This study aims to collect real-time, in situ data from polymer melt extrusion (ME) 3D printing and use only the collected data to non-destructively identify printed parts that contain defects.

A set of sensors was created to collect real-time, in situ data from polymer ME 3D printing. A variance analysis was completed to identify an “acceptable” range for filament diameter on a popular desktop 3D printer. These data were used as the basis of a quality evaluation process to non-destructively identify spatial regions of printed parts in multi-part builds that contain defects.

Anomalous parts were correctly identified non-destructively using only in situ collected data.

This methodology was developed by varying the filament diameter, one of the most common reasons for print failure in ME. Numerous other printing parameters are known to create faults in melt extruded parts, and this methodology can be extended to analyze other parameters.

To the best of the authors’ knowledge, this is the first report of a non-destructive evaluation of 3D-printed part quality using only in situ data in ME. The value is in improving part quality and reliability in ME, thereby reducing 3D printing part errors, plastic waste and the associated cost of time and material.

The purpose of this paper is to provide a case study of the use of technology as a hidden curriculum in a youth leadership program (United Future Leaders-UFL).

A description of the UFL program, including theoretical framework and current use of various technology platforms, provide a backdrop to the hidden curriculum implemented by the programming staff. Both intended and unintended outcomes of the use of technology are discussed in the context of UFL values/themes.

A review of technology use in the UFL program resulted in the categorization of realms of influence (Staff ↔ Student Participants, Staff ↔ Staff, Staff ↔ Parents, Participants ↔ Participants) and five categories of technology use (reminders, communication, sharing of resources, reinforcing learning, increased parental involvement).

Examples of emerging patterns of this hidden curriculum, future directions for technology use within the program, and advice for youth program practitioners are included.

This paper adds to the general discussion of types and purpose of technology use, youth programming, and role of technology use as hidden curriculum.

The purpose of this paper is to examine religious struggles and loss of faith in Christian survivors of Typhoon Haiyan in the Philippines and explore whether any demographic characteristics or experiences during the disaster may have contributed to these responses.

A quantitative survey was used to assess a variety of concepts related to religious responses after disaster. Data were collected using a mix of non-random, convenience sampling methods, with a total sample of 1,929 responses.

Religious struggles, anger toward God, and apostasy after the typhoon was generally low, although a significant minority of respondents expressed feelings of confusion about God and wondered whether God cared about them. Factors that influenced the experience of religious struggles included: education level, socio-economic status, denomination, barangay, loss of loved ones in the disaster, format of post-disaster church fellowship meetings, and the importance of God in their lives prior to the disaster.

Having an appropriate and supportive faith-based environment for those of faith to work through religious struggles is important for supporting emotional and psychological recovery after disaster.

This study explores how disasters can impact individuals’ beliefs and their relationship with God in a non-Western context. This information enhances our understanding on how humanitarian and faith-based organizations can help support emotional and psychological recovery among impacted populations, particularly those who experience struggles.

Currently, the field of education has been seeking innovative strategies to increase the representation of Black male teachers in U.S. classrooms. In this chapter, the author presents a status report of Black male teachers’ path to U.S. K-12 public school classrooms at six critical stages. These stages include the following: (a) Black males with a high school diploma; (b) enrollment in educator preparation programs; (c) educator preparation program completers; (d) educator preparation programs with the highest number of Black male graduates; (e) Black male education degree holders that select teaching as a profession; and (f) the current status of Black male teachers in U.S. K-12 public schools. Based on the data presented in this chapter, recommendations are provided to the field of education to improve their representation for the benefit of all students. Additionally, the critical need for this timely book is discussed.

This study aims to explore the gendered nature of housing insecurity by investigating how gender affects women’s experience moving from transitional to market housing. By describing women’s pathways out of supportive or transitional housing support, the authors show how patriarchal forces in housing policies and practices affect women’s efforts to find secure housing. The authors argue that gender-neutral approaches to housing will fail to meet women’s needs.

This study explores the narratives from women accessing support services in Halifax, Canada. The first author conducted deep narrative interviews with women seeking to move from transition to market housing.

This research sheds light on the effects of gendered barriers to safe, suitable and affordable housing; how women’s experiences and expectations are shaped by these barriers; and, how housing-based supports must address the uniquely gendered experiences women face as they access market housing. In addition, this research reveals the importance of gender-responsive services that empower women facing a sexist housing market.

Little research has explored questions related to gender and housing among those seeking to move from transitional to marker housing, and existing research focuses on women’s housing insecurity as it relates to domestic violence. The sample of women included those having housing insecurity for a variety of reasons, including substance use and young motherhood.

The author addresses the world of Instagram influencers but offers a very different perspective by focusing on the gendering of claims to authenticity on social media. The author observes how high-profile male and female Czech influencers are required to navigate an authenticity bind (Duffy & Hund, 2019) through two key strategies: the opinion-leader strategy and the community-building strategy. Men rely predominantly on the opinion-leader strategy while women position themselves as community builders. By focusing on the communicative strategies of the influencers, the author offers an analysis of authenticity as performative process, rather than a static concept, that gets negotiated in everyday interactions between influencers and their followers.
