The evaluation turn in the higher education system: lessons from Italy

This article explores how new public management policy ideas and technologies circulating in the globalised education space have been re-contextualised in the re-design of the Italian Higher Education System. In doing so, it uses the governmentality studies as a sensitising framework to problematise what we term here as the ‘calculative and instrumental turn’ in the evaluation of Higher Education. The work reflects on the complex assemblage of forms of knowledge, technical means and collective and individual subjects through which the evaluation of the Italian universities unfolds in its current form. The attempt is to highlight the changes produced in how Higher Education and its ethical subjects are thought and their qualities are conceived and appraised. The article presents some conclusive remarks on some of the paradoxical risks of the Evaluation turn, namely contractualisation, depoliticisation and fabrication, but also insists on its reflexivity potential, interpreting the current developments as a missed opportunity.     

Electrical and mechanical response of skeletal muscle to electrical stimulation after acute passive stretching in humans: a combined electromyographic and mechanomyographic approach

Two mechanisms have been suggested to explain stretching-induced maximum force depression: a mechanical alteration in the stretched muscle and an impairment of neural activation. Electrical stimulation allows standardization of the level of muscle activation without being limited by neural control. The aim of this study was to evaluate the stretching-induced changes in the electrical and mechanical properties of muscle during electrically elicited contractions. Twelve participants (age 22 +/- 1 years; body mass 75 +/- 2 kg; stature 1.79 +/- 0.02 m; mean +/- standard error) underwent six electrical stimulations of the medial gastrocnemius muscle before and after stretching. During the contractions, surface electromyogram (EMG) and mechanomyogram (MMG) were recorded simultaneously together with force. After stretching we found: (i) no differences in EMG parameters; (ii) MMG amplitude decreased by 4 +/- 1% (P < 0.05); and (iii) the peak force, the peak rate of force development, and the acceleration peak of force development decreased by 12 +/- 3%, 14 +/- 1%, and 24 +/- 5%, respectively (P < 0.05). In conclusion, acute passive stretching did not change EMG properties but altered the mechanical characteristics of the contracting muscle. Indeed, muscle force-generating capacity and stiffness of the muscle-tendon unit were significantly impaired.     

The reforming trajectory of the Italian educational system. Site‐based management and decentralisation as a challenge for democratic discourse

This article aims to present some tensions embedded in the Italian educational reform, arising both from the enactment of neo‐liberal policies and the possibilities of democratic development opened up by the introduction of schools’ site‐based management and decentralisation. The article uses discourses as heuristic devices and presents two case studies regarding the enactment of policies of educational governance promoted in 2003 by a local authority (the Italian Provincia) and inspired by the democratic discourse. These policies were intended to promote the participation and collaboration of schools and heads in educational planning. It illustrates how the neo‐liberal discourse re‐shaped the Italian educational system and challenged welfarism. At the same time, we also attempt to illustrate the action of cultural path dependencies and the space emerging for a democratic discourse, which could be interpreted both as an alternative to its neo‐liberal counterpart and as an attempt to re‐discover democratic participation and promote more equity‐oriented practices in the educational field. Two different understandings of educational governance and headship seem to emerge. The study underlines how the intertwining of national and local policies inspired by contradicting discourses could result in the spread of competitive practices and consequently in a further differentiation of the educational provision and stratification between schools, or have an egalitarian outcome, where processes of collaboration, collective empowerment and reflexivity are enacted. Our work demonstrates how democratic and collaborative spaces opened up by site‐based management and policies of educational governance implemented at a local level are always at risk, due both to the rise of competitive pressures and the resilience of welfarist discourses and practice.     

Stretching and deep and superficial massage do not influence blood lactate levels after heavy-intensity cycle exercise

Abstract

The study aimed to assess the role of deep and superficial massage and passive stretching recovery on blood lactate concentration ([La^?]) kinetics after a fatiguing exercise compared to active and passive recovery. Nine participants (age 23 ± 1 years; stature 1.76 ± 0.02 m; body mass 74 ± 4 kg) performed on five occasions an 8-min fatiguing exercise at 90% of maximum oxygen uptake, followed by five different 10-min interventions in random order: passive and active recovery, deep and superficial massage and stretching. Interventions were followed by 1 hour of recovery. Throughout each session, maximum voluntary contraction (MVC) of the knee extensor muscles, [La^?], cardiorespiratory and metabolic variables were determined. Electromyographic signal (EMG) from the quadriceps muscles was also recorded. At the end of the fatiguing exercise, [La^?], MVC, EMG amplitude, and metabolic and cardiorespiratory parameters were similar among conditions. During intervention administration, [La^?] was lower and metabolic and cardiorespiratory parameters were higher in active recovery compared to the other modalities (P < 0.05). Stretching and deep and superficial massage did not alter [La^?] kinetics compared to passive recovery. These findings indicate that the pressure exerted during massage administration and stretching manoeuvres did not play a significant role on post-exercise blood La^? levels.     

Acute passive stretching in a previously fatigued muscle: Electrical and mechanical response during tetanic stimulation

Abstract

The aim of this study was to assess the effects of acute passive stretching on the electrical and mechanical response of a previously fatigued muscle. Eleven participants underwent maximal tetanic stimulations (50 Hz) of the medial gastrocnemius, before and after a fatiguing protocol and after a bout of passive stretching of the fatigued muscle. During contraction, surface electromyography (EMG), mechanomyography (MMG), and force were recorded. The following parameters were calculated: (1) the EMG root mean square (RMS), mean frequency, and fibre conduction velocity; (2) MMG peak-to-peak and RMS; (3) the peak force, contraction time, half-relaxation time, peak rate of force development (dF/dt) and its acceleration (d² F/dt ²). Fatigue reduced peak force by 18% (P < 0.05) and affected the other force, EMG, and MMG parameters. After stretching: (1) all EMG parameters recovered to pre-fatigue values; (2) MMG peak-to-peak remained depressed, while RMS recovered to pre-fatigue values; (3) the peak force, peak rate of force development and its acceleration were further reduced by 22, 18, and 51%, respectively, and half-relaxation time by 40% (P < 0.05). In conclusion, acute passive stretching, when applied to a previously fatigued muscle, further depresses the maximum force-generating capacity. Although stretching does not alter the electrical parameters of the fatigued muscle, it does affect the mechanical behaviour of the muscle–tendon unit.     

Sex-Related Responses to Eccentric-Only Resistance Training in Knee-Extensors Muscle Strength and Architecture

Purpose: The present study aimed to investigate whether or not eccentric-only training induced different sex-related adaptations in vastus lateralis muscle architecture and knee extensors strength. Methods: Thirteen healthy women and 13 healthy men were recruited. Vastus lateralis pennation angle, fascicle length, and muscle thickness, as well as knee extensors eccentric, isometric, and concentric peak torque and one-repetition maximum (1RM) were measured. Both women and men underwent a unilateral iso-load knee-extension eccentric-only training with 120% of the concentric 1RM, consisting of 4 sets × 10 repetitions twice a week for a total of 8 weeks. Results: Pennation angle increased in women (+ 14%, 95% CI [10, 17], effect size [ES] = 1.54) but not in men (+ 5%, 95% CI [?1, 11], ES = 0.28), while fascicle length increased in both women (+ 7%, 95% CI [4, 10], ES = 1.02) and men (+ 12%, 95% CI [8, 16], ES = 1.82) and muscle thickness increased in women (+ 13%, 95% CI [8, 18], ES = 1.11) and men (+ 11%, 95% CI [7, 15], ES = 0.89). In both women and men, eccentric (18%, 95% CI [11, 25], ES = 0.96, and 16%, 95% CI [9, 22], ES = 0.82, respectively), isometric (17%, 95% CI [11, 23], ES = 0.53, and 17%, 95% CI [10, 24], ES = 0.62), concentric (12%, 95% CI [7, 16], ES = 0.49, and 9%, 95% CI [5, 13], ES = 0.42) peak torque and 1RM (10%, 95% CI [6, 14], ES = 0.53, and 10%, 95% CI [5, 15], ES = 0.50) similarly increased after the intervention. Conclusions: This study showed that the adaptations in strength are not sex-dependent, but the increases in pennation angle only in women suggest that the changes in muscle architecture may depend on sex.     

Neoliberalism and the marginalisation of social justice: the making of an education policy to combat social exclusion

The paper analyses how the establishment of neoliberalism, as the new global orthodoxy, in the field of education implies a substantial subjugation and marginalisation of policies and practices informed by the values of social justice and equity. The evidence from a case study on an inclusive education policy enacted to combat social exclusion and dropout in a disadvantaged inner-city area in the south of Italy are presented. The study shows how neoliberalism is increasingly re-defining the domains of validity, normativity and actuality according to an economic rationale; within these domains the actors frame the problems of social exclusion and dropout and choose the solutions to address them. It is argued that the overall framework of discourses of human capital, individualisation, school improvement, performativity and standardisation impedes any contextualised, multidimensional and critical approach to social exclusion as well as the pursuing of any egalitarian outcomes, be they (re)distributional, cultural or associational outcomes.     

Analysing policy in the context(s) of practice: a theoretical puzzle

This essay contributes to the construction of a critically informed toolbox of diverse concepts for education policy analysis. Focusing on the context(s) of practice of the policy cycle, the article outlines an interpretative framework to grasp policy enactment across different localities, the influences bearing upon those enactments as well as their intended and unintended consequences. It has the underlying theoretical concern of building bridges between modern and postmodern approaches in policy analysis. The argument develops through three steps. First, it conceptualizes policy as discourse taking seriously the postmodern concerns with the discursive and power/knowledge regimes. The adoption of some concepts offered by Foucault’s archaeology allows the mapping of the generative interrelations linking policies to wider discursive contexts. Second, the postmodern sensibility is balanced with the introduction of heuristic devices drawn from the strategic relational approach and structuration theory to take into account the structural arrangements setting the possibilities and the conditions of policy enactment. Third, the bridging between modern and postmodern approaches is completed through the acceptance of a dialectic between subject decentring and recentring. A composite conceptualization of the agent’s internal structures is proposed to analyse how people can make a difference exerting their agentic powers.     

Noninvasive physicochemical characterization of two 19th century English ferrotypes

The present work was one of the first attempts to analyze the conservation status of two ferrotypes, ancient photographic plates realized on a support made of iron. The photographic material was constituted of collodion as binder for the photosensitive silver halides grains. The two ferrotypes studied belonged to a private collection of a family from Durham, UK, and were made at the end of the 19th century. The analytical techniques used for the morphological and physicochemical characterization were noninvasive. The surface morphology was studied by means of optical microscopy (OM) and environmental scanning electron microscopy (ESEM) coupled with an energy dispersive X-rays (EDX) system for the elemental analysis. These techniques, together with microreflectance Fourier transform infrared spectroscopy (μ-FTIR) and contact angle, allowed to obtain information on both the chemical – elemental – composition of the materials constituting the ferrotypes, and the conservation status of these photographic plates. The study showed that the physicochemical diagnostics allowed to characterize the two ferrotypes that, despite their similar age and provenance, showed different conservation status, surface properties, and elemental composition.
