Facial action units, activity and time spent with dam are effective measures of pain in response to mulesing of Merino lambs
No full textRepeatable measures of pain in ruminants following husbandry procedures are required to validate responses to pain relief. This study tested the hypotheses that facial action units, activity and time spent with dam can be used to assess the efficacy of pain relief in lambs following mulesing. Merino lambs (n = 120) were allocated to one of six treatments implemented at mulesing: (1) lambs that were not mulesed or lambs that were mulesed and administered (2) no pain relief, (3) meloxicam 15 min before mulesing, (4) Tri‐Solfen®, (5) a combination of meloxicam 15 min before mulesing and Tri‐Solfen after mulesing and (6) meloxicam at mulesing. Facial action units detected a difference in pain between mulesed and non‐mulesed lambs at 1 and 5 h post‐mulesing (P = 0.005 and <0.001) but not at 26 h post‐mulesing. Lambs that were not mulesed were more active and spent more time with their dams than mulesed lambs (P < 0.001). No differences were observed between lambs that were mulesed with or without pain relief. Therefore, facial action units, activity of the lamb and time spent with dam can detect pain in response to mulesing in Merino lambs but cannot detect any changes associated with pain relief
Service co-creation on social media: Varieties and measures among nonprofit organizations
No full textPurpose
Little is known about the variations in service co-creation on social media, despite the resource integrating capabilities and co-creator roles afforded by these platforms. The gap is even more troubling in the nonprofit sector, where leveraging public interaction on social media is prevalent and vital to charitable and philanthropic endeavors. Arguably, such interaction is embedded in resource integrating activities leading to nonprofit service co-creation. This paper reports the forms, dimensions or service co-creation measures enabled by social media use in the nonprofits' sector.
Design/methodology/approach
The authors conducted a sequential exploratory mixed methods design. First, the authors interviewed 19 social media managers in education, health and social service nonprofit organizations to identify the varieties in service co-creation realized. Second, the authors surveyed 73 nonprofit organizations on social media and gathered 267 useable responses, which were used to analyze and validate the identified forms of service co-creation.
Findings
The authors found that nonprofit organizations realize up to seven forms of service co-creation using social media. These include co-ideating to tweak service ideas, co-diagnosing social needs and problems, co-assessing service events, co-transforming services to targeted communities, co-advocating for community and service reach, co-resourcing in service delivery, and co-experiencing through a pool of diverse service experiences.
Originality/value
This study develops a reliable and valid multidimensional measure for nonprofit service co-creation enabled by social media platforms. Theoretically, this study offers a nonprofit service co-creation model to drive nuanced explanatory research and service co-creation perspectives in other contexts and engagement platforms. Managerially, this research illustrates the variations in service co-creation, which inform the strategic value of social media to nonprofits and will assist nonprofit practitioners in planning and evaluating their service co-creation outcomes
Ubuntu in the Diaspora: Its Conservation and Comparison With Other World Views
No full textAs people live in cross-cultural contexts, there is a need to recognize and appreciate the role of different worldviews and how they shape our understanding of humanity, upbringing, and engagement in social or work environments. The key starting point to enable this is exploring the often-overlooked indigenous philosophies of life such as Ubuntu and examining how such value systems survive alongside opposing or similar traditions. This chapter improves the understanding of cultural values by discussing the central tenets of the African philosophy of Ubuntu, in comparison to the Western ways of life and the strategies that Africans in the diaspora are applying to preserve Ubuntu values. Strategies for promoting Ubuntu in the education system and community settings are also recommended with the goal of enhancing cross-cultural awareness
Increased air temperature during repeated-sprint training in hypoxia amplifies changes in muscle oxygenation without decreasing cycling performance
No full textThe present study aims to investigate the acute performance and physiological responses, with specific reference to muscle oxygenation, to ambient air temperature manipulation during repeated-sprint training in hypoxia (RSH). Thirteen male team-sport players completed one familiarisation and three experimental sessions at a simulated altitude of ∼3000 m (FIO2 0.144). Air temperatures utilised across the three experimental sessions were: 20°C, 35°C and 40°C (all 50% relative humidity). Participants performed 3 × 5 × 10-s maximal cycle sprints, with 20-s passive recovery between sprints, and 5 min active recovery between sets. There were no differences between conditions for cycling peak power, mean power, and total work (p>0.05). Peak core temperature (Tc) was not different between conditions (38.11 ± 0.36°C). Vastus lateralis muscle deoxygenation during exercise and reoxygenation during recovery was of greater magnitude in 35°C and 40°C than 20°C (p0.05). Exercise-induced increases in blood lactate concentration were higher in 35°C and 40°C than 20°C (p=0.010 and p=0.001, respectively). Integrating ambient temperatures up to 40°C into a typical RSH session had no detrimental effect on performance. Additionally, the augmented muscle oxygenation changes experienced during exercise and recovery in temperatures ≥35°C may indicate that the potency of RSH training is increased with additional heat. However, alterations to the training session may be required to generate a sufficient rise in Tc for heat training purposes

Trust and Money or Value Transfers: A study of the implications of global value conflict generated by UN Security Council Resolution 1373
Get PDFTrust is a fundamental aspect of any given functional society. However, since late September 2001, the UN approach to global financial governance appears to have been driven by distrust of other less formalized money or value transfer (MVT) systems. At the core of this ‘Global Regulatory Effort’ (GRE) is UN Security Council Resolution (UNSCR) 1373, which mandated that states legislate to regulate all informal MVT systems. In particular, the MVT system known as ‘hawala’ was implicated by US authorities in the funding of the acts of terrorism committed on September 11 in 2001.
Although the focus of this multilateral effort was predominantly on the Islamic hawala system, the regime targeted any MVT system not linked to an established commercial banking operation. In this way UNSCR 1373 put a line in the sand between trustworthy and untrustworthy financial service providers. The necessity of this unprecedented step was ostensibly in order to prevent any future global acts of terrorism and maintain international peace and security. However, the regime’s approach implicitly legitimized formal Westernstyle financial systems while delegitimising all others. This study contends that a significant implication of this securitized approach to global financial governance was the creation of a Global Trust Conflict (GTC).
The Global Financial Crisis of 2007/2008 and the adoption of Bitcoin as legal tender by El Salvador emphasize the significance of this Conflict. Moreover, the emergence of blockchain technology, Decentralized Finance (DeFi), and Distributed Ledger Technology (DLT) represents a new and challenging front in which the implications of the Conflict may be significant. Particularly in terms of the prevailing nature of trust provision services throughout the global economy. As a result, new possibilities for the shape of global order have arisen as state and private interests compete to influence the future of remittances. This research argues that the UNSCR 1373 mandate is anti-competition and served to institutionalize distrust of non-bank MVT systems. This includes traditionally informal remittances and emergent decentralized value transfer systems built on blockchain technology. This thesis concludes that a Global Trust Conflict exists, which constitutes the most significant barrier to regulatory efficacy and compliance aimed at MVT systems
Increases in Integrin–ILK–RICTOR–Akt Proteins, muscle mass, and strength after eccentric cycling training
No full textPurpose
Recently, it has been suggested that a cellular pathway composed of integrin, integrin-linked kinase (ILK), rapamycin-insensitive companion of mTOR (RICTOR), and Akt may facilitate long-term structural and functional adaptations associated with exercise, independent of the mTORC1 pathway. Therefore, we examined changes in integrin–ILK–RICTOR–Akt protein in vastus lateralis (VL) before and after 8 wk of eccentric cycling training (ECC), which was expected to increase muscle function and VL cross-sectional area (CSA).
Methods
Eleven men (23 ± 4 yr) completed 24 sessions of ECC with progressive increases in intensity and duration, resulting in a twofold increase in work from the first three (75.4 ± 14.1 kJ) to the last three sessions (150.7 ± 28.4 kJ). Outcome measures included lower limb lean mass, VL CSA, static strength, and peak and average cycling power output. These measures and VL samples were taken before and 4–5 d after the last training session.
Results
Significant (P < 0.05) increases in integrin-β1 (1.64-fold) and RICTOR (2.99-fold) protein as well as the phosphorylated-to-total ILK ratio (1.70-fold) were found, but integrin-α7 and Akt did not change. Increases in lower limb, thigh, and trunk lean mass (2.8%–5.3%, P < 0.05) and CSA (13.3% ± 9.0%, P < 0.001) were observed. Static strength (18.1% ± 10.8%) and both peak (8.6% ± 10.5%) and average power output (7.4% ± 8.3%) also increased (P < 0.05). However, no significant correlations were found between the magnitude of increases in protein and the magnitude of increases in CSA, static strength, or power output.
Conclusions
In addition to increased muscle mass, strength, and power, we demonstrate that ECC increases integrin-β1 and RICTOR total protein and p-ILK/t-ILK, which may play a role in protection against muscle damage as well as anabolic signaling to induce muscle adaptations
Changes in plasma hydroxyproline and plasma cell-free DNA concentrations after higher- versus lower-intensity eccentric cycling
No full textPurpose
We examined changes in plasma creatine kinase (CK) activity, hydroxyproline and cell-free DNA (cfDNA) concentrations in relation to changes in maximum voluntary isometric contraction (MVIC) torque and delayed-onset muscle soreness (DOMS) following a session of volume-matched higher- (HI) versus lower-intensity (LI) eccentric cycling exercise.
Methods
Healthy young men performed either 5 × 1-min HI at 20% of peak power output (n = 11) or 5 × 4-min LI eccentric cycling at 5% of peak power output (n = 9). Changes in knee extensor MVIC torque, DOMS, plasma CK activity, and hydroxyproline and cfDNA concentrations before, immediately after, and 24–72 h post-exercise were compared between groups.
Results
Plasma CK activity increased post-exercise (141 ± 73.5%) and MVIC torque decreased from immediately (13.3 ± 7.8%) to 48 h (6.7 ± 13.5%) post-exercise (P < 0.05), without significant differences between groups. DOMS was greater after HI (peak: 4.5 ± 3.0 on a 10-point scale) than LI (1.2 ± 1.0). Hydroxyproline concentration increased 40–53% at 24–72 h after both LI and HI (P < 0.05). cfDNA concentration increased immediately after HI only (2.3 ± 0.9-fold, P < 0.001), with a significant difference between groups (P = 0.002). Lack of detectable methylated HOXD4 indicated that the cfDNA was not derived from skeletal muscle. No significant correlations were evident between the magnitude of change in the measures, but the cfDNA increase immediately post-exercise was correlated with the maximal change in heart rate during exercise (r = 0.513, P = 0.025).
Conclusion
Changes in plasma hydroxyproline and cfDNA concentrations were not associated with muscle fiber damage, but the increased hydroxyproline in both groups suggests increased collagen turnover. cfDNA may be a useful metabolic-intensity exercise marker
