Control, camaraderie and resistance: Precarious work and organisation in hospitality

With industrial action recently taking place at TGI Fridays, McDonald’s and Wetherspoons, the organisation of precarious workers within the hospitality industry has received renewed attention in popular and academic circles. The subject of this article is the result of a year’s worth of work, research and activism alongside co-workers within the sector. It takes the form of an insiders’ ethnography, positioning itself as an example of workers’ inquiry into precarious workplaces and collective resistance. The research addresses the subject of affective labour in customer-facing hospitality work, with particular attention paid to the sociability of the labour process. It also addresses the issues of the composition of labour and the material conditions that act as the driving force of precarity, while assessing the contours of flexibility, control and resistance. The wider social character of the work and the workers themselves, as well as the community and camaraderie of the workplace, is also studied. Using the 2018 TGI Fridays strike as a key example, the article outlines how, in harnessing the camaraderie of such social and communal work, workers have sought to realise their autonomy and resist precarity through collective struggle.
A Meta-Analysis of Reform-based Professional Development in STEM: Implications for Effective Praxis

A systematic review and meta-analysis was conducted to examine the effects of reform-based professional development on mathematics and science teachers Pedagogical Content Knowledge (PCK). An exhaustive literature search returned 15 studies, from which 21 independent effect sizes were extracted. These studies included, K-12 pre- and in-service mathematics and science teachers as participants ( N = 1,044). The mean overall effect size was statistically significant ( d = 0.51, p < 0.001). Heterogeneity analysis revealed consistency throughout the studies based on a non-significant value for the Q statistic. This suggests that the variance between studies was not more than what would be expected by random error. The variation in study characteristics warranted an examination of possible moderators, despite the absence of statistically significant heterogeneity. Teacher type (in-service vs. pre-service), subject (mathematics vs. science), and outcome measures were all non-statistically significant moderators of the effect size. The results of this study are substantial because they suggest that the effects of reform-based professional development are consistent across settings and teaching populations. Additionally, this suggests that the relationship between reform-based professional development and PCK are robust. Other implications and recommendations for professional development to maximize opportunities to learn in STEM classrooms are also provided.
Enhanced Frequency Droop Method for Decentralized Power Sharing Control in dc Microgrids

This article proposes two novel approaches to improve the superimposed frequency droop scheme for the control of dc microgrids (MGs). Conventional voltage-based control strategies suffer from issues such as undesirable voltage regulations, poor power sharing among the sources, and negative effects of line resistances on the equivalent droop characteristics. To overcome these challenges, a superimposed frequency droop scheme has been introduced. However, this method suffers from three major issues: 1) instability in terms of load variation, which is due to the location of system dominant poles; 2) limitation in system loading due to the limitation in the transferred reactive power; and 3) poor voltage quality caused by injection of the ac voltage. In this article, two methods are presented to stabilize the system and enhance its loading condition, consequently improving its viability for control of the dc MG. Furthermore, the system voltage quality is improved by limiting the amplitude of the injected ac voltage. The effectiveness of the proposed schemes is shown by different simulations and is further validated by experiments.

Essentiality of managing the resource information in the coordinated fog‐to‐cloud paradigm

Fog‐to‐cloud (F2C) computing is an emerging computational platform. By combing the cloud, fog, and IoT, it provides an excellent framework for managing and coordinating the resources in any smart computing domain. Efficient management of these kinds of diverse resources is one of the critical tasks in the F2C system. Also, it must be considered that different types of services are offered by any smart system. So, before managing these resources and enabling the various types of services, it is essential to have some comprehensive informational catalogue of resources and services. Hence, after identifying the resource and service‐task taxonomy, our main aim in this paper is finding out a solution for properly organizing this information over the F2C system. For that purpose, we are proposing a modified F2C framework where all the information is distributively stored near to the edge of the network. Finally, by presenting some experimental results, we evaluate and validate the performance of our proposing framework.
DEVELOPMENT OF A CIRCULARLY POLARIZED HMSIW ANTENNA

A circularly polarized (CP) half-mode substrate integrated waveguide (HMSIW) cavitybacked antenna is developed by a novel design method in this paper. The single-fed antenna contains two coupled HMSIW cavities with orthogonal polarizations. Its design method evolves from filter synthesis procedure, which takes the advantage of equivalent circuit model to accelerate the optimization. The antenna radiates high-purity right handed CP waves with measured axial ratio (AR) of 0.33 dB at 3.55 GHz, while its gain and AR bandwidth are comparable to other CP SIW antennas. With the robust design method, the proposed antenna is competitive in practical applications.
Smoker identity and resistance to antismoking campaigns: The role of group entitativity

Past works have shown that identification with smokers predicts increased resistance to antismoking campaigns. In this research, we hypothesized that group entitativity, because it affects the extent to which people feel committed to act for their group, can mitigate this link. We conducted two studies with convenient samples of smokers that both included a measure of identification and measured (Study 1) or manipulated (Study 2) entitativity. Then, participants read an antismoking message and, finally, reported their attitude toward smoking (Studies 1 and 2), as well as their urge to smoke and intention to quit (Study 2). Consistently, both studies revealed more resistance among high (vs. low) identifiers, but only when they perceived smokers as a highly entitative group. These findings emphasized the importance of group processes and social identity factors for accounting for responses to antismoking information.
USEFULNESS OF PULSE OXIMETRY IN ASSESSMENT OF DYSPNOEA IN ASTHMA

Background: This study was carried out to find usefulness of pulse oximetry in assessment of dyspnoea patients with asthma. Methods: This study was carried out at Baqai Medical University Teaching Hospital. Fifty-three patients, 28 males and 25 females, suffering from asthma with age ranging between 16 to 70 years were included. They were subjected to Pulse Oximetry before and after the bronchodilator treatment when presented with acute dyspnoea. Simultaneous recording of spirometry was also done. Results: Mean oxygen saturation (SaO2) increased from 93.11±4.33 to 95.17±3.59 percent (p<0.0001) as dyspnoea improved after bronchodilator treatment. Mean FVC increased from 1.81±0.84 to 2.21±0.92 L (p<0.01). Mean FEV1 increased from 1.21±0.73 to 1.62±0.85 L (p<0.01). Mean PEFR increased from 1.67±1.07 to 2.31±1.28 L/min (p<0.0001). Mean percentage ratio (FEV1/FVC) increased from 66.47±18.01 to 71.19±16.47 percent (p<0.0001). The correlation was found between SaO2 and FEV1, FVC and PEFR with R 2 =0.1149, R 2 =0.2487 and R 2 =0.3193 respectively. Conclusion: Pulse Oximetry like spirometry is reliable for assessment of dyspnoea. Both are correlated. Pulse oximetry has value in assessment of dyspnoea in asthma.
Quad‐port ring dielectric resonator based MIMO radiator with polarization and space diversity

In this communication, quad port MIMO antenna is designed and examined. It is designed by ring shaped ceramic material. The main attribute of proposed analysis are: (a) dual radiating modes are created in the ring shaped ceramic resonator, that is, HE11δ and HE12δ mode with the assistance of pentagon ring shaped aperture; (b) with the help of polarization and space diversity, the mutual coupling is lower than −20 dB among the ports; and (c) ring shaped ceramics provides better bandwidth performance as compare to cylindrical shaped ceramic. Measured results of fabricated protytpe confirms that the proposed radiator functions over two frequency ranges, that is, 2.45 to 2.75 GHz and 4.8 to 5.75 GHz. The value of ECC is also within the limit. All these features make the radiator applicable for wireless local area network (2.4 GHz) and WiMAX (2.5/5.1 GHz) applications.
Control de una prótesis de mano para varios tipos de prensión empleando comandos de voz

Este documento presenta el desarrollo de un estudio cinematico de la mano empleando un sistema de captura de movimiento por camaras infrarrojas y marcadores para posterior control de un prototipo de protesis de mano. El objetivo es definir parametros cinematicos que permitan diferenciar cuatro tipos de agarre distintos y para ello se llevaron a cabo diferentes sesiones de captura de movimiento, logrando un total de 30 grabaciones por movimiento, logrando un total de 120 grabaciones. El analisis cinematico indica que existe una tendencia en las articulaciones de los dedos a presentar tres fases: acercamiento, cierre y sostenimiento. Centrando el estudio en la fase de cierre fue posible encontrar rangos angulares y duraciones de los cierres para los distintos tipos de agarre. Adicionalmente, se busco desarrollar un sistema de control por movimientos (cierres o agarres) predefinidos en un prototipo de protesis de mano, buscando cumplir con los parametros cinematicos hallados a partir de la captura de movimiento. Al final se logro construir un sistema de control en el entorno Matlab® que, enlazado con una tarjeta Arduino®, es capaz de reconocer diferentes comandos de voz y accionar el prototipo de protesis para diferentes movimientos predefinidos.

Background. Iodine deficiency disorders are important public health priority globally as well as in India. The pre- sent study was undertaken to determine the prevalence of utilization of adequately iodized salt at house-hold level among rural community in Nalgonda district of Telangana. Methodology. One hundred and fifty-four households were interviewed for knowledge regarding iodine deficiency disorders, socio-demo- graphic profile and cultural practices related with purchase and storage of salt. A sample of salt from each household was tested for adequate presence (> 15ppm), inadequate presence (< 15 ppm) and absence of iodine. Results. The study revealed that 83.1% of households were using adequately iodized salt, 7.8% were using inadequately iodized salt while 9.1% were using salt that has no iodine. Use of crystal salt and open storage of salt were significantly associated with non-utilization of adequately iodized salt. Conclusion. Health education of the community regarding Iodine deficiency disorders and its prevention through use of iodized salt is recom- mended.
Biochemische und biophysikalische Charakterisierung von Rhodopsin-Guanylylzyklasen

Rhodopsin-Guanylylzyklasen (RhGC) sind einzigartige Photorezeptoren, die kurzlich in Pilzen der Abteilung Blastocladiomycota entdeckt wurden [1]. RhGCs gehoren zu den Enzym-Rhodopsinen und die Licht-sensitive mikrobielle Rhodopsin Domane ist kovalent mit einer Typ III Guanylylzyklase verbunden. Guanylylzyklasen bilden den sekundaren Botenstoff cGMP, der zusammen mit cAMP eine Vielzahl biologischer Prozesse reguliert [2–12]. In der vorliegenden Arbeit wurden die funf neu-entdeckten RhGCs mithilfe unterschiedlicher biochemischer und biophysikalischer Methoden charakterisiert. Elektrophysiologische Messungen erbrachten einen indirekten Nachweis fur eine Grunlicht-aktivierte cGMP Synthese bei den RhGCs aus Blastocladiella emersonii (Be) und Catenaria anguillulae (Ca). Die Licht-aktivierte Guanylylzyklasen Funktion dieser RhGCs konnte durch ELISA Experimente und nach Aufreinigung der Photorezeptoren bestatigt werden. Belichtung fuhrte zu einer 100-fachen oder 200-fachen Erhohung von cGMP mit einem vmax von 1.8 oder 11.6 µmol/min/mg(Protein) bei BeRhGC oder CaRhGC. Im Dunkeln verblieb bei beiden Photorezeptoren die cGMP-Konzentration auf dem Niveau von Kontrollzellen. Durch eine enzymkinetische Analyse der isolierten Guanylylzyklase Domanen (Be/CaGC) konnte die konstitutive Aktivitat der enzymatischen Einheit gezeigt werden, die im Vergleich zu den Volllangen Photorezeptoren 3-6x reduziert war. Weiterhin wurden die Photozyklen der isolierten Rhodopsin Domanen mithilfe spektroskopischer Methoden untersucht und Photointermediate identifiziert, die typisch fur mikrobielle Rhodopsine sind. Die M-Intermediate zerfielen langsam mit τ ~ 100 ms bei BeRh und τ ~ 500 ms bei CaRh. Um die kinetischen und spektroskopischen Parameter der Photorezeptoren zu verandern, wurden die Be/Ca Rhodopsin Domanen mutiert. Zusatzlich wurde die Substratspezifitat der RhGCs geandert und eine Doppelmutation (E497K/C566D) in der katalytischen Domane erzeugte Rhodopsin-Adenylylzyklasen (RhACs). Die Licht-induzierte cAMP Synthese der RhACs wurde in Xenopus Oocyten getestet und im Vergleich zu BeRhAC zeigte CaRhAC eine erhohte Licht-zu-Dunkel-Aktivitat (6x) einhergehend mit einer verringerten Dunkelaktivitat (5.5x). Um weitere Einblicke in die kurzlich entdeckten RhGCs zu erhalten, wurden die isolierten Zyklase Domanen, Be/CaGC und CaAC, in Gegenwart von NTP Analoga kristallisiert. Neben hochauflosenden monomeren GC Strukturen ohne Ligand wurde eine 2.25 A Struktur der mutierten Zyklase, CaAC, mit dem ATP Analogon ATPαS gelost. Die CaAC Struktur zeigt ein antiparalleles Arrangement der Dimer-Untereinheiten und die Bindung der Nukleotidbase durch die zuvor mutierten Reste. Aufgrund der Ahnlichkeit zu anderen Typ III Zyklasen kann auf einen klassischen Reaktionsablauf bei RhGCs ruckgeschlossen werden. Abschliesend wurde die Anwendbarkeit von Ca/BeRhGC sowie CaRhAC in hippokampalen Rattenneuronen und CHO Zellen getestet. Diese Experimente zeigen, dass sowohl RhGCs als auch YFP-CaRhAC als optogenetische Werkzeuge eingesetzt werden konnen, um die…
How work engagement influences relationship quality: the roles of work motivation and perceived service guarantee strength

It is expected that the population of Generation Y will soon outnumber that of the Baby Boomers and become the largest portion of the overall workforce. However, previous studies have rarely focused on Generation Y employees, and these studies did not consider how different types of work motivations affect employee engagement among Generation Y employees. Thus, based on the self-determination theory, this study investigated how different work motivations affect Generation Y employees’ work engagement and how the perceived service guarantee strength (PSGS) mediates the relationship between employee engagement (a firm-level variable) and relationship quality (RQ; an individual-level variable). Responses were collected from Generation Y employees and customers in the hotel industry. A multilevel design and hierarchical linear modelling analysis were employed. The results indicated that among the four work motivations, task enjoyment had the strongest effect on engagement among Generation Y employees, followed by compensation seeking, recognition seeking, and challenge seeking. Additionally, a partial cross-level mediation effect was found in the relationships among employee engagement, PSGS, and RQ. The findings suggest that hospitality managers should support and motivate staff to increase employee engagement and ensure that employees provide the best possible customer service, which should, in turn, improve customer relationships.
Comprensión fenomenológica del trastorno déficit de atención con hiperactividad (TDAH) en adolescentes

El TDAH es una de las patologías más investigadas en la actualidad, sin embargo, una mirada fenomenológica sobre ese fenómeno aún es nueva. Buscamos comprender la vida de adolescentes con TDAH desde la perspectiva teórica de Merleau-Ponty y Arthur Tatossian. Ambos priorizaban el contacto directo con el sujeto, transcendiendo una separación entre teoría y práctica al pretender el Lebenswelt. Utilizamos el método fenomenológico crítico en que entrevistamos ocho adolescentes. Esta pesquisa miró los modos de existencia que no se restringen al patológico, ampliando la mirada de los síntomas a una comprensión de los sentidos atribuidos. Concluimos que en la hiperactividad el mundo es experimentado como más lento, llevando a los sujetos a precipitarse en las acciones, producirse pensamientos con poca conexión y una dificultad en mantener la atención y el autocontrol, y la presencia de baja autoestima. Comprender el TDAH y su experiencia fue importante para los adolescentes al favorecer el cambio, saliendo del enfoque de la enfermedad para considerar sus potencialidades. Palabras clave: trastorno de la falta de atención con hiperactividad, adolescencia, fenomenología.
Development and Validation of a General and Robust Methodology for the Detection and Classification of Gas Turbine Sensor Faults

Sensor fault detection and classification is a key challenge for machine monitoring and diagnostics, since raw data cleaning represents a key process in the gas turbine industry. To this end, this paper presents a comprehensive approach for detection, classification, and integrated diagnostics of gas turbine sensors (named DCIDS), which was previously developed by the authors and has been substantially improved and validated by means of field data. For a single sensor or redundant/correlated sensors, the improved diagnostic tool, called improved-DCIDS (I-DCIDS), can identify seven classes of faults, i.e., out of range, stuck signal, dithering, standard deviation, trend coherence, spike, and bias. First, this paper details the I-DCIDS methodology for sensor fault detection and classification. The methodology uses basic mathematical laws that require some user-defined configuration parameters, i.e., acceptability thresholds and windows of observation. Second, a sensitivity analysis is carried out on I-DCIDS parameters to derive some rules of thumb about their optimal setting. The sensitivity analysis is performed on four heterogeneous and challenging datasets with redundant sensors acquired from Siemens gas turbines (GTs). The results demonstrate the diagnostic capability of the I-DCIDS approach in a real-world scenario. Moreover, the methodology proves to be suitable for all types of datasets and physical quantities and, thanks to its optimal tuning, can also identify the exact time point of fault onset.
