Cell freezing and the biology of inexorability: on cryoprotectants and chemical time
Authors: Landecker Hannah 
Published: July 2024

AbstractWhat can’t freezing hold still? This article surveys the history of substances used to protect cells and organisms from freezing damage, known as cryoprotectants. Dimethyl sulfoxide (DMSO) has since 1959 been the most widely used of these agents in cryopreservation. Here, its evolution from pulp and paper waste byproduct to wonder drug to all-but-invisible routine element of freezing protocols is used to trace the direct arc from protection to toxicity in theories of how and why cryoprotectants work, from the 1960s to today. The power of these agents to simultaneously protect and degrade is shown to reside in manipulation of chemical time via hydrogen bonding and electron exchange, thereby reframing freezing as a highly active and transformational process. Countering long-held assumptions about cryopreservation as an operation of stasis after which the thawed entity is the same as it was before, this article details recent demonstrations of effects of cryoprotectant exposure that are nonlethal but nonetheless profoundly impactful within scientific and therapeutic practices that depend on freezing infrastructures. Understanding the operationalization of chemical time in the case of cryoprotectants is broadly relevant to other modern technologies dedicated to shifting how material things exist and persist in human historical time.
Differentiated secularism: discourse shaping of immigrants from different religious backgrounds in the French media
Authors: Song Wenlong , Pang Bo , Wang Zihan , Xu Yilang , Liu Zetong , Tan Murong 
Published: July 2024

AbstractThis paper examines the mechanisms of differentiated discursive disciplining for immigrants of different religious backgrounds in the French media. Based on a sample of 120 articles on immigration in the French mainstream media, textual analyses and comparisons were conducted. Results show that influenced by religious factors, the French media use secularism as a tool to portray completely different images of immigrants through different discursive logics. Muslim immigrants present a paradoxically biased negative image in the French media discourse as a collection of invaders and the disciplined. In contrast, the media image of Ukrainian immigrants of Orthodox Christian background is positive on the whole, with a certain degree of deliberateness in the details of its construction. The difference in the symbolic characterization between Catholicism and Islam enables the exclusionary media discourse against Muslim immigrants. The paper also discusses French media discourse flaws and policy dilemmas. The logic of French media discourse is paradoxical in its inability to maintain an intact secularist identification and to effectively influence political issues to the detriment of promoting immigrant integration.
Elusive referentiality and allusive reference in Indonesian conversation
Authors: Ewing Michael C. 
Published: July 2024

Abstract
This chapter examines referential practices in a corpus of colloquial Indonesian conversation and attempts
to address the question: “Does referentiality matter to speakers?” I take referentiality to be a multi-dimensional phenomenon
involving (at least) whether referents are construed as general or particular and whether they are tracked through discourse.
Through close examination of excerpts from conversational interaction, I show that there is often a blurring between the
general and the particular, that referents are often indeterminate, and that referentiality as a discrete and classifiable
linguistic property often does not seem to be relevant to participants in ongoing interaction. In this sense, referentiality
does not always appear to matter to speakers. At the same time, referential practices do appear to be exploitable by speakers
as resources for social action. Specifically, I show that a shift in referential practices regularly coincides with a shift in
alignment, understood in terms of footing. These may involve shifts between generalising and exemplifying or moving from
narratorial to quoted speech. To the extent that shifts in referentiality coincide with shifts in footing, then it can be said
that referentiality does matter to speakers.
The (non)referentiality of the word raha ‘money’ in Finnish conversation
Authors: Laury Ritva 
Published: July 2024

Abstract
This chapter concerns the use of the word raha ‘money’ in Finnish everyday conversation.
The main findings are that raha is most often used non-referentially in singular form in predications where
only the category of money is at issue. When the word is used to create referential mentions of some specific money with
continuity of identity, a plural form is used. The study shows that the singular-plural distinction is a manipulable resource
exploited by participants in conversation for interactional purposes to create stance and to accomplish actions.
Young children’s experience of referentiality and nonreferentiality in dialogue
Authors: Le Mené Marine , Salazar Orvig Anne , da Silva-Genest Christine , Marcos Haydée 
Published: July 2024

Abstract
This chapter focuses on young children’s experience of referential and nonreferential uses of noun phrases
(NPs) in everyday dialogues. Our study of a corpus of interactions between adults and children aged 1;10 to 2;6 showed that
the indeterminacy and instability that might characterise children’s uses can also be found in adults’ discourse. Not only are
(non)referential values co-constructed, but children are also not exposed to clear-cut contrasts between the uses or values of
NPs. On the contrary, both in the adults’ discourse and in the way adults react to children’s utterances, they seem to
experience the fact that noun phrases potentially present various facets, which can be successively or simultaneously
activated in dialogue.
(Non)referentiality of silent reference in Japanese conversation
Authors: Matsumoto Yoshiko 
Published: July 2024

Abstract
Japanese speakers carry out successful conversations in which arguments and adjuncts of predicates are not
expressed. I call such unmentioned members of an event or state that can be inferred
INFERABLES
.
Inferables present a range of interpretations from specific to more general and indeterminate. This chapter explores
principled explanations for this phenomenon in Japanese, which allows a variety of disparate interpretations. The discussions
find that frame semantics, a semantic theory that provides an envisionment of a described event with the attendant roles, can
offer an explanation. Hearers and speakers
TRUST
each other that some plausible entities
(inferables) instantiate the unmentioned elements. When clarification is needed, they seek to

The indeterminacy and fluidity of reference in everyday conversation
Authors: Ono Tsuyoshi , Thompson Sandra A. 
Published: July 2024

Abstract
We focus on (a) the indeterminacy of reference, i.e., noun phrases which are described as having a ‘given’,
‘old’ or ‘definite’ referent, where that referent is unspecified; (b) the ways in which speakers shift reference between
categorial and specific designations. The data reveal that talk displaying indeterminate and shifting reference is
consistently accepted without being challenged. These facts show that reference can only be understood by considering how
speakers refer locally, in the unfolding of social action, and that referential common ground is generally established despite
the referential indeterminacy and fluidity. We thus promote the view that reference is a deeply social phenomenon, an emergent
set of practices that is used and negotiated by people in real time.
Manipulating referentiality and creating phaticness
Authors: Suzuki Ryoko 
Published: July 2024

Abstract
The focus of this study is the creation of novel ad hoc expressions from the perspective of referentiality.
Through the close analysis of three cases from video-recorded conversations in Japanese, we find that speakers create novel
NPs by manipulating referentiality and embodiment, and achieve social bonding by humorously and intensely repeating those
expressions. Even an onomatopoeic adverbial can be turned into a novel ad hoc NP. After creating and reinforcing those novel
NPs with exaggerated delivery, speakers drop the exaggerated delivery, pronouncing the novel NPs as if they are regular
NPs.
An interactional approach to generic second person expressions in Mandarin conversation
Authors: Tao Hongyin 
Published: July 2024

Abstract
This chapter tackles the hitherto under-explored question of when and why conversationalists deploy second
person generic expressions that feature a general and vague referential scope. I show that the conversational contexts in
which they appear are usually characterized most prominently by their relatively complex and/or controversial subject matters,
participants’ incongruent stances, and/or opposing positions to be contested. These contexts and their associated
interactional demands are argued to give rise to the patterning of clustering (multiplicity of instances in adjacent units),
limited generality (as good-enough-yet-not-too-broad general statements), and primary (or attempted primary) speakership. In
general, second person generic statements can be seen as a special and powerful rhetorical device designed for marked
interactional occasions.
The McCusker Subjective Cognitive Impairment Inventory (McSCI): a novel measure of perceived cognitive decline
Authors: Sohrabi Hamid R , Gavett Brandon E , Weinborn Michael , Speelman Craig P , Bucks Romola S , Martins Ralph N 
Published: July 2024

Abstract

Background
Subjective cognitive decline (SCD), i.e. self/other-reported concerns on one’s cognitive functioning without objective evidence of significant decline, is an indicator of dementia risk. There is little consensus on reliability and validity of the available SCD measures. Therefore, introducing a novel and psychometrically sound measure of SCD is timely.

Objective
The psychometric properties of a new SCD measure, the McCusker Subjective Cognitive Impairment Inventory–Self-Report (McSCI-S), are reported.

Methods
Through review of previously published measures as well as our clinical and research data on people with SCD, we developed a 46-item self-report questionnaire to assess concerns on six cognitive domains, namely, memory, language, orientation, attention and concentration, visuoconstruction abilities and executive function. The McSCI-S was examined in a cohort of 526 participants using factor analysis, item response theory analysis and receiver operating characteristic (ROC) curve.

Results
A unidimensional model provided acceptable fit (CFI = 0.94, TLI = 0.94, RMSEA [90% CI] = 0.052 [.049, 0.055], WRMR = 1.45). The McSCI-S internal consistency was excellent (.96). A cut-off score of ≥24 is proposed to identify participants with SCDs. Higher McSCI-S scores were associated with poorer general cognition, episodic verbal memory, executive function and greater memory complaints and depressive scores (P &lt; .001), controlling for age, sex and education.

Conclusions
Excellent reliability and construct validity suggest the McSCI-S estimates SCDs with acceptable accuracy while capturing self-reported concerns for various cognitive domains. The psychometric analysis indicated that this measure can be used in cohort studies as well as on individual, clinical settings to assess SCDs.
A - 01 Differences in Recovery among Acutely Injured Pediatric Concussion Patients with and without Cervicogenic Symptoms
Authors: Mathew A S , Datoc A E , Hartland L C , Roberts K , Sexton J A , Abt J P 
Published: July 2024

Abstract

Purpose
While previous research has demonstrated that cervicogenic symptoms may affect initial symptom burden, mixed findings exist regarding its effects on recovery time. The purpose of this study was to compare acutely injured pediatric sports-related concussion (SRC) patients, with and without cervicogenic symptoms, in terms of symptom burden, vestibular ocular motor components, and recovery time.

Method
Data were gathered from patients aged 8–18 years, evaluated within seven days since injury, and with and without cervicogenic symptoms. Demographic data were examined based on age, gender, race, and ethnicity. The neck and suboccipital regions were assessed for range of motion, tenderness, and spasm. Overall VOMS change score was calculated using Elbin et al., 2022 criteria. Symptom burden was assessed using Post-Concussion Symptom Scale (PCSS) scores. Analysis of variance and regression analyses were conducted.

Results
Of the 2018 pediatric patients diagnosed with SRC, 552 had cervicogenic symptoms. Those with cervicogenic symptoms had significantly greater PCSS scores (MCervical = 35.50¬ ± 23.50, MNoCervical = 21.70¬ ± 20.80), overall VOMS change scores (MCervical = 17.90¬ ± 17.40, MNoCervical = 12.00¬ ± 15.30) and longer recovery time (MCervical = 22.90¬ ± 13.90, MNoCervical = 20.0¬ ± 14.60) compared to those without cervicogenic symptoms (p &lt; 0.001). The model revealed a significant interaction effect between cervicogenic symptoms, VOMS, and PCSS (R2 = 0.128, F(3, 1898) = 93.49, p &lt; 0.001).

Conclusions
Our results showed that pediatric patients with cervicogenic symptoms not only demonstrate greater concussion symptom burden as demonstrated by PCSS and VOMS, but also take longer to recover than those without cervicogenic concerns. The results underscore the need for early detection and treatment of cervicogenic issues alongside standard concussion management to expedite recovery.
A - 02 Time to Physical Therapy in Pediatric Concussion Patients Influences Recovery Outcomes
Authors: Mathew A S , Datoc A E , Choi D M , Tak C R , Abt J P 
Published: July 2024

Abstract

Purpose
Physical therapy (PT) is an effective treatment approach for sports-related concussion (SRC) for patients with high symptom reporting, cervicogenic dysfunction, or vestibular/oculomotor deficits. The purpose of this study was to compare clinical indicators of concussion patients referred to PT who had protracted recovery (PR) and normal recovery (NR).

Method
108 patients (28 NR, 80 PR) were evaluated at a pediatric specialty concussion clinic between April 2021 and December 2023. Patients were between 12–18 years, diagnosed with SRC, evaluated for concussion within one week of injury, referred to PT, completed more than one PT session, and received medical clearance at follow-up appointment. Patients were divided based on PR (&gt;21 days) and NR (‚â§ 21 days) and compared via days since injury to PT, days from concussion evaluation to PT, and number of PT sessions.

Results
Compared to the NR group, the PR group had greater days since injury to PT (MdnPR = 12.00; MdnNR = 3.00; U = 322.00,p &lt; 0.001), days from concussion evaluation to PT (MdnPR = 6.00; MdnNR = 0.50; U = 517.50, p &lt; 0.001), and engaged in a higher number of PT sessions than the NR group (MdnPR = 4.00; MdnNR = 3.00; U = 787.50, p = 0.02). The PR group also had a greater number of recovery days from PT evaluation compared to the NR group (MdnPR = 27.00; MdnNR = 10.00; U = 108.00, p &lt; 0.001).

Conclusions
Previous studies have also shown that time to concussion evaluation is an important prognostic indicator of recovery. Correspondingly, prompt referral to PT should be promoted by providers, athletic trainers, and parents for patients who require higher escalation of concussion care to improve recovery outcomes.
A - 03 Outcomes of Standardized Care on Recovery for Repeated Concussion
Authors: Choi D M , Mathew A S , Roberts J K , Abt J P 
Published: July 2024

Abstract

Purpose
Recovery outcomes from consecutive concussions require greater empirical support. The purpose of this study was to compare recovery outcomes of patients who sustained repeated sport-related concussions (SRC) and received care at the same specialty clinic.

Method
Data were extracted from 148 patients, aged 12–18, diagnosed and evaluated in a specialty clinic for two consecutive SRCs. Comparisons between initial visits for first and second concussions included demographics, medical history, assessment scores, days since injury (DSI), and injury recovery days using paired sample t-tests. A linear regression model was built with relevant variables (age, gender, comorbidities, DSI, VOMS, PCSS) to predict recovery days for first SRC. Another model was constructed with significant variables to predict recovery days for second SRC.

Results
Individuals were evaluated within approximately one year from their first SRC (MAge = 14.61¬ ± 1.47) to their second (MAge = 15.44¬ ± 1.37, MeanDifference = 0.83, p &lt; 0.001). There were no significant differences between other variables (p &gt; 0.05). PCSS and overall VOMS change scores predicted recovery days for first SRC (R2 = 0.30, p &lt; 0.001). However, the new model for second SRC accounted for much less of the variance in recovery days (R2 = 0.11).

Conclusions
Our results show patients do not experience a worse outcome from subsequent concussion (PCSS, VOMS, DSI, recovery days). However, clinical outcomes from patients’first SRC do not seem to implicate recovery outcomes for their second SRC. Despite controlling for commonly researched predictors of recovery, our findings highlight the heterogeneous nature of SRC for the same individual receiving standardized care. Additional research is needed to examine further intraindividual differences in those who sustain consecutive SRCs.

Published: July 2024

Abstract

Purpose
Little has been done to investigate the impact of cheerleading season progression on recovery trajectories of sports-related concussions (SRC). The purpose of this study was to assess the impact of season progression on concussion recovery in All Star cheerleaders.

Method
Female All Star cheerleaders (n = 52) aged 8–18 (13.9.0¬ ± 2.5 years) were evaluated in a specialty concussion clinic for SRC during the 2020–2023 seasons. Cheerleaders were sorted into groups based on when their injury occurred (T1 = tryout/practice portion of season, T2 = beginning of competition season, T3 = end of season/coveted competitions). Mann–Whitney U Tests were used to evaluate differences between groups.

Results
Most All Star cheerleaders were evaluated for SRC during T2 (n = 32) compared to T1 (n = 12) and T3 (n = 8). Cheerleaders injured during T2 reported significantly lower PCSS scores (M = 21.0, IQR = 15.0–37.0) compared to T1 (M = 52.5, IQR = 27.5–60.8) and T3 (M = 46.9, IQR = 34.0–90.0), p = 0.01. There were no significant differences in days since injury (DSI; T1 M = 5.67, SD = 7.84; T2 M = 6.13, SD = 8.64; T3 M = 3.50, SD = 2.67) and evaluation of overall recovery time across groups (T1 M = 20.92, SD = 10.19; T2 M = 24.25, SD = 17.85; T3 M = 16.38, SD = 13.89; p &gt; 0.05).

Conclusions
Overall, cheerleaders injured during the beginning of competition season had the lowest PCSS scores upon evaluation, which may be due to presenting to clinic further from their injury. Though not significant, All Star cheerleaders were evaluated sooner during the coveted competitions portion of the season. Despite the small sample size, the pattern of results suggests that greater incentive and pressure to participate in coveted competitions may lead to quicker recovery times.
A - 05 The Relationship between Child Opportunity and Self-Efficacy Following Pediatric Concussion
Authors: Johnson H M , Guerin J M , Gioia G A , Vaughan C G 
Published: July 2024

Abstract

Purpose
An individual’s confidence in their ability to facilitate their concussion recovery (i.e., self-efficacy [SE]) is important for outcomes. Self-efficacy may be influenced by early childhood experiences and access to environmental resources. This study explores the relationship between neighborhood opportunity and self-efficacy following pediatric concussion.

Method
Participants completed a 17-item self-efficacy measure (PACE-SE) during an initial clinic visit. The Child Opportunity Index (COI) was obtained based on each child’s home address. A stepwise linear regression was employed to examine the relationship between COI and PACE-SE accounting for symptom burden, days since injury, and sex.

Results
431 participants aged 13–18 (M = 15.1+/−1.6; 58% female) were seen within three months of concussion (M days since injury = 19.2+/−16.2) at a specialty clinic. The majority were injured playing sports (67%). Lower PACE-SE score was associated with female sex (r = 0.180; p &lt; 0.001), higher symptom burden (r = −0.493, p &lt; 0.001), and more days from injury (r = −0.132; p = 0.003). There was a small but significant relationship between COI and PACE-SE, after accounting for covariates (R2 = 0.008, p = 0.033). Stepwise regressions showed associations between COI and the PACE-SE subdomains Managing my Stress (MMS; R2 = 0.008, p = 0.031), Seeking Adult Assistance (SAA; R2 = 0.015, p = 0.008), and Maintaining a Positive Outlook (MPO; R2 = 0.009, p = 0.022), but not Managing my Activity (MMA). SAA and COI were significantly associated in males (p &lt; 0.05), while MPO and COI were significant in females (p = 0.001, &lt;0.05).

Conclusions
The results suggest that lower neighborhood opportunity is associated with lower overall self-efficacy in facilitating one’s recovery after concussion. Specific aspects of self-efficacy may be uniquely impacted, such as seeking adult assistance.
A - 06 Examining Consumer Feedback on the 2023 International Conference Consensus Statement on Concussion In Sport
Authors: Magill R , Vaughan C , Echemendia R , Kringler W , Bailey C 
Published: July 2024

Abstract

Purpose
The 6th International Conference on Concussion in Sport distilled its main outcomes and recommendations into a consensus statement, which will likely have significant influence on the evaluation and management of sport-concussion. This abstract examines opinions on the statement among healthcare providers, including those who contributed to the conference and those who did not.

Method
A survey was designed with minor concussion-specific modifications using the Appraisal of Guidelines Research and Evaluation 2nd edition (AGREE II) framework. This framework features 6 domains evaluated on a 7-point Likert scale - Scope and Purpose, Stakeholder Involvement, Rigour of Development, Clarity of Presentation, Applicability, and Editorial Independence. 72 participants completed the survey, including neuropsychologists (29.2%), physicians (31.9%), and athletic trainers (31.9%). The majority were not involved in the statement (71.8%).

Results
The Scope and Purpose domain was most favorably endorsed (80.3%), followed by Rigour of Development (76%), Clarity of Presentation (74%), Editorial Independence (72.1%) and Stakeholder Involvement (70.7%). The Applicability domain was least favorably endorsed (69.5%). The majority of domain ratings did not differ significantly among healthcare providers, except for the Stakeholder Involvement and Applicability domains were rated higher by athletic trainers than physicians (p = 0.011, p = 0.007, respectively). No differences in opinions across the six domains were found between those who did and did not contribute to the statement.

Conclusions
Overall, the consensus statement was rated favorably by survey participants. Lower ratings in the Applicability domain suggest an area for improvement when developing future consensus statements.
