Flexible decision support for sustainable development: the SUSTAIN framework model
Authors: Bang Salling Kim , Barfod Michael Bruhn , Ridley Pryn Marie , Leleur Steen
Published: October 2023

Sustainable transport planning necessitates a rethinking of traditional decision making. This is conventionally supported by cost-benefit analysis (CBA) that systematically quantifies and compares the various benefits and costs generated by a transportation project or policy. Generally, CBA has been found less useful for the handling and assessment of multiple, often conflicting objectives or criteria like environmental or social issues intrinsically difficult to quantify. Therefore, it is necessary to broaden the decision making process beyond merely economic factors. The Danish research project on Sustainable National Transport Planning (SUSTAIN 2012-2016) seeks, among other things, to develop a flexible decision support model (tool) to include and assess sustainability planning criteria in a socio-economic framework, which makes up the SUSTAIN Framework Model (SFM). The SFM comprises two parts, namely a process part consisting of stakeholder involvement and an analytical tools part consisting of an Excel-based software model. The latter employs the use of CBA, multi-criteria decision analysis and risk analysis techniques enabling the assessment of non-quantifiable impacts within a decision support context. The concept of a planning workshop is introduced as relevant for dealing with the various strategic elements not included in the CBA. Moreover, SUSTAIN is rooted in cross-disciplinary sustainability research that recognises that a transition towards sustainability must involve normative, analytical and strategic considerations to be successful. The paper concludes that the SFM can contribute to the analytical dimension. Thus, the framework model allows for the appraisal of planning criteria (indicator sets) in a socio-economic appraisal setting for national sustainable transport planning which enhances both the concept and principles of sustainable development while at the same time it provides a flexible decisionsupport tool for policy-makers.
Giving current and future generations a real voice: a practical method for constructing sustainability viewpoints in transport appraisal
Authors: Cornet Yannick , Barradale Merrill Jones , Barfod Michael Bruhn , Hickman Robin
Published: October 2023

Decisions to invest in large-scale transport projects typically extend beyond traditional costbenefit analysis. Multi-criteria analysis methods such as multi-actor multi-criteria analysis (MAMCA) have been proposed to assess wider economic effects and long-term environmental impacts from various stakeholder perspectives. However, there is no standard practice for appraising transport projects against sustainable development objectives. In order to give future generations a voice in decisions that will impact them, this paper extends the MAMCA methodology to make various actors and a “sustainability viewpoint” explicit. A dual-approach method for constructing sustainability viewpoints in transport appraisal is proposed. The method juxtaposes an expert-based approach with a principle-based approach. In the former, sustainability experts are asked to prioritise criteria for project assessment. In the latter, criteria weights are calculated based on sustainability theory (“strong” and “weak” sustainability). Together, these viewpoints are intended to inform decision-making. The appraisal of HS2 Phase I, a high-speed rail project in the UK, is used to demonstrate the proposed method. It is found that all three variants of the sustainability viewpoint result in project preferences that are similar to each other, but different from those of other transport professionals. The paper concludes by arguing for the explicit inclusion and triangulation of sustainability viewpoints in transport appraisal on a multi-actor basis. One practical recommendation from the MAMCA process is the need to hire more transport planners with sustainability experience into government planning agencies.
Under which conditions is a PPP relevant for public spending?
Authors: Bonnafous Alain , D’Arcier Bruno Faivre
Published: October 2023

Public authorities increasingly involve the private sector in financing, building and operating new infrastructures. Many reasons are usually given to justify private sector involvement. One of them claims that private operators can manage project construction and operation more efficiently. Nevertheless, whether a public or a private operator, there is a target IRR, very close to the standard notion of Weighted Average Capital Cost (WACC), which is higher in the case of the private alternative because it must also include the operator's profit. The fundamental issue is the result of two opposite effects: on the one hand, the effect of the higher efficiency of the private operator; on the other hand, the effect of a lower WACC for the public operator. This paper proposes a model of the determination of the need of public financing which formalizes these two effects and allows analysing the conditions under which the PPP would be advantageous for the public finances. Simulations estimate the efficiency gain from private operators needed to compensate their higher WACC. Results confirmed the so-called ‘paradox of financial profitability’: recourse to PPP is more relevant for public funds when the profitability of the project is lower.
Capital structure and firm performance
Authors: Özcan İsmail Çağrı
Published: October 2023

The privatisation and liberalisation waves have been increasing the number of private companies in the aviation industry. This, in turn, necessitates new policy analyses on major financial decisions regarding capital structure, corporate governance and investments. Among these major topics, the research about the association between capital structure and financial performance of the aviation companies largely focuses on the airlines. But a comparable analysis for the airport companies is less explored. The goal of this study is to contribute to the literature by analysing how the capital structure of the publicly traded airport companies affects their profitability and market valuation. Using an unbalanced panel data sample of 29 publicly traded airports from 20 countries over the 1989-2017 period, our findings suggest that higher total and long-term leverage tend to decrease return on assets whereas they are positively associated with return on equity.
Mobility impacts of automated driving and shared mobility

Published: October 2023

This paper presents a model specifically developed to explore the mobility impacts of connected and automated driving and shared mobility. It is an explorative iterative model that uses an elasticity model for destination choice, a multinomial logit model for mode choice and a network fundamental diagram to assess traffic impacts. To the best of the authors’ knowledge, it is the first model that combines a network fundamental diagram with choice models. A second contribution is the inclusion of automated vehicles, automated (shared) taxis, automated shared vans and new parking concepts in the model as well as the way in which they affect mobility choices and traffic conditions. The insights into the direct mobility impacts are the third contribution. The short computation time of the model enables exploration of large numbers of scenarios, sensitivity analyses and assessments of the impacts of interventions. The model was applied in a case study of the Dutch Province of North-Holland, in which the potential impacts of automated and shared vehicles and mitigating interventions were explored. In this case study, four extreme scenarios were explored, in which 100% of the vehicles have SAE-level 3/4 or 5 and people have a low or high willingness to share. The extremes were chosen to get insights into maximum effects. The results show that if automated vehicles and sharing are accepted, it is likely that there will be considerable changes in mobility patterns and traffic performance, with both positive and problematic effects.
Inter- and Intrapersonal variation in destination choice
Authors: Chowdhury Saidul , La Paix Lissy , Geurs Karst
Published: October 2023

This paper examines spatial-temporal inter- and intrapersonal variation in destination choice, based on longitudinal smartphone data for the Netherlands. Mixed logit destination choice models were estimated using two years of data (2014 and 2015) from the Dutch Mobile Mobility Panel, in which over 68,000 trips for 442 respondents were recorded with a smartphone app during an annual four-week measurement period. A distinction was made between trips to compulsory activities (such as work) and trips for discretionary purposes (such as recreation) as they are associated with different trip characteristics. Discrete destination alternatives were defined based on individuals’ behaviour in terms of repeatedly visited destinations and the statistical distribution of a spatial repetition index. The model results show that intrapersonal variation in destination choice, departure time and mode choice was relatively high for less frequently visited locations, which indicates novelty-seeking behaviour in destination choice. Furthermore, we found a strong connection between activity, departure time, and destination choice. And, mode choice and departure time choice were highly repetitive for destinations visited repetitively (e.g. work), but not for discretionary activities.
Serious games as research instruments – Do’s and don’ts from a cross-case-analysis in transportation
Authors: Freese Maria , Lukosch Heide , Wegener Jan , König Alexandra
Published: October 2023

Serious games as research instruments are seen as a special type of participatory modelling, allowing a researcher to observe the behaviour and decisions taken by players. Yet, games have their own dynamics and come with certain challenges when used as a research instrument. This article reports on specific challenges in using games as research instruments in the domain of transportation. Therefore, three digital games from the transportation sub-systems freight transport, airport management and public transport are presented. The cases are analysed according to the challenges faced during the phases of requirements analysis, design, implementation, usage as research instrument, and evaluation. Based on this cross-case analysis of the research games, Do’s and Don’ts as well as practical recommendations are derived to support researchers and practitioners in applying serious games as research instruments in transportation. The new ReDIRE-framework to analyse serious games for research purposes is presented for this aim. Design guidelines resulting from our contribution can be helpful for game designers and researchers alike.
Choosing Suitable Indicators for the Assessment of Urban Air Mobility: A Case Study of Upper Bavaria, Germany
Authors: Al Haddad Christelle , Fu Mengying , Straubinger Anna , Plötner Kay , Antoniou Constantinos
Published: October 2023

Technological advances are disrupting mobility patterns and transport technologies, both on the ground and in the air. The latter has been recently observed in the research community of urban air mobility (UAM). Research in this area has studied several areas of its implementation, such as vehicle concepts, infrastructure, transport modeling, or operational constraints. Few studies however have focused on evaluating this service as an alternative among existing transportation systems. This research presents an approach for the selection of indicators for a multi-criteria analysis for the assessment of UAM, in a case study of Upper Bavaria, Germany. A 5-stage approach is showcased including an expert assessment for the relevance and feasibility of indicators, based on two rating scales. A threshold for selection is presented, applied and validated for both scales. The results included a list of indicators for assessing the potentials of UAM integration to existing public transportation systems; the chosen indicators were then compared against existing ones for sustainable urban mobility. A high match between resulting indicators and previous ones further validate the results, and suggest that there is a need for an iterative approach in the assessment of disruptive transport technologies.
Departure Time Choice and Bottleneck Congestion with Automated Vehicles: Role of On-board Activities
Authors: Pudāne Baiba
Published: October 2023

It is widely expected that automated vehicles (AVs) will revolutionise travel experience by better facilitating various on-board activities. While these activities could make travel more pleasant, as is often supposed, they could also affect daily schedules, the related travel choices, and finally, the aggregate travel patterns – possible influences that are still insufficiently studied. For example, a morning commuter deciding to perform some home or work activities during travel, instead of at home or work, could also reconsider his departure time to work. More such travellers together could reshape traffic congestion. This paper models exactly this scenario. It formulates new scheduling preferences, which account for home and/or work activities during morning commute, and uses these (1) to analyse the optimal departure times when there is no congestion, and (2) to obtain the equilibrium congestion patterns in a bottleneck setting. If there is no congestion, it is predicted that AV users would depart earlier (later), if the on-board environment supports their home (work) activities. If there is congestion, AV users that perform home (work) activities during travel skew the congestion to earlier (later) times, and AV users that perform both activities increase both early and late congestion. Engaging in any activity during travel worsens congestion, at least when assuming that AVs do not increase bottleneck capacity. If future AVs would be specialised to support only home, only work, or both home and work activities, and would do so to a similar extent, then ‘Work AVs’ would increase the congestion the least.
Future Urban Charging Solutions for Electric Vehicles
Authors: Villeneuve Dominic , Füllemann Yann , Drevon Guillaume , Moreau Vincent , Vuille François , Kaufmann Vincent
Published: October 2023

The numbers of electric vehicles (EV) will increase as many countries perceive EVs as a solution to reduce the emissions of transportation and therefore incentivize their adoption. However, the deployment of public charging infrastructure is lagging behind that of EVs, which represents a potential barrier to their wide-scale adoption. The objective of this paper is to develop a comprehensive overview of potential EV charging solutions to be deployed in urban areas. Using a micro-Delphi approach, experts from transport, energy and urban planning were consulted and identified 15 realistic options for charging electric vehicles in urban environments by 2035. The solutions range from purely technical to more service oriented. Most of these solutions already exist today, although some remain at a very early stage of deployment. The five most likely options were on-street public charging points, charging at work, fast-charging stations, using building domestic plugs and semi-fast charging in public areas. When combined with the typical mobility and residential profiles, our results show that EV drivers will most likely rely on a mix of solutions, when they have no home chargers. As such, no breakthrough or major shift is expected in charging infrastructures, rather a scale-up of existing solutions. Our analysis concludes that urban charging options will be numerous and no single solution is expected to dominate as users with different EV user profiles will charge at different times and locations.
Multi-agent programming to enhance resiliency of earthquake-prone old metropolitan areas by transit-oriented development under public-private partnership
Authors: Soleimani Hojjatollah , Poorzahedy Hossain
Published: October 2023

Deteriorated urban areas in large cities have poor living standards, are inaccessible and small-sized, and have unstable building structures. Earthquake hazards may turn such situations into human disasters. In most cases, neither the governments nor the owners of these properties have enough budgets for renovating them. The purpose of this paper is to take advantage of Transit Oriented Development concepts to simultaneously solve two major urban area problems: (a) renovation of deteriorated urban areas and prevention of urban sprawl, and (b) design of transit network and promotion of transit-oriented development to reduce traffic congestion, pollution, and other unwanted outcomes of the extensive automobile use in large metropolitan areas. This paper proposes a bilevel multi-agent programming in which each agent maximizes the respective benefits while being subjected to the results of the decisions by others. We formulate the problem and solve it by a novel meta-heuristic algorithm. After analyzing the set of solutions to a test problem, we apply the algorithm on this rather large, real case urban area, and discuss the results. The solution results indicate that the proposed methodology: (a) reduces the total travel time in transportation networks of the city, (b) turns the deteriorated urban developments into a new and attractive environment, (c) provides a profitable investment for the construction industries in the context of Build-Operate-Transfer scheme, and (d) upgrades urban life for the city in general, and alleviates earthquake hazards for the inhabitants of the deteriorated urban areas, in particular.
Impact of COVID-19 lockdown on commuting
Authors: Shibayama Takeru , Sandholzer Fabian , Laa Barbara , Brezina Tadej
Published: October 2023

We carried out an international online survey about changes in everyday mobility during the COVID-19 outbreak in 21 languages, collecting more than 11,000 responses from more than 100 countries. In this paper, we present our analysis about commuting travels of the responses between 23 March and 12 May 2020 from the fourteen countries with 100 or more responses, namely Austria, Brazil, Bulgaria, Czechia, Germany, Hungary, Iran, Italy, Japan, Malaysia, Slovakia, Slovenia, Thailand, and the UK. Home office is used typically by between 40% and 60% of working respondents. Among people with workplaces with possibility for home office, the percentage is between 60% and 80%. Among people with workplaces where presence is essential, the percentage does not typically go beyond 30%. This result potentially implies an ultimate magnitude of a strong home office measure. Among those who continued to commute but switched commuting transport modes from public transport to others, the COVID-19 infection risk in public transport is the reason that is most often referred to, but many of those who changed to private cars and to bicycles report reduced travel time, too. Measures to encourage the use of active travel modes where possible are strongly recommended, as this would potentially mitigate undesirable modal shift towards private motorized modes triggered by perception of infection risks while travelling with public transport.
Analysis of convergence in transport infrastructure: a global evidence
Authors: Saba Charles Shaaba , Ngepah Nicholas , Odhiambo Nicholas Mbaya
Published: October 2023

This study investigates the convergence in transport infrastructure for 102 countries spanning 1990-2018 using Phillips and Sul econometric methodology. We constructed a transportation infrastructure by a composite index of transportation computed via principal component analysis (PCA). Our findings suggest the presence of panel convergence at the global level, while the income groups exhibited panel divergence. The results obtained from the iterative testing procedure suggest that the sub-groups exhibited convergence and divergence features. Overall, this study finds that the process of convergence in transportation reflects the desirable emanations of transportation policies sharing possible similar characteristics, at least to some extent, across the globe.
Curbing cost overruns in infrastructure investment
Authors: Park Jung Eun
Published: October 2023

Infrastructure projects around the world have long been notorious for exceeding their budgets.  To address persistent cost overruns, the American Planning Association urged planners to adopt reference class forecasting alongside traditional methods but the practice has not caught on in the U.S.  Conversely, the U.K. adopted Kahneman’s Nobel Prize-winning theory to challenge biases in human judgment and mandated reference class forecasting for major projects in 2003.  Has reference class forecasting, originally developed to rectify honest mistakes, brought the promised success in the public sector wherein political pressure is significant?  Through before-and-after and with-and-without comparisons of 107 major projects, this empirical study examines the practical relevance of reference class forecasting for infrastructure investments.  A before-and-after comparison reveals that the average cost overrun declined from 38% to 5% following the introduction of reference class forecasting.  A with-and-without comparison also demonstrates that the U.K. surpassed its targeted probability of completing projects within budget by 12% using reference class forecasting, whereas the U.S. underperformed by 17%.  Thus, reference class forecasting has engendered notable improvements in estimation in the U.K.  This empirical study demonstrates the benefits of supplementing or replacing the current forecasting method.  The findings can be used to reduce substantial financial risks for the government as well as social and economic welfare losses for society.
Tracing the Effects of the Covid-19 Pandemic on Car Usage in Germany - an Analysis of the German Mobility Panel
Authors: Ecke Lisa , Magdolen Miriam , Chlond Bastian , Vortisch Peter
Published: October 2023

Being a vast external influence, the COVID-19 pandemic causes major changes in travel behavior on the individual level. This exceptional situation and the political measures such as the lockdown lead to decreased overall travel demand and shifts in mode choice. To understand these effects, the analysis of car usage in private households offers explanatory insights. To this aim, this study provides a differentiation of car usage before and during the COVID -19 pandemic in spring 2020. Furthermore, insights into structural changes of car usage in private households based on German Mobility Panel data are presented. The results show that during the COVID -19 pandemic car usage was affected, and overall mileage decreased. Especially newer cars with large cubic capacity show a large decrease in mileage by 39 % between 2019 and 2020. In addition, we see that the type of car usage (business/private) and the household characteristics are related to different magnitudes of change in car usage. Overall, it becomes evident that examining identical households and cars before and during the pandemic allows for a deeper understanding of the impacts of the COVID -19 pandemic.
Flight Delays in Germany: a Model for Evaluation of Future Cost Risk
Authors: Abadie Luis Mª , Galarraga Ibon , Ruiz-Gauna Itziar
Published: October 2023

Air traffic has been increasing in Germany over the last decades reaching in 2018 an all-time high with more than 3 million flights. This increase has led to a rise in delays, which generate different costs to airlines, passengers, and Air Navigation Service Providers. This paper focuses on understanding and predicting these costs. For this purpose, a stochastic modelling method is proposed to estimate future air traffic, delays and the cost of future delays. The model allows to better understand what the full distribution of the delay costs may look like. To that end, the paper analyses 1,826 daily items (from 1/1/2014 to 12/31/2018) with information of air traffic and delays for German airspace. Findings suggest that overall mean delay costs for 2019 may be up to 280 million €, while in the 5% worst cases this value could go up to an average of 319 million €.
Comparative mode choice analysis of university staff commuting travel preferences
Authors: Moslem Sarbast , Duleba Szabolcs , Esztergár-Kiss Domokos
Published: October 2023

Surveying citizen preferences on transportation modes when commuting is a major issue in urban transport planning. Most of the current methods approach the problem through the attributes of choices thus forecasting the demand indirectly. This paper aims to analyze a survey of commuting students and university staff by two direct preference models: the Analytic Hierarchy Process and the Best-Worst Method. Both techniques are based on pairwise comparisons; consequently, the commuting transport alternatives can be directly compared with each other, and the results are comparable, too. However, the two methods differ in the number and the nature of comparisons and in the consistency check, thus they can be regarded as competitors. A real-world case study on commuting student groups provides a better understanding of the proposed methodology. As a result, it can be stated that despite their low utilization in the transportation field, both the Analytic Hierarchy Process and the Best-Worst Method are applicable to mode choice preference surveys, and they produce comprehensive final outcomes. Therefore, the well-known tools of mode choice can be extended by Multi-Criteria-Decision-Making techniques to increase the efficiency of transport demand prediction. The extension is beneficial to avoid the bias of other methods in converting attribute evaluations to real mode choice decision, as both models, especially the Best-Worst approach, requires less cost and time than the mainstream techniques.
The impact of self-driving cars on the national transport system: an assessment for Belgium
Authors: Franckx Laurent
Published: October 2023

We study how full automation of the car fleet affects traffic volumes, congestion, and fuel consumption at the country level in Belgium. The central scenario in this paper looks at the combined effect of a lower opportunity cost of travel time, an increase in the acquisition price of cars by 20%, a decrease in insurance costs by 50% and a decrease in fuel consumption per km by 10%. The improvement in fuel efficiency always dominates the increase in acquisition costs, and average monetary costs decrease. Overall car travel increases by 21 up to 26%. Despite the improvement in fuel efficiency, total fuel consumption for diesel and gasoline increases by 5 up to 10%. The impact on the speed of road modes is highly location specific. A sensitivity analysis revealed that there is a threshold improvement in fuel efficiency where the “rebound effect” is nullified. To counteract the effects of full automation on total demand for car travel, a road charge close to 20 EUR cent per km would be needed.
Locating Automated Parcel Lockers (APL) with known customers’ demand: a mixed approach proposal
Authors: Ottaviani Filippo Maria , Zenezini Giovanni , De Marco Alberto , Carlin Antonio
Published: October 2023

Logistics Service Providers (LSP) are increasingly adopting Automated Parcel Lockers (APLs) to mitigate the operational pressure of last-mile logistics. The optimal location of APL stations is key for reaching customers’ demand while keeping the investment reasonable. Previous studies developed optimization algorithms and applied them to virtual instances of the problem, lacking applicability to real-life situations encountered by LSPs who aim to serve an urban area with such technology. This study proposes a novel solution to the APLs location problem by combining mixed-integer linear programming and greedy heuristics algorithms. The study tested the propose solution on real customers’ demand data related to Turin, Italy. Results show that covering 90% of the estimated potential demand requires 10 to 11 APLs, on average. The adopted approach enables finding an optimal solution grounded in a real geographical context without requiring time-consuming optimization.
Interpretative Phenomenological Analysis of Attention Deficit Hyperactivity Disorder in Adolescents
Authors: KÖROĞLU Arif Erdem , AKTAN Zekeriya Deniz
Published: October 2023

Current research on attention deficit hyperactivity disorder (ADHD) is generally based on quantitative methodology. This indicates a lack of information on how ADHD individuals explain this phenomenon, and what they experience. The aim of this research is to reveal how attention deficit hyperactivity disorder is experienced in adolescents and how adolescents explain this phenomenon. The participants in this study were ten adolescents aged 11-18 who were diagnosed with ADHD and did not have a comorbid diagnosis. Participants were interviewed through a semi-structured interview form. The interviews were conducted and recorded on an online platform, and a transcript of the voice recording of each participant was then created. The texts obtained from the transcripts were analyzed with an interpretative phenomenological analysis. As a result of the analysis, the following themes were found: Academic difficulty, normalizing and affirming the diagnosis, living with undesirable emotions and behaviors, and negative social experiences. The findings reveal that the ADHD-related experiences of adolescents and their explanations for the ADHD diagnosis are not of a single nature. Instead, they were also perceived in a positive light as well as negative. The results reveal that the awareness of professionals and families who have contact with ADHD-diagnosed adolescents should be raised, and interventional and motivational programs directed at ADHD treatment-related negative experiences of adolescents can be organized.
Effects of Relationship-Centered Obsessive Compulsive Symptoms and Difficulty in Emotion Regulation on Psychological Well-Being in Young Adults
Authors: MISIRLI Melis , KARADAYI KAYNAK Gamze
Published: October 2023

This study aims to examine the relationships between emotion regulation difficulties, relationship-centered obsessive-compulsive symptoms, and psychological well-being. The study's second objective is to investigate the mediating role of emotion regulation difficulties in the relationship between relationship-centered obsessive-compulsive symptoms and psychological well-being. The participants comprised 191 individuals (152 females and 39 males) aged 18 to 25 (M=21.96, SD=1.78) who lived in Turkey and had been in a romantic relationship for at least one month between 2021 and 2022. In the study, participants were administered a Personal Information Form, the Short Form of the Emotion Regulation Difficulties Scale, the Relationship Obsessive Compulsive Inventory, and the Multidimensional Psychological Well-Being Scale. The results indicate a significant positive relationship between relationship-centered obsessive-compulsive symptoms and emotion regulation difficulties. Moreover, a significant negative relationship was found between emotion regulation difficulties and relationship-centered obsessive-compulsive symptoms and psychological well-being. Additionally, the variables were found to significantly predict psychological well-being in a negative direction, explaining 22% of the variance. According to the mediation analysis, emotion regulation difficulties play a partial mediating role in the relationship between relationship-centered obsessive-compulsive symptoms and psychological well-being. This study is expected to contribute to understanding the etiology and treatment of romantic relationship-centered obsessive-compulsive disorder.
How to Regulate Anger? Using Expression, Problem Solving, and Distraction Strategies
Authors: ŞAHİN İrem , AKIN SARI Burçin
Published: October 2023

The main purpose of this study was to examine the effects of anger regulation on emotion regulation strategies applied through writing tasks. In this respect, a scenario that would trigger the anger was created. Levels of anger regulation were then evaluated by examining the effects of expression, problem-solving, and distraction strategies applied through writing tasks. The change in anger regulation was evaluated in terms of positive affect, negative affect, valence, and arousal values of emotion. In addition, the levels of effectiveness of these emotion regulation strategies were compared with each other. The sample of the study consisted of 152 female university students (for age; M =19.71, SD = 1.38). The Positive and Negative Affect Scale, Emotion and Arousal Assessment, and Emotional Valence Assessment Form were used as data collection tools. It was found that all three emotion regulation strategies had significant effects on negative affect and arousal. The most effective strategy for negative affect was distraction (M =14.44, SD = 4.83), while the least effective was expression (M =27.38, SD = 8.01). Finally, the most effective strategies for arousal were distraction and expression with problem-solving, and there was no significant difference between the effectiveness of these two strategies (M =3.40, SD = 0.80; M =3.54, SD = 1.09, respectively), while the least effective strategy was expression (M =4.11, SD = 1.07).
The Biopsychosocial Model and Scientific Deception
Authors: McLaren Niall
Published: October 2023

Mainstream psychiatry is unable to decide on its model of mental disorder. While the great bulk of research is biologically oriented, many practitioners prefer a more holistic model integrating biological, psychological, and social factors. The “biopsychosocial model” attributed to George Engel appears to offer theoretical support, but the evidence is that it does not exist in any form suitable for science. This puts psychiatry in an invidious position, exposed to allegations of misconduct with no obvious defense.

Published: October 2023

El propósito de este artículo es interrogar la noción de auditorio. Con ello se busca el tránsito de su carácter normativo-validador hacia un rol más activo, susceptible de aportar a la relación argumentación-formación crítica. El método empleado se define como relacional interpretativo de corte teórico que integra aspectos hermenéuticos y fenomenológicos. A partir de esta conjunción es posible suspender al auditorio para despojarlo de algunos de sus supuestos. Como resultadosse presentan los rasgos del auditorio universal que sugieren una lectura alternativa de la idea de audiencia. Además, se advierte que está atravesada por una serie depresunciones que no suelen cuestionarse. Se concluye que el auditorio, como construcción del mundo de la vida, no se subscribe en un ámbito fijo e inmutable, sino que admite el desplazamiento de sus límites y funciones.

Guía de implementación de un Smart Contract como propuesta de mejora del proceso de selección de subcontratistas de acabados para proyectos de viviendas multifamiliares en Lima llevados a cabo por empresas constructoras medianas a través de la aplicación de la tecnología blockchain
Authors:   , Janampa Matta Josue Nahum , Pinedo Grandez Jean Pierre Rony
Published: October 2023

La industria de la construcción se ha convertido en el gran motor de la recuperación económica mundial tras los efectos de la COVID-19, siendo los proyectos de viviendas multifamiliares la encargada de impulsar el crecimiento a corto plazo gracias a la constante demanda de espacios residenciales. En ese sentido, diversos retos como las nuevas tecnologías, la complejidad de los proyectos y un entorno cada vez más competitivo, obligan al contratista principal a subcontratar entre el 80-90% de las actividades, especialmente en la especialidad de arquitectura, convirtiendo a la subcontratación en un proceso requerido en todo proyecto. Sin embargo, uno de los principales riesgos de la subcontratación es la inadecuada selección del subcontratista, lo que conlleva a riesgos respecto al tiempo, costo y calidad del proyecto. Por tal motivo, la presente investigación pretende mejorar la selección del subcontratista de acabados mediante la elaboración de una guía de un proceso de selección para empresas constructoras medianas, en el que se incorpore un Smart Contract para contribuir a la confianza en dicho proceso, gracias a su aporte en la seguridad, transparencia, trazabilidad y automatización que proporciona la tecnología Blockchain. Para ello, se implementa la propuesta en un proyecto de vivienda multifamiliar mediante una simulación de un proceso de selección, en donde se obtiene un grado de contribución a la confianza del 100% percibida por el contratista. Finalmente, se valida la guía con expertos del rubro para que pueda ser empleada en futuros procesos de selección de subcontratistas de acabados en empresas constructoras medianas.

Introducción: El Internet constituye un medio de comunicación masiva que puede intervenir en diversos sectores; por ejemplo, la informática, la educación, el desarrollo de recursos humanos y en salud. Los pobladores adultos sanos y enfermos, son más susceptibles a buscar por internet datos sobre su padecimiento lo que podría influir en sus decisiones en relación al manejo de su patología. En vista de la escasez de estudios locales decidimos realizar este trabajo con el objetivo de determinar si los pobladores adultos enfermos atendidos en un centro hospitalario son más susceptibles a buscar por internet datos sobre su padecimiento y de esta manera tener en cuenta este medio como parte del proceso de atención del paciente Metodología: se realizó estudio analítico transversal, incluyéndose a los pacientes adultos que ya fueron atendidos por consulta externa en el Hospital Edgardo Rebagliati Martins, entrevistados en la puerta de ingreso y / o salida Conclusiones: En primer lugar, observamos que el 91,88% de nuestra población de estudio utiliza el internet para buscar información de salud. En segundo lugar, se puede observar que a mayor uso de internet menos valoran el internet como buena fuente de salud. Esto se debe posiblemente a la inmensa información o los datos erróneos que encontraron en internet y por la falta de una página web para los pacientes de fácil acceso y de fácil comprensión.

This study's objective is to investigate the relationship between the quality of sharia-compliant customer service and the degree of customer loyalty, with the satisfaction of customers serving as a moderating variable. The participants in this study were customers who had previously utilised the services provided by sharia inns in Mojokerto. The research was carried out in a number of sharia inns in Mojokerto. The data analysis technique uses Regression Path Analysis. The empirical research results prove that service quality influences customer loyalty and customer satisfaction, and customer satisfaction influences customer loyalty. The results of the study also found that customer satisfaction mediates the effect of service quality on customer loyalty. In an increasingly competitive business era, service quality and customer satisfaction play a very important role for a company's success. Good service quality and customer delight can help build long-term relationships with customers. When customers are satisfied with the services provided, they tend to remain loyal and not switch to competitors.

Fasulye genotiplerinde çok değişkenli istatistiksel yöntemler ile tohum fiziksel özelliklerinin karakterizasyonu
Authors: KARAMAN Ruziye
Published: October 2023

Amaç: Tohumların hasat, harman, işlenmesi, sınıflandırılması ve depolanmasında tohumun fiziksel özellikleri büyük önem taşımaktadır. Bu nedenle çalışmada farklı büyüklük ve renkteki fasulye genotiplerinin fiziksel özellikleri kullanılarak çok değişkenli istatistik yöntemleri ile karakterizasyonun yapılması amaçlanmıştır.

Materyal ve Yöntem: Çalışma Isparta Uygulamalı Bilimler Üniversitesi Ziraat Fakültesi Tarla Bitkileri bölümü laboratuvarlarında 2021 yılında kurulmuştur. Araştırmada fiziksel özellik olarak tohumların uzunluğu, genişliği, kalınlığı, en-boy oranı, parlaklık (L*) değeri, aritmetik ortalama çapı, geometrik ortalama çapı, basıklığı, küreselliği, tohum hacmi, yığın hacim ağırlığı, gerçek hacim ağırlığı, porozite ve yüzey alanı özellikleri incelenmiştir. Çalışmada elde edilen veriler doğrultusunda korelasyon, temel bileşen analizi ve kümeleme ısı haritaları belirlenmiştir.

Araştırma Bulguları: Çalışma sonucunda fiziksel özellikler yönünden genel olarak Bolu’dan temin edilen G10 genotipi ön plana çıkmıştır. Korelasyon analizi sonucu genel olarak tohum uzunluğu, genişliği ve kalınlığı, aritmetik ortalama çap, geometrik ortalama çap ve tohum hacmi özellikleri arasında pozitif ilişki olduğu belirlenmiştir. TBA sonucunda incelenen özellikler ile ilgili olarak birbirinden bağımsız 3 tane temel bileşen ekseni elde edilmiştir. Elde edilen eksenlerin toplam varyasyonun %91.7’sini oluşturmaktadır. Kümeleme analizine göre ise, genotipler dört gruba, incelenen özellikler ise üç gruba ayrılmıştır.

Sonuç: Yapılan bu çok değişkenli analizlerin sonucunda belirlenen özelliklerin fasulye genetik materyalleri üzerine ıslahçılara pratik anlamda fayda sağlayacağı düşünülmektedir.

Objective: The objective of this study was to determine the effect of hazelnut husk released after production on some physical and biological properties, nutrient content, and hazelnut yield of hazelnut orchard soil.
Material and Methods: In experiments, each hazelnut ocak was planted at a 4.0 m x 4.5 m distance to form a parcel; Hazelnut husk was applied at doses of 0, 25, 50, and 75 kg/ocak in a randomized block design with three replications. In the first, second, and third years following the application, soil samples were taken after the hazelnut harvest in order to, determine some physical, chemical and biological properties, nutrient content, and hazelnut yields.
Results: Statistically, significant differences were determined in the organic matter (OM), penetration resistance (PR), bulk density (BD), soil respiration (SR), microbial biomass carbon (Cmic), total N, available P2O5, K2O and hazelnut yields (p<0.01) of the soil depending on the hazelnut husk dose applications. Depending on the application dose, hazelnut husk application increased the organic matter content of the soil by an average of 29.84% as compared to the control.
Conclusion: As a result of the positive changes in the physical and biological properties of the soils, increases were obtained in the applied doses in the total N, available P2O5, K2O, and hazelnut yields of the soils as compared to the control.
