A New Zero Waste Design for a Manufacturing Approach for Direct-Drive Wind Turbine Electrical Generator Structural Components

An integrated structural optimization strategy was produced in this study for direct-drive electrical generator structures of offshore wind turbines, implementing a design for an additive manufacturing approach, and using generative design techniques. Direct-drive configurations are widely implemented on offshore wind energy systems due to their high efficiency, reliability, and structural simplicity. However, the greatest challenge associated with these types of machines is the structural optimization of the electrical generator due to the demanding operating conditions. An integrated structural optimization strategy was developed to assess a 100-kW permanent magnet direct-drive generator structure. Generated topologies were evaluated by performing finite element analyses and a metal additive manufacturing process simulation. This novel approach assembles a vast amount of structural information to produce a fit-for-purpose, adaptative, optimization strategy, combining data from static structural analyses, modal analyses, and manufacturing analyses to automatically generate an efficient model through a generative iterative process. The results obtained in this study demonstrate the importance of developing an integrated structural optimization strategy at an early phase of a large-scale project. By considering the typical working condition loads and the machine’s dynamic behavior through the structure’s natural frequencies during the optimization process coupled with a design for an additive manufacturing approach, the operational range of the wind turbine was maximized, the overall costs were reduced, and production times were significantly diminished. Integrating the constraints associated with the additive manufacturing process into the design stage produced high-efficiency results with over 23% in weight reduction when compared with conventional structural optimization techniques.

Medication stewardship in the operating theatre in Malaysia: A quality improvement project.

A quality improvement project ('Safe Anaesthesia for ALL-SEAL') was implemented to reduce preventable medication errors and drug wastage in the operating theatre (OT) of a tertiary hospital. The primary objective of this quality improvement project was to prevent the incidence of medication errors, and the secondary objective was to reduce the wastage of unused drugs. A pre-intervention questionnaire and an audit survey were performed, and multidirectional interventions were designed post-survey. A post-intervention survey was conducted to evaluate effectiveness. The incidence of medication errors, including near misses, was assessed for root causes. Unused drugs drawn or diluted in syringes were recorded daily in each OT. The weekly drug orders and mid-week reordering frequency were also monitored. The data were reported as simple means and percentages. Ninety-eight anaesthesia care providers participated in the survey (72.4% doctors and 27.6% anaesthetic nurses). Pre-intervention, 76.1% of respondents had experienced medication errors during their practice. Common errors included misidentification of ampoules or vials (65.2%), miscalculation of dosages (65.2%), improper syringe labelling (56.5%), accidental drug omission (54.3%) and wrong prescriptions (39.1%). The main sources of errors were fatigue/overwork (80.4%) and a hectic OT environment (71.7%). Post-intervention, no incidents of medication errors were reported. In addition, there was a significant reduction in drug wastage. The SEAL project positively prevented medication errors and reduced drug wastage, which should be further validated in other clinical settings.

Community Participation in Ecotourism Project Development: In Wof-Washa National Priority Forest Area

The study focused on investigations of community participation in ecotourism development in Wof-Washa National Priority Forest Areas, using a descriptive design with mixed approach through cross-sectional survey. The study utilized systematic, stratified, and purposeful sampling methods. It also used thematic analysis for qualitative data collected through interviews, and descriptive statistics for quantitative data gathered via questionnaires. Document reviews were used to triangulated this study result with previous findings. The study findings reveal that the current status of community involvement in ecotourism development lean toward degree of tokenism (moderate level), with limited roles, as Arnstein's model, at all stages. Generally, without the participation of community, the development of ecotourism project couldn’t be possible. The researcher suggests that collaborative efforts among all relevant stakeholders are crucial to fostering community participation in the successful implementation of the ecotourism project in Wof-Washa National Priority Forest Area.

Sketching the spatial disparities in heatwave trends by changing atmospheric teleconnections in the Northern Hemisphere

Pronounced spatial disparities in heatwave trends are bound up with a diversity of atmospheric signals with complex variations, including different phases and wavenumbers. However, assessing their relationships quantitatively remains a challenging problem. Here, we use a network-searching approach to identify the strengths of heatwave-related atmospheric teleconnections (AT) with ERA5 reanalysis data. This way, we quantify the close links between heatwave intensity and AT in the Northern Hemisphere. Approximately half of the interannual variability of heatwaves is explained and nearly 80% of the zonally asymmetric trend signs are estimated correctly by the AT changes in the mid-latitudes. We also uncover that the likelihood of extremely hot summers has increased sharply by a factor of 4.5 after 2000 over areas with enhanced AT, but remained almost unchanged over the areas with attenuated AT. Furthermore, reproducing Eastern European heatwave trends among various models of the Coupled Model Intercomparison Project Phase 6 largely depends on the simulated Eurasian AT changes, highlighting the potentially significant impact of AT shifts on the simulation and projection of heatwaves.

Ramanov Contractors: Adoption of Project Risk Management Framework

The case deals with the concept of project risk management and its adoption in a small-sized contracting firm. It demonstrates the dilemma faced by a typical small-sized contracting firm vis-à-vis setting project objectives, defining key elements for structuring the risk management process, number of data points, choice of techniques of different steps involved in project risk management and development of a team to practice the process flawlessly. The case would be suitable for postgraduate students of the management programme as well as participants of management development programmes on project management.

Storylines of projected summer warming in Iberia using atmospheric circulation, soil moisture and sea surface temperature as drivers of uncertainty

This study explores the uncertainty of future summer warming over Iberia using storylines constructed from climate model simulations of the Climate Model Intercomparison Project Phase 6. Unlike prior storyline approaches focusing on remote drivers and global teleconnections of atmospheric circulation, we use regional factors that directly influence summer temperatures: ridging activity, soil moisture and Mediterranean sea surface temperature. These drivers explain a substantial portion of the observed variability across climate models, with ridging activity and soil moisture showing the strongest influence on Iberian warming. Under a high radiative forcing scenario (SSP5–8.5), the storylines of Iberian warming based on these two drivers range between 7 and 9 °C for the end of the 21st century. The storyline leading to the largest warming is characterised by a drying out of the soil conditions and an increase in the anticyclonic activity over Iberia. We find similar conclusions for simple extreme heat indicators, though the approach struggles with more complex heatwave metrics. We also propose a novel modification of the storyline approach to increase the data sample of climate responses by using different time intervals throughout the 21st century. This modification would allow the application of more complex statistical models, the exploration of non-linear relationships and the identification of other drivers shaping the regional climate projections.

Pharmaceutical innovation collaboration, evaluation, and matching

This paper theoretically studies pharmaceutical innovation collaborations, where heterogeneous firms compete for heterogeneous academics. At an interim stage, the firm evaluates the project, which allows it to monitor academics and decide whether to terminate the project to avoid the loss from a future failure. This paper explores the contract, project termination strategy, and collaboration matching. The firm’s innovation strategy (exploitations or explorations) determines the evaluation structure, which may affect the market equilibrium. By considering different innovation strategies, this paper shows that in each case, the equilibrium matching is unique (either positive or negative assortative). Consequently, the chosen innovation strategy plays a pivotal role in shaping equilibrium matching outcomes. These findings provide theoretical insights into pharma-academic alliances, shed light on the observed positive or negative assortative properties in the market, and advocate for the consideration of innovation strategies and evaluation structures in future research endeavors. Moreover, this paper also provides several empirical and policy implications.

Interdisciplinary perspective on architectural programming: current status and future directions

PurposeArchitectural programming, as a critical phase in construction projects, has been widely recognized for its importance and advantages throughout the construction process.

Perspectives on improving wound care for Aboriginal health workers in rural and remote communities in Queensland, Australia

BackgroundThe care of wounds is an ongoing issue for Indigenous people worldwide, yet culturally safe Indigenous wound care training programs for rural and remote Australian Aboriginal Health Workers are largely unavailable. The higher prevalence of chronic disease, lower socioeconomic status and poorer access to services experienced by Aboriginal and Torres Strait Islanders compared to non-Indigenous people, leads to a greater incidence of chronic wounds in Aboriginal and Torres Strait Islander people. Identifying the barriers and enablers for delivering wound care will establish areas of need for facilitating the development of a specific wound care program for Aboriginal Health Workers and Aboriginal Health Practitioners. This paper reports the first phase of a larger project directly aligned to the Indigenous Australians’ Health Program’s objective of supporting the delivery and access to high quality, culturally appropriate health care and services to Aboriginal and Torres Strait Islander Australians. This study aimed to examine experiences of Aboriginal Health Workers, Aboriginal Health Practitioners, and nurses for managing chronic wounds within rural and remote Aboriginal Medical Services in Queensland, Australia.MethodsYarning facilitated by two Aboriginal researchers among Aboriginal Health Workers, Aboriginal Health Practitioners, and nurses currently employed within four Aboriginal Medical Services located in rural and remote areas of Queensland, Australia.ResultsTwo themes were developed through rigorous data analysis of yarning information and responses: participants’ experiences of managing wounds and barriers and enablers to effective wound care.ConclusionsThis study contributes an insight into the experiences of Aboriginal Health Workers on the current barriers and enablers to timely treatment of chronic wounds. Results from this study indicate a significant barrier to obtaining timely and effective wound care in regional and remote settings is access to an appropriately skilled, culturally competent, and resourced health work force. A lack of education and professional development for Aboriginal Health Workers can compromise their ability to maximise patient outcomes and delay wound healing. Findings have informed the development of an evidence based, culturally competent open access chronic wound care education program for Aboriginal Health Workers.

Exploring autonomic dysfunction in functional dysphonia: A protocol for a case-control study and a randomized controlled trial.

Although psychological factors have been implicated in patients with functional dysphonia (FD), conventional voice therapy (CVT) typically targets the aberrant voice symptoms exclusively. Yet, CVT is not always successful, and in view of the significant adverse quality of life impact combined with the financial burden on the healthcare system and society, research is needed to elucidate the underlying psychophysiology of FD and improve treatment outcomes. The first objective of this research project is to compare the occurrence and frequency of symptoms and/or disorders related to autonomic nervous system (ANS) dysfunction in patients with FD with gender- and age-matched vocally healthy controls, using a case-control study. The second objective is to compare the effects of a novel therapy for FD based on ANS regulation (i.e., ANS therapy: heart rate variability (HRV) biofeedback) on both autonomic function and voice function versus CVT alone or in combination with ANS therapy (i.e., ANS therapy + CVT), using a randomized controlled trial (RCT). Case-control study: Autonomic (dys)function of patients with FD will becompared with gender- and age-matched vocally healthy controls, using both physiological measures (e.g., HRV, skin conductance level) and psychological patient-reported outcome measures (PROMs, e.g., Neuroception of Psychological Safety Scale, Depression Anxiety and Stress Scale). RCT: The FD group will be randomly assigned to the innovative ANS therapy group, the CVT group or the ANS therapy + CVT group. All patients received 1 month of treatment with 20 min of daily practice. Both the autonomic assessment and the voice assessment will beperformed pretherapy and immediately after therapy by assessors blinded to group allocation and study phase. Higher occurrences of symptoms and/or disorders related to autonomic dysfunction are expected in patients with FD compared with vocally healthy controls. Physiological outcomes: lower HRV, lower cardiac pre-ejection period, higher respiration rate and higher skin conductance level are hypothesized in patients with FD compared with vocally healthy controls. Psychological PROMs: higher self-report of feelings/symptoms related to autonomic dysfunction (e.g., perceived stress, anxiety) is expected in patients with FD compared with vocally healthy controls. The autonomic function is hypothesized to improve more after the ANS therapy and the ANS therapy + CVT compared with the CVT only. Voice function is expected to improve more after the ANS therapy + CVT compared with the ANS therapy and the CVT alone. What is already known on the subject Autonomic dysfunction is well recognized in the field of psychology but remains understudied in the area of voice. Given that the vagus nerve, innervating the larynx, also helps to regulate the ANS, and psychological symptoms commonly observed in patients with FD may reflect ANS dysregulation, research in this area is needed. There is some preliminary evidence that autonomic dysfunction might indeed be associated with FD. However, physiological ANS measures are needed, as well as validated psychological PROMs. What this paper adds to the existing knowledge The first objective of this study is to investigate the occurrence and frequency of symptoms and/or disorders related to autonomic dysfunction in patients with FD as compared with a gender- and age-matched vocally healthy control group. Autonomic (dys)function will be determined by employing both physiological measures (e.g., HRV, skin conductance level) and psychological PROMs (e.g., Neuroception of Psychological Safety Scale, Depression Anxiety and Stress Scale). The second objective is to compare the effects of a novel therapy for FD based on ANS regulation (HRV biofeedback) versus CVT alone or in combination with ANS therapy. What are the potential or actual clinical implications of this work? Success rates of symptomatic CVT for FD are highly variable. This study is expected to lead to innovative results related to the pathogenesis and psychophysiology of FD, a prevalent voice disorder associated with a significant adverse quality of life impact and a substantial financial burden on the healthcare system and society. The results of this study will lead to crucial new insights into both the diagnosis and treatment of FD, contributing to evidence-based practice in the field of voice.

Challenges Experienced by Health Care Workers During Service Delivery in the Geographically Challenging Terrains of North-East India: Study Involving a Thematic Analysis.

The public health landscape in North-East India is marked by the foundational principle of equitable health care provision, a critical endeavor considering the region's intricate geography and proximity to international borders. Health care workers grapple with challenges, such as treacherous routes, limited infrastructure, and diverse cultural nuances, when delivering essential medical services. Despite improvements since the National Rural Health Mission in 2005, challenges persist, prompting a study to identify health care workers' challenges and alternative strategies in Manipur and Nagaland. This study aims to document the challenges experienced by health care workers during service delivery in the geographically challenging terrains of North-East India. This study is part of the i-DRONE (Indian Council of Medical Research's Drone Response and Outreach for North East) project, which aims to assess the feasibility of drone-mediated vaccine and medical delivery. This study addresses the secondary objective of the i-DRONE project. In-depth interviews of 29 health care workers were conducted using semistructured questionnaires in 5 districts (Mokokchung and Tuensang in Nagaland, and Imphal West, Bishnupur, and Churachandpur in Manipur). Nineteen health facilities, including primary health care centers, community health centers, and district hospitals, were selected. The study considered all levels of health care professionals who were in active employment for the past 6 months without a significant vacation and those who were engaged in ground-level implementation, policy, and maintenance activities. Data were recorded, transcribed, and translated, and subsequently, codes, themes, and subthemes were developed using NVivo 14 (QSR International) for thematic analysis. Five themes were generated from the data: (1) general challenges (challenges due to being an international borderline district, human resource constraints, logistical challenges for medical supply, infrastructural issues, and transportation challenges); (2) challenges during the COVID-19 pandemic (increased workload, lack of diagnostic centers, mental health challenges and family issues, routine health care facilities affected, stigma and fear of infection, and vaccine hesitancy and misinformation); (3) perception and awareness regarding COVID-19 vaccination; (4) alternative actions or strategies adopted by health care workers to address the challenges; and (5) suggestions provided by health care workers. Health care workers demonstrated adaptability by overcoming these challenges and provided suggestions for addressing these challenges in the future. Health care workers in Manipur and Nagaland have shown remarkable resilience in the face of numerous challenges exacerbated by the pandemic. Despite infrastructural limitations, communication barriers, and inadequate medical supply distribution in remote areas, they have demonstrated adaptability through innovative solutions like efficient data management, vaccination awareness campaigns, and leveraging technology for improved care delivery. The findings are pertinent for not only health care practitioners and policymakers but also the broader scientific and public health communities. However, the findings may have limited generalizability beyond Manipur and Nagaland.

Delays Factors for Construction Projects in South of Iraq

This study seeks to identify and categorize the factors responsible for delays in construction projects in southern Iraq. Using a sequential research approach that includes a literature review, interviews, and surveys, data were collected from 115 industry professionals, including clients, consultants, project managers, contractors, and engineers. The analysis utilized both descriptive and conclusive statistical methods, with a specific emphasis on the Spearman rank correlation coefficient to verify the reliability of the delay factor rankings. The research identified 45 major delay factors, with the most critical being global and local economic crises, bureaucracy and corruption, public holidays, delays in securing municipal permits, and frequent change orders initiated by clients. These factors were further classified into eight categories: inaccuracies in the tendering process, technical performance management, government interference, rework in construction practices, among others. The results indicate strong consensus among the different respondent groups regarding the main causes of project delays, as demonstrated by high correlation coefficients and a Chi-squared test confirming the agreement's significance. The findings provide valuable insights for practical applications and academic research, supporting the selection of project leaders, anticipating potential delays, and improving project management practices in Iraq. The study suggests future research should focus on strategic economic planning, exploring alternative funding sources, combating corruption, and implementing regulatory reforms to address the identified delay factors.

Investigating and evaluating the impact of COVID-19 and post-COVID-19 response measures on construction projects in Iraq

Abstract. At the end of 2019, the whole world was exposed to a major health crisis, which the Coronavirus, which went out of the control of all countries, including Iraq, The negative impact of the coronavirus pandemic continues to this day on the construction industry sector in Iraq. This research aims to study and find the most common risk factors for the Coronavirus crisis and analyze them using the descriptive analysis method (HEAT MAP), in addition to identifying, analyzing and evaluating response procedures after Covid-19 by finding the relative importance index (RII). The factors of the Covid-19 crisis were extracted and the most common different response procedures were found from the archives of (24) completed construction projects in the projects of the University of Kufa, Karbala and Babylon. The current practice and the possibility of occurrence of risk factors, their severity and the possibility of their occurrence were diagnosed by conducting interviews accompanied by an open questionnaire with (15) Iraqi experts concerned with construction project management and then directing a detailed closed questionnaire to (140) others. All the results obtained were subjected to statistical tests to verify their validity, and the results showed the presence of (37) factors related to the Coronavirus, with the identification of their characteristics and the most affected project objectives, as well as the most affected contracting parties. When using the (HEAT MAP) method, it was found that the group of political risk factors is dominant and that the most harmful factors are the curfew and changes in the current government policies followed to combat the epidemic, curfew decisions and changes in the current government policies followed to combat the epidemic, political division, conflicting decisions, and the absence of plans and preparation for such crises. The delay in state funding for funded projects in the Middle Euphrates due to strict measures in the Middle Euphrates by the government that has existing projects was the most harmful. When applying (RII) to find the most important response measures, it was holding regular working sessions to discuss COVID-19 policies and response mechanisms, imposing a state of emergency due to the Corona virus as a force majeure, and finally cooperating with regulatory bodies to facilitate policy changes as well as enhancing scientific advice. Through this study, the project reached many conclusions and recommendations that would reduce or mitigate the impact of the Corona pandemic or any future events on the objectives of any construction project.

Design and test of an X -band constant gradient structure

A light source project named very compact inverse Compton scattering gamma-ray source (VIGAS) is under development at Tsinghua University. VIGAS aims to generate monochromatic high-energy gamma rays by colliding 350-MeV electron beams with 400-nm laser photons within a 12-m beamline. To produce a high-energy electron beam in such a compact space, the system consists of an S-band high-brightness injector and six X-band high-gradient accelerating structures. The goal of the X-band structure is to operate at a high gradient of 80 MV/m. Therefore, we adopts the constant gradient traveling wave approach, where the iris from the first cell to the end cell is tapered. The structure has 72 cells, including 70 cells and 2 couplers, so we named it XT72. The frequency of XT72 is selected to 11.424 GHz, and the 2π/3 mode is adopted. In this paper, we present a comprehensive study covering the detailed design, fabrication, rf tuning, and high-power test results of the first XT72. Additionally, we compare the performance of this structure to that of the previous constant impedance structure. Our results demonstrate that the XT72 is capable of operating at an 80−MV/m gradient with a lower breakdown rate. This advancement paves the way for the development of VIGAS project and contributes to the wider application of X-band room-temperature high-gradient structures in compact accelerator facilities.

It’s About Time! Understanding the Dynamic Team Process-Performance Relationship Using Micro- and Macroscale Time Lenses

Although team processes are conceptualized as temporal phenomena, our theoretical understanding of their unfolding over time is underdeveloped, particularly when “zooming in and out” into their dynamics using different temporal lenses. Team processes might unfold differently over extended project cycles (i.e., macroscale time lens) versus over brief events (microscale time lens). Our goal was to better understand temporal changes of three critical higher-order team processes (i.e., transition, action, and interpersonal processes) over both extended periods (i.e., longer project cycles) and brief time spans (i.e., recurring stand-up meetings). Focusing on two agile software teams, we indexed team processes across these two time spans using computer-aided text analysis (CATA) of meeting transcripts. Macroscale time span processes were captured across 10 sprints (30-week project cycle). Microscale time spans were captured with data from brief stand-up meetings (i.e., using 10 equidistant time intervals from 40 meetings). From a macroscale time lens (i.e., project cycle), an increase in action processes in the early project phase was associated with increases in performance. From a microscale time lens, changes in transition and interpersonal processes around mid-meeting phases were associated with differences in performance. Qualitative analyses of meeting midpoints revealed key differences in proactive planning and interpersonal processes. We discuss how our results provide novel insights for team process dynamics in relation to micro- and macroscale time spans.

A Comprehensive Study on Young Roots of Acacia mangium Willd. Species for Soil Bioengineering

ABSTRACTSoil bioengineering has been leveraged for controlling shallow landslides and soil erosion. Acacia mangium Willd. species is widely used for soil bioengineering, but its root properties have not been extensively investigated. This study aimed to measure the various properties (i.e., morphological traits, biomechanical properties, chemical composition and root reinforcement) for establishing roots of A. mangium Willd. species through a series of laboratory experiments (i.e., rhizobox observation, uniaxial tensile test, direct shear and volumetric water content and suction monitoring). The results underscored the rapid growth (i.e., 0.43 ± 0.01 cm/day) and highlighted variations in “side” root area ratios of A. mangium Willd. species with depth. Root orientation also demonstrated a significant correlation with root diameter following a linear model (p < 0.05, R 2 = 0.39). At the early‐stage establishment (28 weeks), A. mangium Willd. roots exhibited the tensile strength, Young's modulus and mechanical reinforcement of 10.18 ± 0.62 MPa, 325.18 ± 21.72 MPa and 3.15 kPa, respectively. The presence of roots was found to increase the soil suction, air‐entry value and saturated water content of lateritic soil by improving the soil‐water characteristic curve. This work elucidated the root properties of A. mangium Willd. during the early‐stage establishment, raising caution for the design of slope‐stabilisation projects using soil bioengineering, especially during the initial phase of projects.

Multivariate bias correction and downscaling of climate models with trend-preserving deep learning

Global climate models (GCMs) and Earth system models (ESMs) exhibit biases, with resolutions too coarse to capture local variability for fine-scale, reliable drought and climate impact assessment. However, conventional bias correction approaches may cause implausible climate change signals due to unrealistic representations of spatial and intervariable dependences. While purely data-driven deep learning has achieved significant progress in improving climate and earth system simulations and predictions, they cannot reliably learn the circumstances (e.g., extremes) that are largely unseen in historical climate but likely becoming more frequent in the future climate (i.e., climate non-stationarity). This study shows an integrated trend-preserving deep learning approach that can address the spatial and intervariable dependences and climate non-stationarity issues for downscaling and bias correcting GCMs/ESMs. Here we combine the super-resolution deep residual network (SRDRN) with the trend-preserving quantile delta mapping (QDM) to downscale and bias correct six primary climate variables at once (including daily precipitation, maximum temperature, minimum temperature, relative humidity, solar radiation, and wind speed) from five state-of-the-art GCMs/ESMs in the Coupled Model Intercomparison Project Phase 6 (CMIP6). We found that the SRDRN-QDM approach greatly reduced GCMs/ESMs biases in spatial and intervariable dependences while significantly better-reducing biases in extremes compared to deep learning. The estimated drought based on the six bias-corrected and downscaled variables captured the observed drought intensity and frequency, which outperformed state-of-the-art multivariate bias correction approaches, demonstrating its capability for correcting GCMs/ESMs biases in spatial and multivariable dependences and extremes.

The stable category of monomorphisms between (Gorenstein) projective modules with applications

Abstract Let ( S , 𝔫 ) {(S,{\mathfrak{n}})} be a commutative noetherian local ring and let ω ∈ 𝔫 {\omega\in{\mathfrak{n}}} be non-zerodivisor. This paper is concerned with the two categories of monomorphisms between finitely generated (Gorenstein) projective S-modules, such that their cokernels are annihilated by ω. It is shown that these categories, which will be denoted by 𝖬𝗈𝗇 ⁢ ( ω , 𝒫 ) {{\mathsf{Mon}}(\omega,\mathcal{P})} and 𝖬𝗈𝗇 ⁢ ( ω , 𝒢 ) {{\mathsf{Mon}}(\omega,\mathcal{G})} , are both Frobenius categories with the same projective objects. It is also proved that the stable category 𝖬𝗈𝗇 ¯ ⁢ ( ω , 𝒫 ) {\underline{\mathsf{Mon}}(\omega,\mathcal{P})} is triangle equivalent to the category of D-branes of type B, 𝖣𝖡 ⁢ ( ω ) {\mathsf{DB}(\omega)} , which has been introduced by Kontsevich and studied by Orlov. Moreover, it will be observed that the stable categories 𝖬𝗈𝗇 ¯ ⁢ ( ω , 𝒫 ) {\underline{\mathsf{Mon}}(\omega,\mathcal{P})} and 𝖬𝗈𝗇 ¯ ⁢ ( ω , 𝒢 ) {\underline{\mathsf{Mon}}(\omega,\mathcal{G})} are closely related to the singularity category of the factor ring R = S / ( ω ) {R=S/({\omega)}} . Precisely, there is a fully faithful triangle functor from the stable category 𝖬𝗈𝗇 ¯ ⁢ ( ω , 𝒢 ) {\underline{\mathsf{Mon}}(\omega,\mathcal{G})} to 𝖣 𝗌𝗀 ⁡ ( R ) {\operatorname{\mathsf{D_{sg}}}(R)} , which is dense if and only if R (and so S) are Gorenstein rings. Particularly, it is proved that the density of the restriction of this functor to 𝖬𝗈𝗇 ¯ ⁢ ( ω , 𝒫 ) {\underline{\mathsf{Mon}}(\omega,\mathcal{P})} , guarantees the regularity of the ring S.

Balancing allocative and dynamic efficiency with redundant R&D allocation: The role of organizational proximity and centralization

AbstractResearch SummaryResource‐based‐view scholars have mainly examined two resource allocation approaches for competitive advantage in multiunit firms: resource sharing and resource redeployment. These approaches emphasize allocative efficiency—the optimal allocation of resources to maximize their current value. In technology‐intensive industries, firm success also requires achieving dynamic efficiency to increase its future value‐creation. We propose that the redundant allocation of resources—the parallel deployment of non‐scale‐free resources towards the same objective—although allocatively inefficient, increases dynamic efficiency by stimulating inter‐unit competition. Firms' structural features moderate these effects. An analysis of large pharmaceutical firms reveals that redundant R&D increases innovations with high firm‐specific value but simultaneously increases project terminations to reduce wastage. Organizational proximity increases the former effect and decreases the latter. Firm's R&D centralization amplifies the effect of unit proximity.Managerial SummaryIn technology‐intensive industries, multiunit firms often employ redundant allocation of R&D resources, that is, the parallel deployment of scientists and equipment in different units towards realizing the same business objective. Although common, there is little managerial guidance on how this practice impacts firms' R&D outcomes, and how organizational characteristics influence this relationship. An analysis of large pharmaceutical firms reveals that redundant allocation of R&D resources across units increases wastage but also stimulates competing units to create innovations with high firm‐specific value. Organizationally proximate units are less likely to have their redundant projects terminated, while creating more high‐value‐innovations. Centralization of the firm's R&D amplifies the effect of unit proximity.

Implementation of Site Quality Management System for a Building Construction Project

Construction industry plays an important role in the development of any country. The development of construction industry depends on the quality of construction projects. Quality is one of the critical factors in the success of construction projects. Improvement in the quality of construction projects is linked with quality management in the project life cycle. Although quality management at every stage of project life cycle is important but the quality management at the execution (construction) stage contributes significantly on final quality outcome of construction projects. This project mainly focuses the importance and factors that affects the quality management in the execution (construction) phase. The project also includes visiting of some construction companies and conducts the questionnaire survey, then analyse the difficulties (major factors) and the cost variance due to quality defect in quality management and suggests some proactive measures for the improvement of quality in the execution phase of construction projects.
