TL;DR: PACKAGING often plays a critical role in a firm's marketing mix as mentioned in this paper, and negative packaging attributes can sometimes enhance product quality, and serve as a vehicle for promotion.
Abstract: PACKAGING often plays a critical role in a firm's marketing mix. A negative packaging attribute can sometimes enhance product quality. As part of the product and distribution mix, it performs the functions of protection and containment. Perhaps more importantly, packaging serves as a vehicle for promotion. In today's self-service economy, packaging provides the manufacturer with the final opportunity to persuade prospective buyers prior to brand selection. Shoppers, as they pass down the aisles, are "exposed" to packages just as they are to print media or other forms of promotion.

TL;DR: The results demonstrate that the potential exists for microbial thiosulfate oxidation to increase both dark assimilation of carbon dioxide and the utilization of organic compounds in the sea.
Abstract: The effect of thiosulfate on dark assimilation of carbon dioxide in shallow marine environments was investigated in order to explain the recent discovery of bacterial thiosulfate oxidation in aerobic, open ocean seawater. The results demonstrate that the potential exists for microbial thiosulfate oxidation to increase both dark assimilation of carbon dioxide and the utilization of organic compounds in the sea. Thiosulfate-stimulated microbial activity may be caused not only by chemoautotrophic sulfur bacteria, but also by heterotrophic species which oxidize thiosulfate to tetrathionate. Measurements of dark assimilation of carbon dioxide made at different incubation times indicate that great care must be taken both in experimental procedure and in interpretation of results obtained with the dark assimilation technique.

TL;DR: The insertion loss for multibar magnetostatic surface-wave (m.s.w) transducers has been calculated from a "small" loss microstrip-transmission line model as mentioned in this paper.
Abstract: The insertion loss for multibar magnetostatic-surface-wave (m.s.s.w.) transducers has been calculated from a ‘small’-loss microstrip-transmission-line model. Experimental results for 2-bar and 8-bar parallel-strip and 4-bar π transducers are in excellent agreement with theoretical predictions. The 8-bar parallel-strip-transducer delay line gives a major bandpass response at 3.1 GHz, corresponding to an m.s.s.w. wavelength of 300 μm. The insertion loss is 11 dB, the 10 dB bandwidth is 70 MHz and adjacent sidelobes are 16 dB down.

TL;DR: Findings indicated that learned helplessness was associated with less phasic skin conductance responding, while depression wasassociated with greater responding to uncontrollable aversive events, suggesting that there may be different underlying deficits involved in depression and learned helplesshood.
Abstract: The present study was designed to assess whether the physiological correlates of learned helplessness are similar to the physiological response patterns found in naturally occurring depression. One group of subjects was pretreated with a series of inescapable aversive tones, and the degree of impairment measured on a subsequent solvable anagram solution task. These subjects were compared to a group pretreated with escapable aversive tones, and a control group which passively listened to the tones without attempting to escape them. Half of the subjects in each group were depressed as measured on the Beck Depression Inventory; the other half were nondepressed. Results indicated that depressed-control group subjects demonstrated impaired performance at solving anagrams relative to nondepressed-control group subjects. Inescapable noise produced parallel deficits in nondepressed subjects, thus demonstrating a similarity of impairment in naturally occurring depression and laboratory-induced learned helplessness. More importantly, findings indicated that learned helplessness was associated with less phasic skin conductance responding, while depression was associated with greater responding to uncontrollable aversive events. These data suggest that there may be different underlying deficits involved in depression and learned helplessness.

TL;DR: The authors compare deprogramming with exorcism, thought reform, and resocialization, and offer insight into how members of the anticult movement justify their own involvement in "coercive conversion."
Abstract: This paper compares deprogramming with exorcism, thought reform, and resocialization, and offers insight into how members of the anticult movement justify their own involvement in "coercive conversion." It serves as a fitting, if ironic, close to this issue on conversion and commitment in contemporary religion.

TL;DR: A battery of tremour and tracking tasks has been designed and evaluated, it is portable, and easy to administer and score, and evaluates neurological functions associated with steadiness, reaction time, speed, and co-ordination of the upper extremities.
Abstract: It has been known that tracking tasks can be useful for detecting small but significant changes in neurological function. However the size, cost and complexity of the equipment have, to date, precluded their widespread use for evaluation of clinical trials. In development for nine years, a battery of tremour and tracking tasks has been designed and evaluated. It is portable, and easy to administer and score. It evaluates neurological functions associated with steadiness, reaction time, speed, and co-ordination of the upper extremities. Instrumentation includes a central electronics package with power supply and test timers, a digital data readout, a television display, a chart recorder, and position, force, and accelerometer transducers. Available tests include force steadiness, resting and sustention tremour, and random, sinusoid, step and critical tracking in pursuit and compensatory modes. Data analysis can be online or offline.

TL;DR: In this paper, a classification system for analysis of specific verbal marital communications utilizing videotaped Stimulus-Modeling procedures is described, and the results indicate the need to combine modern technology with modeling procedures in marital counseling.
Abstract: The development of a classification system for analysis of specific verbal marital communications utilizing videotaped Stimulus-Modeling procedures is described. This instrument is applied to a study measuring the relative effects of modeling, modeling plus videotape feedback, and verbal counseling procedures on 30 couples seen in marital counseling. The Stimulus-Modeling (SM) tape portrays both functional and dysfunctional marital communicational patterns. Findings reveal that specific marital verbal behaviors can be operationalized and reliably measured. When these behaviors are depicted through modeling procedures and combined with videotape feedback, they are effective in changing specific problematic verbal behaviors. The results indicate the need to combine modern technology with modeling procedures in marital counseling.

TL;DR: Comparisons supported previously obtained data indicating that the regeneration blade should be considered as a typical blade organ rather than a morphological variant of the stipe, and raises questions about possible physiological differences which may exist between stipe and blade organs in this plant.
Abstract: Quantitative electron micrograph analytical techniques were used to study cytological changes associated with the process of dedifferentiation and redifferentiation in mature, specialized cells of the stipe in the brown algaSargassum filipendula following wounding. Early cytological changes associated with this process appear to be those involved with formation of a protective layer of material at the wound surface. An increase in the volume of cytoplasm occupied by mitochondria, dictyosomes, and type A and B vesicles was evident by three days postwound. Cytoplasmic volume occupied by chloroplasts decreased during the early stages of wound reaction while the development of internal membranes (thylakoids) in these organelles increased. Cells at the cut surface eventually differentiated into one of two types of tissues: 1. A wound surface epidermal layer similar in cytological aspect to the epidermal layers of the intact and regenerated plant. 2. A meristematic “regeneration bud” from which developed the blade-like regeneration growth. The morphology and anatomy of the tissues of the regeneration blade resembled those of the blade of the intact plant rather than those of the stipe from which it originated. Percent difference values were obtained by comparing cytological features of the tissues from the regeneration blade with those of the intact stipe and blade. The comparisons supported previously obtained data indicating that the regeneration blade should be considered as a typical blade organ rather than a morphological variant of the stipe. Results of this study raises questions about possible physiological differences which may exist between stipe and blade organs in this plant.

TL;DR: In this article, a competency-based direct practice curriculum for graduate social work education is presented, where admission and graduation requirements related to five knowledge-skills areas are outlined: interpersonal behavioral control, judgment and decision making, contracting and goal setting, selection and application of change method, and assessment of outcomes.
Abstract: This paper explicates a competency-based direct practice curriculum for graduate social work education. Specifically, admission and graduation requirements related to five knowledge-skill areas are outlined: (1) interpersonal behavioral control, (2) judgment and decision making, (3) contracting and goal setting, (4) selection and application of change method, and (5) assessment of outcomes. The implications of this empirically based educational model are discussed in terms of accountability and congruence between educational objectives and practice behaviors.

TL;DR: In this article, a method of moments is developed and applied to the identification of liver disorders arising in biosciences, where the moments are used to compute the elements of an N × N matrix A such that X ′( t )= AX ( t )+ W ( t ), t > 0.
Abstract: The method of moments is developed and applied to the identification problem arising in biosciences. In particular, we are concerned with computing the elements of an N × N matrix A such that X ′( t )= AX ( t )+ W ( t ), t > 0. Here the data for X ( t ) and W ( t ) is obtained from experiments. Using the moments, mom n ( X ) = ∫ ∞ 0 t n X ( t ) dt , of X ( t ) and W ( t ), we obtain a linear system of equations for the elements of A . An application to a four compartmental model for studying liver disorders is given. Numerical examples of our results are discussed in detail for flourescence decay experiments.

TL;DR: The effect of repeated exposure to prevoiced and voiced stimuli on the voiced/voiceless category boundary was compared for monolingual native English speakers and bilingual native speakers of Thai as mentioned in this paper.
Abstract: The effect of repeated exposure to prevoiced and voiced stimuli on the voiced/voiceless category boundary was compared for monolingual native English speakers and bilingual native speakers of Thai. The English speakers, for whom the two adaptors were members of the same phoneme class, showed equivalent shifts towards the adapting stimulus under both conditions. The Thai subjects, who perceived the two adaptors as belonging to two distinct phoneme classes, showed a shift of the voiced/voiceless boundary only for the voiced adaptation condition; exposure to the prevoiced adaptor had no effect. Since Eimas and Corbit (1973) first demonstrated selective adaptation for the linguistic feature of voicing, their technique has been used with other categories and classes of speech (Cooper & Blumstein, 1974; Eimas, Cooper, & Corbit, 1973; Morse, Kass, & Turkienicz, 1976). The procedure is simple: repeti­ tion of a token taken from one end of a linguistic continuum leads to a shift in the category boundary, towards the adapting stimulus. In the original demonstration, subjects adapted with a Iba/ found stimuli previously lying on the Iba-pal boundary to be more Ipal-like, while those exposed to Ipa/ re­ ported just the reverse. The first studies of selective adaptation used as adaptors stimuli chosen from the extreme ends of the continuum, stimuli which could be considered "good" exemplars of their phoneme class. It was, therefore, of both empirical and theoretical interest to test the effect of adaptors closer to the category boundary, which, although they were not as "good" exemplars acoustically, would still be unambiguously perceived as belonging to one or the other phoneme class. Using the voice onset time (YOT) continuum, ,Anderson (1976) and Miller (Note 1) found that stimuli close to the preadaptation category boundary produced less adaptation than more extreme stimuli. Miller (Note 1) interpreted these results to support the existence of feature detectors selectively tuned to overlapping distributions of YOT values. The closer the stimulus to the optimal values, the more strongly the feature detector fires, and the greater the This research was funded by Grant R03 MH 26168 from NIMH and FRAP 11184 from the Research Foundation of the City University of New York. The author wishes to thank Drs. F. S. Cooper and A. M. Liberman for making available the facilities of Haskins Laboratories, Ralph Bianca for gathering the data, and the Thai Student Association of Columbia University for providing volunteers. Above all, thanks are due to the Thai students themselves, who endured not only the experimental sessions, but a 3-h round-trip subway ride as well. 347

TL;DR: The application of low-power Schottky integrated-circuit logic in the design of a 10-Mzps parallel-output array generator for Walsh functions is presented here.
Abstract: Recent development of circuits for generating parallel-programmable and serial-programmable Walsh functions with a high degree of orthogonality is discussed. The realization of these circuits leads to the demand for highly integrated digital circuits with multiple outputs triggered synchronously. Circuits capable of high speed and low input power have just recently come into production. The application of low-power Schottky integrated-circuit logic in the design of a 10-Mzps parallel-output array generator for Walsh functions is presented here. The circuit is designed, built, and tested and the orthogonality error for the Walsh functions is discussed.

TL;DR: Behavior elicited from the lateral hypothalamus of rats became stronger as a function of experience with stimulation and available goal objects, and changes in latency and duration were the most sensitive measures of this response emergence.
Abstract: Behavior elicited from the lateral hypothalamus of rats became stronger as a function of experience with stimulation and available goal objects, and changes in latency and duration were the most sensitive measures of this response emergence. The strength of an elicited behavior was not diminished by a period of time-off from stimulation, indicating that the changes were relatively permanent; and the performance of an already established behavior remained stable during the emergence of a new behavior. Animals with extensive deprivation experience also displayed response emergence. These findings are consistent with the argument that learning variables influence the development of elicited behavior. However, experience with the stimulation apparently was not the primary determinant of response dominance in situations where different goal objects were made available simultaneously.
