Heat also facilitates the transmission of water through the cell walls, thereby assisting its passage from the interior to the surface of the material; it increases the vapour pressure of water, thus increasing its tendency to evaporate; and it increases the water‐vapour‐carrying capacity of the air. In the United States the unit of heat customarily used is the British thermal unit (B.t.u.), which for practical purposes is defined as the heat required to raise the temperature of a pound of water 1° F. Heat is commonly produced through the combustion of oil, coal, wood, or gas. Heating by electricity is seldom practicable because of its greater cost; but where cheap rates prevail it is one of the safest and most efficient, convenient and easily regulated methods. Direct heat, direct radiation and indirect radiation are the types of heat generally employed. Direct‐heating systems have the highest fuel or thermal efficiency. The mixture of fuel gases and air in the combustion chamber passes directly into the air used for drying. This method requires the use of special burners and a fuel, such as distillate or gas, which burns rapidly and completely, without producing soot or noxious fumes. The heater consists simply of a bare, open firebox, equipped with one or more burners, an emergency flue to discharge the smoke incidental to lighting, and a main flue, through which the gases of combustion are discharged into the air duct leading to the drying chamber. Direct‐radiation systems also are relatively simple and inexpensive and have a fairly high thermal efficiency. A typical installation consists of a brick combustion chamber with multiple flues, which carry the hot gases of combustion back and forth across the air‐heating chamber and out to a stack. The air is circulated over these flues and heated by radiation from them. The flues are made of light cast iron or sheet iron. The air‐heating chamber should be constructed of fireproof materials. The efficiency of the installation depends upon proper provision for radiation. This is attained by using flues of such length and diameter that the stack temperatures will be as low as is consistent with adequate draught. Heating the air by boiler and steam coils or radiators is an indirect‐radiation system, as the heat is transferred from the fuel to the air through the intermediate agency of steam. Such a system costs more to install and has a lower thermal efficiency than either of the other two systems. It is principally adapted to large plants operating over a comparatively long season on a variety of materials where the steam is needed to run auxiliary machinery or to process vegetables. Large volumes of air are required to carry to the products the heat needed for evaporation and to carry away the evaporated moisture. Insufficient air circulation is one of the main causes of failure in many dehydrators, and a lack of uniformity in the air flow results in uneven and inefficient drying. The fan may be installed to draw the air from the heaters and blow it through the drying chamber, or it may be placed in the return air duct to exhaust the air from the chamber. An advantage of the first installation is that the air from the heaters is thoroughly mixed before it enters the drying chamber. It has been claimed that exhausting the air from the chamber increases the rate of drying by reducing the pressure, but the difference is imperceptible in practice. Either location for the fan is satisfactory, and the chief consideration in any installation should be convenience. Close contact between the air and the heaters and between the air and the material is necessary for efficient transfer of heat to the air and from the air to the material, and to carry away the moisture. The increased pressure or resistance against which the fan must operate because of such contact is unavoidable and must be provided for, but at other points in the system every effort should be made to reduce friction. To this end air passages should be large, free from constrictions, and as short and straight as possible. Turns in direction should be on curves of such diameter as will allow the air to be diverted with the least friction. The general rule in handling air is that a curved duct should have an inside radius equal to three times its diameter. The water vapour present in air at ordinary pressures is most conveniently expressed in terms of percentage of relative humidity. Relative humidity is the ratio of the weight of water vapour actually present in a space to the weight the same space at the same temperature would hold if it were saturated. Since the weight of water vapour present at saturation for all temperatures here used is known, the actual weight present under different degrees of partial saturation is readily calculated from the relative humidity. Relative humidity is determined by means of two thermometers, one having its bulb dry and the other having its bulb closely covered by a silk or muslin gauze kept moist by distilled water. Tap water should not be used because the mineral deposits from it clog the wick, retard evaporation, and produce inaccurate readings. The wick must be kept clean and free from dirt and impurities. The two thermometers are either whirled rapidly in a sling or used as a hygrometer mounted on a panel with the wick dipping in a tube of water and the bulbs exposed to a rapid and direct current of air. The relative humidities corresponding to different wet‐ and dry‐bulb temperatures are ascertained from charts furnished by the instrument makers, or published in engineers' handbooks. As a general rule, the more rapidly the products have been dried the better their quality, provided that the drying temperatures used have not injured them. Some fruits and vegetables are more susceptible to heat injury than others, but all are injured by even short exposures to high temperatures. The duration of the exposure at any temperature is important, since injury can be caused by prolonged exposure at comparatively moderate temperatures. The rate of evaporation from a free water surface increases with the temperature and decreases with the increase of relative humidity of the air.

Effective safety communication facilitates the sharing of relevant knowledge that helps to improve safety behaviours, such as superior hazard identification and compliance. This study aims to explore channels by which construction companies can effectively communicate health and safety (H&S) among communities of their operations.

Based on a quantitative research approach, this study addressed the knowledge gap through a cross-sectional survey of 250 contractors (comprising 155 building and 95 road contractors) involved in various projects in the Ghanaian construction industry. These contractors were selected by using a stratified simple random sampling technique. Data obtained from the survey was analysed through descriptive (i.e. frequencies, mean and standard deviation) and inferential (i.e. exploratory factor analysis) statistical analyses.

The findings from the mean scores revealed that all the 12 communication channels identified in the literature, confirmed through piloting and examined by the respondents, were important channels through which construction companies can effectively communicate H&S amongst communities of their operations. The exploratory factor analysis revealed a clustering of the 12 channels of communication into 5 components: “safety demonstration in the community”; “social media”; “mass media”; “community engagement”; and “opinion leaders”.

This study offers construction project managers the means of managing one of the major stakeholders of a construction project (the community). It provides an actionable opportunity that can be leveraged strategically to integrate community members into projects to promote synergy and local content inclusion while gaining a peaceful atmosphere to achieve their project goals.

Practically, this study provides construction project managers with a means of managing one of the major stakeholders of a construction project (the community) and also demonstrates the integration of community members into projects to promote synergy and local content inclusion. This would give construction organisations a peaceful atmosphere to accomplish their project objectives.

The social implication of this study is that the study offers society a means of creating safer Ghanaian communities by offering them the knowledge of identifying hazards and avoiding risky behaviours, creating a good safety atmosphere in these communities.

This study presents construction organisations with a unique opportunity to transfer and share novel external knowledge within a different social system (the community). It contributes to the state-of-the-art knowledge in H&S communication by providing channels through which H&S can be communicated in a developing country such as Ghana.

The auditing profession has been an important feature of industrialized economies for many years. The manner in which the auditing profession is regulated in the insurance industry, therefore, is worthy of investigation in light of the recent collapse of Heath International Holdings (HIH) which is currently recorded as the biggest corporate collapse in Australia's history. Two questions remain: did the HIH auditors carry out the work ethically and responsibly? Did the regulators fulfill their responsible roles? Among all factors that have led to the collapse of HIH, that of the auditor's role and the auditing profession's ethics has assumed particular importance.

The police require the cooperation of the public to ensure security in society. People cooperate with the police because they share norms and values reflected in the law and police action. Police face challenges in obtaining the cooperation of the public. There are studies examining the relationship between the legitimacy of the police and cooperation with the police. Using Tankebe's (2013) model of legitimacy as a multidimensional concept, this study examines the relationship between legitimacy and cooperation with the police in India.

For examining the relationship, the study uses data collected from a survey of 705 victims of crime in India who had interacted with the police. The research questions were examined using structural equation modeling (SEM).

On the basis of the analyses, the study concludes that legitimacy is a multidimensional concept encompassing police lawfulness, procedural justice, distributive justice and effectiveness. The legitimacy of the police has both a direct impact on cooperation with the police and the obligation to obey as a mediating variable. The study indicates that legitimacy is an important antecedent to cooperation with the police, which has significant policy implications.

The study is significant as there are no studies examining the relationship between the legitimacy of police and cooperation with the police in India, which is a non-Western developing country and the largest democracy in the world. The present research is the first study of this nature.

The degree to which accidents happen or are prevented in any organisation is the function of both the health and safety culture and the safety culture maturity level of the organisation. Therefore, this paper aims to determine the state of health and safety culture in the construction industry in developing economies and to assess their category on the safety maturity ladder using the Ghanaian construction industry as an example. This is to help construction companies in developing countries become conscious of the state of health and safety in the industry so they can be motivated to improve along the ladder.

In total, 250 contractors made up of 155 building contractor,s and 95 road contractors took part in the survey. The sample size was determined by Yamane’s (1967) formula with stratified simple random sampling technique adopted in selecting the companies in the survey. This paper also uses (Guttman Scale) Scalogram analysis to measure the state of health and safety culture in the Ghanaian construction industry.

The results show that health and safety culture of the Ghanaian construction industry is at the first level, the pathological stage. Even though Ghanaian contractors have health and safety policies and codes of conduct in place, safety is not seen as a key business risk. Consequently, management and most frontline staff do not emphasise the importance of integration of safety measures in the various activities on the site. Thus, safety is not seen as unavoidable and a part of the construction activity.

The findings of this study inform state authorities, consultants and contractors of areas that they need to focus more on improving health and safety culture in developing countries. This would go a long way in protecting construction workers in the industry.

This study, to the best of the authors’ current knowledge, is the first of its kind in the Ghanaian construction industry. The study brings to the fore the actual state of health and safety in the construction industry in developing countries such as Ghana. The value of the findings lies in the fact that it will provide the motivation for construction companies in developing countries to develop a commitment to safety, and to provide appropriate and effective safety improvement techniques to progress to the subsequent stages of the safety culture maturity ladder.

This paper aims to contribute towards our knowledge and understanding of volunteer street patrols working within community safety and pluralised policing. Through the increased responsibilisation of communities and individuals, volunteers are taking to the streets to help others in need and support the community safety infrastructure. The example of volunteer street patrols is used to explore the motivations of individuals participating in the local delivery of community safety and policing.

This research is drawn from ethnographic research consisting of 170 hours of participant observation on the streets of a northern UK city, Manchester, supported by 24 semi-structured interviews with volunteers and stakeholders who participate in a street patrol and those working alongside them.

Using a three-paradigm perspective for volunteer motivations, the themes altruism, civil connection and volunteering for leisure are applied to explore volunteer motivations. Through their actions, volunteers in the street patrol are motivated volunteers who can offer an additional and important resource within the local community safety and pluralised policing infrastructure.

This paper highlights volunteer street patrols offer a caring and supportive function to people in need on the street, one in support of the police and other agencies. It contributes to the growing understanding of those who volunteer in policing and community safety landscapes. As responsibilised citizens, they have an increased awareness of social problems. They are motivated individuals who wish to create and maintain safety and play an important role in policing the night-time economy.

Justice rules are standards that serve as criteria for formulating fairness judgments. Though justice rules play a role in the organizational justice literature, they have seldom been the subject of analysis in their own right. To address this limitation, we first consider three meta-theoretical dualities that are highlighted by justice rules – the distinction between justice versus fairness, indirect versus direct measurement, and normative versus descriptive paradigms. Second, we review existing justice rules and organize them into four types of justice: distributive (e.g., equity, equality), procedural (e.g., voice, consistent treatment), interpersonal (e.g., politeness, respectfulness), and informational (e.g., candor, timeliness). We also emphasize emergent rules that have not received sufficient research attention. Third, we consider various computation models purporting to explain how justice rules are assessed and aggregated to form fairness judgments. Fourth and last, we conclude by reviewing research that enriches our understanding of justice rules by showing how they are cognitively processed. We observe that there are a number of influences on fairness judgments, and situations exist in which individuals do not systematically consider justice rules.

The case was created via an interview of the protagonist in 2018 at the US Military Academy by the authors.

The case describes the dilemma First Lieutenant Williams faces when his platoon sergeant unexpectedly leaves. Organizational norms and accepted practices suggest Lieutenant Williams should choose the most senior squad leader, Staff Sergeant Boyer. The departing Platoon Sergeant even recommended Staff Sergeant Boyer. However, based on recent observations, Lieutenant Williams felt Staff Sergeant Boyer may not be the best fit. Instead, the lieutenant considered choosing the newest squad leader, Staff Sergeant Harrison, who seemed to be highly proficient, but had yet to prove himself. Before the lieutenant could fully weight his options, Staff Sergeant Boyer confronted him about a decision.

This case is designed for use in undergraduate courses on leadership and management. The case was not only designed primarily for teaching a lesson on organizational justice, but can also be used to integrate lessons on communication, power and influence, and decision making. Each of these elements is present in the case. The instructor can choose to incorporate them into the lesson for a more wholly encompassing lesson or choose to focus on only the organizational justice aspects at play in the case.

Injustice is perceived, experienced and articulated. Social movements, and their constitutive parts, frame and re-frame these senses of injustice. Two often-overlapping accounts of social movements are in focus in this chapter. Human geography has been flooded with movement-based analyses of environmental justice (EJ). Sociology (more appropriately political sociology) has provided insight into social movements in the form of ‘contentious politics’ (CP). Building on both sets of literature, this chapter seeks to advance thought in human geography through a detailed exploration of master and collective action framing. It argues, firstly, that framing analysis challenges activist researchers to retain ‘spatial constructs’ as their central focus, rather than discourse. It calls, secondly, for us to unbind injustice as much as justice in our analysis of framing. And lastly, it demands a multi-spatial perspective on framing beyond simply scalar accounts.
