Published: October 2020

Purpose: The purpose of this was to analyze the influence of knowledge creation on organizational performance of state owned commercial enterprises in Kenya. Methodology: This study was based on explanatory and descriptive research designs since they were more appropriate to test the hypotheses. The target population comprised of 275 members of top management team of 55 state-owned commercial enterprises in Kenya, as at 31st October 2016. The study utilized simple random sampling to select a sample of 268 members of top management team in the 55 state-owned commercial enterprises.Results: Response rate of 71% was obtained and analytical tests conducted were Pearson correlation coefficients, One Way ANOVA, and Multiple linear regression. The correlation coefficients for return on equity was (r = -0.035, p=0.635) and return on asset was (r = 0.063, p = 0.388). One-Way ANOVA results was F (14, 173) = 2.483, p=0.003. The regression for coefficient based on return on equity for knowledge creation was: unmoderated models; β = -1.044, t (-1.657), p=0.1 and for moderated model; β = -7.317, t (-4.505), p=0.000 respectively. The regression coefficient based on return on asset model for knowledge creation was: unmoderated models; β=0.134 t (0.608) p = 0.544 and for moderated models; β = -0.335, t (-0.533), p = 0.595. The study concludes that there is no significant influence of knowledge creation on performance based on return on assets but there is significant influence of knowledge creation on organizational performance based on return on equity of state owned commercial enterprises in Kenya.Contribution to Practice, Theory and Policy: Based on the findings that knowledge creation influences the organizational performance of state owned commercial enterprises in Kenya, the study recommends that organizations should encourage the collaboration, practice, education, and interaction as ways of creating knowledge.

Authors: Chepkemboi Eunice Thecla , Paul Dr. Samson Nyang’au
Published: October 2020

Purpose: This study sought to identify the effect of the uptake of disruptive innovations on the performance of selected airlines in Kenya. Its specific objectives included to determine the impact of digital platforms, mobile technology, Blockchain technology and travel intermediaries on the performance of selected airline in Kenya. This study was restricted to three airlines in Kenya, namely, Kenya Airways, Jambojet and Fly540.Methodology: It focused on 120 staff working within the Nairobi offices of these airlines based on their familiarity with strategic initiatives employed in responding to disruptive innovations. The theoretical review featured the following theories: the theory of disruptive innovations; radical innovations theory; the theory of open innovation; and diffusion of innovations theory. This study applied a descriptive research design since it was focussed on describing the characteristics of the participants involved in the study since this is a social research. It adopted a census method for determining the sample size. It used self-administered questionnaires on 120 respondents from the target population who were given two weeks to complete the questionnaires before collection using a drop and pick arrangement was adopted. The study used a five point Likert scale to develop the questionnaire to use in tandem with two measures of central tendency, standard deviation and mean, to describe the data. The data was then examined using the Statistical Package for Social Sciences (version 22) to conduct regression analysis, descriptive analysis and inferential analysis. The results were then presented using graphs and tables.Results: The results indicate that travel intermediaries had the strongest positive correlation with performance followed by mobile technology adoption, digital platforms and blockchain technology, respectively. Further, whilst organisations in the industry have established commendable strategies to ensure digital platforms reliability and mobile technology adoption, they have yet to embrace blockchain technology as a strategy for coping with disruptive innovations. The same case applies to travel intermediaries where the local airline companies have not implemented effectively thus losing market to other upcoming international airlines.Unique contribution to theory, practice and policy: The study recommends that the management of airlines in Kenya to adopt blockchain technology in order to further strengthen their IT systems and use this as a means of resisting possible blockchain technology-driven disruptive innovations. The companies also ought to embrace appropriate technologies to support travel intermediaries through which they tap the low income earners thus sustaining their performance.

Published: October 2020

Purpose: The focus of this study was on assessment of competitive strategies adopted by players in the beer industry in KenyaMethodology: The study adopted a cross sectional descriptive survey research design. There are 11 players in beer industry operating in Kenya. The research therefore took the form of a census study covering all the players in the beer industry in Kenya since the population of 11 firms was considered small enough. Eleven questionnaires were given out though only 10 were considered fit for data analysis. Data was analyzed using descriptive statistics.Results: Findings indicated that players in beer industry in Kenya were faced by several forces that shape competition. These included competitive rivalry, threat of new entrants, bargaining power of suppliers and customers, globalization, regulation and information technology. Players in beer industry in Kenya used cost leadership strategy as a competitive strategy since they attempt to reduce their operational costs in order to deliver the product at the lowest prices. It was also possible to conclude that players in beer industry in Kenya use differentiation as a competitive strategy since they have invested in product research. Players in beer industry in Kenya also used focus as a competitive strategy since they have products for different types of consumers. It was also possible to infer from this study that players in beer industry in Kenya used value disciplines as a competitive strategy.Unique contribution to theory, practice and policy: The study recommended that players in beer industry should carry out constant environment scanning so as to be able to identify the various forces that affect their operations. In addition, they needed to adopt strategic planning as a tool for planning against any unforeseen events that may destabilize the operations of the company.  Finally, it was recommended that these players needed to continue using the various competitive strategies. However, they also needed to factor in the concept of strategy fit by considering the internal capabilities and resources of the firm.

STUDENT SATISFACTION AND TECHNOLOGY INTEGRATION IN TEACHING AND LEARNING: THE CASE OF UNIVERSITY EDUCATION IN NAMIBIA
Authors: Semente Efigenia
Published: October 2020

Purpose of the study: The purpose of this study is to assess Student Satisfaction and Technology Integration in Teaching and Learning:  The Case of University Education in Namibia. The concept of customer satisfaction has attracted much attention in recent years. Institutions of higher education are accountable for their performance to their trustees, state boards, accreditation agencies, employees, parents, and of course, their students. Students are the reason for the existence of Institutions of higher education. Hence Student satisfaction should be the core business of such institutions. Yet despite a large body of research literature examining customer satisfaction and student satisfaction for that matter, researchers have not fully investigated the relationship between student satisfaction and technology integration in teaching and learning.  This study explores the Challenges faced by academics in terms of technology integration in teaching and learning.  It further assesses Students’ Satisfaction in relation to Technology Integration in Teaching and Learning as well as the relationship between the use of technology in teaching and learning and Students Satisfaction. Research Methodology: This is a correlation cross-sectional quantitative survey. Responses were obtained from a 200 valid random sample comprising of Students and Lecturers at one of the major public Universities in Namibia.  The responses were analysed using SPSS version 23.  Both descriptive and inferential statistics were used to examine the research questions.  Descriptive statistics were used to report demographic information and for inferential statistics, the principal components analysis (PCA) was used.  Further, in order to explore the relationships between Student Satisfaction and Technology Integration in Teaching and Learning, Pearson correlation and analysis of variance (ANOVA), were used to address research questions accordingly.Findings: The study found significant relationships between Technology Integration in Teaching and Learning and Students Satisfaction. The results prompted recommendations guiding effective marketing strategies for Institutions of Higher Education,   policy making in relation to Technology Integration in Teaching and Learning vis-à-vis Student Satisfaction.Contribution: Regular appraisal of students satisfaction with technology integration is critical. Evaluation of lecturer’s perception and awareness of technology integration is essential-to reduce the Knowledge Gap in the area of technology integration in teaching and learning. Specific studies related to technology integration in teaching and learning per discipline (Programme) are desirable since different Programmes may have different needs in terms of technology integration. Lecturers’ commendations/support for technology integration is key to ensure adoption and full technology integration in the long run. Institutional Policy on course web/e-learning presence is fundamental

Abstract. To understand the Korean Peninsula's carbon dioxide (CO2) emissions and sinks as well as those of the surrounding region, we used 70 flask-air samples collected during May 2014 to August 2016 at Anmyeondo (AMY; 36.53∘ N, 126.32∘ E; 46 m a.s.l.) World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) station, located on the west coast of South Korea, for analysis of observed 14C in atmospheric CO2 as a tracer of fossil fuel CO2 contribution (Cff). Observed 14C ∕ C ratios in CO2 (reported as Δ values) at AMY varied from −59.5 ‰ to 23.1 ‰, with a measurement uncertainty of ±1.8 ‰. The derived mean value Cff of (9.7±7.8) µmol mol−1 (1σ) is greater than that found in earlier observations from Tae-Ahn Peninsula (TAP; 36.73∘ N, 126.13∘ E; 20 m a.s.l., 28 km away from AMY) of (4.4±5.7) µmol mol−1 from 2004 to 2010. The enhancement above background mole fractions of sulfur hexafluoride (Δx(SF6)) and carbon monoxide (Δx(CO)) correlate strongly with Cff (r>0.7) and appear to be good proxies for fossil fuel CO2 at regional and continental scales. Samples originating from the Asian continent had greater Δx(CO) : Cff(RCO) values, (29±8) to (36±2) nmol µmol−1, than in Korean Peninsula local air ((8±2) nmol µmol−1). Air masses originating in China showed (1.6±0.4) to (2.0±0.1) times greater RCO than a bottom-up inventory, suggesting that China's CO emissions are underestimated in the inventory, while observed RSF6 values are 2–3 times greater than inventories for both China and South Korea. However, RCO values derived from both inventories and observations have decreased relative to previous studies, indicating that combustion efficiency is increasing in both China and South Korea.

Abstract. Ensemble simulation of the general atmospheric circulation of the middle and upper atmosphere up to the lower thermosphere is performed using the 3-D nonlinear mechanistic numerical model MUAM. Residual mean meridional circulation (RMC) in terms of the Transformed Eulerian Mean is calculated for the boreal winter and changes in its vertical and meridional velocity components during different phases of simulated composite stratospheric warming (SW) events are studied. The simulation results show general decrease in RMC velocity components up to 30 % during and after SW in the mesosphere and lower thermosphere of the Northern Hemisphere. There are also increases in the downward and northward velocities at altitudes 50–70 km at the northern high latitudes. Associated changes in adiabatic heating/cooling rates can contribute to heating the stratosphere and cooling the mesosphere during the composite SW. The changes in the transport of conservative species (like ozone) during SWs are estimated. Weakening of ozone fluxes at the middle latitudes of the Northern Hemisphere may reach 30 % during SWs and 30–40 % after the events at the altitudes of stratospheric maximum of ozone concentration. Such statistically confident simulations of RMC reactions on SWs at altitudes up to the lower thermosphere are performed for the first time. The study of the residual meridional circulation is useful for effective analysis of wave impacts on the mean flow and for diagnostics of the transport of atmospheric gas species in the atmosphere.

Abstract. The patterned microtopography of subarctic mires generates a variety of environmental conditions, and carbon dioxide (CO2) and methane (CH4) dynamics vary spatially among different plant community types. We studied the CO2 and CH4 exchange between a subarctic fen and the atmosphere at Kaamanen in northern Finland based on flux chamber and eddy covariance measurements in 2017–2018. We observed strong spatial variation in carbon dynamics between the four main plant community types (PCTs) studied, which were largely controlled by water table level and differences in vegetation composition. The ecosystem respiration (ER) and gross primary productivity (GPP) increased gradually from the wettest PCT to the drier ones, and both ER and GPP were larger for all PCTs during the warmer and drier growing season 2018. We estimated that in 2017 the growing season CO2 balances of the PCTs ranged from −20 g C m−2 (Trichophorum tussock PCT) to 64 g C m−2 (string margin PCT), while in 2018 all PCTs were small CO2 sources (10–22 g C m−2). We observed small growing season CH4 emission sums (

Abstract. Accurate estimates of past global mean surface temperature (GMST) help to contextualise future climate change and are required to estimate the sensitivity of the climate system to CO2 forcing through Earth's history. Previous GMST estimates for the latest Paleocene and early Eocene (∼57 to 48 million years ago) span a wide range (∼9 to 23 °C higher than pre-industrial) and prevent an accurate assessment of climate sensitivity during this extreme greenhouse climate interval. Using the most recent data compilations, we employ a multi-method experimental framework to calculate GMST during the three DeepMIP target intervals: (1) the latest Paleocene (∼57 Ma), (2) the Paleocene–Eocene Thermal Maximum (PETM; 56 Ma), and (3) the early Eocene Climatic Optimum (EECO; 53.3 to 49.1 Ma). Using six different methodologies, we find that the average GMST estimate (66 % confidence) during the latest Paleocene, PETM, and EECO was 26.3 °C (22.3 to 28.3 °C), 31.6 °C (27.2 to 34.5 °C), and 27.0 °C (23.2 to 29.7 °C), respectively. GMST estimates from the EECO are ∼10 to 16 °C warmer than pre-industrial, higher than the estimate given by the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (9 to 14 °C higher than pre-industrial). Leveraging the large “signal” associated with these extreme warm climates, we combine estimates of GMST and CO2 from the latest Paleocene, PETM, and EECO to calculate gross estimates of the average climate sensitivity between the early Paleogene and today. We demonstrate that “bulk” equilibrium climate sensitivity (ECS; 66 % confidence) during the latest Paleocene, PETM, and EECO is 4.5 °C (2.4 to 6.8 °C), 3.6 °C (2.3 to 4.7 °C), and 3.1 °C (1.8 to 4.4 °C) per doubling of CO2. These values are generally similar to those assessed by the IPCC (1.5 to 4.5 °C per doubling CO2) but appear incompatible with low ECS values (<1.5 per doubling CO2).
Topographic controls on divide migration, stream capture, and diversification in riverine life
Authors: Lyons Nathan J. , Val Pedro , Albert James S. , Willenbring Jane K. , Gasparini Nicole M.
Published: October 2020

Abstract. Drainages reorganise in landscapes under diverse conditions and process dynamics that impact biotic distributions and evolution. We first investigated the relative control that Earth surface process parameters have on divide migration and stream capture in scenarios of base-level fall and heterogeneous uplift. A model built with the Landlab toolkit was run 51 200 times in sensitivity analyses that used globally observed values. Large-scale drainage reorganisation occurred only in the model runs within a limited combination of parameters and conditions. Uplift rate, rock erodibility, and the magnitude of perturbation (base-level fall or fault displacement) had the greatest influence on drainage reorganisation. The relative magnitudes of perturbation and topographic relief limited landscape susceptibility to reorganisation. Stream captures occurred more often when the channel head distance to divide was low. Stream topology set by initial conditions strongly affected capture occurrence when the imposed uplift was spatially heterogeneous. We also integrated simulations of geomorphic and biologic processes to
investigate relationships among topographic relief, drainage reorganisation, and riverine species diversification in the two scenarios described above. We used a new Landlab component called SpeciesEvolver that models species at landscape scale following macroevolutionary process rules. More frequent stream capture and less frequent stream network disappearance due to divide migration increased speciation and decreased extinction, respectively, especially in the heterogeneous uplift scenario in which final species diversity was often greater than the base-level fall scenario. Under both scenarios, the landscape conditions that led to drainage reorganisation also controlled diversification. Across the model trials, the climatic or tectonic perturbation was more likely in low-relief landscapes to drive more extensive drainage reorganisation that in turn increased the diversity of riverine species lineages, especially for the species that evolved more rapidly. This model result supports recent research on natural systems that implicates drainage reorganisation as a mechanism of riverine species diversification in lowland basins. Future research applications of SpeciesEvolver software can incorporate complex climatic and tectonic forcings as they relate to macroevolution and surface processes, as well as region- and taxon-specific organisms based in rivers and those on continents at large.

Published: October 2020

In this paper we present a new extension of tripled fixed point theorems in metric spaces endowed with a reflexive binary relation that is not necessarily neither transitive nor antisymmetric. The key feature in this tripled fixed point theorems is that the contractivity condition on the nonlinear map is only assumed to hold on elements that are comparable in the binary relation. Next on the basis of the tripled fixed point theorems, we prove the existence and uniqueness of positive definite solutions of a nonlinear matrix equation of type

Modelos económicos: su influencia en la geografía del desarrollo hondureño
Authors: Meza Palma Oscar Oswaldo
Published: October 2020

Este artículo incursiona en el problema de polarización socioeconómica de la sociedad hondureña, cuya fuerza productiva y modernidad se han concentrado en apenas un par de polos urbanísticos e industriales de desarrollo2, a expensas del resto mayoritario de regiones internas, donde se padecen altos grados de desigualdad y postergación. Se propone una explicación de sus causas y consecuencias, desde una perspectiva histórica que revisa un período a partir de 1899 hasta la fecha, reflexionando sobre las implicaciones que tuvieron las decisiones de política y los modelos de desarrollo económico adoptados por la clase gobernante en el devenir del tiempo para encausar un desarrollo equitativo. El estudio revela la influencia que esta combinación de aspectos inherentes a la toma de decisiones de más alto nivel jugó un rol determinante para moldear nuestro actual mapa de asimetrías entre regiones internas de país; que hoy día debilita esfuerzos hacia un despegue económico inclusivo de nuestra sociedad. Se sustenta una información de valiosa importancia en la planificación del desarrollo frente a los ingentes desafíos de la globalización en la que estamos inmersos.

Materials and Methods: In this observational diagnostic accuracy study, a consecutive convenience sample of all adult patients (older
than 16 years) with multiple trauma (injuries confined to at least two body regions) admitted to the trauma bay of the ED during the
shifts of the researchers was used. Presence of ED mortality was recorded, and RTS, EMTRAS, and GAP scores were calculated at the
analysis stage of this study.
Results: The study sample included 279 multiple trauma patients. Of the 279 patients, 13 (4.7%) died in the ED. Among the 266
patients who survived to hospital admission, 3 were lost to-follow-up (foreigner patients). In the following 30 days, 28 more patients
were lost, 23 in the Intensive Care Unit (ICU) (23/62, 37.1%), 4 in the wards (4/131, 3.1%), and 1 after discharge (1/73, 0.1%). The
prognostic accuracies (AUC) of RTS, EMTRAS, and GAP were 0.92, 0.94, and 0.93, respectively, for ED mortality.
Conclusion: In this study, all trauma scores performed similar in the ED for the prediction of ED mortality.

Authors: İŞÇİTÜRK Gökçe BECİT
Published: October 2020

This study aims to determine the nomophobia levels of pre-service teachers, the variables affecting their nomophobia levels, and the relationship between the levels of nomophobia and cyberloafing. The study, which was designed as a correlational study, was conducted with the voluntary participation of 666 pre-service teachers. The data of the study were collected using a personal information form, the Nomophobia Scale (NMP-Q), and the Cyberloafing Scale. The results showed that 528 students (79.3%) had a moderate and high level of nomophobia while 138 students (20.7%) had a low level of nomophobia. As a result of the analyses conducted to determine whether the nomophobia levels of teacher trainees differed depending on gender, it was seen that the nomophobia level of women was statistically higher than that of men. It was concluded that the nomophobia levels of the pre-service teachers did not vary depending on the level of education and their experience of using smartphones. Although, the results gathered from the first analysis results indicated that the nomophobia levels of the pre-service teachers depicted difference concerning the departments at which they studied, this difference proved insignificant as indicated by the anteceding detailed analyses carried out. It was concluded that the nomophobia levels of the pre-service teachers differed significantly depending upon the amount of time they spend on social media. The last finding of the study concluded that cyberloafing significantly predicted nomophobia levels of pre-service teachers. Based on this result, it can be said that the pre-service teachers’ cyberloafing behaviors will increase their tendency to exhibit nomophobic behaviors. For further research, mixed studies in which qualitative methods will also be used to obtain more in-depth data can be designed. It was also found out that the nomophobia levels of the pre-service teachers differed significantly based on their daily social media usage time.
Teachers’ Concern and Professional Development Needs in Adopting Inclusive Education in Saudi Arabia, Based on Their Gender for Vision 2030
Authors: Asiri Abdullah Ali
Published: October 2020

This study looks into the concerns and the required professional development for adopting an inclusive education system, as expressed by elementary school teachers, based on their gender in Saudi Arabia. Participants in this research were special and general education teachers randomly selected from elementary schools in Riyadh, Saudi Arabia, which have special education programs. The theoretical framework of the study was the Concern Based Adoption Model (CBAM). Non-experimental cross-sectional survey was used to collect data. Data were obtained from 332 teachers, i.e., the response rate was 83%. The Stages of Concerns Questionnaire (SoCQ) provided by CBAM indicated that respondent stages of concern 0–2 (Unconcerned, Informational, and Personal) ranked the highest, while stages 4–6 (Consequence, Collaboration, and Refocusing) ranked the lowest. This profile was identified as a “non-user profile”, meaning respondents wanted more information about inclusive education. Teachers, in general, showed interest for professional development on inclusive education, including immediate training and seminars/workshops. The only significant difference in interest for professional development was by gender. The t-test indicated that female teachers have more interest for professional development compared to male teachers.

Asistencia sexual y diversidad funcional. Representaciones a través del discurso de profesionales de la sexología
Authors: Alonso Sánchez José Francisco , Muyor Rodríguez Jesús
Published: October 2020

En este trabajo exploramos los puntos de vista, las opiniones y las representaciones sociales que realizan profesionales de la sexología sobre la Asistencia Sexual. A través de una metodología cualitativa, utilizamos como técnicas de investigación los grupos de discusión y la entrevista semiestructurada a informantes clave. Entre los principales hallazgos encontramos que los profesionales estudiados tienen una visión liberal de la sexualidad de las personas con discapacidad, pero la desarrollan desde una perspectiva individual, asistencialista y terapéutica. Los profesionales configuran la Asistencia Sexual como una forma de terapia sexológica que favorece la rehabilitación de las personas con discapacidad. Se trata de un modelo alineado con una perspectiva patológica de la sexualidad en las personas con diversidad funcional y que, a su vez, encuentra en ese argumento una justificación para diferenciar la Asistencia Sexual de la prostitución o del estigma del trabajo únicamente sexual.

CHARAKTER WSPÓŁCZESNYCH ZAGROŻEŃ IMPREZ MASOWYCH
Authors: Socha Izabella
Published: October 2020

W Polsce kwestie bezpieczeństwa imprez masowych reguluje w sposób kompleksowy ustawa
z 20 marca 2009 r. o bezpieczeństwie imprez masowych. Ustawa określa m.in. zasady
postępowania konieczne do zapewnienia bezpieczeństwa imprez masowych oraz ich warunki
bezpieczeństwa. Imprezy masowe są szczególnie narażone na wystąpienie zagrożenia
bezpieczeństwa z uwagi, iż uczestniczy w nich duża liczba osób. Do najczęstszych zagrożeń
związanych z masowymi imprezami sportowymi należy zaliczyć: „zadymy” i bójki wywoływane
przez pseudokibiców, zamachy terrorystyczne, katastrofy budowlane, awarie techniczne
czy katastrofy naturalne. Każde z wymienionych zagrożeń wywołują wśród ludzi
stres i zjawisko paniki.
