Cost-effective and eco-friendly synthesis of novel and stable N-doped ZnO/g-C3N4 core-shell nanoplates with excellent visible-light responsive photocatalysis

N-doped ZnO/g-C3N4 hybrid core–shell nanoplates have been successfully prepared via a facile, cost-effective and eco-friendly ultrasonic dispersion method for the first time. HRTEM studies confirm the formation of the N-doped ZnO/g-C3N4 hybrid core–shell nanoplates with an average diameter of 50 nm and the g-C3N4 shell thickness can be tuned by varying the content of loaded g-C3N4. The direct contact of the N-doped ZnO surface and g-C3N4 shell without any adhesive interlayer introduced a new carbon energy level in the N-doped ZnO band gap and thereby effectively lowered the band gap energy. Consequently, the as-prepared hybrid core–shell nanoplates showed a greatly enhanced visible-light photocatalysis for the degradation of Rhodamine B compare to that of pure N-doped ZnO surface and g-C3N4. Based on the experimental results, a proposed mechanism for the N-doped ZnO/g-C3N4 photocatalyst was discussed. Interestingly, the hybrid core–shell nanoplates possess high photostability. The improved photocatalytic performance is due to a synergistic effect at the interface of the N-doped ZnO and g-C3N4 including large surface-exposure area, energy band structure and enhanced charge-separation properties. Significantly, the enhanced performance also demonstrates the importance of evaluating new core–shell composite photocatalysts with g-C3N4 as shell material.

Template-free and eco-friendly synthesis of hierarchical Ag3PO4 microcrystals with sharp corners and edges for enhanced photocatalytic activity under visible light

Herein, we demonstrate a template-free and eco-friendly strategy to synthesize hierarchical Ag3PO4 microcrystals with sharp corners and edges via silver–ammine complex at room temperature. The as-synthesized hierarchical Ag3PO4 microcrystals were characterized by X-ray diffraction, field-emission scanning electron microscope (FESEM), UV–vis diffuse reflectance spectroscopy (UV–vis DRS), BET surface area analyzer, and photoluminescence analysis (PL). Our results clearly indicated that the as-synthesized Ag3PO4 microcrystals possess a hierarchical structure with sharp corners and edges. More attractively, the adsorption ability and visible light photocatalytic activity of the as-synthesized hierarchical Ag3PO4 is much higher than that of conventional Ag3PO4.

Magyarországi „munkavállaló-barát” (employee friendly) szervezetek – Valóság vagy utópia (avagy mit tanulhatunk tőlük?) = The Hungarian employee friendly organizations: reality or Utopia (or what can we learn from them?)

A szerzők feltáró kutatásukban munkavállaló-barát szervezeti megoldásokat kerestek és vizsgáltak multiparadigmikus (Primecz, 2008) megközelítéssel, kritikai és funkcionalista szemszögből. Munkavállalóbarát szervezeti gyakorlatnak tekintették azokat a szervezeti kultúrában gyökerező szervezeti kereteket és gyakorlatokat, amelyek nagymértékben támogatják a munkavállalókat a munka és magánélet egyensúlyának elérésében és megtartásában (Toarniczky et al., 2011). Eredményeik szerint a munkavállaló-barát gyakorlatokat akkor értékelik legjobban a szervezeti tagok, ha a közvetlen vezető és kollégák jól értik a támogatandó munkavállaló helyzetét és rugalmasan fordítják le a hétköznapokra a HR-rendszereket. Ezzel együtt több feszültség keletkezik a szervezetben a munkavállaló-barát gyakorlatokban, amelyekre figyelni lehetne, anélkül, hogy a kialakított gyakorlatokat felszámolnák. _____ The authors in their research investigated employee friendly practices, which they defined as frameworks and practices rooted in organisational culture that gives maximum support for employees trying to reach and keep balance between work and private life (Toarniczky et al., 2011) through multiparadigm research (Primecz, 2008). They conducted exploratory research (interviews, focus groups, document-analysis, and questionnaire) at ten Hungarian-based organizations, and they investigated employee friendly work practices through functionalist and critical lenses. Their results shows that employee friendly practices work well, when the immediate boss and colleagues understand the need of organization al member, who are supported, and HR procedures are translated flexibly. At the same time tension within the organization al subgroups always present, and this should be handled by the organization without cancelling employee friendly practices.

The river, the railroad tracks, and the towers: How residents' worldview and use value transformed Wilton Manors into a diverse, gay-friendly, urban village

This case study examines the factors that shaped the identity and landscape of a small island-urban-village between the north and south forks of the Middle River and north of an urban area in Broward County, Florida. The purpose of the study is to understand how Wilton Manors was transformed from a “whites only” enclave to the contemporary upscale, diverse, and third gayest city in the U.S. by positing that a dichotomy for urban places exists between their exchange value as seen by Logan and Molotch and the use value produced through everyday activity according to Lefebvre. Qualitative methods were used to gather evidence for reaching conclusions about the relationship among the worldview of residents, the tension between exchange value and use value in the restructuration of the city, and the transformation of Wilton Manors at the end of the 1990s. Semi-structured, in-depth interviews were conducted with 21 contemporary participants. In addition, thirteen taped CDs of selected members of founding families, previously taped in the 1970s, were analyzed using a grounded theory approach. My findings indicate that Wilton Manors’ residents share a common worldview which incorporates social inclusion as a use value, and individual agency in the community. This shared worldview can be traced to selected city pioneers whose civic mindedness helped shape city identity and laid the foundation for future restructuration. Currently, residents’ quality of life reflected in the city’s use value is more significant than exchange value as a primary force in the decisions that are made about the city’s development. With innovative ideas, buildings emulating the new urban mixed-use design, and a reputation as the third gayest city in the United States, Wilton Manors reflects a worldview where residents protect use value as primary over market value in the decisions they make that shape their city but not without contestation.^

A profile of travelers who are willing to stay in environmentally friendly hotel

The purpose of this study is to describe travelers that have indicated they are willing to stay in green hotel in order to better understand the market segment. There is very little knowledge about these types of travelers, thus making it difficult for hoteliers to know how to create marketing campaigns that target them. Data were collected via an online survey company. Behavior characteristics provided a more distinguishing profile of the traveler than did demographics or psychographics. Most travelers were willing to pay the same amount for a green hotel as a traditional hotel. Implications, future research, and limitations are discussed.

Complexity as key to designing cognitive-friendly environments for older people

The lived environment is the arena where our cognitive skills, preferences, and attitudes come together to determine our ability to interact with the world. The mechanisms through which lived environments can benefit cognitive health in older age are yet to be fully understood. The existing literature suggests that environments which are perceived as stimulating, usable and aesthetically appealing can improve or facilitate cognitive performance both in young and older age. Importantly, optimal stimulation for cognition seems to depend on experiencing sufficiently stimulating environments while not too challenging. Environmental complexity is an important contributor to determining whether an environment provides such an optimal stimulation. The present paper reviews a selection of studies which have explored complexity in relation to perceptual load, environmental preference and perceived usability to propose a framework which explores direct and indirect environmental influences on cognition, and to understand these influences in relation to aging processes. We identify ways to define complexity at different environmental scales, going from micro low-level perceptual features of scenes, to design qualities of proximal environments (e.g., streets, neighborhoods), to broad geographical areas (i.e., natural vs. urban environments). We propose that studying complexity at these different scales will provide new insight into the design of cognitive-friendly environments.

Haematological and biochemical blood study in baby alpaca with diarrhoea

The aim of this study was to determine the haematological value and biochemical blood in baby alpacas with enteric disorder. A total of 30 blood and serum samples were collected from alpacas of 1 month old with diarrhoea and 5 blood samples of clinically healthy baby alpacas (controls). The animals were from communities in the central Andes from Peru. About haematology were determined haematocrit, haemoglobin concentration, red blood count and white blood count that were not significantly different between control animals and animals with diarrhoea. Moreover, biochemical blood parameters as total protein, albumin and calcium decrease significantly (p<0.05). We conclude that our results could be considered as factors in the mortality of baby alpaca by infectious diarrhoea.
