Abstract
Introduction Surveys of lift installations are required for many reasons. In some cases, the frequency of breakdowns and stoppages becomes so great that the occupants of the building require the cause to be established by an independent surveyor, who is unconnected with the lift company responsible for maintenance, or with the landlord. There is also the situation where, while there have been numerous breakdowns, the lift service is maintained overall, but with a consequently high maintenance premium, involving a steady stream of bills for repairs and replacement parts. In such cases, it is important to establish that the contractor's claims are justified and that he is not increasing his profits by preying on laymen's limited knowledge.

Abstract
This paper utilizes controversies over the role of a set of insecticides in mass honey bee die-offs in two different national contexts – France and the United States – in order to understand the science-state nexus in a comparative manner. On the one hand, the French government in 1999 and 2004 suspended the commercial use of the insecticidal products that beekeepers suspected of causing the honey bee declines. On the other hand, the US government has to date refused to heed beekeepers’ calls to limit the usage of the very same set of insecticides. We examine why the governments of France and the United States came to contrasting conclusions regarding broadly similar technoscientific issues. The divergent outcomes, we argue, are not simply the result of predetermined differences in the two states’ regulatory paradigms (with France being “precautionary,” and the United States adhering to a “sound science” approach), but are underpinned by divergent forms of beekeepers’ resistance. The paper further sheds light on non-state actors’ use of science and state to contest state (in)action by analyzing how historically influenced differences in state structures, the relational dynamics of beekeepers’ and farmers’ organizations, and the epistemic cultures of honey bee knowledge production, shaped different forms of resistance and influence in France and the United States.

Abstract
Purpose
The aim of this study was to produce an enriched honey powder with active compounds coming from bee pollen and investigate the effects of bee pollen addition as a carrier material on honey powder.
Design/methodology/approach
The effects of bee pollen addition as carrier material in corporation with gum arabic at different ratios (25, 50 and 75% of total carrier material amount) on vacuum-dried honey-bee pollen powder were investigated.
Findings
The bee pollen concentration raise in the mixture increased the particle size, total phenolic, flavonoid and sugar contents and antioxidant activity, whereas decreased the Hauser ratio and Carr index values, hygroscopicity and solubility of enriched honey powder samples. The honey powder samples had passable and poor flow properties and very hygroscopic (>20%) structure because of the high sugar content. The phenolic and flavonoid contents of honey powder samples with bee pollen changed between 1531.59 and 3796.00 mg GAE/kg and 424.05–1203.10 mg QE/kg, respectively, and these values were much higher than the control sample. On the basis of linear correlation analysis, there was a very high positive correlation between total phenolic, flavonoid and antioxidant activity, while there was a very high negative correlation between these parameters and solubility.
Originality/value
The study evaluated that enriching of honey powders with pollen, which is a product of both plant and bee origin, rather than enriching with different plant and animal sources has an innovative approach. Additionally, the usage of bee pollen as a carrier agent in food drying has not been previously reported in any study.

Abstract
Purpose
The purpose of this paper was to study the effect of botanical origin on the characteristics of single-flower honeys (assa-peixe, coffee, eucalyptus, laranjeira and vassourinha), polyfloral (silvestre), extrafloral (sugarcane) and honeydew (bracatinga) during storage.
Design/methodology/approach
The honeys were stored at 14 °C, and the analysis of water activity, color, absorbance, rheological behavior and microscopic analysis were performed during 6 months (T0, T30, T60, T90, T120, T150 and T180 days); quantification of sugars (fructose (F) and glucose (G)), moisture (M), F/G and G/M ratio only at T0.
Findings
All honeys showed changes during storage, and sugarcane honey stood out for presenting greater crystallization, influenced by the high content of glucose and fructose. Coffee honey showed the least crystallization. The crystallization of honeys influenced the increase in water activity, Newtonian viscosity, color and absorbance. The composition of the honeys directly influenced the crystallization process during storage.
Originality/value
Crystallization is a natural process that occurs spontaneously in honey. Thus, the knowledge of the crystallization rate of honeys from different origins (botanical and geographical) during storage, is of great importance and interest for the industry, beekeepers and consumers, since each type of honey crystallizes in different ways and periods.

Abstract
Purpose
Stirred yoghurt made using probiotic bacteria which are usually called Rayeb milk in the Arab countries is one of the most important functional fermented milk products. Tamr (dried dates) is commonly consumed in various parts of the world and is believed to represent a vital component of the diet in the Arab world. Tamr and honey characterize with high nutritional and healthful benefits. The purpose of this paper is to manufacture functional fermented dairy food (Rayeb milk) which has the nutritional and health effects of goat’s milk, Tamr, honey and probiotic.
Design/methodology/approach
Rayeb milk was made from goat’s milk fortified with Tamr (10 and 15 percent) with or without honey (1, 2, and 3 percent) using ABT culture (S. thermophiles, L. acidophilus, and Bifidobacterium). Samples of Rayeb milk were studied for their chemical composition, starter bacteria populations, and sensory attributes during 14 days of storage period.
Findings
Supplementation of goat’s milk with Tamr and honey decreased saturated fatty acids concentrations in Rayeb milk. The levels of carbohydrate, total solids, dietary fiber, ash, total protein (TP), unsaturated fatty acids, omega-3, omega-6, omega-9 fatty acids and antioxidants activity were higher in Rayeb milk contained Tamr and honey than those of control. Also, numbers of probiotic bacteria (L. acidophilus and Bifidobacterium) greatly increased in Rayeb milk supplemented with Tamr and honey. The recommended level of 107 cfu.g-1 of bifidobacteria as a probiotic was exceeded for these treatments. Adding Tamr and honey highly improved the sensory attributes of Rayeb milk.
Originality/value
Adding 10 percent Tamr with 3 percent honey or 15 percent Tamr with 1 or 2 percent honey to goat’s milk highly improved the nutritional, healthy and sensory properties of Rayeb milk.

Abstract
Purpose
Ketamine intoxication has been mooted as a model of some of the signs and symptoms of psychosis. However, little research has focused on the self‐report experience of ketamine users. The purpose of the current study is to quantify (the frequency of occurrence of) ketamine induced phenomenology in recreational users. The paper also seeks to meaningfully group these experiences into facets and their principal components.
Design/methodology/approach
Respondents completed a checklist of experiences, the Ketamine Experiences Questionnaire (KEQ). Two samples were recruited via opportunity and snowball sampling one in 2009 (n=52) and one in 2010/11 (n=35).
Findings
The “Q‐sort” and principal component analysis (PCA) indicate that there are two factors, factor one representing aversive ketamine experiences (accounting for 48.2 per cent of the variance) and factor two representing appetitive ketamine experiences (accounting for 20.1 per cent of the variance). Ketamine induces a raft of appetitive, aversive and transcendental experiences many of which are illustrated. The data suggest that a decision about whether to continue using ketamine (and if so, how often) depends in part on an intuitive cost‐benefit analysis of the phenomenology that it induces.
Research limitations/implications
There are some notable limitations to the current study; the small sample size to variable ratio necessitated a “Q‐sort” before PCA; the sampling procedure prohibited the generation of a representative sample; and there were no means of independently verifying ketamine use.
Originality/value
This study represents a novel exploration into ketamine phenomenology and the principal components of these experiences.

Abstract
Purpose
This study examines the effectiveness of Zero-Contact Marketing that minimizes contact between employees and consumers in marketplaces by adopting an integrated research framework of motivation theory, servicescape model and the theory of reasoned action (TRA).
Design/methodology/approach
This study randomly collected 314 respondents through an online survey in May 2020 in South Korea. Structural equation modeling (SEM) assessed the overall hypothetical research model.
Findings
Zero-Contact Marketing facilitates the positive impacts of Korean consumers' motivations (intrinsic and extrinsic) and service environment on their word-of-mouth (WOM) intention to spread information about a store offering Zero-Contact Marketing service and the store revisit intention. In addition, consumers' attitude toward Zero-Contact Marketing and shopping pleasure (SPL) has stronger impacts on consumers' WOM intention than they do on the store revisit intention.
Research limitations/implications
The limitation of this study lies in that the survey participants responded only in South Korea, which may lead to biased results. To provide a more generalized insight, this study should be extended by considering consumers in other countries, since many consumers around the world tend to minimize face-to-face interaction and avoid unnecessary interruptions under the current pandemic.
Practical implications
By minimizing the social interaction between employees and consumers, Zero-Contact Marketing may increase consumers' shopping satisfaction with free shopping moments and no disturbance, especially under the COVID-19 pandemic.
Originality/value
The findings provide theoretical contributions by empirically validating the effects of intrinsic and extrinsic motivations and service environment on consumers' internal and external responses in a Zero-Contact retail setting.

The purpose of this study is to assess the quality of honey from different agro-climatic zones of Himachal Pradesh in terms of physicochemical characteristics and mineral status.
Abstract
Purpose
The purpose of this study is to assess the quality of honey from different agro-climatic zones of Himachal Pradesh in terms of physicochemical characteristics and mineral status.
Design/methodology/approach
Three honey-producing locations were selected within each agro-climatic zone, honey sampled from four separate apiaries within each location and analyzed for physicochemical characteristics and mineral status using standard methodologies. The data were analyzed using one-way analysis of variance with one-way classification, after appropriate transformation through online OP-STAT software and MS Excel. The correlation coefficient (r) was also calculated. Principal component analysis was done using XL-STAT software.
Findings
The honey of Zone 4 had highest fructose (36.62%), F:G ratio (1.55), acidity (46.07 meq/kg), vitamin C (25.04 mg/100 g) and diastase (19.22 DN), whereas the pollen density (76,666.67 pollen grains per 10 g), pH (5.94), sucrose (6.94%), hydroxy methyl furfuraldehyde (70.20 mg/kg), amino acid (103.83 mg/100 g), phenols (77.39 mg/100 g), Ca (81.04 mg/kg) and K (354.17 mg/kg) were highest for Zone 2. Highest electrical conductivity (0.24 mS/cm), moisture (16.50 %), glucose (34.20%) and P content (62.93 mg/kg) were recorded for Zone 1. Correlation studies indicated a significant positive correlation between pH and EC; EC and moisture; colour and pollen density. Examining the graphical distribution of the honey samples, a natural separation between honeys of four different agro-climatic zones was obtained.
Originality/value
The impact of geographical/agro-climatic variations in physicochemical characteristics of honey has not been worked out under the present scenario in Himachal Pradesh.

Abstract
Purpose
The purpose of this paper is to characterize monofloral and heterofloral honey samples (chestnut, lavandula, acacia and sunflower) from different regions of Turkey according to their physicochemical (moisture content, acidity, ash, sucrose, reducing sugar and hydroxymethylfurfural content) and biochemical properties to compare regional and species differences that are thought to contain different types of plant sources.
Design/methodology/approach
Physicochemical investigations were performed according to AOAC methods. Mineral analysis and volatile analysis were performed by using atomic absorption spectrometry and GC–MS, respectively. Antimicrobial activities of honey samples were evaluated based on disc diffusion method and minimum inhibition concentration (MIC) values. The assays followed to determine total phenolic content and antioxidative and activities are spectrophotometric methods.
Findings
The obtained values of physicochemical parameters are among the values that can be accepted according to legal regulations. The most abundant mineral was potassium, which made up 81 per cent of the total mineral content, ranging between 165.7 and 301.6 mg/kg. A total of 87 different volatile components, some of which are highlighted in the literature to have antimicrobial and antioxidant effects, were detected. The maximum phenolic content, antioxidant activity against DPPH radical and ferric reducing ability were detected in the chestnut honeys. All tested honeys showed antimicrobial activity with MIC values between 6.25 and 50 µg/mL.
Originality/value
The present study has the feature of being a large study in terms of the region from where honey samples were selected and choice of analysis. The values obtained from physicochemical parameters reveal that the honeys from related region can be consumed with confidence. The biological properties found in honeys make them products of high added value and excellent quality.

Abstract
The British countryman is a well‐known figure; his rugged, obstinate nature, unyielding and tough; his part in the development of the nation, its history, not confined to the valley meadows and pastures and uplands, but nobly played in battles and campaigns of long ago. His “better half”—a term as true of yeoman stock as of any other—is less well known. She is as important a part of country life as her spouse; in some fields, her contribution has been even greater. He may grow the food, but she is the provider of meals, dishes, specialties, the innovating genius to whom most if not all British food products, mostly with regional names and now well‐placed in the advertising armentarium of massive food manufacturers, are due. A few of them are centuries old. Nor does she lack the business acumen of her man; hens, ducks, geese, their eggs, cut flowers, the produce of the kitchen garden, she may do a brisk trade in these at the gate or back door. The recent astronomical price of potatoes brought her a handsome bonus. If the basic needs of the French national dietary are due to the genius of the chef de cuisine, much of the British diet is due to that of the countrywoman.
