The research study aims to determine the ecological conditions of dusung and non dusung, and the role of the contribution to environmental conservation in Ureng Village. The research method used was purposive sampling with observation parameters were microclimate (CO2 content, air temperature, humidity), vegetation conditions and soil conditions (soil temperature, soil moisture, soil pH, soil moisture content, soil macrofauna and organic C) . The results of  Paired of each parameter measured mostly show a smaller calculated t value compared to the t0.05 table value (1.8595) which means that the parameter is not a real difference, ie for the air humidity, t count = 0.27,; soil pH, t count = 0.6; soil macrofauna, t count = -0.66 and vegetation, t count = 1.01. As for the parameters of CO2; air temperature, soil temperature, , soil water content and organic C, t value of CO2 gives the value t count = - 16.06; air temperature = -5.11; soil temperature = -3.62; soil moisture, t count = 2,16; soil water content = 8.47, and C-Organic = 8.53; t count value which is greater than t table value which shows that there is a significant difference between CO2, air temperature, soil temperature, soil moisture, soil water content and C-Organic content in the dusung area which is greater than in the non-dusung area. From the results of the analysis it is known that dusung has a better role in environmental conservation when compared to non dusung which is indicated by the value of CO2 air temperature, soil temperature, soil moisture, soil water content and C-organic content.

Authors: Rizal Faisal , Hanif Hanif
Published: June 2019

Life time (umur layan) struktur beton yang berada dilingkungan yang korosif sampai saat ini masih menjadi permasalahan yang besar. Salah satu permasalahan tersebut adalah terjadi penurunan kuat tekan beton pada umur 56 hari sebesar 8,17% akibat adanya agresi asam sulfat, penurunan ini terjadi seiring dengan adanya perubahan pada mikrostruktur beton. Hal ini dikarenakan terbentuknya senyawa gypsum (Ca SO4 .2H2O) dan ettringite (Ca6Al2SO43OH2 . 25H2O) sehingga terjadi microcrack dan beton menjadi lebih porous. Hasil pengujian X-Ray Difractometer, Scanning Electron Microscope dan Mercury Injection Capillary Pressure pada penelitian ini memperlihatkan adanya perubahan-perubahan yang terjadi pada mikrostruktur beton akibat agresi asam sulfat.
Thermodynamic and Kinetic Desorption Analysis on Direct Air Capture of CO2 Gas Using Moisture Swing Sorbent
Authors: Talapatra Akash
Published: June 2019

An anion exchangeable resin sorbent originated from amine was
used to capture & absorb CO2 from atmospheric air. The sorbent
is capable to absorb CO2 gas in dry location, though it releases CO2
gas when it is exposed to water vapor or liquid water. The isotherm test on absorption provides
the evidence that the sorbent can act effectively at the very low concentration
of CO2. Its capacity of absorption in the form of carbonate ion is
0.86 mol/kg, which is identical to nearing of 21 liter of CO2 gas
under 100 kPa & 25⁰C. Langmuir equation detailed the
absorption isotherm better at higher saturation. The kinetic desorption of CO2
spread over in a flat polypropylene sheet has been practiced by the well
developed models & experiments. After that, the desorption coefficient,
kinetic desorption parameters & stimulated energy are estimated with that
equation & model. Finally more experiments should be developed to find out
the exact reaction mechanism on this method with accumulating new information.

Published: June 2019

The present study was carried out in Mahi Canal Command area in Vadodara district for monitoring the environmental impact of water logging and salinity on agriculture using Multi-temporal Remote Sensing data of past 15-years. The Indian Remote Sensing Satellite (Resourcesat-1) LISS-III, LISS-IV and Landsat TM data of 2000, 2006, 2010 and 2016 covering study area was analyzed for mapping waterlogged and salt-affected areas. The data from open-well observations was also collected to monitor the impact of canal irrigation on water-table and in turn on water-logging in the study area. The point measurements of open-well data were used to generate spatial distribution maps using Inverse Distance Weighting (IDW) Interpolation technique and these were superimposed on Satellite data. The waterlogged and salt-affected areas delineated using Remote sensing data was validated by carrying out detailed field survey as well as spatial IDW layers of water-table in the study area. The results of analysis of agricultural area indicate that agricultural area has substantially increased due to introduction of canal irrigation which has helped to improve socio-economic condition of the farmers in the Vaghodia taluka. Agricultural area of medium and dense categories has increased during 2000 to 2016 accounting an increase from 12% to 26% in case of medium and 6.9% to 20% in dense agriculture, respectively. The water table in some of the villages in the study area has slightly come up during the period of last 15-years and at most predominantly after introduction of canal irrigation but it is much below to cause any water logging problem. However, it was also observed that waterlogged and salt-affected areas have decreased over the period of one decade due to augmentation of drainage system in the study area.

Authors: Kalubarme MANIK , Acharya Mithwa , Shukla Shital H.
Published: June 2019

Remote sensing (RS) and Geographic Information System (GIS) has played a
major role in the study of different types of drought i.e. agricultural or hydrological
drought. The present study on agricultural Drought assessment was carried out
in the Patan District of North Gujarat, India. This study focuses on the
assessment of climate change and its impact on Agriculture using Remote Sensing
(RS) and GIS technology. The Landsat-7 TM and Landsat-8 OLI data of
February-2002 and February-2018 covering Patan District was analysed for Land
use/Land Cover mapping and monitoring changes in agricultural area over the
period of 16-years. The Spectral vegetation index namely Normalized Difference
Vegetation Index (NDVI) was computed using Landsat-7 TM and Landsat-8 OLI
digital data for assessment of changes in agricultural vegetation during the
drought and normal monsoon periods. Meteorological data like Minimum &
maximum Temperatures and rainfall was collected from State Data Centre. Various
Drought indices like Standardized Precipitation Index (SPI), Potential
Evapo-Transpiration (PET) and Aridity Index (AI) were computed using meteorological
data of past 16-years.

 

The results indicate that total agricultural
vegetation during drought season was only 21.9 per cent (2002) which has
increased to 58.7 per cent during the normal monsoon season of 2018. The
rainfall deviations were computed for various years and it was observed that high
negative rainfall deviations (-40 to -70%) having low rainfall occurrence were
associated with negative SPI values ranging from -0.5 to -1.1 in Patan
district. These positive rainfall deviations were associated with positive SPI
values of 1.08, 0.57 and 0.62 of respective years indicating moderately wet and
mildly wet conditions. During drought year of 2002 total precipitation was very
less resulting in Aridity Index of 0.09 which is classified as hyper arid for
the Patan District.

Published: June 2019

Terkos Lake Formed by the
invasion of sea water, the ancient average area calculated as geomorphological
is 25 km2. Although the area covered by the lake changes in certain ratios, it
has been subject to dramatic changes over time depending on the region. It can
be defined as being the most important water basin of Istanbul, and it is an
area where scientific work has not been carried out despite all its natural and
special beauties. Whereas, being one of the basins of Istanbul, it has been
observed that the works carried out at the technical level were carried out by
DSİ and İSKİ. The surface area of the lake is 41 km2 and a total drainage area
of 775 km2, is approximately 12 km in length and 5 km in width. It is obvious
that the morphological features of the lake area, which is located at the
border of the most complex and impressive morphological structures. For this
purpose, morphometric studies are carried out on the streams feeding the lake
and the findings of some shells in the lake and Black Sea are shared in this
study.
EU rescue and restructuring state aid guidelines
Authors: Obradović Mazal Tamara
Published: June 2019

Undertakings in difficulty, having
exhausted all market options, may resort to State aid to rescue and/or
restructure its operations in order to return to viability. the author looks
closer into the opportunity for such undertakings to change within so as to
abandon practices which may have represented at least one of the roots of the
deficiencies leading them to difficulties. The stringent rules of rescue and
restructuring of firms in difficulties provide a second chance to restore their
business, account of debts, take stock of actions and potentially rise again.
Yet, the overall restructuring given as a second chance by the State aid and
the role of the state, should not present a carte blanche for old policies

and approaches to be repeated with the taxpayers’ money. The restructuring
should also be a stock-taking opportunity, an internal scrutiny where the
corporate culture and the governance of the undertaking changes as well. There
should be room to (re)consider corporate governance and audit of corporate
culture as elements of restructuring process as well as restructuring plans, to
prevent the undertaking on the receiving end of State aid to lapse again. Being
given a second chance, applying practices and exercising behaviour

that (may) have lead the undertaking to its difficulties, is not a guarantee of
successful restructuring and return to viability but may, indeed, represent an
internal subjective peril to the objective restructuring goals to be achieved.
Hence, the author explores whether non-tangible elements such as an enhanced
corporate governance and change of corporate culture, should be introduced as
mandatory in the course of undertaking restructuring. The author does not probe
into corporate governance and corporate culture as such, but perceives

them as welcoming factors to achieve the desired outcome of restructuring aid,
namely a successful return to viability using restructuring aid.
Social protection of workers in non-standard forms of employment in Slovenia
Authors: Senčur Peček Darja
Published: June 2019

The article deals with legal position of individuals who work in various nonstandard forms of employment in Slovenia. The author analyses labour law protection and social position of workers, carrying out the work in forms of temporary work (fixed-term employment, temporary and occasional work of students and retired people), in employment relationships with more than two parties (temporary agency work), and also the position of false self-employed and economically dependent persons. It is evident that these forms of work are not precarious on their own, since Slovenian legislation provides the workers with rather proper protection during the period, in which they work, and moreover, these workers are also entitled to rights from social insurance schemes (in narrower of broader scope). The situation is different in cases of abuse of these forms of work and in cases of false self-employed persons and other disguised employees, when workers are only entitled to a limited scope of rights in spite of working in relationships with elements of a standard employment relationship. In order to prevent these cases, not only additional legislation solutions and labour market measures are needed, but labour inspection will also have to be increased and furthermore, the awareness of employers and the society regarding long-term impacts of use of such non-standard forms of work will have to be raised.

Published: June 2019

This
qualitative case study studied and explored how seven senior high school teachers in the Philippines taught Media and Information Literacy in the early years of its implementation through interviews, and analysis of
the teachers’ lesson plans. To guide the data analysis, the researcher used the
seven phases of analytic procedures or data analysis as described by Marshall
and Rossman (2011). Results revealed that there was confusion and
misunderstanding among school authorities as to the qualities of prospective
MIL teachers as shared by the informants; motivation and preparation of MIL
teachers were inadequate; and teachers did not have a deep understanding of the
meaning, significance, and scope of the subject, MIL. Furthermore, the selected
teachers simply used whatever strategies they know; and materials were not
readily available for their use.

In the course of one year the working group for quality criteria of the Citizen Science Network Austria developed a catalogue of criteria for citizen science projectson the platform Österreich forscht. From this catalogue questions were generated, which should help the project leaders of projects in Austria to fulfil the criteria. By answering the questions, important topics are addressed during the implementation of a project and can thus also be considered by the project management. On the other hand, the answers help potential project participants to make an informed decision about participation on the basis of the information presented.Project leaders receive this catalogue of questions and send the answers back to Österreich forscht. The platform coordinators read the answers, consult with the Working Group for Quality Criteria if necessary and contact the project leaders in case of ambiguities for clarification and possible assistance. The aim of this processis not to exclude individual projects, but to jointly ensure the quality of the citizen science characteristics of the projects and eventually even increase them. An open dialogue and exchange and a respectful interaction between all participants is the prerequisite for this.

A Visualization Tool for Analyzing the Suitability of Software Libraries via Their Code Repositories
Authors: Haber Casey , Gove Robert
Published: June 2019

Code repositories are a common way to archive software source code files. Understanding code repository content and his- tory is important but can be difficult due to the complexity of code repositories. Most available tools are designed for users who are actively maintaining a code repository. In contrast, external developers need to assess the suitability of using a software library, e.g. whether its code repository has a healthy level of maintenance, and how much risk the external developers face if they depend on that code in their own project. In this paper, we identify six risks associated with using a software library, we derive seven requirements for tools to assess these risks, and we con- tribute two dashboard designs derived from these requirements. The first dashboard is designed to asses a software library's usage suitability via its code repository, and the second dashboard visually compares usage suitability information about multiple soft- ware libraries’ code repositories. Using four popular libraries code repositories, we show that these dashboards are effective for understanding and comparing key aspects of software library us- age suitability. We further compare our dashboard to a typical code repository user interface and show that our dashboard is more succinct and requires less work.

Background: Researchers developing health-related tools for patients and families employ a range of approaches to involve prospective users in design and development.Objective: To develop a validated measure of the human- or user-centeredness of design and development processes for patient-centered tools.Design: Cross-sectional data from a previous systematic review of the design and development processes of 348 tools.Methods: Using a conceptual framework of user-centered design, our team of patients, caregivers, health professionals, tool developers, and researchers analyzed how specific practices in tool design and development might be combined and used as a measure. We prioritized variables according to their importance within the conceptual framework and validated the resultant measure using principal component analysis with Varimax rotation, classical item analysis, and confirmatory factor analysis.Results: We retained 11 items in a 3-factor structure explaining 68% of the variance in the data. Cronbach’s alpha was .72. Confirmatory factor analysis supported our hypothesis of a latent construct of user-centeredness. Items were whether or not: (1) patient, family, caregiver or surrogate users were involved in steps to understand users or (2) develop a prototype, (3) asked their opinions, (4) observed using the tool, or (5) involved in steps intended to evaluate the tool, (6) the process had three or more iterative cycles, (7) changes between cycles were explicitly reported, (8) health professionals were asked their opinion, (9) consulted before a first prototype was developed or (10) between initial and final prototypes, and (11) a panel of other experts was involved.Conclusion: The measure UCD-11 may be used to quantitatively document the user- and human-centeredness of design and development processes of patient-centered tools. By building an evidence base about such processes, we can help ensure that tools are adapted to the people who will use them, rather than requiring people to adapt to tools.

The phenomenon of sample impoverishment during particle filtering always contribute computation burden to the inertial-based mobile IPS systems. This is due to the factor of noise measurement and number of particle. Usually, the special strategies resampling algorithms was used. However, these algorithms just can fit in certain environment. This needs an adaptation of noise measurement and number of particle in a algorithm in order to make resampling with more intelligence, reliability and robust. In tbis paper, we will propose an adaptive special strategies resampling by adapting noise and particle measurement. These adaptation is used to determine the most suitable algorithm of special strategies resampling, that can be switched for resampling purpose. Finally, we illustrate our proposed solution our for indoor environment setup.

Hubungan antar pemeluk agama di Indonesia tidak selalu harmonis. Perbedaan ataupun ciri khas yang terdapat pada agama-agama dipertentangkan bahkan dibentur-benturkan oleh beberapa pihak dengan tujuan membenarkan salah satu agamanya. Misalnya saja dewasa ini beberapa figur yang tampil sebagai debater agama kelas dunia baik dari kalangan Islami ataupun Kristiani seperti: Christian Prince, Sam Shamoun, David Wood, Zakir Naik, Shabir Ally, Muhammad Hijab, dan seterusnya.Penulis meyakini bahwa untuk membangun kerukunan antar pemeluk agama tidaklah benar saling membenturkan ajaran ataupun praktek keagamaan pada masing-masing agama. Dialog antar pemeluk agama yang bermuatan membentur-benturkan isi dari sebuah agama hanyalah akan memecah-belah rasa persaudaraan di antara umat manusia. Oleh sebab itu dialog antar pemeluk agama seharusnya berorientasi pada usaha untuk membina rasa cinta kasih persaudaraan sehingga ada sikap saling memahami antar pemeluk agama. Hal itu bisa diwujudkan dengan atau melalui berbagai dialog iman ataupun dialog karya dimana seseorang pada tiap-tiap agama dapat menyharingkan pengalaman imannya ataupun bekerjasama untuk mengadakan aksi sosial. Kalaupun toh dialog antar pemeluk agama diadakan terkait doktrin ataupun praktek keagamaan pada masing-masing agama, maka hendaknya dialog itu dicari hal-hal yang terarah pada usaha untuk mencari kemiripan ataupun titik temu antar pemeluk agama. Sedangkan unsur yang berbeda dalam agama-agama hendaknya dipandang sebagai kekhasan pada masing-masing agama yang seyogyanya dihormati oleh setiap pemeluk agama.
Kearifan Masyarakat Jawa Pra Modern di Lembah Progo dalam Pengenalan Bentanglahan untuk Lokasi Permukiman: Tinjauan Studi Geoarkeologi

Published: June 2019

Sejak masa lampau kehidupan manusia tidak pernah terlepas dari karakteristik fisik bentanglahan sebagai lingkungan tempat tinggalnya. Dari waktu ke waktu pada berbagai tingkat peradaban, manusia cenderung memilih tempat dengan sumberdaya alam tinggi sebagai lokasi hunian. Berdasarkan konsep dalam geomorfologi yang menyatakan bahwa “the present is the key to the past”, maka dengan kajian bentanglahan saat ini dapat diduga dan direkonstruksi kondisi bentanglahan pada masa lampau. Disamping itu evolusi bentanglahan membutuhkan waktu sangat lama hingga ratusan ribu tahun atau jutaan tahun, sehingga bentanglahan pada masa peradaban masyarakat pra modern diduga tidak terlalu jauh berbeda dengan kondisi saat ini. Identifikasi pemilihan lokasi hunian pada masa lampau dengan memperhatikan aspek bentangahan dan perlapisan batuan yang menyusun bentanglahan merupakan salah satu aspek kajian dalam geoarkeologi, dan geomorfologi memiliki peranan dalam kajian ini

Open Digital Repositories: Prospects of African Countries within the Global Information Space
Authors: Ogungbeni John I. , Obiamalu Amaka Raymonda , Udem Obiora Kingsley
Published: June 2019

This study examines the contributions of African countries to open digital repositories in the world information space. Two online directories of open digital repositories were used as data sources. The OpenDOAR is an authoritative directory of academic open access repositories listing 3,670 repositories as at 6th January, 2019. The Registry of Open Access Repositories (ROAR) is a directory of 4,580 institutional repositories and their contents as at 7th January, 2019. Extracted data were analysed using quantitative techniques and presented in tabular and pictorial formats to reveal findings in accordance with desired objectives. The results revealed that Dspace is the most preferred open digital repositories software across the world. The results showed that the contributions of African countries (3.78%) to open digital repositories in the world are low. The results also showed that only 22 African countries contribute to global open digital repositories and that the rate of contribution increased rapidly in the last few years. The study concludes that for Africa to overcome the challenges associated with open digital repositories there is need for more African countries to be involved in the African Open Access Initiative and the need to tap into the experiences of various professionals on the African continent
Mindfulness training reduces PTSD symptoms and other stress-related health outcomes in police officers
Authors: Grupe Daniel W , McGehee Chad , Smith Chris , Francis Andrew , Mumford Jeanette , Davidson Richard J
Published: June 2019

BACKGROUND. Police officers are exposed daily to high levels of organizational and operational stressors that have a negative impact on health and well-being outcomes. This population has elevated rates of cardiovascular disease, sleep disorders, symptoms of depression and post-traumatic stress disorder (PTSD), and suicide. Although there are few empirically supported effective stress reduction interventions in police officers, recent evidence suggests that an 8-week training program in mindfulness meditation, specifically tailored for this group, has promise in reducing perceived stress and improving stress-related physical and mental health outcomes including sleep disturbances, anxiety, depression, and burnout. The primary aims of the current study were to 1) demonstrate the feasibility, acceptability, and adherence of a similar mindfulness training program in a new population of police officers; 2) replicate previously demonstrated improvements in perceived stress and stress-related health outcomes, and 3) provide novel evidence of hypothesized reductions in symptoms of PTSD.METHODS. We enrolled 30 sworn law enforcement personnel from a mid-sized, Midwestern U.S. police department in an 8-week, group-based mindfulness training program. We conducted in-person assessments immediately before and after the training program, consisting of self-report measures of perceived stress, sleep quality, physical and mental health symptoms, and burnout and the assessment of high-sensitivity C-reactive protein (hs-CRP) and other physical health measures. An abbreviated remote assessment at 5-month follow-up included self-report measures only.RESULTS. All 30 officers completed the 8-week program and both in-person assessments, with high rates of class attendance, substantial out-of-class practice time, and uniformly positive evaluations of the training program and instructors. Replicating previous studies, we identified post-training reductions in perceived organizational and operational stress, global sleep disturbances, anxiety, and burnout, with significant reductions in anxiety and perceived stress observed at 5-month follow-up. We also identified novel evidence for reduced PTSD hyperarousal symptoms that persisted at 5-month follow-up, and reduced re-experiencing PTSD symptoms at 5-month follow-up only. There was no evidence for changes in self-reported physical health symptoms or hs-CRP.CONCLUSIONS. Successful adaptation, delivery, and acceptance of this mindfulness-based intervention demonstrates the generalizability of mindfulness training across law enforcement populations. The replication of improved stress-related outcomes, and novel evidence for reduced PTSD symptoms, indicate important targets to be further investigated in larger, mechanistic, randomized controlled trials of mindfulness training in police officers.
Idea Generation and Goal Derived Categories
Authors: Hass Rick
Published: June 2019

Semantic search and retrieval of information plays an important role in creative idea generation. This study was designed to examine how semantic and temporal clustering varies when asking participants to generate ideas about uses for objects compared with generating members of goal-derived categories. Participants generated uses for three objects: brick, hammer, picture frame, and also generated members of the following goal-derived categories: things to take in case of a fire, things to sell at a garage sale, and ways to spend lottery winnings. Using response-time analysis and semantic analysis, results illustrated that all six prompts generally led to exponentialcumulative response-time distributions. However, the proportion of temporally clustered responses, defined using the slope-difference algorithm, was higher for goal-derived category responses compared with object uses. Despite that, overall pairwise semantic similarity was higher for object uses than for goal derived exemplars. The effect of prompt on pairwise semantic similarity is likely the result of context-dependency of exemplars from goal-derived categories. However, the current analysis contains a potential confound such that special instructions to give “common and uncommon” responses were provided only for the object-uses prompts. The confound is likely minimal, but future work is necessary to illustrate the robustness of the results.

Authority fairness as contingent on intergroup attitudes: Review and expansion of relational models of procedural justice
Authors: Urbanska Karolina , Pehrson Sam , Platow Michael J. , Turner Rhiannon
Published: June 2019

Relational models of procedural justice propose that fair procedures from authorities communicate that one is an affirmed member of the society that they represent. Authorities who use principles of procedural justice are more likely to be seen as legitimate, increasing compliance and cooperation from the public. However, ensuring that authority decisions will be accepted is not necessarily a guaranteed outcome of employing fair procedures. The empirical evidence discussed here questions what drives perceptions of authority fairness and decision acceptance by considering how social identities shape fairness perceptions. We argue that understanding these processes is crucial for authorities dealing with complex intergroup-level mediations. We support these claims by presenting an experimental study conducted in the context of post-conflict relations between Catholics and Protestants in Northern Ireland. We show that people with more negative outgroup attitudes saw restrictive police actions as fairer when these actions targeted the outgroup (versus ingroup), and more strongly preferred for facilitative police decisions concerning the ingroup (versus outgroup). In contrast, people with positive outgroup attitudes did not evaluate police decisions depending on their own community belonging. The findings suggest that the nature of intergroup relations is a relevant element in responses to authority decisions. We outline new directions to theoretical developments of how authorities can effectively serve social systems that they represent.
Enhanced Memory in Synaesthesia is Primarily linked to the Familiarity Component of Recognition Memory
Authors: Ward Jamie
Published: June 2019

People with synaesthesia (e.g. letters evoking colours) have enhanced memory on many standard laboratory tasks, but relatively little is known about the underlying mechanism. In these studies we determined whether the memory advantage of synaesthetes was compromised to the same extent, and in the same way, by manipulations known to adversely affect memory. In Study 1, we employed a continuous recognition memory paradigm in which previously studied items in an early block become lures in a subsequent block, hence requiring careful monitoring of temporal context. In Study 2, we employed a standard levels-of-processing manipulation in which shallow encoded items disrupts memory performance. In both studies, participants indicated their level of confidence from which we estimated separate familiarity and recollection parameters within a dual-process framework (Yonelinas & Parks, 2007). Synaesthetes showed comparable levels of susceptibility to these memory manipulations despite having significantly better performance overall. However, whilst temporal context confusion and shallow processing affected both estimates of recollection and familiarity, the group difference between synaesthetes and controls was carried by the familiarity component alone. This suggests that the mechanisms giving rise to enhanced memory in synaesthesia loads primarily on familiarity-related processes.

While children’s voice is core to paediatric care, their own assessment of future psychological needs is under-explored. We conducted a prospective observational study among children hospitalized for injury in Melbourne, Australia. Their expectations of psychological recovery at baseline (in-hospital) were significant and substantial predictors of their quality of life and post-traumatic stress 6 weeks later, suggesting potential diagnostic value.

Policymakers can take actions to prevent local conflict before it begins, if such violence can be accurately predicted. We examine the two countries with the richest available sub-national data: Colombia and Indonesia. We assemble two decades one fine- grained violence data by type, alongside hundreds of annual risk factors. We predict violence one year ahead with a range of machine learning techniques. Models reliably identify persistent, high-violence hot spots. Violence is not simply autoregressive, as detailed histories of disaggregated violence perform best. Rich socio-economic data also substitute well for these histories. Even with such unusually rich data, however, the models poorly predict new outbreaks or escalations of violence. \Best case" scenarios with panel data fall short of workable early-warning systems.
Investigating rapid effects of motor training on the brain's gray matter volume: a magnetic resonance imaging study with repeated testing
Authors: Jafari Arian , Jenner Bo
Published: June 2019

Recent MRI studies have shown that training can cause apparent gray matter volume (GMV) increases in task-relevant brain regions within hours or even minutes. The present study examined rapid plasticity in the context of motor training, at temporal resolutions of two minutes as well as roughly one hour. Twenty-five healthy volunteers practised performing a complex finger tapping task (FTT) while inside an MRI scanner. Previous research on FTT was used to define a priori region of interest PMCROI in the primary motor cortex. GMV in PMCROI was analyzed during rest and training at three time points: beginning, middle, and end of scan. We found an increase in GMV during rest compared to training at end of scan, indicating a potential delayed training effect. Post hoc analyses of the sensorimotor network resulted in comparable effects which did not survive correction. No significant differences in training GMV between the three time points were found in PMCROI. To our knowledge, no previous study has reported changes in GMV in such a short time period (120 seconds). Future research should continue investigations with high temporal resolution to explore a potential delay in rapid effects of training on GMV.
Enterprise gamification systems and employment legislation: a systematic literature review
Authors: Hinton Sean , Wood Lincoln C. , Singh Harminder , Reiners Torsten
Published: June 2019

A recent innovation in employee motivation systems is the introduction of ‘gamification’, which refers to the use of game design mechanics and principles to influence behaviour to enhance staff motivation and engagement. Enterprise gamification systems aggravate the differences in information availability between employers and employees, and employees who may be forced to adopt such systems may be placed under stress, worsening employment relationships in the workplace. Therefore, this research examines the potential legal implications of gamified employee motivation systems. This study undertook a systematic review of enterprise gamification and then used thematic analysis coupled with a review of legislation to examine whether gamification in workplaces meets the legal obligations of employers under their ‘duty of good faith’ in the New Zealand context. We find that carefully designed enterprise gamification systems should provide sufficient information and clarity for employees and support positive employment relationships. Deployments of enterprise gamification systems should be carefully planned with employee consultation and feedback supporting the introduction of an enterprise gamification system. Future research should look beyond the ‘good faith’ obligation and examine the relationship between gamification systems and the law on personal grievances.
Mechanical properties characterization of resistance spot welded DP1000 steel under uniaxial tensile tests
Authors: Javaheri Ehsan , Pittner Andreas , Graf Benjamin , Rethmeier Michael
Published: June 2019

Resistance spot welding (RSW) is widely used in the automotive industry as the main joining method. Generally, an automotive body contains around 2000 to 5000 spot welds. Therefore, it is of decisive importance to characterize the mechanical properties of these areas for the further optimization and improvement of an automotive body structure. The present paper aims to introduce a novel method to investigate the mechanical properties and microstructure of the resistance spot weldment of DP1000 sheet steel. In this method, the microstructure of RSW of two sheets was reproduced on one sheet and on a bigger area by changing of the welding parameters, e. g. welding current, welding time, electrode force and type. Then, tensile tests in combination with digital image correlation (DIC) measurement were performed on the notched tensile specimens to determine the mechanical properties of the weld metal. The notch must be made on the welded tensile specimen to force the fracture and elongation on the weld metal, enabling the characterization of its properties. Additionally, the parameters of a nonlinear isotropic material model can be obtained and verified by the simulation of the tensile specimens. The parameters obtained show that the strength of DP1000 steel and the velocity of dislocations for reaching the maximum value of strain hardening, are significantly increased after RSW. The effect of sample geometry and microstructural inhomogeneity of the welded joint on the constitutive property of the weld metal are presented and discussed.

In this study, AISI 1050 steel was boronized at temperatures of 800, 850, 900, 950 and 1000 °C for 3, 6, and 9 hours by means of a pack boronizing process. The formation of the boride layer was investigated. The characterization of the boronized surfaces was determined by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Although dual phase, FeB and Fe2B were observed in the boride layer, the intensity of the FeB was slight and collected only near the outer surface which is the desired structural morphology. As the boronizing temperature and holding time strongly affect the results of both boride layer thickness and the surface hardness of the material, multi-objective mathematical models were developed for optimization. Energy consumption during boronizing was also considered. Hence, the optimum values for both temperature and holding time were determined, both of which maximize surface hardness and boride layer thickness while minimizing energy consumption.

Published: June 2019

Hard ceramic particle reinforced aluminum matrix composites (AMCs) are considered a distinct category of advanced materials which command outstanding strength, good corrosion resistance and excellent wear resistance compared to conventional materials. In the present work, an Al-Zn-Mg aluminum alloy-based metal matrix composite was prepared by stir casting. The AA7075 matrix was reinforced with 0, 3, 6, 9 and 12 wt.-% aluminum nitride particles for producing AMCs. Flexural strength, tensile strength and micro-hardness were studied. The microstructure of the matrix alloy and the composites was examined by scanning electron microscopy (SEM). Micron-sized aluminum nitride particles were added to the aluminum matrix to enhance the micro-hardness and the flexural and tensile strength of the composite. SEM micrographs reveal the fairly uniform dissemination of aluminum nitride particles in the composite. The results obtained indicate that the mechanical properties of the composite were increased with an increase in weight percentages of the aluminum nitride reinforcement content.
