Rebates, inventories, and intertemporal price discrimination

We demonstrate that universally redeemed rebates can increase manufacturer profits by reducing the incentives of downstream retailers to hoard inventories when optimal wholesale prices vary predictably over time. By bypassing retailers and making direct contracts with buyers, the manufacturer can increase the variations in effective prices paid by consumers without concomitantly creating larger incentives for retailers to hold inventories. During profitable, high-demand periods, manufacturer revenues are ordinarily constrained by'competition'from retailer inventories, thus limiting profits. However, by selectively offering rebates to consumers while maintaining high wholesale prices, low-demand periods can be accommodated without inducing retailer hoarding.     

Race–gender Differences in Risk and Protective Factors among Youth in Residential Group Homes

Analysis reported here examined youth in residential group home placements in order to better understand how sexual behaviors, drug use, and environmental experiences differ by race and gender subgroups. Data were collected from 336 youth aged 14–21 residing in one of 41 group homes in Maryland. Chi square and logistic regression analyses were done to determine differences on study variables among the race-gender groupings. Results demonstrate not only significant health concerns overall but notable differences were also found between race-gender subgroups. Findings suggest that found race-gender subgroup differences might be informative for tailoring programming for youth of residential group home settings.     

Electronics: The new revolution

Electronics has produced a succession of remarkable accomplishments within the lifetime of living men. Yet, new developments in the field are so vast and exciting that they may be viewed as the advent of an Electronic Revolution comparable to the Industrial Revolution.     

Quantifying Littered Cigarette Butts to Measure Effectiveness of Smoking Bans to Building Perimeters

Abstract

Objective: The authors estimated the number of violations of a university policy that prohibited smoking within 25 ft of all campus buildings. Participants: The project was conducted by 13 student researchers from the university and a member of the local public health department. Methods: Students quantified cigarette butts that were littered in a 30-day period inside the prohibited smoking area of 7 campus buildings (large residential hall, small residential hall, administrative building, 2 academic buildings, campus cafeteria, and student union). Results: Investigators found a total of 7,861 cigarette butts (large residential hall: 1,198; small residential hall: 344; administrative building: 107; 2 academic buildings: 1,123 and 806; campus cafeteria: 2,651; and student union: 1,632). Conclusions: Findings suggest that there is low compliance with the university's smoking policy. The described project may be repeated by students at other universities as a method to advocate for policy change.     

Rising prices,financial statements and fundamental research

Adequate consideration cannot be given to the subject of inflation accounting without a rigorous reappraisal of the nature and usefulness of published financial statements. It is argued that much fundamental research is a necessary prerequisite for the evaluation of methods of accounting in a period of inflation. Such research should begin with a consideration of the purposes to be served by the publication of financial statements. A framework is presented for such fundamental research and the results of some preliminary work outlined to assess the usefulness of financial statements in providing information to assist investors to make investment decisions. The use of financial statements by investors for this purpose is one of a number of possible objectives for financial statements.     

Manufacturing productivity

The general theory of engineering systems suggests that to produce desired order (to make a machine that works, to reduce the entropy, or even to improve productivity) the agent needs access to sources of (i) information, or useful messages; (ii) energy, or motivation; (iii) resources, including skills. A manufacturing economy, being an engineering system, obeys the same rules, so that an objective examination of 11 of them may be instructive. Since Belgium has no native energy and very few native resources, her post-1968 success in raising her productivity suggests significant improvement in her information systems. The author suggests what this improvement may have been.     

Economic lot disposition policies for single attribute sampling plans

Traditionally, single sampling plans have provided but two possible lot disposition policies, either to (1) accept or reject and screen, or to (2) accept or reject and scrap. This is particularly true of statistical designs. Economically based plans, however, provide a framework wherein several lot disposition policies may be invoked in accordance with estimated lot quality. This paper illustrates how such designs may be realized.     

The nature of action learning

Action Learning has developed to such an extent that there is now a demand to ‘know’ what it is. There is one way, and one way alone, of getting to ‘know’ what action learning is, and that is by doing it. For those who most clamour to ‘know’ what something might be are usually the victims of an educational system that leaves the vast majority who pass through it ignorant of the meaning of the verb to ‘know’ .... If, for example, I am asked “Do you know that woman?”, it is most probable that the questioner does not ‘know’ what he is asking me. Does he mean “Do I know her name? Or where she lives? Or am I able to introduce him to her? Or what she does for a living? Or do I recognise her by sight? Or have I been to bed with her? And, if so, what progress did I make?...” Thus, with action learning: “Have I read a book about it? Or attended a seminar at which somebody was trying to sell places on an action learning programme? Or visited a set of participants meeting as part of such a programme? Or tried to organise real persons tackling real problems in real time, and trying thereby to learn with and from each other? Or been an active participant myself in such a programme?...” To ‘know’ what action learning is, one must have been responsibly involved in it; since this cannot have been done merely by reading about action learning, it is impossible in this, or any other, note to convey more than the vaguest impression of what this educational approach may be. The day action learning becomes explicable in words alone will be the day to abandon the practice of it.     

Exchange curves for fixing batch quantities

The problem considered is that of choosing batch quantities to minimize costs, subject to the constraints that neither overall set-up costs nor overall set-up time can be increased beyond certain limits. Theoretical and graphical solutions are obtained for two possible formulations of the problem, and a simple practical procedure is suggested.
