Challenge to Managers: Changing Hotel Work from a Secondary Choice to career Development

In his discussion - Challenge To Managers: Changing Hotel Work from a Secondary Choice to Career Development - by Leonidas Chitiris, Lecturer in Management, Piraeus Graduate School of Industrial Studies, Athens, Greece, Chitiris marginally alludes at the outset: “Surveys and interviews with hotel employees in Greece with regard to why individuals work for hotels and to what extent their rationale to join the hotel industry affects hotel productivity revealed that the choice to work in hotels is a secondary preference and reflects the opportunity structure in the economy at any given time and the greater the number of those who work in hotels when there are no other employment opportunities, the less likely the chances for overall improved performance. Given the increase in the proportion of unskilled, unmotivated workers, the level of hotel productivity consequently decreases! The author interprets the findings in terms of the economic and employment conditions in the Greek hotel industry. To enhance the rationale of his thesis statement, Chitiris offers with citation: “Research on initial entry into the labor force has shown that new employees reflect idealized expectations and are frequently not very satisfied with their jobs and roles in the work settings.” Chitiris advances the thought even further by saying: “Research on job satisfaction, motivation, and production purports that management can initiate policies that develop job satisfaction and may improve productivity.” The author outlines components within the general category of the hotel industry to label and quantify exactly why there may be a lag between employee expectations and the delivery of a superior level of service. Please keep in mind that the information for this essay is underpinned by the hotel industry in Greece, exclusively. Demographic information is provided. One example of the many factors parsed in this hotel service discussion is the employee/guest relationship. “The quality of service in hotels is affected to a great extent by the number of guests a hotel employee has to serve,” Chitiris offers. Additionally, Chitiris’ characterization of the typical hotel employee in Greece is not flattering, but it is an informed and representative view of that lodging labor pool. The description in and of itself begs to explain at least some of why the hotel industry in Greece suffers a consequently diminished capacity of superior service. Ill equipped, under-educated, over-worked, and under-paid are how Chitiris describes most employees in the Hellenist hospitality field. Survey based studies, and formulaic indices are used to measure variables related to productivity; the results may be inconclusive industry wide, but are interesting nonetheless. Also, an appealing table gauges the reasons why hotel workers actually employ themselves in the lodging industry. Chirtiris finds that salary expectations do not rate all that high on the motivational chart and are only marginal when related to productivity. In closing, Chirtiris presents a 5-phase development plan hotels should look to in improving performance and productivity at their respective properties.

Intervención en el parque de la juventud en la parroquia urbana General Leonidas Plaza

La ciudad de General Leónidas Plaza, localizada en el Cantón Limón Indanza en la Amazonía del Ecuador, posee una serie de recursos naturales y culturales tangibles e intangibles que deben ser resguardados y potencializados. Esta ciudad, es un asentamiento con pocos años de fundación por lo que se encuentra en constante desarrollo económico y social. Estos cambios y transformaciones demandan espacios que permitan la interacción social de la población a través de la generación de zonas de esparcimiento y recreación. Los espacios de recreación en la cabecera cantonal, presentan deficientes condiciones en cuanto a su funcionamiento e infraestructura, causando la degradación de la imagen urbana, limitando el correcto desenvolvimiento de las actividades recreacionales y causando la pérdida de espacios públicos que permitan una integración socio cultural de la población. En la actualidad, se ha destinado un espacio a los márgenes del río Yunganza para la proyección de El Parque de la Juventud. La recuperación de este espacio como un lugar de esparcimiento, es necesaria para generar un proyecto que integre el contexto natural y edificado de la ciudad, con el fin de promover las actividades recreativas y evitar la degradación del paisaje y su imagen urbana.

Caffeine ingestion and cycling power output in a low or normal muscle glycogen state

Purpose Commencing selected workouts with low muscle glycogen availability augments several markers of training adaptation compared with undertaking the same sessions with normal glycogen content. However, low glycogen availability reduces the capacity to perform high-intensity (>85% of peak aerobic power (V·O2peak)) endurance exercise. We determined whether a low dose of caffeine could partially rescue the reduction in maximal self-selected power output observed when individuals commenced high-intensity interval training with low (LOW) compared with normal (NORM) glycogen availability. Methods Twelve endurance-trained cyclists/triathletes performed four experimental trials using a double-blind Latin square design. Muscle glycogen content was manipulated via exercise–diet interventions so that two experimental trials were commenced with LOW and two with NORM muscle glycogen availability. Sixty minutes before an experimental trial, subjects ingested a capsule containing anhydrous caffeine (CAFF, 3 mg-1·kg-1 body mass) or placebo (PLBO). Instantaneous power output was measured throughout high-intensity interval training (8 × 5-min bouts at maximum self-selected intensity with 1-min recovery). Results There were significant main effects for both preexercise glycogen content and caffeine ingestion on power output. LOW reduced power output by approximately 8% compared with NORM (P < 0.01), whereas caffeine increased power output by 2.8% and 3.5% for NORM and LOW, respectively, (P < 0.01). Conclusion We conclude that caffeine enhanced power output independently of muscle glycogen concentration but could not fully restore power output to levels commensurate with that when subjects commenced exercise with normal glycogen availability. However, the reported increase in power output does provide a likely performance benefit and may provide a means to further enhance the already augmented training response observed when selected sessions are commenced with reduced muscle glycogen availability. It has long been known that endurance training induces a multitude of metabolic and morphological adaptations that improve the resistance of the trained musculature to fatigue and enhance endurance capacity and/or exercise performance (13). Accumulating evidence now suggests that many of these adaptations can be modified by nutrient availability (9–11,21). Growing evidence suggests that training with reduced muscle glycogen using a “train twice every second day” compared with a more traditional “train once daily” approach can enhance the acute training response (29) and markers representative of endurance training adaptation after short-term (3–10 wk) training interventions (8,16,30). Of note is that the superior training adaptation in these previous studies was attained despite a reduction in maximal self-selected power output (16,30). The most obvious factor underlying the reduced intensity during a second training bout is the reduction in muscle glycogen availability. However, there is also the possibility that other metabolic and/or neural factors may be responsible for the power drop-off observed when two exercise bouts are performed in close proximity. Regardless of the precise mechanism(s), there remains the intriguing possibility that the magnitude of training adaptation previously reported in the face of a reduced training intensity (Hulston et al. (16) and Yeo et al.) might be further augmented, and/or other aspects of the training stimulus better preserved, if power output was not compromised. Caffeine ingestion is a possible strategy that might “rescue” the aforementioned reduction in power output that occurs when individuals commence high-intensity interval training (HIT) with low compared with normal glycogen availability. Recent evidence suggests that, at least in endurance-based events, the maximal benefits of caffeine are seen at small to moderate (2–3 mg·kg-1 body mass (BM)) doses (for reviews, see Refs. (3,24)). Accordingly, in this study, we aimed to determine the effect of a low dose of caffeine (3 mg·kg-1 BM) on maximal self-selected power output during HIT commenced with either normal (NORM) or low (LOW) muscle glycogen availability. We hypothesized that even under conditions of low glycogen availability, caffeine would increase maximal self-selected power output and thereby partially rescue the reduction in training intensity observed when individuals commence HIT with low glycogen availability.

Contraction-induced changes in TNFα and Akt-mediated signalling are associated with increased myofibrillar protein in rat skeletal muscle

Resistance training results in skeletal muscle hypertrophy, but the molecular signalling mechanisms responsible for this altered phenotype are incompletely understood. We used a resistance training (RT) protocol consisting of three sessions [day 1 (d1), day 3 (d3), day 5 (d5)] separated by 48 h recovery (squat exercise, 4 sets × 10 repetitions, 3 min recovery) to determine early signalling responses to RT in rodent skeletal muscle. Six animals per group were killed 3 h after each resistance training session and 24 and 48 h after the last training session (d5). There was a robust increase in TNF? protein expression, and IKKSer180/181 and p38MAPK Thr180/Tyr182 phosphorylation on d1 (P < 0.05), which abated with subsequent RT, returning to control levels by d5 for TNF? and IKK Ser180/181. There was a trend for a decrease in MuRF-1 protein expression, 48 h following d5 of training (P = 0.08). Notably, muscle myofibrillar protein concentration was elevated compared to control 24 and 48 h following RT (P < 0.05). AktSer473 and mTORSer2448 phosphorylation were unchanged throughout RT. Phosphorylation of p70S6k Thr389 increased 3 h post-exercise on d1, d3 and d5 (P < 0.05), whilst phosphorylation of S6Ser235/236 increased on d1 and d3 (P < 0.05). Our results show a rapid attenuation of inflammatory signalling with repeated bouts of resistance exercise, concomitant with summation in translation initiation signalling in skeletal muscle. Indeed, the cumulative effect of these signalling events was associated with myofibrillar protein accretion, which likely contributes to the early adaptations in response to resistance training overload in the skeletal muscle.

Efecto de la edad de destete y del sistema de alimentación sobre el crecimiento en terneras de lechería

Se efectuó una prueba de alimentación usando el diseño de parcela dividida con un arreglo completamente al azar, con 36 terneras provenientes del cruce Holstein y Pardo Suizo, para comparar el efecto de dos edades de destete 4 y 8 semanas, y tres sistemas de alimentación en el crecimiento de terneras de lecheria. Los tratamientos fueron los siguientes: a) leche integra suministrada en forma gradual y el destete a las 4 semanas; b) leche integra suministrada en forma constante y el destete a las 4 semanas; c) sustituto de leche por 4 semanas; d, e y f, similares a los tratamientos anteriores en lo referente al alimento liquido pero con destete a las 8 semanas. El resto de la racion consistio en alimentos concentrados; iniciador, desarrollo y heno. Desde las 9 a las 20 semanas las terneras pasaron en grupos de seis a corrales comunes. El iniciador suministrado a las terneras de los tratamientos a y d se ofreció a razón de 144 gr. por litro de leche integra, previa disolución en agua, y el iniciador que consumieron las terneras de los tratamientos c y f se administro a razón de 0.90 kg hasta el destete. El concentrado de desarrollo se ofreció a los tratamientos a, b, d y a donde la 1 a las 20 semanas y en los tratamientos c y f después del destete hasta alcanzar un máximo de 2.7 kg. Todos los tratamientos tuvieron a disposición a partir del destete heno de estrella (Cynodon sp). La ganancia de peso vivo promedio total, de 66.48 kg obtenida por las terneras del tratamiento e, fue similar a las de 56.84, 50.74, 53.72 y 55.53 kg logradas por las terneras de los tratamientos b, c,d y f, pero significativamente diferente (P<0.05), a 43.42 kg alcanzada por las terneras del tratamiento a. El promedio de ganancias de peso vivo por día desde la 1 hasta las 20 semanas de edad fue 0.31, 0.41, 0.36, 0.38, 0.47 y 0.40 kg para los tratamientos a al f respectivamente. La mayor ganancia promedio en altura a la cruz 20.32 cm lograda por las terneras del tratamiento II fue similar a la de 17.97 cm obtenida por las terneras del tratamiento III, pero significativamente diferentes (P<0.01), con la de 15.94 cm alcanzada por las terneras del sistema I. El promedio de ganancia en perímetro toraxico fue 22.23, 27.30, 26.29, 26.29, 30.35 y 26.29 cm para los tratamientos a al f respectivamente. Estas ganancias no fueron significativas (P<0.05). Los costos totales de alimentación por ternera desde la 1 hasta las 20 semanas fueron 245.98, 315.74, 283.41, 318.41, 457.48 y 335.33 córdobas para los tratamientos a al f respectivamente. Los costos correspondientes por kg de aumento en peso vivo, fueron 5.67, 5.55, 5.59, 5.93, 6.88 y 6.04 respectivamente.

The content of the form of Julia Alvarezs In the time of the butterflies

In the Time of the Butterflies é um romance da escritora dominicana-americana Julia Alvarez sobre a vida e a morte das Borboletas, Las Mariposas, codinome das irmãs Mirabal, membros de um movimento clandestino contra o regime ditatorial de Rafael Leonidas Trujillo na República Dominicana, que se tornaram símbolos da luta contra o Trujillato depois de serem assassinadas a mando do ditador. Essa dissertação tem como objetivo expor como forma literária e contexto social estão diretamente relacionados nesse romance. Ela defende a ideia de que o borramento de três gêneros literários distintos metaficção historiográfica, autobiografia e bildungsroman reflete o questionamento das fronteiras entre o privado e o público, o pessoal e o político, o eu e o outro, o individual e o coletivo, a literatura e a história, fato e ficção e história e subjetividade. Ela também tenta mostrar como a problematização dessas dicotomias implica na contestação de noções pré-concebidas de identidade, história e nação
