Authors: Ahmad Jawad , Aslam Fahid , Zaid Osama , Alyousef Rayed , Alabduljabbar Hisham , Manan Aneel
Published: February 2021

Self-Consolidating Concrete (SCC) has also brittle characteristics. This is unacceptable for any construction industry. The addition of fibers is one of the most common methods to enhance the tensile strength of concrete. Fiber controls the cracking phenomena and enhances the energy absorption capability of the concrete. On the other hand, the addition of fibers has a negative impact on the workability of fresh concrete. In this paper, a detailed study on the influence of Propylene fibers (PP) on the fresh properties of SCC was carried out. PFs were added into concrete mixes in a proportion of 1.0%, 2.0%, 3.0%, and 4.0% by weight of cement to offset its undesirable brittle nature and enhance its tensile strength. The fresh characteristics were evaluated based on its passing ability, flowability using, Slump flow, Slump T50 Spread time, L-Box and V-funnel tests as well as mechanical performance (compressive and split tensile strength) were also evaluated at 7,14 and 28 days curing. Test results indicate that the passing and filling ability decreased as the substitution ratio of PP increased. Besides, the test result indicates that strength was increased up to 2.0% addition of PP and then decrease gradually.
Statistical Considerations on Political Responsivity in Italy Analyzed Over the 70-Year Time Period from 1948 to 2018
Authors: Cirillo Matteo
Published: February 2021

The time evolution of the response of electors to political life is analyzed for the Italian Republic over a 70-year span in which 18 political elections have taken place. The basis for the performed analyses is the official data available from the Italian Ministry of Interiors exposing the results of the political elections from 1948 until 2018. The attention is concentrated on parameters providing information on the responsivity of the electors to country’s political life. These parameters, expressed in adequate percentages, are the effective number of voters and the percentage of these expressing blank or spoilt ballots. The time dependence of these parameters, over the analyzed period, shows regularities, correlations, and interesting peculiarities. The analysis concerns the results for both Chamber of Deputies and Chamber of Senators available, for each election, all along the 70-year time span that are those relative to people voting on the national territory. The results demonstrate that percentages of blank and spoilt ballots represent useful parameters to trace the responsivity of electors. Hypotheses for explaining the results obtained from the statistical analyses are presented both at technical and socio-political level.
Acupuncture and oxytocinergic system: The promising treatment for autism
Authors: Su Tangfeng , Pei Lei
Published: February 2021

Autism spectrum disorder (ASD) is a group of heterogeneous neurodevelopmental disorders characterized by impairments activities without efficient pharmacological therapies in social interaction, speech and stereotypic patterns. Clinical studies have shown the efficacy of acupuncture as an alternative therapy for autism. The effectiveness of acupuncture as an alternative treatment for autism has been demonstrated through clinical trials. However, the molecular mechanisms that underlie these effects remain unclear. Due to its profound pro-social, anxiolytic, stress management effects, and its potential use for the treatment of psychiatric disorders associated with altered socioemotional competence, oxytocin (OT) released from the hypothalamus has attracted considerable interest. In the past decade, a number of clinical and animal studies have shown that OT administration effectively reduces core symptoms of ASD, especially social behavior deficits. Recently, the endocannabinoid system has emerged as a promising target for the treatment of autism. OT was found to facilitate the endocannabinoid-mediated social reward processes in the nucleus accumbens of the mouse brain. Furthermore, serotonin and dopamine are involved in the reward response mediated by OT. In view of these findings, we conclude that acupuncture may produce therapeutic effects on autism by triggering the hypothalamic oxytocin system, which in turn activates the release of neurotransmitters such as endocannabinoids, dopamine and serotonin. This would be a valuable guide for further research on the mechanism of treatment of autism with acupuncture.

Der Beitrag untersucht Möglichkeiten und Strategien zur Vermeidung von Bilanzpublizität. Dabei wird sich zeigen, dass durch Konzernierung, geschickte Gestaltung der Gewinnausschüttungspolitik und Ausnutzung von Wahlrechten zur Publizitätsvermeidung relativ weitgehend für Dritte der Einblick in den Jahresabschluss versperrt wird. Deutlich wird aber auch, dass das Informationsrecht der Gesellschafter den Publizitätsverlust nicht vollständig kompensieren kann.
The Concepts of Truth and Fairness in Thai Criminal Procedure
Authors: Chitov Alexandre
Published: February 2021

This study looks at the principles that shape the structure of the whole of Thai criminal procedure law. It examines how the search for truth is attempted to be reconciled with the idea of a fair trial or procedural fairness. The conflict between the search for truth on the one hand and guaranteeing procedural rights of the accused on the other is particularly problematic in the Thai context. Thai law affirms that some evidence cannot be admissible if it is obtained by a violation of certain procedural norms. At the same time, the law allows judges to admit some unlawfully obtained evidence in the interest of justice. The conflict between various legal norms cannot be solved without permitting judges to exercise broad discretion in striking the right balance between discovering the true facts and protecting the rights of the accused. Thai legal education and practice does not allow a broad judicial discretion in accepting or rejecting evidence on the grounds that it was obtained unlawfully. As a result, there is an attempt to build a sophisticated system of rules to accommodate the interests of justice and fairness in different situations. This system, however, lacks clarity and consistency.
Staatshaftungsrechtliche Implikationen des Wirecard-Skandals
Authors: Renner Moritz
Published: February 2021

Im Zusammenhang mit dem Wirecard-Skandal sind die deutschen Aufsichtsbehörden in die Kritik geraten. Das deutsche System der behördlichen Bilanzkontrolle hat sich als weitgehend dysfunktional erwiesen. Insbesondere vor dem Hintergrund unionsrechtlicher Vorgaben können deshalb Staatshaftungsansprüche geschädigter Anleger bestehen. Neben Ansprüchen unmittelbar gegen die BaFin kommt eine Haftung der Bundesrepublik Deutschland sowohl für die fehlerhafte Umsetzung der Transparenz-RL durch den Bundesgesetzgeber als auch für Versäumnisse seitens der Bundesregierung, der BaFin und der Deutschen Prüfstelle für Rechnungslegung e. V. in Betracht.

Authors: Rahmawati Nur
Published: February 2021

Abstract. This researcher aims to map and analyze the customer loyalty and satisfaction of Antam's Precious Metal (LM) products through four categories of the Kano model. These include one dimensional or performance needs, must be or basic needs, attractive or excitement needs, and indifferent needs. This is a qualitative research with data obtained from interviews, observation and documentation. The study shows that the value of customer loyalty and satisfaction in Precious Metal products, referring to the Kano model analysis, is included in the one-dimensional or performance requirements. Here, the level of satisfaction is directly proportional to the performance attributes. This means that the performance attributes can affect the level of customer satisfaction. Pure Gold, as an Antam’s Precious Metal products, is not considered as must-be or basic needs. It is regarded as attractive or excitement needs due to the rapid development of PT. Antam which is strongly influenced by the quality and development of its product attributes, especially the precious metal products. This study proposes the formation of classification of customer satisfaction using the Kano model and customer loyalty so that it provides benefits in terms of the classification of customer satisfaction.Keywords: Loyalty, Satisfaction, Customer, Antam and Kano Model Analysis Abstrak.

Augmented Reality–Assisted Video Laryngoscopy and Simulated Neonatal Intubations: A Pilot Study
Authors: Dias Patricia L. , Greenberg Rachel G. , Goldberg Ronald N. , Fisher Kimberley , Tanaka David T.
Published: February 2021

BACKGROUND:

For novice providers, achieving competency in neonatal intubation is becoming increasingly difficult, possibly because of fewer intubation opportunities. In the present study, we compared intubation outcomes on manikins using direct laryngoscopy (DL), indirect video laryngoscopy (IVL) using a modified disposable blade, and augmented reality–assisted video laryngoscopy (ARVL), a novel technique using smart glasses to project a magnified video of the airway into the intubator’s visual field.

METHODS:

Neonatal intensive care nurses (n = 45) with minimal simulated intubation experience were randomly assigned (n = 15) to the following 3 groups: DL, IVL, and ARVL. All participants completed 5 intubation attempts on a manikin using their assigned modalities and received verbal coaching by a supervisor, who viewed the video while assisting the IVL and ARVL groups. The outcome and time of each attempt were recorded.

RESULTS:

The DL group successfully intubated on 32% of attempts compared to 72% in the IVL group and 71% in the ARVL group (P < .001). The DL group intubated the esophagus on 27% of attempts, whereas there were no esophageal intubations in either the IVL or ARVL groups (P < .001). The median (interquartile range) time to intubate in the DL group was 35.6 (22.9–58.0) seconds, compared to 21.6 (13.9–31.9) seconds in the IVL group and 20.7 (13.2–36.5) seconds in the ARVL group (P < .001).

CONCLUSIONS:

Simulated intubation success of neonatal intensive care nurses was significantly improved by using either IVL or ARVL compared to DL. Future prospective studies are needed to explore the potential benefits of this technology when used in real patients.

Published: February 2021

OBJECTIVES:

We pursued the use of regional analgesia (RA) to minimize the use of postoperative opioids. Our aim was to increase the use of postoperative RA for eligible surgical procedures in the NICU from 0% to 80% by June 30, 2019.

METHODS:

A multidisciplinary team determined the eligibility criteria, developed an extensive process map, implemented comprehensive education, and a structured process for communication of postoperative pain management plans. Daily pain team rounds provided an opportunity for collaborative comanagement. An additional 30 minutes for catheter placement was added in operating room (OR) scheduling so that it would not affect the surgeon OR time.

RESULTS:

There were 21 eligible surgeries in the baseline period and 34 in the intervention period. In total, 30 of 34 infants in eligible surgeries (88%) received RA. The average total opioid exposure in intravenous morphine milligram equivalents decreased from 5.0 to 1.1 mg/kg in the intervention group. The average time to extubation was 45 hours in the baseline period and 19.9 hours in the intervention group. After interventions, 75% of infants were extubated in the OR, as compared with 10.5% in the baseline period. No difference was seen in postoperative pain scores or postoperative hypothermia between the baseline and intervention groups.

CONCLUSIONS:

We used quality improvement methodology to develop a structured RA program. We demonstrated a significant reduction in opioid requirements and need for mechanical ventilation postoperatively for those infants who received RA. Our findings support safe and effective use of RA, and provide a framework for implementation of a similar program.
Exercise Right Heart Catheterisation in Cardiovascular Diseases: A Guide to Interpretation and Considerations in the Management of Valvular Heart Disease
Authors: Valle Felipe H , Mohammed Basma , Wright Stephen P , Bentley Robert , Fam Neil P , Mak Susanna
Published: February 2021

The use of exercise right heart catheterisation for the assessment of cardiovascular diseases has regained attention recently. Understanding physiologic haemodynamic exercise responses is key for the identification of abnormal haemodynamic patterns. Exercise total pulmonary resistance >3 Wood units identifies a deranged haemodynamic response and when total pulmonary resistance exceeds 3 Wood units, an exercise pulmonary artery wedge pressures/cardiac output slope >2 mmHg/l/min indicates the presence of underlying exercise-induced pulmonary hypertension related to left heart disease. In the evolving field of transcatheter interventions for valvular heart disease, exercise right heart catheterisation may objectively unmask symptoms and underlying haemodynamic abnormalities. Further studies are needed on the use of the procedure to inform the selection of patients who might receive the most benefit from transcatheter interventions for valvular heart diseases.

Published: February 2021

Акутальним в наш час є пошук ефективних акумуляторів сонячної енергії для обігріву приміщень в умовах значного добового перепаду температур. В якості акумулюючого тіла доцільно застосовувати щільний шар гранульованих матеріалів. Вивчено можливість застосування теплообмінного апарату регенеративного типу з гранульованою насадкою у вигляді щільного шару. Нагрівання гранульованої насадки здійснюється потоком повітря з внутрішнього простору. Проектований регенератор призначений для підтримки необхідного температурного рівня. Ідея створення ґрунтового регенератора ґрунтується на відомостях про інтенсивність нагріву повітря в теплиці від сонячного випромінювання в денний час і ефективності контактного теплообміну між повітрям і шаром частинок. Пропоноване схемне рішення передбачає забір повітря з верхньої частини теплиці, що забезпечує подачу потоку повітря в канал при максимальній температурі. Розглядається застосування щільного шару щебню в якості теплообмінної насадки. Представлені результати теплового розрахунку регенератора, проведені для теплиці з площею основи 18 м2. Кліматичні умови відповідають регіонам з помірним кліматом, наприклад, Одеській області. Для середнього рівня інсоляції, характерного для квітня, і заданої тривалості нагріву шару, визначені основні геометричні характеристики теплообмінних каналів. Наведено результати попереднього розрахунку теплових втрат від теплиці в нічний час і час, протягом якого теплота, акумульована регенератором, буде йти на обігрів внутрішнього обсягу теплиці. Отримано, що акумульована теплота дозволяє підтримувати допустиму температуру в теплиці протягом 2,5 години без застосування інших засобів обігріву. При підвищенні температури навколишнього середовища час роботи регенератора буде збільшуватися, що сприяє більшому зниженню енергетичних витрат на підтримку клімату в теплиці
Prognostic value of atrial fibrillation in patients with heart failure and different left ventricular ejection fraction: results of the multicenter RIF-CHF register
Authors: Zhirov I. V. , Safronova N. V. , Osmolovskaya Yu. F. , Тereschenko S. N.
Published: February 2021

Heart failure (HF) and atrial fibrillation (AF) are the most common cardiovascular conditions in clinical practice and frequently coexist. The number of patients with HF and AF is increasing every year.

Aim. To analyze the effect of clinical course and management of HF and AF on the outcomes.

Material and methods. The data of 1,003 patients from the first Russian register of patients with HF and AF (RIF-CHF) were analyzed. The endpoints included hospitalization due to decompensated HF, cardiovascular mortality, thromboembolic events, and major bleeding. Predictors of unfavorable outcomes were analyzed separately for patients with HF with preserved ejection fraction (AF+HFpEF), mid-range ejection fraction (AF+HFmrEF), and reduced ejection fraction (AF+HFrEF).

Results. Among all patients with HF, 39% had HFpEF, 15% — HFmrEF, and 46% — HFrEF. A total of 57,2% of patients were rehospitalized due to decompensated HF within one year. Hospitalization risk was the highest for HFmrEF patients (66%, p=0,017). Reduced ejection fraction was associated with the increased risk of cardiovascular mortality (15,5% vs 5,4% in other groups, p<0,001) but not ischemic stroke (2,4% vs 3%, p=0,776). Patients with HFpEF had lower risk to achieve the composite endpoint (stroke+MI+cardiovascular death) as compared to patients with HFmrEF and HFrEF (12,7% vs 22% and 25,5%, p<0,001). Regression logistic analysis revealed that factors such as demographic characteristics, disease severity, and selected therapy had different effects on the risk of unfavorable outcomes depending on ejection fraction group.

Conclusion. Each group of patients with different ejection fractions is characterized by its own pattern of factors associated with unfavorable outcomes. The demographic and clinical characteristics of patients with mid-range ejection fraction demonstrate that these patients need to be studied as a separate cohort.

ABSTRACT Objectives: the surgical approach persists as the main treatment for esophageal cancer. This study compares the patients of the same institution over time at three different times. Methods: this is a retrospective, observational, descriptive study comparing the surgical outcomes obtained by the Division of Surgical Oncology of Erasto Gaertner Hospital. The sample was divided into Period 1 (1987-1997), Period 2 (1998-2003) and Period 3 (2007-2015). Survival rates and disease-free survival were estimated by the Kaplan-Maier method. Survival predictors were identified with Cox regression. ANOVA test was used for comparison between groups. Data were analyzed with SPSS 25.0 and STATA 16, and p<0.05 was considered statistically significant. Results: a total of 335 patients underwent esophagectomy or esophagogastrectomy. When the clinical characteristics of the 3 groups were compared, there was no statistically significant difference. Neoadjuvance was significantly higher in Period 3 (55.4% of patients). We found a histological change in the diagnosis over time, with a significant increase in adenocarcinoma. Morbidity and mortality rates were higher in Period 3. The main complications were pulmonary and anastomotic fistulas. Overall survival in 5 years increased over time, reaching 59.7% in Period 3. Conclusions: better neoadjuvant treatment contributed to increase the global survival of patients, despite greater rate of immediate complications to surgery.

Published: February 2021

ABSTRACT Objective: To evaluate the impact of the severity of degenerative lumbar disease (DLD) on the occurrence of spinal deformity, as well as on the choice of treatment, whether conservative or surgical. Methods: This is a retrospective analysis of a prospective database. One hundred and thirty patients with low back pain and/or pain radiating to the lower limbs were included in the study and were graded on a DLD scale that considers total spine (panoramic) X-ray findings. The rates of adult spinal deformity (ASD) for the different degrees of the DLD scale were compared using the Chi-square test. The choice of treatment type, conservative or surgical, was also compared among the degrees of the DLD scale using Fisher's exact test. Results: The ASD rate was zero in grade 0 patients, 24% in grade I, 35% in grade II and 44% in grade III (P = 0.02). Grade III patients were more likely to be diagnosed with ASD (OR = 2.22; P <0.05; 95% CI = 0.90-5.45) compared to the other DLD grades. Only 7.7% of the patients were chosen for surgical treatment and there was no difference by the DLD scale grade. Conclusion: There was correlation between the DLD grading scale and the occurrence of ASD, with at least twice the chance of this diagnosis in DLD scale grade III as compared to the other grades. The treatment of choice was conservative in a very small number of patients analyzed, with no difference between the different grades of the DLD grading scale.

Published: February 2021

ABSTRACT Objective: To verify the effectiveness of indirect decompression after lateral access fusion in patients with high pelvic incidence. Methods: A retrospective, non-comparative, non-randomized analysis of 22 patients with high pelvic incidence who underwent lateral access fusion, 11 of whom were male and 11 female, with a mean age of 63 years (52-74), was conducted. Magnetic resonance exams were performed within one year after surgery. The cross-sectional area of the thecal sac, anterior and posterior disc heights, and bilateral foramen heights, measured pre- and postoperatively in axial and sagittal magnetic resonance images, were analyzed. The sagittal alignment parameters were measured using simple radiographs. The clinical results were evaluated using the ODI and VAS (back and lower limbs) questionnaires. Results: In all cases, the technique was performed successfully without neural complications. The mean cross-sectional area increased from 126.5 mm preoperatively to 174.3 mm postoperatively. The mean anterior disc height increased from 9.4 mm preoperatively to 12.8 mm postoperatively, while the posterior disc height increased from 6.3 mm preoperatively to 8.1 mm postoperatively. The mean height of the right foramen increased from 157.3 mm in the preoperative period to 171.2 mm in the postoperative period and that of the left foramen increased from 139.3 mm in the preoperative to 158.9 mm in the postoperative. Conclusions: This technique is capable of correcting misalignment in spinal deformity, achieving fusion and promoting the decompression of neural elements. Level of evidence III; Retrospective study.

ABSTRACT Objective: In Brazil, there are no studies comparing endoscopic treatment of lumbar disc herniation with the conventional open technique in SUS (Unified Health System) with regard to hospitalization time and complications occurring within one year, which is the objective of this study. Methods: A survey of 32 surgeries performed in 2019 (11 open and 21 endoscopic) to evaluate pain parameters before and after surgery (VAS), days of hospitalization, and complications. The data were submitted to statistical analysis (ANOVA) using the Kruskal-Wallis test. Results: Fourteen patients were female and eighteen were male, with a mean age of 41.35 years (p> 0.05 between sexes). The pre- and postoperative VAS for pain radiating to the lower limb were similar between the groups: 8.5 ± 0.82 with the open technique and 8.19 ± 1.15 with endoscopic technique. In both groups there was an improvement in the pain pattern with a significant reduction in the VAS (p < 0.05) and there was no statistical relevance between the groups in terms of pain improvement. There was statistical relevance between the groups in the comparison of days of hospitalization required, with the group submitted to endoscopic surgery having a lower number of days. The complications reported were compatible with those found in the literature (postoperative dysesthesia, new herniation). Conclusions: The endoscopic technique resulted in an important reduction in the number of days of hospitalization, a factor with a high impact on the costs of any surgical procedure, which can be a determining factor in the feasibility of minimally invasive techniques.

Two-facility Location Games with Minimum Distance Requirement
Authors: Xu Xinping , Li Bo , Li Minming , Duan Lingjie
Published: February 2021

We study the mechanism design problem of a social planner for locating two facilities on a line interval [0, 1], where a set of n strategic agents report their locations and a mechanism determines the locations of the two facilities. We consider the requirement of a minimum distance 0 ≤ d ≤ 1 between the two facilities. Given the two facilities are heterogeneous, we model the cost/utility of an agent as the sum of his distances to both facilities. In the heterogeneous two-facility location game to minimize the social cost, we show that the optimal solution can be computed in polynomial time and prove that carefully choosing one optimal solution as output is strategyproof. We also design a strategyproof mechanism minimizing the maximum cost. Given the two facilities are homogeneous, we model the cost/utility of an agent as his distance to the closer facility. In the homogeneous two-facility location game for minimizing the social cost, we show that any deterministic strategyproof mechanism has unbounded approximation ratio. Moreover, in the obnoxious heterogeneous two-facility location game for maximizing the social utility, we propose new deterministic group strategyproof mechanisms with provable approximation ratios and establish a lower bound (7 − d)/6 for any deterministic strategyproof mechanism. We also design a strategyproof mechanism maximizing the minimum utility. In the obnoxious homogeneous two-facility location game for maximizing the social utility, we propose deterministic group strategyproof mechanisms with provable approximation ratios and establish a lower bound 4/3. Besides, in the two-facility location game with triple-preference, where each facility may be favorable, obnoxious, indifferent for any agent, we further motivate agents to report both their locations and preferences towards the two facilities truthfully, and design a deterministic group strategyproof mechanism with an approximation ratio 4.
Deliberative Democracy in Higher Education: The Role of Critical Spaces Across Universities
Authors: Mourad Roger
Published: February 2021

The capacity of democracies to serve as venues for the free expression of ideas and opinions has become threatened by discourse and debate in the global media that is ill-informed and unjustified while human suffering and inequities continue to plague the planet.  This situation calls for scholars and universities to take greater initiative on behalf of the social good beyond the ivory tower.  To this end, the application of deliberative democracy as a method for critical spaces in and across universities is explored.  Such spaces would harness the potential of scholarship for social change by explicitly considering both multi-disciplinary knowledge and values to address global problems and counter neoliberal trends in higher education and societies generally.A theoretical model for scholarly deliberation in critical spaces is elaborated in four stages, culminating in the advancement of proposals for social change to the public sphere.

Authors: Montenegro-Pazmiño Eliana Carolina , Delgado Byron , León José
Published: February 2021

La reintroducción de una especie a su hábitat natural es un proceso a largo plazo, que involucra varios factores, ecológicos y sociales. Su éxito depende en gran medida de las relaciones que se establecen entre todos los actores involucrados, incluyendo a ONGs, autoridades y comunidades locales. La educación ambiental constituye una herramienta clave para generar vínculos entre las organizaciones, tanto públicas como privadas, y las comunidades locales. En este artículo presentamos un estudio de caso del proceso de educación ambiental en torno al proyecto de reintroducción del Guacamayo Verde Mayor en la reserva Ayampe, provincia de Manabí, Ecuador. Analizamos el proceso desde sus alcances, perspectivas, metas, temas y espacios, y lo relacionamos con los objetivos vinculados a la conservación del Guacamayo Verde Mayor en el largo plazo, así como a la apropiación de este tipo de actividades por parte de las comunidades y actores locales, hacia actitudes más responsables con la biodiversidad y el entorno natural.
Entre abordajes sistémicos, racionalistas y estratégicos: una revisión de estudios sobre problemáticas y políticas ambientales en América Latina
Authors: Figueroa Lucas M. , Azerrat Juan Martin
Published: February 2021

El presente artículo tiene como objetivo hacer un aporte metodológico al estudio de las interacciones diversas y heterogéneas entre el ambiente y la sociedad, desde la Ciencia Política. Partimos de la premisa de que los distintos enfoques para el estudio de temas socioambientales, si bien son variados y se basan en teorías diversas, generalmente no visualizan sus características teóricas explicativas. Esa situación dificulta el diálogo metodológico entre ellos y plantea una dificultad para sintetizar abordajes heterogéneos. Frente a ello, buscamos ordenar teóricamente los principales abordajes de la Ciencia Política (sistémico, racionalista e intencional-estratégico), describiendo sus características más importantes. Luego, enraizamos esos enfoques empíricamente desde las corrientes explicativas que trabajan los fenómenos sociales producto de la relación entre el ambiente y la sociedad y los sintetizamos con una mirada integradora. Proponemos tres tipos ideales dinámicos para integrar el abordaje de las problemáticas socioambientales, abriendo una agenda futura para profundizar en la metodología de estudio de la política ambiental, principalmente de América Latina.
Towards a fair hearing for all employees: A case of probationary employee's in Kenya and the right to be heard prior to dismissal
Authors: Gathongo Johana K
Published: February 2021

An employer may require a newly hired employee to serve a reasonable period of probation to establish whether or not his or her performance is of an acceptable standard before permanently engaging the employee. Even so, the current provisions relating to termination of probationary employees under the Employment Act, 2007 (EA) remains a source of concern. Currently, an employer may terminate the employment of a probationary employee at will and without affording such employee an opportunity to be heard. The status quo has received firm approval by the Employment and Labour Relations Court accentuating that employers are immune from claims of unfair termination of a probationary employee. This article argues that for termination to be considered procedurally fair whether during a probation period or not, it should be preceded by an opportunity for an employee to state a case in response to the charges levelled against him or her. This article highlights that all laws in Kenya, including the EA are subject to the Constitution, particularly article 41(1) of the Constitution which guarantees “every person” the right to fair labour practice. Equally, article 27 of the Constitution states that everyone is equal before the law and has a right to equal protection and benefit of the law. Allowing employers’ the freedom to terminate employment without following due process certainly open up the floodgates for abuse of the primary purpose of probation. The mere fact that a contract of employment is labelled as “probationary contract” should not be used as a licence by employers to erode the constitutionally entrenched labour rights. The primary purpose of any good law is to advance the achievement of equity and fairness at the workplace. This can only be achieved by protecting vulnerable and marginalised employees such as probationary employees who participate in unpredictable forms of employment. This article maintains that prominence should be on the existence of an employment relationship and fair labour practice as opposed to the existence of a conditional contract of employment. The existence of an employment relationship should serve as the main “port of entry” through which all employees access the rights and protection guaranteed by labour legislation.
