A systematic review about animal models in homeopathic research: the last five years of PubMed indexed papers
Authors: Bonamin Leoni Villano , Cardoso Thayna Neves , Carvalho Aloisio Cunha , Amaral Juliana G
Published: August 2021

Background: This review is part of a special issue of Journal â€œHomeopathyâ€ (ELSEVIER) to be published in 2015, about the follow-up of researches published in the book titled â€œUltra-High Dilution, Physiology and Physicsâ€, written in 1994 and edited by PC Endler and J Schulte. In 2010 a critical and conceptual review about animal models in homeopathy and high dilution research was published by our group. Thus, the aim of this study is to know how models and conclusions have progressed in this field in the last five years. Animal models represent one of the most illustrative examples of the biological effects of homeopathy and high dilutions. The main contribution of these studies is the comprehension of biological features and the phenomenology towards the high dilutions effects upon living systems, which represents an important step to the understanding of mechanisms of action of homeopathic medicines.

Methods: 53 articles indexed in the PubMed database were systematically evaluated, in which 12 different animal species were used. 29 out of 53 reported studies were performed with â€œultra-highâ€ dilutions, whereas 14 studies were performed using dilutions in the range or below 10-23 or with commercial complexes (10).

Results: Only 02 negative results were reported, both using commercial complexes as tested medicine (one each in fish and bee model). Since 2010, the quality of employed methods, mainly statistics, has improved. The inclusion of more refined protocols, such as in vitro primary cell cultures and ex vivo protocols (10/53), often with three or more repetitions, could be observed. These new methods allowed to observe epigenetic mechanisms involved.

Conclusion: The demonstration of biological effects of homeopathy on animal models, in the past 5 years, is more refined than those previously described, helping in the development of paths to the mechanism of action discovery.
An improved and continuous synchronization of the Greenland ice-core and Hulu Cave U-Th timescales using probabilistic inversion
Authors: Muschitiello Francesco
Published: August 2021

Abstract. This study presents the first continuously measured transfer functions that quantify the age difference between the Greenland Ice-Core Chronology 2005 (GICC05) and the Hulu Cave U-Th timescale during the last glacial period. The transfer functions were estimated using an automated algorithm for Bayesian inversion that allows inferring a continuous and objective synchronization between Greenland ice-core and Hulu Cave proxy signals. The algorithm explicitly considers prior knowledge on the maximum counting error (MCE) of GICC05, but also samples synchronization scenarios that exceed the differential dating uncertainty of the annual-layer count in ice cores, which are currently not detectable using conventional tie-point alignments or wiggle-matching techniques. The consistency and accuracy of the results were ensured by estimating two independent synchronizations: a climate synchronization based on climate proxy records, and a climate-independent synchronization based on cosmogenic radionuclide data (i.e. 10Be and 14C). The transfer functions are up to 40 % more precise than previous estimates and significantly reduce the absolute dating uncertainty of the GICC05 back to 48 kyr ago. The results highlight that the annual-layer counting error of GICC05 is not strictly correlated over extended periods of time, and that within certain Greenland Stadials the differential dating uncertainty is likely underestimated by 7.5–20 %. Importantly, the analysis implies for the first time that during the Last Glacial Maximum GICC05 overcounts ice layers by 15–25 % –a bias attributable to a higher frequency of sub-annual layers due to changes in the seasonal cycle of precipitation and mode of dust deposition to the Greenland Ice Sheet. The new timescale transfer functions provide important constraints on the uncertainty surrounding the stratigraphic dating of the Greenland age-scale and enable an improved chronological integration of ice cores, U-Th-dated and radiocarbon-dated paleoclimate records on a common timeline. The transfer functions are available as supplements to this study.

Shaping Migrants as Threats: Multilayered Discretion, Criminalization, and Risk Assessment Tools
Authors: Gundhus Helene O. I.
Published: August 2021

This article examines Operation Migrant, initiated by the Norwegian police following the so-called migration crises in Europe in 2015. One of its central aims was, by predicting challenges related to increased migration, to improve resource allocation and prevent crime. By drawing on research on risk and threat assessment as a form of power, this article aims to analyze how risk categories are distributed and translated into a multilayered institutional arrangement where migration is policed as a potential crime. The article examines the indicators that the risk assessments are based on and the measures applied and investigates how discretionary practices make immigrants objects for law enforcement and policing. The article contributes to research on migration control in an ordinary police context, where immigration identity checks become part of the crime reduction strategy. Applying the concept of interpretive flexibility (Collins 1981), I will identify the steps in this chain of translation to explore the leap from targeting potentially criminal asylum seekers to targeting broader groups with temporary residency in Norway. The article analyzes the conditions determining how policing, technologies, and migrants are “co-constructed” in a chain of mediation and translation, which reinforces the view of migrants as risky and criminal. The final section discusses how risk and threat analysis is affected by the notion of the “crimmigrant other” (Franko 2020). In Norway, selectively targeting unwanted migrants as criminals has become dominant in police decision-making at a policy level and everyday practices affecting not only third country nationals but also unwanted eastern Europeans.
“I call it a system.” Unauthorized Migrants’ Understandings of the Long Reach of Dutch Internal Migration Controls
Authors: Kox Mieke , Staring Richard
Published: August 2021

We draw on the concept of deportability to show how unauthorized migrants who (used to) live in the Netherlands perceive and experience Dutch internal-control mechanisms. We first conclude that these migrants’ deportability has serious legal, social, and existential effects on them, which they feel long after their return or deportation to their home country. Second, we state that unauthorized migrants evaluate the Dutch internal-control mechanisms as “one system” in which they distinguish three important, interlinked layers, consisting of (1) divergent actors, (2) laws and policies inside and outside the migration control domains located within (3) different geographies. This implies that individual nation-states, through their internal control mechanisms, also contribute to the externalization of migration control at a supranational level. We conclude that the state’s internal migration controls bring about immobility not only in the countries of settlement but also in the transit and home countries.
“The adventure is not easy.” The Discretionary Politics of Social Suffering and Agency in Post-Deportation Narratives in Southern Mali
Authors: Schultz Susanne U
Published: August 2021

Drawing on eight months of ethnographic fieldwork in the West African state of Mali (2014–2016), this article delves into the local, national, and transnational effects of (externalized) European and North African deportation regimes and reactions to them by civil society actors and deportees themselves. This work aims to contribute to a better understanding of how geographical, physical, social, and psychological spaces are reshaped through interactions with bordering practices. Deportation generally takes the form of (il)legal, bureaucratic measures and violent interventions that are perceived as deeply unjust. They generate anger, alienation, and uncertainty among those deported and their families and associates. By seeking patterns in the accounts of social suffering in deportees’ narratives, the article seeks, empirically and analytically, to unravel multilevel bordering practices through examining localized, agentic forms of bordering power. The post-deportation context involves southern Mali, an area subject to dramatic desertification and loss of sustainable livelihoods.
Web-Based and Face-To-Face Autonomy-Supportive Intervention for Physical Education Teachers and Students’ Experiences
Authors: Tilga Henri , Kalajas-Tilga Hanna , Hein Vello , Koka Andre
Published: August 2021

The most of the previous autonomy-supportive interventions conducted have been partially effective and used only web-based or face-to-face approach. In the current study, a combined web-based and face-to-face intervention for physical education (PE) teachers was tested to examine whether it would lead to significant changes in students’ self-reports of autonomy-supportive and controlling behaviours, psychological need satisfaction and frustration, and intrinsic motivation. Participants were 57 PE teachers (Mage = 45.70, SD = 12.79) and their 858 middle-school students (Mage = 13.22, SD = 0.75). A randomized controlled design was adopted in which PE teachers and their students were assigned to the combined face-to-face and web-based, face-to-face alone, web-based alone or control group. Face-to-face intervention was provided to PE teachers within one day in an 8-hour workshop and web-based intervention was provided to PE teachers for a period of four weeks. The combined face-to-face and web-based intervention group was the only study group that demonstrated statistically significant changes in all the study variables (i.e., significant increase in cognitive, organisational, and procedural autonomy-supportive behaviour, in psychological need satisfaction for autonomy, competence and relatedness, and in intrinsic motivation, whereas significant decrease in intimidation, controlling use of grades, and negative conditional regard, and in psychological need frustration for autonomy, competence, and relatedness) compared to the control group at a one-month follow-up. There were no significant differences in any of the study variable, except organisational autonomy support and intimidation, between the web-based intervention group and face-to-face intervention group. Both web-based and face-to-face study group students reported significant gains in most of the study variables compared to the control group students at a one-month follow-up. The current findings suggest that future autonomy-supportive interventions for PE teachers should aim to use combined interventions of face-to-face and web-based approach to gain the greatest intervention effects.

Impact of Female Employment and Education on Child Health Care: A Case Study of Pakistan
Authors: Fouzia Mrs. , Gillani Durdana Qaiser , Ahmad Shahbaz
Published: August 2021

The majority of the females become a part of the labour force to share the burden of families in Pakistan, and they contribute to the cost of their children's health care. This issue is highlighted in this study. This research focuses on females’ education and their involvement in the labour market and child health care in Pakistan. The activities that affect the health of children are analysed here by using time use survey data. The ordinary least squares regression technique is used to find an association of female related and household related variables and their child health care. The results reveal that female’s age and employment affect child health care negatively. However, female’s age square and child health care are positively related. Moreover, the mother’s educational grade dummies, assets of family and family size positively affect the child's health care. The study concludes that mature females provide better care to their children's health. However, employed females have less time to care for their child's health. Those females who belong to the joint family system can better look after their children due to their share of household responsibilities. In addition, educated and financially strong females provide better health care to their children. The study suggests that lower-cost care centers can make the high participation of females in the labour market. Moreover, mothers should give too much time to their children for better care. There is a severe need for improvement of the higher education of females so that they can better utilize their education in caring for their children.

“Slippage” in the talent development environment of elite junior tennis players
Authors: Gowling Callum
Published: August 2021

“Slippage” occurs when there is a mismatch between the intended message communicated (by coach, parent, or talent development environment) and the received message by junior tennis players.  The concept of slippage has received attention in educational settings, but research has yet to investigate the possible effects on junior tennis players.  The purpose of this study was to examine the experiences of 8 UK, elite junior tennis players and describe what it is like to perform in the elite junior context.  An Interpretative Phenomenological Analysis (IPA) of 8 elite junior tennis players (playing LTA Grade 2 and upwards) shows their insights into elite junior tennis.  This study found that (a) participants seek meaning behind their tennis experiences and they infer messages from their environment that are not intended, (b) “slippage” is associated with unintentional pressure, and (c) “slippage” is associated with a reduction of junior tennis players’ confidence.  The findings of this research contribute to an evolving, problematic epistemology of sports coaching and confirms that coaches can lose control of their intended message as players infer their own meanings from interactions within tennis.  The findings present governing bodies opportunities to inform coach education literature and consider how the difference between the intended coaching message and the received coaching message can impact the emotional state of junior tennis players.

Published: August 2021

Les PME en phase de développement sont exposées à deux catégories de risque à savoir le risque entrepreneurial et le risque managérial. Ce dernier est lié à l’informalité de la gestion de celle-ci. Dans les Pme camerounaises, on note une mauvaise organisation des activités, l’absence d’un système d’information et la déficience en outils permettant de mieux prévoir et d’assurer le pilotage de l’entreprise. Face à cela, l’opportunité de passer des leviers informels de contrôle vers des systèmes de contrôle formels en occurrence le contrôle de gestion (CDG) constitue une phase décisive pour les PME en quête de performance.  L’objectif de l’étude est d’identifier les étapes de structuration du CDG dans les PME en vue d’amorcer la phase de croissance. De ce fait, une étude a été menée auprès de huit (08) PME camerounaises et l’analyse du contenu thématique de chaque cas révèle que la structuration du CDG dans les PME est un processus qui s’effectue par étape successive. Il ressort des analyses que trois types de processus caractérisent l’organisation formelle de la PME à savoir le processus progressif, le processus stationnaire et le processus dit bloquer. Aussi, l’importance de la structuration du CDG doit s’inscrire dans une dynamique de type projet et privilégier une gestion par la compétence au détriment d’une gestion dite familiale.

Published: August 2021

Due to the high prevalence of typhoid fever and the periodic nature of Salmonella infections despite the various antimicrobial agents used to treat these infections, the need to open up new strategies for antimicrobial susceptibility rather than the MIC alone arises. This study determines the time-kill curves using four different antimicrobial agents: Gentamicin, Ceftriaxone, Cloxacillin, and Ofloxacin at different concentrations of 1x, 2x, and 4x of their respective MICs. The finding of this study reveals that at 1x MIC, all the antimicrobial agents used, except for Gentamicin, show non-bactericidal activity against the isolates after eight hours of exposure. This study suggests that analyzing the time-kill curves in typhoid fever treatment will help determine the appropriate dose to treat the infection.

Introduction: The EU strategy “Europe 2020” sets up the instruments and targets for better educational levels and training as social dialogue, awareness-levels raising, law enforcement in the field of EU and national legislation. There are efficient resource interactions with other policy areas such as public health and education. EU funds, such as the European Social Fund (ESF) and the European Program for Employment and Social Innovation (EaSI), will support the application of rules relating to health and safety at work. Purpose of this study is analysis and evaluation of the employees, knowledge about health and safety at the workplace and how effective were the conducted OHS training. Tasks: Defining the level of awareness of workers for possibilities of health damage at work. Measuring the level of OSH training support for the implementation of preventive approaches to health protection in the workflow. Studying the preliminary psychological attitude towards OHS training both for employers and employees. Method: Survey through a questionnaire held among workers and employees in several branches of the private sector. Results: The study provides summarized information on several subjects: workers’ knowledge about dangerous hazards in their own working environment; adherence of the safety at work rules; proper use of personal protective equipment and specific work protective equipment; types of training, outreach and education the employees have undergone; levels of basic knowledge of the law and regulations related to OHS; most common methods of OHS training and education and their interpretation for safety and health at work. Conclusions: Most workers are well aware of the health risks at their workplaces. All of them have passed at least one educational course related to OHS. More than 2/3 of the respondents have participated in several types of training. Workers have a basic knowledge of Bulgarian employment law, but it’s incomplete and can be extended to a better degree. The most common reason for participating in Health and Safety at work training is obligatory both by law or higher management of the company. There is a high need to supplement the OHS legislation.

Tükenmişlik, her meslek grubunda ortaya çıkabilecek psikolojik bir rahatsızlık olmakla birlikte özellikle hizmet sektöründe çalışan bireylerde daha sık görülebilmektedir. Havayolu şirketlerinin vitrini durumunda olan kabin ekiplerinin yüz-yüze hizmet vermeleri, emek yoğun çalışmaları, düzenli mesai kavramlarının olmayışı gibi etkenler bir takım sıkıntıları beraberinde getirmektedir. Tükenmişlik sendromunu yaşayan kabin ekibi çalışanlarının uçuşlarına katılmamaları, çalışırken işe odaklanamamaları, yolcuya verilen hizmetin düşük olması şirketler için de maliyet ve imaj kaybına neden olmaktadır. Bu çalışmada; kabin ekiplerinin tükenmişlik düzeylerinin ölçülmesi ve elde edilen sonuçların demografik faktörlere göre değerlendirilmesi amaçlanmıştır. Verileri elde etmek amacıyla Maslach Tükenmişlik Envanteri kullanılmış ve Antalya’da faaliyet gösteren bir özel havayolu şirketinin kabin ekibi çalışanlarına anket çalışması uygulanmıştır. Çalışmanın sonuçlarına göre; gençlerin tükenmişlik düzeylerinin daha fazla olduğu, yaş ilerledikçe çalışanların duygusal tükenme, duyarsızlaşma ve düşük kişisel başarı düzeylerinin azaldığı görülmektedir. Evli olan ve de çocuk sahibi olan işgörenlerin beklenenin aksine tükenmişlik alt boyutları anlamında etkilenmedikleri görülmektedir. Çalışma statüsü ile tükenmişlik alt boyutları arasında anlamlı bir ilişki olduğu saptanmıştır.

This study explores the factors of corporate social responsibility (CSR) for employees affecting organizational commitment, and then measures the impact of CSR for employees to organizational commitment. The study was conducted by surveying 200 employees working for companies in Ho Chi Minh City. The results of the correlation analysis show that CSR for employees influences the organizational commitment. In addition, the regression analysis shows that more specific results such as job autonomy, benefits (the most influential factor) have positive impacts on “affective commitment” of Vietnamese employees. For “continuance commitment” , besides job autonomy, benefits, the factor “training and development” also shows a positive influence. Meanwhile, the factors related to health and safety, the balance between job and life are not as effective as those in other countries

Published: August 2021

Java lemongrass is commonly cultivated in Vietnam for the use in industries and traditional medicine. Currently, the application of fertilizer, especially nitrogen fertilizer, is one of the most traditional farm practices to increase production yield. A single factorial experiment was carried out in a completely randomized design, three replications to determine the suitability of nitrogen fertilizer rates on growth, leaf and oil yields of Java lemongrass. Six treatments were used in this experiment including 90, 120, 150, 180, 210, 240 kg N/ha and applying 90 kg N/ha as control. Fertilizer base for treatments (for 1 ha) included 20 tons of cow dung compost, 60 kg P2O5 and 60 kg K2O. The application of 120 kg N/ha significantly improved the growth of Java lemongrass as plant height (97.0 cm/plant), average number of leaves (197.1 leaves/plant), average weight of leaves per plant (198.7 g/plant), fully leaf yield (9.4 tons/ha/2 harvest times), essential oil content (1.0% FW) and economic oil yield (97.8 kg/ha/2 harvests).

The study was carried out to determine the distribution and presence of versicular-arbuscular mycorrhiza (VAM) fungi in rhizosphere soil and roots of Da Xanh pummelo in Phu My town, Ba Ria Vung Tau province. The rhizosphere soil and root samples were collected from 6 - 7 years old pummelo of two main soil types, on two soil layers at depths of 0 - 20 cm and 20 - 40 cm, at 2/3 and the edge of canopy. The results showed that the presence of VAM spore density was higher in red basaltic soil (ferralsols) than black soil (luvisols), and common exist on the topsoil layer (0 - 20 cm) as well as the edge of canopy. Glomus and Acaulospora were two most abundant genera in survey areas, and the proportion of mycorrhizal spores ranged from 53.18 ± 2.59% to 58.54 ± 0.46 and from 23.68 ± 2.96% to 29.33 ± 0.64%, respectively. Increasing the soil depth negatively affected on spore density of VAM fungi. The VAM fungi composition aslo changed with soil depth. The percentage of root colonization by VAM fungi ranged from 56.20 ± 3.11% to 62.00 ± 3.37%, and the highest percentage of root colonization by VAM fungi was detected in red basaltic soil.
