Authors: Mustafa Hamid Hussein
Published: March 2024

The criteria for measuring the administrative performance to which the individual is attributed and therefore compared to judge him, or the levels in which the performance is considered good and satisfactory, and that defining these standards is necessary for the success of the performance evaluation process, as it helps to define the employees of what is required of them regarding the achievement of the goals of the sports institution And directing managers to the matters that should be taken into account to develop performance, and these standards must be formulated with participation, which helps to raise the degree of their work performance and their loyalty to the institution to which they belong. The standard, regardless of its quality, is required to be accurate in expressing the performance to be measured, and the standard will be like this if it is distinguished by the following characteristics: - 1. Validity of the scale: That is, the factors included in the scale must express those characteristics required by the performance of the work without increasing or decreasing. 2. Stability of scale: It means that the results of an individual's actions through the scale are stable when his performance is stable, but when the measurement results differ according to different degrees or levels of his performance, this is not a defect in it but rather a natural condition. 3. Discrimination: We mean by it the degree of sensitivity of the scale by showing differences in levels of performance, no matter how minor, so that it distinguishes between the performance of an individual or a group of individuals. 4. Ease of use of the scale: We mean by it the clarity of the scale and the possibility of using it by the heads at work. This is what the current research provided with its conclusions that identified the criteria for the performance of the financial secretary of the sports institution, and the recommendations he presented, most notably the use of current research criteria for the purpose of selecting and electing financial secretaries in the administrative body of the Sports Federation (central and sub), as well as attracting people with distinguished skills, and preparing experts Distinguished students and funds from within the sports institution to obtain knowledge and expertise for the development of sports performance.

Published: March 2024

The psychological problems that an athlete is exposed to during training and competition are very many, which can negatively affect his behavior. Psychological hardness is the basic element in the process of sports achievement. Therefore, workers in the fields of physical education and sports sciences must benefit from all the influences that affect human behavior. And the degree of its severity so that we can find appropriate solutions to it, and the mental hardness variable is one of the psychological variables that contribute to the individual's ability to confront the most positive pressures, solve them and prevent future difficulties, as it is a general characteristic of the personality that works on forming and developing the environmental experiences surrounding the individual since childhood. The sports field is considered a fertile source for the growth of the dimensions of mental toughness through the performance of many tasks and duties that require the training requirements to be carried out and which need a great deal of control over things. It is worth noting that the dimensions of psychological hardness we find in a state of continuous growth with age, and the entry of individuals into Continuously rich and varied life experiences help the growth of these dimensions, as the weightlifting game for people with disabilities is a game It has a special character that needs a high concentration because of its danger during the lifting process, as well as the performance requires a strong focus and high psychological toughness for the stability of performance and achievement of it. Hence the importance of research in investigation and identification of the effect of psychological toughness on weightlifting lifters and its effect on achievement.

An investigation of the electrochemical behaviour of Ni-Ti alloy when exposed to artificial blood plasma (ABP) in the presence of 0.1 and 0.5 ppm of Trigonella foenum graecum (TFG) seeds for 1, 10, 20, and 30 days. Studies on AC impedance and polarisation have shown that a protective coating forms on the metal surface while inhibiting corrosion. The protective film has formed on the Ni-Ti implant alloy surface, the linear polarization resistance increased (LPR), and the corrosion current value (Icorr) decreased. The charge transfer resistant value (Rct) and impedance value increase and the double-layer capacitance value decrease.The protective layers morphology and the elemental composition were analyzed by SEM/EDAX. The property of the protective film on the Ni-Ti alloy has been examined by atomic force microscope. The X-ray diffraction analysis has confirmed the nature of the apatite. The corrosion inhibition efficiency of Ni-Ti alloy in ABP in the presence of TFG seeds at various concentrations for different times was improved and protected.

Published: March 2024

La pandémie de coronavirus a largement influencé la participation des peuples
autochtones au sein de l’Organisation des Nations Unies. Les sessions de l’Instance
permanente sur les questions autochtones ont alors eu lieu à distance, ce qui a fortement
diminué la participation des organisations autochtones au profit des États membres en 2021.
Des obstacles technologiques mais aussi d’ordres organisationnels ont rendu difficile
l’intervention de nombreux Autochtones. Pourtant cette baisse de la participation ne s’est
pas traduite par un déclin de la mobilisation. Au contraire, les peuples autochtones dans le
monde entier sont parvenus à contourner les difficultés afin de développer leurs réseaux et
renforcer leur action. Ainsi, on peut voir apparaître de nouvelles formes de solidarité au
sein des populations, que ce soit grâce à l’usage du numérique − qui augmente la visibilité

Refining the resolution of the yeast genotype-phenotype map using single-cell RNA-sequencing
Authors: N’Guessan Arnaud , Tong Wen Yuan , Heydari Hamed , Nguyen Ba Alex N
Published: March 2024

Genotype-phenotype mapping (GPM) or the association of trait variation to genetic variation has been a long-lasting problem in biology. The existing approaches to this problem allowed researchers to partially understand within- and between-species variation as well as the emergence or evolution of phenotypes. However, traditional GPM methods typically ignore the transcriptome or have low statistical power due to challenges related to dataset scale. Thus, it is not clear to what extent selection modulates transcriptomes and whether cis- or trans-regulatory elements are more important. To overcome these challenges, we leveraged the cost efficiency and scalability of single-cell RNA sequencing (scRNA-seq) by collecting data from 18,233 yeast cells from 4,489 segregants of a cross between the laboratory strain BY4741 and the vineyard strain RM11-1a. More precisely, we performed eQTL mapping with the scRNA-seq data to identify single-cell eQTL (sc-eQTL) and transcriptome variation patterns associated to fitness variation inferred from the segregants’ bulk fitness assay. Due to the larger scale of our dataset, we were able to recapitulate results from decades of work in GPM from yeast bulk assays while revealing new associations between phenotypic and transcriptomic variations. The multidimensionality of this dataset also allowed us to measure phenotype and expression heritability and partition the variance of cell fitness into genotype and expression components to highlight selective pressure at both levels. Altogether these results suggest that integrating large-scale scRNA-seq data into GPM improves our understanding of trait variation in the context of transcriptomic regulation.

Pharmacological Effects and Uses

Epothilones represent a novel class of anticancer drugs which inhibit the cell cycle by interfering with microtubules. Their chemical and pharmacological properties as well as several synthetic approaches to some of the natural compounds are described.

First results from clinical trials with natural epothilones as well as novel derivatives are promising indicating that epothilones have the potential to become a cornerstone in future cancer therapy.
Schema‐driven source misattribution errors: remembering the expected from a witnessed event
Authors: Kleider Heather M. , Pezdek Kathy , Goldinger Stephen D. , Kirk Alice
Published: April 2007

When recollection is difficult, people may use schematic processing to enhance memory. Two experiments showed that a delay between witnessing and recalling a visual sequence increases schematic processing, resulting in stereotypic memory errors. Participants watched a slide show of a man and a woman performing stereotype‐consistent and stereotype‐inconsistent actions, followed by an immediate or delayed memory test. Over a two‐day delay, stereotype‐inconsistent actions were increasingly misremembered as having been performed by the stereotype‐consistent actor (Experiment 1). All the source errors increased, regardless of stereotype consistency, when the wrong actor was suggested. When we merely suggested that ‘someone’ performed an action (Experiment 2), only stereotype‐consistent source errors were increased. Although visual scenes are typically well remembered, these results suggest that when memory fades, reliance on schemata increases, leading to increased stereotypic memory errors.

Mesoporous Silica Nanoparticles for Drug Delivery and Biosensing Applications
Authors: Slowing I. I. , Trewyn B. G. , Giri S. , Lin V. S.‐Y.
Published: April 2007

Recent advancements in morphology control and surface functionalization of mesoporous silica nanoparticles (MSNs) have enhanced the biocompatibility of these materials with high surface areas and pore volumes. Several recent reports have demonstrated that the MSNs can be efficiently internalized by animal and plant cells. The functionalization of MSNs with organic moieties or other nanostructures brings controlled release and molecular recognition capabilities to these mesoporous materials for drug/gene delivery and sensing applications, respectively. Herein, we review recent research progress on the design of functional MSN materials with various mechanisms of controlled release, along with the ability to achieve zero release in the absence of stimuli, and the introduction of new characteristics to enable the use of nonselective molecules as screens for the construction of highly selective sensor systems.
Encapsulation of Water‐Immiscible Solvents in Polyglutamate/ Polyelectrolyte Nanocontainers
Authors: Teng X. , Shchukin D. G. , Möhwald H.
Published: April 2007

A novel approach for encapsulation of hydrophobic materials into a hydrophilic multifunctional shell is presented, based on combining an ultrasonic technique and a layer‐by‐layer protocol. Polyglutamate/polyethyleneimine (PEI)/polyacrylic acid (PAA) and polyglutamate/PEI/PAA/silver nanocontainers loaded with a hydrophobic dye, 5,10,15,20‐tetraphenylporphin, dissolved in toluene, are fabricated. Uniform, stable, and monodisperse polyglutamate/PEI/PAA nanocontainers of about 600 nm are obtained. The hydrophobic core of the nanocontainers might contain a huge variety of water‐insoluble drugs and the outer polyelectrolyte shell may provide controlled permeability and desired multifunctionality. Confocal fluorescence microscopy and scanning electron microscopy are employed for the characterization of the resulting nanocontainers. Using sodium dodecyl sulfate as surfactant, the amount of nanocontainers, their monodispersity, and stability can be increased dramatically.
Assembly and Photoinduced Organization of Mono‐ and Oligopeptide Molecules Containing an Azobenzene Moiety
Authors: Matsuzawa Y. , Ueki K. , Yoshida M. , Tamaoki N. , Nakamura T. , Sakai H. , Abe M.
Published: April 2007

Assembled systems consisting of an azobenzene moiety as the photofunctional component and valyl units as the network backbone are investigated. The molecular ordering of these assemblies is examined by spectroscopy and theoretical calculations. The number of valyl units greatly influences the molecular order in the organized systems. Only N‐(L‐valyl‐L‐valyl‐L‐valyl)azobenzene‐4‐carboxamide (3) forms a complete β‐sheet structure in this artificial assembly. Upon photoirradiation, the azobenzene moieties isomerize completely, revealing the reversibility in the structural organization through the flexibility of the β‐sheet network in this system.
Ischemic heart disease mortality among miners and other potentially silica‐exposed workers
Authors: Weiner Jan , Barlow Lotti , Sjögren Bengt
Published: April 2007

Background

Some previous studies have observed an increased mortality regarding ischemic heart disease (IHD) among miners and industrial sand workers. The purpose was to study the occurrence of IHD mortality among silica‐exposed workers.

Methods

Male miners, well borers, dressing plant workers, and other mine and stone workers were identified in the Swedish National Census of 1970. The total cohort (n = 11,896) was followed from 1970 until December 31, 1995 and linked to the Cause of Death Register. The referent group comprised all gainfully employed men identified in the same census. The Standardized Mortality Ratio was calculated as the ratio between observed and expected numbers of deaths.

Result

An increased risk due to IHD mortality was observed among miners, well borers, dressing plant workers, and other mine and stone workers.

Conclusion

These results indicate a possible relation between silica‐dust exposure and IHD. The increased risk of IHD mortality is unlikely explained by smoking habits. Shift work might explain some of the increased risk. A low‐grade inflammation in the lungs as a result of dust exposure is discussed as a possible cause. However, the key message is that better dose estimates and better confounding control is needed to study the possible relation between silica‐dust exposure and IHD. Am. J. Ind.

Is the medical community ready for worker notification?
Authors: Rest Kathleen M.
Published: April 2007

Although the potential for early detection of disease has been of central importance in the evolution of worker notification policy and practice, it is not the only positive outcome of medical intervention. The provider‐patient encounter also creates an important opportunity for patient‐centered risk communication that may result in workplace modifications as well as lifestyle changes to reduce the likelihood of subsequent illness and injury—both work and nonwork related. At the same time, it may signal the beginning of a series of social, legal, and political actions that may have positive or negative consequences for notified workers.

This article identifies several important roles for members of the medical community relating to worker and community notification programs and explores the readiness of health care professionals in assuming these roles. It is suggested that health care providers lack both the training and sociopolitical sensitivity needed for meaningful participation in the notification process. This article addresses possible short‐term and long‐term approaches to enhancing the readiness of health care providers and suggests that effective intervention with notified workers requires a willingness to step beyond the confines of the medical model. © 1993 Wiley‐Liss, Inc.
