Transactional and Transformational Leadership Styles on the Effectiveness of Work From Home and Work Productivity
Authors: Kairupan Daniel Joel Immanuel
Published: September 2023

During the work-from-home (WFH) period, employees faced a new situation. Employees are required to adapt to the new situation. Changes in situations and demands and problems from working in the office to working at home, especially during a pandemic, certainly require leaders to show proper leadership behavior. Leaders need to find ways to increase employee work productivity, especially when the WFH work system begins to be implemented. This research was conducted to examine the impact of transactional and transformational leadership on productivity and performance effectiveness during the implementation of remote systems or work-from-home. Researchers chose transactional and transformational leadership because in writing this scientific paper, researchers found many previous articles that raised transactional and transformational leadership types as their research topic, but rarely examined the extent to which transactional and transformational leadership styles affect WFH effectiveness and employee work productivity. This study used a survey method with samples of employees who used remote systems during the Covid-19 pandemic era. Data collection was carried out using an online questionnaire using Google Forms. The statistical tool used to process the data is SPSS Statistics 22. Researchers also hope that the results of this research can become new insights for businesspeople in dealing with changes in the work-from-home system or remote system.

The developmental biology of the okra flea beetle. Podagrica uniforma (Jac.), was studied in the laboratory under ambient conditions (24-28°C, 79-92 % RH: 12 hour photoperiod) and the various life cycle stages were described. Females laid 159 ± 33.6 eggs over 40.20 ± 8.3 days. The pre-oviposition period was 8.4 ± 1.5 days and the post-oviposition period was 5.1 ± 2.6 days. The eggs were creamy and elliptical, 0.08 ± 0.01 mm in length and 0.03 ± 0.03 mm in width. Larvae were oligopod and elongate with off-white thoracic and abdominal regions and brown head and anal disc. The head-capsule width of the 1st, 2nd and 3rd instars averaged 0.20,0.30 and 0.43 mrn, respectively. Average growth rate for the three larval instars was 1.49. There was a high significant correlation (r = 0.997: P = 0.05).between the mean width of the head-capsules and elapsed developmental period. The pre-pupa was a non-feeding, sluggish larval stage. The means of pre-pupal length and width were 3.6mm and 0.7mm. Pupa was exarate, off-white, and looked like a mummified adult. Pupal length and width averaged 2.9 mm and 1.1 mm, respectively. Sex ratio was 1.5: 1. The head, thorax and elytra of adult were golden brown. Females were significantly larger than males (P= 0.05).

Published: September 2023

Population of Empoasca dolichi Paoli were studied during the rainy seasons of 2000 and 2001 respectively to determine their economic injury levels (EIL) on groundnut in Zaria area, northern Nigeria. Groundnut (Variety RRB) was artificially infested with different population levels of E. dolichi at three different stages of plant growth. The growth stages of the plant at which infestations were made were R1 (groundnut beginning bloom), R4 (Full pod development)and R7 (groundnut beginning maturity). The results showed consistent decreasing groundnut yield with increasing population of E. dolichi. Based on mean groundnut market values and insect control costs for 2000 and 2001, economic-injury levels determined were 1,6 and 13 leafhoppers/plant for groundnut growth stages R1, R4 and R7 respectively.
Ash from Cooking fires Synergizes Efficacy of the Entomopathogenic fungus, Metarhizium anisopliae against Four Major Stored Product Insect Pests
Authors: EKESI S.
Published: September 2023

Combinations of the entomopathogenic fungus Metarhizium anisopliae and ash from cooking fires were tested for the control of Sitophilus zeamais on maize, Sitotroga cerealella on sorghum, Caryedon serratus on groundnut and Callosobruchus maculatus on cowpea. The fungus was tested at rates of 10, 50, 100 and 200 mg conidia/kilogram of grain with and without a single rate of 300 mg of ash/kilogram of grain. Bioassay revealed synergistic effects on all insects at all the dosages of M. anisopliae tested.Combination of the fungus and ash also significantly reduced F1 progeny emergence at levels comparable to high doses of either ash or M. anisopliae alone. The results suggests that the current use of high application rates of conidia for stored grain environment may not be commercially acceptable and the development of effective abrasive formulation of conidia in ash should provide basis for application of conidia at reduced doses which are equally effective as previously used high dose rates.

A survey of plants traditionally used for preserving stored maize (Zea mays– L.) against Sitophilus zeamais Motschulsky was conducted in the late season of 2003 in five villages (Akiegun, Idenro, Ilala, Ileniku and Onigbado) in Abeokuta North Local Government of Ogun State. The plants identified were Aframomum melegueta (Rosch) K. Schum (leaf and seed), Azadirachta indica A. Juss (leaf), Cannabis indica L. (leaf), Capsicum annuum L. (fruit), Cassia sp. (leaf), Khaya grandifoliola C.De. (stem bark), Lophira lanceolata Tiegh. Ex Keay (leaf), Olax subscorpioidea Olivo (leaf). and Secamone afzellii (Schult) K. Schum (leaf). Application of 2.0g stem bark ash and powder of Khaya grandifoliola (Mahogany) per 2Sg maize grain caused significantly (P<0.05)higher weevil mortality, 90.0% and 87.S% respectively, when compared with the control. The mean percentage grains with egg plugs of S. zeamais was significantly lower (P<0.05)being 4.1% and S.9% at 2.0g of bark ash and powder, respectively compared with the control. However, the mean developmental period (egg-adult) of S. zeamais was significantly longer (P<0.05)at the highest dosage (2.0g) of the bark ash and powder of K. grandifoliola. The number of emerged F, adults was significantly lower (P<0.05)at the highest dosage rate 2.0g of bark ash and powder being 12.0 and 18.S adults, respectively, compared with the control, 54.0 and 60.5 adults.
Efficacy of Cow Bone Charcoal Dust in the Management ofthe Maize Weevil, Sitophilus zeamais Motsch. [Coleoptera: Curculionidae], and the Lesser Grain Borer, Rhyzopertha dominica Fab. [Coleoptera: Bostrichidae)), Infesting Stored Maize (Zea mays L.)Grains.

Published: September 2023

Dry bones (femur and ribs) of the African humped cow, Bos indicus (L.), were burnt with wood fire and the resulting charcoal was manually ground and sieved to produce the fine inert cow bone charcoal dust (CBCD) that was admixed-with maize (Zea mays L.) grains at the rates of 0.1 ,0.25,0.5, 1.0,2.0,4.0, and 8.0 g /100 g of grain. Adults of Sitophilus zeamais Motsch. and Rhyzopertha dominica Fab. were exposed to the treated grain and mortality was recorded at 2, 4, 6, and 8 days post-infestation. The study was conducted under ambient conditions (28.5-32.5°C and 50-62 % RH) in the laboratory. For both species, mortality increased significantly (P<0.05) with application rate and exposure interval. CBCD significantly (P<O.01) suppressed F, progeny production and repelled adults from treated grain. Complete inhibition of S. zeamais progeny emergence was achieved with ~ 0.25 g CBCD /100g of grain from the 4th through to the 12th month of storage at ambient laboratory conditions of 23.5- 33°C and 63.5-87.5 % RH. Test with R. dominica gave similar results when 100 g grains were treated with ~ 0.5 g CBCD. The regression of mortality (probit) on rate of application (log) indicated that R. dominica was less susceptible to CBCD than S. zeamais. CBCD appears to have a potential in the management of insect pests of stored grains.

Published: September 2023

Ability of Sitophilus zeamais Motschulsky obtained from four different locations in Nigeria to infest and damage three varieties of maize, Zea mays L., was investigated under ambient laboratory conditions in Akure, Nigeria. Post-infestation adult mortality, FJ progeny emergence, grain perforation, and weight loss in infested maize were assessed. The maize variety TZMl 205, previously reported to be highly resistant to infestation and damage by S. zeamais from Akure, was observed to be similarly resistant to weevil populations from Port Harcourt, Kaduna and Maiduguri. There may be variation among populations of S. zeamais in Nigeria with respect to their ability to damage resistant maize varieties.

A recursive system identification inertia estimator for traditional and converter-interfaced generators
Authors: Gotti Davide , Ledesma Pablo , Amaris Hortensia
Published: September 2023

This paper proposes a method to estimate the inertia constant of synchronous generators (SGs) and the virtual inertia provided by converter-interfaced generators (CIGs). It can be applied when the system is under normal operating conditions or after power imbalance events. The algorithm is based on a recursive system identification approach and uses the active power and bus frequency measurements proceeding from phasor measurement units. The measurements are preprocessed to improve the estimation accuracy. Subsequently, a model-independent rotor speed estimator is used to compute rotor speed variations (or internal frequency variations, in the case of CIGs). Afterwards, a recursive least-square equation error formulation is implemented to compute the SG and CIG parameters in the z-domain, which are later converted into their respective counterparts in the s-domain. The method is applied to several generation devices in the IEEE 39-bus and IEEE 118-bus test systems, including traditional SGs and CIGs providing virtual inertia. Numerical results show the accuracy and the low computational burden of the proposed method.
Efficient analysis of overdispersed data using an accurate computation of the Dirichlet multinomial distribution
Authors: Baddar Sherenaz Al-Haj , Languasco Alessandro , Migliardi Mauro
Published: September 2023

Modeling count data using suitable statistical distributions has been instrumental for analyzing the patterns it conveys. However, failing to address critical aspects, like overdispersion, jeopardizes the effectiveness of such an analysis. In this paper, overdispersed count data is modeled using the Dirichlet Multinomial (DM) distribution by maximizing its likelihood using a fixed-point iteration algorithm. This is achieved by estimating the DM distribution parameters while comparing the recent Languasco-Migliardi (LM), and the Yu-Shaw (YS) procedures, which address the well-known computational difficulties of evaluating its log-likelihood. Experiments were conducted using multiple datasets from different domains spanning polls, images, and IoT network traffic. They all showed the superiority of the LM procedure as it succeeded at estimating the DM parameters at the designated level of accuracy in all experiments, while the YS procedure failed to produce sufficiently accurate results (or any results at all) in several experiments. Moreover, the LM procedure achieved a speedup that ranged from 2-fold to 20-fold over YS.

Emotions in Norwegian language debate
Authors:   Inland Norway University of Applied Sciences, Norway, Haugan Jens
Published: September 2023

Norway has two official Norwegian languages, Bokmål and Nynorsk. The majority of Norwegians use Bokmål as their written language (ca. 80%) which makes Nynorsk a minority language or lesser used language. Ever since the legal decision to have two official written languages (1885) there has been a public debate in Norway which may be fierce and emotional at times. After having investigated emotional expressions regarding the two written languages in the newspaper corpus of the Norwegian National Library we found that emotions are associated with Nynorsk to a much larger extent than with Bokmål. While Nynorsk may be associated with both love and hate, Bokmål can be said to be more default and neutral when it comes to opinions or emotions. /Keywords: language attitudes, language debate, emotions, affective filter
Re-conceptualizing the knowledge base for non-native language teachers to cope with negative emotions
Authors:   Independent Researcher, Kong Xiaojun , Chi Chenkai ,   University of Windsor, Canada
Published: September 2023

When non-native speakers become second language teachers, emotions play a significant role in the teacher-learning process and throughout their professional lives. However, few teacher education programs explicitly relate emotions to teachers’ knowledge bases to improve their social-emotional skills. Due to the dynamic nature of a knowledge base, teachers can always take an inquiry stance to continuously examine their teaching practices and beliefs. Therefore, this paper takes an inquiry stance to discuss negative emotions in non-native language teachers’ narratives and how they can overcome the potentially negative effects of such emotions by reconceptualizing their personal knowledge base to reinforce the effects of positive emotions and minimize the effects of negative emotions in their teaching practice. As a preliminary study, it aims to raise awareness for teachers to develop social-emotional skills through knowledge-base re-conceptualization and to advocate for reform of language teacher education./ Keywords: emotions, social-emotional skills, language teacher education, knowledge base, non-native teachers

Published: September 2023

Os eventos extremos de estiagem ocorridos no Brasil, cada vez mais frequentes, a concentração da população e a elevação do consumo dificultam o abastecimento e geram disputas pelo direito de uso da água. Essa situação se agrava ainda mais devido ao índice de perdas de água médio no Brasil atingir patamares de 40% na última década. O objetivo principal foi propor o gerenciamento dos itens importantes ao controle de perdas a partir de seus subitens, pela aplicação de indicadores. Os indicadores ponderaram a qualidade e a influência de técnicas, materiais e procedimentos sobre as perdas. O método foi aplicado ao município de Monte Alto - SP, o qual apresentou sensível redução de perdas. Foram escolhidos nove indicadores de gerenciamento de itens (IGitem) do sistema de abastecimento de água, que foram analisados no período de 1996 a 2005. Esses itens foram desdobrados em quarenta e três subitens, aos quais se atribuíram pesos por especialistas e, periodicamente, pontuações (0 a 100) (IGsubitem), que geraram nove IGitem. A média ponderada dos nove IGitem representou o índice geral de gerenciamento de perdas de água (IGGPA). Os levantamentos de dados e as interações com funcionários resultaram em relatórios, a base das pontuações. A pontuação de cada subitem, por ser mais simples e verificável, resultou mais verossímil a valoração do item e, por conseguinte, do IGGPA. Foram identificadas quarenta e três ações gerenciais positivas para o SAA e dezesseis ações negativas no período. Notou-se defasagem nas respostas entre o IGGPA e índices convencionais por questões intrínsecas aos índices, mas percebeu-se coerência entre eles.

Using experimental studies of mobile exploration technology, which includes modified methods of frequency-resonance processing, decoding of satellite and photographic images, vertical electron resonant scanning of the geological section, and the method of integral assessment of oil and gas content, the authors identified the potential of large prospecting blocks and licensed areas within the Shakal and Halabja blocks in Kurdistan. In the Shakal exploration area, the authors received oil responses from 3 intervals: 1) 2771-2794 m, 2) 2795.3-2815.45 m, and 3) 2834.40-2854 m in limestone sections. In Halabja exploration area, oil responses were obtained from 12 intervals: 1) 297-311.5 m, 2) 328-330 m, 3) 1190-1260 m, 4) 2018-2020 m, 5) 2059-2061 m, 6) 2132-2133 m, 7) 2192-2201 m, 8) 2249-2276 m, 9) 2307-2310 m, 10) 2317-2321 m, 11) 2326-2329 m and 12) 3310-3340 m. These results suggest that the proposed alternative exploration model can provide a more direct means of assessing the hydrocarbon potential of large exploratory areas, even before other geophysical investigations provide detailed information on possible targets.

Coraz częściej podejmując działania dotyczące przedsiębiorstwa, należy mieć na uwadze relacje pomiędzy dostawcą a odbiorcą, które są niezbędnym elementem decydującym o jego obecności na rynku. W tym obszarze coraz częściej doceniany jest również kapitał ludzki, wiedza oraz kapitał intelektualny, zwłaszcza w długim okresie. Coraz więcej przedsiębiorstw rozumie, że zarządzanie wiedzą, to krok w kierunku doskonalenia nie tylko wybranego procesu (w badanym przypadku w obszarze współpracy z dostawcami) ale również całej organizacji. Celem niniejszego artykułu jest sprawdzenie, czy w przedsiębiorstwach działających w Polsce w branży metalowej, załoga podświadomie wykorzystuje elementy zarządzania wiedzą - wdrażanie wypracowanych w przedsiębiorstwie praktyk, modyfikacja istniejących procedur postępowania, dzielenie się wiedzą w zespole, samodzielne działania usprawniające wykonywanie pracy- o których być może nigdy nie słyszała. Instrumentem badawczym, który pozwolił na uzyskanie wyników była ankieta. Najważniejszym elementem przeglądu otrzymanych wyników była analiza ważności czynników zarządzania wiedzą oraz ich wpływu na kształtowanie się wzajemnych relacji pomiędzy dostawcami i partnerami wybranych przedsiębiorstw branży metalowej w kontekście wybranych zasad zarządzania Toyoty. Przyjęte podejście umożliwiło zidentyfikowanie różnic w odpowiedziach ankietowanych w obu grupach przedsiębiorstw, dając jednocześnie podstawy do dalszych badań nad kierunkami doskonalenia współpracy z dostawcami wykorzystując elementy zarządzania wiedzą.

W obecnych czasach problemy związane ze zrównoważonym transportem oraz ograniczeniem negatywnego oddziaływania na transportu stanowią istotny element agendy Unii Europejskiej jak i wielu krajów w Europie i na świecie. Jednocześnie na zwiększenie popularności pojazdów bezemisyjnych i niskoemisyjnych może mieć wpływ globalna sytuacja na rynku paliw kopalnych i rosnące ceny ropy naftowej. Ze względu na swoje cechy charakterystyczne, wykorzystanie pojazdów bezemisyjnych i niskoemisyjnych jest zasadne zwłaszcza a miastach, zarówno w transporcie indywidualnym jak również w komunikacji miejskiej i w transporcie towarowym. W artykule skupiono się na analizie perspektyw dla wykorzystania pojazdów bezemisyjnych i niskoemisyjnych w systemach dystrybucyjnych (zwłaszcza w miastach). W związku z tym celem badawczym artykułu jest odpowiedź na pytanie: jakie są przewidywane trendy w zakresie poziomu wykorzystania pojazdów bezesmisyjnych i niskoemisyjnych w systemach dystrybucyjnych? Hipoteza badawcza zakłada, że poziom wykorzystania pojazdów bezemisyjnych i niskoemisyjnych w systemach dystrybucyjnych będzie rósł w najbliższych latach biorąc pod uwagę sytuację na globalnym rynku paliw. Do weryfikacji hipotezy wykorzystano takie metody badawcze jak desk research (w tym analiza danych z rynku paliw) oraz krytyczny przegląd literatury. W ramach przeprowadzonych badań wykorzystano rzeczywiste dane dotyczące funkcjonowania miejskich systemów dystrybucyjnych oraz dane techniczne poszczególnych pojazdów. W artykule zbadano możliwość wykorzystania pojazdów dostawczych o różnej ładowności, które mogą być wykorzystywane w systemach transportowych o zróżnicowanej specyfice. Z przeprowadzonych badań wynika, że biorąc pod uwagę aktualne trendy na rynku paliw, w perspektywie najbliższych 5-10 lat koszty eksploatacji pojazdów bezemisyjnych oraz niskoemisyjnych staną się niższe od kosztów eksploatacji pojazdów konwencjonalnych, co będzie prowadziło do zwiększenia poziomu ich wykorzystania w miejskich systemach dystrybucyjnych. Ponadto, warto zauważyć że wyżej opisany trend jest zgodny ze strategiami rozwoju transportu definiowanymi na poziomie Unii Europejskiej oraz poszczególnych krajów. Uzyskane rezultaty badań mogą stanowić bazę dla dalszych praz nad opłacalnością i zasadnością wykorzystania pojazdów bezemisjynych oraz niskoemisyjnych w systemach logistyki miejskiej.

W artykule przedstawiono administracyjno-prawne regulacje organizacji zgromadzeń publicznych
w odniesieniu do kompetencji państwa w zakresie logistyki bezpieczeństwa. Celem artykułu jest wskazanie
prawnych możliwości państwa w zakresie organizacji zgromadzeń publicznych. Problem badawczy został
sformułowany w postaci pytania: W jaki sposób organy władzy publicznej, realizujące zadania z zakresu
logistyki bezpieczeństwa państwa, swoim działaniem wypełniają konstytucyjną normę przyznającą osobie
wolność zgromadzeń? Hipoteza badawcza poddana weryfikacji to: Władza publiczna ma szerokie możliwości
zarówno w zakresie organizacji zgromadzeń publicznych, jak i zapewnienia ich bezpieczeństwa. Nie bez
znaczenia dla logistyki bezpieczeństwa zgromadzenia publicznego jest okres między jego zgłoszeniem a
odbyciem. Rozważania tematu zostaną oparte na dostępnej literaturze przedmiotu, aktach normatywnych,
osobistych obserwacjach, a także innych źródłach informacji obrazujących przebieg i kontrolę zgromadzeń
publicznych. Kluczowe znaczenie dla rozpatrzenia tematu będzie miała również ocena władz samorządowych dokonujących oceny zarejestrowanych manifestacji, a także ich wniosków o zezwolenie na odbycie
zgromadzenia lub jego zakaz. Wnioski z przeprowadzonych badań zostały sformułowane w ostatniej
części artykułu. Jako najistotniejsze wnioski wskazać należy, że, władza publiczna posiada szeroki zakres
kompetencji zarówno w zakresie organizacji, jak i możliwości zapewnienia bezpieczeństwa publicznego.
Ponadto, wprowadzona w 2015 roku znowelizowana ustawa o zgromadzeniach publicznych znacząco
przyczyniła się do zwiększenia uprawnień samorządów.
Electrolytic Process for Concentrating Trace Tritium in Water for Tritium Activity Measurement by Liquid Scintillation Counter
Authors: Mamun Al
Published: September 2023

In arid regions, the water contains very low levels of tritium, which cannot be detected by conventional liquid scintillation counters (LSC). For the evaluation of the tritium activity concentration, it is crucial to enrich the low-level tritium of groundwater with a known factor. To address this, we developed an electrolysis process with specially designed electrolytic cells following the guidelines of the International Atomic Energy Association (IAEA). The electrolysis process enriched nine spiked samples with known quantities of tritium, and the tritium activity concentration was measured by a scintillation counter. The enriched water showed comparable activity levels to the spiked samples. In addition, the enrichment factor and tritium activity are correlated. Our study demonstrated that the electrolysis process with fabricated electrolytic cells could achieve an enrichment factor of approximately ten to forty times the initial tritium concentration. The simple design and fabrication of the electrolysis process and its ability to control various parameters make it cost-effective for measuring low-level tritium using a conventional LSC.
Vaccine Hesitancy Among Us Travelers

Diseases are increasing in prevalence around the world. American travelers are at greater risk of contracting the disease when traveling outside the country to an endemic region. The safety of visitors to mosquito-endemic destinations is more important than ever. Because a vaccine does
not exist for prevention or as a prophylactic, tourists are in jeopardy of fatal sicknesses. Thus, if a vaccine existed, it would be important to understand the likelihood of taking such a vaccine. This study sought to identify specific demographic and attitudinal variables that may be the
best predictors of the likelihood of getting a Chikungunya virus (CHIKV) vaccine. An online survey of US travelers intending to travel to the Caribbean in the next 3‐5 years was used to gather information related to personal protection motivations, behaviors, and knowledge of CHIKV. Hierarchical
logistic regression was used to determine the best predictor of getting a CHIKV vaccine. Results suggested that the best predictor of getting the vaccine was trust. Using scenarios and predicting the use of vaccines in today’s environment are effective ways of determining vaccine support
and the likelihood of engaging in this personal protective behavior, should it become commercially available. Such efforts can improve ways to manage, control, and message regarding CHIKV.
Determining Whether Gender of External Instructional Supervisors Influence Public Secondary School Teachers’ Performance in Ndhiwa Sub-county, Homabay County
Authors: Lavina Achar Judith , Ogochi George
Published: September 2023

In the recent past, external instructional supervision of teachers has been known to have an impact on the student’s performance and more especially on the KCSE performance. The purpose of this study is to investigate the influence of external instructional supervision on public secondary school teachers’ performance in the Ndhiwa sub-county. The researcher believes that the process of supervision is a collaboration among the stakeholders in Education. The researcher used simple random sampling to select 15 public secondary schools, 15 secondary school principals and 103 teachers; purposive sampling was used to automatically select instructional supervisors (one QASO and one TSC sub-county director) from the Ndhiwa sub-county. Questionnaires were used as a data collection instrument for teachers, principals, and supervisors (QASO) and an interview guide for the TSC sub-county director. The data collected was subjected to the statistical package for social sciences to generate descriptive statistics. Thematic analysis was also carried out on the qualitative data. The study established that teachers’ performance is improved if the supervisor is usually warm and friendly to teachers, always assists the teacher where they go wrong, and often tries to be fair, firm, open and transparent in their dealings with teachers. The study established that supervisors always possess the necessary problem-solving skills, skills to observe teachers, skills for designing instruments for evaluation and whether supervisors help schools promote peace among staff and students. The study established that supervisors visiting school could easily improve cooperation with teachers by giving guidance and advice; teachers regarded them as professional colleagues and not as subordinates or inferiors
