Abstract: Promising potentials
include farmers’ own farming systems research, alternatives to
questionnaire surveys, monitoring, evaluation and lateral spread
by local people, empowerment of the poorer and weaker, and
policy review. Changes in personal behavior and attitudes, and
in organizational cultures, are implied. PRA parallels and
resonates with paradigm shifts in the social and natural
sciences, business management, and development thinking,
supporting decentralization, local diversity, and personal
responsibility. Much of the spread of
participatory rural appraisal (PRA) as an emerging family of
approaches and methods has been lateral, South-South, through
experiential learning and changes in behavior, with different
local applications. Rapid spread has made quality assurance a
concern, with dangers from “instant fashion”, rushing, formalism
and ruts. Promising potentials include farmers’ own farming
systems research, alternatives to questionnaire surveys,
monitoring, evaluation and lateral spread by local people,
empowerment of the poorer and weaker, and policy review.

Abstract:
This article
will focus on the disadvantage of taking Online Classes. Online
education is not exactly a trend yet, but it is becoming
increasingly popular. The reason for this is that it offers new
opportunities where none existed before – Many people wouldn’t
have been able to acquire the necessary higher education without
it. However, like all things in life, taking Online Classes has
some drawbacks and disadvantages as compared to the traditional
classrooms. That said, online classes are not perfect for
everyone. To avoid getting caught in the hype and making the
wrong decision, consider the pros and cons of online education.
There are two types of programs offered by distance education
schools: synchronous learning programs and asynchronous learning
programs. With synchronous learning, distance education students
must log on to the school’s website at a set time. Often, they
interact with their peers and professors via group chats, web
seminars, video conferencing, and phone call-ins. With
asynchronous learning, distance education students complete all
coursework on their own time. They often learn via assignment
sheets, message boards, email, pre-recorded video lectures,
mp3s, and traditional mail correspondence.

Abstract:
Information and
communication technologies (ICT), including radio and television
and the newer digital technologies like computers and the
Internet as potentially are introduced powerful tools and
activators of educational reform and changes. different ICT,
when properly applied can be developed to help access to
education and the relationship between training and workshops to
strengthen the increasingly digital, the quality of education
also helped to create teaching and learning in an active process
connected to real life high take. However, the experience of
being raised by ICT in the classroom and other educational sites
around the world during the last few decades proves that is not
automatic fully realize the potential benefits of ICT training.
With the help of state and local funding, information technology
has been purchased for schools ever since the 1980s. The state
has also found many ways to support teacher training in the use
of IT, and it has also allocated funds for the production of IT
programs. Instruction in the use of IT has also played an
important role in teacher training organized by local school
authorities .It is against this background that the need arose
to find out how far we have progressed in the application of ICT
in education and what impacts these significant economic
investments have had. It is also time to start a value-oriented
discussion of how strongly the future of the Iran society—and
with it, of education and training— will be linked to the vision
of an information society brimming over with technology.

Aspects of
Decentralization in
rural

Abstract: Pubic extension
services are being forced to change. In the 1990s agricultural
extension services were attacked for being inefficient,
irrelevant, ineffective, and poorly targeted. The need for
reform was obvious and national systems responded with three
major strategies— privatization, decentralization, and program
revitalization. Although cost reduction has been the force
behind many changes, the principal objective of reforms should
be an attempt to improve quality of services to clients
Decentralizing extension services, when implemented effectively,
can transform extension and address a range of generic
problems. Decentralized extension brings decision making
processes closer to clients and makes programs more responsive
to user needs. Service providers become more accountable to
clients and better oversight increases efficiency of operations.
Decentralization itself can introduce a new dynamism in programs
and can promote diversity in service providers and program
approaches, thus serving as a first step toward privatization.
Agricultural extension is a non-formal type of education that
provides advisory services by the use of educational approach in
acquiring knowledge and skills to deal with the growing needs of
global world. Diverse agricultural extension funding and
delivery arrangements have been undertaken since the mid-1980s
by governments worldwide in the name of "privatization." When
agricultural extension is discussed, privatization is used in
the broadest sense – of introducing or increasing private sector
participation, which does not necessarily imply a transfer of
designated state-owned assets to the private sector. In fact,
various cost-recovery, commercialization, and other so-called
privatization alternatives have been adopted to improve
agricultural extension.

The role Rural women in rural
economic

Abstract:
As most men leave the village to work in town, women provide
much of the agriculture force in the area. In recent years the
situation has been more considerable as rural migration to town
is getting more. In most Iranian villages women’s population is
more than men. According to FAO’s reports, in some African
regions, for 60% of families, women are responsible for
supervising family. Even for cases that men are the direct
responsible of production affairs, women’s role in family
economy can’t be denied just because they don’t get paid.
Although these efforts appear to register in none of official
statistics, they easily replace some other activities with
significant financial value. Studies by FAO show that more than
half of the world’s crops are collected by women. According to
estimates, 1.3 billion of world’s poor are women, thus the
slogan “poverty has a feminine face” is spread worldwide. Given
that in many parts of the world, the production potential of
women is not used properly, a cost-benefit study by the World
Bank shows that investing on women in developing countries will
be more profitable than any other investment. In addition to
financial benefits of this huge force, its ancillary results
will also be useful. The ancillary benefits of women’s
employment include: lower population growth and children
mortality rates.

Abstract: Corncob residues are usually dumped and flared on the farms, where they
constitute health risk to both human and ecology. Densification
of corncobs would improve their bulk handling, transportation
and storage properties. This work investigated densification
characteristics of corncobs using an experimental briquetting
machine. Raw corncobs were milled into particles by a hammer
mill. The blends of ground corncob and cassava starch gel were
compacted in a 4-compartment briquetting machine, which operates
on hydraulic principle with a dwell time of 120 seconds. The ASAE standard methods were used to determine the moisture
contents (dry basis) and densities of the milled residues and
briquettes, while ASTM standard methods were used to determine
the proximate and ultimate analyses of the residues. The
compaction, density and relaxation ratios of the briquettes were
also determined. The mechanical properties were determined using
instron universal testing machine, while the heating value was
determined with the aid of Gallen Kamp Ballistic Bomb
calorimeter. The mean moisture content of the corncob
was 9.64 %, while the relaxed briquette was 7.46 %. The
corresponding value of bulk density of the residue material was
95.33 kg/m3. The initial, maximum and relaxed
densities of produced briquette were 193; 757 and 389 kg/m3
respectively, while the density, compaction and relaxation
ratios of the briquette were 0.77, 4.38 and 1.71 respectively.
The compressive strength of briquette was 2.34kN/m2,
while the higher heating value of briquettes was found to be
20,890kJ/kg. The study concluded that the densification and fuel
parameters were good enough and that briquettes produced from
corncob would make good biomass energy.

ABSTRACT:
The study was undertaken to study the self-concept and academic
achievement of normal and physically challenged secondary school
students of district Baramulla (J&K). The sample for the study
was 300 including150 normal secondary students selected randomly
and 150 physically challenged by using Purposive sampling
technique. Sager and Sharma’s self-concept inventory was
employed for the collection of data and t-test was employed for
the analysis of the data. The result of the study highlight that
the normal secondary school students have high academic
achievement and real self as compared to physically challenged
secondary school students. On the other hand, challenged were
found to have high ideal self as compared to normal students.

评陈蜀乔引力及量子真空图像
---- 21世纪新弦学概论(6)
朱科秋
摘要:陈蜀乔说他的理论和超弦/M理论都在朝统一四种力场的目标努力,但理论都未完善,且不可避免地要把这两种理论进行比对。其实,这两种理论只是分工不同:超弦/M理论是在往前冲,陈蜀乔的理论是在作超弦/M理论的回采。

盐亭大围坪盆塞海海啸遗迹地貌论
文绍文

Abstract:
海啸(tsunami)是一种巨大的海浪,主要是由海底地震、火山喷发、海岸崩塌、滑坡等海底地形大规模突变所引发的具有超长波长和周期的一种重力长波。海啸在大洋中的传播速度虽然很快(720~900公里/时),但浪高不大,通常为几十厘米至1米左右;而当其接近近岸浅水区时,波速变小,振幅陡涨,有时可达20~30米,骤然形成“水墙”,瞬时入侵沿岸陆地,造成极大危害。大部分海啸由深海地震引起。地震时造成海底发生激烈的上下方向的位移,从而导致其上方海水的巨大波动,海啸因此而发生。另外还有火山海啸和滑坡海啸。海啸引起海水从深海底部到海面的整体波动,蕴含的能量极大,因此有强烈的危害性,是一种严重的海洋灾害。海啸的形成条件是,海啸作为一种特殊的海洋浅水波,其形成需要如下三个主要条件:
震源较浅的大地震是先决条件。一般来说以倾滑为主(上下错动)、破裂过程持续长且震源深度较浅的海底大地震能引发海啸。第二是海啸源区的水深较大,多孕育于深海。如果地震释放的能量要变成巨大水体的波动能量,那么地震必须发生在深海,因为深海才有巨大的水体。发生在浅海的地震产生不了海啸,往往形成海洋激浪。第三是具有开阔并逐渐变浅的海岸条件。海啸要在陆地海岸带造成灾害,该海岸必须开阔,具备逐渐变浅的条件。海啸波在大洋中传播时,波高不到1米,不会造成灾害;但进入浅海后,因海水深度急剧变浅,前面的海水波减慢,后面的高速海水不停地前涌,从而造成波高急剧增加,形成巨大的破坏力。特别是,对于那些外侧宽广内侧狭窄的“三角型海湾”,越向海湾内侧,海啸的海浪越容易加剧升高,造成更大破坏。
