Zero Emission

This paper addresses the issue of incorporating rail transport into an urban delivery system. Its main purpose was to identify the possibilities of utilising rail transport in a Zero-emission Urban Delivery System (ZUDS) by applying Light Freight Railway (LFR) electric trains. The study applied the following research methods: literature review, observation, case study, and mathematical computations. In order to estimate the volume of transport external costs reduction resulting from shifting urban deliveries from road to rail transport in the city of Szczecin, the EU methodology was applied to specify the amounts of external costs generated by individual modes and means of transport. The research study showed that application of LFR electric trains makes it possible to significantly reduce external costs generated by transport. Moreover, this solution may have an impact on developing Clean Transport Zones (CTZs) and may also contribute to expansion of the ZUDS. The research study results also provide grounds to conclude that application of the LFR system makes it possible to reduce negative effects generated by Urban Freight Transport (UFT) and to achieve a coherent zero-emission system for handling cargo and passenger flows in cities, which consequently contributes to achieving electromobility goals in transport.

AbstractCity logistics has the goal of optimizing the entire logistics system within the city area and thus positively impact the quality of life. Different measures and initiatives, aimed at the optimisation of city logistics and reduction of the negative effects of urban freight transport are access zones or goods (freight) receiving points in the city centre, restrictions of vehicle dimensions, time schedule of delivery, consolidation strategies, use of urban distribution or consolidation centres, use of electric cars, use of urban public transport and mobility management. In the last couple of years, the city of Šibenik has experienced a tourism boom, which includes the organisation of numerous festivals in the old town core, an increase in the number of visitors, an increase in the number of catering and shopping facilities, private accommodation units, hotels and hostels. The increased number of tourists and commercial establishments also broaches the question of delivery of food and non-food products into the old part of the city, especially during the tourist season.

Urban freight transport is essential for supporting our society regarding providing the daily needs of consumers and local businesses. In addition, it allows for the movement of goods, is distributed within urban environments, provides thousands of jobs, and supports economic growth. However, a number of issues are associated with urban freight transport, including environmental impacts, road congestion, and land use of freight facilities that conflicts with residential land use. Electric freight vehicles create zero emissions and provide a sustainable delivery system in comparison with conventional freight vehicles. In this study, a novel dynamic inventory routing and pricing problem under a mixed fleet of electric and conventional vehicles was formulated to minimize the total travel and charging costs. The proposed model is capable of deciding on replenishment times and amounts and vehicle routes. We aimed to determine the maximum social welfare (SW) capable of providing an optimal trade-off between the supplier cost and customer delay that uses a mixed fleet of vehicles. Our computational study was conducted on real data generated from a delivery dataset in Tehran. Under the proposed policy with a fleet of only electric vehicles, the SW increased by 3% while the average customer delay reduced by 15% compared with a fleet of conventional vehicles. The results show that the number of served customers and customer delay would be affected by transitioning conventional urban freight vehicles to electric vehicles. Therefore, the proposed delivery system has a significant impact on energy savings and emissions.

The Given

This paper focuses on effects of implementing zero-emission buses in public transport fleets in urban areas in the context of electromobility assumptions. It fills the literature gap in the area of research on the impact of the energy mix of a given country on the issues raised in this article. The main purpose of this paper is to identify and analyse economic effects of implementing zero-emission buses in public transport in cities. The research area was the city of Szczecin, Poland. The research study was completed using the following research methods: literature review, document analysis (legal acts and internal documents), case study, ratio analysis, and comparative analysis of selected variants (investment variant and base variant). The conducted research study has shown that economic benefits resulting from implementing zero-emission buses in an urban transport fleet are limited by the current energy mix structure of the given country. An unfavourable energy mix may lead to increased emissions of SO2 and CO2 resulting from operation of this kind of vehicle. Therefore, achieving full effects in the field of electromobility in the given country depends on taking concurrent actions in order to diversify the power generation sources, and in particular on increasing the share of Renewable Energy Sources (RES).

The world-wide crisis caused by the Coronavirus disease 2019 (COVID-19) pandemic had a significant impact on the global economy functioning and the sustainable development of supply chains. The changes also affected seaports being the key links of maritime supply chains. The purpose of the research study described in this article was to identify the sources and kinds of disruptions observed in various maritime supply chains as a result of the COVID-19 pandemic and their impact on the operations of various types of seaport terminals, namely those serving bulk (universal, specialised) and general cargoes (universal, specialised). An additional purpose was to identify the dependencies between the type of terminal and its main function, and the tactical decisions adopted by the particular terminals. The research was carried out using the multiple-case study method. The study covered some selected port terminals functioning in Polish seaports (Gdańsk, Szczecin, Świnoujście), applying direct, semi-structured in-depth interviews. The analysis of the results was carried out using the inductive reasoning method. The research study has shown that as a result of the COVID-19 pandemic some maritime supply chains ceased to exist, some of them were operating with decreased cargo volumes, while in other cases the transshipment volumes actually rose during the pandemic. Among terminal operators’ tactical responses to disruptions in maritime supply chains, there were pro-active and adaptive measures. Pro-active (offensive) measures included actions taken by an enterprise in order to engage in new maritime supply chains, and even participating in establishing new maritime chains in response to limitations caused by the pandemic. Adaptive (defensive) measures covered actions taken by the port terminals as a consequence of changes in the existing maritime supply chains, caused by the pandemic in the port’s foreland or hinterland. The research study results revealed that the terminals extent of engagement and tactical decisions related to the pandemic were depended on the type of terminal (universal or specialised) and its main function played within a supply chain.

The Relationship

Purpose – The purpose of this paper is to evaluate privacy boundaries and explores employees’ reactions in employee monitoring. Design/methodology/approach – The research used the metaphor of boundary turbulence in the Communication Privacy Management (CPM) theory to demonstrate the psychological effect on employees. The model comprised organizational culture, CPM, trust, and employee performance in employee monitoring to further investigated the influence exerted by organizational culture and how employees viewed their trust within the organization when implementing employee monitoring. Variables were measured empirically by administrating questionnaires to full-time employees in organizations that currently practice employee monitoring. Findings – The findings showed that a control-oriented organizational culture raised communication privacy turbulence in CPM. The communication privacy turbulence in CPM mostly had negative effects on trust in employee monitoring policy, but not on trust in employee monitoring members. Both trust in employee monitoring policy and trust in employee monitoring members had positive effects on employee commitment and compliance to employee monitoring. Research limitations/implications – This research applied the CPM theory in workplace privacy to explore the relationship between employees’ privacy and trust. The results provide insights of why employees feel psychological resistance when they are forced to accept the practice of employee monitoring. In addition, this study explored the relationship between CPM and trust, and offer support and verification to prior studies. Practical implications – For practitioners, the findings help organizations to improve the performance of their employees and to design a more effective environment for employee monitoring. Originality/value – A research model was proposed to study the impacts of CPM on employee monitoring, after a broad survey on related researches. The validated model and its corresponding study results can be referenced by organization managers and decision makers to make favorable tactics for achieving their goals of implementing employee monitoring.

ABSTRACT Aflatoxin (AF) contamination of groundnut poses a serious health and economic threat to Benin market participants. However, most farmers are unaware of the problem. A study of 182 farmers was conducted in 2002 using a Health Belief Model (HBM) to examine Benin farmers’ health beliefs, perception constructs of awareness, susceptibility, seriousness of the problem, barriers, and benefits derived from reducing AF levels. Exploratory Factor Analysis was employed to evaluate the HBM model constructs. The average age of farmers was 40.4 years with a Standard Deviation (SD) of 10.8, and farmers had an average of 18.32 years of farming experience. Approximately 93% of farmers stated that sorting of groundnuts was important or very important, while 77% thought that they were sure or definitely sure of the negative effects of AF on human health. The exploratory factor analysis revealed that two factors embodied the susceptibility, barrier and benefit constructs. The study results indicated that the reduction of AF in groundnuts was multidimensional and required policy intervention to increase awareness of the health risks, and to manipulate the factors that influenced the constructs at the farm and policy level.
