Die Entfesselung des Project Management Office?
Authors: Braun Timo , Gerstle Joana , Lächelt Vincent
Published: September 2024

Project Management Offices (PMOs) haben sich im Laufe der Zeit kontinuierlich weiterentwickelt und professionalisiert. Trotz dieser Fortschritte müssen sie ihren Mehrwert für das operative Projektgeschäft und die gesamte Organisation ständig unter Beweis stellen und einen strategischen Beitrag aufzeigen. In der Praxis existiert eine große Vielfalt an PMOs mit unterschiedlichen Ausgestaltungen und Schwerpunkten, die jedoch meist innerhalb der Grenzen der eigenen Organisation agieren. Um PMOs zukunftsfähig zu machen und gleichzeitig eine neue Perspektive zu eröffnen, um die eigene Legitimation zu sichern, könnte eine Lösung darin bestehen, die Kompetenzbereiche so zu erweitern, dass ein überbetriebliches bzw. organisationsübergreifendes Agieren ermöglicht wird. Der vorliegende Beitrag basiert auf einer jüngst im Project Management Journal erschienenen Veröffentlichung [1] und stellt die daraus ableitbaren Konsequenzen für die Projektmanagementpraxis in den Mittelpunkt. Entsprechend werden die nötigen Schritte für ein „entfesseltes PMO“ aufgezeigt und erörtert, inwiefern eine schrittweise Heranführung einem überstürzten Handeln vorzuziehen ist, und dass je nach Kontext ein anderer PMO-Typ geeignet sein kann. Auch die Aufgaben für ein „entfesseltes PMO“ werden skizziert rund um das Selektieren, Regulieren, Allozieren und Evaluieren. Zum Ende des Beitrags wird kritisch beleuchtet, wie realistisch ein „entfesseltes PMO“ in der Praxis tatsächlich ist und wie wir uns diesem Typ weiter nähern könnten.

In the context of Industry 4.0, the development of cities worldwide has shifted from large-scale industrialization towards intelligent and sustainable growth. Contemporary urban researchers classify urban systems into three categories: hard cities, soft cities, and resilient cities. Hard cities refer to the physical framework and infrastructure of urban spaces, while soft cities embrace the art ,cultural, civilized, aesthetic, and humanistic aspects of urban life. Resilient cities, on the other hand, embody the plasticity necessary for sustainable development. This paper will utilize case study methodology and comparative research to analyze the positive effects and catalytic impact of the development of soft urban systems on hard cities and resilient cities.

Even with the development and progress of science and technology, peace has always been a topic to be explored, and many design competitions about peace had appeared, with people showing what harmony was and the beautiful vision of peace from different perspectives. This paper attempts to analyse from a semiotic point of view what elements of peace symbols the creator’s creations were made up of, the reason being that the selection of symbols and the application of the symbolic elements were an indispensable presence in the creation of posters and are utilised for communicating the subject. Therefore, this study adopts a unique children’s perspective to explore the direct or indirect relationship between symbolic elements and colour through the software to quantify the selection of poster samples systematically and ultimately to summarise and collate to explore the relationship between colour and semiotics of the analysed posters, hoping that this research can be more effectively used in the subsequent creation of the posters or symbols and colours to assist and help the role of the poster.

Authors: Asgari Behrooz , Majumdar Sudipa , Amoah Cosmos
Published: September 2024

This study evaluated the efficiency and productivity of the manufacturing industries of Singapore. Singapore is one of the world’s most competitive countries and manufacturing giants. All 21 manufacturing industries as classified by Singapore’s Department of Statistics were included in the study as decision-making units (DMUs). Using the Malmquist DEA on data spanning 2015–2021, we found that excerpt for the Paper and Paper product industry, all industries recorded positive total factor productivity (TFP). TFP ranged from 0.977 to 1.481. In terms of technical efficiency, 14 out of 21 industries showed positive efficiency change. The highest TFP was recorded in 2020 and the lowest in 2016. By measuring and improving efficiency, industries in Singapore can achieve cost savings, increase output, and enhance their competitiveness in the global marketplace. In addition, efficiency measurement can help policymakers identify potential areas for improvement and develop targeted policies to promote sustainable economic growth. Given these benefits, performance measurement is inevitable for industries and policymakers in Singapore to achieve economic objectives. Manufacturing industries need to find ways to manage the size and scale of operations as we flag this as an area for improvement.

Authors: Adrogué Cecilia , García de Fanelli Ana , Orlicki Eugenia
Published: September 2024

En este trabajo analizamos los factores que inciden en la configuración de las expectativas en los estudiantes secundarios respecto de continuar estudios universitarios. Utilizamos como fuente de datos el dispositivo nacional de evaluación “Aprender” aplicado en 2019 al alumnado del último año de la escuela secundaria argentina. Tras estimar modelos de regresión logísticos, los resultados muestran que a menor nivel socioeconómico del hogar del estudiante, mayor es la probabilidad de que elija realizar estudios terciarios en lugar de universitarios, o que decida combinar estudio y trabajo o trabajar únicamente o que no esté decidido. Además, las chances de tener expectativas de estudios universitarios son más altas para las mujeres, los no repitentes, aquellos que asisten a escuelas privadas, con progenitores de mayor nivel educativo y con mejor desempeño académico. Estos resultados son relevantes para el diseño de políticas que busquen disminuir la desigualdad social en el acceso a la universidad.
Exploring pathogenesis, prevalence, and genetic associations in Chiari malformation type 1: a contemporary perspective
Authors: Mohd Rosdi Siti Nornazihah , Omar Suzuanhafizan , Mohamad Ghazali Mazira , Ghani Ab Rahman Izaini , Mohamed Yusoff Abdul Aziz
Published: September 2024

Chiari malformation type 1 (CM 1) entails a structural defect in the cerebellum, involving the herniation of cerebellar tonsils toward the foramen magnum. The symptomatic or asymptomatic nature of CM 1 is contingent upon the condition of malformation in the spinal cord. This review presents an updated perspective on the prevalence of CM 1, its pathogenesis, genetic associations, and treatment. CM 1 exhibits a higher prevalence in adult females than males. Despite the incomplete understanding of the exact cause of CM 1, recent research suggests the involvement of both genetic and environmental factors in its development. One of the reasons for the occurrence of CM 1 in individuals is the smaller posterior cranial fossa, which manifests as typical morphological features. Additionally, environmental factors can potentially interact with genetic factors, modifying the observable characteristics of the disease and affecting the symptoms, severity, and development of the condition. Notably, headaches, neck pain, dizziness, and neurological deficits may be exhibited by individuals with CM 1, highlighting the importance of early diagnosis. Magnetic resonance imaging (MRI) serves as an alternative diagnostic technique for monitoring the symptoms of CM 1. Multiple genetic factors are likely to contribute to a cascade of abnormalities in CM 1. Early studies provided evidence, including clustering within families, bone development, and co-segregation with known genetic syndromes, establishing CM 1’s association with a genetic basis. Furthermore, surgery is the only available treatment option to alleviate symptoms or hinder the progression of damage to the central nervous system (CNS) in CM 1 cases.

What drives the profitability of banking sectors in the European Union? The machine learning approach
Authors: Bernardelli Michał , Korzeb Zbigniew , Niedziółka Paweł
Published: September 2024

The study aims to establish patterns of relations between the profitability of the European Union (EU) banking sectors between 2007 and 2021 and sets of variables appropriate for clusters of countries into which the 27 countries of the EU are divided. The random forest method is deployed to identify the factors influencing the value of the return on equity. Shapley additive explanations are exploited to add interpretability to the results. The results show that the sets of variables shaping the profitability of banking sectors in the EU grouped by use of sovereign rating criterion are different. However, there are variables common to all banking sectors. These include cost efficiency and default risk. The study’s novelty lies in the reliance on a broad spectrum of explanatory variables assigned to three groups of factors, reference to all EU countries, and decomposition of the sample to identify similarities among the determinants of profitability.
Electrifying the Last Mile Delivery by Eco-Efficiency Analysis: Case Study of Latvia
Authors: Scedrovs Aleksandrs , Mendzins Karlis , Barisa Aiga , Feofilovs Maksims
Published: September 2024

The demand for e-commerce platforms has rapidly increased over the last years leading to increase demand on last mile delivery (LMD) services. Not to fall short of 2030 greenhouse gas (GHG) emission targets in the transport sector transitioning to sustainable LMD solutions is the key. Adopting electric vehicles (EVs) in delivery services can significantly reduce direct and indirect emissions, which can be of interest for many supply chain actors willing to report their sustainability practices within Scope 3 as per IPCC guidelines for the upcoming Corporate Sustainability Reporting Directive. This study undertakes the eco-efficiency analysis of a local LMD company in Latvia to understand the financial viability and the external environmental cost related to fleet electrification. As a result, the eco-efficiency analysis confirms the financial and environmental advantages of EVs. The study acknowledges limitations in the current eco-efficiency framework related to the GHG emissions monetisation and recommends leveraging the voluntary carbon credit markets for a more market-based assessment of carbon pricing. The findings support the transition towards sustainable LMD options, aligning with broader sustainability goals.

Design and performance evaluation of multilevel inverter for solar energy systems and electric vehicle charging with multi output active clamp forward converter
Authors: Adupa Chandramouli , Siva Chidambaranathan V.
Published: September 2024

This paper addresses the challenges of achieving efficient and high-quality power conversion in solar energy systems and electric vehicle (EV) charging applications by introducing a Multi-Output Active Clamp Forward Converter (MOACFC). The proposed system is designed to generate symmetrical and asymmetrical DC voltage configurations for a Multilevel Inverter (MLI) topology. Traditional MLI topologies often require numerous switches and DC sources, leading to increased complexity and reduced efficiency. To overcome these limitations, the MOACFC delivers multiple output voltages from a single solar generation input, effectively reducing the number of switches and DC sources required. This study also highlights the application of a Recurrent Neural Network Incremental Conductance (RNN-INC)-based Maximum Power Point Tracking (MPPT) algorithm to optimize power extraction from photovoltaic (PV) arrays. The MLI system’s fundamental module can produce 9-level, 21-level, and 31-level outputs, with the Nearest Level Control Pulse Width Modulation (NLCPWM) and Level Shifted Pulse Width Modulation (LSPWM) techniques employed to minimize Total Harmonic Distortion (THD). The results demonstrate significant improvements in power quality, with THD levels reduced to 3.77% in voltage and 0.99% in current for EV charging applications – substantially better than conventional 2-level and 3-level inverters. The findings indicate that the proposed MOACFC-MLI system is a more efficient and reliable alternative, offering enhanced power quality and reduced electrical stress on EV battery systems.

We performed a meta-analysis of published original studies to assess the impact of tofacitinib in plaque psoriasis or psoriatic arthritis therapy based on seven randomised controlled trials (RCTs) involving 2,672 patients (receiving tofacitinib) and 853 controls (receiving placebo).

Results

Compared with placebo, the treatment of 5 mg twice-daily (BID) tofacitinib for 12 weeks is sufficient to significantly alleviate the main clinical manifestations of psoriasis [≥75% decrease in Psoriasis Area and Severity Index score (PASI 75): Risk ratio (RR)=4.38 (95% Confidence interval (CI) 2.51 to 7.64); ≥90% decrease in PASI score (PASI 90): RR=21.68 (95% CI 4.20 to 111.85); Physician’s Global Assessment of ‘clear’ or ‘almost clear’ (PGA 0/1): RR=3.93 (95%CI 3.03 to 5.09)]. Interestingly, there was no significant difference in improvement in PGA 0/1 with 5 mg BID tofacitinib given for 16 weeks when compared with 5 mg BID tofacitinib for 12 weeks [RR=1.11 (95%CI 0.98 to 1.25)]. Additionally, the 5 mg BID tofacitinib for 16 weeks treatment schedule significantly increased the incidence of upper respiratory tract infection (URTI) [RR=1.89 (95%CI 1.06 to 3.38)] as compared to 5 mg BID tofacitinib for 12 weeks treatment schedule [RR=1.15 (95%CI 0.60 to 2.20)].

Conclusion

The 5 mg BID tofacitinib for 12 weeks treatment significantly improved psoriasis without causing too many specific adverse events. This indicated that tofacitinib is an effective treatment plan for psoriatic disease by reasonably controlling dosage and dosing time.
Correlation between epicardial fat thickness and maximum oxygen utilisation in obese adult males: A cross-sectional study
Authors: Suryawanshi Gaurav , Singh Satyajit , Ingle Avinash S. , Khandelwal Ekta
Published: September 2024

Objectives:

In general, the accumulation of fats causes a decrease in exercise tolerance. The effect of various obesity parameters on exercise tolerance is not clear. Theoretically, epicardial fat is an energy source for myocardial contraction but also releases pro-inflammatory factors, limiting coronary blood flow. No data are available about the influence of epicardial fats on exercise tolerance.

Materials and Methods:

The present cross-sectional study was conducted on 31 obese males aged 25–35. The parameters recorded were body mass index (BMI), waist-to-hip ratio (W/H ratio), and percentage body fat (%BF), which were calculated by measuring skinfold thickness at various standard sites. To determine aerobic exercise performance, VO2 max was determined using a treadmill. The epicardial fat thickness (EFT) was measured by echocardiography, at short and long axis.

Results:

Demographic values for 31 subjects BMI (26.50 ± 1.34) kg/m2, W/H ratio (1.02 ± 0.013) and %BF (25.09 ± 4.29) showed obesity. The EFT on ultrasound showed EFT at the short axis (3.45 ± 1.39 mm) and EFT at the long axis (3.09 ± 1.24 mm). Cardiopulmonary exercise testing showed an estimated VO2 max (32.74 ± 5.38 mL/kg/min) for 31 subjects. On Pearson’s correlation analysis and multivariate linear regression analysis, it was noted that only the EFT at the short axis showed a statistically significant negative correlation with VO2 max (P < 0.05), along with 13.7% of independent prediction.

Conclusion:

The results suggested that epicardial fat (measured in short axis view) plays an important role as a limiting factor for exercise affecting aerobic capacity, particularly in obese young adults.
Correlation between clinical outcome and nerve conduction studies before and after surgery in patients with carpal tunnel syndrome
Authors: Chowdhury Debanjana , Sen Sangita
Published: September 2024

Objectives:

In this study, we aimed to establish the correlation between clinical outcomes using a self-administered Boston carpal tunnel questionnaire (BCTQ) and nerve conduction studies (NCSs) before and after carpal tunnel release (CTR) operation in moderate, severe and extreme groups of patients. In prevalent literature, we found conflicting reports regarding the correlation, so we undertook this study to get a clear concept of the correlation between BCTQ and NCS.

Materials and Methods:

Thirty-two patients (39 hands) of carpal tunnel syndrome (CTS) were subdivided into three categories: Group I is moderate CTS (n = 9 hands), Group II is severe CTS (n = 14 hands) and Group III is extreme CTS (n = 16 hands). We evaluated electrophysiological parameters using both conventional motor parameters such as distal motor latency (DML), forearm conduction velocity (FMCV) and short-segment NCS parameter – transcarpal motor conduction velocity (TMCV) in pre-surgical and 6- and 9-month’s post-operative patients. The correlation between BCTQ consisting of symptom severity scale (SSS), functional status scale (FSS), and NCSs before and after CTR was assessed using Spearman rank correlation coefficients to establish the importance of CTR as the most effective treatment modality for CTS patients.

Results:

We found a significant correlation between BCTQ parameters – SSS and FSS and motor NCS parameters – DML, FMCV and TMCV in all three groups of CTS patients preoperatively, but the Spearman correlation coefficient value decreased and became statistically non-significant after 6 and 9 months of CTR operation. The BCTQ parameters SSS and FSS are influenced by the subjective information provided by the patients, whereas NCS is the objective and quantitative method to evaluate the condition of the median nerve. Moreover, NCS should be included in the post-operative follow-up to eliminate the possibility of recurrence, inadequate release of transverse ligament compressing the median nerve, and presence of other similar pathology or post-CTR complications.

Conclusion:

We can, therefore, conclude that clinicians should use BCTQ and NCS together to ascertain the success of CTR operation.
The home-based mirror therapy in the reduction of phantom limb pain in unilateral below-knee amputees
Authors: Shariaty Sadra , Taheri Alireza
Published: September 2024

Objectives:

Phantom limb pain (PLP) is a common issue for amputees, leading to various long-term challenges. Mirror therapy, a low-risk and cost-effective treatment, can be done at home. This study evaluates the effect of home-based mirror therapy on PLP in unilateral below-knee amputees.

Materials and Methods:

The study included 16 male participants, aged 18 and above. They were randomly assigned to either the mirror therapy group or the control group (prosthesis use). The mirror therapy group received a single training session (15–30 min). Then, they did exercises at home for at least 15 min a day for four weeks. They also had to use their prosthesis for at least 3 h daily. Weekly phone or online check-ins recorded pain levels. Pain was measured using the Visual Analog Scale (VAS).

Results:

Participants had a mean age of 45.12 years, and initial VAS pain scores ranged from 3 to 10. After 4 weeks, the mirror therapy group showed a 37.5% reduction in pain (P < 0.05). The control group did not experience a significant pain change (P > 0.05).

Conclusion:

Mirror therapy is a promising option for managing PLP. It supports the benefits of telehealth and home-based exercises, reducing the need for in-person consultations.
Life Interrupted: The Effects of Technology-Mediated Work Interruptions on Work and Nonwork Outcomes
Authors: Chen Adela , Karahanna Elena
Published: September 2024

Work interruptions have made significant inroads into the knowledge workers’ nonwork domain, in large part due to the ubiquitous nature of mobile devices that blur the work–nonwork boundaries by enabling work interruptions anywhere and at any time. We examine the effects of such technology-mediated work-related interruptions that occur during one’s time off on both work and nonwork outcomes. Leveraging theoretical perspectives from interruption, work–life interface, and conservation of resources, we conceptualize both positive and negative effects of such interruptions on behavioral and psychological outcomes. We identify three mediating mechanisms via which these effects occur: interruption overload and psychological transition via which negative effects occur and task closure via which positive effects occur. Results reveal significant effects of interruptions on work and nonwork outcomes through the three mediating mechanisms. Although positive effects are observed, the total effects of work-related interruptions are detrimental across both work and nonwork outcomes, with the strongest negative effect on work exhaustion. The results suggest that after-hours work interruptions do not necessarily benefit work performance and come at the cost of work exhaustion. Analyses also reveal that the effects of interruptions are dependent on the technology via which these occur. While phone and messaging generate negative outcomes through interruption overload, e-mail leads to both positive and negative outcomes through task closure and psychological transition respectively. The study concludes with implications for research and practice on how to mitigate negative effects and enhance positive effects.
