Making and using a cattle backrubber (1993)

A well made, properly placed cattle backrubber will give economical control of horn flies on beef and dairy cattle and will aid in control of face flies. If the backrubber is kept soaked with a recommended insecticide, cattle lice also can be controlled satisfactorily throughout the year

Walk-through trap to control horn flies on cattle (1996)

The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States more than a century ago. Since then, it has become one of the most important fly pests of pasture and range cattle. Field studies conducted in central Missouri during 1986 indicated the trap produced roughly 50 percent control of horn flies when averaged over the season. This level of control was less than that afforded by insecticidal ear tags and some other treatments but maintained horn flies below the injury level of about 200 flies per animal.Revised January 1996 -- Extension website

Invisible Pain: Looking At Women’s Fibromyalgia Disclosure In The Workplace Through The Lens Of Communication Privacy Management Theory

According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (2014), fibromyalgia is identified as an arthritis-related ailment, but it does not damage tissues or cause any form of inflammation. However, individuals with fibromyalgia still experience pain and fatigue. Based on Arnold et al.’s (2008) conclusion that individuals with fibromyalgia experience disrupted relationships, isolation, and loss of or lack of advancement in an occupation, and because women are diagnosed with fibromyalgia more frequently than men, my focus in the study was on the workplace experiences of women with fibromyalgia. Specifically, I was interested in uncovering how these women managed private information about their illness at work, experienced changes in their own and others’ behaviors at work, and perceived being stigmatized by others at work due to their illness. I used Communication Privacy Management (CPM) theory as the guiding framework. I conducted nine in-depth interviews with women afflicted with fibromyalgia who also work. Various themes arose from the interviews related to disclosure, behavioral changes, and stigma. I identify various implications for the study and address limitations and areas for future research

BALLOONS, BREADCRUMBS, AND SPOONS: EMERGING ADULTS’ PRIVACY NEGOTIATION AND MANAGEMENT OF THE (NON)DISCLOSURE OF CHRONIC ILLNESS-RELATED INFORMATION WITH A FRIEND

Emerging adults (EAs) experience many changes throughout this life-stage, characterized by self-focus, identity explorations, instability, in-betweenness, and possibilities of optimism (Arnett, 2014). As EAs transition from home of origin into independence, they may place more reliance on social networks apart from their family of origin (e.g., friends, Rawlins, 2009). Yet, chronically ill EAs may experience complications due to the biographical disruption, or interference of expectations in one’s life (Bury, 1982), particularly given that chronic illness is typically viewed as an elderly-related issue rather than occurring with youth (Kundrat & Nussbaum, 2003). Through transitions in the EA life-stage, EAs with chronic illness may forgo sharing chronic illness-relation information or withhold expressed desire for social support to appear more “normal” to fit in with their peers (Spencer et al., 2019). Thus, I centered the present study in Petronio’s (2002) Communication Privacy Management (CPM) theory to understand how EAs interact and negotiate (non)disclosure of chronic illness-related information with a friend. In the present interpretive and qualitative study, I analyzed and described how EAs interacted and negotiated the process of (non)disclosure of their chronic illness-related information with a friend. Data were 15 in-depth interviews and 15 book cover images to represent the experiences of EAs with chronic illness. In the results, I describe and explain how participants (a) engaged criteria for disclosure and identified the confidants of their disclosure, (b) created boundary rules around their chronic illness-related information, (c) perceived their friends’ role/non-role in chronic illness management, and (d) made sense of their chronic illness-related information management processes. I contribute four theoretical insights regarding CPM: (a) expanding confidant typology, (b) deconstructing disclosure criteria, (c) demonstrating dialectical tensions of private information disclosure, and (d) developing CPM concepts through metaphorical insights. I also offer two main practical implications: (a) creating a resource for EAs with chronic illness and (b) offering a strategy for arts-based therapeutic practice for those working with EAs experiencing biographic disruption.

Planetary nebulae after common-envelope phases initiated by low-mass red giants

It is likely that at least some planetary nebulae are composed of matter which was ejected from a binary star system during common-envelope (CE) evolution. For these planetary nebulae the ionizing component is the hot and luminous remnant of a giant which had its envelope ejected by a companion in the process of spiralling-in to its current short-period orbit. A large fraction of CE phases which end with ejection of the envelope are thought to be initiated by low-mass red giants, giants with inert, degenerate helium cores. We discuss the possible end-of-CE structures of such stars and their subsequent evolution to investigate for which structures planetary nebulae are formed. We assume that a planetary nebula forms if the remnant reaches an effective temperature greater than 30 kK within 10^4 yr of ejecting its envelope. We assume that the composition profile is unchanged during the CE phase so that possible remnant structures are parametrized by the end-of-CE core mass, envelope mass and entropy profile. We find that planetary nebulae are expected in post-CE systems with core masses greater than about 0.3 solar masses if remnants end the CE phase in thermal equilibrium. We show that whether the remnant undergoes a pre-white dwarf plateau phase depends on the prescribed end-of-CE envelope mass. Thus, observing a young post-CE system would constrain the end-of CE envelope mass and post-CE evolution.Comment: Published in MNRAS. 12 pages, 12 figures. Minor changes to match published versio
