Participation of non-dominant students in argumentation in the mathematics classroom

This article focuses on argumentation in mathematics classrooms in two different geographic contexts, the US and New Zealand. Drawing on data from a case with immigrant students (Pāsifika) in NZ and a case with Mexican American students in the US, we argue for the need to study the concept of argumentation through a cultural and language lens. Our analysis across the two cases points to common features that supported students’ engagement in argumentation. Building relationships and encouraging and supporting students to be themselves are seen as resources for argumentation. The similarities across two very different contexts are striking. As we think of how to develop environments that support non-dominant students’ participation in mathematical argumentation, we may want to learn from and build on students’ cultural ways of being.     

Managing Children’s Friendships Through Interparental Relationships: Roles of Ethnicity and Friendship Context

Twenty African American and European American mothers of fourth‐grade students reflected on strategies for managing children’s friendships maintained across a variety of contexts. Ethnicity differentially located families within specific social contexts that yielded children’s friendships, then informed social processes as they unfolded within these contexts. Maternal knowledge concerning children’s friendships developed as a function of the types of relationships formed among parents encountered within different settings. Findings suggest that interparental relationships represent a key source of information about children’s friendships. Yet, maternal opportunities to establish such relationships differ on the basis of both ethnicity and the nature of contexts in which children’s friendships are maintained.     

Rural Migration,Rapid Growth,and Fear of Crime*

Abstract Although much research on rural “boomtowns” explores differences between rapid‐growth communities and more stable communities, it is logical to consider that residents within rural boomtowns experience community transitions in different ways. We examine a specific outcome, fear of crime, across three categories of community residents with different migration histories: lifetime residents, migrants who joined the boomtown community during its period of rapid growth, and post‐boom period migrants. This perspective is particularly interesting, given the likelihood that these three different categories of residents have had substantially different community experiences. Making use of survey data from two intermountain West communities that represent resource‐dependent transitions during the 1970s and 1980s (Evanston, Wyoming and Delta, Utah), we find that boom migrants express greater fear of crime than longer‐term residents or post‐boom migrants. The findings suggest that the longer‐term decline in fear of crime in “post‐boom” periods is not equal among residents.     

Population Growth in High‐Amenity Rural Areas: Does it Bring Socioeconomic Benefits for Long‐Term Residents?*

OBJECTIVE: A widely noted concern with amenity-driven rural population growth is its potential to yield only low-wage service-sector employment for long-term residents, while raising local costs of living. This research examines change in socioeconomic status during the 1990s for long-term residents of high-amenity, high-growth rural counties in the United States. METHODS: Using longitudinal data from the Panel Study of Income Dynamics, in combination with county-level information, we estimate growth-curve models to examine the extent to which the socioeconomic status of long-term residents is associated with amenity-related in-migration. RESULTS: We find that, on average, residents in high-growth, amenity-rich rural areas have higher income growth over time and higher levels of initial occupational prestige compared to those from other rural areas, but that socioeconomic gains are primarily for individuals with low baseline prestige. CONCLUSIONS: The socioeconomic gains made by long-term residents of high-growth, amenity-rich rural areas associated with net in-migration may be limited to individuals with low initial prestige and growth may be due to low-skill service-sector jobs.     

Life Balance and Work Addiction Among African Americans

A dearth of counseling literature examines the experiences of people of color, including African American women and men, in relation to work–life balance. The authors, therefore, investigated the association between life‐balance domains and work addiction for African Americans. A multiple regression analysis of 115 African American participants (47 men, 68 women) indicated a significant relationship between life‐balance domains and work addiction. In particular, community support was an important indicator of decreased work addiction. Career counselors and mental health counselors need to develop an understanding of how extended familial and social networks assist African American clients in effectively managing work–life balance.     

Fast Computation by Block Permanents of Cumulative Distribution Functions of Order Statistics from Several Populations

The joint cumulative distribution function for order statistics arising from several different populations is given in terms of the distribution functions of the populations. The computational cost of our formula in the case of two populations is still exponential in the worst case, but it is a dramatic improvement compared to the general formula by Bapat and Beg. In the case when only the joint distribution function of a subset of the order statistics of fixed size is needed, the complexity is polynomial, for the case of two populations.     

Nursing staff's attitudes toward seclusion & restraint

1. Staff preferred to treat patients as they themselves wanted to be treated. 2. More than one third of respondents did not view seclusion and restraint use as a time for a therapeutic intervention. 3. If staff are practicing from their belief patterns, they will choose interventions to avoid use of seclusion and restraint. 4. The majority of respondents preferred using medication to treat out-of-control behavior because they considered it less restrictive.
