Rising healthcare demands coupled with declining public funds necessitate increased efficiency in pharmaceutical procurement. Centralized Pharmaceutical Procurement (CPP) systems offer a solution by leveraging volume-based procurement, where a commission aggregates demand and negotiates lower prices, also improving access to affordable medicines for all. The Hub-and-Spoke (HaS) model emerges as a promising logistics solution, since it employs a central warehouse to streamline distribution and reduce transportation times. In scientific literature, a comprehensive study integrating this model with the entire CPP process is lacking. Therefore, this research aimed to investigate, through a systematic literature review, the aspects that characterise the application of the HaS model as an enabler of CPP policies. The analysis suggests the applicability of the HaS model for centralized pharmaceutical logistics. However, it emphasised the importance of long-term strategies and robust data management systems to guarantee the efficacy of these initiatives.

An evaluative project was undertaken at the University of Wolverhampton centring on the Hub and Spoke model utilised for organisation of placement allocation across the BNurs programme for all fields of nursing. Student experience was of particular interest throughout the evaluation with the research team focusing on the views, feelings and experiences of student nurses in relation to the hub and spoke model applied for practice. A qualitative approach was adopted, initially using Survey Monkey to collect student views through a series of open questions, and further enhanced by focus groups. These were transcribed and together with the data from the surveys, data was categorized and themed. Themes were analysed and conclusions drawn. The hub and spoke method for placements was found to enhance student understanding of the whole patient journey which offered students a wide breadth of experience and development of transferable skills such as communication and adaptability. A sense of increased belonging was highlighted by students which encouraged the development of strong effective relationships positively affecting their learning. Some less positive aspects were apparent revolving around personality difficulties and organisational problems, in particular relating to spoke placements. The purpose of spoke placements was not always apparent and sometimes there was a lack of appropriate student placement experiences provided by spoke mentors. Overall the hub and spoke model for organising placement was found to be beneficial and enhanced the student's experience, satisfaction and learning, which in turn had a positive effect on practice.

We develop two stage fixed-effects single-spill and double-spill models for congestion connection spills of London Heathrow and Frankfurt airports on 9 hub airports in Europe and the Gulf. Our panel data covers connection traffic from 1997 to 2013 for Heathrow and 1997 to 2011 for Frankfurt. The single-spill results support strongly that the connection spills from Heathrow's capacity limitations do strengthen competing hub airports of major alliance groups and to a lesser degree one Gulf hub. The double-spill model for Heathrow and Frankfurt shows nearly asymmetric overall spill characteristics between the two airports. Our results underline the influence of airline network strategies on congestion spills as European airline networks are shaped by alliances and umbrella mergers. Thus, the airline network perspective in airport capacity expansion decisions needs to play a greater role, as indicated by our asymmetric results for overall spill effects between Heathrow and Frankfurt airports.

Coronavirus disease 2019 emergency has created an enormous stress on providers that have been transformed into coronavirus disease hospitals. This article presents the experience of the clinical laboratory of Spedali Civili in Brescia (a teaching hospital in Lombardy with over 1500 beds) in managing the crisis, and to offer practical considerations for laboratory testing for this cohort of patients. Our contribution is threefold: by comparing the demand for tests in two representative period before and within the crisis, we show the change in compositions of the analytes that other labs may expect; we present the new panels of tests that hospital staff can order with different advantage for wards and laboratory; and we show how to reorganize staff on the basis of changes mentioned above.

Background The first Covid-19 epidemic outbreak has enormously impacted the delivery of clinical healthcare and hospital management practices in most of the hospitals around the world. In this context, it is important to assess whether the clinical management of non-Covid patients has not been compromised. Among non-Covid cases, patients with Acute Myocardial Infarction (AMI) and stroke need non-deferrable emergency care and are the natural candidates to be studied. Preliminary evidence suggests that the time from onset of symptoms to emergency department (ED) presentation has significantly increased in Covid-19 times as well as the 30-day mortality and in-hospital mortality. Methods We check, in a causal inference framework, the causal effect of the hospital's stress generated by Covid-19 pandemic on in-hospital mortality rates (primary end-point of the study) of AMI and stroke over several time-windows of 15-days around the implementation date of the State of Emergency restrictions for COVID-19 (March, 9 th 2020) using two quasi-experimental approaches, regression-discontinuity design (RDD) and difference-in-regressiondiscontinuity (DRD) designs. Data are drawn from Spedali Civili of Brescia, one of the most hit provinces in Italy by Covid-19 during March and May 2020. Findings Despite the potential adverse effects on expected mortality due to a longer time to hospitalization and staff extra-burden generated by the first wave of Covid-19, the AMI and stroke mortality rates are overall not statistically different during the first wave of Covid-19 than before the first peak. The obtained results provided by RDD models are robust also when we account for seasonality and unobserved factors with DRD models.

Researchers have written extensively on the impact that strategic alliances between airlines have on airfare, but little is known of the market entry deterrent impact of strategic alliances. Using a structural econometric model, this paper examines the market entry deterrent impact of codesharing, a form of strategic alliance, between incumbent carriers in domestic air travel markets. We find evidence of market entry deterrence, but deterrence impact depends on the specific type of codesharing between market incumbents as well as the identity of the potential entrant. We quantify the extent to which market incumbents' codesharing influences potential entrants market entry cost and probability of market entry.

By analysing the cwTen.t situation on the Croatian transportation market, and considering all parameters needed for the development of combined transport, measures are suggested in order to improve and stimulate its development. One of the first measures is the standardisation and introduction of unique tariffs for combined transport, and then government incentive for the organisation and development of combined transport means and equipment. A significant role in this should be set on adequately defined transport policy.

Does home market size matter for the pattern of trade? Krugman started the literature, showing it does matter. Davis overturned his result, arguing that an assumption of convenience-transport costs only for the differentiated goods-conveniently obtained the result. Here we relax another persistent assumption of conveniencetwo industry types differentiated only by the degree of scale economies-and find that market size reemerges as a relevant force in determining industrial structure.

Author(s): Ioannou, Petros; Giuliano, Genevieve; Dessouky, Maged; Chen, Pengfei; Dexter, Sue | Abstract: The current freight transportation network is highly unbalanced as routing decisions are made by individual users without coordination. Certain routes may become congested when chosen based on current traffic information without any anticipation that if other users do the same, these routes are no longer the best. This project developed a centrally coordinated load balancing system that considers all user demands and generates individual routes that balance freight loads across the network by minimizing cost. It is initially assumed that all vehicles are diesel and then gradually increases zero emissions vehicles such as electric trucks for a mixed fleet of trucks. The electric trucks add additional constraints due to limitation of range and charging time of batteries. As the number of electric trucks increases, the emissions reduce as expected; however, the cost of charging does...

In this research, the authors investigate firms' exit behaviors. On the basis of extant literature in economics, strategy, and marketing, the authors identify market- and firm-specific factors that influence exit behavior. They account for firms' uncertainty about a market's true attractiveness after entry on the probability of exiting a market. To evaluate exit decisions, they propose a Bayesian belief-updating model of learning embedded in a logit model that incorporates market- and firm-specific factors. The estimated evolution of beliefs over time enables the authors to determine whether firms use market information to update their prior beliefs about market attractiveness. The authors empirically investigate the market exits of new entrant discount airlines from city-pair markets. The results suggest that a combination of several market and firm factors influences exit behavior. Airlines' prior beliefs about market attractiveness are not necessarily consistent w...

Alianzas entre compañías aéreas: ¿ventajas permanentes? El objetivo en este trabajo es investigar los efectos de las alianzas entre empresas de transporte aéreo de pasajeros. Entre las ventajas se suelen mencionar: la posibilidad de destinar la mejor aeronave para cada segmento con economía de costos, la expansión de la red, la mayor oferta de servicios, el mayor número de pares origen-destino para un mismo total de pax.km volados. Dichas ventajas quedan claras en un análisis ceteris paribus. Las ventajas estimadas no se materializan según lo previsto, pues, aunque cada una de las empresas que forman parte de la alianza pase a volar en distancias mayores, llevando a un mayor número de pasajeros, ocurre una reducción de tarifas en virtud de factores relacionados con la industria, como la alta competencia en el sector, oriunda de la desregulación y de la llegada al mercado de empresas de bajo costo, lo que aporta a las empresas que forman parte de las alianzas sólo benefi cios modestos.

As millions of minutes are being exchanged between international telecom carriers on daily basis, transit and termination of international voice calls (or long distance calls) is considered among the main revenue generators for telecom carriers all over the world. The objective of international telecom carriers is to offer the best quality calls at the cheapest cost to sustain the highest profitability. This objective requires them to ensure a continuous optimization of the cost-quality combination. However, optimizing between the best (quality) and the cheapest (cost) is becoming a very complex task especially with the very dynamic nature of the international telecom market on the technical as well as the commercial levels. Considering the capacity of the interconnections between a carrier and its suppliers adds to the complexity of the problem as it forces the carrier to be selective in what traffic to pass and on which routes to send it in order to achieve the best outcome. In this paper we are proposing a decision support system to distribute the traffic on the available routes considering their capacity in view of the observed quality, profitability and forecasted traffic for the planning time period. The proposed model was found to be effective in solving the problem considering the decision maker's preferences.

A model of a transportation system is expected to be useful in simulations of a real system to solve given transportation tasks. A connection graph is routinely used to describe a transportation system. Vertices can be train stations, bus stops, airports etc. The edges show direct connections between vertices. A direct approach can be difficult and computational problems can arise in attempts to organize or optimize such a transportation system. Therefore, a method for aggregating such graphs was introduced, using a general kernel and shell structure and its particular instances: α-clique structured graphs of connections and a hub and spoke transformation of the source graph. These structures enable the concentration and ordering of transport between vertices and reduction of the analyzed graph. To obtain the desired structures, several versions of a specialized evolutionary algorithm were developed and applied.

The theory of transportation systems deals with models of phenomena connected with movement of goods and persons. The model of the transportation system should simulate a real system, but should also be a tool that enables to solve given transportation tasks. In order to describe transportation system (rail, bus or air), as a routine a connection graph would be used. Vertices of the graph can be train stations, bus stops or in case of air transport – airports. The edges of the graph show direct connections between vertices. It can be noticed that such a graph can have many vertices as well as many edges. Its direct application can be difficult and computational problems can occur while one would try to organize or optimize such a transportation system. Therefore, a method of aggregation of such a graph was introduced, using the hub-and-spoke structured graph of connections. This structure enables to concentrate and order the transport of goods/persons among vertices. To obtain the h...

The Centralized Carrier Collaboration and Multi-hub Location Problem (CCCMLP) represents a strategy that small-to-medium sized less-than-truckload (LTL) carrier companies can use in order to improve their profit margins. It is a strategy that is being explored in order to make these companies more sustainable as they are forced to reinvent their processes and supply chains. In this work, I will present a metaheuristic approach to optimizing their hub establishment and routing policies in order to better their expected profit margins and reduce their environmental impacts. The study considers the costs of transportation, loading and unloading, maintenance, operations, and inventory holding as part of the costs incurred by the carriers. Additionally, there is a cost incurred by the establishment of a hub for shipment consolidation. Similarly, there are environmental impacts to be considered. These are to be represented and accounted for in terms of the Global Warming Potential (GWP) they represent. Optimality in the results will be represented by a Pareto front, which will be compared with some single-objective solutions for reference. The objective of the CCCMLP is to seek a set of hybrid collaborative consolidation transshipment hubs with the purpose of establishing a collaborative hybrid hub-and-spoke network system to minimize the aforementioned parameters. The problem is modeled using Universal Generating Functions (UGFs) for the stochastic variables and solved using a Multi-Objective Evolutionary Algorithm (MOEA).

Purpose-Congestion at Ghana's main seaports is a problem that has received much attention recently. This is as a result of continuous increase in containerized cargo. To increase the capacity of Ghana' seaport, the Ministry of Transport through the Ghana Shippers Council initiated the Boankra Inland Port Project. The aim of this paper is to assess the feasibility and economic effects of implementing the Boankra Inland Port as a solution to reduce congestion at the main seaports, as well as reduce transportation cost. Design/methodology/approach-The location of the inland port was assessed using the gravitational model. Data for the gravitational model are distances from the main seaports in Ghana and Boankra Inland Port to major hinterland destinations and population of the destinations. Also, 210 respondents were selected and interviewed on contribution of the dry port concept to the economy and transportation management in Ghana. Findings-The results of the gravitational model support the location of Boankra as an inland port. A further comparison between Tema and Takoradi shows that Tema has a better location as a distribution center than Takoradi. Practical implications-Although Tema and Takoradi are the main seaports in Ghana, the implementation of the Boankra inland port will reduce the transportation cost for cargo with hinterland destinations, therefore making it a rational and cost-efficient location for transit transportation. Originality/value-This paper is among the first significant attempts to evaluate the suitability of inland port implementation in Ghana.

The value chain can be defined as a set of all processes and procedures necessary to deliver a product or service to the end-user through various stages of development. A concept of the value chain is essential in the context of transport, as the transport process is usually one of the last elements of the value chain and determines the final value of a product or service offered. In recent years, the domestic and international rail transport market has undergone significant changes, including ongoing globalisation processes, growing importance of international trade, increase in intermodal transport significance, numerous investment outlays in transport infrastructure, means of transport, and the area of rail transport interoperability. All the above-described aspects have an impact on the value chain in transport. This paper presents an analysis of the value chain in

Background: The commonest congenital musculoskeletal deformity worldwide is talipes equino varus (CTEV). Of the various treatment methods available, the most acceptable treatment currently for CTEV worldwide is serial manipulation and casting using the Ponseti technique. The Ponseti technique consists of weekly manipulation and casting for an average of six to eight weeks followed by bracing of the feet till school age. Some studies have shown evidence that more frequent casts may have similar outcomes with weekly casts using the Ponseti method. This study compared the efficacy of management of idiopathic CTEV using an accelerated protocol of twice weekly casts, with the standard weekly Ponseti protocol. Methods: The study was a randomized case control study with a group of patients undergoing an accelerated casting protocol involving twice weekly casts compared with another group who went through the normal weekly Ponseti protocol. Results: A total of 45 feet in 28 patients were studied. The study showed a significantly shorter treatment period in the accelerated protocol (39 days) compared with the standard protocol (52 days); with no significant increase in the number of casts needed for treatment. Conclusions: A twice weekly Ponseti casting protocol enables completion of the casting period earlier than the standard Ponseti method.

Choosing an optimal bunkering port that minimises the increase in the operating costs in a hub and spoke system is a multi-criteria decision-making (MCDM) problem. Furthermore, the criteria are related to the port particularities, the environment, fuel price, and some criteria are quantitative while others are qualitative. It is therefore necessary to create a model that takes such features into consideration. Firstly, in this paper a set of the most used criteria will be defined. Then, a method to choose suitable criteria for a hub and spoke system will be proposed. Secondly, using a Fuzzy AHP, weights will be defined and used in a multi-criteria goal function. The outcome is a bunkering policy MCDM model based on the aggregation of fuel consumption and price to criteria related to port characteristics, local aspects and service particularities. All these factors must be considered by a chief engineer (superintendent) in the process of defining a sustainable bunker policy. A case study based on the North Adriatic port system demonstrates the applicability of the proposed model. In addition, the case study highlights that in hub and spoke systems with short loops, feeder ships can regulate cargo capacity and stay at a port with bunkering policy planning.

Integration is the process of enabling a communication between disparate software components. Integration has been the burning issue for large enterprises in the last twenty years, due to the fact that 70% of the development and deployment budget is spent on integrating complex and heterogeneous back-end and front-end IT systems. The need to integrate existing applications is to support newer, faster, more accurate business processes and to provide meaningful, consistent management information. Historically, integration started with the introduction of point-to-point approaches evolving into simpler hub-and spoke topologies. These topologies were combined with custom remote procedure calls, distributed object technologies and message-oriented middleware (MOM), continued with enterprise application integration (EAI) and used an application server as a primary vehicle for integration. The current phase of the evolution is service-oriented architecture (SOA) combined with an enterprise...

This study aims to make a comparative evaluation of the change in the incidence of intracranial hemorrhage [intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH)] cases that attended our hospital in the Covid-19 pandemic period with that of the same term one year ago. This study included 80 patients diagnosed with ICH and/or SAH in the period that started with the pandemic in 2020. It was determined that 51 patients had been diagnosed with ICH and/or SAH during the same period of 2019. A total of 131 ICH and SAH patients (2019; n= 51, 39%; and 2020; n = 80, 61 %) having an average age of 64.52 ± 7.33 including 66 women (50.4 %) were included in the study in the nine-month follow-up periods covering the period of March-November of 2019 and 2020, respectively. It was determined that the number of patients diagnosed with ICH and SAH during the pandemic was higher than the number of those who attended our clinic in 2019 (80 vs 51) and that they were older (65.76 ± 6.56 years vs 62.57 ± 8.09 years) (p = 0.014 and p = 0.026, respectively). The incidence and distribution of ICH and SAH among the patients were similar (p > 0.05). It was determined that in 1 patient, ICH and SAH co-existed. In the study, it was determined that among the patients treated for intracranial hemorrhage in 2020, 32.5 % were diagnosed with COVID-19 as validated by positive nasopharyngeal SARS-CoV-2 PCR. The evaluation of the patients in 2020 revealed that the average age and ICH and SAH incidence in COVID-19 (+) and COVID-19 (-) patients were similar. Although increased incidence of acute intracranial hemorrhage has been observed during COVID-19 pandemic a athophysiological correlation between the two clinical presentations could not be clearly demonstrated. When rapidly progressing neurological deterioration fi ndings are present in COVID-19 patients, existence of intracranial hemorrhage should always be considered (Tab. 2, Ref.

To realize the airline service process, an airline has to have numbers of services in different level such as ground handling, passenger/cargo terminal service, airport navigation service, customs service, security service etc. Because of the concept of the service, producing and consuming take place at the same time. Therefore, airport capacity should be planned, monitored and managed in advance by assigning time, park position and boarding/unloading process. Airport capacity is detected with the assessment of construction of facilities and other factors affecting the capacity. This acquired capacity is allocated to the demanders according to specific conditions and privileges. In the first stage of this paper, the theoretical research of airport slot coordination system has been examined. In the second part, with the data acquired by study in practice airport coordination, slot, slot types, slot allocation and slot allocation types has been stated with tables. In the final part of the study, the categorization of slot allocation has been discussed and evaluated by employees working at both airport and airline business by means of semi-structured interview. With analyzing the obtained results, the slot coordination system used in Atatürk Airport has been identified and on the purpose of improvement of system some recommendations have been made.

The movement of large and heavy cargo for construction projects is part of tramp shipping, which is still considered a niche problem (Pache 2019). At the same time, containerisation has dominated international trading in intermodal transport, with 20' or 40' steel boxes transported with different modes of transport from vessels, trains, and trucks and handled in many other ports across the world throughout the end-to-end supply chain (Song 2021). The recent research was more focused towards containerisation and bulk shipping. Currently, the research in the shipping industry mainly concentrates on bulk and containerisation shipping. Not many academia study the logistics system for oversized or Out of Gauge (OoG) cargoes, which exceed the dimensions of 40ft High Cube containers size. The recent expansion of infrastructure development towards the modularisation and renewable energy sectors surges academic interest in the project logistics sector.

Develop a supply chain infrastructure is one of the most challenges faced by governments, trying to achieve an efficient logistic network. As an option to improve the congestion in seaports and reduction in transportation cost, dry ports have a key role to play in advancing port-hinterland connectivity. While many researches have been developed in Asian and European countries, studies about dry port are still in the early stage in Latin America. However, there are many issues to be discussed in these areas, with poor railways infrastructures, covered by bureaucratic customs processes in countries with economic and political instability, as happen in Brazil. To overcome the literature gap, this article presents a preliminary study about dry ports in northeast of Brazil, classifying the four logistic structures in that region and exploring, by two case studies, the main strategic issues related to Brazilian dry ports. This study provides a useful insight to policymakers, as well for d...

This work explores the perception of actors in multimodal transportation to arrive at the significant factors influencing the quality of multi-modal transportation for containers from the India. The existing literature focuses on a particular issue, or some issues, such as cost, time or infrastructure related to logistics or concerns of a firm in maintaining efficacy of logistics operations. In this research, an attempt has been made to compile and analyse the major relevant issues and challenges of the primary stakeholders associated with multimodal transportations. The responses of the stakeholders, represented by the managers of the firms, in the logistics chain have been obtained through semi-structured interviews. The responses have been analysed qualitatively, and the summary of the results have been vetted by the respondents. The customers' perspectives have been further obtained by analysing their comments on the social networking websites of logistics firms. These e-comments have been analysed using SentiStrength, data mining software. The results of the analyses reveal the factors affecting the perception of stakeholders about the quality of multimodal transportation.

OBJECTIVES During the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) pandemic, Northern Italy had to completely reorganize its hospital activity. In Lombardy, the hub-and-spoke system was introduced to guarantee emergency and urgent cardiovascular surgery, whereas most hospitals were dedicated to patients with coronavirus disease 2019 (COVID-19). The aim of this study was to analyse the results of the hub-and-spoke organization system. METHODS Centro Cardiologico Monzino (Monzino) became one of the four hubs for cardiovascular surgery, with a total of eight spokes. SARS-CoV-2 screening became mandatory for all patients. New flow charts were designed to allow separated pathways based on infection status. A reorganization of spaces guaranteed COVID-19-free and COVID-19-dedicated areas. Patients were also classified into groups according to their pathological and clinical status: emergency, urgent and non-deferrable (ND). RESULTS A total of 70 patients were referred to th...

Nowadays, the success of a maritime port does not depend anymore on its traditional intrinsic points of strength, such as the internal capacity, but also on its ability to effectively integrate the development of its hinterland into business relations and supply chains. Mediterranean ports can get competitive, if specific "regionalization" processes are launched and supported. Key point for this strategy is the hinterland involvement: logistics and transports integration, railways, realization and development of dryports, terminals, distribution centres. All these are core elements for this purpose. The overall focus has changed from port performances to performance of the entire supply chain in the port-hinterland relationship. This is what it is going to do the Port of Civitavecchia, the most important port in Lazio Region, would like to become the central point into commercial, industrial and infrastructural development of central Italy. The development of railway terminal and of regional road network for the developing of intermodal logistics chain, of the industrial port activities (shipbuilding sector and oil bunkering), of trade relations with Fiumicino Airport and with the roman agroindustrial sector, of logistics relations with the dryport of Orte and with the intermodal terminal (road-railway) of Pomezia Santa Palomba, are some of the activities planned and undertaken by the port for improving the regionalization of Civitavecchia. Aim of this paper is to show and underline how these regionalization processes can increase the development, and so benefit the entire regional hinterland and the competitiveness and attraction of the entire port system. A model to estimate the regionalization effect has been designed by the authors and implemented to make a comparison analysis between Civitavecchia and competing ports.
