Multi-skilled worker assignment in seru production system for the trade-off between production efficiency and workload fairness
Authors: Zeng Shaoyu , Wu Yinghui , Yu Yang 
Published: March 2022

PurposeThe paper formulates a bi-objective mixed-integer nonlinear programming model, aimed at minimizing the total labor hours and the workload unfairness for the multi-skilled worker assignment problem in Seru production system (SPS).Design/methodology/approachThree approaches, namely epsilon-constraint method, non-dominated sorting genetic algorithm 2 (NSGA-II) and improved strength Pareto evolutionary algorithm (SPEA2), are designed for solving the problem.FindingsNumerous experiments are performed to assess the applicability of the proposed model and evaluate the performance of algorithms. The merged Pareto-fronts obtained from both NSGA-II and SPEA2 were proposed as final solutions to provide useful information for decision-makers.Practical implicationsSPS has the flexibility to respond to the changing demand for small amount production of multiple varieties products. Assigning cross-trained workers to obtain flexibility has emerged as a major concern for the implementation of SPS. Most enterprises focus solely on measures of production efficiency, such as minimizing the total throughput time. Solutions based on optimizing efficiency measures alone can be unacceptable by workers who have high proficiency levels when they are achieved at the expense of the workers taking more workload. Therefore, study the tradeoff between production efficiency and fairness in the multi-skilled worker assignment problem is very important for SPS.Originality/valueThe study investigates a new mixed-integer programming model to optimize worker-to-seru assignment, batch-to-seru assignment and task-to-worker assignment in SPS. In order to solve the proposed problem, three problem-specific solution approaches are proposed.

Authors: Martin Jason 
Published: March 2022

PurposeAn effective measurement of library leadership is crucial to understanding the current state of library leadership and to developing library leaders. This study sought to validate and measure the reliability of the Martin Library Leadership survey.Design/methodology/approachThis survey is based on the Martin Library Leadership Definition, an evidence-based definition of library leadership. The first version of the survey consisted of 28 questions plus questions on respondent and library leader demographics. Each question measured one of the three components of the definition. This version of the survey was distributed to multiple ALA listservs and after analysis 16 items were removed. The resulting 12 question version of the survey was sent to the same ALA listservs and completed by 291 librarians and library staff from various library types and library work areas. The responses were analyzed using SPSS.FindingsExploratory factor analysis found three factors that align with the three components of the Martin Library Leadership Definition, and questions loaded in their expected factors at least 0.7. Cronbach's alpha was used to determine internal consistency. The alpha for the entire survey was 0.956. The Martin Library Leadership survey was validated and found to be reliable.Originality/valueThe results of this study provide strong and consistent evidence the Martin Library Leadership survey is valid and can be used in further library leadership research and professional development.

Published: March 2022

Purpose
The COVID-19 pandemic has resulted in significant changes in tourists’ attitudes and behaviors mostly as a result of confinement-related problems. Although various studies have been conducted to analyze customers’ perceptions of service quality and satisfaction using a drop-off/pick-up method, the influence of COVID-19 on customers’ perceptions of service quality and satisfaction has not been examined using online reviews. It is critical to evaluate satisfaction aspects from user-generated content to ascertain their preferences for hotel services during the pandemic. This research aims to explore the viewpoint shared online by hotel tourists, as well as identify which service practice is associated with higher and lower satisfaction during the COVID-19 pandemic.

Soil respiration response to nitrogen fertilization experiment in tropical grassland
Authors: Verma Preeti , Sagar R. 
Published: March 2022

AbstractWe examined the response of soil respiration (SR) to nitrogen (N) input using a manipulation experiment in a tropical grassland. Studying the influence of N‐input on the SR is important under sustainable agricultural strategies and future climate change. The response of SR is expected to vary in each ecosystem; therefore, manipulation experiments in many ecosystems and subsequent synthesis can be a significant strategy for climate change mitigation and adaptation. We hypothesized that the higher levels of N‐input suppress the SR by reducing soil‐C, species diversity, and biomass of the roots and microbes. For this study, seventy‐two 1 × 1–m experimental plots (equally divided into six N‐levels; each with 12 replicates) were established in 2013 on the campus of the Banaras Hindu University, India. On monthly basis, six levels of N (0, 30, 60, 90, 120, and 150 kg N ha−1 year−1) were applied to the plots. Soil and vegetation data were collected for 3 years and analyzed using statistical methods. The SR (mg m−2 h−1) ranged between 156 and 197 and significantly varied across the N‐inputs. Analysis revealed 85 kg N ha−1 year−1 input is needed for the maximum SR because of higher contents of microbial biomass, soil‐C, plant diversity, root biomass, and fast decomposition of the litters. The N‐input beyond 85 kg ha−1 year−1 inhibited the SR due to N‐induced soil acidification to the microbes and plants. We conclude that the SR of the tropical grassland ecosystem is synergistically governed by the N‐input‐modulated indirect effects of the soil and vegetation traits.

AbstractAdaptation to local pollination regimes and secondary contact of allopatrically differentiated populations with respect to pollination ecology may result in geographical variation in floral traits. We examined the contributions of these two processes in Isodon shikokianus, which showed remarkable geographical variation in corolla tube length in western Japan. Corolla tube length varied among 17 study populations located within a relatively narrow area, and covaried with altitude and distribution of two bumblebee pollinators with different tongue lengths: the longer corolla was found at lower altitudes where the long‐tongued pollinator was more abundant, and vice versa. Additionally, bumblebee species preferentially visited flowers that fit their tongue lengths. Population genetic analysis based on 11 microsatellite loci revealed that populations with long and short corolla tubes constituted genetically distinct groups. Migration rates were low between the groups, but high within each group. These results indicate that two genetically differentiated groups made secondary contact and hybridized, and gene flow between the groups was limited. Thus, the geographical variation in corolla tube length in I. shikokianus may be a result of past allopatric differentiation and subsequent secondary contact of populations with different corolla tube lengths. The variation in corolla tube length within a narrow area may be maintained by selection owing to the altitudinally structured pollinator assemblages. Altitudinal differences in relative abundance of two pollinators and their assortative visitation with respect to corolla tube length may contribute to reproductive isolation between the two groups.
The Dynamics of Sino‐Iranian Relations: Strategic Veneer, Intrinsic Tensions and Third‐party Leverage
Authors: Parchami Ali 
Published: March 2022

AbstractSino‐Iranian relations are transactional, asymmetrical, and constrained by divergent interests and priorities. Iran's isolation and depressed economy make it a risky if inexpensive investment for Beijing, whereas Iranian critics view China as self‐serving and opportunistic. Although stability and cooperation are integral to China's Middle East strategy, Iran is a revisionist actor that promotes regional dissonance and instability. These intrinsic tensions do not detract from an important but less palpable dimension of Sino‐Iranian relations: By deliberately cultivating an air of ambiguity around their cooperation and its future prospects, both countries have been exploiting their bilateral ties as leverage with third parties.

AimsThe aim was to quantify the relationship between pharmacist intervention and vancomycin‐associated acute kidney injury (AKI).MethodsElectronic databases were searched up to August 2020 for meta‐analyses of cohort studies and/or randomized controlled trials. Studies that compared the incidence of AKI in patients between post‐ and prepharmacist intervention were investigated. The primary outcome was incidence of AKI. We also evaluated the influence of pharmacist intervention in risk factors of vancomycin‐associated AKI.ResultsThe search strategy retrieved 1744 studies and 34 studies with 19 298 participants were included (22 published articles and 12 abstracts from conference proceedings). Compared with the preintervention group, the postintervention group patients had a significantly lower incidence of vancomycin‐associated AKI: 7.3% for post‐ and 9.6% for preintervention (odds ratio [OR] 0.52, 95% confidence interval [CI]; 0.41, 0.67], P < .00001). The rate of attaining target concentration was significantly higher in the post‐ than preintervention group (OR 2.86, 95% CI [2.23, 3.67], P < .00001). The postintervention group significantly improved the percentage of serum creatinine laboratory tests than preintervention group (OR = 3.24, 95% CI 2.02, 5.19], P < .00001). Patients postintervention had markedly lower risk of mortality than preintervention patients (OR 0.47, 95% CI [0.31, 0.72], P = .0004).ConclusionPharmacist intervention in vancomycin treatment significantly decreased the rate of vancomycin‐associated AKI, while improving efficacy and reducing mortality. We speculate that this is because the pharmacist interventions optimized the rationality of vancomycin therapy, monitoring of vancomycin trough concentration and the monitoring of patients' renal function.
Neoadjuvant chemotherapy in patients undergoing colonic resection for locally advanced nonmetastatic colon cancer: A nationwide propensity score matched cohort study
Authors: Laursen Magnus , Dohrn Niclas , Gögenur Ismail , Klein Mads Falk 
Published: March 2022

AbstractAimNeoadjuvant chemotherapy (NCT) for nonmetastatic colon cancer is not routinely used, and is currently only recommended as a treatment option for a subgroup of patients with T4b colon cancers in clinical guidelines. However, NCT may cause downstaging of the tumour, increase resectability, eradicate micrometastases and thereby improve long‐term outcomes for patients with nonmetastatic colon cancer. The aim of this study was to investigate the short‐term postoperative outcomes in a nationwide cohort of patients with locally advanced colon cancer (LACC) receiving NCT.MethodUsing the Danish Colorectal Cancer Group Database, data were retrieved on patients diagnosed with LACC (defined as clinical T3 with extramural tumour invasion >5 mm or T4) and treated with resection with a curative intent between 2015 and 2019. Propensity score matching (PSM) in a 1:1 ratio was performed to compare short‐term surgical and oncological outcomes in patients receiving NCT with patients operated on without receiving NCT.ResultsA total of 179 LACC patients were treated with NCT and 1131 were not. After PSM, 145 patients remained in each group. We found no significant differences in any short‐term postoperative outcomes between the two groups. We found significant differences in favour of NCT regarding radicality and pathological N category [86% vs. 81% R0 (P = 0.029) and 51% vs. 46% pN0 (P = 0.017), respectively].ConclusionNeoadjuvant chemotherapy for LACC does not result in worse short‐term postoperative outcomes and may increase the R0 rate as well as node‐negative disease. Results on long‐term benefits including survival are awaited from several ongoing randomized controlled trials.
The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study
Authors:   COVIDSurg Collaborative
Published: March 2022

AbstractAimThe SARS‐CoV‐2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non‐delayed surgery.MethodsThis was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January–April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin.ResultsOverall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90–1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69–1.27, P = 0.672). Longer delays were not associated with poorer outcomes.ConclusionOne in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID‐19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long‐term survival attributable to delays is likely to be due to micro‐metastatic disease.
Impact assessments of wind farms on seabird populations that overlook existing drivers of demographic change should be treated with caution
Authors: Horswill Catharine , Miller Julie A. O. , Wood Matt J. 
Published: March 2022

AbstractPopulation viability analyses (PVA) are now routinely used during the consenting process for offshore wind energy developments to assess potential impacts to vulnerable species, such as seabirds. These models are typically based on mean vital rates, such as survival and fecundity, with some level of environmental stochasticity (i.e., temporal variation). However, many species of seabird are experiencing population decline due to temporal (i.e., directional) trends in their vital rates. We assess the prevalence of temporal trends in rates of fecundity for a sentinel species of seabird, the black‐legged kittiwake Rissa tridactyla, and examine how accounting for these relationships affects the predictive accuracy of PVA, as well as the projected population response to an extrinsic threat. We found that temporal trends in kittiwake rates of fecundity are widespread, and that including these trends in PVA assessments dramatically influences the projected rate of population decline. We advocate that model validation become a prerequisite step in seabird PVA assessments to identify potential biases influencing the projected population response. We also argue that environmental factors driving current population dynamics need to be incorporated in PVA impact assessments as potential “worst‐case” scenarios. These findings have immediate application for improving and reducing uncertainty in impact assessments conducted as part of the consenting process for offshore wind energy developments.
Impacts of fiscal decentralization on local development in Vietnam: A disaggregated analysis
Authors: Bui Manh‐Tien , Le Thai‐Ha , Park Donghyun 
Published: March 2022

AbstractAfter the Doi Moi reforms, Vietnam pursued fiscal decentralization to strengthen the autonomy and governance capacity of local governments. While several empirical studies analysed the impact of fiscal decentralization on the economic growth of Vietnamese provinces, very few studies examined its impact on their social development. This study represents an initial effort to fill this gap. The empirical analysis applied the panel corrected standard errors (PCSE) estimation and stochastic frontier analysis (SFA) to an updated panel data of 63 Vietnamese provinces, spanning the period from 2011 to 2019. The results indicate a positive impact of fiscal decentralization on both economic and social development as well as efficiency of resource utilization for development targets. However, realizing the full potential of fiscal decentralization requires the fulfilment of certain conditions.

AbstractObjectivesBoth peripherally inserted central catheters (PICCs) and implanted port catheters (PORTs) are commonly used for the delivery of immunochemotherapy. We compared the safety of the two types of devices in a homogeneous and monocentric population of diffuse large B‐cell lymphoma (DLBCL) patients who were treated with first‐line immunochemotherapy by evaluating the numbers of catheter‐related venous thromboses (VTs) and infections that occurred in the six months after implantation according to the type of device.MethodsUsing a propensity score, the adjusted relative risk (ARR) between the type of catheter and the occurrence of catheter‐related complications (infection and/or VT) of interest was retrospectively determined.Results479 patients were enrolled (266 PORTs/213 PICCs), and 26 VTs (5.4%) and 30 infections (6.3%) were identified in the period following PICC/PORT implantation. The adjusted relative risk (ARR) of catheter‐related complications (infection and/or VT) according to the type of device was 2.6 (95% CI =1.3–5.9, p = .0075). This risk increase associated with the PICC device was significant for both infections (ARR = 3.2; 95% CI = 1.3–10.9) and thrombosis (ARR = 4; 95% CI = 1.5–11.6).ConclusionOur study supports the preferential use of PORTs for the first line of treatment for DLBCL patients.

AbstractDespite intensive research on species dissimilarity patterns across communities (i.e. β‐diversity), we still know little about their implications for variation in food‐web structures. Our analyses of 50 lake and 48 forest soil communities show that, while species dissimilarity depends on environmental and spatial gradients, these effects are only weakly propagated to the networks. Moreover, our results show that species and food‐web dissimilarities are consistently correlated, but that much of the variation in food‐web structure across spatial, environmental, and species gradients remains unexplained. Novel food‐web assembly models demonstrate the importance of biotic filtering during community assembly by (1) the availability of resources and (2) limiting similarity in species’ interactions to avoid strong niche overlap and thus competitive exclusion. This reveals a strong signature of biotic filtering processes during local community assembly, which constrains the variability in structural food‐web patterns across local communities despite substantial turnover in species composition.
