To Green or Not to Green: The E-Commerce-Delivery Question

In an era in which e-commerce has become an integral facet of our lives, the delivery process has evolved into a vital part of online shopping. As the sole tangible interaction in an otherwise digital undertaking, it forms a decisive aspect of consumers’ e-commerce experience. In the face of the ever-growing prevalence of e-commerce, the ecological footprint left by delivery practices has emerged as a pressing concern. This focus is attributed not only to the environmental externalities resulting from e-commerce delivery but also due to the system’s inherent inefficiencies. As the primary beneficiaries of e-commerce, consumers form a pivotal force in driving sustainable delivery initiatives. This study embarks on an exploration of consumers’ attitudes toward environmentally friendly e-commerce-delivery practices. We aim to investigate whether consumers are willing to bear additional costs for assured green deliveries and identify which sustainable practices they perceive as most effective. A survey was conducted among e-commerce users to show their readiness to incur higher costs for green delivery and accept delayed deliveries if they supported sustainability. However, our findings reveal a conflicting scenario. While consumers display a readiness to opt for green deliveries, the price and speed of delivery emerged as more critical considerations. This study also uncovers significant discrepancies in attitudes towards green delivery based on demographic factors, such as gender and generation. Utilizing multivariate logistic regression, the study outlines the main factors that predict a willingness to pay for guaranteed green delivery. This study’s findings stress the need to balance the drive for speed and cost-effectiveness in e-commerce delivery with the urgency to adopt sustainable practices. It underscores the necessity for e-commerce platforms and logistics partners to take the lead in crafting and implementing innovative green delivery solutions while educating and incentivizing consumers to choose sustainable delivery options.

Minimap: An interactive dynamic decision making game for search and rescue missions.

Many aspects of humans' dynamic decision-making (DDM) behaviors have been studied with computer-simulated games called microworlds. However, most microworlds only emphasize specific elements of DDM and are inflexible in generating a variety of environments and experimental designs. Moreover, despite the ubiquity of gridworld games for Artificial Intelligence (AI) research, only some tools exist to aid in the development of browser-based gridworld environments for studying the dynamics of human decision-making behavior. To address these issues, we introduce Minimap, a dynamic interactive game to examine DDM in search and rescue missions, which incorporates all the essential characteristics of DDM and offers a wide range of flexibility regarding experimental setups and the creation of experimental scenarios. Minimap specifically allows customization of dynamics, complexity, opaqueness, and dynamic complexity when designing a DDM task. Minimap also enables researchers to visualize and replay recorded human trajectories for the analysis of human behavior. To demonstrate the utility of Minimap, we present a behavioral experiment that examines the impact of different degrees of structural complexity coupled with the opaqueness of the environment on human decision-making performance under time constraints. We discuss the potential applications of Minimap in improving productivity and transparent replications of human behavior and human-AI teaming research. We made Minimap an open-source tool, freely available at https://github.com/DDM-Lab/MinimapInteractiveDDMGame .

Moral beacons: Understanding moral character and moral influence.

We introduce the concept of moral beacons-individuals who are higher in moral character than their peers and prominent within their social environment-and examine the degree to which moral beacons increase the moral awareness of their peers. Using data from cohorts of students in graduate business education across two universities, we applied theory and methods from organizational behavior, personality psychology, and social networks analysis to test two research questions about moral beacons. We used latent profile analysis of data from personality questionnaires and social network surveys completed by graduate business students at two universities (N = 502) to identify individuals classified as moral beacons. We used peer nominations and an in-class business case discussion exercise to assess moral influence. Latent profile analysis identified a latent class of moral beacons in our sample. These individuals received more nominations from their peers in end-of-class surveys as guides for moral thought and action and positively impacted the moral awareness of their peers in a discussion of a difficult business case about possible lead poisoning of employees, but did not significantly change their counterparts' moral awareness in a different case. These results provide promising initial evidence that moral beacons can be distinguished from their peers by both moral character and social prominence and can act as guides for others, at times encouraging greater consideration of the moral aspects of situations and decisions. As these results are the first of their kind, we encourage further replication and investigations of moral beacons and moral influence in other settings.

A Population-Informed Particle Filter for Robust Physiological Monitoring Using Low-Information Time-Series Measurements.

To present the population-informed particle filter (PIPF), a novel filtering approach that incorporates past experiences with patients into the filtering process to provide reliable beliefs about a new patient's physiological state. To derive the PIPF, we formulate the filtering problem as recursive inference on a probabilistic graphical model, which includes representations for the pertinent physiological dynamics and the hierarchical relationship between past and present patient characteristics. Then, we provide an algorithmic solution to the filtering problem using Sequential Monte-Carlo techniques. To demonstrate the merits of the PIPF approach, we apply it to a case study of physiological monitoring for hemodynamic management. The PIPF approach could provide reliable beliefs about the likely values and uncertainties associated with a patient's unmeasured physiological variables (e.g., hematocrit and cardiac output), characteristics (e.g., tendency for atypical behavior), and events (e.g., hemorrhage) given low-information measurements. The PIPF shows promise in the presented case study, and may have applications to a wider range of real-time monitoring problems with limited measurements. Forming reliable beliefs about a patient's physiological state is an essential aspect of algorithmic decision-making in medical care settings. Hence, the PIPF may serve as a solid basis for designing interpretable and context-aware physiological monitoring, medical decision-support, and closed-loop control algorithms.

Decision-Making Approach in Sustainability Assessment in Steel Manufacturing Companies—Systematic Literature Review

Sustainability is understood as a balanced integration of economic, ecological, and social aspects. Sustainable manufacturing can be considered one of the most important issues to address in the pursuit of sustainable development. The main purpose of the paper is to identify the most important directions of research to date and to indicate new and emerging areas of research concerned with the usage of decision-making methods in sustainability assessment in steel manufacturing companies. A systematic review was based on the publications indexed in the Web of Science and Scopus databases. In the analysis, the correspondence analysis and log-linear model were applied. To sum up, this study examines decision-making modalities and sustainable performance in terms of approaches that influence sustainability in steel manufacturing. Firstly, the study determined key decision-making aspects, such as the appropriate material identification for the manufacturing process and material labeling for the manufacturing process, which is essential for sustainable metal products. Secondly, the identification of sustainability indicators is considered vital in the hierarchical process as their integration is essential for the decision-making process and its outcome. Furthermore, system efficiency and productivity, alongside increasing attention to environmental protection, have led to significant changes in all production systems. In addition, many factors play an important role in the selection of suppliers, such as increasing the importance of the environment, increasing the recycling rate of the products, and ensuring sustainability performance. However, companies in the steel manufacturing industry rely little on the application of decision-making to assess sustainability.

Ethical considerations in the prehospital treatment of out-of-hospital cardiac arrest: A multi-centre, qualitative study.

Prehospital emergency physicians have to navigate complex decision-making in out-of-hospital cardiac arrest (OHCA) treatment that includes ethical considerations. This study explores Danish prehospital physicians' experiences of ethical issues influencing their decision-making during OHCA. We conducted a multisite ethnographic study. Through convenience sampling, we included 17 individual interviews with prehospital physicians and performed 22 structured observations on the actions of the prehospital personnel during OHCAs. We collected data during more than 800 observation hours in the Danish prehospital setting between December 2019 and April 2022. Data were analysed with thematic analysis. All physicians experienced ethical considerations that influenced their decision-making in a complex interrelated process. We identified three overarching themes in the ethical considerations: Expectations towards patient prognosis and expectations from relatives, bystanders, and colleagues involved in the cardiac arrest; the values and beliefs of the physician and values and beliefs of others involved in the cardiac arrest treatment; and dilemmas encountered in decision-making such as conflicting values. This extensive qualitative study provides an in-depth look at aspects of ethical considerations in decision-making in prehospital resuscitation and found aspects of ethical decision-making that could be harmful to both physicians and patients, such as difficulties in handling advance directives and potential unequal outcomes of the decision-making. The results call for multifaceted interventions on a wider societal level with a focus on advance care planning, education of patients and relatives, and interventions towards prehospital clinicians for a better understanding and awareness of ethical aspects of decision-making.

Costs of oropharyngeal squamous cell cancer treatment in Finland

BackgroundOropharyngeal squamous cell carcinoma (OPSCC) can be treated with definitive (chemo)radiotherapy ((C)RT) or primary surgical treatment (PST) with or without postoperative oncologic treatment. The prognosis of OPSCC does not essentially depend on the treatment modality, which allows to consider secondary decision-making aspects such as treatment costs when recommending an individual treatment modality. We attempted to analyze the costs associated with definitive (C)RT and PST in the treatment of OPSCC in Finland.Materials and methodsWe included 73 patients diagnosed with OPSCC at the Helsinki University Hospital (HUS) (Helsinki, Finland) in 2019 and 2020. Treatment costs were defined as the costs incurred in the specialized medical care during the first 12 months after the diagnosis was established.ResultsDefinitive RT and definitive CRT were on a 1-year horizon associated with median costs of approximately 10 700€ and 13 300€, respectively; while, the median costs of PST equaled about 40 600€. The costs of definitive (C)RT mostly consisted of the costs of (chemo)radiotherapy sessions; while, the operating room costs and the costs of intensive care and stay on a ward drove the costs of PST.ConclusionsPST is associated with 2–3 times higher median costs than definitive (C)RT in Finland. The finding differs from the results previously reported in North America, which is related, e.g., to differences in the treatment practices as well as in the regulation of the health care systems.

The archerfish predictive C-start.

A very quick decision enables hunting archerfish to secure downed prey even when they are heavily outnumbered by competing other surface-feeding fish. Based exclusively on information that is taken briefly after the onset of prey motion, the fish select a rapid C-start that turns them right towards the later point of catch. Moreover, the C-start, and not later fin strokes, already lends the fish the speed needed to arrive at just the right time. The archerfish predictive C-starts are kinematically not distinguishable from escape C-starts made by the same individual and are among the fastest C-starts known in teleost fish. The start decisions allow the fish-for ballistically falling prey-to respond accurately to any combination of the initial variables of prey movement and for any position and orientation of the responding fish. The start decisions do not show a speed-accuracy tradeoff and their accuracy is buffered against substantial changes of environmental parameters. Here, I introduce key aspects of this high-speed decision that combines speed, complexity, and precision in an unusual way.

A novel fast intra algorithm for VVC based on histogram of oriented gradient

The latest Versatile Video Coding (VVC) standard incorporates a series of effective and complex new intra coding tools, which obtains superior coding efficiency than the High Efficiency Video Coding (HEVC). However, this makes the intra coding more complicated and time-consuming. A fast algorithm for VVC from two aspects of fast mode decision and fast partition decision is proposed in this paper. For the fast mode decision, the relationship between bins with Histogram of Oriented Gradient (HOG) and intra modes is created for the mode selection, decreasing the planar modes for SATD and RDO. Moreover, we analyze the maximum bins to determine the final modes, and we use the modes of left and upper blocks as a reference for the current CU, which can early terminate RDO. Moreover, a two-step fast partition algorithm is proposed based on HOG for fast partition decision, in which two thresholds are investigated to control the uniformity of textures. The proposed fast algorithm is implemented on the VVC test model, and the experimental results show that it can achieve 69.07% time savings with only 2.96% BDBR increases averagely, which outperforms other relatively existing state-of-the-art methods. Moreover, to convince the universality of our algorithm, we further implement our method in Fraunhofer Versatile Video Encoder (VVenc) and Fraunhofer Versatile Video Decoder (VVdec), which have five settings to control the trade-off between encoding quality and efficiency for intra coding. The fast intra mode decision algorithm and fast partition algorithm decrease the complexity of intra coding for both VTM and VVenc, which shows the efficiency and universality of the proposed fast partition and fast mode decision algorithms.

Utilisation du système d’information des ressources humaines (SIRH) dans l’entreprise: Cas d’un échantillon d’entreprises de la Région Souss-Massa au Maroc

The use of innovative tools in HRM is becoming more and more necessary to increase the efficiency of the HR function but also that of the organization. This is why today's organizations are increasingly resorting to the acquisition of HR solutions such as the human resources information system (HRIS). This tool, which often takes the form of an ERP or separate HR modules, is structured around administrative processes dedicated to keeping employee files, managing time and activities, payroll and benefits, etc., in order to focus on other HR activities with a higher value-added decision-making aspect such as GPEC, etc. The reason behind this study is to know the state of play in the use of the HRIS at the level of the Souss-Massa Region in Morocco. To do this, we have chosen to study a sample of companies in the private and semi-public sectors through a quantitative study based on a questionnaire which was carried out after seeing important aspects of previous studies on this subject. The survey concerned HR actors in these organizations. The main results of this research, mainly based on the CPA revealed that the HRIS is mainly focused on the traditional components such as payroll and benefits management, employee record keeping, time and activity management, recruitment and selection and monitoring and analysis of turnover.

Dança e cultura: Sentidos e significados sob uma perspectiva histórica

This paper aims at reflecting on dance as a component of culture in view of certain historically constructed meanings and senses. In the meantime, the challenge in this reflection is also to propose a connection with the topics: 1) Dance as an expression or as a denunciation of culture; 2) Dance as a confluence in an interart dialogue; and 3) Dance and Cultural Politics: From the Ancien Régime to the Mass Society. The methodology used for this exercise is bibliographical research. It allows us to take a brief historical look at dance since prehistoric times, to synthesize and to draw together what, in my opinion, are the most important and decisive aspects of the course of events towards a culture of the Western world. Such a journey allows us to understand dance not only as a purely physical/motor activity but also as a cultural component that even has its confluences with other artistic languages. One of the findings emerging from this reflection is that dance is a form of «syncretic language» which tells, reveals and unveils history, forms of society and culture.

Kebebasan Hakim dalam Melahirkan Putusan Progresif

Determining a decision is not easy and sometimes gives a difficult position for a judge, determining a judge's decision is required to carry out the technical juridical and procedural implementation of legislation. Therefore it becomes important to determine the conditions that must be owned by a judge related to his freedom in making progressive decisions. This research is a literature study to explore indicators that can produce a progressive decision that must be owned by a judge. The indicator that must be possessed is the independence of a judge, which is based on moral and ethical integrity, the transparency aspect of decisions is also a picture of freedom and progressiveness, besides that professionalism and intellectual ability are absolute requirements that are part of the basic things that a progressive judge must have.

Polarization in public attitudes toward end-of-life decisions in Israel - A cross-sectional study.

End-of-life (EoL) processes are a complex socio-normative and ethical phenomenon. This study aimed to generate a database of public opinion in Israel concerning EoL processes and decisions and to identify differences in attitudes across subgroups in the population, particularly based on experience as a family caregiver of a dying patient. This cross-sectional study was performed in late March 2022. The study utilized an online sample of 605 adults over the age of 50 including those who accompanied a loved one to their death in the last 3 years. Participants were requested to provide their opinions and attitudes on several aspects of EoL decisions, including truth-telling, medically assisted dying, EoL procedures, pre-death actions, and family caregivers' engagement. While only 27% and ∼30% of participants support artificial respiration or feeding (respectively) of terminally ill patients, 66% support analgesic treatment, even at the risk of shortening life. The data show an association between religiosity and agreement with life-extending procedures. For example, while 83% of seculars support medically assisted dying, only 59% and 26% of traditional and religious respondents support it. However, no statistically significant differences were observed in support of family involvement in EoL process in any sociodemographic variable. The results of this study suggest that the Israeli public is relatively polarized on several issues about EoL processes, specifically patient autonomy and medically assisted dying. Yet, at the same time, there is a consensus among the Israeli public about certain EoL elements, particularly the importance of family caregivers in the EoL decision-making process.

Assessment of selected environmental and economic factors for the development of electro-mobility in Poland

AbstractElectromobility is now widely recognized as a remedy for the growing level of greenhouse gas emissions from the transport sector. The result of this approach is the agreement of the European Commission with the member states regarding the achievement of CO2-free emission of the new fleet of passenger cars by 2035 through the use of battery electric vehicles. However, it should be emphasized that currently, not every country in the European Union has electricity sources with low CO2 emission (Proposal for a REGULATION… (EU) 2019/631), which in fact can contribute to a lower environmental effect than expected. The amount of environmental impact of a battery electric vehicle depends mainly on the type of energy mix of the country in which it is used. In view of the above, the first scientific objective of the article is a comparative assessment of environmental impact, using the LCA (Life Cycle Assessment), the phase of use of passenger cars with conventional drive in relation to battery electric vehicles consuming electricity from the power grid in Poland and in Italy. The results of the LCA analysis, phases of BEV use in Poland indicate a higher level of environmental impact in relation to ICE due to the generation of electricity, for the most part from hard coal. Nevertheless, in Poland, as in other EU countries, an electromobility support system is being implemented. The successful implementation of electromobility depends on the environmental awareness of BEV users. The scientific cognitive aspect of the BEV purchase decisions of the Polish society is carried out using a survey questionnaire with the use of a non-random selection of the research sample (convenient selection). The aim of this cross-sectional survey was to confront the results of the environmental impact of the BEV use phase with the knowledge of the Polish society, as well as to learn about purchasing factors (future and current users). The results of the survey questionnaire demonstrate the low level of knowledge of the Polish society on the impact of the BEV use phase in Poland. This can be the result of media coverage in which BEV is presented as ecological transport. The aim of the article is not to depreciate the environmental performance of BEVs, but to draw attention to the fact that, to a large extent, the environmental impact of the BEV use phase depends on the place of use (country), and precisely the type of energy mix of a particular country. The literature on the subject lacks the confrontation of the results of scientific research in the field of environmental impact assessment of the BEV use phase with the knowledge of the public on this subject. The research results can be used by decision makers to properly target the support for the development of electromobility in Poland, consisting primarily in increasing the availability of infrastructure for charging BEV and changing the energy mix to energy sources with a lower environmental impact.

Ethical Decision-Making in Law Enforcement: A Scoping Review

Decision-making in uncertain and stressful environments combined with the high-profile cases of police violence in the United States has generated substantial debates about policing and created challenges to maintaining public confidence and trust in law enforcement. However, despite the manifestations of reactions across the ideological spectrum, it is unclear what information is available in the literature about the convergence between ethical decision-making and policing. Therefore, an interdisciplinary scoping review was conducted to map the nature and extent of research evidence, identify existing gaps in knowledge, and discuss future implications for ethical decision-making in law enforcement. This review investigates the interaction between the job complexities of policing (psychological and normative factors) and aspects of ethical decision-making, synthesizing three distinct themes: (1) socio-moral dimensions impact the job complexities of police work, (2) lethal means and moral injury influence intuitive and rational decision-making, and (3) police wellness and interventions are critical to sustaining police readiness. Gaps in recruiting, training, and leadership and managerial practices can be broadly transformed to fundamentally emphasize officer wellness and a holistic approach to ethical practices, enabling police officers to uphold the rule of law, promote public safety, and protect the communities they serve.

The Importance of Trust in Cultivating Employee Loyalty and Productivity in a Remote Work Environment

Purpose: This study aims to interpret workers' desire, especially copywriters, to work from home while producing profitable results for the company and maintaining a competitive advantage. Theoretical framework: Motivation is an essential aspect of human decision-making because it motivates people to act, according to Abraham H. Maslow (2002). Motivation is an inner drive that guides a person's behavior and can be influenced by factors such as comfort, style, prestige, or a desire to fit in with others. Design/methodology/approach: This study uses a qualitative inductive reasoning-based exploratory technique to investigate individual experiences in the advertising industry during a pandemic. It uses a phenomenological paradigm. Creswell (2014) defines phenomenological research as a branch of economics, management, and psychology that describes participants' life experiences related to a phenomenon. Findings: Employee loyalty can be developed by trusting and respecting colleagues, which is essential for a pleasant work environment, especially when working remotely. Remote working has several benefits, including increased productivity, improved work-life balance, and cost savings for employees and businesses. Flexible work arrangements and focusing on employee time off can significantly impact employee loyalty, productivity, and overall competitive advantage. Research, Practical & Social implications: Trust and respect for their employees' time and well-being must be prioritized by transformational leaders, which can increase company loyalty, productivity, and growth. Originality/value: Trust and confidence in the company's leadership and mission can foster employee loyalty and a healthy work environment, even when working remotely.

Дискретная стохастическая модель гидродинамики потока

For the mathematical description of hydrodynamic conditions in industrial equipment, idealized models are usually used. Upon receipt, a number of simplifying assumptions are made, which, on the one hand, facilitate the use, and on the other hand, the Appearance of the adequacy of the model. All typical models of flow structures are deterministic and continual. At the same time, it became known that the real situation arises in the process of considering possible factors. This trend leads to the need for a wider application of probabilistic approaches to modeling technological processes and apparatuses using modern digital technologies. This article cancels an attempt to create a hydrodynamic model using probabilistic cellular automata. In the model of occurrence, there is one reason for two flow velocities, a decision on the occurrence of a pressure drop, and the other is due to random walks of microvolumes of a moving medium. The described procedure for creating a model contains the results of its use. In particular, the results of modeling of motion trajectories in rare cases, the phenomena of their general movement and detection in rare zones were found. The article presents the results of a comparison of a discrete stochastic model with the types of a diffusion model, in terms of reflecting the physical essence of current flows, the possibilities of determining parameter models, and ease of use. The decisive aspects of the new model, its advantages and revolutions are shown. Possible areas of application of the obtained model. Under investigation are the results of simulation modeling using the proposed model, which reveal repeated results not only consistent with the classical approaches of hydrodynamics, but allow obtaining new data on the course of the processes under study.
