Gelatin‐Filtered Consommé: A Practical Demonstration of the Freezing and Thawing Processes

ABSTRACT: Freezing is a key food processing and preservation technique widely used in the food industry. Application of best freezing and storage practices extends the shelf‐life of foods for several months, while retaining much of the original quality of the fresh food. During freezing, as well as its counterpart process, thawing, a number of critical physiochemical processes take place, including freeze concentration and freezing‐point depression. As a start to understanding the complexities associated with frozen foods, Food Science students should be able to describe and explain what occurs during the freezing and thawing of an aqueous solution. A modern cooking technique, gelatin‐filtered consommé, illustrates all of the phenomena associated with the freezing and thawing processes in a memorable, edible, hands‐on fashion.     

Predictors of Success on the Counselor Preparation Comprehensive Examination

This study examined the relationship between 403 counseling graduate students' scores on the Counselor Preparation Comprehensive Examination (CPCE; Center for Credentialing and Education, n.d.) and 3 admissions requirements used as predictor variables: undergraduate grade point average (UGPA), Graduate Record Examinations (GRE) General Test Verbal Reasoning (GRE‐V) score, and GRE General Test Quantitative Reasoning (GRE‐Q) score. Multiple regression analyses revealed that all predictor variables accounted for somewhat limited, yet significant variations in the CPCE‐Total scores (R² = .21). Results indicated that UGPAs, GRE‐V scores, and GRE‐Q scores are valid criteria for determining counseling graduate student success on the CPCE.     

How Does the Freezer Burn Our Food?

ABSTRACT:  Freezer burn is a common problem that significantly affects the color, texture, and flavor of frozen foods. Food science students should be able to clearly explain the causes and consequences of freezer burn. However, it is difficult to find a modern, detailed, accurate, yet concise, explanation of the mechanism and factors influencing the rate of freezer burn, suitable for classroom use. Thus, the purpose of this article is to provide students and instructors alike with such an explanation, replete with visual explanations, including 2 short animations. The animations, in QuickTime format, are available as supporting information and can be downloaded for free educational use.     

Dreamings beyond ‘opportunity’: the collaborative economics of an aboriginal heritage trail

This article presents the Lurujarri Heritage Trail, an Indigenous tourism experience in Northwest Australia as exemplary for a world different from the teleological-minded futurism of neoliberal market economics. Drawing on long-term ethnographic fieldwork undertaken between 2011 and 2015, it first outlines how in 1987 the Trail was established at the very margins of the Australian economy. Through its emphasis on the here and now that is grounded in a collaboration of people and land and acknowledges diverse worldviews and ontological differences, the Trail today offers its participants a means to experience Indigenous culture as different from Western politics and development policies. As a result, its allegedly marginal Dreaming (Bugarrigarra) leads beyond the pursuit of economic opportunity and in doing so enabled the defeat of large-scale industrialisation in the region.     

The “pinpointing effect” vs. the “diffusion effect” of peer influence

Classroom teachers are learning to employ the peer group to “shape up” dissidents. However, singling out a child may produce undesirable side effects such as emotional behavior, resentment, etc. Can the same result be obtained by rewarding the class for ignoring the target behavior of everyone in the room? Twelve subjects were selected from six middle school classes, two from each class. Each entire class was rewarded for increased ignoring of the target behavior (whispering): in the three P (pinpointed) classes, for ignoring the whispering of Designated (target) subjects; in the three D (diffusion) classes, for ignoring whispering by all class members. The results indicate that a peer group can decrease reinforcement of a disruptive behavior and thereby decelerate it in a singled-out child (Pinpointing Effect) or a behavior emitted by any child in class (Diffusion Effect) with equal effectiveness. However, patterns in the data suggest that peers ignored P-Designated subjects most, D subjects next most, and P-Undesignated subjects the least and that this pattern of ignoring was mirrored in the pattern of deceleration of the target behaviors in the three groups. These patterns suggest that the Pinpointing Effect may be stronger than the Diffusion Effect, but further study is needed.     

Parental family stress during pregnancy and cognitive functioning in early childhood: The Generation R Study

We investigated whether parental family stress during pregnancy is associated with cognitive functioning in early childhood in a population-based cohort (n = 3139). Family stress was assessed using the Family Assessment Device at the 20th week of pregnancy and was reported by mothers and fathers. Mothers completed the MacArthur Communicative Development Inventory, measuring children's verbal cognitive functioning, when children were 18 months and they completed the Parent Report of Children's Abilities, measuring nonverbal cognitive functioning, when children were 2 years old. Maternal prenatal family stress was related to children's low word comprehension and poorer nonverbal cognitive development independent of paternal reports. In a subset of 639 children, maternal prenatal family stress was also associated with observational assessments of poor effortful control at age 37 months. Paternal prenatal family stress was only related to poorer nonverbal cognitive development, independent of the mother. When both parents had high levels of prenatal family stress, children displayed particularly poor nonverbal cognitive development. These findings emphasize the significance of parental prenatal family stress for child developmental outcomes.     

Selbstkonzeptförderung im Sportunterricht

Previous intervention studies in school sports designed to test the socialisation hypothesis have tried to raise students’ self-concepts. However, this goal seems to be of questionable functionality: From both an educational and a psychological perspective, it would seem preferable to aim toward making self-concepts as realistic as possible. Underestimating self-concepts might impede performance-related behaviour, whereas overestimating might be dysfunctional, particularly in social interactions. This dichotomy is used to examine which manifestations of the self-concept physical education needs to promote from a psychological perspective. It creates a new perspective for future interventions designed to promote the self-concept in physical education.
