La conjunción del Derecho y la ciencia para la determinación de la sostenibilidad de las energías renovables en el futuro paradigma energético de Europa
Authors: Pascual Núñez María , Sanz San Miguel Carlos 
Published: May 2021

Una de las reticencias sociales más extendidas acerca del uso de combustibles de biomasa son las emisiones que producen. En el caso de la biomasa forestal, son puntos conflictivos para el sector ambientalista el recuento y la gestión del carbono absorbido, los posibles daños a la biodiversidad y a la calidad de los aprovechamientos forestales, y el posible aumento de emisiones. Por el contrario, el sector técnico apuesta por una gestión forestal sostenible, mediante el uso de técnicas avanzadas que permitan conocer cómo funcionan los mecanismos de los bosques como sumideros de carbono.
Los riesgos ambientales del uso energético de los biocombustibles pueden ser revertidos mediante el empleo de parámetros técnicos. La normativa europea establece criterios de sostenibilidad para la biomasa con destino energético, pero no fija parámetros acerca de la sostenibilidad del resto de fuentes renovables.
Este trabajo se basa en la necesaria imbricación entre la técnica normativa consagrada el programa europeo “Legislar mejor para obtener mejores resultados - Un programa de la UE” y la ciencia, por una mayor sostenibilidad del uso de fuentes de energía renovables.
One of the most widespread social reservations about the use of biomass fuels is the emissions they produce. In the case of forest biomass, points of conflict for the environmental sector are the counting and management of the absorbed carbon, the potential harm to biodiversity and the quality of forest harvesting, and the probable rise in emissions. On the other hand, the technical sector is committed to sustainable forest management, through the use of advanced techniques that allow us to understand how the mechanisms of forests work as carbon sinks.
The environmental risks of the energy use of biofuels can be reversed through the use of technical parameters. European regulations establish sustainability criteria for biomass for energy purposes, but do not set parameters for the sustainability of other renewable sources.
This work is based on the necessary imbrication between the regulatory technique enshrined in the European programme "Better Regulation for better results - An EU agenda" and science, for greater sustainability in the use of renewable energy sources.

Published: May 2021

El presente trabajo se proyecta sobre la política marítima integrada diseñada por la Unión Europea, con miras a cotejarla desde los criterios de la sostenibilidad que la propia Unión se ha impuesto y contrastar su eficacia y utilidad para la consecución de unos objetivos de calidad medioambiental de los mares y océanos que a día de hoy se formulan con carácter imperioso y urgente.
This paper addresses the integrated maritime policy designed by the European Union to compare it against the criteria of sustainability that the Union has self-imposed. The aim is to test its effectiveness and usefulness in achieving the imperative environmental quality objectives of the seas and oceans.
S’agit-il d’une situation de violence sexuelle ?
Authors: Rousseau Catherine , Bergeron Manon 
Published: May 2021

Les mécanismes qui sous-tendent l’identification ou non d’une situation en tant que violence sexuelle influencent la façon de comprendre et de qualifier l’évènement subi. Alors que des chercheures et chercheurs ont évalué la prévalence de la violence sexuelle malgré sa sous-déclaration, peu ont exploré le témoignage des personnes victimes, que ces dernières y réfèrent comme étant de la violence sexuelle ou non. En s’appuyant sur 247 récits, cette recherche propose une analyse qualitative des repères mobilisés par les étudiantes universitaires de premier cycle pour décrire et interpréter la situation vécue, selon la perception de son caractère inacceptable ou non. Les objectifs sont 1) de décrire les repères interpellés dans la description des situations de violence sexuelle en milieu universitaire subies par les étudiantes universitaires de 1er cycle ; et 2) d’explorer de quelle façon les discours associés aux mythes et aux scripts liés aux violences sexuelles peuvent moduler la façon de qualifier les situations de violence sexuelle en milieu universitaire subies par ces étudiantes. Cette recherche adopte un cadre d’analyse féministe de la violence sexuelle. Les résultats se déclinent en trois grandes catégories. D’abord, la majorité des récits font état du caractère inacceptable de la situation en se basant sur différents repères tels que l’absence de consentement sexuel, la répétition de comportements sexuels non désirés ou les répercussions vécues à la suite de la violence sexuelle (n = 162). Ensuite, des récits (n = 79) dévoilent des qualifications qui freinent l’identification du caractère inacceptable de la situation, que ce soit par des termes reflétant une minimisation ou une banalisation des comportements subis ou par une tolérance à l’égard de ce type de situation. Enfin, la troisième catégorie met en lumière l’incertitude de qualifier ce qui s’est produit comme étant une situation de violence sexuelle (n = 6). Ces résultats seront discutés à l’égard des repères théoriques choisis.

Abstract

Background:
This study quantified and compared weekday and weekend patterns of device-measured physical activity (PA) and sedentary behavior between youth with pediatric multiple sclerosis (MS) and controls for the purpose of informing future PA behavior change interventions.

Methods:
Participant data were obtained from 3 ongoing observational studies, and the sample included 40 participants with pediatric MS and 41 controls. Light PA (LPA), moderate to vigorous PA (MVPA), and sedentary behavior data were collected using activity monitors (ActiGraph LLC) over 1 week. The main analysis involved a 2-way mixed factor analysis of variance with group as a between-subjects factor (pediatric MS vs control) and day as a within-subjects factor (weekday vs weekend day).

Results:
There was no group by day interaction from the analysis of variance for percentage of activity monitor wear time spent in LPA, MVPA, or sedentary behavior. There was no effect of group for LPA, MVPA, or sedentary behavior. There was an effect of day of week on percentage of day spent in LPA, MVPA, and sedentary behavior.

Conclusions:
These results suggest that youth with pediatric MS and controls were less physically active and more sedentary on weekends than on weekdays, but there were no differences between groups in PA and sedentary behavior overall or by day of the week. Physical activity interventions may be more successful by initially targeting weekend day activity.

Authors: Roelens Ben 
Published: May 2021

Business Information Systems research deals with the conceptualization, development, introduction, maintenance and utilization of systems for computer-assisted information processing within companies and enterprise-wide networks. This CSIMQ issue contains five articles that deal with various information system (IS) issues, including IS security, product-related ISs, blockchain technology and sensor technology. The call for this issue was particularly targeted towards extended articles of two workshops that were held in conjunction with the 13th IFIP WG 8.1 working conference on the Practice of Enterprise Modelling. The first is the BES 2020 workshop (i.e., 1st Workshop on Blockchain and Enterprise Systems), which has the ambition to change the way one thinks, designs and implements ISs. The second one is ManComp 2020 (i.e., 5th Workshop on Managed Complexity), which is focused on approaches and methods for managing the complexity of ISs and IS interaction within ecosystems.

Previous studies have suggested that the presence of circulating nucleic acids (cell-free DNA) in seminal plasma may indicate disease states. However, the potential association between cell-free DNA (cfDNA) levels in seminal plasma and sperm fertility parameters has not yet been definitively determined.
In this study, we will compare seminal free DNA levels between normozoospermic samples and those from different pathologies related to characteristic parameters of sperm quality (asthenozoospermia, azoospermia, teratozoospermia, oligozoospermia and a few samples with a high fragmentation index) in order to detect a potential association between free DNA levels in seminal plasma and these different pathologies of male fertility.
The recovery of free DNA from our different samples was done with the MACHEREY-NAGEL NucleoSpin® kit. This kit allows isolation of DNA from cell-free biological fluids using rapid silica column procedures. The quantification of free DNA in our samples was performed by quantitative PCR (RT-qPCR).
Our results showed a significant difference in the level of free seminal DNA between normozoospermic samples and oligozoosperimic, teratozoosperimic, azoosperimic samples and those with a high DNA fragmentation index. On the other hand, no significant difference in the level of seminal free DNA was noted between normozoospermic and asthenozoospermic samples.
These results suggest that seminal free DNA may be an important biomarker in the assessment of human sperm fertility.

Introduction: Community based health financing mechanism is referred to as a process whereby household in a community finance or co finance the recurrent and capital cost associated with a given set of health services thereby also include management of financial scheme and organization of health services.
Iccm as a strategy to providing integrated case management services for two or more illness including diarrhea, malaria, pneumonia among children from two to upto five years. It is a community approach where lay persons are trained on management of the three diseases. This approach is being funded by foreign donor. However, there was stipulated period in which this support would elapsed and the support from the state Government may not be feasible. In an attempt to source for financing of iccm, this study aim at determining the willingness of the caregiver to use Community financing approach through payment of Premium to finance this community intervention (iccm). The concept of willingness to pay is maximum price a consumer is willing to pay for a given product or services.
Materials and Methodology: A descriptive Cross sectional study was carried out among four hundred respondents that were selected using Multi stage sampling technique. Data was collected, coded and entered into a computer. Analysis was carried out using SPSS. Chi Square and logistic regression was used as a test of significance. Level of significance was set at Pvalue less than 0.05.
Results: Twenty two percent of the respondents had good knowledge of iccm activities. Less than half of the respondents 41.3% were satisfied with iccm activities. Majority of the respondents 93.3% were willing to pay. Out of this, half of them 50.0% said they could only afford to pay less than 1000 naira per annum and 72.8% said the convenient time to pay was during the harvesting time. Factors influencing willingness to pay include Age, marital status and income level ( Pvalue <0.05). Knowledge and level of satisfaction were not influencing factors. The predictor of willingness to pay are aged 38-47 years and income of less than 5000 naira.
Conclusion and Recommendation: There was willingness of the respondents to contribute for financing and sustainability of iccm in Niger State but the amount the majority of them were willing to pay was less than 1000 naira which might not able to sustain the iccm activities. There may be need for further research to determine amount needed for the annual activities and hence sustainability of iccm. The Government should show much responsibilities toward financing of iccm. Bi-apartite arrangement could be made between State Government and the Communities with iccm in place on how to share some responsibilities of iccm activities.

Published: May 2021

Background: Cervical cancer is the most common gynaecological cancer in developing countries. The World Health Organisation estimated that there were about 570,000 new cases of cancer of the cervix in 2018 and about 311,000 women died of the disease.
Objective: To determine the prevalence and characteristics of patients with cervical cancer at the Federal Medical Centre, Yenagoa, Bayelsa State, Nigeria.
Materials and Methods: This was a descriptive study which involved all the patients with histologically confirmed cervical cancer managed at the gynaecological unit of the hospital from 1st January, 2016 to 31st December, 2020. Information was extracted from the gynaecological records and entered into a predesigned proforma. All available data were retrospectively analysed with SPSS version 23.0, and results were presented in tables and frequencies.
Results: There were 31 cases of cervical cancers out of the 2,478 gynaecological cases seen. The prevalence of cervical cancer was 1.25%. About one-third of the women were in the sixth decade of life (32.3%). About half of the women were diagnosed at Stage 2 of the disease (51.6%) and squamous cell carcinoma accounted for 80.6% of the cancers. Radiotherapy was the most used treatment option (64.5%). About one-quarter died (25.8%).
Conclusion: Most of the patients in this study presented in the advanced stages of the disease, with death of about one-quarter of them. Prevention and early presentation to the hospital are key in the prevention of poor quality of life and deaths. All hands must be on deck to tackle this disease.

Authors: Niromanesh S , Laghaii S , Mosavi‐Jarrahi A 
Published: July 2002

AbstractObjective:To study the effect of calcium supplementation on reduction of pre‐eclampsia in Iranian women at high risk of pre‐eclampsia.Methods:Thirty pregnant women at high risk of developing pre‐eclampsia were randomized to 2 g of daily calcium and placebo. Subjects and investigators were blinded to treatment allocation. The inclusion criteria were positive rollover test, having at least one risk factor for pre‐eclampsia, between 28 and 32 weeks of pregnancy, and blood pressure less than 140/90 (mmHg). Exclusion criteria were having any chronic condition. Pre‐eclampsia was defined as systolic/diastolic blood pressure over 140/90 plus proteinuria. All the subjects were followed up to delivery.Result:A sevenfold reduction in the occurrence of pre‐eclamsia were seen among the calcium group compared with the placebo group (7 out of 15 developed pre‐eclampsia in control group vs. 1 out of 15 in calcium group,P=0.014). No major effect on pregnancy induced hypertension was seen (66% in placebo and 76% in calcium group developed hypertension) but the onset of hypertension was delayed 3 weeks in the calcium group. A longer duration of pregnancy was seen in calcium than placebo (mean±S.D.=37±2 for calcium and 34±2 for placebo,P<0.05). Infants born to the calcium group, on average, were 552 g heavier than infants born to the placebo group,P<0.05.Conclusion:Calcium supplementation is beneficial for preventing pre‐eclampsia among Iranian women at high risk of developing pre‐eclampsia.
Teaching safe sex in school
Authors: Short R. 
Published: July 2002

AbstractObjective: To teach safe sex practices to adolescents in school, before they start to become sexually active, using peer group education. Method: To send young medical students back to their old schools to do the teaching, and to get them to make videos suitable for showing to teenage audiences that can be widely circulated to all schools. Results: The program has been running in Australia since 1992, and has proved highly popular with school teachers, school children, and particularly with medical students. We are now working with medical schools in Beijing and Shanghai, at the invitation of the Chinese Ministry of Health, to see if we can adapt our program to a very different cultural setting. Conclusion: Educating children about Safe Sex is one of the most effective ways of postponing their onset of sexual activity. It is also the best investment that we can make to ensure people's future reproductive health; if they start right, there is every hope that they will stay right.
Building operations management theory through case and field research
Authors: Meredith Jack 
Published: July 2002

AbstractCase and field research studies continue to be rarely published in operations management journals, in spite of increased interest in reporting such types of studies and results. This paper documents the advantages and rigor of case/field research and argues that these methods are preferred to the more traditional rationalist methods of optimization, simulation, and statistical modeling for building new operations management theories. In the process of describing the constructs of inference and generalizability with reference to case research, we find the existing definitions inadequate and thus extend and refine them to better discriminate between alternate research methodologies. We also elaborate on methods for increasing the generalizability of both rationalist and case/field research studies. A major conclusion is that these alternate research methods are not mutually exclusive and, if combined, can offer greater potential for enhancing new theories than either method alone.
The relationship between total quality management practices and operational performance
Authors: Samson Danny , Terziovski Mile 
Published: July 2002

AbstractTotal quality management (TQM) has been a widely applied process for improving competitiveness around the world, but with mixed success. A review of the literature revealed gaps in research in this area of quality/operations management, particularly in the area of empirical testing of the effectiveness of TQM implementation. The aim of this study was to examine the total quality management practices and operational performance of a large number of manufacturing companies in order to determine the relationships between these practices, individually and collectively, and firm performance. We used a large data base of 1200 Australian and New Zealand manufacturing organisations. The reliability and validity (construct, content, criterion) of the practice and performance measures were evaluated. Our study showed that the relationship between TQM practice and organisational performance is significant in a cross‐sectional sense, in that TQM practice intensity explains a significant proportion of variance in performance. Some but not all of the categories of TQM practice were particularly strong predictors of performance. The categories of leadership, management of people and customer focus were the strongest significant predictors of operational performance. This is consistent with literature findings that behavioural factors such as executive commitment, employee empowerment and an open culture can produce competitive advantage more strongly than TQM tools and techniques such as process improvement, benchmarking, and information and analysis.
Contribution of disc degeneration to osteophyte formation in the cervical spine: a biomechanical investigation

Published: July 2002

AbstractCervical spine disorders such as spondylotic radiculopathy and myelopathy are often related to osteophyte formation. Bone remodeling experimental—analytical studies have correlated biomechanical responses such as stress and strain energy density to the formation of bony outgrowth. Using these responses of the spinal components, the present study was conducted to investigate the basis for the occurrence of disc‐related pathological conditions. An anatomically accurate and validated intact finite element model of the C4‐C5‐C6 cervical spine was used to simulate progressive disc degeneration at the C5‐C6 level. Slight degeneration included an alteration of material properties of the nucleus pulposus representing the dehydration process. Moderate degeneration included an alteration of fiber content and material properties of the anulus fibrosus representing the disintegrated nature of the anulus in addition to dehydrated nucleus. Severe degeneration included decrease in the intervertebral disc height with dehydrated nucleus and disintegrated anulus. The intact and three degenerated models were exercised under compression, and the overall force—displacement response, local segmental stiffness, anulus fiber strain, disc bulge, anulus stress, load shared by the disc and facet joints, pressure in the disc, facet and uncovertebral joints, and strain energy density and stress in the vertebral cortex were determined. The overall stiffness (C4‐C6) increased with the severity of degeneration. The segmental stiffness at the degenerated level (C5‐C6) increased with the severity of degeneration. Intervertebral disc bulge and anulus stress and strain decreased at the degenerated level. The strain energy density and stress in vertebral cortex increased adjacent to the degenerated disc. Specifically, the anterior region of the cortex responded with a higher increase in these responses. The increased strain energy density and stress in the vertebral cortex over time may induce the remodeling process according to Wolff's law, leading to the formation of osteophytes. © 2001 Orthopaedic Research Society.
