Post-implementation challenges of ERP system in pharmaceutical companies

PurposeMany organizations failed to generate profits after investing considerable money and time in Enterprise Resource Planning (ERP) systems. This study, therefore, sought to identify the challenges encountered by pharmaceutical firms during the post-implementation of ERP systems.Design/methodology/approachA case-based study followed by general survey-based research was carried out in pharmaceutical firms to determine the critical post-implementation challenges of ERP systems. DANP (DEMATEL-based ANP) and Wilcoxon Signed Rank test were used to find the causal/critical challenges and rank them.FindingsAfter analyzing a pharmaceutical case company and conducting a general survey among pharmaceutical companies, statistical analysis was performed to identify the most significant challenges, namely, “Inefficient troubleshooting mechanism”, “Lack of training during post-implementation stage” and “Difficulty in identifying invalid data when entered into the ERP system”. Furthermore, organization-wide challenges are considered to be the most important.Practical implicationsThe paper identifies the challenges faced during the post-implementation phase of ERP systems. This work brings out the issues with ERP systems' performance after their implementation, which is related to the quality of the ERP systems. This work will support the risk identification and mitigation during ERP implementation to eradicate the problems after its implementation. This work may trigger the ERP system developers to improve its features and performance for better manufacturing and supply chain management system in pharmaceutical firms.Originality/valueThis study is uniquely conducted in pharmaceutical firms to study the benefits and challenges of adopted ERP systems. A pilot case study served as the foundation for the generalizability of other pharmaceutical firms' findings through a non-parametric test.

Science as a game: conceptual model and application in scientific software design

ABSTRACT Scientific inquiry is often described as, and compared to, a game. This paper expands on that analogy to propose a conceptual model of scientific practice built upon Jesper Juul’s game definition, and informed by parallels between the two activities collected from selected works from history and philosophy of science. Moreover, the paper presents a design method, based on the model described, for fostering creative solutions in scientific software user interface design. Results from pilot case studies suggest both model and method are helpful, allowing participants to describe requirements and ideate solutions, as well providing a framework for the exploration of the game-science analogy within the context of scientific research conducted through computational resources.

Character Education to Improve Students’ Sense of Relatedness: Preliminary Findings from the Positivity Project

Sense of relatedness is a key component of students’ social-emotional learning, as it captures the degree to which students’ feel they have quality relationships with others in school. The purpose of the current pilot case study is to measure students’ sense of relatedness and assess the degree to which a new character education social-emotional learning program based in positive psychology – The Positivity Project (P2) – is having a positive impact on students. Results from the two case studies including 108 elementary school students and 154 middle school students indicate positive associations between P2 implementation and increases in self-reported sense of relatedness.

Urban Acupuncture as a Method of Open Space Regeneration in Greek Ex-Refugee Areas. The Case of Nikea, Piraeus

The paper explores the potential of implementing the principles of urban acupuncture in a selected Greek case study, taking into account international experience in the field. The research includes literature review and field work. The area of study is Nikea, an ex-refugee urban area in the Attica metropolitan region. It was founded during the 1930s to host refugees from Asia Minor. The initial Hippodamian grid offers beneficial intermediate communal spaces inside each city block and there are also larger green spaces in proximity. However, the area suffers from urban blight owed largely to the poor quality of preservation of the old refugee housing estates. A mixture of factors contributes to the complex contemporary situation characterized by opportunities and challenges. On the one hand, there is great potential for regenerating the existing intermediate communal spaces and on the other decaying refugee houses and vulnerable households intricate the already convoluted situation. The paper provides cartographic depiction and categorization of the existing open spaces highlighting also contemporary socio-spatial challenges and market driven limitations. The research describes the obstacles that hinder the activation of “urban sensitive points” in terms of urban acupuncture, also advocating for possible solutions. The paper opens dialogue on the Greek case study in terms of urban acupuncture with the view to suggest strategies to foster socio-spatial cohesion in degraded ex -refugee urban areas. This is a pilot case study with further application in other post-refugee urban areas in Greece that share common socio-spatial attributes. Thus, the topic of the paper may have a greater impact within the Greek urban context.

Precision environmental health monitoring by longitudinal exposome and multi-omics profiling.

Conventional environmental health studies have primarily focused on limited environmental stressors at the population level, which lacks the power to dissect the complexity and heterogeneity of individualized environmental exposures. Here, as a pilot case study, we integrated deep-profiled longitudinal personal exposome and internal multi-omics to systematically investigate how the exposome shapes a single individual's phenome. We annotated thousands of chemical and biological components in the personal exposome cloud and found they were significantly correlated with thousands of internal biomolecules, which was further cross-validated using corresponding clinical data. Our results showed that agrochemicals and fungi predominated in the highly diverse and dynamic personal exposome, and the biomolecules and pathways related to the individual's immune system, kidney, and liver were highly associated with the personal external exposome. Overall, this data-driven longitudinal monitoring study shows the potential dynamic interactions between the personal exposome and internal multi-omics, as well as the impact of the exposome on precision health by producing abundant testable hypotheses.

Abstract B024: Exploring the temporal dynamics of pancreatic cancer through post-mortem tumor analysis: A pilot case study

Abstract Introduction Pancreatic cancer is a lethal disease with an incidence little higher than the mortality rate. Great advances in oncology have been made in recent years with new treatment strategies for many cancers, leading to substantial improvement in patient outcome. The prognosis for pancreatic cancer patients, however, remains dismal and chemotherapy is still standard of care. An increased understanding of the temporal evolution and resistance mechanisms of pancreatic cancer during chemotherapy is necessary to improve patient outcome. To this end, the Chemotherapy, Host response And Molecular dynamics in Periampullary cancer study (CHAMP) was initiated in 2018. It is an ongoing, prospective observational trial in which blood samples are taken from patients at each chemotherapy cycle. Recently, the CHAMP- Extended Tissue Analysis (ETA) study was initiated, wherein selected patients enrolled in the CHAMP-study undergo targeted autopsies. The aim of this study was to compare the expression of selected immunohistochemical (IHC) markers and the quality of DNA in tumor tissue from an ante-mortem resected metastasis to the ileum and post-mortem collected tumor tissue in the first patient enrolled in the CHAMP-ETA study. Methods The autopsy was performed by a senior pathologist in accordance with standard procedure guidelines and all visible tumor was collected for analysis. The post-mortem interval (PMI) was 44 hours. Multiple tissue cores from formalin-fixed paraffin-embedded tumor tissue from the surgical resection and different tumor sites from the autopsy were assembled into a single tissue microarray (TMA) block. DNA was extracted from adjacent tissue cores obtained in parallel with the TMA-construction, and the quality examined by qPCR. IHC staining of standard diagnostic markers CK7, CK20, CDX2 and the proliferation marker Ki67 was performed on the TMA. Results In line with the expected, both normal and tumor tissue in the pancreas displayed a higher degree of autolysis compared to the metastases. Tumor areas surrounded by a more dense stroma tended to be less autolytic. CK20 and CDX2 expression was negative in all samples, both ante-mortem and post-mortem. CK7 was highly expressed in all tumor samples with an ever-stronger intensity in the post-mortem samples. Of note, CK7 was also strongly expressed in the tumor stroma of the post-mortem samples, but not in the pre-mortem samples. Ki67 expression was significantly higher in ante-mortem than in post-mortem samples. The extracted DNA was of sufficient quality in all tested post-mortem samples. Conclusion The results demonstrate that the DNA quality is sufficient after a PMI of 44 hours. The conditions for IHC staining are less optimal but may be sufficient for some markers. Access to post-treatment tumor tissue is an important complement to on-treatment biomarker studies, and of vital importance to understand the molecular events leading to terminal disease.

LIFE-CLIVUT, ecosystem benefits of urban green areas: a pilot case study in Perugia (Italy)

Trees have a great value in terms of ecosystem services in urban areas. LIFE CLIVUT is an “Information and Governance” European project developed in 4 Mediterranean Cities, with the goal of increasing the knowledge and awareness of citizens, especially young people, on the importance of the presence and good management of urban trees to mitigate the “Heat Island” effects. The data collected on the value of tree heritage and their future potential are used to design a green asset management strategy that will help urban planners adopt better practices for the mitigation of the effects of climate change in urban environments. This paper illustrates the results of tree census activity in four urban green areas of Perugia, Central Italy, that will be compared with those recorded in others cities involved in the project. Dendrometric parameters (diameter at breast height, tree height, first branch height, max and min crown width, crown shape and density) were recorded in situ using a dedicated software operating through a web app (“Clivut-Treedb”). The following ecosystem services were estimated: CO2 sequestration, particulate matter (PM) absorption, shadow effect, biodiversity indexes. Several tree species characterized by important wood structures during their adult phase, such as Pinus pinea, Quercus ilex, Q. pubescens, Ulmus carpinifolia, Populus alba and Aesculus hippocastanum showed the highest estimates of CO2 stored. Q. ilex was the most efficient species in particulate adsorption, showing similar estimates (about 60 g PM10 tree-1 year-1) in the 3 oldest green areas established in the 1980s, while the youngest plantations (dating back to 2005) absorbed about 10 g tree-1 of PM10 per year. In terms of the potential cooling effect of trees, preliminary estimates of the shaded areas highlighted the difference between the older green areas (about 50% of shading) compared to the younger ones (about 15% and 8%).

Internal Relational Illustration: A Pilot Clinical Case Study

The history of marriage and family therapy includes various ways to map families. This pilot case study aimed to fill the gaps in research concerning the use of maps in therapy while also introducing a new concept in Internal Family Systems (IFS) of a structured formalized way to create maps with clients. Using a qualitative method, the researcher presented therapy sessions with one established IFS client using the Internal Relational Illustration (IRI) method. The goal of this case study was to show the effectiveness of IRI in clinical work.

Assessing the quality of evidence in studies estimating prevalence of exposure to occupational risk factors: The QoE-SPEO approach applied in the systematic reviews from the WHO/ILO Joint Estimates of the Work-related burden of disease and Injury.

The World Health Organization (WHO) and the International Labour Organization (ILO) have produced the WHO/ILO Joint Estimates of the Work-related Burden of Disease and Injury (WHO/ILO Joint Estimates). For these, systematic reviews of studies estimating the prevalence of exposure to selected occupational risk factors have been conducted to provide input data for estimations of the number of exposed workers. A critical part of systematic review methodology is to assess the quality of evidence across studies. In this article, we present the approach applied in these WHO/ILO systematic reviews for performing such assessments on studies of prevalence of exposure. It is called the Quality of Evidence in Studies estimating Prevalence of Exposure to Occupational risk factors (QoE-SPEO) approach. We describe QoE-SPEO's development to date, demonstrate its feasibility reporting results from pilot testing and case studies, note its strengths and limitations, and suggest how QoE-SPEO should be tested and developed further. Following a comprehensive literature review, and using expert opinion, selected existing quality of evidence assessment approaches used in environmental and occupational health were reviewed and analysed for their relevance to prevalence studies. Relevant steps and components from the existing approaches were adopted or adapted for QoE-SPEO. New steps and components were developed. We elicited feedback from other systematic review methodologists and exposure scientists and reached consensus on the QoE-SPEO approach. Ten individual experts pilot-tested QoE-SPEO. To assess inter-rater agreement, we counted ratings of expected (actual and non-spurious) heterogeneity and quality of evidence and calculated a raw measure of agreement (Pi) between individual raters and rater teams for the downgrade domains. Pi ranged between 0.00 (no two pilot testers selected the same rating) and 1.00 (all pilot testers selected the same rating). Case studies were conducted of experiences of QoE-SPEO's use in two WHO/ILO systematic reviews. We found no existing quality of evidence assessment approach for occupational exposure prevalence studies. We identified three relevant, existing approaches for environmental and occupational health studies of the effect of exposures. Assessments using QoE-SPEO comprise three steps: (1) judge the level of expected heterogeneity (defined as non-spurious variability that can be expected in exposure prevalence, within or between individual persons, because exposure may change over space and/or time), (2) assess downgrade domains, and (3) reach a final rating on the quality of evidence. Assessments are conducted using the same five downgrade domains as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach: (a) risk of bias, (b) indirectness, (c) inconsistency, (d) imprecision, and (e) publication bias. For downgrade domains (c) and (d), the assessment varies depending on the level of expected heterogeneity. There are no upgrade domains. The QoE-SPEO's ratings are "very low", "low", "moderate", and "high". To arrive at a final decision on the overall quality of evidence, the assessor starts at "high" quality of evidence and for each domain downgrades by one or two levels for serious concerns or very serious concerns, respectively. In pilot tests, there was reasonable agreement in ratings for expected heterogeneity; 70% of raters selected the same rating. Inter-rater agreement ranged considerably between downgrade domains, both for individual rater pairs (range Pi: 0.36-1.00) and rater teams (0.20-1.00). Sparse data prevented rigorous assessment of inter-rater agreement in quality of evidence ratings. We present QoE-SPEO as an approach for assessing quality of evidence in prevalence studies of exposure to occupational risk factors. It has been developed to its current version (as presented here), has undergone pilot testing, and was applied in the systematic reviews for the WHO/ILO Joint Estimates. While the approach requires further testing and development, it makes steps towards filling an identified gap, and progress made so far can be used to inform future work in this area.

Influence of Loading Distance, Loading Angle and Log Orientation on Time Consumption of Forwarder Loading Cycles: A Pilot Case Study

Fully mechanized timber harvesting systems are well established in forest operations worldwide. In cut-to-length (CTL) systems, forwarders are used for extracting logs from the stand. The productivity of a forwarder is related to site- and stand-specific characteristics, technical parameters, organizational aspects, and the individual skills of the operator. The operator’s performance during “loading” considerably affects forwarder productivity, since this element occupies nearly 50% of forwarding cycle time in CTL operations. When positioning the forwarder for loading, different loading angles and loading distances arise. Additionally, different log orientation angles in relation to the machine operating trail can be observed. Therefore, an in-depth analysis of loading conditions was conducted. The goal of this pilot case study was to explore the potential impact of different loading angles and distances, and log orientation angles, on time consumption per loading cycle in order to derive indications for more efficient work practices. Therefore, controlled loading sequences were tested on a physical Rottne-F10-based forwarder simulator with an experienced forest machine operator. Three loading angles (45°, 90° and 135° azimuthal to the machine axis) with five loading distances (3, 4, 5, 6 and 7 m), and three log orientation angles (45°, 90°, 135°), resulted in a total of 45 settings, which were tested in 10 repetitions each. The time required for a loading cycle was captured in a time study, applying the snap-back method. Results showed that all three tested variables had a significant influence on time consumption per loading cycle. Loading at an angle of 135°, and from a close (3 m) or far distance (7 m) led to especially increased cycle times. Loading from 4 to 6 m distance could be detected as an optimal loading range. Additionally, log orientation angles of 45° and 90° led to increased loading efficiency. Even if the validity of the results may be limited due to different conditions and influencing factors in field forwarding operations, these data can contribute to a better understanding of the loading element and, in particular, to productivity determining factors of forwarder work.

Trauma of Peripheral Innervation Impairs Content of Epidermal Langerhans Cells.

Langerhans cells represent the first immune cells that sense the entry of external molecules and microorganisms at the epithelial level in the skin. In this pilot case-study, we evaluated Langerhans cells density and progression of epidermal atrophy in permanent spinal cord injury (SCI) patients suffering with either lower motor neuron lesions (LMNSCI) or upper motor neuron lesions (UMNSCI), both submitted to surface electrical stimulation. Skin biopsies harvested from both legs were analyzed before and after 2 years of home-based Functional Electrical Stimulation for denervated degenerating muscles (DDM) delivered at home (h-bFES) by large anatomically shaped surface electrodes placed on the skin of the anterior thigh in the cases of LMNSCI patients or by neuromuscular electrical stimulation (NMES) for innervated muscles in the cases of UMNSCI persons. Using quantitative histology, we analyzed epidermal thickness and flattening and content of Langerhans cells. Linear regression analyses show that epidermal atrophy worsens with increasing years of LMNSCI and that 2 years of skin electrostimulation reverses skin changes, producing a significant recovery of epidermis thickness, but not changes in Langerhans cells density. In UMNSCI, we did not observe any statistically significant changes of the epidermis and of its content of Langerhans cells, but while the epidermal thickness is similar to that of first year-LMNSCI, the content of Langerhans cells is almost twice, suggesting that the LMNSCI induces an early decrease of immunoprotection that lasts at least 10 years. All together, these are original clinically relevant results suggesting a possible immuno-repression in epidermis of the permanently denervated patients.

Potential of Accelerometers and GPS Tracking to Remotely Detect Perennial Ryegrass Staggers in Sheep

Perennial ryegrass staggers (staggers) is a neurotoxic condition in livestock that is caused by consumption of ryegrass (Lolium perenne) infected with specific strains of Epichloë fungal endophytes. These grass-endophyte associations produce toxins that can adversely affect animals and can in some cases lead to death. In sheep, symptoms typically include head shaking, changes in gait, stiffness and falling. Affected sheep can recover after removing them from pastures containing toxic strains of endophyte. A pilot case study was conducted in Lincoln, New Zealand to determine if ryegrass staggers could be identified with data collected through GPS tracking and accelerometers. Fourteen sheep per treatment grazed in either a toxic endophyte-infected ryegrass paddock or an endophyte-free control paddock for 17 days in late March and early April 2017. Randomly selected sheep were fitted with collars containing a 3-axis accelerometer recording movements at 12 Hz (10 collars in endophyte infected paddock and 6 in the control paddock). Three sheep per treatment were also tracked at 3-minute intervals with GPS receivers. Sheep were scored by an experienced observer for symptoms of staggers weekly and at the end of the study using a 0 to 5 scale. Control sheep did not display any symptoms of staggers and 10 sheep in the infected pasture displayed little or no symptoms (0 or 1 score). The other 4 sheep in infected pasture had scores from 2 to 4 at the end of the study. Sheep grazing in the infected pasture (2.91 m/min ± 0.04 SE) moved slower (P=0.04) than sheep in the control pasture (3.12 m/min ± 0.05 SE). Distance travelled varied among days, but there did not appear to be any temporal trends. Machine learning analyses of accelerometer data showed that the behavior of affected sheep changed during the study. Activity of sheep displaying symptoms (scores ≥ 2) increased more in the morning and midday during the latter part of the study than control sheep and sheep with few or no symptoms (score < 2). However, behavior of individual sheep at night remained relatively consistent during the study. Accelerometers may be useful for remotely detecting perennial ryegrass staggers.

Social Isolation and the Use of Technology in Caregiving Dyads Living With Dementia During COVID-19 Restrictions.

BackgroundPeople with dementia (PwD) and their informal caregivers (caregiving dyads) face multiple impacts of the COVID-19 pandemic, including restricted social support services and social isolation. With limited opportunities for caregiving dyads to participate in social activities during the pandemic, the potential of social technology to support social participation and dyadic relationships should be explored. As a part of an ongoing feasibility trial, this study assesses how COVID-19 has impacted community-dwelling dyads in a dementia caregiving context. The dyads' use of social technology and their motivations to invite technology into social interactions are explored.MethodsA pilot case study employing baseline interview data from three community-dwelling caregiving dyads. Each dyad consisted of a husband with a dementia diagnosis and his wife, who performed most caregiving tasks. Interviews were audio-recorded, transcribed verbatim, and subjected to inductive thematic analysis. Two researchers independently coded the data, and collated the codes and themes collaboratively.ResultsTwo themes and seven subthemes were identified: (i) living with dementia during COVID-19 (subthemes: social and leisure activities, dyadic interactions, adjusting as caregiver); and (ii) the role of technology in a pandemic (subthemes: facilitating social activities, facilitating dementia care-related activities, barriers and facilitators to using social technology, the underlying motivation to invite technology into interactions). Dyads who were socially active pre-COVID-19, and who managed to make good use of technology to facilitate and maintain their social engagement during COVID-19, reported to have been less negatively impacted by COVID-related social restrictions.ConclusionThe dyads differed in how COVID-19 restrictions impacted their lives and how they coped with dementia, revealing different motivations for wanting to invite technology into their social interactions. During and beyond this pandemic, social technology can be a valuable tool for promoting social participation in this population, especially when in-person social contact is restricted. Successful uptake of social technology is dependent on customizing it to the individual's needs and conditions. Therefore, efforts are needed to tackle barriers that exist for older adults in using such technology.

Proposal of a multidimensional risk assessment methodolgy to assess ageing workforce in a manufacturing industry: A pilot case study

The demographic characteristics of the population are changing around the world. Although, the population ageing is a fairly slow and predictable phenomenon even today in the productive sectors there are no clear and shared strategies to take appropriate measures to reduce its impact on work. In fact, on one side the more “mature” workers represent a resource for their companies for their human and cultural heritage. But, on the other side, the ageing workers also have, in general, a lower adaptability to innovation, a lack of familiarity with information technology, less creativity, a relative loss of physical strength. In this scenario, many company are investigating how ageing workforce can impacts both operational and occupational safety and health (OSH) performance. Thus, the current debate is for the most part being focused on the safety and productivity implications of an ageing workforce. In this study, we first identified the aspects of safety, risks and operational affected by the ageing workforce (AW). The analysis showed that there is still little research dealing with the ageing of the workforce and how to evaluate risk in the workplace. Based on this, we then presented a multidimensional management approach for measuring performance within the ageing workforce in occupational safety contexts. The model wants to be an useful tool for policy and industrial decision-makers.

Analysis of Sustainable Transport Systems in Service of Selected SEA-EU Consortium Countries' Airports-A Pilot Case Study of Passenger Choices for Gdańsk Airport.

The article presents the results of a pilot study, namely a passenger survey on travel choices regarding commuting to the airport in one chosen location (Gdańsk, Poland). The study aimed at establishing which factors which influenced their travel time, assessment of travel time, choosing more or less sustainable transport mode, and also single-mode or multimodal travel. Research results show that choice of the means of transport influences travel time, that the highest travel times are generated by bus and car travel and that assessing the travel time as acceptable or not depends on travel time. However, the longer the travel time, the more likely was the passenger to accept it. What is more, it appeared that a few factors influence choosing a more sustainable transport mode: the purpose of the trip, the start of the trip to the airport, place of living, and job situation.

Exploring how international social workers perceive culturally relevant practices: A case study of Japanese social workers’ experiences in other Asian countries

AbstractThis pilot case study, as part of an international social work research project, explored how culturally relevant collaborative practices were perceived by international social workers. Semi‐structured interviews were conducted with social workers (n = 4) who had worked as Japan Overseas Cooperation Volunteers for 2 years in another Asian country. Thematic analysis was applied to their narratives. Three main themes were found: ‘socio‐cultural understanding based on local life and activities’, ‘collaborative practice with local stakeholders’ and ‘attitudes and perspectives at the local practice’. Although the background and context of the interviewees’ activities differed, they stressed the importance of deepening their socio‐cultural understanding, together with learning local languages and deploying appropriate communication methods, through living in each locality and interacting with local people. They also described the process of exploring the collaborative activities through dialogue with local people, while taking a reflective view. These findings indicate the necessity for a deeper examination of collaborative practice by domestic and international social workers in various fields.

Any questions? Young children questioning in their early childhood education settings

ABSTRACT Young children’s questions may offer powerful leverage for knowledge acquisition and deep level learning, yet often go unrecognised and undervalued in early childhood education (ECE) settings. When young children’s questions are not heard or respected, they are denied their UNCRC Article 12 right to express their views freely and have ‘due weight’ accorded to them. A pilot case study framed by critical pedagogy and young children’s rights perspectives was conducted in the Midlands region of England to investigate the nature and extent of young children’s questioning in ECE settings and its relationship with knowledge acquisition and learning. Early childhood students recorded questions young children (n = 9) (2.2–4.5 years) asked in ECE settings. Four categories of young children’s questions emerged, two oriented to knowledge acquisition and learning. Evidence also revealed effects of performativity impeding knowledge acquisition and learning by both adults and young children in ECE settings. Further study is indicated.
