is also supported by the f–f resonant transition excitation energy shifts in characteristic electron-energy-loss spectroscopy (EELS).

Abstract:

Railway systems have evolved considerably in the last years with the adoption of new communication technologies. Aiming to achieve a single European railway network, the European Rail Traffic Management System (ERTMS) emerged in Europe to substitute multiple and noninteroperable national railway communication systems. This system and its security strategies were designed in late 1990s. Recent works have identified vulnerabilities related to integrity, authenticity, availability, and confidentiality. In the context of defining effective countermeasures to mitigate potential vulnerabilities, these vulnerabilities have to be analysed. In this article we introduce a framework that attempts to challenge ERTMS security by evaluating the exploitability of these vulnerabilities.

Abstract:

In the era of the dynamic development of rail transport caused by the implementation of many railway projects, some problems related to the implementation of railway investments are beginning to be noticed, which refer to obtaining a permit for placing in service of structural subsystems. Most of the investments are co-financed from EU funds, and their main goal is to increase speed on railway lines with the same or improved safety level. In addition to the modernization of railway lines with accompanying infrastructure, devices and power grids or railway traffic control devices, railway lines are equipped with trackside ERTMS / ETCS systems. All modernized railway lines are subject to a certification process following European and national law. Concerning lines equipped with ERTMS / ETCS systems, which have already been certified and accepted to operation, some actions are taken to improve the operational performance of the railway infrastructure. For this reason, it is necessary to assess the impact of investments on ERTMS / ETCS systems already installed, which have a valid EC verification certificate and have received or expect an authorization for placing in service issued by the Office of Rail Transport.

Canadian Journal of Chemistry 81, no. 4 (April 1, 2003): 319–29. http://dx.doi.org/10.1139/v03-063.

Full text

Abstract:

Alkoxyethanol + alkane systems have been examined in the framework of the ERAS model. An exact expression for the molar excess heat capacity at constant pressure, CPE, of solutions formed by a self-associated compound and an inert solvent has been derived. The CPE and the molar excess enthalpies (HE) and excess volumes (VE), as well as the molar enthalpies of vaporization of the pure alkoxyethanols, are represented accurately by ERAS. The calculated curves for HE and VE are skewed towards high mole fractions of the alkane. The experimental curves are more symmetrical. The opposite behaviour is observed for CPE in solutions with 2-ethoxyethanol, 2-propoxyethanol, or 2-butoxyethanol. The differences between the experimental and theoretical values arise because ERAS does not properly take into account the enhanced dipoledipole interactions due to the formation of intramolecular H-bonds in alkoxyethanols. As in previous applications, ERAS cannot simultaneously represent molar excess Gibbs energies and liquidliquid equilibria. DISQUAC, a purely physical theory, improves ERAS predictions for HE (except at high temperatures and pressures) and for CPE. Liquidliquid equilibria are also described more consistently. The self-association of alkoxyethanols via intramolecular H-bonds and the strong dipoledipole interactions lead to values of the self-association enthalpy and of the adjustable parameter of the physical contribution to HE and VE that are higher than those of the homomorphic 1-alkanols. In contrast, the equilibrium constants are lower. There is good agreement between the partial molar excess enthalpies at 298.15 K and infinite dilution of 2-alkoxyethanol in 2-alkoxyethanol(1) + n-heptane(2) mixtures and the values of the self-association enthalpies. Key words: alkoxyethanol, intermolecular, intramolecular, H-bond, dipoledipole interactions.

Abstract:

European Railway Traffic Management System/European Train Control System (ERTMS/ETCS) is a recent standard aimed at improving performance, safety and inter-operability of modern railways. In order to be compliant to ERTMS/ETCS, a railway signalling system must meet strict nonfunctional requirements on system level failure modes. In this paper, a multiformalism model is employed to perform an availability analysis of an ERTMS/ETCS reference architecture at early phases of its development cycle. At this aim, a bottom-up analysis is performed from subsystem failure models (expressed by means of Generalized Stochastic Petri Nets, Fault Trees and Repairable Fault Trees) up to the overall system model. The modular approach, here used, allows to evaluate the influence of basic design parameters on the probability of system-level failure modes and demonstrates that system availability is within the bound required by the ERTMS/ETCS specification. The results show that the multiformalism modeling approach helps to cope with complexity, eases the verification of availability requirements and can be successfully applied to the analysis of complex critical systems.

In this paper, the Prigogine?Flory?Patterson (PFP) theoretical model and the extended real association solution (ERAS) model for the prediction of the excess molar volumes of 17 binary sets of alcohols (methanol, ethanol, propan-1-ol, butan-1-ol, butan-2-ol and pentan-1-ol) with benzene, chlorobenzene, acetonitrile, hexan-1-amine and n-heptane were tested at 298.15 K and atmospheric pressure. The binary sets contained 333 experimental data points for 11 different compounds. The ERAS model demonstrated better correlative characteristics for binary mixtures comparing to PFP model. The ERAS model is successfully applied on all binary systems except ethanol + benzene and propan-1-ol + benzene. PFP model gave less satisfactory results for all systems except butan-1-ol + hexan-1-amine, for which obtained results were acceptable.

Abstract:

Abstract We demonstrate refinement-based formal development of the hybrid, ‘fixed virtual block’ approach to train movement control for the emerging European Rail Traffic Management System (ERTMS) level 3. Our approach uses iUML-B diagrams as a front end to the Event-B modelling language. We use abstraction to verify the principle of movement authority before gradually developing the details of the Virtual Block Detector component in subsequent refinements, thus verifying that it preserves the safety properties. We animate the refined models to demonstrate their validity using the scenarios from the Hybrid ERTMS Level 3 (HLIII) specification. We reflect on our team-based approach to finding useful modelling abstractions and demonstrate a systematic modelling method based on the state and class diagrams of iUML-B. The component and control flow architectures of the application, its environment and interacting systems emerge through the layered refinement process. The runtime semantics of the specification’s state-machine behaviour are modelled in the final refinements. We discuss how the model could be used to generate an implementation using code generation tools and techniques.

Abstract:

Binary mixtures of triethylamine (TEA) and alkanols have been investigated in the framework of DISQUAC. The systems are built by three contacts: aliphatichydroxyl, aliphaticnitrogen, and hydroxylnitrogen. The corresponding interaction parameters are reported and discussed. The former are avalilable in the literature but were modified (particularly the third dispersive (DIS) and quasichemical (QUAC) interchange coefficients) for sec- and tert-alkanols + n-alkanes using recent data on excess heat capacities at constant pressure (CEP) for systems of these alkanols with n-heptane. The interaction parameters for aliphatic-nitrogen contacts are purely dispersive. The structure dependence of the DIS and QUAC interchange coefficients of the hydroxyl-nitrogen contacts in 1-alkanols + TEA systems is similar to that found in other solutions previously investigated. The QUAC interchange coefficients remain constant from ethanol and are also valid for 2-alkanols and tert-butanol. Methanol behaves differently. A short discussion in terms of effective dipole moments is also included. DISQUAC represents well the thermodynamic properties examined: vapor-liquid equilibria (VLE), molar excess Gibbs energies (GE) and molar excess enthalpies (HE). DISQUAC provides better results than the Dortmund version of UNIFAC using the published geometrical and interaction parameters. ERAS parameters for 1-alkanols + TEA systems are also reported. Interactions between unlike molecules are stronger for solutions with methanol or ethanol. DISQUAC improves ERAS results on HE, while both models give similar results for GE. However, ERAS needs an specific parameter, with unknown temperature-dependence, to describe properly GE. The main advantage of ERAS is its ability to provide information on VE. Its main limitation is that can be only applied to those systems where association is expected. DISQUAC, a purely physical model, can be applied to any type of binary mixture, as it is followed from this and previous studies.Key words: theory, liquids, associated, thermodynamics, group contributions.

Abstract:

The huge potential offered by the implementation of a modern Train Control Information System (TCIS) could result in significant improvements in the railway sector in general. As a technology transfer, primarily in the European railway sector, the European Rail Traffic Management System (ERTMS) is expected to play an important role in providing better railway performances. However, the implementation of ERTMS entails certain dilemmas and disadvantages and the decision-making regarding it can be one of the crucial challenges for each railway. Having this in mind, the aim of this work is to propose a decision-making framework to support such a critical decision process through application of Strengths, Weaknesses, Opportunities, and Threats (SWOT) and Analytic Hierarchy Process (AHP) analyses. In the proposed approach, external and internal factors that simultaneously enhance and constrain ERTMS implementation were identified and presented through the SWOT analysis, while the AHP method was applied for the evaluation of the importance of identified factors. The thorough literature review represents a basis for creating a SWOT matrix and setting of judgments for the evaluation of the SWOT factors. The results of the AHP method highlight the importance of the factors within the SWOT matrix regarding ERTMS implementation. Results of the AHP method were checked by two additional weight assessments in order to provide the appropriate approach for factor evaluation. The proposed approach also shows a relatively simple and very suitable decision-making framework for consideration of other TCISs, too.

Abstract:

An electronic records management system (ERMS) is tightly linked with most of the daily activities of educational organisations and leads to enhance their performance and decision-making. The aim of this article is to identify the significant factors that could influence the ERMS adoption in higher professional education (HPE). The methodology of this article started with identifying the factors through theory analysis and literature and also recommended by experts. Technology–organisation–environment (TOE) theory was used for factor classification. Qualitative approach was used through the interview with experts to validate and verify the proposed framework. This article presents the results of a study which identifies the issues involved in the utilisation and adoption of ERMS. More than 100 previous works and six well-known theories were critically reviewed to identify the main factors for successful ERMS adoption in different areas with the aim of proposing a taxonomic framework that can depict and identify the main factors that have an impact on the success of ERMS adoption. The proposed framework includes 11 factors categorised into three dimensions. The framework is validated and verified by experts. The adoption factors identified here provide a sound theoretical basis for research to understand, support and facilitate the adoption of ERMS to HPE benefit. The proposed framework could help to improve educational outcomes and the successful implementation of ERMS.

Abstract:

As a key infrastructure for intelligent manufacturing, the Industrial Internet of Things (IIoT) can connect people, massive intelligent terminals, automated control equipment, and convergence nodes to achieve a high integration of industrial systems with advanced computing, sensor technology, fifth-generation technology (5G), and the Internet. How to realize the robust and reliable connection of massive IoT applications has become the research focus of industry and academia. However, the massive IoT industrial equipment, diverse business types, complex networking mode, and broadcast characteristics of wireless media have posed serious challenges to providing stable and reliable connections in industrial communication scenarios. In order to overcome this problem, the paper proposes an enhanced reliable access scheme (ERAS) for massive IoT applications in software-defined industrial heterogeneous networks. Based on the idea of software-defined networking (SDN), the ERAS is designed from two perspectives of the control plane and the data plane. Based on the idea of greedy algorithms, ERAS uses priority, interference set, deadline, and other information to find the local optimal solution and then obtain the global optimum. First, low-priority periodic data is accessed to the channel based on the earliest deadline. Then, high-priority data (such as control and interactive services) judges the channel occupancy status according to the access flow table, and if there is an idle channel in the current time slot, it is normally accessed. Otherwise, the subslots reserved with high priority in the control channel are used to preempt the low-priority channel. This preemption mechanism can ensure reliable and real-time connections for massive IIoT. Simulation results show that the ERAS performs better than traditional methods in terms of delay, deadline guarantee rate, and packet loss rate.

Abstract:

AbstractEngineering systems are complex, amongst others due to the interdependencies between actor and technical aspects. This complexity has consequences for the way of designing such systems and, in particular, for the decision-making process. Recognizing the impossibility of having an optimal system design in such complex systems, this article explores how a game theoretical characterization of a decision-making process assists in the organization and design of the process itself. In contrast to a game theoretical analysis, which results in optimal outcomes, the characterization is fed back to the designers of the decision-making process during the course of the process. The study analyses how the game concept characterization was used, i.e., which strategies were defined during the game theory interventions, and what the consequences of these strategies were for the design of the decision-making process. The design of a new safety system ERTMS for the Dutch railway sector is the context in which the study was performed. The contribution is a successful approach to complex decision-making in multi-actor systems by identification of multiple game concepts over time, with periodic feedback into the designing system, and not the actual decision-making itself. In short, it supported adapting to an actor focus on the process, it affected the role and responsibilities of the program management, it contributed to (de)coupling of issues, and it influenced the capability of creating awareness amongst actors of the urgency of the decision window. The paper ends with reflections on the experience of intervening in a decision-making process with game theoretical concepts.

Abstract:

Purpose Identification of factors for electronic records management system (ERMS) adoption is important as it allows organizations to focus their efforts on these factors to ensure success. The purpose of this paper is to identify the factors that influence ERMS adoption in the Yemeni oil and gas (O&G) sector. Design/methodology/approach This paper conducts a systematic literature review (SLR) to extract the most common factors that could facilitate successful ERMS adoption. Information technology (IT) experts were asked to rank the extracted factors via an e-mail questionnaire and to recommend specific critical success factors that must be given extra attention to increasing the success of ERMS adoption. Essentially, the proposed methodology is technology-organization-environment (TOE) modeling to examine the important factors influencing decision-makers in the Yemeni O&G sector regarding ERMS adoption. Findings This paper identifies factors influencing ERMS adoption based on SLR and an expert-ranking survey. The data that were collected from IT experts were analyzed using the statistical package for the social sciences. The results showed that only 12 out of 20 factors were significant. The experts then added three new factors, resulting in 15 significant factors classified into the three dimensions as follows: technology, organization and environment. Originality/value Limited studies have been carried out in the context of the O&G sector, even among developed countries such as Canada, the UK and Australia. These studies have focused on a limited number of factors for ERMS adoption targeting better utilization of human resources, faster and more user-friendly system responses and suitability for organizational ease. This paper explores the factors that may prove useful in adopting of ERMS in the O&G sector of developing countries, similar to Yemen.

Abstract:

Social recommender systems aim to support user preferences and help users make better decisions in social media. The social network and the social context are two vital elements in social recommender systems. In this contribution, we propose a new framework for a social recommender system based on both network structure analysis and social context mining. Exponential random graph models (ERGMs) are able to capture and simulate the complex structure of a micro-blog network. We derive the prediction formula from ERGMs for recommending micro-blog users. Then, a primary recommendation list is created by analysing the micro-blog network structure. In the next step, we calculate the sentiment similarities of micro-blog users based on a sentiment feature set which is extracted from users’ tweets. Sentiment similarities are used to filter the primary recommendation list and find users who have similar attitudes on the same topic. The goal of those two steps is to make the social recommender system much more precise and to satisfy users’ psychological preferences. At the end, we use this new framework deal with big real-world data. The recommendation results of diabetes accounts of Weibo show that our method outperforms other social recommender systems.

Abstract:

The European Rail Traffic Management System (ERTMS) will have an impact on the train driving task and the behaviour of the train drivers. This paper presents a part of the final study of the series of studies that have been conducted as part of a three-year research project, which investigated the effects of ERTMS on the behaviour of the train drivers. In recent times, a number of models of train driving have been developed in order to inform the design of the train driving technology and understand the implications of the design of the train driving task on the performance of the drivers and their behaviour. An expert knowledge elicitation study was conducted to evaluate the existing train driving models and to generate a guidance on human factors for the future ERTMS train driving models. The study consisted of a workshop, which was conducted using the rail human factor experts who have been directly involved with the projects examining ERTMS. The current train driving models were evaluated and ideas were generated as to how these should be shaped in the future to include systems such as ERTMS. The findings of the study contributed to bridging the gap between the theoretical understanding of the cognitive strategies of the train drivers and the practical implementation of novel technologies by the rail industry.

Abstract:

Abstract Purpose Given ophthalmology residency programs are transitioning to include the internship year, either through “joint” or “integrated” 4-year programs, we set out to identify applicant preferences regarding the match and their experiences with two residency application systems: (1) the Central Application Service (CAS) and (2) the Electronic Residency Application Service (ERAS). Design This study is designed as a retrospective repeated cross-sectional survey. Methods A 15-question online survey was sent to 196 and 461 applicants to the 2019 and 2020 ophthalmology match cycles, respectively. Questions from the survey assessed user experiences with specific components of both application services and evaluated preferences regarding the future of the ophthalmology match. Results Responses were received from 208 (32%) applicants. A majority of users had positive experiences with both application services; for CAS, 162 (78%) applicants had a positive experience, compared with 111 (53%) for ERAS. When compared directly, applicants favored the CAS (60%) to ERAS (21%). Furthermore, 108 (52%) respondents stated that they would prefer ophthalmology continue to use both the CAS and ERAS, while 47 (23%) respondents indicated a desire for the CAS to become the only application system for both matches. Conclusion Although half of all respondents prefer that both the CAS and ERAS systems are utilized for the match process, many express a desire for a single matching program. As ophthalmology residency programs move to joint and integrated 4-year programs, the complexity of matching will increase. Further evaluation of applicant preferences during this transition phase is needed as applicants are required to apply to a variety of different joint and integrated internship and ophthalmology programs.

Abstract:

Binary mixtures of aniline with benzene, toluene, alkane, alkanol, or N,N-dialkylamide have been investigated in the framework of the DISQUAC model. The reported interaction parameters change regularly with the molecular structure of the mixture components. The model consistently describes a set of thermodynamic properties including liquidliquid equilibria, vaporliquid equilibria, and molar excess enthalpies. The two latter properties for ternary systems are well-represented by DISQUAC using binary parameters only (i.e., neglecting ternary interactions). A comparison of DISQUAC results and those obtained from the UNIFAC (Dortmund version) and ERAS models is also shown. The experimental molar excess enthalpies for binary and ternary mixtures are better described by DISQUAC than by UNIFAC. ERAS fails when representing molar excess enthalpies of those binary systems including methanol or ethanol. This may be due to the existence of strong dipolar interactions among aniline molecules as well as to effects related to the equation of state term, evaluated comparing molar excess enthalpies, and molar excess internal energies at constant volume. The study of the aniline systems in terms of the concentrationconcentration structure factor also underlines the importance of dipolar interactions in solutions with alkanes or alcohols, which may be due to the high polarizability of the aniline molecule.Key words: thermodynamics, mixtures, aniline, dipolar interactions, structural effects.

Abstract:

The concept of purpose gained prominence in organization theory in recent years but there are discrepant views of its meaning, which we review as evolving and different perspectives: economic theories of the firm; stakeholder approaches; integrative social contracts; and social mission. We elaborate these perspectives in terms of the ebb and flow of ideas and eras. Against these instrumental views, we revisit the work of Robert Cooper, namely the ever-open purpose of expressive organizations, and contrast this with fixist views of purpose in instrumental organizations. We engage with the logic of open purpose and sketch a way of rethinking purpose as a general orientation that constantly evolves and changes over time in interaction with its ecosystem.

Abstract:

The Enhanced Recovery After Surgery (ERAS) system is a collection of preoperative, intraoperative, and early postoperative measures. The primary goal of gynecological surgery is a rapid and uneventful recovery from oncological and standard procedures, particularly in patients over the age of 65. The goal is to achieve comparable results to those obtained with minimally invasive procedures. Certain features of the ERAS system are similar to those of standard surgical procedures. These are the measures taken to prevent thromboembolism and to promote early postoperative mobility. Anesthesia and postoperative analgesia are critical components of achieving the ERAS system's objectives. The ERAS protocol requires multimodal non-opioid postoperative analgesia, infiltration of the surgical wound with a local anesthetic, and avoidance of opioid analgesics. We discuss current data on patient management according to the ERAS protocol for anesthesia and analgesia in order to minimize the body's stress reactions, promote early mobility, and reduce postoperative complications. ERAS protocol has gained popularity in recent years in a number of centers, primarily in the United States and Europe, due to its direct impact on hospital stay length, healthcare costs, and benefits for patients, their relatives, and caregivers. Keywords: ERAS protocol; multimodal opioid-sparing analgesia; local infiltration anesthesia.
