Five Important Aspects of an Emergency Light

When you are purchasing an emergency light, you could go on comparing the available models for ever, without ever coming to a conclusion. There are plenty of options that could confound anyone when it comes to picking the best solution for emergency lighting. However, there are some important aspects which cannot be overlooked, on the basis of which you can pick lights that you can use in emergencies. These aspects of lighting also indicate the quality of the equipment you are using, which is another reason why you should measure their effectiveness based on this benchmark.

The emergency light shouldn’t consume large amounts of energy. Low energy consumption translates to lower energy costs, and cost efficiency is an important theme these days with scarcity of energy. It is also true that lower energy consumption makes the light source environmental friendly which is another positive aspect.

However, the reason you are looking for low energy consumption in case of emergency lighting is not to save money or to save energy for the betterment of the environment but to be able to use the light source for a longer period of time. Energy and cost savings are an added bonus, once you can be assured that your light source will last you a stipulated number of hours during a rescue operation as opposed to carrying backup for every mission.

The power supply that is required for emergency light should be lower and portable. This is once again derived from the fact that emergency lighting should consume less energy. A good example is provided by LED lights. LED flashlights, beacons or even LED light bars usually comprise of 1W – 10W LEDs which are powered by a simple 12 – 24V DC supply. The rechargeable battery on which huge demands are not placed by LEDs would be able to power the lights for a longer period of time, once it is recharged. Since you can never be sure about the time duration of an emergency mission you would need power supplies that will last longer. At the same time, when you are hurriedly stuffing important supplies in order to head out on an emergency mission, you cannot be overburdened with multiple batteries or power supply sources. This is why your emergency lighting should consume as less energy as possible.

The emergency light should be reliable in the true sense of the word. LED lights are used for scenarios where reliability is extremely important, whether it is rescue missions, marine operations or highway lighting during constructions or wreckage clearance. The LED lights are very resilient thanks to their polycarbonate bases and thermoplastic, high impact and vibration resistant casings. Extruded aluminum helps in efficient heat dissipation too. The durable LED light bars are good for rugged usage, which is expected during emergencies. They can be used in all kinds of weather thus providing good support at all times, as one can never be sure about the kind of weather that will be encountered during an emergency. Lastly, emergency lighting should offer good control, whether it is of the intensity, flashing or of the beam angle.

Tutoring Mathematics

Learning the fundamentals of mathematics is intrinsically
important to being able to understand 
higher concepts. Mathematics at its very nature is a subject that builds
upon previously learned knowledge. All too often students slip between the
cracks, or are left behind in the classroom setting, as the teacher moves from
one concept to the next when the majority of the students seem able to perform
the requisite skills.

Whether the student is only able to parrot back the answers
without understanding the concepts behind them, or they understand the concepts
but get confused in the actual computing, once they begin to fall behind, it
becomes ever more challenging to catch up. It is vitally important to ensure
that students are comfortable in the theory as well as the practical aspects of
mathematics, and for students who are struggling, tutoring can be the best
solution.

Working one on one, the tutor can discover where the
learning gaps are with relative ease.

It then becomes a matter of returning not
only to the stage where the student is floundering, but more importantly to the
stage immediately preceding that. 

Many people struggle with math, believe that math is hard,
and they will never be good at it. This is in large part because of those gaps
in knowledge and understanding, and if they are not reassured and taken back to
place of competence, then any tutoring will simply be a Band-Aid solution. It
is far better to work for a session or two at a level of competence, to build
up the students confidence and then to move ahead to the next level.

At this point, it is important to assess that there is solid

understanding of the concepts as well as the ability to do the computations.
Once the student has gained mastery of each stage, their confidence will
increase and they will be able to build upon their successes.

Of course, there are students to whom math is a serious
challenge, and it is up to the tutor to find ways to get the concepts across,
be it through math games, the use of manipulatives or with real life examples.
Not all students learn in the same manner, and it behoves the tutor to discover
in what manner their student learns best.

Debate on the aim of criminology in speaking truth to power

Article by Michelle Robert

Introduction

In order to understand whether criminology can speak truth to power, it is essential to first understand the concept of truth and knowledge and these will be elaborated in detail through Foucault’s ideas.Analysis of truth and power.In this regard, it can be asserted that moral order and ethics are different because the latter is concerned with objectivity within moral order. According to this order, truth should not just be regarded as a characteristic that is only confined to a certain aspect of freedom; these two are disconnected. Instead, Foucault proposes that truth can be confirmed by certain levels of truth. Power is something that can be manifested only when examined in the form of a relationship.Power can be understood in terms of a number of theories. For instance, according to feminists, women need to be given equal opportunities in the social, political and economic spheres in their lives. This equality in opportunities can only be possible when both sexes are granted power over their lives.In the Game theory, power is imagined to be something that individuals can either use to their advantage or their disadvantage depending on how they opt to influence others. Additionally in the rational choice theory, power is thought of as something that needs to be acquired by certain social actors so that they can achieve their goals and aspirations. (Redhead, 1993, pp 13) Through this author’s assertions, it is possible for one to understand some of the underlying issues that cause manifestation of power. According to him, knowledge and truth were necessary in placing power within context. Given these assertions, then power can be seen through any of the following entities-The government-Television status-Family-Big business-The police -Judiciary-Seat of power -EtcSince these are all concepts that require in depth examination, the essay shall be limited only to the government as a manifestation of power.

Understanding criminology

Criminology may be defined as the sociological approach towards the study of crime. In this field, crime can be treated on an individual basis also in terms of a sociological phenomenon. Criminology is one of the most diverse fields to be studied because it encompasses so many disciplines. Examples of such disciples are; law, behavioural sciences, psychology, sociology etc. Usually research in this field entails causes, consequences, forms, incidences of crimes and many others. (Wilson, 2001, pp 39)Criminology has a series of theories and schools of thought that are established in understanding crime.

Cultural criminology

Cultural criminology may be defined as the study of the causative aspects of crime through the cultural lens. In this approach, culture may be viewed as a n aspect that propagates crime. On the other hand, crime may be regarded as a crime or a form of crime in its own right. (Hayden, 2004, pp 45)There are certain styles or levels of entities that are distinct to particular cultures. Adherents to this school of thought claim that legal authorities normally create their own symbols that are made in reaction to the criminal subcultures. More often than not, it is possible to identify these reactions within society and examples here include;* Campaigns for support from the public* Changing legal structures * Changing political systems* Moral entrepreneurs* Mass symbolism * Educational efforts

Cultural criminology speaking truth to power

In certain instances, some elements of culture can be perceived as crime themselves as described by cultural criminologists. Through the latter group’s assertions, it is possible to see how power can be challenged by their deductions. For instance criminology can identify examples in which the government has labelled certain expressions of culture as crime and thus gone a long way in promoting the behaviour. Through criminology, it is possible to highlight these situations and thus challenge the government which is a form of power. (Valier, 2003, p 120)Taking the example of what had occurred in Britain during the 1970s; at that time there was a band known as the Sex Pistols that had been highly controversial. The reason behind this controversy was because of the style and image portrayed by this Punk Band. The group had been organized by the Virgin Records Company and was labelled by the government (through its representatives) of the following criminal acts;* Anarchy* Bondage* Fascism * EtcAccording to local politicians, this group was a threat to the moral order of British society and as such should be dealt with severely. Most of the problems being faced by this group were actually brought on by the government because of what they perceived as ‘crimes’. In fact, the government banned any of their materials from being sold or promoted in stores.For instance an art photographer known as Jock Sturges had been interrogated and arrested by the police under claims that he had been engaging in criminal activity. According to the authorities, the process of taking nude photographs (which had been the case with this group) had constituted a criminal offense and thus necessitated arrest. (Tierney, 2006, pp 26)

* Gay visual artists* Black raps artists* Punk bands* Musical production* Latino suitersCriminologists have thus shown that the government has a part to play in criminalization and that they should take up responsibility for it.

Conclusion

Criminology can speak out against power because of the insights that the concept manages to bring with regard to the government’s role in criminalizing behaviour. By singling out these matters, cultural criminology has illustrated just how assertive it can be. The latter phenomenon has been particularly useful in protecting the rights of targeted groups because some of these attacks spearheaded by the government have now been eliminated.
