Talent management: A 'recipe' for public service delivery in the fourth industrial revolution
Authors: Shava Elvin , Doorgapersad Shikha Vyas
Published: January 2022

The article was based on an interpretive paradigm, which adopts a qualitative desktop review approach. Various document sources that inform 4IR and talent management within the local government context in South Africa were employed. The two cities of Johannesburg and Ekurhuleni were used as case studies to examine their talent management strategies in the 4IR. The analysis of documents has shown that the 4IR can enable accelerated delivery of services; increase access to services; improve community participation; and more significant social accountability. Nevertheless, some municipalities in South Africa do not have enough resources and skills capacity to implement ICT/4IR measures to improve services; hence managing talent in key technical jobs has become an impediment. The absence of institutional readiness among local municipalities is a huge deterrent to managing talent needed to drive service delivery in the 4IR. The study concludes that to achieve efficient public service delivery within the 4IR, local municipalities should retain talent to manage the digital technologies that demand skilled expertise. The article recommends the government develop policies that offer guidance to local municipalities on managing specified sets of talents that are deemed crucial to enhancing socio-economic development in the 4IR.

Published: January 2022

Budgetary slack occurs because of the potential difference with the revenue budget target. the difference in potential revenue with the revenue budget target indicates the occurrence of individual behavior lowering the income target to facilitate the achievement of the government budget. The purpose of this study is to empirically prove the effect of budget participation, information asymmetry, and job insecurity that trigger budgetary slack. The population of this research is officials of the Indonesian: Regional Working Unit in the province of East Java, Indonesia. The sampling technique used is proportional sampling, the research respondents were 84 people. The results show that budget participation, information asymmetry, and job insecurity have a positive effect on budgetary slack. The high budget participation of public sector employees can trigger budgetary slack. Information asymmetry motivates budget implementers to take action to reduce revenue targets and increase government spending. High job insecurity in the work environment creates pressure on employees so that budgetary slack is created.
Contextual and multifactorial influence on perception of safety from crime among selected Malaysians

Published: January 2022

Despite official crime figures showing a continuous decline in the rate of crime, the perception of the high level of crime by many Malaysians suggests other factors are affecting their perception of safety from crime. The objective of this study is to identify and understand these factors through a qualitative study that employs online focus group discussions. This study argues that the perception of safety from crime is the result of interactions of a number of factors such as the experience of victimisation, crime information, neighbourhood conditions as well as the perception of law enforcement and government crime reduction policy. The sense of safety from crime is also contextual as it may fluctuate according to time, place, activities and situations. Analysis of the data from the focus group discussions found that participants generally have a high perception of safety from crime. However, participants felt less safe when they were in public places and when interacting with online services. In most circumstances, participants' sense of safety is affected by the pressure to be vigilant and to avoid criminal victimisation. This pressure is exacerbated by low-quality information on crime that is often received through social media. Crime information on social media has a significant impact on participants’ perceptions of crime. The overall analysis of the findings suggests that the most important factor which affects the perception of safety from crime among these selected Malaysians is their sense of safety in their homes and their neighbourhood.  Hence, efforts to increase the sense of safety among Malaysians should focus on this context.

Training on Agro Eco-System Analysis for Cassava Farmers in Plant Pest Organism Management Techniques. Pest population fluctuations in cassava plants tend to increase and spread rapidly in drought fields and a monoculture cropping pattern with close spacing therefore the presence of pests planted is highly dependent on agro-ecosystem conditions. Therefore ecological-based pest control is very necessary.  To maintain the stability of the plant ecosystem, basic skills are needed in conducting agroecosystem analysis (AESA). Based on the analysis results obtained recommendations for appropriate ecosystem management for each growing season and facilitate farmers in determining good cultivation techniques regarding pest control, cropping patterns, soil and water conservation as well as natural enemies that are appropriate for their plants. AESA activities are carried out so that farmers understand and are skilled in managing their cassava plantations because Randotonda Village is a producer of "Nuabosi" cassava which is known as a regional superior product. The activity is carried out in a participatory manner by directly involving the participating farmers as observers, fact seekers and decision-makers for the management of their agroecosystems through discussion and manifesting current real conditions with the hope that in the future they can manage their cropping agroecosystems properly. The highest increase in farmer understanding occurred in natural enemy components of 91.67% while the average increase in farmer understanding for all agro-ecosystem components was 57.14%. All participants were able to perform AESA very well which was indicated by the ability of farmers to make recommendations for managing cassava agroecosystems for the next planting season.

Published: January 2022

Los cementos de activación alcalina (CAA) requieren de un componente alcalino para la activación del precursor. La fabricación del activador alcalino (AA) supone un consumo energético y de materias primas muy importante, de modo que la huella de carbono de los CAA está fundamentalmente influenciada por ese factor. Una alternativa es el uso de otras materias para la preparación del AA. En este trabajo se realiza un exhaustivo análisis de las diferentes alternativas: materias de base silícea para la preparación de silicatos alternativos y materias de base alcalina. Se comparan de forma relativa las huellas de carbono con respecto a cementos Portland comerciales, y se analiza el efecto que tiene la sustitución de reactivos comerciales por activadores alternativos.

‚Schlachtengewitter‘: Kriegs- und Schlachtenlärm in der griechisch-römischen Antike. Eine Skizze zum Beitrag der antiken Militärgeschichte zur „Sensory History“
Authors: Stoll Oliver
Published: January 2022

Kriegslärm und seine Wirkungen auf die ‚Akteure‘ sind für die Antike ein noch ungenutzter Betrachtungsgegenstand. „Sensory History“ darf als innovativer Beitrag zur Geschichtswissenschaft insgesamt gelten. Schlachtbeschreibungen thematisieren Sinneseindrücke aller Art: Die Geräusche des Krieges gehören zu den lautesten, die sich in der Menschheitsgeschichte finden lassen, der Kampf war eine multisensorische Angelegenheit mit Geschrei und Musik. Im Beitrag soll die Aufmerksamkeit auf diese Phänomene und ihre literarische Verarbeitung gelegt werden. Was bedeuteten Geräusche und Eindrücke des Krieges für die Beteiligten? Die in der Antike verbreitete Auffassung, dass „in jeder Schlacht zuerst die Augen erliegen würden“ (Tac. Germ. 43,5), ist zu relativieren! Die Kakophonie der Schlacht blieb nicht ohne Wirkung: sie bedeutete terror und konnte Menschen paralysieren!

The mechanisms of development of nosocomial infectious complications in COVID-19 and the contribution of bacterial and mycotic superinfection to the formation of extremely high mortality among patients with severe and extremely severe course of this disease have not yet been fully revealed. The objective: to study epidemiology, risk factors for the development of nosocomial superinfection, and its effect on the severity and outcome of the disease in patients with COVID-19.Subjects and Methods. 383 cases of severe and extremely severe COVID-19 were retrospectively analyzed. Demographic data, the presence of concomitant diseases, community-acquired co-infection at the time of hospitalization, data on the methods used to treat new coronavirus infection, severity of the course of the disease, developed infectious complications and their etiology, and the disease outcome were studied. Risk factors for the development of secondary infectious complications and the contribution of nosocomial superinfection to the severity of COVID-19 and the disease outcome were evaluated.Results. Risk factors for the development of secondary infectious complications include age over 65 years (OR 1.04; 95% CI 1.03–1.06; p < 0.0001), concomitant cardiovascular pathology (OR 3.82; 95% CI 2.02‒7.19; p < 0.0001), chronic kidney disease, including requiring renal replacement therapy (OR 2.01; 95% CI 1.33–3.02; p = 0.0007), and glucocorticoid therapy (OR 1.62; 95% CI 1.02–2.69; p = 0.04). The development of nosocomial infectious complications in patients with COVID-19 is associated with a more severe course of the disease and unfavorable prognosis (OR 13.44; 95% CI 8.23‒21.92; p < 0.0001).Conclusion. Identification of risk factors for the development of secondary infectious complications in COVID-19 allows developing differentiated approaches to the pathogenetic treatment of patients with severe COVID-19, increasing alertness in terms of the development of nosocomial infections, ensuring their timely diagnosis and treatment.

The objective: to establish the possible effectiveness of exogenous phosphocreatine as a component of pharmacological support during the resuscitation stage of rehabilitation measures in critically ill patients with COVID-19.Subjects and Methods. Within a randomized study, 21 patients diagnosed with COVID-19 were divided into two groups: Group 1 (patients received the infusion of exogenous phosphocreatine as part of intensive care) and Group 2 (patients received standard intensive care) against the background of rehabilitation measures. Patients were assessed for muscle strength using the MRC scale, exercise tolerance by Borg rating, oxygenation parameters, routine clinical laboratory blood tests, dependence on respiratory support, outcome on day 10 of therapy, and hospital outcome.Results. The effectiveness of the use of the exogenous phosphocreatine as a component of pharmacological support during the resuscitation stage of rehabilitation measures in critical patients has been confirmed by positive dynamics: an increase in muscle strength (the MRC score in the group receiving exogenous phosphocreatine on day 10 was 0.5 points higher) and an increase in exercise tolerance (Borg rating in the group receiving exogenous phosphocreatine on day 10 was 1.5 points higher), significant increase in oxygenation based on arterial blood saturation data, and significant increase in lymphocyte count by 25% in the group receiving exogenous phosphocreatine.Conclusion. Exogenous phosphocreatine is a candidate drug for pharmacological support during resuscitation stage of rehabilitation of critical patients with COVID-19.

The objective: to evaluate the effectiveness of neurometabolic therapy in patients with severe course of the new coronavirus infection of COVID-19 complicated by the development of encephalopathy.Subjects and Methods. A pilot prospective study was carried out with the participation of 61 patients with a severe course of COVID-19 complicated by encephalopathy. The patients were randomized into two groups: the study group (n = 34), the patients in which, in contrast to the control group (n = 27), received Cytoflavin in addition to the main therapy in a daily dose of up to 40 ml for 5 days. The dynamics of the general and neurological status was assessed on days 3‒4 and 6‒7 days of treatment using the NEWS (National Early Warning Score), Glasgow coma and ICDSC (Intensive Care Delirium Screening Checklist) scales. Additionally, the blood level of neuron-specific enolase (NSE) was investigated at baseline and on days 6‒7.Results. Patients in most cases were elderly or senile with a high comorbidity index (up to 4 points according to Charlson). The persistence of delirious symptoms correlated with their age and low SpO2 levels. In half of the cases (50.8%), the disease had an unfavorable outcome. In the study group, by the 6‒7th day of treatment, there was a significant positive dynamics of the general condition, assessed by the NEWS scale (p = 0.012), a tendency towards a faster recovery of the overall score on the Glasgow scale (p = 0.083), a tendency towards more rapid regression of delirious symptoms by ICDSC scale (p = 0.055) versus the comparison group.Conclusions. Given the high risk of an unfavorable outcome in patients with a severe course of COVID-19 complicated by the development of encephalopathy, the additional use of Cytoflavin is advisable since it contributes to the regression of the symptoms of encephalopathy and may have a positive effect on the course of the disease.

Introduction. The combination of primary brain injury with cytokine storm and hemodynamic disturbance in septic shock leads to secondary brain damage and growing neurological deficit. Blood purification procedures can be considered as an additional option in the treatment of septic shock in this group of patients.Subjects and Methods. The study included 11 patients after neurosurgical interventions with septic shock and acute kidney injury who underwent continuous renal replacement therapy (CRRT) using membranes with increased adsorption capacity.Results. During CRRT there was a significant regression in severity of multiorgan dysfunction according to SOFA score, a decrease in the requirement for vasopressor support with norepinephrine, and a decrease in lactate blood level. In addition, after the end of the procedure, there was a significant decrease in procalcitonin blood level. Septic shock reversal was observed in 8/11 patients (72.7%). In 3/11 patients, neurological deficits regressed during the procedure.Conclusions. The results indicate the possibility of using CRRT with membranes with increased adsorption capacity in patients after neurosurgical interventions with septic shock. Changes in neurological status can be considered as an additional parameter for the effectiveness of therapy for septic shock in patients with primary brain injury.

The objective: to assess the information value of proadrenomedullin (PAM), once measured upon admission to ICU in predicting mortality and differential diagnosis of septic and hypovolemic shock.Subjects and Methods. A prospective cohort retrospective study was carried out. 134 patients in a state of shock were included in the study. Of these, 125 patients had septic shock; 9 ‒ hypovolemic one. The diagnosis of septic shock was established according to the Sepsis-3 criteria. To compare hypovolemic and septic shock, blood levels of proadrenomedullin (PAM), procalcitonin (PCT) and lactate were tested in 9 patients with obvious hypovolemic shock. Samples (venous blood) were collected within 24 hours from the moment the vasopressors began to be used in ICU or by the ambulance team (EMS).Results. The ROC analysis showed comparable predictive value with APACHE II, SOFA and lactate scales in patients with septic shock with cut-off > 4.23 nmol/L. The range of PAM values in patients with septic shock was Me 4.56 (2.9‒6.7) in patients with hypovolemic shock – Me 0.6 (0.1‒1.4).Conclusion. Proadrenomedullin can be used for differential diagnosis of septic shock and hypovolemic shock. Blood levels greater than 2.9 nmol/L are of absolute value for the diagnosis of septic shock. Procalcitonin is inferior to PAM within the range of 1.0–6.45 ng/ml. PAM unlike SCT is a statistically significant predictor of global outcome in septic shock along with lactate and scales. But such scales as SOFA and ARACНE-II are more laborious in comparison with testing proadrenomedullin blood level.
