Published: September 2023

Job performance is one of the concerns of any organization, as it is one of the critical determinants of its success. Over the past decades, researchers gained much interest in explaining employee performance. This present study aims to contribute to the literature by examining the factors influencing employee performance and the mediating role of work discipline and job satisfaction in the context of higher education organizations. This research employs Social Exchange and organizational commitment theories to build the proposed framework. Data collected through a self-administrative survey at the higher education institution was used in this study. The sample of this research consists of 151 employees, both administrative staff and lecturers. The structural equation modeling results show that organizational commitment, work, and work discipline positively influence employee performance. In contrast, work environment and job satisfaction do not influence employee performance. The result also highlights that the work environment influences discipline, organizational commitment, and environmental job satisfaction. Moreover, the mediating role of job satisfaction and work discipline was found in this study. Furthermore, besides the direction for future research, this work contributes to the literature and organizational practice.

A two component normal mixture alternative to the Fay-Herriot model
Authors: Chakraborty Adrijo , Datta Gauri Sankar , Mandal Abhyuday
Published: September 2023

This article considers a robust hierarchical Bayesian approach to deal with random effects of small area means when some of these effects assume extreme values, resulting in outliers. In the presence of outliers, the standard Fay-Herriot model, used for modeling area-level data, under normality assumptions of random effects may overestimate the random effects variance, thus providing less than ideal shrinkage towards the synthetic regression predictions and inhibiting the borrowing of information. Even a small number of substantive outliers of random effects results in a large estimate of the random effects variance in the Fay-Herriot model, thereby achieving little shrinkage to the synthetic part of the model or little reduction in the posterior variance associated with the regular Bayes estimator for any of the small areas. While the scale mixture of normal distributions with a known mixing distribution for the random effects has been found to be effective in the presence of outliers, the solution depends on the mixing distribution. As a possible alternative solution to the problem, a two-component normal mixture model has been proposed, based on non-informative priors on the model variance parameters, regression coefficients and the mixing probability. Data analysis and simulation studies based on real, simulated and synthetic data show an advantage of the proposed method over the standard Bayesian Fay-Herriot solution derived under normality of random effects.

Tunable bonds
Authors: Rzepa Henry
Published: September 2023

Car transmissions come in two types, ones with fixed ratio gears, and ones which are continuously variable. When it comes to chemical bonds, we tend to think of them as being very much of the first type. Bonds come in fixed ratios; single, aromatic, double, triple, etc. OK, they do vary, but the variations are assumed as small perturbations on the basic form. Take for example the molecule shown below.
The Fine-tuned principle in chemistry

The  so-called  Fine tuned model of the universe asserts that any small change in several of the dimensionless fundamental physical constants would make the universe radically different (and hence one in which life as we know it could not exist). I suggest here that there may be molecules which epitomize the same principle in chemistry. Consider for example dimethyl formamide.

The mysteries of stereoinduction.
Authors: Rzepa Henry
Published: September 2023

Stereo-induction is, lets face it, a subtle phenomenon. The ratio of two stereoisomers formed in a reaction can be detected very accurately by experiment, and when converted to a free energy difference using ΔG = -RT Ln K, this can amount to quite a small value (between 0.5 – 1.5 kcal/mol). Can modelling reproduce effects originating from such small energy differences?

Towards a solution to the problem of safety management of structurally complex systems
Authors: Bochkov Alexander V.
Published: September 2023

The non-isolation of modern, structurally complex, multi-purpose systems implies not only their interaction with the external environment, but also the impact of this environment on the systems themselves. The ability to predict and assess the consequences of these impacts, which are characterised by great uncertainty about the time, place and method of implementation, as well as the choice of a particular object of influence, is a task of extreme urgency in today’s globalised world. If the stability of functioning of any structurally complex system is understood as the achievement by it of the purpose of its functioning with acceptable deviations on the volumes and times of implementation of private tasks, the safety management in this system is reduced, in fact, to minimisation of unplanned losses at the occurrence of abnormal situations of various kinds and to carrying out of measures for their prevention. The success of such tactics depends largely on the effectiveness of the risk management system, on the ability of decision-makers to foresee the possibility of poorly formalised threats turning into significant risks, i.e., on having methods and tools for ranking threats and significant risk factors. Inevitably, there is the task of setting protection priorities, ranking objectives (usually of different types), problems and threats, and reallocating available (usually limited) resources. The article considers the issues involved in building an integral security model that takes into account the risks to the assets being protected.
Statistical analysis of a Tagore song based on Raga Kafi
Authors: Chakraborty Soubhik , Singh Prerna
Published: September 2023

Rabindra Sangeet or Tagore songs encompass a wide variety of human emotions. Most of these songs are based on Hindustani ragas. Kafi is a joyful raga and therefore could be helpful to combat stress. We are motivated to analyse a popular Tagore song, namely, Momo Chitte, which is based on this raga. Statistical analysis compares two phases of 30 s each of a vocal recording of this song. Several statistical features are considered including note duration, inter onset interval, rate of change of pitch, statistical parameterization of melody and rhythm in addition to analysis of spectrogram and pitch profile. The experimental results are encouraging.

Me formé en el campo de las artes escénicas, soy maestra en arte dramático de la Universidad de Antioquia. Luego de mi pregrado, tuve interés por hacer maestría y doctorado, en relación con el actor cómico. Me interesaba el entrenamiento del actor cómico. En nuestra formación no tuvimos acceso al lenguaje de la comedia. Me fui a hacer un doctorado a Barcelona y ahí me enamoré de una escuela de circo, en donde había talleres de clown, del arte del payaso. Empecé a explorar el lenguaje y lo profundicé. Terminé haciendo un doctorado en la Universidad Paris III Sorbonne Nouvelle en Francia. En la Maestría me había concentrado en un viaje a la inversa: no estudié el actor que crea el personaje, sino el clown que surge de la persona misma, de sus defectos, de sus características. En el doctorado propuse desarrollar el enfoque del payaso en Colombia como actor social y político y estudiar cómo la risa es una forma de resistencia y de libertad. Sin embargo, después de la entrega de la tesis, empecé a probar el trabajo teórico y a darme cuenta de cómo funciona eso en la práctica. Fue el inicio de la práctica de investigación-creación que llevo haciendo desde años...

Antes de entrar en el concepto, debo decir que en el contexto de la investigación doctoral yo propuse una metodología de aproximación que se configuró a partir de dos componentes principales. En la primera parte de la tesis básicamente intenté describir qué es esto del Teatro de Creación, cuál es su origen y también explicar por qué traducirlo al español como Teatro de Creación. En la segunda parte desarrollé Teatro de Creación Aplicado. El concepto de Aplicado y cuáles son sus componentes. Y hablo de traducción porque su formulación se remonta a los años 80 y 90 en el contexto anglosajón, bajo la denominación de ‘Devising Theatre’, que, si se intentara una traducción literal, tendría que plantearse como Teatro “creante”, o tal vez mejor, “teatro que crea”. Para ser más preciso en su origen se utilizó el término ‘Devised’, como participio, mientras que a mí me resultó más apropiado utilizar el término en tiempo activo, es decir ‘Devising’. En otras palabras, ‘Devising Theatre’ enfatiza la condición de un teatro creado, creado en equipo, y que además genera creaciones artísticas, sociales, educativas, empresariales o políticas, entre otras, a partir del propio trabajo. Por eso este ‘Devising’...

Chronic kidney disease is a progressive chronic disease of the kidney nephrons that can affect the body's fluid and electrolyte balance. In this condition, permanent kidney replacement is needed, namely kidney transplantation and hemodialysis. Hemodialysis is a therapy that is mostly done by patients. This study aims to determine the differences in creatinine pre and post hemodialysis in chronic kidney disease patients at Arcamanik General Hospital, Bandung City. The data obtained by the 34 patients will be recorded and displayed in the form of data tabulations and analyzed by the Normality Test using the Shapiro-Wilk with normally distributed data obtained, where the pre hemodialysis p value is 0.970 (p> 0.05) and the post hemodialysis p value is 0.530 (p>0.05). The pre hemodialysis creatinine level averaged 12.83 mg/dL, while the post hemodialysis creatinine level averaged 5.17 mg/dL. From the results it can be seen that the creatinine level before hemodialysis is higher than the creatinine level after hemodialysis. Based on the research conducted, it can be concluded that there is a significant difference in the comparison of pre and post hemodialysis creatinine in chronic kidney disease patients after the data is processed statistically using the Paired T-Test, with a p value of 0.001 (p <0.05).

The Finger Grip Relaxation Technique is an easy and simple technique that anyone can do. Its application is related to the fingers and the flow of energy in the body. This relaxation can then heat the entry and exit points of energy in the meridians (body or energy pathways) in the fingers, thereby causing reflex stimulation (spontaneous) when gripping. The finger tapping relaxation technique helps the soul, mind, and body relax. When conditions are relaxed, it triggers the natural release of endorphins, this is the hormone that naturally acts to relieve pain. Writing this proposed scientific article aims to determine the effectiveness of finger grip relaxation techniques in reducing pain intensity in postoperative patients.
This study used a descriptive method with a literature review approach. The data source is secondary. Articles and some magazines serve as sources of information. The literature search strategy uses the PICO framework. The inclusion criteria are national and international research journals that discuss reducing pain intensity in postoperative patients using finger grip relaxation techniques, as well as articles or journals published after 2018 in English and Indonesian. An approach consisting of presentation methods and analytical methods is used for data analysis. The results obtained in this study regarding the effect of hand-held relaxation techniques on reducing pain intensity. Of the five research publications reviewed, all of them are effective in reducing pain using finger grip relaxation techniques. The interventions used were the results of five studies where there was a decrease in pain. This proves that finger-held relaxation techniques can reduce pain intensity in postoperative patients.

Hungary's sheep population is decreasing nowadays. On the first of December 2017, the herd consisted of more than 1.1 million sheep, and by June 2021, this number had barely reached 953 thousand. Based on data from the Central Statistical Office, on December 1, 2020, the sheep population numbered a total of 944 thousand individuals, of which 754 thousand were ewes (HCSO, 2020). Of this, native breeds account for 2.5%, and nearly half of this is accounted for by the Hungarian racka sheep (Hortobágy). This amounts to approximately ten thousand individuals (BODNÁR et al., 2016). For this small number of sheep, it is important to preserve their genetic values and avoiding inbreeding is even more important. This is particularly related to the fact that we need to examine the vitality of the lambs in order to produce even better breeding animals. It is important to monitor the behaviour of the sheep, the course of calving and the mother-lamb relationship, as this is of great importance in the development of technology. The observation of our farm animals influences feeding and husbandry technologies, thus we can create a better environment for them (BODNÁR et al., 2015).

The aim of the preliminary study was to improve success of cryopreservation of stallion spermatozoa. The effect of different equilibration lengths and two techniques for freezing of stallion semen was evaluated, based on motility and viability parameters. Fresh semen was diluted with BotuCrio extender and divided into 3 groups equilibrated for 0.5h, 2h, and 4h. Subsequently, half straws of each group were cryopreserved in the vapours of the liquid nitrogen or in the automatic freezer. Results of stallion spermatozoa motility and progressive motility showed decreasing trend with increased time of equilibration. Moreover, a significant difference (p < 0.05) for the percentage of spermatozoa producing ROS was found between semen frozen in the vapours of the liquid nitrogen compared to semen cryopreserved by the automatic freezer in the same equilibration time. Nevertheless, results of this study are of preliminary character. Experiments using higher number of individuals need to be tested in order to find the best procedure for semen cryopreservation of Slovak national horse breeds.

Determination of the gender in sturgeon is very important in fish farmers, as sex is one of the main factors that determine aim of cultivating them. One of the method for maturation monitoring of sturgeons is steroid hormone analysis. On this base the current study used estradiol and testosterone hormones to determine the gender of 2-3-year-old Siberian sturgeon (Acipenser baerii) cultivated in sturgeon broodstock farm located in the Zhrebchevo Dam lake, Bulgaria. The serum concentrations of circulating reproductive hormones found in the both sex were similar to the hormonal profiles in previously reports. The results were confirmed also by histological examination, which showed pre-vitellogenic stage (Stage I) in female and maturity (Stage V) at the male individuals. The findings indicate the force of current steroid hormones as a method for sex determination. In conclusion, analysis of circulating reproductive hormones may be a useful method in early determining the sex of Siberian sturgeon.
