Accounting for sustainability: episteme change and ontological plurality

Recent research reveals accounting for sustainable development to be both problematic and essential. This paper considers that the problems arising may be intrinsic to the concepts and structures of Modern accounting and that their resolution lies ultimately in the development of the consequences of a new possibility of knowledge or episteme. After a brief presentation of the nature and historic impacts of episteme change, this paper explores the epistemic origins of Modern accounting. Evidence for a new, other than Modern, episteme is then presented and its consequences for accounting for sustainable accounting are explored. Significant evidence in this regard is the work of Bruno Latour from Actor-Network Theory to the plurality of ontologies. Refs 93

Leading with Passion – What It Means, Why It Matters

This ability to care, or to lead with passion, has increasingly been identified as a quality of today’s leaders and has been cited as an essential condition precedent for successful organizations (Duckworth, 2018; Love, 2012; Collins, 2001). Understanding the role of passion in in building strong relationships has practical benefits for both leaders and followers. The focus of this paper was to identify key elements of passion that contribute to effective leadership and to explain why leading with passion is so important in today’s highly competitive business climate. The authors provided eight elements or qualities that are critical to leading with passion, five guiding principles to assist today’s leaders and managers for becoming caring and compassionate leaders, and concluded with a challenge to those who wish to lead effectively to honor the duties that leadership demands

Assessment of distress, unmet needs, and receipt of care plans among cancer survivors in Georgia

Background: Cancer survivors have distinctive healthcare needs. The Survivorship Working Group of the Georgia Cancer Control Consortium conducted an assessment to understand the physical, psychological, practical, and spiritual needs of adult cancer survivors; patient perceptions regarding patient-provider communications; and their perceived need for services. Methods: In 2014, a convenience sample of Georgia cancer survivors completed a paper or online survey about the presence of and distress associated with unmet physical, emotional, spiritual, and practical needs, and receipt of assistance in those areas. They were also asked about receipt of cancer treatment and survivorship care plans. Results: Survivors were primarily female, married, White, and within 5 years of treatment. High proportions reported moderate to extreme levels of distress with depression (32.7%), anxiety (32.1%), stress (30.2%), and fear of recurrence (28.2%). Many reported no receipt of assistance in emotional needs such as changing relationships and defining a new normal and physical needs such as intimacy and body image. Fewer than half (48%) reported having received a cancer treatment summary from their physician and only 37% received a survivorship care plan. Of those who received either, 98% reported that the information was helpful. Conclusions: Cancer survivors in Georgia who responded to the survey had unmet needs, especially related to physical and mental health. More widespread adoption of guidelines of the Commission on Cancer, including the use of distress screening tools, would assist providers in addressing identified needs directly or through referrals. A limitation is that the racial and ethnic minority participation of 20.1% is insufficient to generalize results to all cancer survivors in Georgia. Subsequent surveys would benefit from targeted approaches to reach diverse and underserved survivors

The mediating effect of social network identity management on the relationship between personality traits and social media addiction among pre-service teachers

Background: The use of social media has become an important part individuals’ daily lives and is used in many daily life activities, such as social interaction, education, and shopping. However, with the increase in the use of social media, a minority of individuals can experience problematic use (and in extreme cases, ‘social media addiction’). The purpose of the present study was to examine the effect of personality traits on social media addiction and the mediating role of social network identity management in this relationship among preservice teachers. Methods: The data were collected from 275 pre-service teachers at a university in Türkiye. The survey included the Big Five Inventory-10 (BFI-10), the Social Network Identity Management Scale, the Bergen Social Media Addiction Scale, and a personal information form. Results: The findings of the study indicated that there was a relationship between personality traits, social network identity management, and social media addiction. Specifically, neuroticism was positively associated with social media addiction, whereas extraversion, agreeableness and conscientiousness were negatively associated. The results also indicated that social network identity management mediated the effect of personality traits on social media addiction. Conclusion: Given that the present investigation was only a preliminary study, further research is needed to examine whether social network identity management is an important determinant in understanding the relationship between personality traits and social media addiction

Early pericalcarine atrophy in acute optic neuritis is associated with conversion to multiple sclerosis

Background: Previous work showed that pericalcarine cortical volume loss is evident early after presentation with acute clinically isolated optic neuritis (ON). The aims of this study were: (1) to determine whether pericalcarine atrophy in patients with ON is associated with conversion to multiple sclerosis (MS); (2) to investigate whether regional atrophy preferentially affects pericalcarine cortex; and (3) to investigate potential causes of early pericalcarine atrophy using MRI. / Methods: 28 patients with acute ON and 10 controls underwent structural MRI (brain and optic nerves) and were followed-up over 12 months. Associations between the development of MS, optic nerve, optic radiation and pericalcarine cortical damage measures were investigated using multiple linear regression models. Regional cortical volumetric differences between patients and controls were calculated using t tests. / Results: The development of MS at 12 months was associated with greater whole brain and optic radiation lesion loads, shorter acute optic nerve lesions and smaller pericalcarine cortical volume at baseline. Regional atrophy was not evident in other sampled cortical regions. Pericalcarine atrophy was not directly associated with whole brain lesion load, optic radiation measures or optic nerve lesion length. However, the association between pericalcarine atrophy and MS was not independent of these parameters. / Conclusions: Reduced pericalcarine cortical volumes in patients with early clinically isolated ON were associated with the development of MS but volumes of other cortical regions were not. Hence pericalcarine cortical regions appear particularly susceptible to early damage. These findings could be explained by a combination of pathological effects to visual grey and white matter in patients with ON

Structure, magnetism, and magnetocaloric properties of MnFeP1−xSix compounds

MnFeP1-xSix compounds with x=0.10,0.20,0.24,0.28,...,0.80,1 were prepared by high-energy ball milling and solid-state reaction. The structural, magnetic, and magnetocaloric properties are investigated as a function of temperature and magnetic field. X-ray diffraction studies show that the samples in the range from x=0.28 to 0.64 adopt the hexagonal Fe2P-type structure with a small amount of second phase which increases with increasing Si content. The samples with lower Si content show the orthorhombic Co2P-type structure. Magnetic measurements show that the paramagnetic-ferromagnetic transition temperatures range from 214 to 377 K. Of much importance is the fact that these compounds do not contain any toxic components and exhibit excellent magnetocaloric properties

DXA assessment

Accurate assessment of body composition is an important issue among athletes. Different methodologies generate controversial results, leading to a deep uncertainty on individual exercise prescriptions. Thus, this study aims to identify the differences between field methods, such as bioelectrical impedance (BIA) and skinfold assessment, with a clinical method, highly accurate, dual-energy X-ray absorptiometry (DXA), among elite young football players. Thirty-eight male football players with a mean (sd) age of 16.7 (0.87) years, involved in the Portuguese national competition of U16 (n = 13) and U19 (n = 25), were evaluated and objective measures of body composition, muscle strength and football skills were collected by trained specialists. Body composition was assessed using BIA (Tanita BC-418, Tanita Corp., Tokyo, Japan), in agreement with all the evaluation premises. Additionally, all athletes were evaluated using the clinical method DXA (Hologic Inc., Waltham, MA, USA). Among the U19 athletes, three skinfold sites (SKF) were assessed: chest, abdomin and thigh. The Spearman correlation coefficients and the mean difference between methods were calculated. The agreement between both methods was analyzed using Bland-Altman plots. Among the evaluated athletes, lower mean values of body fat % were found using BIA as a method of body composition assessment compared with DXA (12.05 vs. 15.58 for U16; 11.97 vs. 14.16 for U19). Despite the moderate correlation between methods (r = 0.33) to estimate the percentage of total fat, the median of the difference (DXA vs. BIA) was relevant in clinical terms, with 2.90% and 1.47% for U16 and U19 athletes, respectively. Stronger correlations were found between the sum of the SKF and DXA fat estimation (r = 0.68). The Bland-Altman plots showed a clear underestimation in the evaluations using the BIA, namely among athletes with better body composition profiles (8%?12% of fat). Using BIA, an underestimation of body fat assessment was observed among 94.5% of the athletes with less than 12% body fat mass. Among the evaluated athletes, fat mass was underestimated at a median value of 2.21% using BIA in comparison with DXA. The sum of the SKF showed a stronger correlation with the reference method (DXA) (r = 0.68) than BIA.D915-7373-ED16 | Cesar LeaoN/

Data-driven efficient score tests for deconvolution problems

We consider testing statistical hypotheses about densities of signals in deconvolution models. A new approach to this problem is proposed. We constructed score tests for the deconvolution with the known noise density and efficient score tests for the case of unknown density. The tests are incorporated with model selection rules to choose reasonable model dimensions automatically by the data. Consistency of the tests is proved

Relationship between power condition, agility, and speed performance among young roller hockey elite players

Purpose. The study was intended to describe the correlations between speed performance (11 m, 22 m, and 33 m) and agility test in skates with determinants of muscular power (squat jump, countermovement jump) in young Portuguese roller hockey athletes involved in a regional selection. Methods. A cross-sectional study was conducted among 10 male roller hockey players with mean (? SD) age of 14.20 (0.57) years, involved in the Portuguese national competition of under-15, making part of the final Oporto district selection of players to participate in inter-regional selections competition. Their mean (? SD) weight, height, body mass index, and sum of the skinfolds were 58.62 (8.78) kg, 165.72 (8.45) cm, 21.26 (1.52) kg/m2, 51.80 (14.91) mm, respectively. Furthermore, it strength was measured with squat jump and countermovement jump; sprinting time at 11 m, 22 m, and 33 m was determined, as well as time in an agility t-test, conducted in roller skating. Spearman correlation coefficients were calculated to test the associations. Results. Significant inverse correlations between vertical jumps, a practical method of power training monitoring, and linear velocity in skating (countermovement jump vs. speed, ?0.78) were found. Despite the increasing complexity of the agility test, a moderate inverse correlation with strength was observed, too (?0.48). Conclusions. Lower limbs explosive strength turned out a strong predictor of skating linear speed and agility among young roller hockey players, providing a simple evaluation tool of important determinants of performance.D915-7373-ED16 | Cesar LeaoN/
