Students’ Perceptions of the Pedagogical Content Knowledge of Chemistry Teachers on the Concept of Hybridization

Students’ perceptions of their teachers have been reported in literature to influence their interest, attitudes and motivation to learn and also influence their understanding of concepts in a subject. To improve the understanding of concepts in topics taught in our schools, there is the need for students to have a positive perception of their teachers and their pedagogical content knowledge, PCK. Thus, the study investigated Senior High School students’ perception of their chemistry teachers’ pedagogical content knowledge in hybridization. A mixed method was adopted using the sequential exploratory mixed approach design. Purposive sampling was used to sample six (6) Senior High Schools for the study. Simple random sampling was used to sample hundred and twenty (120) students to respond to students’ questionnaire for the study, out of which convenient sampling was also used to select 24 students for the interview. A self-constructed questionnaire and a semi-structured interview were the main data collection instruments. The data was analyzed by employing descriptive statistics and content analysis. The findings revealed that, the overall mean of student’s perception of their teachers’ PCK in teaching concepts of hybridization was negative (M = 2.702, SD = 0.898). The results also reveal that, the students’ perception on assessment methods (M=3.01, SD = 0.816) was rated above the criterion mean of 3.0, implying the PCK of the teacher was positive. However, the student’s perception on teacher illustrations and demonstrations (M=2.70, <I>SD </I>= 0.947)), teaching methodology (M=2.91, SD =0.906), teaching and learning materials (M = 2.62, <I>SD </I>= 0.910) and students learning interest (M=2.27, SD =0.912) were negative below the criterion mean of 3.0. Because of this, teachers should use student-centered methodologies, teaching and learning materials, illustrations and demonstrations, and an understanding of their students while teaching abstract concepts like hybridization to ensure that their students learn in a meaningful way.

Performance Study of Generalized Space Time Block Coded Enhanced Fully Optical Generalized Spatial Modulation System Based on Málaga Distribution Model

This paper proposes a generalized space time block coded (GSTBC) enhanced fully optical generalized spatial modulation (EFOGSM) system based on Málaga (M) turbulent channel. GSTBC-EFOGSM adopts the hybrid concept of generalized space time block coded and optical spatial modulation to further utilize the high transmission rate of EFOGSM and the diversity advantage of GSTBC in free space optical (FSO) communication systems. Considering the combined effects of path loss, pointing error and atmospheric turbulence, the Meijer G function is used to derive the closed-form expression for the average bit error rate (ABER) of GSTBC-EFOGSM. Then, the ABER performance, data transmission rate, energy efficiency and computational complexity at the receiver of GSTBC-EFOGSM are compared with other optical spatial modulation schemes by simulation. In addition, the effects of key factors, such as data transmission rate, encoding ratio, number of photodetectors and modulation order, on the ABER performance of the system are also analyzed via simulation. Monte Carlo (MC) simulation is used to verify the correctness of the numerical simulation. The simulation results show that the GSTBC-EFOGSM system has better ABER performance and good performance gain.

The Ottomans Conquer Latin America: The Rise of Turkish Melodramas

This article explores the Turkish telenovela phenomenon that has swept Latin America since 2014 and, more recently, the Hispanic media market in the US. Drawing on media scholar Marwan Kraidy's concept of hybridity, the article examines the processes and conditions that created fertile ground for the enthusiastic reception of dizis, the name by which these series are known in Turkey. The article briefly examines the cross-pollination that is taking place between the Turkish dizi, an already hybrid genre, and the Latin American telenovela. It suggests that these cross-cultural exchanges are fueling a renewal of the Latin American telenovela after years of decline. The article's analysis of the internationally successful melodrama ¿Qué culpa tiene Fatmagul? provides an in-depth example for the discussion. The paper explores the reasons why this telenovela in particular has resonated strongly with audiences all around Latin America.

Integrated CSP-PV hybrid solar power plant for two cities in Saudi Arabia

Solar energy has the potential to provide most of the electricity needed by mankind sustainably into the indefinite future. Concentrated Solar Power (CSP) has conventionally been considered more applicable than photovoltaic (PV) for baseload power since thermal storage is far cheaper than battery storage. However, the solar fields for CSP are relatively expensive. On the other hand, PV plants without storage deliver electric power at a much lower cost than CSP plants of comparable capacity without storage. Integrating both technologies is an attractive approach towards solar baseload power with affordable levelized cost of energy (LCOE). This study, which investigates the two cities of Saudi Arabia, consists of simulation and optimization in three main parts: The first part is a simulation of the CSP parabolic trough (CSP-PT) standalone plant and integrating the output parameters with an economic model to calculate the LCOE. The second part is the simulation of combined CSP-PT with PV, with a design strategy of utilizing all PV power for daytime use, and supplementing the PV output with thermal power as needed to maintain baseload operation in the daytime. The third part is the simulation of combined CSP-PT with a design strategy of providing all or nearly all daytime power with PV, with the utilization of excess energy from PV to supply heat to the thermal storage system. The results show that for a target capacity factor of 79%, the CSP plant alone requires a solar multiple of 6 in Riyadh and 3.5 in Tabuk. For both locations, the introduction of the hybrid concept substantially reduced the solar multiple. In Riyadh, the solar multiple ranged from 2.9 to 3 with the PV portion of the plant having a nameplate capacity equal to that of the CSP portion and 1.95 for a case with the PV nameplate capacity 60% greater than the CSP portion. For these same cases in Tabuk, the solar multiples were 1.78–1.85 and 1.6 simultaneously. Generally, hybridization is of greater benefit in Riyadh than in Tabuk owing to the greater fraction of solar resource in the form of diffuse sunlight which can be collected by the PV plant but not by the CSP plant. The LCOE was reduced by hybridization in both locations, but again the benefit was greater for Riyadh. Clearly, from a technological perspective, it is important to study the hybridization for an individual city based on its weather data as the incorporation of PV into CSP plant designs should be considered for all locations in order to reduce the cost to provide baseload power from solar energy, and the application of the hybridization concept can extend the applicability of CSP technology to regions with less direct sunlight than would be economically feasible with CSP alone.

Metropolitan Hybrid Identity in Nadia Hashimi’s A House Without Windows

The present article seeks to investigate the effect of colonial domination on Afghan society by analyzing Yusuf’s character in Nadia Hashimi’s A House Without Windows (2016). By theoretically framing the paper at Orientalism, the paper scrutinizes Hashimi’s approach to exemplify the concept of metropolitan hybridity through mimicry and Othering; how Yusuf internalizes the value of the colonizer and believes in the inferiority of his own culture. The paper analyses how Yusuf represents a colonialist ideology that reinforces the binary opposition of the West and East, a hybrid Afghan and the native Afghan. This article engages with debates around Orientalism and the construction of Western power that schematizes the inferiority of the East. It questions the strategies that are used to represent Yusuf as a hybrid Afghan, the strategies that help to produce an Orientalist discourse. The article signifies Yusuf’s imitation as a double articulation strategy: mimicking the Occident while disavowing and Other the native Afghans.

A postcolonial Pannenberg? Mimicry, the law, and the cross of love

AbstractThis paper employs the postcolonial concepts of mimicry and hybridity to interpret Wolfhart Pannenberg's understanding of the violence done to Jesus on the cross and the subversive reconciliatory love that it engenders. According to Pannenberg, although the man Jesus was crucified as blasphemer of the Jewish law, the resurrection vindicated Jesus so that the ones accusing Jesus were retroactively deemed to be the actual blasphemers. As a result, Jesus ended up dying not for his own alleged breaking of the law, but as an inclusive substitute for all blasphemers of God (through amour propre) deserving death. Thus, the resurrection confirmed Jesus’ divine identity and his earthly teaching that love supersedes and transforms the law. Applying the concept of mimicry to Pannenberg, on the cross the symbolic and semiotic are held together in tension for in mimicry the “not‐quite sameness” menaces the colonizer. The cross, ostensibly a symbolic sign of abjection, is mimicked by the suffering of Jesus and subverted through a practice of inclusive semiotic love which recapitulates sinful human life toward a life of transformed autonomy. Pannenberg displays a pseudo postcolonial understanding of subverting oppressive law into love. However, on account of his futurist ontology, the eschatological totality is underscored relative to formative experiences, leaving him vulnerable to postcolonial critiques of essentialism, which can reinscribe colonialism. I contend that Pannenberg employs a strategy of “strategic particularism” in which concepts such as mimicry and hybridity are helpful as hermeneutical tools but ultimately provisional and temporary relative to the whole.

A Study on the Effects of Hybridized Metal Oxide and Carbonaceous Nano-Cutting Fluids in the End Milling of AA6082 Aluminum Alloy

Finding an alternate solution for supplanting the existing conventional lubricant in machining is a challenge. This work narrows the search down to the use of nano-cutting fluids, as they exhibit excellent properties such as high thermal conductivity and good lubricity. A technical analysis of the performance of hybrid nano-cutting fluids in the end milling of AA6082 aluminium alloy in a constrained end milling condition is presented. Alumina and carbon nanotubes were chosen in this study for their better physical characteristics and compatibility during machining. Coconut oil was chosen as the base fluid (dispersal medium) as it provides good lubricity and better dispersion of nanoparticles due to its excellent rheological behaviour. The hybrid nanofluid was prepared by mixing alumina-based nanofluid with carbon nanotube nanoparticles in different volumetric concentrations. The thermo-physical properties of the prepared hybrid nanofluid were tested. Furthermore, they were tested for their spread-ability and other mechanical properties. Later, their performances as cutting fluid were studied with the minimum quantity lubrication (MQL) technique, wherein nanoparticle mist was formed and evaluated in the end milling of AA6082 aluminium to reduce the quantity of nanofluids’ usage during end milling. The controllable parameters of speed, feed rate, and type of cutting fluid were chosen, with the levels of cutting speeds and feed rate at 75–125 m/min, and 0.005–0.015 mm/tooth, respectively, and the response parameters studied were surface roughness and tool wear. The results show that better performance is achieved in hybridized nano-cutting fluid, with a sharp improvement of 20%, and 25% in tool wear and surface roughness when compared to the base fluid. This study has explored the concept of hybridization and the capability of nanofluids as cutting fluids that can be used as eco-friendly cutting fluids in manufacturing industries.

Trends of the Implementation of Hybrid Teaching and Learning in Mathematics Education: A Systematic Literature Review

Since the Covid-19 pandemic, the term hybrid is increasingly used as one of the efforts to solve problems related to constraints due to standard operating procedures. Unfortunately, the hybrid concept in teaching and learning is not discussed much there is a need to know the research trends to improve the teaching and learning process, especially in Mathematics education. Data were collected using a systematic literature review (SLR) method based on keywords in the leading data databases Scopus and WOS. A total of 41 final articles with full access within a period of five years (2018-2022) have been identified based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) involving four phases, namely identification, then screening, eligibility review and inclusion inspection. Trend findings show research that has a positive impact on hybrid teaching and learning based on the year of publication, research approach, country of the author, and purpose of the study. The implications of this study can improve the country's educational aspirations to improve the education system in line with industrial revolution 4.0 and provide valuable contributions to scholars or researchers with a critical evaluation of existing research. Further studies can be carried out through more in-depth studies and further developed by future researchers to determine the effectiveness of the implementation of hybrid teaching and learning that can be linked to Mathematics education.

A feasibility and dynamic performance analysis of hydromechanical hybrid power transmission technology for wind turbines

Abstract. A multi-body dynamical model of a wind turbine power generation system (WTPGS) based on hydromechanical hybrid power transmission (HMHPT) technology is developed and simulated to overcome the individual drawbacks of the gear train and hydrostatic power transmission (HPT) system. The HMHPT is a hybrid concept of a single-stage planetary gear train (SSPGT) and a typical HPT. The input shaft of the SSPGT is coupled with the turbine rotor, whereas the output shaft of the SSPGT is coupled with the shaft of a hydraulic pump. The hydraulic pump supplies flow to the hydro-motor, and its shaft is coupled with the generator. An existing turbine blade model of 750 kW based wind turbine is used for further development and analysis of the HMHPT. The simulation responses indicate that the power generation and the control potential both have been improved using the HMHPT in a wind turbine. Moreover, the influence on the motor power generation due to variations of pump and motor leakages is addressed. Additionally, it is found that if the order of the SSPGT and the HPT are swapped in the proposed HMHPT, then the settling time, maximum overshoot, and rise time of the system responses are increased. As a result, the controllability of the system is decreased.

It also describes the basic process of each segment and includes the relevant aspects of yard facilities and layout based on the previous literature. Furthermore, the shipyard capacity was analysed to explore the available resources in conventional shipyards to adapt ship recycling. Lastly, this article provides insight into the prospect of the hybrid concept to improve ship recycling yard competitiveness.

Content validity and psychometric properties of the inFLUenza Patient-Reported Outcome Plus (FLU-PRO Plus©) instrument in patients with COVID-19

PurposeA well-defined and reliable patient-reported outcome instrument for COVID-19 is important for assessing symptom severity and supporting research studies. The InFLUenza Patient-Reported Outcome (FLU-PRO) instrument has been expanded to include loss of taste and smell in the FLU-PRO Plus, to comprehensively cover COVID-19 symptoms. Our studies were designed to evaluate and validate the FLU-PRO Plus among patients with COVID-19.MethodsTwo studies were conducted: (1) a qualitative, non-interventional, cross-sectional study of patients with COVID-19 involving hybrid concept elicitation and cognitive debriefing interviews; (2) a psychometric evaluation of the measurement properties of FLU-PRO Plus, using data from COMET-ICE (COVID-19 Monoclonal antibody Efficacy Trial—Intent to Care Early).ResultsIn the qualitative interviews (n = 30), all 34 items of the FLU-PRO Plus were considered relevant to COVID-19, and participants determined the questionnaire was easily understood, well written, and comprehensive. In the psychometric evaluation (n = 845), the internal consistency reliability of FLU-PRO Plus total score was 0.94, ranging from 0.71 to 0.90 for domain scores. Reproducibility (Day 20–21) was 0.83 for total score, with domain scores of 0.67–0.89. Confirmatory factor analysis with the novel smell/taste domain demonstrated an acceptable fit to the data.ConclusionThe content, reliability, validity, and responsiveness of the FLU-PRO Plus in the COVID-19 population were supported. Our results suggest that FLU-PRO Plus is a content- and psychometrically-valid, fit-for-purpose measure which is easily understood by patients. FLU-PRO Plus is a suitable PRO measure for evaluating symptoms of COVID-19 and treatment benefit directly from the patient perspective.Trial Registration: ClinicalTrials.Gov: NCT04545060, September 10, 2020; retrospectively registered.

On General Class of Z-Contractions with Applications to Spring Mass Problem

One of the latest techniques in metric fixed point theory is the interpolation approach. This notion has so far been examined using standard functional equations. A hybrid form of this concept is yet to be uncovered by observing the available literature. With this background information, and based on the symmetry and rectangular properties of generalized metric spaces, this paper introduces a novel and unified hybrid concept under the name interpolative Y-Hardy–Rogers–Suzuki-type Z-contraction and establishes sufficient conditions for the existence of fixed points for such contractions. As an application, one of the obtained results was employed to examine new criteria for the existence of a solution to a boundary valued problem arising in the oscillation of a spring. The ideas proposed herein advance some recently announced important results in the corresponding literature. A comparative example was constructed to justify the abstractions and pre-eminence of our obtained results.

Health equilibrium in Korean adults with type 2 diabetes mellitus: A hybrid concept analysis.

The aim of the study was to provide a concept analysis of health equilibrium among patients with diabetes and introduced its operational definition. A concept analysis was conducted using a hybrid model of Schwartz-Barcott and Kim (Nursing research methodology: issues and implementations, Aspen, 1986). Using consolidated criteria for reporting qualitative research guidelines, 10 participants with diabetes mellitus were interviewed. Each participant conducted at least two interviews, with each interview session lasting approximately 20-60 min at home or in a quiet place with some privacy. Data were analysed using a grounded theory approach. The health equilibrium concept included four categories with 12 attributes: cognitive (commitment to health, willingness to make life adjustments, balanced awareness, maintaining control), social (social role performance, holding a social support system, participation in social relationships), behavioural (leading a balanced life, making efforts to maintain health, modulating overreaction diabetes) and psychological (hopefulness for a healthy life psychological stability) factors. Thus, health equilibrium was defined as a state in which remain committed to health, while maintaining a stable daily life, social relationships and psychological stability despite prejudices against the disease and self-care experiences. Health equilibrium for diabetes patients was defined as maintaining cognitive, social, behavioural and psychological equilibrium as a process of willingly adjusting to life with diabetes. This can help people with diabetes improve self-care and maintain social roles.

“People expect you to choose”: Postcolonial hybridity in complex geographies of scaled diaspora identities

Hybridity in geography, specifically hybridity through a postcolonial lens, is often removed from postcolonial origins regarding geographic scale. I argue that postcolonial hybridity is key to situating geographic scalar identity within the context of postcolonial diasporas navigating competing ideas of nationalism and regionalism. Postcolonial hybridity as opposed to hybridity as hyphenated identity, provides a historically contingent lens useful to contextualizing lived scalar identities within diaspora communities, particularly in the United States, a nation founded on settler colonial ideologies. Drawing from 3 years of observational and interview-based research in the US Indian Tamil diaspora, I argue that scalar identity is a directly influenced by colonial constructions of race, identity, and ideas of nationalism. Drawing from Bhabha’s (1994) concept of hybridity, I demonstrate how scalar identity can be reconceptualized with respect to postcolonial geographies of identity.

Performance study of an innovative concept of hybrid constructed wetland-extensive green roof with growing media amended with recycled materials

Implementation of green roofs requires a large amount of primary material, especially for constructing the growing media layer. In addition, irrigation of green roofs with potable water is uneconomical and unsustainable. The novel hybrid green roof system proposed in this paper is in line with the principles of circular economy as it incorporates recycled materials into green roof growing media and greywater for irrigation. Two experimental beds were built to evaluate the concept of treating greywater in a constructed wetland prior to using it to irrigate a dual-layer extensive green roof. The growing media in both two extensive green roof beds contained ca. 37.5% by volume of recycled crushed building rubble containing a large proportion of brick. One of the two beds additionally contained 9.5% by volume of sewage sludge-based biochar. The concept of the hybrid roof and novel growing media was evaluated based on laboratory analysis of the growing media and on onsite measurements of hydraulic and thermal performance. The growing media amended with recycled materials developed in this study had hydrophysical properties comparable to commercially available growing media without recycled materials. Observations made during one vegetation season from June to October and a ten day-intensive water quality monitoring campaign during September 2020 showed that the constructed wetland significantly reduced total nitrogen and orthophosphate concentrations in pre-treated greywater. Due to the irrigation method employed, in which water flowed predominantly through drainage mats below the growing media, nutrient-leaching by the irrigation water was avoided. Concentrations of nutrients in the effluent were observed to increase only in response to precipitation. The temperature peak of the bottom green roof layer was shifted by almost 9 h from the peak in air temperature, and temperature fluctuations were significantly reduced. Vegetation on the bed amended with biochar demonstrated more vigorous growth due to available nutrients in the biochar which increased the rate of temperature-reducing evapotranspiration. More water evapotranspirated more water, which provided more water retention capacity confirmed by a lower runoff coefficient. Simple storage routing hydraulic modeling of hybrid green roof runoff using a nonlinear reservoir was performed.

Mechanical Characterization of Aluminum Sandwich Structures with Woven-Ply Pineapple Leaf/Glass Fiber-Reinforced Hybrid Composite Core

ABSTRACT Fiber-metal laminates consisting of alternating metal and fiber-reinforced polymer layers have displayed remarkable performance in several engineering applications. This work aims to identify the feasibility of incorporating pineapple leaf fiber to partially supersede glass fiber in thermoplastic-based fiber-metal laminates. Fiber-metal laminates made of pineapple leaf/glass/polypropylene/aluminum were fabricated using the hot press molding technique. The tensile, flexural, Charpy impact and quasi-static indentation tests were performed. The findings indicated that the hybridization of glass with pineapple leaf fibers improved the mechanical properties of the laminates. The results are particularly promising in [G/P/G] laminates in which their tensile and flexural strengths are 38.98% and 20.19% higher than [P/P/P] laminates. In addition, the Charpy impact strengths of [G/P/G] laminates are also 236.66% and 175.68% greater than those of [P/P/P] laminates. In terms of indentation properties, the maximum indentation forces of [G/P/G] laminates are 16.71% and 13.76% higher than those of [P/P/P] laminates at indenter diameters of 12.7 and 20.0 mm, respectively. Interestingly, in-plane and out-of-plane properties of [G/P/G] laminates were comparable to [G/G/G] laminates. Thus, it is anticipated that the hybridization concept could escalate the utilization of natural fibers as a potential reinforcement for engineering applications.

Frictions and hybridity in Mozambique’s post-war peacebuilding: From civil war to precarious peace

ABSTRACT It has been about three decades since Mozambique transitioned from a brutal civil war and one-party rule to peace and democracy. Although Mozambique has not relapsed into another large-scale civil war, sustainable peace and democracy in the country have become ever more elusive. In 2013, military clashes between Renamo and the Frelimo-led government resumed and prompted a new peace process, whilst poverty and inequalities are rampant, authoritarianism is on the rise, and an Islamic insurgency erupted in the northern region. Accordingly, while some scholars still praise Mozambique’s post-war peacebuilding as successful, others have claimed that peacebuilding failed. This article evades the binary of successful or failed liberal peacebuilding in Mozambique. Instead, it applies the concepts of friction and hybridity to offer an alternative way of reading the 30 years of peace (building) in Mozambique. The article argues that frictions in values and interests between the international/liberal peacebuilders and local (non-liberal) elites have resulted in a negative and unstable hybrid peace, that is, a precarious peace in Mozambique.

Cripping hybrid futures

ABSTRACT In this collaboratively written article, we argue that disabled performers have long since questioned notions about physicality, subjectivity, temporality and spectatorship on stage that are currently being revisited in the debate on ‘hybrid’ theatre practices during the pandemic. Disability performances, as well as hybrid theatre formats, which are now booming due to the lockdown experience, provoke discussions and discursive negotiations about what theatre is, should be and for whom, and explore boundaries of the art form. Based on these arguments, we will examine the concept of hybridity, in order to critically explore the debate on hybrid theatre in relation to disability performance practices, using the examples of the internationally recognised performing artists Neil Marcus and Sins Invalid, and challenge notions of sustainability within that discourse. We end by asking what demands a hybrid future would need to meet to accommodate the diverse realities of non-normative bodyminds.
