history of Cuba. Many of them worked at a later time at the newly created Centro para la
9856_97
investigación y desarrollo de la música cubana (CIDMUC), founded in 1978.
9856_98
From this group we should mention two renowned musicologists that frequently worked in
9856_99
collaboration with each other: Victoria Elí (b. 1945) and Zoila Gómez (b. 1948). We should also
9856_100
mention Tamahra Martín (b. 1945), who dedicated two books to the Cuban choral music: “La música
9856_101
coral en Cuba” (1987) and “Música Coral” (1990).
9856_102
Two other important musicologists from this generation are: Alberto Alén Pérez (b. 1948) and
9856_103
Rolando Antonio Pérez Fernández (b. 1947). Alberto Alén applied his extensive knowledge of
9856_104
psychology and statistics to musical form analysis as well as music pedagogy, in publications such
9856_105
as: “La forma de las formas musicales” and “Diagnosticar la musicalidad”. Rolando Pérez developed
9856_106
extensive investigations about Afro-Cuban music and is well known for having documented and
9856_107
analyzed the process of transition from ternary rhythms to binary rhythms of the Cuban and Latin
9856_108
American popular music, during the 18th and 19th centuries, in his book: “Proceso de binarización
9856_109
de los ritmos ternarios africanos en América Latina (1987).”
9856_110
Olavo Alén (b. 1947) has closely followed the steps of Argeliers León in his studies of Afro-Cuban
9856_111
music and, most importantly, has elaborated and expanded León's theory of “generic complexes”, in
9856_112
works such as: “Géneros de la música cubana” from 1976.
9856_113
Those theories have been strongly refuted by other musicologists such as Leonardo Acosta, who
9856_114
explains in his article “De los complejos genéricos y otras cuestiones”:
9856_115
Other members of this Group are renowned musicologists Martha Ezquenazi (1949), Jesús Gómez Cairo
9856_116
(1949) and Dora Ileana Torres (1956).
9856_117
Most recently, a group of young Cuban musicologists have earned a well deserved reputation within
9856_118
the international academic field, due to their solid investigative work. Some of the most prominent
9856_119
members of this group are: Miriam Escudero Suástegui, Liliana González Moreno, Iván César Morales
9856_120
Flores and Pablo Alejandro Suárez Marrero.

The LAV III, originally named the Kodiak by the Canadian Army, is the third generation of the Light
9857_1
Armoured Vehicle (LAV) family of infantry fighting vehicles built by General Dynamics Land Systems
9857_2
– Canada (GDLS-C), a London, Ontario, based subsidiary of General Dynamics. It is a license-built
9857_3
version of the Mowag Piranha IIIH. It first entered service in 1999, succeeding the LAV II. It is
9857_4
the primary mechanized infantry vehicle of both the Canadian Army and the New Zealand Army. It also
9857_5
forms the basis of the Stryker vehicle used by the U.S. Army and other operators. The Canadian Army
9857_6
is upgrading its LAV IIIs to the LAV 6 standard.
9857_7
Development
9857_8
By July 1991, the Canadian Armed Forces had identified the need to replace their aging fleet of
9857_9
1960s and 1970s era armoured personnel carriers. As a result, $2.8 billion was earmarked for the
9857_10
Multi-Role Combat Vehicle (MRCV) project by the sitting Conservative government. The mandate of the
9857_11
MRCV project was to provide a series of vehicles based on a common chassis which would replace the
9857_12
M113 armored personnel carrier, Lynx reconnaissance vehicle, Grizzly armoured personnel carrier,
9857_13
and Bison armoured personnel carrier. The project was, however, deemed unaffordable and cancelled
9857_14
by March 1992.
9857_15
By 1994, after the Liberal Party had returned to government, the army was still in need of new
9857_16
vehicles. As a result, the army embarked on the Light Armoured Vehicle Project, which would adapt
9857_17
parts of the MRCV Project, and be implemented incrementally to spread out the costs. Also, the
9857_18
requirement to replace the Bisons was dropped. The first phase of the project saw the selection of
9857_19
the LAV II Coyote Reconnaissance Vehicle to replace the Lynx.
9857_20
General Motors Diesel proposed a license-built variant of the 8x8 Mowag Piranha IIIH incorporating
9857_21
the turret and weapon system of the Coyote. In August 1995, it was announced that GM Diesel (later
9857_22
renamed GM Defense, and subsequently purchased by General Dynamics Land Systems of London, Ontario)
9857_23
had been awarded the contract to produce the LAV III which would replace the Grizzly and a large
9857_24
portion of the M113 armoured personnel carriers.
9857_25
Future LAV 6
9857_26
In October 2011, GDLS-Canada was awarded a contract to upgrade 409 of the service's 651 LAV III
9857_27
APCs to the LAV 6 standard. Four variants were ordered: an infantry section carrier, a command
9857_28
post, an observation post and an engineer vehicle. The upgrade was expected to extend the service
9857_29
life of the vehicle to 2035. In February 2017, the service awarded GDLS-Canada a $404 million
9857_30
contract to upgrade 141 more LAV IIIs. In August 2019, GDLS-Canada received a four-year, $3 billion
9857_31
deal to build 360 armoured combat support vehicle variants. The first of these rolled off the
9857_32
assembly line in May 2021.
9857_33
Design Mobility
9857_34
The LAV III is powered by a Caterpillar 3126 diesel engine developing and can reach speeds above
9857_35
100 kilometres per hour. The vehicle is fitted with 8x8 drive and also equipped with a central tire
9857_36
inflation system, which allows it to adjust to different terrain, including off-road. The LAV III
9857_37
is fitted with a modern anti-locking brake system (ABS). Unlike earlier versions of the LAV, the
9857_38
LAV III does not have amphibious capabilities.
9857_39
The LAV III faces the same concerns that most other wheeled military vehicles face. Like all
9857_40
wheeled armoured vehicles, the LAV III's ground pressure is inherently higher than a tracked
9857_41
vehicle with a comparable weight. This is because tires will have less surface area in contact with
9857_42
the ground when compared to a tracked vehicle. Higher ground pressure results in an increased
9857_43
likelihood of sinking into soft terrain such as mud, snow and sand, leading to the vehicle becoming
9857_44
stuck. The lower ground pressure and improved traction offered by tracked vehicles also gives them
9857_45
an advantage over vehicles like the LAV III when it comes to managing slopes, trenches, and other
9857_46
obstacles.
9857_47
The LAV III can somewhat compensate for these effects by deflating its tires slightly, meaning that
9857_48
the surface area in contact with the ground increases, and the ground pressure is slightly lowered.
9857_49
However, wheels offer several advantages over tracked vehicles, including lower maintenance for
9857_50
both the vehicle and road infrastructure, quieter movement for improved stealth, greater speed over
9857_51
good terrain, and higher ground clearance. Wheeled vehicle crews are also more likely to survive
9857_52
mine or IED attacks than the crew of a similarly armoured tracked vehicle.
9857_53
The LAV III's turret gives the vehicle a higher centre of gravity than the vehicle was initially
9857_54
designed for. This has led to concerns that the vehicle is more likely to roll over on uneven
9857_55
terrain.
9857_56
While there have been several recorded rollovers (about 16), the most common cause was found to be
9857_57
unstable terrain, specifically road shoulders unexpectedly giving away beneath the vehicle. The
9857_58
weight balance of the LAV III is taken into consideration during driver training, largely
9857_59
mitigating the chances of a rollover.
9857_60
Protection
9857_61
The basic armour of the LAV III, covering the Standardization Agreement STANAG 4569 level III,
9857_62
which provides all-round protection against 7.62×51mm NATO small calibre rounds. A ceramic appliqué
9857_63
armour (MEXAS) can be added, which protects against 14.5×114mm heavy calibre rounds from 500
9857_64
meters. In December 2008 the Government of Canada awarded EODC Engineering, Developing and
9857_65
Licensing Inc. C$81.5 million worth of contracts to provide for add-on-armour kits, modules and
9857_66
spares for its LAV III wheeled armoured personnel carriers. This armour kit is intended to provide
9857_67
increased protection against improvised explosive devices (IED), explosively formed penetrators and
9857_68
30 mm caliber armour piercing rounds. The LAV III can be also fitted with cage armour, which
9857_69
provides protection against shaped charges. The LAV III is fitted with a nuclear, biological,
9857_70
chemical (NBC) filtration system accompanied with a GID-3 chemical detector and AN/VDR-2 radiation
9857_71
detector systems. The LAV III was designed to produce a very low and very compact structure to
9857_72
minimize radar and IR-signatures. The LAV III also uses heat-absorbing filters to provide temporary
9857_73
protection against thermal imaging (TIS), image intensifiers and infrared cameras (IR). General
