Methods:The sample consisted of 568 students of a secondary school in Reynosa, northeastern Mexico,
of whom 280 were boys and 288 were girls (mean age 14.08±0.72 years, age range 13–16 years). In the
morning shift, 287 students attend classes on a schedule from 7:30 to 13:00 and the afternoon shift, 281
students, on a schedule from 13:20 to 19:00. Students completed a general information questionnaire,
the Sleep Timing Questionnaire and the Spanish version of the Morningness–Eveningness Questionnaire.
Results:The adolescents who attended the morning shift had earlier bedtime and waking time, but shorter
sleep duration than those who attended the afternoon shift. Those oriented to eveningness had later
bedtime, waking time, and a shorter sleep duration than those oriented to morningness. Two interac-tions were found between school shift and chronotype. First, with regard to waking time during weekdays,
students who attended the afternoon shift and were oriented to eveningness woke up later than those
who attended the morning shift and were oriented to eveningness; during weekdays, there were no dif-ferences between the waking time of morning-type and evening-type students who attended the morning
shift. Second, with regard to sleep duration on weekdays, students who attended the morning shift and
were oriented to eveningness had the shortest sleep duration. Furthermore, there were no differences
between sleep duration on weekdays in evening-type and morning-type students of the afternoon
shift.
Conclusion:Adolescents who attend classes in the morning shift and are oriented to eveningness are the
most sleep deprived. Those who attend the afternoon shift will have optimal sleep duration, regardless
of their circadian preference.

Seeking with this new ways of dealing with conflicts, the alternative methods of justice are able to create new practices in order to help and better support victims of crime. Nowadays, the alternative methods of justice (as, for example, the mediation programs and the family groups conferencing) have both legal and victimological backgrounds, based on research findings and theoretical studies.

has traditionally been understood as part of
a strategy to looking for family togetherness.
The phenomenon of children and young people
who travel alone across international borders
is becoming more frequent. The migration of
unaccompanied minors is but a manifestation of
the changes that migration processes are expe-rienced in recent years. Faced with this problem,
the study description makes a reflection on the
causes and factors that motivate migration of
unaccompanied minors, who were repatriated
across the border from Reynosa, Tamaulipas-McAllen, Texas (USA), during the study period
from January 2008 to December 2009. Just as

The demonologic concept is the most primitive form of understanding abnormal behavior. It is to the brain as a principal organ of the intellectual life. The psychopathological study has been making inroads since the beginnings of the structuring of the society to research in psychopathology, who came to bring a new panorama of studies.

value. At the national level it is a crime
that must be stopped, using all means
that the government has at its disposal.
This study focuses on the analysis of the
incidence of kidnapping in the state of
Tamaulipas in the period between 2005-2010. Information was obtained from the
preliminary investigations undertaken
in the Attorney General of the State of
Tamaulipas and the Unit for Kidnapping
Combat in the state. The kidnapping
has a greater presence in the towns of
Reynosa, Nuevo Laredo, Tampico and
Matamoros, the predominant type of
kidnapping in the state is the common
type, followed by organized crime, in
addition, males appear as the primary
victim and the most common age range
of 18 to 40 years. We conclude that in the
state of Tamaulipas border cities have
higher incidence of kidnapping in the
years between 2005-2010

in our country do not concern only to
those who administer justice, but also
to all those areas of action which have
an impact like in the academic side.
The concern for scientific research on
the impact of the new criminal consti-tutional reform, involves the study and
localization of professional training of
lawyers and criminologists. Therefore
this is important to attend a series of
criteria to establish an inner agency
network known as: constitutional reform and the administration of criminal
justice, organized by Academic Bodies
registered with the Faculty Improve-ment Programme (Promep), involving
the Universities of Tamaulipas, Nuevo
León, Tlaxcala and The Autonomous
University of Puebla. Also the time
teachers who are working full-time
free, and students of the Bachelor and
Masters. The purpose of this research
network focuses on the comprehen-sive study of the constitutional reform
in criminal matters. Addressing the
understanding of penal reform from
its more complex aspects to emphasize
strengths and weaknesses in the areas
of education

no stranger to this problem also causes
long term physical and mental effects
due to severe trauma injuries suffered by
victims of an experience like this. Every
person that is involved in a car crash ac-cident will have their lives change in numerous ways. Some, from an economic
standpoint; others will carry the physical injuries that will interfere with their
normal everyday existence and others,
will ultimately die and pass on to their
families the consequences of such a
terrible event.
The general objetive of this investiga-tion is to demostrate the constant death

become multifactorial and complex, modern society is structured
by a high pressure globalizacion, where people killed themselves.
This paper aims to present information on the prevalence and
trends of suicide as a cause of death for the people of Reynosa
Tamaulipas, Mexico, during the period 2000 to 2008, where there were 232 deaths by this event. We used data from the registration book
of violent deaths in the Department of Expert Services located in Reynosa. Where found the proportion of suicide showed eight men for every
woman and in general the method mostly used is hanging, used this by
both sexes, the most vulnerable population to commit suicide are the
young people in productive age, mostly people between 16-35 years for
males and females for the age of consumption is more likely less, it is
16-30 years. A higher prevalence of suicide was recorder on september
and on the day of the week is Monday, so it is necessary to implement
preventive measures with regard to the problem described.

Method: A total of 568 junior high school students were registered, 280 (49.30%) males and 288 (50.79%) females, mean age 14.08 ± 0.72 (13-16) years, 287 attended classes on the morning shift from 7:30 to 1:00h and 281 attended the afternoon shift from 13:20 to 19:00h. All participants answered a questionnaire on how they use before bedtime the computer and mobile phone. They were divided into two groups according to the use of each device, a group of higher use (GHU) (4-7 days per week; >105 min per day) and a group of lower use (GLU) (1-3 days per week; <105 min per day). In addition, participants answered a sleep timing questionnaire (STQ), the morgningness-eveningness questionnaire (MEQ) of Horne & Östberg and Epworth Sleepiness Scale (ESS).
Results: In the computer GHU, there was a delay on weekday bedtime (GHU: 24.13±1.65; GLU: 23.02±1.16, T=6.90, p<0.001), waking time (GHU: 8.25±1.16; GLU: 7.26±1.59, T=4.78, p<0.0001) and mid-sleep (GHU: 4.19±1.59; GLU: 3.14±1.13, T=6.73, p<0.0001); as well as on weekend bedtime (GHU: 25.48±2.16; GLU: 24.21±1.69, T=4.78, p<0.0001), waking time (GHU: 11.11±1.90; GLU: 10.22±1.67, T=4.51, p<0.0001) and mid-sleep (GHU: 6.30±1.64; GLU: 5.21±1.34, T=6.48, p<0.0001). Increased daytime sleepiness was observed (HFG: 7.59±3.97; GLU: 6.53±4.22, T=2.40, p<0.01) but no differences were observed between groups on sleep duration. In the mobile phone GHU, there was a delay on weekday bedtime (HFG: 24.09±1.69; GLU: 23.23±1.33, T=5.51, p<0.0001) and waking time (HFG: 8.18±2.07; GLU: 7.62±1.75, T=2.87, p<0.01) as well as on weekend bedtime (HFG: 25.49±2.11; LFG: 24.55±1.91, T=4.41, p<0.0001), and waking time (HFG: 10.95±1.90; GLU: 10.57±1.79, T=2.03, p<0.05), sleep duration on weekend was decreased (HFG: 9.49±2.33; LFG: 10.02±1.94, T=-2.42, p<0.01). No differences were found between groups on sleepiness. The aforementioned effects were observed in participants from both shifts (morning and afternoon), however the effects were higher on the afternoon shift.
Conclusion: These results suggest that the use of computer and mobile phone before bedtime delay the sleep phase, especially on participants from the afternoon shift.

Method: A total of 568 junior high school students were registered, 280 (49.30%) males and 288 (50.79%) females, mean age 14.08 ± 0.72 (13-16) years, 287 attended classes on the morning shift from 7:30 to 1:00h and 281 attended the afternoon shift from 13:20 to 19:00h. All participants answered a questionnaire on how they use before bedtime the computer and mobile phone. They were divided into two groups according to the use of each device, a group of higher use (GHU) (4-7 days per week; >105 min per day) and a group of lower use (GLU) (1-3 days per week; <105 min per day). In addition, participants answered a sleep timing questionnaire (STQ), the morgningness-eveningness questionnaire (MEQ) of Horne & Östberg and Epworth Sleepiness Scale (ESS).
Results: In the computer GHU, there was a delay on weekday bedtime (GHU: 24.13±1.65; GLU: 23.02±1.16, T=6.90, p<0.001), waking time (GHU: 8.25±1.16; GLU: 7.26±1.59, T=4.78, p<0.0001) and mid-sleep (GHU: 4.19±1.59; GLU: 3.14±1.13, T=6.73, p<0.0001); as well as on weekend bedtime (GHU: 25.48±2.16; GLU: 24.21±1.69, T=4.78, p<0.0001), waking time (GHU: 11.11±1.90; GLU: 10.22±1.67, T=4.51, p<0.0001) and mid-sleep (GHU: 6.30±1.64; GLU: 5.21±1.34, T=6.48, p<0.0001). Increased daytime sleepiness was observed (HFG: 7.59±3.97; GLU: 6.53±4.22, T=2.40, p<0.01) but no differences were observed between groups on sleep duration. In the mobile phone GHU, there was a delay on weekday bedtime (HFG: 24.09±1.69; GLU: 23.23±1.33, T=5.51, p<0.0001) and waking time (HFG: 8.18±2.07; GLU: 7.62±1.75, T=2.87, p<0.01) as well as on weekend bedtime (HFG: 25.49±2.11; LFG: 24.55±1.91, T=4.41, p<0.0001), and waking time (HFG: 10.95±1.90; GLU: 10.57±1.79, T=2.03, p<0.05), sleep duration on weekend was decreased (HFG: 9.49±2.33; LFG: 10.02±1.94, T=-2.42, p<0.01). No differences were found between groups on sleepiness. The aforementioned effects were observed in participants from both shifts (morning and afternoon), however the effects were higher on the afternoon shift.
Conclusion: These results suggest that the use of computer and mobile phone before bedtime delay the sleep phase, especially on participants from the afternoon shift.
