Inflammatory Bowel Diseases and Coexisting Spondyloarthritis: A Neglected and too Often Under-Reported Association by Radiologists. A Multicenter Study by Italian Research Group of Imaging in Rheumatology

Purpose: The purpose of this study was to evaluate the prevalence and the underreporting rate of sacroiliitis (SI) in a large cohort of patients with biopsy-proved Crohn’s disease (CD) who underwent magnetic resonance enterography (MRE) or computed tomography enterography (CTE). Materials and Methods: Patients with CD were recruited from eight Italian health centers in the period from January 2013 to December 2017. Disease activity was recorded according to the CD activity index (CDAI). The scans were read by two blinded readers who defined the presence of SI according to Assessment of SpondyloArthritis International Society (ASAS) classifications and European League Against Rheumatism (EULAR) recommendations. Moreover, SI was scored using a simplified Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system. Results: Interobserver agreement in diagnosing SI on imaging was good (K = 0.72–0.83). SI was diagnosed in 129 (14.4%, 54 men, 75 women) out of 894 patients; however, sacroiliac joint (SIJ) abnormalities were not mentioned in the radiological reports of 112 patients (86%). Fifty (38.7%) out of 129 patients also underwent a subsequent SIJ evaluation through a dedicated MRI protocol to confirm SI. SI was found in a higher percentage of patients with “active” than “inactive” CD (18% vs. 4%). Conclusion: This study confirms the feasibility of CTE and MRE for the screening of SI in CD patients; however, it also underlines the remarkable problem concerning the underreporting of this entity in radiological practice.
Linking Perceived Organizational Support, Affective Commitment, and Knowledge Sharing with Prosocial Organizational Behavior of Altruism and Civic Virtue

The study of prosocial organizational behaviors has been receiving increasing attention, due to their relevant contribution to sustainable organizational and personal development. This research proposes and tests a model that tackles the factors that drive two unrewarding extra-role behaviors of individual or organizational citizenship, altruism, and civic virtue, and assesses multiple mediation relationships. The sample data are derived from a questionnaire survey of 1350 Spanish workers and were analyzed using partial least squares structural equations modelling. Research findings reflect the mediating role of knowledge sharing behavior in the relationship between affective commitment and altruism. Moreover, a significant relationship was found between affective commitment and civic virtue, which is stronger under the mediating role of knowledge sharing behavior. Finally, affective commitment plays a mediating role in the relationship between perceived organizational support and knowledge sharing behavior. Implications for sustainable human resource management, practical interventions, and future research recommendations are provided.
Understanding vulnerability and resilience in Somalia

In the recent years, Somalia witnessed a heightened frequency of droughts and conflicts. This article explores the experiences of Somalis during the 2011 and 2016 crises, examining the link between vulnerability and resilience, and the role played by international humanitarian responders in resilience building. The aim of this study is to provide information on how different population groups responded to and managed to survive recurrent shocks; the prevailing drivers of marginalisation and exclusion, and mechanisms through which these are maintained; and the role of external stakeholders. A review of literature was combined with field consultations in four study sites: Kismayo Urban, Kismayo Rural, Baidoa and Beledweyne, and complemented by consultations with the Somali diaspora community in Kampala, Uganda. Participatory research methods were used, including participant observation, focus group discussions, household dialogues, livelihood analysis, well-being analysis and gender analysis. The findings of the study revealed an inextricable link between vulnerability, conflict and disasters, with the major challenge facing the most vulnerable Somalis being uncertain about the future. Somali households adopted different coping strategies depending on their resource endowments, including the social and organisational coping strategies, divesting of non-essential domestic assets, and diversification of income generation and food production strategies. Thus, different population groups survived the shocks through social connectedness, which aligned with the effective use of remittances to create robust mechanisms for sharing risk. That notwithstanding, groups that had the backing of more powerful clans seemed to have the edge over those who did not.
Relationship of surface soil moisture with solar-induced chlorophyll fluorescence and normalized difference vegetation index in different phenological stages: a case study of Northeast China

Solar-induced chlorophyll fluorescence (SIF) is closely related to vegetation photosynthesis, and is considered as a direct and non-invasive indicator of the functional status of photosynthetic machinery; the normalized difference vegetation index (NDVI) can also reflect photosynthetic characteristics. Both are related to surface soil moisture (SSM), which is susceptible to drought, and phenology plays an important role in these vegetation-moisture relationships. Based on a variety of gridded SIF, NDVI, and SSM datasets obtained from satellite sensors, we presented the detailed relationships of SSM with SIF and NDVI in different phenological stages. Results showed that SIF and NDVI were significantly correlated with SSM in different phenological stages, especially during the maturity and senescence stages. For different vegetation types, SIF was more sensitive than NDVI to SSM anomalies in grasslands and forests during the maturity stage and rainfed croplands during the senescence stage. These relationships were regulated by precipitation and mean temperature, and decreased precipitation had the most significant impact when accompanied by increased temperature during the maturity stage or decreased temperature during the senescence stage. Our findings shed light on the role that phenology has in the relationships of SSM with SIF and NDVI on a large scale, which can further improve the understanding of vegetation-moisture relationships.
A Potential Application of Infrared Thermography (IRT) in Mediterranean Lactating Buffalo

Skin temperature is an important indicator of the physical and healthy status of animals. Infrared thermography (IRT) leads itself to countless applications in biology thanks to its characteristics of versatility and high sensitivity. Contactless surface temperature measurement using infrared thermography is a modern, noninvasive and safe technique of thermal profile visualization. IRT has also been used on humans and animals as a non-invasive diagnostic method for measuring physiological or pathological changes in skin temperature. The aim of this study was to investigate the possibilities of using IRT to assess the temperatures of the udder in order to a possible early diagnosis of mastitis in lactating buffalo. For the achievement of broached objectives, the measurements were carried out in a zootechnical farm located in Southern Italy. The number of lactating buffalo cows engaged in the udder experiment was 192. A FLIR i7 thermal imaging scanner was used for obtaining thermal images. Milk samples were taken on the same day as thermographic measurements after capturing thermal images. The PROCMEANS procedure was used to obtain the descriptive statistics for SCC and temperature in all category. The correlation between temperature and different categories of SCC was significantly positive. The relationship between SCC and temperature was indicated by an exponential equation [y = 35.77 (0.00024 * x)]; R2 = 0.640; <0.001]. The results suggested that thermography can be used for early detection of subclinical mastitis in buffalo.
Group Threat, Same-Sex Marriage, and Hate Crime Based on Sexual Orientation

Abstract Prior research has begun the task of assessing the applicability of group threat theory to explain sexual orientation hate crime. Drawing upon this perspective, researchers have hypothesized that relatively large and growing gay populations might be perceived as a threat to heterosexual norms, leading to sexual orientation hate crimes. Previous work has also identified an additional source of threat that may be particularly salient: threat to traditional marriage. Using data for a sample of metropolitan areas, we assess the impact of a previously unexamined potential source of threat: same-sex marriage. We also compare the relationships between the relative size and growth of the gay population and hate crimes expressed as incidence and victimization rates. The results reveal that the effects of the gay population’s relative size on incidence vs. victimization rates differ in important respects, and that the level of same-sex marriage is positively associated with both hate crime rates.
Two-Steps Slotting Method in Magnet Edge of PMG for Wind Energy Harvesting

This paper focuses on the study of how to decrease the value of the cogging torque in an Inset Permanen Magnet Generator. The permanent-magnet generator of an integral slot number with 24 slots and 8 poles was selected and investigated for the purposes of this study. The cogging torque of the permanent-magnet generator can be minimized by combining two slottings in the magnet edge with a gradually inclined surface end. The electromagnetic simulations and analysis of the permanent-magnet generator studied were performed using numerical analysis by means of FEMM 4.2. To obtain a faster computation, FEMM 4.2 was combined with LUA 4.0 programming. Using FEMM 4.2, it was found that by applying two-step slotting in the magnet edge combined with a gradually inclined surface end, the cogging torque of the permanent-magnet generator selected can effectively reduce the cogging torque of the machine by approximately 98.14% compared against the initial magnet model. It can be concluded that the integration of the two-step slotting in the magnet edge and the gradually inclined surface end can effectively reduce the cogging torque of the permanent-magnet generator machine. Furthermore, decreases in the density of the magnetic flux in the core of the permanent-magnet generator can also be found.
Employee proactive goal regulation and job performance: The role modeling and interacting effects of leader proactive goal regulation

Given the critical role of leaders in managing employees’ goal-setting, we theorized and examined how leader proactive goal regulation facilitates employee proactive goal processes and outcomes. Based on a sample of 74 leaders and 371 employees who work in research and development groups, we found that employees’ three motivational states—role breadth self-efficacy, psychological ownership, and activated positive affect—were positively associated with job performance via employee proactive goal regulation. In addition, the effects of leader proactive goal regulation on this mediation model were twofold. First, there was a direct effect on employee proactive goal regulation, which, in turn, positively related to job performance. Second, there was a moderating effect of leader proactive goal regulation such that employees delivered high job performance when their leaders were high in proactive goal regulation, regardless of employees’ own levels of proactive goal regulation. This study highlights the importance of not only employee but also leader proactive goal regulation in connecting employees’ proactive motivational states with job performance.
Deriving Mobility Service Policy Issues Based on Text Mining: A Case Study of Gyeonggi Province in South Korea

Mobility services facilitate various tasks related to transportation and passenger movements. Because of the Fourth Industrial Revolution, the importance of mobility services has been recognized by many countries. Thus, research is ongoing to provide more convenience to passengers and to obtain more efficient transportation systems. In the Republic of Korea, the officials of Gyeonggi Province are interested in providing an advanced mobility service to its residents; however, they still do not have any specific or detailed policies. This study aimed at deriving the key issues facing mobility services, especially in the case of Gyeonggi Province, by using a text mining technique and a clustering algorithm. First, a survey was taken by traffic and urban experts to collect reasonable plans for Gyeonggi-Province-type mobility service, and a morpheme analysis was then used for text mining. Second, the results reveal that the term frequency–inverse document frequency (TF-IDF) algorithm has better performance than frequency analysis. Third, the K-means application results in six clusters and six mobility service policy issues were determined by combining the words in each cluster. Finally, the methodology confirmed the validity and effectiveness of the proposed method by showing that the results reflect the current situation in the province.
Establishing Core Factors of Risk Management Influencing Performance Outcome of Small and Medium Firm's Construction Projects in Gauteng

The quest for delivering successful construction projects has urged South African small and medium enterprises (SMEs) to adopt risk management in their projects. However, it has been evinced that SMEs projects in South Africa especially in the Gauteng province have encountered poor performances. Thus, this article determines core risk management factors influencing project outcome of SMEs. A deductive approach was embraced using a questionnaire. The data were collected from 181 conveniently sampled respondents in Gauteng, graded from Grade 1 to 6 of the CIDB (Construction Industry Development Board) grading system. The Statistical Package for the Social Science (SPSS) version 23 was used to analyse the data by computing exploratory factor analysis and multiple regression analysis. It was revealed that SMEs performance outcome is influenced by eight risk management factors. The influential factors are organisational environment, defining project objectives, resource requirements, risk measurement, risk identification, risk assessment, risk response and action planning and monitoring, review and continuous improvement. The risk management factors established in this article are reliable and valid in projects undertaken by SMEs in the South African construction industry and the findings can serve as a guideline for contractors to achieve success in this context. The study may be repeated in other countries globally, however, it cannot be generalised due to the restrictions pertaining to the geographical area.
A draft framework for quality management system auditor education: findings from the initial stage of a Delphi study

PurposeChanges in structure and conceptual underpinnings of ISO 9001 mean that quality management system (QMS) auditors require a wide knowledge base and skill set to effectively evaluate contemporary QMS and add value to the process. Hence, this study presents an open curriculum framework of the knowledge, skills and attributes for quality auditor education.Design/methodology/approachThis study describes the first two phases of a three-phase study examining the educational requirements for external quality auditors (EQAs). Phase 1 involved a review of relevant international literature on auditor competence and education; Phase 2 involved the collection of qualitative data from a panel of experts, combined with the initial round of a Delphi study. A thematic analysis was used to analyze the findings from the questionnaire.FindingsThe findings of this study suggests there is a need to improve EQAs education, as most experts reported the quality of audit to be variable, inconsistent, poor and diminishing in value. The most important improvements to auditor education are to update and improve the auditors' knowledge on the requirements of the ISO 9001 standard and technology in business and skills such as report writing, communication, IT understanding and analytical ability. Some of the attributes reported as being desirable to instill in EQAs include the following: objectivity, integrity, ethics and professionalism; being observant, perceptive, articulate and confident; having good judgment; flexibility, adaptivity and diplomacy, fairness and open-mindedness.Originality/valueThis study highlights the need for wider EQA education based on the gap identified in its performance. The resulting framework can be adopted by accreditation and certification bodies to evaluate and improve their auditors' audit performance.
Isolation by environment and recurrent gene flow shaped the evolutionary history of a continentally distributed Neotropical treefrog

Phylogeographic studies show how historical and current changes in landscapes shape the geographic distribution of genetic diversity in species of animals and plants. In particular, for the species of the Diagonal of Open Formations (DOF), the compartmentalization of the Central Brazilian Plateau (CBP) during the Tertiary and climatic oscillations during the Quaternary have often been invoked to explain the origin and current patterns of biodiversity. We investigated how landscape changes and climatic oscillations shaped the distribution and diversification history of a widespread South American treefrog.
The Economic Impact of Lockdowns: A Persistent Inoperability Input-Output Approach

The COVID-19 pandemic has forced governments around the world to implement unprecedented lockdowns, mandating businesses to shut down for extended periods of time. Previous studies have modeled the impact of disruptions to the economy at static and dynamic settings. This study develops a model to fulfil the need to account for the sustained disruption resulting from the extended shutdown of business operations. Using a persistent inoperability input-output model (PIIM), we are able to show that (1) sectors that suffer higher levels of inoperability during quarantine period may recover faster depending on their resilience; (2) initially unaffected sectors can suffer inoperability levels higher than directly affected sectors over time; (3) the economic impact on other regions not under lockdown is also significant.
Parsimonious Model for Assessing Nutrient Impacts on Periphyton-Dominated Streams

AbstractThe following paper illustrates how parsimonious process–based models can be used to assess the impact of nutrients on shallow periphyton-dominated streams. After a brief overview of previous research, a simple model is developed to predict periphyton levels below a point nutrient loading to a uniform geometry, steady-state stream. The model is then used to address two eutrophication management questions. First, it is shown how simple models can be employed for nutrient loading calculations, that is, to determine the nutrient loadings necessary to maintain periphyton below nuisance levels downstream of a point source. Then, it is shown how the model can be used to establish nutrient criteria is illustrated, that is, to directly calculate the required in-stream nutrient concentrations to achieve the same objective.
Outcome of atypical haemolytic uraemic syndrome relapse after eculizumab withdrawal

Abstract Background The introduction of eculizumab has significantly improved the outcome of patients with atypical haemolytic uraemic syndrome (aHUS). Because of the risk of relapse after discontinuation, eculizumab was proposed as life-long therapy. However, data on the outcome of relapse are limited. In the Netherlands, patients with aHUS are treated with a restrictive eculizumab regime and are included in a national observational study (CUREiHUS, Dutch Trial Register NTR5988/NL5833). Methods For this interim safety analysis, we evaluated the outcome of all adult patients with a suspected relapse, defined as the need to intensify eculizumab after tapering or withdrawal of therapy. Results We describe 11 patients who received renewed eculizumab therapy because of suspected relapse. In three patients with aHUS in native kidneys, estimated glomerular filtration rate (eGFR) returned to baseline value and remained stable without overt proteinuria after follow-up. Six out of eight transplanted patients responded to eculizumab therapy with improvement in eGFR. After a median follow-up of 24.6 months, a reduction of eGFR ≥25% was observed in three of these transplanted patients, which was attributed to the aHUS relapse in only one patient. Conclusions This interim analysis suggests that re-treatment with eculizumab after relapse is safe and feasible. We will continue to use our restrictive treatment strategy.
Potential Sources of Particulate Iron in Surface and Deep Waters of the Terra Nova Bay (Ross Sea, Antarctica)

The distribution of particulate Fe (pFe), suspended particulate matter (SPM), and other particulate trace metals were investigated in Terra Nova Bay as part of CDW Effects on glaciaL mElting and on Bulk of Fe in the Western Ross sea (CELEBeR) and Plankton biodiversity and functioning of the Ross Sea ecosystems in a changing Southern Ocean (P-ROSE) projects. Variable concentrations of SPM (0.09–97 mg L−1), pFe (0.51–8.70 nM) and other trace metals were found in the Antarctic Surface waters (AASW) layer, where the addition of meltwater contributed to the pool with both lithogenic and biogenic forms. The deeper layer of the water column was occupied by High Salinity Shelf Water (HSSW) and Terra Nova Bay Ice Shelf Water (TISW) encompassing glacial water as confirmed by the lightest δ18O measured values. The concentration of pFe in TISW (11.7 ± 9.2 nM) was higher than in HSSW samples (5.55 ± 4.43 nM), suggesting that the drainage of material released from glaciers surrounding the area is relevant in terms of pFe contribution. Particulate Fe/Al and Mn/Al ratios were substantially in excess compared with the mean crustal ratios. Microscopic analyses confirmed that more labile Fe oxyhydroxides and authigenic MnO2 phases were present together with biogenic sinking material. Future expected increasing melt rates of these glaciers enlarge Fe input, thus having a greater role in supplying iron and counteracting the reductions in sea ice cover around Terra Nova Bay.
A scheme of semi-micro analysis for the major elements in clay minerals, based on modifications to conventional methods of silicate analysis

A scheme is presented for the semi-micro analysis for the major elements in clay minerals, based mainly on improvements to conventional colorimetric methods. Silica and alumina are determined after fusing a 50-mg sample with sodium hydroxide. Titanium, total iron, calcium, magnesium, phosphorus and manganese are determined colorimetrically on a hydrofluoric-sulphuric acid digest of a 50-mg sample; sodium and potassium are determined flame photometrically on the same digest. Ferrous iron is determined separately. Additional methods for the determination of total water, total sulphur and fluorine are indicated.
