Malaysian Electoral System Reform and the Challenges of its Implementation After the 14th General Election
Authors: Mat Ali Mohamad Fairuz , Yusoff Mohammad Agus
Published: January 2022

Prior to the 14th general election (GE-14), electoral practices in Malaysia have been often criticised as being obscure and biased since it was plagued with issues such as dubious voter registers and ballot paper fraud. Therefore, in its manifesto during GE-14, Pakatan Harapan (PH) promised to reform this electoral practice to make it more independent, transparent, and fair. PH then won the GE-14 on the strength of this vow, forcing it to keep its manifesto pledge. However, implementing the said promise is not easy as most of the proposals involve amendments to the Federal Constitution that require the support of at least a two-thirds majority. The fact that PH lacks such a majority has raised the issue of whether or not the objective to reform the electoral system can be materialised. Thus, this article examines the aspects of electoral reform implemented by PH during its 22 months in power and assesses the challenges faced in implementing such electoral system reform. The concept of electoral reform was used as an analytical tool in this article. This article mainly obtained its data from secondary sources including books, journals, theses, official government documents and websites, while primary data were collected from unstructured interviews with authoritative informants. Findings revealed that among the important reforms of the country's electoral system that have been accomplished by PH are improving the standard operating procedures of elections, enhancing election rules that do not require amendments, amending laws that require simple majority support in the parliament, and implementing ‘high-impact’ electoral reforms that require amendments to the Federal Constitution. Moreover, it was also discovered that the main challenge to reforming the electoral system was the constraint of electoral rule amendments that require the approval of a two-thirds majority of parliamentarians. Other obstacles included politicians' unwillingness to accept a new electoral system culture, barriers to accessing data and information owned by other agencies, discrepancies between federal and state legislation, and financial constraints on improving existing hardware and systems necessary for electoral reform success.

Introduction. Wearing a face mask is an important measure against spread of infection during the COVID-19 pandemic. The purpose of the study was to analyze various aspects of the face masks use by the population during the pandemic. The questioner was used. Results. Almost all respondents (96.4%) wore respiratory protective devices during the pandemic; 91.4% respondents worn face masks visiting grocery stores, pharmacies and medical organizations; 64.0% - visiting non-food trade facilities; 76.9% - travelling by surface transport, and 76.1% - being on the subway. Different types of face masks were used, 93.3% of respondents used disposable medical mask, 25.4% - reusable cloth masks. However, only 44.8% of respondents indicated that their protective equipment was made of non-woven material; 26.1% did not know how many layers their protective equipment contained; about a third of respondents (20.1% - 30.21%) were not able to assess the effectiveness of different types of respiratory protection. A third of the respondents (33.6%) wore a disposable medical mask for 2 hours, 35.2% - more than 2 hours in one day, 28.0% - for several days. Conclusions. Most of the respondents wore the face mask. Disposable medical masks were most commonly used. Requirements for the duration of wearing of face masks were met by about third of the respondents, for the handling - half of the respondents. Spontaneous choice of face mask by respondents confirms the importance of the development of hygiene guideline for choosing the most effective respiratory protection.
Az AUKUS megállapodás francia szempontból
Authors: Fejérdy Gergely
Published: January 2022

A 2021. szeptember 15-én megalakult AUKUS szövetség, jelentős fordulatot hozott az indopacifikus térségben. A tanulmányban arra teszünk kísérletet, hogy a különösen is érintett Franciaország szempontjából vizsgáljuk ezt az eseményt. A 2016-ban megkötött ausztrál– francia védelmi megállapodás és az ehhez kapcsolódó tengeralattjáró-export egyoldalú megszüntetése váratlanul érte Párizst, jóllehet több előjel már arra mutatott, hogy a geopolitikai helyzet megváltozása Canberrát alternatív megoldásokra kényszeríti. Az ausztrál döntéshez vezető okok vizsgálatán – amelyek között Új-Kaledónia függetlenségi törekvése sem utolsó szempont – a francia reakciók, szempontok feltérképezésén túl az elemzés arra keres választ, hogy milyen következményekkel jár ez az esemény Franciaország számára. A térség országai közül felértékelődhetnek a kapcsolatok többek között Indiával, Japánnal, Dél-Koreával, Indonéziával stb., és az európai partnerek fokozottabb bevonására is sor kerülhet ahhoz, hogy Párizs az általa kívánt ún. „harmadik utas politikát” meg tudja valósítani a térségben. A francia (és egyben európai) érdek a dialógus felerősítése és a nézeteltérések gyors rendezése, mert Kína a nyugati szövetségi rendszeren kialakuló minden repedést könnyedén kihasználhat kizárólag a saját javára.

DESISTANCE AND VICTIM PROTECTION IN ROMANIA: COLLABORATION BETWEEN PROBATION AND PRISON FROM THE PERSPECTIVE OF THE PROGRAMME ‘REDUCING THE RISK OF RELAPSE’
Authors: SANDU MARIA
Published: January 2022

Criminologically, the psychosocial and educational perspectives on the person who commits acts of aggressiveness, including sexual abuse, are based on several theoretical models of intervention, which are included in the bio-pathological, psychological and sociocultural perspectives. This is the very premise of the assisted desistance as a succession of stages developed within the criminal trial, and taking risk management as the fundamental principle applied in the custodial and probation system. Firstly, this article starts from a case study conducted in the Romanian probation system, which is presented at the “Fifth International Conference Multidisciplinary Perspectives in the Quasi-Coercive Treatment of Offenders. Probation as a field of study and research: From person to society” (2016). Secondly, it reflects the collaboration between prison and probation in the primary and secondary desistance using the programme ‘Reducing the Risk of Relapse’ (RRR) after prison, which uses the complementary ‘risk, needs and responsivity’ (RNR) model with the “Good Life Model” (GLM) based on combining the principle of individual responsiveness with that of social responsibility. Our arguments are – in the sense of highlighting the importance of individualizing the sanction – focusing on the contextualized narrative identity, from secondary desistance to ensure the continuity of the post-sentence rehabilitation and the protection of the crime victim.
SOLUTION-FOCUSED APPROACH IN PREPARING INMATES FOR SOCIAL REINTEGRATION
Authors: POLEDNA SORINA
Published: January 2022

Focusing on solution is an alternative perspective of communication, professional activities and relationship in relation to the problem-solving approach, used in social work. Looking to the future, rather than the past, the solution-focused approach affirms the right of clients to establish the desired results. It believes that change can take place in a relatively short period of time, especially when clients are empowered and motivated to use their resources and strengths to build solutions. Focusing on solution is part of the theoretical and methodological horizon, rooted in constructivism and social constructionism, which among other ideas specific to postmodernism, states that language, rather than just a medium for expressing ideas, really determines thinking, to the extent that truth is the product of language. This means that problems and solutions can be built through the communication that the social worker in the penitentiary has with inmates. Through communication, change can occur either as a difference in the way a person sees his world, or as a person doing something different, or both. This approach is also productive in communicating with the inamtes in order to identify relevant and motivating objectives and solutions for behavioral rehabilitation and social reintegration.
THE RELATIONSHIP BETWEEN TRUST IN MEDIA AND FAKE NEWS: A SOCIOLOGICAL APPROACH
Authors: GAVRILUȚĂ CRISTINA , BORTOȘ SERGIU
Published: January 2022

Although the existence of fake news can be found in the last decade, this subject succeeded to impose and gain coverage among the current research topics, becoming important through the harmful effects it can produce, but also through its continuous dynamics and evolution. Through this paper we aim to present some theoretical perspectives on the phenomenon of fake news, then we will aim to make the connection between fake news and trust in the media (in any of its type, mass-media or new media). Through the theoretical analysis we aim to develop some hypotheses and subjects which could lead to future research. Therefore, by the present analysis – which has as scope the exploration of the possible relations between the population’s trust in the media and fake news – we focus on developing a theoretical framework, so that possible results could enhance a better knowledge and combatting the negative effects of this phenomenon.
Geology and pyrite-polymetallic mineralization of the forecasted
Limonite deposit, Rassokhinsky ore cluster (Yenisei ridge)
Authors: Serdyuk Sergey , Makarov Vladimir , Kirilenko Valentina , Makarov Ilya , Muromtsev Egor , Shvedov Gennady
Published: January 2022

The development of Russia’s largest Gorevskoye leadzinc

deposit (Gorevsky GOK, Novoangarsky OK) will

depend on promising deposits of the Angara polymetallic

ore region, in particular, those of the Rassokhinsky

ore cluster. Based on the analysis of geological and geophysical

information of previous and current studies,

a major Limonite pyrite-polymetallic (massive sulfide)

deposit is forecasted within it. The main lithological

and stratigraphic criterion for the localization of ores is

determined by their confinement to high-carbon black

quartz-sericite schists of the upper subformation of the

Potoskuy suite of the Upper Riphean. In the top of this

pack, layered and massive pyrite-polymetallic ores, 70–

140 m thick, are localized. Based on PPA data, lead and

zinc content in core varies from fractions of a percent

to several percent, based on the ICP-AES method: 0,1–

3,7 % Pb, 0,1–6,4 % Zn, Pb : Zn ratio is 1 : (1–10).
Rare metal-polymetallic mineralization of Koshmansay ore field
(Eastern Uzbekistan)
Authors: Ezhkov Yuri , Rahimov Rahmon , Holiyorov Anvar , Toshmetov Ubaydullo
Published: January 2022

The Koshmansai ore field is located in the southern

part of the granitoid Chatkal batholith, in its apical ledge

and exocontact zones, in the Koshmansai river basin. The

host environment of the granitoids is Lower Carboniferous

carbonate rocks, which were primarily affected by

intensive skarnification. Sedimentary-metamorphic and

volcanics rocks and granitoids constitute the geological

structure of the skarn rare-metal-polymetallic Koshmansai

deposit.

In the distribution of ore-forming and associated elе-

ments in the mineral phases of skarn orebodies, their

morphogenetic type plays a certain role. Thus, in bimetasomatic

skarns, minerals accumulate more Cu, Zn,

Ni, Te, Tl, Ge. In infiltration skarns, these are Ag, Pb, Bi,

Cd, Sb, Co. Sulfide polymetallic mineralization in skarns

is associated with quartz and calcite.

The Koshmansai ore field has a distinct geochemical

zoning, which can be subdivided into the Koshmansai rare-

metal-polymetallic deposit at the upper levels of the

ore field and the Nizhnekoshmansai rare-metal-copper

ore occurrence at its lower levels. Nevertheless, orebodies

formation proceeded in a similar thermodynamic

environment, in the conditions of upper shielding at low

temperature gradients, which makes it possible to consider

the ore field as a single geochemical anomaly. The

vertical geochemical zoning of ore-forming element halos

determined by their concentration at the lower section

levels of the Koshmansai deposit skarn orebodies suggests

the expansion of its prospects in depth.
Geological structure and localization of mineralization
at the Moryanikho-Merkurikhinskoye ore field
Authors: Zaitseva Maria
Published: January 2022

The paper discusses the lithological and facial features

of the terrigenous-carbonate (biohermic) ore-bearing

geological formation of the Moryanikho-Merkurikhinskoye

ore field (Yenisei Ridge), which hosts stratiform

lead-zinc deposits in carbonate strata. Ore-hosting lithofacies

and their paleostructural position are characterized.

Based on the previous studies, as well as the author’s

own materials obtained as a result of field work, the

main favorable lithological, facial and structural factors

for hosting Moryanikhinsky-type stratiform lead-zinc

mineralization are defined: the presence of paleodepressions

within the shelf zone; development of carbonate

rocks – dolomites, stromatolite dolomites and limestones,

which are biohermic structures on the slopes of

paleo-uplifts; the presence of an admixture of tuffaceous

material in terrigenous rock varieties.

The influence of tectonic faults on the formation of

ore deposits and the morphology of ore bodies is indicated.

The main types of ores of the Moryanikho-

Merkurikhinsky ore field, as well as their mineral composition

are described. The paper discusses the main ore

types, as well as their mineral composition typical of the

Moryanikho-Merkurikhinskoye ore field. The largest and

well-studied lead and zinc stratiform Moryanikhinskoye

deposit and Merkurikhinskoye ore occurrence located

within the ore field are briefly characterized.

The Moryanikhinskoye deposit is a typical example

for searching for stratiform deposits of lead and zinc in

the carbonate strata of the Angara-Bolshepitskaya mineragenic

zone, which is of practical interest in developing

predictive prospecting models of deposits and improving

the efficiency of prospecting.
Gold and silver accessory minerals in ultramafites
of the Kyzyr-Burlyuksky ultramafic massif (Western Sayan)
Authors: Yurichev Alexey
Published: January 2022

The study focuses on gold and silver accessory minerals

(native silver, cuprous gold, luanheite (Ag3Hg),

unspecified mineral phase (Cu,Ag,Hg), first diagnosed

in dunites and apodunite serpentinites of the Kyzyr-Burlyuksky

ultramafic massif, which is part of the Kurtushibin

ophiolite belt of Western Sayan. The revealed

ore minerals are mainly observed in the form of single

hypidiomorphic, irregular microscopic precipitates (0.5–

3.0 μm) mainly inside magnetite, much less often in

grains of avaruite. Typomorphic and chemical features

of ore minerals, their natural setting in rock-forming

silicate matrix are characterized. Formation and concentration

of these accessory minerals is associated with

superimposed low-temperature transformation (hydration)

processes affecting original ultramafic rocks. At the

same time, the presence of luanheite and an unnamed

phase (Cu,Ag,Hg), along with the previously identified

potarite (PdHg), is probably evidence of low-temperature

conditions of mineral formation during the manifestation

of epigenetic processes of serpentinization (lowgrade

metamorphism) due to solutions enriched in mercury.

The source of such solutions could be gabbro intrusions

that penetrated later into the main ultramafic body.

Hence, this study construes the data acquisition technique in neuroscience studies using electroencephalogram and outlines the trend of revolution of this technique in aspects of its technology and databases by focusing on neuromarketing uses.
IMPLEMENTATION OF TRANSONIC AREA RULE AND SWEPT BACK DELTA WING DESIGN ON AN AIRCRAFT.
Authors: Singh S. Rajat , Dwivedi Y.D.
Published: January 2022

The transonic area rule was first implemented in the 1950s. It is an important concept related to the drag on an aircraft or other body in transonic and supersonic flight which states that two airplanes with the same longitudinal cross-sectional area distribution have the same wave drag, independent of how the area is distributed laterally. A swept back delta wing increases the critical Mach number of the wing and performs well at low speeds, as a result of unique swirling vortices that form on the upper surface of the wing. BOOM Supersonic plans to bring back Supersonic Commercial aircrafts by implementing these modifications in the famous Concorde. In this paper two aircraft designs inspired by Concorde and BOOM Overture are compared using ANSYS Fluent. These were designed in CATIA with changes in fuselage dimensions, wing configuration and engine configuration. The lift to drag ratio of both the designs are calculated and compared. Pressure contours, velocity vectors, vector pathlines, turbulence pathlines and pressure pathlines are also compared. The results show that the design with the implementation of transonic area rule and swept back delta wing has a better Lift to Drag ratio when compared to the design with a wide fuselage and a delta wing design.

Published: January 2022

In this project, we intend to design a Canard wing-based Unmanned Aerial Vehicle (UAV), which can carry a wide range of missions, providing capabilities to handle our challenges with sophisticated care. Canard-based UAV is the latest trend in aviation technology designed for the use case of providing better maneuverability, which in result gives the UAV new capabilities, such as increased time for data gathering, transferring, and autonomous behavior.

The basic disciplines like Aerodynamics, Engineering design, Flight dynamics, Propulsion, and Performance are carried out during the UAV designing process. The proposed methodology applied in this project is weight estimation, initial sizing, aerofoil and wing geometry, fuselage sizing, tail sizing, T/W ratio, aerodynamics, and performance analysis. The design of Canard Based UAV leads to a deeper understanding of the trade-off studies of the UAV and is demonstrated by optimizing for designed missions like surveillance. A drafted sketch is presented at the end of the design phase featuring the selected configurations of major components.
Strip Malls, City Trees, and Community Values
Authors: Wolf Kathleen
Published: January 2022

Strip malls (also known as mini-malls) are a common urban land use, historically promoted by U.S. zoning practices that concentrate retail and commercial development in a narrow band along arterials and major streets. More recently, communities are redeveloping mini-mall zones, expanding landscape plantings as biotechnology, and attempting to create a sense of place. This study assessed public response to urban forest and landscape options. Surveys depicted varied roadside, property-edge treatments. Residents of three major cities in the Pacific Northwest, U.S., were asked to indicate their preferences and perceptions concerning a four-concept framework: visual quality, retail perceptions, patronage behavior, and pricing for goods and services. Respondents preferred landscaped roadsides and report positive retail behavior such as willingness-to-pay 8.8% more for goods and services in well-landscaped malls. Roadside management guidelines are proposed based on the research results.
Soil Moisture and Aeration Beneath Pervious and Impervious Pavements
Authors: Morgenroth Justin , Buchan Graeme
Published: January 2022

Pervious paving has been increasingly installed in urban areas as a stormwater management strategy. Pervious pavements exhibit similar strength to impervious analogues, but are highly permeable to air and water. These functional characteristics have led to speculation that pervious paving, used instead of impervious paving, could benefit urban trees. Given that permeability to air and water will have a direct effect on the soil environment, this paper describes research that explores the effect of pervious pavement on underlying soil physical conditions. Results indicate that while soil moisture and aeration dynamics differ greatly beneath paved and unpaved surfaces, differences are usually insignificant between pervious and impervious paving. If urban trees do benefit from overlying pervious paving relative to impervious paving, it is probably not a consequence of soil moisture or aeration. The results challenge existing theories and contribute to the understanding of how pervious pavements affect the moisture and aeration dynamics of underlying soils.

The most aggressive woody alien species are tree of heaven (Ailanthus altissima), Oriental bittersweet (Celastrus orbiculatus), multiflora rose (Rosa multiflora), Russian olive (Elaeagnus angustifolia), autumn olive (E. umbellata), buckthorn (Rhamnus frangula), Japanese honeysuckle (Lonicera japonica), and porcelain berry (Ampelopsis brevipedunculata). Ailanthus altissima, Ampelopsis brevipedunculata, and Celastrus orbiculatus are the most aggressive of the aforementioned aliens. These and additional woody nonnative vascular species can be removed from small areas of a few square meters by cutting, herbicide treatment or hand-pulling. It may be impossible to control, much less eradicate these alien invasives from Jamaica Bay Wildlife Refuge. This article presents guidelines for a scientific and experimental approach to this problem.
Systemically Applied Insecticides for Treatment of Erythrina Gall Wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae)

Published: January 2022

The erythrina gall wasp (EGW), believed native to Africa, is a recently described species and now serious invasive pest of Erythrina (coral trees) in tropical and subtropical locales. Erythrina are favored ornamental and landscape trees, as well as native members of threatened ecosystems. The EGW is a tiny, highly mobile, highly invasive wasp that deforms (galls) host trees causing severe defoliation and tree death. The first detection of EGW in the United States was in O´ahu, Hawai´i in April 2005. It quickly spread through the Hawai`ian island chain (U.S.) killing ornamental and native Erythrina in as little as two years. At risk are endemic populations of Erythrina as well as ornamental landscape species in the same genus, the latter of which have already been killed and removed from O´ahu at a cost of more than USD $1 million. Because EGW are so small and spread so quickly, host injury is usually detected before adult wasps are observed, making prophylactic treatments less likely than therapeutic ones. This study evaluates two stem-injected insecticides, imidacloprid (IMAjet ®) and emamectin benzoate, delivered through Arborjet Tree I.V.® equipment, for their ability to affect E. sandwicensis (wiliwili) canopy demise under severe EGW exposure. IMA-jet, applied at a rate of 0.16 g AI/cm basal diameter (0.4 g AI/in. dia.), was the only effective treatment for maintaining canopy condition of wiliwili trees. Emamectin benzoate, applied at a rate of ~0.1 g AI/cm basal diameter (~0.25 g AI/in. dia.), was not effective in this application, although it was intermediate in effect between IMA-jet and untreated trees. The relatively high concentrations of imidacloprid in leaves, and its durability for at least 13 months in native wiliwili growing on a natural, dryland site, suggest that treatment applications against EGW can impact canopy recovery even under suboptimal site and tree conditions.

Thaumastocoris peregrinus, an Australian native, is a new and serious pest of urban eucalypts planted in Sydney and commercial centers of Australia. In recent years, it has spread to and attained pest status in South African Eucalyptus plantations and, more recently, has been discovered in Argentina and Uruguay. Mature Eucalyptus scoparia street trees, growing in a southern Sydney suburb, were microinjected with imidacloprid at three concentrations and monitored for three years. The abundance of T. peregrinus on treated eucalypts declined significantly compared to untreated trees over this time. Further, at the lowest concentration of chemical this insect was effectively controlled for two years. Imidacloprid (SilvaShield®; Bayer Environmental Science) has been registered in Australia for the control of T. peregrinus.
An Experimental Analysis of the Impact of Tree Shade on Electricity Consumption
Authors: Laband David , Sophocleus John
Published: January 2022

Trees cast shade on homes and buildings, lowering the inside temperatures and thus reducing the demand for power to cool these buildings during hot times of the year. The potential monetary savings may be sizable, especially for those who live in hot climates, because electricity usage for cooling residential and commercial structures in summer months is costly. A controlled experiment was conducted to quantify the impact of tree shade on electricity consumption devoted exclusively to cooling a structure. We examine electricity consumption used to run air conditioning units set at identical temperatures in two otherwise identical buildings, one set in full sun, the other in full shade during the summer months of 2008 in Beauregard, Alabama. The building in full sun required 2.6 times more electricity for cooling than the building in full shade. Our findings contribute to a growing body of research which demonstrates that owners of residential and commercial properties located in hot regions can reap sizable monetary savings from shade trees that serve as natural complements to their artificial air-conditioning.
City Trees and Municipal Wi-Fi Networks: Compatibility or Conflict?
Authors: Lacan Igor , McBride Joe
Published: January 2022

Conflict between city trees and infrastructure remains a problem in urban forestry. Municipal Wi-Fi, a citywide wireless computer network, may become a part of urban infrastructure, and because trees can diminish Wi-Fi signals, potential exists for conflict between urban trees and municipal Wi-Fi. This study examines attenuation of Wi-Fi signals in the City of Mountain View, California, U.S. by positioning a wireless-equipped computer so that trees obstructed the line-of-sight (LOS) between the computer and a Wi-Fi access point. Signal attenuation ranged from < 2 dB to 19 dB (mean: 5.6 dB), depending on the number and types of trees present. Although trees significantly attenuated signals, they did not diminish the average signal strength below -75 dBm (the minimum for a Wi-Fi connection) in any of the tests. A general linear model (r2 = 0.55) indicated that some tree characteristics (tree size, canopy depth, leaf type), but not others (number of trees in LOS, presence of leaves, leaf size, and shape) helped explain variation in signal attenuation. As long as the effect of urban trees is taken into account during planning of Wi-Fi networks, trees should not interfere with municipal Wi-Fi operation.
A Meta-analysis of Studies Published in Arboriculture & Urban Forestry Relating to Organic Materials and Impacts on Soil, Tree, and Environmental Properties
Authors: Scharenbroch Bryant
Published: January 2022

Organic materials are commonly used in urban landscapes to improve soil quality and tree health. Literature reviews suggest that the effects of organic materials are beneficial, but these impacts have yet to be evaluated using meta-analytical approach. This work presents a literature summary of 176 articles published in Arboriculture & Urban Forestry (AUF) and evaluates 33 of these papers using a meta-analysis. Research relevant to this topic is not published solely in AUF, but the meta-analysis is limited to AUF in an attempt to specifically focus on the information provided to AUF readers. This meta-analysis provides evidence of the mostly positive impacts organic materials have on shoot growth, root growth, tree physiology, and soil physical properties. It also identifies specific gaps in AUF literature for the effects organic materials have on soil chemical, soil biological, and environmental (e.g., climate, competition) properties. Further, this metaanalysis suggests the type of organic material and the mode of application have differential effects on tree, soil, and environmental properties.
Groundcovers, Organic and Inorganic Mulches, and Masonry Surfaces Differentially Affect Establishment and Root Zone Characteristics of Urban Trees
Authors: Arnold Michael , McDonald Garry
Published: January 2022

Three experiments investigated the effects of various groundcovers on establishment of redbuds [Cercis canadensis L. var. texensis (S. Watson) M. Hopkins ‘Alba’] and baldcypress [Taxodium distichum (L.) Rich.]. The first experiment involved eight surface treatments. Controls were bare soil. Remaining treatments were pine bark mulch; Asian jasmine [Trachelospermum asiaticum (Siebold & Zucc.) Nakai]; St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze]; decorative gravel; recycled paper mulch; decorative brick pavers; or seasonal rotations of herbaceous annuals. Other experiments compared brick-on-sand treatments ranging in color from light blonde to dark charcoal with bare soil on establishment of redbuds or baldcypress. Most organic and living soil surface covers were preferable to bare soils, however, some inorganic surface covers were detrimental to tree growth. Paving surfaces adversely affected survival, shoot or root growth, but differences were species dependent. Soil moisture, pH, and bulk density did not appear to be limiting under pavers, but substantial seasonal fluctuations in soil temperatures were observed. Light and medium bricks reflected more photosynthetically active radiation than dark bricks or bare soil. Atmospheric temperatures were greatest above dark and medium bricks. Root growth decreased as darkness of brick color increased. Redbud survival and growth were more adversely affected than with baldcypress
Paclobutrazol Foliar Sprays to Suppress Growth on Landscape Shrubs
Authors: Smiley E. Thomas , Holmes Liza , Fraedrich Bruce
Published: January 2022

This study was conducted to determine the effects of Paclobutrazol (PBZ, Cambistat) foliar sprays on the growth of four shrub species (Abelia × grandiflora ‘Edward Goucher’, Ligustrum japonicum ‘Rotundifolium’, Ligustrum sinense ‘Variegatum’, Loropetalum chinensis) in the southeastern United States. After the shrubs were established, they were sheared to a defined size and sprayed with 1000 ppm PBZ, 4000 ppm PBZ or left untreated. Paclobutrazol was effective at reducing growth on the four shrub species tested. Total biomass of new leaves and twigs collected 20 weeks after treatment was significantly less with PBZ treatment when compared to the nontreated control in all species except L. sinense. There were no differences in biomass that can be attributed to PBZ between the 1000 ppm and 4000 ppm treatments in any species tested. The speed of effectiveness and longevity of this treatment varied with species. In general, the faster growing the shrub species, the greater benefit and the faster the response from spray applications of PBZ. This growth reduction should provide a desirable appearance, less pruning and faster clean up when PBZ is applied to fast growing shrubs.
