Can the law fix the problems of fashion? An empirical study on social norms and imbalance of power in the fashion industry
Authors: Noto La Diega Guido
Published: April 2020

The fashion industry is affected by an imbalance of power that goes beyond the outsourcing of part of the manufacture to developing countries. Said imbalance characterises the whole supply chain and hinders freedom of expression, freedom to conduct business and, hence, creativity and innovation. In order to understand fashion, IP lawyers and lawmakers need to take into account that the law is not the main device the regulating the relevant relationships. Indeed, fashion is a closed community, a family where complaining is rather frowned upon and where contracts do not reflect the actual relationships between the parties. In order to rebalance power, this article explores the possibility to treat good faith and inequality of bargaining power as unifying principles of contract law. However, in light of the evidence collected during a number of in-depth interviews with fashion stakeholders, it seems clear that social norms are the main source of regulation of relationships and, therefore, intervening at the level of the contracts may not be helpful. Competition law, in turn, may be of more help in rebalancing power; however, cases such as Coty v Parfümerie Akzente do not augur well. Moreover, competition law is useful when the relationship is over, but it is in all the stakeholders’ interest to keep the relationship alive while fixing its imbalance. This study confirms recent findings that social norms do not only have a positive impact on fields with low IP-equilibrium and it sheds light on the broader consequences of the reliance on social norms and on its relationship to power imbalance. This work makes a twofold recommendation. First, IP lawyers should engage more with the unfamiliar field of social norms. Second, advocates of a reform of IP aimed at transforming the industry in an IP-intensive one should be mindful that the effort may prove useless, in light of the role of social norms, especially if power is not distributed.

Published: April 2020

University Libraries play a crucial role in moving towards Open Science, contributing to more transparent, reproducible and reusable research. The Center for Digital Scholarship (CDS) at Leiden University (LU) library is a scholarly lab that promotes open science literacy among Leiden’s scholars by two complementary strategies: existing top-down structures are used to provide training and services, while bottom-up initiatives from the research community are actively supported by offering the CDS’s expertise and facilities. An example of how bottom-up initiatives can blossom with the help of library structures such as the CDS is ReproHack. ReproHack – a reproducibility hackathon – is a grass-root initiative by young scholars with the goal of improving research reproducibility in three ways. First, hackathon attendees learn about reproducibility tools and challenges by reproducing published results and providing feedback to authors on their attempt. Second, authors can nominate their work and receive feedback on their reproducibility efforts. Third, the collaborative atmosphere helps building a community interested in making their own research reproducible. A first ReproHack in the Netherlands took place on November 30th, 2019, co-organised by the CDS at the LU Library with 44 participants from the fields of psychology, engineering, biomedicine, and computer science. For 19 papers, 24 feedback forms were returned and five papers were reported as successfully reproduced. Besides the researchers’ learning experience, the event led to recommendations on how to enhance research reproducibility. The ReproHack format therefore provides an opportunity for libraries to improve scientific reproducibility through community engagement.

In late 2019, SARS-CoV-2, a new coronavirus causing COVID-19, emerged in Wuhan (China). As of April 13 2020 it has caused 1.807.308 infections and 119.410 deaths worldwide. Due to the way this virus is transmitted and considering gastroenterology and digestive endoscopy services are a source of easy dissemination given the constant exposure with aerosols that are emitted during procedures there is an increased risk for both health care professionals and patients undergoing endoscopy. It is of great importance to establish prevention tools within the gastroenterology and digestive endoscopy services, based on the evidence gathered to date and recognizing that we are in a constant search for measures to reduce risk of infection that will provide a safe environment to staff and patients. Pubmed database was searched for the following terms: (“COVID-19” OR “coronavirus” OR “SARS-Cov-2”) and (“gastrointestinal” OR “transmission” OR “intestinal” OR “digestive” OR “endoscopy” OR “esophagogastroduodenoscopy” OR “colonoscopy”). Therefore, all patients brought in to undergo endoscopic procedures should be considered high-risk and current prevention tools will be made known worldwide.

The present article concerns with the modern state of things of the conflict resolution specialists’ training in the US universities. The analysis is based on the informational and promotional materials which were picked up from the 11 American universities’ websites. The aim of the analysis was the examination of the four sections, which are: the orientation of the academic program, the content of the program or the scope of the skills, the main methodology of the academic program and the educational technologies. Together with the analysis of the US universities’ academic programs the article provides the comparative analysis of these programs with the Russian academic programs. On the back of this comparative analysis the authors come to the comprehensive conclusion according to which the specialists’ training in the field of the conflict resolution and peacebuilding in the US does not have significant differences from Russian ones and is carried out within one international academic trend in regard to its main features which are: the orientation, content, educational methodology and technologies. The key distinction of the Russian training from the American one is that the Russian academic tradition does have the core subject matter around which the whole academic program is being developed and which is the conflict. This subject matter is being taken in its entirety and the conflict resolution is considered as the closing stage of the conflict studies specialists’ training whereas the academic programs of the US universities embrace the conflict resolution as the subject matter of the academic training and therefores leaves beyond the scope of the training both the theory of the conflict and the forms practice of its manifestation in a number of the programs. The letter is peculiar to both short-term academic programs and the full-time two-year academic programs as it is accepted in the educational space of the Russian Federation. Furthermore, the authors of the article make up the conclusion of the coinciding major educational methodology which guides the academic programs of the American and Russian universities and which is developed on the principles of the interdisciplinarity.

The article analyzes the main problems and prospects for the development of hydrogen energy in shipbuilding. Currently, there is an increase in interest of large companies and government agencies in hydrogen fuel cells (FCs). Two main reasons for this can be distinguished: high fuel cell efficiency (70-80%) and their environmental benefits. But in the near future the mass introduction of technology is unlikely to happen, it is still necessary to solve a number of problems associated with the production and operation of special power plants, and reduce their cost. When technological barriers are overcome, hydrogen energy will reach a new level and, possibly, will be as widespread as traditional or hydropower today.

The purpose of the study was to obtain castings with increased mechanical properties by low-pressure casting using excess pressure on the crystallized casting. The simulation of the process of filling and crystallization of prototypes using the SPH method was carried out. The studies were carried out on a modernized low-pressure injection molding machine model U8261. Prototypes were obtained from AK7ch alloy, special attention is paid to interfacial interaction and intensification of the heat transfer process due to the application of excess pressure. Based on the data obtained, it was found that during crystallization under excessive pressure there is a supercooling effect that reduces the casting solidification time. The use of the SPH method for modeling foundry processes has shown a high level of reliability and requires further development.

Published: April 2020

Objectives: The cornerstone of the management of cervical cancer (CC) traditionally relies on clinical
examination (CE) of tumor size (TS) and local extension of disease. The goal of this study is to determine
the accuracy of CE in comparison to final pathology (FP) in early operable CC.
Methods: This is a multi-center retrospective review of patients with early CC (FIGO 2009 Stage IB1,
IIA1). CE of TS, parametrial invasion (PI), and vaginal involvement (VI) were compared to FP.
Results: The final analysis included 135 patients. Overall, there was a significant difference between CE of
TS compared to FP; mean error of 1.22 cm (p<0.0001). In tumors  2cm the mean error was 1.28 cm
(p<0.0001). No significant discrepancy was observed in tumors <2 cm (mean error: 1.10cm; p=0.5). CE of
TS of endophytic tumors was poor (mean error 1.68cm; p=0.004) compared to exophytic tumors (mean
error: 1.12 cm; p=0.693). There was no significant difference in the identification of VI between CE and FP
(3.7% vs. 8.89%; p=0.067). 14.07% of patients were found to have PI on FP (p<0.0001). There was no
difference in the accuracy CE of TS between non-obese (<30 kg/m2
) and obese patients (30 kg/m2
)
(p=0.061). As a result of FP, 55 patients (40.7%) received adjuvant RT and 38 patients (28.14%) were
upstaged from IB1 to IB2.
Conclusion: CE of TS and PI is inaccurate, especially in tumors  2cm and
Long Term Outcome of Pulmonary Atresia with Major Aorto-Pulmonary Collaterals: Data from a Pooled Analysis
Authors: Ferrero Paolo , Piazza Isabelle , Ciuffreda Matteo , Ferrero Paolo , Sadou Youcef
Published: April 2020

Prognosis of Tetralogy of Fallot and Pulmonary atresia with MAPCAs is variable. We aimed to assess
the outcome of patients who had undergone repair of TOF and PA with MAPCAs by different
institutions and approaches, pooling together data on mortality and reinterventions. Abstracts were
screened and full text papers were examined retrieving data on mortality, reinterventions and
percentage of complete repair. Variables abstracted from the studies were pooled together and
compared among different strategies. 28 papers out of 124 were selected, accounting for 1983
patients. 704 patients had undergone single stage unifocalization, 544 recruitment of PAs, 645
patients multistage and combined approaches. Median follow up was 49 months (36-70). 93 deaths
occurred in the first month (5.4 %): 38 in group one (5.8%), 10 in group 2 (2.3%) and 45 in group 3
(8.6%), p<0.0001. At last follow up a total of 305 deaths occurred (16%) and did not differ among
the three groups: 0.21 (0.15-0.25), 0.18 (0.07-0.26), 0.32 (0,13-0.38) deaths/100patients year,
respectively p=0.43. 465 out of 969 patients, underwent at least one re-intervention (47.9%).
Reintervention rate was similar among the three subsets and inversely correlated with the volume of
institution (r= -0.45, p= 0.04). Although strategies of pulmonary atresia with MAPCAs repair are
based on contrasting philosophies and extreme anatomic varibility, pooling together data from
different studies, outcomes do not differ significantly and are characterized by a high rate of
reinterventions. The latter appears to be significantly influenced by the volume of patients.

Published: April 2020

Neurofibroma, a benign tumor of neural origin, indicates a possible differential diagnosis of adrenal masses
in rare cases. It can be solitary or associated with neurofibromatosis type 1. Neurofibroma in the visceral
compartment is an uncommon location and considered extremely rare. While it has a very low potential for
malignant transformation, accurate diagnosis is nonetheless essential to allow for adequate treatment. In this
article, we report a case of a patient with right-sided abdominal pain, fatigue and B symptoms (night sweats
and weight loss) as a result of an adrenal tumor measuring 12 cm. The tumor was highly suspicious for
malignancy, but the surgical resection revealed a benign neurofibroma. This case report describes a
diagnostic and treatment pathway for nonspecific adrenal lesions.

Published: April 2020

Case: We describe a case of 72-year-old male with dedifferentiated chondrosarcoma with osteosarcomatous
and epithelioid (squamous) dedifferentiation. As first described in the literature by Dahlin and Beabout, a
well-differentiated benign chondral lesion abruptly juxtaposed to a high-grade non-cartilaginous component
is the classical definition of a chondrosarcoma [1]. The non-cartilaginous component is typically an
osteosarcoma, fibrosarcoma or malignant fibrous histiocytoma with rare instances of leiomyosarcoma, giant
cell tumor and rhabdomyosarcoma [2].
Conclusion: We report our rare instance of squamous dedifferentiation of a dedifferentiated
chondrosarcoma along with other five cases that have been reported so far in the literature

Published: April 2020

A significant amount of concern has been expressed about all the way in which technical vocational Education training (TVET) is taught in Nigeria and particularly in technical collegesin Niger State. This concern stems partly from the fact that the nation cannot grow its human and material resources effectively without sufficient and well-trained manpower at all educationallevels. The study therefore investigates the professional skills training needs of technical vocational teachers in technical colleges in Niger State. The sample method used for the survey.The study population comprised of all technical college teachers in Niger state; the sample included all the sixty (60) technical teachers that made up the population. For data collection,professional training competencies Needs of Technical Vocational Teachers Questionnaire were used. The test-retest method was also used to determine the coefficient of reliability of which0.72 was obtained. The data collected were analyzes using the statistical method Mean and Standard deviation. The findings from this study showed that the teachers of technical colleges inNiger state of Nigeria are not exposed to workshops, seminars, conferences and other means of acquiring basic technical knowledge, skills and attitudes and that innumerable teachers oftechnical colleges are not competent. It was therefore recommended that all technical teacher training institutions function in performance as a matter of necessity and produce anappropriate curriculum which will take on the necessary skills for our new technical teachers in training and those already in the field through in-service training.

The Legal Debate on the Phenomenon of ‘White Marriages’ in Contemporary Iran
Authors: Rodziewicz Magdalena
Published: April 2020

The rising popularity of ‘white marriages’, relationships between a man and a woman who live together but are not married, has caused a commotion in the Iranian public sphere in the last few years. The debate includes state institutions and religious circles, who feel anxious about the change in gender relations among Iranians, but also academics who elaborate on the causes and consequences of the phenomenon. An important aspect of this controversy concerns legal issues, since according to Shiite law any intimate relationship of an unmarried couple is considered illegal. This article analyses this key aspect of the ongoing dispute and attempts to elaborate on the question of how the gap between people’s expectations and desires and the legal capacity of Islamic rulings is addressed in contemporary Iran.

Authors: Kristianus Kristianus , Magdalena Magdalena , Lala Carolina
Published: April 2020

This research is backed by the condition of the community located in the border area of Indonesia-Malaysia especially in Entikong subdistrict of Sanggau Regency. As the frontier area of social and cultural life of community education in this region has always been a concern especially in conjunction with Malaysian Sarawak.  The inhabitants of this region generally embraced Catholicism and Catholic missionaries establishing schools of KINDERGARTEN to high school which are equipped with dormitories. The problem in this study is how the Catholic religious education influences the dialectics of Dayak culture in the region. Data taken using qualitative method is by observation, interviews and living with the community there. The study was held in July-September 2018. The results concluded that the education developed by Catholic missionaries has an effect on the dialectics of Dayak culture in this area. Besides education, other factors also affect the history, politics, and daily life at the border.  Another conclusion is that the Catholic missionary (the work of the education that has been developed) has an effect on the identity of Dayak culture in this region, Dayaks are more confident. This could be so because Catholic missionaries appreciate Dayak culture.  It is clear that the education developed by the Catholic religion plays a role in the formation of basic and primary materials for the formation of Dayak cultural dialectics in Entikong and other border areas in West Kalimantan.
Scipp: Scientific data handling with labeled multi-dimensional arrays for C++ and Python
Authors: Heybrock Simon , Arnold Owen , Gudich Igor , Nixon Daniel , Vaytet Neil
Published: April 2020

scipp is heavily inspired by the Python library xarray. It enriches raw NumPy-like multi-dimensional arrays of data by adding named dimensions and associated coordinates. Multiple arrays are combined into datasets. On top of this, scipp introduces (i) implicit handling of physical units, (ii) implicit propagation of uncertainties, (iii) support for histograms, i.e., bin-edge coordinate axes, which exceed the data’s dimension extent by one, and (iv) support for event data. In conjunction these features enable a more natural and more concise user experience. The combination of named dimensions, coordinates, and units helps to drastically reduce the risk for programming errors. The core of scipp is written in C++ to open opportunities for performance improvements that a Python-based solution would not allow for. On top of the C++ core, scipp’s Python components provide functionality for plotting and content representations, e.g., for use in Jupyter Notebooks. While none of scipp’s concepts in isolation is novel per-se, we are not aware of any project combining all of these aspects in a single coherent software package.
Evaluation of scattered radiation dose received by medical staff during uterine artery embolization in the operating room
Authors: Chiang Hsien-Wen , Chiang Hsien-Jen , Li Jung-Hui , Tsang Leo Leung-Chit
Published: April 2020

BACKGROUND:

The air kerma radiation doses have gained much attention since the operating room interventional radiology is a place where medical staff are exposed to a fluoroscopy environment and gain a cumulative dose during the uterine artery embolization procedure.

OBJECTIVE:

We aimed to evaluate the radiation dose received by medical staff by applying a flat X-ray machine in the surgical room during uterine artery embolization.

METHODS:

An ATOM humanoid model was laid on the operating table and simulated a patient. The scattered radiation dose received by the radiologist, anesthetist and radiologic technologist was evaluated. The scintillation detector was adopted. The measurement points were 50 cm, 100 cm and 150 cm above the floor, representing the limbs, abdomen and thyroid level, respectively. We compared the X-rays under different tube voltages of 70, 80, and 90, respectively and frames per second (FPS) of 30, 15, and 7.5, respectively. We configured the dose level per pulse of 40 nGy with a fixed detector.

RESULTS:

In Section 1, when the tube voltage was 70 kVp and 7.5 FPS, the average radiation doses of limbs, abdomen and thyroid level was 0.48, 1.3 and 1.9 [Formula: see text]Sv/min respectively. When the tube voltage was 80 kVp and the fluoroscopy decreases from 30 FPS to 7.5 FPS, 58% of the radiation dose was reduced. When the tube voltage was 90 kVp, the radiation dose in the lead garment increased 31–177% in comparison to when the tube voltage was 80 kVp. Sections 2 and 3 were far away from the central ray, so the highest radiation dose 100 cm above the floor were 0.05 and 0.02 [Formula: see text]Sv/min.

CONCLUSIONS:

Lead garment can effectively reduce medical staff from occupational doses with an average attenuation rate of 90%. 80 kVp was most commonly used. Fluoroscopy 7.5 FPS was used 100 cm above the floor in A section and the lowest radiation dose was 1.33 [Formula: see text]Sv/min. The operator should decrease the duration of X-rays or adopt suspended lead shielding to decrease the radiation dose received by the operator. When kVp increases, the penetration increases. Decreasing FPS cannot decrease occupational doses of medical staff.

Authors: Lin Jirui , Xiao Laiyuan , Wu Tao
Published: April 2020

BACKGROUND:

Video-based face recognition (VFR) is one of the frontier topics in the domain of computer vision, which aims to automatically track and recognize facial regions of interests (ROIs) in video sequences.

OBJECTIVE:

In videos with multiple faces, the trajectories of individuals are incredibly complex. This is less studied than videos with a single face per frame.

METHODS:

In this paper, we present a multi-trajectory incremental learning (MTIL) algorithm, which categorizes trajectories using a Euclidean distance-based greedy algorithm and estimates the most likely labels for each trajectory by incremental learning to correct their classification and improve the accuracy of recognition. Furthermore, this study proposes an enhanced detection method that combines face detection with a robust tracking-learning-detection (TLD) algorithm to improve the performance of face detection in video. The method can also be extended for medical video recognition applications such as gesture recognition control based medical system.

RESULTS:

Experiments on Honda/UCSD and BMP (seq_mb) database demonstrate that our method can improve the face detection and face recognition (single or multiple) performance. The method also performs well on the gesture recognition system.

CONCLUSION:

The proposed MTIL algorithm can significantly improve the performance of the VFR system and the gesture recognition system.

Published: April 2020

BACKGROUND:

The large differences of electrical characteristics can be used to reflect the physiological and pathological changes about biological tissues, and it can provide evidence for the early diagnosis and treatment of cancer in potential applications.

OBJECTIVE:

This paper describes a method called Applied Current Thermoacoustic Imaging (ACTAI) and explores the theory and demonstrates a low conductivity numerical simulation and fresh pork experimental studies.

METHODS:

In this paper, firstly, the principle of ACTAI is studied. In ACTAI, a target is applied with a microsecond width Gaussian pulse current. Then the target absorbs Joule heat and expands instantaneously, sending out thermoacoustic waves. The waves contain the conductivity information of the target. The waves received by sound transducers are processed by the time inversion method to reconstruct the sound source distribution of the target to illustrate the conductivity information of the target. Secondly, a square model with low conductivity was used as a target to conduct numerical simulation of ACTAI. Lastly, a fresh pork experiment study was conducted.

RESULTS:

The presented experimental results suggest that ACTAI can identify the conductivity changes information of the target with perfect imagery contrast and deep penetration.

CONCLUSION:

The ACTAI modality would benefit from the noncontact measurement and can be convenient for clinical application.

Authors: Fan Xiaoli , Zhao Chaoyi , Zhang Xin , Luo Hong , Zhang Wei
Published: April 2020

BACKGROUND:

Mental workload is one of the contributing factors to human errors in road accidents or other potentially adverse incidents.

OBJECTIVE:

This research probes the effects of mental workload on the electroencephalographic (EEG) and electrocardiogram (ECG) of subjects in visual monitoring tasks, based on which a comprehensive evaluation model for mental workload is established effectively.

METHODS:

Three degrees of mental workload were obtained by monitoring tasks with different levels of difficulty. 20 healthy subjects were selected to take part in the research.

RESULTS:

The subjective scores showed a significant increase with the increase of task difficulty, meanwhile the reaction time (RT) increased and the accuracy decreased significantly, which proved the validity of three degrees of mental workload induced. For the EEG parameters, a significant decrease of [Formula: see text] energy was found in Frontal, Parietal and Occipital with the increase of level of mental workload, as well as a significant decrease of [Formula: see text] energy in Frontal, Central and Occipital, meanwhile a significant increase of [Formula: see text] energy occurred in Frontal and Occipital. There was a significant decrease of [Formula: see text]/[Formula: see text] in Occipital, and significant increases of [Formula: see text]/[Formula: see text] and ([Formula: see text] in Frontal, Central and Occipital, meanwhile ([Formula: see text] and WPE decreased significantly in Frontal and Occipital. Among the ECG parameters, it was shown that Mean RR, RMSSD, HF_norm and SampEn decreased significantly with the increase of task difficulty, while LF_norm and LF/HF showed significant increases. These EEG indictors in Occipital and ECG indictors were chosen and constituted a multidimensional original sample. Principal Component Analysis (PCA) was used to extract the principal elements and decreased the dimension of sample space in order to simplify the calculation, based on which an effective classification model with accuracy of 80% was achieved by support vector machine (SVM).

CONCLUSION:

This study demonstrates that the proposed algorithm can be applied to mental workload monitoring.

Authors: Cao Lei , Fan Chunjiang , Wang Zijian , Hou Lusong , Wang Haoran , Li Gang
Published: April 2020

BACKGROUND:

Mental task-based brain computer interface (BCI) systems are usually developed for neural prostheses technologies and medical rehabilitation. The mental workload was too heavy for the user to manipulate BCI effectively. Fortunately, electroencephalography (EEG) signal is not only used for BCI control but also relates to the changes of mental states.

OBJECTIVE:

We proposed a novel method for identifying non-effective trials of Steady State Visual Evoked Potential (SSVEP)-based BCI.

METHODS:

We used the subject-dependent and subject-independent alertness models identifying non-effective trials of SSVEP-BCI systems.

RESULTS:

The result implied that the subject-dependent alertness model was most useful for improving the classification accuracy in the task. However, the subject-independent alertness model could enhance the prediction ability of SSVEP-based BCI system.

CONCLUSION:

In comparison to the conventional canonical correlation analysis (CCA) method without alertness-model filtering, the raise of precision was valuable for the technical development of BCI works. It demonstrated the effectiveness of our proposed subject-dependent and subject-independent methods.

Authors: Peng Yangzhi , Su Yue , Jiang Yong
Published: April 2020

OBJECTIVE:

To study the molecular mechanism of warming and tonifying kidney-yang recipe (WTKYR) in the treatment of depression.

METHODS:

SD rats were divided into a control group, model group, WTKYR group, and fluoxetine group. Each group consisted of 21 rats. The chronic unpredictable mild stress model was used. Body weighing and SPT were performed regularly. After treatment, histopathology of the brain tissue was performed, and concentrations of 5-HT (5-hydroxytryptamine), NE (norepinephrine), and DA (dopamine) in the hippocampus were determined.

RESULTS:

The WTKYR group showed higher body weight and sucrose consumption than the control groups. Moreover, the concentrations of 5-HT, NE, and DA in the hippocampus were significantly different in the WTKYR group in comparison to those in the other groups. The hippocampus histomorphology of the WTKYR group exhibited less dematous pyramidal cells and mild inflammatory cell infiltration.

CONCLUSION:

The treatment effect of WTKYR in depression may be based on improvement in the content of 5-HT, NE, and DA in the hippocampus, extenuating edema of the cortical surface and pyramidal cells and decreasing the infiltration of inflammatory cells into hippocampus tissue.
