The paper presents the results of a comparison of water turbidity and suspended particulate matter concentration (SPM) obtained from quasi-synchronous in situ and satellite remote-sensing data. Field measurements from a small boat were performed in April and May 2019, in the northeastern part of the Black Sea, in the mouth area of the Mzymta River. The measuring instruments and methods included a turbidity sensor mounted on a CTD (Conductivity, Temperature, Depth), probe, a portable turbidimeter, water sampling for further laboratory analysis and collecting meteorological information from boat and ground-based weather stations. Remote-sensing methods included turbidity and SPM estimation using the C2RCC (Case 2 Regional Coast Color) and Atmospheric correction for OLI ‘lite’ (ACOLITE) ACOLITE processors that were run on Landsat-8 Operational Land Imager (OLI) and Sentinel-2A/2B Multispectral Instrument (MSI) satellite data. The highest correlation between the satellite SPM and the water sampling SPM for the study area in conditions of spring flooding was achieved using C2RCC, but only for measurements undertaken almost synchronously with satellite imaging because of the high mobility of the Mzymta plume. Within the few hours when all the stations were completed, its boundary could shift considerably. The ACOLITE algorithms overestimated by 1.5 times the water sampling SPM in the low value range up to 15 g/m3. For SPM over 20–25 g/m3, a high correlation was observed both with the in situ measurements and the C2RCC results. It was demonstrated that quantitative turbidity and SPM values retrieved from Landsat-8 OLI and Sentinel-2A/2B MSI data can adequately reflect the real situation even using standard retrieval algorithms, not regional ones, provided the best suited algorithm is selected for the study region.

Published: January 2021

The spatial distribution of forest stands is one of the fundamental properties of forests. Timely and accurately obtained stand distribution can help people better understand, manage, and utilize forests. The development of remote sensing technology has made it possible to map the distribution of tree species in a timely and accurate manner. At present, a large amount of remote sensing data have been accumulated, including high-spatial-resolution images, time-series images, light detection and ranging (LiDAR) data, etc. However, these data have not been fully utilized. To accurately identify the tree species of forest stands, various and complementary data need to be synthesized for classification. A curve matching based method called the fusion of spectral image and point data (FSP) algorithm was developed to fuse high-spatial-resolution images, time-series images, and LiDAR data for forest stand classification. In this method, the multispectral Sentinel-2 image and high-spatial-resolution aerial images were first fused. Then, the fused images were segmented to derive forest stands, which are the basic unit for classification. To extract features from forest stands, the gray histogram of each band was extracted from the aerial images. The average reflectance in each stand was calculated and stacked for the time-series images. The profile curve of forest structure was generated from the LiDAR data. Finally, the features of forest stands were compared with training samples using curve matching methods to derive the tree species. The developed method was tested in a forest farm to classify 11 tree species. The average accuracy of the FSP method for ten performances was between 0.900 and 0.913, and the maximum accuracy was 0.945. The experiments demonstrate that the FSP method is more accurate and stable than traditional machine learning classification methods.

We present the observations of two type III solar radio events performed with LOFAR (LOw-Frequency ARray) station in Bałdy (PL612), Poland in single mode. The first event occurred on 20th August 2017 and the second one on 9th September 2017. Solar dynamic spectra were recorded in the 10 MHz up to 90 MHz frequency band. Together with the wide frequency bandwidth LOFAR telescope (with single station used) provides also high frequency and high sensitivity observations. Additionally to LOFAR observations, the data recorded by instruments on boards of the Interface Region Imaging Spectrograph (IRIS) and Solar Dynamics Observatory (SDO) in the UV spectral range complement observations in the radio field. Unfortunately, only the radio event from 9th September 2017 was observed by both satellites. Our study shows that the LOFAR single station observations, in combination with observations at other wavelengths can be very useful for better understanding of the environment in which the type III radio events occur.

Published: January 2021

Clouds act as a major reflector that changes the amount of sunlight reflected to space. Change in radiance intensity due to the presence of clouds interrupts the retrieval of trace gas or aerosol properties from satellite data. In this paper, we developed a fast and robust algorithm, named the fast cloud retrieval algorithm, using a triplet of wavelengths (469, 477, and 485 nm) of the O2–O2 absorption band around 477 nm (CLDTO4) to derive the cloud information such as cloud top pressure (CTP) and cloud fraction (CF) for the Geostationary Environment Monitoring Spectrometer (GEMS). The novel algorithm is based on the fact that the difference in the optical path through which light passes with regard to the altitude of clouds causes a change in radiance due to the absorption of O2–O2 at the three selected wavelengths. To reduce the time required for algorithm calculations, the look-up table (LUT) method was applied. The LUT was pre-constructed for various conditions of geometry using Vectorized Linearized Discrete Ordinate Radiative Transfer (VLIDORT) to consider the polarization of the scattered light. The GEMS was launched in February 2020, but the observed data of GEMS have not yet been widely released. To evaluate the performance of the algorithm, the retrieved CTP and CF using observational data from the Global Ozone Monitoring Experiment-2 (GOME-2), which cover the spectral range of GEMS, were compared with the results of the Fast Retrieval Scheme for Clouds from the Oxygen A band (FRESCO) algorithm, which is based on the O2 A-band. There was good agreement between the results, despite small discrepancies for low clouds.
A Synthetic Quantitative Precipitation Estimation by Integrating S- and C-Band Dual-Polarization Radars over Northern Taiwan
Authors: Chen Ju-Yu , Chang Wei-Yu , Chang Pao-Liang
Published: January 2021

The key factors, namely, the radar data quality, raindrop size distribution (RSD) variability, and the data integration method, which significantly affect radar-based quantitative precipitation estimation (QPE) are investigated using the RCWF (S-band) and NCU C-POL (C-band) dual-polarization radars in northern Taiwan. The radar data quality control (QC) procedures, including the corrections of attenuation, the systematic bias, and the wet-radome effect, have large impact on the QPE accuracy. With the proper QC procedures, the values of normalized root mean square error (NRMSE) decrease about 10~40% for R(ZHH) and about 5~15% for R(KDP). The QPE error from the RSD variability is mitigated by applying seasonal coefficients derived from eight-year disdrometer data. Instead of using discrete QPEs (D-QPE) from one radar, the synthetic QPEs are derived via discretely combined QPEs (DC-QPE) from S- and C-band radars. The improvements in DC-QPE compared to D-QPE are about 1.5–7.0% and 3.5–8.5% in R(KDP) and R(KDP, ZDR), respectively. A novel algorithm, Lagrangian-evolution adjustment (LEA), is proposed to compensate D-QPE from a single radar. The LEA-QPE shows 1–4% improvements in R(KDP, ZDR) at the C-band radar, which has a larger scanning temporal gap (up to 10 min). The synthetic LEA-QPEs by combining two radars have outperformed both D-QPEs and DC-QPEs.
Exploring the Impact of Climate and Extreme Weather on Fatal Traffic Accidents
Authors: Zou Yajie , Zhang Yue , Cheng Kai
Published: January 2021

Climate change and the extreme weather have a negative impact on road traffic safety, resulting in severe road traffic accidents. In this study, a negative binomial model and a log-change model are proposed to analyse the impact of various factors on fatal traffic accidents. The dataset used in this study includes the fatal traffic accident frequency, social development indicators and climate indicators in California and Arizona. The results show that both models can provide accurate fitting results. Climate variables (i.e., average temperature and standard precipitation 24) can significantly affect the frequency of fatal traffic accidents. Non-climate variables (i.e., beer consumption, rural Vehicle miles travelled ratio, and vehicle performance) also have a significant impact. The modelling results can provide decision-making guidelines for the transportation management agencies to improve road traffic safety.
Evaluating Different Catch Crop Strategies for Closing the Nitrogen Cycle in Cropping Systems—Field Experiments and Modelling

Published: January 2021

For arable stockless farming systems, the integration of catch crops (CC) during the fallow period might be a key for closing the nitrogen (N) cycle, reducing N leaching and increasing the transfer of N to the subsequent crop. However, despite considerable research efforts, the fate of N in such integrated systems remains unclear. To address this, a two-year field experiment was carried out in northern Germany with different CC, including frost-tolerant and frost-killed CC. The experiment started following a two-year ryegrass/red clover ley, which was subsequently sown with a cereal (CE) or a grain legume (field pea, PE). This provided two contrasting systems with high residual N in autumn. The results showed high N uptake of the CC, ranging from 84 to 136 kg N ha−1 with PE as the pre-crop, and from 33 to 110 kg N ha−1 with CE. All CC reduced N leaching compared with the control, a bare fallow over autumn/winter. Of the various CC, the frost-killed CC showed higher leaching compared with the other CCs, indicating mineralisation of the CC residue in the later autumn/winter period. The process based APSIM (Agricultural Production SIMulator) model was used to simulate N cycling for a cereal grain legume rotation, including a frost-killed and a frost resistant CC. While the model simulated the biomass and the N uptake by the crops, as well as the reduction of N leaching with the use of CC well, it under-estimated N leaching from the frost-killed CC. The study showed that all CC were affective at reducing N leaching, but winter hard catch crops should be preferred, as there is a risk of increased leaching following the mineralisation of residues from frost-killed CC.

Published: January 2021

Knowledge of the characteristics of speed at roundabouts is very important in design procedures, simulation models, and determining the influence of these roundabouts on traffic conditions in a street network. Sustainable management in the street network means the influence of all its parts on traffic conditions and travel time. In order to reliably determine roundabouts parameters in the procedures of planning and the choice of sustainable method of traffic management, it is very important to know the values of the traffic flow parameters, particularly the speeds at the entry and exit leg, as well as in the circulatory zone. This article analyses the speed characteristics in traffic flow at urban roundabouts with different geometrical characteristics in the city of Banja Luka. The applied method for traffic data collecting in this research was the method of video recording processing, which excludes any influence on driver behavior. Furthermore, statistical analysis was conducted, which established the correlation between the achieved speeds and geometrical characteristics of the intersection. Due to roundabout characteristics, the research was focused on the access, that is, the entry leg, the segment of the circulatory zone and the exit leg. The research results showed there is a significant dependence between geometrical characteristics of certain elements of the roundabout on speeds. In the further course of the research, it was proved that the variation of speeds at the segments of roundabouts significantly affects the size of time losses and emission of pollutants, i.e., parameters based on which it is possible to objectively assess the possibility of sustainable implementation of the planned solution of roundabouts of similar geometry within the street network in cities similar to Banja Luka.

Published: January 2021

Instant Messaging is widely used in people’s daily life because of its convenience and timeliness. People have to deal with this communication almost every day. At present, most of the researches focuses on the instant messages of the receiver, but rarely explores the perspective of the sender. Based on the conservation of resources theory, we propose a model that initiates communication indirectly affects one’s own follow-up helping behavior. The results showed that (a) Instant Message sent has a positive correlation with perceived work goal progress; (b) Perceived work goal progress mediates the relationship of Instant Message sent and helping; (c) The mediating effect of perceived work goal progress on the relationship between Instant Message sent and helping will be moderated by the usefulness of reply. Our study builds a framework to explain how sent instant messages can increase helping via perceived goal progress, broaden the knowledge of Instant Messaging and helping. The practical implications are further discussed.
Exploring the Emergence of Innovative Multi-Actor Collaborations toward a Progressive Urban Regime in Madrid (2015–2019)
Authors: Medina-García Clara , de la Fuente Rosa , Van den Broeck Pieter
Published: January 2021

For the last decade, urban actors around the globe have been struggling to adapt to a post-crisis and austerity context through increasing social mobilization and experimentation, calling for an urban democracy renewal and challenging established neoliberal urban regimes and governance systems. This has triggered social innovations, in which novel collaborative formulas have been envisioned and implemented. In particular, civil-public collaborations (CPCs) have come to the fore as an empowering alternative to the well-established private–public partnerships (PPP). This article examines the conditions of possibility, enabling mechanisms and constraints for the emergence of innovative multi-actor collaborations (IMACs). For this aim, we developed a three-fold analytical framework combining social innovation, public governance, and urban regime theory. We applied this framework to the case of the so-called “government of change” in Madrid between 2015 and 2019. After exploring the pre-2015 context, the institutional innovations implemented once Ahora Madrid accessed the local government, and the post-2019 context, it points to the preconditions that allowed experimentation with IMAC, identifies the institutional mechanisms and governance innovations that support their emergence, and assesses to what extent and how power to act was created and used to accomplish urban regime change.
The Role of Social Networks in Mobile Phone Use among Pedestrians: A Pilot Study in China
Authors: Hou Mingyu , Cheng Jianchuan
Published: January 2021

Pedestrian safety is alarming worldwide, and it is well validated that distracted walking/crossing involving mobile phone use would significantly compromise pedestrian safety. Some existing studies demonstrated that distracted pedestrians would spend more time to cross street, miss more safe opportunities to cross and pay less attention to the road environment, etc. As a result, they are more likely to be hit by an oncoming vehicle. Specifically, with respect to the distraction results from mobile phone use for communication in road user groups, previous research has examined the relationship between social networks and mobile phone use among drivers and motorcyclists. However, very little similar research was found in the field of pedestrian study. This study performed an online survey to investigate with whom pedestrians were most likely to communicate with while crossing street in a Chinese sample. The association between social networks and self-reported injury/ near miss event was also examined. To provide an insight into the difference in communication pattern between scenarios, the results were compared with the patterns while driving, motorcycling and the general patterns. Results indicate that pedestrians are most likely to communicate with friends (31.2%), followed by spouses (24.5%). Additionally, participants who frequently talk to parents/children have a greater likelihood of being involved in injury/ near miss events than those talk to the others. Compared with the prevalence of mobile phone use among drivers and motorcyclists reported in previous studies, mobile phone use is more prevalent among pedestrians, especially as they are more likely to communicate with colleagues. In sum, the results demonstrate that social networks play an important role in mobile phone use during street crossing, and pedestrians are more likely to communicate with people who are socially closest to them. The effect of social networks on mobile phone use (especially for communication) among pedestrians should be considered in the development of traffic safety countermeasures.

Published: January 2021

There are still concerns about masseteric bulging due to a lack of knowledge about the internal architecture of the masseter muscle. Further investigations are therefore required of the most-effective botulinum neurotoxin (BoNT) injection points and strategies for managing masseteric bulging. The purpose of this study was to identify safer and more effective botulinum neurotoxin injection points and strategies by using ultrasonography to determine the structural patterns of the deep inferior tendon. We also measured the precise depths and locations of the deep inferior tendon of the masseter muscle. Thirty-two healthy volunteers participated in this study, and ultrasonography was used to scan the masseter muscle both longitudinally and transversely. Three structural patterns of the deep inferior tendon were identified: in type A, the deep inferior tendon covered the anterior two-thirds of the masseter muscle (21.8%); in type B, the deep inferior tendon covered the posterior two-thirds of the masseter muscle (9.4%); and in type C, the deep inferior tendon covered most of the inferior part of the masseter muscle (68.8%). Depending on the ultrasonography scanning site, the depth from the skin surface to the mandible in the masseteric region ranged from 15 to 25 mm. The deep inferior tendon was typically located 2 to 5 mm deep from the mandible. Ultrasonography can be used to observe the internal structure of the masseter muscle including the deep inferior tendon in individual patients. This will help to reduce the side effects of masseteric bulging when applying retrograde or dual-plane injection methods depending on the structural pattern of the deep inferior tendon.

La mémoire des attentats de 2015 : une collecte atypique des Archives municipales de Rennes
Authors: Penlaë Marie
Published: January 2021

Après les attentats de janvier et novembre 2015, des mémoriaux éphémères constitués de messages et d’objets ont été érigés à Rennes, place de la Mairie. En dépit de l’intérêt de ces témoignages, le contexte politique délicat rendait l’initiative de les collecter ni évidente ni aisée. Une fois la collecte confiée aux Archives municipales de Rennes, celles-ci ont mis en oeuvre le tri et les mesures de conservation qui s’imposaient. Le contenu de ce corpus documentaire peut être éclairé par le contexte de production grâce à deux éléments. Le premier est l’enquête effectuée par l’archiviste auprès des producteurs, dont le questionnement peut s’appliquer à ce corpus documentaire pourtant constitué dans des conditions peu courantes au regard des fonds habituellement collectés. Le second élément est la dimension spatiale, qui apparaît comme un élément de contexte documentaire à part entière.

La médiation aux archives : pour une complémentarité des compétences.

Entre la médiation-facilitation dans un service d’archives, propre à la communication des archives par son personnel, et la médiation-valorisation, compétence spécifique d’un personnel dédié, souvent sans compétence archivistique, y a-t-il opposition ou complémentarité ? Le Rize, équipement culturel polyvalent de Villeurbanne qui englobe les archives de la ville, tente de faire coexister ces missions, en diversifiant des actions qui répondent ou suscitent la demande de publics différents. La complémentarité entre médiateur et archiviste est particulièrement manifeste dans une initiative originale : Les «Mots parleurs » , atelier d’écriture à partir d’un document d’archives. Les actions menées à Villeurbanne concernent autant les adultes avec, par exemple, ces «Mots parleurs » , «Les archives racontent » , l’inventaire architectural participatif, ou encore l’encyclopédie en ligne, que les plus jeunes, avec des mallettes pédagogiques, ateliers utilisant Minecraft et plans archivés ou atelier «Archive ta classe ». Pour toutes ces animations, allier les compétences s’avère indispensable pour enrichir l’offre culturelle de l’équipement.

Politique archivistique et évolutions territoriales : les années décisives 2010-2018

Depuis 2010, de nombreuses mesures législatives ont affecté l’organisation territoriale de la France, accélérant en particulier au niveau local, dans un certain nombre de départements, des mouvements de regroupements communaux sous la forme de «communes nouvelles » . Cette évolution a été particulièrement rapide et forte dans le département de Maine-et-Loire, qui comptait en 2010 363 communes, et n’en compte plus, à la fin de l’année 2018, que 180. Parallèlement l’on assistait à une forte structuration des EPCI, structurés en neuf entités par le schéma départemental de coopération intercommunal publié par le préfet le 28 février 2016. Face à cette nouvelle réalité, le mode original d’intervention des Archives départementales à l’égard des communes et de leurs groupements mis au point depuis une vingtaine d’années, fait la preuve de son efficacité et de sa capacité d’adaptation. Une équipe d’une douzaine d’archivistes, coordonnés par le service départemental lui-même, sillonne le territoire et accomplit, tant auprès des nouvelles entités que des anciennes, des missions de classement et d’organisation qui s’étendent désormais aussi au contexte électronique. Le succès est au rendez-vous, mais l’importance de la demande et sa diversité représente un défi permanent.

Comparison of Three Different Learning Methods of Multilayer Perceptron Neural Network for Wind Speed Forecasting
Authors: BULUT Mehmet , TORA Hakan , BUAISHA Magdi
Published: January 2021

In the world, electric power is the highest need for high prosperity and comfortable living standards. The security of energy supply is an essential concept in national energy management. Therefore, ensuring the security of electricity supply requires accurate estimates of electricity demand. The share of electricity generation from renewables is significantly growing in the world. This kind of energy types are dependent on weather conditions as the wind and solar energies. There are two vital requirements to locate and measure specific systems to utilize wind power: modelling and forecasting of the wind velocity. To this end, using only 4 years of measured meteorological data, the present research attempts to estimate the related speed of wind within the Libyan Mediterranean coast with the help of ANN (artificial neural networking) with three different learning algorithms, which are Levenberg-Marquardt, Bayesian Regularization and Scaled Conjugate Gradient. Conclusions reached in this study show that wind speed can be estimated within acceptable limits using a limited set of meteorological data. In the results obtained, it was seen that the SCG algorithm gave better results in tests in this study with less data.

TERRITÓRIO, FRONTEIRA E CONECCIDADE: UM OLHAR PARA A FRONTEIRA FRANCO-BRASILEIRA
Authors: Moura Edenilson Dutra de
Published: January 2021

O presente artigo propõe a análise das dinâmicas territoriais reticulares na fronteira franco-brasileira e nas suas relações com a produção do espaço fronteiriço, destacando a centralidade que a fronteira representa nas relações socioespaciais estabelecidas na cidade de Oiapoque, localizada no estado do Amapá e que faz fronteira com a Guiana Francesa. Dessa forma, os conceitos de fronteira, território e rede foram selecionados pela capacidade que representam para compreender e alicerçar as relações de poder na delimitação em escalas analíticas maiores, configurando os territórios-rede fronteiriços. No tocante aos procedimentos metodológicos, destacamos, além dos levantamentos teórico-conceituais e uma abordagem qualitativa, a importância das observações e experiências in loco realizadas entre os anos 2016 e 2018. Na fronteira franco-brasileira na contemporaneidade, observamos novos arranjos territoriais, como exemplo deste processo, temos a abertura parcial da Ponte Binacional, que possibilita novas articulações dos territórios-rede que reorganizam a dinâmica regional e dinamizam o papel de diferentes protagonistas que atuam no processo de conexidade na fronteira, como os catraieiros e os pirateiros. Os novos arranjos territoriais tendem a transformar os diferentes fluxos sob a lógica reticular e, assim, estabelecem novas formas de produção do espaço urbano-fronteiriço. Destacamos que a complexidade e a análise dos territórios-rede permitem trazer a fronteira como centralidade da discussão territorial e não a tem enquanto uma temática marginalizada, com isso, essa abordagem coloca-se como estratégica para o entendimento das redes que são estabelecidas territorialmente, revelando o seu potencial de análise no desvelar fronteiriço.
PENGARUH WAKTU PENJEPITAN TALI PUSAT TERHADAP KADAR HEMOGLOBIN DAN BILIRUBIN BAYI BARU LAHIR
Authors: Syamsuddin Sri Devi , Jayanti Ira
Published: January 2021

Latar belakang : Masa setelah bayi lahir, terjadilah peralihan peran oksigenasi dari plasenta ke paru bayi. Selama masa tersebut, oksigenasi bayi melalui plasenta masih berlanjut. Jika peran oksigenasi plasenta dihentikan mendadak (penjepitan dini), sementara paru belum berfungsi optimal, maka cerebral blood flow menjadi tidak adekuat.

Tujuan : untuk membuktikan lebih lanjut dari penelitian sebelumnya yaitu adanya pengaruh waktu penjepitan tali pusat setelah bayi lahir terhadap kadar hemoglobin (Hb) dan Bilirubin bayi.

Metode : cross sectional, menganalisis pengaruh waktu penjepitan tali pusat ≥ 2 menit (penjepitan tunda) setelah bayi lahir terhadap kadar Hb dan Bilirubin bayi dibandingkan dengan < 2 menit (penjepitan segera). Tahapan pertama (1) pemantauan persalinan dan intervensi penundaan pemotongan tali pusat, (2) perbandingan dilakukan pemotongan tali pusat segera, (3) pengambilan sampel darah bayi baru lahir melalui arteri brachialis. Kedua, analisis darah bayi di laboratorium tingkat keakuratan 99,99%.

Hasil : uji regresi linier, menunjukkan pengaruh waktu penjepitan tali pusat dengan kadar Hb dan bilirubin bayi menunjukkan pengaruh yang kuat (r=0,905).

Simpulan : ada pengaruh waktu penjepitan tali pusat terhadap kadar Hemoglobin bayi tetapi tidak untuk kadar bilirubin bayi baru lahir.

Kata Kunci : Waktu penjepitan tali pusat, Hemoglobin, bilirubin, bayi baru lahir.

Tema perkalian dan pembagian pecahan pada pembelajaran matematika masih menjadi hal yang sulit bagi peserta didik di kelas IV SDN 3 Batu Kumbung. Hal ini dibuktikan dengan rendahnya capaian hasil belajar kognitif  peserta didik pada tema perkalian dan pembagian pecahan yang rata-rata dibawah KKM. Oleh karena itu, penelitian ini bertujuan untuk meningkatkan hasil belajar kognitif melalui variasi model pembelajaran dengan model pembelajaran kooperatif tipe Numbered Head Together (NHT) pada tema perkalian dan pembagian pecahan. Penelitian ini merupakan penelitian tindakan kelas yang dilakukan pada peserta didik kelas IV SDN 3 Batu Kumbung yang berjumlah 21 orang dengan dua siklus. Data diperoleh dengan teknik tes dan dianalisis melalui statistik deskriptif. Hasil penelitian menunjukkan bahwa dari siklus pertama hanya terdapat sedikit peningkatan, namun setelah para peserta didik kelas IV diberikan petunjuk dan penguatan, hasil belajar kognitif pada tema perkalian dan pembagian pecahan meningkat melebihi nilai KKM. Siklus dihentikan setelah nilai rata-rata hasil belajar kognitif pada tema perkalian dan pembagian pecahan telah tercapai atau melebihi nilai kriteria ketuntasan minimal.

Authoritarianism and Judicial Efforts for Securing Autonomy: A Case Study of Pakistan
Authors: Munir Dr. Bakht , Khan Ali Nawaz , Cheema Zaheer Iqbal
Published: January 2021

In a democratic system of government, state affairs are divided into legislative, executive, and judiciary. In Pakistan’s democratic transition, military role as an additional unavoidable stakeholder cannot be neglected. Pakistan remained under despotic regime for more than three decades with judicial backing by validating extraconstitutional acts. However, this autocratic rule never remained absolute and unchallenged. With qualitative research methodology this article examined how judiciary validated extraconstitutional acts at the expense of civilian governments and compromised its autonomy. How military role in democratic transition is minimized through parliamentary and judicial efforts. The research at hand aimed to investigate how military and its affiliates entrenched its authority during its direct rule and how it transformed and preserved that authority during civilian rule. How judiciary challenged and circumscribed unbridled military rule while securing its autonomy. This paper also explicated potential risk of confrontation between parliament and judiciary where the latter remained absolute autonomous. In order to overcome prospects of potential confrontation, this research suggested judicial realization of self-restraints so as to avoid unnecessary intrusion that could result into interbranch conflicts.

The Standard Output of Forest Index ‒ an Indicator of Site Quality
Authors: Schiberna Endre
Published: January 2021

The Standard Output of Forest Index (SOFI) describes the ability of forests to produce financial value from wood production based on the standardized monetary value of the mean annual increment of the potential final harvest relative to a reference forest type. It can be applied on regions where the forests can be classified into major tree species or species groups and into site classes. The potential volume of final wood harvest is estimated through yield tables. Using the share of lowquality and high-quality wood product groups in the final harvest, and their respective standardized price, the output value of the final harvest is expressed and then divided by the rotation age. This standardized output is compared to a reference forest type identified by its tree species and site class, and multiplied by 10 points. The SOFI of the reference forest, therefore, is 10, while higher values represent higher potential output and smaller values represent smaller potential output. With the necessary modifications, the SOFI can be applied to uneven-age forests as well. It can primarily be used to describe and compare the financial output potential of larger forest areas.
