Selective imitation of the passive construction through modeling

Six 4- to 5-yr-old subjects were exposed to five sessions in which an adult model used passive sentences to describe a set of modeling stimuli. Probe stimuli, which the subjects were asked to describe without benefit of modeling and without selective reinforcement were interspersed among modeling stimuli. A matched group of control subjects received probletrials but no modeling trials. Both groups of subjects were subsequently tested on their ability to comprehend active and passive sentence forms. Every subject in the experimental group produced passive sentences on probe trials even though there was considerable variability in the number of passives produced. No control subject produced passives. The modeling procedure increased the comprehension scores of the experimental group above those of the control group though the scores of both groups were above chance. The results were contrasted with earlier studies in which modeling was ineffective in producing passive usage and in which comprehension of the passive was not demonstrated by even older children.     

Positive contrast obtained in reacquisition following interpolation of nonreinforced or partially reinforced trials

Two experiments investigated the effects of shifting from either nonreinforcement or partial reinforcement (PRF) to continuous reinforcement conditions (CRF). In the first experiment, three groups of rats were given food reinforcement under CRF conditions in a runway followed by regular extinction trials (RE), extinction trials where Ss were delayed for 30 sec before entering the empty goal box (DE), or CRF trials where Ss were delayed for 30 sec before entering the baited goal box (DF). Then all Ss were run on the delayed reinforcement condition (DF). In the final delayed reinforcement condition, group DE ran significantly faster than group DF, reflecting positive contrast. In the second experiment, four groups of rats were trained in a runway to receive either 4% or 18% sucrose reinforcers under either PRF or CRF conditions. Then all Ss were transferred to a Skinner box and bar presses were continuously reinforced, with each S continuing to receive the same sucrose concentration as before. The former PRF Ss, regardless of the reinforcer, bar pressed at a significantly higher rate in the Skinner box than the former CRF Ss. The evidence seemed to favor the view that the effectiveness of a reinforcer is not an absolute, unchanging quantity but rather depends on the historical context in which the reinforcer occurs.     

The importance of subject control in reinforcing brain stimulation

A comparison between the reinforcement strength of self-administered and externally imposed brain stimulation was undertaken. Rats performed on a chain schedule in order to receive brain stimulation, either selfadministered or imposed, during the second component of the chain. Response rates during the first component of the chain schedule indicated that self-stimulation was more reinforcing than imposed stimulation. In addition, contrast, both positive and negative, seemed to be present. It was concluded that reinforcement strength may be enhanced when the subject controls the presentation of reinforcement.     

Comparison of women engineers who persist in or depart from engineering

The current research examined differences between women engineers who persisted in an engineering career versus those who left engineering using a combination of two prominent theories of career change: social cognitive career theory (SCCT, Lent, Brown & Hackett, 1994; 2002) and integrated model of career change (Rhodes & Doering, 1983). The two groups of women did not differ in three domains of self-confidence or outcome expectations (engineering tasks, navigating organizational climate, or multiple roles), in vocational interests, or in workplace barriers. Women who continue in engineering do differ from those who leave in their experience of workplace supports and their levels of occupational commitment. Engineering turnover intentions and occupational commitment emerged as the two key variables that explained 33.4% of the variance in persistence in engineering careers. We discuss the implications of the results in terms of theoretical development and practical implications for organizations.     

Do We Need Grounding?

Many have been tempted to invoke a primitive notion of grounding to describe the way in which some features of reality give rise to others. Jessica Wilson argues that such a notion is unnecessary to describe the structure of the world: that we can make do with specific dependence relations such as the part–whole relation or the determinate–determinable relation, together with a notion of absolute fundamentality. In this paper I argue that such resources are inadequate to describe the particular ways in which some parts of reality give rise to others, and thus that we do in fact need grounding.     

Role of Mental Simulations in the Weight Loss Process

Two experiments were conducted to verify the influence of various mental simulations on the effectiveness and persistence of weight loss processes. In study one, 40 female students (aged 19–27, M = 23) who were eager to lose weight were randomly assigned to one of four groups: positive outcome simulation, process simulations, mixed simulations (process followed by negative outcome), and control (no simulations). Students from the mixed and process simulation groups lost significantly more weight after five weeks than participants from the outcome simulation and control groups. A total of 106 females (aged 19–45, M = 29) participated in study two, in which five types of mental simulations were tested. Besides the images used in study one, process followed by positive outcome simulations and negative outcome simulations were implemented. Results showed that process followed by positive outcome simulations lead to the highest persistence in the weight loss process, while process followed by negative outcome simulations induced the greatest reduction in weight. Both studies revealed self-regulatory benefits from mental simulations in difficult and long-term personal goal attainment.     

Sect‐to‐Church Movement in Globalization: Transforming Pentecostalism and Coastal Intermediaries in Contemporary China

After eight months of itinerant fieldwork across 17 provinces, I elaborate on how the largest Pentecostal group deeply localized in China, the True Jesus Church, has undergone sect‐to‐church movement through interactions among overseas, coastal, and inland churches in globalizing China. A critical intermediary role in this process has been taken by emerging coastal Fujian leaders, who have been successfully reforming not only their churches but also inland counterparts by tactfully utilizing overseas churches as stimuli, resources providers, and legitimizers for the transformation project. The Chinese fever of integration into the world and high status granted to the overseas are keys to smooth away the barriers of the traditionalist old guard. Accordingly, the originally enclosed, anti‐political, sectarian, spirit‐led group has turned more institutionalized, laity‐oriented, text‐based, and welcoming to the government and mainstream Protestantism.     

The arc of the rope swing: humour,poetry, and spirituality in Charlotte’s Web by E. B. White

This essay analyzes the classic American children’s novel, Charlotte’s Web, by E.B. White, which tells of a sophisticated spider’s rescue of a piglet who is being prepared for slaughter. The ‘arc of the rope swing' refers to a rope swing enjoyed by children in the novel; it is also a metaphor for the way White holds opposing forces in tension. Most noteworthy is the tension between poetic language and humour in the novel; White uses both to convey a sense of ultimate goodness and trust-in-being. Poetic language sets a contemplative tone (‘poetic pauses’) and conveys spiritual themes, including delight, wonder at the beauty of the natural world, ‘divine discontent’ (yearning), memento mori, sorrow and hope. In contrast, White’s ‘gracious humour’ is fast-paced and entertaining; it keeps the novel from being too preachy or solemn. His humour includes 1) wordplay (including the juxtaposition of incongruous words and images; dramatic irony; and puns ), 2) comedic characters (Wilbur as lovable buffoon, Charlotte as incisive wisdom figure) and 3) satire (scorn for human gullibility, arrogance and poor treatment of animals). White sharply satirises human arrogance and demonstrates the value of humility (embodied in Charlotte and Wilbur). The article also contains brief summaries of Charlotte's Web and of White's biography, and it concludes with a substantial set of “talking points” for discussing the novel’s spiritual themes with children.     

Equinox: portrait of a holistic school

This paper is a qualitative study of Equinox Holistic Alternative School, an elementary school in Toronto in its seventh year. There were a total of 27 people interviewed including teachers, parents, and students. The data indicated that the school is meeting its primary goal of educating the whole child.
