This article study the discrepancy between theory and practice, especially the roles play by Land Office and Forestry Department in term of overlapping of power and penalties between Land Office and Forestry Department especially the forest on the state land leading to susceptibility in monitoring and enforcement system. The whole empirical works took place in the Central Region of Peninsular Malaysia namely as Negeri Sembilan. The total area of permanent reserved forest in that state is 155,531 hectares including the Permanent Reserved Forest Johol which was selected as the case study in this research. An exploratory research design was adopted in this research. Therefore, in-depth interviews have been done with officers from the Land Office and Forestry Department regarding their role and powers in monitoring and enforcement system to combat forest offences in Permanent Reserved Forest Johol. While data collected was analyzed using the descriptive analysis method. Content analysis was used to identify the similarities and dissimilarities of acts that empower Land Office and Forestry Department to taking action against forest offences. Theoretically, there are overlapping powers occurs between Land Office and Forestry Department identified in National Land Code 1965 and National Forestry Act 1984 in terms of arrestment of the forest offenders and seized their equipment. However, penalties imposed by both acts are very different. Practically, both authorities have divided their responsibility and power accordingly to avoid overlapping. Issues and challenges that faced by them have been found and most of them are similar. There should be an amendment to the acts in terms of the penalty imposed by both authorities. The penalty stated in both acts should be synchronized or the related sections be removed if the authorities do not implement it practically to avoid overlapping and conflicting of action imposed between two acts.Keywords: state land, forest, forest offences, penalties, monitoring, enforcement, overlapping of powerCitation: Azizan, M.U., Bing, T.S., Raid, M.M., Mohammad, M.T.S, Hussin, K., Rahman, M.M.G.A., and Nadzri, M.I.

There has been increasing academic interest in understanding the nature of parental involvement in youth sport. Much scholarly focus has illuminated both positive and negative forms of sport parenting from the perspectives of coaches, parents and youth participants. One less understood aspect however surrounds the potentially conflicting role of parents who coach their own children in youth sport. This is surprising given that many parents, especially fathers, demonstrate support by fulfilling essential roles such as team manager and team coach (Jeffery-Tosoni, Fraser-Thomas, & Baker, 2015). This paper emerges from an Australian study of 16 parent-coaches involved in Australian football. The original purpose of the study was to understand the nature of the sport parenting role in youth sport in Australia. A number of pertinent themes were constructed surrounding the contemporary experiences of parent-coaches who coach their own children, and how coaching is subsequently justified. The findings illustrate how concerns of favouritism impact how parent-coaches interact with their child in contrast to the rest of the team, encouraging nuances of ‘negative’ parenting toward their own children under the guise of being the coach. Examples of this include demonstrating deliberate criticism at training and matches and overlooking their child in awarding encouragement awards after each weekly match. Significantly, parent-coaches justify these behaviours in attempting to fulfil the dual role of parent and team coach. We argue that this can be potentially problematic for some parent and child relationships and have a reinforcing influence on how other parent-coaches negotiate being a parent and coach.

Abstract Today, cancer is one of the leading causes of death worldwide. Lately, cytokine and chemokine imbalances have gained attention amongst different involved pathways in cancer development and attracted much consideration in cancer research. CXCL16, as a member of the CXC subgroup of chemokines, has been attributed to be responsible for immune cell infiltration into the tumour microenvironment. The aberrant expression of CXCL16 has been observed in various cancers. This chemokine has been shown to play a conflicting role in tumour development through inducing pro-inflammatory conditions. The infiltration of various immune and non-immune cells such as lymphocytes, cancer-associated fibroblasts and myeloid-derived suppressor cells by CXCL16 into the tumour microenvironment has complicated the tumour fate. Given this diverse role of CXCL16 in cancer, a better understanding of its function might build-up our knowledge about tumour biology. Hence, this study aimed to review the impact of CXCL16 in cancer and explored its therapeutic application. Consideration of these findings might provide opportunities to achieve novel approaches in cancer treatment and its prognosis.

AbstractAll organisms regulate the transcription of their genes. To understand this process, it is essential to know how transcription factors find their targets in the genome. In addition to the DNA sequence, several variables have a known influence, but overall the binding patterns of transcription factors distribution remains mostly unexplained in animal genomes. Here we investigate the role of the chromosome conformation in shaping the search path of transcription factors. Using molecular dynamics simulations, we uncover the main principles of their diffusion on folded chromatin. Chromosome contacts play a conflicting role: at low density they enhance the traffic of transcription factors, but a high density they lower the traffic by volume exclusion. Consistently, we observe that in human cells, highly occupied targets, where protein binding is promiscuous, are found at sites engaged in chromosome loops within uncompact chromatin. In summary, those results provide a theoretical framework to understand the search trajectories of transcription factors and highlight the key contribution of genome conformation.
