Authors: Portela Mayda
Published: April 2021

El objetivo del presente trabajo fue evaluar las propiedades psicométricas de la escala de Funcionamiento Psicológico Positivo (FPP) en adolescentes uruguayos. La escala está compuesta por 33 ítems que miden 11 recursos psicológicos. El FPP se constituye en un constructo de segundo orden del bienestar eudaimónico. Se realizó un estudio de tipo instrumental con una muestra por conveniencia conformada por 183 adolescentes (de 12 a 17 años) de población general. Los resultados de los análisis factoriales realizados resultan en una estructura de siete dimensiones: autoestima, autonomía, propósito vital, optimismo/disfrute, curiosidad, humor, y dominio del entorno (RMSEA= .09, CFI= .99, TLI= .97), y adecuados valores de fiabilidad. La solución factorial organizada en siete factores explica el 62,15 % de la varianza. Estos resultados concuerdan con el único estudio publicado en población adolescente, que a diferencia del original y los posteriores replicados, utilizaron muestras de universitarios.

Treatment of Behcet disease (BD) is still considered challenging since no single agent has yet proved to reverse the underlying oxidative stress-induced inflammatory process. Zinc sulfate treatment has been shown to have an effective therapeutic outcome, however adequate exploration of the exact mechanism for its therapeutic benefit is still lacking. This study was carried out to assess and relate the oxidative stress parameters with the clinical manifestation index before and after oral zinc sulfate treatment. Twenty-five Behcet disease (BD) patients were recruited in the study besides an equal number of healthy individuals representing the control group. Patients were treated with 300mg/day oral zinc sulfate in three divided doses for one month. Blood samples were collected from the control group, patient group (before starting treatment),and treatment group (after zinc sulfate treatment) to measure serum oxidative stress parameters as well as antioxidant parameters. A dermatologist who was blind to the treatment calculated the clinical manifestation index (CMI) score and the oral ulcer parameters for each individual in the patient and treatment groups. Serum MDA, copper levels were found significantly higher in the patient group than in the control group. However, both parameters were considerably lower in the treatment group than in the patient group. Serum glutathione (GSH), zinc levels and RBC catalase activity were significantly lower in the patient group than in the control group, but they were substantially higher in the treatment group as compared to the patient group. The CMI score and oral ulcer parameters decreased significantly in the treatment group (after zinc sulfate treatment) compared to the patients’ group. The CMI demonstrated a significant positive correlation (P<0.01) with the oxidative stress parameters. In conclusion, BD patients were suffering from oxidative stress, the severity of which was directly proportional to the CMI score. The antioxidant activity of oral zinc sulfate treatment i

How COVID-19 reshapes businesses and executive pay for sustainability
Authors: Eklund Mehtap Aldogan , Stern Hermann J.
Published: April 2021

The purpose of this paper is to answer the research question of how to design a fair and resilient compensation scheme according to stakeholder theory and the sustainability concept. The first finding of this paper is the framework for the sustainable, fair, resilient, scientific, simple, and practical compensation schemes — pay for sustainability (P4S). P4S has been developed after reviewing the literature and obtaining insights from the compensation consultants in Switzerland. It is also a useful tool in COVID-19 and will be for future crises. As a second finding, this theory-adaptation-based conceptual and commentary paper criticizes the conventional executive compensation structure and introduces the business lessons learned from the COVID-19 crisis. As a contribution to both the literature and practice, this research advances the novel knowledge in the field by conceptualizing a reliable and scientific framework and explaining the advantages and disadvantages of the four methods of the P4S framework. During COVID-19, environmental, social, and governance (ESG) based performances and compensation schemes have gained more importance. Finally, these proposed methods contribute to the adaptation of ESG-based compensation schemes while considering the local and individual differences of organizations
La Funcionalidad del Derecho desde la Noción de Sistema
Authors: Ballesteros Romero Manuel Antonio
Published: April 2021

El punto de partida es la doble opción de abordar el estudio del derecho. De un lado la división mecanicista, que conduce a plantear el derecho como algo puro, al que no se le puede relacionar con las ciencias naturales ni sociales. De otro lado, la visión sistémica, que implica comprender el objeto de estudio en interrelación con el entorno. Se toma partida por la segunda, enfrentando los pensamientos puristas a favor de una visión del objeto de estudio, no como algo que yace en el espacio, sino como algo dinámico, que se manifiesta en el tiempo y se comporta como proceso, que hace parte de ese entorno constituyendo un sistema mayor, y que por la consideración de proceso, elementos del entorno pasan a hacer parte de ese sistema y elementos del sistema pasan a hacer parte del entorno, y que tanto el entorno determina al sistema como el sistema al entorno. El derecho es considerado no como parte del sistema social, sino como una dimensión de dicho sistema y, por ello, inseparable del sistema social; pero, además, tanto el derecho como la sociedad tienen, y requieren para existir, un sustrato donde se encuentran los seres humanos como entidades biológicas, los recursos naturales y el planeta. Por consiguiente, si bien no se puede confundir el sistema social en tanto sistema comunicacional con la agrupación de seres humanos ni con el espacio físico donde existen los seres humanos, no se puede perder de vista que ese sistema físico constituye el sustrato del sistema comunicacional; siendo la cosa en sí, de la cual el sistema social es el fenómeno o el como sí, un mundo construido a partir de la representación del mundo físico.
Conventional wisdom on roosting behaviour of Australian flying foxes - a critical review, and evaluation using new data
Authors: Lunn Tamika , Eby Peggy , Brooks Remy , McCallum Hamish , Plowright Raina , Kessler Maureen , Peel Alison
Published: April 2021

1. Fruit bats (Family: Pteropodidae) are animals of great ecological and
economic importance, yet their populations are threatened by ongoing
habitat loss and human persecution. A lack of ecological knowledge for
the vast majority of Pteropodid bat species presents additional
challenges for their conservation and management. 2. In Australia,
populations of flying-fox species (Genus: Pteropus) are declining and
management approaches are highly contentious. Australian flying-fox
roosts are exposed to management regimes involving habitat modification,
either through human-wildlife conflict management policies, or
vegetation restoration programs. Details on the fine-scale roosting
ecology of flying-foxes are not sufficiently known to provide
evidence-based guidance for these regimes and the impact on flying-foxes
of these habitat modifications is poorly understood. 3. We seek to
identify and test commonly held understandings about the roosting
ecology of Australian flying-foxes to inform practical recommendations
and guide and refine management practices at flying-fox roosts. 4. We
identify 31 statements relevant to understanding of flying-fox roosting
structure, and synthesise these in the context of existing literature.
We then contribute contemporary data on the fine-scale roosting
structure of flying-fox species in south-eastern Queensland and
north-eastern New South Wales, presenting a 13-month dataset from 2,522
spatially referenced roost trees across eight sites. 5. We show evidence
of sympatry and indirect competition between species, including spatial
segregation of black and grey-headed flying-foxes within roosts and
seasonal displacement of both species by little red flying-foxes. We
demonstrate roost-specific annual trends in occupancy and abundance and
provide updated demographic information including the spatial and
temporal distributions of males and females within roosts. 6. Insights
from our systematic and quantitative study will be important to guide
evidence-based recommendations on restoration and management and will be
crucial for the implementation of priority recovery actions for the
preservation of these species into the future.
The plasma membrane-associated Ca2+- binding protein PCaP1 is required for oligogalacturonide and flagellin-induced priming and immunity

Published: April 2021

Early signaling events in response to elicitation include reversible
protein phosphorylation and re-localization of plasma membrane (PM)
proteins. Oligogalacturonides (OGs) are a class of Damage-Associated
Molecular Patterns (DAMPs) that act as endogenous signals to activate
the plant immune response. Previous data on early phosphoproteome
changes in Arabidopsis thaliana upon OG perception uncovered the
immune-related phospho-regulation of several membrane proteins, among
which PCaP1, a PM-anchored protein with actin filament-severing
activity, was chosen for its potential involvement in OG- as well as
flagellin-triggered responses. Here we demonstrate that PCaP1 is
required for late, but not early, responses induced by OGs and
flagellin. Moreover, pcap1 mutants, unlike the wild type, are impaired
in the recovery of full responsiveness to a second treatment with OGs
performed 24 h after the first one. Localization studies on PCaP1 upon
OG treatment in plants expressing a functional PCaP1-GFP fusion under
the control of PCaP1 promoter revealed fluorescence on the PM, organized
in densely packed punctate structures, previously reported as
microdomains. Fluorescence was found to be associated also with
endocytic vesicles, the number of which rapidly increased after OG
treatment, suggesting both an endocytic turnover of PCaP1 for
maintaining its homeostasis at the PM and an OG-induced endocytosis.

Published: April 2021

Aim: Dapagliflozin improves glycaemic control in patients with type 2
diabetes mellitus (T2DM) and is approved in European and Japanese
patients with type 1 diabetes mellitus (T1DM) with inadequate glycaemic
control. The objectives of this work were to characterise the
dapagliflozin pharmacokinetics (PK) in patients with T1DM, assess the
influence of covariates on dapagliflozin PK, and compare dapagliflozin
systemic exposure between patients with T1DM and T2DM. Methods:
Population PK analysis was performed using a non-linear mixed-effect
modelling approach. The analysis included 5,793 dapagliflozin plasma
concentrations from 1,150 adult patients with T1DM, collected from one
phase 2 (NCT01498185) and two phase 3 studies (DEPICT-1, NCT02268214;
DEPICT-2, NCT02460978). Covariate effects were investigated using
stepwise covariate modelling. Model-derived area under the
concentration-time curve (AUC) was compared with AUC in patients with
T2DM. Results: The final two-compartmental model adequately described
the dapagliflozin concentrations in patients with T1DM. The estimated
apparent clearance was 20.5 L/h. Model-predicted systemic exposure for 5
mg and 10 mg of dapagliflozin indicated dose-proportionality and was
comparable between patients with T1DM and T2DM. The identified covariate
relationships showed that patients with better renal function (measured
as estimated glomerular filtration rate), males, and heavier patients
had lower dapagliflozin systemic exposure. Among the covariates studied,
no covariates affected dapagliflozin systemic exposure to a clinically
relevant extent. Conclusions: Dapagliflozin PK in patients with T1DM was
adequately described by the population PK model and no clinically
relevant covariates were identified. Dapagliflozin systemic exposure was
comparable between patients with T1DM and T2DM. NCT01498185,

Published: April 2021

Conservation of large carnivores like leopards requires large and
interconnected habitats. Despite the wide geographic range of the
leopard globally, only 17% of their habitat is within protected areas.
In Nepal, leopards are distributed widely across the country but their
status is not adequately studied which compromised the necessary
conservation attention for the species. This study carried out
sign-based occupancy survey across the Chure (the Himalayan foothills)
range (~19,000 km2) to understand the habitat occupancy
of leopards along with the covariates affecting their presence. The
model-averaged leopard occupancy in the Chure range was 0.5732 (0.0082
SD) with a detection probability of 0.2554 (0.1142 SE). The top model
included wild boar, ruggedness, presence of livestock and human
population density as covariates. The β coefficient estimate from the
model indicated the wild boar was the primary covariate contributing
positively to the leopard occupancy followed by the presence of
livestock, ruggedness and human population density. The detection
probability of leopard was higher outside the protected areas, less in
the densely vegetated areas, and higher in the area where there is a
presence of livestock. Enhanced law enforcement and mass awareness
activities are necessary to reduce poaching/killing of wild ungulates
and leopard in the Chure range and to increase leopard occupancy. In
addition, maintaining a sufficient natural prey base can contribute to
minimize the livestock depredation and hence, decrease the human-leopard
conflict in the Chure range.

Hexagonal chains are a special class of catacondensed benzenoid system
and phenylene chains are a class of polycyclic aromatic compounds.
Recently, A family of Sombor indices was introduced by Gutman in the
chemical graph theory. It had been examined that these indices may be
successfully applied on modeling thermodynamic properties of compounds.
In this paper, we study the expected values of the Sombor indices in
random hexagonal chains, phenylene chains, and consider the Sombor
indices of some chemical graphs such as graphene, coronoid systems and
carbon nanocones.
Pollinator-Mediated Selection on Floral Traits in the Arctic Plant Parrya nudicaulis (Brassicaceae)
Authors: Carlson Matthew , Fulkerson Justin
Published: April 2021

The evolution of floral traits is largely attributed to
pollinator-mediated selection; however, the importance of pollinators as
selective agents in pollen-limited environments is poorly resolved. In
pollen-limited arctic and subarctic regions, selection is expected to
either favor floral traits that increase pollinator attraction or
promote reproductive assurance through selfing. We quantified phenotypic
selection on floral traits in two arctic and two subarctic populations
of Parrya nudicaulis. Additionally, we measured selection in plants in
both open-pollination and pollen-augmentation treatments to estimate
selection imposed by pollinators in one population. Seed production was
found to be limited by pollen availability and strong directional
selection on flower number was observed. We did not detect consistently
greater magnitudes of selection on floral traits in the arctic relative
to the subarctic populations. Directional selection for more pigmented
flowers in one arctic population was observed however. In some
populations, selection on flower color was found to interact with other
traits. We did not detect consistently stronger selection gradients
across all traits for plants exposed to pollinator selection relative to
those in the pollen-augmentation treatment; however directional
selection tended to be higher for some floral traits in open-pollinated
plants.
Deviation From Delivery Of Radiation Therapy To Childhood Cancer Patients: A Retrospective Audit
Authors: Agrawal Rashi , Goel Vineeta , Anand Anil , Arora Ramandeep
Published: April 2021

Background The delivery of Radiation therapy (RT) needs a level of
coordination and planning which can be challenging in resource-limited
settings. In this retrospective study we describe the profile of
children undergoing radiation and analyze deviation from accepted norms.
Procedure Data on all children (< 18 years age) with cancer
who completed RT from Jan 2009 to Dec 2019 were retrieved. Diagnostic
groups with more than 5 patients, were included in the analysis for
deviations in RT (Time to start (TTS); total dose delivered (TDD) in
Grays; and time to complete (TTC)). We investigated reasons for
deviation. Results 207 received RT as front-line treatment (68% Indian,
59% male and 32% received treatment preceding RT outside). Most common
diagnosis were brain tumors (44%), lymphoma (13%). leukemia and soft
tissue sarcoma (10% each). 23.6% had deviation in TTS, 6.0% in TDD
and 24.7% in TTC while 43.4% had at least one deviation in any of
these three parameters. Deviation in TTS varied significantly by
location of preceding treatment and by cancer (greatest deviation in
sarcomas) with issues around access to healthcare the most common
reason. Deviation in TTC varied significantly by cancer (greatest
deviation in sarcomas and medulloblastoma) with myelotoxicity the most
common reason. Conclusions Our study adds to the limited literature on
RT quality for children with cancer in LMIC. Certain cancers (sarcomas
and medulloblastoma) and patient groups (preceding treatment outside our
institute) had the maximum deviation. Barriers to accessing care and
myelotoxicity were the two main reasons for this deviation.
Interleukin-17A (IL-17A): the silent amplifier of COVID-19
Authors: Maione Francesco , Casillo Gian , Raucci Federica , Bucci Mariarosaria
Published: April 2021

One of the hallmarks of COVID-19 is the cytokine storm that provokes
primarily pneumonia followed by systemic inflammation. Emerging evidence
has identified a potential link between elevated levels of
interleukin-17A (IL-17A) and disease severity and progression.
Considering that per se IL-17A can activate several inflammatory
pathways, it is plausible to hypothesize an involvement of this cytokine
in COVID-19 clinical outcomes. Thus, this cytokine can represent a
marker of disease progression and/or a target to develop therapeutic
strategies. This hypothesis paper aims to propose this “unique”
cytokine as a silent amplifier of the COVID-19 immune response and
(potentially) related therapy.

Published: April 2021

O objetivo do estudo é identificar os procedimentos utilizados por hospitais privados brasileiros na gestão de custos ambientais. Aplicou-se uma pesquisa do tipo survey, composta por assertivas com escalas do tipo Likert de cinco pontos, cujo instrumento foi encaminhado aos respectivos contadores e gerentes da área ambiental de 1.188 hospitais. Os dados de 101 hospitais (8,5% da população) foram coletados em outubro/2017 e foram analisados por meio de estatística descritiva e as hipóteses oriundas da literatura foram testadas pelo modelo de Mann-Whitney, pelo coeficiente de Spearman e pelo modelo de regressão linear múltipla. Os resultados apontam que, em geral, nos hospitais há pouca contabilização e utilização de práticas de gestão de custos ambientais. Os contadores evidenciam pouco conhecimento em contabilidade ambiental. Nos hospitais pesquisados a gestão dos custos ambientais não é tratada de forma estratégica, limitando-se apenas a cumprir a legislação. Não foi possível identificar a existência de relacionamento entre o controle de custos ambientais e o desempenho econômico dos hospitais. Verificou-se, estatisticamente, que os hospitais de maior porte são aqueles que apresentam maior volume de investimentos nas questões ambientais e maior controle dos custos ambientais. Constatou-se que o tema é ainda incipiente nos hospitais pesquisados.

Published: April 2021

Driven by a continuing debate about the management accounting career evolution and the influence of instructional strategies on student performance, this study focuses on active learning strategies in managerial accounting courses. Based on Kolb’s experiential learning theory, a quasi-experiment was developed to assess the effect of a guided aviation manufacturing hands-on team-based case in teaching standard costing to business administration majors. Evidence was gathered from four cohorts of a cost accounting undergraduate course in a large public research university in Brazil. A total of 219 students participated in the study. The instructor taught all groups under identical conditions on a weekly basis. Data processing included descriptive statistics, a paired test (experimental hypothesis), and wordclouds. In addition, experts (faculty in the field) validated the results. Results are robust (Cohen’s d of 1.026) and indicate that the experimental group demonstrate significant pre- to post-test improvement in exam performance, compared to the control group, with a large effect size. Contributions of the study aimed at transferring learning that favors students approach to real life and the development of social skills (student builds, interacts and manages an activity working in teams); a positive experience that may encourage faculty and program administrators to use more active instructional strategies; and preparing the students for the market, developing professionals with demanded working skills.

Published: April 2021

Schizophrenia is a severe mental illness that affects people all around the world. It presents in many different contexts, across geographic boundaries, and in different ways. Rates of schizophrenia seem generally to be the same regardless of geographical location, though there is some evidence that those in developed nations have a higher incidence of the disorder. Also, immigrants who relocate to areas where their culture has little, or no representation are at more risk for schizophrenia. While the prevalence of schizophrenia is similar around the world, the presentation of the disorder can vary widely, depending on the cultural, religious, and supernatural beliefs native to specific areas. Examples of varying types of presentation of schizophrenia, including culture-bound disorder variants, can give insight into the ways in which people from across the world make sense of this devastating disease, and ways in which they attempt to treat it.

Let p(z) = ?n?=0 a?z? be a polynomial of degree n, M(p,R) := max|z|=R?0
|p(z)|, and M(p,1) := ||p||. Then according to a well-known result of Ankeny
and Rivlin, we have for R ? 1, M(p,R) ? (Rn+1/2) ||p||. This inequality has
been sharpened among others by Govil, who proved that for R ? 1, M(p,R) ? (Rn+1/2) ||p||-n/2 (||p||2-4|an|2/||p||) {(R-1)||p||/||p||+2|an|- ln (1+
(R-1)||p||/||p||+2|an|)}. In this paper, we sharpen the above inequality of
Govil, which in turn sharpens inequality of Ankeny and Rivlin. We present
our result in terms of the LerchPhi function ?(z,s,a), implemented in
Wolfram's MATHEMATICA as LerchPhi [z,s,a], which can be evaluated to
arbitrary numerical precision, and is suitable for both symbolic and
numerical manipulations. Also, we present an example and by using MATLAB
show that for some polynomials the improvement in bound can be considerably
significant.

POLITICAL ECOLOGY OF THE GLOBAL SOUTH: THE AMAZON FUND
Authors: Souza Guilherme Fernando Ferreira de
Published: April 2021

As a multidimensional field, development encompasses a variety of disciplines and schools of thought. It has been evolving throughout history with different definitions and approaches being utilized and continues to evolve as new elements are integrated. The environmental and temporal dimensions gained significant prominence in the 21st century, therefore the concept evolved to be also frequently mentioned as sustainable development. The following definition was used during the General Assembly of the United Nations in 2015: “Sustainable development recognizes that eradicating poverty in all its forms and dimensions, combating inequality within and among countries, preserving the planet, creating sustained, inclusive and sustainable economic growth and fostering social inclusion are linked to each other and are interdependent”. Political ecology is a scientific field closely connected to the development agenda, as its ultimate goal is to promote sustainable development. With a focus on participatory methods, stakeholder networks and root causes, it provides a systemic perspective to human-environment systems. Another important benefit is that it promotes the connection between science and policy-making. From the political ecology perspective, this paper analyses the Amazon Fund, an initiative implemented by the Brazilian Government in 2009 to promote sustainable development. In the following years after the implementation of the Amazon Fund, considerable decrease in deforestation was observed at the Brazilian part of the Amazon Forest, including a record low in 2012, indicating the effectiveness of the project. Among the main results, the paper calls for strengthened environmental governance, the promotion of adaptative and multilevel approaches to governance and data and information generation for sustainable development.

Published: April 2021

The significant concentration of the world agricultural matrix in polluting sources and with prices subject to instabilities, such as pesticides, has increased the search of countries for alternative agroecological techniques, including urban gardens, as a way of increasing food and nutritional security in the country. population. Thus, through bibliographic research, the objective of this work consists of a descriptive narrative about the potential of urban agriculture, by studying the evolution, challenges and perspectives, consolidating itself in the Brazilian agroecological matrix and contributing in the long run to greater decentralization of food production with less dependence on pesticides. In this sense, Brazil, benefited by natural factors, has favorable conditions for the exploitation of this form of agriculture and experiences great evolution, with urban gardens being among the fastest growing in the country and being one of the most competitive sources of the Brazilian agroecological matrix. However, the need for incentive policies, awareness of the population, planning of farming spaces in urban environments, in addition to creating a new incentive policy for urban agriculture and making greater investments in research and development appear as important objectives to be achieved so that urban gardens can, in fact, consolidate themselves on the national scene.

Published: April 2021

In a context of growing customer needs and requirements and worsening environmental issues, the Product Development Process must adapt to these circumstances, promoting measures that enable sustainable development, thus maintaining balance and synergy in the environmental, social and economic spheres. For this, it is essential to carry out the pre-development of business proposals. In this context, adopting a holistic approach that interrelates various areas of literature, brings together contributions in order to lead society to a resilient and resource-efficient environment. Thus, this research promotes the interrelationship between the Product Development Process and the Sustainable Development Goals and aims to realize the pre-development of a product under the perspective of the Sustainable Development Goals (SDG). To meet the proposed objective, the methodology adopted consists of the adaptation of a pre-development model, selected through bibliographic analysis. The results of this research present the pre-development of a product willing to meet the goals of SDG 6 (drinking water and sanitation) and SDG 7 (accessible and clean energy). It highlights the use of tools to structure and ensure the assertiveness of the proposal, such as IDEF0, SWOT analysis and FMEA.

Published: April 2021

Sustainable urban mobility adds a new dimension to the circulation of goods and people in the city: sustainability. The increasing number of individual motor vehicles is an accurate urban mobility diagnostic, by highlighting strengths and weaknesses, to guide public policies aimed at improving the quality of urban life. In this paper, the Sustainable Urban Mobility Index has been discussed and then applied to evaluate the sustainable urban mobility in Campinas (SP, Brazil). For the period 2010-2014, the index shows a persistent insufficiency in the sustainable urban mobility of this city, even if there was a slight improvement in the period. This is due to the environmental dimension, considering the increasing fuel consumption. It is therefore necessary to look for possible solutions involving primarily collective transportation and non-motorized one, especially for short distance.

Published: April 2021

The special-shaped column structure system has more advantages than the rectangular column system in terms of architectural design and actual use. As a relatively new structural form, the concrete special-shaped column structure has not accumulated enough engineering practical experience. In this study, the rotation-moment curve of the plastic hinge of special-shaped column frame element was defined, the coupled PMM hinge applied to the frame element was studied, and the yield surface of the hinge was drawn. On this basis, an elastoplastic pushover analysis was conducted on a 12-storey special-shaped column frame model, its failure under different earthquakes was simulated, and its seismic performance was studied. The work of this article can provide reference for the engineering application of special-shaped column frame structure.

The Open Shop Problem is a Production Scheduling problem where jobs do not have predestined processing routes, which increases the solution space and, therefore, the complexity of the problem. This work proposes a novel mathematical model that addresses the Open Shop theme with worker flexibility and no-wait. We consider the resource constraint of flexible and multiskilled labor. That is, the workers can execute their activities in more than one workstation. Simultaneously, the latter the continued production is contemplated, which hinders the reachability of feasible solutions and therefore increases the problem complexity. To validate the model, we generate several benchmarks, and the results obtained highlight the importance of worker flexibility in achieving greater problem feasibility.

Bu çalışmada, Seyhan Nehri’nden sağlanan ekosistem hizmetlerine yönelik bakış açılarının Q metodoloji yardımıyla değerlendirilmesi amaçlanmıştır. Analizler sonucunda konuya yönelik iki farklı bakış açısı belirlenmiş, katılımcıların %80’i 1 nolu faktörde, %20’si 2 nolu faktörde yer almıştır. 1 Nolu faktörde üzerinde hemfikir olunan başlıca ifade “Seyhan Nehri tarımsal sulama için kaynak sağlar.” olmuştur. Bu sonuç, Türkiye ve bölge tarımı için büyük önem taşıyan Çukurova’yı besleyen Seyhan Nehri’nden sağlanan hayatî yararlara yönelik yüksek bir farkındalık söz konusu olduğunu işaret etmektedir. 2 Nolu faktörde bir araya gelen katılımcıların üzerinde en çok birleştikleri ifadeler incelendiğinde, en üst sırada “Seyhan Nehri sosyal etkileşim için uygun olmayan ortamlar sunar.” ifadesinin yer aldığı görülmüştür. Genel olarak, Seyhan Nehri’nden sağlanan ekosistem hizmetlerine yönelik olarak 1 nolu faktördeki katılımcıların olumlu, 2 nolu faktördeki katılımcıların ise olumsuz görüş geliştirdiklerini söylemek mümkün bulunmaktadır. Q metodoloji ile yapılacak çalışmaların, insanların bakış açılarını belirlemeye yönelik araştırmalarda, plancıların ve yöneticilerin çalışmalarını daha verimli hale getirmelerinde önemli bir araç olduğu bu çalışma ile ortaya konulmaya çalışılmıştır. Çalışma ile elde edilen verilerin, ülkemizde Q metodoloji ile ilgili yapılacak çalışmalara örnek teşkil etmesi, Seyhan Nehri’ne yönelik gerçekleştirilecek doğa koruma ve kaynak yönetimi faaliyetlerine ışık tutması beklenmektektedir.

Yeşil alanlar sadece kent insanının doğaya olan özlemini gidermekle kalmaz, aynı zamanda kentsel yaşamın olumsuz yönlerini de iyileştirmektedir. Bu anlamda, yeşil alanlardan parkların kullanımının detaylı bir şekilde incelenmesi büyük önem taşımaktadır. Bu çalışmanın amaçları, Burdur halkının kentte yer alan parkları kullanım durumlarını ortaya koymak, Burdur halkının parkların yeterlilikleri konusundaki görüşlerini ve parklar konusundaki beklentilerini belirlemektir. Bu amaçla, anket yöntemi kullanılmıştır. Katılımcıların çoğu parkları yaz mevsiminde arkadaşıyla ziyaret ettiklerini, parklara yürüyerek ulaştıklarını ve parkta 1-2 saat zaman harcadıklarını belirtmişlerdir. Cumhuriyet parkı katılımcılar tarafından en çok ziyaret edilen ve en çok beğenilen park olmuştur. Katılımcıların %65’i Burdur kentinde bulunan park sayısını yeterli bulmuştur. Katılımcılar mahallelerindeki parklarda bisiklet parkı, çocuk oyun alanı, futbol sahası, çay ocağı, yürüyüş parkuru, spor aletleri, çeşme gibi eksikliklerin olduğunu ifade etmişlerdir. Kent insanının mahalle parklarından yeterince tatmin olmadığı sonucuna ulaşılmıştır. Bu husus, ilgili kurumlar tarafından detaylı şekilde ele alınmalı ve söz konusu tatminsizliğin giderilmesi için çalışmalara hız verilmelidir.

Published: April 2021

Kentlerde bireylerin açık ve yeşil alanlardan eşit olarak faydalanmasını öngören kapsayıcı tasarım yaklaşımı, erişilebilirliğin sağlanması için değerlendirilmesi gereken önemli bir konudur. Günümüzde kentlerde araç kullanımının artması, toplu taşıma kullanımlarının ve yürünebilirliğin azalması nedeniyle, erişilebilirlikle ilgili sorunlar ortaya çıkmaktadır. Kentlerde ortaya çıkan bu sorunları çözümleyebilmek için erişilebilirliği destekleyen kapsayıcı tasarım kriterlerinin farklı örneklemlerde karşılaştırmalı olarak irdelenmesine ihtiyaç vardır. Erişilebilirliğin değerlendirilmesine yönelik tasarım kriterlerinin geliştirildiği pratik bir model üretilmesi kentlerin sürdürülebilirliği için önemlidir. Bu araştırmanın amacı, Çankırı kentinde kapsayıcı tasarım kriterlerini değerlendirerek erişilebilirlik durumunu analiz etmek ve bu kapsamdaki sorunları ortaya koyarak öneriler geliştirmektir. Çalışma alanı olarak kentin yoğun kullanıma sahip kamusal alanlarının yer aldığı Çankırı kent merkezi seçilmiştir. Araştırmanın ilk aşamasında mekân dizimi (space syntax) yöntemiyle alanın fiziksel erişilebilirlik durumu analiz edilmiştir. İkinci aşamada kapsayıcılık anlayışının mekânsal parametreleri olarak sınıflandırılan bazı çoklu kentsel tasarım kriterleri gözlem ve arazi çalışmasına dayalı bir analiz aracılığı ile değerlendirilmiştir. Sonuçta, Çankırı kent merkezinin fiziksel erişilebilirliği destekleyen gridal sistem dokusuna sahip olduğu saptanmış olsa da mekânsal kaliteyi gösteren kapsayıcı tasarım kriterlerine dair eksikler nedeniyle erişilebilirlik kapasitesinin düştüğü ortaya çıkmıştır. Araştırma sonunda kentte kapsayıcı tasarım kriterlerindeki sorunlara yönelik öneriler geliştirilmiştir. Elde edilen araştırma sonuçlarının diğer kentlerde de değerlendirilmesi ve geliştirilmesi gelecekte ortaya çıkan sorunların çözümüne ve yerel bilgi havuzuna katkı sağlayacaktır.

Published: April 2021

Çalışmada Türkiye mobilya sektörü dış ticaretinin zaman serileri yöntemi olan ARIMA kullanılarak 2028 yılına kadar tahmini amaçlanmıştır. 1969-2018 yıllarına ait Türkiye mobilya sektörü dış ticaret değerlerinden yararlanılmış, bu veriler Dünya Bankası (WGB) dolar defletörü ile çarpılarak, 2010 bazlı değerler ile tahminleme yapılmıştır. Dış ticaret verileri deflatörle 2010 bazlı reel hale getirildikten sonra yapılan tahmin işlemindeki verilerin artışları veya azalışları arasında düzensizlikler göze çarpmaktadır. Eldeki verileri düzenlemede logaritma alma işlemi yapılmıştır. Zaman serileri analizinde üç ayrı ARIMA modeli uygun görülerek, karşılaştırmalara bağlı olarak bulgular elde edilmiştir. Bu reel değerli tahminler incelendiğinde ihracat değerlerinin düşüş eğiliminde olduğu görülmektedir. İthalat tahmini için yapılan ARIMA modeline ait veriler incelendiğinde değerlerde artış olduğu gözlenmektedir.

Published: April 2021

In this study, the success of different satellite images and classification approaches in land cover (LC) classification were compared. A total of six satellite images, including two passive (Landsat 8 OLI (L8) and Sentinel-2 (S2)) satellite images and four fused satellite images from active (Sentinel-1(S1)-VH and VV polarization) and passive satellite images (L8-S1-VH, L8-S1-VV, S2-S1-VH and S2-S1-VV) were used in the classification in the study. For this purpose, L8, S2, L8-S1-VH, L8-S1-VV, S2-S1-VH and S2-S1-VV satellite images were classified according to three ((Maximum Likelihood Classification (MLC), Support Vector Machine (SVM) and Artificial Neural Networks (ANN)) different image classification approaches using the forest cover types map as gorund data. The results obtained from classification methods were evaluated based on overall accuracies (OA) and kappa coefficients (KC). When the classification successes obtained from the three classification methods are evaluated, it was observed that the KC ranged from 0.66 to 0.95 and the OA ranged from 76.82% to 96.67. The results indicated that the highest OA was displayed by MLC (ranged 85.33% to 96.67%), closely followed by SVM (ranged 80.11% to 91.93%), and ﬁnally ANN (ranged 76.82% to 89.92%). In addition, a comparison of classification performance using three utilized classification algorithms was performed. The S1-VH; S1-VV and, S2 and L8 fused images classified with an MLC algorithm produce the most accurate LC map, indicating an OA of 92.00%, 94.00%, 96.67%, 93.33% and a KC of 0.90, 0.93, 0.95, 0.92 for S2 and L8, respectively. Thus, it can be concluded that fused of satellite images improve the accuracies of LC classification.

In this study, the differences in terms of the fiber morphology and the chemical composition between the heartwood and sapwood of red gum (Eucalyptus camaldulensis Dehnh.), black willow (Salix nigra Marsh.), and oriental beech (Fagus orientalis Lipsky) were investigated. The results showed that the heartwood samples had shorter fibers and lower slenderness ratios than those of the sapwood samples. The differences in the vessel element length of the heartwood and sapwood of sampled tree species were statistically insignificant. The heartwood samples had less holocellulose and more klason lignin content. In addition, the ethanol, hot water, and cold water solubility values in heartwood samples were higher. The other morphological and chemical properties of the heartwood and sapwood depended on the tree species.

PENDIDIKAN AGAMA ISLAM (PAI) MULTIKULTURAL PERSPEKTIF PEMBELAJARAN INTEGRATIF
Authors: Saepudin Mashuri
Published: April 2021

Tulisan ini mengkaji tentang PAI multikultural sebagai model pembelajaran integratif yang memadukan antara ilmu pengetahuan dan agama. Dari aspek konten, multikulturalisme mengkaji keragaman bangsa, suku, warna kulit, bahasa, agama dan keragaman lain yang terbentang dalam realitas sosial kehidupan manusia sebagai ayat-ayat Allah yang bersifat kauniyah. Sedangkan PAI mempelajari normativitas ajaran Islam dan dimensi historis yang banyak termuat dalam al-Qur’an sebagai ayat-ayat Allah yang bersifat qauliyah. Pembelajaran kedua bidang keilmuan tersebut sama-sama sebagai proses pencarian kebenaran yang merujuk kepada Allah sebagai episentrum kebenaran Hakiki dan sumber ilmu pengetahuan. Dari konsep pembelajaran integratif yang dikemukakan pemikir Islam dan Barat, PAI multikultural berada pada pola relasi antardispliner, yaitu integrasi antara ilmu umum dan ilmu agama. PAI multikultural sebagai pembelajaran integratif tergambar pada aspek: tujuan, materi, metode, media dan sumber belajar dan penilaian yang saling terintegrasi dalam membentuk kompetensi beragama peserta didik secara integral, yaitu: keterpaduan antara unsur duniawi dan ukhrawi, antara dimensi spritual dan intelektual, antara ranah personal dan sosial dalam konteks membangun harmoni kehidupan warga sekolah, masyarakat dan bangsa Indonesia yang pluralistik dari segala aspeknya.
