Business Strategies: Business-to-business Marketing

 

Business-to-business marketing is considered by companies to be a sound business strategy and more so when the electronic means is utilized (Ramsdell, 2000). For buyers, B2B marketplaces promise not only to deliver more competitive prices but also to rid the supply chain of a host of inefficiencies. For sellers, B2B creates a channel for their product distribution thus minimizing the cost of transaction attained when they themselves engage with the end-users of their products.

In business-to-business trade among buyers and sellers, the relationship involves complex products traded where there are high levels of inter-dependencies. In these situations it is necessary to co-operate in order to maximize the opportunities for the network of companies, and to build in protection measures against opportunistic behavior, either through trust developed over time, contracts, or a combination of both (Agrawal and Pak, 2001; Ramsdell, 2000; Hollad, 1996).

Factors such as trust and reputation are critical, and there is also the notion of cooperative strategies based on mutual benefit rather than the simplistic idea of maximizing revenues to individual organizations (Farrely and Quester, 2003; Archer and Yuan, 2000; Abramson and Ai, 1999). There is widespread research and anecdotal evidence of the importance of relationships in business-to-business markets and concepts such as the virtual value chain (Rayport and Sviokla, 1995) and cooperative supply chain structures (Holland 1996) extend the theory to market networks of separately owned organizations choosing to work closely together.

In practice, relationships in business-to-business marketing have come to mean trust that results in protective and complementary relations in Asia, and will thus include the sharing or pooling of resources (Hamzah-Sendut et al, 1990 in Abramson and Ai, 1999, p.10). These factors are all part of the Asian concept of guanxi, the six key constructs of which being: Mutual trust between parties; Commitment towards mutual benefit; Empathy towards all parties; Maintenance of relationship; Provision of favors to partners; and Full reciprocation of favors; (Abramson and Ai, 1999, p.10).

Two adjacent players--the buyer and the seller--usually share information at each stage of the supply chain and transaction process, and the nature and amount of what they share depends on the quality of their relationship (Agrawal and Pak, 2001). Thus, the successful exchange of information in the transaction of B2B reflects the amount of investment and trust buyers and sellers bestow to each other.

The B2B relationship is even more controversial in the emerging market of B2B retailing. The business is lucrative where Internet business-to-business sales will reach $1.3 trillion by 2003 and; by 2004, business-to-consumer sales will reach $100 billion (Lord, 2000). Aside from the potentially huge market offered by the internet, E-commerce technologies provide effective and efficient ways in which corporate buyers can gather information rapidly about available products and services, evaluate and negotiate with suppliers, implement order fulfillment over communications links, and access post-sales services (Chaston and Mangles, 2003). From the supplier side, marketing, sales, and service information is also readily gathered from business partners. Building and maintaining B2B relationships is the key to success in e-commerce and, unless service is maintained, customer loss may result, more than offsetting any cost efficiencies due to introducing e-commerce technology (Archer and Yuan, 2000). Since the core of e-commerce is information and communications, support for managing customer relationships particularly trust is of primary consideration in the buyer-seller relationship (Archer and Yuan, 2000).

Although there is some evidence of a move towards electronic markets, there is also strong evidence to support the hypothesis that electronic communication technologies will forge closer relationships rather than create more fragmented ones. This is particularly true in business-to-business markets where the levels of interdependencies between buyers and sellers are typically extremely high compared with business to consumer markets (Johnston and Lawrence, 1988, Konsynski and McFarlan 1990).

Sample of a Significance of the Study

 


Significance of the Study

            This study shall determine the workplace practice and application of geographic information system (GIS) in the public health sector and how the education provided in the academe is compatible/incompatible with the actual practice of spatial analysis. Furthermore, this study shall illustrate the importance of spatial modelling and planning in the training of masteral level students in solving the spatial problems encountered in the workplace. This will be beneficial to educators, students and GIS practitioners alike in determining the capabilities that are required in the public health sector.

Sample of Research Questions and Hypothesis

 


Statement of the Problem

            This proposed paper shall evaluate the spatial analysis models and in the public health sector and shall be compared to what is taught in the masteral level. Essentially, the study shall focus on the problems encountered in the spatial modelling and planning in the public health and how the education system helps/lacks in the training of the students.

            Specifically, two questions shall be answered: (1) What are the problems, factors and challenges facing the public health sector in GIS spatial modelling and how does the training of the masteral students addresses this problem? (2) Can the masteral training of the public health practitioners support and address the spatial problems encountered in the workplace application?

Hypothesis

            This study shall test the following null hypothesis:

Public Health Schools provide inadequate GIS education for the actual applications of spatial methods and analysis in the public health sector.

Sample of a Conceptual Framework

 


Conceptual Framework

This paper shall utilize the mathematical modelling by Arbia, G., Griffith, D. and Haining, R. (1999). The purpose of adopting this approach using maps and error processes with simple but well-defined properties is to understand better how different elements of the situation, individually and together, contribute to the final propagated error. The problem with using real maps (rather than artificially generated maps) is that real maps usually have complex structures so that it may not be clear the extent to which aggregate statistics computed to measure the severity of the error problem are an aggregation across many types of quite different map segments with different structures. Usually, real errors are not known for any data set, and unless their structure is uniform across the map, the same problem for interpreting aggregate statistics could arise.

Using formal mathematical modeling, rather than just simulation, means that where theoretical results can be obtained they can be used to check simulation output before the simulation is used to obtain properties that are not accessible to mathematical analysis. Furthermore it is only through formal mathematical modeling, leading to closed-form expressions, that a rigorous study can be undertaken that yields quantitative and qualitative insights as to how different elements contribute individually or interactively to error propagation. The formal expressions make the contributions explicit, and regression (adding maps) and ANOVA (ratioing) are used to quantify the relative contributions of each term in the expression. Where theoretical results have not been obtained, as in the case of ratioing, simulation alone, even with regression analysis of the outputs cannot produce the same quality of evidence because of the dangers of model misspecification in using regression.

Public Health and GIS, Mismatch of Job Skills and Theoretical Training

 


Abstract

 

            The escalation of geographical information system (GIS) application in several fields such as environment analysis has been progressive in relation to poverty, crime and education (Duecker and DeLacey, 1990, Huxhold, 1991, Harris and Batty, 1993). However, public health lags behind these fields in its use of GIS (Urban and Regional Information Systems Association, 1994). This limitation had largely been highlighted in the literature (see Fuertstein, 1987; Drummond, 1995; National Association of  Country Clubs Off, 2002). However, the development of measures and strategies that could enhance GIS in public health had been proposed in terms of location, area and even in data processing (Queralt and Witte, 1998; McLafferty, 1998; Rushton & Frank, 1995).

The area of GIS and Public Health has risen to prominence in the past two years with the recognition that health surveillance practices and health service allocations need to become more sensitive to the needs of people in local geographic areas. The collection, storage and manipulation of geographic information have undergone a revolution in recent years with the development and widespread availability of GIS software. Many health professionals can benefit from further education in this area, and with their new knowledge, they can influence the progress of health surveillance, environmental health assessment and the geographic allocation of health resources.

            This development provide a significant catalyst for the advancement of public health GIS and the use of geospatial data through the Internet (Croner, 2003). They provide timely stimulus for the delivery of public health geospatial information for community, state, and national uses. They portend important changes. Based on emerging geospatial infrastructure in the twenty first century.

A GIS can be a useful tool for health researchers and planners because health and ill-health are affected by a variety of life-style and environmental factors, including where people live, characteristics of these locations (including socio-demographic and environmental exposure) offer a valuable source for epidemiological research studies on health and the environment. Scholten and Lepper (1991),

With the huge increase in the use by planners of geographic information systems (GIS), a need has developed for accompanying statistical routines to aid in the analysis and interpretation of geographical data particularly spatial analysis. (Levine, 1996)  Many planners use GIS to isolate geographical areas, subpopulations, land uses, and road systems according to various search criteria, extracting objects on the basis of geographical or attribute conditions. The existing GIS packages are very sophisticated tools for geographical and database operations. They can conduct a wide variety of different overlay operations: creating buffers around objects, selecting objects by their proximity to other objects, unioning smaller objects into bigger ones and splitting larger objects into smaller objects, as well as implementing a whole range of database functions (e.g., conditional queries, object queries). (Levine, 1996)

The information contained in a GIS is not in itself unique. Rather, the uniqueness of GIS lies in its ability to integrate pieces of existing spatially-referenced information in unprecedented ways. Some go so far as to say that, based on the new perspectives offered by GIS, it might even constitute a new discipline (Goodchild, 1990).  Whether or not this is a realistic assessment, there is little doubt that GIS offers great benefits in the constructivist, holistic model upon which it is based--a perspective that is gaining attention among educators (Boyer and Semrau, 1995).

Many geography educators hold that enhancing geography education must include integrating spatial technologies such as GIS (Nellis, 1994).  GIS research has in turn expanded to include theoretical and practical questions about its place in the framework of education, (Suit, 1995) since lack of such understanding would undermine the potential of the tool itself (Donaldson, 1999).  Likewise, if GIS is to evolve into a significant force in education, more thought needs to be given to how it is implemented and used in classrooms. Most geography educators concur that successful GIS implementation will not be possible without a combination of (1) acknowledgment of its usefulness by teachers and administrators; (2) a concomitant level of financial support for this technology; (3) the provision of teacher training; and (4) the creation of networks to supply teachers and administrators with the entry-level and advanced information they need to implement GIS.

This study shall investigate the disparity in terms of the curriculum of spatial methods in the Masteral level and what is taught in Schools of Public Health using GIS (geographic information systems) and what employers, particularly in the Public Health sector both private and public expect these students to be able to do using spatial analysis tools competency. Moreover, this study shall include the state and local public health offices, public health research firms, and GIS educators in order to determine if their employees coming out of these schools possess the necessary skills or are they being taught on the job to use GIS.

Future Methods of Laundering Cash



The relationship between technology and structure has been the topic of much writing and research (Woodward, 1965; Perrow, 1967; Thompson, 1967; Hickson, Pugh, and Pheysey, 1969; Mohr, 1971; Hage and Aiken, 1969; Barley, 1986). Although the accumulation of research studies has modified the concept of technological imperative, technology is still considered an important variable in relation to organizational structure (Rousseau, 1979). Yet, after decades of research relating organizational technology to organizational structure, "the evidence for technology's influence on structure, is at best, confusing and contradictory" (Barley, 1986: 78). The same may be said for the multitude of conceptions and methodologies employed in such studies (Rousseau, 1979). While technology may be generally defined as the transformation of organizational inputs into organizational outputs (Perrow, 1967; Rousseau, 1979), numerous definitions and operationalizations at varying levels of analysis and contexts demonstrate the diversity of technology research (Comstock and Scott, 1977; Rousseau, 1979; Fry, 1982). Despite this diversity, little attention has been paid to the effects of technology over time. Cross-sectional research has typically focused on existing technologies and corresponding formal organizational structures. The majority of these cross-sectional studies treat technology as the independent variable, based on an assumption that organizational technology is inflexible and, correspondingly, that there is a need for structure to adapt to the requirements of technology. These assumptions are questionable. Technology can be a flexible organizational strategy that can be modified by an organization's structure, in particular, the informal structure. Structural arrangements act as the conduits of technological change and, as such, may influence organizational technology as well as be influenced by it. Investigation of the effects of a change in technology may illuminate the process by which structure affects technology, or vice versa. Few studies relating technology to structure have considered the relationship between organizational structure and power. Structural position is an important source of power in that it provides access to people, information, and other resources. As Pfeffer (1981) noted, power is first and foremost a structural phenomenon. Likewise, power strengthens existing structural configurations. Those in power seek to maintain power by reinforcing the existing organizational structure (Pfeffer, 1981). Thus, a change in structure may necessitate a change in the distribution of power, and vice versa.

Although minor, incremental changes in power and structure may occur gradually over long periods of time, the likelihood of a major restructuring may only occur when the organization encounters an "exogenous shock" (Barley, 1986: 80) such as the implementation of a new technology. Such a shock might be conceptualized as a sudden, dramatic increase in uncertainty (Tushman and Anderson, 1986). Attempts to reduce uncertainty may foster changes in interaction patterns, with those able to cope with uncertainty adjusting their social location and increasing their power (Salancik and Pfeffer, 1977; Tushman and Romanelli, 1983). Thus, it is possible that a change in technology may produce changes in structure, power, or both. However, as Pfeffer (1981) noted, stability, not change, is typical of the distribution of power and influence in most organizations. Those in power seek to perpetuate their power advantage. Such processes as commitment to previous decisions, institutionalization of beliefs and practices, and the ability of those in power to generate additional power contribute to stability (Pfeffer, 1981). Likewise, structural patterns of interaction become institutionalized over time and contribute to organizational stability. Thus, while a technological change may provide the opportunity for a redistribution of power and organizational structure, it does not guarantee it.

Unfortunately, even the cleansing dirty money through money laundering procedures has also been affected by technology. Example of these changes includes the new drug trafficking routes are spawned in Africa and the lower regions of the old Soviet regime, the list of countries more vulnerable to money laundering widens. Perhaps more dangerous is the absence of implementation of anti-money laws or even ratification of the 1988 Vienna-U.N. Drug Convention. (Bureau of International Narcotics and Law Enforcement Affairs, 1998) The INCSR lists Aruba, Colombia, Mexico, the Netherlands Antilles, Nigeria, Singapore, Turkey and Venezuela. Just as important, the anti-money laundering laws that governments enacted in the early 1990s are now no longer sufficient, especially given the increase in non-drug crimes, the use of new technologies, and more sophisticated ways to move money.

Moreover, the proliferation of financial crimes include the more common types of financial frauds and new variations, especially the use of prime bank guarantees, phony or fictitious letters of credit, counterfeit or stolen bonds, and other monetary instruments offered as surety for loans, and other scares. Some of the new methods include the use of secret telex codes for bank-to-bank transactions in order to move $42 million in cash from the Hong Kong and Shanghai Bank in Jakarta. (Bureau of International Narcotics and Law Enforcement Affairs, 1998) The use of fake certificates of deposit drawn on other branches of an international bank that can range from $10 million to $25 million recently occurred. "`Fraudsters' will also use counterfeit letters of agreement, drawn on bank letterheads, seemingly vouching for a client from another branch of that bank," or confirming the approval of a bogus deal.  

Similarly, professional money launderers differ little in their money management than corporate money managers. Money brokers and transnational criminals collaborate to minimize their risk, partly through diversification of the means to transport, convert cash, or both, as well as to layer and integrate the laundered funds.(532)

Furthermore, banking is increasingly global, inter-connected, and operates twenty-four hours. Large multinational banks have global branch and subsidiary networks as well as correspondent relationships. Correspondent banking enables launderers to initiate transactions through the weakest link in the bank. Once launderers start a bank relationship, they can quickly move money globally within the bank. (Bureau of International Narcotics and Law Enforcement Affairs, 1998) At the June 1996 International Conference of Banking Supervisors, banking supervisors from 140 countries agreed to adhere to twenty-nine recommendations "designed to strengthen the effectiveness of supervision by both home and host-country authorities of banks that operate outside their national boundaries."(p 154) The recommendations were incorporated into a report by the Basle Committee on Banking Supervision, issued in October 1996. Home supervisors must be able to assess "all significant aspects of their banks' operations, using whatever supervisory techniques are needed, including on-site inspections." Means to overcome impediments to effective consolidated supervision are suggested. The Basle report sets forth "guidelines for determining the effectiveness of home country supervision, for monitoring supervisory standards in host countries, and for dealing with corporate structures which create potential supervisory gaps." Additional guidelines are provided for host country supervision.

Concurrently, when the recommendations conflict with bank secrecy or similar legislation in certain countries, supervisors have agreed to use best efforts to amend the secrecy legislation. Countries with further recommendations were reviewed prior to the international meeting scheduled for October 1998. (Bureau of International Narcotics and Law Enforcement Affairs, 1998) Much competition exists globally to attract high net-worth individuals and companies as private banking clients. The transactions of these clients are treated confidentially. Such customers are treated with more deference and receive various types of personal services. A concern exists that, in the competition to attract and maintain these clients, financial institutions or their officials may suspend or not implement anti-money laundering and other due diligence procedures.

In addition to that, the use of microchip-based electronic money for financial transactions, via smart cards and the Internet, has the potential to revolutionize the means for laundering money. Some new cyberpayments systems are engineered to be an electronic emulation of paper currency. Cybercurrency has the attributes of conventional currency: a store of value; a medium of exchange; a numeraire; potential anonymity; and convenience. Other features include transfer velocity--an almost instant electronic transfer from point to point--and substitution of electrons for paper currency and other physical means of payment. Cyberpayments also include other payment components, such as cyberchecks, cybercredit, cyberdebit, and so forth. This development requires close attention because the use of microchip and telecommunications technologies adds some significant new dimensions for law enforcement.

The existence of cyberpayments also include other payment components, such as cyberchecks, which emulate paper checks, cybercredit, cyberdebit, etc. Cyberpayments raise the issue of whether such payments can be made subject to monetary reporting and supervision measures. Law enforcement issues that will arise include fraud, counterfeiting, and computer hacking. High-speed, worldwide transfers add complexity to law enforcement's ability to trace criminal activity and recover illicit proceeds. (p. 512)

Other challenges to anti-money laundering enforcement include the counterfeiting of currencies and other monetary instruments, especially bonds, the rise in contraband smuggling, the acquisition of banks and other financial institutions by suspected criminal groups, and the resort by criminals to the use of smaller, pass-through banking, and electronic cash systems. As a result of the occurrence of financial crimes and money laundering with varying degrees of regularity in more than 125 jurisdictions, a continuing concern exists that some governments still have not criminalized all forms of money laundering.
