This document summarizes research on cultural variations in the nature and determinants of opinion leadership. The key findings are:
1) There are major differences between white and black farmers - differences between black cultures in different countries are smaller.
2) In black communities, physical accessibility is a major constraint, with 80% of opinion leaders living within 2km. Determinants normally associated with opinion leadership show negative relationships.
3) In white communities, socio-economic status is a barrier and socio-psychological accessibility is a major constraint, but not a factor in black communities. The document compares factors influencing opinion leadership across cultures.

Poverty Assessment in Urban Area of Jodhpur District in Western Arid Region o...IJAEMSJORNAL
An attempt has been made to assess the poverty status in rural area of Jodhpur district of western Rajasthan. Two villages were randomly selected fall in the radius of 20 km from the Jodhpur city whereas another two villages were selected 60 km far from Jodhpur city with poor infrastructure facility and poor non-farm employment. 30 respondents were randomly selected from each selected village.A total of 120 respondents were selected from four village for the study. Simple tabulation method was used. For determining the poverty status, income method was used. From the study, it is revealed that agriculture, livestock, non-farm-labor activities are the main factor for poverty assessment. Size of land holding is a crucial factor. Marginal and small land holding couple with low income, are the main reason for poverty. The percentage of earners in the family size groups and percentage of dependents is inversely proportionate.

Group Formation and Poverty Reduction among Farming Households in Selected Ar...Premier Publishers
Participation of farmers in local institutions has been known to increase their access to loan, promote and encourage savings and investment, hence alleviate their poverty level. This study therefore examined the determinants of group formation and the bi-causal relationship between group formation and poverty reduction among farming households. Data were collected using structured questionnaire. Analysis was done using descriptive statistics, group formation indices, Multidimensional Poverty Index (MPI) and Tobit regression model. The incidence of poverty and the average intensity of MPI were 50.58percent and 48.7 percent respectively. The Multidimensional Poverty Index (MPI) for the sampled households was 0.246. The Tobit regression result revealed that a unit increase in group interaction and group structure will decrease the level of poverty of the households by 0.0056 and 0.0043 respectively. Similar increase in group goals and group cohesion will lead to 0.0046 and 0.0045 decrease in poverty level respectively. Also, a unit increase in years of education decreases (p<0.01) poverty level by 0.0163. Group formation was truly exogenous to poverty reduction with no reverse causality. The study concludes that group formation positively affects the poverty status of farming households. This implies that a farmer’s participation in a group reduces his probability of being poor.

Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.

Financial Assets: Debit vs Equity Securities.pptxWrito-Finance
financial assets represent claim for future benefit or cash. Financial assets are formed by establishing contracts between participants. These financial assets are used for collection of huge amounts of money for business purposes.
Two major Types: Debt Securities and Equity Securities.
Debt Securities are Also known as fixed-income securities or instruments. The type of assets is formed by establishing contracts between investor and issuer of the asset.
• The first type of Debit securities is BONDS. Bonds are issued by corporations and government (both local and national government).
• The second important type of Debit security is NOTES. Apart from similarities associated with notes and bonds, notes have shorter term maturity.
• The 3rd important type of Debit security is TRESURY BILLS. These securities have short-term ranging from three months, six months, and one year. Issuer of such securities are governments.
• Above discussed debit securities are mostly issued by governments and corporations. CERTIFICATE OF DEPOSITS CDs are issued by Banks and Financial Institutions. Risk factor associated with CDs gets reduced when issued by reputable institutions or Banks.
Following are the risk attached with debt securities: Credit risk, interest rate risk and currency risk
There are no fixed maturity dates in such securities, and asset’s value is determined by company’s performance. There are two major types of equity securities: common stock and preferred stock.
Common Stock: These are simple equity securities and bear no complexities which the preferred stock bears. Holders of such securities or instrument have the voting rights when it comes to select the company’s board of director or the business decisions to be made.
Preferred Stock: Preferred stocks are sometime referred to as hybrid securities, because it contains elements of both debit security and equity security. Preferred stock confers ownership rights to security holder that is why it is equity instrument
<a href="https://www.writofinance.com/equity-securities-features-types-risk/" >Equity securities </a> as a whole is used for capital funding for companies. Companies have multiple expenses to cover. Potential growth of company is required in competitive market. So, these securities are used for capital generation, and then uses it for company’s growth.
Concluding remarks
Both are employed in business. Businesses are often established through debit securities, then what is the need for equity securities. Companies have to cover multiple expenses and expansion of business. They can also use equity instruments for repayment of debits. So, there are multiple uses for securities. As an investor, you need tools for analysis. Investment decisions are made by carefully analyzing the market. For better analysis of the stock market, investors often employ financial analysis of companies.

opinion leadership.
ABSTRACT
This paper compares the findings from different countries regarding the nature and
determinants of opinion leadership. The differences between white and black farmers
in one country far exceed the differences between black cultures in different countries.
White communities tend to have a bigger percentage of opinion leaders and socio-
economic status is an important barrier to accessibility. Socio-psychological
accessibility is a major constraint amongst white farmers, but not a factor whatsoever
in black communities. In black communities, on the other hand, distance or physical
accessibility is a serious constraint with the result that about 80 percent of the
opinion leaders consulted live within a 2 km radius. This and the fact that most of the
determinants normally associated with opinion leadership show a negative
relationships (as opposed to the positive correlations in white communities), creates
the suspicion that opinion leaders in black rural communities are neighbours or, more
likely, members of the extended family.
1. INTRODUCTION
Focusing communication messages on certain “influentials”, in the
assumption that their influence will come to bear in the further
diffusion to and influence on the other members of the target audience,
makes sense, especially if personal influence is called for but large

numbers or a wide change agent/client ratio make it difficult. This is
typically the case in many developing countries where there is usually a
shortage of extension workers to facilitate a quick dissemination of
agricultural messages. In this context it is fair to assume that the use of
influential farmers or opinion leaders can significantly contribute
towards an increased diffusion effect.
However, there is, according to Chege et al (1976) also evidence
suggesting that the “trickle-down” of information and influence does
not always occur to a significant degree. Lipton and Longhurst (1985)
and Parent and Lovejoy (1987) also come to the conclusion that the
influence of opinion leaders is grossly over-estimated.
This could be attributed to the wrong identification of opinion leaders,
but at least suggests that their influence is not really known and that
little is known about the factors contributing to their influence and
whether and to what degree these factors vary significantly between
different communities or cultures. This paper draws from a few studies
conducted in different countries, namely Uganda (Adupa & Düvel,
1999), Lesotho (Williams, 2005), and South Africa (Düvel, 2005), in
trying to find some answers to the above.
2. METHODOLOGICAL ASPECTS
The research approach used in the different surveys and on which this
publication is based, varied but had certain commonalities. In all cases
use was made of semi-structured interview schedules and the
identification of opinion leaders done by the socio-metric method. In
response to questions aimed at identifying opinion leadership,
respondents had to name the individuals that they would consult if
they wanted information or advice on a specific topic as well as those
actually consulted and those they regarded as knowledgeable. In most
projects preference was given to smaller populations rather than
samples of bigger populations, but invariably the nominated
individuals outside the group of respondents were also incorporated in
the analyses as far as certain data was concerned.

3. RESULTS
3.1 The scope of opinion leadership
Earlier research among white commercial farmers in South Africa
(Pienaar, 1983) left the impression of a relative small number of opinion
leaders having an influence on a large number of followers. This was
later found to be very unlikely (Düvel, 1996) and attributable to an
incorrect identification of opinion leaders. In response to a question
who respondents would consult if they were seeking information or
advice on a specific issue, there was a very clear reluctance, perhaps for
reasons of prestige or image projection, to nominate individuals as
opinion leaders that were not generally regarded to be very
knowledgeable. The fact that this led to an incorrect identification of
opinion leaders became evident when respondents were requested to
distinguish between individuals known as knowledgeable and those
really consulted.
This phenomenon, however, does not occur among black small-scale
farmers in the sense that they are more candid and open when
reporting about their consultation behaviour and they make little or no
difference between individuals that they would consult and those that
really are consulted. In these communities there is little danger of the
wrong individuals being identified.
As far as the number or percentages of opinion leaders in a farming
community are concerned, the findings of Williams & Düvel (2005)
from Swaziland appear to be pretty representative of the black farming
communities.
Accepting nominations of two or more to qualify as opinion leaders,
about 23 percent of the farming population can be termed opinion
leaders (Figure 1). In white commercial farming communities this
percentage is usually higher, varying from about 30 percent (Van der
Wateren, 1986) to as high as 40 percent (Bembridge & Burger, 1976), and
there are also clear indications of these opinion leaders to be more
monomorphic as opposed to the more polymorphic opinion leaders in
black farming communities.

3.2 Determinants of opinion leadership
Socio-economic status is generally accepted as being an important factor
in influencing opinion leadership or the pattern of consultations, in the
sense that followers usually seek advice from opinion leaders with a
higher socio-economic status (Rogers 1983), but if the difference in
status is too big the decreasing accessibility can be expected to prevent
the flow of information. This appears to be the case among the white
farmers (Düvel and Van der Wateren, 1988; van der Wateren 1986) but
it does not seem to apply to the black farmers. When black farmers were
asked to assess the accessibility of opinion leaders they previously had
categorized as having a lower, the same, or a higher socio-economic
status than themselves, there was no significant difference regarding
accessibility (Table 1).
Even the generalization made by Rogers (1983), namely that opinion
leaders have a higher socio-economic status than the followers, does not
seem to apply in many black cultures.

Other factors investigated that have opposite influences or relationships
in the black and white cultures are age, education, production efficiency
and farm size. The normal expectancy would be that opinion leaders do
not necessarily differ from their followers in age, but that they are better
educated (higher qualifications), have more contact with extension,
have bigger farms and are more productive or efficient farmers. In the
culture of the small scale black farmers almost the exact opposite
appears to be the case. The findings from Lesotho (Williams and Düvel,
2005) indicate that in black farming communities the opinion leaders,
particularly the strong opinion leaders, tend to be older, but have lower
levels of education (r = -0.257; p = 0.01) and are, based on production
efficiency, not better farmers at all. The opposite rather seems to be the
case.
The absence of a significant correlation between farming efficiency and
opinion leadership and the fact that only 34.5 percent of the
respondents seek advice from individuals that they regard to be more
efficient than themselves, seems to indicate that farming efficiency or
competence is not such an important issue in a farming environment
that is primarily subsistent in nature.
In Lesotho the strength of opinion leadership is negatively related to
contact with extension, which could be an indication that extensionists
are not aware of or not using the prominent opinion leaders yet and/or

that there is a negative relationship between opinion leadership and
perceived credibility of the extension service.
3.3 Accessibility of opinion leaders
Accessibility is probably, next to competence, the most important
dimension of opinion leadership. To function as an opinion leader, an
individual must not only be seen to have superior or a higher level of
knowledge, but there must also be the willingness on the side of
potential followers to seek his/her advice, and for that he/she needs to
be perceived as accessible. This accessibility has a physical and a socio-
psychological dimension:
(1) Physical accessibility.
If individuals form network links that require the least effort (Rogers
and Kincaid, 1981), people in the immediate environment are likely to
have more influence than those who are far, because they are physically
more accessible when their advice is needed. In the case of the white
commercial farmers, the distance or consultation proximity (distance
between follower and opinion leader) does not seem to influence the
consultations within the bigger community. However, in the small and
resource-poor farming situations (Figure 2), the physical distance can be
a serious limiting factor as is shown by the following findings from
Swaziland (Williams & Düvel, 2005).

About 50 percent of the opinion leaders consulted, live within 1 km
radius and almost 80 percent within a distance of 2 km. This could give
the impression that opinion leaders are mostly neighbours or members
of the own extended family.
(2) Socio-psychological accessibility
All surveys done among black farmers, whether in Uganda, South
Africa, Lesotho or Botswana, indicated that socio-psychological
accessibility is not a constraint. This is in contrast to the situation among
white commercial farmers as can be seen from Figure 3.

Accessibility
Figure 3: The accessibility of opinion leaders in the small-scale and
commercial farming situation (Düvel, 1996)
About 90 percent of all black opinion leaders were assessed to have a
high or very high accessibility compared to only about 50 percent in the
case of white commercial farmers. This means that accessibility is much
more critical in the culture of white commercial farmers and largely
determines the consultation pattern. Unlike the black farmers, where
there was hardly a difference in accessibility assessment between those
farmers classified as very knowledgeable and those actually consulted,
there were very significant differences in the case of the white
commercial farmers. The farmers classified as knowledge leaders, were
assessed significantly lower in accessibility, which largely explains why
they were not consulted or why their identification and involvement
did not have a significant influence on the total extension impact.

Further evidence of the unequal importance of accessibility is found in
the relationships between opinion leadership and certain determinants
of opinion leadership or factors associated with it.
3.4 Accessibility related factors
Where accessibility has been found to be a limiting factor this has led to
further investigations to better understand the concept and factors
related to it. These factors include (a) friendship versus kinship, (b) fear
of exposure and (c) reciprocity of influence
The assumption, that accessibility is particularly high among friends,
led to an analysis of the relationship between accessibility and
friendship. This relationship is highly significant among white
commercial farmers (r = 0.54; p = 0.0001), but absent in the black small-
scale farming sector. If anything it is the acquaintances that have the
edge regarding accessibility. This leads to the strong suspicion that
opinion leaders have their main influence within the extended family.
For this reason seniority rather than competence is related to opinion
leadership in black communities.
One of the major factors responsible for accessibility or the lack thereof
is fear of exposure.
The reluctance to consult somebody can in many cases be attributable to
the fact that consultation implies recognition of not knowing and thus
exposing oneself. This barrier can be overcome if there is reciprocal
consultation, i.e. if two individuals consult and advise each other in
different fields. Both these aspects were found to correlate significantly
in the white commercial situation but not in the black culture,
emphasizing once again that accessibility is not a problem or even an
issue in many black cultures
4. CONCLUSIONS
1. The fact that strategies based on opinion leadership don’t always
meet expectations must be ascribed to their wrong identification
in some cultures.

2. Accessibility is a critical dimension in some cultures, whilst it is
not a factor in others. However, more research is required to
understand this concept and the degree to which it is a constraint
in different cultures.
3. Opinion leadership strategies should be combined with other
local communication network phenomena.
4. An understanding of the diffusion process and its promotion may
be better served by a focus on negative opinion leaders, an area
largely overlooked by research.
