Authors: Mesa Tejeda Natacha Teresa , Hernández Atienza María Karla
Published: December 2017

En el presente trabajo se realiza un análisis de la normativa jurídica que regula lo relativo al régimen jurídico de solución de conflictos en las cooperativas no agropecuarias en Cuba. EL Decreto Ley 305/12 «De las Cooperativas no Agropecuarias» así como el Decreto 309/12 «Reglamento de las Cooperativas de Primer Grado» están marcados por deficiencias técnicas y de redacción que vuelven poco probable la eficacia y realización práctica de los preceptos regulados en esas normas y en consecuencia, pueden comprometer el acceso a la justicia de los cooperativistas ante la existencia de conflictos entre ellos o entre ellos y la cooperativa.Recibido: 28 junio 2017Aceptado: 14 octubre 2017Publicación en línea: 22 diciembre 2017

Authors: Ross Ratchneewan , Shahrour Ghada , Stidham Andrea Warner , Delahanty Douglas
Published: December 2017

Background and Purpose: The World Health Organization Quality of Life BREF (WHOQOL-BREF) has been used in various populations and cultures. However, its psychometric properties are unknown among women who experienced intimate partner violence (WIPV). This study aimed to explore the reliability and validity of the WHOQOL-BREF among Thai WIPV. Methods: Two hundred eighty-four female patients receiving care at a northeast hospital in Thailand responded to the WHOQOL-BREF and intimate partner violence (IPV) questions. Exploratory factor and consistency analyses were applied. Results: Different from the original study, this study generated 5 factors, 1 of which is Medical Care Needs. The resulting scale and subscales showed good reliability and construct validity. Conclusion: The 5-factor scale can be used among WIPV by health care professionals to assess their quality of life (QOL) and appropriately address their needs.

Published: December 2017

Background and Purpose: Globally, depressive symptoms are a leading contributor to years lived with disability. The Center for Epidemiological Studies–Depression (CES-D) scale has been used extensively to quantify depression; yet, its psychometric properties remain contentious. This study examined the reliability and factor structure of the CES-D in the MacArthur Foundation’s Midlife in the United States Study (MIDUS), a nationally representative cohort study of noninstitutionalized, English-speaking adults aged 24–74 years. Methods: Internal consistency (Cronbach’s alpha) and confirmatory factor analysis (CFA) were used to examine the reliability and factor structure of the CES-D. Results: There were 1,233 participants who were included in the analysis (mean age = 57.3 years [SD = 11.5], 56.7% female). Cronbach’s alpha of .90 was observed. The 4-factor model had the best model fit. Conclusions: High internal consistency was demonstrated alongside a replication of the original 4-factor structure. Continued use of the CES-D in noninstitutionalized populations is warranted.

Obtention of Cellulose Acetate Nanofibers From Sugar Cane Bagasse
Authors: Muñoz Prieto Efren De Jesus
Published: December 2017

Cellulose is one of the oldest natural polymers, it is renewable, biodegradable, and can be derivatized to manufacture useful products. The electrospinning, a technique for the manufacture of nanofibers, has garnered attention in recent years due to its versatility and potential for applications in various fields such as biomedicine, tissue engineering andalso filtration. In this study, cellulose acetate fibers have been obtained by electrospinning. To achieve these results, the cellulose was initially obtained from the sugar-cane bagasse of local plantations in Moniquira, Boyaca, then cellulose was modified to obtain cellulose acetate, which has enhanced properties for electrospinning. Yarn parameters were determined, such as needle-manifold distance, flow rate, voltage and polymer concentration, among others. Instrumentalanalyses were carried out including Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA). As a result, cellulose acetate fibers were obtained with an average diameter of 258 nm, with excellent properties such as temperature resistance. This was done in order to continue the work on nanofiber functionalization, as for example, cationization of cellulose and further addition ofreactive dyes.

Authors: Garcia Ivan Supelano , Sarmiento Santos Armando , Soto Erika
Published: December 2017

La tecnología del plasma es una ciencia que desde sus comienzos se encuentra en una constante evolución, desde aplicaciones para el tratamiento de materiales hasta aplicaciones ambientales. En particular el plasma de la descarga luminiscente ofrece una amplia gama de aplicaciones desde aplicaciones en plasmo-química hasta tratamientos termoquímicos de materiales. En el presente trabajo se busca aprovechar la generación de calor por parte de la descarga luminiscente de baja presión en corriente continua, debido a la transferencia de energía cinética desde el plasma hacia los electrodos. Para ello se diseñó un reactor cilíndrico que genera una descarga luminiscente de baja presión en una atmósfera de argón. El cátodo de la descarga lo constituye el electrodo interno, mientras que el ánodo, y al mismo tiempo la pared de la cámara, lo constituye un cilindro metálico externo, concéntrico al cátodo. Para mantener la descarga se utilizó una fuente de corriente continua pulsada y la descarga se generó a varias corrientes y en diferentes atmósferas gaseosas ($N_{2}$, $H_{2}$ y $Ar$). Mediante medidas eléctricas de la descarga se determinó la potencia y consumo energético del reactor, comparándolo con los valores obtenidos para un dispositivo calefactor comercial basado en resistencias eléctricas.

Published: December 2017

In order to coordinate the damping performance and energy regenerative performance of energy regenerative suspension, this paper proposes a structure of vehicle semi-active energy regenerative suspension with electro-hydraulic actuator (EHA). In light of the proposed concept, a specific energy regenerative scheme is designed and the mechanical properties test is carried out. Based on the test results, the parameter identification for the system model is conducted using recursive least squares algorithm. On the basis of system principle, the nonlinear model of the semi-active energy regenerative suspension with EHA is built. Meanwhile, LQG control strategy of the system is designed. And then the influence of the main parameters of EHA on the damping performance and energy regenerative performance of suspension is analyzed. Finally, the main parameters of EHA actuator are optimized via genetic algorithm. The test results show that when sinusoidal is input at the frequency of 2Hz and the amplitude of 30mm, the spring mass acceleration RMS value of optimized EHA semi-active energy regenerative suspension is reduced by 22.23% and energy regenerative power RMS value is increased by 40.51%, which means while meeting the requirements of certain vehicle ride comfort and driving safety, energy regenerative performance is improved significantly.

Indonesia is one of the largest suppliers of informal labor in developed countries in ASEAN, Hongkong, Korea, Japan and Middle East Countries. Unlike the formal workforce that has good protection and income certainty. Workers in the non-formal sector still have vulnerabilities to get problems so there are efforts to reduce and prevent more Indonesians from becoming workers in the informal sector. One strategy is to increase the potential of migrant workers not to go abroad and to prevent ex-migrant workers from returning abroad.How to prevent good is to train the former migrant workers by sharing skills so that they can develop their business independently. The training developed is to train entrepreneurial character and practice business skills. Community service is expected to help the program. Community service activities for former migrant workers are conducted in the form of entrepreneurship training. In this activity the participants are former TKI in Sukabumi which amounted to 20 people, conducted in Cibolang Village Gunung Guruh District.

Objetivo. Evaluar la prevalencia de anticuerpos antiparotidi­tis en niños y adolescentes de México, a dos años de haberse introducido la vacuna SRP. Material y métodos. Se estu­diaron 2 111 niños (1-9 años) y 2 484 adolescentes (10-19 años). Se evaluaron anticuerpos IgG con un kit comercial de ELISA indirecto. Resultados. La seroprevalencia fue 70.6% (IC95% 69.3-71.9) y resultó mayor en adolescentes (83.0%, IC95% 81.5-84.5) que en niños (56.0%, IC95% 53.9-58.11) (OR 3.83; IC95% 3.34-4.39, p=0.0000000). Los niños de 1 a 2 y de 6 a 9 años, que a partir de 1998 formaron parte del grupo blanco de vacunación vs parotiditis, tuvieron mayor seroprevalencia que el grupo de 3 a 5 años no vacunado. Conclusiones. La seropositividad en niños de 1 a 2 y de 6 a 9 años fue probablemente atribuible a vacunación durante 1998-2000 y la de otros grupos etarios a exposición natural relacionada con el tiempo transcurrido en cada cohorte de nacimientos hasta el reclutamiento al estudio

Published: December 2017

The combustion characteristics of textile dyeing sludge (TDS) in N2/O2, CO2/O2, and N2/CO2 atmospheres, and blends of TDS with coal were analyzed using TGA (thermogravimetric analysis). Results showed that the replacement of N2 by CO2 resulted in negative effects on the combustion and pyrolysis of TDS. Comparing N2/O2 and CO2/O2 atmospheres, combustion of TDS was easier in a N2/O2 atmosphere, but the residual mass after TDS pyrolysis in pure CO2 was less than that in N2 by approximately 4.51%. When the proportion of TDS was 30–50% in the blends of coal with TDS, a synergistic interaction clearly occurred, and it significantly promoted combustion. In considering different combustion parameters, the optimal proportion of TDS may be between 20–30%. The activation energy Ea value decreased from 155.6 kJ/mol to 53.35 kJ/mol with an increasing TDS proportion from 0% to 50%, and it rapidly decreased when the TDS proportion was below 20%.

Authors: Li Zhongtian , Stenstrom Michael K.
Published: December 2017

Particle size distribution of the particulates is an essential characteristic of the wastewater quality. Particle size of activated sludge flocs may affect key sludge handling processes including sedimentation, thickening, digestion, and dewatering. This study evaluated the effects of solids retention time (SRT) on particle size distribution, sludge settleability, effluent turbidity, and removals of chemical oxygen demand (COD) and ‐N in a lab‐scale Modified Ludzak–Ettinger (MLE) reactor and an integrated fixed film activated sludge (IFAS) reactor. This study also surveyed particle size distribution profile of five full‐scale water resource recovery facilities (WRRFs), including high purity oxygen (HPO), step‐feed nitrification/denitrification (NDN), and MLE NDN processes. This study provides direct evidence of the effects of SRT on particle size distribution and sludge settleability in lab‐scale reactors and full‐scale WRRFs.

AbstractThe photoluminescence of a nonequilibrium polariton condensate in cylindrical and rectangular micropillars etched on the surface of a high- Q GaAs microcavity is investigated in magnetic fields of up to 12 T. The measurements are carried out under different levels of nonresonant optical pumping with nanosecond laser pulses for a wide range of cavity detuning. As far as nonresonant excitation produces a high density of excitons in a reservoir, it should be expected that the exciton–polariton interaction, which depends on the pump level, has a considerable effect on the Zeeman splitting and polarization of the condensate. However, measurements of the Zeeman splitting and polarization in high magnetic fields demonstrate that only minor changes take place up to the highest available pump levels. This means that, in the case under study, the effect of exciton–polariton interaction on the polariton system is insignificant. At the same time, the data obtained provide an estimate for the exciton density in the reservoir. In contrast to cylindrical micropillars, the photoluminescence of the condensate in rectangular micropillars consists of two perpendicularly linearly polarized lines which retain a high degree of linear polarization even in a field as high as 12 T. The Zeeman splitting in this case is nearly independent of the pump power. The degrees of both circular and linear polarization change with pump power, but these changes are noticeably smaller than the ones predicted theoretically. This indicates that the system of polaritons in micropillars deviates considerably from thermodynamic equilibrium.

AbstractThe quasi-mobility function of charge carriers with a specified energy for describing their dynamics using the kinetic equation is studied in the important case of two-term isotropic approximation. In the stationary case, the quasi-mobility function is independent of the source function of charge carriers and makes it possible to calculate the integral mobility. The correlation between the quasi-mobility and parameters of the system is analyzed. It is proved that this characteristic does not generally describe the contribution of charge carriers with a specified energy to the integral mobility. In the case of almost elastic scattering, the quasi-mobility, as is known, can have a clear physical meaning; however, in the case of the scattering of charge carriers at acoustic phonons in a solid, this quasi-mobility interpretation is found to be incorrect due to the specific features of the collision integral and the form of the quasi-mobility function.

AbstractHybrid quantum-confined heterostructures grown by metal-organic vapor-phase epitaxy (MOVPE) via the deposition of In_0.4Ga_0.6As layers with various nominal thicknesses onto vicinal GaAs substrates are studied by photoluminescence spectroscopy and transmission electron microscopy. The photoluminescence spectra of these structures show the superposition of two spectral lines, which is indicative of the bimodal distribution of the size and/or shape of light-emitting objects in an array. The dominant spectral line is attributed to the luminescence of hybrid “quantum well–dot” nanostructures in the form of a dense array of relatively small quantum dots (QDs) with weak electron and hole localization. The second, lower intensity line is attributed to luminescence from a less dense array of comparatively larger QDs. Analysis of the behavior of the spectral line intensities at various temperatures showed that the density of larger QDs grows with increasing thickness of the InGaAs layer.

AbstractX-ray diffraction and differential thermal analysis data obtained in the Cu_1.95Ni_0.05S phase-transition region are analyzed. It is established that the low-temperature rhombic α phase in Cu_1.95Ni_0.05S transforms to the hexagonal β phase at temperatures of 370–390 K and to the cubic γ phase at temperatures of 740–765 K according to the scheme $$\alpha \to \mathop {\alpha + \beta }\limits_{370 - 390K} \to \mathop {\alpha + \gamma }\limits_{740 - 765K} \to \gamma $$ α → α + β 370 − 390 K → α + γ 740 − 765 K → γ . It is determined (using the temperature dependence of differential thermal analysis) that the transition α → β is accompanied by heat absorption while the transition β → γ is accompanied by heat release. It is found that both transitions are allowed and belong to the reconstructive type. Both transitions are found to occur in a fluctuation volume of ~10^–20 cm^3 at temperature rates of 0.11 and 0.08 K^–1. It is demonstrated that the transition α → γ is accompanied by alternation of the structures passing through the intermediate β phase, which is incommensurate with respect to the α and γ phases.

AbstractThe conditions under which the thermodynamic theory of the critical slowing-down of the order parameter relaxation rate describes the behavior of magnetically uniaxial crystals are formulated. Taking into account the formulated conditions, the peculiarities of the dynamic magnetic susceptibility and the critical slowing-down of the magnetization relaxation rate of PbFe_12O_19 in the vicinity of the Curie temperature are studied. The obtained experimental results agree well with the droplet model of phase transitions. Based on the experimental data, an estimated value of the correlation length for the magnetization in the temperature area of the critical slowing-down of the relaxation rate is obtained within the droplet model.

AbstractNonempirical equations of state of compressed rare gas crystals Ne, Ar, Kr, and Xe are studied on the basis of the earlier-obtained ab initio adiabatic potential. The paired and three-body short-range repulsive potentials are calculated by the Hartree–Fock method in the basis of localized functions with their exact mutual orthogonalization and do not contain experimentally determined parameters. The theory is compared with the experiment and results of calculations by other authors. Analysis of the proposed equations of state for large compressions has shown the importance of taking into account the three-body interaction and the terms of the higher order in the overlap integral in compressed neon and the sufficiency of the quadratic approximation in the orthogonalization of functions in heavy rare gas crystals.

AbstractWe propose a method of estimating spectral properties of a system from short signals and processes with varying characteristics, which is based on the wavelet-transform modulus-maxima method. It is shown that this approach allows significant reduction of the computing error as compared with the classical spectral analysis.

AbstractAn electron beam with a high (close to 100%) coefficient of electron capture into the regime of acceleration has been obtained in a linear electron accelerator based on a parallel coupled slow-wave structure, electron gun with microwave-controlled injection current, and permanent-magnet beam-focusing system. The high capture coefficient was due to the properties of the accelerating structure, beam-focusing system, and electron-injection system. Main characteristics of the proposed systems are presented.

AbstractThe solar-energy conversion in eosin-sensitized solar cells based on cobalt and yttrium modified TiO2 nanotubes has been studied.It is established that the doping with metal ions shifts the absorption edge for Co and Y doped titanium dioxide samples to longer and shorter wavelengths, respectively. The efficiency of solar energy conversion depends on the wide bandgap of the semiconductor anode and reaches a maximum (4.4%) for yttrium-doped TiO_2 in comparison to that (4.1%) for pure titanium dioxide.

AbstractPossible mechanisms of the interfacial interaction in multiperiodic (bilayer) compositions at critical thicknesses (as small as below 10 nm) of conjugated phases have been studied for the first time using structure analysis, numerical simulations, and measurements of mechanical characteristics. For attaining a state of superhigh hardness (above 40 GPa), it is proposed to form coatings with variable layer thicknesses in the bilayer period Λ. Using this approach, 10-μm-thick coatings of the TiN/ZrN system with hardness above 44 GPa were obtained for a bilayer period of Λ ≈ 10 nm with a layer thickness ratio of 1.5/1.

AbstractConditions of the excitation of toroidal Alfvén eigenmodes (TAEs) and their inf luence on the confinement of fast particles into the Globus-M spherical tokamak have been studied by KINX code calculations of the magnetohydrodynamic spectra of reconstructed divertor equilibrium configurations with stability margin q _0 > 1 on the magnetic axis. The sensitivity of the frequencies of TAE modes with toroidal wavenumber n = 1 to the type of boundary conditions and choice of boundary surface has been studied. It has been established that the frequencies of modes with dominating poloidal harmonics m = 1 and 2 in the gap of continuum are significantly higher than those observed in the spectra of signals measured in the Mirnov coil probes, especially under the assumption of free plasma boundary with allowance for its compressibility. The TAE modes with lower frequencies and higher poloidal wavenumbers localized near the plasma boundary may be responsible for the oscillations observed in the experiment. However, these modes are characterized by the interaction with continuum and, probably, exhibit related damping.

AbstractResults of studying nanocrystalline nc-Si/SiO_2 quantum dots (QDs) functionalized by short oligonucleotides show that complexes of isolated crystalline semiconductor QDs are unique objects for detecting the manifestation of new quantum confinement phenomena. It is established that narrow lines observed in high-resolution spectra of inelastic light scattering can be used for determining the characteristic time scale of vibrational excitations of separate nucleotide molecules and for studying structural-dynamic properties of fast oscillatory processes in biomacromolecules.
Interrogating ‘Absolute Discretion’: Are Nz's Parliament and Courts Compromising the Rule of Law?
Authors: Wilberg Hanna
Published: December 2017

It is elementary in administrative law that there is no such thing as unfettered discretion–yet, in a development that appears to have gone largely unnoticed, statutes increasingly confer ‘absolute discretion’ on public decision-makers. This article explores and evaluates these provisions and their judicial treatment in New Zealand. It surveys the range of contexts in which they are used and the various purposes or functions they appear to serve, and evaluates each against orthodoxy. It also surveys the judicial responses to such provisions, finding that these are mixed and too often muted. Of particular concern are the ‘absolute discretion’ provisions in the Immigration Act, and the lack of a consistently resolute judicial response to these.
Interseccionalidade em educação e saúde: o livro Cenários da Saúde da População Negra no Brasil - Diálogos e Pesquisas, 2016
Authors: De Souza Lucia Ferraz Varges
Published: December 2017

A saúde e a educação são campos que se esbarram no fazer cotidiano dos profissionais que atuam com seres humanos. A relação destes dois campos deve ser de equilíbrio e harmonia tanto no campo do trabalho de professores, como no trabalho de profissionais médicos, psicólogos, enfermeiros, enfim. O campo da pesquisa raramente consegue agregar com harmonia esta necessidade de interseccionalidade em saúde e educação. Diante desta realidade, o livro “Cenários da saúde da população negra no Brasil – diálogos e pesquisas” possui esta qualidade e agrega pesquisa em saúde e reflexões para profissionais que atuam nas escolas, no SUS, no SUAS, nas associações e instituições comunitárias.  O livro apresenta os sujeitos negros em suas vidas cotidianas com o olhar da pesquisa acadêmica que serve as necessidades do Brasil negro e indígena.

THE NIGHT IS DARKEST JUST BEFORE THE DAWN: BATMAN E GOTHAM
Authors: Duarte José
Published: December 2017

Desde a sua criação em 1939 que Batman teve diferentes representações. O mesmo acontece com a cidade que o acolhe: Gotham, pois ambos são indissociáveis. As várias transformações ocorridas quer no protagonista principal, quer na cidade, são particularmente notórias nas inúmeras adaptações televisivas/cinematográficas feitas ao longo do tempo. Desde a década de 40 do século XX, passando pela série dos anos 60, até às adaptações de Burton, Schumacher ou, mais recentemente, à trilogia de Christopher Nolan, Batman e Gotham sofreram transformações que são produtos do seu tempo. O presente estudo pretende apresentar uma breve reflexão sobre algumas destas adaptações, com especial atenção à relação do protagonista principal com a cidade. Neste sentido, será dada especial ênfase aos três últimos filmes que exploram, de modo bastante evidente, os acontecimentos resultantes dos ataques terroristas do 11 de Setembro de 2001 e as suas consequências. Assim, este ensaio divide-se em dois momentos essenciais. Num primeiro momento, será estabelecida a relação entre Batman e Gotham (entre corpo e cidade) e será apresentada uma breve leitura desta relação considerando algumas adaptações chave nas décadas seguintes ao aparecimento do super-herói. Numa segunda fase, é feita uma análise da trilogia de Nolan, tendo em conta os aspectos acima mencionados. Deste modo, a breve reflexão aqui apresentada tentará focar-se na evolução e simbologia de Gotham e Batman ao longo do tempo.
UNCANNY NORTH AMERICA IN CONTEMPORARY HORROR FILMS: AMERICAN MARY, MANIAC, AND THE INVITATION
Authors: Hendershot Cyndy
Published: December 2017

This article examines contemporary examples of the uncanny in horror films from North America. Three films are analyzed: American Mary (2012), Maniac (2012), and The Invitation (2015). These three films use the uncanny to examine contemporary issues, such as body-modification surgery and murder/suicide cults. Thus, the films utilize a familiar method to invoke the feeling of the uncanny in the viewer while dealing with tropes not common to the horror genre. These three independent films invoke feelings of unease without the use of common tropes of the genre, such as vampires and zombies. The methodology employed is a Freudian critical theory base to look at the manner in which contemporary horror films employ the idea of the uncanny to address contemporary issues. While Freud himself developed the idea of the uncanny utilizing works contemporary to his time, most especially E.T.A. Hoffman’s “The Sandman,” his theory applies to works of horror decades later. For example, the trope of dolls, which is key to Freud’s argument in “The Uncanny” (1919), still produces the same feeling in the audience nearly one hundred years later. The conclusion is that Freudian theory remains a viable method to examine horror films.
CIDADE MARAVILHOSA: EXPLORAÇÃO DOS SENTIDOS DE UMA METONÍMIA
Authors: Xavier Priscilla
Published: December 2017

O presente artigo propõe uma possibilidade de compreensão da dinâmica do dizer a cidade. Considerando o dizer um fenômeno social, pretendemos exercitar uma análise de discurso, que toma o termo “Cidade Maravilhosa” como uma metonímia do Rio de Janeiro, admitindo em tal dizer um teor dinâmico. Buscamos apreender a dinâmica da “Cidade Maravilhosa” a partir de uma analogia ao caleidoscópio, produzindo imagens de conjunturas, organizando e expondo conteúdos relevantes e eloquentes para compreensão dos sentidos dos discursos. Nesse caleidoscópio três superfícies espelhadas refletem objetos que, em movimento, produzem imagens sucessivas, entre possibilidades de combinações inúmeras. A política, a cultura e o urbanismo serão os espelhos e as narrativas acerca da Cidade Maravilhosa os objetos em movimento que serão refletidos. A imagem do Rio de Janeiro será composta por conjunturas institucionais distintas, sejam elas o Rio de Janeiro como capital da república, Estado da Guanabara e Rio de Janeiro pós-fusão. O resultado é a percepção da mudança dos conteúdos que conferem sentido aos discursos sobre o Rio de Janeiro, no que tange o imaginário e as disputas de poder expressas ou inspiradas na Cidade Maravilhosa.
Entrepreneurship Opportunities
Authors: Sigala Marianna , Dolnicar Sara
Published: December 2017

This chapter explores entrepreneurship opportunities resulting from the emergence of peer-to-peer trading. Opportunities range from high risk – like the establishment of an entirely new peer-to-peer trading platform – to very low risk – like a local window cleaner picking up additional business from peer-to-peer accommodation network hosts. The unusual aspect of those opportunities is that they: (1) mostly represent opportunities for micro-entrepreneurs potentially opening new avenues for earning money to people who have difficulties finding permanent employment (see Chapter 14); and (2) have the potential to strengthen local economies of rural and regional areas.

Airbnb was born around an event. The founders of Airbnb offered inflatable mattresses and breakfast to conference attendees in San Francisco who could not find a place to stay. Airbnb launched at the 2008 Democratic National Convention where attendees with unused space in their homes hosted attendees unable to find commercial accommodation. Airbnb was conceived and born around events. This chapter explores the role peer-to-peer accommodation networks can play in the context of both large, international events and small rural and regional events.
