Are University Rankings Statistically Significant? A Comparison among Chinese Universities and with the USA
Authors: Leydesdorff Loet , Wagner Caroline S. , Zhang Lin 
Published: March 2021

Abstract

Purpose
Building on Leydesdorff, Bornmann, and Mingers (2019), we elaborate the differences between Tsinghua and Zhejiang University as an empirical example. We address the question of whether differences are statistically significant in the rankings of Chinese universities. We propose methods for measuring statistical significance among different universities within or among countries.

Design/methodology/approach
Based on z-testing and overlapping confidence intervals, and using data about 205 Chinese universities included in the Leiden Rankings 2020, we argue that three main groups of Chinese research universities can be distinguished (low, middle, and high).

Findings
When the sample of 205 Chinese universities is merged with the 197 US universities included in Leiden Rankings 2020, the results similarly indicate three main groups: low, middle, and high. Using this data (Leiden Rankings and Web of Science), the z-scores of the Chinese universities are significantly below those of the US universities albeit with some overlap.

Research limitations
We show empirically that differences in ranking may be due to changes in the data, the models, or the modeling effects on the data. The scientometric groupings are not always stable when we use different methods.

Practical implications
Differences among universities can be tested for their statistical significance. The statistics relativize the values of decimals in the rankings. One can operate with a scheme of low/middle/high in policy debates and leave the more fine-grained rankings of individual universities to operational management and local settings.

Originality/value
In the discussion about the rankings of universities, the question of whether differences are statistically significant, has, in our opinion, insufficiently been addressed in research evaluations.
Microbiological safety of food of animal origin from organic farms
Authors: Sosnowski Maciej , Osek Jacek 
Published: March 2021

Abstract
The organic food sector and consumer interest in organic products are growing continuously. The safety and quality of such products must be at least equal to those of conventional equivalents, but attaining the same standards requires overcoming a particular problem identified in organic food production systems: the occurrence of bacterial pathogens such as Salmonella, Campylobacter, Listeria monocytogenes, Staphylococcus aureus and pathogenic Escherichia coli. These food-borne microorganisms were detected in the production environments of such food. The prevalence of pathogenic bacteria in organic livestock and products may be higher, but may also be the same as or lower than in like material from conventional farms. Furthermore, the incidence of antimicrobial-resistant bacteria was more often detected in conventional than in organic production. The aim of this review was to present the recent information on the microbiological safety of food of animal origin produced from raw materials from organic farms.
Peak Plantar Pressure as a Risk Factor for Lower Extremity Overuse Injury Among Infantry Soldiers
Authors: Ņesteroviča Darja , Stepens Ainārs , Vaivads Normunds 
Published: March 2021

Abstract
The majority of reported injuries among military populations are injuries due to cumulative repetitive microtrauma — overuse injuries. Plantar pressure measurement is a simple tool to analyse lower limb biomechanics through the assessment of forces applied to the foot. This study aimed to determine the relation between peak plantar pressure and lower extremity overuse. Sixty-six active-duty infantry male soldiers, with mean age 29.7 years (range 22–40 years), and mean service time 5.2 years (range 1–15 years) participated. The highest peak plantar pressure (PPP) at the forefoot occurred at the hallux (cases: 50.82 n/cm2, SD = 38.84; control: 34.39 n/cm2, SD= 28.03) and 3rd metatarsal head (cases: 54.40 n/cm2, SD = 33.83; control: 49.16 n/cm2, SD=28.87). The study demonstrated elevated PPP among cases. Statistically significant results were found at the hallux (χ2(1) = 6.8; p = 0.01), medial heel (χ2(1) = 5.18; p = 0.02) and lateral heel (χ2(1) = 12.12; p < 0.01) regions. The results show that plantar pressure assessment could be used as a useful screening tool for early lower extremity overuse injury detection.

Published: March 2021

Abstract
The following study is aimed at investigating the construct validity of the 25-item Connor-Davidson Resilience Scale (CD-RISC 25) on a Romanian military population. The exploratory factor analysis was conducted on 434 male military participants, aged between 24 and 50 years (M = 34.83, S.D. = 6.14) and the confirmatory factor analysis was conducted on a sample of 679 military participants, of 605 men and 74 women, aged between 18 and 59 years (M = 38.37, S.D. = 9.07). Factor analysis of the scale showed it to be a bidimensional, rather than a multidimensional instrument, as the original five-factor structure was not replicated in this military Romanian sample. Moreover, EFAs suggested that a 14-item bidimensional model should be retained and CFA confirmed that this model fit the data best.
Sustainable Maritime Fleet Management in the Context of Global Sulphur Cap 2020
Authors: Atari Sina 
Published: March 2021

Abstract
Since the implementation of Emission Control Areas (ECA) in 2015, investment decisions related to abatement technologies represent a crucial task in the maritime industry. Currently, the focus in the maritime sector is on Sulphur reductions due to SECA regulations and the legislative of Global Sulphur Cap that started in 2020. A special challenge appears in maritime fleet management where sets of ships have to be considered, representing portfolios of assets that have to be equipped with a variety of different options of abatement technologies.
Modern portfolio theory has been applied to various economic decisions to achieve an optimal allocation of resources among different investment opportunities. The research investigates and discusses the application of the Markowitz´ optimization in the context of SECA regulations for maritime fleets. The optimal investment portfolios are taking into account the three most important compliance options based on the use of low Sulphur fuel, the use of LNG fuel and the use of HFO with a scrubber. The theoretical results are empirically validated by a case of a shipping line operating 10 vessels.

Background:There are limited data regarding the difference in progression pattern between acral melanoma and nonacral melanoma.Aims:The objectives of this study were to compare the progression pattern between acral and nonacral melanoma and evaluate its impact on clinical outcomes.Methods:Clinical and histopathological features, survival outcomes and prognostic factors of 492 patients with acral melanoma or nonacral melanoma were retrospectively evaluated using the Asan Medical Center database.Results:The male-to-female ratio and the mean age was 1:0.92 and 60.2 years for acral melanoma (n= 249), and 1:0.85 and 58.4 years for nonacral melanoma (n= 243), respectively. The demographic difference was not significant. Although prediagnosis duration was longer and the advanced stage was more common in acral melanoma than that in nonacral melanoma, the vertical growth phase was more common in nonacral melanoma than that in acral melanoma, whereas, the horizontal diameter is longer in acral melanoma than that in nonacral melanoma. Dissemination to lymph nodes was more common in acral melanoma than that in nonacral melanoma. Lymph node involvement was associated with deeper Breslow thickness in nonacral melanoma but not in acral melanoma. The degree of correlation of prediagnosis duration with horizontal diameter was remarkable in acral melanoma, but with Breslow thickness in nonacral melanoma. Overall survival was worse in acral melanoma than that in nonacral melanoma. The prognostic value of Breslow thickness was more remarkable in nonacral melanoma than that in acral melanoma.Limitations:This study is a retrospective, single-center design.Conclusion:Acral melanoma has a longer radial growth phase compared with nonacral melanoma. However, acral melanoma is commonly associated with lymph node dissemination which contributed to worse survival in acral melanoma than nonacral melanoma.
Gestion de l’immigration clandestine : la puissance normative de l’Union européenne à la dérive ?
Authors: Albessard Guillaume 
Published: March 2021

L’immigration clandestine ne cesse d’alimenter les débats nationaux et européens. A travers cet article, la gestion européenne des phénomènes migratoires est mise en relation avec l’attachement historique à la norme et au soft power émanant de l’Union européenne. L’hypothèse principale consiste à affirmer que cette gestion représente une rupture avec le pouvoir normatif européen. Le poids des intérêts nationaux et l’approche intergouvernementale permettent d’abord de mettre au jour une vision « insécurisante » de l’immigration. Par ailleurs, le processus d’externalisation des frontières remet en cause l’attachement manifeste à la liberté et la sécurité. Quant à Frontex, son rôle semble paradoxal au regard des principes de bonne gouvernance et de rejet de la « norme », au profit de la force. Enfin, l’idée d’ « Europe forteresse » désignerait moins les effets de la politique migratoire européenne que ses intentions.

Hyperlipidemia is a prevalent global health problem, and it is linked to various cardiovascular disorders. The side effects of the current lipid-lowering drugs have increased the tendency to move toward traditional and alternative remedies. The study aims to Formulate and evaluate the Antilipidemic activity of Polyherbal formulations used as a traditional medicine in the Malabar area, Kerala by in vitro and in vivo methods. Further, the present study also compares the impact of seasonal variations on chemical contents of ingredient herbs of polyherbal medicine. They were analyzed for, anti-oxidant activity by DPPH and Nitric oxide method and In-vitro anti-cholesterol activity by cholesterol enzymatic endpoint method using simavastatin as a positive control. The formulation showing highest anti-oxidant and in- vitro Antilipidemic activity was selected for in-vivo analysis. Out of four formulations, PHF 1 shows low IC50 values in DPPH and Nitric oxide methods (250.45± 0.60, 985.40±5.59), respectively. The in-vitro anti-cholesterol activity showed a maximum % of inhibition for PHF1. Based on this PHF 1was selected for in vivo analysis. Acute toxicity was performed according to OECD guidelines. The antilipidemic activity was conducted by Diet-induced hyperlipidemia model in Wistar albino rats, containing six animals in each group. All the groups except saline control received a high-fat diet for two weeks. The Polyherbal formulation (200 mg/kg & 400 mg/kg) showed significant (P<0.05) reduction in total serum cholesterol and lipid levels compared to the vehicle control group. This present study proved that Polyherbal formulation has Antilipidemic activity against the diet-induced hyperlipidemia model by reducing the total serum cholesterol (TC), triglycerides (TG), very low-density lipid (VLDL), low-density lipids(LDL) levels and increasing high-density lipid (HDL) level.

Preventing medication error is done by upgrading the drugs administrators knowledge at the Community Health Center in handling the high alert drugs. One of the possibility is by training. This research is conducted to understand the influence of training toward the suitability of high alert drugs storage. This research constitutes quasi-experimental design with pre and post-analysis approach along with by using a control group as a comparison. The population of research consists of all of community health centre drugs administrators in Ogan Komering Ilir Regency and Mataram City. The sample of research are the drugs administrators, Human Resources, who work at the Community health centre of Ogan Komering Ilir and Mataram city were chosen to use non-probability sample. The intervention was conducted toward the drugs administrators with the material that has been standardized by the Ministry of Health of the Republic of Indonesia. The instrument is in the form of List of Visit that has been validated to assess the suitability of high alert drugs storage at Community health centre by using SPSS-23 with Wilcoxon Signed Rank and Mann-Whitney U tests. The result of the research shows that the majority of the Intervention group of Community health centre (83,33%) the storage of high alert drugs is appropriate with the standard after training. The percentage difference of the appropriate high alert drugs storage test between intervention group and control group after the training (p<0,05). This study concludes that the training that was conducted toward the drugs administrators can increase the percentage of high alert drugs suitable storage that lead to the decreasing of medication error incidents at Community health centre.
